EXPLANATORY NOTE
This report (the "Report") combines the quarterly reports on Form 10-Q for the period ended September 30, 2016March 31, 2017 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%99.1% of the common partnership interests of the Partnership ("General Partner Units") as of September 30, 2016.March 31, 2017. The remaining 1.0%0.9% of the common partnership interests ("Limited Partner Units" and, together with the General Partner Units, the "Common Units") are owned by limited partners.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.
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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
 
1.    General Basis of Presentation
The interim consolidated financial statements included herein have been prepared by the General Partner and the Partnership. The 20152016 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, 20152016 (the "2015"2016 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 20152016 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 99.0%99.1% of the Common Units at September 30, 2016.March 31, 2017. The remaining 1.0%0.9% of the Common Units are owned by limited partners.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 September 30, 2016,March 31, 2017, we owned and operated a portfolio primarily consisting primarily of industrial and medical office properties and provided real estate services to third-party owners. Substantially all of our Rental Operations (see Note 10)9) are conducted through the Partnership. We conduct our Service Operations (see Note 10)9) 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 RecognitionBusiness Combinations
In May 2014,January 2017, the Financial Accounting Standards Board ("FASB")FASB issued Accounting Standards Update ("ASU") 2014-09,ASU 2017-01, Revenue from Contracts with CustomersBusiness Combinations: Clarifying the Definition of a Business ("ASU 2014-09"2017-01"). ASU 2014-092017-01 provides revised guidance to determine when an acquisition meets the definition of a business or should be accounted for as an asset acquisition, likely resulting in more acquisitions being accounted for as asset acquisitions as opposed to business combinations. Transaction costs are capitalized for asset acquisitions while they are expensed as incurred for business combinations. ASU 2017-01 requires that when substantially all of the fair value of an acquisition is concentrated in a comprehensive revenue recognition standardsingle identifiable asset or a group of similar identifiable assets it does not meet the definition of a business. ASU 2017-01 also revises the definition of a business to include, at a minimum, an input and a substantive process that will supersede nearly all existing GAAP revenue recognition guidance as well as impacttogether significantly contribute to 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 servicesability to customers, increate an amount that reflects the consideration to which an entity expects to be entitled in exchange for fulfilling those performance obligations.output. ASU 2014-092017-01 will be effective, for public entitieson a prospective basis, for annual and interim reporting periods beginning after December 15, 2017, andwith early adoption ispermitted. We adopted ASU 2017-01 prospectively as of January 1, 2017 as permitted in periods ending after December 15, 2016. ASU 2014-09 allows for either full or modified retrospective adoption.
We have begun to evaluate each of our revenue streams under the new standard, andwhich has not had a material impact to the pattern of recognition is not expected to change significantly. Additionally, we have primarily disposed of property and land in all cash transactions with no contingencies and no future involvement in the operations, and therefore, do not expect the new standard to significantly impact the recognition of property and land sales. We have not yet selected a transition method.consolidated financial statements.
ConsolidationRestricted Cash
In February 2015,November 2016, the FASB issued ASU 2015-02,2016-18, Amendments to the Consolidation AnalysisStatement of Cash Flows: Restricted Cash ("ASU 2015-02"2016-18"). ASU 2015-02 made targeted amendments2016-18 requires entities to show the current consolidation guidancechanges in the total of cash and endedrestricted cash in the deferral granted to investment companies from applyingstatement of cash flows.

ASU 2015-03 required that debt issuance costs related to a recognized debt liability2016-15 clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows and how the predominance principle should be presented in the balance sheet as a direct deduction from the carrying amountapplied when cash receipts and cash payments have aspects of that debt liability.more than one class of cash flows. ASU 2015-03 was2016-15 will be effective for us retrospectively for financial statements issued for annual and interim reporting periods beginning after December 15, 2015.2017 with early adoption permitted. We adopteddo not believe ASU 2015-03 during the three months ended March 31, 2016.
Debt issuance costs related to the Partnership's unsecured line of credit continue to be presented as assets in the consolidated balance sheets, as part of escrow deposits and other assets, pursuant to ASU 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements.
Business Combinations
In September 2015, the FASB issued ASU 2015-16, Business Combinations - Simplifying the Accounting for Measurement-Period Adjustments ("ASU 2015-16"). ASU 2015-16 amended the retroactive requirement to apply adjustments made to provisional amounts recognized in2016-15 will have a business combination. The update required that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. ASU 2015-16 was effective for annual and interim periods beginning after December 15, 2015. We adopted ASU 2015-16 during the three months ended March 31, 2016 and it has not had a significantmaterial impact on our consolidated financial statements.

Stock Compensation

In March 2016, the FASB issued ASU 2016-09, Stock Compensation: Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"), which simplifies certain aspects of accounting for share-based payment transactions, including income tax consequences, forfeitures and the classification of amounts paid to taxing authorities when shares are withheld to cover employee tax withholdings for certain stock based compensation plans in the statements of cash flows. ASU 2016-09 was effective for us as of January 1, 2017 and has not had a material impact on our consolidated financial statements.

Leases
In February 2016, the FASB issued ASU 2016-02,Leases ("ASU 2016-02"), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). ASU 2016-02 supersedes existing leasing standards.

ASU 2016-02 requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. ASU 2016-02 also requires that lessors expense certain initial direct costs, which are capitalizable under existing leasing standards, as incurred.

ASU 2016-02 also specifies that payments for certain lease-related services, which are often included in lease agreements, represent "non-lease" components that will become subject to the guidance in ASU 2014-09, Revenue

from Contracts with Customers when ASU 2016-02 becomes effective. We are currently evaluating the materiality, and presentation and disclosure impacts, of this accounting change.

ASU 2016-02 requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. ASU 2016-02 requires lessors to accountwill impact the accounting and disclosure requirements for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financingthe ground leases, and other operating leases. ASU 2016-02 also requires that lessors expense certain initial direct costs, whichleases, where we are capitalizable under existing leasing standards, as incurred.the lessee.

ASU 2016-02 iswill be effective for us retrospectivelyunder a modified retrospective approach for annual and interim reporting periods beginning after December 15, 2018, with early adoption permitted. A set of practical expedients for implementation, which must be elected as a package and for all leases, may also be elected. These practical expedients include relief from re-assessing lease classification at the adoption date for expired or existing leases, although a right-of-use asset and lease liability would still be recorded for such leases. We are currently assessing the method of adoption and the impact that ASU 2016-02 will have on our consolidated financial statements.statements but have tentatively concluded that we will apply the practical expedients.
Stock Based Compensation
Revenue Recognition
In March 2016,May 2014, the FASB issued ASU 2016-09,2014-09, Improvements to Employee Share-Based AccountingRevenue from Contracts with Customers ("ASU 2016-09"2014-09"). ASU 2016-09 requires2014-09 is a comprehensive revenue recognition standard that will supersede nearly all excess tax benefitsexisting GAAP revenue recognition guidance as well as impact the existing GAAP guidance governing the sale of non-financial 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 tax deficiencies related to stock based compensation arrangements must be recognizedmake more estimates than under existing GAAP guidance.
ASU 2014-09 also created guidance governing the sale of non-financial assets with customers and non-customers with the only difference in the incometreatment of these transactions being presentation in the statement as they occur as opposedof operations (revenue and expense is reported when the sale is to a customer and net gain or loss is reported when the current guidance where excess tax benefits are recorded in equity. ASU 2016-09 also allows entitiessale is to make an accounting policy election to either continue to estimate forfeituresa non-customer). Based on stock based compensation arrangements or to account for forfeitures as they occur. ASU 2016-09 is effective for annual and interim reporting periods beginning after December 15, 2016the nature of our business, we believe that our property sales represent transactions with early adoption permitted. We do not believe ASU 2016-09 will have a material impact on our consolidated financial statements.
Statement of Cash Flowsnon-customers.
In August 2016,February 2017, the FASB issued ASU 2016-15,2017-05, StatementOther Income: Gains and Losses from the Derecognition of Cash FlowsNonfinancial Assets ("(“ASU 2016-15"2017-05”). ASU 2016-15 clarifies2017-05 provides guidance on how entities should classify certain cash receiptsrecognize sales, including partial sales, of nonfinancial assets (and in-substance nonfinancial assets) to noncustomers. ASU 2017-05 requires the seller to recognize a full gain or loss in a partial sale of nonfinancial assets, to the extent control is not retained. Any noncontrolling interest retained by the seller would, accordingly, be measured at fair value.
Both ASU 2014-09 and cash payments on the statement of cash flows and how the predominance principle shouldASU 2017-05 will be applied when cash receipts and cash payments have aspects of more than one class of cash flows. ASU 2016-15 is effective for us retrospectivelypublic entities for annual and interim reporting periods beginning after December 15, 2017 withand early adoption permitted.is permitted in periods ending after December 15, 2016. ASU 2014-09 and ASU 2017-05 allow for either full or modified retrospective ("cumulative effect") adoption. Both standards must be adopted concurrently. We have tentatively concluded that we will adopt both ASU 2014-09 and ASU 2017-05 using the cumulative effect method.

We have evaluated each of our revenue streams under ASU 2014-09 and determined that our revenues that will be impacted by this standard primarily include construction and development fees charged to third parties, fees for services performed for unconsolidated joint ventures and sales of real estate. We expect that the amount and timing of revenue recognition from these revenue streams referenced above will be generally consistent with our current measurement and pattern of recognition. In addition, sales of real estate and the pattern of recognition is not expected to change significantly. We have primarily disposed of property and land in all cash transactions with no

contingencies and no future involvement in the operations, and therefore, do not believeexpect ASU 2016-15 will have a material2017-05 to significantly impact on our consolidated financial statements.the recognition of property and land sales.
3.    Reclassifications
Certain amounts in the accompanying consolidated financial statements for 2015,2016, including the change in presentation of deferred financing coststax payments on stock-based compensation awards pursuant to ASU 2015-03,2016-09, have been reclassified to conform to the 20162017 consolidated financial statement presentation.
4.    Variable Interest Entities
Partnership
AsDue to the result offact that the adoption of ASU 2015-02, which stipulates that limited partnerships (and similar entities) where the limited partnersLimited Partners do not have kick out rights, or substantive participating or kick-out rights, are VIEs, we determined that the Partnership is a VIE. Prior to the adoption of ASU 2015-02,variable interest entity ("VIE"). Because the General Partner consolidated the Partnership pursuant to the voting interest model. We concluded that, because it holds majority ownership and exercises control

over every aspect of the Partnership's operations, the General Partner ishas been determined as the primary beneficiary of the Partnership and, as such, will continue to consolidatetherefore, 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 also an obligation of the Partnership.

Unconsolidated 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 guaranteed returns, protection against losses, or capping of residual returns within the group 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 our partner does not have substantive participating rights. Control is further demonstrated by our ability to unilaterally make significant operating decisions, refinance debt and sell the assets of the joint venture without the consent of the non-managing entity and the inability of the non-managing entity to remove us from our role as the managing entity. Consolidated joint ventures that are not VIEs are not significant in any period presented in these consolidated financial statements.

There were no unconsolidated joint ventures, in which we have any recognized assets or liabilities or have retained any economic exposure to loss at September 30, 2016March 31, 2017 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 $52.7$63.1 million at September 30, 2016.March 31, 2017.



5.    Acquisitions and Dispositions

Acquisitions and dispositions for the periods presented were completed in accordance with our strategy to reposition our investment concentration among the product types and markets in which we operate. Theoperate and to increase our overall investments in quality industrial projects. 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. Transaction costs related to asset acquisitions are capitalized and transaction costs related to business combinations and dispositions are expensed.

Acquisitions

We acquired twosix properties during the ninethree months ended September 30, 2016, which included a property received as partMarch 31, 2017. We determined that the six properties acquired during the three months ended March 31, 2017 did not meet the revised definition of a non-cash distribution in connection withbusiness as the dissolutionresult of an unconsolidated joint venture. early-adopting ASU 2017-01 and, accordingly, we treated them as asset acquisitions as opposed to business combinations.

The following table summarizes amounts recognized for each major class of asset and liabilityassets (in thousands) for these acquisitions during the ninethree months ended September 30, 2016:March 31, 2017:
Real estate assets$72,824
$108,924
Lease related intangible assets6,427
6,497
Fair value of acquired net assets$79,251
$115,421
AcquiredThe leases in the acquired properties had ana weighted average remaining life at acquisition of approximately 8.95.2 years.

We have included $2.1 million in rental revenues and a net loss of $28,000 in continuing operations during the nine months ended September 30, 2016 for the properties since their respective dates of acquisition.

Distribution of Joint Venture Properties
Included in our property acquisitions for the nine months ended September 30, 2016 was an industrial property that we received as part of a non-cash distribution of properties from Duke/Hulfish LLC ("Duke/Hulfish"), a 20%

owned unconsolidated joint venture. On June 30, 2016, as part of a plan of dissolution, Duke/Hulfish distributed its ownership in seven properties to our partner in the joint venture while distributing its ownership interest in one property to us. We also received $2.8 million in cash from the joint venture in order to balance the value of the distributions received in accordance with the applicable ownership percentages. As the result of this dissolution transaction, we recognized a gain equal to the excess of the fair value of the one property distributed to us, plus the cash that we received, over the carrying value of our 20% investment in the eight properties that were distributed from Duke/Hulfish (both to us and our partner). The computation of this gain is shown as follows (in thousands):
Fair value of one property received in non-cash distribution$63,000
Cash received at dissolution2,760
Carrying value of investment in properties distributed to partners(35,063)
Gain on dissolution of unconsolidated company$30,697

In connection with the dissolution of Duke/Hulfish, and the sale of its final property to a third party in July 2016, we recognized promote income (additional incentive-based cash distributions from the joint venture, in excess of our 20% ownership interest) totaling $26.3 million for the nine months ended September 30, 2016.
     
Fair Value Measurements
     
TheWe determine the fair value estimates used in allocating the aggregate purchase price of an acquisition, to the extent accounted for as a business combination, among the individual components of real estate assets and liabilities were determinedasset acquisitions primarily through calculating the "as-if vacant" value of a building, using thean income approach, and reliedwhich relies 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 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 ninethree months ended September 30, 2016March 31, 2017 are as follows: 
LowHighLowHigh

Dispositions
Dispositions of buildings (see Note 1110 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 $369.1$103.1 million and $1.53 billion$57.4 million during the ninethree months ended September 30,March 31, 2017 and 2016, and 2015, respectively.

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 2.50%3.00% to 3.30%3.90%, 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 ninethree months ended September 30, 2016,March 31, 2017, we repaid fivetwo loans, totaling $346.4$15.9 million, which had a weighted average stated interest rate of 5.90%5.72%.

Unsecured Debt

At September 30, 2016,March 31, 2017, with the exception of onethe $250.0 million variable rate term note described below, all of our unsecured debt bore interest at fixed rates and primarily consisted of unsecured notes that are publicly traded. We utilized broker estimates in estimating the fair value of our fixed rate unsecured debt. Our unsecured notes are thinly traded and, in certain cases, the broker estimates were not based upon comparable transactions. The broker estimates took into account any recent trades within the same series of our fixed rate unsecured debt, comparisons to recent trades of other series of our fixed rate unsecured debt, trades of fixed rate unsecured debt from companies with profiles similar to ours, as well as overall economic conditions. We reviewed these broker estimates for reasonableness and accuracy, considering whether the estimates were based upon market participant assumptions within the principal and most advantageous market and whether any other observable inputs would be more accurate indicators of fair value than the broker estimates. We concluded that the broker estimates were representative of fair value. We have determined that our estimation of the fair value of our fixed rate unsecured debt was primarily based upon level 3 inputs. The estimated trading values of our fixed rate unsecured debt, depending on the maturity and coupon rates, ranged from 103.00%96.00% to 137.00%127.00% of face value.
During the nine months ended September 30, 2016, we issued $375.0 millionThe indentures (and related supplemental indentures) governing our outstanding series of senior unsecured notes that bear interestalso require us to comply with financial ratios and other covenants regarding our operations. We were in compliance with all such financial covenants at a stated interest rate of 3.25%, have an effective interest rate of 3.36%, and mature on June 30, 2026. A portion of these proceeds were used to repurchase, through a tender offer, $72.0 million of our 5.95% senior unsecured notes due February 2017 ("5.95% Senior Unsecured Notes"), for a cash payment of $74.5 million in June 2016. In July 2016, we redeemed the remaining $203.0 million of 5.95% Senior Unsecured Notes for a cash payment of $209.0 million. Together, the repurchase and the redemption resulted in an $8.7 million loss on debt extinguishment, which included repurchase premiums, redemption premiums and the write-off of unamortized deferred financing costs.March 31, 2017.


We utilize a discounted cash flow methodology in order to estimate the fair value of our $250.0 million variable rate term loan. Our estimate of the current market rate for our variable rate term loan was 1.68%1.99% and was based primarily upon level 3 inputs. To the extent that credit spreads have changed since the origination of this 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 would represent the difference between the book value and the fair value. Our 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 the term loan are the same.

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 September 30, 2016.

Unsecured Line of Credit
Our unsecured line of credit at September 30, 2016March 31, 2017 is described as follows (in thousands):

Unsecured Line of Credit - Partnership$1,200,000
 January 2019 $
$1,200,000
 January 2019 $237,000

The Partnership's unsecured line of credit has an interest rate on borrowings of LIBOR plus 1.05%0.93% (equal to 1.85% for outstanding borrowings at March 31, 2017) and a maturity date of January 2019, (with extension options that could extend the maturity date to January 2020).which may be extended by a year at our option. 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 $1.60 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 September 30, 2016,March 31, 2017, we were in compliance with all financial covenants under this line of credit.
To the extent that there are outstanding borrowings, we utilize a discounted cash flow methodology in order to estimate the fair value of our unsecured line of credit. 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. Our 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 the line of credit are the same. To the extent there are outstanding borrowings, this current market rate is internally estimated and therefore would be primarily based upon a level 3 input.
      
7.    Shareholders' Equity of the General Partner and Partners' Capital of the Partnership
General Partner
During the nine months ended September 30, 2016, the General Partner issued 8.3 million common shares pursuant to its at the market ("ATM") equity program, generating gross proceeds of approximately $216.2 million and, after deducting commissions and other costs, net proceeds of approximately $213.6 million. The proceeds from these offerings were contributed to the Partnership and used to fund development activities and loan repayments.




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 (in thousands):

9.8.    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 basic 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, unitsweighted 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 basic 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):

9.    Segment Reporting
Reportable Segments
We had three reportable operating segments at September 30, 2016,March 31, 2017, the first two of which consist of the ownership and rental of (i) industrial and (ii) medical office real estate investments. BeginningProperties not included in 2016, our office properties are no longer presented as a separate reportable segment, as they no longersegments, which do not by themselves meet the quantitative thresholds for separate presentation andas a reportable segment, are generally referred to as part of our non-reportable Rental Operations. Our non-reportable Rental Operations primarily include our office properties. The operations of our industrial and medical office properties, as well as our non-reportable Rental Operations, are collectively referred to as "Rental Operations." Our third 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.

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 (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.

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. There were no additional properties classified as discontinued operations during the nine months ended September 30, 2016 and, as such, no interest expense was allocated to discontinued operations during that period.

As the result of changes in our intended use or plans for sale of certain of our undeveloped land holdings, we recognized land impairment charges of $12.1 million for the nine months ended September 30, 2016. The various land holdings written down to fair value totaled 174 acres. The fair value of the land upon which we recognized impairment charges was estimated based on asset-specific offers to purchase and comparable transactions. Our valuation estimates primarily relied upon level 3 inputs.

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 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;

Business Overview
The General Partner and Partnership collectively specialize in the ownership, management and development of industrial and medical office real estate.
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 20152016 Annual Report.
At September 30, 2016,March 31, 2017, we:
Owned or jointly controlled 566568 primarily industrial and medical office properties, of which 545538 properties with 131.9 million square feet were in service and 2130 properties with 7.211.0 million square feet were under development. The 545538 in-service properties were comprised of 486496 consolidated properties with 118.6120.7 million square feet and 5942 jointly controlled unconsolidated properties with 13.311.3 million square feet. The 2130 properties under development consisted of 2027 consolidated properties with 6.510.2 million square feet and onethree jointly controlled unconsolidated propertyproperties with 708,000727,000 square feet.
Owned directly, or through ownership interests in unconsolidated joint ventures (with acreage not adjusted for our percentage ownership interest), approximately 2,6002,150 acres of land and controlled approximately 1,600 acres through purchase options.
Our overall strategy is to continue to increase our investment in quality industrial properties in both existing and select new markets and to continue to increase our investment in on-campus or hospital affiliated medical office properties.

We had three reportable operating segments at September 30, 2016,March 31, 2017, the first two of which consist of the ownership and rental of (i) industrial and (ii) medical office real estate investments. BeginningProperties not included in 2016, our office properties are no longer presented as a separate reportable segment, as they no longersegments, which do not by themselves meet the quantitative thresholds for separate presentation andas a reportable segment, are generally referred to as part of our non-reportable Rental Operations. Our non-reportable Rental Operations primarily include our office properties. The operations of our industrial and medical office properties, as well as our non-reportable Rental Operations, are collectively referred to as "Rental Operations."

The third reportable segment consists of various real estate services such as property management, asset management, maintenance, leasing, development, general contractorcontracting 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 aforementioned 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 of rental properties, including properties classified within both continuing and discontinued operations, at September 30,March 31, 2017 and 2016, and 2015, respectively:

* 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 twosix buildings during the ninethree months ended September 30, 2016March 31, 2017 and two17 buildings during the year ended December 31, 2015.2016. 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):

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 sold 22seven wholly owned buildings during the ninethree months ended September 30, 2016March 31, 2017 and 15332 wholly owned buildings during the year ended December 31, 2015.2016.

Supplemental Performance Measures
In addition to net income 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) 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 (loss) 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 (loss) 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 (in thousands):

September 30, 2015, was primarily the result of $82.6 million in losses on debt extinguishment that were recognized during the second quarter of 2015. Development properties being placed in service, operational improvements and lower interest expense also contributed to the increased FFO in 2016 as compared to the corresponding periods in 2015.

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. 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.

Note 109 to the consolidated financial statements included in Part I, Item 1 of this Report shows a calculation of our PNOI for the three and nine months ended September 30, 2015March 31, 2017 and 2016 and provides a reconciliation of PNOI for our Rental Operations segments to income from continuing operations before income taxes.
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 September 30, 2016,March 31, 2017, as those properties that have beenwere owned and in operation throughoutin-service as of January 1, 2016, and held as in-service properties through the twenty-four months ended September 30, 2016.end of the reporting periods shown. In addition to excluding properties that have not been owned and in operation forwere sold or identified as held-for-sale through the twenty-four months ended September 30, 2016,end of the reporting periods shown, we have also excludedexclude properties from our same-property portfolio where revenues from individual lease buyouts in excess of $250,000 have been recognized.recognized in either the full calendar year 2016 or year-to-date calendar year 2017.

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 109 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:

(1) Includes the total square feet of the consolidated properties that are in the same property population as well as 4.5 million square feet of space for unconsolidated joint ventures, which represents our ratable share of the 9.4 million total square feet of space for buildings owned by unconsolidated joint ventures that are in the same property population.(1) Includes the total square feet of the consolidated properties that are in the same property population as well as 4.5 million square feet of space for unconsolidated joint ventures, which represents our ratable share of the 9.4 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 September 30, 2016 and 2015 for tenants in occupancy in properties in the same property population.

The following factors contributed to the increase in rental and related revenue from continuing operations:
We acquired four23 properties and placed 4127 developments in service from January 1, 20152016 to September 30, 2016,March 31, 2017, which provided incremental revenues of $13.0$17.3 million in the thirdfirst quarter of 2016,2017, as compared to the same period in 2015.2016.
Rental and related revenue from continuing operations includes lease termination fees, which relate to specific tenants who pay a fee to terminate their lease obligation before the end of the contractual lease term.The overall increase in rental and related revenue from continuing operations included an increase of $9.4 million in termination fees compared to the three months ended March 31, 2016.
Increased occupancy and rental rates within our same-property portfolio also resulted in ancontributed to the increase to rental and related revenue from continuing operations. Average commencement occupancy in our same-property portfolio increased by 0.9%1.5% from the three months ended September 30, 2015.March 31, 2016.
The sale of 11339 properties since January 1, 2015,2016, which did not meet the criteria to be classified within discontinued operations, resulted in a decrease of $15.4$11.0 million to rental and related revenue from continuing operations in the three months ended September 30, 2016,March 31, 2017, as compared to the same period in 2015,2016, which partially offset the aforementioned increases to rental and related revenues.

Rental expenses from continuing operations decreased by $4.1$4.0 million during the three months ended September 30, 2016,March 31, 2017, compared to the same period in 2015.2016. The decrease to rental expenses was primarily the result of sales of office properties, which have higher utility and other operating costs relative to industrial properties, that did not meet the criteria to be classified within discontinued operations.

Real estate tax expense from continuing operations increased by $3.6$2.8 million during the three months ended September 30, 2016,March 31, 2017, compared to the same period in 2015.2016. The increase to real estate tax expense was mainly the result of industrial developments placed in service from January 1, 20152016 to September 30, 2016March 31, 2017 and increases in real estate taxes on our existing base of properties. These increases to real estate tax expense were partially offset by the impact of property sales that 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 (in thousands):
 Three Months Ended September 30,
 2016 2015
Service Operations:   
General contractor and service fee revenue$19,351
 $33,599
General contractor and other services expenses(17,182) (29,694)
Net earnings from Service Operations$2,169
 $3,905

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 September 30, 2016 as the result of lower third-party construction activity due to focusing our resources on wholly-owned development projects.


Depreciation and Amortization
Depreciation and amortization expense from continuing operations increased from $79.9$77.8 million for the three months ended September 30, 2015March 31, 2016 to $80.7$81.6 million for the same period in 20162017 primarily as the result of 41the 23 properties acquired and the 27 developments placed in service since January 1, 2015.2016. The impact of acquired properties and developments placed in service was partially offset by property dispositions that did not meet the criteria to be classified within discontinued operations.
Equity in Earnings (Loss)
Equity in earnings (loss) represents our ownership share of net income or loss from investments in unconsolidated companies that generally own and operate rental properties. Equity in earnings increaseddecreased from a loss of $5.1$21.9 million for the three months ended September 30, 2015March 31, 2016 to earnings of $12.0$4.7 million for the same period in 2016.2017. During the three months ended September 30, 2016,March 31, 2017, we recorded $8.7$1.8 million to equity in earnings related to our share of the gainsgain on sale of one joint venture buildings and undeveloped land. The loss duringbuilding. During the three months ended September 30, 2015 was primarily caused byMarch 31, 2016, we recorded $14.0 million to equity in earnings for our share of the recognitionnet gains from the sale of a $7.9 million impairment charge to write down the carrying valuefour office properties in one of our investment in an unconsolidated joint venture to fair value after we concluded during the period that a decline in the value of that investment, which was not temporary, had taken place.ventures.
Gain on Sale of Properties - Continuing Operations
The $82.7$37.0 million recognized as gain on sale of properties in continuing operations for the three months ended September 30, 2016March 31, 2017 is the result of the gain from the sale of 13seven properties. These properties did not meet the criteria for inclusion in discontinued operations.

The $71.3$15.6 million recognized as gain on sale of properties in continuing operations for the three months ended September 30, 2015March 31, 2016 was the result of the gain from the sale of 16three properties. These properties did not meet the criteria for inclusion in discontinued operations.

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 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 $11.3$18.1 million for the three months ended September 30, 2015March 31, 2016 to $12.5$19.2 million for the same period in 2016.2017. 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 September 30, 2015$11.3
 Increase to overall pool of overhead costs1.0
 Increased absorption of costs by wholly owned leasing and development activities (1)(1.2)
 Decreased allocation of costs to Service Operations and Rental Operations1.4
General and administrative expenses - three-month period ended September 30, 2016$12.5
General and administrative expenses - three-month period ended March 31, 2016$18.1
 Decrease to overall pool of overhead costs(1.1)
 Increased absorption of costs by wholly owned leasing and development activities (1)(0.5)
 Decreased allocation of costs to Service Operations and Rental Operations (2)2.7
General and administrative expenses - three-month period ended March 31, 2017$19.2
(1) We capitalized $4.0$5.3 million and $8.1$8.3 million of our total overhead costs to leasing and development, respectively, for consolidated properties during the three months ended September 30, 2016,March 31, 2017, compared to capitalizing $4.1$6.8 million and $6.8

$6.3 million of such costs, respectively, for the three months ended September 30, 2015.March 31, 2016. Combined overhead costs capitalized to leasing and development totaled 33.7%33.3% and 31.3%31.4% of our overall pool of overhead costs for the three months ended September 30,March 31, 2017 and 2016, respectively.
(2) The decrease in allocation of costs to Service Operations and 2015, respectively.Rental Operations resulted from a lower volume of third-party construction projects during the three months ended March 31, 2017 as well as a lower allocation of property management and maintenance expenses to Rental Operations due to significantly decreasing our investment in office properties through 2016 disposition activities.

Interest Expense
Interest expense allocable to continuing operations decreased from $41.6$37.7 million for the three months ended September 30, 2015March 31, 2016 to $34.6$30.5 million for the three months ended September 30, 2016.March 31, 2017. The decrease to interest expense from continuing operations was primarily due to interest savings from reducing totalleverage and refinancing higher rate indebtedness by $444.9 million since June 30, 2015 as well as due to a lower overall weighted average cost of borrowing than in 2015.during 2016.
We capitalized $3.5$4.2 million and $4.4$5.7 million of interest costs for the three months ended September 30, 2016March 31, 2017 and 20152016, respectively.
Acquisition-Related Activity
Acquisition-related activity decreased to an expense of $7,000 for the three months ended September 30, 2016 from an expense of $5.7 million for the three months ended September 30, 2015. Substantially all of the activity during the three months ended September 30, 2015 was related to a charge to earnings that resulted from an increase to the estimated fair value of the contingent consideration from a previous period's acquisition.
Debt Extinguishment
During the three months ended September 30, 2016, we redeemed the remaining $203.0 million of the outstanding 5.95% Senior Unsecured Notes. This redemption resulted in a loss on debt extinguishment of $6.2 million, which consisted of redemption premiums and the write-off of unamortized deferred financing costs.
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 operations of 62
We had no buildings were classified as discontinued operations for both the three months ended September 30, 2016March 31, 2017 and September 30, 2015. These 62 buildings consist of five industrial, 56 office, and one medical office properties. As a result, weMarch 31, 2016. The amounts classified operating income, before gain on sales, of $377,000 in discontinued operations for the three months ended September 30,March 31, 2016 comparedwere comprised of true-up activity related to an operating loss, before gain on2015 property sales of $43,000 inthat were classified as discontinued operationsoperations. There was no true-up activity for the three months ended September 30, 2015.
The gains on disposal of these properties are also reported in discontinued operations, as presented in Note 11 to the consolidated financial statements included in this Report.March 31, 2017.

 32,171
Total Rental and Related Revenue from Continuing and Discontinued Operations$609,906
 $649,720
The following factors contributed to the decrease in rental and related revenue from continuing operations:
The sale of 113 properties, since January 1, 2015, which did not meet the criteria for inclusion within discontinued operations, resulted in a decrease of $50.6 million to rental and related revenue from continuing operations in the nine months ended September 30, 2016, as compared to the same period in 2015.
We acquired four properties and placed 41 developments in service from January 1, 2015 to September 30, 2016, which provided incremental revenues of $28.5 million in the nine months ended September 30, 2016, as compared to the same period in 2015, which partially offset the overall decrease in rental and related revenue from continuing operations.
Increased occupancy and rental rates within our same property portfolio also partially offset the impact of dispositions on rental and related revenue from continuing operations.

 $89,673
Overall, rental expenses from continuing operations decreased by $15.3 million in the nine months endedSeptember 30, 2016, compared to the same period in 2015. The decrease to rental expenses from continuing operations was primarily the result of sales of office properties, which have higher utility and other operating costs relative to industrial properties, that did not meet the criteria to be classified within discontinued operations. The impact of this decrease was partially offset by incremental expenses related to developments placed in service.

Overall, real estate tax expense from continuing operations increased by $4.7 million in the nine months ended September 30, 2016, compared to the same period in 2015. The increase to real estate tax expense from continuing operations was caused by the net effect of 41 developments placed in service from January 1, 2015 to September 30, 2016, and by increased real estate taxes for our existing base of properties, both partially offset by the impact of property sales that 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 (in thousands):
 Nine Months Ended September 30,
 2016 2015
Service Operations:   
General contractor and service fee revenue$68,546
 $110,320
General contractor and other services expenses(60,330) (98,455)
Net earnings from Service Operations$8,216
 $11,865

General contractor and service fee revenues, and net earnings from Service Operations, decreased during the nine months ended September 30, 2016 due to less overall third party construction activity as we continue to focus our resources on wholly owned development projects.

Depreciation and Amortization
Depreciation and amortization expense decreased from $240.1 million during the nine months ended September 30, 2015 to $238.6 million for the same period in 2016, primarily as the result of asset dispositions since January 1, 2015 that were not classified within discontinued operations. The impact of asset dispositions was partially offset by new developments being placed in service.
Equity in Earnings
Equity in earnings increased from $16.3 million during the nine months ended September 30, 2015 to $37.4 million for the same period in 2016. During the nine months ended September 30, 2016, we recorded $25.2 million to equity in earnings related to our share of the gains on sale of joint venture buildings and undeveloped land or for sales of our interests in unconsolidated joint ventures. During the nine months ended September 30, 2015, three of our unconsolidated joint ventures sold properties for which we recorded $13.7 million to equity in earnings for our share of the net gains. We also recognized a $7.9 million impairment charge to write down the carrying value of our investment in an unconsolidated joint venture to fair value during the nine months ended September 30, 2015, after we concluded during the period that a decline in the value of that investment was not temporary.
Gain on Dissolution of Unconsolidated Company and Promote Income
As described in Note 5 to the consolidated financial statements included in Part I, Item 1 of this Report, we recognized a $30.7 milliongain and $26.3 million of promote income related to the dissolution of Duke/Hulfish during the nine months ended September 30, 2016.
Gain on Sale of Properties - Continuing Operations
The $137.6 million recognized as gain on sale of properties in continuing operations for the nine months ended September 30, 2016 is comprised primarily of the gains from the sale of 22 properties. These properties did not meet the criteria for inclusion in discontinued operations.
The $202.2 million recognized as gain on sale of properties in continuing operations for the nine months ended September 30, 2015 is primarily comprised of the gains from the sale of 78 properties that did not meet the criteria for inclusion in discontinued operations.

Gain on Land Sales
We recognized $2.4 million of gains on sale of 145 acres of land, compared to $24.1 million of gains on sale of 383 acres of land, for the nine months ended September 30, 2016 and September 30, 2015, respectively.
Impairment Charges

We recognized impairment charges of $12.1 million on 174 acres of land, compared to impairment charges of $7.0 million on 122 acres of land, for the nine months ended September 30, 2016 and September 30, 2015, respectively. These impairment charges were the result of changes in the intended use, or plans for sale, for certain of our investments in undeveloped land.
We also recognized impairment charges of $3.0 million and $864,000 on buildings during the nine months endedSeptember 30, 2016 and September 30, 2015, respectively.
General and Administrative Expense
General and administrative expenses decreased from $47.6 million for the nine months ended September 30, 2015 to $42.2 million for the same period in 2016. The following table sets forth the factors that led to the decrease in general and administrative expenses (in millions):
General and administrative expenses - nine months ended September 30, 2015$47.6
  Decrease to overall pool of overhead costs (1)(10.5)
  Increased absorption of costs by wholly owned leasing and development activities (2)(1.3)
  Decreased allocation of costs to Service Operations and Rental Operations (3)6.4
General and administrative expenses - nine months ended September 30, 2016$42.2
(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 a $1.1 billion office portfolio sale that took place in early April 2015. The nine month period ended September 30, 2015 included $7.4 million of overhead restructuring costs.
(2) We capitalized $16.7 million and $19.4 million of our total overhead costs to leasing and development, respectively, for consolidated properties during the nine months ended September 30, 2016, compared to capitalizing $18.3 million and $16.5 million of such costs, respectively, for the nine months ended September 30, 2015. Combined overhead costs capitalized to leasing and development totaled 32.3% and 28.4% of our overall pool of overhead costs for the nine months ended September 30, 2016 and 2015, respectively.
(3) The decrease in allocation of costs to Service Operations and Rental Operations resulted from a lower volume of third-party construction projects during the nine months ended September 30, 2016 as well as a lower allocation of property management and maintenance expenses to Rental Operations due to significantly decreasing our investment in office properties since early April 2015.
Interest Expense
Interest expense allocable to continuing operations decreased from $134.6 million for the nine months ended September 30, 2015 to $109.5 million for the nine months ended of September 30, 2016. The decrease to interest expense from continuing operations was primarily due to reducing total indebtedness by $1.44 billion since December 31, 2014 as well as due to a lower overall weighted average cost of borrowing than in 2015.
We capitalized $13.0 million of interest costs during the nine months ended September 30, 2016 compared to $11.4 million during the nine months ended September 30, 2015.
Debt Extinguishment
During the nine months ended September 30, 2016, we repurchased $72.0 million of our outstanding 5.95% Senior Unsecured Notes, through a tender offer, prior to their maturity date in February 2017 and redeemed the remaining$203.0 million of the outstanding 5.95% Senior Unsecured Notes after the completion of the tender. Together, the repurchase and the redemption resulted in a total loss on debt extinguishment of $8.7 million, which consisted of repurchase premiums, redemption premiums and the write-off of unamortized deferred financing costs.

During the nine months ended September 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 the nine months ended September 30, 2015. We recognized a total loss on debt extinguishment of $82.6 million from these transactions during the nine months ended September 30, 2015, which included make-whole payments, repurchase premiums, prepayment premiums as well as the write-off of unamortized deferred financing costs.
Acquisition-Related Activity
Acquisition-related activity decreased to an expense of $82,000 during the nine months ended September 30, 2016 from an expense of $7.0 million during the nine months ended September 30, 2015. Substantially all of the activity in 2015 was related to a charge to earnings that resulted from an increase to the estimated fair value of the contingent consideration from a previous period's acquisition.
Discontinued Operations
The operations of 62 buildings were classified as discontinued operations for both the nine months ended September 30, 2016 and September 30, 2015. These 62 buildings consist of five industrial, 56 office and one medical office properties. As a result, we classified operating income, before gain on sales, of $741,000 and $10.5 million in discontinued operations for the nine months ended September 30, 2016 and 2015, respectively. 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 Part I, Item 1 of this Report.

Liquidity and Capital Resources

Sources of Liquidity

We expect to meet our short-term liquidity requirements over the next 12 months, including maturities of indebtedness, payments of dividends and distributions and the capital expenditures needed to maintain our current real estate assets, 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. During the nine months ended September 30, 2016, we also received full repayment of the $200.0 million seller-financed mortgage from the buyers of an office portfolio that we sold in April 2015. We had noa $237.0 million balance outstanding on the Partnership's $1.20 billion unsecured line of credit at September 30, 2016.March 31, 2017.

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.

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 isWe are 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 September 30, 2016,March 31, 2017, 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.securities (including guarantees of the Partnership's debt securities by the General Partner). 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's previous ATM equity program, which allowed it to issue new common shares from time to time, was fully utilized in July 2016. On August 9, 2016, the General Partner entered into a newhas an ATM equity program that allows it to issue new common shares from time to time, with an aggregate offering price of up to $200.0 million. During the ninethree months ended September 30, 2016,March 31, 2017, the General Partner issued a total of 8.3 milliondid not issue any common shares pursuant to both of its ATM equity programs (including 5.1 million common shares under its old program and 3.2 million common shares under its new program) with an average issuance price of $25.92 per share, generating gross proceeds of approximately $216.2 million, and, after deducting commissions and other costs, net proceeds of approximately $213.6 million.program. As of September 30, 2016,March 31, 2017, the new ATM equity program still had $110.1$108.1 million worth of new common shares available to issue.

In June 2016, we issued $375.0 million of senior unsecured notes that bear interest at a stated interest rate of 3.25%, have an effective interest rate of 3.36%, and mature on June 30, 2026.

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 September 30, 2016.March 31, 2017.

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 saleSales of land and depreciable property totaling $369.1provided $103.1 million in net proceeds during the ninethree months ended September 30, 2016.March 31, 2017.
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 ninethree months ended September 30, 2016,March 31, 2017, our share of sale and debt financing distributions from unconsolidated joint ventures totaled $52.5$4.9 million.
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
other contractual obligations.
Property Investment
Our overall strategy is to continue to increase our investment in quality industrial properties in both existing and select new markets and to continue to increase our investment in on-campus or hospital affiliated medical office properties. 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 is dependent upon identifying suitable acquisition and development opportunities, and 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):

The capital expenditures in the table above include the capitalization of internal overhead costs. We capitalized $16.7$5.3 million and $18.3$6.8 million of overhead costs related to leasing activities, including both first and second generation leases, during the ninethree months ended September 30,March 31, 2017 and 2016, and 2015, respectively. We capitalized $19.4$8.3 million and $16.5$6.3 million of overhead costs related to development activities, including both development and

tenant improvement projects on first and second generation space, during the ninethree months ended September 30,March 31, 2017 and 2016, and 2015, respectively. Combined overhead costs capitalized to leasing and development totaled 32.3%33.3% and 28.4%31.4% of our overall pool of overhead costs for the ninethree months ended September 30,March 31, 2017 and 2016, and 2015, respectively. Further discussion of the capitalization of overhead costs can be found herein, in the discussionquarter-to-quarter comparison of general and administrative expenses in the Comparison of Nine Months Ended September 30, 2016 to Nine Months Ended September 30, 2015 section of Management's Discussion and Analysis of Financial Condition and Results of Operationsthis Item 2 as well as in the Critical Accounting Policies section of Management's Discussion and Analysis of Financial Condition and Results of Operations in our 20152016 Annual Report.

In addition to the capitalization of overhead costs, the totals for development of real estate assets in the table above include the capitalization of $13.0$4.2 million and $11.4$5.7 million of interest costs in the ninethree months ended September 30,March 31, 2017 and 2016, and 2015, respectively.

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 Code, in order to maintain its REIT status. We paid regular dividends or distributions of $0.18$0.19 per common share or Common Unit in the first second and third quartersquarter of 2016,2017, and the General Partner's board of directors declared dividends or distributions of $0.19 per common share or Common Unit for the fourthsecond quarter of 2016. Our future dividends or distributions will be2017.

We expect to continue to distribute at least an amount equal to our taxable earnings, to meet the requirements to maintain the General Partner's REIT status, and additional amounts as determined by the General Partner's board of directors. Distributions are declared at the discretion of the General Partner's board of directors and will beare subject to actual cash available for distribution, our futurefinancial condition, capital needsrequirements and availability.such other factors as the General Partner's board of directors deems relevant.

The Partnership's variable rate unsecured notes and unsecured line of credit are both reflected in the table above as maturing in January 2020, based on the ability to exercise a one-year extension option from their stated maturity dates of January 2019. 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.

On October 20, 2016 we redeemed $129.5 million in unsecured notes that had a scheduled maturity in August of 2019.
Repurchases of Outstanding Debt
To the extent that it supports our overall capital strategy, we may purchase some of our outstanding unsecured notes prior to their stated maturities.
During the nine months ended September 30,Contractual Obligations

Aside from repayments of long-term debt, there have not been material changes in our outstanding commitments since December 31, 2016, we issued $375.0 million of senior unsecured notes that bear interest at a stated interest rate of 3.25%, have an effective interest rate of 3.36%, and mature on June 30, 2026. A portion of these proceeds were used to repurchase, through a tender offer, $72.0 million ofas previously discussed in our 5.95% Senior Unsecured Notes, for a cash payment of $74.5 million in June 2016. In July 2016 we redeemed the remaining $203.0 million of the 5.95% Senior Unsecured Notes, for a cash payment of $209.0 million.Annual Report.

Operating Activities

Cash flows from operating activities provide the cash necessary to meet normal operational requirements of our Rental Operations and Service Operations activities. The receipt of rental income from Rental Operations continues to be our primary source of operating cash flows. The increase to cash flow provided by operating activities, compared to the ninethree months ended September 30, 2015,March 31, 2016, was due to improved operational performance, carrying a larger overall portfolio of real estate assets and lower cash paid for interest, as the result of the significant debt repayments or refinancings that took place throughout 2015, newly developed properties being placed in service and improved operational performance.2016.

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 ninethree months ended September 30, 2016,March 31, 2017, we paid cash of approximately $16.0$114.4 million and $77.6$50.4 million, respectively, for real estate and undeveloped land acquisitions, compared to $28.8$27.2 million of undeveloped land acquisitions and $39.9 million, respectively, forno real estate and undeveloped land acquisitions in the same period in 2015.2016.
Real estate development costs were $308.2$112.7 million during the ninethree months ended September 30, 2016,March 31, 2017, compared to $221.2$108.2 million for the same period in 2015.2016. During the three months ended March 31, 2017, we placed five newly completed wholly owned development projects in service and expect to continue with a robust level of new development.
Sales of land and depreciated propertyproperties provided $369.1$103.1 million in net proceeds for the ninethree months ended September 30, 2016,March 31, 2017, compared to $1.53 billion$57.4 million for the same period in 2015.2016.
Second generation tenant improvements, leasing costs and building improvements totaled $39.2$10.4 million for the ninethree months ended September 30, 2016March 31, 2017 compared to $45.7$14.4 million for the same period in 2015.2016.
For the ninethree months ended September 30, 2016,March 31, 2017, we received $52.5$4.9 million in capital distributions from unconsolidated joint ventures, compared to $68.9$29.5 million during the same period in 2015.2016.

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 nine months of 2016, compared to the same period in 2015:significant capital transactions:
For the ninethree months ended September 30, 2016,March 31, 2017, we repaid the $71.0 million ofincreased net borrowings on the Partnership's unsecured line of credit by $189.0 million, compared to the repaymentan increase of $106.0$77.0 million of net borrowings for the same period in 2015.2016.

During the ninethree months ended September 30, 2016,March 31, 2017, we repaid fivetwo secured loans for $346.4$15.9 million. We repaid sixteenone secured loans, which included early repayment premiums of $4.2 millionloan for five loans that were repaid prior to their scheduled maturity dates, for cash payments totaling $213.1$14.4 million during the same period in 2015.2016.
DuringChanges in book overdrafts are classified as financing activities within our consolidated Statements of Cash Flows. Book overdrafts were $20.6 million and $2.5 million for the ninethree months ended September 30,March 31, 2017 and 2016, through both a tender offerrespectively.

Contractual Obligations

Aside from repayments of long-term debt and the issuance of the 2026 Notes described above, there have not been material changes in our outstanding commitments since December 31, 2015, as previously discussed in our 2015 Annual Report.
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 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,limited partners (or similar owning entities) that lack substantive participating or capping of residual returns within the groupkick 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 (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. There were no unconsolidated joint ventures that met the criteria to be a VIE at September 30, 2016.March 31, 2017.
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 and 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 subsidiariesjoint ventures represented approximately 4%3% of our total assets at both September 30, 2016March 31, 2017 and December 31, 2015.2016. Total assets of our unconsolidated subsidiariesjoint ventures were $951.4$734.1 million and $1.4 billion$743.4 million at September 30, 2016March 31, 2017 and December 31, 2015,2016, respectively. The combined revenues of our unconsolidated subsidiariesjoint ventures totaled $97.5$21.5 million and $136.7$36.0 million for the ninethree months ended September 30,March 31, 2017 and 2016, and 2015, respectively.
We have guaranteed the repayment of certain secured and unsecured loans of our unconsolidated subsidiaries.joint ventures. The outstanding balances on the guaranteed portion of these loans totaled $52.7$63.1 million at September 30, 2016.March 31, 2017.
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 September 30, 2016.March 31, 2017.
Our interest rate risk is monitored using a variety of techniques. The table below presents the principal amounts (in thousands) 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.

The Partnership's variable rate unsecured notes and unsecured line of credit are both reflected in the table above as maturing in January 2020, based on the ability to exercise a one-year extension option from their stated maturity dates of January 2019.
As the above table incorporates only those exposures that existed at September 30, 2016,March 31, 2017, 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.
