PRESENTATION OF FINANCIAL INFORMATION

The selected financial information as of December 31, 2018 and 2017 and for the years ended December 31, 2018, 2017 and 2016 is derived from, and qualified in its entirety by reference to, our Annual Consolidated Financial Statements, which are included elsewhere in this annual report and prepared in accordance with IFRS as issued by the IASB. The selected financial information as of December 31, 2016 and 2015 and for the years ended December 31, 2015 and 2014, is derived from, and qualified in its entirety by reference to, the annual consolidated financial statements as of December 31, 2017 and 2016 and for the years ended December 31, 2017, 2016 and 2015, which are included in the annual report on Form 20-F filed with the SEC on March 7, 2018, and prepared in accordance with IFRS as issued by the IASB. The selected financial information as of December 31, 2014 is derived from, and qualified in its entirety by reference to, the annual consolidated financial statements as of December 31, 2016 and 2015 and for the years ended December 31, 2016, 2015 and 2014, which are included in the annual report on Form 20-F filed with the SEC on February 28, 2017, and prepared in accordance with IFRS as issued by the IASB.

On June 18, 2014, we closed our IPO. Prior to the consummation of our IPO, Abengoa contributed, through a series of transactions, which we refer to collectively as the “Asset Transfer,” certain contracted and concessional assets and liabilities described in this annual report, certain holding companies and a preferred equity investment in ACBH. For the period in 2014 prior to our IPO, the financial information herein represents the combination of the assets that we acquired and was prepared using Abengoa’s historical basis in the assets and liabilities and the term “Atlantica Yield” (or “Abengoa Yield,” our former name) represents the accounting predecessor, or the combination of the acquired businesses. For all periods subsequent to our IPO, the financial information herein represents our and our subsidiaries’ annual consolidated financial results.

Certain numerical figures set out in this annual report, including financial data presented in millions or thousands and percentages describing market shares, have been subject to rounding adjustments, and, as a result, the totals of the data in this annual report may vary slightly from the actual arithmetic totals of such information. Percentages and amounts reflecting changes over time periods relating to financial and other data set forth in “Item 5.A—Operating and Financial Review and Prospects—Operating Results” are calculated using the numerical data in our Annual Consolidated Financial Statements or the tabular presentation of other data (subject to rounding) contained in this annual report, as applicable, and not using the numerical data in the narrative description thereof.

Table of Contents

Non-GAAP Financial Measures

This annual report contains non-GAAP financial measures including Further Adjusted EBITDA.

Our management believes Further Adjusted EBITDA is useful to investors and other users of our financial statements in evaluating our operating performance because it provides them with an additional tool to compare business performance across companies and across periods. This measure is widely used by investors to measure a company’s operating performance without regard to items such as interest expense, taxes, depreciation and amortization, which can vary substantially from company to company depending upon accounting methods and book value of assets, capital structure and the method by which assets were acquired. This measure is widely used by other companies in the same industry.

Our management uses Further Adjusted EBITDA as a measure of operating performance to assist in comparing performance from period to period on a consistent basis and to readily view operating trends, as a measure for planning and forecasting overall expectations and for evaluating actual results against such expectations, and in communications with our board of directors, shareholders, creditors, analysts and investors concerning our financial performance.

We present non-GAAP financial measures because we believe that they and other similar measures are widely used by certain investors, securities analysts and other interested parties as supplemental measures of performance and liquidity. The non-GAAP financial measures may not be comparable to other similarly titled measures of other companies and have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our operating results as reported under IFRS as issued by the IASB. Non-GAAP financial measures and ratios are not measurements of our performance or liquidity under IFRS as issued by the IASB and should not be considered as alternatives to operating profit or profit for the year or any other performance measures derived in accordance with IFRS as issued by the IASB or any other generally accepted accounting principles or as alternatives to cash flow from operating, investing or financing activities.

Some of the limitations of these non-GAAP measures are:

they do not reflect our cash expenditures or future requirements for capital expenditures or contractual commitments;

they do not reflect changes in, or cash requirements for, our working capital needs;

they may not reflect the significant interest expense, or the cash requirements necessary, to service interest or principal payments, on our debts;

although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often need to be replaced in the future and Further Adjusted EBITDA does not reflect any cash requirements that would be required for such replacements;

some of the exceptional items that we eliminate in calculating Further Adjusted EBITDA reflect cash payments that were made, or will be made in the future; and

Table of Contents

the fact that other companies in our industry may calculate Further Adjusted EBITDA differently than we do, which limits their usefulness as comparative measures.

Further Adjusted EBITDA ^(2)(3)(4)		850.6		779.3		763.3		624.2		308.0

Note:

(1)	Further Adjusted EBITDA for EMEA does not include our pro rata share of EBITDA from unconsolidated affiliates, which was $8.1 million, $7.3 million, $8.8 million, $12.3 million and $0 million for the years ended December 31, 2018, 2017, 2016, 2015 and 2014.

(2)

Further Adjusted EBITDA is a supplemental non-GAAP financial measure. We present non-GAAP financial measures because we believe that they and other similar measures are widely used by certain investors, securities analysts and other interest parties. The non-GAAP financial measures may not be comparable to other similarly titled measures of other companies and have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our operating results as reported under IFRS as issued by the IASB. Non-GAAP financial measures are not measurements of our performance or liquidity under IFRS as issued by the IASB and should not be considered as alternatives to operating profit or profit for the year or any other performance measure derived in accordance with IFRS as issued by the IASB or any other generally accepted accounting principles. See “Presentation of Financial Information—Non-GAAP Financial Measures.”

(3)

Further Adjusted EBITDA is calculated as profit/(loss) for the year attributable to the parent company, after adding back loss/(profit) attributable to non-controlling interest from continued operations, income tax, share of profit/(loss) of associates carried under the equity method, finance expense net, depreciation, amortization and impairment charges of entities included in the Annual Consolidated Financial Statements, and dividends received from our preferred equity investment in ACBH. Further Adjusted EBITDA for 2014, includes preferred dividends by ACBH for the first time during the third and fourth quarters of 2014. Further Adjusted EBITDA for 2016 and the first quarter of 2017 includes compensation received from Abengoa in lieu of ACBH dividends. Further Adjusted EBITDA is not a measure of performance under IFRS as issued by the IASB and you should not consider Further Adjusted EBITDA as an alternative to operating income or profits or as a measure of our operating performance, cash flows from operating, investing and financing activities or as a measure of our ability to meet our cash needs or any other measures of performance under generally accepted accounting principles. We believe that Further Adjusted EBITDA is a useful indicator of our ability to incur and service our indebtedness and can assist securities analysts, investors and other parties to evaluate us. Further Adjusted EBITDA and similar measures are used by different companies for different purposes and are often calculated in ways that reflect the circumstances of those companies. Further Adjusted EBITDA may not be indicative of our historical operating results, nor is it meant to be predictive of potential future results.

(4)	Further Adjusted EBITDA does not include our pro rata share of EBITDA from unconsolidated affiliates, which was $8.1 million, $7.3 million, $8.8 million, $12.3 million and $0 million for the years ended December 31, 2018, 2017, 2016, 2015 and 2014.

Risks Related to Our Business and the Markets in Which We Operate

Difficult conditions in the global economy and in the global capital markets have caused, and may continue to cause, a sharp reduction in worldwide demand for our products and services.

Our results of operations have been, and continue to be, materially affected by conditions in the global economy. In the United States, capital markets have been experiencing some volatility recently probably driven by signs of a global economic slowdown, concerns on upcoming decisions on interest rates, inflation fears and trade tensions with China. Concerns over inflation, volatile oil and gas prices, geopolitical issues, the availability and cost of credit, sovereign debt and the instability of the euro have contributed to increased volatility and diminished expectations for the economy and global capital markets going forward. These factors have in the past precipitated economic slowdowns and led to a recent recession and weak economic growth. Adverse events and continuing disruptions in the global economy and in the global capital markets may have a material adverse effect on our business, financial condition, results of operations and cash flows. Moreover, even in the absence of a market downturn, we are exposed to substantial risk of loss due to market volatility with certain factors, including volatile oil prices, interest rates, consumer spending, business investment, government spending, inflation affecting the business and economic environment that could affect the economic and financial situation of our concession contracts counterparties and, ultimately, the profitability and growth of our business.

Generalized or localized downturns or inflationary or deflationary pressures in our key geographical areas could also have a material adverse effect on our business, financial condition, results of operations and cash flows. A significant portion of our business activity is concentrated in the United States, Mexico, Peru and Spain. Consequently, we are significantly affected by the general economic conditions in these countries. Spain, for instance, has experienced negative economic conditions in the last few years, including high unemployment and significant government debt, increased lately by the uncertainty of the Catalonian political situation, which we believe could adversely affect our operations in the future. The effects on the European and global economy of the exit of the United Kingdom from the European Union or of any other member states from the Eurozone, the dissolution of the euro, or the perception that any of these events are imminent, are inherently difficult to predict and could give rise to operational disruptions or other risks of contagion to our business and have a material adverse effect on our business, financial condition, results of operations and cash flows. In addition, to the extent uncertainty regarding the European economic recovery continues to negatively affect government or regional budgets, our business, results of operations and cash flows could be materially adversely affected. Various European political parties who question the recent austerity policies implemented in certain European countries have added political instability to the region. Finally, the next elections to the European Parliament are expected to be held in May 23-26, 2019, and the result may have an impact on government or regional budgets.

Additionally, political changes in key geographies, including the United States, could affect our business in the United States or in other countries including, for example, Mexico.

We may not be able to arrange the required or desired financing for acquisitions and for the successful refinancing of the Company’s project level and corporate level indebtedness.

The global capital and credit markets have experienced in the past and may continue to experience periods of extreme volatility and disruption. During the second half of 2015 and first half of 2016, our access to financing was curtailed by market conditions and other factors. Starting at the end of 2018 and continuing in the beginning of 2019, it has been a period of high volatility in capital markets, particularly in the United States and Europe. These adverse market conditions could prevent us from accessing the capital markets in a manner that would permit the Company to make acquisitions or refinance its debt on satisfactory terms or at all, including the 2019 Notes maturing in November 2019. Continued disruptions, uncertainty or volatility in the global capital and credit markets may limit our access to additional capital required to operate or grow our business, including our access to new debt and equity capital to make further acquisitions or access to project debt, which we may use to fund or refinance many of our projects and corporate level debt, even in cases where such capital has already been committed. Such market conditions may limit our ability to replace, in a timely manner, maturing liabilities and access the capital necessary to grow our business, or replace financing previously committed for a project that ceases to be available to us. As a result, we may be forced to delay raising capital, issue shorter-term securities than we prefer, or bear a higher cost of capital which could decrease our profitability and significantly reduce our financial flexibility or even require us to modify our dividend policy. In the event we are required to replace previously committed financing to certain projects that subsequently becomes unavailable, we may have to postpone or cancel planned acquisitions or capital expenditures. The inability to raise capital, higher costs of capital or postponement or cancellation of planned acquisitions or capital expenditures may have a materially adverse effect on our business, results of operations and cash flows. In addition, our ability to arrange financing, either at the corporate level or at a non-recourse project level subsidiary, and the costs of such capital, are dependent on numerous factors, including:

general economic and capital market conditions;

credit availability from banks and other financial institutions;

investor confidence in us and Algonquin as our largest shareholder

our financial performance and the financial performance of our subsidiaries;

our level of indebtedness and compliance with covenants in debt agreements;

maintenance of acceptable project credit ratings or credit quality;

cash flow; and

provisions of tax and securities laws that may impact raising capital.

We may not be successful in obtaining additional capital for these or other reasons. Furthermore, we may be unable to refinance or replace project level financing arrangements or other credit facilities on favorable terms or at all upon the expiration or termination thereof. Our failure, or the failure of any of our projects, to obtain additional capital may constitute a default under such existing indebtedness and may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Counterparties to our offtake agreements may not fulfill their obligations and, as our contracts expire, we may not be able to replace them with agreements on similar terms in light of increasing competition in the markets in which we operate.

A significant portion of the electric power we generate, the transmission capacity we have, and our desalination capacity is sold under long-term offtake agreements with public utilities, industrial or commercial end-users or governmental entities, with a weighted average remaining duration of approximately 18 years as of December 31, 2018.

If, for any reason, including, but not limited to, a deterioration in their financial situation or bankruptcy, any of the purchasers of power, transmission capacity or desalination capacity under these agreements are unable or unwilling to fulfill their related contractual obligations or if they refuse to accept delivery of power delivered thereunder or if they otherwise terminate such agreements prior to the expiration thereof, or if prices were re-negotiated under a bankruptcy situation, or if they delayed payments, our assets, liabilities, business, financial condition, results of operations and cash flow may be materially adversely affected. Furthermore, to the extent any of our power, transmission capacity or desalination capacity purchasers are, or are controlled by, governmental entities, our facilities may be subject to sovereign risk or legislative or other political action that may hamper their contractual performance.

On January 29, 2019, PG&E, the off-taker for Atlantica Yield with respect to the Mojave plant, filed for reorganization under Chapter 11 of the Bankruptcy Code in the U.S. Bankruptcy Court for the Northern District of California (the “Bankruptcy Court”). As a consequence, PG&E has not paid the portion of the invoice corresponding to the electricity delivered for the period between January 1 and January 28, 2019, which was due on February 25, given that the services relate to the pre-petition period and any payment therefore would require approval by the Bankruptcy Court. However, PG&E has paid the portion of the invoice corresponding to the electricity delivered after January 28. A default of the PPA agreement with PG&E occurred with the PG&E bankruptcy filing and such default could trigger an event of default under our Mojave project finance agreement if certain other conditions were met, namely if (i) such default could reasonably be expected to result in a material adverse effect to Mojave or (ii) PG&E failed to assume the PPA within 60 days of its chapter 11 filing, extendable to 180 days provided that PG&E continues to perform under the PPA. As of December 31, 2018, Mojave had $739 million outstanding under its project financing agreement with the Federal Financing Bank, with a guarantee from the DOE. Additionally, Mojave represents approximately 13.5% of 2018 project level cash available for distribution. Chapter 11 bankruptcy is a complex process and we do not know at this time whether PG&E will seek to reject the PPA or not. However, PG&E has continued to be in compliance with the remaining terms and conditions of the PPA, including with all payment terms of the PPA up through the date hereof with the exception of services for prepetition services that became due and payable after the chapter 11 filing date. It remains possible that at any time during the chapter 11 proceeding, PG&E may decide to cease performing under the PPA and attempt to reject or renegotiate the terms of its contract with us. If PG&E rejected the contract and stopped making payments in accordance with the PPA, Mojave could fail in servicing its debt under its project finance agreement, which would also cause a default under the project finance agreement. If not cured or waived, an event of default in the project finance agreement could result in debt acceleration and, if such amounts were not timely paid, the DOE could decide to foreclose on the asset. The PG&E bankruptcy has heightened the risk that project level cash distributions could be restricted for an undetermined period of time, thereby impacting our corporate liquidity and corporate leverage. Mojave project cash distributions to the corporate level normally takes place at the end of the year, the last distribution received at the corporate level took place in December 2018. Unless the event or default is cured or waived, distributions may not be made during the pendency of the bankruptcy. Such events may have a material adverse effect on our business, financial condition, results of operations and cash flows.

During recent months, the credit rating of Eskom has also weakened and is currently CCC+ from S&P Global Rating (“S&P”), B2 from Moody’s Investor Service Inc. (“Moody’s”) and BB- from Fitch Ratings Inc. (“Fitch”). Eskom is the offtaker of our Kaxu solar plant, a state-owned, limited liability company, wholly owned by the government of the Republic of South Africa. Eskom’s payment guarantees to our solar plant Kaxu are underwritten by the South African Department of Energy, under the terms of an implementation agreement. The credit ratings of the Republic of South Africa as of the date of this report are BB/Baa3/BB+ by S&P, Moody’s and Fitch, respectively.

The cost of renewable energy has considerably decreased over the past years, becoming a consistently competitive source of power generation compared to traditional fossil fuels in many regions, and it is expected to continue falling in the future. In addition, there has been an increase in the number of players and competition in the renewable energy space in the last few years, industrial companies and other independent power producer as well as large infrastructure funds and other financial players. The reduction in the cost of renewable energy and the intense competition has contributed to a reduction in electricity prices paid by the off-takers. In light of these market conditions, we may not be able to replace an expiring or terminated agreement with an agreement on equivalent terms and conditions, including at prices that permit operation of the related facility on a profitable basis. In addition, we believe many of our competitors have well-established relationships with our current and potential suppliers, lenders and customers and have extensive knowledge of our target markets. As a result, these competitors may be able to respond more quickly to evolving industry standards and changing customer requirements than us. Adoption of technology more advanced than our own could reduce the power production costs of our competitors, resulting in their having a lower cost structure than is achievable with the technologies we currently employ and adversely affect our ability to compete for offtake agreement renewals. If we are unable to replace an expiring or terminated offtake agreement, the affected facility may temporarily or permanently cease operations. External events, such as a severe economic downturn, could also impair the ability of some counterparties to our offtake agreements and other customer agreements to pay for energy and/or other products and services received.

Table of Contents

Our inability to enter into new or replacement offtake agreements or to compete successfully against current and future competitors in the markets in which we operate may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Government regulations could change at any time and such changes may negatively impact our current business and our growth strategy.

In some of our assets such as the Spanish solar plants and one of our transmission lines in Chile, revenues are based on existing regulation. We may also acquire in the future additional assets or businesses with regulated revenues. For these types of assets and businesses, if regulation changes, it may have a material adverse effect on our business, financial condition, results of operations and cash flows.

In addition, our strategy to grow our business through the acquisition of renewable energy projects partly depends on current government policies that promote and support renewable energy and enhance the economic viability of owning solar and wind energy projects. Renewable energy projects currently benefit from various U.S. federal, state and local governmental incentives, such as ITCs, PTCs, loan guarantees, RPS programs, or MACRS along with other incentives. These policies have had a significant impact on the development of renewable energy and they could change at any time, especially in the event that the current administration was to embark on further significant changes in federal energy policy. The current U.S. administration has also made public statements regarding overturning or modifying policies of, or regulations enacted by, the prior administration that placed limitations on coal and gas electric generation, mining and/or exploration. Additionally, many of these government incentives, including the ITCs and the PTCs, are subject to phase-out and/or expiration. These incentives make the development of renewable energy projects more competitive by providing tax credits, accelerated depreciation and expensing for a portion of the development costs, decreasing the costs associated with developing such projects or creating demand for renewable energy assets through RPS programs. A loss or reduction in such incentives or the value of such incentives, a change in policy away from limitations on coal and gas electric generation, mining and exploration, or a reduction in the capacity of potential investors to benefit from such incentives could decrease the attractiveness of solar or renewable energy projects to project developers, and the attractiveness of solar energy systems to utilities, retailers and customers. Such a loss or reduction could also reduce our acquisition opportunities and our willingness to pursue renewable energy projects due to higher operating costs or lower revenues from offtake agreements. See also “—Risks Related to Taxation.”

The current U.S. administration’s environmental and tax policies may create regulatory uncertainty in the clean energy sector and may lead to a reduction or removal of various clean energy programs and initiatives designed to curtail climate change. Such a reduction or removal of incentives may diminish the market for future renewable energy offtake agreements and reduce the ability for renewable developers to compete for future energy offtake agreements, which may reduce incentives for project developers to invest in the development and construction of clean energy and water infrastructure contracted assets. To the extent that these policies are changed in a manner that reduces the incentives or the value of such incentives or reduces the capacity of potential investors to benefit from such incentives, this could cause reduced revenues and reduced economic returns, resulting in increased financing costs and difficulty in obtaining financing.

The reduction in the corporate tax rate diminishes the benefit of tax incentives for potential investors and reduces the value of accelerated depreciation deductions and the expensing of certain capital expenditures. Any effort to overturn federal and state laws, regulations or policies that are supportive of existing or new solar energy generation or that remove costs or other limitations on other types of generation that compete with solar energy projects could materially and adversely affect the Company’s business. Additionally, the current U.S. administration has explored potential legal and regulatory strategies to subsidize coal and nuclear generation, which could allow those technologies to become more cost competitive relative to renewable generation sources.

Additionally, some U.S. states with RPS targets have met, or in the near future will meet, their renewable energy targets. For example, California, which has among the most aggressive RPS laws in the United States, is poised to meet its current mandate of 33.0% renewable energy by 2020 with already-proposed new renewable energy projects, though significant additional investments will be required to meet the higher renewable energy mandate of 60.0% by 2030 and 100% by 2045 that was adopted in 2018. If, as a result of achieving these targets, these and other U.S. states do not increase their targets in the near future, demand for additional renewable energy could decrease.

Table of Contents

In addition, the substantial increase of grid connected intermittent solar and wind generation assets resulting from the adoption of RPS targets has created significant technical challenges for grid operators. As a result, RPS targets may need to be scaled back or delayed in order to develop technologies or infrastructure to accommodate this increase in intermittent generation assets.

We rely, in a significant part, on environmental and other regulations of industrial and local government activities, including regulations mandating, among other things, reductions in carbon or other greenhouse gas emissions or use of energy from renewable sources. If the businesses to which such regulations relate were deregulated or if such regulations were materially changed or weakened, the profitability of our current and future projects could suffer, which could in turn have a material adverse effect on our business, financial condition, results of operations and cash flows. In addition, uncertainty regarding possible changes to any such regulations has adversely affected us in the past, and may adversely affect in the future, our ability to refinance a project or to satisfy other financing needs.

Subsidy regimes for renewable energy generation have been challenged in the past on constitutional and other grounds (including that such regimes constitute impermissible European Union state aid) in certain jurisdictions. In addition, certain loan-guarantee programs in the United States, including those which have enabled the DOE to provide loan guarantees to support our Solana and Mojave projects in the United States, have been challenged on grounds of failure by the appropriate authorities to comply with applicable U.S. federal administrative and energy law. If all or part of the subsidy and incentive regimes for renewable energy generation in any jurisdiction in which we operate were found to be unlawful and, therefore, reduced or discontinued, we may be unable to compete effectively with conventional and other renewable forms of energy.

We currently have two financing arrangements with the Federal Financing Bank for the Solana and Mojave assets, repayment of which to the Federal Financing Bank by those projects is with a guarantee by the DOE. Additionally, these projects benefit from the ITCs. Unilateral changes to these agreements or the ITC regime may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Potential acquisition of solar projects could be more challenging if the cost of solar panels does not decline or increases in the future, including as a result of increases in the cost of solar panels or tariffs on imported solar panels imposed by the U.S. government.

The cost of solar panels, which declined in recent years, and the raw materials necessary to manufacture them has been a key driver in the pricing of solar energy systems and customer adoption of this form of renewable energy. The U.S. government has imposed tariffs on solar cells manufactured in China, which is a large producer of solar cells, thereby increasing the price of solar panels containing Chinese-manufactured solar cells. While solar panels containing solar cells manufactured outside of China are not subject to such tariffs, the prices of these solar panels are, and may continue to be, more expensive than panels produced using Chinese solar cells, before giving effect to the tariff penalties, and such tariffs may create upward pressure on prices.

In addition, the U.S. government is conducting trade investigations relating to solar modules manufactured in China (with cells from other countries) and cells manufactured in Taiwan. In early January 2015, the U.S. government imposed preliminary tariffs on solar cells manufactured in Taiwan and solar panels and modules containing such cells. Similar measures could be taken for solar cells manufactured in China.

With the stabilization or increase of solar panel and raw materials prices, our growth could slow. Although Atlantica does not purchase solar panels directly, higher cost solar panels could reduce our willingness to pursue renewable energy projects due to higher operating costs or lower revenues from offtake agreements.

We are exposed to political, social and macroeconomic risks relating to the United Kingdom’s exit from the European Union.

On June 23, 2016, the electorate in the United Kingdom voted in favor of leaving the European Union (commonly referred to as “Brexit”), and the U.K. government invoked Article 50 of the Lisbon Treaty related to withdrawal on March 29, 2017. The withdrawal of the United Kingdom from the European Union is expected to take effect on March 29, 2019. Under Article 50, the Treaty on the European Union and the Treaty on the Functioning of the European Union cease to apply in the relevant state from the date of entry into force of a withdrawal agreement or, failing that, two years after the notification of intention to withdraw, although this period may be extended in certain circumstances. The United Kingdom and the European Union have not reached an agreement on the future terms of the United Kingdom’s relationship with the European Union. There is the potential that the United Kingdom and the European Union may not agree to a withdrawal arrangement before the date the United Kingdom leaves the European Union. Regardless of the eventual timing or terms of the United Kingdom’s exit from the EU, the result of the 2016 referendum continues to create significant political, regulatory and macroeconomic uncertainty.

There are a number of areas of uncertainty in connection with the future of the United Kingdom and its relationship with the EU. The negotiation of the United Kingdom’s exit terms and related matters may take several years. Given this uncertainty and the range of possible outcomes, it is not currently possible to determine the impact that the United Kingdom’s departure from the EU and/or any related matters may have on general economic conditions in the United Kingdom or the EU. The exit of the United Kingdom (or any other country) from the EU or prolonged periods of uncertainty relating to any of these possibilities could result in significant macroeconomic deterioration, including, but not limited to, further decreases in global stock exchange indices, increased foreign exchange volatility, decreased GDP in the European Union or other markets in which we operate, issues with cross-border trade, political and regulatory uncertainty and further sovereign credit downgrades. In addition, there could be changes to tax regulation affecting the repatriation of dividends from other countries, which may negatively affect us. Additionally, the impact of potential changes to the United Kingdom’s migration policy could adversely impact our employees of non-U.K. nationality currently working in the United Kingdom as well as have an uncertain impact on cross-border labor. The potential loss of the EU “passport,” or any other potential restrictions on free travel of UK citizens to Europe, and vice versa, could adversely impact the jobs market in general and our operations in Europe. Finally, Brexit is likely to lead to legal uncertainty in areas such as data protection, taxation, and potentially divergent national laws and regulations as the UK determines which EU laws to replace or replicate, including the GDPR. Any of these effects of Brexit, and others we cannot anticipate, could adversely affect our business, results of operations and financial condition.

We have international operations and investments, including in emerging markets that could be subject to economic, social and political uncertainties.

We operate our activities in a range of international locations, including North America (the United States and Mexico), South America (Peru, Chile and Uruguay), and EMEA (Spain, Algeria and South Africa), and we may expand our operations to certain core countries within these regions. Accordingly, we face a number of risks associated with operating and investing in different countries that may have a material adverse effect on our business, financial condition, results of operations and cash flows. These risks include, but are not limited to, adapting to the regulatory requirements of such countries, compliance with changes in laws and regulations applicable to foreign corporations, the uncertainty of judicial processes, and the absence, loss or non-renewal of favorable treaties, or similar agreements, with local authorities or political, social and economic instability, all of which can place disproportionate demands on our management, as well as significant demands on our operational and financial personnel and business. As a result, we can provide no assurance that our future international operations and investments will remain successful.

A significant portion of our current and potential future operations and investments are conducted in various emerging countries worldwide. Our activities and investments in these countries involve a number of risks that are more prevalent than in developed markets, such as economic and governmental instability, the possibility of significant amendments to, or changes in, the application of governmental regulations, the nationalization and expropriation of private property, payment collection difficulties, social problems, substantial fluctuations in interest and exchange rates, changes in the tax framework or the unpredictability of enforcement of contractual provisions, currency control measures, limits on the repatriation of funds and other unfavorable interventions or restrictions imposed by public authorities. In countries such as Algeria or South Africa, a change in government can cause instability in the country and a new government may decide to change laws and regulations affecting our assets or may decide to expropriate such assets, all of which may have a material adverse effect on our business, financial condition, results of operations and cash flows. Our U.S. dollar-denominated contracts in Algeria, Mexico, Chile and Peru are payable in local currency at the exchange rate of the payment date and in some cases include portions in local currency; our contract for Kaxu in South Africa is denominated and payable in South African rand. In the event of a rapid devaluation or implementation of exchange or currency controls, we may not be able to exchange the local currency for the agreed dollar amount, which could affect our cash available for distribution. Governments in Latin America and Africa frequently intervene in the economies of their respective countries and occasionally make significant changes in policy and regulations. Governmental actions in certain countries to control inflation and other policies and regulations have often involved, among other measures, price controls, currency devaluations, capital or exchange controls and limits on imports. Such devaluation, implementation of exchange or currency controls or governmental involvement may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Table of Contents

Decreases in government budgets, reductions in government subsidies and adverse changes in law may adversely affect our business and growth plan.

Poor economic conditions have affected, and continue to affect, government budgets and threaten the continuation of government subsidies such as regulated revenues, cash grants, tax benefits and other similar subsidies that benefit our business, particularly with respect to renewable energy. Such economic conditions may also lead to changes in laws that may be adverse to us. Policies supporting the development of renewable energy have had a significant effect on the growth of investments in renewable energy and could change at any time. Government subsidies and incentives make the development of renewable projects more competitive by providing tax credits and accelerated depreciation for a portion of the development costs, decreasing the costs associated with developing such projects or creating demand for renewable energy assets through RPS programs. A loss or reduction in such incentives could decrease the attractiveness of renewable energy projects to project developers and the attractiveness of renewable energy to utilities, which could reduce our acquisition opportunities. Such a loss or reduction could also reduce our willingness to pursue renewable energy projects due to higher operating costs or lower revenues. The reduction or elimination of subsidies or incentives or adverse changes in law could have a material adverse effect on our business, financial condition, results of operations and cash flows, inclusive of our existing projects, and the lack of availability of new projects undertaken in reliance on the continuation of such subsidies could adversely affect our growth plan.

Our cash dividend policy may limit our ability to grow and make acquisitions through cash on hand.

Our dividend policy is to distribute a high percentage of our cash available for distribution, after corporate general and administrative expenses and cash interest payments and less reserves for the prudent conduct of our business, each quarter and to rely primarily upon external financing sources, including the issuance of debt and equity securities as well as borrowings under credit facilities to fund our acquisitions and potential growth capital expenditures. We intend to distribute as dividend a high portion of the cash available for distribution that we generate on an annual basis, although our board of directors could modify that payout target in the future. We may be precluded from pursuing otherwise attractive acquisitions if the projected short-term cash flow from the acquisition or investment is not adequate to service the capital raised to fund the acquisition or investment, after giving effect to our available cash reserves.

On account of our dividend policy, our growth may not be as fast as that of businesses that reinvest their available cash to expand ongoing operations. To the extent we issue additional equity securities in connection with any acquisitions or growth capital expenditures, the payment of dividends on these additional equity securities may increase the risk that we will be unable to maintain or increase our per share dividend. There are no limitations in our articles of association on our ability to issue equity securities, including preference shares or other securities ranking senior to our shares. The issuance of additional debt securities and/or the incurrence of additional bank borrowings or other debt by us or by intermediate subsidiaries or by our project-level subsidiaries to finance our growth strategy could result in increased interest expense and the imposition of additional or more restrictive covenants, which, in turn, may impact the cash distributions we receive from our subsidiaries.

We may not be able to identify and reach agreements with new partners similar to the AAGES and Algonquin ROFO agreements.

We intend to enter into an agreement or agreements with new partners that own or develop renewable energy, electric transmission or water assets in the geographies in which we operate. Any such new partner would be a source of assets in addition to AAGES, Algonquin and Abengoa. We cannot be certain that we will be successful in identifying or reaching an agreement with new partners. We also cannot be certain that any agreement with a new partner will have terms similar to the AAGES ROFO Agreement and such terms may be less favorable to us. Even if we do reach an agreement with a new partner, it cannot be certain that we will be able to acquire assets from any such partner in the future.

Table of Contents

If we are unable to identify and reach an agreement on favorable terms with new partners with suitable assets, or unable to consummate future acquisitions from any such sponsor, it may limit our ability to execute our growth strategy and may have a materially adverse effect on our business, financial condition, results of operation and cash flows.

We may not be able to arrange the required or desired financing for acquisitions.

Our ability to effectively consummate future acquisitions will also depend on our ability to arrange the required or desired financing for acquisitions or to refinance existing corporate debt. We may not have access to the capital markets to issue new equity or debt securities or sufficient availability under our credit facilities or have access to project level financing on commercially reasonable terms when acquisition opportunities arise. During the second half of 2015 and first half of 2016, our access to financing was curtailed by market conditions and other factors. Starting the end of 2018 and continuing in the beginning of 2019, it has been a period of high volatility in capital markets, particularly in the United States and Europe. These adverse market conditions could prevent us from accessing the capital markets in a manner that would permit us to make an acquisition or refinancing the 2019 Notes in a timely manner.

An inability to obtain the required or desired financing could significantly limit our ability to consummate future acquisitions and effectuate our growth strategy. If financing is available, utilization of our credit facilities, debt securities or project level financing for all or a portion of the purchase price of an acquisition, as applicable, could significantly increase our interest expense, impose additional or more restrictive covenants, and reduce cash available for distribution. Similarly, the issuance of additional equity securities as consideration for acquisitions could cause significant shareholder dilution and reduce our per share cash available for distribution if the acquisitions are not sufficiently accretive. If we are unable to obtain financing necessary for acquisitions, it will impede our ability to execute our growth strategy and limit our ability to increase the amount of dividends paid to holders of our shares.

We may not be able to identify or consummate future acquisitions on favorable terms, or at all.

Our business strategy includes growth through the acquisition of additional revenue-generating assets. This strategy depends on our ability to successfully identify and evaluate acquisition opportunities and consummate acquisitions on favorable terms. However, the number of acquisition opportunities may be limited. We cannot be certain that AAGES, Algonquin or Abengoa will offer us assets under the ROFO agreements that fit within our portfolio of assets or contribute to our growth strategy. The Atacama project in Chile is currently owned by APW-1, an investment vehicle initially created by Abengoa as a joint venture with EIG and currently fully owned by EIG, an investment fund; although the Atacama project is subject to our ROFO agreement with APW-1, we cannot be certain that APW-1 will wish to sell the Atacama project at an attractive price or at all. See “Item 4.B—Business Overview—Our Business Strategy.”

Our ability to acquire future renewable energy projects or businesses depends on the viability of renewable energy projects generally. These projects currently are in many cases contingent on public policy mechanisms including, among others, ITCs, cash grants, loan guarantees, accelerated depreciation, expensing for certain capital expenditures, carbon trading plans, environmental tax credits and research and development incentives, as discussed in “Item 4.B—Regulation—Regulation in the United States—U.S. Federal Considerations for Renewable Energy Generation Facilities.” These mechanisms have been implemented at the U.S. federal and state levels and in certain other jurisdictions where our assets are located to support the development of renewable generation and other clean infrastructure technologies. The availability and continuation of public policy support mechanisms will drive a significant part of the economics and viability of our growth strategy and expansion into clean energy investments. See “—Government regulations providing incentives and subsidies for renewable energy could change at any time, including pursuant to the proposed environmental and tax policies of the current administration in the United States, and such changes may negatively impact our current business and our growth strategy.”

Table of Contents

Our ability to consummate future acquisitions may also depend on our ability to obtain any required government or regulatory approvals for such acquisitions, including, but not limited to, the Federal Energy Regulatory Commission, or FERC, approval under Section 203 of the FPA in respect of acquisitions in the United States; or any other approvals in the countries in which we may purchase assets in the future. We may also be required to seek authorizations, waivers or notifications from debt and/or equity financing providers at the project or holding company level; local or regional agencies or bodies; and/or development agencies or institutions that may have a contractual right to authorize a proposed acquisition.

Furthermore, we will compete with other companies for acquisition opportunities from third parties, which may increase our cost of making acquisitions or cause us to refrain from making acquisitions from third parties. Some of our competitors for acquisitions are much larger than us, with substantially greater resources. These companies may be able to pay more for acquisitions due to cost of capital advantages, synergy potential or other drivers, and may be able to identify, evaluate, bid for and purchase a greater number of assets than our financial or human resources permit. If we are unable to identify and consummate future acquisitions, it will impede our ability to execute our growth strategy and limit our ability to increase the amount of dividends paid to holders of our shares.

Our ability to consummate future acquisitions also depends on the availability of financing. See “—We may not be able to arrange the required or desired financing for acquisitions.”

Finally, demand for renewable energy may be affected by the cost of other energy sources, including nuclear, coal, natural gas and oil. For example, low natural gas prices have led, in some instances, to increased natural gas consumption in lieu of other energy sources. To the extent renewable energy becomes less cost-competitive cheaper alternatives or otherwise, demand for renewable energy could decrease. Slow growth or a long-term reduction in the energy demand could cause a reduction in the development of renewable energy programs projects. Decreases in the prices of electricity could affect our ability to acquire assets, as renewable energy developers may not be able to compete with providers of other energy sources at such lower prices. Our inability to acquire assets could have a material adverse effect on our ability to execute our growth strategy.

In order to grow our business, we may acquire assets or businesses which have a higher risk profile than certain assets in our current portfolio

In order to grow our business, we may acquire assets and businesses which may have a higher risk profile than certain of the assets we currently own. Competition to acquire contracted assets in operation has been high in recent years and is expected to continue being so. As a result, we have recently announced acquisitions with some exposure to development and construction risk. We may consider investing in assets which are not currently in operation and which are subject to development and construction risk. Construction of renewable assets, among others, is subject to risk of cost overruns and delays. There can be no assurances that assets under development and construction will perform as expected or that the returns will be as expected. In addition, we may consider acquiring business which are not contracted, including regulated businesses, which are subject to demand risk. We may also consider acquiring assets which are not contracted or not fully contracted, for which revenues will depend on the price of the electricity and which are subject to merchant risk. Furthermore, we may consider acquiring assets with revenues not denominated in US dollars or Euros, which would increase our exposure to local currency and which could generate higher volatility in the cash flows we generate. In all these type of assets and businesses, the risk of not meeting the expected cash flow generation and expected returns is higher than in contracted assets. In addition, these type of assets and businesses could present a higher variability in the cash flows they generate. As a result, the consummation of acquisitions may have a material adverse effect on our ability to grow, our business, financial condition, results of operations and cash flows.

We cannot guarantee the success of our recent and future acquisitions.

Acquisitions of companies and assets are subject to substantial risks, including the failure to identify material problems during due diligence (for which we may not be indemnified post-closing), the risk of over-paying for assets (or not making acquisitions on an accretive basis) and the ability to retain customers. Further, the integration and consolidation of acquisitions requires substantial human, financial and other resources and, ultimately, our acquisitions may divert management’s attention from our existing business concerns, disrupt our ongoing business or not be successfully integrated. There can be no assurances that any future acquisitions will perform as expected or that the returns will be as expected. As a result, the consummation of acquisitions may have a material adverse effect on our ability to grow, our business, financial condition, results of operations and cash flows.

We may be unable to complete all, or any, such transactions that we may contemplate. Even where we consummate acquisitions, we may be unable to achieve projected cash flows; recognize unexpected liabilities or costs; or encounter regulatory complications arising from such transactions. Furthermore, the terms and conditions of financing for such acquisitions or financial investments could restrict the manner in which we conduct our business. These risks could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We may not be able to close some of the acquisitions that we have recently announced. In some of these acquisitions, we have signed a share purchase agreement, but closing of the acquisition is subject to closing conditions and authorizations. For example, in the acquisition of PTS, we have acquired a 5% interest in the project and intend to increase our interest when the asset reaches COD and authorization from third parties. In the acquisition of Tenes, we have signed a share purchase agreement but closing is subject to the approval of Algerian authorities.

In addition, some of the transactions we have announced are acquisitions of assets under construction. Although our construction risk is limited, taking into account the nature of the assets and protection clauses in the share purchase agreements, there could be delays in construction and cost overruns not covered by the protection clauses in the relevant share purchase agreement, which may impede us to get to the expected CAFD in the assets we are acquiring.

We may also make acquisitions or investments in assets that are located in different jurisdictions and are different from, and may be riskier than, those jurisdictions in which we currently operate (the United States, Mexico, Peru, Chile, Uruguay, Spain, South Africa and Algeria). See “—We have international operations and investments, including in emerging markets that could be subject to economic, social and political uncertainties.” These changes may have a material adverse effect on our business, financial condition, results of operations and cash flows.

We are subject to extensive governmental regulation in a number of different jurisdictions, and our inability to comply with existing regulations or requirements or changes in applicable regulations or requirements may have a negative impact on our business, results of operations, financial condition or cash flows.

We are subject to extensive regulation of our business in the countries in which we operate. Such laws and regulations require licenses, permits and other approvals to be obtained in connection with the operations of our activities. This regulatory framework imposes significant actual, day-to-day compliance burdens, costs and risks on us. In particular, the power plants and transmission lines that we own are subject to strict international, national, state and local regulations relating to their operation and expansion (including, among other things, leasing and use of land, and corresponding building permits, landscape conservation, noise regulation, environmental protection and environmental permits and electric transmission and distribution network congestion regulations). Non-compliance with such regulations could result in the revocation of permits, sanctions, fines or even criminal penalties. Compliance with regulatory requirements may result in substantial costs to our operations that may not be recovered. In addition, we cannot predict the timing or form of any future regulatory or law enforcement initiatives. Changes in existing energy, environmental and administrative laws and regulations may have a material adverse effect on our business, financial condition, results of operations and cash flows, including on our growth plan and investment strategy. Our business may also be affected by additional taxes imposed on our activities, reduction of regulated tariffs and other cuts or measures.

Further, similar changes in laws and regulations could increase the size and number of claims and damages asserted against us or subject us to enforcement actions, fines and even criminal penalties. In addition, changes in laws and regulations may, in certain cases, have retroactive effect and may cause the result of operations to be lower than expected. In particular, our activities in the energy sector are subject to regulations applicable to the economic regime of generation of electricity from renewable sources and to subsidies or public support in the benefit of our production of energy from renewable energy sources, which vary by jurisdiction, and are subject to modifications that may be more restrictive or unfavorable to us.

Our business is subject to stringent environmental regulation.

We are subject to significant environmental regulation, which, among other things, requires us to obtain and maintain regulatory licenses, permits and other approvals and comply with the requirements of such licenses, permits and other approvals and perform environmental impact studies on changes to projects. In addition, our assets need to comply with strict environmental regulation on air emissions, water usage and contaminating spills, among others. As a company with most of the business in renewable energy, environmental incidents can also significantly harm our reputation. There can be no assurance that:

Table of Contents

public opposition will not result in delays, modifications to or cancellation of any project or license;

laws or regulations will not change or be interpreted in a manner that increases our costs of compliance and may have a material adverse effect on our business, financial condition, results of operations and cash flows, including preventing us from operating an asset if we are not in compliance; or

governmental authorities will approve our environmental impact studies where required to implement proposed changes to operational projects.

We believe that we are currently in material compliance with all applicable regulations, including those governing the environment. We have been found not to be in compliance with certain environmental regulations and have incurred fines and penalties associated with such violations which, to date, have not been material in amount. We can give no assurance, however, that we will continue to be in compliance or avoid material fines, penalties, sanctions and expenses associated with compliance issues in the future. Violation of such regulations may give rise to significant liability, including fines, damages, fees and expenses, and site closures. Generally, relevant governmental authorities are empowered to clean up and remediate releases of environmental damage and to charge the costs of such remediation and clean-up to the owners or occupiers of the property, the persons responsible for the release and environmental damage, the producer of the contaminant and other parties, or to direct the responsible parties to take such action. These governmental authorities may also impose a tax or other liens on the responsible parties to secure the parties’ reimbursement obligations.

Environmental regulation has changed rapidly in recent years, and it is possible that we will be subject to even more stringent environmental standards in the future, including in relation to climate change. We cannot predict the amounts of any increased capital expenditures or any increases in operating costs or other expenses that we may incur to comply with applicable environmental, or other regulatory, requirements, or whether these costs can be passed on to its concession contract counterparties through price increases. The costs of compliance as well as non-compliance may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Increases in the cost of energy and gas could increase our operating costs in some of our assets.

Some of our activities require some consumption of energy and gas, and we are vulnerable to material fluctuations in their prices. For example, our Spanish solar assets produce a small percentage of their electricity using natural gas. Although our energy and gas purchase contracts generally include indexing mechanisms, we cannot guarantee that these mechanisms will cover all of the additional costs generated by an increase in energy and gas prices, particularly for long-term contracts, and some of the contracts entered into by us do not include any indexing provisions. Significant increases in the cost of energy or gas, or shortages of the supply of energy and/or gas, may have a materially adverse effect on our business, financial condition, results of operations and cash flows.

Transactions with counterparties expose us to credit risk which we must effectively manage to mitigate the effect of counterparty default.

We are exposed to the credit risk profile of the counterparties to our long-term concession contracts, our suppliers and our financing providers. Although we actively manage this credit risk through diversification and other measures, our risk management strategy may not be successful in limiting our exposure to credit risk. Our inability to manage this exposure may have a material adverse effect on our business, financial condition, results of operations and cash flow.

We may be subject to increased finance expenses if we do not effectively manage our exposure to interest rate and foreign currency exchange rate risks.

We are exposed to various types of market risk in the normal course of business, including the impact of interest rate changes and foreign currency exchange rate fluctuations. Some of our indebtedness (including project-level indebtedness) bears interest at variable rates, generally linked to market benchmarks such as EURIBOR and U.S. LIBOR. Any increase in interest rates would increase our finance expenses relating to our variable rate indebtedness and increase the costs of refinancing our existing indebtedness and issuing new debt.

Table of Contents

In addition, although most of our long-term contracts are denominated in, indexed or hedged to U.S. dollars, we conduct our business and incur certain costs in the local currency of the countries in which we operate. In addition, the revenues, costs and debt of our solar assets in Spain are denominated in euros. Since the beginning of 2017, we have maintained euro-denominated debt at the corporate level. Interest payments in euros and our euro denominated general and administrative expenses create a natural hedge for a portion of the distributions from Spanish assets. Our strategy is to hedge the exchange rate for the distributions from our Spanish assets after deducting euro-denominated interest payments and euro-denominated general and administrative expenses. Through currency options, we hedge 100% of the net euro net exposure for the next 12 months and 75% of the net euro net exposure for the following 12 months. See “Item 5.A—Operating and Financial Review—Results of Operations—Factors Affecting our Results of Operations.”

As we continue expanding our business, an increasing percentage of our revenue and cost of sales may be denominated in currencies other than our reporting currency, the U.S. dollar. Under that scenario, we would become subject to increasing currency exchange risk, whereby changes in exchange rates between the U.S. dollar and the other currencies in which we do business could result in foreign exchange losses.

In addition, we seek to actively work with lending financial institutions to mitigate our interest rate risk exposure and to secure lower interest rates by entering into interest rate options and swaps. As a matter of policy, we seek to cover at least 70% of our outstanding long-term project debt interest rate risk.

If our risk-management strategies are not successful in limiting our exposure to changes in interest rates and foreign currency exchange rates our business, financial condition, results of operations and cash flows maybe materially adversely affected.

Uncertainty relating to the LIBOR calculation process and potential phasing out of LIBOR in the future may adversely affect the value of any outstanding debt instruments.

National and international regulators and law enforcement agencies have conducted investigations into a number of rates or indices known as “reference rates.” Actions by such regulators and law enforcement agencies may result in changes to the manner in which certain reference rates are determined, their discontinuance, or the establishment of alternative reference rates. In particular, on July 27, 2017, the Chief Executive of the U.K. Financial Conduct Authority (the “FCA”), which regulates LIBOR, announced that the FCA will no longer persuade or compel banks to submit rates for the calculation of LIBOR after 2021. Such announcement indicates that the continuation of LIBOR on the current basis cannot and will not be guaranteed after 2021. As a result, it appears highly likely that LIBOR will be discontinued or modified by 2021.

At this time, it is not possible to predict the effect that these developments, any discontinuance, modification or other reforms to LIBOR or any other reference rate, or the establishment of alternative reference rates may have on LIBOR, other benchmarks, or LIBOR-based debt instruments. Uncertainty as to the nature of such potential discontinuance, modification, alternative reference rates or other reforms may materially adversely affect the trading market for securities linked to such benchmarks. Furthermore, the use of alternative reference rates or other reforms could cause the interest rate calculated for the LIBOR-based debt instruments to be materially different than expected.

Our competitive position could be adversely affected by changes in technology, prices, industry standards and other factors.

The markets in which our assets or projects operate change rapidly because of technological innovations and changes in prices, industry standards, product instructions, customer requirements and the economic environment. New technology or changes in industry and customer requirements may put pressure on the profitability of our existing projects by increasing the incentives of counterparties to our long-term contracts to seek new alternative projects or request higher service standards.

The performance of our assets under our concession contracts may be adversely affected by problems related to our reliance on third-party contractors and suppliers.

Our projects rely on the supply of services, equipment, including technologically complex equipment and software which we subcontract to Abengoa and other third-party suppliers in order to meet our contractual obligations under our contracted concessions. We rely on the equipment, design and technology of third parties to operate our assets. In circumstances where key components of our equipment, including but not limited to turbines, water pumps or transformers, fail because of design failures or faulty operation or for any other reason, we rely on third parties to continue operating our assets. Equipment may not last as long as expected and may be need to be replaced earlier than planned. Damages to our equipment may not be covered by insurance in place. In some cases, the replacement of damaged equipment can take a long period of time, which can cause our plants to curtail or cease operations during such time, which could have a negative impact on our business, financial condition, results of operations and cash flows. We had significant interruptions in 2017 at Kaxu as a result of water pump failures and at Solana in 2017 as a result of transformer failures. In addition, Solana has experienced technical issues in the heat exchangers within its storage system. Repairs have been carried out. In 2018, Abengoa and the supplier of the heat exchangers presented a proposal to improve the performance and reliability of this equipment which has been implemented progressively in 2018. We plan to replace one of the heat exchangers in 2019. In addition, we are currently purchasing an additional heat exchanger which is expected to be kept as a backup in case the others failed. Furthermore, in the last quarter of 2017 and the first quarter of 2018, we had temporary unavailability at some of our plants due to technical inspections of the turbines that were requested by the supplier of the turbines. Similar interruptions could happen again at Kaxu or Solana or at other plants due to failures in key equipment. Design failures, technical inspections by suppliers or the need to replace key equipment can require unexpected capital expenditures and/or outages in our plants, which may have a material adverse effect on our business, results of operations, financial condition and cash flows.

In addition, the delivery of products or services which are not in compliance with the requirements of the subcontract, or the late supply of products and services, can cause us to be in default under our contracts with our concession counterparties. To the extent we are not able to transfer all of the risk or be fully indemnified by Abengoa or other third-party contractors and suppliers, we may be subject to a claim by our customers as a result of a problem caused by a third party that could have a material adverse effect on our reputation, business, results of operations, financial condition and cash flows.

Supplier concentration may expose us to significant financial credit or performance risk.

We often rely on a single contracted supplier or a small number of suppliers for the provision of equipment, technology, fuel, transportation of fuel, and/or other services required for the operation of certain of our facilities. If any of these suppliers, including Abengoa and its subsidiaries, cannot perform under their operation and maintenance and other agreements with us, or satisfy their related warranty obligations, we will need to access the marketplace to provide or repair these products and services. There can be no assurance that the marketplace can provide these products and services as, when and where required. We may not be able to enter into replacement agreements on favorable terms or at all. If we are unable to enter into replacement agreements to provide for equipment, technology or fuel and other required services, we may be required to seek to purchase the related goods or services at market prices, exposing us to the risk of unavailability and market price volatility. We may also be required to make significant capital contributions to remove, replace or redesign equipment that cannot be supported or maintained by replacement suppliers, which may have a material adverse effect on our business, financial condition, results of operations, credit support terms and cash flows.

The failure of any supplier or customer to fulfill its contractual obligations to us may have a material adverse effect on our business, financial condition, results of operations and cash flows. Consequently, the financial performance of our facilities is dependent on the credit quality of, and continued performance by, our suppliers and vendors.

Table of Contents

We may have joint venture partners or other co-investors with whom we have material disagreements.

We have made and may continue to make equity investments in certain strategic assets managed by or together with third parties, including governmental entities and private entities. In certain cases, we may only have partial or joint control over a particular asset. We hold a minority stake in Honaine (Algeria), PTS (Mexico) and Ten West Link (United States) and do not have control over the operation of these assets. In addition, we have partners in Solacor 1/2, Solaben 2/3, Skikda, Kaxu and Solana, and if we close the acquisition of Tenes, we would have partners in that asset as well. Investments in assets over which we have no, partial or joint control are subject to the risk that the other shareholders of the assets, who may have different business or investment strategies than us or with whom we may have a disagreement or dispute, may have the ability to independently make or block business, financial or management decisions, such as appoint members of management, which may be crucial to the success of the project or our investment in the project, or otherwise implement initiatives which may be contrary to our interests. Additionally, the approval of other shareholders or partners may be required to sell, pledge, transfer, assign or otherwise convey our interest in such assets. Similarly, the approval of other shareholders or partners may be required to acquire AAGES’, Algonquin’s, Abengoa’s or third parties’ interests in potential acquisitions. Alternatively, other shareholders may have rights of first refusal or rights of first offer in the event of a proposed sale or transfer of our interests in such assets or in the event of our acquisition of an interest in new assets pursuant to the ROFO agreements or with third parties. These restrictions may limit the price or interest level for our interests in such assets, in the event we want to sell such interests.

Finally, our partners in existing or future projects, including tax equity investors, may be unable, or unwilling, to fulfill their obligations under the relevant shareholder agreements, may experience financial or other difficulties or might sell their position to third parties that we did not choose, which may adversely affect our investment in a particular joint venture or adversely affect us. In certain of our joint ventures, we may also be reliant on the particular expertise of our partners and, as a result, any failure to perform its obligations in a diligent manner could also adversely affect the joint venture. If any of the foregoing were to occur, our business, financial condition, results of operations and cash flows may be materially adversely affected.

Our failure to maintain safe work environments may expose us to significant financial losses, as well as civil and criminal liabilities.

The facilities we operate often put our employees and others, including those of our subcontractors, in close proximity with large pieces of mechanized equipment, moving vehicles, manufacturing or industrial processes, heat or liquids stored under pressure and highly regulated materials. On most projects and at most facilities, we, together with the operations and maintenance supplier, are responsible for safety and, accordingly, must implement safe practices and safety procedures, which are also applicable to on-site subcontractors. If we or the operations and maintenance supplier fail to design and implement such practices and procedures or if the practices and procedures are ineffective or if our operations and maintenance service providers or other suppliers do not follow them, our employees and others may become injured and our and others’ property may become damaged. Unsafe work sites also have the potential to increase employee turnover, increase the cost of a project to our customers or the operation of a facility, and raise our operating costs. Any of the foregoing could result in financial losses, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

In addition, our projects and the operation of our facilities can involve the handling of hazardous and other highly regulated materials, which, if improperly handled or disposed of, could subject us or our suppliers to civil and criminal liabilities. We are also subject to regulations dealing with occupational health and safety. Although we maintain divisions whose primary purpose is to ensure we implement effective health, safety and environmental work procedures throughout our organization, the failure to comply with such regulations could subject us to liability. In addition, we may incur liability based on allegations of illness or disease resulting from exposure of employees or other persons to hazardous materials that we handle or are present in our workplaces.

The operation and maintenance of most of our assets is labor intensive, and therefore work stoppages by employees could harm our business.

The operation and maintenance of most of our assets is labor intensive and our operators’ employees are covered by collective bargaining agreements. A dispute with a union or employees represented by a union could result in production interruptions caused by work stoppages. In addition, we subcontract the operation and maintenance services in most of our assets. Abengoa is the operation and maintenance supplier in most of our assets and Abengoa’s financial situation could cause a higher risk of dispute with their employees. If our operators’ employees were to initiate a work stoppage, they may not be able to reach an agreement with them as fast as in the case where we were negotiation with our own employees. If a strike or work stoppage were to occur, our business, financial conditions, results of operations and cash flows may be materially adversely affected.

Our business may be adversely affected by an increased number of extreme weather events related to climate change.

Climate change is causing an increasing number of severe and extreme weather events which are a risk to our facilities, including days of extremely high temperatures, severe winds and rains, hurricanes, droughts, fires, cyclones and floods, among others. Other risks include:

Rising temperatures are also increasing the frequency and intensity of droughts and risk of fire. For example, in California, the size and ferocity of fires has increased significantly in the past 20 years, which have also been very hot and dry years. California wildfires have been especially catastrophic, causing human fatalities and significant material losses. Our transmission lines, including transmission lines and substations which are part of our solar assets, could cause fires, which can create significant liabilities if the fire damaged third parties.

Severe floods could damage our plants, especially our transmission lines or our generation assets. If an unexpected flood runs close to an existing transmission tower it could cause the fall of one or more transmission towers. Similarly, a flood can damage the solar field in our solar plants.

Severe winds could cause damage in the solar fields in our solar assets. In 2016, the solar field of Solana was damaged by a wind micro-burst and similar events could happen in the future in our assets.

Severe droughts could result in water restrictions or in a deterioration of water properties. Droughts may affect the cooling capacity of our power projects. A deterioration of the quality of the water would have an impact on chemical costs in our water treatment plants within our generation capabilities.

Changes in temperature extremes could also affect to feed water process temperature in desalination plants, causing an increase of the chemical products consumption and generating a risk of growth of algae and mollusks within the facilities.

Storms with intense lightning activity could damage our plants, especially our wind assets. Our wind farms in Uruguay have already experienced some damages in the past and our assets could be affected again.

It is extremely difficult to assess the economic financial impact this may have. All these events could cause a material adverse effect in our business, results of operations and cash flows.

Our business may be adversely affected by rising mean temperatures caused by climate change.

In addition, to the physical risks previously mentioned, rising temperatures could cause an increase in our operation and maintenance costs. Rising temperatures are associated to the reduction of the cycle efficiency of our turbines. A temperature rise would also be associated to a reduction of efficiency in solar photovoltaic modules. Modules efficiency is reduced above a certain temperature threshold. When the temperature of the solar panel increases, its output current slightly increases while the voltage output is reduced linearly therefore panel power decreases. A mean temperature rise would also have an impact in our wind facilities. Wind energy component is dependent on the air density among other factors. Our desalination plants could also be affected by a temperature increase that would imply higher consumption of chemicals used for operational purposes. This could cause a material adverse effect in our business, results of operations and cash flows.

Our business may be adversely affected by catastrophes, natural disasters, unexpected geological or other physical conditions, or criminal or terrorist acts at one or more of our plants, facilities and electric transmission lines.

If one or more of our plants, facilities or electric transmission lines were to be subject in the future to fire, flood, extreme weather conditions (including severe wind), earthquakes or other natural disaster, adverse weather conditions, drought, terrorism, power loss or other catastrophe, or if unexpected geological or other adverse physical conditions (including earthquakes) were to occur at any of our plants, facilities or electric transmission lines, we may not be able to carry out our business activities at that location or such operations could be significantly reduced. Any of these circumstances could result in lost revenue at these sites during the period of disruption and costly remediation, which could have a material adverse effect on our business, financial condition, results of operations and cash flows. In addition, it is possible that our sites and assets could be affected by criminal or terrorist acts. There are also certain risks for which we may not be able to acquire adequate insurance coverage, including earthquakes. Any such events could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our insurance may be insufficient to cover relevant risks or the cost of our insurance may increase .

We cannot guarantee that our insurance coverage is, or will be, sufficient to cover all of the possible losses we may face in the future. If we were to incur a serious uninsured loss or a loss that significantly exceeded the coverage limits established in our insurance policies, the resulting costs could have a material adverse effect on our business, financial condition, results of operations and cash flows.

In addition, our insurance policies are subject to review by our insurers. We may not be able to renew or insurance policies in the terms required by our power purchase agreements and project financing agreements, which could require a waiver from those parties. If insurance premiums were to increase in the future, if certain types of insurance coverage were to become unavailable or there was an increase in deductibles for damages and/or loss of production, it could have an adverse effect on our ability to comply with our obligations to the lenders in our project finance agreements. In addition, we might not be able to maintain insurance coverage comparable to those that are currently in effect at comparable cost, or at all. If we were unable to pass any increase in insurance premiums on to our customers, such additional costs could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We may be subject to litigation and other legal proceedings.

We are subject to the risk of legal claims and proceedings (including bankruptcy), requests for arbitration as well as regulatory enforcement actions in the ordinary course of our business and otherwise, including claims against our subsidiaries related to Abengoa or our subsidiaries not meeting their obligations. See “Item 4.B—Business Overview—Legal Proceedings.” The results of legal and regulatory proceedings cannot be predicted with certainty. We cannot guarantee that the results of current or future legal or regulatory proceedings or actions will not materially harm our business, financial condition, results of operations or operations, nor can we guarantee that we will not incur losses in connection with current or future legal or regulatory proceedings or actions that exceed any provisions we may have set aside in respect of such proceedings or actions or that exceed any available insurance coverage, which may have a material adverse effect on our business, financial condition, results of operations and cash flows. See “Item 4.B—Business Overview—Legal Proceedings.”

We are subject to reputational risk, and our reputation is closely related to that of Algonquin and Abengoa.

We rely on our reputation to do business, obtain financing, hire and retain employees and attract investors, one or more of which could be adversely affected if our reputation were damaged. Harm to our reputation could arise from real or perceived faulty or obsolete technology, failure to comply with legal and regulatory requirements, difficulties in meeting contractual obligations or standards of quality and service, ethical issues, money laundering and insolvency, among others.

Algonquin is currently our largest shareholder. Our reputation is affected by Algonquin’s reputation. If the public image or reputation of Algonquin were to be damaged as a result of adverse publicity, poor financial or operating performance, changes in financial condition, decline in the price of its shares or otherwise, we could be adversely affected, which could have a material adverse effect on our business, financial condition and results of operations and cash flows.

In addition, our reputation remains affected by Abengoa’s reputation, given Abengoa was until recently our largest shareholder and is currently our largest supplier. The public image and reputation of Abengoa have suffered as a result of its financial condition and its restructuring process. We have been adversely affected due to our relationship with Abengoa. Any further developments with respect to Abengoa’s financial condition or operating performance or any failure by Abengoa to satisfactorily resolve the proceedings discussed below could further harm our reputation, which could have an adverse effect on our business, financial condition and results of operations and cash flows. See “—Risks Related to Our Relationship with Algonquin and Abengoa.”

The loss of one or more of our executive officers or key employees may adversely affect our ability to effectively manage our projects.

We depend on our experienced management team and the loss of one or more key executives may negatively affect our business. We also depend on our ability to retain and motivate key employees and attract qualified new employees. We may not be able to replace departing members of our management team or key employees. Integrating new executives into our management team and training new employees with no prior experience in our industry could prove disruptive to our projects, require a disproportionate amount of resources and management attention and ultimately prove unsuccessful. An inability to attract and retain sufficient technical and managerial personnel could limit our ability to effectively manage our projects, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We use information technology and communications systems to run our business, the failure of which could significantly impact our operations and business.

We are dependent upon information technology systems in the conduct of our operations. Our information technology systems are subject to disruption, damage or failure from a variety of sources, including, without limitation, computer viruses, security breaches, cyber-attacks, phishing attacks, natural disasters and defects in design. Recently, energy facilities have been experiencing an increased number of cyber-attacks. Cybersecurity incidents, in particular, are constantly evolving and include malicious software, attempts to gain unauthorized access to data and other electronic security breaches that could lead to disruptions in systems, unauthorized release of confidential or otherwise protected information and the corruption of data. Various measures have been implemented to minimize our risks related to information technology systems and network disruptions. However, given the unpredictability of the timing, nature and scope of information technology disruptions, we could potentially be subject to production downtimes, operational delays, the compromising of confidential or otherwise protected information, destruction or corruption of data, security breaches, other manipulation or improper use of our systems and networks or financial losses from remedial actions, any of which could have a material adverse effect on our competitive position, financial condition, results of operations or cash flows.

We maintain global information technology and communication networks and applications to support our business activities. Information technology security processes may not prevent future malicious actions, denial-of-service attacks, or fraud, resulting in corruption of operating systems, theft of commercially sensitive data, misappropriation of funds and business (also known as phishing) and operational disruption. Material system breaches and failures could result in significant interruptions that could in turn affect our operating results and reputation.

Harming of protected species or other environmental hazards can result in curtailment of power plant operations, monetary fines and negative publicity.

The operation of wind and solar power plants can adversely affect endangered, threatened or otherwise protected animal species. Wind power plants involve a risk that protected species will be harmed, as the turbine blades travel at a high rate of speed and may strike flying animals (such as birds or bats) that happen to travel into the path of spinning blades. Solar power plants can also present a risk to animals.

Excessive taking of protected species or other environmental accidents or hazards could result in requirements to implement mitigation strategies, including curtailment of operations, and/or substantial monetary fines and negative publicity. We cannot guarantee that any curtailment of operations, monetary fines that are levied or negative publicity that we receive as a result of incidental taking of protected species and other environmental hazards will not have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our international operations require us to comply with anti-corruption and other laws and regulations of the United States government and various non-U.S. jurisdictions.

Doing business in multiple countries requires us and our subsidiaries to comply with the laws and regulations of the United States government and various non-U.S. jurisdictions. Our failure to comply with these rules and regulations may expose us to liabilities. These laws and regulations may apply to us, our subsidiaries, individual directors, officers, employees and agents, and may restrict our operations, trade practices, investment decisions and partnering activities.

Table of Contents

In particular, our non-U.S. operations are subject to United States and foreign anti-corruption laws and regulations, such as the Foreign Corrupt Practices Act of 1977, as amended (“FCPA”), and similar laws and regulations. The FCPA prohibits United States companies and their officers, directors, employees and agents acting on their behalf from corruptly offering, promising, authorizing or providing anything of value to foreign officials for the purposes of influencing official decisions or obtaining or retaining business or otherwise obtaining favorable treatment. The FCPA also requires companies to make and keep books, records and accounts that accurately and fairly reflect transactions and dispositions of assets and to maintain a system of adequate internal accounting controls. As part of our business, we deal with state-owned business enterprises, the employees and representatives of which may be considered foreign officials for purposes of the FCPA. As a result, business dealings between our employees and any such foreign official could expose us to the risk of violating anti-corruption laws even if such business practices may be customary or are not otherwise prohibited between the us and a private third party. Violations of these legal requirements are punishable by criminal fines and imprisonment, civil penalties, disgorgement of profits, injunctions, debarment from government contracts as well as other remedial measures.

We have established policies and procedures designed to assist us and our personnel in complying with applicable United States and non-U.S. laws and regulations; however, we cannot assure you that these policies and procedures will completely eliminate the risk of a violation of these legal requirements, and any such violation (inadvertent or otherwise) could have a material adverse effect on our business, financial condition and results of operations and cash flows.

The seasonality of our operations may affect our liquidity.

We will need to maintain sufficient financial liquidity at the asset level to absorb the impact of seasonal variations in energy production or other significant events. In our assets, the principal source of liquidity is cash generated from our operating activities and the principal use of liquidity consists of project debt service. Our quarterly results of operations may fluctuate significantly for various reasons, mostly related to weather patterns.

For instance, the amount of electricity and revenues generated by our solar generation facilities is dependent in part on the amount of solar radiation. The electricity produced and revenues generated by a wind power plant depend heavily on wind conditions, which are variable and difficult to predict. Operating results for wind power plants vary significantly from period to period depending on the wind conditions during the periods in question. We expect our portfolio of renewable energy facilities to generate the lowest amount of electricity during the first and fourth quarters.

The seasonality of our energy production may create increased demand on our working capital reserves during periods where cash generated from operating activities is lower, which could result in lower distributions from assets to the holding company level, in which event our financial condition may be materially adversely affected.

If we are deemed to be an investment company, we may be required to institute burdensome compliance requirements and our activities may be restricted, which may make it difficult for us to complete strategic acquisitions or effect combinations.

If we were deemed to be an investment company under the Investment Company Act of 1940 (the “Investment Company Act”) our business would be subject to applicable restrictions under the Investment Company Act, which could make it impractical for us to continue our business as contemplated. We believe our company is not an investment company under Section 3(b)(1) of the Investment Company Act because we are primarily engaged in a noninvestment company business, and we intend to conduct our operations so that we will not be deemed an investment company. However, if we were to be deemed an investment company, restrictions imposed by the Investment Company Act, including limitations on our capital structure and our ability to transact with affiliates, could make it impractical for us to continue our business as contemplated.

Risks Related to Our Assets

The concession agreements or power purchase agreements under which we conduct some of our operations are subject to revocation or termination.

Certain of our operations are conducted pursuant to contracts and concessions granted by various governmental bodies and others are pursuant to power purchase agreements signed with governmental entities and private clients. Generally, these contracts and concessions give us rights to provide services for a limited period of time, subject to various governmental regulations. The governmental bodies or private clients responsible for regulating and monitoring these services often have broad powers to monitor our compliance with the applicable concession and power purchase contracts and can require us to supply them with technical, administrative and financial information. Among other obligations, we may be required to comply with operating targets and efficiency and safety standards established in the concession. Such commitments and standards may be amended in certain cases by the governmental bodies. Our failure to comply with the concession agreements and power purchase agreements or other regulatory requirements may result in contracts and concessions being revoked, not being granted, upheld or renewed in our favor, or, if granted, upheld or renewed, may not be done on as favorable terms as currently applicable. This could have a material adverse effect on our business, financial condition, results of operations and cash flows.

In some of the markets in which we are present, or in which we may own assets in the future, political instability, economic crisis or social unrest may give rise to a change in policies regarding long-term contracted assets with private companies, like us, in strategic sectors such as power generation, electric transmission or water. Any such changes could lead to modifications of the economic terms of our concession contracts or, in extreme scenarios, the nationalization of our assets, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Revenues in our solar assets in Spain are mainly defined by regulation and some of the parameters defining the remuneration are subject to review every six years.

In 2013, the Spanish government modified regulations applicable to renewable energy assets, including solar power. According to Royal Decree 413/2014, solar electricity producers in Spain receive: (i) the pool price for the power they produce and (ii) a payment based on the standard investment cost for each type of plant (without any relation whatsoever to the amount of power they generate). This payment based on investment (in €/MW of installed capacity) is supplemented, in the case of solar plants, by an “operating payment” (in €/MWh produced).

The principle driving this economic regime is that the payments received by a renewable energy producer should be equivalent to the costs that they are unable to recover on the electricity pool market where they compete with non-renewable technologies. This economic regime seeks to allow a “well-run and efficient enterprise” to recover the costs of building and running a plant, plus a reasonable return on investment (project investment rate of return). This reasonable return is currently calculated as the average yield on Spanish government 10-year bonds on the secondary market in a 24-month period preceding the new regulatory period, plus a spread depending on the government’s decision based on the following indicative criteria:

Appropriate profit for this specific type of renewable electricity generation and electricity generation as a whole, considering the financial condition of the Spanish electricity system and Spanish prevailing economic conditions; and

Borrowing costs for electricity generation companies using renewable energy sources with regulated payment systems, which are efficient and well run, within Europe.

Payment criteria are based on prevailing economic conditions in Spain, demand for electricity and reasonable profits for electricity generation activities and can be revised every six years at the end of each regulatory period. The first regulatory period commenced on July 14, 2013, the date on which Royal Decree-law 9/2013 came into force and will end on December 31, 2019. The values of parameters used to calculate the payments can be changed at the end of each regulatory period, except for a plant’s useful life and the value of a plant’s initial investment.

If the payments for renewable energy plants are revised to lower amounts in the next regulatory period starting on January 1, 2020 until December 31, 2025, this could have a material adverse effect on our business, financial condition, results of operations and cash flows. As a reference, assuming our Spanish assets continue to perform as expected and assuming no additional changes of circumstances, with the information currently available, Atlantica estimates that a reduction of 100 basis points in the reasonable rate of return on investment set by the Spanish government could cause a reduction in its cash available for distribution of approximately €18 million per year. This estimate is subject to certain assumptions, which may change in the future.

Our solar assets in Spain receive revenues under a regulation based on a reasonable rate of returns which is subject to review every six years, with the first regulatory period ending at the end of 2019. On July 27, 2018, CNMC (the regulator for the electric system in Spain) issued a draft proposal for the calculation of the reasonable rate of return for the regulatory period 2020-2025. The draft reasonable rate of return proposed by CNMC was 7.04%. On November 2, 2018, CNMC issued its final report with a proposed reasonable rate of return of 7.09%. In December 2018 the government issued a draft project law proposing a reasonable rate of return of 7.09%. This draft also contemplates the possibility of maintaining the current reasonable rate of return for certain assets under certain circumstances for two consecutive regulatory periods. This draft is non-binding, open to comments and would have to be approved by the Spanish parliament. In addition, since elections are scheduled to take place in April in Spain, the draft may not be approved.

A reduction in the remuneration of our Spanish solar assets would have a negative impact on our business, financial condition, results of operations and cash flows.

Revenue from our contracted assets and concessions is significantly dependent on regulated tariffs or other long-term fixed rate arrangements that restrict our ability to increase revenue from these operations.

The revenue that we generate from our contracted assets and concessions is significantly dependent on regulated tariffs or other long-term fixed rate arrangements. Under most of our concession agreements, a tariff structure is established upon execution of such agreements, and we have limited or no possibility to independently raise tariffs beyond the established rates and indexation or adjustment mechanisms. Similarly, under a long-term PPA, we are required to deliver power at a fixed rate for the contract period or to maintain our asset available for a fixed rate, in some cases with predefined escalation rights. In addition, we may be unable to adjust our tariffs or rates as a result of fluctuations in prices of raw materials, exchange rates, labor and subcontractor costs during the operating phase of these projects, or any other variations in the conditions of specific jurisdictions in which our concession-type infrastructure projects are located, which may reduce our profitability. Moreover, in some cases, if we fail to comply with certain pre-established conditions, the government or customer (as applicable) may reduce the tariffs or rates payable to us. In addition, during the life of a concession, the relevant government authority may in some cases unilaterally impose additional restrictions on our tariff rates, subject to the regulatory frameworks applicable in each jurisdiction. In some cases, governments may also postpone annual tariff increases until a new tariff structure is approved without compensating us for lost revenue. Furthermore, changes in laws and regulations may, in certain cases, have retroactive effect and expose us to additional compliance costs or interfere with our existing financial and business planning.

Revenue from our renewable energy and efficient natural gas facilities is partially exposed to market electricity prices.

Revenue and operating costs from certain of our existing or future projects depend to some extent on market prices for sales of electricity. Market prices may be volatile and are affected by various factors, including the cost of raw materials, user demand, and if applicable, the price of greenhouse gas emission rights. In several of the jurisdictions in which we operate, we are exposed to remuneration schemes which contain both regulated incentive and market price components. In such jurisdictions, the regulated incentive component may not compensate for fluctuations in the market price component, and, consequently, total remuneration may be volatile. There can be no assurance that market prices will remain at levels which enable us to maintain profit margins and desired rates of return on investment. A decline in market prices below anticipated levels could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our renewable energy projects will be negatively affected if there are adverse changes to national and international laws and policies that support renewable energy sources.

Certain countries, such as the United States, a market that is one of our principal markets, have in recent years enacted policies of active support for renewable energy. These policies have included feed-in tariffs and renewable energy purchase obligations, mandatory quotas and/or portfolio standards imposed on utilities and certain tax incentives (such as ITCs in the United States).

Certain policies currently in place may expire, be suspended or be phased out over time, cease upon exhaustion of the allocated funding or be subject to cancellation or non-renewal, particularly if the cost of renewable energy exceeds the cost of generation of energy from other means. Accordingly, we cannot guarantee that such government support will be maintained in full, in part or at all.

Table of Contents

If the governments and regulatory authorities in the jurisdictions in which we operate or plan to operate were to further decrease or abandon their support for development of renewable energy due to, for example, competing funding priorities, political considerations or a desire to favor other energy sources, renewable or otherwise, the assets we plan to acquire in the future could become less profitable or cease to be economically viable. Such an outcome could have a material adverse effect on our ability to execute our growth strategy.

Lack of electric transmission capacity availability, potential upgrade costs to the electric transmission grid, and other systems constraints could significantly impact our ability to generate electricity power sales.

We depend on electric interconnection and transmission facilities owned and operated by others to deliver the wholesale power we sell from our electric generation assets to our customers. A failure or delay in the operation or development of these interconnection or transmission facilities or a significant increase in the cost of the development of such facilities could result in the loss of revenues. Such failures or delays could limit the amount of power our operating facilities deliver or delay the completion of our construction projects, as the case may be. Additionally, such failures, delays or increased costs may have a material adverse effect on our business, financial condition, results of operations and cash flows. If a region’s electric transmission infrastructure is inadequate, our ability to generate electricity may be limited. If restrictive transmission price regulation is imposed, the transmission companies may not have a sufficient incentive to invest in expansion of transmission infrastructure. We cannot predict whether interconnection and transmission facilities will be expanded in specific markets to accommodate competitive access to those markets. Certain of our operating facilities’ generation of electricity may be curtailed without compensation due to transmission limitations or limitations on the electricity grid’s ability to accommodate intermittent electricity generating sources, reducing our revenues and impairing our ability to capitalize fully on a particular facility’s generating potential. Such curtailments may have a material adverse effect on our business, financial condition, results of operations and cash flows.

We do not own all of the land on which our renewable energy, efficient natural gas or electric transmission assets are located, which could result in disruption to our operations.

We do not own all of the land on which our power generation or electric transmission assets are located, and we are, therefore, subject to the possibility of less desirable terms and increased costs to retain necessary land use if we do not have valid leases or rights-of-way or if such rights-of-way lapse or terminate or if the owners of the land enter into bankruptcy protection or seek to terminate contracts in some other way. Although we have obtained rights to construct and operate these assets pursuant to related lease arrangements, our rights to conduct those activities are subject to certain exceptions, including the term of the lease arrangement. Our loss of these rights, through our inability to renew right-of-way contracts or otherwise, may adversely affect our ability to operate our power generation and electric transmission assets and may therefore have a material adverse effect on our business, financial condition, results of operation and cash flow.

Certain of our facilities may not perform as expected.

Our expectations regarding the operating performance of certain assets, particularly Solana and Kaxu, assets recently acquired and assets for which acquisition has recently been announced, are based on assumptions, estimates and past experience, and without the benefit of a substantial operating history. Our projections regarding our ability to generate cash available for distribution assumes facilities perform in accordance to our expectations. However, the ability of these facilities to meet our performance expectations is subject to the risks inherent in power generation facilities and the construction of such facilities, including, but not limited to, degradation of equipment in excess of our expectations, system failures and outages. The failure of these facilities to perform as we expect may have a material adverse effect on our business, financial condition, results of operations and cash flows.

In the case of Solana, we have a partnership with Liberty Interactive Corporation, or Liberty, pursuant to which Liberty agreed to invest $300 million in the parent company of the project entity, in exchange for the right to receive 61.20% of taxable losses and distributions until such time as Liberty reaches a certain rate of return, or the Flip Date, and 22.60% of taxable losses and distributions thereafter. Given the underperformance of the asset in the last years, we cannot assure the Flip Date will occur or when it will occur. We expect potential cash distributions from Solana to go mostly or entirely to Liberty in the upcoming years. If the Flip Date never occurs or if there is a delay longer than currently anticipated, this will adversely affect the cash flows expected from that project.

The generation of electric energy from renewable energy sources depends heavily on suitable meteorological conditions, and if solar or wind conditions are unfavorable, our electricity generation, and therefore revenue from our renewable energy generation facilities using our systems, may be substantially below our expectations.

The electricity produced, and revenues generated by a renewable energy generation facility are highly dependent on suitable solar or wind conditions, as applicable, and associated weather conditions, which are beyond our control. Furthermore, components of our system, such as structures, mirrors, absorber tubes, blades, PV panels or transformers are susceptible to being damaged by severe weather. In addition, replacement and spare parts for key components may be difficult or costly to acquire or may be unavailable.

Unfavorable weather and atmospheric conditions could impair the effectiveness of our assets or reduce their output beneath their rated capacity or require shutdown of key equipment, impeding operation of our renewable assets and our ability to achieve forecasted revenues and cash flows. As climate change increases the frequency and severity of severe weather conditions and may have the long-term effect of changing meteorological conditions at our project sites, such impairments may increase in frequency and/or severity.

We base our investment decisions with respect to each renewable generation facility on the findings of related wind and solar studies conducted on-site by third parties prior to construction or based on historical conditions at existing facilities. However, actual climatic conditions at a facility site, particularly wind conditions, which are sometimes severe, may not conform to the findings of these studies and therefore, our solar and wind energy facilities may not meet anticipated production levels or the rated capacity of its generation assets, which may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Disruption of the fuel supplies necessary to generate power at our efficient natural gas generation facilities may increase costs or result in disruptions in production.

Delivery of fossil fuels to fuel our efficient natural gas and some solar power generation facilities is dependent upon the infrastructure, including natural gas pipelines, available to serve each such generation facility, as well as upon the continuing financial viability of contractual counterparties. As a result, we are subject to the risks of disruptions or curtailments in the production of power at these generation facilities if a counterparty fails to perform or if there is a disruption in the relevant fuel delivery infrastructure. Increased costs and disruptions in production may have a material adverse effect in our business, results of operations and cash flows.

Maintenance, expansion and refurbishment of electric generation and other facilities involve significant risks that could result in unplanned power outages or reduced output or availability.

Although the facilities in our portfolio are relatively new, they may require periodic upgrading and improvement in the future. Any unexpected operational or mechanical failure, including failure associated with breakdowns and forced outages, could reduce the performance and availability of our facilities below expected levels, reducing our revenues. Degradation of the performance of our solar facilities above levels provided for in the related offtake agreements may also reduce its revenues. Unanticipated capital expenditures associated with maintaining, upgrading or repairing our facilities may also reduce profitability.

If we make any major modifications to our efficient natural gas or renewable power generation facilities or electric transmission lines, we may be required to comply with more stringent environmental regulations, which would likely result in substantial additional capital expenditures. We may also choose to repower, refurbish or upgrade our facilities based on our assessment that such activity will provide adequate financial returns. Such facilities require time for development and capital expenditures before commencement of commercial operations, and key assumptions underpinning a decision to make such an investment may prove incorrect, including assumptions regarding construction costs, timing, available financing and future fuel and power prices. This may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Risks Related to Our Relationship with Algonquin and Abengoa

Algonquin is our largest shareholder and exercises substantial influence over us.

Currently, Algonquin beneficially owns and is entitled to vote approximately 41.5% of our ordinary shares. As a result of this ownership, Algonquin has substantial influence on our affairs and their ownership interest and voting power constitute a significant percentage of the shares eligible to vote on any matter requiring the approval of our shareholders. Such matters include the election of directors, the adoption of amendments to our articles of association and approval of mergers or sale of all or a high percentage of our assets. This concentration of ownership may also have the effect of discouraging others from making tender offers for our shares. There can be no assurance that the interests of Algonquin will coincide with the interests of the purchasers of our shares or that Algonquin will act in a manner that is in our best interests. If Algonquin sells its shares to a single shareholder, that new shareholder could continue to exercise substantial influence and could seek to influence or change our strategy or corporate governance or could take effective control of us. In addition, we did not have a prior relationship with Algonquin and we have limited knowledge and visibility of their operations and plans.

Our ownership structure and certain service agreements may create significant conflicts of interest that may be resolved in a manner that is not in our best interests.

Our ownership structure involves a number of relationships that may give rise to certain conflicts of interest between us, Algonquin, and the rest of our shareholders. Currently, two of our directors are affiliated with Algonquin.

Currently, AAGES and Algonquin are related parties and may have interests that differ from our interests, including with respect to the types of acquisitions made, the timing and amount of dividends paid by us, the reinvestment of returns generated by our operations, the use of leverage when making acquisitions and the appointment of outside advisors and service providers. Any transaction between us and AAGES or Algonquin (including the acquisition of any ROFO assets or any co-investment with AAGES or Algonquin or any investment on an Algonquin asset) is subject to our related party transaction policy, which requires prior approval of such transaction by a majority of the non-conflicted directors, typically our independent directors. The existence of our related party transaction approval policy may not insulate us from derivative claims related to related party transactions and the conflicts of interest described in this risk factor. Regardless of the merits of such claims, we may be required to spend significant management time and financial resources in the defense thereof. Additionally, to the extent we fail to appropriately deal with any such conflicts, it could negatively impact our reputation and ability to raise additional funds and the willingness of counterparties to do business with us, all of which may have a material adverse effect on our business, financial condition, results of operations and cash flows.

If Abengoa defaults on certain of its debt obligations, we could potentially be in default of certain of our project financing agreements.

The project financing arrangement of Kaxu contains cross-default provisions related to Abengoa such that debt defaults by Abengoa, subject to certain threshold amounts and/or a restructuring process, could trigger a default under the Kaxu project financing arrangement. In March 2017, Atlantica obtained a waiver in its Kaxu project financing arrangement which waives any potential cross-defaults with Abengoa up to that date, but it does not cover potential future cross-default events.

Abengoa has been under a debt restructuring process recently, is currently seeking approval for another restructuring, and may default on its debt again in the future. If Abengoa defaults on its debt, there is no guarantee that we will be able to obtain additional cross-default waivers under the Kaxu project financing. Without a waiver, we would be in default of our obligations under the Kaxu project financing. A cross-default scenario, if not cured or waived, may entitle lenders to demand repayment or enforce on their security interests, which may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Abengoa’s financial condition could affect its ability to maintain existing guarantees and letters of credit under the Financial Support Agreement.

Although Abengoa sold its remaining 16.5% stake in our company to Algonquin in November 2018, Abengoa’s financial condition could still impact our business. Under the Financial Support Agreement with Abengoa, which was signed on June 13, 2014 and amended and restated on September 28, 2017, Abengoa agreed to maintain certain guarantees or letters of credit outstanding in our or any of our affiliates’ favor until June 13, 2019. Any failure by Abengoa to meet its obligations under such agreement may adversely affect our business or the operation of our facilities and may have a material adverse effect on our business, financial condition, results of operations and cash flows.

We depend on Abengoa to maintain certain existing guarantees and letters of credit in our favor under the Financial Support Agreement. As of December 31, 2018, the aforementioned guarantees amounted to $23 million. Despite completing the sale of our shares, and even though we have advanced plans in place, Abengoa is still liable under these agreements. If Abengoa were to fail to provide the requisite financial support, we would need to replace the financial guarantees provided by Abengoa and we may be unable to substitute guarantees and letters of credit from a third party on comparable terms, without undue delay or at all. In addition, as disclosed in our Annual Consolidated Financial Statements, we have current and future collection rights with certain subsidiaries of Abengoa. Moreover, Abengoa has a number of obligations and indemnities which have resulted or could result in additional liability obligations to us or our assets. Inability of Abengoa to pay their obligations when due would have a negative impact on our current or future cash position.

Abengoa’s financial condition could affect its ability to satisfy its obligations with us under different agreements, including (i) operation and maintenance agreements, (ii) Tenes share purchase agreement or (iii) warranties and guarantees in Kaxu pursuant to EPC contracts, as well as indemnities and other contracts in place.

A decline in the financial situation of Abengoa and of certain of its subsidiaries may result in a material adverse effect on our operation and maintenance agreements. Abengoa and its subsidiaries provide operation and maintenance services for many of our assets. We cannot guarantee that Abengoa and/or its subcontractors will be able to continue performing with the same level of service and under the same terms and conditions, and at the same prices. For instance, although we have separated our IT systems from Abengoa’s, we still rely on some of Abengoa’s operational IT systems and communications systems in some of our assets. If Abengoa faces a decline in its financial position, it may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Because we have long-term operation and maintenance agreements with Abengoa for many of our assets, if Abengoa cannot continue performing current services at the same prices, we may need to renegotiate contracts and pay higher prices or have a change in services. This could also cause us to change suppliers or to pay higher prices or change the level of services. This may have a material adverse effect on our business, results of operations, financial situation and cash flows. A decline in the financial situation of Abengoa may also result in a material adverse effect on Abengoa’s and its subsidiaries’ obligations, warranties and guarantees, indemnities, the Financial Support Agreement or any other agreement. In addition, Abengoa represented that further to the accession to the restructuring agreement, we would not be a guarantor of any obligation of Abengoa with respect to third parties and agreed to indemnify us for any penalty claimed by third parties resulting from any breach in such representations.

In January 2019, we entered into an agreement with Abengoa under the Abengoa ROFO Agreement for the acquisition of Befesa Agua Tenés, S.L.U., a holding company which owns a 51% stake of Tenes, a water desalination plant in Algeria. Closing of the acquisition is subject to conditions precedent, including the approval by the Algerian administration. At this stage, we cannot guarantee that we will obtain this approval nor the expected timing of such approval. The price agreed for the equity value is $24.5 million, of which $19.9 million were paid in January 2019 as an advanced payment and the rest is expected to be paid once the conditions precedent are fulfilled. If all the conditions precedent were not fulfilled by September 30, 2019, the advanced payment shall be progressively reimbursed by Abengoa through a full cash-sweep of all the dividends to be received and in any case no later than September 30, 2031, together with an annual 12% interest. If the acquisition did not close and Abengoa was not able to reimburse the advanced payment, this may have an adverse effect on our results of operations and cash flows.

Furthermore, pursuant to different agreeements, Abengoa has certain amounts payable to us and has provided guarantees and indemnities covering for example potential tax liabilities for assets acquired from Abengoa. If as a result of its financial situation Abengoa did not comply with these obligations, this could have a material adverse effect on our business, financial situation, results of operations and cash flows.

There may be unanticipated consequences of further restructuring by Abengoa or ongoing bankruptcy proceedings by Abengoa’s subsidiaries that we have not yet identified. There are uncertainties as to how any further bankruptcy proceedings would be resolved and how our relationship with Abengoa would be affected following the initiation or resolution of any such proceedings.

We may not be able to consummate future acquisitions from AAGES, Algonquin or Abengoa.

Our ability to grow through acquisitions depends, in part, on AAGES’, Algonquin’s and Abengoa’s ability to present us with acquisition opportunities. Abengoa has undergone a restructuring process in recent years. AAGES, Algonquin or Abengoa may have financial and resource constraints limiting or eliminating their ability to continue building the contracted assets which are currently under construction and may have financial and resource constraints limiting or eliminating their ability to develop and build new contracted assets. In addition, AAGES, Algonquin or Abengoa may sell assets under development and, in the case of Abengoa, under construction, before they reach their commercial operation date. In addition, on September 30, 2018, Abengoa announced that it had signed a term sheet with a group of financial entities and investors who would provide additional liquidity and bonding lines by the issuance of a mandatory convertible instrument issued at the level of A3T, a cogeneration asset in Mexico subject to our Abengoa ROFO Agreement. Closing is subject to certain conditions. The fact that Abengoa has used A3T as collateral and that Abengoa has signed PPAs with payments to be made in local currency may make our acquisition of this project under the Abengoa ROFO Agreement less likely. In addition, the Atacama project in Chile is currently owned by APW-1, an investment vehicle initially created by Abengoa as a joint venture with EIG and currently fully owned by EIG, an investment fund; although the Atacama project is subject to our ROFO agreement with APW-1, we cannot be certain that APW-1 will wish to sell the Atacama project at an attractive price or at all. Furthermore, there may be circumstances out of our control which limit our ability to acquire the rest of the assets in the Abengoa portfolio which are subject to the Abengoa ROFO Agreement.

AAGES and Algonquin may not offer us assets at all or may not offer us assets that fit within our portfolio or contribute to our growth strategy. Only certain assets outside the United States and Canada are included in the Algonquin ROFO Agreement. Furthermore, Algonquin can terminate its ROFO agreement with us with a 180-day notice.

Additionally, we may not reach an agreement on the price of assets offered by AAGES, Algonquin or Abengoa. For these reasons, we may not be able to consummate future acquisitions from AAGES, Algonquin or Abengoa which may restrict our ability to grow. Furthermore, we may not be able to renew the Abengoa ROFO Agreement. The Abengoa ROFO Agreement had an initial term of five years and has been extended until July 2022. We will be able to unilaterally extend the term of the Abengoa ROFO Agreement as many times as desired for an additional three-year period, provided that we have executed at least one acquisition in the previous two years after having been offered at least four projects.

All the above could limit our ability to grow, which may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Abengoa may be forced to initiate a bankruptcy filing under the Spanish Insolvency Act and, as a result, it may be subject to insolvency claw-back actions in which transactions may be set aside.

Under the Spanish Insolvency Act, the transactions a company has entered into during the two years prior to the opening of insolvency proceedings can be set aside, irrespective of whether there was intent to defraud, if those transactions are considered materially damaging to the insolvency estate. Material damage is assessed on the basis of the circumstances at the time the transaction was carried out, without the benefit of hindsight and without considering subsequent events or occurrences, including events in relation to insolvency proceedings or the request to set-aside the transaction. Though we could be considered a “connected person” for purposes of Spanish bankruptcy proceedings (which triggers a presumption of damage), transactions we have entered into with Abengoa in the previous two years before it may be declared insolvent (if such action were to take place) would not automatically be set aside. The court would consider if the transactions were detrimental to Abengoa on the terms on which they were made and the suitability of the transactions at the time they were entered into, if the transaction followed market standards and prices, had real economic value and if a transaction was carried out on the same conditions as it would have been by independent parties.

Table of Contents

In practice, transactions that are subject to claw-back with respect to companies in the same group relate to: (a) unjustified payments or advances from the insolvent company to another group company, (b) transfers of assets or rights by the insolvent company to another group company at below market value, (c) payment-in-kind arrangements in which the property another group company receives in payment is higher in value than the debt owed to it, and (d) security provided by the insolvent company for another group company’s obligations. This determination will be a question of fact before a Spanish court if Abengoa initiates a bankruptcy filing in Spain, however if any of the transactions entered into between us and Abengoa, including those related to drop-downs assets, were declared invalid by a Spanish court, unless it is determined we acted in bad faith, such transaction would be unwound and we would receive back the cash paid, which may have a material adverse effect on our business, financial condition, results of operations and cash flows.

The outcome of any bankruptcy proceedings that may be initiated by Abengoa would be difficult to predict given that Abengoa is incorporated in Spain and has assets and operations in several countries around the world. In the event of any bankruptcy or similar proceeding involving Abengoa or any of its subsidiaries, bankruptcy laws other than those of Spain could apply. The rights of Abengoa’s creditors may be subject to the laws of a number of jurisdictions and such multi-jurisdictional proceedings are typically complex and often result in substantial uncertainty. In addition, the bankruptcy and other laws of such jurisdictions may be materially different from, or in conflict with, one another. If Abengoa is subject to U.S. bankruptcy law, bankruptcy courts in the United States may seek to assert jurisdiction over all of its assets, wherever located, including property situated in other countries.

A bankruptcy filing by Abengoa may permanently affect Abengoa’s operations. We cannot predict how any bankruptcy proceeding would be resolved or how our relationship with Abengoa will be affected following the initiation of any such proceedings or after the resolution of any such proceedings. Any bankruptcy proceedings initiated by Abengoa may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Abengoa’s sales of our shares may increase the risk of divergence of interest between us and Abengoa.

In November 2018, Abengoa sold its remaining interest in our shares. As a result of its reduction of its ownership of us, Abengoa has less incentive than previously to advance our interests. If Abengoa fails to comply with its obligations or terminates operation and maintenance agreements, we would need to find alternative suppliers or alternative ways to perform those services and we cannot be certain that the service level, payment conditions or cost would be comparable to the current operations and maintenance contracts with Abengoa, especially in regard to assets with “all in” pricing arrangements.

Abengoa also has a number of obligations in several assets, mostly Solana and Kaxu, as an EPC supplier irrespective of its ownership in us.

In Solana, the EPC guarantee period for the Solana project expired without it reaching the expected production levels and Abengoa, as the EPC supplier, agreed to provide certain compensation to the Solana project. As a result, and in the context of the DOE consent to decrease Abengoa’s ownership in Atlantica to 16.5%, Solana received an aggregate amount of $120 million in payments from Abengoa ($42.5 million in December 2017 and $77.5 million in March 2018). Of the received sums, $95 million was used to repay project debt and $25 million was set aside to cover other Abengoa obligations. In addition, in November 2018 in the context of the DOE consent to allow Abengoa to sell entirely its stake in Atlantica, Solana received $16.5 million, of which $9 million were used to repay project debt and $7.5 million was set aside to cover potential repairs and other Abengoa obligations. Additionally, the long-term payments schedule signed between Abengoa and Solana was amended. This schedule was modified to $7.4 million semi-annually over 2 years and $10.3 million semi-annually over the subsequent 4 years, beginning in January 2019. Solana also received a parcel of land adjacent to the Solana site with an estimated value of approximately $7 million. Furthermore, Abengoa agreed to pay $13 million to fund a reserve account progressively in 2020 and 2021. In the event that Abengoa did not make these payments, we would need to make them and in return obtain compensation by reducing certain variable future liabilities in other operation and maintenance contracts with Abengoa.

In Kaxu, we reached an agreement with Abengoa as EPC supplier and the lenders under the project financing agreement to extend the production guarantee until October 2018. In the extended period, Kaxu reached the main target production parameters but not all of them, which resulted in obligations and guarantees of approximately $2 million. Kaxu’s dividend distributions to the holding company level are subject to a number of conditions, including the asset reaching formal completion and Abengoa fulfilling the previous obligations as EPC supplier. In exchange for that extension, Abengoa agreed to perform certain technical improvements in the heat exchangers and committed to provide an approximately $15 million letter of credit to guarantee the correct performance of those heat exchangers in the upcoming 5 years.

Risks Related to Our Indebtedness

Our indebtedness could expose us to the risk of increased interest rates and limit our ability to react to changes in the economy or our industry. It could also adversely affect our ability to raise additional capital to fund our operations or pay dividends.

As of December 31, 2018, we had approximately (i) $5,090.9 million of total indebtedness under various project-level debt arrangements and (ii) $684.1 million of total indebtedness under our corporate arrangements, which include the 2019 Notes, the three tranches of the €275 million Note Issuance Facility maturing in 2022, 2023, and 2024, and drawdowns under the Revolving Credit Facility.

Our substantial debt could have important negative consequences on our financial condition, including:

increasing our vulnerability to general economic and industry conditions;

requiring a substantial portion of our cash flow from operations to be dedicated to the payment of principal and interest on our indebtedness, therefore reducing our ability to pay dividends to holders of our shares or to use our cash flow to fund our operations, capital expenditures and future business opportunities;

limiting our ability to enter into long-term power sales, fuel purchases and swaps which require credit support;

limiting our ability to fund operations or future acquisitions;

restricting our ability to make certain distributions with respect to our shares and the ability of our subsidiaries to make certain distributions to us, in light of restricted payment and other financial covenants in our credit facilities and other financing agreements;

exposing us to the risk of increased interest rates because a portion of some of our borrowings (below 10% as of the date hereof) are at variable rates of interest;

limiting our ability to obtain additional financing for working capital, including collateral postings, capital expenditures, debt service requirements, acquisitions and general corporate or other purposes; and

limiting our ability to adjust to changing market conditions and placing us at a competitive disadvantage compared to our competitors who have less debt.

The operating and financial restrictions and covenants in the Indenture governing the 2019 Notes, the credit agreement governing the Revolving Credit Facility, and the facility agreement governing the Note Issuance Facility may adversely affect our ability to finance our future operations or capital needs, to engage in other business activities that may be in our interest and to execute our business strategy as we intend to do so. Each contains covenants that limit certain of our and the guarantors’ activities. If we violate any of these covenants, a default may result, which, if not cured or waived, could result in the acceleration of our debt. See “Item 5.B—Operating and Financial Review and Prospects—Liquidity and Capital Resources—Financing Arrangements—Revolving Credit Facility.”

Our inability to satisfy certain financial covenants may prevent cash distributions by the particular project(s) to us and, our failure to comply with those and other covenants could result in an event of default which, if not cured or waived, may entitle the related lenders to demand repayment or enforce their security interests, which may have a material adverse effect on our business, results of operations, financial condition and cash flows. In addition, failure to comply with such covenants, including covenants under the Revolving Credit Facility, the Indenture and the Note Issuance Facility, may entitle the related noteholders or lenders, as applicable, to demand repayment and accelerate all such indebtedness. If our project-level subsidiaries are unable to make distributions, it would likely have a material adverse effect on our ability to pay dividends to holders of our shares.

Table of Contents

Letter of credit facilities or personal guarantees to support project-level contractual obligations generally need to be renewed, at which time we will need to satisfy applicable financial ratios and covenants. If we are unable to renew the letters of credit as expected or replace them with letters of credit under different facilities on favorable terms or at all, we may experience a material adverse effect on our business, financial condition, results of operations and cash flows. Furthermore, such inability may constitute a default under certain project-level financing arrangements, restrict the ability of the project-level subsidiary to make distributions to us and/or reduce the amount of cash available at such subsidiary to make distributions to us.

We may not be able to refinance our existing indebtedness.

Our ability to arrange financing, either at the corporate level or at a non-recourse project-level subsidiary, and the costs of such capital, are dependent on numerous factors, including:

general economic and capital market conditions;

credit availability from banks and other financial institutions;

investor confidence in us and our partner Algonquin, as our largest shareholder;

our financial performance and the financial performance of our subsidiaries;

our level of indebtedness and compliance with covenants in debt agreements;

maintenance of acceptable project credit ratings or credit quality;

cash flow; and

provisions of tax and securities laws that may impact raising capital.

We may not be successful in obtaining additional capital for these or other reasons. Furthermore, we may be unable to refinance or replace project-level financing arrangements or other credit facilities on favorable terms or at all upon the expiration or termination thereof. Our failure, or the failure of any of our projects, to obtain additional capital or enter into new or replacement financing arrangements when due may constitute a default under such existing indebtedness and may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Potential future defaults by our subsidiaries, our off-takers, our suppliers, Abengoa or other persons could adversely affect us.

The financing agreements of our project subsidiaries are primarily loan agreements and related documents which, except as noted below, require the loans to be repaid solely from the revenue of the project being financed thereby, and provide that the repayment of the loans (and interest thereon) is secured solely by the shares, physical assets, contracts and cash flow of that project company. This type of financing is usually referred to herein as “project debt.” As of December 31, 2018, we had $5,090.9 million of outstanding indebtedness under various project-level debt arrangements.

While the lenders under our project debt do not have direct recourse to us or our subsidiaries (other than the project borrowers under those financings), defaults by the project borrowers under such financings can still have important consequences for us and our subsidiaries, including, without limitation:

reducing our receipt of dividends, fees, interest payments, loans and other sources of cash, since the project company will typically be prohibited from distributing cash to us and our subsidiaries during the pendency of any default;

default under our other debt instruments;

Table of Contents

causing us to record a loss in the event the lender forecloses on the assets of the project company; and

the loss or impairment of investors’ and project finance lenders’ confidence in us.

default under our other debt instruments;

causing us to record a loss in the event the lender forecloses on the assets of the project company; and

the loss or impairment of investors’ and project finance lenders’ confidence in us.

If we were to fail to satisfy any of our debt service obligations or to breach any related financial or operating covenants, the applicable lender could declare the full amount of the relevant indebtedness to be immediately due and payable and could foreclose on any assets pledged as collateral.

In addition, the financing arrangement of Kaxu contained cross-default provisions related to Abengoa, such that debt defaults by Abengoa, subject to certain threshold amounts and/or a restructuring process, could trigger defaults under such project financing arrangement. In March 2017, the Company signed a waiver which gives clearance to cross-defaults that might have arisen from Abengoa insolvency and restructuring up to that date, but does not extend to potential future cross-default events.

Under the Revolving Credit Facility, a payment default by one or more of our non-recourse subsidiaries representing more than 25% of the cash available for distribution distributed in the previous four fiscal quarters could trigger a default. In addition, our Note Issuance Facility includes a cross-default provision related to a payment default by one or more of our non-recourse subsidiaries representing more than 20% of the cash available for distribution distributed in the previous four fiscal quarters could trigger a default, provided that these subsidiaries have an indebtedness higher than $100 million in the case of non-recourse subsidiaries or more than $75 million in the case of subsidiaries other than non-recourse subsidiaries.

Any of these events may have a material adverse effect on our business, financial condition, results of operations or cash flows.

A change of control may have negative implications for us.

If any investor acquires more than 50.0% of our shares, we may be required to refinance all or part of our corporate debt or obtain waivers from the lending financial institutions, due to the fact that they contain customary change of control provisions. Additionally, we could see an increase in the yearly state property tax payment in Mojave, which would be evaluated by the tax authority at the time the change of control potentially occurred. Our best estimate with current information available and subject to further analysis is that we could have an incremental annual payment of property tax of approximately $12 million to $14 million annually, which could potentially decrease progressively over time as the asset depreciates.

Risks Related to Ownership of Our Shares

We may not be able to pay a specific or increasing level of cash dividends to holders of our shares in the future .

The amount of our cash available for distribution principally depends upon the amount of cash we generate from our operations, which will fluctuate from quarter to quarter based on, among other things:

the level of our operating and general and administrative expenses;

seasonal variations in revenues generated by the business;

operational performance of our assets;

Table of Contents

potential capital expenditure requirements in our assets in the case there were technical problems not covered by the EPC contractor guarantee or by insurance;

our debt service requirements and other liabilities;

fluctuations in our working capital needs;

our ability to borrow funds;

restrictions contained in our debt agreements (including our project-level financing);

changes in our revenues due to delays in collections from our offtakers, legal disputes regarding contact terms or adjustments contemplated in existing regulation or changes in regulation or taxes in the countries in which we operate;

potential restrictions on payment of dividends arising from the bankruptcy of PG&E;

potential restrictions on payment of dividends arising from cross-default provisions with Abengoa in our Kaxu project financing agreements; and

other business risks affecting our cash levels.

As a result of all these factors, we cannot guarantee that we will have sufficient cash generated from operations to pay a specific or increasing level of cash dividends to holders of our shares. Furthermore, holders of our shares should be aware that the amount of cash available for distribution depends primarily on our cash flow, and is not solely a function of profitability, which is affected by non-cash items. We may incur other expenses or liabilities during a period that could significantly reduce or eliminate our cash available for distribution and, in turn, impair our ability to pay dividends to shareholders during the period. Because we are a holding company, our ability to pay dividends on our shares is limited by restrictions or limitations on the ability of our subsidiaries to pay dividends or make other distributions, such as pursuant to shareholder loans, capital reductions or other means, to us, including restrictions under the terms of the agreements governing project-level financing, the 2019 Notes, the Revolving Credit Facility, the Note Issuance Facility or legal, regulatory or other restrictions or limitations applicable in the various jurisdictions in which we operate, such as exchange controls or similar matters or corporate law limitations, any of which could change from time to time and thereby limit our subsidiaries’ ability to pay dividends or make other distributions to us. Our project-level financing agreements generally prohibit distributions to us unless certain specific conditions are met, including the satisfaction of financial ratios.

In 2016, our board of directors decided not to pay a dividend with respect to the first quarter, and declared a reduced dividend in the following quarters, based on the fact that certain of our assets contain cross default provisions and change of ownership provisions with Abengoa. In 2017 and 2018, with the receipt of most waivers, we progressively increased our dividends. However, we cannot assure you that our board of directors will not take similar measures in upcoming periods.

Our cash available for distribution will likely fluctuate from quarter to quarter, in some cases significantly, due to seasonality. See “Item 4.B—Business Overview—Seasonality.” As result, we may reduce the amount of cash we distribute in a particular quarter to establish reserves to fund distributions to shareholders in future periods for which the cash distributions we would otherwise receive from our subsidiary project companies would otherwise be insufficient to fund our quarterly dividend. If we fail to establish sufficient reserves, we may not be able to maintain our quarterly dividend with a respect to a quarter adversely affected by seasonality.

Dividends to holders of our shares will be paid at the discretion of our board of directors. Our board of directors may decrease the level of or entirely discontinue payment of dividends. Our board of directors may change our dividend policy at any point in time or modify the dividend for specific quarters following prevailing conditions. For a description of additional restrictions and factors that may affect our ability to pay cash dividends, please see “Item 8.A—Consolidated Statements and Other Financial Information—Dividend Policy.”

Table of Contents

We are a holding company and our only material assets are our interests in our subsidiaries, upon whom we are dependent for distributions to pay dividends, taxes and other expenses .

We are a holding company whose sole material assets consist of our interests in our subsidiaries. We do not have any independent means of generating revenue. We intend to cause our operating subsidiaries to make distributions to us in an amount sufficient to cover our corporate debt services, corporate general and administrative expenses, all applicable taxes payable and dividends, if any, declared by us. To the extent that we need funds for a quarterly cash dividend to holders of our shares or otherwise, and one or more of our operating subsidiaries is restricted from making such distributions under the terms of its financing or other agreements or applicable law and regulations or is otherwise unable to provide such funds, it could materially adversely affect our liquidity and financial condition and limit our ability to pay dividends to shareholders.

We have a limited operating history and as a result there is no assurance we can operate on a profitable basis .

We have a limited operating history on which to base an evaluation of our business and prospects. Our prospects must be considered in light of the risks, expenses and difficulties frequently encountered by companies in their early stages of operation. We cannot assure you that we will be successful in addressing the risks we may encounter, and our failure to do so could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Market interest rates may have an effect on the value of our shares .

One of the factors that will influence the price of our shares will be the effective dividend yield of our shares (i.e., the yield as a percentage of the then-market price of our shares) relative to market interest rates. A continued increase in market interest rates, which are still at relatively low levels compared to historical rates, may lead prospective purchasers of our shares to expect a higher dividend yield. In the United States, interest rates, and expectations of still higher interest rates, have increased over the past year in the markets. At the end of 2018, equities in the United States experienced a downturn which has also affected utilities and the yieldco sector. The low price of our shares might make our dividend per share growth more difficult, since acquisitions financed with equity could be less accretive or not accretive. Our inability to increase our dividend as a result of an increase in borrowing costs, insufficient cash available for distribution or otherwise could result in selling pressure on, and a decrease in, the market price of our shares as investors seek alternative investments with higher yield.

Market volatility may affect the price of our shares and the value of your investment .

The market for securities issued by issuers such as us is influenced by economic and market conditions and, to varying degrees, market conditions, interest rates, currency exchange rates and inflation rates in other countries. There can be no assurance that events in the United States, Latin America, Europe, Africa or elsewhere will not cause market volatility or that such volatility will not adversely affect the price of the shares or that economic and market conditions will not have any other adverse effect. Fluctuations in interest rates may give rise to arbitrage opportunities based upon changes in the relative value of the shares. Any trading by arbitrageurs could, in turn, affect the trading price of the shares. In the past there has been correlation between the price of our shares, the price of oil and the price of shares of master limited partnerships, or MLPs, and a decline in the price of oil or MLP shares could cause a decline in the price of our shares. The price of our shares can also be affected by our peers’ share price. Securities markets in general may experience extreme volatility that is unrelated to the operating performance of particular companies. Any broad market fluctuations may adversely affect the trading of our shares.

In addition, the market price of our shares may fluctuate in the event of negative developments at Algonquin, the termination of the AAGES, Abengoa, Algonquin or Abengoa ROFO Agreements, or additions or departures of our key personnel, changes in market valuations of similar companies, Algonquin or Abengoa and/or speculation in the press or investment community regarding us, Algonquin or Abengoa.

Table of Contents

You may experience dilution of your ownership interest due to the future issuance of additional shares .

In order to finance our business and in order to finance the growth of our business through future acquisitions, we may require additional funds from further equity or debt financings, including tax equity financing transactions or sales of preferred shares or other classes of shares or convertible debt or convertible equity issued by a subsidiary. We may need to issue equity to complete future acquisitions, expansions and capital expenditures. We may also need to issue equity for other reasons, including paying the general and administrative costs of our business or our corporate debt. In the future, we may issue our previously authorized and unissued securities, resulting in the dilution of the ownership interests of purchasers of our shares offered hereby. The potential issuance of additional shares or preferred stock or convertible debt may create downward pressure on the trading price of our shares. We may also issue additional shares or other securities that are convertible into or exercisable for our shares in future public offerings or private placements for capital-raising purposes or for other business purposes, potentially at an offering price, conversion price or exercise price that is below the offering price for our shares in any of our previous offering.

If securities or industry analysts do not publish or cease to publish research or reports about us, our business or our market, or if they change their recommendations regarding our shares adversely, the price and trading volume of our shares could decline .

The trading market for our shares will be influenced by the research and reports that industry or securities analysts may publish about us, Algonquin, our business, our market or our competitors. If any of the analysts who may cover us change their recommendations regarding our shares adversely, or provide more favorable relative recommendations about our competitors, the price of our shares would likely decline. If any analyst who may cover us were to cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the price or trading volume of our shares to decline.

Future sales of our shares by Algonquin or its lenders or by other substantial shareholders may cause the price of our shares to fall .

The market price of our shares could decline as a result of future sales by Algonquin of its shares in the market, or the perception that these sales could occur. Following the completion of the Share Sale, Algonquin owns 41.5% of our ordinary shares. On November 28, 2018, AAGES obtained a secured credit facility in the amount of $306,500,000. The AAGES secured credit facility is collateralized through a pledge of the Atlantica shares held by AY Holdings. A collateral shortfall would occur if the net obligation as defined in the agreement would equal or exceed 50% of the market value of the Atlantica shares in which case the AAGES Credit Facility lenders would have the right to sell Atlantica shares to eliminate the collateral shortfall.

If AAGES defaulted on any of these financing arrangements, its lenders may foreclose on the shares and sell the shares in the market. Future sales of substantial amounts of the shares and/or equity-related securities in the public market, or the perception that such sales could occur, could adversely affect prevailing trading prices of the shares and could impair our ability to raise capital through future offerings of equity or equity-related securities. The price of the shares could be depressed by investors’ anticipation of the potential sale in the market of substantial additional amounts of shares. Disposals of shares could increase the number of shares being offered for sale in the market and depress the trading price of our shares.

As a “foreign private issuer” in the United States, we are exempt from certain rules under the U.S. securities laws and are permitted to file less information with the SEC than U.S. companies .

As a “foreign private issuer,” we are exempt from certain rules under the Exchange Act that impose certain disclosure obligations and procedural requirements for proxy solicitations under Section 14 of the Exchange Act. In addition, our officers, directors and principal shareholders are exempt from the reporting and “short-swing” profit recovery provisions of Section 16 of the Exchange Act and the rules under the Exchange Act with respect to their purchases and sales of our shares. Moreover, we are not required to file periodic reports and financial statements with the SEC as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act. In addition, we are not required to comply with Regulation FD, which restricts the selective disclosure of material information.

If we were to lose our “foreign private issuer” status, we would no longer be exempt from certain provisions of the U.S. securities laws we would be required to commence reporting on forms required of U.S. companies, and we could incur increased compliance and other costs, among other consequences.

Judgments of U.S. courts may not be enforceable against us .

Judgments of U.S. courts, including those predicated on the civil liability provisions of the federal securities laws of the United States, may not be enforceable in courts in the United Kingdom or other countries in which we operate. As a result, our shareholders who obtain a judgment against us in the United States may not be able to require us to pay the amount of the judgment.

Table of Contents

There are limitations on enforceability of civil liabilities under U.S. federal securities laws .

We are incorporated under the laws of England and Wales. Most of our officers and directors reside outside of the United States. In addition, a portion of our assets and the majority of the assets of our directors and officers are located outside the United States. As a result, it may be difficult or impossible to serve legal process on persons located outside the United States and to force them to appear in a U.S. court. It may also be difficult or impossible to enforce a judgment of a U.S. court against persons outside the United States, or to enforce a judgment of a foreign court against such persons in the United States. We believe that there may be doubt as to the enforceability against persons in England and Wales and in Spain, whether in original actions or in actions for the enforcement of judgments of U.S. courts, of civil liabilities predicated solely upon the laws of the United States, including its federal securities laws. Because we are a foreign private issuer, our directors and officers will not be subject to rules under the Exchange Act that under certain circumstances would require directors and officers to forfeit to us any “short-swing” profits realized from purchases and sales, as determined under the Exchange Act and the rules thereunder, of our equity securities. In addition, punitive damages in actions brought in the United States or elsewhere may be unenforceable in England and Wales and in Spain.

Shareholders in certain jurisdictions may not be able to exercise their pre-emptive rights if we increase our share capital .

Under our articles of association, holders of our shares generally have the right to subscribe and pay for a sufficient number of our shares to maintain their relative ownership percentages prior to the issuance of any new shares in exchange for cash consideration. Holders of shares in certain jurisdictions may not be able to exercise their pre-emptive rights unless securities laws have been complied with in such jurisdictions with respect to such rights and the related shares, or an exemption from the requirements of the securities laws of these jurisdictions is available. To the extent that such shareholders are not able to exercise their pre-emptive rights, the pre-emptive rights would lapse, and the proportional interests of such holders would be reduced.

In addition, under the Shareholders Agreement, AAGES or Algonquin or both of them may subscribe in cash for (i) up to 100.0% of our ordinary shares if the purpose of the issuance is to fund our acquisition of assets under the AAGES or Algonquin ROFO Agreement; and (ii) up to 66.0% of our ordinary shares if the purpose of the issuance is to fund our acquisition of assets under the Abengoa ROFO Agreement. If we issue ordinary shares for any other purpose, AAGES or Algonquin may subscribe in cash for our ordinary shares in a pro rata amount of such AAGES’ or Algonquin’s aggregate holding of voting rights in us. The Shareholders Agreement may be terminated or modified in the future.

The rights of our shareholders may differ from the rights typically offered to shareholders of a U.S. corporation organized in Delaware .

We are incorporated under English law. The rights of holders of our shares are governed by English law, including the provisions of the UK Companies Act 2006, and by our articles of association. These rights differ in certain respects from the rights of shareholders in typical U.S. corporations organized in Delaware. The principal differences are set forth in “Item 10.B—Memorandum and Articles of Association.”

Provisions in the UK City Code on Takeovers and Mergers may have anti-takeover effects that could discourage an acquisition of us by others, even if an acquisition would be beneficial to our shareholders .

The UK City Code on Takeovers and Mergers, or the Takeover Code, applies, among other things, to an offer for a public company whose registered office is in the United Kingdom and whose securities are not admitted to trading on a regulated market in the United Kingdom if the company is considered by the Panel on Takeovers and Mergers, or the Takeover Panel, to have its place of central management and control in the United Kingdom. This is known as the “residency test.” The test for central management and control under the Takeover Code is different from that used by the UK tax authorities. Under the Takeover Code, the Takeover Panel will determine whether we have our place of central management and control in the United Kingdom by looking at various factors, including the structure of our board of directors, the functions of the directors and where they are resident.

Table of Contents

If at the time of a takeover offer the Takeover Panel determines that we have our place of central management and control in the United Kingdom, we would be subject to a number of rules and restrictions, including but not limited to the following: (1) our ability to enter into deal protection arrangements with a bidder would be extremely limited; (2) we may not, without the approval of our shareholders, be able to perform certain actions that could have the effect of frustrating an offer, such as issuing shares or carrying out acquisitions or disposals; and (3) we would be obliged to provide equality of information to all bona fide competing bidders.

Risks Related to Taxation

Changes in our tax position can significantly affect our reported earnings and cash flows.

Changes in corporate tax rates and/or other relevant tax laws in the United Kingdom, the United States or the other countries in which our assets are located may have a material impact on our future tax rate and/or our required tax payments. Such changes may include measures enacted in response to the ongoing initiatives in relation to fiscal legislation at an international level, such as the Action Plan on Base Erosion and Profit Shifting of the Organization for Economic Co-operation and Development. The final determination of our tax liability could be different from the forecasted amount, which may have a material adverse effect on our business, results of operations, financial condition and cash flows. Changes to the U.K. controlled foreign company rules or adverse interpretations of them, could have an impact on our future tax rate and/or our required tax payments. With respect to some of our projects, we must meet defined requirements to apply favorable tax treatment, such as lower tax rates or exemptions. We intend to meet these requirements in order to benefit from the favorable tax treatment; however, there can be no assurance that we will be able to comply with all of the necessary requirements in the future, or the requirements could change or be interpreted in another manner, which could give rise to a greater tax liability and which may have a material adverse effect on our business, results of operations, financial condition and cash flows.

In addition, according to public information, the government of Spain, which has been in office since June 2018, has proposed a modification to the tax legislation to limit certain deductions and introduces a minimum tax rule in the Corporate Income Tax. The proposed modification would also contemplate a reduction in the tax exemption on dividends received from affiliates from 100% to 95% exemption. This modification is subject to approval by the parliament and could be changed in the future. In addition, the details of the new regulation are still largely unknown. Based on available public information we do not expect a significant impact in cash flows from our Spanish solar assets in the upcoming years. In addition, since elections are scheduled to take place in April in Spain, the draft may not be approved.

Our future tax liability may be greater than expected if we do not use NOLs sufficient to offset our taxable income.

We expect to generate NOLs that we can use to offset future taxable income. Based on our current portfolio of assets, which include renewable assets that benefit from an accelerated tax depreciation schedule, and subject to potential tax audits, which may result in income, sales, use or other tax obligations, we do not expect to pay significant taxes in the upcoming years.

Although we expect these NOLs will be available as a future benefit, in the event that they are not generated as expected, or are successfully challenged by the local tax authorities, such as the IRS or Her Majesty’s Revenue and Customs among others, by way of a tax audit or otherwise, or are subject to future limitations as discussed below, our ability to realize these benefits may be limited. A reduction in our expected NOLs, a limitation on our ability to use such NOLs or the occurrence of future tax audits may result in a material increase in our estimated future income tax liability and may have a material adverse effect on our business, results of operations, financial condition and liquidity.

Our ability to use U.S. NOLs to offset future income may be limited.

We have generated significant U.S. NOLs. We generally are able to carry U.S. NOLs forward to reduce our tax liability in future years. Federal U.S. NOLs generated on or before December 31, 2017 can generally be carried back two years and carried forward for up to twenty years and can be applied to offset 100% of taxable income in such years. Under the TCJA, however, federal U.S. NOLs incurred in 2018 and in future years may be carried forward indefinitely but may not be carried back and the deductibility of such federal U.S. NOLs is limited to 80% of taxable income in such years. It is uncertain how various states will respond to the newly enacted federal tax law.

Table of Contents

In addition, our ability to use U.S. NOLs generated is subject to the rules of Sections 382 of the IRC. This section generally restricts the use of U.S. NOLs if we were to experience an “ownership change” as defined under Section 382 of the IRC, and similar state rules. In general, an “ownership change” would occur if our “5-percent shareholders,” as defined under Section 382 of the IRC, collectively increased their ownership in us to more than 50 percentage points over a rolling three-year period. A corporation that experiences an ownership change will generally be subject to an annual limitation on the use of its pre-ownership change U.S. NOLs equal to the equity value of the corporation immediately before the ownership change, multiplied by the long-term tax-exempt rate for the month in which the ownership change occurs, and increased by a certain portion of any “built-in-gains.”

The Abengoa restructuring carried out in 2017 caused a change of ownership under Section 382 of the IRC, which limited in part our ability to use net operating loss carryforwards. The 41.5% Share Sale by Abengoa of its stake in us may have caused another change of ownership, which may limit further our ability to use net operating loss carryforwards in the United States. Future sales by our largest shareholder, future equity issuances and in general the activity of our direct or indirect shareholders may limit further our ability to use net operating loss carryforwards in the United States, which could have a potential adverse effect on cash flows from U.S. assets expected in the future.

In addition, because we have recorded tax credits for the U.S. tax losses carryforwards in the past, a limit to our ability to use U.S. NOLs could result in writing off tax credits, which could cause a substantial non-cash income tax expense in our financial statements.

The TCJA may adversely affect the value of our NOLs and limit our ability to claim deductions for interest.

The TCJA, among other things, significantly reduces the U.S. federal tax rate applicable to corporations, imposes significant additional limitations on the deductibility of interest, temporarily allows for the expensing of certain capital expenditures, limits the deduction for NOLs to 80% of current year taxable income and eliminates NOL carrybacks, in each case, in general, for losses arising in taxable years beginning after December 31, 2017 (though any such NOLs may be carried forward indefinitely). Our NOLs have been revalued at the newly enacted U.S. corporate rate, and the impact has been recognized in our tax expense for 2017. Additionally, while the ITC and the PTC available for renewable energy investments in the United States were left unchanged, the lower corporate tax rate and the new base erosion anti-abuse tax (intended to prevent international groups from ‘earnings stripping’ through certain payments to foreign affiliates) may impact the cost and availability of tax equity financing, which could have a negative effect on our growth prospects in the United States. We continue to examine the impact this tax reform legislation may have on our business. The impact of this tax reform on stockholders is uncertain and could be adverse. We urge prospective investors to consult with their legal and tax advisors with respect to such legislation and the potential tax consequences of investing in our shares.

Distributions to U.S. Holders of our shares may be fully taxable as dividends .

It is difficult to predict whether or to what extent we will generate earnings or profits as computed for U.S. federal income tax purposes in any given tax year. If we make distributions on the shares from current or accumulated earnings and profits as computed for U.S. federal income tax purposes, such distributions generally will be taxable to U.S. Holders of our shares as ordinary dividend income for U.S. federal income tax purposes. Under current law, if certain requirements are met, such dividends would be eligible for the lower tax rates applicable to qualified dividend income of certain non-corporate U.S. Holders. While we expect that a portion of our distributions to U.S. Holders of our shares may exceed our current and accumulated earnings and profits as computed for U.S. federal income tax purposes, and therefore may constitute a non-taxable return of capital to the extent of a U.S. Holder’s basis in our shares, no assurance can be given that this will occur. We intend to calculate our earnings and profits annually in accordance with U.S. federal income tax principles. See “Item 10.E—Taxation—Material U.S. Federal Income Tax Considerations.”

Table of Contents

If we are a passive foreign investment company for U.S. federal income tax purposes for any taxable year, U.S. Holders of our shares could be subject to adverse U.S. federal income tax consequences .

If we were a PFIC for any taxable year during which a U.S. Holder held our shares, certain adverse U.S. federal income tax consequences may apply to the U.S. Holder. We do not believe that we were a PFIC for our 2018 taxable year and do not expect to be a PFIC for U.S. federal income tax purposes for the current taxable year or in the foreseeable future. However, PFIC status depends on the composition of a company’s income and assets and the fair market value of its assets (including, among others, less than 25.0% owned equity investments) from time to time, as well as on the application of complex statutory and regulatory rules that are subject to potentially varying or changing interpretations. Accordingly, there can be no assurance that we will not be considered a PFIC for any taxable year.

If we were a PFIC, U.S. Holders of our shares may be subject to adverse U.S. federal income tax consequences, such as taxation at the highest marginal ordinary income tax rates on capital gains and on certain actual or deemed distributions, interest charges on certain taxes treated as deferred, and additional reporting requirements. See “Item 10.E—Taxation—Material U.S. Federal Income Tax Considerations—Passive foreign investment company rules.”

Changes in tax regimes may affect us adversely

We have assets in different jurisdictions, which are subject to different tax regimes. There have been recent changes in tax laws in the United States and in Spain there might be also changes in the upcoming months. Changes in tax regimes such as the reduction or elimination of tax benefits, or the reduction of tax rates overall in markets where we operate could adversely affect the market for investments in our projects by third parties. A reduction in corporate tax rates could make investments in renewable projects less attractive to potential tax equity investors, in which case we may not be able to obtain third-party financing on terms as beneficial as in the past, or at all, which could limit our ability to grow our business. Limitations on the deductibility of interest expense could reduce our ability to deduct the interest we pay on our debt. These and other potential changes in tax regulations could have a material adverse effect on our results and cash flows.

ITEM 4.

INFORMATION ON THE COMPANY

A.	History and Development of the Company

We were incorporated in England and Wales as a private limited company on December 17, 2013 under the name “Abengoa Yield Limited.” On March 19, 2014, we were re-registered as a public limited company, under the name “Abengoa Yield plc.” On January 7, 2016, we changed our corporate brand to Atlantica Yield. At our annual shareholders meeting held in May 2016, we changed our legal name to Atlantica Yield plc.

The address of our principal executive offices is Great West House, GW1, 17th floor, Great West Road, Brentford, United Kingdom TW8 9DF, and our phone number is +44 203 499 0465.

Our current agent in the U.S. is ASHUSA Inc., a Delaware company with its principal office located at 1553 W. Todd Drive, Suite 204, Tempe, Arizona 85283, United States.

We are a sustainable total return company that owns and manages renewable energy, efficient natural gas (previously named “conventional”) power, electric transmission lines and water assets, focused on North America (the United States and Mexico), South America (Peru, Chile and Uruguay) and EMEA (Spain, Algeria and South Africa). We intend to expand maintaining North America, South America and Europe as our core geographies.

We own or have an interest in a portfolio of high-quality and diversified assets in terms of type of asset, technology and geographic footprint. Our portfolio consists of 24 assets with 1,496 MW of aggregate renewable energy installed generation capacity, 300 MW of efficient natural gas-fired power generation capacity, 10.5 M ft3 per day of water desalination and 1,152 miles of electric transmission lines.

On June 18, 2014, we completed our IPO and listed our shares on the NASDAQ Global Select Market under the symbol “ABY.” On November 14, 2017, the ticker symbol was changed to “AY.” Prior to the consummation of our IPO, Abengoa transferred to us ten assets representing an initial portfolio comprising 710 MW of renewable energy generation, 300 MW of efficient natural gas (previously named “conventional”) power generation and 1,018 miles of electric transmission lines and an exchangeable preferred equity investment in ACBH. The assets in the initial portfolio consisted of:

Table of Contents

Renewable energy assets in the initial public offering consisted of (i) two solar power plants in the United States, Solana and Mojave, each with a gross capacity of 280 MW; (ii) one on-shore wind farm in Uruguay, Palmatir, with a gross capacity of 50 MW and (iii) a solar power complex in Spain, Solaben 2/3, with a gross capacity of 100 MW.

Efficient natural gas assets consisting of ACT Energy Mexico, or ACT, a 300 MW cogeneration plant in Mexico.

Electric transmission lines consisting of (i) two lines in Peru, ATN and ATS, spanning a total of 931 miles; and (ii) three lines in Chile, Quadra 1, Quadra 2, and Palmucho, spanning a total of 87 miles.

Upon our IPO, we signed an exclusive agreement with Abengoa, which we refer to as the Abengoa ROFO Agreement, which provides us with a right of first offer on any proposed sale, transfer or other disposition of any of Abengoa’s contracted renewable energy, efficient natural gas, electric transmission or water assets in operation and located in the United States, Canada, Mexico, Chile, Peru, Uruguay, Brazil, Colombia and the European Union, as well as four assets in selected countries in Africa, the Middle East and Asia.

On November 1, 2017, Algonquin agreed to acquire 25.0% of our shares from Abengoa at a price of $24.25 per share, and upon completion of the Share Sale, became our largest shareholder. In addition, Algonquin and Abengoa created a joint venture, AAGES, to jointly invest in the development and construction of clean energy and water infrastructure contracted assets. On March 5, 2018 we also entered into a ROFO agreement with AAGES, which provides us with a right of first offer on any proposed sale, transfer or other disposition of AAGES ROFO Assets. Some of the assets currently under construction by Abengoa may be transferred to AAGES and our ROFO agreement with AAGES will include these assets. We entered into a ROFO agreement with Algonquin covering certain of their non-U.S. and non-Canadian assets.

Along with the 25.0% of our shares Algonquin acquired from Abengoa in November 2017, Algonquin acquired the remaining 16.5% of our shares held by Abengoa on November 27, 2018, bringing its total equity interest in Atlantica up to 41.5%.

Recent Acquisitions

In February 2018, we completed the acquisition of a 4 MW mini-hydroelectric power plant in Peru for a cash consideration of approximately $9 million. The plant reached COD in 2012. It has a fixed-price concession agreement denominated in U.S. dollars with the Ministry of Energy of Peru and the price is adjusted annually in accordance with the U.S. Consumer Price Index. See “—Our Operations—Renewable Energy” for a description of such assets.

In October 2018 we reached an agreement to acquire PTS, a natural gas transportation platform located in the Gulf of Mexico, close to ACT, our efficient natural gas plant. PTS will have an installed compression capacity of 450 million standard cubic feet per day and is currently under construction. The service agreement signed with Pemex on October 18, 2017 is a “take-or-pay” 11-year term contract starting in 2020, with a possibility of future extension at the discretion of both parties. The share purchase agreement is structured to acquire the asset in stages. On October 10, 2018, we acquired a 5% ownership in the project; once the project begins operation, we will acquire an additional 65% stake; finally, we will acquire the remaining 30% one year after COD, subject to final approvals. The total equity investment is estimated to be approximately $150 million.

In December 2018, we completed the acquisition transaction for an expansion of our ATN transmission line by acquiring a 220-kV power substation and two small transmission lines in Peru. The substation connects our line to the Shahuindo mine located nearby. The asset has a U.S. dollar-denominated 15-year contract in place with Shahuindo mine, a fully owned subsidiary of Tahoe Resources Inc., a company listed in the Toronto and New York stock exchanges. Construction finished on December 28, 2018, and part of the price is expected to be paid after the technical connection tests are finished. The total purchase price is expected to be approximately $16 million.

Table of Contents

In December 2018, we completed the acquisition of Chile TL3, a transmission line currently in operation in Chile. The asset has a tariff under the regulation in place in Chile, denominated in U.S. dollars and indexed to U.S. and Chilean inflation rates. Our investment amounted to approximately $6 million.

In December 2018, we completed the acquisition of Melowind, a 50 MW wind plant in Uruguay, from Enel Green Power S.p.A. The asset has been in operation since 2015 and has a 20-year US$-denominated PPA in place for 100% of the electricity produced. The off-taker is the state-owned power company UTE, which has an investment grade credit rating. The total purchase price for this asset was approximately $45 million.

In October 2018, we reached a preliminary agreement for another expansion of ATN consisting of certain transmission assets in Peru. The assets are currently in operation and will receive dollarized revenues under a long-term contract. Our total investment is expected to be approximately $20 million. The final purchase agreement has not been signed yet.

In January 2019 we entered into an agreement with Abengoa under the Abengoa ROFO Agreement for the acquisition of Befesa Agua Tenes, S.L.U., a holding company which owns a 51% stake of Tenes, a water desalination plant in Algeria, similar in several aspects to our Skikda and Honaine plants. Tenes has a capacity of 7 million cubic feet per day to provide water under a water purchase agreement in place with Sonatrach and ADE (Algerienne des Eaux), with a remaining term of approximately 22 years. It has been in operation since 2015. The tariff structure is based upon plant capacity and water production and price is adjusted monthly based on indexation mechanisms that include local inflation, U.S. inflation and the exchange rate between the U.S. dollar and local currency. Closing of the acquisition is subject to conditions precedent, including the approval by the Algerian administration. At this stage, we cannot guarantee that we will obtain this approval nor the expected timing of such approval. The price agreed for the equity value is $24.5 million, of which $19.9 million was paid in January 2019 as an advanced payment and the rest is expected to be paid once the conditions precedent are fulfilled. If all the conditions precedent were not fulfilled by September 30, 2019, the advanced payment shall be progressively reimbursed by Abengoa through a full cash-sweep of all the dividends to be received and in any case no later than September 30, 2031, together with an annual 12% interest.

Our largest shareholder Algonquin

On November 1, 2017, Algonquin announced that it had reached an agreement with Abengoa to acquire 25.0% of our shares from Abengoa. Along with the 25.0% of our shares Algonquin acquired from Abengoa in November 2017, Algonquin acquired the remaining 16.5% of our shares held by Abengoa on November 27, 2018, bringing its total equity interest in Atlantica up to 41.5%.

In the context of the Algonquin transaction, we signed the Shareholders Agreement with Algonquin, which limits Algonquin’s ownership in us to a maximum of 41.5% of our outstanding shares (with a certain exception where such ownership may be temporarily increased up to 46%) and limits the number of directors they can appoint to a maximum of 50% less one (if the resulting number is not a whole number, it shall be rounded up to the next whole number). In addition, Algonquin has agreed to provide, subject to board approval, incremental equity investment of up to $100 million through the subscription of our ordinary shares for the acquisition of new assets during 2019 and has been granted certain preferred rights when participating in further equity issuances with the possibility of increasing Algonquin’s ownership in us up to 41.5% (and up to 46% in certain cases). Additionally, we have agreed to maintain a target payout ratio of 80%. We agreed with Algonquin to periodically discuss the potential acquisition of assets from Algonquin pursuant to the Algonquin ROFO Agreement. See “Item 7.B— Related Party Transactions.”

We have also signed a ROFO agreement with AAGES, the joint venture created between Algonquin and Abengoa to invest in the development and construction of clean energy and water infrastructure contracted assets. The AAGES ROFO Agreement provides us with a right of first offer on any proposed sale, transfer or other disposition of AAGES ROFO Assets. Some of the assets currently under construction by Abengoa may be transferred to AAGES and the AAGES ROFO Agreement will include such assets within its scope. Additionally, we have entered into a ROFO agreement with Algonquin, which became effective upon completion of the Share Sale, pursuant to which Algonquin has agreed to periodically discuss the possibility of the sale to us of interests in certain assets owned by Algonquin in Canada and the United States and which provides us with a right of first offer on any proposed sale, transfer or other disposition of Algonquin’s assets located outside of the United States and Canada, which are developed under expected long-term revenue agreements or concession agreements. See “Item 7.B—Related Party Transactions.”

B.	Business Overview

Overview

We are a sustainable total return company that owns and manages renewable energy, efficient natural gas, transmission and transportation infrastructures and water assets. We currently have operating facilities in North America (United States and Mexico), South America (Peru, Chile and Uruguay) and EMEA (Spain, Algeria and South Africa). We intend to expand our portfolio, maintaining North America, South America and Europe as our core geographies.

As of the date of this annual report, we own or have an interest in a portfolio of high-quality and diversified assets in terms of type of asset, technology and geographic footprint. Our portfolio consists of 24 assets with 1,496 MW of aggregate renewable energy installed generation capacity, 300 MW of efficient natural gas-fired power generation capacity, 10.5 M ft ³ per day of water desalination and 1,152 miles of electric transmission lines.

All of our assets have contracted revenue (regulated revenue in the case of our Spanish assets and one transmission line in Chile) and are underpinned by long-term contracts. As of December 31, 2018, our assets had a weighted average remaining contract life of approximately 18 years. Most of the assets we own or in which we have an interest have project-finance agreements in place.

We intend to take advantage of, and leverage our growth strategy on, favorable trends in the clean power generation, transmission and transportation infrastructures and water sectors globally, including energy scarcity and the focus on the reduction of carbon emissions. Our portfolio of operating assets and our strategy focuses on sustainable technology including renewable energy, efficient natural gas, and transmission networks as enablers of a sustainable power generation mix and on water infrastructure. Renewable energy is expected to represent in most markets the majority of new investments in the power sector, according to Bloomberg New Energy Finance 2018, approximately 50% of the world’s power generation by 2050 is expected to come from renewable sources, which indicates that renewable energy is becoming mainstream. We believe regions will need to complement investments in renewable energy with investments in efficient natural gas, in transmission networks and in storage. We believe that we are well positioned to benefit from the expected transition towards a more sustainable power generation mix. In addition, we believe that water is going to be the next frontier in a transition towards a more sustainable world. New sources of water are needed worldwide and water desalination and water transportation infrastructure should help make that possible. We currently participate in two water desalination plants with a 10 million cubic feet capacity and we have reached an agreement to acquire a third.

We are focused on high-quality and long-life facilities as well as long-term agreements that we expect will produce stable, long-term cash flows. We intend to grow our cash available for distribution and our dividend to shareholders through organic growth and by acquiring new assets from AAGES, Abengoa, third parties and potential new future partners.

We believe we can achieve organic growth through the optimization of the existing portfolio, price escalation factors in many of our assets and the expansion of current assets, particularly our transmission lines, to which new assets can be connected. We currently own three transmission lines in Peru and four in Chile. We believe that current regulations in Peru and Chile provide a growth opportunity by expanding transmission lines to connect new clients. Additionally, we should have repowering opportunities in certain existing generation assets once their contracted life has expired.

Table of Contents

In addition, we have in place exclusive agreements with AAGES, Algonquin and Abengoa. The AAGES ROFO Agreement provides us with a right of first offer on any proposed sale, transfer or other disposition of certain of AAGES’s assets. The Algonquin ROFO Agreement provides us a right of first offer on any proposed sale, transfer or other disposition of any of Algonquin’s contracted facilities or with infrastructure facilities located outside of the United States or Canada which are developed under expected long-term revenue agreements or concession agreements. Additionally, we plan to collaborate with Algonquin on several co-investment opportunities for assets in operation and for assets under development or construction, and it could represent another source of future growth. In addition, under the Algonquin ROFO Agreement, Algonquin agreed to periodically discuss with us the possibility of offering for sale interests in certain assets owned by Algonquin companies in Canada and the United States. The Abengoa ROFO Agreement provides us with a right of first offer on any proposed sale, transfer or other disposition of any of Abengoa’s contracted renewable energy, efficient natural gas, electric transmission or water assets in operation and located in the United States, Canada, Mexico, Chile, Peru, Uruguay, Brazil, Colombia and the European Union, as well as four assets in selected countries in Africa, the Middle East and Asia. See “Item 4.B—Business Overview—Our Business Strategy” and “Item 7.B—Related Party Transactions—Abengoa Right of First Offer.”

Additionally, we intend to enter into similar agreements or enter into partnerships with other developers or asset owners to acquire assets. We may also invest directly or through investment vehicles with partners in assets under development or construction, ensuring that such investments are always a small part of our total investments. Finally, we also expect to acquire assets from third parties leveraging the local presence and network we have in the geographies and sectors in which we operate.

With this business model, our objective is to pay a consistent and growing cash dividend to shareholders that is sustainable on a long-term basis. We expect to distribute a significant percentage of our cash available for distribution as cash dividends and we will seek to increase such cash dividends over time through organic growth and through the acquisition of assets. Pursuant to our cash dividend policy, we intend to pay a cash dividend each quarter to holders of our shares.

Current Operations

Our portfolio consists of 15 renewable energy assets, a natural gas-fired cogeneration facility, several electric transmission lines and minority stakes in two water desalination plants, all of which are fully operational. We expect that the majority of our cash available for distribution over the next three years will be in U.S. dollars, indexed to the U.S. dollar or in euros. We intend to maintain a ratio of over 80% of our cash available for distribution denominated in U.S. dollars or euros and to hedge the euros for the upcoming 24 months on a rolling basis strategy. As of December 31, 2018, approximately 93% of our project-level debt was hedged against changes in interest rates through an underlying fixed rate on the debt instrument or through interest rate swaps, caps or similar hedging instruments.

Our assets and operations are organized into the following four business sectors:

Renewable Energy

Our renewable energy assets include two solar power plants in the United States, Solana and Mojave, each with a gross capacity of 280 MW and located in Arizona and California, respectively. Solana is a party to a PPA with Arizona Public Service Company and Mojave is a party to a PPA with PG&E. PG&E filed for reorganization under Chapter 11 of the Bankruptcy Code in the U.S., which has caused a default under the PPA agreement with Mojave, which could have a material adverse effect on our business, financial condition, results of operations and cash flow. See “Item 3.D—Risk Factors—Counterparties to our offtake agreements may not fulfill their obligations and, as our contracts expire, we may not be able to replace them with agreements on similar terms in light of increasing competition in the markets in which we operate.”

Additionally, we own or have an interest in the following solar power plants in Spain with a total gross capacity of 682 MW: (i) Solaben 2/3, a 100 MW solar power complex; (ii) Solacor 1/2, a 100 MW solar power complex; (iii) PS10/20, a 31 MW solar power complex; (iv) Helioenergy 1/2, a 100 MW solar power complex; (v) Helios 1/2, a 100 MW solar power complex; (vi) Solnova 1/3/4, a 150 MW solar power complex; (vii) 74.99% of the shares and a 30-year usufruct of the economic rights of the remaining 25.01% of the shares of Solaben 1/6, a 100 MW solar power complex in Spain, which usufruct does not expire until September 2045; and (viii) an 80% stake in Seville PV, a 1 MW solar photovoltaic plant. All such projects receive market and regulated revenues under the economic framework for renewable energy projects in Spain. See “Item 4.B—Business Overview—Regulations.”

We also own 51.0% of Kaxu, a 100 MW solar power plant in South Africa. Kaxu is a party to a 20-year (17 years remaining) PPA with Eskom, the state-owned utility company in South Africa.

We also own three onshore wind farms in Uruguay: Palmatir, Cadonal and Melowind, each with an installed capacity of 50 MW. Each wind farm is subject to a 20-year (15,16 and 17 years remaining, respectively) U.S. dollar-denominated PPA with a state-owned utility company in Uruguay.

Finally, we have an exclusive concession of a 4 MW hydroelectric power plant in Peru pursuant to a 20-year concession agreement (15 years remaining) with the Peruvian Ministry of Energy.

Efficient Natural Gas

Our efficient natural gas asset consists of ACT, a 300 MW cogeneration plant in Mexico. ACT is a party to a 20-year take-or-pay agreement (15 years remaining) with the state-owned company Petróleos Mexicanos, or Pemex, for the sale of electric power and steam. Pemex also supplies the natural gas required for the plant at no cost to ACT, which insulates the project from natural gas price fluctuations.

Electric Transmission

Our electric transmission assets consist of (i) three lines in Peru (ATN, ATN2 and ATS), spanning a total of 1,015 miles and (ii) four lines in Chile (Quadra 1, Quadra 2, Palmucho and Chile TL3), spanning a total of 137 miles.

ATN and ATS are subject to a U.S. dollar-denominated 30-year contract (22 and 25 years remaining, respectively) with the Peruvian Ministry of Energy. ATN2 is subject to a U.S. dollar-denominated 18-year contract (14 years remaining) with Minera Las Bambas mining company, which is owned by a partnership consisting of subsidiaries of China Minmetals Corporation, Guoxin International Investment Co. Ltd and CITIC Metal Co. Ltd. Quadra 1 and Quadra 2 are subject to a contract with 16 years remaining with Sierra Gorda SCM, a mining company owned by Sumitomo Corporation, Sumitomo Metal Mining and KGHM Polska Mietz. Palmucho is a six-mile electric transmission line and substation subject to a contract with 20 years remaining with a utility, Endesa Chile. Finally, Chile TL3 is a 50-mile transmission line that has a tariff under the regulation in place in Chile, denominated in U.S. dollars and indexed to U.S. and Chilean inflation rates.

Water

Our water assets consist of minority stakes in two desalination plants in Algeria, Honaine and Skikda, with an aggregate capacity of 10.5 M ft3 per day. Each asset has a 30-year take-or-pay water purchase agreement (19 and 15 years remaining, respectively) with Sonatrach/Algerienne des Eaux.

Our Business Strategy

Our primary business strategy is to generate stable cash flows through our portfolio of assets under long term contracts or under regulation. We intend to distribute a stable cash dividend to our shareholders. Our objective is to increase the dividend, while ensuring the ongoing stability and sustainability of our business.

Table of Contents

We will seek to grow our cash available for distribution and our dividend to shareholders through organic growth and by acquiring new assets. We believe that our diversification by business sector and geography provides us with access to different sources of growth. We expect to deliver organic growth through the optimization of the existing portfolio and through investments in the expansion of our current assets, particularly in our transmission lines sector. In addition, we expect to acquire assets from AAGES and Abengoa through our existing ROFO agreements. We expect to complement this with acquisitions from third parties and potential new future partnerships. We intend to grow our business in the segments where we are already present, maintaining renewable energy as our main segment and with a focus in North and South America.

Our plan for executing this strategy includes the following key components:

Focus on stable, long-term contracted or regulated assets in the power and water sectors, including renewable energy, efficient natural gas generation and transmission and transportation infrastructures

We intend to focus on owning and operating stable, long-term contracted assets, for which we believe we possess extensive experience and proven systems and management processes, as well as the critical mass to benefit from operating efficiencies and scale. We expect that this will allow us to maximize value and cash flow generation. We intend to maintain a diversified portfolio in the future, as we believe these technologies will undergo significant growth in our targeted geographies.

Maintain geographic diversification across three principal geographic areas

Our focus on three core geographies, North America, South America and Europe, helps to ensure exposure to markets in which we believe the renewable energy, efficient natural gas and transmission and transportation sectors will continue growing significantly.

Increase cash available for distribution through the optimization of the existing portfolio and through the investments in the expansion of our current assets, particularly in our transmission lines, to which new assets can be connected.

We intend to grow our cash available for distribution to shareholders through organic growth that we expect to deliver through the optimization of the existing portfolio , price escalation factors in many of our assets as well as through investments in the expansion of our current assets, particularly in our transmission lines sector. We intend to increase production in our assets through further management and optimization initiatives and in some cases through repowering.

We currently own three transmission lines in Peru and four in Chile. Current regulations in Peru and Chile provide a growth opportunity by expanding transmission lines to connect new clients.

We have identified several opportunities to grow organically in Peru and Chile by expanding our current assets. These opportunities consist of (i) new clients that need to use our current assets, in situations where virtually no investments are required from us, while we will get additional revenues from these new business opportunities and (ii) expansion of current transmission lines to grant access to new clients. In this case, certain investments are required to build new assets that connect the new clients to our current backbone transmission lines. We would expect that in some cases these new assets would become part of our concession assets contract with the State, for which we would be remunerated.

Increase cash available for distribution through the acquisition of new assets in the power and water sectors, including renewable energy, efficient natural gas and transmission and transportation infrastructures

We will seek to grow our cash available for distribution to shareholders by acquiring new assets, typically contracted or regulated. We have an exclusive ROFO agreement with Abengoa and a ROFO agreement with AAGES. We further expect to execute similar agreements with other developers or asset owners or enter into partnerships with such developers or asset owners in order to acquire assets in operation or to invest directly or through investment vehicles in assets under development or construction, ensuring that such investments are always a small part of our total investments. Finally, we expect to acquire assets from third parties leveraging the local presence and network we have in the geographies and sectors where we operate. Additionally, we plan to collaborate with Algonquin on several co-investment opportunities for assets in operation and for assets under development or construction. We believe that our know-how and operating expertise in our key markets together with a critical mass of assets in several geographic areas and the access to capital provided by being a listed company will assist us in realizing our growth plans.

Table of Contents

Foster a low-risk approach

We intend to maintain a portfolio of contracted assets with a low-risk profile for all or part of our revenues by engaging in most cases with creditworthy offtake counterparties and entering into long-term contracted revenue agreements. Over 80% of cash available for distribution is in U.S. dollars or euros, and we hedge euros for the upcoming 24 months on a rolling basis. We further mitigate the risk of our investments by pursuing proven technologies in which we have significant experience, located in countries where we believe conditions to be stable and safe.

In certain situations, we could invest in assets before they enter into operation, in assets with shorter or partially contracted revenue period, or subject to regulation, or in assets with revenue in currencies other than U.S. dollar or euro.

Additionally, our policies and management systems include thorough risk analysis and risk management processes that we apply whenever we acquire an asset, and which we are obligated to review monthly throughout the life of the asset. Our policy is to insure all of our assets whenever economically feasible.

Maintain financial strength and flexibility

We intend to maintain a solid financial position through a combination of cash on hand and undrawn credit facilities. Our conservative cash management is designed to assist us in mitigating any unexpected economic downturns or corporate shortfalls that may reduce our cash flow generation. Our current intention is to maintain a net corporate debt compared to cash available for distribution before corporate interests at or below 3.0x. This is an internal target and not a limit imposed by our agreements with third parties. It is therefore subject to change and we may from time to time exceed this limit temporarily or during prolonged periods of time, for example to finance acquisitions until the time when we obtain long term financing, or otherwise amend our internal target. The foregoing information constitutes a “forward-looking statement.”

Our Competitive Strengths

We believe that we are well-positioned to execute our business strategies because of the following competitive strengths:

Stable and predictable long-term cash flows with attractive tax profiles

We believe that our asset portfolio has a stable, predictable cash flow profile consisting of predominantly long-life electric power generation and electric transmission assets that generate revenues under long-term fixed priced contracts or pursuant to regulated rates. Additionally, our facilities have minimal or no fuel risk. The offtake agreements for our assets have a weighted average remaining duration of approximately 18 years as of December 31, 2018, providing long-term cash flow stability and visibility. For the fiscal year 2018, 54% of our revenues are related to availability payments in the different business sectors in which we operate, which includes our transmission lines, our efficient natural gas plant, our water assets and approximately 70% revenues received by our Spanish solar assets. Furthermore, due to the fact that we are a U.K. resident company, we should benefit from a more favorable treatment than would apply if we were a corporation in the United States when receiving dividends from our subsidiaries that hold our international assets because they should generally be exempt from U.K. taxation due to the U.K.’s distribution exemption. Based on our current portfolio of assets, which include renewable assets that benefit from an accelerated tax depreciation schedule, and current tax regulations in the jurisdictions in which we operate, we do not expect to pay significant income tax in the upcoming years due to existing net operating losses, or NOLs. See “Item 3.D—Risk Factors—Risks Related to Taxation—Our future tax liability may be greater than expected if we do not use NOLs sufficient to offset our taxable income,” “Item 3.D—Risk Factors—Risks Related to Taxation—Our ability to use U.S. NOLs to offset future income may be limited” and “Item 3.D—Risk Factors—Risks Related to Taxation—Changes in our tax position can significantly affect our reported earnings and cash flows.” Furthermore, based on our current portfolio of assets, we believe that there is limited repatriation risk in the jurisdictions in which we operate. See “Item 3.D—Risk Factors—Risks Related to Our Business and the Markets in Which We Operate—We have international operations and investments, including in emerging markets that could be subject to economic, social and political uncertainties.”

Highly diversified portfolio by geography and technology

The renewable energy industry has grown during the recent years and it is expected to continue growing in the next decades. According to Bloomberg New Energy Finance – 2018, approximately 50% of the world’s power generation by 2050 is expected to come from renewable sources, which it is expected to translate into approximately $10 trillion in investments in new zero-emissions power generation assets through 2050. The significant increase expected in the renewable energy space over the next decades also requires significant new investments in electric transmission and distribution lines for power supply, as well as storage and natural gas generation for dispatchability, with each becoming key elements to support wind and solar energy generation.

Against this backdrop of expected growth, we believe that our exposure to international markets will allow us to pursue greater growth opportunities and achieve higher returns than we would if we had a narrow geographic or technological focus. Our portfolio of assets uses technologies that we expect to benefit from these long-term trends in the electricity sector. Our renewable energy generation assets generate low or no emissions and serve markets where we expect growth in demand in the future. Additionally, our electric transmission lines connect electricity systems to key areas in their respective markets and we expect significant electric transmission investment in our geographies. As a result, we believe that we may be able to benefit from opportunities to repower some of our assets during the lives of our existing PPAs and, in some cases, to extend the terms of those contracts after current PPAs expire. We expect our well-diversified portfolio of assets by technology and geography to maintain cash flow stability.

New ownership structure and contractual arrangements with Algonquin support our expectation of a sustainable growth strategy

Algonquin, a North American diversified generation, transmission and distribution utility company and our largest shareholder, owns a 41.5% stake in our capital stock. In addition, Algonquin and Abengoa have created AAGES, a joint venture designed to invest in the development and construction of contracted clean energy and water infrastructure contracted assets.

In the context of these agreements, we have signed a ROFO agreement with AAGES aimed at enhancing our growth opportunities by creating a new platform for the development and construction of contracted clean energy and water infrastructure assets. Additionally, we plan to collaborate with Algonquin on several co-investment opportunities and we believe that it should represent another source of future growth.

In addition, Algonquin has agreed to provide, subject to its board approval, an incremental equity investment of up to $100 million through the subscription of our ordinary shares for the acquisition of new assets during 2019, and has been granted certain preferred rights when participating in further equity issuances with the possibility of increasing Algonquin’s ownership in us from 41.47% to 46% in certain cases. Finally, Algonquin has agreed to periodically discuss the potential sale of North American assets, which continues to be our core geography.

Strong corporate governance with a majority independent board and an experienced management team

Our board of directors has extensive experience in our industry. Five of the eight members of our board of directors are independent from us and from Algonquin. Following the completion of Algonquin’s initial acquisition of a 25% stake in us and the entering into effect of the Shareholders Agreement, Algonquin appointed two directors. Following the completion of Algonquin’s acquisition of the additional 16.5% stake in us, which took place on November 27, 2018, Mr. Gonzalo Urquijo resigned from the board of directors and Mr. Santiago Seage was appointed as a director, while continuing to serve as Chief Executive Officer. Thus, the majority of the board of directors remains independent and Abengoa no longer as the right to appoint any directors to the board . In addition, we require a majority vote by our independent directors in connection with related party transactions, including acquisitions under the AAGES ROFO Agreement and the Algonquin ROFO Agreement. Our management team has significant and valuable expertise in developing, financing, operating and managing renewable energy, efficient natural gas and electric transmission assets. We believe their industry knowledge and management skills will help us achieve our financial targets and continue to assist us in growing on a cash accretive basis over the medium- to long-term.

Solana

Overview . The Solana Solar plant, or Solana, is a 250 MW net (280 MW gross) solar electric generation facility located in Maricopa County, Arizona, approximately 70 miles southwest of Phoenix, Arizona Solar One LLC, or Arizona Solar, owns the Solana project. Solana includes a 22-mile 230kV transmission line and a molten salt thermal energy storage system. The construction of Solana commenced in December 2010 and Solana reached COD on October 9, 2013.

Solana relies on a conventional parabolic trough solar power system to generate electricity. The parabolic trough technology has been used for over 25 years at the Solar Electric Generating Systems (SEGS) facilities located in the Mojave Desert in Southern California. Our thirteen 50 MW parabolic trough facilities in Spain have also used this technology since 2010. Solana produces electricity by means of an integrated process using solar energy to heat a synthetic petroleum-based fluid in a closed-loop system that, in turn, heats water to create steam to drive a conventional steam turbine. Solana employs a two-tank molten salt thermal energy storage system that provides an additional six hours of solar dispatchability to increase its efficiency.

Power Purchase Agreement . Solana has a 30-year, fixed-price PPA with Arizona Public Service Company, or APS, for at least 110% of the output of the project. The PPA provides for the sale of electricity at a fixed base price approved by the Arizona Corporation Commission with annual increases of 1.84% per year. The PPA includes on-going performance obligations and is intended to provide Arizona Solar with consistent and predictable monthly revenues that are sufficient to cover operating costs and debt service and to earn an equity return.

EPC Agreements . The construction of Solana was carried out by subsidiaries of Abengoa under an arm’s-length, fixed-price and date-certain EPC contract, that was executed on December 20, 2010. Abengoa completed construction of Solana on October 9, 2013.

Arizona Solar’s EPC contract contains warranties that protect Arizona Solar against defects in design, materials and workmanship for one year after completion and under these warranties Abengoa is required to conduct certain repairs and improvements to ensure the plant reaches its technical capacity. Solana has not yet achieved its technical capacity on a continuous basis. During the last few years and into 2019, repairs and improvements were and will be conducted on three plant systems: the steam generator, the water plant and the storage heat exchangers. In July 2016, the solar field was damaged after a severe wind event and in 2017, we received insurance compensation for damages and loss of revenue. In July 2017, there was an incident with electric transformers, which caused the plant to produce at a reduced capacity during July and part of August. All the necessary repairs were completed in August and we received a significant portion of the insurance compensation in 2017. In addition, Solana experienced technical issues in the heat exchangers within its storage system. Repairs have been carried out in the past years. In 2018 Abengoa and the supplier of the heat exchangers presented a proposal to improve the performance and reliability of this equipment which has been implemented progressively in 2018 and 2019. In addition, we plan to replace one of the heat exchangers in 2019. In addition, we are currently purchasing an additional heat exchanger which is expected to be kept as a backup in case of a failure of any of the others. We cannot assure that the repairs, improvements and replacements made or currently underway will be effective or sufficient.

Table of Contents

In November 2017, in the context of the agreement reached between Abengoa and Algonquin for the initial acquisition by Algonquin of 25.0% of our shares and based on the obligations of Abengoa under an EPC contract, the DOE signed a consent in relation to the Solana and Mojave projects which reduced the minimum ownership required by Abengoa in us from 30.0% to 16.0%. Solana received an aggregate amount of $120 million in payments from Abengoa ($42.5 million in December 2017 and $77.5 million in March 2018). Of the received sums, $95 million was used to repay project debt and $25 million was set aside to cover other Abengoa obligations. In addition, in November 2018 in the context of the DOE consent to allow Abengoa to sell entirely its stake in Atlantica, Solana received $16.5 million, of which $9 million was used to repay project debt and $7.5 million were set aside to cover potential repairs and other Abengoa obligations. Additionally, the long-term payments schedule signed between Abengoa and Solana was amended to include $7.4 million payable semi-annually over 2 years and $10.3 million payable semi-annually over the subsequent 4 years, beginning in January 2019. Solana also received a parcel of land adjacent to the Solana site accounted for at a fair value of $7.3 million. Furthermore, Abengoa agreed to pay $13 million to fund a reserve account progressively in 2020 and 2021. If Abengoa were not to make these payments, we would need to make them and in return we would reduce future bonus payments to Abengoa under certain operation and maintenance agreements. The aforementioned amounts result of Abengoa’s obligations as EPC contractor. Likewise, in November 2018, and after satisfying all conditions precedent to completion, the DOE signed a consent in relation to the Solana and Mojave projects for the sale of the remaining Abengoa’s 16.47% interest in us to Algonquin. The Share Sale was completed on November 27, 2018.

O&M . ASI Operations, a wholly-owned subsidiary of Abengoa, provides O&M services for Solana, focused exclusively on providing personnel. ASI Operations has agreed to operate the facility in accordance with prudent industry practices, to ensure compliance with all applicable government and agency permits, licenses, approvals and PPA terms, and to assist Arizona Solar in connection with the procurement of all necessary support and ancillary services. The O&M agreement, executed on December 20, 2010 between ASI Operations and Arizona Solar is a 30-year cost-reimbursable contract plus a fixed fee, which is indexed to U.S. CPI. A variable fee is to be paid in periods when the project’s annual net operating profits exceed the target annual net operating profit. Payments to third-party suppliers are made directly by Arizona Solar. We expect that the variable fee will provide ASI Operations with a significant long-term interest in the success of the project, which we expect will align its interests with those of Arizona Solar.

Project Level Financing . Arizona Solar executed a loan guarantee agreement with the DOE on December 20, 2010, to provide a loan guarantee in connection with a two-tranche loan of approximately $1.445 billion from the FFB. The short-term tranche of $450 million has been repaid. The long-term tranche is payable over a 29-year term with the cash generated by the project. The principal balance of this tranche was $810 million as of December 31, 2018.

The FFB loan permits dividend distributions on a semi-annual basis as long as the debt service coverage ratio for the previous four fiscal quarters is at least 1.20x after December 31, 2019 (1.30x debt service coverage ratio and operating performance above certain thresholds for distributions before December 31, 2019) and the projected debt service coverage ratio for the next four fiscal quarters is at least 1.20x. As of December 31, 2018, Solana met the minimum debt service coverage ratio, however it did not meet the operating and performance thresholds for distributions. The asset may or may not meet those thresholds in 2019.

Partnerships . On September 30, 2013, Abengoa entered into an agreement with Liberty, pursuant to which Liberty agreed to invest $300 million for all of the Class A membership interests of ASO Holdings Company LLC, the parent of Arizona Solar, giving Liberty the right to receive 61.20% of ASO Holdings Company LLC’s taxable losses and distributions until such time as Liberty reaches a certain rate of return, or the Flip Date. Given that Solana has not performed as expected, Liberty will require additional distributions in order to reach the agreed rate of return. The distributions in the upcoming years will depend on the performance of Solana and we expect them to go mostly or entirely to Liberty. After the Flip Date, Liberty will be entitled to receive 22.60% of taxable losses and distributions. In 2017, we agreed with Liberty to increase their information rights and their participation in decisions with respect to Arizona Solar. All figures in this annual report take into account Liberty’s share of dividends. We indirectly own 100% of the Class B membership interests in ASO Holdings Company LLC.

Mojave

Overview . The Mojave Solar Project, or Mojave, is a 250 MW net (280 MW gross) solar electric generation facility wholly-owned by us located in San Bernardino County, California, approximately 100 miles northeast of Los Angeles. Abengoa commenced construction of Mojave in September 2011. Mojave completed construction and reached COD on December 1, 2014. Mojave Solar LLC, or Mojave Solar, owns the Mojave project.

Table of Contents

Mojave relies on a conventional parabolic trough solar power system to generate electricity and is similar to Solana with respect to technology and general design. The main difference between Solana and Mojave is that Mojave does not have a molten salt storage system, as the offtaker did not require one.

PPA . Mojave has a 25-year, fixed-price PPA with Pacific Gas & Electric Company, or PG&E, for 100% of the output of Mojave. The PPA began on COD. The PPA provides for the sale of electricity at a fixed base price with seasonal adjustments and adjustments for time of delivery. Mojave Solar can deliver and receive payment for at least 110% of contracted capacity under the PPA.

On January 29, 2019, PG&E, the off-taker for Atlantica Yield with respect to the Mojave plant, filed for reorganization under Chapter 11 of the Bankruptcy Code in the U.S. Bankruptcy Court for the Northern District of California. See “Item 3.D—Risk Factors— Counterparties to our offtake agreements may not fulfill their obligations and, as our contracts expire, we may not be able to replace them with agreements on similar terms in light of increasing competition in the markets in which we operate.”

EPC Agreement . The construction of Mojave was carried out by subsidiaries of Abengoa, under an arm’s-length, fixed-price EPC contract that was executed on September 12, 2010. Mojave reached COD on December 1, 2014. Mojave’s key equipment has been supplied by leading companies, including two twin turbines from General Electric.

O&M . ASI Operations provides O&M services for Mojave focused exclusively on personnel. Under the terms of the O&M agreement between ASI Operations and Mojave Solar, ASI Operations has agreed to operate the facility in accordance with prudent industry practices, to ensure compliance with all applicable government and agency permits, licenses, approvals and PPA terms, and to assist Mojave Solar in connection with the procurement of all necessary support and ancillary services. The O&M agreement is a cost-reimbursable contract plus a combination of fixed and variable fees. Payments to third-party suppliers are made directly by Mojave Solar. Mojave Solar pays the variable fee in periods when the project’s annual net operating profits exceed the target annual net operating profit. We expect that the variable fee will provide ASI Operations with a significant long-term interest in the success of the project, which we expect will align its interests with those of Mojave Solar.

Project Level Financing . Mojave Solar executed a loan guarantee agreement with the DOE on September 12, 2011, to provide a loan guarantee in connection with a two-tranche FFB loan of approximately $1,202 million. The short-term tranche has been repaid. The long-term tranche is payable over a 25-year term with the cash generated by the project. The principal balance of this tranche was $739 million as of December 31, 2018. The FFB loan has an average fixed interest rate of 2.75% and each disbursement is linked to the U.S. Treasury bond with the maturity of that disbursement. A breach of the PPA agreement with PG&E occurred with the PG&E bankruptcy filing and such breach could trigger an event of default under our Mojave project finance agreement if certain other conditions were met, namely if (i) such breach or default could reasonably be expected to result in a material adverse effect to Mojave or (ii) PG&E failed to assume the PPA within 60 days, extendable to 180 days provided that PG&E continues to perform under the PPA. See “Item 3.D—Risk Factors— Counterparties to our offtake agreements may not fulfill their obligations and, as our contracts expire, we may not be able to replace them with agreements on similar terms in light of increasing competition in the markets in which we operate.”

The financing arrangement permits dividend distributions on a semi-annual basis after the first principal repayment of the long-term tranche, as long as the debt service coverage ratio for the previous four fiscal quarters is at least 1.20x and the projected debt service coverage ratio for the next four fiscal quarters is at least 1.20x.

Solaben 2/3

Overview . The Solaben 2 and Solaben 3 projects are two 50 MW solar power plants located in the municipality of Logrosan, Spain. Solaben 2 reached COD in 2012 and Solaben 3 reached COD in 2012.

Solaben 2 and Solaben 3 each rely on a conventional parabolic trough solar power system to generate electricity. The technology is similar to the technology used in other solar power plants that we own in the United States and in other locations in Spain.

Regulation. Renewable energy projects in Spain sell the power they produce into the wholesale electricity market and receive additional payments from the Comision Nacional de los Mercados y de la Competencia, or CNMC, the Spanish state-owned regulator.

Solar power plants receive, in addition to the revenues from the sale of electricity in the market, two monthly payments. These payments consist of: (i) a fixed monthly payment based on installed capacity, and (ii) a variable payment based on net electricity produced. There is a maximum number of production hours per year beyond which no variable payment is received. The regulation also includes a minimum number of yearly hours of generation, under which the plant would receive no regulated payments for that year and another higher threshold below which regulated payments would be reduced for a certain year. Those numbers are 35.0% and 60.0% of the maximum yearly hours, respectively. We expect that a plant would fail to achieve these thresholds only in cases of major breakdowns. See “—Regulation—Regulation in Spain.”

Spain has senior unsecured credit ratings of A- from S&P, Baa1 from Moody’s and A- from Fitch.

O&M . ASE is the contractor for O&M services at Solaben 2/3. ASE has agreed to operate the facility in accordance with prudent industry practices, ensure compliance with all applicable government and agency permits, licenses and approvals, and feed-in tariff terms, and to assist Solaben 2/3 in connection with the procurement of all necessary support and ancillary services. Each O&M agreement is an all-in contract that we could terminate every third year starting in December 2015.

Project Level Financing . On December 16, 2010, Solaben 2 and Solaben 3 each entered into a 20-year loan agreement with a syndicate of banks formed by the MUFG, Mizuho, HSBC and Sumitomo Mitsui Banking Corporation. The loan for Solaben 2 was for €169.3 million and the loan for Solaben 3 was for €171.5 million. The banks providing these loans obtained commercial and political risk insurance from Nippon Export and Investment Insurance, which allowed for lower financing costs. The interest rate for each loan is a floating rate based on EURIBOR plus a margin of 1.5%. We initially hedged 80% of our EURIBOR exposure with the same banks providing the financing. The hedge was structured 50% through a swap set at approximately 3.7% and 50% through a cap with a 3.75% strike. In November 2013, SE2 and SE3 hedged the remaining 20% exposure through a cap with a 0.75% strike through 2017. Furthermore, in 2017, we contracted additional caps with a 1% strike covering 19.1% of the principal of Solaben 2 and 20% of the principal of Solaben 3. Both caps hedge the interest rate from the middle of 2017 through 2025.

The outstanding amount of these loans as of December 31, 2018 was €129 million for Solaben 2 and €132 million for Solaben 3.

The financing arrangements permit cash distribution to shareholders twice per year if the audited financials for the prior fiscal year indicate a debt service coverage ratio of at least 1.10x.

Helios 1/2

Overview . The Helios 1/2 project is a 100 MW concentrating solar power facility wholly owned by us located in the municipality of Arenas de San Juan, Puerto Lapice and Villarta de San Juan, Spain. Helios 1 and Helios 2 reached COD in 2012. We indirectly own 100% of Helios 1/2.

Helios 1/2 relies on a conventional parabolic trough concentrating solar power system to generate electricity. This technology is similar to the technology used in other solar power plants that we own in other locations in Spain.

Helios 1/2 benefits from the tax accelerated depreciation regime established by the Spanish Corporate Income Tax Act applicable to the tax consolidated group into which the plants are included.

Regulation. Renewable energy projects in Spain sell the power they produce into the wholesale electricity market and receive additional payments from CNMC. See Solaben 2/3 above and “—Regulation—Regulation in Spain.”

Spain has senior unsecured credit ratings of A- from S&P, Baa1 from Moody’s and A- from Fitch.

O&M . ASE is the contractor for O&M services at Helios 1/2. ASE has agreed to operate the facility in accordance with prudent utility practices, ensure compliance with all applicable government and agency permits, licenses and approvals, and feed-in tariff terms, as well as to assist Helios 1/2 in connection with the procurement of all necessary support and ancillary services. The O&M agreement is an all-in contract that expires on the 25th anniversary of the COD.

Project Level Financing . On May 17, 2018 we refinanced Helios 1/2 as expected in our financial plan. Under the previous financing, Helios 1/2 projects had a “cash-sweep” mechanism in the financing agreements in virtue of which all the cash generated by the projects, from 2020 onwards had to be used to prepay the outstanding loan amounts. The new loan agreements have eliminated this requirement.

The new project finances are two mini-perm loan agreements for a total amount of €292 million for both projects with a syndicate of eight banks formed by Santander S.A., Caixabank S.A., Bankia S.A., ICO, Credit Agricole Corporate, ING Bank N.V., Abanca S.A. and Bankinter S.A. The increase in notional with respect to the previous financing was used to partially cancel the swap in place and pay refinancing costs. The mini-perm structure consists of sculpting semiannual debt service payments using an underlying tenor of 15 years but with a contractual legal maturity in 2027. We expect to refinance Helios 1/2 before 2028. The interest rate for the loans is a floating rate based on EURIBOR (six months) plus a margin of: (i) 2.25% until December 2020; (ii) 2.50% from January 2021 until December 2024; (iii) 2.75% from January 2025 until maturity.

The loans are currently 70% hedged with swaps with some of the same banks providing the financing. We have maintained part of the swaps which were previously in place. As a result, 64% of the swap hedged portion is structured through a swap set at approximately 3.85% and 36% through a new swap contracted in 2018 set at approximately 0.89%. Furthermore, in 2017, we contracted additional caps with a 1% strike covering 11% of the principal of both loan agreements through 2025. The outstanding amount of the loans as of December 31, 2018 was €237 million.

The financing agreements of both plants permit cash distributions to shareholders twice per year from 2019 onwards if the debt service coverage ratio is at least 1.15x.

Kaxu

Overview . Kaxu Solar One Solar, or Kaxu, is a 100 MW net solar conventional parabolic trough project with a molten salt thermal energy storage system and is located in Pofadder, Northern Cape Province, South Africa. We, through ABY Solar South Africa (Pty) Ltd, own 51% of the Kaxu project. The project company, Kaxu Solar One (Pty) Ltd., is currently owned by: us (51%), Industrial Development Corporation of South Africa (29%) and Kaxu Community Trust (20%). The project reached COD in January 2015.

Kaxu relies on a conventional parabolic trough solar power system to generate electricity. This technology is similar to the technology used in solar power plants that we own in Spain.

PPA . Kaxu has a 20-year PPA with Eskom, under a take–or-pay contract for the purchase of electricity up to the contracted capacity from the facility. The PPA expires in February 2035. Eskom purchases all the output of the Kaxu plant under a fixed-price formula in South African Rand subject to indexation to local inflation.

Eskom is a state-owned, limited liability company, wholly owned by the government of the Republic of South Africa. Eskom’s payment guarantees are underwritten by the South African Department of Energy, under the terms of an implementation agreement. Eskom’s credit ratings have recently worsened and is currently CCC+ from S&P, B2 from Moody’s and BB- from Fitch. The Republic of South Africa’s credit ratings are currently BB from S&P, Baa3 from Moody’s and BB+ from Fitch.

EPC Agreement . Certain Abengoa subsidiaries carried out the construction of Kaxu under an arm’s-length, fixed-price and date-certain engineering, procurement and construction contract. In December 2016, two water pumps failed, temporarily limiting the plant’s production until repaired. During 2017, we carried out repairs on the water pumps and the heat exchangers in the storage system. The insurance claim for repairs and loss of production of the water pumps was collected in the second quarter of 2017.

In Kaxu, the EPC contract provided a performance guarantee of 12 consecutive and uninterrupted months within the initial 24-month period, for the benefit of the project company and the financing parties. In Kaxu, we reached an agreement with Abengoa as EPC supplier and the lenders under the project financing agreement to extend the production guarantee until October 2018. In the extended period, Kaxu reached the main target production parameters but not all of them, which resulted in obligations and guarantees of approximately $2 million. Kaxu’s dividend distributions to the holding company level are subject to a number of conditions, including the asset reaching formal completion and Abengoa fulfilling the previous obligations as EPC supplier. In exchange for that extension, Abengoa agreed to perform certain technical improvements in the heat exchangers and committed to provide an approximately $15 million letter of credit to guarantee the correct performance of those heat exchangers in the upcoming 5 years.

O&M . Kaxu entered into an O&M agreement with Kaxu CSP O&M Company, a company owned by a subsidiary of Abengoa Solar (92%) and Kaxu Black Employee Trust, (8%) for the operation and maintenance of the project. The O&M agreement is for a period of 20 years from COD (expiring in 2035). The operator operates the facility in accordance with prudent utility practices, to ensure compliance with all applicable government and agency permits, licenses, approvals and PPA terms, and to assist Kaxu with the procurement of necessary support and ancillary services.

Table of Contents

Project Level Financing . Kaxu entered into a long-term financing agreement with a lenders’ group including Nedbank and RMB, Industrial Development Corporation of South Africa and Development Bank of Southern Africa, and the International Finance Corporation for a total approximate amount of ZAR 5,860.0 million. The loan consists of senior and subordinated long-term loans payable in South African rand over an 18-year term with the cash generated by the project. The interest rate exposure was initially 100% hedged through a swap with the same banks providing the financing, and the coverage progressively reduces over the life of the loan with a current effective annual interest rate of 11.44%.

As of December 31, 2018, the outstanding amount of these loans was ZAR 5,531 million, or approximately $385 million.

The financing arrangement permits dividend distributions on a semi-annual basis after the first repayment of debt has occurred, as long as the historical and projected debt service coverage ratios are at least 1.2x. In 2017, Kaxu’s debt coverage ratio did not reach the minimum threshold due to the technical problems that the plant experienced since the end of 2016. In 2018, although Kaxu’s debt coverage reached the minimum threshold, distributions were delayed as a consequence of the planned finalization of the guarantee period in late 2018.

Exchangeable Preferred Equity Investment in Abengoa Concessões Brasil Holding

In addition to the assets listed above, from our IPO until 2017 we held an exchangeable preferred equity investment in ACBH, a subsidiary holding company of Abengoa engaged in the development, construction, investment and management of contracted concessions in Brazil, comprised mostly of transmission lines, some of which were in operation and some of which were under construction.

Table of Contents

On January 29, 2016, Abengoa informed us that several of its indirect subsidiaries of Abengoa in Brazil, including ACBH, had initiated an insolvency procedure under Brazilian law (“ reorganizaçao judiciaria ”), as a joint processing request (“ pedido de processamento conjunto ”) which resulted in the consolidation of the three main subsidiaries of Abengoa in Brazil, including ACBH. In April 2016, Abengoa presented a consolidated restructuring plan in the Brazilian Court which included ACBH and two other subsidiaries. In 2016, we did not receive any preferred dividend from ACBH. Under the contracts referred to above, we retained dividends payable to Abengoa in 2016 and 2017.

In the third quarter of 2016, we signed an agreement with Abengoa relating to, inter alia, the ACBH preferred equity investment. The key terms of the agreement included the following:

•

Abengoa acknowledged it failed to fulfill its obligations under the agreements related to the preferred equity investment in ACBH and, as a result, we were recognized as the legal owner of the dividends that we retained from Abengoa totaling $10.4 million in 2017, $19.0 million in 2016 and $9.0 million in the fourth quarter of 2015.

•

Abengoa recognized a non-contingent credit corresponding to the guarantee provided by Abengoa regarding the preferred equity investment in ACBH, subject to restructuring. Subject to implementation of the restructuring, we agreed to receive 30% of the amount in the form of tradable notes to be issued by Abengoa (the “Restructured Debt”). The remaining 70% was agreed to be received in the form of equity in Abengoa.

•

The Restructured Debt was converted into senior status following our participation in Abengoa’s issuance of asset-backed notes or New Money 1 Tradable Notes. We subsequently sold New Money 1 Tradable Notes in early April 2017.

•

On the basis that we had received the Restructured Debt and Abengoa equity, we waived our rights under the ACBH agreements, including our right to further retain dividends payable to Abengoa. As a result, in March 2017, we wrote off the accounting value of the ACBH instrument, equal to $30.5 million as of December 31, 2016. We sold all the debt and equity instruments we received from Abengoa and we do not expect any additional value from the ACBH preferred equity investment. We no longer own any shares in ACBH.

Honaine has a corporate income tax exemption until 2021. After that period, in case the exemption is not extended, a claim may be made under the water purchase agreement for compensation in the tariff.

Concessions Agreement . The water purchase agreement is a U.S. dollar indexed 30-year take-or-pay contract with Sonatrach/Algerienne des Eaux, or ADE, from the date of execution, or 25-year term from COD. The tariff structure is based upon plant capacity and water production, covering variable cost (water cost plus electricity cost). Tariffs are adjusted monthly based on the indexation mechanisms that include local inflation, U.S. inflation and the exchange rate between the U.S. dollar and local currency.

Operations & Maintenance . In May 2007, MBH signed an operation and maintenance contract and a membrane and chemical products supply contract with UTE Desaladora Honaine Operacion y Mantenimiento (a joint venture between Abengoa Water, S.L. and Sacyr, S.A., each holding 50%).

The O&M agreement is a 30-year contract from the date of execution (or 25-year term from COD) with a fixed fee and a variable component. The fixed O&M cost covers mainly structural and staff costs. The variable O&M cost covers the chemical products, filters cost and membranes costs related to the water production.

Project Level Financing . In May 2007, MBH signed a financing agreement (as amended in November 2008 and June 2013) with Credit Populaire d’Algerie. The final amount of the loan was $233 million and it accrues fixed-rate interest of 3.75%. The repayment of the Honaine facility agreement consists of sixty quarterly payments, ending in April 2027.

The financing arrangements permit cash distribution to shareholders once per year under certain conditions, including that the audited financials for the prior fiscal year indicate a debt service coverage ratio of at least 1.25x.

Partnerships . 51% of the plant is owned by Geida Tlemcen, which is jointly owned by us (50%) and Valoriza Agua, S.L.U., (50%). The other 49% is held by AEC.

Skikda

Overview . On February 3, 2015, we completed the acquisition of 34.2% of Skikda pursuant to the Abengoa ROFO Agreement.

The Skikda project is a water desalination plant located in Skikda, Algeria. Skikda is located 510 km east of Algiers. Aguas de Skikda, or ADS, is the vehicle incorporated in Algeria for the purposes of owning the Skikda project. AEC owns 49% and Valoriza Agua, S.L.U., subsidiary of Sacyr S.A., owns the remaining 16.83% of the Skikda project.

The technology used in the Skikda plant is currently the most commonly used in this kind of project. It consists of the use of membranes to obtain desalinated water by reverse osmosis. Skikda has a capacity of 3.5 M ft3 per day of desalinated water and has been in operation since May 2009. The project serves a population of 0.5 million.

Skikda has a corporate income tax exemption until 2019. After that period, in case the exemption is not extended, a claim may be made under the water purchase agreement for compensation in the tariff.

Our Growth Strategy

We intend to grow our cash available for distribution and our dividend to shareholders through:

organic growth through the optimization of the existing portfolio, investments in the expansion of our current assets, particularly in our transmission lines sector, and the repowering of our current generation assets;

acquiring new contracted revenue-generating assets in operation from AAGES, Algonquin and Abengoa under our current ROFO agreements;

potential new future partnerships we plan to sign agreements or enter into partnerships with other developers or asset owners in order to acquire assets in operation or to invest directly or through investment vehicles in assets under development, ensuring that such investments are always a small part of our total investments.; and

acquisitions of assets from third parties.

In general, we expect to acquire assets that are developed and operational. We also might make investments in assets that are under development or construction. We also might acquire assets or businesses where revenues are not contracted.

We intend to use the following investment guidelines in evaluating prospective acquisitions in order to successfully execute our growth strategy:

high quality offtakers or regulation, with long-term contracted revenue;

project financing in place at each project or mechanisms to obtain it at COD;

management and operational systems and processes at an adequate level;

focus on regions and countries that provide an optimal balance between growth opportunities and security and risk considerations, including the United States, Canada, Mexico, Chile, Peru, Uruguay, Colombia and the European Union; and

preference for U.S. dollar-denominated revenues, but we could also acquire assets or business that generate revenues in other currencies.

Acquisitions

Historical acquisitions

Following our IPO in 2014, we completed a series of four dropdown asset acquisitions with Abengoa, which formed the basis for our asset portfolio including Solacor 1/2, PS 10/20, Cadonal, Honaine, Skikda, Helioenergy 1/2, Helios 1/2, Solnova 1/3/4, Kaxu, ATN2 and Solaben 1/6. In 2016 and 2017, we acquired a stake in Seville PV and a transmission line in the United States from Abengoa.

2018 acquisitions

Table of Contents

Customers and Contracts

We derive our revenue from selling electricity, electric transmission capacity and desalination capacity. Our customers are mainly comprised of governments and electrical utilities, the latter with which we typically have entered into PPAs. We also employ concession contracts, typically ranging from 20 to 30 years. See the description of each asset under “—Our Operations” for more detail on each concession contract.

Table of Contents

Our main contracts in our business also include the project finance contracts with banks or financial institutions and the operation and maintenance contracts of each of our assets. See description of financing and operation and maintenance contracts under “—Our Operations.”

Additionally, we have entered into a ROFO agreement, a Financial Support Agreement and other agreements with Abengoa as well as a ROFO agreement with both AAGES and Algonquin. See “Item 7.B - Related Party Transactions” for more detail on these contracts.

Competition

Renewable energy, efficient natural gas and electric transmission are all capital-intensive and commodity-driven businesses with numerous industry participants. We compete based on the location of our assets in various countries and regions; however, because our assets typically have 20- to 30-year contracts, competition with other asset operations is limited with respect to existing assets until the expiration of the PPAs. Power generation and transmission are highly regulated businesses in each country in which we operate and are currently highly fragmented and have a diverse industry structure. Our competitors have a wide variety of capabilities and resources. Our competitors include, among others, regulated utilities and transmission companies, other independent power producers and power marketers or trading companies and state-owned monopolies.

Intellectual Property

In general, the construction or other agreements in each asset allow us to use the technology and intellectual property of suppliers. We own the Atlantica Yield name and the www.atlanticayield.com domain. The website address is a textual reference only, meaning that the information contained on our website is not a part of, and is not incorporated by reference in this Annual Report.

Regulatory and Environmental Matters

See “Item 4.B—Business Overview—Regulation.”

Insurance

We maintain the types and amounts of insurance coverage that we believe are consistent with customary industry practices in the jurisdictions in which we operate. Our insurance policies cover employee-related accidents and injuries, property damage, machinery breakdowns, fixed assets, facilities and liability deriving from our activities, including environmental liability. We maintain business interruption insurance for interruptions resulting from incidents covered by insurance policies, with a customary deductible period. Our insurance policies also cover directors’ and officers’ liability and third-party insurance. We cannot assure you, however, that our insurance coverage will adequately protect us from all risks that may arise or in amounts sufficient to prevent any material loss or that premiums will not increase in the future and that insurers will not change the terms of the policies in the future, including changes in deductible costs and periods. See “Item 3.D — Risk Factors—Risks Related to Our Business and the Markets in Which We Operate—Our insurance may be insufficient to cover relevant risks or the cost of our insurance may increase.”

Seasonality

Our operating results and cash flows can be significantly affected by weather in some of our most relevant projects, such as the solar power plants. We expect to derive a majority of our annual revenues in the months of May through September, when solar generation is the highest in the majority of our markets and when some of our offtake arrangements provide for higher payments to us.

Environment and Sustainability

Environmental management is a key priority in our business and operations. Our facilities and operations are subject to significant government regulation, including stringent and comprehensive federal, provincial and local laws, statutes, regulations, guidelines, policies, directives and other requirements governing or relating to, among other things: air emissions; discharges into water; storage, handling, use, disposal, transportation and distribution of dangerous materials and hazardous, residual and other regulated materials, such as chemicals; the prevention of releases of hazardous materials into the environment; the presence and remediation of hazardous materials in soil and groundwater, both on and offsite; the protection of natural resources; land use and zoning matters; and workers’ health and safety matters. We consider environmental protection as an area of performance and as such, environmental issues are included among the responsibilities of our key executives.

Employees and Human Resources

As of the date of this Annual Report, we had 217 employees (including both operations and maintenance and general and administrative staff). None of our employees are unionized. We have not experienced any strikes or work stoppages in our workforce.

Safety and Maintenance

We implement and follow the industry safety standards in the countries where we operate in the interest of the safety of our employees and contractors and the communities where our operations are located. In terms of operational efficiency, we focus on ensuring long-term availability, reliability and asset integrity with maintenance and monitoring.

We carefully selected the suppliers of our solar panels, turbines, windmills, transmission towers and equipment through a detailed evaluation process, focusing on their commercial track record and regular availability of components and replacement parts for the proper functioning and maintenance of our assets and facilities.

Legal Proceedings

On October 17, 2016, ACT received a request for arbitration from the International Court of Arbitration of the International Chamber of Commerce presented by Pemex. Pemex requested compensation for damages caused by a fire that occurred in their facilities during the construction of the ACT cogeneration plant in December 2012, for a total amount of approximately $20 million. On July 5, 2017, Seguros Inbursa, the insurer of Pemex, joined as a second claimant in the process. In September 2018, ACT was notified that an agreement had been reached between insurance companies according to which ACT would not have to pay any amount in relation to this arbitration. On December 19, 2018 the parties to the arbitration executed a settlement agreement to finalize the claim without any financial impact to ACT.

A number of Abengoa’s subcontractors and insurance companies that issued bonds covering Abengoa’s obligations under such contracts in the United States included some of the non-recourse subsidiaries of the Company in the United States as co-defendants in claims against Abengoa. Generally, the subsidiaries of the Company have been dismissed as defendants at early stages of the processes but there remain pending cases including by Arb Inc. with a potential total claim of approximately $33 million and by a group of insurance companies against a number of Abengoa’s subsidiaries and to Solana (Arizona Solar One) a potential claim for Abengoa related losses of approximately $20 million that could increase, according to the insurance companies, up to a maximum of up to approximately $200 million if all their exposure resulted in losses. The Company reached an agreement with Arb Inc. and all but one of the above-mentioned insurance companies, under which they agreed to dismiss their claims in exchange for payments of approximately $6.6 million, which were made in 2018. The insurance company which did not join the agreement has temporarily stopped legal actions against the Company and the Company does not expect any further action to have a material adverse effect.

Table of Contents

In addition, an insurance company covering certain Abengoa’s obligations in Mexico has claimed certain amounts related to a potential loss. This claim is covered by existing indemnities from Abengoa. Nevertheless, the Company has reached an agreement under which Atlantica´s maximum theoretical exposure would in any case be limited to approximately $35 million, including $2.5 million to be held in an escrow account. In January 2019, the insurance company executed $2.5 million from the escrow account and Abengoa reimbursed such amount according to the existing indemnities in force between Atlantica and Abengoa . The payments by us would only happen if and when the actual loss has been confirmed, Abengoa has not fulfilled their obligations and after arbitration, if the Company initiates such arbitration.

The Company is not a party to any other significant legal proceeding other than legal proceedings arising in the ordinary course of its business. The Company is party to various administrative and regulatory proceedings that have arisen in the ordinary course of business. While the Company does not expect these proceedings, either individually or in the aggregate, to have a material adverse effect on its financial position or results of operations, because of the nature of these proceedings the Company is not able to predict their ultimate outcomes, some of which may be unfavorable to the Company.

Regulation

Overview

We operate in a significant number of highly regulated markets. The degree of regulation to which our activities are subject varies by country. In a number of the countries in which we operate, regulation is carried out mainly by national regulatory authorities. In others, such as the United States and, to a certain degree, Spain, there are various additional layers of regulation at the state, regional and/or local level. In countries with these additional layers of regulatory agencies, the scope, nature and extent of regulation may differ among the various states, regions and/or localities.

While we believe the requisite authorizations, permits and approvals for our assets have been obtained and that our activities are operated in substantial compliance with applicable laws and regulations, we remain subject to a varied and complex body of laws and regulations that both public officials and private parties may seek to enforce. The following is a description of the primary industry-related regulations applicable to our assets that are currently in force in the principal markets in which we operate.

Regulation in the United States

In the United States, our electricity generation project companies are subject to extensive federal, state and local laws and regulations that govern the development, ownership, business organization and operation of power generation facilities. The federal government regulates wholesale sales, operation and interstate transmission of electric power through FERC and through other federal agencies, and certain environmental, health and safety matters. State and local governments regulate the siting, permitting, construction and operation of power generation facilities, the retail sale of electricity and certain other environmental, health, safety and permitting matters.

United States Federal Regulation of the Power Generation Facilities and Electric Transmission

The United States federal government regulates the wholesale sale of electric power and the transmission of electricity in interstate commerce through FERC, which draws its jurisdiction from the FPA, as amended, and from other federal legislation such as the PURPA, the Energy Policy Act of 1992, and the EPACT 2005. EPACT 2005 repealed the Public Utility Holding Company Act of 1935 and replaced it with the Public Utility Holding Company Act of 2005, or PUHCA.

Federal Regulation of Electricity Generators

The FPA provides FERC with exclusive ratemaking jurisdiction over all public utilities that engage in wholesale sales of electricity and/or the transmission of electricity in interstate commerce. The owners of renewable energy facilities selling at wholesale are therefore generally subject to FERC’s ratemaking jurisdiction. FERC may authorize a public utility to make wholesale sales of electric energy and related products at negotiated or market-based rates if the public utility can demonstrate that it does not have, or that it has adequately mitigated, horizontal and vertical market power and that it cannot otherwise erect barriers to market entry. Entities granted market-based rate approval face ongoing filing and compliance requirements. Failure to comply with such requirements may result in a revocation of market-based rate authority, disgorgement of profits, civil penalties or other remedies that FERC finds appropriate based on the specific underlying facts and circumstances. In granting market-based rate approval to a wholesale generator, FERC also typically grants blanket authorizations under Section 204 of the FPA and FERC’s regulations for the issuance of securities and the assumption of debt liabilities.

Table of Contents

If the criteria for market-based rate authority are not met, FERC has the authority to impose conditions on the exercise of market rate authority that are designed to mitigate market power or to withhold or rescind market-based rate authority altogether and require sales to be made based on cost-of-service rates, which could in either case result in a reduction in rates. FERC also has the authority to assess substantial civil penalties (potentially over $1.0 million per day per violation) and impose other monetary or regulatory penalties for failure to comply with tariff provisions or the requirements of the FPA.

FERC approval under the FPA may be required prior to a change in ownership or control of voting interests, directly or through one or more subsidiaries, in any public utility (including one of our U.S. project companies) or any public utility assets. FERC approval may also be required for individuals to serve as common officers or directors of public utilities or of a public utility and certain other companies that provide financing or equipment to public utilities.

FERC also implements the requirements of PUHCA applicable to “holding companies” having direct or indirect voting interests of 10% or more in companies that (among other activities) own or operate facilities used for the generation of electricity for sale, which includes renewable energy facilities. PUHCA imposes certain record-keeping, reporting and accounting obligations on such holding companies and certain of their affiliates. However, holding companies that own only exempt wholesale generators (“EWGs”) foreign utility companies, and certain qualifying facilities under PURPA are exempt from the federal access to books and records provisions of PUHCA. EWGs are owners or operators of electric generation facilities (including producers of renewable energy, such as solar projects) that are engaged exclusively in the business of owning and/or operating generating facilities and selling electricity at wholesale. An EWG cannot make retail sales of electricity, may only own or operate the limited interconnection facilities necessary to connect its generating facility to the grid, and faces restrictions in transacting business with affiliated regulated utilities.

Regulation of Electricity Sales

Electricity transactions in the United States may be bilateral in nature, whereby two parties contract for the sale and purchase of electricity, subject to various governmental approval processes or guidelines that may apply to the contract, or they may take place within a single, centralized clearing market for purchases and sales of energy, electric generating capacity and ancillary services. Given the limited interconnections between power transmission systems in the United States and differences among market rules, regional markets have formed as part of the power transmission systems operated by regional transmission organizations (“RTOs”) or independent system operators (“ISOs”) in places such as California, the Midwest, New York, Texas, the Mid-Atlantic region and New England.

Federal Reliability Standards

EPACT 2005 amended the FPA to grant FERC jurisdiction over all users, owners and operators of the bulk power system for the purpose of enforcing compliance with certain standards for the reliable operation of the bulk power system. Pursuant to its authority under the FPA, FERC certified the North American Electric Reliability Corporation (“NERC”) as the entity responsible for developing reliability standards, submitting them to FERC for approval, and overseeing and enforcing compliance with them, subject in each case to FERC review. NERC, in turn, has delegated certain monitoring and enforcement powers to regional reliability organizations. Users, owners, and operators of the bulk power system meeting certain materiality thresholds are required to register with the NERC compliance registry and comply with FERC-approved reliability standards.

Table of Contents

In the western United States, NERC has a delegation agreement with the Western Electricity Coordinating Council (“WECC”) whose service territory extends from Canada to Mexico and includes the provinces of Alberta and British Columbia, the northern portion of Baja California, Mexico, and all or portions of the 14 western states in between. WECC is the regional entity responsible for coordinating, promoting and enforcing bulk power system reliability in its service territory. Any entity that owns, operates or uses any portion of the bulk power system must comply with NERC or WECC’s mandatory reliability standards. Failure to comply with these mandatory reliability standards may subject a user, owner or operator to sanctions, including substantial monetary penalties, which range from $1,000 to $1 million per day per violation for the most severe cases, where companies show negligence and lack evidence of adequate compliance.

Federal Environmental Regulation, Permitting and Compliance

Construction and operation of power generation facilities, including solar power plants, and the generation and electric transmission of renewable energy from such facilities are subject to environmental regulation at the federal, state and local level. State and local regulatory processes are discussed separately in a subsequent section. At the federal level, environmental laws and regulations typically require a lengthy and complex process for obtaining licenses, permits and approvals prior to construction, operation or modification of a generation project or electric transmission facilities. Prior to development, permitting authorities may require that project developers consider and address, among other things, the impact on water resources and water quality, endangered species and other biological resources, compatibility with existing land uses and zoning, agricultural resources, archaeological, paleontological, recreational and cultural considerations, environmental justice and cumulative and visual impacts. In an effort to identify and minimize the potential impacts to these resources, power generation facilities may be required to comply with a myriad of federal regulatory programs and applicable federal permits under the NEPA, the Endangered Species Act, the Clean Water Act, the National Historic Preservation Act, the Resource Conservation and Recovery Act, the Comprehensive Environmental Response, Compensation, and Liability Act, the Environmental Protection and Community Right-to-Know Act and the National Wilderness Preservation Act, among other federal laws.

In addition, various federal environmental, health and safety regulations applicable during the construction phase are also applicable to the operational phase of power generation facilities. During the operational phase, obtaining certain federal permits or federal approval of certain operating documents (e.g., O&M plans, the spill prevention, control and countermeasure plan, and an emergency and preparedness response plan), as well as maintaining strict compliance with such permits or operating documents, is mandatory. Failure to maintain compliance may result in the revocation of any applicable permit or authorization, civil and criminal charges and fines or potentially the closure of the plant.

U.S. Federal Income Tax Reform

On December 22, 2017, the TCJA was signed into law. The centerpiece of the TCJA is the permanent reduction in the corporate income tax rate to 21% from 35% under prior law. Among other changes, the TCJA imposes new limitations on interest deductions, imposes a new excise tax on certain payments made to non-U.S. related parties, changes the rules relating to the use of NOLs and temporarily changes the rules relating to depreciation deductions.

The TCJA limits net business interest expense deductions to 30% of adjusted taxable income. For 2018 through 2021, this amount generally approximates to earnings before interest, taxes, depreciation and amortization (i.e., EBITDA). For tax years beginning after December 31, 2021, adjusted taxable income is determined by adding back only interest and taxes (i.e., it generally will approximate EBIT). The amount of interest paid or accrued that exceeds 30% of adjusted taxable income is treated as excess interest expense and may be carried forward to future taxable years. TCJA does not provide any grandfathering for debt that existed prior to enactment. This new limitation replaces the earnings stripping rules under Section 163(j) of the IRC that applied to interest paid on certain debt to or guaranteed by a related party.

The TCJA also imposes an excise tax on certain deductible payments, including interest, made by certain U.S. corporations to a non-U.S. related party to the extent the payment is not subject to U.S. withholding tax (the “BEAT”). The BEAT payable for any taxable year is an amount equal to the excess, if any, of (i) 10% (5% in 2018 and 12.5% after 2025) of the taxable income of the taxpayer calculated without regard to any deductions allowed for base erosion payments for the taxable year and certain net operating losses attributable to base erosion payments, over (ii) the taxpayer’s regular tax liability reduced by certain tax credits. The BEAT only applies to corporations with average annual gross receipts of at least $500M for the prior three-year period and that have made outbound deductible payments that constitute at least 3% (2% for financial group members) of the aggregate amount of certain deductions allowed for the taxable year (both generally determined on a group-wide basis).

Table of Contents

NOLs generated on or before December 31, 2017 can generally be carried back two years and carried forward up to twenty years and can be applied to offset 100% of taxable income in such years. Under the TCJA, however, federal NOLs incurred in 2018 and in future years may be carried forward indefinitely but generally may not be carried back. Additionally, the deductibility of such federal NOLs is generally limited to 80% of taxable income in such years. The rules regarding “ownership changes” under Section 382 of the IRC were left unchanged.

Under prior law, the cost of property was required to be capitalized and recovered over time through annual deductions for depreciation or amortization. Tangible property generally was depreciated under MACRS. Most of the equipment used in solar power projects, such as Solana and Mojave, qualifies for five-year depreciation under MACRS. Additionally, some equipment used in solar power projects qualified for bonus depreciation if it was equipment placed in service prior to 2020 (with a phase down for property placed in service after 2017). The TCJA temporarily extends and modifies the additional first year depreciation deduction. Under the TCJA, generally, bonus depreciation is 100% for property acquired and placed in service after September 27, 2017 and before 2023.

U.S. Federal Considerations for Renewable Energy Generation Facilities

The United States provides various federal, state and local tax incentives to stimulate investment in renewable energy generation capacity, including solar power. These tax incentives are subject to change and, possibly, elimination in the future. Certain U.S. federal income tax incentives are described below.

Section 1603 U.S. Treasury Grant Program

In lieu of claiming certain U.S. federal income tax credits, in particular, the ITC, owners of eligible solar energy property were eligible for a period of time to receive a cash grant from U.S. Treasury equal to 30% of the tax basis of the eligible property. Among other requirements, to be eligible for a 1603 Cash Grant, the eligible property must have been placed in service in 2009, 2010 or 2011 or, for property not placed in service during that period, the construction of the specified energy property must have begun after December 31, 2008 and before January 1, 2012. In addition, eligible solar energy property must be placed in service by January 1, 2017. Applicants who began construction after December 31, 2008 and before January 1, 2012, but who did not place the eligible solar energy property in service prior to October 1, 2012, were required to file a preliminary 1603 Cash Grant application prior to October 1, 2012. These applicants were further required to file a final or “converted” 1603 Cash Grant application no later than 180 days after the eligible solar energy property was placed in service. The preliminary 1603 Cash Grant application for Solana was filed in September 2012, and the final 1603 Cash Grant application for Solana was filed on November 14, 2013 with additional information provided to the U.S. Treasury in 2014. A final award from the U.S. Treasury was made as of October 2014. The preliminary 1603 Cash Grant application for Mojave was filed on September 14, 2012. Mojave reached COD in December 2014, and a final 1603 Cash Grant application was filed on February 5, 2015. A final award from the U.S. Treasury was made to Mojave as of September 2015.

Under the 1603 Cash Grant, certain persons, “disqualified persons,” are ineligible to receive the 1603 Cash Grant and are prohibited from owning a direct or indirect interest in otherwise 1603 Cash Grant-eligible solar energy property, unless the indirect interest is held through an entity taxable as a C-corporation for U.S. federal income tax purposes. 1603 Cash Grants are subject to recapture during the five-year period beginning on the date the eligible solar energy property is placed in service. The amount of the 1603 Cash Grant subject to recapture decreases ratably over the five-year recapture period. Among other events, failure of the eligible property to be used for its intended purpose or the direct or indirect transfer to a disqualified person (as described above) will cause recapture of the 1603 Cash Grant. Portions of the Solana and Mojave Cash Grant awards remain subject to this potential recapture.

Federal Loan Guarantee Program

The DOE, in an effort to promote the rapid deployment of renewable energy and electric power transmission projects, was authorized to grant guarantees with respect to certain loans to renewable energy projects and related manufacturing facilities and electric power transmission projects under Section 1703 of EPACT 2005. Previously, the DOE also granted guarantees with respect to certain loans made under Section 1705 of EPACT 2005. In order to have qualified for the Section 1705 program, physical construction must have commenced at the primary site of the project on or before September 30, 2011. NEPA review must have been completed prior to the issuance of a loan guarantee. In May 2011, the Section 1705 program expired by statute, and the DOE announced that it would no longer accept new applications under that program. On September 30, 2011, the Section 1705 loan guarantee program closed with no further loan guarantees to be issued. The DOE has also closed the Section 1703 loan guarantee program for solar assets, although it is still open for other technologies.

Table of Contents

The senior debt for Solana and Mojave is guaranteed by the DOE pursuant to the Section 1705 loan guarantee program.

State and Local Regulation of the Electricity Industry in the United States

State regulatory agencies in the United States have jurisdiction over the rates and terms of electricity service to retail customers. Regulated investor-owned utilities often must obtain state approval for the contracts through which they purchase electricity, including renewable energy, if they seek to pass along the costs of these contracts to their retail ratepayers. Municipal utilities and electric cooperatives are typically governed on these matters by their city councils or elected boards of directors. Different states apply different standards for determining acceptable prices for utility procurement contracts, including PPAs. Our electricity generation project companies operate in Arizona and California. Information about the regulatory frameworks in Arizona and California is provided below.

United States State-Level Incentives

In addition to federal legislation, many states have enacted legislation, principally in the form of renewable portfolio standards, or RPS, which generally require electric utilities to generate or purchase a certain percentage of their electricity supplied to consumers from renewable resources. In certain states, it is not only mandatory to meet these percentages from renewable resources, which in general are on the increase, but also electric utilities may be required to generate or purchase a percentage of their electricity supplied to consumers from specific renewable energy technologies, including solar technology. Depending upon the state, various certifications, permits, contracts and approvals may be required in order for a project to qualify for particular RPS programs. Some states, for example, require that only renewable energy generated in-state counts towards the RPS. According to the Database of State Incentives for Renewable Energy, as of November 2018, 32 states and United States territories have adopted some type of RPS standards. Although there is currently no federal RPS program, there have been proposals to create a federal RPS standard for renewable energy.

RECs are typically used in conjunction with RPS programs as tradable certificates demonstrating that a certain number of kWh have been generated from renewable resources. Under many RPS programs, a utility may generally demonstrate, through its ownership of RECs, that it has supported an amount of renewable energy generation equal to its state-mandated RPS percentage. The sale of RECs can represent a significant additional revenue stream for renewable energy generators. In RPS states where a liquid REC market does not exist, renewable energy can be bought or sold through “bundled” PPAs, where the PPA price includes the price for renewable energy attributes. Some states require that RECs and the associated electricity be purchased together in order to count towards the RPS. In states that do not have RPS requirements, certain entities buy RECs voluntarily. These RECs generally have lower prices than RECs that are used to meet RPS obligations. The price of RECs can vary significantly, depending on their availability, which in turn depends upon the amount of renewable generation that has been put in service in a state that has implemented RPS requirements. In some states, the number of successful projects has generated more RECs than required to meet the applicable RPS requirements for a given year or years, leading to steep drops in the market price for RECs. Additionally, demand for RECs can be driven by requirements (such as those imposed under the California Environmental Quality Act) that development projects mitigate potential significant greenhouse gas (“GHG”) impacts identified in connection with environmental clearances.

Effective 2018, California enacted legislation that increases its existing RPS to 60.0% by 2030 and 100% by 2045 for publicly-owned and investor-owned utilities, or IOUs. Arizona set an RPS of 15% by 2025, with 30% of the RPS to be met from distributed generation.

Other incentives that states and localities have adopted to encourage the development of renewable resources include property and state tax exemptions and abatements, state grants, and rebate programs. In addition, a number of states collect electricity surcharges on residential and commercial users and through public benefit funds reinvest some of these funds in renewable energy projects. California offered a property tax incentive for certain solar energy systems installed between January 1, 1999 and December 31, 2016. The Arizona Department of Revenue provides a corporate tax credit based on production for solar, wind, or biomass systems that are 5 MW or larger and are installed on or after December 31, 2010 and before January 1, 2021.

Solar generation may also be incentivized by state GHG emission reduction measures, such as California’s cap and trade scheme, which caps and reduces GHG emissions. The California cap and trade program went into effect with respect to the electricity and other sectors starting in 2013.

Arizona

Regulation of Retail Electricity Service in Arizona

The Arizona Corporation Commission (“ACC”) has complete and exclusive jurisdiction over the rates and terms under which regulated utilities may provide electricity service to retail customers in Arizona. Under the Arizona Constitution, the ACC has unilateral authority over all utility regulation, including electric and natural gas utilities. The ACC also oversees all rate cases for its jurisdictional utilities, and as such has oversight of renewable energy procurement contracts by regulated electric utilities. Under Arizona’s Renewable Energy Standard & Tariff (“REST”) regulated electric utilities must supply an increasing percentage of their retail electric energy sales from eligible renewable resources, including solar, wind, biomass, biogas and geothermal technologies. The renewable energy requirement is 8% of retail electric sales in 2018 and increases annually until it reaches 15% in 2025.

Unlike many other state regulatory commissions, the ACC does not approve PPAs executed by regulated utilities, nor does it issue rulings of “prudency” regarding PPAs. This practice leaves a utility somewhat at risk of recovering its costs until a successful rate case finding is rendered by the ACC. Rate recovery requests may not be filed until the utility begins to make actual expenditures for power procurement. In the case of Solana, however, the power purchaser, Arizona Public Service Company, or APS, voluntarily sought a hearing before the ACC to request its informal opinion of the prudency of the Solana PPA. After ACC staff conducted an analysis of the costs and benefits of Solana to Arizona ratepayers, it recommended to the ACC commissioners that the PPA should be deemed “a reasonable means” by which APS could meet its requirements under the REST. The ACC affirmed the staff’s recommendation on September 30, 2008, thereby providing greater assurance of APS’s successful rate recovery request.

Performance and Operational Provisions of Solana’s PPA

The PPA executed between APS and Solana’s project company, Arizona Solar, contains provisions related to guarantees of performance (e.g., provision of minimum annual REC eligible energy quantities to APS). The provisions are largely intended to protect APS’ ability to meet its mandatory requirements under the REST, and to prevent APS from having to procure REC eligible power elsewhere at an unknown, and possibly higher, cost than the PPA price.

Siting and Construction of New Power Generation Facilities in Arizona

The Arizona Power Plant & Transmission Line Siting Committee, or Siting Committee, oversees utility and private developer applications to build power plants (of 100 MW or more) or transmission projects (of 115,000 volts or more) within Arizona. The Siting Committee holds public meetings and evidentiary hearings to determine whether a proposed generation or transmission project is compatible with the preservation of the state’s environmental protection interests, and if the finding is affirmative, makes a recommendation to the ACC to grant a Certificate of Environmental Compatibility, to the applicant. The ACC then has authority to approve, decline or modify the Siting Committee’s recommendation.

The ACC granted Certificates of Environmental Compatibility to Solana on December 11, 2008, for both the 280 MW solar generation project and its associated 20.8-mile, 230 kilovolt transmission line. Both the generation facility and transmission line Certificates of Environmental Compatibility contain obligatory conditions and stipulations, none of which could present a risk to Solana during the operational phase.

Other Arizona Permitting and Compliance Frameworks

Various state and county regulations, mostly related to the environment and public health and safety, are applicable during the operational phase of a solar power plant located in Maricopa County, Arizona. Such regulations include the Arizona Aquifer Water Quality Standards and Aquifer Protection Permit Rules, the Maricopa County Special Use Permit Stipulations, the Maricopa County Air Pollution Control Regulations, and the Maricopa County Zoning Ordinances and Regulations. Obtaining a permit or requesting the approval of certain operating plans, as well as strict compliance with such permits and plans, is mandatory. Failure to comply may result in the revocation of the permit or authorization, civil and criminal charges and fines, or potentially the closure of Solana.

In addition, in accordance with the NEPA designation of a Finding of No Significant Impact (FONSI) issued by the DOE, Solana must comply with certain water requirements due to the reduction in tail water runoff being contributed to a wash located near the site. In coordination with Arizona Game & Fish Department and the U.S. Fish and Wildlife Service, Solana must provide 447 acre-feet of water annually as a direct off-set to the reduction in tail water runoff from the site. This requirement is for the duration of Solana, and failure to comply would trigger an administrative procedure that could cause temporary closure of the plant until the non-compliance condition is cured.

Regulations Affecting Operating Generating Facilities in Arizona

Many of the permits obtained for Solana carry specific conditions that must be complied with during the operational phase of the facility and which are continuously monitored, measured, and documented by the Solana plant operators. The primary obligations that commenced during commissioning and/or commercial operation are those related to reliability, emergency response, potential hazards of waste disposal, and human health and safety. These requirements originate with federal laws, and in many cases are enforced via delegated authority from the appropriate federal agency to a state or county agency. These include:

•	NERC Reliability Standards and Critical Infrastructure Plans, delegated to WECC as the regional authority;

•	Emergency Planning and Community Right-to-Know Act, delegated to the Arizona Division of Emergency Management;

•	Resource Conservation and Recovery Act, delegated to EPA Region 9 in San Francisco, California; and

•	Occupational Safety and Health Administration federal requirements.

California

Regulation of Retail Electricity Service in California

The California Public Utilities Commission, or CPUC, governs, among other entities, California’s three large investor-owned utilities, including Pacific Gas & Electric Company, or PG&E. PG&E is required to file an RPS procurement plan annually with the CPUC. Once the CPUC approves the plan, PG&E issues a request for offers, or RFO, for renewable energy. It then evaluates all of the bids using a “least-cost, best-fit” evaluation process approved by the CPUC and develops a short list of acceptable bids. In August 2008, Mojave was submitted as a renewable solar thermal project in response to PG&E’s 2008 RFO solicitation and placed on its short list for additional negotiations. After two years of negotiations, PG&E and Mojave Solar executed a final PPA, for which PG&E filed with the CPUC an advice letter requesting approval of the PPA in July 2011. The CPUC reviewed the PPA and approved the contract by issuing a formal decision in November 2011. The terms of the PPA govern Mojave during its development, construction and operating period. The CPUC historically does not retroactively apply new regulations or rulings to previously approved PPAs that would result in any economic impact.

Performance and Operational Provisions of Mojave’s PPA

The PPA executed between PG&E and Mojave’s project company, Mojave Solar, contains provisions related to guarantees of performance (e.g., provision of minimum annual REC eligible energy quantities to PG&E). The provisions are largely intended to protect PG&E’s ability to meet its mandatory requirements established by the CPUC, and to prevent PG&E from having to procure REC eligible power elsewhere at an unknown, and possibly higher, cost than the PPA price.

Siting and Construction of New Power Generation Facilities in California

The California Energy Commission, or CEC, is the lead agency for licensing thermal power plants 50 MW and larger under the California Environmental Quality Act and has a certified regulatory program under such Act. The CEC is comprised of five commissioners, two of whom oversee all hearings, workshops and related proceedings on a specific project. The CEC’s siting process evaluates Applications for Certification, or AFCs, to ensure that only power plants that are actually needed will be built, provides review by independent staff with technical expertise in public health and safety, environmental sciences, engineering and reliability, ensures simultaneous review and full participation by all state and local agencies, as well as coordination with federal agencies, resulting in issuance of one regulatory permit within a specific time frame, with full opportunity for participation by public and interest groups.

On August 10, 2009, Mojave’s AFC for its nominal 250 MW project was filed with the CEC. The CEC approved Mojave’s AFC with the CEC decision issued on September 8, 2010. The CEC monitors the power plant’s construction, operational phase and eventual decommissioning through a compliance proceeding.

Regulations Affecting Operating Generating Facilities in California

Mojave must maintain compliance with the CEC decision conditions of certification. These conditions of certification address, among others, biological resources, health and safety, cultural resources, fire safety, and water. The conditions require Mojave to provide plans, notifications, and other reports on an ongoing basis. As noted above, such compliance is monitored by CEC staff. Per the CEC decision, “failure to comply with any of the Conditions of Certification or the compliance conditions may result in reopening of the case and revocation of Energy Commission certification; an administrative fine; or other action as appropriate.” Additional regulations are administered by the California Independent System Operator and under the terms of the federally administered Large Generator Interconnection Agreement.

Regulation in Mexico

Overview

The following is a description of the regulation of the Mexican power industry applicable to the conventional or natural gas generation of electricity.

Pursuant to the Mexican Constitution, the electricity industry in Mexico was entirely controlled by the federal government, acting through the Federal Electricity Commission, or CFE, an entity wholly owned and controlled by the Mexican government, and legally independent from the Mexican Ministry of Energy, Secretaría de Energía. CFE was the only entity authorized to provide electricity directly to the public and to supply services to the Mexican wholesale market. CFE was also responsible for the construction and maintenance of infrastructure necessary for the delivery of electricity, such as the national electric grid, the Sistema Eléctrico Nacional, or SEN.

As a result of Mexico’s energy reform bill enacted on December 21, 2013, articles 25, 27 and 28 of the Mexican Constitution were amended in order to end the long-standing state monopoly in the oil, petrochemical and power sectors, and allow private investment in these areas for their development in an open market. Hence, the power generation sector is now open to full private participation and investment, creating a competitive spot market in power generation, although electric transmission and distribution will remain public services to be provided exclusively by CFE. With the enactment of the secondary legislation, the generation, transmission, distribution and commercialization of power in Mexico is governed by a new legal framework which will likely improve the development of the sector.

Notwithstanding the legal changes, we do not expect any negative consequences for ACT Energy Mexico, or ACT, or for the power generated and delivered to Pemex Gas y Petroquímica Básica.

Until the recent energy reform, the whole set of activities regarding generation, transmission, distribution and commercialization of power for public use were considered areas of national strategic importance. As a result, such activities were carried out exclusively by CFE. The national electric grid was also controlled by CFE through the Centro Nacional de Control de Energía, or the CENACE, which operated the national electric grid and controlled delivery of all electricity generated by CFE and private generators connected to the grid. CFE was a vertically-integrated state monopoly that served the whole country, and CENACE was a semi-independent agency that was part of CFE. As a result of the energy reform, CENACE became a decentralized public agency, which will continue to be responsible for the operation and control of the national electric grid with the aim of having an impartial third party (not CFE) operate the wholesale electricity market, guaranteeing open access to the national electric grid for both transmission and distribution of electricity. CENACE has emerged as an Independent System Operator, or ISO, which is a figure adopted worldwide in other mature energy markets.

Table of Contents

The generation, transmission and distribution of electricity were regulated by the Ley del Servicio Público de Energía Eléctrica, or Electricity Law; enacted in 1975 and amended in 1992. Since the implementation of the 1992 amendment to the Electricity Law, private entities have been allowed to participate in the following activities not considered public utility services, as defined by such law:

Cogeneration . The electricity produced is used to supply power to the establishments associated with the cogeneration process and/or the shareholders of the cogeneration company;

Self-Supply Generation . The electricity produced is used for the self-supply purposes of the holder of the relevant self-supply power generation permit and/or its shareholders;

Independent Power Production . All the electricity produced is delivered to CFE;

Small-Scale Production . The electricity produced does not exceed 30 MW and is used for export purposes or the supply of all power output is sold to CFE;

Exports. The electricity produced is exported in its entirety; and

Imports for Independent Consumption. The import of power is used for self-supply purposes.

The regulatory framework of the Mexican power industry is undergoing a transitory period, as the energy reform is still in the process of being fully implemented, given that the secondary legislation derived from such amendments to the Mexican Constitution was published in the Official Federal Gazette, or Diario Oficial de la Federacion, on August 11, 2014, and there are still a few regulatory instruments pending issuance. See “—Regulation in Mexico—Transitory Regime—Electric Industry Law.”

The changes made by the energy reform are being implemented through a profound modification of the legal framework that had governed the development of the energy industry in the country, which has involved the entrance into force of new laws and the amendment of current laws.

Conventional Electricity Generation in Mexico

The former legal framework for conventional electricity generation in Mexico included the regulation of fossil fuels, such as carbon, diesel, fuel oil and natural gas, as well as nuclear fission regulation, which includes nuclear power plants and all related activities.

Accordingly, power generation under independent power production or self-supply schemes was not considered a public utility service and, therefore, could be performed by private companies and individuals pursuant to permits issued by the Energy Regulatory Commission, Comisión Reguladora de Energía , or CRE. The CRE is a federal agency created in 1995 in order to enforce the laws and regulations relating to natural gas and electricity, and has the authority to issue permits, set tariffs, supervise, ensure adequate supply and, in the case of gas, promote competition.

As previously indicated, the Mexican federal government, acting through CFE, controlled the entire chain of activities related to electric power, including generation, sale, distribution and transmission. The energy reform allows the private sector to openly participate in two important parts of the production chain: the generation and the sale of electricity.

Pursuant to the reform, the private energy sector is now able to invest in electricity generation with the requisite permits. The sale of electricity by private parties is already taking place, with the initiation of operations of the Wholesale Electricity Market, Mercado Electrico Mayorista , or MEM, in Mexico under the new legal framework, privately sold electricity is being transmitted and distributed by CFE.

The reforms are expected to have positive effects on the electricity industry in Mexico, allowing the private sector to play an active role where a government monopoly once existed, generating greater investment and better technology.

As a result of the energy reform, the electricity sector has ceased to be a chain of activities vertically integrated in a partially privatized sector, and has become an area open to private investment in which, although CFE will maintain control, the possibility of private sector investment has increased significantly and will continue to be increased through a more flexible regulatory scheme that permits the execution of contracts to carry out various activities and the creation of new markets in the electricity sector. Among the most significant changes are the following:

Participation that is open to the private sector in the generation of electricity through a permit granted by CRE. Private parties may also sell the energy generated and transmitted by CFE through commercial schemes.

Participation of the private sector, together with CFE, in the activities of transmission and distribution through the execution of the corresponding service contracts.

Participation of the private sector in activities of financing, maintenance, management, operation and expansion of the power infrastructure through service contracts with CFE, with adequate compensation.

Transformation of the CENACE into a decentralized public body responsible for the operational control of the national electric grid, so that it is an impartial third party (and not the CFE) that operates the wholesale electricity market, guaranteeing open access to the national electric grid, for both transmission and distribution of electric power.

Creation of the MEM, operated by the CENACE, in which the participants carry out electric power purchase and sale transactions through contracts between the participants in the MEM. The CENACE is now responsible for managing the supply and demand of the MEM participants, carrying out transactions and generating prices continuously. The price paid in the MEM transactions represents a competitive price, reflecting the costs of generation and other operating costs of electricity, as well as the volume of electric power demanded and supplied in the MEM.

102

Table of Contents

Creation of the trader, under the new Electric Industry Law, as the holder of a MEM participant agreement, which purpose is to carry out trading activities (execution of contracts for purchase and sale of electricity within the MEM, among others). The traders may sign contracts with qualified users (through the provider-trader) or execute such contracts with other traders (non-provider trader).

The permits granted by the CRE under the currently repealed Electricity Law, will continue in force under its terms. The holders of those permits that choose to remain under the provisions of the Electricity Law may, at any time, transfer to the new rules.

The Geothermal Energy Law, the purpose of which is to regulate the recognition, exploration and exploitation of geothermal resources for the use of underground thermal energy within the limits of Mexican territory, in order to generate electricity or use it otherwise.

The activities regulated by the Geothermal Energy Law are considered to be in the public interest and their development will have preference over activities of other sectors when there is a conflict.

The activities pursued under the Geothermal Energy Law will be carried out through different registries, permits, authorizations and concessions granted by the competent authorities applicable for each case. For exploration activities, a permit will be sufficient, while for exploitation activities, a concession will be required.

Amendment of several articles of the National Water Law, for the purpose of (i) adapting certain definitions of that law to the new definitions introduced by the Geothermal Energy Law; (ii) including geothermal fields under regulated, prohibited or reserved zones; and (iii) establishing the obligation of requesting the relevant permits, authorizations and concessions from the National Water Commission in order to engage in the activities of geothermal fields exploration.

Electric Industry Law

The Electric Industry Law, as part of the package of secondary legislation that implements the constitutional energy reform, regulates planning activities, the control of the national electric grid, the public services of transmission and distribution of electricity, and all other activities related to the Mexican energy industry, in order to promote the sustainable development of the industry and to ensure its continuous, efficient, and secure operation for the benefit of all users, as well as the fulfillment of the obligations to provide a general and public service of electricity, to develop clean energies, and to reduce contaminating emissions.

Pursuant to the Electric Industry Law, the government holds the operational control of the national electric grid, through the CENACE, and CENACE, as an ISO, will indicate the elements for the national transmission grid and the related operations which may correspond to the wholesale market.

Regulations of the Electric Industry Law

The Regulations of the Electric Industry Law provide details for the application of the Electric Industry Law and complete the implementation of the restructured electric industry in Mexico.

These regulations expand on certain administrative procedures in the electric industry, such as the development of public bidding procedures by CFE, for private sector contracts for activities related to the national electric grid; the specific requirements for the application for power generation and power supply permits with CRE; the process for infrastructure contributions by the private sector to the State; and the registration of participants in the wholesale spot market with CENACE.

Permits and Authorizations

Pursuant to the Electric Industry Law, all power plants with a capacity greater than or equal to 0.5 MW and all power plants of all capacities represented by a generator (i.e., the holder of one or more generation permits or holder of a wholesale market participant agreement that represents the corresponding power plants in the wholesale market or, prior authorization granted by CRE, power plants located abroad) require a generation permit granted by CRE. Authorization granted by CRE is also required for the import of electricity from a power plant located abroad and interconnected exclusively to the national electric grid. Power plants of any capacity exclusively intended for personal use during emergencies or interruptions in electric supply will not require a permit.

103

Table of Contents

The Electric Industry Law provides for several requirements which generators who represent power plants interconnected to the national electric grid have to comply with, including, among others, the execution of the corresponding interconnection agreements, issued by CRE. Regarding the production of their power plants, generators may carry out commercialization activities which include, among others, the following: (i) representing exempt generators (i.e., owner or holder of one or more power plants which do not require or have a generation permit) in the MEM; (ii) carrying out sale and purchase transactions of energy, related services included in the MEM, and power or other products which ensure enough resources to meet the electric demand, and all other products, duties or penalties required for the efficient operation of the national electric grid, among others; and (iii) executing, among others, the corresponding electric coverage agreements (i.e., agreement entered into by participants of the MEM which purpose is the sale and purchase of electric energy or related products) with other MEM participants, including other generators, traders (i.e., holder of a MEM participant agreement which purpose is to carry out commercialization activities), and qualified users (i.e., final user who is registered before CRE to acquire electricity supply as a MEM participant or through a qualified provider).

Pursuant to the former legal framework for the Mexican electric industry, permits for self-supply, cogeneration, independent production, small production, import, and export of electricity were granted by CRE for indefinite periods of time, except for independent power producer permits, which were granted for 30-year renewable terms. In addition to the legal and technical requirements established by law to obtain such permits, CFE’s approval was required as part of CRE’s permit approval process. Pursuant to the transitory regime, such permits will be in force for the duration of the corresponding interconnection agreements executed under their scope; nevertheless, such interconnection agreements must achieve commercial operation by December 31, 2019 at the latest, or otherwise be cancelled.

CRE may also issue a supply permit for private parties, which will allow companies to participate in the MEM by carrying out transactions with final users, which are called “qualified users.” In this sense, private parties may supply power directly to consumers through bilateral long-term agreements, which will be partially regulated by the CRE.

Consequently, the Mexican power industry had been divided into two main areas: (i) the public service of electricity under CFE’s control, and (ii) the activities where private parties may be involved (such as where CFE actively promoted private investment in the construction and operation of power plants for supplying CFE and private parties under self-supply and cogeneration schemes).

While power generated in Mexico is still predominantly generated by CFE, there is a large amount of electricity generated by private energy producers, which generally fall under the categories of independent power production and self-supply generation, although cogeneration has come to be a relevant source of power as a result of certain amendments enacted in 2006 which allowed Pemex to develop new cogeneration projects independently and in collaboration with CFE. These amendments allowed Pemex to enter into the Pemex conversion services agreement and to receive the power generated by ACT.

As a consequence of the corresponding reforms the issuance of a new class of permit available to those interested in generating electricity is provided for pursuant to the Electric Industry Law. This permit expanded the ways in which entities are allowed to participate as energy producers under the Electric Industry Law and is within the scope of the CRE’s regulatory control.

The permits provided for in the Electric Industry Law are, as aforementioned, granted and issued by CRE, upon prior submission of the corresponding application, payment of the corresponding duties, all relevant legal and technical information, and project description. Such permits will be terminated or revoked pursuant to the different scenarios indicated in the Electric Industry Law and its regulations, and as determined by CRE.

The regulations list the documentation to be submitted to apply for a permit with CRE, as well as the corresponding timeline for the application procedure and the essential elements that CRE must include in the permit title.

Transmission and Distribution of Electricity in Mexico

Pursuant to the Electric Industry Law, regarding conventional energy generation, dispatchers and distributors are responsible for the national transmission grid and the general distribution grids and will operate their grids pursuant to the instruction provided by CENACE. Whereas in the past there were no regulatory limitations that would interfere with a private generator engaging in transmission activities, and, regarding distribution activities, these could only be performed by CFE, with the new regulatory framework derived from the constitutional reform and the legal provisions therein, the public service of electricity and its transmission are considered as strategic areas and will continue to be government-controlled, notwithstanding the possibility of the Mexican government, acting through CFE, to be able to enter into agreements with the private sector, or, acting through the Mexican Ministry of Energy, to form partnerships or enter into agreements with the private sector to carry out the financing, installation, maintenance, administration, operation or expansion of the infrastructure required to provide electricity transmission and distribution services, in terms of the provisions of the Electric Industry Law.

Such agreements will be awarded to private companies through bidding rounds, conducted by CENACE, which will determine the needs of the national electric grid, and carry out the corresponding tender processes. In addition, all dispatchers and distributors will have the obligation to execute the corresponding connection and interconnection agreements, based on the model contracts issued by CRE, regarding the interconnection of power plants or the connection of load centers, and the MEM regulations will indicate the criteria for CENACE to define the specifications for the required infrastructure necessary for the interconnection of power plants and the connection of load centers, as well as the mechanisms to determine preference matters for applications or requests and the procedure for their evaluation.

CFE is required by law to provide its wheeling (the transfer of electrical power through transmission and distribution lines to another utility), dispatch and backup services to all permit holders whenever the requested service is technically feasible on a first-come, first-served basis. CFE’s wheeling services are provided pursuant to an interconnection agreement and a transmission services agreement entered into between CFE and the relevant permit holder (in ACT’s case, these were executed by Pemex). Those agreements follow model contracts approved by the CRE, which also approves the methodology used to calculate the applicable tariffs. The permit holders must build their own transmission lines for self-use in order to connect to the power grid. In addition, permit holders are required to enter into a back-up services agreement with CFE, which also follow a model agreement approved by the CRE.

The Electric Industry Law incorporates new requirements to carry out the sale and purchase of electricity. Aside from being classified as a generator or qualified user, along with the need to comply with the rules issued by CRE for the execution of the corresponding agreements, there are new requirements for the interconnection to the transmission grid owned by CFE. The Electric Industry Law introduces and provides for the concepts of connection and interconnection, the first referring to the load points of users and the latter referring to generators’ power plants. Regarding interconnection, the most significant change is the need to execute new model agreements in order to adapt them to the new modalities and activities under the scope of regulation of the Electric Industry Law.

Furthermore, the transitory provisions contained in the Electric Industry Law provide that those interconnection agreements which were executed under the scope of regulation of the Electricity Law will remain in force, notwithstanding the possibility that executing the new contract models that have been issued by CRE may prove beneficial in order to adapt to the new changing aspects of the industry; as with previous agreements, companies will only be limited to the authorized activities under such contracts (e.g. wheeling will only be available for the amount of energy and for the specific purpose established therein). This suggests that new models of interconnection agreements may be more flexible to cover the implementation of the various activities allowed.

The regulations provide that CRE must implement a regulatory regime providing for the conditions for the procurement of the public services of transmission and distribution of electric power based on the principles of proportionality and equality, aiming to prevent transporters, distributors and suppliers from exercising excessive market power that could negatively affect final users. Such regulatory regime considers the degree of openness in the market, the concentration of participants and any other condition of the competition in every division of the industry. The regulations also establish the possible cases of curtailment of the services of transmission and distribution of electric power and provide for standard procedures in different situations.

Commercialization of Electricity

Under the Electric Industry Law, the trader is the holder of a MEM participant agreement, and carries out commercial activities, among which are executing electric coverage agreements for the sale and purchase of electricity within the MEM. Under the Electric Industry Law, electric coverage agreements are those agreements executed between MEM participants through which those participants engage in the sale of electric energy or related products. Traders may enter into such agreements with qualified users (through the figure of the provider-trader) or with other traders (who are not providers).

Excluding qualified users, basic providers provide the basic supply to all people who so request it and whose load centers are located in their operation areas. Qualified providers provide the qualified supply to qualified users in terms of free competition. Prior commencement of the qualified or basic supply services, the final user must execute a supply agreement with the appropriate provider, and such agreements will require registration before the Federal Attorney’s Office of Consumer, or Procuraduria Federal del Consumidor , or PROFECO. In this regard, CRE issues the general terms and conditions for the electrical supply services, which will determine the rights and obligations of the service provider and the final user, correspondingly.

Qualified users are those final users who are duly registered as such before CRE in order to acquire power as MEM participants or by a qualified provider. In terms of the Electric Industry Law, users holding load points with a demand greater than or equal to 3 MW may be included in the qualified users registry (but such amount will decrease in one MW per year following the first year until reaching 1 MW). In this case, having the property in which the electric power is intended to be supplied registered as qualified under the corresponding rules to be issued will suffice. Within the MEM, qualified users may purchase energy through electric coverage agreements executed with CENACE or directly with traders.

Supply

Supply activities carried out in the new electric industry may be either in the basic or qualified modalities. Power supply agreements may be executed by and between providers and final users, under the corresponding

supply permits issued by CRE. Basic supply refers to that which is provided by a provider under a regulated tariff to any applicant who is not a qualified user. “Qualified supply” refers to that which is provided in terms of free competition to qualified users.

For basic supply, private generators may participate in the auctions conducted by CENACE, in order for CFE to acquire the energy in the most convenient economic terms and conditions, and thus CFE will be able to supply power to users who so request it before CENACE, who will carry out the referred auction and determine whom the electricity will be purchased from. CRE will also determine the requirements that providers must comply with in order to acquire energy and execute contracts for electric coverage with users.

As for qualified supply, qualified providers may carry out transactions directly through long-term supply agreements with qualified users. Under these agreements, the parties are be free to agree upon the terms and conditions (including economic conditions) thereof, abiding by certain general guidelines issued by CRE.

Open Access

Both the Electric Industry Law and in the regulations thereunder establish that CFE is obligated to grant non-discriminatory open access to all users of the national electric grid. This enhances the existence of an open electricity market, where various competitors in almost all segments of the supply chain requiring the use of the national electric grid coexist and develop their activities. Open access is a crucial component of the electric industry since CFE, as owner of the grid, competes directly with other private sector participants in several activities of the industry, which could lead to a monopoly by CFE. In order to avoid such situation, the CENACE, as an independent system operator, will ensure competitive conditions for all users who want to use CFE’s infrastructure.

Pursuant to the regulations, CRE issued the general guidelines regarding open access conditions, the procedure for users to request such open access and the procedure to which the CENACE will be subject to grant this open access, among others.

Tariffs

Transmission, distribution, basic supply and last resort supply, as well as the operation of CENACE, are subject to regulatory accounting guidelines established by CRE. CRE has issued general administrative provisions regarding the methodology to determine the calculation and adjustment of the regulated tariffs for transmission, distribution, basic provider operation and CENACE operation services, as well as all related services which are not included in the MEM.

Dispatchers, distributors, basic providers and the CENACE are required to publish their tariffs, as indicated by CRE, through general administrative provisions.

Wholesale Spot Market, Mercado Eléctrico Mayorista

The Electric Industry Law provided for the creation of a MEM, operated by CENACE, in which participants can carry out a number of different transactions provided for in said law, among which are the sale of electricity and related products.

MEM participants can be (i) generators, (ii) provider-traders, (iii) non-provider traders, or (iv) qualified users, prior to execution of the corresponding agreement with CENACE. Transactions carried out within the MEM must be formalized through “electric coverage agreements” executed by and between such MEM participants. Generators, as MEM participants may, sell their generated energy and both traders and qualified users may purchase such energy through CENACE, which is the independent operator of the electric system.

CENACE is responsible for managing the supply and demand of MEM participants, conducting transactions and continuously generating prices. The price to be paid in MEM transactions has to be a “competition price” in terms of the Electric Industry Law and has to reflect elements such as electricity generation costs and other operating costs, as well as the amount of electricity demanded by and supplied within the MEM. Such competition price serves as a reference for long-term supply agreements between providers and qualified users, partially replacing the current CFE-published tariffs.

Even though the Electric Industry Law provides the general guidelines to which the operation of the MEM is subject, on September 8, 2015, the Mexican Ministry of Energy published the Guidelines of the Market ( Bases del Mercado Eléctrico ), as the general administrative provisions which establish the principles for the design and operation of the MEM. The regulations list certain topics which are described in depth in the Rules of the Market ( Reglas del Mercado) , such as the methodology that is used to forecast the level of demand in the spot market, information on market participants, and the methodology to determine the price of the electricity sold and purchased within the spot market.

The Guidelines are part of the Rules of the Market, which are administrative provisions of general application that specifically detail different aspects of the operation of the MEM, and determine the rules that all market participants, such as generators, traders, suppliers, non-supplier traders or qualified users, as well as the competent authorities must comply with. It further outlines the procedures they must follow in order to maintain the proper management, operation and planning of the MEM. Pursuant to the Guidelines, which were subsequently supplemented by guidelines for market practices, operational guidelines and criteria and operating procedures, the different participants of the electricity industry are able to carry out activities which are now open to private participation, due to the so-called energy reform that took place in late 2013 in Mexico, and which were implemented and now regulated through the Electric Industry Law and its Regulations (such activities include, among others, transactions of sale of electricity and related services, power, financial transmission rights and clean energy certificates).

Public Consultation

The Electric Industry Law and the regulations thereunder set out the obligation to carry out a prior consultation process in the event a project is to be developed in certain lands where communities or indigenous people are found. This obligation, which is established in international treaties, as well as in Article 2 of the Political Constitution of the United Mexican States, is now established in the new legal framework to provide certainty regarding community and social issues in all projects within the electric industry.

The aforementioned general obligation is provided for in the Electric Industry Law and the regulations thereunder detail the specific procedure to be followed, including the filing of a social and cultural impact assessments before the Mexican Ministry of Energy and the different stages that the prior consultation entail, among others.

Transitory Regime

Given that the Electric Industry Law set various deadlines for the full implementation of its provisions (such as the issuance of the “Market Rules”, the full entry into operation of the MEM; or the Terms and Conditions for the Supply of Electricity), a transitory regime was established. This regime intended to provide clarity and certainty to all participants of the industry who had ongoing projects, or planned to start projects at that time of transition.

Permits

Permits granted by CRE, in accordance with the Electricity Law, will continue to be governed under the terms set out therein and other applicable provisions. Holders of such permits who decide to remain under the regulation of Electricity Law may, at any time, migrate to the new regime if it suits their interests.

Interconnection agreements

In order to be able to execute an interconnection agreement in terms of the Electricity Law (in the event not previously executed), those interested in doing so should have complied with the following conditions: (i) having obtained or having applied for a permit in any of the modalities provided by the Electricity Law, prior to the entry into force of the Electric Industry Law (August 11, 2014); (ii) having notified CRE about its intention to continue with the development of the relevant project; and (iii) having provided proof evidencing that the appropriate financing for the project has already been obtained, that they have already contracted the supply of the main equipment required for the project, and that at least 30% of the total investment for the project has been paid, before December 31, 2016. Additionally, it is possible to execute an interconnection agreement in terms of the Electricity Law if a company participated in an open season process, through which CRE granted transmission capacity to several participating companies.

The Electric Industry Law also provides certainty regarding interconnection agreements which have been executed with CFE prior to the enactment of the Electric Industry Law, as those agreements which were executed under the scope of regulation of the Electricity Law will remain in force for their entire duration (although they will not be subject to renewal or extension upon their termination). With the enactment of the Electric Industry Law, it is now only possible to modify executed interconnection agreements in relation to the load points, surplus sales, support services; cost of stamp wheeling and other conditions contained therein which may apply.

Permit holders who choose to remain under the scope of regulation of the Electricity Law and decide to keep their interconnection agreements will be governed by the terms and conditions set forth therein and, consequently, will not be subject to the rules of the MEM.

Notwithstanding the foregoing, it is important to mention that the transitory clauses of the Electric Industry Law provide that if those interconnection agreements executed under the provisions of the Electricity Law do not reach commercial operation by December 31, 2019 at the latest, then they will be cancelled.

Network’s Code

On April 8, 2016, the Network’s Code ( Código de Red ) was published in the Federal Official Gazzette. Such code establishes the conditions of efficiency, quality, reliability, continuity and sustainability in order to allow and promote the development, maintenance, operation, enlargement and modernization of the National Electric System in a coordinate way based on the technical-operative requirements, and in an economical and efficient way, under the principles of open access and without improper discrimination.

Among other provisions, the Network’s Code sets forth the obligation of different market participants to meet several technical requirements and improvements of their electric facilities with the purpose of ensuring the efficiency, quality, reliability, continuity and sustainability of the Sistema Eléctrico Nacional.

It is important to bear in mind that the Network’s Code will become effective by April 9, 2019, providing members of the industry (grandfathered or not) a three year period to complete all works necessary to meet the aforementioned requirements. Taking into consideration the foregoing, all members of the industry should finish such works by April, 2019. Strictly speaking, if any member of the industry does not timely comply with this obligation, the relevant penalties will be imposed.

Regulation in Peru

Below is a general overview of certain Peruvian electricity sector regulations. This overview should not be considered a full description of all regulations.

The Electric Transmission Sector

The Peruvian electric system serves energy to a large area of the country through its national grid, the SEIN (the Sistema Eléctrico Interconectado Nacional ) , that has transmission lines and substations operating at 500, 220, 138, 69 and 33-kV levels.

Pursuant to Law 28832, which is applicable to any transmission project commissioned after July 2006, the transmission facilities integrating the transmission grid are classified as those belonging to: either (i) the Guaranteed Transmission System, or Sistema Garantizado de Transmisión (SGT), for transmission facilities that are included in the transmission plan and developed pursuant to a concession agreement granted by the Peruvian government to the winner of a public tender, or (ii) the Complementary Transmission System, or Sistema Complementario de Transmisión (SCT), for transmission facilities that are either (a) included in the transmission plan and developed by the private entity that was awarded a concession as a result of the successful review of a private initiative proposal, or (b) not included in the transmission plan.

Under Law 28832, the projected expansions of the transmission system identified in the Peruvian transmission plan are part of the SGT. The government organizes tender procedures to call private investors interested in building the projected lines of the SGT. Under SGT Concession Agreements, the concessionaire shall build the lines and be responsible for their operation and maintenance. Recovery of the investment during the term of the contract (up to 30 years) is guaranteed thereunder. The concessionaire owns the transmission assets during the term of the contract. Upon expiry of the contract the assets return to the State which shall call a new tender if the lines are required at such time for the operation of the system.

Transmission lines of interest to generation plants, distribution networks or large consumers are part of the SCT. The lines of the SCT included in the Peruvian transmission plan and certain projects that exclusively serve the demand, as defined by the government, may be subject to tenders for the granting of SCT Concession Agreements up to 30 years. The rest of the SCT projects are subject to the general regime in which the owners of the SCT lines (for example, the generation companies building them to connect their plants to the system) are the holders of the respective Definitive Transmission Concession and own the transmission assets through the term of the concession.

Open Access Regime

The activity of electricity transmission is a public service according to Peruvian law; such service is subject to open access regulations, which imply that the owner of a transmission infrastructure is obliged to allow third parties to connect to the SEIN through its transmission facilities. However, third parties requesting access to a transmission system have the obligation to assume the costs of any additional investment required to increase the connection capacity, if required to make the interconnection feasible. The terms and conditions of the required new investments shall be negotiated in an interconnection agreement.

Access of third parties to the SGT with facilities that are not included in the Peruvian transmission plan requires a previous verification by the Comité de Operación Económica del Sistema Interconectado Nacional, or COES, of the technical conformity of such connection facilities. For those facilities needed for the electrical continuity of the SGT, the third party seeking access assumes the costs of expansion and compensation for their use, and the corresponding SGT concessionaire is responsible for the implementation, operation and maintenance of these facilities. The operation and maintenance costs of these facilities are those arising from the agreement between the SGT concessionaire and the third party seeking access.

111

Table of Contents

Pursuant Peruvian Law, the concessionaire owns the transmission infrastructure needed for the electrical continuity of the SGT. These infrastructures will be concession assets under the contract. As a general rule, under the SGT Concession Agreement, upon expiry of the contract the assets return to the Peruvian State.

If a private interconnection agreement is not reached through private negotiation, a request for an interconnection mandate can be filed before the Organismo Supervisor de la Inversión en Energía y Minería , or OSINERGMIN, who will determine the conditions applicable to the connection, if it is technically feasible. To that end an assessment of the different connection possibilities shall be submitted to OSINERGMIN by the applicant to determine the most efficient technical solution.

The participation of OSINERGMIN shall guarantee and enforce compliance with the legal principle of open access to transmission and distribution networks. An interconnection mandate establishes the conditions under which the interconnection shall take place. The parties usually prefer to reach an agreement establishing those conditions. However, in cases where an agreement is not feasible due to the pre-existence of previous interconnection commitments with other companies, OSINERGMIN has been willing to grant new interconnection mandates as long as there is available capacity.

Tariff Regime

The SGT is compensated through the tariff base, which is the authorized annual remuneration for facilities belonging to the SGT. The tariff base is established in annual amounts and includes the following: (i) remuneration of investments (including adjustments), which is calculated based on a 30-year recovery period applying a 12% rate of return, (ii) efficient operating and maintenance costs, and (iii) the liquidation of imbalances between the authorized tariff base for the previous year and the proceeds obtained during that year.

The tariff base will be paid through the (i) tariff income and (ii) the transmission toll. The tariff income is paid monthly by the electricity generation companies in proportion to their respective capacity income. The transmission toll is paid by the electricity generation companies based on their collection of the transmission toll paid by their respective customers pursuant to Article 26 of Law 28832 and Article 27 of the Transmission Rules, or Reglamento de Transmision, approved by the Supreme Decree No. 027-2007-EM.

The electricity generation companies are paid by customers via capacity charges and energy charges established in their respective supply contracts. These capacity charges include a transmission toll per unit of peak demand needed to cover the costs to be paid for the SGT.

The monthly payments to be made by electricity generation companies to the transmission companies are liquidated by the COES, in application of the tariffs determined by OSINERGMIN. A portion of the amount collected by the electricity generation companies from customers is allocated to the transmission companies that own facilities in the SGT. As such, electricity generation companies collect the money required to pay the SGT facilities from customers.

Non-regulated customers include large electricity consumers with a maximum annual power demand over 2,500 kW and customers with maximum annual power demands between 200 kW and 2500 kW that may choose to be regulated customers or not. Non-regulated customers may freely negotiate their energy prices with suppliers.

The SCT is remunerated on the basis of the annual average cost of the corresponding facilities approved by OSINERGMIN. The applicable tariffs and their respective actualization formulas are approved by OSINERGMIN every four years.

Penalties

The concessionaires must maintain certain quality, safety and maintenance standards of the facilities. The failure to meet the quality standards established by applicable industry regulations, such as the technical rules of quality for power services, approved by Supreme Decree No. 020-97-EM, and the National Power Code, may result in the imposition of penalties, fines and restrictions. In addition to these penalties, fines and restrictions, if our concession is terminated due to the breach of obligations under the Concession Agreements, the Peruvian Ministry of Energy may appoint an intervenor to supervise the operations related to the concession to ensure the continuity in the provision of the service, and the compliance with applicable laws and regulations.

112

Table of Contents

If a concessionaire suspends or interrupts the service for reasons other than regular maintenance and repairs, force majeure events, or failures caused by third parties, such concessionaire may be required to indemnify those who were affected for the damages caused by any such service interruption, in accordance with applicable regulations. In addition, the OSINERGMIN could impose penalties, including, among others, (a) admonishment, (b) successive fines, depending on the nature and effect of the interruption and its frequency, (c) temporary suspension of activities, and (d) definitive suspension of activities and the provisional administration of operations by an intervenor, if a termination event occurs and the Peruvian Ministry of Energy notifies of its desire to terminate the SGT Concession Agreement.

Also, OEFA (Agency of Environmental Evaluation and Control), the entity in charge of the supervision, inspection and sanction concerning environmental matters, may impose fines and corrective measures to the companies in case of violation of the environmental rules and regulations.

Electricity Legal Framework

The principal laws and regulations governing the Peruvian power sector, or the Power Legal Framework, are: (i) the Power Concessions Law (or Ley de Concesiones Electricas , PCL), approved by Law No. 25844, and its implementing rules (Supreme Decree No. 09-93-EM); (ii) the Law to Ensure the Efficient Development of Electricity Generation (or Ley para Asegurar el Desarrollo Eficiente de la Generacion Electrica ), approved by Law No. 28832, or Law No. 28832; (iii) the Transmission Rules (or Reglamento de Transmision ), approved by the Supreme Decree No. 027-2007-EM, or the Transmission Rules; (iv) the General Environmental Law (Law No. 28611); (v) the Rules for the Environmental Protection in Power Activities (Supreme Decree No. 029-94-EM); (vi) the Power Sector Antitrust Law (Law No. 26876) and its regulations (Supreme Decree No. 017-98-ITINCI); (vii) the Laws creating OSINERGMIN (Law No. 26734 and Law No. 28964); (viii) the OSINERGMIN Rules (Supreme Decree No. 054-2001-PCM); (ix) the Regulatory Agencies of Private Investment in Public Services Framework Law (Law No. 27332); and (x) the Legislative Decree that promotes investment in the generation of power through renewable resources (Legislative Decree No. 1002) and its regulations (Supreme Decree No. 012-2011-EM).

These laws regulate how to enter the electricity sector (applicable permits and licenses); the main obligations of the different participants of the electricity market (generators, transmission companies and distribution companies); remuneration systems for the different market participants; rights of electricity consumers and the attributions of the competent authorities.

Other relevant laws are: (i) the Public Consultation Law and its regulations (Law No. 29785 and Supreme Decree No. 001-2012-MC) for projects that may affect rights of indigenous and native communities and (ii) Law of National Heritage (Law 28296) and relevant regulations (among others, Supreme Decree No.003-2014-MC and Supreme Decree 011-2006-ED) for obtaining the CIRA which is issued by the Ministry of Culture, certifying there are no archaeological remains in an area. Prior to performance of any activity or construction works, titleholders shall obtain the corresponding CIRA.

Some of the main aspects of Peru’s regulatory framework concerning its power sector are: (i) the separation between the power generation, transmission and distribution activities; (ii) unregulated prices for the generation of power supplied to unregulated customers; (iii) regulated prices for the generation of power supplied to regulated customers; (iv) regulated prices applicable to transmission and distribution of power for both regulated and unregulated customers; and (v) the private administration of the SEIN, according to the principles of efficiency, cost reduction, guaranty of quality and reliability in the provision of services.

All entities that generate, transmit or distribute power to third parties in Peru, including self-generators and co-generators that sell their excess capacity and energy in the SEIN, are regulated by the Power Legal Framework.

Although significant private investments have been made in the Peruvian power sector and independent entities have been created to regulate and coordinate its oversight, the Peruvian government still retains ultimate oversight and regulatory control. In addition, the Peruvian government owns and controls various generation and distribution companies in Peru.

The Guaranteed Transmission System—SGT Concession Agreement

ATN and ATS (hereinafter, ABY Transmisión Sur), as concessionaires, have SGT Concession Agreements granted by the Peruvian government as a result of a public tender.

Under the SGT Concession Agreement, the Peruvian Ministry of Energy grants the concession necessary to construct, develop, own, operate, and maintain the transmission lines and substations comprising a project to provide electricity transmission services that has been included in the Peruvian transmission plan.

The SGT Concession Agreement must specify the works schedule of the project and the corresponding guaranties of compliance. It also specifies the causes of termination of the agreement. The SGT concessionaires are not obliged to pay the grantor any consideration for the SGT Concession Agreement.

Under the SGT Concession Agreement, the concessionaire shall build the lines and be responsible for their operation and maintenance. The recovery of the investment during the term of the contract (30 years) is guaranteed thereunder. The concessionaire owns the transmission assets during the term of the contract. Upon expiry of the contract the assets return to the state, which shall call a new tender if the lines are required at such time for the operation of the system.

In addition to the SGT Concession Agreement, the SGT concessionaire should obtain from the Peruvian Ministry of Energy a Definitive Concession, or the Definitive Concession, which entitles such concessionaire to develop the activity of electricity transmission. The Definitive Concession will be granted for the term of the SGT Concession Agreement, and under the terms and conditions of the latter (among others, the works schedule of the project).

Under the Definitive Concession, if the concessionaire requests it, the grantor shall impose easements on the lands required for the execution of the project in accordance with applicable laws, but the grantor does not assume the costs associated with such easements.

Under the SGT Concession Agreement upon request, the grantor is also required to use its best efforts to assist in obtaining licenses, permits, authorizations, concessions and other rights when the owner of the project complies with the legal requirements to obtain them and they are not granted on a timely basis by the competent authorities.

Revenues

The revenues of the project are established under the terms of the SGT Concession Agreement. In addition, the revenues of the project are funded by the users of electricity system.

In effect, the compensation for facilities that are part of the SGT is allocated to customers by OSINERGMIN according to the amounts of investment, operational and maintenance costs set forth in the SGT Concession Agreement. The SGT will receive monthly compensation from the generation companies that collect the tariff base from their customers. Their compensation will be paid on a monthly basis and these monthly payments are liquidated by the COES, following the tariffs established annually by OSINERGMIN.

As of the commercial operation date, the owner of a project receives the revenue from payments of the tariff base pursuant to the SGT Concession Agreement. The calculation of the tariff base is based on: (i) an amount which represents a return on investment, including operation and maintenance costs and (ii) the amount determined on May 1 of each year by OSINERGMIN, in order to compensate for any intra-year difference between the compensation we should have received in the immediately preceding tariff year in U.S. dollars and the amount actually paid in Peruvian soles, determined at the exchange rate published in the Official Gazette “El Peruano” on the last working day prior to the fifteenth day of the month following the relevant month for which the services were charged to the electricity generation companies.

Every year, before the beginning of the new tariff period, OSINERGMIN will recalculate and determine the tariff base in U.S. dollars for the period which starts from May 1 of such year to April 30 of the following year. This determination is approved in April of each year through a resolution published in the Official Gazette, “El Peruano.”

Regulation in Spain

On November 26, 1997, the European Union published a report, or White Paper, which outlined a strategy and a community-wide action plan aimed at doubling energy production from renewable energy sources in the European Union from 6% in 1996 to 12% by 2010. The White Paper proposed a number of measures to promote the use of renewable energy sources, including measures designed to provide renewable energy sources better access to the electricity market. The Kyoto Protocol, ratified by the EU and its Member States on May 31, 2002, imposed a target of reducing EU emissions of greenhouse gases by 8%.

Directive 2009/28/EC on the Promotion of the Use of Energy from Renewable Sources of the European Parliament and of the Council of the European Union, or the 2009 Renewable Energy Directive, set mandatory national overall targets for each Member State consistent with at least 20% of EU total energy consumption coming from renewable energy sources by 2020. In order to comply with these mandatory renewable energy targets, all EU Member States, including Spain, were required to develop a national action plan, called a National Renewable Energy Action Plan, or NREAP. Spain’s NREAP was issued on June 30, 2010 and sent to the European Commission.

In its NREAP, Spain set a target of 22.7% for primary energy consumption to be supplied by renewable energy sources and a target of 42.3% of total electricity consumption to be supplied by renewable energy sources by 2020.

In 2011, a new Renewable Energies Plan, referred to as REP 2011-2020, was developed by the European Parliament and the Council of the European Union under the 2009 Renewable Energy Directive that added a new target to the 2009 Renewable Energy Directive, a minimum of 10% of transportation energy consumption to be supplied from renewable energy sources in each Member State by 2020.

In Spain, these targets mean that energy from renewable sources should represent at least 20% of total energy consumption by 2020, consistent with the EU target, with a minimum of 10% of transportation consumption to be derived from renewable sources by that same year.

Article 3.3(a) of the 2009 Renewable Energy Directive states that in order to reach the targets set for 2020, Member States may apply support schemes and incentives for renewable energy. These support systems or incentives are different in each country, but the most common are:

•	Green certificates . Producers of renewable energy receive a “green certificate” for each MWh they generate, and suppliers of energy have an obligation to purchase part of the energy that they supply from renewable sources.

•	Investment grants and direct subsidies . These help defray the costs of installing renewable energy generation plants.

•	Tax exemptions or relief . These include ITCs, cash grants in lieu of tax credits and accelerated depreciation, among others.

•

System of direct support of prices . These include regulated tariffs and premiums and involve a regulatory guarantee to purchase energy generated by a renewable energy plant for an allotted period of time at a fixed tariff per kWh, for a maximum annual number of hours, so that the producer is ensured of a reasonable return on its investment.

Primary Rights and Obligations under the Electricity Act

The high penetration of production technologies from renewable energy sources, cogeneration and waste, included in the so-called special regime for the production of electrical energy, meant that their singular regulation linked to power and its technology had no object. On the contrary, it made it necessary for the regulation to contemplate these facilities in a manner analogous to that of the rest of the technologies that are integrated into the market, and in any case, that they are considered by reason of their technology and implications for the system, rather than by reason of their power, so that the differentiated concepts of ordinary and special regime were abandoned. For this reason, there is a unified regulation, without prejudice to the singular considerations that need to be established.

Notwithstanding the above, the Electricity Act eliminates specifies the priority access and dispatch criteria for electricity from renewable energy sources and high-efficiency cogeneration, in accordance with European Community directives and continues to recognize the following rights for producers with facilities that use renewable energy sources:

•

Priority off-take . Producers of electricity from renewable sources will have priority over conventional generators in transmitting to off takers the energy they produce over conventional generators under equal market conditions, without prejudice to the requirements relating to the maintenance of the reliability and safety of the national electricity system and based on transparent and non-discriminatory criteria, in terms to be determined by the Government in a regulatory manner.

•

Priority of access and connection to transmission and distribution networks . Without prejudice to the security of supply and the efficient development of the system, producers of electricity from renewable energy sources will have priority in obtaining access and connecting to the grid, subject to the terms set forth in the regulations, on the basis of objective, transparent and non-discriminatory criteria.

•

Entitlement to a specific payment scheme: In the case of existing facilities for the production of energy from renewable energy sources for which the specific remuneration system is recognised it is stablished a remuneration system based on the necessary participation in the market of these facilities, complemented by market income with a specific regulated remuneration that allows these technologies to compete on an equal conditions with the rest of the technologies on the market. This specific complementary remuneration will be sufficient to reach the minimum level necessary to cover the costs and enables them to compete on a level playing field with the other, non-renewable technologies on the market while achieving a reasonable return on investment. In case of new facilities, the Government can establish a specific remuneration and the granting of it would be via auction.

The significant obligations of the renewable energy electricity producers under the Electricity Act include, inter alia, a requirement to:

•	Offer to sell the energy they produce through the market operator even when they have not entered into a bilateral or forward contract and so are excluded from the bidding system managed by the market operator.

•	Maintain the plant’s planned production capacity. Power lines, which include connections with the transmission or distribution network and transformers, are considered part of the production facility.

•	Contract and pay the corresponding fees, whether directly or through their representatives, to the transmission or distribution companies to which the renewable energy facilities are connected in order for their power to be fed into the grid.

Additionally, the Royal Decree 413/2004 establishes the following relevant obligations for the renewable energy electricity facilities:

•	Having, prior to the beginning of discharge into the grid, the equipment for measuring electrical energy.

116

Table of Contents

•	The facilities must be registered in the Administrative Register of Electrical Energy Production Facilities under the Ministry of Industry.

•

Voltage dips: all facilities or groupings of photovoltaic facilities with an installed power greater than 2 MW, in accordance with the definition of grouping, shall be obliged to comply with the requirements for responding to voltage dips established by means of the corresponding operating procedure.

•

Control centres: all facilities with installed power greater than 5 MW, and those with installed power less than or equal to 5 MW but which form part of a grouping of the same subgroup of article 2 whose total sum of installed powers is greater than 5 MW, must be attached to a generation control centre.

•

Send of telemetric measurements: all facilities producing from renewable energy sources, cogeneration and waste with installed capacity greater than 1 MW, or less than or equal to 1 MW but which form part of a grouping of the same subgroup whose total installed capacity is greater than 1 MW, must send telemetric measurements to the system operator in real time.

Compliance with these last three obligations will be a necessary condition for the receipt of the specific retribution regime and must be accredited before the body in charge of carrying out the settlements. Otherwise, only market revenues will be received, without prejudice to the applicable sanctioning regime.

Permits and authorisations

The Electricity Act and the Royal Decree 1955/2000 generally require in terms of the promotion, construction and operation of facilities for the production of energy from renewable energy sources the obtaining of the following administrative authorisations:

•	Prior Administrative authorization ( Autorización Administrativa Previa ), which refers to the preliminary project of the installation as a technical document that will be processed, where appropriate, together with the environmental impact study.

•	Approval of the execution project ( Autorización Administrativa de Construcción ), which refers to the specific project of the facility and allows its owner to construct or establish it.

•	Operating permit ( Autorización Administrativa de Explotación ), which, once the project has been executed, allows the facilities to be energised and to proceed with their commercial exploitation.

Registration on Public Registers

The Electricity Act and Royal Decree 413/2014 require electricity generation facilities to be entered on the official register of electricity production plants maintained by the Ministry of Energy, Tourism and Digital Agenda.

The autonomous regions may keep their own registers of electricity generation plants they have authorized if such plants have a capacity of 50 MW or less. The registration details of these plants must be provided to the Ministry of Energy, Tourism and Digital Agenda electronically.

Solaben 2/3 and Solaben 1/6 are on the register of the autonomous region Extremadura and the Ministry of Energy, Tourism and Digital Agenda.

Solacor 1/2, PS10/20, Helioenergy ¹ ∕ 2 and Solnova 1/3/4 are on the register of the autonomous region of Andalusia and the Ministry of Energy, Tourism and Digital Agenda.

Helios 1/2 is on the register of the autonomous region Castilla La Mancha and the Ministry of Energy, Tourism and Digital Agenda.

To receive their facility-specific reimbursement, renewable energy facilities are required under the Electricity Act and Royal Decree 413/2014 to be recorded on a new register the RRRE . Unregistered plants will only receive the pool price.

117

Table of Contents

The first transitional provision of Royal Decree 413/2014 states that power plants based on renewable sources recognized under the previous economic regime, as in the case of Solaben 2/3, Solacor ½, PS10/20 will be automatically included in the RRRE.

Change of Compensation System Applicable to Solar Power Plants

Royal Decree-law 9/2013 introduced a change in the payment system applicable to new and existing electricity production facilities using renewable energy sources to guarantee the financial stability of the electric system. The purpose of Royal Decree-law 9/2013, which entered into force on July 14, 2013, was to adopt a series of measures to ensure the sustainability of the electric system and to combat the shortfalls between electricity system revenues and costs, referred to as the tariff deficit.

The measures adopted were focused primarily on the following areas: (i) the legal and financial regime for existing electricity production facilities using renewable energy sources, co-generation and residual waste; (ii) the remuneration regime for transport and distribution activities; (iii) Spain’s guarantee of the securitization fund to cover the tariff deficit; and (iv) certain aspects related to capacity payments, assumption of the cost of the subsidized tariff and a review of access charges.

Royal Decree-law 9/2013 established an entirely new remuneration system, abolishing the remuneration system based on a regulated tariff applicable to electricity production facilities using renewable energy sources (including facilities in operation at the time that Royal Decree-law 9/2013 entered into force).

Prior to the adoption of Royal Decree-law 9/2013, electricity production facilities using renewable energy sources received revenues tied to their electricity produced according to their power output. This involved receiving feed-in tariffs, in €/kWh, that were split into two components: (i) the pool price of electricity and (ii) an equivalent premium, consisting of the difference between the pool price and the set feed-in tariff for each type of plant (feed in tariff = pool price + equivalent premium). This revenue was received for a maximum annual number of hours and for a pre-determined number of years, depending on the technology used in each case. For any additional hours produced, producers received the pool price.

The repealed economic scheme was applied on a transitional basis until new provisions were approved to fully implement the new remuneration system. Settlements made after July 14, 2013 were made in accordance with the previous regime until the new implementing regulations have been adopted. However, following the implementation of these new regulations, payments made during this interim period were recalculated in accordance with the new regulations. The difference between the amounts received under the prior regime and those calculated under the new regime were deducted from the first nine settlements that followed the approval of the new implementing regulations.

Current System

According to Royal Decree 413/2014, producers receive (i) the pool price for the power they produce and (ii) a specific remuneration.

A specific remuneration system is established to encourage the production of energy from renewable energy sources, high-efficiency cogeneration and waste, which may be received by the facilities in addition to their corresponding remuneration for their participation in the electricity production market through any of their contracting modalities.

This remuneration system shall apply to production facilities using renewable energy sources, high-efficiency cogeneration and waste that do not reach the minimum level necessary to cover the costs that allow them to compete on an equal footing with the rest of the technologies on the market, obtaining a reasonable return, referring to the standard installation that is applicable in each case.

The granting of this specific remuneration system for new facilities shall be established by means of competitive competition procedures that shall conform to the principles of transparency, objectivity and non-discrimination.

In order to determine the specific remuneration system applicable in each case, each installation, depending on its characteristics, will be assigned a standard installation (which will be established according to technology, installed power, age, electrical system, etc.).

118

Table of Contents

The specific remuneration of each installation will be obtained from the remuneration parameters of the corresponding standard installation and from the characteristics of the installation itself.

For the calculation of the remuneration parameters of the standard installation, the values resulting from the competitive competition procedure shall be applied.

This specific remuneration system shall consist of:

A remuneration term per unit of installed power, which shall be called investment remuneration (Rinv) and shall be expressed in €/MW. To determine this parameter, the standard value of the initial investment resulting from the competitive tendering procedure established to grant the specific remuneration system to each installation will be considered. For the calculation of the annual income from the remuneration for the investment of an installation, the remuneration for the investment (Rinv) of the associated typical installation shall be multiplied by the power entitled to the specific remuneration system, without prejudice to the correction according to the number of equivalent hours of operation.

A remuneration term for the operation, which shall be called remuneration for the operation (Ro) and shall be calculated in accordance with the provisions of Article 17 of the Royal Decree 413/2014, expressed in €/MWh. In order to calculate the income from the remuneration for the operation of an installation, the remuneration for the operation (Ro) of the associated typical installation shall be multiplied, for each settlement period, by the energy sold on the production market in any of its forms of contracting in said period, attributable to the fraction of power entitled to a specific remuneration system, without prejudice to the correction based on the number of equivalent hours of operation.

For solar thermal plants, electrical energy attributable to the use of other fuels shall be excluded. The production of energy from the support fuel of solar thermal plants may not exceed 12 per cent of the total electricity production to be entitled to receive the specific remuneration system. The repetition of this non-compliance is reason for the cancellation of the inscription in the RRRE.

To calculate the energy attributable to the fraction of power entitled to a specific remuneration system, the corresponding energy shall be multiplied by the ratio resulting from dividing the power entitled to a specific remuneration system by the installed power.

In order to determine the power entitled to the specific remuneration system of a facility, the value of the power registered for this purpose in the register of the specific remuneration system in operation for said facility shall be taken as the value of the power registered for this purpose in the register of the specific remuneration system in operation for said facility.

For the granting of the specific remuneration system, the conditions, technologies or group of specific facilities that may participate in the competitive competition mechanism shall be established by royal decree.

Subsequently, by order of the Minister of Industry, Energy and Tourism, with the prior agreement of the Government’s Delegate Committee for Economic Affairs, the remuneration parameters corresponding to the type of reference facilities that are the object of the competitive bidding mechanism shall be established, as well as the terms in which it shall be developed. The granting of this specific remuneration system for existing facilities is regulated in the first transitory provision of RD 413/2014, that establishes that they will be automatically registered on a date to be determined by order of the Minister of Industry, Energy and Tourism. In any case, it contemplates the possibility of requesting the modification of the inaccuracies that could contain the data of the registry after the referred automatic inscription.

As established in Order IET/1168/2014, of 3 July, the existing facilities were automatically registered in the RRRE on 9 July 2014. In order to determine the information required for automatic registration in the RRRE, the information included in the “ Settlement System ” at the time of registration has been taken into account or, for those facilities not yet included in said System, that of the remuneration pre-allocation register.

It should be borne in mind that for the purposes of the liquidation of the specific remuneration regime (former primacy special regime), renewable facilities must be registered in the liquidation system of the CNMC. In order for an installation to be registered in said Settlement System, it must be operating and registered in the well-deserved Register. Thus, the automatic inscription in the RRRE has been carried out in a state of pre-allocation or in a state of exploitation, in accordance with the following:

119

Table of Contents

Those facilities which, at the time of registration, although having recognised primary remuneration, were not registered in the settlement system, i.e. those facilities which, although having recognised primary remuneration because they were registered in the corresponding pre-allocation register when RD-Law 9/2013 came into force, were not included in the Settlement System on 9 July 2014, as they were not operating or definitively registered in Registro de Instalaciones de Proucción en Régimen Especial (“RAIPRE”) , have been registered in a pre-allocation state. In this regard, the information contained in the remuneration pre-allocation register has been taken into account for registration.

b)	Those facilities which, at the time of registration, were registered in the settlement system, i.e. operating and definitively registered in the RAIPRE on 9 July 2014, have been registered in a state of operation.

Specifically, in accordance with the sixth additional provision of RD 413/2014, so that the facilities registered in the RRRE in a state of pre-allocation under the first transitory provision may be registered in the RRRE in a state of operation, it is an essential requirement that the installation be definitively registered in the RAIPRE and start evacuating energy prior to the given deadline, that is, within the maximum period applicable to them for this purpose (generally thirty-six months) from the date of notification of the resolution by which they were registered in the pre-allocation of remuneration register.

Payment Factors for Solar Power Plants

The payment system applicable for each plant is based on various criteria considered by the Ministry Energy, Tourism and Digital Agenda and includes the specific technology used, amount of power produced relative to operating costs, age of the facility and any other differentiating factor deemed necessary to consider in applications of the payment system.

Revenue Order recognizes six types of solar thermal plants: (i) parabolic trough collectors without a storage system, (ii) parabolic trough collectors with a storage system, (iii) central or tower receivers without a storage system, (iv) central or tower receivers with a storage system, (v) linear collectors and (vi) solar-biomass hybrids.

To determine the payment system applicable to each plant, the following factors are considered:

•	Net investment value . This consists of a standard amount per MW for each type of plant, calculated by the method set out in Royal Decree 413/2014, which is the amount invested in the plant and not depreciated as of July 14, 2013.

•	Useful life of the plant . For solar thermal plants this is 25 years and for fhotovoltaic plants this is 30 years.

•	Return on investment . Considering the net asset value determined on the basis of a standard cost per MW built, an amount is set per unit of power, which enables investment costs that cannot be recovered through the pool price to be recouped over the useful life of the plant.

•

Operating remuneration . An amount is set per unit of power and hour that, added to the pool price, enables the producer to recoup all the plant’s operating and maintenance costs. Operating expenses include the cost of land, electricity, gas and water bills, management, security, corrective and preventive maintenance, representation costs, the Spanish tax on special immovable properties, insurance, applicable generation charges and a generation tax which is equal to 7% of total revenue.

•	Maximum number of operating hours . A maximum number of hours is set for which each plant type can receive the operating remuneration.

•	Operating threshold . Plants must operate for more than a set number of hours per year to receive the return on investment and operating remuneration.

•	Minimum operating hours . Plants that cross the operating threshold but operate for fewer hours than the annual minimum hours receive a lower remuneration.

On February 22, 2017, after the end of the first half-period, the Ministry of Energy, Tourism and Digital Agenda published the Updated Parameters Order, updating the remuneration parameters of the standard facilities applicable to registered power generation facilities from renewable energy sources, cogeneration and waste during the regulatory half-period running from January 1, 2017 to December 31, 2019 as set forth in the table below.

Note:—

(1)	According to the Royal Decree 413/2014.

Regulatory Periods

Payment criteria are based on prevailing economic conditions in Spain, demand for electricity and reasonable profits for electricity generation activities and can be revised every three or six years. The Royal Decree 413/2014 establishes statutory periods of six years, with the first statutory period running from July 14, 2013 (the date of entry into force of Royal Decree-law 9/2013) to December 31, 2019. Each statutory period is divided into two statutory half-periods of three years. The first such half-period runs from July 14, 2013 to December 31, 2016.

This “statutory period” mechanism aims to set forth how and when the Ministry of Energy, Tourism and Digital Agenda is entitled to revise the different payment factors used to determine the specific remuneration to be received by the standard facilities.

At the end of each statutory half-period (three years) the Ministry of Energy, Tourism and Digital Agenda may revise (i) the electricity market price estimates and (ii) the adjustment value for electricity market price deviations in the preceding statutory half-period.

In this regard, the Updated Parameters Order updates the remuneration parameters of the standard facilities, for the regulatory half-period between 1 January 2017 and 31 December 2019, and the approval of the estimated market price for each year of said half-period (which is estimated in 42.84 €/MWh, 41.54 €/MWh and 41.87 €/MWh, respectively, for the years 2017, 2018 and 2019).

Reasonable Rate of Return

According to article 14 of the Electricity Act, the remuneration system shall not exceed the minimum level necessary to cover the costs that allow production facilities from renewable energy sources, high-efficiency cogeneration and waste to compete on an equal level with the other technologies on the market and that allows reasonable return to be obtained in relation to the standard installation in each applicable case. This reasonable return will be, before tax, on the average secondary market yield of the 10-year government treasury note by applying the appropriate differential.

121

Table of Contents

According to the Tenth Additional Provision of the Electricity Act, for production activities from renewable energy sources, cogeneration and waste with a specific remuneration system, the first regulatory period will begin on the date of entry into force of Royal Decree-Law 9/2013, of 12 July. In this period, the value on which the profitability of the reference rate projects will revolve for the competitive competition procedures, before taxes, will be the average secondary market yield for the three months prior to the entry into force of Royal Decree-Law 9/2013, of 12 July, of the 10-year State Obligations increased by 300 basic points.

Annex III of the Revenue Order specifies that the 10-year average yield for the 10-year bond is 4.398%, which, increased by 300 bps, results in 7.398% per annum.

Under no circumstances will amounts received by producers for electricity generated before July 14, 2013 be required to be returned or reimbursed under the new system.

Before the start of a new regulatory period, a revised reasonable return can be established for each plant type, calculated as the average yield on Spanish government 10-year bonds on the secondary market in the 24 months through the month of May preceding the new regulatory period, plus a spread.

This spread is based on the following criteria:

•	Appropriate profit for this specific type of renewable electricity generation and electricity generation as a whole, considering the financial condition of the Spanish electricity system and Spanish prevailing economic conditions; and

•	Borrowing costs for electricity generation companies using renewable energy sources with regulated payment systems, which are efficient and well run, within Europe.

The next regulatory period will begin on January 1, 2020.

On July 27, 2018, CNMC (the regulator for the electric system in Spain) issued a draft proposal for the calculation of the reasonable rate of return for the regulatory period 2020-2025. The draft reasonable rate of return proposed by CNMC was 7.04%. On November 2, 2018, CNMC issued its final report with a proposed reasonable rate of return of 7.09%. In December 2018 the government issued a draft project law proposing a reasonable rate of return of 7.09%. This draft also contemplates the possibility of maintaining the current reasonable rate of return for certain assets under certain circumstances for two consecutive regulatory periods. This draft is non-binding, open to comments subject to a long approval process and would have to be approved by the Spanish parliament prior to its effectiveness. In addition, since elections are scheduled in April in Spain, the draft may not be approved.

Funding the Tariff Deficit

The Electricity Act also states that from January 1, 2014, tariff deficit amounts would no longer be paid for, as they had been previously, by the five major Spanish utilities. Instead, they will be paid by the companies that receive “regulated payments,” including distributors, transportation companies, producers of electricity from renewable plants, companies receiving capacity payments and others. Each of these entities will temporarily fund the tariff deficit in proportion to the costs that they represent for the electricity system in a given year and can recover these contributions in the following five years, plus interest at a market rate.

According to the Electricity Act, tariff deficit cannot exceed 2% of the estimated system revenues for each year. Furthermore, the accumulated debt due to previous years’ deficit cannot exceed 5% of the estimated system revenues for that period. If these thresholds are exceeded, the Spanish government is forced to review the access fees so that the system revenues increase accordingly.

Access Fee

Royal Decree-law 14/2010 was passed in order to eliminate the shortfalls between electricity system revenues and costs, referred to as the tariff deficit in the electricity sector.

The First Transitional Provision of Royal Decree-law 14/2010 provided that the owners of electricity production facilities pay a fee for access to the grid to the transmission and distribution companies (this access previously having been provided at no cost) from January 1, 2011. During the interim period, the access fee payable is: (i) calculated at €0.5 per MWh delivered to the network or (ii) any other amount that the Ministry of Energy, Tourism and Digital Agenda establishes.

122

Table of Contents

Royal Decree 1544/2011 implemented the Sole Transitional Provision of Royal Decree 14/2010 and confirmed the interim access fee imposed on electricity producers (€0.5 per MWh), subject to the adoption of a final method for calculating the access fee.

Electricity Sales Tax

On December 27, 2012, the Spanish Parliament approved Law 15/2012, which became effective on January 1, 2013. The aim of Law 15/2012 is to try to combat the problem of the so-called tariff deficit, which reached approximately €28 billion as of December 2013.

Law 15/2012, as amended, provides for an electricity sales tax which is levied on activities related to electricity production. The tax is triggered by the sale of electricity and affects ordinary energy producers and those generating power from renewable sources. The tax, a flat rate of 7%, is levied on the total income received from the power produced at each of the facilities, which means that every calendar year, solar power plants will be required to pay 7% of the total amount which they are entitled to receive for production and incorporation into the electricity system of electric power, measured as the net output generated.

However, the Royal Decree-Law 15/2018 includes a six-month exemption from this tax, for the electricity produced and incorporated into the electricity system, coinciding with the months of greatest demand and highest prices in the wholesale electricity markets. This entails modifying the calculation of the tax base and of the fractioned payments regulated in the tax regulations, in the following manner:

•

For fiscal year 2018 the taxable base of the Tax on the Value of the Production of Electrical Energy will be made up of the total amount corresponding to the taxpayer for the production and incorporation into the electrical system of electrical energy, measured in plant bars, for each installation in the tax period reduced by the remuneration corresponding to the electricity incorporated into the system during the last calendar quarter.

The fractioned payments for the last quarter shall be calculated on the basis of the value of the electric power production in plant bars made during the tax period reduced by the remunerations corresponding to the electricity incorporated into the system during the last calendar quarter, applying the tax rate provided for in Article 8 of Law 15/2012 and deducting the amount of the fractioned payments previously made.

•

For fiscal year 2019, the taxable base of the Tax on the Value of the Production of Electrical Energy will be made up of the total amount corresponding to the taxpayer for the production and incorporation into the electrical system of electrical energy, measured in plant bars, for each installation in the tax period reduced by the remuneration corresponding to the electricity incorporated into the system during the first calendar quarter.

However, we expect the remuneration to be adjusted for the lower tax paid in these two quarters when remuneration parameters are reviewed, so that no impact is expected.

The fractioned payments shall be calculated on the basis of the value of the electricity production in plant bars from the beginning of the tax period until the end of the three, six, nine or twelve months referred to in the previous section, reduced by the amount of the remuneration corresponding to the electricity incorporated into the system during the first calendar quarter, applying the tax rate provided for in Article 8 of Law 15/2012 and deducting the amount of the fractioned payments previously made.

Tax Incentive of Accelerated Depreciation of New Assets

Under provisions of the Spanish Corporate Income Tax Act, tax-free depreciation is permitted on investments in new material assets and investment properties used for economic activities acquired between January 1, 2009 and March 31, 2012. Taxpayers who made investments during such period and have amounts pending to be deducted for this concept may apply such amounts with certain limitations.

Taxpayers who made or will make investments from March 31, 2012 through March 31, 2015 in new material assets and investment properties used for economic activities are permitted to take accelerated depreciation for those assets subject to certain limitations. The accelerated depreciation is permitted if:

•	40% of the tax base before the amortization or depreciation and before the offset of tax loss carryforwards for taxpayers (subject to requirements to keep up employment levels); or

•	20% of the tax base before the amortization or depreciation and before the offset of tax loss carryforwards for taxpayers (without employment requirements).

Most of the investment in our Spanish assets was undertaken within the regime that applied between January 1, 2009 and March 31, 2012.

These limitations do not apply in respect of companies that meet the requirements set forth in article 108.1 of the Spanish Corporate Income Tax Act related to the special rules for enterprises of a reduced size.

ITEM 5.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

The following discussion should be read together with, and is qualified in its entirety by reference to, our Annual Consolidated Financial Statements. The following discussion contains forward-looking statements that reflect our plans, estimates and beliefs, which are based on assumptions we believe to be reasonable. Our actual results could differ materially from those discussed in these forward-looking statements as a result of various factors, including those set forth under “Item 3.D—Risk Factors” and elsewhere in this annual report.

A.	Operating Results

Overview

As of the date of this annual report, we own or have an interest in a portfolio of high-quality and diversified assets in terms of type of asset, technology and geographic footprint. Our portfolio consists of 24 assets with 1,496 MW of aggregate renewable energy installed generation capacity, 300 MW of efficient natural gas-fired power generation capacity, 10.5 M ft3 per day of water desalination and 1,152 miles of electric transmission lines.

We are focused on high-quality, long-life facilities as well as long-term agreements that we expect will produce stable, long-term cash flows. We intend to grow our cash available for distribution and our dividend to shareholders through organic growth and by acquiring new assets and/or businesses where revenues are not fully contracted.

126

Table of Contents

We believe we can achieve organic growth through the optimization of the existing portfolio, escalation factors in many of our assets and the expansion of current assets, particularly our transmission lines, to which new assets can be connected. We currently own three transmission lines in Peru and four in Chile. We believe that current regulations in Peru and Chile provide a growth opportunity by expanding transmission lines to connect new clients. Additionally, we should have repowering opportunities in certain existing generation assets once their contracted life has expired.

Additionally, we intend to enter into similar agreements or enter into partnerships with other developers or asset owners to acquire assets in operation or under construction. We may also invest directly or through investment vehicles with partners in assets under development or construction, ensuring that such investments are always a small part of our total investments. Finally, we also expect to acquire assets from third parties leveraging the local presence and network we have in the geographies and sectors in which we operate.

2018 acquisitions

In February 2018, we completed the acquisition of a 4 MW mini-hydroelectric power plant in Peru for a cash consideration of approximately $9 million. The plant reached COD in 2012. It has a fixed-price concession agreement denominated in U.S. dollars with the Ministry of Energy of Peru and the price is adjusted annually in accordance with the U.S. Consumer Price Index. See “Item 4.B —Business Overview—Our Operations—Renewable Energy” for a description of such assets.

127

Table of Contents

In addition, in October 2018, we reached a preliminary agreement for another expansion of ATN consisting of certain transmission assets in Peru. The assets are currently in operation and will receive dollarized revenues under a long-term contract. Our total investment is expected to be approximately $20 million. The final purchase agreement has not been signed yet.

In January 2019 we entered into an agreement with Abengoa under the Abengoa ROFO Agreement for the acquisition of Befesa Agua Teneés, S.L.U., a holding company which owns a 51% stake of Tenes, a water desalination plant in Algeria, similar in several aspects to our Skikda and Honaine plants. Tenes has a capacity of 7 million cubic feet per day to provide water under a water purchase agreement in place with Sonatrach and ADE (Algerienne des Eaux), with a remaining term of approximately 22 years. It has been in operation since 2015. The tariff structure is based upon plant capacity and water production and price is adjusted monthly based on indexation mechanisms that include local inflation, U.S. inflation and the exchange rate between the U.S. dollar and local currency. Closing of the acquisition is subject to conditions precedent, including the approval by the Algerian administration. At this stage, we cannot guarantee that we will obtain this approval nor the expected timing of such approval. The price agreed for the equity value is $24.5 million, of which $19.9 million was paid in January 2019 as an advanced payment and the rest is expected to be paid once the conditions precedent are fulfilled. If all the conditions precedent were not fulfilled by September 30, 2019, the advanced payment shall be progressively reimbursed by Abengoa through a full cash-sweep of all the dividends to be received and in any case no later than September 30, 2031, together with an annual 12% interest.

Recent Developments

On February 13, 2019, our board of directors formed a strategic review committee (the “Special Committee”) with the purpose of evaluating a wide range of strategic alternatives available to us to optimize our value and to improve returns to shareholders. The Special Committee has been mandated to review a wide range of alternatives and to make proposals in this regard to the board of directors. We have not set a timetable for the conclusion of the review of alternatives. There can be no assurance that a review of alternatives will result in any change or any other outcome.

128

Table of Contents

Our solar assets in Spain receive revenues under a regulation based on a reasonable rate of return which is subject to review every six years, with the first regulatory period ending at the end of 2019. On July 27, 2018, CNMC (the regulator for the electric system in Spain) issued a draft proposal for the calculation of the reasonable rate of return for the regulatory period 2020-2025. The draft reasonable rate of return proposed by CNMC was 7.04%. On November 2, 2018, CNMC issued its final report with a proposed reasonable rate of return of 7.09%. In December 2018 the government issued a draft project law proposing a reasonable rate of return of 7.09%. This draft also contemplates the possibility of maintaining the current reasonable rate of return for certain assets under certain circumstances for two consecutive regulatory periods. This draft is non-binding, open to comments subject to a long approval process and would have to be approved by the Spanish parliament prior to its effectiveness. In addition, since elections are scheduled in April in Spain, the draft may not be approved.

On February 26, 2019, our board of directors approved a dividend of $0.37 per share, which represents an increase of 19% from the fourth quarter of 2017. The dividend is expected to be paid on March 22, 2019, to shareholders of record as of March 12, 2019.

K ey Metrics

We regularly review a number financial measurements and operating metrics to evaluate our performance, measure our growth and make strategic decisions. In addition to traditional IFRS performance measures, such as total revenue, we also consider Further Adjusted EBITDA. Our management believes Further Adjusted EBITDA is useful to investors and other users of our financial statements in evaluating our operating performance because it provides them with additional tools to compare business performance across companies and across periods. EBITDA is widely used by investors to measure a company’s operating performance without regard to items such as interest expense, taxes, depreciation and amortization, which can vary substantially from company to company depending upon accounting methods and book value of assets, capital structure and the method by which assets were acquired. Further Adjusted EBITDA is widely used by other companies in the same industry.

Note:—

Further Adjusted EBITDA is calculated as profit/(loss) for the year attributable to the parent company, after adding back loss/(profit) attributable to non-controlling interest from continued operations, income tax, share of profit/(loss) of associates carried under the equity method, finance expense net, depreciation, amortization and impairment charges of entities included in the Annual Consolidated Financial Statements, and dividends received from our preferred equity investment in ACBH. Further Adjusted EBITDA for the year ended December 31, 2016 and for the first quarter of 2017 includes compensation received from Abengoa in lieu of ACBH dividends. Further Adjusted EBITDA is not a measure of performance under IFRS as issued by the IASB and you should not consider Further Adjusted EBITDA as an alternative to operating income or profits or as a measure of our operating performance, cash flows from operating, investing and financing activities or as a measure of our ability to meet our cash needs or any other measures of performance under generally accepted accounting principles. We believe that Further Adjusted EBITDA is a useful indicator of our ability to incur and service our indebtedness and can assist securities analysts, investors and other parties to evaluate us. Further Adjusted EBITDA and similar measures are used by different companies for different purposes and are often calculated in ways that reflect the circumstances of those companies. Further Adjusted EBITDA may not be indicative of our historical operating results, nor is it meant to be predictive of potential future results. See “Presentation of Financial Information—Non-GAAP Financial Measures.”

Factors Affecting the Comparability of Our Results of Operations

Acquisitions

The results of operations of each acquisition have been consolidated since the date of their respective acquisition. The acquisitions we have made during the last three years and any other acquisitions we may make from time to time, will affect the comparability of our results of operations.

Agreement to repurchase long-term operation and maintenance variable services

The operation and maintenance services received in some of our Spanish solar assets include a variable portion payable in the long-term. On April 26, 2018, we purchased from Abengoa the long-term operation and maintenance payable accrued until December 31, 2017, which amounted to $57.3 million. We paid $18.3 million for this payable and as a result, in the second quarter of 2018, we recorded a one-time gain for the difference, amounting to $39.0 million.

Project debt refinancing

In the second quarter of 2018, we refinanced Helios 1/2 and Helioenergy 1/2. Under the new IFRS 9, when there is a refinancing with a non-substantial modification of the original debt, there is a gain or loss recorded in the income statement. This gain or loss is equal to the difference between the present value of the cash flows under the original terms of the former financing and the present value of the cash flows under the new financing, each discounted at the original effective interest rate. As a result, we recorded non-cash financial income of $36.6 million in the second quarter of 2018.

Exchangeable Preferred Equity Investment in Abengoa Concessões Brasil Holding

Since our IPO until 2017 we held an exchangeable preferred equity investment in ACBH. See “Item 4.B—Business Overview— Electric Transmission—Exchangeable Preferred Equity Investment in Abengoa Concessões Brasil Holding.”

In the third quarter of 2016, we entered into an agreement with Abengoa relating to the ACBH preferred equity investment among other things with the following main consequences:

·	We were recognized as the legal owner of the dividends that we retained from Abengoa and these amounts were recorded as Further Adjusted EBITDA in 2017 ($10.4 million) and in 2016 ($28.0 million).

Abengoa recognized a non-contingent credit corresponding to the guarantee it provided regarding the preferred equity investment in ACBH, subject to restructuring. On October 25, 2016, we signed Abengoa’s restructuring agreement and agreed, subject to implementation of the restructuring, to receive 30% of the amount owed to us in the form of tradable notes to be issued by Abengoa. The remaining 70% owed to us was agreed to be received in the form of equity in Abengoa.

131

Table of Contents

As a result, we waived, as agreed, all our rights under the ACBH agreements, including our right to further retain dividends payable to Abengoa. As a result, in March 2017, we wrote off the accounting value of the ACBH instrument, which amounted to $30.5 million as of December 31, 2016. We no longer own any shares in ACBH and we sold entirely all the debt and equity instruments we received from Abengoa.

Impairment

In the fourth quarter of 2018, we recorded an impairment of $42.7 million relating to Solana due to the underperformance of the plant in the past few years and the uncertainty of the production level expected in the future. See Note 6 of our Annual Consolidated Financial Statements.

Additionally, as a result of the legal situation of ACBH since 2016 referred to above, the results for the year ended December 31, 2016 were impacted by the impairment of our preferred equity investment in ACBH of $22.1 million. We did not record any additional impairment in 2017 since we wrote-off the accounting value of this instrument following the agreement reached with Abengoa as “Other financial expense.” See “ Item 4.B—Business Overview — Electric Transmission—Exchangeable Preferred Equity Investment in Abengoa Concessões Brasil Holding.”

In addition, in the fourth quarter of 2016, we recorded an impairment of $20.3 million in our wind assets in Uruguay.

Change of ownership under Section 382 of the Internal Revenue Code

Under section 382 of the IRC, an “ownership change” would occur if our direct and indirect “5-percent shareholders,” as defined under Section 382 of the IRC, collectively increased their ownership in us by more than 50 percentage points over a rolling three-year period. In 2017, as a result of Abengoa’s restructuring and the change in its shareholder base, we experienced a change of ownership as defined under section 382 of the IRC, which caused an annual limitation on the use of the pre-ownership change U.S. NOLs generated by our U.S. solar assets equal to the equity value of the asset immediately before the ownership change, multiplied by the long-term tax-exempt rate for the month in which the ownership change occurs, and increased by a certain portion of any “built-in-gains.” In addition, because we had recorded tax credits for the U.S. tax loss carryforwards in the past, the limitation to our ability to use net operating loss carryforwards in the United States resulted in writing off tax credits previously recognized equal to $96 million in 2017. This one-time income tax expense did not have any cash impact in 2017.

U.S. Tax Reform

In December 2017, the TCJA was enacted in the United States. The measures adopted include, among other measures, a decrease in the federal corporate tax rate from 35.0% to 21.0% effective January 1, 2018. We therefore adjusted the deferred tax assets and liabilities of our U.S. entities using the new enacted corporate tax rate as of December 31, 2017, resulting in a one-time non-cash income tax expense of $19 million recorded in the consolidated income statement for the year ended December 31, 2017.

Factors Affecting Our Results of Operations

Interest rates

We incur significant indebtedness at the corporate and asset level. The interest rate risk arises mainly from indebtedness with variable interest rates.

Most of our debt consists of project debt. As of December 31, 2018, approximately 93% of our project debt has either fixed interest rates or has been hedged with swaps or caps.

To mitigate interest rate risk, we primarily use long-term interest rate swaps and interest rate options which, in exchange for a fee, offer protection against a rise in interest rates. We estimate that approximately 91% of our total interest risk exposure was fixed or hedged as of December 31, 2018. Nevertheless, our results of operations can be affected by changes in interest rates with respect to the unhedged portion of our indebtedness that bears interest at floating rates, which typically bears a spread over EURIBOR or LIBOR.

132

Table of Contents

Exchange rates

Our functional currency is the U.S. dollar, as most of our revenues and expenses are denominated or linked to U.S. dollars. All our companies located in North America, South America and Algeria have their PPAs, or concessional agreements, and financing contracts signed in, or indexed to, U.S. dollars. Our solar power plants in Spain have their revenues and expenses denominated in euros. As a result, revenues and expenses of Kaxu, our solar plant in South Africa, are denominated in South African Rand. Fluctuations in the value of the euro and the South African Rand may affect our operating results. Our strategy is to hedge cash distributions from our Spanish assets. We hedge the exchange rate for the distributions from our Spanish assets after deducting euro-denominated interest payments and euro-denominated general and administrative expenses. Through currency options, we have hedged 100% of our euro-denominated net exposure for the next 12 months and 75% of our euro-denominated net exposure for the following 12 months.

Impacts associated with fluctuations in foreign currency are discussed in more detail under “Item 11—Quantitative and Qualitative Disclosure about Market Risk—Foreign exchange rate risk.” In subsidiaries with functional currency other than the U.S. dollar, assets and liabilities are translated into U.S. dollars using end-of-period exchange rates; revenue, expenses and cash flows are translated using average rates of exchange. Although we hedge cash-flows in euros, fluctuations in the value of the euro in relation to the U.S. dollar may affect our operating results. Fluctuations in the value of the South African rand in relation to the U.S. dollar may also affect our operating results.

Apart from the impact of translation differences described above, the exposure of our income statement to fluctuations of foreign currencies is limited, as the financing of projects is typically denominated in the same currency as that of the contracted revenue agreement. This policy seeks to ensure that the main revenue and expenses in foreign companies are denominated in the same currency, limiting our risk of foreign exchange differences in our financial results.

In our discussion of operating results, we have included foreign exchange impacts in our revenue by providing constant currency revenue growth. The constant currency presentation is not a measure recognized under IFRS and excludes the impact of fluctuations in foreign currency exchange rates. We believe providing constant currency information provides valuable supplemental information regarding our results of operations. We calculate constant currency amounts by converting our current period local currency revenue using the prior period foreign currency average exchange rates and comparing these adjusted amounts to our prior period reported results. This calculation may differ from similarly titled measures used by others and, accordingly, the constant currency presentation is not meant to substitute for recorded amounts presented in conformity with IFRS as issued by the IASB nor should such amounts be considered in isolation.

Key Performance Indicators

In addition to the factors described above, we closely monitor the following key drivers of our business sectors’ performance to plan for our needs, and to adjust our expectations, financial budgets and forecasts appropriately.

Comparison of the Years Ended December 31, 2018 and 2017

The significant variances or variances of the significant components of the results of operations are discussed in the following section.

Revenue

Revenue increased by 3.5% to $1,043.8 million for the year ended December 31, 2018, compared to $1,008.4 million for the year ended December 31, 2017. The increase was primarily due to higher production at Kaxu in South Africa and at our solar plants in the United States as well as to the appreciation of the euro against the U.S. dollar. On a constant currency basis, revenue for the year ended December 31, 2018 would have been $1,024.4 million, representing an increase of 1.6% compared to the year ended December 31, 2017. In Kaxu, production was significantly higher for the year ended December 31, 2018 partially because the previous year was affected by a technical problem with the water pumps which was resolved during 2017. In the United States, revenues increased for the year ended December 31, 2018 compared to the previous year, due in part to a very good summer in terms of production.

The operation and maintenance services received by some of our Spanish solar assets include a variable portion payable in the long-term. On April 26, 2018, we purchased from Abengoa the long-term operation and maintenance payable accrued until December 31, 2017, which amounted to $57.3 million. We paid $18.3 million for this and as a result in the second quarter of 2018 we have recorded a one-time gain for the difference, amounting to $39.0 million. The increase was also due to the one-off payments to Solana from Abengoa in connection with the consent from the DOE. In the context of this agreement, Solana received an aggregate of $120 million of payments in December 2017 and March 2018. From an accounting perspective, as the payment resulted from Abengoa’s obligations under the EPC contract, most of the amounts received were recorded as reducing the asset value of Solana. The remainder, approximately $25 million, has been recorded in the income statement in 2018, partially increasing income from various services and partially reducing Other operating expenses. In addition, Solana received approximately $10 million from an insurance claim in the third quarter of 2018.

Grants represent the financial support provided by the U.S. government to Solana and Mojave and consist of ITC Cash Grants and an implicit grant related to the below market interest rates of the project loans with the Federal Financing Bank.

Raw materials and consumables used

Raw materials and consumables used decreased by 37.3% to $10.6 million for the year ended December 31, 2018, compared to $17.0 million for the year ended December 31, 2017, primarily due to fewer spare parts and consumables used at Solana and Mojave.

Employee benefits expenses

Employee benefit expenses decreased by 19.8% to $15.1 million for the year ended December 31, 2018, compared to $18.7 million for the year ended December 31, 2017, mainly due to a $4.7 million reversal of the accrual of our LTIP. The plan covered the three-year period 2016 to 2018 and is payable in March 2019 (see “Item 6.B Compensation”). Without this effect, employee benefit expenses would have increased slightly, mainly due to the appreciation of the euro against the U.S. dollar in 2018 compared to 2017, since a large part of our personnel costs are denominated in euros and due to an increase of our headcount in Peru and South Africa following termination of the local services agreements with Abengoa in these countries. As a result, we no longer pay any fee to Abengoa for these services.

Depreciation, amortization and impairment charges

Depreciation, amortization and impairment charges increased by 16.6% to $362.7 million for the year ended December 31, 2018, compared with $311.0 million for the year ended December 31, 2017 mainly due to the recognition of a $42.7 million impairment relating to Solana during the fourth quarter of 2018. The increase was also due in part to the appreciation of the euro against the U.S. dollar in 2018 compared to the same period during 2017 , (see Note 6 to our Annual Consolidated Financial Statements) which caused an increase in the depreciation and amortization of our Spanish assets when converted to U.S. dollars, as well as to the application of the new accounting standard IFRS 9 in effect since January 2018. The new accounting standard requires impairment provisions based on the expected credit losses on financial assets instead of incurred credit losses as was the case under IAS 39. These effects were partially offset by a decrease in the amortization of Solana arising from the reduction in the asset value resulting from the amount received from Abengoa as part of DOE’s consent.

Total		300.0		28.7	%		284.5		28.2	%

Other operating expenses increased by 5.5% to $300.0 million for the year ended December 31, 2018, compared to $284.5 million for the year ended December 31, 2017. The increase was mainly due to the higher operation and maintenance costs at ACT incurred in connection with major maintenance scheduled for the beginning of 2019. In ACT, the operation and maintenance costs increase in the quarters prior to a major maintenance. Operation and maintenance expenses also increased due to the appreciation of the euro against the US dollar in our solar assets in Spain, whose expenses are denominated in euros and converted to U.S. dollars at an average currency exchange rate for the year. Levies and duties decreased mainly due to a one-time provision for property taxes recorded at some plants in Spain in the second quarter of 2017 with no corresponding amount during the same period of 2018.

Operating profit

As a result of the above factors, operating profit increased by 6.5% to $487.9 million for the year ended December 31, 2018, compared with $458.0 million for the year ended December 31, 2017.

Financial income

Financial income increased to $36.4 million for the year ended December 31, 2018, compared to $1.0 million for the year ended December 31, 2017. The increase was due in part to non-cash financial income of $36.6 million resulting from the refinancing of Helios 1/2 and Helioenergy 1/2 in the second quarter of 2018. Under IFRS 9, when there is a refinancing with a non-substantial modification of the original debt, there is a gain or loss recorded in the income statement. This gain or loss is equal to the difference between the present value of the cash flows under the original terms of the former financing and the present value of the cash flows under the new financing, discounted both at the original effective interest rate.

Financial expense

The following table sets forth our financial expense for the years ended December 31, 2018 and 2017:

	Year ended December 31,
Financial expense	2018		2017
	$ in millions
Expenses due to interest:
Loans with credit entities		(256.7)		(253.7	)
Other debts		(100.1)		(137.6	)
Interest rates losses derivatives: cash flow hedges		(68.2)		(72.4	)
Total		(425.0)		(463.7	)

Financial expense decreased by 8.3% to $425.0 million for the year ended December 31, 2018, compared to $463.7 million for the year ended December 31, 2017. Financial expense in loans with credit entities increased mainly due to an increase in Libor denominated project debt, which was partially offset by a decrease in Interest rate losses in derivatives, caused by an increase in Libor.

The interest on other debts consisted of interest on the notes issued by ATS, ATN, ATN2, Atlantica Yield and Solaben Luxembourg and interests related to the investments from Liberty. In 2017 we updated the accounting model used to calculate this liability considering past underperformance of Solana and recorded a non-cash expense; in 2018 we also updated the model, which resulted in a lower non-cash expense, which explains the decrease in 2018.

“Other financial income/(expense), net” was a net expense of $8.2 million for the year ended December 31, 2018 compared to a net income of $18.4 million for the year ended December 31, 2017. The change resulted in part from the $10.4 million ACBH retained dividend compensation recorded in the first quarter of 2017 with no corresponding amount in 2018. We no longer own any shares in ACBH and will not retain any additional dividends. See “—Factors Affecting the Comparability of Our Results of Operations” above. In addition, the decrease in Other financial income was mainly due to the gain in 2017 resulting from the cancelation of the currency swap agreement with Abengoa with no corresponding amount in 2018.

Other financial losses include expenses from guarantees, letters of credit, wire transfers, other bank fees and other minor financial expenses.

Share of profit of associates carried under the equity method

Share of profit of associates carried under the equity method remained stable, amounting to $5.2 million in the year ended December 31, 2018 compared to $5.3 million in the year ended December 31, 2017. This includes mainly the income from Honaine, which we account for by the equity method.

Profit/(loss) before income tax

As a result of the previously mentioned factors, we reported a profit before income taxes of $97.9 million for the year ended December 31, 2018, compared to a profit before income taxes of $14.9 million for the year ended December 31, 2017.

Income tax

The effective tax rate for the periods presented has been established based on management’s best estimates. For the year ended December 31, 2018, income tax amounted to an expense of $42.6 million, with a profit before income tax of $97.9 million. For the year ended December 31, 2017, income tax amounted to a $119.8 million of expense, with a profit before income tax of $14.9 million. In 2017, we recorded a one-time income tax of $96 million mainly due to the change of ownership under Section 382 of the Internal Revenue Code. The effective tax rate differs from the nominal tax rate mainly due to permanent differences and tax losses for which we do not record a tax credit in some jurisdictions.

Profit attributable to non-controlling interests

Profit attributable to non-controlling interests was $13.7 million for the year ended December 31, 2018 compared to $6.9 million for the year ended December 31, 2017. The change was mainly due to higher profit at Kaxu, a project in which our partner holds a 49% stake and which reported a loss in 2017.

Profit / (loss) attributable to the parent company

As a result of the previously mentioned factors, profit attributable to the parent company was $41.6 million for the year ended December 31, 2018, compared to a loss of $111.8 million for the year ended December 31, 2017.

Comparison of the Years Ended December 31, 2017 and 2016

The significant variances or variances of the significant components of the results of operations are discussed in the following section.

Revenues

Revenues increased by 3.8% to $1,008.4 million for the year ended December 31, 2017, compared with $971.8 million for the year ended December 31, 2016. The increase was mainly due to higher revenue per MWh produced and higher production at our solar assets in Spain. The appreciation of the euro against the U.S. dollar for the year ended December 31, 2017 compared to the year ended December 31, 2016 also contributed to the increase. This was partially offset by reduced performance of Kaxu, our solar asset in South Africa, after the plant experienced technical problems. Additionally, ACT continued to deliver robust levels of production and availability. However, revenues from ACT slightly decreased due to the lower revenues in the portion of the tariff related to the operation and maintenance services, driven by lower operation and maintenance costs in 2017.

Other operating income	$ in millions
Grants		59.7		59.1

Other operating income increased by $15.3 million to $80.8 million for the year ended December 31, 2017, compared with $65.5 million for the year ended December 31, 2016. Income from various services increased due to insurance proceeds received in Kaxu and Solana of approximately $14 million.

Income classified as grants represents the financial support provided by the U.S. administration to Solana and Mojave consists of ITC Cash Grants and an implicit grant related to the below market interest rates of the project loans with the FFB. Grants remained stable for the years ended December 31, 2017 and 2016.

Raw materials and consumables used

Raw materials and consumables used decreased by $9.9 million to $17.0 million for the year ended December 31, 2017, compared with $26.9 million for the year ended December 31, 2016, primarily due to fewer spare parts and consumables used at Solana and Mojave.

Employee benefits expenses

Employee benefit expenses increased by $4.0 million to $18.7 million for the year ended December 31, 2017, compared with $14.8 million for the year ended December 31, 2016. The increase was mainly due to the transfer of employees previously employed by subsidiaries of Abengoa who were providing services to us under the support services agreement to our subsidiaries. The transfer occurred during the first six months of 2016 and the support service agreement was terminated in the second quarter of 2016.

Depreciation, amortization and impairment charges

Depreciation, amortization and impairment charges decreased by 6.6% to $311.0 million for the year ended December 31, 2017, compared with $332.9 million for the year ended December 31, 2016. The decrease was largely attributable to $20.3 million of impairment in our wind assets that was recorded in the fourth quarter of 2016 due to lower than expected wind resource in the previous two years.

Table of Contents

Other operating expenses increased by 9.3% to $284.5 million for the year ended December 31, 2017, compared with $260.3 million for the year ended December 31, 2016. The increase was largely due to higher costs recorded in Other expenses as well as Levies and duties which were partially offset by lower costs recorded in Operation and maintenance. Other expenses principally increased due to provisions for legal expenses in our U.S. assets. Levies and duties increased mainly due to $8.1 million of a one-time provision for property taxes recorded at certain plants in Spain. These cost increases were partially offset by the Operation and maintenance cost savings that resulted mainly from lower operation and maintenance expenses of ACT for the year ended December 31, 2017 compared to the year ended December 31, 2016, a year when ACT had scheduled major maintenance.

Operating profit

As a result of the above factors, operating profit increased by 13.8% to $458.0 million for the year ended December 31, 2017, compared with $402.4 million for the year ended December 31, 2016.

Interest rates losses derivatives: cash flow hedges		(72.4	)		(74.1	)
Total		(463.7	)		(408.0	)

Financial expense increased by 13.7% to $463.7 million for the year ended December 31, 2017, compared with $408.0 million for the year ended December 31, 2016. This increase was largely attributable to the increase of expenses due to interest on Other debts, mainly due to a one-time non-monetary expense of $50.1 million resulting from the update in the estimation of Liberty’s tax equity investment accounting value. Under IFRS, although the investment of Liberty is in ordinary shares, it does not qualify as equity and has been classified as a liability recorded in Grants and other liabilities measured at amortized cost in accordance with the effective interest method.

Financial expenses related to loans with credit entities increased mainly due the higher interest rate for the long-term Note Issuance Facility since February 2017 compared to the lower interest rate of the short-term tranche B of the Former Revolving Credit Facility, which was since paid off.

Interest on Other debts is primarily interest on the notes issued by ATS, ATN, ATN2, and Solaben 1/6 and the 2019 Notes.

Losses from interest rate derivatives designated as cash flow hedges correspond mainly to transfers from equity to financial expense when the hedged item is impacting the Annual Consolidated Financial Statements.

Other financial income, net increased to $18.4 million for the year ended December 31, 2017, from $8.5 million for the year ended December 31, 2016 due primarily to the gain resulting from the cancellation of the Currency Swap with Abengoa in 2017 recorded in Other financial income, as well as to the Impairment of preferred equity investment in ACBH recorded in 2016.

In accordance with the agreement reached with Abengoa with respect to the ACBH investment, Abengoa acknowledged that we are the legal owner of the dividends we retained from Abengoa. As a result, we recorded $10.4 million in our financial statements in 2017 and $28.0 million in 2016, in accordance with the accounting treatment given previously to the ACBH dividend. In addition, upon completion of Abengoa’s restructuring in March 2017, we received restructured debt and equity of Abengoa. In exchange, we waived, as agreed, our rights under the ACBH agreements, including our right to further retain dividends payable to Abengoa and we wrote off the accounting value of this instrument. The net impact of the two transactions resulted in a net loss of $5.8 million, recorded in Other financial losses. Additionally, during 2017, we sold a significant portion of the Abengoa debt and equity instruments we received and recognized a gain of $6.5 million in Other financial income. Other financial income includes a $16.2 million gain resulting from our cancelation of the Abengoa Currency Swap Agreement in 2017.

Other financial losses also include guarantees and letters of credit, wire transfers and other bank fees and other minor financial expenses.

Share of profit of associates carried under the equity method

Share of profit of associates carried under the equity method decreased to $5.3 million for the year ended December 31, 2017, compared with $6.7 million for the year ended December 31, 2016. The decrease is mainly due lower profits in Honaine.

Profit/(loss) before income tax

As a result of the previously mentioned factors, we reported a profit before income taxes of $14.9 million for the year ended December 31, 2017, compared with a profit before income taxes of $3.4 million for the year ended December 31, 2016.

Income tax

Income tax expense amounted to $119.8 million for the year ended December 31, 2017, compared with an income tax expense of $1.7 million for the year ended December 31, 2016. The increase is mainly due to the change of ownership under Section 382 of the Internal Revenue Code, which caused a one-time income tax expense of $96 million and to the U.S. Tax Reform which caused a one-time income tax expense of $19.0 million. See “—Factors Affecting the Comparability of Our Results of Operations” above. As a result, our effective tax rate differed from our nominal tax rate in 2017.

In 2016, our effective tax rate differed from the average nominal tax rate mainly due to a net of different effects. Permanent differences in some jurisdictions, particularly in Mexico had a positive impact in our income tax expense. This effect was offset by tax losses for which we did not record a tax credit in some jurisdictions, in accordance with IFRS.

Further Adjusted EBITDA is calculated as profit/(loss) for the year attributable to the parent company, after adding back loss/(profit) attributable to non-controlling interest from continued operations, income tax, share of profit/(loss) of associates carried under the equity method, finance expense net, depreciation, amortization and impairment charges of entities included in the Annual Consolidated Financial Statements, and dividends received from our preferred equity investment in ACBH. Further Adjusted EBITDA for the first quarter of 2017 includes compensation received from Abengoa in lieu of ACBH dividends. Further Adjusted EBITDA is not a measure of performance under IFRS as issued by the IASB, and you should not consider Further Adjusted EBITDA as an alternative to operating income or profits or as a measure of our operating performance, cash flows from operating, investing and financing activities or as a measure of our ability to meet our cash needs or any other measures of performance under generally accepted accounting principles. We believe that Further Adjusted EBITDA is a useful indicator of our ability to incur and service our indebtedness and can assist securities analysts, investors and other parties to evaluate us. Further Adjusted EBITDA and similar measures are used by different companies for different purposes and are often calculated in ways that reflect the circumstances of those companies. Further Adjusted EBITDA may not be indicative of our historical operating results, nor is it meant to be predictive of potential future results.

North America

Revenue increased by 7.4% to $357.2 million for the year ended December 31, 2018, compared to $332.7 million for the year ended December 31, 2017. The increase was primarily due to higher revenues generated by our solar assets in California and Arizona which had an above average year in terms of production. Additionally, revenue increased in ACT in the portion of the tariff related to the operation and maintenance services, driven by the higher operation and maintenance costs for the year ended December 31, 2018. Further Adjusted EBITDA increased by 9.4% to 308.8 million for the year ended December 31, 2018, compared to $282.3 million for the year ended December 31, 2017. Further Adjusted EBITDA margin increased to 86.4% for the year ended December 31, 2018 compared to 84.9% in the same period in the previous year mainly due to certain one-off items recorded in Solana (see “—Results of Operations—Other operating income” above) and to the positive performance of our U.S. solar assets.

South America

Revenue increased by 2.0% to $123.2 million for the year ended December 31, 2018, compared to $120.8 million for the year ended December 31, 2017, with production and availabilities in line with the same period of last year. Further Adjusted EBITDA decreased by 7.9% to $100.2 million for the year ended December 31, 2018, compared to $108.8 million for the year ended December 31, 2017. Further Adjusted EBITDA margin decreased to 81.3% for the year ended December 31, 2018 compared to 90.0% for the year ended December 31, 2017. Pursuant to the agreement reached with Abengoa in the third quarter of 2016, we were acknowledged as the legal owner of the dividends retained from Abengoa prior to the ACBH agreement settlement. As a result, we recorded $10.4 million income in the first quarter of 2017 in our financial statements, in accordance with the accounting treatment given previously to the ACBH dividend. We no longer own any shares in ACBH and will not retain any additional dividends.

EMEA

Revenue increased by 1.5% to $563.4 million for the year ended December 31, 2018, compared to $554.9 million for the year ended December 31, 2017. The increase was mainly due to higher production levels at Kaxu, our solar plant in South Africa which experienced technical problems during 2017 and performed significantly better in 2018 following the repairs completed during 2017. Revenue also increased due to a more favorable foreign exchange rate between the U.S. dollar and euro. On a constant currency basis, revenue for the year ended December 31, 2018 would have been $544.0 million, representing a decrease of 2.0% compared to the same period of 2017. Further Adjusted EBITDA increased by 13.6% to $441.6 million for the year ended December 31, 2018, compared to $388.2 million for the year ended December 31, 2017. Further Adjusted EBITDA margin increased to 78.4% for the year ended December 31, 2018, compared to 70.0% for the same period in 2017. The increase was mainly attributable to the one-time $39.0 million gain we recognized related to the long-term operation and maintenance payables accrued in Spain (see “—Results of Operations—Other operating income” above).

Further Adjusted EBITDA is calculated as profit/(loss) for the year attributable to the parent company, after adding back loss/(profit) attributable to non-controlling interest from continued operations, income tax, share of profit/(loss) of associates carried under the equity method, finance expense net, depreciation, amortization and impairment charges of entities included in the Annual Consolidated Financial Statements, and dividends received from our preferred equity investment in ACBH. Further Adjusted EBITDA for the first quarter of 2017 includes compensation received from Abengoa in lieu of ACBH dividends. Further Adjusted EBITDA is not a measure of performance under IFRS as issued by the IASB, and you should not consider Further Adjusted EBITDA as an alternative to operating income or profits or as a measure of our operating performance, cash flows from operating, investing and financing activities or as a measure of our ability to meet our cash needs or any other measures of performance under generally accepted accounting principles. We believe that Further Adjusted EBITDA is a useful indicator of our ability to incur and service our indebtedness and can assist securities analysts, investors and other parties to evaluate us. Further Adjusted EBITDA and similar measures are used by different companies for different purposes and are often calculated in ways that reflect the circumstances of those companies. Further Adjusted EBITDA may not be indicative of our historical operating results, nor is it meant to be predictive of potential future results.

Renewable energy

Revenue increased by 3.4% to $793.5 million for the year ended December 31, 2018, compared to $767.2 million for the year ended December 31, 2017. The increase was due in part to a more favorable foreign exchange rate between the U.S. dollar and the euro and the South African Rand. On a constant currency basis, revenue for the year ended December 31, 2018 would have been $773.2 million, representing an increase of 0.8% compared to the same period in 2017. The increase was also due to the higher production in Kaxu and in our U.S. solar assets. Further Adjusted EBITDA increased by 16.7% to $664.4 million for the year ended December 31, 2018, compared to $569.2 million for the year ended December 31, 2017. Further Adjusted EBITDA margin increased to 83.7% for the year ended December 31, 2018 compared to 74.2% for the year ended December 31, 2017 principally due to the one-off $39.0 million gain on the long-term operation and maintenance agreement (see “—Results of Operations—Other operating income” above).

Efficient natural gas

Revenue increased by 9.2% to $130.8 million for the year ended December 31, 2018, compared to $119.8 million for the year ended December 31, 2017. The increase was due in part to the higher revenues in the portion of the tariff related to the operation and maintenance services, driven by the higher operation and maintenance costs in 2018. Operation and maintenance costs are typically higher in the quarters prior to a major maintenance, which is scheduled to take place at the beginning of 2019. As a result, Further Adjusted EBITDA margin decreased from 88.6% in the year ended December 31, 2017, compared to 71.8% in the year ended December 31, 2018. Further Adjusted EBITDA decreased by 11.6% to $93.9 million for the year ended December 31, 2018, compared to $106.1 million for the year ended December 31, 2017.

Electric transmission lines

Revenue remained stable at $96.0 million for year ended December 31, 2018, compared with $95.1 million for the year ended December 31, 2017. Further Adjusted EBITDA decreased to $78.4 million in the year ended December 31, 2018 from $87.7 million in the year ended December 31, 2017, primarily due to the ACBH dividend recorded in the first quarter of 2017. Pursuant to the agreement reached with Abengoa in the third quarter of 2016, we were acknowledged as the legal owner of the dividends retained from Abengoa prior to the ACBH agreement settlement. As a result, we recorded $10.4 million income in the first quarter of 2017 in our financial statements, in accordance with the accounting treatment given previously to the ACBH dividend. We no longer own any shares in ACBH and will not retain any additional dividends. Further Adjusted EBITDA margin decreased from 92.2% in the year ended December 31, 2017, compared to 81.7% in the year ended December 31, 2018.

Water

Revenue and Further Adjusted EBITDA for the year ended December 31, 2018 decreased to $23.5 million and $13.9 million from $26.3 million and $16.3 million, respectively, for the year ended December 31, 2017. This decreased was mainly due to one-off gains recorded in 2017. Further Adjusted EBITDA margin decreased from 62.0% in the year ended December 31, 2017, compared to 59.1% in the year ended December 31, 2018.

North America

Revenues decreased slightly by 1.3% to $332.7 million for the year ended December 31, 2017 compared with $337.0 million for the year ended December 31, 2016. The decrease was primarily due to lower revenues at ACT. Although ACT continued to deliver robust levels of production and availability, revenues in ACT decreased due to lower revenues in the portion of the tariff related to the operation and maintenance services, driven by lower operation and maintenance costs for the year ended December 31, 2017. Further Adjusted EBITDA margin remained stable around 85% for the year 2017 compared to 2016.

South America

Revenues increased slightly by 1.7% to $120.8 million for the year ended December 31, 2017, compared with $118.8 million for the year ended December 31, 2016 mainly due to higher production in our wind assets in Uruguay. Further Adjusted EBITDA decreased to $108.8 million for the year ended December 31, 2017, compared with $124.6 million for the year ended December 31, 2016. According to the agreement reached with Abengoa in the third quarter of 2016, Abengoa acknowledged that we are the legal owner of the dividends retained from Abengoa. As a result, we recorded $28.0 million for the year ended December 31, 2016 and $10.4 million for the year ended December 31, 2017 in accordance with the accounting treatment given previously to the ACBH dividend. Further Adjusted EBITDA margin decreased to 90.0% for the year ended December 31, 2017 from 104.9% for the year ended December 31, 2016 also due to the accounting treatment previously given to the ACBH dividend.

EMEA

Revenues increased by 7.5% to $554.9 million for the year ended December 31, 2017, compared with $516.0 million for the year ended December 31, 2016. The increase was mainly due to higher revenue per MWh produced and higher production of our solar assets in Spain, driven by higher solar radiation levels. The appreciation of the euro against the U.S. dollar for the year ended December 31, 2017 compared to the year ended December 31, 2016 also contributed part of the increase. This was partially offset by reduced performance of Kaxu, our solar asset in South Africa, after the plant experienced technical problems. The repairs were completed in the fourth quarter of 2017 and insurance payments claimed for repairs of water pumps were collected in the second quarter of 2017. As a result, Further Adjusted EBITDA increased to $388.2 million for the year ended December 31, 2017, compared with $354.0 million for the year ended December 31, 2016.

Renewable energy

Revenue increased by 5.9% to $767.2 million for the year ended December 31, 2017, compared with $724.3 million for the year ended December 31, 2016. The increase was mainly due to higher revenue per MWh produced and higher production of our solar assets in Spain. The appreciation of the euro against the U.S. dollar for the year ended December 31, 2017 compared to the year ended December 31, 2016 also contributed part of the increase. As a result of this effect and of the good performance of our Spanish solar assets, Further Adjusted EBITDA increased to $569.2 million for the year ended December 31, 2017, which represented an increase of $30.8 million with respect to the year ended December 31, 2016. Further Adjusted EBITDA margin remained stable for the years ended December 31, 2017 and 2016.

Efficient natural gas

Revenue decreased by 6.5% to $119.8 million for the year ended December 31, 2017, compared with $128.1 million for the year ended December 31, 2016 ACT continued to deliver robust levels of production and availability, however revenues decreased due to the lower revenues in the portion of the tariff related to the operation and maintenance services, driven by lower operation and maintenance costs for the year ended December 31, 2016. Operation and maintenance costs were lower for the year ended December 31, 2017, since operation and maintenance costs are typically higher in the months prior to a major maintenance, which took place in the first quarter of 2016. As a result, Further Adjusted EBITDA margin increased to 88.6% for the year ended December 31, 2017, from 83.2% for the year ended December 31, 2016.

Electric transmission lines

Revenue remained stable at $95.1 million for the year ended December 31, 2017 and 2016. Further Adjusted EBITDA decreased by 16.3% mainly due to difference in the amount of the ACBH dividend recognized in for the year ended December 31, 2016 as compared to the year ended December 31, 2017. In the agreement reached with Abengoa in the third quarter of 2016, Abengoa acknowledged that we are the legal owner of the dividends retained from Abengoa prior to Abengoa’s restructuring. As a result, we recorded $28.0 million for the year ended December 31, 2016 and $10.4 million for the year ended December 31, 2017, in accordance with the accounting treatment given previously to the ACBH dividend.

Water

Revenue amounted to $26.3 million for the year ended December 31, 2017 and Further Adjusted EBITDA amounted to $16.3 million for the year ended December 31, 2017, resulting in 56% Adjusted EBITDA margin.

B.	Liquidity and Capital Resources

The liquidity and capital resources discussion which follows contains certain estimates as of the date of this annual report of our sources and uses of liquidity (including estimated future capital resources and capital expenditures) and future financial and operating results. These estimates, while presented with numerical specificity, necessarily reflect numerous estimates and assumptions made by us with respect to industry performance, general business, economic, regulatory, market and financial conditions and other future events, as well as matters specific to our businesses, all of which are difficult or impossible to predict and many of which are beyond our control. These estimates reflect subjective judgment in many respects and thus are susceptible to multiple interpretations and periodic revisions based on actual experience and business, economic, regulatory, financial and other developments. As such, these estimates constitute forward-looking information and are subject to risks and uncertainties that could cause our actual sources and uses of liquidity (including estimated future capital resources and capital expenditures) and financial and operating results to differ materially from the estimates made here, including, but not limited to, our performance, industry performance, general business and economic conditions, customer requirements, competition, adverse changes in applicable laws, regulations or rules, and the various risks set forth in this annual report. See “Forward-looking Statements.”

In addition, these estimates reflect assumptions of our management as of the time that they were prepared as to certain business decisions that were and are subject to change. These estimates also may be affected by our ability to achieve strategic goals, objectives and targets over the applicable periods. The estimates cannot, therefore, be considered a guarantee of future sources and uses of liquidity (including estimated future capital resources and capital expenditures) and future financial and operating results, and the information should not be relied on as such. None of us, or our board of directors, advisors, officers, directors or representatives intends to, and each of them disclaims any obligation to, update, revise, or correct these estimates, except as otherwise required by law, including if the estimates are or become inaccurate (even in the short-term).

The inclusion of these estimates in this annual report should not be deemed an admission or representation by us or our board of directors that such information is viewed by us or our board of directors as material information of ours. Such information should be evaluated, if at all, in conjunction with the historical financial statements and other information about us contained in this annual report. None of us, or our board of directors, advisors, officers, directors or representatives has made or makes any representation to any prospective investor or other person regarding our ultimate performance compared to the information contained in these estimates or that forecasted results will be achieved. In light of the foregoing factors and the uncertainties inherent in the information provided above, investors are cautioned not to place undue reliance on these estimates. Our liquidity plans are subject to a number of risks and uncertainties, some of which are outside of our control. Macroeconomic conditions could limit our ability to successfully execute our business plans and, therefore, adversely affect our liquidity plans. See “Item 3.D — Risk Factors.”

Our principal liquidity and capital requirements consist of the following:

·	debt service requirements on our existing and future debt;

·	cash dividends to investors; and

·	acquisitions of new companies and operations (see “Item 4.B — Business Overview—Our Business Strategy”).

As a normal part of our business, depending on market conditions, we will from time to time consider opportunities to repay, redeem, repurchase or refinance our indebtedness. Changes in our operating plans, lower than anticipated sales, increased expenses, acquisitions or other events may cause us to seek additional debt or equity financing in future periods. There can be no guarantee that financing will be available on acceptable terms or at all. Debt financing, if available, could impose additional cash payment obligations and additional covenants and operating restrictions. In addition, any of the items discussed in detail under “Item 3.D — Risk Factors” and other factors may also significantly impact our liquidity.

Table of Contents

Liquidity position

As of December 31, 2018, our cash and cash equivalents at the project company level were $524.8 million compared to $520.9 million as of December 31, 2017. In addition, our cash and cash equivalents at the Atlantica Yield plc level were $106.7 million as of December 31, 2018 compared to $148.5 million as of December 31, 2017. Additionally, as of December 31, 2018, we had approximately $105 million available under our Revolving Credit Facility and therefore a total corporate liquidity of $211.7 million. On January 25, 2019, we entered into an amendment to our Revolving Credit Facility under which the total amount was increased from $215 million to $300 million. Considering this increase, availability under our Revolving Credit Facility would have been $190 million and therefore our total corporate liquidity would have been $296.7 million. As of December 31, 2017, we had $71.0 million available under our Former Revolving Credit Facility and our total corporate liquidity was $219.5 million.

Sources of liquidity

We expect our ongoing sources of liquidity to include cash on hand, cash generated from our operations, project debt arrangements, corporate debt and the issuance of additional equity securities, as appropriate, and given market conditions. Our financing agreements consist mainly of the project-level financings for our various assets, the 2019 Notes, the Revolving Credit Facility, the Note Issuance Facility and a line of credit with a local bank.

On November 17, 2014, we issued the 2019 Notes in an aggregate principal amount of $255 million. The 2019 Notes accrue annual interest of 7.000% payable semi-annually beginning on May 15, 2015 until their maturity date of November 15, 2019. As required by the Indenture governing the 2019 Notes, we have obtained a public credit rating for the 2019 Notes from S&P and Moody’s.

On February 10, 2017, we signed a Note Issuance Facility, a senior secured note facility with a group of funds managed by Westbourne Capital as purchasers of the notes issued thereunder for a total amount of €275 million (approximately $315.7 million), with three series of notes: series 1 notes worth €92 million mature in 2022; series 2 notes worth €91.5 million mature in 2023; and series 3 notes worth €91.5 million mature in 2024. Interest on all three series accrues at a rate per annum equal to the sum of 3-month EURIBOR plus 4.90%. The proceeds of the Note Issuance Facility were used to repay and subsequently cancel the tranche B under our Former Revolving Credit Facility. We fully hedged the Note Issuance Facility with a swap that fixed the interest rate at 5.5%.

In July 2017, we signed a line of credit with a bank for up to €10.0 million (approximately $11.5 million) which is available in euros or U.S. dollars. Amounts drawn accrue interest at a rate per annum equal to EURIBOR plus 2.25% or LIBOR plus 2.25%, depending on the currency. The credit facility has a maturity date of July 20, 2019 and was fully drawn as of December 31, 2018.

On May 10, 2018, we entered into a $215 million Revolving Credit Facility with a syndicate of banks that matures in December 2021. The facility was increased by $85 million to $300 million in January 2019. The loans under the facility accrue interest at a rate per annum equal to: (A) for Eurodollar rate loans, LIBOR plus a percentage determined by reference to our leverage ratio, ranging between 1.60% and 2.25% and (B) for base rate loans, the highest of (i) the rate per annum equal to the weighted average of the rates on overnight U.S. Federal funds transactions with members of the U.S. Federal Reserve System arranged by U.S. Federal funds brokers on such day plus 1/2 of 1.00%, (ii) the prime rate of the administrative agent under the Revolving Credit Facility and (iii) LIBOR plus 1.00%, in any case, plus a percentage determined by reference to our leverage ratio, ranging between 0.60% and 1.00%. As of December 31, 2018, we had approximately $110.0 million outstanding under the Revolving Credit Facility. On January 25, 2019, we entered into an amendment to our Revolving Credit Facility under which the total amount was increased from $215 million to $300 million. Considering this increase, availability under our Revolving Credit Facility would have been $190 million and therefore our total corporate liquidity would have been $296.7 million. The Revolving Credit Facility replaced tranche A of the Former Revolving Credit Facility, which was repaid and cancelled ahead of its maturity.

Our ability to meet our debt service obligations and other capital requirements, including capital expenditures, as well as acquisitions, will depend on our future operating performance which, in turn, will be subject to general economic, financial, business, competitive, legislative, regulatory and other conditions, many of which are beyond our control.

Table of Contents

We believe that our existing liquidity position and cash flows from operations will be sufficient to meet our requirements and commitments for the next 12 months and to distribute dividends to our investors. Based on our current level of operations, we believe our cash flow from operations and available cash will be adequate to meet our future liquidity needs for at least the next twelve months. Please see “Item 3.D — Risk Factors—Risks Related to Our Indebtedness—Potential future defaults by our subsidiaries, Abengoa or other persons could adversely affect us.”

Cash dividends to investors

We intend to distribute to holders of our shares a significant portion of our cash available for distribution less all cash expense including corporate debt service and corporate general and administrative expenses and less reserves for the prudent conduct of our business (including, among other things, dividend shortfall as a result of fluctuations in our cash flows), on an annual basis. We intend to distribute a quarterly dividend to shareholders. Our board of directors may, by resolution, amend the cash dividend policy at any time. The determination of the amount of the cash dividends to be paid to holders of our shares will be made by our board of directors and will depend upon our financial condition, results of operations, cash flow, long-term prospects and any other matters that our board of directors deem relevant.

Table of Contents

Our cash available for distribution is likely to fluctuate from quarter to quarter and, in some cases, significantly as a result of the seasonality of our assets, the terms of our financing arrangements, maintenance and outage schedules, among other factors. Accordingly, during quarters in which our projects generate cash available for distribution in excess of the amount necessary for us to pay our stated quarterly dividend, we may reserve a portion of the excess to fund cash distributions in future quarters. In quarters in which we do not generate sufficient cash available for distribution to fund our stated quarterly cash dividend, if our board of directors so determines, we may use retained cash flow from other quarters, as well as other sources of cash.

On February 27, 2018, our board of directors approved a dividend of $0.31 per share. The dividend was paid on March 27, 2018, to shareholders of record as of March 19, 2018.

On May 11, 2018, our board of directors approved a dividend of $0.32 per share. The dividend was paid on June 15, 2018 to shareholders of record as of May 31, 2018.

On July 31, 2018, our board of directors approved a dividend of $0.34 per share. The dividend was paid on September 15, 2018, to shareholders of record as of August 31, 2018.

On October 31, 2018, our board of directors approved a dividend of $0.36 per. The dividend was paid on December 14, 2018, to shareholders of record as of November 30, 2018.

Net cash flows provided by/(used in) operating activities

Net cash provided by operating activities in the year ended December 31, 2018 was $401.0 million compared to $385.6 million for the year ended December 31, 2017. The increase resulted from a higher profit for the period adjusted by financial expense and non-monetary items, mainly due to an increase in Further Adjusted EBITDA, particularly in EMEA and North America. This increase was partially offset by variations in working capital, which had a negative impact of $18.3 million in the year ended December 31, 2018 compared to a negative impact of $8.8 million in the year 2017. The increase in negative variations in working capital was mainly caused by higher payments of operation and maintenance variable fees in Spain in 2017, which resulted from increased production levels in these assets in 2017, since a portion of the operation and maintenance cost is a variable cost based on production which is payable the following year. Net interest paid decreased slightly in the year ended December 31, 2018 when compared to the previous year, in accordance with the progressive reduction in project debt.

For the year ended December 31, 2017, net cash provided by operating activities increased by 15.3% to $385.6 million compared with $334.4 million for the year ended December 31, 2016. Profit adjusted by financial expenses and other non-monetary items increased by 11.6% to $743.9 million compared with $666.4 million for the year ended December 31, 2016. Adjustments to reconcile after-tax profit to net cash generated by operating activities correspond mainly to depreciation, amortization and impairment expense and finance expenses partially offset by other non-monetary items, consisting mainly of income related to grants provided by the U.S. Treasury to Solana and Mojave. The $77.5 million increase in profit adjusted by financial expenses and other non-monetary items was mainly due to higher Further Adjusted EBITDA in 2017 in our Spanish solar assets due to higher remuneration and production. Variations in working capital in 2017 remained low compared to the previous year, since our working capital is generally stable on a yearly basis, with variations during the year due to seasonality. Net interest and taxes paid increased by 4.6% to $349.5 million for the year ended December 31, 2017 compared with $334.0 million for the year ended December 31, 2016, mainly due to slightly higher interest rate of our corporate debt after we refinanced the short-term tranche B of our Former Revolving Credit Facility with the Note Issuance Facility agreement.

Net cash provided by/(used in) investing activities

For the year ended December 31, 2018, net cash used in investing activities was $14.9 million and included $73.2 million of acquisitions previously announced, corresponding to the acquisition of Melowind ($42.8 million), the first payment related to the expansion of our ATN transmission line ($14.2 million), the acquisition of a mini-hydroelectric plant in Peru ($9.3 million) and the acquisition of Chile TL3 ($6.0 million). Net cash used in investing activities also included $67.9 million related to the $136.5 million received by Solana from Abengoa in relation to the DOE consents to decrease Abengoa’s ownership in Atlantica to 16.5% and to allow Abengoa to sell entirely its stake in Atlantica. From an accounting perspective, since the payment resulted from Abengoa’s obligations under the EPC contract, most of the amount received in 2018 was recorded as reducing the asset value and was therefore classified as cash provided by investing activities

For the year ended December 31, 2017, net cash provided by investing activities was $71.4 million, due primarily to $30.1 million of net proceeds received from the sale of the financial instruments received from Abengoa as part of the agreement related to the ACBH, and $42.5 million received by Solana from Abengoa as a result of obligations as EPC contractor and pursuant to the consent signed with the DOE. Since the payment results from Abengoa’s obligations under the construction contract, from an accounting perspective the payment is considered as lower consideration paid for the asset, reducing the asset value, and is classified as cash provided by investing activities. See “—Factors Affecting the Comparability of Our Results of Operations—Results of Operations” above.

For the year ended December 31, 2016, net cash used in investing activities was $26.3 million due primarily to the payments totaling $21.8 million for the pending payment of Solaben 1/6 and the acquisition of Seville PV.

Net cash provided by/(used in) financing activities

For the year ended December 31, 2018, Net cash used in financing activities was $405.2 million and corresponded principally to $386.0 million of the repayments of principal of our financing agreements, of which $61.6 million were prepayments by Solana using the proceeds of the two payments received from Abengoa in connection with the DOE consents and $54 million corresponded to the prepayment and cancelation of our Former Revolving Credit Facility. The remainder corresponded mostly to scheduled project debt repayments. Additionally, we drew down $107.5 million of the new Revolving Credit Facility which was signed in May 2018 and we paid $143.0 million of dividends to shareholders and non-controlling interest.

Net cash used in financing activities for the year ended December 31, 2017 was $416.3 million due primarily to $252.2 million of scheduled repayments of principal of our project financing agreements, $99.5 million of dividends paid to shareholders and non-controlling interest, $290.0 million of prepayment of tranche B of the Former Revolving Credit Facility during the first quarter of 2017 and $71.0 million of partial prepayment of tranche A of the Former Revolving Credit Facility during the third and fourth quarters of 2017. These cash outflows were offset mainly by $284.7 million of financing proceeds received under the Note Issuance Facility signed in the first quarter of 2017 and $11.7 million of financing proceeds received under a line of credit with a bank signed in the third quarter of 2017.

Net cash used in financing activities for the year ended December 31, 2016 was $226.1 million primarily due to the $182.6 million of principal debt repayment made by the assets, $35.5 million of dividends paid to shareholders and non-controlling interest and $19.7 million payment for acquisition of the 13% stake in Solacor 1/2 from the minority partner in the project (JGC), partially offset by $14.9 million of the proceeds of the refinancing in ATN2.

Financing Arrangements

2019 Notes

On November 17, 2014, we issued the 2019 Notes in an aggregate principal amount of $255 million. Interest accrues on the 2019 Notes from November 17, 2014 until November 15, 2019, the maturity date, at a rate of 7.000% per annum. The 2019 Notes were offered and issued in transactions exempt from registration to certain qualified institutional buyers in the United States, under Rule 144A under the Securities Act, and to institutional investors outside the United States, under Regulation S under the Securities Act.

The proceeds from the offering of the 2019 Notes were used, together with a portion of the proceeds of the Revolving Credit Facility, to finance the acquisition of the First Dropdown Assets from Abengoa pursuant to the Abengoa ROFO Agreement. See “Item 4.B—Business Overview—Our Growth Strategy—First Dropdown Assets.” The total aggregate consideration for the First Dropdown Assets was $312 million (which consideration was determined in part by converting the portion of the purchase price of Solacor 1/2 and PS10/20 denominated in euros into U.S. dollars based on the exchange rate on the date on which the payment was made).

As of the date of this annual report, $255 million aggregate principal amount of the 2019 Notes remain outstanding. The 2019 Notes are guaranteed on a senior unsecured basis by our subsidiaries ASHUSA Inc., ASUSHI Inc., ABY South Africa (Pty) LTD, ABY Concessions Peru, S.A., ABY Concessions Infrastructures S.L.U. and ACT Holding, S.A. de C.V. If we fail to make payments on the 2019 Notes as required under the Indenture governing such notes, the guarantors are obligated to make such payments.

The Indenture governing the 2019 Notes provides, among other things, that the 2019 Notes and the guarantees are our and the guarantors’, respectively, general unsecured obligations and rank equally (subject to any applicable statutory exemptions) in right of payment with all of our and the guarantors’, respectively, existing and future debt that is not subordinated in right of payment and be effectively subordinated to all of our and the guarantors’, respectively, existing and future secured debt to the extent of the assets securing such debt and to any preferential obligations under applicable law. Interest is payable on the 2019 Notes on May 15 and November 15 of each year beginning on May 15, 2015 until their maturity date of November 15, 2019.

157

Table of Contents

The Indenture governing the 2019 Notes contains covenants that limit certain of our and the guarantors’ activities, including those relating to: incurring additional indebtedness; paying dividends on, redeeming or repurchasing our capital stock; prepaying subordinated indebtedness; making certain investments; imposing certain restrictions on the ability of subsidiaries to pay dividends or other payments; creating certain liens; transferring or selling assets; merging or consolidating with other entities; entering into transactions with affiliates; and engaging in unrelated businesses. Each of the covenants is subject to a number of important exceptions and qualifications. The Indenture governing the 2019 Notes also contains customary events of default (subject in certain cases to customary grace and cure periods). Generally, if an event of default occurs and is not cured within the time periods specified, the trustee or the holders of at least 25% in principal amount of the 2019 Notes then outstanding may declare all of the 2019 Notes to be due and payable immediately.

Revolving Credit Facility

On May 10, 2018, we entered into a $215 million revolving credit facility with a syndicate of banks (the “Revolving Credit Facility”) which matures in December 2021. The Revolving Credit Facility was increased by $85 million to $300 million on January 25, 2019. As of December 31, 2018, we had $110 million outstanding under the Revolving Credit Facility. Thus, as of December 31, 2018, we had approximately $105 million available under Revolving Credit Facility. Assuming the increase had taken place on December 31, 2018, we would have had $190 million available. The Revolving Credit Facility replaced tranche A of the Former Revolving Credit Facility, which was repaid and cancelled ahead of its maturity.

Loans under the Revolving Credit Facility accrue interest at a rate per annum equal to: (A) for Eurodollar rate loans, LIBOR plus a percentage determined by reference to our leverage ratio, ranging between 1.60% and 2.25% and (B) for base rate loans, the highest of (i) the rate per annum equal to the weighted average of the rates on overnight U.S. Federal funds transactions with members of the U.S. Federal Reserve System arranged by U.S. Federal funds brokers on such day plus 1/2 of 1.00%, (ii) the prime rate of the administrative agent under the Revolving Credit Facility and (iii) LIBOR plus 1.00%, in any case, plus a percentage determined by reference to our leverage ratio, ranging between 0.60% and 1.00%. Letters of credit are subject to a sublimit under the Revolving Credit Facility of $70 million.

Our payment obligations under the Revolving Credit Facility are guaranteed by our subsidiaries ABY Concessions Infrastructures, S.L.U., ABY Concessions Perú S.A., ACT Holding, S.A. de C.V., ASHUSA Inc., ASUSHI Inc. and Atlantica Yield South Africa Ltd. The Revolving Credit Facility is also secured by a high percentage of our assets and the assets of the guarantors, subject to customary exceptions.

The Revolving Credit Facility contains covenants that limit certain of our and the guarantors’ activities, including those relating to: mergers; customary change of control provisions; consolidations; the ability to incur additional indebtedness; sales, transfers and other dispositions of property and assets; providing new guarantees; investments; granting additional security interests, transactions with affiliates and our ability to pay cash dividends and is also subject to certain standard restrictions. Additionally, we are required to comply with (i) a maintenance leverage ratio of our indebtedness at the holding level to our cash available for distribution of 5.0x and (ii) debt service coverage ratio of cash available for distribution to debt service payments of 2.0x. The Revolving Credit Facility also contains customary events of default, upon the occurrence of which the lenders holding more than 50% of the aggregate loans and commitments then outstanding have the ability to declare the unpaid principal amount of all outstanding loans, and interest accrued thereon, to be immediately due and payable. In addition, the Revolving Credit Facility includes a material non-recourse subsidiary default provision related to a default by our project subsidiaries in their financing arrangements, such that a payment default by one or more of our non-recourse subsidiaries representing more than 25% of the cash available for distribution distributed in the previous four fiscal quarters could trigger a default under our Revolving Credit Facility.

Note Issuance Facility

On February 10, 2017, we entered into a senior secured note facility with Elavon Financial Services DAC, UK Branch as agent and a group of funds managed by Westbourne Capital as purchasers of the notes issued thereunder for a total amount of €275 million (approximately $330 million), or the Note Issuance Facility, with three series of notes: series 1 notes worth €92 million mature in 2022; series 2 notes worth €91.5 million mature in 2023; and series 3 notes worth €91.5 million mature in 2024. Interest on all three series accrues at a rate per annum equal to the sum of three-month EURIBOR plus 4.90%. We fully hedged the Note Issuance Facility with a swap that fixed the interest rate at 5.5% immediately following the funding.

158

Table of Contents

The obligations under the Note Issuance Facility rank pari passu with our outstanding obligations under tranche A of the Revolving Credit Facility as well as the 2019 Notes. Our payment obligations under the Note Issuance Facility are guaranteed, collectively, by ASHUSA Inc., ASUSHI Inc., Atlantica Yield South Africa Ltd, ABY Concessions Perú S.A., ABY Concessions Infrastructures, S.L.U. and ACT Holding, S.A. de C.V. The Note Issuance Facility is also secured by a high percentage of our assets and the assets of the guarantors, subject to customary exceptions.

The Note Issuance Facility contains covenants that limit certain of our and the guarantors’ activities, including those relating to: mergers; consolidations; certain limitations on the ability to incur additional indebtedness; sales, transfers and other dispositions of property and assets; providing new guarantees; investments; granting additional security interests, transactions with affiliates and our ability to pay cash dividends is also subject to certain standard restrictions. Additionally, we are required to comply with (i) a maintenance leverage ratio of our indebtedness (including that of our subsidiaries) to our cash available for distribution of 5.00:1.00 on and after January 1, 2017, and of 4.75:1.00 on and after January 1, 2020, and (ii) a debt service coverage ratio of 2.00:1.00 of cash available for distribution to debt service payments.

The Note Issuance Facility also contains customary events of default, upon the occurrence of which holders of more than 50% of the notes outstanding have the ability of the lenders to declare the unpaid principal amount of all outstanding notes, and interest accrued thereon, to be immediately due and payable. In addition, our Note Issuance Facility includes a material subsidiary cross-default provision such that a payment default by one or more of our non-recourse subsidiaries representing more than 20% of the cash available for distribution distributed in the previous four fiscal quarters could trigger a default, provided that these subsidiaries have an indebtedness higher than $100 million in the case of non-recourse subsidiaries or more than $75 million in the case of subsidiaries other than non-recourse subsidiaries.

The proceeds of the Note Issuance Facility were used for the repayment and cancellation of tranche B under the Former Revolving Credit Facility.

Other Credit Lines

In July 2017, we signed a line of credit with a bank for up to €10.0 million (approximately $11.5 million) which is available in euros or U.S. dollars. Amounts drawn accrue interest at a rate per annum equal to EURIBOR plus 2.25% or LIBOR plus 2.25%, depending on the currency. The credit line matures in July 2019 and was fully drawn as of December 31, 2018.

Project level financing

We have outstanding project-specific debt that is backed by certain of our assets. These financing arrangements generally include a pledge of shares of the entities holding our assets and customary covenants, including restrictive covenants that limit the ability of the project-level entities to make cash distributions to their parent companies and ultimately to us including if certain financial ratios are not met. For more information about the debt of project level entities, see “Item 4.B—Business Overview—Our Operations.”

Critical Accounting Policies and Estimates

The preparation of our Annual Consolidated Financial Statements in conformity with IFRS requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. We base our estimates on historical experience and on various other assumptions we believe to be reasonable under the specific circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

159

Table of Contents

An understanding of the accounting policies for these items is important to understand the Annual Consolidated Financial Statements. The following discussion provides more information regarding the estimates and assumptions used for these items in accordance with IFRS and should be considered in conjunction with the Annual Consolidated Financial Statements.

The most critical accounting policies, which reflect significant management estimates and judgment to determine amounts in our Annual Consolidated Financial Statements, are as follows:

Contracted concessional agreements and PPAs;

Impairment of intangible assets and property, plants and equipment;

Assessment of control;

Derivative financial instruments and fair value estimates; and

Income taxes and recoverable amount of deferred tax assets.

Some of these accounting policies require the application of significant judgment by management to select the appropriate assumptions to determine these estimates. These assumptions and estimates are based on our historical experience, forecasts and other circumstances and expectations as of the close of the financial period. The assessment is considered in relation to the global economic situation of the industries and regions where we operate, taking into account future development of our businesses. By their nature, these judgments are subject to an inherent degree of uncertainty; therefore, actual results could materially differ from the estimates and assumptions used. In such cases, the carrying values of assets and liabilities are adjusted.

As of the date of preparation of our Annual Consolidated Financial Statements, no relevant changes in the estimates made are anticipated and, therefore, no significant changes in the value of the assets and liabilities recognized at December 31, 2018, are expected.

Although these estimates and assumptions are being made using all available facts and circumstances, it is possible that future events may require management to amend such estimates and assumptions in future periods. Changes in accounting estimates are recognized prospectively, in accordance with IAS 8, in the consolidated income statement of the year in which the change occurs. Our significant accounting policies are more fully described in note 2 to our Annual Consolidated Financial Statements, presented elsewhere in this annual report.

Contracted concessional agreements

Contracted concessional assets and price purchase agreements (PPAs) include fixed assets financed through project debt, related to service concession arrangements recorded in accordance with IFRIC 12, except for Palmucho, which is recorded in accordance with IAS 17 and PS10, PS20, Mini-Hydro, Chile TL 3 and Seville PV, which are recorded as tangible assets in accordance with IAS 16. The infrastructures accounted for as concessions are related to the activities concerning electric transmission lines, solar electricity generation plants, cogeneration plants, wind farms and water desalination plants. The infrastructure used in a concession can be classified as an intangible asset or a financial asset, depending on the nature of the payment entitlements established in the agreement.

The application of IFRIC 12 requires extensive judgment in relation with, among other factors, (i) the identification of certain infrastructures and contractual agreements in the scope of IFRIC 12, (ii) the understanding of the nature of the payments in order to determine the classification of the infrastructure as a financial asset or as an intangible asset and (iii) the timing and recognition of the revenue from construction and concessionary activity.

Under the terms of contractual arrangements within the scope of this interpretation, the operator shall recognize and measure revenue in accordance with IFRS 15 for the services it performs. If the operator performs more than one service (i.e., construction or upgrade services and operation services) under a single contract or arrangement, consideration received or receivable shall be allocated by reference to the relative fair values of the services delivered, when the amounts are separately identifiable.

Intangible assets

We recognize an intangible asset to the extent that we receive a right to charge final customers for the use of the infrastructure. This intangible asset is subject to the provisions of IAS 38 and is amortized linearly, taking into account the estimated period of commercial operation of infrastructure, which generally coincides with the concession period.

160

Table of Contents

Once the infrastructure is in operation, the treatment of income and expenses is as follows:

Revenues from the updated annual revenue for the contracted concession, as well as operations and maintenance services are recognized in each period according to IFRS 15 “Revenue from contracts with customers”

Operating and maintenance costs and general overheads and administrative costs are recorded in accordance with the nature of the cost incurred (amount due) in each period.

Financing costs are expensed as incurred.

Financial assets

We recognize a financial asset when demand risk is assumed by the grantor, to the extent that the contracted concession holder has an unconditional right to receive payments for the asset. This asset is recognized at the fair value of the construction services provided, considering upgrade services in accordance with IFRS 15, if any.

The financial asset is subsequently recorded at amortized cost calculated according to the effective interest method. Revenue from operations and maintenance services is recognized in each period according to IFRS 15 “Revenue from contracts with Customers.” The remuneration of managing and operating the asset resulting from the valuation at amortized cost is also recorded in revenue.

Financing costs are expensed as incurred.

According to IFRS 9, we recognise an allowance for expected credit losses (ECLs) for all debt instruments not held at fair value through profit or loss. ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that we expect to receive.

There are two main approaches to applying the ECL model according to IFRS 9: the general approach which involves a three stage approach, and the simplified approach, which can be applied to trade receivables, contract assets and lease receivables. We have elected to apply the simplifed approach. Under this approach, there is no need to monitor for significant increases in credit risk and entities will be required to measure lifetime expected credit losses at each end of reporting period.

The key elements of the ECL calculations are the following:

the Probability of Default (“PD”) is an estimate of the likelihood of default over a given time horizon. We calculates PD based on Credit Default Swaps spreads (“CDS”);

the Exposure at Default (“EAD”) is an estimate of the exposure at a future default date;

the Loss Given Default (“LGD”) is an estimate of the loss arising in the case where a default occurs at a given time. It is based on the difference between the contractual cash flows due and those that we would expect to receive. It is expressed as a percentage of the EAD.

Property, plant and equipment

Assets recorded as property, plant and equipment (PS10/20, Mini-Hydro, Chile TL3and Seville PV) are measured at historical cost, including all expenses directly attributable to the acquisition, less depreciation and impairment losses, with the exception of land, which is presented net of any impairment losses. Once the infrastructure is in operation, the treatment of income and expenses is equal to intangible assets.

Impairment of intangible assets and property, plant and equipment

We review our contracted revenue assets to identify any indicators of impairment annually.

161

Table of Contents

The recoverable amount of an asset is the higher of its fair value less costs to sell and its value in use, defined as the present value of the estimated future cash flows to be generated by the asset. In the event that the asset does not generate cash flows independently of other assets, we calculate the recoverable amount of the cash generating unit, or CGU to which the asset belongs.

When the carrying amount of the CGU to which these assets belong is lower than its recoverable amount assets are impaired.

Assumptions used to calculate value in use include a discount rate and projections considering real data based on the contract terms and projected changes in both selling prices and costs. The discount rate is estimated by management, to reflect both changes in the value of money over time and the risks associated with the specific CGU.

For contracted or concession revenue assets with a defined useful life and with a specific financial structure, cash flow projections until the end of the project are considered and no terminal value is assumed. Contracted revenue assets have a contractual structure that permits to estimate quite accurately the costs of the project (both in the construction and in the operations periods) and revenue during the life of the project.

Projections take into account real data based on the contract terms and fundamental assumptions based on part in specific reports prepared internally and supported by specialists, assumptions on demand and assumptions on production. Additionally, assumptions on macroeconomic conditions are also taken into account, such as inflation rates, future interest rates and sensitivity analysis are performed over all major assumptions, which can have a significant impact on the value of the asset.

Cash flow projections of CGUs are calculated in the functional currency of those CGUs and are discounted using rates that take into consideration the risk corresponding to each specific country and currency.

Taking into account that in most CGUs its specific financial structure is linked to the financial structure of the projects that are part of those CGUs, the discount rate used to calculate the present value of cash flow projections is based on the weighted average cost of capital, or WACC, for the type of asset, adjusted, if necessary, in accordance with the business of the specific activity and with the risk associated with the country where the project is performed. In any case, sensitivity analyses are performed, especially in relation with the discount rate used and fair value changes in the main business variables, in order to ensure that possible changes in the estimates of these items do not impact the possible recovery of recognized assets. See note 2 to our Annual Consolidated Financial Statements for further information on WACC.

In the event that the recoverable amount of an asset is lower than its carrying amount, an impairment charge for the difference would be recorded in the consolidated income statement under the item “depreciation, amortization and impairment charges.”

Considering the lower production compared with the run-rate production expected for Solana due to the technical issues experienced since COD in the asset and the uncertainty around level of production in the future, we identified a triggering event of impairment during the year 2018 in compliance with IAS 36, Impairment of Assets. As a result, an impairment test has been performed resulting in the recording of an impairment loss of $42,721 thousand as of December 31, 2018.

The impairment has been recorded within the line “Depreciation, amortization and impairment charges” of the consolidated income statement, decreasing the amount of “Contracted concessional assets” pertaining to the Renewable energy sector and North America geography. The recoverable amount considered is the value in use and amounts to $1,141,209 thousand for Solana, as of December 31, 2018. A specific discount rate has been used in each year considering changes in the debt/equity leverage ratio over the useful life of this project, resulting in the use of a range of discount rates between 5.0% and 5.8%.

An adverse change in the key assumptions which are individually used for the valuation could lead to future impairment recognition; especially, a 5% decrease in generation over the entire remaining useful life of the project would generate an additional impairment of approximately $72 million. An increase of 50 basis points in the discount rate would lead to an additional impairment of approximately $50 million.

In addition, we identified an impairment triggering event for Mojave as a result of the negative credit outlooks for PG&E, the offtaker of the plant, as of December 31, 2018. This project is within the Renewable energy sector and North America geography. We therefore performed an impairment test as of December 31, 2018, which resulted in the recoverable amount (value in use) exceeding the carrying amount of the asset by 10%. To determine the value in use of the asset, a specific discount rate has been used in each year considering changes in the debt/equity leverage ratio over the useful life of this project, resulting in the use of a range of discount rates between 4.6% and 5.8%.

An adverse change in the key assumptions which are individually used for the valuation would not lead to future impairment recognition; neither in case of a 5% decrease in generation over the entire remaining useful life (PPA) of the project nor in case of an increase of 50 basis points in the discount rate.

Assessment of control

Control over an investee is achieved when we have power over the investee, we are exposed, or have rights, to variable returns from our involvement with the investee and have the ability to use its power to affect its returns. We reassess whether or not we control an investee when facts and circumstances indicate that there are changes to one or more of these three elements of control.

We use the acquisition method to account for business combinations of companies controlled by a third party. According to this method, identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. Any contingent consideration is recognized at fair value at the acquisition date and subsequent changes in its fair value are recognized in accordance with IFRS 9 either in profit or loss or as a change to other comprehensive income. Acquisition-related costs are expensed as incurred. We recognize any non-controlling interest in the acquired entity either at fair value or at the non-controlling interest’s proportionate share of the acquirer’s net assets on an acquisition-by-acquisition basis.

All assets and liabilities between entities within the group, equity, income, expenses and cash flows relating to transactions between entities of the group are eliminated in full.

Derivative financial instruments and fair value estimates

Derivatives are recorded at fair value. We apply hedge accounting to all hedging derivatives that qualify to be accounted for as hedges under IFRS.

When hedge accounting is applied, hedging strategy and risk management objectives are documented at inception, as well as the relationship between hedging instruments and hedged items. Effectiveness of the hedging relationship needs to be assessed on an ongoing basis. Effectiveness tests are performed prospectively at inception and at each reporting date, following the dollar offset method.

We apply cash flow hedge accounting. Under this method, the effective portion of changes in fair value of derivatives designated as cash flow hedges are recorded temporarily in equity and are subsequently reclassified from equity to profit or loss in the same period or periods during which the hedged item affects profit or loss. Any ineffective portion of the hedged transaction is recorded in the consolidated income statement as it occurs.

When interest rate options are designated as hedging instruments, the intrinsic value and time value of the financial hedge instrument are separated. Changes in intrinsic and time value which are highly effective are recorded in equity and subsequently reclassified from equity to profit or loss in the same period or periods during which the hedged item affects profit or loss. Any ineffectiveness is recorded as financial income or expense as it occurs.

When the hedging instrument matures or is sold, or when it no longer meets the requirements to apply hedge accounting, accumulated gains and losses recorded in equity remain as such until the forecast transaction is ultimately recognized in the income statement. However, if it becomes unlikely that the forecast transaction will actually take place, the accumulated gains and losses in equity are recognized immediately in the income statement.

Table of Contents

The inputs used to calculate fair value of our derivatives are based on inputs other than quoted prices that are observable for the asset or liability, either directly (i.e., as prices) or indirectly (i.e., derived from prices), through the application of valuation models (Level 2). The valuation techniques used to calculate fair value of our derivatives include discounting estimated future cash flows, using assumptions based on market conditions at the date of valuation or using market prices of similar comparable instruments, amongst others. The valuation of derivatives requires the use of considerable professional judgment. These determinations were based on available market information and appropriate valuation methodologies. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

Income taxes and recoverable amount of deferred tax assets

The current income tax provision is calculated on the basis of relevant tax laws in force at the date of the statement of financial position in the countries in which the subsidiaries and associates operate and generate taxable income.

Determining income tax payable requires judgment in assessing the timing and the amount of deductible and taxable items, as well as the interpretation and application of tax laws in different jurisdictions. Due to this fact, contingencies or additional tax expenses could arise as a result of tax inspections or different interpretations of certain tax laws by the corresponding tax authorities.

We recognize deferred tax assets for all deductible temporary differences and all unused tax losses and tax credits to the extent that it is probable that future taxable profit will be available against which they can be utilized.

We consider it probable that we will have sufficient taxable profit available in the future to enable a deferred tax asset to be recovered when:

There are sufficient taxable temporary differences relating to the same tax authority, and the same taxable entity is expected to reverse either in the same period as the expected reversal of the deductible temporary difference or in periods into which a tax loss arising from the deferred tax asset can be carried back or forward.

It is probable that the taxable entity will have sufficient taxable profit, relating to the same tax authority and the same taxable entity, in the same period as the reversal of the deductible temporary difference (or in the periods into which a tax loss arising from the deferred tax asset can be carried back or forward).

Tax planning opportunities are available to the entity that will create taxable profit in appropriate periods.

Our management assesses the recoverability of deferred tax assets on the basis of estimates of future taxable profit. These estimates are derived from the projections of each of our assets. Based on our current estimates, we expect to generate sufficient future taxable income to achieve the realization of our current tax credits and tax loss carryforwards, supported by our historical trend of business performance.

In assessing the recoverability of our deferred tax assets, our management also considers the foreseen reversal of deferred tax liabilities and tax planning strategies. To the extent management relies on deferred tax liabilities for the readability of our deferred tax assets, such deferred tax liabilities are expected to reverse in the same period and jurisdiction and are of the same character as the temporary differences giving rise to the deferred tax assets. We consider that the recovery of our current deferred tax assets is probable without counting on potential tax planning strategies that we could use in the future.

B.	Compensation

Compensation of Board of Directors and Chief Executive Officer

We paid compensation only to independent non-executive directors and executive directors. Since August 2018, each independent director receives an annual compensation of $134,000. As chairman of the audit committee, Mr. Francisco J. Martinez receives an additional $15,000 per year.

As chairman of the board of directors, Mr. Villalba receives an additional $61,000 per year.

Until August 2018, each independent director received a total annual compensation of $100,000 and as chairman of the board of directors, Mr. Villalba received an additional $35,000 per year. In 2018, each independent director received a total annual compensation detailed in the table below.

Non-executive directors appointed by Algonquin did not receive any compensation from us

Long-Term Incentive Plans

In 2016, we adopted our 2016-2018 LTIP for management, for the period from 2016 to 2018. Twelve executives, including our CEO, were eligible under LTIP. The LTIP provides that each eligible executive was entitled to the payment of a long-term incentive cash bonus in March 2019 calculated as a function of Total Annual Shareholder’s Return, or TSR, objectives over the 2016-18 period, a metric intended to align management and shareholder interests. The maximum bonus will be 50% (or, in the CEO’s case, 70%) of the total remuneration received by the executive over the period from 2016-18. Specifically, 50% of the bonus will be based on our TSR and 50% on the relative performance in terms of TSR versus a group of similarly structured companies selected by the Compensation Committee. In case of a change of control, the long-term incentives would become due and would be calculated using the offer price or the last price based on TSR up to and including the change of control. Given the actual TSR in the three-year period from January 1, 2016 and December 31, 2018 and the TSR versus the peer group during that same period, the amount payable under the LTIP amounts to 21.95% of the maximum potential amount, which represents a total amount of $1,618.0 thousand, expected to be paid in March 2019.

In April 2018, the Board of Directors approved the implementation of a long-term incentive plan for the 2019 period (the “Long-Term Incentive Plan” or “LTIP”) which permits the grant of share options and restricted stock units (“Awards”) to the executive team of the Company (the “Executives”). The LTIP applies to approximately 14 executives and the Board of Directors would also like to include the Chief Executive Officer, who is also a Director. The Chief Executive Officer’s participation in the LTIP will be submitted for shareholders’ approval at the 2019 annual general meeting.

The purpose of this LTIP is to attract and retain the best talent for positions of substantial responsibility in the Company, to encourage ownership in the Company by the executive team whose long-term service the Company considers essential to its continued progress and, thereby, encourage recipients to act in the shareholders’ interest and to promote the success the Company.

The aggregate number of shares which may be reserved for issuance under the LTIP must not exceed 2% of the number of the shares outstanding at the time of the Awards are granted but is expected to be significantly less. However, the Company may decide that, instead of issuing or transferring shares, the Executives may be paid in cash.

The value of the Awards will be defined as 50% of the Executives’ total annual compensation for the year closed before the date upon which an Award is granted and, in the case of the Chief Executive Officer, would be 70% of the same previous year total compensation at the grant date (“Awards Value”). The share options will represent 25% of the Award Value and the restricted stock units will represent 75% of the Award Value.

Main terms of the LTIP

	Share Options	Restricted Stock Units
Nature	Option cost shall be calculated by a third party using the Black-scholes or some other accepted methodology.	Conditions shall be based on continuing employment (or other service relationship) and/or achievement of a minimum 5% average annual total shareholders return (“TSR”).
Exercisability and vesting period	One-third of the total number of options awarded shall vest on each anniversary of the date upon which an award was granted. The Company will decide at vesting if cash or shares are given as payment.	The shares will vest on the third anniversary of the grant date but only if the total annual shareholders return (“TSR”) has been at least a 5% yearly average over such 3-year period.
Ownership and dividends	The participant shall have the rights of a shareholder only as to shares acquired upon the exercise of an option and not as to unexercised options. Until the Shares are issued or transferred, no right to vote at any meeting or to receive dividends or any other rights as a shareholder shall exist.	The participant will be entitled to receive, for each share unit, a payment equivalent to the amount of any dividend or distribution paid on one share between the grant date and the date on which the share unit vests.

169

Table of Contents

If a participant’s employment terminates by reason of involuntary termination (death, disability, retirement dismissal rendered unfair, etc.), any portion of his/her Award shall thereafter continue to vest and become exercisable according to the terms of the LTIP but such participant shall be no longer entitled to be granted Awards under the LTIP.

If a participant incurs a termination of employment for cause or voluntary resignation or withdrawal, options that have vested on the termination date will be exercisable within the period of 30 days from such termination date but any unvested Awards (options or restricted stock units) shall lapse.

If there is a change in control, all Awards shall vest in full on the date of the change in control. The participants must exercise their options within a period of 30 days.

If the Company is delisted, all outstanding Awards shall vest in full on the date of delisting and will be settled in cash. The cash payment for restricted stock units will be the last quoted share price of the Company and the cash payment for any outstanding share options will be the difference between the last quoted share price and the exercise price for the applicable option. Such cash payments will be made after applicable tax deductions within 30 days of the delisting.

In addition to the LTIP, in February 2019 the Board of Directors approved a special one-off plan which permits the grant of stock units to certain members of the Management and certain members of the Middle Management, consisting of approximately 25 managers. The value of the award will be defined as 50% of 2019 target remuneration (including salary and variable bonus). The share units will vest in 3 years, one third each year, provided that the manager is still an employee of the company.

The Chief Executive Officer LTIP, including the special one-off plan, will be submitted for shareholders’ approval at the 2019 annual general meeting expected to be held in June 2019.

The total compensation received by our independent directors and Chief Executive Officer from us during 2018 is set forth in the table below.

Total Shareholder Return and Chief Executive Officer Pay

The chart below shows the Company’s total shareholder return since June 2014, the date of our Initial Public Offering (“IPO”), until the end of 2018 compared with the total shareholder return of the companies in the Russell 2000 Index. The chart represents the progression of the return, including investment, starting from the time of the IPO at a 100%-point. In addition, dividends are assumed to have been re-invested at the closing price of each dividend payment date.

We believe the Russell 2000 Index is an adequate benchmark as it represents a broad range of companies of similar size.

TSR is calculated in US dollars.

Table of Contents

The increase in the number of employees for the year ended December 31, 2018 as compared to the year ended December 31, 2017 is mainly due to the personnel working in the Mini-Hydro plant acquired in Peru and the increase of headcount in our subsidiaries in Peru and South Africa, where we have terminated our services agreements with Abengoa.

E.	Share Ownership

None of our directors or members of our senior management is the owner of more than one percent of our ordinary shares, and no director or member of our senior management has voting rights with respect to our ordinary shares that are different from any other holder of our ordinary shares.

ITEM 7.

MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS

A.	Major Shareholders

The following table sets forth information with respect to beneficial ownership of our ordinary shares as of the date of this annual report by:

each of our directors and executive officers;

our directors and executive officers as a group; and

each person known to us to beneficially own 5% and more of our ordinary shares.

Beneficial ownership is determined in accordance with the rules and regulations of the SEC. It includes the sole or shared power to direct the voting or the disposition of the securities or to receive the economic benefit of the ownership of the securities. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, we have included shares that the person has the right to acquire within 60 days of this annual report, including through the exercise of any option or other right and the vesting of restricted shares. These shares, however, are not included in the computation of the percentage ownership of any other person. The calculations of percentage ownership in the table below is based on 100,217,260 ordinary shares outstanding as of the date of this annual report.

Name	Ordinary Shares Beneficially Owned		Percentage
Directors and Officers
Daniel Villalba		60,000		-
Santiago Seage		20,000		-
Jackson Robinson		8,647		-
Robert Dove		10,347		-

This information is based solely on the Schedule 13D filed on February 15, 2019 by Algonquin Power & Utilities Corp., a corporation incorporated under the laws of Canada, and Algonquin (AY Holdco) B.V., a corporation incorporated under the laws of the Netherlands, and AAGES (AY Holdings) B.V., a corporation incorporated under the laws of the Netherlands.

This information is based solely on the Schedule 13G filed on February 12, 2019 by Morgan Stanley and Morgan Stanley Investment Management Inc., corporations incorporated under the laws of Delaware. The registered address of both Morgan Stanley and Morgan Stanley Investment Management, Inc. is 1585 Broadway New York, NY 10036.

We have one class of ordinary shares, and each holder of our ordinary shares is entitled to one vote per share.

As of the date of this annual report, 100,217,260 of our ordinary shares were outstanding. Because some of our ordinary shares are held by brokers and other nominees, the number of shares held by and the number of beneficial holders with addresses in the United States is not fully ascertainable. As of the date of this annual report, to the best of our knowledge, one of our shareholders of record was located in the United States and held in the aggregate 100,217,259 ordinary shares representing approximately 99.99% of our outstanding shares. However, the United States shareholders of record include Cede & Co., which, as nominee for The Depositary Trust Company, is the record holder of all such ordinary shares. Accordingly, we believe that the shares held by Cede & Co. include ordinary shares beneficially owned by both United States and non-United States beneficial owners. As a result, these numbers may not accurately represent the number of beneficial owners in the United States.

B.	Related Party Transactions

Arrangements for Change in Control of the Company

On March 9, 2018, Algonquin completed an acquisition of a 25.0% stake in us from Abengoa with the option to acquire the remaining 16.5% stake. On April 17, 2018, Algonquin announced that it reached an agreement with Abengoa to acquire Abengoa’s remaining 16.5% stake. On November 27, 2018, Algonquin announced that they had completed the purchase of a 16.5% equity interest in Atlantica from Abengoa. With this purchase, Algonquin’s total equity interest in Atlantica is now 41.5% and Abengoa no longer has an equity interest in Atlantica.

Agre ements with Current Shareholders

We entered into the AAGES ROFO Agreement and Algonquin ROFO Agreement with AAGES and Algonquin, respectively.

Agreements with Former Shareholders

Most of our assets have an operation and maintenance agreement with Abengoa entities. Additionally, we entered into the Abengoa ROFO Agreement and Financial Support Agreement with Abengoa.

Operation and Maintenance Contracts at project-level

Most of our project-level companies have entered into an operation and maintenance agreement with an Abengoa subsidiary. The project-level entities which do not have an operation and maintenance agreement with Abengoa are ACT, Palmucho, Quadra 1, Quadra 2, Chile TL3, Seville PV and Melowind, where the contract is with third-party providers and Mini-hydro Peru where we provide the operation and maintenance services.

Term . Contract terms range from 20 to 30 years, typically mirroring the duration of financing contracts. The only exceptions are ATN, ATS, ATN2, Solaben 2/3 and Solacor 1/2 which are subject to shorter terms, with renewal clauses (as applicable).

Services . Contracts typically cover all day-to-day operation and maintenance services, including procurement of equipment, scheduling and performance of maintenance, operation of the facility, training and supervision of personnel, as well as compliance with laws and regulations, safety and security programs, environmental services and technical reporting.

Termination . Typically, either party may terminate the agreement upon default by the counterparty. The relevant project-level company that owns the asset can typically terminate due to payment default, winding-up of the operator, failure of the operator to perform material obligations, termination of the PPA and, in some cases, for failure to reach certain performance ratios, the imposition of fines or penalties in excess of certain threshold amounts or force majeure. The operator can typically terminate in the event of payment default, winding-up of the project-level company, failure of the project-level company to perform material obligations and, in some cases, force majeure. Some projects allow termination by us at certain points in time.

Compensation. Operation and maintenance contracts in Solana and Mojave provide for a fixed fee of approximately $500,000 per plant per year, which is indexed to U.S. CPI and a variable fee paid in periods in which net operating profit exceeds the target. In addition, the operator is entitled to reimbursement of certain costs. In other projects, including ATN, ATS and each of our solar power assets in Spain, the operation and maintenance contract provides for an all-in fee under which the operator must bear substantially all costs for the operation and maintenance of the plant.

Local Services Agreements

We no longer have local services agreements with Abengoa. After replacing them with our own local services employees in most of our assets in previous years, in 2018 we replaced Abengoa in South Africa for Kaxu and in Peru for ATN, ATS and ATN2.

Engineering, Procurement and Construction Agreements at project level

Each of the project-level companies that we purchased from Abengoa entered into an EPC contract with a local Abengoa subsidiary. These contracts typically provided for the construction of the asset and are in place until the asset reaches COD or production guarantees are met or paid. EPC contracts may contain warranties such as those against defects in design, materials and workmanship after completion of the asset and may also provide a performance guarantee. Most of the relevant obligations included in these contracts have expired, with the exception of defects in design as well as some obligations in Kaxu, Solana and Mojave.

AAGES Right of First Offer

Pursuant to the AAGES ROFO Agreement, which we and AAGES entered into on March 5, 2018 and which became effective upon completion of the 25% Share Sale, AAGES granted us a right of first offer on any proposed sale, transfer or other disposition of the AAGES’ ROFO Assets.

If AAGES transfers interests in any AAGES ROFO Asset, then AAGES must require such transferee to acquire the AAGES ROFO Asset subject to our right of first offer except under certain circumstances summarized below. The AAGES ROFO Agreement has an initial term of ten years.

Prior to engaging in any negotiation regarding any disposition, sale or other transfer of any asset, AAGES will deliver a written notice to us thereof, including a predefined set of information that is relevant for us to make a determination regarding the AAGES ROFO Asset, including the indicative price at which AAGES proposes to sell it to us. Once that information is received, a 60-day negotiation period will start. If an agreement is not reached, AAGES, during the following 30 months, may only sell, transfer, dispose or recontract such asset to a third party for an aggregate purchase price that is not less than 105% of the last purchase price we offered during the negotiation period for assets located outside Canada and the US. For U.S. or Canadian assets, the purchase price must not be less than 100% of the last purchase price we offered during the negotiation period.

Under the AAGES ROFO Agreement, AAGES is not obligated to sell any asset and, therefore, we do not know when, if ever, these assets will be offered to us. In addition, in some of the assets under the AAGES ROFO Agreement, AAGES may have equity partners with rights regulating divestitures by AAGES of its stake such as drag-along and tag-along clauses, and rights of first refusal, among others. We will consider and take into account all these clauses when deciding whether to present an offer.

Any material transaction between AAGES and us (including the proposed acquisition of any AAGES ROFO Asset) will be subject to our related party transaction policy, which will require prior approval of such transaction by a majority of the non-conflicted directors of our board of directors. See “—Procedures for Review, Approval and Ratification of Related Party Transactions;Conflicts of Interest,” “Item 3.D—Risk Factors—Risks Related to Our Relationship with Abengoa—We may not be able to consummate future acquisitions from AAGES, Algonquin or Abengoa” and “Item 3.D—Risk Factors.”

AAGES may enter into agreements with other companies with the objective of jointly developing the construction of new projects consisting of concessional assets which are included in AAGES’ current or future portfolio. Pursuant to the terms of the AAGES ROFO Agreement, AAGES may sell equity in these assets to third parties without being subject to the AAGES ROFO Agreement under certain circumstances in order to enhance the likelihood of success or financial prospects of such asset.

Algonquin Shareholders Agreement

In connection with the acquisition of 25.0% of our ordinary shares by Algonquin (indirectly through a subsidiary of AAGES), which completed in March 2018, we entered into a Shareholders Agreement with Algonquin and AAGES, which became effective upon completion of the 25% Share Sale. The Shareholders Agreement, among other things, sets forth certain rights and restrictions with respect to our ordinary shares, the main terms of which are summarized below.

Director Appointment Rights

The Shareholders Agreement provides that, if and to the extent provided in our articles, AAGES or Algonquin will have the right to appoint to our board the maximum number of directors that corresponds to AAGES’ and Algonquin’s holding of voting rights, as per articles of association but in any event no more than (i) such number of directors as corresponds to 41.5% of our voting securities; and (ii) 50% of our board less one, and if the resulting number is not a whole number, it shall be rounded up to the next whole number.

One of the directors appointed by AAGES and Algonquin holding in the aggregate at least 25.0% of our voting securities will have the right to be elected to any committee of our directors (except for the audit committee and related party transaction committee, and in those in which they are conflicted, or it is against the applicable law). In addition, so long as AAGES and Algonquin have the right to appoint a director and no such director is then serving on our board of directors, AAGES and Algonquin may appoint an observer to our board of directors and any committee thereof (except for the audit committee and related party transaction committee, and in those in which they are conflicted, or it is against the applicable law).

Dividends Distribution

We agreed that AAGES and Algonquin may terminate the Shareholders Agreement with respect to itself and its affiliates if, among others, our board of directors confirms a dividend payment objective that is lower than 80% of the cash available for distribution or our board of directors does not confirm any dividend payment objective at least once during any period of more than 14 consecutive months.

Pre-emption rights

AAGES and Algonquin may subscribe in cash for (i) up to 100% of our ordinary shares if the purpose of the issuance is to fund our acquisition of assets under the AAGES ROFO Agreement and Algonquin ROFO Agreement; and (ii) up to 66% of our ordinary shares if the purpose of the issuance is to fund our acquisition of assets under the Abengoa ROFO Agreement. If we issue ordinary shares for any other purpose, AAGES and Algonquin may subscribe in cash for ordinary shares in the amount pro rata to such AAGES’ and Algonquin’s aggregate holding of voting rights.

In addition, if AAGES and Algonquin elect to subscribe for at least 50% of an offering of our ordinary shares that will be listed, the price per ordinary share for all persons that participate in such offering will be equal to 97% of the USD volume-weighted average closing price per ordinary share on NASDAQ (or other applicable stock exchange) over the 20 trading days immediately preceding the date of AAGES’ and Algonquin’s receipt of notice of such proposed offering from us.

AAGES’/Algonquin’s Initial Funding Commitment

Subject to the approval of the board of directors of Algonquin, AAGES and Algonquin agreed to provide equity funding as required by us for the acquisition of assets and/or interests by us or our subsidiaries during 2018 and 2019, but no higher than $100 million.

Standstill

Algonquin will not acquire any of our voting securities which may result in AAGES and Algonquin holding in the aggregate more than 41.5% of the total voting rights. However, AAGES and Algonquin will not be in breach of this clause as a result of: (i) the acquisition of shares (or voting rights attached to such shares) by AAGES and Algonquin from Abengoa under the option agreement between Abengoa and Algonquin for the remaining 16.5% stake in us and (ii) the exercise of subscription rights as part of the Initial Funding Commitment described above. In such cases, until AAGES’ and Algonquin’s holding is again equal to or below 41.5%, AAGES and Algonquin cannot acquire any additional voting securities of us. The Shareholders Agreement further provides that in any case AAGES and Algonquin cannot acquire 46.0% or more of our voting securities or otherwise acquire control over us.

182

Table of Contents

Also, AAGES and Algonquin will not be in breach of the standstill restriction if the shareholding of AAGES and Algonquin has increased in connection with our action to reduce the number of our outstanding shares.

Termination

The Shareholders Agreement will terminate if, among others, AAGES and Algonquin and/or their affiliates cease to hold in the aggregate at least 10% of the total voting rights attached to our voting securities. In addition, Shareholders Agreement could terminate if, among others, the (i) our articles are amended in a manner that adversely affects the rights of AAGES and Algonquin to appoint directors, as such rights exist under our articles as of the date of the Shareholders Agreement; or (ii) we give notice to AAGES and Algonquin if: (a)(with respect to Algonquin and its affiliates only) a change of control over Algonquin occurs; or (b)(with certain exceptions) on three occasions AAGES and Algonquin have not subscribed for our ordinary shares in the amount of at least its pro rata share, or have not fully paid for subscribed ordinary shares; or (c)(with respect to Algonquin only) if the Algonquin ROFO Agreement terminates other than in connection with its breach by us.

Abengoa Right of First Offer

Pursuant to the Abengoa ROFO Agreement, which we and Abengoa entered into on June 13, 2014, as amended and restated on December 9, 2014, Abengoa and its affiliates granted us and our affiliates a right of first offer on any proposed sale, transfer or other disposition of any of their contracted renewable energy, efficient natural gas, electric transmission or water assets that are in operation and any other renewable energy, efficient natural gas, electric transmission and water asset that is expected to generate contracted revenue and that Abengoa has transferred to an investment vehicle that are located in our primary geographies: (i) North America (the United States, Canada and Mexico); (ii) the following countries in South America: Chile, Peru, Uruguay, Brazil and Colombia; and (iii) the European Union. In addition, with respect to selected countries in Africa, the Middle East and Asia, which we refer to as our secondary geographies, we agreed to four assets that are also considered within the scope of the Abengoa ROFO Agreement.

Whenever we acquire an asset from Abengoa in the secondary geographies, or, if after 60 days of negotiations we and Abengoa are unable to reach an agreement on an asset offered for sale to us, we will update the list to include a replacement asset. If we and Abengoa are unable to agree on the replacement asset, Abengoa will propose three additional assets in the secondary geographies and we will select one to replace the asset removed from the list. Thereafter, the selected asset will also be considered an asset under the Abengoa ROFO Agreement. This right of first offer will not apply to a merger with or into, or sale of a high percentage of Abengoa’s assets to, an unaffiliated third party, or to an internal restructuring.

If Abengoa transfers interests in any asset under the Abengoa ROFO Agreement to any affiliate or to an investment vehicle, then Abengoa must obtain an accession agreement from such transferee subjecting the transferred asset under the Abengoa ROFO Agreement to our right of first offer. For purposes of this requirement, “investment vehicle” means any person (A) (i) formed by Abengoa to act as an investment vehicle or (ii) that is an affiliate of Abengoa that Abengoa intends to use as an investment vehicle or becomes an investment vehicle due to an investment by a third party and (B) with the purpose of providing equity to projects related to any renewable energy, efficient natural gas, electric transmission line and water contracted revenue assets that are to be, are being or were previously developed, sponsored, initiated or launched by Abengoa or any of its affiliates, irrespective of the amount of equity invested in such person by Abengoa or any such affiliate. Abengoa Project Warehouse 1 qualifies as an “investment vehicle” and has agreed to be subject to the Abengoa ROFO Agreement.

In addition, we have a “negotiation call” right under which we can require Abengoa to negotiate in good faith for the sale to us of any asset under the Abengoa ROFO Agreement that has been in operation for 18 months.

The Abengoa ROFO Agreement has an initial term of five years from the consummation of our IPO and was extended until July 2022. We will be able to unilaterally extend the term of the Abengoa ROFO Agreement as many times as desired for an additional three-year period; provided that we have executed at least one acquisition in the previous two years after having been offered at least four projects.

Prior to engaging in any negotiation regarding any disposition, sale or other transfer of any asset under the Abengoa ROFO Agreement, Abengoa will deliver a written notice to us thereof, including a preliminary set of information that is relevant for us to make a determination regarding the asset under the Abengoa ROFO Agreement including the price at which Abengoa proposes to sell it to us. Once that information is received and if we do not notify Abengoa within 10 days that the information is insufficient, a 60-day negotiation period will start. If an agreement is not reached, Abengoa may, during the following 30 months, only sell, transfer, dispose or recontract such asset under the Abengoa ROFO Agreement to a third party (or to agree in writing to undertake such transaction with a third party) on terms and conditions generally no less favorable to Abengoa than those offered by Abengoa to us. If an asset that was already the subject of negotiations is presented again, we will have a 15-day period to negotiate. After such 30-month period, the asset will cease to be an asset under the Abengoa ROFO Agreement.

We will pay to Abengoa a fee of 1% of the equity purchase price of any asset under the Abengoa ROFO Agreement that we acquire as consideration for Abengoa granting us the right of first offer.

Under the Abengoa ROFO Agreement, Abengoa is not obligated to sell any asset under the Abengoa ROFO Agreement and, therefore, we do not know when, if ever, these assets will be offered to us. In addition, in some of the assets offered to us under the Abengoa ROFO Agreement, Abengoa may have equity partners with rights regulating divestitures by Abengoa of its stake such as drag-along and tag-along clauses, and rights of first refusal, among others. We will consider and take into account all these clauses when deciding whether to present an offer.

Abengoa may offer to sell to us contracted assets in business sectors or geographic regions not covered by the Abengoa ROFO Agreement, even though we do not have a ROFO over them as described in this section. We will evaluate these opportunities on a case-by-case basis.

Any transaction between Abengoa and us (including the proposed acquisition of any asset under the Abengoa ROFO Agreement) will be subject to our related party transaction policy, which will require prior approval of such transaction by a majority of the non-conflicted directors of our board of directors who would normally be independent as of the date hereof. See “—Procedures for Review, Approval and Ratification of Related Party Transactions; Conflicts of Interest,” “Item 3.D—Risk Factors—Risks Related to Our Relationship with Abengoa—We may not be able to consummate future acquisitions from AAGES, Algonquin or Abengoa” and “Item 3.D—Risk Factors.”

Abengoa may enter into agreements with other companies with the objective of jointly financing the construction of new projects consisting of concessional assets which are included in Abengoa’s current or future portfolio. Pursuant to the terms of the Abengoa ROFO Agreement, we expect that any investing vehicle created by Abengoa and a potential partner with this purpose will sign the Abengoa ROFO Agreement in the same terms of Abengoa.

Financial Support Agreement

We and Abengoa entered into a Financial Support Agreement on June 13, 2014, which was amended and restated September 28, 2017, for a period of five years, pursuant to which Abengoa will maintain any guarantees (whether Abengoa guarantees, bank guarantees, technical guarantees or otherwise) or letters of credit currently outstanding in our or any of our affiliates’ favor until June 2019. As of December 31, 2018, the aforementioned guarantees provided from Abengoa to our subsidiaries amounted to $23 million. We intend to replace these guarantees

Algonquin drop down agreement and Right of First Offer on assets outside the United States or Canada

Under the Algonquin ROFO Agreement, Algonquin agreed to periodically discuss with us the possibility of offering for sale interests in certain assets owned by Algonquin companies in Canada or the United States.

Pursuant to the Algonquin ROFO Agreement, which we and Algonquin entered into on March 5, 2018 and that became effective upon completion of the Share Sale, Algonquin granted us a right of first offer on any proposed sale, transfer or other disposition of any of their contracted facilities or infrastructure facilities located outside of the United States or Canada which are developed under expected long-term revenue agreements or concession agreements.

Table of Contents

If Algonquin transfers interests in any asset under the Algonquin ROFO Agreement, then Algonquin must require such transferee to acquire any asset under the Algonquin ROFO Agreement subject to our right of first offer except under certain circumstances summarized below. The Algonquin ROFO Agreement has an initial term of ten years.

Prior to engaging in any negotiation regarding any disposition, sale or other transfer of any asset under the Algonquin ROFO Agreement, Algonquin will deliver a written notice to us thereof, including a set of predefined information that is relevant for us to make a determination regarding any asset under the Algonquin ROFO Agreement, including the indicative price at which Algonquin proposes to sell it to us. Once that information is received, a 60-day negotiation period will start. If an agreement is not reached, Algonquin, during the following 30 months, may only sell, transfer, dispose or recontract such asset under the Algonquin ROFO Agreement to a third party for an aggregate purchase price that is not less than 105% of the last purchaser price we offered during the negotiation period.

Under the Algonquin ROFO Agreement, Algonquin is not obligated to sell any assets under the Algonquin ROFO Agreement and, therefore, we do not know when, if ever, these assets will be offered to us. In addition, in some of the assets under the Algonquin ROFO Agreement, Algonquin may have equity partners with rights regulating divestitures by Algonquin of its stake such as drag-along and tag-along clauses, and rights of first refusal, among others. We will consider and take into account all these clauses when deciding whether to present an offer.

Any material transaction between Algonquin and us (including the proposed acquisition of any asset under the Algonquin ROFO Agreement) will be subject to our related party transaction policy, which will require prior approval of such transaction by a majority non-conflicted directors of our board of directors. See “—Procedures for Review, Approval and Ratification of Related Party Transactions Policy; Conflicts of Interest,” “Item 3.D—Risk Factors—Risks Related to Our Relationship with Abengoa—We may not be able to consummate future acquisitions from AAGES, Algonquin or Abengoa” and “Item 3.D—Risk Factors.” In addition, Algonquin may terminate the Algonquin ROFO Agreement with us with a 180-day notice.

Procedures for Review, Approval and Ratification of Related Party Transactions; Conflicts of Interest

Our policy for the review, approval and ratification of related party transactions was updated and approved by the board of directors on February 28, 2018. Our policy requires that all transactions with related parties are subject to approval or ratification in accordance with the procedures set forth in the policy by the non-conflicted directors at the board of directors. With respect of any transaction with AAGES and Algonquin or its affiliates (other than our subsidiaries), including transactions pursuant to the ROFO agreements, the Related Party Transaction Committee is required to review all of the relevant facts and circumstances and report its conclusions to the board. A majority of non-conflicted directors are required to either approve or disapprove of the entry into the transaction. In determining whether to approve or ratify a transaction with AAGES, Algonquin or Abengoa, the directors unaffiliated with such entity are to consider, among other factors they may deem appropriate, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third-party under the same or similar circumstances and the extent of AAGES’, Algonquin’s or Abengoa’s interest in the transaction. Our Related Party Transaction Policy is available on our website at www.atlanticayield.com.

Code of Conduct

We have adopted a code of conduct applicable all directors, officers and employees of Atlantica Yield and our subsidiaries. The Code of Conduct is available on our website at www.atlanticayield.com , is communicated to all employees and is reviewed at least annually.

Dividend Policy

Our Cash Dividend Policy

We expect to pay a quarterly dividend on or about the 75th day following the expiration of the first, second and third fiscal quarters to our shareholders of record on or about the 60th day following the last day of such fiscal quarters. A quarterly dividend corresponding to the fourth quarter is usually declared in the first quarter of the following year. We expect to pay this dividend on or about the 82nd day following the expiration of the corresponding fourth fiscal quarter to our shareholders of record in general on or about the 72nd day following the last day of such fiscal quarter. However, there might be exceptions to these dates. Additionally, our board of directors may change our dividend policy at any point in time or modify the dividend for specific quarters following prevailing conditions.

We declared our first quarterly dividend in November 2014 and paid it on December 15, 2014. Since then, we declared and paid quarterly dividends in 2014 and 2015. On November 5, 2015, our board of directors approved a quarterly dividend corresponding to the third quarter of 2015. The dividend was paid on December 16, 2015, to shareholders of record as of November 30, 2015, and from that amount we retained $9 million of the dividend attributable to Abengoa in accordance with the provisions of the parent support agreement. See “Item 4.B—Business Overview—Electric Transmission—Exchangeable Preferred Equity Investment in Abengoa Concessões Brasil Holding.”

In February 2016, taking into consideration the uncertainties resulting from the situation of Abengoa, the board of directors decided to postpone the decision whether to declare a dividend in respect of the fourth quarter of 2015 until the second quarter of 2016. In May 2016, considering the uncertainties that remained in Abengoa’s situation, our board of directors decided not to declare a dividend in respect of the fourth quarter of 2015 and to postpone the decision on whether to declare a dividend in respect of the first quarter 2016 until we had obtained greater clarity on cross default and change of ownership issues. On August 3, 2016, the board of directors decided to declare a dividend of $0.145 per share for the first quarter of 2016 and a dividend of $0.145 per share for the second quarter of 2016. The dividend was paid on September 15, 2016, to shareholders of record August 31, 2016. From that amount, we retained $12.3 million of the dividend attributable to Abengoa. On November 11, 2016, our board of directors, based on waivers or forbearances obtained to that date, decided to declare a dividend of $0.163 per share, which was paid on December 15, 2016, to shareholders of record on November 30, 2016. From that amount, we retained $6.7 million of the dividend attributable to Abengoa.

On February 27, 2017, the board of directors declared a dividend of $0.25 per share corresponding to the fourth quarter of 2016, which was paid on March 15, 2017. From that amount, we retained $10.4 million of the dividend attributable to Abengoa. On May 15, 2017, the board of directors declared a dividend of $0.25 per share corresponding to the first quarter of 2017, which was paid on June 15, 2017. On August 3, 2017, the board of directors declared a dividend of $0.26 per share corresponding to the second quarter of 2017, which was paid on September 15, 2017. On November 10, 2017, our board of directors approved a dividend of $0.29 per share corresponding to the third quarter of 2017, which was paid on December 15, 2017.

On February 27, 2018, our board of directors approved a dividend of $0.31 per share corresponding to the fourth quarter of 2017 which was paid on March 27, 2018. On May 11, 2018, the board of directors declared a dividend of $0.32 per share corresponding to the first quarter of 2018, which was paid on June 15, 2018. On July 31, 2018, the board of directors declared a dividend of $0.34 per share corresponding to the second quarter of 2018, which was paid on September 15, 2018. On October 31, 2018, the board of directors declared a dividend of $0.36 per share corresponding to the third quarter of 2018 which was paid on December 14, 2018.

On February 26, 2019, our board of directors approved a dividend of $0.37 per share corresponding to the fourth quarter of 2018 which is expected to be paid on March 22, 2019 to shareholders of record March 12, 2019.

We intend to distribute a significant portion of our cash available for distribution as dividend, after considering the cash available for distribution that we expect our projects will be able to generate, less reserves for the prudent conduct of our business (including for, among other things, dividend shortfalls as a result of fluctuations in our cash flows), on an annual basis. We intend to distribute a quarterly dividend to shareholders. Our board of directors may, by resolution, amend the cash dividend policy at any time. We intend to grow our business via improvements in our existing projects and through the acquisition of operational projects when market conditions are favorable, which, we believe, will facilitate the growth of our cash available for distribution and enable us to increase our dividend per share over time. However, the determination of the amount of cash dividends to be paid to holders of our shares will be made by our board of directors and will depend upon our financial condition, results of operations, cash flow, long-term prospects and any other matters that our board of directors deem relevant.

186

Table of Contents

Our cash available for distribution is likely to fluctuate from quarter to quarter, in some cases significantly, as a result of the seasonality of our assets, the terms of our financing arrangements, maintenance and outage schedules, among other factors. Accordingly, during quarters in which our projects generate cash available for distribution in excess of the amount necessary for us to pay our stated quarterly dividend, we may reserve a portion of the excess to fund cash distributions in future quarters. In quarters in which we do not generate sufficient cash available for distribution to fund our stated quarterly cash dividend, if our board of directors so determines, we may use retained cash flow from other quarters, as well as other sources of cash, to pay dividends to our shareholders.

Risks Regarding Our Cash Dividend Policy

We do not have a significant operating history as an independent company upon which to rely in evaluating whether we will have sufficient cash available for distribution and other sources of liquidity to allow us to pay dividends on our shares at our initial quarterly dividend level on an annualized basis or at all. There is no guarantee that we will pay quarterly cash dividends to our shareholders. We do not have a legal obligation to pay our initial quarterly dividend or any other dividend. While we currently intend to grow our business and increase our dividend per share over time, our cash dividend policy is subject to all the risks inherent in our business and may be changed at any time as a result of certain restrictions and uncertainties, including the following:

The amount of our quarterly cash available for distribution could be impacted by restrictions on cash distributions contained in our project-level financing arrangements, which require that our project-level subsidiaries comply with certain financial tests and covenants in order to make such cash distributions. Generally, these restrictions limit the frequency of permitted cash distributions to semi-annual or annual payments, and prohibit distributions unless specified debt service coverage ratios, historical and/or projected, are met. See the sub-sections entitled “—Project Level Financing” under the individual project descriptions in “Item 4.B—Business Overview—Our Operations.” When forecasting cash available for distribution and dividend payments we have aimed to take these restrictions into consideration, but we cannot guarantee future dividends. In addition, restrictions or delays on cash distributions could also happen if our project finance arrangements are under an event of default. On January 29, 2019, PG&E, the off-taker for Atlantica Yield with respect to the Mojave plant, filed for reorganization under Chapter 11 of the Bankruptcy Code in the U.S. Bankruptcy Court for the Northern District of California. This situation could cause, among other consequences, restrictions to make cash distributions to the holding company. See “Item 3.D— Risk Factors. —Counterparties to our offtake agreements may not fulfill their obligations and, as our contracts expire, we may not be able to replace them with agreements on similar terms in light of increasing competition in the markets in which we operate”.

Additionally, indebtedness we have incurred under the 2019 Notes, the Revolving Credit Facility and the Note Issuance Facility contain, among other covenants, certain financial incurrence and maintenance covenants, as applicable. See “Item 5.B—Liquidity and Capital Resources—Financing Arrangements.” In addition, we may incur debt in the future to acquire new projects, the terms of which will likely require commencement of commercial operations prior to our ability to receive cash distributions from such acquired projects. These agreements likely will contain financial tests and covenants that our subsidiaries must satisfy prior to making distributions. Should we or any of our project-level subsidiaries be unable to satisfy these covenants or if any of us are otherwise in default under such facilities, we may be unable to receive sufficient cash distributions to pay our stated quarterly cash dividends notwithstanding our stated cash dividend policy. See the “Project Level Financing” descriptions contained in “Item 4.B—Business Overview—Our Operations” for a description of such restrictions.

187

Table of Contents

We and our board of directors have the authority to establish cash reserves for the prudent conduct of our business and for future cash dividends to our shareholders, and the establishment of or increase in those reserves could result in a reduction in cash dividends from levels we currently anticipate pursuant to our stated cash dividend policy. These reserves may account for the fact that our project-level cash flows may vary from year to year based on, among other things, changes in prices under offtake agreements, operational costs and other project contracts, compliance with the terms of project debt including debt repayment schedules, the transition to market or recontracted pricing following the expiration of offtake agreements, working capital requirements and the operating performance of the assets. Our board of directors may increase reserves to account for the seasonality that has historically existed in our assets’ cash flows and the variances in the pattern and frequency of distributions to us from our assets during the year. Furthermore, our board of directors may in the future increase reserves in light of the uncertainty associated with potential negative outcomes resulting from PG&E bankruptcy filing on January 29, 2019, including a potential event of default under the Mojave project finance agreement. If not cured or waived, an event of default in the project finance could result in debt acceleration and, if such amounts were not timely paid, the DOE could decide to foreclose on the asset. If not cured or waived, an event of default could also result in restrictions to make cash distributions from Mojave to the holding level. See “Item 3.D— Risk Factors—Counterparties to our offtake agreements may not fulfill their obligations and, as our contracts expire, we may not be able to replace them with agreements on similar terms in light of increasing competition in the markets in which we operate”. Our board of directors may increase reserves in light of the uncertainty associated with Abengoa’s financial condition to account for potential costs that we may incur or limitations that may be imposed upon us as a result of cross-defaults under our Kaxu project financing arrangements.

We may lack sufficient cash to pay dividends to our shareholders due to cash flow shortfalls attributable to a number of operational, commercial or other factors, including low availability, unexpected operating interruptions, legal liabilities, costs associated with governmental regulation, changes in governmental subsidies, changes in regulation, as well as increases in our operating and/or general and administrative expenses, principal and interest payments on our and our subsidiaries’ outstanding debt, income tax expenses, failure of Abengoa to comply with its obligations under the agreements in place, working capital requirements or anticipated cash needs at our project-level subsidiaries. See “Item 3.D—Risk Factors” for more information on the risks to which our business is subject.

We may pay cash to our shareholders via capital reduction in lieu of dividends in some years.

Our project companies’ cash distributions to us (in the form of dividends or other forms of cash distributions such as shareholder loan repayments) and, as a result, our ability to pay or grow our dividends, are dependent upon the performance of our subsidiaries and their ability to distribute cash to us. The ability of our project-level subsidiaries to make cash distributions to us may be restricted by, among other things, the provisions of existing and future indebtedness, applicable corporation laws and other laws and regulations.

Our board of directors may, by resolution, amend the cash dividend policy at any time. Our board of directors may elect to change the amount of dividends, suspend any dividend or decide to pay no dividends even if there is ample cash available for distribution.

Our Ability to Grow our Business and Dividend

We intend to grow our business primarily through the improvement of existing assets and the acquisition of contracted power generation assets, electric transmission lines and other infrastructure assets, which, we believe will facilitate the growth of our cash available for distribution and enable us to increase our dividend per share over time. Our policy is to distribute a significant portion of our cash available for distribution as a dividend. However, the final determination of the amount of cash dividends to be paid to our shareholders will be made by our board of directors and will depend upon our financial condition, results of operations, cash flow, long-term prospects and any other matters that our board of directors deems relevant.

We expect that we will rely primarily upon external financing sources, including commercial bank borrowings and issuances of debt and equity securities, to fund any future growth capital expenditures. To the extent we are unable to finance growth externally, our cash dividend policy could significantly impair our ability to grow because we do not currently intend to reserve a substantial amount of cash generated from operations to fund growth opportunities. If external financing is not available to us on acceptable terms, our board of directors may decide to finance acquisitions with cash from operations, which would reduce or even eliminate our cash available for distribution and, in turn, impair our ability to pay dividends to our shareholders. To the extent we issue additional shares to fund our business, our growth or for any other reason, the payment of dividends on those additional shares may increase the risk that we will be unable to maintain or increase our per share dividend level. Additionally, the incurrence of additional commercial bank borrowings or other debt to finance our growth would result in increased interest expense, which in turn may impact our cash available for distribution and, in turn, our ability to pay dividends to our shareholders.

Taxation

Material UK Tax Considerations

The following is a general summary of material UK tax considerations relating to the ownership and disposal of our shares. The comments set out below are based on current UK tax law as applied in England and Wales and HM Revenue & Customs, or HMRC, practice (which may not be binding on HMRC) as at the date of this summary, both of which are subject to change, possibly with retrospective effect. They are intended as a general guide and apply to you only if you are a “U.S. Holder” (as defined in the section below entitled “Material U.S. Federal Income Tax Considerations”) and if:

you hold Atlantica Yield shares as an investment for tax purposes, as capital assets and you are the absolute beneficial owner thereof for UK tax purposes; and

you are an individual, you are not resident in the United Kingdom for UK tax purposes and do not hold Atlantica Yield shares for the purposes of a trade, profession, or vocation that you carry on in the United Kingdom through a branch or agency, or if you are a corporation, you are not resident in the UK for UK tax purposes and do not hold the securities for the purpose of a trade carried on in the United Kingdom through a permanent establishment in the United Kingdom.

T his summary does not address all possible tax consequences relating to an investment in the shares. Certain categories of shareholders, including those falling outside the category described above, those carrying on certain financial activities, those subject to specific tax regimes or benefitting from certain reliefs or exemptions, those connected with us and those for whom the shares are employment-related securities may be subject to special rules and this summary does not apply to such shareholders and any general statements made in this disclosure do not take them into account.

This summary is for general information only and is not intended to be, nor should it be considered to be, legal or tax advice to any particular investor. It does not address all of the tax considerations that may be relevant to specific investors in light of their particular circumstances or to investors subject to special treatment under UK tax law.

Potential investors should satisfy themselves prior to investing as to the overall tax consequences, including, specifically, the consequences under UK tax law and HMRC practice of the acquisition, ownership and disposal of the shares in their own particular circumstances by consulting their own tax advisors.

UK Taxation of Dividends

We will not be required to withhold amounts on account of UK tax at source when paying a dividend in respect of our shares to a U.S. Holder.

U.S. Holders who hold their shares as an investment and not in connection with any trade carried on by them will not be subject to United Kingdom tax in respect of any dividends.

UK Taxation of Capital Gains

An individual holder who is a U.S. Holder will generally not be liable to UK capital gains tax on capital gains realized on the disposal of his or her Atlantica Yield shares unless such holder carries on (whether solely or in partnership) a trade, profession or vocation in the United Kingdom through a branch or agency in the United Kingdom to which the shares are attributable.

A corporate holder of shares that is a U.S. Holder will generally not be liable for UK corporation tax on chargeable gains realized on the disposal of its Atlantica Yield shares unless it carries on a trade in the United Kingdom through a permanent establishment to which the shares are attributable.

An individual holder of shares who is temporarily a non-UK resident for UK tax purposes will, in certain circumstances, become liable to UK tax on capital gains in respect of gains realized while he or she was not resident in the United Kingdom.

Stamp Duty and Stamp Duty Reserve Tax

The stamp duty and stamp duty reserve tax, or SDRT, treatment of the issue and transfer of, and the agreement to transfer, Atlantica Yield shares outside a depositary receipt system or a clearance service are discussed in the paragraphs under ‘General’ below. The stamp duty and SDRT treatment of such transactions in relation to such systems are discussed in the paragraphs under “Depositary Receipt Systems and Clearance Services” below.

General

No stamp duty, or SDRT, will arise on the issue of shares in registered form by Atlantica Yield.

An agreement to transfer our shares will normally give rise to a charge to SDRT at the rate of 0.5% of the amount or value of the consideration payable for the transfer. SDRT is, in general, payable by the purchaser.

Transfers of our shares will generally be subject to stamp duty at the rate of 0.5% of the consideration given for the transfer (rounded up to the next £5). The purchaser normally pays the stamp duty.

If a duly stamped transfer completing an agreement to transfer is produced within six years of the date on which the agreement is made (or, if the agreement is conditional, the date on which the agreement becomes unconditional) any SDRT already paid is generally repayable, normally with interest, and any SDRT charge yet to be paid is cancelled.

Depositary Receipt Systems and Clearance Services

Following the Court of Justice of the European Union’s decision in C-569/07 HSBC Holdings Plc, Vidacos Nominees Limited v The Commissioners of Her Majesty’s Revenue & Customs and the First-tier Tax Tribunal decision in HSBC Holdings Plc and The Bank of New York Mellon Corporation v. The Commissioners of Her Majesty’s Revenue & Customs, HMRC has confirmed that 1.5% SDRT is no longer payable when new shares are issued to a clearance service or depositary receipt system.

Where our shares are transferred (i) to, or to a nominee or an agent for, a person whose business is or includes the provision of clearance services or (ii) to, or to a nominee or an agent for, a person whose business is or includes issuing depositary receipts, stamp duty or SDRT will generally be payable at the higher rate of 1.5% of the amount or value of the consideration given or, in certain circumstances, the value of the shares.

Except in relation to clearance services that have made an election under Section 97A(1) of the Finance Act of 1986 (to which the special rules outlined below apply), no stamp duty or SDRT is payable in respect of transfers or agreements to transfer within clearance services or depositary receipt systems. Accordingly, no stamp duty or SDRT should, in practice, be required to be paid in respect of transfers or agreements to transfer our shares within the facilities of The Depository Trust Company, or DTC.

There is an exception from the 1.5% charge on the transfer to, or to a nominee or agent for, a clearance service where the clearance service has made and maintained an election under section 97A(1) of the Finance Act 1986, which has been approved by HMRC. In these circumstances, SDRT at the rate of 0.5% of the amount or value of the consideration payable for the transfer will arise on any transfer of our shares into such an account and on subsequent agreements to transfer such shares within such account. It is our understanding that DTC has not made an election under section 97A(1) of the Finance Act of 1986.

Any liability for stamp duty or SDRT in respect of any other transfer into a clearance service or depositary receipt system, or in respect of a transfer within any clearance service or depositary receipt system, which does arise will strictly be accountable by the clearance service or depositary receipt system operator or their nominee, as the case may be, but will, in practice, be payable by the participants in the clearance service or depositary receipt system.

Material U.S. Federal Income Tax Considerations

The following is a summary of material U.S. federal income tax consequences of the acquisition, ownership and disposition of shares by U.S. Holders (as defined below). This summary is based upon U.S. federal income tax laws (including the IRC, final, temporary and proposed Treasury regulations, rulings, judicial decisions and administrative pronouncements) all as of the date hereof and all of which are subject to changes in wording or administrative or judicial interpretation occurring after the date hereof, possibly with retroactive effect.

191

Table of Contents

As used herein, the term “U.S. Holder” means a beneficial owner of shares:

(a)

that is, for U.S. federal income tax purposes, (i) a citizen or resident of the United States, (ii) a corporation (or other entity taxable as a corporation) created or organized in or under the laws of the United States or any political subdivision thereof, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust, or the trust has validly elected to be treated as a domestic trust for U.S. federal income tax purposes;

(b)

that holds the shares as capital assets for U.S. federal income tax purposes; and

(c)

that owns, directly, indirectly or by attribution, less than 5% both of the vote and value of the interest in Atlantica Yield.

This summary does not cover all aspects of U.S. federal income taxation that may be relevant to, or the actual tax effect that any of the matters described herein will have on, the acquisition, ownership or disposition of shares by particular investors, and does not address state, local, foreign or other tax laws. This summary does not address all of the U.S. federal income tax considerations that may apply to U.S. Holders that are subject to special tax rules, such as U.S. citizens or lawful permanent residents of the United States living abroad, insurance companies, tax-exempt organizations, certain financial institutions, persons subject to the alternative minimum tax or the net investment income tax, dealers and certain traders in securities or currencies, persons holding shares as part of a straddle, hedging, conversion or other integrated transaction, partners in entities classified as partnerships for U.S. federal income tax purposes, persons holding shares through an individual retirement account or other tax-deferred account, persons whose functional currency is not the U.S. dollar or persons that carry on a trade, business or vocation in the United Kingdom through a branch, agency or permanent establishment to which the shares are attributable. Such U.S. holders may be subject to U.S. federal income tax consequences different from those set forth below.

If an entity classified as a partnership for U.S. federal income tax purposes holds shares, the U.S. federal income tax treatment of a partner in such an entity generally will depend upon the status of the partner and the activities of the partnership. An entity treated as a partnership for U.S. federal income tax purposes that holds shares and its partners are urged to consult their own tax advisors regarding the specific U.S. federal income tax consequences to the partnership and its partners of acquiring, owning and disposing of the shares.

This discussion assumes that Atlantica Yield is not, was not for its 2018 taxable year, and will not become a PFIC for U.S. federal income tax purposes, as discussed below under “—Passive foreign investment company rules.”

Potential investors in shares should consult their own tax advisors concerning the specific U.S. federal, state and local tax consequences of the ownership and disposition of shares in light of their particular situations as well as any consequences arising under the laws of any other taxing jurisdiction.

Taxation of distributions on the shares

Distributions received by a U.S. Holder on shares generally will constitute dividends to the extent paid out of Atlantica Yield current or accumulated earnings and profits (as determined for U.S. federal income tax purposes). Atlantica Yield intends to annually calculate its earnings and profits in accordance with U.S. federal income tax principles. If distributions exceed Atlantica Yield’s current and accumulated earnings and profits, such excess distributions will constitute a non-taxable return of capital to the extent of the U.S. Holder’s tax basis in its shares and will result in a reduction of such tax basis. To the extent such excess exceeds a U.S. Holder’s tax basis in the shares, such excess will generally be taxed as capital gain.

192

Table of Contents

Subject to certain exceptions for short-term and hedged positions, dividends received by certain non-corporate U.S. Holders of shares generally will be subject to U.S. federal income taxation at rates lower than those applicable to other ordinary income if the dividends are “qualified dividend income.” Distributions received by a U.S. Holder on shares will be qualified dividend income if: (i) shares are readily tradable on an established securities market in the United States (such as NASDAQ Global Select Market, where our shares are listed) and (ii) Atlantica Yield was not, for the year prior to the year in which the dividends are paid, and is not, for the year in which the dividends are paid, a PFIC. As discussed below under “—Passive foreign investment company rules,” although there can be no assurance that Atlantica Yield will not be considered a PFIC for any taxable year, Atlantica Yield does not believe that it was a PFIC for its 2018 taxable year and does not expect to be a PFIC for its current taxable year or in the foreseeable future. Non-corporate U.S. Holders should consult their own tax advisors to determine whether they are subject to any special rules that limit their ability to be taxed at these favorable rates. Corporate U.S. Holders will not be entitled to claim the dividends-received deduction with respect to dividends paid by Atlantica Yield. Dividends will be included in a U.S. Holder’s income on the date of the U.S. Holder’s receipt of the dividend.

Taxation upon sale or other disposition of shares

A U.S. Holder generally will recognize U.S. source capital gain or loss on the sale or other disposition of shares, which will generally be long-term capital gain or loss if the U.S. Holder has owned shares for more than one year. The amount of the U.S. Holder’s gain or loss will be equal to the difference between such U.S. Holder’s adjusted tax basis in the shares sold or otherwise disposed of and the amount realized on the sale or other disposition. Net long-term capital gain recognized by certain non-corporate U.S. Holders will be taxed at a lower rate than the rate applicable to ordinary income. The deductibility of capital losses is subject to limitations.

Passive foreign investment company rules

If Atlantica Yield were a PFIC for any taxable year during which a U.S. Holder held shares, certain adverse U.S. federal income tax consequences may apply to the U.S. Holder. Atlantica Yield does not believe that it was a PFIC for its 2018 taxable year and does not expect to be a PFIC for its current taxable year or in the foreseeable future. However, PFIC status depends on the composition of a company’s income and assets and the fair market value of its assets (including, among others, less than 25% owned equity investments) from time to time, as well as on the application of complex statutory and regulatory rules that are subject to potentially varying or changing interpretations. Accordingly, there can be no assurance that Atlantica Yield will not be considered a PFIC for any taxable year.

A non-U.S. corporation will be a PFIC in any taxable year in which, after taking into account the income and assets of the corporation and certain subsidiaries pursuant to applicable “look-through rules,” either: (i) at least 75% of its gross income is “passive income” or (ii) at least 50% of the average value of its assets is attributable to assets which produce passive income or are held for the production of passive income. For purposes of the PFIC rules, “passive income” includes, among other things, certain foreign currency gains, certain rents and the excess of gains over losses from certain commodities transactions. Gains from commodities transactions, however, are generally excluded from the definition of passive income if such gains are active business gains from the sale of commodities and the foreign corporation’s commodities meet specified criteria. The law is unclear as to what constitutes “active business gains” and there are also other uncertainties regarding the criteria that commodities must meet. Accordingly, there can be no assurance that Atlantica Yield is not, was not for its 2018 taxable year, or will not become a PFIC or that changes in the management or ownership structure of Atlantica Yield or its assets, including as a result of any acquisitions pursuant to the ROFO agreements, will not impact the determination of Atlantica Yield’s PFIC status.

If Atlantica Yield were a PFIC for any taxable year during which a U.S. Holder held shares, gain recognized by a U.S. Holder on a sale or other disposition of the shares would generally be allocated ratably over the U.S. Holder’s holding period for the shares. The amounts allocated to the taxable year of the sale or other disposition and to any year before Atlantica Yield became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to U.S. federal income tax at the highest rate in effect in that year for individuals or corporations, as appropriate, and an interest charge would be imposed on the resulting U.S. federal income tax liability. The same treatment would generally apply to any distribution in respect of shares to the extent the distribution exceeds 125% of the average of the annual distributions on shares received by the U.S. Holder during the preceding three years or the U.S. Holder’s holding period, whichever is shorter. Certain elections may be available that would result in alternative treatments (such as mark-to-market treatment) of the shares.

In addition, if Atlantica Yield were a PFIC for a taxable year in which it pays a dividend or in the prior taxable year, the favorable dividend rate discussed above with respect to dividends paid to certain non-corporate U.S. Holders would not apply.

193

Table of Contents

U.S. Holders should consult their own tax advisors regarding the PFIC rules.

Information reporting and backup withholding

Payments of dividends and sales proceeds that are made within the United States or through certain U.S. financial intermediaries generally are subject to information reporting and to backup withholding unless the U.S. Holder is a corporation or other exempt recipient, or, in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the U.S. Holder’s U.S. federal income tax liability and may entitle such U.S. Holder to a refund, provided that the required information is timely furnished to the Internal Revenue Service. U.S. Holders should consult their own tax advisors about these rules and any other reporting obligations that may apply to the ownership or disposal of shares, including requirements related to the holding of certain “specified foreign financial assets.”

ITEM 11.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Quantitative and Qualitative Disclosure about Market Risk

Our activities are undertaken through our segments and are exposed to market risk, credit risk and liquidity risk. Risk is managed by our Risk Management and Finance Department in accordance with mandatory internal management rules. The internal management rules provide written policies for the management of overall risk, as well as for specific areas, such as exchange rate risk, interest rate risk, credit risk, liquidity risk, use of hedging instruments and derivatives and the investment of excess cash.

194

Table of Contents

Market risk

We are exposed to market risk, such as movement in foreign exchange rates and interest rates. All of these market risks arise in the normal course of business and we do not carry out speculative operations. For the purpose of managing these risks, we use a series of swaps and options on interest rates and foreign exchange rates. None of the derivative contracts signed has an unlimited loss exposure.

Foreign exchange rate risk

The main cash flows from our subsidiaries are cash collections arising from long-term contracts with clients and debt payments arising from project finance repayment. Given that financing of the projects is always denominated in the same currency in which the contract with the client is signed, a natural hedge exists for our main operations.

Our functional currency is the U.S. dollar, as most of our revenues and expenses are denominated or linked to U.S. dollars. All our companies located in North America, South America and Algeria have their PPAs, or concessional agreements, and financing contracts signed in, or indexed to, U.S. dollars. Our solar power plants in Spain have their revenues and expenses denominated in euros. Revenues and expenses of Kaxu, our solar plant in South Africa, are denominated in South African rand. While fluctuations in the value of the euro and the South African rand may affect our operating results, we hedge cash distributions from our Spanish assets. Our strategy is to hedge the exchange rate for the distributions from our Spanish assets after deducting euro-denominated interest payments and euro-denominated general and administrative expenses. Through currency options, we hedge 100% of the net euro net exposure for the next 12 months and 75% of the net euro net exposure for the following 12 months.

Since we hedge cash flows, fluctuations in the value of foreign currencies (the euro and the South African rand) in relation to the U.S. dollar may affect our operating results.

Interest rate risk

Interest rate risks arise mainly from our financial liabilities at variable interest rate (less than 10% of our total project debt financing). We use interest rate swaps and interest rate options (caps) to mitigate interest rate risk.

As a result, the notional amounts hedged as of December 31, 2018, contracted strikes and maturities, depending on the characteristics of the debt on which the interest rate risk is being hedged, are very diverse, including the following:

Project debt in euro: between 81% and 100% of the notional amount, maturities until 2030 and average guaranteed interest rates of between 0.60% and 4.87%

Project debt in U.S. dollars: between 70% and 100% of the notional amount, maturities until 2034 and average guaranteed interest rates of between 2.32% and 5.27%

In connection with our interest rate derivative positions, the most significant impact on our Annual Consolidated Financial Statements are derived from the changes in EURIBOR or LIBOR, which represents the reference interest rate for the majority of our debt.

In relation to our interest rate swaps positions, an increase in EURIBOR or LIBOR above the contracted fixed interest rate would create an increase in our financial expense which would be positively mitigated by our hedges, reducing our financial expense to our contracted fixed interest rate. However, an increase in EURIBOR or LIBOR that does not exceed the contracted fixed interest rate would not be offset by our derivative position and would result in a net financial loss recognized in our consolidated income statement. Conversely, a decrease in EURIBOR or LIBOR below the contracted fixed interest rate would result in lower interest expense on our variable rate debt, which would be offset by a negative impact from the mark-to-market of our hedges, increasing our financial expense up to our contracted fixed interest rate, thus likely resulting in a neutral effect.

195

Table of Contents

In relation to our interest rate options positions, an increase in EURIBOR or LIBOR above the strike price would result in higher interest expenses, which would be positively mitigated by our hedges, reducing our financial expense to our capped interest rate, whereas a decrease of EURIBOR or LIBOR below the strike price would result in lower interest expenses.

In addition to the above, our results of operations can be affected by changes in interest rates with respect to the unhedged portion of our indebtedness that bears interest at floating rates.

In the event that EURIBOR and LIBOR had risen by 25 basis points as of December 31, 2018, with the rest of the variables remaining constant, the effect in the consolidated income statement would have been a loss of $2.7 million (a loss of $1.1 million in 2017 and a loss of $2.6 million in 2016) and an increase in hedging reserves of $32.9 million ($39.1 million in 2017 and $37.2 million in 2016). The increase in hedging reserves would be mainly due to an increase in the fair value of interest rate swaps designated as hedges.

Credit risk

During recent months, the credit rating of Eskom has also weakened and is currently CCC+ from S&P, B2 from Moody’s and BB- from Fitch. Eskom is the offtaker of our Kaxu solar plant, a state-owned, limited liability company, wholly owned by the government of the Republic of South Africa. Eskom’s payment guarantees to our solar plant Kaxu are underwritten by the South African Department of Energy, under the terms of an implementation agreement. The credit ratings of the Republic of South Africa as of the date of this report are BB/Baa3/BB+ by S&P, Moody’s and Fitch, respectively.

Apart from these two situations, we consider that in general we have limited credit risk with clients as revenues are derived from PPAs and other revenue contracted agreements with electric utilities and state-owned entities.

The following table shows the maturity detail of trade receivables as of December 31, 2018, 2017 and 2016:

	Balance as of December 31,
	2018		2017		2016

Between 3 and 6 months		—		—		—
Total		163.9		186.7		151.2

Liquidity risk

The objective of our financing and liquidity policy is to ensure that we maintain sufficient funds to meet our financial obligations as they fall due.

Project finance borrowing permits us to finance projects through project debt and thereby insulate the rest of our assets from such credit exposure. We incur project finance debt on a project-by-project basis.

The repayment profile of each project is established on the basis of the projected cash flow generation of the business. This ensures that sufficient financing is available to meet deadlines and maturities, which mitigates the liquidity risk

CONTROLS AND PROCEDURES

(a)

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the U.S. Exchange Act, that are designed to ensure that information required to be disclosed by the Company in reports that we file or submit under the U.S. Exchange Act is (i) recorded, processed, summarized and reported within the time period specified in the SEC’s rules and forms; and (ii) accumulated and communicated to our management, including our Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer), as appropriate, to allow timely decisions regarding required disclosure. Disclosure controls and procedures, no matter how well designed, can provide only reasonable assurance of achieving the desired control objectives.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has performed an evaluation of the effectiveness of the design and operation of its disclosure controls and procedures (as defined in Rule 13a-15 (e) under the Exchange Act) as of December 31, 2018. There are inherent limitations to the effectiveness of any control system, including disclosure controls and procedures.

Based upon their evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective.

Management’s Report on Internal Control over Financial Reporting

Pursuant to Section 404 of the United States Sarbanes-Oxley Act, management is responsible for establishing and maintaining effective internal control over financial reporting. This system is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

197

Table of Contents

Because of its inherent limitations, internal control over financial reporting may not prevent or detect all misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2018, based on the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO, in Internal Control—Integrated Framework (2013). Based on this assessment, management concluded that, as of December 31, 2018, its internal control over financial reporting was effective based on those criteria.

Our internal control over financial reporting as of December 31, 2018, has been audited by Deloitte S.L., an independent registered public accounting firm, as stated in their report which follows below.

Attestation Report of the Independent Registered Public Accounting Firm

The report of Deloitte, S.L., our Independent Registered Public Accounting Firm, on our internal control over financial reporting is included herein at page F-2 of our Annual Consolidated Financial Statements.

Changes in Internal Controls over Financial Reporting

There has been no change in our internal control over financial reporting that occurred during 2018 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations of Disclosure Controls and Procedures in Internal Control over Financial Reporting

It should be noted that any system of controls, however well-designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of the system will be met. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of future events. Projections regarding the effectiveness of a system of controls in future periods are subject to the risk that such controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with the policies or procedures.

“Audit Fees” are the aggregate fees billed for professional services in connection with the audit of our Annual Consolidated Financial Statements, quarterly reviews of our interim financial statements and statutory audits of our subsidiaries’ financial statements under the rules of England and Wales and the countries in which our subsidiaries are organized. The increase in audit fees is mainly due to foreign exchange differences.

“Audit-Related Fees” include fees charged for services that can only be provided by our auditor, such as audits of non-recurring transactions, consents, comfort letters, attestation services and audit services required for SEC or other regulatory agencies. Audit-Related fees also includes assurance and related services that are reasonably related to the performance of the audit or review of our financial statements. Fees paid during 2018 related to comfort letters and consents required for capital market transactions of our major shareholder are also included in this category.The Audit Committee approved all of the services provided by Deloitte, S.L. and by other member firms of Deloitte.

“All Other Fees” comprises fees billed in relation to financial advisory services and other services which cannot be comprised under other categories.

Audit Committee’s Policy on Pre-Approval of Audit and Permissible Non-Audit Services of the Independent Auditor

Subject to the approval of the independent auditor by our shareholders, the Audit Committee has the sole authority to appoint, retain or replace the independent auditor. The Audit Committee is also directly responsible for the compensation and oversight of the work of the independent auditor. These policies generally provide that we will not engage our independent auditors to render audit or non-audit services unless the service is specifically approved in advance by the Audit Committee. The Audit Committee’s pre-approval policy, which covers audit and non-audit services provided to us or to any of our subsidiaries, is as follows:

The Audit Committee shall review and approve in advance the annual plan and scope of work of the independent external auditor, including staffing of the audit, and shall (i) review with the independent external auditor any audit-related concerns and management’s response and (ii) confirm that any examination is performed in accordance with the relevant accounting standards;

The Audit Committee shall pre-approve all audit services, and all permitted non-audit services (including the fees and terms thereof) to be performed for us by the independent auditors, to the extent required by law. The Audit Committee may delegate to one or more Committee members the authority to grant pre-approvals for audit and permitted non-audit services to be performed for us by the independent auditor, provided that decisions of such members to grant pre-approvals shall be presented to the full Audit Committee at its next regularly scheduled meeting;

199

Table of Contents

The list of audit services and all permitted non-audit services (including the fees and terms thereof) to be performed for us by the independent auditors pre-approved by the Audit Committee, considering that these services clearly allowed from the point of independence is the following:

Audit services, including audit of financial statements, limited reviews, comfort letters, other verification works requested by regulator or supervisors;

Audit-related services, including due diligence services, verification of corporate social responsibility report, accounting or internal control advisory and preparation courses on these topics;

Tax services;

Other specific services, such as evaluation of the design, implementation and operation of a financial information system or control over financial reporting; and

Courses or seminars.

Only for information purposes, all audit and non-audit services will be reported to the Audit Committee on a quarterly basis.

Any other service shall be pre-approved by the Audit Committee. However, when for reasons of urgency, it is necessary to start the provision of services prior to the next meeting of the Audit Committee, the Chairman of the Audit Committee is authorized to provide such approval, which shall be communicated to the Audit Committee subsequently.

In accordance with the above pre-approval policy, all audit and permitted non-audit services performed for us by our principal accountants, or any of its affiliates, were approved by the Audit Committee of our board of directors, who concluded that the provision of such services by the independent accountants was compatible with the maintenance of that firm’s independence in the conduct of its auditing functions: an auditor may not function in the role of management; an auditor may not audit his or her own work; and an auditor may not serve in an advocacy role for his or her client.

The Audit Committee approved all the services provided by Deloitte, S.L.

CHANGE IN REGISTRANT’S CERTIFYING ACCOUNTANT

On May 21, 2018, we announced that the Annual General Meeting of Shareholders of the Company, held on May 11, 2018, voted to appoint Ernst & Young LLP and Ernst & Young, S.L. (collectively, “EY”) to be our independent registered public accounting firm for up to four years starting on January 1, 2019

On February 27, 2018, the Board of Directors of Atlantica, resolved to propose to the Annual General Meeting of Shareholders of the Company, the appointment of EY as new auditor. Such selection was adopted at the proposal of the audit committee in accordance with the corporate governance guidelines recommending periodic rotation of the independent registered public accounting firm, following a transparent selection process. As a consequence, Deloitte, S.L. was released as the independent registered public accounting firm of the Company as of February 28, 2019.

The reports of Deloitte, S.L. on the audits related our financial statements and the effectiveness of internal control over financial reporting for the past two fiscal years did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. There was no disagreement whatsoever relating to the years ended December 31, 2018, 2017, and 2016 and the period from January 1, 2019 through February 28, 2019 with Deloitte, S.L. on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement, if not resolved to the satisfaction of Deloitte, S.L. would have caused them to make reference to the subject matter of the disagreement in connection with their reports, or any “reportable event” as described in Item 16F(a)(1)(v) of Form 20-F.

We have provided a copy of the above statements to Deloitte, S.L. and requested that Deloitte, S.L. furnish us with a letter addressed to the SEC stating whether or not they agree with the above disclosure. A copy of that letter, dated February 28, 2019, is filed as exhibit 15.3 to this Annual Report.

ITEM 16G.

CORPORATE GOVERNANCE

Under U.S. federal securities laws and NASDAQ rules we are a “foreign private issuer.” Under NASDAQ Stock Market Rule 5615(a)(3), a foreign private issuer may follow home country corporate governance practices instead of certain of NASDAQ's requirements, provided that such foreign private issuer discloses in its annual report filed with the SEC each requirement of Rule 5600 that it does not follow and describes the home country practice followed in lieu of such requirement. In addition, a foreign private issuer that elects to follow a home country practice instead of NASDAQ’s requirements must submit to NASDAQ a written statement from an independent counsel in such issuer’s home country certifying that the issuer’s practices are not prohibited by the home country’s laws.

As a foreign private issuer and as a UK company, we are not required to and we do not have: (i) a nominating/corporate governance committee composed entirely of independent directors and (ii) a compensation committee composed entirely of independent directors or (iii) an annual performance evaluation of the nominating/corporate governance and compensation committees. These exemptions do not modify the independence requirements for the audit committee, and we currently comply with the requirements of the Sarbanes-Oxley Act and the NADSAQ rules with respect to the audit committee.

Other than the matters described above, there are no significant differences between our corporate governance practices and those followed by U.S. domestic companies under Nasdaq Stock Market Rules.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Atlantica Yield plc:

Opinion on the Financial Statements

We have audited the accompanying consolidated statements of financial position of Atlantica Yield plc and subsidiaries (the "Company") as of December 31, 2018 and 2017, and the related consolidated income statements, the consolidated statements of comprehensive income, the consolidated statements of changes in equity and the consolidated cash flow statements for each of the three years in the period ended December 31, 2018, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2018, based on the criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 26, 2019, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Atlantica Yield plc:

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Atlantica Yield plc and subsidiaries (the “Company”) as of December 31, 2018, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2018, of the Company and our report dated February 26, 2019, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting . Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Note 1.- Nature of the business

Atlantica Yield plc (“Atlantica” or the “Company”) was incorporated in England and Wales as a private limited company on December 17, 2013 under the name Abengoa Yield Limited. On March 19, 2014, the Company was re-registered as a public limited company, under the name Abengoa Yield plc. On May 13, 2016, the change of the Company´s registered name to Atlantica Yield plc was filed with the Registrar of Companies in the United Kingdom.

Atlantica is a total return company that owns, manages and acquires renewable energy, efficient natural gas, electric transmission lines and water assets focused on North America (the United States and Mexico), South America (Peru, Chile and Uruguay) and EMEA (Spain, Algeria and South Africa).

Atlantica’s shares began trading on the NASDAQ Global Select Market under the symbol “ABY” on June 13, 2014. The symbol changed to “AY” on November 11, 2017.

On March 9, 2018 and on November 27, 2018, Algonquin Power & Utilities (“Algonquin”) announced that it completed the acquisition from Abengoa S.A, (“Abengoa”) of a 25% and 16.47% equity interest in Atlantica, respectively. Algonquin is the largest shareholder of the Company which currently owns a 41.47% stake in Atlantica Yield. Algonquin does not consolidate the Company in its consolidated financial statements.

During 2016, the Company closed the acquisition of a 13% stake in Solacor 1/2 from the JGC Corporation (“JGC”), which reduced the JGC´s ownership in Solacor 1/2 to 13%, and of an 80% stake in Fotovoltaica Solar Sevilla, S.A. (“Seville PV”) from Abengoa, a 1 MW solar photovoltaic plant in Spain.

On February 28, 2017, the Company closed the acquisition of a 12.5% interest in a 114-mile transmission line in the U.S. from Abengoa. The asset will receive a Federal Energy Regulatory Commission (“FERC”) regulated rate of return, and is currently under development, with Commercial Operation Date (“COD”) expected in 2020.

During the year 2018, the Company completed the following acquisitions:

On February 28, 2018, the Company closed the acquisition of a 100% stake in a 4 MW hydroelectric power plant in Perú (“Mini-Hydro”) for approximately $9 million;

On December 11, 2018, the Company closed the acquisition of a 66kV transmission line in operation in Chile (“Chile TL3”) for approximately $6 million;

On October 10, 2018, the Company completed the acquisition of a 5% stake in a natural gas transportation in Mexico (Pemex Transportation System or “PTS”). Consideration for this 5% stake, which amounts to approximately $7 million, will be disbursed progressively as construction progresses;

On December 14, 2018, the Company closed the acquisition of a 100% stake in a 50 MW on-shore wind plant in Uruguay (“Melowind”) for approximately $45 million;

On December 28, 2018, the Company completed the acquisition of a transmission line, which is an extension of ATN (“ATN expansion 1”) for approximately $16 million.

On November 27, 2015, Abengoa, reported that, it filed a communication pursuant to article 5 bis of the Spanish Insolvency Law 22/2003 with the Mercantile Court of Seville nº 2. On November 8, 2016, the Judge of the Mercantile Court of Seville declared judicial approval of Abengoa´s restructuring agreement. On March 31, 2017 Abengoa announced the completion of the restructuring. As a result, Atlantica Yield received Abengoa debt and equity instruments in exchange of the guarantee previously provided by Abengoa regarding the preferred equity investment in Abengoa Concessoes Brasil Holding (“ACBH”).

In addition, in Solana and Mojave, in November 2017, in the context of the agreement reached between Abengoa and Algonquin for the acquisition by Algonquin of 25% of the shares of the Company and based on the obligations of Abengoa under the EPC contract, the Company signed a consent with the DOE which reduced this minimum ownership required by Abengoa in Atlantica Yield to 16%, which became effective upon closing of the transaction on March 9, 2018, when Abengoa announced it made effective the sale of a 25% stake in Atlantica Yield to Algonquin. In addition, the DOE approved on November 27, 2018 the sale to Algonquin of the residual stake of 16.47% in the Company held by Abengoa, canceling any residual change of ownership clause of previous agreements.

These consolidated financial statements were approved by the Board of Directors of the Company on February 26, 2019.

The applications of these amendments have not had any material impact on these consolidated financial statements.

F-16

In relation to IFRS 15, IFRS 9 and IFRS 16, the Company performed the following analysis:

IFRS 15 ‘Revenues from contracts with Customers’

In May 2014, the IASB (International Accounting Standards Board) published IFRS 15 “Recognition of Revenue from Contracts with Customers”. This Standard brings together all the applicable requirements and replaces the current standards for recognizing revenue: IAS 11 Construction Contracts, IAS 18 Revenue, IFRIC 13 Customer Loyalty Program, IFRIC 15 Agreements for the Construction of Real Estate, IFRIC 18 Transfers of Assets from Customers and SIC-31 Revenue—Barter Transactions Involving Advertising Services.

The new requirements may lead to changes in the current revenue profile, since the Standard’s main principle is that the Company must recognize its revenue in accordance with the transfer of goods or services to the customers in an amount which reflects the consideration that the Company expects to receive in exchange for these goods or services. The model laid out by the Standard is structured in five steps:

Step 1: Identifying the contract with the customer.

Step 2: Identifying the performance obligations.

Step 3: Determining the transaction price.

Step 4: Assigning the transaction price in the performance obligations identified in the contract.

Step 5: Recognition of revenue when (or as) the Company performs the performance obligations.

Contracted concessional assets and price purchase agreements (PPAs) include fixed assets financed through project debt, related to service concession arrangements recorded in accordance with International Financial Reporting Interpretations Committee 12 (“IFRIC 12”), except for Palmucho, which is recorded in accordance with IAS 17 and PS10, PS20, Seville PV, Mini-hydro and Chile TL3, which are recorded as tangible assets in accordance with IAS 16. The infrastructures accounted for by the Company as concessions are related to the activities concerning electric transmission lines, solar electricity generation plants, efficient natural gas plants, wind farms and water plants.

Currently, assets recorded in accordance with IFRIC 12 are classified as intangible assets or as financial assets, depending on the nature of the payment entitlements established in the contracts.

According to IFRS 15, the Company should assess the goods and services promised in the contracts with the customers and shall identify as a performance obligation each promise to transfer to the customer a good or service (or a bundle of goods or services).

In the case of contracts related to financial assets, the Company has identified two performance obligations (construction and operation of the asset). The contracts state that each service (construction and operation) has its own transaction price. For this reason, both performance obligations are separately identifiable in the context of the contract. The Company must allocate the total consideration to be received by the contract to each performance obligation. As mentioned above, the different services performed have been identified as two different performance obligations (construction and operation). Each performance obligation has its own transaction price stated in the contract. Such transaction prices are agreed in the contract by the parties in an orderly transaction, with no interrelation between both transaction prices and therefore correspond to the fair value of the goods and services provided in each case. As a result, for IFRS 15 purposes, the total transaction price will be allocated to each performance obligation in accordance with the two transaction prices stated within the contract, as they represent the respective fair values of the identified performance obligations.

For the assets classified as intangible assets, the Company has identified the same performance obligations, (construction and operation), but in this case the consideration received by the Company for the construction services is a license. The grantor makes a non-cash payment for the construction services by giving the operator an intangible asset. When allocating fair value for IFRS 15 purposes, the Company will recognize as revenue for the first performance obligation the fair value of the construction services, and the amount corresponding to the sales of energy as the fair value of second performance obligation (operation).

F-17

Additionally, in both cases, the services are satisfied over time. All the concessional assets of the Company are in operation and the Company satisfies the performance obligations and recognizes revenue over time. The same conclusion applies to concessional assets that are classified as tangible assets or leases.

IFRS 15 also incorporates specific criteria to determine which costs relating to a contract should be capitalized by distinguishing between incremental costs of obtaining a contract and costs associated with fulfilling a contract. No significant costs of obtaining a contract or compliance (other than those that are already capitalized) have been identified.

As the practice for revenue recognition applied until December 31, 2017, is consistent with the analysis above under IFRS 15, the Company considers that the adoption of this standard has no impact in the consolidated financial statements of the Company.

Also, the Company adopted IFRS 15 applying the full retrospective method to each prior reporting period presented, but without changes in the comparative reporting periods as the adoption of the standard has no effect in the consolidated financial statements.

IFRS 9 ‘Financial Instruments’

IFRS 9 Financial Instruments issued on 24 July 2014 is the IASB’s replacement of IAS 39 Financial Instruments: Recognition and Measurement. The standard addresses the classification, measurement and derecognition of financial assets and financial liabilities, introduces new rules for hedge accounting and a new impairment model for financial assets. The Company adopted the standard as of January 1, 2018, including the new requirements for hedge accounting. The Company adopted retrospectively without re-expressing comparative periods. The analysis performed by the Company is as follows:

-	Classification and measurement of financial instruments:

a) Financial assets: IFRS 9 classifies all financial assets that are currently in the scope of IAS 39 into two categories: amortized cost and fair value. Where assets are measured at fair value, gains and losses are either recognized entirely in profit or loss (fair value through profit or loss, “FVTPL”), or recognized in other comprehensive income (fair value through other comprehensive income, “FVTOCI”). The new guidance has no significant impact on the classification and measurement of the financial assets of the Company as the vast majority of financial assets (except for derivatives) are currently measured at amortized cost, and meet the conditions for classification at amortized cost under IFRS 9. As a result, the Company maintained this classification.

b) Financial liabilities: IFRS 9 does not change the basic accounting model for financial liabilities under IAS 39. Two measurement categories continue to exist: FVTPL and amortized cost. Financial liabilities held for trading are measured at FVTPL, and all other financial liabilities are measured at amortized cost unless the fair value option is applied. As a result, the Company concluded that there is no significant impact on the consolidated financial statements.

The new impairment model requires the recognition of impairment provisions based on expected credit losses (“ECL”) rather than only incurred credit losses as is the case under IAS 39. The Company reviewed its portfolio of financial assets subject to the new model of impairment under the new methodology (using credit default swaps, rating from credit agencies and other external inputs in order to estimate the probability of default), and recorded an adjustment to the opening balance sheet of these consolidated financial statements as detailed below in the table showing the adjustments arising from the application of IFRS 9.

F-18

The accounting for certain modifications and exchanges of financial liabilities measured at amortized cost (e.g. bank loans and issued bonds) changes on the transition from IAS 39 to IFRS 9. This change arises from a clarification by the IASB in the Basis for Conclusions of IFRS 9. Under IFRS 9 it is now clear that there can be an effect in the income statement for modification and exchanges of financial liabilities that are considered “non-substantial” (when the net present value of the cash flows, including any fees paid net of any fees received, is lower than 10% different from the net present value of the remaining cash flows of the liability prior to the modification, both discounted at the original effective interest rate). The Company reviewed retrospectively these transactions and recorded an adjustment to the opening balance sheet of these consolidated financial statements as detailed below in the table showing the adjustments arising from the application of IFRS 9.

IFRS 9 also introduces changes in hedge accounting. The hedge accounting requirements in IFRS 9 are optional and tend to facilitate the use of hedge accounting by preparers of financial statements. As a result, the Company reviewed its portfolio of derivatives and recorded an adjustment to the opening balance sheet of these consolidated financial statements as detailed below in the table showing the adjustments arising from the application of IFRS 9.

The impact of applying IFRS 9 to the consolidated financial statements for the year ended December 31, 2018 is not significant.

IFRS 16 ‘Leases’

The IASB issued a new lease accounting standard, IFRS 16, in January 2016, which requires the recognition of lease contracts on the consolidated statement of financial position.

IFRS 16 eliminates the classification of leases as either operating leases or finance leases for a lessee. Instead all leases are treated in a similar way to finance leases applying IAS 17. Leases are ‘capitalized’ by recognizing the present value of the lease payments and showing them either as lease assets (right-of-use of assets) or together with contracted concessional assets. If lease payments are made over time, a company also recognizes a financial liability representing its obligation to make future lease payments.

In the income statement, IFRS 16 replaces the straight-line operating lease expense for those leases applying IAS 17, with a depreciation charge for the lease asset (included within operating expenses) and an interest expense on the lease liability (included within finance expenses). IFRS 16 also impacts the presentation of cash flows related to former off-balance sheet leases.

The Company performed its assessment of the impact on its consolidated financial statements. The most significant impact identified is that the Company recognizes new assets and liabilities for its existing operating leases of land rights, buildings, offices and equipment.

The standard is effective for annual periods beginning on or after January 1, 2019, with earlier application permitted for entities that apply IFRS 15 at or before the date of initial application of IFRS 16. The Company decided to early adopt the standard as of January 1, 2018.

An entity shall apply this standard using one of the following two methods: full retrospectively approach or a modified retrospective approach. The Company has chosen the latter and accounted for assets as an amount equal to liability at the date of initial application. The impact on the opening balance sheet of these consolidated financial statements is shown in the table below.

The impact of applying IFRS 16 to the consolidated financial statements for the year ended December 31, 2018 is not significant.

2.2. Principles to include and record companies in the consolidated financial statements

Companies included in these consolidated financial statements are accounted for as subsidiaries as long as Atlantica Yield has had control over them and are accounted for as investments under the equity method as long as Atlantica Yield has had significant influence over them, in the periods presented.

Controlled entities

Control is achieved when the Company:

Has power over the investee;

Is exposed, or has rights, to variable returns from its involvement with the investee; and

F-20

Has the ability to use its power to affect its returns.

The Company reassesses whether or not it controls an investee when facts and circumstances indicate that there are changes to one or more of the three elements of control listed above.

The Company uses the acquisition method to account for business combinations of companies controlled by a third party. According to this method, identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. Any contingent consideration is recognized at fair value at the acquisition date and subsequent changes in its fair value are recognized in accordance with IFRS 9 either in profit or loss or as a change to other comprehensive income. Acquisition related costs are expensed as incurred. The Company recognizes any non-controlling interest in the acquiree either at fair value or at the non-controlling interest’s proportionate share of the acquirer’s net assets on an acquisition by acquisition basis.

All assets and liabilities between entities of the group, equity, income, expenses, and cash flows relating to transactions between entities of the group are eliminated in full.

Investments accounted for under the equity method

An associate is an entity over which the Company has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies.

The results and assets and liabilities of associates are incorporated in these financial statements using the equity method of accounting. Under the equity method, an investment in an associate is initially recognized in the statement of financial position at cost and adjusted thereafter to recognize the Company share of the profit or loss and other comprehensive income of the associate.

Controlled entities and associates included in these financial statements as of December 31, 2018 and 2017 are set out in appendices.

2.3. Contracted concessional assets and price purchase agreements

Contracted concessional assets and price purchase agreements (PPAs) include fixed assets financed through project debt, related to service concession arrangements recorded in accordance with IFRIC 12, except for Palmucho, which is recorded in accordance with IAS 17 and PS10, PS20, Mini-Hydro, Chile TL 3 and Seville PV, which are recorded as tangible assets in accordance with IAS 16. The infrastructures accounted for by the Company as concessions are related to the activities concerning electric transmission lines, solar electricity generation plants, cogeneration plants, wind farms and water plants. The useful life of these assets is approximately the same as the length of the concession arrangement. The infrastructure used in a concession can be classified as an intangible asset or a financial asset, depending on the nature of the payment entitlements established in the agreement.

Under the terms of contractual arrangements within the scope of this interpretation, the operator shall recognize and measure revenue in accordance with IFRS 15 for the services it performs. If the operator performs more than one service (i.e. construction or upgrade services and operation services) under a single contract or arrangement, consideration received or receivable shall be allocated by reference to the relative fair values of the services delivered, when the amounts are separately identifiable.

Intangible asset

The Company recognizes an intangible asset to the extent that it receives a right to charge final customers for the use of the infrastructure. This intangible asset is subject to the provisions of IAS 38 and is amortized linearly, taking into account the estimated period of commercial operation of the infrastructure which coincides with the concession period.

F-21

Once the infrastructure is in operation, the treatment of income and expenses is as follows:

Operating and maintenance costs and general overheads and administrative costs are recorded in accordance with the nature of the cost incurred (amount due) in each period.

Financing costs are expensed as incurred.

Financial asset

The Company recognizes a financial asset when demand risk is assumed by the grantor, to the extent that the concession holder has an unconditional right to receive payments for the asset. This asset is recognized at the fair value of the construction services provided, considering upgrade services in accordance with IFRS 15, if any.

The financial asset is subsequently recorded at amortized cost calculated according to the effective interest method. Revenue from operations and maintenance services is recognized in each period according to IFRS 15 “Revenue from contracts with Customers”. The remuneration of managing and operating the asset resulting from the valuation at amortized cost is also recorded in revenue.

Financing costs are expensed as incurred.

According to IFRS 9, Atlantica recognises an allowance for expected credit losses (ECLs) for all debt instruments not held at fair value through profit or loss. ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that the Company expects to receive.

There are two main approaches to applying the ECL model according to IFRS 9: the general approach which involves a three stage approach, and the simplified approach, which can be applied to trade receivables, contract assets and lease receivables. Atlantica has elected to apply the simplified approach. Under this approach, there is no need to monitor for significant increases in credit risk and entities will be required to measure lifetime expected credit losses at each end of reporting period.

The key elements of the ECL calculations are the following:

the Probability of Default (“PD”) is an estimate of the likelihood of default over a given time horizon. Atlantica calculates PD based on Credit Default Swaps spreads (“CDS”);

the Exposure at Default (“EAD”) is an estimate of the exposure at a future default date;

the Loss Given Default (“LGD”) is an estimate of the loss arising in the case where a default occurs at a given time. It is based on the difference between the contractual cash flows due and those that the Company would expect to receive. It is expressed as a percentage of the EAD.

Property, plant and equipment

Property, plant and equipment includes property, plant and equipment of companies or project companies. Property, plant and equipment is measured at historical cost, including all expenses directly attributable to the acquisition, less depreciation and impairment losses, with the exception of land, which is presented net of any impairment losses.

Once the infrastructure is in operation, the treatment of income and expenses is the same as the one described above for intangible asset.

F-22

2.4. Borrowing costs

Interest costs incurred in the construction of any qualifying asset are capitalized over the period required to complete and prepare the asset for its intended use. A qualifying asset is an asset that necessarily takes a substantial period of time to get ready for its internal use or sale, which is considered to be more than one year. Remaining borrowing costs are expensed in the period in which they are incurred.

2.5 Asset impairment

Atlantica Yield reviews its contracted concessional assets to identify any indicators of impairment at least annually.

The recoverable amount of an asset is the higher of its fair value less costs to sell and its value in use, defined as the present value of the estimated future cash flows to be generated by the asset. In the event that the asset does not generate cash flows independently of other assets, the Company calculates the recoverable amount of the Cash Generating Unit (‘CGU’) to which the asset belongs.

When the carrying amount of the CGU to which these assets belong is higher than its recoverable amount, the assets are impaired.

Assumptions used to calculate value in use include a discount rate, growth rate and projections considering real data based in the contracts terms and projected changes in both selling prices and costs. The discount rate is estimated by Management, to reflect both changes in the value of money over time and the risks associated with the specific CGU.

For contracted concessional assets, with a defined useful life and with a specific financial structure, cash flow projections until the end of the project are considered and no terminal value is assumed.

Contracted concessional assets have a contractual structure that permits the Company to estimate quite accurately the costs of the project (both in the construction and in the operations periods) and revenue during the life of the project.

Projections take into account real data based on the contract terms and fundamental assumptions based on specific reports prepared internally and supported by specialists, assumptions on demand and assumptions on production. Additionally, assumptions on macro-economic conditions are taken into account, such as inflation rates, future interest rates, etc. and sensitivity analyses are performed over all major assumptions which can have a significant impact in the value of the asset.

Taking into account that in most CGUs the specific financial structure is linked to the financial structure of the projects that are part of those CGUs, the discount rate used to calculate the present value of cash-flow projections is based on the weighted average cost of capital (WACC) for the type of asset, adjusted, if necessary, in accordance with the business of the specific activity and with the risk associated with the country where the project is performed.

In any case, sensitivity analyses are performed, especially in relation with the discount rate used and fair value changes in the main business variables, in order to ensure that possible changes in the estimates of these items do not impact the possible recovery of recognized assets.

Accordingly, the following table provides a summary of the discount rates used (WACC) and growth rates to calculate the recoverable amount for CGUs with the operating segment to which it pertains:

Operating segment	Discount rate			Growth rate
EMEA		4% - 6	%		0	%
North America		5% - 6	%		0	%
South America		5% - 7	%		0	%

In the event that the recoverable amount of an asset is lower than its carrying amount, an impairment charge for the difference would be recorded in the income statement under the item “Depreciation, amortization and impairment charges”.

F-23

Pursuant to IAS 36, an impairment loss is recognized if the carrying amount of these assets exceeds the present value of future cash flows discounted at the initial effective interest rate.

2.6 Loans and accounts receivable

Loans and accounts receivable are non-derivative financial assets with fixed or determinable payments, not listed on an active market.

In accordance with IFRIC 12, certain assets under concessions qualify as financial assets and are recorded as is described in Note 2.3.

Pursuant to IAS 36, an impairment loss is recognized if the carrying amount of these assets exceeds the present value of future cash flows discounted at the initial effective interest rate.

Loans and accounts receivable are initially recognized at fair value plus transaction costs and are subsequently measured at amortized cost in accordance with the effective interest rate method. Interest calculated using the effective interest rate method is recognized under other financial income within financial income.

2.7. Derivative financial instruments and hedging activities

Derivatives are recorded at fair value. The Company applies hedge accounting to all hedging derivatives that qualify to be accounted for as hedges under IFRS-IASB.

Atlantica Yield applies cash flow hedging. Under this method, the effective portion of changes in fair value of derivatives designated as cash flow hedges are recorded temporarily in equity and are subsequently reclassified from equity to profit or loss in the same period or periods during which the hedged item affects profit or loss. Any ineffective portion of the hedged transaction is recorded in the consolidated income statement as it occurs.

2.8. Fair value estimates

Financial instruments measured at fair value are presented in accordance with the following level classification based on the nature of the inputs used for the calculation of fair value:

Level 1: Inputs are quoted prices in active markets for identical assets or liabilities.

Level 2: Fair value is measured based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices).

Level 3: Fair value is measured based on unobservable inputs for the asset or liability.

F-24

In the event that prices cannot be observed, the management shall make its best estimate of the price that the market would otherwise establish based on proprietary internal models which, in the majority of cases, use data based on observable market parameters as significant inputs (Level 2) but occasionally use market data that is not observed as significant inputs (Level 3). Different techniques can be used to make this estimate, including extrapolation of observable market data. The best indication of the initial fair value of a financial instrument is the price of the transaction, except when the value of the instrument can be obtained from other transactions carried out in the market with the same or similar instruments, or valued using a valuation technique in which the variables used only include observable market data, mainly interest rates. Differences between the transaction price and the fair value based on valuation techniques that use data that is not observed in the market, are not initially recognized in the income statement.

Atlantica Yield derivatives correspond primarily to the interest rate swaps designated as cash flow hedges, which are classified as Level 2.

Description of the valuation method

Interest rate swap valuations are made by valuing the swap part of the contract and valuing the credit risk. The methodology used by the market and applied by Atlantica Yield to value interest rate swaps is to discount the expected future cash flows according to the parameters of the contract. Variable interest rates, which are needed to estimate future cash flows, are calculated using the curve for the corresponding currency and extracting the implicit rates for each of the reference dates in the contract. These estimated flows are discounted with the swap zero curve for the reference period of the contract.

The effect of the credit risk on the valuation of the interest rate swaps depends on the future settlement. If the settlement is favorable for the Company, the counterparty credit spread will be incorporated to quantify the probability of default at maturity. If the expected settlement is negative for the Company, its own credit risk will be applied to the final settlement.

Classic models for valuing interest rate swaps use deterministic valuation of the future of variable rates, based on future outlooks. When quantifying credit risk, this model is limited by considering only the risk for the current paying party, ignoring the fact that the derivative could change sign at maturity. A payer and receiver swaption model is proposed for these cases. This enables the associated risk in each swap position to be reflected. Thus, the model shows each agent’s exposure, on each payment date, as the value of entering into the ‘tail’ of the swap, i.e. the live part of the swap.

Variables (Inputs)

Interest rate derivative valuation models use the corresponding interest rate curves for the relevant currency and underlying reference in order to estimate the future cash flows and to discount them. Market prices for deposits, futures contracts and interest rate swaps are used to construct these curves. Interest rate options (caps and floors) also use the volatility of the reference interest rate curve.

To estimate the credit risk of the counterparty, the credit default swap (CDS) spreads curve is obtained in the market for important individual issuers. For less liquid issuers, the spreads curve is estimated using comparable CDSs or based on the country curve. To estimate proprietary credit risk, prices of debt issues in the market and CDSs for the sector and geographic location are used.

The fair value of the financial instruments that results from the aforementioned internal models takes into account, among other factors, the terms and conditions of the contracts and observable market data, such as interest rates, credit risk and volatility. The valuation models do not include significant levels of subjectivity, since these methodologies can be adjusted and calibrated, as appropriate, using the internal calculation of fair value and subsequently compared to the corresponding actively traded price. However, valuation adjustments may be necessary when the listed market prices are not available for comparison purposes.

F-25

2.9. Clients and other receivables

Clients and other receivables are amounts due from customers for sales in the normal course of business. They are recognized initially at fair value and subsequently measured at amortized cost using the effective interest rate method, less allowance for doubtful accounts. Trade receivables due in less than one year are carried at their face value at both initial recognition and subsequent measurement, provided that the effect of not discounting flows is not significant.

An allowance for doubtful accounts is recorded when there is objective evidence that the Company will not be able to recover all amounts due as per the original terms of the receivables.

2.10. Cash and cash equivalents

Cash and cash equivalents include cash in hand, cash in bank and other highly-liquid current investments with an original maturity of three months or less which are held for the purpose of meeting short-term cash commitments.

2.11. Grants

Grants are recognized at fair value when it is considered that there is a reasonable assurance that the grant will be received and that the necessary qualifying conditions, as agreed with the entity assigning the grant, will be adequately complied with.

Grants are recorded as liabilities in the consolidated statement of financial position and are recognized in “Other operating income” in the consolidated income statement based on the period necessary to match them with the costs they intend to compensate.

In addition, as described in Note 2.12 below, grants correspond also to loans with interest rates below market rates, for the initial difference between the fair value of the loan and the proceeds received.

2.12. Loans and borrowings

Loans and borrowings are initially recognized at fair value, net of transaction costs incurred. Borrowings are subsequently measured at amortized cost and any difference between the proceeds initially received (net of transaction costs incurred in obtaining such proceeds) and the repayment value is recognized in the consolidated income statement over the duration of the borrowing using the effective interest rate method.

Loans with interest rates below market rates are initially recognized at fair value in liabilities and the difference between proceeds received from the loan and its fair value is initially recorded within “Grants and Other liabilities” in the consolidated statement of financial position, and subsequently recorded in “Other operating income” in the consolidated income statement when the costs financed with the loan are expensed.

2.13. Bonds and notes

The Company initially recognizes ordinary notes at fair value, net of issuance costs incurred. Subsequently, notes are measured at amortized cost until settlement upon maturity. Any other difference between the proceeds obtained (net of transaction costs) and the redemption value is recognized in the consolidated income statement over the term of the debt using the effective interest rate method.

2.14. Income taxes

Current income tax expense is calculated on the basis of the tax laws in force as of the date of the consolidated statement of financial position in the countries in which the subsidiaries and associates operate and generate taxable income.

Deferred income tax is calculated in accordance with the liability method, based upon the temporary differences arising between the carrying amount of assets and liabilities and their tax base. Deferred income tax is determined using tax rates and regulations which are expected to apply at the time when the deferred tax is realized.

F-26

Deferred tax assets are recognized only when it is probable that sufficient future taxable profit will be available to use deferred tax assets.

2.15. Trade payables and other liabilities

Trade payables are obligations arising from purchases of goods and services in the ordinary course of business and are recognized initially at fair value and are subsequently measured at their amortized cost using the effective interest method. Other liabilities are obligations not arising in the normal course of business and which are not treated as financing transactions. Advances received from customers are recognized as “Trade payables and other current liabilities”.

2.16. Foreign currency transactions

The consolidated financial statements are presented in U.S. dollars, which is Atlantica Yield functional and reporting currency. Financial statements of each subsidiary within the Company are measured in the currency of the principal economic environment in which the subsidiary operates, which is the subsidiary’s functional currency.

Transactions denominated in a currency different from the subsidiary’s functional currency are translated into the subsidiary’s functional currency applying the exchange rates in force at the time of the transactions. Foreign currency gains and losses that result from the settlement of these transactions and the translation of monetary assets and liabilities denominated in foreign currency at the year-end rates are recognized in the consolidated income statement, unless they are deferred in equity, as occurs with cash flow hedges and net investment in foreign operations hedges.

Assets and liabilities of subsidiaries with a functional currency different from the Company’s reporting currency are translated to U.S. dollars at the exchange rate in force at the closing date of the financial statements. Income and expenses are translated into U.S. dollars using the average annual exchange rate, which does not differ significantly from using the exchange rates of the dates of each transaction. The difference between equity translated at the historical exchange rate and the net financial position that results from translating the assets and liabilities at the closing rate is recorded in equity under the heading “Accumulated currency translation differences”.

Results of companies carried under the equity method are translated at the average annual exchange rate.

2.17. Equity

The Company has recyclable balances in its equity, corresponding mainly to hedge reserves and translation differences arising from currency conversion in the preparation of these consolidated financial statements. These balances have been presented separately in Equity.

Non-controlling interest represents interest from other partners in entities included in these consolidated financial statements which are not fully owned by Atlantica Yield as of the dates presented.

Parent company reserves together with the Share capital represent the Parent’s net investment in the entities included in these consolidated financial statements.

2.18. Provisions and contingencies

Provisions are recognized when:

there is a present obligation, either legal or constructive, as a result of past events;

it is more likely than not that there will be a future outflow of resources to settle the obligation; and

the amount has been reliably estimated.

Provisions are initially measured at the present value of the expected outflows required to settle the obligation and subsequently valued at amortized cost following the effective interest method. The balance of Provisions disclosed in the Notes reflects management’s best estimate of the potential exposure as of the date of preparation of the consolidated financial statements.

F-27

Contingent liabilities are possible obligations, existing obligations with low probability of a future outflow of economic resources and existing obligations where the future outflow cannot be reliably estimated. Contingences are not recognized in the consolidated statements of financial position unless they have been acquired in a business combination.

Some companies included in the group have dismantling provisions, which are intended to cover future expenditures related to the dismantlement of the plants and it will be likely to be settled with an outflow of resources in the long term (over 5 years).

Such provisions are accrued when the obligation for dismantling, removing and restoring the site on which the plant is located, is incurred, which is usually during the construction period. The provision is measured in accordance with IAS 37, “Provisions, Contingent Liabilities and Contingent Assets” and is recorded as a liability under the heading “Grants and other liabilities” of the Financial Statements, and as part of the cost of the plant under the heading “Contracted concessional assets.”

2.19. Use of estimates

Some of the accounting policies applied require the application of significant judgment by management to select the appropriate assumptions to determine these estimates. These assumptions and estimates are based on the historical experience, advice from experienced consultants, forecasts and other circumstances and expectations as of the close of the financial period. The assessment is considered in relation to the global economic situation of the industries and regions where the Company operates, taking into account future development of the businesses of the Company. By their nature, these judgments are subject to an inherent degree of uncertainty; therefore, actual results could materially differ from the estimates and assumptions used. In such cases, the carrying values of assets and liabilities are adjusted.

The most critical accounting policies, which reflect significant management estimates and judgment to determine amounts in these consolidated financial statements, are as follows:

Contracted concessional agreements and PPAs.

Impairment of intangible assets and property, plant and equipment.

Assessment of control.

Derivative financial instruments and fair value estimates.

Income taxes and recoverable amount of deferred tax assets.

As of the date of preparation of these consolidated financial statements, no relevant changes in the estimates made are anticipated and, therefore, no significant changes in the value of the assets and liabilities recognized at December 31, 2018, are expected.

Note 3.- Financial risk management

Atlantica Yield’s activities are exposed to various financial risks: market risk (including currency risk and interest rate risk), credit risk and liquidity risk. Risk is managed by the Company’s Risk Finance and Compliance Departments, which are responsible for identifying and evaluating financial risks quantifying them by project, region and company, in accordance with mandatory internal management rules. Written internal policies exist for global risk management, as well as for specific areas of risk. In addition, there are official written management regulations regarding key controls and control procedures for each company and the implementation of these controls is monitored through internal audit procedures.

F-28

Market risk

The Company is exposed to market risk, such as movement in foreign exchange rates and interest rates. All of these market risks arise in the normal course of business and the Company does not carry out speculative operations. For the purpose of managing these risks, the Company uses a series of interest rate swaps and options, and currency options. None of the derivative contracts signed has an unlimited loss exposure.

Interest rate risk

Interest rate risk arises when the Company’s activities are exposed to changes in interest rates, which arises from financial liabilities at variable interest rates. The main interest rate exposure for the Company relates to the variable interest rate with reference to the Libor and Euribor. To minimize the interest rate risk, the Company primarily uses interest rate swaps and interest rate options (caps), which, in exchange for a fee, offer protection against an increase in interest rates. The Company does not use derivatives for speculative purposes.

As a result, the notional amounts hedged, strikes contracted and maturities, depending on the characteristics of the debt on which the interest rate risk is being hedged, are very diverse, including the following:

Project debt in Euros: the Company hedges between 81% and 100% of the notional amount, maturities until 2030 and average guaranteed interest rates of between 0.60% and 4.87%.

Project debt in U.S. dollars: the Company hedges between 70% and 100% of the notional amount, including maturities until 2034 and average guaranteed interest rates of between 2.32% and 5.27%.

In connection with the interest rate derivative positions of the Company, the most significant impacts on these consolidated financial statements are derived from the changes in EURIBOR or LIBOR, which represent the reference interest rate for the majority of the debt of the Company. In the event that Euribor and Libor had risen by 25 basis points as of December 31, 2018, with the rest of the variables remaining constant, the effect in the consolidated income statement would have been a loss of $2,731 thousand (a loss of $1,066 thousand in 2017 and a loss of $2,563 thousand in 2016) and an increase in hedging reserves of $32,928 thousand ($39,142 thousand in 2017 and $37,290 thousand in 2016). The increase in hedging reserves would be mainly due to an increase in the fair value of interest rate swaps designated as hedges.

A breakdown of the interest rates derivatives as of December 31, 2018 and 2017, is provided in Note 9.

Currency risk

The main cash flows in the entities included in these consolidated financial statements are cash collections arising from long-term contracts with clients and debt payments arising from project finance repayment. Given that financing of the projects is always closed in the same currency in which the contract with client is signed, a natural hedge exists for the main operations of the Company.

In addition, the Company policy is to contract currency options with leading financial institutions, which guarantee a minimum Euro-U.S. dollar exchange rate on the net distributions expected from Spanish solar assets. The net Euro exposure is 100% covered for the coming 12 months and 75% for the following 12 months on a rolling basis.

Credit risk

The Company considers that it has a limited credit risk with clients as revenues derive from power purchase agreements with electric utilities and state-owned entities. The Company has investment grade offtakers in all the assets except for Quadra 1&2, ATN2, Skikda and Honaine, which represent a low percentage of the cash available for distribution on a run-rate basis. In the case of Kaxu, the offtaker has a counter-guarantee from the Republic of South Africa.

F-29

Liquidity risk

Atlantica Yield’s liquidity and financing policy is intended to ensure that the Company maintains sufficient funds to meet our financial obligations as they fall due.

Project finance borrowing permits the Company to finance the project through project debt and thereby insulate the rest of its assets from such credit exposure. The Company incurs in project-finance debt on a project-by-project basis.

Note 4.- Financial information by segment

Atlantica Yield’s segment structure reflects how management currently makes financial decisions and allocates resources. Its operating and reportable segments are based on the following geographies where the contracted concessional assets are located:

North America

South America

EMEA

Based on the type of business, as of December 31, 2018 the Company had the following business sectors:

Renewable energy: Renewable energy assets include two solar plants in the United States, Solana and Mojave, each with a gross capacity of 280 MW and located in Arizona and California, respectively. The Company owns eight solar platforms in Spain: Solacor 1 and 2 with a gross capacity of 100 MW, PS10 and PS20 with a gross capacity of 31 MW, Solaben 2 and 3 with a gross capacity of 100 MW, Helioenergy 1 and 2 with a gross capacity of 100 MW, Helios 1 and 2 with a gross capacity of 100 MW, Solnova 1, 3 and 4 with a gross capacity of 150 MW, Solaben 1 and 6 with a gross capacity of 100 MW and Seville PV with a gross capacity of 1 MW. The Company also owns a solar plant in South Africa, Kaxu with a gross capacity of 100 MW. Additionally, the Company owns three wind farms in Uruguay, Palmatir, Cadonal and Melowind, with a gross capacity of 50 MW each, and a hydroelectric power plant in Peru with a gross capacity of 4MW.

Efficient natural gas: The Company´s sole efficient natural gas asset is ACT, a 300 MW cogeneration plant in Mexico, which is party to a 20-year take-or-pay contract with Pemex for the sale of electric power and steam.

Electric transmission lines : Electric transmission assets include (i) three lines in Peru, ATN, ATS and ATN2, spanning a total of 1,015 miles; and (ii) four lines in Chile, Quadra 1, Quadra 2, Palmucho and Chile TL3, spanning a total of 137 miles.

Water: Water assets include a minority interest in two desalination plants in Algeria, Honaine and Skikda with an aggregate capacity of 10.5 M ft ³ per day.

Atlantica Yield’s Chief Operating Decision Maker (CODM) assesses the performance and assignment of resources according to the identified operating segments. The CODM considers the revenues as a measure of the business activity and the Further Adjusted EBITDA as a measure of the performance of each segment. Further Adjusted EBITDA is calculated as profit/(loss) for the period attributable to the parent company, after adding back loss/(profit) attributable to non-controlling interests from continued operations, income tax, share of profit/(loss) of associates carried under the equity method, finance expense net, depreciation, amortization and impairment charges of entities included in these consolidated financial statements, and compensations received from Abengoa in lieu of ACBH dividends (for the years 2017 and 2016 only).

F-30

In order to assess performance of the business, the CODM receives reports of each reportable segment using revenues and Further Adjusted EBITDA. Net interest expense evolution is assessed on a consolidated basis. Financial expense and amortization are not taken into consideration by the CODM for the allocation of resources.

In the year ended December 31, 2018 Atlantica Yield had four customers with revenues representing more than 10% of the total revenues, i.e., three in the renewable energy and one in the efficient natural gas business sectors, and in the year ended December 31, 2017, had three customers with revenues representing more than 10% of the total revenues, i.e., two in the renewable energy and one in the efficient natural gas business sectors.

The following tables show Revenues and Further Adjusted EBITDA by operating segments and business sectors for the years 2018, 2017 and 2016:

Impact of changes in the scope in the consolidated financial statements

The amount of assets and liabilities integrated at the effective acquisition date for the aggregated change in scope is shown in the following table:

	Asset Acquisition for the year ended December 31, 2018
Concessional assets (Note 6)		155,909
Investments carried under the equity method (Note 7)		1
Current assets		5,646
Project debt long term (Note 15)		(79,016	)
Deferred tax liabilities (Note 18)		(590	)
Project debt short term (Note 15)		(2,346	)
Other current and non-current liabilities		(3,000	)
Asset acquisition - purchase price		(76,604	)
Net result of the asset acquisition		-

As a result of the acquisitions being made effective near to year end, the allocation of the purchase prices is provisional as of December 31, 2018. As such, the amounts indicated may be adjusted during the measurement period to reflect new information obtained about facts and circumstances that existed at the acquisition date that, if known, would have affected the amounts recognized as of December 31, 2018. The measurement period will not exceed one year from the acquisition dates.

The amount of revenue contributed by the acquisitions performed during 2018 to the consolidated financial statements of the Company for the year 2018 is $1.8 million, and the amount of loss after tax is $0.3 million. Had the acquisitions been consolidated from January 1, 2018, the consolidated statement of comprehensive income would have included additional revenue of $13.3 million and additional loss after tax of $0.7 million.

For the year ended December 31, 2017

There is no change in the scope of the consolidated financial statement in the year 2017.

Note 6.- Contracted concessional assets

Contracted concessional assets include fixed assets financed through project debt, related to service concession arrangements recorded in accordance with IFRIC 12, except for Palmucho, which is recorded in accordance with IAS 17, and PS10, PS20, Seville PV, Mini-Hydro and Chile TL3 which are recorded as property plant and equipment in accordance with IAS 16. Concessional assets recorded in accordance with IFRIC 12 are either intangible of financial assets. As of December 31, 2018, contracted concessional financial assets amount to $843,291 thousand ($936,004 thousand as of December 31, 2017).

For further details on the application of IFRIC 12 to projects, see Appendix III.

The following table shows the movements of contracted concessional assets included in the heading “Contracted Concessional assets” for 2018:

Cost

Total as of January 1, 2018	10,633,769
Additions	10,463
Application of IFRS 16 – Leases (Note 2)	62,982
Subtractions	(92,814	)
Change in the scope of the consolidated financial statements (Note 5)	170,040
Translation differences	(280,680	)

Total as of December 31, 2018	10,475,828

F-37

Accumulated amortization

Total as of January 1, 2018	(1,549,499	)
Adjustments arising from application of IFRS9 - Expected Credit Losses (Note 2)	(53,048	)
Additions	(362,697	)
Change in the scope of the consolidated financial statements (Note 5)	(14,131	)
Translation differences	52,728
Total accum. amort. as of December 31, 2018	(1,926,647	)
Net balance at December 31, 2018	8,549,181

During 2018, contracted concessional assets decreased primarily due to the effect of the depreciation of the Euro against the U.S. dollar for the year ended December 31, 2018 compared to the year ended December 31, 2017 and to the amortization charge for the year.

Other relevant movements in the cost of contracted concessional assets are an increase for the acquisition of new concessional assets (see Note 5), the impact of the application of IFRS 16, ´Leases´ from January 1, 2018 (see Note 2), partially offset by a decrease for the payments received from Abengoa by Solana in March and December 2018 further to Abengoa´s obligation as EPC Contractor (see Note 10).

Amortization and impairment amount includes the recognition of impairment provisions based on expected credit losses due to the application of IFRS 9, ´Financial instruments´ from January 1, 2018 (see Note 2).

The decrease included in “Reclassification and other movements” is mainly due to the reclassification from the long to the short term of the current portion of the contracted concessional financial assets.

Considering the lower production compared with the run-rate production expected for Solana due to the technical issues experienced since COD in the asset and the uncertainty around level of production in the future, the Company identified a triggering event of impairment during the year 2018 in compliance with IAS 36, Impairment of Assets. As a result, an impairment test has been performed resulting in the recording of an impairment loss of $42,721 thousand as of December 31, 2018.

An adverse change in the key assumptions which are individually used for the valuation could lead to future impairment recognition; specifically, a 5% decrease in generation over the entire remaining useful life (PPA) of the project would generate an additional impairment of approximately $72 million. An increase of 50 basis points in the discount rate would lead to an additional impairment of approximately $50 million.

In addition, the Company identified a triggering event of impairment for Mojave as a result of the negative credit outlooks of Pacific Gas and Electric Company, the offtaker of the plant, as of December 31, 2018 (see Note 23.2 for further details). This project is within the Renewable energy sector and North America geography. The Company therefore performed an impairment test as of December 31, 2018, which resulted in the recoverable amount (value in use) exceeding the carrying amount of the asset by 10%. To determine the value in use of the asset, a specific discount rate has been used in each year considering changes in the debt/equity leverage ratio over the useful life of this project, resulting in the use of a range of discount rates between 4.6% and 5.8%.

F-38

The following table shows the movements of contracted concessional assets included in the heading “Contracted Concessional assets” for 2017:

Cost

Total as of January 1, 2017	10,067,596
Additions	15,426
Subtractions	(42,500	)
Translation differences	593,247
Total as of December 31, 2017	10,633,769

Accumulated amortization

Total as of January 1, 2017	(1,143,324	)
Additions	(309,846	)
Translation differences	(96,329	)
Total accum. amort. as of December 31, 2017	(1,549,499	)
Net balance at December 31, 2017	9,084,270

During 2017 contracted concessional assets increased primarily due to the effect of appreciation of the Euro against the U.S. dollar for the year ended December 31, 2017 compared to the year ended December 31, 2016, this effect has been partially compensated by the amortization charge for the year.

The decrease relates to the indemnity received from Abengoa by Solana in December 2017 further to Abengoa´s obligation as EPC Contractor (see Note 10).

No losses from impairment of contracted concessional assets were recorded during the year ended December 31, 2017.

F-41

The derivatives are primarily interest rate cash-flow hedges. All are classified as non-current assets or non-current liabilities, as they hedge long-term financing agreements.

Additionally, the Company owns currency options with leading international financial institutions, which guarantee minimum Euro-U.S. dollar exchange rates. The strategy of the Company is to hedge the exchange rate for the distributions from its Spanish assets after deducting euro-denominated interest payments and euro-denominated general and administrative expenses. Through currency options, the strategy of the Company is to hedge 100% of its euro-denominated net exposure for the next 12 months and 75% of its euro denominated net exposure for the following 12 months, on a rolling basis.

As stated in Note 3 to these consolidated financial statements, the general policy is to hedge variable interest rates of financing agreements purchasing call options (caps) in exchange of a premium to fix the maximum interest rate cost and contracting floating to fixed interest rate swaps.

As a result, the notional amounts hedged, strikes contracted and maturities, depending on the characteristics of the debt on which the interest rate risk is being hedged, can be diverse:

·	Project debt in Euros: the Company hedges between 81% and 100% of the notional amount, maturities until 2030 and average guaranteed interest rates of between 0.60% and 4.87%.

·	Project debt in U.S. dollars: the Company hedges between 70% and 100% of the notional amount, including maturities until 2034 and average guaranteed interest rates of between 2.32% and 5.27%.

The table below shows a breakdown of the maturities of notional amounts of derivatives designated as cash flow hedges as of December 31, 2018 and 2017.

Notionals	Balance as of December 31, 2018				Balance as of December 31, 2017
	Cap		Swap		Cap		Swap
Up to 1 year		42,846		93,440		42,324		139,939
Between 1 and 2 years		45,603		119,568		45,422		94,285
Between 2 and 3 years		48,774		234,572		48,215		103,536
Subsequent years		535,774		1,858,061		620,378		1,893,850
Total	$	672,997	$	2,305,641	$	756,339	$	2,231,611

The table below shows a breakdown of the maturity of the fair values of derivatives designated as cash flow hedges as of December 31, 2018 and 2017. The net position of the fair value of caps and swaps for each year end reconciles with the net position of derivative assets and derivative liabilities in the consolidated statement of financial position:

Fair value	Balance as of December 31, 2018					Balance as of December 31, 2017
	Cap		Swap			Cap		Swap
Up to 1 year		493		(11,848	)		347		(13,224	)
Between 1 and 2 years		2,172		(13,231	)		978		(14,378	)
Between 2 and 3 years		562		(15,151	)		396		(15,923	)
Subsequent years		8,344		(238,922	)		6,509		(286,206	)
Total	$	11,571		(279,152	)	$	8,230		(329,731	)

During 2018, fair value of derivatives increased mainly due to an increase in the fair value of interest rate cash-flow hedges resulting from the increase in future interest rates.

The net amount of the fair value of interest rate derivatives designated as cash flow hedges transferred to the consolidated income statement in 2018 is a loss of $67,519 thousand (loss of $70,953 thousand in 2017 and a loss of $72,774 thousand in 2016). Additionally, the net amount of the time value component of the cash flow derivatives fair value recognized in the consolidated income statement for the year 2018, 2017 and 2016 has been a loss of $560 thousand, a loss of $860 thousand and a gain of $1,694 thousand respectively.

The after-tax result accumulated in equity in connection with derivatives designated as cash flow hedges at the years ended December 31, 2018 and 2017, amount to a $95,011 thousand gain and a $80,968 thousand gain respectively.

Note 10.- Related parties

During the normal course of business, the Company has historically conducted operations with related parties consisting mainly of Abengoa´s subsidiaries and non-controlling interests. The transactions were completed at market rates.

Further to the sale of its remaining 16.47% stake in the Company to Algonquin on November 27, 2018, Abengoa ceased to fulfill the conditions to be a related party as per IAS 24 - Related Parties Disclosures. Algonquin on its side is a related party since it completed the acquisition of a 25% stake in the Company in March 2018.

Details of balances with related parties as of December 31, 2018 and 2017 are as follows:

	Balance as of December 31,
	2018		2017

Credit receivables (current)		5,328		11,567

Credit payables (non-current)		33,675		141,031
Total non-current payables with related parties		33,675		141,031

Receivables and payables as of December 31, 2018 fully relate to debts with non-controlling interests partners in Kaxu, Solaben 2&3 and Solacor 1&2.

Payables to related parties as of December 31, 2017 included mainly payables to Abengoa, mainly for Operation and Maintenance services. The operation and maintenance services received in some of the Spanish solar assets of the Company include a variable portion payable in the long term. On April 26, 2018, Atlantica Yield plc purchased from Abengoa the long-term operation and maintenance payable accrued for the period up to December 31, 2017, which was recorded for an amount of $57.3 million at the date of repayment. The Company paid $18.3 million for this extinguishment of debt and accounted for the difference of $39.0 million with the carrying amount of the debt as an income in the profit and loss statement.

Total payables to Abengoa as of December 31, 2018 amount to $35.3 million, primarily made up of Operation and Maintenance services, but are not considered as related party balance anymore.

The transactions carried out by entities included in these consolidated financial statements with related parties not included in the consolidation perimeter of Atlantica Yield, primarily with Abengoa and with subsidiaries of Abengoa, during the twelve-month periods for the years ended December 31, 2018, 2017 and 2016 have been as follows:

	For the twelve-month period ended December 31,
	2018			2017			2016
Services rendered		-			3,495			1,220
Services received		(101,582	)		(114,416	)		(115,779	)
Financial income		3,721			74			60
Financial expenses		(398	)		(1,154	)		(2,460	)

Services received primarily include operation and maintenance services received by some assets.

F-43

As of December 31, 2017, the figures detailed in the table above do not include the compensation received from Abengoa in lieu of dividends from ACBH for $10.4 million. As of December 31, 2016, the figures do not include the compensation received from Abengoa in lieu of dividends from ACBH for $28.0 million, income for the cancellation of the subordinated debt Solnova Electricidad S.A. owed to Abener for $7.6 million and income of $1.7 million for discounts received from Abengoa for the prepayment of payables.

F-44

In addition, Abengoa maintains a number of obligations under EPC, O&M and other contracts, as well as indemnities covering certain potential risks. Additionally, Abengoa represented that further to the accession to the restructuring agreement, Atlantica Yield would not be a guarantor of any obligation of Abengoa with respect to third parties and agreed to indemnify the Company for any penalty claimed by third parties resulting from any breach in such representations. The Company has contingent assets, which have not been recognized as of December 31, 2018, related to the obligations of Abengoa referred above, which result and amounts will depend on the occurrence of uncertain future events. In particular as of April 26, 2018 and November 27, 2018 Abengoa agreed to pay Atlantica certain amounts subject to conditions which are beyond the control of the Company.

In November 2017, in the context of the agreement reached between Abengoa and Algonquin for the initial acquisition by Algonquin of 25.0% of the shares of the Company and based on the obligations of Abengoa under an EPC contract, the DOE signed a consent in relation to the Solana and Mojave projects which reduced the minimum ownership required by Abengoa in the Company from 30.0% to 16.0%. Solana received an aggregate amount of $120 million in payments from Abengoa ($42.5 million in December 2017 and $77.5 million in March 2018). Of the received sums, $95 million was used to repay Solana project debt and $25 million was set aside to cover other Abengoa obligations. In addition, in November 2018 in the context of the DOE consent to allow Abengoa to sell entirely its stake in Atlantica Yield, Solana received $16.5 million, of which $9 million was used to repay project debt and $7.5 million were set aside to cover potential repairs and other Abengoa obligations. Additionally, the long-term payments schedule signed between Abengoa and Solana was amended to include $7.4 million payable semi-annually over 2 years and $10.3 million payable semi-annually over the subsequent 4 years, beginning in January 2019. Solana also received a parcel of land adjacent to the Solana site accounted for at a fair value of $7.3 million. Furthermore, Abengoa agreed to pay $13 million to fund a reserve account progressively in 2020 and 2021. If Abengoa were not to make these payments, the Company would need to make them and in return will reduce the future bonus payments to Abengoa under the operation and maintenance agreements in the corresponding amounts. The aforementioned amounts result of Abengoa’s obligations as EPC contractor. Likewise, in November 2018, and after satisfying all conditions precedent to completion, the DOE signed a consent in relation to the Solana and Mojave projects for the sale of the remaining Abengoa’s 16.47% interest in the Company to Algonquin. The share sale was completed on November 27, 2018. The main part of the aforementioned amounts are based on the EPC Contract guarantee for liquidated damages considering the average production during the first three years of ramp-up period of the plant which is a service-concession arrangement under IFRIC 12 (intangible asset). For these amounts, the Company reduced the value of the intangible asset since this amount was a variable consideration. In addition, the amortization of the plant is adjusted accordingly.

The Company entered into a Financial Support Agreement on June 13, 2014 under which Abengoa agreed to maintain any guarantees and letters of credit that have been provided by it on behalf of or for the benefit of Atlantica Yield and its affiliates for a period of five years. As of December 31, 2018, the aforementioned guarantees amounted to $23 million. In the context of that agreement, in July 2017, Atlantica replaced guarantees amounting to $112 million previously issued by Abengoa, out of which $55 million were canceled in June 2018.

On November 17, 2014, the Company issued the Senior Notes due 2019 in an aggregate principal amount of $255,000 thousand (the “2019 Notes”). The 2019 Notes accrue annual interest of 7.00% payable semi-annually beginning on May 15, 2015 until their maturity date.

On February 10, 2017, the Company issued Senior Notes due 2022, 2023, 2024 (the “Note Issuance Facility”), in an aggregate principal amount of €275,000 thousand. The 2022 to 2024 Notes accrue annual interest, equal to the sum of (i) EURIBOR plus (ii) 4.90%, as determined by the Agent. Interest on the Notes are payable in cash quarterly in arrears on each interest payment date. The Company pays interest to the holders of record on each interest payment date. The interest rate on the Note Issuance Facility is fully hedged by two interest rate swaps contracted with Jefferies Financial Services, Inc. with effective date March 31, 2017 and maturity date December 31, 2022, resulting in the Company paying a net fixed interest rate of 5.5% on the Note Issuance Facility. Changes in fair value of these interest rate swaps have been recorded in the consolidated income statement. The Note Issuance Facility is a € denominated liability for which the Company applies net investment hedge accounting. When converted to US$ at US$/€ closing exchange rate, it contributes to reduce the impact in translation difference reserves generated in the equity of these consolidated financial statements by the conversion of the net assets of the Spanish solar assets into US$.

On July 20, 2017, the Company signed a credit facility (the “2017 Credit Facility”) for up to €10 million, approximately $11.5 million, which is available in euros or U.S. dollars.

The credit facility had a maturity date in July 2018. It was renewed during the month of July 2018 and the new maturity date is July 20, 2019.

On May 10, 2018, the Company entered into a $215 million revolving credit facility (the “New Revolving Credit Facility”) with Royal Bank of Canada, as administrative agent and Royal Bank of Canada and Canadian Imperial Bank of Commerce, as issuers of letters of credit. Amounts drawn down accrue interest at a rate per year equal to (A) for Eurodollar rate loans, LIBOR plus a percentage determined by reference to the leverage ratio of the Company, ranging between 1.60% and 2.25% and (B) for base rate loans, the highest of (i) the rate per annum equal to the weighted average of the rates on overnight U.S. Federal funds transactions with members of the U.S. Federal Reserve System arranged by U.S. Federal funds brokers on such day plus ½ of 1.00%, (ii) the U.S. prime rate and (iii) LIBOR plus 1.00%, in any case, plus a percentage determined by reference to the leverage ratio of the Company, ranging between 0.60% and 1.00%. Letters of credit may be issued using up to $70 million of the Revolving Credit Facility. The maturity of the Revolving Credit Facility is December 31, 2021. As of December 31, 2018, the Company had drawn down an amount of $108 million (net of debt issuance costs). During the month of January 2019, the amount of the New Revolving Credit Facility has been increased from $215 million to $300 million.

Current Corporate debt corresponds mainly to the nominal and accrued interest of the 2019 Notes and to the nominal of the 2017 Credit Facility.

The repayment schedule for the Corporate debt at the end of 2018 is as follows:

	2019		2020		2021		2022		2023		Subsequent years		Total

Note 15.- Project debt

The main purpose of the Company is the long-term ownership and management of contracted concessional assets, such as renewable energy, efficient natural gas, electric transmission line and water assets, which are financed through project debt. This note shows the project debt linked to the contracted concessional assets included in Note 6 of these consolidated financial statements.

Project debt is generally used to finance contracted assets, exclusively using as guarantee the assets and cash flows of the company or group of companies carrying out the activities financed. In most of the cases, the assets and/or contracts are set up as guarantee to ensure the repayment of the related financing.

Compared with corporate debt, project debt has certain key advantages, including a greater leverage and a clearly defined risk profile.

The variations for 2018 and 2017 of project debt have been the following:

	Project debt - long term			Project debt - short term			Total
Balance as of December 31, 2017		5.228.917			246.291			5.475.208

Main variations in Project debt during the year 2018 are the result of:

A net decrease primarily due to the contractual payments of debt for the year and the partial repayment of Solana debt using the indemnity received from Abengoa during the year 2018 for $61.5 million (see Note 10). Interests accrued are offset by a similar amount of interests paid during the year;

The impact of the first application of IFRS 9, ´Financial instruments´ from January 1, 2018 (see Note 2);

The impact of the refinancing of the debts of Helios 1/2 and Helioenergy 1/2 on May 18, 2018 and June 26, 2018 respectively. The terms of the new debts are not substantially different from the original debts refinanced and therefore the exchange of debts instruments does not qualify for an extinguishment of the original debts under IFRS 9, ´Financial instruments´. When there is a refinancing with a non-substantial modification of the original debt, there is a gain or loss recorded in the income statement. This gain or loss is equal to the difference between the present value of the cash flows under the original terms of the former financing and the present value of the cash flows under the new financing, discounted both at the original effective interest rate. In this respect, the Company recorded a $36.6 million financial income in the profit and loss statement of the consolidated financial statements (see Note 21);

The acquisition of assets and the consolidation of its debt during the year (see Note 5).

The line “Increases” includes primarily accrued interests for the year.

Main variations in Project debt during the year 2017 are the result of:

Net decrease primarily due to repayment of debt, considering that interests accrued are offset by a similar amount of interests paid during the year. Decrease in long-term debt primarily relates to the partial repayment of Solana debt using the indemnity received from Abengoa in December 2017 for $42.5 million (see Note 10);

A reclassification of the entire debt of Kaxu and Cadonal projects from short term to long term during the year 2017 as a result of the waiver obtained for Kaxu in March 2017 and the completion of certain pending conditions for Cadonal in October 2017. In addition, in 2017, Kaxu’s debt coverage ratio did not reach the minimum threshold due to the technical problems that the plant experienced since the end of 2016. However, the lenders of the project finance agreement granted a waiver to the asset and therefore reclassification of the debt to short-term does not apply in this case.

The repayment schedule for Project debt in accordance with the financing arrangements, at the end of 2018 is as follows and is consistent with the projected cash flows of the related projects.

2019				2020		2021		2022		2023		Subsequent years		Total
Interest Repayment		Nominal repayment
	21,916		242,538		257,012		268,625		299,840		326,413		3,674,770		5,091,114

Current and non-current loans with credit entities include amounts in foreign currencies for a total of $2,464,352 thousand as of December 31, 2018 ($2,778,043 thousand as of December 31, 2017).

The following table details the movement in Project debt for the year 2018, split between cash and non-cash items:

		January 1, 2018				Cash Flow				Non-cash changes				December 31, 2018
Project debt			5,475,208				(579,598	)			195,504				5,091,114

The non-cash changes primarily relate to interests accrued and to currency translation differences.

F-50

The equivalent in U.S. dollars of the most significant foreign-currency-denominated debts held by the Company is as follows:

	Balance as of December 31,
Currency	2018		2017
Euro		2,049,892		2,286,771
Algerian Dinar		29,545		35,093
Rand		384,915		456,179
Total		2,464,352		2,778,043

All of the Company’s financing agreements have a carrying amount close to its fair value.

Note 16.- Grants and other liabilities

Grants and other liabilities as of December 31, 2018 and December 31, 2017 are as follows:

	Balance as of December 31,
	2018		2017
Grants		1,150,805		1,225,877
Other liabilities		507,321		410,183
Grant and other non-current liabilities		1,658,126		1,636,060

As of December 31, 2018, the amount recorded in Grants corresponds primarily to the ITC Grant awarded by the U.S. Department of the Treasury to Solana and Mojave for a total amount of $739 million ($771 million as of December 31, 2017), which was primarily used to fully repay the Solana and Mojave short-term tranche of the loan with the Federal Financing Bank. The amount recorded in Grants as a liability is progressively recorded as other income over the useful life of the asset.

The remaining balance of the “Grants” account corresponds to loans with interest rates below market rates for Solana and Mojave for a total amount of $410 million ($452 million as of December 31, 2017). Loans with the Federal Financing Bank guaranteed by the Department of Energy for these projects bear interest at a rate below market rates for these types of projects and terms. The difference between proceeds received from these loans and its fair value, is initially recorded as “Grants” in the consolidated statement of financial position, and subsequently recorded in “Other operating income” starting at the entry into operation of the plants. Total amount of income for these two types of grants for Solana and Mojave is $59.3 million and $59.6 million for the year ended December 31, 2018 and 2017, respectively.

Other liabilities mainly relate to the investment from Liberty Interactive Corporation (‘Liberty’) made on October 2, 2013 for an amount of $300 million. The investment was made in class A shares of Arizona Solar Holding, the holding of Solana Solar plant in the United States. Such investment was made in a tax equity partnership which permits the partners to have certain tax benefits such as accelerated depreciation and ITC. Liberty has the right to receive 61.20% of taxable losses and distributions until such time as Liberty reaches a certain rate of return, or the Flip Date, and 22.60% of taxable losses and distributions thereafter. Given the underperformance of the asset in the last years, there is uncertainty regarding the Flip Date, regarding when it will occur, if so. The Company expects potential cash distributions from Solana to go mostly or entirely to Liberty in the upcoming years.

According to the stipulations of IAS 32 and in spite of the fact that the investment of Liberty is in shares, it does not qualify as equity and has been classified as a liability as of December 31, 2018 and 2017. The liability is recorded in Grants and other liabilities for a total amount of $358 million ($352 million as of December 31, 2017) and its current portion is recorded in other current liabilities for the remaining amount (see Note 17). This liability has been initially valued at fair value, calculated as the present value of expected cash-flows during the useful life of the concession, and is then measured at amortized cost in accordance with the effective interest method, considering the most updated expected future cash-flows.

F-51

Additionally, other liabilities include $57 million of finance lease liabilities as of December 31, 2018, further to the application of IFRS 16, Leases from January 1, 2018 (see Note 2).

Note 17.- Trade payables and other current liabilities

Trade payable and other current liabilities as of December 31, 2018 and 2017 are as follows:

	Balance as of December 31,
Item	2018		2017
Trade accounts payables		109,430		107,662
Down payments from clients		6,289		6,466
-Liberty (see Note 16)		37,119		-
Other accounts payable		39,195		41,016
Total		192,033		155,144

Trade accounts payables mainly relate to the operating and maintenance of the plants.

Nominal values of Trade payables and other current liabilities are considered to approximately equal to fair values and the effect of discounting them is not significant.

Note 18.- Income Tax

All the companies included in the Company file income taxes according to the tax regulations in force in each country on an individual basis or under consolidation tax regulations.

The consolidated income tax has been calculated as an aggregation of income tax expenses/income of each individual company. In order to calculate the taxable income of the consolidated entities individually, the accounting result is adjusted for temporary and permanent differences, recording the corresponding deferred tax assets and liabilities. At each consolidated income statement date, a current tax asset or liability is recorded, representing income taxes currently refundable or payable. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial statement and income tax purposes, as determined under enacted tax laws and rates.

Income tax payable is the result of applying the applicable tax rate in force to each tax-paying entity, in accordance with the tax laws in force in the country in which the entity is registered. Additionally, tax deductions and credits are available to certain entities, primarily relating to inter-company trades and tax treaties between various countries to prevent double taxation.

As of December 31, 2018, and 2017, the analysis of deferred tax assets and deferred tax liabilities is as follows:

Deferred tax assets	Balance as of December 31,
Concept	2018		2017
Net tax credits for operating losses carryforwards		55,835		71,219
Temporary differences derivatives financial instruments		79,865		93,719
Other temporary differences		366		198
Total deferred tax assets		136,066		165,136

Most of the net tax credits for operating losses carryforwards corresponds to Peru, South Africa and solar plants in Spain as of December 31, 2018.

Temporary differences for derivatives financial instruments are mainly due to ACT ($13 million) and solar plants in Spain ($62 million).

F-52

In relation to tax loss carryforwards and deductions pending to be used recorded as deferred tax assets, the entities evaluate its recoverability projecting forecasted taxable income for the upcoming years and taking into account their tax planning strategy. Deferred tax liabilities reversals are also considered in these projections, as well as any limitation established by tax regulations in force in each tax jurisdiction.

Deferred tax liabilities	Balance as of December 31,
Concept	2018		2017
Temporary differences tax/book amortization		126,792		113,432
Other temporary differences tax/book value of contracted concessional assets		73,793		66,247
Other temporary differences		10,415		6,904
Total deferred tax liabilities		211,000		186,583

As of December 31, 2018 and 2017, temporary differences as a result of accelerated tax amortization resulted in a net deferred tax liability position. These are primarily due to Solana and Mojave ($55 million in 2018 and $63 million in 2017) and solar plants in Spain ($74 million in 2018 and $51 million in 2017).

In the year ended as of December 31, 2017 there was an impact on the U.S. entities as a result of the tax reform and U.S. Internal Revenue Code Section 382 described as follows:

In December 2017 a tax reform, the Tax Cuts and Jobs Act, was enacted in the U.S., consisting mainly in a decrease in the corporate tax rate from 35% to 21% effective 1st of January 2018. The Company therefore adjusted the deferred tax assets and liabilities of its U.S. entities using the new enacted corporate tax rate as of December 31, 2017, resulting in a loss of $19 million recorded in the consolidated income statement for the year ended December 31, 2017;

In addition, the U.S. Internal Revenue Code (“IRC”) Section 382 establishes an annual limitation on the use of U.S. Net Operating Losses (“NOLs”) as a result of an ownership change. An “ownership change” would occur if the direct and indirect “5-percent shareholders”, as defined under Section 382 of the IRC, collectively increased their ownership in the Company by more than 50 percentage points over a rolling three-year period. The Company experienced during 2017 an ownership change due to Abengoa´s restructuring and changes in its shareholders´s base. As a result, the U.S. NOLs carryforwards generated through the date of change are subject to an annual limitation under Section 382, which resulted in a derecognition of deferred tax assets previously recognized amounting to $96 million corresponding to an amount of $387 million of NOLs and also taking into consideration the newly enacted corporate tax rate of 21%. This loss has been recorded in the consolidated income statement for the year ended December 31, 2017.

Other temporary differences tax/book value of contracted concessional assets, which resulted in a net deferred tax liability position relate primarily to ACT in both years.

The movements in deferred tax assets and liabilities during the years ended December 31, 2018 and 2017 were as follows:

Deferred tax assets	Amount

The reconciliation between the theoretical income tax resulting from applying an average statutory tax rate to income/(loss) before income tax and the actual income tax expense recognized in the consolidated income statements for the years ended December 31, 2018, 2017 and 2016, are as follows:

	For the year ended December 31,
Concept	2018			2017			2016
Consolidated income / (loss) before taxes		97,928			14,950			3,333

U.S. Internal Revenue Code Section 382		-			(96,328	)		-
Other non-taxable income/(expense)		1,915			(3,092	)		2,143
Corporate income tax		(42,659	)		(119,837	)		(1,666	)

Permanent differences in 2018, 2017 and 2016 are mainly due to ACT (Mexico).

The main implications derived from the Tax Cuts and Jobs Act enacted in December 2017 in the U.S. entities are:

A reduction of the Federal income tax rate from 35% to 21%, effective since January 1, 2018. This measure will imply a reduction of the tax burden of the Company. The effect on the deferred tax assets and liabilities has resulted in a $19 million loss in the year 2017;

F-54

A limitation of the deduction for net interest expense of all businesses in the U.S. The new limitation is imposed on net interest expense that exceeds 30% of EBITDA from 2018 to 2021, and 30% of EBIT from 2022 onwards. Interests disallowed would be deducted in the future in the event that those limits are not exceeded. After having considered the impacts of Section 382 commented above, the Company does not expect significant negative effects from this net interest expense limitation;

NOLs arising in tax years beginning after 2017 would be limited to 80% of taxable income. For new NOLs recognized after 2017, an indefinite carryforward would be allowed. The limitation of 80% is not applicable for NOLs generated before 2018. For existing NOLs before 2018, a carryforward of 20 years is still applicable. The new limitation does not trigger adverse tax effects to the U.S. subsidiaries of the Company considering the amount of NOLs to be generated in upcoming years and the projected amount of taxable income of these entities after having considered the impacts of Section 382;

Base erosion anti-abuse tax (BEAT): The BEAT applies to certain U.S. corporations that make relevant deductible payments to foreign affiliates. The excess of 10% of a corporation’s taxable income increased by those payments to foreign related parties over its regular tax liability, will be the base erosion tax due. BEAT provisions do not trigger adverse tax consequences for the U.S. subsidiaries of the Company considering the amount of payments made to foreign affiliates for management and support services;

Potential tax erosion in the U.S.: The Company does not expect to have material adverse tax consequences in the U.S. subsidiaries as a result of the measures previously described.

Note 19.- Third-party guarantees and commitments

Third-party guarantees

At the close of 2018 the overall sum of Bank Bond and Surety Insurance directly deposited by the subsidiaries of the Company as a guarantee to third parties (clients, financial entities and other third parties) amounted to $32,412 thousand attributed to operations of technical nature ($32,428 thousand as of December 31, 2017). In addition, the Company issued guarantees related to operations of technical nature amounting to $60 million as of December 31, 2018 ($112 million as of December 31, 2017).

Legal Proceedings

On October 17, 2016, ACT received a request for arbitration from the International Court of Arbitration of the International Chamber of Commerce presented by Pemex. Pemex was requesting compensation for damages caused by a fire that occurred in their facilities during the construction of the ACT cogeneration plant in December 2012, for a total amount of approximately $20 million. On July 5, 2017, Seguros Inbursa, the insurer of Pemex, joined as a second claimant in the process. In September 2018, ACT was notified that an agreement was reached between insurance companies according to which ACT would not have to pay any amount in relation to this arbitration. On December 19, 2018 the parties of the arbitration executed a settlement agreement to finalize the claim without any financial impact for ACT.

A number of Abengoa’s subcontractors and insurance companies that issued bonds covering Abengoa’s obligations under such contracts in the United States have included some of the non-recourse subsidiaries of the Company in the United States as co-defendants in claims against Abengoa. Generally, the subsidiaries of the Company have been dismissed as defendants at early stages of the processes but there remain pending cases including Arb Inc. with a potential total claim of approximately $33 million and a group of insurance companies that have addressed to a number of Abengoa’s subsidiaries and to Solana (Arizona Solar One) a potential claim for Abengoa related losses of approximately $20 million that could increase, according to the insurance companies, up to a maximum of up to approximately $200 million if all their exposure resulted in losses. The Company reached an agreement with Arb Inc. and all but one of the above-mentioned insurance companies, under which they agreed to dismiss their claims in exchange for payments of approximately $6.6 million, which have been made in 2018. The insurance company which did not join the agreement has temporarily stopped legal actions against the Company and the Company does not expect to have a material adverse effect.

In addition, an insurance company covering certain Abengoa’s obligations in Mexico has claimed certain amounts related to a potential loss. This claim is covered by existing indemnities from Abengoa. Nevertheless, the Company has reached an agreement under which Atlantica´s maximum theoretical exposure would in any case be limited to approximately $35 million, including $2.5 million to be held in an escrow account. On January 2019, the insurance company executed $2.5 million from the escrow account and Abengoa reimbursed such amount according to the existing indemnities in force between Atlantica and Abengoa. The payments by Atlantica would only happen if and when the actual loss has been confirmed, Abengoa has not fulfilled their obligations and after arbitration, if the Company initiates it.

Interests from other debts are primarily interests on the notes issued by ATS, ATN, ATN2, Atlantica Yield and Solaben Luxembourg and interests related to the investment from Liberty. Decrease in 2018 is primarily due to a lower increase of the amortized cost of the Liberty debt of $23 million compared to the year 2017 (see Note 16). Losses from interest rate derivatives designated as cash flow hedges correspond primarily to transfers from equity to financial expense when the hedged item is impacting the consolidated income statement.

According to an agreement reached with Abengoa in the third quarter of 2016, Abengoa acknowledged that Atlantica Yield is the legal owner of the dividends declared on February 24, 2017 and retained from Abengoa amounting to $10.4 million. As a result, the Company recorded $10.4 million as Other financial income on 2017 in accordance with the accounting treatment previously given to the ACBH dividend.

Other financial income in 2018 are primarily interests on deposits and on loan granted to third parties. In 2017, it included a $16.2 million income as a result of the termination of the currency swap agreement with Abengoa.

Other financial losses primarily include expenses for guarantees and letters of credit, wire transfers, other bank fees and other minor financial expenses.

Note 23.- Other information

23.1 Restricted Net assets

Certain of the consolidated entities are restricted from remitting certain funds to Atlantica Yield plc. as a result of a number of regulatory, contractual or statutory requirements. These restrictions are mainly related to standard requirements to maintain debt service coverage ratios. At December 31, 2018, the accumulated amount of the temporary restrictions for the entire restricted term of these affiliates was $625 million.

The Company performed a test on the restricted net assets of consolidated subsidiaries in accordance with Securities and Exchange Commission Regulation S-X Rule 12-04 and concluded the restricted net assets exceeded 25% of the consolidated net assets of the Company as of December 31, 2018. Therefore, the separate financial statements of Atlantica Yield, Plc. do have to be presented (see Appendix V (Schedule I) for details).

23.2 Subsequent events

On February 26, 2019, the Board of Directors of the Company approved a dividend of $0.37 per share, which is expected to be paid on or about March 22, 2019.

On January 29, 2019, PG&E Corporation and its regulated utility subsidiary, Pacific Gas and Electric Company (collectively “PG&E”), the off-taker for Atlantica Yield with respect to the Mojave plant, filed for reorganization under Chapter 11 of the Bankruptcy Code in the U.S. Bankruptcy Court for the Northern District of California (the “Bankruptcy Court”). As a consequence, PG&E has not paid the portion of the invoice corresponding to the electricity delivered for the period between January 1 and January 28, 2019, which was due on February 25, given that the services relate to the pre-petition period and any payment therefore would require approval by the Bankruptcy Court. However, PG&E has paid the portion of the invoice corresponding to the electricity delivered after January 28. A default of the PPA agreement with PG&E occurred with the PG&E bankruptcy filing and such default could trigger an event of default under our Mojave project finance agreement if certain other conditions were met, namely if (i) such default could reasonably be expected to result in a material adverse effect to Mojave or (ii) PG&E failed to assume the PPA within 60 days of its chapter 11 filing, extendable to 180 days provided that PG&E continues to perform under the PPA. As of December 31, 2018, Mojave had $739 million outstanding under its project financing agreement with the Federal Financing Bank, with a guarantee from the DOE. Additionally, Mojave represents approximately 13.5% of 2018 project level cash available for distribution. Chapter 11 bankruptcy is a complex process and the Company does not know at this time whether PG&E will seek to reject the PPA or not. However, PG&E has continued to be in compliance with the remaining terms and conditions of the PPA, including with all payment terms of the PPA up through the date hereof with the exception of services for prepetition services that became due and payable after the chapter 11 filing date. It remains possible that at any time during the chapter 11 proceeding, PG&E may decide to cease performing under the PPA and attempt to reject or renegotiate the terms of its contract with the Company. If PG&E rejected the contract and stopped making payments in accordance with the PPA, Mojave could fail in servicing its debt under its project finance agreement, which would also cause a default under the project finance agreement. If not cured or waived, an event of default in the project finance agreement could result in debt acceleration and, if such amounts were not timely paid, the DOE could decide to foreclose on the asset. The PG&E bankruptcy has heightened the risk that project level cash distributions could be restricted for an undetermined period of time, thereby impacting the corporate liquidity and corporate leverage of the Company. Mojave project cash distributions to the corporate level normally takes place at the end of the year, the last distribution received at the corporate level took place in December 2018. Unless the event or default is cured or waived, distributions may not be made during the pendency of the bankruptcy. Such events may have a material adverse effect on the business, financial condition, results of operations and cash flows of the Company.

On January 29, 2019, the Company entered into an agreement with Abengoa under the ROFO Agreement for the acquisition of Befesa Agua Tenés, S.L.U., a holding company which in turn owns a 51% stake of Tenes, a water desalination plant in Algeria, similar in several aspects to the Skikda and Honaine plants. Closing of the acquisition is subject to conditions precedent, including the approval by the Algerian administration. At this stage, the Company cannot guarantee it we will obtain this approval nor the expected timing of such approval. The price agreed for the equity value is $24.5 million, of which $19.9 million were paid in January 2019 as an advanced payment and the rest is expected to be paid once the conditions precedent are fulfilled. If all the conditions precedent were not fulfilled by September 30, 2019, the advanced payment shall be progressively reimbursed by Abengoa through a full cash-sweep of all the dividends to be received and in any case no later than September 30, 2031, together with an annual 12% interest.

F-63

Cadonal signed a PPA with UTE on December 28, 2012 for 100% of the electricity produced, approved by URSEA (Unidad Reguladora de Servicios de Energia y Agua). UTE pays a fixed tariff per MWh under the PPA, which is denominated in U.S. dollars and will be adjusted every January considering both U.S. and Uruguay´s inflation indexes and the exchange rate between Uruguayan pesos and U.S. dollars.

Solaben 2 & Solaben 3

The Solaben 2 and Solaben 3 are two 50 MW Concentrating Solar Power facilities and are part of Abengoa’s Extremadura Solar Complex. The Extremadura Solar Complex consists of four Concentrating Solar Power plants (Solaben 1, Solaben 2, Solaben 3 and Solaben 6), and is located in the municipality of Logrosan, Spain.

Solaben Electricidad Dos, S.A., or SE2, owns Solaben 2 and Solaben Electricidad Tres, S.A., or SE3, owns Solaben 3.

Renewable energy plants in Spain, like Solaben 2 and Solaben 3, are regulated by the Government through a series of laws and rulings which guarantee the owners of the plants a reasonable remuneration for their investments. Solaben 2 and Solaben 3 sell the power they produce into the wholesale electricity market, where offer and demand are matched and the pool price is determined, and also receive additional payments from the Comision Nacional de los Mercados y de la Competencia, or CNMC, the Spanish state-owned regulator.

Solacor 1 & Solacor 2

The Solacor 1 and Solacor 2 are two 50 MW Concentrating Solar Power facilities and are part of Abengoa’s El Carpio Solar Complex, located in the municipality of El Carpio, Spain.

ACT

The ACT plant is a gas-fired cogeneration facility with a rated capacity of approximately 300 MW and between 550 and 800 metric tons per hour of steam. The plant includes a substation and an approximately 52 mile and 115-kilowatt transmission line.

On September 18, 2009, ACT Energy México entered into the Pemex Conversion Services Agreement, or the Pemex CSA, with Petroleos Mexicanos, or Pemex. Pemex is a state-owned oil and gas company supervised by the Comision Reguladora de Energía (CRE), the Mexican state agency that regulates the energy industry. The Pemex CSA has a term of 20 years from the in-service date and will expire on March 31, 2033.

According to the Pemex CSA, ACT must provide, in exchange for a fixed price with escalation adjustments, services including the supply and transformation of natural gas and water into thermal energy and electricity. Part of the electricity is to be supplied directly to a Pemex facility nearby, allowing the Comision Federal de Electricidad (CFE) to supply less electricity to that facility. Approximately 90% of the electricity must be injected into the Mexican electricity network to be used by retail and industrial end customers of CFE in the region. Pemex is then entitled to receive an equivalent amount of energy in more than 1,000 of their facilities in other parts of the country from CFE, following an adjustment mechanism under the supervision of CFE.

The Pemex CSA is denominated in U.S. dollars.
