Risks Relating to Our Operations and the Infrastructure Industry

         All of our operating entities are subject to general economic and political conditions and risks relating to the markets in which we operate.

        Many industries, including the industries in which we operate, are impacted by political and economic conditions, and in particular, adverse events in financial markets, which may have a profound effect on global or local economies. Some key impacts of general financial market turmoil include contraction in credit markets resulting in a widening of credit spreads, devaluations and enhanced volatility in global equity, commodity and foreign exchange markets and a general lack of market liquidity. A slowdown in the financial markets or other key measures of the global economy or the local economies of the regions in which we operate, including, but not limited to, new home construction, employment rates, business conditions, inflation, fuel and energy costs, commodity prices, lack of available credit, the state of the financial markets, interest rates and tax rates may adversely affect our growth and profitability.

        The demand for services provided by our operating entities are, in part, dependent upon and correlated to general economic conditions and economic growth of the regions applicable to the relevant asset. Poor economic conditions or lower economic growth in a region or regions may, either directly or indirectly, reduce demand for the services provided by an asset.

        For example, a credit/liquidity crisis, such as the global crisis experienced in 2008/2009, could materially impact the cost and availability of financing and overall liquidity; the volatility of commodity output prices and currency exchange markets could materially impact revenues, profits and cash flow; volatile energy, commodity input and consumables prices and currency exchange rates could materially impact production costs; poor local or regional economic conditions could materially impact the level of traffic on our toll roads or volume of commodities transported on our rail network and/or shipped through our ports; our U.K. regulated distribution business earns connection revenues that would be negatively impacted by an economic recession and a reduction of housing starts in the U.K.; and the devaluation and volatility of global stock markets could materially impact the valuation of our units and preferred units. Any one of these factors could have a material adverse effect on our business, financial condition and results of operations. If such increased levels of volatility and market turmoil were to continue, our operations and the trading price of our units and preferred units may be further adversely impacted.

        In addition, we may be affected by political uncertainties in the U.S. and Europe, which may have global repercussions, including in markets where we currently operate or intend to expand into in the future.

         Some of our operations depend on continued strong demand for commodities, such as natural gas or minerals, for their financial performance. Material reduction in demand for these key commodities can potentially result in reduced value for assets, or in extreme cases, a stranded asset.

        Some of our operations are critically linked to the transport or production of key commodities. For example, our Australian regulated terminal operation relies on demand for coal exports, our Australian rail operation relies on demand for iron ore for steel production and our North American gas transmission operation relies on demand for natural gas and benefits from higher gas prices. While we endeavour to protect against short to medium term commodity demand risk wherever possible by structuring our contracts in a way that minimizes volume risk (e.g. minimum guaranteed volumes and 'take-or-pay' arrangements), these contract terms are finite and in some cases contracts contain termination or suspension rights for the benefit of the customer. Accordingly, a long-term and sustained downturn in the demand for or price of a key commodity linked to one of our operations may result in termination, suspension or default under a key contract, or otherwise have a material adverse impact on the financial performance or growth prospects of that particular operation, notwithstanding our efforts to maximize contractual protections.

        If a critical upstream or downstream business ceased to operate, this could materially impact our financial performance or the value of one or more of our operating businesses. In extreme cases, our infrastructure could become redundant, resulting in an inability to recover a return on or of capital and potentially triggering covenants and other terms and conditions under associated debt facilities.

         Acquisitions may subject us to additional risks and the expected benefits of our acquisitions may not materialize.

        A key part of Brookfield Infrastructure's strategy involves seeking acquisition opportunities. Acquisitions may increase the scale, scope and diversity of our operations. We depend on the diligence and skill of Brookfield's professionals to manage us, including integrating all of the acquired business' operations with our existing operations. These individuals may have difficulty managing the additional operations and may have other responsibilities within Brookfield's asset management business. If Brookfield does not effectively manage the additional operations, our existing business, financial condition and results of operations may be adversely affected.

        Acquisitions will likely involve some or all of the following risks, which could materially and adversely affect our business, financial condition or results of operations: the difficulty of integrating the acquired operations and personnel into our current operations; the ability to achieve potential synergies; potential disruption of our current operations; diversion of resources, including Brookfield's time and attention; the difficulty of managing the growth of a larger organization; the risk of entering markets in which we have little experience; the risk of becoming involved in labour, commercial or regulatory disputes or litigation related to the new enterprise; the risk of environmental or other liabilities associated with the acquired business; and the risk of a change of control resulting from an acquisition triggering rights of third parties or government agencies under contracts with, or authorizations held by the operating business being acquired. While it is our practice to conduct extensive due diligence investigations into businesses being acquired, it is possible that due diligence may fail to uncover all material risks in the business being acquired, or to identify a change of control trigger in a material contract or authorization, or that a contractual counterparty or government agency may take a different view on the interpretation of such a provision to that taken by us, thereby resulting in a dispute. The discovery of any material liabilities subsequent to an acquisition, as well as the failure of an acquisition to perform according to expectations, could have a material adverse effect on Brookfield Infrastructure's business, financial condition and results of operations. In addition, if returns are lower than anticipated from acquisitions, we may not be able to achieve growth in our distributions in line with our stated goals and the market value of our units may decline.

         We operate in a highly competitive market for acquisition opportunities.

        Our acquisition strategy is dependent to a significant extent on the ability of Brookfield to identify acquisition opportunities that are suitable for us. We face competition for acquisitions primarily from investment funds, operating companies acting as strategic buyers, construction companies, commercial and investment banks, and commercial finance companies. Many of these competitors are substantially larger and have considerably greater financial, technical and marketing resources than are available to us. Some of these competitors may also have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of acquisitions and to offer terms that we are unable or unwilling to match. Due to the capital intensive nature of infrastructure acquisitions, in order to finance acquisitions we will need to compete for equity capital from institutional investors and other equity providers, including Brookfield, and our ability to consummate acquisitions will be dependent on such capital continuing to be available. Increases in interest rates could also make it more difficult to consummate acquisitions because our competitors may have a lower cost of capital which may enable them to bid higher prices for assets. In addition, because of our affiliation with Brookfield, there is a higher risk that when we participate with Brookfield and others in joint ventures, partnerships and consortiums on acquisitions we may become subject to antitrust or competition laws that we would not be subject to if we were acting alone. These factors may create competitive disadvantages for us with respect to acquisition opportunities.

        We cannot provide any assurance that the competitive pressures we face will not have a material adverse effect on our business, financial condition and results of operations or that Brookfield will be able to identify and make acquisitions on our behalf that are consistent with our objectives or that generate attractive returns for our unitholders. We may lose acquisition opportunities if we do not match prices, structures and terms offered by competitors, if we are unable to access sources of equity or obtain indebtedness at attractive rates or if we become subject to antitrust or competition laws. Alternatively, we may experience decreased rates of return and increased risks of loss if we match prices, structures and terms offered by competitors.

         We may be unable to identify and complete acquisitions as planned.

        Our acquisitions are subject to a number of closing conditions, including, as applicable, securityholder approval, regulatory approval (including competition authorities) and other third party consents and approvals that are beyond our control and may not be satisfied. In particular, many jurisdictions in which we seek to invest impose government consent requirements on investments by foreign persons. Consents and approvals may not be obtained, may be obtained subject to conditions which adversely affect anticipated returns, and/or may be delayed and delay or ultimately preclude the completion of acquisitions. Government policies and attitudes in relation to foreign investment may change, making it more difficult to complete acquisitions in such jurisdictions. Furthermore, interested stakeholders could take legal steps to prevent an acquisition from being completed. If all or some of our acquisitions are unable to be completed on the terms agreed, we may need to modify or delay certain acquisitions or terminate these acquisitions altogether, the market value of our units may significantly decline and we may not be able to achieve the expected benefits of the acquisitions. For example, our previously announced acquisition of NTS is subject to a number of conditions, including the finalization, to the satisfaction of the relevant Petrobras and consortium parties, of terms and conditions of a number of long-term agreements relating to the operation of the business and other customary conditions, including regulatory approvals, some of which are beyond our control and may not be satisfied. In addition, the NTS Acquisition may be blocked or modified by regulators or pursuant to litigation. If the NTS Acquisition is unable to be completed on the terms agreed, or is blocked or modified by regulators pursuant to litigation, we may need to delay or modify the transaction or terminate it altogether. In addition, if we are not able to complete the NTS Acquisition, we may not be able to identify alternative investments that are of a comparable quality to the NTS Acquisition in a timely manner, or at all.

         Infrastructure assets may be subject to competition risk.

        Some assets may be affected by the existence of other competing assets owned and operated by other parties. There can be no assurance that our businesses can renew all their existing contracts or win additional contracts with their existing or potential customers. The ability of our businesses to maintain or improve their revenue is dependent on price, availability and customer service as well as on the availability of access to alternative infrastructure. In the case where the relevant business is unable to retain customers and/or unable to win additional customers to replace those customers it is unable to retain, the revenue from such assets will be reduced.

         Investments in infrastructure projects prior to or during a construction or expansion phase are likely to be subject to increased risk.

        A key part of our growth strategy involves identifying and taking advantage of organic growth opportunities within our existing businesses. These opportunities typically involve development and construction of new infrastructure or expansion or upgrades to existing infrastructure. Investments in new infrastructure projects during a development or construction phase are likely to be subject to additional risk that the project will not receive all required approvals, will not be completed within budget, within the agreed timeframe and to the agreed specifications and, where applicable, will not be successfully integrated into the existing assets. During the construction phase, major risks include: (i) a delay in the projected completion of the project, which can result in an increase in total project construction costs through higher capitalized interest charges and additional labour, material expenses, and a resultant delay in the commencement of cash flow; (ii) the insolvency of the head contractor, a major subcontractor and/or a key equipment supplier; (iii) construction costs exceeding estimates for various reasons, including inaccurate engineering and planning, labour and building material costs in excess of expectations and unanticipated problems with project start-up; and (iv) defects in design, engineering or construction (including, without limitation, latent defects that do not materialize during an applicable warranty or limitation periods). Such unexpected increases may result in increased debt service costs, operations and maintenance expenses and damage payments for late delivery. This may result in the inability of project owners to meet the higher interest and principal repayments arising from the additional debt required.

        In addition, construction projects may be exposed to significant liquidated damages to the extent that commercial operations are delayed beyond prescribed dates or that performance levels do not meet guaranteed levels. For example, a liquidated damages regime applies in respect of some of the expansion of works at our Brazilian toll road business.

        We currently have approximately $1.4 billion of committed backlog. Total capital to be commissioned in the next two to three years currently stands at approximately $2.4 billion. We can provide no assurance that we will be able to complete these projects on time or within budget. In addition, we are pursuing a number of other organic growth opportunities that are not yet committed. Accordingly, we can provide no assurance that these projects will materialize on the terms currently contemplated, or at all.

         We are subject to foreign currency risk and our risk management activities may adversely affect the performance of our operations.

        A significant portion of our current operations are in countries where the U.S. dollar is not the functional currency. These operations pay distributions in currencies other than the U.S. dollar, which we must convert to U.S. dollars prior to making distributions, and certain of our operations have revenues denominated in currencies different from our expense structure, thus exposing us to currency risk. Fluctuations in currency exchange rates could reduce the value of cash flows generated by our operating entities or could make it more expensive for our customers to purchase our services and consequently reduce the demand for our services. In addition, a significant depreciation in the value of such foreign currencies may have a material adverse effect on our business, financial condition and results of operations.

        When managing our exposure to such market risks, we may use forward contracts, options, swaps, caps, collars and floors or pursue other strategies or use other forms of derivative instruments. The success of any hedging or other derivative transactions that we enter into generally will depend on our ability to structure contracts that appropriately offset our risk position. As a result, while we may enter into such transactions in order to reduce our exposure to market risks, unanticipated market changes may result in poorer overall investment performance than if the derivative transaction had not been executed. Such transactions may also limit the opportunity for gain if the value of a hedged position increases.

         General economic and business conditions that impact the debt or equity markets could impact our ability to access credit markets.

        General economic and business conditions that impact the debt or equity markets could impact the availability of credit to, and cost of credit for, Brookfield Infrastructure. We have revolving credit facilities and other short-term borrowings. The amount of interest charged on these will fluctuate based on changes in short-term interest rates. Any economic event that affects interest rates or the ability to refinance borrowings could materially adversely impact our financial condition. Movements in interest rates could also affect the discount rates used to value our assets, which in turn could cause their valuations calculated under IFRS to be reduced resulting in a material reduction in our equity value.

        In addition, some of our operations either currently have a credit rating or may have a credit rating in the future. A credit rating downgrade may result in an increase in the cost of debt for the relevant businesses and reduced access to debt markets.

        Some assets in our portfolio have a requirement for significant capital expenditure. For other assets, cash, cash equivalents and short-term investments combined with cash flow generated from operations are believed to be sufficient for it to make the foreseeable required level of capital investment. However, no assurance can be given that additional capital investments will not be required in these businesses. If we are unable to generate enough cash to finance necessary capital expenditures through operating cash flow, then we may be required to issue additional equity or incur additional indebtedness. The issue of additional equity would be dilutive to existing unitholders at the time. Any additional indebtedness would increase our leverage and debt payment obligations, and may negatively impact its business, financial condition and results of operations.

        Our business relies on continued access to capital to fund new investments and capital projects. While we aim to prudently manage our capital requirements and ensure access to capital is always available, it is possible we may overcommit ourselves or misjudge the requirement for capital or the availability of liquidity. Such a misjudgment may require capital to be raised quickly and the inability to do so could result in negative financial consequences or in extreme cases bankruptcy.

Brookfield Infrastructure 15

Table of Contents

         All of our operating entities are subject to changes in government policy and legislation.

        Our financial condition and results of operations could also be affected by changes in economic or other government policies or other political or economic developments in each country or region, as well as regulatory changes or administrative practices over which we have no control such as: the regulatory environment related to our business operations, concession agreements and periodic regulatory resets; interest rates; currency fluctuations; exchange controls and restrictions; inflation; liquidity of domestic financial and capital markets; policies relating to climate change or policies relating to tax; and other political, social, economic, and environmental and occupational health and safety developments that may occur in or affect the countries in which our operating entities are located or conduct business or the countries in which the customers of our operating entities are located or conduct business or both.

        In addition, operating costs can be influenced by a wide range of factors, many of which may not be under the control of the owner/operator, including the need to comply with the directives of central and local government authorities. For example, in the case of our utility, transport and energy operations, we cannot predict the impact of future economic conditions, energy conservation measures, alternative fuel requirements, or governmental regulation all of which could reduce the demand for or availability of commodities our transport and energy operations rely upon, most notably coal and natural gas. It is difficult to predict government policies and what form of laws and regulations will be adopted or how they will be construed by the relevant courts, or to the extent which any changes may adversely affect us.

         We may be exposed to natural disasters, weather events, uninsurable losses and force majeure events.

        Force majeure is the term generally used to refer to an event beyond the control of the party claiming that the event has occurred, including but not limited to acts of God, fires, floods, earthquakes, wars and labour strikes. The assets of our infrastructure businesses are exposed to unplanned interruptions caused by significant catastrophic events such as cyclones, landslides, explosions, terrorist attacks, war, floods, earthquakes, fires, major plant breakdowns, pipeline or electricity line ruptures, accidents, extreme weather events or other disasters. Operational disruption, as well as supply disruption, could adversely affect the cash flow available from these assets. In addition, the cost of repairing or replacing damaged assets could be considerable and could give rise to third-party claims. In some cases, project agreements can be terminated if the force majeure event is so catastrophic as to render it incapable of remedy within a reasonable time period. Repeated or prolonged interruption may result in a permanent loss of customers, substantial litigation, damage, or penalties for regulatory or contractual non-compliance. Moreover, any loss from such events may not be recoverable in whole or in part under relevant insurance policies. Business interruption insurance is not always available, or available on reasonable economic terms to protect the business from these risks.

        Given the nature of the assets operated by our operating entities, we may be more exposed to risks in the insurance market that lead to limitations on coverage and/or increases in premium. For example, many components of our South American electricity transmission operations and toll roads are not insured or not fully insured against losses from earthquakes and our North American gas transmission operation, our Australian distribution operations and our European regulated distribution operations self-insure the majority of their line and pipe assets. Therefore, the occurrence of a major or uninsurable event could have a material adverse effect on financial performance. Even if such insurance were available, the cost may be prohibitive. The ability of the operating entities to obtain the required insurance coverage at a competitive price may have an impact on the returns generated by them and accordingly the returns we receive.

        For example, our regulated energy distribution businesses generate revenue based on the volume transmitted through their systems. Weather that deviates materially from normal conditions could impact these businesses. A number of our businesses may be adversely impacted by extreme weather. Our Australian rail operation transports grain on its system, for which it is contracted on a volume basis. A drought could have a material negative impact on revenue from grain transportation.

         All of our infrastructure operations may require substantial capital expenditures in the future.

        Our utilities, transport and energy operations are capital intensive and require substantial ongoing expenditures for, among other things, additions and improvements, and maintenance and repair of plant and equipment related to our operations. Any failure to make necessary capital expenditures to maintain our operations in the future could impair the ability of our operations to serve existing customers or accommodate increased volumes. In addition, we may not be able to recover such investments based upon the rates our operations are able to charge.

        In some of the jurisdictions in which we have utilities, transport or energy operations, certain maintenance capital expenditures may not be covered by the regulatory framework. If our operations in these jurisdictions require significant capital expenditures to maintain our asset base, we may not be able to recover such costs through the regulatory framework. In addition, we may be exposed to disallowance risk in other jurisdictions to the extent that capital expenditures and other costs are not fully recovered through the regulatory framework.

         Performance of our operating entities may be harmed by future labour disruptions and economically unfavourable collective bargaining agreements.

        Several of our current operations or other business operations have workforces that are unionized or that in the future may become unionized and, as a result, are required to negotiate the wages, benefits and other terms with many of their employees collectively. If an operating entity were unable to negotiate acceptable contracts with any of its unions as existing agreements expire, it could experience a significant disruption of its operations, higher ongoing labour costs and restrictions on its ability to maximize the efficiency of its operations, which could have a material adverse effect on its business, financial condition and results of operations.

        In addition, in some jurisdictions where we have operations, labour forces have a legal right to strike which may have an impact on our operations, either directly or indirectly, for example if a critical upstream or downstream counterparty was itself subject to a labour disruption which impacted our ability to operate.

         Our operations are exposed to occupational health and safety and accident risks.

        Infrastructure projects and operational assets are highly exposed to the risk of accidents that may give rise to personal injury, loss of life, disruption to service and economic loss. Some of the tasks undertaken by employees and contractors are inherently dangerous and have the potential to result in serious injury or death.

        Our operating entities are subject to laws and regulations governing health and safety matters, protecting both members of the public and their employees and contractors. Occupational health and safety legislation and regulations differ in each jurisdiction. Any breach of these obligations, or serious accidents involving our employees, contractors or members of the public could expose them to adverse regulatory consequences, including the forfeit or suspension of operating licenses, potential litigation, claims for material financial compensation, reputational damage, fines or other legislative sanction, all of which have the potential to impact the results of our operating entities and our ability to make distributions. Furthermore, where we do not control a business, we have a limited ability to influence health and safety practices and outcomes.

Brookfield Infrastructure 17

Table of Contents

         Many of our operations are subject to economic regulation and may be exposed to adverse regulatory decisions.

        Due to the essential nature of some of the services provided by our assets and the fact that some of these services are provided on a monopoly or near monopoly basis, many of our operations are subject to forms of economic regulation. This regulation can involve different forms of price control and can involve ongoing commitments to economic regulators and other governmental agencies. The terms upon which access to our facilities is provided, including price, can be determined or amended by a regulator periodically. Future terms to apply, including access charges that our operations are entitled to charge, cannot be determined with any certainty, as we do not have discretion as to the amount that can be charged. New legislation, regulatory determinations or changes in regulatory approaches may result in regulation of previously unregulated businesses or material changes to the revenue or profitability of our operations. In addition, a decision by a government or regulator to regulate non-regulated assets may significantly and negatively change the economics of these businesses and the value or financial performance of Brookfield Infrastructure. For example, in 2010 regulatory action taken by the Federal Energy Regulatory Commission ("FERC") saw a significant reduction in annual cashflow expectations of our North American gas transmission operations. Similarly, in 2016 a periodic regulatory reset at our Australian coal terminal resulted in a decline in annual cashflows at that business.

         Our operating entities are exposed to the risk of environmental damage.

        Many of Brookfield Infrastructure's assets are involved in using, handling or transporting substances that are toxic, combustible or otherwise hazardous to the environment. Furthermore, some of our assets have operations in or in close proximity to environmentally sensitive areas or densely populated communities. There is a risk of a leak, spillage or other environmental emission at one of these assets, which could cause regulatory infractions, damage to the environment, injury or loss of life. Such an incident if it occurred could result in fines or penalties imposed by regulatory authorities, revocation of licenses or permits required to operate the business or the imposition of more stringent conditions in those licenses or permits, or legal claims for compensation (including punitive damages) by affected stakeholders. In addition, some of our assets may be subject to regulations or rulings made by environmental agencies that conflict with existing obligations we have under concession or other permitting agreements. Resolution of such conflicts may lead to uncertainty and increased risk of delays or cost over-runs on projects. All of these have the potential to significantly impact the value or financial performance of Brookfield Infrastructure.

         Our operating entities are exposed to the risk of increasing environmental legislation and the broader impacts of climate change.

        With an increasing global focus and public sensitivity to environmental sustainability and environmental regulation becoming more stringent, Brookfield Infrastructure's assets could be subject to increasing environmental responsibility and liability. For example, many jurisdictions in which Brookfield Infrastructure operates are considering implementing, or have implemented, schemes relating to the regulation of carbon emissions. As a result, there is a risk that the consumer demand for some of the energy sources supplied by Brookfield Infrastructure will be reduced. For example, the United Kingdom's phasing out of analog meters and use of gas as a source of heating for residential customers could lead to a reduction in revenue and growth at our U.K. utility business. The nature and extent of future regulation in the various jurisdictions in which Brookfield Infrastructure's operations are situated is uncertain, but is expected to become more complex and stringent.

18 Brookfield Infrastructure

Table of Contents

        It is difficult to assess the impact of any such changes on Brookfield Infrastructure. These schemes may result in increased costs to our operations that may not be able to be passed onto our customers and may have an adverse impact on prospects for growth of some businesses. To the extent such regimes (such as carbon emissions schemes or other carbon emissions regulations) become applicable to the operations of Brookfield Infrastructure (and the costs of such regulations are not able to be fully passed on to consumers), its financial performance may be impacted due to costs applied to carbon emissions and increased compliance costs.

        Our operating entities are also subject to laws and regulations relating to the protection of the environment and pollution. Standards are set by these laws and regulations regarding certain aspects of environmental quality and reporting, provide for penalties and other liabilities for the violation of such standards, and establish, in certain circumstances, obligations to remediate and rehabilitate current and former facilities and locations where our operations are, or were, conducted. These laws and regulations may have a detrimental impact on the financial performance of our infrastructure operations and projects through increased compliance costs or otherwise. Any breach of these obligations, or even incidents relating to the environment that do not amount to a breach, could adversely affect the results of our operating entities and their reputations and expose them to claims for financial compensation or adverse regulatory consequences.

        Our operations may also be exposed directly or indirectly to the broader impacts of climate change, including extreme weather events, export constraints on commodities, increased resource prices and restrictions on energy and water usage.

         Our operating entities may be exposed to higher levels of regulation than in other sectors and breaches of such regulations could expose our operating entities to claims for financial compensation and adverse regulatory consequences.

        In many instances, our ownership and operation of infrastructure assets involves an ongoing commitment to a governmental agency. The nature of these commitments exposes the owners of infrastructure assets to a higher level of regulatory control than typically imposed on other businesses. For example, several of our utilities, transport and energy operations are subject to government safety and reliability regulations that are specific to their industries. The risk that a governmental agency will repeal, amend, enact or promulgate a new law or regulation or that a governmental authority will issue a new interpretation of the law or regulations, could affect our operating entities substantially.

        Sometimes commitments to governmental agencies, for example, under toll road concession arrangements, involve the posting of financial security for performance of obligations. If obligations are breached these financial securities may be called upon by the relevant agency.

        There is also the risk that our operating entities do not have, might not obtain, or may lose permits necessary for their operations. Permits or special rulings may be required on taxation, financial and regulatory related issues. Even though most permits and licenses are obtained before the commencement of operations, many of these licenses and permits have to be renewed or maintained over the life of the business. The conditions and costs of these permits, licenses and consents may be changed on any renewal, or, in some cases, may not be renewed due to unforeseen circumstances or a subsequent change in regulations. In any event, the renewal or non-renewal could have a material adverse effect on our business, financial condition and results of operations.

        The risk that a government will repeal, amend, enact or promulgate a new law or regulation or that a regulator or other government agency will issue a new interpretation of the law or regulations, may affect our operations or a project substantially. This may also be due to court decisions and actions of government agencies that affect these operations or a project's performance or the demand for its services. For example, a government policy decision may result in adverse financial outcomes for us through directions to spend money to improve security, safety, reliability or quality of service.

Brookfield Infrastructure 19

Table of Contents

         The lands used for our infrastructure assets may be subject to adverse claims or governmental or First Nations rights.

        Our operations require large areas of land on which to be constructed and operated. The rights to use the land can be obtained through freehold title, leases and other rights of use. Although we believe that we have valid rights to all material easements, licenses and rights of way for our infrastructure operations, not all of our easements, licenses and rights of way are registered against the lands to which they relate and may not bind subsequent owners. Additionally, different jurisdictions have adopted different systems of land title and in some jurisdictions it may not be possible to ascertain definitively who has the legal right to enter into land tenure arrangements with the asset owner. In some jurisdictions where we have operations, it is possible to claim indigenous or aboriginal rights to land and the existence or declaration of native title may affect the existing or future activities of our utilities, transport or energy operations and impact on their business, financial condition and results of operations.

        In addition, a government, court, regulator, or indigenous or aboriginal group may make a decision or take action that affects an asset or project's performance or the demand for its services. In particular, a regulator may restrict our access to an asset, or may require us to provide third parties with access, or may affect the pricing structure so as to lower our revenues and earnings. In Australia, native title legislation provides for a series of procedures that may need to be complied with if native title is declared on relevant land. In Canada, for example, courts have recognized that First Nations peoples may possess rights at law in respect of land used or occupied by their ancestors where treaties have not been concluded to deal with these rights. In either case, the claims of a First Nations group may affect the existing or future activities of our operations, impact on our business, financial condition and results of operations, or require that compensation be paid.

         Some of our transactions and current operations are structured as joint ventures, partnerships and consortium arrangements, and we intend to continue to operate in this manner in the future, which may reduce Brookfield's and our influence over our operations and may subject us to additional obligations.

        Some of our transactions and current operations are structured as joint ventures, partnerships and consortium arrangements. An integral part of our strategy is to participate with institutional investors in Brookfield-sponsored or co-sponsored consortiums for single asset acquisitions and as a partner in or alongside Brookfield-sponsored or co-sponsored partnerships that target acquisitions that suit our profile. These arrangements are driven by the magnitude of capital required to complete acquisitions of infrastructure assets and other industry-wide trends that we believe will continue. Such arrangements involve risks not present where a third party is not involved, including the possibility that partners or co-venturers might become bankrupt or otherwise fail to fund their share of required capital contributions. Additionally, partners or co-venturers might at any time have economic or other business interests or goals different from us and Brookfield.

20 Brookfield Infrastructure

Table of Contents

        Joint ventures, partnerships and consortium investments may provide for a reduced level of influence over an acquired company because governance rights are shared with others. Accordingly, decisions relating to the underlying operations, including decisions relating to the management and operation and the timing and nature of any exit, will be made by a majority or supermajority vote of the investors or by separate agreements that are reached with respect to individual decisions. For example, when we participate with institutional investors in Brookfield-sponsored or co-sponsored consortiums for asset acquisitions and as a partner in or alongside Brookfield-sponsored or co-sponsored partnerships, there is often a finite term to the investment or a date after which partners are granted liquidity rights, which could lead to the investment being sold prior to the date we would otherwise choose. In addition, such operations may be subject to the risk that the company may make business, financial or management decisions with which we do not agree or the management of the company may take risks or otherwise act in a manner that does not serve our interests. Because we may have a reduced level of influence over such operations, we may not be able to realize some or all of the benefits that we believe will be created from our and Brookfield's involvement. If any of the foregoing were to occur, our business, financial condition and results of operations could suffer as a result.

        In addition, because some of our transactions and current operations are structured as joint ventures, partnerships or consortium arrangements, the sale or transfer of interests in some of our operations are or may be subject to rights of first refusal or first offer, tag along rights or drag along rights and some agreements provide for buy-sell or similar arrangements. For example, some of our investments are subject to a shareholder agreement which allows for the sale of the assets without our consent. Such rights may be triggered at a time when we may not want them to be exercised and such rights may inhibit our ability to sell our interest in an entity within our desired time frame or on any other desired basis.

         Our infrastructure business is at risk of becoming involved in disputes and possible litigation.

        Our infrastructure business is at risk of becoming involved in disputes and possible litigation, the extent of which cannot be ascertained. Any material or costly dispute or litigation could adversely affect the value of the assets or future financial performance of Brookfield Infrastructure. In addition, as a result of the actions of the Holding Entities or the operating entities, Brookfield Infrastructure could be subject to various legal proceedings concerning disputes of a commercial nature, or to claims in the event of bodily injury or material damage. The final outcome of any proceeding could have a negative impact on the business, financial condition or results of operations of Brookfield Infrastructure during a given quarter or financial year.

         Some of our businesses operate in jurisdictions with less developed legal systems and could experience potential difficulties in obtaining effective legal redress and create uncertainties.

        Some of our businesses operate in jurisdictions with less developed legal systems than those in more established economies. In these jurisdictions, Brookfield Infrastructure could be faced with potential difficulties in obtaining effective legal redress; a higher degree of discretion on the part of governmental authorities; a lack of judicial or administrative guidance on interpreting applicable rules and regulations; inconsistencies or conflicts between and within various laws, regulations, decrees, orders and resolutions; and relative inexperience of the judiciary and courts in such matters.

Table of Contents

        In addition, in certain jurisdictions, Brookfield Infrastructure may find that the commitment of local business people, government officials and agencies and the judicial system to abide by legal requirements and negotiated agreements could be uncertain, creating particular concerns with respect to permits, approvals and licenses required or desirable for, or agreements entered into in connection with, the Brookfield Infrastructure business in any such jurisdiction. These may be susceptible to revision or cancellation and legal redress may be uncertain or delayed. There can be no assurance that joint ventures, licenses, permits or approvals (or applications for licenses, permits or approvals) or other legal arrangements will not be adversely affected by the actions of government authorities or others and the effectiveness of and enforcement of such arrangements in these jurisdictions cannot be assured.

         Action taken by national, state or provincial governments, including nationalization or the imposition of new taxes, could materially impact the financial performance or value of our assets.

        Our assets are located in many different jurisdictions, each with its own government and legal system. Different levels of political risk exist in each jurisdiction and it is possible that action taken by a national, state or provincial government, including the nationalization of a business or the imposition of new taxes, could materially impact our financial performance or in extreme cases deprive Brookfield Infrastructure of one or more of its businesses without adequate compensation.

         Our business relies on the use of technology, and as a result, we may be exposed to cyber-security attacks.

        Our business places significant reliance on information and other technology. This technology includes our computer systems used for information, processing, administrative and commercial operations and the operating plant and equipment used by our assets, including that on our toll roads, in our electricity transmission systems, coal terminal operations, ports, rail networks, and by our electricity and gas distribution companies. In addition, our business also relies upon telecommunication services to interface with its widely distributed business network and customers. The information and embedded systems of key business partners and regulatory agencies are also important to our operations. Our business relies on this technology functioning as intended.

        Our computer systems may be subject to cybersecurity risks or other breaches of information technology security, noting the increasing frequency and severity of these kinds of incidents. Further, the operating equipment used by our assets may not continue to perform as it has in the past, and there is a risk of equipment failure due to wear and tear, latent defect, design or operator errors or early obsolescence, among other things.

        A breach of our cyber/data security measures, the failure of any such computerized system or of the operating equipment used by our assets for a significant time period could have a material adverse effect on our business prospects, financial condition, results of operations and cash flow and it may not be possible to recover losses suffered from such incidents under our insurance policies. Although we are continuing to develop defenses to such attacks, we can provide no assurance they will be successful in preventing or ameliorating damage from such an attack on us and, as the manner in which cyber-attacks are undertaken has become more sophisticated, there is a risk that the occurrence of cyber-attack may remain undetected for an extended period.

        Furthermore, our communications infrastructure operations rely for their continued viability on the ongoing demand for tower infrastructure, which is uncertain and could be subject to bypass risk or obsolescence as a result of new or developing technologies.

         Many of our operations depend on relevant contractual arrangements.

        Many of our operations rely on revenue from customers under contracts. There is a risk that customers will default under these contracts. We cannot provide assurance that one or more customers will not default on their obligations to us or that such a default or defaults will not have a material adverse effect on our operations, financial position, future results of operations, or future cash flows. Furthermore, the bankruptcy of one or more of our customers, or some other similar proceeding or liquidity constraint, might make it unlikely that we would be able to collect all or a significant portion of amounts owed by the distressed entity or entities. In addition, such events might force such customers to reduce or curtail their future use of our products and services, which could have a material adverse effect on our business, financial condition and results of operations. For example, we have a single customer which represented a majority of contractual and regulated revenues of our South American electricity transmission operations in 2014. As this accounts for a majority of its cash flow, our South American electricity transmission operations could be materially adversely affected by any material change in the financial condition of that customer. Similarly, our rail business is party to several commercial track access agreements to provide access to our rail network for the haulage of iron ore. The largest of these contracts currently accounts for a significant portion of forecast Adjusted EBITDA within the rail business and an event of default under this contract could have a materially adverse effect on that business.

        We endeavour to minimize risk wherever possible by structuring our contracts in a way that minimizes volume risk (e.g. minimum guaranteed volumes and 'take-or-pay' arrangements), however it is possible that the take-or-pay arrangements may not be fully effective. In addition, the contract terms are finite and in some cases the contracts contain termination or suspension rights for the benefit of the customer.

        Certain of our assets with revenues contracted under contracts will be subject to re-contracting risk in the future. We cannot provide assurance that we will be able to re-negotiate these contracts once their terms expire, or that even if we are able to do so, that we will be able to obtain the same prices or terms we currently receive. If we are unable to renegotiate these contracts, or unable to receive prices at least equal to the current prices we receive, our business, financial condition, results of operation and prospects could be adversely affected.

         We rely on tolling and revenue collection systems.

        Revenues at some of our assets depend on reliable and efficient tolling, metering or other revenue collection systems. There is a risk that, if one or more of our businesses are not able to operate and maintain these tolling, metering or other revenue collection systems in the manner expected, or if the cost of operation and maintenance is greater than expected, our assets, business, financial condition, and risks of operations could be materially adversely affected. Users of our facilities who do not pay tolls or other charges may be subject to either direct legal action from the relevant business, or in some cases may be referred to the state for enforcement action. We bear the ultimate risk if enforcement actions against defaulting customers are not successful or if enforcement actions are more costly or take more time than expected.

         Our ability to finance our operations is subject to various risks relating to the state of the capital markets.

        Our financing strategy involves both the issuance of partnership level equity and the issuance of corporate debt. For example, in December 2016, we issued approximately 15.6 million units at $32 per unit in the United States and Canada, together with 8,139,000 additional Redeemable Partnership Units to Brookfield in a concurrent private placement, and in August 2016, we raised C$250 million of gross proceeds through the issuance of Series 5 Preferred Units in Canada.

Brookfield Infrastructure 23

Table of Contents

        We have corporate debt and limited recourse project level debt, the majority of which is non-recourse that will need to be replaced from time to time. Our financings may contain conditions that limit our ability to repay indebtedness prior to maturity without incurring penalties, which may limit our capital markets flexibility. Refinancing risk includes, among other factors, dependence on continued operating performance of our assets, future electricity market prices, future capital markets conditions, the level of future interest rates and investors' assessment of our credit risk at such time. In addition, certain of our financings are, and future financings may be exposed to floating interest rate risks, and if interest rates increase, an increased proportion of our cash flow may be required to service indebtedness. Future acquisitions, development and construction of new facilities and other capital expenditures will be financed out of cash generated from our operations, borrowings and possible future sales of equity. Our ability to obtain financing to finance our growth is dependent on, among other factors, the overall state of the capital markets, continued operating performance of our assets, future electricity market prices, the level of future interest rates and investors' assessment of our credit risk at such time, and investor appetite for investments in renewable energy and infrastructure assets in general and in our securities in particular. To the extent that external sources of capital become limited or unavailable or available on onerous terms, our ability to make necessary capital investments to construct new or maintain existing facilities will be impaired, and as a result, our business, financial condition, results of operations and prospects may be materially adversely affected.

         Changes in our credit ratings may have an adverse effect on our financial position and ability to raise capital.

        We cannot assure you that any credit rating assigned to us or any of our subsidiaries' debt securities will remain in effect for any given period of time or that any rating will not be lowered or withdrawn entirely by the relevant rating agency. A lowering or withdrawal of such ratings may have an adverse effect on our financial position and ability to raise capital.

         We may suffer a significant loss resulting from fraud, bribery, corruption other illegal acts, inadequate or failed internal processes or systems, or from external events.

        We may suffer a significant loss resulting from fraud, bribery, corruption, other illegal acts by our employees or those of Brookfield, inadequate or failed internal processes or systems, or from external events, such as security threats affecting our ability to operate. Both Brookfield and our partnership operate in different markets and rely on our employees to follow our policies and processes as well as applicable laws in their activities. Risk of illegal acts or failed systems is managed through our infrastructure, controls, systems and people, complemented by a focus on enterprise-wide management of specific operational risks such as fraud, bribery and corruption, as well as personnel and systems risks. Specific programs, policies, standards and methodologies have been developed to support the management of these risks, however these cannot guarantee that such conduct does not occur and if it does, it can result in direct or indirect financial loss, reputational impact or regulatory consequences.

Risks Relating to Our Relationship with Brookfield

         Brookfield exercises substantial influence over our partnership and we are highly dependent on the Service Provider.

        Brookfield is the sole shareholder of our General Partner. As a result of its ownership of our General Partner, Brookfield is able to control the appointment and removal of our General Partner's directors and, accordingly, exercise substantial influence over our partnership and over the Holding LP, for which our partnership is the managing general partner. Our partnership and the Holding LP do not have any employees and depend on the management and administration services provided by the Service Provider. Brookfield personnel and support staff that provide services to us are not required to have as their primary responsibility the management and administration of our partnership or the Holding LP or to act exclusively for either of us. Any failure to effectively manage our current operations or to implement our strategy could have a material adverse effect on our business, financial condition and results of operations.

         Brookfield has no obligation to source acquisition opportunities for us and we may not have access to all infrastructure acquisitions that Brookfield identifies.

        Our ability to grow depends on Brookfield's ability to identify and present us with acquisition opportunities. Brookfield established our partnership to own and operate certain infrastructure assets on a global basis. However, Brookfield has no obligation to source acquisition opportunities for us. In addition, Brookfield has not agreed to commit to us any minimum level of dedicated resources for the pursuit of infrastructure-related acquisitions. There are a number of factors which could materially and adversely impact the extent to which suitable acquisition opportunities are made available from Brookfield, for example:

•

there is no accepted industry standard for what constitutes an infrastructure asset. For example, Brookfield may consider certain assets that have both real-estate related characteristics and infrastructure related characteristics to be real estate and not infrastructure;



•

it is an integral part of Brookfield's (and our) strategy to pursue the acquisition of infrastructure assets through consortium arrangements with institutional investors, strategic partners or financial sponsors and to form partnerships to pursue such acquisitions on a specialized or global basis. Although Brookfield has agreed with us that it will not enter any such arrangements that are suitable for us without giving us an opportunity to participate in them, there is no minimum level of participation to which we will be entitled;



•

the same professionals within Brookfield's organization that are involved in acquisitions that are suitable for us are responsible for the consortiums and partnerships referred to above, as well as having other responsibilities within Brookfield's broader asset management business. Limits on the availability of such individuals will likewise result in a limitation on the availability of acquisition opportunities for us;



•

Brookfield will only recommend acquisition opportunities that it believes are suitable for us. Our focus is on assets where we believe that our operations-oriented approach can be deployed to create value. Accordingly, opportunities where Brookfield cannot play an active role in influencing the underlying operating company or managing the underlying assets may not be suitable for us, even though they may be attractive from a purely financial perspective. Legal, regulatory, tax and other commercial considerations will likewise be an important consideration in determining whether an opportunity is suitable and will limit our ability to participate in these more passive investments and may limit our ability to have more than 50% of our assets concentrated in a single jurisdiction; and

Brookfield Infrastructure 25

Table of Contents

•

in addition to structural limitations, the question of whether a particular acquisition is suitable is highly subjective and is dependent on a number of factors including our liquidity position at the time, the risk profile of the opportunity, its fit with the balance of our then current operations and other factors. If Brookfield determines that an opportunity is not suitable for us, it may still pursue such opportunity on its own behalf, or on behalf of a Brookfield-sponsored partnership or consortium.

        In making these determinations, Brookfield may be influenced by factors that result in a misalignment or conflict of interest. See Item 7.B "Related Party Transactions—Conflicts of Interest and Fiduciary Duties."

         The departure of some or all of Brookfield's professionals could prevent us from achieving our objectives.

        We depend on the diligence, skill and business contacts of Brookfield's professionals and the information and opportunities they generate during the normal course of their activities. Our future success will depend on the continued service of these individuals, who are not obligated to remain employed with Brookfield. Brookfield has experienced departures of key professionals in the past and may do so in the future, and we cannot predict the impact that any such departures will have on our ability to achieve our objectives. The departure of a significant number of Brookfield's professionals for any reason, or the failure to appoint qualified or effective successors in the event of such departures, could have a material adverse effect on our ability to achieve our objectives. Our Limited Partnership Agreement and our Master Services Agreement do not require Brookfield to maintain the employment of any of its professionals or to cause any particular professionals to provide services to us or on our behalf.

         The control of our General Partner may be transferred to a third party without unitholder or preferred unitholder consent.

        Our General Partner may transfer its general partnership interest to a third party in a merger or consolidation or in a transfer of all or substantially all of its assets without the consent of our unitholders or preferred unitholders. Furthermore, at any time, the shareholder of our General Partner may sell or transfer all or part of its shares in our General Partner without the approval of our unitholders or preferred unitholders. If a new owner were to acquire ownership of our General Partner and to appoint new directors or officers of its own choosing, it would be able to exercise substantial influence over our partnership's policies and procedures and exercise substantial influence over our management and the types of acquisitions that we make. Such changes could result in our partnership's capital being used to make acquisitions in which Brookfield has no involvement or in making acquisitions that are substantially different from our targeted acquisitions. Additionally, our partnership cannot predict with any certainty the effect that any transfer in the ownership of our General Partner would have on the trading price of our units and preferred units or our partnership's ability to raise capital or make investments in the future, because such matters would depend to a large extent on the identity of the new owner and the new owner's intentions with regard to our partnership. As a result, the future of our partnership would be uncertain and our partnership's business, financial condition and results of operations may suffer.

Table of Contents

         Brookfield's ownership position of our partnership and the Holding LP entitles it to a significant percentage of our distributions, and Brookfield may increase its ownership relative to other unitholders.

        Brookfield beneficially owns, directly or indirectly, approximately 29.5% of our units on a fully-exchanged basis, substantially all of which consists of 108,401,992 Redeemable Partnership Units of the Holding LP that are redeemable for cash or exchangeable for our units in accordance with the Redemption-Exchange Mechanism. See Item 10.B "Memorandum and Articles of Association—Description of the Holding LP's Limited Partnership Agreement—Redemption-Exchange Mechanism." In addition, Brookfield owns approximately 0.4% of the Holding LP through Special Limited Partner Units, which entitle Brookfield to receive distributions in proportion to its special limited partnership interest, plus additional incentive distributions, as described in Item 7.B "Related Party Transactions—Special Limited Partner Distributions" and "—Incentive Distributions." Accordingly, Brookfield's ownership position of Redeemable Partnership Units and Special Limited Partner Units allows Brookfield to receive a substantial percentage of our distributions. See Item 10.B "Memorandum and Articles of Association."

        Brookfield may increase its ownership position in our partnership and the Holding LP. Under the distribution reinvestment plan of the Holding LP, Brookfield can reinvest distributions on its Redeemable Partnership Units for additional Redeemable Partnership Units. In addition, Brookfield may also elect to reinvest incentive distributions from its Special Limited Partner Units in exchange for additional Redeemable Partnership Units. Brookfield has advised us that it may from time to time reinvest these distributions for such additional Redeemable Partnership Units, which would increase its beneficial ownership percentage of our units and increase its share of distributions relative to public unitholders. To date, Brookfield has not elected to reinvest any of the distributions from its Redeemable Partnership Units or its Special Limited Partner Units for additional Redeemable Partnership Units, but it may elect to do so in the future.

        Brookfield may also purchase additional units of our partnership in the open market or pursuant to private placement. Brookfield historically has purchased additional Redeemable Partnership Units in private placements concurrent with public offerings of our units. Most recently, it purchased 8,139,000 Redeemable Partnership Units in connection with our December 2016 offering. See Item 5.B "Liquidity and Capital Resources—Partnership Capital."

        Any of these events may result in Brookfield increasing its ownership of our units relative to other unitholders, which could reduce the amount of cash available for distribution to public unitholders.

         Our Master Services Agreement and our other arrangements with Brookfield do not impose on Brookfield any fiduciary duties to act in the best interests of our unitholders or preferred unitholders.

        Our Master Services Agreement and our other arrangements with Brookfield do not impose on Brookfield any duty (statutory or otherwise) to act in the best interests of the Service Recipients, nor do they impose other duties that are fiduciary in nature. As a result, our General Partner, a wholly-owned subsidiary of Brookfield Asset Management, in its capacity as our General Partner, has sole authority to enforce the terms of such agreements and to consent to any waiver, modification or amendment of their provisions, subject to approval by a majority of our independent directors in accordance with our conflicts protocol.

Brookfield Infrastructure 27

Table of Contents

        In addition, the Bermuda Limited Partnership Act of 1883 ("Bermuda Limited Partnership Act"), under which our partnership and the Holding LP were established, does not impose statutory fiduciary duties on a general partner of a limited partnership in the same manner that certain corporate statutes, such as the Canada Business Corporations Act ("Canada Business Corporations Act"), impose fiduciary duties on directors of a corporation. In general, under applicable Bermudian legislation, a general partner has a duty to: (i) act at all times in good faith; and (ii) subject to any express provisions of the partnership agreement to the contrary, act in the interests of the limited partnership. Applicable Bermuda legislation also provides that a general partner has certain limited duties to its limited partners, such as the duty to render accounts, account for private profits and not compete with the partnership in business. In addition, Bermudian common law recognizes that a general partner owes a duty of utmost good faith to its limited partners. These duties are, in most respects, similar to duties imposed on a general partner of a limited partnership under U.S. and Canadian law. However, to the extent that our General Partner owes any such fiduciary duties to our partnership, our preferred unitholders and unitholders, these duties have been modified pursuant to our Limited Partnership Agreement as a matter of contract law, with the exception of the duty of our General Partner to act in good faith, which cannot be modified. We have been advised by Bermudian counsel that such modifications are not prohibited under Bermudian law, subject to typical qualifications as to enforceability of contractual provisions, such as the application of general equitable principles. This is similar to Delaware law which expressly permits modifications to the fiduciary duties owed to partners, other than an implied contractual covenant of good faith and fair dealing.

        Our Limited Partnership Agreement contains various provisions that modify the fiduciary duties that might otherwise be owed to our partnership, our preferred unitholders and unitholders, including when conflicts of interest arise. Specifically, our Limited Partnership Agreement states that no breach of our Limited Partnership Agreement or a breach of any duty, including fiduciary duties, may be found for any matter that has been approved by a majority of the independent directors of our General Partner. In addition, when resolving conflicts of interest, our Limited Partnership Agreement does not impose any limitations on the discretion of the independent directors or the factors which they may consider in resolving any such conflicts. The independent directors of our General Partner can therefore take into account the interests of third parties, including Brookfield, when resolving conflicts of interest. Additionally, any fiduciary duty that is imposed under any applicable law or agreement is modified, waived or limited to the extent required to permit our General Partner to undertake any affirmative conduct or to make any decisions, so long as such action is reasonably believed to be in, or not inconsistent with, the best interests of our partnership.

        In addition, our Limited Partnership Agreement provides that our General Partner and its affiliates do not have any obligation under our Limited Partnership Agreement, or as a result of any duties stated or implied by law or equity, including fiduciary duties, to present business or investment opportunities to our partnership, the Holding LP, any Holding Entity or any other holding entity established by us. They also allow affiliates of our General Partner to engage in activities that may compete with us or our activities. Additionally, any failure by our General Partner to consent to any merger, consolidation or combination will not result in a breach of our Limited Partnership Agreement or any other provision of law. Our Limited Partnership Agreement prohibits our limited partners from advancing claims that otherwise might raise issues as to compliance with fiduciary duties or applicable law. These modifications to the fiduciary duties are detrimental to our unitholders and preferred unitholders because they restrict the remedies available for actions that might otherwise constitute a breach of fiduciary duty and permit conflicts of interest to be resolved in a manner that is not in the best interests of our partnership or the best interests of our unitholders and preferred unitholders. See Item 7.B "Related Party Transactions—Conflicts of Interest and Fiduciary Duties".

28 Brookfield Infrastructure

Table of Contents

         Our organizational and ownership structure may create significant conflicts of interest that may be resolved in a manner that is not in the best interests of our partnership or the best interests of our unitholders and preferred unitholders.

        Our organizational and ownership structure involves a number of relationships that may give rise to conflicts of interest between our partnership, our unitholders and preferred unitholders, on the one hand, and Brookfield, on the other hand. In certain instances, the interests of Brookfield may differ from the interests of our partnership, our preferred unitholders and our unitholders, including with respect to the types of acquisitions made, the timing and amount of distributions by our partnership, the reinvestment of returns generated by our operations, the use of leverage when making acquisitions and the appointment of outside advisors and service providers, including as a result of the reasons described under Item 7.B "Related Party Transactions".

        In addition, the Service Provider, an affiliate of Brookfield, provides management services to us pursuant to our Master Services Agreement. Pursuant to our Master Services Agreement, on a quarterly basis, we pay a base management fee to the Service Provider equal to 0.3125% (1.25% annually) of the market value of our partnership. For purposes of calculating the base management fee, the market value of our partnership is equal to the aggregate value of all our outstanding units (assuming full conversion of Brookfield's limited partnership interests in Brookfield Infrastructure into units), preferred units and securities of the other Service Recipients that are not held by Brookfield Infrastructure, plus all outstanding third party debt with recourse to a Service Recipient, less all cash held by such entities. Infrastructure Special LP will also receive incentive distributions based on the amount by which quarterly distributions on the Holding LP's units (other than Holding LP Class A Preferred Units) exceed specified target levels as set forth in the Holding LP's limited partnership agreement. For a further explanation of the base management fee and incentive distributions, see Item 6.A "Directors and Senior Management—Management Fee" and Item 7.B "Related Party Transactions—Incentive Distributions". This relationship may give rise to conflicts of interest between us, our unitholders and preferred unitholders, on the one hand, and Brookfield, on the other, as Brookfield's interests may differ from the interests of Brookfield Infrastructure, our unitholders and preferred unitholders.

        Our General Partner, the sole shareholder of which is Brookfield, has sole authority to determine whether we will make distributions and the amount of distributions on our units and timing of these distributions. The arrangements we have with Brookfield may create an incentive for Brookfield to take actions which would have the effect of increasing distributions and fees payable to it, which may be to the detriment of us, our unitholders and preferred unitholders. For example, because the base management fee is calculated based on the market value of our partnership, it may create an incentive for Brookfield to increase or maintain the market value of our partnership over the near-term when other actions may be more favourable to us or our unitholders and preferred unitholders. Similarly, Brookfield may take actions to increase distributions on our units in order to ensure Brookfield is paid incentive distributions in the near-term when other investments or actions may be more favourable to us or our unitholders and preferred unitholders. Also, through Brookfield's ownership of our units and the Redeemable Partnership Units, it has an effective economic interest in our partnership of approximately 29.5% and therefore may be incentivized to increase distributions payable to our unitholders and thereby to Brookfield.

Brookfield Infrastructure 29

Table of Contents

         Our arrangements with Brookfield were negotiated in the context of an affiliated relationship and may contain terms that are less favourable than those which otherwise might have been obtained from unrelated parties.

        The terms of our arrangements with Brookfield were effectively determined by Brookfield in the context of the spin-off. While our General Partner's independent directors are aware of the terms of these arrangements and have approved the arrangements on our behalf, they did not negotiate the terms. These terms, including terms relating to compensation, contractual or fiduciary duties, conflicts of interest and Brookfield's ability to engage in outside activities, including activities that compete with us, our activities and limitations on liability and indemnification, may be less favourable than otherwise might have resulted if the negotiations had involved unrelated parties. Under our Limited Partnership Agreement, persons who acquire our units or preferred units and their transferees will be deemed to have agreed that none of those arrangements constitutes a breach of any duty that may be owed to them under our Limited Partnership Agreement or any duty stated or implied by law or equity.

         Our General Partner may be unable or unwilling to terminate the Master Services Agreement.

        The Master Services Agreement provides that the Service Recipients may terminate the agreement only if: the Service Provider defaults in the performance or observance of any material term, condition or covenant contained in the agreement in a manner that results in material harm to us and the default continues unremedied for a period of 30 days after written notice of the breach is given to the Service Provider; the Service Provider engages in any act of fraud, misappropriation of funds or embezzlement against any Service Recipient that results in material harm to us; the Service Provider is grossly negligent in the performance of its duties under the agreement and such negligence results in material harm to the Service Recipients; or upon the happening of certain events relating to the bankruptcy or insolvency of the Service Provider. Our General Partner cannot terminate the agreement for any other reason, including if the Service Provider or Brookfield experiences a change of control, and there is no fixed term to the agreement. In addition, because our General Partner is an affiliate of Brookfield, it may be unwilling to terminate the Master Services Agreement, even in the case of a default. If the Service Provider's performance does not meet the expectations of investors, and our General Partner is unable or unwilling to terminate the Master Services Agreement, the market price of our units or preferred units could suffer. Furthermore, the termination of the Master Services Agreement would terminate our partnership's rights under the Relationship Agreement and our Licensing Agreements. See Item 7.B "Related Party Transactions—Relationship Agreement" and Item 7.B "Related Party Transactions—Licensing Agreements".

         The liability of the Service Provider is limited under our arrangements with it and we have agreed to indemnify the Service Provider against claims that it may face in connection with such arrangements, which may lead it to assume greater risks when making decisions relating to us than it otherwise would if acting solely for its own account.

        Under the Master Services Agreement, the Service Provider has not assumed any responsibility other than to provide or arrange for the provision of the services described in the Master Services Agreement in good faith and will not be responsible for any action that our General Partner takes in following or declining to follow its advice or recommendations. In addition, under our Limited Partnership Agreement, the liability of our General Partner and its affiliates, including the Service Provider, is limited to the fullest extent permitted by law to conduct involving bad faith, fraud or willful misconduct or, in the case of a criminal matter, action that was known to have been unlawful. The liability of the Service Provider under the Master Services Agreement is similarly limited, except that the Service Provider is also liable for liabilities arising from gross negligence. In addition, our partnership has agreed to indemnify the Service Provider to the fullest extent permitted by law from and against any claims, liabilities, losses, damages, costs or expenses incurred by an indemnified person or threatened in connection with our operations, investments and activities or in respect of or arising from the Master Services Agreement or the services provided by the Service Provider, except to the extent that the claims, liabilities, losses, damages, costs or expenses are determined to have resulted from the conduct in respect of which such persons have liability as described above. These protections may result in the Service Provider tolerating greater risks when making decisions than otherwise would be the case, including when determining whether to use leverage in connection with acquisitions. The indemnification arrangements to which the Service Provider is a party may also give rise to legal claims for indemnification that are adverse to our partnership, our unitholders and preferred unitholders.

Risks Relating to Our Partnership Structure

         Brookfield Infrastructure and our operating entities use leverage and such indebtedness may result in Brookfield Infrastructure or our operating entities being subject to certain covenants which restrict our ability to engage in certain types of activities or to make distributions to equity.

        The Holding LP and many of our Holding Entities and operating entities have entered into credit facilities or have incurred other forms of debt, including for the purposes of acquisitions and investments as well as for general corporate purposes. The total quantum of exposure to debt within Brookfield Infrastructure is significant, and we may become more highly leveraged in the future. Some facilities are fully drawn, while some have amounts of principal which are undrawn.

        Highly leveraged assets are inherently more sensitive to declines in revenues, increases in expenses and interest rates and adverse economic, market and industry developments. A leveraged company's income and net assets also tend to increase or decrease at a greater rate than would otherwise be the case if money had not been borrowed. As a result, the risk of loss associated with a leveraged company, all other things being equal, is generally greater than for companies with comparatively less debt. In addition, the use of indebtedness in connection with an acquisition may give rise to negative tax consequences to certain investors. Leverage may also result in a requirement for short-term liquidity, which may force the sale of assets at times of low demand and/or prices for such assets. This may mean that we are unable to realize fair value for the assets in a sale.

        Our credit facilities also contain covenants applicable to the relevant borrower and events of default. Covenants can relate to matters including limitations on financial indebtedness, dividends, investments, or minimum amounts for interest coverage, Adjusted EBITDA, cash flow or net worth. If an event of default occurs, or minimum covenant requirements are not satisfied, this can result in a requirement to immediately repay any drawn amounts or the imposition of other restrictions including a prohibition on the payment of distributions to equity.

        Our credit facilities or other debt or debt-like instruments may or may not be rated. Should such debt or debt-like instruments be rated, a credit downgrade may have an adverse impact on the cost of such debt.

         Our partnership is a holding entity and currently we rely on the Holding LP and, indirectly, the Holding Entities and our operating entities to provide us with the funds necessary to pay distributions and meet our financial obligations.

        Our partnership is a holding entity and its sole material asset is its managing general partnership interest and preferred limited partnership interest in the Holding LP, which owns all of the common shares of the Holding Entities, through which we hold all of our interests in the operating entities. Our partnership has no independent means of generating revenue. As a result, we depend on distributions and other payments from the Holding LP and, indirectly, the Holding Entities and our operating entities to provide us with the funds necessary to pay distributions on our units and preferred units and to meet our financial obligations. The Holding LP, the Holding Entities and our operating entities are legally distinct from us and some of them are or may become restricted in their ability to pay dividends and distributions or otherwise make funds available to us pursuant to local law, regulatory requirements and their contractual agreements, including agreements governing their financing arrangements, such as the Holding LP's credit facilities and other indebtedness incurred by the Holding Entities and operating entities. Any other entities through which we may conduct operations in the future will also be legally distinct from us and may be similarly restricted in their ability to pay dividends and distributions or otherwise make funds available to us under certain conditions. The Holding LP, the Holding Entities and our operating entities will generally be required to service their debt obligations before making distributions to us or their parent entities, as applicable, thereby reducing the amount of our cash flow available to pay distributions, fund working capital and satisfy other needs.

        Our partnership anticipates that the only distributions that it will receive in respect of our partnership's managing general partnership interest in the Holding LP will consist of amounts that are intended to assist our partnership in making distributions to our unitholders in accordance with our partnership's distribution policy and to allow our partnership to pay expenses as they become due. Distributions received in respect of our partnership's preferred limited partnership interest in the Holding LP will consist of amounts that are intended to assist our partnership in making distributions to our preferred unitholders in accordance with the terms of our preferred units. The declaration and payment of cash distributions by our partnership is at the discretion of our General Partner. Our partnership is not required to make such distributions and neither our partnership nor our General Partner can assure you that our partnership will make such distributions as intended.

        While we plan to review our partnership's distributions to our unitholders periodically, there is no guarantee that we will be able to increase, or even maintain the level of distributions that are paid. Historically, as a result of this review, we decided to increase distributions in each of the last five years. However, such historical increases in distribution payments may not be reflective of any future increases in distribution payments which will be subject to review by the board of directors of our General Partner taking into account prevailing circumstances at the relevant time. Although we intend to make distributions on our units in accordance with our distribution policy, our partnership is not required to pay distributions on our units and neither our partnership nor our General Partner can assure you that our partnership will be able to increase or even maintain the level of distributions on our units that are made in the future.

         Future sales or issuances of our units or preferred units in the public markets, or the perception of such sales or issuances, could depress the trading price of our units and/or preferred units.

        The sale or issuance of a substantial number of our units, preferred units or other equity related securities of our partnership in the public markets, or the perception that such sales or issuances could occur, could depress the market price of our units or preferred units and impair our ability to raise capital through the sale of additional units or preferred units. For example, in December 2016, we issued 15,625,000 units in a public offering in the United States and Canada, together with 8,139,000 additional Redeemable Partnership Units to Brookfield in a concurrent private placement, and in August 2016, we raised C$250 million of gross proceeds through the issuance of Series 5 Preferred Units in Canada. We cannot predict the effect that future sales or issuances of our units, preferred units or other equity-related securities would have on the market price of our units or preferred units.

         Our partnership is not, and does not intend to become, regulated as an investment company under the Investment Company Act (and similar legislation in other jurisdictions) and if our partnership was deemed an "investment company" under the Investment Company Act, applicable restrictions could make it impractical for us to operate as contemplated.

        The Investment Company Act (and similar legislation in other jurisdictions) provide certain protections to investors and impose certain restrictions on companies that are required to be regulated as investment companies. Among other things, such rules limit or prohibit transactions with affiliates, impose limitations on the issuance of debt and equity securities and impose certain governance requirements. Our partnership has not been and does not intend to become regulated as an investment company and our partnership intends to conduct its activities so it will not be deemed to be an investment company under the Investment Company Act (and similar legislation in other jurisdictions). In order to ensure that we are not deemed to be an investment company, we may be required to materially restrict or limit the scope of our operations or plans. We will be limited in the types of acquisitions that we may make, and we may need to modify our organizational structure or dispose of assets of which we would not otherwise dispose. Moreover, if anything were to happen which causes our partnership to be deemed an investment company under the Investment Company Act, it would be impractical for us to operate as contemplated. Agreements and arrangements between and among us and Brookfield would be impaired, the type and amount of acquisitions that we would be able to make as a principal would be limited and our business, financial condition and results of operations would be materially adversely affected. Accordingly, we would be required to take extraordinary steps to address the situation, such as the amendment or termination of the Master Services Agreement, the restructuring of our partnership and the Holding Entities, the amendment of our Limited Partnership Agreement or the termination of our partnership, any of which could materially adversely affect the value of our units and preferred units. In addition, if our partnership were deemed to be an investment company under the Investment Company Act, it would be taxable as a corporation for U.S. federal income tax purposes, and such treatment could materially adversely affect the value of our units and preferred units.

         Our partnership is an "SEC foreign issuer" under Canadian securities regulations and is exempt from certain requirements of Canadian securities laws and a "foreign private issuer" under U.S. securities laws and as a result is subject to disclosure obligations different from requirements applicable to U.S. domestic registrants listed on the New York Stock Exchange ("NYSE").

        Although our partnership is a reporting issuer in Canada, it is an "SEC foreign issuer" and is exempt from certain Canadian securities laws relating to disclosure obligations and proxy solicitation, subject to certain conditions. Therefore, there may be less publicly available information in Canada about our partnership than would be available if we were a typical Canadian reporting issuer.

        Although our partnership is subject to the periodic reporting requirement of the U.S. Securities Exchange Act of 1934 , as amended, and the rules and regulations promulgated thereunder ("Exchange Act"), the periodic disclosure required of foreign private issuers under the Exchange Act is different from periodic disclosure required of U.S. domestic registrants. Therefore, there may be less publicly available information about our partnership than is regularly published by or about other public limited partnerships in the U.S. Our partnership is exempt from certain other sections of the Exchange Act to which U.S. domestic issuers are subject, including the requirement to provide our unitholders with information statements or proxy statements that comply with the Exchange Act. In addition, insiders and large unitholders of our partnership are not obligated to file reports under Section 16 of the Exchange Act, and certain corporate governance rules imposed by the NYSE are inapplicable to our partnership.

         We may be subject to the risks commonly associated with a separation of economic interest from control or the incurrence of debt at multiple levels within an organizational structure.

        Our ownership and organizational structure is similar to structures whereby one company controls another company which in turn holds controlling interests in other companies; thereby, the company at the top of the chain may control the company at the bottom of the chain even if its effective equity position in the bottom company is less than a controlling interest. Brookfield controls the sole shareholder of our General Partner and, as a result of such ownership of our General Partner, Brookfield is able to control the appointment and removal of our General Partner's directors and, accordingly, exercises substantial influence over us. In turn, we often have a majority controlling interest or a significant influence in our investments. Even though Brookfield currently has an effective economic interest in our partnership of approximately 29.5% as a result of ownership of our units and the Redeemable Partnership Units, over time Brookfield may reduce this economic interest while still maintaining its controlling interest, and, therefore, Brookfield may use its control rights in a manner that conflicts with the economic interests of our other unitholders and preferred unitholders. For example, despite the fact that we have a conflicts protocol in place, which addresses the requirement for independent approval and other requirements for transactions in which there is greater potential for a conflict of interest to arise, including transactions with affiliates of Brookfield, because Brookfield will be able to exert substantial influence over us, and, in turn, over our investments, there is a greater risk of transfer of assets of our investments at non-arm's length values to Brookfield and its affiliates. In addition, debt incurred at multiple levels within the chain of control could exacerbate the separation of economic interest from controlling interest at such levels, thereby creating an incentive to leverage us and our investments. Any such increase in debt would also make us more sensitive to declines in revenues, increases in expenses and interest rates, and adverse market conditions. The servicing of any such debt would also reduce the amount of funds available to pay distributions to us and ultimately to our unitholders and preferred unitholders.

         Our failure to maintain effective internal controls could have a material adverse effect on our business in the future and the price of our units and preferred units.

        Any failure to maintain adequate internal controls over financial reporting or to implement required, new or improved controls, or difficulties encountered in their implementation, could cause us to report material weaknesses or other deficiencies in our internal controls over financial reporting and could result in errors or misstatements in our consolidated financial statements that could be material. If we or our independent registered public accounting firm were to conclude that our internal controls over financial reporting were not effective, investors could lose confidence in our reported financial information and the price of our units and preferred units could decline. Our failure to achieve and maintain effective internal controls could have a material adverse effect on our business in the future, our access to the capital markets and investors' perception of us. In addition, material weaknesses in our internal controls could require significant expense and management time to remediate.

Risks Relating to Our Units and Preferred Units

         Our unitholders and preferred unitholders do not have a right to vote on partnership matters or to take part in the management of our partnership.

        Under our Limited Partnership Agreement, our unitholders and preferred unitholders are not entitled to vote on matters relating to our partnership, such as acquisitions, dispositions or financing, or to participate in the management or control of our partnership. In particular, our unitholders and preferred unitholders do not have the right to remove our General Partner, to cause our General Partner to withdraw from our partnership, to cause a new general partner to be admitted to our partnership, to appoint new directors to our General Partner's board of directors, to remove existing directors from our General Partner's board of directors or to prevent a change of control of our General Partner. In addition, except for certain fundamental matters and as prescribed by applicable laws, our unitholders' and preferred unitholders consent rights apply only with respect to certain amendments to our Limited Partnership Agreement. As a result, unlike holders of common stock of a corporation, our unitholders are not able to influence the direction of our partnership, including its policies and procedures, or to cause a change in its management, even if they are unsatisfied with the performance of our partnership. Consequently, our unitholders may be deprived of an opportunity to receive a premium for their units in the future through a sale of our partnership and the trading price of our units may be adversely affected by the absence or a reduction of a takeover premium in the trading price. Unitholders and preferred unitholders only have a right to vote under limited circumstances as described in Item 10.B "Memorandum and Articles of Association—Description of Our Units, Preferred Units and Our Limited Partnership Agreement."

         The market price of our units and preferred units may be volatile.

        The market price of our units and preferred units may be highly volatile and could be subject to wide fluctuations. Some of the factors that could negatively affect the price of our units and preferred units include: general market and economic conditions, including disruptions, downgrades, credit events and perceived problems in the credit markets; actual or anticipated variations in our quarterly operating results or distributions on our units; actual or anticipated variations or trends in market interest rates; changes in our investments or asset composition; write-downs or perceived credit or liquidity issues affecting our assets; market perception of our partnership, our business and our assets; our level of indebtedness and/or adverse market reaction to any indebtedness we incur in the future; our ability to raise capital on favourable terms or at all; loss of any major funding source; the termination of our Master Services Agreement or additions or departures of our or Brookfield's key personnel; changes in market valuations of similar infrastructure companies; speculation in the press or investment community regarding us or Brookfield; and changes in U.S. tax laws that make it impractical or impossible for our partnership to continue to be taxable as a partnership for U.S. federal income tax purposes. Securities markets in general have experienced extreme volatility that has often been unrelated to the operating performance of particular companies or partnerships. Any broad market fluctuations may adversely affect the trading price of our units and preferred units.

         We may need additional funds in the future and we may issue additional units or preferred units in lieu of incurring indebtedness which may dilute existing holders of our units or we may issue securities that have rights and privileges that are more favourable than the rights and privileges accorded to our unitholders and preferred unitholders.

        Under our Limited Partnership Agreement subject to the terms of any preferred units then outstanding, we may issue additional partnership securities, including units, preferred units and options, rights, warrants and appreciation rights relating to partnership securities for any purpose and for such consideration and on such terms and conditions as our General Partner may determine. Subject to the terms of any preferred units outstanding, our General Partner's board of directors will be able to determine the class, designations, preferences, rights, powers and duties of any additional partnership securities, including any rights to share in our profits, losses and distributions, any rights to receive partnership assets upon our dissolution or liquidation and any redemption, conversion and exchange rights. Subject to the terms of any preferred units outstanding, our General Partner may use such authority to issue additional units or preferred units, which could dilute holders of our units, or to issue securities with rights and privileges that are more favourable than those of our units or preferred units. Subject to the terms of any preferred units then outstanding, holders of units and preferred units will not have any pre-emptive right or any right to consent to or otherwise approve the issuance of any such securities or the terms on which any such securities may be issued.

         Non-U.S. unitholders will be subject to foreign currency risk associated with Brookfield Infrastructure's distributions.

        A significant number of our unitholders will reside in countries where the U.S. dollar is not the functional currency. Our distributions are denominated in U.S. dollars but are settled in the local currency of the unitholder receiving the distribution. For each non-U.S. unitholder, the value received in the local currency from the distribution will be determined based on the exchange rate between the U.S. dollar and the applicable local currency at the time of payment. As such, if the U.S. dollar depreciates significantly against the local currency of the non-U.S. unitholder, the value received by such unitholder in its local currency will be adversely affected.

         U.S. investors in our units and preferred units may find it difficult or impossible to enforce service of process and enforcement of judgments against us and directors and officers of our General Partner and the Service Provider.

        We were established under the laws of Bermuda, and most of our subsidiaries are organized in jurisdictions outside of the United States. In addition, our directors and senior management identified in this annual report on Form 20-F are located outside of the United States. Certain of the directors and officers of our General Partner and the Service Provider reside outside of the United States. A substantial portion of our assets are, and the assets of the directors and officers of our General Partner and the Service Provider identified in this annual report on Form 20-F may be, located outside of the United States. It may not be possible for investors to effect service of process within the United States upon the directors and officers of our General Partner and the Service Provider. It may also not be possible to enforce against us or the directors and officers of our General Partner and the Service Provider judgments obtained in U.S. courts predicated upon the civil liability provisions of applicable securities law in the United States.

         Canadian investors in our units and preferred units may find it difficult or impossible to enforce service of process and enforcement of judgments against us and the directors and officers of our General Partner and the Service Provider.

        We were established under the laws of Bermuda, and most of our subsidiaries are organized in jurisdictions outside of Canada. Certain of the directors and officers of our General Partner and the Service Provider reside outside of Canada. A substantial portion of our assets are, and the assets of the directors and officers of our General Partner and the Service Provider and the experts identified in this annual report on Form 20-F may be, located outside of Canada. It may not be possible for investors to effect service of process within Canada upon the directors and officers of our General Partner and the Service Provider. It may also not be possible to enforce against us, the experts identified in this annual report on Form 20-F, or the directors and officers of our General Partner and the Service Provider judgments obtained in Canadian courts predicated upon the civil liability provisions of applicable securities laws in Canada.

         We may not be able to continue paying comparable or growing cash distributions to our unitholders in the future.

        The amount of cash we can distribute to our unitholders depends upon the amount of cash we receive from the Holding LP and, indirectly, the Holding Entities and the operating entities. The amount of cash the Holding LP, the Holding Entities and the operating entities generate will fluctuate from quarter to quarter and will depend upon, among other things: the weather in the jurisdictions in which they operate; the level of their operating costs; and prevailing economic conditions. In addition, the actual amount of cash we will have available for distribution will also depend on other factors, such as: the level of costs related to litigation and regulatory compliance matters; the cost of acquisitions, if any; our debt service requirements; fluctuations in our working capital needs; our ability to borrow under our credit facilities; our ability to access capital markets; restrictions on distributions contained in our debt agreements; and the amount, if any, of cash reserves established by our General Partner in its discretion for the proper conduct of our business. As a result of all these factors, we cannot guarantee that we will have sufficient available cash to pay a specific level of cash distributions to our unitholders. Furthermore, unitholders should be aware that the amount of cash we have available for distribution depends primarily upon the cash flow of the Holding LP, the Holding Entities and the operating entities, and is not solely a function of profitability, which is affected by non-cash items. As a result, we may declare and/or pay cash distributions on our units during periods when we record net losses.

Risks Related to Taxation

General

         Changes in tax law and practice may have a material adverse effect on the operations of our partnership, the Holding Entities, and the operating entities and, as a consequence, the value of our assets and the net amount of distributions payable to our unitholders.

        Our structure, including the structure of the Holding Entities and the operating entities, is based on prevailing taxation law and practice in the local jurisdictions in which we operate. Any change in tax legislation (including in relation to taxation rates) and practice in these jurisdictions could adversely affect these entities, as well as the net amount of distributions payable to our unitholders. Taxes and other constraints that would apply to our operating entities in such jurisdictions may not apply to local institutions or other parties, and such parties may therefore have a significantly lower effective cost of capital and a corresponding competitive advantage in pursuing such acquisitions.

Brookfield Infrastructure 37

Table of Contents

         Our partnership's ability to make distributions depends on it receiving sufficient cash distributions from its underlying operations, and we cannot assure our unitholders that our partnership will be able to make cash distributions to them in amounts that are sufficient to fund their tax liabilities.

        Our Holding Entities and operating entities may be subject to local taxes in each of the relevant territories and jurisdictions in which they operate, including taxes on income, profits or gains and withholding taxes. As a result, our partnership's cash available for distribution is indirectly reduced by such taxes, and the post-tax return to our unitholders is similarly reduced by such taxes. We intend for future acquisitions to be assessed on a case-by-case basis and, where possible and commercially viable, structured so as to minimize any adverse tax consequences to our unitholders as a result of making such acquisitions.

        In general, a unitholder that is subject to income tax in Canada or the United States must include in income its allocable share of our partnership's items of income, gain, loss and deduction (including, so long as it is treated as a partnership for tax purposes, our partnership's allocable share of those items of the Holding LP) for each of our partnership's fiscal years ending with or within such unitholder's tax year. See Item 10.E "Taxation—Certain Material Canadian Federal Income Tax Considerations" and "Taxation—Certain Material U.S. Federal Income Tax Considerations". However, the cash distributed to a unitholder may not be sufficient to pay the full amount of such unitholder's tax liability in respect of its investment in our partnership, because each unitholder's tax liability depends on such unitholder's particular tax situation and the tax treatment of the underlying activities or assets of our partnership. If our partnership is unable to distribute cash in amounts that are sufficient to fund our unitholders' tax liabilities, each of our unitholders will still be required to pay income taxes on its share of our partnership's taxable income.

         As a result of holding our units, our unitholders may be subject to U.S. federal, state, local or non-U.S. taxes and return filing obligations in jurisdictions in which they are not resident for tax purposes or otherwise not subject to tax.

        Our unitholders may be subject to U.S. federal, state, local and non-U.S. taxes, including unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which our partnership entities do business or own property now or in the future, even if our unitholders do not reside in any of those jurisdictions. Our unitholders may be required to file income tax returns and pay income taxes in some or all of these jurisdictions. Further, our unitholders may be subject to penalties for failure to comply with these requirements. Although our partnership will attempt, to the extent reasonably practicable, to structure our partnership operations and investments so as to minimize income tax filing obligations by our unitholders in such jurisdictions, there may be circumstances in which our partnership is unable to do so. It is the responsibility of each unitholder to file all U.S. federal, state, local, and non-U.S. tax returns that may be required of such unitholder.

Our unitholders may be exposed to transfer pricing risks.

        To the extent that our partnership, the Holding LP, the Holding Entities or the operating entities enter into transactions or arrangements with parties with whom they do not deal at arm's length, including Brookfield, the relevant tax authorities may seek to adjust the quantum or nature of the amounts included or deducted from taxable income by such entities if they consider that the terms and conditions of such transactions or arrangements differ from those that would have been made between persons dealing at arm's length. This could result in more tax (and penalties and interest) being paid by such entities, and therefore the return to investors could be reduced. For Canadian tax purposes, a transfer pricing adjustment may in certain circumstances result in additional income being allocated to a unitholder with no corresponding cash distribution or in a dividend being deemed to be paid by a Canadian-resident to a non-arm's length non-resident, which is subject to Canadian withholding tax.

        Our General Partner believes that the base management fee and any other amount that is paid to the Service Provider will be commensurate with the value of the services being provided by the Service Provider and comparable to the fees or other amounts that would be agreed to in an arm's length arrangement. However, no assurance can be given in this regard.

        If the relevant tax authority were to assert that an adjustment should be made under the transfer pricing rules to an amount that is relevant to the computation of the income of the Holding LP or our partnership, such assertion could result in adjustments to amounts of income (or loss) allocated to our unitholders by our partnership for tax purposes. In addition, we might also be liable for transfer pricing penalties in respect of transfer pricing adjustments unless reasonable efforts were made to determine, and use, arm's length transfer prices. Generally, reasonable efforts in this regard are only considered to be made if contemporaneous documentation has been prepared in respect of such transactions or arrangements that support the transfer pricing methodology.

        For Canadian tax purposes, the general tax risks described above are equally relevant to preferred unitholders in respect of their preferred units.

         The U.S. Internal Revenue Service ("IRS") or Canada Revenue Agency ("CRA") may not agree with certain assumptions and conventions that our partnership uses in order to comply with applicable U.S. and Canadian federal income tax laws or that our partnership uses to report income, gain, loss, deduction, and credit to our unitholders.

        Our partnership will apply certain assumptions and conventions in order to comply with applicable tax laws and to report income, gain, deduction, loss, and credit to a unitholder in a manner that reflects such unitholder's beneficial ownership of partnership items, taking into account variation in ownership interests during each taxable year because of trading activity. However, these assumptions and conventions may not be in compliance with all aspects of the applicable tax requirements. A successful IRS or CRA challenge to such assumptions or conventions could adversely affect the amount of tax benefits available to our unitholders and could require that items of income, gain, deduction, loss, or credit, including interest deductions, be adjusted, reallocated or disallowed in a manner that adversely affects our unitholders. See Item 10.E "Taxation—Certain Material Canadian Federal Income Tax Considerations" and "Taxation—Certain Material U.S. Federal Income Tax Considerations".

United States

         If our partnership or the Holding LP were to be treated as a corporation for U.S. federal income tax purposes, the value of our units might be adversely affected.

        The value of our units to unitholders will depend in part on the treatment of our partnership and the Holding LP as partnerships for U.S. federal income tax purposes. However, in order for our partnership to be treated as a partnership for U.S. federal income tax purposes, under present law, 90% or more of our partnership's gross income for every taxable year must consist of qualifying income, as defined in Section 7704 of the U.S. Internal Revenue Code of 1986, as amended ("U.S. Internal Revenue Code"), and our partnership must not be required to register, if it were a U.S. corporation, as an investment company under the Investment Company Act and related rules. Although our General Partner intends to manage our partnership's affairs so that our partnership will not need to be registered as an investment company if it were a U.S. corporation and so that it will meet the 90% test described above in each taxable year, our partnership may not meet these requirements, or current law may change so as to cause, in either event, our partnership to be treated as a corporation for U.S. federal income tax purposes. If our partnership (or the Holding LP) were treated as a corporation for U.S. federal income tax purposes, adverse U.S. federal income tax consequences could result for our unitholders and our partnership (or the Holding LP, as applicable), as described in greater detail in Item 10.E "Taxation—Certain Material U.S. Federal Income Tax Considerations—Partnership Status of Our Partnership and the Holding LP".

         We may be subject to U.S. backup withholding tax or other U.S. withholding taxes if any unitholder fails to comply with U.S. tax reporting rules or if the IRS or other applicable state or local taxing authority does not accept our withholding methodology, and such excess withholding tax cost will be an expense borne by our partnership and, therefore, by all of our unitholders on a pro rata basis.

        We may become subject to U.S. "backup" withholding tax or other U.S. withholding taxes with respect to any unitholder who fails to timely provide our partnership (or the applicable clearing agent or other intermediary) with an IRS Form W-9 or IRS Form W-8, as the case may be, or if the withholding methodology we use is not accepted by the IRS or other applicable state or local taxing authority. See Item 10.E "Taxation—Certain Material U.S. Federal Income Tax Considerations—Administrative Matters—Withholding and Backup Withholding". To the extent that any unitholder fails to timely provide the applicable form (or such form is not properly completed), or should the IRS or other applicable state or local taxing authority not accept our withholding methodology, our partnership might treat such U.S. backup withholding taxes or other U.S. withholding taxes as an expense, which would be borne indirectly by all of our unitholders on a pro rata basis. As a result, our unitholders that fully comply with their U.S. tax reporting obligations may bear a share of such burden created by other unitholders that do not comply with the U.S. tax reporting rules.

         Tax-exempt organizations may face certain adverse U.S. tax consequences from owning our units.

        Our General Partner intends to use commercially reasonable efforts to structure the activities of our partnership and the Holding LP, to avoid generating income connected with the conduct of a trade or business (which income generally would constitute "unrelated business taxable income" ("UBTI") to the extent allocated to a tax-exempt organization). However, neither our partnership nor the Holding LP is prohibited from incurring indebtedness, and no assurance can be provided that neither our partnership nor the Holding LP will generate UBTI attributable to debt-financed property in the future. In particular, UBTI includes income attributable to debt-financed property, and neither our partnership nor the Holding LP is prohibited from financing the acquisition of property with debt. The potential for income to be characterized as UBTI could make our units an unsuitable investment for a tax-exempt organization. Each tax-exempt organization should consult its own tax adviser to determine the U.S. federal income tax consequences of an investment in our units.

         If our partnership were engaged in a U.S. trade or business, non-U.S. persons would face certain adverse U.S. tax consequences from owning our units.

        Our General Partner intends to use commercially reasonable efforts to structure the activities of our partnership and the Holding LP to avoid generating income treated as effectively connected with a U.S. trade or business, including effectively connected income attributable to the sale of a "United States real property interest", as defined in the U.S. Internal Revenue Code. If our partnership were deemed to be engaged in a U.S. trade or business, or to realize gain from the sale or other disposition of a U.S. real property interest, Non-U.S. Holders (as defined in Item 10.E "Taxation—Certain Material U.S. Federal Income Tax Considerations") generally would be required to file U.S. federal income tax returns and could be subject to U.S. federal withholding tax at the highest marginal U.S. federal income tax rates applicable to ordinary income. See Item 10.E "Taxation—Certain Material U.S. Federal Income Tax Considerations—Consequences to Non-U.S. Holders".

         To meet U.S. federal income tax and other objectives, our partnership and the Holding LP may invest through U.S. and non-U.S. Holding Entities that are treated as corporations for U.S. federal income tax purposes, and such Holding Entities may be subject to corporate income tax.

        To meet U.S. federal income tax and other objectives, our partnership and the Holding LP may invest through U.S. and non-U.S. Holding Entities that are treated as corporations for U.S. federal income tax purposes, and such Holding Entities may be subject to corporate income tax. Consequently, items of income, gain, loss, deduction, or credit realized in the first instance by the operating entities will not flow, for U.S. federal income tax purposes, directly to the Holding LP, our partnership, or our unitholders, and any such income or gain may be subject to a corporate income tax, in the United States or other jurisdictions, at the level of the Holding Entity. Any such additional taxes may adversely affect our partnership's ability to maximize its cash flow.

         Our unitholders taxable in the United States may be viewed as holding an indirect interest in an entity classified as a "passive foreign investment company" or "controlled foreign corporation" for U.S. federal income tax purposes.

        U.S. Holders may face adverse U.S. tax consequences arising from the ownership of an indirect interest in a "passive foreign investment company" ("PFIC") or "controlled foreign corporation" ("CFC"). These investments may produce taxable income prior to the receipt of cash relating to such income, and U.S. Holders will be required to take such income into account in determining their gross income subject to tax. In addition, all or a portion of any gain realized upon the sale of a CFC may be taxable at ordinary income rates. Further, with respect to gain realized upon the sale of and excess distributions from a PFIC for which an election for current inclusions is not made, such income would be taxable at ordinary income rates and subject to an additional tax equivalent to an interest charge on the deferral of income inclusions from the PFIC. See Item 10.E "Taxation—Certain Material U.S. Federal Income Tax Considerations—Consequences to U.S. Holders—Passive Foreign Investment Companies" and "Taxation—Certain Material U.S. Federal Income Tax Considerations—Consequences to U.S. Holders—Controlled Foreign Corporations". Each U.S. Holder should consult its own tax adviser regarding the implications of the PFIC and CFC rules for an investment in our units.

         Tax gain or loss from the disposition of our units could be more or less than expected.

        If a sale of our units by a unitholder is taxable in the United States, the unitholder will recognize gain or loss for U.S. federal income tax purposes equal to the difference between the amount realized and the unitholder's adjusted tax basis in such units. Prior distributions to a unitholder in excess of the total net taxable income allocated to such unitholder will have decreased such unitholder's tax basis in our units. Therefore, such excess distributions will increase a unitholder's taxable gain or decrease such unitholder's taxable loss when our units are sold, and may result in a taxable gain even if the sale price is less than the original cost. A portion of the amount realized, whether or not representing gain, could be ordinary income to such unitholder.

         Our partnership structure involves complex provisions of U.S. federal income tax law for which no clear precedent or authority may be available. The tax characterization of our partnership structure is also subject to potential legislative, judicial, or administrative change and differing interpretations, possibly on a retroactive basis.

        The U.S. federal income tax treatment of our unitholders depends in some instances on determinations of fact and interpretations of complex provisions of U.S. federal income tax law for which no clear precedent or authority may be available. Unitholders should be aware that the U.S. federal income tax rules, particularly those applicable to partnerships, are constantly under review by the Congressional tax-writing committees and other persons involved in the legislative process, the IRS, the Treasury Department and the courts, frequently resulting in changes which could adversely affect the value of our units or cause our partnership to change the way it conducts its activities. For example, changes to the U.S. federal tax laws and interpretations thereof could make it more difficult or impossible for our partnership to be treated as a partnership that is not taxable as a corporation for U.S. federal income tax purposes, change the character or treatment of portions of our partnership's income, reduce the net amount of distributions available to our unitholders, or otherwise affect the tax considerations of owning our units. In addition, our partnership's organizational documents and agreements permit our General Partner to modify our Limited Partnership Agreement, without the consent of our unitholders, to address such changes. These modifications could have a material adverse impact on our unitholders. See Item 10.E "—Taxation—Certain Material U.S. Federal Income Tax Considerations—Administrative Matters—New Legislation or Administrative or Judicial Action".

         Our partnership's delivery of required tax information for a taxable year may be subject to delay, which could require a unitholder who is a U.S. taxpayer to request an extension of the due date for such unitholder's income tax return.

        Our partnership has agreed to use commercially reasonable efforts to provide U.S. tax information (including IRS Schedule K-1 information needed to determine a unitholder's allocable share of our partnership's income, gain, losses, and deductions) no later than 90 days after the close of each calendar year. However, providing this U.S. tax information to our unitholders will be subject to delay in the event of, among other reasons, the late receipt of any necessary tax information from lower-tier entities. It is therefore possible that, in any taxable year, a unitholder will need to apply for an extension of time to file such unitholder's tax returns. In addition, unitholders that do not ordinarily have U.S. federal tax filing requirements will not receive a Schedule K-1 and related information unless such unitholders request it within 60 days after the close of each calendar year. See Item 10.E "Certain Material U.S. Federal Income Tax Considerations—Administrative Matters—Information Returns and Audit Procedures".

         The sale or exchange of 50% or more of our units will result in the constructive termination of our partnership for U.S. federal income tax purposes.

        Our partnership will be considered to have been terminated for U.S. federal income tax purposes if there is a sale or exchange of 50% or more of our units within a 12-month period. A constructive termination of our partnership would, among other things; result in the closing of its taxable year for U.S. federal income tax purposes for all of our unitholders and could result in the possible acceleration of income to certain of our unitholders and certain other consequences that could adversely affect the value of our units. However, our General Partner does not expect a constructive termination, should it occur, to have a material impact on the computation of the future taxable income generated by our partnership for U.S. federal income tax purposes. See Item 10.E "Taxation—Certain Material U.S. Federal Income Tax Considerations—Administrative Matters—Constructive Termination".

         If the IRS makes an audit adjustment to our income tax returns for taxable years beginning after December 31, 2017, it may assess and collect any taxes (including penalties and interest) resulting from such audit adjustment directly from us, in which case cash available for distribution to our unitholders might be substantially reduced.

        Under the Bipartisan Budget Act of 2015 , for taxable years beginning after December 31, 2017, if the IRS makes an audit adjustment to our income tax returns, it may assess and collect any taxes (including penalties and interest) resulting from such audit adjustment directly from our partnership instead of unitholders (as under prior law). We may be permitted to elect to have our General Partner and our unitholders take such audit adjustment into account in accordance with their interests in us during the taxable year under audit. However, there can be no assurance that we will choose to make such election or that it will be available in all circumstances. If we do not make the election, and we pay taxes, penalties, or interest as a result of an audit adjustment, then cash available for distribution to our unitholders might be substantially reduced. As a result, our current unitholders might bear some or all of the cost of the tax liability resulting from such audit adjustment, even if our current unitholders did not own our units during the taxable year under audit. The foregoing considerations also apply with respect to our partnership's interest in the Holding LP. These rules do not apply to our partnership or the Holding LP for taxable years beginning on or before December 31, 2017.

         Under the Foreign Account Tax Compliance ("FATCA") provisions of the Hiring Incentives to Restore Employment Act of 2010, certain payments made or received by our partnership may be subject to a 30% federal withholding tax, unless certain requirements are met.

        Under FATCA, a 30% withholding tax may apply to certain payments of U.S.-source income made to our partnership, the Holding LP, the Holding Entities, or the operating entities, or by our partnership to a unitholder, unless certain requirements are met, as described in greater detail in Item 10.E "Taxation—Certain Material U.S. Federal Income Tax Considerations—Administrative Matters—Foreign Account Tax Compliance". The 30% withholding tax may also apply to certain payments made on or after January 1, 2019 that are attributable to U.S.-source income or that constitute gross proceeds from the disposition of property that could produce U.S.-source dividends or interest. To ensure compliance with FATCA, information regarding certain unitholders' ownership of our units may be reported to the IRS or to a non-U.S. governmental authority. Unitholders should consult their own tax advisers regarding the consequences under FATCA of an investment in our units.

         If the subsidiaries that are corporations ("Non-Resident Subsidiaries") and that are not resident or deemed to be resident in Canada for purposes of the Income Tax Act (Canada) (together with the regulations thereunder, "Tax Act") and that are "controlled foreign affiliates" (as defined in the Tax Act and referred to herein as "CFAs") in which the Holding LP directly invests earned income that is "foreign accrual property income" (as defined in the Tax Act and referred to herein as "FAPI"), our unitholders may be required to include amounts allocated from our partnership in computing their income for Canadian federal income tax purposes even though there may be no corresponding cash distribution.

        Certain of the Non-Resident Subsidiaries in which the Holding LP directly invests are expected to be CFAs of the Holding LP. If any CFA of the Holding LP or any direct or indirect subsidiary thereof that is itself a CFA of the Holding LP (an "Indirect CFA") earns income that is characterized as FAPI in a particular taxation year of the CFA or Indirect CFA, the FAPI allocable to the Holding LP must be included in computing the income of the Holding LP for Canadian federal income tax purposes for the fiscal period of the Holding LP in which the taxation year of that CFA or Indirect CFA ends, whether or not the Holding LP actually receives a distribution of that FAPI. Our partnership will include its share of such FAPI of the Holding LP in computing its income for Canadian federal income tax purposes and our unitholders will be required to include their proportionate share of such FAPI allocated from our partnership in computing their income for Canadian federal income tax purposes. As a result, our unitholders may be required to include amounts in their income for Canadian federal income tax purposes even though they have not and may not receive an actual cash distribution of such amounts. The Tax Act contains anti-avoidance rules to address certain foreign tax credit generator transactions (the "Foreign Tax Credit Generator Rules"). Under the Foreign Tax Credit Generator Rules, the "foreign accrual tax" (as defined in the Tax Act) applicable to a particular amount of FAPI included in the Holding LP's income in respect of a particular "foreign affiliate" (as defined in the Tax Act) of the Holding LP may be limited in certain specified circumstances. See Item 10.E "Taxation—Certain Material Canadian Federal Income Tax Considerations".

         Unitholders may be required to include imputed amounts in their income for Canadian federal income tax purposes in accordance with section 94.1 of the Tax Act.

        Section 94.1 of the Tax Act contains rules relating to interests in entities that are not resident or deemed to be resident in Canada for purposes of the Tax Act or not situated in Canada, other than a CFA of the taxpayer (the "Non-Resident Entities"), that could in certain circumstances cause income to be imputed to unitholders for Canadian federal income tax purposes, either directly or by way of allocation of such income imputed to our partnership or to the Holding LP. See Item 10.E "Taxation—Certain Material Canadian Federal Income Tax Considerations".

         Unitholders' foreign tax credits for Canadian federal income tax purposes will be limited if the Foreign Tax Credit Generator Rules apply in respect of the foreign "business-income tax" or "non-business-income tax" (each as defined in the Tax Act) paid by our partnership or the Holding LP to a foreign country.

        Under the Foreign Tax Credit Generator Rules, the foreign "business-income tax" or "non-business-income tax" for Canadian federal income tax purposes for any taxation year may be limited in certain circumstances. If the Foreign Tax Credit Generator Rules apply, the allocation to a unitholder of foreign "business-income tax" or "non-business-income tax" paid by our partnership or the Holding LP, and therefore, such unitholder's foreign tax credits for Canadian federal income tax purposes, will be limited. See Item 10.E "Taxation—Certain Material Canadian Federal Income Tax Considerations".

         Unitholders who are not and are not deemed to be resident in Canada for purposes of the Tax Act and who do not use or hold, and are not deemed to use or hold, their units of our partnership in connection with a business carried on in Canada ("non-Canadian limited partners"), may be subject to Canadian federal income tax with respect to any Canadian source business income earned by our partnership or the Holding LP if our partnership or the Holding LP were considered to carry on business in Canada.

        If our partnership or the Holding LP were considered to carry on business in Canada for purposes of the Tax Act, non-Canadian limited partners would be subject to Canadian federal income tax on their proportionate share of any Canadian source business income earned or considered to be earned by our partnership, subject to the potential application of the safe harbour rule in section 115.2 of the Tax Act and any relief that may be provided by any relevant income tax treaty or convention.

        Our General Partner intends to manage the affairs of our partnership and the Holding LP, to the extent possible, so that they do not carry on business in Canada and are not considered or deemed to carry on business in Canada for purposes of the Tax Act. Nevertheless, because the determination of whether our partnership or the Holding LP is carrying on business and, if so, whether that business is carried on in Canada, is a question of fact that is dependent upon the surrounding circumstances, the CRA might contend successfully that either or both of our partnership and the Holding LP carries on business in Canada for purposes of the Tax Act.

        If our partnership or the Holding LP is considered to carry on business in Canada or is deemed to carry on business in Canada for the purposes of the Tax Act, non-Canadian limited partners that are corporations would be required to file a Canadian federal income tax return for each taxation year in which they are a non-Canadian limited partner regardless of whether relief from Canadian taxation is available under an applicable income tax treaty or convention. Non-Canadian limited partners who are individuals would only be required to file a Canadian federal income tax return for any taxation year in which they are allocated income from our partnership from carrying on business in Canada that is not exempt from Canadian taxation under the terms of an applicable income tax treaty or convention.

         Non-Canadian limited partners may be subject to Canadian federal income tax on capital gains realized by our partnership or the Holding LP on dispositions of "taxable Canadian property" (as defined in the Tax Act).

        A non-Canadian limited partner will be subject to Canadian federal income tax on its proportionate share of capital gains realized by our partnership or the Holding LP on the disposition of "taxable Canadian property" other than "treaty-protected property" (as defined in the Tax Act). "Taxable Canadian property" includes, but is not limited to, property that is used or held in a business carried on in Canada and shares of corporations that are not listed on a "designated stock exchange" (as defined in the Tax Act) if more than 50% of the fair market value of the shares is derived from certain Canadian properties during the 60-month period immediately preceding the particular time. Property of our partnership and the Holding LP generally will be "treaty-protected property" to a non-Canadian limited partner if the gain from the disposition of the property would, because of an applicable income tax treaty or convention, be exempt from tax under the Tax Act. Our General Partner does not expect our partnership or the Holding LP to realize capital gains or losses from dispositions of "taxable Canadian property". However, no assurance can be given in this regard. Non-Canadian limited partners will be required to file a Canadian federal income tax return in respect of a disposition of "taxable Canadian property" by our partnership or the Holding LP unless the disposition is an "excluded disposition" for the purposes of section 150 of the Tax Act. However, non-Canadian limited partners that are corporations will still be required to file a Canadian federal income tax return in respect of a disposition of "taxable Canadian property" that is an "excluded disposition" for the purposes of section 150 of the Tax Act if tax would otherwise be payable under Part I of the Tax Act by the non-Canadian limited partners in respect of the disposition but is not because of an applicable income tax treaty or convention (otherwise than in respect of a disposition of "taxable Canadian property" that is "treaty-protected property" of the corporation). In general, an "excluded disposition" is a disposition of property by a taxpayer in a taxation year where (a) the taxpayer is a non-resident of Canada at the time of the disposition; (b) no tax is payable by the taxpayer under Part I of the Tax Act for the taxation year; (c) the taxpayer is not liable to pay any amounts under the Tax Act in respect of any previous taxation year (other than certain amounts for which the CRA holds adequate security); and (d) each "taxable Canadian property" disposed of by the taxpayer in the taxation year is either (i) "excluded property" (as defined in subsection 116(6) of the Tax Act) or (ii) property in respect of the disposition of which a certificate under subsection 116(2), (4) or (5.2) of the Tax Act has been issued by the CRA. Non-Canadian limited partners should consult their own tax advisors with respect to the requirements to file a Canadian federal income tax return in respect of a disposition of "taxable Canadian property" by our partnership or the Holding LP.

         Non-Canadian limited partners may be subject to Canadian federal income tax on capital gains realized on the disposition of our units if our units are "taxable Canadian property".

        Any capital gain arising from the disposition or deemed disposition of our units by a non-Canadian limited partner will be subject to taxation in Canada, if, at the time of the disposition or deemed disposition, our units are "taxable Canadian property" of the non-Canadian limited partner, unless our units are "treaty-protected property" to such non-Canadian limited partner. In general, our units will not constitute "taxable Canadian property" of any non-Canadian limited partner at the time of disposition or deemed disposition, unless (a) at any time in the 60-month period immediately preceding the disposition or deemed disposition, more than 50% of the fair market value of our units was derived, directly or indirectly (excluding through a corporation, partnership or trust, the shares or interests in which were not themselves "taxable Canadian property"), from one or any combination of (i) real or immovable property situated in Canada; (ii) "Canadian resource properties" (as defined in the Tax Act); (iii) "timber resource properties" (as defined in the Tax Act); and (iv) options in respect of, or interests in, or for civil law rights in, such property, whether or not such property exists, or (b) our units are otherwise deemed to be "taxable Canadian property". Since our partnership's assets will consist principally of units of the Holding LP, our units would generally be "taxable Canadian property" at a particular time if the units of the Holding LP held by our partnership derived, directly or indirectly (excluding through a corporation, partnership or trust, the shares or interests in which were not themselves "taxable Canadian property") more than 50% of their fair market value from properties described in (i) to (iv) above, at any time in the 60-month period preceding the particular time. Our General Partner does not expect our units to be "taxable Canadian property" of any non-Canadian limited partner at any time but no assurance can be given in this regard. See Item 10.E "Taxation—Certain Material Canadian Federal Income Tax Considerations". Even if our units constitute "taxable Canadian property", our units will be "treaty-protected property" if the gain on the disposition of our units is exempt from tax under the Tax Act under the terms of an applicable income tax treaty or convention. If our units constitute "taxable Canadian property", non-Canadian limited partners will be required to file a Canadian federal income tax return in respect of a disposition of our units unless the disposition is an "excluded disposition" (as discussed above). If our units constitute "taxable Canadian property", non-Canadian limited partners should consult their own tax advisors with respect to the requirement to file a Canadian federal income tax return in respect of a disposition of our units.

         Non-Canadian limited partners may be subject to Canadian federal income tax reporting and withholding tax requirements on the disposition of "taxable Canadian property".

        Non-Canadian limited partners who dispose of "taxable Canadian property", other than "excluded property" and certain other property described in subsection 116(5.2) of the Tax Act, (or who are considered to have disposed of such property on the disposition of such property by our partnership or the Holding LP), are obligated to comply with the procedures set out in section 116 of the Tax Act and obtain a certificate pursuant to the Tax Act. In order to obtain such certificate, the non-Canadian limited partner is required to report certain particulars relating to the transaction to CRA not later than 10 days after the disposition occurs. Our General Partner does not expect our units to be "taxable Canadian property" of any non-Canadian limited partner and does not expect our partnership or the Holding LP to dispose of property that is "taxable Canadian property" but no assurance can be given in these regards.

         Payments of dividends or interest (other than interest not subject to Canadian federal withholding tax) by residents of Canada to the Holding LP will be subject to Canadian federal withholding tax and we may be unable to apply a reduced rate taking into account the residency or entitlement to relief under an applicable income tax treaty or convention of our unitholders.

        Our partnership and the Holding LP will be deemed to be a non-resident person in respect of certain amounts paid or credited or deemed to be paid or credited to them by a person resident or deemed to be resident in Canada, including dividends or interest. Dividends or interest (other than interest not subject to Canadian federal withholding tax) paid or deemed to be paid by a person resident or deemed to be resident in Canada to the Holding LP will be subject to withholding tax under Part XIII of the Tax Act at the rate of 25%. However, the CRA's administrative practice in similar circumstances is to permit the rate of Canadian federal withholding tax applicable to such payments to be computed by looking through the partnership and taking into account the residency of the partners (including partners who are resident in Canada) and any reduced rates of Canadian federal withholding tax that any non-Canadian limited partners may be entitled to under an applicable income tax treaty or convention, provided that the residency status and entitlement to treaty benefits can be established. In determining the rate of Canadian federal withholding tax applicable to amounts paid by the Holding Entities to the Holding LP, our General Partner expects the Holding Entities to look-through the Holding LP and our partnership to the residency of the partners of our partnership (including partners who are resident in Canada) and to take into account any reduced rates of Canadian federal withholding tax that non-Canadian limited partners may be entitled to under an applicable income tax treaty or convention in order to determine the appropriate amount of Canadian federal withholding tax to withhold from dividends or interest paid to the Holding LP. However, there can be no assurance that the CRA will apply its administrative practice in this context. If the CRA's administrative practice is not applied and the Holding Entities withhold Canadian federal withholding tax from applicable payments on a look-through basis, the Holding Entities may be liable for additional amounts of Canadian federal withholding tax plus any associated interest and penalties. Under the Canada-United States Tax Convention (1980) (the "Treaty"), a Canadian-resident payer is required in certain circumstances to look-through fiscally transparent partnerships, such as our partnership, and the Holding LP to the residency and Treaty entitlements of their partners and take into account the reduced rates of Canadian federal withholding tax that such partners may be entitled to under the Treaty.

        While our General Partner expects the Holding Entities to look-through our partnership and the Holding LP in determining the rate of Canadian federal withholding tax applicable to amounts paid or deemed to be paid by the Holding Entities to the Holding LP, we may be unable to accurately or timely determine the residency of our unitholders for purposes of establishing the extent to which Canadian federal withholding taxes apply or whether reduced rates of withholding tax apply to some or all of our unitholders. In such a case, the Holding Entities will withhold Canadian federal withholding tax from all payments made to the Holding LP that are subject to Canadian federal withholding tax at the rate of 25%. Canadian-resident unitholders will be entitled to claim a credit for such taxes against their Canadian federal income tax liability but non-Canadian limited partners will need to take certain steps to receive a refund or credit in respect of any such Canadian federal withholding taxes withheld equal to the difference between the withholding tax at a rate of 25% and the withholding tax at the reduced rate they are entitled to under an applicable income tax treaty or convention. See Item 10.E "Taxation—Certain Material Canadian Federal Income Tax Considerations" for further detail. Unitholders should consult their own tax advisors concerning all aspects of Canadian federal withholding taxes.

         Our units may or may not continue to be "qualified investments" under the Tax Act for registered plans.

        Provided that our units are listed on a "designated stock exchange" (which includes the NYSE and the TSX), our units will be "qualified investments" under the Tax Act for a trust governed by a registered retirement savings plan ("RRSP"), deferred profit sharing plan, registered retirement income fund ("RRIF"), registered education savings plan, registered disability savings plan, and a tax-free savings account ("TFSA"). However, there can be no assurance that our units will continue to be listed on a "designated stock exchange". There can also be no assurance that tax laws relating to "qualified investments" will not be changed. Taxes may be imposed in respect of the acquisition or holding of non-qualified investments by such registered plans and certain other taxpayers and with respect to the acquisition or holding of "prohibited investments" (as defined in the Tax Act) by an RRSP, RRIF or TFSA.

        Notwithstanding the foregoing, an annuitant under an RRSP or RRIF or a holder of a TFSA, as the case may be, will be subject to a penalty tax if our units held in an RRSP, RRIF or TFSA are "prohibited investments" for the RRSP, RRIF or TFSA, as the case may be. Generally, our units will not be a "prohibited investment" for a trust governed by an RRSP, RRIF or TFSA, provided that the annuitant under the RRSP or RRIF or the holder of the TFSA, as the case may be, deals at arm's length with our partnership for purposes of the Tax Act and does not have a "significant interest" (as defined in the Tax Act for purposes of the prohibited investment rules) in our partnership. Unitholders who will hold our units in an RRSP, RRIF or TFSA should consult with their own tax advisors regarding the application of the foregoing prohibited investment rules having regard to their particular circumstances.

         The Canadian federal income tax consequences to our unitholders could be materially different in certain respects from those described in this Form 20-F if our partnership or the Holding LP is a "SIFT partnership" (as defined in the Tax Act).

        Under the rules in the Tax Act applicable to a "SIFT partnership" (the "SIFT Rules"), certain income and gains earned by a "SIFT partnership" will be subject to income tax at the partnership level at a rate similar to a corporation, and allocations of such income and gains to its partners will be taxed as a dividend from a "taxable Canadian corporation" (as defined in the Tax Act). In particular, a "SIFT partnership" will be required to pay a tax on the total of its income from businesses carried on in Canada, income from "non-portfolio properties" (as defined in the Tax Act) other than taxable dividends, and taxable capital gains from dispositions of "non-portfolio properties". "Non-portfolio properties" include, among other things, equity interests or debt of corporations, trusts or partnerships that are resident in Canada, and of non-resident persons or partnerships the principal source of income of which is one or any combination of sources in Canada (other than a "portfolio investment entity", as defined in the Tax Act), that are held by the "SIFT partnership" and have a fair market value that is greater than 10% of the equity value of such entity, or that have, together with debt or equity that the "SIFT partnership" holds of entities affiliated (within the meaning of the Tax Act) with such entity, an aggregate fair market value that is greater than 50% of the equity value of the "SIFT partnership". The tax rate that is applied to the above mentioned sources of income and gains is set at a rate equal to the "net corporate income tax rate", plus the "provincial SIFT tax rate" (each as defined in the Tax Act).

Table of Contents

        A partnership will be a "SIFT partnership" throughout a taxation year if at any time in the taxation year (i) it is a "Canadian resident partnership" (as defined in the Tax Act), (ii) "investments" (as defined in the Tax Act) in the partnership are listed or traded on a stock exchange or other public market, and (iii) it holds one or more "non-portfolio properties". For these purposes, a partnership will be a "Canadian resident partnership" at a particular time if (a) it is a "Canadian partnership" (as defined in the Tax Act) at that time, (b) it would, if it were a corporation, be resident in Canada (including, for greater certainty, a partnership that has its central management and control located in Canada), or (c) it was formed under the laws of a province. A "Canadian partnership" for these purposes is a partnership all of whose members are resident in Canada or are partnerships that are "Canadian partnerships".

        Under the SIFT Rules, our partnership and the Holding LP could each be a "SIFT partnership" if it is a "Canadian resident partnership". However, the Holding LP would not be a "SIFT partnership" if our partnership is a "SIFT partnership" regardless of whether the Holding LP is a "Canadian resident partnership" on the basis that the Holding LP would be an "excluded subsidiary entity" (as defined in the Tax Act). Our partnership and the Holding LP will be a "Canadian resident partnership" if the central management and control of these partnerships is located in Canada. This determination is a question of fact and is expected to depend on where our General Partner is located and exercises central management and control of the respective partnerships. Our General Partner will take appropriate steps so that the central management and control of these entities is not located in Canada such that the SIFT Rules should not apply to our partnership or the Holding LP at any relevant time. However, no assurance can be given in this regard. If our partnership or the Holding LP is a "SIFT partnership", the Canadian federal income tax consequences to our unitholders could be materially different in certain respects from those described in Item 10.E. "Taxation—Certain Material Canadian Federal Income Tax Considerations". In addition, there can be no assurance that the SIFT Rules will not be revised or amended in the future such that the SIFT Rules will apply.
