1.2        Forward-looking Statements

 

This annual report on Form 20-F contains forward-looking statements within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. These statements are not based on historical facts and reflect our expectations for future events and results. Most facts are uncertain because of their nature. Words such as “anticipate”, “believe”, “could”, “estimate”, “expect”, “should”, “plan”, “potential”, “predicts”, “prognosticate”, “project”, “target”, “achieve” and “intend”, among other similar expressions, are understood as forward-looking statements.

· dates by which certain areas will be developed or will come on-stream.

 

Our forward-looking statements are not guarantees of future performance and are subject to assumptions that may prove incorrect and to risks and uncertainties that are difficult to predict. Actual results could differ materially from those expressed or forecasted in any forward-looking statements as a result of a variety of factors. These factors may include, but are not limited to, the following:

 

· general economic and business conditions, including crude oil and other commodity prices, refining margins and prevailing exchange rates;

 

· competition;

 

· our ability to obtain financing;

 

  1

Our consolidated financial statements for the years ended December 31, 2014, 2015, 2016 and 2017 were prepared in accordance with IFRS as issued by IASB. References in this annual report to IFRS mean IFRS as issued by the IASB. Our date of transition to IFRS was January 1, 2014. Our consolidated financial statements for the year ended December 31, 2015 were our first set of consolidated financial statements prepared in accordance with IFRS.

 

IFRS differs in certain significant aspects from the current reporting standards as in effect in Colombia (“Colombian IFRS”), which is the accounting standard we use for local reporting purposes. As a result, our financial information presented under IFRS is not directly comparable to our financial information presented under Colombian IFRS. For a description of the differences between Colombian IFRS and IFRS see section Financial Review Summary of Differences between Internal Reporting Policies and IFRS .

 

Our consolidated financial statements were consolidated line by line and all transactions and balances between subsidiaries have been eliminated. These financial statements include the financial results of all subsidiary companies controlled, directly or indirectly, by Ecopetrol S.A. See Exhibit 1 – Consolidated companies, associates and joint ventures, to our consolidated financial statements included in this annual report.

 

As indicated in paragraphs 9 and 18 of the International Accounting Standard 27 “Consolidated and Separated Financial Statements” we must present our financial information on a consolidated basis as if we were a single entity, combining the financial statements of Ecopetrol S.A. and its subsidiaries line by line, adding assets, liabilities, shareholder’s equity, revenues and expenses of similar nature, removing the reciprocal items among members of the Ecopetrol Group and recognizing non-controlling interest. We present our operating information on a consolidated basis.

 

The regulations of the SEC do not require foreign private issuers that prepare their financial statements on the basis of IFRS to reconcile such financial statements to U.S. GAAP. Accordingly, while we have in the past reconciled our consolidated financial statements prepared in accordance with Colombian Government Entity GAAP to U.S. GAAP, those reconciliations are no longer presented in our filings before the SEC. We do continue to provide the disclosure required under the U.S. Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 932 “Extractive Activities—Oil and Gas” (which we refer to as ASC Topic 932), as this is required regardless of the basis of accounting on which we prepare our financial statements.

In this annual report, references to “US$” or “U.S. dollars” are to United States dollars and references to “COP$” “Colombian Peso” or “Colombian Pesos” are to Colombian Pesos, the Ecopetrol Group’s functional and presentation currency under which we prepare our consolidated financial statements. This annual report translates certain Colombian Peso amounts into U.S. dollars at specified rates solely for the convenience of the reader. Unless otherwise indicated, such Colombian Peso amounts have been translated at the rate of COP$2,951.15 per US$1.00, which corresponds to the Tasa Representativa Promedio del Mercado (TRM), or Average Representative Market Exchange Rate, for 2017. Such conversion should not be construed as a representation that the Colombian Peso amounts correspond to, or have been or could be converted into, U.S. dollars at that rate or any other rate. On April 16, 2018, the Representative Market Exchange Rate was COP$2,705.34 per US$1.00.

 

Certain figures shown in this annual report have been subject to rounding adjustments and, accordingly, certain totals may therefore not precisely equal the sum of the numbers presented. In this annual report a billion is equal to one with nine zeros.

 

2. Strategy and Market Overview

 

After experiencing the lowest price level in recent years in 2016, the ICE Brent price underwent a gradual recovery during the second half of 2017. The agreement to cut production between OPEC and some Non-OPEC producers in 2017 was the key factor that boosted the crude market towards a path of rebalancing. In addition, price levels were also supported by lower supply in the Middle East and North Africa as a result of unrest and political tensions. On the other hand, the demand for crude oil was favored by improved economic performance in emerging countries, growing import requirements from independent refiners in China and the building of petroleum reserves in Asian countries.

 

According to estimates of the Energy Information Administration (“EIA”), in 2017 global oil demand grew 0.89 mboepd in excess of total supply. Non-OPEC supply climbed 0.7 mboepd, primarily due to higher US production. On the other hand, OPEC, in compliance with the cut agreement, reduced its crude flow ex NGLs by 0.24 mboepd, mainly in Saudi Arabia (-0.33 mboepd) and Venezuela (-0.26 mboepd). Global demand surprised the market by increasing 1.63 mboepd, mainly due to greater demand in Non-OECD countries.

Although international oil prices and global demand and supply dynamics are significant factors affecting our business and financial condition, Colombia’s local economic factors have also influenced and could continue to influence our performance given that we conduct most of our business in Colombia.

 

The performance of Colombia’s gross domestic product (GDP) is one of the main drivers of fuel consumption in Colombia. According to the National Administrative Department of Statistics (DANE for its acronym in Spanish), during 2017 Colombia’s GDP grew 1.8% in real terms, as compared to 2016. The industries with the best performance were financial institutions, insurance, real estate and business services, and agriculture. On the other hand, mining, construction and transportation had the worst performance. Local sales of liquid fuels increased by 3%, boosted by higher sales of gasoline and diesel.

 

Natural gas demand in Colombia fell 7% in 2017 due to lower natural gas demand from power plants compared to 2016 when the “El Niño phenomenon” occurred. Although sales were affected by this factor, Ecopetrol’s short term strategy was focused on promoting demand to mitigate the impact on sales. According to the Energy and Mines Planning Unit (UPME for its acronym in Spanish), under the medium scenario of supply and demand for October 2017, the Colombian natural gas market might experience a deficit after 2024.

 

2.1        Our Corporate Strategy

 

The 2017-2020 business plan is focused on value generation, profitability and financial sustainability and allows for upsides in case of potential price increases. The plan, released in the third quarter of 2016, has been adjusted to a lower price environment of US$50 per barrel on average.

 

The three pillars of the plan are: (i) cash flow focus and cost efficiency, (ii) strict capital discipline and (iii) profitable reserves and production growth.

 

Cash flow focus and cost efficiency : In 2015, we launched the 2015-2020 Transformation Program (the “Transformation Program”) with a goal of increasing our efficiency and decreasing costs. The Transformation Program has allowed us to decrease structural costs by US$2.4 billion compared to 2014. Such reduction has been accomplished due to the implementation of initiatives through our different business segments and corporate areas.

 

The business plan entails a second phase of the Transformation Program, with activities aimed to achieve excellence in project planning and execution as well as in our production, transportation, refining and marketing operations.

 

Capital discipline : We have preserved a rigorous level of capital discipline through the adjustment of project planning processes and the adoption of controls to ensure that projects are delivered efficiently, within the expected time frame and budget, and generate adequate return on investments. For this purpose, Ecopetrol S.A. created the Vicepresidency of Projects and Engineering to provide best-in-class project delivery, through “Ecopetrol Project Development” (“EDP”). EDP is the framework for maturing opportunities and employs best practice guidelines for projects. It is consistently applied with maximum synergy and standardization between Upstream, Midstream and Downstream projects.

 

The plan calls for investments of approximately US$13 billion between 2017 and 2020. By 2020, approximately 80-90% of this investment will be allocated to the development of upstream projects, while investments in transportation and refining will seek to improve operational integrity and reliability.

 

Profitable growth in production and exploration : One of the pillars of the revised business plan is the view that a strong production portfolio and a greater exploratory success will bring about profitable growth. Under a price scenario of US$50 per barrel, production should average 740-760 thousand barrels of oil equivalent per day by 2020, approximately 6% growth from 2017. Approximately 98% of this production will come from the current producing assets.

 

In exploration, the plan estimates the incorporation of approximately 1,000 million barrels of contingent resources. In respect of adding reserves, we highlight the results of the exploratory campaigns in the Colombian Caribbean offshore and the U.S. Gulf of Mexico.

 

  5  

 

 

During the period 2016 – 2020, Ecopetrol expects to add 600 million barrels of proven reserves from current fields and exploration. Further, the business plan’s financial flexibility will allow Ecopetrol to evaluate inorganic growth opportunities to accelerate reserves addition.

 

As part of our long-term strategic planning process, we are in the process of developing strategic guidelines for the following years (“Strategy 2020+”). This analysis takes into account financial and sustainability parameters, operational excellence, portfolio diversification and synergies through the entire value chain. Strategy 2020+ will harmonize the requirements of the Upstream, Downstream and Midstream businesses, plus corporate areas, thus consolidating the long-term strategy of Ecopetrol.

 

In line with the business plan, in November 2017, the Board of Directors approved a US$3.5-$4.0 billion investment plan for 2018. The Ecopetrol Group plans to produce 715-725 thousand barrels of oil equivalent per day during 2018. The table below sets forth the details of the investment plan per business segment.

Exploration

 

In the exploration segment, US$400-US$450 million will be allocated mainly to the evaluation and appraisal of discoveries and ongoing exploration efforts of Ecopetrol S.A. (approximately 49%), Hocol S.A. (“Hocol”) (approximately 17%), Ecopetrol America Inc. (approximately 9%), ECP Hidrocarburos Mexico (approximately 4%), Ecopetrol Costa Afuera (approximately 17%) and Ecopetrol Brazil (approximately 4%).

 

Production

 

In the production segment, US$2,580-US$2,950 million will be allocated mainly to the execution of development and incremental production projects of Ecopetrol S.A. (approximately 94%) primarily at Akacias-CPO09, Castilla, Cupiagua-Cusiana, La Cira-Infantas, Piedemonte, Rubiales, Yarigui-Cantagallo, Provincia and Llanito-Lisama fields. We have also allocated funds for our affiliates and subsidiaries as follows: approximately 2% for the operation and maintenance of fields of Ecopetrol America Inc. in the U.S. Gulf of Mexico, approximately 3% to Hocol, approximately 1% to Equion and Savia.

 

Transportation and logistics

 

In the transportation and logistics segment, US$270-US$300 million will be allocated to investments focused on risk mitigation and maintenance. The segment is seeking a higher efficiency in operations and maintenance practices.

 

Refining, petrochemicals and biofuels

 

In the refining, petrochemicals and biofuels segment, US$220-US$250 million will be allocated to programs to improve operations at Reficar and the Barrancabermeja refinery through initiatives aimed to increase revenues, enhancing integrity management, improve efficiency and reduce operational costs. The segment is seeking a higher efficiency in operations and maintenance practices. In accordance with the capital discipline criteria we established to ensure growth and financial sustainability, the Barrancabermeja refinery modernization plan will continue to be suspended. Meanwhile, Ecopetrol continues to analyze and implement alternatives for improving the competitiveness of this refinery including, among others, the use of other sources of crude oil as well as removing operational and logistical restrictions.

3. Business Overview

 

3.1        Our History

 

We were formed in 1951 by the Colombian government as Empresa Colombiana de Petróleos and began operating the crude oil fields at La Cira-Infantas, the oldest Colombian oil field whose production started in 1918, and the pipeline that connected that field with the Barrancabermeja Refinery and the port of Cartagena. In 1961, we assumed the direct operation of the Barrancabermeja Refinery and continued its transformation into an industrial complex. In 1974, we acquired the Cartagena Refinery, which had been in operation since 1957. Pursuant to Decree 0062 of 1970, we were transformed into a governmental industrial and commercial company.

 

In 2003 pursuant to Decree Law 1760, the Agencia Nacional de Hidrocarburos - National Hydrocarbons Agency (the “ANH”) was created and Ecopetrol’s public role as administrator and regulator of the national hydrocarbons resources was transferred to the ANH. Ecopetrol modified its organic structure and became Ecopetrol S.A., a public stock-holding corporation, one hundred percent state-owned, and continued the development of exploration and production activities in a competitive basis with autonomy over our business decisions. Since 2006, according to Law 1118, we have been evolving from a wholly state-owned entity to a mixed-economy company with private capital. This process has resulted in a substantial change in the legal framework to which we are subject and in the nature of our relationship with the Nation, as our controlling shareholder. As of March 23, 2018, pursuant to our amended bylaws, the duration of the Company is 100 years.

 

We carried out our initial public offering in November 2007 when our common shares became listed on the Colombian Stock Exchange. Our American Depository Shares (“ADSs”) were listed on the New York Stock Exchange in 2008. Starting in August 2010, our ADSs began trading on the Toronto Stock Exchange (“TSX”) under the symbol “ECP.” On February 17, 2016, we announced our application for voluntary delisting from the TSX. On March 2, 2016, our ADR’s were officially delisted from the TSX. On December 7, 2017, we applied to the Alberta Securities Commission and the Ontario Securities Commission to cease our reporting requirements due to our delisting process and are currently awaiting responses from both. In the meantime, we continue to be subject of the reporting requirements of such Commissions.

 

3.2        Our Corporate Structure

 

We operate in the following business segments: i) Exploration and Production; ii) Transportation and Logistics; iii) Refining, Petrochemicals, and Biofuels.

 

Our subsidiaries Refinería de Cartagena (Reficar), Cenit and Ocensa are significant subsidiaries as such term is defined under SEC Regulation S-X.

 

We have a number of directly and indirectly held subsidiaries both in Colombia and abroad. Our subsidiaries are either directly owned by us or indirectly owned by us through one or more of our other subsidiaries. As of March 31, 2018, we have 9 directly owned and 29 indirectly owned subsidiaries.

 

During 2017, the following changes were made to the Ecopetrol Group’s structure:

 

(i) In January 2017, the merger by absorption between Sento and Cenit was completed, with the latter being the absorbing company as of January 6, 2017. As a result, Cenit is now the direct holder of a 51.28% equity interest in the outstanding capital stock of ODC. However, this restructuring had no impact on our consolidated financial statements.

 

(ii) In August 2017, Ecopetrol S.A. incorporated a subsidiary ECP Hidrocarburos Mexico S.A.de C.V., which will be responsible for exploration and production activities in Mexico.

 

  7  

 

 

(iii) In August 2017, Ecopetrol S.A. wound up certain foreign subsidiaries, namely Ecopetrol Global Capital S.L.U. and ECP Oil and Gas Germany GmbH. Ecopetrol Global Capital S.L.U. was liquidated in April 4, 2018.

 

(iv) In March 2018, Ecopetrol S.A. incorporated a new subsidiary, Ecopetrol Energía SAS E.S.P., domiciled in Colombia, which will be responsible for commercialization of electric power for the Business Group.

 

Exhibit 8.1 to this annual report identifies our principal operating subsidiaries, their respective countries of incorporation, and our percentage ownership in each (both directly and indirectly through other subsidiaries), in each case as of March 31, 2018.

 

Graph 2 – Ecopetrol Corporate Structure

 

 

 

The stock ownership percentage listed refers to Ecopetrol S.A.’s direct and indirect participation. The data in this structure shows neither the whole ownership nor its decimal figures, so they will be used only for information purposes.

 

The so-called shareholding (Ecopetrol S.A.’s direct participation), affiliated, subsidiary companies are listed, as well as the stock interest of Ecopetrol S.A.’s subordinate companies.

 

In 2017, Ecopetrol completed the divestment of its stake in Empresa de Energía de Bogotá S.A. E.S.P. EEB for a total of COP$1,124 billion. The operation was carried out in accordance with the procedures defined by the Law 226 of 1995, the Decree 2305 of November 13, 2014, and the Decree 2110 of December 22 of 2016.

 

We currently own 100% of the total outstanding shares of Propilco. In connection with the review of its long-term strategy, the Board of Directors decided to suspend the 2016 plan to sell Ecopetrol’s shares in Propilco.

 

3.3        Our Business

 

We are a vertically integrated oil company with a presence primarily in Colombia and with activities in Peru, Brazil, Mexico and the U.S. Gulf Coast. The Nation currently controls 88.49% of our voting capital stock. We are among the world’s biggest state-owned companies, ranking 559 based on Forbes Global 2000 Ranking - 2017. We play a key role in the local Colombian hydrocarbon market.

3.4        Exploration and Production

 

Our exploration and production business segment includes exploration, development and production activities in Colombia and abroad. We began local exploration in 1955 and international exploration in 2006. We conduct exploration and production activities directly in Ecopetrol S.A., through some of our subsidiaries, and through joint ventures with third parties. As of December 31, 2017, we were the largest operator and the largest producer of crude oil and natural gas in Colombia, maintaining the largest acreage exploration position in Colombia.

 

For purposes of this exploration section, “we” refers to Ecopetrol S.A., its subsidiaries and partnerships in which Ecopetrol has an interest. Unless otherwise stated, all figures are given before deducting royalties.

 

3.4.1        Exploration Activities

 

Under the framework of the Exploration Strategy 2017-2020, Ecopetrol is aiming to incorporate at least 1 billion barrels of contingent resources in high reward projects, concentrated in (i) Offshore Colombia, (ii) re-evaluating opportunities onshore Colombia, and (iii) international areas such as the Gulf of Mexico, Brazil and other areas within the Americas.

 

Graph 3- Sedimentary Basins where Ecopetrol executes exploration activities

 

 

 

During 2017, the exploration strategy was directed at leveraging our goal on three working fronts: onshore Colombia, offshore Caribbean, and strengthening and diversifying our exploration overseas.

 

3.4.1.1        Exploration Activities in Colombia

 

During 2017, Ecopetrol and its subsidiaries conducted drilling operations in 16 exploration wells (A3/A2) and in 2 appraisal wells (A1) in Colombia. Of these 16 wells, 3 were successful, 6 were plugged and abandoned, and 7 were under evaluation as of December 31, 2017. This activity was concentrated mainly in the following basins: onshore Sinu, Upper Magdalena Valley, Middle Magdalena Valley, Guajira and offshore Sinu.

 

  9  

 

 

In terms of onshore Colombia, we focused our exploration efforts in searching for hydrocarbons in mature basins, near field exploration and close to existing production infrastructure. Additionally, we succeeded in increasing our participation in blocks Fuerte Sur (Sinu offshore basin) and CPO-17 (Llanos basin), from 50% to 100% in both cases.

 

The following table sets forth for the periods indicated; the number of gross and net productive and dry exploratory wells drilled by us and our joint venture partners and the exploratory wells drilled by third parties pursuant to sole risk contracts with us.

Ecopetrol drilled three successful wells in Colombia in 2017: (i) Purple Angel-1 well, where Ecopetrol holds a 50% working interest and Anadarko the remaining 50% at Purple Angel block, (ii) Gorgon-1 well, where Ecopetrol holds a 50% working interest and Anadarko the remaining 50% at Purple Angel block, and (iii) Coyote-1, where Ecopetrol holds a 50% working interest, and Parex Resources Inc. as operator the remaining 50% at Playon block.

 

Six wells were plugged and abandoned. Three of the wells were located in the Colombian Caribbean: (i) Molusco-1 well, where Ecopetrol holds a 50% working interest through its affiliate Ecopetrol Costa Afuera S.A.S (“ECAS”) and ONGC with the remaining 50% at RC-9 block, which was a dry well, (ii) Siluro-1B well, operated by Repsol at RC-11 block, which was a dry well and (iii) Brama-1 well, operated by Petrobras at Tayrona block, which was a dry well. The other three wells were located onshore in Colombia and were determined to be dry: (i) Trogon-1 well, where Ecopetrol holds a 55% working interest as operator and Repsol the remaining 45% at CPO-9 block, (ii) Landero-1 well, where Ecopetrol holds an 100% working interest at Middle Magdalena Valley and (iii) Lunera-1 well, where Hocol holds an 100% working interest as operator at VSM-9 block.

 

In addition, two appraisal wells were drilled. The first, Capachos 2 ST located at Capachos block operated by Parex Resources Inc., which holds a 50% working interest in partnership with Ecopetrol holding the remaining 50%. This well was under evaluation as of December 31, 2017, but has been declared successful since. The appraisal well Bullerengue Sur-3 located at SSJN1 Block operated by Lewis Energy, which holds a 50% working interest in partnership, with Ecopetrol holding the remaining 50% was plugged and abandoned.

 

Seismic

 

In Colombia our subsidiary Hocol S.A. acquired a total of 518 km of 2D in blocks SN 8 and SN 18.

 

3.4.1.2        Exploration Activities Outside of Colombia

 

Our international exploration strategy is focused on participating in bidding rounds to secure blocks available for exploration and entering into joint ventures with international and regional oil companies. We believe exploring outside Colombia allows us to diversify our risks and improve the possibilities of increasing our crude oil and natural gas reserves.

 

In partnership with Petronas and Pemex, respectively, we were awarded block 6 and 8 in Mexico during the bidding round 2.1 and our Mexican subsidiary, ECP Hidrocarburos Mexico S.A. de C.V., has entered into petroleum contracts in connection therewith. Additionally, in a 50% partnership with Repsol E&P USA Inc., as operator, we were awarded blocks Garden Banks 77, 78, 121 and 122 in the Gulf of Mexico (US) through our American subsidiary, Ecopetrol America Inc.

 

  11  

 

 

With respect to our exploratory drilling outside of Colombia, as set forth in the table below, in 2017 our subsidiary Ecopetrol America Inc. drilled two wells: (i) Warrior-2 and (ii) Warrior-2 ST-1, both located in the Green Canyon area in the Gulf of Mexico (US). These wells contained hydrocarbons, both wells were deemed non-commercial due to thin compartmentalized reservoirs, and were plugged and abandoned. The associated contingent resources of this discovery are currently under evaluation. Ecopetrol America Inc. has a 30% interest in this area, with our partner Anadarko holding the remaining 70% interest and acting as operator.

 

The following table sets forth information on our exploratory drilling for the periods indicated.

Seismic

 

Our subsidiary, Ecopetrol Brazil, completed the acquisition of a marine 3D seismic program of 446 km2 in block FZA-M-330, in the Foz de Amazonas basin (Brazil). Ecopetrol Brazil holds a 70% equity interest in this block with JX Nippon holding the remaining 30% interest.

 

Ecopetrol America Inc purchased the 3D seismic program EDGE of 28.000 km2 in Green Canyon. The seimic program contributed, to mitigate subsalt uncertainty and to mature leads for lease sales.

 

3.4.2        Production Activities

 

Our consolidated average production was 715.1 thousand boepd in 2017, a decrease of approximately 3 thousand boepd as compared to 2016. This decrease is mainly the result of the natural production decline of our fields, partially offset by an increase in upstream investments during 2017.

 

The following table summarizes the results of our oil and gas production activities for the periods indicated:

3.4.2.1        Production Activities in Colombia

 

3.4.2.1.1 Ecopetrol S.A.’s Production Activities in Colombia

 

For the year ended December 31, 2017, Ecopetrol S.A. was the largest participant in the Colombian hydrocarbons industry, accounting for approximately 64% of crude oil production (according to calculations made by Ecopetrol based on information from the Ministry of Mines and Energy) and approximately 68% of natural gas production (according to calculations made by Ecopetrol based on information from the Ministry of Mines and Energy). Also during 2017, Ecopetrol S.A. carried out development drilling mainly in the Orinoquia and Middle Magdalena regions, drilling 475 development wells; 199 of those through direct operations and 276 through joint ventures.

 

In terms of operational structure, Ecopetrol S.A. manages its production operations through a regional organization. Since July 1, 2014, three regional Vice-Presidencies were created: Central, Orinoquia and Southern. After the company took over the operations of the Rubiales field in July of 2016, a new Vice-Presidency, the Eastern Region, was incorporated to this scheme. Our operating assets are distributed in the following regions:

 

· Central Region: comprising 30 fields with active production in 2017.

 

· Orinoquía Region: comprising 23 fields with active production in 2017.

 

· Southern Region: comprising 36 fields with active production in 2017.

  

· Eastern Region: comprising 2 fields with active production in 2017.

 

  13  

 

 

A fifth Vice-Presidency, the Vice-Presidency of Associated Operations, is responsible for all of the production activities in which a partner is involved, regardless of the location of such activities in Colombia. This Vice- Presidency is comprised of 121 fields with active production in 2017.

 

The map below indicates the locations of Ecopetrol S.A’s operations with production information for each of our administrative regions following in the subsequent paragraphs.

 

Graph 4 – Ecopetrol S.A. Operations in Colombia

 

 

 

Note: VAS is the countrywide Vice-presidency.

 

Crude Oil Production

 

The average daily production of crude oil in Colombia by Ecopetrol S.A. (excluding its subsidiaries), was 545 mbod in 2017, 7.1 mbod lower than in 2016, which represents a year-to-year decrease of 1.3%.

 

However, it is important to highlight that since July of 2016 we took over the operations of the Rubiales and Cusiana fields. A plan was set up more than two years in advance, which allowed us to successfully transition between operators, without any technical, operational or communities’ issues in any of the two fields. In July 2017, Ecopetrol completed the first year of operating in the Rubiales field. During 2017, we invested in the asset with the drilling of 127 wells and the implementation of efficiency measures, thereby continuing to mitigate historical production declines.

 

The following chart summarizes Ecopetrol S.A.’s average daily crude oil production in Colombia by Region, prior to deducting royalties, for the periods indicated.

Ecopetrol S.A.’s crude oil production during 2017 consisted of approximately 36% light and medium crudes and 64% heavy crudes. In 2016, approximately 37% of the crude oil production corresponded to light and medium crudes and 63% to heavy crudes. In 2015, approximately 40% of the crude oil production corresponded to light and medium crudes and 60% to heavy crudes.

 

Natural Gas Production

 

In 2017, the average daily production of natural gas by Ecopetrol S.A. reached 111 mboed, including natural gas liquids (“NGLs”), corresponding to a 4.3% decrease in comparison to 2016 production.

 

We have three main natural gas production fields, Guajira, Cusiana and Cupiagua. In the Guajira field, we have partnered with Chevron who operates the field. The development of Cusiana field had a change in participation, because Tauramena joint venture expired on July 3, 2016. The Tauramena block is part of the Cusiana unified exploitation plan. As a consequence of the termination of the Tauramena joint venture, Ecopetrol’s participation increased from 63.4% to 97.8%, and Ecopetrol assumed the operation of the Cusiana unified exploitation plan. Ecopetrol S.A. is the operator of the Cupiagua field and other wells previously under the Recetor contract that were transferred from Equion to Ecopetrol as a result of the full return of the Recetor Field to Ecopetrol on May 30, 2017.

 

Of our total natural gas production during the year ended December 31, 2017, approximately 24% was supplied from the Guajira field, 29% from the Cusiana field, 23% from the Cupiagua field and the remaining 24% from other fields.

 

The following table sets forth Ecopetrol S.A.’s average daily natural gas production in Colombia, including NGLs, prior to deducting royalties, for the years ended on December 31, 2017, 2016, and 2015.

Projects to Increase Recovery Factor:

 

During 2017 Ecopetrol prioritized opportunities within its recovery factor increase program, keeping the following active pilots in operation: waterflooding (WF) in Chichimene, Castilla, Apiay and Suria; Chemical Enhanced Oil Recovery (CEOR) in Chichimene, Yarigui and Casabe and Vapor Injection Continue (ICV) in Teca; and developing additional ones: WF in Nutria and Tisquirama and CEOR in Cira and Geles.

 

The Chichimene and Castilla fields have continued reporting increases in their recovery factors between 8% and 12% in their pilot areas. Additionally, in 2017, we evaluated the steam injection pilots in the Teca project, located in the Middle Magdalena Valley, where we also obtained positive production responses.

 

At the Chichimene field, nitrogen injection pilots were successfully completed. We are currently analyzing the production curve, and air injection is expected to begin in the second half of 2018.

 

Among the main results of the pilots in 2017, it is important to highlight that 73 mmboe of proven reserves and 174 mmboe of contingent resources were incorporated. In addition, four new recovery projects were conceptualized (WF in Chichimene, Castilla and Llanito-Gala-Galan, being among the most important ones).

 

35 recovery pilots have started since the beginning of the recovery factor increase program in 2008. Out of these pilots, 28 have shown positive results, of which 11 are now in expansion stage, 11 are operating and six were closed.

Crude oil export sales in 2017 decreased by 19 mbopd as compared to 2016 mainly due to higher consumption of the local refineries. Ecopetrol’s crude oil export sales are traded both in the spot and contract markets, primarily to refiners in the United States, Asia and Europe.

 

The Castilla blend is the main type of crude oil for export sales, with 315.1 mbopd sold during 2017 (a 76% share of our crude oil basket) followed by the Vasconia Norte with 29.1 mbopd (a 7% share in our crude oil basket), Vasconia with 15.2 mbopd (a 4% share of our crude oil basket), and the South blend with 13.0 mbopd (a 3% share of our crude oil basket).

 

  22  

 

 

Ecopetrol placed its exports in markets that represent the best value for its crudes. The United States remained the main destination representing almost a half of our crude exports. In particular, lower supply of other heavy and intermediate grades generated new opportunities for Colombian crudes in the US. In addition, the percentage of exports to Asia increased from 15% in 2016 to 25% in 2017 due to the expansion of refining capacity and higher imports in that market. Ecopetrol’s crude basket reached a nine year high, discounted only by US$ 6.9/bl below the ICE Brent price.

 

Crude Oil Purchase Contracts

 

Ecopetrol has signed several crude oil purchase contracts with third parties and business partners. Ecopetrol also purchases crude oil from the ANH as royalties. This oil is processed in Ecopetrol’s refineries or exported. The purchase price is referenced to export parity based on international market prices plus a commercial fee.

 

The contract terms are typically linked to the term of the exploration and production contracts signed with our partners. Other contract clauses such as price and point of delivery vary and may be subject to renegotiation during the term of the contract. Certain purchase contracts are not linked to joint venture agreements and may be extended and renegotiated by the parties.

 

The table below sets forth the volumes of crude oil purchased from our business partners and third parties and volumes of crude oil purchased from the ANH from royalties for the years ended on December 31, 2017, 2016 and 2015.

Crude oil purchased from third parties     16.7       15.5       15.6  
Crude oil imported from third parties     24.8       22.0       1.8  

 

Import of Diluents

 

In 2017, Ecopetrol decreased the imports of diluent by 8% (5 mbpd) compared to 2016. Diluent is used to transport our heavy crudes through the pipeline system and the reduction is due to optimizations in dilution processes within the transformation plan last year.

 

Natural Gas Sales

 

Ecopetrol sells natural gas to distribution companies through firm, interruptible and conditional contracts. These distributors supply natural gas to the residential market, as compressed natural gas for vehicles market and to large industrials in Colombia. We also market and sell natural gas directly to the industrial sector and to gas-fired power plants.

 

Ecopetrol’s natural gas sales and self-consumption decreased by 2.8% (2.2 mboepd) compared to 2016 due to lower demand from natural gas fired power plants.

Natural Gas Delivery Commitments

 

The table below sets forth the commitments we have in Colombia under firm contracts with local natural gas distribution companies, local industries, gas fired power generators, and internal agreements with our refineries and fields.

Neither Equion nor Savia Peru are included in the table above since they do not consolidate within Ecopetrol Group. Data was updated based on current contracts and the official report made to the Ministry of Mines and Energy in 2017.During 2017 the Energy and Gas Regulatory Commission published a new resolution modifying the existing trading rules in the Colombian natural gas market. One of the major changes provided Ecopetrol the opportunity to negotiate and subscribe one-year term agreements starting on December 2018. See the section Business Overview—Applicable Laws and Regulations—Regulation of the Natural Gas Market .

 

Refined Products

 

Domestic sales of refined products increased by 8.6 mboepd, an increase of 2.9% compared to 2016. This increase is primarily the result of: (i) a 2.7%, or 3.8 mboepd, increase in middle distillates sales mainly due to the reactivation of oil service and the mining sector, (ii) a 2.2%, or 2.4 mboepd, increase in gasoline as a result of a decrease in the production of ethanol for gasoline blending, (iii) a 32.8%, or 2.1 mboepd, increase in fuel oil sales mainly as a result of new contracts, (iv) a 3.1%, or 0.5 mboepd, increase in LPG sales primarily as a result of the stabilization of production at Reficar and imports of LPG carried out by Ecopetrol to meet the national demand deficit, and (v) a 1.6%, or a 0.3 mboepd, decrease in petrochemicals sales, due to a decrease in asphalt and aromatic solvents sales by Ecopetrol S.A, as a consequence of non-execution of 4G road construction projects and contraction of the domestic demand and availability problems for aliphatic solvent.

 

Exports of products decreased by 25.7% compared to 2016 (18.7 mbd from Reficar and 17.7 mbd from Ecopetrol) primarily due to a decrease in our exports of fuel oil and high sulfur diesel. The 40% or 27 mbd, decrease in our fuel oil exports was primarily due to start up activities at our Coker Unit. The 39% or 11 mbd, decrease in our diesel exports was primarily due to our production of ultralow sulfur diesel for our local market.

 

3.4.3        Reserves

 

The reserves audit process was conducted in accordance with SEC definitions and rules set forth in Rule 4-10(a) of Regulation S-X and the disclosure guidelines contained in the SEC’s Modernization of Oil and Gas Reporting final rule dated December 31, 2008 and effective as of January 1, 2010.

 

The estimated reserve amounts presented in this report, as of December 31, 2017, are based on the average prices during the 12-month period prior to the ending date of the period covered in this report, determined as the unweighted arithmetic averages of the prices in effect on the first day of the month for each month within such period, unless prices were defined by contractual arrangements, as required by the SEC regulations.

 

Our crude oil and natural gas net proved reserves include reserves from our subsidiaries located in the United States (Gulf of Mexico) and Peru, and Equion and Hocol’s assets in Colombia.

The conversion rate used is 5,700 standard cubic feet = 1 barrel of oil equivalent.

 

We are required, as are all oil companies undertaking exploratory and production activities in Colombia, to pay a percentage of our production to the Government as royalties. However, the ANH’s Resolution 877 of 2013, Resolution 351 of 2014 and Resolution 640 of 2014 require natural gas royalties to be paid in cash, which means that the determination of the property rights to the quantities of natural gas we produce is based on the total volume produced without deductions on account of royalties. The main producing gas fields are Cusiana, Cupiagua, Pauto, Chuchupa, Gibraltar, Ballena and Mamey.

 

Ecopetrol S.A. owns 100% of Cenit, a subsidiary that operates in Colombia and is dedicated to the storage and transportation of hydrocarbons through pipelines. Cenit provides transportation services for the entire Ecopetrol Group and we fully consolidate Cenit into our consolidated results of operations. Therefore, the difference between the tariffs set by the Ministry of Mines and Energy and the real transportation costs (fixed and variable operating expenses) does not affect our consolidated income statement. Thus, in presenting our reserves information in 2016 and 2017 annual report, we have used our real transportation costs, rather than the regular tariffs set by the Ministry of Mines and Energy.

 

The following table summarizes our proved oil, NGL and natural gas reserves, which includes 304 billion standard cubic feet of fuel gas within our natural gas results and 562 billion cubic feet of royalties, as of December 31, 2017.

Revisions of Previous Estimates

 

In 2017, revisions increased reserves by 174 million boe, mainly as a result of:

 

(i) An increase of 49 million boe due to the continuous development of the Castilla, Chichimene, Rubiales, Caño Sur and Akacias fields of which a 32 million boe increase in reserves is due to the new development projects in the Caño Sur and Akacias fields, and a 17 million boe increase in reserves is due to development activities and improved reservoir performance in the Chichimene, Castilla and Rubiales fields.

 

(ii) An increase of 23 million boe due to improved natural gas sales in the Cupiagua and Pauto fields, which in turn was due to better performance and improved output of such fields. Additionally, new gas and NGL projects in the Cupiagua Sur field led to a 27 million boe increase in reserves. Revisions in the Nutria, Llanito, Tibu, Casabe and Cohembi fields as a result of drilling activities and better production performance accounted for a 23 million boe increase in reserves.

 

(iii) The remaining 30%, or 52 million boe, increase in reserves was due to varying increases and decreases from other fields.

 

Improved Recovery

 

In 2017, improved recovery increased reserves by 73 million boe. The additions were associated with new proved areas under waterflooding in the Chichimene and Castilla fields (47 million boe increase).

 

The continued development of waterflooding projects at existing wells in the Tibu, La Cira, Infantas, Casabe and Guando SW fields, accounting for a 24 million boe increase. The remaining 3%, or 2 million boe, increase was due primarily to water injection pilots in the Apiay and Palogrande fields.

 

Extensions and Discoveries

 

Extensions and discoveries during 2017 amounted to 44 million boe primarily due to extensions of proved acreage mainly from activities in new proved areas in the Rubiales, Castilla, Pauto, Cajua and Arrayan fields, which accounted for 39 million boe of the total of 44 million boe from extensions of proved acreage. The remaining 5 million boe corresponds to smaller changes in several other fields.

 

Purchases

 

Ecopetrol S.A.’s purchases of minerals in 2017 included the acquisition of an additional participation of 11.6% in the K2 Field by Ecopetrol America Inc which represented 4 million boe.

 

Development of reserves

 

As of December 31, 2017, our total proved undeveloped oil and gas reserves amounted to 287 million boe, 24% of which is related to the drilling activities in the Castilla field, 11% is related to gas sale projects in the Pauto and Cupiagua fields and 42% of which is related to the development activities in the Rubiales, Caño Sur, Chichimene, Yarigui, Tibu, Nutria, Palagua and Quifa fields. The Moriche, Ocelote, Akacias, Dina, Casabe, Llanito, La Cira and Cajua fields collectively accounted for 11% of total proved undeveloped oil and gas reserves with the remaining 12% from several other fields.

 

  27  

 

 

Our proved undeveloped reserves represent 17% of our total proved reserves.

 

The Ecopetrol’s year-end development plans are consistent with SEC guidelines for the development of proved undeveloped reserves within five years.

 

The following table reflects the developed and undeveloped proved reserves estimates through the past three fiscal years.

Of the total amount of proved undeveloped reserves that Ecopetrol had at the end of 2016 (269.3 million boe), we converted approximately 53 million boe, or 20%, to proven developed reserves during 2017 (286.6 million boe), primarily associated with the development of crude oil and gas projects in the Castilla, Rubiales, Pauto, Quifa, La Cira Infantas and K2 fields. These projects accounted for approximately 89% of the total conversion while the remaining 11% is associated with development execution in other fields such as the Chichimene and Ocelote fields, among others. The amount of investments made during 2017 to convert proved undeveloped reserves to proved developed reserves was US$494 million.

 

Changes in Undeveloped Proved Reserves

 

The following table reflects the main changes in undeveloped proved reserves during 2017.

Reserve Estimation Process

 

Ecopetrol’s reserves process is coordinated by the Corporate Reserves Manager, a highly experienced geologist and engineer, who reports to the Upstream Chief Financial Officer. The reserves audit group is comprised of reserves coordinators who are geologist and petroleum engineers, each with more than 10 years of experience in reservoir characterization, field development, estimation and reporting of reserves and who support the professionals involved in the estimation and reporting process.

 

  28  

 

 

Reserves are first estimated internally, supervised and coordinated by the Manager of Reservoirs, a geologist who holds a Master’s degree in geology and has more than 20 years of experience in projects associated with reservoir characterization and development, estimation, and reporting of reserves. The employees involved in the reserves process meet the Society of Petroleum Engineers qualifications for reserves estimators. Internally estimated reserves are submitted to an external audit process, which was conducted by the external engineers (Ryder Scott and DeGolyer and MacNaughton). According to our corporate policy, we report the reserves values obtained from the external engineers, even if they are lower than our internal estimated reserves.

 

The reserves estimation process ends when the Corporate Reserves Manager consolidates the results and together, with the Technical Vice-President, presents the outcome to the Reserves Committee, which comprises the CEO, Vice-President of Development and Production, Chief Financial Officer and the Upstream Chief Financial Officer. Results are later presented to the Audit and Risk Committee of the Board of Directors and finally approved by the Board of Directors.

 

Petroleum engineering consultants DeGolyer and MacNaughton and Ryder Scott have audited Ecopetrol’s proved reserves as of December 31, 2017. These external engineers audited 99% of our estimated net proved reserves. The reserves reports of the external engineers are included as exhibits to this annual report. The external engineers DeGolyer and MacNaughton and Ryder Scott audited 99% of our estimated net proved reserves for the year ended December 31, 2017, 2016 and 2015.

 

Ecopetrol uses deterministic methods that are commonly used internationally to estimate reserves. These methods have some uncertainty with respect to degradation, and thus, the estimates should not be interpreted as being exact amounts. However, the technology used to estimate reserves is considered reliable. The majority of the producing proved reserves were estimated by applying appropriate decline curves or other performance relationships. In analyzing decline curves, reserves were estimated by calculating economic limits that are based on current economic conditions. In certain cases, where the methods previously employed could not be used, reserves were estimated by analogy with similar reserves for which more complete data was available.

 

Estimates of reserves were prepared by geological and engineering standard methods commonly used in the oil and gas industry. The method or combination of methods used in the analysis of each reserve was adopted from experience analogy reserves, including information on the stage of development, quality and completeness of basic data and production history.

 

The following table reflects the estimated proved reserves of oil and gas as of December 31, 2015 through 2017, and the changes therein.

3.4.4        Joint Venture and Other Contractual Arrangements

 

We conduct our exploration and production business through a variety of types of contractual arrangements with the Colombian government or with third parties. Below is a general description of each type of contractual arrangement to which we were a party as of December 31, 2017:

 

Association Contract

 

The purpose of this type of contract, created by the Decree 2310 of 1974, is the exploration of the areas covered by the contract, and the exploitation of hydrocarbons found in that area. This type of contract, together with E&P contracts and Special Contracts (Casabe and La Cira) which are described below, are the most significant in terms of our production and proved reserves.

 

Under association contracts, the exploratory risk is assumed entirely by Ecopetrol S.A.’s contractual partner, the associate. If there is a discovery and Ecopetrol S.A. agrees that the relevant field is commercially viable, Ecopetrol S.A. will participate in the field’s development. A joint account will be created and Ecopetrol S.A. and the partner will participate in the expenses and investments in the proportions established in the corresponding contract. Ecopetrol S.A. will reimburse the direct exploratory expenses incurred by the contractual partner in the proportions established by the contract.

 

If Ecopetrol S.A. does not believe that the relevant field is commercially viable, the partner has the right to execute on its own all activities considered necessary for the field’s exploitation as a “sole risk operation”, and to be reimbursed for a defined percentage of all investments for such sole risk operation in accordance with the corresponding contract.

 

Every association contract provides for an executive committee that makes all technical, financial and operational decisions if Ecopetrol S.A. has agreed that a field is economically viable. All major decisions of this committee must be made unanimously by the parties.

 

The maximum term of an association contract is 28 years. The first six years of the contract are for the exploratory phase, and are extendible for 1 or 2 more years at the partner’s request. The remaining time is for the exploitation phase.

 

Incremental Production Contract

 

We enter into incremental production contracts to obtain incremental hydrocarbon production beyond a base production curve that is established based on the proven reserves of a specific field or well. Under this type of arrangement, Ecopetrol S.A. owns 100% of the hydrocarbons defined by the base production curve. The incremental production (i.e. the hydrocarbon volume obtained beyond the basic production as a result of investment activities), will be owned by the parties to such incremental production contract in the proportions established by such contract.

 

The initial phase of an incremental production contract has a term of up to 3 years, in which the contractual partner executes an initial work program approved by Ecopetrol S.A. in order to gain the right (but not the obligation) to continue with the second phase. If Ecopetrol’s partner decides to continue with the project for the second phase (the complementary phase), it must inform Ecopetrol S.A. in writing no later than 90 days prior to the termination date of the initial phase and deliver a proposed development plan for each covered field. The second phase is the production phase and has a maximum term of 22 years minus the length of the initial phase.

 

Incremental production contracts provide for an executive committee that is responsible for taking all decisions in order to approve, control, and supervise all operations that take place during the duration of the contract. These contracts also provide for a steering committee, which is responsible for the supervision of the execution of the work programs, the annual budget, and other items.

 

  30  

 

 

Risk Production Contract for Discovered Undeveloped and Inactive Fields (First Round 2003)

 

We have entered into risk production contracts for discovered undeveloped fields to promote exploration by private companies of both undeveloped and inactive fields. Under these contracts, the contracting party assumes all costs and expenses for the development and operation of a field in exchange for a percentage interest in the field’s production as specified in the contract. This type of contract has a ten-year term calculated as from its date of execution; one year for the evaluation period and a maximum of nine years for the development period. Some of these contracts have subsequently been extended beyond their original term.

 

Operation for Risk Production Contracts for Discovered Undeveloped and Inactive Fields (Second Round 2005)

 

The contracts awarded in the second round of undeveloped and inactive discovered fields are service contracts wherein services rendered are payable with a percentage of the production. Ecopetrol S.A. keeps all rights to explore and exploit hydrocarbons found in the area.

 

These contracts have a 10 year term, including an evaluation period of 8 months, within which the operator has to comply with a minimum commitment to conduct a technical evaluation of the field at its own risk.

 

Other than facilities associated with drilled wells, the facilities built during the term of the contract will be owned by the operator, who will remain responsible for them, even after contract ends. Only drilled wells become property of Ecopetrol S.A. upon the contract’s termination.

 

Risk Participation Contract

 

The purpose of this contract is the exploration of the contracted area, and the exploitation of the oil found in the contracted area. Unlike in the association contract, Ecopetrol S.A. shares exploratory risks and costs with the contractual partner, the associate, together with the oil produced, in the proportions established by the contract.

 

Risk participation contracts provide for an executive committee which is created upon the execution of the contract.

 

These contracts have a 28 year term, including an exploratory period of six years (which period is extendible under certain contracts for one or two years), after which the exploitation period commences.

 

Special Contracts

 

We are party to a Joint Venture Contract for Exploration and Exploitation of “La Cira-Infantas” Area; and a Services and Technical Collaboration Contract for the “Casabe” field.

 

Joint Venture Contracts for Exploration and Exploitation of “La Cira-Infantas” Area and of “Teca-Cocorná” Area

 

These contracts between Ecopetrol S.A. and Occidental Andina LLC, executed on September 6, 2005 and June 24, 2014, respectively, have as their purpose, a joint collaboration between the parties with the goal of increasing the economic value of the La Cira-Infantas field and the Teca-Corcorná field by means of hydrocarbon exploration and production activities, including, among others, an incremental production project to improve the recovery factor, process optimization, and exploratory activities.

 

Ecopetrol S.A. partially assigned its exploratory and production rights in the Contracted Areas to Occidental Andina LLC. Ecopetrol S.A. provides financial resources and the preferential rights of use for the existing infrastructure in that zone and Occidental Andina LLC provides financial resources and the technical and operative experience in mature fields redevelopment projects and enhanced recovery technologies.

 

  31  

 

 

Ecopetrol S.A. is the operator under both Joint Venture Contracts, and on behalf of the parties is responsible for the conduction, execution and control, directly or via contractors, of the operational activities.

 

The La Cira-Infantas contract’s term is divided in three phases. The first phase lasts 180 days, the second 730 days and the third up to the economical limit.

 

The incremental production, after deduction of the royalties, is owned 52% by Ecopetrol S.A. and 48% by Occidental Andina LLC. These same percentages apply to the participation in the operational and direct expenses. Adjustments to the participations for the benefit of Ecopetrol S.A. will occur if there are high production levels or high prices.

 

The Teca-Cocorná contract’s term is divided in two phases. The first phase lasts three years, extendable for up to an additional year, the second 20 years counted as from the initiation for the second phase and will be reduced by the term of any extensions of the first phase.

 

The incremental production, after deduction of the royalties, is owned 60% by Ecopetrol S.A. and 40% by Occidental Andina LLC. These same percentages apply to the participation in the operational and direct expenses. Adjustments to the participations for the benefit of Ecopetrol S.A. will occur if there are high production levels and high prices.

 

Services and Technical Collaboration Contract “Casabe”

 

The purpose of the contract executed between Ecopetrol S.A. and Schlumberger Surenco S.A. on April 26, 2004, is the evaluation, design and execution of work programs specifically with the purpose of increasing the value in the Casabe field by means of hydrocarbon exploration and production activities to obtain incremental production, application of new technologies, application of techniques for deposits management and operational costs reduction. Ecopetrol S.A. is the operator and Schlumberger Surenco S.A. keeps the right of first option regarding the activities to be executed in the area of interest.

 

Both parties can invest in all the activities seeking to evaluate, obtain and incorporate incremental value in the area of interest. Such activities are developed directly by the parties or via contractors (Ecopetrol) or subcontractors (Schlumberger). Amounts expended pursuant to the contract are reimbursed depending on the incremental value (monthly valuation in US$ of the results obtained from the execution of the work programs) created through the contract and the activities executed thereunder.

 

Both Ecopetrol S.A. and Schlumberger Surenco S.A. commit to assume full responsibility for damages and/or losses suffered by their respective personnel and goods in development of the contract, regardless of the cause. The maximum authority is the Management Committee.

 

The contract had an initial term of 10 years, and was amended several times to include an additional term of six years for which a new business was structured.

 

The National Hydrocarbons Agency (ANH) and its Contracts

 

The National Hydrocarbon Agency (“ANH”) was created by Decree Law 1760 of 2003 and was given the authority to administer all national hydrocarbon reserves under contracts executed beginning on January 1, 2004. Decree Law 1760 of 2003 states, “The Empresa Colombiana de Petróleos, Ecopetrol, is split, its organic structure is modified, and the Agencia Nacional de Hidrocarburos and the Sociedad Promotora de Energía de Colombia S.A. are created”. Prior to January 1, 2004, Ecopetrol S.A. had the authority to contract with third parties for the exploration and production of new areas.

 

The creation of the ANH did not modify the rights or obligations of Ecopetrol or other parties with respect to contracts in existence before January 1, 2004 when the ANH was created and therefore Ecopetrol retains the authority to execute agreements with respect to all areas that it held prior to that date.

 

  32  

 

 

Below, we include a brief description of each type of contract that we have entered into with the ANH:

 

Technical Evaluation Agreement

 

This type of contract grants to the contractor the right to develop technical evaluation operations with operational autonomy at its own cost and risk, seeking to appraise the hydrocarbon potential, with the purpose of identifying the zones of prospective interest in the area by means of the execution of an exploratory program. The contractor has the option to request the conversion of a technical evaluation agreement (“Technical Evaluation Agreement” or “TEA”) into one or more E&P Contracts that cover the area of the TEA (or a portion thereof).

 

The contractor can conduct evaluation activities for terms that vary between 18, 24 and 36 months, depending on the terms of reference of the ANH’s bidding round.

 

E&P Contract

 

The ANH enters into concession contracts pursuant to which the Nation grants exploration and production rights, and receives royalties and taxes. In turn, the contractor provides 100% of the investment and expenses resources, and receives 100% of the production after royalties and taxes. The ANH has named this contract an “Exploration and Production Contract” (E&P Contract).

 

Pursuant to the first stage of this contractual model, the ANH only receives a percentage of oil revenues in two cases:

 

(i) When the international oil prices rise beyond a specified price, above which the ANH has a right to participate in a share of the increased revenues generated, or

 

(ii) In the case of recognition of production rights in an extended contractual phase.

 

Under all E&P contracts executed since ANH’s 2008 bidding round, the ANH receives a percentage of the production from the beginning of the contract, upon the commencement of the production phase, and not only in the extension phase of the contract as mentioned in the previous paragraph. In addition, ANH has economic rights when the price of oil exceeds a reference price set in the contract (high price fee) and the superficiary canon.

 

E&P contracts have two phases: (i) an exploration period, which term is 6 years counted from the effective date, renewable for two additional years, and (ii) a production period, which is, with respect to each production field, 24 years plus any extensions, which are counted from the date of declaration of commerciality of the corresponding field. The above-mentioned terms have been modified during ANH’s 2014 bidding round for unconventional and offshore reservoirs to an exploration period of nine years and a 30 years production period.

 

ANH and Ecopetrol Agreements (Convenios)

 

At the time of termination or extension of any association contract executed by Ecopetrol S.A. before December 31, 2003, the rights over the production area and over the movable and immovable assets therein will continue to belong to Ecopetrol S.A.

 

Pursuant to article 2 of Decree 2288 of 2004, which regulates Decree Law 1760 of 2003, Ecopetrol S.A. must execute an agreement with the ANH to regulate the exploration and exploitation terms and conditions of the relevant area, which was previously subject to an association contract.

 

Decree 2288 of 2004 also established that Ecopetrol S.A. would have to execute agreements with ANH covering fields directly operated by Ecopetrol S.A. Under these agreements ANH recognizes the exclusive right of Ecopetrol S.A. to explore and exploit the hydrocarbons property of the Nation that are obtained in the areas they cover, until resource depletion or until Ecopetrol S.A. returns the area to the Nation through the ANH.

 

  33  

 

 

These agreements also provide the conditions under which Ecopetrol S.A. is able to assign, partially or completely, its rights and duties thereunder to third parties.

 

3.5        Transportation and Logistics

 

3.5.1.1        Transportation Activities

 

The transportation and logistics segment includes the transportation of crude oil, motor fuels, fuel oil and other refined products including diesel, jet and biofuels. We conduct most of these activities through our wholly-owned subsidiary Cenit and its subsidiaries.

 

The map below shows the locations of the main transportation networks owned by our business partners and us.

  34  

 

 

Graph 6 – Map of Multipurpose Pipeline

 

 

 

The table below sets forth the volumes of crude oil and refined products transported through the crude oil pipelines and multipurpose pipelines owned by us.

 

Table 32 – Volumes of Crude Oil and Refined Products Transported

 

    For the year ended December 31,  
    2017     2016     2015  
    (thousand bpd)  
Crude oil transport (1)     823.3       867.0       978.0  
Refined products transport (2)     268.2       263.1       253.8  
Total     1,091.5       1,130.1       1,231.8  

 

 

(1) The crude oil transported volumes correspond to the following systems: Ocensa Segment 3, ODC, Vasconia-Galan, Ayacucho-Galan, Ayacucho-Coveñas and Trasandino Pipeline.
(2) The pipelines transporting refined products include the following: Galan-Sebastopol, Galan-Salgar, Galan-Bucaramanga, Buenaventura-Yumbo and Cartagena-Baranoa.

 

The volume of crude oil transported by Cenit´s main systems and those of affiliates decreased in 2017 by 5% compared to the previous year. This decrease was mainly the result of attacks on the Caño Limon – Coveñas pipeline causing that pipeline to be out of operation for 193 days. Additionally, we experienced a decrease in the volume of crude oil transported out of the Oleoducto Trasandino (“OTA”) pipeline. Of the total volume of crude transported by oil pipeline, approximately 60% belonged to Ecopetrol’s corporate group.

 

The volume of refined products transported by Cenit increased by 1.9% in 2017 mainly due to growth of local fuel demand. This increase was partially offset by operating conditions such as, among others, an increase in inventories of certain customers, and the presence of illicit valves in the Oriente pipelines. Of the total volume of refined products transported in multi-purpose pipelines during the year, 23% belonged to Ecopetrol’s corporate group.

 

  35  

 

 

Transportation Capacity

 

During 2017, we increased the capacity of our primary and secondary oil pipelines and loading facilities due to the expansion of Ocensa's capacity, which in turn was due to the commencement of project P135 that contemplated the repowering of the entire system including the entry of three new pumping stations in segments two and three. Our main crude oil pipeline systems’ operating capacity increased from 1,369,000 bpd in 2016 to 1,500,000 bpd in 2017.

 

Our main refined products pipeline transportation capacity increased from 515 thousand bpd in 2016 to 518.6 thousand bpd in 2017. This increase in capacity was primarily the result of a new validation of the capacities of some of our pipelines with drag reducing agents.

 

References to our crude oil transportation capacity in this annual report refer to the capacity of the pipelines that belong to Cenit and its subsidiaries to transport crude oil volumes either to the Barrancabermeja refinery or to our export facilities. In addition, we have other feeder systems that transport oil volumes from producing facilities or other pumping stations to these main pipelines. References to our refined products transportation capacity refer to the capacity of pipelines that begin in the Galan station (Barranca refinery) and Cartagena station (Cartagena refinery).

 

3.5.1.2        Pipelines

 

As of December 31, 2017, we, directly or indirectly with private partners, own, operate and maintain an extensive network of crude oil and refined products pipelines. These pipelines connect our own and third-party production centers, import facilities and terminals to refineries, major distribution points and export facilities in Colombia. Cenit directly owns 45% of the total crude oil pipeline shipping capacity in Colombia. When aggregated with the crude oil pipelines in which Cenit owns an interest, Cenit owns 82% of the oil pipeline shipping capacity in Colombia. By December 31, 2017, our network of crude oil and multipurpose pipelines was approximately 8,939 kilometers in length. The transportation network consists of approximately 5,228 kilometers of main crude terminals and oil pipeline networks connecting various fields to the Barrancabermeja refinery and Reficar, as well as to export facilities. We also own 3,712 kilometers of multipurpose pipelines for transportation of refined products from the Barrancabermeja refinery and from Reficar to major distribution points. Out of the 5,228 kilometers of crude oil pipelines, owned by us, 3,016 kilometers of crude oil pipeline are wholly owned and 2,212 kilometers of crude oil pipeline are owned through non-wholly owned subsidiaries.

 

The following table sets forth our main pipelines in which we own an indirect interest as of December 31, 2017.

(1) Transportation capacity for this pipeline is measured by using crude oil viscosity of 690 cStk (30° C).
(2) Represents the contractual crude oil transportation capacity for the pipeline currently in operation.

 

As of December 31, 2017 we owned 72 stations, 38 located in crude oil pipelines, 30 in refined products pipelines, 2 in crude oil ports and 2 in refined product ports.

 

  36  

 

 

As of December 31, 2017, we had a nominal storage capacity associated with the transportation network of 17.6 million barrels of crude oil and 4.4 million barrels of refined products. We do not own any tankers.

 

The Transportation and Logistic segment implemented a new maintenance operating model with the aim of clarifying roles as well as unifying criteria for planning and execution among the companies of the segment.

 

Pipeline Projects SAN FERNANDO – MONTERREY

 

The San Fernando – the Monterrey project’s initial objectives included ensuring the ability to transport 300,000 bpd at 300cSt of diluted crude oil from the Chichimene and Castilla fields to the Monterrey pumping station and the transportation of 45,000 bpd of diluent (naphtha) between the Apiay station and the Castilla and Chichimene fields.

 

The scope of the project includes the construction of a new 30” 119 km crude oil pipeline, a new pumping station to include reception, storage and dilution facilities, the conversion of the existing pipeline of 10” between the Castilla II plant and the Apiay station, and the construction of a new 10” pipeline between Chichimene and San Fernando fields in order to transport diluent (naphtha) from the Apiay station to the San Fernando plant.

 

During 2017, the systems and subsystems were tested and started to operate according to the defined operational requirements. Currently, the pipeline is operating above 650 cSt.

 

OLEODUCTO AL PACIFICO SAS

 

Given the uncertainties around the future results of the exploration and production activities in Colombia and the current expected return of the investment, in December 2017 the parties engaged in the Oleoducto al Pacifico suspended the project. Based on our current view, this decision has had no impact on the oil industry in Colombia and can be reconsidered in the event the transportation system may be necessary.

 

TRANSPORTATION OF HIGHER VISCOSITY CRUDES

 

Ocensa executed an ambitious plan that addressed the crude oil basket quality in Colombia, where oil production is mainly comprised of heavy crude oil. In response, Ocensa offered a solution to its clients by developing the AD600 project that leveraged transportation from 300 cSt to 600 cSt. Since March 2017 the Ocensa pipeline regularly operates with this new viscosity specification with normal operational conditions that satisfy our clients’ needs.

 

Adaptations were also made to one of the single buoy moorings of the Coveñas terminal to permit the import of naphtha for dilution at this terminal. Integral capacity tests were executed in March 2017 for the transport of crude with this viscosity, and transport began in the same month.

 

The main modifications are on: the ODL pipeline (Oleoducto de los Llanos; Rubiales – Cusiana), on Ocensa Segment 1 (Cusiana – Porvenir), Segments 2 & 3 (El Porvenir – Vasconia – Coveñas) and on the Oleoducto de Colombia Pipeline (ODC – Oleoducto de Colombia). This project, combined with the expansion of capacity on Ocensa (P-135), will make it possible to transport higher viscosity crudes.

 

3.5.1.3        Export and Import Facilities

 

We currently have concessions granted by the Nation for four export/import docks for crude oil and refined products: Coveñas, Tumaco, Pozos Colorados and Cartagena. Our export capacity reached 1.24 million bpd for crude oil. Our import capacity of refined products reached 0.18 million bpd.

 

Our crude oil loading facilities can load tankers of up to 350 thousand deadweight tonnage (DWT). Adjacent to these loading facilities we also have crude oil storage facilities that are capable of storing 9 million barrels. Our docks used for import and export of refined products can load tankers of 70 thousand DWT. Additionally, these facilities have storage capacity of up to 1.2 million barrels.

 

  37  

 

 

3.5.2        Other Transportation Facilities

 

We have entered into transportation agreements with tanker-truck and barge companies in order to transport crude oil from locations that do not have pipeline connections to refineries and export facilities. The volume of refined products that cannot be transported in pipelines or in tanker trucks because of capacity limitation is transported by barges. During 2017, 24.8 million barrels of crude oil and refined products were transported by tanker trucks and 8.98 million barrels of crude oil and refined products were transported by barges, particularly using the Rio Magdalena, connecting Barrancabermeja with Barranquilla and Cartagena.

 

3.5.3        Marketing of Transportation Services

 

Cenit and its subsidiaries’ main line of business is the crude oil pipeline transport (74% of revenues), followed by the refined products pipeline transport (17% of revenues) and ports and related services (7% of revenues).

 

Transportation contracts of crude oil may take several forms: ship or pay (payment for the availability of a fixed capacity in the system), ship and pay (payment for volumes actually transported) or spot. The main users for the crude oil transportation business are Ecopetrol S.A., Metapetroleum Corp., Petrominerales, Occidental de Colombia, Mansarovar and Gran Tierra, who collectively represented 93% of this business segment’s revenues in 2017. Transportation services for crude oil provided to Ecopetrol S.A. represented 54% of this business segment’s crude oil transport revenues.

 

Cenit also transports refined products. Its main client for this service is Ecopetrol S.A., which accounted for 42% of refined products pipeline transport revenues in 2017, principally due to the transport of naphtha, diesel and gasoline. Cenit also has 13 other fuel wholesalers’ customers for whom it transports other refined products. The most significant of these customers are Organizacion Terpel, ExxonMobil, Chevron Petroleum Company, Biocombustibles S.A.S. and Petrobras Colombia.

 

Deregulated businesses such as ports and crude loading facilities represent a smaller portion of Cenit’s revenue (7% in 2017). Clients for these businesses include some of the same parties for which Cenit provides crude oil and refined products transportation services.

 

3.6        Refining and Petrochemicals

 

3.6.1        Refining

 

Our main refineries are the Barrancabermeja refinery, which Ecopetrol S.A. directly owns and operates, and a refinery in the Free Trade Zone in Cartagena that is operated by Reficar S.A., a wholly owned subsidiary of Ecopetrol S.A., Ecopetrol S.A. also owns and operates two other minor refineries – Orito and Apiay, but these are considered part of the upstream segment since the majority of production is for self-consumption.

 

Our refineries produce a full range of refined products, including gasoline, diesel, jet fuel, LPG, and heavy fuel oils, among others.

(1) Reficar’s operations were fully stabilized during the second half of 2017.
(2) Apiay and Orito are considered to be part of the upstream segment, not the refining segment, and the majority of products are for local on-site consumption.
(3) The capacity indicated in 2015 was 165 thousand barrels per day which includes a design safety factor of 10%.

 

3.6.1.1        Barrancabermeja Refinery

 

The Barrancabermeja refinery supplies 55% of the fuels consumed in Colombia according to internal calculations made by the Barrancabermeja refinery and Colombia´s fuels consumption reported by the Ministry of Finance.

 

The following table sets forth the production of refined products of Barrancabermeja for the periods indicated.

Total Production     212,515       214,178       220,713  

 

In 2017, total production from the Barrancabermeja refinery decreased by 0.8% from 214,178 bpd in 2016 to 212,515 bpd in 2017 primarily due to lower throughput caused by less feedstock of light and intermediate crudes, which in turn was consequence of insurgent actions on the Caño Limon-Coveñas pipeline.

 

We own and operate four petrochemical plants and one paraffin and lube plant located within the Barrancabermeja refinery. In 2017, we produced 53,417 tons of low-density polyethylene, a decrease of 4% compared to the production of 55,642 tons in 2016. This decrease was due primarily to a reduction in the operational availability of the turboexpander unit. We produced 857 kboepd of aromatics (benzene, toluene, xylene, orthoxylene, heavy aromatics and cyclohexane), a 57% decrease as compared with the production of 1,994 kboepd of aromatics in 2016. The decrease was mainly the result of lower load and availability of light crude oils (particularly from the Caño Limon pipeline) as explained above.

 

  39  

 

 

The gross refining margin decreased from US$14 per barrel in 2016 to US$13.5 per barrel in 2017, primarily due to price differentials of refined products as compared to crude oil, in line with international market trends, and the increase in the local crude price by US$6 per barrel in 2017 as compared to 2016.

 

The average conversion ratio for Barrancabermeja refinery was 82.7% in 2017 and 74.6% in 2016. This increase in the conversion ratio was primarily due to an increase in the yield of medium distillates and a decrease in the production of fuel oil by redirecting efforts to higher-value currents.

During its stabilization period in the second half of 2017, Reficar reached the goal of completing individual unit performance tests (for 100% of units), and the Global Performance Test on December 5, 2017. During the Global Performance Test, Reficar maintained an average throughput of 144 thousand barrels per day for 60 days.

 

In terms of gross refining margin, the refinery progressed from an average of approximately to US$5.3 per barrel in 2016 to US$9.5 per barrel in 2017. Throughput also improved during 2017, increasing from an average of 117 kbpd in 2016 to 136 kbpd in 2017.

 

Reficar’s 2017 financials already reflect the operation of the new units, thus total sales have increased 44% as compared to 2016, from US$2,142 million in 2016 to US$3,085 million in 2017. A total of 49.5 million barrels of crude were processed in 2017 compared to 42.9 million barrels processed in 2016. Exports to international markets represented 36% of total sales (US$ 1,111 million). During 2017, the refinery’s production has substituted 1.6 million barrels of gasoline and 8.8 million barrels of diesel, which previously had to be imported in order to supply the domestic demand. As per information provided by the Colombian Government (specifically by the National Statistics Department –DANE-), Reficar and Barrancabermeja contributed 0.9 percentage points to the National Industrial GDP growth for 2017.

 

Financing

 

On December 30, 2011, with the approval from the Colombian Ministry of Finance and Public Credit, Reficar executed a US$3.5 billion project finance to partially fund the expansion and modernization of the refinery in Cartagena, loans with tenors of 14 and 16 years from Commercial Banks and Export Credit Agency Facilities, respectively. The aggregate amount drawn under these finance agreements totaled US$3,496.6 million. These credit agreements included a mechanism by which Reficar can exit the facility by transferring the debt to the Ecopetrol parent level by either (i) the occurrence of a mandatory debt assumption event or (ii) a voluntary debt assumption. As part of Ecopetrol Group’s strategy to optimize its capital structure, on December 13, 2017, with the approval of the senior lenders and the Colombian Ministry of Finance and Public Credit, Ecopetrol S.A. voluntarily assumed Reficar’s senior debt. The principal amount repaid by Reficar during 2016 was US$269 million and during 2017 was US$130 million. Interest payments during 2016 and 2017 were US$87 million and US$42 million, respectively. As of the date of the voluntary assumption, Reficar owed the senior lenders a principal amount of US$2,666 million (in nominal terms).

 

As a result, debt service paid by Reficar during 2017 was lower as compared to 2016 because Ecopetrol assumed the debt service payment due on December 20, 2017, as described above.

 

During 2017, Reficar received capital injections of US$269 million to cover project capital expenditures, start-up costs, one-off stabilization costs of the new refinery and the debt service payments due on June 20, 2017. The amount requested by Reficar under the Construction Support Agreement was US$97 million. The amount requested by Reficar under the Debt Service Guarantee Agreement was US$172 million. There was no need to request additional contributions under the Debt Service Guarantee to cover the debt service payment due on December 2017. Total debt service payments during 2017 totaled US$172 million.

 

  41  

 

 

In order to finalize the implementation of Ecopetrol Group’s strategy to optimize its capital structure, the following capital injections were undertaken by Ecopetrol on December 13, 2017, increasing its shareholding participation in Reficar from 46.58% to 75.96%:

 

· As a result of the voluntary debt assumption, Reficar assumed an account payable in the amount of US$2,596 million (book value for Reficar’s senior debt under IFRS) in favor of Ecopetrol. As a shareholder, Ecopetrol requested that such account be repaid with Reficar shares.

 

· Ecopetrol requested that the existing subordinated COP-denominated loan it granted in Reficar in the amount of $1,522,760 million (book value as of December 13, 2017) be repaid with new Reficar shares.

 

3.6.1.3        Polipropileno del Caribe S.A.

 

During 2017, Propilco production totaled 441 thousand tons of petrochemical products, a 0.9% decrease compared to the 445 thousand tons produced in 2016, due to feedstock price volatility. The total contribution margin in 2017 (including the contribution of polypropylene, polyethylene and masterbatches) was 32% lower than in 2016, a decrease from US$318 per ton in 2016 to US$215 per ton in 2017. The decrease in contribution margin was primarily due to higher volatility in the propylene market, Propilco’s main feedstock.

We have investments in two biofuels companies: (i) Bioenergy S.A.S., in which we own 99.08 % of the shares, who finished the construction of an ethanol plant with theoretical capacity of 480,000 liters / day, and (ii) Ecodiesel Colombia S.A., in which we own 50% of the shares, currently in operations with a theoretical capacity of 100,000 tons per year of biodiesel.

 

3.6.2        Marketing and Supply of Refined Products

 

We are the main producer and supplier of refined products in Colombia. We market a full range of refined and feedstock products including regular and high-octane gasoline, diesel fuel, jet fuel, natural gas and petrochemical products, among others.

 

3.7        Research and Development; Intellectual Property

 

Our innovation and technology center is the Colombian Petroleum Institute, established in 1985 and located in Bucaramanga, Santander. In 2017, research and development expenses were US$25.7 million, compared to US$16.9 million in 2016. Technology and innovation are essential to our efforts to add value to our business segments through the development of proprietary technologies and competitive advantages and the adaptation of third-party technologies to our processes.

 

The focus of technology development is on designing high added-value products and solutions for Ecopetrol and the Colombian oil industry. The scope of the Colombian Petroleum Institute activities covers all of our value chain segments: exploration, production, refining, transportation and commercialization, as well as environmental sustainability and asset integrity.

 

Each year Ecopetrol presents to the Colombian Institute for the Development of Science and Technology ( Instituto Colombiano para el Desarrollo de la Ciencia y la Tecnología , or COLCIENCIAS) its research, technology development projects and innovation initiatives, in order to obtain certifications for its science and technology investments. COLCIENCIAS certifies science and technology investments, which are deductible from income tax upon execution; and Ecopetrol applies the tax benefit. In 2017, we obtained US$12.3 million in science and technology-related tax benefits certified by COLCIENCIAS.

 

  42  

 

 

Our intangible assets are preserved through a technological value-generation process and an intellectual property protection process, which include the consolidation of trade secrets, patents, copyrights, trademarks, industrial designs, and publications in specialized journals. Ecopetrol has filed 207 patent applications in the last ten years, 12 of them in 2017. Our most recent patent applications include innovative technologies such as (i) a process to improve the flow capacity and enhance the dilution capacity of diluents in heavy and extra-heavy oil production and transport processes, (ii) equipment for the evaluation of electrochemical impedance at high temperatures, (iii) a clay-based catalyst for hydrocracking processes, (iv) catalysts for hydrotreating naptha and (v) a process and equipment for the pretreatment and saccharification of biomass.

 

In 2017, Ecopetrol declared four industrial secrets that strengthen its competitive advantages in exploration, refining and transport of heavy crudes in Colombian basins. The Colombian and international authorities granted us five new patents, including one in Brazil that protects our proprietary process to obtain bioparaffins through hydrotreatment of oils. We currently hold 84 patents in Colombia, the United States, Mexico, Russia, Peru, Venezuela, Ecuador, Brazil, Nigeria, Indonesia, and Malaysia.

 

In 2017, Ecopetrol S.A. licensed 10 of its technologies to private companies for manufacturing, marketing commercialization, and after-sales support. To date, we have licensed 42 technologies to Colombian and multi-national companies. One of the licensed technologies is a system of chemical additives to reduce the consumption of diluent in heavy crude oil gathering and dehydration. Another licensed technology reduces haze in biodiesel. Some of our technologies have potential uses in other industries, and may in the future represent an important source of income.

 

3.8        Applicable Laws and Regulations

 

3.8.1        Regulation of Exploration and Production Activities

 

3.8.1.1        Business Regulation

 

Pursuant to the Colombian Constitution, the Nation is the exclusive owner of all hydrocarbon resources located in Colombia and has full authority to determine the rights to be held and royalties or compensation to be paid by investors for the exploration or production of any hydrocarbon reserves. The Ministry of Mines and Energy and the ANH are the authorities responsible for regulating all activities related to the exploration and production of hydrocarbons in Colombia.

 

Decree Law 1056 of 1953 (the Petroleum Code, or Código de Petróleos ) declares that the hydrocarbon industry and its activities of exploration, exploitation, refinement, transportation and distribution are of public interest, which means that, in the interest of the hydrocarbon industry, the Colombian government may order necessary expropriations in order to develop such industry. The hydrocarbon industry is under governmental supervision and control, regulated mainly by the Ministry of Mines and Energy and the ANH.

 

Ministry of Mines and Energy Resolution 181495 of 2009, as amended by Resolution 40048 of 2015, establishes a series of regulations regarding hydrocarbon exploration and production.

 

Ministry of Mines and Energy Resolution 180742 of 2012, partially repealed by Resolution 90341 of 2014, included a series of technical regulations for unconventional hydrocarbon resources, including the procedures for advancing the exploration and exploitation of unconventional reserves. It also establishes the types of wells and their classification as well as the fulfillment of those minimum (drilling and abandoning) conditions, necessary to initiate or perform E&P activities. Furthermore, it contemplates the applicable procedure to resolve disputes between mining sector and the oil and gas sector, regarding the coexistence of their rights in some specific projects.

 

On May 26, 2015, Decree 1073 compiled the majority of Colombian decrees in force regarding the administrative sector of mines and energy.

 

  43  

 

 

Agreement ( Acuerdo , a type of regulation) 004 of 2012, as issued by the ANH, amends Agreement 008 of 2004 and sets forth the rules governing the award of exploration and production areas and the execution of contracts. As set forth below, Agreement 002 of 2017 replaces this Acuerdo.

 

Agreement 003 of 2014, as issued by the ANH, complements Agreement 004 of 2012 by setting forth the contractual framework for the carrying out of activities in unconventional reservoirs, the procurement regulations for the exploration and exploitation of unconventional fields and the procurement process for the awarding of hydrocarbon exploration and exploitation areas.

 

Agreement 002 of 2015, as issued by the ANH, partially amends Agreement 004 of 2012 and sets forth the initial rules and measures the Government can take to mitigate the adverse effects of the decline of international oil prices. The main measures established by this agreement are the following:

 

(i) The extension of terms and deadlines for the execution of activities related to investments in exploration and evaluation phases and for the declaration of commercial discoveries;

 

(ii) The establishment of procedures to transfer investments in exploration programs between allocated areas: and

 

(iii) The levelling of the contractual terms of offshore contracts entered before 2014 to the ones included in the contracts executed as a result of the 2014 Colombian Round.

 

Agreement 003 of 2015, as issued by the ANH, modifies and also partially amends Agreement 004 of 2012, and provides certain rules and measures the Government can take to mitigate the adverse effects of the decline of international oil prices. This agreement permits performance guarantees required under E&P contracts to be reduced in the same amount as the works actually performed during the term of the respective phase.

 

Agreement 004 of 2015, as issued by the ANH, also partially amends Agreement 004 of 2012, and provides certain rules and measures for the Government to mitigate the adverse effects of the decline of international oil prices. This agreement allows contractors to attribute additional activities carried out under a TEA to commitments under the first phase of an E&P contract.

 

Agreement 002 of 2017, as issued by the ANH on May 18, 2017, replaces Agreement 004 of 2012, Agreement 003 of 2014, and Agreements 002, 003, 004 and 005 of 2015. It establishes the general structure of the New Regulation for Administration and Assignment of Areas and the general guidelines regarding future hydrocarbon contracts in Colombia. Seeking the interests of the Nation, the market conditions, the national hydrocarbon sector strategy, the competitive context of producer countries and the Nation’s social and environmental evolution.

 

Agreement 002 of 2017 adapted the existing regulations for the selection of contractors, and the applicable rules for the award, execution, termination, liquidation, monitoring, control and surveillance of the contracts signed with the ANH.

 

3.8.1.1.1 Environmental Licensing and Prior Consultation

 

Law 99 of 1993 and other environmental regulations, such as particularly Decree 1076 of 2015 (compilation decree regarding the administrative sector of environment and sustainable development), impose on companies, including oil and gas companies, the obligation to obtain an environmental license prior to undertaking any activity that may result in the serious deterioration of renewable natural resources, or that may have the capacity of materially modifying the physical environment.

 

The National Authority on Environmental Licensing (ANLA), created by means of Decree 3573 of 2011, is the entity responsible for evaluating the applications and issuing the environmental licenses for oil & gas-related activities, as well as surveilling and overseeing all hydrocarbons projects and monitoring the environmental compliance of such activities.

 

  44  

 

 

If the projects or activities could have a direct impact over the territories or the interests of indigenous, Afro-Colombian or Raizal communities, the Colombian Constitution provides that the companies developing such projects or activities must undertake a public consultation process with those communities before initiating such projects or activities. This consultation process is a pre-requisite for obtaining the required environmental licenses.

 

In addition, the Colombian Constitution and laws establish that, as part of the public participation mechanisms, Colombian individuals may request information regarding the activities of the project and their potential impacts. They may also request to undertake an environmental hearing so as to obtain information of the project subject to environmental licensing.

 

On May 26, 2015, the Ministry of Environment and Sustainable Development (“MESD”) issued Decree 1076, which compiles the majority of Colombian regulations in force regarding environment and sustainable development.

 

The environmental license encompasses all of the necessary permits, authorizations, concessions and other control instruments necessary under Colombian environmental law to undertake a project or activity that may result in the serious deterioration of renewable natural resources, or that have the capacity of materially modifying the physical environment. The license shall define specific conditions under which the beneficiary of the license may undertake such project or activity. The procedure to obtain an environmental license begins when the company files an Environmental Impact Study (EIA) related to the project before the ANLA. The licensing process includes an application for the use of natural renewable resources (water, soil and air), the filing of an EIA and a plan to prevent, mitigate, correct and compensate for any activity that may harm the environment, known as the Environmental Management Plan (PMA).

 

The environmental licensing procedure in Colombia is set forth in Decree 1076 of 2015. According to the regulation currently in effect, the procedure to obtain an environmental license shall not take more than 90 business days. But, depending on the complexity of the information requested by the ANLA and administrative delays, including an oral hearing to determine the viability of the project, the procedure may take between 165 and 265 business days, depending on whether the applicant is required to file additional information. The new procedure incorporates an oral hearing between the ANLA and the applicant in order to evaluate the information provided in the license application and whether it is necessary or not to request additional information about the proposed project. The ANLA will have no other opportunities to request additional information after this hearing.

 

MESD is also responsible for establishing guidelines regarding climate change policies for the hydrocarbon sector in Colombia. We comply with those guidelines. At present, MESD has not proposed any specific steps for the implementation of the Kyoto Protocol or the Paris Agreement, as they relate to our operations. We are continuously monitoring climate change requirements that could be applicable to us. A company that does not comply with the applicable environmental laws and regulations, does not execute the Environmental Management Plan (PMA) approved by the environmental authority or ignores the requirements imposed by an environmental license may be subject to an administrative proceeding initiated by the ANLA or the regional environmental authorities established by Law 1333 of 2009. The proceeding may result in oral or written warnings, monetary penalties, fines, license revocation or the temporary or permanent suspension of the activity being undertaken. Apart from administrative sanctions, the Colombian judiciary or other law enforcement authorities may also impose civil and even criminal sanctions if environmental damages are verified as a consequence of having breached the environmental laws and regulations applicable to the project.

 

3.8.1.1.2 Royalties

 

In Colombia, the Nation is the owner of minerals and non-renewable resources located in the subsoil, including hydrocarbons. Thus, companies engaged in exploration and production of hydrocarbons, such as Ecopetrol, must pay to the National Hydrocarbons Agency (ANH), as representative of the National Government of Colombia, a royalty on the production volume of each production field, as determined by the ANH.

 

Royalties may be paid in kind or in cash. Each production contract has its applicable royalty arrangement in accordance with applicable law. In 1999, a modification to the royalty regime established a sliding scale for royalty payments for crude oil and natural gas production fields discovered after July 29, 1999 and depending on the quality of the crude oil produced. Since 2002, as a result of the enactment of Law 756 of 2002, the royalty rate was fixed as a sliding scale depending on the produced volume from 8% for fields producing up to 5 kbpd to 25% for fields producing in excess of 600 kbpd. Notwithstanding the royalties for Incremental Production Contracts, Contracts for Undeveloped and Inactive Fields, and Incremental Production Projects defined in paragraph 3 article 16 Law 756 of 2002, and article 29 of the law 1753 of 2015, the changes in the royalty regime only apply to new discoveries and do not apply to fields already in the production stage as of July 29, 1999. Producing fields pay royalties in accordance with the royalty law in force at the time of the discovery.

 

  45  

 

 

Regarding natural gas, in accordance with Resolution 877 of 2013, as amended by Resolution 640 of 2014, starting on January 1, 2014, the ANH has received royalties in cash rather than in kind. Thus, the producer may dispose of its gas production volumes corresponding to royalties paid in cash.

 

3.8.2        Regulation of Transportation Activities

 

Hydrocarbon transportation activity is a public interest activity in Colombia and a public service. As such, it is under governmental supervision and control, regulated mainly by the Ministry of Mines and Energy and CREG.

 

Transportation and distribution of crude oil, liquefied petroleum gas and refined products must comply with the Petroleum Code, the Code of Commerce and all governmental decrees and resolutions. However, liquefied petroleum gas related-activities are regulated by CREG. According to Law 681 of 2001, multipurpose pipelines owned by Cenit (a company wholly owned by Ecopetrol) must be open to third-party use on the basis of equal access to all.

 

Notwithstanding the general rules for hydrocarbon transportation in Colombia, Law 142 of 1994 defines the regulatory framework for the provision of public utility services, including the provision of natural gas. Moreover, natural gas transportation is subject to regulations specific to the natural gas industry as issued by CREG, due to the categorization of natural gas distribution as a public interest activity under Colombian laws.

 

Transportation systems, classified as crude oil pipelines and refined product pipelines, may be owned by private parties. Pipeline construction, operation and maintenance must comply with environmental, social, technical and economic requirements under national guidelines and international standards for the oil and gas industry.

 

Construction of transportation systems requires licenses and local permits awarded by the Ministry of Mines and Energy, the Ministry of Environment and Sustainable Development and regional environmental authorities, respectively.

 

Crude oil transport

 

The regulatory framework relating to crude oil transportation accounts for both private use and public use pipelines. Private use pipelines are those built by the operating or refining entity for its own exclusive right and that of its affiliates. Public access pipelines are defined as pipelines built and operated by a public or private legal entity, for the purpose of publicly providing crude oil transportation services. The Colombian government, through the ANH, has a preferential right to use up to 20% of the total capacity of any public or private access pipeline to transport its share of production. However, for both private and public access pipelines, the ANH must pay the tariff for the pipeline use to transport its percentage of production.

 

The Ministry of Mines and Energy is responsible for reviewing and approving the design of and tracks for crude oil pipelines, by establishing transport rates based on information provided by the service providers. It also oversees the calculation and payment of hydrocarbon transport-related taxes and manages the information system for the oil product distribution chain.

 

In 2014, the Ministry updated the transport regulation and the rate calculation method for this line of business. It introduced a framework for the secondary market and incentives for new pipeline construction and current pipeline capacity expansions. According to the Petroleum Code, rates must be revised every four years.

 

  46  

 

 

During the scheduled revision of 2015 and due to the dramatic changes in international crude oil prices, the Ministry of Mines and Energy allowed, by means of Resolution 31325 of 2015, transportation companies and oil production companies to engage in direct negotiations in order to agree on a tariff suitable for both parties. The negotiation period was extended until June 2016. Notwithstanding the fact that tariff agreements were reached with certain companies, the results of the negotiations were not positive. Thus, tariffs were set by the Ministry of Mines and Energy in accordance with the criteria previously established by Resolution 72146 of 2014, as further amended by Resolution 31325 of 2015 and Resolution 31285 of 2016.

 

The Port Superintendence is the authority that oversees the port business for crude oil and refined products. Although this business is not highly regulated, market participants are required to report certain information to the Port Superintendence.

 

As a result of the enactment of Decree 119 of 2015, operators of private use hydrocarbon ports are currently able to provide hydrocarbon transport services to third parties pursuant to a mechanism established under that decree.

 

Decree 119 of 2015 was incorporated into Decree 1079 of 2015 issued by the Ministry of Transport, which compiles the majority of Colombian decrees and regulations in force regarding the administrative sector of transportation.

 

Refined products and liquefied petroleum gas transport

 

In 2014 CREG assumed responsibility for regulating product pipeline transportation from the Ministry of Mines and Energy, in addition to its pre-existing regulatory responsibility for liquefied petroleum gas, natural gas and electric energy transportation.

 

In August 2017 CREG issued a draft resolution 113 of 2017, which introduced a new framework for the transportation regulation of liquefied petroleum gas and refined products. The draft resolution is currently open for observations from the general public and the oil and gas industry. CREG is also in the process of defining the transportation regulation and the rate calculation method for refined products. The primary goals and components of the proposed regulation are: a) to ensure access to the transport systems for liquid fuels and the LPG pipeline systems without discrimination; b) to promote the timely expansion of the transport system in line with the needs of the market; c) to promote competition and prevent restrictive practices; d) to separate the operations of refining and transport; and e) to ensure the efficient and continuous operation of transport systems.

 

3.8.3        Regulation of Refining and Petrochemical Activities

 

Article 58 of the Petroleum Code establishes that oil refining activities can be developed throughout the Colombian territory and are not reserved to the State. However, Article 4 establishes that such activities are considered of public interest subject to governmental regulation, and the development of those activities must comply with technical requirements established by regulation.

 

In 2008, Law 1205, further developed by Resolution 180689 of 2010, issued by the Ministry of Mines and Energy, was issued with the main purpose of contributing to a cleaner environment. It established the minimum quality specifications for fuels in Colombia. Since August 2010, Ecopetrol has been producing and selling diesel and gasoline that complies with the requirements of the aforementioned law and, for some cities, we sell with better standards.

 

Since 1995, under Resolution number 898 of August 23, 1995 the Ministries of Environment and Sustainable Development and of Mines and Energy, have regulated the environmental criteria for liquid and solid fuels used in commercial and industrial furnaces and boilers as well as automobile internal combustion engines. Resolution 898 has been subject to numerous modifications through the years, the most recent by Resolution 40619 of June 30, 2017. Ecopetrol has been complying with this regulation and working with governmental entities in order to improve air quality in the most critical areas in Colombia.

 

  47  

 

 

3.8.3.1        Regulation of Liquefied Petroleum Gas (LPG) and Liquid Fuels

 

Wholesale marketing, transport, distribution and retail marketing of LPG are mainly regulated by CREG Resolution 74 of 1996, and subsequent resolutions. LPG in Colombia is primarily obtained through Ecopetrol’s refineries, field production and imports. The LPG must meet minimum quality standards to be marketed. Our marketing activities are regulated by CREG Resolution 53 of 2011 (as amended by CREG Resolutions 108 of 2011, 154 of 2014, 019 of 2015, and 034, 063 and 064 of 2016). The LPG price is regulated by CREG Resolutions 66 of 2007 (as amended by CREG Resolutions 59 of 2008, 002 of 2009, 123 of 2010, 095 of 2011, 65 and 129 of 2016).

 

According to Article 4 and 212 of the Petroleum Code and Law 39 of 1987 (added by Law 26 of 1989), the distribution of crude oil and its derivatives has a public purpose ( utilidad pública ), and the distribution of fuel oil and crude oil by-products is considered a public utility activity. Consequently, individuals or entities engaged in these activities are subject to regulations issued by the Colombian government. The Government has the power to determine quality standards, measurement and control of liquid fuels, and establish penalties that may apply to dealers who do not operate in compliance therewith.

 

The Ministry of Mines and Energy is the entity that controls and exercises technical supervision over the distribution of liquid fuels derived from petroleum, including the refining, import, storage, transportation and distribution in the country. Law 812 of 2003 identified the agents of the supply chain of petroleum-based liquid fuels. In this context, The Ministry of Mines and Energy through Resolution 40344 of 2017, published the required actions to ensure the LPG supply for the priority sectors in the country.

 

The distribution of liquid fuels, except LPG, is governed by Decree 1073 of 2015, which establishes the requirements, obligations and penalties applicable to supply agents in the distribution, refining, import, storage, wholesale, transportation, retail sale and consumption of liquid fuels.

 

Decree 1073 of 2015 establishes the minimum technical requirements for the construction of storage plants and service stations. This Decree also regulates the distribution of liquid fuels, except LPG establishing the minimum requirements for distributors and the activities and types of agreements permitted for these agents. The Ministry of Mines and Energy also regulates the types of liquid fuels that can be sold and purchased and the penalties for noncompliance with governmental regulations.

 

Pursuant to Law 1430 of 2010, the distribution of fuels in areas near Colombian borders is the responsibility of the Ministry of Mines and Energy and is subject to specific regulations that impose strong control procedures and requirements. The Ministry of Mines and Energy establishes the safety standards for LPG, storage equipment, maintenance and distribution of LPG.

 

The Superintendence of Public Domestic Utilities also oversees the liquefied petroleum gas transportation business. Cenit reports key operational and financial indicators to the Superintendence of Public Domestic Utilities on a monthly basis.

 

3.8.3.2        Regulation Concerning Production and Prices

 

According to the Decree - Law 4130 of 2011 and Decree 1260 of 2013, CREG is in charge of setting the prices of petroleum by-products throughout the entire chain of production and distribution except for current gasoline engine, diesel and biofuels. On the other hand, by Decree 381 of 2012, as amended by Decree 1617 of 2013, the Ministry of Mines and Energy is in charge of setting the methodology to determine the reference price of gasoline, diesel (ACPM), biofuels and mixtures thereof.

 

Then, since May 2012, CREG fixes the prices for most crude oil by-products, but for gasoline, diesel, ACPM and biofuels. CREG determines the methodology to calculate their price while the Ministry of Mines and Energy fixes the relevant prices in accordance with said methodology. The ANH does not intervene in the definition of prices of gasoline and diesel fuel. In addition, under Resolution 007 of 2017, CREG determined the basis for the methodology of compensation of terrestrial transportation of liquid fuel-oil, including current gasoline, diesel and biofuels between the storage plant and the fuel service station.

 

  48  

 

 

The methodology for calculating jet fuel prices is set out in Law 1450 of 2011, and jet fuel prices themselves are set by the Ministry of Mines and Energy.

 

The ANH determines the formula that is used to calculate royalty payments corresponding to the production of crude oil and the crude oil price reference for local refining.

 

Decree 381 of 2012 and 1617 of 2013, as amended by Decree 2881 of 2013, as compiled in Decree 1073 of 2015, restructured the Ministry of Mines and Energy and gave it the responsibility to study industry problems and implement short- and long-term refining planning policies. The Ministry is also responsible for establishing the governmental policies and goals to ensure the reliability, stability and continuity for the production of liquid fuels, biofuels and others.

 

Pursuant to Article 58 of the Petroleum Code, any refining company operating in Colombia must provide a portion or, if needed, the total of its production to supply local demand prior to exporting any production. If local demand increases, and imported crudes are needed, the refining company may charge the State additional transportation costs in proportion to the imported crudes delivered to the refinery.

 

Fuel Price Stabilization Fund (FEPC)

 

The Fuel Price Stabilization Fund was created by Law 1151 of 2007. It is a fund assigned and administered by the Ministry of Finance and Public Credit. Its function is to attenuate, in the domestic market, the impact of fluctuations in fuel prices in international markets.

 

According to article 2.3.4.1.3 of Decree 1068 of 2015, the resources for the functioning of the FEPC come from the following sources: (a) financial returns of resources of the Fund; (b) extraordinary credit resources received from the National Treasury, and (c) funds allocated to the FEPC in the national general budget.

 

The operation of the FEPC is governed by Decree 1068 of 2015 on Chapter 1, and Title 6 (compilation decree regarding treasury public sector). First, refiners and/or importers of regular gasoline and diesel must report to the Ministry of Mines and Energy, the volume of regular gasoline and diesel sold in the previous month, such report to be made within the first 25 days of each month. The report must also contain information corresponding to each fuel disaggregated daily; the discrimination of the volumes sold, and the origin national or imported of the gasoline and diesel sold. If the regular gasoline or the diesel is of national origin, the refiner/importer must inform the refinery from which they come. Secondly, the Ministry of Mines and Energy calculates and liquidates by resolution, the Net Position of each refiner/importer and each fuel to be stabilized by the FEPC.

 

Decree 1068 of 2015 provides that the FEPC will pay in Colombian pesos the value corresponding to the calculation and settlement of the Net Position of each refiner and/or importer within the term defined by the Ministry of Mines and Energy and based on availability of FEPC resources.

 

Law 1819 of 2016 created a tax, related contribution to finance the FEPC. This contribution is caused when the sum of the Differentials of Participation (difference between the Producer Income and the International Parity Price, when the first is greater than the second on the date of issuance of the sales invoice, multiplied by the volume of fuel sold) is greater than the sum of the Differentials of Compensation (the difference presented between the Producer Income and the International Parity Price, when the second is greater than the first on the date of issuance of the sales invoice, multiplied by the volume of fuel sold).

 

The event that generates the contribution is the sale in Colombia of gasoline or ACPM (diesel) by the refiners and/or importers to the wholesale distributor of fuels, according to the price set by the Ministry of Mines and Energy, however, if the importer is at the same time a wholesale distributor, the triggering event shall be the withdraw of the product to be sold. The taxpayer responsible for the contribution is the refiner and/or importer and the active subject is the Nation. The tax base corresponds to the positive difference between the sum of the Differentials of Participation and the sum of the Differentials of Compensation.

 

  49  

 

 

The Ministry of Mines and Energy calculates the contribution through the liquidation of the Net Position of each refiner or importer with respect to the FEPC based on the report that the refiners and/or importers submit. If the sum of the Differentials of Participation is greater than the sum of the Differentials of Compensation and the contribution is caused, the Ministry of Mines and Energy will order the refiner or the importer to pay the contribution to the National Treasury within the 30 days following the execution of the liquidation resolution.

 

Subsequently, Law 1837 of 2017 (article 16) provided that the remaining resources that were in the Ecopetrol’s accounts as of December 2014, as a result of the collection of the Differential Contribution from the FEPC, would be transferred to the General Direction of Public Credit and Treasury of the Ministry of Finance and Public Credit (DGCPTN).

 

Based on the aforementioned law and Decree 1068 of 2015, the Ministry of Mines and Energy settled, through Resolution 31762 of 2017, the value of the remaining resources resulting from the collection of the Differential Contribution of Participation, corresponding to the third quarter of 2013 and the second half of 2014 (from July 1 to December 22, 2014), valued at COP $6,849,420,921 and COP $202,004,538,015 respectively. In this Resolution, it ordered Ecopetrol to transfer the sum of COP $208,853,958,936 to DGCPTN, which has already been transferred by Ecopetrol.

 

In 2017 the Ministry of Mines and Energy issued Resolution 31885 that contains the liquidated net positions corresponding to the period between July 1 and December 28, 2016, and as a result, the FEPC must pay Ecopetrol COP $558,564,915,500.00, which it already paid to Ecopetrol.

 

As of the date of this report, the Ministry of Mines and Energy has not calculated the Net Positions corresponding to the year 2017.

 

3.8.3.3        Regulation of Biofuel and Related Activities

 

The sale and distribution of biofuels is regulated by the Ministry of Mines and Energy. Regulations establish the quality and pricing standards for biofuels and impose minimum requirements for mixing ethanol with gasoline and biodiesel with diesel.

 

The sale and distribution of biofuels is provided under CREG Resolution 240 of 2016, which particularly regulates: a) sorts of market that will be served with biogas and biomethane; b) quality and safety conditions; and c) tariff regime. Pursuant to article 4 of the foregoing Resolution, biogas supply through isolated networks to serve non-regulated users and natural gas vehicles (“GNV” as per its Spanish acronym), shall be incorporated as a public utility company. Furthermore, article 5 provides that biomethane supply through isolated networks or interconnected networks to the National Transportation System shall also be incorporated as a public utility company. Finally, article 12 states that biogas suppliers may develop the production, transportation, distribution and commercialization activities through integrated structures, provided that they keep separate accounts for each activity and grant free access to the networks to both regulated and non-regulated users. To the same extent, production, distribution and commercialization of biomethane through interconnected networks to the National Transportation System may be developed through integrated structures as long as the supplier keeps separate accounts for each activity and grants free access to the networks to both regulated and non-regulated users.

 

3.8.4        Regulation of the Natural Gas Market

 

Decree 1073 of 2015, Part 2, Title 2, Chapter 2, established that all producers have to issue a production statement that includes the volumes of natural gas available for sale for a period of ten years.  This decree established the regime for the selling and marketing of natural gas in Colombia, including specific procedures that regulate the Colombian market in order to manage the remaining natural gas reserves owned by the Nation, and to protect domestic consumers, especially residential consumers, by prioritizing delivery of gas to residential consumers, regulating the export of natural gas and setting forth the export restrictions applicable during an internal shortage of natural gas.

 

Currently in Colombia, other than with respect to the Opón field, the price of natural gas is determined by the market.

 

  50  

 

 

CREG issued Resolution 114 of 2017 which adjusted commercial aspects of the wholesale natural gas market in Colombia and compiled CREG Resolution 089 of 2013 and its modifications. However, pursuant to Decree 1073 of 2015, such procedures do not apply to the following activities: a) natural gas exports; b) natural gas as raw material in petrochemical production; c) natural gas commercialization from minor fields (production capacity under 30 million SCFD); d) natural gas commercialization from hydrocarbon fields under testing phase or which have not yet been declared commercially viable; e) natural gas commercialization from unconventional reservoirs; and f) internal consumption from natural gas producers.

 

CREG determines which agents can participate in the primary and secondary markets.  Ecopetrol is authorized to participate as a seller in the primary market as a natural gas producer and as a buyer in the secondary market when Ecopetrol requires natural gas from other producers for its own needs.  CREG regulations provide that a natural gas producer cannot participate as a merchant of natural gas in the secondary market except that it may purchase gas to meet its existing contractual obligations.  Ecopetrol is also able to re-sell available natural gas transportation capacity into the secondary market.

 

Priority for the Supply of Natural Gas

 

The export of natural gas, in contrast, is not considered a public utility activity under Colombian law and therefore is not subject to Law 142 of 1994.  Nevertheless, the internal supply of natural gas is a priority for the Colombian government and is considered to be a public utility complementary activity, and therefore public utility regulations apply to the internal supply of natural gas.

 

Decree 1073 of 2015 (amended by Decree 2345 of 2015) provides that in the event the supply of natural gas is reduced or halted as a result of a shortage, the Colombian government has the right to suspend the supply of natural gas for export. If such export contracts are suspended by the Colombian government, the export agents are entitled to receive compensation in accordance to article 2.2.2.2.15 and 2.2.2.2.38 of Decree 1073, 2015.  Notwithstanding the foregoing, Decree 1073 of 2015 establishes freedom to export natural gas under normal gas-reserve conditions.  Producers of natural gas may enter into natural gas export contracts if the ratio of proved reserves to consumption exceeds seven years, as determined by the Colombian Energy Planning Authority (or UPME for its Colombian acronym).

 

Decree 1073 of 2015 (amended by Decree 2345 of 2015) establishes an order of supply when restrictions are placed on the supply of natural gas or serious emergency situations arise that preclude the continued provision of certain services, as follows: (i) essential demand, as established in Decree 1073 of 2015, (ii) non-essential demand under an existing agreement with a warranty of uninterrupted provision, and (iii) fair exports delivery.

 

The order of priority for the supply of natural gas is as follows: (i) the operation of the compressor stations of the National Transportation System, (ii) residential users and small business users engaged in the distribution network, (iii) vehicular compressed natural gas and (iv) gas refineries, excluding those destined for self-generation of electricity that can be replaced with energy from National Transportation System, which has first priority.  The Ministry of Mines and Energy also establishes distribution priorities in the event of a natural gas shortfall derived from supply or infrastructure issues.  This order of priority is based on the type of contract, with firm supply contracts having priority over interruptible supply contracts.

 

Decree 1073 of 2015 and CREG Resolution 114 of 2017: i) provide specific procedures and forms of supply agreements determined by CREG pursuant to which an agent may sell and buy natural gas in the Colombian primary and secondary market produced from large fields (capacity of more than 30 million CFPD) and; ii) permit the sale of natural gas from small fields (capacity under 30 million CFPD) pursuant to contracts that fulfill certain regulatory requirements but whose form is not prescribed by law.

3.9        Sustainability Initiatives

 

3.9.1        HSE

 

This section describes the health, safety and environmental (HSE) practices of Ecopetrol S.A. Currently, subsidiaries of Ecopetrol S.A. establish their own HSE models, provided that these models must be consistent with guidelines established by Ecopetrol S.A.

 

3.9.1.1        Ecopetrol S.A.

 

One of the principles that guides Ecopetrol is our commitment to our employees and the development of those communities in which we operate. For that reason, Ecopetrol S.A. is devoted to improving our health, safety and environmental (HSE) practices.

 

We have several programs in place aimed at increasing the safety of our industrial processes and minimizing the number of occupational accidents and other major incidents. Our HSE management model is based on key focus areas that are aligned with our integrated management system.

 

 

 

The results of the HSE strategies in 2017, compared with the prior year, were:

 

(i) A 20% decrease in road accidents, due to improvements in real-time monitoring of drivers’ safety habits, an increase in control check points for tracking tankers and awareness campaigns for drivers.

 

(ii) A 40% decrease in the number of incidents involving employee or contractor injuries that require medical treatment, restricted work or disability.

 

(iii) A reduction in the severity of occupational incidents.

 

(iv) A reduction in oil spills.

 

(v) Improvement in reporting of minor oil spills and identification of their causes.

 

Contingency Plans and Environmental Remediation

 

All of our operational areas have preparedness and emergency response plans, each in accordance with Colombian legal requirements and our new internal guidelines for emergency management.

 

Our preparedness and emergency response plans have been developed based on our analysis of risk scenarios, the estimated consequences of these events and the implementation of strategies to be followed in response to each scenario. These contingency plans have the approval of the ANLA.

 

The objectives of our contingency plans are to:

 

(i) Protect the health and safety of our workers, contractors and the communities in which we operate.

 

(ii) Prevent oil spills and leaks of harmful substances in offshore and onshore areas, fires and explosions and mitigating environmental impacts.

 

  52  

 

 

Our contingency plan includes, among others:

 

(i) Procedures for the containment of oil and other harmful substances, as well as procedures to safeguard the safety of affected communities, the environment and the personnel involved in such containment actions.

 

(ii) Strategies for responding to emergencies located outside of our facilities and mutual aid emergency plans, including actions developed with local environmental authorities, the local community and other organizations for containment and recovery of spilled product, and cleaning and recovery of affected areas, monitoring of the environmental effects and, if the spill or leak has an operational source, compensation for local communities and other affected persons.

 

Further, we are upgrading the skills of our fire brigade, ensuring the reliability of firefighting and emergency equipment and working on improving our performance during drills.

 

In offshore operations, our operator has the responsibility of designing and implementing plans and strategies aligned with international best practices that cover various emergency response scenarios.

 

Total Recordable Incident Rate – Employees and Contractors

 

Ecopetrol S.A. places an important emphasis on understanding, monitoring and controlling our impacts on workers and contractors.

 

Ecopetrol S.A. monitors a standard measure of occupational safety known as the Total Recordable Incidents Frequency Index (TRIF), which represents the number of employee or contractor injuries that require medical treatment or time off for every million hours worked.

 

TRIF has improved from 2.96 incidents per million hours worked in 2012 to 0.64 in 2017. In 2017, 60 recordable cases occurred, where 37% led to restricted work, 18% required medical treatment, and 45% led to disability. Additionally, we had a 40% reduction in occupational incidents compared to 2016 as a result of the sustained implementation of the HSE management system.

Frequency of process safety incidents

 

Our “Process Safety Management” (PSM) strategy is to: first, define high-risk processes; second, prioritize intervention in high-risk processes; and third, apply all PSM elements in the prioritized high-risk processes.

 

Loss of primary containment is the number of unplanned or uncontrolled releases of oil, gas or other hazardous materials.

 

We report Tier 1 process safety events per million hours worked, which are the losses of primary containment of greatest consequence causing harm to a member of the workforce, costly damage to equipment or exceeding defined quantities according to API-754.  We reduced our Tier 1 process safety indicator by 17% compared to 2016 (2017: 0.05 and 2016: 0.06).  The reporting thresholds for API-754 Tier 1 is an unplanned or uncontrolled release of any material, including non-toxic and non-flammable materials, from a process that results in one or more health, safety or environmental consequences set forth under those guidelines. In 2017, there were 0.05 Tier 1 process safety incidents per million hours worked.

Environmental Incidents

 

In 2017, Ecopetrol S.A. recorded 14 environmental incidents compared with 8 in 2016 and 11 in 2015. The volume of oil spills was 50.7 barrels in 2017, a decrease from 202 barrels in 2016 and 207 barrels in 2015. The increase in the numbers of environmental incidents and decrease in oil spills was the result of improvement in the identification of critical equipment operating in high or very high risk conditions, and the implementation of asset integrity plans designed to mitigate those risk conditions.

 

  54  

 

 

Lisama 158/La Fortuna Incident

 

On March 2, 2018, a seepage of water and traces of crude oil occurred near the Lisama 158 well, located in the village of La Fortuna, in the Middle Magdalena Valley of Colombia.  Ecopetrol activated its contingency plan to contain the spill. It is estimated that between March 12 and 15, 550 barrels of crude, mixed with mud and rainwater, seeped into the streams of La Lizama and Caño Muerto.  As of March 30, 2018, the Lisama 158 well was sealed and stopped flowing.  Ecopetrol has ordered an investigation to determine the cause of the incident.   As of the date of this annual report, the National Environmental Licenses Agency (ANLA) has opened an investigation into the incident and the Prosecutor’s Office and other control entities may also open investigations. As of the date of this annual report, Ecopetrol has received third party claims in the form of seven constitutional actions for the protection of fundamental rights. Ecopetrol is not aware of any other third party claims in connection with this incident, and it cannot offer any assurance as to whether or not there will be third party actions in the future.

 

3.9.1.2        Cenit

 

While Cenit had previously followed Ecopetrol’s HSE guidelines, Cenit established its own HSE practice and set and defined its own HSE Key Performance Indicators (KPIs) and targets in respect of its non-operative facilities and offices. This resulted in significant cost reductions with no change in risk levels in 2015, 2016 and 2017. Local and field operations, however, are still conducted under Ecopetrol’s HSE model and guidelines.

 

Cenit established its own HSE Management System based on Decree 1072 of 2015 in 2017 and this will be implemented during 2018. Cenit is also leading the definition of HSE KPIs with all of the midstream subsidiaries to be able to measure the transportation business as a whole and share the lessons learned and best practices within the industry. Cenit consolidated the 2017 KPIs and agreed upon the goals for 2018 for the transportation business to obtain the results for each subsidiary and for the entire group.

 

3.9.1.3        Refinería de Cartagena

 

In 2017, around 7,495,531 man-hours were employed conducting Reficar’s business activities. Our HSE performance indicators for Total Recordable Cases (TRIF), Process Safety Incident (ISP) and Environmental Incident (EI) were well-within our established guidelines.

 

The following table covers Reficar´s Total Recordable Cases (TRIF) for 2015, 2016 and 2017, which includes Ecopetrol Operation and Maintenance (O&M), Reficar and subcontractors. The table presents statistics related to construction, pre-commissioning, start-up and operating activities. Reficar has not reported fatalities (accidents that caused deaths) during the period 2010-2017.

3.9.2        Human Rights

 

Ecopetrol´s Secretary General, through its Corporate Responsibility unit, carries out an annual survey that evaluates stakeholder perception taking into account general and specific criteria relevant to corporate responsibility. For 2017, Ecopetrol decided to include a new section within the survey to measure stakeholder perception in human rights. This section includes criteria such as: (i) freedom of association, (ii) equality and non-discrimination, (iii) communicating how actual and potential human rights impacts are addressed, (iv) supply chain and human rights, (v) grievance mechanism or accountability mechanism, and (vi) human rights education and training. The information gathered through this process will be used by Ecopetrol to design an updated annual Human Rights Plan.

 

3.9.3        Environmental Sustainability

 

3.9.3.1        Environmental Practices

 

Ecopetrol S.A.

 

During 2017, the environmental management strategy of Ecopetrol included the following components:

 

(i) Environmental Viability : this strategy concentrates on obtaining environmental licenses and permits as well as adequate land management that ensures the sustainability of operations through timely prevention efforts and management of environmental impacts, constant and systematic relationships with stakeholders and participation in the sustainable development of the territories in which we operate.

 

(ii) Climate Change : this strategy aims to decrease our carbon emissions and reduce the vulnerability of our operations and our facilities to the effects of climate change through the implementation of four strategic action lines:

 

a. Mitigation : reducing our carbon dioxide emissions and creating carbon offset alternatives;

 

b. Vulnerability and Adaptation : reducing the risks and impacts to our operations posed by climate variability and change;

 

c. Research and Technology : reducing our greenhouse gas emissions through action on research and development, process optimization, implementation of energy efficient strategies, carbon capture and sequestration and diversification into low carbon energy sources; and

 

d. Involvement in Policymaking : informing and influencing government policies on climate change.

 

(iii) Sustainable productive projects and biodiversity : this strategy has as its main objective the adequate management of biodiversity and ecosystem services, aiming to work for the welfare of communities. It has four major areas of work: (i) multifunctional landscape management, (ii) biodiversity conservation, (iii) non-oil income generation and (iv) transfer of technical capabilities for developing sustainable projects.

 

(iv) Eco-efficiency : this strategy aims to maximize our efficient use of resources and mitigate our environmental impacts. Through this strategy, which extends to our supply chain, we seek to utilize energy, materials, and in general all natural resources as efficiently as we can, thereby reducing the environmental impacts from our operations and projects and minimizing emissions, effluents and waste disposal from our operations and projects while taking into account our production benchmarks.

 

  56  

 

 

(v) Integrated Management of Water Resources : this strategy aims to ensure compliance with water resources laws and reduce conflicts over water use in the areas near our projects and operations. Our core focus areas under this strategy are aligned with the objectives defined by the 2010 National Water Policy for the Management of Water Resources in Colombia which focuses on water supply, demand, quality, risk governance and institutional strengthening.

 

In 2017, Ecopetrol reported its performance related to environmental management in its Sustainability Management Report to relevant institutions focused in promoting sustainable issues, such as the environmental benchmarking of ARPEL.

 

3.9.4        Energy Initiatives

 

Refining

 

Ecopetrol’s refining companies have been undertaking significant efforts to make efficient and rational use of energy resources in its production processes and reduce energy consumption and costs and carbon dioxide emissions. We focus on efficiency, reliability and optimization, and energy diversification. During 2017, the Barrancabermeja Refinery’s average monthly energy consumption was 61,782 MWhm (megawatts per hour per month) equivalents, provided through self-generation. Reficar’s average monthly energy consumption was 67,451 MWhm (megawatts per hour per month) equivalents, 99.94% was provided through self-generation and the remaining 0.06% with non-regulated energy purchased from the National Transmission System.

 

Production

 

Further, during 2017, Ecopetrol S.A.’s production sector had an average monthly energy consumption of 381 GWhm (gigawatts per hour per month) for its direct operation, from which 70.8% was provided through self-generation and the remaining 29.2% with non-regulated energy purchased from the National Transmission System.

 

3.10        Related Party and Intercompany Transactions

 

Set forth below is a description of material related party transactions. For additional information about transactions with related parties, see Note 31 to our consolidated financial statements.

 

Ocensa

 

Ecopetrol S.A. has entered into a number of agreements with its 72.65%-owned subsidiary Ocensa, of which the following are the most significant:

 

· In March 1995, Ecopetrol S.A. entered into an agreement for the transportation of crude oil through the Ocensa pipeline. Pursuant to the terms of this agreement, Ecopetrol S.A. was required to make monthly payments that varied depending on both the volume of crude oil transported through the pipeline and a tariff imposed by Ocensa on the basis of Ocensa’s financial projections and their expected volumes of crude oil. On January 17, 2013, this agreement was amended as a result of Ocensa’s new business model. Among other changes, this amendment to the transportation agreement establishes the payment of the tariff calculated according to Resolutions issued in 2010 by the Ministry of Mines and Energy. In 2013, another amendment was executed that modified the terms by which the payments of invoices should be made. In 2015 Ecopetrol received a temporary release of capacity from Vitol of 24,000 barrels per day for segment I and II and 14,000 barrels per day for segment III. In 2017, payments made by Ecopetrol S.A. under this agreement amounted to US$968.2 million.

 

  57  

 

 

· On July 10, 2012, Ecopetrol entered into a ship or pay agreement for the unloading of up to 8 thousand barrels per day of crude oil barrels at Ocensa’s unloading facilities. This agreement was later amended on March 12, 2013 and on July 19, 2013. The fees correspond to a cost of US$1.50 per barrel of crude oil that is unloaded. The agreement has a term of five years. On April 11, 2014 Ecopetrol entered into an additional ship or pay agreement for the operation of Ocensa’s unloading facilities by means of which Ecopetrol has the right to unload an additional volume of up to 2,000 barrels per day. The additional agreement has a five year term. On 2015, as a result of certain modifications made by Ocensa to the unloading facilities that make it possible to receive crude with lower API gravity, the parties signed an addendum to the agreement whereby crude of 18 API can be unloaded by Ecopetrol at Ocensa’s facilities. On March 2016 Ocensa temporarily modified the fee for unloading operations based on the stretch market conditions to US$0.50. By virtue of these agreements, Ecopetrol S.A. paid fees of US$2.39 million to Ocensa in 2017.

 

· On October 28, 2013, Ecopetrol entered into a natural gas supply contract in force until November 30, 2018, pursuant to which Ecopetrol S.A. supplies gas to Ocensa and receives a fixed price per MBTU (million British Thermal Units). This agreement replaced the contract for natural gas supply in Cusiana entered into on December of 2004, under which Ocensa paid a variable rate to Ecopetrol. In 2017, Ecopetrol S.A. received an aggregate sum of US$5.12 million under the contract.

 

Ocensa has entered into the following agreements, among others, with some of our other subsidiaries:

 

· In March 1995, Equion and Santiago Oil Company entered into agreements for the transportation of crude oil through the Oleoducto Central S.A. (Ocensa) pipeline. In November 2012, Equion and Santiago Oil Company transferred, by means of various transactions, its shares (24.8%) and transportation rights (19.8%) holdings in the Ocensa pipeline to wholly owned subsidiaries of Ecopetrol S.A. (51%) and Talisman (49%). Equion and Santiago Oil Company kept 5% of transportation rights in Ocensa. In 2014, the transportation fees billed by Ocensa were: Equion (US$44.4 million), Santiago Oil Company (US$3.8 million) and Hocol (US$30.8 million). On January 17, 2013, this agreement was amended as a result of Ocensa’s new business model. Among other changes, the amendment to the transportation agreement establishes that tariff payments are to be calculated according to resolutions issued by the Ministry of Mines and Energy. On May 23, 2013, another amendment was executed that modified the terms by which the payments of invoices should be made. In 2017, Equion paid Ocensa US$5.2 million and Santiago Oil Company US$0.774 million, in each case for transportation fees. Hocol paid Ocensa, as assignee of transportation rights from original shippers, US$0.012 million in 2017.

 

· On July 9, 2012, Ocensa and ODL entered into a strategic alliance for the dilution of crude oil in the Cusiana station. The term of this contract is of five years. Once the initial term of the agreement ends, Ocensa has a purchase option over the assets that perform the dilution process. In 2015, the parties signed two addenda to the agreement in order to include additional construction work to be conducted by ODL and supervised by Ocensa for an agreed fee. ODL paid Ocensa US$2.3 million under this contract in 2017.

 

Oleoducto de Colombia S.A. (ODC)

 

Ecopetrol S.A. entered into the following agreements with its 73%-owned subsidiary ODC:

 

· In July 1992, a take-and-pay agreement was signed for the transportation of hydrocarbons. Pursuant to this agreement, Ecopetrol S.A. must pay a previously agreed tariff for the volume of hydrocarbons transported. The duration of this agreement is indefinite; however the contract will remain in force as long as Ecopetrol S.A. holds shares in Oleoducto de Colombia S.A., whether directly, or through an affiliate. As of January 2013, the parties agreed that the applicable tariff would be the one set by the Ministry of Mines and Energy (the “MME Tariff”). The MME Tariff had been set in 2011 for a four-year term, with a yearly adjustment based on the consumer price index. In 2017, payments made by Ecopetrol S.A. under this agreement amounted to US$83.7 million.

This tariff is collected through a trust; the trust is also responsible for making the debt service payments to the banks. The duration of the ship-or-pay agreement is the earlier of 12 years or when the credit has been entirely paid, and the duration of the ship-and-pay agreement is 20 years after the ship-or-pay terminates. Under these agreements, Oleoducto Bicentenario has committed to transport at least 110,000 bpd, of which the 55% of the agreement volume is provided directly by Ecopetrol S.A. and 0.97% indirectly by Hocol. In March 2014, the parties signed an amendment to these agreements under which Oleoducto Bicentenario acknowledges having received an advance tariff payment which can be amortized through volumes of crude transported in excess of 110,000 bpd. In April 2015, these agreements were amended to modify certain definitions to reflect new terms from the negotiation of the debt, which included a modification of participant banks and a reduction of the interest rate.

Ecopetrol S.A. relations with unions are based on a permanent dialogue and communication sessions where different matters are discussed in order to solve and prevent any labor conflict.

 

Our current collective bargaining agreement has been in effect since 2014 and has a term of four years, expiring on June 30, 2018. In 2016, the agreement was reviewed on application matters, except for monetary expenses (including wages and benefits). This review ended with a mutual arrangement document, signed on December 10, 2016.

 

There will be no changes to these terms until June 2018 or till the end of the eventual negotiation process. This agreement currently covers all workers benefiting from the Collective Labor Convention, regardless of whether they are part of any labor union.

 

4. Financial Review

 

Our consolidated financial statements for the years ended December 31, 2015, 2016 and 2017 were prepared in accordance with IFRS.

 

  66  

 

 

IFRS differs in certain significant aspects from the current Colombian IFRS (which is the accounting standard we use for local statutory reporting purposes). As a result, our financial information presented under IFRS is not directly comparable to certain of our financial information presented under Colombian IFRS. A description of the differences between Colombian IFRS and IFRS is presented under Summary of Differences between Internal Reporting (Colombian IFRS and IFRS) below.

 

Our consolidated financial statements were consolidated line by line and all transactions and significant balances between affiliates have been eliminated. These financial statements include the financial results of all subsidiaries companies controlled, directly or indirectly, by Ecopetrol S.A. See Exhibit 1—Consolidated companies, associates and joint ventures, to our consolidated financial statements included in this annual report.

 

4.1        Factors Affecting Our Operating Results

 

Our operating results were affected mainly by international prices of crude oil and, to a somewhat lesser extent, international prices for refined products and local prices for natural gas, as well as sales volumes, product mix, exchange rate and our operational performance. Crude oil prices and volumes are particularly important to the results of our exploration and production segment. This is because as export volumes or export prices of crude oil and products decrease or increase, our revenues do also. Results from our refining activities are also affected by the price of crude oil used as raw material, changes in product prices in the international market, change in environmental regulations, conversion ratios and utilization rates and refining capacity, all of which affect our refining margins. Changes in the value of foreign currencies, particularly the U.S. dollar against the Colombian Peso, can also have a significant effect on our financial statements. Finally, terrorist attacks by guerillas against our pipelines and other facilities or social unrest can lead to loss of revenues by restricting the availability of transport systems for exports or sales of crude oil and products and/or production activities, in addition to the direct costs of repairing and cleaning.

 

Sales volumes and prices

 

Our results from the exploration and production segment depend mainly on our sales volumes and average local and international prices for crude oil, petrochemicals and natural gas. Additionally, sales volumes also reflect the purchase of crude oil and natural gas that we make from third parties and the ANH.

 

We sell crude oil and natural gas in the local and the international market. We also process crude oil at the Barrancabermeja and Cartagena refineries and sell refined and other petrochemical products in the local and international markets.

 

Local sales and prices

 

We have a number of crude oil short-term commercial agreements with local customers, and natural gas short and long-term supply contracts with gas-fired power plants and local natural gas distribution companies. Local sale prices are determined in accordance with existing regulations, contractual arrangements and the spot market linked to international benchmarks. Local sales represent 50.4% of our total revenues, on average, for the past three years.

 

International Sales and Prices

 

Our foreign sales represented 49.6% of our total revenues, on average, for the past three years.

 

International sale prices are determined in accordance with contractual arrangements and the spot market linked to international benchmarks primarily ICE Brent benchmark.

 

A market diversification strategy has allowed us to capture markets where we have been able to obtain higher prices for our crudes and refined products. We sell our crudes and refined products in various regions, such as the U.S., Central America and the Caribbean, Asia and Europe. In our negotiations with potential customers, we seek to use the most liquid benchmark reference prices in each region.

 

  67  

 

 

Exploration costs

 

We account for exploratory drilling costs using the successful efforts method, whereby all costs associated with the exploration and drilling of productive wells are initially capitalized. Costs incurred in exploring and drilling dry or unsuccessful wells are expensed in the period in which the well is determined to be a dry or unsuccessful well and are accounted for under “Exploration and Project expenses.” Consequently, an increase in the number of exploratory wells we declare as dry or unsuccessful will negatively affect our results and may cause volatility in our operating expenses.

 

Royalties

 

Each of our production contracts has its own royalty arrangement in accordance with applicable law. Law 141 of 1994 established a royalty fixed rate equivalent to 20% of total production. In 1999, a modification to the royalty system established a sliding scale for royalty percentage linked to the production level of crude oil and natural gas to fields discovered after July 29, 1999, depending on whether the production is crude oil or natural gas, and on the quality of the crude oil produced. Since 2002, as a result of the enactment of Law 756 of 2002, the royalty percentage has ranged from 8% for fields producing up to five thousand bpd to 25% for fields producing an excess of 600 thousand bpd. Producing fields pay royalties in accordance with the applicable royalty rate at the time of the discovery. Also, Law 756 of 2002 establishes that in the fields of the association contracts that finalize or revert back, an additional royalty rate of 12% of the basic production applies.

 

Since January 2014, the ANH has collected natural gas production royalties from producers settled in cash based on a formula, regardless of whether a producer has sold the gas. As a result, we no longer commercialize this gas on behalf of the ANH. In addition, because the royalties are now payable to the ANH in cash, all the gas we produce is considered part of our reserves and production, without any deduction for royalties. The cost of natural gas royalties totaled COP$449,959 million in 2017.

 

Purchases of hydrocarbons

 

We purchase all crude oil delivered to the ANH as royalties by us and by third parties. The purchase price is calculated according to a formula set forth in a contract between Ecopetrol and the ANH that reflects our export sales prices (crudes and products), a quality adjustment for API gravity and sulfur content, transportation rates from the wellhead to the Coveñas or Tumaco ports and a marketing fee. We sell the physical product purchased from the ANH as part of our ordinary business. In June 2016, the contract between the ANH and us was extended until June 30, 2018.

 

Since 2016, we have imported crude oil for Reficar feedstock when such imports result in better operational or economic performance of the Ecopetrol Group.

 

4.2        Effect of Taxes, Exchange Rate Variation, Inflation and the Price of Oil on our Results

 

4.2.1        Taxes

 

In December 2016, the Colombian Congress adopted Law 1819, which introduced changes to the Colombian tax system as follows:

 

· The CREE and CREE surtax were eliminated. Instead, a unified income tax rate was set, which will be 33% for 2018 and onwards.

 

· An income tax surtax for profits above COP$800 million of 4% in 2018.

 

· Taxpayers must calculate their taxable income taking as initial base the year and result under Colombian IFRS. Accounting profit is reconciled to obtain the net income tax which is the basis to calculate the income tax.

 

  68  

 

 

· From fiscal year 2017 onwards, a withholding tax on dividends paid is as follows:

 

(i) For non-resident shareholders: (i) a 5% dividend tax on dividends distributed from profits taxed at the corporate level; and (ii) a 35% withholding tax rate on dividends distributed from profits not taxed at the corporate level, plus an additional 5% dividend tax after applying the initial 35% withholding tax rate.

 

(ii) For Colombian individuals: dividends paid are taxed at 5% if they are between 600 and 1,000 Tax Value Unit (UVT – Unidad de Valor Tributario for its acronym in Spanish) and 10% if they are greater than 1,000 UVT .

 

· Dividends paid to local corporations are not subject to any tax, provided that such dividends were taxed at the corporate level.

 

· 2017 and future loss carryforwards are subject to a time-limit of 12 years.

 

· Depreciation and amortization methods and annual percentages are limited to those established in the fiscal framework and depend on the type of asset. For example, machinery and equipment depreciate at an annual rate of 10%, infrastructure (including pipelines) at 2.22% and vehicles and computers at 20%, among others.

 

· The income tax for tax free zone users is 20% for fiscal year 2018. The tax rate of companies located in a free trade zone with legal stability is 15%, which typically applies during the contract’s duration.

 

· The presumptive income rate increased to 3.5% in 2017 from 3% in 2016.

 

· Tax rate for VAT increased to 19% in 2017 from 16% in 2016.

 

· The charge on financial transactions is 0.004%, with half of the tax liability being deductible.

 

· Carbon tax accrues on the carbon content of fossil fuels used for combustion. The rate will be COP$15,000 per ton of CO2.

 

The 2016 Tax Reform included two tax benefits that are expected to improve the operations of the oil and gas industry:

 

“CERT: Certificado de Reembolso Tributario” incentive:

 

· For exploration activities, the “CERT” (for its acronym in Spanish) incentive was approved, consisting of the reimbursement of part of the investment made in the exploration phase.

 

· The CERT will be granted when the income tax return is filed.

 

· The CERT can only be redeemed to pay taxes at the national level and its effective maturity date is two years after it is issued. Nevertheless, Decree 2253 of 2017 establishes that a CERT redemption can be made from year two to year five, as from the date of the granting of the incentive. The CERT can also be sold and traded in fixed income market.

 

· For production activities, the CERT reimbursement will be granted exclusively to investments that increase the recovery factor, i.e. investments that increase the reserves that are currently proved in certain wells.

 

· On December 29, 2017, the Colombian Government issued Decree 2253, which establishes that companies who (i) qualify as operators of association agreements entered into with Ecopetrol, (ii) have exploration and production of hydrocarbons agreements and (iii) are currently involved in the exploration and production of hydrocarbons, among others, can also qualify for the CERT. Additionally, the CERT will not qualify as taxable income or capital gain for the taxpayer receiving or acquiring such incentive.

 

  69  

 

 

· On March 23, 2018, the following Resolutions were issued in order to regulate the procedures and requirements that companies must comply to claim the CERT: 0860 of Ministry of Finance and Public Credit, 108 of ANH and 40284 and 40285 of Ministry of Mines and Energy.

 

Refundable VAT on O&G exploration:

 

· Taxpayers in the oil and gas industry are entitled to refund VAT paid in the exploration phase for offshore projects. Taxpayers can request for this VAT as of the next fiscal year in which the investment was made. VAT that is reimbursed cannot be used as a higher cost or expense for income tax purposes.

 

4.2.2        Exchange Rate Variation

 

The functional currency of each of the companies of Ecopetrol Group is determined in relation to the main economic environment where each company operates; however our consolidated financial results are reported in Colombian Pesos, which is the Ecopetrol Group’s functional and presentation currency. A substantial part of our consolidated revenues coming from Ecopetrol Group companies whose functional currency is the Colombian Peso, the U.S. dollar-Colombian Peso is derived from local sales and exports of crude oil, natural gas and refined products sold at prices referenced to benchmarks quoted in U.S. dollars. Therefore, they are exposed to foreign currency exchange risk on revenues, capital expenditures and financial instruments that are denominated in a currency other than its functional currency.

 

Fluctuations in the U.S. dollar-Colombian Peso exchange rate have effects on our consolidated financial statements. As crude oil is priced in U.S. dollars, fluctuations in the exchange rate of the Colombian Peso against the U.S. dollar may have a significant impact on revenues, cost, assets and liabilities held in foreign currency.

 

An appreciation of the Colombian Peso has a negative impact on our results of operations because our revenues from exports of crude oil, natural gas and refined products are primarily expressed in U.S. Dollars. Costs of imported goods and contracted services expressed in U.S. dollars will also be lower when expressed in Colombian Pesos, but on balance, our operating income in Colombian Pesos tends to decline when the Colombian Peso appreciates, other factors being equal. The appreciation of the Colombian peso against the U.S. dollar also decreases the debt service requirements of our Companies with the Colombian peso as their functional currency, as the amount of the Colombian pesos necessary to pay principal and interest on foreign currency debt decreases with the appreciation of the Colombian peso.

 

Conversely, when the Colombian Peso depreciates against the U.S. dollar, our reported revenues, costs related to imported goods and services, interest costs, and operating income, all tend to increase.

 

During 2017, the Colombian peso appreciated on average 3.35% against the U.S. dollar. In 2016 and 2015, the Colombian Peso depreciated on average 11.18%, and 37.28%, respectively, against the U.S. dollar. Additionally, as of December 31, 2017 and December 31, 2016 the Colombian Peso/U.S. dollar exchange rate appreciated 0.56% and 4.72%, respectively from the rate a year earlier. As of December 31, 2015, in contrast, the Colombian Peso depreciated 31.64%, from the rate a year earlier.

 

In 2017, our consolidated debt in foreign currency decreased by a total of US$2,582 million mainly as a result of prepayments of foreign currency denominated loans of US$2,400 million and amortization of foreign currency capital expenditures. In 2016, our consolidated debt in foreign currency increased by a total of US$975 million as Ecopetrol S.A. raised US$475 million through international loans and US$500 million through an international bond issuance. In 2015, our consolidated debt in foreign currency increased by a total of US$3,425 million as Ecopetrol S.A. raised US$1,925 million through an international loan and US$1,500 million through an international bond issuance.

 

As of December 31, 2017 our U.S. dollar denominated total debt was US$12,590 million, which we recognize in our financial statements at its amortized cost, which corresponds to the present value of cash flows, discounted at the effective interest rate. Out of this total, US$11,985 million relates to Ecopetrol S.A., whose functional currency is the Colombian Peso. Therefore, when the Colombian Peso depreciates against the U.S. dollar, Ecopetrol S.A. is exposed to an exchange rate loss. In contrast, when the Colombian Peso appreciates against the U.S. dollar, Ecopetrol S.A. has an exchange rate gain. Some of the Ecopetrol Group companies have the U.S. dollar as their functional currency and are not exposed to a material exchange rate risk resulting from fluctuations in the Colombian Peso against the U.S. dollar. On the asset side, when the financial statements of the Group are consolidated, the exchange rate differential of the subsidiaries’ assets and liabilities whose functional currency is the U.S. dollar is recognized directly in equity, as part of Other comprehensive income.

 

  70  

 

 

In 2015, Ecopetrol S.A. adopted hedge accounting, using two types of natural hedges with its U.S. dollar debt as a financial instrument: i) a cash flow hedge for exports of crude oil and ii) a hedge of the net investment in foreign operations. As a result of the implementation of both hedges 71.2% ($8,532 million) of Ecopetrol S.A.’s debt in U.S. dollars, as of December 31, 2017, was designated as a hedge. With the adoption of hedge accounting, the effect of the volatility of the foreign exchange rate on the hedged portion of the debt is recognized directly in equity, as part of Other comprehensive income.

 

The remaining portion of Ecopetrol S.A.’s U.S. dollar-denominated debt, as well as the financial assets and liabilities denominated in foreign currency, continues to be exposed to the fluctuation in the exchange rate, which means that an appreciation of the Colombian peso against the U.S. dollar could generate a loss for companies whose functional currency is the Colombian peso that have a net position in U.S. dollars or a gain if they have a net liability position in U.S. dollars. Conversely, a depreciation of the Colombian peso against the U.S. dollar could generate a gain for companies whose functional currency is the Colombian peso that have a net position in U.S. dollars or a loss if they have a net liability position in U.S. dollars.

 

As of December 31, 2017, Ecopetrol Group companies with the Colombian peso as their functional currency have a net U.S. dollar position close to zero after the implementation of the natural hedging previously mentioned above, neutralizing the effect of exchange rate fluctuations in their results for the year. The companies with the U.S. dollar as their functional currency have a net U.S. dollar position of US$1,699 million and are not exposed to a material exchange rate risk resulting from fluctuations in the Colombian peso against the U.S. dollar, as discussed above.

 

4.2.3        Effects of Inflation

 

The average annual rate of inflation in Colombia for the past ten years is 4.3%. It decreased in 2017 as compared to 2016. As measured by the general consumer price index, average annual inflation in Colombia for the years ended December 31, 2017, 2016 and 2015 was 4.09%, 5.75%, and 6.77%, respectively. The decrease in inflation in 2017 is mainly explained by the recovery of the agricultural sector given the end of the “El Niño” weather phenomenon and the nonoccurrence of agricultural and freight transport stoppages that occurred in 2016. The decrease in inflation is also related to the weakness of consumer demand and the monetary policy applied by the central bank. Cost inflation in the prices of goods, raw materials, interest cost of debt in local currency indexed to inflation and services for operation of oil and gas producing assets can vary over time and between each market segment.

 

4.2.4        Effects of the Price of Oil

 

The average price of ICE Brent crude was US$54.7 per barrel in 2017 as compared to US$45.10 per barrel in 2016 and US$53.60 per barrel in 2015. ( See section Strategy and Market Overview ). In addition, Ecopetrol’s average crude oil basket price relative to ICE Brent reported a discount of US$6.90 in 2017, a lower discount than the US$9.40 and US$9.70 observed in 2016 and 2015, respectively, due to an active commercial strategy, including seeking more valuable markets for our crude oil, and strengthening the demand for our heavy crude oil in the international market. Therefore, our average price crude oil basket was US$47.80 per barrel in 2017 as compared to US$35.70 per barrel in 2016 and US$43.90 per barrel in 2015, which represents an increase of US$12.10 per barrel in 2017 compared to 2016.

 

In the Operating Results section below, we present the impact of the price increase in our revenue and cost of sales.

 

Additionally, fluctuations in the price of oil had an impact on the value of our oil and gas reserves. Reserves valuation is made in accordance with SEC price regulations. Volatility in hydrocarbon prices, refining margins and reserves, as well as changes in environmental regulations may lead to the recognition of impairment or recovery of assets.

 

  71  

 

 

In 2015, the adverse economic context faced by the hydrocarbons sector resulted in a reduction in forecasted oil prices and an increase in market and country risk reflected in the discount rate, as well as a reduction in the recoverable reserves amount and refining margin, among other factors, Ecopetrol recognized an impairment of non-current assets of COP$7,864,875 million before taxes.

 

In 2016, in connection with our evaluation of the recoverable amount of the assets value, which includes the variation in estimations of future prices under the current scenarios of OPEC’s oil quota agreements and the impact resulting from changes on specifications issued by the International Marine Organization agreement regarding marine pollution -Marpol- on crude and fuels with high sulfur content, Ecopetrol recognized an impairment of non-current assets of COP$928,747 million before taxes.

 

In 2017, Ecopetrol had a COP$1,311,138 million net reversal of prior year impairments primarily as a result an improved hydrocarbon prices outlook, incorporation of new reserves. Ecopetrol’s crude an improved oil basket price discount as compared to the ICE Brent crude oil price, favorable refining margins outlook and technical operational capacity, among other factors.

 

For additional information about impairment charges and reversals, see section Operating Results—Consolidated Results of Operations—Impairment of non-current assets and Note 18 to our consolidated financial statements.

 

4.3        Accounting Policies

 

Our consolidated financial statements for the years ended December 31, 2015, 2016 and 2017 were prepared in accordance with IFRS. The detail of the accounting policies is described in Note 4 to our consolidated financial statements.

 

4.4        Critical Accounting Judgments and Estimates

 

Critical accounting policies are those policies that require us to exercise judgment or involve a higher degree of complexity in the application of the accounting policies that currently affect our financial condition and results of operations. The accounting judgments and estimates we make in these contexts require us to calculate variables and make assumptions about matters that are highly uncertain. In each case, if we had made other estimates, or if changes in the estimates occur from period to period, our financial condition and results of operations could be materially affected.

 

See Note 3 to our consolidated financial statements for a summary of the critical accounting judgments and estimates applicable to us. There are many other areas in which we use estimates about uncertain matters, but we believe the reasonably likely effect of changed or different estimates would not be material to our financial presentation.

In 2017, total revenues increased by 15.4% as compared to 2016, primarily as a result of a COP$$10,971,709 million increase in revenues mainly due to the 33.9%, or US$12.1 per barrel increase of our average crude oil basket price and a smaller discount of Ecopetrol’s average crude oil basket price from international prices. This increase was partially offset by: (i) a COP$$1,894,819 million decrease in revenues attributable to the decrease in our sales volume and a COP$261,200 decrease in services provided by our transportations and logistics segment and (ii) the 3.35% appreciation of the Colombian Peso against the U.S. dollar, from an average exchange rate of COP$3,053.42/US$1.00 in 2016 to an average exchange rate of COP$$2,951.15 /US$1.00 in 2017, resulting in a decrease in sales revenue from exports, which represented a decrease of COP$1,347,023 million.

 

The decrease of our sales volume in 2017 as compared to 2016 was the result of (i) the 3.7%, or 6 mbe, decrease in our crude sales volume caused mainly by lower crude exports due to a greater allocation of domestic crudes to supply Reficar in order to replace imports, (ii) the 6.7%, or 10.7 mbe, decrease in refined products volumes due to lower exports of diesel, primarily due to: (a) our commercial strategy of focusing on allocating higher volumes to the domestic market to supply local demand and replace imports which resulted in lower cost of sales and better gross margin, (b) lower exports of fuel oil, and (c) a decrease in production at the Barrancabermeja refinery as a result of reliance on more efficient alternative sources, and (iii) the 3%, or 0.86 mbe, decrease in natural gas sales volume due to continued lower thermal demand as a result of no effect of the “El Niño” weather phenomenon that ended in the middle of 2016.

 

In 2016, total revenues decreased by 7.4% as compared to 2015, primarily as a result of: (i) a COP$6,456,917 million decrease in revenues mainly due to the 18.6%, or US$8.2 per barrel reduction of our average crude oil basket price, (ii) a COP$1,572,854 million decrease in revenues attributable to the decrease in our sales volume and lower services provided by our transportations and logistics segment. This decrease was partially offset by the 11.2% devaluation of the Colombian Peso against the U.S. dollar, from an average exchange rate of COP$2,746.47/US$1.00 in 2015 to an average exchange rate of COP$3,053.42/US$1.00 in 2016, resulting in an increase in sales revenue from exports, which represented an increase of COP$4,168,061 million.

 

The decrease of our sales volume in 2016 as compared to 2015 was the result of (i) the 18.1%, or 36.4 mbe, decrease in our crude sales volume caused mainly by lower crude exports due to production decline, reduced purchases by third parties and lower availability of crude due to its use for feedstock at Reficar, and (ii) the 15.6%, or 5.3 mbe, decrease in natural gas sales volume due to lower thermal demand as a result of the end of the “El Niño” weather phenomenon and the termination of our sales contract to Venezuela on June 30, 2015. This decrease in sales volume was partially offset by the 20.2%, or 26.8 mbe, increase in sales of refined products given the increase of operations at Reficar and higher demand due to the growth in the number of motor vehicles in Colombia.

 

4.5.1.2        Cost of Sales

 

Our cost of sales was principally affected by the factors described below. See Note 26 to our consolidated financial statements for more detail.

 

Cost of sales in 2017 was COP$36,908,325 million, representing a COP$2,656,902 million or 7.8% increase as compared to 2016, primarily as a result of the following factors:

 

· A COP$1,439,366 million increase in the purchase costs of crude oil, natural gas and refined products, which were purchased for sales and, in the case of crude oil, for refining, which was primarily the result of (i) higher average purchase prices due to the COP$4,322,867 million increase in international benchmark prices for crude oil, natural gas and refined products, and (ii) increased crude oil imports required at Reficar for its operations. This increase was partially offset by (i) a COP$2,399,596 decrease in volumes purchased due to lower imports of fuels, especially diesel and gasoline, due to our strategy described above of replacing imports with products produced by Reficar, and lower diluent consumption, due to the strategy of marketing high-viscosity crudes and co-dilution with LPG, and (ii) COP$543,905 million decrease in costs in Colombian Peso terms due to the appreciation of the average exchange rate of the Colombian Peso against the U.S. dollar.

 

  74  

 

 

· A COP$ 748,051 million increase in depreciation, amortization and depletion charges due to (i) higher depreciation as a result of the beginning of operations of the Gunflint field by Ecopetrol America Inc. in August 2016, (ii) a decrease in hydrocarbon proved developed reserves in 2016 as compared to 2015, which in turn led to an increase in depreciation expenses, and (iii) the capitalization of project costs and maintenance in our transportation system.

 

· A COP$415,534 million increase in the cost of processing materials and operating supplies due to an increase in our operational activities.

 

· A COP$243,702 million increase in labor costs, which is primarily the result of: (i) no performance variable bonus payment in 2016, (ii) a 5.2% salary increase in 2017 and (iii) the payment of salaries and health services for employees of the Rubiales field for the entire year of 2017, after Ecopetrol assumed operations in July 2016.

 

· A COP$41,471 million decrease in other minor items.

 

The factors mentioned above were partially offset by a COP$231,222 million increase in inventories and an increase in unit costs associated with the increase of the Brent price of crude oils and products.

 

Cost of sales in 2016 was COP$34,251,423 million, representing a COP$2,743,093 million or 7.4% decrease as compared to 2015, primarily as a result of the following factors:

 

· A COP$2,043,600 million decrease in the purchase costs of crude oil, natural gas and refined products, which were purchased for sales and in the case of raw materials for refining, which was primarily the result of (i) a lower average purchase prices due to the COP$3,571,691 million decrease in international benchmark prices for crude oil, natural gas and refined products, and (ii) a COP$142,758 decrease in volumes purchased due to the positive effect of a decrease in imports by Reficar and lower products imports by the Refinery of Cartagena given its beginning of operation partially offset by greater purchases of crude oil in the international market for its supply. This decrease was partially offset by a COP$1,670,849 million increase in the average exchange rate of the Colombian Peso against the U.S. dollar (which led to increased costs in Colombian Peso terms).

 

· A COP$966,578 million decrease in maintenance and contracted services cost, which was primarily the result of (i) a COP$630,576 million decrease in contracted services, mainly due to cost savings achieved through the implementation of our business transformation plan and the transfer of the direct operation of the Rubiales field to Ecopetrol in July 2016; and (ii) a COP$336,002 million decrease in maintenance costs, mainly due to savings achieved from our 2016 maintenance plan which included the renegotiation of fees and the optimization of time without affecting operations.

 

· A COP$587,696 million decrease in transportation costs, which was the result of an optimization of the use of tanker trucks. This optimization included improvements in the pipeline transportation system for the transportation of heavy crude oil and consequently less use of tanker trucks, use of shorter transportation routes and renegotiation of fees for contracts.

 

The factors mentioned above were partially offset by a (i) COP$784,266 million increase in the amortization, depletion and depreciation of property, plant and equipment in connection with the start-up of the Reficar units and capitalization of major maintenance costs at the Barrancabermeja refinery and (ii) a COP$70,515 million decrease in other minor items.

 

4.5.1.3        Operating Expenses before impairment of non-current assets effects

 

Operating expenses and selling, general and administrative expenses before taking into account the impairment of non-current assets, amounted to COP$4,185,186 million in 2017, a COP$215,657 million or 4.9% decrease as compared to 2016, mainly as a result of the following factors (see Notes 27 and 28 to our consolidated financial statements for more detail).

 

  75  

 

 

· A COP$451,095 million increase in other income due to the acquisition of an additional 11.6% interest at the K2 field in the Gulf of Mexico, which generated a gain due to the increase in the book value of the asset above the price paid for the additional interest. This non-cash gain is the result of the fair value valuation of the interest acquired, reflecting a price increase between the date of the deal and the price outlook by the end of 2017, among other factors.

 

· A COP$263,034 million decrease in taxes mainly due to the reduction of the wealth tax rate from 1% in 2016 to 0.4% in 2017, which was partially offset by an increase in Hocol’s tax expenses as a result of a regulatory trial on deductible expenses.

 

· A COP$122,427 million increase in other income due to the sale of the following fields in 2017: Sogamoso, Río Zulia, Río de Oro and Puerto Barco, Santana, Nancy Maxine Burdine and Valdivia Almagro.

 

This decrease was partially offset by:

 

· A COP$613,350 million increase in exploratory expenses as a result of a higher seismic activity and the recognition of spending on exploratory activity mainly at the Kronos-1, Parmer-1, Warrior 2, Lunera-1, Brama-1, Molusco-1, Godric, Dumbo and Pollera wells,

 

· A COP$7,549 million increase in other minor items.

 

Operating expenses and selling, general and administrative expenses before taking into account the impairment of non-current assets, amounted to COP$4,400,843 million in 2016, a COP$ 955,872 million (17.8%) decrease as compared to 2015, mainly as a result of the following factors (see Notes 27 and 28 to our consolidated financial statements for more detail).

 

· A COP$855,659 million decrease in exploratory expenses as a result of decreased seismic activity and fewer dry wells reported in the period;

 

· A COP$309,746 million decrease in commissions, fees, freights and services due to optimization achieved through the implementation of the transformation program.

 

This decrease was partially offset by:

 

· A COP$134,665 million increase in labor expenses mainly due to the implementation of a voluntary retirement plan. This plan includes benefits such as monthly income, education and health until the date on which the employees are granted their legal retirement pension.

 

· A COP$74,868 million increase in other minor items.

 

Each of our operating segments bears the costs and expenses incurred for product use and marketing and each segment assumes administrative expenses and all non-operational transactions related to its activity. Discussion of operating expenses by business segment is included in the section Financial Review—Operating Results—Consolidated Results of Operations—Segment Performance and Analysis .

 

4.5.1.4        Impairment of non-current assets

 

The impairment of our non-current assets includes expenses (or recovery) of impairment of property, plant and equipment and natural resources, investments in companies, goodwill and other non-current assets. The Company is exposed to future risks derived mainly from variations in: (i) oil prices outlook, (ii) refining margins and profitability, (iii) cost profile, (iv) investment and maintenance expenses, (v) amount of recoverable reserves, (vi) market and country risk assessments reflected in the discount rate, and (vii) changes in domestic and international regulations, among others.

 

  76  

 

 

Any change in the foregoing variables used to calculate the recoverable amount of a non-current asset can have a material effect on the recognition of either losses or recovery of impairment charges in the profit or loss statement. In our business segments highly sensitive variables can include among others: (i) in the exploration and production segment, variations of the hydrocarbon prices outlook; (ii) in the refining segment, changes in product and crude oil prices, discount rate, refining margins, changes in environmental regulations, cost structure and the level of capital expenditures; (iii) in the transportation and logistics segment, changes in tariffs regulation and volumes transported. (See Notes 3.2, 4.12 and 18 to our consolidated financial statements for more detail).

 

In 2017, we had a COP$1,311,138 million net reversal of impairment of non-current assets, as compared to impairment losses of COP$928,747 million in 2016 and COP$7,864,875 million in 2015. These impairments are a non-cash accounting effect and consequently they do not involve any disbursement or income. Further, any cumulative impairment amount of non-current assets is susceptible to reversion when the fair value of the asset exceeds its book value. On the contrary, in the event that the book value exceeds the fair value of the asset, an additional impairment expense could be recognized.

 

The partial reversal of the impairment recorded in previous years is primarily the result of an improved hydrocarbon prices outlook, incorporation of new reserves, Ecopetrol’s crude oil basket price discounts as compared to the ICE Brent crude price, favorable refining margins outlook, market conditions affecting the discount rate and technical operational capacity, among other factors.

 

The impairment losses recognized in 2016 and 2015 were mainly due to lower estimates of the outlook for oil prices given the oil price environment during those years, operational variables in the exploration and production and refining segments, market and country risk assessments reflected in the discount rate, and a reduction in the amount of recoverable reserves, among others.

 

For more information regarding impairment by segment, see the section Financial Review—Operating Results—Consolidated Results of Operations—Segment Performance and Analysis .

 

4.5.1.5        Finance Results, Net

 

Finance results, net, mainly includes exchange rate gains or losses, interest expense, yields and interest from our investments and non-current liabilities financial costs (asset retirement obligation and post-benefits plan).

 

Finance results, net, amounted to a loss of COP$2,495,731 million in 2017 as compared to a loss of COP$1,175,367 million in 2016. This increase in loss was mainly due to:

 

· The negative impact (COP$970,916 million) resulting from the 0.56% appreciation of the Colombian Peso against the U.S. dollar on our U.S. dollar net asset position. In 2017 our exchange rate gain was COP$5,514 million, as compared to a gain of COP$976,430 million in 2016.

 

· A COP$688,664 million decrease in financial income corresponding to the reversal of a provision we had set aside in 2016 relating to a litigation concerning Santiago de las Atalayas (the “Comuneros”). See below and Note 23.3 to our consolidated financial statement for more detail.

 

· A COP$39,814 million increase in losses related to other minor financial items.

 

This increase in our financial loss was partially offset by: (i) the use of cash flow and net investment hedge accounting, which has allowed us to neutralize, overall, the effect of the exchange rate fluctuation on 71.2% of the U.S. dollar debt of Ecopetrol S.A., since exchange rate changes are recognized under other comprehensive income within equity, (ii) the efficient allocation of debt within the companies that make up the Ecopetrol Group, thereby achieving an approximately zero net position in U.S. dollars as of December 31, 2017, and (iii) a COP$379,030 million decrease in interest expenses as a result of: (i) the use of cash surpluses to pre-pay foreign currency-denominated loans totaling US$1,925 million in June 2017 and US$475 million in December 2017 and (ii) a decrease in interest on local currency-denominated loans with a lower interest rate indexed to the Consumer Price Index (CPI) and a decrease in interest on capital payments.

 

  77  

 

 

Finance results, net, amounted to a loss of COP$1,175,367 million in 2016 as compared to a loss of COP$7,663,104 million in 2015. This decrease in loss was mainly due to:

 

· The positive impact (COP$6,543,044 million) resulting from the depreciation of the Colombian Peso against the U.S. dollar on our U.S. dollar net asset position. Our 2016 exchange rate gain was COP$976,430 million, as compared to a loss of COP$5,566,614 million in 2015.

 

· The adoption of cash flow hedge accounting in October 2015 and the hedging of our net investment in June 2016 has allowed us to neutralize, overall, the effect of the exchange rate fluctuation over 88% of the U.S. dollar debt of Ecopetrol S.A., since exchange rate changes are recognized under other comprehensive income within equity.

 

· A COP$688,664 million increase in financial income corresponding to the reversal of a provision we had set aside relating to a litigation concerning the “Comuneros” (litigation concerning Santiago de las Atalayas). In November 2016, the Ministry of Mines and Energy concluded that the amounts being held were not royalties and therefore not due to the Comuneros. The amounts belonged to Ecopetrol and therefore Ecopetrol recovered the provision it had been recognizing in its financial statements relating to this dispute. See Note 23.3 to our consolidated financial statement for more detail.

 

· A COP$107,244 million increase in the valuation of our forward hedging operations used to mitigate the volatility of the exchange rate in the cash flow required for the operations of our subsidiary Ocensa, whose functional currency is the U.S. dollar.

 

· A COP$145,191 million increase in other minor financial items.

 

This decrease in our financial loss was partially offset by a COP$996,406 million increase in interest expenses as a result of (i) the recognition of Reficar’s interest expenses which, up to 2015, had been capitalized (ii) the aggregate US$475 million international loans we entered into in February and May 2016 and the US$500 million international bond we issued in June 2016, and (iii) the negative effect the Colombian Peso had on our exchange rate on interest due on our foreign debt.

 

For more details on our financial income and expenses see Note 29 to our consolidated financial statements for more details.

 

4.5.1.6        Income Tax

 

Income taxes amounted to COP$5,800,268 million in 2017, COP$4,543,046 million in 2016 and COP$710,353 million in 2015. The above is equivalent to an effective tax rate of 42.1%, 58.3% and -12.7% in 2017, 2016 and 2015, respectively.

 

The decrease in the effective tax rate from 2016 to 2017 was mainly due to: (i) the better financial performance of the exploration and production segment, (ii) the reduction of losses at Reficar and Ecopetrol America Inc, which also resulted in lower tax rates and (iii) the reduction of the wealth tax rate from 1% in 2016 to 0.4% in 2017.

 

The increase in the effective tax rate from 2015 to 2016 was mainly due to: (i) lower recovery of deferred tax asset, (ii) the effect of the adjustment in deferred tax resulting from the application of the Colombian tax reform described above, and (iii) the recognition of the presumptive tax on subsidiaries reporting tax losses.

 

See Note 10 to our consolidated financial statements for more details.

 

4.5.1.7        Net Income (Loss) Attributable to Owners of Ecopetrol

 

As a result of the foregoing, in 2017, net income attributable to owners of Ecopetrol was COP$7,178,539 million whereas, in 2016, net income attributable to owners of Ecopetrol was COP$2,447,881 million and, in 2015, net loss attributable to owners of Ecopetrol was COP$7,193,859 million.

4.5.1.9        Exploration and Production Segment Results

 

In 2017, exploration and production segment sales were COP$36,494,934 million, compared to COP$28,221,210 million in 2016. In 2017, our segment sales increased by 29.3% as compared with 2016 mainly as a result of:

 

· Increased sales of crude oil to third parties, which increased by 21.8% in 2017 as compared to 2016 primarily due to: (i) an increase in the price of our crude oil basket of US$12.1 per barrel, (ii) an increase in local sales of crude oil (1.3 mmbls) due mainly to sales of crude oil as a result of the Bicentenario alternative transport system which mitigated the effect of the attacks on the Caño Limon-Coveñas Oil pipeline. This increase was partially offset by: (i) a decrease of 7.7 mmbls in crude oil exports due to an increase in the use of local crude oil by Reficar for its operations, (ii) the appreciation of the Colombian Peso against the U.S. dollar resulting in a decrease in sales revenue recorded in U.S. dollars and (iii) a decrease of 0.9 mmboe in sales of natural gas mainly due to the end of the El Niño phenomenon in 2017, which reduced thermal generation by gas.

 

· Increased inter-segment revenues, which increased by 49.3% in 2017 as compared to 2016 mainly due to sales of crude oil in order to supply Reficar.

 

In 2016, exploration and production segment sales were COP$28,221,210 million, compared to COP$31,732,611 million in 2015. In 2016, our segment sales decreased by 11.1% as compared with 2015 mainly as a result of:

 

· Lower sales of crude oil to third parties, which decreased by 20% in 2016 as compared to 2015 primarily due to: (i) a decline of 36.8 mmbls in crude oil exports and volumes available for commercialization mainly due to the decrease in the production output and delivery of crude oil destined for exports to Reficar as feedstock (ii) a decrease in the price of our crude oil basket of US$8.2 per barrel, (iii) a decrease of 2.0 mmboe in sales of foreign natural gas mainly due to the termination of our Venezuela sales contract on June 30, 2015. Notwithstanding, the decrease in sales to third parties was partially offset by an increase in the devaluation of the Colombian Peso against the U.S. dollar and higher sales of crude oil and local natural gas, the latter resulting from an increase in the prices of the natural gas basket of US $2/barrel, which was indexed to 2015 prices and impacted by the “El Niño” weather phenomenon; and

 

· Higher inter-segment revenues, which increased by 26.9% in 2016 as compared to 2015 mainly due to sales of crude oil in order to supply Reficar.

 

Cost of sales affecting our exploration and production segment is mainly related to: (i) the amortization and depletion of our production assets, (ii) contracted services and (iii) costs related to maintenance, operational services, electric power, projects and labor in the exploration and production segment. In addition, this segment’s costs are impacted by the purchases of crude oil from ANH and third parties, naphtha for dilution and transportation services.

 

In 2017, the cost of sales for this segment increased by 14.5% as compared with 2016, due to the net effect of:

 

· Fixed costs increasing by 16.1%, or COP$1,115,851 million, in 2017 as compared to 2016, mainly due to (i) an increase in contracted services, maintenance and operating materials, which included preventative surface maintenance activities at our production facilities and well services as a strategy to mitigate natural decline rates and (ii) an increase in the costs of hydrocarbon transportation services as a result of paying for alternative routes to bypass the attacks on the Caño Limon-Coveñas oil pipeline. This increase was partially offset by a decrease in contracted services as a result of the full return of the Recetor field to Ecopetrol on May 30, 2017 and our full operation of the Rubiales field for the entire year.

 

  80  

 

 

· Variable costs increasing by 13.9%, or COP$2,221,585 million, in 2017 as compared to 2016, as a result of (i) an increase of purchases of crude oil due to the increase in international benchmark prices, (ii) higher depreciation, mainly as a result of the beginning of operations of the Gunflint field by Ecopetrol America Inc. in August 2016, (iii) a decrease in hydrocarbon proved developed reserves in 2016 as compared to 2015 which led to an increase in depreciation expenses, and (iv) higher transportation costs due to the use of alternate pipelines in order to transport the crude oil despite the attacks on the Caño Limon-Coveñas oil pipeline. This increase was partially offset by: (i) lower imports of fuels, especially diesel and gasoline, due to the replacement of imports with products produced by Reficar, lower diluent consumption, due to the strategy of marketing high-viscosity crudes and co-dilution with LPG use of products by Reficar rather than the use of imported products, and (ii) the positive effect of the appreciation of the Colombian peso against the U.S. dollar on our purchases in U.S. dollar.

 

In 2016, the cost of sales for this segment decreased by 10.6% as compared with 2015, due to the net effect of:

 

· Fixed costs decreasing by 3.7%, or COP$268,558 million, in 2016 as compared to 2015, mainly due to (i) a decrease in contracted services, maintenance and operating materials as a result of the cost efficiencies achieved by the transformation plan, which involved reduction of contract fees and optimization of maintenance timing without affecting operations, and (ii) a decrease in services contracted in association with partners as a result of the return of the Rubiales and Cusiana contracts to Ecopetrol in July 2016, showing the operational capacity and efficiency of the segment. This decrease was partially offset by an increase in the costs of hydrocarbon transportation services as a result of a ship or pay contract, indexed to the U.S. dollar, between the exploration, production, transportation and logistics segments.

 

· Variable costs decreasing by 13.3%, or COP$2,467,666 million, in 2016 as compared to 2015, as a result of (i) reduction in purchases of diluent as part of our cost efficiencies, strategy and lower production of heavy crude oil, (ii) lower volumes of crude oil purchases from the ANH, third parties and other products due to lower availability of crude oil due to lower production, (iii) lower transportation costs due to the optimization of the use of tanker trucks and savings due to the increase in viscosity for the transportation of heavy crude oil through pipelines, (iv) a decrease in services contracted in association with partners as a result of the return of the Rubiales and Cusiana contracts to Ecopetrol in July 2016, and (v) capitalization of inventories as a result of higher prices on purchases of crude oil, diluent in December 2016 compared to December 2015. This decrease was partially offset by an increase of electric power costs and process materials as chemicals and catalysts used in our direct operation of the Rubiales field and the increase in the average exchange rate of the Colombian Peso against the U.S. dollar (which led to increased costs in Colombian Peso terms).

 

In 2017, operating expenses before impairment of non-current assets increased by 7.8% in 2017 as compared to 2016, primarily as a result of (i) higher expenses related to our exploratory activity as we engaged in more seismic activity and recorded expenses related to exploratory activity at the Kronos-1, Parmer-1, Warrior 2, Lunera-1, Brama-1, Molusco-1, Godric, Dumbo and Pollera wells, (ii) the termination in 2016 of the deferred income amortization we had been recognizing since 2007 for the advance payment by the Ministry of Finance and Public Credit of the obligations under Ecogas, in relation to the Built, Operate and Transfer contracts (BOMT's) for the construction, operation, maintenance and transfer of gas pipelines. This increase was partially offset by (i) increased income due to the acquisition of an additional 11.6% interest at the K2 field in the Gulf of Mexico which generated a gain due to the increase in the book value of the asset above the value paid for the additional interest and (ii) the reduction of the wealth tax rate from 1% in 2016 to 0.4% in 2017.

 

In 2016, operating expenses before impairment of non-current assets decreased by 70.1% in 2016 as compared to 2015, primarily as a result of (i) lower expenses related to our exploratory activity as we engaged in less seismic activity and exploratory drilling, (ii) minor commissions, fees, freight and services as a result of the savings obtained in the implementation of our transformation plan, and (iii) a lower wealth tax. This decrease was partially offset by an increase in labor expenses due to the implementation of the voluntary retirement plan.

 

  81  

 

 

The net reversal of impairment of non-current assets recognized in the exploration and production segment in 2017 totaled COP$183,718 million as compared to an impairment loss of COP$196,448 million in 2016. The net reversal of the impairment was primarily due to the increased value of offshore oil fields, partially offset by an impairment of onshore fields, both as a result of calculating their valuation taking into account market variables, reserves, price spreads as compared to the ICE Brent price, and available technical and operational information.

 

The impairment losses of non-current assets   recognized in the exploration and production segment in 2016, which totaled COP$196,448 million compared to COP$4,504,495 million in 2015, decreased by 95.6% as compared to 2015 mainly due to variation in estimations of future prices which include the current scenarios of oil quota agreements of OPEC and the impact of changes on specifications issued by the IMO (International Maritime Organization) agreement on crude and fuels with high sulfur content (See Note 18.1 to our consolidated financial statements for more details).

 

The segment recorded net income attributable to owners of Ecopetrol of COP$3,820,501 million in 2017 as compared to net income attributable to owners of Ecopetrol of COP$1,322,370 million in 2016 and net loss attributable to owners of Ecopetrol of COP$5,851,619 million in 2015.

 

Lifting and Production Costs

 

The aggregate average production cost, on a Colombian Peso basis, has increased to COP$23,684 per boe during 2017 from COP$20,993 per boe during 2016. On a dollar basis, our aggregate average production cost increased to US$8.02 per boe in 2017 from US$6.88 per boe in 2016, due partially to a 3.27% appreciation of the average exchange rate of the Colombian Peso against the U.S. dollar in 2017.

 

The aggregate average lifting cost, on a Colombian Peso basis, increased to COP$22,585 per boe during 2017 from COP$19,799 per boe during 2016. On a dollar basis, it increased to US$7.65 per boe in 2017 from US$6.49 per boe in 2016 also due partially to the 3.27% appreciation of the average exchange rate of the Colombian Peso against the U.S. dollar in 2017.

 

The abovementioned increases were primarily due to:

 

· Higher costs at both the Rubiales and Cusiana fields due to their full return to Ecopetrol at the beginning of the third quarter of 2016;

 

· Higher costs at the Recetor field due to its full return to Ecopetrol on May 30, 2017;

 

· An increase in costs related to subsoil maintenance, which in turn was due to an increase in the number and complexity of well interventions and services, which have managed to maintain and improve the basic production curve;

 

· An increase in costs related to surface maintenance, which in turn was due to an increase in the number of intervened surface equipment, which has managed to maintain the operational reliability and integrity of the surface equipment in production operations;

 

· An increase in energy costs, which in turn was due to an increase in water production in fields, mainly in the Meta region and incorporation of assets in the Rubiales field with a higher water cut (+ 98% BSW);

 

· An increase in costs related to chemical treatment of fluids, which in turn was due to an increase in the volume of water production in fields under our direct and indirect operation; and

 

· An increase in water treatment, that increases energy consumption and fluid treatment given the utilization of injection technique for water disposal and recovery projects.

 

  82  

 

 

The difference between the aggregate average lifting cost and aggregate average production cost is that lifting cost does not include the costs related to hydrocarbon self-consumption required in the production process or the deliveries we make to our refineries and natural gas liquid plants.

 

The following table sets forth crude oil and natural gas average sales prices, the aggregate average lifting costs and aggregate average unit production cost for the years ended December 31, 2017, 2016 and 2015.

(1) Corresponds to our average sales price on a consolidated basis.
(2) Unit production costs correspond to consolidated average costs on total production volumes net of royalties. Production costs do not include costs related to transport, commercialization and administrative expenses.
(3) Lifting costs per barrel are calculated based on total production (excluding production tests and discovered undeveloped fields), which are net of royalties, and correspond to our lifting costs on a consolidated basis.
(4) The cost indicator is calculated by using the cost of production (does not include costs related to hydrocarbons consumption by Ecopetrol in the production process, such as by our refineries and natural gas liquid plants) and dividing by the net produced volume (excluding royalties) as the denominator.
(5) As a result of the evaluation of control over companies under IFRS, Ecopetrol does not consolidate Savia Perú and Equion.

 

4.5.1.10        Transportation and Logistics Segment Results

 

In 2017, our transportation and logistics segment sales were COP$10,598,064 million compared to COP$10,648,776 million in 2016. The 0.5% decrease in 2017 as compared with 2016 was mainly due to (i) a 5% decrease in the volume of crude oil transported by our pipelines, which was primarily due to the production decrease at the national level and (ii) the negative effect on our U.S. dollar-indexed transportation fees resulting from the appreciation of the Colombian Peso against the U.S. dollar. This decrease was almost offset by a 1.9% increase in the volume of refined products transported primarily due to the increase in demand for refined products in Colombia and the elimination of restrictions in the Pozos Colorados - Galán system. Sales to third parties decreased in 2017 as compared to 2016 primarily due to the fact that the segment received income from the transportation services to Frontera Energy for its participation in the Rubiales field, and once the field returned to us in July 2016, these services were recognized as inter-segment sales.

 

In 2016, our transportation and logistics segment sales were COP$10,648,776 million compared to COP$10,844,550 million in 2015. The 1.8% decrease in 2016 as compared with 2015 was mainly due to an 11.3% decrease in the volume of crude oil transported by our pipelines, which was primarily due to the production decrease at the national level, in spite of (i) the positive effect on our U.S. dollar-indexed transportation fees resulting from the devaluation of the Colombian Peso against the U.S. dollar and (ii) a 3.7% increase in the volume of refined products transported in the Galán-Sebastopol system to meet the demand for fuel in Colombia and the start-up of Reficar. Sales to third parties decreased in 2016 as compared to 2015 primarily due to the fact that the segment received income from the transportation services to Pacific Rubiales for its participation in the Rubiales field, and once the field returned to us in July 2016, these services were recognized as inter-segment sales.

 

The cost of sales for our transportation and logistics segment is mainly related to: (i) project costs associated with the maintenance of transportation networks and (ii) operating costs related to these systems, including the costs of labor, energy, fuels and lubricants and others.

 

  83  

 

 

The cost of sales amounted to COP$3,271,835 million in 2017 as compared to COP$3,349,791 million in 2016. The cost of sales for this segment decreased by 2.3% in 2017 as compared with 2016 mainly due to a decrease in costs associated with maintenance, operating supplies and materials due to the continuity of our efficiency program to optimize our operating costs. This decrease was partially offset by (i) an increase in material processing costs needed for power generation in three new pumping stations to operate Ocensa’s P135 project and (ii) an increase in depreciation resulting from the start of P135.

 

The cost of sales amounted to COP$3,349,791 million in 2016 as compared to COP$3,744,422 million in 2015. The cost of sales for this segment decreased by 10.5% in 2016 as compared with 2015 mainly due to a decrease in costs associated with maintenance, operating supplies and materials due to the continuity of our efficiency program to optimize our operating costs. This decrease was partially offset by an increase in material processing costs needed for power generation in pumping stations and an increase in depreciation due to a higher level of investments in the segment.

 

In 2017, operating expenses before the impairment of non-current assets decreased by 15.1% as compared to 2016 due to lower administrative expenses mainly as a result of the consolidation of administration areas within the segment and a decrease in taxes because of the reduction of the wealth tax rate discussed previously.

 

In 2016, operating expenses before the impairment of non-current assets increased by 30.7% as compared to 2015 due to a recovery of environmental provisions in 2015, no similar recoveries in 2016 and an increase in labor costs as a result of the implementation of the voluntary retirement plan. This increase was partially offset by lower wealth and industry taxes.

 

The net reversal of impairment of non-current assets recognized in the segment in 2017, totaled COP$59,455 million in 2017 as compared to an impairment recovery of COP$41,062 million in 2016. The net reversal of the impairment was due to the inclusion, in the assessment of the recovery amount of this segment’s assets, of flows associated with the Port of Tumaco that positively affects the recoverable amount of the southern transportation unit (See Note 18.3 to our consolidated financial statements for more detail).

 

The impairment recovery of non-current assets recognized in the segment in 2016 totaled COP$41,062 million in 2016 as compared to COP$81,388 million loss in 2015, a decrease of 150.5% as compared to 2015 mainly due to the incorporation, in the assessment of the recovery amount of this segment’s assets, of flows associated to the San Fernando - Apiay system project that affects the recoverable amount of the Llanos transportation line, partially offset by an increase in impairment of assets related to the southern transportation line.

 

The segment recorded net income attributable to owners of Ecopetrol of COP$2,999,978 million in 2017 as compared to net income of COP$2,960,449 million in 2016 and COP$2,819,759 million in 2015.

 

4.5.1.11        Refining and Petrochemicals Segment Results

 

In 2017, the refining and petrochemical segment sales were COP$28,644,016 million compared to COP$24,823,714 million in 2016. In 2017, sales of refined products and petrochemicals increased by 15.4% as compared with 2016, mainly due to an increase of our average products basket price due to the increase in the international prices. This increase was partially offset by (i) a decrease in exports of fuel oil primarily due to reduced production at the Barrancabermeja refinery as a result of reliance on more efficient alternative sources and stabilization of the coker unit at Reficar and (ii) a decrease in exports of diesel due to our commercial strategy of focusing on selling to the domestic market due to better commercial conditions, replacing lace imports of such products.

 

In 2016, the refining and petrochemical segment sales were COP$24,823,714 million compared to COP$23,245,676 million in 2015. In 2016, sales of refined products and petrochemicals increased by 6.8% as compared with 2015, mainly due to an increase in the volume of domestic and export sales mainly in mid-distillates due to the startup of operations at Reficar. This increase was partially offset by a decrease of our average products basket price due to the decrease in the international price of crude oil.

 

  84  

 

 

The cost of sales for our refined products and petrochemicals segment is mainly related to the purchase of crude oil and natural gas for our refineries, imported products to supply local demand, feedstock transportation services, services contracted for maintenance of the refineries and the amortization and depreciation of refining assets. Cost of sales amounted COP$26,855,395 million in 2017, compared to COP$22,843,987 million in 2016 and COP$20,758,808 million in 2015.

 

In 2017, the cost of sales for this segment increased 18% as compared with 2016, principally due to (i) an increase in purchases of crude oil at increased international benchmark prices and (ii) higher volumes of imports of crude oil and inter-segment purchases of crude oil for Reficar. This increase was partially offset by lower imports of other fuels, especially diesel and gasoline, due to the use of products produced by Reficar rather than imported products.

 

In 2016, the cost of sales for this segment increased 10% as compared with 2015, principally due to the operation of Reficar’s units in 2016 which led to (i) an increase in crude oil purchases through import and inter-segment transactions as Reficar required a special feedstock during the stabilization and performance testing period which increased production cost, (ii) an increase in the depreciation of Reficar’s units (iii) inventory consumption that had been in stock in December 2015, and (iv) higher costs for services contracted, materials of process, maintenance and electrical power. This increase was partially offset by lower imports of products and the excellent operational performance of the Barrancabermeja refinery.

 

In 2017, operating expenses before the impairment of non-current assets decreased by 17.2% as compared to 2016, due a decrease of stabilization expenses of Reficar and a decrease in taxes because of the reduction of the wealth tax rate.

 

In 2016, operating expenses before the impairment of non-current assets increased by 27.3% as compared to 2015, due to an increase in labor expenses related to our voluntary retirement plan in 2016 and other expenses related to the start-up of operations at Reficar.

 

The net reversal of impairment of non-current assets recognized in the segment in 2017, which totaled COP$1,067,965 million in 2017 as compared to an impairment loss of COP$773,361 million in 2016, decreased as compared to 2016 as a result of (i) a net reversal of the impairment of Reficar as a result of an improved outlook in refining margins due to the anticipated effects of the ratification of the International Convention for the Prevention of Pollution from Ships (Marpol), which goes into effect in 2020, (ii) a lower discount rate resulting from the application of WACC methodology and (iii) operational and financial optimization due to the stabilization of the refinery. This reversal was partially offset by Bioenergy’s impairment related to the change of the project start date, the process of stabilization of the industrial plant, the updating of operational variables and the financial expenses of the Barracabermeja refinery’s modernization project, which is currently postponed.

 

The impairment losses of non-current assets recognized in the segment in 2016, which totaled COP$773,361 million as compared to COP$3,278,993 million in 2015, decreased by 76.4% as compared to 2015. The 2016 scenario incorporated refining margins including the effect of Marpol in 2016 compared to 2015, partially offset by the effect of adjustment of operational variables based on that observed during Reficar’s stabilization period and new ethanol prices on Bioenergy’s impairment (See Note 18.2 to our consolidated financial statements for more details).

 

As mentioned earlier, the refining segment is highly sensitive to changes in product prices and feedstock in the international market, the discount rate, the refining margins, changes in environmental regulations and cost structure and the level of capital expenditures.

 

The refining and petrochemicals segment recorded net income attributable to owners of Ecopetrol of COP$358,859 million in 2017, as compared to a net loss attributable to owners of Ecopetrol of COP$1,823,020 million in 2016 and COP$4,016,050 million in 2015.

 

4.6        Liquidity and Capital Resources

 

Our principal source of liquidity in 2017 was cash flows from our operations amounting to COP$16,973,626 million.

4.6.1        Review of Cash Flows

 

Cash from operating activities

 

Net cash provided by operating activities increased by 19.3% in 2017 as compared to 2016, mainly as a result of (i) a 32.7% increase in our operational income before depreciation, depletion and amortization (DD&A) and impairment of non-current assets and efficiency gains and cost-savings generated by our corporate strategy. This increase was partially offset by (i) higher working capital needs mainly due to increase in accounts receivable from the FEPC and commercial receivables accounts and (ii) an increase in our costs due to the effect of recovery in international crude oil prices on our purchases and an increase in maintenance activities, contracted services and operating supply needs associated with an increase in our operational activities.

 

Net cash provided by operating activities increased by 21.9% in 2016 as compared to 2015, mainly as a result of (i) lower working capital needs mainly due to the higher oil prices observed at the end of 2016 versus the end of 2015, (ii) a 4% increase in our operational income before depreciation, depletion and amortization (DD&A) and impairment of non-current assets resulting from a decrease in our costs and operational expenses (before DD&A and impairment) due to our savings generated by the transformation plan. This increase was partially offset by (i) the decrease in international prices of crude oil during 2016, and (ii) an increase in income tax paid by the transportation and logistics segment due to the better results in 2015.

 

Cash used in investing activities

 

In 2017, net cash used in investing activities decreased by 53.3% as compared to 2016, mainly as a result of a 110.4% decrease in our investment portfolios as a result of pre-payments of foreign currency-denominated loans totaling US$2,400 million in 2017. This decrease was partially offset by (i) cash proceeds from the sale of our shares in Empresa de Energía de Bogotá, which totaled COP$56,930 million in the aggregate and (ii) a 4.6% increase in investments in capital expenditures, which was driven mainly by the reactivation of activity in our Castilla and Rubiales fields, the development of improved recovery projects in fields such as La Cira and Chichimene, and an increase in exploration activities.

 

In 2016, net cash used in investing activities decreased by 26.8% as compared to 2015, mainly as a result of: (i) a 62.4% decreased investment in capital expenditures due to the effect of decreasing oil prices and the conclusion of the Reficar modernization project, and (ii) additional cash proceeds from the sale of our investments in Empresa de Energía de Bogotá and Interconexión Electrica S.A., which totaled COP$966,715 million in the aggregate. This decrease was partially offset by increased investments of our excess liquidity in our investment portfolios, which in turn resulted from the savings we achieved and the recovery of the price of oil during the second half of 2016.

 

Cash used in financing activities

 

Net cash used in financing activities increased by 362% in 2017, as compared to 2016, due to (i) prepayments of foreign currency-denominated loans totaling US$2,400 million and (ii) an increase in dividends payments to the shareholders of Ecopetrol of COP$255,484 million in 2017 as compared to 2016, which was partially offset by a COP$463,135 million decrease in dividend payments made by certain of our subsidiaries to their non-controlling shareholders.

 

  86  

 

 

Net cash used in financing activities increased by 98.5% in 2016, as compared to 2015, due to a decrease in cash from borrowings of COP$5,151,937 million which was partially offset by a decrease in dividends payments of COP$3,781,099 million in 2016 as compared to 2015.

 

4.6.2        Capital Expenditures

 

Our consolidated capital expenditures in 2017, 2016 and 2015 were COP$6,107,506 million, COP$5,837,477 million and COP$15,517,949 million, respectively. These investments were distributed by business segment on average, for the past three years as follows: 64.9% for the exploration and production segment, 17.4% for refining and petrochemicals and 17.7% for the transportation and logistics segment. See Note 33.3 to our consolidated financial statements for more detail about capital expenditures by segment.

 

Our investment plan approved for 2018 is a range of between US$3,500 million and US$4,000 million. The investments will be distributed approximately as follows: 85% for exploration and production, 14% for refining, petrochemicals, and transportation and logistics, and 1% for other investments.

 

The resources required for the investment plan will be funded through internal cash generation with no need to raise additional net financing.

 

4.6.3        Dividends

 

In 2017, we paid dividends of COP$945,661 million to Ecopetrol’s shareholders, including the Nation, and dividends paid to non-controlling shareholders of our subsidiaries totaling COP$558,986 million.

 

In 2016, we paid the last installment of dividends relating to 2014 net income to the Nation for COP$690,177 million and our transportation and logistics subsidiaries paid dividends to their non-controlling shareholders for COP$1,022,121 million. Given the net loss we reported in 2015, our shareholders at the ordinary general shareholder’s meeting did not approve distribution of dividends for 2015.

 

On March 23, 2018, our shareholders at the ordinary General Shareholders Assembly approved a distribution of dividends for the fiscal year ended December 31, 2017 amounting to COP$3,659,386 million, or COP$89 per share, based on the number of outstanding shares as of December 31, 2017. The dividend payment was approved to be made in one installment for the minority shareholders of Ecopetrol on April 19, 2018 and two installments for the Nation, the first paid on April, 19 2018 and the second installment to be paid on September, 17 2018.

 

4.7        Summary of Differences between Internal Reporting (Colombian IFRS and IFRS)

 

We prepare our interim and annual statutory financial information in accordance with our internal reporting policies, which follow Colombian IFRS and differ in certain significant aspects from IFRS. The following table sets forth our consolidated net income and equity for years ended December 31, 2017, 2016 and 2015, in accordance with Colombian IFRS and IFRS:

  87  

 

 

As noted above, certain differences exist between our net income and equity as determined in accordance with our internal reporting policies, which follow Colombian IFRS, which are used for management reporting purposes, as presented in the business segment information, and our net income and equity as determined under IFRS, as presented in our consolidated financial statements.

 

The primary differences between Colombian IFRS and IFRS as they apply to our results of operations are summarized below:

 

Cash flow hedge for future company exports . In September 2015, in order to hedge the effect of exchange rate volatility on Ecopetrol’s foreign currency debt, Ecopetrol’s Board of Directors approved a cash flow hedge for future crude oil exports. According to IAS 39 – Financial Instruments, Ecopetrol implemented this hedge beginning on October 1, 2015, the date on which it formally completed the related hedging documentation.

 

Under Colombian IFRS, the General Accounting Office of the Nation (CGN for its acronym in Spanish) issued Resolution 509, which allows companies to apply hedge accounting for non-derivative financial instruments from any date within the transition period or the first period of application of International Accounting Standards in Colombia, even if such company has not yet formally documented the hedging relationship, the objective or the risk management strategy. Under these rules, Ecopetrol applied cash flow hedge accounting from January 1, 2015 in its financial statements under Colombian IFRS.

 

As a result of this accounting policy difference, for the year ended December 31, 2017, our net income as reported under IFRS was COP$366,048 million higher than our net income as reported under Colombian IFRS.

 

Exchange rate effects on tax bases – Deferred tax . According to IAS 12.41, companies with a U.S. dollar functional currency and profit or tax loss in Colombian Pesos are required to recognize deferred taxes attributable to the difference between the carrying amounts of non-monetary assets in their financial statements and their respective tax bases converted from Colombian Pesos to U.S. dollars using the exchange rate on the closing date. The effect of the temporary difference is charged to profit and losses without a cash outflow expected in the future. Under local accounting principles (The General Accounting Office opinion No. 20162000000781 dated January 18, 2016), the result attributable to the aforementioned difference in accounting policies does not generate deferred taxes at December 31, 2017.

 

Ecopetrol’s functional currency is the Colombian Peso and it consolidates some subsidiaries whose functional currency is the U.S. dollar but who settled their taxes in Colombian Pesos. As a result of the application of paragraph 41 – IAS 12, such subsidiaries are required to calculate deferred taxes under IFRS.

 

As a result of this accounting policy difference, for the year ended December 31, 2017, our net income attributable to owners of Ecopetrol as reported under IFRS was COP$192,079 million higher than our net income attributable to owners of Ecopetrol as reported under Colombian IFRS.

 

The application of IAS12.41 also generated adjustments to our goodwill and investments in companies impairments of COP$61,893 million in 2017, COP$86,781 million in 2016 and COP$418,872 million in 2015 in connection with our purchase of subsidiaries whose functional currency is the U.S. dollar as well as adjustments to our revenue from the equity method of COP$60,748 million in 2017, COP$71,056 million in 2016 and COP$81,808 million in 2015 in connection with our associates and joint ventures whose functional currency is the U.S. dollar.

 

As a result of these accounting policy differences described above, for the year ended December 31, 2017, we reported net income attributable to the owners of Ecopetrol under IFRS of COP$7,148,539 million as opposed to a net income attributable to the owners of Ecopetrol of COP$6,620,412 million reported under Colombian IFRS for the same period. For the year ended December 31, 2016, these same accounting differences led us to report net income attributable to the owners of Ecopetrol under IFRS of COP$2,447,881 million as opposed to a net income attributable to the owners of Ecopetrol of COP$1,564,709 million reported under Colombian IFRS for the same period. For the year ended December 31, 2015, these same accounting differences led us to report a net loss under IFRS of COP$7,193,859 million as opposed to a net loss of a COP$3,987,726 million reported under Colombian IFRS for the same period.

  89  

 

 

The long term debt balance for the end of 2017 is explained as follows:

 

· On June 30, 2017, Ecopetrol repaid in advance its entire syndicated bank loan contracted with international banks in 2015. The loan had a nominal value of US$ 1,925 million which was originally due on February 2020.

 

· On August 14, 2017, Ecopetrol signed a committed line with a local bank for COP$ 990 billion as a contingent financing mechanism. This facility has 2 year availability period, a maturity of 10 years from the date of the first disbursement, 2 years grace period on capital, an interest rate of IBR + 300 basis points and a commitment fee of 7.2 basis points annually on the undisbursed amount during the availability period.

 

· On December 13, 2017, Ecopetrol voluntarily assumed Reficar´s debt obtained for the refinery modernization (approximately US$2,666 million in nominal terms plus accrued interest). The debt assumption was under the same financial conditions that Reficar originally had. This transaction had no effect on Ecopetrol´s consolidated debt level.

 

· On December 15, 2017, Ecopetrol repaid in advance its loans with The Bank of Tokyo-Mitsubishi UFJ, Ltd. and Export Development Canada, with nominal values of US$175 million and US$300 million, respectively. The original due date for those facilities was 2021.

 

· Ecopetrol did not disburse any long-term debt in 2017.

 

On April 13, 2018, Ecopetrol redeemed all of its outstanding 4.250% notes due September 18, 2018 in an aggregate principal amount of US$350 million. The notes were issued in September 2013.

4.10        Trend Analysis and Sensitivity Analysis

 

Trend Analysis

 

Ongoing Trends

 

Ecopetrol updated its 2020 Business Plan on September 29, 2016. This Plan is based on three fundamental pillars: i) protection of cash and cost efficiency; ii) strict capital discipline; and iii) growth in reserves and production; these pillars will strengthen the Company’s financial sustainability and afford it opportunities for both organic and inorganic growth, generating value and profitability for its shareholders.

 

According to this business plan, during 2018 the Company will continue to pursue its transformation to ensure operational and financial sustainability. It will focus on multi-year fields development plans; improved return on assets; committing ourselves to integrity, safe operations, environment consciousness and joint prosperity with communities in which we operate and execute projects.

 

We believe that our strategy of diversifying our export destinations and sales under term contracts with fixed discounts to reference prices will help to mitigate the impact of crude oversupply over the spread of our export basket.

 

Furthermore, with the full operation of all of the units of Reficar since 2016 and shifting from stabilization to optimization, Ecopetrol’s trade balance is expected to continue improving due to the reduction of gasoline imports and incremental exports of fuels. Reficar’s fuels production is expected to continue being allocated primarily in the domestic market, with a surplus to be exported.

 

Adding profitable reserves and maintaining the pace of production are the Company’s priorities. The exploration campaign will be focused in regions with strong prospects. Investment in exploration will be approximately US$400-US$450 million, allocated mainly to the evaluation and appraisal of discoveries and ongoing exploration efforts of Ecopetrol S.A., Hocol, Ecopetrol America Inc., Ecopetrol Mexico, Ecopetrol Costa Afuera and Ecopetrol Brazil.

 

We stress that a strong cash position allows us to assess opportunities for inorganic growth of Ecopetrol’s reserves.

Assumptions for the Sensitivity Analysis of our Results

 

· Our sensitivity analysis is based on the Consolidated Statement of Profit or Loss for 2017, as presented elsewhere in this annual report.

 

· The sensitivity of the ICE Brent price index is in reference to an increase of US$1 per barrel of crude oil in the average ICE Brent reference price based on a 365-day year for 2017. Prices assumed correspond to realized prices for crude oil, natural gas and refined products for 2017, adjusted to account for the differences between such realized prices and the ICE Brent reference price.

 

· The sensitivity of our results to changes in the exchange rate is in reference to a 1% average depreciation of the Colombian Peso against the U.S. dollar during 2017. Prices are the realized prices of crude oil, natural gas and refined products in 2017 and are expressed for the sensitivity using the adjusted exchange rate (i.e. a 1% average depreciation of the Colombian Peso against the U.S. dollar during 2017).

 

· The income tax for each of our sensitivity analyses (price of ICE Brent and COP$/US$ exchange rate) is estimated using the effective corporate tax rate of 42% for 2017.

5. Risk Review

 

5.1        Risk Factors

 

The risks discussed below could have a material adverse effect, separately or in combination, on our business’s operating results, cash flows, liquidity and financial condition. Investors should carefully consider these risks.

 

5.1.1        Risks Related to Our Business

 

This section describes the most significant potential risks to our business.

 

Our crude oil and natural gas reserve estimates involve some degree of uncertainty and may prove to be incorrect over time, which could adversely affect our ability to generate revenue.

 

Reserves estimates are prepared using generally accepted geological and engineering evaluation methods and procedures. Estimates are based on geological, topographical and engineering facts. Actual reserves and production may vary materially from estimates shown in this annual report, and downward revisions in our reserve estimates could lead to lower future production which could affect our results of operations and financial condition.

 

Hydrocarbon reserves presented in this annual report were calculated in accordance with SEC regulations. As required by those regulations, reserves were valued based on the unweighted average of closing prices for the first day of each month in the 12-month periods ended December 31, 2017, 2016 and 2015, as well as other conditions in existence at those dates. The average of closing prices of ICE Brent crude oil for the first day of each month in the 12-month period was US$55.57 per barrel in 2015, US$44.49 per barrel in 2016 and US$54.93 per barrel in 2017. In 2016, the Company recognized a reduction in oil and gas proven reserves of 14% in 2016 as compared to 2015, to 1,598 mmboe in 2016 from 1,849 mmboe in 2015. In 2017, the Company recognized an increase in oil and gas proven reserves of 4% as compared to 2016, to 1,659 mmboe in 2017 from 1,598 mmboe in 2016. For more information, see the section Business Overview—Exploration and Production—Reserves .

 

Furthermore, at least once a year, or more frequently if the circumstances require, the Company ascertains whether there are signs of impairment to its assets or cash-generating units (CGUs) due to the difference between the carrying amount of such assets or CGUs as opposed to their recoverable amounts, using reasonable assumptions, based on internal and external factors, which reflect market conditions. The recoverable amount is considered to be the higher of the fair value minus costs of disposal and value in use, based on the free cash flow method, discounted at the weighted average capital cost (WACC). Whenever the recoverable amount of an asset or CGU is lower than its net carrying amount, such amount is reduced to its recovery amount, recognizing a loss for impairment as an expense in the consolidated statement of profit or loss. External and internal sources of information may indicate that an impairment loss recognized for an asset, other than goodwill, may no longer exist or may have decreased, in this case, the reversal is recognized a gain for impairment in the consolidated statement of profit or loss.

 

  93  

 

 

In 2017, Ecopetrol had a COP$1,311,138 million net reversal of impairments recorded in previous years primarily as a result of improved hydrocarbon prices outlook, incorporation of new reserves, Ecopetrol’s crude oil basket price discount as compared to the ICE Brent crude oil price, improved refining margins outlook and technical operational capacity, among other factors. For additional information about this impairment charges, see Note 18 to our consolidated financial statements.

 

Any significant change in estimates and judgments could have a material effect on the quantity and present value of our proved reserves and subsequently on the recognition or recovery of impairment charges. Changes to estimations of reserves are applied prospectively to the amounts of depreciation, depletion and amortization charged and, consequently, the carrying amounts of exploration and production assets.

 

In order to assess the possible impact of current expected oil price scenarios and market conditions, as well as of further developments driven by the economic environment for the oil and gas industry, the Company has performed a sensitivity analysis over its proved reserve balance as of December 31, 2017. Based on these calculations, assuming an average price per barrel of ICE Brent crude oil of US$55 per barrel in 2018, US$60 per barrel in 2019, US$65 in 2020, US$70 in 2021 and US$75 per barrel for later years, Ecopetrol could recognize an increase in oil and gas proved reserves of approximately 3.3%. This analysis takes into account Ecopetrol’s estimates and expectations regarding the main assumptions used in its proven reserve calculation, which final actual result may fluctuate and differ substantially from those provided herein due to several factors outside of the control of the Company. For additional information see the section Financial Review—Trend Analysis and Sensitivity Analysis .

 

On the contrary, any downward revision in our estimated quantities of proved reserves would indicate lower future production volumes, which could result in higher expenses for depreciation, depletion and amortization for properties to which we apply the units of production method for calculating these expenses. These higher expenses, and any lower revenues as a result of actual production volumes and realized prices, could adversely impact our results of operations and financial condition.

 

Achieving our long-term growth depends on our ability to execute our strategic plan — specifically, the discovery and successful development of additional reserves.

 

Our long-term growth objectives depend largely on our ability to discover and/or acquire new reserves, and in turn developing them successfully and improving the recovery factor in our mature oil fields. Our exploration activities expose us to the inherent geological and drilling risks including the risk of not discovering commercially viable crude oil or natural gas reserves; and the risk that some exploratory wells initially budgeted for may be drilled at a later stage or not be drilled at all. Despite the effort we make to control costs associated with drilling, these are often uncertain, and numerous factors beyond our control may cause drilling operations to be curtailed, delayed or cancelled.

 

Our ability to add and develop reserves also depends on our capacity to structurally reduce costs to maintain the profitability of oil fields already being exploited.

 

If we are unable to successfully discover and develop additional reserves, or if we do not acquire properties having proved reserves, our reserves portfolio will decline. Failure to secure additional reserves may impede us from achieving or maintaining production targets, and may have a negative impact on our results of operations and financial condition.

 

See the section Strategy and Market Overview—Our Corporate Strategy for a discussion of our strategic plan.

Our business depends substantially on international prices for crude oil and refined products. The prices for these products are volatile; a sharp decrease could adversely affect our business prospects and results of operations.

 

In 2017, in Ecopetrol, approximately 92.4% of the revenues came from sales of crude oil, natural gas and refined products and 87% of the total volume sold of these products is indexed to international reference prices or benchmarks such as ICE Brent. Consequently, fluctuations in those international indexes have a direct effect on our financial condition and results of operations.

 

Prices of crude oil, natural gas and refined products have traditionally fluctuated as a result of a variety of factors including, among others, competition within the international oil and natural gas industry; long-term changes in the demand for crude oil (as further explained below), natural gas and refined products; the economic policies in the United States, China and the European Union; regulatory changes; changes in global supply, such as the current market conditions shifting from oversupply to a balanced crude oil market; inventory levels; changes in the cost of capital; adverse or favorable economic conditions; global financial crises; development of substitute sources of energy, development of new technologies; global and regional economic and political developments in the Organization of the Petroleum Exporting Countries, (OPEC); the willingness and ability of the OPEC and its members to set production levels; local and global demand and supply for crude oil, refined products and natural gas; trading activity in oil and natural gas, which thereby affects their respective margins; derivative financial instruments related to oil and gas; development or availability of alternative fuels; weather conditions; natural events or disasters; and terrorism and global conflict. In 2017, demand grew faster than supply, reducing crude oil inventories to almost a five year average, leveraged in stronger than expected economic growth in OECD countries and the extension of OPEC and Russia’s production cut agreement.

 

When crude oil, refined products and natural gas prices are low, we earn less revenue and we generate lower cash flow and less income. Conversely, when crude oil, refined product and natural gas prices are high, we earn more and generate a larger amount of cash and net income. During 2017, our crude oil basket price was US$47.8 per barrel versus US$35.7 in 2016; the refined product basket price was US$62.7 per barrel versus US$50.1 per barrel in 2016; and the natural gas price was US$22.7 per barrel equivalent in 2017 versus US$23.5 per barrel equivalent in 2016. However, it is important to consider that the margin on refined products can result either in higher or lower margins due to a change in price of crude the same way gas prices can be impacted by local conditions, such as local demand and weather conditions.

 

In 2017, we had a COP$1,311,138 net reversal of the impairment of non-current assets, as compared to the impairment of non-current assets of COP$928,747 million in 2016 and COP$7,864,875 in 2015. These impairments are an accounting effect that does not involve any disbursement of resources and they are susceptible to reversion when the fair value of the asset exceeds its book value. For additional information about this impairment charges, see the section Financial Review—Operating Results—Consolidated Results of Operations—Impairment of non-current assets and Note 18 to our consolidated financial statements.

 

A reduction of international crude oil prices could also result in a delay or a change in our capital expenditure plan, in particular delaying exploration and development activities, thereby delaying the development of reserves and affecting future cash flows. In order to maintain a profitable operation and preserve the cash flow of the Company at certain oil price levels, some of our producing fields may have to be closed or their operations temporarily suspended which would affect our production levels and expected revenues.

 

Changes in the Colombian Peso/U.S. dollar exchange rate could have an adverse effect on our financial condition and results of operations given the amount of U.S. dollar denominated debt held by the company and the fact that most of our revenues are derived from sales of products quoted in or with reference to U.S. dollars.

 

Most of our revenues are derived from sales of products quoted in or with reference to U.S. dollars. Therefore when the Colombian Peso depreciates against the U.S. dollar, our revenues converted into Colombian Pesos, increase. Conversely, when the Colombian Peso appreciates against the U.S. dollar, our revenues decrease.

 

On the other hand, imported goods, oil services and the debt, which is mainly denominated in U.S. dollars, become less expensive when the Colombian Peso appreciates against the U.S. dollar and more expensive when the Colombian Peso depreciates against the U.S. dollar.

 

  95  

 

 

As of December 31, 2017 our U.S. dollar-denominated total debt was US$12.6 billion, which we recognize in our consolidated financial statements at its amortized cost, which corresponds to the present value of cash flows, discounted at the effective interest rate. Out of this total, US$12.0 billion relate to Ecopetrol S.A., whose functional currency is the Colombian Peso. Therefore, when the Colombian Peso depreciates against the U.S. dollar, Ecopetrol S.A. is exposed to an exchange rate loss. In contrast, when the Colombian Peso appreciates against the U.S. dollar, Ecopetrol S.A.is exposed to an exchange rate gain. Some of the Group’s affiliates have the U.S. dollar as functional currency and are not exposed to a material exchange rate risk resulting from fluctuations in the Colombian Peso against the U.S. dollar. On the asset side, when the financial statements of the Group are consolidated, the exchange rate differential of the affiliates’ assets and liabilities whose functional currency is the U.S. dollar is recognized directly in the equity, as part of the other comprehensive income.

 

The Company adopted hedge accounting as part of its risk management strategy, using two types of natural hedges with its U.S. dollar debt as a financial instrument: i) cash flow hedge for exports of crude oil and ii) hedge of a net investment in a foreign operation. As a result of the implementation of both hedges, $8,532 million of Ecopetrol S.A.’s debt in U.S. dollars as of December 31, 2017, was designated as a hedge. With the adoption of hedge accounting, the effect of the volatility of the foreign exchange rate on the hedged portion of the debt is recognized directly in equity, as part of other comprehensive income. The remaining portion of Ecopetrol S.A.’s U.S. dollar-denominated debt as well as the financial assets and liabilities denominated in foreign currency continues to be exposed to the fluctuation in the exchange rate.

 

The U.S. dollar/Colombian Peso exchange rate has fluctuated during the last several years.  On average, the Colombian Peso depreciated 37.28% against the U.S. dollar in 2015, 11.18% in 2016 and appreciated 3.35% in 2017. Additionally, as of December 31, 2017, the Colombian Peso appreciated 0.56%, as of December 31, 2016, the Colombian Peso appreciated 4.72%, and as of December 31, 2015 it depreciated 31.64%, in each case from year-end exchange in the previous year. In addition, given the performance of interest rates in the U.S., crude oil prices in the next few years and political uncertainty in Colombia, there is no clear view of how the U.S. dollar and the Colombian peso will behave in the medium to long-term. Given that markets are dealing with a great deal of uncertainty, it is expected that U.S. dollar movements will remain difficult to forecast.

 

A future depreciation in the exchange rate of the Colombian Peso against the U.S. dollar may affect our financial results when converted into Colombian Pesos, given the portion of our U.S. dollar debt that is not designated as hedge instrument and the future debt we may acquire. Please see our sensitivity analysis on our results of operation to exchange rate fluctuations in the section Financial Review—Effect of Taxes, Exchange Rate Variation, Inflation and the Price of Oil on our Results—Exchange Rate Variation and in Note 30.2 to our consolidated financial statements.

 

Increased competition from local and foreign oil companies may have a negative impact on our ability to gain access to additional crude oil and natural gas reserves in Colombia and abroad.

 

We must bid for exploration blocks offered by the ANH in Colombia and similar authorities in other countries, which means we compete under the same conditions as other domestic and foreign oil and gas companies, and receive no special treatment. Our ability to obtain access to potential fields also depends on our ability for evaluating and selecting potential opportunities and to adequately bid for such opportunities.

 

We are also exposed to international competition as a result of our international exploratory activities. Currently, we are exploring in Brazil, Mexico and the US Gulf of Mexico, where we both partner and compete with other oil and gas companies operating in those locations.

 

If we are unable to adequately compete with local and foreign oil companies, or if we cannot enter into joint ventures with market players having high potential exploration projects, our exploration activities may be limited. This could reduce our market share and, in turn, adversely affect our financial condition.

 

  96  

 

 

If operational risks to which we are exposed in Colombia or overseas materialize, the health and safety of our workforce, the local community and the environment may be affected. In addition, we may suffer a disruption or shutdown of our operational activities.

 

Our exploration, production, refining and transportation activities in Colombia and in the foreign countries in which we operate are subject to industry-specific operating risks, some of which, despite our internal procedures and adherence to industry best practices, are beyond our control. Our operations may be curtailed, delayed or cancelled due to adverse or abnormal weather conditions, natural disasters, blockages in the communities in which we operate, equipment failures or accidents, oil or natural gas spills or leaks, shortages or delays in the availability or in the delivery of equipment, delays or cancellation of environmental licenses or other government authorizations or judicial decisions, fires, explosions, blow-outs, surface cratering, pipeline failures, theft and damage to our transportation infrastructure, sabotage, terrorist attacks and criminal activities.

 

Some of our operations in Colombia and abroad could be conducted in remote and uninhabited locations which involve health and safety risks that could affect our workforce. By our own Company policy and practices, as well as under Colombian law and international industrial safety regulations, we are required to have health and safety practices that minimize risks and health issues faced by our workforce. Failure to comply with health and safety regulations in the jurisdictions where we operate may lead to investigations by health officials that could result in lawsuits or fines.

 

We may be required to incur in additional costs and expenses to allocate funds to industrial safety and health compliance under Colombian law and international industrial safety regulations. Additionally, if any operational incident occurs that affects local communities and ethnic communities in nearby areas, we will need to incur in additional costs and expenses in order to return affected areas to normality and to compensate for any damages we may cause. These additional costs may have a negative impact on the profitability of the projects we may decide to undertake.

 

The occurrence of any of these operating risks could result in substantial losses or slowdowns to our operations, including injury to our employees, malfunction or destruction of property, equipment and infrastructure, clean-up responsibilities, third-party liability claims, government investigations and imposition of fines, withdrawal of environmental licenses and other government permits, suspension or shutdown of our activities and loss of revenue. The occurrence of any of these events may have a material adverse effect on our financial condition and results of operations.

 

Our involvement in deep-water drilling either as direct operator or in conjunction with our business partners involves risks and costs, which may be out of our control.

 

Our deep-water drilling activities present severe risks, such as the risk of spills, explosions on platforms and drilling operations, and natural disasters. The occurrence of any of these events or other incidents could result in personal injuries, loss of life, severe environmental damage with the resulting containment, clean-up and repair expenses, equipment damage and liability in civil and administrative proceedings. Heightened risks and costs associated with deep-water drilling may have a negative effect on our results of operations and financial condition and in our reputation.

 

See the section Business Overview—Exploration and Production—Exploration Activities—Exploration Activities Outside of Colombia for a summary of our current deep-water drilling activities.

 

As a result of the oil spill in the Macondo field operated by British Petroleum in the U.S. Gulf Coast in April 2010, significant concerns regarding the safety of deep-water drilling have been raised and, as a result, applicable regulations in various countries have changed. More stringent government regulation may result in increased costs and longer exploration and development timeframes for our deep-water drilling operations and consequently could adversely affect our results of operations and financial condition.

 

We are exposed to the credit, political and regulatory risks of our customers and any material nonpayment or nonperformance by our key customers could adversely affect our cash flow and results of operations.

 

Some of our customers may experience financial problems that could have a significant negative effect on their creditworthiness. Severe financial problems encountered by our customers could limit our ability to collect amounts owed to us, or to enforce the performance of obligations owed to us under contractual arrangements. In addition, many of our customers finance their activities through their cash flows from operations, short and long term debt or equity.

 

  97  

 

 

The combination of decreasing cash flows as a result of declines in commodity prices, a reduction in borrowing bases under reserve-based credit facilities and the lack of availability of debt or equity may result in a significant reduction of our customers’ liquidity and limit their ability to make payments or perform their obligations to us according to their contractual terms.

 

Furthermore, some of our customers may be highly leveraged and subject to their own operating expenses. Therefore, the risk we face in doing business with these customers may increase. Other customers may also be subject to regulatory changes, which could increase the risk of defaulting on their obligations to us. Financial problems experienced by our customers could result in the impairment of our assets, a decrease in our operating cash flows and may also reduce or restrict our customers’ future use of our products and services, which may have an adverse effect on our revenues.

 

Our ability to access the credit and capital markets on favorable terms to obtain funding to refinance our debt maturities may be limited due to the deterioration of these markets, any change to our credit ratings and the authorizations we need before incurring any financial indebtedness.

 

A new financial crisis, volatility in prices in the oil and gas sector, the spread in protectionist policies in the United States and Europe, the lack of consensus among OPEC members, the discovery of corruption by governments and private companies in emerging markets and further geopolitical disruptions in the Middle East, which could involve developed countries, which in turn could worsen risk perception with respect to the emerging markets, or the occurrence of any of the risks described in the section Risk Review—Risk Factors—Risks Related to Colombia’s Political and Regional Environment could make it more difficult for us and our subsidiaries to access international and local capital markets and finance our operations and potentially refinance our debt maturities on terms acceptable to us. These conditions, along with significant write-offs in the financial services sector and the re-pricing of credit risk, can make it difficult for us to obtain funding for our capital needs on favorable terms. Access to credit and capital markets is also dependent on our credit ratings, which are mainly determined by our financial and operational strength, oil and gas market conditions and the support that could be provided by the Colombian government. We cannot assure that our credit ratings will continue for any given period of time or that the ratings will not be further lowered or withdrawn. An assigned rating may be raised or lowered depending, among other things, on the respective rating agency’s assessment of our financial strength. In addition, a downgrade in the rating of the Republic of Colombia could also trigger a downgrade on our ratings as our rating is capped by the rating of the Republic of Colombia and the implicit support that can potentially be provided to the Company. On March 14, 2017, Fitch Ratings maintained our long term international credit rating at BBB but upgraded our outlook from negative to stable following the upgrade from the Republic of Colombia from negative to stable also in March 2017. On June 27, 2017, S&P increased our stand-alone credit rating from BB to BB+ and maintained our long-term international credit rating at BBB and our outlook as negative, in line with those of the Republic of Colombia. On December 11, 2017, in line with a downgrade of the Republic of Colombia, S&P lowered our long-term international credit rating from BBB to BBB- and changed our outlook from negative to stable. S&P maintained, however, our stand-alone credit rating at BB+. On September 21, 2017, Moody’s maintained our long term international credit rating at Baa3 and revised our outlook from negative to stable. On February 22, 2018, despite the downgrade of Republic of Colombia, Moody’s maintained our long term international credit rating and outlook. We cannot offer any assurance that our credit rating will continue.

 

As a result of these factors, we may be forced to revise the timing and scope of our capital projects as necessary to adapt to existing market and economic conditions, downgrades to our credit ratings or to access the financial markets on terms less favorable, therefore negatively affecting our results of operations and financial condition.

 

In addition, under applicable regulation, the Government, through the Ministry of Finance and Public Credit and the favorable opinion of the National Planning Department, must authorize all indebtedness of state-owned entities and government-controlled companies through a majority equity stake. Consequently, excluding our foreign subsidiaries or those subsidiaries in which we hold minority interest, most of our indebtedness must be previously authorized by the Colombian Ministry of Finance and Public Credit and the National Planning Department. As such, our indebtedness is subject to the Government’s time frames and policies, and we cannot guarantee that such authorizations would be granted in a timely fashion or granted at all.

 

  98  

 

 

We may be exposed to increases in interest rates, thereby increasing our financial costs.

 

We may incur debt locally and in the international capital markets and, consequently, may be affected by changes in prevailing interest rates. If market interest rates increase, our financing expenses may increase, which could have an adverse effect on our results of operations and financial condition.

 

As of December 31, 2017, approximately 19%, or US$2.8 billion (COP$8.3 trillion), of our total indebtedness consisted of floating rate debt. If market interest rates rise, our financing expenses will increase, which could have an adverse effect on our results of operations and financial condition. In addition, as we refinance our existing debt in the coming years, the mix of our indebtedness may change, specifically as it relates to the ratio of fixed to floating interest rates, the ratio of short-term to long-term debt, and the currencies in which our debt is denominated in or indexed to. We cannot assure you that such changes will not result in increased financing expenses borne by us. Finally, as we incur new debt in the future to fund our capital projects or inorganic acquisitions, the prevailing interest rates and spreads at any specific time could be less favorable in terms of cost when compared to our previous financing transactions, which could adversely affect our financial condition and results of operations.

 

Our current and planned investments and exploration activities outside Colombia are exposed to political and economic risks.

 

As part of our strategic plan, we operate through business partners, subsidiaries or affiliates outside of Colombia. We currently have investments, joint ventures and subsidiaries incorporated in Peru, Brazil, Mexico, Bermuda, Panama, the Cayman Islands, Switzerland, Germany, Spain, the United Kingdom and the United States, and we are analyzing investments in other countries. In connection with making investments, we are and will be subject to risks related to economic and political conditions and governmental economic actions. We cannot predict the positions of foreign governments relating to the oil and gas industry, land tenure, protection of private property, environmental standards, regulation or taxation; nor can we assure you that future governments will maintain policies favorable to foreign investment or repatriation of capital.

 

We began exploration activities outside Colombia in 2006 through our Brazilian subsidiary, Ecopetrol Óleo e Gás do Brasil Ltda. Our foreign subsidiaries have subsequently entered into a number of joint venture exploration agreements with regional and international oil companies to explore acreage in Brazil and the U.S. Gulf Coast. We have limited experience exploring outside Colombia. We may face new and unexpected risks involving environmental and other legal requirements beyond those we currently experience.

 

The results of operations and financial condition of our subsidiaries in these countries also may be adversely affected not only by risks associated with hydrocarbon exploration and production, but also by fluctuations in their local economies, political instability and government actions, including: the imposition of price controls, the imposition of restrictions on hydrocarbon exports, fluctuation of local currencies against the Colombian Peso, the nationalization of oil and gas reserves, increases in export and income tax rates for crude oil and oil products, and unilateral (governmental) institutional and contractual changes, including controls on investments and limitations on new projects.

 

Any of these conditions occurring could disrupt or terminate our operations, causing our development activities to be curtailed or terminated in these areas, or our production to decline; limit our ability to pursue new opportunities; affect the recoverability of our assets; or cause us to incur additional costs or delay the timeline of our projects.

 

Our future performance depends on the successful development and deployment of new technologies and the knowledge to apply and improve them.

 

Technology, knowledge and innovation are essential to our business, especially for reductions to our operating costs and improvements in processes related to the production and transportation of heavy crude oil and the exploitation of mature fields. If we do not develop the right technology, do not secure access to required third-party technology, fail to deploy the right technology, do not obtain the expertise to operate our deployed technology or to improve our processes, or do not deploy the knowledge necessary to improve such technology effectively, the execution of our corporate goals, our profitability and our earnings may be adversely affected. In the case of our recovery program, we not only depend on the successful selection, adaptation, demonstration and deployment of appropriate technologies but also in the response of the reservoir to the application of these recovery technologies.

 

  99  

 

 

Our performance could be negatively affected by a deficiency in leadership capacity and lack of key skilled employees.

 

As the oil and gas industry faces an increasing number of challenges, the ability to react quickly to these challenges has become a key factor in achieving efficiency, profitability, growth and sustainability. Our ability to achieve these goals can be negatively affected by a deficiency in leadership capacity and a lack of key skilled employees that can execute our business strategy with creativity and determination.

 

Our operations may not be able to keep pace with the increasing domestic demand for natural gas.

 

According to the Colombian Energy and Gas Regulatory Commission (CREG) Resolution 114 of 2017, former Resolution 089 of 2013, the natural gas market is a physical market, which means that suppliers must comply with the quantities agreed in their contracts. Hence, Ecopetrol will not be able to keep or increase its market participation unless the Company increases its natural gas reserves as local demand grows.

 

Additionally, we are currently party to a number of national gas supply contracts that have firm gas commitments. If we are unable to deliver natural gas to these clients as a result of cuts in operations, delays in the completion of projects relating to our production facilities or the acceleration of the decline in our gas production, among other reasons, we may be required to compensate our customers for our failure to supply natural gas.

 

Delays in the start of new projects could result in penalties imposed on us by our clients. Although we did not pay penalties due to delays in the start of new projects in 2017, we cannot assure you that in the future we will not be subject to additional monetary fines which can in turn affect our financial condition and results of operations.

 

We depend on others for the construction and availability of natural gas transportation infrastructure for the transport of our gas, which may limit our ability to develop new or existing fields or lead to the deterioration of related assets and may not allow us to recover the cost of capital invested in natural gas discoveries.

 

Ecopetrol S.A. can only hold up to 25% of the equity of any natural gas transportation company. Therefore, there can be no assurance that the transportation infrastructure necessary to transport natural gas from the fields to distribution points and our customers will be built by third parties or that if built there will be sufficient capacity available to us for the exploitation of new natural gas discoveries or the development of existing fields. The failure to commercially exploit new or existing discoveries may result in impairment of the related assets and our inability to recover the capital expenditures invested to make these natural gas discoveries. As a result, we may be required to enter into agreements with natural gas transportation companies on terms that are not favorable to us.

 

For example, we have developed natural gas reserves in the Cusiana and Cupiagua fields, but transportation capacity to deliver gas from these fields is currently limited. Although there are projects under development that will eliminate this limitation in 2018, we can offer no assurance that they prove successful.

 

Our operations could be affected by reactions of labor unions, social organizations and contractors to Colombia’s political and social environment, organizational changes and the collective bargaining agreement negotiation process.

 

Due to Colombia’s political and social environment and organizational changes, social organizations in the communities where we have operations, contractors and unions, may have reactions and present their demands through social movements, which could have an adverse effect on our operations and financial condition.

 

  100  

 

 

In addition, our current collective bargaining agreement has been in effect since 2014 and has a term of four years, expiring June 30, 2018. There will be no changes to these terms until June 2018 or until the end of the negotiation process. If the unions do not present any request of negotiation, the terms will be maintained for another six months. During this period of time, the collective bargaining agreement negotiation will take place and unions may try to impact our normal operations. Further, we cannot assure you will not experience strikes or labor unrest in the future.

 

Our activities may be interrupted or affected by external factors, such as abnormal weather conditions and natural disasters.

 

We are exposed to several risks that may partially interrupt our activities. They include fires or explosions, natural disasters, criminal acts and acts of terror, malfunction of pipelines and emission of toxic substances.

 

Also, the effects of climate change could create impacts and losses in any part of our business operations, for instance, as the result of increase in the intensity of the “La Niña” and “El Niño” climate phenomena, causing floods and drought periods, increased temperature and rising sea levels.

 

The “El Niño” climate phenomenon is characterized by (i) a lack of rainfall, which limits the amount of water necessary for the development of various activities of the company, and (ii) increased temperatures, which could have a direct impact on our worker’s health given an increased occurrence of heat waves and the increased occurrence of epidemics and diseases. The “La Niña” climate phenomenon is characterized by increased rainfall, which can generate (i) landslides that threaten pipeline infrastructure and limit road transportation and (ii) flooding, which could limit operations in our production fields and facilities.

 

As a result, our activities could be significantly affected or even paralyzed. These risks could result in property damage, loss of revenue, loss of life, pollution and harm to the environment, among others. If any of these occur, we may be exposed to economic sanctions, damages, fines or penalties in addition to the costs required to repair or remediate the related damage. These costs, fines and penalties may adversely affect our financial condition and results of operations.

 

Our operations, including our activities in areas classified as indigenous reserves and Afro-Colombian lands, are subject to opposition from members of various communities.

 

We currently carry out and plan to continue carrying out activities in areas classified by the Government as indigenous reserves and Afro-Colombian lands. In order to undertake these activities, we must first comply with the previous consultation process, set forth by Colombian law. These consultation processes are part of the administrative procedures for obtaining environmental licenses to start our projects, works or activities in areas belonging to ethnic communities. In addition, consultations can be seen as a potential instrument to involve communities in the decision of developing extracting industry and infrastructure projects in their territories. Generally, these consultation processes last between six months to one year depending on the community expectations, but may be significantly delayed if we cannot reach an agreement with the communities. We strive to be respectful of the Constitution and laws and the autonomy of indigenous and Afro-descendant communities, and we therefore do not enter their territories until we have reached an agreement with them.

 

Our activities are subject to opposition, including protests by various communities, and even in areas in which the previous consultation process does not apply. Recently, through popular consultation, some communities have voted against the development of extractive industry projects. Any such similar situation may affect our future projects.

 

In recent years, indigenous communities have been claiming their ancestral territories and requesting recognition on previously closed consultation processes. We may be exposed to operational restrictions as a result of the opposition of these communities.

 

  101  

 

 

No certainty can be given that we will be able to reach an agreement with the different communities opposed to our operations or that such communities will participate in consultation processes if available. We may be exposed to similar delays due to opposition from local communities in other countries where we carry out our activities.

 

We have made significant investments in acquisitions and we may not realize the expected value.

 

We have acquired interests in several companies in Colombia and abroad. See the section Business Overview—Our Corporate Structure . Obtaining the expected benefits of the acquisitions will depend, in part, on our ability to (i) obtain the expected results of operations and financial condition from these acquisitions, (ii) manage disparate operations and integrate distinct corporate cultures, (iii) manage our objectives as a corporate group, and (iv) institute our corporate governance rules as well as other factors beyond our control such as the economic and regulatory environment in countries in which we have made acquisitions and crude oil prices. These efforts may not succeed. Our failure to successfully obtain the expected results from our acquisitions could adversely affect our financial condition and results of operations.

 

We might be required to provide additional financial support to Bioenergy despite its recent completion.

 

Bioenergy’s ethanol plant, which began operations in April 2017 was financed with COP$132 billion through bilateral loans for its agricultural component and COP$382 billion through an infrastructure leasing for its industrial component. Although Ecopetrol is not the sponsor and has not provided financing guarantees to Bioenergy, some additional financial support might be needed to assure the stabilization phase of the plant. Additionally, Bioenergy may also face situations such as social unrest, strikes or other operational difficulties that could negatively impact its operation and financial results.

 

Any situation that could affect the operations of this subsidiary may have a negative impact on its profitability as well as on its ability to pay its debt, which in turn could adversely affect our financial condition and results of operations.

 

Ongoing Colombian State control entities investigations regarding our subsidiaries Reficar and Bioenergy could adversely affect us.

 

Ecopetrol, Bioenergy and Reficar’s employees are generally subject to the control and supervision of the Colombian State control entities. See section Risk Review—Legal Proceedings and Related Matters for additional information.

 

The investigations concerning Reficar and Bioenergy that are described in section Risk Review—Legal Proceedings and Related Matters remain ongoing. While we are cooperating fully with both cases, adverse developments in connection with these investigations, including any expansion of the scope of the investigations, could negatively impact us and could divert the efforts and attention of our management team from our ordinary business operations.

 

In connection with this investigation or any other investigation carried out by any other authority, there can be no assurance that we will not incur in additional costs and expenses or expose us or our employees to sanctions and lawsuits, any of which could adversely impact our reputation and, in turn, could have adverse effects on our financial condition and results of operations. See section Risk Review—Legal and Regulatory Risk—We may incur losses and spend time and money defending pending lawsuits and arbitrations and responding to administrative investigations .

 

Our results may be affected by the performance of our business partners or their third-party service providers, as many of our operations are executed under joint venture agreements.

 

Many of our operations are performed through joint ventures with our business partners. Consequently, we depend on the performance of our business partners. The poor performance of any of them, especially in those projects in which we do not act as operator, could negatively impact oil and natural gas production, which in turn could have a negative impact on our results of operations and financial condition. We are exposed to the risk of not finding business partners with the appropriate skills and performance we require for our projects. We are also indirectly exposed to supply agreements and other third-party services contracted by our business partners acting as operators under joint venture agreements.

 

  102  

 

 

Our insurance policies do not cover all liabilities and may not be available for all risks.

 

Our insurance policies do not cover all liabilities, and insurance may not be available for all risks. There can be no assurance that incidents will not occur in the future, that insurance will adequately cover the entire scope or extent of our losses or that we will not be found liable in connection with claims arising from these and other events, which could adversely affect our financial condition and results of operations.

 

A failure in our information technology systems or cyber security attacks may adversely affect our financial results.

 

We depend on the reliability and security of our information technology systems to conduct certain exploration, development and production activities, process financial records and operating data, communication with our employees and business partners, and for many other activities related to our business. Our information technology systems may fail or have other significant shortcomings due to operational system flaws or employee misuse, tampering or manipulation. In addition, we may become the target of cyber-attacks or information security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of proprietary and other information. Any of these occurrences could disrupt our business, result in potential liability or reputational damage or otherwise have an adverse effect on our financial results.

 

During 2017, our internal cyber security systems identified several cyber security attacks such as brute force login attacks designed to identify valid credentials in IT infrastructure and one ransomware attack with data loss (low level confidentiality) at Ecopetrol S.A. Our platforms also identified and controlled certain malware events and SQL injection attacks.

 

Although we have not experienced any material losses relating to failure of our information technology systems or cyber incidents, there can be no assurance that we will not suffer such losses in the future.

 

We are exposed to behaviors incompatible with our ethics and compliance standards.

 

Given the large number of contracts that we are a party to in Colombia and abroad with local and foreign suppliers, the geographic distribution of our operations and the great variety of actors that we interact within the course of business, we are subject to the risk that our employees, contractors, or any person having relations with us may misappropriate our assets, manipulate our assets or information or engage in money laundering or the financing of terrorism, for such person’s personal or business advantage. Our systems for identifying and monitoring these risks may not be effective to fully mitigate them in all situations. Such acts may result in material financial losses or reputational harm to the Company.

 

The reliability and capacity of national power supply systems may affect or limit the continuity of our operations or limit growth.

 

Our average energy consumption in 2017 was 6,392 GWh/year, of which 72% was supplied through self-generation, and the remaining 28% through power grid. Our demand is 9% of the total energy demand in Colombia.

 

Several producing fields are connected to the national transmission system and depend on its expansion and reliability to keep steady production levels and to accommodate future growth. The national electricity market is volatile due to changes in hydrology and availability of fuels (natural gas, diesel etc.), bringing uncertainty to prices. Ecopetrol centralizes the management of power sources and uses, quality and cost in the short, medium and long term with the objective of optimizing energy consumption, but we cannot offer any assurance that the program will prove successful.

 

  103  

 

 

Rising water production levels may affect or constrain our crude oil production.

 

During 2017, Ecopetrol S.A. produced approximately 9.3 million barrels of water per day. Taking into account the nature of our reservoirs, the water production levels to be managed by the Company may increase in the future. In order to achieve our oil and gas production goals and to avoid any production restrictions going forward, we will need to secure the required capacity to manage water levels. Factors that may trigger a possible constraint in our crude oil production due to the rising water production levels are: (i) ineffective project management of the required facilities, (ii) the Company’s and its partners’ ability to timely obtain the environmental permits related to water management, (iii) social and community interactions that could affect the development and operation of these projects, and (iv) the availability of capital to execute the required projects.

 

5.1.2        Risks Related to Colombia’s Political and Regional Environment

 

This section discusses potential risks related to our extensive operations in Colombia.

 

The Colombian government could seize or expropriate Ecopetrol’s assets under certain circumstances for fair compensation.

 

Pursuant to Articles 58 and 59 of the Colombian constitution, the Government can exercise its eminent domain powers in respect of private property assets in the event such action is deemed by the Government to be required in order to protect public interests. According to Law 388 of 1997, eminent domain powers may be exercised through: (i) an ordinary expropriation proceeding, or (ii) an administrative expropriation. In all cases we would be entitled to a fair compensation for the expropriated assets. Also, as a general rule, compensation must be paid before the asset is effectively expropriated. However, the compensation may be lower than the price for which the expropriated asset could be sold in a free-market sale or the value of the asset as part of an ongoing business. The aforementioned Article 59 of the Colombian constitution establishes an expropriation for war reasons, which require that compensation be paid before expropriation but can only be executed on a temporary basis.

 

Colombia has experienced internal security issues that have had or could have a negative effect on the Colombian economy and on us.

 

Colombia has experienced internal security issues, primarily due to the activities of guerrillas, paramilitary groups, drug cartels and criminal bands known as Bacrim . From time to time, guerrillas target crude oil and multi-purpose pipelines, including the Oleoducto Transandino, Caño Limón-Coveñas and Oleoducto Bicentenario pipelines, and other related infrastructure disrupting our activities and those of our business partners.

 

During 2017, the attacks against our pipeline infrastructure increased by 28% in relation to 2016 (49 attacks in 2016 compared with 63 attacks in 2017). This situation especially affected the infrastructure located in the following departments: Norte de Santander, Arauca and Nariño and the following pipelines: Caño Limón Coveñas and Transandino. One of the consequences of the 2017 attacks is a deferred production of 1.6 million barrels. On several occasions, guerilla attacks have resulted in unscheduled shutdowns of our transportation systems in order to repair or replace sections of pipelines or production facilities that have been damaged with deferral of production in certain fields, as well as caused us to undertake environmental remediation. For the pipeline infrastructure managed by Ecopetrol S.A, the direct cost of repairs due to terrorist attacks in 2017 was approximately COP$20,313 million (US$6.8 million, with a COP$2,984/1.00 US exchange rate as of December 31, 2017). During the first four months of 2018, there have been 33 attacks against the infrastructure of the Caño Limón Coveñas and Transandino pipelines. So far, however, these attacks have not resulted in deferred production due to the transportation of the crude from the Caño Limón field through the Bicentenario pipeline from Banadia in Arauca to Araguany in Casanare. We cannot offer any assurance that we will continue to ensure such transportation through alternate routes.

 

Likewise, the theft of refined products and crude oil, resulting from security issues, may impact our operating and financial results in the future. Theft of refined products, increased from approximately 28.5 boed in 2016 to approximately 34.9 boed in 2017. Theft of crude oil increased from approximately 1,796 bod in 2016 to approximately 1,883 bod in 2017.

 

  104  

 

 

These activities and their possible escalation and the effects associated with them have had, and may have in the future, a negative impact on the Colombian economy or on us, which may affect our customers, employees, assets or the environment, with resulting containment, clean-up and repair expenses.

 

Despite the peace agreement between the Colombian government and the FARC and the ongoing peace negotiation process with the National Liberation Army (the ELN), some illegal and terrorist activities of guerrilla groups or their members may continue

 

On November 30, 2016, the Colombian Congress approved a peace agreement between the Colombian government and the Revolutionary Armed Forces of Colombia, or FARC. Currently, the Colombian government is in the process of gradually integrating FARC members into civilian life.

 

On the other hand, the National Liberation Army, or ELN, an insurgency guerrilla group, has increased its actions against the Colombian security forces and the critical infrastructure of the Nation in recent months, which we believe is an attempt to show its presence and influence in some regions and put pressure on the ongoing peace negotiations which formally began in February 2016. In February 2017, the public dialogue phase began in Quito, Ecuador. These dialogues were interrupted as a result of the terrorist attacks carried out by the ELN since January 9, 2018, when the bilateral ceasefire ended. The Colombian Government decided to resume the dialogue in April 2018, due to the suspension of ELN terrorist actions during the electoral period in March 2018. It is expected that attacks against critical infrastructure will continue until a new bilateral ceasefire can be agreed upon.

 

Despite the progress made with the FARC and the now stalled negotiations with the ELN, some guerrilla groups may continue their illegal and terrorist activities, resulting in a deterioration of Colombia’s national security and consequently may negatively impact our operating results.

 

There have been certain events in Colombia and abroad, which have resulted in political tensions between Colombia and some of its neighboring countries.

 

There have been certain events in Colombia and abroad, which have resulted in political tensions between Colombia and some of its neighboring countries.

 

Economic differences between Colombia and Venezuela, mainly due to Venezuela’s current public order situation and internal political tension, could affect our diplomatic relations, impact border towns and cities and therefore have a negative impact on Colombia’s economy and general security situation.

 

Companies operating in Colombia, including us, are subject to the prevailing economic conditions and the investment climate in Colombia, which may be less stable than the prevailing economic conditions and investment climate in developed countries.

 

Market prices of securities issued by Colombian companies, including us, are subject to the prevailing economic conditions in Colombia. A large portion of our assets and operations are located in Colombia and most of our sales are currently derived from our crude oil and natural gas production and the production of our refineries located in Colombia. Accordingly, our financial condition and results of operations depend to a significant extent on macroeconomic and political conditions prevailing from time to time in Colombia and on the exchange rates between the Colombian Peso and the U.S. dollar.

 

If the perception of improved overall security in Colombia deteriorates or if the investment climate worsens, the Colombian economy may face lower growth rates than the ones posted recently, which could negatively affect our financial condition and results of operations. Furthermore, the market price of our shares and American Depositary Shares, or ADSs, may be adversely affected by changes in governmental policies, particularly those affecting economic growth, exchange rates, interest rates, inflation and taxes. The Government has changed monetary, fiscal, taxation, labor and other policies over time and has thus influenced the performance of the Colombian economy. We have no control over the extent and timing of government intervention and policies.

 

  105  

 

 

Colombian political and economic conditions have a direct impact on our business and may have a material adverse effect on us.

 

Colombia’s economic policies may have direct impact on our Company as well as market conditions, the prices of securities and our ability to access national and international capital markets. Our financial condition and results of operations may be adversely affected by the following factors, among others, and the Government’s response to such factors: exchange rate movements; inflation; exchange control policies; price instability; interest rates; liquidity of domestic capital and lending markets; tax policy; regulatory policy for the oil and gas industry, including pricing policy; and other political, diplomatic, social and economic developments in or affecting Colombia.

 

Uncertainty over whether the Government will implement changes in policy or regulations that may affect any of the factors mentioned above or other factors in the future may lead to economic uncertainty in Colombia and increase the volatility of the Colombian securities market and securities issued abroad by Colombian companies. The upcoming 2018 Colombian presidential election could also result in changes to policies that may have an adverse effect on the local market and consumer confidence that may impact our business and have a material adverse effect on us.

 

Developments and the perception of risk in other countries, especially emerging market countries, may adversely affect the market price of Colombian securities, including our ADSs.

 

Securities issued by Colombian companies may be affected by economic and market conditions in other countries, including other Latin American and emerging market countries. Although economic conditions in Latin American countries and in other emerging market countries may differ significantly from economic conditions in Colombia, investors’ reactions to developments in these other countries may have an adverse effect on the market value of securities of Colombian issuers and our ability to access capital markets.

 

Due to past financial crises in several emerging market countries (such as the Asian financial crisis of 1997, the Russian financial crisis of 1998 and the Argentine financial crisis of 2001), the world financial crisis of 2008 and the recent sovereign debt crises in certain European countries, investors may view investments in emerging markets with heightened caution. In the past, as a result of crises in other countries, flows of investments into Colombia have been reduced. Crises in other countries, especially in emerging market countries, may hamper investor enthusiasm for securities of Colombian issuers. If Latin America experiences a new slow-down or if the price for securities of Latin American issuers falls, the price for our ADSs could follow this trend and could be adversely affected as could our ability to access domestic or international capital markets.

 

New or higher taxes resulting from changes in tax regulations or the interpretation thereof in Colombia could adversely affect our results of operations and financial condition.

 

New tax laws and regulations, and uncertainties in the interpretation with respect to existing and future tax policies pose risks to us. In recent years, the Colombian Congress and tax authorities have imposed and subsequently eliminated additional taxes such as the Income Tax for Equality (“CREE”) and the wealth tax, and enacted modifications to taxes related to financial transactions, income, value added tax (“VAT”), and taxes on net worth. In addition, in December 2016, pursuant to Law 1819, the Colombian Congress enacted a tax reform, which became effective in 2017. For a description of taxes affecting our results of operations and financial condition in 2017, see section Financial Review Effect of Taxes, Exchange Rate Variation, Inflation and the Price of Oil on Our Results Taxes . Changes in tax-related laws and regulations, and interpretations thereof, can affect tax burdens by increasing tax rates and fees, creating new taxes, limiting tax deductions, and eliminating tax-based incentives and non-taxed income. In addition, tax authorities and tax courts may interpret tax regulations differently than we do, which could result in tax litigation and associated costs and penalties.

 

  106  

 

 

Until recently, for Colombian income tax purposes, dividends that were distributed from profits taxed at the corporate level were not taxed or subject to withholding tax at the shareholder level. However, beginning in 2017, dividends paid to non-resident shareholders are subject to a withholding tax. The withholding tax rates applicable to dividends paid to non-resident shareholders are: (i) a 5% dividend tax on dividends distributed from profits taxed at the corporate level; and (ii) a 35% withholding tax rate on dividends distributed from profits not taxed at the corporate level plus an additional 5% dividend tax after applying the initial 35% withholding tax rate. Tax treaty rules might also apply on dividend distributions when a shareholder is a resident in a country that has executed a tax treaty with Colombia.

 

5.1.3        Legal and Regulatory Risks

 

This section discusses potential legal and regulatory risks to Ecopetrol, including the risk of having to comply with new laws and regulations.

 

Our operations are subject to extensive regulation.

 

The Colombian hydrocarbons industry is subject to extensive regulation and supervision by the Government and regulatory agencies in matters including the award of exploration and production blocks by the ANH, the imposition of specific drilling and exploration obligations, restrictions on production, price controls, capital expenditures, liquidation of the Net Position of each refiner or importer with respect to the FEPC and required divestments. Existing regulation applies to virtually all aspects of our operations in Colombia and abroad. The commercialization activities of some of our products also face extensive regulation. Such regulation is subject to change by the applicable regulator affecting our ability to commercialize our products. See section Business Overview—Applicable Laws and Regulations .

 

The terms and conditions of the agreements with the ANH under which we explore and produce crude oil and natural gas generally reflect negotiations with the ANH and other governmental authorities and may vary by fields, basins and hydrocarbons discovered.

 

We are required, as are all oil companies undertaking exploratory and production activities in Colombia, to pay a percentage of our production to the Government as royalties. The Colombian Congress has modified the royalty program for crude oil and natural gas production several times in the last 20 years, as it has modified the regime regulating new contracts entered into with the Government. In the future, the Colombian Congress may once again amend royalty payment levels for new contracts and such changes could have an adverse effect on our future exploration and production in Colombia. See section Business Overview—Applicable Laws and Regulations—Regulation of Exploration and Production Activities—Business Regulation—Royalties for a description of the current royalty scheme.

 

Our operations in Colombia are subject to extensive national, state and local environmental regulations. Environmental rules and regulations are applicable to our exploration, production, refining, transportation, supply and marketing activities, as well as the biofuels we produce. These regulations establish, among other things, quality standards for hydrocarbon products, air emissions and greenhouse gases, water discharges and waste disposal, soil remediation, water pollution and the general storage, handling, transportation and treatment of hydrocarbons in Colombia. Currently, all exploratory projects drilling in areas that do not yet have a license must undergo an environmental impact assessment and must receive an environmental license from the governmental agency responsible for awarding environmental licenses, the Environmental License National Agency or ANLA. Environmental authorities with jurisdiction over our activities routinely inspect our crude oil fields, refineries and other production sites, and they may decide to open investigations or sanction proceedings, which may result in the imposition of fines, restrictions on operations or other sanctions in connection with potential non-compliance with environmental laws.

 

We are also subject to control and monitoring by the regional autonomous corporations (CAR), which are regional environmental authorities that grant permits for the use and exploitation of natural resources, establish compensation measures for the use of these resources, and perform monitoring, control and sanctions function.

 

  107  

 

 

If we fail to comply with any of these national or regional environmental regulations or authorities, we could be subject to administrative and criminal penalties, including warnings, fines or closure orders of our facilities. Any such criminal penalty would be imposed on the legal representatives of the Company, including any legal representative, director or worker who participated or failed to take action related to the activities that lead to environmental damage. See section Business Overview—Applicable Laws and Regulations—Regulation of Exploration and Production Activities—Business Regulation—Environmental Licensing and Prior Consultation .

 

Environmental regulation has become more stringent in Colombia in recent years. As a result, our operating costs have increased in order to comply with these new technical environmental requirements as well as the need to strengthen our specialized team in charge of environmental compliance in project and operations. If environmental laws continue to impose additional costs on us, we may need to reduce our investments on strategic projects in order to allocate funds to environmental compliance. We are also exposed to delays in obtaining environmental licenses from ANLA, which can lead to cost overruns or to changes in our investment plans. These additional costs may have a negative impact on the profitability of the projects we intend to undertake or may make them economically unattractive, in turn having a negative impact on our results of operations and financial condition.

 

Some of the companies in the business group perform exploratory activities outside of Colombian territory. As such, such companies are subject to foreign environmental regulations for the exploratory activities conducted by the business group outside of Colombia. Failure to comply with foreign environmental regulations may result in investigations by foreign regulators, which could lead to fines, warnings or temporary suspensions of our operations, which could have a negative impact in the consolidated financial statements and results of operations of the group.

 

In addition, the companies of the business group conducting upstream activities outside Colombia may be subject to foreign health, safety and environmental regulations. Foreign health and safety regulations may be more severe than those established under Colombian law and, therefore, we may be required to make additional investments to comply with those regulations.

 

Under certain of our credit agreements, we are under an obligation to comply with international environmental standards established by our lenders or by multilateral institutions. Failure to comply with such environmental standards could result in an event of default under the relevant credit agreements that we, or our subsidiaries, have entered into, which would affect our financial condition.

 

We may incur losses and spend time and money defending pending lawsuits and arbitrations and responding to administrative investigations.

 

We are currently a party to several legal proceedings filed against us. We are also subject to labor-related lawsuits filed by current and former employees in connection with pension plans and retirement benefits. For example, as of December 31, 2017, Ecopetrol S.A. was a party to 3,169 legal proceedings relating to civil, administrative, environmental, tax, and labor claims filed against us in courts and arbitration tribunals, of which 396 met the accounting threshold for an accrual provision. Additionally, Ecopetrol S.A.’s subsidiaries were a party to 1,190 legal proceedings relating to civil, administrative, environmental, tax, and labor claims filed against them of which 18 met the accounting threshold for an accrual provision. We allocate substantial amounts of money and time to defend against these claims, in which the claimants often seek substantial sums of money as well as other remedies. See Note 23 to our consolidated financial statements and see section Risk Review—Legal Proceedings and Related Matters . In addition, in accordance with Colombian law, we and our employees are subject to surveillance and investigations by certain administrative control entities in Colombia, which are intended to determine whether public funds have been misused, mismanaged or misappropriated or whether they have been used in compliance with applicable law. Such investigations may divert the attention of management and subject the Company to reputational risk and increase difficulties in retaining talent. See section Risk Review—Legal Proceedings and Related Matters .

5.1.4        Risks Related to Our ADSs

 

This section discusses potential risks associated with an investment in our American Depository Shares (as opposed to our common shares) by investors outside Colombia.

 

Holders of our ADSs may encounter difficulties in protecting their interests.

 

Holders of our ADSs do not have the same voting rights as holders of our common shares. As set forth in the amended and restated deposit agreement, dated December 29, 2017, among Ecopetrol S.A., JP Morgan Chase Bank, N.A., as depositary (the “Depositary”), and all holders from time to time of our American Depositary Receipts (as amended and restated, the “Deposit Agreement”), holders of our ADSs may instruct the Depositary, to vote on shareholder matters prior to a shareholders’ meeting.

 

Colombian law is not clear about the need to request proxies from existing shareholders. Thus, holders of our ADSs may not become aware of some matters in time to instruct the Depositary to vote their shares.

 

The Deposit Agreement provides holders of our ADSs with the right to instruct the Depositary to vote common shares separately. However, holders of our ADRs should be aware that in Colombia, it is uncertain whether a depositary must vote all common shares of a Colombian corporation in an American Depositary Receipt, or ADR, program in the same manner as a single block or may vote them separately. Accordingly, if either the custodian or the Depositary are not able to vote the common shares (including the right to receive common shares in the form of ADRs) deposited under the Deposit Agreement and any other securities, cash or property from time to time held by the Depositary in respect or in lieu of deposited common shares (the “Deposited Securities”) separately, all such Deposited Securities shall be voted based on the majority vote of the voting instructions timely received from holders of ADRs. In the case of such single block voting, all holders of ADRs, including holders of ADRs for which no voting instructions are timely received and holders of ADRs with voting instructions contrary to the voting instructions of a majority of the Deposited Securities timely received, should be aware that the Deposited Securities shall all be voted as a single block and that the voting instructions of such holders of ADRs will be deemed given in the manner stated above.

 

The Depositary will not itself exercise any voting discretion in respect of any Deposited Securities. The holders of our ADRs will be solely responsible for any exercise of the voting rights of the Deposited Securities represented by the ADRs if such vote is made pursuant to the procedures described in the Deposit Agreement. Holders of ADRs are strongly encouraged to forward their voting instructions as soon as possible as voting instructions will not be deemed received until such time as the ADR department responsible for proxies and voting has received such instructions notwithstanding that such instructions may have been physically received by the Depositary, prior to such time.

 

In the future, the Colombian regulatory authorities may clarify their interpretation as to how the voting rights should be exercised by holders of our ADSs, and such possible interpretation could adversely affect the value of the common shares and ADSs.

 

Our ADSs holders may be subject to restrictions on foreign investment in Colombia.

 

Colombia’s International Investment Statute (the set of rules and regulations which govern the foreign exchange market and the transactions thereto, which include Resolution 8 of 2000 and External Circular No. DCIN 83 issued by the Colombian Central Bank among others) regulates the manner in which non-Colombian residents can invest in Colombia and participate in the Colombian securities market. Among other requirements, Colombian law requires foreign investors to register certain foreign exchange transactions with the Colombian Central Bank and outlines the necessary procedures to authorize certain types of foreign investments. Colombian law requires that certain foreign exchange transactions, including international investment in foreign currency between Colombian residents and non-Colombian residents, must be made through authorized foreign exchange market intermediaries. Any income or expenses under our ADR program must be made through the foreign exchange market.

 

Investors acquiring our ADRs are not required to register with the Colombian Central Bank directly, as they will benefit from the registration to be obtained by the custodian for our common shares underlying the ADRs in Colombia. If investors in ADRs choose to surrender their ADRs and withdraw common shares, they must register their investment in the common shares as a portfolio investment through their local representative, which may be a brokerage firm, trust company or investment management companies supervised by the Superintendence of Finance. Investors will only be allowed to transfer dividends abroad after their foreign investment registration procedure with the Colombian Central Bank has been completed. Investors withdrawing common shares could incur expenses and/or suffer delays in the application process. The failure of a non-resident investor to report or register foreign exchange transactions with the Colombian Central Bank relating to investments in Colombia on a timely basis may prevent the investor from remitting dividends abroad, or result in the initiation of an investigation and in the imposition of fines. In the future, the Government, the Colombian Congress or the Colombian Central Bank may amend Colombia’s International Investment Statute or the foreign investment rules, which could result in more restrictive rules and could negatively affect trading of our ADSs.

 

  109  

 

 

Colombia currently has a free convertibility system. If a more restrictive convertibility system is implemented, the Depositary may experience difficulties when converting Colombian Peso amounts into U.S. dollars to remit dividend payments. Also, currently Colombia has a floating exchange rate system that might be subject to change in the future. See section Shareholder Information—Exchange Controls and Limitations .

 

Holders of our ADSs may not be able to effect service of process on us, our directors or executive officers within the United States, which may limit your recovery in any foreign judgment you obtain against us.

 

We are a mixed economy company organized under the laws of Colombia. In addition, most of the members of our Board of Directors (“Directors”) and executive officers reside outside the United States. All or a substantial portion of our assets and the assets of these persons are located outside of the United States. As a result, it may not be possible for you to effect service of process within the United States upon us or these persons or to enforce judgments against us or them in U.S. courts obtained in such courts predicated upon the civil liability provisions of the U.S. federal securities laws. Colombian courts determine whether to enforce a U.S. judgment predicated on the U.S. securities laws through a procedural system known as exequatur . For a description of these limitations, see section Shareholder Information—Enforcement of Civil Liabilities .

 

The protections afforded to minority shareholders in Colombia are different from those in the United States, and may be difficult to enforce.

 

Under Colombian law, the protections afforded to minority shareholders are different from those in the United States. In particular, the legal framework with respect to shareholder disputes is substantially different under Colombian law than U.S. law and there are different procedural requirements for commencing shareholder lawsuits, such as shareholder derivative suits. As a result, it may be more difficult for our minority shareholders to enforce their rights against us or our Directors or controlling shareholder than it would be for shareholders of a U.S. company.

 

ADRs do not have the same tax treatment as other equity investments in Colombia.

 

Although ADRs represent Ecopetrol’s common shares, for Colombian tax purposes, ADRs are securities different from their underlying assets. Therefore, ADR holders are not entitled to the tax treatment granted to holders of the common shares. Such tax treatment includes, among others, those benefits relating to dividends and profits derived from sale of Colombian common shares. For further information see section Shareholder Information—Taxation—Colombian Tax Considerations .

 

Judgments of Colombian courts with respect to our ADSs will be payable only in Colombian Pesos.

 

If proceedings are brought in the courts of Colombia seeking to enforce the rights of ADS holders of common shares, we will be required to discharge our obligation amounts in Colombian Pesos. Colombian law provides that an obligation in Colombia to pay amounts denominated in foreign currency may only be satisfied in Colombian currency at the Representative Market Exchange Rate of the date the judgment is obtained, and such amounts are then adjusted to reflect exchange rate variations through the effective payment date.

 

The relative volatility and illiquidity of the Colombian securities markets may substantially limit our investors’ ability to sell our ADSs at the price and time they desire.

 

Investing in securities that are traded in emerging markets, such as Colombia, often involves greater risk when compared with other world markets, and these investments are generally considered to be more speculative in nature.

 

  110  

 

 

The Colombian securities market is substantially smaller, less liquid, more concentrated and can be more volatile than other securities markets in the United States. As of December 31, 2017, the Colombian Stock Exchange (“BVC”) had a market capitalization of approximately COP$363,843 billion (US$121.93 billion using the closing rate for 2017), a 17% increase when compared with the amount at the end of 2016, a daily average trading volume of approximately COP$138,631 million (US$46.99 million, using the average exchange rate for 2017), a 29% decrease when compared with the volume in 2016. By comparison, the New York Stock Exchange (the “NYSE”) had a market capitalization of US$22.1 trillion as of December 31, 2017, and a daily trading volume of approximately US$32.8 billion in 2017.

 

As of December 31, 2017, our shares represented the highest market capitalization of the BVC accounting for as of 8.9% of the total COLCAP index, which reflects the price volatility of the 20 most-liquid stocks.

 

Given the current ownership structure of our shares, it may be difficult for you to purchase large quantities of shares from a single shareholder. We cannot assure you that a liquid trading market for our ADSs will develop or, if developed, that it will be maintained. Without a liquid trading market, the ability of investors in our ADSs to sell them at the desired price and time could be substantially limited.

 

We are not required to disclose as much information to investors as a U.S. issuer is required to disclose.

 

We are subject to the reporting requirements of the Superintendence of Finance and the BVC - (Colombian Stock Exchange). The corporate disclosure requirements that apply to us may not be equivalent to the disclosure requirements that apply to a U.S. issuer and, as a result, you may receive less interim information about us than you would receive from a U.S. issuer.

 

5.1.5        Risks Related to the Controlling Shareholder

 

Our controlling shareholder’s interests may be different from those of certain minority shareholders.

 

Law 1118 of 2006 requires the Nation to maintain at least 80% of our outstanding capital stock. The Nation currently holds 88.49 % of our outstanding capital stock, making it our controlling shareholder. The Nation as our controlling shareholder has majority voting rights at the General Shareholders Assembly to elect the members of our Board of Directors. The Nation, as controlling shareholder, may propose and approve decisions that are in its own interest and in furtherance of its own economic and political interests that may not necessarily benefit minority shareholders.

 

Our controlling shareholder may approve dividends at the ordinary General Shareholders Assembly, notwithstanding the interest of certain minority shareholders, in an amount that results in us having to reduce our capital expenditures or increase our debt levels, thereby negatively affecting our prospects, results of operations and financial condition. See the section Shareholder Information—Dividend Policy .

 

Additionally, our controlling shareholder may undertake projects, approve decisions or make announcements about its intentions related to its holding of the Company’s stock, which may not be in our best interest or in the best interest of our minority shareholders, including holders of our ADSs, and could affect the price of our shares or ADSs.

 

5.2        Risk Management

 

5.2.1        Managing Risk through Our Internal Control System

 

Under the leadership of the Vice-Presidency of Compliance, Ecopetrol S.A. consolidated its internal control systems into an unified system that integrates the best practices called for by the Committee of Sponsoring Organizations of the Treadway Commission (COSO 2013), Sarbanes–Oxley Act (SOX), governance and management of enterprise IT (COBIT), Enterprise Risk Management (ERM) and our ethics and compliance rules, with the aim of establishing an integrated management system for all control components; thereby allowing us to strengthen all of our control system.

 

  111  

 

 

The main purpose of the Ecopetrol S.A.’s Internal Control System is to provide reasonable assurance regarding the achievement of all of the Company’s objective relating to operations, strategy, reporting and compliance, through the appropriate risks management and ensuring the effectiveness of its controls. The system performance is systematically monitored by the Board of Directors semiannually and by the Audit and Risk Committee monthly.

 

Ecopetrol S.A.’s Internal Control System is aligned to the Company’s strategy and business processes and gives responsibility to all employees to manage risk, to maintain the effectiveness of controls, to report incidents in order to preventively correct possible deficiencies and to provide reasonable assurance of achieving corporate objectives and goals.

 

The risk management component of our Internal Control System is in charge of identifying events or situations that may affect our defined objectives, assessing and prioritizing them to implement the most appropriate response. This component has been designed and implemented across the organization, with a two-level focus: Enterprise Risk and Processes Risks.

 

(i) Enterprise Risks: Are those risks that are directly associated with the business strategy plan of the Company and are systematically monitored by the Management Committee on a monthly basis. The management of those risks is led by a member of the Management Committee; and each risk has a defined treatment plan and monitoring indicators.

 

(ii) Processes Risks: Are those risks that tend to identify potential failures in the activities related to our core and support business processes that drive us to achieve our objectives. At this level, our processes have identified risks with their respective mitigation methods, including financial and non-financial controls, treatment plans and/or monitoring indicators.

 

Our risk management approach is based on the risk management cycle, consisting in five main stages: planning, identifying, evaluating, treatment and monitoring risks, as well as communication across all stages. This cycle is supported in three pillars of risk management: culture, organizational structure and normative and management tools.

 

Three of our most important tools within the risk management component are:

 

(i) Risk Assessment Methodology: In order to properly prioritize mitigation, treatment and monitoring efforts of risk management at the process level, a standardized methodology was established to assess inherent and residual risk levels. The risk level (Very High, High, Medium, Low or None) is obtained from the combination of the consequences (impacts) and the probability of occurrence of those consequences. According with the level of risk, action plans for management and mitigation are defined.

 

(ii) Mitigation Plans: Each year, by performing the stages of the risk management cycle, we define and implement mitigation plans in order to reduce the levels of exposure to risk through mitigation or elimination of some of its causes. Metrics and goals must be defined during the development of each plan to ensure its effectiveness and to prioritize our efforts on those with the greatest impacts.

 

(iii) Monitoring Indicators: As part of the monitoring stage of the risk management cycle, Ecopetrol has implemented Key Risk Indicators (KRIs) which are metrics used to provide early signals of increasing risk exposures. These signals constitute information for preventative decision making in order to avoid risk materialization.

 

Ecopetrol has also defined guidelines to implement an Internal Control System framework for its subsidiaries. Under those guidelines, each subsidiary must report the performance of its Internal Control System to Ecopetrol S.A. to ensure compliance with the above measures, and the subsidiaries have methodological support from Ecopetrol S.A. when requested. Ecopetrol S.A. also performs preventive monitoring in selected subsidiaries to assure all the components and principles of their Internal Control Systems are present and operating.

 

  112  

 

 

5.2.2        Managing Information Security and Cybersecurity

 

Ecopetrol S.A. has a dedicated management team focused on information security issues such as risk analysis, treatment of information, safe information management practices, classification of critical business information, control systems compliance and effectiveness of available information security technologies, all of which are articulated with the ERM system at the enterprise level.

 

Ecopetrol S.A. has included cybersecurity risk as one of the key enterprise risks. Based on that, a working group formed in 2014, coordinated by the information security area with the participation of industrial control systems specialists, has been understanding the new challenges of cybersecurity risk; developing activities to identify and protect critical digital assets.

 

During 2017, Ecopetrol S.A., as a NOC (National Oil Company), provided updates to the Cyber Defense Command Unit (an entity under the control of the Colombian Ministry of Defense) an inventory of its critical cybernetic infrastructure that was included in the classified catalogue of national critical cybernetic infrastructure.

 

Ecopetrol’s cybersecurity team established a plan to continue the incorporation of cybersecurity practices to enhance the awareness about these risks at an operational level and adjust current information security practices considering the new cyberthreat context. Likewise, as a result of this process, we are currently continuing the incorporation of elements relative to management of the cyber security threat, including, policies, specialized monitoring and control mechanisms, vulnerability management, and cybersecurity insurance coverage, among others.

 

Ecopetrol S.A. incorporated a Security Operations Center service, in order to enhance the ability to foresee and identify trends in attacks in Ecopetrol S.A.’s information technology infrastructure and to monitor Ecopetrol’s reputation on the internet.

 

While there were some cyberattacks during 2017, there were no material effects on processes, equipment, products, services, relationships with customers or suppliers, competitive conditions or critical information. Ecopetrol S.A. does not have any current proceedings that relate to cybersecurity issues.

 

Furthermore, during 2017, our internal audit department conducted an audit on cybersecurity processes with an emphasis on the production area. As a result of such audit, an action plan was established to be implemented in 2018. The primary goal of the plan is to reinforce our cybersecurity strategy and refine certain technical components of our cybersecurity program.

 

5.2.3        Managing Financial Risk

 

We are exposed to certain risks associated with the nature of our operations and the financial instruments we use. Among the risks that affect our financial assets, liabilities and expected future cash flows are changes in commodity prices, currency exchange rates, interest rates and the credit quality of our counterparties.

 

Commodity price risk is associated with our day-to-day operations as we export and import crude oil, natural gas and refined products. We occasionally use hedges to partially protect our financial results from price fluctuations taking into account that part of our financial exposure under purchase contracts for crude oil and refined products depends on international oil prices. We believe that the risk of such exposure is partially naturally hedged since we are an integrated group (with operations in the upstream, midstream and downstream segments) and either export crude oil at international market prices or sell refined products at prices that are correlated to international market prices. We do not use derivative financial instruments for speculative or profit-generating purposes.

 

Currency risk arises in our operations given the fact that most of our revenues are derived from sales of products quoted in or with reference to U.S. dollars. Therefore when the Colombian Peso depreciates against the U.S. dollar, our revenues converted into Colombian Pesos, increase. Conversely, when the Colombian Peso appreciates against the U.S. dollar, our revenues decrease. On the other hand, imported goods, oil services and the debt, which is mainly denominated in U.S. dollars, become less expensive when the Colombian Peso appreciates against the U.S. dollar and more expensive when the Colombian Peso depreciates against the U.S. dollar.

 

  113  

 

 

As of December 31, 2017 our U.S. dollar-denominated total debt was US$12.6 billion, which we recognize in our consolidated financial statements at its amortized cost, which corresponds to the present value of cash flows, discounted at the effective interest rate. Out of this total, US$12.0 billion relate to Ecopetrol S.A., whose functional currency is the Colombian Peso. Therefore, when the Colombian Peso depreciates against the U.S. dollar, Ecopetrol S.A. is exposed to an exchange rate loss. In contrast, when the Colombian Peso appreciates against the U.S. dollar, Ecopetrol S.A. is exposed to an exchange rate gain. Some of the Ecopetrol Group’s subsidiaries have the U.S. dollar as functional currency and are not exposed to a material exchange rate risk resulting from fluctuations in the Colombian Peso against the U.S. dollar. On the asset side, when the financial statements of the Group are consolidated, the exchange rate differential of the subsidiaries’ assets and liabilities whose functional currency is the U.S. dollar is recognized directly in equity, as part of other comprehensive income.

 

Taking previous considerations into account, Ecopetrol seeks to identify and manage currency risk in a comprehensive manner, using an integrated analysis of natural hedges in order to benefit from the correlation between income or investments in a foreign operations and debt denominated in foreign currency. In addition, the risk management strategy of the Company may involve the use of financial derivative instruments, and non-derivative financial instruments. As a part of its risk management strategy, using the natural hedge between exports and dollar-denominated debt, on October 1, 2015, US$5.4 billion of Ecopetrol S.A.’s debt in U.S. dollars was designated as hedge instrument of its future export sales for the period 2015 – 2023. On June 8, 2016, Ecopetrol continued its hedge accounting strategy, using the natural hedge between some of its foreign investments and its dollar-denominated debt in an amount of US$5.2 billion. As of December 31, 2017, the outstanding value of the natural accounting hedges was US$8.5 billion. The remaining portion of our dollar-denominated debt, as well as the financial assets and liabilities denominated in foreign currency continue to be exposed to the fluctuation of the exchange rate, which means that an appreciation of the Colombian peso against the U.S. dollar could generate a loss if companies whose functional currency is the Colombian peso have an active net position in U.S. dollars or a gain if they have a net liability position in U.S. dollars. Conversely, a depreciation of the Colombian peso against the U.S. dollar could generate a gain if companies whose functional currency is the Colombian peso have a net active position in U.S. dollars or a loss if they have a net liability position in U.S. dollars. Finally, the Company maintains enough cash in Colombian pesos and U.S. dollars to meet its expenses in each currency (see Note 4.1.5 to our financial statements for further explanation of our accounting policy and Note 30.2 for details of the hedge accounting adopted). With the adoption of hedge accounting, the effect of volatility of foreign exchange rate on the hedged portion of the debt is recognized directly in equity, as part of other comprehensive income. Our hedge management strategy is completely focused on our accounting, reason why the ultimate effect will only be determined when the hedge operations come to an end. Nevertheless, it is important to bear in mind that for Ecopetrol S.A’s cash flow, the effect of the Colombian peso appreciation against the U.S. dollar is positive given the fact that we habitually convert our income in foreign currency to Colombian pesos.

 

Interest rate risk arises from our exposure to changes in interest rates mainly as a result of the issuances of floating rate debt linked to LIBOR, DTF and CPI (with a participation of 5.2%, 8.7% and 3.9%, respectively, of the nominal debt balance as of December 31, 2017). Thus, volatility in interest rates may affect the fair value of and cash flows related to our investments and floating rate debt. In 2017, our analysis of credit risk events and global financial markets drove us to decide not to hedge interest rate risk. Nevertheless, our capital markets office continuously monitors the performance of interest rates and the effect of interest rates on our financial statements.

 

The trust funds linked to Ecopetrol S.A.’s pension obligations (PAP) are also exposed to changes in interest rates, as they include fixed- and floating-rate instruments that are mark to market. This exposure is continuously monitored by our treasury office given the potential impact volatility may have on our financial results. The treasury office’s information is gathered from reports provided by the asset managers. These reports refer to regulatory limits as well as market, credit and liquidity risks. The investment guidelines with respect to the PAPs are issued by the Colombian regulation for pension funds, as stipulated in the Decree 941 of 2002 and Decree 1861 of 2012, where it is indicated that they have to follow the same regime as the regular obligatory pension funds in their moderate (i.e., neither conservative nor aggressive) portfolio. For further information regarding the trust funds linked to the pension obligations of the company, see Note 22.2 Plan assets to our consolidated financial statements.

 

  114  

 

 

Finally, counterparty risk is the potential probability that a borrower or counterparty defaults on any obligation. In our case, we are exposed to this risk as we invest in different financial instruments and receive letters of credit in order to mitigate our exposure with our commercial counterparties. We manage this risk through an analysis of an issuer’s creditworthiness, stock price behavior, spreads on credit default swaps and the probability of default.

 

Investment Guidelines

 

Ecopetrol S.A.

 

Following the promulgation of Decree 1525 of 2008, which provides general rules on investments for public entities, Ecopetrol S.A.’s management established guidelines for our investment portfolios. These guidelines determine that investments in Ecopetrol S.A.’s U.S. dollar portfolio are generally limited to investments of our excess cash in fixed-income securities issued by entities rated A or higher in the long term and A1/P1/F1 or higher in the short term (international scale) by Standard & Poor’s Ratings Services, Moody’s Investors Service or Fitch Ratings. In addition, Ecopetrol S.A. may also invest in securities issued or guaranteed by the U.S. government or Colombian government, without regard to the ratings assigned to such securities. In Ecopetrol S.A.’s Colombian Peso portfolio, it must invest our excess cash in fixed-income securities of issuers rated AAA in the long term, and F1+/BRC1+ in the short term (local scale) by Fitch Ratings Colombia or BRC Standard & Poor’s. In addition, Ecopetrol S.A. may also invest in securities issued or guaranteed by the Colombian government without rating restrictions.

 

In order to diversify risk in our Colombian Peso portfolio, Ecopetrol S.A. does not invest more than 10% of the excess of cash in one specific issuer. In the case of our U.S. dollar portfolio, it does not invest more than 5% of the excess of cash in one specific issuer in the short term (up to one year), or 1% in the long term.

 

Ecopetrol S.A.’s investment portfolio in U.S. dollars is segmented into four tranches, each one matching our liquidity needs. The working capital tranche is calculated taking into account our cash flow needs for the next 60 days. The liquidity tranche is calculated as the contingent cash flow needs over the working capital, taking into account the development of capital expenditures related to projects. The asset liability tranche is built to match our long-term debt. The investment tranche includes the remaining amount of the total portfolio after deducting the amounts pertaining to the above mentioned tranches and after subtracting the Colombian Peso portfolio.

 

Ecopetrol S.A.’s investment portfolio in Colombian Pesos is segmented in two tranches, each one matching our liquidity needs. The first tranche is calculated taking into account our cash flow needs for the next 30 days, and the second tranche is built for investment purposes.

 

5.3        Legal Proceedings and Related Matters

 

We are a party to various legal proceedings in the ordinary course of business. Other than the proceedings disclosed in this annual report, we are not involved in any pending (or, to our knowledge, threatened) litigation or arbitration proceeding that we believe will have a material adverse effect on our Company. Other legal proceedings that are pending against or involve us and our subsidiaries are incidental to the conduct of our and their business. We believe that the ultimate disposition of such other proceedings individually or in an aggregate basis will not have a material adverse effect on our consolidated financial condition or results of operations.

 

As of December 31, 2017, Ecopetrol S.A. was a party to 3,169 legal proceedings relating to civil, administrative, environmental, tax and labor claims filed against us in the Colombian courts and arbitration tribunals, of which 396 had an accrual provision. We allocate sufficient amounts of money and time to defend these claims. Historically, we have been successful in defending lawsuits filed against us. Other than the environmental administrative proceedings described in the last paragraph of this section, based on the advice of our legal advisors, it is reasonable to assume that the litigation procedures brought against us will not materially affect our financial position or solvency regardless of the outcome. See Note 23 to our consolidated financial statements included in this annual report for a discussion of our legal proceedings.

Caño Limón – Coveñas Crude Oil Pipeline Spill

 

On December 11, 2011, the Caño Limón-Coveñas oil pipeline ruptured and caused the spill of approximately 3,267 barrels of crude oil into the Iscala creek, which connects with the Pamplonita River that provides water to the city of Cúcuta. The incident did not cause any fatalities or injuries.

 

A class action lawsuit has been filed against Ecopetrol S.A. and against employees of the company, and the First Administrative Court has jurisdiction to conduct the case, which is in the probatory stage.

 

The Regional Environmental authority of Norte de Santander, or Corporación Autónoma Regional de la Frontera Nororiental (CORPONOR) has filed a lawsuit against Ecopetrol at the Administrative Court of Norte de Santander claiming for (i) the environmental loss caused by the incident and (ii) for compensation costs relating to the environment damage for approximately COP$33 billion. Ecopetrol’s legal counsel filed to dismiss the lawsuit on June 2, 2014, based on three grounds: (i) there is no proof of environmental loss, (ii) CORPONOR does not have the authority to file this lawsuit and (iii) CORPONOR’s petition for direct compensation is not the proper legal action according to the applicable procedural rules. Currently this lawsuit is in probatory stage.

 

Ecopetrol and national and local authorities convened to develop a project consisting of an alternative to the water supply in the intake of the aqueduct in Cúcuta, The Company’s Board of Directors in December 2011 approved the participation of Ecopetrol in the project as part of the strengthening of its contingency plans and its relationship with its stakeholders. On November 10, 2017, the relevant parties entered into an agreement with the purpose of building the alternative water supply at a cost of approximately COP$385 billion. According to the agreement Ecopetrol will be in charge of the construction of the above mentioned infrastructure.

 

BT Energy Challenger

 

On October 22, 2014, we were served with a class action suit against us seeking monetary damages of approximately COP$7.4 trillion related to an incident that occurred on August 21, 2014, during the loading operations of the BT Energy Challenger vessel. The claimants alleged possible damage to the port area of Ecopetrol’s terminal in Coveñas, as well as of marine and submarine areas and beaches that form the geographical area of the Morrosquillo Gulf. This allegation is currently under investigation by the Harbor Master of Coveñas. Ecopetrol filed a motion requesting the judge to require the claimants to amend their claim to more precisely set forth the facts and evidence it believes establishes Ecopetrol’s liability.

 

On March 3, 2015, Ecopetrol filed its statement of defense arguing the exclusive fault of a third party. On October 20, 2015, the Court denied a class action of more than 100 informal traders in the region because there is no common identity with the initial class (hotel employees). However, during 2016 the Sucre Administrative Tribunal accepted another 1208 informal traders and fishermen as claimants.

 

On March 10, 2017, a mandatory conciliatory hearing was held in order to seek an agreement but it failed.

 

In January 2018, a judicial order was issued to commence the evidence gathering process, a decision which was objected by the parties.

 

PetroTiger

 

As highlighted in previous 20-F and 6-K filings, on January 6, 2014, the United States Department of Justice (DOJ) announced the unsealing of charges against two former co-chief executive officers (CEOs) and the former general counsel of PetroTiger Ltd. (PetroTiger), alleging, among other things, violations of the U.S. Foreign Corrupt Practices Act (FCPA) and conspiracy to commit violations of the FCPA and money laundering in connection with payments made to an Ecopetrol employee. By the time of the DOJ announcement, that employee no longer worked at the Company. The DOJ alleged the payments were made to secure Ecopetrol’s approval for PetroTiger’s entry into an oil services contract with Mansarovar Energy Colombia Ltd. Ecopetrol participated in the Mansarovar project as non-operating partner in a joint operating agreement. Also on January 6, 2014, the DOJ announced that the general counsel of PetroTiger had pled guilty on November 8, 2013, to one count of conspiracy to violate the FCPA and to commit wire fraud. One of the charged former co-CEOs pleaded guilty on February 18, 2014, to the same charge. On May 9, 2014, the DOJ charged the other former co-CEO with conspiracy to violate the anti-bribery provisions of the FCPA, conspiracy to commit wire fraud, conspiracy to launder money, and substantive FCPA anti-bribery and money laundering violations. On June 15, 2015, that co-CEO pleaded guilty to conspiracy to violate the FCPA.

 

  116  

 

 

After the DOJ unsealed its charges on January 6, 2014, Ecopetrol filed a complaint the same month, jointly with the Transparency Secretariat of the Presidency of the Republic, to Colombia’s Attorney General’s office requesting the investigation of individuals who may have been involved in the wrongdoing related to the Mansarovar contract. Colombian authorities initiated a proceeding related to PetroTiger, and on March 11, 2015, arrested four current Ecopetrol employees and two former Ecopetrol employees related to their investigation of the Mansarovar project and five other contracts involving PetroTiger and Ecopetrol. To date, four investigations of the control entities continue in course. During 2017 and 2018 to date, Colombian authorities have resolved an appeal confirming the conviction of a former Ecopetrol employee and another person involved in the case but not linked with Ecopetrol. Likewise, another appeal submitted by Ecopetrol and the Prosecutor’s Office is in progress in a case in which a former Ecopetrol employee was acquitted.

 

Ecopetrol has responded to information requests from the DOJ and Colombian authorities in connection with their investigations of PetroTiger. Ecopetrol has been designated with the formal status of victim in the local Colombian proceedings. It has terminated the employment of the four charged individuals who were Ecopetrol employees at the time of the arrests. Ecopetrol has concluded an internal investigation and has not identified any new issues relating to PetroTiger.

 

Salgar-Cartago Multipurpose Pipeline Spill

 

On December 23, 2011 our Salgar-Cartago pipeline ruptured. Internal and external experts believe this incident occurred as a result of creep movement of soil caused by severe weather conditions, causing the soil surrounding the pipeline to exert strong pressure on the pipeline and rupture it. As of the date of this annual report, 10 lawsuits related to this incident are active for an approximately worth of COP$7.8 billion.

 

Environmental Administrative Proceedings

 

As of December 2017, Ecopetrol S.A. was party to 215 environmental administrative proceedings, of which 197 were initiated before 2017, and 18 during 2017. During 2017, 5 proceedings were concluded, in 3 of them we were subject to monetary fines through Resolutions issued in 2017; DTP 1330 October 5, DGL 796, September and DGL 411 May 10. However, these last two proceedings were suspended due to the replenishment of resources. It is not possible for us to determine whether the pending proceedings could have a material effect on Ecopetrol.

 

Reficar Investigations

 

Reficar is a wholly owned subsidiary of Ecopetrol. According to Colombian regulations, Ecopetrol’s and Reficar’s employees are considered public servants, and as such can be held liable for negligent use or management of public resources. In this context, given that Ecopetrol is majority owned by the Colombian Government and Reficar is a wholly owned subsidiary of Ecopetrol, Ecopetrol and Reficar administer public resources.

 

As a result, Ecopetrol and Reficar employees are generally subject to the control and supervision of the following control entities, among others:

 

· The Office of the Comptroller General ( Contraloría General de la República ) oversees the adequate use of public resources and has the authority to investigate public employees or private sector employees that use or manage public resources.

 

· The Attorney General’s Office ( Procuraduría General de la Nación ) supervises compliance with applicable law by public employees and private sector employees that carry out public functions. The Attorney General’s Office investigates and disciplines individuals for compliance failures.

 

  117  

 

 

· The Prosecutor’s Office ( Fiscalía General de la Nación ) investigates potential crimes and prosecutes alleged crimes before the court in judicial proceedings.

 

The following are the most significant investigations and proceedings carried out by the aforementioned state entities:

 

1. The Office of the Comptroller General’s investigations and proceedings:

 

Because of the modifications of the schedule and budget related to Reficar’s expansion and modernization project (the “Project”), the Office of the Comptroller General initiated a special audit investigation of the Project in 2016 and delivered a final report to Reficar on December 5, 2016. The report made 36 findings most of which were related to increased costs compared to budget for services, labor and materials. As required, on January 18, 2017, Reficar submitted an action plan exposing and addressing the 36 findings in the following areas: (i) contract management, (ii) supervision of engineering standards contracted with third parties, and (iii) documentation of the control, reporting and monitoring mechanisms of subcontracts.

 

As a result of the findings described above the Office of the Comptroller General opened actions for financial responsibility ( proceso de responsabilidad fiscal ) against 36 individuals and the six companies involved in the Project, including current and former members of Ecopetrol’s Board of Directors; former members of Reficar’s Board of Directors; current and former employees of Ecopetrol; and former employees of Reficar, as well as Chicago Bridge & Iron Company N.V., CBI - Chicago Bridge & Iron company (CB&I) Americas Ltd., Chicago Bridge & Iron Company CB&I UK Limited, CBI Colombiana S.A., Foster Wheeler USA Corporation and Process Consultants Inc.

 

One current member of Ecopetrol’s Board of Directors, Joaquín Moreno Uribe, is being investigated in these proceedings.

 

These actions were initiated based on the Office of the Comptroller General’s theory that lower than expected profitability at Reficar could have been caused by modifications to the schedule, and for the increase of the budget of the Project. As of the date of this annual report, Reficar has no liability under this proceeding.

 

While the content and status of the investigations remains confidential, we can report that Reficar and several of its employees have cooperated with and provided the information required by the department of the Office of the Comptroller General in charge of leading the investigation.

 

In January 2017, the Office of the Comptroller General initiated another special audit in Reficar and delivered a final report to Reficar on July 12, 2017. In this report the Office of the Comptroller General concluded that, in their opinion, Reficar’s 2016 Financial Statements do not reasonably represent, in all material aspects, the entity’s financial position as of December 31, 2016.

 

On February 2, 2018, the Legal Accounts Commission of the National House of Representatives of the Republic of Colombia informed Reficar that the House of Representatives decided, through Resolution No. 2713, that it would not close the General Budget, Treasury Account or the National Balance Sheet for the 2016 fiscal year, since the 2016 Financial Statements of several state entities, among them Reficar, had received a negative opinion from the Office of the Comptroller General. Pursuant to Resolution No. 2713, Colombian control entities have been ordered to initiate disciplinary, fiscal and/or penal investigations.

 

Reficar’s external auditors issued an unqualified opinion on Reficar’s financial position as of December 31, 2016 and 2017. As of the date of this annual report, such auditors have not informed Reficar that there has been any change to their opinion.

2. The Attorney General’s Office investigations:

 

Reficar has been officially informed that the Attorney General’s Office currently has one ongoing investigation relating to the Project. The investigation initiated in 2012 against members of Reficar’s Board of Directors at the time, as well as certain current and former officers of Reficar.

 

On September 12, 2017 the Attorney General’s Office issued a list of charges related to the failure to fulfill some of their duties as administrators and/or for acting “ultra vires” in the exercise of their functions against: (i) Javier Genaro Gutiérrez (Ecopetrol CEO, 2007-2015); (ii) Felipe Laverde (Reficar General Counsel, 2009-March 2017); (iii) Pedro Rosales (Ecopetrol Downstream Executive Vice President, 2008-2015); (iv) Diana Constanza Calixto (Ecopetrol Head of the Corporate Finance Unit, 2009-2014) and (vi) Reyes Reinoso Yañez (Reficar CEO, 2012-2016). The Attorney General’s Office closed the case against the rest of the members of Reficar’s Board of Directors and the rest of the current and former officers of Reficar.

 

3. The Prosecutor’s Office investigations:

 

The Prosecutor’s Office is conducting an investigation. In connection therewith, between July 25 and August 2, 2017 the Prosecutor’s Office indicted the following individuals with charges, the majority of which are related to offenses against the public administration and illegal interest in the execution of agreements:

 

(i) Orlando José Cabrales Martínez (Reficar CEO, 2009-2012); (ii) Reyes Reinoso Yañez (Reficar CEO, 2012-2016); (iii) Felipe Laverde Concha (Reficar General Counsel, 2009-March 2017); (iv) Pedro Alfonso Rosales Navarro (Ecopetrol Downstream Executive Vice President, 2008-2015); (v) Masoud Deidehban (CBI Executive Project Director); (vi) Phillip Asherman (CBI CEO) and (vii) Carlos Lloreda (Reficar’s statutory auditor from 2013-2015.)

 

The arraignment hearing is scheduled to take place on May 30, 2018.

 

Prosecutor’s Office has not yet made public the factual basis for such charges, and accordingly we are not in a position to predict the outcome of investigation or the disposition of any of the charges.

 

As of the date of this annual report, to the best of Ecopetrol’s knowledge, the financial statements continue to fairly represent the financial and operational condition of the Company in all material aspects and its internal controls remain effective.

 

Ecopetrol and Reficar have cooperated closely and extensively with the control entities in furthering their investigations and will continue to monitor the status and development of these investigations.

 

Additionally, on May 9, 2017, Ecopetrol’s Audit and Risk Committee retained a U.S.-based outside law firm to commence a third-party investigation into the matters set forth in the Prosecutor’s Office announcement. The results were presented in December 2017 to Ecopetrol’s Audit and Risk Committee. This investigation concluded that to date there has been no evidence of possible unlawful acts that affect Ecopetrol’s internal control over the financial reporting of the Company, on the allegations made by the Prosecutor’s Office.

 

In March 2016, Reficar filed a Request for Arbitration before the International Chamber of Commerce (the “ICC”), against Chicago Bridge & Iron Company N.V., CB&I (UK) Limited, and CBI Colombiana S.A. (jointly, “CB&I”) concerning a dispute related to the Engineering, Procurement, and Construction Agreements entered into by and between Reficar and CB&I for the expansion of the Cartagena Refinery in Cartagena, Colombia.  Reficar is the Claimant in the ICC arbitration and seeks no less than US$2 billion in damages plus lost profits.  On May 25, 2016, CB&I filed its Answer to the Request for Arbitration and Counterclaim for approximately US$106 million and COP$324,052 million.  On June 27, 2016, Reficar filed its reply to CB&I’s counterclaim denying and disputing the declarations and relief requested by CB&I.  On April 28, 2017, CB&I submitted its Statement of Counterclaim increasing its claims to approximately US$116 million and COP$387,558 million. On March 16, 2018, CB&I submitted its Exhaustive Statement of Counterclaim further increasing its claims to approximately US$129 million and COP$432,303 million (including interests).

 

  119  

 

 

The hearing before the tribunal is currently scheduled for 2019. At the conclusion of which the tribunal would render its final decision on Reficar’s and CB&I’s claims. Until then, the outcome of this arbitration is unknown.

 

Bioenergy Special Audit

 

The Office of the Comptroller General, in exercise of its fiscal monitoring duties and authority as set forth in Article 267 of the Political Constitution, has undertaken audits of the performance of the Bioenergy S.A.S. and Bioenergy Zona Franca S.A.S. investments.

 

On February 6, 2017 the Office of the Comptroller General initiated a Special Intervention (Special Audit) in order to evaluate the use of public funds in the project carried out by Bioenergy Zona Franca S.A.S. and Bioenergy S.A. On July 10, 2017 the Office of the Comptroller General issued its final report with 15 findings related to: (i) acquisition, lease payments and the use of agricultural lands, (ii) loss of profits due to the project´s delay; and (iii) execution of contracts related with the building, commissioning and start-up of the industrial plant and the agricultural component of the project. As required, Bioenergy has commenced a remediation plan to address the findings.

 

6. Shareholder Information

 

6.1        Shareholders’ General Assembly

 

Our Shareholders’ General Assembly was held on March 23, 2018 and the following matters were approved:

 

· The plan for distribution of the Company’s profits, which establishes the distribution of an ordinary dividend per share of eighty nine pesos (COP$89) to be paid to minority shareholders in one installment on April 19, 2018 and in two installments to the majority shareholder, 50% on April 19, 2018 and 50% on September 17, 2018.

 

· Amendment of our bylaws. For further information please see the section Corporate Governance—Bylaws .

 

· Appointed Ernst & Young as external auditor of Ecopetrol for fiscal year 2018.

 

· The bylaws were amended in the General Shareholders Assembly held on March 23, 2018.

 

· The new composition of the Board of Directors for the year 2018 as follows:

Ø Joaquín Moreno Uribe

 

  120  

 

 

Ø Hernando Ramírez Plazas (nominated by the hydrocarbon producing provinces)

 

Ø Carlos Gustavo Cano Sanz (nominated by the minority shareholders with the greatest share participation)

 

6.2        Dividend Policy

 

In 2018, as a result of the solid financial position of the Company, the Board of Directors approved as a dividend policy consisting of the distribution of between 40% and 60% of the adjusted net income of the Company of each fiscal year. For this purpose, the Board of Directors shall asses the macroeconomic environment, the cash projection for achieving strategy goals and growth plans, while maintaining an appropriate financial flexibility. This policy cannot exceed the maximum amount to be distributed and should keep the Company’s debt metrics in line with an investment grade rating. The maximum amount to be distributed is the profits available to shareholders (net income after release and appropriation for legal, fiscal and occasional reserves).

 

Pursuant to Colombian law, dividend distribution to our shareholders must be approved by a 78% majority of the shares represented in the corresponding General Shareholders Assembly. In the absence of this special majority, at least 50% of the net profits must be distributed.

 

On March 23, 2018, our shareholders at the ordinary General Shareholders Assembly approved an ordinary dividend of 55% of our net income for the fiscal year ended December 31, 2017.  On March 31, 2017, our shareholders at the ordinary General Shareholders Assembly approved an ordinary dividend of 40% of our net income before the impairment of non-current assets (net of taxes) for the fiscal year ended December 31, 2016. Given that the fiscal year ended December 31, 2015 resulted in a net loss for Ecopetrol S.A., our shareholders at the General Shareholders Assembly held on March 31, 2016, approved that there was no distribution of profits for the fiscal year ended December 31, 2015. Pursuant to Article 456 of the Code of Commerce the Company absorbed the net loss for the fiscal year ended December 31, 2015 through its legal reserve.  In 2015 there was no dividend distribution and in 2016 the shareholders approved the distribution of 40% of our net income before the impairment of non-current assets (net of taxes).  See section Financial Review—Liquidity and Capital Resources—Dividends .

 

Ecopetrol S.A. is required to have legal reserves equal to 50% of its subscribed capital.  If the legal reserves are less than 50% of subscribed capital, we will contribute 10% of net income to our legal reserves every year until our legal reserves meet the required level.

 

6.3        Market and Market Prices

 

Starting on August 2010, our ADSs began trading on the Toronto Stock Exchange (“TSX”) under the symbol “ECP.” On February 17, 2016, we announced the application for voluntary delisting from the Toronto Stock Exchange after in an ordinary meeting held on January 27, 2016, during which the Board of Directors made the decision to delist from the TSX. This decision was based on the Board of Director’s assessment of, among other factors, the limited trading activity of our ADRs in Canada, a liquid market for our ADRs on the NYSE and for our ordinary shares on the local Colombian Stock Exchange (Bolsa de Valores de Colombia), both of which enable interested investors to acquire a participation in Ecopetrol S.A. The time and administrative efforts associated with maintaining the listing of the ADRs on the TSX were also taken into account. On March 2, 2016, Ecopetrol’s ADRs were delisted from the TSX. After delisting from the TSX, the ADRs have continued to trade on the NYSE and the ordinary shares have continued to trade in the Colombian stock market. Therefore, the Company continues to be subject to United States, Canadian as well as Colombian reporting and corporate governance obligations. Ecopetrol has applied to the Alberta Securities Commission and Ontario Securities Commission to cease being a reporting issuer in Canada. As of the date of this annual report, these applications are under review by such entities and we are awaiting for final resolution on the matter, until a decision is reached, Ecopetrol continues to comply with its reporting responsibilities under its reporting issuer status in Canada.

Registration and Transfer of Shares

 

Under Colombian law, transfers of shares must be registered on the issuer’s stock ledger. Only those holders registered on the stock ledger are considered by law as shareholders. Ecopetrol’s shares are in electronic form, other than those shares held by the Nation, which are in physical form.

 

Transfers of shares evidenced in electronic form required to be negotiated through the Colombia Stock Exchange. In Colombia, only the relevant stockbrokers called sociedades comisionistas de bolsa are authorized to make the transfers of shares through the Colombia Stock Exchange. The transfers of shares are registered in the Centralized Security Deposit ( Depósito Centralizado de Valores ) or DECEVAL, through the relevant stockbrokers. DECEVAL records the share transfer on its systems, in order to make the corresponding registration in the issuer stock ledger.

 

Under Colombian legislation, if a transfer of shares for a value equivalent to or higher than 66,000 UVR (the UVR was COP$252.3767 as of December 31, 2017) must be made through the BVC if the shares are registered with the BVC. Otherwise, shareholders can freely negotiate a transfer of shares.

 

Nevertheless, pursuant to Decree 2555 of 2010 article 6.15.1.1.2 the following transfers are not required to be executed through the BVC:

 

· Transfers between shareholders who are considered to be the same beneficial owner;

 

· Transfers of shares owned by financial institutions, under supervision of Superintendence of Finance, that are in a liquidation process;

 

· Repurchases of shares by the issuer;

 

· Property delivered in lieu of payment, or payment of money or other valuable property, different than the amount owed or demanded, in exchange for the extinguishment of the debt;

 

· Transfers of shares made by the Nation or the Financial Institutions Warranty Fund ( Fondo de Garantías de Instituciones Financieras ) or FOGAFIN;

 

· Transfers of shares issued abroad by Colombian companies, provided they take place outside Colombia;

 

· Transfers of shares issued by foreign companies, offered through a public offer in Colombia, provided that they take place outside Colombia; and

 

  123  

 

 

· Any other transaction specifically authorized by the Superintendence of Finance to take place outside the BVC.

 

For the purposes described above, multiple transfer transactions made within one hundred twenty (120) calendar days, between the same parties on shares of the same issuer and under similar conditions, are treated as a single transfer.

 

6.4        Ecopetrol ADR Program Fees

 

Fees and Charges That a Holder of Our ADSs May Have to Pay, Either Directly or Indirectly

 

JPMorgan Chase Bank, N.A., our Depositary, may charge each person to whom ADSs are issued, including, without limitation, issuances against deposits of shares, issuances in respect of share distributions, rights and other distributions, issuances pursuant to a stock dividend or stock split declared by us or issuances pursuant to a merger, exchange of securities or any other transaction or event affecting the ADSs or Deposited Securities, and each person surrendering ADSs for withdrawal of Deposited Securities in any manner permitted by the Deposit Agreement or whose ADSs are cancelled or reduced for any other reason, US$5.00 for each 100 ADS (or any portion thereof) issued, delivered, reduced, cancelled or surrendered, as the case may be. The Depositary may sell (by public or private sale) sufficient securities and property received in respect of a share distribution, rights and/or other distribution prior to such deposit to pay such charge.

 

The Depositary collects its fees for issuance and cancellation of ADSs directly from investors depositing common shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The Depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The Depositary may collect its annual fee for Depositary services by deduction from cash distributions, or by directly billing investors, or by charging the book-entry system accounts of participants acting for them.

The following additional charges may be incurred by holders of ADRs, by any party depositing or withdrawing common shares or by any party surrendering ADSs and/or to whom ADSs are issued (including, without limitation, issuance pursuant to a stock dividend or stock split declared by us or an exchange of stock regarding the ADRs or the Deposited Securities or a distribution of ADSs), whichever is applicable:

 

· A fee of U.S.$0.05 or less per ADS for any cash distribution made pursuant to the Deposit Agreement;

 

· A fee for the distribution of securities (or the sale of securities in connection with a distribution), such fee being in an amount equal to the fee for the execution and delivery of ADSs which would have been charged as a result of the deposit of such securities (treating all such securities as if they were common shares) but which securities or the net cash proceeds from the sale thereof are instead distributed by the Depositary to those holders of ADRs entitled thereto;

 

· An aggregate fee of up to US$0.05 per ADS per calendar year (or portion thereof) for services performed by the Depositary in administering the ADRs (which fee may be charged on a periodic basis during each calendar year and shall be assessed against holders of ADRs as of the record date or record dates set by the Depositary during each calendar year and shall be payable in the manner described in the next succeeding provision);

 

· A fee for the reimbursement of such fees, charges and expenses as are incurred by the Depositary and/or any of the Depositary’s agents (including, without limitation, the custodian and expenses incurred on behalf of holders of ADRs in connection with compliance with foreign exchange control regulations or any law or regulation relating to foreign investment) in connection with the servicing of our common shares or other Deposited Securities, the sale of securities (including, without limitation, Deposited Securities) and the delivery of Deposited Securities or otherwise in connection with the Depositary’s or its custodian’s compliance with applicable law, rule or regulation (which fees and charges shall be assessed on a proportionate basis against registered holders of ADRs as of the record date or dates set by the Depositary and shall be payable at the sole discretion of the Depositary by billing such holders of ADRs or by deducting such charge from one or more cash dividends or other cash distributions);

 

  124  

 

 

· Stock transfer or other taxes and other governmental charges;

 

· SWIFT, cable, telex and facsimile transmission and delivery charges incurred at the request of a holder of ADRs;

 

· Transfer or registration fees for the registration of transfer of Deposited Securities on any applicable register in connection with the deposit or withdrawal of Deposited Securities; and

 

· In connection with the conversion of foreign currency into U.S. dollars, the Depositary shall deduct out of such foreign currency the fees, expenses and other charges charged by it or the Depositary’s agent (which may be a division, branch or affiliate) so appointed in connection with such conversion. The Depositary and/or the Depositary’s agent may act as principal for such conversion of foreign currency. Such charges may at any time and from time to time be changed by agreement between us and the Depositary.

 

We will pay all other charges and expenses of the Depositary and any agent of the Depositary (except the custodian) pursuant to agreements from time to time between us and the Depositary. The fees described above may be amended from time to time.

 

Fees and Other Direct and Indirect Payments Made by the Depositary to Us

 

Our Depositary has agreed to reimburse us for certain expenses we incur that are related to establishment and maintenance of the ADR program, including investor relations expenses and exchange application and listing fees. In 2015, reimbursements were made in the amount of approximately US$2,069,202 for expenses related to investor relations activities. In 2016, reimbursements were made in the amount of approximately US$2,366,395 for expenses related to investor relations activities. In 2017, reimbursements were made in the amount of approximately US$2,220,290 for expenses related to investor relations activities.

 

6.5        Taxation

 

6.5.1        Colombian Tax Considerations

 

The following is a general description of the Colombian tax considerations for investments in common shares in Colombia or for the purchase of ADSs, in a foreign securities market. This description is based on applicable law in effect as of the date of this annual report is issued, which may be subject to changes.

 

Prospective purchasers of common shares or ADSs should consult their own tax advisors for a detailed analysis of the tax consequences in Colombia, resulting from the acquisition, ownership and disposition of common shares or ADSs.

 

General Rules

 

Colombian entities and individuals who are deemed to be residents within the Colombian national territory for Colombian tax purposes are subject to Colombian income tax on their worldwide income. Foreign entities and individuals who are not deemed to be residents in Colombia, as well as their permanent establishment in Colombia for tax purposes are subject to income tax in Colombia only with respect to their national-source income, which is generally defined as income obtained from (i) the rendering of services inside Colombian territory, (ii) the exploitation of tangible and intangible assets in Colombia, and (iii) the sale of tangible or intangible assets that are located inside Colombian territory at the time of the sale Double taxation treaties signed by Colombia, if applicable, may provide for special regulations regarding income tax.

 

  125  

 

 

Dividends paid by Colombian companies, as well as profits distributed by branches/permanent establishments are deemed Colombian income. However, whether they are taxed or not depends on an imputation system set forth in articles 48 and 49 of the Colombian Tax Code (hereinafter “CTC”). According to this system, dividends are taxable when paid out of non-taxed profits, in which case a 35% withholding applies when paid to non-resident shareholders. Conversely, they are non-taxable when paid out of taxed profits, provided that the shareholder qualifies as a Colombian company.

 

Notwithstanding the above, one of the novelties introduced by Law 1819 of December 29 of 2016 (the “Tax Reform”) was the creation of a new dividends tax that applies on all dividend distributions to Colombian individuals or to any type of non-resident shareholder, absent any specific treaty or exception, regardless that dividends are paid from taxed or non-taxed profits. According to the Tax Reform, dividend payments made to foreign shareholders will be subject to a 5% withholding. This new tax will only apply to dividends paid from profits accrued as from fiscal year 2017.

 

Note that the dividend tax will apply simultaneously with the aforementioned imputation system. Accordingly, dividends paid from non-taxed profits will be subject to a 35% withholding for income tax, and an additional 5% dividend tax on the balance. This means that the overall burden in this scenario is 38.25% (e.g. $100 *35% = $35, plus $65 * 5% = $3.25).

 

Relief or reduced tax rates may apply under an applicable treaty to avoid double taxation, but the application of any such rules must be analyzed on a case-by-case basis.

 

For Colombian tax purposes, an individual is considered to be a Colombian resident when he/she meets any of the following criteria:

 

(i) He/she remains in Colombia continuously or discontinuously for more than 183 calendar days within any given 365-consecutive-day term;

 

(ii) He/she is related to the Colombian government’s foreign service or to individuals who are in the Colombian government’s foreign service and who, by virtue of the Vienna Conventions on diplomatic and consular relations, are exempted from taxes during the time of their service; or

 

(iii) He/she is a Colombian national and:

 

- Has a spouse or permanent companion, or dependent children, who are tax residents in Colombia, or

 

- 50% or more of his or her total income is Colombian source income, or

 

- 50% or more of his or her assets are managed in Colombia, or

 

- 50% or more of his or her assets are deemed to be located or possessed in Colombia, or

 

- Has failed to provide proof of residency in another country (different from Colombia) upon previous official request by the Colombian tax office, or

 

- He/she has a tax residency in a country considered by the Colombian government to be a low tax jurisdiction or a tax haven.

 

Law 1739 of 2014 clarifies that Colombian nationals who meet any of the following requirements, will not be deemed as tax residents:

 

(i) If more than 50% of his or her annual income, has its source in the jurisdiction where he or she is domiciled and whose country of domicile is not Colombia.

 

  126  

 

 

(ii) If more than 50% of his/her assets are located in the jurisdiction where he or she is domiciled and whose country of domicile is not Colombia.

 

For purposes of Colombian taxation, an entity is deemed to be a “national” or a “Colombian entity” and, therefore, subject to taxation in Colombia on its worldwide income, if it meets any of the following criteria:

 

(i) It has its place of effective management, in Colombia during the corresponding year or taxable period;

 

(ii) It has its main domicile in the Colombian territory; or

 

(iii) It has been incorporated in Colombia, in accordance with Colombian laws.

 

Pursuant to the Colombian Tax Code, a foreign company or non-resident individual has a permanent establishment in Colombia when said company or individual performs activities in Colombia through: (1) a fixed place of business (i.e., branches, factories or offices), or (2) an individual who is not an independent agent empowered to execute agreements on behalf of the foreign company. As noted above, permanent establishments are considered Colombian taxpayers in connection with the Colombian-source income and Colombian-source taxable gains attributed to said permanent establishment. A foreign company or entity will not be deemed to have a permanent establishment by the sole fact that it acts through a broker or any other independent agent. In addition, passive-income generating activities, such as dividends, royalties and interests, typically do not qualify as entrepreneurial and are not deemed to create permanent establishments.

 

Tax Treatment of a Non-Colombian Entity and a Non-Resident Individual of Colombia Who Purchases an ADS in a Foreign Securities Market

 

Dividends

 

As a general rule, dividends paid to foreign companies, foreign entities or non-resident individuals who are investing in ADSs which underlying assets are Colombian shares are treated as Colombian-source income and are thus subject to Colombian income tax.

 

To avoid double taxation, dividends paid by Colombian entities are not subject to income tax at the shareholder level when they are paid out of corporate profits that have been previously taxed at the corporate level. As of taxable year 2017, a withholding tax on dividends is triggered for dividends paid to non-resident shareholders. Withholding tax rates on dividends varies as follows: (i) a new 5% dividend tax for dividends distributed out of profits already taxed at the company’s level; (ii) 35% withholding tax rate for dividends distributed out of profits not taxed at the company’s level, plus the new 5% dividend tax rate after having applied and deducted the initial 35% withholding. As of fiscal year 2017, for Colombian individuals, the new dividends tax will apply 5% or 10% depending on the dividend amount. Dividends tax will be applicable to profits generated from fiscal year 2017 onwards. Finally, dividends paid to local corporations are not subject to this new dividend tax.

 

Further to the above, the applicable withholding tax rate for an entity or a non-resident individual investing through a Foreign Funds Administration Account (FFAA) is 25%, since its investment qualifies as portfolio investments and the dividends that are distributed by the Colombian entity are not taxed at the corporate level (assuming that the dividends cannot be attributed to a permanent establishment in Colombia belonging to the shareholder). These foreign shareholders subject to this withholding tax are not required to file an income tax return in Colombia.

 

In addition to the above, the new dividend tax will apply at a 5% rate.

 

Taxation of Capital Gains from the Sale of ADSs

 

Capital gains obtained from the sale of ADSs by non-Colombian entities, Colombian individuals who are non-residents in Colombia and foreign non-resident individuals, are not subject to income tax in Colombia as such sale does not generate Colombian-source income to the extent that the ADSs are not deemed to be sourced in Colombia.

 

  127  

 

 

If the holder of the ADSs who is a non-resident entity, a Colombian individual who is not a resident in Colombia or a foreign non-resident individual, decides to surrender the ADSs and withdraw the underlying common shares, it is arguable that such transaction does not generate a capital gain subject to income tax in Colombia. However, different interpretations may be adopted by the Colombian Tax Authorities on this matter.

 

Tax Treatment in Colombia of a Non-Colombian Entity and a Non-Resident Individual of Colombia Who Purchases Ecopetrol’s Shares in Colombia’s Securities Market

 

Dividends

 

As a general rule, dividends paid to foreign companies, foreign entities, or to non-resident individuals in Colombia, who are investing in Colombian shares directly or through a FFAA, are treated as national-source income; thus, they are subject to Colombian income tax.

 

To avoid double taxation, dividends are not subject to income tax at the shareholder level when they are paid out of corporate profits that have been previously taxed at the corporate level. However, as of taxable year 2017, a withholding tax on dividends is triggered for dividends paid to non-resident shareholders. Withholding tax rates on dividends varies as follows: (i) 5% dividend tax for dividends distributed out of profits already taxed at the company´s level; and (ii) 35% withholding tax for dividends distributed out of profits not taxed at the company´s level, plus an additional 5% dividend tax after having applied and deducted the initial 35% withholding. As of fiscal year 2017, for Colombian individuals, dividends will be taxed between 5% and 10% depending on the dividend amount. Dividends tax will be applicable to profits generated from fiscal year 2017 onwards. Finally, dividends paid to local corporations are not subject to the new dividend tax.

 

For fiscal year 2017 if the shareholder is a non-resident entity or a non-resident individual investing directly, it will be taxed upon distribution, by means of the withholding tax mechanism, provided that its investment does not qualify as portfolio investments and dividends that are distributed are not taxed at the corporate level. In this case, dividends will be subject to a 35% withholding tax.

 

Non-resident entities or non-resident individuals will be taxed upon distribution by means of the withholding tax mechanism, provided that their investments qualify as portfolio investments (i.e., investing through a FFAA) and dividends that are distributed by the Colombian entity are not taxed at the corporate level. In this case, pursuant to Article 18-1 of the Colombian Tax Code, the applicable withholding tax rate is 25%, assuming that the dividends cannot be attributed to a permanent establishment in Colombia belonging to the shareholder. These foreign shareholders subject to this withholding tax are not required to file an income tax return in Colombia.

 

In addition to the above, the new dividend tax will apply at a 5% rate.

 

Taxation of Capital Gains for the Sale of Shares

 

Pursuant to Article 36-1 of the Colombian Tax Code, capital gains derived from the sale of shares listed on the BVC and owned by the same beneficial owner, are deemed as non-taxable income in Colombia, provided that the shares sold during the same taxable year do not represent more than 10% of the outstanding shares of the listed company. Pursuant to Article 18 of Decree 2634 of 2012, sellers of shares are not required to file an income tax return for the transfer of securities that are listed in the National Registry of Securities and Issuers ( Registro Nacional de Valores y Emisores ) as long as the foreign investment is treated as a portfolio investment according to article 3 of Decree 2080 of 2000.

 

If the above-mentioned requirements are not met, the capital gain obtained in the sale of shares is subject to income tax or capital gains tax, under the following rules:

 

· The gain or loss arising therefrom will be the difference between the sale price and the tax basis of the shares. As a general rule, the tax basis of shares is equal to the price paid for such shares ( i.e. , cost of acquisition).

 

  128  

 

 

· The applicable tax rate and the withholding tax rate have to be determined on a case-by-case basis. Generally, if the shares have been owned for at least two years, the profits from the sale will qualify as capital gains taxable at 10%, otherwise, profits will qualify as ordinary income taxable, approximately 37% for fiscal year 2018, and 33% as from fiscal year 2019.

 

Tax Treatment of Non-Residents Who Purchase Ecopetrol’s Shares in the BVC Market and Exchange Them for ADSs

 

Dividends

 

Payment of dividends by Colombian entities to foreign companies, foreign entities or to non-resident individuals who are investing in ADSs which underlying assets are Colombian shares or in Colombian shares directly are subject to the tax treatment described above.

 

Taxation on Capital Gains for the Sale of Shares

 

If the holder of the Colombian shares is a non-resident entity, a Colombian individual who is not a resident in Colombia or a foreign non-resident individual, and such holder decides to exchange such common shares for ADSs, it is arguable that such transaction should not generate a capital gain subject to income tax in Colombia. However, different interpretations may be adopted by the Colombian tax authorities on this matter. For instance, assuming that the exchange of securities is treated as a sale of Ecopetrol’s shares, the seller would be subject to the tax treatment described above in connection with the taxation of capital gains for the sale of shares. Absent any specific rules or regulations addressing this specific situation, a case-by-case analysis would be necessary.

 

6.5.2        U.S. Federal Income Tax Consequences

 

This summary describes the principal U.S. federal income tax consequences of the ownership and disposition of common shares or ADSs, but it does not purport to be a comprehensive description of all of the U.S. tax consequences that may be relevant to a decision to hold or dispose of common shares or ADSs. This summary applies only to purchasers of common shares or ADSs who will hold the common shares or ADSs as capital assets for U.S. federal income tax purposes and does not apply to special classes of holders such as dealers in securities or currencies, holders whose functional currency is not the U.S. dollar, holders of ten percent or more of our shares (taking into account shares held directly or through depositary arrangements by vote or by value), tax-exempt organizations, financial institutions, holders liable for the alternative minimum tax, securities traders who elect to account for their investment in common shares or ADSs on a mark-to-market basis, partnerships or other pass-through entities or arrangements and investors therein, insurance companies, U.S. expatriates, persons that purchase or sell common shares or ADSs as part of a wash sale for tax purposes, and persons holding common shares or ADSs in a hedging transaction or as part of a straddle, conversion or other integrated transaction for U.S. federal income tax purposes. The statements regarding U.S. tax law set forth in this summary are based on the Internal Revenue Code of 1986, as amended, which we call the “Code,” its legislative history, existing and proposed U.S. Treasury regulations, published rulings and court decisions all as in force on the date of this annual report, and changes to such law subsequent to the date of this annual report may affect the tax consequences described herein (possibly with retroactive effect). This summary is also based in part on the representations of the Depositary and the assumption that each obligation in the Deposit Agreement and any related agreement will be performed in accordance with its terms.

 

Each holder is encouraged to consult such holder’s tax advisor concerning the overall tax consequences to it, including the consequences under laws other than U.S. federal income tax laws, of an investment in common shares or ADSs.

 

In this discussion, references to a “U.S. Holder” are to a beneficial owner of a common share or an ADS that is for U.S. federal income tax purposes (1) an individual citizen or resident of the United States, (2) a corporation, or any other entity taxable as a corporation, organized under the laws of the United States, any state thereof or the District of Columbia, (3) an estate whose income is subject to U.S. federal income tax regardless of its source, or (4) a trust if (i) a United States court can exercise primary supervision over the trust’s administration and one or more United States persons are authorized to control all substantial decisions of the trust or (ii) it has in effect a valid election under applicable U.S. Treasury regulations to be treated as a U.S. person.

 

  129  

 

 

For U.S. federal income tax purposes, holders of ADSs generally will be treated as owners of the common shares represented by such ADSs.

 

This discussion does not address any aspect of U.S. federal taxation other than U.S. federal income taxation (such as the estate and gift tax or the Medicare tax on net investment income). Holders of common shares or ADSs should consult their own tax advisor regarding the U.S. federal, state and local and other tax consequences of owning and disposing of common shares and ADSs in their particular circumstances.

 

Distributions on Common Shares or ADSs

 

A distribution to U.S. Holders made by us of cash or property with respect to common shares or ADSs generally will be treated as a dividend for U.S. federal income tax purposes to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Distributions in excess of our current or accumulated earnings and profits, as determined for U.S. federal income tax purposes, will be treated first as a tax-free return of capital reducing such U.S. Holder’s adjusted tax basis in the common shares or ADSs. Any distribution in excess of such adjusted tax basis will be treated as capital gain and will be either long-term or short-term capital gain depending upon whether the U.S. Holder held the common shares or ADSs for more than one year. Distributions of additional common shares or ADSs to U.S. Holders that are part of a pro rata distribution to all of our shareholders generally will not be subject to U.S. federal income tax. We do not maintain calculations of our earnings and profits under U.S. federal income tax principles, and, therefore, except as described in the previous sentence, U.S. Holders should expect that any distributions generally will be reported as dividends for U.S. federal income tax purposes. As used below, the term “dividend” means a distribution that constitutes a dividend for U.S. federal income tax purposes.

 

The amount of any distribution will include the amount of any Colombian tax withheld on the amount distributed, and the amount of a distribution paid in Colombian Pesos will be measured by reference to the exchange rate for converting Colombian Pesos into U.S. dollars in effect on the date the distribution is received by the Depositary (or by a U.S. Holder in the case of a holder of common shares) regardless of whether the payment is in fact converted into U.S. dollars. If the Depositary (or U.S. Holder in the case of a holder of common shares) does not convert such Colombian Pesos into U.S. dollars on the date it receives them, generally, any gain or loss resulting from currency exchange fluctuations during the period from the date the dividend payment is included in income to the date the payment is converted into U.S. dollars will be treated as ordinary income or loss and will not be eligible for the special tax rate applicable to qualified dividend income (as discussed below). The gain or loss generally will be income or loss from sources within the United States for foreign tax credit limitation purposes. Dividends paid by us will not be eligible for the dividends received deduction allowed to corporations under the Code.

 

If you are a non-corporate U.S. Holder, dividends that constitute qualified dividend income will be taxable to you at the preferential rates applicable to long-term capital gains provided that you meet certain holding requirements. Dividends paid on the ADSs will be treated as qualified dividend income if (1) the ADSs are readily tradable on an established securities market in the United States and (2) we were not, in the year prior to the year in which the dividend was paid, and are not, in the year in which the dividend is paid, a passive foreign investment company (PFIC). The ADSs are listed on the New York Stock Exchange, and will qualify as readily tradable on an established securities market in the United States so long as they are so listed. Based on our audited financial statements and relevant market and shareholder data, we believe that we were not treated as a PFIC for U.S. federal income tax purposes with respect to our 2017 taxable year. In addition, based on our audited financial statements and our current expectations regarding the value and nature of our assets, the sources and nature of our income, and relevant market and shareholder data, we do not anticipate becoming a PFIC for the 2018 taxable year. However, this conclusion is a factual determination that is made annually and thus may be subject to change. Based on existing guidance, it is not clear whether dividends received with respect to the common shares will be treated as qualified dividends. In addition, the U.S. Treasury has announced its intention to promulgate rules pursuant to which holders of ADSs or common shares and intermediaries through whom such securities are held will be permitted to rely on certifications from issuers to treat dividends as qualified for tax reporting purposes. Because such procedures have not yet been issued, it is not clear whether we will be able to comply with them. Holders of ADSs and common shares should consult their own tax advisers regarding the availability of the reduced dividend tax rate in the light of the considerations discussed above and their own particular circumstances.

 

  130  

 

 

A U.S. Holder will be entitled, subject to a number of complex limitations and conditions, to claim a U.S. foreign tax credit in respect of any Colombian income taxes withheld on dividends received on common shares or ADSs. U.S. Holders who do not elect to claim a credit for any foreign income taxes paid during the taxable year may instead claim a deduction in respect of such Colombian income taxes provided the U.S. Holder elects to deduct (rather than credit) all foreign income taxes for that year. Dividends received with respect to the common shares or ADSs will be treated as foreign source income, subject to various classifications and other limitations. For the purposes of the U.S. foreign tax credit limitations, the dividends paid with respect to our common shares or ADSs generally will constitute “passive category income” for most U.S. Holders. The rules relating to computing foreign tax credits or deducting foreign income taxes are extremely complex, and U.S. Holders are urged to consult their own independent tax advisers regarding the availability of foreign tax credits with respect to any Colombian income taxes withheld.

 

Sale, Exchange or Other Taxable Dispositions of Common Shares or ADSs

 

A U.S. Holder generally will recognize capital gain or loss upon the sale, exchange or other taxable disposition of common shares or ADSs in an amount equal to the difference between the U.S. dollar value of the amount realized on the sale, exchange or other taxable disposition of the common shares or ADSs and the U.S. Holder’s adjusted tax basis, determined in U.S. dollars, in the common shares or ADSs. Any gain or loss will be long-term capital gain or loss if the common shares or ADSs have been held for more than one year. Certain non-corporate U.S. Holders (including individuals) may be eligible for preferential rates of U.S. federal income tax in respect of long-term capital gains. The deductibility of capital losses is subject to limitations under the Code.

 

If you are a U.S. Holder of common shares or ADSs, the initial tax basis of your common shares or ADSs will be the U.S. dollar value of the Colombian Peso-denominated purchase price determined on the date of purchase. If the common shares or ADSs are treated as traded on an “established securities market,” a cash basis U.S. Holder, or, if it elects, an accrual basis U.S. Holder, will determine the dollar value of the cost of such common shares or ADSs by translating the amount paid at the spot rate of exchange on the settlement date of the purchase. Such an election by an accrual basis U.S. Holder must be applied consistently from year to year and cannot be revoked without the consent of the Internal Revenue Service (“IRS”). If you convert U.S. dollars to Colombian Pesos and immediately use that currency to purchase common shares or ADSs, such conversion generally will not result in taxable gain or loss to you.

 

With respect to the sale or exchange of common shares or ADSs, the amount realized generally will be the U.S. dollar value of the payment received determined on (1) the date of receipt of payment in the case of a cash basis U.S. Holder and (2) the date of disposition in the case of an accrual basis U.S. Holder. If the common shares or ADSs are treated as traded on an “established securities market,” a cash basis taxpayer, or, if it elects, an accrual basis taxpayer, will determine the U.S. dollar value of the amount realized by translating the amount received at the spot rate of exchange on the settlement date of the sale.

 

Deposits and withdrawals of common shares in exchange for ADSs, and ADSs for common shares generally will not result in the realization of gain or loss for U.S. federal income tax purposes.

 

Backup Withholding and Information Reporting

 

In general, dividends on common shares or ADSs, and payments of the proceeds of a sale, exchange or other taxable disposition of common shares or ADSs, paid within the United States, by a U.S. payor through certain U.S.-related financial intermediaries to a U.S. Holder are subject to information reporting and may be subject to backup withholding at a current rate of 24% unless the holder (1) establishes that it is a corporation or other exempt recipient or (2) with respect to backup withholding, provides an accurate taxpayer identification number and certifies that it is a U.S. person and that no loss of exemption from backup withholding has occurred.

 

  131  

 

 

Backup withholding is not an additional tax. The amount of any backup withholding tax 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, provided that the required information is timely furnished to the IRS. A U.S. Holder generally may obtain a refund of any amounts withheld under the backup withholding rules that exceed its U.S. federal income tax liability by timely filing a refund claim with the IRS.

 

U.S. Tax Considerations for Non-U.S. Holders

 

A holder or beneficial owner of common shares or ADSs that is not a U.S. Holder for U.S. federal income tax purposes (a “non-U.S. Holder”) generally will not be subject to U.S. federal income or withholding tax on dividends received on common shares or ADSs, unless the dividends are “effectively connected” with the non-U.S. Holder’s conduct of a trade or business within the United States. In such a case a non-U.S. Holder generally will be taxed in the same manner as a U.S. Holder. In the case of “effectively connected” dividends received by a corporate non-U.S. Holder, the corporate non-U.S. Holder may, under certain circumstances, be subject to an additional “branch profits tax” at a 30% rate.

 

A non-U.S. Holder of common shares or ADSs will not be subject to U.S. federal income or withholding tax on gain realized on the sale of common shares or ADSs, unless (i) the gain is “effectively connected” with the non-U.S. Holder’s conduct of a trade or business in the United States, or (ii) in the case of gain realized by an individual non-U.S. Holder, the non-U.S. Holder is present in the United States for 183 days or more in the taxable year of the sale and certain other conditions are met. In the case of “effectively connected” gains realized by a corporate non-U.S. Holder, the corporate non-U.S. Holder may, under certain circumstances, be subject to an additional “branch profits tax” at a 30% rate.

 

Although non-U.S. Holders generally are exempt from backup withholding and information reporting requirements, a non-U.S. Holder may be required to comply with certification and identification procedures in order to establish its exemption from information reporting and backup withholding.

 

6.6        Exchange Controls and Limitations

 

Payments in foreign currency with respect to certain foreign exchange transactions including international investments between Colombian residents and non-Colombian residents must be conducted through the foreign exchange market. Therefore, any foreign currency income or expense under the ADRs must be completed through the appropriate channels of the foreign exchange market. Transactions conducted through the foreign exchange market are made at market rates freely negotiated with authorized foreign exchange intermediaries (local banks, financial corporations, administrators and others). As of September 25, 1999 the Colombian foreign exchange regime is structured under the system of free flotation of the exchange rate whereby market forces determine the level of exchange rate from time to time.

 

Foreign portfolio investments must be made through authorized foreign exchange investment management companies. Only brokerage firms, trust companies and investment management companies, subject to the inspection and supervision of the Superintendence of Finance, are allowed to make investments in the local Colombian market on behalf of foreign investors. Such brokerage firms, trust companies and investment management companies also act as the foreign investors’ local representatives for tax and foreign exchange purposes.

 

Colombian law provides that the Colombian Central Bank may intervene in the foreign exchange market at its own discretion at any time (i.e. it may limit the remittance of dividends whenever the international reserves fall below an amount equal to three months of imports). Additionally, from time to time, the Colombian government introduces amendments to the International Investment Statute. Hence, we cannot assure you that the Colombian Central Bank will not intervene in the future imposing restrictions to the free convertibility system currently applicable in Colombia. See section Risk Review—Risk Factors—Risks Related to Colombia’s Political and Regional Environment .

 

  132  

 

 

Registration of Foreign Investment Represented in Underlying Shares

 

Colombia’s International Investment Statute and the regulations issued by the Colombian Central Bank, which have been amended from time to time through related decrees and regulations, govern the manner in which non-Colombian resident entities and individuals can invest in Colombia and participate in the Colombian securities markets. Among other requirements, the International Investment Statute and Colombian Central Bank regulations mandate registration of foreign investment transactions with the Colombian Central Bank and specify procedures to authorize and administer such foreign investment transactions. Additionally, pertinent information related to foreign investment transactions must be updated on a regular basis (yearly or monthly, depending on the type of information).

 

Under the International Investment Statute and Colombian Central Bank regulations, the failure of a foreign investor to report or register with the Colombian Central Bank foreign exchange transactions relating to investments in Colombia on a timely basis may (i) prevent the investor from obtaining remittance rights, (ii) constitute an exchange control infraction, and (iii) result in financial sanctions.

 

Notwithstanding the regulations described above, foreign investors who acquire ADRs are not required to directly register this investment with Colombian authorities. Holders of ADRs will benefit from the registration to be obtained by the local custodian for our common shares underlying the ADRs in Colombia. Such registration allows the custodian to convert dividends and other distributions with respect to the common shares into foreign currency and remit the proceeds abroad. If investors in ADRs choose to surrender their ADRs and withdraw common shares, they must retain an administrator, who will act as a local representative for the investments, and register their investments in common shares as a portfolio investment through said local representative. The local representative is the brokerage firm, trust company or investment management company that acts on behalf of the holders of the ADRs in Colombia, and the request for registration is made by them.

 

Colombian residents who acquire ADRs and either receive profits from this investment, surrender their ADRs or liquidate their investment in ADRs must register these operations with the Colombian authorities and comply with applicable regulations through its Colombian brokerage firm.

 

In obtaining its own foreign investment registration, an investor who surrenders its ADRs and sells common shares may incur expenses and/or suffer delays in the application process. Investors would only be allowed to transfer dividends abroad or transfer funds received as distributions relating to our common shares after their foreign investment registration procedure with the Colombian Central Bank has been completed. In addition, the Depositary’s foreign investment registration may also be adversely affected by future legislative changes, but its rights to transfer dividends abroad or profits arising from distributions relating to our common shares must be maintained according to Colombian law and foreign investment treaties entered into by Colombia in force at the time of the registration of the investment, except when Colombia’s international reserves fall below an amount equivalent to three months’ worth of imports. Prospective purchasers of common shares or ADSs should consult their own foreign exchange advisors.

 

6.7        Exchange Rates

 

On April 16, 2018, the Representative Market Exchange Rate was COP$2,705.34 per US$1.00. The Federal Reserve Bank of New York does not report a noon-buying rate for Colombian Pesos. The Superintendencia Financiera , or Superintendence of Finance, calculates the Representative Market Exchange Rate based on the weighted averages of the buy and sell foreign exchange rates quoted daily by foreign exchange rate market intermediaries including financial institutions for the purchase and sale of U.S. dollars. The Superintendence of Finance also calculates the Representative Market Exchange Rate for each month for purposes of preparing financial statements and converting amounts in foreign currency to Colombian Pesos.

 

The following table sets forth the high, low, average and period-end exchange rate for Colombian Peso/U.S. dollar Representative Market Exchange Rate for each of the last five years and for the last six months.

As of February 20, 2018, we had 39 registered holders and as of March 31, 2018 we had 15,907 beneficiaries of common shares, or ADSs representing common shares, in the United States.

 

Changes in the Capital of the Company

 

There are no conditions in our bylaws governing changes in our capital stock that are more stringent than those required under Colombian law, with the exception that the Nation must hold a minimum of 80% of our capital stock at all times.

 

6.9        Enforcement of Civil Liabilities

 

We are a Colombian company. Most of our Directors and executive officers and some of the experts named in this annual report reside outside the United States. All or a substantial portion of our assets and the assets of these persons are located outside of the United States. As a result, it may not be possible for you to affect service of process within the United States upon us or these persons who are residents in Colombia or to enforce against us or these persons who are residents in Colombia judgments in U.S. courts obtained in such courts predicated upon the civil liability provisions of the U.S. federal securities laws. Colombian courts will enforce a U.S. judgment predicated on the U.S. securities laws through a procedural system known under Colombian Law as “exequatur.” The Colombian Supreme Court will enforce a foreign judgment, without reconsideration of the merits only if the judgment satisfies the requirements set forth in Articles 605 through 607 of Law 1564 of 2012 ( Código General del Proceso ) which entered into force on January 1, 2016, pursuant to Acuerdo No. PSAA15-10392, of October 1, 2015, issued by the Colombian Superior Council of the Judiciary ( Consejo Superior de la Judicatura ), as follows:

 

  134  

 

 

· A treaty exists between Colombia and the country where the judgment was granted relating to the recognition and enforcement of foreign judgments or, in the absence of such treaty, there is reciprocity in the recognition of foreign judgments between the courts of the relevant jurisdiction and the courts of Colombia;

 

· The foreign judgment does not relate to “in rem rights” vested in assets that were located in Colombia at the time the suit was filed;

 

· The foreign judgment does not contravene or conflict with Colombian laws relating to public order other than those governing judicial procedures;

 

· The foreign judgment, in accordance with the laws of the country where it was rendered, is final and is not subject to appeal;

 

· A duly legalized copy of the judgment (together with an official translation into Spanish if the judgment is issued in a foreign language) has been presented to the Supreme Court of Colombia;

 

· The foreign judgment does not refer to any matter upon which Colombian courts have exclusive jurisdiction;

 

· No proceeding is pending in Colombia with respect to the same cause of action, and no final judgment has been awarded in any proceeding in Colombia on the same subject matter and between the same parties;

 

· In the proceeding commenced in the foreign court that issued the judgment, the defendant is served in accordance with the laws of such jurisdiction and in a manner reasonably designated to give the defendant an opportunity to defend against the action; and

 

· The legal requirements pertaining to the exequatur proceedings have been observed;

 

The United States and Colombia do not have a bilateral treaty providing for automatic reciprocal recognition and enforcement of judgments in civil and commercial matters. The Colombian Supreme Court has in the past accepted that reciprocity exists when it has been proven that either a U.S. court has enforced a Colombian judgment or that a U.S. court would enforce a foreign judgment, including a judgment issued by a Colombian court. However, such enforceability decisions are considered by Colombian courts on a case-by-case basis.

 

Proceedings for enforcement of a money judgment by attachment or execution against any assets or property located in Colombia are within the exclusive jurisdiction of Colombian courts and such proceedings are conducted in Spanish. All parties affected by a foreign judgment in exequatur proceedings must be summoned to the exequatur proceedings in accordance with the rules that apply to the Colombian courts. In the course of such proceedings, both the plaintiff and the defendant are afforded the opportunity to request that evidence be collected in connection with the requirements listed above. In addition, before the judgment is rendered, each party may file final allegations in support of such party’s position regarding the above-mentioned requirements.

 

Assuming that a foreign judgment complies with the standards set forth in the preceding paragraphs and the absence of any condition referred to above that would render a foreign judgment not subject to recognition under Colombian law, such foreign judgment would be enforceable in Colombia in an enforcement proceeding under the laws of Colombia, provided that the Colombian Supreme Court has previously granted exequatur upon the foreign judgment.

7. Corporate Governance

 

Since 2004, Ecopetrol S.A. has voluntarily adopted transparency, governance and control practices to facilitate corporate governance in order to generate confidence among stakeholders and ensure the sustainability of its business.

 

The corporate governance practices at Ecopetrol S.A.:

 

· Promote and guarantee all stakeholders transparency, objectivity and competitiveness.

 

· Add value to the company and attract investors.

 

· Protect shareholders, investors and stakeholders rights.

 

· Encourage financial markets confidence.

 

· Accomplish the highest corporate governance standards.

 

Statement of the Nation as Majority Shareholder

 

Ecopetrol’s majority shareholder (the Nation, represented by the Ministry of Finance and Public Credit), is unilaterally committed to protect the interests of the minority shareholders in the following topics:

 

· Composition of Board of Directors : including in its list of candidates a Representative for hydrocarbon producing departments operated by Ecopetrol and a Representative for the minority shareholders, who will be chosen by the 10 shareholders with the largest stock participations.

 

According to corporate governance practices recommended by the OECD, organization to which Colombia is in the process of access, the National Government begun to implement the practice of reducing the participation of Directors with a ministerial level in Ecopetrol’s Board of Directors. Thus, in 2018 in the General Shareholders’ Assembly, the National Government nominated two (2) non-independent Directors none of which has a ministerial rank.

 

· Dividend policy : guaranteeing the right of each shareholder to receive his pro rata dividends in accordance with Colombian law.

 

· Issues not included in the agenda of extraordinary meetings of the General Shareholders Assembly : permitting a vote on those initiatives submitted by one or more shareholders representing at least 2% of the subscribed shares of the company.

 

· Asset disposal : ensuring that any asset disposal of an amount equal or higher than 15% of the stock exchange capitalization of Ecopetrol is discussed and decided by the General Shareholders’ Assembly and that the Nation will only vote affirmatively if the vote of minority shareholders is equal to or exceeds 2% of the shares subscribed by shareholders other than the Nation.

 

7.1        Bylaws

 

The Bylaws of Ecopetrol S.A. are contained in Public Deed No. 5314 of December 14, 2007, issued by the Second Notary of Bogotá; amended by Public Deed No. 560 of May 23, 2011, issued by the Notary Forty- Six of Bogotá, Deed No. 666 of May 7, 2013, issued by the Notary Sixty-Five of Bogotá, and Deed No. 1049 of May 19, 2015, issued by the Notary Second of Bogotá.

General Shareholder’s Meeting

 

Shareholders’ meetings may be ordinary or extraordinary. Ordinary meetings will take place in our legal domicile located in Bogota, Colombia, within the first three months following the end of each fiscal year, on the day and at the time set forth in the notice for the General Shareholders Assembly. The call for the General Shareholders Assembly is published on the Ecopetrol S.A. website and in a newspaper of wide circulation 30 calendar days prior to the date on which the meeting will take place and on the Sunday previous to the meeting, must be published at Ecopetrol S.A.’s website www.ecopetrol.com.co.

 

In the General Shareholders Assembly, our Board of Directors and the external auditor are appointed and our annual financial statements, profit distribution, audit and management reports, including our corporate governance report and sustainability report, and any other matter provided under applicable law or our corporate bylaws are approved.

 

Extraordinary meetings of shareholders may be called by our Board of Directors, by our president or chief executive officer, by our external auditor, or by shareholders holding at least 5% of the shares outstanding, or when unforeseen or urgent needs of the Company require it. Calls to extraordinary meetings should be made at least 15 calendar days prior to the date of the meeting, with the exception of the case where the Law requires a greater time between the summons and the meeting. Such a call is published on the Ecopetrol S.A. website and in a newspaper of wide circulation. The meeting notice must specify the agenda for the meeting.

 

The required quorum for both ordinary and extraordinary meetings is a plural number of shareholders representing 50% plus one of the subscribed shares entitled to vote and decisions are approved with a majority of the members present. This quorum is exempted in the case of “second-call meetings,” which may take place when a meeting fails to obtain the required quorum and is called within a period between 10 business days and 30 business days from the first date, in which case decisions may be adopted by a majority of the shares present regardless of the number represented.

 

Decisions made at ordinary and extraordinary shareholders’ meeting must be approved by a plural number of shareholders representing the majority of the shares present. Colombian law requires supermajorities in the following cases:

 

· The vote of at least 70% of the shares present and entitled to vote at the ordinary shareholders’ meeting is required to approve the issuance of stock not subject to preemptive rights;

 

· The vote of at least 78% of the shares represented entitled to vote is required to approve the distribution of the annual net profits. In the absence of this special majority, at least 50% of the net profits must be distributed. If the sum of all legal reserves (statutory, legal and optional) exceeds the amount of the outstanding capital, the Company must distribute at least 70% of the annual net profits;

 

· The vote of at least 80% of the shares represented is required to approve the payment of dividends in shares; and

 

· The vote of 100% of the outstanding and issued shares is required to replace a vacancy on the Board of Directors without applying the electoral quotient system.

 

Shareholders may be represented by proxies provided that the proxy: (1) is in writing (faxes and electronic documents are valid), (2) specifies the name of the representative, (3) specifies the date or time of the meeting for which the proxy is given and (4) includes other information specified by the applicable law. Proxies granted abroad do not require legalization or an apostille.

During our ordinary annual shareholders’ meeting, our employees and Directors are only allowed to represent their own shares, unless they act as legal representatives.

 

Preference Rights and Restrictions Attaching to Our Shares

 

We have only one class of stock without special rights or restrictions (ordinary shares). Our shareholders do not have any type of preemptive rights.

 

Under Commercial Colombian law, our shareholders have the following economic privileges and voting rights:

· To sell the shares, known as right of withdrawal ( derecho de retiro ), if a corporate restructuring affects the economic or voting rights of the shareholders in the terms and conditions established under Colombian law.

 

Our bylaws and corporate governance code provide additional rights to our minority shareholders. These rights include:

 

· Sale of Assets . For a ten-year period counted from the date of subscription of the declaration of the Nation dated February 16, 2018 or until the Nation loses its status as majority shareholder, the Nation guarantees that any sale of 15% or more of our assets requires the approval of the General Shareholders Assembly and that the Nation would only be allowed to vote its shares in favor of the proposal if 2% or more of our minority shareholders accept the proposal.

 

· Candidate List . Pursuant to our bylaws and Law 1118 of 2006, the Nation will include in its candidate list for election of members of the Board of Directors one member selected by the departments that produce hydrocarbons. In addition, pursuant to the declaration of the Nation dated February 16, 2018, the Nation will include in its candidate list for election of members of the Board of Directors one member selected by the ten largest minority shareholders. The minority shareholders’ right to select a candidate loses its effect when minority shareholders, according to their share participation, name a member to our Board of Directors.

 

· Extraordinary Meetings . Our bylaws and corporate governance code provide that the entity exercising permanent control over Ecopetrol must instruct the Company’s CEO or External Auditor to call an extraordinary meeting of the Company’s shareholders when so requested by a plurality of shareholders holding at least 5% of the total number of outstanding shares.

Special audits cannot be made of documents that contain scientific, technological or statistical information of our Company, or agreement that gives us competitive and economic advantages over our competitors, or in respect of any document related to intellectual property. Shareholders also have the right to propose good corporate governance recommendations to the office for the protection of investors.

· Others . Pursuant to our bylaws, shareholders holding at least 5% of the total number of shares outstanding may propose recommendations to our Board of Directors pertaining to the management of our Company.

Amendments to Rights and Restrictions to Shares

Restrictions on Change of Control Mergers, Spin-offs or Transformations of the Company

 

Under Colombian law and our bylaws, the General Shareholders Assembly has full authority to approve any mergers, spin-offs or transformations.

The shareholding composition of the Company, indicating at least the twenty (20) people with the greatest number of shares, is disclosed on Ecopetrol’s website at www.ecopetrol.com.co . Colombian securities regulations set forth the obligation to disclose any material event or hecho relevante . Any transfer of shares equal or greater than 5% of our capital stock, or any legal entity or individual acquiring a percentage of shares that would make him the beneficial owner of 5% or more of our capital stock, is a material event, and therefore, must be disclosed to the Superintendence of Finance. The regulation includes other criteria in order to identify when to report a material event other than the situations described in the previous sentence.

7.3.1        Board Practices

 

Our Board of Directors is composed of nine members and is responsible for, among other things, establishing our general business policies. The majority of the Board of Directors must be independent, and must be elected pursuant to the criteria set out in paragraph two, Article 44, Law 964, 2005, and in accordance with the procedure determined in Decree 3923, 2006, or any other provisions that regulate, amend, replace or add such regulations. In addition, pursuant to our bylaws and in accordance with the procedures described therein, our majority shareholder must include, in its list of candidates for the last two seats in the Board of Directors, the name of one individual jointly proposed by departments that produce hydrocarbons and one individual jointly proposed by the ten minority shareholders with the highest equity participation. According to Colombian law, the members of the Board of Directors must be elected by the General Shareholders Assembly in accordance with a proportional representation system similar to cumulative voting (through an electoral quota voting system). The number of votes required to fill each position is calculated by dividing the number of possible votes by the number of open board positions. The members of the Board of Directors may be elected without an electoral quota voting system when there is unanimity. Pursuant to our bylaws, positions on our Board of Directors are filled either by person or by position and, beginning in 2019, Directors will be elected for a two-year term. Currently, we have one Director appointed by his position: The General Director of State Participations of the Ministry of Finance and Public Credit. Our current Directors were elected at the General Shareholders Assembly held on March 23, 2018. Members of the Board may be reelected indefinitely.

 

Our CEO is appointed by the Board of Directors and has two alternates. The CEO is elected for a two-year term, may be reelected indefinitely and freely removed prior to the expiration of his term. In accordance with our bylaws, the Board of Directors must evaluate the annual performance of the CEO and such results must be published in Ecopetrol’s web page or in an alternative media vehicle.

 

The compensation of our Directors is set exclusively by the shareholders at the General Shareholders Assembly. Directors are compensated for attending board meetings and committee meetings. A Board meeting requires a quorum of at least five members and decisions are approved with a majority of the Directors present. In the practice a consensus decision making operates in the Board.

 

Under Colombian law, a director or executive officer must abstain from participating in any transaction that may result in a conflict of interest or that involves competing with the company, unless authorized at a General Shareholders Assembly. The general shareholders may approve or reject the transaction giving rise to the conflict of interest with the vote of the majority of the shares present at the General Shareholders Assembly. If the director or executive officer who has the conflict is a shareholder, his or her vote must be excluded. We disclose conflicts of interest of our employees, executive officers and Directors in our annual reports.

 

  142  

 

 

Neither our bylaws nor our corporate governance code provide a retirement age for our Directors. Under our bylaws, there is no requirement for a person to have a minimum number of shares to be elected as a Director. Colombian law provides that Directors willing to sell or purchase shares in our Company need prior authorization from the entire Board of Directors. Colombian law does not impose any limitation as to the number of shares that may be acquired by a Director.

 

7.3.2        Board Committees

 

Pursuant to our bylaws, our Board of Directors has the ability to constitute the committees it considers necessary. The Board of Directors currently has four committees (audit and risk committee, corporate governance and sustainability committee, compensation and nomination committee and business committee. These committees establish guidelines, set specific actions and evaluate and submit proposals designed to improve performance in the areas under their supervision and control. The committees are comprised of members of the Board of Directors who are also appointed by the same members. The chairman of each of the committees must be an independent Director. In addition to applicable regulations, the committees also have their own specific regulations that establish their purposes, duties and responsibilities.

Our audit and risk committee, which must be comprised of at least three members, all of them independent Directors, is our highest internal control body and provides support to our Board of Directors on risk, accounting and financial matters. It is in charge of guaranteeing the design, implementation and supervision of our internal control over financial reporting. It also ratifies the annual hydrocarbons reserves report and provides support for our Board on analyzing topics related to financial matters, risks, control environment and the assessment of the Company’s internal and external auditors.

 

All committee members are required to be knowledgeable in accounting matters and at least one of them is required to be an expert in financial and accounting matters.

 

Our Board of Directors has determined that Jaime Ardila Gómez qualifies as an “audit committee financial expert” and he is independent under the definition of “independent” applicable to us under the rules of the NYSE.

 

The audit and risk committee approves on a case-by-case basis any engagement of our external independent auditors to provide services different than those related to auditing our financial statements. Occasionally, the audit and risk committee will have no doubt that these additional services do not compromise the external auditor’s independence. When in doubt, the committee will request the opinion of the internal auditor.

 

Compensation and Nomination Committee

 

Our compensation and nomination committee, which must be comprised of at least three members, including at least one independent director, provides general guidelines for the selection and compensation of our executive officers and employees.

 

Corporate Governance and Sustainability Committee

 

Our corporate governance and sustainability committee, which must be comprised of at least three members, including at least one independent director, makes proposals to our Board of Directors to ensure and supervise the fulfillment of our good corporate governance and sustainability practices in accordance with our corporate governance code.

 

Business Committee

 

Our business committee, which must be comprised of at least five members, including at least one independent Director, assists our Board in analyzing potential business ventures. Based on its delegation of power, the committee studies and analyzes capital expenditure policies, major investment projects, strategy, new business and other matters that would help us move forward in our efforts toward the consolidation of our strategy. The primary criteria used in the committee’s decision-making process are the optimization of our portfolio and the proper allocation of our resources.

 

7.4        Compliance with NYSE Listing Rules

 

The following is a summary of the significant differences between our corporate governance practices and those required for U.S. companies under the NYSE listing standards.

 

NYSE Standards   Our Corporate Governance Practices
Director Independence    
The majority of the board of directors must be independent.  §303A.01.  ”Controlled companies,” which would include Ecopetrol if we were a U.S. issuer, are exempt from this requirement.  A controlled company is one in which more than 50% of the voting power is held by an individual, group or another company, rather than the public.  §303A.00.   Pursuant to our bylaws, the majority of the Board of Directors must be independent.  As of the date of this annual report, we have seven independent Directors and two non-independent Directors.

 

  144  

 

 

NYSE Standards   Our Corporate Governance Practices
Executive Sessions    
The non-management directors of each listed company must meet at regularly scheduled executive sessions without management.  §303A.03.   A comparable rule does not exist under Colombian law.  Except for our audit and risk committee, our Board of Directors does not meet without management.
     
Nominating/Corporate Governance and Sustainability Committee  
A nominating/corporate governance and sustainability committee composed entirely of independent directors is required.  The committee must have a charter specifying the purpose, duties and evaluation procedures of the committee.  §303A.04.  “Controlled companies” are exempt from these requirements.  §303A.00.   Colombian law does not require the establishment of a nominating and a corporate governance and sustainability committee composed entirely of independent directors.  Pursuant to our board charter, these committees shall be composed of a majority of independent Directors.
     
Compensation Committee    
A compensation committee composed entirely of independent directors is required, which must evaluate and approve executive officer compensation.  The committee must have a charter specifying the purpose, duties and evaluation procedures of the committee.  §303A.05.  “Controlled companies” are exempt from this requirement.  §303A.00.   Colombian law does not require the establishment of a compensation committee composed entirely of independent directors.  Pursuant to our board charter, this committee shall be composed of a majority of independent Directors.
     
Audit and Risk Committee    
An audit committee with a minimum of three independent directors satisfying the independence and other requirements of Rule 10A-3 under the Exchange Act and the more stringent requirements under the NYSE standards is required.  §§303A.06 and 303A.07.   According to Law 964 of 2005, Colombian companies that are authorized to issue securities by the Superintendence of Finance must have an audit committee that satisfies the requirements of Law 964 of 2005, including its minimum number of members, independence criteria and audit related duties.  Our audit and risk committee is composed entirely of independent Directors, and the committee meets the requirements of Law 964 of 2005 and Rule 10A-3 under the Exchange Act.
     
Equity Compensation Plans    
Equity compensation plans and all material revisions thereto require shareholder approval, subject to limited exemptions.  §§303A.08 and 312.03.   Under Colombian law, no similar right to vote on equity compensation plans and material revisions thereto is given to shareholders.  We do not give our shareholders the right to vote on equity compensation plans and material revisions thereto.
     
Corporate Governance Guidelines    
Listed companies must adopt and disclose corporate governance guidelines.  §303A.09.   The Superintendence of Finance recommends the adoption of corporate governance guidelines to all Colombian issuers.  According to Superintendence of Finance Circular No. 028, 2014, the adoption of corporate governance guidelines is voluntary.  Listed companies must annually publish a corporate governance survey comparing their corporate governance standards with those recommended by the Superintendence of Finance.  Our corporate governance code and our survey of the adoption of Colombian practices are available on our website at http://www.ecopetrol.com.co .

 

  145  

 

 

NYSE Standards   Our Corporate Governance Practices
Code of Ethics for Directors, Officers and Employees    
Corporate governance guidelines and a code of business conduct and ethics is required, with disclosure of any waiver for directors or executive officers.  The code must contain compliance standards and procedures that will facilitate the effective operation of the code.  §303A.10.   We have adopted a code of ethics which complies with applicable U.S. and Colombian law.  Our code of ethics applies to our chief executive officer, chief financial officer, principal accounting officer, persons performing similar functions and to all of the employees, members of the Board of Directors, suppliers, and contractors of Ecopetrol S.A. and its corporate group.  Our code of ethics is available on our website at http://www.ecopetrol.com.co

7.8        Controls and Procedures

 

Disclosure Controls and Procedures

 

As required by Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as of December 31, 2017, we evaluated the design and effectiveness of our financial disclosure controls and procedures under the supervision and participation of our management, including our Chief Executive Officer and Chief Financial Officer. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even if effective, disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

 

  149  

 

 

Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that as of the end of the period covered by this annual report, our disclosure controls and procedures were effective to provide reasonable assurance that the information required to be disclosed in the reports that we file and submit under the Securities Exchange Act of 1934 is recorded, summarized and reported as and when required and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

 

Management’s Annual Report on Internal Control over Financial Reporting

 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15(d)-15(f) under the Securities Exchange Act of 1934. Our internal control over financial reporting is a process designed under the supervision of our Chief Executive Officer and Chief Financial Officer, and affected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external reporting purposes in accordance with generally accepted accounting principles, and it includes those policies and procedures that:

 

· pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of our assets;

 

· 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 are being made only in accordance with authorization of our management and directors; and

 

· provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, effective control over financial reporting cannot, and does not, provide absolute assurance of achieving our control objectives. Also, projection of any evaluation of the effectiveness of the internal controls to future periods is 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.

 

As of the year ended December 31, 2017, our management conducted an assessment of the effectiveness of our internal control over financial reporting in accordance with the criteria established in the publication “Internal Control – Integrated Framework (2013)”, issued by the Committee of the Sponsoring Organizations of the Treadway Commission, as well as the rules set by the SEC in its Final Rule “Management’s Report on Internal Control Over Financial Reporting and Certification of Disclosure in Exchange Act Periodic Reports.”

 

Based on the assessment performed, management concluded that our internal control over financial reporting was effective as of the end of the period covered by this annual report.

 

The effectiveness of our internal control over financial reporting has been audited by Ernst & Young Audit S.A.S., an independent registered public accounting firm, as stated in their audit report accompanying our consolidated financial statements.

In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company at December 31, 2017 and 2016, and the results of its operations and its cash flows for the years ended December 31, 2017 and 2016, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

Opinion on Internal Control over Financial Reporting

 

We have audited Ecopetrol S.A. and subsidiaries’ internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Ecopetrol, S.A. and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on the COSO criteria .

 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statements of financial position of the Company as of December 31, 2017 and 2016, the related consolidated statements of profit or loss, comprehensive income, changes in equity and cash flows for the years ended December 31, 2017 and 2016, and the related notes and financial statement schedules on exhibits 1 and 2, and our report dated April 19, 2018 expressed an unqualified opinion thereon.

 

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 Annual 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.

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

1. Reporting entity

 

Ecopetrol S.A. (“Ecopetrol”) is a mixed economy company, of a commercial nature, incorporated in 1948 in Bogotá - Colombia, parent company of the Ecopetrol Business Group. Its corporate purpose is to conduct commercial or industrial activities related to the exploration, exploitation, production, refining, transportation, storage, distribution and commercialization of hydrocarbons and their derivatives and products, directly or through its subsidiaries (collectively referred to as "Ecopetrol Business Group").

 

11.51% of Ecopetrol shares are publicly traded on the Stock Exchanges of Colombia and New York. The remaining shares (88.49% of the total outstanding shares) are owned by the Colombian Ministry of Finance and Public Credit.

 

The address of the main office of Ecopetrol is Bogotá - Colombia, Carrera 13 No. 36 - 24.

 

2. Basis for presentation

 

2.1 Statement of compliance and authorization of financial statements

 

These consolidated financial statements of Ecopetrol and its subsidiaries as of December 31, 2017 and 2016 and for the years ended December 31, 2017, 2016 and 2015 have been prepared in accordance with International Financial Reporting Standards (IFRS), issued by the International Accounting Standards Board (IASB).

 

Accounting policies described in Note 4 have been applied consistently in all periods.

 

These consolidated financial statements were approved and authorized for issuance by the Board of Directors of Ecopetrol on April 19, 2018.

 

2.2 Basis for consolidation

 

The consolidated financial statements were prepared by consolidating all companies set out in Exhibit 1, which are those over which Ecopetrol exercises direct or indirect control. Control is achieved when the Group:

 

§ Has power over the investee (including rights to manage relevant activities);
§ Is exposed, or has the rights, to variable returns from its involvement with the investee; and
§ Has the ability to use its power to affect its operational returns. This instance occurs when the Group has less than a majority of the voting rights of an investee, and it still has the power over the investee to provide it with the practical ability to direct the relevant activities of the investee unilaterally. The Group considers all relevant facts and circumstances in assessing whether or not the Company’s voting rights in an investee are sufficient or not to give it power, including:

 

a) The percentage of the Group's voting rights relative to the size and apportionment of the shares of other vote holders;
b) Potential voting rights held by the Group, other vote holders or other parties;
c) Rights arising from other contractual arrangements; and
d) Any additional facts and circumstances that indicate that the Group has, or does not have, the current ability to direct the relevant activities, at the time that decisions need to be made, including voting patterns at previous shareholders´ meetings.

 

Subsidiaries are consolidated from the date on which control is obtained until the date that such control ceases.

 

  F- 11  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

All inter-company assets and liabilities, equity, income, expenses and cash flows relating to transactions between entities of the Ecopetrol Business Group were eliminated on consolidation. Unrealized losses are also eliminated. Non-controlling interest represents the proportion of profit, other comprehensive income and net assets in subsidiaries that are not attributable to Ecopetrol shareholders.

 

The following subsidiaries were incorporated in 2017:

 

a) Esenttia Resinas del Perú SAC: wholly-owned subsidiary in Refining whose corporate purpose is the commercialization of polypropylene resins and master batches in Peru.
b) ECP Hidrocarburos México S.A. de CV : wholly-owned subsidiary in Exploration and Production, engaged in operating oil contracts in Mexico, starting with blocks 6 and 8 of Round 2.1 in shallow waters.

 

2.3 Measurement basis

 

The consolidated financial statements have been prepared on a historical cost basis, except for financial assets and liabilities that are measured at fair value through profit or loss and/or changes in other comprehensive income at the end of each reporting period, as explained in the accounting policies included below.

 

Historical cost is generally based on fair value of the consideration given in exchange for goods and services.

 

The fair value is the price that would be received from selling an asset or that would be paid for transferring a liability among market participants, in an orderly transaction, on the date of measurement. When estimating the fair value, the Ecopetrol Business Group uses assumptions that market participants would use for pricing an asset or liability at current market conditions, including risk assumptions.

 

2.4 Functional and presentation currency

 

The consolidated financial statements are presented in Colombian Pesos, which is the Ecopetrol’s functional currency. For each Group entity its functional currency is determined based of the main economic environment where it operates.

 

The statements of profit or loss and cash flows of subsidiaries with functional currencies different from Ecopetrol S.A.’s functional currency are translated at the exchange rates on the dates of the transaction or based on the monthly average exchange rate. Assets and liabilities are translated at the closing rate and other equity items are translated at exchange rates at the time of the transaction. All resulting exchange differences are recognized in other comprehensive income. On disposal of all or significant part of a foreign operation, the cumulative translation adjustment related to the particular foreign operation is reclassified to profit or loss.

 

The financial statements are presented in Colombian pesos rounded up to the closest million unit (COP 000,000) except when otherwise indicated.

 

2.5 Foreign currency

 

Transactions in foreign currencies are initially recorded by the Group’s entities at their respective functional currency spot rates at the transactions date. Monetary items denominated in foreign currencies are translated at the functional currency spot rates prevailing at the reporting date. Differences arising on settlement or translation or monetary items are recognized in profit or loss, in financial results, net, except those resulting from the conversion of loans and borrowings designated as cash flow hedges or net investment in a foreign operation hedge, which are recognized in other comprehensive income within equity. When the hedged item affects the financial results, exchange differences accumulated in equity are reclassified to profit or loss as part of operating results.

 

  F- 12  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

Non-monetary items measured at fair value that are denominated in a foreign currency are translated using the exchange rates prevailing on the date when the fair value is determined. The gain or loss arising on translation of non-monetary items measured at fair value is treated in line with the recognition of the gain or loss on the change in fair value of the item. 

 

2.6 Classification of assets and liabilities as current and non-current

 

The Ecopetrol Business Group presents assets and liabilities in the consolidated statement of financial position based on whether assets are classified as current or non-current.

 

An asset or liability is classified as current when:

 

§ It is expected to be sold or consumed in the ordinary course of business;
§ Held mainly for the purpose of trading;
§ Expected to mature in twelve months or less; and,
§ Cash or a cash equivalent, unless the exchange of such asset or liability is restricted or to be used to settle a liability more than twelve months after the reporting period; or
§ In the case of a liability, there is no unconditional right to defer settlement of the liability until at least twelve months after the reporting period.

 

Other assets and liabilities are classified as non-current.

 

Deferred tax assets and liabilities are classified as non-current assets and liabilities.

 

2.7 Earnings (loss) per share (basic and diluted)

 

Basic earnings (loss) per share is calculated by dividing the profit for the year attributable to equity holders of Ecopetrol S.A., the parent company, by the weighted average number of ordinary shares outstanding during the year. There is no potential dilution of shares.

 

2.8 Reclassifications

 

As of December 31, 2017, the Group changed the presentation of deferred tax assets and liabilities balances by offsetting deferred tax balances levied by the same taxation authority. As a result, the Group reclassified the corresponding amounts as of December 31, 2016 to conform them to the current year's presentation, which had an immaterial impact in the deferred tax assets and deferred tax liabilities line items as of December 31, 2016. In addition, such reclassifications did not have an impact in the statements of cash flows, profit or loss and changes in equity for the year ended December 31, 2016. See additional details in Note 10 - Taxes.

 

3. Significant estimates and accounting judgments

 

The preparation of the consolidated financial statements requires management to make judgements, estimates and assumptions that affect the reported amounts of assets, liabilities, sales revenues, costs and commitments recognized in the financial statements and the accompanying disclosures. The Group based its assumptions and estimates on parameters available when the consolidated financial statements were prepared. Uncertainty about these assumptions and estimates could result in outcomes that required a material adjustment to the carrying amount of assets or liabilities affected in future periods. Changes in estimates are adjusted prospectively in the period in which the estimate is revised.

 

  F- 13  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

In the process of applying the Group’s accounting policies, management has made the following judgments and estimates which have the most significant impact on the amounts recognized in the consolidated financial statements:

 

3.1 Oil and gas reserves

 

Hydrocarbon reserves are estimates of the amount of hydrocarbons that can be economically and legally extracted from the Group’s oil and gas properties.

 

The reserves estimation is conducted annually as of December 31 in accordance with the United States Securities and Exchange Commission (SEC) definitions and rules set forth in Rule 4-10(a) of SEC Regulation S-X and the disclosure guidelines contained in the SEC final rule - Modernization of Oil and Gas Reporting.

 

As required by current regulations, the future estimated date on which a field will no longer produce for economic reasons, is based on actual costs and average of crude prices (calculated as the arithmetical average of prices on the first day of the past 12 months). The estimated date for end of production will affect the amount of reserves, unless the prices have been defined by contractual agreements; therefore, if the prices and costs change from one year to the other, the proved reserves estimate also changes. Generally, our proved reserves decrease as prices go down and increase when prices go up.

 

Reserves estimation is an inherently complex process and it involves professional judgments. Reserves estimations are prepared using geological, technical and economic factors, including projections of future production rates, oil prices, engineering data and duration and amount of future investments, and they imply a certain degree of uncertainty. These estimations reflect the regulatory and market conditions existing on the date of reporting, which could significantly differ from other conditions during the year or in future periods. Any changes in regulatory and/or market conditions and assumptions could materially affect the reserves estimation.

 

Impact of oil reserves and natural gas in depreciation and depletion

 

Changes to estimations for proven developed reserves may affect the carrying amounts of exploration and production assets, natural resources and environment, goodwill, liabilities for dismantling and depreciation, depletion and amortization. With all other variables remaining unchanged, a decrease in estimated proven reserves would increase, prospectively, depreciation, depletion and amortization costs, while an increase in reserves would reduce depreciation and amortization expenses, as depreciation, depletion and amortization charges are calculated using the units of production method.

 

Information about the carrying amounts of exploration and production assets and the amounts charged to income, including depreciation, depletion and amortization, is presented in Notes 15 and 16.

 

3.2 Asset impairment (recovery)

 

Management uses its professional judgment in assessing the existence of evidence of an expense for (recovery of) impairment, based on internal and external factors.

 

When an indicator of impairment or reversal of a prior periods impairment exists, the Group estimates the recoverable amount of the cash generating units (CGU), which is considered the greater of fair value less costs of disposal and the value in use.

 

  F- 14  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

The assessments require the use of estimates and assumptions, such as, among other factors: (1) estimation of the volumes and market value of oil and natural gas reserves; (2) production profiles for oilfields and the future production of refined and chemical products; (3) investments, taxes and future costs; (4) useful life of assets; (5) long-term prices; (6) the discount rate, which is revised annually and determined as the weighted average cost of capital (WACC); and (7) changes in environmental regulation. The recoverable amount is compared to the carrying amount of the asset, thus determining whether the asset is impaired or if the impairment recognized in prior periods should be reversed.

 

A previously recognized impairment loss is reversed only if there has been a change in the assumptions used to determine the assets or in the CGU’s recoverable amount since the last impairment loss was recognized. The reversal is limited so that the carrying amount of an asset or CGU, other than goodwill, does not exceed either its recoverable amount, or the carrying amount that would have been determined (net of amortization or depreciation) had no impairment loss been recognized for the asset or CGU in prior periods.

 

Future oil price assumptions are estimated at current market conditions. Expected production volumes, which comprise proven and unproved reserves, are used for impairment testing because management believes this to be the most appropriate indicator of expected future cash flows, which would also be considered by market participants. Reserves estimates are inherently imprecise and subject to risk and uncertainty. Furthermore, projections about unproved volumes are based on information that is necessarily less robust than what is available for mature reservoirs.

 

These estimates and assumptions are subject to risk and uncertainty. Therefore, there is a possibility that changes in circumstances will impact these projections, which may also impact the recoverable amount of assets and/or CGUs, hence, may also affect the recognition of an impairment loss or the reversal of prior period impairment amounts.

 

3.3 Exploration and evaluation costs

 

The application of the Group’s accounting policy for exploration and evaluation costs requires judgment in order to determine whether future economic benefits are likely, either from future exploitation or sale, or whether activities have not reached a stage which permits a reasonable assessment of the existence of reserves. Certain exploration and evaluation costs are initially capitalized when it is expected that commercially viable reserves will result. The Group uses its professional judgment of future events and circumstances and makes estimates in order to annually assess the generation of future economic benefits for extracting oil resources, as well as technical and commercial analyses to confirm its intention of continuing their development. Changes regarding available information such as drilling success level or changes in the project's economics, production costs, and investment levels, as well as other factors, may result in capitalized exploration drilling costs being recognized in profit or loss for the period. The expenses for dry wells is included in operating activities in the consolidated statement of cash flows.

 

3.4 Determination of cash generating units (CGU)

 

The allocation of assets in cash generating units requires significant judgment, as well as assessments regarding integration among assets, the existence of active markets, and similar exposure to market risk, shared infrastructure, and the way in which management monitors the operations. See Note 4.12 - Impairment of non-financial assets for more information.

 

3.5 Abandonment and dismantling costs of fields and other facilities

 

According to environmental and oil regulations, the Group is required to bear the costs for the abandonment of oil extraction and transportation facilities, which include the cost of plugging and abandoning wells, dismantling facilities, and environmental remediation in the affected areas.

 

  F- 15  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

Estimated abandonment and dismantling costs are recorded at the time of the installation of the assets and are reviewed annually.

 

The calculations for these estimations are complex and involve significant judgments by Management. The ultimate decommissioning costs are uncertain and cost estimates can vary in response to many factors, including changes to relevant legal requirements, the emergence of new restoration techniques or experience at other production sites. The expected timing, extent and amount of expenditure may also change, for example, in response to changes in internal cost projections, changes in reserve estimates, future inflation rates and discount rates. The Group considers that the abandonment and dismantling costs are reasonable, based on the experience of the Group and market conditions; nevertheless, significant variations in external factors used for the calculation of the estimation could significantly impact the amounts recorded in the financial statements.

 

3.6 Pension plan and other benefits

 

The determination of expenses, liabilities and adjustments relating to pension plans and other defined retirement benefits makes it necessary for management to use its judgment in the application of actuarial assumptions made in the actuarial calculation. The actuarial assumptions include estimates regarding future mortality, retirement, changes in compensation and discount rate in order to reflect the time value of money, in addition to the rate of return on the plan's assets. Due to the complexity in the valuation of these variables, as well as their long term nature, the estimated amounts are quite sensitive to any change in these assumptions.

 

These assumptions are reviewed on an annual basis and may differ materially from actual results due to changes in economic and market conditions, regulatory changes, judicial rulings, higher or lower retirement rates, or longer or shorter life expectancies among employees.

 

3.7 Goodwill impairment

 

In December of each year, the Group performs an annual impairment test on goodwill to assess if its carrying amount may be impaired.

 

The determination of the recoverable amount is described in note 4.12 and its calculation requires assumptions and estimates. The Group considers that the assumptions and estimations used are reasonable and supportable based on the current market conditions and are aligned to the risk profile of the related assets. However, if different assumptions and estimations are used, they could lead to different results. Valuation models used to determine fair value are sensitive to changes in the underlying assumptions. For example, sales volumes and prices that will be paid for the purchase of raw materials are assumptions that may vary in the future. Adverse changes in any of these assumptions could lead to the recognition of goodwill impairment.

 

3.8 Litigation

 

The Group is subject to claims relating to regulatory and arbitration proceedings, tax assessments and other claims arising in the normal course of business. Management evaluates these claims based on their nature, the likelihood that they materialize and the amounts involved, to decide on the amounts recognized and/or disclosed in the financial statements.

 

This analysis, which may require considerable judgment, includes the assessment of current legal proceedings brought against the Group and claims not yet initiated. A provision is recognized when the Group has a present obligation derived from a past event, it is likely that an outflow of resources of economic benefits will be required to settle the obligation, and a reliable estimate of the amount of such obligation can be made.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

3.9 Taxes

 

Calculation of the income tax provision requires interpretation of tax law in the jurisdictions where the Ecopetrol Business Group operates. Significant judgment is required to determine estimates for income tax on taxable profits and to evaluate the recoverability of deferred tax assets, which are based on the ability to generate sufficient taxable income during the periods in which such deferred taxes could be used or deduct.

 

To the extent that future cash flows and taxable income differ significantly from the estimates, the Group's ability to realize the deferred tax assets recorded could be affected.

 

Furthermore, changes in tax rules could limit the capacity of the Group to obtain tax deductions in future years, as well as the recognition of new tax liabilities resulting from auditing conducted by the tax authorities.

 

Tax positions taken involve a thorough assessment by Management, and are reviewed and adjusted in response to situations such as expiration in the applicability of laws, closing of tax audits, additional disclosures caused by any legal issue or a court decision relevant to a particular tax issue. The Group records provisions based on estimated potential liabilities that could be derived from a tax audit. The amount of these provisions depends on factors such as previous experience in tax audits and different interpretations of tax legislation. The actual results may differ from the estimates recorded.

 

3.10 Hedge accounting

 

The process of identifying hedging relationships between hedged items and the underlying instruments (derivative and non-derivative such as long-term foreign currency-denominated debt), and their corresponding effectiveness, requires the use of judgment by management. The Group periodically monitors the alignment between its hedge instruments and its risk management policy.

 

4. Accounting policies

 

The accounting policies indicated below have been applied consistently for all the periods presented.

 

4.1 Financial instruments

 

The classification of financial instruments depends on the nature and purpose for which the financial assets or liabilities were acquired and is determined at the time of initial recognition. Financial assets and financial liabilities are initially measured at their fair value.

 

Transaction costs that are directly attributable to the acquisition or issue of financial assets and financial liabilities (other than financial assets and financial liabilities at fair value through profit or loss) are added to or deducted from the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets or financial liabilities at fair value through profit or loss are recognized immediately in profit or loss.

 

All financial assets are initially recorded at fair value. Loans and trade receivables, other receivables and financial assets held-to-maturity are measured subsequently measured at amortized cost using the effective interest method.

 

  F- 17  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

Equity investments available for sale that do not have a market quotation price and for which fair value cannot be reliably measured are measured at cost less any impairment identified at the end of each reporting period.

 

Measurements at fair value

 

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place in the principal market of the asset or liability or in the absence of a principal market in the most advantageous market for the asset or liability.

 

All assets and liabilities for which fair value is measured or disclosed in the financial statements are classified within the following scale based on the lowest level input that is significant to the fair value measurement as a whole, as follows:

 

§ Level 1: Quoted (unadjusted) market prices in active markets for identical assets or liabilities. The fair value of the Group’s marketable securities that a quoted market price is based on Level 1 inputs.

 

§ Level 2: Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observed. Level 2 inputs include prices of similar assets, prices obtained through quotations made by stockbrokers, and prices that can be substantially corroborated with other observable data with the same contractual terms.

 

For derivative contracts for which a quoted market price is not available, fair value estimations are generally determined using models and other valuation methods, the key inputs for which include future prices, volatility estimates, price correlation, counterparty credit risk and market liquidity, as appropriate. For other assets and liabilities, fair value estimations are generally based on the net present value of expected future cash.

 

§ Level 3: Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable. The Group does not use Level-3 inputs for the measurement of financial assets and liabilities. The Group may use Level-3 inputs for the calculation the recoverable amount of certain non-financial assets for the purpose of impairment testing.

 

Effective interest rate method

 

The effective interest rate method is a method of calculating the amortized cost of a financial instrument and accounting of income or financial cost over the relevant period. The effective interest rate is the discount rate that exactly discounts estimated future cash receipts or payments (including all fees, transaction costs and other premiums or discounts) through the expected life of the financial instrument (or, when appropriate, at a shorter period), to the net carrying amount on initial recognition.

 

Impairment

 

The Group evaluates, on each reporting date, if there is objective evidence that a financial asset or group of financial assets are impaired. Financial assets are evaluated for the impairment indicators at the end of each reporting period. Financial assets are considered to be impaired when there is objective evidence that, as a result of one or more events that occurred after initial recognition, the estimated future cash flows of the asset have been affected. For financial assets measured at amortized cost, the amount of the impairment loss recognized is the difference between the asset’s carrying amount and the present value of estimated future cash flows, discounted at the financial asset’s original effective interest rate.

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

De-recognition of financial assets

 

Ecopetrol derecognizes a financial asset only upon the expiration of the contractual rights to the cash flows of the asset or, when it has transferred its rights to receive such cash flows or has assumed the obligation to pay the cash flows received in full without material delay to a third party and (a) it has transferred substantially all the risks and benefits inherent in the ownership of the financial asset or (b) it has neither transferred nor retained substantially all the risks and benefits of the asset, but has transferred control of the asset.

 

When the Group does neither transfer nor retain substantially all the risks and benefits of the asset or transfer control of the asset, the Group continues to recognize the transferred asset, to the extent of its continuing participation, and it also recognizes the associated liability.

 

4.1.1 Cash and cash equivalents

 

Cash and cash equivalents include cash on hand, financial investments that are highly liquid, bank deposits and special funds with original maturity dates of ninety days or less which are subject to an insignificant risk of changes in value.

 

4.1.2 Financial assets

 

The Group classifies its financial assets in the following categories:

 

a) Financial assets measured at fair value through profit or loss

 

Financial assets at fair value through profit or loss are financial assets held for trading and financial assets designated at the time of the initial recognition at fair value through profit or loss. Financial assets are classified as held for trading if they are acquired to be sold or repurchased in the short term. They are recognized at their fair value and losses or profits arising at the time of re-measurement are recognized in the statement of profit or loss.

 

b) Financial assets measured at fair value with changes in other comprehensive income

 

These are equity instruments of other non-controlled and non-strategic companies not allowing for any type of control or significant influence thereon and where the Group’s management does not intend to negotiate with them in the short-term. These investments are recorded at their fair value and unrealized gains or losses are recognized in other comprehensive income and credited to the available for sale reserve until the investment is derecognized, at which time, the cumulative gain or loss is recognized in other operating income, or the investment is determined to be impaired, when the cumulative loss is reclassified from the available to sale reserve to the statement of profit or loss.

 

c) Loans and receivables

 

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. Loans and receivables, including trade and other receivables, are measured initially at fair value and then at amortized cost using the effective interest rate method, less impairment.

 

  F- 19  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

Loans to employees are initially recorded using the present value of the future cash flows, discounted at the current market rate for similar loans. If the interest rate is less than the current market rate, fair value will be less than the amount of the loan. This difference is recorded as a benefit to employees.

 

4.1.3 Financial liabilities

 

Financial liabilities correspond to the financing obtained by the Group through bank credit facilities and bonds, accounts payable to suppliers and creditors.

 

Bank credit facilities and bonds are initially recognized at their fair value, net of transactions cost. After initial recognition, interest-bearing credit facilities and bonds are subsequently measured at amortized cost, using the effective interest rate method. The effective interest method amortization is included as a financial expense in the statement of profit or loss.

 

Accounts payable to suppliers and creditors are short-term financial liabilities recorded at nominal value, since it does not significantly differ from fair value.

 

A financial liability is derecognized when the obligation specified in the corresponding contract is paid or expired. When an existing financial liability has been replaced by another from the same lender, under substantially different terms, or the terms of an existing liability are substantially modified, such modification is treated as the de-recognition of the original liability and recognized as a new liability. The difference between the respective carrying amounts is recognized in the statement of profit or loss.

 

4.1.4 Derivative financial instruments and hedging activities

 

Financial derivative instruments are initially recognized in the statement of financial position as assets or liabilities and are measured at fair value on the date on which the derivative is recorded and subsequently measured at fair value. Changes in the fair value of derivatives are recognized as gains or losses in the statement of profit or loss, except for the effective portion of cash flow hedges, which is recognized in other comprehensive income and later reclassified to profit or loss when the hedge item affects profit or loss.

 

Changes in fair value of derivative contracts, which do not qualify or are not designated as hedges, including forward contracts for the purchase and sale of commodities under negotiation for physical delivery or receipt of the commodity are recorded in profit or loss.

 

Derivatives embedded in the host contract are accounted for as separate derivatives at fair value if their economic characteristics and risks are not closely related to those of the host contracts and the and the host contracts are not held for trading or designated at fair value through profit or loss. These embedded derivatives are measured at fair value with changes in fair value recognized in profit or loss.

 

4.1.5 Hedging operations

 

For purposes of hedge accounting, hedges are classified as:

 

§ Fair value hedges, when hedging the exposure to changes in fair value of a recognized asset or liability, or unrecognized firm commitment, or an identifiable portion of such asset, liability or firm commitment.

 

§ Cash flow hedges when hedging the exposure to variability in cash flows that is either attributable to a particular risk associated with a recognized asset or liability or a highly probable forecast transaction.

 

§ Hedges of a net investment in a foreign operation.

 

  F- 20  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

At the inception of the hedging relationship, the Group formally designates and documents the hedge relationship between the hedging instrument and the hedged item, together with its risk management objectives and strategy to perform hedging transactions. Such hedges are expected to be highly effective in achieving offsetting changes in fair value or cash flows and are; assessed on an ongoing basis to determine that they have been highly effective throughout the financial reporting periods for which they were designated.

 

4.1.5.1 Cash flow hedge

 

The effective portion of the gain or loss of the hedging instrument is recognized in other comprehensive income, while any ineffective portion is recognized in the consolidated statement of profit or loss, in the net financial results line item.

 

The amounts previously recognized in other comprehensive income are transferred to profit or loss, when the hedged transaction affects profit or loss. When the hedged item is the cost of a non-financial asset or liability, the amounts previously recognized in other comprehensive income are transferred to the initial carrying amount of the non-financial asset or liability.

 

If the hedging instrument expires or is sold, terminated or exercised without replacement or rollover, or if its designation as a hedge is revoked or when the hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss previously recognized in other comprehensive income remains separately in equity until the forecast transaction occurs is recognized in the consolidated statement of profit or loss. When it is no longer expected that the initially hedged transaction will occur.

 

Ecopetrol designates long-term loans as hedging instruments for its exposure to the exchange risk in future oil exports. See Note 30 for further information.

 

4.1.5.2 Hedge of net investment in a foreign operation

 

Hedges of net investment in a foreign operation are accounted in a way similar to the cash flow hedges.

 

Gains or losses on of the hedging instrument related to the effective portion of the hedge are recognized in other comprehensive income, while any gains or losses relating to the ineffective portion are recognized in the statement profit or loss. Cumulative gains or losses recorded in equity is transferred to the consolidated statement of profit or loss when the foreign operation is partially or totally disposed of.

 

Ecopetrol allocates long-term loans as hedging instruments for its exposure to foreign exchange risk on its investment in subsidiaries whose functional currency is the U.S. dollar. See Note 30 for further information.

 

4.2 Inventories

 

Inventories are stated at the lower of cost and net realizable value.

 

Inventories mainly comprise crude oil, fuels and petrochemicals and consumable inventories (spares and supplies).

 

The cost of crude oil is the production costs, including transportation costs.

 

The cost required to bring the pipeline into working order, is treated as part of the related pipeline.

 

  F- 21  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

The cost of other inventories is determined based on the weighted average cost method, which includes acquisition costs (deducting commercial discounts, rebates and other similar items), transformation, and other costs incurred to bring inventory to their current location and condition, such as transportation costs.

 

Consumable inventories (spares and supplies) are recognized as inventory and then charged to expense, maintenance or project to the extent that such items are consumed.

 

Ecopetrol estimates the net realizable value of inventories at the end of the period. When the circumstances that previously caused inventories to be written down below cost no longer exist, or when there is clear evidence of an increase in the net realizable value because of a change in economic circumstances, the amount of the write-down is reversed. The reversal cannot be greater than the amount of the original write-down, so that the new carrying amount will always be the lower of the cost and the revised net realizable value.

 

4.3 Related parties

 

Related parties are considered those in which one party has the ability to control, or has joint control of the other, or exercises significant influence over the other party in making financial or operational decisions, or is a member of key management personnel (or close relative of a member). The Group considers related parties to be associates, joint ventures, key management executives, entities managing resources for payment of employee post-employment benefit plans and Colombian government entities for the purposes of certain relevant transactions, such as the purchase of hydrocarbons and the fuel price stabilization fund (see Note 4.16) .

 

4.3.1 Investments in associates

 

An associate is an entity over which the Ecopetrol Business Group has significant influence but not control. Significant influence is the power to participate in the financial and operational policy decisions of the investee, but it is not control or joint control over those policies. Generally, these entities are those in which the Group holds an equity interest with voting rights of 20% to 50%. See Exhibit I - Consolidated companies, associates and joint ventures for further details.

 

Investments in associates are accounted for using the equity method. Under this method, the investment in an associate is initially recognized at cost. The carrying amount of the investment is adjusted to recognize changes in the Group’s share of net assets of the associate since the acquisition date. Goodwill related to the associate is included in the carrying amount of the investment and is not tested for impairment separately.

 

The Group's share of the results of operations of the associate is recognized in the consolidated statement of profit or loss. Any change in other comprehensive income is recognized in other comprehensive income of the Group.

 

After application of the equity method, the Group determines if it is necessary to recognize an impairment on its investment in its associate. At each reporting date, the Group determines whether there is objective evidence that the investment is impaired. If there is such evidence, the amount of the impairment is calculated as the difference between the recoverable amount and its carrying value, and then the impairment is recognized in the consolidated statement of profit or loss.

 

When necessary, the Group makes adjustments to the accounting policies of associates to ensure consistency with the policies adopted by the Group. Additionally, the equity method of these companies is measured on their most recent financial statements.

4.3.2 Joint ventures

 

A joint venture is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the joint arrangement. Joint control exists only when decisions about the relevant activities require unanimous consent of the parties sharing such control. The accounting treatment for the recognition of joint ventures is the same as investments in associates.

 

4.4 Joint operations

 

A joint operation is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the assets and obligations for the liabilities, relating to the arrangement.

 

Joint operation contracts are entered into between Ecopetrol and third parties to share risk, secure capital, maximize operating efficiency and optimize the recovery of reserves. In these joint operations, one party is designated as the operator to execute the operations and report to partners according to their participating interests. Likewise, each party takes its share of the produced hydrocarbons (crude oil or gas) according to their share in production.

 

When Ecopetrol participates as a non-operator partner, it records the assets, liabilities, sales revenues, cost of sales and expenses based on the operator’s report. When Ecopetrol is the direct operator of joint venture contracts, it records its percentage of assets, liabilities, sales revenues, costs and expenses, based on the participation of each partner in the items corresponding to assets, liabilities, sales revenues, costs and expenses.

 

When the Group acquires or increases its participation in a joint operation in which the activity constitutes a business combination, such transaction is recorded applying the acquisition method in accordance with IFRS 3 - Business combination. The acquisition cost is the sum of the consideration transferred, which corresponds to the fair value, on the date of acquisition of the assets transferred and the liabilities incurred. Any transaction cost related to the acquisition or increased share in the joint operation that constitutes a business combination is recognized in the consolidated statement of profit or loss.

 

The excess of the sum of the consideration transferred and the amount paid in the operation is recognized as goodwill. If the result is in an excess value of the net assets acquired over the amount paid in the operation, the difference is recognized as income in the consolidated statement of profit or loss on the date of recognition of the transaction.

 

4.5 Non-current assets held for sale

 

Non-current assets are classified as held for sale if their carrying values will be recovered principally through a sale transaction rather than through continued use. Non-current assets are classified as held for sale only when the sale is highly probable within one year from the classification date and the asset (or group of assets) is available for immediate sale in its present condition. These assets are measured at the lower of their carrying amount and fair value less related costs of disposal. See Note 13 for further information.

 

4.6 Property, plant and equipment

 

Recognition and measurement

 

Property, plant and equipment are stated at cost less accumulated depreciation and accumulated impairment losses. Tangible components related to natural and environmental resources are part of property, plant and equipment.

 

  F- 23  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

The initial cost of an assets comprises its purchase price or construction cost, including import duties and non-refundable purchase taxes, any costs directly attributable to bringing the asset into operation, costs of employee benefits arising directly from the construction or acquisition, borrowing costs incurred that are attributable to the acquisition and construction of qualifying assets and the initial estimate of the costs of dismantling and abandonment of the item.

 

Spare parts and servicing equipment are recorded as inventories and recognized as an expense as they are used. Major spare parts and stand-by equipment that the entity expects to use during more than one period are recognized as property, plant and equipment.

 

Any gain or loss arising from the disposal of a property, plant and equipment is recognized in profit or loss of the period.

 

Subsequent disbursements

 

Subsequent disbursements correspond to all payments to be made on existing assets in order to increase or extend the initial expected useful life, increase productivity or productive efficiency, allow for significant reduction of operating costs, increase the level of reserves in exploration or production areas or replace a part or component of an asset that is considered critical for the operation.

 

The costs of repair, conservation and maintenance of a day to day nature are expensed as incurred. However, disbursements related to major maintenance are capitalized.

 

Depreciation

 

Property, plant and equipment is depreciated using the straight-line method, except for those associated with exploration and production activities which are depreciated using the units-of-production method. Technical useful lives are updated annually considering factors such as: additions or improvements (due to parts replacement or critical components for the asset’s operation), technological advances, obsolescence and other factors; the effect of this change is recognized from the period in which it was executed. Depreciation of an asset starts when it is ready to be used.

 

Useful lives are determined based on the period over which an asset is expected to be available for use, physical exhaustion, technical or commercial obsolescence and legal limits or restrictions over the use of the asset.

 

The estimated useful life of assets fluctuates in the following ranges:

 

Plant and equipment 15 - 65 years
Pipelines, networks and lines 10 - 59 years
Buildings 12 - 80 years
Other 5 - 33 years

 

Land is recorded separately from buildings and facilities and is not subject to depreciation.

 

Depreciation methods and useful lives are reviewed annually and adjusted if appropriate.

 

  F- 24

4.7 Natural and environmental resources

 

Recognition and measurement

 

Ecopetrol uses the successful efforts method to account for exploration and production of crude oil and gas activities, following the provisions of IFRS 6 – Exploration for the evaluation of mineral resources.

 

Exploration costs

 

Acquisition and exploration costs are recorded as exploration and evaluation assets until the determination of whether the exploration drilling is successful or not; if determined to be unsuccessful, all costs incurred are recognized as expenses in the consolidated statement of profit or loss.

 

Exploration costs are those incurred with the objective of identifying areas that are considered to have prospects of containing oil and gas reserves, including geological and geophysical, seismic costs, viability, and others, which are recognized as expenses when incurred. Furthermore, disbursements associated with the drilling of exploratory wells and those related to stratigraphic wells of an exploratory nature are charged as assets until it is determined if they are commercially viable; otherwise, they are expensed in the consolidated statement of profit or loss as dry wells expense. Other expenditures are recognized as expenses when incurred.

 

An exploration and evaluation asset is no longer classified as such when the technical feasibility and commercial viability of extracting a mineral resource are demonstrable. Exploration and evaluation assets are reclassified to the natural and environmental resources account after being assessed for impairment.

 

All capitalized costs are subjected to technical and commercial revisions at least once a year to confirm the evaluation and exploration efforts continue on the fields; otherwise, these costs are written off through to profit or loss.

 

Exploration costs are net of the revenues obtained from the sale of crude oil during the extensive testing period, net of cost of sales, since they are considered necessary to complete the asset.

 

Development costs

 

Development costs correspond to those costs incurred to obtain access to proved reserves and to provide facilities for extracting, treating, gathering and storing. When a project is approved for development, the corresponding capitalized acquisition and exploration costs are classified as natural and environmental resources and costs subsequent to the exploration phase are capitalized as development costs of the properties that contain such natural resources. All development costs are capitalized, including drilling costs of unsuccessful development wells.

 

Production costs

 

Production costs are those incurred to operate and maintain productive wells, and are part of the corresponding equipment and facilities. Production activity includes extraction of oil and gas to the surface, its gathering, treatment and processing as well as storage in the field. Production costs are expenses recorded in the consolidated statement of profit or loss as incurred unless they add oil and gas reserves, in which case they are capitalized.

 

Production and support equipment is recognized at cost and is part of property, plant and equipment subject to depreciation.

 

  F- 25  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

Capitalized costs also include decommissioning, dismantling, retiring and restoration costs, as well as the estimated cost of future environmental obligations. The estimation includes plugging and abandonment costs, facility dismantling and environmental recovery of areas and wells. Changes arising in new abandonment liability estimations and environmental remediation are capitalized in the carrying amount of the related asset.

 

Depletion

 

Depletion of natural and environmental resources is determined using the unit-of-production method per field, using proved developed reserves as a base, except in limited exceptional cases that require greater judgment by Management to determine a better amortization factor of future economic benefits over the useful life of the asset. Depreciation rates are reviewed annually, based on reserves reports and the impact of any changes is recognized prospectively in the financial statements.

 

Reserves are audited by internationally recognized external consultants and approved by the Company’s Board of Directors. Proved reserves consist of the estimated quantities of crude oil and natural gas demonstrated with reasonable certainty by geological and engineering data to be recoverable in future years from known reserves under existing economic and operating conditions, that is, at the prices and costs that apply at the date of the estimation.

 

Impairment

 

Assets associated to exploration, evaluation and production are subject to review for possible impairment in their carrying amount. See notes 3.2 – Asset impairment (recovery) and 4.12 - Impairment of non-financial assets.

 

4.8 Capitalization of borrowing costs

 

Borrowing costs related to the acquisition, construction or production of a qualifying asset that requires a substantial period of time to get ready for its intended use are capitalized as part of the cost of such asset when it is probable that future economic benefits associated with the item will flow to the Group and costs can be measured reliably. Other borrowing costs are recognized as finance costs. Projects that have been suspended but that the Group intends to continue to pursue their development in the future, are not considered qualifying assets for the purpose of capitalization of borrowing costs.

 

4.9 Intangible assets

 

Intangible assets with a defined useful life, are stated at cost less accumulated amortization and any impairment loss. Intangible assets are amortized under the straight-line method, over their estimated useful lives. The estimated useful lives and amortization method are revised at the end of each reporting period; any change in estimates is recognized on a prospective basis.

 

The disbursements in relation to research activities are expensed as incurred.

 

4.10 Goodwill

 

Goodwill is initially measured at cost (being the excess of the aggregate of the consideration transferred and the amount recognized for non-controlling interest and any previous interest held over the net identifiable assets acquired and liabilities assumed). After initial recognition goodwill is measured at cost less any accumulated impairment loss. Goodwill is not amortized but tested for impairment annually.

 

  F- 26  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

4.11 Leases

 

Leases are classified as finance leases whenever the terms of the lease transfer substantially all the risks and rewards of ownership. All other leases are classified as operating leases.

 

Assets held under finance leases, when Ecopetrol is the lessee, are recognized in the consolidated statement of financial position at an amount equal to the fair value of the leased asset or, if lower, the present value of the minimum lease payment. These assets are depreciated over the asset's useful life. When there is no reasonable certainty that the company will obtain ownership of the asset at the end of the contract, the leased assets are depreciated in the shortest period between the asset estimated useful life and the lease term.

 

The corresponding liability to the lessor is included in the consolidated statement of financial position as a finance lease obligation, in the loans and financing line item.

 

Lease payments are apportioned between financial charges and reduction of lease liabilities in order to achieve a constant rate of interest on the liability remaining balance. Interest expense is recognized in profit or loss.

 

Operating lease payments are recognized as an expense on a straight-line basis over the lease term, except where another systematic prorating basis is more representative of the time pattern of economic benefits from the lease. Contingent rentals arising under operating leases are recognized as an expense in the period in which they are incurred.

 

4.12 Impairment of non-financial assets

 

In order to evaluate if any tangible or intangible assets are impaired, Ecopetrol compares its carrying amount with its recoverable amount at the end of each reporting period or earlier, if there is any indicator that an asset may be impaired.

 

For purposes of impairment testing, the assets are grouped into cash generating units (CGU), provided that those assets individually considered do not generate cash inflows that, to a greater extent, are independent from those generated by other assets or CGUs. The group of assets in different CGUs requires the exercise of professional judgment and the consideration, among other parameters, of the business segments. In this sense, in the Exploration and Production segment, each CGU corresponds to each one of the different contractual areas commonly called “fields”; by exception, in those cases where the cash inflows generated by several fields are interdependent from each other, those fields are grouped into a single CGU. In the case of the Refining and Petrochemicals segment, each CGUs corresponds to each one of the refineries of the Ecopetrol Business Group and for the Transportation segment; each pipeline is taken as an independent CGU.

 

The recoverable amount of the asset is the higher amount of the fair value less costs of disposal or its value in use. If the recoverable amount of an asset (or of a CGU) is lower than its net carrying amount, such amount (or that of the CGU) is reduced to its recoverable amount, recognizing an impairment loss in the statement of profit or loss.

 

Fair value less costs of disposal is usually higher than the value in use for the asset’s in the production segment due to some significant restrictions in the estimation of future cash flows, such as: a) future capital expenses that improve the CGU performance, which could result in expected increase of net cash flows, and b) items before taxes that reflect specific business risks, resulting in a higher discount rate.

 

Fair value less costs of disposal is determined as the sum of the future discounted cash flows adjusted to the estimated risk. The estimations of expected future cash flows used in the assessment of impairment of the assets include estimates of futures commodity prices, supply and demand estimations, and the margins of the products.

 

  F- 27  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

Fair value less costs of disposal, as described above, is compared to valuation multiples and quoted prices of shares in companies comparable to Ecopetrol, in order to determine if it is reasonable.

 

When an impairment loss is recorded, future amortization expenses are calculated on the basis of the adjusted recoverable amount. Impairment losses may be recovered only if the recovery is related to a change in estimations used after impairment loss was recognized. These recoveries do not exceed the carrying amount of the assets net of depreciation or amortization that would have been determined if such impairment had not been recognized.

 

The carrying amount of non-current assets reclassified as assets held-for-sale is compared to its fair value less costs of disposal. No other provision for depreciation, depletion or amortization is recorded if the fair value less costs of sale is lower than the carrying amount.

 

4.13 Provisions and contingent liabilities

 

Provisions are recognized when Ecopetrol has a current obligation (legal or implied) as a result of a past event, it is probable that Ecopetrol will be required to settle the obligation, and a reliable estimation can be made of the amount of the obligation. Where applicable, they are recorded at present value, using a rate reflecting the liability specific risk.

 

Future environmental decommissioning costs related to current or future operations, are accounted for as expenses or assets, as the case may be. Expenditures related to past operations that do not contribute to the obtaining of current or future benefits, are expensed as incurred.

 

The recognition of these provisions coincides with the identification of an obligation related to environmental remediation and Ecopetrol uses available information to determine a reasonable estimation of the related cost.

 

Provisions for which a negative outcome is assessed as possible are not recognized but are disclosed in the explanatory notes; including those for which the amount cannot be estimated.

 

If there is an expectation that the provision will be reimbursed, either in whole or in part, for example by virtue of an insurance contract, the amounts expected to be reimbursed are recognized as a separate asset only when such reimbursement is almost certain.

 

If the effect of the time value of money is significant, the provisions are discounted using the current market rate before taxes reflecting, as applicable, the liability specific risks. When recognizing the discount, the increase of the provision resulting from time elapsed is recognized as financial cost in the profit or loss statement.

 

Asset retirement obligation

 

Liabilities associated with the retirement of assets are recognized when there are current obligations, either legal or implied, related to the abandonment and dismantling of wells, facilities, pipelines, buildings and equipment.

 

The obligation is usually recorded when the assets are installed or the surface or the environment are altered at the operating sites. These liabilities are calculated using the discounted cash flow method, using a pre-tax rate reflecting current market conditions similar liabilities and considering the economic limits of the field or the useful life of the respective asset. When it is not possible to determine a reliable estimation in the period in which the obligation originates, a provision is recognized when there is sufficient information available to make the best estimation.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

The carrying amount of the provision is reviewed and adjusted annually considering changes in the assumptions used for its estimation, using a rate that reflects the liability specific risk. Any change in the present value of the estimated expenditure is reflected as an adjustment to the provision and the corresponding property, plant and equipment and natural and environmental resources. When a decrease in the asset retirement obligation related to a producing asset exceeds the carrying amount of the asset, the excess is recognized the consolidated statement of profit or loss. The financial cost of updating these liabilities is recognized in results for the period as financial expense.

 

4.14 Income tax and other taxes

 

Income tax expense is comprised of income tax payable for the period (including, income tax and income tax for equality - CREE, as appropriate) and the effect of deferred taxes in each period.

 

Current income taxes are recognized in income except when they relate to items recognized in other comprehensive income, in which case the corresponding tax effect is also recognized in other comprehensive income. Income tax assets and liabilities are presented separately in the consolidated statement of financial position except where there is a right of set-off within fiscal jurisdictions and an intention to settle such balances on a net basis.

 

4.14.1 Current income tax

 

The Group determines the provision for income tax based on the highest amount between taxable income and presumptive income (the minimum estimated amount of taxable profit on which the law expects to quantify and collect income taxes). Taxable income differs from profit before tax as reported in the consolidated statement of profit or loss, because of: items of income or expense that are taxable or deductible in other periods, special taxable deductions, tax losses and income and line items measured that, according to applicable tax laws in each jurisdiction, are considered nontaxable or nondeductible.

 

4.14.2 Deferred income tax

 

Deferred tax is provided using the liability method for temporary differences between the carrying amounts of existing assets and liabilities in the consolidated financial statements and their respective tax bases. A deferred tax liability is recognized for all taxable temporary differences. A deferred tax asset is recognized for all deductible temporary differences and for all accumulated tax losses, if there is a reasonable expectation that the Group will generate future tax profits against which they will be used.

 

Deferred taxes on assets and liabilities are calculated based on the tax rates that are expected to apply during the years in which temporary differences between the carrying amounts and tax bases are expected to be reversed.

 

The carrying amount of a deferred tax asset is subject to review at the end of each reporting period and it is reduced to the extent it is no longer probable that there Group will generate enough future taxable profit to realize such deferred tax asset.

 

In the statement of financial position, deferred tax assets are reflected net and as an offset against deferred tax liabilities, depending on the overall tax position in a particular jurisdiction and on the same taxable entity.

 

Deferred taxes are not recognized when they arise in the initial recognition of an asset or liability in a transaction (except in a business combination) and at the time of the transaction, does not affect the accounting or tax profit, or in respect of the taxes on the possible future distribution of accumulated profits of subsidiaries or investments accounted for by the equity method, if at the time of the distribution it may be controlled by Ecopetrol and it is probable that the retained earnings will be reinvested by the Group companies and, therefore, will not be distributed to Ecopetrol.

4.14.3 Other taxes

 

The Group recognizes in profit or loss the costs and expenses related to other taxes than the income tax, such as the wealth tax, which is determined based on the tax equity, the industry and commerce tax on income obtained in the municipalities for performance of commercial, industrial and service activities, and the transport tax on volumes loaded in the transport systems. Taxes are calculated in accordance with current tax regulations. For more details, see Note 10.

 

4.15 Employee benefits

 

Salaries and benefits for Ecopetrol staff are governed by the Colombian Collective Labor (Agreement 01 of 1977), and, by the Colombian Substantive Labor Code. In addition to the legally mandated benefits, employees are entitled to fringe benefits which are subject to the place of work, type of work, length of service, and basic salary. An annual interest of 12% is recognized on accumulated severance amounts for each employee, and the payment of compensation is provided for when special circumstances arise resulting in the non-voluntary termination of the contract, without justified cause, and in periods other than the probationary period.

 

Ecopetrol belonged to the special pension regime under which pension liabilities are Ecopetrol’s responsibility and not pension fund’s responsibility. However, Law 797 of January 29, 2003 and Legislative Act 001 of 2005 determined that Ecopetrol will no longer belong to the said regime and that from that point on employees would be part of the General Pension Regime. Consequently, pension obligations related to employees pensioned until July 31, 2010 are still Ecopetrol’s responsibility. Employees are entitled to such pension bonus if they worked with Ecopetrol prior to January 29, 2003, but whose labor agreement expired without renewal before that date.

 

All labor benefits of employees who joined Ecopetrol before 1990 are Ecopetrol’s responsibility, without the involvement of any social security entity or institution. Service cost for the employee and his/her relatives registered with the Group is determined by means of a mortality table, prepared based on facts occurring during the year.

 

For employees who joined Ecopetrol after the Act 50 of 1990 went in effect, Ecopetrol makes periodic contributions for severance payments, pensions and labor risks to the respective funds.

 

In 2008, Ecopetrol partially commuted the value corresponding to monthly pension payments from its pension liabilities, transferring such liabilities and their underlying amounts to autonomous pension funds (PAP, for its acronym in Spanish). The funds transferred, and returns on those funds, cannot be redirected nor they can be returned to the Group until all of the pension obligations have been fulfilled. The commuted obligation covers allowances and pension bonds payments; while health and education remains under the labor liability in charge of Ecopetrol.

 

Employee-benefits are divided into four groups comprised as follows:

 

a) Short-term employee benefits and post-employment defined benefits:

 

Benefits to employees in the short term mainly correspond to those which payment will be made in the term of twelve months following the closing of the period in which the employees have rendered their services. These mainly include salaries, severance payments, vacation, bonuses and other benefits.

 

  F- 30  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

Post-employment benefits of defined contributions correspond to the periodic payments for severance, pensions and labor risk payments that the Group makes to the respective funds that assume these obligations in their entirety.

 

The above benefits are recognized as an expense with an associated liability after deducting any already paid amounts.

 

b) Post-employment defined benefit plans:

 

In the defined benefits plan, the Group provides the benefits agreed to current and former employees and assumes the actuarial and investment risks.

 

The following benefits are classified as long-term defined benefit plans recognized in the financial statements according to the calculations of an independent actuary:

 

§ Pensions
§ Pension bonds
§ Health
§ Educational plan
§ Retroactive severances

 

Liabilities recognized in the statement of financial position in respect of these benefit plans are the present value of the defined benefit obligation at the date of the statement of financial position, less the fair value of plan assets.

 

The defined benefit obligation is calculated annually by independent actuaries using the projected credit unit method, which takes into account employees’ years of service and, for pensions, average or final pensionable remuneration. This obligation is discounted at its present value using interest rates of high-quality government bonds denominated in the currency in which the benefits will be paid and of a duration consistent with the plan obligations.

 

These actuarial calculations involve several assumptions that could differ from the events that will effectively take place in the future. Said assumptions include the determination of the discount rate, future salary increases, mortality rates and future pension increase. Because of the complexity of the calculation, the underlying assumptions and long-term nature of these plans, the obligations for defined benefits are extremely sensitive to changes in assumptions. All key assumptions are revised at the end of the reported period.

 

In determining the appropriate discount rate, in absence of a broad high quality bond market, Management considers interest rates corresponding to the class B TES bonds issued by the Colombian Government as its best reference, at an appropriate discount rate with maturities extrapolated in line with the term expected for each benefit plan. The mortality rate is based on the particular country’s rate, which latest version is the RV08 mortality table published in resolution 1555 of October 2010. The future salary and pension increases are linked to the country's future inflation rates. Note 22 - Provisions for employee benefits provides further details on key assumptions used.

 

The amounts recognized in the consolidated statement of profit or loss related to employees defined benefit plans are comprised mainly by service cost and the net financial expense. Service cost includes mainly the increase in present value of the benefit obligation during the period (current service cost) and the amount resulting from a new benefit plan. Plan amendments corresponds to changes in benefits and are usually recognized when all legal and regulatory approvals have been obtained and the effects have been conveyed to the employees involved. The net financial expense is calculated using the net liability for defined benefits as compared with the yield curve of the discount rate at the beginning of each year for each plan. The net defined benefit liability or asset resulting from actuarial profits and losses, the asset ceiling effect and the asset profitability, excluding the value of recognized in the consolidated statement of profit or loss, are recognized in other comprehensive income.

 

  F- 31  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

When the plan assets exceed the gross obligation, the recognized asset is limited to the lower of the surplus in the defined benefits plan and the ceiling of assets determined using a discount rate based on Colombian Government bonds.

 

(a) Other long term benefits

 

Other long-term benefit is the five-year term bonus which also considered in the actuarial calculation. This benefit is a cash bond that accumulates annually and is paid every five years to employees. The Group recognizes in the consolidated statement of profit or loss the service cost, the net financial cost and the adjustment to the obligation of the defined benefit plan.

 

(b) Termination benefits

 

Termination benefits are recognized only when a detailed plan exists for such process and there is no possibility to withdraw the offer. The Group recognizes a liability and an expense for termination benefits at the earliest date between the date when the offer of such benefits cannot be withdrawn and the date when the restructuring costs are recognized.

 

4.16 Sales revenue recognition

 

Sales revenue from crude oil and natural gas sales is recognized at the time of transfer of title to the buyer, including risks and rewards of ownership. In the case of refined and petrochemical products, sales revenue is recognized when products are shipped by the refinery and subsequently adjusted in accordance with price changes when dealing with regulated price products, as explained bellow. Sales revenue from transportation services is recognized when products are transported and delivered to the buyer in accordance with contractual terms. In all other cases, sales revenue is recognized at the time it is earned and a true, probable and quantifiable right to demand its payment arises.

 

Under current regulations, Ecopetrol and Refinería de Cartagena S.A. sell regular gasoline and mid-distillates at a regulated price.

 

In accordance with Decree 1068 of 2015, the Ministry of Mines and Energy calculates semiannually and settles Ecopetrol’s net position to be stabilized for each fuel by the Fuel Price Stabilization Fund (FEPC, for its acronym in Spanish). The amount to be settled is calculated as the volume sold during the corresponding period multiplied by the difference between the international parity price and the reference price actually charged. The net position is calculated by adding all differentials throughout the six month period in Colombian pesos in favor of the Group and chargeable to the FEPC. The international parity price is the daily price of gasoline and diesel oil of the respective month in Colombian pesos, indexed to the United States of America Gulf market price, calculated in accordance with Resolution 18 0522 of 2010. The reference price is the price per gallon fixed by the Ministry of Energy and Mines, at which refiners or importers sell gasoline or diesel to the national market. Therefore, this difference represents a higher or lower value of sales revenues for Ecopetrol S.A. and Refinería de Cartagena S.A.

 

4.17 Costs and expenses

 

Costs and expenses are presented according to their nature; they are detailed in the related disclosures in cost of sales, and administrative, operating, projects and other associated expenses.

4.18 Finance income (expenses)

 

Finance income and expenses include mainly: a) borrowings costs on loans and financing, except for those that are capitalized on qualifying asset, b) gains and losses on changes in fair value of financial instruments measured at fair value through profit or loss, c) currency exchange differences of financial assets and liabilities, except for debt instruments designated as hedging instruments, d) interest expenses as a result of discounting long-term liabilities (abandonment costs and pension liabilities), e) dividends derived from equity instruments measured at fair value with changes in other comprehensive income.

 

4.19 Information by business segment

 

Ecopetrol presents the respective disclosures relative to its business segments in its consolidated financial statements in accordance with paragraph 4 of IFRS 8 - Operation segments.

 

The operation of the Ecopetrol Business Group is performed through three business segments: 1) Exploration and Production, 2) Transport and Logistics, and 3) Refining, Petrochemical and Biofuels. This segmentation is based on management of objectives and corporate strategic plan, considering that these businesses: (a) are engaged in differential commercial activities, which generate sales revenue and incur costs and expenses; (b) the operational results are revised regularly by the Group's Governance that makes operational decisions to allocate resources to the various segments and assess their performance; and (c) there is differentiated financial information available. Internal transfers represent sales to inter-company segments and are registered and presented at market prices.

 

a) Exploration and production : This segment includes activities related to the exploration and production of oil and gas. Sales revenues are derived from sales of oil and natural gas at market prices to other segments and to third parties (domestic and foreign distributors). Costs include costs incurred in production. Expenses include all exploration costs that are not capitalized.

 

b) Transport and Logistics: This segment includes sales revenue and costs associated with the transport and distribution of hydrocarbons, derivatives and products operation.

 

c) Refining and Petrochemicals: This segment mainly includes activities performed at the Barrancabermeja and Cartagena refineries, where crude from production fields is transformed. The sales revenue from products are realized to other segments and domestic and foreign customers and include refined and petrochemical products at market prices and some fuels at regulated price. This segment also includes industrial service sales to customers.

5. New accounting standards and regulatory changes

  

Ecopetrol adopted for the first time the following amendments to the IFRS issued by the IASB, applicable for the period covered by this report:

 

§ Amendments to IAS 7 statement of cash flows - Disclosure initiative: requires entities to disclose changes in their liabilities arising from financing activities, including those arising from cash and non-cash flows (including, among others, the effect of fluctuations in the Colombian peso-U.S. dollar exchange rate). The adoption of the amendments to IAS 7 had no impact on the amounts recognized in the financial statements. The Group provides the information for the current period and the comparative period, required by this standard in Note 20 - Loans and borrowings.

 

The following accounting standards will become effective in future periods and are being implemented and /or assessed:

 

§ IFRS 9 "Financial instruments" replaced IAS 39 "Financial Instruments: Recognition and Measurement" and entered into force for annual periods beginning on January 1, 2018. IFRS 9 includes standards on: 1) the classification and measurement of financial assets and liabilities, 2) impairment of financial assets, and 3) hedge accounting. Ecopetrol will apply these standards on their effective date.

 

In relation to classification and measurement, the Group made and assessment on its financial assets and liabilities and concluded that: a) the valuation of financial assets and liabilities measured at amortized cost is consistent with the Group’s business model, which seeks to pay or receive cash flows at a certain moment; b) the amortized cost valuation method does not apply to short-term accounts payable and receivables, as they do not have an associated interest rate and their settlement is less than one year; and c) investment portfolios and financial derivatives continue to be measured at fair value with changes in fair value through profit or loss, in compliance with their function within the Group’s business model.

 

Based on the aforementioned evaluations, the current classification of the Group's financial instruments is consistent with its business model and no significant change to the current accounting is expected.

 

With respect to the impairment assessment model applied to financial assets valued at amortized cost, Management believes that the adoption of IFRS 9 will not result in any impact, taking into account processes executed to monitor credit risk, knowledge prior to the financial situation of the counterparties with which transactions are made, and the quality of the portfolio.

 

Finally, with respect to the hedging accounting model, as an accounting policy, the Group decided to continue applying the guidance of IAS 39 for existing operations. Should Ecopetrol decide to establish new hedges, the requirements of IFRS 9 will be assessed to establish the relationship of those hedges to and their alignment with risk management objectives, as well as the qualitative and quantitative components to be considered for effectiveness of the assessment.

 

§ IFRS 15 "Revenue from ordinary activities in contracts with customers" provides a five-step model to account revenue arising from contracts with customers, focusing on the identification and fulfillment of performance obligations. IFRS 15 replaces IAS 18 "Revenue" and is effective for annual periods beginning on or after January 1, 2018. According to the new standard, revenues are recognized when performance obligations are satisfied and there is no indication that the price or variable consideration are not measurable or realizable. Likewise, the recognition of revenue is observed when the client obtains control of the goods or services offered in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. The standard also contains presentation and disclosure requirements that are more detailed than those defined by IAS 18, which represents an increase in the volume of disclosures required in the financial statements.

 

  F- 34  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

The Ecopetrol Business Group will apply this standard on January 1, 2018, using the modified retrospective method, which allows adjusting the calculated impacts within equity, at the date of initial application, without adjusting the comparative years. Management estimates that the adoption of the new standard will not have a material effect; nevertheless, the adoption will required the implementation of new internal controls, changes in accounting procedures and policies to allow documentation on the adoption of the standard and its future application.

 

During the process of implementing IFRS 15, sources of ordinary income were assessed, considering the identification of contracts with customers, performance obligations, the determination of transaction prices, the association of prices with performance obligations, and the recognition of income when such obligations are fulfilled. The analysis included the following aspects by segment:

 

Exploration and production : Revenues in this segment correspond to the sale of oil and natural gas. The Group assessed the following: agreements with partners in joint operations, long-term contracts, over and underlifting, production, royalties, role of principal and agent, purchase and sale agreements, take-or-pay agreements and variable price components. No significant impacts were identified for the recognition, measurement or presentation of revenue in this segment.

 

The Group assessed whether the operating partner in a joint operation can have a contract with another non-operator partner to market and sell the non-operator product to a third party. The analysis included whether one of the parties acts as principal or agent in the agreement. The operator evaluates whether it records gross income based on total production or net income based on its net operating interest. The non-operator evaluates the moment of revenue recognition. The Ecopetrol Business Group does not maintain significant agreements with non-operating partners whereby it assumes the role of agent.

 

Transport and Logistics : Revenues in this segment correspond to the income from transport, storage and wholesale commercialization of crude or refined products derived from petroleum either by pipeline, rail, barge or truck. Pipelines and other transportation systems can be used to move crude oil from production sites to refineries and deliver the various refined products to fuel distributors. The main aspects evaluated are ship or pay and ship and pay contracts, variable price components and deposit agreements. The Ecopetrol Business Group has evaluated the performance obligations established in the provision of service, noting that there are no conditions with effects on the variable price related to volumetric adjustments or other contractual conditions that prevent recognition of income.

 

Take-or-pay contracts : Commodity sales contracts and some firm storage and transportation contracts can be structured as more complex purchase or minimum payment contracts, which specify minimum quantities of product that a customer will pay, even if they choose not to receive or use them. The quantities of products that a customer chooses not to take or use in the specified delivery period are called "deficient quantities."

 

No significant impacts were identified for recognition, measurement or reporting of revenue for this segment.

 

  F- 35  

 

 

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

Refining, Petrochemicals and Biofuels : Revenues in these segments correspond to the refining of oil, the processing and purification of natural gas, and the production of petrochemicals and biofuels. The main aspects assessed are long-term contracts, variable price components, non-monetary agreements, discounts, financing components and refinery network deliveries. No significant impacts were identified for the recognition, measurement or reporting of revenue for this segment.

 

For each of these segments, income is recognized when the goods or services have been delivered to customers at the established delivery points (when the performance obligation is fulfilled), whereby the transfer of the goods takes place and the risks associated with the products have been accepted by customers.

 

Regarding the agent and principal structure, as part of the process of selling products or services, the Ecopetrol Business Group enters into contracts to acquire, on behalf of the customer, other products or provide services. Under these contracts, the Ecopetrol Business Group is considered as the entity responsible for fulfilling the specific performance obligation. In some cases an inventory risk is not maintained before or after having sold the good or rendered the service. The Ecopetrol Business Group has assessed the impact on recognition in both cases and does not expect significant effects in the adoption of the new standard.

 

As a result of the analysis of these segments, it was concluded that: a) for contracts with several performance obligations, the Group concluded that such contracts are interdependent; therefore, the prices assigned are not independent and the application of a pricing methodology was not required; b) the Ecopetrol Business Group acts as principal in its transactions where it controls assets before transferring them to a client; c) the Group recognizes variable considerations in transaction prices unless they cannot be reliably measured, in which case the recognition is deferred until the uncertainty is resolved; d) the product's method is used by the Group to recognize income from long-term contracts with partial deliveries of goods; e) no effects associated with contract costs were identified when they were recognized in the accounting period and capitalization of the costs is not required; and, f) non-monetary agreements are recognized at fair value.

 

§ IFRS 16 "Leases" provides a new model for a lessee's accounting, according to which all leases, other than those of short-term and with small amounts, will be recognized in the balance sheet, as an asset (right of use) and a liability (financial lease) and in the statement of profit or loss, the respective amortization of the right of use during the term of the lease. IFRS 16 will be effective for annual periods beginning on or after January 1, 2019, with limited possibilities for early implementation. IFRS 16 replaces the current IAS 17 "Leases" and IFRIC 4 "Determination of whether an agreement contains a lease".

 

IFRS 16 "Leases" contains a new model for the identification of leases and their treatment in the financial statements for lessees. As a result of its implementation, oil and gas companies could recognize more assets and liabilities, mainly derived from the rental of drilling equipment and offices.

 

Ecopetrol has completed its initial assessment and started an action plan for its implementation. The Group will continue to perform a more detailed analysis of the potential impact on the financial statements from the adoption of IFRS 16 and does not expect to adopt it in advance.

§ Amendments to IFRS 10 and IAS 28: Asset sale or contribution between an investor and its associate or joint venture.

 

The amendments address the conflict between IFRS 10 and IAS 28 as to the treatment of control loss of a subsidiary that is sold or contributed to an associate or joint venture. The amendments clarify that the gain or loss resulting from the asset sale or contribution that constitutes a business, as defined in IFRS 3, between the investor and its associate or joint venture, is recognized in its entirety. However, any gain or loss resulting from an asset sale or contribution that is not a business, is recognized only up to the interests of investors who are not related to the associate or joint venture. The IASB has deferred the effective date of these amendments indefinitely, but an entity that early adopts it must apply them prospectively.

 

§ Annual Improvements to IFRS Standards 2014-2016 cycle: Modifications to the following standards:

 

- IFRS 12: The interpretation clarifies the scope of the standard by specifying that disclosure requirements in the standard, except those listed in paragraphs B10 to B16, apply to the interests of an entity listed in paragraph 5 (subsidiaries, joint arrangements, associates and non-consolidated structured entities), which are classified as held for sale or discontinued operations in accordance with IFRS 5.

 

- IFRIC 22 Transactions in foreign currency and early consideration: The interpretation deals with transactions in foreign currency where:

 

§ There is a consideration that is denominated in foreign currency;
§ The entity recognizes an asset for early payment or a deferred tax liability with respect to such consideration, before the recognition of the related asset, expense or income; and
§ The asset for said advance or deferred tax liability is not monetary.

 

The Interpretations Committee reached the following conclusions:

 

§ The date of the transaction, in order to determine the exchange rate, is the date of the initial recognition of the non-monetary advance or deferred tax liability.
§ If there are several payments received in advance, a transaction date is established for each payment.

 

These new accounting policies are subject to change until the Group presents its first financial statements on the initial application date.

Other taxes (3)     512,588       328,244  
Total     2,005,688       2,130,940  

 

(1) Corresponds to the resulting value after subtracting advanced tax payments, favorable balances and advance payments settled in the previous year's statement. The main variation compared to the previous period corresponds to the decrease in non-deductible expenses, and the effects of the tax reform on issues such as depreciation and exchange difference.

 

(2) Includes mainly the value added tax (VAT) receivable balance.

 

(3) Mainly includes VAT payable balances and industry and commerce tax.

 

10.2 Income tax

 

In accordance with Law 1819/2016 (Tax Reform), the tax regulation applicable in Colombia for the 2017 taxable year and subsequent years is as follows:

 

a) The income tax rate will be 34% for the taxable year 2017 and 33% for the taxable year 2018 and subsequently.

 

b) A surtax was established on income tax for 2017 and 2018, of 6% and 4%, respectively, which is applicable when taxable income exceeds COP$800 million.

 

c) Companies located in a free trade zone are taxed at a rate of 20%. If the Group located in a free trade zone has a Legal Stability Contract (hereinafter CEJ, for its acronym in Spanish), the income tax rate will continue to be 15% during the term of the said contract. This applies to Reficar, Bioenergy Zona Franca and Comai.

 

d) Presumptive income will be calculated by applying a 3.5% rate to the liquid equity balance of the immediately preceding year. For entities that have a CEJ, the stabilized rate for the calculation of presumptive income will continue to 3%, during the term of the contract.

 

e) For fiscal year 2017, the Ecopetrol Business Group has companies that are subject to a 40% income tax rate, companies in Free Trade Zones that are subject to a 15% income tax rate (which have CEJ) and 20% income tax rate, and other entities that are subject to statutory income tax rates in the country where they are incorporated.

f) Aligns the tax depreciation systems to accounting depreciation and establishes a limit to the annual depreciation deductible amount based on the table established in the tax reform. Tax amortization of oil and gas investments is calculated based on the technical production unit method which is aligned with accounting amortization.

 

g) The cost of acquisition of exploration rights, G & G, exploratory drilling, etc., is capitalized for tax purposes until the technical and commercial feasibility of extracting the resource is achieved.

 

h) Accumulated tax loss balance generated starting January 1, 2017 can be offset with the liquid income generated over the following 12 years (unlimited for those with CEJ).

 

i) For the period January 1, 2013 through December 31, 2016, taxable income in Colombia was subject to a 25% income tax rate with an additional 9% related to the income tax for equality "CREE", excluding tax payers who, based on an express provision manage special rates, and 10% rate on income from occasional profits; 15% income tax rate for companies in the free trade zone pay, and those not generating net income or whose net taxable income or with net taxable income lower than the presumptive income at 3% rate on equity.

 

On December 23, 2014, through Law 1739, a surtax on income for equality - CREE was established for the years 2015, 2016, 2017 and 2018, which is applicable entities with taxable income above COP$800 million, at rates of 5%, 6%, 8% and 9% per year, respectively.

 

For taxable year 2016, the Ecopetrol Business Group had companies subject to a 40% income tax rate, companies in free trade zones subject to a 15% and 20% income tax rate, and other entities that were subject to statutory income tax rates in the country where they are incorporated, and some other entities that pay taxes under presumptive taxable income in Colombia.

 

j) As of December 31, 2017 and 2016, Refinería de Cartagena, Bioenergy, and Ecopetrol Costa Afuera S.A.S., subsidiaries, have accrued accumulated tax losses that can be offset with future taxable income of COP$4,288,957 and COP$ 3,352,216, respectively, originated between 2009 and 2017. As per current tax legislation, accumulated tax losses accrued starting fiscal year 2007 can be offset, or tax adjusted, at any time, against taxable income without prejudice of the periods in which the entity was subject to the presumptive income regime. Accumulated tax losses cannot be transferred to its shareholders. However, in accordance with Article 290 of Law 1819 of 2016, the unused accumulated tax losses through December 31, 2016, can be offset based on a formula contained in that article.

 

As of December 31, 2017, deferred tax assets related to unused accumulated tax losses, which do not expire, amounted to COP$611,766 attributable to the Refinería de Cartagena. Such deferred tax assets were calculated based on COP$4,078,439 of accumulated income tax losses. The recognition of this deferred tax is based on the refinery's operational stability of the refinery presented in 2017, the projection of margins and the optimization of costs.

 

The assessment of the accumulated tax losses related to companies Ecopetrol Costa Afuera S.A.S., Bioenergy and Bioenergy Zona Franca with respect to deferred tax is mentioned in this note under the chapter titled "Deferred Income Tax".

 

In accordance with Article 290 of Law 1819 of 2016, the unused presumptive income surplus and minimal base surplus generated before 2017 on income tax and CREE can be used based on a formula contained in said Article and subject to the terms established in Article 189 of the Tax Code.

Statute of limitations of review for tax returns

 

Tax returns may be reviewed by the tax authorities within 5 years following the filing date and/or amendment, if the returns reflected tax losses.

 

As of the year 2017, the statute of limitations covering tax returns will be 3 years as of the date of expiration or as of the filing date, when these have been filed extemporaneously. With respect to transfer pricing, the statute of limitations will be 6 years.

 

With respect to tax returns with favorable balances, the statute of limitations will be 3 years as of the filing date of the request for devolution or offsetting.

 

With regard to tax returns in which tax losses are offset, these will be considered determined after 6 years counted as of their filing date. With respect to tax returns where tax losses are calculated, the statute of limitations will be 12 years and if the losses are offset within the last 2 years of the 12-year period, the statute of limitations will be extended up to 3 additional years from the year of offsetting.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

The effective tax rate (ETR) as of December 31, 2017 was 42.1% (2016 - 58.3%). The decrease compared to the previous year is mainly due to the following: a) Decrease in non-deductible expenses due to the effects of the transportation tax; b) Adjustment for differential of taxable bases; c) The adjustment for differential tax rates of the Group other than the nominal 40%, where the most significant item is the deferred tax asset to be amortized in the long term, with a rate lower than the nominal rate; and d) The adjustment of the wealth tax due to the effect of the rate, which is 0.4% for 2017, compared to 1% in 2016.

 

Income and supplementary tax returns for taxable years 2011, 2012, 2014, 2015 and 2016, and CREE returns for taxable years 2014, 2015 and 2016 of the Ecopetrol Business Group are subject to acceptance and review by the tax authorities. Management of the Ecopetrol Business Group companies considers that the amounts accounted as liability for payable taxes are sufficient and are supported by current regulations, doctrine and case law applicable to any claim that could be eventually filed with respect to such years. The Group's strategy is not making tax decisions based on aggressive or less-assured positions that could put into question its tax returns.

The table above takes into consideration the offsetting of deferred tax assets and deferred tax liabilities within the same tax jurisdiction. The overall deferred tax position in a particular tax jurisdiction determines if a deferred tax balance is presented within deferred tax assets or deferred tax liabilities. Accordingly, certain deferred tax assets are presented within deferred tax liabilities, and certain deferred tax liabilities within deferred tax assets.

The Ecopetrol Business Group offsets assets and liabilities for deferred taxes only if it has a legally enforceable right to offset current tax liabilities and assets; and in the case of deferred tax on assets and liabilities, to the extent that they also correspond to income taxes required by the same tax jurisdiction and the same tax authority.

 

Pursuant to current tax law, losses generated in income and supplementary taxes and/or income tax for equality - CREE before 2017, must be offset with the net income obtained in 2017 and subsequent periods, taking into account the formula set forth in Section 5, Article 290 of Law 1819 of 2016. Tax losses determined must not be tax readjusted.

 

As of the tax year 2017, companies can offset tax losses obtained in the current period defined, with taxable income generated through the next 12 taxable periods, following the attainment of said tax losses, without prejudice of the period's presumptive income.

 

Deferred tax assets related to tax losses generated by Bioenergy S.A. and Bioenergy Zona Franca in the amount of COP$(53,328), and excess presumptive income of Refinería de Cartagena in the amount of COP$(44,475) were written off in 2016 because, even though they can be offset in the long term, Management concluded that having a conservative position, it is not likely that the deferred tax assets related to such tax losses and excess of presumptive income would be recoverable in the short term.

 

If the Group would have recognized the deferred tax assets that were not recognized, the income for the period ended on December 31, 2017, would have increased by COP$ 97,803.

Deferred tax assets (liabilities) not recognized

10.3 Other taxes

 

10.3.1 Tax on dividends

 

The new tax on dividends will be applicable to foreign companies and entities on profits generated starting 2017.

 

The rate of this tax will be 5%. Furthermore, the tax rate for dividends will be 35%. In this scenario, the 5% tax on dividends will apply to the amount of the tax distribution, once it has been reduced with the 35% income tax.

 

For taxed individuals residing in Colombia, the tax on dividends will have a maximum 10% rate that will be applied on non-taxed dividends, and 35% with respect to taxed dividends distributed.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

There are no effects on income tax related to dividend payments made by the Group to its shareholders during 2017 and 2016.

 

10.3.2 Transfer prices

 

Income tax payers carrying out operations with related parties abroad or located in free trade zones or companies located in countries considered tax havens, must determine their ordinary and extraordinary revenues, costs and deductions, considering the arm's length principle for such transactions.

 

Such companies submitted their transfer-pricing information statement for the 2016 tax year and their respective supporting documents.

 

For the 2017 tax year, the transactions performed with related parties abroad, as well as the business conditions for such operations and their general structure, did not vary significantly as compared with the previous year. Therefore, it can be inferred that said transactions were performed in accordance with the arm's length principle. It is estimated that no adjustments will be required from the analysis of transfer prices in 2017, which entail amendments of the income provision of taxable year 2017.

 

10.3.3 Value added tax (VAT)

 

As of tax year 2017, the general sales tax rate is 19%, with a differential 5% rate for some goods and services is maintained in accordance with Articles 184 and 185 of Law 1819 of 2016.

 

As of tax year 2017, the VAT was extended to the sale of goods at large, the sale or concession of intangibles related to industrial property and to the provision of services in Colombia, or from services abroad, except for express exclusions of the norm, pursuant to Article 173 of Law 1819 of 2016.

 

Likewise, Article 194 of this Law stipulated that the term for filing requests for VAT deductions will be 3 bimonthly periods immediately following the period of causation.

 

10.3.4 Wealth tax

 

Law 1739 of 2014 established the wealth tax for natural and juridical persons whose possession of wealth at January 1, 2015 exceeds COP$1,000 million. The taxable base for companies is the gross equity value held as of January 1, 2015, 2016 and 2017, less the debts valid on the same dates.

 

The applicable rate will depend on the taxable base of each taxpayer and the paid value will not be deductible or discountable on income and supplementary taxes or income tax for equality - CREE, nor can they be offset by these, or any other taxes.

 

In 2017, the wealth tax paid by the Group amounted to COP$226,778, which was recognized as an expense in the period (2016 - COP$569,756).

14.2 Restrictions on investments

 

The number of shares held by Ecopetrol in Invercolsa S.A. has been subject to a legal dispute with another shareholder of this company. The courts decided in favor of Ecopetrol through a ruling IN 2011, whereby it was determined that 324 million shares, equivalent to 11.58% of Invercolsa S.A.’s share capital should be returned to Ecopetrol. Ecopetrol’s equity share in said company is 43.35%. The dividends paid in relation to the shares returned to Ecopetrol are also subject to controversy. As of December 31, 2017, the settlement of these claims is still pending.

18. Impairment of long-term assets

 

As mentioned in Note 4.12, each year the Group assesses whether there are indications of impairment of its assets or cash-generating units or whether an impairment loss recognized in previous periods may be reversed.

  

The impairment of our non-current assets includes expenses (or recovery) of impairment of property, plant and equipment and natural resources, investments in companies, goodwill and other non-current assets. The Group is exposed to future risks derived mainly from variations in: (i) the oil prices outlook, (ii) refining margins and profitability, (iii) cost profile, (iv) investments and maintenance expenses, (v) amounts of recoverable reserves, (vi) market and country risk assessments reflected in the discount rate, and (vii) changes in domestic and international regulations, among others.

 

Any change in the foregoing variables used to calculate the recoverable amount of a non-current asset can have a material effect on the recognition or either losses or recovery of impairment charges in the profit or loss statement. In our business segments highly sensitive variables can include, among others: (i) in the exploration and production segment, variations of the hydrocarbon prices outlook; (ii) in the refining segment, changes in product and crude oil prices, discount rate, refining margins, changes in environmental regulations, cost structure and the level of capital expenditures; and (iii) in the transport and logistics segment, changes in tariffs regulation and volumes transported.

 

Expense (recovery) for impairment

 

Based on impairment tests conducted by the Group, the following (recoveries) losses for impairment of long term assets for the years ended December 31, 2017, 2016 and 2015 are presented:

18.1.1 Oilfields

 

In 2017, based on new market variables, incorporation of new reserves, Ecopetrol’s crude oil basket price discounts as compared to the ICE Brent crude price, available technical and operational information, there was a partial reversal of an impairment recognized in previous years for the oil fields that operate in Colombia CPO09, Casabe and Oripaya and in fields operated abroad Gunflint Dalmatian and K2, and an impairment in the Tibú, Underriver, Provincia and Orito fields.

 

In 2016, as a result of the revision of prospective oil prices in the long term, it was identified that some impairments recognized in previous years for oil fields could be recovered due to an improved future price scenarios. The main fields on which there was a recovery of impairment were Chichimene, Caño Sur, Apiay and Llanito. Similarly, the new technical information and operational aspects that gave rise to changes in investment levels caused an impairment in the Casabe, Tibú, Gunflint and Niscota fields.

 

The breakdown of the expenses for (recovery of) impairment of fields for the years ended December 31, 2017, 2016 and 2015 includes:

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

The assumptions used in the model to determine the recoverable amount include:

 

- The fair value less costs of disposal of the Exploration and Production segment assets was determined based on cash flows after tax derived from the business plans approved by Group's management, which are developed based on long-term macroeconomic policies and fundamental assumptions of supply and demand. The fair value category is level 3.

 

- Balance of oil and gas reserves, in addition to proven reserves included in Note 34; probable and possible reserves were also considered, adjusted by different risk factors.

 

- The real discount rate determined as the average weighted cost of capital of market participants (WACC) established for each company in the segment with rates ranging between 7.9% and 8.9% (2016 – 7.9% and 8.9%).

 

- Oil price - Brent: The forecasts include US$52.9/barrel for 2018, US$72.5/barrel average for the next six years and US$81.9/barrel as of 2030. In 2016, the assumptions made used a price of US$56.8/ barrel in 2017, US $67.9/barrel average for the medium term and US$80/ barrel in the long term. International oil price projections were carried out by an independent agency specializing in oil and gas, which takes into account the current scenarios of oil quota agreements of the OPEC (Organization of Petroleum Exporting Countries) and the impact of the changes in specifications issued by the international agreement to prevent pollution by ships (Marpol) as of the year 2020 on crude and fuels with high sulfur content.

 

The aggregation of assets to identify the CGUs is consistent as compared to the previous period.

 

18.1.2 Investment in associates and joint ventures from Exploration and Production segment

 

Investments in associated companies and joint ventures in the segment are recorded through the equity method. Ecopetrol evaluates if there is any objective evidence to determine if the value of such investments has deteriorated in the period, especially those Companies that were acquired with goodwill.

 

As a result, Ecopetrol recognized an expense for (recovery of) impairment in the value of its investments in companies as of December 31, as follows:

 

    2017     2016     2015  
Equion Energy Limited     42,744       81,155       172,528  
Offshore International Group     (37,589 )     46,703       415,616  
Total     5,155       127,858       588,144  

 

The assumptions used to determine the recoverable amount of the companies assessed are those described in Note 18.1.1, except for the use of a discount rate in real terms in 2017 for Equion Energía Limited of 8.2% (2016 - 8.9%) and for Offshore International Group of 8.6% (2016 - 8.0%).

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

In 2017, because of new market variables, new reserves, price differentials against reference indicators, and available technical and operational information, there was a recovery of an impairment recognized in previous years for Offshore International Group and Equion Energy .

 

For 2016, in spite of better forecasts of oil prices in the long term, there was an additional impairment in the investment in the Offshore International Group for the reversion to local authorities of some low-prospective success exploration blocks, high geological risk, and low economic viability with respect to a new price scenario.

 

18.2 Refining and Petrochemical segment

 

The Cash Generating Units with an expense for (recovery of) impairment in the Refining and Petrochemical segment for the years ended December 31 of 2017, 2016 and 2015 include:

      27,203,474       23,924,482       3,278,993  

 

The aggregation of assets for identifying the CGUs is consistent across these periods.

 

18.2.1 Refinería de Cartagena

 

The recoverable amount of the Refinería de Cartagena was calculated based on the fair value less costs of disposal, which is higher than its value in continued use. The fair value less costs of disposal of the Refinería de Cartagena was determined based on cash flows after taxes that are derived from business plans approved by the Group's management, which are developed based on market prices provided by a third party expert, which considers long-term macroeconomic variables and fundamental supply and demand assumptions for crude and refined products. The fair value category is level 3.

 

The assumptions to determine the recoverable amount included: a) a gross refining margin determined by crude oil feedstock and products price outlook provided by an independent third party expert; b) an actual discount rate of 6.0% (2016 - 6.3%) determined under WACC methodology; c) current conditions or benefits, or similar, as an industrial user of goods and services of the free trade zone and during the validity of the license; d) level of costs and long-term operating expenses in line with international refinery standards of similar configuration and conversion capacity, e) refinery throughput and production, and f) level of continued investment.

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

In 2017, we recorded a partial reversal of the impairment recorded in previous periods primarily as a result of: a) an improved outlook in refining margins due to the ratification of the implementation of the International Convention for the Prevention of Pollution from Ships (Marpol) starting in 2020; b) a lower discount rate resulting from the application of WACC methodology; and c) operational and financial optimizations identified as part of the stabilization of the refinery.

 

In 2016, we recorded an impairment caused mostly by adjustment of operational variables based on what was that observed during the stabilization period, offset by a lower discount rate and better refining margins.

 

18.2.2 Refinería de Barrancabermeja

 

In compliance with the provisions of IAS 36 - Impairment of the value of assets, during 2017 the Refinería de Barrancabermeja recognized COP$273,987 for impairment, mainly related to the write off of certain management and financial capitalized balances associated with the suspended the modernization project of the Refinery. This suspension is in response to capital discipline criteria implemented to ensure the growth and financial sustainability of Ecopetrol S.A. and the Ecopetrol Business Group in the adverse context that the hydrocarbons sector experienced in previous years. This project is being assessed within the Group’s strategic plan; and when the project is reactivated, any impairment loss recognized in previous years may be subject to recovery.

 

18.2.3 Bioenergy

 

The recoverable amount of Bioenergy was calculated based on the fair value less the costs of disposal level with value hierarchy 3, which is greater than the value in continued use and corresponds to the future cash flows discounted after taxes on profit.

 

The assumptions used in the model to determine the recoverable amount included: a) forecast of ethanol prices based on projections made by Ecopetrol specialists based on independent third party sources; and b) a 6.2% discount rate in real terms (2016 – 6.7% in real terms) determined under the WACC methodology.

 

In 2017 and 2016, we recorded an impairment mainly due to updating of the dates of entry into operation of the project, the stabilization process of the industrial plant, and the updating of operational variables.

 

18.3 Transport and Logistics segment

 

In 2017, there was a recovery of an impairment for the Transportation and Logistics segment for COP$59,455, mainly in Oleoducto del Sur, which includes, among others, the Trans Andino Pipeline. The recovery was due to the inclusion of the Port of Tumaco in that generating unit.

 

The recovery of COP$41,062 in 2016 was caused mainly by the incorporation of flows associated with the San Fernando - Apiay system project, which affects the recoverable amount of Los Llanos transport line, but was offset by the impairment of the Sur transport line.

 

The recoverable amount of these assets was determined based on its fair value with costs of disposal with value hierarchy 3, which corresponds to discounted cash flows based on the hydrocarbon production curves and tariffs regulated by the Ministry of Mines and Energy and the Energy and Gas Regulating Commission - CREG. The real discount rate used in the valuation was 5.0% (2016 -4.98%).

19. Goodwill

 

The balance as of December 31, 2017 and 2016 of goodwill in acquisitions of subsidiaries is as follows:

 

    2017     2016  
Transport and Logistics                
Oleoducto Central S.A.     683,496       683,496

Andean Chemical Ltd     127,812       127,812  
Propilco S.A     108,137       108,137  
      1,457,043       1,457,043  
Less impairment Hocol Petroleum Ltd.     (297,121 )     (297,121 )
      1,159,922       1,159,922  

 

As of December 31, 2017 and 2016, the Group assessed the recoverability of the carrying value of goodwill generated in the acquisition of subsidiaries. The recoverable amount was determined based on the realization value less costs of disposal using the present value of future cash flows for each of the companies acquired with goodwill. The source of information used the financial projections of each company derived from the business plans approved by management, which were developed based on long term macro-economic factors such as price curves and margins and fundamental assumptions of supply and demand. As a result of the analysis, the Group did not recognize any goodwill impairment.

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

Until December 13, 2017, when Ecopetrol voluntarily assumed the international loan held by Reficar, in its capacity as sponsor, the following restrictions applied to Reficar: maintain a minimum debt service coverage ratio of 1.35:1; obligation to maintain a commercial trust and a depositary agreement for receiving resources of the new refinery to fulfill specific purposes such as operating expenses, interest and others.

 

The following is a summary of certain restrictions contained in certain loan instruments of Ecopetrol’s subsidiaries:

 

- The loan entered into by Oleoducto de los Llanos is guaranteed with the economic rights of the ship-or-pay transportation agreements with Meta Petroleum Corp and also includes certain restrictions regarding capital contributions and asset disposal.

 

- The syndicated loan entered into by Oleoducto Bicentenario requires that this subsidiary maintain an established relationship of leverage and solvency and cash flow / service to the debt.

 

- The loan entered into by Bioenergy with Bancolombia is guaranteed with the La Esperanza 1 and 2 fields in the amount of COP$6,343 and there are certain restrictions on the variation of direct or indirect ownership by Ecopetrol S.A. in this subsidiary.

 

Ecopetrol and its subsidiaries were in compliance with these restrictions as of December 31, 2017 and 2016.

 

20.7 Fair value of loans

 

The fair value of loans and borrowings is COP$45,781,317 and COP$52,109,438 as of December 31, 2017 and 2016, respectively.

 

For fair value measurement, local currency bonds were valued using Infovalmer reference prices, while bonds in U.S. dollars, were valued using Bloomberg. With regard to the other financial obligations for which there is no market benchmark, a discount to present value technique was used. These rates incorporate market risk through some benchmarks (Libor, DTF) and the Group’s credit risk (spread).

22.2 Plan assets

 

Plan assets are resources held by pension trusts, for payment of pension obligations. Payments for health and education post-employment benefits is Ecopetrol’s responsibility. The destination of trust resources and its yields cannot be changed or returned to the Group until all pension obligations have been fulfilled.

 

The following is the composition of the plan assets of pension and pension bonds by type of investment as of December 31, 2017 and 2016:

 

    2017     2016  
Bonds issued by the national government     4,349,400       4,410,326  
Bonds of private entities     2,967,030       2,880,958  
Other local currency     2,337,580       2,910,083  
Other public bonds     1,149,200       693,061  
Variable yield     605,380       305,052  
Bonds of foreign entities     558,920       622,817  
Other foreign currency     503,653       300,878  
      12,471,163       12,123,175  

 

46.0% of plan assets are classified as level 1 in the fair value hierarchy, where prices for the assets are directly observable on actively traded markets, and 54.0% are classified as level 2.

 

The fair value of level 2 plan assets is calculated using prices quoted in the assets’ market. The Group obtains these prices through reliable financial data providers recognized in Colombia or abroad depending on the investment.

 

For the securities issued in local currency, the fair value of plan assets is calculated using information published by Infovalmer, a price supplier authorized by the Financial Superintendence of Colombia. According to its methodology, prices are calculated based on market information on the valuation date or estimated from historical inputs according to the criteria established for the calculation of each of the prices.

 

The average price is calculated based on the most representative market of the transactions carried out through electronic platforms approved and supervised by the regulator.

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

On the other hand, the estimated price is calculated for investments that do not reflect enough information to estimate an average market price, replicating the quoted prices for similar assets or prices obtained through quotes from brokers. This estimated price is also given by Infovalmer as a result of the application of robust methodologies approved by the financial regulator and widely used by the financial sector.

23.1 Asset retirement obligation

 

The estimated liability for asset retirement obligation costs corresponds to the future obligation to restore environmental conditions to a level similar to that existing before the start of projects or activities, as described in Note 3.5 - Abandonment and dismantling costs of fields and other facilities. As these relate to long-term obligations, this liability is estimated by projecting the expected future payments and discounting at present value with a rate indexed to the Group's financial obligations, taking into account the temporality and risks of this obligation. The discount rates used in the estimate of the obligation as of December 31, 2017 were: Exploration and Production 6.93% (2016 - 7.93%), Transportation and Logistics 7.02% (2016 - 8.20%) and Refining and Petrochemicals 7.37% (2016 - 8.99%).

23.2 Litigation

 

The following is a summary of the main legal proceedings recognized in the statement of financial position whose amount exceeds COP$13,000 million, where the expectation of loss is probable and could imply an outflow of resources as of December 31, 2017 and 2016:

 

Proceeding   2017     2016  
             
Provision for the payment of the 2016 legal stability contract premium with the Ministry of Finance and Public Credit regarding investment in Reficar     64,104       59,528  
Litigation with Schrader Camargo, supplier of Reficar     17,003       17,003  
Settlement before the Procuraduría General de la Nación with the firms Acciona Infraestructura S.A. and Mantenimiento y Montajes S.A., August 18, 2016. In 2017, it was ruled in favor of the Group and the provision was reversed.     -       44,986  

 

23.3 Comuneros - Santiago de las Atalayas provisions

 

On November 8, 2016, the Ministry of Mines and Energy concluded that the resources that were restricted in relation to this process were not royalties and, therefore, were not due to the Comuneros.

 

In accordance with the foregoing, the resources held by Ecopetrol are its property, without any claim or discussion to date regarding ownership title thereof. On November 8, 2016, the amount claimed reached COP$688,664, originated mostly from the valuation and financial yield of the fund where the resources were deposited. The recovery of this provision was recognized in the net financial results of the period ending December 31, 2016.

 

23.4 Environmental contingencies and others

 

These corresponds to contingencies for environmental incidents and obligations related to environmental compensation and mandatory investment of 1% for the use of, exploitation of or effect on natural resources imposed by national, regional and local environmental authorities. Mandatory investment of 1% is based on the use of water taken directly from natural sources in accordance with the provisions of Law 99 of 1993, Article 43, Decree 1900 of 2006, Decree 2099 of 2017 and 075 and 1120 of 2018 in relation to the projects that Ecopetrol develops in Colombia.

 

The Colombian Government through the Ministry of Environment and Sustainable Development, issued in December 2016 and in January 2017 the Decrees 2099 and 075, which modify the Single Regulatory Decree of the environment and sustainable development sector, Decree 1076 of 2015, related to the mandatory investment for the use of water taken directly from natural sources.

 

The main changes established by these decrees were related to the areas and lines of investment and the basis for settlement of the obligations. Similarly, June 30, 2018 was declared the maximum date to modify investment plans that were underway.

 

On June 30, 2017, Ecopetrol filed with the National Environmental Licensing Authority (ANLA) certain investment plans to meet the 1% mandatory investment based on the new decrees, relative to investment lines, maintaining the settlement base of Decree 1900.

 

As of December 31, 2017, the provision for the 1% mandatory investment for the use of water was estimated based on the parameters established in Decree 1076 of 2015. The Group is in the process of analyzing the impact of the applicability of the changes set out in the aforementioned decrees.

Legal reserve

30. Risk management

 

30.1 Commodity price risk

 

Ecopetrol’s business is significantly impacted by international prices for crude oil and refined products. The prices for these products are volatile and drastic changes could adversely affect the Group business prospects and results of operations.

 

A large proportion of Ecopetrol’s sales revenues come from sales of crude oil, natural gas and refined products. These products are indexed to international reference prices such as the Brent index. Consequently, fluctuations in those international indexes have a direct effect on the financial condition and Group’s results of operations.

 

Prices of crude oil, natural gas and refined products have historically fluctuated as a result of a variety of factors including, among others, competition within the oil and natural gas industry; changes in international prices of natural gas and refined products; long-term changes in the demand for crude oil, natural gas and refined products; regulatory changes; changes in the cost of capital; adverse economic conditions; transactions in derivative financial instruments related to oil and gas and development or availability of alternative fuels.

 

The Ecopetrol Business Group has a policy approved by the Board of Directors that allows it to use derivative financial instruments in the organized over the counter (OTC) market to cover itself from the risk of price fluctuations of crude oil and refined products associated with physical transactions. The Group has established appropriate processes to handle risk which include constant monitoring of physical and financial markets to identify risks in order to subsequently prepare and execute hedging strategies.

Ecopetrol S.A.

Notes to the consolidated financial statements

(Figures expressed in millions of Colombian pesos, unless otherwise stated)

 

Ecopetrol does not regularly use derivative instruments to hedge exposures to sales or purchase price risks. The impact of the settlement of the price hedges made in 2016 and 2015 was not material and was made as hedging instruments to mitigate risk at different price indices to the benchmark of the Group's international trade strategy on exports of crude and imports of products.

 

In 2017, hedging transactions were not carried out with derivative instruments. In 2016 and 2015, then outstanding price hedges were settled in full, with an impact on the result of the period of COP$3,181 and COP$4,141, respectively.

 

30.2 Exchange rate risk

 

The Ecopetrol Business Group operates mainly in Colombia makes sales in the local and international markets. It is exposed to exchange rate risk, which arises from various foreign currency exposures due to commercial transactions and assets and liabilities denominated in foreign currency. The impact of exchange rate fluctuations, especially the Colombian peso/U.S. dollar exchange rate, has been material in previous years. To mitigate this risk, the Group's risk management strategy involves the use of non-derivative financial instruments related to cash flow hedges for future exports and net investment of foreign operations to minimize exchange rate risk exposure.

 

The U.S. dollar/Colombian peso exchange rate has fluctuated over the last few years. The Colombian peso appreciated on average by 3.3% in 2017. During 2016 and 2015, the Colombian peso depreciated by 11.2% and 37.3%, respectively. The closing exchange rates were COP$2,984.00 COP $3,000.71 and COP $3,149.47 to US$1.00 for 2017, 2016 and 2015, respectively.

 

When the Colombian peso appreciates in relation to the U.S. dollar, export sales revenue decreases when converted to Colombian pesos; however, imported goods, oil services and interest on foreign debt denominated in U.S. dollars become less expensive. Conversely, when the Colombian peso depreciates, export revenues, when translated to Colombian pesos, increases, and imports and servicing of the external debt become more expensive.

 

The following table sets out the carrying amount for financial assets and liabilities denominated in foreign currency as of December 31, 2017 and 2016:

 

(in US$ Million)   2017     2016  
Cash and cash equivalents     1,203       1,916  
Other financial assets     1,072       1,367  
Trade receivables and payables, net     (7 )     (282 )
Loans and borrowings     (12,590 )     (15,172 )
Net liability position     (10,322 )     (12,171 )

 

Of the total net liability position, US$8,532 million relates to financial liabilities designated as non-derivative hedging instruments of Ecopetrol, on which unrealized foreign exchange gains and losses are recognized in other comprehensive income, within equity. Likewise, US$ 1,699 million corresponds to the net liability position in U.S. dollars of Ecopetrol Business Group companies whose functional currency is the U.S. dollar, without affecting profit or loss and US$91 million correspond to the net liability position in U.S dollars of Ecopetrol Business Group companies whose functional currency is Colombian pesos with foreign exchange affects the profit or loss.

30.2.1 Sensitivity analysis for exchange rate risk

 

The Group’s risk management strategy involves the use of non-derivative financial instruments related to cash flow hedges for future exports and hedges of a net investment in a foreign operation in order to minimize exposure to currency rate risk, which is detailed below. The following is the effect of a change of 1% and 5% in the exchange rate of the Colombian peso as compared with the U.S. dollar, on the balance of financial assets and liabilities denominated in foreign currency as of December 31, 2017:

 

Scenario / Variation in
the exchange rate
    Effect on income
before taxes (+/-)
    Effect on other
comprehensive income (+/-)
 
  1 %     2,715       305,293  
  5 %     13,577       1,526,465  

 

The sensitivity analysis only includes financial assets and liabilities in foreign currency at the closing date.

 

30.2.2 Cash flow hedge for future exports

 

Ecopetrol is exposed to foreign exchange risk given that a significant percentage of its income from crude oil exports is denominated in U.S. dollars. In recent years, the Group has acquired long-term debt for investment activities in the same currency in which it expects to receive the cash flow of its export sales revenues. This situation creates a natural hedge relationship due to the fact that the risks generated by the foreign exchange difference of export sales revenues when booked in Ecopetrol’s functional currency (Colombian pesos) are naturally hedged with the foreign exchange variances of the long-term debt, in line with the Group's risk management strategy.

 

With the objective of presenting in the financial statements the effect of the existing natural hedge between exports and debt, understanding that the exchange rate risk materializes when the exports are made, on October 1, 2015, the Board of Directors designated the sum of US$5,440 million of Ecopetrol's foreign currency debt as a hedge instrument of future revenue from crude oil exports, for the period 2015-2023, in accordance with IAS 39 - Financial instruments: Recognition and Measurement.

 

Hedge accounting records the impact on the statement of profit or loss at the time of realization of the hedged risk. For this to happen, every month when foreign currency debt is converted to Colombian pesos based on the closing rate for the period, the effects for exchange difference are recognized in other comprehensive income, within equity and, as crude oil exports take place and the hedge occurs and sales revenue is recognized, cumulative exchange differences held within other comprehensive income are reclassified to profit or loss statement, impacting operating income.

 

The following is the movement of foreign currency debt designated as a non-derivative hedging instrument for the years ended December 31, 2017 and 2016:

 

(US$ Million)   2017     2016  
Hedging instrument at the beginning of the period     5,312       5,376  
 Reassignment of hedging instruments     1,803       870  
 Realization of exports     (1,803 )     (870 )
 Capital payments (1)     (1,980 )     (64 )
  Hedging instrument at the end of the period     3,332       5,312  

 

(1) On June 30, 2017, Ecopetrol prepaid the entire outstanding balance of the international syndicated loan whose nominal value was US$ 1,925 million and original maturity date was in February 2020.

      245,173       (85,879 )     159,294  

 

30.2.3 Hedge of a net investment in a foreign operation

 

The Board of Directors approved the application of net investment hedge accounting from June 8, 2016. The measure is intended to reduce the volatility of non-operating income due to exchange rate variations. The net investment hedge will be applied on a portion of Group’s investments in foreign operations, in this case on investments in subsidiaries which have the US dollar as their functional currency, using a portion of the Group’s US dollar denominated debt as the hedging instrument.

 

Ecopetrol designated the net investments in Ocensa, Ecopetrol America Inc., Hocol Petroleum Ltd. (HPL) and Reficar and as hedged items and as a hedging instrument and US$5,200 million of the Group’s US dollar debt as the hedging instrument.

 

The following is the movement of accumulated foreign currency gains and losses in respect of the net investment hedge recognized in other comprehensive income for the years ended December 31, 2017 and 2016:

 

    2017     2016

30.2.4 Hedging with derivatives to minimize currency risk

 

The Group carries out forwards hedging operations using the Non-Delivery modality, for mitigating the volatility of the exchange rate in the cash flow required for operations of its subsidiary, Ocensa, whose functional currency is the US dollar. The forward hedging instruments used enable setting sales prices in US dollars, mitigating the foreign exchange variation given Ocensa’s obligations relative to operational cost and tax payments are payable in Colombian pesos. The accounting policy applicable to this operation is described in the Note 4.1.5.1.

 

As of December 31, 2017, there are forward contracts with a net short position for US$325 million (2016 - US$323 million) with maturities between January and December 2018.

 

The impact on the statement of profit or loss for the settlement of these hedges amounted to COP$99,971 (2016- COP$42,865 of profit) and the amount recognized in the other comprehensive income was a gain of COP$35,769 (2016 gain of COP$33,869).

 

30.3 Credit risk

 

Credit risk is the risk that the Group may suffer financial losses as a consequence of default of: a) payments by its clients for the sale of crude oil, gas, products or services; b) financial institutions in which it keeps investments, or c) by counterparties with which it has contracted financial instruments.

 

30.3.1 Credit risk for customers

 

In the selling process of crude oil, gas, refined products and petrochemicals, and transport services, the Group may be exposed to credit risk in the event that customers fail to fulfill their payment obligations. The Group’s risk management strategy has designed mechanisms and procedures that aim to minimize such events, thus safeguarding the Group's cash flow.

 

The Group performs a continuous analysis of the financial strength of its counterparties, by classifying them according to their risk level and financial guarantees in the event of a default of payments. Similarly, the Group continuously monitors national and international market conditions for early alerts of major changes that may have an impact on the timely payment of obligations from customers of the Group.

 

Allowances for loan losses are set by individual analysis of each customer’s situation. The Group performs administrative and legal actions required to recover amounts past due and charges interest from customers that fail to comply with payment policies.

 

Ecopetrol does not have a significant concentration of credit risk. An aging analysis of the accounts receivable portfolio in arrears, but not impaired, as of December 31, 2017 and 2016 is as follows:

 

    2017     2016  
Less than 3-month overdue     65,354       179,008  
Between 3- and 6-month overdue     1,131       14,275  
More than 6-month overdue     79,688       103,574

30.3.2 Credit quality of resources in financial assets

 

Following the promulgation of Decree 1525 of 2008, which provides general rules on investments for public entities, Ecopetrol’s management established guidelines for our investment portfolios. These guidelines determine that investments in Ecopetrol’s U.S. dollar portfolio are generally limited to investments of our excess cash in fixed-income securities issued by entities rated A or higher in the long term and A1/P1/F1 or higher in the short term (international scale) by Standard & Poor’s Ratings Services, Moody’s Investors Service or Fitch Ratings. In addition, Ecopetrol S.A. may also invest in securities issued or guaranteed by the U.S. government or Colombian government, without regard to the ratings assigned to such securities. In Ecopetrol’s Colombian Peso portfolio, it must invest our excess cash in fixed-income securities of issuers rated AAA in the long term, and F1+/BRC1+ in the short term (local scale) by Fitch Ratings Colombia or BRC Standard & Poor’s. In addition, Ecopetrol may also invest in securities issued or guaranteed by the Colombian government without rating restrictions.

 

In order to diversify risk in our Colombian Peso portfolio, Ecopetrol does not invest more than 10% of the excess of cash in one specific issuer. In the case of our U.S. dollar portfolio, it does not invest more than 5% of the excess of cash in one specific issuer in the short term (up to one year), or 1% in the long term.

 

Ecopetrol’s investment portfolio in U.S. dollars is segmented into four tranches, each one matching our liquidity needs. The working capital tranche is calculated taking into account our cash flow needs for the next 60 days. The liquidity tranche is calculated as the contingent cash flow needs over the working capital, taking into account the development of capital expenditures related to projects. The asset liability tranche is built to match our long-term debt. The investment tranche includes the remaining amount of the total portfolio after deducting the amounts pertaining to the above mentioned tranches and after subtracting the Colombian Peso portfolio.

 

Ecopetrol’s investment portfolio in Colombian Pesos is segmented in two tranches, each one matching our liquidity needs. The first tranche is calculated taking into account our cash flow needs for the next 30 days, and the second tranche is built for investment purposes.

 

The credit rating of issuers and counterparties in transactions involving financial instruments is disclosed in Note 6 - Cash and cash equivalents, Note 7 - Other financial assets and Note 21 - Provisions for employee benefits.

 

30.4 Interest rate risk

 

Interest rate risk arises from Ecopetrol’s exposure to changes in interest rates because the Ecopetrol Business Group has investments in fixed and floating-rate instruments and has issued floating rate debt linked to LIBOR, DTF and IPC interest rates. Thus, interest rate volatility may affect the fair value and cash flows of the Group's investments and the financial expense of floating rate loans and financing.

 

As of December 31, 2017, 19% (2016, 31%) of the Group’s indebtedness is linked to floating interest rates. As a result, if market interest rates rise, financing expenses will increase, which could have an adverse effect on the results of operations.

 

Ecopetrol controls the exposure to interest rate risk by establishing limits to exposure duration, Value at Risk - VAR and tracking error.

 

Autonomous equities linked to Ecopetrol’s pension obligations are also exposed to changes in interest rates, as they include fixed and floating rate instruments that are marked to market. Colombian regulation for pension funds, as stipulated in the Decree 941 of 2002 and Decree 1861 of 2012, indicates that they have to follow the same regime as the regular obligatory pension funds in their moderate portfolio.

30.5 Liquidity risk

 

The ability to access capital necessary to finance the Group’s investment plans on acceptable terms can be limited due to deterioration in market conditions. A new financial crisis could worsen risk perception in emerging markets.

 

Events impacting the political and regional environment of Colombia, could make it difficult for our subsidiaries to access capital markets. These conditions, together with potential significant losses in the financial services sector and changes in credit risk assessments, may make it difficult to obtain financing on favorable terms. As a result, the Group may be forced to review the opportunity and scope of its investment plans as necessary, or access financial markets under less favorable terms, thereby negatively affecting the Group’s results of operations and financial position.

 

Liquidity risk is managed in accordance with the Group’s policies aimed at ensuring that there are sufficient net funds to meet the Group's financial commitments within its maturity schedules with no additional costs. The main method for the measurement and monitoring of liquidity is cash flow forecasting.

 

During 2017, the Group used US$2,400 million as part of its liquidity surpluses to prepay part of its foreign currency debts that had original maturities between 2020 and 2021. The details of these movements are described in Note 20 - Loans and borrowings.

 

The following is a summary of the maturity of financial liabilities as of December 31, 2017. The amounts disclosed in the table are the contractual undiscounted cash flows. The payments in foreign currency were restated taking a constant exchange rate of COP$2,984.00 per US dollar. Consequently, these amounts may not reconcile with the amounts disclosed on the consolidated statement of financial position:

 

    Up to 1 year     1-5 years     5-10 years     > 10 years     Total  
Loans (payment of principal and interest)     5,040,130       28,151,892       18,873,280       15,484,650       67,549,952

30.6 Capital management

 

The main objective of the capital management of the Ecopetrol Business Group is to ensure a financial structure that optimizes the cost of capital, maximizes the rate of return to its shareholders and allows access to financial markets at a competitive cost to cover financing needs that support an investment grade credit rating profile.

 

Net financial debt is calculated by taking short-term and long-term loans and borrowings less cash and cash equivalents and investments in securities as of December 31 of each year. The level of leverage is calculated as the ratio between net financial debt and the sum of equity and net financial debt. The following is the information of these indicators as of December 31, 2017 and 2016:

 

    2017     2016  
Loans and borrowings (Note 20)     43,547,835       52,222,027  
Cash and cash equivalents (Note 6)     (7,945,885 )     (8,410,467 )
Other financial assets (Note 9)     (6,533,725 )     (6,686,895 )
Net financial debt     29,068,225       37,124,665  
Equity (Note 24)     48,215,699       43,560,501  
Leverage     37.61 %     46.01 %

 

The movement of the net financial debt is detailed in Note 20.8.

31.1 Key executives management

 

In accordance with the approval given by the shareholders’ meeting in 2012, compensation paid to directors for attending the meetings of the Board of Directors and / or committees increased from four to six minimum legal monthly salaries in force, or approximately to COP$4,426,000 for 2017, from COP$4,140,000 for 2016 and COP$3,870,000 for 2015. For non-face-to-face sessions, 50% of the quota for face-to-face meetings is set. The members of the Board of Directors do not have any kind of variable remuneration. The amount paid in 2017 for compensation to members of the Board of Directors amounted to COP$1,877 (2016 - COP$1,253).

 

The total compensation paid to Directors as of December 31, 2017 amounted to COP$20,669 (2016 - COP$13,901). Directors are not eligible to receive pension and retirement benefits. The total amount reserved as of December 31, 2017 to provide pension and retirement benefits to our eligible executive officers amounted to COP$5,401 (2016 - COP$4,674).

 

As of December 31, 2017, the following key management officers owned less than 1% of the outstanding shares of Ecopetrol S.A. as follows:

 

Key management personnel   % Shares
Felipe Bayón   <1% outstanding shares
Mauricio Cárdenas Santamaría   <1% outstanding shares  
Héctor Manosalva Rojas    <1% outstanding shares  
Rafael Espinosa Rozo   <1% outstanding shares

 

31.2 Post-employment benefit plans

 

The administration and management of resources for payment of Ecopetrol's pension obligations are managed by autonomous pension funds (PAPs, by its acronym in Spanish) which serve as guarantee and payment sources. These funds were established in compliance with the provisions of Decree 2153 of 1999 which authorized, as of December 31, 2008 partial commutation of the value corresponding to monthly payments, bonuses and contributions, transferring said obligations and money supporting them to autonomous patrimonies for pensions.

 

As of December 31, 2017 and 2016, the entities managing these resources were: Fiduciaria Bancolombia, Fiduciaria de Occidente and Consorcio Ecopetrol PAAC (comprised of Fiduciaria La Previsora, Fiduciaria Bancoldex, Fiduciaria Agraria and Fiduciaria Central). These entities will manage pension resources for a five-year term (2016 - 2021) and as consideration they receive a remuneration with fixed and variable components which is calculated on the gross yield of the portfolios and are charged to manage resources.

31.3 Government related parties

 

The Colombian Government controls Ecopetrol with a stock ownership of 88.49%. The most significant transactions with governmental entities are comprised as follows:

 

a) Purchase of oil from the National Hydrocarbons Agency - ANH

 

The Group has a direct relationship with ANH, an entity which operates under the rules of the Ministry of Mines and Energy, whose objective is to manage the oil and gas reserves and resources owned by the Colombian Nation.

 

Ecopetrol purchases the crude oil that the ANH receives from all producers in Colombia at the prices set in accordance with a jointly established formula, which reflects the export sale prices (crude oils and products), adjusted for API gravity quality, sulfur content, transportation rates from the wellhead to the ports of Coveñas and Tumaco, refining process cost and a commercialization rate. This contract was extended to June 30, 2018.

 

From December 2013 the Group commercialized, on behalf of the ANH, the natural gas received by the latter in kind from producers. Since January 2014, ANH has received royalties in cash for the production of natural gas.

 

The purchase value of oil and gas from ANH is detailed in Note 26 - Cost of sales.

 

Additionally Ecopetrol, like other oil companies, takes part in "rounds" for the allocation of exploration blocks in Colombia without implying special treatment for Ecopetrol on account of it being an entity whose majority shareholder is the Colombian Government.

 

b) Price differential

 

Regular gasoline and diesel sale prices are regulated by the National Government. In this case, there are differentials between the volume reported by the Colombian companies at the time of the sale and the difference between the international parity price and the regulated price actually charged, where the parity price is the daily price of gasoline and diesel oil of the respective month in Colombian pesos, indexed to the United States of America Gulf market, calculated in accordance with Resolution 18 0522 of 2010 and the Producer Price reference defined by the Ministry of Mines and Energy. These differentials may be in favor or against the producers. The value of this differential is detailed in Note 25 - Sales revenue and 7 – Trade and other receivables, net.

 

c) National Tax and Customs Direction

 

Ecopetrol, just like any other company in Colombia, has tax obligations that it must comply with and does not have any other kind of association or commercial relationship with the National Tax and Customs Direction. For more information see Note 10 – Taxes.

 

d) Comptroller General of the Republic

 

Ecopetrol, just like any other state entity in Colombia, is obliged to comply with the requirements set out by the Comptroller General of the Republic and make an annual payment to this entity on account of a maintenance fee. Ecopetrol does not have any other kind of association or commercial relationship with this entity.

32.3 Relevant operations during the period

 

During 2017 and 2016, the following significant events occurred in respect of our joint operations contracts:

 

a) Acquisition of interests in joint operations

 

On December 11, 2017, Ecopetrol América Inc. acquired the 11.6% interest in the K2 oil field in the Gulf of Mexico MCX Exploration USA LLC (“MCX”), increasing its share from 9.2% to 20.8%.

 

The acquisition of MCX’s interest was recognized in accordance with policy 4.4 Joint Operations. To determine the fair value of the assets acquired and liabilities assumed, the income approach model was used, using the discounted cash flow and market data to determine the fair values of oil and gas properties. This model incorporated future commodity prices, estimated volumes of oil and gas reserves, future developments, operating costs, future abandonment and packing costs and a risk adjusted discount rate.

 

The fair value of the consideration transferred in the operation was US$47.6 million (COP$141,950), the fair value of the net assets acquired was US$198.4 million before deferred taxes (US$146 million net of deferred taxes) with recognition of a gain of US$150.8 million before deferred taxes (US$98 million after deferred taxes) in the period’s statement of profit or loss (equivalent to COP$451,095 before deferred taxes), mainly due to the transaction price being fixed before the closing date of the transaction and the fair value of the net identifiable assets acquired having increased during the interim period.

 

Transaction costs incurred in the operation amounted to US $ 0.2 million, recognized in profit or loss for the year.

 

b) Termination of the Rubiales and Pirirí field contracts

 

On July 1, 2016, Ecopetrol took over the direct operation of the Rubiales and Pirirí fields, which up to that date had been operated by Pacific Rubiales Energy. Upon termination of the contract Ecopetrol gained control over the assets and the obligations associated with the BOMT contracts for US$46 million.

 

c) Termination of the Tauramena association agreement

 

On July 3, 2016, the Tauramena Association Agreement was terminated and for this reason, Ecopetrol began to operate directly the Cusiana field, Casanare. Since its commercialization in 1993, it was operated first by BP and then by Equion. Cusiana represents for Ecopetrol a 98% participation in the Unified Exploitation Plan (PEU) of the field, while Equion and Emerald maintain 2%.

The Group has several commitments and contractual obligations that may require future disbursement of funds. The main commitments are related to a) payments of loans and borrowings, which are disclosed in Note 30.5, b) payment of benefits post-employment, the amounts of which in the next 5 years are disclosed in Note 22.4 c) future payment commitments in service contracts, operational leasing, gas and energy supplies, purchase of assets and others, and d) commitments of exploration activities and others with the National Hydrocarbons Agency in current contracts.

 

The details of the commitments and contractual obligations can be found in section 4.8 Financial Review - Financial Indebtedness and Other Contractual Obligations.

 

35. Subsequent events

 

- On April 13, 2018, Ecopetrol redeemed all of its outstanding 4.250% notes due September 18, 2018 in an aggregate principal amount of US$350 million. The notes were issued in September 2013.

 

- On March 14, 2018, Ecopetrol formed the subsidiary Ecopetrol Energía SAS E.S.P., domiciled in Colombia, whose corporate purpose is the commercialization of electric energy for the Ecopetrol Business Group. Ecopetrol has a direct participation of 99% in the capitalization of the new subsidiary, and indirect participation in the remaining 1% interest through Andean Chemicals Ltd.

 

- On March 2, 2018, a seepage of water and traces of crude oil occurred near the Lisama 158 well, located in the village of La Fortuna, in the Middle Magdalena Valley of Colombia. Ecopetrol activated its contingency plan to contain the spill. It is estimated that 550 barrels of crude, mixed with mud and rainwater, seeped into the streams of La Lisama and Caño Muerto. As of March 30, 2018, the Lisama 158 well was sealed and stopped flowing. Ecopetrol has ordered an investigation to determine the cause of the seepage. As of the date of this annual report, the National Environmental Licenses Agency (ANLA) has opened an investigation into the incident and the Prosecutor’s Office and other control entities may also open investigations. Besides the notice of seven constitutional actions for protection of fundamental rights. Ecopetrol is not aware of any other third party claims in connection with this incident, it cannot offer any assurance as to whether or not there will be third party actions in the future.

 

- As part of the investigations carried out by various control entities of the modernization and expansion project of Reficar the following developments in the investigations and proceedings have occurred:

 

Office of the Comptroller General (Contraloría General de la República): On February 2, 2018, the Legal Accounts Commission of the National House of Representatives of the Republic of Colombia informed Reficar that the House of Representatives decided, through Resolution No. 2713, that it would not close the General Budget, Treasury Account or the National Balance Sheet for the 2016 fiscal year, since the 2016 Financial Statements of several state entities, among them Reficar, had received a negative opinion from the Office of the Comptroller General. Pursuant to Resolution No. 2713, Colombian control entities have been ordered to initiate disciplinary, fiscal and/or penal investigations.

 

Ecopetrol is not in a position to forecast the results of these investigations; nor is it possible to evaluate the probability of any consequence that may impact the financial statements, such as additional provisions, fines or ignorance of tax deductions that affect the amounts of deferred tax assets.

(e) Standardized measure of discounted future net cash flows relating to proved oil and gas quantities and changes therein

 

The standardized measure of discounted future net cash flows related to the above proved crude oil and natural gas reserves is calculated in accordance with the requirements of ASU 2010-03. Estimated future cash inflows from production under SEC requirements are computed by applying unweighted arithmetic average of the first-day-of-the-month for oil and gas price to year-end quantities of estimated net proved reserves, with cost factors based on those at the end of each year, currently enacted tax rates and a 10% annual discount factor. In our view, the information so calculated does not provide a reliable measure of future cash flows from proved reserves, nor does it permit a realistic comparison to be made of one entity with another because the assumptions used cannot reflect the varying circumstances within each entity. In addition, a substantial but unknown proportion of future real cash flows from oil and gas production activities is expected to derive from reserves which have already been discovered, but which cannot yet be regarded as proved.

 

    2017     2016     2015  
Future cash inflows     182,114,282       140,458,230       176,865,586  
Future costs                        
Production     (70,159,534 )     (60,705,779 )     (76,363,169 )
Development     (14,860,992 )     (12,005,835 )     (16,498,118 )
Income taxes     (23,660,328 )     (15,400,000 )     (30,052,830 )
Future net cash flow     73,433,428       52,346,616       53,951,469  
10% discount factor     (22,216,583 )     (18,221,004 )     (19,117,422 )
Standardized measure of discounted net cash flows     51,216,845       34,125,612       34,834,047  

 

The following are the principal sources of change in the standardized measure of discounted net cash flows in 2017, 2016 and 2015:

 

    2017     2016     2015
