Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation As used in these condensed consolidated financial statements and related notes, unless the context requires otherwise, the terms “Brookfield DTLA,” the “Company,” “us,” “we” and “our” refer to Brookfield DTLA Fund Office Trust Investor Inc. Principles of Consolidation and Basis of Presentation The accompanying unaudited condensed consolidated financial statements and related disclosures have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) applicable to interim financial information and with the instructions to Form 10‑Q and Rule 10-01 of Regulation S-X. In the opinion of management, all adjustments, consisting of only those of a normal and recurring nature, considered necessary for a fair presentation of the financial position and interim results of Brookfield DTLA as of and for the periods presented have been included. The results of operations for interim periods are not necessarily indicative of those that may be expected for a full fiscal year. The condensed consolidated balance sheet data as of December 31, 2017 has been derived from Brookfield DTLA’s audited financial statements; however, the accompanying notes to the condensed consolidated financial statements do not include all disclosures required by GAAP. The financial information included herein should be read in conjunction with the consolidated financial statements and related notes included in Brookfield DTLA’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 27, 2018 . Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. For example, estimates and assumptions have been made with respect to fair values of assets and liabilities for purposes of applying the acquisition method of accounting, the useful lives of assets, recoverable amounts of receivables, impairment of long-lived assets and fair value of debt. Actual results could ultimately differ from such estimates. Accounting Pronouncements Adopted in 2018 Effective January 1, 2018, Brookfield DTLA adopted the guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2016-18, Restricted Cash to Accounting Standards Codification (“ASC”) Topic 230, Statement of Cash Flows. ASU 2016-18 requires entities to show the change during the period in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the statement of cash flows. We adopted ASU 2016-18 on a retrospective basis. Therefore, amounts generally described as restricted cash and restricted cash equivalents are included with cash and cash equivalents when reconciling the beginning of period and end of period total amounts shown in the Company’s condensed consolidated statements of cash flows for the six months ended June 30, 2018 and 2017 . As a result of the adoption of ASU 2016-18, the change in restricted cash is no longer presented as a separate line item within cash flows from investing activities in the condensed consolidated statement of cash flows since such balances are now included in total cash at both the beginning and end of the reporting period. As a result, for the six months ended June 30, 2017 the Company used net cash in investing activities of $26.5 million instead of $14.7 million as previously reported. Effective January 1, 2018, Brook field DTLA adopted, on a modified retrospective basis, the guidance in ASU 2014-09, Revenue from Contracts with Customers (ASC Topic 606). ASU 2014-09, as amended by subsequent ASUs on the topic, establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most of the existing revenue recognition guidance. ASU 2014-09 requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration that the entity expects to be entitled to receive in exchange for those goods or services and also requires certain additional disclosures. The adoption of this pronouncement did not have an impact on Brookfield DTLA’s condensed consolidated financial statements . Effective January 1, 2018, Broo kfield DTLA adopted, on a retrospective basis, the guidance in ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments to ASC Topic 230, Statement of Cash Flows . ASU 2016-15 clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The adoption of this guidance did not have an impact on Brookfield DTLA’s condensed consolidated financial statements . Effective January 1, 2018, Bro okfield DTLA adopted, on a prospective basis, the guidance in ASU 2017-01, Clarifying the Definition of a Business to ASC Topic 805, Business Combinations. ASU 2017-01 introduced amendments that are intended to make the guidance on the definition of a business more consistent and cost-efficient. The objective of the update is to add further guidance that assists entities in evaluating whether a transaction should be accounted for as an acquisition (or disposal) of assets or as a business by providing a basis to determine when a set of assets and activities acquired is not a business. We expect that future acquisitions of operating and development properties, if any, will be accounted for as asset acquisitions under the new guidance, instead of as business combinations under the previous guidance. Additionally, we expect that most of the transaction costs associated with any future acquisitions will be capitalized in the consolidated balance sheet as part of the purchase price of the property acquired instead of being expensed as incurred in the consolidated statement of operations as part of acquisition-related expenses. Effective January 1, 2018, Brookfield DTLA adopted, on a retrospective basis, the guidance in ASU 2017-05, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets to ASC Subtopic 610-20, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets . ASU 2017-05 clarifies the scope of recently established guidance on nonfinancial asset derecognition as well as the accounting for partial sales of nonfinancial assets. This update conforms the derecognition guidance on nonfinancial assets with the model for transactions in ASC 606. The adoption of this guidance did not have an impact on Brookfield DTLA’s condensed consolidated financial statements . Accounting Pronouncements Effective January 1, 2019 Leases In February 2016, the FASB issued an update (“ASU 2016-02”) to ASC Topic 842, Leases, to amend the accounting guidance for leases. ASU 2016-02 sets out the principles for the recognition, measurement, presentation, and disclosure of leases for both lessees and lessors. The guidance requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on a principle of whether or not the lease is effectively a financed purchase. For all leases with a term greater than 12 months, lessees are required to record a right-of-use asset representing its right to use the underlying asset for the lease term and a liability to make lease payments on its balance sheet and will recognize lease expense generally on a straight‑line basis over the lease term in its statement of operations. For leases with a term of 12 months or less, lessees are permitted to make an accounting policy election by class of underlying asset not to recognize lease assets or liabilities on its balance sheet. If a lessee makes this election, it will recognize lease expense for such leases using the effective interest method. We are currently evaluating the impact of the adoption of ASU 2016-02 on Brookfield DTLA’s consolidated financial statements, and we currently believe that the adoption of this standard will not significantly change the accounting for operating leases on Brookfield DTLA’s consolidated balance sheet where we are the lessor, and that such leases will be accounted for in a similar manner. Under ASU 2016 ‑ 02, initial direct costs for both lessees and lessors will include only those costs that are incremental to the arrangement and would not have been incurred if the lease had not been obtained. As a result, Brookfield DTLA may no longer be able to capitalize internal leasing costs and instead may be required to expense these costs as incurred. ASU 2016-02 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2018, with early adoption permitted. In January 2018, the FASB released an exposure draft to amend ASU 2016-02 that would (1) simplify transition requirements for both lessees and lessors by adding an option that would permit an organization to apply the transition provisions of the new standard at its adoption date instead of at the earliest comparative period presented in its financial statements and (2) provide a practical expedient for lessors that would permit lessors to make an accounting election to not separate nonlease components from the associated lease components if certain criteria are met. In March 2018, the FASB finalized the changes with respect to optional transition relief and approved a practical expedient for lessors that would permit lessors to make an accounting policy election to not separate nonlease components from the associated lease components, by class of underlying asset, if the following two criteria are met: (1) the timing and pattern of transfer of the lease and nonlease components are the same and (2) the lease component would be classified as an operating lease if accounted for separately. For leases where we are the lessor, we currently believe that we will elect the optional transition relief and that we will meet the noted criteria to not be required to bifurcate and separately report nonlease components, such as common area maintenance revenue, for operating leases in our consolidated statement of operations. As a result, we currently believe that leases where we are the lessor will be accounted for in a similar method to existing standards with the underlying leased asset being reported and recognized as a real estate asset. The FASB is expected to issue an ASU codifying these changes. We currently expect to adopt this standard effective January 1, 2019 using the practical expedients proposed in the standard and the changes approved by the FASB. Other In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities to ASC Topic 815, Derivatives and Hedging . ASU 2017-12 introduced amendments intended to make targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. The objective of the update is to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. ASU 2017-12 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2018, with early adoption permitted, including adoption in an interim period. All transition requirements and elections should be applied to hedging relationships existing as of the date of adoption and the effect of the adoption should be reflected as of the beginning of the fiscal year of adoption. We are currently evaluating the impact of the adoption of this guidance on Brookfield DTLA’s consolidated financial statements. Accounting Pronouncements Effective January 1, 2020 In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, to amend the accounting for credit losses for certain financial instruments. Under the new guidance, an entity recognizes its estimate of expected credit losses as an allowance, which the FASB believes will result in more timely recognition of such losses. ASU 2016-13 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2019, with early adoption permitted as of the fiscal year beginning after December 15, 2018, including adoption in an interim period using a modified-retrospective approach. We are currently evaluating the impact of the adoption of this guidance on Brookfield DTLA’s consolidated financial statements.

Mezzanine Equity

Mezzanine Equity	6 Months Ended
	Jun. 30, 2018
Temporary Equity Disclosure [Abstract]
Mezzanine Equity	Mezzanine Equity Mezzanine equity in the condensed consolidated balance sheets is comprised of the Series A preferred stock, a Series A-1 preferred interest, a senior participating preferred interest, and a Series B preferred interest (collectively, the “Preferred Interests”). The Series A-1 preferred interest, senior participating preferred interest and Series B preferred interest are held by a noncontrolling interest holder. The Preferred Interests are classified in mezzanine equity because they are callable, and the holder of the Series A-1 preferred interest, senior participating preferred interest, Series B preferred interest, and some of the Series A preferred stock indirectly controls the ability to elect to redeem such instruments, through its controlling interest in the Company and its subsidiaries. There is no commitment or obligation on the part of Brookfield DTLA or DTLA Holdings to redeem the Preferred Interests. The Preferred Interests included within mezzanine equity were recorded at fair value on the date of issuance and have been adjusted to the greater of their carrying amount or redemption value as of June 30, 2018 and December 31, 2017 . Adjustments to increase the carrying amount to redemption value are recorded in the condensed consolidated statement of operations as a redemption measurement adjustment. Series A Preferred Stock As of June 30, 2018 and December 31, 2017 , 9,730,370 shares of Series A preferred stock were outstanding, of which 9,357,469 shares were issued to third parties and 372,901 shares were issued to DTLA Fund Holding Co., a subsidiary of DTLA Holdings. No dividends were declared on the Series A preferred stock during the six months ended June 30, 2018 and 2017 . Dividends on the Series A preferred stock are cumulative, and therefore, will continue to accrue at an annual rate of $1.90625 per share. As of June 30, 2018 , the cumulative amount of unpaid dividends totals $157.4 million and has been reflected in the carrying amount of the Series A preferred stock. The Series A preferred stock does not have a stated maturity and is not subject to any sinking fund or mandatory redemption provisions. Upon liquidation, dissolution or winding up, the Series A preferred stock will rank senior to our common stock with respect to the payment of distributions. We may, at our option, redeem the Series A preferred stock, in whole or in part, for cash at a redemption price of $25.00 per share, plus all accumulated and unpaid dividends on such Series A preferred stock up to and including the redemption date. The Series A preferred stock is not convertible into or exchangeable for any other property or securities of Brookfield DTLA. As of June 30, 2018 , the Series A preferred stock is reported at its redemption value of $400.7 million calculated using the redemption price of $25.00 per share plus all accumulated and unpaid dividends on such Series A preferred stock through June 30, 2018 . Series A-1 Preferred Interest The Series A-1 preferred interest is held by DTLA Holdings or wholly owned subsidiaries of DTLA Holdings and has a stated value of $225.7 million . The Series A-1 preferred interest has mirror rights to the Series A preferred interests issued by Brookfield DTLA Fund Properties II LLC (“New OP”), which are held by a wholly owned subsidiary of Brookfield DTLA, but only with respect to their respective preferred liquidation preferences, and share pro rata with 48.13% to the Series A-1 preferred interest and 51.87% to the Series A preferred interest based on their current liquidation preferences in accordance with their respective preferred liquidation preferences in distributions from New OP, until their preferred liquidation preferences have been reduced to zero. Thereafter, distributions will be made 47.66% to the common component of the Series A interest and 52.34% to the common component of the Series B interest, which is held by DTLA Holdings. The economic terms of the Series A preferred stock mirror those of the New OP Series A preferred interests, including distributions in respect of the preferred liquidation preference. As of June 30, 2018 , the Series A-1 preferred interest is reported at its redemption value of $392.1 million calculated using its liquidation value of $225.7 million plus $166.4 million of accumulated and unpaid dividends on such Series A-1 preferred interest through June 30, 2018 . Senior Participating Preferred Interest Brookfield DTLA Fund Properties III LLC (“DTLA OP”) issued a senior participating preferred interest to DTLA Holdings in connection with the formation of Brookfield DTLA and the MPG acquisition. As of June 30, 2018 and December 31, 2017 , the senior participating preferred interest represents a 4.0% participating interest in the residual value of DTLA OP. During the six months ended June 30, 2018 , Brookfield DTLA made distributions totaling $2.0 million to DTLA Holdings as returns of investment related to the senior participating preferred interest using cash on hand. As of June 30, 2018 , the senior participating preferred interest is reported at its redemption value of $25.9 million using the value of the participating interest. Series B Preferred Interest At the time of the merger with MPG, DTLA Holdings made a commitment to make capital contributions in cash or property to New OP, which directly or indirectly owns the Brookfield DTLA properties, to fund up to $260.0 million of its future cash needs, for which it will be entitled to receive a preferred return, if and when called by New OP. The Series B preferred interest in New OP held by DTLA Holdings is effectively senior to the interest in New OP held by Brookfield DTLA and has a priority on distributions senior to the equity securities of such subsidiaries held indirectly by Brookfield DTLA and, as a result, effectively rank senior to the Series A preferred stock. The Series B preferred interest in New OP may limit the amount of funds available to Brookfield DTLA for any purpose, including for dividends or other distributions to holders of its capital stock, including the Series A preferred stock. During the six months ended June 30, 2018 , Brookfield DTLA made distributions totaling $12.5 million to DTLA Holdings as preferred returns on the Series B preferred interest using cash on hand. As of June 30, 2018 , the Series B preferred interest is reported at its redemption value of $185.6 million calculated using its liquidation value of $174.8 million plus $10.8 million of accumulated and unpaid dividends on such Series B preferred interest through June 30, 2018 . Change in Mezzanine Equity A summary of the change in mezzanine equity for the six months ended June 30, 2018 is as follows (in thousands, except share amounts): Number of Shares of Series A Preferred Stock Series A Preferred Stock Noncontrolling Interests Total Mezzanine Equity Series A-1 Preferred Interest Senior Participating Preferred Interest Series B Preferred Interest Balance, December 31, 2017 9,730,370 $ 391,400 $ 383,510 $ 25,548 $ 190,291 $ 990,749 Current dividends 9,274 8,606 — 7,800 25,680 Distributions to holders (2,025 ) (12,458 ) (14,483 ) Redemption measurement adjustment 2,425 2,425 Balance, June 30, 2018 9,730,370 $ 400,674 $ 392,116 $ 25,948 $ 185,633 $ 1,004,371

These noncontrolling interests are presented as mezzanine equity in the condensed consolidated balance sheet. See Note 8 “Mezzanine Equity.” Stockholders’ Deficit Component The Series B common interest ranks junior to the Series A preferred stock as to dividends and upon liquidation and is presented in the condensed consolidated balance sheet as noncontrolling interest.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income Taxes Brookfield DTLA has elected to be taxed as a real estate investment trust (“REIT”) pursuant to Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”), commencing with its tax period ended December 31, 2013. Brookfield DTLA conducts and intends to conduct its operations so as to continue to qualify as a REIT. Accordingly, Brookfield DTLA is not subject to U.S. federal income tax, provided that it continues to qualify as a REIT and distributions to its stockholders, if any, generally equal or exceed its taxable income. Brookfield DTLA has elected to treat certain of its subsidiaries as taxable REIT subsidiaries (“TRS”). Certain activities that we undertake must be conducted by a TRS, such as non-customary services for our tenants, and holding assets that we cannot hold directly. A TRS is subject to both federal and state income taxes. Qualification and taxation as a REIT depends upon Brookfield DTLA’s ability to meet the various qualification tests imposed under the Code related to annual operating results, asset diversification, distribution levels and diversity of stock ownership. Accordingly, no assurance can be given that Brookfield DTLA will be organized or be able to operate in a manner so as to continue to qualify as a REIT. If Brookfield DTLA fails to qualify as a REIT in any taxable year, we will be subject to federal and state income tax on our taxable income at regular corporate tax rates, and we may be ineligible to qualify as a REIT for four subsequent tax years. Brookfield DTLA may be subject to certain state or local income taxes, or franchise taxes on its REIT activities. Brookfield DTLA recorded provisions for income taxes of $1.7 million and $0.2 million during the six months ended June 30, 2018 and 2017 , respectively. The income tax provision for the six months ended June 30, 2018 is primarily the result of the sale of artwork no longer on display at our Wells Fargo Center office properties due to renovation activities. Brookfield DTLA’s taxable income or loss is different than its financial statement income or loss. On December 22, 2017, the Tax Cuts and Jobs Act (the “Act”) was signed into law. The Act amended the Code to reduce tax rates and modify policies, credits, and deductions for individuals and businesses. Effective January 1, 2018, the Act reduced the corporate tax rate from a maximum rate of 35% to a flat rate of 21% for businesses. Since Brookfield DTLA has elected to qualify as a REIT with the intent of distributing 100% of its taxable income, there was no material impact to the Company’s condensed consolidated financial statements . Uncertain Tax Positions Brookfield DTLA recognizes tax benefits from uncertain tax positions when it is more likely than not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits. Income tax positions must meet a more likely than not recognition threshold. Brookfield DTLA had no unrecognized tax benefits as of June 30, 2018 and December 31, 2017 , and Brookfield DTLA does not expect its unrecognized tax benefits balance to change during the next 12 months. As of June 30, 2018 , Brookfield DTLA’s 2013 tax period and 2014, 2015 and 2016 tax years remain open due to the statute of limitations and may be subject to examination by federal, state and local authorities.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The valuation of Brookfield DTLA’s interest rate swaps is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of the derivatives. These analyses reflect the contractual terms of the derivatives, including the period to maturity, and use observable market-based inputs, including interest rate curves and implied volatilities. We have incorporated credit valuation adjustments to appropriately reflect both our own and the respective counterparty’s non-performance risk in the fair value measurements. Brookfield DTLA’s net assets (liabilities) measured at fair value on a recurring basis, aggregated by the level in the fair value hierarchy within which those measurements fall, are as follows (in thousands): Fair Value Measurements Using Total Fair Value Quoted Prices in Active Markets for Identical Assets (Liabilities) (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Interest rate swaps at: June 30, 2018 $ 1,963 $ — $ 1,963 $ — December 31, 2017 (574 ) — (574 ) — Interest rate caps at: June 30, 2018 $ 37 $ — $ 37 $ — December 31, 2017 15 — 15 —

Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The accompanying unaudited condensed consolidated financial statements and related disclosures have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) applicable to interim financial information and with the instructions to Form 10‑Q and Rule 10-01 of Regulation S-X. In the opinion of management, all adjustments, consisting of only those of a normal and recurring nature, considered necessary for a fair presentation of the financial position and interim results of Brookfield DTLA as of and for the periods presented have been included. The results of operations for interim periods are not necessarily indicative of those that may be expected for a full fiscal year. The condensed consolidated balance sheet data as of December 31, 2017 has been derived from Brookfield DTLA’s audited financial statements; however, the accompanying notes to the condensed consolidated financial statements do not include all disclosures required by GAAP. The financial information included herein should be read in conjunction with the consolidated financial statements and related notes included in Brookfield DTLA’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 27, 2018 .
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. For example, estimates and assumptions have been made with respect to fair values of assets and liabilities for purposes of applying the acquisition method of accounting, the useful lives of assets, recoverable amounts of receivables, impairment of long-lived assets and fair value of debt. Actual results could ultimately differ from such estimates.
Recent Accounting Pronouncements	Accounting Pronouncements Adopted in 2018 Effective January 1, 2018, Brookfield DTLA adopted the guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2016-18, Restricted Cash to Accounting Standards Codification (“ASC”) Topic 230, Statement of Cash Flows. ASU 2016-18 requires entities to show the change during the period in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the statement of cash flows. We adopted ASU 2016-18 on a retrospective basis. Therefore, amounts generally described as restricted cash and restricted cash equivalents are included with cash and cash equivalents when reconciling the beginning of period and end of period total amounts shown in the Company’s condensed consolidated statements of cash flows for the six months ended June 30, 2018 and 2017 . As a result of the adoption of ASU 2016-18, the change in restricted cash is no longer presented as a separate line item within cash flows from investing activities in the condensed consolidated statement of cash flows since such balances are now included in total cash at both the beginning and end of the reporting period. As a result, for the six months ended June 30, 2017 the Company used net cash in investing activities of $26.5 million instead of $14.7 million as previously reported. Effective January 1, 2018, Brook field DTLA adopted, on a modified retrospective basis, the guidance in ASU 2014-09, Revenue from Contracts with Customers (ASC Topic 606). ASU 2014-09, as amended by subsequent ASUs on the topic, establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most of the existing revenue recognition guidance. ASU 2014-09 requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration that the entity expects to be entitled to receive in exchange for those goods or services and also requires certain additional disclosures. The adoption of this pronouncement did not have an impact on Brookfield DTLA’s condensed consolidated financial statements . Effective January 1, 2018, Broo kfield DTLA adopted, on a retrospective basis, the guidance in ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments to ASC Topic 230, Statement of Cash Flows . ASU 2016-15 clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The adoption of this guidance did not have an impact on Brookfield DTLA’s condensed consolidated financial statements . Effective January 1, 2018, Bro okfield DTLA adopted, on a prospective basis, the guidance in ASU 2017-01, Clarifying the Definition of a Business to ASC Topic 805, Business Combinations. ASU 2017-01 introduced amendments that are intended to make the guidance on the definition of a business more consistent and cost-efficient. The objective of the update is to add further guidance that assists entities in evaluating whether a transaction should be accounted for as an acquisition (or disposal) of assets or as a business by providing a basis to determine when a set of assets and activities acquired is not a business. We expect that future acquisitions of operating and development properties, if any, will be accounted for as asset acquisitions under the new guidance, instead of as business combinations under the previous guidance. Additionally, we expect that most of the transaction costs associated with any future acquisitions will be capitalized in the consolidated balance sheet as part of the purchase price of the property acquired instead of being expensed as incurred in the consolidated statement of operations as part of acquisition-related expenses. Effective January 1, 2018, Brookfield DTLA adopted, on a retrospective basis, the guidance in ASU 2017-05, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets to ASC Subtopic 610-20, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets . ASU 2017-05 clarifies the scope of recently established guidance on nonfinancial asset derecognition as well as the accounting for partial sales of nonfinancial assets. This update conforms the derecognition guidance on nonfinancial assets with the model for transactions in ASC 606. The adoption of this guidance did not have an impact on Brookfield DTLA’s condensed consolidated financial statements . Accounting Pronouncements Effective January 1, 2019 Leases In February 2016, the FASB issued an update (“ASU 2016-02”) to ASC Topic 842, Leases, to amend the accounting guidance for leases. ASU 2016-02 sets out the principles for the recognition, measurement, presentation, and disclosure of leases for both lessees and lessors. The guidance requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on a principle of whether or not the lease is effectively a financed purchase. For all leases with a term greater than 12 months, lessees are required to record a right-of-use asset representing its right to use the underlying asset for the lease term and a liability to make lease payments on its balance sheet and will recognize lease expense generally on a straight‑line basis over the lease term in its statement of operations. For leases with a term of 12 months or less, lessees are permitted to make an accounting policy election by class of underlying asset not to recognize lease assets or liabilities on its balance sheet. If a lessee makes this election, it will recognize lease expense for such leases using the effective interest method. We are currently evaluating the impact of the adoption of ASU 2016-02 on Brookfield DTLA’s consolidated financial statements, and we currently believe that the adoption of this standard will not significantly change the accounting for operating leases on Brookfield DTLA’s consolidated balance sheet where we are the lessor, and that such leases will be accounted for in a similar manner. Under ASU 2016 ‑ 02, initial direct costs for both lessees and lessors will include only those costs that are incremental to the arrangement and would not have been incurred if the lease had not been obtained. As a result, Brookfield DTLA may no longer be able to capitalize internal leasing costs and instead may be required to expense these costs as incurred. ASU 2016-02 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2018, with early adoption permitted. In January 2018, the FASB released an exposure draft to amend ASU 2016-02 that would (1) simplify transition requirements for both lessees and lessors by adding an option that would permit an organization to apply the transition provisions of the new standard at its adoption date instead of at the earliest comparative period presented in its financial statements and (2) provide a practical expedient for lessors that would permit lessors to make an accounting election to not separate nonlease components from the associated lease components if certain criteria are met. In March 2018, the FASB finalized the changes with respect to optional transition relief and approved a practical expedient for lessors that would permit lessors to make an accounting policy election to not separate nonlease components from the associated lease components, by class of underlying asset, if the following two criteria are met: (1) the timing and pattern of transfer of the lease and nonlease components are the same and (2) the lease component would be classified as an operating lease if accounted for separately. For leases where we are the lessor, we currently believe that we will elect the optional transition relief and that we will meet the noted criteria to not be required to bifurcate and separately report nonlease components, such as common area maintenance revenue, for operating leases in our consolidated statement of operations. As a result, we currently believe that leases where we are the lessor will be accounted for in a similar method to existing standards with the underlying leased asset being reported and recognized as a real estate asset. The FASB is expected to issue an ASU codifying these changes. We currently expect to adopt this standard effective January 1, 2019 using the practical expedients proposed in the standard and the changes approved by the FASB. Other In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities to ASC Topic 815, Derivatives and Hedging . ASU 2017-12 introduced amendments intended to make targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. The objective of the update is to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. ASU 2017-12 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2018, with early adoption permitted, including adoption in an interim period. All transition requirements and elections should be applied to hedging relationships existing as of the date of adoption and the effect of the adoption should be reflected as of the beginning of the fiscal year of adoption. We are currently evaluating the impact of the adoption of this guidance on Brookfield DTLA’s consolidated financial statements. Accounting Pronouncements Effective January 1, 2020 In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, to amend the accounting for credit losses for certain financial instruments. Under the new guidance, an entity recognizes its estimate of expected credit losses as an allowance, which the FASB believes will result in more timely recognition of such losses. ASU 2016-13 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2019, with early adoption permitted as of the fiscal year beginning after December 15, 2018, including adoption in an interim period using a modified-retrospective approach. We are currently evaluating the impact of the adoption of this guidance on Brookfield DTLA’s consolidated financial statements.
