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 93.6% of the common limited partnership interest in, the Operating Partnership as of June 30, 2017. All references to the “Company,” “we,” “us,” and “our” mean collectively Vornado, the Operating Partnership and those entities/subsidiaries consolidated by Vornado.

On July 17, 2017, we completed the spin-off of our Washington, DC segment comprised of (i) 37 office properties totaling over 11.1 million square feet, five multifamily properties with 3,133 units and five other assets totaling approximately 406,000 square feet and (ii) 18 future development assets totaling over 10.4 million square feet of estimated potential development density, and $275.0 million of cash to JBG SMITH Properties (“JBGS”). On July 18, 2017, JBGS was combined with the management business and certain Washington, DC assets of The JBG Companies (“JBG”), a Washington, DC real estate company. Steven Roth, the Chairman of the Board of Trustees and Chief Executive Officer of Vornado, is the Chairman of the Board of Trustees of JBGS. Mitchell Schear, former President of our Washington, DC business, is a member of the Board of Trustees of JBGS. We are providing transition services to JBGS initially including information technology, financial reporting and payroll services. The spin-off was effected through a tax-free distribution by Vornado to the holders of Vornado common shares of all of the common shares of JBGS at the rate of one JBGS common share for every two common shares of Vornado and the distribution by the Operating Partnership to the holders of its common units of all of the outstanding common units of JBG SMITH Properties LP (“JBGSLP”) at the rate of one JBGSLP common unit for every two common units of VRLP held of record. See JBGS’ Amendment No. 3 on Form 10 (File No. 001-37994) filed with the Securities and Exchange Commission on June 9, 2017 for additional information. Beginning in the third quarter of 2017, the historical financial results of our Washington, DC segment will be 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 the Operating Partnership and their consolidated subsidiaries. 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, 2016, 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, 2017 are not necessarily indicative of the operating results for the full year.

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, as amended by subsequent ASUs on the topic, 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. This standard, which is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2017, requires an entity to recognize revenue to depict the transfer of 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. When adopting this standard, we are permitted to use either the full retrospective method or the modified retrospective method. We will adopt this standard effective as of January 1, 2018 and currently expect to utilize the modified retrospective method of adoption. We have progressed with our project plan for adopting this standard, including gathering and evaluating the inventory of our revenue streams. We expect this standard will have an impact on the presentation of certain lease and non-lease components of revenue from leases upon the adoption of the update (“ASU 2016-02”) Leases with no impact on “total revenues.” We expect this standard will have an impact on the timing of gains on certain sales of real estate. We are continuing to evaluate the impact of this standard on our consolidated financial statements.

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. ASU 2016-01 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. While the adoption of this standard requires us to continue to measure “marketable securities” at fair value at each reporting date, the changes in fair value will be recognized in current period earnings as opposed to “other comprehensive income.”

In February 2016, the FASB issued an update ASU 2016-02 establishing ASC Topic 842, 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 accounted 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. ASU 2016-02 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the overall impact of the adoption of ASU 2016-02 on our consolidated financial statements, including the timing of adopting this standard. ASU 2016-02 will more significantly impact the accounting for leases in which we are a lessee. We have a number of ground leases for which we will be required to record a right-of-use asset and lease liability equal to the present value of the remaining minimum lease payments upon adoption of this standard. We also expect that this standard will have an impact on the presentation of certain lease and non-lease components of revenue from leases with no impact on “total revenues.” In particular, items such as reimbursable real estate taxes and insurance expenses, will be presented in “property rentals” and non-lease components, such as certain reimbursable operating expenses, will be presented in “tenant expense reimbursements” on our consolidated statements of income.

In March 2016, the FASB issued an update (“ASU 2016-09”) Improvements to Employee Share-Based Payment Accounting to ASC Topic 718, Compensation – Stock Compensation (“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, 2016. The adoption of this update as of January 1, 2017, did not have a material impact on our consolidated financial statements.

In August 2016, the FASB issued an update (“ASU 2016-15”) Classification of Certain Cash Receipts and Cash Payments to ASC Topic 230, Statement of Cash Flows. ASU 2016-15 clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows to reduce diversity in practice with respect to (i) debt prepayment or debt extinguishment costs, (ii) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, (iii) contingent consideration payments made after a business combination, (iv) proceeds from the settlement of insurance claims, (v) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, (vi) distributions received from equity method investees, (vii) beneficial interests in securitization transactions, and (viii) separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017, with early adoption permitted. We elected to early adopt ASU 2016-15 effective January 1, 2017, with retrospective application to our consolidated statements of cash flows. The adoption of ASU 2016-15 impacted our classification of distributions received from equity method investees. We selected the nature of earnings approach for classifying distributions. Under this approach, the distributions from equity method investees are classified on the basis of the nature of the activity of the investee that generated the distribution. The retrospective application of ASU 2016-15 resulted in the reclassification of certain distributions of income from partially owned entities to distributions of capital from partially owned entities, which reduced net cash provided by operating activities and net cash used in investing activities by $4,488,000 for the six months ended June 30, 2016.

In November 2016, the FASB issued an update (“ASU 2016-18”) Restricted Cash to ASC Topic 230, Statement of Cash Flows. ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Restricted cash and restricted cash equivalents will be included with cash and cash equivalents when reconciling the beginning of period and end of period balances on the statement of cash flows upon adoption of this standard. ASU 2016-18 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017, with early adoption permitted. We elected to early adopt ASU 2016-18 effective January 1, 2017, with retrospective application to our consolidated statements of cash flows. Accordingly, the consolidated statements of cash flows present a reconciliation of the changes in cash and cash equivalents and restricted cash. Restricted cash primarily 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.

In February 2017, the FASB issued an update (“ASU 2017-05”) Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets to ASC Subtopic 610-20, Other Income–Gains and Losses from the Derecognition of Nonfinancial Assets. ASU 2017-05 clarifies the scope of recently established guidance on nonfinancial asset derecognition as well as the accounting for partial sales of nonfinancial assets. This update conforms the derecognition guidance on nonfinancial assets with the model for transactions in ASC 606. ASU 2017-05 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. We expect to utilize the modified retrospective method of adoption. The adoption of this standard is not expected to have an impact on our consolidated financial statements.

In May 2017, the FASB issued an update (“ASU 2017-09”) Scope of Modification Accounting to ASC 718. ASU 2017-09 provides guidance about which changes to the terms and conditions of a share-based payment award require an entity to apply modification accounting in ASC 718. ASU 2017-09 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. The adoption of this standard is not expected to have an impact on our consolidated financial statements.

We are the general partner and investment manager of Vornado Capital Partners Real Estate Fund (the “Fund”) and own a 25.0% interest in the Fund, which has an eight-year term and a three-year investment period that ended in July 2013. 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.

We are also the general partner and investment manager of the Crowne Plaza Times Square Hotel Joint Venture (the “Crowne Plaza Joint Venture”) and own a 57.1% interest in the joint venture which owns the 24.7% interest in the Crowne Plaza Times Square Hotel not owned by the Fund. The Crowne Plaza Joint Venture is also accounted for under ASC 946 and we consolidate the accounts of the joint venture into our consolidated financial statements, retaining the fair value basis of accounting.

As of June 30, 2017, we had six real estate fund investments through the Fund and the Crowne Plaza Joint Venture with an aggregate fair value of $455,692,000, or $143,092,000 in excess of cost, and had remaining unfunded commitments of $117,902,000, of which our share was $34,519,000.

Equity Method Investments and Joint Ventures [Abstract]

Investments in Partially Owned Entities

6. Investments in Partially Owned Entities

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

As of June 30, 2017, we own 1,654,068 Alexander’s common shares, representing a 32.4% interest in Alexander’s. We account for our investment in Alexander’s under the equity method. 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, 2017, the market value (“fair value” pursuant to ASC Topic 820, Fair Value Measurements (“ASC 820”)) of our investment in Alexander’s, based on Alexander’s June 30, 2017 closing share price of $421.46, was $697,124,000, or $570,494,000 in excess of the carrying amount on our consolidated balance sheet. As of June 30, 2017, 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 $39,468,000. The majority of this basis difference resulted from the excess of our purchase price for the Alexander’s common stock acquired over the book value of Alexander’s net assets. Substantially all of this basis difference was allocated, based on our estimates of the fair values of Alexander’s assets and liabilities, to real estate (land and buildings). We are amortizing the basis difference related to the buildings into earnings as additional depreciation expense over their estimated useful lives. This depreciation is not material to our share of equity in Alexander’s net income. The basis difference related to the land will be recognized upon disposition of our investment.

On June 1, 2017, Alexander’s completed a $500,000,000 refinancing of the office portion of 731 Lexington Avenue. The interest-only loan is at LIBOR plus 0.90% (2.06% at June 30, 2017) and matures in June 2020 with four one-year extension options. In connection therewith, Alexander’s purchased an interest rate cap with a notional amount of $500,000,000 that caps LIBOR at a rate of 6%. The property was previously encumbered by a $300,000,000 interest-only mortgage at LIBOR plus 0.95% which was scheduled to mature in March 2021.

Urban Edge Properties (“UE”) (NYSE: UE)

As of June 30, 2017, we own 5,717,184 UE operating partnership units, representing a 4.8% ownership interest in UE. We account for our investment in UE under the equity method and record our share of UE’s net income or loss on a one-quarter lag basis. In 2017 and 2016, we provided UE with information technology support. UE is providing us with leasing and property management services for (i) certain small retail properties that we plan to sell, and (ii) our affiliate, Alexander’s, Rego Park retail assets. As of June 30, 2017, the fair value of our investment in UE, based on UE’s June 30, 2017 closing share price of $23.73, was $135,669,000, or $93,777,000 in excess of the carrying amount on our consolidated balance sheet.

During the six months ended June 30, 2017, UE issued approximately 14,000,000 operating partnership units related to property acquisitions and a public offering of its common stock. As a result, our ownership interest in UE decreased to 4.8% from 5.4%. In accordance with ASC 323-10-40-1, we account for a unit issuance by an equity method investee as if we had sold a proportionate share of our investment. The average issuance price per unit of the newly issued UE capital is $26.07. Our average per unit carrying amount is $4.55. Accordingly, we recorded a $15,900,000 net gain in connection with this issuance which is included in “income (loss) from partially owned entities” on our consolidated statements of income.

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

As of June 30, 2017, we own 6,250,000 PREIT operating partnership units, representing an 8.0% interest in PREIT. We account for our investment in PREIT under the equity method and record our share of PREIT’s net income or loss on a one-quarter lag basis. As of June 30, 2017, the fair value of our investment in PREIT, based on PREIT’s June 30, 2017 closing share price of $11.32, was $70,750,000, or $46,854,000 below the carrying amount on our consolidated balance sheet. As of June 30, 2017, the carrying amount of our investment in PREIT exceeds our share of the equity in the net assets of PREIT by approximately $84,087,000. The majority of this basis difference resulted from the excess of the fair value of the PREIT operating units received over our share of the book value of PREIT’s net assets. Substantially all of this basis difference was allocated, based on our estimates of the fair values of PREIT’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 PREIT’s net loss. The basis difference related to the land will be recognized upon disposition of our investment.

Farley Post Office Joint Venture

In September 2016, our 50.1% joint venture with the Related Companies (“Related”) was designated by Empire State Development (“ESD”), an entity of New York State to redevelop the historic Farley Post Office building. The building will include a new Moynihan Train Hall and approximately 850,000 rentable square feet of commercial space, comprised of approximately 730,000 square feet of office space and approximately 120,000 square feet of retail space. On June 15, 2017, the joint venture closed a 99-year, triple-net lease with ESD for the commercial space at the Farley Post Office building and made a $230,000,000 upfront contribution, of which our share is $115,230,000, towards the construction of the train hall. The lease calls for annual rent payments of $5,000,000 plus payments in lieu of real estate taxes. Simultaneously, the joint venture completed a $271,000,000 loan facility, with an initial advance of $202,299,000. The interest only loan is at LIBOR plus 3.25% (4.41% at June 30, 2017) and matures in June 2019 with two one-year extension options.

The joint venture has also entered into a development agreement with ESD and a design-build contract with Skanska Moynihan Train Hall Builders. Under the development agreement with ESD, the joint venture is obligated to build the Moynihan Train Hall, with Vornado and Related each guaranteeing the joint venture’s obligations. Under the design-build agreement, Skanska Moynihan Train Hall Builders is obligated to fulfill all of the joint venture’s obligations. The obligations of Skanska Moynihan Train Hall Builders have been bonded by Skanska USA and bears a full guaranty from Skanska AB.

Mezzanine Loan – New York

On May 9, 2017, a $150,000,000 mezzanine loan owned by a joint venture in which we have a 33.3% ownership interest was repaid at its maturity and we received our $50,000,000 share. The mezzanine loan earned interest at LIBOR plus 9.42%.

Sterling Suffolk Racecourse, LLC (“Suffolk Downs JV”)

On May 26, 2017, Suffolk Downs JV, a joint venture in which we have a 21.2% equity interest, sold the property comprising the Suffolk Downs race track in East Boston, Massachusetts (“Suffolk Downs”) for $155,000,000, which resulted in net proceeds and a net gain to us of $15,314,000. In addition, we were repaid $29,318,000 of principal and $6,129,000 of accrued interest on our debt investments in Suffolk Downs JV, resulting in a net gain of $11,373,000.

Redeemable Noncontrolling Interests / Redeemable Partnership Units [Abstract]

Redeemable Noncontrolling Interests / Redeemable Partnership Units

10. Redeemable Noncontrolling Interests/Redeemable Partnership Units

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

Balance as of December 31, 2016	$	1,278,446
Net income		10,935
Other comprehensive loss		(207)
Distributions		(18,078)
Redemption of Class A units for common shares/units, at redemption value		(25,562)
Adjustments to carry redeemable Class A units at redemption value		(90,208)
Other, net		21,758
Balance as of June 30, 2017	$	1,177,084

As of June 30, 2017 and December 31, 2016, the aggregate redemption value of redeemable Class A units of the Operating Partnership, which are those units held by third parties, was $1,171,656,000 and $1,273,018,000, respectively.

Redeemable noncontrolling interests/redeemable partnership units exclude our Series G-1 through G-4 convertible preferred units and Series D-13 cumulative redeemable preferred units, as they are accounted for as liabilities in accordance with ASC 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, 2017 and December 31, 2016. Changes in the value from period to period, if any, are charged to “interest and debt expense” on our consolidated statements of income.

Variable Interest Entities [Abstract]
Variable Interest Entities ("VIEs")	12. Variable Interest Entities (“VIEs”) Unconsolidated VIEs As of June 30, 2017 and December 31, 2016, 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 6 – Investments in Partially Owned Entities). As of June 30, 2017 and December 31, 2016, the net carrying amount of our investments in these entities was $393,418,000 and $392,150,000, respectively, and our maximum exposure to loss in these entities is limited to our investments. Consolidated VIEs Our most significant consolidated VIEs are the Operating Partnership (for Vornado), real estate fund investments, and certain properties that have noncontrolling interests. These entities are VIEs because the noncontrolling interests do not have substantive kick-out or participating rights. We consolidate these entities because we control all of their significant business activities. As of June 30, 2017, the total assets and liabilities of our consolidated VIEs, excluding the Operating Partnership, were $3,648,565,000 and $1,756,632,000, respectively. As of December 31, 2016, the total assets and liabilities of our consolidated VIEs, excluding the Operating Partnership, were $3,638,483,000 and $1,762,322,000, respectively.

Fair Value Disclosures [Abstract]

Fair Value Measurements

13. Fair Value Measurements

ASC 820 defines fair value and establishes a framework for measuring fair value. The objective of fair value is to determine the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). ASC 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 – quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities; Level 2 – observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 – unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as consider counterparty credit risk in our assessment of fair value. Considerable judgment is necessary to interpret Level 2 and 3 inputs in determining the fair value of our financial and non-financial assets and liabilities. Accordingly, our fair value estimates, which are made at the end of each reporting period, may be different than the amounts that may ultimately be realized upon sale or disposition of these assets.

Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

Financial assets and liabilities that are measured at fair value on our consolidated balance sheets consist of (i) marketable securities, (ii) real estate fund investments, (iii) the assets in our deferred compensation plan (for which there is a corresponding liability on our consolidated balance 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 as of June 30, 2017 and December 31, 2016, respectively.

Real Estate Fund Investments

As of June 30, 2017, we had six real estate fund investments with an aggregate fair value of $455,692,000, or $143,092,000 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 0.3 to 3.5 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, current and anticipated market conditions, industry publications and 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, 2017 and December 31, 2016.

			Weighted Average
	Range		(based on fair value of investments)
Unobservable Quantitative Input	June 30, 2017	December 31, 2016	June 30, 2017	December 31, 2016
Discount rates	3.0% to 16.0%	10.0% to 14.9%	11.1%	12.6%
Terminal capitalization rates	4.7% to 5.8%	4.3% to 5.8%	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, 2017 and 2016.

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, 2017 and 2016.

Fair Value Measurements on a Nonrecurring Basis

There were no assets measured at fair value on a nonrecurring basis on our consolidated balance sheets as of June 30, 2017 and December 31, 2016.

Financial Assets and Liabilities not Measured at Fair Value

Financial assets and liabilities that are not measured at fair value on our consolidated balance sheets include cash equivalents (primarily money market funds, which invest in obligations of the United States government), and our secured and unsecured debt. Estimates of the fair value of these instruments are determined by the standard practice of modeling the contractual cash flows required under the instrument and discounting them back to their present value at the appropriate current risk adjusted interest rate, which is provided by a third-party specialist. For floating rate debt, we use forward rates derived from observable market yield curves to project the expected cash flows we would be required to make under the instrument. The fair values of cash equivalents and borrowings under our unsecured revolving credit facilities and unsecured term loan are classified as Level 1. The fair values 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, 2017 and December 31, 2016.

Commitments and Contingencies

19. 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 affected 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”) terrorism events, as defined by the 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 responsible for a deductible of $1,976,000 and 17% of the balance of a covered loss and the Federal government is responsible for the remaining portion of a covered loss. We are ultimately responsible for any loss incurred by PPIC.

We continue to monitor the state of the insurance market and the scope and cost 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 cost 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.

19. Commitments and Contingencies – continued

Other Commitments and Contingencies

We are from time to time involved in legal actions arising in the ordinary course of business. In our opinion, after consultation with legal counsel, the outcome of such matters is not currently expected to have a material adverse effect on our financial position, results of operations or cash flows.

Each of our properties has been subjected to varying degrees of environmental assessment at various times. The environmental assessments did not reveal any material environmental contamination. However, there can be no assurance that the identification of new areas of contamination, changes in the extent or known scope of contamination, the discovery of additional sites or changes in cleanup requirements would not result in significant cost to us.

Generally, 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, 2017, the aggregate dollar amount of these guarantees and master leases is approximately $774,000,000.

As of June 30, 2017, $20,777,000 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 rate coverage and maximum debt to market capitalization ratios, and provide for higher interest rates in the event of a decline in our ratings below Baa3/BBB. Our unsecured revolving credit facilities also contain customary conditions precedent to borrowing, including representations and warranties, and also contain customary events of default that could give rise to accelerated repayment, including such items as failure to pay interest or principal.

As of June 30, 2017, we expect to fund additional capital to certain of our partially owned entities aggregating approximately $52,000,000.

As of June 30, 2017, we have construction commitments aggregating approximately $543,000,000.

Upon completion of the spin-off of our Washington, DC segment, on July 17, 2017, we incurred approximately $47,000,000 of additional transaction costs, primarily for advisory fees which will be recognized as expense in the quarter ended September 30, 2017.

Notes to preceding tabular information:

(1)

EBITDA represents "Earnings Before Interest, Taxes, Depreciation and Amortization." NOI represents "Net Operating Income" (the equivalent of EBITDA on a cash basis). We calculate EBITDA and NOI on an Operating Partnership basis which is before allocation to the noncontrolling interest of the Operating Partnership. We consider EBITDA the primary non-GAAP financial measure for making decisions and assessing the unlevered performance of our segments as it relates to the total return on assets as opposed to the levered return on equity. We also consider NOI a key non-GAAP financial measure. As properties are bought and sold based on a multiple of NOI, we utilize this measure to make investment decisions as well as to compare the performance of our assets to those of our peers. EBITDA and NOI should not be considered substitutes for net income. EBITDA and NOI may not be comparable to similarly titled measures employed by other companies.

Our 7.5% interest in Fashion Centre Mall/Washington Tower and our interest in Rosslyn Plaza (ranging from 43.7% to 50.4%) will not be included in the spin-off of our Washington, DC segment and have been reclassified to Other. The prior year's presentation has been conformed to the current year. In addition, on January 1, 2017, we reclassified our investment in 85 Tenth Avenue from Other to the New York segment as a result of the December 1, 2016 repayment of our loans receivable and the receipt of a 49.9% ownership interest in the property.

(2)

Interest and debt expense, depreciation and amortization and income tax expense (benefit) in the reconciliation of net income (loss) to EBITDA and straight-line rents, amortization of acquired below-market leases, net and other non-cash adjustments in the reconciliation of EBITDA to NOI include our share of these items from partially owned entities.

21. Subsequent Event

330 Madison Avenue

On July 19, 2017, the joint venture, in which we have a 25% interest, completed a $500,000,000 refinancing of 330 Madison Avenue, an 845,000 square foot Manhattan office building. The seven-year interest only loan matures in August 2024 and has a fixed rate of 3.43%. Our share of net proceeds, after repayment of the existing LIBOR plus 1.30% $150,000,000 mortgage and closing costs, was approximately $85,000,000.

Basis of Presentation and Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2017
Basis of Presentation
Basis of Presentation	The accompanying consolidated financial statements are unaudited and include the accounts of Vornado and the Operating Partnership and their consolidated subsidiaries. All inter-company amounts have been eliminated. 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, 2016, 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, 2017 are not necessarily indicative of the operating results for the full year.
Recently Issued Accounting Literature	In February 2017, the FASB issued an update (“ASU 2017-05”) Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets to ASC Subtopic 610-20, Other Income–Gains and Losses from the Derecognition of Nonfinancial Assets. ASU 2017-05 clarifies the scope of recently established guidance on nonfinancial asset derecognition as well as the accounting for partial sales of nonfinancial assets. This update conforms the derecognition guidance on nonfinancial assets with the model for transactions in ASC 606. ASU 2017-05 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. We expect to utilize the modified retrospective method of adoption. The adoption of this standard is not expected to have an impact on our consolidated financial statements.
Real Estate	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. The Crowne Plaza Joint Venture is also accounted for under ASC 946 and we consolidate the accounts of the joint venture into our consolidated financial statements, retaining the fair value basis of accounting.
Cash And Cash Equivalents	In August 2016, the FASB issued an update (“ASU 2016-15”) Classification of Certain Cash Receipts and Cash Payments to ASC Topic 230, Statement of Cash Flows. ASU 2016-15 clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows to reduce diversity in practice with respect to (i) debt prepayment or debt extinguishment costs, (ii) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, (iii) contingent consideration payments made after a business combination, (iv) proceeds from the settlement of insurance claims, (v) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, (vi) distributions received from equity method investees, (vii) beneficial interests in securitization transactions, and (viii) separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017, with early adoption permitted. We elected to early adopt ASU 2016-15 effective January 1, 2017, with retrospective application to our consolidated statements of cash flows. The adoption of ASU 2016-15 impacted our classification of distributions received from equity method investees. We selected the nature of earnings approach for classifying distributions. Under this approach, the distributions from equity method investees are classified on the basis of the nature of the activity of the investee that generated the distribution. The retrospective application of ASU 2016-15 resulted in the reclassification of certain distributions of income from partially owned entities to distributions of capital from partially owned entities, which reduced net cash provided by operating activities and net cash used in investing activities by $4,488,000 for the six months ended June 30, 2016.
Restricted Cash	In November 2016, the FASB issued an update (“ASU 2016-18”) Restricted Cash to ASC Topic 230, Statement of Cash Flows. ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Restricted cash and restricted cash equivalents will be included with cash and cash equivalents when reconciling the beginning of period and end of period balances on the statement of cash flows upon adoption of this standard. ASU 2016-18 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017, with early adoption permitted. We elected to early adopt ASU 2016-18 effective January 1, 2017, with retrospective application to our consolidated statements of cash flows. Accordingly, the consolidated statements of cash flows present a reconciliation of the changes in cash and cash equivalents and restricted cash. Restricted cash primarily 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.
Revenue Recognition	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, as amended by subsequent ASUs on the topic, 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. This standard, which is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2017, requires an entity to recognize revenue to depict the transfer of 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. When adopting this standard, we are permitted to use either the full retrospective method or the modified retrospective method. We will adopt this standard effective as of January 1, 2018 and currently expect to utilize the modified retrospective method of adoption. We have progressed with our project plan for adopting this standard, including gathering and evaluating the inventory of our revenue streams. We expect this standard will have an impact on the presentation of certain lease and non-lease components of revenue from leases upon the adoption of the update (“ASU 2016-02”) Leases with no impact on “total revenues.” We expect this standard will have an impact on the timing of gains on certain sales of real estate. We are continuing to evaluate the impact of this standard on our consolidated financial statements.
Leases	In February 2016, the FASB issued an update ASU 2016-02 establishing ASC Topic 842, 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 accounted 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. ASU 2016-02 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the overall impact of the adoption of ASU 2016-02 on our consolidated financial statements, including the timing of adopting this standard. ASU 2016-02 will more significantly impact the accounting for leases in which we are a lessee. We have a number of ground leases for which we will be required to record a right-of-use asset and lease liability equal to the present value of the remaining minimum lease payments upon adoption of this standard. We also expect that this standard will have an impact on the presentation of certain lease and non-lease components of revenue from leases with no impact on “total revenues.” In particular, items such as reimbursable real estate taxes and insurance expenses, will be presented in “property rentals” and non-lease components, such as certain reimbursable operating expenses, will be presented in “tenant expense reimbursements” on our consolidated statements of income.
Financial Instruments	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. ASU 2016-01 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. While the adoption of this standard requires us to continue to measure “marketable securities” at fair value at each reporting date, the changes in fair value will be recognized in current period earnings as opposed to “other comprehensive income.”
Redeemable Noncontrolling Interests Policy	Redeemable noncontrolling interests on Vornado’s consolidated balance sheets and redeemable partnership units on the consolidated balance sheets of the Operating Partnership are primarily comprised of Class A Operating Partnership units held by third parties and are recorded at the greater of their carrying amount or redemption value at the end of each reporting period. Changes in the value from period to period are charged to “additional capital” in Vornado’s consolidated statements of changes in equity and to “partners’ capital” on the consolidated balance sheets of the Operating Partnership. Redeemable noncontrolling interests/redeemable partnership units exclude our Series G-1 through G-4 convertible preferred units and Series D-13 cumulative redeemable preferred units, as they are accounted for as liabilities in accordance with ASC 480, Distinguishing Liabilities and Equity, because of their possible settlement by issuing a variable number of Vornado common shares.
Fair Value Measurement	ASC 820 defines fair value and establishes a framework for measuring fair value. The objective of fair value is to determine the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). ASC 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 – quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities; Level 2 – observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 – unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as consider counterparty credit risk in our assessment of fair value. Considerable judgment is necessary to interpret Level 2 and 3 inputs in determining the fair value of our financial and non-financial assets and liabilities. Accordingly, our fair value estimates, which are made at the end of each reporting period, may be different than the amounts that may ultimately be realized upon sale or disposition of these assets.
Share Based Compensation Option And Incentive Plans	In March 2016, the FASB issued an update (“ASU 2016-09”) Improvements to Employee Share-Based Payment Accounting to ASC Topic 718, Compensation – Stock Compensation (“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, 2016. The adoption of this update as of January 1, 2017, did not have a material impact on our consolidated financial statements. In May 2017, the FASB issued an update (“ASU 2017-09”) Scope of Modification Accounting to ASC 718. ASU 2017-09 provides guidance about which changes to the terms and conditions of a share-based payment award require an entity to apply modification accounting in ASC 718. ASU 2017-09 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. The adoption of this standard is not expected to have an impact on our consolidated financial statements.

Notes to preceding tabular information:

(1)

EBITDA represents "Earnings Before Interest, Taxes, Depreciation and Amortization." NOI represents "Net Operating Income" (the equivalent of EBITDA on a cash basis). We calculate EBITDA and NOI on an Operating Partnership basis which is before allocation to the noncontrolling interest of the Operating Partnership. We consider EBITDA the primary non-GAAP financial measure for making investment 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. We also consider NOI a key non-GAAP financial measure. As properties are bought and sold based on a multiple of NOI, we utilize this measure to compare the performance of our assets to those of our peers. We also consider NOI a key non-GAAP financial measure. EBITDA and NOI should not be considered substitutes for net income. EBITDA and NOI may not be comparable to similarly titled measures employed by other companies.
