EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended June 30, 2016 of Brandywine Realty Trust (the “Parent Company”) and Brandywine Operating Partnership L.P. (the “Operating Partnership”). The Parent Company is a Maryland real estate investment trust, or REIT, that owns its assets and conducts its operations through the Operating Partnership, a Delaware limited partnership, and subsidiaries of the Operating Partnership. The Parent Company, the Operating Partnership and their consolidated subsidiaries are collectively referred to in this report as the “Company”. In addition, as used in this report, terms such as “we”, “us”, and “our” may refer to the Company, the Parent Company, or the Operating Partnership.

The Parent Company is the sole general partner of the Operating Partnership and, as of June 30, 2016, owned a 99.1% interest in the Operating Partnership. The remaining 0.9% interest consists of common units of limited partnership interest issued by the Operating Partnership to third parties in exchange for contributions of properties to the Operating Partnership. As the sole general partner of the Operating Partnership, the Parent Company has full and complete authority over the Operating Partnership’s day-to-day operations and management.

Management operates the Parent Company and the Operating Partnership as one enterprise. The management of the Parent Company consists of the same members as the management of the Operating Partnership.

As general partner with control of the Operating Partnership, the Parent Company consolidates the Operating Partnership for financial reporting purposes, and the Parent Company does not have significant assets other than its investment in the Operating Partnership. Therefore, the assets and liabilities of the Parent Company and the Operating Partnership are the same on their respective financial statements. The separate discussions of the Parent Company and the Operating Partnership in this report should be read in conjunction with each other to understand the results of the Company's operations on a consolidated basis and how management operates the Company.

The Company believes that combining the quarterly reports on Form 10-Q of the Parent Company and the Operating Partnership into a single report will result in the following benefits:

| · | facilitate a better understanding by the investors of the Parent Company and the Operating Partnership by enabling them to view the business as a whole in the same manner as management views and operates the business;

| · | remove duplicative disclosures and provide a more straightforward presentation in light of the fact that a substantial portion of the disclosure applies to both the Parent Company and the Operating Partnership; and

| · | create time and cost efficiencies through the preparation of one combined report instead of two separate reports.

There are few differences between the Parent Company and the Operating Partnership, which are reflected in the footnote disclosures in this report. The Company believes it is important to understand the differences between the Parent Company and the Operating Partnership in the context of how these entities operate as an interrelated consolidated company. The Parent Company is a REIT, whose only material asset is its ownership of partnership interests of the Operating Partnership. As a result, the Parent Company does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing equity from time to time and guaranteeing the debt obligations of the Operating Partnership. The Operating Partnership holds substantially all the assets of the Company and directly or indirectly holds the ownership interests in the Company’s Real Estate Ventures. The Operating Partnership conducts the operations of the Company’s business and is structured as a partnership with no publicly traded equity. Except for net proceeds from equity issuances by the Parent Company, which are contributed to the Operating Partnership in exchange for partnership units, the Operating Partnership generates the capital required by the Company’s business through the Operating Partnership’s operations, by the Operating Partnership’s incurrence of indebtedness (directly and through subsidiaries) and through the issuance of partnership units of the Operating Partnership or equity interests in subsidiaries of the Operating Partnership.

The equity and non-controlling interests in the Parent Company and the Operating Partnership’s equity are the main areas of difference between the consolidated financial statements of the Parent Company and the Operating Partnership. The common units of limited partnership interest in the Operating Partnership are accounted for as partners’ equity in the Operating Partnership’s financial statements while the common units of limited partnership interests held by parties other than the Parent Company are presented as non-controlling interests in the Parent Company’s financial statements. The differences between the Parent Company and the Operating Partnership’s equity relate to the differences in the equity issued at the Parent Company and Operating Partnership levels.

2

To help investors understand the significant differences between the Parent Company and the Operating Partnership, thi s report presents the following as separate notes or sections for each of the Parent Company and the Operating Partnership:

| · | Consolidated Financial Statements; and

| · | Notes to the Parent Company’s and Operating Partnership’s Equity.

This report also includes separate Item 4. (Controls and Procedures) disclosures and separate Exhibit 31 and 32 certifications for each of the Parent Company and the Operating Partnership in order to establish that the Chief Executive Officer and the Chief Financial Officer of each entity have made the requisite certifications and that the Parent Company and Operating Partnership are compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934, as amended, and 18 U.S.C. § 1350.

In order to highlight the differences between the Parent Company and the Operating Partnership, the separate sections in this report for the Parent Company and the Operating Partnership specifically refer to the Parent Company and the Operating Partnership. In the sections that combine disclosures of the Parent Company and the Operating Partnership, this report refers to such disclosures as those of the Company. Although the Operating Partnership is generally the entity that directly or indirectly enters into contracts and real estate ventures and holds assets and incurs debt, reference to the Company is appropriate because the business is one enterprise and the Parent Company operates the business through the Operating Partnership.

The Parent Company is a self-administered and self-managed real estate investment trust (“REIT”) that provides leasing, property management, development, redevelopment, acquisition and other tenant-related services for a portfolio of office, retail and mixed-use properties. The Parent Company owns its assets and conducts its operations through the Operating Partnership and subsidiaries of the Operating Partnership. The Parent Company is the sole general partner of the Operating Partnership and, as of June 30, 2016, owned a 99.1% interest in the Operating Partnership. The Parent Company’s common shares of beneficial interest are publicly traded on the New York Stock Exchange under the ticker symbol “BDN”.

As of June 30, 2016, the Company owned 120 properties that contain an aggregate of approximately 18.1 million net rentable square feet and consist of 102 office properties, nine mixed-use properties, one retail property (112 properties, collectively the “Core Properties”), four development properties, two redevelopment properties and two properties classified as held for sale (collectively, the “Properties”). In addition, as of June 30, 2016, the Company owned economic interests in 16 unconsolidated real estate ventures (collectively, the “Real Estate Ventures”), of which eight own properties that contain approximately 7.9 million net rentable square feet of office space; two own 4.3 acres of undeveloped parcels of land; three own 2.2 acres of land under active development; one owns a residential tower that contains 345 apartment units and one owns an apartment complex that contains 398 units. Additionally, on June 30, 2016, one real estate venture, in which the Company owns a 50% interest, sold its interest in an office property, comprised of 172,286 square feet, located in Berwyn, Pennsylvania. As of June 30, 2016, the Company also owned 285 acres of undeveloped land and held options to purchase parcels containing approximately 50 additional acres of undeveloped land. As of June 30, 2016, the total potential development that these land parcels could support, including the parcels under option, under current zoning, entitlements or combination thereof, amounted to an estimated 6.3 million square feet.

Prior to the MAP Venture formation on February 4, 2016 (See Note 4, “Investment in Unconsolidated Real Estate Ventures”), the Company’s consolidated portfolio included 20 industrial properties. Upon consummation of the MAP Venture formation and as of June 30, 2016, the Company held six remaining industrial properties, which the Company classified as mixed-use.

The Company conducts its third-party real estate management services business primarily through wholly-owned management company subsidiaries. As of June 30, 2016, the management company subsidiaries were managing properties containing an aggregate of approximately 29.2 million net rentable square feet, of which approximately 18.0 million net rentable square feet related to Properties owned by the Company and approximately 11.2 million net rentable square feet related to properties owned by third parties and Real Estate Ventures.

Unless otherwise indicated, all references in this Form 10-Q to square feet represent net rentable area.

2. BASIS OF PRESENTATION

Basis of Presentation

The consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial statements. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, all adjustments (consisting solely of normal recurring matters) for a fair statement of the financial position of the Company as of June 30, 2016, the results of its operations for the three and six-month periods ended June 30, 2016 and 2015 and its cash flows for the six-month periods ended June 30, 2016 and 2015 have been included. The results of operations for such interim periods are not necessarily indicative of the results for a full year. These consolidated financial statements should be read in conjunction with the Parent Company’s and the Operating Partnership’s consolidated financial statements and footnotes included in their combined 2015 Annual Report on Form 10-K filed with the SEC on February 29, 2016.

On January 1, 2016, the Company adopted accounting guidance under Accounting Standards Codification (ASC) Topic 810, "Consolidation,” modifying the analysis it must perform to determine whether it should consolidate certain types of legal entities. The gui dance does not amend the existing disclosure requirements for variable interest entities (“VIEs”) or voting interest model entities. The guidance, however, modified the requirements to qualify under the voting interest model. Under the revised guidance, t he Operating Partnership is a variable interest entity of the Parent Company. As the Operating Partnership is alre ady consolidated in the balance sheets of the Parent Company, the identification of this entity as a variable interest entity has no impact on the consolidated financial statements of the Parent Company. There were no other legal entities qualifying under the scope of the revised guidance that were consolidated as a result of the adoption of this guidance. In addition, there were no other voti ng interest entities under prior existing guidance determined to be variable interest entities under the revised guidance.

The Company's Annual Report on Form 10-K for the year ended December 31, 2015 contains a discussion of our significant accounting policies under Note 2, "Summary of Significant Accounting Policies". There have been no significant changes in our significant accounting policies since December 31, 2015. Management discusses our significant accounting policies and management’s judgments and estimates with the Company's Audit Committee.

Recent Accounting Pronouncements

In May 2016, the Financial Accounting Standards Board (FASB) issued guidance amending the revenue from contracts with customers standard issued in May 2014 (and not yet effective). The amendments are intended to address implementation issues that were raised by stakeholders and discussed by the Joint Transition Resource Group, and provide additional practical expedients on collectability, noncash consideration, presentation of sales tax and contract modifications and completed contracts at transition. In accordance with the FASB election to defer the effective date of the revenue recognition standard by one year, reporting entities may choose to adopt the standard as of its original effective date or for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Calendar year-end reporting entities are therefore required to apply the new revenue guidance beginning in their 2018 interim and annual financial statements. The Company is in the process of evaluating the impact of this new guidance and has not yet determined the impact, if any, that the adoption of this guidance will have on its consolidated financial statements.

In March 2016, the FASB issued guidance intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. The new guidance allows for entities to make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. In addition, the guidance allows employers to withhold shares to satisfy minimum statutory tax withholding requirements up to the employees’ maximum individual tax rate without causing the award to be classified as a liability. The guidance also stipulates that cash paid by an employer to a taxing authority when directly withholding shares for tax-withholding purposes should be classified as a financing activity on the statement of cash flows. This guidance is effective for annual reporting periods beginning after December 15, 2016, and interim periods within that reporting period. Early adoption is permitted in any interim or annual period, with any adjustments reflected as of the beginning of the fiscal year of adoption. The Company is in the process of evaluating the impact of this new guidance and has not yet determined the impact, if any, that the adoption of this guidance will have on its consolidated financial statements.

Also in March 2016, the FASB issued guidance clarifying that a novation of party to a derivative instrument, whereby one of the parties to a derivative instrument is replaced with another party, does not, in and of itself, require de-designation of that hedging relationship provided that all other hedge criteria continue to be met. The guidance is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. An entity has an option to apply the amendments either on a prospective basis or on a modified retrospective basis. The Company is in the process of evaluating the impact of this new guidance and has not yet determined the impact, if any, that the adoption of this guidance will have on its consolidated financial statements.

In February 2016, the FASB issued guidance modifying the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard 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 by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. 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. Leases with a term of 12 months or less will be accounted for in the same manner as operating leases today. The new standard 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. The guidance supersedes previously issued guidance under ASC Topic 840 “Leases.” The guidance is effective on January 1, 2019, with early adoption permitted. The Company is in the process of evaluating the impact of this new guidance and has not yet determined the impact, if any, that the adoption of this guidance will have on its consolidated financial statements.

20

I n May 2014, the FASB issued the revenue from contracts with customers standard requiring revenue to be recognized in an amount that reflects the consideration expected to be received in exchange for goods and services. The standard requires the disclosure of sufficient quantitative and qualitative information for financial statement users to understand the nature, amount, timing and uncertainty of revenue and associated cash flows arising from contracts with customers. On July 9, 2015, the FASB elected to d efer the effective date of this revenue recognition standard by one year. Reporting entities may choose to adopt the standard as of the original effective date or for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Calendar year-end reporting entities are therefore required to apply the new revenue guidance beginning in their 2018 interim and annual financial statements. The Company is in the process of evaluating the impact of this new standard and has not ye t determined the impact, if any, th at the adoption of this standard will have on its con solidated financial statements.

Held for Use Impairment

During the three-month period ended June 30, 2016, the Company evaluated the recoverability of the carrying value of its properties under the undiscounted cash flow model. Based on the analysis, it was determined that due to the reduction in management’s intended hold period of a property located in the Metropolitan D.C. segment, the Company would not recover the carrying value of that property. Accordingly, the Company recorded an impairment charge on the property of $3.9 million at June 30, 2016, reducing the aggregate carrying value of the property from $37.4 million to its estimated fair value of $33.5 million. The Company measured this impairment based on a discounted cash flow analysis, using a hold period of 10 years and residual capitalization rate and discount rate of 7.75% and 8.25%, respectively. The results were compared to indicative pricing in the market. The assumptions used to determine fair value are Level 3 inputs in accordance with the fair value hierarchy established by Accounting Standards Codification (ASC) Topic 820, "Fair Value Measurements and Disclosures.”

During the three-month period ended March, 31, 2016, the Company evaluated the recoverability of the carrying value of its properties under the undiscounted cash flow model. Based on the analysis, it was determined that due to a reduction in management’s intended hold period, the Company would not recover the carrying value of two properties located in its Metropolitan D.C. segment. Accordingly, the Company recorded an impairment charge of $7.4 million at March 31, 2016 reducing the aggregate carrying values of these properties from $51.9 million to their estimated fair values of $44.5 million. The Company measured these impairments based on a discounted cash flow analysis, using a hold period of 10 years and residual capitalization rates and discount rates of 7.0%. The results were compared to indicative pricing in the market. The assumptions used to determine fair value are Level 3 inputs in accordance with the fair value hierarchy established by Accounting Standards Codification (ASC) Topic 820, "Fair Value Measurements and Disclosures.”

As of June 30, 2016, the Company determined that the sale of the property was probable and classified this property as held for sale in accordance with applicable accounting standards for long lived assets. At such date, the carrying value of the property exceeded the fair value less the anticipated costs of sale. As a result, the Company recognized an impairment loss totaling approximately $1.8 million during the three-month period ended June 30, 2016. The fair value measurement was based on the pricing in the purchase and sale agreement. As significant inputs to the model are unobservable, the Company determined that the value determined for this property falls within Level 3 fair value reporting.

(b) | During the three-month period ended June 30, 2016, the Company determined that the sale of a property located in Oakland, California, known as Oakland Lot B, was probable and classified it as held for sale in accordance with applicable accounting standards for long lived assets. As the fair value less anticipated costs to sell exceeded the carrying value of the property no impairment loss was recorded. The fair value measurement was based on pricing in the purchase and sale agreement. As the sales price is unobservable, the Company determined that the significant inputs used to value this property falls within Level 3 for fair value reporting.

The sales of the property and land referenced above as held for sale do not represent a strategic shift that has a major effect on the Company's operations and financial results. The operating results of these properties remain classified within continuing operations for all periods presented.

4. INVESTMENT IN UNCONSOLIDATED REAL ESTATE VENTURES

As of June 30, 2016, the Company held ownership interests in 16 unconsolidated Real Estate Ventures for an aggregate investment balance of $272.1 million. The Company formed or acquired interests in these Real Estate Ventures with unaffiliated third parties to develop or manage office, residential, and/or mixed-use properties or to acquire land in anticipation of possible development of office, residential and/or mixed-use properties. As of June 30, 2016, eight of the real estate ventures owned 73 office and 14 industrial buildings that contain an aggregate of approximately 7.9 million net rentable square feet; two real estate ventures owned 4.3 acres of undeveloped parcels of land; three real estate ventures owned 2.2 acres of land under active development; one real estate venture owned a residential tower that contains 345 apartment units and one real estate venture owned an apartment complex that contains 398 units. Additionally, on June 30, 2016, one real estate venture, in which the Company owns a 50% interest, sold its interest in an office property, comprised of 172,286 square feet, located in Berwyn, Pennsylvania. The proceeds from the sale had not been distributed to the Company at June 30, 2016 and, as a result, the carrying amount of the Company’s investment at the sale date remained on the balance sheet at June 30, 2016. See discussion under “1000 Chesterbrook” below for further information regarding this transaction.

The Company accounts for its unconsolidated interests in the Real Estate Ventures using the equity method. The Company’s unconsolidated interests range from 20% to 70%, subject to specified priority allocations of distributable cash in certain of the Real Estate Ventures.

The Company earned management fees from its Real Estate Ventures of $3.8 million and $7.2 million for the three- and six-month periods ended June 30, 2016 and $3.4 million and $6.0 million for the three- and six-month periods ended June 30, 2015, respectively. The Company has outstanding accounts receivable balances from its Real Estate Ventures of $1.5 million and $1.7 million as of June 30, 2016 and December 31, 2015, respectively.

The amounts reflected in the following tables (except for the Company’s share of equity and income) are based on the financial information of the individual Real Estate Ventures. The Company does not record operating losses of a Real Estate Venture in excess of its investment balance unless the Company is liable for the obligations of the Real Estate Venture or is otherwise committed to provide financial support to the Real Estate Venture.

The following is a summary of the financial position of the Real Estate Ventures as of June 30, 2016 and December 31, 2015 (in thousands):

| June 30, 2016 |  |  | December 31, 2015 |
Net property | $ | 1,457,952 |  |  | $ | 1,258,999 |
Other assets |  | 245,065 |  |  |  | 158,672 |
Other liabilities |  | 129,173 |  |  |  | 69,028 |
Debt, net |  | 985,326 |  |  |  | 794,571 |
Equity |  | 588,518 |  |  |  | 554,072 |
Company’s share of equity (Company’s basis) (a) (b) | $ | 272,148 |  |  | $ | 241,004 |

(a) | This amount includes the effect of the basis difference between the Company's historical cost basis and the basis recorded at the Real Estate Venture level, which is typically amortized over the life of the related assets and liabilities. Basis differentials occur from the impairment of investments, purchases of third party interests in existing Real Estate Ventures and upon the transfer of assets that were previously owned by the Company into a Real Estate Venture. In addition, certain acquisition, transaction and other costs may not be reflected in the net assets at the Real Estate Venture level.

(b) | Does not include the negative investment balance in one real estate venture totaling $1.1 million as of December 31, 2015, which is included in other liabilities. There is no negative investment balance as of June 30, 2016 because the Company sold its entire remaining 50% interest in the applicable real estate venture (See “Coppell Associates” section below) during the three month period ended March 31, 2016.

1000 Chesterbrook

On June 30, 2016, the real estate venture known as 1000 Chesterbrook sold its office property, comprised of 172,286 square feet, located in Berwyn, Pennsylvania for a sales price of $32.1 million. As of June 30, 2016, the Company owns a 50% interest in the 1000 Chesterbrook real estate venture. The proceeds to 1000 Chesterbrook, net of closing costs, pro-ration adjustments and $23.2 million of debt assumed by the buyer, were $9.8 million. The Company recorded $3.2 million for its proportionate share of the Venture’s gain which is reflected in “Gain on Real Estate Venture transactions” on the accompanying statement of operations. The proceeds from the sale, along with $0.2 million of working capital, had not been distributed to the Company as of June 30, 2016 and, as a result, the carrying amount of the Company’s investment in 1000 Chesterbrook, which amounted to $5.1 million at the sale date, remained on the balance sheet at June 30, 2016. See Note 14, "Subsequent Events," for information relating to the distribution.

evo at Cira Centre South Venture

On January 25, 2013, the Company formed HSRE-Campus Crest IX Real Estate Venture ("evo at Cira"), a joint venture among the Company and two unaffiliated third parties: Campus Crest Properties, LLC ("Campus Crest") and HSRE-Campus Crest IXA, LLC ("HSRE"). From formation through March 2, 2016, each of the Company and Campus Crest owned a 30% interest in evo at Cira and HSRE owned a 40% interest. At formation, the Company contributed to evo at Cira its tenancy rights under a long-term ground lease of one acre of land located in the University City submarket of Philadelphia, Pennsylvania, together with associated development rights, at an agreed-upon value of $8.5 million. During the three-month period ended September 30, 2014, evo at Cira completed construction of a 33-story, 850-bed student housing tower on the contributed one-acre ground lease. As of December 31, 2014, the Company and other members of evo at Cira had funded 100% of their respective shares of committed equity contributions and the real estate venture had fully drawn on its $97.8 million construction facility.

On March 2, 2016, the Company paid $12.8 million of cash and HSRE paid $6.6 million of cash to purchase Campus Crest’s entire 30% interest in evo at Cira and, as a result, each of the Company and HSRE owns a 50% interest in evo at Cira. Subsequent to the transaction, the Company’s investment basis in evo at Cira is $28.3 million. In conjunction with the purchase, the Company and HSRE entered into an amended and restated operating agreement to govern their rights and obligations as sole members of evo at Cira.

On June 10, 2016, evo at Cira refinanced its $97.8 million construction facility maturing July 25, 2016 with a $117.0 million term loan bearing interest at LIBOR + 2.25% capped at a total maximum interest of 5.25% and maturing on October 31, 2019, with options to extend the term to June 30, 2021. evo at Cira received an advance of $105.0 million at closing. The additional $12.0 million capacity under the term loan may be funded if certain criterion relating to the operating performance of the student housing tower are met. The term loan is secured by a leasehold mortgage that holds absolute assignment of leases and rents. Subsequent to refinancing and the receipt of amounts in escrow under the construction loan, evo at Cira distributed $6.3 million to the Company.

The Company accounted for its investment in evo at Cira under the equity method of accounting. Based upon the reconsideration event caused by the refinancing of evo at Cira’s construction facility, the Company reassessed its consolidation conclusion. The Company determined that this Real Estate Venture is no longer a VIE in accordance with the accounting standard for the consolidation of VIEs because evo at Cira, through the refinancing of the construction facility and without further support from the Company or HSRE, demonstrated that it has sufficient equity at risk to finance its activities. As a result, the Company used the voting interest model under the accounting standard for consolidation in order to determine whether to consolidate evo at Cira. Based upon each member's substantive participating rights over the activities that significantly impact the operations and revenues of evo at Cira under the operating agreement and related agreements, evo at Cira is not consolidated by the Company, and is accounted for under the equity method of

24

accounting. As a result of this transaction, the Company did not gain a controlling financial interest over evo at Cira; therefore, it was not required to remeasure its previously held equity interest to fair value at the date that it acquired the additional equity interest.

MAP Venture

On February 4, 2016, Brandywine Operating Partnership, L.P., together with subsidiaries of the Operating Partnership, entered into a series of related transactions (the “Och-Ziff Sale”) with affiliates of Och-Ziff Capital Management Group LLC (“Och-Ziff”) that resulted in the disposition by the Company of 58 office properties that contain an aggregate of 3,924,783 square feet for an aggregate purchase price of $398.1 million. The 58 properties are located in the Pennsylvania Suburbs, New Jersey/Delaware, Metropolitan Washington, D.C. and Richmond, Virginia segments. The related transactions involved: (i) the sale by the Company to MAP Fee Owner LLC, an affiliate of Och-Ziff (the “O-Z Land Purchaser”), of 100% of the Company’s fee interests in the land parcels (the “Land Parcels”) underlying the 58 office properties, together with rights to be the lessor under long-term ground leases (the “Ground Leases”) covering the Land Parcels; (ii) the Company’s formation of MAP Ground Lease Venture LLC (the “MAP Venture”) with MAP Ground Lease Holdings LLC, an affiliate of Och-Ziff (the “O-Z Venture Partner”), (iii) the Company’s sale to MAP Venture of the office buildings and related improvements (the “Buildings”) situated on the Land Parcels; and (iv) the retention of a 50% non-controlling equity interest in the MAP Venture.

The MAP Venture leases the Land Parcels from O-Z Land Purchaser through a ground lease that extends through February 2115. Annual payments by the MAP Venture, as tenant under the Ground Leases, initially total $11.9 million and increase 2.5% annually through November 2025.

At closing on February 4, 2016, the MAP Venture obtained a third party non-recourse debt financing of approximately $180.8 million secured by mortgages on the Buildings of the MAP Venture.

As a result of this transaction, the Company received $354.0 million in proceeds and maintains a 50% ownership interest in the MAP Venture valued as of February 4, 2016 at $25.2 million, which holds the leasehold interest in the Buildings. The MAP Venture was formed as a limited liability company in which the Company has been designated as the Managing Member. In addition, through an affiliate, the Company provides property management services at the Buildings on behalf of the MAP Venture for a market based management fee.

The Company has determined that the MAP Venture is a VIE in accordance with the accounting standard for consolidation of VIE’s. As a result, the Company used the VIE model under the accounting standard for consolidations to determine if it will consolidate the MAP Venture. Based on the provisions in the limited liability company agreement, the Company determined that it shares with O-Z Venture Partner the power to control the activities that most significantly impact the economics of the MAP Venture. Since control is shared, the Buildings were deconsolidated by the Company and accounted for under the equity method of accounting.

The Company is not required to fund the operating losses of the MAP Venture. Accordingly, it can only incur losses equal to its investment basis in MAP Venture.

The Company has determined that this transaction does not represent a significant shift in the Company’s operations that have a major impact on the Company’s economic performance. As a result, the properties are not classified as discontinued operations on the consolidated financial statements.

Coppell Associates

On January 29, 2016, the Company sold its entire 50% interest in an unconsolidated real estate venture known as Coppell Associates. The proceeds to the Company, net of closing costs and related debt payoff, were $4.6 million. The carrying amount of the Company’s investment in Coppell Associates amounted to a $1.1 million liability at the sale date, resulting in a $5.7 million gain on sale of its interest in the real estate venture. The investment was in a liability position because the Company, as a general partner, was required to fund losses of Coppell Associates. The negative investment balance represented the Company’s share of unfunded cumulative losses incurred in excess of its investment basis as of the date of sale.

Guarantees

As of June 30, 2016, the Company had provided guarantees on behalf of certain real estate ventures, consisting of (i) a $3.2 million payment guarantee on the $56.0 million construction loan for TB-BDN Plymouth Apartments; (ii) a several cost overrun guaranty on the $88.9 million construction loan for the development project being undertaken by 1919 Market Street LP; and (iii) a $0.5 million payment guarantee on a loan provided to PJP VII. In addition, during construction undertaken by real estate ventures, the Company has provided and expects to continue to provide cost overrun and completion guarantees, with rights of contribution among partners or members in the real estate ventures, as well as customary environmental indemnities and guarantees of customary exceptions to nonrecourse provisions in loan agreements. For additional information regarding these real estate ventures, see Note 4, "Investment in Unconsolidated Real

25

Estate Ventures," in the notes to the audited financial statements included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 201 5.

(a) | Represents the full debt amount of a property in a consolidated real estate venture in which the Company holds a 50% interest.

(b) | On April 7, 2016, the Company closed on an $86.9 million first mortgage financing on Two Logan Square, a 708,844-square foot office property located in Philadelphia, Pennsylvania. Proceeds of the loan were used to repay, without penalty, the $86.6 million principal balance of the former Two Logan Square first mortgage loan, which had a 7.57% effective interest rate.

27

(c)This loan was assumed upon acquisition of Two Commerce Square on December 19, 2013. The interest rate reflects the market rate at the time of acquisition. A default under this loan will also constitute a default under the loan outstanding on One Commerce Square, and a default under the One Commerce Square loan will also constitute a default under this loan. This loan is also secured by a lien on One Commerce Square and the loan on Two Commerce Square. (d)On January 14, 2016, the Company funded $265.8 million to prepay two mortgage loans, consisting of $176.9 million of principal repayment, $44.5 million in prepayment charges and a nominal amount of accrued interest, in repayment of the mortgage indebtedness on the office property located at 2970 Market Street in Philadelphia, Pennsylvania commonly known as 30th Street Main Post Office (“Cira Square”), ahead of its scheduled maturity date of September 10, 2030. Also on January 14, 2016, the Company funded $44.4 million, consisting of $35.5 million of principal repayment, $8.9 million in prepayment charges and a nominal amount of accrued interest, in repayment of the mortgage indebtedness of a 1,662 parking space facility located in Philadelphia, Pennsylvania commonly known as (“Cira South Garage”), ahead of its scheduled maturity date of September 10, 2030. These repayments were financed with $195.0 million of funds available under the unsecured revolving credit facility with the remaining balance funded through available cash balances. The Company recognized a $66.6 million loss on extinguishment of debt, consisting of the prepayment charges along with $10.8 million and $2.4 million related to non-cash charges for deferred financing costs for Cira Square and Cira South Garage, respectively. (e)On April 1, 2016, the entire principal balance of the 2016 6.00% Guaranteed Unsecured Notes was repaid upon maturity. Available cash balances were used to fund the repayment of the unsecured notes.

As of June 30, 2016, and December 31, 2015, the Company’s weighted-average effective interest rate on its mortgage notes payable was 4.04% and 5.72%, respectively. As of June 30, 2016 and December 31, 2015, the net carrying value of the Company’s Properties that are encumbered by mortgage indebtedness was $348.1 million and $562.7 million, respectively.

On May 15, 2015, the Company closed on a new four-year unsecured revolving credit facility that provides for borrowings of up to $600.0 million. The Company had no borrowings under its unsecured revolving credit facility as of June 30, 2016.

The Parent Company unconditionally guarantees the unsecured debt obligations of the Operating Partnership (or is a co-borrower with the Operating Partnership) but does not by itself incur unsecured indebtedness. The Parent Company has no material assets other than its investment in the Operating Partnership.

The Company was in compliance with all financial covenants as of June 30, 2016. Management continuously monitors the Company’s compliance with and anticipated compliance with the covenants. Certain of the covenants restrict management’s ability to obtain alternative sources of capital. While the Company currently believes it will remain in compliance with its covenants, in the event that the economy deteriorates in the future, the Company may not be able to remain in compliance with such covenants, in which case a default would result absent a lender waiver.

7. FAIR VALUE OF FINANCIAL INSTRUMENTS

Financial assets and liabilities recorded on the consolidated balance sheets are categorized based on the inputs to the valuation techniques as follows:

| · | Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access;

| · | Level 2 inputs are inputs, other than quoted prices included in Level 1, which are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals; and

| · | Level 3 inputs are unobservable inputs for the asset or liability, which is typically based on an entity’s own assumptions, as there is little, if any, related market activity or information.

The Company determined the fair values disclosed below using available market information and discounted cash flow analyses as of June 30, 2016 and December 31, 2015, respectively. The discount rate used in calculating fair value is the sum of the current risk free rate and the risk premium on the date of measurement of the instruments or obligations. Considerable judgment is necessary to interpret market data and to develop the related estimates of fair value. Accordingly, the estimates presented are not necessarily indicative of the amounts that the Company could realize upon disposition. The use of different estimates and valuation methodologies may have a material effect on the fair value amounts shown. The Company believes that the carrying amounts reflected in the consolidated balance sheets at June 30, 2016 and December 31, 2015 approximate the fair values for cash and cash equivalents, accounts receivable, other assets, accounts payable and accrued expenses. The following are financial instruments for which the Company’s estimates of fair value differ from the carrying amounts (in thousands):

| June 30, 2016 |  |  | December 31, 2015 |
| Carrying Amount |  |  | Fair Value |  |  | Carrying Amount |  |  | Fair Value |
Unsecured notes payable | $ | 1,363,770 |  |  | $ | 1,413,363 |  |  | $ | 1,512,554 |  |  | $ | 1,529,346 |
Variable rate debt | $ | 326,543 |  |  | $ | 305,383 |  |  | $ | 326,410 |  |  | $ | 305,522 |
Mortgage notes payable | $ | 344,308 |  |  | $ | 362,427 |  |  | $ | 545,753 |  |  | $ | 597,377 |

The fair value of the Company’s unsecured notes payable is categorized at a Level 2 basis (as provided by the accounting standard for Fair Value Measurements and Disclosures). This is because the Company valued these instruments using quoted market prices as of June 30, 2016 and December 31, 2015. For the fair value of the Company’s unsecured notes, the Company uses a discount rate based on the indicative new issue pricing provided by lenders.

The fair value of the Company’s mortgage notes payable and variable rate debt are all categorized at a Level 3 basis (as provided by the accounting standard for Fair Value Measurements and Disclosures). The fair value of the variable rate debt was estimated using a discounted cash flow analysis valuation on the borrowing rates currently available to the Company for loans with similar terms and maturities, as applicable. The fair value of the mortgage debt was determined by discounting the future contractual interest and principal

28

payments by a blended market rate for loans with similar terms, maturities and loan-t o-value. These financial instruments have been categorized as Level 3 because the Company considers the rates used in the valuation techniques to be unobservable inputs.

For the Company’s mortgage loans, the Company uses an estimate based discounted cash flow analyses and its knowledge of the mortgage market. The weighted average discount rate for the combined variable rate debt and mortgage loans used as to calculate fair value as of June 30, 2016 and December 31, 2015 was 4.480% and 4.550%, respectively. An increase in the discount rate used in the discounted cash flow model would result in a decrease to the fair value of the Company’s long-term debt. Conversely, a decrease in the discount rate used in the discounted cash flow model would result in an increase to the fair value of the Company’s long-term debt.

Disclosure about the fair value of financial instruments is based upon pertinent information available to management as of June 30, 2016 and December 31, 2015. Although management is not aware of any factors that would significantly affect the fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since June 30, 2016, and current estimates of fair value may differ from the amounts presented herein.

8. LIMITED PARTNERS' NON-CONTROLLING INTERESTS IN THE PARENT COMPANY

Non-controlling interests in the Parent Company’s financial statements relate to redeemable common limited partnership interests in the Operating Partnership held by parties other than the Parent Company and properties which are consolidated but not wholly owned.

Operating Partnership

The aggregate book value of the non-controlling interests associated with the redeemable common limited partnership interests in the accompanying consolidated balance sheet of the Parent Company as of June 30, 2016 and December 31, 2015 was $15.3 million and $16.1 million, respectively. Under the applicable accounting guidance, the redemption value of limited partnership units are carried at, on a limited partner basis, the greater of historical cost adjusted for the allocation of income and distributions or fair value. The Parent Company believes that the aggregate settlement value of these interests based on the number of units outstanding and the closing price of the common shares on the balance sheet dates as of June 30, 2016 and December 31, 2015, respectively, was approximately $24.9 million and $21.0 million.

9. FAIR VALUE OF DERIVATIVE FINANCIAL INSTRUMENTS

The following table summarizes the terms and fair values of the Company’s derivative financial instruments as of June 30, 2016 and December 31, 2015. The notional amounts provide an indication of the extent of the Company’s involvement in these instruments at that time, but do not represent exposure to credit, interest rate or market risks (amounts presented in thousands and included in other liabilities on the Company’s consolidated balance sheets).

Swap |  | Interest Rate |  | Cash Flow | (a) |  | 27,062 |  |  |  | 27,062 |  |  |  | 2.750 | % |  | December 21, 2011 |  | September 30, 2017 |  |  | (279 | ) |  |  | (201 | )
|  |  |  |  |  | $ | 328,610 |  |  | $ | 328,610 |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

(a) | Hedging unsecured variable rate debt.

The Company measures its derivative instruments at fair value and records them in the balance sheet as either an asset or liability. As of June 30, 2016, all swaps are included in other liabilities on the Company’s consolidated balance sheet.

Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. The Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

The Parent Company may sell common shares in amounts and at times to be determined by the Parent Company. Actual sales will depend on a variety of factors to be determined by the Parent Company, including, a mong others, market conditions, the trading price of the Company’s common shares and determinations by the Parent Company of the appropriate sources of funding. Sales agents engaged by the Parent Company under the Offering Program are entitled to receive a s compensation an aggregate, of up to 2% of the gross sales price per share sold under the Offering Program. From inception of the Offering Program through June 30, 2016, the Parent Company had not sold any shares under the program, leaving 16,000,000 rema ining shares available for sale.

Common Share Repurchases

The Parent Company maintains a share repurchase program under which the Board of Trustees has authorized the Parent Company to repurchase shares of its preferred and common stock with no expiration date. On July 22, 2015, the Parent Company's Board of Trustees authorized additional share repurchases of up to $100.0 million. Prior to the authorization 539,200 common shares were available for repurchase under the preexisting share repurchase program. The Company expects to fund the share repurchases with a combination of available cash balances and availability under our line of credit. As of June 30, 2016, 5,209,437 common shares have been repurchased and retired at an average purchase price of $12.90 per share and totaling $67.3 million. The timing and amounts of any purchases will depend on a variety of factors, including market conditions, regulatory requirements, share prices, capital availability and other factors as determined by our management team. The repurchase program does not require the purchase of any minimum number of shares and may be suspended or discontinued at any time without notice. There were no shares repurchased under the program during the six months ended June 30, 2016 or June 30, 2015.

Maryland law applicable to the Company does not contemplate treasury stock, and common shares repurchased under the program are accounted for as a reduction of common shares (at $0.01 par value per share) and a decrease to additional paid-in-capital.

12. SEGMENT INFORMATION

During the year ended December 31, 2015, the Company managed its portfolio within seven segments: (1) Pennsylvania Suburbs, (2) Philadelphia Central Business District (CBD), (3) Metropolitan Washington, D.C., (4) New Jersey/Delaware, (5) Richmond, Virginia, (6) Austin, Texas and (7) California. As a result of the Och-Ziff Sale that occurred on February 4, 2016, the Company narrowed its segments to five segments located in: (1) Pennsylvania Suburbs, (2) Philadelphia Central Business District (“CBD”), (3) Metropolitan Washington, D.C. and (4) Austin, Texas. The Och-Ziff Sale disposed of the entire Richmond, Virginia segment. Subsequent to the Och-Ziff Sale, the segments previously defined as New Jersey/Delaware and California are now being managed as a consolidated segment entitled (5) “Other,” as these geographies no longer provide a significant revenue contribution. The Pennsylvania Suburbs segment includes properties in Chester, Delaware, and Montgomery counties in the Philadelphia suburbs. The Philadelphia CBD segment includes properties located in the City of Philadelphia in Pennsylvania. The Metropolitan Washington, D.C. segment includes properties in the District of Columbia, Northern Virginia and southern Maryland. The Austin, Texas segment includes properties in the City of Austin, Texas. The Other segment includes properties in Burlington and Camden counties in New Jersey, properties in New Castle County in the state of Delaware, and properties in the City of Oakland and City of Concord in California. The corporate group is responsible for cash and investment management, development of certain real estate properties during the construction period, and certain other general support functions. Land held for development and construction in progress are transferred to operating properties by region upon completion of the associated construction or project.

Net operating income (“NOI”) is a non-GAAP financial measure defined as total revenue less property operating expenses, real estate taxes and third party management expenses. Segment NOI includes revenue, real estate taxes and property operating expenses directly related to operation and management of the properties owned and managed within the respective geographical region. Segment NOI excludes property level depreciation and amortization, revenue and expenses directly associated with third party real estate management services, expenses associated with corporate administrative support services, and inter-company eliminations. NOI also does not reflect general and administrative expenses, interest expenses, real estate impairment losses, depreciation and amortization costs, capital expenditures and leasing costs. Trends in development and construction activities that could materially impact the Company’s results from operations are also not reflected in NOI. All companies may not calculate NOI in the same manner. NOI is the measure that is used by the Company to evaluate the operating performance of its real estate assets by segment. The Company also believes that NOI provides useful information to investors regarding its financial condition and results of operations because it reflects only those income and expenses recorded at the property level. The Company believes that net income, as defined by GAAP, is the most appropriate earnings measure. The following is a reconciliation of consolidated NOI to consolidated net income (loss), as defined by GAAP (in thousands):

13. COMMITMENTS AND CONTINGENCIES

Legal Proceedings

The Company is involved from time to time in litigation on various matters, including disputes with tenants and disputes arising out of agreements to purchase or sell properties. Given the nature of the Company’s business activities, these lawsuits are considered routine to the conduct of its business. The result of any particular lawsuit cannot be predicted, because of the very nature of litigation, the litigation process and its adversarial nature, and the jury system. The Company will establish reserves for specific legal proceedings when it determines that the likelihood of an unfavorable outcome is probable and when the amount of loss is reasonably estimable. The

35

Company does not expect that the liabilities, if any, that may ultimately result from such legal actions will have a material adverse effec t on the consolidated financial position, results of operations or cash flows of the Company.

Letters-of-Credit

Under certain mortgages, the Company has funded required leasing and capital reserve accounts for the benefit of the mortgage lenders with letters-of-credit. There is an associated $10.0 million letter of credit for a mortgage lender at June 30, 2016. Certain of the tenant rents at properties that secure these mortgage loans are deposited into the loan servicer’s depository accounts, which are used to fund debt service, operating expenses, capital expenditures and the escrow and reserve accounts, as necessary. Any excess cash is included in cash and cash equivalents.

Environmental

As an owner of real estate, the Company is subject to various environmental laws of federal, state, and local governments. The Company’s compliance with existing laws has not had a material adverse effect on its financial condition and results of operations, and the Company does not believe it will have a material adverse effect in the future. However, the Company cannot predict the impact of unforeseen environmental contingencies or new or changed laws or regulations on its current Properties or on properties that the Company may acquire.

Ground Rent

Future minimum rental payments by the Company under the terms of all non-cancelable ground leases of land on which properties in the Company’s consolidated portfolio are situated are expensed on a straight-line basis regardless of when payments are due. The Company’s ground leases have remaining lease terms ranging from 5 to 73 years. Minimum future rental payments on non-cancelable leases at June 30, 2016 are as follows (in thousands):

Year |  | Minimum Rent |
2016 (six months remaining) |  | $ | 666 |
2017 |  |  | 1,334 |
2018 |  |  | 1,334 |
2019 |  |  | 1,334 |
2020 |  |  | 1,334 |
Thereafter |  |  | 67,632 |
Total |  | $ | 73,634 |

The Company obtained ground tenancy rights related to three properties in Philadelphia, Pennsylvania, which provide for contingent rent participation by the lessor in certain capital transactions and net operating cash flows of the properties after certain returns are achieved by the Company. Such amounts, if any, will be reflected as contingent rent when incurred. The leases also provide for payment by the Company of certain operating costs relating to the land, primarily real estate taxes. The above schedule of future minimum rental payments does not include any contingent rent amounts or any reimbursed expenses. Reference is made in our Annual Report on Form 10-K for the year ended December 31, 2015 for further detail regarding commitments and contingencies.

Put Option

On May 4, 2015, the Company entered into a put agreement in the ordinary course of business that grants an unaffiliated third party the unilateral option to require the Company to purchase a property, at a predetermined price, until May 4, 2018. In addition to the $35.0 million purchase price, the Company would be responsible for transaction and closing costs. There can be no assurance that the counterparty will exercise the option.

Fair Value of Contingent Consideration

On April 2, 2015, the Company purchased 618 Market Street in Philadelphia, Pennsylvania. The allocated purchase price included contingent consideration of $2.0 million payable to the seller upon commencement of development. The liability was initially recorded at fair value of $1.6 million and will accrete through interest expense to $2.0 million over the expected period until development is commenced. The fair value of this contingent consideration was determined using a probability weighted discounted cash flow model. The significant inputs to the discounted cash flow model were the discount rate and weighted probability scenarios. As the inputs are

36

unobservable, the Company determined the inputs us ed to value this liability fall within Level 3 for fair va lue reporting. As of June 3 0, 2016, the liability had accreted to $1.7 million. As there were no significant changes to the inputs, the liability remains within Level 3 for fair value reporting.

Debt Guarantees

As of June 30, 2016, the Company had provided guarantees on behalf of certain real estate ventures, consisting of (i) a $3.2 million payment guarantee on the $56.0 million construction loan for TB-BDN Plymouth Apartments; (ii) a several cost overrun guaranty on the $88.9 million construction loan for the development project being undertaken by 1919 Market Street LP; and (iii) a $0.5 million payment guarantee on a loan provided to PJP VII. See Note 4, "Investment in Unconsolidated Real Estate Ventures," in the notes to the financial statements for more information.

Other Commitments or Contingencies

On December 3, 2015, the Company entered into an agreement as development manager to construct Subaru of America’s (“Subaru”) corporate headquarters in Camden, New Jersey. The agreement provides the Company with the ability to earn additional profit if total project costs are less than the not-to-exceed (“NTE”) amount. The NTE amount, currently at $77.3 million, may be adjusted by change orders agreed upon by both Subaru and the Company. If construction costs are in excess of the NTE amount, the Company is obligated to pay such cost overruns. The terms of the guarantee do not provide a limitation on the costs the Company may be responsible for.

The Company invests in its properties and regularly incurs capital expenditures in the ordinary course to maintain the properties. The Company believes that such expenditures enhance its competitiveness. The Company also enters into construction, utility and service contracts in the ordinary course of business which may extend beyond one year. These contracts typically provide for cancellation with insignificant or no cancellation penalties.

Capital Expenditures

Amounts remaining to be incurred as of June 30, 2016 included the following:

| · | development and redevelopment obligations of $140.1 million; and

| · | capital expenditures for tenant improvements of $57.8 million.

14. SUBSEQUENT EVENTS

Garza Land Acquisition & Disposition

On July 1, 2016, the Company closed on the acquisition of 34.6 acres of land located in Austin, Texas known as the Garza Ranch for a gross purchase price of $20.6 million. The Company is currently under agreement to sell 9.5 acres (of the 34.6 acres) to two unaffiliated third parties.

1000 Chesterbrook Real Estate Venture

On July 14, 2016, the Company received a $5.1 million liquidating distribution from the 1000 Chesterbrook real estate venture. The cash distribution consists of proceeds from the sale of an office property on June 30, 2016 and was equal to the Company’s investment basis in 1000 Chesterbrook as of June 30, 2016.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The Private Securities Litigation Reform Act of 1995 (the “1995 Act”) provides a “safe harbor” for forward-looking statements. This Quarterly Report on Form 10-Q and other materials filed by us with the SEC (as well as information included in oral or other written statements made by us) contain statements that are forward-looking, including statements relating to business and real estate development activities, acquisitions, dispositions, future capital expenditures, financing sources, governmental regulation (including environmental regulation) and competition. We intend such forward-looking statements to be covered by the safe-harbor provisions of the 1995 Act. The words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “will,” “should” and similar expressions, as they relate to us, are intended to identify forward-looking statements. Although we believe that the expectations reflected in such forward-looking statements are based on reasonable assumptions, we can give no assurance that our expectations will be achieved. As forward-looking statements, these statements involve important risks, uncertainties and other factors that could cause actual results to differ materially from the expected results and, accordingly, such results may differ from those expressed in any forward-looking statements made by us or on our behalf. Factors that could cause actual results to differ materially from our expectations are set forth in our Annual Report under the heading “Forward-Looking Statements” in our Annual Report on Form 10-K for the year ended December 31, 2015.

Given these uncertainties, and the other risks identified in the “Risk Factors ” section of our Annual Report on Form 10-K for the year ended December 31, 2015, we caution readers not to place undue reliance on forward-looking statements. We assume no obligation to update or supplement forward-looking statements that become untrue because of subsequent events.

The discussion that follows is based primarily on our consolidated financial statements as of June 30, 2016 and December 31, 2015 and for the three- and six-month periods ended June 30, 2016 and 2015 and should be read along with the consolidated financial statements and related notes appearing elsewhere in this report. The ability to compare one period to another may be significantly affected by acquisitions completed, development properties placed in service and dispositions made during those periods.

OVERVIEW

As of June 30, 2016, we owned 120 properties, consisting of 102 office properties, nine mixed-use properties, one retail property (112 properties, collectively the “Core Properties”), four development properties, two redevelopment properties and two properties classified as held for sale (collectively, the “Properties”) containing an aggregate of approximately 18.1 million net rentable square feet. In addition, as of June 30, 2016, we owned economic interests in 16 unconsolidated real estate ventures that contain approximately 7.9 million net rentable square feet (collectively, the “Real Estate Ventures”). As of June 30, 2016, we also owned 285 acres of undeveloped land and held options to purchase parcels containing approximately 50 additional acres of undeveloped land. As of June 30, 2016, the total potential development that these land parcels could support, under current zoning, entitlements or combination thereof, amounted to an estimated 6.3 million square feet. The Properties and the properties owned by the Real Estate Ventures are located in or near Philadelphia, Pennsylvania; Metropolitan Washington, D.C.; Southern New Jersey; Richmond, Virginia; Wilmington, Delaware; Austin, Texas and Oakland and Concord, California. In addition to managing properties that we own, as of June 30, 2016, we were managing approximately 11.2 million net rentable square feet of office and industrial properties for third parties and Real Estate Ventures.

Prior to the MAP Venture formation (see Note 4, “Investment in Unconsolidated Real Estate Ventures” to the consolidated financial statements), we held 20 industrial properties. Subsequent to the transactions, we hold six remaining industrial properties which have been classified as mixed-use.

We conduct our third-party real estate management services business primarily through wholly-owned management company subsidiaries. As of June 30, 2016, the management company subsidiaries were managing properties containing an aggregate of approximately 29.2 million net rentable square feet, of which approximately 18.0 million net rentable square feet related to Properties that we own and consolidate and approximately 11.2 million net rentable square feet related to properties owned by third parties and the Real Estate Ventures.

During the six months ended June 30, 2016, we were managing our portfolio within five markets; (1) Pennsylvania Suburbs, (2) Philadelphia Central Business District (“CBD”), (3) Metropolitan Washington, D.C. (4) Austin, Texas and (5) Other. Subsequent to the Och-Ziff Sale, the markets previously defined as New Jersey/Delaware and California are now being managed as a consolidated segment entitled “Other,” as these geographies no longer provide a significant revenue contribution. The Pennsylvania Suburbs segment includes properties in Chester, Delaware and Montgomery counties in the Philadelphia suburbs. The Philadelphia CBD segment includes properties located in the City of Philadelphia in Pennsylvania. The Metropolitan Washington, D.C. segment includes properties in Northern Virginia, Washington, D.C. and southern Maryland. The Austin, Texas segment includes properties in the City of Austin, Texas. The Other segment includes properties in Burlington and Camden counties in New Jersey, properties in New Castle county in the state of Delaware and properties in the City of Oakland and City of Concord in California. Our corporate group is responsible for cash

38

and investment management, development of certain real estate properties during the construction period, and certain other general support functions.

We generate cash and revenue from leases of space at our properties and, to a lesser extent, from the management of properties owned by third parties and from investments in the Real Estate Ventures. Factors that we evaluate when leasing space include rental rates, costs of tenant improvements, tenant creditworthiness, current and expected operating costs, the length of the lease term, vacancy levels and demand for office space. We also generate cash through sales of assets, including assets that we do not view as part of our Core Properties, either because of location or expected growth potential, and assets that are commanding premium prices from third party investors.

Our financial and operating performance is dependent upon the demand for office and other commercial space in our markets, our leasing results, our acquisition, disposition and development activity, our financing activity, our cash requirements and economic and market conditions, including prevailing interest rates.

Adverse changes in economic conditions could reduce the availability of financing and potentially increase borrowing costs; lead to declines in demands for office and other commercial space and result in rental rate declines; and adversely impact tenant credit quality.

Overall economic conditions, including but not limited to deteriorating financial and credit markets, could have a dampening effect on the fundamentals of our business, including increases in past due accounts, tenant defaults, lower occupancy and reduced effective rents. These conditions would negatively affect our future net income and cash flows and could have a material adverse effect on our financial condition. We believe that the quality of our assets and our strong balance sheet will enable us to raise debt capital, if necessary, in various forms and from different sources, including traditional term or secured loans from banks, pension funds and life insurance companies. However, there can be no assurance that we will be able to borrow funds on terms that are economically attractive or at all.

We continue to seek revenue growth throughout our portfolio by increasing occupancy and rental rates. Occupancy at our Core Properties at June 30, 2016 was 92.1% compared to 91.7% at June 30, 2015.

The table below summarizes selected operating and leasing statistics of our Core Properties for the three- and six-month periods ended June 30, 2016 and 2015:

In seeking to increase revenue through our operating, financing and investment activities, we also seek to minimize operating risks, including (i) tenant rollover risk, (ii) tenant credit risk and (iii) development risk.

39

Tenant Rollover Risk

We are subject to the risk that tenant leases, upon expiration, will not be renewed, that space may not be relet, or that the terms of renewal or reletting (including the cost of renovations) may be less favorable to us than the current lease terms. Leases that accounted for approximately 1.4% of our aggregate final annualized base rents as of June 30, 2016 (representing approximately 1.8% of the net rentable square feet of the properties) are scheduled to expire without penalty in 2016. We maintain an active dialogue with our tenants in an effort to maximize lease renewals. For our Core Properties, the retention rate for the three- and six-month periods ended June 30, 2016 was 73.0% and 63.2% compared to a retention rate of 78.2% and 74.0% for the three- and six-month periods ended June 30, 2015. The lower relative retention primarily resulted from the natural expiration of a lease for a large tenant in our Pennsylvania Suburbs segment. Rental rates on leases expiring during 2016 do not deviate significantly from market renewal rates in the regions in which we operate. If we are unable to renew leases or relet space under expiring leases, at anticipated rental rates, or if tenants terminate their leases early, our financial position, net income and cash flow would be adversely impacted.

Tenant Credit Risk

In the event of a tenant default, we may experience delays in enforcing our rights as a landlord and may incur substantial costs in protecting our investment. Our management regularly evaluates our accounts receivable reserve policy in light of our tenant base and general and local economic conditions. Our accounts receivable allowance was $15.4 million or 9.1% of total receivables (including accrued rent receivables) as of June 30, 2016 compared to $16.2 million or 9.1% of total receivables (including accrued rent receivables) as of December 31, 2015.

If economic conditions deteriorate, we may experience increases in past due accounts, defaults, lower occupancy and reduced effective rents. This condition would negatively affect our future net income and cash flows and could have a material adverse effect on our financial condition.

Development Risk

Development projects are subject to a variety of risks, including construction delays, construction cost overruns, inability to obtain financing on favorable terms, inability to lease space at projected rates, inability to enter into construction, development and other agreements on favorable terms, and unexpected environmental and other hazards.

As of June 30, 2016, the following development properties and joint venture development projects remain under construction (in thousands, except square footage/acreage and number of buildings):

Wholly Owned Developments:

(a) | The building was placed into service during the three-month period ended June 30, 2016 and, as of June 30, 2016, 45.2% of apartment units had been leased and 25.9% were occupied.

Reference is made to our Annual Report on Form 10-K for the year ended December 31, 2015 for project overviews, as well as risks associated with these development projects. See Item 2., "Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources – Contractual Obligations" for contractual commitments relating to our ongoing development projects.

On May 29, 2015, we and an unaffiliated third party, JBG/DC Manager, LLC ("JBG"), formed 51 N 50 Patterson, Holdings, LLC Venture ("51 N Street") and 1250 First Street Office, LLC Venture ("1250 First Street") (collectively the “JBG Ventures”). The JBG Ventures expect to develop three buildings in Washington, D.C. For further information see Item 1., "Business - Developments" included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015. The above table does not include amounts related to these developments because the scope of development project has not been finalized as of June 30, 2016.

In addition, the above table does not include amounts related to the Schuylkill Yards Project. See Item 2.,“Management’s Discussion and Analysis of Financial Condition and Results of Operations – Overview – Development Risk," for further details.

Third Party Developments:

On May 9, 2016, we entered into a master development agreement (the “Development Agreement”) with Drexel University, a Pennsylvania non-profit corporation (“Drexel”), that provides for our rights and obligations, as master developer, of a multi-phase, multi-component development on approximately 10.11 acres of land (the “Development Site”) owned by Drexel and adjacent to Drexel’s main campus in the University City section of Philadelphia. We refer to the overall development, including the Development Site and four adjacent acres comprising the master planned area as the “Schuylkill Yards Project.”

The Schuylkill Yards Project is contemplated to be developed in six phases over an approximately 20-year period, excluding extension options, and to consist of an aggregate of approximately 5.1 million of floor area ratio, or FAR, of commercial, office, educational, research, residential, and other facilities, as well as accessory green spaces.

Prior to commencement of construction of the initial facility, we will oversee master planning, including obtaining required government and third party approvals, and completing confirmatory real estate due diligence. Thereafter, upon commencement, we or a qualifying designee will enter into a 99-year ground lease with Drexel for the portion of the Development Site where the initial facility will be constructed. We will enter into similar ground leases with Drexel covering additional portions of the Development Site in connection with our construction of additional facilities under subsequent phases of the Schuylkill Yards Project. We currently anticipate incurring approximately $10 million to $15 million in costs over the next 18 to 24 months, primarily to obtain zoning, land-use and other approvals and to develop park area associated with the Development Site.

We currently anticipate commencement of construction of the initial phase on or about the first half of 2018 and completion in or about the fourth quarter of 2019. We contemplate that the initial phase will consist of a mixed-use facility containing approximately 700,000 FAR, and with office space comprising at least 60% of the FAR at such facility. As of the date of this Form 10-Q, we have not finalized the scope of the development or entered into construction contracts.

Actual timing and scope of subsequent phases of development will depend on timing and scope of prior phases, third party approvals and design and development-related determinations by Drexel and us. Overall, approximately 50% of the FAR would consist of office, educational and research space, and the balance would consist of residential, retail, hospitality and parking.

We intend to fund the costs to develop each development phase of the Schuylkill Yards Project through a combination of cash on hand, capital raised through one or more joint venture formations, and proceeds from the sale of other assets or debt financing, including project-specific mortgage financing. As of the date of this Form 10-Q, we have not entered into agreements with third parties for joint venture participation in the project.

The Development Agreement provides for rights, responsibilities and restrictions relating to all phases of the project, including but not limited to design and construction; leasing of space; involvement of third party participants; extension and termination rights; and protocols for reaching agreement on subjects customary for long-term collaborative development projects.

On December 3, 2015, we entered into an agreement as development manager to construct Subaru of America’s corporate headquarters (the “Subaru Headquarters Development”), an office property containing five floors and approximately 250,000 square feet, on land owned by Subaru and located in Camden, New Jersey. In addition to development fees, the agreement provides us the ability to earn additional profit if total project costs are less than the not-to-exceed (“NTE”) amount. The NTE amount, currently at $77.3 million, may

41

be adjusted by change orders agreed upon by both Subaru and us. If construction costs are in excess of the NTE amount, we are obligated to pay such cost overruns.

Land Holdings

As of June 30, 2016, we owned approximately 285 acres of undeveloped land, and held options to purchase approximately 50 additional acres of undeveloped land. As market conditions warrant, we will seek to opportunistically dispose of those parcels that we do not anticipate developing. For parcels of land that we ultimately develop, we will be subject to risks and costs associated with land development, including building moratoriums and the inability to obtain necessary zoning, land-use, building, occupancy and other required governmental approvals, construction cost increases or overruns and construction delays, and insufficient occupancy rates and rental rates. As of June 30, 2016, the total potential development that these land parcels could support, under current zoning and entitlements, amounted to 6.3 million square feet of development, inclusive of the options to purchase approximately 50 additional acres of undeveloped land.

Impairments and Disposal of Long-Lived Assets

We review our long-lived assets for impairment following the end of each quarter using cash flow projections and estimated fair values for each of the properties included within our impairment analysis. We update leasing and other assumptions regularly, paying particular attention to properties where there is an event or change in circumstances that indicates an impairment in value. For long-lived assets to be held and used, we analyze recoverability based on the estimated undiscounted future cash flows expected to be generated from the operations and eventual disposition of the assets over, in most cases, a 10-year hold period. If there is significant possibility that we will dispose of assets earlier, we analyze the recoverability using a probability weighted analysis of the undiscounted future cash flows expected to be generated from the operations and eventual disposition of each asset using various possible hold periods. If the recovery analysis indicates that the carrying value of the tested property is not recoverable, the property is written down to its fair value and an impairment loss is recognized. In such case, an impairment loss is recognized in the amount of the excess of the carrying amount of the asset over its fair value. If and when our plans change, we revise our recoverability analysis to use cash flows expected from operations and eventual disposition of each asset using hold periods that are consistent with our revised plans.

Estimated cash flows used in such analysis are based on our plans for the property and our views of market economic conditions. The estimates consider factors such as current and future rental rates, occupancies for the tested property and comparable properties, estimated operating and capital expenditures and recent sales data for comparable properties. Most of these factors are influenced by market data obtained from real estate leasing and brokerage firms and our direct experience with the properties and their markets.

We generally consider assets to be “held for sale” when the transaction has been approved by our Board of Trustees, or by officers vested with authority to approve the transaction and there are no known significant contingencies relating to the sale of the property within one year of the consideration date and the consummation of the transaction is otherwise considered probable. When a property is designated as held for sale, we stop depreciating the property and estimate the property’s fair value, net of selling costs. If the determination is made that the estimated fair value, net of selling costs, is less than the net book value of the property, an impairment loss is recognized equal to the difference and reduces the net book value of the property. For periods in which a property is classified as held for sale, we classify the assets of the property as held for sale on the consolidated balance sheet for such periods.

The relevant accounting guidance for impairments requires that qualifying assets and liabilities and the results of operations that have been sold, or otherwise qualify as “held for sale,” be presented as discontinued operations in all periods presented if the disposal represents a strategic shift that has, or will have, a major effect on our operations and financial results. If deemed a discontinued operation, then the components of the property’s net income that are reflected as discontinued operations include net gain (or loss) on disposition of real estate, operating results, depreciation and interest expense (if the property is subject to a secured loan).

During the three-month period ended June 30, 2016, we evaluated the recoverability of the carrying value of our properties under the undiscounted cash flow model. Based on the analysis, it was determined that due to the reduction in management’s intended hold period of one property located in the Metropolitan, D.C. segment, we would not recover the carrying value of that property. Accordingly, we recorded an impairment charge on the property located in Metropolitan D.C. of $3.9 million at June 30, 2016, reducing the aggregate carrying value of the property from $37.4 million to its estimated fair value of $33.5 million.

On June 1, 2016, we entered into an agreement to sell an office property containing 95,183 square feet at 1120 Executive Boulevard located in Mount Laurel, New Jersey. As of June 30, 2016, we determined that the sale of the property was probable and classified this property as held for sale in accordance with applicable accounting standards for long lived assets. At such date, the carrying value of the property exceeded the fair value less the anticipated costs of sale. As a result, we recognized an impairment loss totaling approximately $1.8 million during the three-month period ended June 30, 2016. The fair value measurement was based on the pricing in the sales agreement.

During the three-month period ended March 31, 2016, we evaluated the recoverability of the carrying value of our properties utilizing an undiscounted cash flow model. Based on our evaluation, we determined that due to a reduction in the intended hold period for two of our

properties in the Metropolitan D.C. s egment, we would not recover the carrying value of these properties. Accordingly, we recorded an impairment charge of $7.4 million at March 31, 2016 reducing the aggregate carrying values of these properties from $51.9 million to their estimated fair value of $44.5 million.

Equity Method Investments in Unconsolidated Real Estate Ventures

Under the equity method, investments in unconsolidated Real Estate Ventures are recorded initially at cost, as investments in Real Estate Ventures, and subsequently adjusted for equity in earnings, cash contributions, less distributions and impairments. For Real Estate Ventures that are constructing assets to commence planned principal operations, we capitalize interest expense using our weighted average interest rate and our investment balance as a basis. Planned principal operations commence when a property is available to lease and at that point in time we cease capitalizing interest to our investment basis.

On a quarterly basis, management assesses whether there are any indicators that the value of our investments in unconsolidated joint ventures may be impaired. An investment is impaired only if management’s estimate of the value of the investment is less than the carrying value of the investment, and such decline in value is deemed to be other than temporary. To the extent impairment has occurred, the loss shall be measured as the excess of the carrying amount of the investment over the fair value of the investment. Our estimates of value for each investment (particularly in commercial real estate joint ventures) are based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for tenants, changes in market rental rates, and operating costs. These factors are difficult to predict and are subject to future events that may alter management’s assumptions; accordingly, the values estimated by management in its impairment analyses may not be realized.

(d) | During the three-month period ended December 31, 2015, we recognized an impairment loss totaling approximately $45.4 million on the properties. The loss on sale represents additional closing costs recognized at settlement.

On January 15, 2016, we sold 120 acres located in Berks County Pennsylvania for a sales price of $0.9 million. The land was classified as held for sale as of December 31, 2015. The carrying value of the land exceeded the fair value less the anticipated costs of sale, therefore we recognized an impairment loss of $0.3 million during the three-month period ended December 31, 2015. There was no gain or loss recognized on the sale during 2016.

The disposal of the properties and land referenced above do not represent a strategic shift that has a major effect on our operations and financial results. Accordingly, the operating results of these properties remain classified within continuing operations for all periods presented.

| (a) | On June 1, 2016, we entered into an agreement to sell an office property containing 95,183 square feet at 1120 Executive Boulevard located in Mount Laurel, New Jersey. As of June 30, 2016, we determined that the sale of the property was probable and classified this property as held for sale in accordance with applicable accounting standards for long lived assets. At such date, the carrying value of the property exceeded the fair value less the anticipated costs of sale. As a result, we recognized an impairment loss totaling approximately $1.8 million during the three-month period ended June 30, 2016. The fair value measurement was based on the pricing in the sales agreement.

| (b) | During the three-month period ended June 30, 2016, we determined that the sale of a property located in Oakland, California, known as Oakland Lot B, was probable and classified it as held for sale in accordance with applicable accounting standards for long lived assets. As the fair value less anticipated costs to sell exceeded the carrying value of the property no impairment loss was recorded.

933 First Avenue, King of Prussia, Pennsylvania

During the three-month period ended March 31, 2016, we entered into a lease and commenced construction on an 111,000 square foot building at 933 First Avenue in King of Prussia, Pennsylvania. The project is 100% preleased to a single tenant under a 12-year lease. Estimated construction costs total $29.2 million, with delivery anticipated in the second quarter of 2017. We expect to fund the project with available cash balances and/or our unsecured revolving credit facility.

1000 Chesterbrook

On June 30, 2016, the real estate venture known as 1000 Chesterbrook sold its office property comprised of 172,327 square feet, located in Berwyn, Pennsylvania for a sales price of $32.1 million. As of June 30, 2016, we own a 50% interest in the 1000 Chesterbrook real estate venture. The proceeds to 1000 Chesterbrook, net of closing costs, pro-ration adjustments and $23.2 million of debt assumed by the buyer, were $9.8 million. We recorded $3.2 million for our proportionate share of the Venture’s gain which is reflected in “Gain on Real Estate Venture transactions” on the accompanying statement of operations. The proceeds from the sale, along with $0.2 million of working capital, had not been distributed to us as of June 30, 2016 and, as a result, the carrying amount of our investment in 1000 Chesterbrook, which amounted to $5.1 million at the sale date remained on the balance sheet at June 30, 2016.

evo at Cira Centre South Venture

On January 25, 2013, we formed HSRE-Campus Crest IX Real Estate Venture ("evo at Cira"), a joint venture among us and two unaffiliated third parties: Campus Crest Properties, LLC ("Campus Crest") and HSRE-Campus Crest IXA, LLC ("HSRE"). From formation through March 2, 2016, each of us and Campus Crest owned a 30% interest in evo at Cira and HSRE owned a 40% interest. At formation, we contributed to evo at Cira our tenancy rights under a long-term ground lease of one acre of land located in the University City submarket of Philadelphia, Pennsylvania, together with associated development rights, at an agreed-upon value of $8.5 million. During the three-month period ended September 30, 2014, evo at Cira completed construction of a 33-story, 850-bed student housing tower on the contributed one acre ground lease. As of December 31, 2014, we and other members of evo at Cira had funded 100% of our and their respective shares of committed equity contributions and the real estate venture had fully drawn on its $97.8 million construction facility.

44

On March 2, 2016, we paid $12.8 million of cash and HSRE paid $6.6 million of c ash to purchase Campus Crest’s entire 30% interest in evo at Cira and, as a result, each of us and HSRE own s a 50% interest in evo at Cira. Subsequent to the transaction, our investment basis in evo at Cira is $28.3 million. In conjunction with the purchas e, each of us and HSRE entered into an amended and restated operating agreement to govern our rights and obligations as sole members of evo at Cira.

On June 10, 2016, evo at Cira refinanced its $97.8 million construction loan maturing July 25, 2016 with a $117.0 million term loan bearing interest at LIBOR + 2.25% capped at a total maximum interest of 5.25% and maturing on October 31, 2019, with options to extend the term to June 30, 2021. evo at Cira received an advance of $105.0 million at closing. The additional $12.0 million capacity under the term loan may be funded if certain criterion relating to the operating performance of the student housing tower are met. The term loan is secured by a leasehold mortgage that holds absolute assignment of leases and rents. Subsequent to refinancing and the receipt of amounts in escrow under the construction loan, $6.3 million was distributed us.

MAP Venture

On February 4, 2016, we entered into a series of related transactions with affiliates of Och-Ziff Capital Management Group LLC (“Och-Ziff”) that resulted in the disposition of 58 properties that contain an aggregate of 3,924,783 square feet for an aggregate purchase price of $398.1 million. The 58 properties are located in the Pennsylvania Suburbs, New Jersey/Delaware, Metropolitan Washington, D.C. and Richmond, Virginia segments. The related transactions involved: (i) the sale by us to MAP Fee Owner LLC, an affiliate of Och-Ziff (the “O-Z Land Purchaser”), of 100% of our fee interests in the land parcels (the “Land Parcels”) underlying the 58 office properties, together with rights to be the lessor under long-term ground leases (the “Ground Leases”) covering the Land Parcels; (ii) our formation of MAP Ground Lease Venture LLC (the “MAP Venture”) with MAP Ground Lease Holdings LLC, an affiliate of Och-Ziff (the “O-Z Venture Partner”), (iii) our sale to the MAP Venture of the office buildings and related improvements (the “Buildings”) situated on the Land Parcels; and (iv) our retention of a 50% non-controlling equity interest in the MAP Venture.

The MAP Venture leases the Land Parcels from O-Z Land Purchaser through a ground lease that extends through February, 2115. Annual payments by the MAP Venture, as tenant under the ground leases, initially total $11.9 million and increase 2.5% annually through November 2025.

At closing, the MAP Venture obtained a third party non-recourse debt financing of approximately $180.8 million secured by mortgages on the Buildings of the MAP Venture.

As a result of this transaction, we received $354.0 million in proceeds and maintain a 50% ownership interest in the MAP Venture, valued as of February 4, 2016 at $25.2 million, which holds the leasehold interest in the Buildings. The MAP Venture was formed as a limited liability company in which we have been designated as the Managing Member. We provide property management services at the Buildings on behalf of the MAP Venture for a market based management fee.

We are not required to fund the operating losses of the MAP Venture. Accordingly, we can only incur losses up to our investment basis in the joint venture.

We have determined that this transaction does not represent a significant shift in our operations that has a major impact on our economic performance and, as a result, the properties are not classified as discontinued operations on the consolidated financial statements.

Coppell Associates

On January 29, 2016, we sold our entire 50% ownership interest in an unconsolidated real estate venture known as Coppell Associates. The proceeds to us, net of closing costs and related debt payoff, were $4.6 million. The carrying amount of our investment in Coppell Associates amounted to a $1.1 million liability at the sale date, resulting in a $5.7 million gain on sale of our interest in the real estate venture. Our investment was in a liability position because, as a general partner, we were required to fund losses of Coppell Associates. The negative investment balance represented our share of unfunded cumulative losses incurred in excess of our investment basis as of the date of sale.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Management’s Discussion and Analysis of Financial Condition and Results of Operations discuss our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). The preparation of these financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Certain accounting policies are considered to be critical accounting policies, as they require management to make assumptions about matters that are highly uncertain at the time the estimate is made and changes in accounting estimate are reasonably likely to occur from period to period. Management bases its estimates and assumptions on historical experience and current economic conditions.

45

Our Annual Report on Form 10-K for the year ended December 31, 201 5 contains a discussion of our critical accounting policies. There have been no significant changes in our critical accounting policies since December 31, 201 5. See also Note 2, "Basis of Presentation," in our unaudi ted consolidated fi nancial statements for the three- and six-month period s ended June 30, 2016 and 2015, set forth herein.

RESULTS OF OPERATIONS

The following discussion is based on our consolidated financial statements for the three- and six-month periods ended June 30, 2016 and 2015. We believe that presentation of our consolidated financial information, without a breakdown by segment, will effectively present important information useful to our investors.

Net operating income (“NOI”) as presented in the comparative analysis below is a non-GAAP financial measure defined as total revenue less property operating expenses, real estate taxes and third party management expenses. Property operating expenses that are included in determining NOI consist of costs that are necessary and allocable to our operating properties such as utilities, property-level salaries, repairs and maintenance, property insurance, management fees and bad debt expense. General and administrative expenses that are not reflected in NOI primarily consist of corporate-level salaries, amortization of share awards and professional fees that are incurred as part of corporate office management. NOI is a non-GAAP financial measure that we use internally to evaluate the operating performance of our real estate assets by segment, as presented in Note 12, "Segment Information," to our consolidated financial statements, and of our business as a whole. We believe NOI provides useful information to investors regarding our financial condition and results of operations because it reflects only those income and expense items that are incurred at the property level. While NOI is a relevant and widely used measure of operating performance of real estate investment trusts, it does not represent cash flow from operations or net income as defined by GAAP and should not be considered as an alternative to those measures in evaluating our liquidity or operating performance. NOI does not reflect interest expenses, real estate impairment losses, depreciation and amortization costs, capital expenditures and leasing costs. We believe that net income, as defined by GAAP, is the most appropriate earnings measure. See Note 12, "Segment Information," to the consolidated financial statements for a reconciliation of NOI to our consolidated net income (loss) as defined by GAAP.

Comparison of the Three-Month Periods Ended June 30, 2016 and June 30, 2015

The table below shows selected operating information for the “Same Store Property Portfolio” and the “Total Portfolio.” The Same Store Property Portfolio consists of 105 properties containing an aggregate of approximately 15.5 million net rentable square feet, and represents properties that we owned for the entire three-month periods ended June 30, 2016 and 2015. The Total Portfolio includes the effects of other properties that were either placed into service, acquired or redeveloped after January 1, 2015 and disposed of prior to June 30, 2016 or classified as held for sale as of June 30, 2016. A property is excluded from our Same Store Property Portfolio and moved into the redevelopment column in the period that we determine that a redevelopment would be the best use of the asset, and when said asset is taken out of service or is undergoing re-entitlement for a future development strategy. This table also includes a reconciliation from the Same Store Property Portfolio to the Total Portfolio net income (i.e., all properties owned by us during the three-month periods ended June 30, 2016 and 2015) by providing information for the properties which were acquired, placed into service, under development or redevelopment and administrative/elimination information for the three-month periods ended June 30, 2016 and 2015 (in thousands).

The Total Portfolio net income presented in the table is equal to the net income of the Parent Company and the Operating Partnership.

Total Revenue

Cash rents from the Total Portfolio decreased by $18.0 million during the second quarter of 2016 compared to the second quarter of 2015, primarily attributable to:

| · | $22.9 million decrease due to the disposition of 86 properties from the second quarter of 2015 through the second quarter of 2016; offset by,

| · | $1.1 million increase in the Same Store Property Portfolio due to a 0.5% increase in occupancy for the second quarter of 2016 compared to the second quarter of 2015;

47

| · | $3.4 million increase from Recently Completed/Acquired Properties for the second quarter of 201 6 compared to the second quarter of 201 5 due to the acquisition of seven properties located in Austin, Texas during the second quarter of 2015; and

| · | $0.2 million increase from properties held for sale as of June 30, 2016.

Straight-line rents from the Total Portfolio increased by $2.5 million, of which $1.5 million relates to the Same Store Portfolio, $0.4 million relates to Recently Completed/Acquired Properties and $1.5 million relates to Development/Redevelopment Properties directly attributable to 44% of the office component of the FMC Tower that was placed into service during the second quarter of 2016. These increases were offset by a decrease of $0.7 million from the disposition of 86 properties from the second quarter of 2015 through the second quarter of 2016.

Tenant reimbursements from the Total Portfolio decreased by $3.9 million during the second quarter of 2016 compared to the second quarter of 2015 primarily attributable to a $5.8 million decrease due to the disposition of 86 properties from the second quarter of 2015 through the second quarter of 2016. This decrease was partially offset by a $1.0 million increase at the Same Store Portfolio and an increase of $1.0 million related to Recently Completed/Acquired Properties that were not part of the operating portfolio during the second quarter of 2015. Expense recoveries at the Same Store Portfolio increased modestly with a reimbursement percentage of 34.4% during the second quarter of 2016 compared to 32.9% in the second quarter of 2015.

Third party management fees, labor reimbursement and leasing increased by $1.5 million for the second quarter of 2016 compared to the second quarter of 2015, primarily due to the formation of the MAP Venture during the first quarter of 2016 and the contribution of Encino Trace to the DRA Austin Venture during the fourth quarter of 2015.

Property Operating Expenses

Property operating expenses across our Total Portfolio decreased $6.6 million for the second quarter of 2016 compared to the second quarter of 2015, of which $8.7 million of the decrease relates to the disposition of 86 properties from the second quarter of 2015 through the second quarter of 2016. This decrease was partially offset by: (i) $1.0 million increase in payroll and payroll related expenses, (ii) $0.7 million increase in repairs and maintenance expense due to the timing of tenant needs, (iii) $0.2 million increase in bad debt expense and (iv) $0.2 million increase in office expenses.

Real Estate Taxes

Real estate taxes across our Total Portfolio decreased by $0.5 million for the second quarter of 2016 compared to the second quarter of 2015, primarily attributable to a $2.0 million decrease from the disposition of 86 properties from the second quarter of 2015 through the second quarter of 2016. This increase was offset by a $1.0 million increase from Recently Completed/Acquired Properties due to the acquisition of seven properties located in Austin, Texas during the second quarter of 2015 and a $0.5 million increase is from the Same Store Property Portfolio.

Third Party Management Expenses

Third party management expenses increased by $1.0 million for the second quarter of 2016 compared to the second quarter of 2015, primarily due to the formation of the MAP Venture during the first quarter of 2016 and the contribution of Encino Trace to the DRA Austin Venture during the fourth quarter of 2015.

48

Depreciation and Amortization

Depreciation and amortization expense decreased by $4.0 million for the second quarter of 2016 compared to the second quarter of 2015, of which $10.0 million of the decrease relates to the disposition of 86 properties from the second quarter of 2015 through the second quarter of 2016 and $0.5 million relates the Same Store Property Portfolio as a result of the timing of tenant and capital improvement projects being completed and placed into service. These decreases were offset by $4.9 million in additional depreciation expense from Recently Completed/Acquired Properties and an increase in depreciation expense for the Development/Redevelopment Properties of $1.5 million.

General & Administrative Expenses

General and administrative expenses decreased by $0.7 million for the second quarter of 2016 compared to the second quarter of 2015, of which $0.4 million consists of a decrease in acquisition costs and $0.2 million consists of a decrease in corporate salaries, benefits and share-based compensation expense.

Provision for Impairment

As of June 30, 2016, a held for use impairment charge of $3.9 million was recorded on a property in our Metropolitan D.C. segment. The impairment calculation was based on our recoverability of the carrying value of the property under an undiscounted cash flow model. Also during the second quarter of 2016, in connection with the disposition of the office property at 1120 Executive Boulevard located in Mount Laurel, New Jersey, we recognized a held for sale impairment loss totaling approximately $1.8 million, which approximates the estimated loss on sale.

During the second quarter of 2015, in connection with the disposition of the office property at 100 Gateway Centre Parkway located in Richmond, Virginia, we recognized an impairment loss totaling approximately $0.8 million, which approximates the loss on sale.

Interest Expense

Interest expense decreased $8.1 million from the second quarter of 2015 to the second quarter of 2016 primarily due to the following:

| · | $3.3 million decrease related to the repayment of the mortgage debt on 2970 Market Street in Philadelphia, Pennsylvania commonly known as 30th Street Main Post Office (“Cira Square”) and on a 1,662 parking space facility located in Philadelphia, Pennsylvania commonly known as Cira South Garage (“Cira South Garage”) during 2016;

| · | $2.2 million decrease related to the repayment of the 6.00% Guaranteed Note due 2016 on April 1, 2016;

| · | $1.2 million decrease related to the repayment of the Tyson’s corner mortgage debt during 2015;

| · | $0.8 million decrease related to an increase in capitalized interest which is directly attributable to the development of the FMC Tower;

| · | $0.8 million decrease related to the refinance of Two Logan Square on April 7, 2016; and

| · | $0.3 million decrease in interest expense related to the put option of the equity interest of US Bancorp (“USB”) in Cira Square to us. The put option was exercised on September 30, 2015 and USB's interest in Cira Square was assigned to us.

The decrease of $8.6 million in interest expense described above was offset by an approximately $0.6 million increase as a result of increasing our Term Loan C balance from $200.0 million to $250.0 million subsequent to June 30, 2015.

Interest Expense – Deferred Financing Costs

Interest expense – deferred financing costs decreased $0.6 million from the second quarter of 2015 to the second quarter of 2016, primarily due to the write-off of deferred financing costs associated with the repayment of mortgage debt for Cira Square and Cira South Garage during 2016, which resulted in a $0.3 million decrease, and a $0.3 million decrease due to our entry into a new unsecured revolving credit facility on May 15, 2015.

Equity in Loss of Real Estate Ventures

The decrease in equity income from Real Estate Ventures of $0.8 million for the second quarter of 2015 compared to the second quarter of 2016 is primarily due to the following:

| · | $1.0 million of losses recognized from the MAP Venture, which was formed during the first quarter of 2016; and

49

| · | $0.5 million of operating losses recognized from the 1919 Market Street Venture, which was moved out of development and placed into service during the second quarter of 2016.

The decreases of $1.5 million were offset by increases of $0.2 million from Four Tower Bridge due to an increase in occupancy, $0.2 million from the Parc at Plymouth Meeting due to an additional four buildings being placed into service during the third and fourth quarters of 2015 and $0.3 million due to the acquisition of our remaining 50% interest in Broadmoor Austin Associates.

Net Gain (Loss) on Disposition of Real Estate

The loss on disposition of $0.8 million represents additional closing costs that were recognized at settlement on properties known as Herndon Metro Plaza I and II, located in Herndon, Virginia, during the second quarter of 2016.

The $1.6 million net gain on disposition of real estate resulted from the sale of five office properties during the second quarter of 2015 at Delaware Corporate Center I & II and Christiana Corporate Center, located in Wilmington, Delaware and Newark, Delaware, respectively.

Net Gain from Remeasurement of Investments in Real Estate Ventures

The gain of $0.8 million recognized during the second quarter of 2015 resulted from the acquisition of the remaining interest in Broadmoor Austin Associates.

Net Gain from Real Estate Venture Transactions

The gain of $3.2 million recognized during the second quarter of 2016 resulted from the disposition of the office property held by the 1000 Chesterbrook real estate venture. See Item 2., "Management’s Discussion and Analysis of Financial Condition and Results of Operations - Recent Property Transactions" above.

Net Income (loss)

Net income (loss) decreased by $4.4 million during the second quarter of 2016 compared to the second quarter of 2015 as a result of the factors described above. Net income is significantly impacted by depreciation of operating properties and amortization of acquired intangibles. These non-cash charges do not directly affect our ability to pay dividends.

Comparison of the Six-Month Periods Ended June 30, 2016 and June 30, 2015

The table below shows selected operating information for the “Same Store Property Portfolio” and the “Total Portfolio.” The Same Store Property Portfolio consists of 105 properties containing an aggregate of approximately 15.5 million net rentable square feet, and represents properties that we owned for the entire six-month periods ended June 30, 2016 and 2015. The Total Portfolio includes the effects of other properties that were either placed into service, acquired or redeveloped after January 1, 2015 and disposed of prior to June 30, 2016 or classified as held for sale as of June 30, 2016. A property is excluded from our Same Store Property Portfolio and moved into the redevelopment column in the period that we determine that a redevelopment would be the best use of the asset, and when said asset is taken out of service or is undergoing re-entitlement for a future development strategy. This table also includes a reconciliation from the Same Store Property Portfolio to the Total Portfolio net income (i.e., all properties owned by us during the six-month periods ended June 30, 2016 and 2015) by providing information for the properties which were acquired, placed into service, under development or redevelopment and administrative/elimination information for the six-month periods ended June 30, 2016 and 2015 (in thousands).

The Total Portfolio net income presented in the table is equal to the net income of the Parent Company and the Operating Partnership.

Total Revenue

Cash rents from the Total Portfolio decreased by $29.3 million during the six months ended June 30, 2016 compared to the six months ended June 30, 2015, primarily attributable to:

| · | $40.9 million decrease due to the disposition of 88 properties from the beginning of 2015 through the second quarter of 2016;

| · | $4.1 million increase in the Same Store Property Portfolio due to a 0.5% increase in occupancy for the six months ended June 30, 2016 compared to the six months ended June 30, 2015;

51

| · | $7.0 million increase from Recently Completed/Acquired Properties for the six months ended June 30, 2016 compared to the six months ended June 30, 201 5 due to the acquisition of seven properties located in Aus tin, Texas during the second quarter of 2015; and

| · | $0.3 million increase from properties held for sale as of June 30, 2016.

Straight-line rents from the Total Portfolio increased by $2.6 million, of which $1.7 million relates to the Same Store Portfolio, $0.4 million relates to Recently Completed/Acquired Properties and $1.9 million related to Development/Redevelopment Properties directly attributable to 44% of the office component of the FMC Tower that was placed into service during the second quarter of 2016. These increases were offset by a decrease of $1.2 million from the disposition of 88 properties from the beginning of 2015 through the second quarter of 2016.

Above/below-market rent amortization increased by $1.0 million, of which $2.1 million relates to the Recently Completed/Acquired Properties, partially offset by a $0.6 million decrease relating to Development/Redevelopment Properties and $0.4 million related to the Same Store Property Portfolio.

Tenant reimbursements from the Total Portfolio decreased by $6.5 million during the six months ended June 30, 2016 compared to the six months ended June 30, 2015, primarily attributable to a $10.7 million decrease due to the disposition of 88 properties from the beginning of 2015 through the second quarter of 2016. This decrease was partially offset by a $1.7 million increase at the Same Store Portfolio and an increase of $2.4 million related to Recently Completed/Acquired Properties that were not part of the operating portfolio during the second quarter of 2015. Expense recoveries at the Same Store Portfolio increased modestly with a reimbursement percentage of 35.4% during the six months ended June 30, 2016 compared to 34.1% for the six months ended June 30, 2015.

Termination fees decreased $0.6 million due to the timing of tenant terminations.

Third party management fees, labor reimbursement and leasing increased by $2.9 million for the six months ended June 30, 2016 compared to the six months ended June 30, 2015, primarily due to the formation of the MAP Venture during the first quarter of 2016 and the contribution of Encino Trace to the DRA Austin Venture during the fourth quarter of 2015.

Other income decreased by $2.5 million during the six-month period ended June 30, 2016, which is primarily attributed to $1.1 million in property tax settlements, $0.6 million in liquidating distributions from an unconsolidated partnership investment and $0.2 million in escheatment funds received during the six months ended June 30, 2015, with no such income in 2016. The additional $0.6 million decrease relates to other income across our portfolio.

Property Operating Expenses

Property operating expenses across our Total Portfolio decreased $12.3 million for the six months ended June 30, 2016 compared to the six months ended June 30, 2015, of which $16.1 million of the decrease relates to the disposition of 88 properties from the beginning of 2015 through the second quarter of 2016 and $0.6 million relates to a reduction in utilities expense. These decreases were partially offset by: (i) $2.3 million increase in repairs and maintenance expense due to the timing of tenant needs, (ii) $1.2 million increase in payroll and payroll related expenses and (iii) $0.8 million increase in office expenses.

Real Estate Taxes

Real estate taxes across our Total Portfolio decreased by $1.1 million for the six months ended June 30, 2016 compared to the six months ended June 30 2015, primarily attributable to a $3.9 million decrease from the disposition of 88 properties from the beginning of 2015 through the second quarter of 2016. This increase was offset by a $2.2 million increase from Recently Completed/Acquired Properties and a $0.5 million increase from the Same Store Property Portfolio.

Third Party Management Expenses

Third party management expenses increased by $1.4 million for the six months ended June 30, 2016 compared to the six months ended June 30, 2015, primarily due to the formation of the MAP Venture during the first quarter of 2016 and the contribution of Encino Trace to the DRA Austin Venture during the fourth quarter of 2015.

Depreciation and Amortization

Depreciation and amortization expense decreased by $6.3 million for the six months ended June 30, 2016 compared to the six months ended June 30, 2015 primarily relating to a $21.1 million decrease from the disposition of 88 properties from the beginning of 2015

52

through the second quarter of 2016 and $0.6 million related to a re-entitlement property placed into land inventory during 2016 that was being depreciated during 2015. These decreases were offset by $12.1 million in additional depreciation expense from Recently Completed/Acquired Prop erties, $2.7 million from Development/Redevelopment Properties and an increase in depreciation expense at the Same Store Property Portfolio of $0.6 million, as a result of the timing of tenant and capital improvement projects being completed and placed int o service.

General & Administrative Expenses

General and administrative expenses decreased by $0.2 million for the second quarter of 2016 compared to the second quarter of 2015, primarily due to a $0.5 million decrease in corporate salaries, benefits and share-based compensation expense. These decreases were offset by $0.4 million of additional acquisition deal costs.

Provision for Impairment

During the six-month period ended June 30, 2016, we recognized a $13.1 million provision for impairment. During the first quarter of 2016, we recognized a held for use impairment loss totaling $7.4 million. This impairment charge resulted from our held for use impairment analysis, which determined that we would not recover the carrying value of two properties located in our Metropolitan D.C. segment. As of June 30, 2016, a held for use impairment charge of $3.9 million was recorded on a property in our Metropolitan D.C. segment. The impairment calculation was based on our recoverability of the carrying value of the property under an undiscounted cash flow model. Also during the second quarter of 2016, in connection with the disposition of the office property at 1120 Executive Boulevard located in Mount Laurel, New Jersey, we recognized a held for sale impairment loss totaling approximately $1.8 million, which approximates the estimated loss on sale.

As of March 31, 2015, the carrying value of the Lake Merritt office property exceeded the fair value less the costs of sale and, as a result, we recognized an impairment loss totaling approximately $1.7 million during the first quarter of 2015. During the second quarter of 2015, in connection with the disposition of the office property at 100 Gateway Centre Parkway located in Richmond, Virginia, we recognized an impairment loss totaling approximately $0.8 million, which approximates the loss on sale.

Interest Expense

Interest expense decreased $12.6 million from the six-month period ended June 30, 2015 to the six-month period ended June 30, 2016 primarily due to the following:

| · | $6.1 million decrease related to the repayment of the mortgage debt on Cira Square and on a 1,662 parking space facility located in Philadelphia, Pennsylvania commonly known as Cira South Garage during 2016;

| · | $1.8 million related to an increase in capitalized interest which is directly attributable to the development of the FMC Tower;

| · | $0.6 million decrease in interest expense related to the put option of the equity interest of US Bancorp (“USB”) in Cira Square to us. The put option was exercised on September 30, 2015 and USB's interest in Cira Square was assigned to us;

| · | $2.2 million decrease related to the repayment of the 6.00% Guaranteed Note due 2016 on April 1, 2016;

| · | $2.3 million decrease related to the repayment of the Tyson’s corner mortgage debt during 2015; and

| · | $0.8 million decrease related to the refinance of Two Logan Square on April 7, 2016.

The decrease of $13.8 million in interest expense described above was offset by a $1.1 million increase as a result of an increase in the balance of our Term Loan C from $200.0 million to $250.0 million subsequent to June 30, 2015. Additionally, interest expense increased by approximately $0.1 million under our unsecured revolving credit facility, which we used to fund repayment of the mortgage debt on Cira Square and Cira South Garage in Philadelphia. We used the proceeds from the sale of Och-Ziff transaction to repay the entire balance of our unsecured revolving credit facility prior to March 31, 2016.

53

Interest Expense – Deferred Financing Costs

Interest expense – deferred financing costs decreased $0.9 million for the six-month period ended June 30, 2016 compared to the six-month period ended June 30, 2015, primarily due to the write-off of deferred financing costs associated with the repayment of mortgage debt for Cira Square and Cira South Garage during 2016, which resulted in a $0.5 million decrease, and a $0.4 million decrease due to our entry into a new unsecured revolving credit facility on May 15, 2015.

Equity in Loss of Real Estate Ventures

The decrease in equity income from Real Estate Ventures of $1.3 million for the six-month period ended June 30, 2016 compared to the six-month period ended June 30, 2015 is primarily due to the following:

| · | $1.6 million of operating losses recognized from the MAP Venture, which was formed during the first quarter of 2016;

| · | $0.5 million of operating losses recognized from the 1919 Market Venture, which was moved out of development and placed into service during the second quarter of 2016; and

| · | $0.6 million of operating losses recognized from the Austin DRA Venture due to an early termination of a tenant’s lease during the first quarter of 2016.

The decreases of $2.7 million were offset by increases of $0.9 million from evo at Cira Centre South as a result of an increase in our ownership interest in the venture from 30% to 50% during 2016 as well as increased rental rates and $0.5 million from the Parc at Plymouth Meeting due to an additional four buildings being placed into service during the third and fourth quarters of 2015.

Net Gain on Disposition of Real Estate

The $115.5 million net gain on disposition of real estate recognized for the six-month period ended June 30, 2016 resulted from the sale in February 2016 of an office property known as Cira Square, located in Philadelphia, Pennsylvania, consisting of 862,692 square feet. The sale of the MAP Venture properties in February 2016 did not have a material impact on the gain on sale because of an impairment charge of $45.4 million recorded during the fourth quarter of 2015. During the first quarter of 2016, we recognized an impairment loss totaling approximately $7.4 million on the properties known as Metro Plaza I & II located in Herndon, Virginia. The loss on disposition of $0.8 million represents additional closing costs that were recognized at settlement during the second quarter of 2016.

The $10.6 million net gain on disposition recognized during the six months ended June 30, 2015 relates to the sale of nine office properties.

Net Gain from Remeasurement of Investments in Real Estate Ventures

The gain of $0.8 million recognized during the six months ended June 30, 2015 resulted from the acquisition of the remaining interest in Broadmoor Austin Associates.

Net Gain Real Estate Venture Transactions

The gain of $5.9 million recognized during the first quarter of 2016 resulted of the sale of our entire 50% interest in the Coppell Associates real estate venture. The gain of $3.2 million recognized during the second quarter of 2016 resulted from the disposition of the office property held by the 1000 Chesterbrook real estate venture. See Item 2., "Management’s Discussion and Analysis of Financial Condition and Results of Operations - Recent Property Transactions" above.

Loss on Early Extinguishment of Debt

On January 14, 2016, we used borrowings from our $600.0 million unsecured revolving credit facility to fund the repayment of our $176.9 million mortgage and our $35.5 million mortgage which encumbered Cira Square and Cira South Garage, respectively. Each mortgage was repaid ahead of its scheduled maturity date of September 10, 2030, which resulted in prepayment penalties and non-cash charges for the write-off of deferred financing costs totaling $66.6 million. We subsequently repaid in full the advances under our unsecured revolving credit facility with the proceeds from the dispositions of real estate that occurred during the six months ended June 30, 2016. There were no comparable extinguishments of debt incurred during the six months ended June 30, 2015.

54

Net Income

Net income increased by $33.3 million during the six months ended June 30, 2016 compared to the six months ended June 30, 2015 as a result of the factors described above. Net income is significantly impacted by depreciation of operating properties and amortization of acquired intangibles. These non-cash charges do not directly affect our ability to pay dividends.

LIQUIDITY AND CAPITAL RESOURCES

General

Our principal liquidity needs for the next twelve months are as follows:

| · | fund normal recurring expenses,

| · | fund capital expenditures, including capital and tenant improvements and leasing costs,

| · | fund repayment of certain debt instruments when they mature,

| · | fund current development and redevelopment costs,

| · | fund commitments to unconsolidated real estate ventures,

| · | fund distributions to shareholders to maintain REIT status, and

| · | fund share repurchases.

As of June 30, 2016, the Parent Company owned a 99.1% interest in the Operating Partnership. The remaining interest of approximately 0.9% pertains to common limited partnership interests owned by non-affiliated investors who contributed property to the Operating Partnership in exchange for their interests. As the sole general partner of the Operating Partnership, the Parent Company has full and complete responsibility for the Operating Partnership’s day-to-day operations and management. The Parent Company’s source of funding for its dividend payments and other obligations is the distributions it receives from the Operating Partnership.

We believe that our liquidity needs will be satisfied through available cash balances and cash flows generated by operations, financing activities and selective property sales. Rental revenue, expense recoveries from tenants, and other income from operations are our principal sources of cash to pay operating expenses, debt service, recurring capital expenditures and the minimum distributions required to maintain our REIT qualification. We seek to increase cash flows from our properties by maintaining quality standards for our properties that promote high occupancy rates and permit increases in rental rates while reducing tenant turnover and controlling operating expenses. Our revenue also includes third-party fees generated by our property management, leasing, development and construction businesses. We believe that our revenue, together with proceeds from property sales and debt financings, will continue to provide funds for our short-term liquidity needs. However, material changes in our operating or financing activities may adversely affect our net cash flows. With uncertain economic conditions, vacancy rates may increase, effective rental rates on new and renewed leases may decrease and tenant installation costs, including concessions, may increase in most or all of our markets throughout the remainder of 2016 and possibly beyond. As a result, our revenues and cash flows could be insufficient to cover operating expenses, including increased tenant installation costs, pay debt service or make distributions to shareholders over the short-term. If this situation were to occur, we expect that we would finance cash deficits through borrowings under our unsecured credit facility and other sources of debt and equity financings. In addition, a material adverse change in cash provided by operations could adversely affect our compliance with financial performance covenants under our unsecured credit facility, including unsecured term loans and unsecured notes. As of June 30, 2016, we were in compliance with all of our debt covenants and requirement obligations.

We use multiple financing sources to fund our long-term capital needs. When needed, we use borrowings under our unsecured credit facility for general business purposes, including to meet debt maturities and to fund distributions to shareholders as well as development and acquisition costs and other expenses from time to time as necessary. In light of the continuing volatility in financial markets and economic uncertainties, it is possible, that one or more lenders under our unsecured revolving credit facility could fail to fund a borrowing request. Such an event could adversely affect our ability to access funds from our unsecured credit facility when needed to fund distributions or pay expenses.

Our ability to incur additional debt is dependent upon a number of factors, including our credit ratings, the value of our unencumbered assets, our degree of leverage and borrowing restrictions imposed by our lenders. If one or more rating agencies were to downgrade our unsecured credit rating, our access to the unsecured debt market would be more limited and the interest rate under our unsecured credit facility and unsecured term loans would increase.

The Parent Company unconditionally guarantees the Operating Partnership’s secured and unsecured obligations, which, as of June 30, 2016, amounted to $348.1 million and $1,703.6 million, respectively.

55

We maintain a shelf registration statement that has registered the offering and sale of common shares, preferred shares, depositary shares, warrants and unsecured debt securities. Subject to our ongoing compliance with securities laws, and if warranted by market conditions, we may offer and sell equity and debt securities from time to time under the shelf registration statement. We also maintain a continuous offering program under which we may sell up to 16,000,000 common shares until November 5, 2016 in at-the-market offerings.

The Parent Company maintains a share repurchase program under which the Board of Trustees has authorized the Parent Company to repurchase shares of its preferred and common stock with no expiration date. On July 22, 2015, the Parent Company's Board of Trustees authorized additional share repurchases of up to $100.0 million. Prior to the authorization 539,200 common shares were available for repurchase under the preexisting share repurchase program. We expect to fund the share repurchases with a combination of available cash balances and availability under our unsecured revolving credit facility. As of June 30, 2016, 4,701,302 common shares have been repurchased and retired at an average purchase price of $12.92 per share and totaling $60.8 million. The timing and amounts of any purchases will depend on a variety of factors, including market conditions, regulatory requirements, share prices, capital availability and other factors as determined by our management team. The repurchase program does not require the purchase of any minimum number of shares and may be suspended or discontinued at any time without notice. No shares were repurchased during the six-month period ended June 30, 2016.

The Parent Company, other than acting as the sole general partner of the Operating Partnership, also issues equity from time to time, the proceeds of which it contributes to the Operating Partnership in exchange for additional interests in the Operating Partnership, and guarantees debt obligations of the Operating Partnership. The Parent Company’s ability to sell common shares and preferred shares is dependent on, among other things, general market conditions for REITs, market perceptions about the Company as a whole and the current trading price of the Parent Company’s shares.

The Operating Partnership also considers net sales of selected properties as another source of managing its liquidity. During 2016, we sold 61 properties, of which 58 were contributed to an unconsolidated real estate venture, containing 4,984,700 in net rentable square feet and 120 acres of land for an aggregate sales price of $797.5 million.

On January 14, 2016, we funded $265.8 million to prepay two mortgage loans, consisting of $176.9 million of principal repayment, $44.5 million in prepayment charges and a nominal amount of accrued interest. These mortgages were secured by our interests in Cira Square in Philadelphia. Also on January 14, 2016, we funded $44.4 million to prepay an additional mortgage loan, consisting of $35.5 million of principal repayment, $8.9 million in prepayment charges and a nominal amount of accrued interest. This mortgage was secured by our interest in the Cira South Garage. All three of the foregoing mortgages had a scheduled maturity date of September 10, 2030. We funded the repayments with funds available under our $600.0 million unsecured revolving credit facility. Subsequent to repayments of the mortgages indebtedness, we closed on the disposition of Cira Square and completed the Och-Ziff transaction, receiving total net proceeds of $350.1 million and $354.0 million, respectively. We used a portion of these funds to repay the $195.0 million balance then outstanding under our revolving credit facility with the remaining balance funded through available cash balances. We intend to use the remainder of the net cash proceeds from the disposition of Cira Square and the Och-Ziff transactions for general corporate purposes, including to reduce our outstanding debt and fund our current development commitments.

On April 1, 2016, we used available cash balances to repay the entire $149.9 million principal balance of our 6.00% Guaranteed Unsecured Notes due 2016 upon their maturity.

On April 7, 2016, the Company closed on an $86.9 million first mortgage financing on Two Logan Square, a 708,844-square foot office property located in Philadelphia, Pennsylvania. Proceeds of the loan were used to repay, without penalty, the $86.6 million principal balance of the former Two Logan Square first mortgage loan, which had a 7.57% effective interest rate.

We continue to maintain substantial liquidity, and as of July 22, 2016, we had available cash of approximately $225.7 million and $585.7 million of availability, net of $14.3 million of outstanding letters of credit, under our unsecured revolving credit facility.

56

Cash Flows

The following discussion of our cash flows is based on the consolidated statement of cash flows and is not meant to be a comprehensive discussion of the changes in our cash flows for the periods presented.

As of June 30, 2016 and December 31, 2015, we maintained cash and cash equivalents of $265.6 million and $56.7 million, respectively. The following are the changes in cash flow from our activities for the six-month periods ended June 30, 2016 and 2015 (in thousands):

Activity |  | 2016 |  |  | 2015 |
Operating |  | $ | 29,068 |  |  | $ | 88,617 |
Investing |  |  | 600,285 |  |  |  | (155,370 | )
Financing |  |  | (420,450 | ) |  |  | (66,767 | )
Net cash flows |  | $ | 208,903 |  |  | $ | (133,520 | )

Our principal source of cash flows is from the operation of our properties. Our properties provide a relatively consistent stream of cash flows that provides us with the resources to fund operating expenses, debt service and quarterly dividends. We do not restate our cash flows for discontinued operations.

The net decrease of $59.5 million in cash from operating activities for the six months ended June 30, 2016 compared to the six months ended June 30, 2015 is primarily attributable to the following:

| · | $53.4 million decrease from prepayment penalties resulting from the repayment of the mortgage loans secured by Cira Square and Cira South Garage ahead of their scheduled maturity;

| · | the disposition of 88 properties from the beginning of 2015 through the second quarter of 2016; and

| · | the timing of cash receipts and cash expenditures in the normal course of operations.

The net increase of $755.7 million in cash provided by investing activities during the six months ended June 30, 2016 to the six months ended June 30, 2015 is primarily attributable to the following:

| · | $605.3 million of net proceeds from the disposition of 61 office properties and a land parcel during the six months ended June 30, 2016 (see Item 2., "Management’s Discussion and Analysis of Financial Condition and Results of Operations - Recent Property Transactions" above) compared to the sale of nine office properties during the six months ended June 30, 2015;

| · | $183.2 million for the acquisition of the remaining 50% common interest in the Broadmoor Austin Associates real estate venture containing seven office properties in Austin, Texas, a land parcel in Washington, D.C. and a leasehold interest in a land parcel in Austin, Texas during the six months ended June 30, 2015, with no comparable acquisitions during 2016;

| · | $33.8 million decrease of investments in unconsolidated Real Estate Ventures primarily due to contributions for the six months ended June 30, 2016 of $12.8 million to the evo at Cira Centre South Venture to increase our ownership interest from 30% to 50% (see Item 2., "Management’s Discussion and Analysis of Financial Condition and Results of Operations – Recent Property Transactions" above for further disclosure), $2.3 million in contributions to the J BG real estate ventures and $0.2 million to the Seven Tower Bridge Venture in 2016 compared to the contribution of $28.4 million to form the JBG real estate ventures, $7.9 million in contributions to fund the construction of the subterranean garage at the 4040 Wilson real estate venture, $6.8 million to fund the construction of Brandywine 1919 Ventures, $3.4 million to the DRA Austin real estate venture and $2.6 million in contributions to other real estate ventures in 2015;

| · | $5.7 million decrease in capital expenditures for tenant improvements, developments/redevelopments and leasing commissions.

| · | $4.8 million from the sale of our interests in an unconsolidated real estate venture during the six-month period ended June 30, 2016, with no comparable sales during the six-month period ended June 30, 2015;

| · | $2.0 million increase in deposits;

| · | $4.9 million increase in escrow cash due to timing of payments; and

| · | $4.5 million increase in cash distributions in excess of cumulative equity in income from Real Estate Ventures.

57

The increase in cash provided by investing activities was offset by the following transactions:

| · | $88.0 million decrease in payments on the mortgage note receivable due to the repayment of the short term loan to the Austin Venture during the first quarter of 2015; and

| · | $0.6 million decrease in advances made for purchase of tenant assets, net of repayments.

The net increase of $353.7 million in cash used in financing activities for the six months ended June 30, 2016 compared to the six months ended June 30, 2015 is attributable to the following:

| · | $207.4 million net increase from the repayments of mortgage notes payable during the six-month period ended June 30, 2016 compared to the six-month period ended June 30, 2015, primarily due to the early repayment of $212.4 million of mortgage notes payable for Cira Square and Cira South Garage;

| · | $149.9 million from the repayment of the 2016 6.00% Guaranteed Unsecured Notes upon maturity on April 1, 2016; and

| · | $1.0 million decrease in partner contributions to a consolidated real estate venture that was formed during the second quarter of 2015.

The increase in cash used in financing activities was offset by the following transactions:

| · | $2.5 million decrease in debt financing costs paid, of which the additional prior year costs primarily relate to the revolving credit facility entered into May 15, 2015;

| · | $1.4 million decrease in distributions paid to shareholders and on non-controlling interests due to the repurchase of 5,209,437 common shares during the second half of 2015; and

| · | $0.7 million increase in proceeds from the exercise of stock options.

The indenture under which the Operating Partnership issued its unsecured notes contains financial covenants, including (i) a leverage ratio not to exceed 60%, (ii) a secured debt leverage ratio not to exceed 40%, (iii) a debt service coverage ratio of greater than 1.5 to 1.0 and (iv) an unencumbered asset value of not less than 150% of unsecured debt. The Operating Partnership is in compliance with all covenants as of June 30, 2016.

The Operating Partnership has mortgage loans that are collateralized by certain of its properties. Payments on mortgage loans are generally due in monthly installments of principal and interest, or interest only. The Operating Partnership intends to refinance or repay its mortgage loans as they mature through the use of proceeds from selective property sales and secured or unsecured borrowings. However, in the current and expected future economic environment one or more of these sources may not be available on attractive terms or at all.

On April 7, 2016, we closed on an $86.9 million first mortgage financing on Two Logan Square, a 708,844-square foot office property located in Philadelphia, Pennsylvania. The loan bears interest at 3.98% per annum and matures on May 1, 2020. Proceeds of the loan were used to repay, without penalty, the $86.6 million principal balance of the former Two Logan Square first mortgage loan, which had a 7.57% effective interest rate.

On April 1, 2016, we repaid the entire $149.9 million principal balance of its 2016 6.00% Guaranteed Unsecured Notes upon maturity, which had a 5.95% effective interest rate.

On January 14, 2016, we funded $265.8 million to prepay two mortgage loans, consisting of $176.9 million of principal repayment, $44.5 million in prepayment charges and a nominal amount of accrued interest, in repayment of the mortgage indebtedness of the office property located at 2970 Market Street in Philadelphia, Pennsylvania commonly known as 30th Street Main Post Office, ahead of its scheduled maturity date of September 10, 2030. Also on January 14, 2016, we funded $44.4 million, consisting of $35.5 million of principal repayment, $8.9 million in prepayment charges and a nominal amount of accrued interest, in repayment of the mortgage indebtedness of a 1,662 parking space facility located in Philadelphia, Pennsylvania commonly known as Cira South Garage, ahead of its scheduled maturity date of September 10, 2030. These repayments were financed with $195.0 million of funds available under the unsecured revolving credit facility. Additionally, we recognized a $13.2 million loss on extinguishment of debt, consisting of $10.8 million and $2.4 million related to non-cash charges for deferred financing costs for Cira Square and Cira South Garage, respectively.

Equity

On May 24, 2016, the Parent Company declared a distribution of $0.16 per common share, totaling $28.2 million, which it paid on July 20, 2016 to its shareholders of record as of July 6, 2016. In addition, the Parent Company declared a distribution on its Series E Preferred Shares to holders of record as of June 30, 2016. These shares are entitled to a preferential return of 6.90% per annum on the $25.00 per share liquidation preference. Distributions paid on July 15, 2016 to holders of Series E Preferred Shares totaled $1.7 million. To fund these distributions, on May 24, 2016, the Operating Partnership declared a distribution of $0.16 per common partnership unit, totaling $28.2 million, which was paid on July 20, 2016 to unitholders of record as of July 6, 2016. In addition, the Operating Partnership declared distributions on its Series E-Linked Preferred Mirror Units to holders of record as of June 30, 2016. These units are entitled to

59

a preferential return of 6.90% per annum on the $25.00 per unit liquidation preference. Distributions paid on July 15, 2016 to holders of Series E-Linked Preferred Mirror Units totaled $1.7 million. In order to maintain its qualification as a REIT, the Parent Company is required to, among other things, pay dividends to its shareholders of at least 90% of its REIT taxable income.

Inflation

A majority of our leases provide for tenant reimbursement of real estate taxes and operating expenses either on a triple net basis or over a base amount. In addition, many of our office leases provide for fixed base rent increases. We believe that inflationary increases in expenses will be partially offset by expense reimbursement and contractual rent increases.

Contractual Obligations

The following table outlines the timing of payment requirements related to our contractual obligations as of June 30, 2016:

On April 1, 2016, we repaid the entire principal balance of our $149.9 million 2016 6.00% Guaranteed Unsecured Notes. See Note 6, “Debt Obligations,” to our consolidated financial statements.

(b) | Future minimum rental payments under the terms of all non-cancelable ground leases under which we are the lessee are expensed on a straight-line basis regardless of when payments are due. The table also does not include the future minimum rental payments related to two ground leases in Philadelphia, Pennsylvania.

(c) | Represents contractual obligations for wholly owned development projects and does not contemplate all costs expected to be incurred for such developments. This table does not include contractual obligations for our real estate venture developments, which are described below.

(d) | Variable rate debt future interest expense commitments are calculated using June 30, 2016 interest rates.

(e) | Other liabilities consists of (i) our deferred compensation liability, (ii) the interest accretion on the existing transfer tax liability on Two Logan Square in Philadelphia, Pennsylvania and (iii) the contingent consideration associated with the purchase of 618 Market Street in Philadelphia, Pennsylvania and (iv) the deferred payment associated with the purchase of 2100 Market Street in Philadelphia, Pennsylvania.

The above table does not include amounts related to the JBG Ventures at 51 N 50 Patterson and 1250 First Street in Washington, D.C. or the 1919 Ventures development of the property located at 20th and Market Street in Philadelphia, Pennsylvania. For further discussion of real estate venture developments, see Item 1., “Business – Developments,” included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 and Item 2., “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Overview – Development Risk,” for further details.

We provide customary guarantees for certain development projects of our unconsolidated real estate ventures. See Note 4, "Investment in Unconsolidated Ventures," to the consolidated financial statements for further details on payment guarantees provided on the behalf of real estate ventures.

In addition, the above table does not include amounts related to the Schuylkill Yards Project. See Item 2., “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Overview – Development Risk," for further details.

As of December 31, 2015, we provided a cost overrun guarantee on the Subaru Headquarters Development (See Note 13, "Commitments and Contingencies") for amounts in excess of the NTE amount. The NTE amount, currently at $77.3 million, may be adjusted by change orders agreed upon by both Subaru and us. We are obligated to pay for construction costs in excess of the NTE amount. The terms of the

60

guarantee do not provide a limitation on the costs we may be responsible for. The above table does not include any costs related to this cost overrun guarantee.

As of June 30, 2016, we were obligated to pay a maximum of $57.8 million for tenant improvements not yet completed, which is not included in the above table. We expect that most of the obligations will be paid within one year.

Put Option

On May 4, 2015, we entered into a put agreement in the ordinary course of business that grants an independent third party the unilateral option to require us to purchase a property, at a predetermined price, until May 4, 2018. In addition to the $35.0 million purchase price, we would be responsible for transaction and closing costs. There can be no assurance that the counterparty will exercise the option.

Funds from Operations (FFO)

Pursuant to the revised definition of FFO adopted by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”), we calculate FFO by adjusting net income/(loss) attributable to common unit holders (computed in accordance with GAAP) for gains (or losses) from sales of properties, impairment losses on depreciable consolidated real estate, impairment losses on investments in unconsolidated joint ventures driven by a measurable decrease in the fair value of depreciable real estate held by the unconsolidated Real Estate Ventures, real estate related depreciation and amortization, and after similar adjustments for unconsolidated Real Estate Ventures. FFO is a non-GAAP financial measure. We believe that the use of FFO combined with the required U.S. GAAP presentations, has been beneficial in improving the understanding of operating results of REITs among the investing public and making comparisons of REITs’ operating results more meaningful. We consider FFO to be a useful measure for reviewing comparative operating and financial performance because, by excluding gains or losses related to sales of previously depreciated operating real estate assets and real estate depreciation and amortization, FFO can help the investing public compare the operating performance of a company’s real estate between periods or as compared to other companies. Our computation of FFO may not be comparable to FFO reported by other REITs or real estate companies that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently.

We consider net income, as defined by U.S. GAAP, to be the most comparable earnings measure to FFO. While FFO and FFO per unit are relevant and widely used measures of operating performance of REITs, FFO does not represent cash flow from operations or net income as defined by U.S. GAAP and should not be considered as alternatives to those measures in evaluating our liquidity or operating performance. We believe that to further understand our performance, FFO should be compared with our reported net income/(loss) attributable to common unit holders and considered in addition to cash flows in accordance with GAAP, as presented in our consolidated financial statements.

61

The following table presents a reconciliation of net income attributable to common unit holders to FFO for the three- and six-month periods ended June 30, 2016 and 2015:

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Market risk is the exposure to loss resulting from changes in interest rates, commodity prices and equity prices. In pursuing our business plan, the primary market risk to which we are exposed is interest rate risk. Changes in the general level of interest rates prevailing in the financial markets may affect the spread between our yield on invested assets and cost of funds and, in turn, our ability to make distributions or payments to our shareholders. While we have not experienced any significant credit losses, in the event of a significant rising interest rate environment and/or continued economic slowdown, defaults could increase and result in losses to us which would adversely affect our operating results and liquidity.

Interest Rate Risk and Sensitivity Analysis

The analysis below presents the sensitivity of the market value of the Operating Partnership’s financial instruments to selected changes in market rates. The range of changes chosen reflects its view of changes which are reasonably possible over a one-year period. Market values are the present value of projected future cash flows based on the market rates chosen.

Our financial instruments consist of both fixed and variable rate debt. As of June 30, 2016, our consolidated debt consisted of mortgage loans with an outstanding principal balance of $348.1 million and unsecured notes with an outstanding principal balance of $1,375.0 million, all of which are fixed rate borrowings. We also have variable rate debt consisting of trust preferred securities with an outstanding principal balance of $78.6 million and an unsecured term loan with an outstanding principal balance of $250.0 million, all of which have been swapped to fixed rates. All financial instruments were entered into for other than trading purposes and the net market value of these financial instruments is referred to as the net financial position. Changes in interest rates have different impacts on the fixed and variable rate portions of our debt portfolio. A change in interest rates on the fixed portion of the debt portfolio impacts the net

62

financial instrument position, but has no impact on interest incurred or cash flows. A change in i nterest rates on the variable portion of the debt portfolio impacts the interest incurred and cash flows, but does not impact the net financial instrument position.

If market rates of interest increase by 100 basis points, the fair value of our outstanding fixed-rate mortgage debt would decrease by approximately $16.5 million. If market rates of interest decrease by 100 basis points, the fair value of our outstanding fixed-rate mortgage debt would increase by approximately $17.5 million.

As of June 30, 2016, based on prevailing interest rates and credit spreads, the fair value of our unsecured notes was $1,413.4 million. For sensitivity purposes, a 100 basis point change in the discount rate equates to a change in the total fair value of our unsecured notes of approximately $14.0 million at June 30, 2016.

From time to time or as the need arises, we use derivative instruments to manage interest rate risk exposures and not for speculative or trading purposes. The total outstanding principal balance of our variable rate debt was approximately $328.6 million at June 30, 2016. The total fair value of our debt was approximately $305.4 million at June 30, 2016. For sensitivity purposes, if market rates of interest increase by 100 basis points the fair value of our variable rate debt would decrease by approximately $21.9 million at June 30, 2016. If market rates of interest decrease by 100 basis points the fair value of our outstanding variable rate debt would increase by approximately $24.3 million.

These amounts were determined solely by considering the impact of hypothetical interest rates on our financial instruments. Due to the uncertainty of specific actions we may undertake to minimize possible effects of market interest rate increases, this analysis assumes no changes in our financial structure.

Part II. OTHER INFORMATION

Item 1. Legal Proceedings

None.

Item 1A. Risk Factors

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the following risk factor as well as the other factors discussed in Part I, Item 1A. Risk Factors in our 2015 Annual Report.

Our development projects are dependent on strategic alliances with unaffiliated third parties

The challenge of managing our strategic alliances is rising. As our development projects become more complex, the need for trust, collaboration, and equitable risk-sharing is essential to the success of these projects. The alliances we engage in are driven by the complementary skills and capabilities of our partners. Despite the diligence performed establishing these alliances, our objectives may not completely align with those of our partners throughout the development project or projects. Disagreements with one or more third parties with whom we partner in the development of one or more of the development components may restrict our ability to act exclusively in our own interests. In addition, failure of one or more third parties with whom we partner to fulfill obligations to us could result in delays and increased costs to us associated with finding a suitable replacement partner. Increased costs could require us to revise or abandon our activities entirely with respect to one or more components of the project and, in such event, we would not recover, and would be required to write-off, costs we had capitalized in development.

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

(a) | None.

(b) | Not applicable.

(b) | There were no common share repurchases under the Parent Company’s share repurchase program, or other repurchases of equity securities of the Parent Company or the Operating Partnership, during the fiscal quarter ended June 30, 2016. As of June 30, 2016, $32.7 million remained available for repurchases under our share repurchase program.

Item 3. Defaults Upon Senior Securities

None.
