Vornado is the sole general partner of, and owned approximately 93.9% of the common limited partnership interest in the Operating Partnership at March 31, 2014. All references to “we,” “us,” “our,” the “Company” and “Vornado” refer to Vornado Realty Trust and its consolidated subsidiaries, including the Operating Partnership.
	On April 11, 2014, we announced a plan to spin off our shopping center business consisting of 81 strip shopping centers and four malls into a new publicly traded REIT (“SpinCo”). The spin-off is expected to be effectuated through a 1:2 distribution of SpinCo's shares to Vornado common shareholders and Vornado Realty L.P. common unitholders, and is intended to be treated as tax-free for U.S. federal income tax purposes. We intend to file the initial registration statement on Form 10 with the Securities and Exchange Commission (“SEC”) by the end of the second quarter of 2014 and expect the spin-off to be completed by the end of 2014. The transaction is subject to certain conditions, including the SEC declaring that SpinCo's registration statement is effective, filing and approval of SpinCo's listing application, receipt of third party consents, and formal approval and declaration of the distribution by Vornado's Board of Trustees. Vornado may, at any time and for any reason until the proposed transaction is complete, abandon the separation or modify or change its terms.
	Vornado will retain, for disposition in the near term, 20 small retail assets which do not fit SpinCo's strategy, and the Beverly Connection and Springfield Town Center, both of which are under contract for disposition (see Note 8 – Dispositions).

	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, 2013, 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 months ended March 31, 2014 are not necessarily indicative of the operating results for the full year. Certain prior year balances have been reclassified in order to conform to current year presentation.

	In June 2013, the FASB issued an update (“ASU 2013-08”) to ASC Topic 946, Financial Services - Investment Companies (“Topic 946”). ASU 2013-08 amends the guidance in Topic 946 for determining whether an entity qualifies as an investment company and requires certain additional disclosures. ASU 2013-08 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2013. The adoption of this update as of January 1, 2014, did not have any impact on our real estate fund and our consolidated financial statements.
	3. Recently Issued Accounting Literature – continued
	In April 2014, the 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, the ASU 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 begin after December 15, 2014. We are currently evaluating the impact of ASU 2014-08 on our consolidated financial statements.

	In October 2012, we acquired a 25.0% participation in a mortgage and mezzanine loan on 701 Seventh Avenue.  In March 2013, we transferred at par, the 25.0% participation in the mortgage loan to a third party, for $59,375,000 in cash. The transfer did not qualify for sale accounting given our continuing interest in the mezzanine loan. Accordingly, we continued to include the 25.0% participation in the mortgage loan in “mortgage and mezzanine loans receivable” and recorded a $59,375,000 liability in “other liabilities” on our consolidated balance sheet. In January 2014, the mortgage and mezzanine loans were repaid; accordingly, the $59,375,000 asset and liability were eliminated.
	In March 2014, a $30,000,000 mezzanine loan that was scheduled to mature in January 2015 was repaid.
	As of March 31, 2014 and December 31, 2013, the carrying amount of mortgage and mezzanine loans receivable was $42,749,000 and $170,972,000, respectively. These loans have a weighted average interest rate of 8.7% and 11.0% at March 31, 2014 and December 31, 2013, respectively, and have maturities ranging from November 2014 to May 2016.

	Toys “R” Us (“Toys”)
	As of March 31, 2014, we own 32.6% of Toys. We account for our investment in Toys under the equity method and record our share of Toys' net income or loss on a one-quarter lag basis because Toys' fiscal year ends on the Saturday nearest January 31, and our fiscal year ends on December 31. The business of Toys is highly seasonal and substantially all of Toys' net income is generated in its fourth quarter.
	In the fourth quarter of 2013, we wrote down our investment in Toys to its estimated fair value and disclosed that to the extent the fair value of our investment did not change, we would recognize a non-cash impairment loss equal to our share of Toys' fourth quarter net earnings in our first quarter of 2014.
	In the first quarter of 2014, we recognized (i) $1,847,000 of income applicable to Toys, representing management fees earned and received, and (ii) our share of the equity in earnings of Toys' fourth quarter totaling $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:
		(Amounts in thousands)									Balance as of
		Balance Sheet:									1-Feb-14			2-Nov-13

		-1		At March 31, 2014, the carrying amount of our investment in Toys is less than our share of Toys' equity by approximately $349,759. This basis difference results primarily from non-cash impairment losses aggregating $355,953 that we have recognized through March 31, 2014. We have allocated the basis difference primarily to Toys' real estate, which is being amortized over its remaining estimated useful life.

	As of March 31, 2014, 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 March 31, 2014, we have a $42,492,000 receivable from Alexander's for fees under these agreements.
	As of March 31, 2014, the market value (“fair value” pursuant to ASC 820) of our investment in Alexander's, based on Alexander's March 31, 2014 closing share price of $360.99, was $597,102,000, or $429,978,000 in excess of the carrying amount on our consolidated balance sheet. As of March 31, 2014, 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 $41,873,000. 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.

	In January 2013, we and the other equity holders of LNR entered into a definitive agreement to sell LNR for $1.053 billion, of which our share of the net proceeds was $240,474,000. The definitive agreement provided that LNR would not (i) make any cash distributions to the equity holders, including us, through the completion of the sale, which occurred on April 19, 2013, and (ii) take any of the following actions (among others) without the purchaser's approval, the lending or advancing of any money, the acquisition of assets in excess of specified amounts, or the issuance of equity interests. Notwithstanding the terms of the definitive agreement, in accordance with GAAP, we recorded our pro rata share of LNR's earnings on a one-quarter lag basis through the date of sale, which increased the carrying amount of our investment in LNR above our share of the net sales proceeds and resulted in us recognizing a $27,231,000 “other-than-temporary” impairment loss on our investment in the three months ended March 31, 2013.

	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.

	As of March 31, 2014 and December 31, 2013, the aggregate redemption value of redeemable Class A units was $1,139,831,000 and $1,002,620,000, 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 March 31, 2014 and December 31, 2013.

	We do not have any consolidated VIEs. At March 31, 2014 and December 31, 2013, we have unconsolidated VIEs comprised of our investments in the entities that own the Warner Building and Independence Plaza. We do not consolidate these entities because we are not the primary beneficiary and the nature of our involvement in the activities of these entities does not give us power over decisions that significantly affect these entities' economic performance. We account for our investment in these entities under the equity method. As of March 31, 2014 and December 31, 2013, the net carrying amount of our investment in these entities was $148,120,000, and $152,929,000, respectively, and our maximum exposure to loss in these entities is limited to our investment.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	14. Fair Value Measurements
	ASC 820, Fair Value Measurement and Disclosures defines fair value and establishes a framework for measuring fair value. The objective of fair value is to determine the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). ASC 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 – quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities; Level 2 – observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 – unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as consider counterparty credit risk in our assessment of fair value. Considerable judgment is necessary to interpret Level 2 and 3 inputs in determining the fair value of our financial and non-financial assets and liabilities. Accordingly, our fair value estimates, which are made at the end of each reporting period, may be different than the amounts that may ultimately be realized upon sale or disposition of these assets.
	Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis
	Financial assets and liabilities that are measured at fair value on our consolidated balance sheets consist of (i) marketable securities, (ii) Real Estate Fund investments, (iii) the assets in our deferred compensation plan (for which there is a corresponding liability on our consolidated balance sheet), (iv) interest rate swaps and (v) mandatorily redeemable instruments (Series G-1 through G-4 convertible preferred units and Series D-13 cumulative redeemable preferred units). The tables below aggregate the fair values of these financial assets and liabilities by their levels in the fair value hierarchy at March 31, 2014 and December 31, 2013, respectively.

	Real Estate Fund Investments
	At March 31, 2014, our Real Estate Fund had nine investments with an aggregate fair value of $682,002,000, or $167,582,000 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 6.3 years. Cash flows are derived from property rental revenue (base rents plus reimbursements) less operating expenses, real estate taxes and capital and other costs, plus projected sales proceeds in the year of exit. Property rental revenue is based on leases currently in place and our estimates for future leasing activity, which are based on current market rents for similar space plus a projected growth factor. Similarly, estimated operating expenses and real estate taxes are based on amounts incurred in the current period plus a projected growth factor for future periods. Anticipated sales proceeds at the end of an investment's expected holding period are determined based on the net cash flow of the investment in the year of exit, divided by a terminal capitalization rate, less estimated selling costs.
	The fair value of each property is calculated by discounting the future cash flows (including the projected sales proceeds), using an appropriate discount rate and then reduced by the property's outstanding debt, if any, to determine the fair value of the equity in each investment. Significant unobservable quantitative inputs used in determining the fair value of each investment include capitalization rates and discount rates. These rates are based on the location, type and nature of each property, and current and anticipated market conditions, which are derived from original underwriting assumptions, industry publications and from the experience of our Acquisitions and Capital Markets departments. Significant unobservable quantitative inputs in the table below were utilized in determining the fair value of these Fund investments at March 31, 2014.
								Weighted Average
								(based on fair
		Unobservable Quantitative Input				Range		value of investments)
			Discount rates			12.0% to 17.5%		13.90%
			Terminal capitalization rates			5.0% to 6.1%		5.70%
	The above inputs are subject to change based on changes in economic and market conditions and/or changes in use or timing of exit. Changes in discount rates and terminal capitalization rates result in increases or decreases in the fair values of these investments. The discount rates encompass, among other things, uncertainties in the valuation models with respect to terminal capitalization rates and the amount and timing of cash flows. Therefore, a change in the fair value of these investments resulting from a change in the terminal capitalization rate, may be partially offset by a change in the discount rate. It is not possible for us to predict the effect of future economic or market conditions on our estimated fair values.
	The table below summarizes the changes in the fair value of Fund investments that are classified as Level 3, for the three months ended March 31, 2014 and 2013.

	Deferred Compensation Plan Assets
	Deferred compensation plan assets that are classified as Level 3 consist of investments in limited partnerships and investment funds, which are managed by third parties. We receive quarterly financial reports from a third-party administrator, which are compiled from the quarterly reports provided to them from each limited partnership and investment fund. The quarterly reports provide net asset values on a fair value basis which are audited by independent public accounting firms on an annual basis. The third-party administrator does not adjust these values in determining our share of the net assets and we do not adjust these values when reported in our consolidated financial statements.

	Fair Value Measurements on a Nonrecurring Basis
	Assets measured at fair value on a nonrecurring basis on our consolidated balance sheets consist primarily of our investment in Toys “R” Us and real estate assets that were written-down to estimated fair value at March 31, 2014 and December 31, 2013. The fair values of these assets 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. Generally, we consider multiple valuation techniques when measuring fair values but in certain circumstances, a single valuation technique may be appropriate. The tables below aggregate the fair values of these assets by their levels in the fair value hierarchy.

Financial Assets and Liabilities not Measured at Fair Value
Financial assets and liabilities that are not measured at fair value on our consolidated balance sheets include cash equivalents (primarily 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 is classified as Level 3. 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 March 31, 2014 and December 31, 2013.

	15. Incentive Compensation
	Our 2010 Omnibus Share Plan (the “Plan”) provides for grants of incentive and non-qualified stock options, restricted stock, restricted Operating Partnership units and out-performance plan awards to certain of our employees and officers. We account for all stock-based compensation in accordance with ASC 718, Compensation – Stock Compensation. Stock-based compensation expense was $11,024,000 and $7,466,000 in the three months ended March 31, 2014 and 2013, respectively.
	On January 10, 2014, the Compensation Committee approved the 2014 Outperformance Plan, a multi-year, performance-based equity compensation plan and related form of award agreement (the “2014 OPP”). Under the 2014 OPP, participants have the opportunity to earn compensation payable in the form of operating partnership units during a three-year performance measurement period, if and only if we outperform a predetermined total shareholder return (“TSR”) and/or outperform the market with respect to relative TSR. Awards under the 2014 OPP may be earned if we (i) achieve a TSR level greater than 7% per annum, or 21% over the three-year performance measurement period (the “Absolute Component”), and/or (ii) achieve a TSR above that of the SNL US REIT Index (the “Index”) over a three-year performance measurement period (the “Relative Component”). To the extent awards would be earned under the Absolute Component but we underperform the Index, such awards earned under the Absolute Component would be reduced (and potentially fully negated) based on the degree to which we underperform the Index. In certain circumstances, in the event we outperform the Index but awards would not otherwise be earned under the Absolute Component, awards may be increased under the Relative Component. To the extent awards would otherwise be earned under the Relative Component but we fail to achieve at least a 6% per annum absolute TSR, such awards earned under the Relative Component would be reduced based on our absolute TSR, with no awards being earned in the event our TSR during the applicable measurement period is 0% or negative, irrespective of the degree to which we may outperform the Index. If the designated performance objectives are achieved, OPP Units are also subject to time-based vesting requirements. Awards earned under the 2014 OPP vest 33% in year three, 33% in year four and 34% in year five. Dividends on awards earned accrue during the performance measurement period. In addition, our executive officers (for the purposes of Section 16 of the Exchange Act) are required to hold any earned OPP awards (or related equity) for at least one year following vesting.

Coverage for acts of terrorism (excluding NBCR acts) is fully reinsured by third party insurance companies and the federal government with no direct exposure to PPIC. For NBCR acts, PPIC is responsible for a deductible of $2,150,000 and 15% of the balance of a covered loss and the federal government is responsible for the remaining 85% of a covered loss. We are ultimately responsible for any loss incurred by PPIC.
	We continue to monitor the state of the insurance market and the scope and costs of coverage for acts of terrorism. However, we cannot anticipate what coverage will be available on commercially reasonable terms in the future.
	Our debt instruments, consisting of mortgage loans secured by our properties which are non-recourse to us, senior unsecured notes and revolving credit agreements contain customary covenants requiring us to maintain insurance. Although we believe that we have adequate insurance coverage for purposes of these agreements, we may not be able to obtain an equivalent amount of coverage at reasonable costs in the future. Further, if lenders insist on greater coverage than we are able to obtain it could adversely affect our ability to finance our properties and expand our portfolio.
	Other Commitments and Contingencies
	We are from time to time involved in legal actions arising in the ordinary course of business. In our opinion, after consultation with legal counsel, the outcome of such matters is not expected to have a material adverse effect on our financial position, results of operations or cash flows.
	Each of our properties has been subjected to varying degrees of environmental assessment at various times. The environmental assessments did not reveal any material environmental contamination. However, there can be no assurance that the identification of new areas of contamination, changes in the extent or known scope of contamination, the discovery of additional sites, or changes in cleanup requirements would not result in significant costs to us.
	Our mortgage loans are non-recourse to us. However, in certain cases we have provided guarantees or master leased tenant space. These guarantees and master leases terminate either upon the satisfaction of specified circumstances or repayment of the underlying loans. As of March 31, 2014, the aggregate dollar amount of these guarantees and master leases is approximately $420,000,000.
	At March 31, 2014, $38,477,000 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 March 31, 2014, we expect to fund additional capital to certain of our partially owned entities aggregating approximately $125,000,000.

		Notes to preceding tabular information:
	-1	EBITDA represents "Earnings Before Interest, Taxes, Depreciation and Amortization." We consider EBITDA a supplemental measure for making decisions and assessing the unlevered performance of our segments as it relates to the total return on assets as opposed to the levered return on equity. As properties are bought and sold based on a multiple of EBITDA, we utilize this measure to make investment decisions as well as to compare the performance of our assets to that of our peers. EBITDA should not be considered a substitute for net income. EBITDA may not be comparable to similarly titled measures employed by other companies.
	-2	Interest and debt expense, depreciation and amortization and income tax (benefit) expense 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)	3 Months Ended
	Mar. 31, 2014
Basis of Presentation and Significant Accounting Policies [Abstract]	'
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) 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).
	Fair Value Measurements on a Nonrecurring Basis
	Assets measured at fair value on a nonrecurring basis on our consolidated balance sheets consist primarily of our investment in Toys “R” Us and real estate assets that were written-down to estimated fair value at March 31, 2014 and December 31, 2013. The fair values of these assets 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. Generally, we consider multiple valuation techniques when measuring fair values but in certain circumstances, a single valuation technique may be appropriate.
	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 is classified as Level 3. The fair value of our secured and unsecured debt are classified as Level 2.

	See notes on the following page.
		Notes to preceding tabular information:
	-1	EBITDA represents "Earnings Before Interest, Taxes, Depreciation and Amortization." We consider EBITDA a supplemental measure for making decisions and assessing the unlevered performance of our segments as it relates to the total return on assets as opposed to the levered return on equity. As properties are bought and sold based on a multiple of EBITDA, we utilize this measure to make investment decisions as well as to compare the performance of our assets to that of our peers.
