EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended September 30, 2018 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 September 30, 2018, owned a 99.2% interest in the Operating Partnership. The remaining 0.8% 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, this report pre sents 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.

1. ORGANIZATION OF THE PARENT COMPANY AND 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 September 30, 2018, owned a 99.2% 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 September 30, 2018, the Company owned 93 properties that contain an aggregate of approximately 16.5 million net rentable square feet (collectively, the “Properties”). The Company’s core portfolio of operating properties, as of September 30, 2018, excludes two development properties and five redevelopment properties under construction or committed for construction (collectively, the “Core Properties”). The Properties were comprised of the following as of September 30, 2018:

|  |  | Number of Properties |  |  | Rentable Square Feet |
Office properties |  |  |  | 73 |  |  |  | 13,673,405 |
Mixed-use properties |  |  |  | 4 |  |  |  | 646,741 |
Retail properties |  |  |  | 1 |  |  |  | 17,884 |
Core Properties |  |  |  | 78 |  |  |  | 14,338,030 |
Development properties |  |  |  | 2 |  |  |  | 247,818 |
Redevelopment properties |  |  |  | 5 |  |  |  | 583,719 |
Held for sale properties (a) |  |  |  | 8 |  |  |  | 1,293,197 |
The Properties |  |  |  | 93 |  |  |  | 16,462,764 |

In addition to the Properties, as of September 30, 2018, the Company owned land held for development, comprised of 234 acres of undeveloped land, of which 37.9 acres were held for sale, 1.8 acres related to leasehold interests in two land parcels, each acquired through prepaid 99-year ground leases, and held options to purchase approximately 55.5 additional acres of undeveloped land. As of September 30, 2018, the total potential development that these land parcels could support under current zoning and entitlements, including the parcels under option, amounted to an estimated 14.2 million square feet, of which 0.4 million square feet relates to 37.9 acres held for sale. As of September 30, 2018, the Company also owned interests in unconsolidated real estate ventures (see Note 4, “Investment in Unconsolidated Real Estate Ventures,” for further information). 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; Wilmington, Delaware and Austin, Texas.

The Company conducts its third-party real estate management services business primarily through wholly-owned management company subsidiaries. As of September 30, 2018, the management company subsidiaries were managing properties containing an aggregate of approximately 25.3 million net rentable square feet, of which approximately 16.5 million net rentable square feet related to Properties owned by the Company and approximately 8.8 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 consist solely of normal recurring matters, and result in a fair statement of the financial position of the Company as of September 30, 2018, the results of its operations for the three- and nine-month periods ended September 30, 2018 and 2017 and its cash flows for the nine-month periods ended September 30, 2018 and 2017 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

19

Company’s and the Operating Partnership’s consolidated financial statements and footnotes included in their combined 2017 Annual Report on Form 10-K filed with the SEC on February 23, 2018.

The Company's Annual Report on Form 10-K for the year ended December 31, 2017 contains a discussion of our significant accounting policies under Note 2, "Summary of Significant Accounting Policies". Other than the adoption of ASU 2014-09, Revenue from Contracts with Customers (Topic 606), and ASU 2016-18, Statement of Cash Flows: Restricted Cash (Topic 230), there have been no significant changes in our significant accounting policies since December 31, 2017. Management discusses our significant accounting policies and management’s judgments and estimates with the Company's Audit Committee.

Out of Period Adjustment

The Company recorded $1.2 million of impairment charges during the quarter ended December 31, 2016, which should have been recorded in the consolidated financial statements for the nine-month period ended September 30, 2017 and the year ended December 31, 2017. Management concluded that these misstatements were not material to any prior period, nor were they material to the consolidated financial statements as of and for the twelve-month periods ended December 31, 2017 and 2016.

Reclassifications and Adoption of New Accounting Guidance

Through the three- and nine-month periods ended September 30, 2017, the Company included $0.8 million and $1.0 million of income tax benefit in general and administrative expenses, respectively. During the fourth quarter of 2017, the Company began disaggregating our income tax provision/benefit in the consolidated statements of operations. As a result, in the statements of operations for the three- and nine-month periods ended September 30, 2017, included herein, the Company reclassified $0.8 million and $1.0 million of net income tax benefit out of general and administrative expenses into the “Income tax (provision) benefit” caption in the consolidated statements of operations to provide comparative presentation.

During the first quarter of 2018, the Company adopted Financial Accounting Standards Board (the “FASB”) ASU No. 2016-18, which requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts described as restricted cash or cash equivalents. Beginning-of-period and end-of-period total amounts shown on the statement of cash flows should include restricted cash, cash equivalents and amounts described as restricted cash or cash equivalents. The guidance does not define restricted cash or restricted cash equivalents. As of September 30, 2018 and September 30, 2017, the Company had $0.8 million and $1.3 million of restricted cash, respectively, on its consolidated balance sheets within the caption ‘Other assets.’ As a result of the adoption of this ASU, restricted cash balances are included with cash and cash equivalents balances as of the beginning and end of each period presented in the consolidated statements of cash flows. Separate line items reconciling changes in restricted cash balances to the changes in cash and cash equivalents will no longer be presented within the operating and investing sections of the consolidated statements of cash flows. As a result of the adoption of ASU 2016-18, for the nine-months ended September 30, 2017 operating cash flows increased by $0.6 million, which is reflected within the change in other assets caption.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). Under Topic 606, revenue is recognized when a customer obtains control of promised goods or services and is recognized at an amount that reflects the consideration expected to be received in exchange for such goods or services. In addition, Topic 606 requires disclosure of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

The Company adopted Topic 606 in the first quarter of 2018 using the modified retrospective method. This adoption, which required us to evaluate incomplete contracts as of January 1, 2018, related to the Company’s point of sale revenue, management, leasing and development fee arrangements and other sundry income. The Company’s analysis of incomplete contracts resulted in no restatement of the consolidated balance sheets and statements of operations presented in its consolidated financial statements. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606. The new guidance provides a unified model to determine how revenue is recognized. To determine the proper amount of revenue to be recognized, the Company performs the following steps: (i) identify the contract with the customer, (ii) identify the performance obligations within the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations and (v) recognize revenue when (or as) a performance obligation is satisfied.

| (a) | Corporate includes intercompany eliminations necessary to reconcile to consolidated Company totals.

Rental Revenue

The Company owns, operates and manages commercial real estate. Rental revenue is earned by leasing commercial space to the Company’s tenants. Rental revenue is recognized on a straight-line basis over the term of the leases. The Company’s primary source of revenue is leases which fall under the scope of Leases (Topic 840).

Point of Sale Revenue

Point of sale revenue consists of parking and flexible stay revenue from the Company’s hotel operations. Point of sale service obligations are performed daily, and the customer obtains control of those services simultaneously as they are performed. Accordingly, revenue is recorded on an accrual basis as it is earned, coinciding with the services that are provided to the Company’s customers. Due to the nature of the services provided to the Company’s customers, there is a nominal amount of unearned revenue recorded as deposits on the Company’s balance sheet related to its parking and flexible stay operations.

Tenant Reimbursements

The Company contracts with third-party vendors and suppliers for goods and services to fulfill certain of the Company’s obligations to tenants. The Company is reimbursed by tenants for these goods and services in the period that the expenses are incurred based on the terms of the lease agreements with each tenant.

21

Third party management fees, labor reimbursement and leasing

The Company performs property management services for third-party property owners of real estate that consist of: (i) providing leasing services, (ii) property inspections, (iii) repairs and maintenance monitoring, and (iv) financial and accounting oversight. For these services, the Company earns management fees monthly, which are based on a fixed percentage of each managed property’s financial results, and is reimbursed for the labor costs incurred by its property management employees as services are rendered to the property owners. The Company determined that control over the services is passed to its customers simultaneously as performance occurs. Accordingly, management fee revenue is earned as the services are provided to the Company’s customers.

Lease commissions are earned when the Company, as a broker for the third party property owner, executes a lease agreement with a tenant. Based on the terms of the Company’s lease commission contracts, it determined that control is transferred to the customer upon execution of each lease agreement. The Company’s lease commissions are earned based on a fixed percentage of rental income generated for each executed lease agreement and there is no variable income component.

Development fee revenue is earned through two different sources: (i) the Company performs development services for third parties as agent and earns fixed development fees based on a percentage of construction costs incurred over the construction period, and (ii) the Company acts as a general contractor on behalf of one of its managed real estate ventures. The Company acts as the principal construction company for the real estate venture and records gross revenue as it provides construction services based on the quantifiable construction outputs.

In applying the cost based output method of revenue recognition, the Company uses the actual costs incurred relative to the total estimated costs to determine its progress towards contract completion and to calculate the corresponding gross revenue and gross profit to recognize. For any costs that do not contribute to satisfying the Company’s performance obligations, it excludes such costs from its output methods of revenue recognition as the amounts are not reflective of transferring control of the outputs to the customer. The use of estimates in this calculation involves significant judgment.

Other Income

Other income primarily consists of sundry revenue earned for services provided to tenants. Sundry revenues are recognized simultaneously with the services provided to the Company’s tenants.

Contract assets and contract liabilities

As of September 30, 2018, the Company has no outstanding assets or liabilities associated with the Company’s third party management contracts.

Nonfinancial Assets

In February 2017, the FASB issued ASU No. 2017-05, Gains and losses from the derecognition of nonfinancial assets (ASC 610-20), to provide guidance for recognizing gains and losses from the transfer of nonfinancial assets and in-substance nonfinancial assets in contracts with non-customers, unless other specific guidance applies. The standard requires a company to derecognize nonfinancial assets once it transfers control of a distinct nonfinancial asset or distinct in-substance nonfinancial asset. Additionally, when a company transfers its controlling interest in a nonfinancial asset but retains a noncontrolling ownership interest, a company is required to measure any noncontrolling interest it receives or retains at fair value. The guidance requires companies to recognize a full gain or loss on the transaction. As a result of the new guidance, the previous guidance specific to real estate sales within ASC 360-20 will be eliminated.

The Company adopted ASU 2017-05 in the first quarter of 2018 using the modified retrospective method. This adoption requires the Company to analyze incomplete contracts related to property dispositions previously accounted for under ASC 360-20 and to determine whether such arrangements had any forms of continuing involvement that may have affected the revenue or profit recognition of the transactions, including arrangements with prohibited forms of continuing involvement. The Company evaluated the following incomplete contracts to determine if the revenue recognition pattern was affected by ASU 2017-05:

22

Garza Land Sales

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 purchase price of $20.6 million. As of September 30, 2018, the Company sold three parcels containing 8.4 acres, 1.7 acres and 6.6 acres to three unaffiliated third parties. Two of the land parcels were sold to third party developers on January 30, 2017 and April 28, 2017 and the third land parcel was sold to a third party on March 16, 2018. In connection with the agreements of sale, the Company entered into a development agreement and related completion guarantee to construct certain infrastructure improvements to the land. These improvement costs were included in the sale price of each land parcel. Due to the completion guarantee, the Company did not transfer control to the buyers of the land parcels and recognition of the sale was deferred until the improvements were substantially complete. The cash received at settlement was recorded as “Deferred income, gains and rent” on the Company’s consolidated balance sheets.

During the three-month period ended June 30, 2018, the infrastructure improvements were substantially completed. As a result, the Company transferred control of the land parcels to the buyers and recognized the land sales. Accordingly, during the three-month period ended June 30, 2018, the Company applied the cash proceeds received from the settlements of each parcel and recognized an aggregate $2.8 million deferred gain. There was no activity or gain recognized during the three-month period ended September 30, 2018. The following table details the gain on sale for each land parcel, as of September 30, 2018 (dollars, in thousands):

Disposition Date |  | Property/Portfolio Name |  | Location |  | Number of Parcels |  |  | Acres |  |  | Sales Price |  |  | Net Proceeds on Sale |  |  | Gain on Sale |
March 16, 2018 |  | Garza Ranch - Office |  | Austin, TX |  |  | 1 |  |  |  | 6.6 |  |  | $ | 14,571 |  |  | $ | 14,509 |  |  | $ | 1,424 |
April 28, 2017 |  | Garza Ranch - Multifamily |  | Austin, TX |  |  | 1 |  |  |  | 8.4 |  |  |  | 11,800 |  |  |  | 11,560 |  |  |  | 1,233 |
January 30, 2017 |  | Garza Ranch - Hotel |  | Austin, TX |  |  | 1 |  |  |  | 1.7 |  |  |  | 3,500 |  |  |  | 3,277 |  |  |  | 180 |
Total Dispositions |  |  |  |  |  |  | 3 |  |  |  | 16.7 |  |  | $ | 29,871 |  |  | $ | 29,346 |  |  | $ | 2,837 |

Based on the facts and circumstances, revenue recognition under ASU 2017-05 coincides with the Company’s conclusion under ASC 360-20, and no restatement of the consolidated financial statements is necessary as a result of implementing the guidance for the sale of nonfinancial assets.

Marine Piers Sublease Interest Sale

On March 15, 2017, the Company sold its sublease interest in the Piers at Penn’s Landing (the “Marine Piers”), which includes leasehold improvements containing 181,900 net rentable square feet, and a marina, located in Philadelphia, Pennsylvania, for an aggregate sales price of $21.4 million. On the closing date, the buyer paid $12.0 million in cash and the Company received cash proceeds of $11.2 million, after closing costs and prorations. The $9.4 million balance of the purchase is due on (a) January 31, 2020, in the event that the tenant at the Marine Piers does not exercise an option it holds to extend the term of the sublease or (b) January 15, 2024, in the event that the tenant does exercise the option to extend the term of the sublease. In accordance with ASU 2017-05, the Company determined that it is appropriate to recognize the sale of the sublease interest in the Marine Piers and to defer the amount of the pending payment due from the buyer because the Company cannot determine the collectability of the remaining $9.4 million balance due under the purchase and sale agreement. The net book value of the Marine Piers was $4.7 million, resulting in a gain on sale of $6.5 million. The remaining gain on sale of $9.4 million arising from the pending payment will be recognized at the earlier of: (i) the time that the Company determines collection of the deferred payment is probable or (ii) on the second purchase price installment date. Based on the facts and circumstances, revenue recognition under ASU 2017-05 coincides with the Company’s previous conclusion under ASC 360-20, and therefore no restatement of the consolidated financial statements is necessary as a result of implementing the guidance for the sale of nonfinancial assets.

Subaru National Training Center

On December 3, 2015, the Company entered into an agreement to construct an 83,000 square foot build-to-suit service center (the “Subaru NSTC Development”) on land parcels owned by the Company for Subaru as the single tenant. Concurrently, Subaru entered into an 18-year lease for the service center. The lease is classified as a direct finance lease within the “Other assets” caption on the consolidated balance sheets. The lease contained a purchase option, which allowed Subaru to purchase the property at the commencement of the lease, or five years subsequent to inception, at depreciated cost. During the third quarter of 2018, the lease commenced and Subaru exercised its purchase option for the Subaru NSTC Development. Accordingly, the Company recognized $0.4 million in interest income during the three months ended September 30, 2018, in accordance with accounting guidance for sales-type leases.

Recent Accounting Pronouncements

In June 2018, the FASB issued ASU No. 2018-07 that aligns the accounting for share-based payment awards issued to employees and nonemployees. Under previously issued GAAP guidance, the accounting for nonemployee share-based payments differed from that applied to employee awards, particularly with regard to the measurement date and the impact of performance conditions. Under the revised guidance, the existing employee guidance will apply to nonemployee share-based transactions (as long as the transaction is not effectively a form of financing), with the exception of specific guidance related to the attribution of compensation cost. The cost of nonemployee awards will continue to be recorded as if the grantor had paid cash for the goods or services. In addition, the contractual term will be able to be used in lieu of an expected term in the option-pricing model for nonemployee awards. Changes to the accounting for nonemployee awards include:

| • | Equity-classified share-based payment awards issued to nonemployees will now be measured on the grant date, instead of the previous requirement to remeasure the awards through the performance completion date.

| • | Compensation cost associated with the award will be recognized when achievement of the performance condition is probable, rather than upon achievement of the performance condition.

| • | The current requirement to reassess the classification (equity or liability) for nonemployee awards upon vesting will be eliminated, except for awards in the form of convertible instruments.

| • | The revised guidance also clarifies that any share-based payment awards issued to customers should be evaluated under ASC 606, Revenue from Contracts with Customers.

The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company is in the process of evaluating the impact of this new guidance on its consolidated financial statements.

In August 2017, the FASB issued ASU No. 2017-12 to simplify the application of hedge accounting guidance and improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. In addition, ASU 2017-12 requires an entity to present the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported. The transition guidance provides companies with the option of early adopting the new standard using a modified retrospective transition method in any interim period after issuance of the update or requires adoption for fiscal years beginning after December 15, 2018. This adoption method requires companies to recognize the cumulative effect of initially applying the guidance as an adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the update. The Company is in the process of evaluating the impact of this new guidance on its consolidated financial statements.

Leasing Standard

In February 2016, the FASB issued guidance (“ASU-2016-02”) 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 lease ASU requires the use of the modified retrospective transition method and does not allow for a full retrospective approach. However, it provides two options for application of the modified retrospective transition method:

| • | Under the first option, the ASU requires the application of the standard to all leases that exist at or commence after, January 1, 2017 (the beginning of the earliest comparative period presented in the 2019 financial statements), with a cumulative adjustment to the opening balance of retained earnings on January 1, 2017, for the effect of applying the standard at the date of initial applications, and restatement of the amounts presented prior to January 1, 2019.

| • | Under the second option, an entity may elect a package of practical expedients, which allows for the following:

| o | An entity need not reassess whether any expired or existing contracts are or contain leases;

| o | An entity need not reassess the lease classification for any expired or existing leases; and

| o | An entity need not reassess initial direct costs for any existing leases.

This package of practical expedients is available as a single election that must be consistently applied to all existing leases at the date of adoption. Lessors that adopt this package are not expected to reassess expired or existing leases at the date of initial application, which is January 1, 2017, under the ASU. This option enables entities to account for their existing leases for the remainder of the respective lease terms following previous accounting guidance, which eliminates the need to calculate a cumulative adjustment to the opening balance of retained earnings.

In addition, there is a practical expedient that allows the Company to use hindsight when determining the lease term and assessing the fair value of right of use assets. After considering its impact, the Company has decided not to elect the hindsight expedient as part of the application of the modified retrospective transition method.

Furthermore, in July 2018, the FASB adopted an amendment to the package of practical expedients that provides an optional transition method to make January 1, 2019 the initial application date of the ASU, rather than January 1, 2017. Entities that elect both the package of practical expedients and the optional transitional method will apply the new lease ASU prospectively, to leases commencing or modified after January 1, 2019, and will not be required to apply the disclosures under the new lease ASU to comparative periods.

In January 2018, the FASB issued ASU No. 2018-01 to address the accounting treatment of land easements within the context of ASU No. 2016-02, Leases (Topic 842). ASU 2018-01 provides an optional transition practical expedient to not evaluate under Topic 842 existing or expired land easements that were not previously accounted for as leases under the current leases guidance in Topic 840. An entity that elects this practical expedient should evaluate new or modified land easements under Topic 842 beginning at the date that the entity adopts Topic 842. An entity that does not elect this practical expedient should evaluate all existing or expired land easements in connection with the adoption of the new lease requirements in Topic 842 to assess whether they meet the definition of a lease.

In July 2018, the FASB issued ASU No. 2018-11, an amendment to the lease ASU that will allow lessors to elect, as a practical expedient, not to allocate the total consideration to lease and nonlease components based on their relative standalone selling prices. This practical expedient will allow lessors to elect a combined single lease component presentation if: (i) the timing and pattern of the revenue recognition of the combined single lease component is the same, and (ii) the related lease component and, the combined single lease component would be classified as an operating lease. Nonlease components that do not meet the criteria of this practical expedient will be accounted for under the new revenue recognition ASU.

The guidance is effective on January 1, 2019, with early adoption permitted. The ASU is expected to have the following impact on the Company’s consolidated financial statements:

| • | Under ASC 842 as a lessor, lease components are recognized on a straight line basis, while non-lease components will be recognized in accordance with the new revenue standard. The Company is in the process of evaluating its leases to determine if the timing and pattern of recognition for its lease and nonlease components is the same. If it is determined that the pattern of revenue recognition is the same for lease and nonlease components then the Company will present them within rental revenue in its consolidated statement of operations. The Company is in the process of evaluating the impact the ASU will have on its consolidated financial statements.

| • | ASC 842 is expected to impact the Company’s consolidated financial statements as the Company has land lease arrangements for which it is the lessee. Based on the Company’s evaluation, it expects operating expenses to increase by $0.8 million as ground rent expense for certain of its CPI indexed ground leases will be recognized on a straight-line basis under the new guidance.

| • | The Company will expense additional costs related to leasing efforts under ASC 842 compared to the previous GAAP because certain activities performed by personnel involved in the leasing process will no longer be considered incremental costs to execute a lease agreement. Based on the Company’s analysis, leasing expenses will increase by $3.6 million for the year ended December 31, 2019, as internal costs and leasing pursuit costs will be expensed as incurred under ASC 842.

| • | The Company’s equity-method investments may adopt the standard using the timeline otherwise afforded private companies. The Company anticipates the impact of ASC 842 will be similar to the items described above.

The Company has not completed its analysis of this ASU. The Company expects tenant recoveries that qualify as nonlease components will be presented under a single lease component presentation. Tenant recoveries that qualify as lease components, which relate to the right to use the leased asset (e.g., property taxes, and insurance), will be accounted for under the new lease ASU. Tenant recoveries that qualify as nonlease components, which relate to payments for goods or services that are transferred separately from the right to use the underlying asset, including tenant recoveries pertaining to payments for maintenance activities and common area expenses, would be accounted for under the new revenue recognition ASU upon adoption of the new lease ASU. Additionally, the Company has determined that it is going to elect to apply the package of practical expedients when applying the modified retrospective approach.

Acquisitions

On June 29, 2018, the Company acquired, through a 99-year ground lease, the leasehold interest in a one-acre land parcel, located at 3025 JFK Boulevard, in Philadelphia, Pennsylvania. The Company prepaid $15.0 million of ground lease rent and, in accordance with ASC 840, capitalized $0.3 million of costs related to entering the lease. Additionally, the ground lease required the Company to pay $5.6 million for a leasehold valuation credit, which can be applied to increase the density of the projects subject to the Schuylkill Yards Project master development agreement. Of this credit, $2.4 million will be applied to the development of 3001-3003 and 3025 JFK Boulevard if the Company constructs a minimum of 1.2 million square feet of floor area ratio (“FAR”) on these land parcels. The remaining credit of $3.2 million can be used for development in excess of 1.2 million FAR at 3001-3003 and 3025 JFK Boulevard or toward future ground lease takedowns at the Schuylkill Yards Development Site. This $3.2 million credit is reimbursed if the master development agreement is terminated by the landowner. Based on the Company’s evaluation under ASC 840, the ground lease is classified as an operating lease. The ground lease and credit are included in the “Prepaid leasehold interests in land held for development, net,” and “Other assets” captions, respectively, in the consolidated balance sheets.

On March 22, 2018, the Company acquired, through a 99-year ground lease, the leasehold interest in a one-acre land parcel, located at 3001-3003 JFK Boulevard, in Philadelphia, Pennsylvania. The Company prepaid $24.6 million of ground lease rent and, in accordance with ASC 840, capitalized $0.3 million of costs related to entering the lease. Based on the Company’s evaluation under ASC 840, the ground lease is classified as an operating lease and included in the “Prepaid leasehold interests in land held for development, net,” caption in the consolidated balance sheets.

On January 5, 2018, the Company acquired, from its then partner in each of the Four Tower Bridge real estate venture and the Seven Tower Bridge real estate venture, the partner’s 35% ownership interest in the Four Tower Bridge real estate venture in exchange for the Company's 20% ownership interest in the Seven Tower Bridge real estate venture. As a result of this non-monetary exchange, the Company acquired 100% of the Four Tower Bridge real estate venture, which owns an office property containing 86,021 square feet, in Conshohocken, Pennsylvania, encumbered with $9.7 million in debt. The Company previously accounted for its noncontrolling interest in Four Tower Bridge using the equity method. As a result of the exchange transaction, the Company obtained control of the Four Tower Bridge property.

The Company’s acquisition of the 35% ownership interest in Four Tower Bridge from its former partner resulted in the consolidation of the property, which has been accounted for as an asset acquisition under ASU 2017-01. As such, the Company capitalized $0.1 million of acquisition-related costs and allocated the unencumbered acquisition value, consisting of the fair value of $23.6 million and the acquisition-related costs, to tangible and intangible assets and liabilities. The unencumbered acquisition value was determined under the comparative sales approach, which utilized observable transactions within the Conshohocken submarket.

(a) | As of March 31, 2018, the Company had not transferred control to the buyer of this land parcel, or two other parcels at this site which were sold during 2017, because of a completion guarantee which required the Company, as developer, to complete certain infrastructure improvements on behalf of the buyers of the land parcels. The cash received at settlement was recorded as “Deferred income, gains and rent” on the Company’s consolidated balance sheets. During the three months ended June 30, 2018, the infrastructure improvements were substantially completed, at which time the Company transferred control of the land parcels. As a result, the Company then recognized the sale. See Note 2, “Basis of Presentation,” for further discussion of the infrastructure improvements and related revenue recognition.

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

| (a) | As of September 30, 2018, the Company determined that the sale of eight office properties, containing 1,293,197 rentable square feet, in the Metropolitan Washington, D.C. segment, was probable and classified these properties as held for sale in accordance with applicable accounting standards for long-lived assets. At such date, the $366.0 million carrying value of the properties exceeded the estimated $309.1 million fair value less the anticipated costs of sale. As a result, the Company recognized an impairment loss totaling approximately $56.9 million during the three-month period ended September 30, 2018. The Company measured this impairment based on a discounted cash flow analysis, using a hold period of ten years and residual capitalization rates and discount rates of 7.47% and 8.60%, respectively. The results were comparable to indicative pricing in the market. 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) | As of September 30, 2018, the Company determined that the sale of one land parcel in the Pennsylvania Suburbs segment and two parcels of land in the Other segment was probable and classified these properties as held for sale in accordance with applicable accounting standards for long-lived assets. At such date, the fair value less the anticipated costs of sale of the properties exceeded the carrying values. As a result, the Company expects to record gains on sale. The fair value measurement will be based on the pricing in the purchase and sale agreements.

The disposals of the properties referenced above do not represent a strategic shift that has a major effect on the operations and financial results of the Company. As a result, the operating results of the properties remain classified within continuing operations for all periods presented.

4. INVESTMENT IN UNCONSOLIDATED REAL ESTATE VENTURES

As of September 30, 2018, the Company held ownership interests in 10 unconsolidated Real Estate Ventures for an aggregate investment balance of $167.8 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 September 30, 2018, six of the real estate ventures owned properties that contain an aggregate of approximately 6.6 million net rentable square feet of office space; two real estate ventures owned 1.4 acres of land held for development; one real estate venture owned 1.3 acres of land in active development; and one real estate venture owned a residential tower that contains 321 apartment units.

The Company accounts for its unconsolidated interests in the Real Estate Ventures using the equity method. The Company’s unconsolidated interests range from 25% to 70%, subject to specified priority allocations of distributable cash in certain of the Real Estate Ventures.

28

The Company earned management fees from its Real Estate Ventures of $1.4 million and $4.0 million for the three- and nine-month periods ended September 30, 2018, respectively, and $1.7 million and $4.9 million for the three- and nine-month periods ended September 30, 2017, respectively.

The Company earned leasing commission income from its Real Estate Ventures of $1.5 million and $4.4 million for the three- and nine-month periods ended September 30, 2018, respectively, and $1.9 million and $5.5 million for the three- and nine-month periods ended September 30, 2017, respectively.

The Company had outstanding accounts receivable balances from its Real Estate Ventures of $1.2 million and $0.9 million as of September 30, 2018 and December 31, 2017, 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 in which the Company held interests as of September 30, 2018 and December 31, 2017 (in thousands):

(b) | 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.

MAP Venture

On August 1, 2018, MAP Ground Lease Venture LLC (“MAP Venture”), in which the Company holds a 50% ownership interest, refinanced its $180.8 million third party debt financing, secured by the buildings of MAP Venture and maturing February 9, 2019, with $185.0 million third party debt financing, also secured by the buildings, bearing interest at LIBOR + 2.45% capped at a total maximum interest of 6.00% and maturing on August 1, 2023.

The Company accounts for its investment in MAP Venture under the equity method of accounting. Based upon the reconsideration event caused by the refinancing of the MAP Venture’s third party debt financing, 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 MAP Venture, through the refinancing of the construction facility and without further support from the Company or its partner in the venture, demonstrated that it has sufficient equity at risk to finance its activities. As a result, the Company is using the voting interest model under the accounting standard for consolidation in order to determine whether to consolidate MAP Venture. Based upon each member's substantive participating rights over the activities that significantly impact the operations and revenues of MAP Venture under the operating agreement and related agreements, MAP Venture is not consolidated by the Company, and is accounted for under the equity method of accounting. As a result of this transaction, the Company did not gain a controlling financial interest over MAP Venture; 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.

Brandywine 1919 Ventures

On June 26, 2018, each of the Company and its partner, LCOR/Calstrs, provided a $44.4 million mortgage loan to Brandywine 1919 Ventures (“1919 Ventures”), an unconsolidated real estate venture in which each of the Company and LCOR/Calstrs holds a 50% ownership interest. As a result, the Company recorded a related-party note receivable of $44.4 million in the “Other assets” caption on its

31

consolidated balance sheets. The loans bear interest at a fixed 4.0% per annum interest rate with a scheduled maturity on June 25, 2023. On June 26, 2018, Brandywine 1919 Ventures used the loan to repay the venture’s then outstanding $88.8 million construction loan, comprised of $88.6 million in principal and $0.2 million of accrued interest. On an ongoing basis, the Company will evaluate its loan for collectability. There are no collectabili ty concerns as of September 30, 2018.

The Company accounts for its investment in 1919 Ventures under the equity method of accounting. Based upon the reconsideration event caused by the refinancing of 1919 Ventures’ 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. As a result, the Company is using the voting interest model under the accounting standard for consolidation in order to determine whether to consolidate 1919 Ventures. The partner mortgage loans do not impact the controlling rights within the partnership agreements. Based upon each member's substantive participating rights over the activities that significantly impact the operations and revenues of 1919 Ventures under the operating agreement and related partnership agreements, 1919 Ventures is not consolidated by the Company, and is accounted for under the equity method of accounting. As a result of this transaction, the Company did not gain a controlling financial interest over 1919 Ventures; 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.

Four Tower Bridge Acquisition

On January 5, 2018, the Company acquired, from its then partner in each of the Four Tower Bridge real estate venture and the Seven Tower Bridge real estate venture, the partner’s remaining 35% ownership interest in the Four Tower Bridge real estate venture in exchange for the Company's 20% ownership interest in the Seven Tower Bridge real estate venture. The Four Tower Bridge real estate venture owned an office property containing 86,021 square feet in Conshohocken, Pennsylvania encumbered with $9.7 million in debt. The Company previously accounted for its noncontrolling interest in Four Tower Bridge using the equity method. As a result of the exchange transaction, the Company obtained control of the Four Tower Bridge property and recognized a gain of $11.6 million. For further information regarding the accounting of the transaction, see Note 3, “Real Estate Investments.”

evo at Cira Disposition

On January 10, 2018, evo at Cira, a real estate venture in which the Company held a 50% interest, sold its sole asset, a 345-unit student housing tower, at a gross sales value of $197.5 million. The student housing tower, located in Philadelphia, Pennsylvania, was encumbered by a secured loan with a principal balance of $110.9 million at the time of sale, which was repaid in full from the sale proceeds. The Company’s share of net cash proceeds from the sale, after debt repayment and closing costs, was $43.0 million. As the Company’s investment basis was $17.3 million, a gain of $25.7 million was recorded.

Guarantees

As of September 30, 2018, the Real Estate Ventures had aggregate indebtedness of $664.2 million. These loans are generally mortgage or construction loans, most of which are non-recourse to the Company, except for customary carve-outs. As of September 30, 2018, the loans for which there is recourse to the Company consist of the following: (i) a $0.4 million payment guarantee on a loan with a $4.2 million outstanding principal balance, provided to PJP VII and (ii) up to a $41.3 million payment guarantee on a $150.0 million construction loan provided to 4040 Wilson. In addition, during construction undertaken by real estate ventures, including 4040 Wilson, 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.

(a) | This loan was assumed upon acquisition of the related property on January 5, 2018. The interest rate reflects the market rate at the time of acquisition.

As of September 30, 2018 and December 31, 2017, the Company’s weighted-average effective interest rates on its mortgage notes payable were 4.05% and 4.04%, respectively.

On July 17, 2018, the Company executed the Amended and Restated Revolving Credit Agreement (as amended and restated, the “2018 Credit Facility”). The amendment and restatement, among other things: (i) maintained the total commitment of the revolving line of credit of $600.0 million; (ii) extended the maturity date from May 15, 2019 to July 15, 2022, with two six-month extensions at the Company’s election subject to specified conditions and subject to payment of an extension fee; (iii) reduced the interest rate margins applicable to Eurodollar loans; (iv) provided for an additional interest rate option based on a floating LIBOR rate; and (v) removed the covenant requiring the Company to maintain a minimum net worth. In connection with the amendments, the Company capitalized $2.7 million in financing costs, which will be amortized through the July 15, 2022 maturity date.

At the Company's option, loans outstanding under the 2018 Credit Facility will bear interest at a rate per annum equal to (1) LIBOR plus between 0.775% and 1.45%, based on the Company's credit rating, or (2) a base rate equal to the greatest of (a) the Administrative Agent's prime rate, (b) the Federal Funds rate plus 0.5% or (c) LIBOR for a one month period plus 1.00%, in each case, plus a margin ranging from 0.0% to 0.45% based on the Company's credit rating. The 2018 Credit Facility also contains a competitive bid option that allows banks that are part of the lender consortium to bid to make loan advances to the Company at a reduced interest rate. In addition, the Company is also obligated to pay (1) in quarterly installments a facility fee on the total commitment at a rate per annum ranging from 0.125% to 0.30% based on the Company's credit rating and (2) an annual fee on the undrawn amount of each letter or credit equal to the LIBOR Margin. Based on the Company's current credit rating, the LIBOR margin is 1.10% and the facility fee is 0.25%.

34

The terms of the 2018 Credit Facility require that the Company maintain customary financial and other covenants, including: (i) a fixed charge coverage ratio greater than or equal to 1.5 to 1.00; (ii) a leverage ratio less than or equal to 0.60 to 1.00, subject to specified exceptions; (iii) a ratio of unsecured indebtedness to unencumbered asset value less than or equal to 0.60 to 1.00, subject to specified exceptions; (iv) a ratio of secured indebtedness to total asset value less than or equal to 0.40 to 1.00; and (v) a ratio of unencumbered cash flow to interest expense on unsecured debt greater than 1.75 to 1.00. In addition, the Credit Facility restricts payments of dividends and distributions on shares in excess of 95% of the Company's funds from operations (FFO) except to the extent necessary to enable the Company to continue to qualify as a REIT for Federal income tax purposes.

The Company had no borrowings under the 2018 Credit Facility as of and during the nine-month period ended September 30, 2018. As of September 30, 2017, the Company had $178.0 million of borrowings under the Credit Facility and $13.5 million in letters of credit outstanding. During the nine months ended September 30, 2017, the weighted-average interest rate on Credit Facility borrowings was 2.34%. As of September 30, 2017, the effective interest rate on Credit Facility borrowings was 2.43%.

Concurrently with its entry into the 2018 Credit Facility, the Company terminated its then existing unsecured revolving credit facility, which had a scheduled maturity date of May 15, 2019. 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 September 30, 2018. Management continuously monitors the Company’s current and anticipated compliance with the covenants. Certain of the covenants restrict the Company’s ability to obtain alternative sources of capital.

As of September 30, 2018, the Company’s aggregate scheduled principal payments of debt obligations, excluding amortization of discounts and premiums, are as follows (in thousands):

2018 (three months remaining) | $ | 1,854 |
2019 |  | 7,595 |
2020 |  | 87,226 |
2021 |  | 15,143 |
2022 |  | 256,332 |
Thereafter |  | 1,585,346 |

Outstanding indebtedness | $ | 1,937,537 |

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.

35

The Company determined the fair values disclosed below using available market information and discounted cash flow analyses as of September 30, 2018 and December 31, 2017, respectively. The discount rate used in calculating fair value is the sum of the c urrent 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 ar e 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 amoun ts reflected in the consolidated balance sheets at September 30, 2018 and December 31, 2017 approximate the fair values for cash and cash equivalents, accounts receivable, other assets (except for the note receivable disclosed below), accounts payable an d accrued expenses. The following are financial instruments for which the Company’s estimates of fair value differ from the carrying amounts (in thousands):

| September 30, 2018 |  |  | December 31, 2017 |
| Carrying Amount (a) |  |  | Fair Value |  |  | Carrying Amount (a) |  |  | Fair Value |
Unsecured notes payable | $ | 1,287,661 |  |  | $ | 1,249,225 |  |  | $ | 1,286,573 |  |  | $ | 1,314,900 |
Variable rate debt | $ | 327,288 |  |  | $ | 310,640 |  |  | $ | 327,039 |  |  | $ | 308,872 |
Mortgage notes payable | $ | 322,588 |  |  | $ | 314,813 |  |  | $ | 317,216 |  |  | $ | 304,665 |
Notes receivable (b) | $ | 47,821 |  |  | $ | 47,858 |  |  | $ | 3,532 |  |  | $ | 3,605 |

(a) | The carrying amounts presented in the table above are net of deferred financing costs of $8.2 million and $8.9 million for unsecured notes payable, $1.4 million and $1.3 million for variable rate debt and $0.4 million and $0.6 million for mortgage notes payable as of September 30, 2018 and December 31, 2017, respectively.

(b) | The inputs to originate the notes receivable are unobservable and, as a result, are categorized as Level 3. The Company determined fair value by calculating the present value of the cash payments to be received through the maturity date of the loans.

On June 26, 2018, the Company provided a $44.4 million mortgage loan to Brandywine 1919 Ventures, an unconsolidated real estate venture in which the Company holds a 50% ownership interest, and recorded a note receivable of $44.4 million. For additional information regarding the transaction, see Note 4, “Investment in Unconsolidated Real Estate Ventures.”

As of September 30, 2018, notes receivable also consisted of a $3.4 million note receivable that was provided to a third party to acquire a property. The mortgage bears interest at 7.0% through March 2019 and 8.0% interest thereafter until its maturity date in March of 2020. The loan principal amortizes down to the balloon payment of $3.1 million which the Company expects to receive at maturity of the note in March of 2020.

The Company periodically assesses collectability of the notes receivable in accordance with the accounting standard for loan receivables. As of September 30, 2018, the Company’s notes receivable are collectible.

The inputs utilized to determine the fair value of the Company’s unsecured notes payable are categorized as Level 2. This is because the Company valued these instruments using quoted market prices as of September 30, 2018 and December 31, 2017. 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 inputs utilized to determine the fair value of the Company’s mortgage notes payable and variable rate debt are categorized as Level 3. 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 payments by a blended market rate for loans with similar terms, maturities and loan-to-value. These inputs have been categorized as Level 3 because the Company considers the rates used in the valuation techniques to be unobservable inputs.

The inputs to originate the notes receivable are unobservable and, as a result, are categorized as Level 3. The Company determined fair value by calculating the present value of the cash payments to be received through the maturity dates of the loans.

For the Company’s mortgage loans, the Company uses an estimate based discounted cash flow analyses and its knowledge of the mortgage market. 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 September 30, 2018 and December 31, 2017. 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 September 30, 2018, 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.

(a) | Hedging unsecured variable rate debt.

The Company measures its derivative instruments at fair value and records them in the “Other assets” and (“Other liabilities”) captions on the Company’s consolidated balance sheets.

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 the inputs utilized to determine the fair value of derivative instruments are classified in Level 2 of the fair value hierarchy.

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. 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. All companies may n ot calculate NOI in the same manner. NOI is the measure that is used by the Company’s management to evaluate the operating performance of the Company’s real estate assets by segment. The Company believes NOI provides useful information to investors regardi ng the 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 imp airment losses, depreciation and amortization costs, capital expenditures and leasing costs. The Company believes that net income (loss), as defined by GAAP, is the most appropriate earnings measure. The following is a reconciliation of consolidated net in come, as defined by GAAP, to consolidated NOI, (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, vendors 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 Company does not expect that the liabilities, if any, that may ultimately result from such legal actions will have a material adverse effect on the consolidated financial position, results of operations or cash flows of the Company.

Letters-of-Credit

Under certain mortgages, including mortgages held by Real Estate Ventures, the Company may be required to fund required leasing and capital reserve accounts for the benefit of the mortgage lenders with a letter-of-credit. There were no associated letters-of-credit for a mortgage lender on September 30, 2018. 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

42

the Company does not believe it will have a mat erial 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, excluding prepaid ground leases, have remaining lease terms ranging from 10 to 66 years. Minimum future rental payments on non-cancelable leases at September 30, 2018 are as follows (in thousands):

Year |  | Minimum Rent |
2018 (three months remaining) |  | $ | 306 |
2019 |  |  | 1,222 |
2020 |  |  | 1,222 |
2021 |  |  | 1,222 |
2022 |  |  | 1,222 |
Thereafter |  |  | 56,911 |
Total |  | $ | 62,105 |

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, 2017 for further detail regarding commitments and contingencies.

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 unobservable, the Company determined the inputs used to value this liability fall within Level 3 for fair value reporting. As of September 30, 2018, the liability had accreted to $1.9 million. As there were no significant changes to the inputs, the liability remains within Level 3 for fair value reporting.

Debt Guarantees

As of September 30, 2018, the Company’s unconsolidated real estate ventures had aggregate indebtedness of $664.2 million. These loans are generally mortgage or construction loans, most of which are non-recourse to the Company, except for customary recourse carve-outs. As of September 30, 2018, the loans for which the Company has provided recourse guarantees consist of the following: (i) a $0.4 million payment guarantee on a loan with a $4.2 million outstanding principal balance, provided to PJP VII and (ii) up to a $41.3 million payment guarantee on a $150.0 million loan provided to 4040 Wilson.

Other Commitments or Contingencies

On October 13, 2017, the Company acquired a leasehold interest in the office building known as One Drexel Plaza, in Philadelphia, Pennsylvania. In connection with the acquisition, the Company is required to spend no less than $8.0 million in capital improvements to the property. Funding related to this requirement had not yet begun as of September 30, 2018. The Company estimates that it will incur $37.3 million in excess of this funding requirement and expects to complete the redevelopment of One Drexel Plaza during the second quarter of 2020 at an estimated aggregate cost of $83.1 million, inclusive of the acquisition cost of $37.8 million.

Also on October 13, 2017, the Company acquired a leasehold interest in the land parcel at 3001 Market Street in Philadelphia, Pennsylvania (“Drexel Square”). During the fourth quarter of 2017, the Company broke ground on the construction of a public park on the site, marking the commencement of construction at our Schuylkill Yards Project with Drexel. Under the terms of the Development Agreement with Drexel University, the Company has until July 2019 to complete development of Drexel Square. If the Company is unable to complete such development within this timeframe, it may be subject to damages under the Development Agreement.

43

During the fourth quarter of 2017, in connection with the Schuylkill Yards Project, the Company entered into a neighborhood engagement program and, as of September 30, 2018, had $2.7 million of future contractual obligations. In addition, the Company estimates $0.7 million of potential additional contributions for which the Company is not currently contractually obligated.

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 purchase price of $20.6 million. As of September 30, 2018, the Company sold three parcels containing 8.4 acres, 1.7 acres and 6.6 acres (of the 34.6 acres) to three unaffiliated third parties. In connection with the agreements of sale, the Company entered into a development agreement and related completion guarantee to construct certain infrastructure improvements to the land. These improvement costs were included in the sale price of each land parcel. Recognition of the sale of the land parcels was deferred until the improvements were substantially complete, which occurred during the second quarter of 2018. See Note 2, “Basis of Presentation,” to the consolidated financial statements for further discussion of the infrastructure improvements and related revenue recognition.

On December 3, 2015, the Company entered into an agreement to construct an 83,000 square foot build-to-suit service center (the “Subaru NSTC Development”) on land parcels owned by the Company for Subaru as the single tenant. On such date, Subaru entered into an 18-year lease for the service center. The lease contains a purchase option, which allows Subaru to purchase the property at commencement of the lease, or five years subsequent to inception, at depreciated cost. On May 18, 2018, Subaru exercised its option to purchase the property. The purchase price is equal to total project costs plus an 8% developer profit, as per the lease agreement. The closing date will be the later of: (i) 30 days following substantial completion of the project, and (ii) three business days following the completion of punch list items. At September 30, 2018, $34.5 million of the estimated project costs, totaling $47.6 million, had been funded, and is included within the “Other assets” caption of the consolidated balance sheets.

The Company invests in its properties and regularly incurs capital expenditures in the ordinary course of business 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.

14. SUBSEQUENT EVENTS

On October 16, 2018, the Company entered into an agreement to sell a portfolio of eight properties containing an aggregate of 1,293,197 square feet, located in the Metropolitan Washington, D.C. segment, for a gross sales price of $312.0 million. The Company will retain a 15% ownership interest in the properties through an unconsolidated real estate venture. After obtaining debt financing for the real estate venture, the Company anticipates receiving net cash receipts of approximately $292.0 million. As of September 30, 2018, the Portfolio was classified as held sale and the Company recorded an impairment of $56.9 million. As the properties were impaired to reflect the value of the estimated net cash proceeds, the Company does not anticipate a gain or loss upon settlement, which is expected to occur during the fourth quarter of 2018. For further information related to the impact to the consolidated balance sheets, see the “Held for Sale” section in Note 3, “Real Estate Investments.”

On October 17, 2018, the Company entered into an agreement to acquire its partner's entire 50% interest in the 12 remaining properties within the DRA Austin real estate venture, containing 1,570,123 square feet, located in Austin, Texas, for a gross sales price of $537.0 million. In connection with the acquisition, the Company will assume an estimated $245.8 million of mortgage debt. The Company expects the transaction to settle during the fourth quarter of 2018. As of September 30, 2018, the Company’s investment in the real estate venture is $14.4 million, and upon settlement, the Company expects to recognize a gain on the transaction, which will be reflected in the caption ‘Net gain on real estate transactions’ in its consolidated statements of operations.

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 under the heading “Forward-Looking Statements” in our Annual Report on Form 10-K for the year ended December 31, 2017.

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, 2017, 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 September 30, 2018 and December 31, 2017 and for the three- and nine-month periods ended September 30, 2018 and 2017 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 September 30, 2018, we owned 93 properties that contain an aggregate of approximately 16.5 million net rentable square feet (collectively, the “Properties”). Our core portfolio of operating properties, as of September 30, 2018, excludes two development properties and five redevelopment properties under construction or committed for construction (collectively, the “Core Properties”). The Properties were comprised of the following as of September 30, 2018:

|  |  | Number of Properties |  |  | Rentable Square Feet |  |  | Percentage Occupied |  |  | Percentage Leased |
Office properties |  |  |  | 73 |  |  |  | 13,673,405 |  |  |  |  |  |  |  |  |
Mixed-use properties |  |  |  | 4 |  |  |  | 646,741 |  |  |  |  |  |  |  |  |
Retail properties |  |  |  | 1 |  |  |  | 17,884 |  |  |  |  |  |  |  |  |
Core Properties |  |  |  | 78 |  |  |  | 14,338,030 |  |  | 93.0% |  |  | 95.0% |
Development properties |  |  |  | 2 |  |  |  | 247,818 |  |  |  |  |  |  |  |  |
Redevelopment properties |  |  |  | 5 |  |  |  | 583,719 |  |  |  |  |  |  |  |  |
Held for sale properties (a) |  |  |  | 8 |  |  |  | 1,293,197 |  |  |  |  |  |  |  |  |
The Properties |  |  |  | 93 |  |  |  | 16,462,764 |  |  |  |  |  |  |  |  |

(a) As of September 30, 2018, eight office properties were classified as held for sale in our Metropolitan Washington, D.C. segment. See Note 3, “Real Estate Investments,” for further information.

In addition, as of September 30, 2018, we owned economic interests in 10 unconsolidated real estate ventures (collectively, the “Real Estate Ventures”), six of which own properties that contain an aggregate of approximately 6.6 million net rentable square feet of office space; two of which own, in aggregate, 1.4 acres of land held for development; one that owns 1.3 acres in active development; and one that owns a residential tower that contains 321 apartment units.

In addition to the Properties, as of September 30, 2018 we owned land held for development, comprised of 234 acres of undeveloped land, of which 37.9 acres were held for sale, 1.8 acres related to leasehold interests in two land parcels each acquired through prepaid 99-year ground leases and held options to purchase approximately 55.5 additional acres of undeveloped land. As of September 30, 2018, the total potential development that these land parcels could support, including the parcels under option, amounted to an estimated 14.2 million square feet, of which 0.4 million square feet relates to 37.9 acres held for sale. 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; Wilmington, Delaware; Richmond, Virginia and Austin, Texas.

We conduct our third-party real estate management services business primarily through wholly-owned management company subsidiaries. As of September 30, 2018, the management company subsidiaries were managing properties containing an aggregate of approximately 25.3 million net rentable square feet, of which approximately 16.5 million net rentable square feet related to Properties

45

that we own and consolidate and approximately 8.8 million net rentable square feet related to properties owned by third parties and the Real Estate Ventures.

During the nine months ended September 30, 2018, we owned and managed properties within five markets: (1) Philadelphia Central Business District (“Philadelphia CBD”), (2) Pennsylvania Suburbs, (3) Metropolitan Washington, D.C., (4) Austin, Texas, and (5) Other. The Philadelphia CBD segment includes properties located in the City of Philadelphia in Pennsylvania. The Pennsylvania Suburbs segment includes properties in Chester, Delaware and Montgomery counties in the Philadelphia suburbs. 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 Camden County in New Jersey and properties in New Castle County in Delaware. In addition to the five markets, our 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.

We generate cash and revenue from leases of space at our Properties and, to a lesser extent, from the management and development 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 core to our business plan, 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, residential and retail 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 result in a reduction of the availability of financing and potentially in higher borrowing costs. Vacancy rates may increase, and rental rates may decline, during the remainder of 2018 and possibly beyond as the current economic climate may negatively impact tenants.

Overall economic conditions, including but not limited to higher unemployment and 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 adverse 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 the strength of our balance sheet will enable us to raise debt capital, if necessary, in various forms and from different sources, including through secured or unsecured 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 September 30, 2018 was 93.0% compared to 92.0% at September 30, 2017.

(2) | Includes leasing related to completed developments and redevelopments, as well as sold properties.

(3) | Rental rates include base rent plus reimbursement for operating expenses and real estate taxes.

(4) | Calculated on a weighted average basis.

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.

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 0.75% of our aggregate final annualized base rents as of September 30, 2018 (representing approximately 0.70% of the net rentable square feet of the properties) are scheduled to expire without penalty in 2018. 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 nine-month periods ended September 30, 2018 is 75.1% and 66.3% compared to a retention rate of 81.4% and 72.8% for the three- and nine-month periods ended September 30, 2017. 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 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 evaluates our accounts receivable reserve policy in light of our tenant base and general and local economic conditions. Our accounts receivable allowance was $17.3 million or 8.3% of total receivables (including accrued rent receivables) as of September 30, 2018 compared to $17.1 million or 8.4% of total receivables (including accrued rent receivables) as of December 31, 2017.

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.

47

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 September 30, 2018, the following development and redevelopment projects were under construction (dollars, in thousands):

(a) | The project is pre-leased to a single tenant. Total estimated costs include $2.1 million of land basis existing at project inception.

(b) | Subaru commenced its lease on August 23, 2018 and will remain a tenant until they purchase the building, which we expect upon completion of exterior improvements in the fourth quarter of 2018. See Note 2, “Basis of Presentation,” to the consolidated financial statements for further information.

(c) | Total project costs include $18.5 million of existing property basis. The base building has been partially placed into service. The remaining budgeted costs primarily relate to tenant improvements, as the building is not yet stabilized at 81.9% occupied. Stabilization is set to occur during the fourth quarter of 2018, at which point the property will be fully placed into service.

(d) | The project is pre-leased to a single tenant. Total project costs include $4.5 million of existing property basis.

(e) | Total project costs include $37.8 million of building basis, representing the acquisition cost. The amount funded, as of September 30, 2018, does not include any amounts related to an $8.0 million funding commitment required through the ground lease. See Item 2., "Liquidity and Capital Resources – Contractual Obligations" for further information regarding this commitment.

(f) | Drexel Square serves as an amenity to the Schuylkill Yards project and the costs are expected to be recovered through future development projects at Schuylkill Yards.

(g) | The property was vacated during the third quarter of 2017. Current plans are to renovate this building. Total project costs include $4.9 million of existing property basis.

Other Development Activities:

4040 Wilson Venture

4040 Wilson, a 50/50 real estate venture between Ashton Park and us, is developing a 427,500 square foot mixed-use building, representing the final phase of the eight building, mixed-use, Liberty Center complex located in the Ballston submarket of Arlington, Virginia. The project is being constructed on a 1.3-acre land parcel contributed by Ashton Park to 4040 Wilson. During the fourth quarter of 2017, 4040 Wilson achieved pre-leasing levels that enabled the venture to obtain a secured construction loan with a total borrowing capacity of $150.0 million for the remainder of the project costs. The total estimated project costs are $224.8 million, which we expect will be financed through approximately $74.8 million of partner capital contributions and $150.0 million in proceeds from the secured construction loan. As of September 30, 2018, $37.4 million had been advanced under the construction loan, and the venture had commenced construction of the mixed-use building. If construction costs were to exceed estimates, our equity method investment in 4040 Wilson could become other than temporarily impaired.

Schuylkill Yards Project

As of September 30, 2018, we remain in the planning and development phase of our master developer agreement (the “Development Agreement”) with Drexel University, a Pennsylvania non-profit corporation, and an affiliate of Drexel University, (collectively “Drexel”) for the Schuylkill Yards Project. For further information relating to this development, including an overview of the project, see Item 1., "Business - Developments" included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017. See below for information relating to the Schuylkill Yards Project during the nine months ended September 30, 2018.

On June 29, 2018, we acquired, through a 99-year ground lease, the leasehold interest in a one-acre land parcel located at 3025 JFK Boulevard, in Philadelphia, Pennsylvania. We prepaid $15.0 million of ground lease rent and capitalized $0.3 million of costs relating to entering into the lease. We plan to develop this property as part of the Schuylkill Yards Project and are currently in the process of determining the scope and timing of improvements. In addition, the ground lease required us to pay $5.6 million, which can be applied to increase the density of the projects subject to the Development Agreement. See "Recent Property Transactions - Acquisitions" below for further discussion of this acquisition.

On March 22, 2018, we acquired, through a 99-year ground lease, the leasehold interest in a one-acre land parcel located at 3001-3003 JFK Boulevard, in Philadelphia, Pennsylvania. We prepaid $24.6 million of ground lease rent and capitalized $0.3 million of costs relating to entering into the lease. We plan to develop this property as part of the Schuylkill Yards Project and are currently in the process of determining the scope and timing of improvements.

For information regarding the 2017 acquisitions within the scope of the Schuylkill Yards project, see Item 1., “Business – 2017 Transactions,” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

Reference is made to our Annual Report on Form 10-K for the year ended December 31, 2017 for project overviews, as well as risks associated with these development projects. See "Liquidity and Capital Resources – Contractual Obligations" below for contractual commitments relating to our ongoing development projects.

Land Holdings

As of September 30, 2018, we owned approximately 234 acres of undeveloped land, of which 37.9 acres were held for sale, 1.8 acres related to leasehold interests in two land parcels, each acquired through prepaid 99-year ground leases, and held options to purchase approximately 55.5 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 and rental rates. As of September 30, 2018, the total potential development that these land parcels could support amounted to 14.2 million square feet of development, of which 0.4 million square feet relates to 37.9 acres held for sale.

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. Additionally, we consider strategic decisions regarding the future development plans for property under development and other market factors. 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

49

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 pr operty 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).

Impairments of Land Held for Development

When demand for development declines and the ability to sell land held for development deteriorates, or other market factors indicate a possible impairment in the recoverability of land held for development, it is reviewed for impairment by comparing its fair value to its carrying value. If the estimated sales value is less than the carrying value, the carrying value is written down to its estimated fair value.

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 unconsolidated Real Estate Ventures, and subsequently adjusted for equity in earnings, cash contributions, 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 of consolidated debt 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. During the nine-month period ended September 30, 2018, no interest expense was capitalized. During the nine-month period ended September 30, 2017, we capitalized $0.4 million of interest expense.

On a periodic basis, management also assesses whether there are any indicators that the value of our investments in unconsolidated real estate ventures may be other than temporarily impaired. An investment is impaired only if the value of the investment, as estimated by management, is less than the carrying value of the investment and the decline is 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, as estimated by management. Estimates of value for each investment 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 our impairment analyses may not be realized.

RECENT PROPERTY TRANSACTIONS

Acquisitions

On June 29, 2018, we acquired, through a 99-year ground lease, the leasehold interest in a one-acre land parcel, located at 3025 JFK Boulevard, in Philadelphia, Pennsylvania. We prepaid $15.0 million of ground lease rent and capitalized $0.3 million of costs related to entering the lease. Additionally, the ground lease required us to pay $5.6 million for a leasehold valuation credit, which can be applied to increase the density of the projects subject to the Schuylkill Yards Project master development agreement. Of this deposit, $2.4 million must be applied to the development of 3001-3003 and 3025 JFK Boulevard. If we do not construct a minimum of 1.2 million square feet of floor area ratio (“FAR”) on these land parcels, the credit will not be realized. The remaining credit of $3.2 million can be used for development in excess of 1.2 million FAR at 3001-3003 and 3025 JFK Boulevard or toward future ground lease takedowns at the Schuylkill Yards Development Site. The deposit is reimbursed if the master development agreement is terminated by the landowner.

On March 22, 2018, we acquired, through a 99-year ground lease, the leasehold interest in a one-acre land parcel located at 3001-3003 JFK Boulevard, in Philadelphia, Pennsylvania. We prepaid $24.6 million of ground lease rent and capitalized $0.3 million of costs related to entering the lease.

On January 5, 2018, we acquired, from our then partner in each of the Four Tower Bridge real estate venture and the Seven Tower Bridge real estate venture, the partner’s 35% ownership interest in the Four Tower Bridge real estate venture in exchange for our 20% ownership interest in the Seven Tower Bridge real estate venture. As a result of this non-monetary exchange, we acquired 100% of the Four Tower Bridge real estate venture, which owns an office property containing 86,021 square feet, in Conshohocken, Pennsylvania, encumbered with $9.7 million in debt.

Our acquisition of the 35% ownership interest in Four Tower Bridge resulted in the consolidation of the property. As such, we capitalized $0.1 million of acquisition related costs and allocated the acquisition value, consisting of the fair value of $23.6 million and the acquisition related costs, to tangible and intangible assets.

Dispositions

We sold the following office property during the nine-month period ended September 30, 2018 (dollars in thousands):

(a) | As of March 31, 2018, we had not transferred control to the buyer of this land parcel, or two other parcels at this site which were sold during 2017, because of a completion guarantee which required us, as developer, to complete certain infrastructure improvements on behalf of the buyers of the land parcels. The cash received at settlement was recorded as “Deferred income, gains and rent” on our consolidated balance sheets. During the three months ended June 30, 2018, the infrastructure improvements were substantially completed, at which time we transferred control of the land parcels. As a result, we then recognized the sale. See Note 2, “Basis of Presentation,” to the consolidated financial statements for further discussion of the infrastructure improvements and related revenue recognition.

| (a) | As of September 30, 2018, we determined that the sale of eight office properties, containing 1,293,197 rentable square feet, in the Metropolitan Washington, D.C. segment, was probable and classified these properties as held for sale in accordance with applicable accounting standards for long lived assets. At such date, the $366.0 million carrying value of the properties exceeded the estimated $309.1 million fair value less the anticipated costs of sale. As a result, we recognized an impairment loss totaling approximately $56.9 million during the three-month period ended September 30, 2018. We measured this impairment based on a discounted cash flow analysis, using a hold period of ten years and residual capitalization rates and discount rates of 7.47% and 8.60%, respectively.

| (b) | As of September 30, 2018, we determined that the sale of one land parcel in the Pennsylvania Suburbs segment and two parcels of land in the Other segment was probable and classified these properties as held for sale in accordance with applicable accounting standards for long lived assets. At such date, the fair value less the anticipated costs of sale of the properties exceeded the carrying values. As a result, we expect to record gains on sale. The fair value measurement is based on the pricing in the purchase and sale agreements.

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

MAP Venture

On August 1, 2018, MAP Venture, in which we hold a 50% ownership interest, refinanced its $180.8 million third party debt financing, secured by the buildings of MAP Venture and maturing February 9, 2019, with $185.0 million third party debt financing, also secured by the buildings of the venture, bearing interest at LIBOR + 2.45% capped at a total maximum interest of 6.00% and maturing on August 1, 2023.

Brandywine 1919 Ventures

On June 26, 2018, we and our partner, LCOR/Calstrs, each provided a $44.4 million mortgage loan to Brandywine 1919 Ventures, an unconsolidated real estate venture in which we and LCOR/Calstrs each hold a 50% ownership interest. As a result, we recorded a related-party note receivable of $44.4 million in the “Other assets” caption on our consolidated balance sheets. The loan bears interest at a fixed 4.0% rate with a scheduled maturity on June 25, 2023. Brandywine 1919 Ventures used these proceeds to fund the $88.8 million repayment of its construction loan, which included $88.6 million in outstanding principal and $0.2 million of interest, on June 26, 2018.

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

52

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 ba ses its estimates and assumptions on historical experience and current economic conditions.

Our Annual Report on Form 10-K for the year ended December 31, 2017 contains a discussion of our critical accounting policies. There have been no significant changes in our critical accounting policies since December 31, 2017. See also Note 2, "Basis of Presentation," in our unaudited consolidated financial statements for the nine-month period ended September 30, 2018, set forth herein.

RESULTS OF OPERATIONS

The following discussion is based on our consolidated financial statements for the three- and nine-month periods ended September 30, 2018 and 2017. 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 our consolidated financial statements for a reconciliation of NOI to our consolidated net income as defined by GAAP.

Comparison of the Three-Month Periods Ended September 30, 2018 and September 30, 2017

The table below shows selected operating information for the “Same Store Property Portfolio” and the “Total Portfolio.” The Same Store Property Portfolio consists of 76 properties containing an aggregate of approximately 14.2 million net rentable square feet, and represents properties that we owned for the entire three-month periods ended September 30, 2018 and 2017. The Total Portfolio includes the effects of other properties that were either placed into service, acquired or redeveloped after January 1, 2017 and disposed of prior to September 30, 2018 or classified as held for sale as of September 30, 2018. 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 September 30, 2018 and 2017) 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 September 30, 2018 and 2017.

During the three months ended September 30, 2018, eight properties containing 1,293,197 rentable square feet, located in our Metropolitan Washington, D.C. segment, were removed from the Same Store Property Portfolio because they were classified as held for sale. The office component of FMC Tower at Cira Centre South, 1900 Market Street, and 933 First Avenue, which together contain an aggregate of 1.2 million rentable square feet, were added to the Same Store Property Portfolio. For detail of the properties comprising the Same Store Property Portfolio, as of December 31, 2017, see Item 2. “Properties” section of our Annual Report on Form 10-K for the year ended December 31, 2017.

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 increased by $10.2 million during the third quarter of 2018 compared to the third quarter of 2017, primarily attributable to:

| • | $8.2 million increase in the Same Store Property Portfolio due to the office component at FMC Tower, 1900 Market Street and 933 First Avenue generating positive cash rent growth as free rent converts to cash rent at these properties during the third quarter of 2018 compared to 2017;

54

| • | $2.1 million increase from Recently Completed/Acquired Properties for the third quarter of 2 018 compared to the third quarter of 2017 primarily related to the acquisition of Four Tower Bridge in January 2018 and the residential and retail components of FMC Tower being fully placed into service; and

| • | $1.1 million increase from Development/Redevelopment Properties, primarily attributable to Broadmoor Building 6, an office property located in the Austin, Texas segment, being partially placed into service subsequent to the third quarter of 2017 and One Drexel Plaza, an office property acquired during the fourth quarter of 2017.

The increase of $11.4 million was offset by a $1.2 million decrease due to the disposition of 15 properties from the third quarter of 2017 through the third quarter of 2018 (the “Q3 2017 through Q3 2018 Dispositions”). The Q3 2017 through Q3 2018 Dispositions include eight properties classified as held for sale at September 30, 2018.

Straight-line rents from the Total Portfolio decreased by $5.4 million from free rent converting to cash rent, of which $5.8 million related to the Same Store Property Portfolio due to the expiration of free rent periods for tenants within the office component at FMC Tower, 1900 Market Street and 933 First Avenue, net of other leasing activity that took place during the third quarter of 2018 and $0.1 million of which related to the Q3 2017 through Q3 2018 Dispositions. These decreases were offset by an increase of $0.5 million from the Development/Redevelopment Properties, primarily related to partial placement into service during the fourth quarter of 2017 of Broadmoor Building 6 and One Drexel Plaza, an office building acquired during the fourth quarter of 2017, both of which contain leases with free rent periods during the third quarter of 2018.

Tenant reimbursements from the Total Portfolio increased $3.3 million from the third quarter of 2017 to the third quarter of 2018, primarily attributable to an increase of $2.3 million from the Same Store Property Portfolio due to the expiration of free rent periods for tenants within the office component at FMC Tower, 1900 Market Street and 933 First Avenue during the third quarter of 2018, a $1.0 million increase from Development/Redevelopment Properties placed into service subsequent to the second quarter of 2017 and $0.1 million from Recently Completed/Acquired Properties. These increases were partially offset by a decrease of $0.1 million from the Q3 2017 through Q3 2018 Dispositions.

Third party management fees, labor reimbursement and leasing decreased by $2.0 million for the third quarter of 2018 compared to the third quarter of 2017, due primarily to decreases in third party management and development fees of $2.3 million. The decrease includes $1.6 million of construction management fees related to the Subaru Headquarters development, which was substantially complete as of December 31, 2017, $0.4 million of third party management fees related to the sale of eight office properties by the Austin Venture and $0.3 million related to the Q3 2017 sale of an office property held by our BDN – AI Venture. These decreases were partially offset by a $0.3 million increase in construction management fees at the MAP Venture.

Property Operating Expenses

Property operating expenses across our Total Portfolio increased $1.0 million for the third quarter of 2018 compared to the third quarter of 2017, of which $1.1 million relates to the Same Store Property Portfolio due to the office component at FMC Tower, 1900 Market Street and 933 First Avenue being placed into the Same Store Property Portfolio during the third quarter of 2018 and $0.8 million relates to Development/Redevelopment Properties, primarily because of the Broadmoor Building 6 being partially placed into service subsequent to June 30, 2017 and One Drexel Plaza, which was acquired during the fourth quarter of 2017 and $0.5 million of increases related to Recently Completed/Acquired Properties, primarily due to the acquisition of Four Tower Bridge in January 2018 and the residential and retail components of FMC Tower being fully placed into service. These increases were partially offset by a $1.1 million decrease related to the Q3 2017 through Q3 2018 Dispositions, $0.2 million from the Q4 2017 sale of eight office properties by the Austin Venture and $0.1 million from the Q3 2017 sale of 7101 Wisconsin Avenue, held by our BDN – AI Venture.

Real Estate Taxes

Real estate taxes increased $1.2 million for the third quarter of 2018 compared to the third quarter of 2017, of which $1.2 million relates to increased real estate tax assessments at the Same Store Property Portfolio, primarily in the Philadelphia CBD segment, $0.2 million related to Development/Redevelopment Properties and $0.1 million related to Recently Completed/Acquired Properties. These increases were partially offset by decreases of $0.3 million from the Q3 2017 through Q3 2018 Dispositions.

Depreciation and Amortization

Depreciation and amortization expense increased by $1.5 million for the third quarter of 2018 compared to the third quarter of 2017, of which $1.2 million of the increase relates to the Same Store Property Portfolio due to the office component at FMC Tower, 1900 Market Street and 933 First Avenue being placed into Same Store during the third quarter of 2018, a $1.1 million increase from Development/Redevelopment Properties, primarily relating to Broadmoor Building 6 being partially placed into service subsequent to the second quarter of 2017 and One Drexel Plaza which was acquired during the fourth quarter of 2017, and a $0.5 million increase

55

related to Recently Completed/Acquired Properties primarily related to the acquisition of Four Tower Bridge in January 2018 and the residential and retail components of FMC Tower being fully placed into service. These increases were offset by a decrease of $0.9 million from assets that were fully depreciated during the third quarter of 2017 in our Other segment and $0.4 million relating to the Q3 2017 through Q3 2018 Dispositions.

Provision for Impairment

As of September 30, 2018, we determined that the we would not recover the carrying value of eight held for sale properties in our Metropolitan Washington, D.C. segment and recorded an impairment charge of $56.9 million for the three months ended September 30, 2018. There were no impairment charges for the three months ended September 2017.

Interest Income

Interest income increased by $1.1 million from the third quarter of 2017 to the third quarter of 2018 due to interest income received from a note receivable associated with a mortgage loan provided to Brandywine 1919 Ventures during the second quarter of 2018. The increase is also a result of higher average cash balances and higher interest rates on money market funds during the three months ended September 30, 2018 compared to the three months ended September 30, 2017.

Interest Expense

Interest expense decreased $0.5 million from the third quarter of 2017 to the third quarter of 2018 primarily due to the following:

| • | $4.2 million decrease related to the early retirement of the 4.95% Guaranteed Notes due 2018 during the fourth quarter of 2017;

| • | $1.2 million decrease related to interest expense incurred related to the Credit Facility, which had no balance during the third quarter of 2018 compared to an outstanding balance of $178.0 million as of September 30, 2017; and

| • | $0.5 million increase in capitalized interest, due to an increase in development/redevelopment activity during the third quarter of 2018 compared to the third quarter of 2017.

The decrease of $5.9 million in interest expense described above was offset by the following:

| • | $4.5 million increase related to the issuance of the 3.95% Guaranteed Notes due 2027 on November 17, 2017; and

| • | $0.9 million increase related to the issuance of an additional $100.0 million of 3.95% Guaranteed Notes due 2023 on November 17, 2017.

Equity in income (loss) of real estate ventures

Equity in income (loss) of unconsolidated real estate ventures increased $5.7 million from the third quarter of 2017 to the third quarter of 2018 primarily due to the following:

| • | $4.8 million due to an other than temporary impairment charge at the Brandywine AI Venture during the third quarter of 2017, with no such impairment during the third quarter of 2018;

| • | $0.5 million increase from the Austin Venture, primarily driven by the sale of eight office properties during the fourth quarter of 2017 that were not accretive to equity in income; and

| • | $0.3 million decrease in equity in losses at the MAP Venture, primarily driven by a 2.45% LIBOR spread on debt, which was lowered from a 6.25% LIBOR spread on debt from the refinance of debt during the third quarter of 2018.

Net Gain on Sale of Undepreciated Real Estate

The gain of $1.0 million recognized during the third quarter of 2017 resulted from the dispositions of Bishop’s Gate land and 50 E. Swedesford Square, which generated gains of $0.1 million and $0.9 million, respectively. There was no comparable activity for the third quarter of 2018.

Net Gain on Real Estate Venture Transactions

The gain of $13.8 million recognized during the third quarter of 2017 resulted from the disposition of an office property at 7101 Wisconsin Avenue, located in Bethesda, Maryland, held by the BDN – AI Venture. There was no comparable activity for the third quarter of 2018.

56

Income Tax Benefit

The income tax benefit of $0.8 million during the third quarter of 2017 resulted from operating losses at the residential component of FMC Tower prior to its stabilization. There was no change to our income tax position during the third quarter of 2018.

Net Income (Loss)

Net income decreased by $62.3 million from the third quarter of 2017 to the third quarter of 2018 as a result of the factors described above.

Net Income (Loss) per Common Share – fully diluted

Net loss per share was ($0.24) for the third quarter of 2018 as compared to net income per share of $0.11 for the third quarter of 2017 as a result of the factors described above.

Comparison of the Nine-Month Periods Ended September 30, 2018 and September 30, 2017

The table below shows selected operating information for the “Same Store Property Portfolio” and the “Total Portfolio.” The Same Store Property Portfolio consists of 73 properties containing an aggregate of approximately 13.0 million net rentable square feet, and represents properties that we owned for the entire nine-month periods ended September 30, 2018 and 2017. The Total Portfolio includes the effects of other properties that were either placed into service, acquired or redeveloped after January 1, 2017 and disposed of prior to September 30, 2018 or classified as held for sale as of September 30, 2018. 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 nine-month periods ended September 30, 2018 and 2017) by providing information for the properties which were acquired, placed into service, under development or redevelopment and administrative/elimination information for the nine-month periods ended September 30, 2018 and 2017.

During the nine months ended September 30, 2018, the Same Store Property Portfolio was reduced by the disposition of 20 East Clementon Road, an office property in Gibbsboro, New Jersey, containing 38,260 rentable square feet and The Lift at Juniper Street, a parking garage containing no rentable square feet, which was removed from the Same Store Property Portfolio and placed into redevelopment. Additionally, eight properties containing 1,293,197 rentable square feet, located in Herndon, Virginia, were removed from the Same Store Property Portfolio because they were classified as held for sale. For detail of the properties comprising the Same Store Property Portfolio, as of December 31, 2017, see Item 2. “Properties” section of our Annual Report on Form 10-K for the year ended December 31, 2017.

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 increased by $25.5 million during the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017, primarily attributable to:

| • | $25.9 million increase from Recently Completed/Acquired Properties for nine months ended September 30, 2018 compared to the nine months ended September 30, 2017 primarily related to the expiration of free rent periods for tenants within the FMC Tower;

| • | $4.4 million increase in the Same Store Property Portfolio due to positive cash rent growth and free rent converting to cash rent, primarily in the Philadelphia CBD segment, during the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017; and

58

| • | $2.0 million increase from Development/Redevelopment Properties, primarily att ributable to Broadmoor Building 6, an office property located in the Austin, Texas segment, being partially placed into service during the fourth quarter of 2017 and One Drexel Plaza, an office property acquired during the fourth quarter of 2017.

The increase of $32.3 million was offset by a $6.8 million decrease due to the disposition of 29 properties from the nine months ended September 30, 2017 through the nine months ended September 30, 2018 (the “YTD 2017 and 2018 Dispositions”). The YTD 2017 and 2018 Dispositions include eight properties classified as held for sale at September 30, 2018.

Straight-line rents from the Total Portfolio decreased by $11.4 million from free rent converting to cash rent, of which $7.8 million related to Recently Completed/Acquired Properties, primarily the FMC Tower, which is located in the Philadelphia CBD segment and $5.2 million in the Same Store Property Portfolio, primarily the Philadelphia CBD segment. These decreases in straight-line rent are net of other leasing activity at the Recently/Completed/Acquired Properties and Same Store Property Portfolio. These decreases were offset by a $1.5 million increase from Development/Redevelopment Properties, primarily related to Broadmoor Building 6 being partially placed into service during the fourth quarter of 2017 and One Drexel Plaza, which was acquired during the fourth quarter of 2017, both of which contain new leases which include free rent periods and a $0.2 million decrease from the YTD 2017 and 2018 Dispositions.

Tenant reimbursements from the Total Portfolio increased $5.3 million from the nine months ended September 30, 2017 to the nine months ended September 30, 2018, due to an increase of $3.0 million from Recently Completed/Acquired Properties due to the expiration of free rent periods for tenants within the FMC Tower, a $2.5 million increase from Development/Redevelopment Properties, relating to Broadmoor Building 6 being partially placed into service during the fourth quarter of 2017 and One Drexel Plaza, which was acquired during the fourth quarter of 2017, and an increase of $1.8 million in the Same Store Property Portfolio, which trended along with the increase in operating expenses over the same period. These increases were partially offset by a decrease of $1.8 million from the YTD 2017 and 2018 Dispositions.

Third party management fees, labor reimbursement and leasing decreased by $3.0 million for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017, primarily due to decreases in third party management and development fees of $6.1 million. The decrease includes $3.5 million of construction management fees relates to the Subaru Headquarters development, which was substantially complete as of December 31, 2017, $2.1 million of third party management fees relates to the sale of eight office properties by the Austin Venture and $0.5 million related to the Q3 2017 sale of an office property held by our BDN – AI Venture. These decreases were offset by a $3.1 million increase in construction management fees, primarily relating to the MAP Venture.

Other income increased $1.9 million, which was primarily related to restaurant income from Walnut Street Café at the FMC Tower, which was placed into service at the end of the second quarter of 2017.

Property Operating Expenses

Property operating expenses across our Total Portfolio increased $4.1 million for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017, of which $5.4 million relates to Recently Completed/Acquired Properties, primarily the FMC Tower which was fully placed into service during the second quarter of 2017. Development/Redevelopment Properties increased $2.7 million, primarily because of the Broadmoor Building 6 being partially placed into service subsequent to September 30, 2017 and One Drexel Plaza, which was acquired during the fourth quarter of 2017. The Same Store Portfolio increased $2.1 million, primarily related to our Philadelphia CBD segment. These increases were partially offset by a $4.5 million decrease related to the YTD 2017 and 2018 Dispositions and $1.1 million in salary expense reductions relating from the sale of properties from unconsolidated real estate ventures that we manage and a $0.5 million reduction in development salary expenses due to increased capitalization at our development/redevelopment projects.

Real Estate Taxes

Real estate taxes increased $3.2 million for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017, of which $3.2 million relates to increased real estate tax assessments at the Same Store Property Portfolio, primarily in the Philadelphia CBD segment, $0.9 million related to Recently Completed/Acquired Properties and $0.5 million related to Development/Redevelopment Properties. These increases were partially offset by decreases of $1.4 million from the YTD 2017 and 2018 Dispositions.

Depreciation and Amortization

Depreciation and amortization expense decreased by $1.7 million for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017, of which $5.2 million of the decrease relates to fully amortized intangible assets at the Same Store Property Portfolio, which is directly attributable to a reduction in intangible asset amortization related to the Broadmoor portfolio,

59

located in our Austin, Texas segment which was acquired during Q2 2015, a $1.9 million decrease relates to the YTD 2017 and 2018 Dispositions and a $0.9 million decr ease relates to assets that were fully depreciated during the third quarter of 2017. These decreases were offset by a $3.2 million increase from Development/Redevelopment Properties, primarily relating to Broadmoor Building 6 being partially placed into se rvice during the fourth quarter of 2017 as well as One Drexel Plaza, which was acquired during the fourth quarter of 2017 and a $3.1 million increase in depreciation expense from Recently Completed/Acquired Properties, primarily relating to the office comp onent of FMC Tower being fully placed into service during the second quarter of 2017 as well as Four Tower Bridge, which was acquired in January 2018.

Provision for Impairment

As of September 30, 2018, we determined that the we would not recover the carrying value of eight held for sale properties in our Metropolitan Washington, D.C. segment and recorded an impairment charge of $56.9 million for the three months ended September 30, 2018.

As of June 30, 2017, we determined that we would not recover the carrying value of one land parcel, consisting of 50 acres, in the Other segment. Accordingly, we recorded an impairment charge of $0.3 million at June 30, 2017.

As of December 31, 2016, based on our held for sale impairment analysis, we determined that we would not recover the carrying value of three office properties located in the Metropolitan Washington D.C. segment. Because we determined that the carrying value of these properties exceeded their fair value, a $2.6 million impairment charge was recorded. Subsequent to our December 31, 2016 impairment review, there was a purchase price reduction of $1.7 million under the agreement of sale, which resulted in an additional impairment charge of $1.7 million during the quarter ended March 31, 2017.

As of March 31, 2017, based on our held for use impairment analysis, we determined that we would not recover the carrying value of four office properties located in the Other segment. Because we determined that the carrying value of these properties exceeded their fair value, a $1.0 million impairment charge was recorded.

Interest Income

Interest income increased by $1.9 million from the nine months ended September 30, 2017 to the nine months ended September 30, 2018 due to interest income received from a note receivable associated with a mortgage loan provided to Brandywine 1919 Ventures during the second quarter of 2018. The increase is also a result of higher average cash balances and higher interest rates on money market funds from the nine months ended September 30, 2017 to the nine months ended September 30, 2018.

Interest Expense

Interest expense decreased $3.4 million from the nine months ended September 30, 2017 compared to the nine months ended September 30, 2018 primarily due to the following:

| • | $12.5 million decrease related to the early retirement of the 4.95% Guaranteed Notes due 2018 during the fourth quarter of 2017;

| • | $5.7 million decrease related to the repayment of the 2017 Unsecured Notes on May 1, 2017; and

| • | $2.0 million decrease related to interest expense incurred related to the Credit Facility, which had no balance during the nine months ended September 30, 2018 compared to an outstanding balance of $178.0 million as of September 30, 2017.

The decrease of $20.2 million in interest expense described above was offset by the following:

| • | $13.5 million increase related to the issuance of the 3.95% Guaranteed Notes due 2027 on November 17, 2017;

| • | $2.6 million increase related to the issuance of an additional $100.0 million of 3.95% Guaranteed Notes due 2023 on November 17, 2017;

| • | $0.4 million decrease in capitalized interest as the FMC Tower has been fully placed into service; and

| • | $0.3 million increase in variable interest expense related to our Trust Indenture IA compared to the nine months ended September 30, 2017.

60

Equity in loss of real estate ventures

Equity in loss of unconsolidated real estate ventures increased $4.2 million from the nine months ended September 30, 2017 to the nine months ended September 30, 2018 primarily due to the following:

| • | $4.8 million due to an other than temporary impairment charge at the Brandywine AI Venture during the third quarter of 2017, with no such impairment during the third quarter of 2018; and

| • | $0.6 million decrease in equity in losses incurred at the MAP Venture, primarily driven by a decrease in interest expense due to the refinancing of its third party debt, on August 1, 2018, which resulted in a 380 basis point decrease in the borrowing spread over LIBOR.

These decreases were offset by a $0.8 million decrease from the sale of the evo at Cira Venture during the first quarter of 2018 and a $0.3 million decrease from the Four and Seven Tower Bridge transaction, which resulted in the acquisition of the office property held by the Four Tower Bridge Venture, during the first quarter of 2018.

Net Gain (Loss) on Disposition of Real Estate

The immaterial loss on disposition of real estate for the nine months ended September 30, 2018 resulted from the disposition of the office property at 20 East Clementon Road, in Gibbsboro, New Jersey.

The net gain on disposition of real estate of $8.4 million recognized in the nine months ended September 30, 2017 resulted from a gain of $0.5 million on the sale of two office properties located in Concord, California, a gain of $6.5 million from the sale of the Marine Piers located in Philadelphia, Pennsylvania, an additional $0.5 million gain recognized on Cira Square, which was disposed of in the first quarter of 2016, and a gain of $1.4 million on the sale of the retail property at 7000 Midlantic in Mount Laurel, New Jersey. These gains were partially offset by a loss of $0.2 million, representing closing costs, on the sale of three office properties located in Cherry Hill, New Jersey and a loss of $0.3 million, representing closing costs, on the sale of four office properties located in Marlton, New Jersey known as the Evesham Corporate Center.

Net Gain on Sale of Undepreciated Real Estate

The gain of $1.0 million recognized during the nine months ended September 30, 2017 resulted from the dispositions of Bishop’s Gate land and 50 E. Swedesford Square, which generated gains of $0.1 million and $0.9 million, respectively.

Net Gain from Real Estate Venture Transactions

The $37.3 million net gain from Real Estate Venture transactions during the nine months ended September 30, 2018 relates to the following:

| • | $25.7 million from the sale of the evo at Cira Centre South Venture; and

| • | $11.6 million gain recognized on the exchange of our 20% interest in the Seven Tower Bridge Venture for the remaining 35% interest in the Four Tower Bridge Venture.

The $28.3 million gain recognized during the nine months ended September 30, 2017 resulted from a $13.7 gain on the disposition of an office property at 7101 Wisconsin Avenue, located in Bethesda, Maryland, held by the BDN – AI Venture, and a $14.6 million gain on the sale of our entire 50% interest in TB-BDN Plymouth Apartments, L.P.

Income Tax (Provision) Benefit

The $1.2 million decrease in income tax benefit from the nine months ended September 30, 2017 to the nine months ended September 30, 2018 was primarily related to operating losses at the residential component of FMC Tower prior to its stabilization.

Net Income

Net income decreased by $33.4 million from the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017 as a result of the factors described above.

61

Net Income per Common Share – fully diluted

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 common share repurchases.

As of September 30, 2018, the Parent Company owned a 99.2% interest in the Operating Partnership. The remaining interest of approximately 0.8% 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 2018 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 revolving 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 revolving credit facility, including unsecured term loans and unsecured notes. As of September 30, 2018 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 revolving 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. In light of the 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 loan would increase.

The Parent Company unconditionally guarantees the Operating Partnership’s secured and unsecured obligations, which, as of September 30, 2018, amounted to $324.9 million and $1,628.6 million, respectively.

62

Capital Markets

The Parent Company 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 Parent Company maintains 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 (the “Offering Program”) that permits us to sell up to 16,000,000 common shares in “at the market” offerings as defined in Rule 415 of the Securities Act until January 10, 2020. From initial sales activity under the Offering Program on December 13, 2017 through September 30, 2018, we generated approximately $51.6 million from the issuance of 2,882,302 common shares under the Offering Program at an average price per share of $18.19 after payment of approximately $0.8 million of commissions to the sales agents and before offering expenses. During the three months ended September 30, 2018, we did not sell any shares under the Offering Program. At September 30, 2018, 13,117,698 common shares remained available for future sale under the Offering Program.

The Parent Company maintains a share repurchase program under which the Board of Trustees has authorized the Parent Company to repurchase common shares 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. We expect to fund any share repurchases with a combination of available cash balances and availability under our unsecured revolving credit facility. As of September 30, 2018, 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 we determine from time to time. 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 nine months ended September 30, 2018 or the nine months ended September 30, 2017.

2018 Credit Facility

On July 17, 2018, we executed the Amended and Restated Revolving Credit Agreement (as amended and restated, the “2018 Credit Facility”). The amendment and restatement, among other things: (i) maintained the total commitment of the revolving line of credit of $600.0 million; (ii) extended the maturity date from May 15, 2019 to July 15, 2022, with two six-month extensions at our election subject to specified conditions and subject to payment of an extension fee; (iii) reduced the interest rate margins applicable to Eurodollar loans; (iv) provided for an additional interest rate option based on a floating LIBOR rate; and (v) removed the covenant requiring us to maintain a minimum net worth. In connection with the amendments, we capitalized $2.7 million in financing costs, which will be amortized through the July 15, 2022 maturity date.

At the our option, loans outstanding under the 2018 Credit Facility will bear interest at a rate per annum equal to (1) LIBOR plus between 0.775% and 1.45%, based on the our credit rating, or (2) a base rate equal to the greatest of (a) the Administrative Agent's prime rate, (b) the Federal Funds rate plus 0.5% or (c) LIBOR for a one month period plus 1.00%, in each case, plus a margin ranging from 0.0% to 0.45% based on the our credit rating. The 2018 Credit Facility also contains a competitive bid option that allows banks that are part of the lender consortium to bid to make loan advances to us at a reduced interest rate. In addition, we are also obligated to pay (1) in quarterly installments a facility fee on the total commitment at a rate per annum ranging from 0.125% to 0.30% based on our credit rating and (2) an annual fee on the undrawn amount of each letter or credit equal to the LIBOR Margin. Based on our current credit rating, the LIBOR margin is 1.10% and the facility fee is 0.25%.

Capital Recycling

The Operating Partnership also considers net sales of selected properties and recapitalization of unconsolidated real estate ventures as additional sources of managing its liquidity. During the nine months ended September 30, 2018, we sold 19.7 acres of land and one office property for aggregate net cash proceeds of $14.9 million and $2.0 million, respectively. Also during the nine months ended September 30, 2018, we sold our entire 50% partnership interest in an unconsolidated real estate venture for net cash proceeds of $43.0 million.

63

Our primary uses of capital will be to fund the completion of our current development and redevelopment projects. With approximately $70.4 million of cash and cash equivalents and $598.1 million of available borrowings under our 2018 Credit Facility, net of $1.9 million in letters of credit outstanding as well as cash flows from operations net of dividend requirements, we believe we have sufficient capital to complete these projects. We believe that our liquidity, including t he availability under our 2018 Credit Facility, and proceeds from debt financings and asset sales provide sufficient liquidity to fund our remaining capital requirements on existing development and redevelopment projects and pursue additional attractive in vestment opportunities.

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 September 30, 2018 and December 31, 2017, we maintained cash and cash equivalents and restricted cash of $71.2 million and $203.4 million, respectively. The following are the changes in cash flow from our activities for the nine-month periods ended September 30, 2018 and 2017 (in thousands):

|  | Nine Months Ended September 30, |
Activity |  | 2018 |  |  | 2017 |
Operating |  | $ | 154,537 |  |  | $ | 128,349 |
Investing |  |  | (180,576 | ) |  |  | 17,545 |
Financing |  |  | (106,218 | ) |  |  | (313,960 | )
Net cash flows |  | $ | (132,257 | ) |  | $ | (168,066 | )

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.

The net increase of $26.2 million in cash from operating activities for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017 is primarily due to free rent periods ending in our Philadelphia CBD segment.

The net decrease of $198.1 million in cash from investing activities during the nine months ended September 30, 2018 to the nine months ended September 30, 2017 primarily relates to property portfolio repositioning efforts, which began to wind down in 2017. Quantitatively, the decrease resulted from the following:

| • | $98.2 million decrease in net proceeds from the disposition of two land parcels and an office building during the nine months ended September 30, 2018 compared to the sale of 14 properties and five land parcels during the nine months ended September 30, 2017;

| • | $44.4 million decrease from the 2018 issuance of a mortgage loan to 1919 Ventures;

| • | $22.6 million decrease in cash from increased capital expenditures for tenant improvements, developments/redevelopments and leasing commissions, which primarily relates to ongoing development and redevelopment projects;

| • | $16.1 million decrease in proceeds from real estate venture sales as a result of the proceeds of $43.0 million from the sale of the evo at Cira Centre South Venture during the nine months ended September 30, 2018 compared to $59.0 million in proceeds from the sales of the TB-BDN Plymouth Apartments, L.P. (referred to as the “Parc at Plymouth Meeting Venture”) and 7101 Wisconsin Avenue from the BDN – AI Venture during the nine months ended September 30, 2017;

| • | $9.8 million decrease in cash distributed from unconsolidated Real Estate Ventures in excess of cumulative equity in income;

| • | $6.2 million decrease primarily from deposits for real estate relating to our ability to increase project density at certain of the development sites within Schuylkill Yards (See Note 3, “Real Estate Investments” to our Consolidated Financial Statements for further details); and

| • | $5.5 million decrease in cash from the 2018 acquisitions of 3001-3003 JFK Boulevard and 3025 JFK Boulevard in Philadelphia, Pennsylvania compared to the purchase of 3000 Market Street in Philadelphia, Pennsylvania and a deferred payment on the acquisition of 2100 Market Street in Philadelphia, Pennsylvania during 2017.

The decrease in cash provided by investing activities was primarily offset by a $4.6 million decrease in investment in unconsolidated Real Estate Ventures.

64

The net decrease of $207.7 million in cash used in financing activities for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017 is attributed to the following:

| • | $300.0 million for the repayment of the entire principal balance of the unsecured 5.70% Guaranteed Notes upon maturity on May 1, 2017, with no comparable repayments during 2018;

| • | $100.0 million from the redemption of our outstanding 6.900% Series E Preferred Shares at par during the nine months ended September 30, 2017; and

| • | $0.4 million from the issuance of common shares under at-the-market offerings during 2018, with no comparable activity during 2017.

The decreases of $400.4 million in cash used in financing activities was offset by $192.6 million related to the following;

| • | $178.0 million in net borrowings under the unsecured revolving credit facility during the nine months ended September 30, 2017;

| • | $8.6 million increase in cash used due to the increase of dividends paid from $0.16 per share during the nine months ended September 30, 2017 to $0.18 per share for the nine months ended September 30, 2018;

| • | $2.7 million increase in cash used for debt financing costs paid due to the refinance of the unsecured revolving credit facility;

| • | $1.3 million increase from the repayment of mortgage notes payable;

| • | $1.2 million in proceeds from the exercise of stock options during the nine months ended September 30, 2017, with no such activity for the nine months ended September 30, 2018; and

| • | $0.8 million increase in shares used for employee taxes upon vesting of share awards.

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 September 30, 2018.

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 indebtedness as it matures, subject to tax guarantees, 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.

Equity

On September 11, 2018, the Parent Company declared a distribution of $0.18 per common share, totaling $32.5 million, which it paid on October 18, 2018 to its shareholders of record as of October 4, 2018. 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 year or stop 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.

The above table does not include amounts related to the 4040 Wilson development in Arlington, Virginia. For further discussion of this development, see Item 1. “Business – Developments,” included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 and section “Overview – Development Risk,” above, for further details.

We provide customary guarantees for certain development projects of our unconsolidated real estate ventures. See Note 4, "Investment in Unconsolidated Real Estate Ventures," and Note 13, “Commitments and Contingencies,” to the consolidated financial statements for further details on payment guarantees provided on the behalf of real estate ventures.

As of September 30, 2018, we expect to incur $22.1 million for capital improvements to operating properties, which are not included in the above table. We expect that most of these improvements will be paid by September 30, 2020.

On October 13, 2017, we acquired a leasehold interest in the office building known as One Drexel Plaza, in Philadelphia, Pennsylvania. In connection with the acquisition, we are required to spend no less than $8.0 million in capital improvements to the property. Funding related to this requirement had not yet begun as of September 30, 2018. As the timing of the capital improvements has not yet been determined, these costs are not included in the above table within the ‘Development contracts’ caption. See Note 13, “Commitments and Contingencies,” to the consolidated financial statements for further information.

During the fourth quarter of 2017, in connection with the Schuylkill Yards Project, we entered into a neighborhood engagement program and, as of September 30, 2018, had $2.7 million of future contractual obligations, which are included in the table above within the ‘Development contracts’ caption. In addition, we estimate $0.7 million of potential additional contributions for which we are not currently contractually obligated. As such, these costs are not included in the above table. See Note 13, “Commitments and Contingencies,” to the consolidated financial statements for further information.

On July 1, 2016, we closed on the acquisition of 34.6 acres of land located in Austin, Texas known as the Garza Ranch for a purchase price of $20.6 million. As of September 30, 2018, we sold three parcels containing 8.4 acres, 1.7 acres and 6.6 acres (of the 34.6 acres) to three unaffiliated third parties. In connection with the agreements of sale, we entered into a development agreement and related completion guarantee to construct certain infrastructure improvements to the land. These improvement costs were included in the sale price of each land parcel. Recognition of the sale of the land parcels was deferred until the improvements were substantially completed. See Note 2, “Basis of Presentation,” to the consolidated financial statements for further discussion of the infrastructure improvements and related revenue recognition.

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 real estate 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 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 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 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.

The following table presents a reconciliation of net income attributable to common unit holders to FFO for the three- and nine-month periods ended September 30, 2018 and 2017:

(b) | Includes common share and partnership units outstanding through the three and nine months ended September 30, 2018 and 2017, respectively.

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

68

financial markets may affect the spread between our yield on invested assets and cost of funds and, in turn, our ability to make dis tributions 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 w hich 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 September 30, 2018, our consolidated debt consisted of mortgage loans with an outstanding principal balance of $324.9 million and unsecured notes with an outstanding principal balance of $1,300.0 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, except for one trust preferred security with an outstanding principal balance of $27.1 million. 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 financial position, but has no impact on interest incurred or cash flows. A change in interest rates on the variable portion of the debt portfolio impacts the interest incurred and cash flows, but does not impact the net financial 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 $10.1 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 $10.5 million.

As of September 30, 2018, based on prevailing interest rates and credit spreads, the fair value of our unsecured notes was $1,249.2 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 $12.4 million at September 30, 2018.

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 September 30, 2018. The total fair value of our debt was approximately $310.6 million and $308.9 million at September 30, 2018 and December 31, 2017, respectively. 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 $15.8 million at September 30, 2018. If market rates of interest decrease by 100 basis points the fair value of our outstanding variable rate debt would increase by approximately $17.2 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.
