Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION Brookfield Property REIT Inc. (referred to herein as "BPR or the "Company"), formerly known as GGP Inc. ("GGP"), a Delaware corporation, was organized in July 2010 and is an externally managed real estate investment trust ("REIT"). On March 26, 2018, GGP and Brookfield Property Partners L.P. ("BPY") entered into an agreement and plan of merger (as amended by the amendment thereto dated June 25, 2018, the "Merger Agreement") pursuant to which BPY would acquire all of the shares of GGP common stock, par value $0.01 per share, that BPY and its affiliates did not already own through a series of transactions (collectively, the "BPY Transaction"), including, among other things, the exchange of all shares of GGP common stock owned by certain affiliates of BPY and any subsidiary of GGP for a newly authorized series of preferred stock of GGP designated Series B Preferred Stock (the "Class B Exchange") and the payment of a special dividend payable to certain holders of record of GGP common stock pursuant to the terms of the Merger Agreement (the "Pre-Closing Dividend"). On July 26, 2018, GGP obtained the requisite stockholder approval for the BPY Transaction at a special meeting of GGP stockholders. Therefore, on July 27, 2018, GGP effected the Class B Exchange by exchanging shares of GGP common stock owned by certain affiliates of BPY and any subsidiary of GGP into Series B Preferred Stock. On August 27, 2018, pursuant to the Merger Agreement, the Pre-Closing Dividend and consideration was paid to all holders of record of GGP common stock (not including holders of GGP restricted stock, but including certain holders of GGP options who were deemed stockholders) on July 27, 2018 following the Class B Exchange. The Pre-Closing Dividend and consideration provided for the distribution of up to $23.50 in cash or a choice of either one BPY limited partnership unit ("BPY unit") or one share of newly authorized Class A Stock of BPR, par value $0.01 per share ("Class A Stock"), subject to proration in each case, based on an aggregate cash consideration amount of $9.25 billion . Pursuant to the Merger Agreement, on August 27, 2018, GGP’s certificate of incorporation was amended and restated (the "Charter Amendments") to, among other things, change the Company's name to Brookfield Property REIT Inc., authorize the issuance of Class A Stock, Class B-1 Stock, par value $0.01 per share ("Class B-1 Stock") and Class C Stock, par value $0.01 per share ("Class C Stock") and to provide the terms governing the Series B Preferred Stock and Class B-1 Stock (collectively, "Class B Stock"). In addition, the Company amended and restated its bylaws (the "Bylaws Amendments") and the agreement of limited partnership of GGP Operating Partnership, LP ("GGPOP"), a subsidiary of GGP that was renamed BPR OP, LP ("BPROP") (the "Amended BPR OP Partnership Agreement"). The Charter Amendments superseded the certificate of designations authorizing the Company's Series B Preferred stock, such that the Series B Preferred Stock remains outstanding but is referred to following the Charter Amendments as Class B Stock, having the rights, powers, preferences and other terms given to Class B Stock in the Charter Amendments. Each share of Class A Stock was structured to provide its holder with an economic return that is equivalent to that of a BPY unit, including rights to identical distributions. Subsequent to the BPY Transaction, Class A stockholders have the right to exchange all or a portion of their Class A Stock for cash at a price equal to the value of an equivalent number of BPY units, subject to adjustment in the event of certain dilutive or other capital events by BPY or BPR. BPY, has the option, but not the obligation, to settle any exchange requests by exchanging each share of Class A Stock for one BPY unit. All dividends to holders of Class A Stock will be paid prior and in preference to any dividends or distributions on the Class B Stock or Class C Stock and will be fully declared and paid before any dividends are declared and paid or any other distributions are made on any Class B Stock or Class C Stock. The holders of Class A Stock shall not be entitled to any dividends from BPR other than the Class A dividend. Except as otherwise expressly provided in the Charter Amendments or as required by law, the holders of Class A Stock, Class B Stock and Class C Stock will vote together and not as separate classes. The holders of shares of each of Class B Stock and Class C Stock will be entitled to one vote for each share thereof held at the record date for the determination of stockholders entitled to vote on any matter. The holders of shares of Class A Stock will be entitled to one vote for each share thereof held at the record date for the determination of stockholders entitled to vote on any matter, except that holders of shares of Class A Stock will not be entitled to vote (i) on a liquidation or dissolution or conversion of the Class A Stock in connection with a market capitalization liquidation event (as described in the Charter Amendments), or (ii) to reduce the voting power of the Class B Stock or Class C Stock. BPR is an indirect subsidiary of BPY, one of the world's largest commercial real estate companies. Although the BPY Transaction resulted in a change of control of the Company, BPR remains a reporting entity. Accordingly, the Company accounted for the BPY Transaction as an equity recapitalization transaction. The BPY Transaction resulted in the consummation of a series of recapitalization and financing transactions (see Note 6 ) and joint venture asset sales (see Note 3 ). In these notes, the terms "we", "us" and "our" refer to BPR and its subsidiaries. BPR, through its subsidiaries and affiliates, is an owner and operator of retail properties. As of December 31, 2019 , we are the owner, either entirely or with joint venture partners, of 122 retail properties. Substantially all of our business is conducted through BPROP, which we sometimes refer to herein as the Operating Partnership and its subsidiaries. As of December 31, 2019 , BPR held approximately 99% of the common equity of BPROP, while the remaining 1% was held by limited partners and certain previous contributors of properties to BPROP. In addition to holding ownership interests in various joint ventures, the Operating Partnership generally conducts its operations through BPR REIT Services LLC. ("BPRRS"), Brookfield Properties Retail Inc. ("BPRI") and General Growth Management, Inc. ("GGMI"). Each of GGMI and BPRI is a taxable REIT subsidiary ("TRS"), which provides real estate management and leasing fees, development fees, financing fees for other ancillary services for a majority of our Unconsolidated Real Estate Affiliates (defined below) and for substantially all of our Consolidated Properties (defined below). BPRI also serves as a contractor to GGMI for these services. BPRRS generally provides financial, accounting, tax, legal, development, and other services to our Consolidated Properties. We refer to our ownership interests in properties in which we own a majority or controlling interest and are consolidated under accounting principles generally accepted in the United States of America ("GAAP") as the "Consolidated Properties." We also own interests in certain properties through joint venture entities in which we own a noncontrolling interest ("Unconsolidated Real Estate Affiliates") and we refer to those properties as the "Unconsolidated Properties".

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation and Basis of Presentation The accompanying consolidated financial statements include the accounts of BPR, our subsidiaries and joint ventures in which we have a controlling interest. For consolidated joint ventures, the noncontrolling partner's share of the assets, liabilities and operations of the joint ventures (generally computed as the joint venture partner's ownership percentage) is included in noncontrolling interests in consolidated real estate affiliates as permanent equity of the Company. Intercompany balances and transactions have been eliminated. Noncontrolling interests are included on our Consolidated Balance Sheets related to the Common, Preferred, and LTIP Units of BPROP and are presented either as redeemable noncontrolling interests or as noncontrolling interests in our permanent equity. The Operating Partnership and each of our consolidated joint ventures are variable interest entities as the limited partners do not have substantive kick-out rights or substantive participating rights. However, as the Company holds a majority voting interest in the Operating Partnership and our consolidated joint ventures, it qualifies for the exemption from providing certain of the disclosure requirements associated with variable interest entities. We operate in a single reportable segment, which includes the operation, development and management of retail and other rental properties. Our portfolio is targeted to a range of market sizes and consumer tastes. Each of our operating properties is considered a separate operating segment, as each property earns revenues and incurs expenses, individual property operating results are reviewed and discrete financial information is available. The Company's chief operating decision maker is comprised of a team of several members of executive management who use property operations in assessing segment operating performance. We do not distinguish or group our consolidated operations based on geography, size or type for purposes of making property operating decisions. Our operating properties have similar economic characteristics and provide similar products and services to our tenants. There are no individual operating segments that are greater than 10% of combined revenue or combined assets. When assessing segment operating performance, certain non-cash and non-comparable items such as straight-line rent, depreciation expense and intangible asset and liability amortization, are excluded from property operations, which are a result of our emergence, acquisition accounting and other capital contribution or restructuring events. Further, all material operations are within the United States and no customer or tenant comprises more than 10% of consolidated revenues. As a result, the Company's operating properties are aggregated into a single reportable segment. Properties Real estate assets are stated at cost less any provisions for impairments. Expenditures for significant betterments and improvements are capitalized. Maintenance and repairs are charged to expense when incurred. Construction and improvement costs incurred in connection with the development of new properties or the redevelopment of existing properties are capitalized. Real estate taxes, interest costs, and initial direct costs associated with leasing and development overhead incurred during construction periods are capitalized. Capitalization is based on qualified expenditures and interest rates. Capitalized real estate taxes, interest costs, and initial direct costs associated with leasing and development overhead are amortized over lives which are consistent with the related assets. Pre-development costs, which generally include legal and professional fees and other third-party costs directly related to the construction assets, are capitalized as part of the property being developed. In the event a development is no longer deemed to be probable of occurring, the capitalized costs are expensed (see also our impairment policies in this note below). We periodically review the estimated useful lives of our properties, and may adjust them as necessary. The estimated useful lives of our properties range from 10 - 45 years. Depreciation or amortization expense is computed using the straight-line method based upon the following estimated useful lives: Years Buildings and improvements 10 - 45 Equipment and fixtures 3 - 20 Tenant improvements Shorter of useful life or applicable lease term Reclassifications The reclassifications presented in the table below are the result of the Company's adoption of the new accounting guidance for lease accounting, Accounting Standards Codification (ASC) 842, Leases, ("ASC 842" or "the new leasing standard") on January 1, 2019. As part of that adoption, the Company elected the available practical expedient, for all classes of assets, not to separate lease components in contracts from the nonlease components in those contracts, when recording revenues associated with operating leases where it is the lessor. Since the lease component is the predominant component under the Company's leases, combined revenues from both the lease and nonlease components are accounted for in accordance with ASC 842. Components of revenue that were previously reported as minimum rents, tenant recoveries, and overage rents have been combined and reported as rental revenues on the Consolidated Statements of Operations and Comprehensive Income. The presentation and disclosure of rental revenues have been adjusted to reflect these changes for the year ended December 31, 2019. Total revenues of the Company are unchanged by this reclassification. Refer to Note 7 for further information. Year Ended December 31, 2018 Year Ended December 31, 2017 As Originally Reported As Reclassified As Originally Reported As Reclassified Minimum rents $ 1,297,945 $ — $ 1,455,039 $ — Tenant recoveries 540,376 — 643,607 — Overage rent 29,659 — 34,874 — Total rental revenues $ — $ 1,867,980 $ — $ 2,133,520 Acquisitions of Operating Properties ( Note 3 ) Acquisitions of properties are typically accounted for as acquisitions of assets rather than acquisitions of a business. Accordingly, the results of operations of acquired properties have been included in the results of operations from the respective dates of acquisition and acquisition costs are capitalized. Estimates of future cash flows and other valuation techniques are used to allocate the purchase price of acquired property between land, buildings and improvements, equipment, assumed debt liabilities and identifiable intangible assets and liabilities such as amounts related to in-place tenant leases, acquired above and below-market tenant and ground leases, and tenant relationships. The fair values of tangible assets are determined on an "if vacant" basis. The "if vacant" fair value is allocated to land, where applicable, buildings, equipment and tenant improvements based on comparable sales and other relevant information with respect to the property. Specifically, the "if vacant" value of the buildings and equipment was calculated using a cost approach utilizing published guidelines for current replacement cost or actual construction costs for similar, recently developed properties; and an income approach. Assumptions used in the income approach to the value of buildings include: capitalization and discount rates, lease-up time, market rents, make ready costs, land value, and site improvement value. The estimated fair value of in-place tenant leases includes lease origination costs (the costs we would have incurred to lease the property to the current occupancy level of the property) and the lost revenues during the period necessary to lease-up from vacant to the current occupancy level. Such estimates include the fair value of leasing commissions, legal costs and tenant coordination costs that would be incurred to lease the property to this occupancy level. Additionally, we evaluate the time period over which such occupancy level would be achieved and include an estimate of the net operating costs (primarily real estate taxes, insurance and utilities) incurred during the lease-up period, which generally ranges up to one year . The fair value of acquired in-place tenant leases is included in the balance of buildings and equipment and amortized over the remaining lease term for each tenant. Identifiable intangible assets and liabilities are calculated for above-market and below-market tenant and ground leases where we are either the lessor or the lessee. The difference between the contractual rental rates and our estimate of market rental rates is measured over a period equal to the remaining non-cancelable term of the leases, including significantly below-market renewal options for which exercise of the renewal option appears to be reasonably assured. The remaining term of leases with renewal options at terms significantly below market reflect the assumed exercise of such below-market renewal options and assume the amortization period would coincide with the extended lease term. The gross asset balances of the in-place value of tenant leases are included in buildings and equipment in our Consolidated Balance Sheets. Gross Asset Accumulated Amortization Net Carrying Amount As of December 31, 2019 Tenant leases: In-place value $ 311,838 $ (72,658 ) $ 239,180 As of December 31, 2018 Tenant leases: In-place value $ 188,140 $ (86,510 ) $ 101,630 The above-market tenant leases are included in prepaid expenses and other assets ( Note 15 ); the below-market tenant leases are included in accounts payable and accrued expenses ( Note 16 ) in our Consolidated Balance Sheets. Amortization/accretion of all intangibles, including the intangibles in Note 15 and Note 16 , had the following effects on our income from continuing operations: Year Ended December 31, 2019 2018 2017 Amortization/accretion effect on continuing operations $ (14,101 ) $ (48,655 ) $ (74,802 ) Future amortization/accretion of all intangibles, including the intangibles in Note 15 and Note 16 is estimated to decrease results from continuing operations as follows: Year Amount 2020 $ 41,771 2021 36,947 2022 36,195 2023 35,912 2024 35,202 Investments in Unconsolidated Real Estate Affiliates ( Note 5 ) We account for investments in joint ventures where we own a non-controlling joint interest using either the equity method or the cost method. If we have significant influence but not control over the investment, we utilize the equity method. If we have neither control nor significant influence, we utilize the cost method. Under the equity method, the cost of our investment is adjusted for our share of the earnings of such Unconsolidated Real Estate Affiliates from the date of acquisition, increased by our contributions and reduced by distributions received. Under the cost method, the cost of our investment is not adjusted for our share of the earnings of such Unconsolidated Real Estate Affiliates from the date of acquisition and distributions are treated as earnings when received. To determine the method of accounting for partially owned joint ventures, we evaluate the characteristics of associated entities and determine whether an entity is a variable interest entity ("VIE"). A limited partnership or other similar entity is considered a VIE unless a simple majority of limited partners (excluding limited partners that are under common control with the general partner) have substantive kick-out rights or participating rights. If an entity is determined to be a VIE, we determine which party is the primary beneficiary by analyzing whether we have both the power to direct the entity's significant economic activities and the obligation to absorb potentially significant losses or receive potentially significant benefits. Significant judgments and assumptions inherent in this analysis include the nature of the entity's operations, future cash flow projections, the entity's financing and capital structure, and contractual relationship and terms. Primary risks associated with our VIEs include the potential of funding the entities' debt obligations or making additional contributions to fund the entities' operations. Generally, the operating agreements with respect to our Unconsolidated Real Estate Affiliates provide that assets, liabilities and funding obligations are shared in accordance with our ownership percentages. Therefore, we generally also share in the profit and losses, cash flows and other matters relating to our Unconsolidated Real Estate Affiliates in accordance with our respective ownership percentages. Except for Retained Debt (as described in Note 5 ), differences between the carrying amount of our investment in the Unconsolidated Real Estate Affiliates and our share of the underlying equity of our Unconsolidated Real Estate Affiliates are typically amortized over lives ranging from 5 to 45 years. When cumulative distributions exceed our investment in the joint venture, the investment is reported as a liability in our consolidated financial statements. The liability is limited to our maximum potential obligation to fund contractual obligations, including recourse related to certain debt obligations. Partially owned joint ventures over which we have controlling financial interest are consolidated in our consolidated financial statements. In determining if we have a controlling financial interest, we consider factors such as ownership interest, authority to make decisions, kick-out rights and substantive participating rights. Partially owned joint ventures where we do not have a controlling financial interest, but have the ability to exercise significant influence, are accounted for using the equity method. To the extent that we contribute assets to a joint venture accounted for using the equity method, our investment in the joint venture is recorded at the fair value of the consideration of the assets that were contributed to the joint venture. We will recognize gains and losses on the contribution of our real estate to joint ventures, relating to our entire investment in the property, to the extent the buyer is independent of the Company, the collection of the sales price is reasonably assured, and we will not be required to support the operations of the property or its related obligations to an extent greater than our proportionate interest. The combined summarized financial information of unconsolidated joint ventures is disclosed in Note 5 to the Consolidated Financial Statements. We continually analyze and assess reconsideration events, including changes in the factors mentioned above, to determine if the consolidation treatment remains appropriate. Decisions regarding consolidation of partially owned entities frequently require significant judgment by our management. Cash and Cash Equivalents Highly-liquid investments with initial maturities of three months or less are classified as cash equivalents, excluding amounts restricted by certain lender and other agreements. Deferred Expenses Deferred expenses primarily consist of leasing commissions and related costs and are amortized using the straight-line method over the life of the leases. Revenue Recognition and Related Matters Accounting for real estate sales distinguishes between sales to a customer or non-customer for purposes of revenue recognition. Once we, as the seller, determine that we have a contract, we will identify each distinct non-financial asset promised to the counter-party and whether the counter-party obtains control and transfers risks and rewards of ownership of each non-financial asset to determine if we should derecognize the asset. Notes receivable are evaluated for impairment at least quarterly. Impairment occurs when it is deemed probable that we will not be able to collect all amounts due according to the contractual terms of the loan. If a loan is considered to be impaired, we record an allowance through the provision for loan losses to reduce the carrying value of the loan to the present value of expected future cash flows discounted at the loan’s contractual effective rate or the fair value of the collateral, if repayment is expected solely from the collateral. We provide an allowance for doubtful accounts against the portion of accounts receivable, net including straight-line rents, which is estimated to be uncollectible, which includes a portfolio based reserve and reserves for specific disputed amounts. Such allowances are reviewed each period based upon our recovery experience and the specific facts of each outstanding amount. The following table summarizes the changes in allowance for doubtful accounts: 2019 2018 2017 Balance as of January 1, $ 19,657 $ 19,457 $ 17,883 Provision for doubtful accounts (1) 15,728 14,309 13,594 Write-offs (7,560 ) (14,109 ) (12,020 ) Balance as of December 31, $ 27,825 $ 19,657 $ 19,457 _______________________________________________________________________________ (1) Excludes recoveries of $4.7 million , $2.2 million and $2.9 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. Leases ( Note 7 ) We have entered into lease arrangements for the land and buildings at certain properties, as well as for the use of office space in Chicago, Illinois. We account for leases under ASC 842, Leases ("the new leasing standard"). We elected to use the "package of practical expedients", as discussed below, which allowed us not to reassess under the new leasing standard prior conclusions about lease identification, lease classification, and initial direct costs. We elected to recast prior-period comparative information presented in our Consolidated Statements of Operations and Comprehensive Income related to rental revenues. The new leasing standard requires lessees to record a right-of-use ("ROU") asset and a related lease liability for the rights and obligations associated with all lessee leases. ASC 842 also modified the lease classification criteria through the elimination of "bright-line" tests, the removal of historical real estate specific lease provisions, and changes to lessor accounting to align with the new revenue recognition standard ASC 606, Revenue from Contracts with Customers . On the adoption date, we recognized lease liabilities of $73.4 million and ROU assets of $118.9 million for operating leases of Consolidated Properties for which we are the lessee included in accounts payable and accrued expenses and prepaid expenses and other assets, respectively, on the Consolidated Balance Sheet and there was no cumulative effect on retained earnings. In order to determine the lease liabilities recognized upon adoption, we discounted the remaining lease payments using our incremental borrowing rates ("IBR") at January 1, 2019. The weighted average rate applied was 7.36% . The ROU asset balance was initially measured as the lease liability amount adjusted by the amount of prepaid or accrued lease payments, deferred straight-line lease liabilities, and intangible ground lease assets and liabilities relating to leases recognized on our Consolidated Balance Sheet as of December 31, 2018. In transition, an adjustment of $45.4 million was made to the ROU asset balance to derecognize $52.8 million of below-market ground lease intangible assets (within prepaid expenses and other assets) and $7.4 million of accrued straight-line rent (within accounts payable and accrued expenses) which are now part of the total ROU assets previously recorded on our Consolidated Balance Sheet. In addition to the "package of practical expedients", we elected to use the following additional practical expedients permitted by the new leasing standard: • The transition practical expedient that allows us to carry forward our historical accounting treatment for land easements on existing agreements. • The short-term lease election that allows a lessee not to apply the balance sheet recognition requirements to leases with a term of 12 months or less; lease payments associated with these leases are recognized on a straight-line basis as an expense over the lease term and are not material. • The practical expedient which allows a lessee to not separate lease and non-lease components. We have elected to apply this election to all classes of underlying assets. • The Company did not elect to apply the practical expedients related to hindsight or assessing impairment of ROU assets. Lessee arrangements To account for leases for which we are the lessee under the new leasing standard, contracts must be analyzed upon inception to determine if the arrangement is, or contains, a lease. A lease conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Lease classification tests and measurement procedures are performed at the lease commencement date. Differences in lease classification will affect only the pattern and classification of expense recognition in our Consolidated Statements of Operations and Comprehensive Income. The lease liability is initially measured as the present value of the lease payments over the lease term, discounted using the interest rate implicit in the lease, if that rate is readily determinable; otherwise, the lessee’s incremental borrowing rate is used. The lease liability balance is subsequently amortized using the effective interest method. The incremental borrowing rate is determined using an approach based on the rate of interest that the lessee would pay to borrow on a collateralized basis over a similar term at an amount equal to the lease payments in a similar economic environment. We utilized a market-based approach to estimate the IBR for each individual lease. Therefore, we utilized different data sets to estimate base IBRs via an analysis of (i) yields on outstanding public debt of BPR, as well as comparable companies, (ii) observable mortgage rates, and (iii) unlevered property yields and discount rates. We then applied adjustments to account for considerations related to (i) term and (ii) security that may not be fully incorporated by the aforementioned data sets. Based on individual characteristics of each lease, we selected an IBR taking into consideration how each data approach and adjustments thereto incorporate term, currency and security. The lease term is the noncancelable period of the lease, and includes any renewal and termination options we are reasonably certain to exercise. The reasonably certain threshold is evaluated at lease commencement and is typically met if substantial economic incentives or termination penalties are identified. Lease payments measured at the commencement date include fixed payments, in-substance fixed payments, variable lease payments dependent on a rate or index (using the index or rate in effect at lease commencement), any purchase option the lessee is reasonably certain to exercise, and payments of penalties for terminating the lease if the lease term reflects the lessee exercising the termination option. Fully variable lease payments without an in-substance fixed component are not included in the measurement of the lease liability and are recognized in the period in which the underlying contingency is resolved. The lease liability is remeasured when the contract is modified, upon the resolution of a contingency such that variable payments become fixed or if our assessment of exercising an extension, termination or purchase option changes. Once remeasured, an adjustment is made to the ROU asset. However, if the carrying amount of the right-of-use asset is reduced to zero, any remaining amount of the remeasurement is recognized in earnings. The ROU asset balance is initially measured as the lease liability amount, adjusted for any lease payments made prior to the commencement date, initial direct costs, estimated costs to dismantle, remove, or restore the underlying asset and incentives received. Our current lessee lease portfolio is comprised primarily of operating leases. If we enter into a finance lease, the new leasing standard requires us to initially recognize and measure these leases using the same method as described above for operating leases. Subsequent to initial recognition, each lease payment would be allocated between interest expense and a reduction of the lease liability. This expense would be recognized over the lease term using the interest method to produce a constant periodic rate of interest on the remaining balance of the liability for each period and would be included in interest expense in our Consolidated Statements of Operations and Comprehensive Income. The ROU asset would be amortized on a straight-line basis over the lease term, with depreciation recorded in depreciation and amortization in our Consolidated Statements of Operations and Comprehensive Income. The ROU assets in our operating leases are evaluated for impairment in a manner similar to our operating properties, as described below under "Impairment". Lessor arrangements At the inception of a new lease arrangement, including new leases that arise from amendments, we assess the terms and conditions to determine the proper lease classification. When the terms of a lease effectively transfer control of the underlying asset, the lease is classified as a sales-type lease. When a lease does not effectively transfer control of the underlying asset to the lessee, but we obtain a guarantee for the value of the asset from a third party, we classify the lease as a direct financing lease. All other leases are classified as operating leases. Control of the underlying asset is transferred to the lessee if any of the following criteria are met: (i) transfer of ownership to the lessee prior to or shortly after the end of the lease term, (ii) lessee has an option to purchase the underlying property that the lessee is reasonably certain to exercise, (iii) the lease term is for the major part of the underlying property’s remaining economic life, (iv) the present value of the sum of lease payments and any residual value guaranteed by the lessee that is not already reflected in the lease payments is equal to or exceeds substantially all of the fair value of the leased property or (v) the underlying property is of such a specialized nature that it is expected to have no alternative use at the end of the lease term. As of December 31, 2019, we do not have any material sales-type or direct financing leases. For operating leases with minimum scheduled rent increases, we recognize rental income on a straight‑line basis, including the effect of any free rent periods, over the lease term when collectability of lease payments (and, if applicable, any amounts necessary to satisfy a residual value guarantee) is probable. Variable lease payments are recognized as rental income in the period when the changes in facts and circumstances on which the variable lease payments are based occur. Variable lease payments include overage rent, which is paid by a tenant when the tenant's sales exceed an agreed upon minimum amount, is recognized once tenant sales exceed contractual tenant lease thresholds and is calculated by multiplying the sales in excess of the minimum amount by a percentage defined in the lease. Our leases also contain provisions for tenants to reimburse us for real estate taxes and insurance, as well as for other property operating expenses, marketing costs, and utilities, which are considered to be non-lease components. These tenant reimbursements are most often established in the leases or in less frequent cases computed based upon a formula. W e have elected the practical expedient to not separate non-lease components from the lease component for all classes of underlying assets and determined that the lease component is the predominant component in the contract; therefore, these recoveries are recognized in a manner similar to minimum rents and variable rents within rental revenues on our Consolidated Statements of Operations and Comprehensive Income. Recognizing rental and related income on a straight-line basis results in a difference in the timing of revenue recognition from what is contractually due from tenants. Straight-line rents are recorded in accounts receivable, net in our Consolidated Balance Sheet. For leases where collectability of the lease payments is probable, we establish a general allowance for doubtful accounts against the portion of accounts receivable, net, including straight-line rents, which is estimated to be uncollectible based on our previous recovery experience. Changes in the general allowance are recognized in rental income on our Consolidated Statements of Operations and Comprehensive Income. If we determine that collectability of the lease payments is not probable, we record a current-period adjustment to rental income to reduce cumulative income recognized since lease commencement to the amount of cash collected from the lessee. Future revenue recognition is limited to amounts paid by the lessee . Generally, a lease is returned to accrual status when all delinquent payments become current under the terms of the lease agreement and collectability of the remaining contractual lease payments is reasonably probable. Rental revenues also includes lease termination income collected from tenants to allow for the tenant to vacate their space prior to their scheduled termination dates, as well as accretion related to above-market and below-market tenant leases on acquired properties and properties that were recorded at fair value at the emergence from bankruptcy. In leasing tenant space, we may provide funding to the lessee through a tenant allowance. To account for a tenant allowance, we determine whether the allowance represents funding for the construction of leasehold improvements and evaluate the control and ownership of such improvements. If we are considered the owner of the leasehold improvements, we capitalize the amount of the tenant allowance and depreciate it over the shorter of the useful life of the leasehold improveme nts or the related lease term. If the tenant allowance represents a payment for a purpose other than funding leasehold improvements, or in the event we are not considered the owner of the leasehold improvements, the allowance is capitalized to deferred expenses and considered to be a lease incentive and is recognized over the lease term as a reduction of rental revenue on a straight-line basis. The following is a summary of amortization of straight-line rent, net amortization/accretion related to above-market and below-market tenant leases and termination income, which is included in rental revenues: Year Ended December 31, 2019 2018 2017 Amortization of straight-line rent $ 8,488 $ (2,425 ) $ 2,084 Net amortization/accretion of above and below-market tenant leases 22,037 (3,259 ) (23,963 ) Lease termination income 13,235 31,297 29,081 The following is a summary of straight-line rent receivables, which are included in accounts receivable, net in our Consolidated Balance Sheets and are reduced for allowances and amounts doubtful of collection: December 31, 2019 December 31, 2018 Straight-line rent receivables, net $ 142,791 $ 136,007 Deferred expenses The new leasing standard defines initial direct costs as incremental costs of a lease that would not have been incurred if the lease had not been obtained. These initial direct costs (consisting primarily of leasing commissions paid to third parties) are recognized as deferred expenses on our Consolidated Balance Sheet and are amortized using the straight-line method over the life of the leases. Other leasing costs which do not meet the definition of initial direct costs (consisting primarily of internal legal and leasing overhead costs) are expensed as incurred and included in property management and other costs in our Consolidated Statements of Operations and Comprehensive Income. Management Fees and Other Corporate Revenues Management fees and other corporate revenues primarily represent real estate management and leasing fees, development fees, financing fees and fees for other ancillary services performed for the benefit of certain of the Unconsolidated Real Estate Affiliates. Management fees are reported at 100% of the revenue earned from the joint venture in management fees and other corporate revenues on our Consolidated Statements of Operations and Comprehensive Income. Our share of the management fee expense incurred by the Unconsolidated Real Estate Affiliates is reported within equity in income of Unconsolidated Real Estate Affiliates on our Consolidated Statements of Ope

Business Combinations [Abstract]
ACQUISITIONS, SALES AND JOINT VENTURE ACTIVITY	ACQUISITIONS, SALES AND JOINT VENTURE ACTIVITY In connection with the formation of the BPR-FF JV LLC joint venture described below, the Company agreed to use reasonable efforts to cause a transfer to BPR-FF JV LLC of the legal rights it held at Pembroke Lakes Mall at an agreed upon value of $33.8 million . On November 30, 2019, the Company transferred its rights in the Sears Anchor Parcel at Pembroke Lakes Mall to Pembroke Sears Anchor Parcel LLC. At the time of the formation noted above, the legal rights were valued at $35.0 million , resulting in a gain of $1.2 million recorded in other revenues on the Consolidated Statement of Operations and Comprehensive Income for the year ended December 31, 2019. On November 12, 2019, the Company sold its remaining 10% ownership interest in 522 Fifth Avenue in New York City to one of its joint venture partners for $1.0 million . At the time of the sale, the Company's Investment in Unconsolidated Real Estate Affiliate was $7.5 million and the Company recorded a loss of $6.5 million on the sale within Unconsolidated Real Estate Affiliates - gain on investment, net in the Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2019 . On November 1, 2019, the Company (through various indirect subsidiaries) acquired additional ownership interests in four operating properties which had been Unconsolidated Real Estate Affiliates from its former joint venture partners in the properties (affiliates of JPMorgan Chase & Co. ("JPM") and New York State Teachers' Retirement System ("NYSTRS")), bringing its ownership level to 100% and resulting in the Company obtaining control over the entities and consolidating the properties beginning on the transaction date ("JPM Transaction"). In the JPM Transaction, the Company acquired a 65% interest in Park Meadows and Towson Town Center (from JPM and NYSTRS), a 45% interest in Shops at Merrick Park (from JPM), and a 50% interest in Perimeter Mall (from JPM). The Company also transferred its 35% ownership interest in Bridgewater Commons to an affiliate of JPM and NYSTRS. The transaction was accounted for as an asset acquisition for the properties over which the Company obtained control and a sale of the investment in Bridgewater Commons. The transaction consideration for the asset acquisition consisted of cash consideration of $755.7 million and non-cash consideration consisting of the ownership interest in Bridgewater Commons, which the Company valued at $161.9 million , resulting in total transaction consideration for the acquired ownership interests of $917.6 million . The Company recorded a gain of $108.9 million related to the sale of its ownership interest in Bridgewater Commons, which had a carrying value of $53.0 million prior to the JPM Transaction, within Unconsolidated Real Estate Affiliates - gain on investment, net. As a result of the acquisition, in determining the transaction date basis of the newly consolidated properties, the Company determined the fair value of its previously held equity interests of the four properties acquired to be $876.6 million and recorded a gain on changes in control of investment properties of $681.2 million related to its existing 35% interest in Park Meadows and Towson Town Center, 55% interest in Shops at Merrick Park and 50% interest in Perimeter Mall. The fair value of the previously held equity interests was combined with the total transaction consideration for the acquired interests to determine the total cost of the asset acquisition of $1,794.2 million . The table below summarizes the gain from changes in control of investment properties for the JPM Transaction ($ in millions): Fair value of Investment in Unconsolidated Real Estate Affiliates as of change in control $ 876.6 Less: carrying value of Investment in Unconsolidated Real Estate Affiliates 195.4 Gain from changes in control of investment properties and other, net $ 681.2 The following table summarizes the allocation of the purchase price to net assets acquired at the date of acquisition. The allocation was based on the relative fair value of the assets acquired and liabilities assumed ($ in millions): Investment in real estate, including intangible assets and liabilities $ 2,937.7 Fair value of debt held by the acquired properties (1,155.1 ) Net working capital 11.6 Net assets acquired $ 1,794.2 On September 13, 2019, BPR Cumulus LLC (an indirect subsidiary of the Company) purchased 10,000,000 shares of Class A Units in PFC Associates LLC (P.F. Chang's) (par value $0.01 per share) at a price of $1.00 per share, for a $10.0 million total investment, resulting in a 3.2% ownership interest in PF Chang's. P.F. Chang's is a tenant at certain properties for which we receive rental income included in rental revenues on the Consolidated Statements of Operations and Comprehensive Income. The investment is accounted for using the cost method as the Company has neither control nor significant influence over PF Chang's and is included in Investment in Unconsolidated Real Estate Affiliates on the Consolidated Balance Sheets. On August 26, 2019, the Company purchased an additional ownership interest of 49.677% in 730 Fifth Owners, LLC from its joint venture partner resulting in the Company obtaining control of the entity with a total ownership percentage for the Company of 99.677% . The transaction was accounted for as an asset acquisition. The transaction consideration consisted of cash consideration of $153.0 million and satisfaction of notes receivable of $249.5 million from the joint venture partner. Because of the presence of non-cash consideration, the Company determined that the fair value of the net assets acquired was more readily determinable than the fair value of the consideration given, and determined that the aggregate fair value of the joint venture's equity was $808.0 million on the acquisition date, which was allocated to the Company's 99.677% ownership interest for $805.4 million and the joint venture partner's remaining 0.323% non-controlling interest for $2.6 million . Concurrent with this transaction, the joint venture partner repaid $54.7 million of interest on the notes receivable (including amounts that had been annually capitalized onto the outstanding principal balance). The Company recorded a gain on change in control of investment properties of $39.7 million related to the Company's previously held 50% ownership interest. Immediately following this transaction, the Company sold a condominium interest in one unit of the property to an affiliate of the joint venture partner for a gross sales price of $12.6 million and incurred fees of $0.4 million , which resulted in no gain or loss, as the fair value of the condominium interest in the consolidation transaction had been determined to be $12.2 million . The table below summarizes the gain from changes in control of investment properties ($ in millions): Fair value of Investment in Unconsolidated Real Estate Affiliates as of change in control $ 404.0 Less: carrying value of Investment in Unconsolidated Real Estate Affiliates 364.3 Gain from changes in control of investment properties and other, net $ 39.7 The following table summarizes the allocation of the purchase price to net assets acquired at the date of acquisition. The allocation were based on the relative fair value of the assets acquired and liabilities assumed ($ in millions): Investment in real estate, including intangible assets and liabilities $ 1,560.5 Debt held by the joint venture (720.0 ) Net working capital (32.5 ) Net assets acquired $ 808.0 On October 28, 2019, the Company purchased an additional ownership interest of 0.29% in 730 Fifth Owners, LLC from its joint venture partner for $1.8 million . Following this transaction, the Company has a 99.967% ownership interest. On August 19, 2019, the Company sold the SoNo Collection to a newly formed joint venture owned 80.5% by an affiliated fund (which is a related party of the Company) and 19.5% by the Company. The property was contributed to the joint venture at a value of $419.3 million based on project-specific cash costs. This excludes additional costs to complete the project by the joint venture. Prior to obtaining project-specific financing on August 9, 2019, the Company was required under GAAP to capitalize interest on general corporate financings into the cost basis of the project, which resulted in a $38.8 million impairment due to the difference between the project’s GAAP basis and the sale price based upon total project-specific cash costs. Following the transaction, the Company accounts for its non-controlling investment in the SoNo Collection under the equity method of accounting as the Company can exercise significant influence but not control over the joint venture. On December 4, 2019, the joint venture partner contributed $30.0 million and committed to contribute an additional $70.8 million in additional capital to the joint venture, resulting in a dilution of the Company's ownership interest from 19.5% to 12.9% as of December 31, 2019 . The $70.8 million contribution was received on February 7, 2020 ( Note 20 ). On August 12, 2019, the Company completed the sale of the land at the former Sears anchor parcel at Columbia Mall for a gross sales price of $5.0 million , which resulted in a gain on the sale of $3.6 million included in other revenues on the Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2019 . On August 9, 2019, the Company completed the sale of 49.3% of its interest in Authentic Brands Group LLC ("ABG") for a gross sales price of $32.1 million , which resulted in a gain on the sale of $16.8 million included in Unconsolidated Real Estate Affiliates - Gain on Investment on the Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2019. The basis of the remaining 50.7% investment was marked to fair value of $32.1 million in conjunction with the sale transaction noted above, which resulted in an additional gain on sale of $16.8 million directly related to the step up basis in fair value. This gain is recorded in Unconsolidated Real Estate Affiliates - Gain on Investment on the Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2019 . The investment will continue to be accounted for using the cost method as the Company has neither control nor significant influence over ABG and is included in Investment in Unconsolidated Real Estate Affiliates on the Consolidated Balance Sheets. On July 26, 2019, the Company purchased 2,255,503 shares of Series D Preferred Units in Industrious National Management Company LLC at a price of $2.22 per share, for a $5.0 million total investment, resulting in a less than 2.0% ownership interest in Industrious National Management Company LLC. The investment is accounted for using the cost method as the Company has neither control nor significant influence over Industrious National Management Company LLC and is included in Investment in Unconsolidated Real Estate Affiliates on the Consolidated Balance Sheets as of December 31, 2019 . On April 19, 2019, BPR Cumulus LLC (an indirect subsidiary of the Company) purchased 1,250,000 shares of Series F Convertible Preferred Stock in Pinstripes, Inc. (par value $0.01 per share) at a price of $8.00 per share, for a $10.0 million total investment, resulting in a 7.6% ownership interest in Pinstripes, Inc. The investment is accounted for using the cost method as the Company has neither control nor significant influence over Pinstripes, Inc. and is included in Investment in Unconsolidated Real Estate Affiliates on the Consolidated Balance Sheets as of December 31, 2019 . In connection with the formation of the BPR-FF JV LLC joint venture described below, the Company agreed to use reasonable efforts to cause a transfer to BPR-FF JV LLC of the legal rights it held at Coronado Center Mall at an agreed upon value of $53.1 million . On April 9, 2019, the Company transferred its rights in the Sears Anchor Parcel at Coronado Center Mall to Coronado Center LLC. No gain or loss was recognized on the transaction. On January 7, 2019, the Company completed the sale of our 12.0% interest in Bayside Marketplace for a sales price of $42.0 million . Due to cumulative distributions received in excess of its investment, the Company had a liability balance associated with its investment in Bayside Marketplace. Accordingly, the Company recognized a gain of $104.4 million included in Unconsolidated Real Estate Affiliates - gain on investment on our Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2019 . On December 14, 2018, we completed the sale of a 49% joint venture interest in Fashion Place for an initial basis in the partnership of $179.9 million , which resulted in a gain of $294.5 million recognized in gain from changes in control of investment properties and other, net for the year ended December 31, 2018. On November 1, 2018, we conveyed Oak View Mall to the lender in full satisfaction of $74.7 million in outstanding debt. This transaction resulted in a $12.4 million gain on extinguishment of debt for the year ended December 31, 2018 . On August 27, 2018, the BPR-FF JV LLC joint venture was formed with Brookfield Real Estate Partners F LP.

On August 3, 2018, we completed the sale of an anchor box at The Oaks Mall for a gross sales price of $5.0 million , which resulted in a loss of $13.8 million recognized in gains from changes in control of investment properties and other for the year ended December 31, 2018. On July 13, 2018, we completed the sale of the commercial office unit at 685 Fifth Avenue for a gross sales price of $135.0 million . In conjunction with the sale, we paid down a $100.0 million loan and recognized a gain of $11.4 million in gains from changes in control of investment properties and other, net for the year ended December 31, 2018. On January 29, 2018, we completed the sale of a 49.49% joint venture interest in the Sears Box at Oakbrook Center to our joint venture partner for a sales price of $44.7 million , which resulted in a gain of $12.7 million recognized in gains from changes in control of investment properties and other, net for the year ended December 31, 2018. On December 29, 2017, we sold approximately 54% of our interest in Aero IpCo, LLC venture ("IPCO") to ABG for a sales price of $16.6 million , which resulted in a gain of $12.0 million recognized in Unconsolidated Real Estate Affiliates - gain on investment on our Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2017. On March 30, 2018, ABG exercised their call right to purchase the remaining 46% of our original interest in IPCO for a sales price of $13.9 million , which resulted in a gain of $10.4 million recognized in Unconsolidated Real Estate Affiliates - gain on investment on our Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2018. In addition, we invested $30.5 million in ABG units. The investment is considered a cost method investment and is included in investment in Unconsolidated Real Estate Affiliates on the Consolidated Balance Sheets. On August 9, 2019, the Company completed the sale of 49.3% of its interest in ABG for a gross sales price of $32.1 million (see above for further discussion). On December 15, 2017, we closed on the sale of The Shops at Fallen Timbers in Maumee, Ohio for $21.0 million . The transaction resulted in a loss on sale of $0.3 million recognized in gains from changes in control of investment properties and other for the year ended December 31, 2017. On October 3, 2017, we acquired a 100% interest in two anchor boxes at Neshaminy Mall and Oakwood Center located in Bensalem, Pennsylvania and Gretna, Louisiana, respectively. The gross consideration of the two acquired anchor boxes was $21.4 million . On September 19, 2017, we entered into three transactions with affiliates of Thor Equities ("Thor") related to three separate joint ventures with Thor. First, we acquired 49.9% of its partner's interest in 218 West 57th Street based on a gross property valuation of $104.0 million . After the acquisition, we owned a 99.9% interest in 218 West 57th Street, while Thor retained a 0.1% interest. A portion of the net proceeds from the acquisition were used by Thor to pay off their $12.3 million note receivable to the Company related to the property. Of the remaining net proceeds, $9.75 million was used to pay down a portion of their note receivable for 530 Fifth Avenue and $3.36 million was used to pay down a portion of their note receivable to the Company for 685 Fifth Avenue. Second, we recapitalized the 530 Fifth Avenue joint venture based on a gross property valuation of $334 million , whereby (i) Thor’s common interest having a value of $48.1 million was converted to a preferred equity interest with a 7.0% cumulative return in 530 Fifth Avenue, which serves as collateral for Thor's still-outstanding note receivable, and (ii) we owned a 90.23% common equity interest in 530 Fifth Avenue, while Thor retained a 9.77% common equity interest. The preferred return payable to Thor must first go toward interest and principal due to the Company under Thor’s note receivable for 530 Fifth Avenue. Finally, we agreed to recapitalize the 685 Fifth Avenue joint venture based on a gross property valuation of $652.6 million , whereby upon closing (i) Thor’s common interest having a value of $150 million was converted to a preferred equity interest with a 7.0% cumulative return in 685 Fifth Avenue, which serves as collateral for Thor's still-outstanding note receivable, and (ii) we own a 97.03% common equity interest in 685 Fifth Avenue, while Thor retains a 2.97% common equity interest. The preferred return payable to Thor must first go toward interest and principal due to the Company under Thor’s note receivable for 685 Fifth Avenue. The recapitalization was effective on December 31, 2017. We had previously accounted for our interest in these three joint ventures using the equity method of accounting ( Note 2 ). As a result of the transactions described above, we now consolidate these joint ventures with our joint venture partners' share of equity included in noncontrolling interest ( Note 2 ). In addition, the $48.1 million and $151.3 million notes receivable due from our joint venture partner at 530 Fifth Avenue and 685 Fifth Avenue, respectively, are presented on the consolidated balance sheets in noncontrolling interests in consolidated real estate affiliates. The notes receivable and our joint venture partners' share of equity effectively net within the noncontrolling interest.

Both loans eliminate in consolidation. (2) 530 Fifth Avenue includes a $9.4 million escrow. Capitalization rates and discount rates were based on a reasonable range of current market rates for 218 West 57th Street, 530 Fifth Avenue and 685 Fifth Avenue. Based upon these inputs, we determined that our valuations of the properties using a discounted cash flow or a direct capitalization model were classified within Level 3 of the fair value hierarchy ( Note 2 ). Unobservable Quantitative Input Range Discount Rates 6.0% to 7.0% Terminal capitalization rates 4.0% to 5.5% On July 12, 2017, we closed on the acquisition of the remaining 50% interest in eight of the 12 anchor boxes included in the existing GS Portfolio Holdings LLC ("GSPH") joint venture with Seritage Growth Properties ("Seritage") for $190.1 million based on a total valuation of $380.2 million . We had previously owned a 50% interest in the joint venture and accounted for the joint venture using the equity method of accounting ( Note 2 ), but as a result of the transaction we now consolidate our 100% interest in the eight acquired anchor boxes. Of the total purchase price, $126.4 million was settled upon closing and Seritage retained certain special rights (governed by a Special Rights Agreement), which were callable by the Company for $63.7 million and were paid in full as of December 31, 2018. Simultaneously, the four remaining anchor boxes in GSPH were distributed to a newly formed joint venture, GS Portfolio Holdings II, LLC ("GSPHII"), between the Company and Seritage in which the ownership interest remains at 50% for both joint venture partners. We account for GSPHII using the equity method of accounting ( Note 2 ). In addition, BPROP provided a loan to GSPHII for $127.4 million . This loan is collateralized by GSPHII's interest in the properties ( Note 14 ). Finally, we acquired a 50% interest in five anchor boxes through a newly formed joint venture, GS Portfolio Holdings 2017 ("GSPH2017"), for $57.5 million . We account for this joint venture using the equity method of accounting ( Note 2 ). The table below summarizes the gain from changes in control calculation ($ in millions): Gain from a Change of Control in GSPH Consideration paid to acquire our joint venture partner's interest $ 190.1 Less: carrying value of Investment in Unconsolidated Real Estate Affiliates 147.2 Gain from changes in control of investment properties and other, net $ 42.9 On June 30, 2017, we conveyed Lakeside Mall to the lender in full satisfaction of $144.5 million in outstanding debt. This transaction resulted in a $55.1 million gain on extinguishment of debt for the year ended December 31, 2017. On June 9, 2017, we closed on the acquisition of our joint venture partner's 50% interest in Neshaminy Mall located in Bensalem, Pennsylvania for a gross purchase price of $65.0 million . Post-acquisition, we own 100% of the mall. Prior to the acquisition of the remaining interest, the carrying value for our investment was $55.2 million . As a result of this acquisition, the implied fair value of our previous investment in Neshaminy Mall is $34.2 million , resulting in a loss of $21.0 million , recognized in loss from changes in control of investment properties and other for the year ended December 31, 2017. On May 12, 2017, we closed on the sale of Red Cliffs Mall in St. George, Utah for $39.1 million . The transaction netted proceeds of approximately $36.3 million and resulted in a gain on sale of $5.6 million recognized in gain from changes in control of investment properties and other for the year ended December 31, 2017.

Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE Nonrecurring Fair Value Measurements We estimate fair value relating to impairment assessments based upon discounted cash flow and direct capitalization models that include all projected cash inflows and outflows over a specific holding period, or the negotiated sales price, if applicable. Such projected cash flows are comprised of contractual rental revenues and forecasted rental revenues and expenses based upon market conditions and expectations for growth. Capitalization rates and discount rates utilized in these models are based on a reasonable range of current market rates for each property analyzed. Based upon these inputs, we determined that our valuations of properties using a discounted cash flow or a direct capitalization model were classified within Level 3 of the fair value hierarchy. For our properties for which the estimated fair value was based on negotiated sales prices, we determined that our valuation was classified within Level 2 of the fair value hierarchy. The following table summarizes certain of our assets that are measured at fair value on a nonrecurring basis as a result of impairment charges recorded during the years ended December 31, 2019 and 2018 . No impairment charges were recognized during the year ended December 31, 2017.

(2) Includes net $7.7 million of market rate adjustments and $123.8 million of deferred financing costs. The fair value of our junior subordinated notes approximates their carrying amount as of December 31, 2019 and 2018 . We estimated the fair value of mortgages, notes and other loans payable using Level 2 and Level 3 inputs based on recent financing transactions, estimates of the fair value of the property that serves as collateral for such debt, historical risk premiums for loans of comparable quality, current LIBOR , U.S. treasury obligation interest rates and on the discounted estimated future cash payments to be made on such debt. The discount rates estimated reflect our judgment as to what the approximate current lending rates for loans or groups of loans with similar maturities and assume that the debt is outstanding through maturity. We have utilized market information as available or present value techniques to estimate the amounts required to be disclosed. Since such amounts are estimates that are based on limited available market information for similar transactions and do not acknowledge transfer or other repayment restrictions that may exist in specific loans, it is unlikely that the estimated fair value of any such debt could be realized by immediate settlement of the obligation.

(2) Includes management fees charged to the unconsolidated joint ventures by BPRRS and BPRI. The Unconsolidated Real Estate Affiliates represent our investments in real estate joint ventures that are not consolidated. We hold interests in 26 domestic joint ventures, comprising 60 U.S. retail properties and one joint venture in Brazil. Generally, we share in the profits and losses, cash flows and other matters relating to our investments in Unconsolidated Real Estate Affiliates in accordance with our respective ownership percentages. We manage most of the properties owned by these joint ventures. We account for investments in joint ventures where we own a non-controlling joint interest using either the equity method or the cost method. If we have significant influence but not control over the investment, we utilize the equity method. If we have neither control nor significant influence, we utilize the cost method. If we control the joint venture, we account for the venture as a consolidated investment. As of December 31, 2019 , the balance of ROU assets was $68.9 million , net and lease liabilities was $71.0 million for 24 ground leases in the Condensed Combined Balance Sheets - Unconsolidated Real Estate Affiliates under ASC 842, included in prepaid expenses and other assets and accounts payable and accrued expenses, respectively. All of these leases are operating leases; we do not have any finance leases. On December 23, 2019, an equity method investment of the Company formed a joint venture with a third party to develop and operate a residential building adjacent to a retail property owned by the equity method investment. The Company's effective ownership of this new venture is 12.5% , and management has concluded that the Company has the ability to exercise significant influence over the entity. Therefore, the Company is accounting for its investment in the new venture using the equity method of accounting. On September 30, 2019, the Company completed the sale of certain space formerly occupied by Barneys at Grand Canal Shoppes for a gross sales price of $37.6 million , which resulted in $15.9 million included in Equity in Income of Unconsolidated Real Estate Affiliates on the Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2019 . On September 19, 2017, we entered into three transactions with affiliates of Thor related to joint ventures between the Company and Thor at 218 West 57th Street, 530 Fifth Avenue and 685 Fifth Avenue. As a result of these transactions, we changed our method of accounting for these three joint ventures from the equity method of accounting. We now consolidate the joint ventures with our joint venture partner's share of equity included in noncontrolling interest ( Note 3 ). On July 12, 2017, we closed on the acquisition of the remaining 50% interest in eight anchor boxes included in the GSPH joint venture with Seritage. We had previously owned a 50% interest in the joint venture and accounted for the joint venture using the equity method of accounting, but as a result of the transaction we now consolidate our 100% interest in the eight acquired anchor boxes. Simultaneously, we distributed the four remaining anchor boxes in GSPH to a newly formed joint venture, GSPHII, between the Company and Seritage in which the ownership interest remains at 50% for both joint venture partners, and we continue to account for this joint venture using the equity method of accounting. Seritage has the right to cause the Company to purchase from GSPHII any property with respect to which a certain leasing threshold has been satisfied at the fair market value of the property, less certain mortgage loans and other debt in respect of such property and certain selling expenses, determined in accordance with the limited liability company agreement of GSPHII. As of December 31, 2019 , this right is not yet exercisable. Finally, we acquired a 50% interest in five anchor boxes through a newly formed joint venture, GSPH2017, which we account for using the equity method of accounting. On June 1, 2017, we received an additional 7.3% of our joint venture partner's membership interests in Miami Design District in full satisfaction of two promissory notes for $57.6 million and $40.4 million , respectively, resulting in a total ownership of 22.3% . We determined that we had significant influence over the investment subsequent to the acquisition of the additional interest, and therefore we changed our method of accounting for this joint venture from the cost method to the equity method ( Note 2 ). Condominium Sales and Condominium Cost of Sales On March 7, 2014, we formed a joint venture, AMX Partners, LLC, with Kahikolu Partners, LLC, for the purpose of constructing a luxury residential condominium tower (the Park Lane condominium project) on a site located within the Ala Moana Shopping Center. Under the previous revenue recognition guidance, the percentage of completion method was used to account for the sales revenue of the Park Lane condominium project. Upon adoption of the new revenue recognition standard ( Note 2 ), risks and rewards of ownership and control over the condominium unit transfers upon the closing of the sale to the customer, and as such, the joint venture will recognize revenue for the condominium unit upon closing. Unconsolidated Mortgages, Notes and Loans Payable and Retained Debt Our proportionate share of the mortgages, notes and loans payable of the unconsolidated joint ventures was $7.2 billion as of December 31, 2019 and $7.6 billion as of December 31, 2018 , including Retained Debt (as defined below). There can be no assurance that the Unconsolidated Properties will be able to refinance or restructure such debt on acceptable terms or otherwise, or that joint venture operations or contributions by us and/or our partners will be sufficient to repay such loans. On November 1, 2019, the Company closed a new loan on Natick Mall for $505.0 million with a 5-year fixed interest rate at 3.72% which matures on November 1, 2024. This loan replaced the previous debt of $419.4 million with an interest rate of 4.60% that matured on November 1, 2019. On, October 25, 2019, the Company closed a new loan on First Colony Mall for $220.0 million with a 10-year fixed interest rate at 3.55% which matures on November 1, 2029. This loan replaced the previous debt of $168.6 million with an interest rate of 4.50% that matured on November 1, 2019. On August 9, 2019, the Company closed on new debt at the SoNo Collection for $305.0 million . This debt is comprised of a $245.0 million mortgage loan and a $60.0 million mezzanine loan with respective interest rates of LIBOR plus 3.02% and LIBOR plus 6.75% . The loans mature on August 6, 2023. On June 3, 2019, the Company closed on new debt on the Grand Canal Shoppes in the amount of $975.0 million with a 10-year fixed interest rate of 4.29% , which matures on July 2, 2029. This loan replaced the previous debt of $625.0 million on the property that matured on June 3, 2019. On April 9, 2019, the Company closed on new debt on three properties included in the BPR-FF JV LLC joint venture ( Note 3 ). The three properties are Coronado Center, Governor's Square and Lynnhaven Mall. These properties were previously encumbered by $462.0 million of third-party debt which was replaced by a $515.0 million loan with an interest rate of LIBOR plus 340 basis points, maturing May 1, 2024. The new loan was recorded as an extinguishment of the previous loans and allocation of the new debt to the three properties. We have debt obligations in excess of our pro rata share of the debt for one of our Unconsolidated Real Estate Affiliates ("Retained Debt"). This Retained Debt represents distributed debt proceeds of the Unconsolidated Real Estate Affiliates in excess of our pro rata share of the non-recourse mortgage indebtedness. The proceeds of the Retained Debt which were distributed to us are included as a reduction in our investment in Unconsolidated Real Estate Affiliates. We had Retained Debt of $81.5 million at one property as of December 31, 2019 , and $83.3 million as of December 31, 2018 . We are obligated to contribute funds on an ongoing basis, as needed, to our Unconsolidated Real Estate Affiliates in amounts sufficient to pay debt service on such Retained Debt. If we do not contribute such funds, our interest in or our distributions from such Unconsolidated Real Estate Affiliates could be reduced to the extent of such deficiencies. As of December 31, 2019 , we do not anticipate an inability to perform on our obligations with respect to Retained Debt.

Collateralized Mortgages, Notes and Loans Payable As of December 31, 2019 , $16.0 billion of land, buildings and equipment (before accumulated depreciation) and construction in progress have been pledged as collateral for our consolidated mortgages, notes and loans payable. Certain of these consolidated secured loans, representing $1.3 billion of debt, are cross-collateralized. Although a majority of the $10.2 billion of consolidated fixed and variable rate collateralized mortgages, notes and loans payable are non-recourse, $739.7 million of such mortgages, notes and loans payable are recourse to the Company as guarantees on secured financings. In addition, certain mortgage loans contain other credit enhancement provisions which have been provided by BPR. Certain mortgages, notes and loans payable may be prepaid but are generally subject to a prepayment penalty equal to a yield-maintenance premium, defeasance or a percentage of the loan balance.

The notes bear interest at an annual rate of 5.75% payable on May 15 and November 15 of each year, beginning on November 15, 2019 and will mature on May 15, 2026. During the last quarter of 2019, the Company made a principal payment in amount of $50 thousand . On March 25, 2019, the Company secured a $341.8 million subordinated unsecured note with Brookfield BPY Holdings Inc., a related party. The note bears interest at a rate equal to LIBOR plus 2.75% and is scheduled to mature on March 25, 2029. During the year ended December 31, 2019 , the Company repaid this loan in full. The Company borrowed an additional $70.5 million during the second quarter of 2019, with a maturity date of June 25, 2029.

The Company entered into a new credit agreement (the "Agreement") dated as of August 24, 2018 consisting of a revolving credit facility (the "Facility"), Term A-1 and A-2 loans, and a Term B loan. The Facility provides for revolving loans of up to $1.5 billion and borrowings bear interest at a rate equal to LIBOR plus 225 basis points. The Facility is scheduled to mature in August 2022 and had outstanding borrowings of $715.0 million as of December 31, 2019 . The Term A-1 Loan has a total commitment outstanding of $900.0 million , with $700.0 million attributable to BPR and $200.0 million attributable to an affiliate, and is scheduled to mature in August 2021, bearing interest at a rate equal to LIBOR plus 225 basis points. During the year ended December 31, 2019 , the Company made principal payments totaling $491.5 million with a remaining outstanding balance as of December 31, 2019 was $34.8 million .

During the year ended December 31, 2019 , the Company made principal payments totaling $20.0 million with a remaining outstanding balance of $1,975.0 million at December 31, 2019 . The Term A-1, A-2, and B Loans are contractually obligated to be prepaid through net proceeds from property level refinances and asset sales as outlined in the Agreement. The Agreement contains certain restrictive covenants which limit material changes in the nature of our business conducted, including, but not limited to, mergers, dissolutions or liquidations, dispositions of assets, liens, incurrence of additional indebtedness, dividends, transactions with affiliates, prepayment of subordinated debt, negative pledges and changes in fiscal periods. In addition, we are required to maintain compliance with certain financial covenants related to a maximum net debt-to-value ratio and a minimum fixed-charge-coverage ratio, as defined in the Agreement. As of December 31, 2019 , we are not aware of any instances of non-compliance with such covenants. Though there is potential for a risk of default, in the event the Company fails to maintain compliance with its financial covenants, the Agreement provides for a cure period, during which the Company has the opportunity to raise additional cash and reduce net debt balance, such as through capital contributions from BPY or disposition of assets. Management has determined that in the event of a default, it is probable that these market-based alternatives would be available, and that these actions would provide the necessary cash flows to prevent or cure an event of default. Junior Subordinated Notes GGP Capital Trust I, a Delaware statutory trust (the "Trust") completed a private placement of $200.0 million of trust preferred securities ("TRUPS") in 2006. The Trust also issued $6.2 million of common securities to BPROP. The Trust used the proceeds from the sale of the TRUPS and common securities to purchase $206.2 million of floating rate junior subordinated notes of BPROP due 2036. Distributions on the TRUPS are equal to LIBOR plus 1.45% . Distributions are cumulative and accrue from the date of original issuance. The TRUPS mature on April 30, 2036, but may be redeemed beginning on April 30, 2011 if the Trust exercises its right to redeem a like amount of junior subordinated notes. The junior subordinated notes bear interest at LIBOR plus 1.45% and are fully recourse to the Company. We have recorded the junior subordinated notes as a liability and our common equity interest in the Trust as prepaid expenses and other assets in our Consolidated Balance Sheets as of December 31, 2019 and December 31, 2018 . Letters of Credit and Surety Bonds We had outstanding letters of credit and surety bonds of $50.0 million and $42.4 million as of December 31, 2019 and 2018 , respectively. These letters of credit and bonds were issued primarily in connection with insurance requirements, special real estate assessments and construction obligations. We are not aware of any instances of non-compliance with our financial covenants related to our mortgages, notes and loans payable as of December 31, 2019 .

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended. We intend to maintain REIT status. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement to distribute at least 90% of our taxable ordinary income. In addition, the Company is required to meet certain asset and income tests. As a REIT, we will generally not be subject to corporate level Federal income tax on taxable income we distribute currently to our stockholders. If we fail to qualify as a REIT in any taxable year, we will be subject to Federal income taxes at regular corporate rates and may not be able to qualify as a REIT for four subsequent taxable years. Even if we qualify for taxation as a REIT, we may be subject to certain state and local taxes on our income or property, and to Federal income and excise taxes on our undistributed taxable income and capital gains. We are currently statutorily open to audit by the Internal Revenue Service for the years ended December 31, 2016 through 2019 and are statutorily open to audit by state taxing authorities for the years ended December 31, 2015 through 2019 . In conjunction with the BPY Transaction, certain of BPR’s subsidiaries contributed in a taxable manner a portion of their interests in specific assets to a newly formed corporate subsidiary of BPRI. This taxable contribution caused an increase in the tax basis of the contributed assets to fair market value and generated a related taxable gain to the Company, which has been distributed to shareholders. The increase in tax basis in the assets created a book to tax basis temporary difference of approximately $2.6 billion and a related deferred tax asset of $638.5 million within the newly formed subsidiary of BPRI. We determined that this deferred tax asset was properly recorded through our consolidated income statements and that no valuation allowance is necessary on the deferred tax assets as of December 31, 2019 primarily due to our ability to recognize the benefit of the increased tax basis through operations or sale of properties. The provision for (benefit from) income taxes for the years ended December 31, 2019 , 2018 , and 2017 are as follows: December 31, 2019 December 31, 2018 December 31, 2017 Current $ 17,568 $ 6,499 $ 8,658 Deferred (7,885 ) (600,685 ) (19,554 ) Total $ 9,683 $ (594,186 ) $ (10,896 ) Total provision for (benefit from) income taxes computed for continuing operations by applying the Federal corporate tax rate for the years ended December 31, 2019, 2018 and 2017 were as follows: December 31, 2019 December 31, 2018 December 31, 2017 Tax at statutory rate on earnings from continuing operations before income taxes $ 93,239 $ 734,235 $ 226,254 Increase in valuation allowance, net 1,505 117 — State income taxes, net of federal income tax 5,649 2,879 1,773 Investment Tax Credits (1,958 ) (12,134 ) (18,467 ) Tax at statutory rate on REIT losses not subject to Federal income taxes (87,988 ) (695,546 ) (209,165 ) Tax expense from prior period 13,514 16,369 244 Tax benefit from change in rates (15,538 ) — (14,482 ) Tax benefit from BPY Transaction — (638,494 ) — Other permanent differences 1,260 (1,612 ) 2,947 Provision for (benefit from) income taxes $ 9,683 $ (594,186 ) $ (10,896 ) Realization of a deferred tax benefit is dependent upon generating sufficient taxable income in future periods. The Company has $31.1 million of federal and state loss carryforwards, the majority of which are currently scheduled to expire in subsequent years through 2039. State operating losses of $6.7 million generated during 2018 and later will be carried forward indefinitely until utilized. Each TRS and certain REIT entities subject to state income taxes are tax paying components for purposes of classifying deferred tax assets and liabilities. Net deferred tax assets (liabilities) are summarized as follows: December 31, 2019 December 31, 2018 December 31, 2017 Total deferred tax assets $ 638,513 $ 630,215 $ 29,801 Valuation allowance (10,362 ) (8,857 ) (8,740 ) Net deferred tax assets 628,151 621,358 21,061 Total deferred tax liabilities (2,491 ) (2,083 ) (2,428 ) Net deferred tax assets $ 625,660 $ 619,275 $ 18,633 Due to the uncertainty of the realization of certain tax carryforwards, we have established valuation allowances on those deferred tax assets that we do not reasonably expect to realize. Deferred tax assets that we believe have only a remote possibility of realization have not been recorded. The tax effects of temporary differences and carryforwards included in the net deferred tax assets (liabilities) as of December 31, 2019 , December 31, 2018 and December 31, 2017 are summarized as follows: December 31, 2019 December 31, 2018 (1) December 31, 2017 Operating loss and other carryforwards (2) $ 42,187 $ 58,328 $ 47,577 Other TRS property, primarily differences in basis of assets and liabilities 582,970 564,528 (20,204 ) Interest deduction carryforwards 10,865 5,276 — Valuation allowance (10,362 ) (8,857 ) (8,740 ) Net deferred tax assets $ 625,660 $ 619,275 $ 18,633 _______________________________________________________________________________ (1) Due to the changes in the Tax Cuts and Jobs Act, the deferred tax assets and liabilities including the valuation allowances were revalued as of December 31, 2017 using the new corporate tax rate.

Leases [Abstract]
LEASES	LEASES Lessee arrangements We are the lessee in several ground lease agreements for the land under some of our owned buildings. Generally, we own the land underlying the properties; however, at certain properties, all or part of the underlying land is owned by a third party that leases the land to us through a long-term ground lease. In addition, we lease office space for our corporate headquarters and field offices. Our material consolidated leases have reasonably certain lease terms ranging from 4 years to 40 years . Certain leases provide the lessee with two to three renewal options which are considered to be termination options unless it is reasonably certain that the Company will elect to renew and generally range from five years to ten years each, with renewal rent payments based on a predetermined annual increase, market rates at the time of exercise of the renewal, or changes in the Consumer Price Index ("CPI"). As of December 31, 2019 , the balance of operating ROU assets was $402.6 million , net and lease liabilities of $78.5 million for eight ground leases and one office lease in the Consolidated Balance Sheets under Topic 842, included in prepaid expenses and other assets and accounts payable and accrued expenses, respectively. The maturity of our operating lease liabilities as of December 31, 2019 is as follows: Year Amount 2020 $ 9,305 2021 9,520 2022 9,754 2023 10,018 2024 10,250 2025 and thereafter 165,583 Total undiscounted lease payments 214,430 Less: Present value adjustment (135,930 ) Total lease liability $ 78,500 The maturity of our operating lease liabilities as of December 31, 2018 is as follows: Year Amount 2019 $ 9,948 2020 10,164 2021 10,386 2022 10,592 2023 10,794 2024 and thereafter 118,835 Total $ 170,719 Straight-line rent expense recognized for our consolidated operating leases was $2.8 million and $3.7 million for ground leases and $7.9 million and $8.0 million for the office lease for the years ended December 31, 2019 and 2018 , respectively, and are included in other property operating costs for ground leases and property management and other costs for the office lease, in the Consolidated Statements of Operations and Comprehensive Income. Several lease agreements include variable lease payments which vary based on factors such as sublease income received, the revenues or net operating income of the properties constructed on the leased premises, increases in CPI, and changes in market rents. In addition, our leases require us to reimburse the lessor for the lessor’s tax, insurance and common area costs. Variable lease payments and short-term lease costs recognized as rent expense for operating leases were not significant for the years ended December 31, 2019 and 2018 and are included in other property operating costs in the Consolidated Statements of Operations and Comprehensive Income. The following summarizes additional information related to our operating leases as of December 31, 2019 : Weighted-average remaining lease term (years) 23.0 Weighted-average discount rate 7.67% Supplemental disclosure for the consolidated statement of cash flows: Cash paid for amounts included in the measurement of lease liabilities $8,636 Lessor arrangements We own a property portfolio comprised primarily of Class A retail properties and lease these retail spaces to tenants. As of December 31, 2019 , we own a controlling interest in and consolidated 62 retail properties located throughout the United States comprising approximately 55 million square feet of GLA. We enter into operating leases with a variety of tenants, the majority of which are national and regional retail chains and local retailers. These operating leases expire starting in year 2020 and typically include renewal options, which are generally exercisable only by the tenant. Certain leases also include early termination options which are typically exercisable only by the tenant. Our leases do not allow the tenant to purchase the retail space. Minimum future rentals exclude amounts which are payable by certain tenants based upon a percentage of their gross sales or as reimbursement of operating expenses and amortization of above and below-market tenant leases. Consequently, our credit risk is concentrated in the retail industry. The maturity analysis of the lease payments we expect to receive from our operating leases as of December 31, 2019 are as follows: Year Amount 2020 $ 1,105,295 2021 1,035,494 2022 930,124 2023 815,823 2024 691,981 Subsequent 2,369,894 $ 6,948,611 The maturity analysis of the lease payments we expect to receive from our operating leases as of December 31, 2018 are as follows: Year Amount 2019 $ 764,196 2020 696,381 2021 621,582 2022 543,232 2023 464,453 Subsequent 1,442,312 $ 4,532,156 All lease-related income is reported as a single line item, rental revenues, in our Consolidated Statements of Operations and Comprehensive Income. Effective January 1, 2019, with the adoption of ASC 842, rental revenues is presented net of provision for doubtful accounts. Rental income recognized on a straight-line basis consists primarily of fixed and in-substance fixed lease payments (including lease payments related to non-lease components which have been combined with the lease component). Variable rental income represents variable lease payments, which consist primarily of overage rents; reimbursements for tenants’ pro rata share of real estate taxes, insurance, property operating and marketing expenses, and utilities; lease payments related to CPI-based escalations and market rent resets; and lease termination income. In accordance with the terms of our operating leases, we bill our tenants separately for minimum rents, tenant recoveries and overage rents, lease termination income as shown below for the year ended December 31, 2019 : Year Ended December 31, 2019 Minimum rents, billed $ 916,624 Tenant recoveries, billed 362,840 Lease termination income, billed 13,235 Overage rent, billed 25,193 Total contractual operating lease billings 1,317,892 Adjustment to recognize contractual operating lease billings on a straight-line basis 8,488 Above and below-market tenant leases, net 22,037 Less provision for doubtful accounts (10,733 ) Total rental revenues, net $ 1,337,684 Of the total contractual rental revenues we have billed, 77.6% are fixed lease payments for the year ended December 31, 2019 .

EQUITY AND REDEEMABLE NONCONTROLLING INTERESTS	EQUITY AND REDEEMABLE NONCONTROLLING INTERESTS Allocation to Noncontrolling Interests Noncontrolling interests consists of the redeemable interests related to BPROP Common, Preferred, and LTIP Units and the noncontrolling interest in our consolidated joint ventures. The following table reflects the activity included in the allocation to noncontrolling interests. Year Ended December 31, 2019 2018 2017 Distributions to preferred BPROP units ("Preferred Units") $ (5,752 ) $ (4,636 ) $ (1,867 ) Net income allocation to noncontrolling interests in BPROP from continuing operations ("Common Units") — (31,803 ) (4,830 ) Net income allocation to noncontrolling interests in BPROP from continuing operations ("LTIP units") — (8,159 ) (1,502 ) Net income allocated to noncontrolling interest in consolidated real estate affiliates (577 ) (915 ) (1,340 ) Net income allocated to noncontrolling interests of the Operating Partnership (1) (41,702 ) (27,715 ) — Allocation to noncontrolling interests (48,031 ) (73,228 ) (9,539 ) Other comprehensive (income) loss allocated to noncontrolling interests — (39 ) 89 Comprehensive income allocated to noncontrolling interests $ (48,031 ) $ (73,267 ) $ (9,450 ) _______________________________________________________________________________ (1) Represents the noncontrolling interest of our institutional investor ( Note 3 ). Noncontrolling Interests The noncontrolling interest related to the Common, Preferred, and LTIP Units of BPROP are presented either as redeemable noncontrolling interests in mezzanine equity or as noncontrolling interests in our permanent equity on our Consolidated Balance Sheets. Classification as redeemable or permanent equity is considered on a tranche-by-tranche basis and is dependent on whether we could be required, under certain events outside of our control, to redeem the securities for cash by the holders of the securities, those tranches for which we could be required to redeem the security for cash are included in redeemable equity. If we control the decision to redeem the securities for cash, the securities are classified as permanent equity. The redeemable Common and Preferred Units of BPROP are recorded at the greater of the carrying amount adjusted for the noncontrolling interest’s share of the allocation of income or loss (and its share of other comprehensive income or loss) and dividends or their redemption value (i.e. fair value) as of each measurement date. The excess of the fair value over the carrying amount from period to period is recorded within additional paid-in capital in our Consolidated Balance Sheets. Allocation to noncontrolling interests is presented as an adjustment to net income to arrive at net income (loss) attributable to BPR. The preferred redeemable noncontrolling interests have been recorded at carrying value. Holders of Series B Preferred Units, Series D Preferred Units, Series E Preferred Units and Series G Preferred Units of BPROP are each entitled to periodic distributions at the rates set forth in the Sixth Amended and Restated Agreement of Limited Partnership of BPROP. Generally, each Series K Preferred Unit of BPROP entitles its holder to distributions and a liquidation preference identical to those established for each share of BPR's Class A Stock. The holders of Series L Preferred Units of BPROP are generally entitled to a pro rata distribution of an aggregate cash amount equal to the sum of (i) the aggregate cash dividends declared on all outstanding shares of BPR's Class B-1 Stock and Class B-2 Stock (together, the "Class B Stock") and (ii) the aggregate cash dividends declared on all outstanding shares of BPR's Series B Preferred Stock. Holders of Common Units of BPROP are entitled to distributions of all or a portion of BPROP’s remaining net operating cash flow, when and as declared by BPROP’s general partner. However, the Sixth Amended and Restated Agreement of Limited Partnership of BPROP permits distributions solely to BPR if such distributions were required to allow the Company to comply with the REIT distribution requirements or to avoid the imposition of excise tax. Noncontrolling Interests - Permanent As of December 31, 2019 , there were 9,717.658 Series B Preferred Units of BPROP outstanding. The Series B Preferred Units have a carrying value of $50 per unit. Also, as of December 31, 2019 , there were 4,156,971.851 Common Units of BPROP outstanding and 1,691,144.853 Series K Preferred Units of BPROP held by former common unit holders. These Series K Units were established at $21 per unit and are not subject to adjustment based on fair value. Noncontrolling Interests - Redeemable The Series D Preferred Units of BPROP are convertible based on a conversion ratio of 1.50821 , which is the quotient of the Series D Preferred Unit’s $50 liquidation preference and $33.151875 conversion price. Upon conversion, each Series D Preferred Unit entitles its holder to (i) $21.9097 in cash, (ii) a number of Series K Preferred Units of BPROP equal to (x) 0.40682134 Series K Preferred Units (which is subject to adjustment), multiplied by (y) the Series D conversion ratio; and (iii) a number of Common Units of BPROP equal to (x) one Common Unit (which is subject to adjustment), multiplied by (y) the Series D conversion ratio. As of December 31, 2019 , there were 532,749.6574 Series D Preferred Units of BPROP outstanding.

If the holders had requested redemption of the Class A Stock and Preferred Units as of December 31, 2019 , the aggregate amount of cash the Company would have paid would have been $1.18 billion and $57.9 million , respectively. The following table reflects the activity of the redeemable noncontrolling interests for the years ended December 31, 2019 , 2018 , and 2017 .

Each share of Class A Stock is entitled to cumulative dividends per share in a cash amount equal in value to the amount of any distribution made on a BPY limited partnership unit ("BPY unit"). In addition, each share of Class A Stock is exchangeable for one BPY unit or its cash equivalent (the form of payment to be determined by BPY or an affiliate, in its sole discretion). Such exchange and distribution rights are subject to adjustment in the event of certain dilutive or other capital events by BPY or BPR. If and to the extent declared by the Company's board of directors, the record and payment dates for the dividends or other distributions upon the shares of Class A Stock, to the extent not prohibited by applicable law, is expected to be the same as the record and payment dates for the dividends or other distributions upon the BPY units. Pursuant to the terms of the Company's charter, all such dividends to holders of Class A Stock will be paid prior and in preference to any dividends or distributions on the Class B Stock, Series B Preferred Stock or Class C Stock will be fully declared and paid before any dividends are declared and paid or any other distributions are made on any Class B Stock, Series B Preferred Stock or Class C Stock. The holders of Class A Stock shall not be entitled to any dividends from BPR other than the Class A dividend. Upon any liquidation, dissolution or winding up of the Company that is not a Market Capitalization Liquidation Event (as defined below) or substantially concurrent with the liquidation, dissolution or winding up of BPY, the holders of Class A Stock are entitled to a cash amount, for each share of Class A Stock, equal to the market price of one BPY unit (subject to adjustment in the event of certain dilutive or other capital events by BPY or BPR) on the date immediately preceding announcement of such liquidation, dissolution or winding up, plus all declared and unpaid dividends. If, upon any such liquidation, dissolution or winding up, the assets of BPR are insufficient to make such payment in full, then the assets of BPR will be distributed among the holders of Class A Stock ratably in proportion to the full amounts to which they would otherwise be respectively entitled to receive. If the market capitalization of the Class A Stock (i.e., if the price per share of Class A Stock, multiplied by the number of shares of Class A Stock outstanding) averages, over any period of 30 consecutive trading days, less than one (1) billion dollars, the BPR board will have the right to liquidate BPR’s assets and wind up BPR’s operations (a "Market Capitalization Liquidation Event"). Upon any Market Capitalization Liquidation Event, the holders of Class A Stock shall be entitled to a cash amount, for each share of Class A Stock, equal to the dollar volume-weighted average price of one BPY unit over the ten (10) trading days immediately following the public announcement of such Market Capitalization Liquidation Event, plus all declared and unpaid dividends. If, upon any such Market Capitalization Liquidation Event, the assets of BPR are insufficient to make such payment in full, then the assets of BPR will be distributed among the holders of Class A Stock ratably in proportion to the full amounts which they would otherwise be respectively entitled to receive. Notwithstanding the foregoing, upon any Market Capitalization Liquidation Event, BPY may elect to exchange all of the outstanding shares of the Class A Stock for BPY units on a one-for-one basis, subject to adjustment in the event of certain dilutive or other capital events by BPY or BPR. Holders of Class A Stock shall have the right to exchange all or a portion of their Class A Stock for cash at a price equal to the value of an equivalent number of BPY units, subject to adjustment in the event of certain dilutive or other capital events by BPY or BPR. Upon receipt of a request for exchange, BPR will deliver a notice of exchange to BPY within one (1) business day and will have ten (10) business days to deliver the cash amount to the tendering holder. Upon receipt of the notice of exchange, BPY or an affiliate may elect to satisfy BPR’s exchange obligation by exchanging all of the shares of the Class A Stock tendered for BPY units on a one-for-one basis. This initial one-for-one conversion factor is subject to adjustment in the event of certain dilutive or other capital events by BPY or BPR. If so elected, BPY will have to satisfy such obligation within ten (10) business days from the date of the notice of exchange. If BPY exercises its right to assume the exchange obligation, BPY units will be delivered in exchange for the Class A Stock and such Class A Stock will automatically be converted into Class B Stock. As there are certain events outside of the Company’s control whereby it could be required to redeem the Class A Stock for cash by the holders of the securities, the Class A Stock is included in redeemable equity. Accordingly, the Class A Stock are recorded at the greater of the carrying amount or their redemption value (i.e. fair value) as of each measurement date. The excess of the fair value over the carrying amount from period to period is recorded within additional paid-in capital in the Company’s Consolidated Balance Sheets. There is no adjustment within additional paid-in capital for the Class A stock when the fair value is less than the carrying value. Class B Stock The Company’s shareholders approved the amendment and restatement of the Company’s charter at its annual stockholder meeting on June 19, 2019 (the “Restated Charter”), which became effective on June 26, 2019 and, among other things, authorized the Company’s issuance of up to 965,000,000 shares of a new class of stock called Class B-2 Stock, par value of $0.01 per share. Each share of Class B-2 Stock shall have terms (including the same powers, preferences and relative, participating, optional and other special rights, and qualifications, limitations and restrictions) identical to the terms of a share of Class B-1 Stock other than voting rights. The following description sets forth certain general terms and provisions of the Class B Stock. Pursuant to the Restated Charter and subject to the prior rights of holders of all classes, including the Class A Stock, and any series of preferred stock at the time outstanding having prior rights as to dividends, each share of Class B Stock entitles its holder to cumulative dividends per share in a cash amount at a rate of 6.5% per year of the Class B liquidation amount per share (which rate was 10.0% per year until the effective date of the Restated Charter on June 26, 2019) equal to $21.39 per share. On October 18, 2018, each holder of the Class B-1 Stock hereby irrevocably waived, all of its right, title and interest in and to 2.5% of the dividend rate, including without elimination all rights and entitlement to payment of such amounts. This partial dividend waiver resulted in a 7.5% effective rate per year of the Class B Liquidation Amount per share and was terminated upon the effectiveness of the Restated Charter. Dividends on the Class B Stock may also be paid by an in-kind distribution of additional shares of Class B Stock or any other class of shares of capital stock of BPR ranking junior to the Class A Stock. Dividends on the Class B Stock shall be cumulative and shall be payable quarterly in arrears, when, as and if declared by the Company's Board of Directors with respect to dividends on the Class B Stock. Holders of the Class B Stock are not entitled to receive dividends, redemptions or other distributions: (i) unless and until (a) BPR has paid the aggregate dividends owed to the holders of Class A Stock and (b) the dividend coverage ratio (as defined below) is equal to or greater than 1.25:1, (ii) if any tendering holder of Class A Stock has not received the cash or BPY units due upon exchange or (iii) if holders of Class A Stock are owed cash in the event of an adjustment to the conversion factor. The dividend coverage ratio is referred to as a ratio of (i) BPR’s funds from operations, as calculated in accordance with the definition of funds from operations used by the National Association of Real Estate Investment Trusts ("Nareit"), for the immediately preceding fiscal quarter, to (ii) the product of (a) the amount of the most recent regular quarterly distribution declared by BPY on each BPY unit, times (b) the number of shares of Class A Stock outstanding at such time. Series B Preferred Stock The following description sets forth certain general terms and provisions of the Series B Preferred Stock, par value $0.01 per share, of the Company (the "Series B Preferred Stock"). Pursuant to the Restated Charter and subject to the prior rights of holders of all classes, including the Class A Stock, Class B Stock and any series of preferred stock at the time outstanding having prior rights as to dividends, each share of Series B Preferred Stock will entitle its holder to cumulative dividends per share in a cash amount at a rate of 8.65% per year of the Class B liquidation amount per share (which rate was 10.0% until the effective date of the Restated Charter on June 26, 2019), with such Class B liquidation amount per share equal to $21.39 . Dividends on the Series B Preferred Stock may also be paid by an in-kind distribution of additional shares of Series B Preferred Stock or any other class of shares of capital stock of BPR ranking junior to the Class A Stock and Class B Stock. Dividends on the Series B Preferred Stock shall be cumulative and shall be payable quarterly in arrears, when, as and if declared by the Company's Board of Directors with respect to dividends on the Series B Preferred Stock. Holders of the Series B Preferred Stock are not entitled to receive dividends, redemptions or other distributions: (i) unless and until (a) BPR has paid the aggregate dividends owed to the holders of Class A Stock and Class B Stock and (b) the dividend coverage ratio (as defined below) is equal to or greater than 1.25:1, (ii) if any tendering holder of Class A Stock has not received the cash or BPY units due upon exchange or (iii) if holders of Class A Stock are owed cash in the event of an adjustment to the conversion factor. The dividend coverage ratio is referred to as a ratio of (i) BPR’s funds from operations, as calculated in accordance with the definition of funds from operations used by Nareit, for the immediately preceding fiscal quarter, to (ii) the product of (a) the amount of the most recent regular quarterly distribution declared by BPY on each BPY unit, times (b) the number of shares of Class A Stock outstanding at such time. Class C Stock Class C Stock refers to the Company's Class C Stock, par value $0.01 per share, authorized as part of the BPY Transaction. Pursuant to the amended charter and subject to the prior rights of holders of all classes, including the holders of Class A Stock, Class B Stock, Series B Preferred Stock and any series of preferred stock at the time outstanding having prior rights as to dividends, each share of Class C Stock will entitle its holder to dividends when, as and if declared by the Company's Board of Directors out of any assets of BPR legally available therefore. The record and payment date for dividends on shares of Class C Stock shall be such date that the Company's Board of Directors shall designate. Notwithstanding the foregoing, holders of the Class C Stock are not entitled to receive dividends, redemptions or other distributions: (i) unless and until (a) BPR has paid the aggregate dividends owed to the holders of Class A Stock and (b) the dividend coverage ratio is equal to or greater than 1.25:1, (ii) if any tendering holder of Class A Stock has not received the cash or BPY units due upon exchange, (iii) if holders of Class A Stock are owed cash in the event of an adjustment to the conversion factor or (iv) unless and until the full cumulative dividends on the Class B Stock and Series B Preferred Stock for all past dividend periods and any current dividend periods have been (or contemporaneously are) (a) declared or paid in cash or (b) declared and a sum sufficient for the payment thereof in cash is set apart for such payment.

Common Stock Dividends Our Board of Directors declared dividends on our common stock during 2018 as follows: Declaration Date (1) Record Date Payment Date Dividend Per Share 2018 May 3 July 13, 2018 July 31, 2018 $ 0.22 February 7 April 13, 2018 April 30, 2018 0.22 (1) Excludes the Pre-Closing Dividend ( Note 1 ). A Dividend Reinvestment Plan ("DRIP") provided eligible holders of GGP's common stock with a convenient method of increasing their investment in the Company by reinvesting all or a portion of cash dividends in additional shares. Pursuant to the DRIP, eligible stockholders who enrolled in the DRIP on or before the four th business day preceding the record date for a dividend payment were able to have that dividend reinvested. The Company terminated the registration statement relating to our DRIP (File No. 333-172795) with the filing of a post-effective amendment on August 28, 2018. As a result of the DRIP elections, no shares were issued pursuant to the DRIP during the year ended December 31, 2019 and year ended December 31, 2018 . Preferred Stock On February 13, 2013, we issued, in a public offering, 10,000,000 shares of 6.375% Series A Cumulative Redeemable Preferred Stock (the "Pre-Merger Preferred Stock") at a price of $25.00 per share, resulting in net proceeds of $242.0 million after issuance costs. In connection with the BPY Transaction, each share of Pre-Merger Preferred Stock was converted into one share of 6.375% Series A cumulative redeemable preferred stock of BPR (the "Series A Preferred Stock"). The Series A Preferred Stock is recorded net of issuance costs within equity on our Consolidated Balance Sheets, and accrues a quarterly dividend at an annual rate of 6.375% . The dividend is paid in arrears in preference to dividends on our Class A Stock, and reduces net income available to common stockholders, and therefore, earnings per share. Preferred stock dividends were $15.9 million for the years ended December 31, 2019 , December 31, 2018 and December 31, 2017 . The Series A Preferred Stock does not have a stated maturity date but we may redeem the Series A Preferred Stock for $25.00 per share plus all accrued and unpaid dividends. Upon certain circumstances surrounding a change of control, holders of Series A Preferred Stock may elect to convert each share of their Series A Preferred Stock into a number of shares of Class A Stock or Class C Stock, at the option of the holder, equivalent to $25.00 plus accrued and unpaid dividends, but not to exceed a cap of 2.4679 shares of Class A Stock or Class C Stock (subject to certain adjustments related to splits, subdivisions, or combinations). The BPY Transaction did not meet the definition of a change in control per the certificate of designation governing the Series A Preferred Stock. Our Board of Directors declared preferred stock dividends during 2019 and 2018 as follows: Declaration Date Record Date Payment Date Dividend Per Share 2019 November 4 December 13, 2019 January 1, 2020 $ 0.3984 August 1 September 13, 2019 October 1, 2019 0.3984 May 6 June 14, 2019 July 1, 2019 0.3984 February 6 March 15, 2019 April 1, 2019 0.3984 2018 November 1 December 14, 2018 January 1, 2019 $ 0.3984 July 31 September 17, 2018 October 1, 2018 0.3984 May 3 June 15, 2018 July 2, 2018 0.3984 February 7 March 15, 2018 April 2, 2018 0.3984

EARNINGS PER SHARE

EARNINGS PER SHARE	12 Months Ended

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE Class A Stock Income available to Class A stockholders is limited to distributed income or dividends declared. Additionally, for purposes of allocating earnings to Class A Stock, the portion of the change in the carrying amount of Class A Stock that reflects a redemption in excess of fair value is considered a dividend to the Class A stockholders. As the Class A Stock redemption value approximates its fair value, basic and diluted earnings per share ("EPS") for Class A Stock is equivalent to the dividends declared for the year ended December 31, 2019 . Shares of Class A Stock outstanding were 64,024,422 and 109,804,513 as of December 31, 2019 and 2018, respectively. EPS is not presented for Class B Stock and Class C Stock as neither class of stock is publicly traded. Common Stock In 2018, basic EPS for common stock was computed by dividing net income available to common stockholders by the weighted-average number of GGP common shares outstanding. Diluted EPS for common stock was computed after adjusting the numerator and denominator of the basic EPS computation for the effects of all potentially dilutive common shares. The dilutive effect of the Warrants and the dilutive effect of options and their equivalents (including fixed awards and nonvested stock issued under stock-based compensation plans), were computed using the "treasury" method. The dilutive effect of the Preferred Units is computed using the "if-converted" method. Information related to our EPS calculations is summarized as follows: January 1, 2018 through August 27, 2018 Numerators - Basic: Net income $ 3,860,424 Preferred Stock dividends (11,952 ) Allocation to noncontrolling interests (43,049 ) Net income attributable to common stockholders $ 3,805,423 Numerators - Diluted: Distributions to Preferred Units 1,711 Net income attributable to common stockholders $ 3,807,134 Denominators: Weighted-average number of common shares outstanding - basic 914,066 Effect of dilutive securities 3,831 Weighted-average number of common shares outstanding - diluted 917,897 Anti-dilutive Securities: Effect of Common Units 7,662 Effect of LTIP Units 1,748 Weighted-average number of anti-dilutive securities 9,410 Year Ended December 31, 2017 Numerators—Basic: Net income $ 666,873 Preferred Stock dividend (15,936 ) Allocation to noncontrolling interests (9,539 ) Net income attributable to common stockholders $ 641,398 Numerators—Diluted: Net income attributable to common stockholders $ 641,398 Diluted net income attributable to common stockholders $ 641,398 Denominators: Weighted-average number of common shares outstanding—basic 897,156 Effect of dilutive securities 50,403 Weighted-average number of common shares outstanding—diluted 947,559 Anti-dilutive Securities: Effect of Preferred Units 1,514 Effect of Common Units 6,592 Effect of LTIP Units 1,836 9,942 For the period January 1, 2018 through August 27, 2018, dilutive options and dilutive shares related to the Preferred Units were included in the denominator of dilutive EPS. Distributions to Preferred Units were included in the numerator of dilutive EPS. For the year ended December 31, 2018 , dilutive options and dilutive shares related to the warrants were included in the denominator of diluted EPS. For the year ended December 31, 2017, dilutive options and dilutive shares related to the warrants are included in the denominator of diluted EPS. Outstanding Common Units and LTIP Units have been excluded from the diluted earnings per share calculation because including such units would also require that the share of BPROP income attributable to such units be added back to net income therefore resulting in no effect on EPS. For the year ended December 31, 2017, outstanding Preferred Units have been excluded from the diluted EPS calculation for all periods presented because including the Preferred Units would also require that the Preferred Units dividend be added back to the net income, resulting in anti-dilution. During the year ended December 31, 2017, Warrants were exercised for 83,866,187 shares of common stock using both full and net share settlement. BPY owned 55,969,390 shares of treasury stock of GGP as of December 31, 2017. These shares are presented as common stock in treasury, at cost, on our Consolidated Balance Sheet. Additionally, BPR Nimbus LLC, (formerly known as GGP Nimbus, LP), held 27,459,195 shares of stock as a result of warrants purchased during the year ended December 31, 2013. These shares are presented as issued, but not outstanding on our Consolidated Balance Sheet as of December 31, 2017. Accordingly, these shares have been excluded from the calculation of EPS.

Share-based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION PLANS	STOCK-BASED COMPENSATION PLANS Incentive Stock Plans The GGP Inc. 2010 Equity Plan (the "Equity Plan") renamed as the Amended and Restated Brookfield Property REIT Inc. 2010 Equity Incentive Plan on August 28, 2018 in connection with the BPY Transaction, reserves for the issuance of 4% of outstanding Class A Stock on a fully diluted basis. The Equity Plan provides for grants of nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock, other stock-based awards and performance-based compensation (collectively, "the Awards"). The Company's directors, officers and other employees and those of its subsidiaries and affiliates are eligible for the Awards. The Equity Plan is not subject to the Employee Retirement Income Security Act of 1974, as amended. No participant may be granted more than 4,000,000 shares, or the equivalent dollar value of such shares, in any year. Options granted under the Equity Plan will be designated as either nonqualified stock options or incentive stock options. An option granted as an incentive stock option will, to the extent it fails to qualify as an incentive stock option, be treated as a nonqualified option. The exercise price of an option may not be less than the fair value of a share of BPR's Class A Stock on the date of grant. The term of each option will be determined prior to the date of grant, but may not exceed 10 years. In connection with the BPY Transaction, the Company's Equity Plan was amended and certain outstanding awards were modified. All outstanding GGP in and out of the money options were canceled and replaced with Class A Stock of BPR and BPY options, respectively. Certain existing appreciation only LTIP awards were canceled and replaced with substitute awards of a BPY affiliate. Outstanding restricted GGP shares were replaced with restricted shares of Class A Stock. As the awards were modified in conjunction with an equity restructuring, they were accounted for as modifications. Incremental compensation cost was measured as the excess of the fair value of the replacement awards over the fair value of the original awards immediately before the terms were modified. Total compensation cost measured at the date of modification was the grant-date fair value of the original awards for which the requisite service is expected to be rendered (or has already been rendered) plus the incremental cost associated with the replacement awards. For vested awards, incremental compensation cost was recognized on the modification date. For unvested awards, incremental compensation cost is being recognized over the remaining service period. Stock Options Stock options under the Equity Plan generally vest in 25% increments annually from one year from the grant date (subject to certain exceptions in the case of retirement).

A portion of the shares vest either immediately or on the first anniversary and the remainder vest in equal annual amounts over the next two to four years . Participating employees are required to remain employed for vesting to occur (subject to certain exceptions in the case of retirement). LTIP Units are classes of partnership interests that under certain conditions, including vesting, are convertible by the holder into units of BPROP Series K preferred stock of the Operating Partnership, which are redeemable by the holder for shares of Class A stock on a one-to-one ratio (subject to adjustment for changes to the Company's capital structure) or for the cash value of such shares at the option of the Company.

Performance Equity Compensation Pursuant to the Equity Plan, GGP made performance restricted stock and LTIP Unit ("equity performance instruments") grants to certain employees. These grants are subject to certain performance vesting conditions based on Relative TSR of the Equity REIT Index, Relative TSR of the Retail REIT Index, TSR growth of the company, and FFO Growth of the company. The equity performance instruments are considered earned based on meeting these performance vesting conditions, which are each weighted 25% and vest at the end of the three-year performance period. The LTIP Units receive dividends at a ratio of 10% cash and 90% as a dividend reinvestment which is subject to the performance vesting conditions and three-year performance period. As a result of the BPY Transaction, all performance metrics were deemed met with outstanding awards still requiring time vesting according to original grant terms.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The accompanying consolidated financial statements include the accounts of BPR, our subsidiaries and joint ventures in which we have a controlling interest. For consolidated joint ventures, the noncontrolling partner's share of the assets, liabilities and operations of the joint ventures (generally computed as the joint venture partner's ownership percentage) is included in noncontrolling interests in consolidated real estate affiliates as permanent equity of the Company. Intercompany balances and transactions have been eliminated. Noncontrolling interests are included on our Consolidated Balance Sheets related to the Common, Preferred, and LTIP Units of BPROP and are presented either as redeemable noncontrolling interests or as noncontrolling interests in our permanent equity. The Operating Partnership and each of our consolidated joint ventures are variable interest entities as the limited partners do not have substantive kick-out rights or substantive participating rights. However, as the Company holds a majority voting interest in the Operating Partnership and our consolidated joint ventures, it qualifies for the exemption from providing certain of the disclosure requirements associated with variable interest entities.
Properties	Properties Real estate assets are stated at cost less any provisions for impairments. Expenditures for significant betterments and improvements are capitalized. Maintenance and repairs are charged to expense when incurred. Construction and improvement costs incurred in connection with the development of new properties or the redevelopment of existing properties are capitalized. Real estate taxes, interest costs, and initial direct costs associated with leasing and development overhead incurred during construction periods are capitalized. Capitalization is based on qualified expenditures and interest rates. Capitalized real estate taxes, interest costs, and initial direct costs associated with leasing and development overhead are amortized over lives which are consistent with the related assets. Pre-development costs, which generally include legal and professional fees and other third-party costs directly related to the construction assets, are capitalized as part of the property being developed. In the event a development is no longer deemed to be probable of occurring, the capitalized costs are expensed (see also our impairment policies in this note below). We periodically review the estimated useful lives of our properties, and may adjust them as necessary. The estimated useful lives of our properties range from 10 - 45 years. Depreciation or amortization expense is computed using the straight-line method based upon the following estimated useful lives: Years Buildings and improvements 10 - 45 Equipment and fixtures 3 - 20 Tenant improvements Shorter of useful life or applicable lease term
Acquisitions of Operating Properties (Note 3)	useful lives: Years Buildings and improvements 10 - 45 Equipment and fixtures 3 - 20 Tenant improvements Shorter of useful life or applicable lease term Reclassifications The reclassifications presented in the table below are the result of the Company's adoption of the new accounting guidance for lease accounting, Accounting Standards Codification (ASC) 842, Leases, ("ASC 842" or "the new leasing standard") on January 1, 2019. As part of that adoption, the Company elected the available practical expedient, for all classes of assets, not to separate lease components in contracts from the nonlease components in those contracts, when recording revenues associated with operating leases where it is the lessor. Since the lease component is the predominant component under the Company's leases, combined revenues from both the lease and nonlease components are accounted for in accordance with ASC 842. Components of revenue that were previously reported as minimum rents, tenant recoveries, and overage rents have been combined and reported as rental revenues on the Consolidated Statements of Operations and Comprehensive Income. The presentation and disclosure of rental revenues have been adjusted to reflect these changes for the year ended December 31, 2019. Total revenues of the Company are unchanged by this reclassification. Refer to Note 7 for further information. Year Ended December 31, 2018 Year Ended December 31, 2017 As Originally Reported As Reclassified As Originally Reported As Reclassified Minimum rents $ 1,297,945 $ — $ 1,455,039 $ — Tenant recoveries 540,376 — 643,607 — Overage rent 29,659 — 34,874 — Total rental revenues $ — $ 1,867,980 $ — $ 2,133,520 Acquisitions of Operating Properties ( Note 3 ) Acquisitions of properties are typically accounted for as acquisitions of assets rather than acquisitions of a business. Accordingly, the results of operations of acquired properties have been included in the results of operations from the respective dates of acquisition and acquisition costs are capitalized. Estimates of future cash flows and other valuation techniques are used to allocate the purchase price of acquired property between land, buildings and improvements, equipment, assumed debt liabilities and identifiable intangible assets and liabilities such as amounts related to in-place tenant leases, acquired above and below-market tenant and ground leases, and tenant relationships. The fair values of tangible assets are determined on an "if vacant" basis. The "if vacant" fair value is allocated to land, where applicable, buildings, equipment and tenant improvements based on comparable sales and other relevant information with respect to the property. Specifically, the "if vacant" value of the buildings and equipment was calculated using a cost approach utilizing published guidelines for current replacement cost or actual construction costs for similar, recently developed properties; and an income approach. Assumptions used in the income approach to the value of buildings include: capitalization and discount rates, lease-up time, market rents, make ready costs, land value, and site improvement value. The estimated fair value of in-place tenant leases includes lease origination costs (the costs we would have incurred to lease the property to the current occupancy level of the property) and the lost revenues during the period necessary to lease-up from vacant to the current occupancy level. Such estimates include the fair value of leasing commissions, legal costs and tenant coordination costs that would be incurred to lease the property to this occupancy level. Additionally, we evaluate the time period over which such occupancy level would be achieved and include an estimate of the net operating costs (primarily real estate taxes, insurance and utilities) incurred during the lease-up period, which generally ranges up to one year . The fair value of acquired in-place tenant leases is included in the balance of buildings and equipment and amortized over the remaining lease term for each tenant. Identifiable intangible assets and liabilities are calculated for above-market and below-market tenant and ground leases where we are either the lessor or the lessee. The difference between the contractual rental rates and our estimate of market rental rates is measured over a period equal to the remaining non-cancelable term of the leases, including significantly below-market renewal options for which exercise of the renewal option appears to be reasonably assured. The remaining term of leases with renewal options at terms significantly below market reflect the assumed exercise of such below-market renewal options and assume the amortization period would coincide with the extended lease term.
Investments in Unconsolidated Real Estate Affiliates (Note 6)	Investments in Unconsolidated Real Estate Affiliates ( Note 5 ) We account for investments in joint ventures where we own a non-controlling joint interest using either the equity method or the cost method. If we have significant influence but not control over the investment, we utilize the equity method. If we have neither control nor significant influence, we utilize the cost method. Under the equity method, the cost of our investment is adjusted for our share of the earnings of such Unconsolidated Real Estate Affiliates from the date of acquisition, increased by our contributions and reduced by distributions received. Under the cost method, the cost of our investment is not adjusted for our share of the earnings of such Unconsolidated Real Estate Affiliates from the date of acquisition and distributions are treated as earnings when received. To determine the method of accounting for partially owned joint ventures, we evaluate the characteristics of associated entities and determine whether an entity is a variable interest entity ("VIE"). A limited partnership or other similar entity is considered a VIE unless a simple majority of limited partners (excluding limited partners that are under common control with the general partner) have substantive kick-out rights or participating rights. If an entity is determined to be a VIE, we determine which party is the primary beneficiary by analyzing whether we have both the power to direct the entity's significant economic activities and the obligation to absorb potentially significant losses or receive potentially significant benefits. Significant judgments and assumptions inherent in this analysis include the nature of the entity's operations, future cash flow projections, the entity's financing and capital structure, and contractual relationship and terms. Primary risks associated with our VIEs include the potential of funding the entities' debt obligations or making additional contributions to fund the entities' operations. Generally, the operating agreements with respect to our Unconsolidated Real Estate Affiliates provide that assets, liabilities and funding obligations are shared in accordance with our ownership percentages. Therefore, we generally also share in the profit and losses, cash flows and other matters relating to our Unconsolidated Real Estate Affiliates in accordance with our respective ownership percentages. Except for Retained Debt (as described in Note 5 ), differences between the carrying amount of our investment in the Unconsolidated Real Estate Affiliates and our share of the underlying equity of our Unconsolidated Real Estate Affiliates are typically amortized over lives ranging from 5 to 45 years. When cumulative distributions exceed our investment in the joint venture, the investment is reported as a liability in our consolidated financial statements. The liability is limited to our maximum potential obligation to fund contractual obligations, including recourse related to certain debt obligations. Partially owned joint ventures over which we have controlling financial interest are consolidated in our consolidated financial statements. In determining if we have a controlling financial interest, we consider factors such as ownership interest, authority to make decisions, kick-out rights and substantive participating rights. Partially owned joint ventures where we do not have a controlling financial interest, but have the ability to exercise significant influence, are accounted for using the equity method. To the extent that we contribute assets to a joint venture accounted for using the equity method, our investment in the joint venture is recorded at the fair value of the consideration of the assets that were contributed to the joint venture. We will recognize gains and losses on the contribution of our real estate to joint ventures, relating to our entire investment in the property, to the extent the buyer is independent of the Company, the collection of the sales price is reasonably assured, and we will not be required to support the operations of the property or its related obligations to an extent greater than our proportionate interest. The combined summarized financial information of unconsolidated joint ventures is disclosed in Note 5 to the Consolidated Financial Statements.
Cash and Cash Equivalents	Cash and Cash Equivalents Highly-liquid investments with initial maturities of three months or less are classified as cash equivalents, excluding amounts restricted by certain lender and other agreements.
Lessee, Leases	Leases ( Note 7 ) We have entered into lease arrangements for the land and buildings at certain properties, as well as for the use of office space in Chicago, Illinois. We account for leases under ASC 842, Leases ("the new leasing standard"). We elected to use the "package of practical expedients", as discussed below, which allowed us not to reassess under the new leasing standard prior conclusions about lease identification, lease classification, and initial direct costs. We elected to recast prior-period comparative information presented in our Consolidated Statements of Operations and Comprehensive Income related to rental revenues. The new leasing standard requires lessees to record a right-of-use ("ROU") asset and a related lease liability for the rights and obligations associated with all lessee leases. ASC 842 also modified the lease classification criteria through the elimination of "bright-line" tests, the removal of historical real estate specific lease provisions, and changes to lessor accounting to align with the new revenue recognition standard ASC 606, Revenue from Contracts with Customers . On the adoption date, we recognized lease liabilities of $73.4 million and ROU assets of $118.9 million for operating leases of Consolidated Properties for which we are the lessee included in accounts payable and accrued expenses and prepaid expenses and other assets, respectively, on the Consolidated Balance Sheet and there was no cumulative effect on retained earnings. In order to determine the lease liabilities recognized upon adoption, we discounted the remaining lease payments using our incremental borrowing rates ("IBR") at January 1, 2019. The weighted average rate applied was 7.36% . The ROU asset balance was initially measured as the lease liability amount adjusted by the amount of prepaid or accrued lease payments, deferred straight-line lease liabilities, and intangible ground lease assets and liabilities relating to leases recognized on our Consolidated Balance Sheet as of December 31, 2018. In transition, an adjustment of $45.4 million was made to the ROU asset balance to derecognize $52.8 million of below-market ground lease intangible assets (within prepaid expenses and other assets) and $7.4 million of accrued straight-line rent (within accounts payable and accrued expenses) which are now part of the total ROU assets previously recorded on our Consolidated Balance Sheet. In addition to the "package of practical expedients", we elected to use the following additional practical expedients permitted by the new leasing standard: • The transition practical expedient that allows us to carry forward our historical accounting treatment for land easements on existing agreements. • The short-term lease election that allows a lessee not to apply the balance sheet recognition requirements to leases with a term of 12 months or less; lease payments associated with these leases are recognized on a straight-line basis as an expense over the lease term and are not material. • The practical expedient which allows a lessee to not separate lease and non-lease components. We have elected to apply this election to all classes of underlying assets. • The Company did not elect to apply the practical expedients related to hindsight or assessing impairment of ROU assets. Lessee arrangements To account for leases for which we are the lessee under the new leasing standard, contracts must be analyzed upon inception to determine if the arrangement is, or contains, a lease. A lease conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Lease classification tests and measurement procedures are performed at the lease commencement date. Differences in lease classification will affect only the pattern and classification of expense recognition in our Consolidated Statements of Operations and Comprehensive Income. The lease liability is initially measured as the present value of the lease payments over the lease term, discounted using the interest rate implicit in the lease, if that rate is readily determinable; otherwise, the lessee’s incremental borrowing rate is used. The lease liability balance is subsequently amortized using the effective interest method. The incremental borrowing rate is determined using an approach based on the rate of interest that the lessee would pay to borrow on a collateralized basis over a similar term at an amount equal to the lease payments in a similar economic environment. We utilized a market-based approach to estimate the IBR for each individual lease. Therefore, we utilized different data sets to estimate base IBRs via an analysis of (i) yields on outstanding public debt of BPR, as well as comparable companies, (ii) observable mortgage rates, and (iii) unlevered property yields and discount rates. We then applied adjustments to account for considerations related to (i) term and (ii) security that may not be fully incorporated by the aforementioned data sets. Based on individual characteristics of each lease, we selected an IBR taking into consideration how each data approach and adjustments thereto incorporate term, currency and security. The lease term is the noncancelable period of the lease, and includes any renewal and termination options we are reasonably certain to exercise. The reasonably certain threshold is evaluated at lease commencement and is typically met if substantial economic incentives or termination penalties are identified. Lease payments measured at the commencement date include fixed payments, in-substance fixed payments, variable lease payments dependent on a rate or index (using the index or rate in effect at lease commencement), any purchase option the lessee is reasonably certain to exercise, and payments of penalties for terminating the lease if the lease term reflects the lessee exercising the termination option. Fully variable lease payments without an in-substance fixed component are not included in the measurement of the lease liability and are recognized in the period in which the underlying contingency is resolved. The lease liability is remeasured when the contract is modified, upon the resolution of a contingency such that variable payments become fixed or if our assessment of exercising an extension, termination or purchase option changes. Once remeasured, an adjustment is made to the ROU asset. However, if the carrying amount of the right-of-use asset is reduced to zero, any remaining amount of the remeasurement is recognized in earnings. The ROU asset balance is initially measured as the lease liability amount, adjusted for any lease payments made prior to the commencement date, initial direct costs, estimated costs to dismantle, remove, or restore the underlying asset and incentives received. Our current lessee lease portfolio is comprised primarily of operating leases. If we enter into a finance lease, the new leasing standard requires us to initially recognize and measure these leases using the same method as described above for operating leases. Subsequent to initial recognition, each lease payment would be allocated between interest expense and a reduction of the lease liability. This expense would be recognized over the lease term using the interest method to produce a constant periodic rate of interest on the remaining balance of the liability for each period and would be included in interest expense in our Consolidated Statements of Operations and Comprehensive Income. The ROU asset would be amortized on a straight-line basis over the lease term, with depreciation recorded in depreciation and amortization in our Consolidated Statements of Operations and Comprehensive Income. The ROU assets in our operating leases are evaluated for impairment in a manner similar to our operating properties, as described below under "Impairment". Lessor arrangements At the inception of a new lease arrangement, including new leases that arise from amendments, we assess the terms and conditions to determine the proper lease classification. When the terms of a lease effectively transfer control of the underlying asset, the lease is classified as a sales-type lease. When a lease does not effectively transfer control of the underlying asset to the lessee, but we obtain a guarantee for the value of the asset from a third party, we classify the lease as a direct financing lease. All other leases are classified as operating leases. Control of the underlying asset is transferred to the lessee if any of the following criteria are met: (i) transfer of ownership to the lessee prior to or shortly after the end of the lease term, (ii) lessee has an option to purchase the underlying property that the lessee is reasonably certain to exercise, (iii) the lease term is for the major part of the underlying property’s remaining economic life, (iv) the present value of the sum of lease payments and any residual value guaranteed by the lessee that is not already reflected in the lease payments is equal to or exceeds substantially all of the fair value of the leased property or (v) the underlying property is of such a specialized nature that it is expected to have no alternative use at the end of the lease term. As of December 31, 2019, we do not have any material sales-type or direct financing leases. For operating leases with minimum scheduled rent increases, we recognize rental income on a straight‑line basis, including the effect of any free rent periods, over the lease term when collectability of lease payments (and, if applicable, any amounts necessary to satisfy a residual value guarantee) is probable. Variable lease payments are recognized as rental income in the period when the changes in facts and circumstances on which the variable lease payments are based occur. Variable lease payments include overage rent, which is paid by a tenant when the tenant's sales exceed an agreed upon minimum amount, is recognized once tenant sales exceed contractual tenant lease thresholds and is calculated by multiplying the sales in excess of the minimum amount by a percentage defined in the lease. Our leases also contain provisions for tenants to reimburse us for real estate taxes and insurance, as well as for other property operating expenses, marketing costs, and utilities, which are considered to be non-lease components. These tenant reimbursements are most often established in the leases or in less frequent cases computed based upon a formula. W e have elected the practical expedient to not separate non-lease components from the lease component for all classes of underlying assets and determined that the lease component is the predominant component in the contract; therefore, these recoveries are recognized in a manner similar to minimum rents and variable rents within rental revenues on our Consolidated Statements of Operations and Comprehensive Income. Recognizing rental and related income on a straight-line basis results in a difference in the timing of revenue recognition from what is contractually due from tenants. Straight-line rents are recorded in accounts receivable, net in our Consolidated Balance Sheet. For leases where collectability of the lease payments is probable, we establish a general allowance for doubtful accounts against the portion of accounts receivable, net, including straight-line rents, which is estimated to be uncollectible based on our previous recovery experience. Changes in the general allowance are recognized in rental income on our Consolidated Statements of Operations and Comprehensive Income. If we determine that collectability of the lease payments is not probable, we record a current-period adjustment to rental income to reduce cumulative income recognized since lease commencement to the amount of cash collected from the lessee. Future revenue recognition is limited to amounts paid by the lessee . Generally, a lease is returned to accrual status when all delinquent payments become current under the terms of the lease agreement and collectability of the remaining contractual lease payments is reasonably probable. Rental revenues also includes lease termination income collected from tenants to allow for the tenant to vacate their space prior to their scheduled termination dates, as well as accretion related to above-market and below-market tenant leases on acquired properties and properties that were recorded at fair value at the emergence from bankruptcy. In leasing tenant space, we may provide funding to the lessee through a tenant allowance. To account for a tenant allowance, we determine whether the allowance represents funding for the construction of leasehold improvements and evaluate the control and ownership of such improvements. If we are considered the owner of the leasehold improvements, we capitalize the amount of the tenant allowance and depreciate it over the shorter of the useful life of the leasehold improveme nts or the related lease term. If the tenant allowance represents a payment for a purpose other than funding leasehold improvements, or in the event we are not considered the owner of the leasehold improvements, the allowance is capitalized to deferred expenses and considered to be a lease incentive and is recognized over the lease term as a reduction of rental revenue on a straight-line basis. The following is a summary of amortization of straight-line rent, net amortization/accretion related to above-market and below-market tenant leases and termination income, which is included in rental revenues: Year Ended December 31, 2019 2018 2017 Amortization of straight-line rent $ 8,488 $ (2,425 ) $ 2,084 Net amortization/accretion of above and below-market tenant leases 22,037 (3,259 ) (23,963 ) Lease termination income 13,235 31,297 29,081 The following is a summary of straight-line rent receivables, which are included in accounts receivable, net in our Consolidated Balance Sheets and are reduced for allowances and amounts doubtful of collection: December 31, 2019 December 31, 2018 Straight-line rent receivables, net $ 142,791 $ 136,007 Deferred expenses The new leasing standard defines initial direct costs as incremental costs of a lease that would not have been incurred if the lease had not been obtained. These initial direct costs (consisting primarily of leasing commissions paid to third parties) are recognized as deferred expenses on our Consolidated Balance Sheet and are amortized using the straight-line method over the life of the leases. Other leasing costs which do not meet the definition of initial direct costs (consisting primarily of internal legal and leasing overhead costs) are expensed as incurred and included in property management and other costs in our Consolidated Statements of Operations and Comprehensive Income.
Deferred Expenses	Deferred Expenses Deferred expenses primarily consist of leasing commissions and related costs and are amortized using the straight-line method over the life of the leases.
Revenue Recognition and Related Matters	Revenue Recognition and Related Matters Accounting for real estate sales distinguishes between sales to a customer or non-customer for purposes of revenue recognition. Once we, as the seller, determine that we have a contract, we will identify each distinct non-financial asset promised to the counter-party and whether the counter-party obtains control and transfers risks and rewards of ownership of each non-financial asset to determine if we should derecognize the asset. Notes receivable are evaluated for impairment at least quarterly. Impairment occurs when it is deemed probable that we will not be able to collect all amounts due according to the contractual terms of the loan. If a loan is considered to be impaired, we record an allowance through the provision for loan losses to reduce the carrying value of the loan to the present value of expected future cash flows discounted at the loan’s contractual effective rate or the fair value of the collateral, if repayment is expected solely from the collateral.
Management Fees and Other Corporate Revenues	Management Fees and Other Corporate Revenues Management fees and other corporate revenues primarily represent real estate management and leasing fees, development fees, financing fees and fees for other ancillary services performed for the benefit of certain of the Unconsolidated Real Estate Affiliates. Management fees are reported at 100% of the revenue earned from the joint venture in management fees and other corporate revenues on our Consolidated Statements of Operations and Comprehensive Income. Our share of the management fee expense incurred by the Unconsolidated Real Estate Affiliates is reported within equity in income of Unconsolidated Real Estate Affiliates on our Consolidated Statements of Operations and Comprehensive Income and in property management and other costs in the Condensed Combined Statements of Income in Note 5 .
Income Taxes (Note 8)	Income Taxes ( Note 8 ) We expect to distribute 100% of our taxable capital gains and taxable ordinary income to stockholders annually. If, with respect to any taxable year, we fail to maintain our qualification as a REIT and cannot correct such failure, we would not be allowed to deduct distributions to stockholders in computing our taxable income and federal income tax. If any of our REIT subsidiaries fail to qualify as a REIT, such failure could result in our loss of REIT status. If we lose our REIT status, corporate level income tax would apply to our taxable income at regular corporate rates. As a result, the amount available for distribution to holders of equity securities that would otherwise receive dividends would be reduced for the year or years involved, and we would no longer be required to make distributions. In addition, unless we were entitled to relief under the relevant statutory provisions, we would be disqualified from treatment as a REIT for four subsequent taxable years. Deferred income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the financial statements or tax returns and are recorded primarily by certain of our taxable REIT subsidiaries. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Deferred income taxes also reflect the impact of operating loss and tax credit carryforwards. A valuation allowance is provided if we believe it is more likely than not that all or some portion of the deferred tax asset will not be realized. An increase or decrease in the valuation allowance that results from a change in circumstances, and which causes a change in our judgment about the realizability of the related deferred tax asset, is included in the current tax provision. In addition, we recognize and report interest and penalties, if necessary, related to uncertain tax positions within our provision for income tax expense. We earn investment tax credits related to solar projects at certain properties. We use the flow through method of accounting for investment tax credits. Under this method, investment tax credits are recognized as a reduction to income tax expense in the year they are earned.
Impairment	hey are earned. Impairment Operating Properties We regularly review our consolidated properties for potential impairment indicators whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Impairment indicators are assessed separately for each property and include, but are not limited to, significant decreases in real estate property net operating income, significant decreases in occupancy percentage, debt maturities, changes in management's intent with respect to the properties and prevailing market conditions. If an indicator of potential impairment exists, the property is tested for recoverability by comparing its carrying amount to the estimated future undiscounted cash flows. Although the carrying amount may exceed the estimated fair value of certain properties, a real estate asset is only considered to be impaired when its carrying amount cannot be recovered through estimated future undiscounted cash flows. To the extent an impairment provision is determined to be necessary, the excess of the carrying amount of the property over its estimated fair value is expensed to operations. In addition, the impairment provision is allocated proportionately to adjust the carrying amount of the asset group. The adjusted carrying amount, which represents the new cost basis of the property, is depreciated over the remaining useful life of the property. Although we may market a property for sale, there can be no assurance that the transaction will be complete until the sale is finalized. However, GAAP requires us to utilize the Company's expected holding period of our properties when assessing recoverability. If we cannot recover the carrying value of these properties within the planned holding period, we will estimate the fair values of the assets and record impairment charges for properties when the estimated fair value is less than their carrying value. Impairment indicators for pre-development costs, which are typically costs incurred during the beginning stages of a potential development and construction in progress, are assessed by project and include, but are not limited to, significant changes in the Company's plans with respect to the project, significant changes in projected completion dates, tenant demand, anticipated revenues or cash flows, development costs, market factors and sustainability of development projects. Impairment charges are recorded in the Consolidated Statements of Operations and Comprehensive Income when the carrying value of a property is not recoverable and it exceeds the estimated fair value of the property, which can occur in accounting periods preceding disposition and/or in the period of disposition. During the year ended December 31, 2019 , we recorded a $223.1 million impairment charge on our Consolidated Statements of Operations and Comprehensive Income, $184.3 million of which related to one operating property as a result of a significant decrease in market leasing assumptions and $38.8 million of which related to the impairment charge on one operating property where the carrying value exceeded the transfer price to our affiliate ( Note 3 ). During the year ended December 31, 2018 , we recorded a $45.9 million impairment charge on our Consolidated Statements of Operations and Comprehensive Income related to one operating property that had non-recourse debt maturing during 2019 that exceeded the fair value of the operating property. The property was conveyed to the lender in full satisfaction of the debt on November 1, 2018. No provisions for impairment were recognized during the year ended December 31, 2017 . Changes in economic and operating conditions that occur subsequent to our review of recoverability of our properties could impact the assumptions used in that assessment and could result in future impairment if assumptions regarding those properties differ from actual results. Investment in Unconsolidated Real Estate Affiliates
Property Management and Other and General and Administrative Costs	otes Receivable Notes receivable are evaluated for impairment at least quarterly. Impairment occurs when it is deemed probable that we will not be able to collect all amounts due according to the contractual terms of the loan. If a loan is considered to be impaired, we record an allowance through the provision for loan losses to reduce the carrying value of the loan to the present value of expected future cash flows discounted at the loan’s contractual effective rate or the fair value of the collateral, if repayment is expected solely from the collateral. No impairments related to our notes receivable were recognized for the years ended December 31, 2019, 2018 and 2017. Property Management and Other and General and Administrative Costs Property management and other costs represent regional and home office costs and include items such as corporate payroll, rent for office space, supplies and professional fees, which represent corporate overhead costs not generated at the properties. General and administrative costs represent the costs to run the public company and include payroll and other costs for employees, audit fees, professional fees and administrative fees related to the public company.
Fair Value Measurements (Note 5)	Fair Value Measurements ( Note 4 ) The accounting principles for fair value measurements establish a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: • Level 1 - defined as observable inputs such as quoted prices for identical assets or liabilities in active markets; • Level 2 - defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and • Level 3 - defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The impairment section above includes a discussion of all impairments recognized during the years ended December 31, 2019 , 2018 and 2017 , which were based on Level 2 and Level 3 inputs. Note 4 includes a discussion of properties measured at fair value on a non-recurring basis using Level 2 and Level 3 inputs and the fair value of debt, which is estimated on a recurring basis using Level 2 and Level 3 inputs. Note 3 discusses certain asset acquisition transactions that required fair value measurements related to equity method investments and acquired interests that were valued on a non-recurring basis using Level 3 inputs. Note 10 includes a discussion of certain redeemable noncontrolling interests that are measured at fair value using Level 1 inputs.
Concentration of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and cash equivalents. We are exposed to credit risk with respect to cash held at various financial institutions and access to our credit facility. Our credit risk exposure with regard to our cash and the $1.5 billion available under our credit facility is spread among a diversified group of investment grade financial institutions. We had $715.0 million and $387.0 million outstanding under our credit facility as of December 31, 2019 and 2018 , respectively.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Effective January 1, 2018, companies were required to apply a five-step model in accounting for revenue. The core principle of the revenue model is that a company recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Lease contracts are excluded from this revenue recognition criteria; however, the sale of real estate is required to follow the new model. Expanded quantitative and qualitative disclosures regarding revenue recognition are required for contracts that are subject to this pronouncement. The new standard could be adopted either retrospectively to each prior reporting period presented or on a modified retrospective approach as a cumulative effect adjustment as of the date of adoption. The Company adopted the model effective January 1, 2018 using the modified retrospective approach for implementation. The Company elected to use the practical expedient to apply the model only to contracts not yet completed as of the date of adoption. The adoption resulted in a cumulative-effect adjustment to increase equity as of January 1, 2018 of approximately $1.90 million related to changes in the revenue recognition pattern of lease commissions earned by the Company from our joint ventures and the sale of condos in our Unconsolidated Real Estate Affiliates ( Note 5 ). Based upon the new revenue recognition guidance, revenue recognized for the year ended December 31, 2018 is not significantly different as compared to what would have been recognized in the same period under guidance that was in effect before the change. In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, Leases . This new guidance, including related ASUs that have been subsequently issued, was effective January 1, 2019, and required lessees to recognize a liability to make lease payments and a right-of-use asset, initially measured at the present value of lease payments, for both operating and finance leases. For leases with a term of 12 months or less, lessees were permitted to make an accounting policy election by class of underlying asset to not recognize lease liabilities and lease assets. The guidance allowed lessors and lessees to make an accounting policy election, by class of underlying asset, to not separate non-lease components from lease components. The guidance also provided an optional transition method which allowed entities to initially apply the new guidance in the period of adoption, recognizing a cumulative-effect adjustment to the opening balance of retained earnings, if necessary. The Company elected to apply the alternative transition method and no cumulative-effect adjustment to the opening balance of retained earnings was deemed necessary to record. The Company adopted the above standard on January 1, 2019 and applied the new guidance as of that date. In addition, the Company has presented all income as a single line item within "rental revenues" in the accompanying Consolidated Statements of Operations and Comprehensive Income for the current and comparative period. Refer to the Reclassifications section of Note 2 for additional detail. The Company elected to use the "package of practical expedients", which allowed the Company to not reassess under the new standard prior conclusions about lease identification, lease classification, and initial direct costs. The Company did not make any adjustments to the opening balance of retained earnings upon adoption of the new standard given the nature of the impacts and other transition practical expedients elected by the Company. The leases section above and Note 7 includes a discussion of the effect of the adoption of the new standard. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326: Measurement of Credit Losses on Financial Instruments which changes the model for the measurement of credit losses on financial instruments. Specifically, the amendments in the ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. In November 2018, the FASB issued 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses , which clarifies that receivables arising from operating leases are not within the scope of this new guidance. The amendments in this ASU will be effective for the Company January 1, 2020. The adoption of this standard will not materially impact the Company's consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement . This new guidance is effective January 1, 2020, with early adoption permitted, and modifies the disclosure requirements on fair value measurements. Public entities will be required to disclose the following: (i) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and (ii) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. In addition, public entities will no longer be required to disclose the following: (i) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, (ii) the policy for timing of transfers between levels and (iii) the valuation processes for Level 3 fair value measurements. The new pronouncement also clarifies and modifies certain existing provisions, including eliminating "at a minimum" from the phrase "an entity shall disclose at a minimum" to promote the appropriate exercise of discretion by entities when considering fair value measurement disclosures and clarifying that materiality is an appropriate consideration when evaluating disclosure requirements. The adoption of this standard will not materially impact the Company's consolidated financial statements.
Use of Estimates, Policy	Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. For example, estimates and assumptions have been made with respect to allocating the purchase price of real estate acquisitions, the useful lives of assets, capitalization of development and leasing costs, provision for income taxes, recoverable amounts of receivables and deferred taxes, provision for loan loss, initial valuations and related amortization periods of deferred costs and intangibles, particularly with respect to acquisitions, impairment of long-lived assets, litigation related accruals and disclosures and fair value of debt. Actual results could differ from these and other estimates.

6.375% series a cumulative redeemable perpetual preferred stock
Redeemable noncontrolling interest
Schedule of distributions paid on common stock	Preferred Stock On February 13, 2013, we issued, in a public offering, 10,000,000 shares of 6.375% Series A Cumulative Redeemable Preferred Stock (the "Pre-Merger Preferred Stock") at a price of $25.00 per share, resulting in net proceeds of $242.0 million after issuance costs. In connection with the BPY Transaction, each share of Pre-Merger Preferred Stock was converted into one share of 6.375% Series A cumulative redeemable preferred stock of BPR (the "Series A Preferred Stock"). The Series A Preferred Stock is recorded net of issuance costs within equity on our Consolidated Balance Sheets, and accrues a quarterly dividend at an annual rate of 6.375% . The dividend is paid in arrears in preference to dividends on our Class A Stock, and reduces net income available to common stockholders, and therefore, earnings per share. Preferred stock dividends were $15.9 million for the years ended December 31, 2019 , December 31, 2018 and December 31, 2017 . The Series A Preferred Stock does not have a stated maturity date but we may redeem the Series A Preferred Stock for $25.00 per share plus all accrued and unpaid dividends. Upon certain circumstances surrounding a change of control, holders of Series A Preferred Stock may elect to convert each share of their Series A Preferred Stock into a number of shares of Class A Stock or Class C Stock, at the option of the holder, equivalent to $25.00 plus accrued and unpaid dividends, but not to exceed a cap of 2.4679 shares of Class A Stock or Class C Stock (subject to certain adjustments related to splits, subdivisions, or combinations). The BPY Transaction did not meet the definition of a change in control per the certificate of designation governing the Series A Preferred Stock. Our Board of Directors declared preferred stock dividends during 2019 and 2018 as follows: Declaration Date Record Date Payment Date Dividend Per Share 2019 November 4 December 13, 2019 January 1, 2020 $ 0.3984 August 1 September 13, 2019 October 1, 2019 0.3984 May 6 June 14, 2019 July 1, 2019 0.3984 February 6 March 15, 2019 April 1, 2019 0.3984 2018 November 1 December 14, 2018 January 1, 2019 $ 0.3984 July 31 September 17, 2018 October 1, 2018 0.3984 May 3 June 15, 2018 July 2, 2018 0.3984 February 7 March 15, 2018 April 2, 2018 0.3984
