2. Basis of Presentation

The accompanying consolidated financial statements are unaudited and include the accounts of Vornado and its consolidated subsidiaries, including the Operating Partnership. All 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 Securities and Exchange Commission (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, for the year ended December 31, 2012, 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 nine months ended September 30, 2013 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.

Recently Issued Accounting Literature

3. Recently Issued Accounting Literature

In February 2013, the Financial Accounting Standards Board (“FASB”) issued an update (“ASU 2013-02”) to Accounting Standards Codification (“ASC”) Topic 220, Comprehensive Income (“Topic 220”). ASU 2013-02 requires additional disclosures regarding significant reclassifications out of each component of accumulated other comprehensive income, including the effect on the respective line items of net income for amounts that are required to be reclassified into net income in their entirety and cross-references to other disclosures providing additional information for amounts that are not required to be reclassified into net income in their entirety. The adoption of this update as of January 1, 2013, did not have a material impact on our consolidated financial statements, but resulted in additional disclosures (see Note 13 - Accumulated Other Comprehensive Income).

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. We are currently evaluating the impact, if any, of ASU 2013-08 on our real estate fund and our consolidated financial statements.

- Definition

The entire disclosure of changes in accounting principles, including adoption of new accounting pronouncements, that describes the new methods, amount and effects on financial statement line items.

4. Vornado Capital Partners Real Estate Fund (the “Fund”)

We are the general partner and investment manager of our $800,000,000 Fund, to which we committed $200,000,000. The Fund has an eight-year term and a three-year investment period which 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 the AICPA Investment Company Guide 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.

At September 30, 2013, the Fund had nine investments with an aggregate fair value of $635,990,000, or $127,118,000 in excess of cost, and had remaining unfunded commitments of $239,186,000, of which our share was $59,796,000.

5. Mortgage and Mezzanine Loans Receivable

As of September 30, 2013 and December 31, 2012, the carrying amount of mortgage and mezzanine loans receivable was $176,388,000 and $225,359,000, respectively. These loans have a weighted average interest rate of 10.8% and 10.3% at September 30, 2013 and December 31, 2012, respectively, and have maturities ranging from August 2014 to May 2016.

On March 27, 2013, we transferred, at par, a 25% participation in a mortgage loan on 701 Seventh Avenue to a third party for $59,375,000 in cash. We acquired this participation in October 2012, together with a 25% interest in a mezzanine loan on the property. The transfer did not qualify for sale accounting given our continuing interest in the mezzanine loan. Accordingly, we continue to include the 25% participation in the mortgage loan in “Mortgage and Mezzanine Loans Receivable” and have recorded a $59,375,000 liability in “Other Liabilities” on our consolidated balance sheet.

On April 17, 2013, a $50,091,000 mezzanine loan that was scheduled to mature in August 2015, was repaid. In connection therewith, we received net proceeds of $55,358,000, including prepayment penalties, which resulted in income of $5,267,000, included in “interest and other investment (loss) income” on our consolidated statement of income.

Investment in Lexington Realty Trust (“Lexington”) (NYSE: LXP)

From the inception of our investment in Lexington in 2008, until the first quarter of 2013, we accounted for our investment under the equity method because of our ability to exercise significant influence over Lexington's operating and financial policies. As a result of Lexington's common share issuances, our ownership interest has been reduced over time from approximately 17.2% to 8.8% at March 31, 2013. In the first quarter of 2013, we concluded that we no longer have the ability to exercise significant influence over Lexington's operating and financial policies, and began accounting for this investment as a marketable equity security – available for sale, in accordance with ASC Topic 320, Investments – Debt and Equity Securities.

Investment in J.C. Penney Company, Inc. (“J.C. Penney”) (NYSE: JCP)

At December 31, 2012, we owned 23,400,000 J.C. Penney common shares comprised of (i) 18,584,010 common shares at a GAAP cost of $19.71 per share, or $366,291,000 in the aggregate, and (ii) 4,815,990 common shares through a forward contract at a weighted average strike price of $29.34 per share, or $141,309,000 in the aggregate.

On March 4, 2013, we sold 10,000,000 J.C. Penney common shares at a price of $16.03 per share, or $160,300,000 in the aggregate, resulting in a net loss of $36,800,000, which is included in “net gain (loss) on disposition of wholly owned and partially owned assets” on our consolidated statements of income. In addition, in the first quarter of 2013, we wrote down the remaining 8,584,010 J.C. Penney common shares we owned to fair value, based on J.C. Penney's March 31, 2013 closing share price of $15.11 per share, and recorded a $39,487,000 impairment loss, which is included in “interest and other investment (loss) income, net” on our consolidated statements of income.

On September 19, 2013, we settled the forward contract and received 4,815,990 J.C. Penney common shares. In connection therewith, we recognized a $20,012,000 loss from the mark-to-market of the derivative position through its settlement date, which is included in “interest and other investment (loss) income, net” on our consolidated statements of income.

On September 19, 2013, we also sold the remaining 13,400,000 J.C. Penney common shares in a block trade at a price of $13.00 per share, or $174,200,000 in the aggregate and recognized an $18,114,000 net loss, which is included in “net gain (loss) on disposition of wholly owned and partially owned assets” on our consolidated statements of income.

The aggregate economic net loss on our investment in J.C. Penney, from inception through disposition, was $256,156,000.

Other Investments

In the third quarter of 2013, we sold a marketable security for $44,176,000, resulting in a net gain of $31,741,000, which is included in “net gain (loss) on disposition of wholly owned and partially owned assets.”

Toys “R” Us (“Toys”)

As of September 30, 2013, we own 32.6% of Toys. We account for our investment in Toys under the equity method and record our share of Toys' net income or loss on a one-quarter lag basis because Toys' fiscal year ends on the Saturday nearest January 31, and our fiscal year ends on December 31. The business of Toys is highly seasonal. Historically, Toys' fourth quarter net income accounts for more than 80% of its fiscal year net income.

In the fourth quarter of 2012, we recorded a $40,000,000 non-cash impairment loss on our investment in Toys and disclosed, that if current facts don't change, our share of Toys' undistributed income, which in accordance with the equity method of accounting, would increase the carrying amount of our investment above fair value, would require an offsetting impairment loss.

In the first quarter of 2013, we recognized our share of Toys' fourth quarter net income of $78,542,000 and a corresponding non-cash impairment loss of the same amount.

As of September 30, 2013, the carrying amount of our investment in Toys is less than our share of Toys' equity by approximately $145,809,000. This basis difference resulted primarily from the non-cash impairment losses we recognized in 2012 and 2013 aggregating $118,542,000. We have allocated the basis difference to Toys' intangible assets (primarily trade names and trademarks). The basis difference is not being amortized and will be recognized upon disposition of our investment.

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

(Amounts in thousands)						Balance as of
Balance Sheet:						August 3, 2013		October 27, 2012

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

As of September 30, 2013, 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 September 30, 2013, we have a $44,032,000 receivable from Alexander's for fees under these agreements.

As of September 30, 2013, the market value (“fair value” pursuant to ASC 820) of our investment in Alexander's, based on Alexander's September 30, 2013 closing share price of $286.12, was $473,262,000, or $305,644,000 in excess of the carrying amount on our consolidated balance sheet. As of September 30, 2013, the carrying amount of our investment in Alexander's, excluding amounts owed to us, exceeds our share of the equity in the net assets of Alexander's by approximately $42,224,000. 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.

LNR Property LLC (“LNR”)

In the first quarter of 2013, we recognized our 26.2% share of LNR's fourth quarter net income of $18,731,000, which increased the carrying amount of our investment to approximately $241,000,000. On April 22, 2013, LNR was sold for $1.053 billion, and we received net proceeds of $241,000,000 for our interest. Pursuant to the sale agreement, we ceased receiving income as of January 1, 2013.

Independence Plaza

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

(Amounts in thousands)
Land	$	602,662
Building and improvements		252,844
Acquired above-market leases (included in identified intangible assets)		13,115
Acquired in-place leases (included in identified intangible assets)		67,879
Other assets		7,374
Acquired below-market leases (included in deferred revenue)		(99,074)
Purchase price	$	844,800

On June 7, 2013, the existing $323,000,000 mortgage loan was refinanced with a $550,000,000 five-year, fixed-rate interest only mortgage loan bearing interest at 3.48%. The net proceeds of $219,000,000, after repaying the existing loan and closing costs, were distributed to the partners, of which our share was $137,000,000. Simultaneously with the refinancing, we sold an 8.65% economic interest in the Property to our partner for $41,000,000 in cash, which reduced our economic interest to 50.1%. As a result of this transaction, we determined that we were no longer the primary beneficiary of the VIE. Accordingly, we deconsolidated the operations of the Property on June 7, 2013 and began accounting for our investment under the equity method.

650 Madison Avenue

On September 30, 2013, a joint venture, in which we have a 20.1% interest, acquired 650 Madison Avenue, a 27-story, 594,000 square foot Class A office and retail tower located on the full western blockfront of Madison Avenue between 59th and 60th Street, for $1.295 billion. The property contains 523,000 square feet of office space and 71,000 square feet of retail space. The purchase price was funded with cash and a new $800,000,000 seven-year 4.39% interest-only loan. We account for our investment in the joint venture under the equity method.

	(1)	Represents the extended maturity for certain loans in which we have the unilateral right, ability and intent to extend.

	(2)	On February 20, 2013, we completed a $390,000 financing of this property. The 10-year fixed-rate interest only loan bears interest at 3.61%. This property was previously unencumbered.

	(3)	On October 31, 2013, we completed the restructuring of the $678,000 (face amount) 5.74% Skyline properties mortgage loan. The loan has been separated into two tranches; a senior $350,000 position and a junior $328,000 position. The maturity date has been extended from February 2017 to February 2022, with a one-year extension option. The effective interest rate is 2.965%. Capital we invest to re-lease the property will be senior to the $328,000 junior position.

	(4)	On March 25, 2013, we completed a $300,000 financing of this property. The 10-year fixed-rate interest only loan bears interest at 3.56%. The property was previously encumbered by a $282,312 floating-rate loan.

	(5)	On May 13, 2013, we notified the lender that due to tenants vacating, the property's operating cash flow will be insufficient to pay the debt service; accordingly, at our request, the mortgage loan was transferred to the special servicer. We are in discussions with the special servicer to restructure the terms of the loan; there can be no assurance as to the timing and ultimate resolution of these discussions.

Redeemable Noncontrolling Interests [Abstract]

Redeemable Noncontrolling Interests

11. Redeemable Noncontrolling Interests

Redeemable noncontrolling interests on our consolidated balance sheets are primarily comprised of Class A Operating Partnership units held by third parties. Redeemable noncontrolling interests on our consolidated balance sheets 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.

(Amounts in thousands)
Balance at December 31, 2011	$	1,160,677
Net income		40,595
Other comprehensive loss		(15,717)
Distributions		(34,138)
Redemption of Class A units for common shares, at redemption value		(51,216)
Adjustments to carry redeemable Class A units at redemption value		63,657
Redemption of Series D-10 and D-14 redeemable units		(168,300)
Other, net		(59)
Balance at September 30, 2012	$	995,499

Balance at December 31, 2012	$	944,152
Net income		28,960
Other comprehensive income		5,982
Distributions		(25,827)
Redemption of Class A units for common shares, at redemption value		(19,627)
Adjustments to carry redeemable Class A units at redemption value		43,709
Redemption of Series D-15 redeemable units		(36,900)
Other, net		10,649
Balance at September 30, 2013	$	951,098

As of September 30, 2013 and December 31, 2012, the aggregate redemption value of redeemable Class A units was $950,098,000 and $898,152,000, 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 and $55,011,000 as of September 30, 2013 and December 31, 2012, respectively.

On May 9, 2013, we redeemed all of the outstanding 6.875% Series D-15 Cumulative Redeemable Preferred Units with an aggregate face amount of $45,000,000 for $36,900,000 in cash, plus accrued and unpaid distributions through the date of redemption.

Shareholders' Equity

12. Shareholders' Equity

On January 25, 2013, we sold 12,000,000 5.40% Series L Cumulative Redeemable Preferred Shares at a price of $25.00 per share in an underwritten public offering pursuant to an effective registration statement. We retained aggregate net proceeds of $290,536,000, after underwriters' discounts and issuance costs, and contributed the net proceeds to the Operating Partnership in exchange for 12,000,000 Series L Preferred Units (with economic terms that mirror those of the Series L Preferred Shares). Dividends on the Series L Preferred Shares are cumulative and payable quarterly in arrears. The Series L Preferred Shares are not convertible into, or exchangeable for, any of our properties or securities. On or after five years from the date of issuance (or sooner under limited circumstances), we may redeem the Series L Preferred Shares at a redemption price of $25.00 per share, plus accrued and unpaid dividends through the date of redemption. The Series L Preferred Shares have no maturity date and will remain outstanding indefinitely unless redeemed by us.

On February 19, 2013, we redeemed all of the outstanding 6.75% Series F Cumulative Redeemable Preferred Shares and 6.75% Series H Cumulative Redeemable Preferred Shares at par, for an aggregate of $262,500,000 in cash, plus accrued and unpaid dividends through the date of redemption.

Consolidated VIEs

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

Unconsolidated VIEs

At September 30, 2013, we have unconsolidated VIEs comprised of our investments in the entities that own the Warner Building and Independence Plaza. We do not consolidate these entities because we are not the primary beneficiary and the nature of our involvement in the activities of these entities does not give us power over decisions that significantly affect these entities' economic performance. We account for our investment in these entities under the equity method (see Note 7 – Investments in Partially Owned Entities). As of September 30, 2013, the net carrying amount of our investment in these entities was $151,609,000, and at December 31, 2012, the carrying amount of our investment in the Warner Building was $8,775,000. Our maximum exposure to loss in these entities, is limited to our investment.

Fair Value Disclosures [Abstract]

Fair Value Measurements

15. 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 in our consolidated financial statements 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 September 30, 2013 and December 31, 2012, respectively.

Real Estate Fund Investments

At September 30, 2013, our Real Estate Fund had nine investments with an aggregate fair value of $635,990,000, or $127,118,000 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 0.8 to 6.7 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 September 30, 2013.

			Weighted Average
			(based on fair
Unobservable Quantitative Input		Range	value of investments)
	Discount rates	12.0% to 17.5%	13.9%
	Terminal capitalization rates	5.3% to 6.0%	5.7%

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 and nine months ended September 30, 2013 and 2012.

Deferred Compensation Plan Assets

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

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 nine months ended September 30, 2013 and 2012.

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 December 31, 2012. 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 September 30, 2013 and December 31, 2012.

Incentive Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Incentive Compensation

16. 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 rewards to certain of our employees and officers. We account for all stock-based compensation in accordance ASC 718, Compensation – Stock Compensation. Stock-based compensation expense was $9,201,000 and $7,774,000 in the three months ended September 30, 2013 and 2012, respectively and $25,796,000 and $22,821,000 in the nine months ended September 30, 2013 and 2012, respectively.

On March 15, 2013, our Compensation Committee (the “Committee”) approved the 2013 Outperformance Plan, a performance-based equity compensation plan and related form of award agreement (the “2013 OPP”). Under the 2013 OPP, participants have the opportunity to earn compensation payable in the form of operating partnership units in the second and/or third year 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 total TSR. Awards under our 2013 OPP may be earned if (i) we achieve a TSR greater than 14% over the two-year performance measurement period, or 21% over the three-year performance measurement period (the “Absolute Component”), and/or (ii) we achieve a TSR above that of the SNL US REIT Index (the “Index”) over a two-year or three-year performance measurement period (the “Relative Component”). To the extent awards would be earned under the Absolute Component but we underperform the Index, such awards earned would be reduced (and potentially fully negated) based on the degree to which we underperform the Index. In certain circumstances, in the event we outperform the Index but awards would not otherwise be fully earned under the Absolute Component, awards may 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 performance, 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 2013 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 earned OPP awards for one year following vesting.

Dilutive share equivalents may include our Series A convertible preferred shares, employee stock options and restricted stock.

Commitments and Contingencies

21. 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, including coverage for terrorist acts, 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.

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 nuclear, biological, chemical and radiological (“NBCR”) acts, as defined by the Terrorism Risk Insurance Program Reauthorization Act. 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. Coverage for NBCR losses is up to $2.0 billion per occurrence, for which PPIC is responsible for a deductible of $3,200,000 and 15% of the balance of a covered loss and the Federal government is responsible for the remaining 85% of a covered loss. We are ultimately responsible for any losses 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 future policy years.

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 September 30, 2013, the aggregate dollar amount of these guarantees and master leases is approximately $367,000,000.

At September 30, 2013, $33,068,000 of letters of credit were outstanding under one of our revolving credit facilities. Our 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 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.

Two of our wholly owned subsidiaries that are contracted to develop and operate the Cleveland Medical Mart and Convention Center, in Cleveland, Ohio, are required to fund $11,500,000, primarily for tenant improvements, and they are responsible for operating expenses and are entitled to the net operating income, if any, upon the completion of development and the commencement of operations. As of September 30, 2013, our subsidiaries have funded approximately $3,598,000 of the commitment.

As of September 30, 2013, we expect to fund additional capital to certain of our partially owned entities aggregating approximately $155,000,000.

On October 1, 2013, we sold a parcel of land known as Harlem Park located at 1800 Park Avenue (at 125th Street) in New York City for $66,000,000. The sale resulted in net proceeds of approximately $63,000,000 and a net gain of approximately $23,000,000.

On October 4, 2013, we acquired a 92.5% interest in 655 Fifth Avenue, a 57,500 square foot retail and office property located at the northeast corner of Fifth Avenue and 52nd Street in Manhattan with 50 feet of frontage on Fifth Avenue, for $277,500,000 in cash. We consolidate the accounts of the property into our consolidated financial statements.

23. Segment Information

As a result of certain organizational changes and asset sales in 2012, the Merchandise Mart segment no longer meets the criteria to be a separate reportable segment; accordingly, effective January 1, 2013, the remaining assets have been reclassified to “Other.” We have also reclassified the prior period segment financial results to conform to the current year presentation. Below is a summary of net income and a reconciliation of net income to EBITDA(1) by segment for the three and nine months ended September 30, 2013 and 2012.

	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.

Significant Accounting Policies (Policies)	9 Months Ended
Significant Accounting Policies (Policies)	Sep. 30, 2013
Real Estate Fund [Abstract]
Real Estate Fund Accounting [Policy Text Block]	The Fund is accounted for under the AICPA Investment Company Guide 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.
Fair Value Disclosures [Abstract]
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 in our consolidated financial statements 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 December 31, 2012. 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.

	Notes to preceding tabular information (amounts in thousands):

	(1)	Represents the extended maturity for certain loans in which we have the unilateral right, ability and intent to extend.

	(2)	On February 20, 2013, we completed a $390,000 financing of this property. The 10-year fixed-rate interest only loan bears interest at 3.61%. This property was previously unencumbered.

	(3)	On October 31, 2013, we completed the restructuring of the $678,000 (face amount) 5.74% Skyline properties mortgage loan. The loan has been separated into two tranches; a senior $350,000 position and a junior $328,000 position. The maturity date has been extended from February 2017 to February 2022, with a one-year extension option. The effective interest rate is 2.965%. Capital we invest to re-lease the property will be senior to the $328,000 junior position.

	(4)	On March 25, 2013, we completed a $300,000 financing of this property. The 10-year fixed-rate interest only loan bears interest at 3.56%. The property was previously encumbered by a $282,312 floating-rate loan.

	(5)	On May 13, 2013, we notified the lender that due to tenants vacating, the property's operating cash flow will be insufficient to pay the debt service; accordingly, at our request, the mortgage loan was transferred to the special servicer. We are in discussions with the special servicer to restructure the terms of the loan; there can be no assurance as to the timing and ultimate resolution of these discussions.

	(6)	Interest at the Freddie Mac Reference Note Rate plus 1.53%.

	(7)	LIBOR floor of 1.00%.

	(8)	May be redeemed at our option in whole or in part beginning on October 1, 2014, at a price equal to the principal amount plus accrued interest.

	(9)	On March 28, 2013, we extended this revolving credit facility from June 2015 to June 2017, with two six-month extension options. The interest on the extended facility was reduced from LIBOR plus 135 basis points to LIBOR plus 115 basis points. In addition, the facility fee was reduced from 30 basis points to 20 basis points.

- Definition

- Definition

Tabular disclosure of the significant judgments and assumptions made in determining whether a variable interest (as defined) held by the entity requires the variable interest entity (VIE) (as defined) to be consolidated and (or) disclose information about its involvement with the VIE, individually or in aggregate (as applicable); the nature of restrictions, if any, on the consolidated VIE's assets and on the settlement of its liabilities reported by an entity in its statement of financial position, including the carrying amounts of such assets and liabilities; the nature of, and changes in, the risks associated with involvement in the VIE; how involvement with the VIE affects the entity's financial position, financial performance, and cash flows; the lack of recourse if creditors (or beneficial interest holders) of the consolidated VIE have no recourse to the general credit of the primary beneficiary (if applicable); the terms of arrangements, giving consideration to both explicit arrangements and implicit variable interests, if any, that could require the entity to provide financial support to the VIE, including events or circumstances that could expose the entity to a loss; the methodology used by the entity for determining whether or not it is the primary beneficiary of the variable interest entity; the significant factors considered and judgments made in determining that the power to direct the activities of a VIE that most significantly impact the VIE's economic performance are shared (as defined); the carrying amounts and classification of assets and liabilities of the VIE included in the statement of financial position; the entity's maximum exposure to loss, if any, as a result of its involvement with the VIE, including how the maximum exposure is determined and significant sources of the entity's exposure to the VIE; a comparison of the carrying amounts of the assets and liabilities and the entity's maximum exposure to loss; information about any liquidity arrangements, guarantees, and (or) other commitments by third parties that may affect the fair value or risk of the entity's variable interest in the VIE; whether or not the entity has provided financial support or other support (explicitly or implicitly) to the VIE that it was not previously contractually required to provide or whether the entity intends to provide that support, including the type and amount of the support and the primary reasons for providing the support; and supplemental information the entity determines necessary to provide.

	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.

- Definition

Accumulated change in equity from transactions and other events and circumstances from non-owner sources, net of tax effect, at period end. Excludes Net Income (Loss), and accumulated changes in equity from transactions resulting from investments by owners and distributions to owners. Includes foreign currency translation items, certain pension adjustments, unrealized gains and losses on certain investments in debt and equity securities, other than temporary impairment (OTTI) losses related to factors other than credit losses on available-for-sale and held-to-maturity debt securities that an entity does not intend to sell and it is not more likely than not that the entity will be required to sell before recovery of the amortized cost basis, as well as changes in the fair value of derivatives related to the effective portion of a designated cash flow hedge.

- Definition

Securities (including those issuable pursuant to contingent stock agreements) that could potentially dilute basic earnings per share (EPS) or earnings per unit (EPU) in the future that were not included in the computation of diluted EPS or EPU because to do so would increase EPS or EPU amounts or decrease loss per share or unit amounts for the period presented.
