Corporate Information And Statement Of IFRS Compliance [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES (a) Basis of presentation These unaudited interim condensed consolidated financial statements of the partnership have been prepared in accordance with International Accounting Standard 34, Interim Financial Reporting , or IAS 34, as issued by the International Accounting Standards Board, or the IASB, and using the accounting policies the partnership applied in its annual consolidated financial statements as at and for the year ended December 31, 2018 , except for the impact of the adoption of the accounting standards described below. The accounting policies the partnership applied in its annual consolidated financial statements as at and for the year ended December 31, 2018 are disclosed in Note 2 of such consolidated financial statements, with which reference should be made in reading these unaudited interim condensed consolidated financial statements. All defined terms are also described in the annual consolidated financial statements. The unaudited interim condensed consolidated financial statements are prepared on a going concern basis and have been presented in U.S. dollars rounded to the nearest million unless otherwise indicated. The preparation of financial statements in accordance with IAS 34 requires the use of certain critical accounting estimates. It also requires management to exercise judgment in applying the accounting policies. The critical accounting estimates and judgments have been set out in Note 2 to the partnership's consolidated financial statements as at and for the year ended December 31, 2018 . There have been no significant changes to the method of determining significant estimates and judgments since December 31, 2018 , other than changes required as a result of adopting new standards as discussed below. These unaudited interim condensed consolidated financial statements were approved by the partnership's Board of Directors and authorized for issue on August 9, 2019 . (b) New accounting policies adopted The partnership has applied new and revised standards issued by the IASB that are effective for the period beginning on or after January 1, 2019. (i) Leases The partnership has applied IFRS 16, Leases ("IFRS 16") as of its effective date of January 1, 2019. The new standard brings most leases on the statement of financial position, eliminating the distinction between operating and finance leases. Lessor accounting, however, remains largely unchanged and the distinction between operating and finance leases is retained. IFRS 16 supersedes IAS 17, Leases and related interpretations and is effective for periods beginning on or after January 1, 2019. The transition impact is outlined in Note 2(c). The partnership assesses whether a contract is, or contains, a lease at inception of the contract and recognizes a right-of-use asset and a corresponding lease liability with respect to all lease arrangements in which it is a lessee, except for short-term leases (defined as leases with a lease term of 12 months or less) and leases of low value assets. For these leases, the partnership recognizes the lease payments as an operating expense on a straight-line basis over the term of the lease unless another systematic basis is more representative of the time pattern in which economic benefits from the leased assets are consumed. The lease liability is initially measured at the present value of the future lease payments, discounted using the interest rate implicit in the lease, if that rate can be determined, or otherwise the incremental borrowing rate. Lease payments included in the measurement of the lease liability comprise i) fixed lease payments, including in-substance fixed payments, less any lease incentives; ii) variable lease payments that depend on an index or rate, initially measured using the index or rate at the commencement date; iii) the amount expected to be payable by the lessee under residual value guarantees; iv) the exercise price of purchase options, if it is reasonably certain that the option will be exercised; and v) payments of penalties for terminating the lease, if the lease term reflects the exercise of an option to terminate the lease. The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the effective interest method) and by reducing the carrying amount to reflect the lease payments made. The partnership remeasures lease liabilities and makes a corresponding adjustment to the related right-of-use asset when i) the lease term has changed or there is a change in the assessment of exercise of a purchase option, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate; ii) the lease payments have changed due to changes in an index or rate or a change in expected payment under a guaranteed residual value, in which cases the lease liability is remeasured by discounting the revised lease payments using the initial discount rate (unless the lease payments change is due to a change in a floating interest rate, in which case a revised discount rate is used); or iii) a lease contract is modified and the lease modification is not accounted for as a separate lease, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate. The right-of-use asset comprises the initial measurement of the corresponding lease liability, lease payments made at or before the commencement date and any initial direct costs. The right-of-use asset is subsequently measured at cost less accumulated depreciation and impairment losses. It is depreciated over the shorter period of the lease term and useful life of the underlying asset. If a lease transfers ownership of the underlying asset or the cost of the right-of-use asset reflects that the partnership expects to exercise a purchase option, the related right-of-use asset is depreciated over the useful life of the underlying asset. The depreciation starts on the commencement date of the lease. The partnership applies IAS 36, Impairment of Assets, to determine whether a right-of-use asset is impaired and accounts for any identified impairment loss as described in the property plant and equipment policy. Variable rents that do not depend on an index or rate are not included in the measurement of the lease liability and the right-of-use asset. The related payments are recognized as an expense in the period in which the event or condition that triggers those payments occurs and are included in the line "direct operating costs" in the Consolidated Statement of Operations. The partnership has applied critical judgments in the application of IFRS 16, including: i) identifying whether a contract (or part of a contract) includes a lease; and ii) determining whether it is reasonably certain that lease extension or termination options will be exercised in determining lease terms. The partnership also uses critical estimates in the application of IFRS 16, including the estimation of lease term and determination of the appropriate rate to discount the lease payments. The partnership has elected to apply the following practical expedients in its application of the standard: • To recognize the payments associated with short-term and low value leases on a straight-line basis as an operating expense on a straight-line basis over the term of the lease unless another systematic basis is more representative of the time pattern in which economic benefits from the leased assets are consumed; and • To not allocate contract consideration between lease and non-lease components, but rather account for each lease and non-lease component as a single lease component, on a lease-by-lease basis. (ii) Uncertainty over Income Tax Treatments In June 2017, the IASB published IFRIC 23, Uncertainty over Income Tax Treatments ("IFRIC 23"), effective for annual periods beginning on or after January 1, 2019. The interpretation requires an entity to assess whether it is probable that a tax authority will accept an uncertain tax treatment used, or proposed to be used, by an entity in its income tax filings and to exercise judgment in determining whether each tax treatment should be considered independently or whether some tax treatments should be considered together. The decision should be based on which approach provides better predictions of the resolution of the uncertainty. An entity also has to consider whether it is probable that the relevant authority will accept each tax treatment, or group of tax treatments, assuming that the taxation authority with the right to examine any amounts reported to it will examine those amounts and will have full knowledge of all relevant information when doing so. On January 1, 2019, the partnership adopted IFRIC 23 on a modified retrospective basis. The adoption did not have a significant impact on the partnership's financial results. (iii) Business Combinations In October 2018, the IASB issued an amendment to IFRS 3, Business Combinations (“IFRS 3”), effective for annual periods beginning on or after January 1, 2020, with the option to early adopt beginning January 1, 2019. The amendment clarifies the definition of a business and assists entities in determining whether an acquisition is a business combination or an acquisition of a group of assets. The amendment emphasizes that to be considered a business, an acquired set of activities and assets must include an input and a substantive process that together significantly contribute to the ability to create outputs. The partnership adopted the IFRS 3 amendment on January 1, 2019 on a prospective basis and the adoption did not have an impact on the partnership’s consolidated financial statements. (c) Impact on adoption of new IFRS standards The partnership has adopted IFRS 16 using the modified retrospective method, whereby any transitional impact is recorded in equity as at January 1, 2019, and comparative periods are not restated. In applying IFRS 16 for the first time, the partnership has applied the following practical expedients permitted by the standard on a lease-by-lease basis. These practical expedients are only available upon adoption and cannot be applied for any new lease executed after adoption: • The accounting for operating leases with a remaining lease term of less than 12 months as of January 1, 2019 as short-term leases; • The application of a single discount rate to a portfolio of leases with reasonably similar characteristics; • The application of the policy choice option on adoption to measure the right-of-use assets at an amount equal to the lease liabilities, adjusted for any prepaid or accrued lease payments; • The reliance on our assessments of whether leases are onerous applied IAS 37, Provisions, Contingent Liabilities and Contingent Assets, immediately before January 1, 2019, instead of performing an impairment review; and • The use of hindsight in determining the lease term if the contract contains options to extend or terminate the lease. In addition, the partnership has applied the practical expedient available on transition to not reassess whether a contract meets the definition of a lease under IFRS 16 if the contract was, or was not, previously classified as a lease under IAS 17 Leases and IFRIC 4 Determining whether an Arrangement Contains a Lease prior to the adoption of IFRS 16. As at January 1, 2019, the adoption of IFRS 16 resulted in the recognition of lease liabilities that are recorded in accounts payable and other of $987 million and right-of-use assets that are classified as property, plant, and equipment of $978 million , adjusted for any prepaid or accrued lease payments (including any lease incentives). The adoption of IFRS 16 did not have any impact on equity. The weighted average incremental borrowing rate used in determining the lease liabilities on January 1, 2019 was approximately 4.3% . The difference between the operating lease commitments disclosed applying IAS 17 as at December 31, 2018 and the lease liabilities recognized as at January 1, 2019 is due to discounting using the incremental borrowing rate on January 1, 2019, and short-term and low value leases recognized on a straight-line basis as expense. When comparing results to prior periods, the adoption of IFRS 16 resulted in a reduction of direct operating costs by $60 million and $113 million , an increase to interest and depreciation expense of $13 million and $25 million , and $47 million and $88 million , respectively, for the three and six month period ended June 30, 2019 . In addition, under IFRS 16, lease payments are split between cash payments for the interest portion of the lease liability, which are classified as cash flows used in operating activities, and repayments of principal, which are classified as cash flows used in financing activities. In contrast under IAS 17, payments under operating leases were presented as part of cash flows used in operating activities.

ACQUISITION OF BUSINESSES

ACQUISITION OF BUSINESSES	6 Months Ended

Business Combinations 1 [Abstract]
ACQUISITION OF BUSINESSES	ACQUISITION OF BUSINESSES When determining the basis of accounting for the partnership’s investees, the partnership evaluates the degree of influence that the partnership exerts directly or through an arrangement over the investees' relevant activities. Control is obtained when the partnership has power over the acquired entities and an ability to use its power to affect the returns of these entities. The partnership accounts for business combinations using the acquisition method of accounting, pursuant to which the cost of acquiring a business is allocated to its identifiable tangible and intangible assets and liabilities on the basis of the estimated fair values at the date of acquisition. (a) Acquisitions completed in the six months ended June 30, 2019 The following summarizes the consideration transferred, assets acquired and liabilities assumed at the applicable acquisition dates for significant acquisitions. (US$ MILLIONS) Business Services Industrials Total (1) Cash $ 1,156 $ 3,764 $ 4,920 Total Consideration (2) $ 1,156 $ 3,764 $ 4,920 (US$ MILLIONS) Cash and cash equivalents $ 25 $ 11 $ 36 Accounts and other receivable, net 171 1,154 1,325 Inventory, net 41 1,784 1,825 Assets held for sale 6 — 6 Equity accounted investments 9 838 847 Property, plant and equipment 2,612 3,567 6,179 Intangible assets 264 6,420 6,684 Goodwill 1,450 1,736 3,186 Deferred income tax asset 93 346 439 Financial assets 10 27 37 Other assets — 358 358 Accounts payable and other (547 ) (1,898 ) (2,445 ) Deferred income tax liabilities (79 ) (1,122 ) (1,201 ) Net assets acquired before non-controlling interest 4,055 13,221 17,276 Non-controlling interest (3) (2,899 ) (9,457 ) (12,356 ) Net Assets Acquired $ 1,156 $ 3,764 $ 4,920 __________________________________ (1) The initial fair values of acquired assets, liabilities and goodwill for the acquisitions have been determined on a preliminary basis as at the dates of acquisition. (2) Excludes consideration attributable to non-controlling interest which represents the interest of others in operating subsidiaries. (3) Non-controlling interests recognized on business combination, were measured at fair value. Business Services Healthscope Limited ("Healthscope") On June 6, 2019, together with institutional partners, the partnership acquired Healthscope, an Australian based healthcare provider that operates private hospitals and provides pathology services. The partnership's economic interest of 28% was acquired for consideration of $1,156 million . The partnership has a 100% voting interest in this business, which provides us with control. Accordingly, the partnership consolidates this business for financial reporting purposes. Acquisition costs of approximately $22 million were recorded as other expense on the consolidated statements of operating results. Goodwill of $1,450 million was acquired, which represents the expected growth the partnership expects to receive from the integration of the operations. The goodwill recognized is no t deductible for income tax purposes. Intangible assets of $264 million were acquired, primarily comprised of customer contracts. The partnership’s results from operations for the period ended June 30, 2019 includes $36 million of revenue and $5 million of net loss attributable to the partnership from the acquisition. If this acquisition had been effective January 1, 2019, the partnership would have recorded revenue of $189 million and net loss of $21 million attributable to the partnership for the six months ended June 30, 2019. Industrials Clarios On April 30, 2019, together with institutional partners, the partnership acquired Clarios (formerly known as the “Power Solutions Business of Johnson Controls International plc”), a global producer and distributor of automotive batteries. The partnership's economic interest of 29% was acquired for consideration of $3,764 million . The partnership has a 100% voting interest in this business, which provides us with control. Accordingly, the partnership consolidates this business for financial reporting purposes. Acquisition costs of approximately $41 million were recorded as other expense on the consolidated statements of operating results. Goodwill of $1,736 million was acquired, which is largely reflective of the potential to innovate and grow the business. $20 million of the goodwill recognized is deductible for income tax purposes. Intangible assets of $6,420 million were acquired, primarily comprised of customer relationships, patented technology, and trademarks.

Fair Value Measurement [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair values are determined by reference to quoted bid or ask prices, as appropriate. Where bid and ask prices are unavailable, the closing price of the most recent transaction of that instrument is used. In the absence of an active market, fair values are determined based on prevailing market rates such as bid and ask prices, as appropriate for instruments with similar characteristics and risk profiles or internal or external valuation models, such as option pricing models and discounted cash flow analysis, 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, the partnership looks primarily to external readily observable market inputs such as interest rate yield curves, currency rates, and price and rate volatilities as applicable. Classification of Financial instruments classified as fair value through profit or loss are carried at fair value in the unaudited interim condensed consolidated statements of financial position and changes in fair values are recognized in profit or loss. The following table provides the details of financial instruments and their associated financial instrument classifications as at June 30, 2019 : (US$ MILLIONS) MEASUREMENT BASIS Fair Value through Profit and Loss Fair Value through Other Comprehensive Income Amortized Cost Total Financial assets Cash and cash equivalents $ — $ — $ 2,940 $ 2,940 Accounts and other receivable, net (current and non-current) (1) 62 — 5,826 5,888 Other assets (current and non-current) (2) — — 584 584 Financial assets (current and non-current) (3) 377 302 520 1,199 Total $ 439 $ 302 $ 9,870 $ 10,611 Financial liabilities Accounts payable and other (4) $ 384 $ 130 $ 10,418 $ 10,932 Borrowings (current and non-current) — — 22,516 22,516 Total $ 384 $ 130 $ 32,934 $ 33,448 ____________________________________ (1) Accounts receivable recognized at fair value relates to our mining business.

Financial Instruments [Abstract]
BORROWINGS	BORROWINGS (a) Corporate borrowings As at June 30, 2019 , the partnership has a revolving credit facility with Brookfield that permits borrowings of up to $500 million for the purpose of funding acquisitions and investments. The credit facility is available in U.S. or Canadian dollars, and advances are made by way of LIBOR, base rate, bankers’ acceptance rate or prime rate loans. The credit facility bears interest at the specified LIBOR or bankers’ acceptance rate plus 3.75% , or the specified base rate or prime rate plus 2.75% . As at June 30, 2019 , the credit facility remains undrawn. The partnership also has bilateral credit facilities with a diverse group of banks with aggregate borrowing capacity of $1,050 million . Advances under the facilities are available in Euros, Sterling, Australian, U.S. or Canadian dollars, and advances bear interest at the specified LIBOR, EURIBOR, CDOR, BBSY or bankers' acceptance rate plus 2.50% , or the specified base rate or prime rate plus 1.50% . The facilities are used for general corporate purposes and to fund acquisitions and investments. As at June 30, 2019, the credit facility remains undrawn. (b) Non-recourse subsidiary borrowings Total current and non-current borrowings as at June 30, 2019 were $22,516 million ( December 31, 2018 : $10,866 million ). The increase of $11,650 million compared to December 31, 2018 is primarily due to the acquisition of Healthscope and Clarios, partially offset by with debt repayments at GrafTech and the disposition of our facilities management business. Some of the partnership's businesses have credit facilities in which they borrow and repay on a monthly basis. This movement has been shown on a net basis in the partnership's unaudited interim condensed consolidated statements of cash flow. The partnership has credit facilities within its operating businesses with major financial institutions. The credit facilities are primarily composed of revolving term credit facilities and revolving operating facilities with variable interest rates. In certain cases, the facilities may have financial covenants which are generally in the form of interest coverage ratios and leverage ratios. One of the partnership's real estate services businesses within our business services segment has a securitization program under which it transfers an undivided co-ownership interest in eligible receivables on a fully serviced basis, for cash proceeds, at their fair value under the terms of the agreement. While the sale of the co-ownership interest is considered a legal sale, the partnership has determined that the asset derecognition criteria has not been met as substantially all risk and rewards of ownership are not transferred. Our operations are currently in compliance with or have obtained waivers related to all material covenant requirements of their term loans and credit facilities.

Operating Segments [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION Our operations are organized into four operating segments which are regularly reviewed by our Chief Operating Decision Maker (the "CODM") for the purpose of allocating resources to the segment and to assess its performance. The key measures used by the CODM in assessing performance and in making resource allocation decisions are company funds from operations, or Company FFO and Company EBITDA. Company FFO is calculated as net income excluding the impact of depreciation and amortization, deferred income taxes, breakage and transaction costs, non-cash gains or losses as appropriate, and other items. When determining Company FFO, we include our proportionate share of Company FFO of equity accounted investment. Company FFO is further adjusted as Company EBITDA to exclude the impact of realized disposition gains (losses), interest expenses, current income taxes, and realized disposition gains, current income taxes and interest expenses related to equity accounted investments.

SUBSEQUENT EVENTS	SUBSEQUENT EVENTS (a) Distribution On July 31, 2019, the Board of Directors declared a quarterly distribution in the amount of $0.0625 per unit, payable on September 30, 2019 to unitholders of record as at the close of business on August 30, 2019. (b) Exercise of underwriters' option On July 23, 2019 the underwriters for the public offering of the limited partnership units that closed on June 28, 2019 , purchased an additional 1,070,000 limited partnership units at a price of $39.40 per unit, pursuant to the exercise of the underwriter's over-allotment option. The partnership received additional gross proceeds of approximately $42 million from the over-allotment option before approximately $2 million in equity issuance costs. This resulted in a decrease in Brookfield's ownership of the partnership to 62.7% . (c) Acquisition of Ouro Verde Locação e Seviços S.A. ("Ouro Verde") On July 8, 2019 , together with institutional partners, the partnership acquired a 100% interest in Ouro Verde, a Brazilian fleet management company, for approximately $131 million . The partnership’s share is expected to be approximately $50 million which will be determined once institutional partner participation is finalized, and the partnership expects to consolidate this business for financial reporting purposes. Due to the recent closing of the acquisition, the complete valuation and initial purchase price accounting for the business combination is not available as at the date of release of these unaudited interim condensed consolidated financial statements. As a result, the partnership has not provided amounts recognized as at the acquisition date for major classes of assets acquired and liability assumed.

Corporate Information And Statement Of IFRS Compliance [Abstract]
Basis of presentation	Basis of presentation These unaudited interim condensed consolidated financial statements of the partnership have been prepared in accordance with International Accounting Standard 34, Interim Financial Reporting , or IAS 34, as issued by the International Accounting Standards Board, or the IASB, and using the accounting policies the partnership applied in its annual consolidated financial statements as at and for the year ended December 31, 2018 , except for the impact of the adoption of the accounting standards described below. The accounting policies the partnership applied in its annual consolidated financial statements as at and for the year ended December 31, 2018 are disclosed in Note 2 of such consolidated financial statements, with which reference should be made in reading these unaudited interim condensed consolidated financial statements. All defined terms are also described in the annual consolidated financial statements. The unaudited interim condensed consolidated financial statements are prepared on a going concern basis and have been presented in U.S. dollars rounded to the nearest million unless otherwise indicated. The preparation of financial statements in accordance with IAS 34 requires the use of certain critical accounting estimates. It also requires management to exercise judgment in applying the accounting policies. The critical accounting estimates and judgments have been set out in Note 2 to the partnership's consolidated financial statements as at and for the year ended December 31, 2018 . There have been no significant changes to the method of determining significant estimates and judgments since December 31, 2018 , other than changes required as a result of adopting new standards as discussed below. These unaudited interim condensed consolidated financial statements were approved by the partnership's Board of Directors and authorized for issue on August 9, 2019 .
New accounting policies adopted	New accounting policies adopted The partnership has applied new and revised standards issued by the IASB that are effective for the period beginning on or after January 1, 2019. (i) Leases The partnership has applied IFRS 16, Leases ("IFRS 16") as of its effective date of January 1, 2019. The new standard brings most leases on the statement of financial position, eliminating the distinction between operating and finance leases. Lessor accounting, however, remains largely unchanged and the distinction between operating and finance leases is retained. IFRS 16 supersedes IAS 17, Leases and related interpretations and is effective for periods beginning on or after January 1, 2019. The transition impact is outlined in Note 2(c). The partnership assesses whether a contract is, or contains, a lease at inception of the contract and recognizes a right-of-use asset and a corresponding lease liability with respect to all lease arrangements in which it is a lessee, except for short-term leases (defined as leases with a lease term of 12 months or less) and leases of low value assets. For these leases, the partnership recognizes the lease payments as an operating expense on a straight-line basis over the term of the lease unless another systematic basis is more representative of the time pattern in which economic benefits from the leased assets are consumed. The lease liability is initially measured at the present value of the future lease payments, discounted using the interest rate implicit in the lease, if that rate can be determined, or otherwise the incremental borrowing rate. Lease payments included in the measurement of the lease liability comprise i) fixed lease payments, including in-substance fixed payments, less any lease incentives; ii) variable lease payments that depend on an index or rate, initially measured using the index or rate at the commencement date; iii) the amount expected to be payable by the lessee under residual value guarantees; iv) the exercise price of purchase options, if it is reasonably certain that the option will be exercised; and v) payments of penalties for terminating the lease, if the lease term reflects the exercise of an option to terminate the lease. The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the effective interest method) and by reducing the carrying amount to reflect the lease payments made. The partnership remeasures lease liabilities and makes a corresponding adjustment to the related right-of-use asset when i) the lease term has changed or there is a change in the assessment of exercise of a purchase option, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate; ii) the lease payments have changed due to changes in an index or rate or a change in expected payment under a guaranteed residual value, in which cases the lease liability is remeasured by discounting the revised lease payments using the initial discount rate (unless the lease payments change is due to a change in a floating interest rate, in which case a revised discount rate is used); or iii) a lease contract is modified and the lease modification is not accounted for as a separate lease, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate. The right-of-use asset comprises the initial measurement of the corresponding lease liability, lease payments made at or before the commencement date and any initial direct costs. The right-of-use asset is subsequently measured at cost less accumulated depreciation and impairment losses. It is depreciated over the shorter period of the lease term and useful life of the underlying asset. If a lease transfers ownership of the underlying asset or the cost of the right-of-use asset reflects that the partnership expects to exercise a purchase option, the related right-of-use asset is depreciated over the useful life of the underlying asset. The depreciation starts on the commencement date of the lease. The partnership applies IAS 36, Impairment of Assets, to determine whether a right-of-use asset is impaired and accounts for any identified impairment loss as described in the property plant and equipment policy. Variable rents that do not depend on an index or rate are not included in the measurement of the lease liability and the right-of-use asset. The related payments are recognized as an expense in the period in which the event or condition that triggers those payments occurs and are included in the line "direct operating costs" in the Consolidated Statement of Operations. The partnership has applied critical judgments in the application of IFRS 16, including: i) identifying whether a contract (or part of a contract) includes a lease; and ii) determining whether it is reasonably certain that lease extension or termination options will be exercised in determining lease terms. The partnership also uses critical estimates in the application of IFRS 16, including the estimation of lease term and determination of the appropriate rate to discount the lease payments. The partnership has elected to apply the following practical expedients in its application of the standard: • To recognize the payments associated with short-term and low value leases on a straight-line basis as an operating expense on a straight-line basis over the term of the lease unless another systematic basis is more representative of the time pattern in which economic benefits from the leased assets are consumed; and • To not allocate contract consideration between lease and non-lease components, but rather account for each lease and non-lease component as a single lease component, on a lease-by-lease basis. (ii) Uncertainty over Income Tax Treatments In June 2017, the IASB published IFRIC 23, Uncertainty over Income Tax Treatments ("IFRIC 23"), effective for annual periods beginning on or after January 1, 2019. The interpretation requires an entity to assess whether it is probable that a tax authority will accept an uncertain tax treatment used, or proposed to be used, by an entity in its income tax filings and to exercise judgment in determining whether each tax treatment should be considered independently or whether some tax treatments should be considered together. The decision should be based on which approach provides better predictions of the resolution of the uncertainty. An entity also has to consider whether it is probable that the relevant authority will accept each tax treatment, or group of tax treatments, assuming that the taxation authority with the right to examine any amounts reported to it will examine those amounts and will have full knowledge of all relevant information when doing so. On January 1, 2019, the partnership adopted IFRIC 23 on a modified retrospective basis. The adoption did not have a significant impact on the partnership's financial results. (iii) Business Combinations In October 2018, the IASB issued an amendment to IFRS 3, Business Combinations (“IFRS 3”), effective for annual periods beginning on or after January 1, 2020, with the option to early adopt beginning January 1, 2019. The amendment clarifies the definition of a business and assists entities in determining whether an acquisition is a business combination or an acquisition of a group of assets. The amendment emphasizes that to be considered a business, an acquired set of activities and assets must include an input and a substantive process that together significantly contribute to the ability to create outputs. The partnership adopted the IFRS 3 amendment on January 1, 2019 on a prospective basis and the adoption did not have an impact on the partnership’s consolidated financial statements.
Impact on adoption of new IFRS standards	Impact on adoption of new IFRS standards The partnership has adopted IFRS 16 using the modified retrospective method, whereby any transitional impact is recorded in equity as at January 1, 2019, and comparative periods are not restated. In applying IFRS 16 for the first time, the partnership has applied the following practical expedients permitted by the standard on a lease-by-lease basis. These practical expedients are only available upon adoption and cannot be applied for any new lease executed after adoption: • The accounting for operating leases with a remaining lease term of less than 12 months as of January 1, 2019 as short-term leases; • The application of a single discount rate to a portfolio of leases with reasonably similar characteristics; • The application of the policy choice option on adoption to measure the right-of-use assets at an amount equal to the lease liabilities, adjusted for any prepaid or accrued lease payments; • The reliance on our assessments of whether leases are onerous applied IAS 37, Provisions, Contingent Liabilities and Contingent Assets, immediately before January 1, 2019, instead of performing an impairment review; and • The use of hindsight in determining the lease term if the contract contains options to extend or terminate the lease. In addition, the partnership has applied the practical expedient available on transition to not reassess whether a contract meets the definition of a lease under IFRS 16 if the contract was, or was not, previously classified as a lease under IAS 17 Leases and IFRIC 4 Determining whether an Arrangement Contains a Lease prior to the adoption of IFRS 16. As at January 1, 2019, the adoption of IFRS 16 resulted in the recognition of lease liabilities that are recorded in accounts payable and other of $987 million and right-of-use assets that are classified as property, plant, and equipment of $978 million , adjusted for any prepaid or accrued lease payments (including any lease incentives). The adoption of IFRS 16 did not have any impact on equity. The weighted average incremental borrowing rate used in determining the lease liabilities on January 1, 2019 was approximately 4.3% . The difference between the operating lease commitments disclosed applying IAS 17 as at December 31, 2018 and the lease liabilities recognized as at January 1, 2019 is due to discounting using the incremental borrowing rate on January 1, 2019, and short-term and low value leases recognized on a straight-line basis as expense. When comparing results to prior periods, the adoption of IFRS 16 resulted in a reduction of direct operating costs by $60 million and $113 million , an increase to interest and depreciation expense of $13 million and $25 million , and $47 million and $88 million , respectively, for the three and six month period ended June 30, 2019 . In addition, under IFRS 16, lease payments are split between cash payments for the interest portion of the lease liability, which are classified as cash flows used in operating activities, and repayments of principal, which are classified as cash flows used in financing activities. In contrast under IAS 17, payments under operating leases were presented as part of cash flows used in operating activities.
Leases	Leases The partnership has applied IFRS 16, Leases ("IFRS 16") as of its effective date of January 1, 2019. The new standard brings most leases on the statement of financial position, eliminating the distinction between operating and finance leases. Lessor accounting, however, remains largely unchanged and the distinction between operating and finance leases is retained. IFRS 16 supersedes IAS 17, Leases and related interpretations and is effective for periods beginning on or after January 1, 2019. The transition impact is outlined in Note 2(c). The partnership assesses whether a contract is, or contains, a lease at inception of the contract and recognizes a right-of-use asset and a corresponding lease liability with respect to all lease arrangements in which it is a lessee, except for short-term leases (defined as leases with a lease term of 12 months or less) and leases of low value assets. For these leases, the partnership recognizes the lease payments as an operating expense on a straight-line basis over the term of the lease unless another systematic basis is more representative of the time pattern in which economic benefits from the leased assets are consumed. The lease liability is initially measured at the present value of the future lease payments, discounted using the interest rate implicit in the lease, if that rate can be determined, or otherwise the incremental borrowing rate. Lease payments included in the measurement of the lease liability comprise i) fixed lease payments, including in-substance fixed payments, less any lease incentives; ii) variable lease payments that depend on an index or rate, initially measured using the index or rate at the commencement date; iii) the amount expected to be payable by the lessee under residual value guarantees; iv) the exercise price of purchase options, if it is reasonably certain that the option will be exercised; and v) payments of penalties for terminating the lease, if the lease term reflects the exercise of an option to terminate the lease. The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the effective interest method) and by reducing the carrying amount to reflect the lease payments made. The partnership remeasures lease liabilities and makes a corresponding adjustment to the related right-of-use asset when i) the lease term has changed or there is a change in the assessment of exercise of a purchase option, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate; ii) the lease payments have changed due to changes in an index or rate or a change in expected payment under a guaranteed residual value, in which cases the lease liability is remeasured by discounting the revised lease payments using the initial discount rate (unless the lease payments change is due to a change in a floating interest rate, in which case a revised discount rate is used); or iii) a lease contract is modified and the lease modification is not accounted for as a separate lease, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate. The right-of-use asset comprises the initial measurement of the corresponding lease liability, lease payments made at or before the commencement date and any initial direct costs. The right-of-use asset is subsequently measured at cost less accumulated depreciation and impairment losses. It is depreciated over the shorter period of the lease term and useful life of the underlying asset. If a lease transfers ownership of the underlying asset or the cost of the right-of-use asset reflects that the partnership expects to exercise a purchase option, the related right-of-use asset is depreciated over the useful life of the underlying asset. The depreciation starts on the commencement date of the lease. The partnership applies IAS 36, Impairment of Assets, to determine whether a right-of-use asset is impaired and accounts for any identified impairment loss as described in the property plant and equipment policy. Variable rents that do not depend on an index or rate are not included in the measurement of the lease liability and the right-of-use asset. The related payments are recognized as an expense in the period in which the event or condition that triggers those payments occurs and are included in the line "direct operating costs" in the Consolidated Statement of Operations. The partnership has applied critical judgments in the application of IFRS 16, including: i) identifying whether a contract (or part of a contract) includes a lease; and ii) determining whether it is reasonably certain that lease extension or termination options will be exercised in determining lease terms. The partnership also uses critical estimates in the application of IFRS 16, including the estimation of lease term and determination of the appropriate rate to discount the lease payments. The partnership has elected to apply the following practical expedients in its application of the standard: • To recognize the payments associated with short-term and low value leases on a straight-line basis as an operating expense on a straight-line basis over the term of the lease unless another systematic basis is more representative of the time pattern in which economic benefits from the leased assets are consumed; and • To not allocate contract consideration between lease and non-lease components, but rather account for each lease and non-lease component as a single lease component, on a lease-by-lease basis.
