The 2019 year-end consolidated balance sheet data included in 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, 2019 (the " 2019 Annual Report"), 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 2019 Annual Report. The General Partner was formed in 1985, and we believe that it qualifies as a 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 99.1% of the Common Units at March 31, 2020 . The remaining 0.9% of 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. As of March 31, 2020

Leases [Abstract]
Lessor, Operating Leases [Text Block]	Lease Income Our leases generally include scheduled rent increases, but do not include variable payments based on indexes. Our rental revenue is primarily based on fixed, non-cancelable leases. Our variable rental revenue primarily consists of amounts recovered from lessees for property tax, insurance and common area maintenance ("CAM"). All revenues related to lease and lease-related services are included in, and comprise substantially all of, the caption "Rental and Related Revenue" on the Consolidated Statements of Operations and Comprehensive Income. The components of Rental and Related Revenue are as follows (in thousands): Three Months Ended March 31, 2020 2019 Rental revenue - fixed payments $ 161,608 $ 156,674 Rental revenue - variable payments (1) 57,147 53,291 Rental and related revenue $ 218,755 $ 209,965 (1) Primarily includes tenant recoveries for real estate taxes, insurance and CAM. Accounting for Lease Concessions Granted in Connection with the COVID-19 Outbreak On April 8, 2020, the Financial Accounting Standard Board ("FASB") held a public meeting and shortly afterwards issued a question-and-answer ("Q&A") document which was intended to provide accounting relief for lease concessions related to the COVID-19 pandemic. The accounting relief permits an entity to choose to forgo the evaluation of the enforceable rights and obligations of a lease contract, which is a requirement of Accounting Standards Codification Topic 842, Leases, as long as the total rent payments after the lease concessions are substantially the same, or less than, the total payments previously required by the lease. An entity may account for COVID-19 related lease concessions either (i) as if they were part of the enforceable rights and obligations of the parties under the existing lease contract; or (ii) as a lease modification. To the extent that a rent concession is granted as a deferral of payments, but the total lease payments are substantially the same, lessors are allowed to account for the concession as if no change had been made to the original lease contract. Based on the Q&A, an entity is not required to account for all lease concessions related to the effects of the COVID-19 pandemic under one elected option, however, the entity is required to apply the elected option consistently to leases with similar characteristics and in similar circumstances. Since the COVID-19 pandemic did not start to adversely impact the economic conditions in the United States until late March 2020, we did not provide any COVID-19 related lease concessions to our tenants during the three months ended March 31, 2020 .

Variable Interest Entities

Variable Interest Entities	3 Months Ended

Disclosure Text Block [Abstract]
Consolidation Policy for VIEs	Variable Interest Entities Partnership Due to the fact that the Limited Partners do not have kick out rights, or substantive participating rights, the Partnership is a variable interest entity ("VIE"). Because the General Partner holds majority ownership and exercises control over every aspect of the Partnership's operations, the General Partner has been determined as the primary beneficiary and, therefore, consolidates the Partnership. The assets and liabilities of the General Partner and the Partnership are substantially the same, as the General Partner does not have any significant assets other than its investment in the Partnership. All of the Company's debt is an obligation of the Partnership. Joint Ventures We have equity interests in unconsolidated joint ventures that primarily own and operate rental properties or hold land for development. We consolidate those joint ventures that are considered to be VIEs where we are the primary beneficiary. We analyze our investments in joint ventures to determine if the joint venture is considered a VIE and would require consolidation. We (i) evaluate the sufficiency of the total equity investment at risk, (ii) review the voting rights and decision-making authority of the equity investment holders as a group and whether there are limited partners (or similar owning entities) that lack substantive participating or kick out rights and (iii) establish whether or not 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 interests 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. Consolidated joint ventures that are VIEs are not significant in any period presented in these consolidated financial statements. To the extent that our joint ventures do not qualify as VIEs, they are consolidated if we control them through majority ownership interests or if we are the managing entity (general partner or managing member) and the other partner does not have substantive participating rights. Control is further demonstrated by our ability to unilaterally make significant operating decisions, refinance debt and sell the assets of the joint venture without the consent of the non-managing entity and the inability of the non-managing entity to remove us from our role as the managing entity. Consolidated joint ventures that are not VIEs are not significant in any period presented in these consolidated financial statements. There were no unconsolidated joint ventures, in which we have any recognized assets or liabilities or have retained any economic exposure to loss at March 31, 2020 , that met the criteria to be considered VIEs. Our maximum loss exposure for guarantees of unconsolidated joint venture indebtedness, none of which relate to VIEs, totaled $58.1 million at March 31, 2020 .

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 the markets in which we operate and to increase our overall investments in quality industrial projects. Transaction costs related to asset acquisitions are capitalized and transaction costs related to business combinations and dispositions are expensed. Acquisitions We did not acquire any buildings during the three months ended March 31, 2020 . We paid cash of $76.1 million for building acquisitions during the three months ended March 31, 2019 . Dispositions Dispositions of buildings and undeveloped land generated net cash proceeds of $27.1 million and $1.9 million during the three months ended March 31, 2020 and 2019 , respectively. During the three months ended March 31, 2020 , we collected the remaining $110.0 million

Debt Disclosure [Abstract]
Indebtedness	Indebtedness All debt is issued 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 (in thousands): Book Value at 12/31/2019 Book Value at 3/31/2020 Fair Value at 12/31/2019 Issuances and Assumptions Payments/Payoffs Adjustments to Fair Value Fair Value at 3/31/2020 Fixed rate secured debt $ 32,287 $ 49,789 $ 34,547 $ 18,400 $ (876 ) $ (10,090 ) $ 41,981 Variable rate secured debt 1,900 1,900 1,900 — — — 1,900 Unsecured debt 2,900,000 2,925,000 3,045,485 325,000 (300,000 ) (184,670 ) 2,885,815 Unsecured line of credit — 200,000 — 200,000 — — 200,000 Total $ 2,934,187 $ 3,176,689 $ 3,081,932 $ 543,400 $ (300,876 ) $ (194,760 ) $ 3,129,696 Less: Deferred financing costs 19,422 30,078 Total indebtedness as reported on the consolidated balance sheets $ 2,914,765 $ 3,146,611 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 market rates for all of our current fixed rate secured debt are between 3.00% and 3.60% , 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. In February 2020, one consolidated joint venture obtained an $18.4 million secured loan from a third party financial institution, with a fixed annual interest rate of 3.41% and a maturity date of March 1, 2035. Unsecured Debt At March 31, 2020 , 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 80.00% to 125.00% of face value. In February 2020, we issued $325.0 million of senior unsecured notes bearing interest at a stated interest rate of 3.05% and maturing on March 1, 2050, at 97.35% of par value, resulting in an effective interest rate of 3.19% . Proceeds from the unsecured notes offering were primarily used to repay the $300.0 million of senior unsecured notes due 2022. In connection with the early redemption of these notes, we recognized a loss of $17.8 million consisting of a repayment premium and write-off of deferred financing costs. The indentures (and related supplemental indentures) governing our outstanding series of unsecured notes also require us to comply with financial ratios and other covenants regarding our operations. We were in compliance with all such financial covenants at March 31, 2020 . Unsecured Line of Credit Our unsecured line of credit at March 31, 2020 is described as follows (in thousands): Description Borrowing Capacity Maturity Date Outstanding Balance at March 31, 2020 Unsecured Line of Credit - Partnership $ 1,200,000 January 30, 2022 $ 200,000 The Partnership's unsecured line of credit has an interest rate on borrowings of LIBOR plus 0.875% (equal to 1.81% for our outstanding borrowings at March 31, 2020 ) and has a maturity date of January 30, 2022 , with options to extend until January 30, 2023. Subject to certain conditions, the terms also include an option to increase the facility by up to an additional $800.0 million , for a total of up to $2.00 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 March 31, 2020 , we were in compliance with all financial covenants under this line of credit. We utilize a discounted cash flow methodology in order to estimate the fair value of outstanding borrowings on our unsecured line of credit. To the extent that credit spreads have changed since the origination of the line of credit, the net present value of the difference between future contractual interest payments and future interest payments based on our estimate of a current market rate would represent the difference between the book value and the fair value. This estimate of a current market rate is based upon the rate, considering current market conditions and our specific credit profile, at which we estimate we could obtain similar borrowings. As our credit spreads have not changed appreciably, we believe that the contractual interest rate and the current market rate on any outstanding borrowings on the line of credit are the same. The current market rate is internally estimated and therefore is primarily based upon a level 3 input.

Earnings Per Share [Abstract]
Net Income (Loss) Per Common Share	Net Income per Common Share or Common Unit Basic net income per common share or Common Unit is computed by dividing net income 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 per common share is computed by dividing the sum of net income attributable to common shareholders and the noncontrolling interest in earnings allocable to Limited Partner Units (to the extent the Limited Partner Units are dilutive), less dividends or distributions on participating securities that are anti-dilutive, by the sum of the weighted average number of common shares outstanding and, to the extent they are dilutive, weighted average number of Limited Partner Units outstanding and any potential dilutive securities for the period. Diluted net income per Common Unit is computed by dividing the net income attributable to common unitholders, less dividends or distributions on participating securities that are anti-dilutive, 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 (in thousands): Three Months Ended March 31, 2020 2019 General Partner Net income attributable to common shareholders $ 19,456 $ 44,551 Less: dividends on participating securities (356 ) (388 ) Basic net income attributable to common shareholders $ 19,100 $ 44,163 Add back dividends on dilutive participating securities — — Noncontrolling interest in earnings of common unitholders 170 382 Diluted net income attributable to common shareholders $ 19,270 $ 44,545 Weighted average number of common shares outstanding 368,190 359,139 Weighted average Limited Partner Units outstanding 3,224 3,065 Other potential dilutive shares 456 158 Weighted average number of common shares and potential dilutive securities 371,870 362,362 Partnership Net income attributable to common unitholders $ 19,626 $ 44,933 Less: distributions on participating securities (356 ) (388 ) Basic net income attributable to common unitholders $ 19,270 $ 44,545 Add back distributions on dilutive participating securities — — Diluted net income attributable to common unitholders $ 19,270 $ 44,545 Weighted average number of Common Units outstanding 371,414 362,204 Other potential dilutive units 456 158 Weighted average number of Common Units and potential dilutive securities 371,870 362,362 The following table summarizes the data that is excluded from the computation of net income per common share or Common Unit as a result of being anti-dilutive (in thousands): Three Months Ended March 31, 2020 2019 General Partner and Partnership Other potential dilutive shares or units: Anti-dilutive outstanding potential shares or units under fixed stock option and other stock-based compensation plans — — Anti-dilutive outstanding participating securities 1,647 1,967

Segment Reporting

Segment Reporting	3 Months Ended

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting Reportable Segments As of March 31, 2020 , we had two reportable operating segments, the first consisting of the ownership and rental of industrial real estate investments. Our ongoing investments in new real estate investments are determined largely upon anticipated geographic trends in supply and demand for industrial buildings, as well as the real estate needs of our major tenants that operate on a national level. Our strategic initiatives and our allocation of resources have been historically based upon allocation among product types, which was consistent with our designation of reportable segments, and after having sold nearly all of our office and medical office properties we intend to increase our investment in industrial properties and treat them as a single operating and reportable segment. Properties not included in our reportable segments, because they are not industrial properties and do not by themselves meet the quantitative thresholds for separate presentation as a reportable segment, are generally referred to as non-reportable Rental Operations. Our non-reportable Rental Operations primarily include our remaining office properties and medical office property at March 31, 2020 . The operations of our industrial properties, as well as our non-reportable Rental Operations, are collectively referred to as "Rental Operations." Our second 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." The Service Operations segment is identified as one single operating segment because the lowest level of financial results reviewed by our chief operating decision maker are the results for the Service Operations segment in total. Further, our reportable segments 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 (in thousands): Three Months Ended March 31, 2020 2019 Revenues Rental Operations: Industrial $ 216,952 $ 208,403 Non-reportable Rental Operations 1,528 1,452 Service Operations 7,614 54,964 Total segment revenues 226,094 264,819 Other revenue 275 110 Consolidated revenue $ 226,369 $ 264,929 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 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. The following table shows a reconciliation of our segment-level measures of profitability to consolidated income from continuing operations before income taxes (in thousands and excluding discontinued operations): Three Months Ended March 31, 2020 2019 PNOI Industrial $ 157,061 $ 142,494 Non-reportable Rental Operations 1,819 876 PNOI, excluding all sold properties 158,880 143,370 PNOI from sold properties included in continuing operations 114 5,992 PNOI, continuing operations $ 158,994 $ 149,362 Earnings from Service Operations 1,046 2,378 Rental Operations revenues and expenses excluded from PNOI: Straight-line rental income and expense, net 1,703 5,704 Revenues related to lease buyouts 392 19 Amortization of lease concessions and above and below market rents 2,557 1,262 Intercompany rents and other adjusting items (394 ) 433 Non-Segment Items: Equity in earnings of unconsolidated joint ventures 2,539 4,715 Interest expense (23,494 ) (22,132 ) Depreciation and amortization expense (85,359 ) (75,992 ) Gain on sale of properties 8,937 (163 ) Impairment charges (5,626 ) — Interest and other income, net 1,395 2,758 General and administrative expenses (21,763 ) (21,983 ) Gain on land sales 135 750 Other operating expenses (1,112 ) (2,123 ) Loss on extinguishment of debt (17,806 ) (13 ) Gain on involuntary conversion — 2,259 Non-incremental costs related to successful leases (2,525 ) (2,156 ) Other non-segment revenues and expenses, net (67 ) 75 Income from continuing operations before income taxes $ 19,552 $ 45,153
