2. SUMMARY OF ACCOUNTING POLICIES
a) 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 interim condensed and consolidated financial statements of our partnership.

ii)Basic and diluted income per unit:
The special distribution resulted in the issuance of approximately 46.3 million exchangeable shares.
b) Statement of Compliance
These interim condensed and consolidated financial statements of our partnership and its subsidiaries (together “Brookfield Infrastructure”) have been prepared in accordance with International Accounting Standard 34, Interim Financial Reporting, (“IAS 34”) as issued by the International Accounting Standards Board (“IASB”) and using the accounting policies Brookfield Infrastructure applied in its consolidated financial statements as of and for the year-ended December 31, 2020. The accounting policies that our partnership applied in its annual consolidated financial statements as of and for the year-ended December 31, 2020 are disclosed in Note 3 of such financial statements, with which reference should be made in reading these interim condensed and consolidated financial statements.
These interim condensed and consolidated financial statements were authorized for issuance by the Board of Directors of our partnership on August 9, 2021.
c) Critical Accounting Judgments and Key Sources of Estimation Uncertainty
In preparing our consolidated financial statements, we make judgments in applying our accounting policies. The areas of policy judgment are consistent with those reported in our consolidated financial statements as of and for the year ended December 31, 2020. As disclosed in our 2020 annual consolidated financial statements, our partnership uses critical assumptions and estimates to determine the fair value of our property, plant and equipment and 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 an intangible asset has been allocated.
In March 2020, the World Health Organization declared a global pandemic related to COVID-19. To date, there has been significant volatility in commodity and foreign exchange markets as well as restrictions on the conduct of business in many jurisdictions and the global movement of people and certain goods. In light of the economic environment, our partnership has assessed the impact of the economic shutdowns on our asset valuations. In making these assessments, we reviewed business risks, cash flow assumptions, and discount rates for the impacts of government imposed shutdowns. We have applied certain assumptions as to the pace of economic recovery and continue to monitor operating results against them. As a provider of essential services, substantially all of our businesses have remained in operation while we continue to safeguard the health of our employees. In addition, the majority of our businesses are subject to regulated cash flows or long-term take-or-pay contracts with minimal volume risk. Based on our partnership’s assessment, no impairments to our asset values were required as at June 30, 2021.
d) Recently adopted accounting standards
Brookfield Infrastructure applied, for the first time, certain new standards applicable to our partnership that became effective January 1, 2021. The impact of these amendments on our partnership’s accounting policies are as follows:
Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16: Disclosures
Our partnership adopted Interest Rate Benchmark Reform - Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16 (“Phase II Amendments”), effective January 1, 2021. The Phase II Amendments provide additional guidance to address issues that will arise during the transition of benchmark interest rates. The Phase II Amendments primarily relate to the modification of financial assets, financial liabilities and lease liabilities where the basis for determining the contractual cash flows changes as a result of IBOR reform, allowing for prospective application of the applicable benchmark interest rate and to the application of hedge accounting, providing an exception such that changes in the formal designation and documentation of hedge accounting relationships that are needed to reflect the changes required by IBOR reform do not result in the discontinuation of hedge accounting or the designation of new hedging relationships. The adoption did not have a significant impact on our partnership’s financial reporting.

3. 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. Key measures used by the Chief Operating Decision Maker (“CODM”) in assessing performance and in making resource allocation decisions are Funds from Operations (“FFO”) and adjusted earnings before interest, tax, depreciation and amortization (“Adjusted EBITDA”), which enable the determination of return on the equity deployed. FFO is calculated as net income excluding the impact of depreciation and amortization, deferred income taxes, breakage and transaction costs, and non-cash valuation gains or losses. Adjusted EBITDA is calculated as net income excluding the impact of depreciation and amortization, interest expense, current and deferred income taxes, breakage and transaction costs, and non-cash valuation gains or losses.
During the fourth quarter of 2020, our partnership conducted a comprehensive review of our operating segments. To better align with how our CODM reviews and evaluates our operations, our district energy and Indian natural gas operations were reallocated to our utilities segment and our Australian export terminal was reallocated to our transport segment. Our energy segment was renamed to midstream and our data infrastructure segment was renamed to data. Comparative figures have been adjusted retrospectively to reflect the impact of the reallocation.

5. DISPOSITION OF BUSINESSES
a) Disposition of Canadian district energy operation
On June 7, 2021, Brookfield Infrastructure, alongside institutional partners (collectively the “Enwave Canada consortium”) completed the sale of its 25% interest in our Canadian district energy operation. The sale resulted in net proceeds of approximately $450 million (Enwave Canada consortium total of approximately $1,770 million). Our partnership recognized a gain of approximately $295 million (Enwave Canada consortium total of approximately $1,170 million) in Other income (expense) on the Consolidated Statements of Operating Results. The partnership’s share of accumulated revaluation surplus of $124 million was reclassified from accumulated other comprehensive income directly to retained earnings and recorded within Other items on the Consolidated Statements of Partnership Capital. The partnership’s share of net gains relating to previous foreign exchange movements and hedges of $9 million were reclassified from accumulated other comprehensive income to Other income (expense) on the Consolidated Statements of Operating Results.
b) Disposition of our U.K. regulated distribution business’s portfolio of smart meters
On May 12, 2021, our U.K. regulated distribution business sold its smart meters business for gross consideration of approximately $820 million. After the repayment of debt and working capital requirements at the business, our partnership received net proceeds of approximately $340 million. The business recognized a gain of approximately $195 million in Other income (expense) on the Consolidated Statements of Operating Results, of which approximately $155 million is attributable to our partnership.

6. ACQUISITION OF BUSINESSES
Acquisitions Completed in 2021
a) 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.
b) Individually insignificant business combinations
The following table summarizes the purchase price allocation of individually insignificant business combinations that were completed
in 2021:

US$ MILLIONS |
Cash | $ | 51 |
Contingent consideration | 2 |

Net assets acquired | $ | 96 |

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, 2021, the revenue and net income of Brookfield Infrastructure would have been approximately $5.4 billion and $1.7 billion, respectively, for the six-month period ended June 30, 2021.
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 2020
a) Acquisition of a telecom tower operation in India
On August 31, 2020, Brookfield Infrastructure, alongside institutional partners (the “Summit consortium”), acquired an effective 17% interest in Summit Digitel Infrastructure Private Limited, an Indian telecom tower operation (“Summit’) from Reliance Industries Limited (“RIL”) for $584 million (Summit consortium total of approximately $3.4 billion). 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 31, 2020. Acquisition costs of approximately $15 million were recorded in Other income (expense) within the Consolidated Statements of Operating Results.

US$ MILLIONS |
Accounts receivable and other | $ | 408 |
Property, plant and equipment | 6,900 |
Intangible assets | 830 |
Goodwill | 153 |
Accounts payable and other liabilities | (417) |
Non-recourse borrowings | (2,356) |

1.The fair values of certain acquired assets and liabilities for this operation have been determined on a provisional basis given the proximity of the acquisition 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 initial measurement of right-of-use assets and liabilities as at the date of acquisition.
2.Revisions to the purchase price allocation resulted in adjustments to the preliminary fair values, including intangible assets, property, plant and equipment and deferred income tax liabilities. The offsetting adjustment to goodwill resulted in an increase of approximately $125 million.
3.Non-controlling interest represents the consideration paid for the interest not acquired by Brookfield Infrastructure, measured at fair value at the acquisition date, and includes capital provided by non-controlling interest in the form of shareholder loan to the operating business.
The goodwill recorded on acquisition is largely reflective of the potential to obtain long-term contracts for the business’ unutilized capacity of the telecom towers. The goodwill recognized is not deductible for income tax purposes.
b) Partial acquisition of interest in our Colombian natural gas transmission operation
On July 15, 2020, Brookfield Infrastructure, alongside institutional partners (the “Vanti consortium”), completed a take private tender offer resulting in the acquisition of an additional 20% interest (Brookfield Infrastructure’s share - approximately 6%) in our Colombian natural gas transmission operation, increasing our ownership of the business to approximately 21%. Total consideration paid was approximately $45 million (Vanti consortium total of $150 million), of which approximately $25 million (Vanti consortium total of approximately $90 million) was funded through equity and the remainder with 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 $10 million was recognized directly in ownership changes and recorded within Other items on the Consolidated Statements of Partnership Capital.
7. 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.

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 three and six-month periods ended June 30, 2021, losses of $19 million and gains of $160 million, respectively (2020: losses of $16 million and $265 million) were recorded in other comprehensive income for the effective portion of the cash flow hedges. As of June 30, 2021, there was a net derivative asset balance of $34 million relating to derivative contracts designated as cash flow hedges (December 31, 2020: liability balance of $150 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 three and six-month periods ended June 30, 2021, losses of $47 million and $41 million, respectively (2020: losses of $4 million and gains of $130 million) were recorded in other comprehensive income relating to the hedges of net investments in foreign operations. Further, for the three and six-month periods ended June 30, 2021, Brookfield Infrastructure paid $18 million and $17 million, respectively (2020: received $1 million and $83 million) relating to the settlement of foreign exchange contracts in the period. As of June 30, 2021, there was a net unrealized derivative liability balance of $90 million relating to derivative contracts designated as net investment hedges (December 31, 2020: net unrealized derivative liability balance of $49 million).
Q2 2021 INTERIM REPORT 19

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 |  | June 30, 2021 |  | December 31, 2020
Marketable securities | Level 1(1) |  | $ | 687 |  |  | $ | 526 |
Foreign currency forward contracts | Level 2(2) |  |  |  |
Financial asset |  |  | $ | 115 |  |  | $ | 115 |
Financial liability |  |  | 185 |  |  | 251 |
Interest rate swaps & other | Level 2(2) |  |  |  |
Financial asset |  |  | $ | 461 |  |  | $ | 438 |
Financial liability |  |  | 364 |  |  | 561 |
Other contracts | Level 3(3) |  |  |  |
Financial asset |  |  | $ | 6 |  |  | $ | 6 |
Financial liability |  |  | 92 |  |  | 119 |

1.Valuation technique: Quoted bid prices in an active market.
2.Valuation technique: Discounted cash flow. Future cash flows are estimated based on forward exchange and interest rates (from 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.
Assets and liabilities measured at fair value on a recurring basis include $1,269 million (2020: $1,085 million) of financial assets and $641 million (2020: $931 million) of financial liabilities which are measured at fair value using valuation inputs based on management’s best estimates. During the three-month period ended June 30, 2021, no transfers were made between level 1 and 2 or level 2 and 3.

Q2 2021 INTERIM REPORT 21

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, 2020. Brookfield Infrastructure determined fair value under the income method or on a depreciated replacement cost basis. The partnership’s right-of-use assets recorded as property, plant, and equipment are measured using the cost model. Assets under development are revalued where fair value could be reliably measured.
Due to continuous changes in the macroeconomic environment and the interruption to global supply chains, our partnership reviewed the significant inputs to the valuation of our property, plant, and equipment. Based on our analysis, no impairments to our property, plant and equipment were required as at June 30, 2021.

2.Refer to Note 6, Acquisition of Businesses, 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.
Due to continuous changes in the macroeconomic environment and the interruption to global supply chains as a result of the global pandemic, our partnership performed an evaluation of potential impairment indicators on each of our intangible assets as of June 30, 2021. Based on the analysis performed, our intangible assets remain largely unaffected, with no impairment required. Our intangible assets represent long-term critical infrastructure supported by regulated or highly contracted revenues which help protect value over the long term.
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 will be amortized on a straight-line basis over the estimated useful life of the underlying infrastructure.
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.
22 BROOKFIELD INFRASTRUCTURE PARTNERS L.P.

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.

Brookfield Infrastructure has entered into a $500 million 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 four consecutive one-year terms, which would result in the facility ultimately maturing on February 8, 2023. Brookfield has the option to terminate the agreement prior to February 8 each year by providing Brookfield Infrastructure with 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 June 30, 2021, there were $nil (2020: $nil) borrowings outstanding.
On May 24, 2021, Brookfield Infrastructure Finance ULC issued $250 million of subordinated notes maturing May 24, 2081, with a coupon of 5.0%.
On February 24, 2021, Brookfield Infrastructure established a U.S. commercial paper program under which a subsidiary of our partnership may issue unsecured commercial paper notes up to a maximum aggregate amount outstanding at any time of $500 million. Proceeds from the commercial paper issuances are supplemented by our corporate credit facilities. As of June 30, 2021, there were $496 million of borrowing outstanding (2020: $nil).
On September 1, 2020, Brookfield Infrastructure Finance ULC issued C$500 million of medium-term notes maturing September 1, 2032 with a coupon of 2.9% per annum. On October 6, 2020, the proceeds were used to early redeem C$450 million of medium-term notes maturing March 11, 2022.
On April 14, 2020, the partnership secured an incremental $1.0 billion syndicated revolving credit facility. The facility was secured to fund new investment opportunities that may arise while other sources of capital, including asset sales, are delayed. The facility matures on April 14, 2022 and all amounts not previously repaid will be due on such date. All obligations under the facility are guaranteed by our partnership and its subsidiary, BIPC Holdings Inc. Loans under this facility accrue interest at LIBOR plus 1.2% with an annual unused commitment fee of 13 basis points. As of June 30, 2021, the balance remains undrawn (2020: $nil).
On April 7, 2020, Brookfield Infrastructure Finance ULC, a wholly owned subsidiary of Brookfield Infrastructure, issued C$400 million of medium-term notes. C$200 million of the medium-term notes mature September 11, 2028 and have a coupon rate of 4.2% per annum. These notes were issued at a premium with an effective interest rate of 4.1% per annum. The remaining C$200 million medium term notes mature on October 9, 2029 and have a coupon rate of 3.4% per annum. These notes were issued at a discount with an effective interest rate of 4.1%.
The decrease in corporate borrowings during the six-month period ended June 30, 2021 is attributable to net repayments on the revolving credit facility of $1.1 billion, partially offset by the issuance of $250 million subordinated notes, net proceeds of $496 million from our commercial paper program, and the impact of a stronger Canadian dollar relative to the U.S. dollar.

b) Non-Recourse Borrowings

| As of
US$ MILLIONS | June 30, 2021 |  | December 31, 2020
Current | $ | 1,332 |  |  | $ | 1,551 |
Non-current | 18,667 |  |  | 18,469 |
Total | $ | 19,999 |  |  | $ | 20,020 |

Non-recourse borrowings have remained relatively consistent as compared to December 31, 2020. The impact from recent dispositions and $0.5 billion of non-recourse borrowings reclassified as held for sale was offset by $1.1 billion of additional net borrowings primarily associated with our recent acquisitions and growth initiatives.
12. 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 life, divided by the weighted average Invested Capital for the period.
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.

| As of
US$ MILLIONS | June 30, 2021 |  | December 31, 2020
Partnership Capital | $ | 21,451 |  |  | $ | 21,673 |

(the “Holding LP”), Brookfield Infrastructure Holdings (Canada) Inc., Brookfield Infrastructure US Holdings I Corporation, BIP Bermuda Holdings I Limited (collectively, the “BIP Guarantors”), BIPC Holdings Inc. (“BIPC Holdings”), Computershare Trust Company of Canada and Computershare Trust Company, N.A., as supplemented and amended from time to time (the “U.S. Indenture”) provides for the issuance of one or more series of unsecured notes of Brookfield Infrastructure Finance ULC.
On May 24, 2021, Brookfield Infrastructure Finance ULC issued $250 million of subordinated unsecured notes under the U.S. Indenture maturing May 24, 2081 in the United States with a coupon of 5.0% (the “subordinated notes”).
The subordinated notes are fully and unconditionally guaranteed, on a subordinated basis, as to payment of principal, premium (if any) and interest and certain other amounts by the BIP Guarantors and BIPC Holdings. The subordinated notes, including accrued and unpaid interest thereon, will be exchanged automatically, without the consent or action of the holders thereof, into units of a newly-issued series of Class A preferred limited partnership units of the partnership, being class A preferred limited partnership units, Series 15, upon the occurrence of an Automatic Exchange Event (as defined in the U.S. Indenture).
On September 1, 2020, the Debt Issuers issued C$500 million of medium-term notes under the Indenture maturing September 1, 2032 in the Canadian bond market with a coupon of 2.9%, which was swapped into U.S. dollars on a matched maturity basis at an all-in rate of 3.9%. On October 6, 2020, the proceeds were used to early redeem C$450 million of medium-term notes maturing March 11, 2022.

On October 7, 2019, the Debt Issuers issued C$500 million of medium-term notes under the Indenture maturing October 9, 2029 in the Canadian bond market with a coupon of 3.4%. Our partnership swapped C$92 million of the total issuance to U.S. dollars on a matched maturity basis at an all-in rate of 3.5% and the remaining principal balance of the issuance was subsequently hedged using foreign exchange contracts. On November 6, 2019, the proceeds were used to early redeem C$375 million of medium-term notes maturing October 30, 2020.
These medium-term notes are fully and unconditionally guaranteed by the BIP Guarantors and BIPC Holdings.
The BIP Guarantors will also fully and unconditionally guarantee the payment obligations of Brookfield Infrastructure Preferred Equity Inc.

A base shelf prospectus of BIP Investment Corporation (“BIPIC”) dated as of December 11, 2020 provides for the issuance of one or more series of senior preferred shares of BIPIC. The BIP Guarantors and BIPC Holdings will fully and unconditionally guarantee the payment obligations of BIPIC in respect of any senior preferred shares issued by BIPIC under the prospectus.
Each of the Fincos and BIPIC are subsidiaries of our partnership. In the tables below, information relating to the Fincos has been combined. The Fincos have not guaranteed the obligations of BIPIC, nor has BIPIC guaranteed the obligations of the Fincos.
On February 5, 2019, BIPIC issued 4 million Series 1 Senior Preferred Shares at C$25 per share with a quarterly fixed dividend at a rate of 5.85% annually for the initial period ending March 31, 2024. In total, C$100 million or $75 million of gross proceeds were raised, $2 million in underwriting costs were incurred and less than $1 million in issuance costs were incurred. The preferred shares are retractable at the option of the holders and are therefore classified as liabilities.
BIPC Holdings has also fully and unconditionally guaranteed the payment obligations of the partnership in respect of certain of the partnership’s currently outstanding cumulative Class A preferred limited partnership units and may guarantee the payment obligations of the partnership in respect of additional cumulative Class A preferred limited partnership units issued to the public, if and when issued.

Our partnership continues to monitor the credit risk of our counterparties in light of the current economic environment.

15. PARTNERSHIP CAPITAL
As at June 30, 2021, 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 to 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.

In June 2010, we implemented a distribution reinvestment plan (the “Plan”) that allows eligible holders of our partnership to purchase additional units by reinvesting their cash distributions. Under the Plan, units are acquired at a price per unit calculated by reference to the volume weighted average of the trading price for our units on the New York Stock Exchange for the five trading days immediately preceding the relevant distribution date. During the six-month period ending June 30, 2021, our partnership issued 0.1 million units for proceeds of $6 million (2020: less than 0.2 million units for proceeds of $5 million).

18. 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 less than $1 million were incurred during the three and six-month periods ended June 30, 2021 (2020: less than $1 million for the three and six-month periods).
Since inception, Brookfield Infrastructure has had a management agreement (the “Master Services Agreement”) with certain service providers (the “Service Provider”), 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 Provider equal to 0.3125% per quarter (1.25% annually) of the market value of our partnership. The Base Management Fee was $93 million and $185 million respectively, for the three and six-month periods ended June 30, 2021 (2020: $69 million and $128 million). As of June 30, 2021, $91 million was outstanding as payable to the Service Provider (December 31, 2020: $89 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 June 30, 2021, Brookfield Infrastructure had a receivable balance of $21 million from subsidiaries of Brookfield (December 31, 2020: $21 million) and loans payable of $70 million to subsidiaries of Brookfield (December 31, 2020: $82 million). The loans are payable in full prior to the end of 2024 with interest rates ranging from 1.7% to 8.5% per annum.
Brookfield Infrastructure, from time to time, will place deposits with, or receive deposits from, Brookfield. As at June 30, 2021, our net deposit from Brookfield was $201 million (December 31, 2020: $545 million) and Brookfield Infrastructure incurred interest expense of $1 million and $2 million for three and six-month periods ended June 30, 2021, respectively (2020: $nil for the three and six-month periods). Deposits bear interest at market rates.
Brookfield Infrastructure has entered into a $500 million revolving credit facility with Brookfield to provide additional liquidity for general corporate purposes and capital expenditures, if required. As of June 30, 2021, there were no borrowings outstanding (December 31, 2020: $nil).
On April 28, 2021, Brookfield Infrastructure transferred an investment funded by our partnership on behalf of future institutional partners to Brookfield. In connection with the transfer, our partnership received approximately $25 million from Brookfield.
As at June 30, 2021, Brookfield Infrastructure had $45 million of corporate borrowings outstanding to a subsidiary of Brookfield. As at June 30, 2021, associates of Brookfield Infrastructure had $175 million of non-recourse borrowings outstanding to subsidiaries of Brookfield.

FOR THE THREE AND SIX-MONTH PERIODS ENDED JUNE 30, 2021 AND 2020
OUR OPERATIONS
We own a portfolio of infrastructure assets that are diversified by sector and by geography. We have a stable cash flow profile with approximately 95% of our Adjusted EBITDA supported by regulated or contracted revenues. In order to assist our unitholders and preferred unitholders in evaluating our performance and assessing our value, we group our businesses into operating segments based on similarities in their underlying economic drivers.
Our operating segments are summarized below:

Operating Segment |  | Asset Type |  | Primary Location
Utilities |  |  |  |
Regulated or contractual businesses which earn a return on their asset base |  | • Regulated Transmission(1) |  | • North & South America, Asia Pacific
| • Commercial & Residential Distribution(1) |  | • North & South America, Europe
Transport |  |  |  |
Provide transportation for freight, commodities and passengers |  | • Rail |  | • North & South America, Asia Pacific

1.During the fourth quarter of 2020, our partnership conducted a comprehensive review of our operating segments. To better align with how our Chief Operating Decision Maker reviews and evaluates our operations, our district energy and Indian natural gas operations were reallocated to our regulated distribution and regulated transmission subsegments, respectively, within our utilities segment. Our Australian export terminal was reallocated to our ports subsegment, within our transport segment. Our regulated distribution subsegment was renamed commercial and residential distribution, our ports subsegment was renamed diversified terminals, our energy segment was renamed to midstream and our data infrastructure segment was renamed to data.
INTRODUCTION
The following Management’s Discussion and Analysis (“MD&A”) is the responsibility of management of Brookfield Infrastructure Partners L.P. (our “partnership” collectively with its subsidiary and operating entities “Brookfield Infrastructure”). This MD&A is dated August 9, 2021 and has been approved by the Board of Directors of the general partner of our partnership for issuance as of that date. The Board of Directors carries out its responsibility for review of this document principally through its audit committee, comprised exclusively of independent directors. The audit committee reviews and, prior to its publication, approves this document, pursuant to the authority delegated to it by the Board of Directors. The terms “Brookfield Infrastructure,” “we,” “us” and “our” refer to Brookfield Infrastructure Partners L.P., and our partnership’s direct and indirect subsidiaries and operating entities as a group. This MD&A should be read in conjunction with Brookfield Infrastructure Partners L.P.’s most recently issued annual and interim financial statements. Additional information, including Brookfield Infrastructure’s Form 20-F, is available on its website at www.bip.brookfield.com, on SEDAR’s website at www.sedar.com and on EDGAR’s website at www.sec.gov/edgar.shtml.
Business Overview
Brookfield Infrastructure is a leading global infrastructure company that owns and operates high quality, essential, long-life assets in the utilities, transport, midstream and data sectors across North and South America, Asia Pacific and Europe. It is focused on assets that have contracted and regulated revenues that generate predictable and stable cash flows.
Q2 2021 INTERIM REPORT 37

Our mission is to own and operate a globally diversified portfolio of high quality infrastructure assets that will generate sustainable and growing distributions over the long term for our unitholders. To accomplish this objective, we will seek to leverage our operating segments to acquire infrastructure assets and actively manage them to extract additional value following our initial investment. As the businesses mature and cash flows have been de-risked, we seek to recycle capital and re-invest in assets that are expected to generate higher returns. An integral part of our strategy is to participate along with institutional investors in Brookfield Asset Management Inc. (together with its affiliated entities other than us, “Brookfield”) sponsored infrastructure funds that target acquisitions that suit our profile. We focus on investments in which Brookfield has sufficient influence or control to deploy an operations-oriented approach.
Performance Targets and Key Measures
We target a total return of 12% to 15% per annum on the infrastructure assets that we own, measured over the long term. We intend to generate this return from the in-place cash flows from our operations plus growth through investments in upgrades and expansions of our asset base, as well as acquisitions. We determine our distributions to unitholders based primarily on an assessment of our operating performance. Funds from Operations (“FFO”) is used to assess our operating performance and can be used on a per unit basis as a proxy for future distribution growth over the long term. In addition, we have performance measures that track the key value drivers for each of our operating segments. Refer to the “Segmented Disclosures” section of this MD&A for more detail.
Distribution Policy
Our distributions are underpinned by stable, highly regulated and contracted cash flows generated from operations. The partnership’s objective is to pay a distribution that is sustainable on a long-term basis. The partnership has set its target payout ratio at 60-70% of FFO. In sizing what we believe to be a conservative payout ratio, we typically retain approximately 15-20% of Adjusted Funds from Operations (“AFFO”) that we utilize to fund all of our internally funded growth capital expenditures.
On March 31, 2020, our partnership completed the previously announced creation of Brookfield Infrastructure Corporation (“BIPC”) with a special distribution (the “special distribution”) of class A exchangeable subordinate voting shares of BIPC (“BIPC exchangeable shares”). Each of our unitholders of record on March 20, 2020 received one BIPC exchangeable share for every nine units held. As a result of the special distribution, our partnership’s regular quarterly distribution per unit was reduced such that the aggregate distribution received by a holder of units and BIPC exchangeable shares, when taken together, remained approximately the same as it would have been had the special distribution never occurred. Therefore, the annual distribution in 2020 was $1.94 per unit, or $0.4850 per unit quarterly, as adjusted to reflect the special distribution.
In light of the current prospects for our business, the board of directors of our General Partner approved a 5% increase in our quarterly distribution to $0.51 per unit (or $2.04 per unit annualized), starting with the distribution paid in March 2021, with a proportionate increase made by the board of directors of BIPC to holders of BIPC exchangeable shares. This increase reflects the forecasted contribution from our recently commissioned capital projects, as well as the expected cash yield on acquisitions that we closed in the past year. Over the last 10 years, we have increased our annual distribution from $0.79 per unit to $2.04 per unit, a compound annual growth rate of 10%. We target 5% to 9% annual distribution growth in light of the per unit growth we foresee in our operations.
Basis of Presentation
Our unaudited interim condensed and consolidated financial statements are prepared in accordance with International Accounting Standard 34, Interim Financial Reporting (“IAS 34”) as issued by the International Accounting Standards Board (“IASB”) and using the accounting policies Brookfield Infrastructure applied in its consolidated financial statements as of and for the year-ended December 31, 2020. Our unaudited interim condensed and consolidated financial statements include the accounts of Brookfield Infrastructure and the entities over which it has control. Brookfield Infrastructure accounts for investments over which it exercises significant influence or joint control, but does not control, using the equity method.
Our partnership’s equity interests include units held by public unitholders, redeemable partnership units held by Brookfield, Exchange LP Units held by public unitholders and BIPC exchangeable shares held by public shareholders and Brookfield. Our units and the Redeemable Partnership Units have the same economic attributes in all respects, except that the Redeemable Partnership Units provide Brookfield the right to request that its units be redeemed for cash consideration. In the event that Brookfield exercises this right, our partnership has the right, at its sole discretion, to satisfy the redemption request with our units, rather than cash, on a one-for-one basis. As a result, Brookfield, as holder of Redeemable Partnership Units, participates in earnings and distributions on a per unit basis equivalent to the per unit participation of the limited partnership units of our partnership. However, given the redeemable feature referenced above, we present the Redeemable Partnership Units as a component of non-controlling interests.
In addition, Exchange LP, a subsidiary of our partnership, issued Exchange LP Units in connection with the privatization of Enercare Inc. in October 2018. Exchange LP Units 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, we present the Exchange LP Units as a separate component of non-controlling interests.
38 BROOKFIELD INFRASTRUCTURE PARTNERS L.P.

Finally, on March 31, 2020, our partnership completed the creation of BIPC with the special distribution. Each unitholder of record on March 20, 2020 received one BIPC exchangeable share for every nine units held. Holders of BIPC exchangeable shares have the right to exchange all or a portion of their shares for one unit per BIPC exchangeable share held or its cash equivalent on a fixed-for-fixed basis. BIPC or the partnership, as applicable, each have the ability to satisfy exchange requests by holders 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 the share characteristics, we present the BIPC exchangeable shares as a component of non-controlling interests.
When we discuss the results of our operating segments, we present Brookfield Infrastructure’s proportionate share of results for operations accounted for using consolidation and the equity method, in order to demonstrate the impact of key value drivers of each of these operating segments on our partnership’s overall performance. As a result, segment revenues, costs attributable to revenues, other income, interest expense, depreciation and amortization, deferred taxes, fair value adjustments and other items will differ from results presented in accordance with IFRS as they (1) include Brookfield Infrastructure’s proportionate share of earnings from investments in associates and joint ventures attributable to each of the above noted items, and (2) exclude the share of earnings (losses) of consolidated investments not held by Brookfield Infrastructure apportioned to each of the above noted items. However, net income for each segment is consistent with results presented in accordance with IFRS. Refer to the “Reconciliation of Operating Segment Measures” section of this MD&A for a reconciliation of segment results to our partnership’s statement of operating results in accordance with IFRS.
Our presentation currency and functional currency is the U.S. dollar. There were no changes in accounting policies that have had a material impact on the comparability of the results between financial years.

Three-month period ended June 30, 2021 and 2020
Net income for the three-month period ended June 30, 2021 was $1,306 million, of which income of $352 million ($0.61 per unit) was attributable to our partnership. This compares to net income of $34 million in the prior year, of which a loss of $61 million ($0.25 per unit) was attributable to our partnership. Net income increased compared to the prior year as the current period benefited from organic growth and the gain on sale of our Canadian district energy operation and our portfolio of smart meters in the U.K. These positive factors were partially offset by an increase in the future U.K. tax rate which reduced income by $178 million.
Q2 2021 INTERIM REPORT 39

Revenues for the three-month period ended June 30, 2021 were $2,663 million, which represents an increase of $717 million compared to the same period in 2020. Revenues from our data segment increased by $296 million predominately as a result of the acquisition of our Indian telecom tower operation. Revenues from our utilities segment increased by $196 million as a result of organic growth and initial contributions from our recently acquired European residential infrastructure business. Revenues from our transport segment increased by $66 million due to organic growth and return of volumes to pre-shutdown levels which was partially offset by the deconsolidation of our Australian export terminal in December 2020. Our midstream segment contributed additional revenues of $25 million predominantly as a result of organic growth. Foreign exchange increased our U.S. dollar revenues by $134 million, as all of the major currencies in which we operate appreciated against the U.S. dollar relative to the prior year.
Direct operating expenses for the three-month period ended June 30, 2021 were $1,433 million, an increase of $370 million compared to the three-month period ended June 30, 2020. Direct costs increased from the prior year due to $188 million of incremental costs associated with recently acquired businesses and $152 million of costs associated with organic growth initiatives. The impact of foreign exchange further increased our U.S. dollar costs by $76 million. These increases were partially offset by the deconsolidation of our Australian export terminal.
General and administrative expenses totaled $96 million for the three-month period ended June 30, 2021, an increase of $24 million compared to the three-month period ended June 30, 2020. This line item primarily consists of the base management fee that is paid to Brookfield, which is equal to 1.25% of the combined market value of our partnership and BIPC plus preferred units outstanding and net recourse debt. The increase from the prior year is due to a higher trading price of our units and preferred units issued during the past year.
Depreciation and amortization expense for the three-month period ended June 30, 2021 was $492 million, an increase of $117 million compared to the same period in 2020. This increase is primarily associated with incremental charges from recently completed acquisitions and foreign exchange.
Interest expense for the three-month period ended June 30, 2021 was $362 million, an increase of $115 million compared to the same period in 2020. Interest expense increased primarily as a result of additional asset-level borrowings associated with acquisitions completed during the past year.
Our partnership’s share of earnings from investments in associates and joint ventures remained consistent with the three-month period ended June 30, 2020. The impact from the partial disposition of our U.S gas pipeline in March 2021 was offset by contributions from our U.S. LNG export terminal acquired in September of last year.
Mark-to-market losses on hedging items for the three-month period ended June 30, 2021 were $15 million, compared to $75 million in the prior year. Amounts in both the current and comparative periods consist primarily of mark-to-market movements relating to foreign exchange hedging activities at the corporate level and commodity contracts at our North American gas storage operations.
Other income for the three-month period ended June 30, 2021 was $1,317 million, compared to expenses of $28 million for the same period in 2020. Current quarter results included gains recognized on the disposition of our Canadian district energy operation and our portfolio of smart meters in the U.K. These gains were partially offset by other expenses, including accretion expenses associated with the deferred consideration at our Brazilian regulated gas transmission business and asset retirement obligations.
Income tax expense for the three-month period ended June 30, 2021 was $286 million compared to $63 million for the same period in 2020. The increase is primarily due to an increase in the future U.K. income tax rate from 19% to 25% enacted in May 2021, which resulted in $178 million of additional charges. The current period was also impacted by foreign exchange, which increased our U.S. dollar tax expense by $22 million.
Six-month period ended June 30, 2021 and 2020
Net income for the six-month period ended June 30, 2021 was $1,719 million, of which income of $542 million ($0.88 per unit) was attributable to our partnership. This compares to net income of $182 million in the prior year, of which $58 million (a loss of $0.12 per unit) was attributable to our partnership. Current year results benefited from gains realized from the disposition of our Canadian district energy operation and our portfolio of smart meters in the U.K., as well as the partial disposition of our U.S. gas pipeline. Foreign exchange, fair value adjustments related to our corporate hedging program and organic growth across our segments each contributed positively to net income during the period. These positive factors were partially offset by an increase in the future U.K. tax rate which reduced income by $147 million compared to the prior year.
40 BROOKFIELD INFRASTRUCTURE PARTNERS L.P.

Revenues for the six-month period ended June 30, 2021 were $5,346 million, which represents an increase of $1,204 million compared to the same period in 2020. Our midstream segment contributed additional revenues of $229 million predominantly as a result of organic growth and operational strength and preparedness of our gas storage business through the extreme weather conditions experienced in the U.S. during the first quarter of 2021. Revenues from our data segment increased by $574 million, primarily as a result of the acquisition of our Indian telecom tower operation. Revenues from our utilities segment increased by $271 million as a result of organic growth and initial contributions from our recently acquired European residential infrastructure business. While we experienced the benefits of higher volume from our transport segment, revenues decreased by $14 million as a result of the partial disposition and deconsolidation of our Australian export terminal in December 2020. Overall, these positive impacts were further enhanced by $144 million of foreign exchange across our segments, as all of the major currencies in which we operate appreciated against the U.S. dollar relative to the prior year.
Direct operating expenses for the six-month period ended June 30, 2021 were $2,779 million, an increase of $477 million compared to the six-month period ended June 30, 2020. Direct costs increased from the prior year due to $329 million of incremental costs associated with recently acquired businesses, $123 million of costs associated with organic growth initiatives and the impact of foreign exchange, which increased our U.S. dollar costs by $111 million. These increases were partially offset by the deconsolidation of our Australian export terminal.
General and administrative expenses totaled $191 million for the six-month period ended June 30, 2021, an increase of $58 million compared to the six-month period ended June 30, 2020. This line item primarily consists of the base management fee that is paid to Brookfield, which is equal to 1.25% of the combined market value of our partnership and BIPC plus preferred units outstanding and net recourse debt. The increase from the prior year is due to a higher trading price of our units, preferred units issued during the past year, and additional borrowings incurred to fund our recent growth initiatives.
Depreciation and amortization expense for the six-month period ended June 30, 2021 was $961 million, an increase of $186 million compared to the same period in 2020. This increase is primarily associated with incremental charges from recently completed acquisitions, foreign exchange, as well as the impact of higher asset values following our annual revaluation process.
Interest expense for the six-month ended June 30, 2021 was $717 million, an increase of $188 million compared to the same period in 2020. Interest expense increased primarily as a result of additional asset-level borrowings associated with acquisitions completed during the past year, partially offset by the impact of the deconsolidation of our Australian export terminal.
Our partnership’s share of earnings from investments in associates and joint ventures was $77 million for the six-month period ended June 30, 2021, an increase of $18 million relative to the same period in 2020. The increase is the result of contributions from the acquisition of our U.S. LNG export terminal and as well organic growth.
Mark-to-market gains on hedging items for the six-month period ended June 30, 2021 were $20 million, compared to $123 million in the prior year. Amounts in both the current and comparative periods consist primarily of mark-to-market movements relating to foreign exchange hedging activities at the corporate level. The gain in the current period mainly resulted from the depreciation of several of the currencies we hedge relative to the U.S. dollar.
Other income for the six-month period ended June 30, 2021 was $1,344 million, compared to expenses of $234 million for the same period in 2020. Current quarter results included gains recognized on the disposition of a portion of our U.S. gas pipeline, our Canadian district energy operation and our smart meters portfolio in the U.K. These gains were partially offset by other expenses, including accretion expenses associated with the deferred consideration at our Brazilian regulated gas transmission business and asset retirement obligations.
Income tax expense for the six-month period ended June 30, 2021 was $420 million compared to $169 million for the same period in 2020. The increase is primarily due to an increase in the future U.K. income tax rate from 19% to 25% which resulted in $178 million of additional deferred tax charges during the second quarter of 2021, compared to $31 million in the first quarter of 2020, when the future U.K. income tax rate changed from 17% to 19%. Income tax expense further increased from the prior year as a result of organic growth, foreign exchange, and incremental charges associated with investments completed in during the past year.

Total assets were $60.3 billion at June 30, 2021, compared to $61.3 billion at December 31, 2020. Acquisitions completed in 2021, organic growth initiatives and financial asset mark-to-market movements increased consolidated assets by $2.6 billion. These increases were more than offset by the impact of dispositions completed during the year, foreign exchange and depreciation and amortization expense, which reduced total assets by $2.5 billion, $0.1 billion and $1.0 billion, respectively.
In March 2020, the World Health Organization declared a global pandemic related to COVID-19. To date, there has been significant volatility in commodity and foreign exchange markets as well as restrictions on the conduct of business in many jurisdictions and the global movement of people and certain goods. Our partnership has assessed the impact of the economic environment on our asset valuations, including our property, plant and equipment, intangible assets, and investments in associates and joint ventures. In making these assessments, we have assumed that the sharp curtailment in economic activities, as a result of social distancing rules imposed by governments worldwide, will not materially persist in the long term. Our operations have demonstrated resilience to global economic disruptions since the outbreak. Furthermore, our assets are geographically dispersed, diversified across operating segments, and largely underpinned by regulated tariffs or highly contracted cash flows. Based on our partnership’s assessment, no impairments to our asset values were required as at June 30, 2021.
As compared to December 31, 2020, property, plant and equipment decreased from $31.6 billion to $28.0 billion as the impact of recently completed acquisitions were more than offset by depreciation expense, the impact of the disposition of our Canadian district energy operation and smart meter portfolio in the U.K, foreign exchange, as well as $1.1 billion of assets reclassified as held for sale. Intangible assets increased from $11.8 billion to $12.4 billion as a result of recently completed acquisitions and the impact of foreign exchange, which were partially offset by amortization expense of $0.2 billion.
Corporate borrowings decreased by $0.3 billion since December 31, 2020. The decrease is attributable to net repayments on the revolving credit facility of $1.1 billion, partially offset by the issuance of $250 million subordinated notes, net proceeds of $496 million from our commercial paper program, and the impact of a stronger Canadian dollar relative to the U.S. dollar.
Non-recourse borrowings have remained relatively consistent as compared to December 31, 2020. The impact from recent dispositions and $0.5 billion of non-recourse borrowings reclassified as held for sale was offset by $1.1 billion of additional net borrowings primarily associated with our recent acquisitions and growth initiatives.
Partnership capital attributable to the partnership increased by $0.1 billion since December 31, 2020. The increase is attributable to income generated, partially offset by the impact of distributions paid to our unitholders.

As at June 30, 2021, our consolidated partnership capital of $21.5 billion was invested in the following currencies: United States dollars - 26%; Canadian dollars - 18%, Indian rupees - 16%; Brazilian reais - 11%; British pounds - 10%; Australian dollars - 9%; and other currencies - 10%. As a result of our currency hedging program, 65% of our partnership capital is effectively denominated in U.S. dollars. The period end rates relative to the U.S. dollar moved in opposite directions as compared to December 31, 2020. Overall, foreign currency translation decreased the carrying values of the assets and liabilities of our operations relative to December 31, 2020.

The impact of foreign currency translation on partnership capital, including those attributable to non-controlling interests for the three and six-month periods ended June 30, 2021 was a gain of $403 million and $51 million, respectively.
We use financial contracts and locally denominated debt to hedge most foreign currency exposures. We are largely hedged against the Australian, Canadian, European, British, and New Zealand currencies. As a result, the impact of currency movements was partially offset by gains and losses recognized on our currency hedges. We have also entered into hedges to reduce foreign currency exposures to the Chilean, Peruvian, and Indian currencies.
Average currency exchange rates impact the U.S. dollar equivalents of revenues and net income from non-U.S. operations on a comparative basis. With the exception of the Brazilian real, all average exchange rates for the three and six-month periods ended June 30, 2021 appreciated relative to the prior year, increasing U.S. dollar revenue and net income in these currencies.

A significant driver of our results continues to be from organic growth which consists of inflation-indexation, GDP-linked volume increases and reinvested capital. In addition, results have benefited over the last eight quarters from the contribution of new investments. On a constant currency basis, these items resulted in increases in our revenues, direct operating costs, interest charges and depreciation and amortization expense. The increases were partially offset by the impact of dispositions. In addition to the aforementioned items, net income is impacted by fair value adjustments, mark-to-market movements on derivatives, and other income and expenses.
Despite a challenging economic backdrop, our business has delivered financial results that were in line with expectations. This is attributable to significant sector and geographic diversification, ownership of long-life and essential assets, substantial barriers to entry to the sectors we operate in and, cash flows that are generated under long-term contractual or regulated frameworks. Our stable and predictable cash flow profile is further strengthened by our principled approach to counterparty selection and capital structure.
SELECTED STATEMENTS OF OPERATING RESULTS AND FINANCIAL POSITION INFORMATION
To measure performance, we focus on net income, an IFRS measure, as well as certain non-IFRS measures, including but not limited to FFO, AFFO, Adjusted EBITDA, Adjusted Earnings and Invested Capital. We define FFO as net income excluding the impact of depreciation and amortization, deferred income taxes, breakage and transaction costs, and non-cash valuation gains or losses. We define AFFO as FFO less capital expenditures required to maintain the current performance of our operations (maintenance capital expenditures). We define Adjusted EBITDA as net income excluding the impact of depreciation and amortization, interest expense, current and deferred income taxes, breakage and transaction costs, and non-cash valuation gains or losses. We define Adjusted Earnings as net income attributable to our partnership, excluding the impact of depreciation and amortization expense from revaluing property, plant and equipment and the effects of purchase price accounting, mark-to-market on hedging items and disposition gains or losses. We define Invested Capital as partnership capital removing the following items: non-controlling interest - in operating subsidiaries, retained earnings or deficit, accumulated other comprehensive income and ownership changes.
Along with net income and other IFRS measures, FFO, Adjusted EBITDA, Adjusted Earnings and Invested Capital are key measures of our financial performance that we use to assess the results and performance of our operations on a segmented basis. AFFO is also a measure of operating performance and represents the ability of our businesses to generate sustainable earnings. Adjusted Earnings is a measure of operating performance used to assess the ability of our businesses to generate recurring earnings, which allows users to better understand and evaluate the underlying financial performance of our partnership. 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.
44 BROOKFIELD INFRASTRUCTURE PARTNERS L.P.

Since they are not calculated in accordance with, and do not have any standardized meanings prescribed by IFRS, FFO, AFFO, Adjusted EBITDA, Adjusted Earnings and Invested Capital are unlikely to be comparable to similar measures presented by other issuers and have limitations as analytical tools. Specifically, our definition of FFO may differ from the definition used by other organizations, as well as the definition of Funds from Operations used by the Real Property Association of Canada (“REALPAC”) and the National Association of Real Estate Investment Trusts, Inc. (“NAREIT”), in part because the NAREIT definition is based on U.S. GAAP, as opposed to IFRS.
For further details regarding our use of FFO, AFFO, Adjusted EBITDA, Adjusted Earnings and Invested Capital, as well as a reconciliation of the most directly comparable IFRS measures to these measures, see the “Reconciliation of Non-IFRS Financial Measures” section of this MD&A.

SEGMENTED DISCLOSURES
In this section, we review the results of our principal operating segments: utilities, transport, midstream and data. Each segment is presented on a proportionate basis, taking into account Brookfield Infrastructure’s ownership in operations accounted for using the consolidation and equity methods, whereby our partnership either controls or exercises significant influence or joint control over its investments. Refer to the “Discussion of Segment Reconciling Items” of this MD&A for a reconciliation of segment results to our partnership’s statement of operating results in accordance with IFRS.
Our utilities segment is comprised of businesses from which we earn a return on a regulated or notionally stipulated asset base, which we refer to as the rate base, or from revenues in accordance with long-term concession agreements, private bilateral contracts approved or ratified by the regulator, or price control frameworks. These include our regulated transmission (natural gas and electricity) and commercial and residential distribution (electricity, district energy and natural gas connections) operations. Our rate base increases with capital that we invest to upgrade and expand our systems. Depending on the jurisdiction, our rate base may also increase by inflation and maintenance capital expenditures and decrease by regulatory depreciation. The return that we earn is typically determined by a regulator for prescribed periods of time. Thereafter, it may be subject to customary reviews based upon established criteria. Our diversified portfolio of assets allows us to mitigate exposure to any single regulatory regime.
Due to the franchise frameworks and economies of scale of our utilities businesses, we often have significant competitive advantages in competing for projects to expand our rate base and earn incremental revenues. Accordingly, we expect this segment to produce stable revenue and margins over time that should increase with investment of additional capital and inflation. Nearly all our utilities segment’s Adjusted EBITDA is supported by regulated or contractual revenues.
The objectives for our utilities segment are to invest capital in the expansion of our rate base, as well as to provide safe and reliable service for our customers on a cost-efficient basis. If we do so, we will be in a position to earn an appropriate return on our rate base and strengthen our market position. Our performance can be measured by the growth in our rate base, the return on our rate base, and the growth in our AFFO.
Our utilities segment is comprised of the following:
Regulated Transmission
•Approximately 5,300 kilometers of transmission lines in Brazil, of which approximately 2,700 kilometers are operational
•Approximately 4,200 kilometers of natural gas pipelines in North America, South America, and India
Commercial and Residential Distribution
•Approximately 7.0 million connections, predominantly electricity and natural gas
•Provides residential infrastructure, including water heater, heating, ventilation, and air conditioner (“HVAC”) rentals, as well as other essential home services to approximately 1.9 million customers annually in Canada and the United States
•Approximately 330,000 long-term contracted sub-metering services within Canada

2.Return on rate base is Adjusted EBITDA divided by time weighted average rate base.
3.Return on rate base excludes impact of connections revenue at our U.K. regulated distribution business, a return of capital component from earnings generated at our Brazilian transmission businesses and our North America district energy operation as we agreed to sell the business in February 2021.
Our partnership earns a return on a regulated or notionally stipulated asset base, which we refer to as rate base. Our rate base reflects the current amount, either as defined by the regulator or as implied by our contracted cash flows, on which we earn our return. Our rate base increases with capital that we invest to expand our systems and is indexed to local inflation. The return that we earn is typically determined by a regulator for prescribed periods of time or is derived based on the contracted cash flows that we have secured. We believe that the rate base is useful for investors as it provides them with an understanding of the unlevered returns that our asset base can currently generate and enhances comparability across other utility investments as it assists in assessing the operating performance of our businesses by eliminating the effect of its current capital structure and tax profile.
For the three-month period ended June 30, 2021, our utilities segment generated FFO of $190 million, compared to $157 million for the same period in the prior year. FFO increased by 21% due to a recovery in connections activity at our U.K. regulated distribution business, as well as organic growth driven by inflation indexation and capital commissioned into rate base. Results further benefited from the contribution associated with the acquisition of the remaining interest in our Brazilian regulated gas transmission operation completed at the end of April. These positive factors were partially offset by the sale of our smart meter portfolio and North American transmission operation.
The following table presents our proportionate Adjusted EBITDA and FFO for the businesses in this operating segment:

For the three-month period ended June 30, 2021, our commercial and residential distribution operations generated Adjusted EBITDA of $141 million and FFO of $113 million, compared to $120 million and $96 million, respectively, in the prior year. Adjusted EBITDA and FFO benefited from inflation indexation, capital commissioned into rate base over the last 12 months, and a recovery in connections activity at our U.K. regulated distribution business. These positive factors were partially offset by the loss of earnings associated with the sale of our portfolio of smart meters in the U.K. completed in May.
For the three-month period ended June 30, 2021, our regulated transmission operations generated Adjusted EBITDA of $110 million and FFO of $77 million, compared to $83 million and $61 million, respectively, in the prior year. Adjusted EBITDA and FFO benefited from a 24% annual inflationary tariff adjustment at our Brazilian regulated gas transmission operation, the ongoing expansion of our Brazilian electricity transmission network and the acquisition of the remaining 10% interest in our Brazilian regulated gas transmission business. These positive factors were partially offset by the loss of earnings from the sale of our North American transmission operation.

As of June 30, 2021, total capital to be commissioned was $940 million compared to $1,072 million as of December 31, 2020. Total capital to be commissioned decreased as new capital project mandates awarded during the period were more than offset by capital projects commissioned into rate base and the impact of asset sales.
Q2 2021 INTERIM REPORT 49

Our transport segment is comprised of infrastructure assets that provide transportation, storage and handling services for freight, commodities and passengers, for which we are generally paid an access fee. Profitability is based on the volume and price achieved for the provision of access and associated services. This operating segment is comprised of businesses, such as our rail and toll road operations, which may be subject to price ceiling or other rate regulation focused on maintaining competition, as well as diversified terminal operations which are highly contracted and subject to the regulatory regimes applicable to the goods they handle. Transport businesses typically have high barriers to entry and, in many instances, have very few substitutes in their local markets. While these businesses have greater sensitivity to market prices and volume than our other operating segments, revenues are generally stable and, in many cases, are supported by contracts or customer relationships. The diversification within our transport segment mitigates the impact of fluctuations in demand from any particular sector, commodity or customer. Approximately 85% of our transport segment’s Adjusted EBITDA is supported by contractual or regulated revenues.
Our objectives for our transport segment are to provide safe and reliable service to our customers and to satisfy their growth requirements by increasing the utilization of our assets and expanding our capacity in a capital efficient manner. If we do so, we will be able to charge an appropriate price for our services and earn an attractive return on the capital deployed. Our performance can be measured by our revenue growth and our Adjusted EBITDA margin.
Our transport segment is comprised of the following:
Rail
•116 short line freight railroads comprising over 22,000 kilometers of track in North America and Europe
•Sole provider of rail network in southern half of Western Australia with approximately 5,500 kilometers of track and operator of approximately 4,800 kilometers of rail in Brazil
Toll Roads
•Approximately 3,800 kilometers of motorways in Brazil, Chile, Peru and India
Diversified Terminals
•13 terminals in North America, U.K., and Australia facilitating global trade of natural resources and commodities
•An approximately 25 million tonnes per annum (“mtpa”) LNG export terminal in the United States
•An 85 million tonnes per annum export facility in Australia

For the three-month period ended June 30, 2021, our rail business generated Adjusted EBITDA of $95 million and FFO of $77 million compared to $81 million and $65 million, respectively, in the prior year. Adjusted EBITDA and FFO benefited from a 4% increase in volumes across our rail business due to higher economic activity in the U.S., a new task in Australia and a strong agriculture harvest in Brazil.
For the three-month period ended June 30, 2021, our toll roads contributed Adjusted EBITDA of $53 million and FFO of $37 million compared to $40 million and $25 million, respectively, in the prior year. Adjusted EBITDA and FFO increased due to the return to pre-shutdown traffic volumes which were partially offset by the planned hand-back of a state concession at our Brazilian toll road operation.
For the three-month period ended June 30, 2021, our diversified terminal operations reported Adjusted EBITDA of $91 million and FFO of $59 million compared to $53 million and $37 million, respectively, in the prior year. Adjusted EBITDA and FFO benefited from the contribution from our U.S. LNG export terminal acquired last year and an 18% increase in container and bulk volumes driven by a recovery in economic activity. These positive factors were partially offset by the loss of earnings associated with the partial sale of our Australian export terminal completed in the fourth quarter of 2020.

Our midstream segment is comprised of systems that provide natural gas transmission, gathering and processing, and storage services. Profitability is based on the volume and price achieved for the provision of these services. This operating segment is comprised of businesses that are subject to regulation, such as our natural gas pipelines whose services are subject to price ceilings. Midstream businesses typically have high barriers to entry as a result of significant fixed costs combined with economies of scale or unique positions in their local markets. Although these businesses have greater sensitivity to market prices and volume than our utilities segment, revenues are typically contracted with varying durations and are relatively stable.
Our objectives for our midstream segment are to provide safe and reliable service to our customers and to satisfy their growth requirements by increasing the utilization of our assets and expanding our capacity in a capital efficient manner. If we do so, we will be able to charge an appropriate price for our services and earn an attractive return on the capital deployed. Our performance can be measured by our revenue growth, our Adjusted EBITDA margin and our growth in AFFO.
Our midstream segment is comprised of the following:
•Approximately 15,000 kilometers of natural gas transmission pipelines in the United States
•Approximately 600 Bcf of natural gas storage in the United States and Canada
•16 natural gas processing plants with approximately 2.9 Bcf per day of gross processing capacity and approximately 3,400 kilometers of gas gathering pipelines in Canada

For the three-month period ended June 30, 2021, our data transmission and distribution operations generated Adjusted EBITDA of $72 million and FFO of $53 million, compared to $40 million and $35 million, respectively, in the prior year. Adjusted EBITDA and FFO benefited from the roll-out of growth initiatives at our French telecom business and the contribution from our Indian telecom business acquired last year. The roll-out of our build-to-suit tower program at our French telecom business is accelerating, with approximately 265 sites added over the last 12 months supported by record activations in June.
For the three-month period ended June 30, 2021, our data storage operations generated Adjusted EBITDA of $12 million and FFO of $7 million, compared to $13 million and $8 million, respectively, in the prior year. Adjusted EBITDA and FFO decreased as the contribution from capacity commissioned at our Brazilian data center operation over the last 12 months was more than offset by lower sales at our U.S. operation.
The following table presents the roll-forward of our proportionate share of capital backlog and capital to be commissioned:

As of June 30, 2021, total capital to be commissioned was $507 million compared to $415 million as of December 31, 2020. Capital to be commissioned increased primarily due to additional capital project mandates at our Australian data centers and our fibre-to-the-home program at our French telecom business, partially offset by capital commissioned during the period.

For the three-month period ended June 30, 2021, Adjusted EBITDA and FFO for our Corporate segment were losses of $96 million and $89 million, compared to $72 million and $54 million, respectively, in the prior year. Adjusted EBITDA and FFO decreased over the prior year as a result of a higher base management fee due to an increase in our unit price.
Pursuant to our Master Services Agreement, we pay Brookfield an annual base management fee equal to 1.25% of the combined market value of our partnership and BIPC plus preferred units outstanding and net recourse debt. The base management fee of $93 million increased over the prior year due to a higher unit price and capital market activity used to fund new growth initiatives.
CAPITAL RESOURCES AND LIQUIDITY
The nature of our asset base and the quality of our associated cash flows enable us to maintain a stable and low-cost capital structure. We attempt to maintain sufficient financial liquidity at all times so that we are able to participate in attractive opportunities as they arise, better withstand sudden adverse changes in economic circumstances and maintain our distribution to unitholders. Our principal sources of liquidity are cash flows from our operations, undrawn credit facilities and access to public and private capital markets. We also structure the ownership of our assets to enhance our ability to monetize them to provide additional liquidity, if necessary. In certain instances, subsidiaries may be subject to limitations on their ability to declare and pay dividends to our partnership. However, no significant limitations existed at June 30, 2021 and December 31, 2020.
Our group-wide liquidity at June 30, 2021, consisted of the following:

1.Corporate cash and financial assets, commercial paper and deposit from parent are presented on a proforma basis to include the proceeds from the sale of our U.S. district energy business. Subordinated corporate credit facility is presented on a proforma basis to include a $1 billion commitment from Brookfield in support of our bid to acquire Inter Pipeline Ltd. (conditional on a successful tender offer)
2.Includes a $1,975 million committed corporate credit facility and a $1 billion temporary bulge facility. As of June 30, 2021, our committed corporate credit facility and temporary bulge facility were undrawn and we had commercial paper outstanding of $496 million
3.Brookfield Infrastructure, from time to time, will place deposits with, or receive deposits from Brookfield. The deposit bears interest at market rates and was provided to Brookfield Infrastructure to utilize excess cash held by the parent to repay Brookfield Infrastructure’s draws on the corporate credit facility
We believe that group-wide liquidity is sufficient to meet Brookfield Infrastructure’s present requirements. We finished the quarter with group-wide liquidity of $5.0 billion, a significant increase over our liquidity position as at December 31, 2020 due to several asset sales and capital markets activity during the year.

Proportionate debt is presented to assist investors in understanding the capital structure of our underlying investments that are consolidated in our financial statements but are not wholly-owned. When used in conjunction with Adjusted EBITDA, proportionate debt is expected to provide useful information as to how the partnership has financed its businesses at the asset-level. The only differences between consolidated debt presented under IFRS and proportionate debt are the adjustments to remove the share of debt of consolidated investments not held by our partnership and to add proportionate debt of investments in associates. Management utilizes proportionate debt in understanding the capital structure of our underlying investments that are consolidated in our financial statements, but are not wholly-owned, and our investments in associates and joint ventures. Proportionate debt provides useful information as to how our partnership has financed its businesses at the asset-level and provides a view into our return on capital
that we invest at a given degree of leverage.

2.Represents non-recourse debt to Brookfield Infrastructure as the holders have recourse only to the underlying operations.
3.As of June 30, 2021, approximately $150 million of proportionate net debt was in breach of asset-level financial covenants. This equates to approximately 1% of total proportionate debt of the partnership. 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.
4.As of June 30, 2021, approximately 37% has been issued as floating rate debt. Brookfield Infrastructure and its subsidiaries have entered into interest rate swaps whereby the floating rate debt has been converted to fixed rate debt, effectively reducing floating rate debt maturities to approximately 25% of our total borrowings. Excluding working capital and capital expenditure facilities, floating rate debt maturities are approximately 23% of our total borrowings, inclusive of the impact of interest rate swaps.
Our asset-level debt has an average term of seven years. On a proportionate basis, our net debt-to-capitalization ratio, defined as proportionate net debt divided by proportionate net debt plus invested capital, as of June 30, 2021 was 59%. The weighted average cash interest rate is 4.5% for the overall business (June 30, 2020: 4.1%), in which our utilities, transport, midstream, data and corporate segments were 4.1%, 4.8%, 5.4%, 4.5% and 4.2%, respectively (June 30, 2020: 4.2%, 4.7%, 5.4%, 3.5% and 3.0%).

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 life, divided by the weighted average Invested Capital for the period.
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.
Weighted average Invested Capital for the three and six-month periods ended June 30, 2021 were $9,410 million and $9,386 million, respectively. Refer to the “Reconciliation of Non-IFRS Financial Measures” section of this MD&A for more details.

This fee is estimated to be approximately $372 million per year based on the June 30, 2021 market capitalization of our partnership plus preferred units and recourse corporate net debt.
An integral part of our partnership’s strategy is to participate with institutional investors in Brookfield-sponsored private infrastructure funds that target acquisitions that suit Brookfield Infrastructure’s profile. In the normal course of business, our partnership has made commitments to Brookfield-sponsored private infrastructure funds to participate in these target acquisitions in the future, if and when identified.

FINANCIAL INSTRUMENTS
Foreign Currency Hedging Strategy
To the extent that we believe it is economic to do so, our strategy is to hedge a portion of our equity investments and/or cash flows exposed to foreign currencies. The following key principles form the basis of our foreign currency hedging strategy:
•We leverage any natural hedges that may exist within our operations
•We utilize local currency debt financing to the extent possible
•We may utilize derivative contracts to the extent that natural hedges are insufficient
The table below presents our hedged position in foreign currencies as of June 30, 2021. The adjusted equity investment balances reflect the book value of our assets as of June 30, 2021 which contains certain limitations when evaluating our hedge exposure. Most importantly, all intangible assets and growth opportunities are not eligible for revaluation. As such, our book values are lower than fair value which is evident in the below table.

At June 30, 2021, 65% of our net equity investment is U.S. dollar functional. For the three-month period ended June 30, 2021, we recorded losses in comprehensive income of $8 million (June 30, 2020: losses of $154 million) related to these contracts.
CAPITAL REINVESTMENT
We fund growth capital expenditures with cash flow generated from operations, supplemented by non-recourse debt sized to investment grade coverage and covenant thresholds. This is designed to ensure that our investments have stable capital structures supported by a substantial level of equity and that cash flows at the asset level can be remitted freely to the partnership. This strategy also underpins our investment grade profile.
To fund large scale development projects and acquisitions, we will evaluate a variety of capital sources including proceeds from selling mature businesses, in addition to raising money in the capital markets through equity, debt and preferred share issuances. Furthermore, the partnership has $2.975 billion of committed revolving credit facilities available for investments and acquisitions, as well as funding the equity component of organic growth initiatives. The facilities are intended, and have historically been used, as a bridge to a long-term financing strategy rather than a permanent source of capital.

We present cash flows generated by our businesses on a proportionate basis as approximately 40% of our FFO is generated by investments that are not consolidated in our financial statements. The partnership participates in arrangements such as joint ventures or consortiums which provide it with access to partners with local strategic expertise and substantial amounts of capital. When investing in such arrangements, which are not consolidated for financial statement purposes, the partnership nevertheless maintains joint control or significant influence over the business, and is therefore, not a passive investor. We structure governance arrangements to require each of our businesses to distribute all available cash (which is generally defined as cash on hand less any amounts reserved for committed growth projects as approved by the investment’s Board of Directors), ensuring that any decision to not distribute all available cash flow requires our express consent. Consequently, the partnership has access to operating cash flows generated by all of our businesses, including joint ventures and any non-consolidated investments.
The following table highlights the significance of operating cash flow generated from investments which are not consolidated in our financial statements and reconciles consolidated cash flow from operations to AFFO.

1.By removing cash from operating activities attributable to non-controlling interests, the partnership is able to present AFFO attributable to the partnership. We believe our proportionate financial information, when read in conjunction with the partnership’s reported results under IFRS, provides the most meaningful assessment of how our operations are performing. Please refer to the discussion of the limitations of proportional results as an analytical tool within the “Reconciliation of Non-IFRS Financial Measures” section on this MD&A.
2.The most closely related IFRS measure to AFFO is net income. However, occasionally, we believe the alternative reconciliation can be useful and have therefore provided this reconciliation of consolidated cash flow from operations to AFFO. Please see the “Reconciliation of Non-IFRS Financial Measures” section of this MD&A for a reconciliation of AFFO to net income.

From a treasury management perspective, the partnership manages its cash reserves with a view of minimizing foreign exchange and administrative costs, as well as enhancing our ability to secure asset level debt financing. While capital is primarily raised at the corporate level to fund the equity component of organic growth capital expenditures, actual funding of projects may be executed by injecting cash into subsidiaries or utilizing operating cash flow generated and retained by the business. Importantly, the physical movement of cash has no relevance on Brookfield Infrastructure’s ability to fund capital expenditures or make distributions.
DISTRIBUTION POLICY
Our distributions are underpinned by stable, highly regulated and contracted cash flows generated from operations. The partnership’s objective is to pay a distribution that is sustainable on a long-term basis. The partnership has set its target payout ratio at 60-70% of Funds from Operations. In sizing what we believe to be a conservative payout ratio, we typically retain approximately 15-20% of AFFO that we utilize to fund some or all of our internally funded growth capital expenditures.
The following table presents the partnership’s payout ratios:

2.After adjusting for a Brazilian real of 4.20 (the rate prior to the impact of the economic shutdowns), FFO and AFFO payout ratios for the three-month period ended June 30, 2021 were 72% and 91%, respectively.
The partnership’s annual distribution is reviewed with the Board of Directors in the first quarter of each year considering the following:
i) The results from the prior year as well as the budget for the upcoming year and the five-year business plan based on the partnership’s share of Funds from Operations generated by our assets;
ii) The partnership’s group-wide liquidity and its ability to fund committed capital investments.
CAPITAL EXPENDITURES
Due to the capital-intensive nature of our partnership’s asset base, ongoing capital investment is required for additions and enhancements, life-cycle maintenance and repair of plant and equipment related to our operations. Our partnership reviews all capital expenditures and classifies them in one of the two following categories:
i)Growth capital expenditures: capital outlays underpinned by incremental revenues that will enhance our partnerships’ returns. These projects are eligible for inclusion in the rate base of our utilities segment, or they are meant to add capacity to further expand our existing infrastructure networks in our transport, midstream and data operations;
ii)Maintenance capital expenditures: required capital outlays to maintain the current operating state and reliability of the system while ensuring regulatory and safety requirements are upheld.
We manage separate review and approval processes for each of the two categories of capital expenditures. Growth capital expenditures are underwritten in isolation and must meet our partnership’s target after-tax equity return threshold of 12-15%. Projects that meet these return targets are presented to the Capital Expenditure Committee which comprises senior personnel of the General Partner of our partnership. The committee reviews proposed project plans considering the target returns and funding plans, in addition to analyzing the various execution risks associated with these projects. Once a project receives approval from the Capital Expenditure Committee, it is generally added to the backlog.
Q2 2021 INTERIM REPORT 63

Maintenance capital expenditures follow a different, though equally robust process, as failure to make necessary investment to maintain our operations could impair the ability of our businesses to serve our customer base or continue existing operations. Firstly, the operations teams involved with a particular business performs a detailed review of all planned and proposed maintenance capital expenditures during the annual budgeting process. These plans are reviewed in the context of the business’ maintenance capital approach that is agreed upon with our partnership at the time of acquisition and take into account drivers of performance that include public and worker health and safety, environmental and regulatory compliance, system reliability and integrity. Maintenance capital projects that receive approval at the asset level are then presented to our partnership’s corporate asset management teams that are responsible for overseeing our partnership’s operations, and have ample experience in managing utilities, transport, midstream and data assets. Through an iterative process with the companies’ senior operating executives, the plan is refined through a comprehensive review including prioritization of non-discretionary projects and comparisons to industry benchmarks. Once agreed, maintenance capital expenditure plans are approved and form part of the annual and five-year business plans that are presented to our partnership’s senior executive team. Once approved, these maintenance plans are executed in the following year and performance relative to these plans is closely monitored by both the operations and asset management teams.
In addition to the various levels of internal reviews, our partnership engages a reputable, globally recognized engineering services firm annually to perform an independent review of its overall approach to maintenance capital expenditures and detailed capital program. Each year the engineering services firm will review a portion of the portfolio, covering all assets on a rotating basis. For each asset under review in a given year, the engineering services firm will review the historical and forecasted spend against industry standards, regulatory requirements or other benchmarking data, and determine the reasonableness of the maintenance capex program based on the nature of the business and the age and condition of the assets. We have also engaged an accounting firm to review the findings of the report provided by the engineering services firm and to assess the control activities related to our process for compiling the annual sustaining maintenance capital expenditure ranges by segment. The results from the engagements confirm that our stated ranges of annual sustaining maintenance capital expenditures are reasonable and in-line with industry standard for assets of a similar nature.
The following table presents the components of growth capital expenditures by operating segment:

| For the three-month period ended June 30 |  | For the six-month period ended June 30

Growth capital expenditures for the three-month period ended June 30, 2021 were $237 million, an increase from $184 million during the same period in 2020. The increase in growth capital expenditures is primarily due to growth projects at our recently acquired U.S. LNG export terminal and Indian telecom business, as well as increased spending to expand capacity at our rail operations in Australia and Brazil. These increases were partially offset by the completion of major projects at our U.S. gas pipeline and western Canadian natural gas midstream business.

Maintenance capital expenditures for the three-month period ended June 30, 2021 were $84 million, a $16 million increase from the same period in 2020. Maintenance capital expenditures increased due to higher spend at our transport segment resulting from a recovery in volumes from last year, as well as the timing of spend at our New Zealand data distribution business. We estimate annual maintenance capital expenditures to be $40-45 million, $155-165 million, $90-100 million, and $35-40 million for our utilities, transport, midstream, and data segments, respectively, for a total range between $320-350 million. As at June 30, 2021, our maintenance capital expenditures were below our estimated range primarily due to the timing of maintenance spend at our transport and midstream segments. Our partnership leverages industry data and benchmarks provided by a global engineering services firm to determine the appropriate maintenance capital ranges as disclosed above.
DEPRECIATION, AMORTIZATION AND RETURN OF CAPITAL ESTIMATES
When determining the fair value, useful life and residual value of essential, long-life infrastructure investments, certain judgments and estimates are used. As a result, our partnership’s depreciation and amortization is not directly comparable to the level of capital required to maintain the structural integrity and safety of our physical assets and their operating cash flow profile. There are three distinct limitations with using our partnership’s accounting depreciation as a proxy for annual maintenance capital requirements which are as follows:
i)The partnership has elected to revalue property, plant and equipment (“PP&E”) annually under IFRS. Each year we assess the fair value of our PP&E by reviewing the discounted cash flows that we expect to receive from the underlying business. The revaluation gains we have recorded reflect our ability to increase the cash flows generated from these businesses, the reinvestment of cash flows into both maintenance capital and accretive organic growth projects, and the increasing institutional demand for de-risked mature investments in the current low interest rate environment. While revaluation gains correspond to increasing values for our shareholders, they also lead to higher depreciation expense as we amortize a higher asset valuation over the same useful life estimate. However, this increase in reported depreciation often does not correspond to an increase in the cost to maintain the physical asset base. We estimate that revaluation gains alone result in an increase in our reported depreciation by almost 25% over the last three years.
ii)Due to the nature of our investments, historically, a significant portion of purchase price allocations was ascribed to PP&E. This allocation has a similar effect to the revaluation approach in that it increases depreciation expense during our ownership period. A recent example of this would be our acquisition of the leading independent telecom tower operator in France. The business generates stable, inflation-linked cash flows underpinned by long-term contracts with its customers. For the purposes of the purchase price allocation, we used an internal discounted cash flow model to allocate the consideration paid to PP&E (the physical towers) and intangible assets (the long-term customer relationships with our tenants). This business had limited goodwill ascribed to it and therefore resulted in a carrying value of PP&E far in excess of the seller’s previously depreciated cost base. As a result, the annual depreciation expense that we recognize is significantly higher than would have been recognized by the seller. Similar to the first point, the cash flow expected to be generated from the investment results in a premium to the physical replacement cost which further expands the disconnect between accounting depreciation and the true cost to maintain these assets. Today, we estimate that almost 30% of our proportionate depreciation and amortization expense is the result of the method of allocating the initial purchase price allocation primarily to depreciable asset classes.
iii)Depreciation over accounting useful life is not always reflective of annual maintenance expenditures as many of our infrastructure assets have very minimal maintenance requirements. An illustrative example of this is our U.K. regulated distribution business, the largest independent ‘last mile’ gas and electricity connection provider in the country with over two million multi-utility connections in place today. Under our adopted accounting standards, IFRS, we are required to depreciate the network over a period of up to 60 years. However, our network assets, which consist primarily of nearly indestructible pipes installed several feet underground, require minimal on-going maintenance.
Q2 2021 INTERIM REPORT 65

Some of our utility and transport investments are owned and operated under concessions which can further cause depreciation and amortization to exceed maintenance requirements. Essential infrastructure assets are often owned through arrangements which grant the concessionaire the right to operate the investment for a specified period of time. This is common in certain asset classes, such as toll roads, where the assets revert to the regulator at the end of the specified time period. Our partnership’s largest concession-based investments are in our Brazilian toll road business and our Brazilian regulated natural gas transmission operations. These concessions are for a subset of the asset’s useful life, and therefore annual maintenance capital during a concession term may be less than required over its full useful life (for example, toll roads in North and South America could last up to 100 years, however concession periods can range between 20-40 years). 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 will be amortized on a straight-line basis over the estimated useful life of the underlying infrastructure.
Different from the many perpetual franchises we own, cash flow streams over an investment period of concession arrangements will include the return of capital invested. As such, we believe investors should understand the portion of our cash flows that we estimate are a return of capital. We complete this estimate by reviewing the cash flow profile over the concession period as underwritten, and estimate the percentage of cash flows generated in a given year. This percentage is then applied to our invested capital to determine how much capital we believe was returned in the current year.
The following table summarizes the return of capital estimates for the three and six-month periods ended June 30, 2021 and June 30, 2020:

| For the three-month period ended June 30 |  | For the six-month period ended June 30

1.Refer to the “Reconciliation of Non-IFRS Financial Measures” for additional information. Return of capital is used in the calculation of return on Invested Capital, a non-IFRS financial measure.
Although helpful in the context of understanding the operating performance of our business, we believe reducing our operating cash flows by return of capital to develop an alternative estimate of the long-term cash flow generating abilities of our partnership is not appropriate. Such an estimate would not take into account changes in the value of the business as a result of our strategic initiatives. When acquiring these concession rights, we focus on surrounding these assets with an experienced management team and a platform for growth. As concession agreements are transferable, we plan on monetizing these investments as part of our broader capital recycling initiatives, as we recently did at our Chilean toll road operation. We acquired this concession-based business for $340 million during 2011 and 2012. Through the reinvestment of cash flows, a stable capital structure and building a strong management team, we were able to sell two-thirds of this business for net-to-BIP after-tax proceeds of approximately $530 million while having eight fewer years remaining on the concession. This asset sale resulted in a local currency IRR of 22% over the eight-year hold period. Although we attribute a portion of cash flows as return of capital, the value of our assets under finite life concession arrangements does not necessarily decrease over time in part because with strong teams running the business, and overall GDP growth requiring more infrastructure, the potential to secure further assets or expand existing assets is valuable. In the case of our Chilean toll road business, we realized proceeds well in excess of the capital we invested through monetizations during 2020 and 2019.
To enhance the comparability of our financial statements and non-IFRS metrics, we encourage investors to consider the maintenance capital expenditure ranges and return of capital estimates included in our disclosures. These disclosures, when combined with our IFRS and non-IFRS measures, will provide users with a fulsome view of our operating performance over time.

This statement reflects activities within our consolidated operations and therefore excludes activities within non-consolidated entities.
Three-month period ended June 30, 2021 and 2020
Cash from operating activities
Cash from operating activities totaled $0.6 billion for the three-month period ended June 30, 2021, marginally less than the cash generated during the same period in 2020. The reduction was primarily due to changes in working capital, which decreased by $269 million. This decrease was partially offset by contributions from recently completed acquisitions and foreign exchange.
Cash from (used by) investing activities
Cash from investing activities totaled $2.0 billion for the three-month period ended June 30, 2021, as compared to $0.4 billion used during the same period in 2020. The current period includes $2.6 billion of proceeds from the disposition of our Canadian district energy operation and smart meter portfolio in the U.K., partially offset by $0.5 billion of net capital invested in long-lived assets and financial assets. The prior period included $0.4 billion of net capital invested in long-lived assets and financial assets.
Cash used by financing activities
Cash used by financing activities totaled $2.5 billion for the three-month period ended June 30, 2021, $2.4 billion more than the same period in 2020. The current period included $1.7 billion of net capital provided to non-controlling interests, which included proceeds from dispositions completed during the quarter, the repayment of a $0.7 billion deposit to our parent, $0.3 billion paid to non-controlling interests for the partial acquisition of our Brazilian regulated transmission business, $0.3 billion of distributions paid to unitholders, and $0.3 billion of lease liability repaid and other. These outflows were partially offset by $0.8 billion of net proceeds from borrowings. The prior period included $0.1 billion of net capital paid to non-controlling interests and $0.3 billion of distributions paid to unitholders, partially offset by net proceeds from borrowings of $0.3 billion.
PARTNERSHIP CAPITAL
The total number of partnership units in the Holding LP outstanding is comprised of the following:

| As of
| June 30, 2021 |  | December 31, 2020
Redeemable Partnership Units, held by Brookfield | 121,952,992 |  |  | 121,952,992 |
Special General Partner Units | 1,600,410 |  |  | 1,600,410 |
Managing General Partner Units | 295,606,411 |  |  | 295,429,987 |
Total | 419,159,813 |  |  | 418,983,389 |

An affiliate of Brookfield in its capacity as the special general partner of the Holding LP is entitled to incentive distributions which are based on the amount by which quarterly distributions on the limited partnership units, the exchange LP units and the BIPC exchangeable shares exceed specified target levels. To the extent distributions on the limited partnership units, Exchange LP units and BIPC exchangeable shares exceed $0.1827 per unit/share per quarter, the incentive distribution rights entitle the special general partner to 15% of incremental distributions above this threshold to $0.198 per unit/share.
To the extent that distributions on limited partnership units, Exchange LP units and BIPC exchangeable shares exceed $0.198 per unit/share, the incentive distribution rights entitled the special general partner to 25% of incremental distributions above this threshold.

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 less than $1 million were incurred during the three and six-month periods ended June 30, 2021 (2020: less than $1 million for the three and six-month periods).
Since inception, Brookfield Infrastructure has had a management agreement (the “Master Services Agreement”) with certain service providers (the “Service Provider”), 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 Provider equal to 0.3125% per quarter (1.25% annually) of the market value of our partnership. The Base Management Fee was $93 million and $185 million respectively, for the three and six-month periods ended June 30, 2021 (2020: $69 million and $128 million). As of June 30, 2021, $91 million was outstanding as payable to the Service Provider (December 31, 2020: $89 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 June 30, 2021, Brookfield Infrastructure had a receivable balance of $21 million from subsidiaries of Brookfield (December 31, 2020: $21 million) and loans payable of $70 million to subsidiaries of Brookfield (December 31, 2020: $82 million). The loans are payable in full prior to the end of 2024 with interest rates ranging from 1.7% to 8.5% per annum.
Brookfield Infrastructure, from time to time, will place deposits with, or receive deposits from, Brookfield. As at June 30, 2021, our net deposit from Brookfield was $201 million (December 31, 2020: $545 million) and Brookfield Infrastructure incurred interest expense of $1 million and $2 million for three and six-month periods ended June 30, 2021, respectively (2020: $nil for the three and six-month periods). Deposits bear interest at market rates.
68 BROOKFIELD INFRASTRUCTURE PARTNERS L.P.

Brookfield Infrastructure has entered into a $500 million revolving credit facility with Brookfield to provide additional liquidity for general corporate purposes and capital expenditures, if required. As of June 30, 2021, there were no borrowings outstanding (December 31, 2020: $nil).
On April 28, 2021, Brookfield Infrastructure transferred an investment funded by our partnership on behalf of future institutional partners to Brookfield. In connection with the transfer, our partnership received approximately $25 million from Brookfield.
As at June 30, 2021, Brookfield Infrastructure had $45 million of corporate borrowings outstanding to a subsidiary of Brookfield. As at June 30, 2021, associates of Brookfield Infrastructure had $175 million of non-recourse borrowings outstanding to subsidiaries of Brookfield.
Brookfield Infrastructure’s subsidiaries provide heating, cooling and connection services in the normal course of operations on market terms to subsidiaries and associates of Brookfield Property Partners L.P. In addition, our subsidiaries 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 Property Partners L.P. For the three and six-month periods ended June 30, 2021, revenues of $2 million and $4 million were generated, respectively (2020: $5 million and $7 million) and expenses of less than $1 million were incurred (2020: $2 million and $3 million). In addition, subsidiaries of Brookfield Infrastructure reported right-of-use assets and liabilities with Brookfield Property Partners L.P. of $12 million (December 31, 2020: $12 million).
Brookfield Infrastructure’s U.K. port operation provides port marine services on market terms to a subsidiary of Brookfield Business Partners L.P. For the three and six-month periods ended June 30, 2021, revenues of $1 million and $2 million, respectively, were generated (2020: $1 million and $2 million).
OFF-BALANCE SHEET ARRANGEMENTS
We do not have any off-balance sheet arrangements that have or are reasonably likely to have a material current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.
We, on behalf of our subsidiaries, provide letters of credit, which include, but are not limited to, guarantees for debt service reserves, capital reserves, construction completion and performance. As at June 30, 2021, letters of credit issued on behalf of our subsidiaries amounted to $64 million (December 31, 2020: $63 million).
In the normal course of operations, we execute agreements that provide for indemnification and guarantees to third parties in transactions such as business dispositions and acquisitions, construction projects, capital projects, and sales and purchases of assets and services. We have also agreed to indemnify our directors and certain of our officers and employees. The nature of substantially all of the indemnification undertakings prevents us from making a reasonable estimate of the maximum potential amount that we could be required to pay third parties, as many of the agreements do not specify a maximum amount and the amounts are dependent upon the outcome of future contingent events, the nature and likelihood of which cannot be determined at this time. Historically, we have made no significant payments under such indemnification agreements.
RECONCILIATION OF NON-IFRS FINANCIAL MEASURES
We focus on FFO to measure operating performance, along with IFRS measures such as net income. In addition, we also assess AFFO, Adjusted EBITDA, Adjusted Earnings and Invested Capital.
Adjusted EBITDA, FFO, AFFO, Adjusted Earnings and Invested Capital are presented based on our proportionate share of results in operations accounted for using the consolidation and the equity method whereby we either control or exercise significant influence or joint control over the investment, respectively. Proportionate financial information is not, and is not intended to be, presented in accordance with IFRS. Under IFRS, we are not considered to control those entities that have not been consolidated and as such, have been presented as investments in associates or joint ventures in Note 10 of our partnership’s financial statements included herein. The presentation of the assets and liabilities and revenues and expenses do not represent our legal claim to such items, and the removal of financial statement amounts that are attributable to non-controlling interests does not extinguish our partnership’s legal claims or exposures to such items.
As a result, segment revenues, costs attributable to revenues, general and administrative costs, interest expense, other income, depreciation and amortization, deferred income taxes, breakage and transaction costs, and non-cash valuation gains or losses are reconciling items that will differ from results presented in accordance with IFRS as these reconciling items include our proportionate share of earnings from investments in associates attributable to each of the above-noted items, and exclude the proportionate share of earnings (losses) of consolidated investments not held by our partnership apportioned to each of the above-noted items.
Q2 2021 INTERIM REPORT 69

We provide proportionate financial results because we believe it assists investors and analysts in estimating our overall performance and understanding our partnership’s share of results from its underlying investments which have varying economic ownership interests and financial statement presentations when determined in accordance with IFRS. We believe our proportionate financial information, when read in conjunction with our partnership’s reported results under IFRS, provides the most meaningful assessment of how our operations are performing and capital is being managed. The presentation of proportionate results has limitations as an analytical tool, including the following:
•The amounts shown on the individual line items were derived by applying our overall economic ownership interest percentage determined when applying the equity method of accounting and do not necessarily represent our legal claim to the assets and liabilities, or the revenues and expenses;
•Other companies may calculate proportionate results differently than we do.
Proportionate debt is presented based on our proportionate share of borrowing obligations relating to our investments in various portfolio businesses. Proportionate net debt is proportionate debt net of our proportionate share of cash. The proportionate financial information is not, and is not intended to be, presented in accordance with IFRS. We provide proportionate debt and net debt measures because we believe it assists investors and analysts in estimating our overall performance and understanding the leverage pertaining specifically to our partnership’s share of its invested capital in a given investment. When used in conjunction with Adjusted EBITDA, proportionate debt is expected to provide useful information as to how our partnership has financed its businesses at the asset-level. We believe our proportionate presentation, when read in conjunction with our partnership’s reported results under IFRS, including consolidated debt, provides a more meaningful assessment of how our operations are performing and capital is being managed. The presentation of proportionate debt has limitations as an analytical tool, including the following:
•Proportionate debt amounts do not represent our consolidated obligation for debt underlying a consolidated investment. If an individual project does not generate sufficient cash flows to service the entire amount of its debt payments, our company may determine, in our discretion, to pay the shortfall through an equity injection to avoid defaulting on the obligation. Such a shortfall may not be apparent from or may not equal the difference between aggregate proportionate Adjusted EBITDA for all of our portfolio investments and aggregate proportionate debt for all of our portfolio investments; and
•Other companies may calculate proportionate debt differently than we do.
Because of these limitations, our proportionate financial information should not be considered in isolation or as a substitute for our financial statements as reported under IFRS.
The following tables present each segment’s results in the format that management organizes its segments to make operating decisions and assess performance. These tables reconcile our proportionate results to our partnership’s consolidated statements of operating results on a line by line basis by aggregating the components comprising the earnings from our investments in associates and reflecting the portion of each line item attributable to non-controlling interests.
Refer to the “Discussion of Segment Reconciling Items” section of this MD&A for a reconciliation of segment results to our statement of operating results in accordance with IFRS along with a break-down of each of the reconciling items by type and by operating segment.
Net income is the most directly comparable IFRS measure to FFO, AFFO, Adjusted EBITDA and Adjusted Earnings. Partnership capital is the most directly comparable IFRS measure to Invested Capital. We urge investors to review the IFRS financial measures within the MD&A and to not rely on any single financial measure to evaluate our partnership.
We define FFO as net income excluding the impact of depreciation and amortization, deferred income taxes, breakage and transaction costs, and non-cash valuation gains or losses.
FFO has limitations as an analytical tool:
•FFO does not include depreciation and amortization expense; because we own capital assets with finite lives, depreciation and amortization expense recognizes the fact that we must maintain or replace our asset base in order to preserve our revenue generating capability;
•FFO does not include deferred income taxes, which may become payable if we own our assets for a long period of time; and
•FFO does not include certain non-recurring charges such as breakage and transaction costs or non-cash valuation gains, losses and impairment charges.
70 BROOKFIELD INFRASTRUCTURE PARTNERS L.P.

FFO is a measure of operating performance that is not calculated in accordance with and does not have any standardized meaning prescribed by IFRS as issued by the IASB. FFO is therefore unlikely to be comparable to similar measures presented by other issuers. FFO has limitations as an analytical tool. Specifically, our definition of FFO may differ from the definition used by other organizations, as well as the definition of Funds from Operations used by the REALPAC and the NAREIT, in part because the NAREIT definition is based on U.S. GAAP, as opposed to IFRS.
FFO is a key measure that we use to evaluate the performance of our operations and forms the basis for our partnership’s distribution policy.
We believe that FFO, when viewed in conjunction with our IFRS results, provides a more complete understanding of factors and trends affecting our underlying operations. FFO allows us to evaluate our businesses on the basis of cash return on invested capital by removing the effect of non-cash and other items.
We add back depreciation and amortization to remove the implication that our assets decline in value over time since we believe that the value of most of our assets will be sustained over time, provided we make all necessary maintenance expenditures. Specifically, in our financial statements we use the revaluation approach in accordance with IAS 16, Property, Plant and Equipment, whereby depreciation expense is determined based on a revalued amount, thereby reducing comparability with our peers who do not report under IFRS as issued by the IASB or who do not employ the revaluation approach to measuring property, plant and equipment. We add back deferred income taxes because we do not believe this item reflects the present value of the actual cash tax obligations we will be required to pay, particularly if our operations are held for a long period of time. We add back non-cash valuation gains or losses recorded in net income as they are non-cash and indicate a point-in-time approximation of value on items we consider long term. We also add back breakage and transaction costs as they are capital in nature.
In addition, we focus on AFFO, which is defined as FFO less capital expenditures required to maintain the current performance of our operations (maintenance capital expenditures). While FFO provides a basis for assessing current operating performance, it does not take into consideration the cost to sustain the operating performance of our partnership’s asset base. In order to assess the long-term, sustainable operating performance of our businesses, we observe that in addition to FFO, investors use AFFO by taking into account the impact of maintenance capital expenditures. AFFO is a measure of operating performance that is not calculated in accordance with, and does not have any standardized meaning prescribed by IFRS as issued by the IASB. AFFO is therefore unlikely to be comparable to similar measures presented by other issuers and has limitations as an analytical tool.
We also focus on Adjusted EBITDA which we define as net income excluding the impact of depreciation and amortization, interest expense, current and deferred income taxes, breakage and transaction costs and non-cash valuation gains or losses. Adjusted EBITDA provides a supplemental understanding of the performance of our business and enhanced comparability across periods and relative to our peers. Adjusted EBITDA excludes the impact of interest expense and current income taxes to remove the effect of the current capital structure and tax profile in assessing the operating performance of our businesses. Adjusted EBITDA is a measure of operating performance that is not calculated in accordance with, and does not have any standardized meaning prescribed by IFRS as issued by the IASB. Adjusted EBITDA is therefore unlikely to be comparable to similar measures presented by other issuers. Adjusted EBITDA has limitations as an analytical tool.
Adjusted Earnings is a measure that can be used to evaluate the performance of our operations, defined as net income attributable to our partnership, excluding any incremental depreciation and amortization expense associated with the revaluation of our property, plant and equipment and the impact of purchase price accounting, mark-to-market on hedging items and disposition gains or losses. While we believe that maintenance capital expenditures are the best measure of the cost to preserve our revenue generating capability, we acknowledge that investors may view historical depreciation as a more relevant proxy. Adjusted Earnings also excludes mark-to-market on hedging items recorded in net income or disposition gains or losses as we believe these items are not reflective of the ongoing performance of our underlying operations.
When viewed with our IFRS results, we believe that Adjusted Earnings provides a supplemental understanding of the performance of our underlying operations and also gives users enhanced comparability of our ongoing performance relative to peers in certain jurisdictions and across periods.
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 define Invested Capital as partnership capital removing the following items: non-controlling interest - in operating subsidiaries, retained earnings or deficit, accumulated other comprehensive income and ownership changes. We measure return on Invested Capital as AFFO, less estimated returns of capital on operations that are not perpetual in life, divided by the weighted average Invested Capital for the period.

1.Please see “Reconciliation of Operating Segment Measures” for a detailed reconciliation of Brookfield Infrastructure’s proportionate results to our partnership’s Consolidated Statements of Operating Results.
2.These adjustments have the combined effect of excluding the impact of depreciation and amortization, deferred income taxes, breakage and transaction costs, and non-cash valuation gains or losses recorded within our investments in associates and joint ventures in accordance with our definition of FFO.
3.By adjusting FFO attributable to non-controlling interests, the partnership is able to remove the portion of FFO earned at non-wholly owned subsidiaries that is not attributable to the partnership. We believe our proportionate financial information, when read in conjunction with the partnership’s reported results under IFRS, provides the most meaningful assessment of how our operations are performing. Please refer to the discussion of limitations of the proportional results as an analytical tool within the “Reconciliation of Non-IFRS Financial Measures” section of this MD&A.
All reconciling amounts from net income to FFO presented above are taken directly from the partnership’s consolidated financial statements, and in the case of “Contribution from investments in associates and joint ventures” and “Attributable to non-controlling interests”, the partnership’s proportionate share of FFO relating thereto are derived using the accounting policies consistent with those applied in the partnership’s consolidated financial statements. FFO for these items is calculated on the same basis as consolidated entities, as disclosed above, and is calculated by applying the same ownership percentages used in calculating the partnership’s share of equity accounted income and the corresponding elimination of non-controlling interests in accordance with IAS 28, Investments in Associates and Joint Ventures and IFRS 10, Consolidated Financial Statements, respectively.
For the three and six-month periods ended June 30, 2021, the difference between net income and FFO is predominantly due to depreciation and amortization, FFO contribution from investments in associates and joint ventures, FFO attributable to non-controlling interests, deferred tax expense and mark-to-market on hedging items and other. Depreciation and amortization increased from the prior year due to incremental charges from recently completed acquisitions, higher asset values following our annual revaluation process and capital expenditures made during the year. FFO attributable to non-controlling interests increased from the prior year predominantly due to acquisitions completed during the past year and organic growth. FFO contribution from investments in associates and joint ventures increased from the prior year as a result of the acquisition of our U.S. LNG export facility and the partial disposition of our Australian export terminal which resulted in a change in the basis of presentation from consolidation to the equity method. Deferred tax expense increased due to an increase in the future U.K. tax rate from 19% to 25%. Mark-to-market on hedging items and other primarily includes gains from the disposition of our Canadian district energy operation and smart meter portfolio.
The difference between net income and AFFO is due to the aforementioned items, in addition to maintenance capital expenditures of $84 million and $136 million for the three and six-month periods ended June 30, 2021 (2020: $68 million and $125 million).

We measure return on Invested Capital as AFFO less estimated returns of capital on operations that are not perpetual in life, divided by the weighted average Invested Capital for the period.
AFFO is defined as FFO less maintenance capital expenditures. AFFO for the three and six-month periods ended June 30, 2021 were $310 million and $689 million, respectively (2020: $265 million and $566 million). Estimated returns of capital for the three and six-month periods ended June 30, 2021 were $39 million and $78 million, respectively (2020: $30 million and $61 million).
Our partnership has met its investment return objectives for the three and six-month periods ended June 30, 2021 with returns on Invested Capital of 12% and 13%, respectively (2020: 10% and 11%).
Q2 2021 INTERIM REPORT 75

Reconciliation of Operating Segment Measures
Adjusted EBITDA, FFO and AFFO are presented based on our proportionate share of results in operations accounted for using consolidation and the equity method whereby we either control or exercise significant influence over the investment, respectively, in order to demonstrate the impact of key value drivers of each of these operating segments on our overall performance. As a result, segment depreciation and amortization, deferred income taxes, breakage and transaction costs, and non-cash valuation gains or losses are reconciling items that will differ from results presented in accordance with IFRS as these reconciling items (1) include our proportionate share of earnings from investments in associates and joint ventures attributable to each of the above-noted items, and (2) exclude the proportionate share of earnings (loss) of consolidated investments not held by us apportioned to each of the above-noted items.
The following tables present each segment’s results in the format that management organizes its segments to make operating decisions and assess performance. Each segment is presented on a proportionate basis, taking into account our ownership in operations accounted for using the consolidation and equity method whereby we either control or exercise significant influence over the investment, respectively. These tables reconcile our proportionate results to our partnership’s consolidated statements of operating results on a line by line basis by aggregating the components comprising the earnings from our investments in associates and reflecting the portion of each line item attributable to non-controlling interests. Refer to the “Discussion of Segment Reconciling Items” section of this MD&A for a reconciliation of segment results to our statement of operating results in accordance with IFRS.

The following tables provide each segment’s assets in the format that management organizes its segments to make operating decisions and assess performance. Each segment is presented on a proportionate basis, taking into account our ownership in operations using consolidation and the equity method whereby we either control or exercise significant influence over the investment respectively. These tables reconcile our proportionate assets to total assets presented on our Consolidated Statements of Financial Position by removing net liabilities contained within investments in associates, reflecting the assets attributable to non-controlling interests, and adjusting for working capital assets which are netted against working capital liabilities.

78 BROOKFIELD INFRASTRUCTURE PARTNERS L.P.

During the three and six-month periods ended June 30, 2021, contributions from investments in associates and joint ventures increased as compared to the same period in 2020. The increase is primarily attributable to the acquisition of our U.S. LNG export terminal and the partial disposition and deconsolidation of our Australian export terminal in December 2020.
During the three and six-month periods ended June 30, 2021, attribution to non-controlling interest increased as compared to the same period in 2020. The increase is primarily attributable to acquisitions completed over the past 12 months.
Critical Accounting Policies and Estimates
The preparation of financial statements requires management to make critical 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.
Critical judgments made by management and utilized in the normal course of preparing Brookfield Infrastructure’s consolidated financial statements are outlined below.
Revaluation of property, plant and equipment
Property, plant and equipment is revalued on a regular basis. The critical estimates and assumptions underlying the valuation of property, plant and equipment are set out in Note 13, Property, Plant and Equipment in our December 31, 2020 audited consolidated financial statements. Our partnership’s property, plant, and equipment are measured at fair value on a recurring basis with an effective date of revaluation for all asset classes as of December 31, 2020. Brookfield Infrastructure determines fair value under both the income and cost methods with due consideration to significant inputs such as the discount rate, terminal value multiple, overall investment horizon, useful life and replacement cost.
Impairment of goodwill, intangibles with indefinite lives and investment in associates and joint ventures
Our partnership assesses the impairment of goodwill and intangible assets with indefinite lives by reviewing the value-in-use or fair value less costs of disposal of the 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 unit; discount rates; terminal capitalization rates; terminal valuation dates; useful lives and residual values.
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.
CONTROLS AND PROCEDURES
No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the fiscal quarter ended June 30, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. We have not experienced any material impact to our internal controls over financial reporting due to the global pandemic. We are continually monitoring and assessing our internal controls to minimize the impact on their design and operating effectiveness.
Excluded from our evaluation were internal controls over financial reporting at our individually insignificant businesses acquired since January 1, 2021. The financial statements of these entities constitute approximately 1% of total assets, 2% of partnership capital and less than 1% of revenue and net income of the consolidated financial statements of our partnership as of and for the six-month period ended June 30, 2021.
Q2 2021 INTERIM REPORT 79

Risks Associated with the Global Pandemic
The rapid spread of the COVID-19 virus, which was declared by the World Health Organization to be a pandemic on March 11, 2020, and actions taken globally in response to COVID-19, have significantly disrupted international business activities.
Our business relies, to a certain extent, on free movement of goods, services, and capital from around the world, which has been significantly restricted as a result of COVID-19. To date, the impact on our partnership’s results has been substantially insulated by the contractual and regulated revenue frameworks of our business. While safeguarding the well-being of individuals is our paramount concern, we have implemented several measures designed to ensure continued operation at each of our businesses. Our partnership continues to monitor developments related to COVID-19, including the impact on global and local economies in the jurisdictions where we operate.
Given the ongoing and dynamic nature of the circumstances surrounding COVID-19, it is difficult to predict how significant the medium to long-term impacts of COVID-19, including any responses to it, will be on the global economy and our businesses or for how long any disruptions are likely to continue. The extent of such impacts will depend on future developments, which are highly uncertain, continuously evolving, and difficult to predict. Such developments could have an adverse effect on our assets, liabilities, business, financial condition, results of operations and cash flow. See “Cautionary statement regarding forward-looking statements”.
CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
This Management’s Discussion and Analysis contains forward-looking information and forward-looking statements within the meaning of applicable securities laws. We may make such statements in this report, in other filings with Canadian regulators or the SEC and in other public communications. The words “tend”, “seek”, “target”, “foresee”, “believe,” “expect,” “could”, “aim to,” “intend,” “objective”, “outlook”, “endeavour”, “estimate”, “likely”, “continue”, “plan”, derivatives thereof and other expressions of similar import, or the negative variations thereof, and similar expressions of future or conditional verbs such as “will”, “may”, “should,” which are predictions of or indicate future events, trends or prospects and which do not relate to historical matters, identify forward-looking statements. Forward-looking statements in this Management’s Discussion and Analysis include among others, statements with respect to our assets tending to appreciate in value over time, growth in our assets and operations, increases in FFO per unit and resulting capital appreciation, returns on capital and on equity, increasing demand for commodities and global movement of goods, expected capital expenditures, the impact of planned capital projects by customers of our businesses as on the performance and growth of those businesses, the extent of our corporate, general and administrative expenses, our ability to close acquisitions (including acquisitions referred to in this Management’s Discussion and Analysis and other planned transactions), our capacity to take advantage of opportunities in the marketplace, the future prospects of the assets that we operate or will operate, partnering with institutional investors, ability to identify, acquire and integrate new acquisition opportunities, long-term target return on our assets, sustainability of distribution levels, distribution growth and payout ratios, operating results and margins for our business and each operation, future prospects for the markets for our products, our plans for growth through internal growth and capital investments, ability to achieve stated objectives, ability to drive operating efficiencies, return on capital expectations for the business, contract prices and regulated rates for our operations, our expected future maintenance and capital expenditures, ability to deploy capital in accretive investments, impact on the business resulting from our view of future economic conditions, our ability to maintain sufficient financial liquidity, our ability to draw down funds under our bank credit facilities, our ability to secure financing through the issuance of equity or debt, expansions of existing operations, likely sources of future opportunities in the markets in which we operate, financing plans for our operating companies, foreign currency management activities and other statements with respect to our beliefs, outlooks, plans, expectations and intentions. Although we believe that the partnership’s anticipated future results, performance or achievements expressed or implied by the forward-looking statements and information are based upon reasonable assumptions and expectations, the reader should not place undue reliance on forward-looking statements and information because they involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the partnership to differ materially from anticipated future results, performance or achievements expressed or implied by such forward-looking statements and information.
80 BROOKFIELD INFRASTRUCTURE PARTNERS L.P.

Factors that could cause actual results to differ materially from those contemplated or implied by the forward-looking statements contained herein include general economic conditions in the jurisdictions in which we operate and elsewhere which may impact the markets for our products or services, the ability to achieve growth within Brookfield Infrastructure’s businesses, our ability to achieve the milestones necessary to deliver the targeted returns to our unitholders, which is uncertain, some of which depends on access to capital and continuing favourable commodity prices, the impact of market conditions on our businesses, including as a result of the COVID-19 outbreak, the fact that success of Brookfield Infrastructure is dependent on market demand for an infrastructure company, which is unknown, the availability of equity and debt financing for Brookfield Infrastructure, the ability to effectively complete new acquisitions in the competitive infrastructure space (including the potential acquisitions referred to in this letter to unitholders, some of which remain subject to the satisfaction of conditions precedent, and the inability to reach final agreement with counterparties to transactions referred to herein as being currently pursued, given that there can be no assurance that any such transaction will be agreed to or completed) and to integrate acquisitions into existing operations, changes in technology which have the potential to disrupt the businesses and industries in which we invest, the market conditions of key commodities, the price, supply or demand for which can have a significant impact upon the financial and operating performance of our business, regulatory decisions affecting our regulated businesses, our ability to secure favourable contracts, weather events affecting our business, traffic volumes on our toll road businesses, pandemics or epidemics, and other risks and factors described in the documents filed by us with the securities regulators in Canada and the United States, including under “Risk Factors” in our most recent Annual Report on Form 20-F and other risks and factors that are described therein. In addition, our future results may be impacted by risks associated with COVID-19, and the related global reduction in commerce and travel and substantial volatility in stock markets worldwide, which may result in a decrease of cash flows and impairment losses and/or revaluations on our investments and infrastructure assets, and we may be unable to achieve our expected returns.
We caution that the foregoing list of important factors that may affect future results is not exhaustive. When relying on our forward-looking statements to make decisions with respect to Brookfield Infrastructure, investors and others should carefully consider the foregoing factors and other uncertainties and potential events. Except as required by law, the partnership undertakes no obligation to publicly update or revise any forward-looking statements or information, whether written or oral, that may be as a result of new information, future events or otherwise.
