EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended June 30, 2015 of both Duke Realty Corporation and Duke Realty Limited Partnership. Unless stated otherwise or the context otherwise requires, references to "Duke Realty Corporation" or the "General Partner" mean Duke Realty Corporation and its consolidated subsidiaries; and references to the "Partnership" mean Duke Realty Limited Partnership and its consolidated subsidiaries. The terms the "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.

Duke Realty Corporation is a self-administered and self-managed real estate investment trust ("REIT") and is the sole general partner of the Partnership, owning 99.0% of the common partnership interests of the Partnership ("General Partner Units") as of June 30, 2015. The remaining 1.0% 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 also owns all of the issued and outstanding preferred partnership interests in the Partnership ("Preferred Units"), to the extent the Partnership has issued Preferred Units.

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.

We believe combining the quarterly reports on Form 10-Q of the General Partner and the Partnership into this single report results in the following benefits:

• enhances investors' understanding of the General Partner and the Partnership by enabling investors to view the business as a whole in the same manner as management views and operates the business;

• eliminates duplicative disclosure and provides a more streamlined and readable presentation of information since a substantial portion of the Company's disclosure applies to both the General Partner and the Partnership; and

• creates time and cost efficiencies through the preparation of one combined report instead of two separate reports.

We believe it is important to understand the few differences between the General Partner and the Partnership in the context of how we operate as an interrelated consolidated company. The General Partner's only material asset is its ownership of partnership interests in the Partnership. As a result, the General Partner does not conduct business itself, other than acting as the sole general partner of the Partnership and issuing public equity from time to time. The General Partner does not issue any indebtedness, but does guarantee some of the unsecured debt of the Partnership. The Partnership holds substantially all the assets of the business, directly or indirectly, and holds the ownership interests related to certain of the Company's investments. The Partnership conducts the operations of the business and has no publicly traded equity. Except for net proceeds from equity issuances by the General Partner, which are contributed to the Partnership in exchange for General Partner Units or Preferred Units, the Partnership generates the capital required by the business through its operations, its incurrence of indebtedness and the issuance of Limited Partner Units to third parties.

Noncontrolling interests, shareholders' equity and partners' capital are the main areas of difference between the consolidated financial statements of the General Partner and those of the Partnership. The noncontrolling interests in the Partnership's financial statements include the interests in consolidated investees not wholly owned by the Partnership. The noncontrolling interests in the General Partner's financial statements include the same noncontrolling interests at the Partnership level, as well as the common limited partnership interests in the Partnership, which are accounted for as partners' capital by the Partnership.

In order to highlight the differences between the General Partner and the Partnership, there are separate sections in this report, as applicable, that separately discuss the General Partner and the Partnership, including separate financial statements and separate Exhibit 31 and 32 certifications. In the sections that combine disclosure of the General Partner and the Partnership, this report refers to actions or holdings as being actions or holdings of the collective Company.

DUKE REALTY CORPORATION AND DUKE REALTY LIMITED PARTNERSHIP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.    General Basis of Presentation

The interim consolidated financial statements included herein have been prepared by Duke Realty Corporation (the "General Partner") and Duke Realty Limited Partnership (the "Partnership"). In this Report, unless the context indicates otherwise, 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 2014 year-end consolidated balance sheet data included in this Quarterly Report on Form 10-Q (this "Report") was derived from the audited financial statements in the combined Annual Report on Form 10-K of the General Partner and the Partnership for the year ended December 31, 2014, but does not include all disclosures required by accounting principles generally accepted in the United States of America ("GAAP"). The financial statements have been prepared in accordance with GAAP for interim financial information and in accordance with Rule 10-01 of Regulation S-X of the Securities Exchange Act of 1934, as amended. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenue and expenses during the reporting period. Our actual results could differ from those estimates and assumptions. These financial statements should be read in conjunction with Management's Discussion and Analysis of Financial Condition and Results of Operations included herein and the consolidated financial statements and notes thereto included in the combined Annual Report on Form 10-K of the General Partner and the Partnership for the year ended December 31, 2014.

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"). 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. Simultaneously, the Partnership completed the acquisition of Duke Associates, a full-service commercial real estate firm operating in the Midwest whose operations began in 1972.

The General Partner is the sole general partner of the Partnership, owning approximately 99.0% of the common partnership interests of the Partnership ("General Partner Units") at June 30, 2015. The remaining 1.0% 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 Fifth 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"), to the extent the Partnership has issued Preferred Units.

11

As of June 30, 2015, we owned and operated a portfolio primarily consisting of industrial, medical office and office properties and provide real estate services to third-party owners. Substantially all of our Rental Operations (see Note 10) are conducted through the Partnership. We conduct our Service Operations (see Note 10) 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. The consolidated financial statements include our accounts and the accounts of our majority-owned or controlled subsidiaries.

2.    New Accounting Pronouncements

Revenue Recognition

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). ASU 2014-09 is a comprehensive revenue recognition standard that will supersede nearly all existing GAAP revenue recognition guidance as well as impact the existing GAAP guidance governing the sale of nonfinancial assets. The standard’s core principle is that a company will recognize revenue when it satisfies performance obligations, by transferring promised goods or services to customers, in an amount that reflects the consideration to which the company expects to be entitled in exchange for fulfilling those performance obligations. In doing so, companies will need to exercise more judgment and make more estimates than under existing GAAP guidance.

ASU 2014-09 will be effective for public entities for annual and interim reporting periods beginning after December 15, 2017 and early adoption is permitted in periods ending after December 15, 2016. The changes to the effective date and early adoption are still subject to final approval. ASU 2014-09 allows for either recognizing the cumulative effect of application (i) at the start of the earliest comparative period presented (with the option to use any or all of three practical expedients) or (ii) at the date of initial application, with no restatement of comparative periods presented.

We have not yet selected a transition method nor have we determined the effect of ASU 2014-09 on our consolidated financial statements.

Consolidation

In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis ("ASU 2015-02"). ASU 2015-02 makes targeted amendments to the current consolidation guidance and ends the deferral granted to investment companies from applying the existing variable interest entity guidance. ASU 2015-02 will be effective for public entities for annual and interim reporting periods beginning after December 15, 2015 with early adoption allowed in any interim period. We have not yet selected a transition method and are currently assessing the effect of ASU 2015-02 on our consolidated financial statements.

Debt Issuance Costs

In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"). ASU 2015-03 will require that debt issuance costs related to a recognized debt liability, which are currently presented as deferred charges (assets), be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. ASU 2015-03 will be effective for financial statements issued for fiscal years beginning after December 15, 2015, and for interim periods within those fiscal years. We do not expect ASU 2015-03 to have a material effect on our consolidated financial statements.

3.    Reclassifications

Certain amounts in the accompanying consolidated financial statements for 2014 have been reclassified to conform to the 2015 consolidated financial statement presentation.

12

4.    Variable Interest Entities

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 variable interest entities ("VIE"s) 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 own interests in a VIE and 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 and would consolidate the VIE. To the extent we own interest in a VIE, then at each reporting period, we re-assess our conclusions as to which, if any, party within the VIE is considered the primary beneficiary.

There were no consolidated or unconsolidated joint ventures at June 30, 2015 that met the criteria to be considered VIEs. Our maximum loss exposure for guarantees of joint venture indebtedness, for joint ventures that are not VIEs, totaled $76.3 million at June 30, 2015.

5.    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.

Acquisitions

We acquired one industrial property during the six months ended June 30, 2015. The following table summarizes the fair value of amounts recognized for each major class of asset and liability (in thousands) for this acquisition:

Real estate assets	$	18,246
Lease related intangible assets	2,001
Total acquired assets	20,247
Other liabilities	206
Total assumed liabilities	206
Fair value of acquired net assets	$	20,041

The leases in the acquired property had an average remaining life at acquisition of approximately 9.2 years.

We have included $77,000 in rental revenues and $57,000 in income from continuing operations during the six months ended June 30, 2015 for the property since its date of acquisition.

Fair Value Measurements

The fair value estimates used in allocating the aggregate purchase price of an acquisition among the individual components of real estate assets and liabilities were determined primarily through calculating the "as-if vacant" value of a building, using the income approach, and relied significantly upon internally determined assumptions. We have determined that these estimates primarily rely 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 for acquisition activity during the six months ended June 30, 2015 are as follows:

13

Discount rate	7.07%
Exit capitalization rate	5.57%
Lease-up period (months)	12
Net rental rate per square foot - Industrial	$4.85

Acquisition-Related Activity

The acquisition-related activity in our consolidated Statements of Operations and Comprehensive Income consisted of transaction costs for completed acquisitions and adjustments to the fair value of contingent consideration from acquisitions after the measurement period is complete.

Dispositions

Dispositions of buildings (see Note 11 for the number of buildings sold as well as for their classification between continuing and discontinued operations) and undeveloped land generated net cash proceeds of $1.31 billion and $213.0 million during the six months endedJune 30, 2015 and 2014, respectively.

On April 1, 2015, we completed the previously announced suburban office portfolio sale (the "Suburban Office Portfolio Sale") to a joint venture with affiliates of Starwood Capital Group, Vanderbilt Partners and Trinity Capital Advisors for approximately $1.07 billion in proceeds and recorded a gain on sale of $398.6 million. The Suburban Office Portfolio Sale includes all of our wholly-owned, in-service suburban office properties located in Nashville, Raleigh, South Florida and St. Louis. The portfolio included approximately 6.7 million square feet across 61 buildings and 57 acres of undeveloped land. One additional office asset currently under construction in Raleigh is expected to be sold upon completion in late 2015.

A portion of the purchase price for the Suburban Office Portfolio Sale was financed through a $200.0 million first mortgage on certain of the properties in the Suburban Office Portfolio that we provided to the seller. The first mortgage matures on December 31, 2016, is prepayable after January 1, 2016, and bears interest at LIBOR plus 1.5%. We have reviewed the creditworthiness of the entities with which we hold this first mortgage and have concluded it is probable that we will be able to collect all amounts due according to its contractual terms.

On April 8, 2015, we completed the sale of 51 non-strategic industrial properties for $270.0 million in proceeds and recorded a gain on sale of $106.6 million. These properties totaled 5.2 million square feet and were located in primarily Midwest markets.

6.    Indebtedness

All debt is held directly or indirectly by the Partnership. The General Partner does not have any indebtedness, but does guarantee some of the unsecured debt of the Partnership. The following table summarizes the book value and changes in the fair value, of our debt for the six months endedJune 30, 2015 (in thousands):

	Book Value at 12/31/2014		Book Value at 6/30/2015		Fair Value at 12/31/2014		Payments/Payoffs			Adjustments to Fair Value			Fair Value at 6/30/2015
Fixed rate secured debt	$	979,842	$	775,469	$	1,065,301	$	(202,918	)	$	(16,404	)	$	845,979
Variable rate secured debt	3,400		3,400		3,400		—			—			3,400
Unsecured debt	3,364,161		2,681,874		3,603,475		(682,287		)	(111,749		)	2,809,439
Unsecured line of credit	106,000		—		106,000		(106,000		)	—			—
Total	$	4,453,403	$	3,460,743	$	4,778,176	$	(991,205	)	$	(128,153	)	$	3,658,818
Less secured debt related to real estate assets held-for-sale	40,764		—
Total indebtedness as reported on consolidated balance sheets	$	4,412,639	$	3,460,743

Secured Debt

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 2.20% to 3.70%, 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.

During the six months endedJune 30, 2015, we repaid fifteen secured loans, totaling $197.6 million. These loans had a weighted average stated interest rate of 5.32%. Certain of these secured loans were repaid prior to their scheduled maturity date, which resulted in a $3.8 million loss on extinguishment, which included both prepayment penalties as well as the write-off of unamortized deferred loan and mark to market costs.

Unsecured Debt

At June 30, 2015, with the exception of one variable rate term note, 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. The estimated trading values of our fixed rate unsecured debt, depending on the maturity and coupon rates, ranged from 98.00% to 126.00% of face value.

We utilize a discounted cash flow methodology in order to estimate the fair value of our $250.0 million 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. Our estimate of the current market rate for our variable rate term loan was 1.34% and was based primarily upon Level 3 inputs.

In February 2015, we repaid a $250.0 million senior unsecured note at its maturity date. This loan had a stated interest rate of 7.38% and an effective rate of 7.50%.

In April 2015, the Partnership completed a tender offer (the "Tender Offer") to purchase, for a combined aggregate purchase price (exclusive of accrued and unpaid interest) of up to $500.0 million, certain of its outstanding series of unsecured notes. A portion of the proceeds from the Suburban Office Portfolio Sale were used to fund the Tender Offer, which resulted in the repurchase of notes having a face value of $424.9 million, for a cash payment of $500.0 million. The repurchased notes had contractual maturity dates ranging between February 2017 and March 2020 and bore interest at stated rates ranging between 5.95% and 8.25%. Additionally, in May 2015, we repurchased unsecured notes with a face value of $6.3 million, for a cash payment of $7.1 million. These notes had a stated interest rate of 6.50% and an effective rate of 6.08%. The early repayment of unsecured notes, either through the Tender Offer or repurchase, resulted in an aggregate loss on extinguishment of $78.9 million, which included applicable repurchase premiums as well as the write-off of unamortized deferred loan costs.

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 June 30, 2015.

Unsecured Line of Credit

Our unsecured line of credit at June 30, 2015 is described as follows (in thousands):

Description	Maximum Capacity		Maturity Date	Outstanding Balance at June 30, 2015
Unsecured Line of Credit - Partnership	$	1,200,000	January 2019	$	—

The Partnership's unsecured line of credit has an interest rate on borrowings of LIBOR plus 1.05% and a maturity date of January 2019. 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 $1.6 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 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 June 30, 2015, we were in compliance with all covenants under this line of credit.

7.    Shareholders' Equity of the General Partner and Partners' Capital of the Partnership

General Partner

During the six months endedJune 30, 2015, the General Partner issued 233,000 common shares pursuant to its at the market equity program, generating gross proceeds of approximately $5.0 million and, after deducting commissions and other costs, net proceeds of approximately $4.8 million. The proceeds from these offerings were contributed to the Partnership and used for general corporate purposes.

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.

8.    Related Party Transactions

We provide property management, asset management, leasing, construction and other tenant-related services to unconsolidated companies in which we have equity interests. We recorded the corresponding fees based on contractual terms that approximate market rates for these types of services and have eliminated our ownership percentage of these fees in the consolidated financial statements. The following table summarizes the fees earned from these companies, prior to the elimination of our ownership percentage, for the six months endedJune 30, 2015 and 2014, respectively (in thousands): 

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2015		2014		2015		2014
Management fees	$	1,752	$	2,117	$	3,553	$	4,336
Leasing fees	389		2,169		1,022		2,513
Construction and development fees	725		2,417		1,130		3,382

9.    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 per common share or Common Unit for the three and six months endedJune 30, 2015 and 2014, respectively (in thousands):

10.    Segment Reporting

Reportable Segments

We had four reportable operating segments at June 30, 2015, the first three of which consist of the ownership and rental of (i) industrial, (ii) medical office and (iii) office real estate investments. The operations of our industrial, medical office and office properties, along with our retail properties, are collectively referred to as "Rental Operations." Properties not included in our reportable segments, which do not by themselves meet the quantitative thresholds for separate presentation as a reportable segment, are referred to as non-reportable Rental Operations. 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.

Revenues by Reportable Segment

The following table shows the revenues for each of the reportable segments, as well as a reconciliation to consolidated revenues, for the three and six months endedJune 30, 2015 and 2014, respectively (in thousands): 

	Three Months Ended June 30,				Six Months Ended June 30,

Consolidated revenue	$	225,946	$	303,623	$	525,497	$	598,161

Supplemental Performance Measure

Property level net operating income on a cash basis ("PNOI") is the non-GAAP supplemental performance measure that we use to evaluate the performance of, and to allocate resources among, the real estate investments in the reportable and operating segments that comprise our Rental Operations. PNOI for our Rental Operations segments is comprised of rental revenues from continuing operations less rental expenses and real estate taxes from continuing operations, along with certain other adjusting items (collectively referred to as "Rental Operations revenues and expenses excluded from PNOI," as shown in the following table). Additionally, we do not allocate interest expense, depreciation expense and certain other non-property specific revenues and expenses (collectively referred to as "Non-Segment Items," as shown in the following table) to our individual operating segments.

We evaluate the performance of our Service Operations reportable segment using net income or loss, as allocated to that segment ("Earnings from Service Operations").

The following table shows a reconciliation of our segment-level measures of profitability to consolidated income from continuing operations before income taxes for the three and six months endedJune 30, 2015 and 2014, respectively (in thousands and excluding discontinued operations):

Income from continuing operations before income taxes	$	55,707		$	129,115		$	94,626		$	136,663

The most comparable GAAP measure to PNOI is income from continuing operations before income taxes. PNOI excludes expenses that materially impact our overall results of operations and, therefore, should not be considered as a substitute for income from continuing operations before income taxes or any other measures derived in accordance with GAAP. Furthermore, PNOI may not be comparable to other similarly titled measures of other companies.

11.    Discontinued Operations and Assets Held-for-Sale

Discontinued Operations

Beginning with our adoption of ASU 2014-08 on April 1, 2014, discontinued operations presentation applies only to disposals representing a strategic shift that has (or will have) a major effect on an entity’s operations and financial results (e.g., a disposal of a major geographical area, a major line of business, a major equity method investment or other major parts of an entity).

On April 1, 2015, we completed the Suburban Office Portfolio Sale that had been under agreement for sale since late January 2015. Because of the size of this disposition, and the fact that it represented our exit from the office product type in four geographic markets, we determined that the disposition represented a strategic shift that would have a major effect on our operations and financial results. As such, the in-service properties in this portfolio met the criteria to be classified within discontinued operations. As the result of its classification within discontinued operations, the in-service assets and liabilities of this portfolio are required to be presented as held-for-sale for all prior periods presented in our Consolidated Balance Sheets.

The following table illustrates the number of sold or held-for-sale properties included in, or excluded from, discontinued operations:

	Held-for-Sale at June 30, 2015	Sold through June 30, 2015	Sold in 2014	Total
Industrial	0	5	11	16
Medical Office	0	1	1	2
Office	0	56	0	56
Total properties included in discontinued operations	0	62	12	74
Properties excluded from discontinued operations	9	62	17	88
Total properties sold or classified as held-for-sale	9	124	29	162

For the properties that were classified in discontinued operations, we allocated 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

20

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.

The following table illustrates the operational results of the buildings reflected in discontinued operations for the six months endedJune 30, 2015 and 2014, respectively (in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,

Income from discontinued operations	$	396,170		$	7,776		$	424,704		$	28,473

Capital expenditures on a cash basis for the six months endedJune 30, 2015 and 2014 were $7.4 million and $9.9 million, respectively, related to properties classified within discontinued operations.

Cautionary Notice Regarding Forward-Looking Statements

Certain statements contained in or incorporated by reference into this Report, including, without limitation, those related to our future operations, constitute "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. The words "believe," "estimate," "expect," "anticipate," "intend," "plan," "seek," "may," "could" and similar expressions or statements regarding future periods are intended to identify forward-looking statements, although not all forward-looking statements contain such words.

These forward-looking statements involve known and unknown risks, uncertainties and other important factors that could cause our actual results, performance or achievements, or industry results, to differ materially from any predictions of future results, performance or achievements that we express or imply in this Report. Some of the risks, uncertainties and other important factors that may affect future results include, among others:

• Changes in general economic and business conditions, including the financial condition of our tenants and the value of our real estate assets;

• The General Partner's continued qualification as a real estate investment trust ("REIT") for U.S. federal income tax purposes;

• Heightened competition for tenants and potential decreases in property occupancy;

• Potential changes in the financial markets and interest rates;

• Volatility in the General Partner's stock price and trading volume;

• Our continuing ability to raise funds on favorable terms;

• Our ability to successfully identify, acquire, develop and/or manage properties on terms that are favorable to us;

• Potential increases in real estate construction costs;

• Our ability to successfully dispose of properties on terms that are favorable to us, including, without limitation, through one or more transactions that are consistent with our previously disclosed strategic plans;

• Other risks and uncertainties described herein, as well as those risks and uncertainties discussed from time to time in our other reports and other public filings with the SEC.

Although we presently believe that the plans, expectations and results expressed in or suggested by the forward-looking statements are reasonable, all forward-looking statements are inherently subjective, uncertain and subject to change, as they involve substantial risks and uncertainties, including those beyond our control. New factors emerge from time to time, and it is not possible for us to predict the nature, or assess the potential impact, of each new factor on our business. Given these uncertainties, we caution you not to place undue reliance on these forward-looking statements. We undertake no obligation to update or revise any of our forward-looking statements for events or circumstances that arise after the statement is made, except as otherwise may be required by law.

The above list of risks and uncertainties is only a summary of some of the most important factors and is not intended to be exhaustive. Additional information regarding risk factors that may affect us is included in our combined Annual Report on Form 10-K for the fiscal year ended December 31, 2014, which we filed with the SEC on February 20, 2015. The risk factors contained in our Annual Report are updated by us from time to time in Quarterly Reports on Form 10-Q and other public filings. 

Business Overview

The General Partner is a self-administered and self-managed REIT that began operations in 1986 and is the sole general partner of the Partnership. The Partnership is a limited partnership formed in 1993, at which time all of the properties and related assets and liabilities of the General Partner, as well as proceeds from a secondary offering of the General Partner's common shares, were contributed to the Partnership. Simultaneously, the Partnership completed the acquisition of Duke Associates, a full-service commercial real estate firm operating in the Midwest whose operations began in 1972. We operate the General Partner and the Partnership as one enterprise, and therefore, our discussion and analysis refers to the General Partner and its consolidated subsidiaries, including the Partnership, collectively. A more complete description of our business, and of management's philosophy and priorities, is included in our 2014 Annual Report on Form 10-K.

At June 30, 2015, we:

• Owned or jointly controlled 611 industrial, medical office and office properties, of which 583 properties with approximately137.1 million square feet were in service and 28 properties with approximately6.7 million square feet were under development. The 583 in-service properties were comprised of 505 consolidated properties with approximately117.2 million square feet and 78 jointly controlled unconsolidated properties with approximately19.9 million square feet. The 28 properties under development consisted of 25 consolidated properties with more than5.6 million square feet and three jointly controlled unconsolidated properties with more than1.0 million square feet.

• Owned directly, or through ownership interests in unconsolidated joint ventures (with acreage not adjusted for our percentage ownership interest), approximately 3,600 acres of land and controlled approximately 1,700 acres through purchase options.

A key component of our overall strategy is to increase our investment in quality industrial and medical office properties in both existing and select new markets and to reduce our investment in suburban office properties and other non-strategic assets.

We had four reportable operating segments at June 30, 2015, the first three of which consist of the ownership and rental of (i) industrial, (ii) medical office and (iii) office real estate investments. The operations of our industrial, medical office and office properties, along with our retail properties, are collectively referred to as "Rental Operations." The fourth reportable segment consists of various real estate services such as property management, asset management, maintenance, leasing, development, general contractor 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. Our Service Operations segment also includes our taxable REIT subsidiary, a legal entity through which certain of the segment's operations are conducted.

Key Performance Indicators

Our operating results depend primarily upon rental income from our Rental Operations. The following discussion highlights the areas of Rental Operations that we consider critical drivers of future revenues.

Occupancy Analysis

Our ability to maintain high occupancy rates is a principal driver of maintaining and increasing rental revenue. The following table sets forth percent leased and average net effective rent information regarding our in-service portfolio

24

of rental properties, including properties classified within both continuing and discontinued operations, at June 30, 2015 and 2014, respectively:

* Represents the percentage change in net effective rent between the original leases and the renewal leases. Net effective rents represent average annual base rental payments, on a straight-line basis for the term of each lease, excluding operating expense reimbursements.

Lease Expirations

Our ability to maintain and improve occupancy rates and net effective rents primarily depends upon our continuing ability to re-lease expiring space. The table below reflects our consolidated in-service portfolio lease expiration schedule, excluding the leases in properties designated as held-for-sale, at June 30, 2015 (in thousands, except percentage data and number of leases):

* Annualized rental revenue represents average annual base rental payments, on a straight-line basis for the term of each lease, from space leased to tenants at the end of the most recent reporting period. Annualized rental revenue excludes additional amounts paid by tenants as reimbursement for operating expenses.

Information on current market rents can be difficult to obtain, is highly subjective, and is often not directly comparable between properties. As a result, we believe the increase or decrease in net effective rent on lease renewals, as previously defined, is the most objective and meaningful relationship between rents on leases expiring in the near-term and current market rents.

Building Acquisitions

Our decision process in determining whether or not to acquire a target property or portfolio of properties involves several factors, including expected rent growth, multiple yield metrics, property locations and expected demographic growth in each location, current occupancy of the target properties, tenant profile and remaining terms of the in-place leases in the target properties. We pursue both brokered and non-brokered acquisitions, and it is difficult to predict which markets and product types may present acquisition opportunities that align with our strategy. Because of the numerous factors considered in our acquisition decisions, we do not establish specific target yields for future acquisitions.

We acquired one building during the six months endedJune 30, 2015 and five buildings during the year ended December 31, 2014. The following table summarizes the acquisition price, percent leased at time of acquisition and in-place yields, by product type, for these acquisitions (in thousands, except percentage data):

28

	Year-to-Date 2015 Acquisitions						Full Year 2014 Acquisitions

* Includes real estate assets and net acquired lease-related intangible assets, including above or below market leases, but excludes other acquired working capital assets and liabilities.
** In-place yields of completed acquisitions are calculated as the current annualized net rental payments from space leased to tenants at the date of acquisition, divided by the acquisition price of the acquired real estate. Annualized net rental payments are comprised of base rental payments, excluding additional amounts payable by tenants as reimbursement for operating expenses, less current annualized operating expenses not recovered through tenant reimbursements.
*** Represents percentage of total square feet leased based on executed leases and without regard to whether the leases have commenced, at the date of acquisition.

Building Dispositions

We regularly work to identify, consider and pursue opportunities to dispose of properties on an opportunistic basis and on a basis that is generally consistent with our strategic plans.

We sold124 buildings during the six months ended June 30, 2015 and 29 buildings during the year ended December 31, 2014. The following table summarizes the sales prices, in-place yields and percent leased, by product type, of these buildings (in thousands, except percentage data):

	Year-to-Date 2015 Dispositions						Full Year 2014 Dispositions

*   In-place yields of completed dispositions are calculated as current annualized net rental payments from space leased to tenants at the date of sale, divided by the sales price of the real estate. Annualized net rental payments are comprised of base rental payments, excluding additional amounts payable by tenants as reimbursement for operating expenses, less current annualized operating expenses not recovered through tenant reimbursements.
** Represents percentage of total square feet leased based on executed leases where the leases have commenced.

On April 1, 2015, we completed the previously announced suburban office portfolio sale (the "Suburban Office Portfolio Sale", see Note 5 to the Consolidated Financial Statements), which included 61 buildings consisting of all of our wholly-owned, in-service suburban office properties located in Nashville, Raleigh, South Florida and St. Louis. One additional office asset currently under construction in Raleigh is expected to be sold upon completion in late 2015.

On April 8, 2015, we completed the sale of a portfolio of 51 non-strategic light industrial properties, located in primarily Midwest markets.

Development

At June 30, 2015, we had 6.7 million square feet of property under development with total estimated costs upon completion of $604.1 million compared to 10.8 million square feet with total estimated costs upon completion of $784.3 million at June 30, 2014. The square footage and estimated costs include both consolidated properties and unconsolidated joint venture development activity at 100%.

29

The following table summarizes our properties under development at June 30, 2015 (in thousands, except percentage data): 

Ownership Type	Square Feet	Percent Leased	Total Estimated Project Costs		Total Incurred to Date		Amount Remaining to be Spent
Consolidated properties	5,637	40%	$	554,470	$	210,814	$	343,656
Unconsolidated joint venture properties	1,026	78%	49,622		8,261		41,361
Total	6,663	46%	$	604,092	$	219,075	$	385,017

The development pipeline under construction, for consolidated properties, at June 30, 2015 includes one, 137,000 square foot, suburban office property that is under contract to sell upon completion to the same buyer as the Suburban Office Portfolio Sale.

Supplemental Performance Measures

In addition to net income (loss) computed in accordance with GAAP, we assess and measure the overall operating results of the General Partner and the Partnership using certain non-GAAP supplemental performance measures, which include (i) Funds From Operations ("FFO"), (ii) Property Level Net Operating Income - Cash Basis ("PNOI") and (iii) Same Property Net Operating Income - Cash Basis ("SPNOI").

These non-GAAP metrics are commonly used by industry analysts and investors as supplemental operating performance measures of REITs and are viewed by management to be useful indicators of operating performance. 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, PNOI and SPNOI, 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.

The most comparable GAAP measure to FFO is net income (loss) attributable to common shareholders or common unitholders, while the most comparable GAAP measure to PNOI and SPNOI is income from continuing operations before income taxes.

FFO, PNOI and SPNOI each exclude expenses that materially impact our overall results of operations and, therefore, should not be considered as a substitute for net income (loss) attributable to common shareholders or common unitholders, income from continuing operations before income taxes, or any other measures derived in accordance with GAAP. Furthermore, these metrics may not be comparable to other similarly titled measures of other companies.

Funds From Operations

The National Association of Real Estate Investment Trusts ("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. We calculate FFO in accordance with the definition that was adopted by the Board of Governors of NAREIT.

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 assists them in comparing these operating results between periods or between different companies that use the NAREIT definition of FFO.

The following table shows a reconciliation of net income attributable to common shareholders or common

unitholders to the calculation of FFO attributable to common shareholders or common unitholders for the three and six months endedJune 30, 2015 and 2014, respectively (in thousands):

Property Level Net Operating Income - Cash Basis

PNOI is comprised of rental revenues from continuing operations less rental expenses and real estate taxes from continuing operations, along with certain other adjusting items that are detailed in the table below. As a performance metric that consists of only the cash-based revenues and expenses directly related to ongoing real estate rental operations, PNOI is narrower in scope than FFO.

PNOI, as we calculate it, may not be directly comparable to similarly titled, but differently calculated, measures for other REITs. We believe that PNOI is another useful supplemental performance measure, as it is an input in many REIT valuation models and it provides a means by which to evaluate the performance of the properties within our Rental Operations segments.

The major factors influencing PNOI are occupancy levels, acquisitions and sales, development properties that achieve stabilized operations, rental rate increases or decreases, and the recoverability of operating expenses. PNOI was calculated as follows for the three and six months endedJune 30, 2015 and 2014 (in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,
	2015			2014			2015			2014

PNOI, Continuing Operations	$	140,864		$	141,129		$	283,136		$	274,180

31

A reconciliation of PNOI for our Rental Operations segments to income (loss) from continuing operations before income taxes is provided in Note 10 to the consolidated financial statements included in Part I, Item 1 of this Report. PNOI from continuing operations increased largely as the result of acquisitions and developments placed in service and improved occupancy, partially offset by the impact of property dispositions, as is described further in the Comparison of Six Months Ended June 30, 2015 to Six Months Ended June 30, 2014, below.

Same Property Net Operating Income - Cash Basis

We also evaluate the performance of our properties, including our share of properties we jointly control, on a "same property" basis, using a metric referred to as SPNOI. We view SPNOI as a useful supplemental performance measure because it improves comparability between periods by eliminating the effects of changes in the composition of our portfolio.

On an individual property basis, SPNOI is generally computed in a consistent manner as PNOI.

We have defined our same property portfolio, for the three months ended June 30, 2015, as those properties that have been owned and in operation throughout the twenty-four months ended June 30, 2015. In addition to excluding properties that have not been owned and in operation for the twenty-four months ended June 30, 2015, we have also excluded properties from our same property portfolio where revenues from individual lease buyouts in excess of $250,000 have been recognized. A reconciliation of SPNOI to PNOI and income or loss from continuing operations before income taxes is presented as follows (in thousands):

	Three Months Ended June 30,						Percent
	2015			2014			Change
SPNOI	$	121,145		$	114,101		6.2%
Less share of SPNOI from unconsolidated joint ventures	(7,748		)	(7,283		)
PNOI excluded from the same property population	24,716			18,005
Earnings from Service Operations	2,163			5,655
Rental Operations revenues and expenses excluded from PNOI	5,899			19,164
Non-Segment Items	(90,468		)	(20,527		)
Income from continuing operations before income taxes	$	55,707		$	129,115

The composition of the line items titled "Rental Operations revenues and expenses excluded from PNOI" and "Non-Segment Items" from the table above are shown in greater detail in Note 10 to the consolidated financial statements included in Part I, Item 1 of this Report.

We believe that the factors that impact SPNOI are generally the same as those that impact PNOI. The following table details the number of properties, square feet, average occupancy and cash rental rates for the properties included in SPNOI for the respective periods:

	Three Months Ended June 30,
	2015	2014
Number of properties	515	515
Square feet (in thousands) (1)	103,915	103,915
Average commencement occupancy percentage (2)	96.4%	94.4%
Average rental rate - cash basis (3)	$5.05	$5.00
(1) Includes the total square feet of the consolidated properties that are in the same property population as well as 5.6 million square feet of space for unconsolidated joint ventures, which represents our ratable share of the 16.8 million total square feet of space for buildings owned by unconsolidated joint ventures that are in the same property population.
(2) Commencement occupancy represents the percentage of total square feet where the leases have commenced.
(3) Represents the average annualized contractual rent per square foot for the three-month periods ended June 30, 2015 and 2014 for tenants in occupancy in properties in the same property population. Cash rent does not include the tenant's obligation to pay property operating expenses and real estate taxes. If a tenant was within a free rent period at June 30, 2015 or 2014 its rent would equal zero for purposes of this metric.

Comparison of Three Months Ended June 30, 2015 to Three Months Ended June 30, 2014

Rental and Related Revenue

The following table sets forth rental and related revenue from continuing operations by reportable segment for the three months ended June 30, 2015 and 2014, respectively (in thousands):

	Three Months Ended June 30,
	2015		2014
Rental and related revenue:
Industrial	$	135,487	$	128,263
Medical Office	40,274		34,954
Office	23,691		38,586
Other	2,544		2,977
Total rental and related revenue from continuing operations	$	201,996	$	204,780
Rental and Related Revenue from Discontinued Operations	49		29,331
Total Rental and Related Revenue from Continuing and Discontinued Operations	$	202,045	$	234,111

The following factors contributed to the decrease in rental and related revenue from continuing operations:

33

• The sale of 79 properties since January 1, 2014, which did not meet the criteria to be classified within discontinued operations resulted in a $22.2 million decrease in rental and related revenue from continuing operations in the three months ended June 30, 2015, as compared to the same period in 2014.

• We acquired six properties and placed 44 developments in service from January 1, 2014 to June 30, 2015, which provided incremental revenues of $11.5 million in the second quarter of 2015, as compared to the same period in 2014, which partially offset the overall decrease in rental and related revenue from continuing operations.

• Increased occupancy within our same property portfolio also partially offset the impact of dispositions on rental and related revenues from continuing operations. Average commencement occupancy in our same property portfolio increased by 2.0% from the three months ended June 30, 2014.

Rental Expenses and Real Estate Taxes

The following table sets forth rental expenses and real estate taxes from continuing operations by reportable segment for the three months ended June 30, 2015 and 2014, respectively (in thousands):

	Three Months Ended June 30,
	2015			2014
Rental expenses:
Industrial	$	12,458		$	12,270
Medical Office	8,068			7,163
Office	7,302			11,268
Other	2,266			1,520
Total rental expenses from continuing operations	$	30,094		$	32,221
Rental Expenses from Discontinued Operations	181			7,698
Total Rental Expenses from Continuing and Discontinued Operations	$	30,275		$	39,919
Real estate taxes:
Industrial	$	20,447		$	19,358
Medical Office	4,697			3,911
Office	2,468			4,858
Other	135			525
Total real estate tax expense from continuing operations	$	27,747		$	28,652
Real Estate Tax Expense from Discontinued Operations	(168		)	3,403
Total Real Estate Tax Expense from Continuing and Discontinued Operations	$	27,579		$	32,055

Rental expenses from continuing operations decreased by $2.1 million in three months ended June 30, 2015, compared to the same period in 2014. The decreased rental expenses were primarily the result of the sale of 79 properties since January 1, 2014, which did not meet the criteria to be classified within discontinued operations. The sale of these properties resulted in a $4.5 million decrease in rental expenses from continuing operations in the three months ended June 30, 2015, as compared to the same period in 2014. Partially offsetting this decrease was an increase in incremental rental expenses of $1.2 million associated with the acquisition of six properties and 44 developments placed in service since January 1, 2014.

Real estate taxes from continuing operations decreased by $905,000 in the second quarter of 2015, compared to the same period in 2014. The decreased real estate tax expense was largely the result of the sale of 79 properties that were not classified within discontinued operations since January 1, 2014.

Service Operations

The following table sets forth the components of net earnings from the Service Operations reportable segment for the three months ended June 30, 2015 and 2014, respectively (in thousands):

34

	Three Months Ended June 30,
	2015			2014
Service Operations:
General contractor and service fee revenue	$	23,901		$	69,512
General contractor and other services expenses	(21,738		)	(63,857		)
Net earnings from Service Operations	$	2,163		$	5,655

Service Operations primarily consist of the leasing, property management, asset management, development, construction management and general contractor services for joint venture properties and properties owned by third parties. Service Operations are heavily influenced by the current state of the economy, as leasing and property management fees are dependent upon occupancy, while construction and development services rely on the expansion of business operations of third-party property owners and joint venture partners. General contractor and service fee revenues, and net earnings from Service Operations, decreased during the three months ended June 30, 2015 because the three months ended June 30, 2014 included two higher-margin third-party construction projects that have since been substantially completed.

Depreciation and Amortization

Depreciation and amortization expense from continuing operations decreased from $88.5 million during the second quarter of 2014 to $78.3 million for the same period in 2015, primarily as the result of asset dispositions since January 1, 2014 that were not classified within discontinued operations. The reduction to depreciation expense was also driven, to a lesser extent, by shorter-lived assets from previous periods' acquisitions becoming fully depreciated.

Equity in Earnings

Equity in earnings represents our ownership share of net income or loss from investments in unconsolidated companies that generally own and operate rental properties. Equity in earnings decreased from $60.8 million for the three months ended June 30, 2014 to $15.1 million for the same period in 2015. During the three months ended June 30, 2015, two of our unconsolidated joint ventures sold properties for which we recorded $12.0 million to equity in earnings for our share of the net gains. During the three months ended June 30, 2014, one of our unconsolidated joint ventures sold its sole property, an office tower in Atlanta, Georgia, and we recorded $58.4 million to equity in earnings for our share of the net gain.

Gain on Sale of Properties - Continuing Operations

Effective April 1, 2014, we early adopted Accounting Standards Update ("ASU") No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity ("ASU 2014-08"), which resulted in fewer real estate sales being classified within discontinued operations. The $107.4 million recognized as gain on sale of properties in continuing operations for the three months ended June 30, 2015 is comprised of the gain from the sale of a portfolio of 51 light industrial buildings located primarily in the Midwest that were sold on April 8, 2015. These properties did not meet the criteria for inclusion in discontinued operations under ASU 2014-08.

The $70.3 million recognized as gains on sale of properties in continuing operations for the three months ended June 30, 2014 was primarily comprised of the gain from the sale of a portfolio of six office properties in Cincinnati, Ohio as well as two smaller industrial properties. These properties did not meet the criteria for inclusion in discontinued operations under ASU 2014-08.

General and Administrative Expenses

General and administrative expenses consist of two components. The first component includes general corporate expenses, and the second component includes the indirect operating costs not allocated to, or absorbed by, the development or Rental Operations of our wholly-owned properties or our Service Operations. The indirect operating

35

costs that are either allocated to, or absorbed by, the development or Rental Operations of our wholly owned properties, or our Service Operations, are primarily comprised of employee compensation, including related costs such as benefits and wage-related taxes, but also include other ancillary costs such as travel and information technology support. Total indirect operation costs, prior to any allocation or absorption, and general corporate expenses are collectively referred to as our overall pool of overhead costs.

Those indirect costs not allocated to or absorbed by these operations are charged to general and administrative expenses. We regularly review our total overhead cost structure relative to our leasing, development and construction volume and adjust the level of total overhead, generally through changes in our level of staffing in various functional departments, as necessary in order to control overall general and administrative expense.

General and administrative expenses increased from $10.4 million for the second quarter of 2014 to $19.2 million for the same period in 2015. The following table sets forth the factors that led to the increase in general and administrative expenses (in millions):

General and administrative expenses - three-month period ended June 30, 2014	$	10.4
Decrease to overall pool of overhead costs (1)	(6.9		)
Overhead restructuring charges (2)	7.2
Decreased absorption of costs by wholly owned leasing and development activities (3)	1.2
Decreased allocation of costs to Service Operations and Rental Operations (4)	7.3
General and administrative expenses - three-month period ended June 30, 2015	$	19.2

(1) Our total pool of overhead costs decreased between periods, largely due to lower salary and related costs, as the result of workforce reductions executed primarily in connection with the significant decrease in our investment in office properties that occurred in connection with the Suburban Office Portfolio Sale in early April 2015.

(2) We recognized approximately $7.2 million of overhead restructuring charges, primarily related to severance costs, during the three months ended June 30, 2015, related to the workforce reductions that took place during the period.

(3) A lower volume of development activity during the three months ended June 30, 2015 resulted in a lower level of absorption of overhead costs compared to the three months ended June 30, 2014. We capitalized $5.2 million and $6.1 million of our total overhead costs to leasing and development, respectively, for consolidated properties during the three months ended June 30, 2015, compared to capitalizing $4.3 million and $8.2 million of such costs, respectively, for the three months ended June 30, 2014. Combined overhead costs capitalized to leasing and development totaled 26.3% and 29.6% of our overall pool of overhead costs for the three months ended June 30, 2015 and 2014, respectively.

(4) The decrease in allocation of costs to Service Operations and Rental Operations resulted from a lower volume of third-party construction projects during the three months ended June 30, 2015 as well as a lower allocation of property management and maintenance expenses to Rental Operations due to significantly decreasing our investment in office properties in early April 2015.

Debt Extinguishment

During the three months ended June 30, 2015, we repurchased $431.2 million of our outstanding unsecured notes. These repurchases were executed primarily in connection with a tender offer that was completed in early April 2015. We also repaid certain secured loans prior to their scheduled maturity dates during the three months ended June 30, 2015. We recognized a total loss on debt extinguishment of $82.7 million from these transactions during the three months ended June 30, 2015, which included make-whole payments, repurchase premiums, prepayment premiums and the write-off of unamortized deferred financing costs.

The loss on debt extinguishment for the three months ended June 30, 2014, was $139,000.

Interest Expense

Interest expense allocable to continuing operations decreased from $51.4 million in the second quarter of 2014 to $43.0 million in the second quarter of 2015. The decrease was primarily due to the repayment of $1.02 billion of outstanding debt during the three months ended June 30, 2015 as well as due to a lower overall weighted average cost of borrowing than in 2014.

36

We capitalized $3.8 million of interest costs during the three months ended June 30, 2015 compared to $4.3 million during the three months ended June 30, 2014.

Discontinued Operations

The property-specific components of earnings that are classified as discontinued operations include rental revenues, rental expenses, real estate taxes, allocated interest expense and depreciation expense, as well as the net gain or loss on the disposition of the properties. The financial results for 61 real estate properties, which were classified as held-for-sale at March 31, 2015 and sold on April 1, 2015, were included in discontinued operations and were classified as such subsequent to the adoption of ASU 2014-08. We sold one property during the three months ended March 31, 2015, which was classified as held-for-sale and included in discontinued operations prior to the adoption of ASU 2014-08.

The operations of 74 buildings were classified as discontinued operations for both the three months ended June 30, 2015 and June 30, 2014. These 74 buildings consist of 16 industrial, 56 office, and two medical office properties. As a result, we classified operating income, before gain on sales, of $36,000 and $5.5 million in discontinued operations for the three months ended June 30, 2015 and 2014, respectively.

Of the properties included in discontinued operations, 61 were sold during three months ended June 30, 2015 and two were sold during 2014. The gains on disposal of these properties, and related income tax impact, are also reported in discontinued operations, as presented in Note 11 to the consolidated financial statements included in this Report.

Comparison of Six Months EndedJune 30, 2015 to Six Months EndedJune 30, 2014

Rental and Related Revenue

The following table sets forth rental and related revenue from continuing operations by reportable segment for the six months endedJune 30, 2015 and 2014, respectively (in thousands):

	Six Months Ended June 30,
	2015		2014
Rental and related revenue:
Industrial	$	283,115	$	261,554
Medical Office	80,302		68,264
Office	48,826		77,565
Other	4,368		6,043
Total rental and related revenue from continuing operations	$	416,611	$	413,426
Rental and Related Revenue from Discontinued Operations	32,164		59,403
Total Rental and Related Revenue from Continuing and Discontinued Operations	$	448,775	$	472,829

The following factors contributed to the increase in rental and related revenue from continuing operations:

• We acquired six properties, of which five were industrial and one was medical office, and placed 44 developments in service from January 1, 2014 to June 30, 2015, which provided incremental revenues of $26.6 million in the six months endedJune 30, 2015, as compared to the same period in 2014.

• Increased occupancy within our same property portfolio was the primary reason for the remaining increase in rental and related revenues from continuing operations. Average commencement occupancy in our same property portfolio increased by 2.0% from the six months ended June 30, 2014.

• Partially offsetting the aforementioned increases was the sale of 79 properties that did not meet the criteria for inclusion within discontinued operations, since January 1, 2014, which resulted in a $35.7 million decrease in rental and related revenue from continuing operations in the six months endedJune 30, 2015, as compared to the same period in 2014.

37

Rental Expenses and Real Estate Taxes

The following table sets forth rental expenses and real estate taxes from continuing operations by reportable segment for the six months endedJune 30, 2015 and 2014, respectively (in thousands):

	Six Months Ended June 30,
	2015		2014
Rental expenses:
Industrial	$	29,787	$	30,643
Medical Office	16,241		16,141
Office	16,187		24,165
Other	4,003		3,313
Total rental expenses from continuing operations	$	66,218	$	74,262
Rental Expenses from Discontinued Operations	8,971		16,631
Total Rental Expenses from Continuing and Discontinued Operations	$	75,189	$	90,893
Real estate taxes:
Industrial	$	43,259	$	39,030
Medical Office	9,195		7,848
Office	5,448		9,727
Other	624		1,250
Total real estate tax expense from continuing operations	$	58,526	$	57,855
Real Estate Tax Expense from Discontinued Operations	3,428		6,873
Total Real Estate Tax Expense from Continuing and Discontinued Operations	$	61,954	$	64,728

Overall, rental expenses from continuing operations decreased by $8.0 million in the six months endedJune 30, 2015, compared to the same period in 2014, primarily as the result of the sale of 79 properties since January 1, 2014, which did not meet the criteria to be classified within discontinued operations.

Overall, real estate taxes from continuing operations increased by $671,000 in the six months endedJune 30, 2015, compared to the same period in 2014. The increased real estate tax expense was largely the result of increased tax rates and assessments across certain of our markets, partially offset by the impact of the sale of 79 properties since January 1, 2014, which did not meet the criteria to be classified within discontinued operations.

Service Operations

The following table sets forth the components of net earnings from the Service Operations reportable segment for the six months endedJune 30, 2015 and 2014, respectively (in thousands):

	Six Months Ended June 30,
	2015			2014
Service Operations:
General contractor and service fee revenue	$	76,722		$	125,332
General contractor and other services expenses	(68,762		)	(111,128		)
Net earnings from Service Operations	$	7,960		$	14,204

General contractor and service fee revenues, and net earnings from Service Operations, decreased during the six months endedJune 30, 2015 because the six months endedJune 30, 2014 included two higher-margin third-party construction projects that have since been substantially completed.

Depreciation and Amortization

Depreciation and amortization expense decreased from $176.8 million during the first six months of 2014 to $160.2 million for the same period in 2015, primarily as the result of asset dispositions since January 1, 2014 that were not

38

classified within discontinued operations. The reduction to depreciation expense was also driven, to a lesser extent, by shorter-lived assets from previous periods' acquisitions becoming fully depreciated.

Equity in Earnings

Equity in earnings decreased from $63.1 million in the first six months of 2014 to $21.4 million for the same period in 2015. During the six months ended June 30, 2015 three of our unconsolidated joint ventures sold properties, for which we recorded $13.5 million to equity in earnings for our share of the net gains. During the six months ended June 30, 2014, one of our unconsolidated joint ventures sold its sole property, an office tower in Atlanta, Georgia, and we recorded $58.4 million to equity in earnings for our share of the net gain.

Gain on Sale of Properties - Continuing Operations

Effective April 1, 2014, we early adopted ASU 2014-08, which resulted in fewer real estate sales being classified within discontinued operations. The $130.9 million recognized as gain on sale of properties in continuing operations for the six months endedJune 30, 2015 is comprised of the gains from the sale of a retail property in Pennsylvania, four industrial properties in Minneapolis, MN, six office properties in Cleveland, OH and a portfolio of 51 light industrial buildings located primarily in the Midwest. These properties did not meet the criteria for inclusion in discontinued operations under ASU 2014-08.

The $86.2 million recognized as gain on sale of properties in continuing operations for the six months ended June 30, 2014 is primarily comprised of the gain from the sale of one medical office property, two industrial properties and six office properties. The medical office property, which was sold prior to our early adoption of ASU 2014-08, did not meet the criteria for inclusion in discontinued operations because of our continued involvement through a retained management agreement after the sale. The two industrial and six office properties were sold in the second quarter of 2014 and did not meet the criteria for inclusion in discontinued operations under ASU 2014-08.

General and Administrative Expense

General and administrative expenses increased from $25.1 million for the first six months of 2014 to $36.2 million for the same period in 2015. The following table sets forth the factors that led to the increase in general and administrative expenses from the six months endedJune 30, 2014 to the six months endedJune 30, 2015 (in millions):

General and administrative expenses - six months ended June 30, 2014	$	25.1
Decrease to overall pool of overhead costs (1)	(6.5		)
Overhead restructuring charges (2)	7.2
Decreased absorption of costs by wholly owned leasing and development activities (3)	3.3
Decreased allocation of costs to Service Operations and Rental Operations (4)	7.1
General and administrative expenses - six months ended June 30, 2015	$	36.2

(1) Our total pool of overhead costs decreased between periods, largely due to lower salary and related costs, as the result of workforce reductions executed primarily in connection with the significant decrease in our investment in office properties that occurred in connection with the Suburban Office Portfolio Sale in early April 2015.

(2) We recognized approximately $7.2 million of overhead restructuring charges, primarily related to severance costs, during the six months ended June 30, 2015, related to the workforce reductions that took place during the period,

(3) A lower volume of development activity during the three months ended June 30, 2015 resulted in a lower level of absorption of overhead costs during the six months ended June 30, 2015 compared to the six months ended June 30, 2014. We capitalized $14.2 million and $9.7 million of our total overhead costs to leasing and development, respectively, for consolidated properties during the six months ended June 30, 2015, compared to capitalizing $12.6 million and $14.6 million of such costs, respectively, for the six months ended June 30, 2014. Combined overhead costs capitalized to leasing and development totaled 27.3% and 31.5% of our overall pool of overhead costs for 2015 and 2014, respectively.

(4) The decrease in allocation of costs to Service Operations and Rental Operations resulted from a lower volume of third-party construction projects during the six months ended June 30, 2015 as well as a lower allocation of property management and maintenance expenses to Rental Operations due to significantly decreasing our investment in office properties in early April 2015.

39

Debt Extinguishment

During the six months ended June 30, 2015, we repurchased $431.2 million of our outstanding unsecured notes. These repurchases were primarily the result of a tender offer that was completed in early April 2015. We also repaid certain secured loans prior to their scheduled maturity dates during six months ended June 30, 2015. We recognized a total loss on debt extinguishment of $82.7 million from these transactions during the six months ended June 30, 2015, which included make-whole payments, repurchase premiums, prepayment premiums as well as the write-off of unamortized deferred financing costs.

The loss on debt extinguishment for the same period in 2014 was $139,000.

Interest Expense

Interest expense allocable to continuing operations decreased from $103.3 million in the first six months of 2014 to $92.6 million in the first six months of 2015. The decrease was primarily due to the repayment of $991.2 million of outstanding debt during the six months ended June 30, 2015 as well as due to a lower overall weighted average cost of borrowing.

We capitalized $6.9 million of interest costs during the six months ended June 30, 2015 compared to $8.5 million during the six months ended June 30, 2014.

Discontinued Operations

The operations of 74 buildings were classified as discontinued operations for both the six months ended June 30, 2015 and June 30, 2014. These 74 buildings consist of 16 industrial, 56 office and two medical office properties. As a result, we classified operating income, before gain on sales, of $10.2 million and $9.4 million in discontinued operations for the six months ended June 30, 2015 and 2014, respectively.

Of the properties included in discontinued operations, 62 were sold during the first six months of 2015 and 12 were sold during the first six months of 2014 (61 of the properties sold during 2015 were classified within discontinued operations subsequent to the April 1, 2014 adoption of ASU 2014-08). The gains on disposal of these properties, and related income tax impact, are also reported in discontinued operations, as presented in Note 11 to the consolidated financial statements.

Liquidity and Capital Resources

Sources of Liquidity

We expect to meet our short-term liquidity requirements over the next 12 months primarily through working capital, net cash provided by operating activities and proceeds received from real estate dispositions. Our short-term liquidity requirements include payments of dividends and distributions as well as the capital expenditures needed to maintain our current real estate assets. We had no outstanding borrowings on the Partnership's $1.2 billion unsecured line of credit at June 30, 2015.

In addition to our existing sources of liquidity, we expect to meet long-term liquidity requirements, such as scheduled mortgage and unsecured debt maturities, property acquisitions, financing of development activities and other capital improvements, through multiple sources of capital including operating cash flow, proceeds from property dispositions, term loans and through accessing the public debt and equity markets.

40

Rental Operations

Cash flows from Rental Operations is our primary source of liquidity and provides a stable source of cash flow to fund operational expenses. We believe that this cash-based revenue stream is substantially aligned with revenue recognition (except for items such as periodic straight-line rental income accruals and amortization of above or below market rents) as cash receipts from the leasing of rental properties are generally received in advance of, or a short time following, the actual revenue recognition.

Our industry is subject to a number of risks related to general economic conditions, including reduced occupancy, tenant defaults and bankruptcies and potential reduction in rental rates upon renewal or re-letting of properties, any of which would result in reduced cash flow from operations.

Unsecured Debt and Equity Securities

We use the Partnership's unsecured line of credit (which is guaranteed by the General Partner) as a temporary source of capital to fund development activities, acquire additional rental properties and provide working capital.

At June 30, 2015, we had on file with the SEC an automatic shelf registration statement on Form S-3 relating to the offer and sale, from time to time, of an indeterminate amount of debt and equity securities. Equity securities are offered and sold by the General Partner, and the net proceeds of such offerings are contributed to the Partnership in exchange for additional General Partner Units or Preferred Units. From time to time, we expect to issue additional securities under this automatic shelf registration statement to fund the repayment of long-term debt upon maturity and for other general corporate purposes.

The General Partner currently has an at the market equity program that allows it to issue new common shares from time to time, with an aggregate offering price of up to $175.0 million. During the six months ended June 30, 2015, the General Partner issued 233,000 common shares pursuant to its at the market offering program, generating gross proceeds of approximately $5.0 million and, after deducting commissions and other costs, net proceeds of approximately $4.8 million. The General Partner has a capacity of $126.3 million remaining under its current at the market equity program.

The Partnership has issued debt securities pursuant to certain indentures and related supplemental indentures, which also require us to comply with financial ratios and other covenants regarding our operations. We were in compliance with all such covenants, as well as applicable covenants under our unsecured line of credit, at June 30, 2015.

Sale of Real Estate Assets

We regularly work to identify, consider and pursue opportunities to dispose of non-strategic properties on an opportunistic basis and on a basis that is generally consistent with our strategic plans. Our ability to dispose of such properties on favorable terms, or at all, is dependent upon a number of factors including the availability of credit to potential buyers to purchase properties at prices that we consider acceptable. Although we believe that we have demonstrated our ability to generate significant liquidity through the disposition of non-strategic properties, potential future adverse changes to general market and economic conditions could negatively impact our further ability to dispose of such properties.

We generated cash from proceeds from the sale of land and depreciable property totaling $1.31 billion during the six months ended June 30, 2015.

Transactions with Unconsolidated Joint Ventures

Transactions with unconsolidated joint ventures also provide a source of liquidity. From time to time we will sell properties to unconsolidated joint ventures, while retaining a continuing interest in that entity, and receive proceeds commensurate to those interests that we do not own. Additionally, unconsolidated joint ventures will from time to time obtain debt financing or sell properties and will then distribute to us, and our joint venture partners, all or a portion of the proceeds from such transactions. During the six months ended June 30, 2015, our share of sale and debt financing distributions from unconsolidated joint ventures totaled $67.0 million.

41

Uses of Liquidity

Our principal uses of liquidity include the following:

• property investment;

• leasing/capital costs;

• dividends and distributions to shareholders and unitholders;

• long-term debt maturities;

• opportunistic repurchases of outstanding debt and preferred stock; and

• other contractual obligations.

Property Investment

It is our strategy, through new developments and, to a lesser extent, acquisitions to continue to increase our investment concentration in industrial properties while, through selective dispositions, reducing our investment concentration in suburban office properties in certain markets. Pursuant to this strategy, we evaluate development and acquisition opportunities based upon our market outlook, including general economic conditions, supply and long-term growth potential. Our ability to make future property investments, along with being dependent upon identifying suitable development and acquisition opportunities, is also dependent upon our continued access to our longer-term sources of liquidity, including issuances of debt or equity securities as well as generating cash flow by disposing of selected properties.

Leasing/Capital Costs

Tenant improvements and lease-related costs pertaining to our initial leasing of newly completed space, or vacant space in acquired properties, are referred to as first generation expenditures. Such first generation expenditures for tenant improvements are included within "development of real estate investments" in our Consolidated Statements of Cash Flows, while such expenditures for lease-related costs are included within "other deferred leasing costs."

Cash expenditures related to the construction of a building's shell, as well as the associated site improvements, are also included within "development of real estate investments" in our Consolidated Statements of Cash Flows.

Tenant improvements and leasing costs to re-let rental space that we previously leased to tenants are referred to as second generation expenditures. Building improvements that are not specific to any tenant but serve to improve integral components of our real estate properties are also second generation expenditures. One of the principal uses of our liquidity is to fund the second generation leasing/capital expenditures of our real estate investments.

The following table summarizes our second generation capital expenditures by type of expenditure, as well as capital expenditures for the development of real estate investments and for other deferred leasing costs (in thousands):

	Six Months Ended June 30,
	2015		2014
Second generation tenant improvements	$	14,697	$	24,475
Second generation leasing costs	13,984		18,573
Building improvements	2,190		1,319
Total second generation capital expenditures	$	30,871	$	44,367
Development of real estate investments	$	109,617	$	226,575
Other deferred leasing costs	$	22,302	$	14,980

We capitalized $14.2 million and $12.6 million of overhead costs related to leasing activities, including both first and second generation leases, during the six months endedJune 30, 2015 and 2014, respectively. We capitalized $9.7 million and $14.6 million of overhead costs related to development activities, including both development and tenant improvement projects on first and second generation space, during the six months endedJune 30, 2015 and

42

2014, respectively. Combined overhead costs capitalized to leasing and development totaled 27.3% and 31.5% of our overall pool of overhead costs for the six months endedJune 30, 2015 and 2014, respectively. Further discussion of the capitalization of overhead costs can be found herein, in the discussion of general and administrative expenses in the Comparison of Six Months Ended June 30, 2015 to Six Months Ended June 30, 2014 section of Management's Discussion and Analysis of Financial Condition and Results of Operations as well as in the Critical Accounting Policies section of Management's Discussion and Analysis of Financial Condition and Results of Operations in our combined Annual Report on Form 10-K for the year ended December 31, 2014 as filed with the SEC on February 20, 2015.

In addition to the capitalization of overhead costs discussed above, we also capitalized $6.9 million and $8.5 million of interest costs in the six months endedJune 30, 2015 and 2014, respectively.

The following table summarizes our second generation capital expenditures by reportable operating segment (in thousands):

	Six Months Ended June 30,
	2015		2014
Industrial	$	20,905	$	24,225
Medical Office	632		788
Office	9,304		18,855
Non-reportable segments	30		499
Total	$	30,871	$	44,367

Both our first and second generation expenditures vary significantly between leases on a per square foot basis, dependent upon several factors including the product type, the nature of a tenant's operations, the specific physical characteristics of each individual property and the market in which the property is located.

Dividend and Distribution Requirements

The General Partner is required to meet the distribution requirements of the Internal Revenue Code of 1986, as amended (the "Code"), in order to maintain its REIT status. We paid dividends or distributions of $0.17 per common share or Common Unit in the first and second quarters of 2015, and the General Partner's board of directors declared dividends or distributions of $0.17 per common share or Common Unit for the third quarter of 2015. Our future dividends or distributions will be declared at the discretion of the General Partner's board of directors and will be subject to our future capital needs and availability.

Debt Maturities

Debt outstanding at June 30, 2015 had a face value totaling $3.5 billion with a weighted average interest rate of 5.13% and maturities at various dates through 2028. Of this total amount, we had $2.7 billion of unsecured debt, $777.7 million of secured debt and no balance on our unsecured line of credit at June 30, 2015. Scheduled principal amortization and maturities of such debt totaled $991.2 million for the six months ended June 30, 2015.

The following table is a summary of the scheduled future amortization and maturities of our indebtedness at June 30, 2015 (in thousands, except percentage data, and including debt related to real estate assets that are classified as held-for-sale on the Consolidated Balance Sheets):

43

	Future Repayments

	$	67,899	$	3,391,644	$	3,459,543	5.13	%

We anticipate generating capital to fund our debt maturities by using undistributed cash generated from our Rental Operations and property dispositions and by raising additional capital from future debt or equity transactions.

Repurchases of Outstanding Debt

To the extent that it supports our overall capital strategy, we may purchase certain of our outstanding unsecured debt prior to its stated maturity.

In March 2015, the Partnership commenced a tender offer (the "Tender Offer") to purchase, for a combined aggregate purchase price (exclusive of accrued and unpaid interest) of up to $500.0 million, certain of its outstanding series of unsecured notes. A portion of the proceeds from the Suburban Office Portfolio Sale were used to fund this Tender Offer, which resulted in the repurchase of notes having a face value of $424.9 million, for a cash payment of $500.0 million. The repurchase was completed on April 3, 2015.

In May 2015, we repurchased unsecured notes with a face value of $6.3 million, for a cash payment of $7.1 million. These notes had a stated interest rate of 6.50% and an effective rate of 6.08%.

Historical Cash Flows

Cash and cash equivalents were $20.3 million and $21.2 million at June 30, 2015 and 2014, respectively. The following table highlights significant changes in net cash associated with our operating, investing and financing activities (in millions):

	Six Months Ended June 30,
	2015			2014
General Partner
Net Cash Provided by Operating Activities	$	175.7		$	204.0
Net Cash Provided by (Used for) Investing Activities	$	1,018.5		$	(129.8	)
Net Cash Used for Financing Activities	$	(1,191.9	)	$	(72.3	)
Partnership

Net Cash Provided by (Used for) Investing Activities	$	1,018.5		$	(129.8	)
Net Cash Used for Financing Activities	$	(1,191.9	)	$	(72.3	)

44

Operating Activities

The receipt of rental income from Rental Operations continues to be our primary source of operating cash flows. The decrease in cash flows from operations noted in the table above was due to lower cash flows from our Rental Operations as the result of the major dispositions completed in early April 2015.

Investing Activities

Investing activities are one of the primary uses of our liquidity. Development and acquisition activities typically generate additional rental revenues and provide cash flows for operational requirements. Highlights of significant cash sources and uses are as follows:

• During the six months ended June 30, 2015, we paid cash of approximately $20.9 million and $25.6 million for real estate and undeveloped land acquisitions, compared to $85.2 million and $11.8 million, respectively, for real estate and undeveloped land acquisitions in the same period in 2014.

• Real estate development costs were $109.6 million during the six months ended June 30, 2015, compared to $226.6 million for the same period in 2014.

• Sales of land and depreciated property provided $1.31 billion in net proceeds for the six months ended June 30, 2015, compared to $213.0 million for the same period in 2014.

• For the six months ended June 30, 2015, we received $67.0 million in capital distributions from unconsolidated joint ventures, compared to $40.3 million during the same period in 2014.

Financing Activities

The following items highlight some of the factors that account for the difference in net cash flow related to financing activities in the first six months of 2015, compared to the same period in 2014:

• For the six months ended June 30, 2015, we repaid the $106.0 million of net borrowings on the Partnership's unsecured line of credit, compared to a paying down $28.0 million of net borrowings for the same period in 2014.

• During the six months ended June 30, 2015, the General Partner repaid fifteen secured loans, which included early repayment premiums of $4.2 million for six loans that were repaid prior to their scheduled maturity dates, for cash payments totaling $201.9 million, compared to repaying six secured loans totaling $82.2 million during the same period in 2014.

• During the six months ended June 30, 2015, the General Partner repaid a $250.0 million senior unsecured note at its maturity date. The General partner also repurchased unsecured notes, primarily through the Tender Offer, for cash payments totaling $508.3 million, which included repurchase premiums, early repayment premiums and transaction costs of $77.1 million. There were no repayments or repurchases during the six months ended June 30, 2014.

• Changes in book overdrafts are classified as financing activities within our Consolidated Statements of Cash Flows. There were book overdrafts of $2.4 million at June 30, 2015, compared to $20.1 million at June 30, 2014.

• During the six months ended June 30, 2015, the General Partner issued 233,000 common shares for net proceeds of approximately $4.8 million, compared to 11.0 million common shares for net proceeds of $191.1 million during the same period in 2014.

• During the six months ended June 30, 2014, the General Partner repurchased preferred shares, among all series outstanding during the period, in the open market. In total, the General Partner repurchased preferred shares having a redemption value of $18.8 million for $17.7 million. There were no such repurchases during the six months ended June 30, 2015.

Contractual Obligations

Aside from changes in long-term debt, there have not been material changes in our outstanding commitments since December 31, 2014, as previously discussed in our 2014 Annual Report on Form 10-K.

Off Balance Sheet Arrangements - Investments in Unconsolidated Companies

We analyze our investments in unconsolidated joint ventures to determine if they meet the criteria for classification as a variable interest entity (a "VIE") and would require consolidation. We (i) evaluate the sufficiency of the total equity 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 the end of each reporting period, we re-assess our conclusions as to which, if any, party within the VIE is considered the primary beneficiary. To the extent that our joint ventures do not qualify as VIEs, we further assess each joint venture partner's substantive participating rights to determine if the venture should be consolidated.

We have equity interests in unconsolidated partnerships and limited liability companies that primarily own and operate rental properties and hold land for development. These unconsolidated joint ventures are primarily engaged in the operations and development of industrial, medical office and office real estate properties. These investments provide us with increased market share and tenant and property diversification. The equity method of accounting is used for these investments in which we have the ability to exercise significant influence, but not control, over operating and financial policies. As a result, the assets and liabilities of these entities are not included on our balance sheet. Our investments in and advances to unconsolidated subsidiaries represented approximately 4% of our total assets at both June 30, 2015 and December 31, 2014. Total assets of our unconsolidated subsidiaries were $1.5 billion and $1.6 billion at June 30, 2015 and December 31, 2014, respectively. The combined revenues of our unconsolidated subsidiaries totaled $94.7 million and $120.6 million for the six months ended June 30, 2015 and 2014, respectively.

We have guaranteed the repayment of certain secured and unsecured loans of our unconsolidated subsidiaries. The outstanding balances on the guaranteed portion of these loans totaled $76.3 million at June 30, 2015.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

We are exposed to interest rate changes primarily as a result of our line of credit and our long-term borrowings. Our interest rate risk management objective is to limit the impact of interest rate changes on earnings and cash flows and to lower overall borrowing costs. To achieve our objectives, we borrow primarily at fixed rates. We do not enter into derivative or interest rate transactions for speculative purposes. We have one outstanding swap, which fixes the rate on one of our variable rate loans and is not significant to our financial statements at June 30, 2015.

Our interest rate risk is monitored using a variety of techniques. The table below presents the principal amounts (in thousands and including debt related to real estate assets that are classified as held-for-sale on the Consolidated Balance Sheets) of the expected annual maturities, weighted average interest rates for the average debt outstanding in the specified period, fair values (in thousands) and other terms required to evaluate the expected cash flows and sensitivity to interest rate changes.

Rate at June 30, 2015	N/A			N/A			N/A			N/A			1.34%			N/A			1.34		%

As the above table incorporates only those exposures that existed at June 30, 2015, it does not consider those exposures or positions that could arise after that date. As a result, the ultimate impact of interest rate fluctuations will depend on future exposures that arise, our hedging strategies at that time to the extent we are party to interest rate derivatives and interest rates. Interest expense on our unsecured line of credit, to the extent we have outstanding borrowings, and our variable rate unsecured notes will be affected by fluctuations in the LIBOR indices as well as changes in our credit rating. The interest rate at such point in the future as we may renew, extend or replace our unsecured line of credit will be heavily dependent upon the state of the credit environment.

Part II - Other Information

Item 1. Legal Proceedings

From time to time, we are parties to a variety of legal proceedings and claims arising in the ordinary course of our businesses. While these matters generally are covered by insurance, there is no assurance that our insurance will cover any particular proceeding or claim. We are not subject to any material pending legal proceedings other than routine litigation arising in the ordinary course of business. We presently believe that all of these proceedings to which we were subject as of June 30, 2015, taken as a whole, will not have a material adverse effect on our liquidity, business, financial condition or results of operations.

Item 1A. Risk Factors

In addition to the information set forth in this Report, you also should carefully review and consider the information contained in our other reports and periodic filings that we make with the SEC, including, without limitation the information contained under the caption "Item 1A. Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2014. The risks and uncertainties described in our 2014 Annual Report on Form 10-K are not the only risks that we face. Additional risks and uncertainties not currently known to us, or that we presently deem to be immaterial, also may materially adversely affect our business, financial condition and results of operations.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

(a) Unregistered Sales of Equity Securities

None

(b) Use of Proceeds

None

(c) Issuer Purchases of Equity Securities

From time to time, we repurchase our securities under a repurchase program that initially was approved by the General Partner's board of directors and publicly announced in October 2001 (the "Repurchase Program").

On January 28, 2015, the General Partner's board of directors adopted a resolution that amended and restated the Repurchase Program and delegated authority to management to repurchase a maximum of $100.0 million of the General Partner's common shares, $500.0 million of the Partnership's debt securities and $500.0 million of the General Partner's preferred shares, subject to the prior notification of the Chairman of the Finance Committee of the board of directors of planned repurchases within these limits (the "January 2015 Resolutions"). We did not repurchase any equity securities through the Repurchase Program during the six months ended June 30, 2015 and the maximum amounts set forth under the January 2015 Resolutions for the repurchase of common shares and preferred shares are remaining in the Repurchase Program. There is $492.9 million remaining for the repurchases of debt securities.

Pursuant to the separate authorization of the Tender Offer by the General Partner's board of directors, the Partnership repurchased notes having a face value of $424.9 million, for a cash payment of $500.0 million in early April 2015.

Item 3. Defaults upon Senior Securities

During the period covered by this Report, we did not default under the terms of any of our material indebtedness.

Item 4. Mine Safety Disclosures

Not applicable.

Item 5. Other Information

49

During the period covered by this Report, there was no information required to be disclosed by us in a Current Report on Form 8-K that was not so reported, nor were there any material changes to the procedures by which our security holders may recommend nominees to the General Partner's board of directors.

New Accounting Pronouncement (Notes)

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

New Accounting Pronouncements, Policy [Policy Text Block]

New Accounting Pronouncements

Revenue Recognition

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). ASU 2014-09 is a comprehensive revenue recognition standard that will supersede nearly all existing GAAP revenue recognition guidance as well as impact the existing GAAP guidance governing the sale of nonfinancial assets. The standard’s core principle is that a company will recognize revenue when it satisfies performance obligations, by transferring promised goods or services to customers, in an amount that reflects the consideration to which the company expects to be entitled in exchange for fulfilling those performance obligations. In doing so, companies will need to exercise more judgment and make more estimates than under existing GAAP guidance.

ASU 2014-09 will be effective for public entities for annual and interim reporting periods beginning after December 15, 2017 and early adoption is permitted in periods ending after December 15, 2016. The changes to the effective date and early adoption are still subject to final approval. ASU 2014-09 allows for either recognizing the cumulative effect of application (i) at the start of the earliest comparative period presented (with the option to use any or all of three practical expedients) or (ii) at the date of initial application, with no restatement of comparative periods presented.

We have not yet selected a transition method nor have we determined the effect of ASU 2014-09 on our consolidated financial statements.

Consolidation

In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis ("ASU 2015-02"). ASU 2015-02 makes targeted amendments to the current consolidation guidance and ends the deferral granted to investment companies from applying the existing variable interest entity guidance. ASU 2015-02 will be effective for public entities for annual and interim reporting periods beginning after December 15, 2015 with early adoption allowed in any interim period. We have not yet selected a transition method and are currently assessing the effect of ASU 2015-02 on our consolidated financial statements.

Debt Issuance Costs

In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"). ASU 2015-03 will require that debt issuance costs related to a recognized debt liability, which are currently presented as deferred charges (assets), be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. ASU 2015-03 will be effective for financial statements issued for fiscal years beginning after December 15, 2015, and for interim periods within those fiscal years. We do not expect ASU 2015-03 to have a material effect on our consolidated financial statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

General Basis of Presentation

General Basis of Presentation

The interim consolidated financial statements included herein have been prepared by Duke Realty Corporation (the "General Partner") and Duke Realty Limited Partnership (the "Partnership"). In this Report, unless the context indicates otherwise, 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 2014 year-end consolidated balance sheet data included in this Quarterly Report on Form 10-Q (this "Report") was derived from the audited financial statements in the combined Annual Report on Form 10-K of the General Partner and the Partnership for the year ended December 31, 2014, but does not include all disclosures required by accounting principles generally accepted in the United States of America ("GAAP"). The financial statements have been prepared in accordance with GAAP for interim financial information and in accordance with Rule 10-01 of Regulation S-X of the Securities Exchange Act of 1934, as amended. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenue and expenses during the reporting period. Our actual results could differ from those estimates and assumptions. These financial statements should be read in conjunction with Management's Discussion and Analysis of Financial Condition and Results of Operations included herein and the consolidated financial statements and notes thereto included in the combined Annual Report on Form 10-K of the General Partner and the Partnership for the year ended December 31, 2014.

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"). 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. Simultaneously, the Partnership completed the acquisition of Duke Associates, a full-service commercial real estate firm operating in the Midwest whose operations began in 1972.

The General Partner is the sole general partner of the Partnership, owning approximately 99.0% of the common partnership interests of the Partnership ("General Partner Units") at June 30, 2015. The remaining 1.0% 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 Fifth 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"), to the extent the Partnership has issued Preferred Units.

As of June 30, 2015, we owned and operated a portfolio primarily consisting of industrial, medical office and office properties and provide real estate services to third-party owners. Substantially all of our Rental Operations (see Note 10) are conducted through the Partnership. We conduct our Service Operations (see Note 10) 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. The consolidated financial statements include our accounts and the accounts of our majority-owned or controlled subsidiaries.

Segment Reporting

Reportable Segments

We had four reportable operating segments at June 30, 2015, the first three of which consist of the ownership and rental of (i) industrial, (ii) medical office and (iii) office real estate investments. The operations of our industrial, medical office and office properties, along with our retail properties, are collectively referred to as "Rental Operations." Properties not included in our reportable segments, which do not by themselves meet the quantitative thresholds for separate presentation as a reportable segment, are referred to as non-reportable Rental Operations. 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.

Revenues by Reportable Segment

The following table shows the revenues for each of the reportable segments, as well as a reconciliation to consolidated revenues, for the three and six months endedJune 30, 2015 and 2014, respectively (in thousands):

Supplemental Performance Measure

Property level net operating income on a cash basis ("PNOI") is the non-GAAP supplemental performance measure that we use to evaluate the performance of, and to allocate resources among, the real estate investments in the reportable and operating segments that comprise our Rental Operations. PNOI for our Rental Operations segments is comprised of rental revenues from continuing operations less rental expenses and real estate taxes from continuing operations, along with certain other adjusting items (collectively referred to as "Rental Operations revenues and expenses excluded from PNOI," as shown in the following table). Additionally, we do not allocate interest expense, depreciation expense and certain other non-property specific revenues and expenses (collectively referred to as "Non-Segment Items," as shown in the following table) to our individual operating segments.

We evaluate the performance of our Service Operations reportable segment using net income or loss, as allocated to that segment ("Earnings from Service Operations").

The following table shows a reconciliation of our segment-level measures of profitability to consolidated income from continuing operations before income taxes for the three and six months endedJune 30, 2015 and 2014, respectively (in thousands and excluding discontinued operations):

The most comparable GAAP measure to PNOI is income from continuing operations before income taxes. PNOI excludes expenses that materially impact our overall results of operations and, therefore, should not be considered as a substitute for income from continuing operations before income taxes or any other measures derived in accordance with GAAP. Furthermore, PNOI may not be comparable to other similarly titled measures of other companies.

Discontinued Operations and Assets Held for Sale

Discontinued Operations and Assets Held-for-Sale

Discontinued Operations

Beginning with our adoption of ASU 2014-08 on April 1, 2014, discontinued operations presentation applies only to disposals representing a strategic shift that has (or will have) a major effect on an entity’s operations and financial results (e.g., a disposal of a major geographical area, a major line of business, a major equity method investment or other major parts of an entity).

On April 1, 2015, we completed the Suburban Office Portfolio Sale that had been under agreement for sale since late January 2015. Because of the size of this disposition, and the fact that it represented our exit from the office product type in four geographic markets, we determined that the disposition represented a strategic shift that would have a major effect on our operations and financial results. As such, the in-service properties in this portfolio met the criteria to be classified within discontinued operations. As the result of its classification within discontinued operations, the in-service assets and liabilities of this portfolio are required to be presented as held-for-sale for all prior periods presented in our Consolidated Balance Sheets.

The following table illustrates the number of sold or held-for-sale properties included in, or excluded from, discontinued operations:

	Held-for-Sale at June 30, 2015	Sold through June 30, 2015	Sold in 2014	Total
Industrial	0	5	11	16
Medical Office	0	1	1	2
Office	0	56	0	56
Total properties included in discontinued operations	0	62	12	74
Properties excluded from discontinued operations	9	62	17	88
Total properties sold or classified as held-for-sale	9	124	29	162

For the properties that were classified in discontinued operations, we allocated 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.

The following table illustrates the operational results of the buildings reflected in discontinued operations for the six months endedJune 30, 2015 and 2014, respectively (in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,

Capital expenditures on a cash basis for the six months endedJune 30, 2015 and 2014 were $7.4 million and $9.9 million, respectively, related to properties classified within discontinued operations.

The following table illustrates the General Partner's share of the income attributable to common shareholders from continuing operations and discontinued operations, reduced by the allocation of income between continuing and discontinued operations to the Limited Partner Units, for the six months endedJune 30, 2015 and 2014, respectively (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2015		2014		2015		2014
Income from continuing operations attributable to common shareholders	$	57,333	$	120,013	$	94,382	$	118,272

Net income attributable to common shareholders	$	449,380	$	127,688	$	514,624	$	146,371

Allocation of Noncontrolling Interests - Partnership

Substantially all of the income from discontinued operations for all periods presented in the Partnership's Consolidated Statements of Operations and Comprehensive Income is attributable to the common unitholders.

Acquisitions and Dispositions

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.

Acquisitions

We acquired one industrial property during the six months ended June 30, 2015. The following table summarizes the fair value of amounts recognized for each major class of asset and liability (in thousands) for this acquisition:

Real estate assets	$	18,246
Lease related intangible assets	2,001
Total acquired assets	20,247
Other liabilities	206
Total assumed liabilities	206
Fair value of acquired net assets	$	20,041

The leases in the acquired property had an average remaining life at acquisition of approximately 9.2 years.

We have included $77,000 in rental revenues and $57,000 in income from continuing operations during the six months ended June 30, 2015 for the property since its date of acquisition.

Fair Value Measurements

The fair value estimates used in allocating the aggregate purchase price of an acquisition among the individual components of real estate assets and liabilities were determined primarily through calculating the "as-if vacant" value of a building, using the income approach, and relied significantly upon internally determined assumptions. We have determined that these estimates primarily rely 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 for acquisition activity during the six months ended June 30, 2015 are as follows:

Discount rate	7.07%
Exit capitalization rate	5.57%
Lease-up period (months)	12
Net rental rate per square foot - Industrial	$4.85

Acquisition-Related Activity

The acquisition-related activity in our consolidated Statements of Operations and Comprehensive Income consisted of transaction costs for completed acquisitions and adjustments to the fair value of contingent consideration from acquisitions after the measurement period is complete.

Dispositions

Dispositions of buildings (see Note 11 for the number of buildings sold as well as for their classification between continuing and discontinued operations) and undeveloped land generated net cash proceeds of $1.31 billion and $213.0 million during the six months endedJune 30, 2015 and 2014, respectively.

On April 1, 2015, we completed the previously announced suburban office portfolio sale (the "Suburban Office Portfolio Sale") to a joint venture with affiliates of Starwood Capital Group, Vanderbilt Partners and Trinity Capital Advisors for approximately $1.07 billion in proceeds and recorded a gain on sale of $398.6 million. The Suburban Office Portfolio Sale includes all of our wholly-owned, in-service suburban office properties located in Nashville, Raleigh, South Florida and St. Louis. The portfolio included approximately 6.7 million square feet across 61 buildings and 57 acres of undeveloped land. One additional office asset currently under construction in Raleigh is expected to be sold upon completion in late 2015.

A portion of the purchase price for the Suburban Office Portfolio Sale was financed through a $200.0 million first mortgage on certain of the properties in the Suburban Office Portfolio that we provided to the seller. The first mortgage matures on December 31, 2016, is prepayable after January 1, 2016, and bears interest at LIBOR plus 1.5%. We have reviewed the creditworthiness of the entities with which we hold this first mortgage and have concluded it is probable that we will be able to collect all amounts due according to its contractual terms.

On April 8, 2015, we completed the sale of 51 non-strategic industrial properties for $270.0 million in proceeds and recorded a gain on sale of $106.6 million. These properties totaled 5.2 million square feet and were located in primarily Midwest markets.

Variable Interest Entity, Not Primary Beneficiary, Disclosures [Abstract]

Consolidation Policy for VIEs

Variable Interest Entities

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 variable interest entities ("VIE"s) 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 own interests in a VIE and 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 and would consolidate the VIE. To the extent we own interest in a VIE, then at each reporting period, we re-assess our conclusions as to which, if any, party within the VIE is considered the primary beneficiary.

There were no consolidated or unconsolidated joint ventures at June 30, 2015 that met the criteria to be considered VIEs. Our maximum loss exposure for guarantees of joint venture indebtedness, for joint ventures that are not VIEs, totaled $76.3 million at June 30, 2015.

Secured Debt

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 2.20% to 3.70%, 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.

During the six months endedJune 30, 2015, we repaid fifteen secured loans, totaling $197.6 million. These loans had a weighted average stated interest rate of 5.32%. Certain of these secured loans were repaid prior to their scheduled maturity date, which resulted in a $3.8 million loss on extinguishment, which included both prepayment penalties as well as the write-off of unamortized deferred loan and mark to market costs.

Unsecured Debt

At June 30, 2015, with the exception of one variable rate term note, 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. The estimated trading values of our fixed rate unsecured debt, depending on the maturity and coupon rates, ranged from 98.00% to 126.00% of face value.

We utilize a discounted cash flow methodology in order to estimate the fair value of our $250.0 million 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. Our estimate of the current market rate for our variable rate term loan was 1.34% and was based primarily upon Level 3 inputs.

In February 2015, we repaid a $250.0 million senior unsecured note at its maturity date. This loan had a stated interest rate of 7.38% and an effective rate of 7.50%.

In April 2015, the Partnership completed a tender offer (the "Tender Offer") to purchase, for a combined aggregate purchase price (exclusive of accrued and unpaid interest) of up to $500.0 million, certain of its outstanding series of unsecured notes. A portion of the proceeds from the Suburban Office Portfolio Sale were used to fund the Tender Offer, which resulted in the repurchase of notes having a face value of $424.9 million, for a cash payment of $500.0 million. The repurchased notes had contractual maturity dates ranging between February 2017 and March 2020 and bore interest at stated rates ranging between 5.95% and 8.25%. Additionally, in May 2015, we repurchased unsecured notes with a face value of $6.3 million, for a cash payment of $7.1 million. These notes had a stated interest rate of 6.50% and an effective rate of 6.08%. The early repayment of unsecured notes, either through the Tender Offer or repurchase, resulted in an aggregate loss on extinguishment of $78.9 million, which included applicable repurchase premiums as well as the write-off of unamortized deferred loan costs.

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 June 30, 2015.

Unsecured Line of Credit

Our unsecured line of credit at June 30, 2015 is described as follows (in thousands):

Description	Maximum Capacity		Maturity Date	Outstanding Balance at June 30, 2015
Unsecured Line of Credit - Partnership	$	1,200,000	January 2019	$	—

The Partnership's unsecured line of credit has an interest rate on borrowings of LIBOR plus 1.05% and a maturity date of January 2019. 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 $1.6 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 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 June 30, 2015, we were in compliance with all covenants under this line of credit.

Net Income (Loss) Per Common Share

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 per common share or Common Unit for the three and six months endedJune 30, 2015 and 2014, respectively (in thousands):
