EXPLANATORY NOTE
This report (the "Report") combines the quarterly reports on Form 10-Q for the period ended JuneSeptember 30, 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 99.1% of the common partnership interests of the Partnership ("General Partner Units") as of JuneSeptember 30, 2017. The remaining 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. 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.

DUKE REALTY CORPORATION AND DUKE REALTY LIMITED PARTNERSHIP
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
 
1.    General Basis of Presentation
The interim consolidated financial statements included herein have been prepared by the General Partner and the Partnership. The 2016 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, 2016 (the "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 2016 Annual Report.
The General Partner was formed in 1985, and we believe that it qualifies as a REIT under the provisions of the Internal Revenue Code of 1986, as amended (the "Code"). The Partnership was formed on October 4, 1993, when the General Partner contributed all of its properties and related assets and liabilities, together with the net proceeds from an offering of additional shares of its common stock, to the Partnership. Simultaneously, the Partnership completed the acquisition of Duke Associates, a full-service commercial real estate firm operating in the Midwest whose operations began in 1972.
The General Partner is the sole general partner of the Partnership, owning approximately 99.1% of the Common Units at JuneSeptember 30, 2017. The remaining 0.9% of the Common Units are owned by Limited Partners. As the sole general partner of the Partnership, the General Partner has full, exclusive and complete responsibility and discretion in the day-to-day management and control of the Partnership. The General Partner and the Partnership are operated as one enterprise. The management of the General Partner consists of the same members as the management of the Partnership. As the sole general partner with control of the Partnership, the General Partner consolidates the Partnership for financial reporting purposes, and the General Partner does not have any significant assets other than its investment in the Partnership. Therefore, the assets and liabilities of the General Partner and the Partnership are substantially the same.
Limited Partners have the right to redeem their Limited Partner Units, subject to certain restrictions. Pursuant to the Fifth Amended and Restated Agreement of Limited Partnership, as amended (the "Partnership Agreement"), the General Partner is obligated to redeem the Limited Partner Units in shares of its common stock, unless it determines in its reasonable discretion that the issuance of shares of its common stock could cause it to fail to qualify as a REIT. Each Limited Partner Unit shall be redeemed for one share of the General Partner's common stock, or, in the event that the issuance of shares could cause the General Partner to fail to qualify as a REIT, cash equal to the fair market value of one share of the General Partner's common stock at the time of redemption, in each case, subject to certain adjustments described in the Partnership Agreement. The Limited Partner Units are not required, per the terms of the Partnership Agreement, to be redeemed in registered shares of the General Partner.
During the threenine months ended JuneSeptember 30, 2017, we substantially completed the disposition of our medical office portfolio (the "Medical Office Portfolio Disposition", see Note 5) and exited from the medical office product segment. As of JuneSeptember 30, 2017, we owned and operated a portfolio primarily consisting of industrial properties and provided real estate services to third-party owners. Substantially all of our Rental Operations (see Note 9) are conducted through the Partnership. We conduct our Service Operations (see Note 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
Business Combinations
In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business ("ASU 2017-01"). ASU 2017-01 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 single 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 together significantly contribute to the ability to create an output. ASU 2017-01 will be effective, on a prospective basis, for annual and interim reporting periods beginning after December 15, 2017, with early adoption permitted. We adopted ASU 2017-01 prospectively as of January 1, 2017 as permitted under the standard, which has not had a material impact to the consolidated financial statements.
Restricted Cash
In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash ("ASU 2016-18"). ASU 2016-18 requires entities to show the changes in the total of cash and restricted cash in the statement of cash flows. As a result, entities will no longer present transfers between cash and restricted cash in the statement of cash flows. ASU 2016-18 will be effective for us retrospectively for annual and interim reporting periods beginning after December 15, 2017 with early adoption permitted. We do not believe ASU 2016-18 will have a material impact on our consolidated financial statements.
Statement of Cash Flows


In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows ("ASU 2016-15"). ASU 2016-15 clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows and how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. ASU 2016-15 will be effective for us retrospectively for annual and interim reporting periods beginning after December 15, 2017 with early adoption permitted. We do not believe ASU 2016-15 will have a material 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 did not have 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. The FASB recently clarified that only new or modified leases subsequent to adoption of ASU 2016-02 will require different accounting for "non-lease" components under the guidance in ASU 2014-09. 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 will impact the accounting and disclosure requirements for the ground leases, and other operating leases, where we are the lessee.


ASU 2016-02 will be effective for us under 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 but have tentatively concluded that we will apply the practical expedients.


Revenue Recognition
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). ASU 2014-09 is a comprehensive revenue recognition standard that will supersede nearly all existing GAAP revenue recognition guidance as well as impact the existing GAAP guidance governing the sale of 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 make 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 treatment of these transactions being presentation in the statement of operations (revenue and expense is reported when the sale is to a customer and net gain or loss is reported when the sale is to a non-customer). Based on the nature of our business, we believehave concluded that our property sales represent transactions with non-customers.
In February 2017, the FASB issued ASU 2017-05, Other Income: Gains and Losses from the Derecognition of NonfinancialNon-financial Assets (“ASU 2017-05”). ASU 2017-05 provides guidance on how entities recognize sales, including partial sales, of nonfinancialnon-financial assets (and in-substance nonfinancialnon-financial assets) to noncustomers.non-customers. ASU 2017-05 requires the seller to recognize a full gain or loss in a partial sale of nonfinancialnon-financial 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 ASU 2017-05 will be effective for public entities for annual and interim reporting periods beginning after December 15, 2017 and early adoption is permitted in periods ending after December 15, 2016. 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, the pattern of recognition for sales of real estate 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 expect ASU 2017-05 to significantly impact the recognition of property and land sales.
3.    Reclassifications
Certain amounts in the accompanying consolidated financial statements for 2016, including the change in presentation for the medical office properties determined to be discontinued operations (see Note 10) and the tax payments on stock-based compensation awards pursuant to ASU 2016-09, have been reclassified to conform to the 2017 consolidated financial statement presentation.
4.    Variable Interest Entities
Partnership
Due to the fact that the Limited Partners do not have kick out rights, or substantive participating rights, the Partnership is a variable interest entity ("VIE"). Because the General Partner holds majority ownership and exercises control over every aspect of the Partnership's operations, the General Partner has been determined as the primary beneficiary and, therefore, consolidates the Partnership.


The assets and liabilities of the General Partner and the Partnership are substantially the same, as the General Partner does not have any significant assets other than its investment in the Partnership. All of the Company's debt is an obligation of the Partnership.


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 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 JuneSeptember 30, 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 $66.7$77.6 million at JuneSeptember 30, 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 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 1120 properties during the sixnine months ended JuneSeptember 30, 2017. We determined that the 11these 20 properties acquired during the six months ended June 30, 2017 did not meet the revised definition of a business as the result of adopting ASU 2017-01 and, accordingly, we accounted for them as asset acquisitions as opposed to business combinations.


The following table summarizes amounts recognized for each major class of assets (in thousands) for these acquisitions during the sixnine months ended JuneSeptember 30, 2017:
Real estate assets$595,127
Lease related intangible assets32,079
Total acquired assets627,206
Below market lease liability1,224
Fair value of acquired net assets$625,982
Real estate assets$228,516
Lease related intangible assets11,178
Fair value of acquired net assets$239,694

The leases in the acquired properties had a weighted average remaining life at acquisition of approximately 6.97.7 years.
Fair Value Measurements
     
We determine the fair value of the individual components of real estate asset acquisitions primarily through calculating the "as-if vacant" value of a building, using an income approach, which 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 used in calculating the "as-if vacant" value for acquisition activity during the sixnine months ended JuneSeptember 30, 2017 are as follows:
 LowHigh
Exit capitalization rate4.10%5.32%
Net rental rate per square foot$3.50$10.00

 LowHigh
Discount rate5.81%6.82%
Exit capitalization rate4.31%5.32%
Lease-up period (months)912
Net rental rate per square foot - Industrial$3.50$5.70
An acquisition during the three months ended September 30, 2017 is located in a high performing industrial market in Northern New Jersey which is at the high end of our range of assumptions for net rental rate per square foot.
Capitalized acquisition costs were insignificant and the fair value of the 1120 properties acquired during the sixnine months ended JuneSeptember 30, 2017 was substantially the same as the cost of acquisition.



Dispositions
Dispositions of buildings (see Note 10 for the number of buildings sold as well as for their classification between continuing and discontinued operations) and undeveloped land generated net cash proceeds of $1.98$2.28 billion and $174.9$369.1 million during the sixnine months ended JuneSeptember 30, 2017 and 2016, respectively.



Dispositions for the sixnine months ended JuneSeptember 30, 2017 included 7784 consolidated properties sold as part of the Medical Office Portfolio Disposition to a subsidiary of Healthcare Trust of America, Inc. ("HTA"), as well as certain other buyers, for a total sales price of $2.35$2.60 billion and a gain on sale of $1.14$1.26 billion. Seven of these consolidated properties were sold during the three months ended September 30, 2017, for a total sales price of $250.0 million and a gain on sale of $120.4 million. The Medical Office Portfolio Disposition was executed in connection with our strategy to focus solely on the industrial real estate product type.


A portion of the sale price for the Medical Office Portfolio Disposition was financed through either unsecured notes, or first mortgage interests in a portion of the sold properties, that we provided to HTA and other buyers, totaling $400.0 million, which is reflected within notes receivable from property sales in the Consolidated Balance Sheets. These instruments mature at various points over the next three yearsthrough January 2020 and all bear interest rates at 4.0%. We concluded that the value, and the rate of interest, for these financial instruments would approximate fair value as computed using an income approach and that this determination of fair value was primarily based upon level 3 inputs. We have reviewed the creditworthiness of the borrowers and have concluded it is probable that we will collect all amounts due according to their contractual terms.


In connection with the Medical Office Portfolio Disposition, during the sixnine months ended JuneSeptember 30, 2017 we received $105.3 million for the sale of our interest in two unconsolidated joint ventures whose underlying assets were comprised of medical office properties, which is reflected within Capital Distributions from Unconsolidated Companies within the Consolidated Statements of Cash Flows. We recorded $47.5 million of income related to the sale of our interests in these unconsolidated joint ventures within equity in earnings of unconsolidated companies in the Consolidated Statements of Operations and Comprehensive Income. In connection with the sale of our interest in one of these unconsolidated joint ventures, we also recorded promote income (additional incentive-based cash distributions from the joint venture, in excess of our ownership interest) of $20.0 million from the sale of our share interest, which is reflected as a separate line item in the Consolidated Statements of Operations and Comprehensive Income and reflected within net cash provided by operating activities within the Consolidated Statements of Cash Flows. In connection with the sale, we recorded income tax expense totaling $19.7$19.1 million including $11.6$10.7 million classified within discontinued operations and $8.0$8.4 million classified within continuing operations in the Consolidated Statements of Operations and Comprehensive Income.

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 3.20% to 3.70%, depending on the attributes of the

specific loans. The current market rates we utilized were internally estimated; therefore, we have concluded that our determination of fair value for our fixed rate secured debt was primarily based upon level 3 inputs.


During the sixnine months ended JuneSeptember 30, 2017, we repaid threeseven fixed rate secured loans, totaling $42.9$66.3 million, which had a weighted average stated interest rate of 5.88%5.85%.


Unsecured Debt


At JuneSeptember 30, 2017, all of our unsecured debt bore interest at fixed rates and primarily consisted of unsecured notes that are publicly traded. We utilized broker estimates in estimating the fair value of our fixed rate unsecured debt. Our unsecured notes are thinly traded and, in certain cases, the broker estimates were not based upon comparable transactions. The broker estimates took into account any recent trades within the same series of our fixed rate unsecured debt, comparisons to recent trades of other series of our fixed rate unsecured debt, trades of fixed rate unsecured debt from companies with profiles similar to ours, as well as overall economic conditions. We reviewed these broker estimates for reasonableness and accuracy, considering whether the estimates were based upon market participant assumptions within the principal and most advantageous market and whether any other observable inputs would be more accurate indicators of fair value than the broker estimates. We concluded that the broker estimates were representative of fair value. We have determined that our estimation of the fair value of our fixed rate unsecured debt was primarily based upon level 3 inputs. The estimated trading values of our fixed rate unsecured debt, depending on the maturity and coupon rates, ranged from 98.00%99.00% to 128.00%130.00% of face value.
The indentures (and related supplemental indentures) governing our outstanding series of unsecured notes also require us to comply with financial ratios and other covenants regarding our operations. We were in compliance with all such financial covenants at JuneSeptember 30, 2017.


During the nine months ended September 30, 2017, we repaid the following unsecured loans:

In June 2017, we repaid our $250.0 million variable rate term loan, which had a scheduled maturity date of January 2019 and bore interest at LIBOR plus 1.00%, and recognized a loss of $523,000 from the write-off of unamortized deferred financing costs.
In June 2017, we repaid our $250.0 million variable rate term loan, which had a scheduled maturity date of January 2019 and bore interest at LIBOR plus 1.00%, and recognized a loss of $523,000 from the write-off of unamortized deferred financing costs. We also repaid $285.6 million of senior unsecured notes that had a stated interest rate of 6.50% and an effective interest rate of 6.08%, which hadwith a scheduled maturity indate of January 2018, and2018. We recognized a loss of $9.0 million including thea repayment premium and the write-off of unamortized deferred financing costs.

In July 2017, we repaid $128.7 million of senior unsecured notes that had both a stated and an effective interest rate of 6.75% with a scheduled maturity date of March 2020. We recognized a loss of $16.6 million including a repayment premium and the write-off of unamortized deferred financing costs.

Unsecured Line of Credit

The Partnership's unsecured line of credit hashad an interest rate on borrowings of LIBOR plus 0.93% (equal to 2.17% for outstanding borrowings at September 30, 2017), and had a maturity date of January 1, 2019, 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.in October 2017 was restated and amended (see Note 11). 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 JuneSeptember 30, 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.

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 net income attributable to common shareholders and the noncontrolling interest in earnings allocable to Limited Partner Units (to the extent the Limited Partner Units are dilutive), less dividends or distributions on participating securities that are anti-dilutive, by the sum of the weighted average number of common shares outstanding and, to the extent they are dilutive, weighted average number of Limited Partner Units outstanding and any potential dilutive securities for the period. Diluted net income per Common Unit is computed by dividing the net income attributable to common unitholders, less dividends or distributions on participating securities that are anti-dilutive, by the sum of the weighted average

number of Common Units outstanding and any potential dilutive securities for the period. The following table reconciles the components of basic and diluted net income per common share or Common Unit (in thousands):

9.    Segment Reporting
Reportable Segments
During the threenine months ended JuneSeptember 30, 2017, we substantially completed the Medical Office Portfolio Disposition, which resulted in all of our in-service medical office properties being classified within discontinued operations with the exception of a property that did not meet the criteria for classification as held for sale at JuneSeptember 30, 2017 (see Note 10). As a result of this transaction, our medical office properties are no longer presented as a separate reportable segment at JuneSeptember 30, 2017, with substantially all current and prior period operating results being classified within discontinued operations. The remaining medical office property included in continuing operations no longer meets the quantitative thresholds for separate presentation, and is classified as part of our non-reportable Rental Operations. Properties that are not included in our reportable segments, because they do not by themselves meet the quantitative thresholds for separate presentation as a reportable segment, are generally referred to as non-reportable Rental Operations. Our non-reportable Rental Operations primarily include our remaining office properties and medical office property at JuneSeptember 30, 2017.


As of JuneSeptember 30, 2017, after consideration of the Medical Office Portfolio Disposition, we had two reportable operating segments, the first consisting of the ownership and rental of industrial real estate investments. All of our industrial properties across the markets in which we operate are aggregated into one reportable segment as they

have similar economic characteristics and we provide similar leasing arrangements and services to similar types of, and in many cases, the same tenants. The operations of our industrial properties, as well as our non-reportable Rental Operations, are collectively referred to as "Rental Operations." Our second reportable segment consists of various real estate services such as property management, asset management, maintenance, leasing, development, general contracting and construction management to third-party property owners and joint ventures, and is collectively referred to as "Service Operations." Our reportable segments 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.

Discontinued Operations
All of the properties included in discontinued operations are medical office properties. Because of the size of the Medical Office Portfolio Disposition, and the fact that it represented our exit from the medical office product type, we determined that the disposition represented a strategic shift that would have a major effect on our operations and financial results. As such, the consolidated in-service properties in this portfolio met the criteria to be classified within discontinued operations. As the result of its classification within discontinued operations, the in-service assets and liabilities of this portfolio are required to be presented as held for sale for all prior periods presented in our Consolidated Balance Sheets. Operating results pertaining to the properties classified within discontinued operations were reclassified to discontinued operations for all prior periods presented in our Consolidated Statements of Operations and Comprehensive Income.
The following table illustrates the number of sold or held-for-sale properties included in, or excluded from, discontinued operations in this report:

Properties excluded from discontinued operations2 12 32 46
Total properties sold or classified as held-for-sale10 85 32 127

    
Properties sold in 2017 but excluded from discontinued operations included four properties under development, which were disposed as part of the Medical Office Portfolio Disposition, as these properties did not meet the criteria to be included in discontinued operations.
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 was based upon an allocable share of our consolidated unsecured interest expense, as none of the properties included in discontinued operations were encumbered by secured debt. 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.

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;

Business Overview
The General Partner and Partnership collectively specialize in the ownership, management and development of industrial 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 2016 Annual Report.
At JuneSeptember 30, 2017, we:
Owned or jointly controlled 498501 primarily industrial properties, of which 472480 properties with 129.5135.3 million square feet were in service and 2621 properties with 10.911.1 million square feet were under development. The 472480 in-service properties were comprised of 432439 consolidated properties with 118.7124.4 million square feet and 4041 jointly controlled unconsolidated properties with 10.811.0 million square feet. The 2621 properties under development consisted of 2216 consolidated properties with 9.88.8 million square feet and fourfive jointly controlled unconsolidated properties with 1.12.3 million square feet.
Owned directly, or through ownership interests in unconsolidated joint ventures (with acreage not adjusted for our percentage ownership interest), approximately 2,1001,900 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.


During the threenine months ended JuneSeptember 30, 2017, we substantially completed the Medical Office Portfolio Disposition, which resulted in all of our in-service medical office properties being classified within discontinued operations with the exception of a property that did not meet the criteria for classification as held for sale at JuneSeptember 30, 2017. As a result of this transaction, our medical office properties are no longer presented as a separate reportable segment at JuneSeptember 30, 2017, as they no longer meet the quantitative thresholds for separate presentation and, to the extent not classified within discontinued operations, are classified as part of our non-reportable Rental Operations. Properties that are not included in our reportable segments, because they do not by themselves meet the quantitative thresholds for separate presentation as a reportable segment, are generally referred to as non-reportable Rental Operations. Our non-reportable Rental Operations primarily include our remaining office properties and medical office property at JuneSeptember 30, 2017.


As of JuneSeptember 30, 2017, we had two reportable operating segments, the first consisting of the ownership and rental of industrial real estate investments. The operations of our industrial properties, as well as our non-reportable Rental Operations, are collectively referred to as "Rental Operations." Our second reportable segment consists of various real estate services such as property management, asset management, maintenance, leasing, development, general contracting and construction management to third-party property owners and joint ventures, and is collectively referred to as "Service Operations." Our reportable segments offer different product 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 JuneSeptember 30, 2017 and 2016, respectively:

This amount excludes additional amounts paid by tenants as reimbursement for operating expenses.
The decreased occupancy within our industrial portfolio at September 30, 2017, compared to September 30, 2016, resulted from speculative developments being placed in service or acquired from third parties.

Total Leasing Activity


The initial leasing of development projects or vacant space in acquired properties is referred to as first generation lease activity. Our ability to maintain and improve occupancy rates and net effective rents primarily depends upon our continuing ability to re-lease expiring space. The leasing of such space that we have previously held under lease is referred to as second generation lease activity. The total leasing activity for our consolidated and unconsolidated rental properties included within both continuing and discontinued operations, expressed in square feet of leases signed, is as follows (in thousands):

* 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 1120 buildings during the sixnine months ended JuneSeptember 30, 2017, one of which was sold as part of the Medical Office Portfolio Disposition, and 17 buildings during the year ended December 31, 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):

* Includes fair value of real estate assets and net acquired lease-related intangible assets, including above or below market leases, but excludes other acquired working capital assets and liabilities.** In-place yields of completed acquisitions are calculated as the current annualized net rental payments from space leased to tenants at the date of acquisition, divided by the acquisition price of the acquired real estate. Annualized net rental payments are comprised of base rental payments, excluding additional amounts payable by tenants as reimbursement for operating expenses, less current annualized operating expenses not recovered through tenant reimbursements.*** Represents percentage of total square feet leased based on executed leases and without regard to whether the leases have commenced, at the date of acquisition.
Building Dispositions
We regularly work to identify, consider and pursue opportunities to dispose of properties on an opportunistic basis and on a basis that is generally consistent with our strategic plans.
We sold8595 consolidated properties during the sixnine months ended JuneSeptember 30, 2017, including 7784 properties sold as part of the Medical Office Portfolio Disposition, and 32 wholly owned buildings during the year ended December 31, 2016.

* In-place yields of completed dispositions are calculated as annualized net operating income from space leased to tenants at the date of sale on a lease-up basis, including full rent from all executed leases, even if currently in a free rent period, divided by the sales price. Annualized net operating income is comprised of base rental payments, excluding reimbursement of operating expenses, less current annualized operating expenses not recovered through tenant reimbursements.** Represents percentage of total square feet leased based on executed leases and without regard to whether the leases have commenced, at the date of sale.
Development
At JuneSeptember 30, 2017, we had 10.911.1 million square feet of property under development with total estimated costs upon completion of $802.9$751.4 million compared to 6.07.2 million square feet with total estimated costs upon completion of $553.9$588.8 million at JuneSeptember 30, 2016. The square footage and estimated costs include both consolidated properties and unconsolidated joint venture development activity at 100%.

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 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):

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 9 to the consolidated financial statements included in Part I, Item 1 of this Report shows a calculation of our PNOI for the sixnine months ended JuneSeptember 30, 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 and sixnine months ended JuneSeptember 30, 2017, as those properties that were owned and in-service as of January 1, 2016, and held as in-service properties through the end of the reporting periods shown. In addition to excluding properties that were sold or identified as held-for-sale through the end of the reporting periods shown, we also exclude properties where revenues from lease buyouts in excess of $250,000 have been recognized in either the full calendar year 2016 or year-to-date calendar year 2017. A reconciliation of income from continuing operations before income taxes to SPNOI is presented as follows (in thousands, except percentage data):

(3) Represents the average annualized contractual rent per square foot for the six months ended June 30, 2017 and 2016 for tenants in occupancy in properties in the same property population. Cash rent does not include the tenant's obligation to pay property operating expenses and real estate taxes. If a tenant was within a free rent period at June 30, 2017 or 2016 its rent would equal zero for purposes of this metric.

$174,233
 $207,228
The following factors contributed to the increase in rental and related revenue from continuing and discontinued operations:
We acquired 2635 properties and placed 2231 developments in service from January 1, 2016 to JuneSeptember 30, 2017, which provided incremental revenues from continuing operations of $15.1$15.8 million during the three months ended JuneSeptember 30, 2017, as compared to the same period in 2016.
Increased occupancy and rental rates within our same-property portfolio also contributed to the increase to rental and related revenue from continuing operations. Average commencement occupancy and rental rates in our same-property portfolio both increased from the three months ended June 30, 2016.
The sale of 4043 in-service properties since January 1, 2016, which did not meet the criteria to be classified within discontinued operations, resulted in a decrease of $13.5$10.3 million to rental and related revenue from continuing operations in the three months ended JuneSeptember 30, 2017, as compared to the same period in 2016, which partially offset the aforementioned increases to rental and related revenues.revenue from continuing operations.
Rental and related revenue from discontinued operations for the three months ended JuneSeptember 30, 2017 decreased compared to the same period in 2016 as the properties sold and classified within discontinued operations were not held for the entire three-month period ended JuneSeptember 30, 2017, with a majority of the properties being sold in the first six months of 2017.
Rental Expenses and Real Estate Taxes
The following table sets forth rental expenses and real estate taxes from continuing operations by reportable segment, as well as total rental expenses and real estate taxes from discontinued operations (in thousands):

Rental expenses from continuing operations decreased by $2.5 million$709,000 during the three months ended JuneSeptember 30, 2017, compared to the same period in 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, which did not meet the criteria to be classified within discontinued operations. The decrease was partially offset by acquisitions and developments placed in service from January 1, 2016 to JuneSeptember 30, 2017.


Real estate tax expense from continuing operations increased by $2.0$2.2 million during the three months ended JuneSeptember 30, 2017, compared to the same period in 2016. The increase to real estate tax expense was mainly the result of acquisitions and developments placed in service from January 1, 2016 to JuneSeptember 30, 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.

The decreases in both rental expenses and real estate tax expense from discontinued operations are a result of the timing of the sales of properties classified within discontinued operations, with a majority of these properties being sold in the first six months of 2017.
Service Operations
The following table sets forth the components of net earnings from the Service Operations reportable segment (in thousands):

 $2,169


General contractor and service fee revenues, and netNet earnings from Service Operations decreased during the three months ended JuneSeptember 30, 2017 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 from continuing operations increased from $61.1$61.8 million for the three months ended JuneSeptember 30, 2016 to $67.0$68.0 million for the same period in 2017 primarily as the result of the properties acquired and the developments placed in service since January 1, 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 of Unconsolidated Companies
Equity in earnings from unconsolidated companies represents our ownership share of net income from investments in unconsolidated companies that generally own and operate rental properties. Equity in earnings increased from $3.5unconsolidated companies decreased from $12.0 million for the three months ended JuneSeptember 30, 2016 to $51.9$1.8 million for the same period in 2017. During the three months ended JuneSeptember 30, 2017,2016, we recorded $48.9$8.7 million to equity in earnings primarily asfrom unconsolidated companies related to our share of the result of gains on the sale of our interests in three unconsolidated joint ventures, two of which were sold as part of the Medical Office Portfolio Disposition.
Gain on Dissolution of Unconsolidated Company
We recognized a $30.7 million gain related to the dissolution of an unconsolidated joint venture during the three months ended June 30, 2016. We did not experience any such dissolutions during the three months ended June 30, 2017.
Promote Income
We recognized $20.0 million of promote income from the sale of our interest in one of our unconsolidated joint ventures, as part of the Medical Office Portfolio Disposition, during the three months ended June 30, 2017 compared to $24.1 million of promote income related to the dissolution of an unconsolidated joint venture during the three months ended June 30, 2016.buildings and undeveloped land.
Gain on Sale of Properties - Continuing Operations


The $34.3$22.0 million recognized as gain on sale of properties in continuing operations for the three months ended JuneSeptember 30, 2017 is the result of the sale of fivethree properties that did not meet the criteria for inclusion in discontinued operations.
        
The $39.3$82.7 million recognized as gain on sale of properties in continuing operations for the three months ended JuneSeptember 30, 2016 was the result of the gain from the sale of six13 properties that 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 increaseddecreased from $11.6$12.5 million for the three months ended JuneSeptember 30, 2016 to $11.9$10.1 million for the same period in 2017. The following table sets forth the factors that led to the increaseddecreased general

and administrative expenses (in millions):
General and administrative expenses - three-month period ended June 30, 2016$11.6
 Increase to overall pool of overhead costs1.5
 Increased absorption of costs by wholly owned leasing and development activities (1)(3.9)
 Decreased allocation of costs to Service Operations and Rental Operations (2)2.7
General and administrative expenses - three-month period ended June 30, 2017$11.9
General and administrative expenses - three-month period ended September 30, 2016$12.5
 Decrease to overall pool of overhead costs(4.9)
 Increased absorption of costs by wholly owned leasing and development activities (1)(0.4)
 Decreased allocation of costs to Service Operations and Rental Operations (2)2.9
General and administrative expenses - three-month period ended September 30, 2017$10.1
(1) We capitalized $5.0$4.3 million and $9.9$8.1 million of our total overhead costs to leasing and development, respectively, for consolidated properties during the three months ended JuneSeptember 30, 2017, compared to capitalizing $6.0$4.0 million and $5.0$8.1 million of such costs, respectively, for the three months ended JuneSeptember 30, 2016. Combined overhead costs capitalized to

leasing and development totaled 41.6%40.2% and 32.1%33.7% of our overall pool of overhead costs for the three months ended JuneSeptember 30, 2017 and 2016, respectively.
(2) The decrease in allocation of costs to Service Operations and Rental Operations resulted from a lower volume of third-party construction projects during the three months ended JuneSeptember 30, 2017 as well as a lower allocation of property management and maintenance expenses to Rental Operations due to significantly increasing our focus on industrial properties which are less management intensive.


Interest Expense
Interest expense allocable to continuing operations decreased from $29.5$27.3 million for the three months ended JuneSeptember 30, 2016 to $21.7$20.8 million for the three months ended JuneSeptember 30, 2017. The decrease to interest expense from continuing operations was primarily due to interest savings from reducing leverage by $1.10$1.07 billion and refinancing higher rate indebtedness since March 31,June 30, 2016.
We capitalized $5.3$5.0 million and $3.8$3.5 million of interest costs for the three months ended JuneSeptember 30, 2017 and 2016, respectively.
Debt Extinguishment
During the three months ended JuneSeptember 30, 2017, we repaid our $250.0 million variable rate term loan that had a maturity date of January 2019 and bore interest at LIBOR plus 1.00%, and recognized a loss of $523,000 from the write-off of unamortized deferred financing costs. We also repaid $285.6$128.7 million of senior unsecured notes that had both a stated interest rate of 6.50% and an effective interest rate of 6.08%6.75%, which hadwith a scheduled maturity in January 2018,March 2020, and recognized a loss of $9.0$16.6 million including thea repayment premiumspremium and the write-off of unamortized deferred financing costs.
 
During the three months ended JuneSeptember 30, 2016, we repurchased $72.0redeemed the remaining $203.0 million of our outstanding 5.95% senior unsecured notes, through a tender offer, prior to their maturity date in February 2017.notes. This repurchaseredemption resulted in a loss on debt extinguishment of $2.4$6.2 million, which consisted of repurchasea redemption premium 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.
We had 81 consolidated properties classified as discontinued operations for both the three months ended JuneSeptember 30, 2017 and JuneSeptember 30, 2016. These 81 consolidated properties consisted of 7380 medical office properties that were sold and eightone medical office propertiesproperty held for sale. As a result, we classified income before gain on sales, of $11.1$2.6 million and $2.3$4.2 million within discontinued operations for the three months ended JuneSeptember 30, 2017 and 2016, respectively. The increase to income before gain on sales for these properties was the result of lower depreciation expense in the three months ended June 30, 2017 compared to the same period in 2016, as the properties met the criteria for held-for-sale classification and accordingly ceased depreciation for a short period of time prior to their sale during the three months ended June 30, 2017. The gains on disposal of these properties, totaling $1.11 billion,

$120.2 million, and related income tax impact, totaling $11.6 million,$876,000, for the three months ended JuneSeptember 30, 2017 are also reported in discontinued operations, which are further discussed in Note 10 to the consolidated financial statements included in Part I, Item 1 of this Report.

 $609,906
The following factors contributed to the increase in rental and related revenue from continuing and discontinued operations:


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 $9.6$8.6 million in termination fees compared to the sixnine months ended JuneSeptember 30, 2016.


Increased expense reimbursements primarily due to increased real estate taxes in our existing properties during the nine months ended September 30, 2017, as compared to the same period in 2016, contributed to the increase to rental and related revenue from continuing operations.

Increased occupancy and rental rates within our same-property portfolio also contributed to the increase to rental and related revenue from continuing operations. Average commencement occupancy and rental rates in our same-property portfolio both increased from the sixnine months ended JuneSeptember 30, 2016.


We acquired 2635 properties and placed 2231 developments in service from January 1, 2016 to JuneSeptember 30, 2017, which provided incremental revenues from continuing operations of $28.1$44.0 million in the sixnine months ended JuneSeptember 30, 2017, as compared to the same period in 2016.


The sale of 4043 in-service properties, since January 1, 2016, which did not meet the criteria for inclusion within discontinued operations, resulted in a decrease of $28.1$30.0 million to rental and related revenue from continuing operations in the sixnine months ended JuneSeptember 30, 2017, as compared to the same period in 2016, which partially offset the aforementioned increases to rental and related revenues.revenue from continuing operations.


Rental and related revenue from discontinued operations for the sixnine months ended JuneSeptember 30, 2017 decreased compared to the same period in 2016 as the properties sold and classified within discontinued operations were not held for the entire six-monthnine-month period ended JuneSeptember 30, 2017, with a majority of the properties being sold in the first six months of 2017.

Overall, rental expenses from continuing operations decreased by $7.0$7.7 million in the sixnine months endedJuneSeptember 30, 2017, compared to the same period in 2016. 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, which did not meet the criteria to be classified within discontinued operations. The decrease was partially offset by acquisitions and developments placed in service from January 1, 2016 to JuneSeptember 30, 2017.
Overall, real estate tax expense from continuing operations increased by $3.7$5.9 million in the sixnine months ended JuneSeptember 30, 2017, compared to the same period in 2016. The increase to real estate tax expense was mainly the result of acquisitions and developments placed in service from January 1, 2016 to JuneSeptember 30, 2017, and by increasedas well as increases in real estate taxes foron 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.
The decreases in both rental expenses and real estate tax expense from discontinued operations are a result of the timing of the sales of properties classified within discontinued operations, with a majority of these properties being sold in the first six months of 2017.
Service Operations
The following table sets forth the components of net earnings from the Service Operations reportable segment (in thousands):
Six Months Ended June 30,Nine Months Ended September 30,
2017 20162017 2016
Service Operations:      
General contractor and service fee revenue$32,975
 $49,195

Net earnings from Service Operations$2,977
 $6,047
$4,115
 $8,216


General contractor and service fee revenues, and net earnings from Service Operations, decreased during the sixnine months ended JuneSeptember 30, 2017 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 increased from $120.7$182.5 million during the sixnine months ended JuneSeptember 30, 2016 to $129.0$197.0 million for the same period in 2017, primarily as the result of the properties acquired and the developments placed in service since January 1, 2016. The impact of acquired properties and developments placed

in service was partially offset by asset dispositions that did not meet the criteria to be classified within discontinued operations.
Equity in Earnings of Unconsolidated Companies
Equity in earnings from unconsolidated companies increased from $25.4$37.4 million during the sixnine months ended JuneSeptember 30, 2016 to $56.7$58.5 million for the same period in 2017. During the sixnine months ended JuneSeptember 30, 2017, we recorded $50.7 million to equity in earnings

from unconsolidated companies primarily as the result of the gains on sale of our interests in three unconsolidated joint ventures, two of which were sold as part of the Medical Office Portfolio Disposition, and our share of the gain on the sale of one joint venture building. During the sixnine months ended JuneSeptember 30, 2016, we recorded $18.0$25.2 million to equity in earnings from unconsolidated companies for our share of the net gains on the sale of unconsolidated joint venture properties or for sales of our interest in unconsolidated joint ventures.
Gain on Dissolution of Unconsolidated Company
We recognized a $30.7 million gain related to the dissolution of an unconsolidated joint venture during the sixnine months ended JuneSeptember 30, 2016. We did not experience any similar dissolutions during the sixnine months ended JuneSeptember 30, 2017.
Promote Income
We recognized $20.0 million of promote income from the sale of our interest in one of our unconsolidated joint ventures, as part of the Medical Office Portfolio Disposition, during the sixnine months ended JuneSeptember 30, 2017 compared to $24.1$26.3 million of promote income related to the dissolution of an unconsolidated joint venture during the sixnine months ended JuneSeptember 30, 2016.
Gain on Sale of Properties - Continuing Operations
The $71.4$93.3 million recognized in continuing operations for the sixnine months ended JuneSeptember 30, 2017 is comprised primarily of the gains from the sale of 1215 properties. These properties did not meet the criteria for inclusion in discontinued operations.
The $54.9$137.6 million recognized in continuing operations for the sixnine months ended JuneSeptember 30, 2016 is primarily comprised of the gains from the sale of nine22 properties that did not meet the criteria for inclusion in discontinued operations.
Impairment ChargeCharges
Impairment charges classified in continuing operations include the impairment of undeveloped land and buildings. We recognized impairment charges of $859,000$3.6 million on one building for the six months ended June 30, 2017. We recognized impairment charges12 acres of land and $12.1 million on 174 acres of land, for the sixnine months ended JuneSeptember 30, 2016.2017 and 2016, respectively. These impairment charges were primarily 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 $859,000 and $3.0 million on buildings for the nine months ended September 30, 2017 and 2016, respectively.
General and Administrative Expense
General and administrative expenses increaseddecreased from $29.7$42.2 million for the sixnine months ended JuneSeptember 30, 2016 to $31.1$41.2 million for the same period in 2017. The following table sets forth the factors that led to the increaseddecreased general and administrative expenses (in millions):
General and administrative expenses - six months ended June 30, 2016$29.7
Increase to overall pool of overhead costs0.4
Increased absorption of costs by wholly owned leasing and development activities (1)(4.4)
Decreased allocation of costs to Service Operations and Rental Operations (2)5.4
General and administrative expenses - six months ended June 30, 2017$31.1
General and administrative expenses - nine months ended September 30, 2016$42.2
Decrease to overall pool of overhead costs(4.5)
Increased absorption of costs by wholly owned leasing and development activities (1)(4.7)
Decreased allocation of costs to Service Operations and Rental Operations (2)8.2
General and administrative expenses - nine months ended September 30, 2017$41.2

(1) We capitalized $10.2$14.6 million and $18.2$26.3 million of our total overhead costs to leasing and development, respectively, for consolidated properties during the sixnine months ended JuneSeptember 30, 2017, compared to capitalizing $12.8$16.7 million and $11.3$19.4 million of such costs, respectively, for the sixnine months ended JuneSeptember 30, 2016. Combined overhead costs capitalized to leasing and development totaled 37.2%38.1% and 31.7%32.3% of our overall pool of overhead costs for the sixnine months ended JuneSeptember 30, 2017 and 2016, respectively.
(2) The decrease in allocation of costs to Service Operations and Rental Operations resulted from a lower volume of third-party construction projects during the sixnine months ended JuneSeptember 30, 2017 as well as a lower allocation of property management and maintenance expenses to Rental Operations due to significantly increasing our focus on industrial properties, which are less management intensive.


Interest Expense
Interest expense allocable to continuing operations decreased from $59.6$87.3 million for the sixnine months ended JuneSeptember 30, 2016 to $44.6$65.4 million for the sixnine months ended JuneSeptember 30, 2017. The decrease to interest expense from continuing operations was primarily due to interest savings from reducing leverage by $1.10$1.19 billion and refinancing higher rate indebtedness since MarchDecember 31, 2016.2015.
We capitalized $9.5$14.5 million and $13.0 million of interest costs during both the sixnine months ended JuneSeptember 30, 2017 and JuneSeptember 30, 2016.2016, respectively.
Debt Extinguishment
During the sixnine months ended JuneSeptember 30, 2017, we repaid our $250.0 million variable rate term loan, thatwhich had a scheduled maturity date of January 2019 and bore interest at LIBOR plus 1.00%, and recognized a loss of $523,000 from the write-off of unamortized deferred financing costs.. We also repaid $285.6 million of senior unsecured notes that had a stated interest rate of 6.50% and an effective interest rate of 6.08%, which hadwith a scheduled maturity indate of January 2018 and $128.7 million of senior unsecured notes with a scheduled maturity date of March 2020. We recognized a total loss on debt extinguishment of $9.0$26.1 million includingfrom these transactions during the nine months ended September 30, 2017, which included repayment premiumpremiums and the write-off of unamortized deferred financing costs.
During the sixnine months ended JuneSeptember 30, 2016, we repurchased $72.0 million of our outstanding 5.95% Senior Unsecured Notes,senior unsecured notes, through a tender offer, prior to their maturity date in February 2017. We recognized2017 and redeemed the remaining $203.0 million of our 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 $2.4$8.7 million during the sixnine months ended JuneSeptember 30, 2016, which included repurchase and redemption premiums prepayment premiums as well asand the write-off of unamortized deferred financing costs.
Discontinued Operations
The operations of 81 consolidated properties were classified as discontinued operations for both the sixnine months ended JuneSeptember 30, 2017 and JuneSeptember 30, 2016. These 81 consolidated properties consisted of 7380 medical office properties that were sold and eightone medical office propertiesproperty held for sale. As a result, we classified income before gain on sales, of $15.2$17.7 million and $4.5$9.1 million within discontinued operations for the sixnine months ended JuneSeptember 30, 2017 and 2016, respectively. The increase to income before gain on sales for these properties was the result of lower depreciation expense in the sixnine months ended JuneSeptember 30, 2017 compared to the same period in 2016, as the properties met the criteria for held-for-sale classification and accordingly ceased depreciation for a short period of time prior to their sale during the threenine months ended JuneSeptember 30, 2017. The gains on disposal of these properties, totaling $1.11$1.23 billion, and related income tax impact, totaling $11.6$10.7 million, for the sixnine months ended JuneSeptember 30, 2017 are also reported in discontinued operations, which are further discussed in Note 10 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. We had no$5.0 million of outstanding borrowings on the Partnership's $1.20 billion

unsecured line of credit, had $76.3$27.3 million of cash on hand and held $839.1$512.5 million of restricted cash for future like kind exchange transactions at JuneSeptember 30, 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 and through accessing the public debt and equity markets. At JuneSeptember 30, 2017, we also held $400.0 million of notes receivable from the buyers of our medical office properties that will be repaidare scheduled to mature at various points over a three-year period.through January 2020.



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.


We 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.


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 JuneSeptember 30, 2017.


At JuneSeptember 30, 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 (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 has an at the market ("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 sixnine months ended JuneSeptember 30, 2017, the General Partner did not issue any common shares pursuant to its ATM equity program. As of JuneSeptember 30, 2017, the ATM equity program still had $108.1 million worth of new common shares available to issue.


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.
Sales of land and depreciable properties provided $1.98$2.28 billion in net proceeds during the sixnine months ended JuneSeptember 30, 2017. We also hold $70.0 million of notes guaranteed by a buyer with an A+ rated health system and $330.0 million of first mortgages that we provided for certain of the properties in the Medical Office Portfolio, and which are expected to mature in various tranches over the next three years with the last maturity date in January 2020.
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 sixnine months ended JuneSeptember 30, 2017, our share of sale and capital distributions from unconsolidated joint ventures totaled $111.6 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. 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 $10.2$14.6 million and $12.8$16.7 million of overhead costs related to leasing activities, including both first and second generation leases, during the sixnine months ended JuneSeptember 30, 2017 and 2016, respectively. We capitalized $18.2$26.3 million

and $11.3$19.4 million of overhead costs related to development activities, including both development and tenant improvement projects on first and second generation space, during the sixnine months ended JuneSeptember 30, 2017 and 2016, respectively. Combined overhead costs capitalized to leasing and development totaled 37.2%38.1% and 31.7%32.3% of our overall pool of overhead costs for the sixnine months ended JuneSeptember 30, 2017 and 2016, respectively. Further discussion of the capitalization of overhead costs can be found herein, in the quarter-to-quarter comparison of general and administrative expenses of this 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 2016 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 $9.5$14.5 million and $13.0 million of interest costs during both the sixnine months ended JuneSeptember 30, 2017 and 2016.2016, respectively.
The following table summarizes our second generation capital expenditures by reportable operating segment (in thousands):

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 $0.19 per common share or Common Unit in the first, second and secondthird quarters of 2017, and the General Partner's board of directors declared dividends or distributions of $0.19$0.20 per common share or Common Unit for the thirdfourth quarter of 2017.
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 are subject to actual cash available for distribution, our financial condition, capital requirements and such other factors as the General Partner's board of directors deems relevant.


Debt Maturities
Debt outstanding at JuneSeptember 30, 2017 had a face value totaling $2.30$2.15 billion with a weighted average interest rate of 4.61%4.46% and maturities at various dates through 2028. Of this total amount, we had $1.96$1.83 billion of unsecured debt, $338.3$313.2 million of secured debt and no$5.0 million of outstanding borrowings on our unsecured line of credit at JuneSeptember 30, 2017. Scheduled principal amortization, maturities and early repayments of such debt totaled $631.0$780.3 million for the sixnine months ended JuneSeptember 30, 2017.

In July 2017, we redeemed $128.7 million
The Partnership’s unsecured line of 6.75% senior unsecured notes due March 2020.

credit is reflected in the table above as maturing in January 2023, based on the ability to exercise the two six-month extension options from its amended stated maturity date of January 2022 (see Note 11). 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.


Repayments of Outstanding Debt


In June 2017, we repaid our $250.0 million variable rate term loan, thatwhich had a scheduled maturity date of January 2019 and bore interest at LIBOR plus 1.00%., and recognized a loss of $523,000 from the write-off of unamortized deferred financing costs. We also repaid $285.6 million of senior unsecured notes that had a stated interest rate of 6.50% and an effective interest rate of 6.08%, prior to theirwith a scheduled maturity date inof January 2018.2018, and recognized a loss of $9.0 million, including a repayment premium and the write-off of unamortized deferred financing costs.


In July 2017, we repaid $128.7 million of senior unsecured notes that had both a stated and an effective interest rate of 6.75% with a scheduled maturity date of March 2020. We recognized a loss of $16.6 million, including a repayment premium and the write-off of unamortized deferred financing costs.

To the extent that it supports our overall capital strategy, we may purchase or redeem some of our outstanding unsecured notes prior to their stated maturities.


Contractual Obligations


Aside from repayments of long-term debt described above, our outstanding ground lease obligation has significantly decreased due to the Medical Office Portfolio Disposition as all our ground leases were held within the medical

office segment. There are no other material changes in our outstanding commitments since December 31, 2016, as previously discussed in our 2016 Annual Report.
Historical Cash Flows
Cash and cash equivalents were $76.3$27.3 million and $91.7$110.2 million at JuneSeptember 30, 2017 and 2016, respectively. The following table highlights significant changes in net cash associated with our operating, investing and financing activities (in millions):

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 sixnine months ended JuneSeptember 30, 2016, was due to improved operational performance and lower cash paid for interest, as the result of the significant debt repayments or refinancings that took place throughout 2016 and 2017.2017, partially offset by the impact of the Medical Office Portfolio Disposition.


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 sixnine months ended JuneSeptember 30, 2017, we paid cash of $237.5$620.9 million and $67.9$127.7 million, respectively, for real estate and undeveloped land acquisitions, compared to $16.0 million and $27.2$77.6 million for real estate and undeveloped land acquisitions in the same period in 2016.
Real estate development costs were $288.8$421.7 million during the sixnine months ended JuneSeptember 30, 2017, compared to $213.3$308.2 million for the same period in 2016.
Sales of land and depreciated properties provided $1.98$2.28 billion in net proceeds for the sixnine months ended JuneSeptember 30, 2017, compared to $174.9$369.1 million for the same period in 2016.
The increased cash outflows reflected in the Other Assets line of the Consolidated Statements of Cash Flows for the sixnine months ended JuneSeptember 30, 2017 was the result of a portion of the proceeds from the Medical Office Portfolio Disposition being transferred into escrow for use in future like kind exchange transactions, and not meeting the criteria for classification as cash and equivalents. The cash outflows from such transfers totaled $798.6$472.4 million during the sixnine months ended JuneSeptember 30, 2017, compared to $17.7$37.4 million during the sixnine months ended JuneSeptember 30, 2016. During the nine months ended September 30, 2016, we also received a full repayment of a $200.0 million seller-financed mortgage from the buyers of an office portfolio that we sold in April 2015.

Second generation tenant improvements, leasing costs and building improvements totaled $20.1$34.4 million for the sixnine months ended JuneSeptember 30, 2017 compared to $30.2$39.2 million for the same period in 2016.
For the sixnine months ended JuneSeptember 30, 2017, we received $111.6 million in capital distributions from unconsolidated joint ventures, primarily related to selling our interests in two joint ventures in connection with the Medical Office Portfolio Disposition, compared to $36.3$52.5 million during the same period in 2016.
For the sixnine months ended JuneSeptember 30, 2017, we made capital contributions of $2.0$6.3 million to unconsolidated joint ventures, compared to $51.0$54.9 million during the same period in 2016.



Financing Activities
The following items highlight significant capital transactions:
During the sixnine months ended JuneSeptember 30, 2016, the General Partner issued 4.28.3 million common shares pursuant to its ATM equity program, for net proceeds of approximately $98.5$213.6 million. The General Partner did not issue any shares under its ATM equity program during the sixnine months ended JuneSeptember 30, 2017.
In JuneDuring the nine months ended September 30, 2016, the Partnership issued $375.0 million of senior unsecured notes that bear interest at a stated rate of 3.25%, have an effective rate of 3.36%, and mature on June 30, 2026. A portionThe Partnership did not issue any senior unsecured notes during the nine months ended September 30, 2017.

We paid regular cash dividends or distributions totaling $135.1 million and $124.7 million for the six months ended June 30, 2017 and 2016, respectively.


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 limited partners (or similar owning entities) that lack substantive participating or kick out rights and (iii) establish whether or not activities within the venture are on behalf of an investor with disproportionately few voting rights in making this VIE determination. To the extent that we (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 JuneSeptember 30, 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 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 joint ventures represented approximately 2% and 3% of our total assets at JuneSeptember 30, 2017 and December 31, 2016, respectively. Total assets of our unconsolidated joint ventures were $539.7$568.1 million and $743.4 million at JuneSeptember 30, 2017 and December 31, 2016, respectively. The combined revenues of our unconsolidated joint ventures totaled $42.8$57.0 million and $70.8$97.5 million for the sixnine months ended JuneSeptember 30, 2017 and 2016, respectively.
We have guaranteed the repayment of certain secured and unsecured loans of our unconsolidated joint ventures. The outstanding balances on the guaranteed portion of these loans totaled $66.7$77.6 million at JuneSeptember 30, 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.
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.

As the above table incorporates only those exposures that existed at JuneSeptember 30, 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 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.
