The_Company

The Company	12 Months Ended
	Dec. 31, 2013
Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
General Basis of Presentation	'
	The Company
	Duke Realty Corporation (the "General Partner") was formed in 1985, and we believe that it qualifies as a real estate investment trust ("REIT") under the provisions of the Internal Revenue Code of 1986, as amended (the "Code"). Duke Realty Limited Partnership (the "Partnership") was formed on October 4, 1993, when the General Partner contributed all of its properties and related assets and liabilities, together with the net proceeds from an offering of additional shares of its common stock, to the Partnership. Unless otherwise indicated, the notes to the consolidated financial statements apply to both the General Partner and the Partnership. The terms "Company," "we," "us" and "our" refer to the General Partner and the Partnership, collectively, and those entities owned or controlled by the General Partner and/or the Partnership.
	The General Partner is the sole general partner of the Partnership, owning approximately 98.7% of the common partnership interests of the Partnership ("General Partner Units") at December 31, 2013. The remaining 1.3% of the common partnership interests ("Limited Partner Units" and, together with the General Partner Units, the "Common Units") are owned by limited partners. As the sole general partner of the Partnership, the General Partner has full, exclusive and complete responsibility and discretion in the day-to-day management and control of the Partnership. The General Partner and the Partnership are operated as one enterprise. The management of the General Partner consists of the same members as the management of the Partnership. As the sole general partner with control of the Partnership, the General Partner consolidates the Partnership for financial reporting purposes, and the General Partner does not have any significant assets other than its investment in the Partnership. Therefore, the assets and liabilities of the General Partner and the Partnership are substantially the same.
	Limited Partners have the right to redeem their Limited Partner Units, subject to certain restrictions. Pursuant to the Fourth Amended and Restated Agreement of Limited Partnership, as amended (the "Partnership Agreement"), the General Partner is obligated to redeem the Limited Partner Units in shares of its common stock, unless it determines in its reasonable discretion that the issuance of shares of its common stock could cause it to fail to qualify as a REIT. Each Limited Partner Unit shall be redeemed for one share of the General Partner's common stock, or, in the event that the issuance of shares could cause the General Partner to fail to qualify as a REIT, cash equal to the fair market value of one share of the General Partner's common stock at the time of redemption, in each case, subject to certain adjustments described in the Partnership Agreement. The Limited Partner Units are not required, per the terms of the Partnership Agreement, to be redeemed in registered shares of the General Partner. The General Partner also owns preferred partnership interests in the Partnership ("Preferred Units").
	We own and operate a portfolio primarily consisting of industrial and office properties and provide real estate services to third-party owners. Substantially all of our Rental Operations (see Note 8) are conducted through the Partnership. We conduct our Service Operations (see Note 8) through Duke Realty Services, LLC, Duke Realty Services Limited Partnership and Duke Construction Limited Partnership ("DCLP"), which are consolidated entities that are 100% owned by a combination of the General Partner and the Partnership. DCLP is owned through a taxable REIT subsidiary.

Summary_of_Significant_Account

Summary of Significant Accounting Policies	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	Summary of Significant Accounting Policies
	Principles of Consolidation
	The consolidated financial statements include our accounts and the accounts of our majority-owned or controlled subsidiaries. The equity interests in these controlled subsidiaries not owned by us are reflected as noncontrolling interests in the consolidated financial statements. All significant intercompany balances and transactions have been eliminated in the consolidated financial statements. Investments in entities that we do not control, and variable interest entities ("VIEs") in which we are not the primary beneficiary, are not consolidated and are reflected as investments in unconsolidated companies under the equity method of reporting.
	Reclassifications
	Certain amounts in the accompanying consolidated financial statements for 2012 and 2011 have been reclassified to conform to the 2013 consolidated financial statement presentation.
	Real Estate Investments
	Rental real property, including land, land improvements, buildings and tenant improvements, are included in real estate investments and are generally stated at cost. Construction in process and undeveloped land are included in real estate investments and are stated at cost. Real estate investments also include our equity interests in unconsolidated joint ventures that own and operate rental properties and hold land for development.
	Depreciation
	Buildings and land improvements are depreciated on the straight-line method over their estimated lives not to exceed 40 and 15 years, respectively, for properties that we develop, and not to exceed 30 and 10 years, respectively, for acquired properties. Tenant improvement costs are depreciated using the straight-line method over the shorter of the useful life of the asset or term of the related lease.
	Cost Capitalization
	Direct and certain indirect costs clearly associated with the development, construction, leasing or expansion of real estate investments are capitalized as a cost of the property. In addition, all leasing commissions paid to third parties for new leases or lease renewals are capitalized. We capitalize a portion of our indirect costs associated with our construction, development and leasing efforts. In assessing the amount of direct and indirect costs to be capitalized, allocations are made based on estimates of the actual amount of time spent in each activity. We do not capitalize any costs attributable to downtime or to unsuccessful projects.
	We capitalize direct and indirect project costs associated with the initial construction of a property up to the time the property is substantially complete and ready for its intended use. In addition, we capitalize costs, including real estate taxes, insurance, and utilities, that have been allocated to vacant space based on the square footage of the portion of the building not held available for immediate occupancy during the extended lease-up periods after construction of the building shell has been completed if costs are being incurred to ready the vacant space for its intended use. If costs and activities incurred to ready the vacant space cease, then cost capitalization is also discontinued until such activities are resumed. Once necessary work has been completed on a vacant space, project costs are no longer capitalized.
	We cease capitalization of all project costs on extended lease-up periods when significant activities have ceased, which does not exceed the shorter of a one-year period after the completion of the building shell or when the property attains 90% occupancy.
	Impairment
	We evaluate our real estate assets, with the exception of those that are classified as held-for-sale, for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If such an evaluation is considered necessary, we compare the carrying amount of that real estate asset, or asset group, with the expected undiscounted cash flows that are directly associated with, and that are expected to arise as a direct result of, the use and eventual disposition of that asset, or asset group. Our estimate of the expected future cash flows used in testing for impairment is based on, among other things, our estimates regarding future market conditions, rental rates, occupancy levels, costs of tenant improvements, leasing commissions and other tenant concessions, assumptions regarding the residual value of our properties at the end of our anticipated holding period and the length of our anticipated holding period and is, therefore, subjective by nature. These assumptions could differ materially from actual results. If our strategy changes or if market conditions otherwise dictate a reduction in the holding period and an earlier sale date, an impairment loss could be recognized and such loss could be material. To the extent the carrying amount of a real estate asset, or asset group, exceeds the associated estimate of undiscounted cash flows, an impairment loss is recorded to reduce the carrying value of the asset to its fair value.
	The determination of the fair value of real estate assets is also highly subjective, especially in markets where there is a lack of recent comparable transactions. We primarily utilize the income approach to estimate the fair value of our income producing real estate assets. We utilize marketplace participant assumptions to estimate the fair value of a real estate asset when an impairment charge is required to be measured. The estimation of future cash flows, as well as the selection of the discount rate and exit capitalization rate used in applying the income approach, are highly subjective measures in estimating fair value.
	Real estate assets classified as held-for-sale are reported at the lower of their carrying value or their fair value, less estimated costs to sell. Once a property is designated as held-for-sale, no further depreciation expense is recorded.
	Purchase Accounting
	We expense acquisition related costs immediately as period costs. We record assets acquired in step acquisitions at their full fair value and record a gain or loss, within acquisition-related activity in our consolidated Statements of Operations, for the difference between the fair value and the carrying value of our existing equity interest. Additionally, contingencies arising from a business combination are recorded at fair value if the acquisition date fair value can be determined during the measurement period.
	We allocate the purchase price of acquired properties to tangible and identified intangible assets based on their respective fair values, using all pertinent information available at the date of acquisition. The allocation to tangible assets (buildings, tenant improvements and land) is based upon management's determination of the value of the property as if it were vacant. This “as-if vacant” value is estimated using an income, or discounted cash flow, approach that relies upon internally determined assumptions that we believe are consistent with current market conditions for similar properties. The most important assumptions in determining the allocation of the purchase price to tangible assets are the exit capitalization rate, discount rate, estimated market rents, and hypothetical expected lease-up periods. The purchase price of real estate assets is also allocated to intangible assets consisting of the above or below market component of in-place leases, the value of in-place leases as well as, to the extent applicable, acquired in-place leases that may have a customer relationship intangible value. There have been no customer relationship intangible assets related to any of our acquisitions to date.
	The value allocable to the above or below market component of an acquired in-place lease is determined based upon the present value (using a discount rate which reflects the risks associated with the acquired leases) of the difference between (i) the contractual amounts to be received pursuant to the lease over its remaining term and (ii) management's estimate of the amounts that would be received using fair market rates over the remaining term of the lease. The amounts allocated to above market leases are included in deferred leasing and other costs in the balance sheet and below market leases are included in other liabilities in the balance sheet; both are amortized to rental income over the remaining terms of the respective leases.
	Factors considered in determining the value allocable to in-place leases include estimates, during hypothetical expected lease-up periods, of space that is actually leased at the time of acquisition, of lost rent at market rates, fixed operating costs that will be recovered from tenants, and theoretical leasing commissions required to execute similar leases. These intangible assets are included in deferred leasing and other costs in the balance sheet and are depreciated over the remaining term of the existing lease.
	Joint Ventures
	We have equity interests in unconsolidated joint ventures that primarily own and operate rental properties or hold land for development. We consolidate those joint ventures that are considered to be VIEs where we are the primary beneficiary. We analyze our investments in joint ventures to determine if the joint venture is considered a VIE and would require consolidation. We (i) evaluate the sufficiency of the total equity investment at risk, (ii) review the voting rights and decision-making authority of the equity investment holders as a group and whether there are any guaranteed returns, protection against losses, or capping of residual returns within the group and (iii) establish whether activities within the venture are on behalf of an investor with disproportionately few voting rights in making this VIE determination.
	To the extent that we (i) are the sole entity that has the power to direct the activities of the VIE and (ii) have the obligation or rights to absorb the VIE's losses or receive its benefits, then we would be determined to be the primary beneficiary of the VIE and would consolidate it. At each reporting period, we re-assess our conclusions as to which, if any, party within the VIE is considered the primary beneficiary.
	At December 31, 2012, we had three unconsolidated joint ventures that met the criteria to be considered VIEs. In December 2013, one of those joint ventures sold assets and repaid all of its third-party debt, thus removing the subordinated financial support in the form of the guarantee of the joint venture's debt, which we had previously provided. As the result of these events, we re-evaluated the sufficiency of the joint venture's equity at risk and determined that it no longer met the criteria to be considered a VIE. As such, we evaluated the joint venture for consolidation under the voting interest model and determined that the equity method of accounting was still appropriate due to the fact that both we and our partner had substantive participating rights over the joint venture's operations.
	After the aforementioned reconsideration event, there were two unconsolidated joint ventures at December 31, 2013 that met the criteria to be considered VIEs. These two unconsolidated joint ventures were formed with the sole purpose of developing, constructing, leasing, marketing and selling or operating properties. The business activities of these unconsolidated joint ventures have been financed through a combination of equity contributions, partner/member loans, and third-party debt that is guaranteed by a combination of us and the other partner/member of each entity. All significant decisions for these unconsolidated joint ventures, including those decisions that most significantly impact each venture's economic performance, require unanimous approval of each joint venture's partners or members. In certain cases, these decisions also require lender approval. Unanimous approval requirements for these unconsolidated joint ventures include entering into new leases, setting annual operating budgets, selling underlying properties, and incurring additional indebtedness. Because no single entity exercises control over the decisions that most significantly affect each joint venture's economic performance, we determined there to be no individual primary beneficiary and that the equity method of accounting is appropriate.
	The following table provides a summary of the carrying value in our consolidated balance sheet, as well as our maximum loss exposure under guarantees for the unconsolidated subsidiaries that we have determined to be VIEs at December 31, 2013 and 2012, respectively (in millions):
		Carrying Value						Maximum Loss
								Exposure
		December 31, 2013			December 31, 2012			December 31, 2013			December 31, 2012
	Investment in unconsolidated companies	$	7.5		$	54.7		$	7.5		$	54.7
	Guarantee obligations (1)	$	(18.4	)	$	(23.3	)	$	(112.8	)	$	(144.8	)
	-1	We are party to guarantees of the third-party debt of these joint ventures, and our maximum loss exposure is equal to the maximum monetary obligation pursuant to the guarantee agreements. We have also recorded a liability for our probable future obligation under a guarantee to the lender of one of these ventures, which is included within the carrying value of our guarantee obligations. Pursuant to an agreement with the lender, we may make member loans to this joint venture that will reduce our maximum guarantee obligation, which is $13.4 million at December 31, 2013, on a dollar-for-dollar basis. The carrying value of our recorded guarantee obligations is included in other liabilities in our Consolidated Balance Sheets.
	To the extent that our joint ventures do not qualify as VIEs, they are consolidated if we control them through majority ownership interests or if we are the managing entity (general partner or managing member) and our partner does not have substantive participating rights. Control is further demonstrated by our ability to unilaterally make significant operating decisions, refinance debt and sell the assets of the joint venture without the consent of the non-managing entity and the inability of the non-managing entity to remove us from our role as the managing entity. Consolidated joint ventures that are not VIEs are not significant in any period presented in these consolidated financial statements.
	We use the equity method of accounting for those joint ventures where we exercise significant influence but do not have control. Under the equity method of accounting, our investment in each joint venture is included on our balance sheet; however, the assets and liabilities of the joint ventures for which we use the equity method are not included on our balance sheet.
	To the extent that we contribute assets to a joint venture, our investment in the joint venture is recorded at our cost basis in the assets that were contributed to the joint venture. To the extent that our cost basis is different than the basis reflected at the joint venture level, the basis difference is amortized over the life of the related asset and included in our share of equity in net income of the joint venture. We recognize gains on the contribution or sale of real estate to joint ventures, relating solely to the outside partner's interest, to the extent the economic substance of the transaction is a sale.
	When circumstances indicate there may have been a reduction in the value of an equity investment, we evaluate whether the loss in value is other than temporary. If we conclude it is other than temporary we recognize an impairment charge to reflect the equity investment at fair value.
	Cash Equivalents
	Investments with an original maturity of three months or less are classified as cash equivalents.
	Valuation of Receivables
	We reserve the entire receivable balance, including straight-line rent, of any tenant with an amount outstanding over 90 days. Additional reserves are recorded for more current amounts, as applicable, where we have determined collectability to be doubtful. Straight-line rent receivables for any tenant with long-term risk, regardless of the status of current rent receivables, are reviewed and reserved as necessary.
	Deferred Costs
	Costs incurred in connection with obtaining financing are deferred and are amortized to interest expense over the term of the related loan. All direct and indirect costs, including estimated internal costs, associated with the leasing of real estate investments owned by us are capitalized and amortized over the term of the related lease. We include lease incentive costs, which are payments made on behalf of a tenant to sign a lease, in deferred leasing costs and amortize them on a straight-line basis over the respective lease terms as a reduction of rental revenues. We include as lease incentives amounts funded to construct tenant improvements owned by the tenant. Unamortized costs are charged to expense upon the early termination of the lease or upon early payment of the financing.
	Deferred leasing and other costs at December 31, 2013 and 2012, excluding such costs for properties classified as held-for-sale, were as follows (in thousands):
		2013				2012
	Deferred leasing costs	$	477,374			$	466,856

		$	226,262			$	10,424
	Convertible Debt Accounting
	Our 3.75% Exchangeable Senior Notes ("Exchangeable Notes") were issued in November 2006 and had an exchange rate of 20.47 common shares per $1,000 principal amount of the notes, representing an exchange price of $48.85 per common share. We repaid the Exchangeable Notes at the first contractual redemption date in December 2011. We accounted for the debt and equity components of our Exchangeable Notes separately, with the value assigned to the debt component equal to the estimated fair value of debt with similar contractual cash flows, but without the conversion feature, resulting in the debt being recorded at a discount. The resulting debt discount was amortized over the period from its issuance through the date of repayment as additional non-cash interest expense.
Interest expense was recognized on the Exchangeable Notes at an effective rate of 5.62%. The increase to interest expense (in thousands) on the Exchangeable Notes, which led to a corresponding decrease to net income, for the year ended December 31, 2011 is summarized as follows:
	2011
Interest expense on Exchangeable Notes, excluding effect of accounting for convertible debt	$	5,769
Effect of accounting for convertible debt	2,090
Total interest expense on Exchangeable Notes	$	7,859
Noncontrolling Interests
Noncontrolling interests relate to the minority ownership interests in the Partnership and interests in consolidated property partnerships that are not wholly-owned by the General Partner or the Partnership. Noncontrolling interests are subsequently adjusted for additional contributions, distributions to noncontrolling holders and the noncontrolling holders' proportionate share of the net earnings or losses of each respective entity. We report noncontrolling interests as a component of total equity.
When a Unit is redeemed (Note 1), the change in ownership is treated as an equity transaction by the General Partner and there is no effect on its earnings or net assets.
Revenue Recognition
Rental and Related Revenue
The timing of revenue recognition under an operating lease is determined based upon ownership of the tenant improvements. If we are the owner of the tenant improvements, revenue recognition commences after the improvements are completed and the tenant takes possession or control of the space. If we determine that the tenant allowances or improvements we are funding are lease incentives, then we commence revenue recognition when possession or control of the space is turned over to the tenant. Rental income from leases is recognized on a straight-line basis.
We record lease termination fees when a tenant has executed a definitive termination agreement with us and the payment of the termination fee is not subject to any material conditions that must be met or waived before the fee is due to us.
General Contractor and Service Fee Revenue
Management fees are based on a percentage of rental receipts of properties managed and are recognized as the rental receipts are collected. Maintenance fees are based upon established hourly rates and are recognized as the services are performed. Construction management and development fees represent fee-based third-party contracts and are recognized as earned based on the percentage of completion method.
We recognize income on construction contracts where we serve as a general contractor on the percentage of completion method. Using this method, profits are recorded based on our estimates of the percentage of completion of individual contracts, commencing when the work performed under the contracts reaches a point where the final costs can be estimated with reasonable accuracy. The percentage of completion estimates are based on a comparison of the contract expenditures incurred to the estimated final costs. Changes in job performance, job conditions and estimated profitability may result in revisions to costs and income and are recognized in the period in which the revisions are determined. To the extent that a fixed-price contract is estimated to result in a loss, the loss is recorded immediately.
Unbilled and overbilled receivables on construction contracts totaled $9.9 million and $7.8 million, respectively, at December 31, 2013 and $18.4 million and $2.4 million, respectively, at December 31, 2012. Overbilled receivables are included in other liabilities in the Consolidated Balance Sheets.
Property Sales
Gains on sales of all properties are recognized in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 360-20. The specific timing of the sale of a building is measured against various criteria in FASB ASC 360-20 related to the terms of the transactions and any continuing involvement in the form of management or financial assistance from the seller associated with the properties. We make judgments based on the specific terms of each transaction as to the amount of the total profit from the transaction that we recognize considering factors such as continuing ownership interest we may have with the buyer ("partial sales") and our level of future involvement with the property or the buyer that acquires the assets. If the full accrual sales criteria are not met, we defer gain recognition and account for the continued operations of the property by applying the finance, installment or cost recovery methods, as appropriate, until the full accrual sales criteria are met. Estimated future costs to be incurred after completion of each sale are included in the determination of the gain on sales.
To the extent that a property has had operations prior to sale, and that we do not have continuing involvement with the property, gains from sales of depreciated property are included in discontinued operations and the proceeds from the sale of these held-for-rental properties are classified in the investing activities section of the Consolidated Statements of Cash Flows.
Rental properties that do not meet the criteria for presentation as discontinued operations are classified as gain on sale of properties in the Consolidated Statements of Operations and Comprehensive Income.
Net Income (Loss) Per Common Share or Common Unit
Basic net income (loss) per common share or Common Unit is computed by dividing net income (loss) attributable to common shareholders or common unitholders, less dividends or distributions on share-based awards expected to vest (referred to as "participating securities" and primarily composed of unvested restricted stock units), by the weighted average number of common shares or Common Units outstanding for the period.
Diluted net income (loss) per common share is computed by dividing the sum of basic net income (loss) attributable to common shareholders and the noncontrolling interest in earnings allocable to Limited Partner Units (to the extent the Limited Partner Units are dilutive) by the sum of the weighted average number of common shares outstanding and, to the extent they are dilutive, Units outstanding and any potential dilutive securities for the period. Diluted net income (loss) per Common Unit is computed by dividing the basic net income (loss) attributable to common unitholders by the sum of the weighted average number of Common Units outstanding and any potential dilutive securities for the period.
The following table reconciles the components of basic and diluted net income (loss) per common share or Common Unit (in thousands):

Other Comprehensive Income
In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-02, Other Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income ("ASU 2013-02"), which was effective for us beginning with the three months ended March 31, 2013. ASU 2013-02 requires presentation of significant amounts reclassified out of accumulated other comprehensive income. Activity within other comprehensive income or loss includes the amortization to interest expense, over the lives of previously hedged loans, of the values of interest rate swaps that have been settled, as well as changes in the fair values of currently outstanding interest rate swaps that we have designated as cash flow hedges. Activity within other comprehensive income is not material for any individual type of activity, as well as for all activities in the aggregate, for all periods presented in this Report.
Federal Income Taxes
General Partner
The General Partner has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended. To qualify as a REIT, the General Partner must meet a number of organizational and operational requirements, including a requirement to distribute at least 90% of its REIT taxable income to its shareholders. Management intends to continue to adhere to these requirements and to maintain the General Partner's REIT status. As a REIT, the General Partner is entitled to a tax deduction for the dividends it pays to shareholders. Accordingly, the General Partner generally will not be subject to federal income taxes as long as it currently distributes to shareholders an amount equal to or in excess of its taxable income. The General Partner is also generally subject to federal income taxes on any taxable income that is not currently distributed to its shareholders. If the General Partner fails to qualify as a REIT in any taxable year, it will be subject to federal income taxes and may not be able to qualify as a REIT for four subsequent taxable years.
REIT qualification reduces, but does not eliminate, the amount of state and local taxes we pay. In addition, our financial statements include the operations of taxable corporate subsidiaries that are not entitled to a dividends paid deduction and are subject to federal, state and local income taxes. As a REIT, the General Partner may also be subject to certain federal excise taxes if it engages in certain types of transactions.
The following table reconciles the General Partner's net income (loss) to taxable income (loss) before the dividends paid deduction, and subject to the 90% distribution requirement, for the years ended December 31, 2013, 2012 and 2011 (in thousands):
	2013				2012				2011
Net income (loss)	$	196,549			$	(75,868	)		$	96,309

	100	%		100	%		100	%
Partnership
For the Partnership, the allocated share of income and loss other than the operations of its taxable REIT subsidiary is included in the income tax returns of its partners; accordingly the only federal income taxes included in the accompanying consolidated financial statements of the Partnership are in connection with its taxable REIT subsidiary.
Deferred Tax Assets
A full valuation allowance for the deferred tax assets of the taxable REIT subsidiary was maintained for 2013, 2012 and 2011.  Based on the level of historical taxable income and projections of taxable income under our current operating strategy, management believes that it is more likely than not that the taxable REIT subsidiary will not generate sufficient taxable income to realize any of its deferred tax assets.  Income taxes are not material to our operating results or financial position. Our taxable REIT subsidiary has no significant net deferred income tax positions or unrecognized tax benefit items.
Cash Paid for Income Taxes
We paid state and local income taxes of $830,000, $580,000 and $340,000 in 2013, 2012 and 2011, respectively.
Fair Value Measurements
We follow the framework established under accounting standard FASB ASC 820 for measuring fair value of non-financial assets and liabilities that are not required or permitted to be measured at fair value on a recurring basis but only in certain circumstances, such as a business combination.
Assets and liabilities recorded at fair value on the consolidated balance sheets are categorized based on the inputs to the valuation techniques as follows:
Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities to which we have access.
Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates and yield curves that are observable at commonly quoted intervals.
Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity's own assumptions, as there is little, if any, related market activity.
In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.
Use of Estimates
The preparation of the financial statements requires management to make a number of estimates and assumptions that affect the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. The most significant estimates, as discussed within our Summary of Significant Accounting Policies, pertain to the critical assumptions utilized in testing real estate assets for impairment, estimating the fair value of real estate assets when an impairment event has taken place and allocating the purchase price of acquired properties to tangible and intangible assets based on their respective fair values. Actual results could differ from those estimates.

	Significant Acquisitions and Dispositions
	Acquisitions and dispositions for the periods presented were completed in accordance with our strategy to reposition our investment concentration among product types and further diversify our geographic presence. With the exception of certain properties that have been sold or classified as held for sale, the results of operations for all acquired properties have been included in continuing operations within our consolidated financial statements since their respective dates of acquisition.
	2013 Acquisitions
	We acquired 17 operating properties during the year ended December 31, 2013. These acquisitions consisted of one industrial property in South Florida, one industrial property in Chicago, Illinois, three industrial properties in Central and Southern New Jersey, three industrial properties in Southern California, two industrial properties in Central California, one industrial property in Houston, Texas, one industrial property near Kansas City, Missouri, one industrial property near St. Louis, Missouri, two industrial properties in Northeast and Central Pennsylvania, one industrial property near Indianapolis, Indiana and one medical office property in Central Florida. The following table summarizes the fair value of amounts recognized for each major class of asset and liability (in thousands) for these acquisitions:
	Real estate assets	$	488,294
	Lease-related intangible assets	67,167
	Total acquired assets	555,461
	Secured debt	103,638
	Below market lease liability	2,153
	Other liabilities	2,201
	Total assumed liabilities	107,992
	Fair value of acquired net assets	$	447,469
	The leases in the acquired properties had a weighted average remaining life at acquisition of approximately 7.9 years.
	We have included $24.7 million in rental revenues, $1.4 million in rental expenses and $3.6 million in real estate taxes in continuing operations during 2013 for these properties since their respective dates of acquisition.
	2012 Acquisitions
	We acquired 37 operating properties during the year ended December 31, 2012. These acquisitions consisted of three industrial properties near Chicago, Illinois, two industrial properties in Columbus, Ohio, one industrial property in Southern California, two industrial properties in Northern California, one industrial property in Atlanta, Georgia, one industrial property in Houston, Texas and 27 medical office properties in various markets. The following table summarizes our allocation of the fair value of amounts recognized for each major class of asset and liability (in thousands) for these acquisitions:
	Real estate assets	$	668,149
	Lease-related intangible assets	111,509
	Other assets	5,714
	Total acquired assets	785,372
	Secured debt	100,826
	Other liabilities	11,928
	Total assumed liabilities	112,754
	Fair value of acquired net assets	$	672,618
	The leases in the acquired properties had a weighted average remaining life at acquisition of approximately 8.8 years.
	We have included $28.5 million in rental revenues, $3.6 million in rental expenses and $3.8 million in real estate taxes in continuing operations during 2012 for these properties since their respective dates of acquisition.
	Fair Value Measurements
	The fair value estimates used in allocating the aggregate purchase price of each acquisition among the individual components of real estate assets and liabilities were determined primarily through calculating the "as-if vacant" value of each building, using the income approach, and relied significantly upon internally determined assumptions. We have determined these estimates to have been primarily based upon Level 3 inputs, which are unobservable inputs based on our own assumptions. The range of most significant assumptions utilized in making the lease-up and future disposition estimates used in calculating the "as-if vacant" value of each building acquired during 2013 and 2012 are as follows:
		2013		2012
		Low	High	Low	High
	Discount rate	6.49%	9.67%	7.13%	10.78%
	Exit capitalization rate	5.09%	7.67%	5.75%	8.88%
	Lease-up period (months)	12	24	6	36
	Net rental rate per square foot - Industrial	$2.90	$8.28	$2.75	$7.62
	Net rental rate per square foot - Medical Office	$18.00	$18.00	$13.20	$26.14
	Acquisition-Related Activity
	The acquisition-related activity in our consolidated Statements of Operations and Comprehensive Income consisted of transaction costs for completed acquisitions, which are expensed as incurred, as well as gains or losses related to acquisitions where we had a pre-existing non-controlling ownership interest. Acquisition-related activity for the years ended December 31, 2013, 2012 and 2011 includes transaction costs of $4.1 million, $4.2 million and $2.3 million, respectively. In 2013 and 2011, we recognized gains of $962,000 and $1.1 million, respectively, related to acquisitions of properties from unconsolidated joint ventures.
	Dispositions
	We disposed of income-producing real estate assets and undeveloped land and received net cash proceeds of $740.0 million, $138.1 million and $1.57 billion in 2013, 2012 and 2011, respectively.
	Included in the building dispositions in 2013 is the sale of 18 medical office properties in various markets, which totaled 1.1 million square feet and were sold for $285.9 million. The properties sold were in markets, or were associated with health systems, where we did not believe there to be significant future growth potential.
	During the year ended December 31, 2013, 19 office properties and one industrial property were sold from certain of our unconsolidated joint ventures for which our capital distributions totaled $92.3 million. Our share of gains from joint venture property sales, which are included in equity in earnings, related almost entirely to these sales and totaled $51.2 million.
	Included in the building dispositions in 2011 is the sale of substantially all of our wholly-owned suburban office real estate properties in Atlanta, Chicago, Columbus, Dallas, Minneapolis, Orlando and Tampa, consisting of 79 buildings that had an aggregate of 9.8 million square feet, to affiliates of Blackstone Real Estate Partners. The sales price was approximately $1.06 billion which, after settlement of certain working capital items and the payment of applicable transaction costs, was received in a combination of approximately $1.02 billion in cash and the assumption by the buyer of mortgage debt with a face value of approximately $24.9 million.
	Also included in the building dispositions in 2011 is the sale of 13 suburban office buildings, totaling over 2.0 million square feet, to an existing 20%-owned unconsolidated joint venture. These buildings were sold to the unconsolidated joint venture for an agreed value of $342.8 million, of which our 80% share of proceeds totaled $273.7 million.
	All other dispositions were not individually material.

	(1) Differences between the net investment in our unconsolidated joint ventures and our underlying equity in the net assets of the ventures are primarily a result of previous impairments related to our investment in the unconsolidated joint ventures, basis differences associated with the sales of properties to joint ventures in which we retained an ownership interest and loans we have made to the joint ventures. These adjustments have resulted in an aggregate difference reducing our investments in unconsolidated joint ventures by $4.2 million and $15.2 million as of December 31, 2013 and 2012, respectively. Differences between historical cost basis and the basis reflected at the joint venture level (other than loans and impairments) are typically depreciated over the life of the related asset.

	We allocate interest expense to discontinued operations and have included such interest expense in computing income from discontinued operations. Interest expense allocable to discontinued operations includes interest on any secured debt for properties included in discontinued operations and an allocable share of our consolidated unsecured interest expense for unencumbered properties. The allocation of unsecured interest expense to discontinued operations was based upon the gross book value of the unencumbered real estate assets included in discontinued operations as it related to the total gross book value of our unencumbered real estate assets.

Indebtedness	'
	Indebtedness
	All debt is held directly or indirectly by the Partnership. The General Partner itself does not have any indebtedness, but does guarantee the unsecured debt of the Partnership.
	Indebtedness at December 31, 2013 and 2012 consists of the following (in thousands):
		Maturity Date		Weighted Average Interest Rate			Weighted Average Interest Rate
				2013			2012			2013		2012

	Secured Debt
	At December 31, 2013, our secured debt was collateralized by rental properties with a carrying value of $1.9 billion and by letters of credit in the amount of $4.4 million.
	The fair value of our fixed rate secured debt at December 31, 2013 was $1.1 billion. Because our fixed rate secured debt is not actively traded in any marketplace, we utilized a discounted cash flow methodology to determine its fair value. Accordingly, we calculated fair value by applying an estimate of the current market rate to discount the debt's remaining contractual cash flows. Our estimate of a current market rate, which is the most significant input in the discounted cash flow calculation, is intended to replicate debt of similar maturity and loan-to-value relationship. The estimated rates ranged from 3.90% to 5.30%, depending on the attributes of the specific loans. The current market rates we utilized were internally estimated; therefore, we have concluded that our determination of fair value for our fixed rate secured debt was primarily based upon Level 3 inputs.
	We assumed three secured loans in conjunction with our acquisition activity in 2013. These assumed loans had a total face value of $99.3 million and a fair value of $103.6 million. These assumed loans had a weighted average remaining term at acquisition of 1.8 years and carry a weighted average stated interest rate of 5.59%. We used an estimated market interest rate of 3.00% in determining the fair value of these loans. Between the date of acquisition and the end of the most recent reporting period, interest rates increased, resulting in our estimated market interest rate for these loans increasing to 3.90%.
	We assumed nine secured loans in conjunction with our acquisition activity in 2012. These assumed loans had a total face value of $96.1 million and fair value of $100.8 million. These assumed loans carry a weighted average stated interest rate of 5.56% and had a weighted average remaining term at acquisition of 2.4 years. We used an estimated market rate of 3.50% in determining the fair value of these loans.
	In 2012, a newly formed subsidiary, consolidated by both the General Partner and the Partnership, borrowed $13.3 million on a secured note bearing interest at a variable rate of LIBOR plus 2.50% (equal to 2.67% for outstanding borrowings as of December 31, 2013) and maturing June 29, 2017.
	During the year ended December 31, 2013, we repaid twelve secured loans, at their maturity dates, totaling $153.8 million. These loans had a weighted average stated interest rate of 5.52%.
	During the year ended December 31, 2012, we repaid five secured loans at their maturity dates totaling $102.1 million. These loans had a weighted average stated interest rate of 6.08%.
	Unsecured Debt
	At December 31, 2013, with the exception of the $250.0 million variable rate term note described below, all of our unsecured debt bore interest at fixed rates and primarily consisted of unsecured notes that are publicly traded. We utilized broker estimates in estimating the fair value of our fixed rate unsecured debt. Our unsecured notes are thinly traded and, in certain cases, the broker estimates were not based upon comparable transactions. The broker estimates took into account any recent trades within the same series of our fixed rate unsecured debt, comparisons to recent trades of other series of our fixed rate unsecured debt, trades of fixed rate unsecured debt from companies with profiles similar to ours, as well as overall economic conditions. We reviewed these broker estimates for reasonableness and accuracy, considering whether the estimates were based upon market participant assumptions within the principal and most advantageous market and whether any other observable inputs would be more accurate indicators of fair value than the broker estimates. We concluded that the broker estimates were representative of fair value. We have determined that our estimation of the fair value of our fixed rate unsecured debt was primarily based upon Level 3 inputs, as defined. The estimated trading values of our fixed rate unsecured debt, depending on the maturity and coupon rates, ranged from 92.00% to 124.00% of face value.
	We utilize a discounted cash flow methodology in order to estimate the fair value of our variable rate term loan. The net present value of the difference between future contractual interest payments and future interest payments based on our estimate of a current market rate represents the difference between the book value and the fair value. Our estimate of a current market rate was based on estimated market spreads and the quoted yields on federal government treasury securities with similar maturity dates.
	We took the following actions during 2013 and 2012 as it pertains to our unsecured indebtedness:
	•	In December 2013, we issued $250.0 million of unsecured notes that bear interest at 3.875%, have an effective rate of 3.91%, and mature on February 15, 2021.
	•	During the year ended December 31, 2013, we repaid three unsecured notes totaling $675.0 million. These notes had a weighted average effective rate of 6.37% and a weighted average stated rate of 5.57%. An unsecured note was repaid prior to its maturity date, and we incurred a loss on extinguishment of $9.4 million, which related to a make-whole payment to the bondholders as well as the write-off of unamortized deferred financing costs.
	•	In May 2013, we issued and fully drew down on a term loan with an aggregate commitment of $250.0 million that bears interest at a variable rate of LIBOR plus 1.35% (equal to 1.52% for outstanding borrowings at December 31, 2013) and matures May 14, 2018.
	•	In March 2013, we issued $250.0 million of unsecured notes that bear interest at 3.625%, have an effective rate of 3.72%, and mature on April 15, 2023.
	•	In October 2012, we repaid $50.0 million of medium term notes, which had an effective interest rate of 5.45%, at their scheduled maturity date.
	•	In September 2012, we issued $300.0 million of unsecured notes that bear interest at 3.875%, have an effective rate of 3.925%, and mature on October 15, 2022.
	•	In August 2012, we repaid $150.0 million of senior unsecured notes, which had an effective interest rate of 6.01%, at their scheduled maturity date.
	•	In July 2012, one of our consolidated subsidiaries repaid $21.0 million of variable rate unsecured debt, which bore interest at a rate of LIBOR plus 0.85%, at its scheduled maturity date.
	•	In June 2012, we issued $300.0 million of senior unsecured notes that bear interest at 4.375%, have an effective rate of 4.466% and mature on June 15, 2022.
	The indentures (and related supplemental indentures) governing our outstanding series of notes also require us to comply with financial ratios and other covenants regarding our operations. We were in compliance with all such covenants at December 31, 2013.
	Unsecured Line of Credit
	Our unsecured line of credit at December 31, 2013 is described as follows (in thousands):
								Outstanding Balance at
	Description	Borrowing Capacity				Maturity Date		December 31, 2013
	Unsecured Line of Credit – Partnership	$	850,000			Dec-15		$	88,000
	The Partnership's unsecured line of credit has an interest rate on borrowings of LIBOR plus 1.25% (equal to 1.42% for borrowings at December 31, 2013) and a maturity date of December 2015. Subject to certain conditions, the terms also include an option to increase the facility by up to an additional $400.0 million, for a total of up to $1.25 billion.
	This line of credit provides us with an option to obtain borrowings from financial institutions that participate in the line at rates that may be lower than the stated interest rate, subject to certain restrictions.
	This line of credit contains financial covenants that require us to meet certain financial ratios and defined levels of performance, including those related to total fixed charge coverage, unsecured interest expense coverage and debt-to-asset value (with asset value being defined in the Partnership's unsecured line of credit agreement). At December 31, 2013, we were in compliance with all covenants under this line of credit.
	To the extent that there are outstanding borrowings, we utilize a discounted cash flow methodology in order to estimate the fair value of our unsecured line of credit. The net present value of the difference between future contractual interest payments and future interest payments based on our estimate of a current market rate represents the difference between the book value and the fair value. Our estimate of a current market rate was based on estimated market spreads and the quoted yields on federal government treasury securities with similar maturity dates. The current market rate of 1.47% that we utilized was internally estimated; therefore, we have concluded that our determination of fair value for our unsecured line of credit was primarily based upon Level 3 inputs.
	Through July 2012, a consolidated subsidiary had an unsecured line of credit that allowed for borrowings up to $30.0 million and bore interest at a rate of LIBOR plus 0.85%. This unsecured line of credit was used to fund development activities within the consolidated subsidiary and the outstanding balance of $20.3 million was repaid at its maturity in July 2012.
	Changes in Fair Value
	As all of our fair value debt disclosures relied primarily on Level 3 inputs, the following table summarizes the book value and changes in the fair value of our debt for the year ended December 31, 2013 (in thousands):

Segment Reporting	'
	Segment Reporting
	We have four reportable operating segments at December 31, 2013, the first three of which consist of the ownership and rental of (i) industrial, (ii) office and (iii) medical office real estate investments. The operations of our industrial, office and medical office properties, along with our retail properties, are collectively referred to as "Rental Operations." Our retail properties, as well as any other properties not included in our reportable segments, do not by themselves meet the quantitative thresholds for separate presentation as a reportable segment. The fourth reportable segment consists of various real estate services such as property management, asset management, maintenance, leasing, development, general contracting and construction management to third-party property owners and joint ventures, and is collectively referred to as "Service Operations." Our reportable segments offer different products or services and are managed separately because each segment requires different operating strategies and management expertise.
	We assess and measure the overall operating results of the General Partner and the Partnership based upon Funds From Operations ("FFO"), as defined by the National Association of Real Estate Investment Trusts ("NAREIT"). FFO is an industry performance measure that management believes is a useful indicator of consolidated operating performance. FFO is used by industry analysts and investors as a supplemental operating performance measure of a REIT. NAREIT created FFO as a non-GAAP supplemental measure of REIT operating performance. FFO, as defined by NAREIT, represents GAAP net income (loss), excluding extraordinary items as defined under GAAP, gains or losses from sales of previously depreciated real estate assets, impairment charges related to depreciable real estate assets, plus certain non-cash items such as real estate asset depreciation and amortization, and after similar adjustments for unconsolidated partnerships and joint ventures. The most comparable GAAP measure is net income (loss) attributable to common shareholders or common unitholders. FFO attributable to common shareholders or common unitholders should not be considered as a substitute for net income (loss) attributable to common shareholders or common unitholders or any other measures derived in accordance with GAAP and may not be comparable to other similarly titled measures of other companies.
	Historical cost accounting for real estate assets in accordance with GAAP implicitly assumes that the value of real estate assets diminishes predictably over time. Since real estate values instead have historically risen or fallen with market conditions, many industry analysts and investors have considered presentation of operating results for real estate companies that use historical cost accounting to be insufficient by themselves. Management believes that the use of FFO attributable to common shareholders or common unitholders, combined with net income (which remains the primary measure of performance), improves the understanding of operating results of REITs among the investing public and makes comparisons of REIT operating results more meaningful. Management believes that the use of FFO as a performance measure enables investors and analysts to readily identify the operating results of the long-term assets that form the core of a REIT's activity and assist them in comparing these operating results between periods or between different companies.
	Other revenue consists of other operating revenues not identified with one of our operating segments. We do not allocate interest expense and certain other non-property specific revenues and expenses ("Non-Segment Items," as shown in the table below) to our individual operating segments in determining our performance measure. Thus, the operational performance measure presented here on a segment-level basis represents net earnings, excluding depreciation expense and the Non-Segment Items not allocated, and is not meant to present FFO as defined by NAREIT.
	The following table shows (i) the revenues for each of the reportable segments and (ii) a reconciliation of FFO attributable to common shareholders or common unitholders to net income (loss) attributable to common shareholders or common unitholders for the years ended December 31, 2013, 2012 and 2011 (in thousands):

Shareholders' Equity	'
	Shareholders' Equity of the General Partner and Partners' Capital of the Partnership
	General Partner
	The General Partner periodically uses the public equity markets to fund the development and acquisition of additional rental properties or to pay down debt. The proceeds of these offerings are contributed to the Partnership in exchange for an additional interest in the Partnership.
	In January 2013, the General Partner completed a public offering of 41.4 million common shares at an issue price of $14.25 per share, resulting in gross proceeds of $590.0 million and, after deducting underwriting fees and estimated offering costs, net proceeds of approximately $571.9 million. A portion of the net proceeds from this offering were used to repay all of the outstanding borrowings under the Partnership's existing revolving credit facility, which had an outstanding balance of $285.0 million at December 31, 2012, and the remaining proceeds were used to redeem all of the General Partner's outstanding 8.375% Series O Cumulative Redeemable Preferred Shares ("Series O Shares") and for general corporate purposes.
	Throughout 2013, the General Partner issued 4.8 million shares of common stock pursuant to its at the market equity program, generating gross proceeds of approximately $79.3 million and, after deducting commissions and other costs, net proceeds of approximately $77.8 million. The proceeds from these offerings were used for general corporate purposes, which include the funding of development costs.
	In February 2013, the General Partner redeemed all of the outstanding shares of its Series O Shares at their liquidation amount of $178.0 million. Original offering costs of $5.9 million were included as a reduction to net income attributable to common shareholders in conjunction with the redemption of these shares.
	Throughout 2012, the General Partner issued 22.7 million shares of common stock pursuant to its at the market equity program, generating gross proceeds of approximately $322.2 million and, after considering commissions and other costs, net proceeds of approximately $315.3 million. The proceeds from these offerings were used for acquisitions, general corporate purposes and redemption of preferred shares and fixed rate secured debt
	In March 2012, the General Partner redeemed all of the outstanding shares of its 6.950% Series M Cumulative Redeemable Preferred Shares at a liquidation amount of $168.3 million. Offering costs of $5.7 million were included as an increase to net loss attributable to common shareholders in conjunction with the redemption of these shares.
	In July 2011, the General Partner redeemed all of the outstanding shares of its 7.250% Series N Cumulative Redeemable Preferred Shares at a liquidation amount of $108.6 million. Offering costs of $3.6 million were included as a reduction to net income attributable to common shareholders in conjunction with the redemption of these shares.
	In February 2011, the General Partner repurchased 80,000 shares of its Series O Shares. The Series O Shares that were repurchased had a total redemption value of $2.0 million and were repurchased for $2.1 million. An adjustment of approximately $163,000, which included a ratable portion of original issuance costs, was included as a reduction to net income attributable to common shareholders.
	The following series of preferred shares were outstanding as of December 31, 2013 (in thousands, except percentage data):
	Description	Shares	Dividend		Optional	Liquidation
		Outstanding	Rate		Redemption	Preference
					Date
	Series J Preferred	396	6.625	%	August 29, 2008	$99,058
	Series K Preferred	598	6.5	%	February 13, 2009	$149,550
	Series L Preferred	796	6.6	%	November 30, 2009	$199,075
	All series of preferred shares require cumulative distributions and have no stated maturity date (although the General Partner may redeem all such preferred shares on or following their optional redemption dates at its option, in whole or in part).
	Partnership
	For each common share or preferred share that the General Partner issues, the Partnership issues a corresponding General Partner Unit or Preferred Unit, as applicable, to the General Partner in exchange for the contribution of the proceeds from the stock issuance. Similarly, when the General Partner redeems or repurchases common shares or preferred shares, the Partnership redeems the corresponding Common Units or Preferred Units held by the General Partner at the same price.

Stock Based Compensation	'
	Stock Based Compensation
	We are authorized to issue up to 9.7 million shares of the General Partner's common stock under our stock-based employee and non-employee compensation plans.
	Restricted Stock Units
	Under our 2005 Long-Term Incentive Plan and our 2005 Non-Employee Directors Compensation Plan (collectively, the "Compensation Plans") approved by the General Partner's shareholders in April 2005, RSUs may be granted to non-employee directors, executive officers and selected management employees. A RSU is economically equivalent to a share of the General Partner's common stock.
	RSUs granted to employees generally vest 20% per year over five years, have contractual lives of five years and are payable in shares of our common stock with a new share of such common stock issued upon each RSU's vesting. RSUs granted to existing non-employee directors vest 100% over one year, and have contractual lives of one year.
	To the extent that a recipient of a RSU grant is not determined to be retirement eligible, as defined by the Compensation Plans, we recognize expense on a straight-line basis over the vesting period. Expense is recognized immediately at the date of grant to the extent a recipient is retirement eligible and expense is accelerated to the extent that a participant will become retirement eligible prior to the end of the contractual life of granted RSUs.
	The following table summarizes transactions for our RSUs, excluding dividend equivalents, for 2013:
	Restricted Stock Units	Number of		Weighted
		RSUs		Average
				Grant Date
				Fair Value
	RSUs at December 31, 2012	2,680,765		$12.26
	Granted	834,435		$16.32
	Vested	(974,476	)	$12.00
	Forfeited	(196,043	)	$13.47
	RSUs at December 31, 2013	2,344,681		$13.71
	Compensation cost recognized for RSUs totaled $13.3 million, $11.5 million and $11.2 million for the years ended December 31, 2013, 2012 and 2011, respectively.
	As of December 31, 2013, there was $12.7 million of total unrecognized compensation expense related to nonvested RSUs granted under the Plan, which is expected to be recognized over a weighted average period of 2.9 years.

	We are exposed to capital market risk, such as changes in interest rates. In an effort to manage interest rate risk, we may enter into interest rate hedging arrangements from time to time. We do not utilize derivative financial instruments for trading or speculative purposes.
	The effectiveness of our hedges is evaluated throughout their lives using the hypothetical derivative method under which the change in fair value of the actual swap designated as the hedging instrument is compared to the change in fair value of a hypothetical swap. We had no material interest rate derivatives, when considering the fair value of the hedging instruments, in any period presented.

	Commitments and Contingencies
	We have guaranteed the repayment of $76.2 million of economic development bonds issued by various municipalities in connection with certain commercial developments. We will be required to make payments under our guarantees to the extent that incremental taxes from specified developments are not sufficient to pay the bond debt service. Management does not believe that it is probable that we will be required to make any significant payments in satisfaction of these guarantees.
	We also have guaranteed the repayment of secured and unsecured loans of four of our unconsolidated subsidiaries. At December 31, 2013, the maximum guarantee exposure for these loans was approximately $188.4 million.
	We lease certain land positions with terms extending to October 2105, with a total future payment obligation of $215.4 million. No payments on these ground leases, which are classified as operating leases, are material in any individual year.
	We are subject to various legal proceedings and claims that arise in the ordinary course of business. In the opinion of management, the amount of any ultimate liability with respect to these actions will not materially affect our consolidated financial statements or results of operations.
	We own certain parcels of land that are subject to special property tax assessments levied by quasi municipal entities. To the extent that such special assessments are fixed and determinable, the discounted value of the full assessment is recorded as a liability. We have $12.4 million of such special assessment liabilities, which are included within other liabilities on our consolidated balance sheet as of December 31, 2013.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Consolidation, Policy	'
	Principles of Consolidation
	The consolidated financial statements include our accounts and the accounts of our majority-owned or controlled subsidiaries. The equity interests in these controlled subsidiaries not owned by us are reflected as noncontrolling interests in the consolidated financial statements. All significant intercompany balances and transactions have been eliminated in the consolidated financial statements. Investments in entities that we do not control, and variable interest entities ("VIEs") in which we are not the primary beneficiary, are not consolidated and are reflected as investments in unconsolidated companies under the equity method of reporting.
Reclassifications	'
	Reclassifications
	Certain amounts in the accompanying consolidated financial statements for 2012 and 2011 have been reclassified to conform to the 2013 consolidated financial statement presentation.
Real Estate, Policy	'
	.
	Real Estate Investments
	Rental real property, including land, land improvements, buildings and tenant improvements, are included in real estate investments and are generally stated at cost. Construction in process and undeveloped land are included in real estate investments and are stated at cost. Real estate investments also include our equity interests in unconsolidated joint ventures that own and operate rental properties and hold land for development.
	Depreciation
	Buildings and land improvements are depreciated on the straight-line method over their estimated lives not to exceed 40 and 15 years, respectively, for properties that we develop, and not to exceed 30 and 10 years, respectively, for acquired properties. Tenant improvement costs are depreciated using the straight-line method over the shorter of the useful life of the asset or term of the related lease.
	Cost Capitalization
	Direct and certain indirect costs clearly associated with the development, construction, leasing or expansion of real estate investments are capitalized as a cost of the property. In addition, all leasing commissions paid to third parties for new leases or lease renewals are capitalized. We capitalize a portion of our indirect costs associated with our construction, development and leasing efforts. In assessing the amount of direct and indirect costs to be capitalized, allocations are made based on estimates of the actual amount of time spent in each activity. We do not capitalize any costs attributable to downtime or to unsuccessful projects.
	We capitalize direct and indirect project costs associated with the initial construction of a property up to the time the property is substantially complete and ready for its intended use. In addition, we capitalize costs, including real estate taxes, insurance, and utilities, that have been allocated to vacant space based on the square footage of the portion of the building not held available for immediate occupancy during the extended lease-up periods after construction of the building shell has been completed if costs are being incurred to ready the vacant space for its intended use. If costs and activities incurred to ready the vacant space cease, then cost capitalization is also discontinued until such activities are resumed. Once necessary work has been completed on a vacant space, project costs are no longer capitalized.
	We cease capitalization of all project costs on extended lease-up periods when significant activities have ceased, which does not exceed the shorter of a one-year period after the completion of the building shell or when the property attains 90% occupancy.
	Impairment
	We evaluate our real estate assets, with the exception of those that are classified as held-for-sale, for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If such an evaluation is considered necessary, we compare the carrying amount of that real estate asset, or asset group, with the expected undiscounted cash flows that are directly associated with, and that are expected to arise as a direct result of, the use and eventual disposition of that asset, or asset group. Our estimate of the expected future cash flows used in testing for impairment is based on, among other things, our estimates regarding future market conditions, rental rates, occupancy levels, costs of tenant improvements, leasing commissions and other tenant concessions, assumptions regarding the residual value of our properties at the end of our anticipated holding period and the length of our anticipated holding period and is, therefore, subjective by nature. These assumptions could differ materially from actual results. If our strategy changes or if market conditions otherwise dictate a reduction in the holding period and an earlier sale date, an impairment loss could be recognized and such loss could be material. To the extent the carrying amount of a real estate asset, or asset group, exceeds the associated estimate of undiscounted cash flows, an impairment loss is recorded to reduce the carrying value of the asset to its fair value.
	The determination of the fair value of real estate assets is also highly subjective, especially in markets where there is a lack of recent comparable transactions. We primarily utilize the income approach to estimate the fair value of our income producing real estate assets. We utilize marketplace participant assumptions to estimate the fair value of a real estate asset when an impairment charge is required to be measured. The estimation of future cash flows, as well as the selection of the discount rate and exit capitalization rate used in applying the income approach, are highly subjective measures in estimating fair value.
	Real estate assets classified as held-for-sale are reported at the lower of their carrying value or their fair value, less estimated costs to sell. Once a property is designated as held-for-sale, no further depreciation expense is recorded.
	Purchase Accounting
	We expense acquisition related costs immediately as period costs. We record assets acquired in step acquisitions at their full fair value and record a gain or loss, within acquisition-related activity in our consolidated Statements of Operations, for the difference between the fair value and the carrying value of our existing equity interest. Additionally, contingencies arising from a business combination are recorded at fair value if the acquisition date fair value can be determined during the measurement period.
	We allocate the purchase price of acquired properties to tangible and identified intangible assets based on their respective fair values, using all pertinent information available at the date of acquisition. The allocation to tangible assets (buildings, tenant improvements and land) is based upon management's determination of the value of the property as if it were vacant. This “as-if vacant” value is estimated using an income, or discounted cash flow, approach that relies upon internally determined assumptions that we believe are consistent with current market conditions for similar properties. The most important assumptions in determining the allocation of the purchase price to tangible assets are the exit capitalization rate, discount rate, estimated market rents, and hypothetical expected lease-up periods. The purchase price of real estate assets is also allocated to intangible assets consisting of the above or below market component of in-place leases, the value of in-place leases as well as, to the extent applicable, acquired in-place leases that may have a customer relationship intangible value. There have been no customer relationship intangible assets related to any of our acquisitions to date.
	The value allocable to the above or below market component of an acquired in-place lease is determined based upon the present value (using a discount rate which reflects the risks associated with the acquired leases) of the difference between (i) the contractual amounts to be received pursuant to the lease over its remaining term and (ii) management's estimate of the amounts that would be received using fair market rates over the remaining term of the lease. The amounts allocated to above market leases are included in deferred leasing and other costs in the balance sheet and below market leases are included in other liabilities in the balance sheet; both are amortized to rental income over the remaining terms of the respective leases.
	Factors considered in determining the value allocable to in-place leases include estimates, during hypothetical expected lease-up periods, of space that is actually leased at the time of acquisition, of lost rent at market rates, fixed operating costs that will be recovered from tenants, and theoretical leasing commissions required to execute similar leases. These intangible assets are included in deferred leasing and other costs in the balance sheet and are depreciated over the remaining term of the existing lease.
Joint Ventures Policy	'
	Joint Ventures
	We have equity interests in unconsolidated joint ventures that primarily own and operate rental properties or hold land for development. We consolidate those joint ventures that are considered to be VIEs where we are the primary beneficiary. We analyze our investments in joint ventures to determine if the joint venture is considered a VIE and would require consolidation. We (i) evaluate the sufficiency of the total equity investment at risk, (ii) review the voting rights and decision-making authority of the equity investment holders as a group and whether there are any guaranteed returns, protection against losses, or capping of residual returns within the group and (iii) establish whether activities within the venture are on behalf of an investor with disproportionately few voting rights in making this VIE determination.
	To the extent that we (i) are the sole entity that has the power to direct the activities of the VIE and (ii) have the obligation or rights to absorb the VIE's losses or receive its benefits, then we would be determined to be the primary beneficiary of the VIE and would consolidate it. At each reporting period, we re-assess our conclusions as to which, if any, party within the VIE is considered the primary beneficiary.
	At December 31, 2012, we had three unconsolidated joint ventures that met the criteria to be considered VIEs. In December 2013, one of those joint ventures sold assets and repaid all of its third-party debt, thus removing the subordinated financial support in the form of the guarantee of the joint venture's debt, which we had previously provided. As the result of these events, we re-evaluated the sufficiency of the joint venture's equity at risk and determined that it no longer met the criteria to be considered a VIE. As such, we evaluated the joint venture for consolidation under the voting interest model and determined that the equity method of accounting was still appropriate due to the fact that both we and our partner had substantive participating rights over the joint venture's operations.
	After the aforementioned reconsideration event, there were two unconsolidated joint ventures at December 31, 2013 that met the criteria to be considered VIEs. These two unconsolidated joint ventures were formed with the sole purpose of developing, constructing, leasing, marketing and selling or operating properties. The business activities of these unconsolidated joint ventures have been financed through a combination of equity contributions, partner/member loans, and third-party debt that is guaranteed by a combination of us and the other partner/member of each entity. All significant decisions for these unconsolidated joint ventures, including those decisions that most significantly impact each venture's economic performance, require unanimous approval of each joint venture's partners or members. In certain cases, these decisions also require lender approval. Unanimous approval requirements for these unconsolidated joint ventures include entering into new leases, setting annual operating budgets, selling underlying properties, and incurring additional indebtedness. Because no single entity exercises control over the decisions that most significantly affect each joint venture's economic performance, we determined there to be no individual primary beneficiary and that the equity method of accounting is appropriate.
	The following table provides a summary of the carrying value in our consolidated balance sheet, as well as our maximum loss exposure under guarantees for the unconsolidated subsidiaries that we have determined to be VIEs at December 31, 2013 and 2012, respectively (in millions):
		Carrying Value						Maximum Loss
								Exposure
		December 31, 2013			December 31, 2012			December 31, 2013			December 31, 2012
	Investment in unconsolidated companies	$	7.5		$	54.7		$	7.5		$	54.7
	Guarantee obligations (1)	$	(18.4	)	$	(23.3	)	$	(112.8	)	$	(144.8	)
	-1	We are party to guarantees of the third-party debt of these joint ventures, and our maximum loss exposure is equal to the maximum monetary obligation pursuant to the guarantee agreements. We have also recorded a liability for our probable future obligation under a guarantee to the lender of one of these ventures, which is included within the carrying value of our guarantee obligations. Pursuant to an agreement with the lender, we may make member loans to this joint venture that will reduce our maximum guarantee obligation, which is $13.4 million at December 31, 2013, on a dollar-for-dollar basis. The carrying value of our recorded guarantee obligations is included in other liabilities in our Consolidated Balance Sheets.
	To the extent that our joint ventures do not qualify as VIEs, they are consolidated if we control them through majority ownership interests or if we are the managing entity (general partner or managing member) and our partner does not have substantive participating rights. Control is further demonstrated by our ability to unilaterally make significant operating decisions, refinance debt and sell the assets of the joint venture without the consent of the non-managing entity and the inability of the non-managing entity to remove us from our role as the managing entity. Consolidated joint ventures that are not VIEs are not significant in any period presented in these consolidated financial statements.
	We use the equity method of accounting for those joint ventures where we exercise significant influence but do not have control. Under the equity method of accounting, our investment in each joint venture is included on our balance sheet; however, the assets and liabilities of the joint ventures for which we use the equity method are not included on our balance sheet.
	To the extent that we contribute assets to a joint venture, our investment in the joint venture is recorded at our cost basis in the assets that were contributed to the joint venture. To the extent that our cost basis is different than the basis reflected at the joint venture level, the basis difference is amortized over the life of the related asset and included in our share of equity in net income of the joint venture. We recognize gains on the contribution or sale of real estate to joint ventures, relating solely to the outside partner's interest, to the extent the economic substance of the transaction is a sale.
	When circumstances indicate there may have been a reduction in the value of an equity investment, we evaluate whether the loss in value is other than temporary. If we conclude it is other than temporary we recognize an impairment charge to reflect the equity investment at fair value.
Cash and Cash Equivalents, Policy	'
	Cash Equivalents
	Investments with an original maturity of three months or less are classified as cash equivalents.
Receivables, Policy	'
	Valuation of Receivables
	We reserve the entire receivable balance, including straight-line rent, of any tenant with an amount outstanding over 90 days. Additional reserves are recorded for more current amounts, as applicable, where we have determined collectability to be doubtful. Straight-line rent receivables for any tenant with long-term risk, regardless of the status of current rent receivables, are reviewed and reserved as necessary.
Deferred Charges, Policy	'
	Deferred Costs
	Costs incurred in connection with obtaining financing are deferred and are amortized to interest expense over the term of the related loan. All direct and indirect costs, including estimated internal costs, associated with the leasing of real estate investments owned by us are capitalized and amortized over the term of the related lease. We include lease incentive costs, which are payments made on behalf of a tenant to sign a lease, in deferred leasing costs and amortize them on a straight-line basis over the respective lease terms as a reduction of rental revenues. We include as lease incentives amounts funded to construct tenant improvements owned by the tenant. Unamortized costs are charged to expense upon the early termination of the lease or upon early payment of the financing.
	Deferred leasing and other costs at December 31, 2013 and 2012, excluding such costs for properties classified as held-for-sale, were as follows (in thousands):
		2013				2012

Debt, Policy	'
	Convertible Debt Accounting
	Our 3.75% Exchangeable Senior Notes ("Exchangeable Notes") were issued in November 2006 and had an exchange rate of 20.47 common shares per $1,000 principal amount of the notes, representing an exchange price of $48.85 per common share. We repaid the Exchangeable Notes at the first contractual redemption date in December 2011. We accounted for the debt and equity components of our Exchangeable Notes separately, with the value assigned to the debt component equal to the estimated fair value of debt with similar contractual cash flows, but without the conversion feature, resulting in the debt being recorded at a discount. The resulting debt discount was amortized over the period from its issuance through the date of repayment as additional non-cash interest expense.
	Interest expense was recognized on the Exchangeable Notes at an effective rate of 5.62%. The increase to interest expense (in thousands) on the Exchangeable Notes, which led to a corresponding decrease to net income, for the year ended December 31, 2011 is summarized as follows:
		2011
	Interest expense on Exchangeable Notes, excluding effect of accounting for convertible debt	$	5,769
	Effect of accounting for convertible debt	2,090
	Total interest expense on Exchangeable Notes	$	7,859
Noncontrolling Interests Policy	'
	Noncontrolling Interests
	Noncontrolling interests relate to the minority ownership interests in the Partnership and interests in consolidated property partnerships that are not wholly-owned by the General Partner or the Partnership. Noncontrolling interests are subsequently adjusted for additional contributions, distributions to noncontrolling holders and the noncontrolling holders' proportionate share of the net earnings or losses of each respective entity. We report noncontrolling interests as a component of total equity.
	When a Unit is redeemed (Note 1), the change in ownership is treated as an equity transaction by the General Partner and there is no effect on its earnings or net assets.
Revenue Recognition, Policy	'
	Revenue Recognition
	Rental and Related Revenue
	The timing of revenue recognition under an operating lease is determined based upon ownership of the tenant improvements. If we are the owner of the tenant improvements, revenue recognition commences after the improvements are completed and the tenant takes possession or control of the space. If we determine that the tenant allowances or improvements we are funding are lease incentives, then we commence revenue recognition when possession or control of the space is turned over to the tenant. Rental income from leases is recognized on a straight-line basis.
	We record lease termination fees when a tenant has executed a definitive termination agreement with us and the payment of the termination fee is not subject to any material conditions that must be met or waived before the fee is due to us.
	General Contractor and Service Fee Revenue
	Management fees are based on a percentage of rental receipts of properties managed and are recognized as the rental receipts are collected. Maintenance fees are based upon established hourly rates and are recognized as the services are performed. Construction management and development fees represent fee-based third-party contracts and are recognized as earned based on the percentage of completion method.
	We recognize income on construction contracts where we serve as a general contractor on the percentage of completion method. Using this method, profits are recorded based on our estimates of the percentage of completion of individual contracts, commencing when the work performed under the contracts reaches a point where the final costs can be estimated with reasonable accuracy. The percentage of completion estimates are based on a comparison of the contract expenditures incurred to the estimated final costs. Changes in job performance, job conditions and estimated profitability may result in revisions to costs and income and are recognized in the period in which the revisions are determined. To the extent that a fixed-price contract is estimated to result in a loss, the loss is recorded immediately.
	Unbilled and overbilled receivables on construction contracts totaled $9.9 million and $7.8 million, respectively, at December 31, 2013 and $18.4 million and $2.4 million, respectively, at December 31, 2012. Overbilled receivables are included in other liabilities in the Consolidated Balance Sheets.
Discontinued Operations, Policy	'
	Property Sales
	Gains on sales of all properties are recognized in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 360-20. The specific timing of the sale of a building is measured against various criteria in FASB ASC 360-20 related to the terms of the transactions and any continuing involvement in the form of management or financial assistance from the seller associated with the properties. We make judgments based on the specific terms of each transaction as to the amount of the total profit from the transaction that we recognize considering factors such as continuing ownership interest we may have with the buyer ("partial sales") and our level of future involvement with the property or the buyer that acquires the assets. If the full accrual sales criteria are not met, we defer gain recognition and account for the continued operations of the property by applying the finance, installment or cost recovery methods, as appropriate, until the full accrual sales criteria are met. Estimated future costs to be incurred after completion of each sale are included in the determination of the gain on sales.
	To the extent that a property has had operations prior to sale, and that we do not have continuing involvement with the property, gains from sales of depreciated property are included in discontinued operations and the proceeds from the sale of these held-for-rental properties are classified in the investing activities section of the Consolidated Statements of Cash Flows.
	Rental properties that do not meet the criteria for presentation as discontinued operations are classified as gain on sale of properties in the Consolidated Statements of Operations and Comprehensive Income.
Earnings Per Share, Policy	'
	Net Income (Loss) Per Common Share or Common Unit
	Basic net income (loss) per common share or Common Unit is computed by dividing net income (loss) attributable to common shareholders or common unitholders, less dividends or distributions on share-based awards expected to vest (referred to as "participating securities" and primarily composed of unvested restricted stock units), by the weighted average number of common shares or Common Units outstanding for the period.
	Diluted net income (loss) per common share is computed by dividing the sum of basic net income (loss) attributable to common shareholders and the noncontrolling interest in earnings allocable to Limited Partner Units (to the extent the Limited Partner Units are dilutive) by the sum of the weighted average number of common shares outstanding and, to the extent they are dilutive, Units outstanding and any potential dilutive securities for the period. Diluted net income (loss) per Common Unit is computed by dividing the basic net income (loss) attributable to common unitholders by the sum of the weighted average number of Common Units outstanding and any potential dilutive securities for the period.
	The following table reconciles the components of basic and diluted net income (loss) per common share or Common Unit (in thousands):

	Outstanding participating securities	3,871				4,099				4,780
Comprehensive Income, Policy	'
	Other Comprehensive Income
	In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-02, Other Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income ("ASU 2013-02"), which was effective for us beginning with the three months ended March 31, 2013. ASU 2013-02 requires presentation of significant amounts reclassified out of accumulated other comprehensive income. Activity within other comprehensive income or loss includes the amortization to interest expense, over the lives of previously hedged loans, of the values of interest rate swaps that have been settled, as well as changes in the fair values of currently outstanding interest rate swaps that we have designated as cash flow hedges. Activity within other comprehensive income is not material for any individual type of activity, as well as for all activities in the aggregate, for all periods presented in this Report.
Income Tax, Policy	'
	Federal Income Taxes
	General Partner
	The General Partner has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended. To qualify as a REIT, the General Partner must meet a number of organizational and operational requirements, including a requirement to distribute at least 90% of its REIT taxable income to its shareholders. Management intends to continue to adhere to these requirements and to maintain the General Partner's REIT status. As a REIT, the General Partner is entitled to a tax deduction for the dividends it pays to shareholders. Accordingly, the General Partner generally will not be subject to federal income taxes as long as it currently distributes to shareholders an amount equal to or in excess of its taxable income. The General Partner is also generally subject to federal income taxes on any taxable income that is not currently distributed to its shareholders. If the General Partner fails to qualify as a REIT in any taxable year, it will be subject to federal income taxes and may not be able to qualify as a REIT for four subsequent taxable years.
	REIT qualification reduces, but does not eliminate, the amount of state and local taxes we pay. In addition, our financial statements include the operations of taxable corporate subsidiaries that are not entitled to a dividends paid deduction and are subject to federal, state and local income taxes. As a REIT, the General Partner may also be subject to certain federal excise taxes if it engages in certain types of transactions.
	The following table reconciles the General Partner's net income (loss) to taxable income (loss) before the dividends paid deduction, and subject to the 90% distribution requirement, for the years ended December 31, 2013, 2012 and 2011 (in thousands):

		100	%		100	%		100	%
	Partnership
	For the Partnership, the allocated share of income and loss other than the operations of its taxable REIT subsidiary is included in the income tax returns of its partners; accordingly the only federal income taxes included in the accompanying consolidated financial statements of the Partnership are in connection with its taxable REIT subsidiary.
	Deferred Tax Assets
	A full valuation allowance for the deferred tax assets of the taxable REIT subsidiary was maintained for 2013, 2012 and 2011.  Based on the level of historical taxable income and projections of taxable income under our current operating strategy, management believes that it is more likely than not that the taxable REIT subsidiary will not generate sufficient taxable income to realize any of its deferred tax assets.  Income taxes are not material to our operating results or financial position. Our taxable REIT subsidiary has no significant net deferred income tax positions or unrecognized tax benefit items.
	Cash Paid for Income Taxes
	We paid state and local income taxes of $830,000, $580,000 and $340,000 in 2013, 2012 and 2011, respectively.
Fair Value Measurements Policy	'
	Fair Value Measurements
	We follow the framework established under accounting standard FASB ASC 820 for measuring fair value of non-financial assets and liabilities that are not required or permitted to be measured at fair value on a recurring basis but only in certain circumstances, such as a business combination.
	Assets and liabilities recorded at fair value on the consolidated balance sheets are categorized based on the inputs to the valuation techniques as follows:
	Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities to which we have access.
	Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates and yield curves that are observable at commonly quoted intervals.
	Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity's own assumptions, as there is little, if any, related market activity.
	In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.
Use of Estimates, Policy	'
	Use of Estimates
	The preparation of the financial statements requires management to make a number of estimates and assumptions that affect the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. The most significant estimates, as discussed within our Summary of Significant Accounting Policies, pertain to the critical assumptions utilized in testing real estate assets for impairment, estimating the fair value of real estate assets when an impairment event has taken place and allocating the purchase price of acquired properties to tangible and intangible assets based on their respective fair values. Actual results could differ from those estimates.
