Organization and Formation of Partnership	'
	1. Organization and Formation of Partnership
	First Industrial, L.P. (the "Operating Partnership") was organized as a limited partnership in the state of Delaware on November 23, 1993. The sole general partner is First Industrial Realty Trust, Inc. (the "Company") which owns common units in the Operating Partnership ("Units") representing an approximate 96.0% and 95.5% ownership interest at December 31, 2013 and 2012, respectively. The Company also owns a preferred general partnership interest in the Operating Partnership represented by preferred Units ("Preferred Units") with an aggregate liquidation priority of $75,000 at December 31, 2013. The Company is a real estate investment trust ("REIT") as defined in the Internal Revenue Code of 1986 (the "Code"). The Company’s operations are conducted primarily through the Operating Partnership. The limited partners of the Operating Partnership owned, in the aggregate, approximately a 4.0% and 4.5% interest in the Operating Partnership at December 31, 2013 and 2012, respectively. Operations are also conducted through other partnerships and limited liability companies ("LLCs") of which the Operating Partnership is the sole member, and taxable REIT subsidiaries (together with the Operating Partnership, other partnerships and the LLCs, the "Consolidated Operating Partnership"), the operating data of which is consolidated with that of the Operating Partnership as presented herein. Unless the context otherwise requires, the terms "we," "us" and "our" refer to First Industrial, L.P. and its controlled subsidiaries.
	We also hold at least a 99% limited partnership interest in First Industrial Financing Partnership, L.P. (the "Financing Partnership"), First Industrial Securities, L.P. (the "Securities Partnership"), First Industrial Mortgage Partnership, L.P, (the "Mortgage Partnership"), First Industrial Pennsylvania, L.P. (the "Pennsylvania Partnership"), First Industrial Harrisburg, L.P. (the "Harrisburg Partnership"), First Industrial Indianapolis, L.P. (the "Indianapolis Partnership"), TK-SV, LTD. and FI Development Services, L.P. (together, the "Other Real Estate Partnerships").
	We also own noncontrolling equity interests in, and provide various services to, two joint ventures (the "2003 Net Lease Joint Venture" and the "2007 Europe Joint Venture"; collectively, the "Joint Ventures"). See Note 6 for more information on the Joint Ventures.
	The general partners of the Other Real Estate Partnerships are separate corporations, each with at least a .01% general partnership interest in the Other Real Estate Partnership for which it acts as a general partner. Each general partner of the Other Real Estate Partnerships is a wholly-owned subsidiary of the Company.
	As of December 31, 2013, we owned 587 industrial properties located in 24 states, containing an aggregate of approximately 54.9 million square feet of gross leasable area ("GLA"). On a combined basis, as of December 31, 2013, the Other Real Estate Partnerships owned 65 industrial properties containing an aggregate of approximately 8.1 million square feet of GLA.
	Profits, losses and distributions of us, the LLCs and Other Real Estate Partnerships are allocated to the general partner and the limited partners or the members, as applicable, in accordance with the provisions contained within the partnership agreements, operating agreements or other ownership agreements, as applicable.
	The Other Real Estate Partnerships and the Joint Ventures are accounted for under the equity method of accounting. Accordingly, the operating data of the Other Real Estate Partnerships and the Joint Ventures are not consolidated with that of the Consolidated Operating Partnership as presented herein.
	Any references to the number of buildings and square footage in the financial statement footnotes are unaudited.

Summary of Significant Accounting Policies	'
	3. Summary of Significant Accounting Policies
	In order to conform with generally accepted accounting principles, we are required in preparation of our financial statements to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of December 31, 2013 and 2012, and the reported amounts of revenues and expenses for each of the years ended December 31, 2013, 2012 and 2011. Actual results could differ from those estimates.
	Reclassifications and Other Presentation Matters
	Certain reclassifications have been made to the 2012 Consolidated Balance Sheet to conform to the 2013 presentation. The results of operations for the years ended December 31, 2013 and 2012 includes adjustments to depreciation and amortization expense of $(1,561) and $1,286, respectively, which should have been recorded during previous periods. Management evaluated the impact of the adjustments and does not believe they are material to the results of the current year or any previous period.
	Cash and Cash Equivalents
	Cash and cash equivalents include all cash and liquid investments with an initial maturity of three months or less. The carrying amount approximates fair value due to the short term maturity of these investments.
	Investment in Real Estate and Depreciation
	Investment in real estate is carried at cost, less accumulated depreciation and amortization. We review our properties on a quarterly basis for impairment and provide a provision if impairments exist. To determine if an impairment may exist, we review our properties and identify those that have had either an event of change or event of circumstances warranting further assessment of recoverability (such as a decrease in occupancy or decline in general market conditions). If further assessment of recoverability is needed, we estimate the future net cash flows expected to result from the use of the property and its eventual disposition on an individual property basis. If the sum of the expected future net cash flows (undiscounted and without interest charges) is less than the carrying amount of the property on an individual property basis, we will recognize an impairment loss based upon the estimated fair value of such property. For properties we consider held for sale, we cease depreciating the properties and value the properties at the lower of depreciated cost or fair value, less costs to dispose. If circumstances arise that were previously considered unlikely, and, as a result, we decide not to sell a property previously classified as held for sale, we will reclassify such property as held and used. Such property is measured at the lower of its carrying amount (adjusted for any depreciation and amortization expense that would have been recognized had the property been continuously classified as held and used) or fair value at the date of the subsequent decision not to sell. We classify properties as held for sale when all criteria within the Financial Accounting Standards Board’s (the "FASB") guidance on the impairment or disposal of long-lived assets are met.
	Interest costs, real estate taxes, compensation costs of development personnel and other directly related costs incurred during construction periods are capitalized and depreciated commencing with the date the property is substantially completed. Upon substantial completion, we reclassify construction in progress to building, tenant improvements and leasing commissions. Such costs begin to be capitalized to the development projects from the point we are undergoing necessary activities to get the development ready for its intended use and ceases when the development projects are substantially completed and held available for occupancy.
	Depreciation expense is computed using the straight-line method based on the following useful lives:
		Years
	Buildings and Improvements	7 to 50
	Land Improvements	3 to 20
	Furniture, Fixtures and Equipment	4 to 10
	Tenant Improvements	Shorter of Lease Term or Useful Life
	Construction expenditures for tenant improvements, leasehold improvements and leasing commissions (inclusive of compensation costs of personnel attributable to leasing) are capitalized and amortized over the terms of each specific lease. Capitalized compensation costs of personnel attributable to leasing relate to time directly attributable to originating leases with independent third parties that result directly from and are essential to originating those leases and would not have been incurred had these leasing transactions not occurred. Repairs and maintenance are charged to expense when incurred. Expenditures for improvements are capitalized.
	Upon acquisition of a property, we allocate the purchase price of the property based upon the fair value of the assets acquired and liabilities assumed, which generally consists of land, buildings, tenant improvements, leasing commissions and intangible assets including in-place leases, above market and below market leases and tenant relationships. We allocate the purchase price to the fair value of the tangible assets of an acquired property by valuing the property as if it were vacant. Acquired above and below market leases are valued based on the present value of the difference between prevailing market rates and the in-place rates measured over a period equal to the remaining term of the lease for above market leases and the initial term plus the term of any below market fixed rate renewal options for below market leases. The above market lease values are amortized as a reduction of rental revenue over the remaining term of the respective leases, and the below market lease values are amortized as an increase to base rental revenue over the remaining initial terms plus the terms of any below market fixed rate renewal options of the respective leases.
	The purchase price is further allocated to in-place lease values and tenant relationships based on our evaluation of the specific characteristics of each tenant’s lease and our overall relationship with the respective tenant. The value of in-place lease intangibles and tenant relationships, which are included as components of deferred leasing intangibles, net are amortized over the remaining lease term (and expected renewal periods of the respective lease for tenant relationships) as adjustments to depreciation and other amortization expense. If a tenant terminates its lease early, the unamortized portion of the tenant improvements, leasing commissions, above and below market leases, the in-place lease value and tenant relationships is immediately written off.
	Deferred leasing intangibles, net of accumulated amortization, included in our total assets and total liabilities consist of the following:
		December 31,		December 31,
		2013		2012
	In-Place Leases	$	14,045	$	15,216

	Amortization expense related to in-place leases and tenant relationships, exclusive of amortization expense related to in-place leases and tenant relationships included in discontinued operations, was $5,615, $6,303 and $9,202 for the years ended December 31, 2013, 2012 and 2011, respectively. Rental revenues increased by $465, $666 and $1,340 related to net amortization of above/(below) market leases, exclusive of net amortization related to above/(below) market leases included in discontinued operations, for the years ended December 31, 2013, 2012 and 2011, respectively. We will recognize net amortization related to deferred leasing intangibles over the next five years, for properties owned as of December 31, 2013 as follows:
		Estimated		Estimated Net
		Amortization		Increase to
		of In-Place		Rental Revenues
		Leases and Tenant		Related to

	Foreign Currency Transactions and Translation
	At December 31, 2013, we owned a land parcel located in Toronto, Canada for which the functional currency was determined to be the Canadian dollar. The assets and liabilities related to this land parcel are translated to U.S. dollars from the Canadian dollar based on the current exchange rate prevailing at each balance sheet date. The income statement accounts related to this land parcel are translated using the average exchange rate for the period. The resulting translation adjustments are included in accumulated other comprehensive income.
	Deferred Financing Costs
	Deferred financing costs include fees and costs incurred to obtain long-term financing. These fees and costs are being amortized over the terms of the respective loans. Accumulated amortization of deferred financing costs was $16,520 and $14,551 at December 31, 2013 and 2012, respectively. Unamortized deferred financing costs are written-off when debt is retired before the maturity date.
	Investment in and Advances to Other Real Estate Partnerships
	Investment in and Advances to Other Real Estate Partnerships represents our limited partnership interests in and advances to, through the Operating Partnership, the Other Real Estate Partnerships. We account for our Investment in and Advances to Other Real Estate Partnerships under the equity method of accounting. Under the equity method of accounting, our share of earnings or losses of the Other Real Estate Partnerships is reflected in income as earned and contributions or distributions increase or decrease, respectively, our Investment in and Advances to Other Real Estate Partnerships as paid or received, respectively.
	On a continuous basis, we assess whether there are any indicators that the value of our Investment in and Advances to Other Real Estate Partnerships may be impaired. An investment is impaired if our estimate of the value of the investment is less than the carrying value of the investment, and such decline in value is deemed to be other than temporary. To the extent impairment has occurred, the loss shall be measured as the excess of the carrying amount of the investment over the fair value of the investment. Our estimates of fair value for each investment are based on a number of subjective assumptions that are subject to economic and market uncertainties including, among others, demand for space, market rental rates and operating costs, the discount rate used to value the cash flows of the properties and the discount rate used to value the debt. As these factors are difficult to predict and are subject to future events that may alter our assumptions, our fair values estimated by management in the impairment analyses may not be realized.
	Investments in Joint Ventures
	Investments in joint ventures represent our limited partnership interests in our Joint Ventures. We account for our investments in joint ventures under the equity method of accounting, as we do not have a majority voting interest, operational control or financial control. Control is determined using accounting standards related to the consolidation of joint ventures and variable interest entities. In order to assess whether consolidation of a variable interest entity is required, an enterprise is required to qualitatively assess the determination of the primary beneficiary of a variable interest entity ("VIE") based on whether the entity (1) has the power to direct matters that most significantly impact the activities of the VIE and (2) has the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Additionally, they require an ongoing reconsideration of the primary beneficiary and provide a framework for the events that trigger a reassessment of whether an entity is a VIE.
	Under the equity method of accounting, our share of earnings or losses of our Joint Ventures is reflected in income as earned and contributions or distributions increase or decrease our investments in joint ventures as paid or received, respectively. Differences between our carrying value of our investments in joint ventures and our underlying equity of such Joint Ventures are amortized over the respective lives of the underlying assets.
	On a continuous basis, we assess whether there are any indicators that the value of our investments in joint ventures may be impaired. An investment is impaired if our estimate of the fair value of the investment is less than the carrying value of the investment, and such decline in fair value is deemed to be other than temporary. To the extent impairment has occurred, the loss shall be measured as the excess of the carrying amount of the investment over the fair value of the investment. Our estimates of fair value for each investment are based on a number of subjective assumptions that are subject to economic and market uncertainties including, among others, demand for space, market rental rates and operating costs, the discount rate used to value the cash flows of the properties, the capitalization rate used to estimate the terminal value of the underlying properties and the discount rate used to value the Joint Ventures’ debt. As these factors are difficult to predict and are subject to future events that may alter our assumptions, our fair values estimated in the impairment analyses may not be realized.
	Limited Partners Units
	Limited partner Units are reported within Partners’ Capital in the balance sheet as of December 31, 2013 and 2012 because they are not redeemable for cash or other assets (a) at a fixed or determinable date, (b) at the option of the Unitholder or (c) upon the occurrence of an event that is not solely within the control of the Operating Partnership. Redemption can be effectuated, as determined by the General Partner, either by exchanging the Units for shares of common stock of the Company on a one-for-one basis, subject to adjustment, or by paying cash equal to the fair market value of such shares.
	The Operating Partnership is the only significant asset of the Company and economic, fiduciary and contractual means align the interests of the Company and the Operating Partnership. The Board of Directors and officers of the Company direct the Company to act when acting in its capacity as sole general partner of the Operating Partnership. Because of this, the Operating Partnership is deemed to have effective control of the form of redemption consideration. As of December 31, 2013, all criteria were met for the Operating Partnership to control the actions or events necessary to issue the maximum number of the Company’s common shares required to be delivered upon redemption of all remaining Units.
	Stock Based Compensation
	We measure compensation cost for all stock-based awards at fair value on the date of grant and recognize compensation expense over the service period for awards expected to vest.
	Net income, net of preferred unit distributions and redemption of preferred units, is allocated to Unitholders and participating securities based upon their proportionate share of weighted average Units plus weighted average participating securities. Participating securities are unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents. Restricted stock awards granted to employees and directors are considered participating securities as they receive non-forfeitable dividend or dividend equivalents at the same rate as Units. See Note 11 for further disclosure about participating securities.
	Revenue Recognition
	Rental income is recognized on a straight-line method under which contractual rent increases are recognized evenly over the lease term. Tenant recovery income includes payments from tenants for real estate taxes, insurance and other property operating expenses and is recognized as revenue in the same period the related expenses are incurred by us.
	Revenue is generally recognized on payments received from tenants for early lease terminations upon the effective termination of a tenant’s lease and when we have no further obligations under the lease.
	Interest income on notes receivable is recognized based on the accrual method unless a significant uncertainty of collection exists. If a significant uncertainty exists, interest income is recognized as collected.
	We provide an allowance for doubtful accounts against the portion of tenant accounts receivable including deferred rent receivable, which is estimated to be uncollectible. Accounts receivable in the consolidated balance sheets are shown net of an allowance for doubtful accounts of $1,352 and $1,852 as of December 31, 2013 and 2012, respectively. Deferred rent receivable in the consolidated balance sheets is shown net of an allowance for doubtful accounts of $1,694 and $1,733 as of December 31, 2013 and 2012, respectively. For accounts receivable we deem uncollectible, we use the direct write-off method.
	Gain on Sale of Real Estate
	Gain on sale of real estate is recognized using the full accrual method, when appropriate. Gains relating to transactions which do not meet the full accrual method of accounting are deferred and recognized when the full accrual method of accounting criteria are met or by using the installment or deposit methods of profit recognition, as appropriate in the circumstances. As the assets are sold, their costs and related accumulated depreciation are written off with resulting gains or losses reflected in net income or loss. Estimated future costs to be incurred by us after completion of each sale are included in the determination of the gain on sales.
Notes Receivable
Notes receivable are primarily comprised of mortgage notes receivable that we have made in connection with sales of real estate assets. The notes receivable are recorded at fair value at the time of issuance. Discounts on notes receivable are accreted over the life of the related note receivable. Interest income is accrued as earned. Notes receivable are considered past due when a contractual payment is not remitted in accordance with the terms of the note agreement. On a quarterly basis, we evaluate the collectability of each mortgage note receivable on an individual basis based on various factors which may include payment history, expected fair value of the collateral and internal and external credit information. A loan is considered impaired when, based upon current information and events, it is probable that we will be unable to collect all amounts due under the existing contractual terms. When a loan is considered impaired, the amount of the loss accrual is calculated by comparing the carrying amount of the note receivable to the present value of expected future cash flows. Since the majority of our notes receivable are collateralized by a first mortgage, the loans have risk characteristics similar to the risks in owning commercial real estate.
Income Taxes
In accordance with partnership taxation, each of the partners is responsible for reporting their share of taxable income or loss.
A benefit/provision has been made for federal, state and local income taxes in the accompanying consolidated financial statements. We may also be subject to certain federal excise and franchise taxes if we engage in certain types of transactions. In accordance with FASB’s guidance, the total benefit/provision has been separately allocated to income (loss) from continuing operations, income (loss) from discontinued operations and gain (loss) on sale of real estate. The provision for excise and franchise taxes has been reflected in general and administrative expense in the consolidated statements of operations and has not been separately stated due to its insignificance.
During 2005, we recorded a $745 franchise tax reserve related to a potential state franchise tax assessment for the 1996-2001 tax years. During the year ended December 31, 2011, we received a refund from the state, representing amounts paid during 2006 related to the 1996-2001 tax years. Based on the refund received and discussions with the taxing authorities, as of December 31, 2011, management believes that it is unlikely that any franchise tax amounts will be assessed by the state for such tax years. As such, during the year ended December 31, 2011, we reversed $745 of franchise taxes. Franchise taxes are recorded within general and administrative expense.
Earnings Per Unit ("EPU")
Basic net income (loss) available to Unitholders per Unit is computed by dividing net income (loss) available to Unitholders by the weighted average number of Units outstanding for the period. Diluted net income (loss) available to Unitholders per Unit is computed by dividing net income (loss) available to Unitholders by the sum of the weighted average number of Units outstanding and any dilutive non-participating securities for the period. See Note 11 for further disclosure about EPU.
Derivative Financial Instruments
Historically, we have used interest rate protection agreements ("Agreements") to fix the interest rate on anticipated offerings of senior unsecured notes or convert floating rate debt and preferred units to fixed rate. Receipts or payments that result from the settlement of Agreements used to fix the interest rate on anticipated offerings of senior unsecured notes are amortized over the life of the derivative or the life of the debt and included in interest expense. Receipts or payments resulting from Agreements used to convert floating rate debt to fixed rate debt are recognized as a component of interest expense. Agreements which qualify for hedge accounting are marked-to-market and any gain or loss that is effective is recognized in other comprehensive income (partners’ capital). Agreements which do not qualify for hedge accounting are marked-to-market and any gain or loss is recognized in net income (loss) available to Unitholders immediately. Amounts accumulated in other comprehensive income during the hedge period are reclassified to earnings in the same period during which the forecasted transaction or hedged item affects net income (loss). The credit risks associated with Agreements are controlled through the evaluation and monitoring of the creditworthiness of the counterparty. In the event that the counterparty fails to meet the terms of Agreements, our exposure is limited to the current value of the interest rate differential, not the notional amount, and our carrying value of Agreements on the balance sheet. See Note 16 for more information on the Agreements.
Fair Value of Financial Instruments
Financial instruments other than our derivatives include tenant accounts receivable, notes receivable, accounts payable, other accrued expenses, mortgage loans payable, unsecured credit facility and senior unsecured notes. The fair values of the tenant accounts receivable, accounts payable and other accrued expenses approximate their carrying or contract values. See Note 7 for the fair values of the mortgage loans payable, unsecured credit facility and senior unsecured notes and see Note 4 for the fair value of our notes receivable.
Discontinued Operations
The FASB’s guidance on financial reporting for the disposal of long lived assets requires that the results of operations and gains or losses on the sale of property or property held for sale be presented in discontinued operations if both of the following criteria are met: (a) the operations and cash flows of the property have been (or will be) eliminated from our ongoing operations as a result of the disposal transaction and (b) we will not have any significant continuing involvement in the operations of the property after the disposal transaction. The guidance also requires prior period results of operations for these properties to be reclassified and presented in discontinued operations in prior consolidated statements of operations.
Segment Reporting
Management views the Consolidated Operating Partnership as a single segment based on its method of internal reporting.
Recent Accounting Pronouncements
In February 2013, the FASB issued Accounting Standards Update No. 2013-02, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income" ("ASU 2013-02"). ASU 2013-02 requires that public companies present, either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. ASU 2013-02 is effective for annual periods beginning after December 15, 2012, and is to be applied prospectively. The adoption of this guidance did not have a material impact on our consolidated financial statements.

	Acquisitions
	In 2011, we acquired one industrial property comprising approximately 0.7 million square feet of GLA through the purchase of the 85% equity interest in one property from the institutional investor in the 2003 Net Lease Joint Venture (see Note 6). The gross agreed-upon fair value for the industrial property was $30,625, excluding costs incurred in conjunction with the acquisition of the industrial property. The acquisition was funded through the assumption of a mortgage loan, whose carrying value approximated fair market value, in the amount of $24,417 and a cash payment of $5,277 (85% of the net fair value of the acquisition). We accounted for this transaction as a step acquisition utilizing the purchase method of accounting. Due to the change in control that occurred, we recorded a gain during the year ended December 31, 2011 of $689 related to the difference between our carrying value and fair value of our equity interest on the acquisition date.
	In 2012, we acquired one industrial property comprising approximately 0.4 million square feet of GLA through the purchase of the 85% equity interest in one property from the institutional investor in the 2003 Net Lease Joint Venture (see Note 6) and several land parcels. The gross agreed-upon fair value for the industrial property was $21,819, excluding costs incurred in conjunction with the acquisition of the industrial property. The acquisition was funded through the assumption of a mortgage loan, which was subsequently paid off on the date of acquisition and whose carrying value approximated fair market value, in the amount of $12,026 and a cash payment of $8,324 (85% of the net fair value of the acquisition). We accounted for this transaction as a step acquisition utilizing the purchase method of accounting. Due to the change in control that occurred, we recorded a gain during the year ended December 31, 2012 of $776 related to the difference between our carrying value and fair value of our equity interest on the acquisition date. The purchase price of the land parcels was approximately $40,003, excluding costs incurred in conjunction with the acquisition of the land parcels.
	In 2013, we acquired two industrial properties, one of which we acquired through the acquisition of 100% of the equity interest in the limited liability company that owned the industrial property, comprising approximately 1.1 million square feet of GLA and several land parcels. One of the two industrial properties was vacant upon acquisition. The purchase price of these acquisitions totaled approximately $72,812, excluding costs incurred in conjunction with the acquisition of the industrial properties and land parcels.
	We value third party acquisitions and acquisitions of unconsolidated joint venture partner interests in industrial properties on a similar basis, generally by applying an income capitalization approach. The fair value measurements are based on significant inputs not observable in the market and thus represent Level 3 measurements, as discussed below. The fair value estimates for each industrial property acquired from our joint venture partner during the years ended December 31, 2012 and 2011 were based on a weighted average capitalization rate approximating 7.3% and 8.4%, respectively. The fair value measurements also include consideration of the fair market value of debt.
	Intangible Assets (Liabilities) Subject To Amortization in the Period of Acquisition
	The fair value at the date of acquisition of in-place leases, tenant relationships and below market leases recorded due to the real estate properties acquired for the years ended December 31, 2013 and 2012, which are recorded as deferred leasing intangibles, are as follows:
		Year Ended			Year Ended
		December 31,			December 31,
		2013			2012
	In-Place Leases	$	2,807		$	1,750
	Tenant Relationships	$	1,914		$	1,012
	Below Market Leases	$	(188	)	$	(102	)
	The weighted average life in months of in-place leases, tenant relationships and below market leases recorded at the time of acquisition as a result of the real estate properties acquired for the years ended December 31, 2013 and 2012 is as follows:
		Year Ended		Year Ended
		December 31,		December 31,
		2013		2012
	In-Place Leases	52		118
	Tenant Relationships	112		178
	Below Market Leases	52		118
	Sales and Discontinued Operations
	In 2011, we sold 34 industrial properties comprising approximately 2.9 million square feet of GLA and one land parcel. Gross proceeds from the sales of the industrial properties and one land parcel were approximately $81,693. Included in the 34 industrial properties sold is one industrial property totaling approximately 0.4 million square feet of GLA that we transferred title to a lender in satisfaction of a non-recourse mortgage loan. The gain on sale of real estate was approximately $20,184, of which $18,814 is shown in discontinued operations. The 34 sold industrial properties meet the criteria to be included in discontinued operations. Therefore the results of operations and gain on sale of real estate for the 34 sold industrial properties are included in discontinued operations. The results of operations and gain on sale of real estate for the one land parcel, which does not meet the criteria to be included in discontinued operations, is included in continuing operations.
	In 2012, we sold 26 industrial properties comprising approximately 4.1 million square feet of GLA and one land parcel. Gross proceeds from the sales of the industrial properties and one land parcel were approximately $83,098. The gain on sale of real estate was approximately $16,535, of which $12,758 is shown in discontinued operations. The 26 sold industrial properties meet the criteria to be included in discontinued operations. Therefore the results of operations and gain on sale of real estate for the 26 industrial properties sold are included in discontinued operations. The results of operations and gain on sale of real estate for the one land parcel, which does not meet the criteria to be included in discontinued operations, is included in continuing operations.
	In 2013, we sold 65 industrial properties comprising approximately 2.8 million square feet of GLA and several land parcels. Gross proceeds from the sales of the industrial properties and land parcels were approximately $138,769. The gain on sale of real estate was approximately $33,687, of which $32,657 is shown in discounted operations. The 65 sold industrial properties meet the criteria to be included in discontinued operations. Therefore the results of operations and gain on sale of real estate for the 65 industrial properties sold are included in discontinued operations. The results of operations and gain on sale of real estate for the several land parcels, which do not meet the criteria to be included in discontinued operations, are included in continuing operations.
	The following table discloses certain information regarding the industrial properties included in our discontinued operations for the years ended December 31, 2013, 2012 and 2011:
		Year Ended December 31,
		2013			2012			2011
	Total Revenues	$	10,209		$	20,552		$	30,777
	Property Expenses	(4,133		)	(8,490		)	(12,438		)
	Impairment of Real Estate	(1,605		)	(1,121		)	(6,214		)
	Depreciation and Amortization	(3,494		)	(7,561		)	(8,174		)
	Interest Expense	—			—			(63		)
	Gain on Sale of Real Estate	32,657			12,758			18,814
	Provision for Income Taxes	—			—			(1,246		)
	Income from Discontinued Operations	$	33,634		$	16,138		$	21,456
	At December 31, 2013 and 2012, we had notes receivable and accrued interest outstanding, issued in connection with sales of industrial properties, of approximately $52,605 and $40,771, net of a discount of $191 and $255, respectively, which are included as a component of prepaid expenses and other assets, net. At December 31, 2013 and 2012, the fair value of the notes receivable, including accrued interest, was $53,482 and $44,352, respectively. The fair value of our notes receivable was determined by discounting the future cash flows using the current rates at which similar loans with similar remaining maturities would be made to other borrowers. The current market rates we utilized were internally estimated; therefore, we have concluded that our determination of fair value of our notes receivable was primarily based upon Level 3 inputs, as discussed below.
	Impairment Charges
	During the years ended December 31, 2013, 2012 and 2011, we recorded the following net non-cash impairment charges (reversals):
		Year			Year			Year
		Ended			Ended			Ended
		December 31,			December 31,			December 31,
		2013			2012			2011
	Sold Operating Properties	$	1,605		$	1,121		$	6,214
	Impairment—Discontinued Operations	$	1,605		$	1,121		$	6,214
	Sold Land Parcels	$	—		$	—		$	(5,918	)
	Operating Properties Not Held for Sale	1,047			(20		)	(1,768		)
	Land Parcels	—			—			(607		)
	Impairment—Continuing Operations	$	1,047		$	(20	)	$	(8,293	)
	Total Net Impairment	$	2,652		$	1,101		$	(2,079	)
	The net impairment charges for assets that qualify to be classified as held for sale are calculated as the difference between the carrying value of the properties and land parcels and the estimated fair value, less costs to sell. The impairment charges for assets not held for sale are calculated as the difference between the carrying value of the properties and land parcels and the estimated fair value. The net impairment charges recorded during the years ended December 31, 2013, 2012 and 2011 are due to marketing certain properties and land parcels for sale and our assessment of the likelihood and timing of a potential sale transaction. Catch-up depreciation and amortization has been recorded during the years ended December 31, 2012 and 2011, if applicable, for certain assets that are no longer classified as held for sale.
	The accounting guidance for the fair value measurement provisions for the impairment of long lived assets establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets for identical assets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The real estate assets measured at fair value on a non-recurring basis during the years ended December 31, 2013 and 2012 were either sold or are recorded at carrying value at December 31, 2013.
	The fair market values were determined using widely accepted valuation techniques including discounted cash flow analyses using expected cash flows, internal valuations of real estate and third party offers. For operational real estate assets, the most significant assumptions used in the discounted cash flow analyses included the discount rate, projected occupancy levels, market rental rates, capital expenditures and the terminal capitalization rate. For the valuation of land parcels, we reviewed recent comparable sales transactions, to the extent available, or if not available, we considered older comparable transactions, adjusted upward or downward to reflect management’s assumptions about current market conditions. In all cases, members of our management team that were responsible for the individual markets where the land parcels were located determined the internal valuations. Valuations based on third party offers include bona fide contract prices and letter of intent amounts that we believe are indicative of fair value.

	6. Investments in Joint Ventures
	On May 16, 2003, we entered into the 2003 Net Lease Joint Venture with an institutional investor to invest in industrial properties. We own a 15% equity interest in and provide property management services to the 2003 Net Lease Joint Venture. At December 31, 2013, the 2003 Net Lease Joint Venture owned four industrial properties comprising approximately 2.5 million square feet of GLA. During January 2014, the 2003 Net Lease Joint Venture sold two properties comprising approximately 1.6 million square feet of GLA.
	The 2003 Net Lease Joint Venture is considered a variable interest entity in accordance with the FASB guidance on the consolidation of variable interest entities. We continue to conclude that we are not the primary beneficiary of this venture. As of December 31, 2013, our investment in the 2003 Net Lease Joint Venture is $907. Our maximum exposure to loss is equal to our investment. We acquired the 85% equity interest in one property on February 13, 2012 and the 85% equity interest in another property on May 26, 2011, in each case from the institutional investor in the 2003 Net Lease Joint Venture (see Note 4).
	During December 2007, we entered into the 2007 Europe Joint Venture with an institutional investor to invest in, own, develop, redevelop and operate industrial properties. We continue to hold our 10% equity interest in the 2007 Europe Joint Venture. As of December 31, 2013, the 2007 Europe Joint Venture did not own any properties.
	During the years ended December 31, 2013, 2012 and 2011, we recognized fees of $231, $516 and $970, respectively, from our Joint Ventures.
	The combined summarized financial information of the investments in Joint Ventures is as follows:

	Mortgage Loans Payable, Net
	During the year ended December 31, 2012, we originated the following mortgage loans:
	Mortgage		Loan			Interest		Origination		Maturity	Amortization		Number of	GLA	Properties
	Financing		Principal			Rate		Date		Date	Period		Industrial	(In millions)	Carrying
													Properties		Value at

	I-V		$	97,561		4.03	%	Aug-12		Sep-22	30-year		30	3.7	$	100,443
	For Mortgage Financings I through V, principal prepayments were prohibited for 12 months after loan origination, after which prepayment premiums are calculated at the greater of yield maintenance or 1% of the outstanding balance.
	During the years ended December 31, 2013 and 2012, we paid off and retired prior to maturity mortgage loans payable in the amount of $64,395 and $14,112, respectively. In connection with these pay offs prior to maturity, we recognized $1,364 and $361 as loss from retirement of debt for the years ended December 31, 2013 and 2012, respectively.
	As of December 31, 2013, mortgage loans payable are collateralized, and in some instances cross-collateralized, by industrial properties with a net carrying value of $729,348. We believe the Operating Partnership and the Company were in compliance with all covenants relating to mortgage loans payable as of December 31, 2013.
	Senior Unsecured Notes, Net
	During the years ended December 31, 2013 and 2012, we repurchased and retired the following senior unsecured notes prior to maturity:
		Principal Amount Repurchased						Purchase Price

	Total	$	29,824		$	106,303		$	33,492		$	110,613
	In connection with these repurchases prior to maturity, we recognized $5,003 and $9,323 as loss from retirement of debt for the years ended December 31, 2013 and 2012, which is the difference between the repurchase price and the principal amount retired, net of the pro rata write-off of the unamortized debt issue discount, the unamortized deferred financing costs, the unamortized settlement amount of the interest rate protection agreements and the professional services fees related to the repurchases of $28, $191, $1,116 and $0 and $598, $728, $3,247 and $440, respectively.
	On April 16, 2012, we paid off and retired our 2012 Notes, at maturity, in the amount of $61,829.
	The indentures governing our senior unsecured notes contain certain financial covenants, including limitations on incurrence of debt and debt service coverage. We believe the Operating Partnership and the Company were in compliance with all covenants relating to senior unsecured notes as of December 31, 2013. However, these financial covenants are complex and there can be no assurance that these provisions would not be interpreted by our noteholders in a manner that could impose and cause us to incur material costs.
	Unsecured Credit Facility
	On July 19, 2013, we amended and restated our existing $450,000 revolving credit agreement (the "Old Credit Facility"), increasing the borrowing capacity thereunder to $625,000 (as amended and restated, the "Unsecured Credit Facility"). We may request that the borrowing capacity under the Unsecured Credit Facility be increased to $825,000, subject to certain restrictions. The amendment extended the maturity date from December 12, 2014 to September 29, 2017 with an option to extend an additional one year at our election, subject to certain restrictions. At December 31, 2013, the Unsecured Credit Facility provides for interest only payments at LIBOR plus 150 basis points. The interest rate on the Unsecured Credit Facility varies based on our leverage ratio. In the event we achieve an investment grade rating from one of certain rating agencies, the rate may be decreased at our election, based on the investment grade rating. In connection with the amendment of the Old Credit Facility, we wrote off $56 of unamortized deferred financing costs, which is included in loss from retirement of debt for the year ended December 31, 2013.
	The Unsecured Credit Facility contains certain financial covenants, including limitations on incurrence of debt and debt service coverage. Under the Unsecured Credit Facility, an event of default can also occur if the lenders, in their good faith judgment, determine that a material adverse change has occurred which could prevent timely repayment or materially impair our ability to perform our obligations under the loan agreement. We believe that we were in compliance with all covenants relating to the Unsecured Credit Facility as of December 31, 2013. However, these financial covenants are complex and there can be no assurance that these provisions would not be interpreted by our lenders in a manner that could impose and cause us to incur material costs.
	Indebtedness
	The following is a schedule of the stated maturities and scheduled principal payments of our indebtedness, exclusive of premiums and discounts, for the next five years ending December 31, and thereafter:
		Amount
	2014	$	111,518
	2015	34,726
	2016	266,262
	2017	339,783
	2018	126,951
	Thereafter	320,756
	Total	$	1,199,996
Fair Value
At December 31, 2013 and 2012, the fair value of our indebtedness was as follows:
	December 31, 2013						December 31, 2012
	Carrying			Fair			Carrying			Fair
	Amount			Value			Amount			Value
Mortgage Loans Payable, Net	$	580,215		$	585,449		$	656,329		$	699,903
Senior Unsecured Debt, Net	445,916			482,781			474,150			516,943
Unsecured Credit Facility	173,000			173,000			98,000			98,192
Total	$	1,199,131		$	1,241,230		$	1,228,479		$	1,315,038
The fair values of our mortgage loans payable were determined by discounting the future cash flows using the current rates at which similar loans would be made based upon similar leverage levels and similar remaining maturities. The current market rates we utilized were internally estimated. The fair value of the senior unsecured debt was determined by using rates, as advised by our bankers in certain cases, that are based upon recent trades within the same series of the senior unsecured debt, recent trades for senior unsecured debt with comparable maturities, recent trades for fixed rate unsecured debt from companies with profiles similar to ours, as well as overall economic conditions. The fair value of the Unsecured Credit Facility was determined by discounting the future cash flows using current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining term, assuming no repayment until maturity. We have concluded that our determination of fair value for our mortgage loans payable, senior unsecured debt and Unsecured Credit Facility was primarily based upon Level 3 inputs.

	8. Partners’ Capital
	We have issued general partnership units and limited partnership units and preferred general partnership units. The general partnership units resulted from capital contributions from the Company. The limited partnership units are issued in conjunction with the acquisition of certain properties (see discussion below). Subject to certain lock-up periods, holders of limited partner Units of the Operating Partnership can redeem their Units by providing written notification to the General Partner of the Operating Partnership. Unless the General Partner provides notice of a redemption restriction to the holder, redemption must be made within seven business days after receipt of the holder’s notice. The redemption can be effectuated, as determined by the General Partner, either by exchanging the Units for shares of common stock of the Company on a one-for-one basis, subject to adjustment, or by paying cash equal to the fair market value of such shares. Prior requests for redemption have generally been fulfilled with shares of common stock of the Company, and we intend to continue this practice. If each Unit of the Operating Partnership were redeemed as of December 31, 2013, we could satisfy our redemption obligations by making an aggregate cash payment of approximately $80,223 or by issuing 4,597,313 shares of the Company’s common stock. The preferred general partnership units result from preferred capital contributions from the Company. The preferred general partnership units had an aggregate liquidation priority of $75,000 and $225,000 as of December 31, 2013 and 2012, respectively. We are required to make all required distributions on the preferred general partnership units prior to any distribution of cash or assets to the holders of the Units. The consent of the holder of the limited partnership units is required to alter such holder’s rights as to allocations and distributions, to alter or modify such holder’s rights with respect to redemption, to cause the early termination of the Consolidated Operating Partnership, or to amend the provisions of the partnership agreement which requires such consent.
	Preferred Contributions:
	On May 27, 2004, the Company issued 50,000 Depositary Shares, each representing 1/100th of a share of the Company’s 6.236%, Series F Flexible Cumulative Redeemable Preferred Stock, $0.01 par value (the "Series F Preferred Stock"), at an initial offering price of $1,000.00 per Depositary Share. The net proceeds from the issuance of the Series F Preferred Stock were contributed to us in exchange for 6.236% Series F Cumulative Preferred Units (the "Series F Preferred Units") and are reflected in our financial statements as a general partner preferred unit contribution. Dividends on the Series F Preferred Stock are cumulative from the date of initial issuance and are payable quarterly in arrears. The coupon rate of the Series F Preferred Stock resets every quarter at 2.375% plus the greater of (i) the 30 year Treasury constant maturity treasury ("CMT") Rate, (ii) the 10 year Treasury CMT Rate or (iii) 3-month LIBOR. For the fourth quarter of 2013, the coupon rate was 6.065%. With respect to the payment of dividends and amounts upon liquidation, dissolution or winding up, the Series F Preferred Stock ranks senior to payments on the Company’s Common Stock and pari passu with the Company’s Series G Preferred Stock (hereinafter defined). The Series F Preferred Stock is redeemable for cash at the Company's option, in whole or in part, at a redemption price of $1,000.00 per Depositary Share, or $50,000 in the aggregate, plus dividends accrued and unpaid to the redemption date. The Series F Preferred Units have no stated maturity and are not convertible into any other securities of the Company. In October 2008, we entered into an interest rate swap agreement to mitigate our exposure to floating interest rates related to the forecasted reset rate of the coupon rate of the Series F Preferred Stock, which matured on October 1, 2013 (see Note 16). On February 3, 2014, the Company called for the redemption of the Series F Preferred Stock (see Note 19).
	On May 27, 2004, the Company issued 25,000 Depositary Shares, each representing 1/100th of a share of the Company’s 7.236%, Series G Flexible Cumulative Redeemable Preferred Stock, $0.01 par value (the "Series G Preferred Stock"), at an initial offering price of $1,000.00 per Depositary Share. The net proceeds from the issuance of the Series G Preferred Stock were contributed to us in exchange for 7.236% Series G Cumulative Preferred Units (the "Series G Preferred Units") and are reflected in our financial statements as a general partner preferred unit contribution. Dividends on the Series G Preferred Stock are cumulative from the date of initial issuance and are payable semi-annually in arrears for the period from the date of original issuance of the Series G Preferred Stock through March 31, 2014 (the "Series G Initial Fixed Rate Period"), commencing on September 30, 2004, at a rate of 7.236% per annum of the liquidation preference (the "Series G Initial Distribution Rate") (equivalent to $72.36 per Depositary Share). On or after March 31, 2014, the Series G Initial Distribution Rate is subject to reset, at the Company’s option, subject to certain conditions and parameters, at fixed or floating rates and periods. Fixed rates and periods will be determined through a remarketing procedure. Floating rates during floating rate periods will equal 2.500% (the initial credit spread), plus the greater of (i) the 3-month LIBOR, (ii) the 10 year Treasury CMT Rate, and (iii) the 30 year Treasury CMT Rate, reseting quarterly. Dividends on the Series G Preferred Stock are payable quarterly in arrears for floating rate periods. With respect to the payment of dividends and amounts upon liquidation, dissolution or winding up, the Series G Preferred Stock ranks senior to payments on the Company’s Common Stock and pari passu with the Company’s Series F Preferred Stock. On or after March 31, 2014, the Series G Preferred Stock is redeemable for cash at the Company's option, in whole or in part, at a redemption price of $1,000.00 per Depositary Share, or $25,000 in the aggregate, plus dividends accrued and unpaid to the redemption date. The Series G Preferred Units have no stated maturity and are not convertible into any other securities of the Company. On February 3, 2014, the Company called for the redemption of the Series G Preferred Stock (see Note 19).
	On January 13, 2006, the Company issued 6,000,000 Depositary Shares, each representing 1/10,000th of a share of the Company’s 7.25%, Series J Cumulative Redeemable Preferred Stock, $0.01 par value (the "Series J Preferred Stock"), at an initial offering price of $25.00 per Depositary Share. The net proceeds from the issuance of the Series J Preferred Stock were contributed to us in exchange for 7.25% Series J Cumulative Preferred Units (the "Series J Preferred Units") and are reflected in our financial statements as a general partner preferred unit contribution. The Series J Preferred Stock is redeemable for cash at the Company's option, in whole or in part, at a redemption price equivalent to $25.00 per Depositary Share, or $150,000 in the aggregate, plus dividends accrued and unpaid to the redemption date. On December 21, 2012, the Company redeemed 2,000,000 Depositary Shares of the Series J Preferred Stock at a redemption price of $25.00 per Depositary Share, and paid a pro-rated fourth quarter dividend of $0.407812 per Depositary Share, totaling $816. An equivalent number of Series J Preferred Units were redeemed on December 21, 2012 as well. One-third of the initial offering costs associated with the issuance of the Series J Preferred Units, as well as costs associated with the partial redemption, totaled $1,804 and are reflected as a deduction from net loss in determining earnings per unit for the year ended December 31, 2012. The remaining 4,000,000 Depositary Shares of the Series J Preferred Stock were redeemed on April 11, 2013, at a redemption price of $25.00 per Depositary Share, and the Company paid a pro-rated second quarter dividend of $0.055382 per Depositary Share, totaling $221. An equivalent number of Series J Preferred Units were redeemed on April 11, 2013 as well. The remaining initial offering costs associated with the issuance of the Series J Preferred Units, as well as costs associated with the redemption, totaled $3,546 and are reflected as a deduction from net income in determining earnings per unit for the year ended December 31, 2013.
	On August 21, 2006, the Company issued 2,000,000 Depositary Shares, each representing 1/10,000th of a share of the Company’s 7.25%, Series K Flexible Cumulative Redeemable Preferred Stock, $0.01 par value (the "Series K Preferred Stock"), at an initial offering price of $25.00 per Depositary Share. The net proceeds from the issuance of the Series K Preferred Stock were contributed to us in exchange for 7.25% Series K Cumulative Preferred Units (the "Series K Preferred Units") and are reflected in our financial statements as a general partner preferred unit contribution. The Series K Preferred Stock is redeemable for cash at the Company's option, in whole or in part, at a redemption price equivalent to $25.00 per Depositary Share, or $50,000 in the aggregate, plus dividends accrued and unpaid to the redemption date. On July 18, 2013, the Company fully redeemed the Series K Preferred Stock at a redemption price of $25.00 per Depositary Share, and paid a pro-rated third quarter dividend of $0.090625 per Depositary Share, totaling $181. An equivalent number of Series K Preferred Units were redeemed on July 18, 2013 as well. The initial offering costs associated with the issuance of the Series K Preferred Units, as well as costs associated with the redemption, totaled $2,121 and are reflected as a deduction from net income in determining earnings per share for the year ended December 31, 2013.
	The Company has 10,000,000 shares of preferred stock authorized. All series of preferred stock have no stated maturity (although the Company may redeem all such preferred stock on or following their optional redemption dates at its option, in whole or in part).
	The following table summarizes the preferred units outstanding at December 31, 2013 and 2012:

	For the years ended December 31, 2013, 2012 and 2011, 105,028, 535,026, and 125,784 limited partnership units, respectively, were converted into an equivalent number of general partnership units, resulting in a reclassification of $996, $4,763 and $1,109, respectively, between Limited Partners Units and General Partner Units.
	During the years ended December 31, 2013, 2012 and 2011, the Company issued 8,400,000, 9,400,000 and 17,300,000 shares of the Company’s common stock in an underwritten public offering. Net proceeds to the Company for the years ended December 31, 2013, 2012 and 2011, were $132,050, $116,715 and $201,150, respectively. The proceeds were contributed to us in exchange for Units and are reflected in our financial statements as a general partner contribution.

During the year ended December 31, 2011, the Company issued 115,856 shares of the Company’s common stock under the 2011 ATM resulting in net proceeds to the Company of $1,391. These net proceeds were contributed to us in exchange for an equivalent number of Units and are reflected in our financial statements as a general partner contribution. On February 29, 2012, we terminated the 2011 ATM in preparation for the commencement of the 2012 ATM (defined hereafter).
	On March 1, 2012, the Company and the Operating Partnership entered into distribution agreements with sales agents to sell up to 12,500,000 shares of the Company’s common stock, for up to $125,000 aggregate gross sale proceeds, from time to time in "at-the-market" offerings (the "2012 ATM"). During the years ended December 31, 2013 and 2012, the Company issued 2,315,704 and 1,532,598 shares, respectively, of the Company’s common stock under the 2012 ATM resulting in net proceeds to the Company of $41,735 and $18,063. These net proceeds were contributed to us in exchange for an equivalent number of Units and are reflected in our financial statements as a general partner contribution.
	Under the terms of the ATMs, sales are to be made primarily in transactions that are deemed to be "at-the-market" offerings, including sales made directly on the New York Stock Exchange or sales made through a market maker other than on an exchange or by privately negotiated transactions.

	Deferred income taxes represent the tax effect of the temporary differences between the book and tax basis of assets and liabilities. Deferred tax assets (liabilities) include the following as of December 31, 2013 and 2012:
		2013			2012
	Impairment of Real Estate	$	5,185		$	5,519

	Total Deferred Tax Liabilities	$	(1,969	)	$	(1,915	)
	Total Net Deferred Tax Liabilities	$	(133	)	$	(169	)
	A valuation allowance is recorded if we believe it is more likely than not that all or some portion of our deferred tax assets will not be realized. We do not have projections of future taxable income or other sources of taxable income in the taxable REIT subsidiaries significant enough to allow us to believe it is more likely than not that we will realize our deferred tax assets. Therefore, we have recorded a valuation allowance against our deferred tax assets. An increase or decrease in the valuation allowance that results from a change in circumstances, and which causes a change in our judgment about the realizability of the related deferred tax assets, is included in the current tax provision.
	The income tax benefit (provision) pertaining to income (loss) from continuing operations and gain on sale of real estate differs from the amounts computed by applying the applicable federal statutory rate as follows:
		2013			2012			2011

	Net Income Tax Benefit (Provision)	$	3		$	(5,522	)	$	(902	)
	We evaluate tax positions taken in the financial statements on a quarterly basis under the interpretation for accounting for uncertainty in income taxes. As a result of this evaluation, we may recognize a tax benefit from an uncertain tax position only if it is "more-likely-than-not" that the tax position will be sustained on examination by taxing authorities. As of December 31, 2013, we do not have any unrecognized tax benefits.
	We file income tax returns in the U.S., and various states and foreign jurisdictions. In general, the statutes of limitations for income tax returns remain open for the years 2010 through 2013.
	IRS Tax Refund
	On August 24, 2009, we received a private letter ruling from the IRS granting favorable loss treatment under Sections 331 and 336 of the Code on the tax liquidation of one of our former taxable REIT subsidiaries. On November 6, 2009, legislation was signed that allowed businesses with net operating losses for 2008 or 2009 to carry back those losses for up to five years. As a result, we received a refund from the IRS of $40,418 in the fourth quarter of 2009 (the "Refund") in connection with this tax liquidation. The IRS examination team, which is required by statute to review all refund claims in excess of $2,000 on behalf of the Joint Committee on Taxation, indicated to us that it disagreed with certain of the property valuations we obtained from an independent valuation expert in support of our fair value of the liquidated taxable REIT subsidiary and our claim for the Refund. During the year ended December 31, 2012, we reached an agreement with the regional office of the IRS on a proposed adjustment to the Refund. The total agreed-upon adjustment to taxable income was $13,700, which equates to $4,806 of taxes owed. We were also required to pay accrued interest of approximately $500. During the year ended December 31, 2012, the Operating Partnership recorded a charge for the agreed-upon adjustment and the related estimated accrued interest which was reflected as a component of income tax expense. During the year ended December 31, 2013, the settlement amount was approved by the Joint Committee on Taxation and we paid the agreed upon taxes and related accrued interest.
	As a result of the Joint Committee on Taxation's approval during 2013, we entered into closing agreements with the IRS that determined the timing of the settlement on the tax characterization of the limited partners of the Operating Partnership and the stockholders of the Company. Pursuant to these closing agreements, $8,238 of the preferred stock distributions for the year ended December 31, 2012 are taxable as capital gain.

Stock Based Compensation	'
	15. Stock Based Compensation
	The Company maintains five stock incentive plans, (the "Stock Incentive Plans") which are administered by the Company’s Compensation Committee of the Board of Directors. There are 11,500,000 shares of the Company’s common stock authorized for issuance under the Stock Incentive Plans. Only officers, certain employees, the Company’s Independent Directors and our affiliates generally are eligible to participate in the Stock Incentive Plans.
	The Stock Incentive Plans authorize (i) the grant of stock options that qualify as incentive stock options under Section 422 of the Code, (ii) the grant of stock options that do not so qualify, (iii) restricted stock/unit awards (including awards subject to performance conditions), and (iv) dividend equivalent rights. The exercise price of the stock options is determined by the Company’s Compensation Committee. Special provisions apply to awards granted under the Stock Incentive Plans in the event of a change in control in the Consolidated Operating Partnership. As of December 31, 2013, awards covering 373,243 shares of common stock were available to be granted under the Stock Incentive Plans.
	In September 1994, the Company’s Board of Directors approved and the Company adopted a 401(k)/Profit Sharing Plan. Under the Company’s 401(k)/Profit Sharing Plan, all eligible employees may participate by making voluntary contributions. The Company may make, but are not required to make, matching contributions, which are funded by the Operating Partnership. For the years ended December 31, 2013, 2012 and 2011, matching contributions of $300, $284 and $197, respectively, were recorded.
	For the years ended December 31, 2013, 2012 and 2011, we awarded 284,461, 565,137 and 292,339 shares, respectively, of restricted stock awards to certain employees, which had a fair value of $4,719, $7,065 and $3,248 on the date of approval by the Compensation Committee of the Board of Directors and/or the Board of Directors. We issued Units to the Company in the same amounts. These restricted stock awards generally vest over a period of three years. Compensation expense will be charged to earnings over the vesting period for the shares expected to vest except if the recipient is not required to provide future service in exchange for vesting of the share. If vesting of a recipient's restricted stock awards is not contingent upon future service, the expense is recognized immediately at the date of grant. During the years ended December 31, 2013 and 2012, we recognized $1,008 and $3,649 of compensation expense related to restricted stock awards granted to our Chief Executive Officer for which future service was not required.
	The Board of Directors adopted the 2013 Long-Term Incentive Program ("LTIP") and effective July 1, 2013, certain officers and employees were granted 718,960 performance units ("LTIP Unit Awards"). The LTIP Unit Awards had a fair value of $5,411 on the grant date as determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation. The LTIP Unit Awards vest based upon the relative total shareholder return ("TSR") of our common stock compared to the TSRs of the MSCI US REIT Index and the NAREIT Industrial Index. The TSR for half of the granted units is calculated based upon the performance from July 1, 2013 through June 30, 2014 and the other half is calculated based upon the performance from July 1, 2013 through December 31, 2015. Compensation expense will be charged to earnings on a straight-line basis over the respective performance periods. At the end of the respective performance periods, each participant will be issued shares of our common stock equal to the maximum shares issuable to the participant for the performance period multiplied by a percentage, ranging from 0% to 100%, based on our TSR as compared to the TSR of the MSCI US REIT Index and the NAREIT Industrial Index. The participants will also be entitled to dividend equivalents for shares issued pursuant to vested LTIP Unit Awards, of which dividend equivalents represent any common dividends that would have been paid with respect to such issued shares after the grant of the LTIP Unit Awards and prior to the date of settlement.
	As mentioned above, the fair value of the LTIP Unit Awards at issuance was determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation using the following assumptions:
	Expected dividend yield	2.22	%
	Expected volatility - range used	24.28% - 34.66%
	Expected volatility - weighted average	30.61	%
	Risk-free interest rate	0.03% - 0.71%
	Expected term	1 - 2.5 years
	For the years ended December 31, 2013, 2012 and 2011, we recognized $6,202, $8,559 and $3,759 in amortization related to restricted stock and unit awards and LTIP Unit Awards, of which $34, $21 and $0, respectively, was capitalized in connection with development activities. At December 31, 2013, we had $7,319 in unrecognized compensation related to unvested restricted stock and LTIP Unit Awards. The weighted average period that the unrecognized compensation is expected to be recognized is 0.83 years.
	Restricted stock and unit award and LTIP Unit Award transactions for the year ended December 31, 2013 are summarized as follows:
		Awards		Weighted
				Average
				Grant Date
				Fair Value
	Outstanding at December 31, 2012 (Restricted Stock and Unit)	772,127		$	7.02

16. Derivatives

Our objectives in using interest rate derivatives are to add stability to interest expense or preferred stock dividends and to manage our cash flow volatility and exposure to interest rate movements. To accomplish this objective, we primarily use interest rate swaps as part of our interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

Our Series F Preferred Units are subject to a coupon rate reset. The coupon rate resets every quarter at 2.375% plus the greater of i) the 30 year Treasury CMT Rate, ii) the 10 year Treasury CMT Rate or iii) 3-month LIBOR. For the fourth quarter of 2013, the new coupon rate was 6.065%. In October 2008, we entered into an interest rate swap agreement with a notional value of $50,000 to mitigate our exposure to floating interest rates related to the forecasted reset rate of the coupon rate of our Series F Preferred Units (the "Series F Agreement"). This Series F Agreement fixes the 30 year Treasury CMT rate at 5.2175%. Accounting guidance for derivatives does not permit hedge accounting treatment related to equity instruments and therefore the mark-to-market gains or losses related to this agreement are recorded in the statement of operations. For the years ended December 31, 2013 and 2012, gains of $52 and losses of $328, respectively, are recognized as mark-to-market gain (loss) on interest rate protection agreements. Quarterly payments are treated as a component of the mark-to-market gains or losses and totaled $774 and $1,169 for the years ended December 31, 2013 and 2012, respectively. The Series F Agreement matured on October 1, 2013.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in other comprehensive income ("OCI") and is subsequently reclassified to earnings through interest expense over the life of the derivative or over the life of the debt. In the next 12 months, we expect to amortize approximately $1,358 into net income by increasing interest expense for interest rate protection agreements we settled in previous periods.

The following is a summary of the terms of our Series F Agreement and its fair value, which is included in accounts payable, accrued expenses and other liabilities on the accompanying consolidated balance sheets:

The guidance for fair value measurement of financial instruments includes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The valuation of the Series F Agreement was determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of the instrument. This analysis reflected the contractual terms of the agreement including the period to maturity. In adjusting the fair value of the Series F Agreement for the effect of nonperformance risk, we had considered the impact of netting and any applicable credit enhancement. To comply with the provisions of fair value measurement, we calculated a credit valuation adjustment to appropriately reflect both our own nonperformance risk and our counterparty’s nonperformance risk in the fair value measurements. We considered the Series F Agreement to be classified as Level 3 in the fair value hierarchy due to a significant number of unobservable inputs. The Series F Agreement swapped a fixed rate of 5.2175% for floating rate payments based on 30 year Treasury CMT rate. No market observable prices exist for long dated Treasuries. Therefore, we have classified the Series F Agreement in its entirety as Level 3.

The following table presents a reconciliation of our liability classified as Level 3 at December 31, 2013 and 2012:

	18. Commitments and Contingencies
	In the normal course of business, we are involved in legal actions arising from the ownership of our industrial properties. In our opinion, the liabilities, if any, that may ultimately result from such legal actions are not expected to have a materially adverse effect on our consolidated financial position, operations or liquidity.
	Three properties have leases granting the tenants options to purchase the property. Such options are exercisable at various times at appraised fair market value or at a fixed purchase price in excess of our depreciated cost of the asset. We have no notice of any exercise of any tenant purchase option.
	At December 31, 2013, we had an outstanding letter of credit and performance bonds in the aggregate amount of $6,102.
	In conjunction with the development of industrial properties, we have entered into agreements with general contractors for the construction of industrial buildings. At December 31, 2013, we have three industrial buildings totaling approximately 0.8 million square feet of GLA that are under construction. The estimated total construction costs as of December 31, 2013, are approximately $49,200 (unaudited). Of this amount, approximately $23,900 (unaudited) remains to be funded. There can be no assurance that the actual completion cost will not exceed the estimated completion cost stated above.
	Ground and Operating Lease Agreements
	For the years ended December 31, 2013, 2012 and 2011, we recognized $1,440, $1,565 and $1,955, respectively, in operating and ground lease expense.
	Future minimum rental payments under the terms of all non-cancelable ground and operating leases under which we are the lessee as of December 31, 2013 are as follows:
	2014	$	1,824
	2015	1,660
	2016	1,673
	2017	1,702
	2018	1,100
	Thereafter	25,117
	Total*	$	33,076

	*	Minimum rental payments have not been reduced by minimum sublease rentals of $6,832 due in the future under non-cancelable subleases.

	From January 1, 2014 to February 27, 2014, we acquired one industrial property for a purchase price of approximately $13,400, excluding costs incurred in conjunction with the acquisition and we sold one industrial property for approximately $1,335. Additionally, in January 2014 the 2003 Net Lease Joint Venture sold two industrial properties (see Note 6).
	On January 29, 2014, we entered into a $200,000 unsecured loan with a seven-year term. The loan features interest-only payments and initially bears an interest rate of LIBOR plus 175 basis points. The rate is subject to adjustment based on our leverage ratio or credit ratings. We also entered into interest rate swap agreements, with an aggregate notional value of $200,000, to convert the term loan's LIBOR rate to a fixed rate of approximately 4.04% per annum, based on the loan's current spread.
	On February 3, 2014, the Company announced that it will redeem all 50,000 Depositary Shares of its Series F Preferred Stock. The redemption price will be $1,000.00 per Depositary Share, or $50,000, plus all accumulated and unpaid distributions to and including the date of redemption, March 6, 2014. The Company also announced that it will redeem all 25,000 Depositary Shares of its Series G Preferred Stock. The redemption price will be $1,000.00 per Depositary Share, or $25,000 plus all accumulated and unpaid distributions to and including the date of redemption, March 31, 2014. An equivalent number of Series F Preferred Units and Series G Preferred Units will also be redeemed on the respective redemption dates.

Accounting Policies [Abstract]	'
Reclassification and Other Presentation Matters	'
	Certain reclassifications have been made to the 2012 Consolidated Balance Sheet to conform to the 2013 presentation.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	Cash and cash equivalents include all cash and liquid investments with an initial maturity of three months or less. The carrying amount approximates fair value due to the short term maturity of these investments.
Investment in Real Estate and Depreciation	'
	Investment in Real Estate and Depreciation
	Investment in real estate is carried at cost, less accumulated depreciation and amortization. We review our properties on a quarterly basis for impairment and provide a provision if impairments exist. To determine if an impairment may exist, we review our properties and identify those that have had either an event of change or event of circumstances warranting further assessment of recoverability (such as a decrease in occupancy or decline in general market conditions). If further assessment of recoverability is needed, we estimate the future net cash flows expected to result from the use of the property and its eventual disposition on an individual property basis. If the sum of the expected future net cash flows (undiscounted and without interest charges) is less than the carrying amount of the property on an individual property basis, we will recognize an impairment loss based upon the estimated fair value of such property. For properties we consider held for sale, we cease depreciating the properties and value the properties at the lower of depreciated cost or fair value, less costs to dispose. If circumstances arise that were previously considered unlikely, and, as a result, we decide not to sell a property previously classified as held for sale, we will reclassify such property as held and used. Such property is measured at the lower of its carrying amount (adjusted for any depreciation and amortization expense that would have been recognized had the property been continuously classified as held and used) or fair value at the date of the subsequent decision not to sell. We classify properties as held for sale when all criteria within the Financial Accounting Standards Board’s (the "FASB") guidance on the impairment or disposal of long-lived assets are met.
	Interest costs, real estate taxes, compensation costs of development personnel and other directly related costs incurred during construction periods are capitalized and depreciated commencing with the date the property is substantially completed. Upon substantial completion, we reclassify construction in progress to building, tenant improvements and leasing commissions. Such costs begin to be capitalized to the development projects from the point we are undergoing necessary activities to get the development ready for its intended use and ceases when the development projects are substantially completed and held available for occupancy.
	Depreciation expense is computed using the straight-line method based on the following useful lives:
		Years
	Buildings and Improvements	7 to 50
	Land Improvements	3 to 20
	Furniture, Fixtures and Equipment	4 to 10
	Tenant Improvements	Shorter of Lease Term or Useful Life
	Construction expenditures for tenant improvements, leasehold improvements and leasing commissions (inclusive of compensation costs of personnel attributable to leasing) are capitalized and amortized over the terms of each specific lease. Capitalized compensation costs of personnel attributable to leasing relate to time directly attributable to originating leases with independent third parties that result directly from and are essential to originating those leases and would not have been incurred had these leasing transactions not occurred. Repairs and maintenance are charged to expense when incurred. Expenditures for improvements are capitalized.
	Upon acquisition of a property, we allocate the purchase price of the property based upon the fair value of the assets acquired and liabilities assumed, which generally consists of land, buildings, tenant improvements, leasing commissions and intangible assets including in-place leases, above market and below market leases and tenant relationships. We allocate the purchase price to the fair value of the tangible assets of an acquired property by valuing the property as if it were vacant. Acquired above and below market leases are valued based on the present value of the difference between prevailing market rates and the in-place rates measured over a period equal to the remaining term of the lease for above market leases and the initial term plus the term of any below market fixed rate renewal options for below market leases. The above market lease values are amortized as a reduction of rental revenue over the remaining term of the respective leases, and the below market lease values are amortized as an increase to base rental revenue over the remaining initial terms plus the terms of any below market fixed rate renewal options of the respective leases.
	The purchase price is further allocated to in-place lease values and tenant relationships based on our evaluation of the specific characteristics of each tenant’s lease and our overall relationship with the respective tenant. The value of in-place lease intangibles and tenant relationships, which are included as components of deferred leasing intangibles, net are amortized over the remaining lease term (and expected renewal periods of the respective lease for tenant relationships) as adjustments to depreciation and other amortization expense. If a tenant terminates its lease early, the unamortized portion of the tenant improvements, leasing commissions, above and below market leases, the in-place lease value and tenant relationships is immediately written off.
	Deferred leasing intangibles, net of accumulated amortization, included in our total assets and total liabilities consist of the following:
		December 31,		December 31,
		2013		2012
	In-Place Leases	$	14,045	$	15,216
	Above Market Leases	3,004		3,829
	Tenant Relationships	9,532		10,329
	Total Included in Total Assets, Net of $26,663 and $32,614 of Accumulated Amortization	$	26,581	$	29,374
	Below Market Leases	$	11,879	$	13,597
	Total Included in Total Liabilities, Net of $7,604 and $8,527 of Accumulated Amortization	$	11,879	$	13,597
	Amortization expense related to in-place leases and tenant relationships, exclusive of amortization expense related to in-place leases and tenant relationships included in discontinued operations, was $5,615, $6,303 and $9,202 for the years ended December 31, 2013, 2012 and 2011, respectively. Rental revenues increased by $465, $666 and $1,340 related to net amortization of above/(below) market leases, exclusive of net amortization related to above/(below) market leases included in discontinued operations, for the years ended December 31, 2013, 2012 and 2011, respectively. We will recognize net amortization related to deferred leasing intangibles over the next five years, for properties owned as of December 31, 2013 as follows:
		Estimated		Estimated Net
		Amortization		Increase to
		of In-Place		Rental Revenues
		Leases and Tenant		Related to
		Relationships		Above and Below

Foreign Currency Transactions and Translation	'
	Foreign Currency Transactions and Translation
	At December 31, 2013, we owned a land parcel located in Toronto, Canada for which the functional currency was determined to be the Canadian dollar. The assets and liabilities related to this land parcel are translated to U.S. dollars from the Canadian dollar based on the current exchange rate prevailing at each balance sheet date. The income statement accounts related to this land parcel are translated using the average exchange rate for the period. The resulting translation adjustments are included in accumulated other comprehensive income.
Deferred Financing Costs	'
	Deferred Financing Costs
	Deferred financing costs include fees and costs incurred to obtain long-term financing. These fees and costs are being amortized over the terms of the respective loans. Accumulated amortization of deferred financing costs was $16,520 and $14,551 at December 31, 2013 and 2012, respectively. Unamortized deferred financing costs are written-off when debt is retired before the maturity date.
Investment in and Advances to Other Real Estate Partnerships	'
	Investment in and Advances to Other Real Estate Partnerships
	Investment in and Advances to Other Real Estate Partnerships represents our limited partnership interests in and advances to, through the Operating Partnership, the Other Real Estate Partnerships. We account for our Investment in and Advances to Other Real Estate Partnerships under the equity method of accounting. Under the equity method of accounting, our share of earnings or losses of the Other Real Estate Partnerships is reflected in income as earned and contributions or distributions increase or decrease, respectively, our Investment in and Advances to Other Real Estate Partnerships as paid or received, respectively.
	On a continuous basis, we assess whether there are any indicators that the value of our Investment in and Advances to Other Real Estate Partnerships may be impaired. An investment is impaired if our estimate of the value of the investment is less than the carrying value of the investment, and such decline in value is deemed to be other than temporary. To the extent impairment has occurred, the loss shall be measured as the excess of the carrying amount of the investment over the fair value of the investment. Our estimates of fair value for each investment are based on a number of subjective assumptions that are subject to economic and market uncertainties including, among others, demand for space, market rental rates and operating costs, the discount rate used to value the cash flows of the properties and the discount rate used to value the debt. As these factors are difficult to predict and are subject to future events that may alter our assumptions, our fair values estimated by management in the impairment analyses may not be realized.

	Investments in joint ventures represent our limited partnership interests in our Joint Ventures. We account for our investments in joint ventures under the equity method of accounting, as we do not have a majority voting interest, operational control or financial control. Control is determined using accounting standards related to the consolidation of joint ventures and variable interest entities. In order to assess whether consolidation of a variable interest entity is required, an enterprise is required to qualitatively assess the determination of the primary beneficiary of a variable interest entity ("VIE") based on whether the entity (1) has the power to direct matters that most significantly impact the activities of the VIE and (2) has the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Additionally, they require an ongoing reconsideration of the primary beneficiary and provide a framework for the events that trigger a reassessment of whether an entity is a VIE.
	Under the equity method of accounting, our share of earnings or losses of our Joint Ventures is reflected in income as earned and contributions or distributions increase or decrease our investments in joint ventures as paid or received, respectively. Differences between our carrying value of our investments in joint ventures and our underlying equity of such Joint Ventures are amortized over the respective lives of the underlying assets.
	On a continuous basis, we assess whether there are any indicators that the value of our investments in joint ventures may be impaired. An investment is impaired if our estimate of the fair value of the investment is less than the carrying value of the investment, and such decline in fair value is deemed to be other than temporary. To the extent impairment has occurred, the loss shall be measured as the excess of the carrying amount of the investment over the fair value of the investment. Our estimates of fair value for each investment are based on a number of subjective assumptions that are subject to economic and market uncertainties including, among others, demand for space, market rental rates and operating costs, the discount rate used to value the cash flows of the properties, the capitalization rate used to estimate the terminal value of the underlying properties and the discount rate used to value the Joint Ventures’ debt. As these factors are difficult to predict and are subject to future events that may alter our assumptions, our fair values estimated in the impairment analyses may not be realized.
Limited Partners Units	'
	Limited Partners Units
	Limited partner Units are reported within Partners’ Capital in the balance sheet as of December 31, 2013 and 2012 because they are not redeemable for cash or other assets (a) at a fixed or determinable date, (b) at the option of the Unitholder or (c) upon the occurrence of an event that is not solely within the control of the Operating Partnership. Redemption can be effectuated, as determined by the General Partner, either by exchanging the Units for shares of common stock of the Company on a one-for-one basis, subject to adjustment, or by paying cash equal to the fair market value of such shares.
	The Operating Partnership is the only significant asset of the Company and economic, fiduciary and contractual means align the interests of the Company and the Operating Partnership. The Board of Directors and officers of the Company direct the Company to act when acting in its capacity as sole general partner of the Operating Partnership. Because of this, the Operating Partnership is deemed to have effective control of the form of redemption consideration. As of December 31, 2013, all criteria were met for the Operating Partnership to control the actions or events necessary to issue the maximum number of the Company’s common shares required to be delivered upon redemption of all remaining Units.
Stock Based Compensation	'
	Stock Based Compensation
	We measure compensation cost for all stock-based awards at fair value on the date of grant and recognize compensation expense over the service period for awards expected to vest.
	Net income, net of preferred unit distributions and redemption of preferred units, is allocated to Unitholders and participating securities based upon their proportionate share of weighted average Units plus weighted average participating securities. Participating securities are unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents. Restricted stock awards granted to employees and directors are considered participating securities as they receive non-forfeitable dividend or dividend equivalents at the same rate as Units. See Note 11 for further disclosure about participating securities.
Revenue Recognition	'
	Revenue Recognition
	Rental income is recognized on a straight-line method under which contractual rent increases are recognized evenly over the lease term. Tenant recovery income includes payments from tenants for real estate taxes, insurance and other property operating expenses and is recognized as revenue in the same period the related expenses are incurred by us.
	Revenue is generally recognized on payments received from tenants for early lease terminations upon the effective termination of a tenant’s lease and when we have no further obligations under the lease.
	Interest income on notes receivable is recognized based on the accrual method unless a significant uncertainty of collection exists. If a significant uncertainty exists, interest income is recognized as collected.
	We provide an allowance for doubtful accounts against the portion of tenant accounts receivable including deferred rent receivable, which is estimated to be uncollectible. Accounts receivable in the consolidated balance sheets are shown net of an allowance for doubtful accounts of $1,352 and $1,852 as of December 31, 2013 and 2012, respectively. Deferred rent receivable in the consolidated balance sheets is shown net of an allowance for doubtful accounts of $1,694 and $1,733 as of December 31, 2013 and 2012, respectively. For accounts receivable we deem uncollectible, we use the direct write-off method.
Gain on Sale of Real Estate	'
	Gain on Sale of Real Estate
	Gain on sale of real estate is recognized using the full accrual method, when appropriate. Gains relating to transactions which do not meet the full accrual method of accounting are deferred and recognized when the full accrual method of accounting criteria are met or by using the installment or deposit methods of profit recognition, as appropriate in the circumstances. As the assets are sold, their costs and related accumulated depreciation are written off with resulting gains or losses reflected in net income or loss. Estimated future costs to be incurred by us after completion of each sale are included in the determination of the gain on sales.
Notes Receivable	'
	Notes Receivable
	Notes receivable are primarily comprised of mortgage notes receivable that we have made in connection with sales of real estate assets. The notes receivable are recorded at fair value at the time of issuance. Discounts on notes receivable are accreted over the life of the related note receivable. Interest income is accrued as earned. Notes receivable are considered past due when a contractual payment is not remitted in accordance with the terms of the note agreement. On a quarterly basis, we evaluate the collectability of each mortgage note receivable on an individual basis based on various factors which may include payment history, expected fair value of the collateral and internal and external credit information. A loan is considered impaired when, based upon current information and events, it is probable that we will be unable to collect all amounts due under the existing contractual terms. When a loan is considered impaired, the amount of the loss accrual is calculated by comparing the carrying amount of the note receivable to the present value of expected future cash flows. Since the majority of our notes receivable are collateralized by a first mortgage, the loans have risk characteristics similar to the risks in owning commercial real estate.
Income Taxes	'
	Income Taxes
	In accordance with partnership taxation, each of the partners is responsible for reporting their share of taxable income or loss.
	A benefit/provision has been made for federal, state and local income taxes in the accompanying consolidated financial statements. We may also be subject to certain federal excise and franchise taxes if we engage in certain types of transactions. In accordance with FASB’s guidance, the total benefit/provision has been separately allocated to income (loss) from continuing operations, income (loss) from discontinued operations and gain (loss) on sale of real estate. The provision for excise and franchise taxes has been reflected in general and administrative expense in the consolidated statements of operations and has not been separately stated due to its insignificance.
	During 2005, we recorded a $745 franchise tax reserve related to a potential state franchise tax assessment for the 1996-2001 tax years. During the year ended December 31, 2011, we received a refund from the state, representing amounts paid during 2006 related to the 1996-2001 tax years. Based on the refund received and discussions with the taxing authorities, as of December 31, 2011, management believes that it is unlikely that any franchise tax amounts will be assessed by the state for such tax years. As such, during the year ended December 31, 2011, we reversed $745 of franchise taxes. Franchise taxes are recorded within general and administrative expense.
Earnings Per Unit ("EPU")	'
	Earnings Per Unit ("EPU")
	Basic net income (loss) available to Unitholders per Unit is computed by dividing net income (loss) available to Unitholders by the weighted average number of Units outstanding for the period. Diluted net income (loss) available to Unitholders per Unit is computed by dividing net income (loss) available to Unitholders by the sum of the weighted average number of Units outstanding and any dilutive non-participating securities for the period. See Note 11 for further disclosure about EPU.
Derivative Financial Instruments	'
	Derivative Financial Instruments
	Historically, we have used interest rate protection agreements ("Agreements") to fix the interest rate on anticipated offerings of senior unsecured notes or convert floating rate debt and preferred units to fixed rate. Receipts or payments that result from the settlement of Agreements used to fix the interest rate on anticipated offerings of senior unsecured notes are amortized over the life of the derivative or the life of the debt and included in interest expense. Receipts or payments resulting from Agreements used to convert floating rate debt to fixed rate debt are recognized as a component of interest expense. Agreements which qualify for hedge accounting are marked-to-market and any gain or loss that is effective is recognized in other comprehensive income (partners’ capital). Agreements which do not qualify for hedge accounting are marked-to-market and any gain or loss is recognized in net income (loss) available to Unitholders immediately. Amounts accumulated in other comprehensive income during the hedge period are reclassified to earnings in the same period during which the forecasted transaction or hedged item affects net income (loss). The credit risks associated with Agreements are controlled through the evaluation and monitoring of the creditworthiness of the counterparty. In the event that the counterparty fails to meet the terms of Agreements, our exposure is limited to the current value of the interest rate differential, not the notional amount, and our carrying value of Agreements on the balance sheet. See Note 16 for more information on the Agreements.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	Financial instruments other than our derivatives include tenant accounts receivable, notes receivable, accounts payable, other accrued expenses, mortgage loans payable, unsecured credit facility and senior unsecured notes. The fair values of the tenant accounts receivable, accounts payable and other accrued expenses approximate their carrying or contract values. See Note 7 for the fair values of the mortgage loans payable, unsecured credit facility and senior unsecured notes and see Note 4 for the fair value of our notes receivable.
Discontinued Operations	'
	Discontinued Operations
	The FASB’s guidance on financial reporting for the disposal of long lived assets requires that the results of operations and gains or losses on the sale of property or property held for sale be presented in discontinued operations if both of the following criteria are met: (a) the operations and cash flows of the property have been (or will be) eliminated from our ongoing operations as a result of the disposal transaction and (b) we will not have any significant continuing involvement in the operations of the property after the disposal transaction. The guidance also requires prior period results of operations for these properties to be reclassified and presented in discontinued operations in prior consolidated statements of operations.
Segment Reporting	'
	Segment Reporting
	Management views the Consolidated Operating Partnership as a single segment based on its method of internal reporting.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In February 2013, the FASB issued Accounting Standards Update No. 2013-02, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income" ("ASU 2013-02"). ASU 2013-02 requires that public companies present, either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. ASU 2013-02 is effective for annual periods beginning after December 15, 2012, and is to be applied prospectively. The adoption of this guidance did not have a material impact on our consolidated financial statements.
