1. Organization

Vornado Realty Trust (“Vornado”) is a fully-integrated real estate investment trust (“REIT”) and conducts its business through, and substantially all of its interests in properties are held by, Vornado Realty L.P., a Delaware limited partnership (the “Operating Partnership”). Vornado is the sole general partner of, and owned approximately 94.0% of the common limited partnership interest in, the Operating Partnership at June 30, 2015. All references to “we,” “us,” “our,” the “Company” and “Vornado” refer to Vornado Realty Trust and its consolidated subsidiaries, including the Operating Partnership.

On January 15, 2015, we completed the spin-off of substantially all of our retail segment comprised of 79 strip shopping centers, three malls, a warehouse park and $225,000,000 of cash to Urban Edge Properties (“UE”) (NYSE: UE). As part of this transaction, we retained 5,717,184 UE operating partnership units (5.4% ownership interest). We are providing transition services to UE for an initial period of up to two years, including information technology, human resources, tax and financial reporting. UE is providing us with leasing and property management services for (i) the Monmouth Mall, (ii) certain small retail properties that we plan to sell, and (iii) our affiliate, Alexander's, Inc. (NYSE: ALX), Rego Park retail assets. Steven Roth, our Chairman and Chief Executive Officer is a member of the Board of Trustees of UE. The spin-off distribution was effected by Vornado distributing one UE common share for every two Vornado common shares. Beginning in the first quarter of 2015, the historical financial results of UE are reflected in our consolidated financial statements as discontinued operations for all periods presented.

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 intercompany 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 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, 2014, as filed 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, 2015 are not necessarily indicative of the operating results for the full year.

Certain prior year balances have been reclassified in order to conform to the current period presentation. Beginning in the three months ended March 31, 2015, the Company classifies signage revenue within “property rentals”. For the three and six months ended June 30, 2014, $8,873,000 and $18,191,000, respectively, related to signage revenue has been reclassified from “fee and other income” to “property rentals” to conform to the current period presentation.

Significant Accounting Policies

Condominium Units Held For Sale: Pursuant to ASC 605-35-25-88, Revenue Recognition: Completed Contract Method, revenue from condominium unit sales is recognized upon closing of the sale, as all conditions for full profit recognition have not been met until that time. We use the relative sales value method to allocate costs to individual condominium units.

We are constructing a residential condominium tower containing 392,000 salable square feet on our 220 Central Park South (“220 CPS”) development site. As of June 30, 2015, we had entered into agreements to sell approximately 40% of the project for aggregate sales proceeds of $1.4 billion. In connection therewith, $209,902,000 of deposits are held with a third party escrow agent.

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 our shareholders 100% of our taxable income and therefore, no provision for Federal income taxes is required.

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.

At June 30, 2015 and December 31, 2014, our taxable REIT subsidiaries had deferred tax assets of $95,419,000 and $94,100,000, respectively, which are included in “other assets” on our consolidated balance sheets. Prior to the quarter ended June 30, 2015, there was a full valuation allowance against our deferred tax assets because we had not determined that it is more-likely-than-not that we would use the net operating loss carryforwards to offset future taxable income. During the second quarter of 2015, we began to enter into agreements to sell residential condominium units at 220 CPS and as of June 30, 2015, we had entered into agreements to sell approximately 40% of the project for aggregate sales proceeds of $1.4 billion. Based on these agreements, among other factors, we have concluded that it is more-likely-than-not that we will generate sufficient taxable income to realize the deferred tax assets. Accordingly, during the second quarter of 2015, we reversed $90,030,000 of the allowance for deferred tax assets and recognized an income tax benefit in our consolidated statements of income in the three and six months ended June 30, 2015.

3. Recently Issued Accounting Literature

In April 2014, the Financial Accounting Standards Board (“FASB”) issued an update (“ASU 2014-08”) Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity to ASC Topic 205, Presentation of Financial Statements and ASC Topic 360, Property Plant and Equipment. Under ASU 2014-08, only disposals that represent a strategic shift that has (or will have) a major effect on the entity's results and operations would qualify as discontinued operations. In addition, ASU 2014-08 expands the disclosure requirements for disposals that meet the definition of a discontinued operation and requires entities to disclose information about disposals of individually significant components that do not meet the definition of discontinued operations. ASU 2014-08 is effective for interim and annual reporting periods in fiscal years that began after December 15, 2014. Upon adoption of this standard on January 1, 2015, individual properties sold in the ordinary course of business are not expected to qualify as discontinued operations. The financial results of UE and certain other retail assets are reflected in our consolidated financial statements as discontinued operations for all periods presented (see Note 8 – Discontinued Operations for further details).

In May 2014, the FASB issued an update ("ASU 2014-09") establishing ASC Topic 606, Revenue from Contracts with Customers. 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. ASU 2014-09 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2017. We are currently evaluating the impact of the adoption of ASU 2014-09 on our consolidated financial statements.

In June 2014, the FASB issued an update (“ASU 2014-12”) to ASC Topic 718, Compensation – Stock Compensation. 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 begin after December 15, 2015. We are currently evaluating the impact of the adoption of ASU 2014-12 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 beginning after December 15, 2015. We are currently evaluating the impact of the adoption of ASU 2015-02 on our consolidated financial statements.

In April 2015, the FASB issued an update (“ASU 2015-03”) Simplifying the Presentation of Debt Issuance Costs to ASC Topic 835, Interest. ASU 2015-03 requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability to which they relate, consistent with debt discounts, as opposed to being presented as assets. ASU 2015-03 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2015. The adoption of this update on January 1, 2016 will not have a material impact on our consolidated financial statements.

Real Estate Fund [Abstract]

Vornado Capital Partners Real Estate Fund (the "Fund")

5. Real Estate Fund Investments

We are the general partner and investment manager of Vornado Capital Partners Real Estate Fund (the “Fund”), which has an eight-year term and a three-year investment period that ended in July 2013. During the investment period, the Fund was our exclusive investment vehicle for all investments that fit within its investment parameters, as defined. 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.

On January 20, 2015, we and one of the Fund's limited partners co-invested with the Fund to buy out the Fund's joint venture partner's 57% interest in the Crowne Plaza Times Square Hotel (the “Co-Investment”). The purchase price for the 57% interest was approximately $95,000,000 (our share $39,000,000) which valued the property at approximately $480,000,000. The property is encumbered by a $310,000,000 mortgage loan bearing interest at LIBOR plus 2.80% which matures in December 2018 with a one-year extension option. Our aggregate ownership interest in the property increased to 33% from 11%. The Co-Investment is also accounted for under ASC 946 and is included as a component of “real estate fund investments” on our consolidated balance sheet.

On March 25, 2015, the Fund completed the sale of 520 Broadway in Santa Monica, CA for $91,650,000. The Fund realized a $24,705,000 net gain over the holding period.

At June 30, 2015, we had six real estate fund investments with an aggregate fair value of $565,976,000, or $193,164,000 in excess of cost, and had remaining unfunded commitments of $102,324,000, of which our share was $25,581,000. Below is a summary of income from the Fund and the Co-Investment for the three and six months ended June 30, 2015 and 2014.

Toys “R” Us (“Toys”)

As of June 30, 2015, we own 32.5% of Toys. We have not guaranteed any of Toys' obligations and are not committed to provide any support to Toys. Pursuant to ASC 323-10-35-20, we discontinued applying the equity method for our Toys' investment when the carrying amount was reduced to zero in the third quarter of 2014. We will resume application of the equity method if, during the period the equity method has been suspended, our share of unrecognized net income exceeds our share of unrecognized net losses.

In the first quarter of 2014, we recognized our share of Toys' fourth quarter net income of $75,196,000 and a corresponding non-cash impairment loss of the same amount.

Below is a summary of Toys' latest available financial information on a purchase accounting basis:

(1)	At June 30, 2015, the carrying amount of our investment in Toys is less than our share of Toys' equity by approximately $234,553. This basis difference results primarily from non-cash impairment losses aggregating $355,953 that we have recognized through June 30, 2015. We have allocated the basis difference primarily to Toys' real estate.

Alexander's, Inc. (“Alexander's”) (NYSE: ALX)

As of June 30, 2015, we own 1,654,068 Alexander's common shares, or approximately 32.4% of Alexander's common equity. We manage, lease and develop Alexander's properties pursuant to agreements which expire in March of each year and are automatically renewable.

As of June 30, 2015, the market value (“fair value” pursuant to ASC 820, Fair Value Measurements and Disclosures) of our investment in Alexander's, based on Alexander's June 30, 2015 closing share price of $410.00, was $678,168,000, or $547,529,000 in excess of the carrying amount on our consolidated balance sheet. As of June 30, 2015, the carrying amount of our investment in Alexander's exceeds our share of the equity in the net assets of Alexander's by approximately $40,690,000. 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.

We are providing transition services to UE for an initial period of up to two years, including information technology, human resources, tax and financial reporting. UE is providing us with leasing and property management services for (i) the Monmouth Mall, (ii) certain small retail properties that we plan to sell, and (iii) our affiliate, Alexander's, Rego Park retail assets.

Pennsylvania Real Estate Investment Trust (“PREIT”) (NYSE: PEI)

On March 31, 2015, we transferred the redeveloped Springfield Town Center, a 1,350,000 square foot mall located in Springfield, Fairfax County, Virginia, to PREIT Associates, L.P., which is the operating partnership of PREIT, in exchange for $485,313,000; comprised of $340,000,000 of cash and 6,250,000 PREIT operating partnership units (valued at $145,313,000 or $23.25 per PREIT unit) (See Note 8 – Discontinued Operations). $19,000,000 of tenant improvements and allowances was credited to PREIT as a closing adjustment.

On January 1, 2015, we redeemed all of the $500,000,000 principal amount of our outstanding 4.25% senior unsecured notes, which were scheduled to mature on April 1, 2015, at a redemption price of 100% of the principal amount plus accrued interest through December 31, 2014.

On April 1, 2015, we completed a $308,000,000 refinancing of RiverHouse Apartments, a three building, 1,670 unit rental complex located in Arlington, VA. The loan is interest-only at LIBOR plus 1.28% and matures in 2025. We realized net proceeds of approximately $43,000,000. The property was previously encumbered by a 5.43%, $195,000,000 mortgage maturing in April 2015 and a $64,000,000 mortgage at LIBOR plus 1.53% maturing in 2018.

On June 2, 2015, we completed a $205,000,000 financing in connection with the acquisition of 150 West 34th Street (see Note 4 – Acquisitions). The loan bears interest at LIBOR plus 2.25% and matures in 2018 with two one-year extension options.

11. Redeemable Noncontrolling Interests

Redeemable noncontrolling interests on our consolidated balance sheets are comprised primarily of Class A Operating Partnership units that are 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.

Balance at June 30, 2015	$	1,092,894

As of June 30, 2015 and December 31, 2014, the aggregate redemption value of redeemable Class A units was $1,087,466,000 and $1,336,780,000, respectively.

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 $55,097,000 as of June 30, 2015 and December 31, 2014. Changes in the value from period to period, if any, are charged to “interest and debt expense” on our consolidated statements of income.

13. Variable Interest Entities (“VIEs”)

At June 30, 2015 and December 31, 2014, we have unconsolidated VIEs comprised of our investments in the entities that own One Park Avenue, Independence Plaza, the Warner Building and Suffolk Downs. 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. As of June 30, 2015 and December 31, 2014, the net carrying amounts of our investment in these entities were $305,865,000 and $286,783,000, respectively, and our maximum exposure to loss in these entities is limited to our investment. We did not have any consolidated VIEs as of June 30, 2015 and December 31, 2014.

Fair Value Disclosures [Abstract]

Fair Value Measurements

14. Fair Value Measurements

ASC 820, Fair Value Measurements 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) mandatorily redeemable instruments (Series G-1 through G-4 convertible preferred units and Series D-13 cumulative redeemable preferred units), and (v) an interest rate swap. The tables below aggregate the fair values of these financial assets and liabilities by their levels in the fair value hierarchy at June 30, 2015 and December 31, 2014, respectively.

Real Estate Fund Investments

At June 30, 2015, we had six real estate fund investments with an aggregate fair value of $565,976,000, or $193,164,000 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 0.2 to 5.5 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 real estate fund investments at June 30, 2015 and December 31, 2014.

				Weighted Average
		Range		(based on fair value of investments)
Unobservable Quantitative Input		June 30, 2015	December 31, 2014	June 30, 2015	December 31, 2014
	Discount rates	12.0% to 14.5%	12.0% to 17.5%	13.4%	13.7%
	Terminal capitalization rates	4.8% to 6.5%	4.7% to 6.5%	5.5%	5.3%

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 real estate fund investments that are classified as Level 3, for the three and six months ended June 30, 2015 and 2014.

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.

The table below summarizes the changes in the fair value of deferred compensation plan assets that are classified as Level 3, for the three and six months ended June 30, 2015 and 2014.

Fair Value Measurements on a Nonrecurring Basis

Assets measured at fair value on a nonrecurring basis on our consolidated balance sheets consist primarily of real estate assets required to be measured for impairment at December 31, 2014. There are no assets remaining at fair value on a nonrecurring basis at June 30, 2015. The fair values of real estate assets required to be measured for impairment were 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.

(Amounts in thousands)	As of December 31, 2014

Real estate assets	$	4,848	$	-	$	-	$	4,848

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), 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 and borrowings under our revolving credit facility is classified as Level 1, and the fair value of our mortgage and mezzanine loans receivable as of December 31, 2014 is classified as Level 3. There are no mortgage and mezzanine loans receivable outstanding as of June 30, 2015. The fair value of our secured and unsecured debt are classified as Level 2. The table below summarizes the carrying amounts and fair value of these financial instruments as of June 30, 2015 and December 31, 2014.

20. Commitments and Contingencies

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 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 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 $2,480,000 and 15% of the balance of a covered loss (16% effective January 1, 2016) and the Federal government is responsible for the remaining 85% of a covered loss (84% effective January 1, 2016). 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 June 30, 2015, the aggregate dollar amount of these guarantees and master leases is approximately $369,000,000.

At June 30, 2015, $39,382,000 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 June 30, 2015, we expect to fund additional capital to certain of our partially owned entities aggregating approximately $81,000,000.

100 West 33rd Street

On July 28, 2015, we completed a $580,000,000 refinancing of 100 West 33rd Street, a 1.1 million square foot property comprised of 851,000 square feet of office space and the 256,000 square foot Manhattan Mall. The loan is interest only at LIBOR plus 1.65%, and matures in July 2020. We realized net proceeds of approximately $242,000,000.

260 Eleventh Avenue

On July 31, 2015, we acquired 260 Eleventh Avenue, a 235,000 square foot office property leased to the City of New York through 2021 with two five-year renewal options, a 10,000 square foot parking lot and additional air rights. The 44,000 square foot site is located on Eleventh Avenue from 26th to 27th Streets directly across from the Starrett Lehigh building. The transaction is structured as a 99-year ground lease with an option to purchase the land for $110,000,000. The $3,900,000 annual ground rent and the purchase option price escalate annually at the lesser of 1.5% or CPI. The buildings were purchased for 813,900 newly issued Vornado Operating Partnership units valued at approximately $80,000,000. We intend to redevelop and expand the property to serve the supply constrained West Chelsea office market.

Segment Information

21. Segment Information

As a result of the spin-off of substantially all of our Retail Properties segment (see Note 8 – Discontinued Operations), the remaining retail properties no longer meet the criteria to be a separate reportable segment. In addition, as a result of our investment in Toys being reduced to zero, we suspended equity method accounting for our investment in Toys (see Note 7 - Investments in Partially Owned Entities) and the Toys segment no longer meets the criteria to be a separate reportable segment. Accordingly, effective January 1, 2015, the Retail Properties segment and Toys have been reclassified to the Other segment. We have also reclassified the prior period segment financial results to conform to the current period presentation. Below is a summary of net income and a reconciliation of net income to EBITDA(1) by segment for the three and six months ended June 30, 2015 and 2014.

21. Segment Information – continued


	Notes to preceding tabular information:


(1)	EBITDA represents "Earnings Before Interest, Taxes, Depreciation and Amortization." We consider EBITDA a supplemental 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 and Significant Accounting Policies (Policy)	6 Months Ended
	Jun. 30, 2015
Basis of Presentation and Significant Accounting Policies [Abstract]
Basis of Presentation Policy	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 intercompany 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 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, 2014, as filed 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, 2015 are not necessarily indicative of the operating results for the full year. Certain prior year balances have been reclassified in order to conform to the current period presentation. Beginning in the three months ended March 31, 2015, the Company classifies signage revenue within “property rentals”. For the three and six months ended June 30, 2014, $8,873,000 and $18,191,000, respectively, related to signage revenue has been reclassified from “fee and other income” to “property rentals” to conform to the current period presentation.
Real Estate [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.
Revenue Recognition [Policy Text Block]	Condominium Units Held For Sale: Pursuant to ASC 605-35-25-88, Revenue Recognition: Completed Contract Method, revenue from condominium unit sales is recognized upon closing of the sale, as all conditions for full profit recognition have not been met until that time. We use the relative sales value method to allocate costs to individual condominium units.
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 our shareholders 100% of our taxable income and therefore, no provision for Federal income taxes is required. 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. At June 30, 2015 and December 31, 2014, our taxable REIT subsidiaries had deferred tax assets of $95,419,000 and $94,100,000, respectively, which are included in “other assets” on our consolidated balance sheets. Prior to the quarter ended June 30, 2015, there was a full valuation allowance against our deferred tax assets because we had not determined that it is more-likely-than-not that we would use the net operating loss carryforwards to offset future taxable income. During the second quarter of 2015, we began to enter into agreements to sell residential condominium units at 220 CPS and as of June 30, 2015, we had entered into agreements to sell approximately 40% of the project for aggregate sales proceeds of $1.4 billion. Based on these agreements, among other factors, we have concluded that it is more-likely-than-not that we will generate sufficient taxable income to realize the deferred tax assets. Accordingly, during the second quarter of 2015, we reversed $90,030,000 of the allowance for deferred tax assets and recognized an income tax benefit in our consolidated statements of income in the three and six months ended June 30, 2015.
Redeemable Noncontrolling Interests Policy [Text Block]	Redeemable noncontrolling interests on our consolidated balance sheets are comprised primarily of Class A Operating Partnership units that are 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 [Policy Text Block]	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) mandatorily redeemable instruments (Series G-1 through G-4 convertible preferred units and Series D-13 cumulative redeemable preferred units), and (v) an interest rate swap. Fair Value Measurements on a Nonrecurring Basis Assets measured at fair value on a nonrecurring basis on our consolidated balance sheets consist primarily of real estate assets required to be measured for impairment at December 31, 2014. There are no assets remaining at fair value on a nonrecurring basis at June 30, 2015. The fair values of real estate assets required to be measured for impairment were 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. 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), 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 and borrowings under our revolving credit facility is classified as Level 1, and the fair value of our mortgage and mezzanine loans receivable as of December 31, 2014 is classified as Level 3. There are no mortgage and mezzanine loans receivable outstanding as of June 30, 2015. The fair value of our secured and unsecured debt are classified as Level 2.

- Definition

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.

	Notes to preceding tabular information:


(1)	EBITDA represents "Earnings Before Interest, Taxes, Depreciation and Amortization." We consider EBITDA a supplemental 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.

	(a)	As a result of our investment being reduced to zero, we suspended equity method accounting in the third quarter of 2014 (see Note 7 - Investments in Partially Owned Entities). The six months ended June 30, 2014 includes an impairment loss of $75,196.
	(b)	The amounts in these captions (for this table only) exclude income/expense from the mark-to-market of our deferred compensation plan of $609 and $2,380 for the three months ended June 30, 2015 and 2014, respectively, and $2,250 and $6,780 for the six months ended June 30, 2015 and 2014, respectively.
	(c)	The six months ended June 30, 2015 includes $8,817 from the acceleration of the recognition of compensation expense related to 2013-2015 Out-Performance Plans due to the modification of the vesting criteria of awards such that they will fully vest at age 65. The accelerated expense will result in lower general and administrative expense for the remainder of 2015 of $1,734 and $6,217 thereafter.
	(d)	The three months ended June 30, 2015 and 2014, include $327 and $3,016, respectively, and the six months ended June 30, 2015 and 2014, include $22,972 and $3,515, respectively, of transaction costs related to the spin-off of our strip shopping centers and malls (see Note 1 - Organization).
