	2. Basis of Presentation and Significant Accounting Policies
	Basis of Presentation
	The accompanying consolidated financial statements include the accounts of Vornado and its consolidated subsidiaries, including the Operating Partnership. 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, 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
	In February 2013, the Financial Accounting Standards Board (“FASB”) issued an update (“ASU 2013-02”) to Accounting Standards Codification (“ASC”) Topic 220, Comprehensive Income (“Topic 220”). ASU 2013-02 requires additional disclosures regarding significant reclassifications out of each component of accumulated other comprehensive income, including the effect on the respective line items of net income for amounts that are required to be reclassified into net income in their entirety and cross-references to other disclosures providing additional information for amounts that are not required to be reclassified into net income in their entirety. The adoption of this update as of January 1, 2013, did not have a material impact on our consolidated financial statements, but resulted in additional disclosures (see Note 12 – Shareholders' Equity – Accumulated Other Comprehensive Income (Loss)).
	In June 2013, the FASB issued an update (“ASU 2013-08”) to ASC Topic 946, Financial Services - Investment Companies (“Topic 946”). ASU 2013-08 amends the guidance in Topic 946 for determining whether an entity qualifies as an investment company and requires certain additional disclosures. ASU 2013-08 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2013. The adoption of this update as of January 1, 2014, did not have any impact on our real estate fund and our consolidated financial statements.
	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 redeveloped property, the excess is charged to expense. Depreciation is recognized on a straight-line basis over 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 expense capitalized during construction of $42,303,000 and $16,801,000 for the years ended December 31, 2013 and 2012, 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. 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 record acquired intangible assets (including acquired above-market leases, acquired in-place leases and tenant relationships) and acquired intangible liabilities (including below–market leases) at their estimated fair value separate and apart from goodwill. 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.
	2. Basis of Presentation and Significant Accounting Policies - continued
	Our properties, including any related 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, anticipated holding periods, 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 cash flows is subjective and is based, in part, on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results. Plans to hold properties over longer periods decrease the likelihood of recording impairment losses.
	The table below summarizes impairment losses, acquisition related costs and tenant buy-outs in the years ended December 31, 2013, 2012 and 2011.

	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 factors such as ownership interest, board representation, management representation, authority to make decisions, and contractual and substantive participating rights of the partners/members as well as whether the entity is a variable interest entity (“VIE”) and we are the primary beneficiary. 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 entity is not considered a VIE and the approval of all of the partners/members is contractually required with respect to major decisions, such as operating and capital budgets, the sale, exchange or other disposition of real property, the hiring of a chief executive officer, the commencement, compromise or settlement of any lawsuit, legal proceeding or arbitration or the placement of new or additional financing secured by assets of the venture. 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 on the cost method.
	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 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 years ended December 31, 2013, 2012 and 2011, we recognized non-cash impairment losses on investments in partially owned entities, aggregating $281,098,000, $44,936,000 and $13,794,000, respectively. Included in these amounts are $240,757,000 and $40,000,000 of impairment losses related to our investment in Toys in 2013 and 2012, respectively.
	2. Basis of Presentation and Significant Accounting Policies – continued
	Mortgage and Mezzanine Loans Receivable: We invest in mortgage and mezzanine loans of entities that have significant real estate assets. These investments are either secured by the real property or by pledges of the equity interests of the entities owning the underlying real estate. We record these investments at the stated principal amount net of any unamortized discount or premium. We accrete or amortize any discount or premium over the life of the related receivable utilizing the effective interest method or straight-line method, if the result is not materially different. We evaluate the collectibility of both interest and principal of each of our loans whenever events or changes in circumstances indicate such amounts may not be recoverable. A loan is impaired when it is probable that we will be unable to collect all amounts due according to the existing contractual terms. When a loan is impaired, the amount of the loss accrual is calculated by comparing the carrying amount of the investment to the present value of expected future cash flows discounted at the loan's effective interest rate, or as a practical expedient, to the value of the collateral if the loan is collateral dependent. Interest on impaired loans is recognized when received in cash.
	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 (“CDARS”). To date, we have not experienced any losses on our invested cash.
	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 for debt service, real estate taxes, property insurance and capital improvements.
	Allowance for Doubtful Accounts: We periodically evaluate the collectibility of amounts due from tenants and maintain an allowance for doubtful accounts for estimated losses resulting from the inability of tenants to make required payments under the lease agreements. We also maintain an allowance for receivables arising from the straight-lining of rents. This receivable arises from earnings recognized in excess of amounts currently due under the lease agreements. Management exercises judgment in establishing these allowances and considers payment history and current credit status in developing these estimates. As of December 31, 2013 and 2012, we had $21,869,000 and $37,674,000, respectively, in allowances for doubtful accounts. In addition, as of December 31, 2013 and 2012, we had $4,355,000 and $3,165,000, respectively, in allowances for receivables arising from the straight-lining of rents.
	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.
	2. Basis of Presentation and Significant Accounting Policies – continued
	Revenue Recognition: We have the following revenue sources and revenue recognition policies:
	•       Base Rent — income arising from tenant leases. These rents are recognized over the non-cancelable term of the related leases on a straight-line basis which includes the effects of rent steps and rent abatements under the leases. We commence rental revenue recognition when the tenant takes possession of the leased space and the leased space is substantially ready for its intended use. In addition, in circumstances where we provide a tenant improvement allowance for improvements that are owned by the tenant, we recognize the allowance as a reduction of rental revenue on a straight-line basis over the term of the lease.
	•       Percentage Rent — income arising from retail tenant leases that is contingent upon tenant sales exceeding defined thresholds. These rents are recognized only after the contingency has been removed (i.e., when tenant sales thresholds have been achieved).
	•       Hotel Revenue — income arising from the operation of the Hotel Pennsylvania which consists of rooms revenue, food and beverage revenue, and banquet revenue. Income is recognized when rooms are occupied. Food and beverage and banquet revenue is recognized when the services have been rendered.
	•       Trade Shows Revenue — income arising from the operation of trade shows, including rentals of booths. This revenue is recognized when the trade shows have occurred.
	•       Expense Reimbursements — revenue arising from tenant leases which provide for the recovery of all or a portion of the operating expenses and real estate taxes of the respective property. This revenue is accrued in the same periods as the expenses are incurred.
	•       Management, Leasing and Other Fees — income arising from contractual agreements with third parties or with partially owned entities. This revenue is recognized as the related services are performed under the respective agreements.
	•       Cleveland Medical Mart — revenue arising from the development of the Cleveland Medical Mart. This revenue was recognized as the related services were performed under the respective agreements using the criteria set forth in ASC 605-25, Multiple Element Arrangements

	Derivative Instruments and Hedging Activities: ASC 815, Derivatives and Hedging, as amended, establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. As of December 31, 2013 and 2012, our derivative instruments consisted of an interest rate cap and an interest rate swap. We record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges.
	For derivatives designated as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in earnings. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (loss) (outside of earnings) and subsequently reclassified to earnings when the hedged transaction affects earnings, and the ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. We assess the effectiveness of each hedging relationship by comparing the changes in fair value or cash flows of the derivative hedging instrument with the changes in fair value or cash flows of the designated hedged item or transaction. For derivatives not designated as hedges, changes in fair value are recognized in earnings.
	Income Taxes: We operate in a manner intended to enable us 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. We distribute to shareholders 100% of taxable income and therefore, no provision for Federal income taxes is required. Dividends distributed for the year ended December 31, 2013, were characterized, for federal income tax income tax purposes, as ordinary income. Dividend distributions for the year ended December 31, 2012, were characterized, for Federal income tax purposes, as 62.7% ordinary income and 37.3% long-term capital gain. Dividend distributions for the year ended December 31, 2011 were characterized, for Federal income tax purposes, as 93.2% ordinary income and 6.8% long-term capital gain.
	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 taxable REIT subsidiaries had a combined current income tax expense of approximately $9,608,000, $20,336,000 and $26,645,000 for the years ended December 31, 2013, 2012 and 2011, respectively, and have immaterial differences between the financial reporting and tax basis of assets and liabilities.

	5. Marketable Securities and Derivative Instruments
	Our portfolio of marketable securities is comprised of equity securities that are classified as available-for-sale. Available-for-sale securities are presented on our consolidated balance sheets at fair value. Unrealized gains and losses resulting from the mark-to-market of these securities are included in “other comprehensive income (loss).” Realized gains and losses are recognized in earnings only upon the sale of the securities and are recorded based on the weighted average cost of such securities.
	We evaluate our portfolio of marketable securities for impairment each reporting period. For each of the securities in our portfolio with unrealized losses, we review the underlying cause of the decline in value and the estimated recovery period, as well as the severity and duration of the decline. In our evaluation, we consider our ability and intent to hold these investments for a reasonable period of time sufficient for us to recover our cost basis. We also evaluate the near-term prospects for each of these investments in relation to the severity and duration of the decline.

	Investment in Lexington Realty Trust (“Lexington”) (NYSE: LXP)
	From the inception of our investment in Lexington in 2008, until the first quarter of 2013, we accounted for our investment under the equity method because of our ability to exercise significant influence over Lexington's operating and financial policies. As a result of Lexington's common share issuances, our ownership interest was reduced over time from approximately 17.2% to 8.8% at March 31, 2013. In the first quarter of 2013, we concluded that we no longer have the ability to exercise significant influence over Lexington's operating and financial policies, and began accounting for this investment as a marketable equity security – available for sale, in accordance with ASC Topic 320, Investments – Debt and Equity Securities.
	Investment in J.C. Penney Company, Inc. (“J.C. Penney”) (NYSE: JCP)
	At December 31, 2012, we owned 23,400,000 J.C. Penney common shares comprised of (i) 18,584,010 common shares at a GAAP cost of $19.71 per share, or $366,291,000 in the aggregate, and (ii) 4,815,990 common shares through a forward contract at a weighted average strike price of $29.34 per share, or $141,309,000 in the aggregate.
	On March 4, 2013, we sold 10,000,000 J.C. Penney common shares at a price of $16.03 per share, or $160,300,000 in the aggregate, resulting in a net loss of $36,800,000, which is included in “net gain on disposition of wholly owned and partially owned assets” on our consolidated statements of income. In addition, in the first quarter of 2013, we wrote down the remaining 8,584,010 J.C. Penney common shares we owned to fair value, based on J.C. Penney's March 31, 2013 closing share price of $15.11 per share, and recorded a $39,487,000 impairment loss, which is included in “interest and other investment (loss) income, net” on our consolidated statements of income.
	On September 19, 2013, we settled the forward contract and received 4,815,990 J.C. Penney common shares. In connection therewith, we recognized a $33,487,000 loss from the mark-to-market of the derivative position through its settlement date, which is included in “interest and other investment (loss) income, net” on our consolidated statements of income.
	On September 19, 2013, we also sold the remaining 13,400,000 J.C. Penney common shares in a block trade at a price of $13.00 per share, or $174,200,000 in the aggregate and recognized an $18,114,000 net loss, which is included in “net gain on disposition of wholly owned and partially owned assets” on our consolidated statements of income.

	Toys “R” Us (“Toys”)
	As of December 31, 2013, we own 32.6% of Toys. We account for our investment in Toys under the equity method and record our share of Toys' net income or loss on a one-quarter lag basis because Toys' fiscal year ends on the Saturday nearest January 31, and our fiscal year ends on December 31. The business of Toys is highly seasonal and substantially all of Toys' net income is generated in its fourth quarter.
	At December 31, 2012, we estimated that the fair value of our investment was $40,000,000 less than the carrying amount of $518,041,000 and concluded that the decline in the value of our investment was “other-than-temporary” based on, among other factors, compression of earnings multiples of comparable retailers and our inability to forecast a recovery in the near term. Accordingly, we recognized a non-cash impairment loss of $40,000,000 in the fourth quarter of 2012.
	In the first quarter of 2013, we recognized our share of Toys' fourth quarter net income of $78,542,000 and a corresponding non-cash impairment loss of the same amount to continue to carry over our investment at fair value.
	At December 31, 2013, we estimated that the fair value of our investment in Toys was approximately $80,062,000 ($83,224,000 including $3,162,000 for our share of Toys' accumulated other comprehensive income), or $162,215,000 less than the carrying amount after recognizing our share of Toys third quarter net loss in our fourth quarter. In determining the fair value of our investment, we considered, among other inputs, a December 31, 2013 third-party valuation of Toys. We have concluded that the decline in the value of our investment is “other-than-temporary” based on, among other factors, Toys' 2013 holiday sales results, compression of earnings multiples of comparable retailers and our inability to forecast a recovery in the near term. Accordingly, we recognized an additional non-cash impairment loss of $162,215,000 in the fourth quarter of 2013.
	We will continue to assess the recoverability of our investment each quarter. To the extent the fair value of our investment does not change, we will recognize a non-cash impairment loss equal to our share of Toys' fourth quarter net income, if any, in our first quarter of 2014.
	Below is a summary of Toys' latest available financial information on a purchase accounting basis:

			Net (loss) income attributable to Toys			-396,000			138,000			121,000
		-1		As of December 31, 2013, the carrying amount of our investment in Toys is less than our share of Toys' equity by approximately $322,255,000. This basis difference results primarily from non-cash impairment losses aggregating $280,757,000 that we recognized in 2013 and 2012. We have allocated the basis difference to Toys' real estate (which will be amortized over its estimated useful life), and intangible assets, primarily trade names and trademarks (which is not being amortized and will be recognized upon disposition of our investment).

	Alexander's, Inc. (“Alexander's”) (NYSE: ALX)
	As of December 31, 2013, we own 1,654,068 Alexander's commons shares, or approximately 32.4% of Alexander's common equity. We manage, lease and develop Alexander's properties pursuant to the agreements described below which expire in March of each year and are automatically renewable. As of December 31, 2013, we have a $43,307,000 receivable from Alexander's for fees under these agreements.
	As of December 31, 2013 the market value (“fair value” pursuant to ASC 820) of our investment in Alexander's, based on Alexander's December 31, 2013 closing share price of $330.00, was $545,842,000, or $378,057,000 in excess of the carrying amount on our consolidated balance sheet. As of December 31, 2013, 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 $42,048,000. 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 and Development 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) $272,000, 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.
	Leasing Agreements
	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, or 1% of gross proceeds, as defined, for asset sales of $50,000,000 or more. The total of these amounts is payable to us in annual installments in an amount not to exceed $4,000,000 with interest on the unpaid balance at one-year LIBOR plus 1.0% (1.84% at December 31, 2013).
	Other Agreements
	Building Maintenance Services (“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 and Rego Park II properties, for an annual fee of the costs for such services plus 6%. During the years ended December 31, 2013, 2012 and 2011, we recognized $2,036,000, $2,362,000 and $2,442,000 of income, respectively, under these agreements.

	LNR Property Corporation (“LNR”)
	In January 2013, we and the other equity holders of LNR entered into a definitive agreement to sell LNR for $1.053 billion, of which our share of the net proceeds was $240,474,000. The definitive agreement provided that LNR would not (i) make any cash distributions to the equity holders, including us, through the completion of the sale, which occurred on April 19, 2013, and (ii) take any of the following actions (among others) without the purchaser's approval, the lending or advancing of any money, the acquisition of assets in excess of specified amounts, or the issuance of equity interests. Notwithstanding the terms of the definitive agreement, in accordance with GAAP, we recorded our pro rata share of LNR's earnings on a one-quarter lag basis through the date of sale, which increased the carrying amount of our investment in LNR above our share of the net sales proceeds and resulted in us recognizing an “other-than-temporary” impairment loss on our investment of $27,231,000 in the three months ended March 31, 2013. LNR's net loss for the period from January 1, 2013 through April 19, 2013 was $80,654,000, including a $66,241,000 non-cash impairment loss. Our share of the net loss was $21,131,000, including $17,355,000 for our share of the non-cash impairment loss. In the three months ended June 30, 2013, we recorded our share of the net loss but did not record our share of the non-cash impairment loss, as it was effectively considered in our assessment of “other-than-temporary” impairment loss when we recorded the $27,231,000 impairment loss in the three months ended March 31, 2013. As a result of recording our share of the net loss of $3,776,000 for the three months ended June 30, 2013, the carrying amount of our investment decreased below our share of the net sales proceeds; accordingly, we recorded an offsetting gain on the sale of our investment.

Independence Plaza
On December 21, 2012, we acquired a 58.75% economic interest in Independence Plaza, a three-building 1,328 unit residential complex in the Tribeca submarket of Manhattan (the “Property”). We determined, at that time, that we were the primary beneficiary of the variable interest entity (“VIE”) that owned the Property. Accordingly, we consolidated the operations of the Property from the date of acquisition. Upon consolidation, our preliminary purchase price allocation was primarily to land ($309,848,000) and building ($527,578,000). Based on a third party appraisal and additional information about facts and circumstances that existed at the acquisition date, which was obtained subsequent to the acquisition date, we finalized the purchase price allocation in the first quarter of 2013, and retroactively adjusted our December 31, 2012 consolidated balance sheet as follows:
	(Amounts in thousands)
	Land	$	602,662
	Building and improvements		252,844
	Acquired above-market leases (included in identified intangible assets)		13,115

	Other assets		7,374
	Acquired below-market leases (included in deferred revenue)		-99,074
	Purchase price	$	844,800
On June 7, 2013, the existing $323,000,000 mortgage loan was refinanced with a $550,000,000 five-year fixed-rate interest only mortgage loan bearing interest at 3.48%. The net proceeds of $219,000,000, after repaying the existing loan and closing costs, were distributed to the partners, of which our share was $137,000,000. Simultaneously with the refinancing, we sold an 8.65% economic interest in the Property to our partner for $41,000,000 in cash, which reduced our economic interest to 50.1%. As a result of this transaction, we determined that we were no longer the primary beneficiary of the VIE. Accordingly, we deconsolidated the operations of the Property on June 7, 2013 and began accounting for our investment under the equity method.
650 Madison Avenue
On September 30, 2013, a joint venture, in which we have a 20.1% interest, acquired 650 Madison Avenue, a 27-story, 594,000 square foot Class A office and retail tower located on Madison Avenue between 59th and 60th Street in Manhattan, for $1.295 billion. The property contains 523,000 square feet of office space and 71,000 square feet of retail space. The purchase price was funded with cash and a new $800,000,000 seven-year 4.39% interest-only loan. We account for our investment in the joint venture under the equity method.
The following is a summary of condensed combined financial information for all of our partially owned entities, including Toys, Alexander's and LNR (sold in April 2013), as of December 31, 2013 and 2012 and for the years ended December 31, 2013, 2012 and 2011.

	7. Mortgage and Mezzanine Loans Receivable
	In October 2012, we acquired a 25% participation in a $475,000,000 first mortgage and mezzanine loan for the acquisition and redevelopment of a 10-story retail building at 701 Seventh Avenue in Times Square.  The loan had an interest rate of LIBOR plus 10.2%, with a LIBOR floor of 1.0%.  Of the $475,000,000, we funded $93,750,000, representing our 25% share of the $375,000,000 that was funded at acquisition. In March 2013, we transferred at par, the 25% participation in the mortgage loan. The transfer did not qualify for sale accounting given our continuing interest in the mezzanine loan. Accordingly, we continue to include the 25% participation in the mortgage loan in “Mortgage and Mezzanine Loans Receivable” and have recorded a $59,375,000 liability in “Other Liabilities” on our consolidated balance sheet. On January 14, 2014, the mezzanine loan was repaid.
	On April 17, 2013, a $50,091,000 mezzanine loan that was scheduled to mature in August 2015, was repaid. In connection therewith, we received net proceeds of $55,358,000, including prepayment penalties, which resulted in income of $5,267,000, which is included in “interest and other investment (loss) income” on our consolidated statement of income.
	As of December 31, 2013 and 2012, the carrying amount of mortgage and mezzanine loans receivable was $170,972,000 and $225,359,000, respectively. These loans have a weighted average interest rate of 11.0% and 10.3% at December 31, 2013 and 2012, respectively and have maturities ranging from August 2014 to May 2016.

	Mortgages Payable
	On February 20, 2013, we completed a $390,000,000 financing of the retail condominium located at 666 Fifth Avenue at 53rd Street, which we had acquired December 2012. The 10-year fixed-rate interest only loan bears interest at 3.61%. This property was previously unencumbered. The net proceeds from this financing were approximately $387,000,000.
	On March 25, 2013, we completed a $300,000,000 financing of the Outlets at Bergen Town Center, a 948,000 square foot shopping center located in Paramus, New Jersey. The 10-year fixed-rate interest only loan bears interest at 3.56%. The property was previously encumbered by a $282,312,000 floating-rate loan.
	On May 13, 2013, we notified the lender that due to tenants vacating the Montehiedra Town Center, its operating cash flow will be insufficient to pay the debt service; accordingly, at our request, the mortgage loan was transferred to the special servicer. We are in discussions with the special servicer to restructure the terms of the loan; there can be no assurance as to the timing and ultimate resolution of these discussions.
	On October 30, 2013, we completed the restructuring of the $678,000,000 (face amount) 5.74% Skyline properties mortgage loan. The loan was separated into two tranches; a senior $350,000,000 position and a junior $328,000,000 position. The maturity date has been extended from February 2017 to February 2022, with a one-year extension option. The effective interest rate is 2.965%. Amounts expended to re-lease the property are senior to the $328,000,000 junior position.
	On November 27, 2013, we completed a $450,000,000 refinancing of Eleven Penn Plaza, a 1.1 million square foot Manhattan office building. The seven-year fixed-rate interest only loan bears interest at 3.95%. The net proceeds from this refinancing were approximately $107,000,000 after repaying the existing loan and closing costs.
	Unsecured Revolving Credit Facility
	On March 28, 2013, we extended one of our two $1.25 billion revolving credit facilities from June 2015 to June 2017, with two six-month extension options. The interest on the extended facility was reduced from LIBOR plus 135 basis points to LIBOR plus 115 basis points. In addition, the facility fee was reduced from 30 basis points to 20 basis points.

Redeemable Noncontrolling Interests	'
	11. Redeemable Noncontrolling Interests
	Redeemable noncontrolling interests on our consolidated balance sheets 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 our consolidated statements of changes in equity. Class A units may be tendered for redemption to the Operating Partnership for cash; we, at our 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.
	Below are the details of redeemable noncontrolling interests as of December 31, 2013 and 2012.

These units are redeemable at our option at any time.
	-2	On May 9, 2013, we redeemed all of the outstanding 6.875% Series D-15 Cumulative Redeemable Preferred units with an aggregate face amount of $45,000 for $36,900 in cash, plus accrued and unpaid distributions through the date of redemption.

	Redeemable noncontrolling interests exclude our Series G Convertible Preferred units and Series D-13 Cumulative Redeemable Preferred units, as they are accounted for as liabilities in accordance with ASC 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 $55,097,000 and $55,011,000 as of December 31, 2013 and 2012, respectively.

	12. Shareholders' Equity
	Common Shares
	As of December 31, 2013, there were 187,284,688 common shares outstanding. During 2013, we paid an aggregate of $545,913,000 of common dividends comprised of quarterly common dividends of $0.73 per share.
	Preferred Shares
	On January 25, 2013, we sold 12,000,000 5.40% Series L Cumulative Redeemable Preferred Shares at a price of $25.00 per share in an underwritten public offering pursuant to an effective registration statement. We retained aggregate net proceeds of $290,306,000, after underwriters' discounts and issuance costs and contributed the net proceeds to the Operating Partnership in exchange for 12,000,000 Series L Preferred Units (with economic terms that mirror those of the Series L Preferred Shares). Dividends on the Series L Preferred Shares are cumulative and payable quarterly in arrears. The Series L Preferred Shares are not convertible into, or exchangeable for, any of our properties or securities. On or after five years from the date of issuance (or sooner under limited circumstances), we may redeem the Series L Preferred Shares at a redemption price of $25.00 per share, plus accrued and unpaid dividends through the date of redemption. The Series L Preferred Shares have no maturity date and will remain outstanding indefinitely unless redeemed by us.
	On February 19, 2013, we redeemed all of the outstanding 6.75% Series F Cumulative Redeemable Preferred Shares and 6.75% Series H Cumulative Redeemable Preferred Shares at par, for an aggregate of $262,500,000 in cash, plus accrued and unpaid dividends through the date of redemption.

	Consolidated VIEs
	The entity that owns Independence Plaza was a consolidated VIE at December 31, 2012. On June 7, 2013, we sold a portion of our economic interest in this entity and determined that we are no longer its primary beneficiary. Accordingly, we deconsolidated this VIE (see Note 6 – Investments in Partially Owned Entities). The table below summarizes the assets and liabilities of the VIE at December 31, 2012. The liabilities were secured only by the assets of the VIE, and were non-recourse to us.

	Unconsolidated VIEs
	At December 31, 2013, we have unconsolidated VIEs comprised of our investments in the entities that own the Warner Building and Independence Plaza. 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, 2013, the net carrying amount of our investment in these entities was $152,929,000, and our maximum exposure to loss in these entities, is limited to our investment. At December 31, 2012, we had one unconsolidated VIE, comprised of our investment in the Warner Building which had a carrying amount of $8,775,000.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	14. Fair Value Measurements
	ASC 820, Fair Value Measurement and Disclosures defines fair value and establishes a framework for measuring fair value. The objective of fair value is to determine the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). ASC 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 – quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities; Level 2 – observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 – unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as consider counterparty credit risk in our assessment of fair value. Considerable judgment is necessary to interpret Level 2 and 3 inputs in determining the fair value of our financial and non-financial assets and liabilities. Accordingly, our fair value estimates, which are made at the end of each reporting period, may be different than the amounts that may ultimately be realized upon sale or disposition of these assets.
	Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis
	Financial assets and liabilities that are measured at fair value on our consolidated balance sheets consist of (i) marketable securities, (ii) Real Estate Fund investments, (iii) the assets in our deferred compensation plan (for which there is a corresponding liability on our consolidated balance sheet), (iv) interest rate swaps and (v) mandatorily redeemable instruments (Series G-1 through G-4 convertible preferred units and Series D-13 cumulative redeemable preferred units). The tables below aggregate the fair values of these financial assets and liabilities by their levels in the fair value hierarchy at December 31, 2013 and 2012, respectively.

	Real Estate Fund Investments
	At December 31, 2013, our Real Estate Fund had nine investments with an aggregate fair value of $667,710,000, or $153,413,000 in excess of cost. These investments are classified as Level 3. We use a discounted cash flow valuation technique to estimate the fair value of each of these investments, which is updated quarterly by personnel responsible for the management of each investment and reviewed by senior management at each reporting period. The discounted cash flow valuation technique requires us to estimate cash flows for each investment over the anticipated holding period, which currently ranges from 0.6 to 6.5 years. Cash flows are derived from property rental revenue (base rents plus reimbursements) less operating expenses, real estate taxes and capital and other costs, plus projected sales proceeds in the year of exit. Property rental revenue is based on leases currently in place and our estimates for future leasing activity, which are based on current market rents for similar space plus a projected growth factor. Similarly, estimated operating expenses and real estate taxes are based on amounts incurred in the current period plus a projected growth factor for future periods. Anticipated sales proceeds at the end of an investment's expected holding period are determined based on the net cash flow of the investment in the year of exit, divided by a terminal capitalization rate, less estimated selling costs.
	The fair value of each property is calculated by discounting the future cash flows (including the projected sales proceeds), using an appropriate discount rate and then reduced by the property's outstanding debt, if any, to determine the fair value of the equity in each investment. 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, and current and anticipated market conditions, which are derived from original underwriting assumptions, 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 Fund investments at December 31, 2013.
									Weighted Average
									(based on fair
		Unobservable Quantitative Input					Range		value of investments)
			Discount rates				12.0% to 17.5%		13.90%
			Terminal capitalization rates				5.0% to 6.0%		5.50%
	The above inputs 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 Fund investments that are classified as Level 3, for the years ended December 31, 2013 and 2012.

	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 third-party administrator does not adjust these values in determining our share of the net assets and we do not adjust these values when reported in our consolidated financial statements.

	Fair Value Measurements on a Nonrecurring Basis
Assets measured at fair value on a nonrecurring basis on our consolidated balance sheets consist primarily of our investment in Toys and real estate assets that have been written-down to estimated fair value during 2013 and 2012. See Note 2 – Basis of Presentation and Significant Accounting Policies for details of impairment losses recognized during 2013 and 2012. See Note 6 – Investment in Partially Owned Entities for details of impairment losses related to Toys. The fair values of these assets are determined using widely accepted valuation techniques, including (i) discounted cash flow analysis, which considers, among other things, leasing assumptions, growth rates, discount rates and terminal capitalization rates, (ii) income capitalization approach, which considers prevailing market capitalization rates, and (iii) comparable sales activity. Generally, we consider multiple valuation techniques when measuring fair values but in certain circumstances, a single valuation technique may be appropriate. The tables below aggregate the fair values of these assets by their levels in the fair value hierarchy.

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 U.S. Treasury Bills), mortgage and mezzanine loans receivable 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 is classified as Level 1 and the fair value of our mortgage and mezzanine loans receivable is classified as Level 3. The fair value of our secured and unsecured debt is classified as Level 2. The table below summarizes the carrying amounts and fair value of these financial instruments as of December 31, 2013 and 2012.

Stock-based Compensation	'
	15.       Stock-based Compensation
	Our Omnibus Share Plan (the “Plan”), which was approved in May 2010, provides the Compensation Committee of the Board (the “Committee”) the ability to grant incentive and non-qualified stock options, restricted stock, restricted Operating Partnership units and out-performance plan awards to certain of our employees and officers. Under the Plan, awards may be granted up to a maximum of 6,000,000 shares, if all awards granted are Full Value Awards, as defined, and up to 12,000,000 shares, if all of the awards granted are Not Full Value Awards, as defined, plus shares in respect of awards forfeited after May 2010 that were issued pursuant to our 2002 Omnibus Share 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. This means, for example, if the Committee were to award only restricted shares, it could award up to 6,000,000 restricted shares. On the other hand, if the Committee were to award only stock options, it could award options to purchase up to 12,000,000 shares (at the applicable exercise price). The Committee may also issue any combination of awards under the Plan, with reductions in availability of future awards made in accordance with the above limitations. As of December 31, 2013, we have approximately 4,672,000 shares available for future grants under the Plan, if all awards granted are Full Value Awards, as defined.
	In the years ended December 31, 2013, 2012 and 2011, we recognized an aggregate of $34,914,000, $30,588,000 and $28,853,000, respectively, of stock-based compensation expense, which is included as a component of “general and administrative” expenses on our consolidated statements of income. The details of the various components of our stock-based compensation are discussed below.
	Out-Performance Plans (“OPP Units”)
	On March 30, 2012 and March 15, 2013, the Committee approved the 2012 and 2013 Out-Performance Plans (the “OPPs”), respectively. The OPPs are multi-year, performance-based equity compensation plans under which participants, including our Chairman and Chief Executive Officer, have the opportunity to earn compensation payable in the form of equity awards if, and only if, we outperform a predetermined total shareholder return (“TSR”) and/or outperform the market with respect to a relative TSR in any year during the requisite performance periods as described below.   The aggregate notional amount of each of the OPPs is $40,000,000.
	Awards under the 2012 OPP may be earned if we (i) achieve a TSR level greater than 7% per annum, or 21% over the three-year performance period (the “Absolute Component”), and/or (ii) achieve a TSR above that of the SNL US REIT Index (the “Index”) over a one-year, two-year or three-year performance period (the “Relative Component”).  Awards under the 2013 OPP may be earned if we (i) achieve a TSR greater than 14% over the two-year performance measurement period, or 21% over the three-year performance measurement period (the “Absolute Component”), and/or (ii) achieve a TSR above that of the Index over a two-year or three-year performance measurement period (the “Relative Component”).  To the extent awards would be earned under the Absolute Component of each of the OPPs, but we underperform the Index, such awards would be reduced (and potentially fully negated) based on the degree to which we underperform the Index.  In certain circumstances, in the event we outperform the Index but awards would not otherwise be fully earned under the Absolute Component, awards may still be earned or increased under the Relative Component.  To the extent awards would otherwise be earned under the Relative Component but we fail to achieve at least a 6% per annum absolute TSR, such awards earned under the Relative Component would be reduced based on our absolute TSR, with no awards being earned in the event our TSR during the applicable measurement period is 0% or negative, irrespective of the degree to which we may outperform the Index.  Dividends on awards issued accrue during the performance period.
	If the designated performance objectives are achieved, OPP Units are subject to time-based vesting requirements. Awards earned under the OPPs vest 33% in year three, 33% in year four and 34% in year five. Our executive officers (for the purposes of Section 16 of the Exchange Act) are required to hold earned 2013 OPP awards for one year following vesting.
	The fair value of the 2012 and 2013 OPPs on the date of grant was $12,250,000, and $6,814,000, respectively. Such amounts are being amortized into expense over a five-year period from the date of grant, using a graded vesting attribution model. In the years ended December 31, 2013, 2012 and 2011, we recognized $3,226,000, $2,826,000 and $740,000, respectively, of compensation expense related to OPP Units. As of December 31, 2013, there was $10,065,000 of total unrecognized compensation cost related to the OPPs, which will be recognized over a weighted-average period of 1.9 years.
	15.       Stock-based Compensation - continued
	Stock Options
	Stock options are granted at an exercise price equal to the average of the high and low market price of our common shares on the NYSE on the date of grant, generally vest over four years and expire 10 years from the date of grant. Compensation expense related to stock option awards is recognized on a straight-line basis over the vesting period. In the years ended December 31, 2013, 2012 and 2011, we recognized $8,234,000, $8,638,000 and $8,794,000, respectively, of compensation expense related to stock options that vested during each year. As of December 31, 2013, there was $5,398,000 of total unrecognized compensation cost related to unvested stock options, which is expected to be recognized over a weighted-average period of 1.3 years.

	15.       Stock-based Compensation - continued
	Restricted Stock
	Restricted stock awards are granted at the average of the high and low market price of our common shares on the NYSE on the date of grant and generally vest over four years. Compensation expense related to restricted stock awards is recognized on a straight-line basis over the vesting period. In the years ended December 31, 2013, 2012 and 2011, we recognized $1,344,000, $1,604,000 and $1,814,000, respectively, of compensation expense related to restricted stock awards that vested during each year. As of December 31, 2013, there was $1,781,000 of total unrecognized compensation cost related to unvested restricted stock, which is expected to be recognized over a weighted-average period of 1.6 years. Dividends paid on unvested restricted stock are charged directly to retained earnings and amounted to $110,000, $200,000 and $185,000 for the years ended December 31, 2013, 2012 and 2011, respectively.

	Restricted Operating Partnership Units (“OP Units”)
	OP Units are granted at the average of the high and low market price of our 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. In the years ended December 31, 2013, 2012 and 2011, we recognized $22,110,000, $17,520,000 and $17,505,000, respectively, of compensation expense related to OP Units that vested during each year. As of December 31, 2013, there was $25,971,000 of total unrecognized compensation cost related to unvested OP Units, which is expected to be recognized over a weighted-average period of 1.8 years. Distributions paid on unvested OP Units are charged to “net income attributable to noncontrolling interests in the Operating Partnership” on our consolidated statements of income and amounted to $2,598,000, $3,203,000 and $2,567,000 in the years ended December 31, 2013, 2012 and 2011, respectively.

Leases [Text Block]	'
	20.       Leases
	As lessor:
	We lease space to tenants under operating leases. Most of the leases provide for the payment of fixed base rentals payable monthly in advance. Office building leases generally require the tenants to reimburse us for operating costs and real estate taxes above their base year costs. Shopping center leases provide for pass-through to tenants the tenant's share of real estate taxes, insurance and maintenance. Shopping center leases also provide for the payment by the lessee of additional rent based on a percentage of the tenants' sales. As of December 31, 2013, future base rental revenue under non-cancelable operating leases, excluding rents for leases with an original term of less than one year and rents resulting from the exercise of renewal options, are as follows:
		(Amounts in thousands)
		Year Ending December 31:
		2014	$	1,811,280

		2017		1,406,377
		2018		1,272,529
		Thereafter		6,529,277
	These amounts do not include percentage rentals based on tenants' sales. These percentage rents approximated $8,796,000, $8,466,000 and $7,995,000, for the years ended December 31, 2013, 2012 and 2011, respectively.
	Excluding the $59,599,000 of income pursuant to a settlement agreement with Stop & Shop in the year ended December 31, 2013, none of our tenants accounted for more than 10% of total revenues in any of the years ended December 31, 2013, 2012 and 2011.

	We are also a lessee under a capital lease under which we will redevelop the retail and signage components of the Marriot Marquis Times Square Hotel. The lease has put/call options, which if exercised would lead to our ownership. Capitalized leases are recorded at the present value of future minimum lease payments or the fair market value of the property. Capitalized leases are depreciated on a straight-line basis over the estimated life of the asset or life of the related lease. Depreciation expense on capital leases is included in “depreciation and amortization” on our consolidated statements of income. As of December 31, 2013, future minimum lease payments under this capital lease are as follows:

	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, 2013, our subsidiaries' participation in these plans were not significant to our consolidated financial statements.
	In the years ended December 31, 2013, 2012 and 2011, our subsidiaries contributed $10,223,000, $10,683,000 and $10,168,000, 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, 2013, 2012 and 2011.
	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, 2013, 2012 and 2011, our subsidiaries contributed $26,262,000, $26,759,000 and $23,847,000, respectively, towards these plans, which is included as a component of “operating” expenses on our consolidated statements of income.

	Insurance
	We maintain general liability insurance with limits of $300,000,000 per occurrence and all risk property and rental value insurance with limits of $2.0 billion per occurrence, with sub-limits for certain perils such as floods. Our California properties have earthquake insurance with coverage of $180,000,000 per occurrence, subject to a deductible in the amount of 5% of the value of the affected property, up to a $180,000,000 annual aggregate. We maintain coverage for terrorism acts with limits of $4.0 billion per occurrence and in the aggregate, and $2.0 billion per occurrence and in the aggregate for terrorism involving nuclear, biological, chemical and radiological (“NBCR”) terrorism events, as defined by Terrorism Risk Insurance Program Reauthorization Act, which expires in December 2014.
	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 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 $3,200,000 and 15% of the balance of a covered loss and the Federal government is responsible for the remaining 85% of a covered loss. We are ultimately responsible for any loss incurred by PPIC.
	We continue to monitor the state of the insurance market and the scope and costs of coverage for acts of terrorism. However, we cannot anticipate what coverage will be available on commercially reasonable terms in the future.
	Our debt instruments, consisting of mortgage loans secured by our properties which are non-recourse to us, 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 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 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.
	Our mortgage loans are non-recourse to us. However, 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. As of December 31, 2013, the aggregate dollar amount of these guarantees and master leases is approximately $342,000,000.
	At December 31, 2013, $33,121,000 of letters of credit were outstanding under one of our revolving credit facilities. Our 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 revolving credit facilities also contain customary conditions precedent to borrowing, including representations and warranties, and also contain customary events of default that could give rise to accelerated repayment, including such items as failure to pay interest or principal.
	As of December 31, 2013, we expect to fund additional capital to certain of our partially owned entities aggregating approximately $145,000,000.

	We manage and lease the real estate assets of Interstate pursuant to a management agreement for which we receive an annual fee equal to 4% of annual base rent and percentage rent. The management agreement has a term of one year and is automatically renewable unless terminated by either of the parties on 60 days' notice at the end of the term. We believe, based upon comparable fees charged by other real estate companies, that the management agreement terms are fair to us. We earned $606,000, $794,000, and $787,000 of management fees under the agreement for the years ended December 31, 2013, 2012 and 2011.

	2014 Out-Performance Plan
	On January 10, 2014, the Compensation Committee approved the 2014 Outperformance Plan, a multi-year, performance-based equity compensation plan and related form of award agreement (the “2014 OPP”). Under the 2014 OPP, participants have the opportunity to earn compensation payable in the form of operating partnership units during a three-year performance measurement period, if and only if we outperform a predetermined total shareholder return (“TSR”) and/or outperform the market with respect to relative TSR. Awards under the 2014 OPP may be earned if we (i) achieve a TSR level greater than 7% per annum, or 21% over the three-year performance measurement period (the “Absolute Component”), and/or (ii) achieve a TSR above that of the SNL US REIT Index (the “Index”) over a three-year performance measurement period (the “Relative Component”). To the extent awards would be earned under the Absolute Component but we underperform the Index, such awards earned under the Absolute Component would be reduced (and potentially fully negated) based on the degree to which we underperform the Index. In certain circumstances, in the event we outperform the Index but awards would not otherwise be earned under the Absolute Component, awards may be increased under the Relative Component. To the extent awards would otherwise be earned under the Relative Component but we fail to achieve at least a 6% per annum absolute TSR, such awards earned under the Relative Component would be reduced based on our absolute TSR, with no awards being earned in the event our TSR during the applicable measurement period is 0% or negative, irrespective of the degree to which we may outperform the Index. If the designated performance objectives are achieved, OPP Units are also subject to time-based vesting requirements. Awards earned under the 2014 OPP vest 33% in year three, 33% in year four and 34% in year five. Dividends on awards earned accrue during the performance measurement period. In addition, our executive officers (for the purposes of Section 16 of the Exchange Act) are required to hold any earned OPP awards (or related equity) for at least one year following vesting.
	220 Central Park South Development Site
	On January 31, 2014, we completed a $600,000,000 loan secured by our 220 Central Park South development site. The loan bears interest at LIBOR plus 2.75% and matures in January 2016, with three one-year extension options.

	As a result of certain organizational changes and asset sales in 2012, the Merchandise Mart segment no longer met the criteria to be a separate reportable segment; accordingly, effective January 1, 2013, the remaining assets were reclassified to “Other.” We have also reclassified the prior period segment financial results to conform to the current year presentation. Below is a summary of net income and a reconciliation of net income to EBITDA(1) by segment for the years ended December 31, 2013, 2012 and 2011.

26. Segment Information – continued
	Notes to preceding tabular information:
-1	EBITDA represents "Earnings Before Interest, Taxes, Depreciation and Amortization." We consider EBITDA a supplemental 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 a multiple of EBITDA, we utilize this measure to make investment decisions as well as to compare the performance of our assets to that of our peers. EBITDA should not be considered a substitute for net income. EBITDA may not be comparable to similarly titled measures employed by other companies.
-2	Interest and debt expense, depreciation and amortization and income tax expense (benefit) in the reconciliation of net income (loss) to EBITDA includes our share of these items from partially owned entities.

Basis of Presentation and Significant Accounting Policies [Abstract]	'
Basis of Presentation Policy	'
	Basis of Presentation
	The accompanying consolidated financial statements include the accounts of Vornado and its consolidated subsidiaries, including the Operating Partnership. 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, 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.
New Accounting Pronouncements Policy [Policy Text Block]	'
	Recently Issued Accounting Literature
	In February 2013, the Financial Accounting Standards Board (“FASB”) issued an update (“ASU 2013-02”) to Accounting Standards Codification (“ASC”) Topic 220, Comprehensive Income (“Topic 220”). ASU 2013-02 requires additional disclosures regarding significant reclassifications out of each component of accumulated other comprehensive income, including the effect on the respective line items of net income for amounts that are required to be reclassified into net income in their entirety and cross-references to other disclosures providing additional information for amounts that are not required to be reclassified into net income in their entirety. The adoption of this update as of January 1, 2013, did not have a material impact on our consolidated financial statements, but resulted in additional disclosures (see Note 12 – Shareholders' Equity – Accumulated Other Comprehensive Income (Loss)).
	In June 2013, the FASB issued an update (“ASU 2013-08”) to ASC Topic 946, Financial Services - Investment Companies (“Topic 946”). ASU 2013-08 amends the guidance in Topic 946 for determining whether an entity qualifies as an investment company and requires certain additional disclosures. ASU 2013-08 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2013. The adoption of this update as of January 1, 2014, did not have any impact on our real estate fund and our consolidated financial statements.
Real Estate [Policy Text Block]	'
	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 redeveloped property, the excess is charged to expense. Depreciation is recognized on a straight-line basis over 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.
	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. 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 record acquired intangible assets (including acquired above-market leases, acquired in-place leases and tenant relationships) and acquired intangible liabilities (including below–market leases) at their estimated fair value separate and apart from goodwill. 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.
	2. Basis of Presentation and Significant Accounting Policies - continued
	Our properties, including any related 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, anticipated holding periods, 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 cash flows is subjective and is based, in part, on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results. Plans to hold properties over longer periods decrease the likelihood of recording impairment losses.
	Allowance for Doubtful Accounts: We periodically evaluate the collectibility of amounts due from tenants and maintain an allowance for doubtful accounts for estimated losses resulting from the inability of tenants to make required payments under the lease agreements. We also maintain an allowance for receivables arising from the straight-lining of rents. This receivable arises from earnings recognized in excess of amounts currently due under the lease agreements. Management exercises judgment in establishing these allowances and considers payment history and current credit status in developing these estimates.
Partially Owned Entities [Policy Text Block]	'
	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 factors such as ownership interest, board representation, management representation, authority to make decisions, and contractual and substantive participating rights of the partners/members as well as whether the entity is a variable interest entity (“VIE”) and we are the primary beneficiary. 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 entity is not considered a VIE and the approval of all of the partners/members is contractually required with respect to major decisions, such as operating and capital budgets, the sale, exchange or other disposition of real property, the hiring of a chief executive officer, the commencement, compromise or settlement of any lawsuit, legal proceeding or arbitration or the placement of new or additional financing secured by assets of the venture. 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 on the cost method.
	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 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.
Mezzanine Loans Receivable [Policy Text Block]	'
	Mortgage and Mezzanine Loans Receivable: We invest in mortgage and mezzanine loans of entities that have significant real estate assets. These investments are either secured by the real property or by pledges of the equity interests of the entities owning the underlying real estate. We record these investments at the stated principal amount net of any unamortized discount or premium. We accrete or amortize any discount or premium over the life of the related receivable utilizing the effective interest method or straight-line method, if the result is not materially different. We evaluate the collectibility of both interest and principal of each of our loans whenever events or changes in circumstances indicate such amounts may not be recoverable. A loan is impaired when it is probable that we will be unable to collect all amounts due according to the existing contractual terms. When a loan is impaired, the amount of the loss accrual is calculated by comparing the carrying amount of the investment to the present value of expected future cash flows discounted at the loan's effective interest rate, or as a practical expedient, to the value of the collateral if the loan is collateral dependent. Interest on impaired loans is recognized when received in cash.
Cash And Cash Equivalents [Policy Text Block]	'
	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 (“CDARS”).
Cash And Cash Equivalents Restricted Cash And Cash Equivalents Policy	'
	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 for debt service, real estate taxes, property insurance and capital improvements.
Deferred Charges [Policy Text Block]	'
	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.
Revenue Recognition [Policy Text Block]	'
	Revenue Recognition: We have the following revenue sources and revenue recognition policies:
	•       Base Rent — income arising from tenant leases. These rents are recognized over the non-cancelable term of the related leases on a straight-line basis which includes the effects of rent steps and rent abatements under the leases. We commence rental revenue recognition when the tenant takes possession of the leased space and the leased space is substantially ready for its intended use. In addition, in circumstances where we provide a tenant improvement allowance for improvements that are owned by the tenant, we recognize the allowance as a reduction of rental revenue on a straight-line basis over the term of the lease.
	•       Percentage Rent — income arising from retail tenant leases that is contingent upon tenant sales exceeding defined thresholds. These rents are recognized only after the contingency has been removed (i.e., when tenant sales thresholds have been achieved).
	•       Hotel Revenue — income arising from the operation of the Hotel Pennsylvania which consists of rooms revenue, food and beverage revenue, and banquet revenue. Income is recognized when rooms are occupied. Food and beverage and banquet revenue is recognized when the services have been rendered.
	•       Trade Shows Revenue — income arising from the operation of trade shows, including rentals of booths. This revenue is recognized when the trade shows have occurred.
	•       Expense Reimbursements — revenue arising from tenant leases which provide for the recovery of all or a portion of the operating expenses and real estate taxes of the respective property. This revenue is accrued in the same periods as the expenses are incurred.
	•       Management, Leasing and Other Fees — income arising from contractual agreements with third parties or with partially owned entities. This revenue is recognized as the related services are performed under the respective agreements.
	•       Cleveland Medical Mart — revenue arising from the development of the Cleveland Medical Mart. This revenue was recognized as the related services were performed under the respective agreements using the criteria set forth in ASC 605-25, Multiple Element Arrangements
Income Tax [Policy Text Block]	'
	Income Taxes: We operate in a manner intended to enable us 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. We distribute to shareholders 100% of taxable income and therefore, no provision for Federal income taxes is required. Dividends distributed for the year ended December 31, 2013, were characterized, for federal income tax income tax purposes, as ordinary income. Dividend distributions for the year ended December 31, 2012, were characterized, for Federal income tax purposes, as 62.7% ordinary income and 37.3% long-term capital gain. Dividend distributions for the year ended December 31, 2011 were characterized, for Federal income tax purposes, as 93.2% ordinary income and 6.8% long-term capital gain.
	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.
Marketable Securities [Policy Text Block]	'
	Our portfolio of marketable securities is comprised of equity securities that are classified as available-for-sale. Available-for-sale securities are presented on our consolidated balance sheets at fair value. Unrealized gains and losses resulting from the mark-to-market of these securities are included in “other comprehensive income (loss).” Realized gains and losses are recognized in earnings only upon the sale of the securities and are recorded based on the weighted average cost of such securities.
	We evaluate our portfolio of marketable securities for impairment each reporting period. For each of the securities in our portfolio with unrealized losses, we review the underlying cause of the decline in value and the estimated recovery period, as well as the severity and duration of the decline. In our evaluation, we consider our ability and intent to hold these investments for a reasonable period of time sufficient for us to recover our cost basis. We also evaluate the near-term prospects for each of these investments in relation to the severity and duration of the decline.
Redeemable Noncontrolling Interests Policy [Text Block]	'
	11. Redeemable Noncontrolling Interests
	Redeemable noncontrolling interests on our consolidated balance sheets 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 our consolidated statements of changes in equity. Class A units may be tendered for redemption to the Operating Partnership for cash; we, at our 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.
	Redeemable noncontrolling interests exclude our Series G Convertible Preferred units and Series D-13 Cumulative Redeemable Preferred units, as they are accounted for as liabilities in accordance with ASC 480, Distinguishing Liabilities and Equity, because of their possible settlement by issuing a variable number of Vornado common shares.

This basis difference results primarily from non-cash impairment losses aggregating $280,757,000 that we recognized in 2013 and 2012. We have allocated the basis difference to Toys' real estate (which will be amortized over its estimated useful life), and intangible assets, primarily trade names and trademarks (which is not being amortized and will be recognized upon disposition of our investment).

	Notes to preceding tabular information:
-1	EBITDA represents "Earnings Before Interest, Taxes, Depreciation and Amortization." We consider EBITDA a supplemental 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 a multiple of EBITDA, we utilize this measure to make investment decisions as well as to compare the performance of our assets to that of our peers. EBITDA should not be considered a substitute for net income. EBITDA may not be comparable to similarly titled measures employed by other companies.
-2	Interest and debt expense, depreciation and amortization and income tax expense (benefit) in the reconciliation of net income (loss) to EBITDA includes our share of these items from partially owned entities.
