Basis Of Presentation	2 . Basis of Presentation The accompanying consolidated financial statements are unaudited and include the accounts of Vornado and its consolidated subsidiaries, including the Operating Partnership . All inter - company amounts have been eliminated. In our opinion, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations and changes in cash flows have been made. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted. These condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q of the Securities and Exchange Commission (“ SEC ”) and should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K, as amended, for the year ended December 31, 2015 , as fi led with the SEC. We have made estimates and assumptions that affect the reported amounts of assets and liabilities , disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. The results of operations for the three and six months ended June 30, 2016 are not necessarily indicative of the operating results for the full year .

Recently Issued Accounting Literature [Abstract]
Recently Issued Accounting Literature	3 . Recently Issued Accounting Literature In May 2014, the Financial Accounting Standards Board (“ FASB ”) issued an update ("ASU 2014-09") establishing Accounting Standards Codification (“ ASC ”) Topic 606, Revenue from Contracts with Customers (“ASC 606”) . ASU 2014-09 establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most of the existing revenue recognition guidance. ASU 2014-09 requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and also requires certain additional disclosures. In August 2015, the FASB issued an update (“ASU 2015 -14”) to ASC 606, Deferral of the Effective Date , which defers the adoption of ASU 2014-09 to interim and annual reporting periods in fiscal years that begin after December 15, 2017 . In March 2016, the FASB issued an update (“ASU 2016-08”) to ASC 606, Pri ncipal versus Agent Considerations (Reporting Revenue Gross versus Net) , which clarifies the implementation guidance on principal versus agent considerations in the new revenue recognition standard pursuant to ASU 2014-09. In April 2016, the FASB issued a n update (“ASU 2016-10”) to ASC 606, Identifying Performance Obligations and Licensing , which clarifies guidance related to identifying performance obligations and licensing implementation guidance contained in ASU 2014-09. In May 2016, the FASB issued an update (“ASU 2016-12”) to ASC 606, Narrow-Scope Improvements and Practical Expedients , which amends certain aspects of the new revenue recognition standard pursuant to ASU 2014-09. We are currently evaluating the impac t of the adoption of these ASUs on o ur consolidated financial statements. In June 2014, the FASB issued an update (“ASU 2014-12”) to ASC Topic 718, Compensation – Stock Compensation (“ASC 718”) . ASU 2014-12 requires an entity to treat performance targets that can be met after the requisite service period of a share based award has ended, as a performance condition that affects vesting. ASU 2014-12 is effective for interim and annual reporting periods in fiscal years that began after December 15, 2015. The adoption of this update as of January 1, 2016, did not have any impact on our consolidated financial statements. In February 2015, the FASB issued an update (“ASU 2015-02”) Amendments to the Consolidation Analysis to ASC Topic 810, Consolidation . ASU 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. Specifically, the amendments: (i) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIEs") or voting interest entities, (ii) eliminate the presumption that a general partner should consolidate a limited partnership, (iii) affect the consolidation analysis of reporting entities that are involved with VIEs, and (iv) provide a scope exception for certain entities. ASU 2015-02 is effective for interim and annual reporting periods beginn ing after December 15, 2015. The adoption of this update on January 1, 2016 resulted in the identification of additional VIEs, but did not have an impact on our consolidated financial statements other than additional disclosures (see Note 13 - Var iab le Interest Entities ) . In January 2016, the FASB issued an update (“ASU 2016-01”) Recognition and Measurement of Financial Assets and Financial Liabilities to ASC Topic 825, Financial Instruments . ASU 2016-01 amends certain aspects of recognition, measurement, presentation and disclosure of financial instruments, including the requirement to measure certain equity investments at fair value with changes in fair value recognized in net income. ASU 2016-01 is effective for interim and annual reporting periods in fiscal years begi nning after December 15, 2017. We are currently evaluating the impact of the adoption of ASU 2016-01 on our consolidated financial statements. In February 2016, the FASB issued (“ASU 2016-02”) Leases , 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 dual 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 asset and a lease liability for all leases with a term of greater than 12 months. Leases with a term of 12 months or less will be a ccounted for similar to existing guidance for operating leases. Lessees will recognize expense based on the effective interest method for finance leases or on a straight-line basis for operating leases. The new standard requires lessors to account for le ases using an approach that is substantially equivalent to existing guidance. ASU 2016-02 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact of the adoption of ASU 2 016-02 on our consolidated financial statements. In March 2016, the FASB issued an update (“ASU 2016-09”) Improvements to Employee Share-Based Payment Accounting to ASC 718. ASU 2016-09 amends several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. We are currently evaluating the impact of the adoption of ASU 2016-09 on our consolidated financial statements.

The loan , which bears interest at LIBOR plus 3.00 % (3.47% at June 30, 2016) , matures in May 2019 with two one-y ear extension options. Because this joint venture is a VIE and we determined we are the primary beneficiary, we consolidate the accounts of this joint venture from the date of our investment.

The Company realized net proceeds of approximately $330,000,000. The property was previously encumbered by a 5.65%, $353,000, 000 mortgage which matured in March 2016. On March 15, 2016, we notified the servicer of the $678,000,000 mortgage loan on the Skyline properties in Virginia that cash flow will be insufficient to service the debt and pay other property related costs and expenses and that we were not willing to fund additional cash shortfalls. Accordingly, at our request, the loan has been transferred to the special servicer. Consequently, based on our shortened estimated holding period for the underlying assets, we concluded that the excess of carrying amount o ver our estimate of fair value was not recoverable and recognized a $ 160,700,000 non-cash impairment loss in the first quarter of 2016. The Company’s estimate of fair value was derived from a discounted cash flow model based upon market conditions a nd expectations of growth and utilized unobservable quantitative inputs including a capitalization rate of 8.0% and a discount rate of 8.2%. In the second quarter of 2016, cash flow became insufficient to service the debt and w e ceased making debt service payments . Pursuant to the loan agreement , the loan is in default, causing the loan to be immediately due and payable, and is subject to incremental default interest which increased the weighted average interest rate from 2.97% to 4.51% while the outstand ing balance remains unpaid. For the three and six months ended June 30, 2016 , we accrued $ 2,711,000 of default interest expense . We continue to negotiate with the special servicer. T here can be n o assurance as to the timing or ultimate resolution of th is matter . The following is a summary of our debt : (Amounts in thousands) Interest Rate at Balance at June 30, 2016 June 30, 2016 December 31, 2015 Mortgages Payable: Fixed rate 4.17 % $ 6,571,398 $ 6,356,634 Variable rate 2.28 % 3,281,935 3,258,204 Total 3.54 % 9,853,333 9,614,838 Deferred financing costs, net and other (106,515) (101,125) Total, net $ 9,746,818 $ 9,513,713 Unsecured Debt: Senior unsecured notes 3.68 % $ 850,000 $ 850,000 Deferred financing costs, net and other (5,132) (5,841) Senior unsecured notes, net 844,868 844,159 Unsecured term loan 1.61 % 375,000 187,500 Deferred financing costs, net and other (3,545) (4,362) Unsecured term loan, net 371,455 183,138 Unsecured revolving credit facilities 1.51 % 115,630 550,000 Total, net $ 1,331,953 $ 1,577,297

Redeemable Noncontrolling Interests	11. Redeemable Noncontrolling Interests Redeemable noncontrolling interests on our consolidated balance sheets are comprised primarily 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. Below is a table summarizing the activity of redeemable noncontrolling interests.

Redeemable noncontrolling interests 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 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 June 30, 2016 and December 31, 2015 .

Variable Interest Entities [Abstract]
Variable Interest Entities ("VIEs")	13. Variable Interest Entities At June 30, 2016 and December 31, 2015, we have several unconsolidated VIEs . We do not consolidate these entities because we are not the primary beneficiary and the nature of our involvement in the activities of these entities does not give us power over decisions that significantly affect these entities’ economic performance. We account for our investment in these entities under the equity method (see Note 7 – Investments in Partially Owned Entities ). As of June 30, 2016 and December 31, 2015, the net carrying amounts of our investment in these entities were $ 394,866,000 and $ 379,939,000 , respectively, and our maximum exposure to loss in these entities, is limited to our investments. We adopted ASU 2015-02 on January 1, 2016 which resulted in the identification of several VIEs at June 30, 2016 . Prior to the adoption of ASU 2015-02, these entities were consolidated under the voting interest model. Our most significant consolidated VIEs are our Operating Partnership, real estate fund investments, 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. We conduct our business through, and all of our assets and liabilities are held by, our Operating Partnership which is a VIE.

Fair Value Disclosures [Abstract]
Fair Value Measurements	14. 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 pri ces (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 o bservable 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 thes e assets. Financial Assets and Li abilities Measured at Fair Value on a Recurring Basis Financial assets and liabilities t hat are measured at fair value o n our consolidated balance sheets consist of (i) marketable securities, (ii) r eal e state f und inv estments , (iii) the assets in our deferred compensation plan (for which there is a corresponding liability on our consolidated balance sheet) , (iv) mandatorily redeemable instruments (Series G-1 through G-4 convertible preferred units and Series D-13 cumul ative redeemable preferred units) , and (v) interest rate swaps . The tables below aggregate the fair values of these financial assets and liabilities by their level s in the fair value hierarchy as of June 30, 2016 and December 3 1, 2015 , respectively.

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 update d 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 1.0 to 4.5 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 th e 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 d iscount 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 capitalizatio n rates and discount rates. These rates are based on the location, type and nature of each property, and current and anticipated market conditions, industry publications and from the experience of our Acquisitions and Capital Markets departments. Signifi cant unobservable quantitative inputs in the table below were utilized in determining the fair value of these real estate fund investments at June 30, 2016 and December 31, 2015 . Weighted Average Range (based on fair value of investments) Unobservable Quantitative Input June 30, 2016 December 31, 2015 June 30, 2016 December 31, 2015 Discount rates 12.0% to 14.9% 12.0% to 14.9% 13.7% 13.6% Terminal capitalization rates 4.8% to 6.1% 4.8% to 6.1% 5.5% 5.5% 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 resulti ng 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 summar izes the changes in the fair value of real estate fund i nvestments that are classified as Level 3, for the three and six months ended June 30, 2016 and 2015 .

We receive quarterly financial reports from a third-party administrator, which are compiled from the quarterly reports provided to them from ea ch 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 de termining our share of the net assets and we do not adjust these values when report ed in our consolidated financial statements .

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 curve s to project the expected cash flows we would be required to make under the instrument.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	20. Commitments and Contingencies Insurance 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 $180,000,000 per occurrence and in the annual aggregate, subject to a deductible in the amount of 5% of the value of the affect ed property. 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”) terro rism events, as defined by Terrorism Risk Insurance Program Reauthorization Act of 2015, which expires in December 2020. 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 responsib le for a deductible of $2,400,000 per occurrence and 16% of the balance of a covered loss and the Federal government is responsible for the remaining 84% of a covered loss. We are ultimately responsible for any loss incurred by PPIC. We continue to monit or 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 loa ns 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 t hese 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 t o 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 m aterial 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 woul d not result in significant costs to us. Generally, o ur 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 specifi ed circumstances or repayment of the underlying loans. As of June 30, 2016 , the aggregate dollar amount of these guarantees and master leases is approximately $857,000,000 . At June 30, 2016 , $38,576,000 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 t o market capitalization ratios, and provide for higher interest rates in the event of a decline in our ratings below Baa3/BBB. Our unsecured revolving credit facilities also contain customary conditions precedent to borrowing, including representations and warranties, and also contain customary events of default that could give rise to accelerated repayment, including such items as failure to pay interest or principal. As of June 30, 2016 , we expect to fund additional capital to certain of our partially owned entities aggregating approximately $70,000,000 . As of June 30, 2016 , we have construction commitments aggregating approximately $721,173,000 .

Notes to preceding tabular information: (1) EBITDA represents "Earnings Before Interest, Taxes, Depreciation and Amortization." We consider EBITDA a 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 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 [Abstract]
Basis of Presentation [Policy Text Block]	The accompanying consolidated financial statements are unaudited and include the accounts of Vornado and its consolidated subsidiaries, including the Operating Partnership . All inter - company amounts have been eliminated. In our opinion, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations and changes in cash flows have been made. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted. These condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q of the Securities and Exchange Commission (“ SEC ”) and should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K, as amended, for the year ended December 31, 2015 , as fi led with the SEC. We have made estimates and assumptions that affect the reported amounts of assets and liabilities , disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. The results of operations for the three and six months ended June 30, 2016 are not necessarily indicative of the operating results for the full year .
Recently Issued Accounting Literature [Policy Text Block]	3 . Recently Issued Accounting Literature In May 2014, the Financial Accounting Standards Board (“ FASB ”) issued an update ("ASU 2014-09") establishing Accounting Standards Codification (“ ASC ”) Topic 606, Revenue from Contracts with Customers (“ASC 606”) . ASU 2014-09 establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most of the existing revenue recognition guidance. ASU 2014-09 requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and also requires certain additional disclosures. In August 2015, the FASB issued an update (“ASU 2015 -14”) to ASC 606, Deferral of the Effective Date , which defers the adoption of ASU 2014-09 to interim and annual reporting periods in fiscal years that begin after December 15, 2017 . In March 2016, the FASB issued an update (“ASU 2016-08”) to ASC 606, Pri ncipal versus Agent Considerations (Reporting Revenue Gross versus Net) , which clarifies the implementation guidance on principal versus agent considerations in the new revenue recognition standard pursuant to ASU 2014-09. In April 2016, the FASB issued a n update (“ASU 2016-10”) to ASC 606, Identifying Performance Obligations and Licensing , which clarifies guidance related to identifying performance obligations and licensing implementation guidance contained in ASU 2014-09. In May 2016, the FASB issued an update (“ASU 2016-12”) to ASC 606, Narrow-Scope Improvements and Practical Expedients , which amends certain aspects of the new revenue recognition standard pursuant to ASU 2014-09. We are currently evaluating the impac t of the adoption of these ASUs on o ur consolidated financial statements. In June 2014, the FASB issued an update (“ASU 2014-12”) to ASC Topic 718, Compensation – Stock Compensation (“ASC 718”) . ASU 2014-12 requires an entity to treat performance targets that can be met after the requisite service period of a share based award has ended, as a performance condition that affects vesting. ASU 2014-12 is effective for interim and annual reporting periods in fiscal years that began after December 15, 2015. The adoption of this update as of January 1, 2016, did not have any impact on our consolidated financial statements. In February 2015, the FASB issued an update (“ASU 2015-02”) Amendments to the Consolidation Analysis to ASC Topic 810, Consolidation . ASU 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. Specifically, the amendments: (i) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIEs") or voting interest entities, (ii) eliminate the presumption that a general partner should consolidate a limited partnership, (iii) affect the consolidation analysis of reporting entities that are involved with VIEs, and (iv) provide a scope exception for certain entities. ASU 2015-02 is effective for interim and annual reporting periods beginn ing after December 15, 2015. The adoption of this update on January 1, 2016 resulted in the identification of additional VIEs, but did not have an impact on our consolidated financial statements other than additional disclosures (see Note 13 - Var iab le Interest Entities ) . In January 2016, the FASB issued an update (“ASU 2016-01”) Recognition and Measurement of Financial Assets and Financial Liabilities to ASC Topic 825, Financial Instruments . ASU 2016-01 amends certain aspects of recognition, measurement, presentation and disclosure of financial instruments, including the requirement to measure certain equity investments at fair value with changes in fair value recognized in net income. ASU 2016-01 is effective for interim and annual reporting periods in fiscal years begi nning after December 15, 2017. We are currently evaluating the impact of the adoption of ASU 2016-01 on our consolidated financial statements. In February 2016, the FASB issued (“ASU 2016-02”) Leases , 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 dual 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 asset and a lease liability for all leases with a term of greater than 12 months. Leases with a term of 12 months or less will be a ccounted for similar to existing guidance for operating leases. Lessees will recognize expense based on the effective interest method for finance leases or on a straight-line basis for operating leases. The new standard requires lessors to account for le ases using an approach that is substantially equivalent to existing guidance. ASU 2016-02 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact of the adoption of ASU 2 016-02 on our consolidated financial statements. In March 2016, the FASB issued an update (“ASU 2016-09”) Improvements to Employee Share-Based Payment Accounting to ASC 718. ASU 2016-09 amends several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. We are currently evaluating the impact of the adoption of ASU 2016-09 on our consolidated financial statements.
Real Estate Fund Investments [Policy Text Block]	The Fund is accounted for under ASC 946, Financial Services – Investment Companies (“ASC 946”) and its investments are reported on its balance sheet at fair value, with changes in value each period recognized in earnings. We consolidate the accounts of the Fund into our consolidated financial statements, retaining the fair value basis of accounting.
Redeemable Noncontrolling Interests [Policy Text Block]	Redeemable noncontrolling interests on our consolidated balance sheets are comprised primarily 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. Redeemable noncontrolling interests 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 480, Distinguishing Liabilities and Equity , because of their possible settlement by issuing a variable number of Vornado common shares.
Fair Value Measurement [Policy Text Block]	In determining fair value, we utilize valuation techniques that maximize the use of o bservable 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 thes e assets. Financial Assets and Li abilities Measured at Fair Value on a Recurring Basis Financial assets and liabilities t hat are measured at fair value o n our consolidated balance sheets consist of (i) marketable securities, (ii) r eal e state f und inv estments , (iii) the assets in our deferred compensation plan (for which there is a corresponding liability on our consolidated balance sheet) , (iv) mandatorily redeemable instruments (Series G-1 through G-4 convertible preferred units and Series D-13 cumul ative redeemable preferred units) , and (v) interest rate swaps . 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 curve s 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 and unsecured debt is c lassifie d as Level 2 .

Notes to preceding tabular information: (1) EBITDA represents "Earnings Before Interest, Taxes, Depreciation and Amortization." We consider EBITDA a 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 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.
