Corporate Information And Statement Of IFRS Compliance [Abstract]
ORGANIZATION AND DESCRIPTION OF THE BUSINESS	ORGANIZATION AND DESCRIPTION OF THE BUSINESS a) Brookfield Infrastructure Partners L.P. Brookfield Infrastructure Partners L.P. (our “partnership” and, together with its subsidiaries and operating entities, “Brookfield Infrastructure”) owns and operates utilities, transport, midstream and data businesses in North and South America, Europe and the Asia Pacific region. Our 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. Our partnership is a subsidiary of Brookfield Corporation (“Brookfield”). Our partnership’s units are listed on the New York Stock Exchange and the Toronto Stock Exchange under the symbols “BIP” and “BIP.UN”, respectively. Our cumulative Class A preferred limited partnership units, Series 1, Series 3, Series 9 and Series 11 are listed on the Toronto Stock Exchange under the symbols “BIP.PR.A”, “BIP.PR.B,” “BIP.PR.E,” and “BIP.PR.F”, respectively. Our cumulative Class A preferred limited partnership units, Series 13 and Series 14, are listed on the New York Stock Exchange under the symbols “BIP.PR.A” and “BIP.PR.B,” respectively. Our partnership’s registered office is 73 Front Street, 5th Floor, Hamilton HM 12, Bermuda. In these notes to the consolidated financial statements, references to “units” are to the limited partnership units in our partnership other than the preferred units, references to our “preferred units” are to preferred limited partnership units in our partnership and references to our “unitholders” and “preferred unitholders” are to the holders of our units and preferred units, respectively. References to “Class A Preferred Units,” “Series 1 Preferred Units,” “Series 3 Preferred Units,” “Series 9 Preferred Units,” “Series 11 Preferred Units,” “Series 13 Preferred Units,” and “Series 14 Preferred Units” are to cumulative Class A preferred limited partnership units, cumulative Class A preferred limited partnership units, Series 1, cumulative Class A preferred limited partnership units, Series 3, cumulative Class A preferred limited partnership units, Series 9, cumulative Class A preferred limited partnership units, Series 11, cumulative Class A preferred limited partnership units, Series 13, and cumulative Class A preferred limited partnership units, Series 14, in our partnership, respectively. b) Brookfield Infrastructure Corporation On August 30, 2019, Brookfield Infrastructure Corporation (“BIPC”) was established by the partnership. On March 30, 2020, the partnership contributed our U.K. regulated distribution operation and Brazilian regulated gas transmission operation to BIPC. On March 31, 2020, the partnership completed a special distribution (the “special distribution”) whereby unitholders as of March 20, 2020 (the “Record Date”) received one class A exchangeable subordinate voting share (“BIPC exchangeable share”) for every nine units held. Immediately prior to the special distribution, the partnership received exchangeable shares through a distribution by Brookfield Infrastructure L.P. (“Holding LP”), or the Holding LP Distribution, of the BIPC exchangeable shares to all of its unitholders. As a result of the Holding LP Distribution, (i) Brookfield and its subsidiaries received approximately 13.7 million BIPC exchangeable shares and (ii) the partnership received approximately 32.6 million BIPC exchangeable shares, which it subsequently distributed to unitholders pursuant to the special distribution. Immediately following the special distribution, (i) holders of units held approximately 70.4% of the issued and outstanding BIPC exchangeable shares (ii) Brookfield and its affiliates held approximately 29.6% of the issued and outstanding BIPC exchangeable shares, and (iii) a subsidiary of the partnership owned all of the issued and outstanding class B multiple voting shares, or class B shares, which represent a 75.0% voting interest in BIPC, and all of the issued and outstanding class C non-voting shares, or class C shares, of BIPC, which entitle the partnership to the residual value in BIPC after payment in full of the amount due to holders of BIPC exchangeable shares and class B shares. The partnership directly and indirectly controlled BIPC prior to the special distribution and continues to control BIPC subsequent to the special distribution through its interests in the company. The BIPC exchangeable shares are listed on the New York Stock Exchange and the Toronto Stock Exchange under the symbol “BIPC”. i) BIPC exchangeable shares At any time, holders of BIPC exchangeable shares have the right to exchange all or a portion of their BIPC exchangeable shares for one unit per BIPC exchangeable share held or its cash equivalent based on the NYSE closing price of one unit on the date that the request for exchange is received, on a fixed-for-fixed basis. BIPC or the partnership, as applicable, has the ability to satisfy exchanges of BIPC exchangeable shares in units instead of cash. Additionally, the partnership has the ability to exchange all BIPC exchangeable shares for units at our election, on a fixed-for-fixed basis. As a result of these characteristics, BIPC exchangeable shares have been classified as non-controlling interests in the Consolidated Statements of Financial Position. ii) Basic and diluted income per unit The special distribution resulted in the issuance of approximately 69.5 million exchangeable shares. Historical per unit/share disclosures have been retroactively adjusted to effect for the special distribution. On June 10, 2022, Brookfield Infrastructure completed a three-for-two split of our units, BIPC exchangeable shares, Exchange LP Units, and BIPC exchangeable LP units, by way of a subdivision whereby unitholders/shareholders received an additional one-half of a unit/share for each unit/share held. The Managing General Partner Units, Special General Partner Units and Redeemable Partnership Units of the Holding LP were concurrently split. Brookfield Infrastructure’s preferred units were not affected by the split. All historical unit and share counts, as well as per unit/share disclosures have been adjusted to effect for the change in units as a result of the splits. c) Brookfield Infrastructure Corporation Exchange Limited Partnership On April 21, 2021, Brookfield Infrastructure Corporation Exchange Limited Partnership (“BIPC Exchange LP”) was established by the partnership. In connection with the acquisition of Inter Pipeline Ltd. (“IPL,” “Inter Pipeline,” or “Canadian diversified midstream operation”), certain IPL shareholders were given the right to elect to receive, for each common share of IPL and in lieu of cash consideration, 0.25 BIPC exchange LP class B exchangeable limited partnership units (“BIPC exchangeable LP units”), or 0.25 BIPC exchangeable shares. The BIPC exchangeable LP units provide holders with economic terms that are substantially equivalent to those of a BIPC exchangeable share and are exchangeable, on a one-for-one basis, for BIPC exchangeable shares. Given the exchangeable features, we present the BIPC Exchangeable LP units as a component of non-controlling interest.

Our partnership controls these investees given that our partnership is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Our partnership exercises judgment to determine the level of variability that will achieve control over an investee, particularly in circumstances where our partnership’s voting interest differs from its ownership interest in an investee. The following were considered to determine whether our partnership controls these investees: the degree of power (if any) held by other investors, the degree of exposure to variability of each investor, the determination of whether any general partner removal rights are substantive and the purpose and design of the investee.

SIGNIFICANT ACCOUNTING POLICIES

SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2022
Corporate Information And Statement Of IFRS Compliance [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES (a) Statement of Compliance These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”). The consolidated financial statements were authorized for issue by the Board of Directors on March 17, 2023. (b) Basis of Preparation The consolidated financial statements are prepared on a going concern basis. (i) Subsidiaries These consolidated financial statements include the accounts of our partnership and subsidiaries over which our partnership has control. Subsidiaries are consolidated from the date of acquisition, being the date on which our partnership obtains control, and continue to be consolidated until the date when control is lost. Our partnership (investor) controls an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Together, our partnership and its subsidiaries are referred to as “Brookfield Infrastructure” in these financial statements. 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 in addition to changes in ownership interests. Total comprehensive income is attributed to non-controlling interests, even if this results in the non-controlling interests having a deficit balance. Holding LP has issued Redeemable Partnership Units held by Brookfield, which may, at the request of the holder, require the Holding LP to redeem the Redeemable Partnership Units for cash consideration equal to the market price of our partnership’s units. This right is subject to our partnership’s right of first refusal which entitles it, at its sole discretion, to elect to acquire any Redeemable Partnership Unit so presented to Holding LP in exchange for one of our partnership’s units subject to certain customary adjustments. All intercompany balances, transactions, revenues and expenses are eliminated in full. (ii) Associates and Joint Ventures Associates and joint ventures are entities over which our partnership has significant influence or joint control. Significant influence is the power to participate in the financial and operating policy decisions of the investee but does not constitute control. Our partnership accounts for investments over which it has significant influence using the equity method, and are recorded as Investments in associates and joint ventures on the Consolidated Statements of Financial Position. Interests in investments accounted for using the equity method are initially recorded at cost. If the cost of the associate is lower than the proportionate share of the investment’s underlying fair value, our partnership records a gain on the difference between the cost and the underlying fair values of the identifiable net assets of the associate. If the cost of the associate is greater than our partnership’s proportionate share of the underlying fair value, goodwill and other adjustments arising from the purchase price allocation relating to the associate is included in the carrying amount of the investment. Subsequent to initial recognition, the carrying value of our partnership’s interest in an investee is adjusted for our partnership’s share of comprehensive income or loss and distributions from the investee. Profits or losses resulting from transactions with an associate are recognized in the consolidated financial statements based on the interests of unrelated investors in the associate. (c) Foreign Currency Translation The U.S. dollar is the functional and presentation currency of Brookfield Infrastructure. Each of Brookfield Infrastructure’s subsidiaries, associates and jointly controlled entities determines its own functional currency and items included in the financial statements of each subsidiary and associate 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 other comprehensive income. On disposal of a foreign operation resulting in the loss of control, the component of other comprehensive income due to accumulated foreign currency translation relating to that foreign operation is reclassified to net income. 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. On partial disposal of a foreign operation in which control is retained, the proportionate share of the component of other comprehensive income or loss relating to that foreign operation is reclassified to non-controlling interests in that foreign operation. Foreign currency denominated monetary assets and liabilities are translated using the rate of exchange prevailing at the reporting date and 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 net income. Gains and losses on transactions which hedge these items are also included in net income or loss. Foreign currency denominated non-monetary assets and liabilities, measured at historic cost, are translated at the rate of exchange at the transaction date. (d) Business Combinations Business acquisitions in which control is acquired 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 transferred by the acquirer, liabilities incurred or assumed, and equity instruments issued by Brookfield Infrastructure in exchange for control of the acquiree. Acquisition related costs are recognized in the Consolidated Statements of Operating Results as incurred and included in other 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 the acquisition where they qualify as measurement period adjustments. All other subsequent changes in the fair value of contingent consideration classified as liabilities will be recognized in the Consolidated Statements of Operating Results, whereas changes in the fair values 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 the Consolidated Statements of Operating Results. Amounts arising from interests in the acquiree prior to the acquisition date that have previously been recognized in other comprehensive income are reclassified to the Consolidated Statements of Operating Results, 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 to the acquisition date. 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 profit or loss as a bargain purchase gain. 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 (“IAS 37”) and the amount initially recognized less cumulative amount of income recognized in accordance with IFRS 15, Revenue from Contracts with Customers . (e) Cash and Cash Equivalents Cash and cash equivalents include cash on hand and short-term, highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value. (f) Accounts Receivable Trade receivables are recognized initially at their transaction price and subsequently measured at amortized cost using the effective interest method, less any allowance for expected credit losses. (g) Inventory Inventory is valued at the lower of cost and net realizable value. Cost is determined using the weighted average costing method and includes direct purchase costs as well as costs of production, storage, and transportation of natural gas, natural gas liquids and other hydrocarbons. Net realizable value represents the estimated selling price in the ordinary course of business less estimated costs of completion and selling costs. If applicable, an increase in net realizable value representing a reversal of a previous inventory write-down is recognized as an increase in inventory. (h) Property, Plant and Equipment Brookfield Infrastructure uses the revaluation method of accounting for all classes of property, plant and equipment. Property, plant and equipment is initially measured at cost and subsequently carried at its 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 at least an annual basis, and on a sufficient 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 other comprehensive income or loss and accumulated in equity within the revaluation surplus reserve, unless the increase reverses a previously recognized impairment recorded through net income, in which case that portion of the increase is recognized in net income. 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 net income. Revaluation gains are included in other comprehensive income, but are not subsequently recycled into profit or loss. 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 the Consolidated Statements of Operating Results. However, any balance accumulated in revaluation surplus is subsequently recorded in retained earnings when an asset is derecognized and not transferred to profit or loss. Depreciation of an asset commences when it is available for use. Property, plant and equipment are depreciated on a straight-line or declining-balance basis over the estimated useful lives of each component of the assets as follows: Buildings Up to 75 years Transmission stations, towers and related fixtures Up to 40 years Leasehold improvements Up to 50 years Plant and equipment Up to 40 years Network systems Up to 65 years Track Up to 40 years District energy systems Up to 50 years Pipelines Up to 20 years Gas storage assets Up to 50 years Depreciation on property, plant and equipment is calculated on a straight-line or declining-balance basis so as to depreciate 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 methods are reviewed at the end of each annual reporting period, with the effect of any changes recognized on a prospective basis. (i) Investment Properties Brookfield Infrastructure uses the fair value method to account for assets classified as investment property. An asset 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 profit or loss. Fair values are primarily determined by valuation of the lease term and freehold reversion. An income capitalization approach is used by applying a yield to the rental income of the capitalization rate that is reflective of the characteristics, location and market of each property. Fair value is estimated by management of our partnership with due consideration given to observable market inputs, where available. (j) Asset Impairment At each reporting date, Brookfield Infrastructure assesses whether for assets, other than those measured at fair value with changes in values recorded in profit or loss, there is any indication that such assets are impaired. This assessment includes a review of internal and external factors which includes, but is not limited to, changes in the technological, political, economic or legal environment in which the entity operates in, structural changes in the industry, changes in the level of demand, physical damage and obsolescence due to technological changes. An impairment is recognized if the recoverable amount, determined as the higher of the estimated fair value less costs of disposal or the discounted future cash flows generated from use and eventual disposal from an asset or cash generating unit is less than its carrying value. The projections of future cash flows take into account the relevant operating plans and management’s best estimate of the most probable set of conditions anticipated to prevail. Where an impairment loss subsequently reverses, the carrying amount of the asset or cash generating unit is increased to the lesser of the revised estimate of recoverable amount and the carrying amount that would have been recorded had no impairment loss been recognized previously. (k) Intangible Assets Intangible assets acquired in a business combination and recognized separately from goodwill are initially recognized at their fair value at the acquisition date. Brookfield Infrastructure’s intangible assets are comprised primarily of conservancy rights, service concession arrangements, customer order backlogs, track access rights, operating network agreements and customer contracts and relationships. Subsequent to initial recognition, intangible assets acquired in a business combination are reported at cost less accumulated amortization unless indefinite-lived 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 under IFRIC 12, Service Concession Arrangements . Concession arrangements were acquired as part of the acquisition of the Brazilian regulated gas transmission operation, Brazilian electricity transmission operation and Indian and Peruvian toll roads and were initially recognized at their fair values. The intangible assets at the Brazilian regulated gas transmission operation and Brazilian electricity transmission operation relate to concession contracts. For our Brazilian regulated gas transmission operation, the concession arrangement provides the business with the right to operate the asset perpetually. As a result, the asset is amortized over its estimated useful life. For our Brazilian electricity transmission operation, the intangible asset is amortized on a straight-line basis over the life of the contractual arrangement. The intangible assets at the Indian and Peruvian toll roads relate to the right to operate a road and charge users a specified tariff for a contractual length of time and is amortized over the life of the contractual arrangement with an average of 15 and 21 years remaining, respectively. 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 profit or loss when the asset is derecognized. (l) Goodwill Goodwill represents the excess of the price paid for the acquisition of an entity over the fair value of the net tangible and intangible assets and liabilities acquired. Goodwill is allocated to the cash generating unit or units to which it relates. Brookfield Infrastructure identifies cash generating units as identifiable groups of assets that are largely independent of the cash inflows from other assets or groups of assets. Goodwill is evaluated for impairment annually or more often if events or circumstances indicate there may be impairment. Impairment is determined for goodwill by assessing if the carrying value of a cash generating unit, including the allocated goodwill, exceeds its recoverable amount determined as the greater of the estimated fair value less costs of disposal or the value in use. Impairment losses recognized in respect of a cash generating unit are first allocated to the carrying value of goodwill and any excess is allocated to the carrying amount of assets in the cash generating unit. Any goodwill impairment is charged to profit or loss in the period in which the impairment is identified. Impairment losses on goodwill are not subsequently reversed. In the year of a business acquisition, the recoverability of the acquired goodwill is assessed by revisiting the assumptions of the related underwriting model. On disposal of a subsidiary, the attributable amount of goodwill is included in the determination of the gain or loss on disposal of the operation. (m) Revenue Recognition Our partnership recognizes revenue when it transfers control of a product or service to a customer. Revenue is measured based on the consideration specified in a contract with a customer and excludes amounts collected on behalf of third parties. 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. Utilities Revenue from utilities infrastructure is derived from the transmission of energy and natural gas, and from our commercial and residential distribution operations. Distribution and transmission revenue each contain a single performance obligation that is recognized over time. The connection revenue relating to Brookfield Infrastructure’s U.K. regulated distribution operation contains a distinct performance obligation that is recognized over the period that the connection is constructed, based on an input method of progress recognition on the basis that this methodology is most reflective of the underlying transfer of control. Performance obligations relating to commercial and residential distribution operations are satisfied over time as the services are rendered or upon commencement of a finance lease agreement. The payment terms for all of our businesses in the utilities segment require payment upon completion, except for connections income whereby payment is typically collected up-front prior to the completion of any services. Transport Revenue from transport infrastructure consists primarily of freight, toll road operations, transportation services revenue, and from our Australian export terminal. These services consist of a single performance obligation and revenue is recognized over time when services are rendered, based primarily on usage or volume during the period. Terminal infrastructure revenue contains both a capacity charge and a handling charge associated with operating the terminal. The terminal infrastructure service contracts contain a performance obligation recognized over time pertaining to capacity for the period the services are provided and for handling services based on tons of coal shipped through the terminal when service is provided. The payment terms for all of our businesses in the transport segment require payment upon completion of the underlying transportation service. Midstream Revenue from midstream infrastructure consists primarily of midstream and storage services. Natural gas midstream services revenue consists of a single performance obligation and is recognized over time as services are rendered, based primarily on volume throughput or contracted capacity. Revenue associated with the sale of raw materials consists of a single performance obligation and is recognized upon delivery. Gas storage revenues contain both a capacity charge and a variable charge, however the associated services are highly interdependent and represent a single performance obligation that is satisfied over time as the services are provided. The payment terms for all of our businesses in the midstream segment require payment upon completion of the underlying service within a given period. Data Revenues from data transmission and distribution operations are derived from contracts with media broadcasting and telecom customers to access infrastructure, and revenue from data storage operations are generated from providing data storage services to enterprise customers. These contracts consist of performance obligations that are satisfied over time in accordance with the underlying agreements. The payment terms require upfront and recurring payments to utilize space on towers to host the customers’ equipment at our data transmission and distribution operations, and to receive colocation services, mainly leased space and power, at our data storage operations. The differing payment terms do not constitute separate performance obligations as revenue is recognized over time for the period the services are provided. (n) Financial Instruments and Hedge Accounting (i) Financial Instrument Classification Our partnership classifies cash and cash equivalents and accounts receivable and other as amortized cost. Additionally, our partnership maintains a portfolio of marketable securities comprised of liquid equity and debt securities. The marketable securities are classified either as fair value through other comprehensive income (“FVTOCI”) or fair value through profit or loss (“FVTPL”). Derivative assets are classified as FVTPL, except for derivatives in certain hedging relationships. Other financial assets are classified as either amortized cost or FVTOCI. Financial assets classified as FVTPL or FVTOCI are subsequently measured at fair value at each reporting date. For financial assets classified as FVTPL, the change in fair value is recorded through profit or loss. For financial assets classified as FVTOCI, the change in fair value is recorded in other comprehensive income. The cumulative gains or losses related to FVTOCI equity instruments are not reclassified to profit or loss on disposal, whereas the cumulative gains or losses on all other FVTOCI assets are reclassified to profit or loss on disposal. For financial instruments at amortized cost or debt instruments at FVTOCI, the partnership assesses if there have been significant increases in credit risk since initial recognition to determine whether lifetime or 12-month expected credit losses should be recognized. Any related loss allowances are recorded through profit or loss. Borrowings, accounts payable and other, and preferred shares are classified as amortized cost, except for derivatives embedded in related financial instruments. Embedded derivatives and any other derivative liabilities are classified as FVTPL and are subsequently measured at fair value, except for derivatives in certain hedging relationships. Other financial liabilities are classified as either FVTPL or amortized cost. (ii) Hedge Accounting Brookfield Infrastructure selectively utilizes derivative financial instruments primarily to manage financial risks, including interest rate and foreign exchange risks. Derivative financial instruments are recorded at fair value. Hedge accounting is applied when the derivative is designated as a hedge of a specific exposure and that the hedging relationship meets all of the hedge effectiveness requirements. 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 other comprehensive income by the application of hedge accounting is recognized in profit or loss over the remaining term of the original hedging relationship as amounts related to the hedged item are recognized in profit or loss. The assets or liabilities relating to unrealized mark-to-market gains and losses on derivative financial instruments are recorded in financial assets and financial liabilities, respectively. 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 equity 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 profit or loss or as a component of equity as applicable. Unrealized gains and losses on interest rate contracts designated as hedges of future variable interest payments are included in equity as a cash flow hedge when the interest rate risk relates to an anticipated variable interest payment. The periodic exchanges of payments on interest rate swap contracts designated as hedges of debt are recorded on an accrual basis as an adjustment to interest expense. (o) Income Taxes Income tax expense represents the sum of the tax accrued in the period and deferred income tax. (i) Current income 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 or substantively enacted at the reporting date. Current income tax relating to items recognized directly in partnership capital and other comprehensive income are also recognized directly in partnership capital and other comprehensive income, respectively. (ii) Deferred income tax 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 consolidated 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 income tax assets and liabilities are not recognized if the temporary difference arises from goodwill or from the initial recognition of other assets and liabilities in a transaction that affects neither the taxable income nor the accounting income, other than in a business combination. 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 income 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 income 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. 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 income tax liabilities and assets reflect 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 income 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 within a single taxable entity or Brookfield Infrastructure intends to settle its current tax assets and liabilities on a net basis in the case where there exist different taxable entities in the same taxation authority and when there is a legally enforceable right to set off current tax assets against current tax liabilities. (p) Assets Held for Sale 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 subject to limited exceptions. 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 Consolidated Sta

Operating Segments [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION IFRS 8, Operating Segments, requires operating segments to be determined based on information that is regularly reviewed by the Executive Management and the Board of Directors for the purpose of allocating resources to the segment and to assess its performance. The Chief Operating Decision Maker (“CODM”) uses Funds from Operations (“FFO”) in assessing performance and in making resource allocation decisions, which enable the determination of return on the equity deployed. To measure performance, among other measures, we focus on net income as well as FFO. We define FFO as net income excluding the impact of depreciation and amortization, deferred income taxes, mark-to-market on hedging items and other income (expenses) that are not related to the revenue earning activities and are not normal, recurring cash operating items necessary for business operations. FFO includes balances attributable to the partnership generated by investments in associates and joint ventures accounted for using the equity method and excludes amounts attributable to non-controlling interests based on the economic interests held by non-controlling interests in consolidated subsidiaries.

ACQUISITION OF BUSINESSES	ACQUISITION OF BUSINESSES Acquisitions Completed in 2022 a) Individually insignificant business combinations During the year, Brookfield Infrastructure, through its subsidiaries acquired a 17% interest in an Indian telecommunications business for approximately $30 million (consolidated total of approximately $165 million for a 100% interest), a 30% interest in five North American residential infrastructure businesses for approximately $90 million (consolidated total of approximately $315 million for a 100% interest), and an approximately 24% interest in a U.K. telecom tower portfolio for approximately $40 million (consolidated total of approximately $160 million for a 100% interest). The following table summarizes the purchase price allocation of individually insignificant business combinations that have been completed in 2022: US$ MILLIONS Cash $ 123 Equity consideration (1) 21 Contingent consideration 17 Total consideration $ 161 (1) As part of our consideration, we issued shares of a subsidiary which are compound financial instruments . Fair value of assets and liabilities acquired (provisional) (1) : US$ MILLIONS Cash and cash equivalents $ 6 Accounts receivable and other 24 Property, plant and equipment 161 Intangible assets 302 Goodwill 278 Accounts payable and other liabilities (54) Non-recourse borrowings (51) Deferred income tax liabilities (18) Net assets acquired before non-controlling interest 648 Non-controlling interest (2) (487) Net assets acquired $ 161 (1) The fair values of certain acquired assets and liabilities for these operations have been determined on a provisional basis given the proximity of the acquisitions to the reporting date, pending finalization of the determination of the fair values of the acquired assets and liabilities. Our partnership is in the process of obtaining additional information primarily in order to assess the fair values of property, plant and equipment, intangible assets, deferred income taxes and the resulting impact to goodwill as at the date of the acquisitions. (2) Non-controlling interest represents the interest not acquired by Brookfield Infrastructure, measured at fair value at the acquisition dates. Supplemental Information Had the individually insignificant acquisitions been effective January 1, 2022, the revenue and net income of Brookfield Infrastructure would have increased by approximately $81 million (unaudited) and $27 million (unaudited), respectively, for the year ended December 31, 2022. In determining the pro-forma revenue and net income attributable to our partnership, management has: • Calculated depreciation of property, plant and equipment and amortization of intangible assets acquired on the basis of the fair values at the time of the business combination rather than the carrying amounts recognized in the pre-acquisition financial statements; and • Based borrowing costs on the funding levels, credit ratings and debt and equity position of Brookfield Infrastructure after the business combination. Acquisitions Completed in 2021 (a) Acquisition of Brazilian electricity transmission operation On February 26, 2021, Brookfield Infrastructure, alongside institutional partners, exercised its option to acquire an additional 15% interest in Jose Maria de Macedo de Eletricidade S.A (“JMM”), a Brazilian electricity transmission operation, increasing Brookfield Infrastructure’s ownership in JMM to 31%. Prior to February 26, 2021, our partnership’s existing interest in JMM was accounted for using the equity method. On December 24, 2021, Brookfield Infrastructure, alongside institutional partners, exercised its option to acquire an additional 15% interest in Giovanni Sanguinetti Transmissora de Energia S.A. (“Sanguinetti”) and Veredas Transmissora de Electricidade S.A. (“Veredas”), Brazilian electricity transmission operations, increasing Brookfield Infrastructure’s ownership in both operations to 31%. Prior to December 24, 2021, our partnership’s existing interest in both operations were accounted for using the equity method. Consideration Transferred: US$ MILLIONS Cash $ 56 Pre-existing interest in the businesses 92 Total consideration $ 148 Fair value of assets and liabilities acquired as of the date of acquisitions: US$ MILLIONS Cash and cash equivalents $ 70 Accounts receivable and other 13 Intangible assets 1,094 Goodwill 44 Accounts payable and other liabilities (99) Non-recourse borrowings (481) Deferred income tax liabilities (152) Net assets acquired before non-controlling interest 489 Non-controlling interest (1) (341) Net assets acquired $ 148 (1) Non-controlling interest represents the consideration paid for the interest not acquired by Brookfield Infrastructure, measured at fair value at the acquisition dates. (b) Acquisition of a Canadian diversified midstream operation On August 20, 2021, Brookfield Infrastructure, alongside institutional partners (collectively, the “IPL consortium”) acquired an effective 41% interest (IPL consortium total of 69%) in IPL for total consideration of approximately $2.8 billion (IPL consortium total of approximately $4.7 billion). The acquisition was funded through cash provided by the partnership of $0.8 billion (IPL consortium total of $1.9 billion), $0.2 billion of BIPC exchangeable LP units, $1.1 billion of BIPC exchangeable shares and $0.5 billion (IPL consortium total of $0.9 billion) of asset level debt raised on closing. In addition, Brookfield Infrastructure had an existing 3% interest in IPL (IPL consortium total - 10%) valued at $0.2 billion prior to the acquisition (IPL consortium total of $0.6 billion). Concurrently, Brookfield Infrastructure entered into a voting agreement with an affiliate of Brookfield, providing Brookfield Infrastructure the right to direct the relevant activities of the entity, thereby providing Brookfield Infrastructure with control. Accordingly, Brookfield Infrastructure consolidated the entity effective August 20, 2021. Acquisition costs of approximately $65 million were recorded as Other income (expense) within the Consolidated Statements of Operating Results. Consideration Transferred: US$ MILLIONS Cash $ 1,268 BIPC exchangeable shares 1,061 BIPC exchangeable LP units 245 Pre-existing interest in business (1) 192 Total consideration $ 2,766 (1) Prior to the acquisition, Brookfield held an interest in the acquiree which was accounted for as a financial asset. Fair value of assets and liabilities acquired as of August 20, 2021: US$ MILLIONS Cash and cash equivalents $ 121 Accounts receivable and other 440 Property, plant and equipment 9,864 Intangible assets 2,570 Goodwill 2,096 Accounts payable and other liabilities (700) Lease liabilities (226) Non-recourse borrowings (6,185) IPL shares held by public shareholders (1) (2,086) Deferred income tax liabilities (1,229) Net assets acquired before non-controlling interest 4,665 Non-controlling interest (2) (1,899) Net assets acquired $ 2,766 (1) IPL shares held by public shareholders represent the 31% interest in IPL not yet acquired by Brookfield as of August 20, 2021. The interest is classified as liability on acquisition due to the mandatory extension of Brookfield’s offer to acquire the remaining interest in IPL. The mandatory extension expired on September 3, 2021 and the remaining $1.6 billion interest was reclassified to non-controlling interest thereafter. (2) Non-controlling interest represents the consideration paid for the interest not acquired by Brookfield Infrastructure, measured at fair value at the acquisition date. The goodwill recorded on acquisition is largely reflective of the potential to obtain long-term contracts for the business’ unutilized capacity and production growth. The goodwill recognized is not deductible for income tax purposes. Subsequent to the initial acquisition, Brookfield Infrastructure, alongside institutional partners, acquired an additional 4% interest (IPL consortium total of 7%) in IPL during the period between August 25, 2021 and September 3, 2021, increasing our partnership’s ownership of the business to approximately 45% (IPL consortium total of 76%), for approximately $315 million (IPL consortium total of $530 million). The acquisition was funded through cash provided by the partnership of approximately $225 million (IPL consortium total of approximately $440 million), $11 million of BIPC exchangeable LP units and $79 million of BIPC exchangeable shares. No gain or loss was recognized on acquisition. On October 28, 2021, Brookfield Infrastructure, alongside institutional partners, acquired an additional 14% interest (IPL consortium total of 24%) in IPL for total consideration of $0.9 billion (IPL consortium of $1.6 billion). The acquisition was funded through cash provided by the partnership of approximately $0.4 billion (IPL consortium total of approximately $1.1 billion) and $0.5 billion of BIPC exchangeable shares and BIPC exchangeable LP units. Subsequent to the acquisition, our partnership’s ownership of the business is 59% (IPL consortium total of 100%). As a result of the carrying value of non-controlling interests exceeding the purchase price, a gain of approximately $30 million was recognized directly in ownership changes and recorded within Other items on the Consolidated Statements of Partnership Capital. For the year ended December 31, 2021, our Canadian diversified midstream operation contributed revenues of $906 million and net income of $59 million. c) Acquisition of additional interest in our Brazilian regulated gas transmission operation On April 30, 2021, Brookfield Infrastructure, alongside institutional partners (the “NTS consortium”), acquired an additional 3% interest (NTS consortium total of 10%) in our Brazilian regulated gas transmission operation, increasing our partnership’s ownership of the business to approximately 31%. Total consideration paid was $87 million (NTS consortium total of $283 million), all of which was funded using asset level debt raised on closing. As a result of the purchase price exceeding the previous carrying value of non-controlling interests, a loss of $32 million was recognized directly in ownership changes and recorded within Other items on the Consolidated Statements of Partnership Capital. d) Individually insignificant business combinations In 2021, Brookfield and its institutional partners (the “acquisition consortiums”) acquired a 26% interest in an Australian port operation for approximately $15 million (acquisition consortium total of approximately $50 million for a 100% interest), a 11% interest in a European residential infrastructure operation for approximately $20 million (acquisition consortium total of approximately $165 million for a 100% interest), a 15% interest in a U.K. residential infrastructure operation for approximately $20 million (acquisition consortium total of approximately $125 million for a 100% interest), a 30% interest in a North American residential infrastructure operation for approximately $25 million (acquisition consortium total of $90 million for a 100% interest), a 29% interest in a North American data center operation for approximately $5 million (acquisition consortium total of approximately $25 million for a 100% interest), and a 9% interest in a North American rail operation for approximately $1 million (acquisition consortium total of approximately $10 million for a 100% interest). The following table summarizes the purchase price allocation of individually insignificant business combinations that were completed in 2021: US$ MILLIONS Cash $ 79 Deferred consideration 3 Contingent consideration 2 Total consideration $ 84 Fair value of assets and liabilities acquired (provisional) (1) : US$ MILLIONS Cash and cash equivalents $ 26 Accounts receivable and other 34 Property, plant and equipment 314 Intangible assets 71 Goodwill 260 Accounts payable and other liabilities (51) Lease liabilities (109) Non-recourse borrowings (32) Deferred income tax liabilities (49) Net assets acquired before non-controlling interest 464 Non-controlling interest (2) (380) Net assets acquired $ 84 (1) The fair values of certain acquired assets and liabilities for these operations have been determined on a provisional basis given the proximity of the acquisitions to the reporting date, pending finalization of the determination of the fair values of the acquired assets and liabilities. Our partnership is in the process of obtaining additional information primarily in order to assess the fair values of property, plant and equipment, intangible assets, deferred income taxes and the resulting impact to goodwill as at the date of the acquisitions. (2) Non-controlling interest represents the interest not acquired by Brookfield Infrastructure, measured at fair value at the acquisition dates.

FAIR VALUE OF FINANCIAL INSTRUM

FAIR VALUE OF FINANCIAL INSTRUMENTS	12 Months Ended

Fair Value Measurement [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair values are determined by reference to quoted bid or ask prices, as appropriate. Where bid and ask prices are unavailable, the closing price of the most recent transaction of that instrument is used. In the absence of an active market, fair values are determined based on prevailing market rates such as bid and ask prices, as appropriate for instruments with similar characteristics and risk profiles or internal or external valuation models, such as option pricing models and discounted cash flow analyses, using observable market inputs. Fair values determined using valuation models require the use of assumptions concerning the amount and timing of estimated future cash flows and discount rates. In determining those assumptions, Brookfield Infrastructure looks primarily to external readily observable market inputs such as interest rate yield curves, currency rates, and price and rate volatilities as applicable. The fair value of interest rate swap contracts which form part of financing arrangements is calculated by way of discounted cash flows using market interest rates and applicable credit spreads. Classification of Financial Instruments Financial instruments classified as fair value through profit or loss are carried at fair value on the Consolidated Statements of Financial Position. Changes in the fair values of financial instruments classified as fair value through profit or loss are recognized in profit or loss. Mark-to-market adjustments on hedging items for those in an effective hedging relationship and changes in the fair value of securities designated as fair value through other comprehensive income are recognized in other comprehensive income.

(3) $20 million of preferred shares issued to subsidiaries of Brookfield. Hedging Activities Brookfield Infrastructure uses derivatives and non-derivative financial instruments to manage or maintain exposures to interest and currency risks. For certain derivatives which are used to manage exposures, Brookfield Infrastructure determines whether hedge accounting can be applied. When hedge accounting can be applied, a hedge relationship can be designated as a fair value hedge, cash flow hedge or a hedge of foreign currency exposure of a net investment in a foreign operation with a functional currency other than the U.S. dollar. To qualify for hedge accounting, the derivative must be designated as a hedge of a specific exposure and the hedging relationship must meet all of the hedge effectiveness requirements in accomplishing the objective of offsetting changes in the fair value or cash flows attributable to the hedged risk both at inception and over the life of the hedge. If it is determined that the hedging relationship does not meet all of the hedge effectiveness requirements, hedge accounting is discontinued prospectively. Cash Flow Hedges Brookfield Infrastructure uses interest rate swaps to hedge the variability in cash flows related to a variable rate asset or liability and highly probable forecasted issuances of debt. The settlement dates coincide with the dates on which the interest is payable on the underlying debt, and the amount accumulated in equity is reclassified to profit or loss over the period that the floating rate interest payments on debt affect profit or loss. For the year ended December 31, 2022, pre-tax net unrealized gains of $547 million (2021: gains of $293 million, 2020: losses of $104 million) were recorded in other comprehensive income for the effective portion of the cash flow hedges. As at December 31, 2022, there was a net derivative asset balance of $645 million relating to derivative contracts designated as cash flow hedges (2021: asset balance of $101 million). Net Investment Hedges Brookfield Infrastructure uses foreign exchange contracts and foreign currency denominated debt instruments to manage its foreign currency exposures arising from net investments in foreign operations having a functional currency other than the U.S. dollar. For the year ended December 31, 2022, gains of $229 million (2021: gains of $2 million, 2020: losses of $12 million) were recorded in other comprehensive income relating to hedges of net investments in foreign operations. Further, Brookfield Infrastructure received $178 million (2021: paid $19 million, 2020: received $83 million) relating to the settlement of foreign exchange contracts in the period. As at December 31, 2022, there was a net unrealized derivative asset balance of $5 million relating to derivative contracts designated as net investment hedges (2021: net unrealized derivative liability balance of $31 million). Fair Value Hierarchical Levels—Financial Instruments Fair value hierarchical levels are directly determined by the amount of subjectivity associated with the valuation inputs of these assets and liabilities, and are as follows: Level 1 — Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 — Inputs other than quoted prices included in Level 1 are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. Fair valued assets and liabilities that are included in this category are primarily certain derivative contracts and other financial assets carried at fair value in an inactive market. Level 3 — Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to determining the estimate. Fair valued assets and liabilities that are included in this category are interest rate swap contracts, derivative contracts, certain equity securities carried at fair value which are not traded in an active market and the non-controlling interest’s share of net assets of limited life funds. The fair value of our partnership’s financial assets and financial liabilities are measured at fair value on a recurring basis. The following table summarizes the valuation techniques and significant inputs for Brookfield Infrastructure’s financial assets and financial liabilities: US$ MILLIONS Fair value hierarchy Dec. 31, 2022 Dec. 31, 2021 Highly liquid securities Level 1 (1) $ 108 $ 179 Foreign currency forward contracts Level 2 (2) Financial asset $ 159 $ 104 Financial liability 37 98 Interest rate swaps & other Level 2 (2) Financial asset $ 1,005 $ 882 Financial liability 233 307 Other contracts Level 3 (3) Financial asset $ 786 $ 6 Financial liability 92 96 (1) Valuation technique: Quoted bid prices in an active market. (2) Valuation technique: Discounted cash flow. Future cash flows are estimated based on observable forward exchange and interest rates at the end of the reporting period, and contract forward rates, discounted at a rate that reflects our credit risk and the credit risk of various counterparties. (3) Valuation technique: Discounted cash flow. Future cash flows primarily driven by assumptions concerning the amount and timing of estimated future cash flows and discount rates. During the year, Brookfield Infrastructure transferred the fair value measurements on financial assets of $460 million to Level 3 of the fair value hierarchy, reflecting a change in valuation technique to a discounted cash flow approach driven by assumptions concerning the amount and timing of estimated future cash flows and discount rates. No other transfers were made between level 1 and 2 or level 2 and 3.

(4) Includes right-of-use assets of $126 million (2021: $118 million) in our utilities segment, $1,014 million (2021: $1,179 million) in our transport segment, $345 million (2021: $389 million) in our midstream segment and $1,973 million (2021: $2,287 million) in our data segment. The partnership’s property, plant, and equipment is measured at fair value on a recurring basis with an effective date of revaluation for all asset classes of December 31, 2022 and 2021. Brookfield Infrastructure determined fair value under the income method or on a depreciated replacement cost basis. Assets under development were revalued where fair value could be reliably measured. The following table summarizes the valuation techniques and significant inputs for the valuation of property, plant and equipment using the income method, categorized by segment. Dec. 31, 2022 Dec. 31, 2021 Segment Valuation Technique (1) Discount Rate Terminal Value Multiple Investment Horizon Valuation Technique (1) Discount Rate Terminal Value Multiple Investment Horizon Utilities Discounted cash flow model 7% to 11% 18x 10 to 20 yrs Discounted cash flow model 7% to 11% 20x 10 to 20 yrs Transport Discounted cash flow model 8% to 14% 9x to 15x 10 yrs Discounted cash flow model 7% to 14% 9x to 15x 10 yrs Midstream Discounted cash flow model 15% 10x 5 to 10 yrs Discounted cash flow model 15% 10x 5 to 10 yrs (1) Certain businesses are valued using the replacement cost method as a result of their underlying operations. Replacement costs are determined with guidance from independent studies and third party evaluators. An increase in the discount rate would lead to a decrease in the fair value of property, plant and equipment. Conversely, an increase to the terminal value multiple would increase the fair value of property, plant and equipment. Our partnership has classified all property, plant and equipment under level 3 of the fair value hierarchy. At December 31, 2022, Brookfield Infrastructure carried out an assessment of the fair value of its utilities property, plant and equipment, resulting in a gain from revaluation of $175 million (2021: $134 million) which was recognized in revaluation surplus in the Consolidated Statements of Comprehensive Income. The key driver behind the revaluation gain recorded was growth in underlying cash flows at our U.K. regulated distribution business, as a result of additional connections and increased tariffs. At December 31, 2022, Brookfield Infrastructure carried out an assessment of the fair value of its transport property, plant and equipment. A gain from revaluation of $75 million (2021: $48 million) was recognized in revaluation surplus in the Consolidated Statements of Comprehensive Income. Stronger volumes and higher charges and tariffs were the main contributors to the gain. At December 31, 2022, Brookfield Infrastructure carried out an assessment of the fair value of its midstream property, plant and equipment. A gain from revaluation of $118 million (2021: $70 million) was recognized in revaluation surplus in the Consolidated Statements of Comprehensive Income. Underlying valuation assumptions in the midstream segment remain relatively consistent with the prior year with the current year’s gain attributable to favorable market conditions and organic growth. At December 31, 2022, Brookfield Infrastructure carried out an assessment of the fair value of its data property, plant and equipment, which are measured using replacement cost approach. No revaluation gains were recognized in revaluation surplus in the Consolidated Statements of Comprehensive Income (2021: $nil). The following table summarizes the carrying amount of property, plant and equipment that would have been recognized had assets been carried under the cost model, inclusive of purchase price allocations.

(2) Refer to Note 6, Assets and Liabilities Held for Sale, for further details. (3) Other intangibles are primarily comprised of customer contracts at our Australian port operation, Western Canadian natural gas gathering and processing operation, U.S. data center operation, Colombian natural gas transmission operation, natural gas operation in India and contracted order book at our U.K. regulated distribution operation. The intangible assets at our Brazilian regulated transmission operation relate to concession arrangements with the local energy regulator, Agência Nacional do Petróleo, Gás Natural e Biocombustíveis (“ANP”). Total capacity is fully contracted under long-term “ship-or-pay” gas transportation agreements (“GTA”) and therefore, the business is exposed to no volume or price risk. Each GTA takes into account a return on regulatory asset base (“RAB”), and the tariffs are calculated on an inflation adjusted regulatory weighted average cost of capital (“WACC”) fixed for the life of GTAs. On April 8, 2021, new legislation was passed in Brazil which provides our Brazilian regulated gas transmission operation the right to operate the gas pipelines perpetually. The intangible assets are amortized on a straight-line basis over the estimated useful life of the underlying infrastructure. The intangible assets at our Canadian diversified midstream operation relate to long-term take-or-pay and fee-for-service contractual arrangements which are not materially impacted by volume or commodity price fluctuations. These customer relationships and shipping agreements are with investment grade counterparties. Revenues are recognized over time as transportation services are fulfilled. The intangible assets will be amortized on a straight-line basis over the estimated useful life. The intangible assets at Brookfield Infrastructure’s North American rail operations mainly relate to customer relationships, operating network agreements and track access rights. The business provides critical first and last mile rail services which connect large Class I railroad operators to end customers. Our North American freight revenue is diversified across numerous commodities and the business largely performed in line with expectations. Customer relationships and operating network agreements as well as trackage rights, which are long-term leases, are not expected to be negatively impacted in the long term. The intangible assets at our North American residential infrastructure operation are comprised of contractual customer relationships, customer contracts, proprietary technology and brands. The contractual customer relationships and customer contracts represent ongoing economic benefits from leasing customers and annuity-based management agreements. Proprietary technology is recognized for the development of new metering technology, which allows the business to generate revenue through its sub-metering business. Brands represent the intrinsic value customers place on the operation’s various brand names. The business generates revenues under long-term contracts with a diversified customer base across North America and is exposed to minimum volume risk. The terms and conditions of the Peruvian toll roads concession, including tariffs that can be charged to the users and the duties to be performed by the operator, are regulated by the Municipalidad Metropolitana de Lima (“MML”) and its municipal arm, Fondo Metropolitano de Inversiones. The service concession provides the operator the right to charge a tariff to vehicles which use the road network over the life of the concession in exchange for the design, construction, improvement, maintenance and operation of the road network. Tariffs are adjusted annually for the Lima Metropolitana Consumer Price Index. The concession arrangement has an expiration date of 2043 at which point the underlying concession assets will be returned to the MML. The intangible asset at Brookfield Infrastructure’s Indian telecom tower operation relates primarily to the customer contract with Reliance Jio, India’s largest cellular network operator. Reliance Jio is an anchor tenant of our tower operation under a 30-year Master Service Agreement. The terms and conditions of the Simhapuri Expressway (“SEL”), Rayalseema Expressway (“REPL”) and Mumbai Nasik (“MNEL”) Indian toll road concessions, including tariffs that can be charged to the users and the duties to be performed by the operator, are regulated by the National Highways Authority of India (“NHAI”). The Service Concession Agreements provides the operators the right to charge a tariff to vehicles which use the road over the term of the concession in exchange for operating the road, including preserving the road based on a defined maintenance schedule. Tariffs are revised annually for the Indian Wholesale Price Index. The Concession Arrangements have expiration dates of 2041, 2040 and 2026, respectively, for SEL, REPL and MNEL, at which point the underlying concessions assets will be returned to the NHAI. The intangible asset at Brookfield Infrastructure’s U.K telecom tower operation primarily relates to customer contracts and related relationships. The contractual customer contracts and customer relationships represent ongoing economic benefits from leasing space on the existing portfolio of towers and distributed antenna systems. Intangible assets are amortized straight-line over the average remaining contractual period plus a reasonable expectation of long term renewals. The intangible asset at Brookfield Infrastructure’s U.K. port operation relates to a conservancy right. As a right in perpetuity issued by the Statutory Harbour Authority in the U.K., the conservancy right is classified as having an indefinite life, and is subject to an annual impairment review. The carrying value as at December 31, 2022, of Brookfield Infrastructure’s indefinite lived intangibles is $866 million (2021: $899 million).

(2) See Note 5, Disposition of Businesses, for additional information. (3) See Note 6, Assets and Liabilities Classified as Held for Sale, for additional information. Goodwill is evaluated for impairment annually or more often if events or circumstances indicate there may be impairment. Impairment is determined by assessing if the carrying value of cash generating units or a group of cash generating units, including the allocated goodwill, exceeds its recoverable amount determined as the greater of the estimated fair value less costs of disposal or the value in use. During 2022, the carrying amount of each cash generating unit was determined to not exceed its recoverable amount. Goodwill is allocated to the following cash generating units or group of cash generating units: US$ MILLIONS 2022 2021 North American rail operations $ 2,094 $ 2,105 Canadian diversified midstream operation 1,984 2,125 North American residential energy infrastructure operation 1,463 1,356 Western Canadian natural gas gathering and processing operation 710 762 U.S. data center operation 503 503 Brazilian regulated transmission operation 488 456 Colombian natural gas distribution operation 367 433 U.K. telecom tower operation 332 341 Other 848 898 Total $ 8,789 $ 8,979 The recoverable amount of goodwill has been determined using a discounted cash flow model whereby the fair value measurement is classified under level 3 on the fair value hierarchy. For businesses with the most significant goodwill as separately listed in the table above, the key inputs in determining the fair value of each cash generating unit under the discounted cash flow model are the utilization of discount rates ranging from 11% to 14%, terminal value multiples of 8x to 20x and discrete cash flow periods from 6 to 19 years.

The $2.1 billion is available on a revolving basis for the full term of the facility. All amounts outstanding under this facility will be repayable on June 29, 2027. All obligations of Brookfield Infrastructure under the facility are guaranteed by our partnership. Loans under this facility accrue interest at a floating rate based on SOFR plus 1.2%. Brookfield Infrastructure is required to pay an unused commitment fee under the facility of 13 basis points per annum. As at December 31, 2022, there were $96 million (2021: $nil) draws outstanding on the credit facility and $12 million of letters of credit were issued (2021: $12 million).

(2) Maturity and annual rate associated with our commercial paper program represents a weighted average of all outstanding obligations as of December 31, 2022. Brookfield Infrastructure has entered into a $1 billion revolving credit facility with Brookfield to provide additional liquidity for general corporate purposes and capital expenditures, if required. The revolving credit facility automatically renews for eight consecutive one-year terms, which would result in the facility ultimately maturing in February 2027. Brookfield has the option to terminate the agreement prior to April 14 each year by providing Brookfield Infrastructure with a written notice. Loans under this facility accrued interest on LIBOR plus 1.8% and no commitment fees were incurred for any undrawn balance. As of December 31, 2022, there were no (2021: $nil) borrowings outstanding. On November 14, 2022, Brookfield Infrastructure Finance ULC issued C$700 million of medium-term notes in two tranches: C$450 million maturing on November 14, 2027 with a coupon of 5.616% per annum and C$250 million maturing on February 14, 2033 with a coupon of 5.980% per annum, and $2 million of debt issuance costs were incurred. On April 25, 2022, Brookfield Infrastructure Finance ULC issued C$600 million of medium-term notes in two tranches: C$400 million maturing on April 25, 2034 with a coupon of 5.439% per annum and C$200 million maturing on April 25, 2052 with a coupon of 5.789% per annum, and $3 million of debt issuance costs were incurred. On May 24, 2021, Brookfield Infrastructure Finance ULC issued $250 million of subordinated notes maturing May 24, 2081, with a coupon of 5.0% and $6 million of debt issuance costs were incurred.

Proceeds from the commercial paper issuances are supplemented by our corporate credit facilities. As of December 31, 2022, there were $464 million of borrowings outstanding (2021: $431 million). The increase in corporate borrowings of $947 million during the year ended December 31, 2022 is primarily attributable to the issuance of approximately $960 million of medium-term notes and net draws on our corporate credit facility of $96 million. These increases were partially offset by the impact of foreign exchange.

PARTNERSHIP CAPITAL

PARTNERSHIP CAPITAL	12 Months Ended
	Dec. 31, 2022
Equity [abstract]
PARTNERSHIP CAPITAL	PARTNERSHIP CAPITAL As at December 31, 2022, our partnership’s capital structure was comprised of three classes of partnership units: limited partnership units, preferred units and general partnership units. Limited partnership units entitle the holder to their proportionate share of distributions. Preferred units entitle the holder to cumulative preferential cash distributions in accordance with their terms. General partnership units entitle the holder the right to govern the financial and operating policies of our partnership. The Holding LP’s capital structure is composed of four classes of partnership units: special general partner units, Holding LP Class A preferred units, managing general partner units and redeemable partnership units held by Brookfield. On June 10, 2022, Brookfield Infrastructure completed a three-for-two split of our units, BIPC exchangeable shares, Exchange LP Units, and BIPC exchangeable LP units, by way of a subdivision whereby unitholders/shareholders received an additional one-half of a unit/share for each unit/share held. The Managing General Partner Units, Special General Partner Units and Redeemable Partnership Units of the Holding LP were concurrently split. Brookfield Infrastructure’s preferred units were not affected by the split. All historical unit and share counts, as well as per unit/share disclosures have been adjusted to effect for the change in units as a result of the splits. In its capacity as the holder of the Special General Partner Units of the Holding LP, the special general partner is entitled to incentive distribution rights which are based on the amount by which quarterly distributions on the Holding LP’s units (other than Holding LP Class A Preferred Units) exceed specified target levels. To the extent distributions on the Holding LP’s units (other than Holding LP Class A Preferred Units) exceed $0.1218 per quarter, the incentive distribution rights entitle the special general partner to 15% of incremental distributions above this threshold. To the extent that distributions on the Holding LP’s units (other than Holding LP Class A Preferred Units) exceed $0.1320 per unit, the incentive distribution rights entitle the special general partner to 25% of incremental distributions above this threshold. During the year, the Holding LP paid incentive distributions of $240 million (2021: $206 million, 2020: $183 million). Prior to the split on June 10, 2022, the above thresholds of $0.1218 and $0.1320 were $0.1827 and $0.1980, respectively. Prior to the special distribution on March 30, 2020, the above thresholds were $0.2030 and $0.22, respectively. The Holding LP has issued 193.6 million Redeemable Partnership Units to Brookfield, which may, at the request of the holder, require the Holding LP to redeem the Redeemable Partnership Units for cash in an amount equal to the market value of our units. This right is subject to our partnership’s right of first refusal which entitles it, at its sole discretion, to elect to acquire any Redeemable Partnership Units so presented to the Holding LP in exchange for one of our partnership’s units (subject to certain customary adjustments). Both the units issued by our partnership and the Redeemable Partnership Units issued by the Holding LP have the same economic attributes in all respects, except for the redemption right described above. The Redeemable Partnership Units participate in earnings and distributions on a per Redeemable Partnership Unit basis equivalent to the per unit participation of the units of our partnership. Our partnership reflects the Redeemable Partnership Units issued to Brookfield by the Holding LP as non-controlling interest—Redeemable Partnership Units held by Brookfield.

In total, $556 million of gross proceeds were raised through the issuance and $23 million in equity issuance costs were incurred. Concurrently, Brookfield Infrastructure issued approximately 10.7 million Redeemable Partnership Units at the public offering price, net of commissions, to Brookfield for additional proceeds of $400 million. As a result of the issuances during 2021, inclusive of equity raised as part of the IPL acquisition, equity was reallocated between limited partners, the general partner, non-controlling interests - Redeemable Partnership Units held by Brookfield, non-controlling interests - Exchange LP units, non-controlling interests - BIPC exchangeable LP units, and non-controlling interests - BIPC exchangeable shares to reflect the difference between the ratio in which the unit/shareholders participated in the issuance and their original economic interest in the partnership. The resulting impacts were recognized as ownership changes within the Consolidated Statements of Partnership Capital. Amounts in accumulated other comprehensive income (loss) were also ratably allocated. During the year ended December 31, 2022, Brookfield Infrastructure did not repurchase units (2021: nil, 2020: less than 0.2 million for less than $0.1 million) and did not incur any commission costs (2021: $nil, 2020: less than $1 million). Our partnership has implemented a distribution reinvestment plan (the “Plan”) that allows eligible holders of our units 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 New York Stock Exchange for the five trading days immediately preceding the relevant distribution date. During the year ended December 31, 2022, our partnership issued 0.3 million units for proceeds of $13 million (2021: 0.4 million units for proceeds of $12 million, 2020: 0.3 million units for proceeds of $9 million). The weighted average number of Special General Partner Units outstanding for the year ended December 31, 2022 was 2.4 million (2021: 2.4 million, 2020: 2.4 million). The weighted average number of limited partnership units outstanding for the year ended December 31, 2022 was 458.1 million (2021: 445.1 million, 2020: 442.1 million). Net income per limited partnership unit was $0.14 for the year ended December 31, 2022 (2021: $1.16, 2020: $0.23). Net income per limited partnership unit is calculated as the total net income attributable to limited partnership units, less preferred partnership distributions, divided by the average number of limited partnership units outstanding during the year ended December 31, 2022.

The distribution resulted in no cash proceeds to the partnership. The BIPC exchangeable shares provide holders with economic terms that are substantially equivalent to those of our units and are exchangeable, on a one-for-one basis, for our units. Given the exchangeable feature, the BIPC exchangeable shares are presented as a component of non-controlling interests. Refer to Note 1, Organization and Description of the Business, for further details. During the year ended December 31, 2022, BIPC exchangeable shareholders exchanged less than 0.1 million (2021: less than 0.1 million) BIPC exchangeable shares for less than $1 million of our units (2021: $1 million).

Related Party [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS In the normal course of operations, Brookfield Infrastructure entered into the transactions below with related parties. The immediate parent of Brookfield Infrastructure is our partnership. The ultimate parent of Brookfield Infrastructure is Brookfield. Other related parties of Brookfield Infrastructure represent its subsidiary and operating entities. Throughout the year, the General Partner, in its capacity as our partnership’s general partner, incurs director fees, a portion of which are charged at cost to our partnership in accordance with our limited partnership agreement. Director fees of $1 million were incurred during the year ended December 31, 2022 (2021: $1 million, 2020: $1 million). Since inception, Brookfield Infrastructure has had a management agreement (the “Master Services Agreement”) with certain service providers (the “Service Providers”), which are 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 Service Providers equal to 0.3125% per quarter (1.25% annually) of the market value of our partnership. The Base Management Fee was $421 million for the year ended December 31, 2022 (2021: $394 million, 2020: $302 million). As of December 31, 2022, $91 million was outstanding as payable to the Service Providers (December 31, 2021: $108 million). For purposes of calculating the Base Management Fee, the market value of our partnership is equal to the aggregate value of all the outstanding units of our partnership (assuming full conversion of Brookfield’s Redeemable Partnership Units in the Holding LP into units of our partnership), preferred units and securities of the other Service Recipients (as defined in Brookfield Infrastructure’s Master Services Agreement) that are not held by Brookfield Infrastructure, plus all outstanding third party debt with recourse to a Service Recipient, less all cash held by such entities. As of December 31, 2022, Brookfield Infrastructure had a loan payable of $25 million to subsidiaries of Brookfield (December 31, 2021: $26 million). The loan is payable in full prior to the end of 2024 with an interest rate of 1.7%. Brookfield Infrastructure, from time to time, will place deposits with, or receive deposits from, Brookfield. As at December 31, 2022, our net deposit from Brookfield was $nil (December 31, 2021: $nil) and Brookfield Infrastructure incurred interest expense of less than $4 million for the year ended December 31, 2022 (2021: $3 million, 2020: $1 million). Deposits bear interest at market rates. Brookfield Infrastructure has entered into a $1 billion revolving credit facility with Brookfield to provide additional liquidity for general corporate purposes and capital expenditures, if required. As of December 31, 2022, there were no (December 31, 2021: $nil) borrowings outstanding. As at December 31, 2022, Brookfield Infrastructure had approximately $160 million of borrowings outstanding to subsidiaries and associates of Brookfield (December 31, 2021: $51 million) and approximately $0.7 billion of net payables to subsidiaries of Brookfield (December 31, 2021: $0.6 billion). Brookfield Infrastructure’s subsidiaries provide heating, cooling, connection, port marine and natural gas services on market terms in the normal course of operations to subsidiaries and associates of Brookfield. For the year ended December 31, 2022, revenues of $8 million were generated (2021: $10 million, 2020: $12 million). Brookfield Infrastructure’s subsidiaries purchase power, lease office space and obtain construction, consulting and engineering services in the normal course of operations on market terms from subsidiaries and associates of Brookfield. For the year ended December 31, 2022, expenses of $144 million were incurred (2021: $37 million, 2020: $2 million). In addition, subsidiaries of Brookfield Infrastructure reported lease assets and liabilities of $12 million (December 31, 2021: $12 million) with a subsidiary of Brookfield. During the fourth quarter of 2022, our partnership sold a portfolio of investments, which included partial interests in consolidated subsidiaries and financial assets, with an approximate fair value of $310 million to an affiliate of Brookfield in exchange for securities of equal value. The portfolio of investments represented seed assets in a new product offering that Brookfield will be marketing and selling to third party investors which at that time will allow our partnership, subject to certain conditions, monetize the securities to generate liquidity. The securities are recorded as financial assets on the Consolidated Statement of Financial Position. The reduction in partial interests in consolidated subsidiaries is reflected as an increase in non-controlling interest of others in operating subsidiaries on the Consolidated Statement of Financial Position. Subsequent to year end, on February 28, 2023, our partnership exercised its redemption option associated with the securities and redeemed a portion of its units with a fair value of $230 million.

DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTSBrookfield Infrastructure’s activities expose it to a variety of financial risks, including market risk (i.e. currency risk, interest rate risk, commodity risk and other price risk), credit risk and liquidity risk. Brookfield Infrastructure and its subsidiaries selectively use derivative financial instruments principally to manage these risks. The aggregate notional amount of Brookfield Infrastructure’s derivative positions at December 31, 2022 and 2021 were as follows: US$ MILLIONS Note 2022 2021 Foreign exchange contracts (a) $ 2,912 $ 4,383 Interest rates swaps and other (b) 9,543 10,095 Commodity contracts 115 424 $ 12,570 $ 14,902 The following table presents the change in fair values of Brookfield Infrastructure’s derivative positions during the years ended December 31, 2022 and 2021: US$ MILLIONS Unrealized Gains Unrealized Losses Net Change During 2022 Net Change During 2021 Foreign exchange derivatives $ 130 $ (11) $ 119 $ 100 Interest rate and other derivatives 643 (131) 512 298 Commodity derivatives 52 (16) 36 (43) $ 825 $ (158) $ 667 $ 355 (a) Foreign Exchange Brookfield Infrastructure held the following foreign exchange contracts with notional amounts at December 31, 2022 and 2021.

(b) Interest Rates At December 31, 2022, Brookfield Infrastructure held interest rate and cross currency interest rate swap contracts having an aggregate notional amount of $9,543 million (2021: $10,095 million). Our partnership has an aggregate notional amount of $4,064 million floating interest rate derivatives that are benchmarked against the LIBOR, $738 million floating interest rates derivatives that are benchmarked against the bank bill swap rate, $1,911 million floating interest rates derivatives that are benchmarked against the CDOR and $734 million floating interest rates derivatives that are benchmarked against the SOFR. It is currently expected that the Secured Overnight Financing Rate will replace US$ LIBOR prior to June 30, 2023. As at December 31, 2022, this reform has resulted in no material economic impact on our partnership’s floating rate borrowings. Other Information Regarding Derivative Financial Instruments The following table presents the notional amounts underlying Brookfield Infrastructure’s derivative instruments by term to maturity as at December 31, 2022 and the comparative notional amounts at December 31, 2021, for both derivatives that are classified as fair value through profit or loss and derivatives that qualify for hedge accounting: 2022 2021 US$ MILLIONS < 1 year 1 to 5 years > 5 years Total Notional Total Notional Fair value through profit or loss Foreign exchange derivatives $ 1,186 $ 821 $ — $ 2,007 $ 2,103 Interest rate derivatives Interest rate swaps, cross currency interest rate swaps and other 81 639 — 720 686 Commodity contracts 106 9 — 115 424 $ 1,373 $ 1,469 $ — $ 2,842 $ 3,213 Elected for hedge accounting Foreign exchange derivatives $ 114 $ 318 $ 473 $ 905 $ 2,280 Interest rate derivatives Interest rate and cross currency interest rate swaps 1,712 5,939 1,172 8,823 9,409 $ 1,826 $ 6,257 $ 1,645 $ 9,728 $ 11,689 The following table classifies derivatives elected for hedge accounting during the years ended December 31, 2022 and 2021 as either cash flow hedges or net investment hedges. Changes in the fair value of the effective portion of the hedges are recorded in either other comprehensive income or net income, depending on the hedge classification, whereas changes in the fair value of the ineffective portion of the hedge are recorded in net income: 2022 2021 AS AT AND FOR THE YEARS ENDED (MILLIONS) Notional Effective Ineffective Notional Effective Ineffective Cash flow hedges $ 9,308 $ 529 $ 1 $ 9,981 $ 288 $ 28 Net investment hedges 420 235 — 1,708 62 (14) $ 9,728 $ 764 $ 1 $ 11,689 $ 350 $ 14 Our partnership settles the difference between the contracted fixed and floating rates of its interest rate swaps on a net basis. All interest rate swap contracts exchanging floating rate interest amounts for fixed rate interest amounts are designated as cash flow hedges in order to reduce our partnership’s cash flow exposure resulting from variable interest rates on borrowings. The interest rate swaps and the interest payments on the borrowings occur simultaneously and the amount accumulated in equity is reclassified to profit or loss over the period that the floating rate interest payments on borrowings affect profit or loss.

FINANCIAL RISK MANAGEMENT

FINANCIAL RISK MANAGEMENT	12 Months Ended

Financial Instruments [Abstract]
FINANCIAL RISK MANAGEMENT	FINANCIAL RISK MANAGEMENT Brookfield Infrastructure is exposed to the following risks as a result of holding financial instruments: capital risk; liquidity risk; market risk (i.e. interest rate risk and foreign currency risk); and credit risk. The following is a description of these risks and how they are managed: (a) Liquidity Risk Management 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 2021. Our non-recourse borrowings have increased due to recently completed acquisitions while maintaining our consolidated net debt to capitalization ratio consistent with the prior year. The capital structure of Brookfield Infrastructure consists of debt, offset by cash and cash equivalents, and partnership capital comprised of issued capital and accumulated gains. US$ MILLIONS 2022 2021 Corporate borrowings $ 3,666 $ 2,719 Non-recourse borrowings 26,567 26,534 Subsidiary and corporate borrowings 30,233 29,253 Preferred shares 20 20 Cash and cash equivalents (1) (2,117) (1,924) Consolidated net debt 28,136 27,349 Total partnership capital 25,554 26,391 Total capital and consolidated net debt $ 53,690 $ 53,740 Consolidated net debt to capitalization ratio 52 % 51 % (1) Includes current marketable securities. The Board, along with senior management of the Service Providers, 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 borrows 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 acquisitions or outsized organic growth initiatives. The equity portion of capital expenditures and normal levels of acquisition of activity will be self-funded through operating cash flows retained in the business and proceeds from the sale of mature, de-risked businesses. However, Brookfield Infrastructure may also issue equity opportunistically to enhance its liquidity to pursue investment activity. Brookfield Infrastructure maintains active 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, Brookfield Infrastructure will evaluate a variety of capital sources including proceeds from selling mature assets, equity and debt financing. Our 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 Note 20, Borrowings , Brookfield Infrastructure has various loan facilities in place. In certain cases, the facilities have financial covenants which are generally in the form of interest coverage 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 requirements. 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 its distribution of 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 corporate liquidity as at December 31 was as follows: US$ MILLIONS (1) 2022 2021 Corporate cash and financial assets $ 891 $ 683 Availability under committed credit facilities (2) 3,100 3,475 Commercial paper (464) (431) Draws on credit facility (96) — Commitments under credit facility (12) (12) Corporate liquidity $ 3,419 $ 3,715 (1) Liquidity managed by Brookfield Infrastructure L.P. and affiliated corporate entities.

We anticipate being able to refinance or obtain waivers from our financial institutions and accordingly presented the debt in the contractually obligated year of maturity. (2) Interest expense on Corporate borrowings include undiscounted interest obligations on $250 million of subordinated notes maturing May 24, 2081, with a coupon of 5.0% (b) Market Risk Market risk is defined for these purposes as the risk that the fair value or future cash flows of a financial instrument held by Brookfield Infrastructure will fluctuate because of the change in market prices. Market risk includes the risk of changes in interest rates, foreign currency exchange rates and equity prices. 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 Brookfield Infrastructure’s Treasury Policy. Brookfield Infrastructure does not enter into, or trade financial instruments, including derivative financial instruments, for speculative purposes. The Treasury Policy provides written principles on the use of financial derivatives. With respect to its treasury policy, the Service Providers performs the monitoring, review and approval role and report to the Board on a regular basis. Financial instruments held by Brookfield Infrastructure that are subject to market risk include other financial assets, borrowings, derivative instruments, such as interest rate and foreign currency contracts, and marketable securities. Our partnership is exposed to equity price risks arising from marketable securities. As at December 31, 2022, the balance of the portfolio was $1,007 million (2021: $588 million), a 10% change in the value of the portfolio would impact our equity by $101 million and result in an impact on our comprehensive income of $101 million. Interest Rate Risk Management Brookfield Infrastructure’s primary objectives with respect to interest rate risk management are to ensure that: • Brookfield Infrastructure is not exposed to interest rate movements that could adversely impact its ability to meet financial obligations; • Earnings and distributions are not adversely affected; • Volatility of debt servicing costs is managed within acceptable parameters; and • All borrowing covenants under various borrowing facilities, including interest coverage ratios, are complied with. To achieve these objectives, in general terms, Brookfield Infrastructure’s funding mix comprises both fixed and floating rate debt. Fixed rate debt is achieved either through fixed rate debt funding or through the use of financial derivative instruments. In addition, where possible, interest rate risk is minimized by matching the terms of interest rate swap contracts in regulated businesses to the term of the rate period, thus providing natural hedges. The sensitivity analyses below reflect Brookfield Infrastructure’s exposure to interest rates for both derivative and non-derivative instruments at the reporting date, assuming that a 50 basis point increase or decrease in rates takes place at the beginning of the financial year and is held constant throughout the reporting period. The sensitivity analyses assume a 50 basis point change to reflect the current methodology employed by Brookfield Infrastructure in assessing interest rate risk. Such parallel shift in the yield curve by 50 basis points would have had the following impact, assuming all other variables were held constant: 2022 US$ MILLIONS 50 bp decrease 50 bp increase Net income (loss) to the partnership (1) $ 8 $ (8) Other comprehensive income (loss) to the partnership (1) 2 (2) (1) Includes net income and other comprehensive income (loss) attributable to limited partners, the general partner, non-controlling interests - Redeemable Partnership Units held by Brookfield, non-controlling interests - Exchangeable units and non-controlling interests - BIPC exchangeable shares. Foreign Currency Risk Management 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 leverages any natural hedges that may exist within its operations, including local inflation indexation; • Brookfield Infrastructure utilizes local currency debt financing to the extent possible; and • Brookfield Infrastructure may utilize derivative contracts to the extent that natural hedges are insufficient.

From a treasury perspective, counterparty credit risk is managed through the establishment of authorized counterparty credit limits which are designed to ensure that Brookfield Infrastructure only deals with creditworthy counterparties and that counterparty concentration is addressed and the risk of loss is mitigated. Credit limits are sufficiently low to restrict Brookfield Infrastructure 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 Brookfield Infrastructure’s scale of activity and allow it to manage its treasury business competitively. Brookfield Infrastructure 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. Exposure to credit risk is limited to the carrying amount of the assets on the Consolidated Statements of Financial Position.

Disclosure of Capital Management [Abstract]
CAPITAL MANAGEMENT	CAPITAL MANAGEMENT Our partnership’s approach to capital management is focused on maximizing returns to unitholders and ensuring capital is deployed in a manner consistent with achieving our investment return objectives. Invested Capital, which tracks the amount of capital that has been contributed to our partnership, is a measure we utilize to assess returns on capital deployed, relative to targeted returns. Investment decisions are based on, amongst other measures and factors, targeted returns on Invested Capital of 12% to 15% annually over the long-term. We measure return on Invested Capital as Adjusted Funds from Operations (“AFFO”), less estimated returns of capital on operations that are not perpetual in nature, divided by the weighted average Invested Capital for the period. We define AFFO as FFO less capital expenditures required to maintain the current performance of our operations (maintenance capital expenditures). We define Invested Capital as partnership capital removing the impact of the following items: non-controlling interest - in operating subsidiaries, retained earnings or deficit, accumulated other comprehensive income and ownership changes. US$ MILLIONS 2022 2021 Partnership Capital $ 25,554 $ 26,391 Remove impact of the following items since inception: Non-controlling interest - in operating subsidiaries (15,320) (15,658) Deficit 3,422 2,520 Accumulated other comprehensive income (817) (543) Ownership changes (558) (515) Invested Capital $ 12,281 $ 12,195 The following table presents the change in Invested Capital during year ended December 31, 2022 and 2021: For the year ended December 31, US$ MILLIONS 2022 2021 Opening balance $ 12,195 $ 9,213 Net (redemption) issuance of preferred units (220) 8 Issuance of perpetual subordinated notes 293 — Issuance of limited partnership and redeemable partnership units, net of redemptions 13 945 Issuance of BIPC exchangeable shares — 1,770 Issuance of BIPC exchangeable LP Units — 259 Ending balance $ 12,281 $ 12,195 Weighted Average Invested Capital (1) $ 12,270 $ 10,076 (1) For the purposes of calculating Weighted Average Invested Capital for the year ended December 31, 2022, redemption of preferred units and issuance of perpetual subordinated notes of $220 million and $293 million, respectively, were assumed to have been completed concurrently in January of 2022.

Cash Flow Statement [Abstract]
SUPPLEMENTAL CASH FLOW INFORMATION	SUPPLEMENTAL CASH FLOW INFORMATION For the year ended US$ MILLIONS 2022 2021 2020 Interest paid $ 1,638 $ 1,074 $ 985 Income taxes paid $ 364 $ 262 $ 172 Amounts paid and received for interest were reflected as operating cash flows in the Consolidated 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 Statements of Cash Flows depending upon the nature of the underlying transaction. Details of “Changes in non-cash working capital, net” on the Consolidated Statements of Cash Flows are as follows: For the year ended US$ MILLIONS 2022 2021 2020 Accounts receivable $ (445) $ (190) $ 284 Prepayments (117) (11) (415) Accounts payable and other (342) (323) (89) Changes in non-cash working capital, net (1) $ (904) $ (524) $ (220) (1) During the year ended December 31, 2022, changes in non-cash working capital include a $0.3 billion (2021: $0.3 billion, 2020: $0.3 billion) reduction to cash related to the impact of finance lease receivables signed at our North American residential energy infrastructure operation. The operation presents an outflow for the cost of inventory within the operating cash flows, and given the business has been securitized since 2019, the corresponding cash outflows are more than offset by increases in non-recourse borrowings under financing activities on the Consolidated Statements of Cash Flows.

SUBSEQUENT EVENTS

Disclosure of events after reporting period [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS On January 4, 2023, Brookfield Infrastructure, alongside institutional partners (the “HomeServe consortium”), completed the acquisition of HomeServe PLC (“HomeServe”), a residential infrastructure business operating in North America and Europe, and acquired all the issued and outstanding shares of HomeServe for £12 per share or approximately $1.2 billion (HomeServe consortium total of approximately $4.9 billion). The partnership has an effective 26% and 25% interest in HomeServe’s North American and European businesses, respectively. Due to the recent closing of the acquisition, the complete valuation and initial purchase price accounting for the business combination is not available as at the date of release of these financial statements. As a result, the partnership has not provided amounts recognized as at the acquisition date for certain major classes of assets acquired and liabilities assumed.

SIGNIFICANT ACCOUNTING POLICI_2

SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2022
Corporate Information And Statement Of IFRS Compliance [Abstract]
Statement of Compliance	Statement of Compliance These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”). The consolidated financial statements were authorized for issue by the Board of Directors on March 17, 2023.
Basis of Preparation	Basis of PreparationThe consolidated financial statements are prepared on a going concern basis.
Subsidiaries	Subsidiaries These consolidated financial statements include the accounts of our partnership and subsidiaries over which our partnership has control. Subsidiaries are consolidated from the date of acquisition, being the date on which our partnership obtains control, and continue to be consolidated until the date when control is lost. Our partnership (investor) controls an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Together, our partnership and its subsidiaries are referred to as “Brookfield Infrastructure” in these financial statements. 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 in addition to changes in ownership interests. Total comprehensive income is attributed to non-controlling interests, even if this results in the non-controlling interests having a deficit balance. Holding LP has issued Redeemable Partnership Units held by Brookfield, which may, at the request of the holder, require the Holding LP to redeem the Redeemable Partnership Units for cash consideration equal to the market price of our partnership’s units. This right is subject to our partnership’s right of first refusal which entitles it, at its sole discretion, to elect to acquire any Redeemable Partnership Unit so presented to Holding LP in exchange for one of our partnership’s units subject to certain customary adjustments. All intercompany balances, transactions, revenues and expenses are eliminated in full.
Associates and Joint Ventures	Associates and Joint VenturesAssociates and joint ventures are entities over which our partnership has significant influence or joint control. Significant influence is the power to participate in the financial and operating policy decisions of the investee but does not constitute control. Our partnership accounts for investments over which it has significant influence using the equity method, and are recorded as Investments in associates and joint ventures on the Consolidated Statements of Financial Position. Interests in investments accounted for using the equity method are initially recorded at cost. If the cost of the associate is lower than the proportionate share of the investment’s underlying fair value, our partnership records a gain on the difference between the cost and the underlying fair values of the identifiable net assets of the associate. If the cost of the associate is greater than our partnership’s proportionate share of the underlying fair value, goodwill and other adjustments arising from the purchase price allocation relating to the associate is included in the carrying amount of the investment. Subsequent to initial recognition, the carrying value of our partnership’s interest in an investee is adjusted for our partnership’s share of comprehensive income or loss and distributions from the investee. Profits or losses resulting from transactions with an associate are recognized in the consolidated financial statements based on the interests of unrelated investors in the associate.
Foreign Currency Translation	Foreign Currency Translation The U.S. dollar is the functional and presentation currency of Brookfield Infrastructure. Each of Brookfield Infrastructure’s subsidiaries, associates and jointly controlled entities determines its own functional currency and items included in the financial statements of each subsidiary and associate 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 other comprehensive income. On disposal of a foreign operation resulting in the loss of control, the component of other comprehensive income due to accumulated foreign currency translation relating to that foreign operation is reclassified to net income. 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. On partial disposal of a foreign operation in which control is retained, the proportionate share of the component of other comprehensive income or loss relating to that foreign operation is reclassified to non-controlling interests in that foreign operation. Foreign currency denominated monetary assets and liabilities are translated using the rate of exchange prevailing at the reporting date and 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 net income. Gains and losses on transactions which hedge these items are also included in net income or loss. Foreign currency denominated non-monetary assets and liabilities, measured at historic cost, are translated at the rate of exchange at the transaction date.
Business Combinations	Business CombinationsBusiness acquisitions in which control is acquired 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 transferred by the acquirer, liabilities incurred or assumed, and equity instruments issued by Brookfield Infrastructure in exchange for control of the acquiree. Acquisition related costs are recognized in the Consolidated Statements of Operating Results as incurred and included in other 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 the acquisition where they qualify as measurement period adjustments. All other subsequent changes in the fair value of contingent consideration classified as liabilities will be recognized in the Consolidated Statements of Operating Results, whereas changes in the fair values 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 the Consolidated Statements of Operating Results. Amounts arising from interests in the acquiree prior to the acquisition date that have previously been recognized in other comprehensive income are reclassified to the Consolidated Statements of Operating Results, 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 to the acquisition date. 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 profit or loss as a bargain purchase gain. 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 (“IAS 37”) and the amount initially recognized less cumulative amount of income recognized in accordance with IFRS 15, Revenue from Contracts with Customers .
Cash and Cash Equivalents	Cash and Cash EquivalentsCash and cash equivalents include cash on hand and short-term, highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value.
Accounts Receivable	Accounts ReceivableTrade receivables are recognized initially at their transaction price and subsequently measured at amortized cost using the effective interest method, less any allowance for expected credit losses. (g) Inventory Inventory is valued at the lower of cost and net realizable value. Cost is determined using the weighted average costing method and includes direct purchase costs as well as costs of production, storage, and transportation of natural gas, natural gas liquids and other hydrocarbons. Net realizable value represents the estimated selling price in the ordinary course of business less estimated costs of completion and selling costs. If applicable, an increase in net realizable value representing a reversal of a previous inventory write-down is recognized as an increase in inventory.
Property, Plant and Equipment	Property, Plant and Equipment Brookfield Infrastructure uses the revaluation method of accounting for all classes of property, plant and equipment. Property, plant and equipment is initially measured at cost and subsequently carried at its 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 at least an annual basis, and on a sufficient 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 other comprehensive income or loss and accumulated in equity within the revaluation surplus reserve, unless the increase reverses a previously recognized impairment recorded through net income, in which case that portion of the increase is recognized in net income. 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 net income. Revaluation gains are included in other comprehensive income, but are not subsequently recycled into profit or loss. 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 the Consolidated Statements of Operating Results. However, any balance accumulated in revaluation surplus is subsequently recorded in retained earnings when an asset is derecognized and not transferred to profit or loss. Depreciation of an asset commences when it is available for use. Property, plant and equipment are depreciated on a straight-line or declining-balance basis over the estimated useful lives of each component of the assets as follows: Buildings Up to 75 years Transmission stations, towers and related fixtures Up to 40 years Leasehold improvements Up to 50 years Plant and equipment Up to 40 years Network systems Up to 65 years Track Up to 40 years District energy systems Up to 50 years Pipelines Up to 20 years Gas storage assets Up to 50 years
Investment Properties	Investment Properties Brookfield Infrastructure uses the fair value method to account for assets classified as investment property. An asset 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 profit or loss. Fair values are primarily determined by valuation of the lease term and freehold reversion. An income capitalization approach is used by applying a yield to the rental income of the capitalization rate that is reflective of the characteristics, location and market of each property. Fair value is estimated by management of our partnership with due consideration given to observable market inputs, where available.
Asset Impairment	Asset ImpairmentAt each reporting date, Brookfield Infrastructure assesses whether for assets, other than those measured at fair value with changes in values recorded in profit or loss, there is any indication that such assets are impaired. This assessment includes a review of internal and external factors which includes, but is not limited to, changes in the technological, political, economic or legal environment in which the entity operates in, structural changes in the industry, changes in the level of demand, physical damage and obsolescence due to technological changes. An impairment is recognized if the recoverable amount, determined as the higher of the estimated fair value less costs of disposal or the discounted future cash flows generated from use and eventual disposal from an asset or cash generating unit is less than its carrying value. The projections of future cash flows take into account the relevant operating plans and management’s best estimate of the most probable set of conditions anticipated to prevail. Where an impairment loss subsequently reverses, the carrying amount of the asset or cash generating unit is increased to the lesser of the revised estimate of recoverable amount and the carrying amount that would have been recorded had no impairment loss been recognized previously.
Intangible Assets	Intangible Assets Intangible assets acquired in a business combination and recognized separately from goodwill are initially recognized at their fair value at the acquisition date. Brookfield Infrastructure’s intangible assets are comprised primarily of conservancy rights, service concession arrangements, customer order backlogs, track access rights, operating network agreements and customer contracts and relationships. Subsequent to initial recognition, intangible assets acquired in a business combination are reported at cost less accumulated amortization unless indefinite-lived 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 under IFRIC 12, Service Concession Arrangements . Concession arrangements were acquired as part of the acquisition of the Brazilian regulated gas transmission operation, Brazilian electricity transmission operation and Indian and Peruvian toll roads and were initially recognized at their fair values. The intangible assets at the Brazilian regulated gas transmission operation and Brazilian electricity transmission operation relate to concession contracts. For our Brazilian regulated gas transmission operation, the concession arrangement provides the business with the right to operate the asset perpetually. As a result, the asset is amortized over its estimated useful life. For our Brazilian electricity transmission operation, the intangible asset is amortized on a straight-line basis over the life of the contractual arrangement. The intangible assets at the Indian and Peruvian toll roads relate to the right to operate a road and charge users a specified tariff for a contractual length of time and is amortized over the life of the contractual arrangement with an average of 15 and 21 years remaining, respectively. 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 profit or loss when the asset is derecognized.
Goodwill	Goodwill Goodwill represents the excess of the price paid for the acquisition of an entity over the fair value of the net tangible and intangible assets and liabilities acquired. Goodwill is allocated to the cash generating unit or units to which it relates. Brookfield Infrastructure identifies cash generating units as identifiable groups of assets that are largely independent of the cash inflows from other assets or groups of assets. Goodwill is evaluated for impairment annually or more often if events or circumstances indicate there may be impairment. Impairment is determined for goodwill by assessing if the carrying value of a cash generating unit, including the allocated goodwill, exceeds its recoverable amount determined as the greater of the estimated fair value less costs of disposal or the value in use. Impairment losses recognized in respect of a cash generating unit are first allocated to the carrying value of goodwill and any excess is allocated to the carrying amount of assets in the cash generating unit. Any goodwill impairment is charged to profit or loss in the period in which the impairment is identified. Impairment losses on goodwill are not subsequently reversed. In the year of a business acquisition, the recoverability of the acquired goodwill is assessed by revisiting the assumptions of the related underwriting model. On disposal of a subsidiary, the attributable amount of goodwill is included in the determination of the gain or loss on disposal of the operation.
Revenue Recognition	Revenue Recognition Our partnership recognizes revenue when it transfers control of a product or service to a customer. Revenue is measured based on the consideration specified in a contract with a customer and excludes amounts collected on behalf of third parties. 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. Utilities Revenue from utilities infrastructure is derived from the transmission of energy and natural gas, and from our commercial and residential distribution operations. Distribution and transmission revenue each contain a single performance obligation that is recognized over time. The connection revenue relating to Brookfield Infrastructure’s U.K. regulated distribution operation contains a distinct performance obligation that is recognized over the period that the connection is constructed, based on an input method of progress recognition on the basis that this methodology is most reflective of the underlying transfer of control. Performance obligations relating to commercial and residential distribution operations are satisfied over time as the services are rendered or upon commencement of a finance lease agreement. The payment terms for all of our businesses in the utilities segment require payment upon completion, except for connections income whereby payment is typically collected up-front prior to the completion of any services. Transport Revenue from transport infrastructure consists primarily of freight, toll road operations, transportation services revenue, and from our Australian export terminal. These services consist of a single performance obligation and revenue is recognized over time when services are rendered, based primarily on usage or volume during the period. Terminal infrastructure revenue contains both a capacity charge and a handling charge associated with operating the terminal. The terminal infrastructure service contracts contain a performance obligation recognized over time pertaining to capacity for the period the services are provided and for handling services based on tons of coal shipped through the terminal when service is provided. The payment terms for all of our businesses in the transport segment require payment upon completion of the underlying transportation service. Midstream Revenue from midstream infrastructure consists primarily of midstream and storage services. Natural gas midstream services revenue consists of a single performance obligation and is recognized over time as services are rendered, based primarily on volume throughput or contracted capacity. Revenue associated with the sale of raw materials consists of a single performance obligation and is recognized upon delivery. Gas storage revenues contain both a capacity charge and a variable charge, however the associated services are highly interdependent and represent a single performance obligation that is satisfied over time as the services are provided. The payment terms for all of our businesses in the midstream segment require payment upon completion of the underlying service within a given period.
Financial Instruments and Hedge Accounting	Financial Instruments and Hedge Accounting (i) Financial Instrument Classification Our partnership classifies cash and cash equivalents and accounts receivable and other as amortized cost. Additionally, our partnership maintains a portfolio of marketable securities comprised of liquid equity and debt securities. The marketable securities are classified either as fair value through other comprehensive income (“FVTOCI”) or fair value through profit or loss (“FVTPL”). Derivative assets are classified as FVTPL, except for derivatives in certain hedging relationships. Other financial assets are classified as either amortized cost or FVTOCI. Financial assets classified as FVTPL or FVTOCI are subsequently measured at fair value at each reporting date. For financial assets classified as FVTPL, the change in fair value is recorded through profit or loss. For financial assets classified as FVTOCI, the change in fair value is recorded in other comprehensive income. The cumulative gains or losses related to FVTOCI equity instruments are not reclassified to profit or loss on disposal, whereas the cumulative gains or losses on all other FVTOCI assets are reclassified to profit or loss on disposal. For financial instruments at amortized cost or debt instruments at FVTOCI, the partnership assesses if there have been significant increases in credit risk since initial recognition to determine whether lifetime or 12-month expected credit losses should be recognized. Any related loss allowances are recorded through profit or loss. Borrowings, accounts payable and other, and preferred shares are classified as amortized cost, except for derivatives embedded in related financial instruments. Embedded derivatives and any other derivative liabilities are classified as FVTPL and are subsequently measured at fair value, except for derivatives in certain hedging relationships. Other financial liabilities are classified as either FVTPL or amortized cost. (ii) Hedge Accounting Brookfield Infrastructure selectively utilizes derivative financial instruments primarily to manage financial risks, including interest rate and foreign exchange risks. Derivative financial instruments are recorded at fair value. Hedge accounting is applied when the derivative is designated as a hedge of a specific exposure and that the hedging relationship meets all of the hedge effectiveness requirements. 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 other comprehensive income by the application of hedge accounting is recognized in profit or loss over the remaining term of the original hedging relationship as amounts related to the hedged item are recognized in profit or loss. The assets or liabilities relating to unrealized mark-to-market gains and losses on derivative financial instruments are recorded in financial assets and financial liabilities, respectively. 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 equity 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 profit or loss or as a component of equity as applicable.
Income Taxes	Income Taxes Income tax expense represents the sum of the tax accrued in the period and deferred income tax. (i) Current income 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 or substantively enacted at the reporting date. Current income tax relating to items recognized directly in partnership capital and other comprehensive income are also recognized directly in partnership capital and other comprehensive income, respectively. (ii) Deferred income tax 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 consolidated 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 income tax assets and liabilities are not recognized if the temporary difference arises from goodwill or from the initial recognition of other assets and liabilities in a transaction that affects neither the taxable income nor the accounting income, other than in a business combination. 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 income 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 income 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. 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 income tax liabilities and assets reflect 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 income 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 within a single taxable entity or Brookfield Infrastructure intends to settle its current tax assets and liabilities on a net basis in the case where there exist different taxable entities in the same taxation authority and when there is a legally enforceable right to set off current tax assets against current tax liabilities.
Assets Held for Sale	Assets Held for Sale 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 subject to limited exceptions. 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 Consolidated Statements of Financial Position and are classified as current. The liabilities of a disposal group classified as held for sale are presented separately from other liabilities in the Consolidated Statements of Financial Position. Once classified as held for sale, property, plant and equipment and intangible assets are not depreciated or amortized, respectively.
Provisions	Provisions Provisions are recognized when Brookfield Infrastructure has a present obligation, either 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.
Recently adopted accounting standards	Future accounting policies The following are accounting policies issued that the partnership expects to adopt in the future: Amendments to IAS 1 – Classification of Liabilities as Current or Non-current The amendments to IAS 1 affect only the presentation of liabilities as current or non-current in the consolidated balance sheets and not the amount or timing of recognition of any asset, liability, income or expenses, or the information disclosed about those items. The amendments clarify that the classification of liabilities as current or non-current is based on rights that are in existence at the end of the reporting period, specify that classification is unaffected by expectations about whether the partnership will exercise its right to defer settlement of a liability, explain that rights are in existence if covenants with which an entity is required to comply on or before the end of the reporting period, and introduce a definition of ‘settlement’ to make clear that settlement refers to the transfer to the counterparty of cash, equity instruments, other assets or services. The amendments are applied retrospectively for annual periods beginning on or after January 1, 2024, with early application permitted. The partnership is in the process of determining the impact of the amendments on its consolidated financial statements.
Critical Accounting Judgments and Key Sources of Estimation Uncertainty	Significant Accounting Judgments and Key Sources of Estimation Uncertainty The preparation of financial statements requires management to make significant judgments, 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. Significant judgments and estimates made by management and utilized in the normal course of preparing Brookfield Infrastructure’s consolidated financial statements are outlined below. (i) Common control transactions IFRS 3 (2008) Business Combinations 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 in the IFRS framework and pronouncements of other standard-setting bodies. Brookfield Infrastructure’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 Consolidated Statements of Financial Position, Consolidated Statements of Operating Results, Consolidated Statements of Comprehensive Income and Statements of Cash Flows 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. (ii) Financial instruments Brookfield Infrastructure’s accounting policies relating to derivative financial instruments are described in Note 3(n), Financial Instruments and Hedge Accounting. The significant judgments inherent in these policies relate to applying the criteria to the assessment of the effectiveness of hedging relationships. Estimates and assumptions used in determining the fair value of financial instruments are equity and commodity prices; future interest rates; the credit worthiness of the company relative to its counterparties; the credit risk of our partnership and counterparty; estimated future cash flows; and discount rates. (iii) Revaluation of property, plant and equipment Property, plant and equipment is revalued on a regular basis. The significant estimates and assumptions underlying the valuation of property, plant and equipment are set out in Note 14, Property, Plant and Equipment. (iv) Fair values in business combinations 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 discounted at an appropriate rate to reflect the risk inherent in the acquired assets and liabilities (refer to Note 7, Acquisition of Businesses 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. (v) Assets held for sale Brookfield Infrastructure applies judgment to determine whether an asset or disposal group is available for immediate sale in its present condition and that its sale is highly probable and therefore should be classified as held for sale at the balance sheet date. Conditions that support a highly probable sale include the following: an appropriate level of management is committed to a plan to sell the asset or disposal group, an active program to locate a buyer is initiated, the asset is being actively marketed for sale at a price reasonable in relation to its fair value, the sale is highly probably within 12 months of classification as held for sale, and actions required to complete the plan indicate that it is unlikely that plan will be significantly changed or withdrawn. (vi) Impairment of goodwill, intangibles with indefinite lives and investment in associates and joint ventures The impairment assessment of goodwill and intangible assets with indefinite lives requires estimation of the value-in-use or fair value less costs of disposal of the cash-generating units or groups of cash generating units to which goodwill or the intangible asset has been allocated. Brookfield Infrastructure uses the following critical assumptions and estimates: the circumstances that gave rise to the goodwill, timing and amount of future cash flows expected from the cash-generating units; discount rates; terminal capitalization rates; terminal valuation dates and useful lives. The impairment assessment of investments in associates and joint ventures requires estimation of the recoverable amount of the asset. Other estimates utilized in the preparation of our partnership’s financial statements are: depreciation and amortization rates and useful lives; recoverable amount of goodwill and intangible assets; ability to utilize tax losses and other tax measurements.

The operation presents an outflow for the cost of inventory within the operating cash flows, and given the business has been securitized since 2019, the corresponding cash outflows are offset by increases in non-recourse borrowings under financing activities on the Consolidated Statements of Cash Flows.

Disclosure of sensitivity analysis for interest rate and foreign exchange risk	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. The sensitivity analyses assume a 50 basis point change to reflect the current methodology employed by Brookfield Infrastructure in assessing interest rate risk. Such parallel shift in the yield curve by 50 basis points would have had the following impact, assuming all other variables were held constant: 2022 US$ MILLIONS 50 bp decrease 50 bp increase Net income (loss) to the partnership (1) $ 8 $ (8) Other comprehensive income (loss) to the partnership (1) 2 (2) (1) Includes net income and other comprehensive income (loss) attributable to limited partners, the general partner, non-controlling interests - Redeemable Partnership Units held by Brookfield, non-controlling interests - Exchangeable units and non-controlling interests - BIPC exchangeable shares. 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: • Outstanding foreign currency denominated monetary items (excluding foreign exchange derivative contracts) are adjusted at period end for a 10% change in foreign currency rates from the rate at which they are translated; • Foreign currency derivative contracts are measured as the change in fair value of the derivative as a result of a 10% change in the spot currency rate; and • The impact on net income results from performing a sensitivity of a 10% change in foreign exchange rates applied to the profit or loss contribution from foreign operations (after considering the impact of foreign exchange derivative contracts).

Disclosure of changes in non-cash working capital	Details of “Changes in non-cash working capital, net” on the Consolidated Statements of Cash Flows are as follows: For the year ended US$ MILLIONS 2022 2021 2020 Accounts receivable $ (445) $ (190) $ 284 Prepayments (117) (11) (415) Accounts payable and other (342) (323) (89) Changes in non-cash working capital, net (1) $ (904) $ (524) $ (220) (1) During the year ended December 31, 2022, changes in non-cash working capital include a $0.3 billion (2021: $0.3 billion, 2020: $0.3 billion) reduction to cash related to the impact of finance lease receivables signed at our North American residential energy infrastructure operation. The operation presents an outflow for the cost of inventory within the operating cash flows, and given the business has been securitized since 2019, the corresponding cash outflows are more than offset by increases in non-recourse borrowings under financing activities on the Consolidated Statements of Cash Flows.
