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.

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.

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 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.

FAIR VALUE

FAIR VALUE	12 Months Ended

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, 2020, 2019 and 2018. Total Fair Value Quoted Prices in Significant Other Significant Provisions for Impairment Year Ended December 31, 2020 Investments in real estate (1) $ 124,817 $ — $ — $ 124,817 $ 133,671 Year Ended December 31, 2019 Investments in real estate (1) $ 599,721 $ — $ — $ 599,721 $ 223,142 Year Ended December 31, 2018 Investments in real estate (1) $ 62,490 $ — $ — $ 62,490 $ 45,866 _______________________________________________________________________________ (1) Refer to Note 2 for more information regarding impairment. The impairment recorded on the Investments in real estate balance represents a loss incurred at consolidated properties. Refer to Note 5 for information regarding the impairment losses recorded on our Unconsolidated Real Estate Affiliates. Unobservable Quantitative Input Range Year ended December 31, 2020 Discount rates 6.00% to 10.75% Terminal capitalization rates 4.00% to 9.50% Year ended December 31, 2019 Agreed upon purchase price N/A Discount rate 5.50% Terminal capitalization rate 4.00% Year ended December 31, 2018 Discount rates 9.75% to 11.00% Terminal capitalization rates 9.50% to 10.25% Disclosure of Fair Value of Financial Instruments The fair values of our financial instruments approximate their carrying amount in our consolidated financial statements except for debt. Management's estimates of fair value are presented below for our debt as of December 31, 2020 and 2019. December 31, 2020 December 31, 2019 Carrying Estimated Carrying Estimated Fixed-rate debt $ 8,581,538 $ 8,556,275 $ 8,627,332 $ 8,631,704 Variable-rate debt 7,533,048 7,583,107 7,275,562 7,355,744 $ 16,114,586 $ 16,139,382 $ 15,902,894 $ 15,987,448 _______________________________________________________________________________ (1) Includes net $3.2 million of market rate adjustments and $105.9 million of deferred financing costs. (2) Includes net $4.7 million of market rate adjustments and $131.8 million of deferred financing costs. The fair value of our junior subordinated notes approximates their carrying amount as of December 31, 2020 and 2019. 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.

The Unconsolidated Real Estate Affiliates represent our investments in real estate joint ventures that are not consolidated. We hold interests in 24 domestic joint ventures, comprising 58 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 (adjusted for impairment and observable price changes). 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, 2020, the balance of ROU assets was $67.7 million, net and lease liabilities was $69.9 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.

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.

If the Company is unsuccessful in obtaining concessions from these creditors, it is possible that the property securing these loans would be transferred to the lenders. In such circumstances, the carrying value of the property may no longer be recoverable and may trigger an impairment charge. These mortgages are non-recourse and the creditors do not have security claims against the Company aside from the collateral property. As of December 31, 2020 , the Company has accrued $26.8 million of default interest related to these mortgages per contractual debt agreements.

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 $79.7 million at one property as of December 31, 2020, and $81.5 million as of December 31, 2019. 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, 2020, we do not anticipate an inability to perform on our obligations with respect to the Retained Debt.

On July 29, 2020, the Company entered into the First Amendment of its Credit Agreement in order to give effect to certain amendments, including, but not limited to the following: • The lenders agreed to certain covenant relief in respect of the financial covenants through the fiscal quarter ending June 30, 2021 (the "Covenant Relief Period"). The maximum total indebtedness to value ratio financial maintenance covenant was eliminated permanently. The minimum fixed charge coverage ratio was reduced to 1.20x during the Covenant Relief Period and increases to 1.35x thereafter. • The applicable margin for the Term A Loans and the Facility is LIBOR plus 3.00% during the Covenant Relief Period – and thereafter, will be LIBOR plus 3.00% if the total net indebtedness to value ratio is greater than 70%. • The Company agreed to maintain an ongoing liquidity covenant (set at $500 million) which will be tested as of the last day of each month against the amount of unrestricted cash, undrawn available amounts under the Facility and undrawn amounts under the new Brookfield Liquidity Facility. The Company has entered into and maintains a $500 million Brookfield Liquidity Facility (the "Brookfield Liquidity Facility") and prior to the date the Company demonstrates compliance with the financial covenants in effect under the Credit Agreement prior to the First Amendment, any interest and principal payments thereunder must be paid-in-kind. • The Company is required to "match-fund" drawings under the Facility in excess of $1.0 billion using proceeds of either the Brookfield Liquidity Facility or issuances of qualified equity interests. The match-funding requirement is required to be made (i) monthly, whereby any drawing during that month is in excess of the prior highest balance of the revolver (in excess of $1.0 billion), (ii) within 10 business days of a request from the agent if as of any day during a month, the excess draw amount would exceed $10 million and (iii) at any time of request for a revolving loan that the excess would be $100 million or greater (which would be match-funded substantially concurrently with the requested revolving loan draw). • The Company is required to make additional prepayments of the Term A loans with proceeds of certain equity, debt issuances and asset sales. • The Company also agreed to a number of additional restrictions, including restrictions on incurring additional indebtedness, making of certain restricted payments and the use of proceeds under the revolving facility, which apply either through the end of the Covenant Relief Period – and in the case of certain provisions, until the Company demonstrates compliance with the financial covenants in effect under the Credit Agreement prior to the First Amendment. As of December 31, 2020, we are not aware of any instances of non-compliance with such covenants. Though there is potential for a risk of default (See Note 18 for discussion specific to COVID-19), in the event the Company fails to maintain compliance with its financial covenants, the Credit 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, although there is no guarantee that these market-based alternatives would be available. 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, 2020 and December 31, 2019. Letters of Credit and Surety Bonds We had outstanding letters of credit and surety bonds of $50.1 million and $50.0 million as of December 31, 2020 and 2019, 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, 2020.

LEASES

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 - 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, 2020, the balance of operating ROU assets was $392.5 million, net and lease liabilities of $74.9 million for seven ground leases and one office lease in the Consolidated Balance Sheets under Topic 842, and are 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, 2020 is as follows: Year Amount 2021 $ 9,470 2022 9,704 2023 9,968 2024 10,200 2025 10,439 2026 and thereafter 155,012 Total undiscounted lease payments 204,793 Less: Present value adjustment (129,897) Total lease liability $ 74,896 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 $ 78,500 Straight-line rent expense recognized for our consolidated operating leases is as follows: Year Ended December 31, 2020 Year Ended December 31, 2019 Ground leases $ 7,717 $ 2,775 Office leases 7,856 7,856 Straight-line rent expense is included in other property operating costs for ground leases and property management and other costs for the office lease, respectively, in the Consolidated Statements of Operations and Comprehensive Income (Loss). 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, 2020 and 2019 and are included in other property operating costs in the Consolidated Statements of Operations and Comprehensive Income (Loss). The following summarizes additional information related to our operating leases as of December 31, 2020 and December 31, 2019: Year Ended December 31, 2020 Year Ended December 31, 2019 Weighted-average remaining lease term (years) 23.2 23.0 Weighted-average discount rate 7.69% 7.67% Supplemental disclosure for the consolidated statement of cash flows: Cash paid for amounts included in the measurement of lease liabilities $9,263 $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, 2020, we own a controlling interest in and consolidated 63 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 2021 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, 2020 are as follows: Year Amount 2021 $ 1,027,192 2022 941,265 2023 831,193 2024 703,715 2025 576,745 Subsequent 1,859,218 $ 5,939,328 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 All lease-related income is reported as a single line item, rental revenues, in our Consolidated Statements of Operations and Comprehensive Income (Loss). 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 years ended December 31, 2020 and December 31, 2019: Year Ended December 31, 2020 Year Ended December 31, 2019 Minimum rents, billed $ 1,005,643 $ 916,624 Tenant recoveries, billed 393,454 362,840 Lease termination income, billed 8,123 13,235 Overage rent, billed 16,061 25,193 COVID-19 rent abatements granted (62,243) — Total contractual operating lease billings 1,361,038 1,317,892 Adjustment to recognize contractual operating lease billings on a straight-line basis 41,885 8,488 Above and below-market tenant leases, net 15,352 22,037 Less provision for doubtful accounts (62,395) (10,733) Total rental revenues, net $ 1,355,880 $ 1,337,684 During 2020, as a result of the COVID-19 pandemic, a significant portion of the Company’s tenants requested rental assistance, whether in the form of deferral or rent reduction. Lease concessions granted in response to the COVID-19 pandemic are accounted for as a lease modification and are recognized prospectively over the remaining lease term when they become legally enforceable. However, prior to the legal execution of the lease concession, when establishing its general allowance, the Company recognizes the portion of estimated concessions that is deemed attributable to the current period through consideration of weighted average remaining lease terms. In the table above, contractual operating lease billings are reduced by rent abatements executed during the period. Such rent abatements, net of estimated lease concessions previously recognized in the general allowance, are recognized as an increase to straight-line rent receivables. In the table above, such amounts are included in the adjustment to recognize contractual operating lease billings on a straight-line basis. Of the total contractual rental revenues we have billed, 78.4% and 77.6% are fixed lease payments for the year ended December 31, 2020 and December 31, 2019, respectively.

INCOME TAXES

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, 2017 through 2020 and are statutorily open to audit by state taxing authorities for the years ended December 31, 2016 through 2020. In conjunction with the BPY Transaction, certain of BPYU’s subsidiaries made a taxable contribution of 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 at the corporate subsidiary level 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 temporary book to tax basis 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, 2020 primarily due to our ability to recognize the benefit of the increased tax basis through operations or sale of properties. Future fair market value declines related to the contributed assets could require a valuation allowance on all or a portion of the deferred tax asset. The Company continues to evaluate the ability to recognize the benefit through operations, sales of properties, and prudent and feasible tax planning strategies. The (benefit from) provision for income taxes for the years ended December 31, 2020, 2019, and 2018 are as follows: December 31, 2020 December 31, 2019 December 31, 2018 Current $ (5,967) $ 17,568 $ 6,499 Deferred (29,400) (7,885) (600,685) Total $ (35,367) $ 9,683 $ (594,186) Total (benefit from) provision for income taxes computed for continuing operations by applying the Federal corporate tax rate for the years ended December 31, 2020, 2019, and 2018 are as follows: December 31, 2020 December 31, 2019 December 31, 2018 Tax at statutory rate on (losses) earnings from continuing operations before income taxes $ (156,733) $ 93,239 $ 734,235 (Decrease) increase in valuation allowance, net (209) 1,505 117 State income (benefit) taxes, net of federal income tax (3,510) 5,649 2,879 Investment Tax Credits — (1,958) (12,134) Tax at statutory rate on REIT income (losses) not subject to Federal income taxes 156,476 (87,988) (695,546) Tax (benefit) expense from prior period (17,889) 13,514 16,369 Tax benefit from change in state rates and apportionment (13,501) (15,538) — Tax benefit from BPY Transaction — — (638,494) Other permanent differences (1) 1,260 (1,612) (Benefit from) provision for income taxes $ (35,367) $ 9,683 $ (594,186) Realization of a deferred tax benefit is dependent upon generating sufficient taxable income in future periods. The Company has $146.4 million of federal and state loss carryforwards, the majority of which are currently scheduled to expire in subsequent years through 2040. State operating losses of $29.4 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, 2020 December 31, 2019 December 31, 2018 Total deferred tax assets $ 666,458 $ 638,513 $ 630,215 Valuation allowance (10,103) (10,362) (8,857) Net deferred tax assets 656,355 628,151 621,358 Total deferred tax liabilities (1,295) (2,491) (2,083) Net deferred tax assets $ 655,060 $ 625,660 $ 619,275 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, 2020, December 31, 2019 and December 31, 2018 are summarized as follows: December 31, 2020 December 31, 2019 December 31, 2018 Operating loss and other carryforwards (1) $ 56,492 $ 42,187 $ 58,328 Other TRS property, primarily differences in basis of assets and liabilities 607,474 582,970 564,528 Interest deduction carryforwards 1,197 10,865 5,276 Valuation allowance (10,103) (10,362) (8,857) Net deferred tax assets $ 655,060 $ 625,660 $ 619,275 _______________________________________________________________________________ (1) Includes solar and other tax credits of $36.1 million, $29.4 million and $43.5 million as of December 31, 2020, December 31, 2019 and December 31, 2018, respectively.

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, 2020. Shares of Class A Stock outstanding were 64,024,422 and 39,127,335 as of December 31, 2019 and 2020, 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

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2020
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 BPYU, 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 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 - 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.
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.
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 RevenuesManagement 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 (Loss). 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 (Loss) 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.
Property Management and Other and General and Administrative Costs	Notes 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, 2020, 2019 and 2018. 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, 2020, 2019 and 2018, 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 9 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 $1,015.0 million and $715.0 million outstanding under our credit facility as of December 31, 2020 and 2019, respectively.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements 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 Company adopted this standard on January 1, 2020 which did not materially impact its 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 Company adopted this standard on January 1, 2020 which did not materially impact its consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform. This temporary guidance is effective as of March 12, 2020 through December 31, 2022 to ease potential burdens related to the accounting for, or recognizing the effects of, reference rate reform on financial reporting. The guidance provides optional expedients for applying existing GAAP to contract modifications and hedging relationships affected by the move of global capital markets away from interbank offered rates, most notably the London Interbank Offered Rate (LIBOR). The Company has not adopted any of the optional expedients or exceptions as of December 31, 2020, but will continue to evaluate the possible adoption of any such expedients or exceptions during the effective period as circumstances evolve.
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 BPYU (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, 2020, December 31, 2019 and December 31, 2018. 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 2020 and 2019 as follows: Declaration Date Record Date Payment Date Dividend Per Share 2020 November 5 December 15, 2020 January 1, 2021 $ 0.3984 August 5 September 15, 2020 October 1, 2020 0.3984 May 7 June 15, 2020 July 1, 2020 0.3984 February 5 March 15, 2020 April 1, 2020 0.3984 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
