Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	Organization and Description of Business Brookfield DTLA Fund Office Trust Investor Inc. (“Brookfield DTLA” or the “Company”) is a Maryland corporation and was incorporated on April 19, 2013. Brookfield DTLA was formed for the purpose of consummating the transactions contemplated in the Agreement and Plan of Merger dated as of April 24, 2013, as amended (the “Merger Agreement”), and the issuance of shares of 7.625% Series A Cumulative Redeemable Preferred Stock (the “Series A preferred stock”) in connection with the acquisition of MPG Office Trust, Inc. and MPG Office, L.P. (together, “MPG”). Brookfield DTLA is a direct subsidiary of Brookfield DTLA Holdings LLC (“Brookfield DTLA Holdings”), a Delaware limited liability company, and an indirect partially-owned subsidiary of Brookfield Office Properties Inc., a corporation under the Laws of Canada (“BPO”, and together with its affiliates excluding the Company and its subsidiaries, the “Manager”). Brookfield DTLA owns BOA Plaza, EY Plaza, Wells Fargo Center–North Tower, Wells Fargo Center–South Tower, Gas Company Tower and 777 Tower, each of which is a Class A office property located in the Los Angeles Central Business District (the “LACBD”). Brookfield DTLA receives its income primarily from rental income (including tenant reimbursements) generated from the operations of its office and retail properties, and to a lesser extent, from its parking garages.

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, 2016 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 20, 2017 . 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 In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2014-09 establishing Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers. ASU 2014-09 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. ASU 2014-09 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2017. We are currently evaluating the impact of the adoption of ASU 2014-09 on Brookfield DTLA’s consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 establishing ASC Topic 842, Leases . The guidance in this update supersedes the guidance in ASC Topic 840, Leases . ASU 2016-02 revises GAAP related to accounting for leases by lessees. Under this new guidance, lessees will be required to recognize a lease liability and a right-of-use asset in the balance sheet for all leases with terms greater than 12 months. Leases will be classified as either finance or operating, with classification determining the pattern of expense recognition in the statement of operations. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and should be applied using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2016-02 on Brookfield DTLA’s consolidated financial statements. In August 2016, the FASB issued 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 with respect to (i) debt prepayment or debt extinguishment costs, (ii) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, (iii) contingent consideration payments made after a business combination, (iv) proceeds from the settlement of insurance claims, (v) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, (vi) distributions received from equity method investees, (vii) beneficial interests in securitization transactions, and (viii) separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2017, with early adoption permitted. We do not expect the adoption of this update to have a material impact on Brookfield DTLA’s consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Restricted Cash to ASC Topic 230, Statement of Cash Flows . ASU 2016-18 requires entities to show the changes in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. Upon adoption, we will retrospectively reconcile the activity in our cash, cash equivalents, restricted cash and restricted cash equivalents during reporting periods. In January 2017, the FASB issued 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 a business by providing a screen to determine when a set of assets and activities acquired is not a business. ASU 2017-01 is effective for annual periods beginning after December 15, 2017 including interim periods within those periods. ASU 2017-01 must be applied prospectively on or after the effective date. We are currently evaluating the impact of the adoption of ASU 2017-01 on Brookfield DTLA’s consolidated financial statements. In February 2017, the FASB issued 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. ASU 2017-05 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. We do not expect the adoption of this update to have a material impact on Brookfield DTLA’s consolidated financial statements. 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 fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is 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 ASU 2017-01 on Brookfield DTLA’s consolidated financial statements. 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, it will be subject to federal and state income tax on its taxable income at regular corporate tax rates, and it may be ineligible to qualify as a REIT for four subsequent tax years. Brookfield DTLA may also be subject to certain state or local income taxes, or franchise taxes on its REIT activities. Brookfield DTLA made provisions for income taxes of $291 thousand and $482 thousand during the three and nine months ended September 30, 2017 , respectively. Brookfield DTLA made no provision and a $419 thousand provision for income taxes during the three and nine months ended September 30, 2016 , respectively. Brookfield DTLA’s taxable income or loss is different than its financial statement income or loss. 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 September 30, 2017 and December 31, 2016 , and Brookfield DTLA does not expect its unrecognized tax benefits balance to change during the next 12 months. As of September 30, 2017 , 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. The short tax period ended October 15, 2013 for Brookfield DTLA and its subsidiaries remains open due to the statute of limitations and may be subject to examination by federal, state and local tax authorities.

During April 2017, the Company received an $82.0 million cash contribution from Brookfield DTLA Holdings that was used to pay for costs associated with the refinancing of Wells Fargo Center–North Tower. The new $470.0 million loan is comprised of a $370.0 million mortgage loan, a $55.0 million mezzanine loan and a $45.0 million mezzanine loan, each of which bears interest at variable rates equal to LIBOR plus 2.25% , 5.25% and 7.00% , respectively, and require the payment of interest-only until maturity.

Debt Maturities As Brookfield DTLA’s debt matures, principal payment obligations present significant future cash requirements. As of September 30, 2017 , our debt to be repaid during the remainder of 2017 , the next four years and thereafter is as follows (in thousands): 2017 (1) $ 36,025 2018 474,233 2019 474,449 2020 168,151 2021 450,000 Thereafter 400,000 $ 2,002,858 __________ (1) On November 2, 2017 , Brookfield DTLA extended the maturity date of the $35.0 million mortgage loan secured by Figueroa at 7th from December 10, 2017 until January 8, 2018 .

See Note 14 “Subsequent Event.” Non-Recourse Carve Out Guarantees All of Brookfield DTLA’s $2.0 billion of mortgage debt is subject to “non-recourse carve out” guarantees that expire upon elimination of the underlying loan obligations. In connection with all of these loans, Brookfield DTLA entered into “non-recourse carve out” guarantees, which provide for these otherwise non-recourse loans to become partially or fully recourse against Brookfield DTLA Holdings or one of its subsidiaries, if certain triggering events (as defined in the loan agreements) occur. Debt Reporting Pursuant to the terms of certain of our mortgage loan agreements, Brookfield DTLA is required to report a debt service coverage ratio (“DSCR”) calculated using the formulas specified in the underlying loan agreements.

Mezzanine Equity

Mezzanine Equity	9 Months Ended
	Sep. 30, 2017
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 Brookfield 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 September 30, 2017 and December 31, 2016 . 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 September 30, 2017 and December 31, 2016 , 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 Brookfield DTLA Holdings. No dividends were declared on the Series A preferred stock during the nine months ended September 30, 2017 and 2016 . 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 September 30, 2017 , the cumulative amount of unpaid dividends totals $143.5 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 September 30, 2017 , the Series A preferred stock is reported at its redemption value of $386.8 million calculated using the redemption price of $25.00 per share plus all accumulated and unpaid dividends on such Series A preferred stock through September 30, 2017 . Series A-1 Preferred Interest The Series A-1 preferred interest is held by Brookfield DTLA Holdings or wholly owned subsidiaries of Brookfield DTLA Holdings. 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 Brookfield 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 September 30, 2017 , the Series A-1 preferred interest is reported at its redemption value of $379.2 million calculated using its liquidation value of $225.7 million plus $153.5 million of accumulated and unpaid dividends on such Series A-1 preferred interest through September 30, 2017 . Senior Participating Preferred Interest Brookfield DTLA Fund Properties III LLC (“DTLA OP”) issued a senior participating preferred interest to Brookfield DTLA Holdings in connection with the formation of Brookfield DTLA and the MPG acquisition. The senior participating preferred interest was comprised of $240.0 million in preferred interests with a 7.0% coupon and a 4.0% participating interest in the residual value of DTLA OP. During the nine months ended September 30, 2017 , the Company received a net cash contribution totaling $250 thousand from Brookfield DTLA Holdings, which was used for general corporate purposes. As of September 30, 2017 , the senior participating preferred interest is reported at its redemption value of $25.5 million using the value of the participating interest. Series B Preferred Interest At the time of the merger with MPG, Brookfield 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 Brookfield 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. On February 27, 2017 , the Company received a $29.5 million cash contribution from Brookfield DTLA Holdings, which is entitled to a preferred return of 9.0% as part of the Series B preferred interest. The Company used these funds for general corporate purposes. On April 4, 2017 , the Company received an $82.0 million cash contribution from Brookfield DTLA Holdings, which is entitled to a preferred return of 9.0% as part of the Series B preferred interest. The Company used these funds to pay for costs associated with the refinancing of the Wells Fargo Center–North Tower mortgage loan. As of September 30, 2017 , the Series B preferred interest is reported at its redemption value of $186.3 million calculated using its liquidation value of $174.8 million plus $11.5 million of accumulated and unpaid dividends on such Series B preferred interest through September 30, 2017 . Change in Mezzanine Equity A summary of the change in mezzanine equity for the nine months ended September 30, 2017 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, 2016 9,730,370 $ 372,852 $ 366,297 $ 25,019 $ 65,364 $ 829,532 Issuance of Series B preferred interest 111,492 111,492 Current dividends 13,911 12,909 — 9,470 36,290 Contribution from senior participating preferred interest, net 250 250 Redemption measurement adjustment 250 250 Balance, September 30, 2017 9,730,370 $ 386,763 $ 379,206 $ 25,519 $ 186,326 $ 977,814

Fair Value Measurements	Fair Value Measurements The valuation of Brookfield DTLA’s interest rate swap is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flow of the derivative. This analysis reflects the contractual terms of the derivative, including the period to maturity, and uses 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.

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, 2016 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 20, 2017 .
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	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2014-09 establishing Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers. ASU 2014-09 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. ASU 2014-09 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2017. We are currently evaluating the impact of the adoption of ASU 2014-09 on Brookfield DTLA’s consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 establishing ASC Topic 842, Leases . The guidance in this update supersedes the guidance in ASC Topic 840, Leases . ASU 2016-02 revises GAAP related to accounting for leases by lessees. Under this new guidance, lessees will be required to recognize a lease liability and a right-of-use asset in the balance sheet for all leases with terms greater than 12 months. Leases will be classified as either finance or operating, with classification determining the pattern of expense recognition in the statement of operations. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and should be applied using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2016-02 on Brookfield DTLA’s consolidated financial statements. In August 2016, the FASB issued 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 with respect to (i) debt prepayment or debt extinguishment costs, (ii) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, (iii) contingent consideration payments made after a business combination, (iv) proceeds from the settlement of insurance claims, (v) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, (vi) distributions received from equity method investees, (vii) beneficial interests in securitization transactions, and (viii) separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2017, with early adoption permitted. We do not expect the adoption of this update to have a material impact on Brookfield DTLA’s consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Restricted Cash to ASC Topic 230, Statement of Cash Flows . ASU 2016-18 requires entities to show the changes in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. Upon adoption, we will retrospectively reconcile the activity in our cash, cash equivalents, restricted cash and restricted cash equivalents during reporting periods. In January 2017, the FASB issued 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 a business by providing a screen to determine when a set of assets and activities acquired is not a business. ASU 2017-01 is effective for annual periods beginning after December 15, 2017 including interim periods within those periods. ASU 2017-01 must be applied prospectively on or after the effective date. We are currently evaluating the impact of the adoption of ASU 2017-01 on Brookfield DTLA’s consolidated financial statements. In February 2017, the FASB issued 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. ASU 2017-05 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. We do not expect the adoption of this update to have a material impact on Brookfield DTLA’s consolidated financial statements. 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 fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is 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 ASU 2017-01 on Brookfield DTLA’s consolidated financial statements.
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, it will be subject to federal and state income tax on its taxable income at regular corporate tax rates, and it may be ineligible to qualify as a REIT for four subsequent tax years. Brookfield DTLA may also be subject to certain state or local income taxes, or franchise taxes on its REIT activities. Brookfield DTLA made provisions for income taxes of $291 thousand and $482 thousand during the three and nine months ended September 30, 2017 , respectively. Brookfield DTLA made no provision and a $419 thousand provision for income taxes during the three and nine months ended September 30, 2016 , respectively. Brookfield DTLA’s taxable income or loss is different than its financial statement income or loss. 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 September 30, 2017 and December 31, 2016 , and Brookfield DTLA does not expect its unrecognized tax benefits balance to change during the next 12 months. As of September 30, 2017 , 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. The short tax period ended October 15, 2013 for Brookfield DTLA and its subsidiaries remains open due to the statute of limitations and may be subject to examination by federal, state and local tax authorities.
