COVID-19 Pandemic

COVID-19 Pandemic	9 Months Ended

Unusual or Infrequent Items, or Both [Abstract]
COVID-19 Pandemic	COVID-19 Pandemic Our business has been adversely affected as a result of the COVID-19 pandemic and the preventive measures taken to curb the spread of the virus. Some of the effects on us include the following: • With the exception of grocery stores and other "essential" businesses, many of our retail tenants closed their stores in March 2020 and began reopening when New York City entered phase two of its state-mandated reopening plan on June 22, 2020. • While our buildings remain open, many of our office tenants are working remotely. • We have closed the Hotel Pennsylvania. In connection with the closure, we accrued $9,246,000 of severance for furloughed Hotel Pennsylvania union employees and recognized a corresponding $3,145,000 income tax benefit for the three and nine months ended September 30, 2020. • We have cancelled trade shows at theMART for the remainder of 2020. • Because certain of our development projects were deemed "non-essential," they were temporarily paused in March 2020 due to New York State executive orders and resumed once New York City entered phase one of its state mandated reopening plan on June 8, 2020. • As of April 30, 2020, we placed 1,803 employees on furlough, which included 1,293 employees of Building Maintenance Services LLC ("BMS"), a wholly owned subsidiary, which provides cleaning, security and engineering services primarily to our New York properties, 414 employees at the Hotel Pennsylvania and 96 corporate staff employees. As of October 31, 2020, 40% of the furloughed employees have returned to work. • Effective April 1, 2020, our executive officers waived portions of their annual base salary for the remainder of 2020. • Effective April 1, 2020, each non-management member of our Board of Trustees agreed to forgo their $75,000 annual cash retainer for the remainder of 2020. While we believe our tenants are required to pay rent under their leases, in limited circumstances, we have agreed to and may continue to agree to rent deferrals and rent abatements for certain of our tenants. We have made a policy election in accordance with the Financial Accounting Standards Board (“FASB”) Staff Q&A which provides relief in accounting for leases during the COVID-19 pandemic, allowing us to continue recognizing rental revenue on a straight-line basis for rent deferrals, with no impact to revenue recognition, and to recognize rent abatements as a reduction to rental revenue in the period granted. See Note 4 - Recently Issued Accounting Literature for additional information. For the quarter ended September 30, 2020, we collected 93% (95% including rent deferrals) of rent due from our tenants, comprised of 95% (97% including rent deferrals) from our office tenants and 82% (85% including rent deferrals) from our retail tenants. Rent deferrals generally require repayment in monthly installments over a period not to exceed twelve months. Based on our assessment of the probability of rent collection of our lease receivables, we have written off $13,873,000 and $50,170,000 of receivables arising from the straight-lining of rents for the three and nine months ended September 30, 2020, respectively, including the JCPenney retail lease at Manhattan Mall and the New York & Company, Inc. office lease at 330 West 34th Street. Both tenants have filed for Chapter 11 bankruptcy. In addition, we have written off $12,364,000 and $21,186,000 of tenant receivables deemed uncollectible for the three and nine months ended September 30, 2020, respectively. These write-offs resulted in a reduction of lease revenues and our share of income from partially owned entities. Prospectively, revenue recognition for these tenants will be based on actual amounts received. See Note 5 - Revenue Recognition and Note 8 - Investments in Partially Owned Entities for additional information.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted. These condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q of the Securities and Exchange Commission (“SEC”) and should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2019, as filed with the SEC. 3. Basis of Presentation - continued We have made estimates and assumptions that affect the reported amounts of assets and liabilities, 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. Actual results could differ from those estimates. The results of operations for the three and nine months ended September 30, 2020 are not necessarily indicative of the operating results for the full year.

Recently Issued Accounting Lite

Recently Issued Accounting Literature	9 Months Ended

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recently Issued Accounting Literature	Recently Issued Accounting Literature In June 2016, the FASB issued an update ("ASU 2016-13") Measurement of Credit Losses on Financial Instruments establishing Accounting Standards Codification ("ASC") Topic 326, Financial Instruments - Credit Losses ("ASC 326"), as amended by subsequent ASUs on the topic. ASU 2016-13 changes how entities account for credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance replaces the current “incurred loss” model with an “expected loss” model that requires consideration of a broader range of information to estimate expected credit losses over the lifetime of the financial asset. ASU 2016-13 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2019. In May 2019, the FASB issued ASU 2019-05 Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief to allow companies to irrevocably elect, upon adoption of ASU 2016-13, the fair value option for financial instruments that were previously recorded at amortized cost and are within the scope of ASC Subtopic 326-20 if the instruments are eligible for the fair value option under ASC Subtopic 825-10, Financial Instruments ("ASC 825-10"). We elected to apply the fair value option on an instrument-by-instrument basis to our loans receivable. We adopted this standard effective January 1, 2020 and recorded a $16,064,000 cumulative-effect adjustment to beginning accumulated deficit to recognize credit losses on loans receivable recorded on our consolidated balance sheets. For the nine months ended September 30, 2020, we recorded $13,369,000 of credit losses on our loans receivable which are included in "interest and other investment income (loss), net" on our consolidated statements of income. In March 2020, the FASB issued an update ("ASU 2020-04") establishing ASC Topic 848, Reference Rate Reform . ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. During the nine months ended September 30, 2020, we elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. We continue to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur. In April 2020, the FASB issued a Staff Q&A on accounting for leases during the COVID-19 pandemic, focused on the application of lease guidance in ASC Topic 842, Leases ("ASC 842"). The Q&A states that it would be acceptable to make a policy election regarding rent concessions resulting from COVID-19, which would not require entities to account for these rent concessions as lease modifications when total cash flows resulting from the modified contract are “substantially the same or less” than the cash flows in the original contract. During the three and nine months ended September 30, 2020, in limited circumstances, we granted rent deferrals and rent abatements for certain of our tenants. We have made a policy election in accordance with the Staff Q&A for our portfolio allowing us to not account for the concessions as lease modifications. Accordingly, rent abatements are recognized as reductions to “rental revenues” during the period in which they were granted. Rent deferrals result in an increase to "tenant and other receivables" during the deferral period with no impact on rental revenue recognition. For any concessions that do not meet the guidance contained in the Q&A, the modification guidance in accordance with ASC 842 will be applied. See Note 2 - COVID-19 Pandemic for further details. In August 2020, the FASB issued an update ("ASU 2020-06") Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). ASU 2020-06 simplifies the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock, removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and also simplifies the diluted earnings per share calculation in certain areas. ASU 2020-06 is effective for reporting periods beginning after December 15, 2021, with early adoption permitted. We are currently evaluating the impact of the adoption of ASU 2020-06 on our consolidated financial statements, but do not believe the adoption of this standard will have a material impact on our consolidated financial statements.

Real Estate Fund Investments	Real Estate Fund Investments We are the general partner and investment manager of Vornado Capital Partners Real Estate Fund (the “Fund”) and own a 25.0% interest in the Fund, which had an initial eight-year term ending February 2019. On January 29, 2018, the Fund's term was extended to February 2023. The Fund's three-year investment period ended in July 2013. The Fund is accounted for under ASC Topic 946, Financial Services – Investment Companies (“ASC 946”) and its investments are reported on its balance sheet at fair value, with changes in value each period recognized in earnings. We consolidate the accounts of the Fund into our consolidated financial statements, retaining the fair value basis of accounting. We are the general partner and investment manager of the Crowne Plaza Times Square Hotel Joint Venture (the “Crowne Plaza Joint Venture”) and own a 57.1% interest in the joint venture which owns the 24.7% interest in the Crowne Plaza Times Square Hotel not owned by the Fund. The Crowne Plaza Joint Venture is also accounted for under ASC 946 and we consolidate the accounts of the joint venture into our consolidated financial statements, retaining the fair value basis of accounting. On June 9, 2020, the joint venture between the Fund and the Crowne Plaza Joint Venture defaulted on the $274,355,000 non-recourse loan on the Crowne Plaza Times Square Hotel. The interest-only loan, which bears interest at a floating rate of LIBOR plus 3.69% (3.90% as of September 30, 2020) and provides for additional default interest of 3.00%, was scheduled to mature on July 9, 2020. We are in negotiations with the lenders and there can be no assurance as to the timing and ultimate resolution of these negotiations. As of September 30, 2020, we had four real estate fund investments through the Fund and the Crowne Plaza Joint Venture with an aggregate fair value of $3,739,000, $338,327,000 below cost, and had remaining unfunded commitments of $28,692,000, of which our share was $9,140,000.

Equity Method Investments and Joint Ventures [Abstract]
Investments in Partially Owned Entities	Investments in Partially Owned Entities Fifth Avenue and Times Square JV As of September 30, 2020, we own a 51.5% common interest in a joint venture ("Fifth Avenue and Times Square JV") which owns interests in properties located at 640 Fifth Avenue, 655 Fifth Avenue, 666 Fifth Avenue, 689 Fifth Avenue, 697-703 Fifth Avenue, 1535 Broadway and 1540 Broadway (collectively, the "Properties"). The remaining 48.5% common interest in the joint venture is owned by a group of institutional investors (the "Investors"). Our 51.5% common interest in the joint venture represents an effective 51.0% interest in the Properties. The 48.5% common interest in the joint venture owned by the Investors represents an effective 47.2% interest in the Properties. We also own $1.828 billion of preferred equity interests in certain of the properties. All of the preferred equity has an annual coupon of 4.25% for the first five years, increasing to 4.75% for the next five years and thereafter at a formulaic rate. It can be redeemed under certain conditions on a tax deferred basis. Fifth Avenue and Times Square JV was formed in April 2019, when we contributed our interests in the Properties to the joint venture and transferred a 48.5% common interest in the joint venture to the Investors (the “Transaction”). The Transaction valued the Properties at $5.556 billion, resulting in a $2.571 billion net gain, before noncontrolling interests of $11,945,000, including a gain related to the step up in our basis of the retained portion of the assets to fair value. Subsequent to the Transaction, Manhattan street retail suffered negative market conditions and was further stressed by the COVID-19 pandemic. This has resulted in a decrease in cash flows. On June 30, 2020, we estimated that the fair value of our investment in Fifth Avenue and Times Square JV was approximately $2,955,957,000, or $306,326,000 less than the carrying amount, and concluded that the decline in the value of our investment was "other-than-temporary," resulting in the recognition of a non-cash impairment loss of $306,326,000, before noncontrolling interests of $467,000, for the three months ended June 30, 2020. On September 30, 2020, we estimated that the fair value of our investment in Fifth Avenue and Times Square JV was approximately $2,811,374,000, or $107,023,000 less than the carrying amount as of September 30, 2020 (after recognition of the June 30, 2020 impairment loss), and further concluded that the decline in the value of our investment was "other-than-temporary." Our conclusions were based on, among other factors, the significant challenges facing the retail sector and our inability to forecast a recovery over our anticipated holding period. Accordingly, we recognized a non-cash impairment loss of $107,023,000, before noncontrolling interests of $3,822,000, for the three months ended September 30, 2020 and $413,349,000, before noncontrolling interests of $4,289,000, for the nine months ended September 30, 2020. In determining the fair value of our investment, we considered, among other inputs, a discounted cash flow analysis based upon market conditions and expectations of growth. The impairment losses are included in “(loss) income from partially owned entities” on our consolidated statements of income for the three and nine months ended September 30, 2020. We provide various services to Fifth Avenue and Times Square JV in accordance with management, development, leasing and other agreements. We recognized property management fee income, included in "fee and other income" on our consolidated statements of income, of $1,219,000 and $1,104,000 for the three months ended September 30, 2020 and 2019, respectively, and $2,880,000 and $1,934,000 for the nine months ended September 30, 2020 and 2019, respectively. BMS, our wholly-owned subsidiary, supervises cleaning, security and engineering services at certain of the Properties.

Investments in Partially Owned Entities - continued Alexander’s, Inc. (“Alexander’s”) (NYSE: ALX) As of September 30, 2020, we own 1,654,068 Alexander’s common shares, or approximately 32.4% of Alexander’s common equity. We manage, develop and lease Alexander’s properties pursuant to agreements which expire in March of each year and are automatically renewable. As of September 30, 2020, the market value ("fair value" pursuant to ASC Topic 820, Fair Value Measurements ("ASC 820")) of our investment in Alexander’s, based on Alexander’s September 30, 2020 closing share price of $245.22, was $405,611,000, or $321,077,000 in excess of the carrying amount on our consolidated balance sheet. As of September 30, 2020, the carrying amount of our investment in Alexander’s, excluding amounts owed to us, exceeded our share of the equity in the net assets of Alexander’s by approximately $38,511,000. The majority of this basis difference resulted from the excess of our purchase price for the Alexander’s common stock acquired over the book value of Alexander’s net assets. Substantially all of this basis difference was allocated, based on our estimates of the fair values of Alexander’s assets and liabilities, to real estate (land and buildings). We are amortizing the basis difference related to the buildings into earnings as additional depreciation expense over their estimated useful lives. This depreciation is not material to our share of equity in Alexander’s net income. The basis difference related to the land will be recognized upon disposition of our investment. On September 14, 2020, Alexander's amended and extended the $350,000,000 mortgage loan on the retail condominium of 731 Lexington Avenue. Under the terms of the agreement, Alexander's paid down the loan by $50,000,000 to $300,000,000, extended the maturity date to August 2025 and guaranteed the interest payments and certain leasing costs. The principal of the loan is non-recourse to Alexander's. The interest-only loan remains at the same rate, LIBOR plus 1.40% (1.56% as of September 30, 2020). On October 23, 2020, Alexander's completed a $94,000,000 financing of The Alexander, a 312-unit residential building that is part of Alexander's residential and retail complex located in Rego Park, Queens, New York.

Redeemable Noncontrolling Interests	Redeemable Noncontrolling Interests Redeemable Noncontrolling Partnership Units Redeemable noncontrolling partnership units are primarily comprised of Class A Operating Partnership units held by third parties and are recorded at the greater of their carrying amount or redemption value at the end of each reporting period. Changes in the value from period to period are charged to “additional capital” in Vornado’s consolidated statements of changes in equity and to “partners’ capital” on the consolidated balance sheets of the Operating Partnership.

Redeemable noncontrolling partnership units exclude our Series G-1 through G-4 convertible preferred units and Series D-13 cumulative redeemable preferred units, as they are accounted for as liabilities in accordance with ASC Topic 480, Distinguishing Liabilities and Equity , because of their possible settlement by issuing a variable number of Vornado common shares. Accordingly, the fair value of these units is included as a component of “other liabilities” on our consolidated balance sheets and aggregated $49,947,000 and $50,561,000 as of September 30, 2020 and December 31, 2019, respectively. Changes in the value from period to period, if any, are charged to “interest and debt expense” on our consolidated statements of income. Redeemable Noncontrolling Interest in a Consolidated Subsidiary The consolidated joint venture in which we own a 95% interest (the remaining 5% is owned by the Related Companies ("Related")) is developing Farley Office and Retail (the "Project"). During the second quarter of 2020, a historic tax credit investor (the "Tax Credit Investor") funded $92,400,000 of capital contributions. The Tax Credit Investor is projected to have $142,000,000 of net capital contributed after making an estimated $185,000,000 in total contributions and receiving an estimated $43,000,000 in distributions from the joint venture, which includes amounts paid upon the potential exercise of their put option, as discussed below. The arrangement includes a put option whereby the joint venture may be obligated to purchase the Tax Credit Investor’s ownership interest in the Project at a future date. The put price is calculated based on a pre-determined formula. As exercise of the put option is outside of the joint venture’s control, the Tax Credit Investor’s interest, together with the put option, have been recorded to “redeemable noncontrolling interest in a consolidated subsidiary” on our consolidated balance sheet as of September 30, 2020. The redeemable noncontrolling interest is recorded at the greater of the carrying amount or redemption value at the end of each reporting period. Changes in the value from period to period are charged to “additional capital” in Vornado’s consolidated statements of changes in equity and to “partners’ capital” on the consolidated balance sheets of the Operating Partnership.

Variable Interest Entities [Abstract]
Variable Interest Entities (VIEs)	Variable Interest Entities ("VIEs") Unconsolidated VIEs As of September 30, 2020 and December 31, 2019, we have several unconsolidated VIEs. We do not consolidate these entities because we are not the primary beneficiary and the nature of our involvement in the activities of these entities does not give us power over decisions that significantly affect these entities’ economic performance. We account for our investment in these entities under the equity method (see Note 8 – Investments in Partially Owned Entities ). As of September 30, 2020 and December 31, 2019, the net carrying amount of our investments in these entities was $222,924,000 and $217,451,000, respectively, and our maximum exposure to loss in these entities is limited to the carrying amount of our investments. Consolidated VIEs Our most significant consolidated VIEs are the Operating Partnership (for Vornado), the Farley joint venture and certain properties that have non-controlling interests. These entities are VIEs because the non-controlling interests do not have substantive kick-out or participating rights. We consolidate these entities because we control all significant business activities. As of September 30, 2020, the total assets and liabilities of our consolidated VIEs, excluding the Operating Partnership, were $5,254,102,000 and $2,962,558,000, respectively. As of December 31, 2019, the total assets and liabilities of our consolidated VIEs, excluding the Operating Partnership, were $4,923,656,000 and $2,646,623,000, respectively.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements ASC 820 defines fair value and establishes a framework for measuring fair value. The objective of fair value is to determine the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). ASC 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 – quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities; Level 2 – observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 – unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as consider counterparty credit risk in our assessment of fair value. Considerable judgment is necessary to interpret Level 2 and 3 inputs in determining the fair value of our financial and non-financial assets and liabilities. Accordingly, our fair value estimates, which are made at the end of each reporting period, may be different than the amounts that may ultimately be realized upon sale or disposition of these assets. Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis Financial assets and liabilities that are measured at fair value on our consolidated balance sheets consist of (i) marketable securities, (ii) real estate fund investments, (iii) the assets in our deferred compensation plan (for which there is a corresponding liability on our consolidated balance sheets), (iv) loans receivable (for which we have elected the fair value option under ASC 825-10), (v) interest rate swaps and (vi) mandatorily redeemable instruments (Series G-1 through G-4 convertible preferred units and Series D-13 cumulative redeemable preferred units). The tables below aggregate the fair values of these financial assets and liabilities by their levels in the fair value hierarchy.

Fair Value Measurements - continued Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis - continued Real Estate Fund Investments As of September 30, 2020, we had four real estate fund investments with an aggregate fair value of $3,739,000, $338,327,000 below cost. These investments are classified as Level 3. Significant unobservable quantitative inputs used in determining the fair value of each investment include capitalization rates and discount rates. These rates are based on the location, type and nature of each property, current and anticipated market conditions, industry publications and from the experience of our Acquisitions and Capital Markets departments. Significant unobservable quantitative inputs in the table below were utilized in determining the fair value of these real estate fund investments. Range Weighted Average Unobservable Quantitative Input September 30, 2020 December 31, 2019 September 30, 2020 December 31, 2019 Discount rates 7.8% to 15.0% 8.2% to 12.0% 10.0% 9.3% Terminal capitalization rates 5.5% to 10.1% 4.6% to 8.2% 10.1% 5.3% The inputs above are subject to change based on changes in economic and market conditions and/or changes in use or timing of exit. Changes in discount rates and terminal capitalization rates result in increases or decreases in the fair values of these investments. The discount rates encompass, among other things, uncertainties in the valuation models with respect to terminal capitalization rates and the amount and timing of cash flows. Therefore, a change in the fair value of these investments resulting from a change in the terminal capitalization rate may be partially offset by a change in the discount rate. It is not possible for us to predict the effect of future economic or market conditions on our estimated fair values.

We receive quarterly financial reports from a third-party administrator, which are compiled from the quarterly reports provided to them from each limited partnership and investment fund. The quarterly reports provide net asset values on a fair value basis which are audited by independent public accounting firms on an annual basis. The period of time over which these underlying assets are expected to be liquidated is unknown. The third party administrator does not adjust these values in determining our share of the net assets and we do not adjust these values when reported in our consolidated financial statements.

Fair Value Measurements - continued Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis - continued Loans Receivable Loans receivable consist of loan investments in real estate related assets for which we have elected the fair value option under ASC 825-10 as of January 1, 2020. These investments are classified as Level 3. Significant unobservable quantitative inputs used in determining the fair value of each investment include capitalization rates and discount rates. These rates are based on the location, type and nature of each property, current and anticipated market conditions, industry publications and from the experience of our Acquisitions and Capital Markets departments.

We recognize the fair values of all derivatives in "other assets" or "other liabilities" on our consolidated balance sheets. Derivatives that are not hedges are adjusted to fair value through earnings. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative will either be offset against the change in fair value of the hedge asset, liability, or firm commitment through earnings, or recognized in other comprehensive income until the hedged item is recognized in earnings. Reported net income and equity may increase or decrease prospectively, depending on future levels of interest rates and other variables affecting the fair values of derivative instruments and hedged items, but will have no effect on cash flows.

There were no assets measured at fair value on a nonrecurring basis on our consolidated balance sheet as of December 31, 2019. Our estimate of the fair value of our investment in Fifth Avenue and Times Square JV was measured using a discounted cash flow analysis based upon market conditions and expectations of growth and utilized unobservable quantitative inputs, including a capitalization rate of 4.50% and discount rate of 6.25%. See Note 8 - Investments in Partially Owned Entities for details of non-cash impairment losses recognized during the three and nine months ended September 30, 2020.

Estimates of the fair value of these instruments are determined by the standard practice of modeling the contractual cash flows required under the instrument and discounting them back to their present value at the appropriate current risk adjusted interest rate, which is provided by a third-party specialist. For floating rate debt, we use forward rates derived from observable market yield curves to project the expected cash flows we would be required to make under the instrument. The fair value of cash equivalents and borrowings under our unsecured revolving credit facilities and unsecured term loan are classified as Level 1. The fair value of our secured debt and unsecured debt are classified as Level 2. The table below summarizes the carrying amounts and fair value of these financial instruments.

Stock-based Compensation

Stock-based Compensation	9 Months Ended
	Sep. 30, 2020
Share-based Payment Arrangement [Abstract]
Stock-based Compensation	Stock-based Compensation We account for all equity-based compensation in accordance with ASC Topic 718, Compensation - Stock Compensation . Stock-based compensation expense, a component of "general and administrative" expense on our consolidated statements of income, was $6,170,000 and $5,871,000 for the three months ended September 30, 2020 and 2019, respectively, and $39,638,000 and $48,045,000 for the nine months ended September 30, 2020 and 2019, respectively. 2020 Outperformance Plan ("2020 OPP") On March 30, 2020, the Compensation Committee of Vornado's Board of Trustees (the "Committee") approved the 2020 OPP, a multi-year, $35,000,000 performance-based equity compensation plan of which $32,930,000 was granted to senior executives. The fair value of the 2020 OPP granted was $11,686,000, of which $7,583,000 was immediately expensed due to the acceleration of vesting for employees who are retirement eligible (have reached age 65 or age 60 with at least 20 years of service). The remaining $4,103,000 is being amortized into expense over a five-year period from the date of grant using a graded vesting attribution model. Under the 2020 OPP, participants have the opportunity to earn compensation payable in the form of equity awards if Vornado common shares outperform a predetermined total shareholder return (“TSR”) and/or outperform the market with respect to relative total TSR during the three-year performance period (the “Performance Period”) from March 30, 2020 to March 30, 2023 (the “Measurement Date”). Specifically, awards under the 2020 OPP may potentially be earned if Vornado (i) achieves a TSR above a benchmark weighted index (the “Index”) comprised 80% of the SNL US Office REIT Index and 20% of the SNL US Retail Index over the Performance Period (the “Relative Component”), and/or (ii) achieves a TSR greater than 21% over the Performance Period (the “Absolute Component”). The value of awards under the Relative Component and Absolute Component will be calculated separately and will each be subject to an aggregate $35,000,000 maximum award cap for all participants. The two components will be added together to determine the aggregate award size, which shall also be subject to the aggregate $35,000,000 maximum award cap for all participants. In the event awards are earned under the Absolute Component, but Vornado underperforms the Index by more than 200 basis points per annum over the Performance Period (600 basis points over the three years), the amount earned under the Absolute Component will be reduced based on the degree by which the Index exceeds Vornado’s TSR with the maximum payout being 50% under the Absolute Component. In the event awards are earned under the Relative Component, but Vornado fails to achieve a TSR of at least 2% per annum, awards earned under the Relative Component will be reduced on a ratable sliding scale based on Vornado’s absolute TSR performance, with awards earned under the Relative Component being reduced by a maximum of 50% in the event Vornado’s TSR during the Measurement Period is 0% or negative. If the designated performance objectives are achieved, awards earned under the 2020 OPP will vest ratably on the Measurement Date and the first and second anniversary of the Measurement Date. In addition, all of Vornado’s Named Executive Officers (as defined in Vornado’s Proxy Statement filed on Schedule 14A with the Securities and Exchange Commission on April 3, 2020) are required to hold any earned and vested awards for one year following each such vesting date. Dividends on awards granted under the 2020 OPP accrue during the Performance Period and are paid to participants if awards are ultimately earned based on the achievement of the designated performance objectives.

On June 28, 2019, Arcadia Group closed all of its stores in the United States. 608 Fifth Avenue was subject to a land and building lease which was set to expire in 2033. During the second quarter of 2019, we concluded that the carrying amount of the property was not recoverable and recognized a $93,860,000 non-cash impairment loss on our consolidated statements of income, of which $75,220,000 resulted from the impairment of our right-of-use asset. On May 20, 2020, we entered into an agreement with the land and building lessor at 608 Fifth Avenue to surrender the property. Per the terms of the agreement, we were released from our obligations under the lease and assigned all of our right, title and interest in the tenant leases of 608 Fifth Avenue to the land and building lessor. In connection therewith, we removed the lease liability from our consolidated balance sheets which resulted in a $70,260,000 gain recorded on our consolidated statements of income during the nine months ended September 30, 2020.

Commitments and Contingencies	Commitments and Contingencies Insurance For our properties except Farley Office and Retail, we maintain general liability insurance with limits of $300,000,000 per occurrence and per property, of which $235,000,000 includes communicable disease coverage, and all risk property and rental value insurance with limits of $2.0 billion per occurrence, with sub-limits for certain perils such as flood and earthquake. Our California properties have earthquake insurance with coverage of $350,000,000 per occurrence and in the aggregate, subject to a deductible in the amount of 5% of the value of the affected property. We maintain coverage for certified terrorism acts with limits of $6.0 billion per occurrence and in the aggregate (as listed below), $1.2 billion for non-certified acts of terrorism, and $5.0 billion per occurrence and in the aggregate for terrorism involving nuclear, biological, chemical and radiological (“NBCR”) terrorism events, as defined by the Terrorism Risk Insurance Act of 2002, as amended to date and which has been extended through December 2027. Penn Plaza Insurance Company, LLC (“PPIC”), our wholly owned consolidated subsidiary, acts as a re-insurer with respect to a portion of all risk property and rental value insurance and a portion of our earthquake insurance coverage, and as a direct insurer for coverage for acts of terrorism including NBCR acts. Coverage for acts of terrorism (excluding NBCR acts) is fully reinsured by third-party insurance companies and the Federal government with no exposure to PPIC. For NBCR acts, PPIC is responsible for a deductible of $1,430,413 and 20% of the balance of a covered loss and the Federal government is responsible for the remaining portion of a covered loss. We are ultimately responsible for any loss incurred by PPIC. For Farley Office and Retail, we maintain general liability insurance with limits of $100,000,000 per occurrence, and builder’s risk insurance including coverage for existing property and development activities of $2.8 billion per occurrence and in the aggregate. We maintain coverage for certified and non-certified terrorism acts with limits of $1.0 billion per occurrence and in the aggregate . We continue to monitor the state of the insurance market and the scope and costs of coverage for acts of terrorism and other events. However, we cannot anticipate what coverage will be available on commercially reasonable terms in the future. We are responsible for uninsured losses and for deductibles and losses in excess of our insurance coverage, which could be material . Our debt instruments, consisting of mortgage loans secured by our properties, senior unsecured notes and revolving credit agreements contain customary covenants requiring us to maintain insurance. Although we believe that we have adequate insurance coverage for purposes of these agreements, we may not be able to obtain an equivalent amount of coverage at reasonable costs in the future. Further, if lenders insist on greater coverage than we are able to obtain it could adversely affect our ability to finance or refinance our properties and expand our portfolio. Farley Office and Retail The consolidated joint venture in which we own a 95% ownership interest was designated by Empire State Development ("ESD") to develop Farley Office and Retail. The joint venture entered into a development agreement with ESD and a design-build contract with Skanska Moynihan Train Hall Builders. Under the development agreement with ESD, the joint venture is obligated to build the Moynihan Train Hall, with Vornado and Related each guaranteeing the joint venture’s obligations. Under the design-build agreement, Skanska Moynihan Train Hall Builders is obligated to fulfill all of the joint venture’s obligations. The obligations of Skanska Moynihan Train Hall Builders have been bonded by Skanska USA and bear a full guaranty from Skanska AB. In connection with the development of the property, the joint venture took in a historic tax credit investor partner. Under the terms of the historic tax credit arrangement, the joint venture is required to comply with various laws, regulations, and contractual provisions. Non-compliance with applicable requirements could result in projected tax benefits not being realized and, therefore, may require a refund or reduction of the Tax Credit Investor’s capital contributions. As of September 30, 2020, the Tax Credit Investor has made $92,400,000 in capital contributions. Vornado and Related have guaranteed certain of the joint venture’s obligations to the Tax Credit Investor. Other Commitments and Contingencies We are from time to time involved in legal actions arising in the ordinary course of business. In our opinion, after consultation with legal counsel, the outcome of such matters is not currently expected to have a material adverse effect on our financial position, results of operations or cash flows. Each of our properties has been subjected to varying degrees of environmental assessment at various times. The environmental assessments did not reveal any material environmental contamination. However, there can be no assurance that the identification of new areas of contamination, changes in the extent or known scope of contamination, the discovery of additional sites or changes in cleanup requirements would not result in significant costs to us. 21. Commitments and Contingencies - continued Other Commitments and Contingencies - continued In July 2018, we leased 78,000 square feet at 345 Montgomery Street in San Francisco, CA, to a subsidiary of Regus PLC, for an initial term of 15 years. The obligations under the lease were guaranteed by Regus PLC in an amount of up to $90,000,000. The tenant purported to terminate the lease prior to space delivery. We commenced a suit on October 23, 2019 seeking to enforce the lease and the guarantee. On October 9, 2020, the successor to Regus PLC filed for bankruptcy in Luxembourg. In November 2011, we entered into an agreement with the New York City Economic Development Corporation ("EDC") to lease Piers 92 and 94 (the "Piers") for a 49-year term with five 10-year renewal options. The non-recourse lease with a single-purpose entity calls for current annual rent payments of $2,000,000 with fixed rent steps through the initial term. We operate trade shows and special events at the Piers (and sublease to others for the same uses). In February 2019, an inspection revealed that the piles supporting Pier 92 were structurally unsound (an obligation of EDC to maintain) and we were issued an order by EDC to vacate the property. We continued to make the required lease payments through February 2020, with no abatement provided by EDC for the loss of our right to use Pier 92 or reimbursement for lost revenues. Beginning March 2020, as no resolution had been reached with EDC, we have not paid the monthly rents due under the non-recourse lease. As of September 30, 2020, we have a $46,911,000 lease liability and a $34,563,000 right-of-use asset recorded for this lease. Our mortgage loans are non-recourse to us, except for the mortgage loans secured by 640 Fifth Avenue, 7 West 34th Street and 435 Seventh Avenue, which we guaranteed and therefore are part of our tax basis. In certain cases, we have provided guarantees or master leased tenant space. These guarantees and master leases terminate either upon the satisfaction of specified circumstances or repayment of underlying loans. In addition, we have guaranteed the rent and payments in lieu of real estate taxes due to ESD, an entity of New York State, for Farley Office and Retail. As of September 30, 2020, the aggregate dollar amount of these guarantees and master leases is approximately $1,745,000,000. As of September 30, 2020, $14,080,000 of letters of credit were outstanding under one of our unsecured revolving credit facilities. Our unsecured revolving credit facilities contain financial covenants that require us to maintain minimum interest coverage and maximum debt to market capitalization ratios and provide for higher interest rates in the event of a decline in our ratings below Baa3/BBB. Our unsecured revolving credit facilities also contain customary conditions precedent to borrowing, including representations and warranties, and also contain customary events of default that could give rise to accelerated repayment, including such items as failure to pay interest or principal. As investment manager of the Fund we are entitled to an incentive allocation after the limited partners have received a preferred return on their invested capital. The incentive allocation is subject to catch-up and clawback provisions. Accordingly, based on the September 30, 2020 fair value of the Fund assets, at liquidation we would be required to make a $33,900,000 payment to the limited partners representing a clawback of previously paid incentive allocations, which would have no income statement impact as it was previously accrued. As of September 30, 2020, we expect to fund additional capital to certain of our partially owned entities aggregating approximately $11,000,000. As of September 30, 2020, we have construction commitments aggregating approximately $504,000,000.

Segment Reporting [Abstract]
Segment Information	Segment Information We operate in two reportable segments, New York and Other, which is based on how we manage our business. Net operating income ("NOI") at share represents total revenues less operating expenses including our share of partially owned entities. NOI at share - cash basis represents NOI at share adjusted to exclude straight-line rental income and expense, amortization of acquired below and above market leases, net and other non-cash adjustments. We consider NOI at share - cash basis to be the primary non-GAAP financial measure for making decisions and assessing the unlevered performance of our segments as it relates to the total return on assets as opposed to the levered return on equity. As properties are bought and sold based on NOI at share - cash basis, we utilize this measure to make investment decisions as well as to compare the performance of our assets to that of our peers. NOI at share and NOI at share - cash basis should not be considered alternatives to net income or cash flow from operations and may not be comparable to similarly titled measures employed by other companies. NOI at share - cash basis includes rent that has been deferred as a result of the COVID-19 pandemic. Rent deferrals generally require repayment in monthly installments over a period of time not to exceed twelve months. Below is a reconciliation of net income (loss) to NOI at share and NOI at share - cash basis for the three and nine months ended September 30, 2020 and 2019.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Basis of Presentation	The accompanying consolidated financial statements are unaudited and include the accounts of Vornado and the Operating Partnership and their consolidated subsidiaries. All inter-company amounts have been eliminated and all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations and changes in cash flows have been made. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted. These condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q of the Securities and Exchange Commission (“SEC”) and should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2019, as filed with the SEC. 3. Basis of Presentation - continued We have made estimates and assumptions that affect the reported amounts of assets and liabilities, 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. Actual results could differ from those estimates. The results of operations for the three and nine months ended September 30, 2020 are not necessarily indicative of the operating results for the full year.
Recently Issued Accounting Literature	Recently Issued Accounting Literature In June 2016, the FASB issued an update ("ASU 2016-13") Measurement of Credit Losses on Financial Instruments establishing Accounting Standards Codification ("ASC") Topic 326, Financial Instruments - Credit Losses ("ASC 326"), as amended by subsequent ASUs on the topic. ASU 2016-13 changes how entities account for credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance replaces the current “incurred loss” model with an “expected loss” model that requires consideration of a broader range of information to estimate expected credit losses over the lifetime of the financial asset. ASU 2016-13 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2019. In May 2019, the FASB issued ASU 2019-05 Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief to allow companies to irrevocably elect, upon adoption of ASU 2016-13, the fair value option for financial instruments that were previously recorded at amortized cost and are within the scope of ASC Subtopic 326-20 if the instruments are eligible for the fair value option under ASC Subtopic 825-10, Financial Instruments ("ASC 825-10"). We elected to apply the fair value option on an instrument-by-instrument basis to our loans receivable. We adopted this standard effective January 1, 2020 and recorded a $16,064,000 cumulative-effect adjustment to beginning accumulated deficit to recognize credit losses on loans receivable recorded on our consolidated balance sheets. For the nine months ended September 30, 2020, we recorded $13,369,000 of credit losses on our loans receivable which are included in "interest and other investment income (loss), net" on our consolidated statements of income. In March 2020, the FASB issued an update ("ASU 2020-04") establishing ASC Topic 848, Reference Rate Reform . ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. During the nine months ended September 30, 2020, we elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. We continue to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur. In April 2020, the FASB issued a Staff Q&A on accounting for leases during the COVID-19 pandemic, focused on the application of lease guidance in ASC Topic 842, Leases ("ASC 842"). The Q&A states that it would be acceptable to make a policy election regarding rent concessions resulting from COVID-19, which would not require entities to account for these rent concessions as lease modifications when total cash flows resulting from the modified contract are “substantially the same or less” than the cash flows in the original contract. During the three and nine months ended September 30, 2020, in limited circumstances, we granted rent deferrals and rent abatements for certain of our tenants. We have made a policy election in accordance with the Staff Q&A for our portfolio allowing us to not account for the concessions as lease modifications. Accordingly, rent abatements are recognized as reductions to “rental revenues” during the period in which they were granted. Rent deferrals result in an increase to "tenant and other receivables" during the deferral period with no impact on rental revenue recognition. For any concessions that do not meet the guidance contained in the Q&A, the modification guidance in accordance with ASC 842 will be applied. See Note 2 - COVID-19 Pandemic for further details. In August 2020, the FASB issued an update ("ASU 2020-06") Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). ASU 2020-06 simplifies the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock, removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and also simplifies the diluted earnings per share calculation in certain areas. ASU 2020-06 is effective for reporting periods beginning after December 15, 2021, with early adoption permitted. We are currently evaluating the impact of the adoption of ASU 2020-06 on our consolidated financial statements, but do not believe the adoption of this standard will have a material impact on our consolidated financial statements.
Real Estate Fund Investments	The Fund is accounted for under ASC Topic 946, Financial Services – Investment Companies (“ASC 946”) and its investments are reported on its balance sheet at fair value, with changes in value each period recognized in earnings. We consolidate the accounts of the Fund into our consolidated financial statements, retaining the fair value basis of accounting.
Redeemable Noncontrolling Interests	Redeemable noncontrolling partnership units are primarily comprised of Class A Operating Partnership units held by third parties and are recorded at the greater of their carrying amount or redemption value at the end of each reporting period. Changes in the value from period to period are charged to “additional capital” in Vornado’s consolidated statements of changes in equity and to “partners’ capital” on the consolidated balance sheets of the Operating Partnership. Redeemable noncontrolling partnership units exclude our Series G-1 through G-4 convertible preferred units and Series D-13 cumulative redeemable preferred units, as they are accounted for as liabilities in accordance with ASC Topic 480, Distinguishing Liabilities and Equity
Fair Value Measurement	ASC 820 defines fair value and establishes a framework for measuring fair value. The objective of fair value is to determine the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). ASC 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 – quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities; Level 2 – observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 – unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as consider counterparty credit risk in our assessment of fair value. Considerable judgment is necessary to interpret Level 2 and 3 inputs in determining the fair value of our financial and non-financial assets and liabilities. Accordingly, our fair value estimates, which are made at the end of each reporting period, may be different than the amounts that may ultimately be realized upon sale or disposition of these assets.
Stock-based Compensation	We account for all equity-based compensation in accordance with ASC Topic 718, Compensation - Stock Compensation . Stock-based compensation expense, a component of "general and administrative" expense on our consolidated statements of income, was $6,170,000 and $5,871,000 for the three months ended September 30, 2020 and 2019, respectively, and $39,638,000 and $48,045,000 for the nine months ended September 30, 2020 and 2019, respectively.
