Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business	Organization and Business Vornado Realty Trust (“Vornado”) is a fully‑integrated real estate investment trust (“REIT”) and conducts its business through, and substantially all of its interests in properties are held by, Vornado Realty L.P., a Delaware limited partnership (the “Operating Partnership”). Accordingly, Vornado’s cash flow and ability to pay dividends to its shareholders are dependent upon the cash flow of the Operating Partnership and the ability of its direct and indirect subsidiaries to first satisfy their obligations to creditors. Vornado is the sole general partner of, and owned approximately 93.1% of the common limited partnership interest in the Operating Partnership as of December 31, 2019 . All references to the “Company,” “we,” “us” and “our” mean collectively Vornado, the Operating Partnership and those subsidiaries consolidated by Vornado. We currently own all or portions of: New York: • 19.1 million square feet of Manhattan office in 35 properties; • 2.3 million square feet of Manhattan street retail in 70 properties; • 1,991 units in 10 residential properties; • The 1,700 room Hotel Pennsylvania located on Seventh Avenue at 33rd Street in the heart of the Penn District; and • A 32.4% interest in Alexander’s, Inc. (“Alexander’s”) (NYSE: ALX), which owns seven properties in the greater New York metropolitan area, including 731 Lexington Avenue, the 1.3 million square foot Bloomberg, L.P. headquarters building. Other Real Estate and Investments: • The 3.7 million square foot theMART in Chicago; • A 70% controlling interest in 555 California Street, a three -building office complex in San Francisco’s financial district aggregating 1.8 million square feet; • A 25.0% interest in Vornado Capital Partners, our real estate fund. We are the general partner and investment manager of the fund; and • Other real estate and investments.

Accounting Policies [Abstract]
Basis Of Presentation And Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements include the accounts of Vornado and the Operating Partnership and their consolidated subsidiaries. All inter-company amounts have been eliminated. Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), which require us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Certain prior year balances have been reclassified in order to conform to the current period presentation. For the years ended December 31, 2018 and 2017, "property rentals" of $1,760,205,000 and $1,714,952,000 , respectively, and "tenant expense reimbursements" of $247,128,000 and $233,424,000 , respectively, were grouped into "rental revenues" on our consolidated statements of income in accordance with Accounting Standards Codification ("ASC") Topic 205, Presentation of Financial Statements. Recently Issued Accounting Literature In February 2016, the Financial Accounting Standards Board ("FASB") issued an update (“ASU 2016-02”) establishing ASC Topic 842, Leases ("ASC 842"), as amended by subsequent ASUs on the topic, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. ASU 2016-02 requires lessees to apply a two-method approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase. Lessees are required to record a right-of-use ("ROU") asset and a lease liability for all leases with a term of greater than 12 months. Lease liabilities equal the present value of future lease payments. Right-of-use assets equal the lease liabilities adjusted for accrued rent expense, initial direct costs, lease incentives and prepaid lease payments. Leases with a term of 12 months or less will be accounted for similar to the previously existing lease guidance under ASC Topic 840, Leases ("ASC 840"). Lease expense is recognized based on the effective interest method for finance leases or on a straight-line basis for operating leases. The accounting applied by the lessor is largely unchanged from that applied under ASC 840. We adopted this standard effective January 1, 2019. In transitioning to ASC 842, we elected to use the practical expedient package available to us and did not elect to use hindsight. As of January 1, 2019, we had 12 ground leases classified as operating leases, for which we were required to record a right-of-use asset and a lease liability equal to the present value of the future lease payments. We will continue to recognize expense on a straight-line basis for these leases. We recorded an aggregate of $526,866,000 of ROU assets and a corresponding $526,866,000 of lease liabilities as a result of the adoption of this standard (see Note 20 - Leases ). 2 . Basis of Presentation and Significant Accounting Policies - continued Recently Issued Accounting Literature - continued Under ASU 2016-02, initial direct costs for both lessees and lessors would include only those costs that are incremental to the arrangement and would not have been incurred if the lease had not been obtained. As a result, beginning January 1, 2019, we no longer capitalize internal leasing costs and instead expense these costs as incurred, as a component of "general and administrative" expense on our consolidated statements of income. For the years ended December 31, 2018 and 2017, we capitalized $5,538,000 and $5,243,000 , respectively, of internal leasing costs. In June 2016, the FASB issued an update (“ASU 2016-13”) Measurement of Credit Losses on Financial Instruments establishing ASC Topic 326, Financial Instruments - Credit Losses , as amended by subsequent ASUs on the topic. ASU 2016-13 changes how entities will 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. We are currently evaluating the impact of the adoption of ASU 2016-13 on our consolidated financial statements, but do not believe the adoption of this standard will have a material impact on our consolidated financial statements. In August 2018, the FASB issued an update (“ASU 2018-13”) Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement to ASC Topic 820, Fair Value Measurement (“ASC 820”). ASU 2018-13 modifies the disclosure requirements for fair value measurements by removing, modifying, and/or adding certain disclosures. ASU 2018-13 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2019. We elected to early adopt ASU 2018-13 effective January 1, 2019. The adoption of this update did not have a material impact on our consolidated financial statements and disclosures. In October 2018, the FASB issued an update ("ASU 2018-16") Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes to ASC Topic 815, Derivatives and Hedging . ASU 2018-16 expands the list of U.S. benchmark interest rates permitted in the application of hedge accounting by adding the OIS rate based on SOFR as an eligible benchmark interest rate. ASU 2018-16 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2018. We adopted this update effective January 1, 2019. The adoption of this update did not have any impact on our consolidated financial statements. 2 . Basis of Presentation and Significant Accounting Policies - continued Significant Accounting Policies Real Estate: Real estate is carried at cost, net of accumulated depreciation and amortization. Betterments, major renewals and certain costs directly related to the improvement and leasing of real estate are capitalized. Maintenance and repairs are expensed as incurred. For redevelopment of existing operating properties, the net book value of the existing property under redevelopment plus the cost for the construction and improvements incurred in connection with the redevelopment are capitalized to the extent the capitalized costs of the property do not exceed the estimated fair value of the redeveloped property when complete. If the cost of the redeveloped property, including the net book value of the existing property, exceeds the estimated fair value of the redeveloped property, the excess is charged to expense. Depreciation is recognized on a straight-line basis over the estimated useful lives which range from 7 to 40 years. Tenant allowances are amortized on a straight-line basis over the lives of the related leases, which approximate the useful lives of the assets. Additions to real estate include interest and debt expense capitalized during construction of $72,200,000 and $73,166,000 for the years ended December 31, 2019 and 2018 , respectively. Upon the acquisition of real estate, we assess the fair value of acquired assets (including land, buildings and improvements, identified intangibles, such as acquired above and below-market leases, acquired in-place leases and tenant relationships) and acquired liabilities and we allocate the purchase price based on these assessments which are on a relative fair value basis. We assess fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including historical operating results, known trends, and market/economic conditions. We amortize identified intangibles that have finite lives over the period they are expected to contribute directly or indirectly to the future cash flows of the property or business acquired. Our properties, including any related right-of-use assets and intangible assets, are individually reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment exists when the carrying amount of an asset exceeds the aggregate projected future cash flows over the anticipated holding period on an undiscounted basis. An impairment loss is measured based on the excess of the property’s carrying amount over its estimated fair value. Impairment analyses are based on our current plans, intended holding periods and available market information at the time the analyses are prepared. If our estimates of the projected future cash flows, or market conditions change, our evaluation of impairment losses may be different and such differences could be material to our consolidated financial statements. The evaluation of anticipated discounted cash flows is subjective and is based, in part, on estimates and assumptions regarding future occupancy, rental rates, capital requirements, capitalization rates and discount rates that could differ materially from actual results. Plans to hold properties over longer periods decrease the likelihood of recording impairment losses. We recognized impairment losses of $107,221,000 and $12,000,000 for the years ended December 31, 2019 and 2018, respectively. There were no impairment losses in the year ended December 31, 2017. Our 95.0% joint venture (the remaining 5.0% is owned by the Related Companies ("Related")) which is developing the Farley Office and Retail Building has entered into a development agreement with Empire State Development (“ESD”), an entity of New York State, to build the adjacent Moynihan Train Hall, with Vornado and Related each guaranteeing the joint venture's obligations. The joint venture has entered into a design-build contract with Skanska Moynihan Train Hall Builders pursuant to which they will build the Moynihan Train Hall, thereby fulfilling all of the joint venture's obligations to ESD. The obligations of Skanska Moynihan Train Hall Builders have been bonded by Skanska USA and bear a full guaranty from Skanska AB. The development expenditures for the Moynihan Train Hall are estimated to be approximately $1.6 billion , which will be funded by governmental agencies. Pursuant to ASC 842-40-55, the joint venture, which we consolidate on our consolidated balance sheets, is required to recognize all development expenditures for the Moynihan Train Hall. Accordingly, the development expenditures paid for by governmental agencies through December 31, 2019 and 2018 of $914,960,000 and $445,693,000 , respectively, are shown as “Moynihan Train Hall development expenditures” with a corresponding obligation recorded in “Moynihan Train Hall obligation” on our consolidated balance sheets. Upon completion of the development, the "Moynihan Train Hall development expenditures" and the offsetting “Moynihan Train Hall obligation” will be removed from our consolidated balance sheets. Partially Owned Entities: We consolidate entities in which we have a controlling financial interest. In determining whether we have a controlling financial interest in a partially owned entity and the requirement to consolidate the accounts of that entity, we consider (i) whether the entity is a variable interest entity (“VIE”) in which we are the primary beneficiary or (ii) whether the entity is a voting interest entity in which we have a majority of the voting interests of the entity. We are deemed to be the primary beneficiary of a VIE when we have (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses or receive benefits that could potentially be significant to the VIE. We generally do not control a partially owned entity if the approval of all of the partners/members is contractually required with respect to decisions that most significantly impact the performance of the partially owned entity. This includes decisions regarding operating/capital budgets, and the placement of new or additional financing secured by the assets of the venture, among others. We account for investments under the equity method when the requirements for consolidation are not met, and we have significant influence over the operations of the investee. Equity method investments are initially recorded at cost and subsequently adjusted for our share of net income or loss and cash contributions and distributions each period. Investments that do not qualify for consolidation or equity method accounting are accounted for under the cost method. 2 . Basis of Presentation and Significant Accounting Policies - continued Significant Accounting Policies - continued Partially Owned Entities - continued: Investments in partially owned entities are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recorded when there is a decline in the fair value below the carrying value and we conclude such decline is other-than-temporary. An impairment loss is measured based on the excess of the carrying amount of an investment over its estimated fair value. Impairment analyses are based on current plans, intended holding periods and available information at the time the analyses are prepared. In the year ended December 31, 2017 , we recognized non-cash impairment losses on investments in partially owned entities aggregating $44,465,000 . There were no non-cash impairment losses on investments in partially owned entities in the years ended December 31, 2019 and 2018. 220 Central Park South Condominium Units Ready For Sale: We are constructing a residential condominium tower at 220 Central Park South ("220 CPS"). Condominium units are reclassed from "development costs and construction in progress" to "220 Central Park South condominium units ready for sale" upon receipt of the unit's temporary certificate of occupancy. These units are substantially complete and ready for sale. Each unit is carried at the lower of its carrying amount or fair value less costs to sell. We have used the relative sales value method to allocate costs to individual condominium units. GAAP income is recognized when legal title transfers upon closing of the condominium unit sales and is included in "net gains on disposition of wholly owned and partially owned assets" on our consolidated statements of income. As of December 31, 2019 and 2018, none of the 220 CPS condominium units ready for sale had a carrying value that exceeded fair value. Cash and Cash Equivalents: Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less and are carried at cost, which approximates fair value due to their short-term maturities. The majority of our cash and cash equivalents consists of (i) deposits at major commercial banks, which may at times exceed the Federal Deposit Insurance Corporation limit, (ii) United States Treasury Bills, and (iii) Certificate of Deposits placed through an Account Registry Service. Restricted Cash: Restricted cash consists of security deposits, cash restricted for the purposes of facilitating a Section 1031 Like-Kind exchange, cash restricted in connection with our deferred compensation plan and cash escrowed under loan agreements, including for debt service, real estate taxes, property insurance and capital improvements. Deferred Charges: Direct financing costs are deferred and amortized over the terms of the related agreements as a component of interest expense. Direct costs related to successful leasing activities are capitalized and amortized on a straight-line basis over the lives of the related leases. All other deferred charges are amortized on a straight-line basis, which approximates the effective interest rate method, in accordance with the terms of the agreements to which they relate. Income Taxes: Vornado operates in a manner intended to enable it to continue to qualify as a REIT under Sections 856‑860 of the Internal Revenue Code of 1986, as amended. Under those sections, a REIT which distributes at least 90% of its REIT taxable income as a dividend to its shareholders each year and which meets certain other conditions will not be taxed on that portion of its taxable income which is distributed to its shareholders. Vornado distributes to its shareholders 100% of its REIT taxable income and therefore, no provision for Federal income taxes is required. Dividends distributed for the year ended December 31, 2019 , were characterized, for federal income tax purposes, as 62.1% ordinary income and 37.9% long-term capital gain. Dividends distributed for the year ended December 31, 2018, were characterized, for federal income tax purposes, as 91.7% ordinary income and 8.3% long-term capital gain. Dividends distributed for the year ended December 31, 2017, were characterized, for federal income tax purposes, as ordinary income. On December 18, 2019, Vornado's Board of Trustees declared a special dividend of $1.95 per share which was paid on January 15, 2020 to common shareholders of record on December 30, 2019 (the "Record Date"). Class A unitholders of the Operating Partnership as of the Record Date received the same distribution amount per unit on January 15, 2020. Approximately $1.74 per share of the special dividend was a long-term capital gain. The dividend was the result of gains from the transfer of a 45.4% common equity interest in the Fifth Avenue and Times Square JV(see Note 6 - Investments in Partially Owned Entities ), the sale of our 25% interest in 330 Madison Avenue (see Note 6 - Investments in Partially Owned Entities ) and other previously disclosed asset sales, partially offset by a tax deduction resulting from our former investment in Toys "R" Us (see Note 6 - Investments in Partially Owned Entities ). We have elected to treat certain consolidated subsidiaries, and may in the future elect to treat newly formed subsidiaries, as taxable REIT subsidiaries pursuant to an amendment to the Internal Revenue Code that became effective January 1, 2001.

Revenue Recognition	Revenue Recognition Our revenues primarily consist of rental revenues and fee and other income. We operate in two reportable segments: New York and Other, with a significant portion of our revenues included in the New York segment. We have the following revenue sources and revenue recognition policies: • Rental revenues include revenues from the leasing of space at our properties to tenants, lease termination income, revenues from the Hotel Pennsylvania, trade shows and tenant services. ◦ Revenues from the leasing of space at our properties to tenants includes (i) lease components, including fixed and variable lease payments, and nonlease components which include reimbursement of common area maintenance expenses, and (ii) reimbursement of real estate taxes and insurance expenses. As lessor, we have elected to combine the lease and nonlease components of our operating lease agreements and account for the components as a single lease component in accordance with ASC 842. Lease revenues and reimbursement of common area maintenance, real estate taxes and insurance are presented in the following tables as "property rentals." Revenues derived from fixed lease payments are recognized on a straight-line basis over the non-cancelable period of the lease, together with renewal options that are reasonably certain of being exercised. We commence rental revenue recognition when the underlying asset is available for use by the lessee. Revenue derived from the reimbursement of real estate taxes, insurance expenses and common area maintenance expenses are generally recognized in the same period as the related expenses are incurred. ◦ Lease termination income is recognized immediately if a tenant vacates or is recognized on a straight-line basis over the shortened remaining lease term in accordance with ASC 842. ◦ Hotel revenue arising from the operation of Hotel Pennsylvania consists of room revenue, food and beverage revenue, and banquet revenue. Room revenue is recognized when the rooms are made available for the guest, in accordance with ASC 842. ◦ Trade shows revenue arising from the operation of trade shows is primarily booth rentals. This revenue is recognized upon the occurrence of the trade shows when the trade show booths are made available for use by the exhibitors, in accordance with ASC 842. ◦ Tenant services revenue arises from sub-metered electric, elevator, trash removal and other services provided to tenants at their request. This revenue is recognized as the services are transferred in accordance with ASC Topic 606, Revenue from Contracts with Customers ("ASC 606"). • Fee and other income includes management, leasing and other revenue arising from contractual agreements with third parties or with partially owned entities and includes Building Maintenance Services LLC (“BMS”) cleaning, engineering and security services.

Equity Method Investments and Joint Ventures [Abstract]
Investments in Partially Owned Entities	Investments in Partially Owned Entities Fifth Avenue and Times Square JV On April 18, 2019 (the “Closing Date”), we entered into a transaction agreement (the “Transaction Agreement”) with a group of institutional investors (the “Investors”). The Transaction Agreement provides for a series of transactions (collectively, the “Transaction”) pursuant to which (i) prior to the Closing Date, we contributed our 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”) to subsidiaries of a newly formed joint venture (“Fifth Avenue and Times Square JV”) and (ii) on the Closing Date, transferred a 48.5% common interest in Fifth Avenue and Times Square JV to the Investors. The 48.5% common interest in the joint venture represents an effective 47.2% interest in the Properties (of which 45.4% was transferred from Vornado). The Properties include approximately 489,000 square feet of retail space, 327,000 square feet of office space, signage associated with 1535 and 1540 Broadway, the parking garage at 1540 Broadway and the theater at 1535 Broadway. We retained the remaining 51.5% common interest in Fifth Avenue and Times Square JV which represents an effective 51.0% interest in the Properties and an aggregate $1.828 billion of preferred equity interests in certain of the properties. We also provided $500,000,000 of temporary preferred equity on 640 Fifth Avenue until May 23, 2019 when mortgage financing was completed. 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. Net cash proceeds from the Transaction were $1.179 billion , after (i) deductions for the defeasance of a $390,000,000 mortgage loan on 666 Fifth Avenue and the repayment of a $140,000,000 mortgage loan on 655 Fifth Avenue, (ii) proceeds from a $500,000,000 mortgage loan on 640 Fifth Avenue, described below, (iii) approximately $23,000,000 used to purchase noncontrolling investors' interests and (iv) approximately $53,000,000 of transaction costs (including $17,000,000 of costs related to the defeasance of the 666 Fifth Avenue mortgage loan). We continue to manage and lease the Properties. We share control with the Investors over major decisions of the joint venture, including decisions regarding leasing, operating and capital budgets, and refinancings. Accordingly, we no longer hold a controlling financial interest in the Properties which has been transferred to the joint venture. As a result, our investment in Fifth Avenue and Times Square JV is accounted for under the equity method from the date of transfer. The Transaction valued the Properties at $5.556 billion resulting in a financial statement net gain of $2.571 billion , before noncontrolling interest of $11,945,000 , including the related step up in our basis of the retained portion of the assets to fair value. The net gain is included in "net gain on transfer to Fifth Avenue and Times Square JV" on our consolidated statements of income for the year ended December 31, 2019 . The gain for tax purposes was approximately $735,000,000 . 6 . Investments in Partially Owned Entities - continued Fifth Avenue and Times Square JV - continued On May 23, 2019, we received $500,000,000 from the redemption of our temporary preferred equity in 640 Fifth Avenue. The temporary preferred equity was redeemed from the proceeds of a $500,000,000 mortgage financing that was completed on the property. The five-year loan, which is guaranteed by us, is interest-only at LIBOR plus 1.01% . The interest rate was swapped for four years to a fixed rate of 3.07% . Management, Development, Leasing and Other Agreements We provide various services to Fifth Avenue and Times Square JV in accordance with management, development, leasing and other agreements, as described below. We receive an annual fee for managing the Properties equal to 2% of the gross revenues from the Properties. In addition, we are entitled to a development fee of 5% of development costs, plus reimbursement of certain costs, for development projects performed by us. We are entitled to 1.5% of development costs, plus reimbursement of certain costs, as a supervisory fee for development projects not performed by us. We provide leasing services for fees calculated based on a percentage of rents, less any commissions paid to third-party real estate brokers, if applicable. We jointly provide leasing services for the retail space with Crown Acquisitions Inc. ("Crown"), and exclusively provide leasing services for the office space. During the year ended December 31, 2019 , we recognized $3,085,000 of property management fee income which is included in "fee and other income" on our consolidated statements of income. BMS, our wholly-owned subsidiary, supervises cleaning, security and engineering services at certain of the Properties. During the year ended December 31, 2019 , we recognized $3,087,000 of income for these services which is included in "fee and other income" on our consolidated statements of income. We believe, based on comparable fees charged by other real estate companies, that the fees described above are at fair market value. Alexander’s, Inc As of December 31, 2019 , 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 December 31, 2019 and 2018 , Alexander’s owed us an aggregate of $1,426,000 and $708,000 , respectively, pursuant to such agreements. As of December 31, 2019 the market value (“fair value” pursuant to ASC 820) of our investment in Alexander’s, based on Alexander’s December 31, 2019 closing share price of $330.35 , was $546,421,000 , or $447,878,000 in excess of the carrying amount on our consolidated balance sheet. As of December 31, 2019 , the carrying amount of our investment in Alexander’s, excluding amounts owed to us, exceeds our share of the equity in the net assets of Alexander’s by approximately $38,838,000 . 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. Management, Development, Leasing and Other Agreements We receive an annual fee for managing Alexander’s and all of its properties equal to the sum of (i) $2,800,000 , (ii) 2% of the gross revenue from the Rego Park II Shopping Center, (iii) $0.50 per square foot of the tenant-occupied office and retail space at 731 Lexington Avenue, and (iv) $324,000 , escalating at 3% per annum, for managing the common area of 731 Lexington Avenue. In addition, we are entitled to a development fee of 6% of development costs, as defined. We provide Alexander’s with leasing services for a fee of 3% of rent for the first ten years of a lease term, 2% of rent for the eleventh through twentieth year of a lease term and 1% of rent for the twenty-first through thirtieth year of a lease term, subject to the payment of rents by Alexander’s tenants. In the event third-party real estate brokers are used, our fee increases by 1% and we are responsible for the fees to the third-parties. We are also entitled to a commission upon the sale of any of Alexander’s assets equal to 3% of gross proceeds, as defined, for asset sales less than $50,000,000 , and 1% of gross proceeds, as defined, for asset sales of $50,000,000 or more. BMS, our wholly-owned subsidiary, supervises (i) cleaning, engineering and security services at Alexander’s 731 Lexington Avenue property and (ii) security services at Alexander’s Rego Park I, Rego Park II properties and The Alexander apartment tower.

Noncontrolling Interest [Abstract]
Redeemable Noncontrolling Interests / Redeemable Partnership Units	Redeemable Noncontrolling Interests/Redeemable Partnership Units Redeemable noncontrolling interests on Vornado’s consolidated balance sheets and redeemable partnership units on the consolidated balance sheets of the Operating Partnership 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. Class A units may be tendered for redemption to the Operating Partnership for cash; Vornado, at its option, may assume that obligation and pay the holder either cash or Vornado common shares on a one-for-one basis. Because the number of Vornado common shares outstanding at all times equals the number of Class A units owned by Vornado, the redemption value of each Class A unit is equivalent to the market value of one Vornado common share, and the quarterly distribution to a Class A unitholder is equal to the quarterly dividend paid to a Vornado common shareholder.

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 6 – Investments in Partially Owned Entities ). As of December 31, 2019 and 2018 , the net carrying amount of our investments in these entities was $217,451,000 and $257,882,000 , 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 Fund and the Crowne Plaza Joint Venture, 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 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. As of December 31, 2018 , the total assets and liabilities of our consolidated VIEs, excluding the Operating Partnership, were $4,445,436,000 and $2,533,753,000 , respectively.

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. 14 . Fair Value Measurements - continued 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) interest rate swaps and (v) mandatorily redeemable instruments (Series G-1 through G-4 convertible preferred units, 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 as of December 31, 2019 and 2018 , respectively. (Amounts in thousands) As of December 31, 2019 Total Level 1 Level 2 Level 3 Marketable securities $ 33,313 $ 33,313 $ — $ — Real estate fund investments 222,649 — — 222,649 Deferred compensation plan assets ($11,819 included in restricted cash and $91,954 in other assets) 103,773 71,338 — 32,435 Interest rate swaps (included in other assets) 4,327 — 4,327 — Total assets $ 364,062 $ 104,651 $ 4,327 $ 255,084 Mandatorily redeemable instruments (included in other liabilities) $ 50,561 $ 50,561 $ — $ — Interest rate swaps (included in other liabilities) 40,354 — 40,354 — Total liabilities $ 90,915 $ 50,561 $ 40,354 $ — (Amounts in thousands) As of December 31, 2018 Total Level 1 Level 2 Level 3 Marketable securities $ 152,198 $ 152,198 $ — $ — Real estate fund investments 318,758 — — 318,758 Deferred compensation plan assets ($8,402 included in restricted cash and $88,122 in other assets) 96,524 58,716 — 37,808 Interest rate swaps (included in other assets) 27,033 — 27,033 — Total assets $ 594,513 $ 210,914 $ 27,033 $ 356,566 Mandatorily redeemable instruments (included in other liabilities) $ 50,561 $ 50,561 $ — $ — Interest rate swaps (included in other liabilities) 15,236 — 15,236 — Total liabilities $ 65,797 $ 50,561 $ 15,236 $ — Real Estate Fund Investments As of December 31, 2019 , we had four real estate fund investments with an aggregate fair value of $222,649,000 , or $112,915,000 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 as of December 31, 2019 and 2018 . Range Weighted Average Unobservable Quantitative Input December 31, 2019 December 31, 2018 December 31, 2019 December 31, 2018 Discount rates 8.2% to 12.0% 10.0% to 15.0% 9.3% 13.4% Terminal capitalization rates 4.6% to 8.2% 5.4% to 7.7% 5.3% 5.7% 14 . Fair Value Measurements - continued Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis - continued Real Estate Fund Investments - continued The inputs on the previous page 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. The table below summarizes the changes in the fair value of real estate fund investments that are classified as Level 3, for the years ended December 31, 2019 and 2018 . (Amounts in thousands) For the Year Ended December 31, 2019 2018 Beginning balance $ 318,758 $ 354,804 Net unrealized loss on held investments (106,109 ) (83,794 ) Purchases/additional fundings 10,000 68,950 Dispositions — (20,290 ) Net realized loss on exited investments — (912 ) Ending balance $ 222,649 $ 318,758 Deferred Compensation Plan Assets Deferred compensation plan assets that are classified as Level 3 consist of investments in limited partnerships and investment funds, which are managed by third parties. 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. The table below summarizes the changes in the fair value of deferred compensation plan assets that are classified as Level 3, for the years ended December 31, 2019 and 2018 . (Amounts in thousands) For the Year Ended December 31, 2019 2018 Beginning balance $ 37,808 $ 40,128 Sales (27,053 ) (12,621 ) Purchases 18,494 9,183 Realized and unrealized gains (losses) 1,947 (274 ) Other, net 1,239 1,392 Ending balance $ 32,435 $ 37,808 Fair Value Measurements on a Nonrecurring Basis Assets measured at fair value on a nonrecurring basis on our consolidated balance sheets consist primarily of real estate assets required to be measured for impairment at December 31, 2018 . The fair values of real estate assets required to be measured for impairment were determined using comparable sales activity. There were no assets measured at fair value on a nonrecurring basis on our consolidated balance sheets at December 31, 2019 . (Amounts in thousands) As of December 31, 2018 Total Level 1 Level 2 Level 3 Real estate asset $ 14,971 $ — $ — $ 14,971 14 . Fair Value Measurements – continued Financial Assets and Liabilities not Measured at Fair Value Financial assets and liabilities that are not measured at fair value on our consolidated balance sheets include cash equivalents (primarily money market funds, which invest in obligations of the United States government), and our secured and unsecured debt. 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 as of December 31, 2019 and 2018 .

Derivatives and Hedging We utilize various financial instruments to mitigate the impact of interest rate fluctuations on our cash flows and earnings, including hedging strategies, depending on our analysis of the interest rate environment and the costs and risks of such strategies. 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.

Stock-based Compensation

Stock-based Compensation	12 Months Ended
	Dec. 31, 2019
Share-based Payment Arrangement [Abstract]
Stock-based Compensation	Stock-based Compensation On May 16, 2019, our shareholders approved the 2019 Omnibus Share Plan (the “Plan"), which replaces the 2010 Omnibus Share Plan. Under the Plan, the Compensation Committee of Vornado's Board of Trustees (the "Committee") may grant incentive and non-qualified Vornado stock options, restricted stock, restricted Operating Partnership units ("OP units"), out-performance plan awards ("OPPs"), appreciation-only long-term incentive plan units (“AO LTIP Units”) and Performance Conditioned AO LTIP Units to certain of our employees and officers. Awards may be granted up to a maximum 5,500,000 shares, if all awards granted are Full Value awards, as defined in the Plan, and up to 11,000,000 shares, if all of the awards granted are Not Full Value Awards, as defined in the Plan. Full Value Awards are awards of securities, such as restricted shares, that, if all vesting requirements are met, do not require the payment of an exercise price or strike price to acquire the securities. Not Full Value Awards are awards of securities, such as options, that do require the payment of an exercise price or strike price. As of December 31, 2019 , Vornado has approximately 5,207,000 shares available for future grants under the Plan, if all awards granted are Full Value Awards, as defined. We account for all equity-based compensation in accordance with ASC Topic 718, Compensation - Stock Compensation . Below is a summary of our stock-based compensation expense, a component of "general and administrative" expense on our consolidated statements of income. (Amounts in thousands) For the Year Ended December 31, 2019 2018 2017 OP Units $ 39,969 $ 17,763 $ 20,630 Performance Conditioned AO LTIP Units 8,263 — — AO LTIP Units 2,636 2,113 — OPPs 1,944 10,689 10,723 Vornado restricted stock 549 570 729 Vornado stock options 547 587 747 $ 53,908 $ 31,722 $ 32,829 Stock-based compensation expense in the first quarter of 2019 included $16,211,000 from the accelerated vesting of previously issued OP units and Vornado restricted stock due to the removal of the time-based vesting requirement for participants who have reached 65 years of age. The right to sell such awards remains subject to original terms of grant. The increase in expense in the first quarter of 2019 was partially offset by lower stock-based compensation expense of $2,578,000 in each of the second, third and fourth quarter of 2019 and will be completely offset by lower stock-based compensation expense of $8,477,000 thereafter. Stock-based compensation expense for the year ended December 31, 2019 also includes $8,143,000 for OP units granted outside of the Plan to an executive officer in connection with his employment in reliance on the employment inducement exception to shareholder approval provided under the New York Stock Exchange Listing Rule 303A.08; and $2,304,000 for the year ended December 31, 2019 for OP units granted under the Plan to certain executive officers as a result of promotions. The award granted outside of the Plan has a grant date fair value of $25,500,000 and vests 20% on the grant date, 40% on the three-year anniversary of the date of grant, and 40% on the four-year anniversary of the date of grant. The awards granted under the Plan have an aggregate grant date fair value of $15,000,000 and cliff vest after four years. Compensation expense related to OP unit grants are recognized ratably over the vesting period. Additional non-cash expense associated with these awards will be $9,603,000 in each of 2020 and 2021, $7,718,000 in 2022 and $2,655,000 in 2023. Below is a summary of unrecognized compensation expense for the year ended December 31, 2019 . (Amounts in thousands) As of Weighted-Average Remaining Contractual Term OP Units $ 36,390 2.0 AO LTIP Units 2,029 1.5 OPPs 1,783 1.6 Vornado restricted stock 833 1.7 Vornado stock options 832 1.7 Performance Conditioned AO LTIP Units 720 1.6 $ 42,587 1.9 15 . Stock-based Compensation - continued OPPs OPPs are multi-year, performance-based equity compensation plans under which participants have the opportunity to earn a class of units (“OPP units”) of the Operating Partnership if, and only if, Vornado outperforms a predetermined total shareholder return (“TSR”) and/or outperform the market with respect to a relative TSR during the three -year performance period (the “Performance Period”) as described below. OPP units, if earned, become convertible into Class A units of the Operating Partnership (and ultimately into Vornado common shares) following vesting. Awards under the 2018 OPP may be earned if Vornado (i) achieves a TSR level greater than 21% over the Performance Period (the “Absolute Component”) and/or (ii) achieves a TSR above a benchmark weighted index comprised of 70% of the SNL US Office REIT Index and 30% of the SNL US Retail Index over the Performance Period (the “Relative 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 (and potentially fully negated) based on the degree by which the index exceeds Vornado’s TSR. In the event these awards are earned under the Relative Component, but Vornado fails to achieve a TSR of at least 3% 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 applicable measurement period is 0% or negative. If the designated performance objectives are achieved, awards under the 2018 OPP will vest ratably in each of years three, four and five. 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 5, 2019) are required to hold any earned and vested awards for one year following each such vesting date. Dividends on awards granted under the 2018 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. Below is the summary of the OPP units granted during the years December 31, 2018 , 2017 and 2016. Plan Year Total Plan Notional Amount Percentage of Notional Amount Granted Grant Date Fair Value (1) OPP Units Earned 2018 $ 35,000,000 78.2 % $ 10,300,000 To be determined in 2021 2017 35,000,000 86.6 % 10,800,000 Not earned 2016 40,000,000 86.7 % 11,800,000 Not earned ________________________________________ (1) During the years ended December 31, 2018 and 2017, $8,040,000 , and $7,558,000 , respectively, was immediately expensed on the respective grant date due to acceleration of vesting for employees who are retirement eligible (have reached age 65 or age 60 with at least 20 years of service). 15 . Stock-based Compensation - continued Vornado Stock Options Vornado stock options are granted at an exercise price equal to the average of the high and low market price of Vornado’s common shares on the NYSE on the date of grant, generally vest over 4 years and expire 10 years from the date of grant. Compensation expense related to Vornado stock option awards is recognized on a straight-line basis over the vesting period. Below is a summary of Vornado’s stock option activity for the year ended December 31, 2019 .

As of December 31, 2019 2018 2017 Expected volatility 35% 35% 35% Expected life 5.0 years 5.0 years 5.0 years Risk free interest rate 2.50% 2.25% 1.95% Expected dividend yield 2.9% 2.9% 3.0% The weighted average grant date fair value of options granted during the years ended December 31, 2019 , 2018 and 2017 was $16.64 , $18.42 and $25.84 , respectively. Cash received from option exercises for the years ended December 31, 2019 , 2018 and 2017 was $5,495,000 , $5,927,000 and $28,253,000 , respectively. The total intrinsic value of options exercised during the years ended December 31, 2019 , 2018 and 2017 was $18,954,000 , $25,820,000 and $9,178,000 , respectively. 15 . Stock-based Compensation - continued Performance Conditioned AOLTIP Units On January 14, 2019, the Committee approved the issuance of performance conditioned appreciation-only long-term incentive plan units ("Performance Conditioned AO LTIP Units") pursuant to the 2010 Omnibus Share Plan to our named executive officers ("NEOs") in our 2019 proxy statement. Performance Conditioned AO LTIP Units are AO LTIP Units that require the achievement of certain performance conditions by a specified date or they are forfeited. The performance-based condition is met if Vornado common shares trade at or above 110% of the $64.48 grant price per share for any 20 consecutive days on or before the fourth anniversary following the date of grant. If the performance conditions are not met, the awards are forfeited. If the performance conditions are met, once vested, the awards may be converted into Class A Operating Partnership units in the same manner as AO LTIP Units until ten years from the date of grant. Units Weighted-Average Granted 496,762 $ 62.62 Outstanding as of December 31, 2019 496,762 62.62 The fair value of the Performance Conditioned AO LTIP Units on the date of grant was $8,983,000 , of which $7,481,000 was immediately expensed due to the acceleration of vesting for employees who are retirement eligible. The remaining $1,502,000 is being amortized into expense over a four-year period from the date of grant using a graded vesting attribution model. As of December 31, 2019 Expected volatility 35% Expected life 8.0 years Risk free interest rate 2.76% Expected dividend yield 3.1% AO LTIP Units AO LTIP Units are a class of partnership interests in the Operating Partnership that are intended to qualify as “profits interests” for federal income tax purposes and generally only allow the recipient to realize value to the extent the fair market value of a Vornado common share exceeds the threshold level set at the time the AO LTIP Units are granted, subject to any vesting conditions applicable to the award. The threshold level is intended to be equal to 100% of the then fair market value of a Vornado common share on the date of grant. The value of vested AO LTIP Units is realized through conversion of the AO LTIP Units into Class A Operating Partnership units. The number of Class A Units into which vested AO LTIP Units may be converted is determined based on the quotient of (i) the excess of the conversion value on the conversion date over the threshold value designated at the time the AO LTIP Unit was granted, divided by (ii) the conversion value on the conversion date. The “conversion value” is the value of a Vornado common share on the conversion date multiplied by the Conversion Factor as defined in the Partnership Agreement, which is currently one. AO LTIP Units have a term of 10 years from the grant date. Each holder will generally receive special income allocations in respect of an AO LTIP Unit equal to 10% (or such other percentage specified in the applicable award agreement) of the income allocated in respect of a Class A Unit. Upon conversion of AO LTIP Units to Class A Units, holders will be entitled to receive in respect of each such AO LTIP Unit, on a per unit basis, a special distribution equal to 10% (or such other percentage specified in the applicable award agreement) of the distributions received by a holder of an equivalent number of Class A Units during the period from the grant date of the AO LTIP Units through the date of conversion. Below is a summary of AO LTIP Units activity for the year ended December 31, 2019 . Units Weighted-Average Outstanding as of December 31, 2018 183,233 $ 70.34 Granted 207,808 62.66 Vested (46,285 ) 70.31 Cancelled or expired (7,058 ) 67.59 Outstanding as of December 31, 2019 337,698 65.67 15 . Stock-based Compensation - continued AO LTIP Units - continued AO LTIP Units granted during the years ended December 31, 2019 and 2018 had a fair value of $3,429,000 and $3,484,000 , respectively. The fair value of each AO LTIP Units granted is estimated on the date of grant using an option-pricing model with the following weighted-average assumptions for grants in the year ended December 31, 2019 . As of December 31, 2019 2018 Expected volatility 35% 35% Expected life 5.0 years 5.0 years Risk free interest rate 2.50% 2.25% Expected dividend yield 2.9% 2.9% OP Units OP Units are granted at the average of the high and low market price of Vornado’s common shares on the NYSE on the date of grant, vest ratably over four years and are subject to a taxable book-up event, as defined. Compensation expense related to OP Units is recognized ratably over the vesting period using a graded vesting attribution model. Distributions paid on unvested OP Units are charged to “net income attributable to noncontrolling interests in the Operating Partnership” on Vornado’s consolidated statements of income and to “preferred unit distributions” on the Operating Partnership’s consolidated statements of income and amounted to $4,070,000 , $2,559,000 and $2,310,000 in the years ended December 31, 2019 , 2018 and 2017 , respectively. Below is a summary of restricted OP unit activity for the year ended December 31, 2019 . Unvested Units Units Weighted-Average Grant-Date Fair Value Unvested as of December 31, 2018 641,844 $ 72.79 Granted 927,812 63.30 Vested (418,692 ) 66.45 Cancelled or expired (2,651 ) 68.34 Unvested as of December 31, 2019 1,148,313 67.45 OP Units granted in 2019 , 2018 and 2017 had a fair value of $58,732,000 , $17,463,000 and $24,927,000 , respectively. The fair value of OP Units that vested during the years ended December 31, 2019 , 2018 and 2017 was $27,821,000 , $18,037,000 and $20,903,000 , respectively.

(2) Additional Transfer Tax recorded in the first quarter 2018 related to the acquisition of Independence Plaza. The joint venture, in which we have a 50.1% economic interest, that owns Independence Plaza recognized this expense based on the precedent established by the Tax Tribunal's decision regarding One Park Avenue (see Note 4 - Real Estate Fund Investments ). 608 Fifth Avenue During the second quarter of 2019, Arcadia Group US Ltd ("Arcadia Group"), the operator of Topshop, our retail tenant at 608 Fifth Avenue, filed for Chapter 15 bankruptcy protection in the United States. On June 28, 2019, Arcadia Group closed all of its stores in the United States. 608 Fifth Avenue is subject to a land and building lease which expires in 2033. The non-recourse lease calls for fixed lease payments through the term, plus payments for real estate taxes, insurance and operating expenses. Consequently, based on projected future cash flows we concluded that the excess of the carrying amount of the property, which includes our right-of-use asset, over our estimate of fair value was not recoverable resulting in a write down to zero. Our estimate of fair value of the property was derived from a discounted cash flow model using a 7% discount rate and based upon market conditions and expectations of growth. We recognized a $93,860,000 non-cash impairment loss on our consolidated statements of income in the second quarter of 2019, of which $75,220,000 resulted from the impairment of our right-of-use asset. As of December 31, 2019 , a $71,582,000

Leases [Abstract]
Leases	Leases As lessor We lease space to tenants under operating leases. Most of the leases provide for the payment of fixed base rent payable monthly in advance. Office building leases generally require tenants to reimburse us for operating costs and real estate taxes above their base year costs. Certain leases provide for pass-through to tenants for their share of real estate taxes, insurance and common area maintenance. Certain leases also require additional variable rent payments based on a percentage of the tenants’ sales. None of our tenants accounted for more than 10% of total revenues in any of the years ended December 31, 2019 , 2018 and 2017. We have elected to account for lease revenues (including base and variable rent) and the reimbursement of common area maintenance expenses as a single lease component recorded as "rental revenues" on our consolidated statements of income. Under ASC 842, we assess on an individual lease basis whether it is probable that we will collect the future lease payments. We consider the tenant's payment history and current credit status when assessing collectability. When collectability is not deemed probable we write-off the tenant's receivables, including straight-line rent receivables, and limit lease income to cash received. Changes to the collectability of our operating leases are recorded as adjustments to "rental revenues" on our consolidated statements of income, which resulted in a decrease in income of $17,237,000 for the year ended December 31, 2019 . As a result, there is no allowance for doubtful accounts as of December 31, 2019. Prior to the adoption of ASC 842, we maintained an allowance for doubtful accounts for estimated losses on receivables under our lease agreements, including receivables arising from the straight-lining of rent. As of December 31, 2018 and 2017 our allowance for doubtful accounts were as follows: (Amounts in thousands) Description Balance at Beginning of Year Additions Charged Against Operations Uncollectible Accounts Written-off Balance at End of Year Year Ended December 31, 2018 Allowance for doubtful accounts $ 6,480 $ 1,910 $ (2,592 ) $ 5,798 Year Ended December 31, 2017 Allowance for doubtful accounts $ 8,621 $ 26 $ (2,167 ) $ 6,480 As of December 31, 2019 , under ASC 842, future undiscounted cash flows under non-cancelable operating leases were as follows: (Amounts in thousands) As of December 31, 2019 For the year ended December 31, 2020 $ 1,285,867 2021 1,248,659 2022 1,181,887 2023 1,067,014 2024 894,362 Thereafter 4,435,225 As of December 31, 2018, under ASC 840, future undiscounted cash flows under non-cancelable operating leases were as follows: (Amounts in thousands) As of December 31, 2018 For the year ended December 31: 2019 $ 1,547,162 2020 1,510,097 2021 1,465,024 2022 1,407,615 2023 1,269,141 Thereafter 5,832,467 The components of lease revenues for the year ended December 31, 2019 were as follows: (Amounts in thousands) For the Year Ended December 31, 2019 Fixed lease revenues $ 1,513,033 Variable lease revenues 206,677 Lease revenues $ 1,719,710 20 . Leases - continued As lessee We have a number of ground leases which are classified as operating leases. On January 1, 2019, we recorded $526,866,000 of ROU assets and lease liabilities. Our ROU assets were reduced by $37,269,000 of accrued rent expense reclassified from “other liabilities” and $4,267,000 of acquired above-market lease liabilities, net, reclassified from “deferred revenue” and increased by $23,665,000 of acquired below-market lease assets, net, reclassified from “identified intangible assets, net of accumulated amortization” and $1,584,000 of prepaid lease payments reclassified from "other assets." During the second quarter of 2019, we recorded a $75,220,000 impairment loss on our 608 Fifth Avenue ROU Asset (See Note 16 – Transaction Related Costs, Impairment Losses and Other ). As of December 31, 2019 , our ROU assets and lease liabilities were $379,546,000 and $498,254,000 , respectively. The discount rate applied to measure each ROU asset and lease liability is based on our incremental borrowing rate ("IBR"). We consider the general economic environment and our credit rating and factor in various financing and asset specific adjustments to ensure the IBR is appropriate to the intended use of the underlying lease. As we did not elect to apply hindsight, lease term assumptions determined under ASC 840 were carried forward and applied in calculating the lease liabilities recorded under ASC 842. Certain of our ground leases offer renewal options which we assess against relevant economic factors to determine whether we are reasonably certain of exercising or not exercising the option. Lease payments associated with renewal periods that we are reasonably certain will be exercised are included in the measurement of the corresponding lease liability and ROU asset. The following table sets forth information related to the measurement of our lease liabilities as of December 31, 2019 : (Amounts in thousands) As of December 31, 2019 Weighted average remaining lease term (in years) 40.20 Weighted average discount rate 4.84 % Cash paid for operating leases $ 27,817 We recognize rent expense as a component of "operating" expenses on our consolidated statements of income. Rent expense is comprised of fixed and variable lease payments. Variable lease payments include percentage rent and rent resets based on an index or rate.

Fair market rent resets do not give rise to remeasurement of the related right-of-use assets and lease liabilities. Fair market rent resets, which may be material, will be recognized in the periods in which they are incurred. Farley Office and Retail Building The future lease payments detailed previously exclude the ground and building lease at the Farley Office and Retail Building (the "Project"). We have a 95.0% ownership interest in a joint venture with Related which was designated by ESD, an entity of New York State, to develop the Project. The Project will include a new Moynihan Train Hall and approximately 844,000 rentable square feet of commercial space, comprised of approximately 730,000 square feet of office space and approximately 114,000 square feet of retail space. The joint venture has a 99 -year triple-net lease with ESD for the commercial space at the Project. For GAAP purposes the lease has not yet commenced since construction of the Project is ongoing. The lease calls for annual rent payments of $5,000,000 plus fixed payments in lieu of real estate taxes ("PILOT") through June 2030. Following the fixed PILOT payment period, the PILOT is calculated in a manner consistent with buildings subject to New York City real estate taxes and assessments. As of December 31, 2019, future rent and fixed PILOT payments are $556,852,000 . The joint venture has entered into a development agreement with ESD to build the adjacent Moynihan Train Hall, with Vornado and Related each guaranteeing the joint venture's obligations. The joint venture has entered into a design-build contract with Skanska Moynihan Train Hall Builders pursuant to which they will build the Moynihan Train Hall, thereby fulfilling all of the joint venture's obligations to ESD. The obligations of Skanska Moynihan Train Hall Builders have been bonded by Skanska USA and bear a full guaranty from Skanska AB. As a result of our involvement in the construction of the asset, we have been deemed the accounting owner of the property in accordance with ASC 842-40-55.

Multiemployer Plans [Abstract]
Multiemployer Benefit Plans	Multiemployer Benefit Plans Our subsidiaries make contributions to certain multiemployer defined benefit plans (“Multiemployer Pension Plans”) and health plans (“Multiemployer Health Plans”) for our union represented employees, pursuant to the respective collective bargaining agreements. Multiemployer Pension Plans Multiemployer Pension Plans differ from single-employer pension plans in that (i) contributions to multiemployer plans may be used to provide benefits to employees of other participating employers and (ii) if other participating employers fail to make their contributions, each of our participating subsidiaries may be required to bear its then pro rata share of unfunded obligations. If a participating subsidiary withdraws from a plan in which it participates, it may be subject to a withdrawal liability. As of December 31, 2019 , our subsidiaries’ participation in these plans was not significant to our consolidated financial statements. In the years ended December 31, 2019 , 2018 and 2017 , we contributed $10,793,000 , $10,377,000 and $10,113,000 , respectively, towards Multiemployer Pension Plans, which is included as a component of “operating” expenses on our consolidated statements of income. Our subsidiaries’ contributions did not represent more than 5% of total employer contributions in any of these plans for the years ended December 31, 2019 , 2018 and 2017 . Multiemployer Health Plans Multiemployer Health Plans in which our subsidiaries participate provide health benefits to eligible active and retired employees. In the years ended December 31, 2019 , 2018 and 2017 , our subsidiaries contributed $32,407,000 , $30,354,000 and $29,549,000 , respectively, towards these plans, which is included as a component of “operating” expenses on our consolidated statements of income.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Insurance For our properties except the Farley Office and Retail Building, we maintain general liability insurance with limits of $300,000,000 per occurrence and per property, 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 the Farley Office and Retail Building, 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. 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. 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. 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 the 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 the Farley Office and Retail Building. As of December 31, 2019 , the aggregate dollar amount of these guarantees and master leases is approximately $1,524,000,000 . As of December 31, 2019 , $15,880,000 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. 22 . Commitments and Contingencies – continued Other Commitments and Contingencies - continued The joint venture in which we own a 95.0% ownership interest was designated by ESD to develop the Farley Office and Retail Building. The joint venture entered into a development agreement with ESD and a design-build contract with Skanska Moynihan Train Hall Builders.

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.

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. Below is a reconciliation of net income to NOI at share and NOI at share - cash basis for the years ended December 31, 2019 , 2018 and 2017 .

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements include the accounts of Vornado and the Operating Partnership and their consolidated subsidiaries. All inter-company amounts have been eliminated. Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), which require us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
Recently Issued Accounting Literature	Recently Issued Accounting Literature In February 2016, the Financial Accounting Standards Board ("FASB") issued an update (“ASU 2016-02”) establishing ASC Topic 842, Leases ("ASC 842"), as amended by subsequent ASUs on the topic, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. ASU 2016-02 requires lessees to apply a two-method approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase. Lessees are required to record a right-of-use ("ROU") asset and a lease liability for all leases with a term of greater than 12 months. Lease liabilities equal the present value of future lease payments. Right-of-use assets equal the lease liabilities adjusted for accrued rent expense, initial direct costs, lease incentives and prepaid lease payments. Leases with a term of 12 months or less will be accounted for similar to the previously existing lease guidance under ASC Topic 840, Leases ("ASC 840"). Lease expense is recognized based on the effective interest method for finance leases or on a straight-line basis for operating leases. The accounting applied by the lessor is largely unchanged from that applied under ASC 840. We adopted this standard effective January 1, 2019. In transitioning to ASC 842, we elected to use the practical expedient package available to us and did not elect to use hindsight. As of January 1, 2019, we had 12 ground leases classified as operating leases, for which we were required to record a right-of-use asset and a lease liability equal to the present value of the future lease payments. We will continue to recognize expense on a straight-line basis for these leases. We recorded an aggregate of $526,866,000 of ROU assets and a corresponding $526,866,000 of lease liabilities as a result of the adoption of this standard (see Note 20 - Leases ). 2 . Basis of Presentation and Significant Accounting Policies - continued Recently Issued Accounting Literature - continued Under ASU 2016-02, initial direct costs for both lessees and lessors would include only those costs that are incremental to the arrangement and would not have been incurred if the lease had not been obtained. As a result, beginning January 1, 2019, we no longer capitalize internal leasing costs and instead expense these costs as incurred, as a component of "general and administrative" expense on our consolidated statements of income. For the years ended December 31, 2018 and 2017, we capitalized $5,538,000 and $5,243,000 , respectively, of internal leasing costs. In June 2016, the FASB issued an update (“ASU 2016-13”) Measurement of Credit Losses on Financial Instruments establishing ASC Topic 326, Financial Instruments - Credit Losses , as amended by subsequent ASUs on the topic. ASU 2016-13 changes how entities will 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. We are currently evaluating the impact of the adoption of ASU 2016-13 on our consolidated financial statements, but do not believe the adoption of this standard will have a material impact on our consolidated financial statements. In August 2018, the FASB issued an update (“ASU 2018-13”) Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement to ASC Topic 820, Fair Value Measurement (“ASC 820”). ASU 2018-13 modifies the disclosure requirements for fair value measurements by removing, modifying, and/or adding certain disclosures. ASU 2018-13 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2019. We elected to early adopt ASU 2018-13 effective January 1, 2019. The adoption of this update did not have a material impact on our consolidated financial statements and disclosures. In October 2018, the FASB issued an update ("ASU 2018-16") Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes to ASC Topic 815, Derivatives and Hedging . ASU 2018-16 expands the list of U.S. benchmark interest rates permitted in the application of hedge accounting by adding the OIS rate based on SOFR as an eligible benchmark interest rate. ASU 2018-16 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2018. We adopted this update effective January 1, 2019. The adoption of this update did not have any impact on our consolidated financial statements.
Real Estate	Real Estate: Real estate is carried at cost, net of accumulated depreciation and amortization. Betterments, major renewals and certain costs directly related to the improvement and leasing of real estate are capitalized. Maintenance and repairs are expensed as incurred. For redevelopment of existing operating properties, the net book value of the existing property under redevelopment plus the cost for the construction and improvements incurred in connection with the redevelopment are capitalized to the extent the capitalized costs of the property do not exceed the estimated fair value of the redeveloped property when complete. If the cost of the redeveloped property, including the net book value of the existing property, exceeds the estimated fair value of the redeveloped property, the excess is charged to expense. Depreciation is recognized on a straight-line basis over the estimated useful lives which range from 7 to 40 years. Tenant allowances are amortized on a straight-line basis over the lives of the related leases, which approximate the useful lives of the assets. Additions to real estate include interest and debt expense capitalized during construction of $72,200,000 and $73,166,000 for the years ended December 31, 2019 and 2018 , respectively. Upon the acquisition of real estate, we assess the fair value of acquired assets (including land, buildings and improvements, identified intangibles, such as acquired above and below-market leases, acquired in-place leases and tenant relationships) and acquired liabilities and we allocate the purchase price based on these assessments which are on a relative fair value basis. We assess fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including historical operating results, known trends, and market/economic conditions. We amortize identified intangibles that have finite lives over the period they are expected to contribute directly or indirectly to the future cash flows of the property or business acquired. Our properties, including any related right-of-use assets and intangible assets, are individually reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment exists when the carrying amount of an asset exceeds the aggregate projected future cash flows over the anticipated holding period on an undiscounted basis. An impairment loss is measured based on the excess of the property’s carrying amount over its estimated fair value. Impairment analyses are based on our current plans, intended holding periods and available market information at the time the analyses are prepared. If our estimates of the projected future cash flows, or market conditions change, our evaluation of impairment losses may be different and such differences could be material to our consolidated financial statements. The evaluation of anticipated discounted cash flows is subjective and is based, in part, on estimates and assumptions regarding future occupancy, rental rates, capital requirements, capitalization rates and discount rates that could differ materially from actual results. Plans to hold properties over longer periods decrease the likelihood of recording impairment losses. We recognized impairment losses of $107,221,000 and $12,000,000 for the years ended December 31, 2019 and 2018, respectively. There were no impairment losses in the year ended December 31, 2017. Our 95.0% joint venture (the remaining 5.0% is owned by the Related Companies ("Related")) which is developing the Farley Office and Retail Building has entered into a development agreement with Empire State Development (“ESD”), an entity of New York State, to build the adjacent Moynihan Train Hall, with Vornado and Related each guaranteeing the joint venture's obligations. The joint venture has entered into a design-build contract with Skanska Moynihan Train Hall Builders pursuant to which they will build the Moynihan Train Hall, thereby fulfilling all of the joint venture's obligations to ESD. The obligations of Skanska Moynihan Train Hall Builders have been bonded by Skanska USA and bear a full guaranty from Skanska AB. The development expenditures for the Moynihan Train Hall are estimated to be approximately $1.6 billion , which will be funded by governmental agencies. Pursuant to ASC 842-40-55, the joint venture, which we consolidate on our consolidated balance sheets, is required to recognize all development expenditures for the Moynihan Train Hall. Accordingly, the development expenditures paid for by governmental agencies through December 31, 2019 and 2018 of $914,960,000 and $445,693,000 , respectively, are shown as “Moynihan Train Hall development expenditures” with a corresponding obligation recorded in “Moynihan Train Hall obligation” on our consolidated balance sheets. Upon completion of the development, the "Moynihan Train Hall development expenditures" and the offsetting “Moynihan Train Hall obligation” will be removed from our consolidated balance sheets. 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.
Partially Owned Entities	Partially Owned Entities: We consolidate entities in which we have a controlling financial interest. In determining whether we have a controlling financial interest in a partially owned entity and the requirement to consolidate the accounts of that entity, we consider (i) whether the entity is a variable interest entity (“VIE”) in which we are the primary beneficiary or (ii) whether the entity is a voting interest entity in which we have a majority of the voting interests of the entity. We are deemed to be the primary beneficiary of a VIE when we have (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses or receive benefits that could potentially be significant to the VIE. We generally do not control a partially owned entity if the approval of all of the partners/members is contractually required with respect to decisions that most significantly impact the performance of the partially owned entity. This includes decisions regarding operating/capital budgets, and the placement of new or additional financing secured by the assets of the venture, among others. We account for investments under the equity method when the requirements for consolidation are not met, and we have significant influence over the operations of the investee. Equity method investments are initially recorded at cost and subsequently adjusted for our share of net income or loss and cash contributions and distributions each period. Investments that do not qualify for consolidation or equity method accounting are accounted for under the cost method. 2 . Basis of Presentation and Significant Accounting Policies - continued Significant Accounting Policies - continued Partially Owned Entities - continued: Investments in partially owned entities are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recorded when there is a decline in the fair value below the carrying value and we conclude such decline is other-than-temporary. An impairment loss is measured based on the excess of the carrying amount of an investment over its estimated fair value. Impairment analyses are based on current plans, intended holding periods and available information at the time the analyses are prepared.
220 Central Park South Condominium Units Ready For Sale	220 Central Park South Condominium Units Ready For Sale: We are constructing a residential condominium tower at 220 Central Park South ("220 CPS"). Condominium units are reclassed from "development costs and construction in progress" to "220 Central Park South condominium units ready for sale" upon receipt of the unit's temporary certificate of occupancy. These units are substantially complete and ready for sale. Each unit is carried at the lower of its carrying amount or fair value less costs to sell. We have used the relative sales value method to allocate costs to individual condominium units. GAAP income is recognized when legal title transfers upon closing of the condominium unit sales and is included in "net gains on disposition of wholly owned and partially owned assets" on our consolidated statements of income. As of December 31, 2019 and 2018, none of the 220 CPS condominium units ready for sale had a carrying value that exceeded fair value.
Cash And Cash Equivalents	Cash and Cash Equivalents: Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less and are carried at cost, which approximates fair value due to their short-term maturities. The majority of our cash and cash equivalents consists of (i) deposits at major commercial banks, which may at times exceed the Federal Deposit Insurance Corporation limit, (ii) United States Treasury Bills, and (iii) Certificate of Deposits placed through an Account Registry Service.
Restricted Cash	Restricted Cash:
Deferred Charges	Deferred Charges: Direct financing costs are deferred and amortized over the terms of the related agreements as a component of interest expense. Direct costs related to successful leasing activities are capitalized and amortized on a straight-line basis over the lives of the related leases. All other deferred charges are amortized on a straight-line basis, which approximates the effective interest rate method, in accordance with the terms of the agreements to which they relate.
Income Taxes	Income Taxes: Vornado operates in a manner intended to enable it to continue to qualify as a REIT under Sections 856‑860 of the Internal Revenue Code of 1986, as amended. Under those sections, a REIT which distributes at least 90% of its REIT taxable income as a dividend to its shareholders each year and which meets certain other conditions will not be taxed on that portion of its taxable income which is distributed to its shareholders. Vornado distributes to its shareholders 100% of its REIT taxable income and therefore, no provision for Federal income taxes is required. Dividends distributed for the year ended December 31, 2019 , were characterized, for federal income tax purposes, as 62.1% ordinary income and 37.9% long-term capital gain. Dividends distributed for the year ended December 31, 2018, were characterized, for federal income tax purposes, as 91.7% ordinary income and 8.3% long-term capital gain. Dividends distributed for the year ended December 31, 2017, were characterized, for federal income tax purposes, as ordinary income. On December 18, 2019, Vornado's Board of Trustees declared a special dividend of $1.95 per share which was paid on January 15, 2020 to common shareholders of record on December 30, 2019 (the "Record Date"). Class A unitholders of the Operating Partnership as of the Record Date received the same distribution amount per unit on January 15, 2020. Approximately $1.74 per share of the special dividend was a long-term capital gain. The dividend was the result of gains from the transfer of a 45.4% common equity interest in the Fifth Avenue and Times Square JV(see Note 6 - Investments in Partially Owned Entities ), the sale of our 25% interest in 330 Madison Avenue (see Note 6 - Investments in Partially Owned Entities ) and other previously disclosed asset sales, partially offset by a tax deduction resulting from our former investment in Toys "R" Us (see Note 6 - Investments in Partially Owned Entities ). We have elected to treat certain consolidated subsidiaries, and may in the future elect to treat newly formed subsidiaries, as taxable REIT subsidiaries pursuant to an amendment to the Internal Revenue Code that became effective January 1, 2001. Taxable REIT subsidiaries may participate in non-real estate related activities and/or perform non-customary services for tenants and are subject to Federal and State income tax at regular corporate tax rates. Our 220 Central Park South condominium project is held through a taxable REIT subsidiary. 2 . Basis of Presentation and Significant Accounting Policies - continued Significant Accounting Policies - continued At December 31, 2019 and 2018 , our taxable REIT subsidiaries had deferred tax assets, net of valuation allowances, of $57,226,000 and $109,949,000 , respectively, and are included in “other assets” on our consolidated balance sheets. At December 31, 2019 and 2018 , our taxable REIT subsidiaries had deferred tax liabilities of $29,444,000 and $28,676,000 , respectively, which are included in "other liabilities" on our consolidated balance sheets. The deferred tax assets and liabilities relate to net operating loss carry forwards and temporary differences between the book and tax basis of asset and liabilities. During 2019, we utilized $10,257,000 of deferred tax assets related to net operating loss carry forwards associated with our 220 CPS project. For the years ended December 31, 2019, 2018 and 2017, we recognized $103,439,000 , $37,633,000 and $42,375,000 of income tax expense, respectively, based on effective tax rates of approximately 3.0% , 8.2% and 13.3% , respectively. Income tax expense recorded in each of the years primarily relates to our consolidated taxable REIT subsidiaries, and certain state, local, and franchise taxes. The year ended December 31, 2019 included $101,828,000 of income tax expense recognized on the sale of 220 CPS condominium units. The year ended December 31, 2018 included $16,771,000 of income tax expense relating to the purchase price fair value adjustment recorded upon our acquisition of an additional 44.9% ownership interest in Farley Office and Retail Building and $13,888,000 of income tax expense recognized on the sale of 220 CPS units. The Company has no uncertain tax positions recognized as of December 31, 2019 and 2018. The Operating Partnership’s partners are required to report their respective share of taxable income on their individual tax returns.
Revenue Recognition	Rental revenues include revenues from the leasing of space at our properties to tenants, lease termination income, revenues from the Hotel Pennsylvania, trade shows and tenant services. ◦ Revenues from the leasing of space at our properties to tenants includes (i) lease components, including fixed and variable lease payments, and nonlease components which include reimbursement of common area maintenance expenses, and (ii) reimbursement of real estate taxes and insurance expenses. As lessor, we have elected to combine the lease and nonlease components of our operating lease agreements and account for the components as a single lease component in accordance with ASC 842. Lease revenues and reimbursement of common area maintenance, real estate taxes and insurance are presented in the following tables as "property rentals." Revenues derived from fixed lease payments are recognized on a straight-line basis over the non-cancelable period of the lease, together with renewal options that are reasonably certain of being exercised. We commence rental revenue recognition when the underlying asset is available for use by the lessee. Revenue derived from the reimbursement of real estate taxes, insurance expenses and common area maintenance expenses are generally recognized in the same period as the related expenses are incurred. ◦ Lease termination income is recognized immediately if a tenant vacates or is recognized on a straight-line basis over the shortened remaining lease term in accordance with ASC 842. ◦ Hotel revenue arising from the operation of Hotel Pennsylvania consists of room revenue, food and beverage revenue, and banquet revenue. Room revenue is recognized when the rooms are made available for the guest, in accordance with ASC 842. ◦ Trade shows revenue arising from the operation of trade shows is primarily booth rentals. This revenue is recognized upon the occurrence of the trade shows when the trade show booths are made available for use by the exhibitors, in accordance with ASC 842. ◦ Tenant services revenue arises from sub-metered electric, elevator, trash removal and other services provided to tenants at their request. This revenue is recognized as the services are transferred in accordance with ASC Topic 606, Revenue from Contracts with Customers ("ASC 606"). • Fee and other income includes management, leasing and other revenue arising from contractual agreements with third parties or with partially owned entities and includes Building Maintenance Services LLC (“BMS”) cleaning, engineering and security services. This revenue is recognized as the services are transferred in accordance with ASC 606.
Redeemable Noncontrolling Interests	Redeemable noncontrolling interests/redeemable 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 $50,561,000 as of December 31, 2019 and 2018 . Changes in the value from period to period, if any, are charged to “interest and debt expense” on our consolidated statements of income.
Variable Interest Entities	Unconsolidated VIEs As of December 31, 2019 and 2018 Consolidated VIEs Our most significant consolidated VIEs are the Operating Partnership (for Vornado), the Fund and the Crowne Plaza Joint Venture, 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.
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).

Unvested share-based payment awards that contain non-forfeitable rights to dividends, whether paid or unpaid, are accounted for as participating securities. Earnings are allocated to participating securities, which include Vornado restricted stock awards, OP Units and OPPs, based on the two-class method. Other potential dilutive unit equivalents such as Vornado stock options, AO LTIP Units and Performance Conditioned AO LTIP Units are included in the computation of diluted income per unit ("EPU") using the treasury stock method, while the dilutive effect of our Series A convertible preferred units is reflected in diluted EPU by application of the if-converted method.
