| Basis of Presentation and Summary of Significant Accounting Policies | Basis of Presentation and Summary of Significant Accounting Policies As used in these 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. together with its direct and indirect subsidiaries. Principles of Consolidation and Basis of Presentation The accompanying consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“ GAAP ”). The consolidated balance sheets as of December 31, 2019 and 2018 include the accounts of Brookfield DTLA and subsidiaries in which it has a controlling financial interest. All intercompany transactions have been eliminated in consolidation as of and for the years ended December 31, 2019 , 2018 and 2017 . Determination of Controlling Financial Interest In determining whether Brookfield DTLA has a controlling financial interest in an entity and the requirement to consolidate the accounts of that entity, management considers factors such as ownership interest, board representation, management representation, authority to make decisions, and contractual and substantive participating rights of the partners/members as well as whether the entity is a variable interest entity (“ VIE ”) and Brookfield DTLA is the primary beneficiary. A VIE is broadly defined as an entity where either (i) the equity investors as a group, if any, lack the power through voting or similar rights to direct the activities of an entity that most significantly impact the entity’s economic performance or (ii) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support. A variable interest holder is considered to be the primary beneficiary of a VIE if it has the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and has the obligation to absorb the losses of, or the right to receive benefits from, the entity that could potentially be significant to the VIE. Brookfield DTLA qualitatively assesses whether it is (or is not) the primary beneficiary of a VIE. Consideration of various factors includes, but is not limited to, Brookfield DTLA’s ability to direct the activities that most significantly impact the VIE’s economic performance, its form of ownership interest, its representation on the VIE’s governing body, the size and seniority of its investment, its ability and the rights of other investors to participate in policy making decisions, and its ability to replace the manager of and/or liquidate the entity. Brookfield DTLA is required to continually evaluate its VIE relationships and consolidation conclusion. Brookfield DTLA Fund Properties II LLC. The Company earns a return through an indirect investment in New OP. DTLA Holdings, the parent of Brookfield DTLA, owns all of the common interest in New OP. Brookfield DTLA has an indirect preferred stock interest in New OP and its wholly owned subsidiary is the managing member of New OP. The Company determined that New OP is a VIE and as a result of having the power to direct the significant activities of New OP and exposure to the economic performance of New OP, Brookfield DTLA meets the two conditions for being the primary beneficiary. Investment in Unconsolidated Real Estate Joint Venture. New OP has noncontrolling interests in a joint venture with DTLA FP IV Holdings. The Company determined that the joint venture is a VIE mainly because its equity investment at risk is insufficient to finance the joint venture’s activities without additional subordinated financial support. While the joint venture meets the definition of a VIE, Brookfield DTLA is not its primary beneficiary as the Company lacks the power through voting or similar rights to direct the activities that most significantly impact the joint venture’s economic performance. Therefore, the Company accounts for its ownership interest in the joint venture under the equity method. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods presented. For example, estimates and assumptions have been made with respect to the fair value of assets and liabilities for purposes of the contribution of its wholly-owned interests in exchange for noncontrolling interests in a joint venture, the useful lives of assets, recoverable amounts of receivables, impairment of long‑lived assets and the fair value of debt. Actual results could ultimately differ from such estimates. Restatements In January 2018, Brookfield DTLA adopted, on a retrospective basis, the guidance in Accounting Standards Update (“ ASU ”) 2016-18, Restricted Cash , which requires entities to include restricted cash with cash and cash equivalents when reconciling the beginning and end of period total amounts shown in the statement of cash flows. Therefore, the change in restricted cash is no longer presented as a separate line item within cash flows from investing activities in the Company’s consolidated statement of cash flows since such balances are now combined with cash and cash equivalents at both the beginning and end of the reporting period. We have retroactively restated the consolidated statement of cash flows for the year ended December 31, 2017 by reclassifying the decrease in restricted cash of $24.5 million from cash flows used in investing activities to net change in cash, cash equivalents and restricted cash. Reclassifications On January 1, 2019 , Brookfield DTLA adopted Accounting Standards Codification (“ ASC ”) Topic 842, Leases, using the modified retrospective transition method. Please refer to Note 3—“Leases” for a discussion of the reclassification of rental income and tenant reimbursements in the consolidated statements of operations for the years ended December 31, 2018 and 2017 . During the year ended December 31, 2018 , the Company reclassified asset management fees earned by BPY and BAM from rental property operating and maintenance expense to other expense in the consolidated statement of operations. Management does not include asset management fees as an input when evaluating the operating performance of Brookfield DTLA’s properties and created a new category within other expense during 2018 to capture such fees. For the year ended December 31, 2017 , the Company reported rental property operating and maintenance expense totaling $100.3 million and other expense totaling $5.2 million in the consolidated statement of operations. After the reclassification, rental property operating and maintenance expense now totals $94.0 million and other expense now totals $11.5 million in the consolidated statement of operations for the year ended December 31, 2017 . This reclassification had no effect on the Company’s financial position, results of operations or cash flows. During the year ended December 31, 2018 , the Company also reclassified lease termination fees from interest and other income to rental income in the consolidated statement of operations in anticipation of adopting ASU 2016-02, Leases (Topic 842) . For the year ended December 31, 2017 , the Company reported interest and other income totaling $10.3 million and rental income totaling $162.4 million in the consolidated statement of operations. After the reclassification, interest and other income now totals $7.0 million and rental income now totals $165.7 million in the consolidated statement of operations for the year ended December 31, 2017 . See Note 3—“Leases” for reconciliation of lease income reported for the year ended December 31, 2017 in the current year’s consolidated statement of operations after the adoption of Topic 842. This reclassification had no effect on the Company’s financial position, results of operations or cash flows. Significant Accounting Policies Investments in Real Estate, Net— Land is carried at cost. Buildings are recorded at historical cost and are depreciated on a straight‑line basis over their estimated useful lives of 60 years. Building improvements are recorded at historical cost and depreciated on a straight-line basis over their estimated useful lives, which range from 5 years to 25 years. Land improvements are combined with building improvements for financial reporting purposes and are carried at cost. Tenant improvements that are determined to be assets of Brookfield DTLA are recorded at cost and amortized on a straight‑line basis over the shorter of their estimated useful life or the applicable lease term, with the related amortization reported as part of depreciation and amortization expense in the consolidated statement of operations. Depreciation expense related to investments in real estate during the years ended December 31, 2019 , 2018 and 2017 totaled $85.6 million , $75.7 million and $73.6 million , respectively, and is reported as part of depreciation and amortization expense in the consolidated statements of operations. Investments in real estate are reviewed for impairment if events or changes in circumstances indicate that the carrying amount of the real estate may not be recoverable. In such an event, a comparison is made between (i) the current and projected operating cash flows of the property into the foreseeable future on an undiscounted basis and (ii) the carrying amount of the property. If the undiscounted cash flows expected to be generated by a property are less than its carrying amount, an impairment provision would be recorded to write down the carrying amount of such property to its fair value. Brookfield DTLA assesses fair value based on estimated cash flow projections utilizing appropriate discount and capitalization rates and available market information. Projections of future cash flows take into account the specific business plan for the property and management’s best estimate of the most probable set of economic conditions expected to prevail in the market. Management believes no impairment of Brookfield DTLA’s real estate properties existed at December 31, 2019 and 2018 . Investment in Unconsolidated Real Estate Joint Venture— As discussed in Note 1—“Organization and Description of Business,” on May 31, 2019 New OP entered into an agreement to contribute and transfer all of its wholly‑owned interests in the Property Owner in exchange for noncontrolling interests in a newly formed joint venture with DTLA FP IV Holdings. The liabilities of the joint venture may only be settled using the assets of 755 South Figueroa and are not recourse to the Company. Brookfield DTLA’s exposure to its investment in the joint venture is limited to its investment balance and the Company has no obligation to future contributions to the joint venture. Pursuant to the operating agreement of the joint venture, DTLA FP IV Holdings may be required to fund additional amounts for the development of 755 South Figueroa, routine operating costs, and guaranties or commitments of the joint venture. Our noncontrolling interests in the joint venture were initially recorded at the fair value of the assets contributed and have been adjusted to redemption value as of December 31, 2019 . Adjustments to increase or decrease the carrying amount to redemption value are recorded in the consolidated statement of operations as equity in loss of unconsolidated real estate joint venture. Cash and Cash Equivalents— Cash and cash equivalents include cash, deposits with major commercial banks, and short-term investments with an original maturity of three months or less. Restricted Cash— Restricted cash consists primarily of deposits for tenant improvements and leasing commissions, reserves for real estate taxes and insurance, and other items as required by certain of the Company’s secured debt agreements. Rents, Deferred Rents and Other Receivables, Net— Deferred rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. Rents, deferred rents and other receivables, net also includes amounts paid to a tenant for improvements owned or costs incurred by the tenant. Such amounts are treated as tenant inducements and are presented in the consolidated balance sheet net of accumulated amortization. Amortization of tenant inducements is recorded on a straight-line basis over the term of the related lease as a reduction of lease income in the consolidated statement of operations. See Note 5—“Rents, Deferred Rents and Other Receivables, Net.” In addition, under Topic 842, Brookfield DTLA must assess on an individual lease basis whether it is probable that the Company will collect the future lease payments throughout the lease term. The Company considers the tenant’s payment history and current credit status when assessing collectability. If the collectability of the lease payments is probable at lease commencement, the Company recognizes lease income over the lease term on a straight-line basis. When collectability is not deemed probable at the commencement date, the Company’s lease income is constrained to the lesser of (1) the income that would have been recognized if collection were probable, and (2) the lease payments that have been collected from the lessee. If the collectability assessment changes to probable after the commencement date, any difference between the lease income that would have been recognized if collectability had always been assessed as probable and the lease income recognized to date is recognized as a current-period adjustment to lease income. If the collectability assessment changes to not probable after the commencement date, lease income is reversed to the extent that the lease payments that have been collected from the lessee are less than the lease income recognized to date. Changes to the collectability of operating leases are recorded as adjustments to lease income in the consolidated statement of operations. During the years ended December 31, 2019 , 2018 and 2017 , Brookfield DTLA recorded provisions for doubtful accounts of $165 thousand and $190 thousand , and a recovery of doubtful accounts of $7 thousand , respectively. The Company wrote off rents, deferred rents and other receivables totaling $478 thousand during the year ended December 31, 2019 . Intangibles Assets and Liabilities, Net— Brookfield DTLA evaluates each acquisition of real estate to determine whether the integrated set of assets and activities meets the definition of a business and needs to be accounted for as a business combination. An acquisition of an integrated set of assets and activities that does not meet the definition of a business is accounted for as an asset acquisition. For an acquisition of real estate that is accounting for as a business combination, the Company allocates the acquisition consideration (excluding acquisition costs) to the assets acquired, liabilities assumed, noncontrolling interests, and any previously existing ownership interests at fair value as of the acquisition date. Acquired assets include tangible real estate assets consisting primarily of land, buildings, and tenant improvements, as well as identifiable intangible assets and liabilities, including acquired above- and below-market leases, in-place leases and tenant relationships. The principal valuation technique employed by Brookfield DTLA in determining the fair value of identified assets acquired and liabilities assumed is the income approach, which is then compared to the cost approach. Tangible values for investments in real estate are calculated based on replacement costs for like-type quality assets. Above- and below-market lease values are determined by comparing in-place rents with current market rents. In‑place lease amounts are determined by calculating the potential lost revenue during the replacement of the current leases in place. Leasing commissions and legal/marketing fees are determined based upon market allowances pro-rated over the remaining lease terms. Loans assumed in an acquisition are analyzed using current market terms for similar debt. The value of the acquired above- and below-market leases are amortized and recorded as either a decrease (in the case of above-market leases) or an increase (in the case of below-market leases) to lease income in the consolidated statement of operations over the remaining term of the associated lease. The value of tenant relationships is amortized over the expected term of the relationship, which includes an estimated probability of lease renewal. The value of in-place leases is amortized as an expense over the remaining life of the leases. Amortization of tenant relationships and in‑place leases is included as part of depreciation and amortization in the consolidated statement of operations. Deferred Charges, Net— Deferred charges mainly include initial direct costs, primarily commissions related to the leasing of the Company’s office properties, are presented as deferred charges in the consolidated balance sheet net of accumulated amortization totaling $43.6 million and $50.3 million as of December 31, 2019 and 2018 , respectively. All leasing commissions paid for new or renewed leases are capitalized and deferred. Deferred leasing costs are amortized on a straight‑line basis over the initial fixed terms of the related leases as part of depreciation and amortization expense in the consolidated statement of operations. Costs to negotiate or arrange a lease, regardless of its outcome, such as fixed employee compensation, tax or legal advice to negotiate lease terms, and lessor costs related to advertising or soliciting potential tenants, are expensed as incurred. Due From/To Affiliates— Amounts due from/to affiliates consist of related party receivables from and payables due to affiliates of BPY and BAM, primarily related to lease income and fees for property and asset management and other services. See Note 15—“Related Party Transactions.” Prepaid and Other Assets, Net— Prepaid and other assets, net include prepaid insurance, real estate taxes and interest, fair value of derivative financial instruments and refundable deposits. Secured Debt, Net— Debt secured by our properties are presented in the consolidated balance sheet net of unamortized debt financing costs. Debt financing costs and discounts totaling $5.3 million , $9.6 million , and $6.4 million were amortized during the years ended December 31, 2019 , 2018 and 2017 , respectively, over the terms of the related loans using the effective interest method and are included as part of interest expense in the consolidated statements of operations. Any unamortized amounts remaining upon the early repayment of debt are written off, and the related costs and accumulated amortization are removed from the consolidated balance sheet. Mezzanine Equity— Mezzanine equity in the consolidated balance sheet 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 December 31, 2019 and 2018 . Adjustments to increase or decrease the carrying amount to redemption value are recorded in the consolidated statement of operations as redemption measurement adjustments. Revenue Recognition— Lease Income— Brookfield DTLA’s lease income primarily represents revenue related to agreements for rental of our investments in real estate, subject to ASC Topic 842, Leases . All of the leases in which the Company is the lessor are classified as operating leases. The Company’s leases do not have guarantees of residual value of the underlying assets. We manage risk associated with the residual value of our leased assets by carefully selecting our tenants and monitoring their credit quality throughout their respective lease terms. Upon the expiration or termination of a lease, the Company often has the ability to re-lease the space with an existing tenant or to a new tenant within a reasonable amount of time. None of our tenants accounted for more than 10% of our lease income for the year ended December 31, 2019 . As of December 31, 2019 , Brookfield DTLA has six Class A office properties and one retail center aggregating 7.6 million net building rentable square feet located in the LACBD. We are susceptible to adverse developments in the markets for office space, particularly in Southern California. Such adverse developments could include oversupply of or reduced demand for office space; declines in property values; business layoffs, downsizings, relocations or industry slowdowns affecting tenants of the Company’s properties; changing demographics; increased telecommuting; terrorist targeting of or acts of war against high-rise structures; infrastructure quality; California state budgetary constraints and priorities; increases in real estate and other taxes; costs of complying with state, local and federal government regulations or increased regulation and other factors. The Company’s lease income is comprised of variable payments including fixed and contingent rental payments and tenant recoveries. Fixed contractual payments from the Company’s leases are recognized on a straight-line basis over the terms of the respective leases. This means that, with respect to a particular lease, actual amounts billed in accordance with the lease during any given period may be higher or lower than the amount of lease income recognized during the period. Straight-line rental revenue is commenced when the customer assumes control of the leased premises. During the years ended December 31, 2019 , 2018 and 2017 , the Company recorded straight-line rental revenue totaling $10.1 million , $11.4 million and $11.2 million , respectively, as part of lease income in the consolidated statements of operations. Certain leases with retail tenants also provide for the payment by the lessee of additional rent based on a percentage of the tenant’s sales. Percentage rents are recognized as lease income in the consolidated statement of operations only after the tenant sales thresholds have been achieved. See Note 16—“Future Minimum Base Rents.” Tenant recoveries, including reimbursements of utilities, repairs and maintenance, common area expenses, real estate taxes and insurance, and other operating expenses, are recognized as part of lease income in the consolidated statement of operations in the period when the applicable expenses are incurred and the tenant’s obligation to reimburse us arises. Some of the Company’s leases have termination options that allow the tenant to terminate the lease prior to the end of the lease term under certain circumstances. Termination options generally become effective half way or further into the original lease term and require advance notification from the tenant and payment of a termination fee that reimburses the Company for a portion of the remaining rent under the original lease term and the undepreciated lease inception costs such as commissions, tenant improvements and lease incentives. Termination fees are recognized as part of lease income in the consolidated statement of operations at the later of when the tenant has vacated the space or the lease has expired, a fully executed lease termination agreement has been delivered to the Company, the amount of the fee is determinable and collectability of the fee is reasonably assured. Parking Revenue— Parking revenue is recognized in accordance with Topic 606, Revenue from Contracts with Customers , when the services are provided and the performance obligations are satisfied, which normally occurs at a point in time. 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 makes distributions to its stockholders, if any, that generally equal or exceed its taxable income. Brookfield DTLA has elected to treat certain of its subsidiaries as taxable REIT subsidiaries (“ TRS ”). A TRS is permitted to engage in activities that a REIT cannot engage in directly, such as performing non‑customary services for the Company’s tenants, holding assets that the Company cannot hold directly and conducting certain affiliate transactions. A TRS is subject to both federal and state income taxes. The Company’s various TRS did not have significant tax provisions during the years ended December 31, 2019 , 2018 and 2017 or deferred income tax items for the years ended December 31, 2019 and 2018 . As of December 31, 2019 and 2018 , Brookfield DTLA had net operating loss carryforwards (“ NOLs ”) totaling $290.2 million and $281.5 million , respectively. The NOLs generated prior to January 1, 2018 will begin to expire in 2033 , while NOLs generated in tax years beginning January 1, 2018 or later have an indefinite carryforward period. 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 has no unrecognized tax benefits as of December 31, 2019 and 2018 , and does not expect its unrecognized tax benefits balance to change during the next 12 months. As of December 31, 2019 , Brookfield DTLA’s 2015, 2016, 2017 and 2018 tax years remain open under the normal statute of limitations and may be subject to examination by federal, state and local authorities. Derivative Financial Instruments— Brookfield DTLA uses interest rate swap and cap contracts to manage risk from fluctuations in interest rates. The Company believes these contracts are with counterparties who are creditworthy financial institutions. At the inception of the contracts, Brookfield DTLA designates its interest rate swap contracts as cash flow hedges and documents the relationship of the hedge to the underlying transaction. Hedge effectiveness is assessed at inception and throughout the life of the hedge to ensure the hedge qualifies for hedge accounting. Changes in fair value associated with hedge ineffectiveness, if any, are recorded as part of interest expense in the consolidated statement of operations. Changes in fair value of cash flow hedge derivative financial instruments are deferred and recorded as part of accumulated other comprehensive loss in the consolidated statement of stockholders’ deficit until the underlying transaction affects earnings. In the event that an anticipated transaction is no longer likely to occur, the Company recognizes the change in fair value of the derivative financial instrument in the consolidated statement of operations in the period the determination is made. Interest rate swap assets are included in prepaid and other assets, net and interest rate swap liabilities are included in accounts payable and other liabilities in the consolidated balance sheet. Additionally, Brookfield DTLA uses interest rate cap contracts to limit impact of changes in the LIBOR rate on certain of its debt. The Company does not use hedge accounting for these contracts, and as such, changes in fair value are recorded in the period of change as part of other expense in the consolidated statement of operations. Other Financial Instruments— Brookfield DTLA’s other financial instruments that are exposed to concentrations of credit risk consist primarily of cash and accounts receivable. Management routinely assesses the financial strength of its tenants and, as a consequence, believes that its accounts receivable credit risk exposure is limited. Brookfield DTLA places its temporary cash investments with federally insured institutions. Cash balances with any one institution may at times be in excess of the federally insured limits. Fair Value Measurements— Fair value is defined as the price that would be received to sell an asset or the price that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date and, in many cases, requires management to make a number of significant judgments. Based on the observable inputs used in the valuation techniques, Brookfield DTLA classifies its assets and liabilities measured and disclosed at fair value in accordance with a three-level hierarchy (i.e., Level 1, Level 2 and Level 3) established under ASC 820, Fair Value Measurements . Brookfield DTLA records certain financial instruments, such as interest rate swap and cap contracts, at fair value on a recurring basis. Certain financial instruments, such as accounts receivable, are not carried at fair value each period but may require nonrecurring fair value adjustments due to write-downs of individual assets. The fair value of Brookfield DTLA’s derivative financial instruments 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, which management considers to be Level 2 inputs. The Company has incorporated credit valuation adjustments to appropriately reflect both our own and the respective counterparty’s non-performance risk in the fair value measurements. See Note 13—“Fair Value Measurements.” The Company estimates the fair value of its debt by calculating the credit-adjusted present value of principal and interest payments for each loan. The calculation incorporates observable market interest rates, which management considers to be Level 2 inputs, assumes that each loan will be outstanding until maturity, and excludes any options to extend the maturity date of the loan available per the terms of the loan agreement, if any. See Note 14—“Financial Instruments.” Recent Accounting Pronouncements Accounting Pronouncements Adopted in 2019 Please refer to Note 3—“Leases” for a discussion of our adoption of Topic 842, Leases , on January 1, 2019 . In August 2017, the Financial Accounting Standards Board (“ FASB ”) issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. This update introduced amendments to Topic 815, Derivatives and Hedging, intended to make targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. The objective of this 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. Brookfield DTLA adopted the guidance in ASU 2017-12 on January 1, 2019 . The adoption of this guidance did not have a material impact on Brookfield DTLA’s consolidated financial statements. In October 2018, the FASB issued ASU 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (“ SOFR ”) Overnight Index Swap (“ OIS ”) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes . ASU 2018-16 amends |
