Unless otherwise specified, information provided in this annual report on Form 20-F is as of December 31, 2010.

Unless the context requires otherwise, when used in this annual report on Form 20-F, the terms "Brookfield Infrastructure", "we", "us" and "our" refer to Brookfield Infrastructure Partners L.P., collectively with its subsidiary entities and the operating entities (as defined below). All dollar amounts contained in this annual report on Form 20-F are expressed in U.S. dollars and references to "dollars", "$", "US$" or "USD" are to U.S. dollars, all references to "C$" or "CAD" are to Canadian dollars, and all references to "A$" are to Australian dollars. In addition, all references to "£" or "GBP" are to pound sterling, all references to "NZD" are to New Zealand dollars, all references to "€" or "EUR" are to Euros, and unless the context suggests otherwise, references to:

This annual report on Form 20-F contains certain forward-looking statements and information concerning our business and operations. The forward-looking statements and information also relate to, among other things, our objectives, goals, strategies, intentions, plans, beliefs, expectations and estimates and anticipated events or trends. In some cases, you can identify forward-looking statements by terms such as "anticipate," "believe," "could," "estimate," "expect," "intend," "may," "plan," "potential," "should," "will" and "would" or the negative of those terms or other comparable terminology.

Although we believe that our anticipated future results, performance or achievements expressed or implied by the forward-looking statements and information are based on reasonable assumptions and expectations, the reader should not place undue reliance on forward-looking statements and information because they involve assumptions, known and unknown risks, uncertainties and other factors which may cause our actual results, performance or achievements to differ materially from anticipated future results, performance or achievements expressed or implied by the forward-looking statements and information.

The following factors could cause our actual results to differ materially from our forward looking statements and information:

In light of these risks, uncertainties and assumptions, the events described by our forward-looking statements and information might not occur. We qualify any and all of our forward-looking statements and information by these cautionary factors. Please keep this cautionary note in mind as you read this annual report on Form 20-F. We disclaim any obligation to update or revise publicly any forward-looking statements or information, whether as a result of new information, future events or otherwise, except as required by applicable law.

To measure performance, we focus on net income as well as funds from operations, or FFO.

We define FFO as net income excluding the impact of depreciation, depletion and amortization, deferred taxes and other items. FFO is a measure of operating performance, which is not calculated in accordance with, and does not have any standardized meaning prescribed by, International Financial Reporting Standards, or IFRS. FFO is therefore unlikely to be comparable to similar measures presented by other issuers. FFO has limitations as an analytical tool. See Item 5 "Operating and Financial Review and Prospects—Reconciliation of Non-IFRS Financial Measures" for more information on this measure, including a reconciliation to the most directly comparable IFRS measure.

In addition, we use adjusted funds from operations, or AFFO, as a measure of long-term sustainable cash flow.

We define adjusted funds from operations, or AFFO, as funds from operations (FFO) less maintenance capital expenditures. AFFO is a measure of operating performance, which is not calculated in accordance with, and does not have any standardized meaning prescribed by International Financial Reporting Standards, or IFRS. AFFO is therefore unlikely to be comparable to similar measures presented by other issuers. AFFO has limitations as an analytical tool. See Item 5 "Operating and Financial Review and Prospects—Reconciliation of Non-IFRS Financial Measures" for more information on this measure, including a reconciliation to the most directly comparable IFRS measure.

In addition, we focus on "EBITDA", which we define as earnings before interest, taxes, depreciation and amortization. Like FFO, EBITDA is a measure of operating performance, which is not calculated in accordance with, and does not have any standardized meaning prescribed by IFRS. EBITDA is therefore unlikely to be comparable to similar measures presented by other issuers. EBITDA has limitations as an analytical tool. See Item 5 "Operating and Financial Review and

Prospects" for more information on this measure, including a reconciliation to the most directly comparable IFRS Measure.

We define invested capital as Partnership capital adding back the following items: maintenance capital expenditures, non-cash income statement items and other comprehensive income. Invested capital is a measure that is not calculated in accordance with, and does not have any standardized meaning prescribed by IFRS. Invested Capital is therefore unlikely to be comparable to similar measures presented by other issuers. Invested Capital has limitations as an analytical tool. See Item 5 "Operating and Financial Review and Prospects—Reconciliation of Non-IFRS Financial Measures" for more information on this measure, including a reconciliation to the most directly comparable IFRS measure.

(1): Funds from operations (FFO) is defined as net income excluding the impact of depreciation, depletion and amortization, deferred taxes and other items. FFO is a measure of operating performance that is not calculated in accordance with, and does not have any standardized meaning prescribed by IFRS. Please see Item 5 "Operating and Financial Review and Prospects—Management's Discussion and Analysis of Financial Condition and Results of Operations—Reconciliation of Non-IFRS Financial Measures" for a discussion of FFO and its limitations as a measure of our operating performance.
(2): Excluding $68 million gain on sale of Transmissoras Brasileiras de Energia, or TBE in 2009.
(3): Brookfield Infrastructure prepared its first annual consolidated and combined financial statements in accordance with IFRS for the years ended December 31, 2010 and 2009. Brookfield Infrastructure's consolidated and combined financial statements were prepared in accordance with IFRS 1 First-time Adoption of International Financial Reporting Standards. Prior to the adoption of IFRS Brookfield Infrastructure prepared its financial statements in accordance with U.S. Generally Accepted Accounting Principles. Brookfield Infrastructure's transition date is January 1, 2009, or the transition date, and Brookfield Infrastructure has prepared its opening IFRS Statements of Financial Position as of that date.

Effective December 31, 2010, our partnership entered into voting arrangements with various affiliates of Brookfield whereby our partnership effectively gained control of the Holding LP, as well as Brookfield's holdings in our timber operations, Australian coal terminal and UK port operations, subject to certain limitations. Our partnership, therefore, utilizes the consolidation method of accounting for all businesses except for our North American gas transmission operations, our South American electricity transmission operations, our Australian distribution business and our European port operations which are accounted for using the equity method. As this reorganization does not represent a business combination under IFRS 3 Business Combinations, the consolidated financial statements of Brookfield Infrastructure as of and for the years ended December 31, 2010 and 2009 are presented to reflect continuation of control. Therefore, the consolidated and combined statements of financial position, and results of operations are presented as if these arrangements had been in place from the time our partnership acquired control (See note 3 of Brookfield Infrastructure notes to the consolidated and combined financial statements for a more detailed description).

The following is non-IFRS financial information for Brookfield Infrastructure for the periods indicated:

You should carefully consider the following factors in addition to the other information set forth in this annual report on Form 20-F. If any of the following risks actually occur, our business, financial condition and results of operations and the value of our unitholders' units would likely suffer.

The completion of the Merger Transaction has significantly increased the scale and scope of our operations, including operations in new geographic areas and industry segments, and our Manager may have difficulty managing these additional operations.

The Merger Transaction has significantly increased the scale and scope of our operations. We depend on the diligence and skill of Brookfield's professionals to manage us, including integrating all of Prime's 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.

Our assets are or may become highly leveraged and we may incur indebtedness in addition to asset-level indebtedness under our current or future credit facility or other debt or debt-like instruments, which contain certain restrictive covenants, or otherwise.

Our operating entities have a significant degree of leverage on their assets, including acquisition-related leverage, which is not reflected in our historical financial statements. In addition, we may increase the leverage on our assets. 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 liquidity, which forces the sale of assets at times of low demand and/or prices for such assets. This may mean that we are unable to sell an asset or unable to realize fair value for the assets in a sale.

We may also incur indebtedness under existing and future credit facilities, or other debt-like instruments in addition to any asset-level indebtedness. We may also issue debt or debt-like instruments in the market in the future, which may or may not be rated. Should such debt or debt-like instruments be rated, a credit downgrade will have an adverse impact on the cost of such debt.

The terms of our senior secured credit facility subject us to financial and operating covenants, which restrict our ability to engage in certain types of activities and make distributions in respect of equity.

In 2010, the Holding LP and certain of its subsidiaries entered into a credit agreement with Royal Bank of Canada as administrative agent with an available commitment of $700 million, maturing in June 2013. This facility may be used for acquisitions and investments in eligible assets as well as general corporate purposes. Drawings under this facility for acquisitions and investments are subject to satisfaction of certain conditions, including compliance with certain financial ratios. Drawings for general corporate purposes are not subject to compliance with these financial ratios. This facility is also subject to negative covenants applicable to the Holding LP and its "restricted subsidiaries" and events of default that, in each case, are believed to be customary for loans of this type, including limitations on financial indebtedness, liens, dividends, investments, minimum net worth, and when credit extensions under the facility exceed 50% of the then effective commitment, a minimum interest coverage ratio.

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 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.

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 the rules thereunder (and similar legislation in other jurisdictions) provide certain protections to investors and impose certain restrictions on companies that are registered 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 would potentially cause our partnership to be deemed an investment company under the Investment Company Act, it would be impractical for us to operate as intended. 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 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. 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.

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, or the 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 continuous disclosure obligations and proxy solicitation if our partnership complies with certain reporting requirements applicable in the United States, provided that the relevant documents filed with the U.S. Securities Exchange

Commission, or the SEC, are filed in Canada and sent to our partnership's security holders in Canada to the extent and in the manner and within the time required by applicable U.S. requirements. 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, as amended, or the 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 United States. 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.

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.

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, our management is required to deliver a report that assesses the effectiveness of our internal controls over financial reporting and our independent registered public accounting firm is required to deliver an attestation report on our management's assessment of, and the operating effectiveness of, our internal controls over financial reporting in conjunction with their opinion on our audited financial statements. 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 a more than remote possibility of errors or misstatements in our consolidated financial statements that would 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 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.

All of our operating entities are subject to general economic conditions and risks relating to the global economy.

Many industries, including the industries in which we operate, are impacted by adverse events in global financial markets, which may have a profound effect on global 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, including, but not limited to, new home construction, employment rates, business conditions, inflation, fuel and energy costs, 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 the operations are, in part, dependent upon and correlated to economic growth of the regions applicable to the assets and the demand for services sought by the customers of the relevant assets. Lower economic growth in a region or regions may, either directly or indirectly, reduce demand for the services provided by the assets.

Specifically, a global credit/liquidity crisis, such as the one 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; and the devaluation and volatility of global stock markets could materially impact the valuation of our 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 continue, our operations and the trading price of our units may be adversely impacted.

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

Some of our operations are critically linked to the transport or production of key commodities. For example, in the long term, our Australian coal terminal operation relies on demand for coal exports and our North American gas transmission operation relies on demand for natural gas and benefits from higher gas prices. Similarly, our timber operations rely on strong demand for timber products. Accordingly, a downturn in the demand for or price of a key commodity linked to one of our operations may have a material adverse impact on the financial performance or growth prospects of that particular operation.

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

General economic and business conditions that impact the debt or equity markets could impact Brookfield Infrastructure's ability to access credit markets.

General economic and business conditions that impact the debt or equity markets, such as the 2008/2009 global financial crisis, could impact the availability of credit to, and cost of credit for, Brookfield Infrastructure. Brookfield Infrastructure has 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 Brookfield Infrastructure's financial condition.

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 example, our Australian railroad operations. 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 Brookfield Infrastructure is unable to generate enough cash to finance necessary capital expenditure through operating cash flow, then Brookfield Infrastructure may be required to issue additional equity or incur additional indebtedness. The issue of additional equity would be dilutive to existing shareholders at the time and any additional indebtedness would increase the debt payment obligations of Brookfield Infrastructure, and may negatively impact its business, financial condition and results of operations.

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 and concession agreements; interest rates; currency fluctuations; exchange controls and restrictions; inflation; liquidity of domestic financial and capital markets; tax policies; 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 operate or the countries in which the customers of our operating entities operate 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 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. 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.

The assets of our infrastructure businesses are exposed to unplanned interruptions caused by significant catastrophic events such as cyclones, landslides, explosions, terrorist attacks, floods, earthquakes, fires, major plant breakdowns, pipeline or electricity line ruptures 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 or penalties or regulatory or contractual non-compliance. Moreover, any loss from such events may not be recoverable under relevant insurance policies. Business interruption insurance is not always available, or economic, to protect the business from these risks.

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 acts of God, fire, flood, earthquakes, war and labor strikes. Some force majeure events may adversely affect a party's ability to perform its obligations until it is able to remedy the force majeure event.

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, our timber operations are not insured against losses from fires, many components of our South American electricity transmission operations are not insured against losses from earthquakes and our North American gas transmission operation, our Australasian energy distribution operations in New Zealand and our European energy 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 would be prohibitive. While not a risk borne directly by us, 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.

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

Our utilities and 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 addition, in some of the jurisdictions in which we have utilities or transport and 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 cover 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 labor disruptions and economically unfavorable collective bargaining agreements.

Several of our current operations or other business operations have workforces that are unionized and, as a result, they 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 labor 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, labor forces have a legal right to strike which may have an impact on our operations.

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

Infrastructure projects and operational assets are 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 ability 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 which do not amount to a breach, 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 outcomes.

Many of our utilities operations and transport and energy operations are regulated and may be exposed to increased economic regulation.

Our utilities operations and transport and energy operations involve ongoing commitments to economic regulators, safety regulators and other governmental agencies. This is due to the essential nature of the services provided by these businesses and the fact that the services are usually provided on a monopoly or near monopoly basis. The terms upon which access to our facilities is provided can be determined or amended by a regulator periodically. Future terms to apply, including access charges 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 regulatory determinations or changes in regulatory approaches may result in material changes to the revenue or profitability of our utilities operations and transport and energy 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 utilities operations and transport and energy 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, reliability or quality of service. In addition, a decision by a government or regulator to regulate non-regulated assets may significantly change the economics of these businesses.

Our operating entities are exposed to environmental risks, including 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. Specifically, many jurisdictions in which Brookfield Infrastructure operates are considering implementing, or have implemented, schemes relating to the regulation of carbon emissions. 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.

It is difficult to assess the impact of any changes on Brookfield Infrastructure. These schemes may result in increased costs to our operations and may have an adverse impact on prospects for growth of some businesses. To the extent such regimes (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 and 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, our timber operations are subject to provincial, state and federal government regulations relating to forestry practices and the export of logs and several of our utilities and 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.

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

Our utilities, transport and energy and timber 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 easements, licenses and rights of way necessary 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 rights to land and the existence or declaration of native title may affect the existing or future activities of our utilities, transport and energy or timber operations and impact on their business, financial condition and results of operations.

In addition, a government, court, regulator, 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, 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.

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. 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 assure you 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 in the future 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.

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 its 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.

In addition, there is a risk that when the Brookfield Infrastructure participates with Brookfield and others in joint ventures, partnerships and consortiums on acquisitions, Brookfield Infrastructure may become subject to anti-trust or competition laws that it would not be subject to if it were acting alone. These factors may create competitive disadvantages for the Brookfield Infrastructure with respect to acquisition opportunities.

Investments in infrastructure projects during the construction phase are likely to retain some residual risk.

Investments in new infrastructure projects during the construction phase are likely to retain some residual risk that the project 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, the 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 labor, material expenses, and a resultant delay in the commencement of cash flow; and (ii) the insolvency of the head contractor, a major subcontractor and/or a key equipment supplier. Construction costs may exceed estimates for various reasons, including inaccurate engineering and planning, labor and building material costs in excess of expectations and unanticipated problems with project start-up. Such unexpected increases may result in increased debt service costs, operations phase 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.

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

Brookfield has structured some of our current operations 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.

Joint ventures, partnerships and consortium investments generally provide for a reduced level of control 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, are often made by a majority vote of the investors or by separate agreements that are reached with respect to individual decisions. 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 not have the ability to exercise control 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 current operations are structured as joint ventures, partnerships or consortium arrangements, the sale or transfer of interests in some of our operations are 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 an en bloc 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 businesses are at risk of becoming involved in disputes and possible litigation, the extent of which cannot be ascertained at this time. 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. Further information regarding specific disputes is provided below.

Future 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; 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 labor, commercial or regulatory disputes or litigation related to the new enterprise; and the risk of environmental or other liabilities associated with the acquired business.

There are a variety of risks relating to the public private partnerships of Brookfield Infrastructure, including:

Change of control provisions as a result of the merger between Brookfield Infrastructure and Prime.

A change of control in Prime resulting from the Merger Transaction may trigger rights by third parties or government agencies under contracts with, or authorizations held by Prime or the operating businesses held by it. We are aware of a number of such provisions, but we do not believe any of these provisions are material. It is possible that due diligence conducted as part of the Merger Transaction may have failed 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.

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 experience 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.

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 licences 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, licences, permits or approvals (or applications for licences, 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 places significant reliance on information technology. Its computer systems will include custom developed and purchased business applications, both for information and processing, as well as embedded systems, which support ongoing administrative and commercial operations. 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. The failure of any such systems for a significant time period could have a material adverse effect on our business prospects, financial condition and results of operations.

Clients of our utilities operations may default on their obligations under the relevant contractual arrangements.

Some of our utilities operations have customer contracts as well as concession agreements in place with public and private sector clients. On the public sector side this may include central government departments, local government bodies and quasi-government agencies. Since it cannot be assumed that a central government will in all cases assume liability for the obligation of quasi-government agencies or those central government departments will themselves not default on their obligations, the possibility of a default remains. Our utilities operations also have contracts with private sector clients. There is an increased risk of default by private sector clients compared with public sector clients. For example, we have a single customer which represented approximately 63% of contractual and regulated revenues of our South American electricity transmission operations in 2010. 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 assets, financial condition or results of operations of that customer.

Customers of our transport and energy operations may default on their obligations under the relevant contractual arrangements.

Our transport and energy operations have a broad portfolio of customers, however should any of our customers experience financial problems it may have a significant impact on their creditworthiness. We cannot provide assurance that one or more of these 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 transport and energy 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.

The financial performance of our timber operations may be affected by economic recessions or downturns.

The vast majority of the products from our timber operations are sensitive to macro-economic conditions in North America and Asia and are thus susceptible to economic recessions or downturns in these markets. Decreases in the level of residential construction, repair and remodeling activity generally reduce demand for logs and wood products, resulting in lower revenues, profits and cash flows for lumber mills who are important customers to our timber operations. Depressed commodity prices in lumber, pulp or paper may also cause mill operators to temporarily or permanently shut down their mills if their product prices fall to a level where mill operation would be uneconomic. Moreover, these operators may be required to temporarily suspend operations at one or more of their mills to bring production in line with market demand or in response to market irregularities. Any of these circumstances could significantly reduce the prices that we realize for our timber as well as the volume of our timber that we may be able to sell. In addition to impacting our timber operations' sales, cash flows and earnings, weakness in the market prices of timber products will also have an effect on our ability to attract additional capital, the cost of that capital and the value of our timberland assets. Further, we may reduce near term harvest levels to preserve our inventory for periods of higher pricing, which would negatively impact the near term results and cash flow of our timber operations.

A variety of factors may limit or prevent harvesting by our timber operations, including weather conditions.

Weather conditions, industry practices and federal, state and provincial laws and regulations associated with forestry practices, sale of logs and environmental matters, including wildlife and water resources, may limit or prevent harvesting, road building and other activities on the timberlands owned by our timber operations. In the case of restrictions arising from regulatory requirements, the size of the area subject to restriction will vary depending on the protected species at issue, the time of year and other factors. In addition, if regulations become more restrictive, the amount of the timberlands subject to harvest restrictions could increase. The timberlands owned by our timber operations may also suffer damage by fire, insect infestation, wind, disease, prolonged drought and other natural and man-made disasters. There can be no assurance that our timber operations will achieve harvest levels in the future necessary to maintain or increase revenues, earnings and cash flows. There can be no assurance that the forest management planning by our timber operations, including silviculture, will have the intended result of ensuring that their asset base appreciates over time.

Our timber operations operate in a highly competitive industry, subject to price fluctuations.

Timberland companies operate in a highly competitive business environment in which companies compete, to a large degree, on the basis of price and also on the basis of service and ability to provide a steady supply of products over the long-term. The prime competitors to our timber operations are governments, other large forestland owners and small private forestland owners. In addition, wood and paper products are subject to increasing competition from a variety of substitute products, including non-wood and engineered wood products and electronic media. The competitive position of our timber operations and the price realized for our products is also influenced by a number of other factors including: the ability to attract and maintain long-term customer relationships; the quality of our products; the health of the regional converting industry; the costs of timber production; the availability, quality and cost of labor; the cost of fuel; shipping and fee for service costs; changes in global timber supply; technological advances that increase yield in other regions; and the price and availability of substitute wood and non-wood products.

Our Canadian timber operations are subject to federal restrictions which may require them to decrease their planned export of logs.

Currently, logs from most private timberlands in Canada are not subject to provincial export regulations, but are subject to federal export regulations. As a result, all export logs must be advertised for local consumption and may be exported only if there is a surplus of domestic supply as indicated by the absence of fair market value offers (based on current domestic prices) from domestic lumber mills. Accordingly, an increase in domestic demand could result in our Canadian freehold timberlands being required to decrease their planned export of logs. The provincial government in British Columbia is currently reviewing its log export policy, and may recommend that the federal government impose a policy that may further restrict the export of logs from private lands in British Columbia. As export market pricing is generally at a premium to the domestic market pricing, any reduction in log exports could have an adverse effect on our Canadian timber operations.

Further risks arising from changes to legislation or regulations affecting Timberlands may arise from:

In addition, Timberlands may be adversely affected by infestations such as the pine beetle which has had a material impact on the pine species in the interior of the United States and Canada.

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

Brookfield is the sole shareholder of our Managing General Partner. As a result of its ownership of our Managing General Partner, Brookfield is able to control the appointment and removal of our Managing General Partner's directors and, accordingly, exercise substantial influence over our partnership. In addition, our partnership holds its interest in the operating entities indirectly and will hold any future acquisitions indirectly through the Holding LP, the general partner of which is indirectly owned by Brookfield. As our partnership's only substantial asset is the limited partnership interests that it holds in the Holding LP, our partnership does not have a right to participate directly in the management or activities of the Holding LP or the Holding Entities, including with respect to the making of decisions.

Our partnership and Holding LP do not have any employees and depend on the management and administration services provided by the Manager. 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:

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 Managing General Partner may be transferred to a third party without unitholder consent.

Our Managing 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. Furthermore, at any time, the shareholder of our Managing General Partner may sell or transfer all or part of its shares in our Managing General Partner without the approval of our unitholders. If a new owner were to acquire ownership of our Managing 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 Managing General Partner would have on the trading price of our 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.

Brookfield may increase its ownership of our partnership and the Holding LP relative to other unitholders.

Brookfield holds approximately 29% of the issued and outstanding interests in the Holding LP through a 1% general partnership interest and a 28% limited partnership interest. The limited partnership interests held by Brookfield are redeemable for cash or exchangeable for our units in accordance with the Redemption-Exchange Mechanism, which could result in Brookfield eventually owning 29% of our issued and outstanding units. See Item 10.B "Memorandum and Articles of Association—Description of the Holding LP's Limited Partnership Agreement—Redemption-Exchange Mechanism." Brookfield currently owns approximately 2% of our issued and outstanding units.

The Infrastructure GP LP may also reinvest incentive distributions in exchange for units of the Holding LP. See Item 7.B "Related Party Transactions—Incentive Distributions." In addition, Brookfield has advised our partnership that it may from time-to-time reinvest distributions it receives from the Holding LP in the Holding LP's distribution reinvestment plan, with the result that Brookfield will receive additional units of the Holding LP. Additional units of the Holding LP acquired, directly or indirectly, by Brookfield 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." Brookfield may also purchase additional units of our partnership in the market. Any of these events may result in Brookfield increasing its ownership of our partnership and the Holding LP above 50%.

Brookfield does not owe our unitholders any fiduciary duties under the Master Services Agreement or our other arrangements with Brookfield.

The obligations of Brookfield under the Master Services Agreement and our other arrangements with them are contractual rather than fiduciary in nature. As a result, our Managing General Partner, which is an affiliate of Brookfield, in its capacity as our partnership's general partner, has sole authority and discretion to enforce the terms of such agreements and to consent to any waiver, modification or amendment of their provisions.

Our limited partnership agreement and the Holding LP's limited partnership agreement contain various provisions that modify the fiduciary duties that might otherwise be owed to our partnership and our unitholders, including when such conflicts of interest arise. These modifications may be important to our unitholders because they restrict the remedies available for actions that might otherwise constitute a breach of fiduciary duty and permit our Managing General Partner and the Infrastructure General Partner to take into account the interests of third parties, including Brookfield, when resolving conflicts of interest. See Item 7.B "Related Party Transactions—Conflicts of Interest and Fiduciary Duties." It is possible that conflicts of interest may be resolved in a manner that is not in the best interests of our partnership or the best interests of our unitholders.

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.

Our organizational and ownership structure involves a number of relationships that may give rise to conflicts of interest between our partnership and our 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 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."

Our arrangements with Brookfield were negotiated in the context of an affiliated relationship and may contain terms that are less favorable 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 Managing 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 favorable than otherwise might have resulted if the negotiations had involved unrelated parties. Under our limited partnership agreement, persons who acquire our 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 Managing 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 Manager 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 Manager; the Manager engages in any act of fraud, misappropriation of funds or embezzlement against any Service Recipient that results in material harm to us; the Manager 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 Manager. Our Managing General Partner cannot terminate the agreement for any other reason, including if the Manager or Brookfield experiences a change of control, and there is no fixed term to the agreement. In addition, because our Managing 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 Manager's performance does not meet the expectations of investors, and our Managing General Partner is unable or unwilling to terminate the Master Services Agreement, the market price of our units could suffer. Furthermore, the termination of the Master Services Agreement would terminate our partnership's rights under the Relationship Agreement and the Licensing Agreement. See Item 7.B "Related Party Transactions—Relationship Agreement" and Item 7.B "Related Party Transactions—Licensing Agreement."

The liability of the Manager is limited under our arrangements with it and we have agreed to indemnify the Manager 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 Manager 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 Managing General Partner takes in following or declining to follow its advice or recommendations. In addition, under our limited partnership agreement, the liability of the Managing General Partner and its affiliates, including the Manager, 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 Manager under the Master Services Agreement is similarly limited, except that the Manager is also liable for liabilities arising from gross negligence. In addition, our partnership has agreed to indemnify the Manager 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 Manager, 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 Manager 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 Manager is a party may also give rise to legal claims for indemnification that are adverse to our partnership and our unitholders.

Our 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 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 do not have the right to remove our Managing General Partner, to cause our Managing 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 Managing General Partner's board of directors, to remove existing directors from our Managing General Partner's board of directors or to prevent a change of control of our Managing General Partner. In addition, except as prescribed by applicable laws, our 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.

The market price of our 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 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; 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; 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; 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.

Changes in tax law and practice may have a material adverse effect on our operations 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 such company or entity, as well as the net amount of distributions payable to our unitholders. Taxes and other constraints that would be applicable to us in such jurisdictions may not be applicable 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.

In 2010, legislation was introduced into the U.S. Congress and passed by the U.S. House of Representatives (H.R. 4213, the American Jobs and Closing Tax Loopholes Act of 2010, or the Act), which, if it had been finally enacted into law and applicable to our partnership, could have had adverse consequences, including (a) the re-characterization of capital gain income as "ordinary income", (b) the potential reclassification of qualified dividend income as "ordinary income" subject to a higher rate of U.S. income tax, (c) uncertain treatment for non-U.S. partners on certain types of U.S. source income, and (d) significant limitations on the ability of our partnership to meet the "qualifying income" exception for taxation as a partnership for U.S. federal income tax purposes. However, such legislation was never passed by the U.S. Senate and was not enacted into law. Recently, President Obama has reintroduced as part of his fiscal year 2012 budget proposal a similar concept of re-characterizing certain items of capital gain income as "ordinary income", but such proposal lacks sufficient details to determine its full scope and any potential application to our partnership. At this time, it remains unclear whether any legislation related to such budget proposal, or legislation similar to H.R. 4213, will be proposed or enacted by the U.S. Congress and, if enacted, whether and how any such legislation would apply to our partnership. See discussion under Item 10.E "Taxation—Certain Material U.S. Federal Income Tax Considerations—Partnership Status of our partnership and the Holding LP". In view of the potential significance of any such U.S. federal income tax law changes and the fact that there are likely to be ongoing developments in this area, you should consult your own tax advisor as to the potential effects the proposed legislation might have on an investment in our partnership.

Additionally, under recently enacted U.S. legislation, certain payments of U.S. source income made after December 31, 2012, (including payments attributable to dispositions of property which produced (or could produce) certain U.S. source income) made to us or by us to or through non-U.S. financial institutions or non-U.S. entities, could be subject to a 30% withholding tax unless (a) the non-U.S. financial institution enters into an agreement with the IRS to provide to the IRS information concerning its direct and certain indirect U.S. account holders, or (b) in the case of other non-U.S. entities, such entity provides to the withholding agent similar information concerning its substantial U.S. beneficial owners. These rules do not apply with respect to payments from obligations that are outstanding as of March 18, 2012. You should consult your own tax advisors as to the potential effects the recently enacted legislation might have on an investment in our partnership.

Our partnership's ability to make distributions depends on us receiving sufficient cash distributions from our 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.

We are subject to local taxes in each of the relevant territories and jurisdictions (such as Canada, the United States, the United Kingdom, Australia and Chile) in which we have operations, including taxes on our income, profits or gains and withholding taxes. As a result, our partnership's cash available for distribution is reduced by such taxes and the post-tax return to investors is similarly reduced by such taxes. We intend that future acquisitions be assessed on a case-by-case basis and, where possible

and commercially viable, structured so as to minimize any adverse tax consequences for us as a result of making such acquisitions.

Each of our unitholders will be required to include in their income its allocable share of our partnership's items of income, gain, loss, deduction and credit (including, so long as it is treated as a partnership for tax purposes, our partnership's allocable share of those items of Brookfield Infrastructure) for each of our taxable years ending with or within such unitholder's taxable year. See Item 10.E "Taxation." With respect to each of our unitholders, the cash distributed to a unitholder may not be sufficient to fund the payment of the full amount of such unitholder's tax liability in respect of its investment in our partnership because such unitholder's tax liability is dependent on their particular tax situation and we will make simplifying tax assumptions in determining the amount of the distribution. In addition, the actual amount and timing of distributions will always be subject to the discretion of our Managing General Partner's board of directors and we cannot assure our unitholders that our partnership will in fact make cash distributions as intended. See Item 8.A "Consolidated Statements and Other Financial Information." Even if our partnership is unable to distribute cash in an amount that is sufficient to fund our unitholders tax liabilities, each of our unitholders will still be required to pay income taxes on their share of our partnership's taxable income.

Our unitholders may be subject to taxes and tax filing obligations in jurisdictions in which they are not resident for tax purposes or are not otherwise subject to tax.

Because of our unitholders' holdings in our partnership, our unitholders may be subject to taxes and tax return filing obligations in jurisdictions other than the jurisdiction in which they are a resident for tax purposes or are not otherwise subject to tax. Although we will attempt, to the extent reasonably practicable, to structure our operations and investments so as to minimize income tax filing obligations by our unitholders in such jurisdictions, there may be circumstances in which we are unable to do so. Income or gains from our holdings may be subject to withholding or other taxes in jurisdictions outside our unitholders' jurisdiction of residence for tax purposes or in which they are not otherwise subject to tax. If any of our unitholders wish to claim the benefit of an applicable income tax treaty, such unitholders may be required to submit information to our partnership and/or the tax authorities in such jurisdictions.

To the extent that our partnership, Brookfield Infrastructure, 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 received or paid 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 being paid by such entities and therefore the return to investors could be reduced.

Our Managing General Partner and the Infrastructure General Partner believe that the base management fee and any other amount that is paid to the Manager will be commensurate with the value of the services being provided by the Manager and are comparable to the fees or other amounts that would be agreed to in an arm's length arrangement. Our Managing General Partner and the Infrastructure General Partner therefore do not anticipate that the amounts of income (or loss) allocated to our unitholders will be adjusted. 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 (most likely, an expense) that is relevant to the computation of the income of Brookfield Infrastructure 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 may 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. Our Managing General Partner and the Infrastructure General Partner advise that satisfactory contemporaneous documentation for these purposes has been and will be prepared in respect of all transactions or arrangements with Brookfield, and in particular with respect to the Master Services Agreement. Accordingly, our Managing General Partner and the Infrastructure General Partner do not anticipate that the amounts of income (or loss) allocated to our unitholders for tax purposes will be required to be adjusted or that our unitholders, our partnership, or Brookfield Infrastructure will be subject to transfer pricing penalties described above. However, no assurance can be given in this regard.

A non-U.S. person who holds more than 5% of our units may be subject to special rules under the U.S. Foreign Investment in Real Property Tax Act of 1980, which may have a material adverse effect on the return to such person from an investment in our units.

A non-U.S. person who holds more than 5% of our units may be subject to special rules under the U.S. Foreign Investment in Real Property Tax Act of 1980, or FIRPTA. For purposes of determining whether a non-U.S. person holds more than 5% of our units, special attribution rules apply. Where a non-U.S. person who holds (or is deemed to hold) more than 5% of our units disposes of units at a time when our partnership is a U.S. Real Property Holding Corporation, or USRPHC, (which determination includes a five year look back period) any gain will be subject to U.S. taxation at 35%, and such non-U.S. person will have a U.S. tax return filing obligation. Our Managing General Partner does not believe that our partnership is currently, or has been, a USRPHC. Our partnership is not under any obligation to avoid becoming a USRPHC or to notify unitholders in the event that our Managing General Partner determines it becomes a USRPHC. If any unitholder is a non-U.S. person and owns or anticipates owning more than 5% of our units, such person should consult their tax advisors. The application of the FIRPTA rules to a non-U.S. person who holds (or is deemed to hold) more than 5% of our units would result in such non-U.S. person being liable for FIRPTA tax if such non-U.S. person disposes of our units at a time when we are a USRPHC or have at any time been a USRPHC within the shorter of such non-U.S. person's holding period or five years preceding the disposition.

If either our partnership or Brookfield Infrastructure were to be treated as a corporation for U.S. federal income tax purposes, the value of our units may be adversely affected.

The value of our units to unitholders will depend in part on our partnership and the Holding LP being treated as partnerships for U.S. federal income tax purposes. However, in order for our partnership to be considered 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, or the U.S. Internal Revenue Code, and the 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 Managing General Partner and the Infrastructure General Partner intend to manage our affairs so that our partnership would 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. (See, for example, the discussion of certain potential implications of President Obama's fiscal year 2012 budget proposal, under Item 10.E "Taxation—Certain Material U.S. Federal Income Tax Considerations—Partnership Status of our partnership and the Holding LP" below). If our partnership were treated as a corporation for U.S. federal income tax purposes, (i) the deemed conversion to corporate status would generally result in recognition of gain (but not loss) to U.S. Holders (as such term is defined in Item 10.E

"Taxation—Certain Material U.S. Federal Income Tax Considerations"); (ii) our partnership would likely be subject to U.S. corporate income tax and branch profits tax with respect to income, if any, that is effectively connected to a U.S. trade or business; (iii) distributions to our U.S. Holders would be taxable as dividends to the extent of our partnership's earnings and profits; (iv) dividends, interest, and certain other passive income our partnership receives from U.S. entities would, in most instances, be subject to U.S. withholding tax at a rate of 30% (although certain non-U.S. Holders (as such term is defined in Item 10.E "Taxation—Certain Material U.S. Federal Income Tax Considerations") nevertheless may be entitled to certain treaty benefits in respect of their allocable share of such income), and U.S. Holders would not be allowed a tax credit with respect to any such tax withheld; (v) the "portfolio interest" exemption would not apply to interest income of our partnership derived from entities bearing certain relationships to our partnership (although certain non-U.S. Holders nevertheless may be entitled to certain treaty benefits in respect of their allocable share of such income); and (vi) our partnership could be classified as a "passive foreign investment company" (as defined in the U.S. Internal Revenue Code), and such classification would have adverse tax consequences to U.S. Holders with respect to distributions and gain recognized on the sale of our units. In addition to the foregoing consequences, if our partnership were treated as a corporation for U.S. federal income tax purposes, and, as of the time of conversion from partnership status to corporate status, the value of our partnership's U.S. assets equaled or exceeded 60% of the value of our partnership's total assets, some or all of the net income recognized by our partnership subsequent to such conversion would be subject to U.S. corporate income tax. Our Managing General Partner and Infrastructure General Partner do not expect that our partnership's U.S. assets will at any time equal or exceed such thresholds. If Brookfield Infrastructure were to be treated as a corporation for U.S. federal income tax purposes, consequences similar to those described above would apply.

Neither our partnership nor Brookfield Infrastructure has requested, nor do they plan to request, a ruling from the Internal Revenue Service, or the IRS, on their tax status for U.S. federal income tax purposes or as to any other matter affecting us.

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 and local taxing authorities do not accept our withholding methodology, and such excess withholding tax cost will be an expense borne by our partnership, and, therefore, all of our unitholders on a pro rata basis.

We may become subject to U.S. "backup" withholding tax at the applicable rate (currently 28%) or other U.S. withholding taxes (potentially as high as 30%) with respect to any U.S. or non-U.S. Holder who fails to timely provide our partnership (or the 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 applicable state and local taxing authorities. See "Certain Material U.S. Federal Income Tax Considerations—Administrative Matters—Backup and Other Administrative Withholding Issues". Accordingly, it is important that each of our unitholders timely provides our partnership (or the clearing agent or other intermediary) with an IRS Form W-9 or IRS Form W-8, as applicable. To the extent that any unitholder fails to timely provide the applicable forms (or such form is not properly completed), or should the IRS or other applicable state and local taxing authorities not accept our withholding methodology, our partnership may treat such U.S. "backup" withholding taxes or other U.S. withholding taxes as an expense, which will be borne by all 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 entities may face certain adverse U.S. tax consequences from owning our units.

Our Managing General Partner and the Infrastructure General Partner intend 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 would constitute "unrelated

business taxable income" to the extent allocated to a tax-exempt entity). Our partnership and the Holding LP are not prohibited from incurring indebtedness, and at times either or both may do so. If any such indebtedness were used to acquire property by our partnership or by the Holding LP, such property generally would constitute "debt-financed property," and any income or gain realized on such debt-financed property (including a portion of any income or gain realized up to 12 months after all such debt has been repaid) and allocated to a tax-exempt entity generally would constitute "unrelated business taxable income" to such tax-exempt entity. In addition, even if such indebtedness were not used either by our partnership or by the Holding LP to acquire property but were instead used to fund distributions to our unitholders, if a tax-exempt entity subject to taxation in the United States used such proceeds to make an investment outside our partnership, the IRS could assert that such investment constitutes debt-financed property to such unitholder with the consequences noted above. Our partnership and the Holding LP intend not to have directly had, after December 31, 2009, any outstanding indebtedness that was used to acquire property, and thus the Managing General Partner and the Infrastructure General Partner do not believe that our partnership or the Holding LP will generate UBTI due to "debt-financed property" in the future. (Holding Entities, which are not partnerships, which are directly or indirectly owned by our partnership and the Holding LP have incurred acquisition indebtedness and may continue to incur acquisition indebtedness in the future).

A non-U.S. tax-exempt entity generally could be subject to taxation in the United States on its U.S. source unrelated business taxable income and on certain trade or business income that is effectively connected with the conduct of any trade or business of our partnership or the Holding LP in the United States. Our Managing General Partner and the Infrastructure General Partner intend 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 the conduct of a U.S. trade or business, but do expect our partnership and the Holding LP to realize some U.S. source investment income, which, if debt-financed, would constitute unrelated business taxable income.

The potential for having income characterized as unrelated business taxable income could make our units an unsuitable investment for a tax-exempt entity. A tax-exempt entity should consult its own tax advisor to determine the U.S. federal income tax consequences with respect to an investment in our units.

There may be limitations on the deductibility of our partnership's interest expense.

For so long as our partnership is treated as a partnership for U.S. federal income tax purposes, each of our unitholders that is a U.S. person (or otherwise taxable in the United States) generally will be taxed on their share of our partnership's net taxable income. However, U.S. federal income tax law may limit the deductibility of such a unitholder's share of our partnership's interest expense. In addition, deductions for such a unitholder's share of our partnership's interest expense may be limited or disallowed for U.S. state and local tax purposes. Therefore, any such unitholders may be taxed on amounts in excess of such unitholder's share of the net income of our partnership. This could adversely impact the value of our units if our partnership was to incur (either directly or indirectly) a significant amount of indebtedness. See Item 10.E "Taxation—Certain Material U.S. Federal Income Tax Considerations—Consequences to U.S. Holders—Holding of 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 Managing General Partner believes that our partnership is not engaged in a U.S. trade or business for U.S. federal income tax purposes, and intends to use commercially reasonable efforts to structure its activities 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. Accordingly our partnership's non-U.S. Holders will generally not be subject to U.S. federal income tax on interest, dividends and

gains derived from non-U.S. sources. It is possible, however, that the IRS could disagree or that the U.S. federal tax laws and Treasury regulations could change and our partnership could be deemed to be engaged in a U.S. trade or business, which would have a material adverse effect on non-U.S. Holders. If, contrary to our Managing General Partner's expectations, our partnership is considered to be engaged in a U.S. trade or business or realizes gain from the sale or other disposition of a United States Real Property Interest, non-U.S. Holders would be required to file U.S. federal income tax returns and would be subject to U.S. federal income tax at the regular graduated rates, which our partnership may be required to withhold.

To meet U.S. federal income tax and other objectives, our partnership and the Holding LP will invest through foreign and domestic 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 Holding LP will invest through foreign and domestic 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 and credit realized in the first instance by our operating entities will not flow, for U.S. federal income tax purposes, directly to Holding LP, our partnership, or our unitholders, and any such items may be subject to a corporate income tax, in the United States and other jurisdictions, at the level of the Holding Entities. Any such additional taxes may adversely affect our ability to operate solely to maximize our cash flow.

Certain of our Holding Entities or operating entities may be, or may be acquired through, an entity classified as a "passive foreign investment company" for U.S. federal income tax purposes.

U.S. Holders face unique U.S. tax issues from indirectly owning interests in a "passive foreign investment company", or PFIC, that may result in adverse U.S. tax consequences to them. Certain of the existing entities are "passive foreign investment companies" based on the analysis of the existing operating entities and Holding Entities. Furthermore, we may in the future acquire certain investments or operating entities through one or more Holding Entities which may be treated as corporations for U.S. federal income tax purposes, and such future Holding Entities or other companies in which we acquire an interest may be or become treated as PFICs. Provided a "QEF election" (as discussed in the section "Certain Material U.S. Federal Income Tax Considerations—Consequences to U.S. Holders—Passive Foreign Investment Companies" below) is made and a QEF information return is filed annually by the U.S. Holder, the PFIC status is not expected to have a material adverse effect on such U.S. Holder. Our partnership and Holding LP intend to dispose of some existing PFICs by December 31, 2011. However, there can be no assurance that a current or future investment will not qualify as a PFIC. Recently enacted U.S. legislation requires each U.S. person who directly or indirectly owns an interest in a PFIC to file an annual report with the IRS and failure to file such report could result in the imposition of penalties on such U.S. person. You should consult your own tax advisors as to the potential effects that this legislation might have on your filing requirements.

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

If our unitholders sell their units and are taxable in the United States, they will recognize a gain or loss for U.S. federal income tax purposes equal to the difference between the amount realized and the adjusted tax basis in those units. Prior distributions to our unitholders in excess of the total net taxable income allocated to them, which decreased the tax basis in their units, will in effect become taxable income to them for U.S. federal income tax purposes if our units are sold at a price greater than their tax basis in those units, even if the price is less than the original cost. A portion of the amount realized, whether or not representing gain, may be ordinary income to our unitholders.

Our structure involves complex provisions of U.S. federal income tax law for which no clear precedent or authority may be available. Our structure also is 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. Our unitholders should be aware that the U.S. federal income tax rules, particularly those applicable to partnerships, are constantly under review (including currently) by the Congressional tax-writing committees and other persons involved in the legislative process, the IRS, the U.S. Treasury Department and the courts, frequently resulting in revised interpretations of established concepts, statutory changes, revisions to regulations and other modifications and interpretations, any of which could adversely affect the value of our units and be effective on a retroactive basis. For example, changes to the U.S. federal tax laws and interpretations thereof could adversely affect the U.S. federal income tax treatment of publicly traded partnerships, including changes that make it more difficult or impossible for our partnership (and Brookfield Infrastructure) to meet the "qualifying income" exception to be treated as a partnership for U.S. federal income tax purposes that is not taxable as a corporation and changes that reduce the net amount of distributions available to our unitholders. (See, for example, the discussion of certain potential implications of President Obama's fiscal year 2012 budget proposal under Item 10.E "Taxation—Certain Material U.S. Federal Income Tax Considerations—Partnership Status of our partnership and the Holding LP" below). Such changes could also affect or cause us to change the way we conduct our activities, affect the tax considerations of an investment in our partnership, change the character or treatment of portions of our partnership's income (including changes that recharacterize certain allocations as potentially non-deductible fees) and adversely affect an investment in our units.

Our partnership's organizational documents and agreements permit our Managing General Partner to modify our limited partnership agreement from time-to-time, without the consent of our unitholders, to address certain changes in U.S. federal income tax regulations, legislation or interpretation. In some circumstances, such revisions could have a material adverse impact on some or all of our unitholders.

The IRS may not agree with certain assumptions and conventions that we use in attempting to comply with applicable U.S. federal income tax laws or that we use to report income, gain, loss, deduction and credit to our unitholders.

Our partnership will apply certain assumptions and conventions in an attempt to comply with applicable rules and to report income, gain, deduction, loss and credit to our unitholders in a manner that reflects such unitholders' beneficial ownership of partnership items, taking into account variation in ownership interests during each taxable year because of trading activity. Because our partnership cannot match transferors and transferees of our units, our partnership will adopt depreciation, amortization and other tax accounting conventions that may not conform to all aspects of existing Treasury regulations. In order to maintain the fungibility of all of our units at all times, we seek to achieve the uniformity of U.S. tax treatment for all purchasers of our units which are acquired at the same time and price (irrespective of the identity of the particular seller of our units or the time when our units are issued by our partnership) through the application of certain accounting principles that we believe are reasonable for our partnership. A successful IRS challenge to any of the foregoing assumptions or conventions could adversely affect the amount of tax benefits available to our unitholders and could require that items of income, gain, deductions, loss or credit, including interest deductions, be adjusted, reallocated or disallowed in a manner that adversely affects our unitholders. It also could affect the timing of these tax benefits or the amount of gain on the sale of our units and could have a negative impact on the value of our units or result in audits of and adjustments to our unitholders' tax returns.

Our unitholders may be subject to state, local and non-U.S. taxes and return filing requirements as a result of holding our units.

Our unitholders may be subject to 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 either our partnership or Brookfield Infrastructure does business or owns 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 those requirements. It is the responsibility of each of our unitholders to file all U.S. federal, state, local and non-U.S. tax returns that may be required of such unitholder.

Our partnership may not be able to furnish to each of our unitholders specific tax information within 90 days after the close of each calendar year, in which case our unitholders who are U.S. taxpayers would want to anticipate the need to file annually a request for an extension of the due date of their income tax return.

We expect that we will be providing Schedule K-1s to our unitholders no later than 90 days after the end of our partnership's fiscal year. If for some reason we are unable to do so, our unitholders who are U.S. taxpayers would want to anticipate the need to file annually with the IRS (and certain states) a request for an extension past April 15 or the otherwise applicable due date of their income tax return for the taxable year. See Item 10.E "Taxation—Certain Material U.S. Federal Income Tax Considerations—Administrative Matters—Information Returns".

The sale or exchange of 50% or more of our units will result in the 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 termination of our partnership would, among other things, result in the closing of our taxable year for U.S. federal income tax purposes for all our unitholders and could result in possible acceleration of income to certain of our unitholders and certain other consequences that may adversely affect the value of our units. However, the Managing General Partner does not expect a termination, should it occur, to have a material impact on the computation of the future taxable income generated by our partnership for U.S. income tax purposes.

Tax proposals may deny the deductibility of losses arising from our unitholders' units in our partnership in computing their income for Canadian federal income tax purposes.

On October 31, 2003, the Department of Finance released for public comment tax proposals, or the REOP Proposals, regarding the deductibility of interest and other expenses for purposes of the Income Tax Act (Canada), or the Tax Act. Under the REOP Proposals, a taxpayer would be considered to have a loss from a source that is a business or property for a taxation year only if, in that year, it is reasonable to assume that the taxpayer will realize a cumulative profit (excluding capital gains or losses) from the business or property during the period that the business is carried on or that the property is held. In general, these proposals may deny the deduction of losses arising from our unitholders' units in our partnership in computing their income for Canadian federal income tax purposes in a particular taxation year, if, in the year the loss is claimed, it is not reasonable to expect that an overall cumulative profit would be earned from the investment in our partnership for the period in which our unitholders held and can reasonably be expected to hold the investment. Our Managing General Partner and the Infrastructure General Partner do not anticipate that the activities

of our partnership and the Holding LP will, in and of themselves, generate losses. However, investors may incur expenses in connection with an acquisition of units in our partnership that could result in a loss that would be affected by the REOP Proposals. The REOP Proposals have been the subject of a number of submissions to the Minister of Finance (Canada). As part of the 2005 federal budget, the Minister of Finance (Canada) announced that an alternative proposal to reflect the REOP Proposals would be released for comment at an early opportunity. No such alternative proposal has been released to date. There can be no assurance that such alternative proposal will not adversely affect our unitholders or that it may not differ significantly from the REOP Proposals described above and in Item 10.E "Taxation—Certain Material Canadian Federal Income Tax Considerations."

If the non-Canadian subsidiaries in which Brookfield Infrastructure directly invests earn income that is foreign accrual property income 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-Canadian subsidiaries in which Brookfield Infrastructure will directly invest are expected to be "controlled foreign affiliates", as defined in the Tax Act, of Brookfield Infrastructure. If any of such non-Canadian subsidiaries earns income that is "foreign accrual property income", or FAPI, as defined in the Tax Act, in a taxation year, Brookfield Infrastructure's proportionate share of such FAPI must be included in computing the income of Brookfield Infrastructure for Canadian federal income tax purposes for the fiscal period of Brookfield Infrastructure in which the taxation year of such controlled foreign affiliate that earned the FAPI ends, whether or not Brookfield Infrastructure actually receives a distribution of such income. Our partnership will include its share of such FAPI of Brookfield Infrastructure 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 even though they have not and may not receive an actual cash distribution of such amount.

Unitholders may be required to include imputed amounts in their income in accordance with existing section 94.1 of the Tax Act as proposed to be amended under tax proposals announced on March 4, 2010 and contained in draft tax proposals released on August 27, 2010, if, having regard to all the circumstances, it is reasonable to conclude that one of the main reasons for the unitholder acquiring or holding units of our partnership is to derive a benefit from portfolio investments in such a manner that taxes under the Tax Act on income, profits and gains for any year are significantly less than they would have been if such income, profits and gains had been earned directly the unitholder.

On March 4, 2010, the Minister of Finance (Canada) announced as part of the 2010 Canadian Federal Budget that the outstanding tax proposals regarding investments in "foreign investment entities" would be replaced with revised tax proposals under which the existing rules in section 94.1 of the Tax Act relating to investments in "offshore investment fund property" would remain in place subject to certain limited enhancements. On August 27, 2010, the Minister of Finance (Canada) released draft legislation to implement the revised tax proposals will be released for public consultation. Existing section 94.1 of the Tax Act contains rules relating to investments in non-resident entities that could in certain circumstances cause income to be imputed to unitholders, either directly or by way of allocation of such income imputed to our partnership or to Brookfield Infrastructure. These rules would apply if it is reasonable to conclude, having regard to all the circumstances, that one of the main reasons for the unitholder, our partnership or Brookfield Infrastructure acquiring or holding an investment in a non-resident entity is to derive a benefit from portfolio investments in such a manner that taxes under the Tax Act on income, profits and gains for any year are significantly less than they would have been if such income, profits and gains had been earned directly. In determining whether this is the case, existing section 94.1 of the Tax Act as proposed to be amended, provides that consideration must be given to, among other factors, the extent to which the income, profits and gains

for any fiscal period are distributed in that or the immediately following fiscal period. If, having regard to the particular circumstances, it is reasonable to conclude that one of the main reasons for the acquisition or holding of our units by the unitholder, of units of Brookfield Infrastructure by our partnership, or of interests in non-resident entities (other than a controlled foreign affiliate) by Brookfield Infrastructure, is as stated above, income will be imputed directly to the unitholder or to our partnership or Brookfield Infrastructure and allocated to the unitholder in accordance with the rules in existing section 94.1 of the Tax Act as proposed to be amended. There can be no assurance that the revised tax proposals will be enacted as proposed or at all. The rules in existing section 94.1 of the Tax Act as proposed to be amended are complex and unitholders should consult their own tax advisors regarding the application of these rules to them in their particular circumstances.

Unitholders who are not resident in Canada may be subject to Canadian federal income tax with respect to any Canadian source business income earned by our partnership or Brookfield Infrastructure if our partnership or Brookfield Infrastructure were considered to carry on business in Canada.

If our partnership or Brookfield Infrastructure were considered to carry on a business in Canada for purposes of the Tax Act, unitholders who are not resident in Canada or deemed to be resident in Canada for purposes of the Tax Act, or 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 harbor 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 Managing General Partner and the Infrastructure General Partner intend 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 Brookfield Infrastructure 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 Canada Revenue Agency, or 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 Brookfield Infrastructure 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 of the taxation years in which they were 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 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 Brookfield Infrastructure on dispositions of "taxable Canadian property".

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 Brookfield Infrastructure on the disposition of "taxable Canadian property" as defined in the Tax Act which includes, but is not limited to, property that is used or held in a business carried on in Canada, shares of corporations resident in Canada that are not listed on a designated stock exchange, and listed shares where the number of shares owned exceeds prescribed amounts) other than "treaty protected property" as defined in the Tax Act. 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 Managing

General Partner and the Infrastructure General Partner advise that our partnership and the Holding LP are not expected 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 Brookfield Infrastructure unless the disposition is an "excluded disposition" for the purposes 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 that is an "excluded disposition" 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 a tax treaty. 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) is property in respect of the disposition of which a certificate under subsection 116(2), (4) or (5.2) 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 Brookfield Infrastructure.

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, the units are taxable Canadian property, unless the units are treaty-protected property to such non-Canadian limited partner. In general, our units will be taxable Canadian property at the time of disposition or deemed disposition of more than 50% of the fair market value of our units was derived, directly or indirectly, from one or any combination of (i) real or immovable property situated in Canada, (ii) Canadian resource properties, (iii) timber resource properties, and (iv) options in respect of or interests or civil law rights in such property Since our partnership's assets will consist principally of units of Brookfield Infrastructure, our units would generally be taxable Canadian property if the units of Brookfield Infrastructure held by us were considered to be used or held by us in a business carried on in Canada or if applying the greater than 50% test to Brookfield Infrastructure, its units were taxable Canadian property at any time during the relevant 60-month period.. Similarly, under these proposed amendment, units of Brookfield Infrastructure will not be taxable Canadian property at any time unless, at any time during the 60-month period preceding that time, more than 50% of the fair market value of its units was derived, directly or indirectly, from property described in (i) to (iv). Legislation to implement these proposed amendments is contained in Bill C-9 which received second reading in the House of Commons on April 19, 2010. Units of our partnership will be treaty protected property if the gain on the disposition of the units is exempt from tax under the Tax Act under the terms of an applicable income tax treaty or convention. Our Managing General Partner advises that our units are not expected to be taxable Canadian property but no assurance can be given in this regard. See Item 10.E "Taxation—Certain Material Canadian Federal Income Tax Considerations—Taxation of Non-Canadian Limited Partners." 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 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" as defined in subsection 116(6) of the Tax Act 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 Brookfield Infrastructure), are obligated to comply with the procedures set out in section 116 of the Tax Act and obtain a certificate thereunder. In order to obtain such certificate, the non-Canadian limited partner is required to report certain particulars relating to the transaction to the CRA not later than 10 days after the disposition occurs. Our Managing General Partner advises that our units are not expected to be taxable Canadian property and our Managing General Partner and the Infrastructure General Partner advise that our partnership and the Holding LP are not expected 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 exempt from Canadian federal withholding tax) by residents of Canada to Brookfield Infrastructure 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 to them by a person resident or deemed to be resident in Canada, including dividends or interest. Dividends or interest (other than interest exempt from Canadian federal withholding tax) paid by a person resident or deemed to be resident in Canada to Brookfield Infrastructure 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 Brookfield Infrastructure, we expect the Holding Entities to look-through Brookfield Infrastructure and our partnership to the residency of the partners of our partnership (including partners who are residents of 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 Brookfield Infrastructure. However, there can be no assurance that the CRA would 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 Canadian-United States Tax Convention (1980), or the Canada-U.S. Tax Treaty, a Canadian resident payer may be required to look-through fiscally transparent partnerships such as our partnership and the Holding LP to the residency of limited partners of our partnership who are entitled to relief under that treaty and take into account reduced rates of Canadian federal withholding tax that such limited partners may be entitled to under that treaty.

While we expect 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 by the Holding Entities to Brookfield Infrastructure, 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 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 Brookfield Infrastructure 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. Investors should consult their own tax advisors concerning all aspects of Canadian federal withholding taxes.

Our units 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 under the Tax Act (which includes the Toronto Stock Exchange, or the TSX, and the NYSE), our units will be "qualified investments" under the Tax Act for a trust governed by a registered retirement saving plan, deferred profit sharing plan, registered retirement income fund, registered education saving plan, registered disability saving plan, and a tax-free savings account. 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 registered plans and certain other taxpayers and with respect to the acquisition or holding of prohibited investments by a tax-free savings account.

Our units will not be a "prohibited investment" (within the meaning of the Tax Act) for a tax-free savings account, provided that the holder of such account deals at arm's length with our partnership for purposes of the Tax Act and does not have a "significant interest" (within the meaning of the Tax Act) in our partnership or in a corporation, partnership or trust with which our partnership does not deal at arm's length for purposes of the Tax Act.

The Canadian federal income tax consequences to our unitholders could be materially different in certain respects from those described in this annual report on Form 20-F if our partnership or Brookfield Infrastructure is a "specified investment flow-through" partnership.

Under the rules in the Tax Act, or the SIFT Rules, that apply to "specified Investment flow-through" partnership, or SIFT Partnership, certain income and gains earned by a SIFT Partnership, will be subject to income tax 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. 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 SIFT Rules (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 an "excluded subsidiary entity" as defined in the SIFT Rules), 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 with such entity, an aggregate fair market value that is greater than 50% of the equity value of the SIFT Partnership. The tax rate applied to the above mentioned sources of income and gains is set at a rate equal to the "net federal corporate tax rate", plus an amount on account of provincial tax.

Under the SIFT Rules, our partnership and the Holding LP could each be a SIFT Partnership if it is a "Canadian resident partnership". However, Brookfield Infrastructure would not be a SIFT Partnership if our partnership is a SIFT Partnership regardless of whether Brookfield Infrastructure is a Canadian resident partnership. 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 Managing General Partner

and the Infrastructure General Partner are located and exercise central management and control of the respective partnerships. Our Managing General Partner and the Infrastructure General Partner advise that they will each 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 and the Holding LP at any relevant time. However, no assurance can be given in this regard. If our partnership or Brookfield Infrastructure are SIFT Partnerships under the SIFT Rules, the Canadian 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, even if the SIFT Rules do not apply to our partnership or to Brookfield Infrastructure at any relevant time, 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.

Brookfield Infrastructure owns and operates high quality, long-life assets that generate stable cash flows, require relatively minimal maintenance capital expenditures and, by virtue of barriers to entry or other characteristics, tend to appreciate in value over time. Our current operations consist of utility businesses, transport and energy businesses and freehold timberlands in North and South America, Australasia and Europe.

Our vision is to be a leading owner and operator of high quality infrastructure assets that produce an attractive risk-adjusted total return for our unitholders. To accomplish this objective, we seek to leverage Brookfield's best-in-class operating platforms to acquire targeted assets and actively manage them to extract additional value following our initial investment. Brookfield has a strong track record of executing such transactions and actively managing underlying assets to improve performance.

Our objective is to earn a total return of 12% to 15% per year on the infrastructure assets that we operate, measured over the long-term. This return will be generated from the in-place cash flow of our current operations plus growth. We endeavor to manage our operations to generate increasing FFO per unit over time. If we are successful in doing so, we will be able to increase distributions to unitholders. Additionally, the increase in our FFO per unit should result in capital appreciation. Thus, for our business as a whole, our key performance measure is AFFO yield, defined as FFO less maintenance capital expenditures (adjusted funds from operations or AFFO) divided by invested capital, which is a measure of the sustainable return on capital that we have deployed. We also measure the growth of FFO per unit, which we believe is a proxy for our ability to increase distributions. In addition, we have performance measures that track the key value drivers for each of our operating platforms. See Item 5 "Operating and Financial Review and Prospects" for more detail.

Our objective is to pay a distribution that is sustainable on a long-term basis while retaining within our operations sufficient liquidity for recurring growth capital expenditures and general purposes. We currently believe that a payout of 60% to 70% of our FFO is appropriate. In light of the per unit FFO growth that we foresee in our operations, we are targeting 3% to 7% annual distribution growth. Our quarterly distribution was increased by 13% to $0.31 per unit in February 2011 following a 4% increase in February 2010.

Brookfield has an approximate 30% interest in Brookfield Infrastructure. Our partnership, the Holding LP and the Holding Entities have each appointed Brookfield as their Manager to provide certain management, administrative and advisory services, for a fee, under the Master Services Agreement.

Our partnership, Brookfield Infrastructure Partners L.P., is a Bermuda exempted limited partnership that was established on May 21, 2007 under the provisions of the Exempted Partnership Act, 1992 of Bermuda and the Limited Partnership Act, 1883 of Bermuda. Our registered office is Canon's Court, 22 Victoria Street, Hamilton HM 12, Bermuda. Our head office is 7 Reid Street, 4^th Floor, Hamilton HM 11, Bermuda and our telephone number at that address is +1 441 296-4480. Our partnership was spun off from Brookfield on January 31, 2008. The Holding LP was established by Brookfield to own and operate certain infrastructure assets on a global basis.

Prior to the spin-off, Brookfield acquired the following interests in our utilities and timber operations: (i) a 100% interest in our North American electricity transmission operations, in 1982; (ii) a 50% interest in our Canadian freehold timberlands, in May 2005; (iii) a 28% interest in our South American electricity transmission operations, in June 2006; (iv) 7% - 18% interests in Transmissoras Brasileiras de Energia, or TBE, a group of five related transmission investments in Brazil, in 2006; and (v) a 100% interest in our U.S. freehold timberlands, in April 2007. In conjunction with the spin-off, Brookfield contributed the following interests in our utilities and timber operations to us: (i) an 11% interest in our South American electricity transmission operations; (ii) a 100% interest in our North American electricity transmission operations; (iii) 7% - 18% interests in TBE; (iv) a 38% interest in our Canadian freehold timberlands; and (v) a 30% interest in our U.S. freehold timberlands.

Our South American electricity transmission operations in Chile were acquired by Brookfield on June 30, 2006 from Hydro Quebec International Inc. and International Finance Corporation by a consortium of buyers led by Brookfield. As part of the stock purchase agreement between the parties, the buyers agreed to pay a purchase price adjustment of $160 million that was determined on April 4, 2008 following the final resolution of the 2006 transmission rate proceeding. In conjunction with our disproportionate funding of this purchase price adjustment, our ownership in our South American electricity transmission operations in Chile increased to approximately 18% from approximately 11% at the time of the spin-off.

On November 4, 2008, we invested $103 million directly and indirectly (through the Brookfield Global Timber Fund) into our U.S. freehold timberlands to maintain our interest at the 30% level. The proceeds were used to partially fund the add-on acquisition of a 67,661 acre tree farm in Washington State for $163 million and repay our U.S. freehold timberlands' outstanding bridge loan whose principal amount was approximately $250 million.

On December 5, 2008, we completed the acquisition of two social infrastructure PPPs from an affiliate of Brookfield, the Peterborough Hospital in the United Kingdom and the Long Bay Forensic and Prison Hospitals in Australia for a total investment of approximately $12 million. On February 3, 2009, we completed the acquisition of an additional PPP project from an affiliate of Brookfield, the Royal Melbourne Showgrounds in Australia for an investment of approximately $3 million. Subsequent to year end, we have entered into agreements to sell our interests in the Long Bay Forensic and Prison Hospitals and Royal Melbourne Showgrounds in Australia for $15 million.

In January 2009, Brookfield and its partner Isolux, through their joint venture company, Wind Energy Texas Transmission, or WETT, were awarded the right to build $500 million of transmissions lines in Texas to facilitate the delivery of wind power to population centers as part of the Texas Competitive Renewable Energy Zones, or CREZ, program. We anticipate commercial operation of the Texas Electricity Transmission Project in the beginning of 2013, at which time WETT will be a licensed transmission utility in the state. In the third quarter of 2009, Brookfield contributed its interest in WETT to a Brookfield sponsored infrastructure partnership in which we own an interest. Upon finalization of the route selection, we believe this investment opportunity could increase to approximately $700 million and our ownership will ultimately be approximately 11% of the Texas Electricity Transmission Project.

On June 30, 2009, we completed the sale of our minority interest in TBE for after-tax proceeds of $275 million, including proceeds from foreign exchange currency hedges. The sale resulted in the recognition of an approximately $68 million after-tax gain over book value. We used a portion of the proceeds to repay corporate borrowings in full, with the balance available to fund growth capital investments and acquisitions, as well as for general working capital purposes.

On November 20, 2009, we invested $941 million to acquire a 40% interest in Prime Infrastructure (formerly Babcock & Brown Infrastructure), or the BBI Transaction, and direct interests in two assets from Prime. The first direct investment was in a UK port operation, which is one of the largest in the United Kingdom. The second investment is an economic interest in an Australian coal terminal operation, one of the largest coal export terminals in the world. Our interests in North American gas transmission operations, Australasian energy distribution operations, European energy distribution operations, Australian energy transmission operations, Australian railroad operations, and European port operations were held through Prime. In total, our investment in Prime was part of a comprehensive recapitalization in which Prime raised over $1.6 billion from our partnership, Brookfield and other investors to repay debt.

Our participation in the BBI Transaction was financed in part by a public offering of 40.7 million units at a price of C$15.55 per unit that closed in November, 2009. The net proceeds of the public offering, inclusive of the exercise of the underwriters' over-allotment option, were approximately C$601 million. We funded the balance of the $940 million investment in the BBI Transaction through the issuance of Redeemable Partnership Units and general partner units of the Holding LP to Brookfield at a price of approximately $13.71 per unit, representing the price of our units issued under the public offering net of underwriting commissions payable by our partnership, which allowed Brookfield to maintain its 41% interest in Brookfield Infrastructure.

On December 31, 2009, the Brookfield sponsored infrastructure partnership, through which a portion of our interest in our UK port operation is held, admitted a new limited partner resulting in the reduction of our ownership interest in this asset. In conjunction with the transaction, we received approximately $9 million, representing the original cost of the investment plus a notional interest charge.

On January 28, 2010, the Brookfield sponsored infrastructure partnership, through which a portion of our interests in our Australian coal terminal operations and our UK port operation is held, admitted a new limited partner resulting in the reduction in our ownership interest in these assets. In addition, we sold an approximate 1% interest in our Australian coal terminal operations to the new limited partner. In conjunction with the transaction, we received proceeds of approximately $22 million, representing the original cost of these investments plus a notional interest charge. As a result, our interests in our Australian coal terminal operations and our UK port operation were reduced to 46% and 51%, respectively.

On March 17, 2010, Brookfield Infrastructure invested approximately $11 million to acquire an interest in a 15 MW North American hydroelectric generating station located on the Kennebec River in Maine, U.S.

On September 20, 2010, Brookfield closed a $2.7 billion infrastructure fund. Brookfield will manage the fund and has committed 25% of the total capital commitments. We expect that its capital commitment would be primarily funded by Brookfield Infrastructure. We hold a portion of our interests in our Australian coal terminal operations, our UK port operations and our Texas electricity transmission project through this fund. From December 2009 until its final close in September 2010 the fund periodically admitted new limited partners which resulted in a reduction in our ownership interests in these assets. In addition, we sold an approximate 1% interest in our Australian coal terminal operations to a new limited partner. In conjunction with these transactions, we received approximately $74 million, representing the original cost of the investment plus a notional interest

charge. In addition, on June 11, 2010, Brookfield Infrastructure acquired Brookfield's remaining 16% interest in the UK port operations for approximately $27 million, representing the original cost of the investment plus a notional interest charge. Following these transactions, our ownership interest in our Australian coal terminal operations, our UK port operations and our Texas electricity transmission project were 41%, 59% and 11%, respectively.

On December 8, 2010, Brookfield Infrastructure completed the merger with Prime, resulting in Brookfield Infrastructure's ownership of Prime increasing from 40% to 100%. Pursuant to the merger, approximately 50.7 million limited partnership units were issued, including 0.9 million Redeemable Partnership Units to an affiliate of Brookfield. Following these transactions, there are approximately 157.4 million limited partnership units outstanding on a fully diluted basis and Brookfield has an approximate 30% interest in Brookfield Infrastructure on a fully exchanged basis and including its general partnership interest in the Holding LP.

In December 2010, Brookfield and Brookfield Infrastructure entered into a voting agreement, under which Brookfield agreed that any voting rights with respect to the Infrastructure General Partner, the Infrastructure GP LP and the Holding LP will be voted in accordance with the direction of our partnership with respect to the approval or rejection of the following matters relating to any such entity, as applicable: (i) any sale of all or substantially all of its assets, (ii) any merger, amalgamation, consolidation, business combination or other material corporate transaction, except in connection with any internal reorganization that does not result in a change of control, (iii) any plan or proposal for a complete or partial liquidation or dissolution, or any reorganization or any case, proceeding or action seeking relief under any existing laws or future laws relating to bankruptcy or insolvency, (iv) any amendment to the limited partnership agreement of the Infrastructure GP LP or the Holding LP, or (v) any commitment or agreement to do any of the foregoing. Pursuant to this voting agreement, Brookfield agreed that it will not exercise its right under the limited partnership agreements for certain entities (including the Infrastructure GP LP) to remove the general partner of such entities except with the prior consent of our partnership.

Brookfield Infrastructure's ownership of the European port operations is subject to a share equalization scheme. Dependent upon the business' financial performance in 2012 and 2013, Brookfield Infrastructure's ownership will range between 35% and 65%. We currently expect that our ownership will decrease to approximately 40%.

Our business is comprised of high quality, long-life assets that provide essential products and services for the global economy. We have a stable cash flow profile with over 77% of our EBITDA supported by regulated or contractual revenues. While each of our businesses has high barriers to entry and strong competitive positions, we generate cash flows under a number of different revenue frameworks. As a result, we group our businesses into operating platforms based on the similarities in their underlying economic drivers in order to assist our unitholders in evaluating our performance and assessing our value.

Operating Platform	Asset Type	Location

Utilities
	Electricity Transmission	North and South America
	Energy Distribution	Australasia and Europe
	Coal Terminal Operations	Australia
Transport and Energy
	Energy Transmission	Primarily North America
	Railroad	Australasia
	Ports	Europe and China
Timber
	Freehold Timberlands	North America

Our utilities platform is comprised of regulated businesses, which earn a return on their asset base, as well as businesses with long-term contracts designed to generate a return on capital over the life of the contract. Our transport and energy platform provides transportation, storage and handling services for energy, freight and bulk commodities for which we are paid an access fee. Profitability is based on the price and volume achieved for the provision of these services. Our timber platform is comprised of freehold timberlands that provide inputs for a number of essential products on a sustainable basis for the global economy, including structural lumber.

Our utilities platform is comprised of regulated businesses, which earn a return on their asset base, as well as businesses with long term contracts designed to generate a return on capital over the life of the contract. In this segment, we own and operate assets that earn a return on a regulated or notionally stipulated asset base, which we refer to as rate base. The rate base increases in accordance with capital that we invest to upgrade and expand our systems. Depending on the jurisdiction, our rate base may also increase by inflation and maintenance capital expenditures and decrease by regulatory depreciation. The return that we earn is typically determined by a regulator or contract for prescribed periods of time. Thereafter, it may be subject to customary reviews based upon established criteria. Due to the regulatory diversity we have within our utilities platform, we mitigate exposure to any single regulatory regime. In addition, due to the regulatory frameworks and economies of scale of our utilities businesses, we often have significant competitive advantages in competing for projects to expand our rate base. These competitive advantages often enable us to invest capital at attractive returns. Accordingly, we expect this segment to produce stable revenue and margins that should increase with the investment of additional capital and inflation. Virtually 100% of our utility platform's EBITDA is supported by regulated or contractual revenues.

Our objectives for our utilities platform are to invest capital in the expansion of our rate base and to provide safe and reliable service for our customers on a cost efficient basis. If we do so, we will be in a position to earn an appropriate return on our rate base. Our performance can be measured by the growth in our rate base, our return on rate base, as well as our AFFO yield.

Item 4.B "Business Overview—Ownership Interests" contains a table of our ownership interest in each of our operations.

Our Australian coal terminal operation comprises a port facility which exports metallurgical and thermal coal mined in the Bowen Basin region of Queensland, Australia, which is one of the lowest cost sources of coal in the world. Our Australian coal terminal operation is one of the world's largest export coal terminals, accounting for approximately 21% of global metallurgical seaborne coal exports and 8% of the total global seaborne coal exports. Our Australian coal terminal operations conduct business as Dalrymple Bay Coal Terminal, or DBCT. The following table sets forth the significant characteristics of our Australian coal terminal operations:


Cash Flow Profile:		Our Australian coal terminal operation generates revenues under long term take-or-pay contracts that are made up of two components: a capacity charge that is allocated to users based on the percentage of total capacity for which they contract and a fixed and variable handling charge associated with operating and maintaining the port. The capacity charge is paid by users irrespective of their use of our facility and is not subject to any force majeure provisions. The capacity charge is reviewed periodically and determined by the QCA. The current regulatory period is set for five and a half years ending June 30, 2016. The QCA utilizes a return on regulated asset base methodology to calculate an allowed weighted average cost of capital, or WACC, on a rate base that increases with inflation and capital expenditures and decreases by depreciation. Our current WACC is 9.86%. The handling charge (both fixed and variable) is structured to be a complete pass through of the costs charged for operating and maintaining our Australian coal terminal operations. Capacity is currently 100% contracted through 2014 with customers having an evergreen option to extend their capacity by a further five years.
Growth Opportunities:		Already one of the world's largest coal export terminals, our Australian coal terminal operations' capacity has recently been expanded to 85 mtpa to meet ongoing customer demand. Potential exists to expand operations to facilitate future expansions by mining companies in the Bowen Basin, which is one of the lowest cost sources of coal in the world. In July 2010, our Australian coal terminal operation was appointed as one of two preferred proponents for the development of new coal export terminal facilities at Dudgeon Point in the Port of Hay Point, which is located approximately four kilometers to the north of our facilities.

Our South American electricity transmission operations are the largest electricity transmission system in Chile, with approximately 8,200 km of transmission lines that serve 98% of the population of the country. Our South American electricity transmission operations' system includes 100% of Chile's 500 kV transmission lines, the highest voltage lines in the country, and approximately 45% and 94% of the 220 kV and 154 kV lines in Chile, respectively. Our South American electricity transmission operations conduct business as Transelec Chile S.A., or Transelec. The following table sets forth the significant characteristics of our South American electricity transmission operations:


Regulatory Environment:		Chile has a long tradition of transparent, stable regulatory frameworks. Regulated revenues are determined every four years based on a 10% annuity return on replacement cost of the existing transmission system plus annual payments that provide for recovery of operational, maintenance and administrative costs. Between rate reviews, both revenue components are adjusted by a multi-component inflation factor. Since the regulated assets earn a 10% annuity return on replacement cost, we effectively earn a real pre-tax 10% return on our regulated asset base. For the transmission sector, the 10% return is imbedded in Chilean law and is not subject to periodic regulatory review.
Customer Base:		Approximately 55% of our South American electricity transmission operations' revenues are derived from a number of long-term transmission contracts, primarily with power generators. These contracts have a pricing framework that is similar to the regulatory framework. The largest of these contracts expires in 2016. Following the expiration of these contracts, a majority of this contracted revenue will convert to the regulatory framework.
Cash Flow Profile:		Due to the regulatory framework and contracts, combined with the essential nature of the service, our South American electricity transmission operations have a very secure competitive position. Our South American electricity transmission operations generate stable revenue with no material volume risk, and in most instances, our revenue has automatic inflation escalators. Since the Chilean regulatory and contractual frameworks are based on replacement cost, our South American electricity transmission operations are not required to invest at its level of depreciation to prevent a decline in revenue. Since the system is in very good physical condition, maintenance capital expenditures are at relatively low levels. As a result of high profit margins combined with low maintenance capital expenditures, our South American electricity transmission operations generate strong cash flow.
Growth Opportunities:		Chile has economic generation that is many miles away from customers. Upgrades and expansions of the electricity transmission system will be required to connect this economic generation to load centers to satisfy increased electricity demand resulting from economic growth. As of December 31, 2010, the capital expenditure backlog (projects that have been awarded to our South American electricity transmission operations for which expenditures have not yet been made) was approximately $291 million. (Brookfield Infrastructure's portion is approximately $52 million.)

Our North American electricity transmission operations consist of approximately 550 km of 44 kV to 230 kV transmission lines in the province of Ontario which conduct business as Great Lakes Power Transmission L.P., as well as the Texas Electricity Transmission Project, which is described further in the

Growth Opportunities section of the table below. The following table sets forth the significant characteristics of our North American electricity transmission operations:


Strategic Position:		Our North American electricity transmission operations include an important component of Ontario's transmission system that connects generators in Northern Ontario to electricity demand in Southern Ontario.
Regulatory Environment:		Our Ontario electricity transmission operations' revenues are 100% regulated under a historical cost of service regime. Transmission revenues are based on periodic rate cases in which the Ontario Energy Board determines allowed revenue that provides for recovery of operations maintenance, and financing costs plus an after-tax return on equity.
Customer Base:		Our North American electricity transmission operations have a broad customer base. Furthermore, transmission revenues in Ontario are assessed and collected on a province-wide basis, mitigating volume and credit risk.
Cash Flow Profile:		Based on the 2011/2012 rate review, our Ontario electricity transmission operations were allowed to earn a 9.66% return on the equity, which is deemed to be 40% of our rate base. In Ontario, regulated rate base is equal to the historic cost of the system assets plus any capital expenditures less depreciation and other deductibles. Our operating revenues do not fluctuate with usage of our system but do fluctuate based on provincial electric loads which are measured by the Independent Electricity System Operator. Due to the regulatory framework combined with the essential nature of the service, our Ontario electricity transmission operations have a secure competitive position and generate stable cash flow.
Growth Opportunities:		Ontario has adopted a very aggressive Renewable Portfolio Standard through the passage of the Green Energy Act. A cornerstone of the Act requires the decommissioning of existing coal plants and replacement with renewable and clean sources of power. The majority of the new generation that will be developed is in remote locations far from the existing transmission grid. Upgrades and expansions of the electricity transmission system will be required to connect this generation to load centers to satisfy increased electricity demand resulting from economic growth. As an incumbent utility, our North American electricity transmission operations have an advantage in competing for these projects, and we have identified projects where, due to their geographic location and size, we believe that we have definitive and unique advantages for building and owning these new lines. In January 2009, Brookfield and its partner, Isolux, through a 50/50 joint venture were awarded the right to build $500 million of transmissions lines in Texas to facilitate the delivery of wind power to population centers as part of the CREZ program. We anticipate commercial operation of the project in the beginning of 2013. Upon finalization of the route selection, we believe this investment opportunity could increase to approximately $700 million and our ownership is approximately 11% of this project. The project conducts business as WETT.

Our Australasian energy distribution operations include New Zealand's second largest provider of regulated electricity and gas distribution services, with more than 420,000 connections across a service area of 39,000 km² on the North Island of New Zealand. Our Australasian energy distribution operations conduct business as Powerco Limited, or Powerco. The following table sets forth the significant characteristics of our Australasian energy distribution operations:


Strategic Position:		Our Australasian energy distribution operations own and operate New Zealand's second largest electricity and gas distribution company with connections to more than 420,000 users, and account for approximately 46% of the gas and approximately 16% of the electricity connections throughout New Zealand.
Regulatory Environment:		Powerco's electricity and gas distribution businesses are subject to economic regulation administered by the New Zealand Commerce Commission, or the NZCC. Powerco's electricity distribution business is subject to a default price path, or DPP, set by the NZCC, which determines the maximum annual increase in prices that can be applied in accordance with an escalation mechanism equal to inflation less a factor determined by the NZCC. Powerco has the option of applying for a customized price path, or CPP, which the NZCC will assess against published criteria. Powerco's gas distribution business is subject to an Authorization issued by the NZCC which provides for price and quality thresholds. When the Authorization expires on July 1, 2012, Powerco's gas distribution business will become subject to the DPP/CPP regime.
Customer Base:		Electricity and gas users are largely residential, generally served by retail energy companies, which are customers of our Australasian energy distribution operation. A significant portion of the residential energy companies in New Zealand are state owned.
Cash Flow Profile:		Revenue is mainly based on regulated tariffs, with a significant portion being from state owned enterprises. Electricity, which represents 80% of revenue, has grown at a 4.1% compound annual growth rate over the past five years.
Growth Opportunities:		Opportunities for growth are driven by increased energy demand and consumption levels, new connections as a result of new housing developments and regional economic and population growth.

Our European energy distribution operations is the second largest independent "last mile" natural gas and electricity connections provider in the United Kingdom, comprised of approximately 435,000 natural gas and electricity connections. Our European energy distribution operations conduct business as GTC. The following table sets forth the significant characteristics of our European energy distribution operations:


Regulatory Environment:		Our European energy distribution operations compete with other connection providers in the United Kingdom to secure contracts to construct, own and operate new natural gas and electricity connections. Then, once connections are established, our European energy distribution operations charge energy retailers a regulated tariff as described below.
Customer Base:		Our European energy distribution operations have a diverse customer base, throughout England, Scotland and Wales, that underpins its cash flow. Customers of our "last mile" electricity and gas connections business consist primarily of the big six U.K. energy retailers who serve residential and business users.
Cash Flow Profile:		In the United Kingdom, independent "last mile" connections businesses charge rates that are established based upon the tariff of the distribution utility, or DNOs, with which the independent connection provider is interconnected. The connection rate is typically adjusted annually and provides inflation protection by being linked to the regulated tariffs of the DNOs. During the first 20 years after the establishment of a connection, the gas connection rate is subject to a cap and floor that escalates by inflation less a factor determined by the U.K. regulator. Due to the average age of its asset base, our European energy distribution operations require minimal maintenance capital expenditures.
Growth Opportunities:		New connections in gas and electricity as the electricity market continues to open for independent connections providers and the housing market recovers, as well as opportunities for the construction and ownership of water and dark fiber connections and other sustainable energy solutions.

Our transport and energy platform is comprised of open access systems that provide transportation, storage and handling of energy, freight and bulk commodities. This operating platform is comprised of businesses with price ceilings as a result of regulation, such as our energy transmission and rail operations, as well as unregulated businesses, such as our ports. Transport and energy businesses typically have high barriers to entry and in many instances have very few substitutes in their local markets. While these businesses have greater sensitivity to market prices and volume than our utilities platform, revenues are generally stable and, in many cases, are supported by long-term contracts or customer relationships. Our transport and energy platform is expected to benefit from increases in demand for commodities as well as increases in the global movement of goods. Furthermore, the diversification within our transport and energy platform mitigates the impact of fluctuations in demand from any particular sector, commodity or customer. Approximately 70% of our transport and energy platform's EBITDA is supported by long-term contractual revenues.

Our objectives for our transport and energy platform are to provide safe and reliable service to our customers and to satisfy their growth requirements by increasing the utilization of our assets and expanding our capacity in a capital efficient manner. If we do so, we will be able to charge an appropriate price for our services, and we will be able to earn an attractive return on the capital that we have deployed as well as the capital that we will invest to increase the capacity of our operations. Our performance can be measured by our revenue growth, EBITDA margin as well as our AFFO yield.

Item 4.B "Business Overview—Ownership Interests" contains a table of our ownership interest in each of our operations.

Our North American gas transmission operations are comprised of the Natural Gas Pipeline Company of America, or NGPL, one of the largest natural gas transmission pipeline and storage systems in the United States. Our North American gas transmission operations' transportation system extends over 15,500 km, delivers approximately 2.2 trillion cubic feet of natural gas per year and also has seven major storage facilities with a combined working gas capacity of 275 billion cubic feet. The following table sets forth the significant characteristics of our North American gas transmission operations:


Strategic Position:		Our North American gas transmission operations is the largest provider of gas transmission and storage services to the Chicago and Northern Indiana market and has significant interconnectivity with local distribution companies, industrial users and gas fired power plants. The system is also well connected to other pipelines accessing additional downstream markets, which increase demand for our services. Our North American gas transmission operation provides transportation and storage to approximately 60% of the Chicago and Northern Indiana markets, and its storage facilities represent approximately 7% of total U.S. natural gas storage capacity.
		The large geographical footprint of our North American gas transmission operations' pipeline system traverses several of the prolific natural gas supply basins in the United States. and also provides access to high growth basins including the Rockies, East Texas, Eagleford, Granite Wash, and Haynesville as well as liquefied natural gas supply from the Gulf Coast.


Regulatory Environment:		Our North American gas transmission operation regulated by the Federal Energy Regulatory Commission, or FERC, under the Natural Gas Act. FERC provides a regulated framework for shippers and transmission pipeline owners to reach commercial agreement without direct intervention under a maximum rate regime, and there is no periodic rate case obligation. On November 19, 2009, FERC notified our North American gas transmission operations that it has commenced a proceeding pursuant to section 5 of the Natural Gas Act to review rates and determine whether they were just and reasonable. Our North American gas transmission operations negotiated a settlement with all interveners and FERC. On July 30, 2010, FERC determined that the settlement was fair and reasonable and in the public interest, and approved the settlement under its regulations.
Customer Base:		Our North American gas transmission operations have a diverse group of customers composed primarily of investment grade local distribution companies, producers, marketers, and industrial users. Its top ten customers account for over 60% of transportation and storage revenues.
Cash Flow Profile:		A majority of our revenues are generated under contracts with a demand charge and variable charge structure. The demand charge does not fluctuate with usage and is designed to cover fixed costs and our return of and return on our capital. The variable charge is designed to cover variable costs. Average contract terms are 2.8 years for transportation contracts and 3.5 years for storage contracts. Due to our strong market position in the Chicago and Northern Indiana market and our access to diverse sources of gas, we have a successful history of rolling over our contracts with customers.
Growth Opportunities:		Geographic proximity to large, emerging natural gas basins provides opportunity to continue extending the pipeline system to access new volumes.

Our Australian railroad operations are comprised of a rail access provider in Western Australia, or WA, with a long-term arrangement to lease track from the WA government. Our Australian railroad operations lease and operate approximately 5,100 km of track and related infrastructure in Southwestern Australia which serves as a crucial transport link in the region. Our Australian railroad operations conduct business as WestNet Rail (to be shortly renamed Brookfield Rail). The following table sets forth the significant characteristics of our Australian railroad operations:


Customer Base:		Our Australian railroad operations have access agreements with strong blue-chip customers, including a long-term agreement with Queensland Rail. Our Australian railroad operations' top nine customers contribute 90% of its revenue with contract expiration dates ranging from 2010 to 2026. The majority of customers are leading commodity companies.
Cash Flow Profile:		Our Australian railroad operations' revenue is derived from access charges paid by rail operators or directly by underlying customers. Stability of revenue is underpinned by rail transport being a small yet essential component of the overall cost of the commodities transported, the critical nature of the minerals, grain and interstate freight industries and long-term contracts with customers to ensure adequate access to the rail network, including some take-or-pay arrangements.
Growth Opportunities:		Our Australian railroad operations are well positioned to benefit from general increased economic activity in WA. It will also benefit from a number of mine expansions and new projects under development, which will require access to the system in order to transport these commodities to export markets. In total, we anticipate that these projects will increase the tonnage that is transported by our network by approximately 25 mtpa, or 50%. We expect the increase in tonnage related to these projects to begin in 2011 and continue through to 2014. While these mine expansion and new mine projects are well advanced, their ultimate timing is dependent on execution of the project by their sponsors and the availability of port capacity, both of which are beyond our control. In order to mitigate our capital at risk, we intend to structure our rail access agreements to include take-or-pay provisions and security for early termination to the extent possible.
		Our infrastructure is a critical component of the logistics chain in WA as, in many cases, it is the only economically viable means for the output from these projects to reach the export market. Significant capital was invested to establish the existing railway corridor, and we have made additional investments to enhance capacity of certain sections of our network. Should all of these projects proceed as expected, we anticipate investing a further approximately $600 million of capital over the next several years to upgrade and expand our network. Combined with our previous investments, we expect this will result in incremental EBITDA of $150 million to $200 million per year.

Our U.K. port operations is one of the largest port operators in the United Kingdom by volume and owns nearly 2,000 acres of land in proximity to the port. Our U.K. port is a "landlord" port with over 2,000 acres of land and operates as the statutory harbor authority, or SHA, out of Teesport and Hartlepool in the north of the United Kingdom. Our UK port operations also operate a number of other ports and logistics businesses elsewhere in the United Kingdom. Its status as an SHA enables it to charge conservancy tariffs for use of the Tees River and to operate as the port authority for Tees

River. Our U.K. port operations conduct business as Brookfield Ports (UK) Limited, or PD Ports. The following table sets forth the significant characteristics of our U.K. port operations:


Strategic Position:		Teesport is a large, deep-water port strategically located in a well-developed industrial area in Northern England. Our U.K. port operations' SHA status and good rail and road access provide barriers to entry.
Regulatory Environment:		Our U.K. port operations are unregulated. Our UK port operations status as the SHA for the Tees River provides us the statutory right to collect conservancy tariffs (toll-like dues) payable by ships using the Tees River in exchange for our obligations to maintain navigability of the waterway.
Customer Base:		Our U.K. port operations have a number of long-term contracts with strong, established counterparties, including large multinational corporations. The majority of its revenues are derived from customers with significant investment at or within close proximity to Teesport.
Cash Flow Profile:		Over 21% of our U.K. port operations' income is earned from conservancy tariffs related to the movement of cargo by established customers using the Tees River. Teesport's freehold land base of approximately 2,000 acres is strategically located in close proximity to its port locations and generates income from long-term property leases that account for 16% of our U.K. port operations income.
Growth Opportunities:		Due to increased fuel costs and congestion near London, many retailers have decided that it is more economical to deliver containers to ports such as Teesport from the ports of Southampton and Felixstowe rather than utilizing the road network. Due to its ability to access the Northern England market, our U.K. port operations are well positioned to benefit from this trend. In addition to recently completed distribution centers, a number of U.K. retailers are contemplating additional investment in distribution centers at or near the Tees River which will increase our revenue through additional conservancy volume, port services and potentially rental income, if such investments are made.

Our port operations are comprised of a portfolio of port concession businesses in key strategic locations throughout Europe and in China. Our European port operations is a diversified business that handles heavy dry bulk, specialty dry bulk, liquid bulk, general cargo and containers. Our European port operations make up one of the largest port operators in Europe and handle over 50 mtpa of cargo. Our European port operations conduct business as Euroports Holdings s.à.r.l., or Euroports. The following table sets forth the significant characteristics of our European port operations:


Regulatory Environment:		Our European port operations conduct business in an unregulated economic environment.
Customer Base:		Our European port operations mainly serve industrial customers in the immediate vicinity of the ports under varied contract terms. Key customers have been long-term customers of the respective port businesses continuously for between 10 and 30 years.
Cash Flow Profile:		Income is earned from diversified operations with over 50 different types of products handled at 22 terminals located throughout seven countries in Europe and China. Several of these locations face limited competition for key products handled, which provides additional stability to cash flow.
Growth Opportunities:		Growth opportunities exist in the form of volume growth from increasing demand for bulk and general commodities as well as cross-selling opportunities to develop additional commercial activities with existing customers.

Our European energy distribution operations are comprised of the sole gas distributor and retailer of liquid petroleum gas, or LPG, and natural gas on the Channel Islands and Isle of Man, or the Offshore Islands. Our European energy distribution operations conduct business as International Energy Group, or IEG Distribution. The following table sets forth the significant characteristics of our European energy distribution operations:


Strategic Position:		Our European energy distribution operations are the sole provider of gas distribution and retail services on the Offshore Islands.
Regulatory Environment:		Our European energy distribution operations' assets are not regulated, but are ultimately subject to government oversight.
Customer Base:		The natural gas and LPG distribution customer base on the Offshore Islands is comprised of a large number of residential and commercial end users.
Cash Flow Profile:		Our European energy distribution operations' broad customer base and position as sole provider of natural gas and LPG service ensure a consistent cash flow stream in a market that requires these services to meet space heating and hot water demands.
Growth Opportunities:		Increased energy demand combined with the ability to set prices competitively provides the opportunity for growth in revenues for the business.

Our Australian energy distribution operations are comprised of a natural gas distributor in Tasmania, which supplies gas to residential, commercial and industrial customers via its distribution networks and an associated gas retail business. With approximately 730 km of distribution pipeline, it delivers around 2 billion cubic feet of gas per year to approximately 8,900 connections across Tasmania. Our Australian energy distribution operations conduct business as Tas Gas Networks and Tas Gas

Retail. The following table sets forth the significant characteristics of our Australian energy transmission operations:


Strategic Position:		Our Australian energy distribution operations are the sole provider of gas distribution services in Tasmania. Sizeable capital expenditures of approximately A$200 million have been incurred to establish this network, which creates a significant barrier to new entrants due to the limited market opportunity for customers to support a competing business. Tas Gas Retail is one of two retailers trading across the natural gas distribution networks in Tasmania.
Regulatory Environment:		Our Australian energy distribution operation is not subject to economic regulation.
Customer Base:		Tas Gas Networks receives revenue from natural gas retailers who supply gas to approximately 8,900 residential, commercial and industrial customers connected to the network. Tas Gas Retail, as one of the natural gas retailers, receives revenue directly from its consumers.
Cash Flow Profile:		Our Australian energy distribution operations' cash flow stream is supported by the low cost of gas compared to electricity for residential customers while the investment made by industrial consumers to connect to the natural gas network creates a disincentive to switch.
Growth Opportunities:		The natural gas market in Tasmania is relatively new. The network currently fronts approximately 43,000 households with approximately 8,900 connections to date. Commercial and industrial growth is linked to the Tasmanian economy and alternate energy options, including cogeneration opportunities.

Our freehold timberlands comprise, on a proportionate basis, approximately 419,000 acres of high-quality, freehold timberlands located in the coastal region of British Columbia, Canada and the Pacific Northwest region of the United States. Our timberlands are predominantly comprised of premium Douglas-fir, whitewood and cedar species suitable for high value structural and appearance applications. In addition, our timberlands are situated near the Pacific coast which provides ready access to export markets. While North America and Japan have historically been the primary markets driving our timber operations' results, Asian export markets have become increasingly important. Our land holdings also include, approximately 12,300 acres of higher and better use, or HBU, lands, which may have greater value if used for real estate development or other purposes.

On a proportionate basis, our freehold timberlands have an estimated merchantable inventory of 29 million m³ of timber, which includes a deferred harvest volume of 3 million m³. This deferred harvest volume is in addition to harvest volumes that reflect annual timber growth as determined through our long-run sustainable yield, or LRSY. Our LRSY currently stands at 1.6 million m³ per year. As markets improve, we plan to ramp-up our production to monetize this deferred harvest volume over an approximate 10-year period. Our objective for our timber platform is to maximize the total return on the capital that we invest. Our performance can be measured by our harvest levels, EBITDA margin and AFFO yield.

Our U.S. freehold timberlands conduct business as Longview Timber Holdings, Corp., or Longview, and our Canadian freehold timberlands conduct business as Island Timberlands Limited

Partnership, or Island Timberlands. The following table sets forth the significant characteristics of our freehold timberlands:

Item 4.B "Business Overview—Ownership Interests" contains a table of our ownership interest in each of our operations.


Strategic Position:		Timber is a vital component of the global economy. Our U.S. and Canadian freehold timberlands are primarily comprised of softwood such as Douglas-fir and hemlock that are generally preferred over hardwood for construction lumber and plywood because of its strength and flexibility. Due to its product mix as well as coastal access, our U.S. timberlands have significant flexibility to optimize the products that it harvests against market opportunities to enhance profitability.
Regulatory Environment:		Our freehold timberlands operate in a regulated economic environment and are also certified under the Sustainable Forestry Initiative. This regulatory environment has been relatively stable over the past decade and allows access to all global markets.
Customer Base:		Our freehold timberlands have a broad base of domestic and international customers.
Cash Flow Profile:		Timber's unique characteristics provide the flexibility to match harvest levels to market conditions across market cycles. Thus, during periods of high prices, harvest levels are increased and, conversely, during weak pricing environments, timber harvests are curtailed.
Growth Opportunities:		We believe operating results will meaningfully improve following recovery in new home construction in the United States Although it is difficult to predict the timing and magnitude, we believe that we will achieve increased earnings due to improved pricing and increased harvest levels. As a result of a substantial surplus of merchantable inventory, we expect to increase harvest levels by approximately 90% (relative to 2009 levels) at our U.S. freehold timberlands and by approximately 65% (relative to 2009 levels) at our Canadian freehold timberlands and sustain this level for a 10-year period before returning to the long-run sustainable yield level.

In addition to our investments in utilities, transport and energy operations and freehold timberlands, Brookfield Infrastructure holds certain other investments which together comprise less than 2% of our invested capital.

To execute our vision, we will seek to leverage our relationship with Brookfield. In each of its core sectors, Brookfield's strategy is to develop best-in-class operating platforms in order to acquire targeted assets and actively manage them to achieve superior returns on a long-term basis. Brookfield's operations-oriented approach is comprised of the following attributes:

As we grow our asset base, we will target acquisitions in the following infrastructure sectors:

We will seek to leverage Brookfield's best-in-class operating platforms to invest in targeted assets and actively manage them to extract additional value following acquisition close. An integral part of our

acquisition strategy is to participate with institutional investors in Brookfield sponsored consortiums for single asset acquisitions and as a partner in or alongside Brookfield sponsored partnerships that target acquisitions that suit our profile. We will focus on consortiums and partnerships where Brookfield has sufficient influence or control to deploy our operations oriented approach. Brookfield has a strong track record of leading such transactions.

Brookfield has agreed that it will not sponsor arrangements that are suitable for us in the infrastructure sector unless we are given an opportunity to participate. See Item 7.B "Related Party Transactions—Relationship Agreement". Since Brookfield has large, well established operations in real estate and renewable power that are separate from us, Brookfield will not be obligated to provide us with any opportunities in these sectors. In addition, since Brookfield has granted an affiliate the right to act as the exclusive vehicle for Brookfield's timberland acquisitions in Eastern Canada and the Northeastern United States, we will not be entitled to participate in timberland acquisitions in those geographic regions. Brookfield also recently appointed an affiliate as its exclusive vehicle for the acquisition of contracted hydro and wind power generation facilities located in Canada.

Brookfield is a global asset management company focused on property, power and other infrastructure assets with over $100 billion of assets under management, 18,000 operating employees, including approximately 500 investment professionals, worldwide. Brookfield's strategy, which is part of our strategy as well, is to combine best-in-class operating platforms and best-in-class transaction execution capabilities to acquire and invest in targeted assets and actively manage them in order to achieve superior returns.

Our partnership does not employ any of the individuals who carry out the management and activities of our partnership.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Brookfield Infrastructure owns and operates high-quality, long-life assets that generate stable cash flows, require relatively minimal maintenance capital expenditures and, by virtue of barriers to entry and other characteristics, tend to appreciate in value over time. Our current operations consist of utility businesses, transport and energy businesses and timber assets in North and South America, Australasia, and Europe. Our vision is to be a leading owner and operator of high quality infrastructure assets that produce an attractive risk-adjusted total return for our unitholders. To accomplish this objective, we will seek to leverage Brookfield's best-in-class operating platforms to acquire targeted assets and actively manage them to extract additional value following our initial investment. An integral part of our strategy is to participate with institutional investors in Brookfield-sponsored partnerships that target acquisitions that suit our profile. We will focus on consortiums and partnerships in which Brookfield has sufficient influence or control to deploy an operations-oriented approach.

Our objective is to earn an annual total return of 12% to 15% on the infrastructure assets that we own, measured over the long-term. This return will be generated from the in-place cash flow of our operations plus growth. We endeavor to manage our operations to generate increasing funds from operations, or FFO, per unit. If we are successful in doing so, we will be able to increase distributions to our unitholders. Additionally, the increase in our FFO per unit should result in capital appreciation. Thus, for our business as a whole, our key performance measure is AFFO yield, defined as FFO less maintenance capital expenditures (adjusted funds from operations or AFFO) divided by Invested Capital, which measures the sustainable return on capital that we have deployed. We also measure the growth of FFO per unit, which we believe is a proxy for our ability to increase distributions. In addition, we have performance measures that track the key value drivers for each of our operating platforms. See "—Operating Platforms" for more detail.

These consolidated financial statements are prepared in accordance with International Financial Reporting Standards, or IFRS, as issued by the International Accounting Standards Board, or IASB. The consolidated financial statements include the accounts of Brookfield Infrastructure and the entities over which it has control. Brookfield Infrastructure accounts for investments over which it exercises significant influence, but does not control, using the equity method.

The results presented in this MD&A reflect the financial position and results of Brookfield Infrastructure's operations for the 12 month period ended December 31, 2010.

For each operating platform—utilities, transport and energy, and timber—this MD&A outlines Brookfield Infrastructure's proportionate share of results in order to demonstrate the impact of key value drivers of each of these operating platforms on our partnership's overall performance.

On December 8, 2010, we completed a merger with Prime whereby Prime security holders received 0.24 units per Prime security held and an A$0.20 per Prime security special distribution. Pursuant to the merger, Brookfield Infrastructure acquired control of Prime, issuing approximately 50.7 million units with a value on issuance of $1.1 billion in order to increase its ownership of Prime from 40% to 100%. The merger implicitly valued Prime at $1.8 billion. A non-cash revaluation gain of $405 million was recognized as the consideration paid was less than the net fair value of the assets acquired.

We are co-owners of a European-based port operator. Our current interest in the port is 60%; however, this ownership is subject to a share equalization scheme. Dependent upon the business financial performance in 2012 and 2013, this ownership will range between 35% and 65%. We currently expect that our ownership will decrease to approximately 40%.

Effective December 31, 2010, the partnership entered into voting arrangements with various affiliates of Brookfield Asset Management ("Brookfield"), Brookfield Infrastructure's ultimate parent company, whereby the partnership effectively gained control of Holding LP. The partnership entered into similar arrangements in respect of Brookfield's indirect holdings in its U.S. and Canadian freehold timberlands, Australian coal terminal operation and UK port operation, subject to certain limitations. This reorganization does not represent a business combination under IFRS 3, Business Combinations (IFRS 3R), as all combining businesses are ultimately controlled by the same parties both before and after the voting arrangements were completed. IFRS 3R does not include specific measurement guidance for transfers of businesses or subsidiaries between entities under common control. Accordingly, Brookfield Infrastructure has developed a policy to account for such transactions taking into consideration other guidance net out under the IFRS framework and pronouncements of other

standard-setting bodies. The consolidated and combined financial statements of Brookfield Infrastructure are presented to reflect continuing control as follows:

Our business is comprised of high-quality, long-life assets that provide essential products and services for the global economy. We have a stable cash flow profile with over 77% of our EBITDA supported by regulated or contractual revenues. While each of our businesses has high barriers to entry and strong competitive positions, we generate cash flows under a number of different revenue frameworks. As a result, we group our businesses into operating platforms based on the similarities in their underlying economic drivers in order to assist our unitholders in evaluating our performance and assessing our value.

Our utilities platform is comprised of regulated businesses, which earn a return on their asset base, as well as businesses with long-term contracts designed to generate a return on capital over the life of the contract. Our transport and energy platform provides transportation, storage and handling services for energy, freight and bulk commodities for which we are paid an access fee. Profitability is based on the volume of services that we provide and the price achieved for these services. Our timber platform is comprised of freehold timberlands that provide inputs for a number of essential products for the global economy on a sustainable basis, including structural lumber.

In this section, we review our performance and financial position for the 12 month period ended December 31, 2010. Further details on our operations and financial position are contained within the review of Operating Platforms.

To measure performance, we focus on net income as well as funds from operations, or FFO, and adjusted funds from operations, or AFFO. We define FFO as net income excluding the impact of depreciation, depletion and amortization, deferred taxes and other non-cash items and AFFO as FFO less maintenance capex. FFO is a measure of operating performance, and AFFO is a measure of the sustainable cash flow of our business. Since they are not calculated in accordance with, and do not have any standardized meanings prescribed by IFRS, FFO and AFFO are unlikely to be comparable to similar measures presented by other issuers. In addition, FFO and AFFO have limitations as analytical tools. See Item 5 "Operating and Financial Review and Prospects—Reconciliation of Non-IFRS Financial Measures" for a more fulsome discussion, including a reconciliation to the most directly comparable IFRS measures.

Our financial statements reflect a mix of consolidation and equity accounting. For more detail on the key drivers of our performance, refer to "—Operating Platforms".

The following table summarizes the financial results of Brookfield Infrastructure.

For the 12 month period ended December 31, 2010, we generated FFO of $197 million or FFO per unit of $1.79. On an invested capital base of $2,893 million, this represents an AFFO yield of 8%, driven by strong returns on capital in our utilities and transport and energy businesses offset by below average returns in our timber business. Our FFO per unit increased by 74% over the prior year, primarily due to a full year contribution from the assets acquired in the Prime recapitalization in

November of 2009. For the year, our distribution of $1.10 per unit implied a payout of 60% of our FFO, which is at the low end of our targeted range. In February 2011, we increased our annual distribution to $1.24 per unit.

For the 12 month period ended December 31, 2010, we recorded net income of $467 million, compared to $25 million in the same period of 2009. The increase from the prior period is primarily a result of a $433 million non-cash revaluation gain recognized upon the completion of the Merger Transaction.

Revenue less cost of revenues and general and administrative expenses for the period increased by $112 million, reflecting the full year contribution of our U.K. port operations and one month from the assets owned by Prime following acquisition of control through the Prime merger.

As of December 31, 2010, we had $13,109 million in assets and $3,380 million in partnership capital compared to $6,046 million in assets and $1,877 million in partnership capital at December 31, 2009. The increase in assets reflects the acquisition of Prime as a result of the Merger Transaction. The increase in partnership capital is primarily attributable to $1.1 billion of equity issued to complete the merger and the $433 million non-cash revaluation gain.

Corporate borrowings totaled $18 million at year end compared to a nil balance at the prior year end. Our consolidated balance sheet as of December 31, 2010 reflects $4,575 million of non-recourse borrowings compared to $1,985 million as of December 31, 2009, as a result of the acquisition of Prime. Our consolidated debt to capitalization ratio is 48%.

In 2010, our partnership increased the size of its senior secured revolving credit facility increased by $500 million to a total of $700 million all of which is available for investments and acquisitions, as well as general corporate purposes. As of December 31, 2010, we had $682 million of undrawn commitments under this facility.

As noted in Item 3.D "Risk Factors", general economic and business conditions that impact the debt or equity markets, such as the 2008 / 2009 global financial crisis, could impact the availability of

credit to, and cost of credit for, Brookfield Infrastructure. The amount of interest charged on Brookfield Infrastructure's facilities 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 Brookfield Infrastructure's business, financial condition and results of operations.

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.

In this section, we review the results of our principal operating platforms: utilities, transport and energy and timber.

Our utilities platform is comprised of regulated businesses which earn a return on their asset base, as well as businesses with long-term contracts designed to generate a return on capital over the life of the contract. In this segment, we own and operate assets that earn a return on a regulated or notionally stipulated asset base, which we refer to as the rate base. The rate base increases in accordance with capital that we invest to upgrade and expand our systems. Depending on the jurisdiction, our rate base may also increase by inflation and maintenance capital expenditures and decrease by regulatory depreciation. The return that we earn is typically determined by a regulator or contract for prescribed periods of time. Thereafter, it may be subject to customary reviews based upon established criteria. Due to the regulatory diversity we have within our utilities platform, we mitigate exposure to any single regulatory regime. In addition, due to the regulatory frameworks and economies of scale of our utilities businesses, we often have significant competitive advantages in competing for projects to expand our rate base. These competitive advantages often enable us to invest capital at attractive returns. Accordingly, we expect this segment to produce stable revenue and margins that should increase with investment of additional capital and inflation. Approximately 100% of our utility platform's EBITDA is supported by regulated or contractual revenues.

The following table presents the roll-forward of our rate base and selected key metrics:

The rate base for our utilities platform increased by 68% to $3,182 million during the year ended December 31, 2010 due primarily to the Merger Transaction whereby we acquired the remaining 60% of Prime. Our return on rate base for 2010 was 11% versus 14% in the prior year, primarily due to a change in our assets mix as a result of the Merger Transaction. For the year ended December 31, 2010, our utilities platform generated FFO of $144 million, compared to $61 million in the prior year, excluding a one-time gain of $68 million on the 2009 sale on TBE. After deducting maintenance capital

expenditures of $13 million, our weighted average AFFO yield was 15% on an invested capital base of $1,298 million. Our AFFO yield and return on rate base for the year were driven by strong performances by our Australian coal terminal and our electricity transmission businesses (see details below).

For the year ended December 31, 2010, our utilities platform generated EBITDA and FFO of $227 million and $144 million, respectively, compared to $89 million and $61 million in the comparable period of 2009, excluding the one-time gain on the sale of TBE in 2009. The increase in FFO is primarily attributable a full year of contribution from the assets acquired in the Prime recapitalization in November 2009 when we acquired a 40% interest in Prime, as well as the impact of the Merger Transaction.

The following table presents proportionate EBITDA and FFO for each operation in this platform:

Our Australian coal terminal and our South American electricity transmission operations were responsible for 65% of EBITDA and 68% of FFO in our utilities platform.

For the year, our Australian coal terminal reported EBITDA and FFO of $97 million and $59 million, respectively, in line with our expectations given the nature of the take-or-pay contracts with our mining customers.

From December 2010 through February 2011, Queensland, Australia was devastated by torrential rainfall that was 300% above normal levels. This has caused wide-spread flooding in the region, including at the coal mines in the Bowen Basin. As a result, coal production was substantially curtailed, and the rail network was operating under speed restrictions. On December 24, 2010, a Pacific National train derailed approximately 35 km west of our Australian coal terminal, which prevented coal from being received at the terminal until January 1, 2011. During December and January, our Australian coal terminal operated at approximately 55% of its 85 mtpa capacity. Despite the devastation caused by this severe weather, we can report that the terminal's financial performance was not impacted due to resilient take-or-pay contracts that do not have force majeure provisions.

Our South American electricity transmission operations' EBITDA and FFO for the period were $51 million and $39 million, respectively, versus $48 million and $36 million in 2009. The increases in EBITDA and FFO are mainly attributable to indexation and growth capital expenditures, which increased our recurring EBITDA by approximately $10 million, partially offset by a retroactive sub-transmission reassessment received in the prior year of approximately $5 million.

Non-cash expenses are primarily comprised of depreciation and amortization, non-cash inflation indexation on our Chilean peso denominated debt and unrealized mark-to-market losses on derivative contracts, which are a part of our net investment hedge program. Depreciation and amortization totaled $60 million for the year ended December 31, 2010, compared to $22 million in the prior year. The increase primarily related to our larger asset base.

Our utilities businesses have periodic reviews of their rates by regulators. However, our regulatory risk is reduced due to the number of jurisdictions in which we operate.

In December 2010, our Australian coal terminal's Draft Access Undertaking was approved by the Queensland Competition Authority, or QCA, effectively maintaining the current formula for calculating

our regulated WACC. The WACC that will apply to the new access undertaking is 9.86% compared with 8.9% for the prior period. This increased WACC translates into an incremental $70 million of revenue and EBITDA over the 5.5 year regulatory period commencing January 1, 2011.

Within our utility operations, we have numerous opportunities to upgrade and expand our rate base. While we are required to make certain capital expenditures to maintain safety and reliability, we will direct discretionary capital to those businesses that provide the highest risk-adjusted returns. In our utility platform, we expect to earn a return on the equity that we invest, which is consistent with the 12% to 15% return objective for our overall business.

Our capital project backlog is comprised of investments that will increase our rate base. It is defined as projects that have been awarded to us as well as projects that have been filed with the regulator with scheduled expenditures within the next two years, for which we have not invested the capital.

The following table presents the roll-forward of our capital project backlog for the year ended December 31, 2010:

We finished 2010 with a capital expenditure backlog of $310 million, an increase of $34 million compared with the prior year. In addition to the Merger Transaction, the increase is largely attributable to a transmission line that our South American electricity transmission operation is building for a mining company to facilitate an expansion of its copper mine. We are planning on closing the construction financing for our Texas electricity transmission project in the first half of 2011; following approval of our final certificate of convenience and necessity, we will begin construction on schedule in the latter half of the year. In 2011, we will endeavor to progress discussions with the customers of our Australian coal terminal operation regarding the Dudgeon Point expansion.

While our maturity profile is relatively modest in 2011 and 2012, we have been working hard to extend the duration of our debt portfolio to take advantage of the current low interest rate environment. In January 2011, we launched a $300 million issue in the Chilean capital markets to refinance a 2011 maturity. As a result of strong demand, our South American electricity transmission operation executed its lowest cost and longest term debt issue ever, with an average life of 18 years. In March 2011, our Australian coal terminal operation concluded agreements relating to a $600 million private placement in the United States. The proceeds of this private placement will be used to refinance debt that was due to mature in 2011 and for general working capital purposes. This refinancing consisted of $300 million of debt at nine years and $300 million at 12 years, which have been swapped to a fixed AUD rate of 7.6% and 7.7%, respectively. This result is an improvement over our underwriting model as we had assumed all-in rates of 8.5% for these refinancings. The expected timing for the closing and funding of this financing is mid-March 2011 for the 12 year and end of April 2011 for the nine year debt, subject to final lender due diligence.

Please refer to Item 3.D. "Risk Factors—Risks Relating to Us and Our Partnership—All of our infrastructure operations may require substantial capital expenditures in the future".

The following table presents the key metrics of our transport and energy platform:

Our transport and energy platform earned FFO of $91 million for the year ended December 31, 2010. After deducting maintenance capital expenditures of $33 million, we generated a weighted average AFFO yield of 9% on an invested capital base of $1,235 million, compared with 15% in the prior year. The comparison with the prior year is not meaningful as we only owned our assets for one month in 2009. However, our AFFO yield for the current year was impacted by lower FFO in our North American gas transmission operation (see detail below) due to the implementation of its reduction in rates and soft market conditions, and in our Australian railroad operations due to higher maintenance capital expenditures and to a weak fourth quarter that was impacted by lower grain harvest volumes due to drought conditions.

The following table presents our transport and energy platform's proportionate share of financial results:

Net income	$	75		$	4

For the year ended December 31, 2010, our transport and energy platform generated EBITDA and FFO of $169 million and $91 million, respectively, compared to $24 million and $13 million, respectively, in the same period of 2009, as a result of a full year of contribution from the assets acquired in the Prime recapitalization in November 2009 when we acquired 40% of Prime as well as the impact of the Merger Transaction.

The following table presents proportionate EBITDA and FFO for each business in this operating platform:

Our North American gas transmission operations, U.K. port operations and Australian railroad operations were responsible for 80% of EBITDA and 86% of FFO in our transport and energy platform.

Our North American gas transmission operations reported EBITDA and FFO of $62 million and $35 million, respectively, for 2010. This performance was below expectations due to the implementation of the rate settlement on July 30, 2010, combined with softening market conditions for certain products such as sales of retained natural gas, market sensitive transportation capacity and line pack services, offset by lower maintenance expenses.

Our U.K. ports operation reported EBITDA and FFO of $32 million and $17 million, respectively, for 2010, which was consistent with our expectations. We continue to benefit from volume growth in our Teesport container operations, which increased by 40% over last year. In addition, our results were favorably impacted by higher conservancy revenues. The volume growth in our container business was somewhat offset by lower margins due to inefficiencies arising from operating at full capacity. The container terminal expansion project, discussed below, will increase capacity and is expected to restore margins in this segment to historical levels.

Our Australian railroad operations reported EBITDA and FFO of $42 million and $26 million, respectively, for the year. These results were somewhat below expectations as a result of weak grain volume due to the drought in Western Australia. Our results were also impacted by higher maintenance costs.

In our transport and energy platform, we strive to increase the amount of goods that we can transport or handle in a capital efficient manner. Due to the economies of scale or strategic locations of our networks, we are often able to earn very attractive returns when we invest capital to expand our facilities to serve our customers' growth requirements.

The following table presents our proportionate share of growth capital expenditures that we anticipate investing during the next 24 months:

Driven by strong commodity prices, we are currently pursuing a number of significant projects to upgrade and expand the capacity of our Australian railroad operations to serve our customers' growth objectives. These projects, if completed, will serve a diverse group of new mines, mine expansions and industrial projects. Of these projects, the following six are notable as they are well advanced and significant in scale:

In total, we anticipate that these projects will increase the tonnage that is transported by our network by approximately 25 mtpa, or 50%. Contracts are either in place with each of these customers or currently under negotiation. We expect the increase in tonnage related to these projects to begin later this year and continue through to 2014. While each of these projects is well advanced, their ultimate timing is dependent on the execution of the project by their sponsors and the availability of port capacity, both of which are beyond our control. In order to mitigate our capital at risk, we intend to structure our current and proposed rail access agreements to include take-or-pay provisions and security for early termination to the extent possible.

Our infrastructure is a critical component of the logistics chain in Western Australia as, in many cases, it is the only economically viable means for the output from these projects to reach the export market. Significant capital was invested to establish the existing railway corridor, and we have made additional investments to enhance capacity of certain sections of our network. Should all of these projects proceed as expected, we anticipate investing a further approximately $600 million of capital over the next several years to upgrade and expand our network. Combined with our previous investments, this will result in incremental EBITDA of $150 million to $200 million per year.

As previously reported, Western Australia has been impacted by drought conditions which caused the 2010 grain harvest to be downgraded. While conditions have been more favorable than we initially anticipated, we are projecting a 40% reduction in grain volumes, which represents an approximately A$16 million reduction to revenues through the middle of 2011. During the fourth quarter of 2010, we aggressively reviewed our operating cost structure in order to implement savings, and we anticipate being able to mitigate a significant amount of this revenue shortfall.

Our U.K. port operations continue to perform well despite a weakened U.K. economy. Volumes in the chemical sector are low relative to historical levels but have begun to recover. At current volume levels, we have been able to increase pricing, which has improved our profitability. In addition, our Teesport container volumes increased by 40% versus last year as a result of two recently completed distribution centers by Tesco and ASDA. This growing segment is operating at capacity. We have

commenced the first phase of a £17 million expansion of our container terminal which will increase capacity at Teesport from 235,000 TEUs to 450,000 TEUs and enable us to restore the margin of this segment of our business to historic levels. Finally, we have finalized negotiations with Corus following the closure of its Teeside blast furnace. Under the terms of the settlement, Corus is paying us £2 million related to its minimum volume guarantees. Corus has executed a memorandum of understanding for the sale of its Teeside operation to Sahaviriya Steel Industries, or SSI, the largest Thai steel producer. Should the sale take place and the blast furnace reopen, results at our U.K. operations would be positively impacted. Based on Corus' historical performance, this could increase our EBITDA by £4 million to £6 million per year.

Our timber platform consists of high-quality, freehold timberlands located in the coastal region of British Columbia, Canada and the Pacific Northwest region of the United States. Our timberlands are predominantly comprised of premium Douglas-fir, whitewood and cedar species suitable for high value structural and appearance applications. In addition, our timberlands are uniquely situated near the Pacific coast, which provides ready access to export markets. While we benefit from strong export markets, North American housing starts remain the primary driver of our timber operations' results. Our land holdings also include a substantial amount of higher and better use, or HBU, lands, which may have greater value if used for real estate development or other purposes.

The following table presents our proportionate share of selected statistics of our timberlands:

Our timberlands have an estimated merchantable inventory of 29.1 million cubic meters of timber, which includes a deferred harvest volume of 3.0 million cubic meters. This deferred harvest volume is in addition to harvest volumes that reflect annual timber growth as determined through our long-run sustainable yield, or LRSY. As markets improve, we plan to increase our production to monetize this deferred harvest volume over an approximate 10-year period.

One of the key attributes of our timber platform is its operating flexibility, which allows us to optimize our harvest mix and harvest level as well as the markets into which we sell in order to maximize value. Based on anticipated market conditions, we plan our annual harvest to produce the products that offer the most attractive margins. Furthermore, we shift product sales between the domestic and export markets to maximize realized prices of our logs, net of transportation costs. When log prices are attractive, we increase harvest levels to monetize the value of our inventory. When log prices are weak, we grow inventory on the stump to enhance value through capital appreciation. Our objective for our timber platform is to maximize the total return on the capital that we invest. Our performance can be measured by our harvest level, EBITDA margin and AFFO yield.

The following table summarizes our harvest, sales and average realized price by species for our timber operations:

	For the Year Ended December 31, 2010								For the Year Ended December 31, 2009

UNAUDITED	Harvest (000's m³)		Sales (000's m³)		Revenue/m³		Revenue ($ millions)		Harvest (000's m³)		Sales (000's m³)		Revenue/m³		Revenue ($ millions)

From a macroeconomic perspective, U.S. housing starts increased 6% over the 2009 level to 588,000. This level remains at approximately 40% of long-term trend levels as a result of the continuing overhang from the inventory of foreclosed homes.

Our average realized price for Douglas-fir and whitewood increased by 12% and 19%, respectively, over the prior year. In 2010, conditions in the domestic market improved considerably compared to 2009 as local consumers were forced to compete with strong off-shore demand for logs. Inventory restocking by domestic sawmills in the second quarter also contributed to the year-over-year price improvements. Net prices in key off-shore markets, such as Japan, South Korea and China, improved dramatically year-over-year, with Douglas-fir prices in these markets increasing by 7%, 15% and 13%, respectively. Whitewood prices in South Korea and China increased by 33% and 24%, respectively, over the prior year.

In response to a stronger price environment, we increased harvest volumes of Douglas-fir and whitewood by 21% and 44%, respectively, compared with 2009. However, our harvest for the year was 77% of our LRSY due to a relatively low level of production of our high value Douglas-fir.

The following table presents our timber platform's proportionate share of financial results:

	For the Year Ended December 31,

MILLIONS, UNAUDITED	2010			2009
Revenue	$	106		$	77

For the year ended December 31, 2010, our timber operations generated FFO of $11 million, compared to negative $3 million in the prior year. This implies an AFFO yield of 2%. Our timber platform is not expected to earn a normalized AFFO yield until there is a sustained recovery in log prices that justifies increasing harvest levels of our high-margin Douglas-fir logs to our long-term harvest plan.

Our average realized log price for the year increased by almost 10% over the prior year to $79 per cubic meter, reflecting improved conditions in both domestic and export markets. Overall, sales volumes increased by 23% compared with the prior year. We continued our active participation in off-shore markets with export volumes representing 46% of shipments in 2010, compared to 42% in 2009. Harvest and delivery costs per unit were unchanged from 2009. As a result of these factors, EBITDA margin increased to 34% from 28% in the prior year.

Our revenue from HBU land and other sales was $4 million for the period compared to $1 million in 2009.

For the year ended December 31, 2010, fair value adjustments were $10 million compared to negative $66 million in the prior year. This reflects adjustments to appraised values of our timberlands and is the result of changes in the underlying valuation assumptions used by the appraisers, including discount rates, future timber prices, future harvest costs and future harvest schedule.

The rapid development of the Chinese market has been particularly encouraging for our timber business. Due to changes in building codes, the Chinese market is increasing its purchases of higher-grade Douglas-fir logs in order to produce structural lumber. In 2010, shipments of logs to China represented 36% of total export volume, up from 11% in 2009.

Over the mid-to-long term, we expect that our timber operations will be positively impacted by a number of fundamental factors affecting the markets that we serve:

The following table presents the components of Corporate and Other, on a proportionate basis, for the 12 months ended December 31, 2010 and 2009:

General and administrative costs were higher in 2010 compared to the prior year primarily as a result of the inclusion of our proportionate share of Prime's corporate, general and administrative expenses for a full year following the Prime recapitalization.

Pursuant to the Master Services Agreement, we pay a quarterly base management fee to Brookfield based on our market value. This fee increased over the prior year due to the $940 million equity offering completed in November of 2009, the $1.1 billion equity offering completed in December 2010 and the increased trading price of our units.

Following the Merger Transaction, a substantial amount of the corporate and administrative services that were formerly provided by Prime will be provided by Brookfield under the Master Services Agreement. As a result, a substantial amount of these costs have been absorbed by Brookfield. Prospectively, we anticipate that our corporate and administrative costs, excluding the base management fee, will be in the range of $8 million to $10 million per year.

Included in other income is non-recurring interest income of $3 million associated with the final close of the Brookfield-sponsored infrastructure fund. Also included in other income are realized gains of $1 million on the settlement of forward contracts to purchase pound sterling with respect to our equity investment in the Peterborough Hospital project.

Financing costs include dividends paid on our preferred shares, interest expense and standby fees on our committed credit facility, less ancillary interest earned on cash balances. These costs exclude non-cash amortization of financing costs of $4 million for the year ended December 31, 2010. Financing costs for the year were in-line with the comparable period in the prior year.

Other Income includes the results from our 30% interest in a U.S. hydro facility and our investments in three PPPs. On a proportionate basis, our other investments earned FFO of $2 million in 2010, which is comparable to 2009.

The interest in the U.S. hydro facility was acquired on March 17, 2010 for $8 million. Both units of this two unit hydro facility are being rebuilt, and we have invested an additional $1 million to fund our share of these repairs.

Our PPPs differ from our other infrastructure assets. PPPs have finite concessions of between 25 to 30 years, and cash generated from these projects must fully retire project debt over the term of the concession. Thus, FFO for our PPP operations includes IFRS net income plus depreciation less

debt amortization payments, which approximates the distributions to us from these operations. These projects are expected to generate stable cash flows from long-term contracts combined with long-term financing arrangements.

We have a commitment to fund our share of the additional required equity investment for the Peterborough Hospital project. During the year, we funded approximately $11 million.

Subsequent to year end, Brookfield Infrastructure entered into an agreement to sell its two Australian PPPs for $15 million.

The nature of our asset base and the quality of our associated cash flows enable us to maintain a stable and low cost capitalization. We attempt to maintain sufficient financial liquidity at all times so that we are able to participate in attractive opportunities as they arise, better withstand sudden adverse changes in economic circumstances and maintain a relatively high distribution of our FFO to unitholders. Our principal sources of liquidity are cash flows from our operations, undrawn credit facilities and access to public and private capital markets. We also structure the ownership of our assets to enhance our ability to monetize them to provide additional liquidity, if necessary.

Our $700 million committed revolving credit facility is available for investments and acquisitions, as well as general corporate purposes. Commitments under the facility will be available on a revolving basis until June 2013. All amounts outstanding at that time will be repayable in full. The facility is intended to be a bridge to equity financing rather than a permanent source of capital. At December 31, 2010, $18 million was drawn on this facility.

We finance our assets principally at the operating company level with debt which generally has long-term maturities, few restrictive covenants and no recourse to either Brookfield Infrastructure or our other operations. At the operating company level, we endeavor to maintain prudent levels of debt. We also strive to ladder our principal repayments over a number of years.

On a proportionate basis, scheduled principal repayments for our borrowings over the next five years as of December 31, 2010 are as follows:

Our debt has an average term of six years. On a proportionate consolidated basis, our net debt-to-capitalization ratio as of December 31, 2010 was 59%.

The following table summarizes our proportionate average debt balance allocated to each operating platform:

Our equity strategy is to issue equity in conjunction with future acquisitions. However, we may also issue an amount of equity opportunistically to enhance our liquidity to pursue future acquisitions. In December 2009, we filed shelf registrations to enable us to issue securities in both the U.S. and Canadian markets.

To the extent it makes economic sense to do so, our strategy is to hedge a portion of our equity investment and/or cash flows exposed to foreign currencies. The following key principles form the basis of our foreign currency hedging strategy:

The following table presents the hedged position of our equity investment in foreign currencies as of December 31, 2010:

	Net Investment Hedges

% of Equity Investment hedged		n/a		30%			44%			—		25%			29%

At December 31, 2010, we had hedges in place equal to approximately 30% of our equity investment in foreign currencies. We recorded losses of $53 million in comprehensive income relating to these contracts, which were more than offset by foreign currency translation gains of $112 million recorded during the year.

Our financing plan is to fund our recurring growth capital expenditures with cash flow generated by our operations, as well as debt financing that is sized to maintain our credit profile. To fund large scale development projects and acquisitions, we will evaluate a variety of capital sources, including proceeds from selling non-core assets, equity and debt financing. We will seek to raise additional equity if we believe that we can earn returns on these investments in excess of the cost of the incremental equity. During the year, we generated $105 million of cash available for re-investment in our business, and we invested $130 million in growth capital projects.

The following table highlights the cash flow generated during the year which was available for reinvestment in our business:

The following table presents the components of growth and maintenance capital expenditures:

		For the Year Ended December 31,

	Utilities	$	13	$	12
	Transport and energy		33		—

Based on our current operations, we expect that maintenance capital expenditures will be in the range of $90 million to $100 million in 2011.

As of December 31, 2010, our partnership owns limited partnership units that represent approximately 71% of the Holding LP's total outstanding units, and Brookfield owns Redeemable Partnership Units that represent approximately 28% of the Holding LP's total outstanding units. The Redeemable Partnership Units, at the request of the holder, require the Holding LP to redeem all or a portion of the holder's units for cash in an amount equal to the market value of our units multiplied by the number of units to be redeemed. This right is subject to our partnership's right of first refusal which entitles it, at its sole discretion, to elect to acquire all units so presented to the Holding LP in exchange for units on a one-for-one basis, subject to certain customary adjustments. As these Redeemable Partnership Units can be settled on a one-for-one basis at the sole discretion of our partnership with our units, Brookfield Infrastructure classifies these units as limited partnership units of our partnership. Based on the number of units outstanding as of December 31, 2010, Brookfield's aggregate limited partnership interest in our partnership would be approximately 29%, if Brookfield fully exercised its redemption right and our partnership fully exercised its right of first refusal.

Brookfield also owns general partnership units that represent approximately 1% of the Holding LP's total outstanding units. The general partner is entitled to incentive distribution rights which are based on the amount by which quarterly distributions on the limited partnership units exceed specified target levels. To the extent distributions on limited partnership units exceed $0.305 per quarter, the incentive distribution rights are entitled to 15% of incremental distributions above this threshold. To the extent that distributions on limited partnership units exceed $0.33 per quarter, the incentive distribution rights are entitled to 25% of incremental distributions above this threshold.

As of December 31, the total number of our limited partnership units outstanding was comprised as follows:

During 2010 and 2009, the number of our issued and outstanding limited partnership units changed as follows:

During 2010 and 2009, the number of our issued and outstanding general partnership units changed as follows:

On December 8, 2010, we completed the Merger Transaction whereby Prime security holders received 0.24 units and A$0.20 per Prime security held. As a result, we increased our ownership of Prime from 40% to 100%. We issued approximately 49.8 million units at $21.45 per unit and 0.9 million Redeemable Partnership Units at an average price of $18.31 per unit (or 50,735,149 units, including Redeemable Partnership Units, in the aggregate at an average price of $21.31 per unit) in connection with the Merger Transaction. Our partnership had 112,964,451 units outstanding at December 31, 2010, which are publicly traded on the NYSE and TSX. Our partnership owns 112,964,451 of the Holding LP's limited partnership units representing an economic interest of 71%. The Holding LP had 43,396,642 Redeemable Partnership Units outstanding at December 31, 2010, which are owned by Brookfield.

In June 2010, we implemented a distribution reinvestment plan, or the Plan, that allows eligible holders of our partnership to purchase additional units by reinvesting their cash distributions. Under the Plan, units are acquired at a price per unit calculated by reference to the volume weighted average of the trading price for our units on the NYSE for the five trading days immediately preceding the relevant distribution date. During the period, our partnership issued 44 units under the Plan.

In December 2010, we implemented a unit repurchase program. Repurchases were authorized for the period beginning on December 10, 2010 and ending on December 9, 2011. In the year ended December 31, 2010, no units were repurchased and cancelled under this program. See Item 16E. "Purchases of Equity Securities by the Issuer and Affiliated Purchaser" for more information.

Our business is impacted by changes in currency rates, interest rates and other financial exposures. As a general policy, we endeavor to maintain balanced positions where practical or economical to do so, although unmatched positions may be taken. Our principal financial risks are foreign currency and interest rate fluctuations.

We prefer to hedge financial risks with offsetting items, such as debt denominated in local currencies, that match the profile of the operations being financed. We also make selective use of financial instruments, known as derivatives, to hedge financial positions from time-to-time when natural

hedges are not available or when derivatives are more cost effective. The use of derivatives is governed by prescribed policies. We evaluate and monitor the credit risk of derivative financial instruments, and we seek to minimize credit risk through collateral and other mitigation techniques.

A number of our operations are conducted in currencies other than the U.S. dollar. Our policy is to hedge our foreign currency denominated book values and/or cash flows where economical to do so, using foreign currency denominated debt as well as financial contracts. It is not always possible, or economically feasible or desirable, to hedge certain exposures with the result that a portion of our cash flows and equity are exposed to foreign currency fluctuations. We may also enter into financial contracts to further hedge our equity investment recognizing that in some cases changes to the value of these contracts may be reflected in net income even though the offsetting impact on the value of our equity investment being hedged may not. We have economic currency exposure to the Chilean peso, pound sterling, Euros, Australian dollar, New Zealand dollar and Canadian dollar.

We believe that the value of the majority of our assets will vary in part with changes in long-term interest rates due to the nature of their revenue streams. Accordingly, we endeavor to finance these assets with long-term fixed rate borrowings. We intend to match fund floating rate assets with floating rate debt and will otherwise minimize the use of floating rate liabilities. Where financing cannot be obtained to match the interest rate exposure of the asset, derivative contracts may be entered into with credit worthy counterparties.

We are exposed to market risks in our underlying operations, principally resulting from changes in interest rates and currency exchange rates. In addition, we have indirect exposure to market risks through our investment in Prime which has exposure to market risks in its underlying operations, primarily resulting from changes in interest rates and currency exchange rates.

Interest rate risk exists principally due to our subsidiaries and associates indebtedness with variable rates. Our subsidiaries have long-term debt of $5,032 million (on a proportionate basis) as of December 31, 2010, of which approximately 46% has been issued as floating rate debt. Our subsidiaries have entered into interest rate swaps whereby the floating rate debt has been converted to fixed rate debt, effectively reducing floating rate debt to approximately 8%, 9%, 9%, 10%, 14%, and 16% as of December 31, 2010, 2011, 2012, 2013, 2014 and 2015, respectively. Brookfield Infrastructure has corporate indebtedness of $18 million as of December 31, 2010, of which 100% is floating rate debt.

Certain of our subsidiaries and associates are subject to inflation risk. Most significantly, our South American electricity transmission operations in Chile is subject to inflation risk as 74% of its debt portfolio is denominated in Unidad de Fomento, or UF, which is an inflation indexed Chilean peso monetary unit that is set daily, on the basis of the prior month's inflation rate. However, we believe this is offset by the nature of our revenues which, both contractually and in the regulatory framework, are in large part indexed to Chilean inflation.

Our principal foreign exchange risks involve changes in the value of the Australian dollar, pound sterling and Chilean peso versus the U.S. dollar, and to a lesser extent, changes in the Canadian dollar, Euro and New Zealand dollar versus the U.S. dollar. Our strategy with respect to hedging this risk is

primarily to hedge utilizing foreign currency derivative contracts as described above in the foreign currency hedging strategy section.

Within our South American electricity transmission operation and our Canadian businesses, we also utilize natural hedges. Although revenue from our South American electricity transmission operation in Chile are billed in Chilean pesos, they are a combination of Chilean peso and U.S. dollar amounts that are converted to Chilean peso prior to invoicing from an economic perspective. These revenues are calculated based upon a return on the replacement cost of the transmission system, which is comprised of components denominated in U.S. dollars as well as Chilean peso. Based on existing long-term contracts and the current regulatory framework, we estimate that our revenues are 69% Chilean peso and 31% U.S. dollar. Factoring in our Chilean peso debt financings and cross-currency interest rate swaps, we estimate that FFO from South American electricity transmission operations are 40% U.S. dollar and 60% Chilean peso.

Our Canadian dollar exposure is attributable to our North American electricity transmission operations and our Canadian freehold timberland. From a strategy stand point, we offset the long position in Canadian dollars from our North American electricity transmission operations with our Canadian freehold timberland with a short position in Canadian dollars. Our Canadian freehold timberland's output is sold into both international and local markets. We view the international timber market as a market that is denominated in U.S. dollars, whereas the local market is denominated in Canadian dollars. Our local timber sales offset roughly half of our operating and maintenance costs, which are largely Canadian dollar based. Our Canadian freehold timberland's project debt financing is U.S. dollar based. As a result, this operation has effectively a short position in Canadian dollars.

Our principal commodity risks are to the price of timber and natural gas, and to a lesser extent metals, primarily aluminum. All of our Canadian and U.S. timber operations' log sales are at short-term market prices. As there is no liquid forward contract to hedge our position, we are exposed to fluctuations in log prices.

Approximately 90% of revenues from our South American electricity transmission operation in Chile are adjusted on a semi-annual basis by a multi-factor inflation index that is designed to approximate changes in prices of the underlying components of the replacement cost of our transmission system. See Item 4.B "Business Overview". Due to the construction of the system, metals, such as aluminum, are a material percentage of replacement cost. Thus, changes in the price of these metals will impact our revenues.

Certain of our subsidiaries have indirect exposure to natural gas as increased demand for natural gas increases utilization of their networks. Furthermore, our North American gas transmission operations have direct natural gas exposure as it collects more natural gas from customers than it consumes and resells the balance; however, this exposure has been significantly reduced as a result of the FERC settlement agreed to in July 2010. See Item 4.B "Business Overview—Current Operations—Transport and Energy Operations—North American Gas Transmissions Operations, United States" for more information.

We do not currently use any strategies or instruments to manage the commodity risks in our operations.

In addition, pursuant to the Master Services Agreement, on a quarterly basis, our partnership pays a base management fee to the Manager equal to 0.3125% (1.25% annually) of the market value of our partnership. Based on the market value of our partnership as of December 31, 2010, this fee is estimated to be approximately $40 million per year.

We have entered into a number of related party transactions with Brookfield. See Item 7.B—"Related Party Transactions."

Brookfield Infrastructure has adopted IFRS effective January 1, 2010. Prior to the adoption of IFRS Brookfield Infrastructure prepared its financial statements in accordance with U.S. Generally Accepted Accounting Principles (GAAP). These are Brookfield Infrastructure's first annual consolidated and combined financial statements prepared in accordance with IFRS. Brookfield Infrastructure's transition date was January 1, 2009 (the "transition date") and Brookfield Infrastructure has prepared its opening IFRS Statements of Financial Position as at that date.

In preparing these consolidated and combined financial statements in accordance with IFRS 1 First-time Adoption of International Financial Reporting Standards ("IFRS 1"), Brookfield Infrastructure has applied certain of the optional exemptions from full retrospective application of IFRS. The optional exemptions applied are described below.

Brookfield Infrastructure has elected to measure its property, plant and equipment of its North American transmission operation at fair value as at January 1, 2009, and use that amount as deemed cost as at January 1, 2009. The revaluation method will be applied to the North American transmission operation subsequent to the transition date.

Brookfield Infrastructure has elected to measure its land under standing timber at the date of transition to IFRS at its fair value and use that fair value as deemed cost as at that date. The revaluation method will be applied to its U.S. and Canadian freehold timberlands property, plant and equipment subsequent to the transition date.

Brookfield Infrastructure has elected to set the previously accumulated cumulative translation account, which is included in accumulated other comprehensive income, to zero at January 1, 2009. This exemption has been applied to all subsidiaries.

Brookfield Infrastructure has elected to apply the business combinations exemption in IFRS 1. Accordingly, it has not restated business combinations that took place prior to the January 1, 2009, IFRS transition date.

In preparing these consolidated and combined financial statements in accordance with IFRS 1, Brookfield Infrastructure has applied certain mandatory exceptions from full retrospective application of IFRS. The mandatory exceptions applied from full retrospective application of IFRS are described below.

Only hedging relationships that satisfied the hedge accounting criteria as of the transition date are reflected as hedges in Brookfield Infrastructure's results under IFRS. Any derivatives not meeting the IAS 39 Financial Instruments: Recognition and Measurement criteria for hedge accounting were recorded as a non-hedging derivative financial instrument.

Brookfield Infrastructure from time to time enters into derivative contracts to hedge against foreign currency risks on certain cash flows that do not qualify for hedge accounting.

Hindsight was not used to create or revise estimates and accordingly the estimates previously made by Brookfield Infrastructure under U.S. GAAP are consistent with their application under IFRS.

The preparation of financial statements in conformity with IFRS requires management to select appropriate accounting policies and to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. In particular, critical accounting policies and estimates utilized in the normal course of preparing our partnership's financial statements require the determination of the fair value of property, plant and equipment; the fair value of standing timber; the fair value of investment property; the impairment of goodwill and intangibles with indefinite lives; the fair values in business combinations; and the estimation of useful lives of assets of property, plant and equipment.

In making estimates, management relies on external information and observable conditions where possible, supplemented by internal analysis as required. These estimates have been applied in a manner consistent with that in a prior year, and there are no known trends, commitments, events or uncertainties that we believe will materially affect the methodology or assumptions utilized in this report. The estimates are impacted by, among other things, movements in interest rates, foreign exchange and other factors, some of which are highly uncertain. The interrelated nature of these factors prevents us from quantifying the overall impact of these movements on our partnership's financial statements in a meaningful way. These sources of estimation uncertainty relate in varying degrees to virtually all asset and liability account balances.

IFRS 3R does not include specific measurement guidance for transfers of businesses or subsidiaries between entities under common control. Accordingly, Brookfield Infrastructure has a policy to account for such transactions taking into consideration other guidance in the IFRS framework and pronouncements of other standard-setting bodies. The partnership's policy is to record assets and liabilities recognized as a result of transactions between entities under common control at the carrying value on the transferor's financial statements. The Statements of Operating Results reflect the results of combining entities for all periods presented for which the entities were under the transferors control, irrespective of when the combination takes place.

Property, plant and equipment measured using the revaluation method are initially measured at cost and subsequently carried at their revalued amount, being the fair value at the date of the revaluation less any subsequent accumulated depreciation and any accumulated impairment losses. Revaluations are made on a regular basis to ensure that the carrying amount does not differ significantly from fair value. Where the carrying amount of an asset is increased as a result of a revaluation, the increase is recognized in income to the extent the increase reverses a previously recognized impairment recorded through income, with the remainder of the increase recognized in other comprehensive income and accumulated in partnership capital in revaluation surplus. Where the carrying amount of an asset is decreased, the decrease is recognized in other comprehensive income to the extent of any balance existing in revaluation surplus in respect of the asset, with the remainder of the decrease recognized in income.

Standing timber is measured at fair value after deducting estimated selling costs and recorded as timber on the Statements of Financial Position. Estimated selling costs include commissions, levies, delivery costs, transfer taxes and duties. The fair value of standing timber is calculated as the present value of anticipated future cash flows for standing timber before tax. The calculation is based on existing, sustainable felling plans and assessments regarding growth, timber prices and felling and silviculture costs. The discount rate is based upon a normal timberland owner's weighted average cost of capital before tax for the geographic location of the standing timber. Changes in fair value are recorded in net income during the period of change. Brookfield Infrastructure determines fair value using external valuations on an annual basis.

Intangible assets acquired in a business combination and recognized separately from goodwill are initially recognized at their fair value at the acquisition date. The partnership's intangible assets are comprised of conservancy rights and service concession arrangements.

The conservancy right was acquired as part of the acquisition of UK Port operation and was recorded at its fair value. As a right in perpetuity issued by the Statutory Harbour Authority in the UK, the conservancy right is classified as having an indefinite life.

Brookfield Infrastructure designates certain hedging instruments, which include derivatives, embedded derivatives and non-derivatives in respect of foreign currency risk, as either fair value

hedges, cash flow hedges, or hedges of net investments in foreign operations. Hedges of foreign exchange risk on firm commitments are accounted for as cash flow hedges.

At the inception of the hedge relationship, the entity documents the relationship between the hedging instrument and hedged item, along with its risk management objectives and its strategy for undertaking various hedge transactions. Furthermore, at the inception of the hedge and on an ongoing basis, Brookfield Infrastructure documents whether the hedging instrument that is used in a hedging relationship is highly effective in offsetting changes in fair values, net investment values, or cash flows of the hedged item.

Realized and unrealized gains and losses on foreign exchange contracts, designated as hedges of currency risks relating to a net investment in a subsidiary with a functional currency other than the U.S. dollar are included in partnership capital and are included in net income in the period in which the subsidiary is disposed of, or to the extent partially disposed and control is not retained. Derivative financial instruments that are designated as hedges to offset corresponding changes in the fair value of assets and liabilities and cash flows are measured at estimated fair value, with changes in fair value recorded in net income or as a component of partnership capital as applicable.

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognized in income or loss immediately, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk.

Hedge accounting is discontinued when Brookfield Infrastructure revokes the hedging relationship, when the hedging instrument expires or is sold, terminated, or exercised, or no longer qualifies for hedge accounting. The fair value adjustment to the carrying amount of the hedged item arising from the hedged risk is amortized to income or loss from that date.

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges are deferred in other comprehensive income. The gain or loss relating to the ineffective portion is recognized immediately in income or loss.

Amounts previously recognized in other comprehensive income and accumulated in partnership capital are reclassified to income or loss in the periods when the hedged item is recognized in income or loss, in the same line of the Statements of Operating Results as the recognized hedged item. However, when the forecast transaction that is hedged results in the recognition of a non-financial asset or a non-financial liability, the gains and losses previously accumulated in partnership capital are included in the initial measurement of the cost of the non-financial asset or non-financial liability.

Hedge accounting is discontinued when Brookfield Infrastructure revokes the hedging relationship, when the hedging instrument expires or is sold, terminated, or exercised, or no longer qualifies for hedge accounting. Any gain or loss accumulated in partnership capital at that time remains in partnership capital and is recognized when the forecast transaction is ultimately recognized in income or loss. When a forecast transaction is no longer expected to occur, the gain or loss accumulated in partnership capital is recognized immediately in income or loss.

To measure performance, we focus on net income as well as FFO. We define FFO as net income excluding the impact of depreciation, depletion and amortization, deferred taxes and other items as shown in the reconciliation below. For our social infrastructure operations we also subtract debt amortization from FFO as these are finite life concessions and debt must be fully amortized during the concession term. FFO is a measure of operating performance that is not calculated in accordance with, and does not have any standardized meaning prescribed by IFRS. FFO is therefore unlikely to be comparable to similar measures presented by other issuers. FFO has limitations as an analytical tool:

Because of these limitations, FFO should not be considered as the sole measure of our performance and should not be considered in isolation from, or as a substitute for, analysis of our results as reported under IFRS. We compensate for these limitations by relying on our IFRS results and using FFO only supplementally. However, FFO is a key measure that we use to evaluate the performance of our operations and forms the basis for our Partnership's distribution policy.

When viewed with our IFRS results, we believe that FFO provides a more complete understanding of factors and trends affecting our underlying operations. FFO allows us to evaluate our businesses on the basis of cash return on net capital deployed by removing the effect of non-cash and other items. We add back depreciation and amortization to remove the implication that our assets decline in value over time since we believe that the value of most or our assets will typically increase over time provided we make all necessary maintenance expenditures.

We add back depletion because we endeavor to manage our U.S. and Canadian freehold timberlands on a sustainable basis over the long term. Furthermore, changes in asset values typically do not decline on a predetermined schedule, as suggested by accounting depreciation or depletion, but instead will inevitably vary upwards and downwards based on a number of market and other conditions that cannot be determined in advance. We add back deferred income taxes because we do not believe this item reflects the present value of the actual cash tax obligations we will be required to pay, particularly if our operations are held for a long period of time. We add back fair value adjustments and mark-to-market adjustments recorded in net income as these are non-cash in nature and indicate a point in time approximation of value on long-term items. Finally, we add back a performance fee payable to Brookfield by Island Timberlands. This performance fee was calculated based upon a percentage of the increased appraised value of the renewable resources and HBU land assets held by our Canadian freehold timberland over a threshold level. We believe it is appropriate to measure our performance excluding the impact of this accrual as we expect that over time the financial impact of this fee will be more than offset by increased income associated with the increased appraised value of these assets, a benefit which is not reflected in the period in which the related fee accrues. In addition, as a result of our fee-netting mechanism, which is designed to eliminate any duplication of fees, any performance fees will reduce future incentive distributions that may otherwise be made to Brookfield by our partnership. As this credit is reflected as a reduction in distributions to Brookfield, it would not be reflected in FFO without adding back the performance fee.

In addition, we focus on adjusted funds from operations or AFFO, which is defined as FFO less maintenance capital expenditures. Management uses AFFO as a measure of long-term sustaining cash flow.

The following table reconciles FFO to the most directly comparable IFRS measure, which is net income. We urge you to review the IFRS financial measures within the MD&A and to not rely on any single financial measure to evaluate the Partnership.

		For the Year Ended December 31,

MILLIONS, UNAUDITED		2010			2009
Net income attributable to partnership		$	467		$	25
Add back or deduct the following:
	Depreciation, depletion and amortization		132			26
	Unrealized losses on derivative instruments		18			15
	Performance fees		—			(5	)
	Fair value adjustments		18			66
	Fair value gain and other items		(433	)		—
	Deferred taxes		(5	)		(10	)

FFO			197			117
Maintenance capital			(49	)		(18	)

AFFO		$	148		$	99

The difference between net income and FFO is primarily attributable to depreciation and depletion expense, as well as the gain associated with the Merger Transaction. The difference between net income and AFFO is primarily attributable to depreciation and depletion expense, the gain associated with the Merger Transaction, and maintenance capital expenditures.

In order to assess our performance as stewards of capital, AFFO yield is defined as AFFO divided by the capital that we invest in our business (invested capital). We define invested capital as partnership capital adding back the following items: maintenance capital expenditures, non-cash income statement items and other comprehensive income as shown in the reconciliation below. Invested capital is a measure that is not calculated in accordance with, and does not have any standardized meaning prescribed by IFRS. Invested capital is therefore unlikely to be comparable to similar measures presented by other issues. Invested capital has limitations as a tool to measure returns on capital invested as follows:

Because of these limitations, invested capital should not be considered as the sole measure of our performance and should not be considered in isolation from, or as a substitute for, analysis of our results as reported under IFRS. We compensate for these limitations by relying on our IFRS results and using invested capital only supplementally. However, invested capital is a key measure that we use to evaluate the performance of our operations.

When viewed in conjunction with our IFRS results, we believe that invested capital provides a more complete understanding of the returns we earn on this capital that we invest. Invested capital allows us to evaluate our businesses on the basis of cash return on net capital deployed by removing the effect of non-cash impacts on our capital base. We add back maintenance capital expenditures in

order to capture the difference between depreciation and our sustaining capital investment which can be reinvested in our business. Minority interest is excluded as this represents capital invested by other shareholders. Non-cash income statement items are not included as these balances do not represent cash returned or reinvested in our assets. The impact of other comprehensive income is ignored as these adjustments to partnership capital represent changes such as fair value adjustments or non-cash gains or losses on foreign exchange that have not been realized by us.

The following table reconciles invested capital to the most directly comparable IFRS measure, which is partnership capital:

As required by law, our limited partnership agreement provides for the management and control of our partnership by a general partner rather than a board of directors and officers. Our Managing General Partner serves as our partnership's general partner and has a board of directors. Our Managing General Partner has no executive officers. Our Managing General Partner has sole responsibility and authority for the central management and control of our partnership, which is exercised through its board of directors in Bermuda.

The Service Recipients have entered into a Master Services Agreement pursuant to which the Manager and certain other affiliates of Brookfield Asset Management who are party thereto have agreed to provide or arrange for other service providers to provide management and administration services to our partnership and the other Service Recipients. The operating entities are not a party to the Master Services Agreement.

The following is a summary of certain provisions of our Master Services Agreement and is qualified in its entirety by reference to all of the provisions of the agreement. Because this description is only a summary of the Master Services Agreement, it does not necessarily contain all of the information that you may find useful. We therefore urge you to review the Master Services Agreement in its entirety. Copies of the Master Services Agreement are available electronically on the website of the Securities and Exchange Commission at www.sec.gov and are made available to our unitholders as described under Item 10.C "Material Contracts" and Item 10.H "Documents on display."

Under our Master Services Agreement, the Service Recipients have appointed the Manager, as the service provider, to provide or arrange for the provision by an appropriate service provider of the following services:

The Manager's activities are subject to the supervision of the board of directors of our Managing General Partner and of each of the other Service Recipients or their equivalent, as applicable.

Pursuant to the Master Services Agreement, on a quarterly basis, we pay a base management fee, referred to as the Base Management Fee, to the Manager 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 volume weighted average of the closing prices of our partnership's units on the NYSE (or other exchange or market where our partnership's units are principally traded) for each of the last five trading days of the applicable quarter multiplied by the number of issued and outstanding units of our partnership on the last of those days (assuming full conversion of Brookfield's interest in Brookfield Infrastructure into units of our partnership), plus the amount of third-party debt, net of cash, with recourse to our partnership, the Holding LP and any Holding Entity.

To the extent that under any other arrangement we are obligated to pay a base management fee (directly or indirectly through an equivalent arrangement) to the Manager (or any affiliate) on a portion of our capital that is comparable to the Base Management Fee, the Base Management Fee payable for each quarter in respect thereof will be reduced on a dollar for dollar basis by our proportionate share of the comparable base management fee (or equivalent amount) under such other arrangement for that quarter. The Base Management Fee will not be reduced by the amount of any incentive distribution payable by any Service Recipient or operating entity to the Manager (or any other affiliate) (for which there is a separate credit mechanism under the Holding LP's limited partnership agreement), or any other fees that are payable by any operating entity to Brookfield for financial advisory, operations and maintenance, development, operations management and other services. See Item 7.B "Related Party Transactions—Other Services" and Item 7.B "Related Party Transactions—Incentive Distributions."

We also reimburse the Manager for any out-of-pocket fees, costs and expenses incurred in the provision of the management and administration services. However, the Service Recipients are not required to reimburse the Manager for the salaries and other remuneration of its management, personnel or support staff who carry out any services or functions for such Service Recipients or overhead for such persons.

The relevant Service Recipient is required to pay the Manager all other out-of-pocket fees, costs and expenses incurred in connection with the provision of the services including those of any third party and to reimburse the Manager for any such fees, costs and expenses. Such out-of-pocket fees, costs and expenses include, among other things, (i) fees, costs and expenses relating to any debt or equity financing; (ii) out-of-pocket fees, costs and expenses incurred in connection with the general administration of any Service Recipient; (iii) taxes, licenses and other statutory fees or penalties levied against or in respect of a Service Recipient; (iv) amounts owed under indemnification, contribution or similar arrangements; (v) fees, costs and expenses relating to our financial reporting, regulatory filings and investor relations and the fees, costs and expenses of agents, advisors and other persons who provide services to or on behalf of a Service Recipient; and (vi) any other fees, costs and expenses incurred by the Manager that are reasonably necessary for the performance by the Manager of its duties and functions under the Master Services Agreement.

In addition, the Service Recipients are required to pay all fees, expenses and costs incurred in connection with the investigation, acquisition, holding or disposal of any acquisition that is made or that is proposed to be made by us. Where the acquisition or proposed acquisition involves a joint acquisition that is made alongside one or more other persons, the Manager will be required to allocate such fees, costs and expenses in proportion to the notional amount of the acquisition made (or that would have been made in the case of an unconsummated acquisition) among all joint investors. Such

additional fees, expenses and costs represent out-of-pocket costs associated with investment activities that are undertaken pursuant to the Master Services Agreement.

The Service Recipients are also required to pay or reimburse the Manager for all sales, use, value added, withholding or other taxes or customs duties or other governmental charges levied or imposed by reason of the Master Services Agreement or any agreement it contemplates, other than income taxes, corporation taxes, capital taxes or other similar taxes payable by the Manager, which are personal to the Manager.

The Master Services Agreement has no fixed term. However, the Service Recipients may terminate the Master Services Agreement upon 30 days' prior written notice of termination from our Managing General Partner to the Manager if any of the following occurs:

The Service Recipients have no right to terminate for any other reason, including if the Manager or Brookfield experiences a change of control. The Managing General Partner may only terminate the Master Services Agreement on behalf of our partnership with the prior unanimous approval of the Managing General Partner's independent directors.

Our Master Services Agreement expressly provides that the agreement may not be terminated by our Managing General Partner due solely to the poor performance or the underperformance of any of our operations.

The Manager may terminate the Master Services Agreement upon 30 days' prior written notice of termination to our Managing General Partner if any Service Recipient 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 and the default continues unremedied for a period of 30 days after written notice of the breach is given to the Service Recipient. The Manager may also terminate the Master Services Agreement upon the occurrence of certain events relating to the bankruptcy or insolvency of our partnership.

If the Master Services Agreement is terminated, the licensing agreement, the Relationship Agreement and any of Brookfield's obligations under the Relationship Agreement would also terminate. See Item 7.B "Related Party Transactions—Relationship Agreement" and Item 3.D "Risk Factors—Risks Relating to Our Relationship with Brookfield."

Under the Master Services Agreement, the Manager has not assumed and will not assume any responsibility other than to provide or arrange for the provision of the services called for thereunder in good faith and will not be responsible for any action that the Service Recipients take in following or declining to follow the advice or recommendations of the Manager. The maximum amount of the aggregate liability of the Manager or any of its affiliates, or of any director, officer, employee,

contractor, agent, advisor or other representative of the Manager or any of its affiliates, will be equal to the Base Management Fee previously paid by the Service Recipients in the two most recent calendar years pursuant to the Master Services Agreement. The Service Recipients have also agreed to indemnify each of the Manager, Brookfield and their directors, officers, agents, members, partners, shareholders and employees to the fullest extent permitted by law from and against any claims, liabilities, losses, damages, costs or expenses (including legal fees) incurred by an indemnified person or threatened in connection with our respective businesses, investments and activities or in respect of or arising from the Master Services Agreement or the services provided by the Manager, except to the extent that the claims, liabilities, losses, damages, costs or expenses are determined to have resulted from the indemnified person's bad faith, fraud or willful misconduct, or in the case of a criminal matter, action that the indemnified person knew to have been unlawful. In addition, under the Master Services Agreement, the indemnified persons will not be liable to the Service Recipients to the fullest extent permitted by law, except for conduct that involved bad faith, fraud, willful misconduct, gross negligence or in the case of a criminal matter, action that the indemnified person knew to have been unlawful.

Our Master Services Agreement does not prohibit the Manager or its affiliates from pursuing other business activities or providing services to third parties that compete directly or indirectly with us. For a description of related aspects of the relationship between Brookfield and the Service Recipients, see Item 7.B "Related Party Transactions—Relationship Agreement."

Our Managing General Partner pays each of its directors $50,000 per year for serving on its board of directors and various board committees. The Managing General Partner pays the chairperson of the board of directors $100,000 per year for serving as chairperson of its board of directors.

Our Managing General Partner does not have any employees. Our partnership has entered into a Master Services Agreement with the Manager pursuant to which the Manager and certain other affiliates of Brookfield provide or arrange for other service providers to provide day-to-day management and administrative services for our partnership, the Holding LP and the Holding Entities. The fees payable under the Master Service Agreement are set forth under Item 6.A "Directors and Senior Management—Our Master Services Agreement—Management Fee." In addition, Brookfield is entitled to receive incentive distributions from the Holding LP described under Item 7.B "Related Party Transactions—Incentive Distributions."

Pursuant to the Master Service Agreement, members of Brookfield's senior management and other individuals from Brookfield's global affiliates are drawn upon to fulfill obligations under the Master Service Agreement. However, these individuals, including the Brookfield employees identified in the table under Item 6.A "Directors and Senior Management—Our Management," are not compensated by our partnership or our Managing General Partner. Instead, they will continue to be compensated by Brookfield. These individuals are not directors or officers of the partnership or our Managing General Partner.

The structure, practices and committees of our Managing General Partner's board of directors, including matters relating to the size, independence and composition of the board of directors, the election and removal of directors, requirements relating to board action and the powers delegated to board committees, are governed by our Managing General Partner's By-laws. Our Managing General

Partner's board of directors is responsible for exercising the management, control, power and authority of the Managing General Partner except as required by applicable law or the By-laws of the Managing General Partner. The following is a summary of certain provisions of those By-laws that affect our partnership's governance.

Our Managing General Partner's board of directors is currently set at eight directors. The board may consist of between three and 11 directors or such other number of directors as may be determined from time-to-time by a resolution of our Managing General Partner's shareholders and subject to its By-laws. At least three directors and at least a majority of the directors holding office must be independent of our Managing General Partner and Brookfield, as determined by the full board of directors using the standards for independence established by the NYSE.

If the death, resignation or removal of an independent director results in the board of directors consisting of less than a majority of independent directors, the vacancy must be filled promptly. Pending the filling of such vacancy, the board of directors may temporarily consist of less than a majority of independent directors and those directors who do not meet the standards for independence may continue to hold office. In addition, our Managing General Partner's By-laws provide that not more than 50% of the directors (as a group) or the independent directors (as a group) may be residents of any one jurisdiction (other than Bermuda and any other jurisdiction designated by the board of directors from time to time).

Our Managing General Partner's board of directors was appointed by its shareholders and each of its current directors will serve until the close of the next annual meeting of shareholders of our Managing General Partner or his or her death, resignation or removal from office, whichever occurs first. Vacancies on the board of directors may be filled and additional directors may be added by a resolution of our Managing General Partner's shareholders or a vote of the directors then in office. A director may be removed from office by a resolution duly passed by our Managing General Partner's shareholders or, if the director has been absent without leave from three consecutive meetings of the board of directors, by a written resolution requesting resignation signed by all other directors then holding office. A director will be automatically removed from the board of directors if he or she becomes bankrupt, insolvent or suspends payments to his or her creditors or becomes prohibited by law from acting as a director.

Our Managing General Partner's board of directors may take action in a duly convened meeting at which a quorum is present or by a written resolution signed by all directors then holding office. Our Managing General Partners' board of directors holds a minimum of four meetings per year. When action is to be taken at a meeting of the board of directors, the affirmative vote of a majority of the votes cast is required for any action to be taken.

Our Managing General Partner's independent directors have approved a conflicts policy which addresses the approval and other requirements for transactions in which there is greater potential for a conflict of interest to arise. These transactions include:

Our conflicts policy requires the transactions described above to be approved by a majority of our Managing General Partner's independent directors. Pursuant to our conflicts policy, independent directors may grant approvals for any of the transactions described above in the form of general guidelines, policies or procedures in which case no further special approval will be required in connection with a particular transaction or matter permitted thereby. See Item 7.B "Related Party Transactions—Conflicts of Interest and Fiduciary Duties."

A director who directly or indirectly has an interest in a contract, transaction or arrangement with our Managing General Partner, our partnership or certain of our affiliates is required to disclose the nature of his or her interest to the full board of directors. Such disclosure may generally take the form of a general notice given to the board of directors to the effect that the director has an interest in a specified company or firm and is to be regarded as interested in any contract, transaction or arrangement which may after the date of the notice be made with that company or firm or its affiliates. A director may participate in any meeting called to discuss or any vote called to approve the transaction in which the director has an interest and any transaction approved by the board of directors will not be void or voidable solely because the director was present at or participates in the meeting in which the approval was given provided that the board of directors or a board committee authorizes the transaction in good faith after the director's interest has been disclosed or the transaction is fair to our Managing General Partner and our partnership at the time it is approved.

There are no service contracts with directors that provide benefit upon termination of employment.

Our Managing General Partner's board of directors is required to establish and maintain at all times an audit committee that operates pursuant to a written charter. The audit committee is required to consist solely of independent directors and each member must be financially literate and there will be at least one member designated as an audit committee financial expert. Not more than 50% of the audit committee members may be directors who are residents of any one jurisdiction (other than Bermuda and any other jurisdiction designated by the board of directors from time to time).

The audit committee is responsible for assisting and advising our Managing General Partner's board of directors with matters relating to:

The audit committee is also responsible for engaging our independent accountants, reviewing the plans and results of each audit engagement with our independent accountants, approving professional services provided by our independent accountants, considering the range of audit and non-audit fees charged by our independent accountants and reviewing the adequacy of our internal accounting controls. The audit committee charter is available on our website at www.brookfieldinfrastructure.com/aboutus/governance and is available upon written request from our Corporate Secretary, at Canon's Court, 22 Victoria Street, Hamilton HM 12, Bermuda.

Our Managing General Partner's board of directors is required to establish and maintain at all times a nominating and governance committee that operates pursuant to a written charter. The nominating and governance committee is required to consist entirely of independent directors and not more than 50% of the nominating and corporate governance committee members may be directors who are residents of any one jurisdiction (other than Bermuda and any other jurisdiction designated by the board of directors from time to time).

The nominating and governance committee is responsible for approving the appointment by the sitting directors of a person to the office of director and for recommending a slate of nominees for election as directors by our Managing General Partner's shareholders. The nominating and governance committee is also responsible for assisting and advising our Managing General Partner's board of directors with respect to matters relating to the general operation of the board of directors, our partnership's governance, the governance of our Managing General Partner and the performance of its board of directors and individual directors. The nominating and governance committee charter is available on our website at www.brookfieldinfrastructure.com/aboutus/governance and is available upon written request from our Corporate Secretary, at Canon's Court, 22 Victoria Street, Hamilton HM 12, Bermuda.

Our Managing General Partner's board of directors is required to establish and maintain at all times a compensation committee that operates pursuant to a written charter. The compensation committee is required to consist solely of independent directors. Not more than 50% of the compensation committee members may be directors who are residents of any one jurisdiction (other than Bermuda and any other jurisdiction designated by the board of directors from time to time).

The compensation committee is responsible for reviewing and making recommendations to the board of directors of the Managing General Partner concerning the remuneration of directors and committee members and supervising any changes in the fees to be paid pursuant to the Master Services Agreement. The compensation committee charter is available on our website at www.brookfieldinfrastructure.com/aboutus/governance and is available upon written request from our Corporate Secretary, at Canon's Court, 22 Victoria Street, Hamilton HM 12, Bermuda.

Bermuda law permits the partnership agreement of a limited partnership, such as our partnership, to provide for the indemnification of a partner, the officers and directors of a partner and any other person against any and all claims and demands whatsoever, except to the extent that the indemnification may be held by the courts of Bermuda to be contrary to public policy or to the extent that Bermuda law prohibits indemnification against personal liability that may be imposed under specific provisions of Bermuda law. Bermuda law also permits a partnership to pay or reimburse an indemnified person's expenses in advance of a final disposition of a proceeding for which

indemnification is sought. See Item 10.B "Memorandum and Articles of Association—Description of Our Units and Our Limited Partnership Agreement—Indemnification; Limitations on Liability" for a description of the indemnification arrangements in place under our limited partnership agreement.

Bermuda law permits the By-laws of an exempted company, such as our Managing General Partner, to provide for the indemnification of its officers, directors and shareholders and any other person designated by the company against any and all claims and demands whatsoever, except to the extent that the indemnification may be held by the courts of Bermuda to be contrary to public policy or to the extent that Bermuda law prohibits indemnification against personal liability that may be imposed under specific provisions of Bermuda law. Bermuda company law also permits an exempted company to pay or reimburse an indemnified person's expenses in advance of a final disposition of a proceeding for which indemnification is sought.

Under our Managing General Partner's By-laws, our Managing General Partner is required to indemnify, to the fullest extent permitted by law, its affiliates, directors, officers, resident representative, shareholders and employees, any person who serves on a governing body of the Holding LP or any of its subsidiaries and certain others against any and all losses, claims, damages, liabilities, costs or expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, incurred by an indemnified person in connection with our partnership's investments and activities or in respect of or arising from their holding such positions, except to the extent that the claims, liabilities, losses, damages, costs or expenses are determined to have resulted from the indemnified person's bad faith, fraud or willful misconduct, or in the case of a criminal matter, action that the indemnified person knew to have been unlawful. In addition, under our Managing General Partner's By-laws, (i) the liability of such persons has been limited to the fullest extent permitted by law and except to the extent that their conduct involves bad faith, fraud or willful misconduct, or in the case of a criminal matter, action that the indemnified person knew to have been unlawful; and (ii) any matter that is approved by the independent directors will not constitute a breach of any duties stated or implied by law or equity, including fiduciary duties. Our Managing General Partner's By-laws require it to advance funds to pay the expenses of an indemnified person in connection with a matter in which indemnification may be sought until it is determined that the indemnified person is not entitled to indemnification.

Our partnership has obtained insurance coverage under which the directors of our Managing General Partner are insured, subject to the limits of the policy, against certain losses arising from claims made against such directors by reason of any acts or omissions covered under the policy in their respective capacities as directors of our Managing General Partner, including certain liabilities under securities laws.

Our partnership is not subject to Canadian insider reporting requirements due to its status as a "SEC Foreign Issuer" under Canadian securities laws. However, our partnership does not rely on the exemption that is available to it from the insider reporting requirements of Canadian securities laws.

The board of directors of the Infrastructure General Partner is identical to the board of directors of our Managing General Partner and has substantially similar governance arrangements as our partnership. However, the Infrastructure General Partner's By-laws allow for alternate directors. A director of the Infrastructure General Partner may by written notice to the secretary of the

Infrastructure General Partner appoint any person, including another director, who meets any minimum standards that are required by applicable law to serve as an alternate director to attend and vote in the director's place at any meeting of the Infrastructure General Partner's board of directors at which the director is not personally present and to perform any duties and functions and exercise any rights that the director could perform or exercise personally. Any alternate director appointed may not be a resident of a jurisdiction if such residency would cause more than 50% of the directors (as a group) or the independent directors (as a group) to consist of directors who are residents of any one jurisdiction (other than Bermuda and any other jurisdiction designated by the board of directors from time to time).

Each of our directors and officers of the Managing General Partner own less than one percent of our units.

The following table presents information regarding the beneficial ownership of our units by each entity that we know beneficially owns more than 5% of our units, as at December 31, 2010.

(1): Assumes that all of the Redeemable Partnership Units are exchanged for our units pursuant to the Redemption Exchange Mechanism described at Item 10.B "Memorandum and Articles of Association—Description of the Holding LP's Limited Partnership Agreement—Redemption Exchange Mechanism."
(2): Brookfield Asset Management may be deemed to be the beneficial owner of 43,445,572 of our units that it holds through wholly-owned subsidiaries, constituting approximately 27.8% of the issued and outstanding units, assuming that all of the Redeemable Partnership Units are exchanged for our units pursuant to the Redemption Exchange Mechanism described at Item 10.B "Memorandum and Articles of Association—Description of the Holding LP's Limited Partnership Agreement—Redemption Exchange Mechanism." This includes 48,930 of our units beneficially held by Brookfield Asset Management.
(3): Partners Limited owns all of Brookfield Asset Management's Class B Limited Voting Shares and approximately 50% of BAM Investment Corp.'s common shares. Partners Limited may be deemed to be the beneficial owner of 45,684,516 of our units, constituting approximately 29.2% of the issued and outstanding units, assuming that all of the Redeemable Partnership Units are

Our major unitholders have the same voting rights as all other holders of our units.

As of January 31, 2011, 112,964,451 of our outstanding units were held by 18,855 holders of record in the United States, not including units held of record by Depository Trust and Clearance Corporation, or DTC. As of January 31, 2011, DTC was the holder of record of 96,732,487 limited partnership units.

See also the information contained in this annual report on Form 20-F under Item 3.D "Risk Factors—Risks Relating to our Relationship with Brookfield," Item 6.C "Board Practices," Item 6.A "Directors and Senior Management" and Item 7.B "Related Party Transactions."

We are an affiliate of Brookfield. We have entered into a number of agreements and arrangements with Brookfield in order to enable us to be established as a separate entity and pursue our vision of being a leading owner and operator of high quality infrastructure assets. While we believe that this ongoing relationship with Brookfield provides us with a strong competitive advantage as well as access to opportunities that would otherwise not be available to us, we operate very differently from an independent, stand-alone entity. We describe below these relationships as well as potential conflicts of interest (and the methods for resolving them) and other material considerations arising from our relationship with Brookfield.

Our partnership, the Holding LP, the Holding Entities, the Manager and Brookfield have entered into an agreement, referred to as the Relationship Agreement, that governs aspects of the relationship among them. Pursuant to the Relationship Agreement, Brookfield has agreed that we serve as the primary (though not exclusive) vehicle through which Brookfield makes future infrastructure related acquisitions that are suitable for our strategy and objectives. Our acquisition strategy focuses on large scale transactions, for which we believe there is less competition and where Brookfield has sufficient influence or control so that our operations-oriented approach can be deployed to create value. Due to similar asset characteristics and capital requirements we believe that the infrastructure industry will evolve like the real estate industry in which assets are commonly owned through consortiums and partnerships of institutional equity investors and owner/operators such as ourselves. Accordingly, 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. Brookfield has a strong track record of leading such consortiums and partnerships and actively managing underlying assets to improve performance. Brookfield agreed that it will not sponsor such arrangements that are suitable for us in the infrastructure sector unless we are given an opportunity to participate.

Brookfield's commitment to us and our ability to take advantage of opportunities is subject to a number of inherent limitations such as our financial capacity, the suitability of the acquisition in terms of the underlying asset characteristics and its fit with our strategy, limitations arising from the tax and regulatory regimes that govern our affairs and certain other restrictions. See Item 3.D "Risk Factors—Risks Relating to Our Relationship with Brookfield." Under the terms of the Relationship Agreement, our partnership, the Holding LP and the Holding Entities acknowledge and agree that, subject to providing us the opportunity to participate on the basis described above, Brookfield (including its directors, officers, agents, members, partners, shareholders and employees) is able to pursue other business activities and provide services to third parties that compete directly or indirectly with us. In addition, Brookfield has established or advised, and may continue to establish or advise, other entities that rely on the diligence, skill and business contacts of Brookfield's professionals and the information and acquisition opportunities they generate during the normal course of their activities. Our partnership, the Holding LP and the Holding Entities acknowledge and agree that some of these entities may have objectives that overlap with our objectives or may acquire infrastructure assets or businesses that could be considered appropriate acquisitions for us, and that Brookfield may have greater financial incentives to assist those other entities over us. Due to the foregoing, we expect to compete from time-to-time with Brookfield or other third parties for access to the benefits that we expect to realize from Brookfield's involvement in our business.

Since Brookfield has large, well established operations in real estate and renewable power that are separate from us, Brookfield will not be obligated to provide us with any opportunities in these sectors. In addition, since Brookfield has granted an affiliate the right to act as the exclusive vehicle for Brookfield's timberland acquisitions in Eastern Canada and the Northeastern U.S., we will not be entitled to participate in timberland acquisitions in those geographic regions. Brookfield also recently appointed an affiliate as its exclusive vehicle for the acquisition of contracted hydro and wind power generation facilities located in Canada. In the event of the termination of the Master Services Agreement, the Relationship Agreement would also terminate, including Brookfield's commitments to provide us with acquisition opportunities, as described above.

Pursuant to the Relationship Agreement, Brookfield has also agreed that any voting rights with respect to any operating entity that are held by entities over which it has control will be voted:

For these purposes, the relevant entity may maintain, from time-to-time, an approved slate of nominees or provide direction with respect to the approval or rejection of any matter in the form of general guidelines, policies or procedures in which case no further approval or direction will be required. Any such general guidelines, policies or procedures may be modified by the relevant entity in its discretion.

Under the Relationship Agreement, our partnership, the Holding LP and the Holding Entities have agreed that none of Brookfield or the Manager, nor any director, officer, agent, member, partner, shareholder or employee of Brookfield or the Manager, will be liable to us for any claims, liabilities,

losses, damages, costs or expenses (including legal fees) arising in connection with the business, investments and activities in respect of or arising from the Relationship Agreement. The maximum amount of the aggregate liability of Brookfield, or of any director, officer, employee, contractor, agent, advisor or other representative of Brookfield, will be equal to the amounts previously paid in the two most recent calendar years by the Service Recipients pursuant to the Master Services Agreement.

Our partnership and Brookfield have entered into voting agreements, or the Voting Agreements, that permit (i) our partnership, through our Managing General Partner, to direct all eligible votes in the election of the directors of the Infrastructure General Partner, through which our partnership participates in the management and activities of the Holding LP and the Holding Entities, and (ii) our partnership or our partnership's designated affiliates to direct all eligible votes in the election of directors of the following entities, which control entities in which we have an interest:

Pursuant to the Voting Agreements, Brookfield has agreed that any voting rights with respect to the above noted entities will be voted in favor of the election of directors approved by our partnership or our partnership's designated affiliates, as applicable. For these purposes, our partnership or our partnership's designated affiliates, as applicable, may maintain, from time-to-time, an approved slate of nominees or provide direction with respect to the approval or rejection of any matter in the form of general guidelines, policies or procedures in which case no further approval or direction will be required. Any such general guidelines, policies or procedures may be modified by our partnership or our partnership's designated affiliates, as applicable, in their discretion.

In addition, pursuant to the Voting Agreement relating to the Infrastructure General Partner, Brookfield has also agreed that any voting rights with respect to the Infrastructure General Partner, the Infrastructure GP LP and the Holding LP will be voted in accordance with the direction of our partnership with respect to the approval or rejection of the following matters relating to any such entity, as applicable: (i) any sale of all or substantially all of its assets, (ii) any merger, amalgamation, consolidation, business combination or other material corporate transaction, except in connection with any internal reorganization that does not result in a change of control, (iii) any plan or proposal for a complete or partial liquidation or dissolution, or any reorganization or any case, proceeding or action seeking relief under any existing laws or future laws relating to bankruptcy or insolvency, (iv) any amendment to the limited partnership agreement of Infrastructure GP LP or the Holding LP or (v) any commitment or agreement to do any of the foregoing.

In addition, pursuant to the Voting Agreements, Brookfield has agreed that it will not exercise its right under the limited partnership agreements for certain entities (including the Infrastructure GP LP) to remove the general partner of such entities except with the prior consent of our partnership.

Each Voting Agreement terminates (i) at such time that we cease to own any interest in the relevant entity, (ii) at such time that the Managing General Partner (or its successors or permitted assigns) involuntarily ceases to be the general partner of our partnership, (iii) at such time that that the Infrastructure GP LP (or its successors or permitted assigns) involuntarily ceases to be the general partner of the Holding LP, or (iv) at such time that that the Infrastructure General Partner (or its successors or permitted assigns) involuntarily ceases to be the general partner of the Infrastructure GP LP. In addition, we are permitted to terminate the Voting Agreements upon 30 days

notice. The termination of a Voting Agreement with respect to one or more entity will not affect the validity or enforceability of the Voting Agreements with respect to any other entity.

The Voting Agreements also contain restrictions on transfers of the shares that Brookfield has agreed to vote in favor of the election of directors approved by our partnership or our partnership's designated affiliates, as applicable.

The Service Recipients have entered into the Master Services Agreement pursuant to which the Manager and certain other affiliates of Brookfield Asset Management who are party thereto agreed to provide or arrange for other service providers to provide management and administration services to our partnership and the other Service Recipients. For example, Samuel Pollock, in his capacity as the Chief Executive Officer of the Manager, and John Stinebaugh, in his capacity as the Chief Financial Officer of the Manager, are the persons who perform the functions of our partnership's principal executive officer and principal financial officer, respectively. In exchange, the Manager is entitled to a Base Management Fee. For a description of our Master Services Agreement, see Item 6.A "Directors and Senior Management—Our Master Services Agreement."

Brookfield may provide to the operating entities services which are outside the scope of the Master Services Agreement under arrangements that are on market terms and conditions and pursuant to which Brookfield will receive fees. The services provided under these arrangements include financial advisory, operations and maintenance, development, operations management and other services. Pursuant to our conflict of interest guidelines, those arrangements may require prior approval by a majority of the independent directors, which may be granted in the form of general guidelines, policies or procedures. See "—Conflicts of Interest and Fiduciary Duties."

On August 23, 2010, our partnership and the Managing General Partner entered into an implementation agreement, or the Merger Transaction Agreement, with Prime and certain other parties thereto under which, pursuant to a scheme of arrangement, or the Scheme, each Prime securityholder on the register at the Scheme record date received 0.24 of our units and A$0.20 in consideration for each of Prime security held. Pursuant to the Scheme, our partnership acquired all of the Prime securities not held by us. In conjunction with the Scheme, our partnership also made a take-over bid, or the Bid, for all Prime securities. The Bid was conditional upon the Scheme not becoming effective. The following represents a summary only and reference should be made to the full text of the Merger Transaction Agreement, which can be found on the website of the United States Securities Exchange Commission at www.sec.gov.

Upon receipt of approval from the Australian courts, the Scheme, consisting of a scheme of arrangement under Part 5.1 of the Corporations Act 2001 (Australia), or the Company Scheme, and trust schemes under in accordance with Guidance Note 15 for the trust units of the Prime Securities, or the Trust Schemes, facilitated the acquisition of the outstanding 60.1% of Prime securities not held by us, in exchange for 0.24 of our units for each security of Prime. The Merger Transaction Agreement was amended on October 19, 2010 to add cash consideration of A$0.20 for each Prime Security not already held by us. In connection with the Scheme, to accommodate holders of smaller numbers of Prime Securities and holders in jurisdictions where the issuance of our units would be illegal or impractical, each Prime securityholder was able to elect (and in some jurisdictions was required) to participate in liquidity facilities, or the Voluntary Liquidity Facility and Compulsory Sale Facility, respectively, cash on the basis of $17.02 per unit in lieu of up to 4,000 of our units that they would

otherwise have been entitled to receive. The amount of cash was equal to the volume weighted average of the trading price for one of our units on the NYSE for the five trading days immediately preceding August 23, 2010, the date on which the Merger Transaction Agreement was signed (and was equal to the subscription price under the Equity Commitments). Cash available to fund the Voluntary Liquidity Facility was capped at $300 million and any excess of our units that Prime securityholders elect into the Voluntary Liquidity Facility would have been sold on the NYSE, and participating Prime securityholders would have received a blended price.

Prime Securityholders who were ineligible to receive our units due to illegality or impracticality, or Ineligible Foreign Securityholders, did not have the option to exchange Prime securities for our units. Rather, units that Ineligible Foreign Securityholders would otherwise be entitled to receive were sold through the Compulsory Sale Facility. However, since the above overall $300 million cash cap was not exhausted by the Voluntary Liquidity Facility, Ineligible Foreign Securityholders were paid from the surplus cash provided under equity commitments provided by Brookfield Asset Management of up to $300 million, in aggregate, or the Equity Commitments, at a price per unit equal to the volume weighted average of the trading price of our units over a period of 20 trading days on the NYSE beginning on a date specified by our partnership which was no later than the day falling five trading days prior to the date the Australian courts issued the order approving the Scheme and, to the extent required, any excess units that would otherwise have been issued to Ineligible Foreign Securityholders would have been sold on the NYSE, and Ineligible Foreign Securityholders would have received a blended price. The Company Scheme and Trust Schemes were inter-conditional so that each of the schemes would have had to have become effective in order for our partnership to acquire the Prime Securities.

In connection with the Voluntary Liquidity Facility and Ineligible Foreign Securityholders Facility, our Partnership paid approximately $17 million in cash consideration. For further information about the Merger Transaction, see Item 4.A "History and Development of Brookfield Infrastructure" and "—Equity Commitment and Other Financing".

Concurrent with the closing of the spin-off, Brookfield provided to our partnership and the Holding LP an equity commitment in the amount of $200 million, or the First Equity Commitment. The equity commitment could be called by our partnership and/or the Holding LP in exchange for the issuance of a number of units of our partnership or the Holding LP, as the case may be, to Brookfield, corresponding to the amount of the equity commitment called divided by the volume weighted average of the trading price for our units on the principal stock exchange on which our units are listed for the five days immediately preceding the date of the call. The equity commitment was available to be called until January 31, 2011.

In addition, on August 23, 2010, Brookfield provided to our partnership and the Holding LP an additional equity commitment, or the Second Equity Commitment, in the amount of $175 million on the same terms and conditions of the First Equity Commitment. Concurrent with execution of the Second Equity Commitment, our partnership and the Holding LP furnished Brookfield with draw-down notices pursuant to the First Equity Commitment and Second Equity Commitment in the amount of $125 million and $175 million, respectively. On December 6, 2010, our partnership and the Holding LP furnished Brookfield with supplemental draw-down notices pursuant to the First Equity Commitment and Second Equity Commitment, which reduced the draw under the Equity Commitments to $0 and $16,959,899.11, respectively. The funds drawn under the Second Equity Commitment were used to satisfy our partnership's obligations under the Voluntary Liquidity Facility and Ineligible Foreign Securityholders Facility (as described above). The Holding LP issued 926,422 Redeemable Partnership Units in consideration for the funds drawn under the Second Equity Commitment.

The units of the Holding LP that were issued under the equity commitment are subject to the Redemption-Exchange Mechanism and may therefore result in Brookfield acquiring additional units of our partnership. See Item 10.B "Memorandum and Articles of Association—Description of the Holding LP's Limited Partnership Agreement—Redemption-Exchange Mechanism."

Brookfield has provided an aggregate of $20 million of working capital to our Holding Entities through a subscription for preferred shares of such Holding Entities. The preferred shares are entitled to receive a cumulative preferential dividend equal to 6% of their redemption value as and when declared by the board of directors of the applicable Holding Entity and are redeemable at the option of the Holding Entity, subject to certain limitations, at any time after the tenth anniversary of their issuance. The preferred shares are not entitled to vote, except as required by law.

One or more wholly-owned subsidiaries of Brookfield Asset Management that hold Redeemable Partnership Units (as hereinafter defined) have the right to require Brookfield Infrastructure to redeem all or a portion of the Redeemable Partnership Units, subject to our partnership's right of first refusal, for cash in an amount equal to the market value of one of our units multiplied by the number of units to be redeemed (subject to certain adjustments). See Item 10.B "Memorandum and Articles of Association—Description of the Holding LP's Limited Partnership Agreement—Redemption-Exchange Mechanism." Taken together, the effect of the redemption right and the right of first refusal is that one or more wholly-owned subsidiaries of Brookfield will receive our units, or the value of such units, at the election of our partnership. Should our partnership determine not to exercise its right of first refusal, cash required to fund a redemption of limited partnership interests of the Holding LP held by wholly-owned subsidiaries of Brookfield will likely be financed by a public offering of our units.

Our partnership has entered into a registration rights agreement with Brookfield pursuant to which our partnership has agreed that, upon the request of Brookfield, our partnership will file one or more registration statements to register for sale under the United States Securities Act of 1933, as amended, any of our units held by Brookfield (including our units acquired pursuant to the Redemption-Exchange Mechanism). In the registration rights agreement we have agreed to pay expenses in connection with such registration and sales and have indemnified Brookfield for material misstatements or omissions in the registration statement.

Infrastructure GP LP is entitled to receive incentive distributions from the Holding LP as a result of its ownership of the general partnership interest in the Holding LP. The incentive distributions are to be calculated in increments based on the amount by which quarterly distributions on the limited partnership units of the Holding LP exceed specified target levels as set forth in the Holding LP's limited partnership agreement. See Item 10.B "Memorandum and Articles of Association—Description of the Holding LP's Limited Partnership Agreement—Distributions."

The Infrastructure GP LP may, at its sole discretion, elect to reinvest incentive distributions in exchange for Redeemable Partnership Units.

To the extent that any Holding Entity or any operating entity pays to Brookfield any comparable performance or incentive distribution, the amount of any future incentive distributions will be reduced in an equitable manner to avoid duplication of distributions.

For example, in conjunction with the consortium arrangements in respect of our Canadian timber operations and our South American electricity transmission operations, we pay to Brookfield our pro-rata share of base management fees paid by each of the respective consortiums and, in the case of our Canadian timber operations, our pro-rata share of performance fees. Pursuant to the Master Services Agreement, the base management fees paid pursuant to the consortium arrangements are creditable against the management fee payable under the Master Services Agreement and, in the case of the performance fees paid pursuant to the consortium arrangements in respect of the Canadian timber operations, such performance fees reduce incentive distributions to which Brookfield would otherwise be entitled from the Holding LP pursuant to the Holding LP's limited partnership agreement. See Item 6.A "Directors and Senior Management—Our Master Services Agreement."

In addition, until June 30, 2009 operations, maintenance and corporate services were provided to our North American electricity transmission operations by Brookfield on an outsourced—cost recovery basis, with such costs being recoverable under the regulated revenue requirement of this operation.

Pursuant to our limited partnership agreement, the Managing General Partner is entitled to receive a general partner distribution equal to 0.01% of the total distributions of our partnership. See Item 10.B "Memorandum and Articles of Association—Description of Our Units and Our Limited Partnership Agreement."

Pursuant to the limited partnership agreement of the Holding LP, the Infrastructure GP LP is entitled to receive a general partner distribution from the Holding LP equal to a share of the total distributions of the Holding LP in proportion to the Infrastructure GP LP's percentage interest in the Holding LP which, immediately following the spin-off, was equal to 1% of the total distributions of the Holding LP. See Item 10.B "Memorandum and Articles of Association—Description of the Holding LP's Limited Partnership Agreement—Distributions." In addition, it is entitled to receive the incentive distributions described above under "—Incentive Distribution."

The Holding LP has a distribution reinvestment plan. Brookfield has advised our partnership that it may from time-to-time reinvest distributions it receives from the Holding LP in the Holding LP's distribution reinvestment plan. In addition, our partnership adopted a distribution reinvestment plan which became effective on June 29, 2010. The following is a summary description of the principal terms of our partnership's distribution reinvestment plan.

Pursuant to the distribution reinvestment plan, holders of our units may elect to have distributions paid on our units held by them automatically reinvested in additional units to be held for the account of the unitholder in accordance with the terms of the distribution reinvestment plan, provided that there are not any laws or governmental regulations in the unitholder's jurisdiction that may limit or prohibit participation. Distributions to be reinvested in our units under the distribution reinvestment plan will be reduced by the amount of any applicable withholding tax.

Distributions due to plan participants will be paid to the plan agent, for the benefit of the plan participants and, if a plan participant has elected to have his or her distributions automatically reinvested, applied, on behalf of such plan participant, to the purchase of additional units. Such purchases will be made from our partnership on the distribution date at a price per unit calculated by reference to the volume weighted average of the trading price for our units on the New York Stock Exchange, or NYSE, for the five trading days immediately preceding the date the relevant distribution is paid by our partnership, or the Market Price.

As soon as reasonably practicable after each distribution payment date, a statement of account will be mailed to each participant setting out the amount of the relevant cash distribution reinvested, the applicable Market Price, the number of units purchased under the distribution reinvestment plan on the distribution payment date and the total number of units, computed to four decimal places, held for the account of the participant under the distribution reinvestment plan (or, in the case of DTC participants, DTC will receive such statement on behalf of beneficial owners participating in the distribution reinvestment plan). While our partnership will not issue fractional units, a plan participant's entitlement to units purchased under the distribution reinvestment plan may include a fraction of a unit and such fractional units shall accumulate. A cash adjustment for any fractional units will be paid by the plan agent upon the withdrawal from or termination by a plan participant of his or her participation in the distribution reinvestment plan or upon termination of the distribution reinvestment plan at price per unit calculated based upon the closing price of our units on the NYSE on the trading day immediately preceding such withdrawal or termination. A registered holder may, at any time, obtain unit certificates for any number of whole units held for the participant's account under the distribution reinvestment plan by notifying the plan agent. Certificates for units acquired under the distribution reinvestment plan will not be issued to participants unless specifically requested. Prior to pledging, selling or otherwise transferring units held for a participant's account (except for sale of units through the plan agent), a registered holder must request that his or her units be electronically transferred to his or her brokerage account or a unit certificate be issued. The automatic reinvestment of distributions under the distribution reinvestment plan will not relieve participants of any income tax obligations applicable to such distributions. No brokerage commissions will be payable in connection with the purchase of our units under the distribution reinvestment plan and all administrative costs will be borne by our partnership.

Unitholders will be able to terminate their participation in the distribution reinvestment plan by providing, or by causing to be provided, notice to the plan agent. Such notice, if actually received by the plan agent no later than 5 business days prior to a record date, will have effect in respect of the distribution to be made as of such date. Thereafter, distributions to such unitholders will be in cash. In addition, unitholders may request that all or part of their units be sold. When units are sold through the plan agent, a holder will receive the proceeds less a handling charge and any brokerage trading fees. Our partnership will be able to terminate the distribution reinvestment plan, in its sole discretion, upon notice to the plan participants and the plan agent, but such action will have no retroactive effect that would prejudice a participant's interest. Our partnership will also be able to amend, modify or suspend the distribution reinvestment plan at any time in its sole discretion, provided that the plan agent gives written notice of that amendment, modification or suspension to our unitholders, for any amendment, modification or suspension to the distribution reinvestment plan that in our partnership's opinion may materially prejudice participants.

Our partnership does not intend to reinvest distributions it receives from the Holding LP in the Holding LP's distribution reinvestment plan except to the extent that holders of our units elect to reinvest distributions pursuant to our distribution reinvestment plan. Brookfield has advised our partnership that it may from time-to-time reinvest distributions it receives from the Holding LP pursuant to the Holding LP's distribution reinvestment plan. The units of the Holding LP to be issued to Brookfield under the distribution reinvestment plan will become subject to the Redemption-Exchange Mechanism and may therefore result in Brookfield acquiring additional units of our partnership. See Item 10.B "Memorandum and Articles of Association—Description of the Holding LP's Limited Partnership Agreement—Redemption-Exchange Mechanism."

Our partnership suspended its distribution reinvestment plan for the quarters ended December 31, 2010 and March 31, 2011 pending the filing of required financial information relating to the acquisition of Prime on December 8, 2010. We anticipate that the suspension of our partnership's distribution reinvestment plan will apply only for the quarters ended December 31, 2010 and March 31, 2011 and

expect to resume making distributions of our units pursuant to the distribution reinvestment plan for the quarter ending June 30, 2011.

Subject to certain limitations, Brookfield and its directors, officers, agents, members, partners, shareholders and employees generally benefit from indemnification provisions and limitations on liability that are included in our limited partnership agreement, our Managing General Partner's By-laws, the Holding LP's limited partnership agreement, our Master Services Agreement and other arrangements with Brookfield. See Item 6.A "Directors and Senior Management—Our Master Services Agreement," Item 10.B "Memorandum and Articles of Association—Description of Our Units and Our Limited Partnership Agreement—Indemnification; Limitations of Liability" and Item 10.B "Memorandum and Articles of Association—Description of the Holding LP's Limited Partnership Agreement—Indemnification; Limitations of Liability."

Our partnership and the Holding LP have each entered into a licensing agreement with Brookfield pursuant to which Brookfield has granted a non-exclusive, royalty-free license to use the name "Brookfield" and the Brookfield logo. Other than under this limited license, we do not have a legal right to the "Brookfield" name and the Brookfield logo in the United States and Canada.

We will be permitted to terminate the licensing agreement upon 30 days' prior written notice if Brookfield defaults in the performance of any material term, condition or agreement contained in the agreement and the default continues for a period of 30 days after written notice of termination of the breach is given to Brookfield. Brookfield may terminate the licensing agreement effective immediately upon termination of our Master Services Agreement or with respect to any licensee upon 30 days' prior written notice of termination if any of the following occurs:

A termination of the licensing agreement with respect to one or more licensee will not affect the validity or enforceability of the agreement with respect to any other licensees.

Our organizational and ownership structure and strategy involve a number of relationships that may give rise to conflicts of interest between our partnership and our unitholders, on the one hand, and Brookfield, on the other hand. In particular, conflicts of interest could arise, among other reasons, because:

With respect to transactions in which there is greater potential for a conflict of interest to arise, our Managing General Partner may be required to seek the prior approval of a majority of the independent directors pursuant to conflict of interest guidelines that have been approved by a majority of the independent directors. These transactions include (i) the dissolution of our partnership; (ii) any material amendment to the Master Services Agreement, our limited partnership agreement or the Holding LP's limited partnership agreement; (iii) any material service agreement or other arrangement pursuant to which Brookfield will be paid a fee, or other consideration other than any agreement or arrangement contemplated by the Master Services Agreement; (iv) acquisitions by us from, and dispositions by us to, Brookfield; (v) any other transaction involving Brookfield; and (vi) termination of, or any determinations regarding indemnification under, the Master Services Agreement. Pursuant to our conflicts policy, independent directors may grant prior approvals for any of these transactions in

the form of general guidelines, policies or procedures in which case no further special approval will be required in connection with a particular transaction or matter permitted thereby. In certain circumstances, these transactions may be related party transactions for the purposes of, and subject to certain requirements of Multilateral Instrument 61-101—Protection of Minority Security Holders in Special Transactions, or MI 61-101, which in some situations requires minority shareholder approval and/or valuation for transactions with related parties. An exemption from such requirements is available when the fair market value of the transaction is not more than 25% of the market capitalization of the issuer. Our partnership has been granted exemptive relief from the requirements of MI 61-101 that, subject to certain conditions, would permit it to be exempt from the minority approval and valuation requirements for transactions that would have a value of less than 25% of our partnership's market capitalization if Brookfield's indirect equity interest in our partnership was included in the calculation of our partnership's market capitalization. As a result, the 25% threshold above which the minority approval and valuation requirements would apply would be increased to include the approximately 40% indirect interest in our partnership held by Brookfield.

We maintain a conflicts policy to assist in the resolution of these potential or actual conflicts which states that conflicts be resolved based on the principles of transparency, independent validation and approvals. The policy recognizes the benefit to us of our relationship with Brookfield and our intent to pursue a strategy that seeks to maximize the benefits from this relationship. The policy also recognizes that the principal areas of potential application of the policy on an ongoing basis will be in connection with our acquisitions and our participation in Brookfield led consortia and partnership arrangements, together with any management or service arrangements entered into in connection therewith or the ongoing operations of the underlying operating entities.

In general, the policy provides that acquisitions that are carried out jointly by us and Brookfield, or in the context of a Brookfield led or co-led consortium or partnership be carried out on the basis that the consideration paid by us be no more, on a per share or proportionate basis, than the consideration paid by Brookfield or other participants, as applicable. The policy also provides that any fees or carried interest payable in respect of our proportionate investment, or in respect of an acquisition made solely by us, must be credited in the manner contemplated by our Master Services Agreement and the Holding LP's limited partnership agreement, where applicable, or that such fees or carried interest must either have been negotiated with another arm's length participant or otherwise demonstrated to be on market terms. The policy further provides that if the acquisition involves the purchase by us of an asset from Brookfield, or the participation in a transaction involving the purchase by us and Brookfield of different assets, that a fairness opinion or, in some circumstances, a valuation or appraisal by a qualified expert be obtained. These requirements provided for in the conflicts policy are in addition to any disclosure, approval and valuation requirements that may arise under applicable law.

Our limited partnership agreement and the limited partnership agreement of the Holding LP contain various provisions that modify the fiduciary duties that might otherwise be owed to us and our unitholders. These duties include the duties of care and loyalty. The duty of loyalty, in the absence of provisions in the limited partnership agreements of our partnership and the Holding LP to the contrary, would generally prohibit the Managing General Partner and Infrastructure General Partner from taking any action or engaging in any transaction as to which it has a conflict of interest. The limited partnership agreements of our partnership and the Holding LP each prohibit the limited partners from advancing claims that otherwise might raise issues as to compliance with fiduciary duties or applicable law. For example, the agreements provide that our Managing General Partner, the Infrastructure General Partner and their affiliates will not have any obligation under the limited partnership agreements of our partnership or the Holding LP, 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 vehicle established by our

partnership. They also allow affiliates of the Managing General Partner and Infrastructure General Partner to engage in activities that may compete with us or our activities. In addition, the agreements permit our Managing General Partner and the Infrastructure General Partner to take into account the interests of third parties, including Brookfield, when resolving conflicts of interest.

These modifications to the fiduciary duties are detrimental to our 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 always in the best interests of our partnership or the best interests of our unitholders. We believe it is necessary to modify the fiduciary duties that might otherwise be owed to us and our unitholders, as described above, due to our organizational and ownership structure and the potential conflicts of interest created thereby. Without modifying those duties, the ability of our Managing General Partner and the Infrastructure General Partner to attract and retain experienced and capable directors and to take actions that we believe will be necessary for the carrying out of our business would be unduly limited due to their concern about potential liability.

The following is a description of the material terms of our units and our limited partnership agreement, as amended, and is qualified in its entirety by reference to all of the provisions of our limited partnership agreement. Because this description is only a summary of the terms of our units and our limited partnership agreement, it does not contain all of the information that you may find useful. For more complete information, you should read the limited partnership agreement which is available electronically on the website of the Securities and Exchange Commission at www.sec.gov and our SEDAR profile at www.sedar.com and will be made available to our holders as described under Item 10.C "Material Contracts" and Item 10.H "Documents on display."

See also the information contained in this annual report on Form 20-F under Item 3.D "Risk Factors—Risk Relating to Our Relationship with Brookfield," Item 6.C "Board Practices," Item 6.A "Directors and Senior Management" and Item 7.B "Related Party Transactions."

Our partnership is a Bermuda exempted limited partnership registered under the Limited Partnership Act 1883 and the Exempted Partnerships Act 1992. Our partnership has a perpetual existence and will continue as a limited liability partnership unless our partnership is terminated or dissolved in accordance with our limited partnership agreement. Our partnership interests consist of our units, which represent limited partnership interests in our partnership, and any additional partnership interests representing limited partnership interests that we may issue in the future as described below under "—Issuance of Additional Partnership Interests." In this description, references to "holders of our partnership interests" and our "unitholders" are to our limited partners and references to our limited partners include holders of our units.

Under section 2.2 of our limited partnership agreement, the purpose of our partnership is to: acquire and hold interests in the Holding LP and, subject to the approval of the Managing General Partner, any other subsidiary of our partnership; engage in any activity related to the capitalization and financing of our partnership's interests in such entities; and engage in any other activity that is incidental to or in furtherance of the foregoing and that is approved by our Managing General Partner and that lawfully may be conducted by a limited partnership organized under the Limited Partnership Act 1883 and our limited partnership agreement.

Our units are limited partnership interests in our partnership. Holders of our units are not entitled to the withdrawal or return of capital contributions in respect of our units, except to the extent, if any, that distributions are made to such holders pursuant to our limited partnership agreement or upon the liquidation of our partnership as described below under "—Liquidation and Distribution of Proceeds" or as otherwise required by applicable law. Except to the extent expressly provided in our limited partnership agreement, a holder of our units does not have priority over any other holder of our units, either as to the return of capital contributions or as to profits, losses or distributions. Holders of our units will not be granted any preemptive or other similar right to acquire additional interests in our partnership. In addition, holders of our units do not have any right to have their units redeemed by our partnership.

Our Managing General Partner has broad rights to cause our partnership to issue additional partnership interests and may cause our partnership to issue additional partnership interests (including new classes of partnership interests and options, rights, warrants and appreciation rights relating to such interests) for any partnership purpose, at any time and on such terms and conditions as it may determine without the approval of any limited partners. Any additional partnership interests may be issued in one or more classes, or one or more series of classes, with such designations, preferences, rights, powers and duties (which may be senior to existing classes and series of partnership interests) as may be determined by our Managing General Partner in its sole discretion, all without approval of our limited partners.

If and to the extent that our partnership raises funds by way of the issuance of equity or debt securities, or otherwise, pursuant to a public offering, private placement or otherwise, an amount equal to the proceeds will be invested in the Holding LP.

Brookfield and the Managing General Partner each contributed $1 to the capital of our partnership in order to form our partnership. Thereafter, Brookfield contributed to our partnership limited partnership interests of the Holding LP in exchange for Redeemable Partnership Units and our units, the latter of which was distributed by Brookfield Asset Management in the spin off.

Distributions to partners of our partnership will be made only as determined by the Managing General Partner in its sole discretion. However, the Managing General Partner will not be permitted to cause our partnership to make a distribution if it does not have sufficient cash on hand to make the distribution, the distribution would render it insolvent or if, in the opinion of the Managing General Partner, the distribution would leave it with insufficient funds to meet any future contingent obligations.

Any distributions from our partnership will be made to the limited partners as to 99.99% and to the Managing General Partner as to 0.01%. Each limited partner will receive a pro rata share of distributions made to all limited partners in accordance with the proportion of all outstanding units held by that limited partner. See Item 8.A "Consolidated Statements and Other Financial Information."

Net income and net loss for U.S. federal income tax purposes will be allocated for each taxable year among our partners using a monthly, quarterly or other permissible convention pro rata on a per unit basis, except to the extent otherwise required by law or pursuant to tax elections made by our partnership. The source and character of items of income and loss so allocated to a partner of our partnership will be the same source and character as the income earned or loss incurred by our partnership.

The income for Canadian federal income tax purposes of our partnership for a given fiscal year of our partnership will be allocated to each partner in an amount calculated by multiplying such income by a fraction, the numerator of which is the sum of the distributions received by such partner with respect to such fiscal year and the denominator of which is the aggregate amount of the distributions made by our partnership to partners with respect to such fiscal year. Generally, the source and character of items of income so allocated to a partner with respect to a fiscal year of our partnership will be the same source and character as the distributions received by such partner with respect to such fiscal year.

If, with respect to a given fiscal year, no distribution is made by our partnership or our partnership has a loss for Canadian federal income tax purposes, one quarter of the income, or loss, as the case may be, for Canadian federal income tax purposes of our partnership for such fiscal year, will be allocated to the partners of record at the end of each calendar quarter ending in such fiscal year pro rata to their respective percentage interests in our partnership, which in the case of the Managing General Partner shall mean 0.01%, and in the case of all limited partners of our partnership shall mean in the aggregate 99.99%, which aggregate percentage interest shall be allocated among the limited partners in the proportion that the number of limited partnership units held at each such date by a limited partner is of the total number of limited partnership units issued and outstanding at each such date. Generally, the source and character of such income or losses so allocated to a partner at the end of each calendar quarter will be the same source and character as the income or loss earned or incurred by our partnership in such calendar quarter.

Assuming that a limited partner does not participate in the control or management of our partnership or conduct the affairs of, sign or execute documents for or otherwise bind our partnership within the meaning of the Limited Partnership Act 1883 and otherwise acts in conformity with the provisions of our limited partnership agreement, such partner's liability under the Limited Partnership Act 1883 and our limited partnership agreement will be limited to the amount of capital such partner is obligated to contribute to our partnership for its limited partner interest plus its share of any undistributed profits and assets, except as described below.

If it were determined, however, that a limited partner was participating in the control or management of our partnership or conducting the affairs of, signing or executing documents for or otherwise binding our partnership (or purporting to do any of the foregoing) within the meaning of the Limited Partnership Act 1883 or the Exempted Partnerships Act 1992, such limited partner would be liable as if it were a general partner of our partnership in respect of all debts of our partnership incurred while that limited partner was so acting or purporting to act. Neither our limited partnership agreement nor the Limited Partnership Act 1883 specifically provides for legal recourse against our Managing General Partner if a limited partner were to lose limited liability through any fault of our Managing General Partner. While this does not mean that a limited partner could not seek legal recourse, we are not aware of any precedent for such a claim in Bermuda case law.

Our partnership's limited partners, in their capacities as such, may not take part in the management or control of the activities and affairs of our partnership and do not have any right or authority to act for or to bind our partnership or to take part or interfere in the conduct or management of our partnership. Limited partners are not entitled to vote on matters relating to our partnership, although holders of units are entitled to consent to certain matters as described under "—Amendment of Our Limited Partnership Agreement," "—Opinion of Counsel and Limited Partner Approval," "—Merger, Sale or Other Disposition of Assets," and "—Withdrawal of Our Managing General Partner" which may be effected only with the consent of the holders of the percentages of our outstanding units specified below. Each unit shall entitle the holder thereof to one vote for the purposes of any approvals of holders of units.

Our Managing General Partner may call special meetings of partners at a time and place outside of Canada determined by our Managing General Partner on a date not less than 10 days nor more than 60 days after the mailing of notice of the meeting. The limited partners do not have the ability to call a special meeting. Only holders of record on the date set by our Managing General Partner (which may not be less than 10 days nor more than 60 days, before the meeting) are entitled to notice of any meeting.

Written consents may be solicited only by or on behalf of our Managing General Partner. Any such consent solicitation may specify that any written consents must be returned to our partnership within the time period, which may not be less than 20 days, specified by our Managing General Partner.

For purposes of determining holders of partnership interests entitled to provide consents to any action described above, our Managing General Partner may set a record date, which may be not less than 10 nor more than 60 days before the date by which record holders are requested in writing by our Managing General Partner to provide such consents. Only those holders of partnership interests on the record date established by our Managing General Partner will be entitled to provide consents with respect to matters as to which a consent right applies.

Amendments to our limited partnership agreement may be proposed only by or with the consent of our Managing General Partner. To adopt a proposed amendment, other than the amendments that do not require limited partner approval discussed below, our Managing General Partner must seek approval of a majority of our outstanding units required to approve the amendment or call a meeting of the limited partners to consider and vote upon the proposed amendment.

The provision of our limited partnership agreement preventing the amendments having the effects described directly above can be amended upon the approval of the holders of at least 90% of the outstanding units.

Subject to applicable law, our Managing General Partner may generally make amendments to our limited partnership agreement without the approval of any limited partner to reflect:

In addition, our Managing General Partner may make amendments to our limited partnership agreement without the approval of any limited partner if those amendments, in the discretion of our Managing General Partner:

Our Managing General Partner will not be required to obtain an opinion of counsel that an amendment will not result in a loss of limited liability to the limited partners if one of the amendments described above under "—No Limited Partner Approval" should occur. No other amendments to our limited partnership agreement (other than an amendment pursuant to a merger, sale or other disposition of assets effected in accordance with the provisions described under "—Merger, Sale or Other Disposition of Assets") will become effective without the approval of holders of at least 90% of our units, unless our partnership obtains an opinion of counsel to the effect that the amendment will not cause our partnership to be treated as an association taxable as a corporation or otherwise taxable as an entity for tax purposes (provided that for U.S. tax purposes our Managing General Partner has not made the election described below under "—Election to be Treated as a Corporation") or affect the limited liability under the Limited Partnership Act of 1883 of any of our partnership's limited partners.

partnership interests will also require the approval of the holders of at least a majority of the outstanding partnership interests of the class so affected.

In addition, any amendment that reduces the voting percentage required to take any action must be approved by the affirmative vote of limited partners whose aggregate outstanding voting units constitute not less than the voting requirement sought to be reduced.

Any merger, consolidation or other combination of our partnership requires the prior approval of our Managing General Partner who has no duty or obligation to provide any such approval. Our limited partnership agreement generally prohibits our Managing General Partner, without the prior approval of the holders of a majority of our units, from causing our partnership to, among other things, sell, exchange or otherwise dispose of all or substantially all of our partnership's assets in a single transaction or a series of related transactions, including by way of merger, consolidation or other combination, or approving on our partnership's behalf the sale, exchange or other disposition of all or substantially all of the assets of our partnership's subsidiaries. However, our Managing General Partner in its sole discretion may mortgage, pledge, hypothecate or grant a security interest in all or substantially all of our partnership's assets (including for the benefit of persons other than our partnership or our partnership's subsidiaries) without that approval. Our Managing General Partner may also sell all or substantially all of our partnership's assets under any forced sale of any or all of our partnership's assets pursuant to the foreclosure or other realization upon those encumbrances without that approval.

If conditions specified in our limited partnership agreement are satisfied, our Managing General Partner may convert or merge our partnership into, or convey some or all of our partnership's assets to, a newly formed entity if the sole purpose of that merger or conveyance is to effect a mere change in our partnership's legal form into another limited liability entity. Holders of partnership interests are not entitled to dissenters' rights of appraisal under our limited partnership agreement or the Limited Partnership Act 1883 or the Exempted Partnerships Act 1992 in the event of a merger or consolidation, a sale of substantially all of our assets or any other transaction or event.

If our Managing General Partner determines that it is no longer in our partnership's best interests to continue as a partnership for U.S. federal income tax purposes, our Managing General Partner may elect to treat our partnership as an association or as a publicly traded partnership taxable as a corporation for U.S. federal (and applicable state) income tax purposes.

Our partnership will terminate upon the earlier to occur of (i) the date on which all of our partnership's assets have been disposed of or otherwise realized by our partnership and the proceeds of such disposals or realizations have been distributed to partners, (ii) the service of notice by our Managing General Partner, with the special approval of a majority of its independent directors, that in its opinion the coming into force of any law, regulation or binding authority has or will render illegal or impracticable the continuation of our partnership, and (iii) at the election of our Managing General Partner, if our partnership, as determined by the Managing General Partner, is required to register as an "investment company" under the Investment Company Act or similar legislation in other jurisdictions.

Our partnership will be dissolved upon the withdrawal of our Managing General Partner as the general partner of our partnership (unless Brookfield becomes the general partner as described in the following sentence or the withdrawal is effected in compliance with the provisions of our limited

partnership agreement that are described below under "—Withdrawal of Our Managing General Partner") or the entry by a court of competent jurisdiction of a decree of judicial dissolution of our partnership or an order to wind up or liquidate our Managing General Partner. Our partnership will be reconstituted and continue without dissolution if within 30 days of the date of dissolution (and so long as a notice of dissolution has not been filed with the Bermuda Monetary Authority), Brookfield executes a transfer deed pursuant to which it becomes the general partner and assumes the rights and undertakes the obligations of the general partner and our partnership receives an opinion of counsel that the admission of Brookfield as general partner will not result in the loss of the limited liability of any limited partner.

Upon our dissolution, unless our partnership is continued as a new limited partnership, the liquidator authorized to wind up our partnership's affairs will, acting with all of the powers of our Managing General Partner that the liquidator deems necessary or appropriate in its judgment, liquidate our partnership's assets and apply the proceeds of the liquidation first, to discharge our partnership's liabilities as provided in our limited partnership agreement and by law and thereafter to the partners pro rata according to the percentages of their respective partnership interests as of a record date selected by the liquidator. The liquidator may defer liquidation of our partnership's assets for a reasonable period of time or distribute assets to partners in kind if it determines that an immediate sale or distribution of all or some of our partnership's assets would be impractical or would cause undue loss to the partners.

Our Managing General Partner may withdraw as Managing General Partner without first obtaining approval of our unitholders by giving 90 days' advance notice, and that withdrawal will not constitute a violation of our limited partnership agreement.

Upon the withdrawal of our Managing General Partner, the holders of a majority of the voting power of our outstanding units may select a successor to that withdrawing Managing General Partner. If a successor is not elected, or is elected but an opinion of counsel regarding limited liability, tax matters and the Investment Company Act (and similar legislation in other jurisdictions) cannot be obtained, our partnership will be dissolved, wound up and liquidated. See "—Termination and Dissolution" above.

In the event of withdrawal of a general partner where that withdrawal violates our limited partnership agreement, a successor general partner will have the option to purchase the general partnership interest of the departing general partner for a cash payment equal to its fair market value. Under all other circumstances where a general partner withdraws, the departing general partner will have the option to require the successor general partner to purchase the general partnership interest of the departing general partner for a cash payment equal to its fair market value. In each case, this fair market value will be determined by agreement between the departing general partner and the successor general partner. If no agreement is reached within 30 days of the general partner's departure, an independent investment banking firm or other independent expert selected by the departing general partner and the successor general partner will determine the fair market value. If the departing general partner and the successor general partner cannot agree upon an expert within 45 days of the general partner's departure, then an expert chosen by agreement of the experts selected by each of them will determine the fair market value.

investment banking firm or other independent expert selected in the manner described in the preceding paragraph.

Our Managing General Partner may transfer all or any part of its general partnership interests without first obtaining approval of any unitholder. As a condition of this transfer, the transferee must assume the rights and duties of the Managing General Partner to whose interest that transferee has succeeded, agree to be bound by the provisions of our limited partnership agreement and furnish an opinion of counsel regarding limited liability, tax matters, and the Investment Company Act (and similar legislation in other jurisdictions). Any transfer of the general partnership interest is subject to prior notice to and approval of the relevant Bermuda regulatory authorities. At any time, the members of our Managing General Partner may sell or transfer all or part of their shares in our Managing General Partner without the approval of the unitholders.

If our Managing General Partner ceases to be the general partner of our partnership and our new general partner is not an affiliate of Brookfield, our partnership will be required by our limited partnership agreement to change the name of our partnership to a name that does not include "Brookfield" and which could not be capable of confusion in any way with such name. Our limited partnership agreement explicitly provides that this obligation shall be enforceable and waivable by our Managing General Partner notwithstanding that it may have ceased to be the general partner of our partnership.

Our Managing General Partner, the Manager and their respective partners, members, shareholders, directors, officers, employees and shareholders, which we refer to as "interested parties," may become limited partners or beneficially interested in limited partners and may hold, dispose of or otherwise deal with our units with the same rights they would have if our Managing General Partner was not a party to our limited partnership agreement. An interested party will not be liable to account either to other interested parties or to our partnership, our partnership's partners or any other persons for any profits or benefits made or derived by or in connection with any such transaction.

Our limited partnership agreement permits an interested party to sell investments to, purchase assets from, vest assets in and enter into any contract, arrangement or transaction with our partnership, the Holding LP, any of the Holding Entities, any operating entity or any other holding vehicle established by our partnership and may be interested in any such contract, transaction or arrangement and shall not be liable to account either to our partnership, the Holding LP, any of the Holding Entities, any operating entity or any other holding vehicle established by our partnership or any other person in respect of any such contract, transaction or arrangement, or any benefits or profits made or derived therefrom, by virtue only of the relationship between the parties concerned, subject to any approval requirements that are contained in our conflicts policy. See Item 7.B "Related Party Transactions—Conflicts of Interest and Fiduciary Duties."

Under our limited partnership agreement, our Managing General Partner is required to maintain as its sole activity the role of general partner of our partnership. Our Managing General Partner is not permitted to engage in any activity or incur any debts or liabilities except in connection with or incidental to its performance as general partner or acquiring, owning or disposing of debt or equity

securities of the Holding LP, a Holding Entity or any other holding vehicle established by our partnership.

Our limited partnership agreement provides that each person who is entitled to be indemnified by our partnership (other than our Managing General Partner), as described below under "—Indemnification; Limitation on Liability," has the right to engage in businesses of every type and description and other activities for profit, and to engage in and possess interests in business ventures of any and every type or description, irrespective of whether (i) such activities are similar to our affairs or activities or (ii) such affairs and activities directly compete with, or disfavor or exclude, our Managing General Partner, our partnership, the Holding LP, any Holding Entity, any operating entity or any other holding vehicle established by our partnership. Such business interests, activities and engagements will be deemed not to constitute a breach of our limited partnership agreement or any duties stated or implied by law or equity, including fiduciary duties, owed to any of our Managing General Partner, our partnership, the Holding LP, any Holding Entity, any operating entity and any other holding vehicle established by our partnership (or any of their respective investors), and shall be deemed not to be a breach of our Managing General Partner's fiduciary duties or any other obligation of any type whatsoever of our Managing General Partner. None of our Managing General Partner, our partnership, the Holding LP, any Holding Entity, any operating entity, any other holding vehicle established by our partnership or any other person shall have any rights by virtue of our limited partnership agreement or the partnership relationship established thereby or otherwise in any business ventures of any person who is entitled to be indemnified by our partnership as described below under "—Indemnification; Limitation on Liability."

Our Managing General Partner and the other indemnified persons described in the preceding paragraph 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, any operating entity or any other holding vehicle established by our partnership. These provisions will not affect any obligation of an indemnified person to present business or investment opportunities to our partnership, the Holding LP, any Holding Entity, any operating entity or any other holding vehicle established by our partnership pursuant to a separate written agreement between such persons.

Any conflicts of interest and potential conflicts of interest that are approved by a majority of our Managing General Partner's independent directors from time-to-time will be deemed approved by all partners. Pursuant to our conflicts policy, independent directors may grant approvals for any of the transactions described above in the form of general guidelines, policies or procedures in which case no further special approval will be required in connection with a particular transaction or matter permitted thereby. See Item 7.B "Related Party Transactions—Conflicts of Interest and Fiduciary Duties."

Under our limited partnership agreement, our partnership is required to indemnify to the fullest extent permitted by law our Managing General Partner, our Manager and any of their respective affiliates (and their respective officers, directors, agents, shareholders, partners, members and employees), any person who serves on a governing body of the Holding LP, a Holding Entity, operating entity or any other holding vehicle established by our partnership and any other person designated by our Managing General Partner as an indemnified person, in each case, against all losses, claims, damages, liabilities, costs or expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, incurred by an indemnified person in connection with our investments and activities or by reason of their holding such positions, except to the extent that the claims, liabilities, losses, damages, costs or expenses are determined to have resulted from the indemnified person's bad faith, fraud or willful misconduct, or in the case of a criminal matter, action that the indemnified person knew to have

been unlawful. In addition, under our limited partnership agreement, (i) the liability of such persons has been limited to the fullest extent permitted by law, except to the extent that their conduct involves bad faith, fraud or willful misconduct, or in the case of a criminal matter, action that the indemnified person knew to have been unlawful and (ii) any matter that is approved by the independent directors of our Managing General Partner will not constitute a breach of our limited partnership agreement or any duties stated or implied by law or equity, including fiduciary duties. Our limited partnership agreement requires us to advance funds to pay the expenses of an indemnified person in connection with a matter in which indemnification may be sought until it is determined that the indemnified person is not entitled to indemnification.

Pursuant to an amendment to our limited partnership agreement dated February 5, 2010, our partnership is required to prepare financial statements in accordance with IFRS. This change was made in light of the Holding LP's investments in Prime, DBCT and PD Ports which use IFRS as their primary basis of accounting. The first financial statements of our partnership and the Holding LP to be prepared in accordance with IFRS were for the financial statements as at and for the quarter ended March 31, 2010. We adopted new accounting standards effective from the quarter ending March 31, 2010, and this adoption may have a material impact on our consolidated financial statements.

Our partnership's financial statements must be made publicly available together with a statement of the accounting policies used in their preparation, such information as may be required by applicable laws and regulations and such information as our Managing General Partner deems appropriate. Our partnership's annual financial statements must be audited by an independent accountant firm of international standing and made publicly available within such period of time as is required to comply with applicable laws and regulations, including any rules of any applicable securities exchange. Our partnership's quarterly financial statements may be unaudited and are made available publicly as and within the time period required by applicable laws and regulations.

The Managing General Partner is also required to use commercially reasonable efforts to prepare and send to the limited partners of our partnership on an annual basis, additional information regarding our partnership, including Schedule K-1 (or equivalent) and information related to the passive foreign investment company status of any non-U.S. corporation that we control and, where reasonably possible, any other non-U.S. corporation in which we hold an interest. The Managing General Partner will, where reasonably possible, prepare and send information required by the non-U.S. limited partners of our partnership for U.S. federal income tax reporting purposes, including information related to investments in "U.S. real property interests," as that term is defined in Section 897 of the U.S. Internal Revenue Code. The Managing General Partner will also, where reasonably possible and applicable, prepare and send information required by limited partners of our partnership for Canadian federal income tax purposes.

Our limited partnership agreement is governed by and will be construed in accordance with the laws of Bermuda. Under our limited partnership agreement, each of our partnership's partners (other than governmental entities prohibited from submitting to the jurisdiction of a particular jurisdiction) will submit to the non-exclusive jurisdiction of any court in Bermuda in any dispute, suit, action or proceeding arising out of or relating to our limited partnership agreement. Each partner waives, to the fullest extent permitted by law, any immunity from jurisdiction of any such court or from any legal process therein and further waives, to the fullest extent permitted by law, any claim of inconvenient forum, improper venue or that any such court does not have jurisdiction over the partner. Any final judgment against a partner in any proceedings brought in a court in Bermuda will be conclusive and binding upon the partner and may be enforced in the courts of any other jurisdiction of which the

partner is or may be subject, by suit upon such judgment. The foregoing submission to jurisdiction and waivers will survive the dissolution, liquidation, winding up and termination of our partnership.

We are not required to recognize any transfer of our units until certificates, if any, evidencing such units are surrendered for registration of transfer. Each person to whom a unit is transferred (including any nominee holder or an agent or representative acquiring such unit for the account of another person) will be admitted to our partnership as a partner with respect to the unit so transferred subject to and in accordance with the terms of our limited partnership agreement. Any transfer of a unit will not entitle the transferee to share in the profits and losses of our partnership, to receive distributions, to receive allocations of income, gain, loss, deduction or credit or any similar item or to any other rights to which the transferor was entitled until the transferee becomes a partner and a party to our partnership's limited partnership agreement.

By accepting a unit for transfer in accordance with our limited partnership agreement, each transferee will be deemed to have:

The transfer of any unit and the admission of any new partner to our partnership will not constitute any amendment to our limited partnership agreement.

The Bank of New York in New York, New York, U.S.A. has been appointed to act as transfer agent and registrar for the purpose of registering our limited partnership interests and transfers of our limited partnership interests as provided in our limited partnership agreement. Our partnership will indemnify the transfer agent, its agents and each of their shareholders, directors, officers and employees against all claims and losses that may arise out of acts performed or omitted for its activities

in that capacity, except for any liability due to any gross negligence or intentional misconduct of the indemnified person or entity.

The following is a description of the material terms of the Holding LP's limited partnership agreement and is qualified in its entirety by reference to all of the provisions of such agreement. Holders of units in our partnership are not limited partners of the Holding LP and do not have any rights under its limited partnership agreement. Pursuant to the Voting Agreements, however, our partnership, through our Managing General Partner, has the right to direct all eligible votes in the election of the directors of the Infrastructure General Partner, through which our partnership participates in the management and activities of the Holding LP and the Holding Entities. See Item 7.B "Related Party Transactions—Voting Agreements".

Because this description is only a summary of the terms of the agreement, it does not necessarily contain all of the information that you may find useful. For more complete information, you should read the Holding LP's limited partnership agreement which is available electronically on the website of the Securities and Exchange Commission at www.sec.gov and on our SEDAR profile at www.sedar.com and will be made available to our unitholders as described under Item 10.C "Material Contracts" and Item 10.H "Documents on display."

The Holding LP is a Bermuda exempted limited partnership registered under the Limited Partnership Act 1883 and the Exempted Partnerships Act 1992. The Holding LP has a perpetual existence and will continue as a limited liability partnership unless the partnership is terminated or dissolved in accordance with its limited partnership agreement.

Under its limited partnership agreement, the purpose of the Holding LP is to: acquire and hold interests in the Holding Entities and, subject to the approval of Infrastructure GP LP, any other subsidiary of the Holding LP; engage in any activity related to the capitalization and financing of the Holding LP's interests in such entities; and engage in any other activity that is incidental to or in furtherance of the foregoing and that is approved by the Infrastructure GP LP and that lawfully may be conducted by a limited partnership organized under the Limited Partnership Act 1883 and our limited partnership agreement.

The Holding LP's units are limited partnership interests in the Holding LP. Holders of units are not entitled to the withdrawal or return of capital contributions in respect of their units, except to the extent, if any, that distributions are made to such holders pursuant to the Holding LP's limited partnership agreement or upon the liquidation of the Holding LP or as otherwise required by applicable law. Except to the extent expressly provided in the Holding LP's limited partnership agreement, a holder of units does not have priority over any other holder of units, either as to the return of capital contributions or as to profits, losses or distributions.

In connection with the spin-off, the Holding LP issued two classes of units. The first class of units was issued to Brookfield and subsequently transferred to our partnership and the second class of units, referred to as the Redeemable Partnership Units, were issued to wholly-owned subsidiaries of Brookfield. Redeemable Partnership Units are identical to the limited partnership units held by our partnership, except as described below under "—Distributions" and "—No Management or Control"

and except that they have the right of redemption described below under the heading "—Redemption-Exchange Mechanism."

The Holding LP may issue additional partnership interests (including new classes of partnership interests and options, rights, warrants and appreciation rights relating to such interests) for any partnership purpose, at any time and on such terms and conditions as its general partner may determine. Any additional partnership interests may be issued in one or more classes, or one or more series of classes, with such designations, preferences, rights, powers and duties (which may be senior to existing classes and series of partnership interests) as its general partner may determine in its sole discretion.

At any time, one or more wholly-owned subsidiaries of Brookfield that hold Redeemable Partnership Units will have the right to require the Holding LP to redeem for cash all or a portion of the Redeemable Partnership Units held by such subsidiary, subject to our partnership's right of first refusal, as described below. Any such redeeming subsidiary may exercise its right of redemption by delivering a notice of redemption to the Holding LP and our partnership. After presentation for redemption, such redeeming subsidiary will receive, subject to our partnership's right of first refusal, as described below, for each unit that is presented, cash in an amount equal to the market value of one of our units multiplied by the number of units to be redeemed (as determined by reference to the five day volume weighted average of the trading price of our units and subject to certain customary adjustments). Upon its receipt of the redemption notice, our partnership will have a right of first refusal entitling it, at its sole discretion, to elect to acquire all (but not less than all) units described in such notice and presented to the Holding LP for redemption in exchange for units on a one for one basis (subject to certain customary adjustments). Upon a redemption for cash, the holder's right to receive distributions with respect to the Holding LP's units so redeemed will cease.

Brookfield's aggregate limited partnership interest in our partnership would be approximately 29% if it exercised its redemption right in full and our partnership exercised its right of first refusal on the Holding LP's units redeemed. Brookfield's total percentage interest in our partnership would be increased if it participates in the Holding LP's distribution reinvestment plan.

Distributions by the Holding LP will be made in the sole discretion of its general partner. However, its general partner will not be permitted to cause the Holding LP to make a distribution if the Holding LP does not have sufficient cash on hand to make the distribution, the distribution would render the Holding LP insolvent or if, in the opinion of its general partner, the distribution would leave the Holding LP with insufficient funds to meet any future contingent obligations.

Except as set forth below, prior to the dissolution of the Holding LP, distributions of available cash (if any) in any given quarter will be made by the Holding LP as follows, referred to as the Regular Distribution Waterfall:

If, prior to the dissolution of the Holding LP, available cash is deemed by its general partner, in its sole discretion, to be (i) attributable to sales or other dispositions of the Holding LP's assets and (ii) representative of unrecovered capital, then such available cash shall be distributed to the partners of the Holding LP in proportion to the unreturned capital attributable to the Holding LP's partnership interests held by the partners until such time as the unreturned capital attributable to each such partnership interest is equal to zero. Thereafter, distributions of available cash made by the Holding LP (to the extent made prior to dissolution) will be made in accordance with the Regular Distribution Waterfall.

Upon the occurrence of an event resulting in the dissolution of the Holding LP, all cash and property of the Holding LP in excess of that required to discharge the Holding LP's liabilities will be distributed as follows: (i) to the extent such cash and/or property is attributable to a realization event occurring prior to the event of dissolution, such cash and/or property will be distributed in accordance with the Regular Distribution Waterfall and/or the distribution waterfall applicable to unrecovered capital; and (ii) all other cash and/or property will be distributed in the manner set forth below.

Each partner's percentage interest is determined by the relative portion of all outstanding partnership interests held by that partner from time to time and is adjusted upon and to reflect the issuance of additional partnership interests of the Holding LP. In addition, the unreturned capital attributable to each of the partnership interests, as well as certain of the distribution thresholds set forth above, may be adjusted pursuant to the terms of the limited partnership agreement of the Holding LP so as to ensure the uniformity of the economic rights and entitlements of (i) the previously outstanding partnership interests of the Holding LP, and (ii) the subsequently- issued partnership interests of the Holding LP.

The limited partnership agreement of the Holding LP provides that, to the extent that any Holding Entity or any operating entity pays to Brookfield any comparable performance or incentive distribution, the amount of any incentive distributions paid to the Infrastructure GP LP in accordance with the distribution entitlements described above will be reduced in an equitable manner to avoid duplication of distributions.

The Infrastructure GP LP may elect, at its sole discretion, to reinvest incentive distributions in Redeemable Partnership Units.

The Holding LP's limited partners, in their capacities as such, may not take part in the management or control of the activities and affairs of the Holding LP and do not have any right or authority to act for or to bind the Holding LP or to take part or interfere in the conduct or management of the Holding LP.

Limited partners are not entitled to vote on matters relating to the Holding LP, although holders of units are entitled to consent to certain matters as described under "—Amendment of the Holding LP's Limited Partnership Agreement," "—Opinion of Counsel and Limited Partner Approval," "—Merger, Sale or Other Disposition of Assets," and "—Withdrawal of the General Partner" which may be effected only with the consent of the holders of the percentages of outstanding units specified below. For the purposes of any approval required from holders of the Holding LP's units, if Brookfield and its subsidiaries are entitled to vote, they will be entitled to one vote per unit held subject to a maximum number of votes equal to 49% of the total number of units of the Holding LP then issued and outstanding. Each unit shall entitle the holder thereof to one vote for the purposes of any approvals of holders of units.

In addition, pursuant to the Voting Agreements, our partnership, through our Managing General Partner, has the right to direct all eligible votes in the election of the directors of the Infrastructure General Partner, through which our partnership participates in the management and activities of the Holding LP and the Holding Entities. See Item 7.B "Related Party Transactions—Voting Agreements".

Special meetings of the limited partners of the Holding LP may be called by its general partner at a time and place outside of Canada determined by it on a date not less than 10 days nor more than 60 days after the mailing of notice of the meeting. Special meetings of the limited partners may also be called by limited partners owning 50% or more of the voting power of the outstanding partnership interests of the class or classes for which a meeting is proposed. For this purpose, the partnership interests outstanding do not include partnership interests owned by its general partner or Brookfield. Only holders of partnership interests of the Holding LP of record on the date set by its general partner (which may not be less than 10 days nor more than 60 days, before the meeting) are entitled to notice of any meeting.

Amendments to the Holding LP's limited partnership agreement may be proposed only by or with the consent of its general partner. To adopt a proposed amendment, other than the amendments that do not require limited partner approval discussed below, the general partner must seek approval of a majority of the Holding LP's outstanding units required to approve the amendment or call a meeting of the limited partners to consider and vote upon the proposed amendment.

The provision of the Holding LP's limited partnership agreement preventing the amendments having the effects described directly above can be amended upon the approval of the holders of at least 90% of the outstanding units.

Subject to applicable law, the Infrastructure GP LP may generally make amendments to the Holding LP's limited partnership agreement without the approval of any limited partner to reflect:

In addition, amendments to the Holding LP's limited partnership agreement may be made by its general partner without the approval of any limited partner if those amendments, in the discretion of the general partner:

The Infrastructure GP LP will not be required to obtain an opinion of counsel that an amendment will not result in a loss of limited liability to the limited partners if one of the amendments described above under "—No Limited Partner Approval" should occur. No other amendments to the Holding LP's limited partnership agreement (other than an amendment pursuant to a merger, sale or other disposition of assets effected in accordance with the Holding LP's limited partnership agreement) will become effective without the approval of holders of at least 90% of the Holding LP's units, unless it obtains an opinion of counsel to the effect that the amendment will not cause the Holding LP to be treated as an association taxable as a corporation or otherwise taxable as an entity for tax purposes (provided that for U.S. tax purposes its general partner has not made the election described below under "—Election to be Treated as a Corporation") or affect the limited liability under the Limited Partnership Act of 1883 of any of the Holding LP's limited partners.

In addition to the above restrictions, any amendment that would have a material adverse effect on the rights or preferences of any type or class of partnership interests in relation to other classes of partnership interests will also require the approval of the holders of at least a majority of the outstanding partnership interests of the class so affected.

If, in the determination of its general partner, it is no longer in the Holding LP's best interests to continue as a partnership for U.S. federal income tax purposes, the Infrastructure GP LP may elect to treat the Holding LP as an association or as a publicly traded partnership taxable as a corporation for U.S. federal (and applicable state) income tax purposes.

The Holding LP shall dissolve and its affairs shall be wound up, upon the earlier of (i) the service of notice by its general partner, with the approval of a majority of the members of the independent directors of our Managing General Partner, that, in the opinion of the general partner, the coming into force of any law, regulation or binding authority renders illegal or impracticable the continuation of the Holding LP; (ii) the election of its general partner if the Holding LP, as determined by its general partner, is required to register as an "investment company" under the Investment Company Act or similar legislation in other jurisdictions; (iii) the date that its general partner withdraws from the partnership (unless Brookfield becomes the general partner of the Holding LP as described below under "—Withdrawal of the General Partner"); (iv) the date on which any court of competent jurisdiction enters a decree of judicial dissolution of the Holding LP or an order to wind up or liquidate its general partner; and (v) the date on which its general partner decides to dispose of, or otherwise realize proceeds in respect of, all or substantially all of the Holding LP's assets in a single transaction or series of transactions.

The Holding LP shall not dissolve if within 30 days of the date of dissolution (and provided that a notice of dissolution with respect to the Holding LP has not been filed with the Bermuda Monetary Authority), Brookfield executes a transfer deed pursuant to which the new general partner assumes the rights and undertakes the obligations of the original general partner, but only if the Holding LP receives an opinion of counsel that the admission of Brookfield as general partner will not result in the loss of limited liability of any limited partner of the Holding LP.

The Infrastructure GP LP may withdraw as general partner without first obtaining approval of unitholders by giving 90 days advance notice, and that withdrawal will not constitute a violation of the limited partnership agreement.

Upon the withdrawal of the Infrastructure GP LP, the holders of a majority of the voting power of outstanding units may select a successor to the Infrastructure GP LP. If a successor is not elected, or is elected but an opinion of counsel regarding limited liability, tax matters and the Investment Company Act (and similar legislation in other jurisdictions) cannot be obtained, the Holding LP will be dissolved, wound up and liquidated. See "—Dissolution" above.

The Infrastructure GP LP may not be removed unless that removal is approved by the vote of the holders of at least 66²/3% of the outstanding class of units that are not Redeemable Partnership Units and it receives an opinion of counsel regarding limited liability tax matters and the Investment

Company Act (and similar legislation in other jurisdictions). Any removal of the Infrastructure GP LP is also subject to the approval of a successor general partner by the vote of the holders of a majority of the voting power of its outstanding units.

In the event of removal of the Infrastructure GP LP under circumstances where cause exists or withdrawal of the Infrastructure GP LP where that withdrawal violates the Holding LP's limited partnership agreement, a successor general partner will have the option to purchase the general partnership interest of the Infrastructure GP LP for a cash payment equal to its fair market value. Under all other circumstances where the Infrastructure GP LP withdraws or is removed by the limited partners, the Infrastructure GP LP will have the option to require the successor general partner to purchase the general partnership interest of the Infrastructure GP LP for a cash payment equal to its fair market value. In each case, this fair market value will be determined by agreement between the Infrastructure GP LP and the successor general partner. If no agreement is reached within 30 days of the Infrastructure GP LP's departure, an independent investment banking firm or other independent expert selected by the Infrastructure GP LP and the successor general partner will determine the fair market value. If the Infrastructure GP LP and the successor general partner cannot agree upon an expert within 45 days of the Infrastructure GP LP's departure, then an expert chosen by agreement of the experts selected by each of them will determine the fair market value.

If the option described above is not exercised by either the departing general partner or the successor general partner, the departing general partner's general partnership interests will automatically convert into either class A units of the Holding LP or Redeemable Partnership Units pursuant to a valuation of those interests as determined by an investment banking firm or other independent expert selected in the manner described in the preceding paragraph.

The Infrastructure GP LP may transfer all or any part of its general partnership interests without first obtaining approval of any unitholder. As a condition of this transfer, the transferee must assume the rights and duties of the general partner to whose interest that transferee has succeeded, agree to be bound by the provisions of the Holding LP's limited partnership agreement and furnish an opinion of counsel regarding limited liability, tax matters and the Investment Company Act (and similar legislation in other jurisdictions). Any transfer of the general partnership interest is subject to prior notice to and approval of the relevant Bermuda regulatory authority. At any time, the members of the Infrastructure GP LP may sell or transfer all or part of their units in the Infrastructure GP LP without the approval of the unitholders.

The general partner of the Holding LP and their respective partners, members, shareholders, directors, officers, employees and shareholders, which we refer to as "interested parties", may become limited partners or beneficially interested in limited partners and may hold, dispose of or otherwise deal with units of the Holding LP with the same rights they would have if the general partner of the Holding LP were not a party to the limited partnership agreement of the Holding LP. An interested party will not be liable to account either to other interested parties or to the Holding LP, its partners or any other persons for any profits or benefits made or derived by or in connection with any such transaction.

The limited partnership agreement of the Holding LP permits an interested party to sell investments to, purchase assets from, vest assets in and enter into any contract, arrangement or transaction with the Holding LP, any of the Holding Entities, any operating entity or any other holding vehicle established by the Holding LP and may be interested in any such contract, transaction or arrangement and shall not be liable to account either to the Holding LP, any of the Holding Entities,

any operating entity or any other holding vehicle established by the Holding LP or any other person in respect of any such contract, transaction or arrangement, or any benefits or profits made or derived therefrom, by virtue only of the relationship between the parties concerned, subject to our conflicts policy.

Under the Holding LP's limited partnership agreement, the general partner will be required to maintain as its sole activity the role of the general partner of the Holding LP. The general partner will not be permitted to engage in any activity or incur any debts or liabilities except in connection with or incidental to its performance as general partner or acquiring, owning or disposing of debt or equity securities of a subsidiary of an Holding Entity or any other holding vehicle established by the Holding LP.

The Holding LP's limited partnership agreement provides that each person who is entitled to be indemnified by the partnership, as described below under "—Indemnification; Limitations on Liability" (other than the general partner) will have the right to engage in businesses of every type and description and other activities for profit, and to engage in and possess interests in business ventures of any and every type or description, irrespective of whether (i) such businesses and activities are similar to our activities, or (ii) such businesses and activities directly compete with, or disfavor or exclude, the Holding LP, its general partner, any Holding Entity, operating entity, or any other holding vehicle established by the Holding LP. Such business interests, activities and engagements will be deemed not to constitute a breach of the limited partnership agreement or any duties stated or implied by law or equity, including fiduciary duties, owed to any of the Holding LP, its general partner, any Holding Entity, operating entity, and any other holding vehicle established by the Holding LP (or any of their respective investors), and shall be deemed not to be a breach of its general partner's fiduciary duties or any other obligation of any type whatsoever of the general partner. None of the Holding LP, its general partner, any Holding Entity, operating entity, any other holding vehicle established by the Holding LP or any other person shall have any rights by virtue of the Holding LP's limited partnership agreement or the partnership relationship established thereby or otherwise in any business ventures of any person who is entitled to be indemnified by the Holding LP as described below under "—Indemnification; Limitations on Liability."

The Infrastructure GP LP and the other indemnified persons described in the preceding paragraph will not have any obligation under the Holding LP's 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 the Holding LP, any Holding Entity, operating entity, or any other holding vehicle established by the Holding LP. These provisions will not affect any obligation of such indemnified person to present business or investment opportunities to the Holding LP, any Holding Entity, operating entity or any other holding vehicle established by the Holding LP pursuant to a separate written agreement between such persons.

Pursuant to an amendment to the Holding LP's limited partnership agreement, the Infrastructure GP LP is required to prepare financial statements in accordance with IFRS. This amendment was made in conjunction with our partnership's amendment of its limited partnership agreement and subsequent adoption of IFRS as at and for the quarter ended March 31, 2010. See also the information contained in this annual report on Form 20-F under Item 10.B "Memorandum and Articles of Association—Description of Our Units and Our Limited Partnership Agreement—Accounts, Reports and Other Information". The Holding LP's financial statements must be made publicly available together with a statement of the accounting policies used in their preparation, such information as may be required by applicable laws and regulations and such information as the general

partner of the Holding LP deems appropriate. The Holding LP's annual financial statements must be audited by an independent accountant firm of international standing and made publicly available within such period of time as is required to comply with applicable laws and regulations, including any rules of any applicable securities exchange. The Holding LP's quarterly financial statements are unaudited and are made available publicly as and within the time period required by applicable laws and regulations.

The general partner of the Holding LP is also required to use commercially reasonable efforts to prepare and send to the Holding LP's limited partners on an annual basis, additional information regarding the Holding LP, including Schedule K-1 (or equivalent) and information related to the passive foreign investment company status of any non-U.S. corporation that we control and, where reasonably possible, any other non-U.S. corporation in which we hold an interest. The general partner of the Holding LP will also, where reasonably possible, prepare and send information required by the Holding LP's non-U.S. limited partners for U.S. federal income tax reporting purposes, including information related to investments in "U.S. real property interests," as that term is defined in Section 897 of the U.S. Internal Revenue Code. The general partner will also, where reasonably possible and applicable, prepare and send information required by the Holding LP's limited partners for Canadian federal income tax purposes.

The Infrastructure GP LP will deliver to our partnership (i) the financial statements of the Holding LP, and (ii) the accounts and financial statements of any Holding Entity or any other holding vehicle established by the Holding LP that is not consolidated with the Holding LP or any Holding Entity or holding vehicle whose accounts are subject to such approval.

Under the Holding LP's limited partnership agreement, it is required to indemnify to the fullest extent permitted by law its general partner, the Manager and any of their respective affiliates (and their respective officers, directors, agents, shareholders, partners, members and employees), any person who serves on a governing body of the Holding LP, a Holding Entity, operating entity or any other holding vehicle established by our partnership and any other person designated by its general partner as an indemnified person, in each case, against all losses, claims, damages, liabilities, costs or expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, incurred by an indemnified person in connection with its business, investments and activities or by reason of their holding such positions, except to the extent that the claims, liabilities, losses, damages, costs or expenses are determined to have resulted from the indemnified person's bad faith, fraud or willful misconduct, or in the case of a criminal matter, action that the indemnified person knew to have been unlawful. In addition, under the Holding LP's limited partnership agreement, (i) the liability of such persons has been limited to the fullest extent permitted by law, except to the extent that their conduct involves bad faith, fraud or willful misconduct, or in the case of a criminal matter, action that the indemnified person knew to have been unlawful and (ii) any matter that is approved by the independent directors will not constitute a breach of any duties stated or implied by law or equity, including fiduciary duties. The Holding LP's limited partnership agreement requires it to advance funds to pay the expenses of an indemnified person in connection with a matter in which indemnification may be sought until it is determined that the indemnified person is not entitled to indemnification.

The Holding LP's limited partnership agreement is governed by and will be construed in accordance with the laws of Bermuda.

The following are the only material contracts, other than contracts entered into in the ordinary course of business, to which we have been a party within the past two years:

Copies of the agreements noted above will be made available, free of charge, by our Managing General Partner and are available electronically on the website of SEC at www.sec.gov and on our SEDAR profile at www.sedar.com. Written requests for such documents should be directed to our Corporate Secretary at Canon's Court, 22 Victoria Street, Hamilton HM 12, Bermuda. Copies of the agreements noted above will also be available for inspection at the offices of the Manager at 181 Bay Street, Suite 300, Brookfield Place, Toronto, Ontario, M5J 2T3 during normal business hours.

There are currently no governmental laws, decrees, regulations or other legislation of Bermuda or the United States which restrict the import or export of capital or the remittance of dividends, interest or other payments to non-residents of Bermuda or the United States holding the Company's securities, except as otherwise described in this annual report on Form 20-F under Item 10.E "Taxation."

The following summary discusses certain material United States, Canadian and Bermudian tax considerations related to the holding and disposition of our units as of the date hereof. Holders of our units are advised to consult their own tax advisors concerning the consequences under the tax laws of the country of which they are resident or in which they are otherwise subject to tax of making an investment in our units.

This summary discusses certain United States federal income tax consequences related to the holding and disposition of units as of the date hereof. This summary is based on provisions of the U.S. Internal Revenue Code of 1986, as amended, or the U.S. Internal Revenue Code, on the regulations promulgated thereunder and on published administrative rulings, judicial decisions and other applicable authorities, all as in effect on the date hereof and all of which are subject to change at any time (possibly with retroactive effect). This summary is necessarily general and may not apply to all categories of investors, some of which may be subject to special rules (including, without limitation, investors that own more than 5% of our units, dealers in securities or currencies, financial institutions or financial services entities, life insurance companies, holders of our units held as part of a straddle, hedge, constructive sale or conversion transaction with other investments, U.S. Holders whose functional currency is not the U.S. dollar, persons who have elected mark-to-market accounting, persons who hold our units through a partnership or other entity which is a pass-through entity for U.S. federal income tax purposes, persons for whom our units are not a capital asset, or certain expatriates who meet the expatriation rules in Section 877 of the U.S. Internal Revenue Code or former long-term residents of the United States. Tax-exempt organizations are discussed separately below. The actual tax consequences of the ownership and disposition of our units will vary depending on your circumstances.

For purposes of this discussion, a "U.S. Holder" is a beneficial holder of one or more of our units that is for U.S. federal income tax purposes (1) an individual citizen or resident of the United States; (2) a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia; (3) an estate the income of which is subject to U.S. federal income taxation regardless of its source or (4) a trust which either (i) is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all substantial decisions of the trust or (ii) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person. A "non-U.S. Holder" is a holder that is not a U.S. Holder and who, in addition, is not (i) a partnership or other fiscally transparent entity, or (ii) an individual present in the United States for 183 days or more in a taxable year who meets certain other conditions under the substantial presence test under Section 7701(b)(3) of the U.S. Internal Revenue Code and U.S. Treasury Regulation Section 301.7701(b)-1(c).

If a partnership holds our units, the tax treatment of a partner of such partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding our units, you should consult your own tax advisors.

A non-U.S. Holder who holds more than 5% of our units may be subject to special rules under the Foreign Investment in Real Property Tax Act of 1980, or FIRPTA. For purposes of determining whether a non-U.S. Holder holds more than 5% of our units, special attribution rules apply. Where a non-U.S. person who holds (or is deemed to hold) more than 5% of our units disposes of units at a time when our partnership is a U.S. Real Property Holding Corporation, or USRPHC (which determination includes a five year look back period) any gain will be subject to U.S. taxation at 35%, and such non-U.S. person will have a U.S. tax return filing obligation. Our Managing General Partner does not believe that our partnership is currently, or has been, a USRPHC. Our partnership is not under any obligation to avoid becoming a USRPHC or to notify unitholders in the event that our Managing General Partner determines it becomes a USRPHC. If any unitholder is a non-U.S. person and owns or anticipates owning more than 5% of our units, such person should consult their tax advisors. The application of the FIRPTA rules to a non-U.S. Holder who holds (or is deemed to hold) more than 5% of our units would result in such non-U.S. Holder being liable for FIRPTA tax if such non-U.S. Holder disposes of our units at a time when we are a USRPHC or have at any time been a USRPHC within the shorter of such non-U.S. Holder's holding period or five years preceding the disposition.

This discussion does not constitute tax advice and is not intended to be a substitute for tax planning. You should consult your own tax advisors concerning the U.S. federal, state and local income tax consequences particular to your ownership and disposition of our units, as well as any consequences under the laws of any other taxing jurisdiction.

Each of our partnership and the Holding LP has made a protective election to be treated as a partnership for U.S. federal income tax purposes. An entity that is treated as a partnership for U.S. federal income tax purposes incurs no U.S. federal income tax liability. Instead, each partner is required to take into account its allocable share of items of income, gain, loss, and deduction of the partnership in computing its U.S. federal income tax liability, regardless of whether cash distributions are made. Distributions of cash by a partnership to a partner are generally not taxable unless the amount of cash distributed to a partner is in excess of the partner's adjusted basis in its partnership interest.

An entity that would otherwise be classified as a partnership for U.S. federal income tax purposes may nonetheless be taxable as a corporation if it is a "publicly traded partnership," unless an exception applies. Our partnership will be publicly traded; however, an exception, referred to as the "Qualifying Income Exception," exists with respect to a publicly traded partnership if at least 90% of such partnership's gross income for every taxable year consists of "qualifying income" and the partnership would not be required to register under the Investment Company Act if it were a U.S. corporation. Qualifying income includes certain interest income, dividends, real property rents, gains from the sale or other disposition of real property, and any gain from the sale or disposition of a capital asset or other property held for the production of income that otherwise constitutes qualifying income. Our Managing General Partner, and the Infrastructure General Partner, intend to manage our affairs so that our partnership will meet the Qualifying Income Exception in each taxable year.

In 2010, Legislation was introduced into the U.S. Congress and passed by the U.S. House of Representatives (H.R. 4213, the American Jobs and Closing Tax Loopholes Act of 2010, or the Act), which, if it had been finally enacted into law and applicable to our partnership, could have had adverse consequences, including (a) the re-characterization of capital gain income as "ordinary income", (b) potential reclassification of qualified dividend income as "ordinary income" subject to a higher rate of U.S. income tax, (c) uncertain treatment for non-U.S. partners on certain types of U.S. source income, and (d) significant limitations on the ability of our partnership to meet the "qualifying income" exception for taxation as a partnership for U.S. federal income tax purposes. However, such legislation

was never passed by the U.S. Senate and was not enacted into law. Recently, President Obama has reintroduced as part of his fiscal year 2012 budget proposal a similar concept of re-characterizing certain items of capital gain income as "ordinary income", but such proposal lacks sufficient details to determine its full scope and any potential application to our partnership. At this time it remains unclear whether any legislation related to such budget proposal, or legislation similar to H.R. 4213, will be proposed or enacted by the U.S. Congress, and if enacted, whether and how any such legislation would apply to our partnership. In view of the potential significance of any such U.S. federal income tax law changes and the fact that there are likely to be ongoing developments in this area, you should consult your own tax advisor as to the potential effects the proposed legislation might have on an investment in our partnership. Subject to the foregoing, our Managing General Partner believes our partnership will be treated as a partnership and not as a corporation for U.S. federal income tax purposes. The remainder of this section assumes that the proposed tax legislation, even if enacted, would not be applicable to our partnership or to Brookfield Infrastructure.

If our partnership fails to meet the Qualifying Income Exception, other than a failure which is determined by the U.S. Internal Revenue Service, or the IRS, to be inadvertent and which is cured within a reasonable time after discovery, or if our partnership is required to register under the Investment Company Act, our partnership will be treated as if it had transferred all of its assets, subject to liabilities, to a newly formed corporation, on the first day of the year in which our partnership fails to meet the Qualifying Income Exception, in return for stock in that corporation, and then distributed the stock to the holders of our units in liquidation thereof. This deemed contribution would likely result in recognition of gain (but not loss) to U.S. Holders. However, U.S. Holders actually or constructively owning less than 5% of our units generally would not recognize the portion of such gain attributable to stock or securities of non-U.S. corporations which we may hold. If, at the time of the contribution, our partnership has liabilities in excess of the tax basis of its assets, all U.S. Holders would generally recognize gain in respect of such excess liabilities upon the deemed transfer. Afterwards, our partnership would be treated as a corporation for U.S. federal income tax purposes.

If our partnership were treated as a corporation in any taxable year, either as a result of a failure to meet the Qualifying Income Exception or otherwise, our partnership's items of income, gain, loss and deduction would be reflected only on our partnership's tax return rather than being passed through to holders of our units, and our partnership would be subject to U.S. corporate income tax and branch profits tax with respect to its income, if any, that is effectively connected with a U.S. trade or business. Moreover, under certain circumstances, our partnership may be classified as a PFIC, for U.S. federal income tax purposes, and you would be subject to the rules applicable to PFICs discussed below. See "—Consequences to U.S. Holders—Passive Foreign Investment Companies". Subject to the PFIC rules discussed below, distributions made to U.S. Holders would be treated as either taxable dividend income, which may be eligible for reduced rates of taxation (if such distributions are made prior to January 1, 2011, and are made in respect of our units traded on the NYSE or certain other requirements are satisfied), to the extent of our partnership's current or accumulated earnings and profits, or in the absence of earnings and profits, as a nontaxable return of capital, to the extent of the holder's tax basis in our units, or as taxable capital gain, after the holder's basis is reduced to zero. In addition, dividends, interest and certain other passive income that our partnership receives with respect to U.S. investments generally would be subject to U.S. withholding tax at a rate of 30% (although certain non-U.S. Holders nevertheless may be entitled to certain treaty benefits in respect of their allocable share of such income) and U.S. Holders would not be allowed a tax credit with respect to any such tax withheld. In addition, the "portfolio interest" exemption would not apply to certain interest income of our partnership (although certain non-U.S. Holders nevertheless may be entitled to certain treaty benefits in respect of their allocable share of such income). Accordingly, treatment of our partnership as a corporation could materially reduce a holder's after-tax return and, thus, could result in a substantial reduction of the value of our units. If Brookfield Infrastructure were to be treated as a

corporation for U.S. federal income tax purposes, consequences similar to those described above would apply.

The remainder of this section assumes that our partnership and the Holding LP will be treated as partnerships for U.S. federal income tax purposes. We expect that a substantial portion of the items of income, gain, deduction, loss and credit realized by our partnership will be realized in the first instance by Brookfield Infrastructure and allocated to our partnership for reallocation to our unitholders. Unless otherwise specified, references in this section to realization of our partnership's items of income, gain, loss, deduction or credit include a realization of such items by Brookfield Infrastructure and the allocation of such items to our partnership.

Income and Loss. If you are a U.S. Holder, you will be required to take into account, as described below, your distributive share of our partnership's items of income, gain, loss, deduction and credit for each of our partnership's taxable years ending with or within your taxable year. Each item generally will have the same character and source (either U.S. or foreign) as though you had realized the item directly. You will report those items without regard to whether any distribution has been or will be received from our partnership. Although we intend to make cash distributions (which we intend to pay to all of our unitholders on a quarterly basis) in an amount that is generally expected to be sufficient to permit our U.S. Holders to fund their estimated U.S. tax obligations (including any U.S. federal, state and local income taxes) with respect to their distributive shares of our partnership's net income or gain, based upon your particular tax situation and simplifying assumptions that we will make in determining the amount of such distributions, and whether or not you elect to reinvest such distributions pursuant to the distribution reinvestment plan, your tax liability may exceed cash distributions made to you, in which case you would have to satisfy tax liabilities arising from your units in our partnership from your own funds.

With respect to U.S. Holders who are individuals, certain dividends paid by a corporation, including certain qualified foreign corporations, to us and that are allocable to such U.S. Holders prior to January 1, 2013 may qualify for reduced rates of taxation. A qualified foreign corporation includes a foreign corporation that is eligible for the benefits of specified income tax treaties with the United States. In addition, a foreign corporation is treated as a qualified corporation with respect to its shares that are readily tradable on an established securities market in the United States. Among other exceptions, U.S. Holders who are individuals will not be eligible for reduced rates of taxation on any dividends if the payer is a PFIC in the taxable year in which such dividends are paid or in the preceding taxable year. U.S. Holders that are corporations may be entitled to a "dividends received deduction" in respect of dividends paid by U.S. corporations in which we own stock. You should consult your own tax advisors regarding the application of the foregoing rules to your particular circumstances.

For U.S. federal income tax purposes, your allocable share of our partnership's items of income, gain, loss, deduction or credit will be governed by our limited partnership agreement if such allocations have a "substantial economic effect" or are determined to be in accordance with your interest in our partnership. Similarly, our partnership's allocable share of items of income, gain, loss, deduction or credit of Brookfield Infrastructure will be governed by the limited partnership agreement of Brookfield Infrastructure if such allocations have "substantial economic effect" or are determined to be in accordance with our partnership's interest in Brookfield Infrastructure. Our Managing General Partner and the Infrastructure Partner believe that, for U.S. federal income tax purposes, such allocations should be given effect, and our Managing General Partner and the Infrastructure General Partner intend to prepare tax returns based on such allocations. If the IRS successfully challenged the allocations made pursuant to either our limited partnership agreement or the limited partnership

agreement of Brookfield Infrastructure, the resulting allocations for U.S. federal income tax purposes may be less favorable than the allocations set forth in such agreements.

Basis. You will have an initial tax basis for your units equal to the sum of (i) the amount of cash paid for our units (or, if you received your units pursuant to the spin-off, the amount of dividend income you recognized pursuant to the spin-off) and (ii) your share of our partnership's liabilities, if any. That basis will be increased by your share of our partnership's income and by increases in your share of our partnership's liabilities, if any. That basis will be decreased, but not below zero, by distributions you receive from our partnership, by your share of our partnership's losses and by any decrease in your share of our partnership's liabilities. Under applicable U.S. federal income tax rules, a partner in a partnership has a single, or "unitary," tax basis in his or her partnership interest. As a result, any amount you pay to acquire additional units in our partnership (including through the distribution reinvestment plan) will be averaged with the adjusted tax basis of our units you owned prior to the acquisition of such additional units. The amount you pay to acquire additional units cannot be "traced" to the additional units so acquired. Certain consequences of your "unitary" tax basis are discussed in greater detail below in "Special Considerations for Purchasers of Additional units."

For purposes of the foregoing rules, the rules discussed immediately below, and the rules applicable to a sale or your units, our partnership's liabilities will generally include our partnership's share of any liabilities of Brookfield Infrastructure.

Limits on Deductions for Losses and Expenses. Your deduction of your share of our partnership's losses will be limited to your tax basis in your units and, if you are an individual or a corporate holder that is subject to the "at risk" rules, to the amount for which you are considered to be "at risk" with respect to our partnership's activities, if that is less than your tax basis. In general, you will be at risk to the extent of your tax basis in your units, reduced by (i) the portion of that basis attributable to your share of our partnership's liabilities for which you will not be personally liable (excluding certain qualified non-recourse financing) and (ii) any amount of money you borrow to acquire or hold your units, if the lender of those borrowed funds owns an interest in us, is related to you, or can look only to your units for repayment. Your at risk amount will generally increase by your allocable share of our partnership's income and gain and decrease by cash distributions you receive from our partnership and your allocable share of losses and deductions. You must recapture losses deducted in previous years to the extent that distributions cause your at risk amount to be less than zero at the end of any taxable year. Losses disallowed or recaptured as a result of these limitations will carry forward and will be allowable to the extent that your tax basis or at risk amount, whichever is the limiting factor, subsequently increases. Upon the taxable disposition of your units, any gain recognized by you can be offset by losses that were previously suspended by the at risk limitation but may not be offset by losses suspended by the basis limitation. Any excess loss above that gain previously suspended by the at risk or basis limitations may no longer be used. You should consult your own tax advisors as to the effects of the at risk rules.

Limitations on Deductibility of Organizational Expenses and Syndication Fees. In general, neither our partnership nor any U.S. Holder may deduct organizational or syndication expenses. Similar rules apply to organizational or syndication expenses incurred by Brookfield Infrastructure. While an election may be made by a partnership to amortize organizational expenses over a 15-year period, we do not intend to make such election for either our partnership or Brookfield Infrastructure. Syndication fees (which would include any sales or placement fees or commissions) must be capitalized and cannot be amortized or otherwise deducted.

Limitations on Interest Deductions. Your share of our partnership's interest expense is likely to be treated as "investment interest" expense. If you are a non-corporate taxpayer, the deductibility of "investment interest" expense is generally limited to the amount of your "net investment income." Your share of our partnership's dividend and interest income will be treated as investment income, although

"qualified dividend income" subject to reduced rates of tax in the hands of an individual will only be treated as investment income if you elect to treat such dividend as ordinary income not subject to reduced rates of tax. In addition, state and local tax laws may disallow deductions for your share of our partnership's interest expense.

Net investment income includes gross income from property held for investment and amounts treated as portfolio income under the passive loss rules less deductible expenses, other than interest, directly connected with the production of investment income, but generally does not include gains attributable to the disposition of property held for investment.

Deductibility of Partnership Investment Expenditures by Individual Partners and by Trusts and Estates. Subject to certain exceptions, all miscellaneous itemized deductions of an individual taxpayer, and certain of such deductions of an estate or trust, are deductible only to the extent that such deductions exceed 2% of the taxpayer's adjusted gross income. Moreover, absent U.S. Congressional action, after December 31, 2012, the otherwise allowable itemized deductions of individuals whose gross income exceeds an applicable threshold amount are subject to reduction by an amount equal to the lesser of (i) 3% of the excess of the individual's adjusted gross income over the threshold amount, or (ii) 80% of the amount of the itemized deductions. The operating expenses of our partnership, including our partnership's allocable share of the base management fee or any other management fees (if any), will likely be treated as miscellaneous itemized deductions subject to the foregoing rule. Alternatively, it is possible that our partnership and the Holding LP will be required to capitalize amounts paid in respect of the base management fee (as well as amounts paid in respect of any other management fees (if any)). Accordingly, if you are a non-corporate U.S. Holder, you should consult your own tax advisors with respect to the application of these limitations.

You will recognize gain or loss on a sale by you of our units equal to the difference, if any, between the amount realized and your tax basis in our units sold. Your amount realized will be measured by the sum of the cash or the fair market value of other property received plus your share of our partnership's liabilities, if any.

Gain or loss recognized by you on the sale or exchange by you of our units will generally be taxable as capital gain or loss and will be long-term capital gain or loss if our units were held for more than one year on the date of such sale or exchange. Under certain circumstances, your gain or loss may be long-term capital gain or loss, in part, and short-term capital gain or loss, in part, under the "split" holding period rules discussed below in "Special Considerations for Purchasers of Additional Units." Assuming you have not elected to treat your share of our interest in any PFICs in which we may invest as a "qualified electing fund", gain attributable to such investment in a PFIC would be taxable in the manner described below in "—Passive Foreign Investment Companies". In addition, certain gain attributable to "unrealized receivables" or "inventory items" could be characterized as ordinary income rather than capital gain. For example, if our partnership holds debt acquired at a market discount, accrued market discount on such debt would be treated as "unrealized receivables." The deductibility of capital losses is subject to limitations.

Where a partner in a partnership acquires portions of his or her interest at different times, applicable U.S. federal income tax rules provide that the partner has a divided, or "split" holding period in his or her interest. Thus, if you acquire additional units at different times (including acquisitions made through the distribution reinvestment plan) each unit you own (including the additional units you acquire) will have a "split" holding period: a fraction of each unit will have a holding period commencing on the date after the acquisition of the additional units under the plan, and a fraction of each unit will have a holding period attributable to your previously-owned, or historic,

units, based on the relative fair market values of the additional units and the historic units (as of the date of the acquisition of the additional units). The foregoing rules apply each time you acquire additional units (including under the distribution reinvestment plan). Nonetheless, each unit will retain an "averaged" adjusted tax basis as described above in "Basis.".

Subject to the special tracing approach described below, if you dispose of any units (whether historic or additional units) within one year of acquiring additional units, the disposition may give rise to both short- term capital gain (or loss), in part, and long-term capital gain (or loss), in part, as a result of each unit's "split" holding period. Likewise, a cash distribution to you within a year of the acquisition of additional units in excess of your "unitary" adjusted tax basis in all of your units could give rise to both short-term and long-term capital gain.

You may under certain circumstances use a "tracing" approach in lieu of having a "split" holding period in your units. The U.S. Treasury Regulations provide that a selling partner in a "publicly traded partnership" may use the actual holding period of the portion of his or her partnership interest if (1) the interest is divided into identifiable units with ascertainable holding periods, (2) the partner can identify the portion of the partnership interest transferred, and (3) the partner elects to use the identification method for all sales or exchanges of his or her interests in the partnership. As described above, our partnership will be a "publicly traded partnership." If you intend to rely on this alternative tracing approach, you must make an election to do so with your first disposition of units. This election applies only to your holding period in your units, not to your basis, which you may not "trace" under the "unitary" tax basis rules described above.

You should consult your own tax advisors regarding the consequences of a "split" holding period in your units, as well the availability and advisability of making the alternative tracing election.

You will generally be entitled to a foreign tax credit with respect to your allocable share of creditable foreign taxes paid on our partnership's income and gains. Complex rules may, depending on your particular circumstances, limit the availability or use of foreign tax credits. Gains from the sale of our partnership's investments may be treated as U.S. source gains. Consequently, you may not be able to use the foreign tax credit arising from any foreign taxes imposed on such gains unless such credit can be applied (subject to applicable limitations) against U.S. tax due on other income treated as derived from foreign sources. Certain losses that our partnership incurs may be treated as foreign source losses, which could reduce the amount of foreign tax credits otherwise available.

Our partnership and the Holding LP have each made the election permitted by Section 754 of the U.S. Internal Revenue Code (the "the Section 754 Election"). The Section 754 Election is irrevocable without the consent of the IRS. The Section 754 Election generally requires our partnership to adjust the tax basis in its assets, or inside basis, attributable to a transferee of our units under Section 743(b) of the U.S. Internal Revenue Code to reflect the purchase price paid by the transferee for our units. This election does not apply to a person who purchases our units directly from us. For purposes of this discussion, a transferee's inside basis in our partnership's assets will be considered to have two components: (i) the transferee's share of our partnership's tax basis in our partnership's assets, or common basis, and (ii) the adjustment under Section 743(b) of the U.S. Internal Revenue Code to that basis. The foregoing rules would also apply to Brookfield Infrastructure.

Generally, a Section 754 Election would be advantageous to a transferee U.S. Holder if such U.S. Holder's tax basis in its units is higher than our units' share of the aggregate tax basis of our partnership's assets immediately prior to the transfer. In that case, as a result of the Section 754 Election, the transferee U.S. Holder would have a higher tax basis in such U.S. Holder's share of our

partnership's assets for purposes of calculating, among other items, such U.S. Holder's share of any gain or loss on a sale of our partnership's assets. Conversely, a Section 754 Election would be disadvantageous to a transferee U.S. Holder if such U.S. Holder's tax basis in its units is lower than those units' share of the aggregate tax basis of our partnership's assets immediately prior to the transfer. Thus, the fair market value of our units may be affected either favorably or adversely by the election.

The calculations involved in the Section 754 Election are complex, and our Managing General Partner and the Infrastructure General Partner advise that they will make them on the basis of assumptions as to the value of our assets and other matters. You should consult your own tax advisors as to the effects of the Section 754 Election.

Because we cannot match transferors and transferees of our units, we must maintain uniformity of the economic and tax characteristics of our units to a purchaser of our units. In the absence of uniformity, we may be unable to comply fully with a number of U.S. federal income tax requirements. A lack of uniformity can result from a literal application of Treasury Regulations under Section 743 of the U.S. Internal Revenue Code to our partnership's Section 743(b) adjustments, the determination that our partnership's Section 704(c) allocations are unreasonable, or other reasons. Section 704(c) allocations would be intended to reduce or eliminate the disparity between tax basis and the value of our partnership's assets in certain circumstances, including on the issuance of additional units. In order to maintain the fungibility of all of our units at all times, we seek to achieve the uniformity of U.S. tax treatment for all purchasers of our units which are acquired at the same time and price (irrespective of the identity of the particular seller of our units or the time when our units are issued by our partnership) through the application of certain tax accounting principles that our Managing General Partner believes are reasonable for our partnership. However, the IRS may disagree with us and may successfully challenge our application of such tax accounting principles. Any non-uniformity could have a negative impact on the value of our units.

Our partnership's functional currency will be the U.S. dollar, and our partnership's income or loss will be calculated in U.S. dollars. It is likely that our partnership will recognize "foreign currency" gain or loss with respect to transactions involving non-U.S. dollar currencies. In general, foreign currency gain or loss is treated as ordinary income or loss. You should consult your own tax advisors regarding the tax treatment of foreign currency gain or loss.

A U.S. Holder will be subject to special rules applicable to indirect investments in foreign corporations, including an investment in a PFIC.

A PFIC is defined as any foreign corporation with respect to which (after applying the applicable look-through rules under Section 1297(c) of the U.S. Internal Revenue Code) either (i) 75% or more of its gross income for a taxable year is "passive income" or (ii) 50% or more of its assets in any taxable year (generally based on the quarterly average of the value of its assets) produce "passive income." There are no minimum stock ownership requirements for PFICs. Once a corporation qualifies as a PFIC it is as to any person with an interest in such corporation at any time at which it was a PFIC, subject to certain exceptions, always treated as a PFIC, regardless of whether it satisfies either of the qualification tests in subsequent years. Any gain on disposition of stock of a PFIC, as well as income realized on certain "excess distributions" by the PFIC, is treated as though realized ratably over the shorter of your holding period of our units or our holding period for the PFIC. Such gain or income is taxable as ordinary income and dividends paid by a PFIC are not eligible for the preferential

tax rate in the hands of individuals who would otherwise be eligible for the preferential tax rate for dividends. In addition, an interest charge would be imposed on you based on the tax deferred from prior years.

If you made an election to treat your share of our interest in a PFIC as a "qualified electing fund", such election a "QEF election", for the first year you are treated as holding such interest, in lieu of the foregoing treatment, you would be required to include in income each year a portion of the ordinary earnings and net capital gains of the PFIC, even if not distributed to our partnership or to you. A QEF election must be made by you on an entity-by-entity basis. To make a QEF election, you would, among other things, be required to (a) obtain an information statement (through an intermediary statement supplied by our partnership) with respect to the PFIC and (b) prepare and submit IRS Form 8621 with your annual income tax return. Once you make a QEF election for an entity, such election applies to any additional shares of interest in such entity acquired directly or indirectly, including through additional units acquired after the QEF election is made (such as units acquired under the distribution reinvestment plan). If you make a QEF election after the first year that you are treated as holding in interest in a PFIC, the adverse tax consequences relating to PFIC stock will continue to apply with respect to the pre-QEF election period, unless you make a "purging election". The purging election would create a deemed sale of your previously held share of our interests in a PFIC. The gain recognized by the purging election would be subject to the special tax and interest charge rules, which treat the gain as an excess distribution, as described above. As a result of the purging election, you would have a new basis and holding period in your share of our interests in the PFIC. U.S. Holders should consult their own tax advisors as to the manner in which such direct inclusions affect their allocable share of our income and their tax basis in their units and the advisability of making a QEF election or a purging election.

Alternatively, in the case of a PFIC that is a publicly traded foreign company, an election may be made to "mark-to-market" the stock of such foreign portfolio company on an annual basis. Once you make a "mark-to-market" election, such election applies to any additional shares of interest in such entity acquired directly or indirectly, including through additional units acquired after the "mark-to-market" election is made (such as units acquired under the distribution reinvestment plan). Pursuant to such an election, you would include in each year as ordinary income the excess, if any, of the fair market value of such stock over its adjusted basis at the end of the taxable year. You may treat as ordinary loss any excess of the adjusted basis of the stock over its fair market value at the end of the year, but only to the extent of the net amount previously included in income as a result of the election. Although we may in the future acquire PFICs which are publicly traded foreign companies, it is not expected that interests in any of our current operations will be publicly traded. Thus, a U.S. Holder would not be eligible to make a mark-to-market election in respect of its indirect ownership interest in any of our operating entities.

Based on our analysis of our operating entities and Holding Entities, our Managing General Partner and the Infrastructure General Partner believe that some of the operating entities may be PFICs. Our partnership and the Holding LP intend to dispose of some existing PFICs by December 31, 2011. However, there can be no assurance that a current or future investment will not qualify as a PFIC or that an investment in PFIC stock will be eligible for the "mark-to-market" election. In addition, we may be required to hold an existing or future operating entity through a Holding Entity that would be a PFIC in order to ensure that our partnership satisfies the Qualifying Income Exception. See "—Investment Structure", below. To the extent reasonably practicable, we intend to timely provide you with information related to the PFIC status of each entity we are able to identify as a PFIC, including information necessary to make a QEF election with respect to each such entity. To the extent reasonably practicable, we intend to make distributions of the earnings of each entity we are able to identify as a PFIC not less frequently than annually so as to minimize the likelihood that you will have excess distributions with respect to any such entity. However, because we cannot assure that will be the case, and because any gains on a sale of any such entity would remain subject to the PFIC

tax regime discussed above (see also "Sale or Exchange of Our Units," above), we urge you to consider timely filing a QEF election with respect to each entity we are able to identify as a PFIC and for which we are able to provide the necessary information for the first year we hold an interest in such entity (or for the first year you held units, if later).

An investment in a PFIC may create a reporting obligation under the "Foreign Bank and Financial Account Reporting" rules as discussed below. Recently enacted U.S. legislation requires each U.S. person who directly or indirectly owns an interest in a PFIC to file an annual report with the IRS and failure to file such report could result in the imposition of penalties on such U.S. person. You should consult your own tax advisors regarding the PFIC rules, including the potential effects this legislation might have on your filing requirements and the advisability of making a QEF election or, if applicable, a mark-to-market election, with respect to each PFIC.

To manage our affairs so as to ensure that our partnership meets the Qualifying Income Exception for the publicly traded partnership rules (discussed above) and comply with certain requirements in our limited partnership agreement, we may need to structure certain investments through an entity classified as a corporation for U.S. federal income tax purposes. Such investment structures will be entered into as determined in the sole discretion of our Managing General Partner and the Infrastructure General Partner in order to create a tax structure that generally is efficient for our unitholders. However, because our unitholders will be located in numerous taxing jurisdictions, no assurances can be given that any such investment structure will be beneficial to all our unitholders to the same extent, and may even impose additional tax burdens on some of our unitholders. As discussed above, if any such entity were a non-U.S. corporation it may be considered a PFIC. If any such entity were a U.S. corporation, it would be subject to U.S. federal income tax on its operating income, including any gain recognized on its disposal of its investments. In addition, if the investment involves U.S. real property, gain recognized on disposition of the investment by a corporation would generally be subject to corporate-level tax, whether the corporation is a U.S. or a non-U.S. corporation.

In addition to U.S. federal income tax consequences, because of an investment in our partnership, you may be subject to potential U.S. state and local taxes in the U.S. state or locality in which you are a resident for tax purposes. You may also be subject to tax return filing obligations and income, franchise or other taxes, including withholding taxes, in non-U.S. jurisdictions in which we invest. We will attempt, to the extent reasonably practicable, to structure our operations and investments so as to avoid income tax filing obligations by our investors in non-U.S. jurisdictions, but, there may be circumstances in which we are unable to do so. Income or gains from investments held by us may be subject to withholding or other taxes in jurisdictions outside the United States, subject to the possibility of reduction under applicable income tax treaties. If you wish to claim the benefit of an applicable income tax treaty, you may be required to submit information to tax authorities in such jurisdictions. You should consult your own tax advisors regarding the U.S. state, local and non-U.S. tax consequences of an investment in our partnership.

Although each U.S. Holder is required to provide us with a Form W-9, we nevertheless may be unable to accurately or timely determine the tax status of our investors for purposes of determining whether U.S. withholding applies to payments made by our partnership to some or all of our unitholders. In such a case, payments made by our partnership to U.S. Holders may be subject to U.S. "backup" withholding at the applicable rate (currently 28%) or other U.S. withholding taxes (potentially as high as 30%). You would be able to treat as a credit your allocable share of any

U.S. withholding taxes paid in the taxable year in which such withholding taxes were paid and, as a result, you may be entitled to a refund of such taxes from the IRS. In the event you transfer or otherwise dispose of some or all of your units, special rules may apply for purposes of determining whether you or the transferee of such units is subject to U.S. withholding taxes in respect of income allocable to, or distributions made on account of, such units and/or entitled to refunds of any such taxes withheld. See below "Administrative Matters—Certain Effects of a Transfer of Units". You should consult your own tax advisors regarding the treatment of U.S. withholding taxes.

Our partnership may allocate items of income, gain, loss, deduction and credit using a monthly or other convention, whereby any such items recognized in a given month by our partnership are allocated to the holders of our units as of a specified date of such month. As a result, if you transfer your units, you may be allocated income, gain, loss and deduction realized by our partnership after the date of transfer. Similarly, if you acquire additional units, you may be allocated income, gain, loss, and deduction realized by our partnership prior to your ownership of such units.

Although Section 706 of the U.S. Internal Revenue Code generally provides guidelines for allocations of items of partnership income and deductions between transferors and transferees of partnership interests, it is not clear that our partnership's allocation method complies with its requirements. If our partnership's convention were not permitted, the IRS might contend that our partnership's taxable income or losses must be reallocated among our unitholders. If such a contention were sustained, your respective tax liabilities would be adjusted to your possible detriment. Our Managing General Partner is authorized to revise our partnership's method of allocation between transferors and transferees (as well as among investors whose interests otherwise vary during a taxable period).

If our units are included in the gross estate of a U.S. citizen or resident for U.S. federal estate tax purposes, then a U.S. federal estate tax might be payable in connection with the death of such person. Individual U.S. Holders should consult their own tax advisors concerning the potential U.S. federal estate tax consequences with respect to our units.

Income recognized by a U.S. tax-exempt organization is exempt from U.S. federal income tax except to the extent of the organization's "unrelated business taxable income", or "UBTI". UBTI is defined generally as any gross income derived by a tax-exempt organization from an unrelated trade or business that it regularly carries on, less the deductions directly connected with that trade or business. In addition, income arising from a "flow through" entity for U.S. federal income tax purposes that holds operating assets or is otherwise engaged in a trade or business will generally constitute UBTI. Notwithstanding the foregoing, UBTI generally does not include any dividend income, interest income (or certain other categories of passive income) or capital gains recognized by a tax-exempt organization so long as such income is not debt financed, as discussed below. Our Managing General Partner believes that our partnership will not be engaged in a trade or business, and anticipates that any operating assets held by us will be held through entities that are treated as corporations for U.S. federal income tax purposes.

The exclusion from UBTI for dividends, interest (or other passive income) and capital gains does not apply to income from "debt-financed property", which is treated as UBTI to the extent of the percentage of such income that the average acquisition indebtedness with respect to the property bears to the average tax basis of the property for the taxable year. A portion of any gain and other income attributable to the sale of previously "debt-financed property" can remain being treated as UBTI for up

to 12 months after such acquisition indebtedness is satisfied. If an entity treated as a partnership for U.S. federal income tax purposes incurs acquisition indebtedness, a tax-exempt partner in such partnership would be deemed to have acquisition indebtedness equal to its allocable portion of such acquisition indebtedness. Our partnership and the Holding LP are not prohibited from incurring indebtedness, and at times either or both may do so. If any such indebtedness were used to acquire property by our partnership or by Brookfield Infrastructure, such property generally would constitute "debt-financed property" and any income or gain realized on such debt-financed property (including a portion of any income or gain realized that is subject to the 12 month rule) and allocated to a tax-exempt entity generally would constitute "unrelated business taxable income" to such tax-exempt entity. In addition, even if such indebtedness were not used either by our partnership or by Brookfield Infrastructure to acquire property but were instead used to fund distributions to our unitholders, if a tax-exempt entity subject to taxation in the United States used such proceeds to make an investment outside our partnership, the IRS could assert that such investment constitutes "debt-financed property" to such unitholder with the consequences noted above. Our partnership and the Holding LP intend not to have directly had, after December 31, 2009, any outstanding indebtedness that was used to acquire property, and thus the Managing General Partner and the Infrastructure General Partner do not believe that our partnership or Brookfield Infrastructure will generate UBTI due to "debt-financed property" in the future. (Holding Entities, which are not partnerships, which are directly or indirectly owned by our partnership and the Holding LP have incurred acquisition indebtedness and may continue to incur acquisition indebtedness in the future).

A tax-exempt organization is subject to U.S. federal income tax at the regular graduated rates on the net amount of its UBTI, and a tax-exempt organization deriving gross income characterized as UBTI that exceeds $1,000 in any taxable year is obligated to file a U.S. federal income tax return, even if it has no liability for that year as a result of deductions against such gross income, including an annual $1,000 statutory deduction. Tax-exempt U.S. Holders should consult their own tax advisors regarding all aspects of UBTI.

U.S. mutual funds that are treated as regulated investment companies, or RICs, for U.S. federal income tax purposes are required, among other things, to meet an annual 90% gross income and a quarterly 50% asset value test under Section 851(b) of the U.S. Internal Revenue Code to maintain their favorable U.S. federal income tax status. The treatment of an investment by a RIC in our units for purposes of these tests will depend on whether our partnership will be treated as a "qualified publicly traded partnership". If our partnership is so treated, then our units themselves are the relevant assets for purposes of the 50% asset value test and the net income from our units is the relevant gross income for purposes of the 90% gross income test. If, however, our partnership is not so treated, then the relevant assets are the RIC's allocable share of the underlying assets held by our partnership and the relevant gross income is the RIC's allocable share of the underlying gross income earned by our partnership. Whether our partnership will qualify as a "qualified publicly traded partnership" depends on the exact nature of its future investments, but our Managing General Partner believes it is likely that our partnership will not be treated as a "qualified publicly traded partnership." RICs should consult their own tax advisors about the U.S. tax consequences of an investment in our units.

Our Managing General Partner and the Infrastructure General Partner intend to use commercially reasonable efforts to structure the activities of our partnership and of Brookfield Infrastructure 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. Specifically, our partnership will not make an investment directly, or through an entity which would be treated as a pass-through entity for U.S. federal income tax purposes,

if our Managing General Partner believes at the time of such investment that such investment would generate income treated as effectively connected with a U.S. trade or business. If, as anticipated, our partnership is not treated as engaged in a U.S. trade or business or as deriving income which is treated as effectively connected with a U.S. trade or business, and provided that you are not yourself engaged in a U.S. trade or business, you will not be subject to U.S. tax return filing requirements and generally will not be subject to U.S. federal income tax on interest and dividends from non-U.S. sources and gains from the sale or other disposition of securities or of real property located outside of the United States derived by us.

However, there can be no assurance that the law will not change or that the IRS will not challenge our Managing General Partner's position that our partnership is not engaged in a U.S. trade or business. If, contrary to our Managing General Partner's expectations, our partnership is considered to be engaged in a U.S. trade or business, you would be required to file a U.S. federal income tax return even if no effectively connected income is allocable to you. Additionally if our partnership has income that is treated as effectively connected with a U.S. trade or business, you would be required to report that income and would be subject to U.S. federal income tax at the regular graduated rates. In addition, we may be required to withhold U.S. federal income tax on your share of such income. If you are a non-U.S. corporation, you also may be subject to branch profits tax at a rate of 30%, or at a lower treaty rate, if applicable.

In general, even if our partnership is not engaged in a U.S. trade or business, and assuming you are not otherwise engaged in a U.S. trade or business, you will nonetheless be subject to a withholding tax of 30% on the gross amount on certain U.S.-source income which is not effectively connected with a U.S. trade or business. Income subjected to such a flat tax rate is income of a fixed or determinable annual or periodic nature, including dividends and certain interest income. Such withholding tax may be reduced or eliminated with respect to certain types of income under an applicable income tax treaty between the United States and your country of residence or under the "portfolio interest" rules of the U.S. Internal Revenue Code, provided that you provide proper certification as to your eligibility for such treatment. Notwithstanding the foregoing, and although each non-U.S. Holder is required to provide us with a Form W-8, we nevertheless may be unable to accurately or timely determine the tax status of our investors for purposes of establishing whether reduced rates of withholding apply to some or all of our investors. In such a case, your allocable share of distributions of U.S.-source dividend and interest income will be subject to U.S. withholding tax at a rate of 30%. As such, if you would not be subject to U.S. tax based on your tax status or are eligible for a reduced rate of U.S. withholding, you may need to take additional steps to receive a credit or refund of any excess withholding tax paid on your account, which may include the filing of a non-resident U.S. income tax return with the IRS. Among other limitations applicable to claiming treaty benefits, if you reside in a treaty jurisdiction which does not treat our partnership as a pass-through entity, you may not be eligible to receive a refund or credit of excess U.S. withholding taxes paid on your account. In the event you transfer or otherwise dispose of some or all of your units, special rules may apply for purposes of determining whether you or the transferee of such units are subject to U.S. withholding taxes in respect of income allocable to, or distributions made on account of, such units and/or entitled to refunds of any such taxes withheld. See "—Administrative Matters—Certain Effects of a Transfer of units". Additionally, under recently enacted U.S. legislation, certain payments of U.S. source income made after December 31, 2012, (including payments attributable to dispositions of property which produced (or could produce) certain U.S. source income) made to us or by us to or through non-U.S. financial institutions or non-U.S. entities, could be subject to a 30% withholding tax unless (a) the non-U.S. financial institution enters into an agreement with the IRS to provide to the IRS information concerning its direct and certain indirect U.S. account holders, or (b) in the case of other non-U.S. entities, such entity provides to the withholding agent similar information concerning its substantial U.S. beneficial owners. These rules do not apply with respect to payments from obligations that are outstanding as of March 18, 2012. You should consult your own tax advisors regarding the

treatment of U.S. withholding taxes in general and the application of the recently enacted legislation to your particular circumstances.

The disposition of our units on an established securities market by a non-U.S. Holder will not be subject to U.S. federal income tax, so long as (i) such non-U.S. Holder does not own (and is not deemed to own) more than 5% of our units, and (ii) for the calendar quarter during which such disposition occurs, our units are regularly quoted by brokers and dealers making a market in our units. Our Managing General Partner does not intend to list our units for trading on any exchange if such listing would adversely affect the tax consequences from disposing of the units as described above.

A non-U.S. Holder who holds more than 5% of our units may be subject to special rules under the Foreign Investment in Real Property Tax Act of 1980, or FIRPTA. For purposes of determining whether a non-U.S. Holder holds more than 5% of our units, special attribution rules apply. Where a non-U.S. person who holds (or is deemed to hold) more than 5% of our units disposes of units at a time when our partnership is a U.S. Real Property Holding Corporation, or USRPHC, (which determination includes a five year look back period) any gain will be subject to U.S. taxation at 35%, and such non-U.S. person will have a U.S. tax return filing obligation. Our Managing General Partner does not believe that our partnership is currently, or has been, a USRPHC. Our partnership is not under any obligation to avoid becoming a USRPHC or to notify unitholders in the event that our Managing General Partner determines it becomes a USRPHC. If any unitholder is a non-U.S. person and owns or anticipates owning more than 5% of our units, such person should consult their tax advisors. The application of the FIRPTA rules to a non-U.S. Holder who holds (or is deemed to hold) more than 5% of our units would result in such non-U.S. Holder being liable for FIRPTA tax if such non-U.S. Holder disposes of our units at a time when we are a USRPHC or have at any time been a USRPHC within the shorter of such non-U.S. Holder's holding period or five years preceding the disposition.

A non-U.S. tax-exempt entity generally could be subject to taxation in the United States on its U.S. source unrelated business taxable income and on certain trade or business income that is effectively connected with the conduct of any trade or business of our partnership or Brookfield Infrastructure in the United States. Our Managing General Partner and the Infrastructure General Partner intend 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 the conduct of a U.S. trade or business, but do expect our partnership and the Holding LP to realize some U.S. source investment income, which, if debt-financed, would constitute unrelated business taxable income. A non-U.S. tax-exempt entity should consult its own tax advisor to determine the U.S. federal income tax consequences with respect to an investment in our units.

The U.S. federal estate tax treatment of our units with regard to the estate of a non-citizen who is not a resident of the United States is not entirely clear. If our units are includable in the U.S. gross estate of such person, then a U.S. federal estate tax might be payable in connection with the death of such person. Individual non-U.S. Holders who are non-citizens and not residents of the United States should consult their own tax advisors concerning the potential U.S. federal estate tax consequences with regards to our units.

Our Managing General Partner will act as our partnership's "tax matters partner." As the tax matters partner, our Managing General Partner will have the authority, subject to certain restrictions, to act on our behalf in connection with any administrative or judicial review of our items of income, gain, loss, deduction or credit.

We have agreed to use commercially reasonable efforts to furnish to you, within 90 days after the close of each calendar year, tax information (including Schedule K-1), which describes on a U.S. dollar basis your share of our partnership's income, gain, loss and deduction for our preceding taxable year. In preparing this information, we will use various accounting and reporting conventions, some of which have been mentioned in the previous discussion, to determine your share of income, gain, loss and deduction. The IRS may successfully contend that certain of these reporting conventions are impermissible, which could result in an adjustment to your income or loss.

We may be audited by the IRS. Adjustments resulting from an IRS audit may require you to adjust a prior year's tax liability, and possibly may result in an audit of your own tax return. Any audit of your tax return could result in adjustments not related to our tax returns as well as those related to our tax returns.

U.S. persons having a financial interest in or signature authority over a financial account in a foreign country may be required to file annually with the IRS a "Report of Foreign Bank and Financial Accounts", or an FBAR. The IRS has recently issued guidance on the scope of the FBAR requirement. While individual stocks are not considered "financial accounts", commingled funds, such as mutual funds, are considered "financial accounts" for FBAR reporting purposes. As part of the recently issued guidance, the IRS requested comments on whether an ownership interest in a PFIC should create an FBAR filing requirement. It is not clear that an interest in our partnership will be considered an interest in a commingled fund requiring an FBAR, or that an ownership interest in a PFIC will create an FBAR reporting obligation. However, you are urged to consult your tax advisors regarding the applicability of any such reporting requirement.

If we were to engage in a "reportable transaction", we (and possibly you and others) would be required to make a detailed disclosure of the transaction to the IRS in accordance with recently issued regulations governing tax shelters and other potentially tax-motivated transactions. A transaction may be a reportable transaction based upon any of several factors, including the fact that it is a type of tax avoidance transaction publicly identified by the IRS as a "listed transaction", or as a "transaction of interest", or that it produces certain kinds of losses in excess of $2 million (or, in the case of certain foreign currency transactions, losses in excess of $50,000). An investment in us may be considered a "reportable transaction" if, for example, we recognize certain significant losses in the future. In certain circumstances, a unitholder who disposes of an interest in a transaction resulting in the recognition by such holder of significant losses in excess of certain threshold amounts may be obligated to disclose its participation in such transaction. Our participation in a reportable transaction also could increase the likelihood that our U.S. federal income tax information return (and possibly your tax return) would be audited by the IRS. Certain of these rules are currently unclear, and the scope of reportable transactions can change retroactively, and, therefore, it is possible that they may be applicable in situations other than significant loss transactions.

Moreover, if we were to participate in a reportable transaction with a significant purpose to avoid or evade tax, or in any listed transaction, you may be subject to (i) significant accuracy-related penalties with a broad scope, (ii) for those persons otherwise entitled to deduct interest on federal tax deficiencies, non-deductibility of interest on any resulting tax liability, and (iii) in the case of a listed transaction, an extended statute of limitations. We do not intend to participate in any reportable transaction with a significant purpose to avoid or evade tax, nor do we intend to participate in any listed transactions. However, no assurances can be made that the IRS will not assert that we have participated in such a transaction.

You should consult your own tax advisors concerning any possible disclosure obligation under the regulations governing tax shelters with respect to the disposition of our units held by you.

Our partnership currently intends to use the calendar year as its taxable year for U.S. federal income tax purposes. Under certain circumstances which we currently believe are unlikely to apply, a taxable year other than the calendar year may be required for such purposes.

Subject to the electing large partnership rules described below, 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 termination of our partnership would result in the close of its taxable year for all holders of our units. If you report on a taxable year other than a fiscal year ending on our partnership's year-end, and you are otherwise subject to U.S. federal income tax, the closing of our partnership's taxable year may result in more than 12 months of our partnership's taxable income or loss being includable in your taxable income for the year of termination. Our partnership would be required to make new tax elections after a termination, including a new Section 754 Election. A termination could also result in penalties and other adverse tax consequences if we were unable to determine that the termination had occurred. Moreover, a termination might either accelerate the application of, or subject us to, any tax legislation enacted before the termination.

The U.S. Internal Revenue Code allows large partnerships to elect streamlined procedures for income tax reporting. This election would reduce the number of items that must be separately stated on the Schedules K-1 that are issued to the holders of our units, and such Schedules K-1 would have to be provided to holders on or before the first March 15 following the close of each taxable year. In addition, this election would prevent our partnership from suffering a "technical termination" (which would close our taxable year and require that we make a new Section 754 Election) if, within a 12-month period, there is a sale or exchange of 50% or more of our total units. Despite the foregoing benefits, there are also costs and administrative burdens associated with such an election. Consequently, as of this time, our partnership has not elected to be subject to the reporting procedures applicable to large partnerships.

For each calendar year, we will report to you and to the IRS the amount of distributions that we pay, and the amount of tax (if any) that we withhold on these distributions. Under the backup withholding rules, you may be subject to backup withholding tax (at the applicable rate, currently 28%) with respect to distributions paid unless: (i) you are a corporation or come within another exempt category and demonstrate this fact when required or (ii) you provide a taxpayer identification number, certify as to no loss of exemption from backup withholding tax and otherwise comply with the applicable requirements of the backup withholding tax rules. If you are an exempt holder, you should indicate your exempt status on a properly completed IRS Form W-9. A Non-U.S. Holder may qualify as an exempt recipient by submitting a properly completed IRS Form W-8BEN. Backup withholding is not an additional tax; the amount of any backup withholding from a payment to you will be allowed as a credit against your U.S. federal income tax liability and may entitle you to a refund from the IRS.

If you do not timely provide us with IRS Form W-8, or W-9, as applicable, or such form is not properly completed, we may become subject to U.S. "backup" withholding taxes in excess of what

would have been imposed had our partnership received certifications from all investors. For administrative reasons, and in order to maintain fungibility of our units, such excess U.S. "backup" withholding taxes, and if necessary similar items, may be treated by our partnership as an expense that will be borne by all unitholders on a pro rata basis (e.g., since it may be impractical for us to allocate any such excess withholding tax cost to the unitholders that failed to timely provide the proper U.S. tax certifications). Additionally, under recently enacted U.S. legislation, certain payments of U.S. source income made after December 31, 2012, (including payments attributable to dispositions of property which produced (or could produce) certain U.S. source income) made to us or by us to or through non-U.S. financial institutions or non-U.S. entities, could be subject to a 30% withholding tax unless (a) the non-U.S. financial institution enters into an agreement with the IRS to provide to the IRS information concerning its direct and certain indirect U.S. account holders, or (b) in the case of other non-U.S. entities, such entity provides to the withholding agent similar information concerning its substantial U.S. beneficial owners. These rules do not apply with respect to payments from obligations that are outstanding as of March 18, 2012. You should consult your own tax advisors regarding the treatment of U.S. withholding taxes in general and the application of the recently enacted legislation to your particular circumstances.

Recently Enacted Legislation Affecting Disclosure Obligations for U.S. Individuals

United States legislation was enacted on March 18, 2010, that generally imposes new U.S. return disclosure obligations (and related penalties for failure to disclose) on U.S. individuals that hold certain specified foreign financial assets. The definition of specified foreign financial assets includes not only financial accounts maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution, any stock or security issued by a non-U.S. person, any financial instrument or contract held for investment that has an issuer or counterparty other than a U.S. person and any interest in a foreign entity. Unitholders are urged to consult their own tax advisors regarding the possible implications of this recently enacted legislation on their investment in the units.

Our partnership may allocate items of income, gain, loss, deduction and credit using a monthly or other convention, whereby any such items recognized in a given month by our partnership are allocated to our unitholders as of a specified date of such month. Any U.S. withholding taxes applicable to dividends received by Brookfield Infrastructure (and, in turn, our partnership) will generally be withheld by our partnership only when such dividends are paid. Because our partnership generally intends to distribute amounts received in respect of dividends shortly after receipt of such amounts, it is generally expected that any U.S. withholding taxes withheld by our partnership on such amounts will correspond to our unitholders who were allocated income and who received the distributions in respect of such amounts. Brookfield Infrastructure may invest in debt obligations or other securities for which the accrual of interest or income thereon is not matched by a contemporaneous receipt of cash. Any such accrued interest or other income would be allocated pursuant to the monthly convention described above. Consequently, our unitholders may recognize income in excess of cash distributions received from our partnership, and any income so included by a unitholder would increase the basis such unitholder has in our units and would offset any gain (or increase the amount of loss) realized by such unitholder on a subsequent disposition of its units. In addition, U.S. withholding taxes generally would be withheld by our partnership only on the payment of cash in respect of such accrued interest or other income, and, therefore, it is possible that some unitholders would be allocated income which may be distributed to a subsequent unitholder and such subsequent unitholder would be subject to withholding at the time of distribution. Consequently, the subsequent unitholder, and not the unitholder who was allocated income, would be entitled to claim any available credit with respect to such withholding.

Brookfield Infrastructure has invested and will continue to invest in certain Holding Entities and operating entities organized in non-U.S. jurisdictions, and income and gains from such investments may

be subject to withholding and other taxes in such jurisdictions. If any such non-U.S. taxes are imposed on income allocable to a U.S. Holder, and thereafter, such U.S. Holder disposed of its units prior to the date distributions are made in respect of such income, under applicable provisions of the U.S. Internal Revenue Code and U.S. Treasury Regulations, our unitholder to whom such income was allocated (and not our unitholder to whom distributions were ultimately made) would, subject to other applicable limitations, be the party permitted to claim a credit for such non-U.S. taxes for U.S. federal income tax purposes. Complex rules may, depending on a unitholder's particular circumstances, limit the availability or use of foreign tax credits, and investors are urged to consult their own tax advisors regarding all aspects of foreign tax credits.

Persons who hold an interest in our partnership as a nominee for another person are required to furnish to us:

Brokers and financial institutions are required to furnish additional information, including whether they are U.S. persons and specific information on units they acquire, hold or transfer for their own account. A penalty of $50 per failure, up to a maximum of $100,000 per calendar year, is imposed by the U.S. Internal Revenue Code for failure to report that information to us. The nominee is required to supply the beneficial owner of our units with the information furnished to us.

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. You should be aware that the U.S. federal income tax rules, particularly those applicable to partnerships, are constantly under review (including currently) by the Congressional tax-writing committees and other persons involved in the legislative process, the IRS, the U.S. Treasury Department, and the courts, frequently resulting in revised interpretations of established concepts, statutory changes, revisions to regulations and other modifications and interpretations, any of which could adversely affect the value of our units and be effective on a retroactive basis. For example, changes to the U.S. federal tax laws and interpretations thereof could adversely affect the U.S. federal income tax treatment of publicly traded partnerships, including changes that make it more difficult or impossible for our partnership (or Brookfield Infrastructure) to meet the Qualifying Income Exception so as to be treated as a partnership for U.S. federal income tax purposes that is not taxable as a corporation, changes that recharacterize a partner's share of capital gain, "qualified dividend" income as ordinary income, and possible other changes in characterization of certain U.S. source income for non-U.S. partners, with potential withholding tax consequences and adverse federal income tax consequences, and changes that reduce the net amount of distributions available to our unitholders. (See, for example, the discussion of certain potential implications of President Obama's fiscal year 2012 budget proposal under Item 10.E

"Taxation—Certain Material U.S. Tax Considerations—Partnership Status of our partnership and the Holding LP," above.) Such changes could also affect or cause us to change the way we conduct our activities, affect the tax considerations of an investment in our partnership, change the character or treatment of portions of our partnership's income (including changes that recharacterize certain allocations as potentially non-deductible fees) and adversely affect an investment in our units.

Our partnership's organizational documents and agreements permit our Managing General Partner to modify our limited partnership agreement from, time-to-time, without the consent of our unitholders, to address certain changes in U.S. federal income tax regulations, legislation or interpretation or to elect to treat our partnership as a corporation for U.S. tax purposes. In some circumstances, such revisions could have a material adverse impact on some or all of our unitholders.

THE FOREGOING DISCUSSION IS NOT INTENDED AS A SUBSTITUTE FOR CAREFUL TAX PLANNING. THE TAX MATTERS RELATING TO US AND OUR UNITHOLDERS ARE COMPLEX AND ARE SUBJECT TO VARYING INTERPRETATIONS. MOREOVER, THE EFFECT OF EXISTING INCOME TAX LAWS, THE MEANING AND IMPACT OF WHICH IS UNCERTAIN AND OF PROPOSED CHANGES IN INCOME TAX LAWS WILL VARY WITH THE PARTICULAR CIRCUMSTANCES OF EACH UNITHOLDER AND IN REVIEWING THIS ANNUAL REPORT ON FORM 20-F THESE MATTERS SHOULD BE CONSIDERED. UNITHOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE U.S. FEDERAL, STATE, LOCAL AND OTHER TAX CONSEQUENCES OF ANY INVESTMENT IN OUR UNITS.

The following is a fair summary of the principal Canadian federal income tax consequences of the holding and disposition of units in our partnership generally applicable to a holder who, for purposes of the Tax Act and at all relevant times, holds our units as capital property and deals at arm's length and is not affiliated with our partnership, Brookfield Infrastructure, the Managing General Partner, the Infrastructure General Partner, the Infrastructure GP LP and their respective affiliates. Generally, our units will be considered to be capital property to a holder, provided that the holder does not hold our units in the course of carrying on a business of trading or dealing in securities and has not acquired them in one or more transactions considered to be an adventure in the nature of trade.

This summary is not applicable to (i) a holder that is a "financial institution" as defined in the Tax Act for purposes of the "mark-to-market" rules, (ii) a holder that is a "specified financial institution" as defined in the Tax Act, (iii) a holder who makes or has made a functional currency reporting election pursuant to section 261 of the Tax Act, or (iv) a holder an interest in which would be a "tax shelter investment" as defined in the Tax Act, or who acquires a unit as a tax shelter investment (and this summary assumes that no such persons hold our units). Any such holders should consult their own tax advisors with respect to an investment in our units.

This summary is based on the current provisions of the Tax Act, the regulations thereunder, or the Regulations, all specific proposals to amend the Tax Act or the Regulations publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof, or the Tax Proposals, and the current published administrative and assessing policies and practices of the CRA. This summary assumes that all Tax Proposals will be enacted in the form proposed but no assurance can be given that the Tax Proposal will be enacted in the form proposed or at all. This summary does not otherwise take into account or anticipate any changes in law, whether by judicial, administrative or legislative decision or action or changes in CRA's administrative and assessing policies and practices, nor does it take into account provincial, territorial or foreign income tax legislation or considerations, which may differ from those described herein. This summary is not exhaustive of all possible Canadian federal income tax consequences that may affect holders and prospective holders.

This summary assumes that neither our partnership nor Brookfield Infrastructure will be considered to carry on business in Canada. Our Managing General Partner and the Infrastructure General Partner have advised that they intend to conduct the affairs of each of these entities, to the extent possible, so that none of these entities should be considered to carry on business in Canada for purposes of the Tax Act. However, no assurance can be given in this regard.

This summary also assumes that neither our partnership nor Brookfield Infrastructure is a "tax shelter" or "tax shelter investment", each as defined in the Tax Act. However, no assurance can be given in this regard.

This summary also assumes that neither our partnership nor Brookfield Infrastructure will be a "SIFT partnership" as defined in subsection 197(1) of the Tax Act at any relevant time for purposes of the SIFT Rules on the basis that neither our partnership nor Brookfield Infrastructure will be a "Canadian resident partnership" as defined in subsection 248(1) of the Tax Act at any relevant time. However, there can be no assurance that the SIFT Rules will not be revised or amended such that the SIFT Rules will apply.

This summary is of a general nature only and is not intended to be, nor should it be construed to be, legal or tax advice to any particular holder of our units, and no representation with respect to the Canadian federal income tax consequences to any particular holder is made. Consequently, holders of our units and prospective holders of our units are advised to consult their own tax advisors with respect to their particular circumstances. See also "Risk Factors—Risks Relating to Taxation".

The following is a discussion of the consequences under the Tax Act to holders who at all relevant times are resident or deemed to be resident in Canada under the Tax Act, or Canadian Limited Partners.

Each Canadian Limited Partner is required to include (or, subject to the "at-risk rules" discussed below, entitled to deduct) in computing his or her income for a particular taxation year the Canadian Limited Partner's pro rata share of the income (or loss) of our partnership for its fiscal year ending in, or coincidentally with, the Canadian Limited Partner's taxation year end, whether or not any of that income is distributed to the Canadian Limited Partner in the taxation year and regardless of whether our units were held throughout such year.

Our partnership will not itself be a taxable entity and is not expected to be required to file an income tax return in Canada. However, the income (or loss) of our partnership for a fiscal period for purposes of the Tax Act will be computed as if it were a separate person resident in Canada and our partners will be allocated a share of that income (or loss) in accordance with our limited partnership agreement. The income (or loss) of our partnership will include our share of the income (or loss) of Brookfield Infrastructure for a fiscal year determined in accordance with the Holding LP's limited partnership agreement. For this purpose, our partnership's fiscal year end and that of Brookfield Infrastructure will be December 31.

The income for tax purposes of our partnership for a given fiscal year of our partnership will be allocated to each unitholder in an amount calculated by multiplying such income that is allocable to unitholders by a fraction, the numerator of which is the sum of the distributions received by such unitholder with respect to such fiscal year and the denominator of which is the aggregate amount of the distributions made by our partnership to unitholders with respect to such fiscal year. Generally, the source and character of items of income allocated to a unitholder with respect to a fiscal year of our partnership will be the same source and character as the cash distributions received by such unitholder with respect to such fiscal year.

If, with respect to a given fiscal year, no distribution is made by our partnership to unitholders or our partnership has a loss for tax purposes, one quarter of the income, or loss, as the case may be, for tax purposes of our partnership for such fiscal year that is allocable to unitholders, will be allocated to the unitholders of record at the end of each calendar quarter ending in such fiscal year in the proportion that the number of units held at each such date by a unitholder is of the total number of units that are issued and outstanding at each such date. Generally, the source and character of such income or loss allocated to a unitholder at the end of each calendar quarter will be the same source and character as the income or loss earned or incurred by our partnership in such calendar quarter.

The income of our partnership as determined for purposes of the Tax Act may differ from its income as determined for accounting purposes and may not be matched by cash distributions. In addition, for purposes of the Tax Act, all income of our partnership and the Holding LP must be calculated in Canadian currency. Where our partnership (or Brookfield Infrastructure) holds investments denominated in U.S. dollars or other foreign currencies, gains and losses may be realized by our partnership as a consequence of fluctuations in the relative values of the Canadian and foreign currencies.

In computing the income (or loss) of our partnership, deductions may be claimed in respect of reasonable administrative costs, interest and other expenses incurred by our partnership for the purpose of earning income, subject to the relevant provisions of the Tax Act. Our partnership may also deduct from its income for the year a portion of the reasonable expenses, if any, incurred by our partnership to issue units. The portion of such issue expenses deductible by our partnership in a taxation year is 20% of such issue expenses, pro-rated where our partnership's taxation year is less than 365 days. Our partnership and the Holding LP may be required to withhold and remit Canadian federal withholding tax on any management or administration fees or charges paid or credited to a non-resident person, to the extent that such management or administration fees or charges are deductible in computing our partnership's or the Holding LP's income from a source in Canada.

In general, a Canadian Limited Partner's share of any income (or loss) from our partnership from a particular source will be treated as if it were income (or loss) of the Canadian Limited Partner from that source, and any provisions of the Tax Act applicable to that type of income (or loss) will apply to the Canadian Limited Partner. Our partnership will invest in limited partnership units of Brookfield Infrastructure. In computing our partnership's income (or loss) under the Tax Act, Brookfield Infrastructure will itself be deemed to be a separate person resident in Canada which computes its income (or loss) and allocates to its partners their respective share of such income (or loss). Accordingly, the source and character of amounts included in (or deducted from) the income of Canadian Limited Partners on account of income (or loss) earned by Brookfield Infrastructure generally will be determined by reference to the source and character of such amounts when earned by Brookfield Infrastructure.

The characterization by CRA of gains realized by our partnership or Brookfield Infrastructure on the disposition of investments as either capital gains or income gains will depend largely on factual considerations, and no conclusions are expressed herein.

A Canadian Limited Partner's share of taxable dividends received or considered to be received by our partnership in a fiscal year from a corporation resident in Canada will be treated as a dividend received by the Canadian Limited Partner and will be subject to the normal rules in the Tax Act applicable to such dividends, including the enhanced dividend gross up and tax credit for eligible dividends when the dividend received by Brookfield Infrastructure is designated as an eligible dividend.

Foreign taxes paid by our partnership or Brookfield Infrastructure and taxes withheld at source (other than for the account of a particular Canadian Limited Partner) will be allocated pursuant to the governing partnership agreement. Each Canadian Limited Partner's share of the business-income tax and non-business-income tax paid in a foreign country for a year will be creditable against its Canadian

federal income tax liability to the extent permitted by the detailed rules contained in the Tax Act. Although the foreign tax credit provisions are designed to avoid double taxation, the maximum credit is limited. Because of this, and because of timing differences in recognition of expenses and income and other factors, there is a risk of double taxation.

Our partnership and the Holding LP will be deemed to be a non-resident person in respect of certain amounts 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 exempt from Canadian federal withholding tax) paid by a person resident or deemed to be resident in Canada to Brookfield Infrastructure 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-resident partners may be entitled to under an applicable income treaty or convention, provided that the residency status and entitlement to the treaty benefits can be established. In determining the rate of Canadian federal withholding tax applicable to amounts paid by the Holding Entities to Brookfield Infrastructure, we expect the Holding Entities to look-through Brookfield Infrastructure and our partnership to the residency of the partners of our partnership (including partners who are residents of Canada) and to take into account any reduced rates of Canadian federal withholding tax that non-resident 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 Brookfield Infrastructure. However, there can be no assurance that CRA would apply its administrative practice in this context. Under the Canada-U.S. Tax Treaty, a Canadian resident payer may be required to look-through fiscally transparent partnerships such as our partnership and the Holding LP to the residency of limited partners of the partnership who are entitled to relief under that treaty and take into account reduced rates of Canadian federal withholding tax that such limited partners may be entitled to under that treaty.

If our partnership incurs losses for tax purposes, each Canadian Limited Partner will, subject to the REOP Proposals discussed below, be entitled to deduct in the computation of income for tax purposes the Canadian Limited Partner's pro rata share of any net losses for tax purposes of our partnership for its fiscal year to the extent that the Canadian Limited Partner's investment is "at-risk" within the meaning of the Tax Act. The Tax Act contains "at-risk rules" which may, in certain circumstances, restrict the deduction of a limited partner's share of any losses of a limited partnership. Our Managing General Partner and the Infrastructure General Partner do not anticipate that our partnership or Brookfield Infrastructure will incur losses but no assurance can be given in this regard. Accordingly, Canadian Limited Partners should consult their own tax advisors for specific advice with respect to the potential application of the "at-risk rules".

On October 31, 2003, the Department of Finance released the REOP Proposals for public comment. Under the REOP Proposals, a taxpayer would be considered to have a loss from a source that is a business or property for a taxation year only if, in that year, it is reasonable to assume that the taxpayer will realize a cumulative profit (excluding capital gains or losses) from the business or property during the period that the business is carried on or that the property is held. In general, these proposals may deny the realization of losses by Canadian Limited Partners from their investment in our partnership in a particular taxation year, if, in the year the loss is claimed, it is not reasonable to expect that an overall cumulative profit would be earned from the investment in our partnership for the period in which the Canadian Limited Partner has held and can reasonably be expected to hold the investment. Our Managing General Partner and the Infrastructure General Partner do not anticipate that the activities of our partnership and the Holding LP will, in and of themselves, generate losses, but no assurance can be given in this regard. However, unitholders may incur expenses in connection with

an acquisition of units in our partnership that could result in a loss that could be affected by the REOP Proposals. The REOP Proposals have been the subject of a number of submissions to the Minister of Finance (Canada). As part of the 2005 federal budget, the Minister of Finance (Canada) announced that an alternative proposal to reflect the REOP Proposals would be released for comment at an early opportunity. No such alternative proposal has been released to date. There can be no assurance that such alternative proposal will not adversely affect Canadian Limited Partners, or that any revised proposals may not differ significantly from the REOP Proposals described herein.

On March 4, 2010, the Minister of Finance (Canada) announced as part of the 2010 Canadian Federal Budget that the outstanding Tax Proposals regarding investments in "foreign investment entities" would be replaced with revised Tax Proposals under which the existing rules in section 94.1 of the Tax Act relating to investments in "offshore investment fund property" would remain in place subject to certain limited enhancements. The Minister of Finance (Canada) released draft legislation to implement the revised Tax Proposals on August 27, 2010. Existing section 94.1 of the Tax Act contains rules relating to investments in non-resident entities that could in certain circumstances cause income to be imputed to Canadian Limited Partners, either directly or by way of allocation of such income imputed to our partnership or to Brookfield Infrastructure. These rules would apply if it is reasonable to conclude, having regard to all the circumstances, that one of the main reasons for the Canadian Limited Partner, our partnership or Brookfield Infrastructure acquiring or holding an investment in a non-resident entity is to derive a benefit from portfolio investments in such a manner that taxes under the Tax Act on income, profits and gains for any year are significantly less than they would have been if such income, profits and gains had been earned directly. In determining whether this is the case, existing section 94.1 of the Tax Act as proposed to be amended provides that consideration must be given to, among other factors, the extent to which the income, profits and gains for any fiscal period are distributed in that or the immediately following fiscal period. If, having regard to the particular circumstances, it is reasonable to conclude that one of the main reasons for the acquisition or holding of our units by the Canadian Limited Partner, of units of Brookfield Infrastructure by our partnership, or of interests in non-resident entities (other than a controlled foreign affiliate as defined in the Tax Act, or CFA) by Brookfield Infrastructure, is as stated above, income will be imputed directly to the Canadian Limited Partner or to our partnership or Brookfield Infrastructure and allocated to the Canadian Limited Partner in accordance with the rules in existing section 94.1 of the Tax Act as proposed to be amended. There can be no assurance that the revised Tax Proposals will be enacted as proposed or at all. The rules in section 94.1 of the Tax Act are complex and Canadian Limited Partners should consult their own tax advisors regarding the application these rules to them in their particular circumstances.

Dividends paid by the CFAs to Brookfield Infrastructure will be included in computing the income of Brookfield Infrastructure. To the extent that any of the CFAs or any direct or indirect subsidiary thereof earns income that is characterized as FAPI, in a particular taxation year of the CFA, the FAPI allocable to Brookfield Infrastructure must be included in computing the income of Brookfield Infrastructure for Canadian federal income tax purposes for the fiscal period of Brookfield Infrastructure in which the taxation year of that CFA ends, whether or not Brookfield Infrastructure actually receives a distribution of that FAPI. If an amount of FAPI is included in computing the income of Brookfield Infrastructure for Canadian federal income tax purposes, an amount may be deductible in respect of the "foreign accrual tax" as defined in the Tax Act applicable to the FAPI. Any amount of FAPI included in income net of the amount of any deduction in respect of foreign accrual tax will increase the adjusted cost base to Brookfield Infrastructure of its shares of the particular CFA in respect of which the FAPI was included. At such time as Brookfield Infrastructure receives a dividend of this type of income that was previously treated as FAPI, that dividend will effectively not be taxable to Brookfield Infrastructure and there will be a corresponding reduction in the adjusted cost base to Brookfield Infrastructure of the particular CFA shares.

The disposition by a Canadian Limited Partner of a unit of our partnership will result in the realization of a capital gain (or capital loss) by such limited partner. The amount of such capital gain (or capital loss) will generally be the amount, if any, by which the proceeds of disposition of a unit, less any reasonable costs of disposition, exceed (or are exceeded by) the adjusted cost base of such unit. In general, the adjusted cost base of a Canadian Limited Partner's units will be equal to: (i) the actual cost of the units (excluding any portion thereof financed with limited recourse indebtedness); plus (ii) the pro rata share of the income of our partnership allocated to the Canadian Limited Partner for the fiscal years of our partnership ending before the relevant time; less (iii) the aggregate of the pro rata share of losses of our partnership allocated to the Canadian Limited Partner (other than losses which cannot be deducted because they exceed the Canadian Limited Partner's "at-risk" amount) for the fiscal years of our partnership ending before the relevant time; and less (iv) the Canadian Limited Partner's distributions from our partnership made before the relevant time. The adjusted cost base of each of our units will be subject to the averaging provisions contained in the Tax Act.

Where a Canadian Limited Partner disposes of all of its units, such person will no longer be a partner of our partnership. If, however, a Canadian Limited Partner is entitled to receive a distribution from our partnership after the disposition of all such units, then the Canadian Limited Partner will be deemed to dispose of the units at the later of: (i) the end of the fiscal year of our partnership during which the disposition occurred; and (ii) the date of the last distribution made by our partnership to which the Canadian Limited Partner was entitled. Pursuant to the Tax Proposals, the pro rata share of the income (or loss) for tax purposes of our partnership for a particular fiscal year which is allocated to a Canadian Limited Partner who has ceased to be a partner will generally be added (or deducted) in the computation of the adjusted cost base of the Canadian Limited Partner's units at the time of the disposition. These rules are complex and Canadian Limited Partners should consult their own tax advisors for advice with respect to the specific tax consequences to them of disposing of units of our partnership.

A Canadian Limited Partner will realize a deemed capital gain if, and to the extent that, the adjusted cost base of the Canadian Limited Partner's units is negative at the end of any fiscal year of our partnership. In such a case, the adjusted cost base of the Canadian Limited Partner's units will be nil at the beginning of the next fiscal year of our partnership.

In general, one-half of a capital gain realized by a Canadian Limited Partner must be included in computing such limited partner's income as a taxable capital gain. One-half of a capital loss is deducted as an allowable capital loss against taxable capital gains realized in the year and any remainder may be deducted against taxable capital gains in any of the three years preceding the year or any year following the year to the extent and under the circumstances described in the Tax Act.

Where a Canadian Limited Partner disposes of units to a tax-exempt person, more than one-half of such capital gain may be treated as a taxable capital gain if any portion of the gain is attributable to an increase in value of depreciable property held by Brookfield Infrastructure. Canadian Limited Partners contemplating such dispositions should consult their own tax advisors. The Infrastructure General Partner has advised that it does not expect that Brookfield Infrastructure will hold any depreciable property and therefore expects that only one-half of any capital gains arising from a disposition of our units should be treated as taxable capital gains.

A Canadian Limited Partner that is throughout the relevant taxation year a "Canadian-controlled private corporation" as defined in the Tax Act may be liable to pay an additional refundable tax of 6²/3% on its "aggregate investment income", as defined in the Tax Act, for the year, which is defined to include taxable capital gains.

Provided that our units are listed on a designated stock exchange under the Tax Act (which includes the TSX and the NYSE), our units will be "qualified investments" under the Tax Act for a trust governed by a registered retirement saving plan, deferred profit sharing plan, registered retirement income fund, registered education saving plan, registered disability saving plan, and a tax-free savings account. 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 registered plans and certain other taxpayers and with respect to the acquisition or holding of prohibited investments by a tax-free savings account.

The following summary applies to holders who at all relevant times are not resident and are not deemed to be resident in Canada for purposes of the Tax Act and who do not acquire or hold their investment in our partnership in connection with a business carried on, or deemed to be carried on, in Canada, each a Non-Canadian Limited Partner. The following summary assumes that our units are not "taxable Canadian property" as defined in the Tax Act and that our partnership and the Holding LP generally will not dispose of properties that are taxable Canadian property (which includes, but is not limited to, property that is used or held in a business carried on in Canada, shares of corporations resident in Canada that are not listed on a designated stock exchange and listed shares where the number of shares owned exceeds prescribed amounts). Our units will be taxable Canadian property if, at any time within the 60-month period ending at the time of disposition or deemed disposition, more than 50% of the fair market value of our units was derived, directly or indirectly, from one or any combination of (i) real or immovable property situated in Canada, (ii) Canadian resource properties, (iii) timber resource properties, and (iv) options in respect of or interests or civil law rights in such property. Our Managing General Partner and the Infrastructure General Partner advise that our units are not expected to be taxable Canadian property and that our partnership and the Holding LP are not expected to dispose of taxable Canadian property. However, no assurance can be given in this regard.

A Non-Canadian Limited Partner will not be subject to Canadian federal income tax under Part I of the Tax Act on its share of income from a business carried on by our partnership (or Brookfield Infrastructure) outside Canada or the non-business income earned by our partnership (or Brookfield Infrastructure) from sources in Canada. However, a Non-Canadian Limited Partner may be subject to Canadian federal withholding tax under Part XIII of the Tax Act, as described below. Our Managing General Partner and the Infrastructure General Partner, as the case may be, have advised that they intend to organize and conduct the affairs of our partnership or Brookfield Infrastructure such that Non-Canadian Limited Partners should not be considered to be carrying on business in Canada solely by virtue of their investment in our partnership. However, no assurance can be given in this regard.

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-resident partners may be entitled to under an applicable income tax treaty or convention, provided that the residency status and entitlement to the treaty benefits can be established. In determining the rate of Canadian federal withholding tax applicable to amounts paid by the Holding Entities to Brookfield Infrastructure, we expect the Holding Entities to look-through Brookfield Infrastructure and our partnership to the residency of the partners of our partnership (including partners who are residents of Canada) and to take into account any reduced rates of Canadian federal withholding tax that non-resident 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 Brookfield Infrastructure. However, there can be no assurance that the CRA would apply its administrative practice in this context. Under the Canada-U.S. Tax Treaty, a Canadian resident payer may be required to look through fiscally transparent partnerships such as our partnership and the Holding LP to the residency of limited partners of our partnership who are entitled to relief under the treaty and take into account reduced rates of Canadian federal withholding tax that such limited partners may be entitled to under that treaty.

Set out below is general Australian income tax implications for Australian tax resident holders of the Partnership units (Australian Holders).

This is not tax advice an Australian Holder can rely on. The individual circumstances of each Australian Holder will affect the taxation implications of each Australian Holder's interest in the Partnership. Australian Holders should seek appropriate independent professional advice that considers the taxation implications in respect of their own specific circumstances.

The discussion is primarily intended for Australian Holders who hold their interest in the Partnership on capital account. Different outcomes will potentially arise for Australian Holders who are investing on revenue account. Those Australian Holders seek professional taxation advice in relation to their interest in the Partnership.

The summary of the Australian income tax implications set out below is based on established judicial and administrative interpretations of the Income Tax Assessment Act 1997 (Cth) (the ITAA 1997), the Income Tax Assessment Act 1936 (Cth) (the ITAA 1936) and the Taxation Administration Act 1953 (Cth) (the Administration Act) as at the date of this Opinion.

The key Australian income tax implications for Australian Holders of Partnership Units are set out below:

The Partnership should be classified as a 'corporate limited partnership' for Australian income tax purposes as:

On the basis that the Partnership is a corporate limited partnership it should be treated as a company for Australian tax purposes.

The Partnership is a non-resident of Australia for tax purposes and therefore, should not be subject to income tax in Australia except for any income sourced in Australia, or in respect of certain capital gains that relate to 'taxable Australian property' as detailed in the ITAA 1997.

Distributions made by the Partnership to Australian Holders should be characterised as dividends for Australian income tax purposes and included in Australian Holders' assessable unfranked income.

Australian Holders should not be subject to income tax on an accruals basis under the Controlled Foreign Company (CFC) or proposed Foreign Accumulation Fund (FAF) rules. This conclusion is dependent on the quantum and nature of the interests held in the Partnership.

The disposal of Partnership Units by Australian Holders should give rise to a capital gains tax (CGT) event for the Australian Holders. Broadly, Australian Holders that hold their units on capital account should realise a capital gain, or loss, equal to the difference between any capital proceeds received and the cost base of the Partnership Units.

There is no requirement as to where or under which law the liability is limited. For tax purposes, the liability is limited if it is effectively limited under the laws applying to the partnership (as per the partnership agreement).

Article 7 of the Amended and Restated Limited Partnership Agreement of the Partnership (the Partnership Agreement) provides "the Limited Partners shall have no liability under this Agreement except as expressly provided in this Agreement or the Limited Partnership Act or the Exempted Partnerships Act". Accordingly, the Partnership should be a limited partnership for Australian tax purposes.

Under subsection 94D(1)(a) of the ITAA 1936, a partnership will be a corporate limited partnership in relation to the year of income of the partnership if the year of income is the 1995-96 year of income or a later year of income.

The Partnership should be a corporate limited partnership under subsection 94D(1) of the above definition. Subsection 94D(2) of the ITAA 1936 specifically excludes from a corporate limited partnership a Venture Capital Limited Partnership (VCLP), Early Stage Venture Capital Limited Partnership (ESVCLP), or Australian Venture Capital Fund or Funds (AFOF). A requirement for each of these definitions is that the partnership be registered either in Australia or a country prescribed by relevant regulations or be an Australian resident. The Partnership is registered in Bermuda and is not a

resident of Australia. Bermuda is not a country prescribed by relevant regulations. Therefore the partnership will not be a SCLP, ESVCLP or AFOF. A VCLP is defined by reference to the Venture Capital Act 2002. The Partnership, as a Bermudan Exempted Limited Partnership, will not be excluded from the definition of a corporate limited partnership as subsection 9-1(1) of the Venture Capital Act requires of a VCLP that:

Pursuant to sub-section 94D(5) of the ITAA 1936 an exception to the Partnership being a corporate limited partnership applies if it is a 'foreign hybrid limited partnership' (FHLP) as defined in section 830-10 of the ITAA 1997. A limited partnership will be a FHLP if:

Paragraph (a) should be met on the basis that the Partnership was formed in Bermuda. Paragraph (b) would not be met on the basis that Bermuda does not impose any tax on income, profits, dividends or wealth. Therefore, there is no foreign tax imposed under the laws of Bermuda on the partners of the Partnership and this paragraph will not be satisfied. This position is confirmed by the Australia Taxation Office (ATO) in ATO ID 2006/149. On the basis that paragraph (b) is not met the Partnership should not be a FHLP.

The Partnership should be classified as a corporate limited partnership for Australian income tax purposes in accordance with section 94D of the ITAA 1997. The consequences of that include that the Partnership is treated as a company for the purposes of applying Australian domestic income tax law (sections 94J and 94K of the ITAA 1936). Accordingly, Australian Holders' units in the Partnership should be treated as shares in a company.

Australia's Foreign Investment Fund (FIF) rules which apply to Australian residents with non-controlling shareholdings in foreign companies have been repealed and are being replaced. Exposure Draft legislation was released on 28 April 2010 for an anti-roll up fund rule that will apply to certain offshore investments.

The Foreign Accumulation Fund (FAF) rules are proposed to apply effective from 1 July 2010. Broadly, the FAF rules apply to an Australian resident who has an interest in a FAF, providing a tax deferral benefit for the income year. A FAF is a foreign resident that is not a CFC, whose investment returns are subject to a low level of risk and which does not distribute substantially all of the profits and gains of the fund.

The level of risk of return of an investment held by an entity will be low if the return is 'sufficiently certain'. A return is sufficiently certain, where at the time the investment is made it is reasonably expected that the foreign entity will receive returns from the investments it makes and at least some of the return is fixed or determinable with reasonable accuracy.

Returns on an investment in the Partnership will not be fixed or accurately determinable as the distributions are at the discretion of the Managing General Partner. The Managing General Partner is not required to make distributions and provides no assurance that distributions will be made as intended. The distributions paid by the Partnership will be dependent on the performance of its investments. Accordingly, the FAF rules should not apply to the income accruing to Australian Holders in the Partnership.

Australian Holders will potentially receive distributions from the Partnership. Distributions will be treated as dividends on the basis that the Partnership is a corporate limited partnership for Australian tax purposes. The distributions should be treated as unfranked dividends to Australian Holders.

The Partnership will not provide information to enable Australian Holders to determine whether a return of capital has been made for Australian tax purposes. Therefore, Australian Holders should treat all distributions as unfranked dividends.

The taxation treatment of a Partnership dividend received by Australian Holders will vary depending on the type of Australian Holder. Australian Holders should seek further independent advice in relation to the nature of future distributions received from the Partnership.

Set out below is a summary of how different types of Australian Holders should treat a distribution received from the Partnership.

Distributions received by Australian tax resident individuals should in most cases be included in their Australian assessable income. Australian Holders should be entitled to an Australian foreign income tax offset which reduces the Australian tax payable on assessable dividends by the amount of any foreign income tax withheld by the Partnership.

Australian Holders should seek independent advice in relation to their entitlement to Australian foreign income tax offsets to the extent foreign tax is withheld.

The taxation treatment of a dividend received by an Australian tax resident company is the same as that described above for an Australian tax resident individual.

The comments below relate to Australian tax resident beneficiaries who are not under a legal disability where those beneficiaries are presently entitled to income of an Australian resident trust. If the beneficiary is under a legal disability, we recommend those beneficiaries seek independent professional taxation advice.

Distributions in the form of dividend income should either be included in the trustee's, or the beneficiary's, assessable income, as the case may be. The tax treatment of the dividend then depends on the legal identity of the beneficiary as an individual, a company or a trust (refer to comments above).

Dividends paid to an Australian tax resident superannuation fund should be included in the fund's Australian assessable income. Superannuation funds should be entitled to an Australian foreign income tax offset against the Australian tax payable on assessable dividends for any foreign income tax withheld by the Partnership on future distributions.

Australian Holders should seek further independent advice in relation to their entitlement to Australian foreign income tax offsets to the extent foreign tax is withheld on the Partnership distributions.

Australian Holders with income tax years that end on 30 June will not receive any documentation from the Partnership that will correlate directly to a 30 June income tax year end. Australian Holders will need to rely on distribution payment statements to support their Australian income tax disclosures.

The cost base of the Partnership Units for Australian Holders who bought their units in the Partnership directly should equal the money paid for those units plus any incidental costs of acquisition and disposal of the Partnership Units (e.g. broker's fees, borrowing expenses).

Where an Australian Holder received the Partnership Units as consideration for entering into the Merger Transaction, the cost base or reduced cost base of the Partnership Units acquired is made up of a number of elements including the money paid or market value of property given to acquire the Partnership Units. That amount should be the market value of the Prime Infrastructure Securities exchanged for the Partnership Units under the Merger Transaction plus the incidental costs of acquisition and disposal of the Prime Infrastructure Securities (if any).

On the basis that the Partnership and the Prime Infrastructure Securityholders were acting at arm's length, the market value of the Prime Infrastructure Securities disposed of under the Merger Transaction should be the same as the market value of the Partnership Units received in exchange.

The acquisition date for the Partnership Units for CGT purposes should be the date the Partnership Units were allotted to the Prime Infrastructure Securityholders (8 December 2010 Australian Eastern Standard Time).

The market value of the Partnership Units may be determined by reference to the NYSE/TSX VWAP of these Units on 8 December 2010 (AU$20.651 per Unit).

In the event Australian Holders dispose of Partnership Units, a capital gain should arise where the sale proceeds received exceed an Australian Holders' cost base in the Partnership Units. A capital loss should arise where the Australian Holders' reduced cost base exceeds the sale proceeds. The time that the CGT event occurs is when the contract is entered into or, if there is no contract, when the change of ownership occurs.

Partnership distributions should be treated as unfranked dividends and no CGT cost base reduction should be calculated as a result of the distributions.

Where the proceeds received are in foreign currency (e.g. US$ or CA$), these should be converted into A$ at the daily average exchange rate for the day of the sale (the date the sale contract is entered into). The ATO publish daily average exchange rates on their website (www.ato.gov.au). This may be a different amount than the A$ cash an Australian Holder ultimately receives.

Accordingly, there may a foreign exchange gain or loss if there are any fluctuations in the exchange rate between the date of the sale contract and the date payment is received by the Australian Holders. To the extent payment is received within 12 months of the date of disposal (the date the sale contract is entered into) of the Partnership Units any such foreign exchange realisation gains or losses will be capital in nature and subject to the CGT provisions (i.e. included in the overall gain or loss on the disposal of the Partnership Units).

If payment is received more than 12 months after the contract date, the foreign exchange gain or loss provisions of the ITAA 1997 apply. Australian Holders should seek specific advice in this circumstance.

Provided the Partnership Units that gave rise to the capital gain were held for at least 12 months prior to the occurrence of the CGT event, any net capital gain realised by a Australian Holder on those Partnership Units (e.g. if a sale were to occur) may qualify for discount capital gains tax treatment.

The discount is taken into account after applying any available capital losses against the capital gain eligible for the discount.

This treatment broadly only applies in respect of Partnership Units held by Australian Holders that are individuals, trustees of trusts, and trustees of superannuation funds. No such discount is available for corporate Australian Holders.

Where the CGT discount is available, individual Australian Holders either holding their Partnership Units directly or indirectly through a trust) may reduce their net capital gain by 50%. For trustees (responsible entities) of superannuation funds, the net capital gain may be reduced by 33¹/3%.

In Bermuda there are no taxes on profits, income or dividends, nor is there any capital gains tax, estate duty or death duty. Profits can be accumulated and it is not obligatory to pay dividends. As "exempted undertakings", exempted partnerships and overseas partnerships are entitled to apply for (and will ordinarily receive) an assurance pursuant to the Exempted Undertakings Tax Protection Act 1966 that, in the event that legislation introducing taxes computed on profits or income, or computed on any capital asset, gain or appreciation, is enacted, such taxes shall not be applicable to the partnership or any of its operations until March 28, 2016. Such an assurance may include the assurance that any tax in the nature of estate duty or inheritance tax shall not be applicable to the units, debentures or other obligations of the partnership.

Exempted partnerships and overseas partnerships fall within the definition of "international businesses" for the purposes of the Stamp Duties (International Businesses Relief) Act 1990, which means that instruments executed by or in relation to an exempted partnership or an overseas partnership are exempt from stamp duties (such duties were formerly applicable under the Stamp Duties Act 1976). Thus, stamp duties are not payable upon, for example, an instrument which effects the transfer or assignment of a unit in an exempted partnership or an overseas partnership, or the sale or mortgage of partnership assets; nor are they payable upon the partnership capital.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT NON-PRODUCT RELATED MARKET RISK

See the information contained in this annual report on Form 20-F under Item 5. "Operating and Financial Review and Prospects—Quantitative and Qualitative Disclosures About Market Risks."

ITEM 14. MATERIAL MODIFICATIONS TO THE RIGHTS OF SECURITY HOLDERS AND USE OF PROCEEDS

At the special meeting of our unitholders held on November 16, 2009, our unitholders approved an amendment to our limited partnership agreement reducing the quorum requirement for meetings of the limited partners from 50% to 20%. As such, 20% of the outstanding units of the class or classes for which a meeting has been called (including our units held by the Managing General Partner) represented in person or by proxy shall constitute a quorum at a meeting of limited partners of such class or classes unless any such action by the limited partners requires approval by limited partners holding a greater percentage of the voting power of such units, in which case the quorum shall be such greater percentage.

As of December 31, 2010, an evaluation of the effectiveness of our "disclosure controls and procedures" (as defined in Rules 13a-15(e) and 15d-15(e) of the United States Securities Exchange Act of 1934, or the Exchange Act) was carried out under the supervision and with the participation of persons performing the functions of principal executive and principal financial officers for us and our Manager. Based upon that evaluation, the persons performing the functions of principal executive and principal financial officers for us have concluded that, as of December 31, 2010, our disclosure controls and procedures were effective: (i) to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms; and (ii) to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including the persons performing the functions of principal executive and principal financial officers for us, to allow timely decisions regarding required disclosure.

It should be noted that while our management, including persons performing the functions of principal executive and principal financial officers for us, believe our disclosure controls and procedures provide a reasonable level of assurance that such controls and procedures are effective, they do not expect that our disclosure controls and procedures or internal controls will prevent all error and all fraud. A control system, no matter how well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f). Under the supervision and with the participation of our management, including persons performing the functions of principal executive and principal financial officers for us, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2010, based on the criteria set forth in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway

Commission. Based on evaluation under the Framework in Internal Control—Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2010. Excluded from our evaluation were the controls over financial reporting at Prime, which was acquired on December 8, 2010 and at the Canadian freehold timberlands, the U.S. freehold timberlands, the Australian coal terminal operations and the UK port operations, in which control was acquired on December 31, 2010. The financial statements of these entities in aggregate constitute 93% and 96% of net and total assets, respectively, and 66% of net income of the consolidated and combined financial statement amounts as of and for the year ended December 31, 2010.

Internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The effectiveness of our internal control over financial reporting as of December 31, 2010 has been audited by Deloitte & Touche, LLP, independent registered chartered accountants, who have also audited the financial statements of the partnership, as stated in their reports which are included herein.

There was no change in our internal control over financial reporting during the year ended December 31, 2010, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Our Managing General Partner's board of directors has determined that Danesh Varma possesses specific accounting and financial management expertise, that he is the audit committee financial expert as defined by the U.S. Securities and Exchange Commission, and that he is independent within the meaning of the rules of the NYSE. Our Managing General Partner's Board has also determined that other members of the Audit Committee have sufficient experience and ability in finance and compliance matters to enable them to adequately discharge their responsibilities.

On December 4, 2007, our Managing General Partner adopted a Code of Conduct and Ethics, or the "Code", that applies to the members of the board of directors of the Managing General Partner, our partnership and any officers or employees of the Managing General Partner. We have posted a copy of the Code on our website at www.brookfieldinfrastructure.com/aboutus/governance.

Our Managing General Partner has retained Deloitte & Touche LLP to act as our partnership's and the Holding LP's independent registered chartered accountants.

The table below summarizes the fees for professional services rendered by Deloitte & Touche LLP for the audit of our annual financial statements:

The audit committee of the Managing General Partner pre-approves all audit and non-audit services provided to our partnership and the Holding LP by Deloitte & Touche LLP. In connection with the original registration statement all fees paid to Deloitte & Touche LLP were paid by Brookfield Asset Management Inc., and as such have not been disclosed by our partnership.

ITEM 16E. PURCHASES OF EQUITY SECURITIES BY THE ISSUER AND AFFILIATED PURCHASER

Our partnership may from time-to-time, subject to applicable law, purchase our units for cancellation in the open market, provided that any necessary approval has been obtained. Brookfield has also advised our partnership that it may from time-to-time, subject to applicable law, purchase our units in the market without making an offer to all unitholders.

On December 8, 2010, our partnership announced that the TSX accepted a notice filed by our partnership of its intention to commence a normal course issuer bid. Brookfield Infrastructure believes that at times our units may trade in a price range that does not fully reflect their value. As a result, from time to time, acquiring our units for cancellation represents an attractive use of available funds. Under the normal course issuer bid, the board of directors of our Managing General Partner authorized our partnership to repurchase up to the equivalent of $25 million of our units. Under the rules of the TSX, our partnership may purchase an aggregate of up to 7,818,055 units, representing 6.9% of the public float on December 7, 2010. Under the normal course issuer bid, our partnership may purchase up to 18,312 units on the TSX during any trading day. The price to be paid for our units under the normal course issuer bid will be the market price at the time of purchase. The actual number of units to be purchased and the timing of such purchases will be determined by our partnership, and all purchases will be made through the facilities of the TSX or the NYSE. Repurchases are authorized to commence on December 10, 2010 and will terminate on December 9, 2011, or earlier should our partnership complete its repurchases prior to such date. Repurchases shall occur subject to prevailing market conditions and will be funded from available cash. Repurchases will also be subject to compliance with applicable United States federal securities laws, including Rule 10b-18 under the Exchange Act, as well as applicable Canadian securities laws. All of our units acquired by our partnership under the normal course issuer bid will be cancelled.

In the year ended December 31, 2010, none of our units were repurchased and cancelled under the normal course issuer bid. The following table sets forth the number of units of our partnership purchased and cancelled pursuant to the normal course issuer bid for the periods indicated.

Our corporate practices are not materially different than those required of domestic companies under the NYSE listing standards.

The registrant hereby certifies that it meets all of the requirements for filing an annual report on Form 20-F and that it has duly caused and authorized the undersigned to sign this annual report on its behalf.

We have audited the internal control over financial reporting of Brookfield Infrastructure Partners L.P. (the "Partnership") as of December 31, 2010, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. As described in Management's Annual Report on Internal Control Over Financial Reporting, management excluded from its assessment the internal control over financial reporting at Prime, which was acquired on December 8, 2010 and the Canadian freehold timberlands, the U.S. freehold timberlands, the Australian coal terminal operations and the UK Port operations, which were acquired on December 31, 2010 and whose financial statements constitute 93% and 96% of net and total assets, respectively, and 66% of net income of the consolidated and combined financial statement amounts as of and for the year ended December 31, 2010. Accordingly, our audit did not include the internal control over financial reporting at Prime, the Canadian freehold timberlands, the U.S. freehold timberlands, the Australian coal terminal operations and the UK Port operations. The Partnership's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Partnership's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Partnership maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated and combined financial statements as of and for the year ended December 31, 2010 of the Partnership and our report dated April 26, 2011 expressed an unqualified opinion on those financial statements.

We have audited the accompanying consolidated and combined statements of financial position of Brookfield Infrastructure Partners L.P. (the "Partnership") as of December 31, 2010 and 2009, and January 1, 2009, and the related consolidated and combined statements of operating results, comprehensive income, partnership capital and cash flows for each of the two years in the period ended December 31, 2010. These financial statements are the responsibility of the Partnership's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated and combined financial statements present fairly, in all material respects, the financial position of Brookfield Infrastructure Partners L.P. as of December 31, 2010 and 2009, and January 1, 2009 and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2010, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Partnership's internal control over financial reporting as of December 31, 2010, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated April 26, 2011 expressed an unqualified opinion on the Partnership's internal control over financial reporting.

NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS

For the years ended and as of December 31, 2010 and 2009

Brookfield Infrastructure Partners L.P. (the "partnership") owns and operates utility businesses, transport and energy businesses and timber assets in North and South America, Australasia, and Europe. The partnership was formed as a limited partnership established under the laws of Bermuda, pursuant to a limited partnership agreement dated May 17, 2007, as amended and restated. The partnership's limited partnership units are listed on the New York Stock Exchange and the Toronto Stock Exchange under the symbols "BIP" and "BIP.UN", respectively. The registered office is Canon's Court, 22 Victoria Street, Hamilton, Bermuda.

The following provides information about the partnership's principal subsidiaries as of December 31, 2010 and 2009.

The reporting periods of the subsidiaries are consistent with those of the partnership.

These consolidated and combined financial statements have been prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB"). These are the partnership's first annual consolidated and combined financial statements prepared in accordance with IFRS and IFRS 1 First-time Adoption of International Financial Reporting Standards has been applied. An explanation of how the transition to IFRS has affected the reported financial position, financial performance and cash flows is provided in note 4.

The financial statements were authorized for issue by the Board of Directors on April 15, 2011.

The financial statements have been prepared on the basis of historical cost, except for the revaluation of property, plant and equipment, investment properties, timber, and certain assets and liabilities, which have been measured at fair value. Cost is based on the fair values of the consideration given in exchange for assets. All amounts are presented in US dollars and rounded to the nearest million, unless otherwise noted.

The preparation of financial statements in conformity with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise its judgment in the process of applying Brookfield Infrastructure's accounting policies. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated and combined financial statements are disclosed in note 6.

These consolidated and combined financial statements include the accounts of the partnership and its consolidated (direct and indirect) subsidiaries over which the partnership has control: Holding LP, North American electricity transmission operation, Australian coal terminal operation, European energy distribution operation, Australian railroad operation, UK port operation, Australian energy distribution operation, U.S. freehold timberlands, Canadian freehold timberlands and Prime. Control exists when the partnership has the power, directly or indirectly to govern the financial and operating policies of an entity so as to obtain benefits from its activities. Non-controlling interests in partnership capital and results of the partnership's subsidiaries are shown separately in the consolidated and combined Statements of Financial Position. Together, the partnership and its subsidiaries are referred to as "Brookfield Infrastructure" in these financial statements.

after the voting arrangements were completed. IFRS 3R does not include specific measurement guidance for transfers of businesses or subsidiaries between entities under common control. Accordingly, Brookfield Infrastructure has developed a policy to account for such transactions taking into consideration other guidance set out under the IFRS framework and pronouncements of other standard-setting bodies. The consolidated and combined financial statements of Brookfield Infrastructure are presented to reflect continuing control as follows:

The consolidated and combined financial statements incorporate the assets and liabilities of all subsidiaries of the partnership as at December 31, 2010 and 2009, and the results of all subsidiaries for the years then ended.

The results of subsidiaries acquired or disposed of during the year are included in the Statements of Operating Results and Statements of Comprehensive Income from the effective date of acquisition and up to the effective date of disposal, as appropriate.

Where necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies in line with those used by the partnership.

All intra-group transactions, balances, income and expenses are eliminated in full on consolidation.

pronouncements of other standard-setting bodies. The partnership's policy is to record assets and liabilities recognized as a result of transactions between entities under common control at the carrying value on the transferor's financial statements. The Statements of Operating Results reflect the results of combining entities for all periods presented for which the entities were under the transferor's control, irrespective of when the combination takes place.

Non-controlling interests in subsidiaries are identified separately from Brookfield Infrastructure's partnership capital therein. The non-controlling interests may be initially measured either at fair value or at the non-controlling interests' proportionate share of the fair value of the acquiree's identifiable net assets. The choice of measurement basis is made on an acquisition by acquisition basis. Subsequent to acquisition, the carrying amount of non-controlling interests is the amount of those interests at initial recognition plus the non-controlling interests' share of subsequent changes in partnership capital. Total comprehensive income is attributed to non-controlling interests, even if this results in the non-controlling interests having a deficit balance.

When Brookfield Infrastructure ceases to control a subsidiary, the income or loss on disposal is calculated as the difference between (i) the aggregate of the fair value of the consideration received and the fair value of any retained interest and (ii) the previous carrying amount of the assets (including goodwill), and liabilities of the subsidiary and any non-controlling interests. Amounts previously recognized in other comprehensive income in relation to the subsidiary are accounted for (i.e. reclassified to income or loss or transferred directly to retained earnings) in the same manner as would be required if the relevant assets or liabilities were disposed of. The fair value of any investment retained in the former subsidiary at the date when control is lost is regarded as the fair value on initial recognition for subsequent accounting or, when applicable, the cost on initial recognition of an investment in an associate or jointly controlled entity.

A change in the ownership interest of a subsidiary, without loss of control, is accounted for as an equity transaction.

Acquisitions of subsidiaries and businesses are accounted for using the acquisition method, other than those between and among entities under common control. The consideration of each acquisition is measured at the aggregate of the fair values (at the acquisition date) of assets acquired, liabilities incurred or assumed, and equity instruments issued by Brookfield Infrastructure in exchange for control of the acquiree. Acquisition related costs are recognized in income or loss as incurred and included in administrative expenses.

Where applicable, the consideration for the acquisition includes any asset or liability resulting from a contingent consideration arrangement, measured at its acquisition-date fair value. Subsequent changes in fair values are adjusted against the cost of acquisition where they qualify as measurement period adjustments. All other subsequent changes in the fair value of contingent consideration classified as a liability will be recognized in income or loss, whereas changes in the fair value of contingent consideration classified within partnership capital are not subsequently re-measured.

Where a business combination is achieved in stages, Brookfield Infrastructure's previously held interests in the acquired entity are remeasured to fair value at the acquisition date, that is, the date Brookfield Infrastructure attains control and the resulting gain or loss, if any, is recognized in income or loss. Amounts arising from interests in the acquiree prior to the acquisition date that have previously

been recognized in other comprehensive income are reclassified to income or loss, where such treatment would be appropriate if that interest were disposed of.

If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, Brookfield Infrastructure reports provisional amounts for the items for which the accounting is incomplete. Those provisional amounts are adjusted during the measurement period, or additional assets or liabilities are recognized, to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the amounts recognized as of that date.

The measurement period is the period from the date of acquisition to the date Brookfield Infrastructure obtains complete information about facts and circumstances that existed as of the acquisition date. The measurement period is subject to a maximum of one year subsequent the acquisition date. No adjustments are made to reflect fair values, or recognize any new assets or liabilities, including goodwill, as a result of the combination.

Contingent liabilities acquired in a business combination are initially measured at fair value at the date of acquisition. At the end of subsequent reporting periods, such contingent liabilities are measured at the higher of the amount that would be recognized in accordance with IAS 37 Provisions, Contingent Liabilities and Contingent Assets and the amount initially recognized less cumulative amortization recognized in accordance with IAS 18 Revenue recognition.

An associate is an entity over which Brookfield Infrastructure has significant influence that is neither a subsidiary nor an interest in a joint venture. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies.

Where a Brookfield Infrastructure entity transacts with an associate of Brookfield Infrastructure, income and losses are eliminated to the extent of Brookfield Infrastructure's interest in the relevant associate.

Cash and cash equivalents include cash on hand, demand deposits and highly liquid short-term investments that are readily convertible to known amounts of cash with original maturities of three months or less and which are subject to an insignificant risk of changes in value.

Bank overdrafts are shown within borrowings in current liabilities in the Statements of Financial Position.

Inventories are stated at the lower of cost and net realizable value. If actual demand or market conditions are less favourable than those projected by management, inventory write-downs may be required. Cost is determined on a first-in, first-out basis except for supplies, which are stated using the average cost method.

An item of property, plant and equipment and any significant part initially recognized is derecognized upon disposal or when no future economic benefits are expected from its use or disposal. The gain or loss arising on disposal or retirement of an item of property, plant and equipment is determined as the difference between the sales proceeds and the carrying amount of the asset and is recognized in income or loss.

Property, plant and equipment is depreciated on a straight line basis over the estimated useful lives of each component of the assets as follows:

Depreciation on property, plant and equipment is calculated on a straight-line basis so as to write-off the net cost of each asset over its expected useful life to its estimated residual value. Leasehold improvements are depreciated over the period of the lease or estimated useful life, whichever is the shorter, using the straight-line method. The estimated useful lives, residual values and depreciation method are reviewed at the end of each annual reporting period, with the effect of any changes recognized on a prospective basis.

Subsequent acquisitions of leasehold assets are shown as leasehold improvements.

Land under standing timber is accounted for using the revaluation method and included in property, plant and equipment.

Harvested timber is included in inventory and is measured at the lower of fair value less estimated costs to sell at the time of harvest and net realizable value.

Brookfield Infrastructure uses the fair value method to account for real estate classified as investment property. A property is determined to be an investment property when it is principally held to earn rental income or for capital appreciation, or both. Investment property is initially measured at cost including transaction costs. Subsequent to initial recognition, investment properties are carried at fair value. Gains or losses arising from changes in fair value are included in income.

Land of Brookfield Infrastructure's U.S. and Canadian freehold timberlands which has been determined to have a higher and better use and which is no longer used for the harvest and growth of timber is classified as investment property.

Fair values are primarily determined by discounting the expected future cash flows of each property, generally over a term of 10 years, using a discount and terminal capitalization rate reflective of the characteristics, location and market of each property. The future cash flows of each property are based upon, among other things, rental income from current leases and assumptions about rental income from future leases reflecting current conditions, less future cash outflows in respect of such current and future leases. Brookfield Infrastructure determines fair value using both internal and external valuations.

Borrowings are recorded initially at fair value, net of transaction costs. Subsequent to initial recognition, borrowings are measured at amortized cost with any difference between the initial recognized amount and the redemption value being recognized in income and loss over the period of the borrowing using the effective interest rate method. Fees paid on the establishment of loan facilities, which are not an incremental cost relating to the actual draw-down of the facility, are recognized as prepayments and amortized on a straight-line basis over the term of the facility.

Borrowings are classified as current liabilities unless Brookfield Infrastructure has an unconditional right to defer settlement of the liability for at least 12 months after the reporting date.

Subsequent to initial recognition, intangible assets acquired in a business combination are reported at cost less accumulated amortization and accumulated impairment losses, on the same basis as intangible assets acquired separately.

Public service concessions that provide Brookfield Infrastructure the right to charge users for a service in which the service and fee is regulated by the grantor are accounted for as an intangible asset.

Concession arrangements were acquired as part of the acquisition of the Australian coal terminal operation and were recognized at their fair value. These intangible assets relate to the right to control and use a specific port for a contractual length of time. These concession arrangements are amortized over the life of the contractual arrangement (91 years).

The conservancy right was acquired as part of the acquisition of the UK Port operation and was recorded at its fair value. As a right in perpetuity issued by the Statutory Harbour Authority in the UK, the conservancy right is classified as having an indefinite life.

Intangible assets acquired separately are carried at cost less accumulated amortization and accumulated impairment losses. Amortization is recognized on a straight-line basis over the intangible assets' estimated useful lives. The amortization expense on intangible assets with finite lives is recognized in the Statements of Operating Results in the expense category consistent with the function of the intangible asset. The estimated useful life and amortization method are reviewed at the end of each annual reporting period, with the effect of any changes in estimate being accounted for on a prospective basis.

Gains or losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset and are recognized in the Statements of Operating Results when the asset is derecognized.

At each reporting date Brookfield Infrastructure assesses whether there is any indication that assets are impaired, other than those measured at fair value with changes in fair value recorded in net income. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). Where an asset does not generate cash inflows that are largely independent from cash inflows from other assets, Brookfield Infrastructure estimates the recoverable amount of the cash-generating unit to which the asset belongs. Where a reasonable and consistent basis of allocation can be identified, corporate assets are also allocated to individual cash-generating units; otherwise, they are allocated to the smallest group of cash-generating units for which a reasonable and consistent allocation basis can be identified.

Intangible assets with indefinite useful lives and intangible assets not yet available for use are tested for impairment annually, and whenever there is an indication that the asset may be impaired.

An impairment is recognized if the recoverable amount of the asset or cash-generating unit is estimated to be less than the carrying amount. The impairment loss is recognized immediately in income or loss, unless the relevant asset is carried at a revalued amount, in which case the impairment loss is treated as a revaluation reserve decrease. The recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted. The projection of future cash flows takes into account the relevant operating plans and management's best estimate of the most probable set of conditions anticipated to prevail. These budgets and forecasts are generally covering a period of five years. For longer periods, a long-term growth rate is calculated and applied to project future cash flows after the fifth year.

At the end of each reporting period, the partnership assesses whether there is any indication that an impairment loss recognized in prior periods for any asset (or cash-generating unit) other than goodwill may no longer exist or may have decreased. If any such indication exists, the partnership

estimates the recoverable amount of the asset (or cash-generating unit) and determines whether reversal of the prior period impairment is appropriate. Where an impairment loss subsequently reverses, the carrying amount of the asset (or cash-generating unit) is increased to the revised estimate of its recoverable amount, but only to the extent that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized in previous years.

A reversal of an impairment loss is recognized immediately in income or loss, unless the relevant asset is carried at fair value, in which case the reversal of the impairment loss is treated as a revaluation reserve increase.

Goodwill arising from a business combination is recognized as an asset at the date that control is acquired (the acquisition date). Goodwill is measured as the excess of the sum of the consideration transferred, the fair value of any non-controlling interests in the acquiree, and the fair value of the acquirer's previously held equity interest in the acquiree (if any) over the net of the acquisition-date amounts of the identifiable assets acquired and liabilities assumed.

If, after reassessment, Brookfield Infrastructure's interest in the fair value of the acquiree's identifiable net assets exceeds the sum of the consideration transferred, the amount of any non-controlling interests in the acquiree and the fair value of the acquirer's previously held equity interest in the acquiree (if any), the excess is recognized immediately in income or loss as a bargain purchase gain.

Goodwill is not amortized but is reviewed for impairment at least annually. For the purpose of impairment testing, goodwill is allocated to each of Brookfield Infrastructure's cash-generating units expected to benefit from the synergies of the business combination. Cash-generating units to which goodwill has been allocated are tested for impairment annually or more frequently when there is an indication that the unit may be impaired.

If the recoverable amount of the cash-generating unit is less than the carrying amount, the impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the unit and then to the other assets of the unit pro-rata on the basis of the carrying amount of each asset in the unit. An impairment loss recognized for goodwill is recognized immediately in income or loss and is not reversed in a subsequent period.

On disposal of a subsidiary, the attributable amount of goodwill is included in the determination of the income or loss on disposal of the operation.

Where a bargain purchase arises, identification and measurement of assets and liabilities and the measurement of cost will be reassessed before recognizing a gain on bargain purchase immediately in the Statements of Operating Results.

Financial assets are classified into the following specified categories: financial assets 'at fair value through profit or loss', 'held-to-maturity' investments, 'available-for-sale' financial assets, and 'loans and receivables'. The classification depends on the nature and purpose of the financial assets and is determined at the time of initial recognition.

All financial assets are recognized and derecognized on the trade date where the purchase or sale of a financial asset is under a contract whose terms require delivery of the financial asset within the timeframe established by the market concerned, and are initially measured at fair value, plus transaction costs, except for those financial assets classified as fair value through profit or loss, which are initially measured at fair value.

Investments are recognized and derecognized on the trade date where the purchase or sale of an investment is under a contract whose terms require delivery of the investment within the timeframe established by the market concerned, and are initially measured at fair value, net of transaction costs except for those financial assets classified as at fair value through profit or loss which are initially measured at fair value.

The effective interest method is a method of calculating the amortized cost of a debt instrument and of allocating interest income or expense over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash receipts through the expected life of the debt instrument, or where appropriate, a shorter period, to the net carrying amount on initial recognition.

Income is recognized on an effective interest rate basis for debt instruments other than those financial assets classified as 'at fair value through profit or loss'.

Accounts receivable, loans and other receivables that have fixed or determinable payments that are not quoted in an active market are classified as 'loans and receivables'. Loans and receivables are measured at amortized cost using the effective interest method, less any impairment.

Financial assets are assessed for indicators of impairment at each reporting date. Financial assets are considered to be impaired where there is objective evidence that as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows of the investment have been affected.

The carrying amount of financial assets are reduced by the impairment loss directly for all financial assets with the exception of accounts receivable, where the carrying amount is reduced through the use of an allowance account. When accounts receivable are considered uncollectible, they are written off against the allowance account. Subsequent recoveries of amounts previously written off are credited against the allowance account. Changes in the carrying amount of the allowance account are recognized in income or loss.

Brookfield Infrastructure derecognizes a financial asset only when the contractual rights to the cash flows from the asset expire, or when it transfers the financial asset and substantially all the risks and rewards of ownership of the asset to another entity. If Brookfield Infrastructure neither transfers nor retains substantially all the risks and rewards of ownership and continues to control the transferred

asset, Brookfield Infrastructure recognizes its retained interest in the asset and an associated liability for amounts it may have to pay.

Brookfield Infrastructure and its subsidiaries selectively enter into a variety of derivative financial instruments, including foreign exchange forward contracts and interest rate swaps, to manage its exposure to financial risks, including interest rate, foreign exchange and commodity risks. Further details of derivative financial instruments are disclosed in notes 11, 19, and 36.

Derivatives are initially recognized at fair value determined on a credit adjusted basis, on the date a derivative contract is entered into and are subsequently remeasured to their fair value at the end of each reporting period. The resulting gain or loss is recognized in income and loss immediately unless the derivative is designated and effective as a hedging instrument, in which event the timing of the recognition in income or loss depends on the nature of the hedge relationship.

A derivative with a positive fair value is recognized as a financial asset; a derivative with a negative fair value is recognized as a financial liability. A derivative is presented as a non-current asset or non-current liability if the remaining maturity of the instrument is more than 12 months and it is not expected to be realized or settled within 12 months. Other derivatives are presented as current assets or current liabilities.

Brookfield Infrastructure designates certain hedging instruments, which include derivatives, embedded derivatives and non-derivatives in respect of foreign currency risk, as either fair value hedges, cash flow hedges, or hedges of net investments in foreign operations. Hedges of foreign exchange risk on firm commitments are accounted for as cash flow hedges.

Hedge accounting is applied when the derivative is designated as a hedge of a specific exposure and there is assurance that it will continue to be effective as a hedge based on an expectation of offsetting cash flows from forecasted transactions or fair value changes from assets and liabilities. Hedge accounting is discontinued prospectively when the derivative no longer qualifies as a hedge or the hedging relationship is terminated. Once discontinued, the cumulative change in fair value of a derivative that was previously recorded in comprehensive income by the application of hedge accounting is recognized in income over the remaining term of the original hedging relationship.

Note 36 sets out details of the fair values or the derivative instruments used for hedging purposes.

Hedge accounting is discontinued when Brookfield Infrastructure revokes the hedging relationship, when the hedging instrument expires or is sold, terminated, or exercised, or no longer qualifies for hedge accounting. The fair value adjustment to the carrying amount of the hedged item arising from the hedged risk is amortized to income or loss from that date.

The effective portions of changes in the fair value of derivatives that are designated and qualify as cash flow hedges are deferred in other comprehensive income. The gain or loss relating to the ineffective portion is recognized immediately in income or loss.

Hedge accounting is discontinued when Brookfield Infrastructure revokes the hedging relationship, when the hedging instrument expires or is sold, terminated, or exercised, or no longer qualifies for hedge accounting. Any gain or loss accumulated in partnership capital at that time remains in partnership capital and is recognized when the forecast transaction is ultimately recognized in income or loss. When a forecast transaction is no longer expected to occur, the gain or loss accumulated in partnership capital is recognized immediately in income or loss.

Derivative financial instruments that are not designated as hedges are carried at estimated fair value, and gains or losses arising from changes in fair value are recognized in income in the period the changes occur. Realized and unrealized gains on other derivatives not designated as hedges are recorded as income in the period in which they are realized.

The fair value of financial instruments that are traded in active markets at each reporting date is determined by reference to quoted market prices or dealer price quotations, without any deduction for transaction costs. For financial instruments not traded in an active market, the fair value is determined using appropriate valuation techniques. Such techniques may include using recent arms length market transactions; reference to the current fair value of another instrument that is substantially the same; a discounted cash flow analysis; or other valuation models.

Income tax expense represents the sum of the tax currently payable and deferred tax.

Current income tax assets and liabilities are measured at the amount expected to be paid to tax authorities, net of recoveries based on the tax rates and laws enacted and substantively enacted at the reporting date. Current income tax relating to items recognized directly in partnership capital are also recognized directly in partnership capital.

Deferred income tax liabilities are provided for using the liability method on temporary differences between the tax bases used in the computation of taxable income and carrying amounts of assets and liabilities in the financial statements. Deferred income tax assets are recognized for all deductible temporary differences, carry forward of unused tax credits and unused tax losses, to the extent that it is probable that deductions, tax credits and tax losses can be utilized. Such deferred tax assets and liabilities are not recognized if the temporary difference arises from goodwill or from the initial recognition (other than in a business combination) of other assets and liabilities in a transaction that affects neither the taxable income nor the accounting income. The carrying amount of deferred income tax assets are reviewed at each reporting date and reduced to the extent it is no longer probable that the income tax asset will be recovered.

Deferred tax liabilities are recognized for taxable temporary differences associated with investments in subsidiaries and associates, and interests in joint ventures, except where Brookfield Infrastructure is able to control the reversal of the temporary difference and it is probable that the temporary differences will not reverse in the foreseeable future. Deferred tax assets arising from deductible temporary differences associated with such investments and interests are only recognized to the extent that it is probable that there will be sufficient taxable income against which to utilize the benefits of the temporary differences and they are expected to reverse in the foreseeable future.

The carrying amount of deferred tax assets is reviewed at the end of the each reporting period and reduced to the extent that it is no longer probable that sufficient taxable income will be available to allow all or part of the tax asset to be recovered.

Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply in the period in which the liability is settled or the asset realized, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which Brookfield Infrastructure expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority and Brookfield Infrastructure intends to settle its current tax assets and liabilities on a net basis.

The U.S. dollar is the functional and presentation currency of the partnership. Each of the partnership's subsidiaries determines its own functional currency and items included in the financial statements of each subsidiary are measured using that functional currency.

Assets and liabilities of foreign operations having a functional currency other than the U.S. dollar are translated at the rate of exchange prevailing at the reporting date and revenues and expenses at average rates during the period. Gains or losses on translation are included as a component of partnership capital and non-controlling interest. Gains or losses on foreign currency denominated balances and transactions that are designated as hedges of net investments in these operations are reported in the same manner.

Foreign currency denominated monetary assets and liabilities are translated using the closing rate. Non-monetary assets and liabilities measured at fair value are translated at the rate of exchange prevailing at the date when the fair value was determined. Revenues and expenses are measured at average rates during the period. Gains or losses on translation of these items are included in income. Gains or losses on transactions which hedge these items are also included in income. Foreign currency denominated non-monetary assets and liabilities, measured at historic cost, are translated at the rate of exchange at the transaction date.

On the disposal of a foreign operation (i.e. a disposal of Brookfield Infrastructure's entire interest in a foreign operation, or a disposal involving loss of control over a subsidiary or loss of significant influence over an associate), all of the accumulated exchange differences in respect of that operation attributable to Brookfield Infrastructure are reclassified to income or loss. Any exchange differences that have previously been attributed to non-controlling interests are derecognized, but they are not reclassified to income or loss.

Goodwill and fair value adjustments arising on the acquisition of a foreign operation are treated as assets and liabilities of the foreign operation and translated at the closing rate.

Non-current assets and disposal groups are classified as held for sale if their carrying amount will be recovered principally through a sale transaction rather than through continuing use. This condition is regarded as met only when the sale is highly probable and the non-current asset (or disposal group) is available for immediate sale in its present condition. Management must be committed to the sale, which should be expected to qualify for recognition as a completed sale within one year from the date of classification.

When Brookfield Infrastructure is committed to a sale plan involving loss of control of a subsidiary, all of the assets and liabilities of that subsidiary are classified as held for sale when the criteria described above are met, regardless of whether Brookfield Infrastructure will retain a non-controlling interest in its former subsidiary after the sale.

Non-current assets (and disposal groups) classified as held for sale are measured at the lower of their previous carrying amount and fair value less costs to sell.

Non-current assets classified as held for sale and the assets of a disposal group are presented separately from other assets in the Statements of Financial Position. The liabilities of a disposal group classified as held for sale are presented separately from other liabilities in the Statements of Financial Position.

The profit or loss arising on reclassification or sale of a disposal group is recognized in discontinued operations.

Property, plant and equipment and intangible assets once classified as held for sale are not depreciated or amortized.

Accounts payable and other liabilities are recognized when Brookfield Infrastructure becomes obliged to make future payments resulting from the purchase of goods and services.

Provisions are recognized when Brookfield Infrastructure has a present obligation (legal or constructive) as a result of a past event, it is probable that Brookfield Infrastructure will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation.

The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the end of the reporting period, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the obligation, its carrying amount is the present value of those cash flows.

When some or all of the economic benefits required to settle a provision are expected to be recovered from a third party, the receivable is recognized as an asset if it is virtually certain that reimbursement will be received and the amount of the receivable can be measured reliably.

Preference shares, which are mandatorily redeemable on a specific date, are classified as liabilities. The dividends on these preference shares are recognized in the Statements of Operating Results as finance costs.

The Holding LP has issued redeemable partnership units that may, at the request of the holder, require the Holding LP to redeem all or a portion of the holder's units for cash. This right is subject to decisions made by the partnership which entitles it to elect to acquire any units presented to Holding LP in exchange for similar number of the partnership's units (subject to certain customary adjustments). As the partnership, at its sole discretion, has the right to settle the obligation with its partnership units, the redeemable partnership units are therefore classified as limited partners' capital.

Revenue is recognized to the extent that it is probable that the economic benefits will flow to Brookfield Infrastructure and the revenue can be reliably measured, regardless of when the payment is being made.

Revenue is measured at the fair value of the consideration received or receivable. Amounts disclosed as revenue are net of customer returns, trade allowances, rebates and other similar allowances.

Brookfield Infrastructure recognizes revenue when the specific criteria have also been met for each of Brookfield Infrastructure's activities as described below. Cash received by Brookfield Infrastructure from customers is recorded as deferred revenue until revenue recognition criteria are met.

Revenues from the sale of logs and related products and services to external customers is recognized when significant risk and rewards of ownership are transferred, which is generally when the product is shipped and title passes, and collectability is reasonably assured.

Revenue from utilities infrastructure is derived from the distribution and transmission of energy as well as from Brookfield Infrastructure's Australian coal terminal. Distribution and transmission revenue is recognized when services are rendered based upon usage or volume during that period. Terminal infrastructure charges are charged at set rates per tonne of coal based on each customer's annual contracted tonnage and is then recognized on a pro-rata basis each month. Brookfield Infrastructure's Australian coal terminal also recognizes variable handling charges based on tonnes of coal shipped through the terminal.

Revenue from transport and energy infrastructure consists primarily of energy distribution income and freight services revenue. Energy distribution income is recognized when services are provided and are rendered based upon usage or volume throughput during the period. Freight services revenue is recognized at the time of the provision of services.

Brookfield Infrastructure has adopted IFRS effective January 1, 2010. Prior to the adoption of IFRS Brookfield Infrastructure prepared its financial statements in accordance with U.S. Generally Accepted Accounting Principles (GAAP). As stated in note 3, these are Brookfield Infrastructure's first annual consolidated and combined financial statements prepared in accordance with IFRS. Brookfield Infrastructure's transition date was January 1, 2009 (the "transition date") and Brookfield Infrastructure has prepared its opening IFRS Statements of Financial Position as at that date.

In preparing its opening IFRS Statements of Financial Position, Brookfield Infrastructure has adjusted amounts reported previously in financial statements prepared in accordance with U.S. GAAP. An explanation of how the transition from U.S. GAAP to IFRS has affected Brookfield Infrastructure's financial position, financial performance and cash flows is set out in the following tables and the notes that accompany the tables. In reconciling the amounts previously reported under U.S. GAAP to those

included in these financial statements prepared under IFRS, adjustments recorded to convert the previously reported U.S. GAAP amounts to the reported IFRS amounts are separately presented from those recorded adjustments necessary to give effect to the acquisition of Brookfield Infrastructure's subsidiaries through the common control transactions described in note 3. The IFRS transition date for our U.S. and Canadian freehold timberlands and our North American electricity transmission operation acquired through such common control transactions is consistent with the transition date of Brookfield Infrastructure.

Brookfield Infrastructure from time to time enters into derivative contracts to hedge against foreign currency risks on certain cash flows that do not qualify for hedge accounting.

Hindsight was not used to create or revise estimates and accordingly the estimates previously made by Brookfield Infrastructure under U.S. GAAP are consistent with their application under IFRS.

The following is a reconciliation of Brookfield Infrastructure's net income reported in accordance with U.S. GAAP to its net income in accordance with IFRS for the year ended December 31, 2009.

US$ MILLIONS			For the Year Ended December 31, 2009

The partnership entered into a voting agreement and effectively gained control of the Holding LP. As a result, the partnership consolidates the Holding LP and the redeemable partnership units issued by the Holding LP are classified as limited partners' capital in Brookfield Infrastructure (see note 3 for details).

For IFRS Brookfield Infrastructure's standing timber are measured at fair value less estimated point-of-sale costs, with changes in fair value or point of sale costs recorded in income during the period of change. Under U.S. GAAP Brookfield Infrastructure had recorded such assets at historic cost and charged a depletion amount to income based upon harvest levels.

Lands under standing timber, and transmission infrastructure were recorded at fair value on transition, at values in excess of their recorded amount under U.S. GAAP. Accordingly, these increased carrying values resulted in higher depreciation during the period.

(d) Reconciliation of Comprehensive (Loss) Income as Reported Under U.S. GAAP and IFRS

The following is a reconciliation of Brookfield Infrastructure's comprehensive income reported in accordance with U.S. GAAP to its comprehensive income in accordance with IFRS for the year ended December 31, 2009.

Brookfield Infrastructure measures land under standing timber, power generation and transmission infrastructure assets at their revalued amount. Revaluations of these assets in excess of their cost base less accumulated depreciation are recorded as a component of partnership capital in revaluation surplus. During 2009 Brookfield Infrastructure incurred a $45 million decrease in the revalued amount of its assets.

(e) Reconciliation of partnership capital as reported under U.S. GAAP and IFRS

The following is a reconciliation of Brookfield Infrastructure's partnership capital in accordance with U.S. GAAP to its partnership capital in accordance with IFRS at the transition date and December 31, 2009:

IN US$ MILLIONS		As of December 31, 2009			As of January 1, 2009

Partnership capital attributable to partnership as reported under U.S. GAAP		$	1,074		$	547
Adjustment for common control transaction (i)			726			352

Partnership capital attributable to partnership as reported under IFRS		$	1,877		$	1,043

Brookfield Infrastructure's standing timber is measured at fair value less estimated point-of-sale costs for IFRS, whereas for U.S. GAAP Brookfield Infrastructure recorded such assets at historic cost less accumulated depletion, or as inventory. The increase in partnership capital relates to the difference in the fair value, less estimated point-of-sale costs, of Brookfield Infrastructure's standing timber and other standing timber and their carrying amounts for U.S. GAAP.

Brookfield Infrastructure elected to measure certain items of property, plant and equipment at fair value or revaluation amounts determined previously under U.S. GAAP and use that amount as deemed cost on transition to IFRS. The established deemed cost amount will be amortized to income over the useful lives of the assets.

Under IFRS Brookfield Infrastructure measures land under standing timber and property, plant and equipment at their revalued amount, being the fair value at the date of the revaluation less any subsequent accumulated depreciation and any accumulated impairment losses, whereas for U.S. GAAP Brookfield Infrastructure recorded such assets at historic cost less accumulated depreciation.

Brookfield Infrastructure measures its land used for commercial property purposes and investment property at fair value under IFRS, whereas for U.S. GAAP Brookfield Infrastructure had recorded such assets at historic cost less any accumulated amortization. The increase in partnership capital relates to the difference in the fair value of investment property and their carrying amounts for U.S. GAAP.

There was no change in measurement for the investment property held at the UK Port operation as Brookfield Infrastructure acquired control of the UK Port operation as of December 31, 2010.

Deferred taxes are impacted by the change in temporary differences resulting from the effect of the IFRS reconciling items described above. The deferred taxes relate to the following adjustments: revaluation of land under standing timber, power generation and transmission infrastructure, measurement of inventories and standing timber.

There were no material effects on the consolidated Statements of Cash Flows as prepared in accordance with U.S GAAP from the adoption of IFRS.

IFRS 9 Financial Instruments ("IFRS 9") was issued by the IASB on November 12, 2009, and will replace IAS 39 Financial Instruments: Recognition and Measurement ("IAS 39"). IFRS 9 uses a single approach to determine whether a financial asset is measured at amortized cost or fair value, replacing the multiple classification options in IAS 39. The approach in IFRS 9 is based on how an entity manages its financial instruments in the context of its business model and the contractual cash flow characteristics of the financial assets. The new standard also requires a single impairment method to be used, replacing the multiple impairment methods in IAS 39. IFRS 9 is effective for annual periods beginning on or after January 1, 2013. Brookfield Infrastructure is currently evaluating the impact of IFRS 9 on its financial statements.

On November 4, 2009, the IASB issued a revised version of IAS 24 Related Party Disclosures ("IAS 24"). IAS 24 requires entities to disclose in their financial statements information about transactions with related parties. Generally, two parties are related to each other if one party controls, or significantly influences, the other party. IAS 24 has simplified the definition of a related party and removed certain of the disclosures required by the predecessor standard. The revised standard is effective for annual periods beginning on or after January 1, 2011. Brookfield Infrastructure is currently evaluating the impact of the change to IAS 24 on its financial statements.

In December 2010, the IASB made amendments to IAS 12, Income Taxes ("IAS 12") that are applicable to the measurement of deferred tax liabilities and deferred tax assets where investment property is measured using the fair value model in IAS 40, Investment Property. The amendments introduce a rebuttable presumption that an investment property is recovered entirely through sale. This presumption is rebutted if the investment property is held within a business model whose objective is to consume substantially all of the economic benefits embodied in the investment property over time, rather than through sale. The amendments to IAS 12 are effective for annual periods beginning on or after January 1, 2012. Brookfield Infrastructure is currently evaluating the impact of the change to IAS 12 on its financial statements.

NOTE 6. CRITICAL ACCOUNTING JUDGEMENTS AND KEY SOURCES OF ESTIMATION UNCERTAINTY

The application of Brookfield Infrastructure's accounting policies which are described in note 3 and the preparation of financial statements requires management to select appropriate accounting policies and to make judgements, estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses, that are not readily apparent from other sources, during the reporting period. These estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods.

Critical judgments made by management and utilized in the normal course of preparing Brookfield Infrastructure's financial statements are outlined below.

IFRS framework and pronouncements of other standard-setting bodies. The partnership's policy is to record assets and liabilities recognized as a result of transactions between entities under common control at the carrying value on the transferor's financial statements, and to have the Statements of Operating Results reflect the results of combining entities for all periods presented for which the entities were under the transferor's common control, irrespective of when the combination takes place.

Brookfield Infrastructure's accounting polices relating to assets held for sale are described in note 3(q). In applying this policy, judgment is applied in determining whether certain assets should be reclassified to assets held for sale on the consolidated and combined Statements of Financial Position. Judgment is also applied in determining whether the results of operations associated with the assets should be recorded in discontinued operations on the consolidated and combined Statements of Operating Results. Brookfield Infrastructure will reclassify the results of operations associated with certain assets to discontinued operations where the asset represents part of a disposal group or segment.

Brookfield Infrastructure's accounting policies relating to derivative financial instruments are described in note 3(n). The critical judgments inherent in these policies relate to applying the criteria to the assessment of the effectiveness of hedging relationships.

Significant estimates and assumptions made by management and utilized in the normal course of preparing Brookfield Infrastructure's financial statements are outlined below.

Property, plant and equipment is revalued on a regular basis. When determining the value of property, plant and equipment using the revaluation method, Brookfield Infrastructure uses the following critical assumptions and estimates: the timing of forecasted revenues; future sales prices and margins; future sales volumes; future regulatory rates; maintenance and other capital expenditures; discount rates; terminal capitalization rates; terminal valuation dates; useful lives and residual values.

The fair value of standing timber is determined with the assistance of an independent valuation expert using recognized valuation techniques. Key estimates and assumptions in determining the fair value of standing timber are: the timing of forecasted revenues and timber prices; estimated selling costs; sustainable felling plans; growth assumptions; silviculture costs; discount rates; terminal capitalization rates and terminal valuation dates.

The fair value of investment property is determined with the assistance of an independent valuation expert using recognized valuation techniques. These techniques comprise both the Yield Method and the Discounted Cash Flow Method. In some cases, the fair values are determined based

on recent real estate transactions with similar characteristics and location to those of Brookfield Infrastructure assets.

The determination of the fair value of investment property requires the use of estimates such as future cash flows from assets (such as lettings, tenants' profiles, future revenue streams, capital values of fixtures and fittings, plant and machinery, any environmental matters and the overall repair and condition of the property) and discount rates applicable to those assets. These estimates are based on local market conditions existing at reporting date.

Volatility in the global financial system is reflected in commercial real estate markets. There was a significant reduction in transaction volumes in 2009 and, to a lesser extent, into 2010. Therefore, in arriving at their estimates of market values as at December 31, 2009, and December 31, 2010, the independent valuation experts used their market knowledge and professional judgment and did not rely solely on historical transactional comparables. In these circumstances, there was a greater degree of uncertainty than which exists in a more active market in estimating the market values of investment property.

Goodwill is assessed for impairment on an annual basis, or more often if indicators of potential impairment exist. Determining whether goodwill and intangibles with indefinite lives are impaired requires an estimation of the value-in-use or fair value less costs to sell of the cash-generating units to which goodwill has been allocated. The value-in-use calculation requires the entity to estimate the future cash flows expected to arise from the cash-generating unit and a suitable discount rate in order to calculate present value. The cash flows are derived from the budget for the next five years and do not include restructuring activities that Brookfield Infrastructure is not yet committed to or significant future investments that will enhance the performance of the cash generating unit being tested. The recoverable amount is most sensitive to the discount rate used as well as the expected cash flows and the growth rate used for extrapolation purposes.

The carrying amount of goodwill and intangibles with indefinite lives at the reporting date was $591 million and $332 million respectively (2009: $591 million and $306 million, Opening 2009: $591 million and $nil).

Brookfield Infrastructure accounts for business combinations using the acquisition method of accounting. This method requires the application of fair values for both the consideration given and the assets and liabilities acquired. The calculation of fair values is often predicated on estimates and judgments including future cash flows, revenue streams and value-in-use calculations (refer note 7 for details of business combinations). The determination of the fair values may remain provisional for up to 12 months from the date of acquisition due to the time required to obtain independent valuations of individual assets and to complete assessments of provisions. When the accounting for a business combination has not been completed as at the reporting date, this is disclosed in the financial statements, including observations on the estimates and judgments made as of the reporting date.

As described in note 3, Brookfield Infrastructure reviews the estimated useful lives of property, plant and equipment at the end of each annual reporting period. The estimation of the useful lives of property, plant and equipment has been based on historical experience as well as manufacturers' warranties (for plant and equipment) and lease terms (for leased equipment). In addition, the condition of assets is assessed throughout the year and considered against the remaining useful life. Adjustments to useful lives are made when necessary.

The table below summarizes the total amount of fair value gain and other items arising from business combinations in the years ended December 31, 2010 and 2009:

Below is a discussion of the various business combinations that gave rise to the fair value gain and other items.

On November 20, 2009, Brookfield Infrastructure acquired 40% of Prime for cash consideration of $666 million. At that time, the investment was classified as an investment in an associate and accounted for using the equity method. Prime held various interests in assets, including an Australian coal terminal operation, Australian railroad operation, Australian energy distribution operation and European energy distribution operation.

On December 8, 2010, Brookfield Infrastructure acquired the remaining 60% in Prime in a transaction whereby Prime security holders received 0.24 partnership units per Prime security held and A$0.20 per Prime security in a special distribution. Pursuant to the acquisition, Brookfield Infrastructure acquired control of Prime, issuing 49.8 million units with a value at issuance of $1.1 billion. Brookfield Infrastructure acquired control of Prime and accounted for the transaction in accordance with IFRS 3R.

As a part of the acquisition, Prime security holders were given the option to sell their units at a price of A$4.55 per unit. Brookfield Infrastructure funded this purchase with the sale of Brookfield Infrastructure units to Brookfield, its ultimate parent company. Through this option, Brookfield Infrastructure issued 0.9 million units for $17 million. All of the proceeds were used to purchase Prime units.

Effective December 31, 2010, the partnership also entered into an arrangement with an affiliate of Brookfield whereby the partnership gained effective control of its Australian coal terminal operation. The arrangement has been accounted for in accordance with Brookfield Infrastructure's accounting

policy with respect to transfers between entities under common control. See note 3(a) for further details.

Under the requirements of IFRS 3R, Brookfield Infrastructure accounted for these transactions as a deemed disposition of its 40% interest in Prime and its interest in the Australian coal terminal operation for consideration equal to the fair market value of the equity interest combined with a concurrent acquisition of 100% of Prime and the Australian coal terminal operation. The deemed disposition was accounted for as follows (in US$ millions):

The following summarizes the major classes of consideration transferred, and the assets acquired and liabilities assumed at the acquisition date as a result of the concurrent acquisition of Prime and the Australian coal terminal operation.

US$ MILLIONS

2010:
Cash and cash equivalents	$	125
Accounts receivable and other		2,071
Property, plant and equipment		1,931
Intangible assets		2,490
Investments in associates		777
Deferred income tax asset		363
Accounts payable and other		(2,323	)
Non-recourse borrowings		(2,606	)
Deferred income tax liability		(335	)
Non-controlling interest		(251	)

Net assets acquired	$	2,242

The non-controlling interests in Prime recognized at the acquisition date relates to the remaining interest in the Australian coal terminal operation owned by third parties and was measured at fair value of the non-controlling interests, amounting to $251 million.

An excess of fair value over consideration paid of $166 million was recognized as follows (in U.S.$ millions):

As required by IFRS 3R, Brookfield Infrastructure reassessed the identification and measurement of assets and liabilities and the measurement of costs. This reassessment resulted in no changes and thus the bargain purchase gain of $166 million and remeasurement gain of $239 million were recognized immediately as fair value gains and other items on the Statements of Operating Results. Brookfield Infrastructure considers that the gain is reflective of industry conditions at the time of the negotiation of the acquisition.

See note 6, "Critical Accounting Judgements and Key Sources of Estimation Uncertainty", for further discussion of significant assumptions used in measuring these fair values.

As this transaction resulted in a bargain purchase gain there is no recognized goodwill which would be expected to be deductible for income tax purposes.

On November 20, 2009, Brookfield Infrastructure acquired a 60% interest in its UK port operation for consideration of $103 million, which was paid in November 2009. In 2010, the partnership entered into several arrangements with various affiliates of Brookfield whereby the partnership gained control of the UK port operation. These transactions are accounted for as a transfer between entities under common control. See note 3(a) for further details. The information below relates to the 2009 acquisition as this is the transaction that resulted in the partnership obtaining control.

The following summarizes the major classes of consideration transferred and the assets acquired and liabilities assumed at the acquisition date.

Fair value of assets and liabilities acquired as at November 20, 2009 (provisional):

US$ MILLIONS

2009:
Cash and cash equivalents	$	15

Non-recourse borrowings		(408	)
Deferred income tax liability		(100	)
Non-controlling interest		(65	)

Net assets acquired	$	103

The non-controlling interests in Brookfield Infrastructure's UK port operation recognized at the acquisition date were measured at fair value and amounted to $65 million. This fair value was estimated by applying the same key inputs and values used in Brookfield Infrastructure's valuation of its UK port operation.

As a result of the common control transaction which resulted in Brookfield Infrastructure acquiring control directly in its UK port operation, see note 3(a), Brookfield Infrastructure remeasured its previously held equity interest to fair value. This resulted in a remeasurement gain of $28 million which was recognized immediately as fair value gains and other items in the Statements of Operating Results.

An excess of fair value over consideration paid for Brookfield Infrastructure's original equity interest of $28 million was recognized as follows (in U.S.$ millions):

Consistent with its strategy of participating in Brookfield sponsored partnerships, Brookfield Infrastructure acquired a portion of its interest in the UK port operation through a Brookfield sponsored infrastructure fund.

From December 2009 until its final close in September 2010, the Brookfield sponsored infrastructure fund periodically admitted new limited partners which resulted in a reduction in Brookfield Infrastructure's ownership interests in the UK port operation. In conjunction with these transactions, we received approximately $20 million, representing the original cost of the investment plus a notional interest charge.

In addition, Brookfield Infrastructure acquired Brookfield's interest in the UK port operation for approximately $27 million representing the original cost of the investment plus a notional interest charge.

As a result of these transactions, Brookfield Infrastructure's interest in its UK port operation decreased to 59%.

Brookfield Infrastructure incurred equity issuance related costs of $12 million on the Prime acquisition. The costs have been included in the partnership's capital.

Brookfield Infrastructure's results from operations for the year ended December 31, 2010, include $59 million of revenue and $24 million of net income from Prime.

Had the Prime business combination been effective January 1, 2010, the revenue of Brookfield Infrastructure from continuing operations would have been $637 million (unaudited) and the income for the year from continuing operations would have been $163 million (unaudited). Brookfield Infrastructure consider these pro-forma numbers to represent an approximate measure of the performance of the combined group on an annualized basis and to provide a reference point for comparison in future periods. In determining the pro-forma revenue and income, management has:

Brookfield Infrastructure's exposure to interest rate risk and a sensitivity analysis for financial assets and liabilities is disclosed in note 36.

Brookfield Infrastructure is exposed to normal credit risk with respect to its accounts receivable and maintains provisions for potential credit losses. Potential for such losses is mitigated because there is no significant exposure to any single customer and because customer creditworthiness is evaluated before credit is extended.

As of each reporting date presented above, there were no material provisions for uncollectible amounts netted to the carrying amount, nor were there any significant amounts past due.

As part of its strategy of participating in Brookfield sponsored partnerships to acquire interests in infrastructure assets in which Brookfield has significant influence or control, Brookfield Infrastructure invested with a Brookfield sponsored infrastructure fund to acquire certain assets.

During the year, through a Brookfield sponsored infrastructure fund, Brookfield Infrastructure acquired an interest in its North American hydro generation facility and increased its investment in the Texas electricity transmission project for $11 million and $2 million, respectively.

From December 2009 until its final close in September 2010, the Brookfield sponsored infrastructure fund periodically admitted new limited partners which resulted in a reduction in Brookfield Infrastructure's ownership interests in these assets. In addition, Brookfield Infrastructure sold an approximate 1% interest in its Australian coal terminal operation to a new limited partner. In conjunction with these transactions, Brookfield Infrastructure received approximately $54 million, representing the original cost of the investment plus a notational interest charge.

In the prior year, Brookfield Infrastructure acquired a portion of its interest in the Australian coal terminal operation, as well as its interest in the Texas electricity transmission project through a Brookfield sponsored infrastructure fund.

Brookfield Infrastructure's property, plant and equipment are accounted for under the revaluation method, which requires that assets be carried at their revalued amounts, being the fair value as of the date of the revaluation less any subsequent accumulated depreciation and accumulated impairment losses. The date of revaluation for these assets was December 31, 2010 and 2009.

As at December 31, 2010 and 2009, Brookfield Infrastructure carried out a review of the fair value of its U.S. and Canadian freehold timberlands' property, plant and equipment. The review led to the recognition of a loss from revaluation of $139 million (2009: loss from revaluation of $93 million),

which has been recognized in the Statements of Operating Results. The recoverable amount of the relevant property, plant and equipment has been determined on the basis of their value-in-use. The discount rate used in measuring value-in-use was a range of 6.25 to 7.50% per annum. The discount rate used when the recoverable amount of these assets was previously estimated in 2009 was a range of 6.00 to 6.15% per annum.

Brookfield Infrastructure's property, plant and equipment includes that of its North American electricity transmission operation. On each revaluation date, Brookfield Infrastructure determined fair value at that date to be equal to depreciated replacement cost by considering the current replacement cost of transmission assets and the expected useful lives of existing assets. In both 2010 and 2009, the replacement costs of the transmission assets was determined to be equivalent to their carrying value, therefore no gains or losses on revaluation was recorded.

Brookfield Infrastructure's property, plant and equipment acquired as part of the acquisition of Prime, include its Australian railroad operation, Australian energy distribution operation, and European energy distribution operation. Brookfield Infrastructure concluded that at December 31, 2010, there was no material change in the fair value of the property, plant and equipment as determined as a part of the business combination. No fair value adjustments were recorded.

Brookfield Infrastructure's property, plant and equipment include its UK port operation acquired through a business combination in November 2009. Under IFRS 3R, the provisional fair values should be revisited up to 12 months after the date of acquisition, and where appropriate the fair values should be adjusted. In November 2010, land and buildings was revalued with the assistance of an external firm of chartered surveyors. Land is valued either on a depreciated replacement cost basis for specialist property where the assets would not expect to be sold individually, or at market value where they can be sold individually. The revaluation was performed on November 20, 2010, as a part of the finalization of the business combination accounting. As a result, a loss of $33 million was recorded in the Statements of Operating Results for the year ended December 31, 2010.

The review led to the recognition of a gain from revaluation of $139 million (2009: loss from revaluation of $56 million) in Brookfield Infrastructure's U.S. and Canadian freehold timberlands, which has been recognized in the Statements of Operating Results. The recoverable amount of the standing timber has been determined on the basis of their fair value. The discount rate used in measuring value-in-use was a range of 6.25 to 7.50% per annum. The discount rate used when the recoverable amount of these assets was previously estimated in 2009 was a range of 6.00 to 6.15% per annum.

Brookfield Infrastructure's investment property portfolio carried at $175 million (2009: $175 million; Opening 2009: $41 million) is comprised of property held by its UK port operation, in addition to Canadian and U.S. freehold timberlands. Investment property held by Brookfield Infrastructure's UK Port operation is comprised of properties that are leased to third parties. Each lease contains an initial non-cancellable period and subsequent renewals are negotiated with the lessee. No contingent rents are charged. Investment property held by Brookfield Infrastructure's U.S. and Canadian freehold timberlands is comprised of land which has been determined to have a higher and better use and which is no longer used for the harvest and growth of timber.

Investment property held by the UK port operation was acquired through a business combination in November 2009. Under IFRS 3R, the provisional fair values should be revisited up to 12 months after the date of acquisition, and where appropriate the fair values should be adjusted. In November 2010, a valuation of Brookfield Infrastructure's UK port operation's investment property was determined with the assistance of an external firm of chartered surveyors. The valuation, which conforms to International Valuation Standards, utilized an open market existing use basis, by reference to market evidence of transaction prices for similar properties. The gain on revaluation of $8 million (2009: $nil) was recognized in the Statements of Operating Results.

U.S. and Canadian freehold timberlands have no restrictions on the realizability of their investment property and no contractual obligations to either purchase, construct or develop investment property or for repairs, maintenance and enhancements. Investment properties are stated at fair value,

as determined with the assistance of an accredited independent valuation company, as at December 31, 2010 and 2009 and January 1, 2009.

Upon acquisition of U.S. freehold timberlands by Brookfield Infrastructure, a future tax obligation of approximately $591 million was recorded. The deferred tax liability arose because tax bases of the net assets, to Brookfield, were significantly lower than their fair value. The inclusion of this liability in the net book value of the acquired business gave rise to goodwill of approximately $591 million, which is viewed to be recoverable so long as the tax circumstances that gave rise to the goodwill do not change. These tax circumstances will be reviewed on a periodic basis, and the goodwill balance will be reduced if necessary. To date, no such changes have occurred. The functional currency of U.S. freehold timberlands is the same as the presentation currency of Brookfield Infrastructure's financial statements, and as such no foreign exchange differences arise.

(1): The conservancy right was acquired as part of the acquisition of its UK port operations in 2009 and was recorded at its fair value. The conservancy asset recognized is not amortized as it is a right in perpetuity with an indefinite life, but is subject to an annual impairment review.
(2): Concession arrangements consist of the service concession arrangement at Brookfield Infrastructure's Australian coal terminal operation. The service concession is awarded by Governmental authorities in that jurisdiction and it allows for the use and operations of the Australian coal terminal. The terms and conditions of access to the Australian coal terminal's services, including tariffs that can be charged to the users, are regulated by the QCA. Brookfield Infrastructure's Australian coal terminal operation has Standard Access Agreements with the users of the terminal which entails 100% take or pay contracts at a designated tariff rate based on the asset value, and therefore revenue is not impacted by actual throughput. The concession arrangement has an expiration date of 2051 and with an option to extend the arrangement. These arrangements are being amortized over their useful life, with the expense recognized in the Statements of Operating Results.

Brookfield Infrastructure's exposure to currency and liquidity risk related to trade and other payables is disclosed in note 36.

Deferred revenue relates primarily to Brookfield Infrastructure's Australian railroad operation and consists of cash contributions from third parties to build or upgrade existing network capabilities. The deferred revenue is recorded on receipt of cash payments and recognized as revenue over the life of the contracted track access arrangement with the contributor.

Brookfield Infrastructure's UK port operation is involved in an industry wide representative legal action in relation to the Pilots National Pension Fund ("PNPF"), a defined benefit pension scheme which covers marine pilots in the UK, including self employed pilots. The Scheme is in a significant deficit and is seeking to levy deficit contributions on Harbour Authorities who authorize self employed pilots but do not employ them, such as Brookfield Infrastructure's UK port operation. On June 29, 2010, a judgment was issued ruling the Trustees can levy such contributions. Brookfield Infrastructure's UK port operation has appealed the ruling and recorded a provision of $38 million (2009: $39 million; Opening 2009: $nil), which represents Brookfield Infrastructure's share of the scheme's deficit as determined by the trustee. In the event of an unsuccessful appeal, we expect the liability would be funded over a period of up to 20 years.

Each preferred share is non-voting preferred and is redeemable at $25 per share together with any accrued and unpaid dividends at the option of the issuer on or after the tenth anniversary of the date of issue, subject to certain restrictions, and that entitle the holder thereof to a fixed cumulative 6% preferential cash dividend payable quarterly as and when declared by the issuer's board of directors. At December 31, 2010, there are no dividends in arrears.

As part of the acquisition of Prime (as described in note 7) Brookfield Infrastructure acquired an interest in the disposal groups AET&D and CSC. On acquisition Brookfield Infrastructure classified AET&D and CSC as assets held for sale assets with a nil carrying value.

In conjunction with the Prime re-capitalization (November 2009) Prime issued an option to the holders of exchangeable preference shares in Prime to receive any proceeds in relation to the disposal of the AET&D assets, and a 12 month option (with an option in favor of Brookfield) for a further two periods of 12 months each) was issued to Brookfield to acquire CSC for nominal proceeds. In November 2010, Brookfield extended their option for a further 12 months.

Brookfield is actively marketing both disposal groups for sale and is targeting to complete a sale of both AET&D and CSC within the next 12 months.

The major classes of assets and liabilities comprising the businesses classified as held for sale are as follows:

IFRS 8 Operating Segments, requires operating segments to be determined based on internal reports that are regularly reviewed by the Executive Management and the Board of Directors for the purpose of allocating resources to the segment and to assessing its performance. Key measures used by the Chief Operating Decision Maker in assessing performance and in making resource allocation decisions are funds from operations ("FFO") and earnings before interest, tax, depreciation and amortization ("EBITDA"), measures not defined by IFRS, which enable the determination of cash return on the equity deployed. FFO is calculated as net income excluding the impact of depreciation and amortization, fair value adjustments, unrealized gains or losses on derivative instruments, deferred taxes, interest charges and fair value adjustments on redeemable partnership units and other non-cash items. EBITDA is calculated as FFO excluding the impact of interest and taxes.

No operating segments have been aggregated to form the above reportable operating segments.

The following table provides each segment's results in the format that management utilizes to make operating decisions and assess performance.

For the purpose of monitoring segment performance and allocating resources between segments, Brookfield Infrastructure's Executive Management and Board of Directors monitor the assets and liabilities, including investments accounted for using the equity method, attributable to each segment.

For this purpose, all liabilities apart from current tax and deferred tax liabilities and intercompany loans are allocated to reportable segments; these tax liabilities are only monitored on a group level.

The following is an analysis of Brookfield Infrastructure's assets and liabilities by reportable operating segment for the years under review:

Brookfield Infrastructure has no revenues from any one major customer which is higher than 10% of Brookfield Infrastructure's total revenues.

In the normal course of operations, Brookfield Infrastructure entered into the transactions below with related parties on market terms. These transactions have been measured at fair value and are recognized in the financial statements.

The immediate parent of Brookfield Infrastructure is the general partner of the partnership. The ultimate parent of Brookfield Infrastructure is Brookfield. Other related parties of Brookfield Infrastructure represent its subsidiary and operating entities.

Details of the percentage of ownership held in subsidiaries are disclosed in note 2.

Details of the percentage of ownership held in associates are disclosed in note 12.

Transactions and balances between the partnership and its subsidiaries which are related parties of the partnership have been eliminated in full in the preparation of consolidated and combined financial statements of Brookfield Infrastructure and are not disclosed in this note. Details of transactions between Brookfield Infrastructure and other related parties are disclosed below.

Throughout the year, the immediate parent company, in its capacity as the partnership's general partner, incurs director fees, a portion of which are charged to the partnership in accordance with the limited partnership agreement.

On June 11, 2010, Brookfield Infrastructure acquired Brookfield's (its ultimate parent company's) remaining 16% interest in its UK Port operation, for approximately $27 million. The purchase price represented the original cost of the investment plus a notional interest charge. Brookfield Infrastructure's pro-rata interest was increased from 51% to 67%.

Since inception, Brookfield Infrastructure had a management agreement with its external managers, wholly owned subsidiaries of Brookfield.

Pursuant to the Master Services Agreement, on a quarterly basis, Brookfield Infrastructure pays a base management fee, referred to as the Base Management Fee, to the Manager equal to 0.3125% (1.25% annually) of the market value of the partnership.

For purposes of calculating the Base Management Fee, the market value of the partnership is equal to the volume weighted average of the closing prices of the partnership's units on the NYSE (or other exchange or market where the partnership's units are principally traded) for each of the last five trading days of the applicable quarter multiplied by the number of issued and outstanding units of the partnership on the last of those days (assuming full conversion of Brookfield's interest in Brookfield Infrastructure into units of the partnership), plus the amount of third-party debt, net of cash, with recourse to the partnership, Brookfield Infrastructure, the Holding LP and certain holding entities held directly by the Holding LP.

During the year, $16 million was reimbursed to a related party. These amounts represent third party costs that were paid for by Brookfield on behalf of Brookfield Infrastructure relating to general and administrative expenses, and acquisition related expenses of Brookfield Infrastructure. These expenses were charged to Brookfield Infrastructure at cost.

Brookfield Infrastructure has placed funds on deposit with a related party. Interest earned on the deposits is at market terms. At December 31, 2010, Brookfield Infrastructure's deposit balance with its immediate parent was $nil (2009: $50 million) and earned interest of less than $1 million for the year (2009: less than $1 million), at a rate of 0.625%.

Our North American electricity transmission operation has provided advances to and received advances from related parties in the normal course of operations. Brookfield Infrastructure's North American electricity transmission operation has also provided advances to and received advances from other divisions of Great Lakes Power Limited, an entity under common control. These advances are non-interest bearing, unsecured and due on demand. At year end $nil was due from Brookfield Infrastructure's North American electricity transmission operation (2009: $nil) and $2 million was due to Brookfield Infrastructure's North American electricity transmission operation (2009: $nil).

The amounts outstanding are unsecured and will be settled in cash. No guarantees have been given or received, and no expense has been recognized in the current or prior periods for bad or doubtful debts in respect of amounts owned by related parties.

An analysis of Brookfield Infrastructure's revenue for the year from continuing operations is as follows:

The partnership has no employees, therefore Brookfield Infrastructure does not remunerate key management personnel. Key decision makers of Brookfield Infrastructure are all employees of the ultimate parent company who provide management services under Brookfield Infrastructure's Master Services Agreement.

For the year ended December 31, 2010, payroll expense at Brookfield Infrastructure's subsidiaries was $112 million (2009: $25 million).

In September 2008, Brookfield Infrastructure exercised an option to sell its minority interest in Transmissoras Brasileiras De Energia ("TBE") to a Brazilian state owned utility. On June 30, 2009, the sale of the TBE interests was completed and Brookfield Infrastructure received proceeds of $244 million. Brookfield Infrastructure had entered into a foreign exchange hedge to lock in the projected proceeds in U.S. dollars in 2008. During 2009, Brookfield Infrastructure recorded a loss of $9 million from hedge settlements; however, since inception of the hedge program a total gain of $19 million was recorded within partnership capital. The sale of TBE resulted in the recognition of a $68 million after tax gain on sale over book value, which includes gains recorded on the foreign exchange hedge which were released from accumulated other comprehensive income.

The partnership is a flow-through entity for tax purposes and as such is not subject to Bermudan taxation. However, income taxes are recognized for the amount of taxes payable by the partnership's corporate subsidiaries and for the impact of deferred tax assets and liabilities related to such subsidiaries.

In addition, pursuant to the Master Service Agreement, on a quarterly basis, Brookfield Infrastructure pay a base management fee to the Manager equal to 0.3125% per quarter (1.25% annually) of the market value of the partnership. Based on the market value of the partnership as of December 31, 2010, this fee is estimated to be approximately $40 million per annum (2009—$20 million).

Brookfield Infrastructure offers pension plans to employees of its subsidiaries. Brookfield Infrastructure's obligations under its defined benefit pension plans are determined periodically through the preparation of actuarial valuations. The benefit plans' expense for 2010 was $9 million (2009—

$Nil). The discount rate used was 5.5% (2009: 6.2%) with an increase in the rate of compensation of 4.1% (2009: 3.8%) and an investment rate of 6.2% (2009: 7.0%).

The weighted average number of general partnership units outstanding for the year ended December 31, 2010 was 1.1 million (2009: 0.5 million). The weighted average number of limited partnership units outstanding for the year ending December 31, 2010 was 108.8 million (2009: 47.2 million).

Brookfield Infrastructure's capital structure is comprised of two classes of partnership units: general partnership units and limited partnership units.

Limited partnership units entitle the holder to their proportionate share of distributions. The Holding LP has issued 43.3 million redeemable partnership units to Brookfield, which may, at the request of the holder, require the Holding LP to redeem the units at the market price of the partnership. This right is subject to the partnership's right of first refusal which entitles it, at its sole discretion, to elect to acquire any unit so presented to the Holding LP in exchange for one of the partnership's units (subject to certain customary adjustments). Brookfield's aggregate limited

partnership interest in the partnership would be 28% if Brookfield exercised its redemption right in full and the partnership fully exercised its right of first refusal. As the partnership, at its sole discretion, has the right to settle the obligation with limited partnership units, the redeemable partnership units are classified as limited partnership units of Brookfield Infrastructure.

General partnership units entitle the holder the right to govern the financial and operating policies of Brookfield Infrastructure. Further, in its capacity as the general partner of the Holding LP, the general partner is entitled to incentive distribution rights which are based on the amount by which quarterly distributions on the limited partnership units exceed specified target levels. To the extent distributions on limited partnership units exceed $0.305 per quarter, the incentive distribution rights are entitled to 15% of incremental distributions above this threshold. To the extent that distributions on limited partnership units exceed $0.33 per unit, the incentive distribution rights are entitled to 25% of incremental distributions above this threshold.

On March 31, June 30, September 30 and December 31, 2010, a quarterly distribution of $0.275 per unit (total distribution of $117 million) was paid to the partnership unitholders. In 2009, a quarterly distribution of $0.265 per partnership unit was paid (total distribution of $59 million).

The Board of the partnership recognizes that risk management is an integral part of good management practice.

Through the management services contract, the partnership's treasury function provides services and advice to the corporate head office and also to the partnership's subsidiaries and associates across a broad range of treasury activities that assist with the management of the financial risks relating to the operations of Brookfield Infrastructure.

The treasury function is governed by a Treasury Policy as approved by the Board. This policy provides written principles on the use of financial derivatives. With respect to its Treasury Policy, senior management of Brookfield Infrastructure's external manager perform the monitoring, review and approval role and report to the Board on a regular basis.

Brookfield Infrastructure seeks to minimize the risks associated with foreign currency exchange rates and interest rates primarily through the use of derivative financial instruments to hedge these risk exposures. The use of financial derivatives is governed by the partnership's Treasury Policy. The partnership does not enter into, or trade financial instruments, including derivative financial instruments, for speculative purposes.

The operations of Brookfield Infrastructure expose it to a number of financial risks, including:

Brookfield Infrastructure manages its capital structure to be able to continue as a going concern while maximizing the return to stakeholders. Brookfield Infrastructure's overall capital strategy remains unchanged from 2009.

The capital structure of Brookfield Infrastructure consists of debt, offset by cash and cash equivalents, and partnership capital comprised of issued capital and accumulated losses.

The Board, along with senior management of the manager, reviews Brookfield Infrastructure's capital structure and as part of this review, considers the cost of capital and the risk associated with each class of capital.

Brookfield Infrastructure manages its debt exposure by financing its operations on a non-recourse basis with prudent levels of debt, ensuring a diversity of funding sources as well as laddering its maturity profile to minimize refinance risk. Brookfield Infrastructure also strives to borrow in the currency where the asset operates, where possible, in order to hedge its currency risk.

Generally, Brookfield Infrastructure's equity strategy is to issue equity in conjunction with future acquisitions. However, Brookfield Infrastructure may also issue an amount of equity opportunistically to enhance its liquidity to pursue investments. In December 2009, Brookfield Infrastructure filed shelf registrations to enable it to issue securities in both the U.S. and Canadian markets.

Brookfield Infrastructure's financing plan is to fund its recurring growth capital expenditures with cash flow generated by its operations after maintenance capital expenditure, as well as debt financing that is sized to maintain its credit profile. To fund large scale development projects and acquisitions, the partnership will evaluate a variety of capital sources including proceeds from selling non-core assets, equity and debt financing. The partnership will seek to raise additional equity if Brookfield Infrastructure believes it can earn returns on these investments in excess of the cost of the incremental partnership capital.

As disclosed within borrowings (note 20), the partnership has various loan facilities in place. In certain cases, the facilities have financial covenants which are generally in the form of interest cover ratios and leverage ratios. Brookfield Infrastructure does not have any market capitalization covenants attached to any of its borrowings, nor does it have any other externally imposed capital requirement.

During the years ended December 31, 2010 and 2009, there were no breaches of any loan covenants within Brookfield Infrastructure.

Brookfield Infrastructure attempts to maintain sufficient financial liquidity at all times so that it is able to participate in attractive opportunities as they arise, better withstand sudden adverse changes in economic circumstances and maintain a relatively high distribution of its FFO to unitholders. Brookfield Infrastructure's principal sources of liquidity are cash flows from its operations, undrawn credit facilities and access to public and private capital markets. Brookfield Infrastructure also structures the ownership of its assets to enhance its ability to monetize them to provide additional liquidity, if necessary.

Brookfield Infrastructure's estimated corporate liquidity as at December 31, is as follows:

Brookfield Infrastructure's $700 million committed revolving credit facility is available for investments and acquisitions, as well as general corporate purposes. Commitments under the facility will be available on a revolving basis until June 2013. All amounts outstanding at that time will be repayable in full. The facility is intended to be a bridge to equity financing rather than a permanent source of capital. At December 31, 2010, $18 million was drawn on this facility.

The following tables detail the contractual maturities for Brookfield Infrastructure's financial liabilities. The tables reflect the undiscounted cash flows of financial liabilities based on the earliest date on which Brookfield Infrastructure can be required to pay.

Brookfield Infrastructure's primary objectives with respect to interest rate risk management are to ensure that:

To achieve these objectives, in general terms, Brookfield Infrastructure's funding mix comprises both fixed and floating rate debt. Fixed rate debt is achieved either through fixed rate debt funding or through the use of financial derivate instruments. In addition, where possible, interest rate risk is minimized by matching the terms of interest rate swap contracts in regulated businesses to the term of the rate period, thus providing natural hedges.

The sensitivity analyses below reflect Brookfield Infrastructure's exposure to interest rates for both derivative and non-derivative instruments at the reporting date, assuming that a 50 basis point increase or decrease in rates takes place at the beginning of the financial year and is held constant throughout the reporting period. A 50 basis point change in interest rates is the sensitivity used internally when assessing interest rates. Such parallel shift in the yield curve by 50 basis points would have had the following impact, assuming all other variables were held constant:

Brookfield Infrastructure's sensitivity to interest rates increased during the year due to the acquisition of Prime. However, Brookfield Infrastructure entered into interest rate swap contracts (as described below) to mitigate the impact on comprehensive income.

Under interest rate swap contracts, Brookfield Infrastructure agrees to exchange the difference between fixed and floating rate interest payments calculated on agreed notional principal amounts. Such contracts enable Brookfield Infrastructure to mitigate the risk of changing interest rates on the its variable rate debt. The fair value of interest rate swaps at the reporting date is determined by discounting their future cash flows with the applicable benchmark interest rate curve and is disclosed below. The average interest rate is based on the debt outstanding balances at the end of the reporting period.

The following tables detail the notional principal amounts and remaining terms of Brookfield Infrastructure's interest rate swap contracts outstanding as at the reporting date:

Interest rate swap contracts are designated as cash flow hedges in order to reduce Brookfield Infrastructure's cash flow exposure to variable interest rates. The settlement dates typically coincide with the dates on which the interest is payable on the underlying debt, and the amount accumulated in equity is reclassified to income or loss over the period that the floating rate interest payments on debt affect income or loss. During the year, Brookfield Infrastructure recognized an amount of $8 million in other comprehensive income in relation to the fair value movement of the swaps (2009: $nil). The ineffectiveness recorded in the Statements of Operating Results was $(3) million in 2010 (2009: $nil).

Certain interest rate contracts do not qualify for hedge accounting and are not able to be treated as cash flow hedges.

A subsidiary of the partnership has entered into a number of inflation swaps. The purpose of these derivatives is to hedge the proportion of the pre-finance cash flows deemed to be inflation linked. These derivatives do not qualify for hedge accounting and are not able to be treated as cash flow hedges.

During the year, Brookfield Infrastructure recognized $4 million in the Statements of Operating Results in 2010 (2009: $nil) relating to the fair value movement of the swaps.

Brookfield Infrastructure has exposure to foreign currency risk in respect of currency transactions, the value of Brookfield Infrastructure's net investment, cash flows and capital expenditures that are denominated outside of the U.S.. Brookfield Infrastructure's approach to foreign currency risk management is:

Brookfield Infrastructure uses forward foreign exchange contracts to hedge its net investment in foreign entities. The following table details the forward foreign currency contracts outstanding at the end of the reporting period.

During the year, Brookfield Infrastructure recognized an amount of ($18 million) (2009: $nil) in other comprehensive income relating to the fair value movement of the swaps. Further, Brookfield Infrastructure recognized an amount of ($33 million) (2009: $nil) in other comprehensive income relating to the net settlement of foreign exchange contracts in the period.

From time to time, Brookfield Infrastructure will purchase an option to purchase foreign exchange at contracted rates to mitigate potential significant cash outflows arising on the short positions noted above. As at December 31, 2010, Brookfield Infrastructure had an option contract of A$125 million with a fair value of $3 million (2009: $nil).

From time to time, Brookfield Infrastructure will enter into forward foreign exchange contracts to mitigate foreign exchange risk on expected future cash inflows or outflows denominated in a foreign currency. As at December 31, 2010, Brookfield Infrastructure had no forward foreign exchange contracts to mitigate foreign exchange risk on expected future cash flows. As at December 31, 2009, Brookfield Infrastructure had forward foreign exchange contracts to mitigate a notional balance of £8 million with a fair value of $1 million.

The following tables detail Brookfield Infrastructure's sensitivity to a 10% increase and decrease in the U.S. dollar against the relevant foreign currencies, with all other variables held constant as at reporting date. 10% is the sensitivity rate used when reporting foreign currency risk internally. The sensitivity analysis is performed as follows:

Credit risk refers to the risk that counterparty will default on its contractual obligations resulting in financial loss to the partnership. Brookfield Infrastructure only undertakes transactions with credit worthy customers and conducts active ongoing credit evaluation on the financial condition of customers and other accounts receivable in order to minimize credit risk.

From a treasury perspective, counterparty credit risk is managed through the establishment of authorized counterparty credit limits which ensure that the partnership only deals with credit worthy counterparties and that counterparty concentration is addressed and the risk of loss is mitigated. Credit limits are sufficiently low to restrict the partnership from having credit exposures concentrated with a single counterparty but rather encourages spreading such risks among several parties. The limits are set at levels that reflect the partnership's scale of activity and allow it to manage its treasury business competitively.

The partnership does not have any significant credit risk exposure to any single counterparty or any group of counterparties having similar characteristics. The credit risk on liquid funds and derivative financial instruments is limited because the counterparties are banks with high credit ratings assigned by international credit-rating agencies.

The fair value of financial assets and liabilities that are traded on active liquid markets are determined with reference to quoted market prices:

Except as detailed in the following tables, the Directors consider that the carrying amounts of financial assets and liabilities recorded at amortized cost in the financial statements of Brookfield Infrastructure approximate their fair values.

	2010				2009

US$ MILLIONS	Carrying amount		Fair value		Carrying amount		Fair value
Financial liabilities
Prime Secured bonds	$	113	$	113	$	—	$	—

The table below analyzes financial instruments carried at fair value, by valuation method. The different levels have been defined as follows:

Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2: inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices).

Level 3: inputs for the assets or liability that are not based on observable market data (unobservable inputs).

There were no transfers between levels during the year ended December 31, 2010 and 2009.

Amounts paid and received for interest were reflected as operating cash flows in the consolidated and combined Statements of Cash Flows. Interest paid is net of debt related hedges.

Amounts paid for income taxes were reflected as either operating cash flows or investing cash flows in the consolidated and combined Statements of Cash Flow depending upon the nature of the underlying transaction.

In February 2011, Brookfield Infrastructure refinanced $600 million of debt maturing in 2011, issued by its Australian coal terminal operation. Brookfield Infrastructure priced a U.S. private placement comprised of two tranches on February 16, 2011, with $300 million at 9 years and $300 million at 12 years with a fixed coupon rate of 5.23% and 5.57%, respectively. In conjunction, Brookfield Infrastructure entered into a series of cross currency and interest rate swaps that effectively swapped these notes to an AUD fixed rate of 7.5% and 7.7%, respectively. The 12-year tranche closed in March 2011 and the 9-year tranche is expected to close at the end of April 2011.

Strategic Position:		The Bowen Basin is one of the lowest cost and most prolific series of coal deposits in the world; there are few options to access export markets for this coal other than through our Australian coal terminal operations. With completion of its recent Stage 7 expansion, our Australian coal terminal operations have a capacity of 85 million tons per year, or mtpa.
Regulatory Environment:		Our Australian coal terminal operations are regulated by the Queensland Competition Authority, or QCA. The current rate agreement commenced on January 1, 2011 and expires on June 30, 2016.
Customer Base:		Our Australian coal terminal operations have long-term take-or-pay contracts with some of the world's largest mining companies that operate in the Bowen Basin.


Strategic Position:		Our Australian railroad operations are the only rail network in the southwest region of WA providing access to the region's six ports for minerals, grain and interstate intermodal traffic.
Regulatory Environment:		The Economic Regulatory Authority has established an access regime which governs track segment revenue ceilings and floors, train management, train paths, and confidentiality. However, all of our Australian railroad operations' customers have negotiated their below-rail access agreements outside of the access regime, meaning that the regulatory ceilings do not apply.


Strategic Position:		Our European port operations are positioned in 16 locations across continental Europe and consist of 485 hectares of long-term port concessions and over 31 km of quay length. With extensive infrastructure in place, including cranes, berths, warehouses, inloading and outloading equipment, our European port operations provide extensive logistics services to its customers, creating barriers to entry.
