EXPLANATORY NOTE
This report combines the quarterly reports on Form 10-Q for the period ended June 30, 2020 of Brandywine Realty Trust (the “Parent Company”) and Brandywine Operating Partnership L.P. (the “Operating Partnership”). The Parent Company is a Maryland real estate investment trust, or REIT, that owns its assets and conducts its operations through the Operating Partnership, a Delaware limited partnership, and subsidiaries of the Operating Partnership. The Parent Company, the Operating Partnership and their consolidated subsidiaries are collectively referred to in this report as the “Company”. In addition, as used in this report, terms such as “we”, “us”, and “our” may refer to the Company, the Parent Company, or the Operating Partnership.
The Parent Company is the sole general partner of the Operating Partnership and, as of June 30, 2020, owned a 99.4% interest in the Operating Partnership. The remaining 0.6% 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:

• | 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 contributing the net proceeds of such issuances to the Operating Partnership) and guaranteeing the debt obligations of the Operating Partnership. The Operating Partnership holds substantially all the assets of the Company, including the Company's ownership interests in the real estate ventures described below. 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.
To help investors understand the significant differences between the Parent Company and the Operating Partnership, this report presents the following as separate notes or sections for each of the Parent Company and the Operating Partnership:

• | Consolidated Financial Statements; and

Table of Contents

• | 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
Brandywine Realty Trust (the "Parent Company") is a self-administered and self-managed real estate investment trust (“REIT”) engaged in the acquisition, development, redevelopment, ownership, management, and operation of a portfolio of office and mixed-use properties.

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 June 30, 2020, the results of its operations for the three and six months ended June 30, 2020 and 2019 and its cash flows for the six months ended June 30, 2020 and 2019. The results of operations for such interim periods are not necessarily indicative of the results for a full year. These consolidated financial statements should be read in conjunction with the Parent Company’s and the Operating Partnership’s consolidated financial statements and footnotes included in their combined 2019 Annual Report on Form 10-K filed with the SEC on March 2, 2020.
The consolidated balance sheet at December 31, 2019 has been derived from the audited financial statements as of that date but does not include all the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements.

Table of Contents
The Company's Annual Report on Form 10-K for the year ended December 31, 2019 contains a discussion of our significant accounting policies under Note 2, "Summary of Significant Accounting Policies". There have been no significant changes in our significant accounting policies since December 31, 2019.
Risks and Uncertainties - COVID-19
Currently, one of the most significant risks and uncertainties is the potential adverse effect of the ongoing global COVID-19 pandemic, which has significantly slowed global economic activity, caused significant volatility in financial markets, and resulted in unprecedented job losses, causing many to fear an imminent global recession. The responses of many countries, including the U.S., have included mandatory quarantines, restrictions on business activities, including construction activities, restrictions on group gatherings, restrictions on travel and mandatory closures. These actions are creating disruption in the global economy and supply chains and adversely impacting many industries, including owners and developers of real estate. Moreover, there is significant uncertainty around the breadth and duration of business disruptions related to COVID-19, as well as its impact on the U.S. economy and consumer confidence. Demand for space at our properties is dependent on a variety of macroeconomic factors, such as employment levels, interest rates, changes in stock market valuations, rent levels and availability of competing space. The extent to which COVID-19 impacts our results will depend on future developments, many of which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of COVID-19 and the actions taken to contain it or treat its impact. The COVID-19 pandemic has caused continued negative economic impacts, market volatility, and business disruption, which could negatively impact our tenants’ ability to pay rent, our ability to lease vacant space, and our ability to complete development and redevelopment projects, and these consequences, in turn, could materially impact our results of operations.
Accounting Standards Updates
On April 10, 2020, the Financial Accounting Standards Board (the "FASB") issued a Staff Q&A to respond to some frequently asked questions about accounting for lease concessions related to the effects of the COVID-19 pandemic. Consequently, for concessions related to the effects of the COVID-19 pandemic, an entity will not have to analyze each contract to determine whether enforceable rights and obligations for concessions exist in the contract and can elect to apply or not apply the lease modification guidance to those contracts. Entities may make the elections for any lessor-provided concessions related to the effects of the COVID-19 pandemic (e.g., deferrals of lease payments, cash payments made to the lessee, reduced future lease payments) as long as the concession does not result in a substantial increase in the rights of the lessor or the obligations of the lessee. The Company has elected to account for lease concessions as though the enforceable rights and obligations for the concessions existed in the original lease. To date, the impact of lease concessions granted has not had a material effect on the financial statements. The Company will continue to evaluate the impact of lease concessions and the appropriate accounting for those concessions.
In March 2020, the FASB issued ASU 2020-04 Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments provide practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance is optional and is effective between March 12, 2020 and December 31, 2022. The guidance may be elected over time as reference rate reform activities occur. The Company continues to evaluate the impact of the guidance and may apply elections as applicable as additional changes in the market occur.
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments Credit Losses (Topic 326), which changes how entities measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance replaces the current incurred loss model with an expected loss approach, resulting in more timely recognition of such losses. In November 2018, the FASB released ASU 2018-19, Codification Improvements to Topic 326, Financial Instrument - Credit Losses, which clarifies that receivables arising from operating leases are not within the scope of Subtopic 326-20. The guidance was effective for the Company as of January 1, 2020. The Company adopted ASU 2016-13 effective January 1, 2020 and it did not have a material impact on the consolidated financial statements.

In addition, certain acquisition, transaction and other costs may not be reflected in the net assets at the real estate venture level.

(a) | The properties encumbered by these mortgages were classified as held for sale as of June 30, 2020 and, given that these debt obligations will remain with the properties after the transaction, they are included in "Liabilities related to assets held for sale, net" on the consolidated balance sheets as of June 30, 2020.

In addition to the debt described above, the Company utilizes borrowings under its unsecured revolving credit facility (the “Unsecured Credit Facility”) for general business purposes, including to fund costs of acquisitions, developments and redevelopments of properties, fund share repurchases and repay other debt. The Unsecured Credit Facility provides for borrowings of up to $600.0 million and the per annum variable interest rate on borrowings is LIBOR plus 1.10%. The interest rate and facility fee are subject to adjustment upon a change in the Company’s unsecured debt ratings. During the six months ended June 30, 2020, the weighted-average interest rate on Unsecured Credit Facility borrowings was 1.6% resulting in a nominal amount of interest expense. As of June 30, 2020, the effective interest rate on Unsecured Credit Facility borrowings was 1.3%.
The Parent Company unconditionally guarantees the unsecured debt obligations of the Operating Partnership (or is a co-borrower with the Operating Partnership) but does not by itself incur unsecured indebtedness. The Parent Company has no material assets other than its investment in the Operating Partnership.
The Company was in compliance with all financial covenants as of June 30, 2020. Certain of the covenants restrict the Company’s ability to obtain alternative sources of capital.

8. FAIR VALUE OF FINANCIAL INSTRUMENTS
Financial assets and liabilities recorded on the consolidated balance sheets are categorized based on the inputs to the valuation techniques as follows:

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

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

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

The Company determined the fair values disclosed below using available market information and discounted cash flow analyses as of June 30, 2020 and December 31, 2019, respectively. The discount rate used in calculating fair value is the sum of the current risk free rate and the risk premium on the date of measurement of the instruments or obligations. Considerable judgment is necessary to interpret market data and to develop the related estimates of fair value. Accordingly, the estimates presented are not necessarily indicative of the amounts that the Company could realize upon disposition. The use of different estimates and valuation methodologies may have a material effect on the fair value amounts shown. The Company believes that the carrying amounts reflected in the consolidated balance sheets at June 30, 2020 and December 31, 2019 approximate the fair values for cash and cash equivalents, accounts receivable, other assets and liabilities, accounts payable and accrued expenses because they are short-term in duration. The following are financial instruments for which the Company’s estimates of fair value differ from the carrying amounts (in thousands):

| June 30, 2020 |  | December 31, 2019
| Carrying Amount (a) |  | Fair Value |  | Carrying Amount (a) |  | Fair Value
Unsecured notes payable | $ | 1,503,164 |  |  | $ | 1,548,735 |  |  | $ | 1,503,435 |  |  | $ | 1,591,830 |
Variable rate debt | $ | 388,433 |  |  | $ | 369,356 |  |  | $ | 327,171 |  |  | $ | 309,947 |
Mortgage notes payable | $ | 310,155 |  |  | $ | 332,553 |  |  | $ | 313,812 |  |  | $ | 317,031 |
Notes receivable | $ | 44,430 |  |  | $ | 47,661 |  |  | $ | 44,430 |  |  | $ | 43,322 |

(a) | Net of deferred financing costs of $7.9 million and $8.7 million for unsecured notes payable, $1.2 million and $1.4 million for variable rate debt and $0.2 million for mortgage notes payable as of both June 30, 2020 and December 31, 2019.

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 related party note receivable of $44.4 million within 'Other assets' on the consolidated balance sheets. Refer to Note 4, ''Investment in Unconsolidated Real Estate Ventures" to

Table of Contents
the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 for further detail regarding this financing.
The Company used quoted market prices as of June 30, 2020 and December 31, 2019 to value the unsecured notes payable and, as such, categorized them as Level 2.
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 determined using a discounted cash flow model that considered borrowing rates available to the Company for loans with similar terms and characteristics. The fair value of the mortgage notes payable was determined using a discounted cash flow model that considered the contractual interest and principal payments discounted at 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.
The inputs utilized to determine fair value of the Company's notes receivable are unobservable and, as such, were categorized as Level 3. Fair value was determined using a discounted cash flow model that considered the contractual interest and principal payments discounted at a blended interest rate of the notes receivable.
For the Company’s level 3 financial instruments for which fair value is disclosed, an increase in the discount rate used to determine fair value would result in a decrease to the fair value. Conversely, a decrease in the discount rate would result in an increase to the fair value.
Disclosure about the fair value of financial instruments is based upon pertinent information available to management as of June 30, 2020 and December 31, 2019. Although management is not aware of any factors that would significantly affect the fair value amounts, such amounts were not comprehensively revalued for purposes of these financial statements since June 30, 2020. Current estimates of fair value may differ from the amounts presented herein.
9. DERIVATIVE FINANCIAL INSTRUMENTS
The following table summarizes the terms and fair values of the Company’s derivative financial instruments as of June 30, 2020 and December 31, 2019. The notional amounts provide an indication of the extent of the Company’s involvement in these instruments at that time, but do not represent exposure to credit, interest rate or market risks (amounts presented in thousands).

Hedge Product |  | Hedge Type |  | Designation |  | Notional Amount |  | Strike |  | Trade Date |  | Maturity Date |  | Fair value

|  |  |  |  |  | $ | 275,774 |  |  | $ | 275,774 |  |  |  |  |  |  |  |  |  |  |

(a) | Hedging unsecured variable rate debt.

The Company measures its derivative instruments at fair value and records them in “Other assets” and (“Other liabilities”) 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.
Disclosure about the fair value of derivative instruments is based upon pertinent information available to management as of June 30, 2020 and December 31, 2019. Although management is not aware of any factors that would significantly affect the fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since June 30, 2020. Current estimates of fair value may differ from the amounts presented herein.
10. LIMITED PARTNERS' NONCONTROLLING INTERESTS IN THE PARENT COMPANY

The aggregate book value of the noncontrolling interests associated with the redeemable common limited partnership interests in the accompanying consolidated balance sheet of the Parent Company was $9.1 million and $9.3 million as of June 30, 2020 and December 31, 2019, respectively. Under the applicable accounting guidance, the redemption value of limited partnership units are carried at fair value. The Parent Company believes that the aggregate settlement value of these interests (based on the number of units outstanding and the closing price of the common shares on the balance sheet date) was approximately $10.7 million and $15.5 million as of June 30, 2020 and December 31, 2019, respectively.

Redeemable common limited partnership units totaling 981,634 at June 30, 2020 and 981,626 at June 30, 2019, were excluded from the diluted earnings per share computations because they are not dilutive.
Unvested restricted shares are considered participating securities which require the use of the two-class method for the computation of basic and diluted earnings per share. For the three and six months ended June 30, 2020 and 2019, earnings representing nonforfeitable dividends as noted in the table above were allocated to the unvested restricted shares issued to the Company’s executives and other employees under the Company's shareholder-approved long-term incentive plan.

(a) | Included in Other liabilities on the consolidated balance sheets.

Net operating income (“NOI”) is a non-GAAP financial measure, which we define 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 and management fees. 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 presented by the Company may not be comparable to NOI reported by other companies that define NOI differently. 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 regarding 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 impairment 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 income, as defined by GAAP, to consolidated NOI, (in thousands):

14. 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, the Company has funded required leasing and capital reserve accounts for the benefit of the mortgage lenders with letters-of-credit. There were no letters-of-credit for a mortgage lender as of June 30, 2020. Certain of the tenant rents at properties that secure these mortgage loans are deposited into the loan servicer’s depository accounts, which are used to fund debt service, operating expenses, capital expenditures and the escrow and reserve accounts, as necessary. Any excess cash is included in cash and cash equivalents.
Environmental
As an owner of real estate, the Company is subject to various environmental laws of federal, state, and local governments. The Company’s compliance with existing laws has not had a material adverse effect on its financial condition and results of operations, and the Company does not believe it will have a material adverse effect in the future. However, the Company cannot predict the impact of unforeseen environmental contingencies or new or changed laws or regulations on its current Properties or on properties that the Company may acquire.
Debt Guarantees
As of June 30, 2020, the Company’s Real Estate Ventures had aggregate indebtedness of $618.9 million. These loans are generally mortgage or construction loans, most of which are nonrecourse to the Company, except for customary recourse carve-outs. As of June 30, 2020, the $150.0 million construction loan obtained by 4040 Wilson, located in Arlington, Virginia, for which the Company has a payment guarantee up to $41.3 million, is recourse to the Company. In addition, during construction undertaken by the 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.
Other Commitments or Contingencies
In connection with the Schuylkill Yards Project, the Company entered into a neighborhood engagement program and, as of June 30, 2020, had $8.3 million of future fixed contractual obligations. The Company also committed to fund additional contributions under
32

Table of Contents
the program. As of June 30, 2020, the Company estimates that these additional contributions, which are not fixed under the terms of agreement, will be $2.7 million.
As of June 30, 2020, the Company was under contract to acquire an office property containing approximately 170,000 rentable square feet located in Radnor, Pennsylvania for a purchase price of $20.3 million. The Company has paid $1.0 million towards the purchase price in the form of a non-refundable deposit and the transaction is expected to close during 2020.
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.
15. SUBSEQUENT EVENTS
On July 21, 2020, the Company sold a 30% preferred equity interest in One Commerce Square and Two Commerce Square in Philadelphia, PA for $115.0 million, which resulted in deconsolidation of the properties. The properties held by the newly formed joint venture remain encumbered by the existing $222.1 million mortgage. The transaction generated cash proceeds of $100.8 million, net of seller credits and closing costs. Additionally, we will record our investment at fair value and expect to recognize a gain on the transaction in excess of $270.0 million, subject to final closing settlements and accounting adjustments, during the three months ended September 30, 2020.

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 might cause actual results to differ materially from our expectations, many of which may be more likely to impact us as a result of the ongoing COVID-19 outbreak, are set forth in the “Risk Factors ” section of our Annual Report on Form 10-K for the year ended December 31, 2019 and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020. Accordingly, we caution readers not to place undue reliance on forward-looking statements. We assume no obligation to update or supplement forward-looking statements that become untrue because of subsequent events.
The discussion that follows is based primarily on our consolidated financial statements as of June 30, 2020 and December 31, 2019 and for the three and six months ended June 30, 2020 and 2019 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
During the six months ended June 30, 2020, we owned and managed properties within five markets: (1) Philadelphia Central Business District (“Philadelphia CBD”), (2) Pennsylvania Suburbs, (3) Austin, Texas, (4) Metropolitan Washington, D.C., 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 Austin, Texas segment includes properties in the City of Austin, Texas. The Metropolitan Washington, D.C. segment includes properties in Northern Virginia, Washington, D.C. and Southern Maryland. The Other segment includes properties in Camden County, New Jersey and New Castle County, 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 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.
We are closely monitoring the impact of the COVID-19 pandemic on all aspects of our business, including how it is impacting our tenants and business partners. Adverse changes in economic conditions, including the ongoing effects of the global COVID-19 pandemic, could result in a reduction of the availability of financing and potentially in higher borrowing costs. Vacancy rates may increase, and rental rates and rent collection rates may decline, during the remainder of 2020 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. The ongoing COVID-19 pandemic has significantly slowed global economic activity, caused significant volatility in financial markets, and resulted in unprecedented job losses. In addition, the government responses to control the pandemic are creating disruption in the global economy and supply chains and adversely impacting many industries, including owners and developers of office and mixed-use building. These adverse conditions have impacted our 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 June 30, 2020 was 90.7% compared to 93.0% at June 30, 2019.

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 2.4% of our aggregate final annualized base rents as of June 30, 2020 (representing approximately 2.8% of the net rentable square feet of the properties) are scheduled to expire without penalty in the remainder of 2020. We maintain an active dialogue with our tenants in an effort to maximize lease renewals. 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 $6.8 million or 3.4% of total receivables (including accrued rent receivable) as of June 30, 2020 compared to $8.0 million or 4.0% of total receivables (including accrued rent receivable) as
35

Table of Contents
of December 31, 2019. The decrease in the accounts receivable allowance as a percentage of the total receivables is primarily due to the write-off of the accrued rent receivable for certain retail tenants where revenue is now being recognized on a cash basis due to collectibility concerns arising from the economic conditions resulting from the COVID-19 outbreak.
If economic conditions deteriorate, including as a result of the recent COVID-19 outbreak, we may experience increases in past due accounts, defaults, lower occupancy and reduced effective rents. This condition would negatively affect our future net income and cash flows and could have a material adverse effect on our financial condition.
Development Risk
Development projects are subject to a variety of risks, including construction delays, construction cost overruns, building moratoriums, 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. During the second quarter of 2020, certain development projects were impacted by building moratoriums imposed by local governments as a result of COVID-19. These moratoriums have since been lifted in all geographies in which we have active development projects. The construction delays did not materially impact the development projects.
As of June 30, 2020 the following development and redevelopment projects remain under construction in progress and we were proceeding on the following activity (dollars, in thousands):

Property/Portfolio Name |  | Location |  | Expected Completion |  | Activity Type |  | Approximate Square Footage |  | Estimated Costs |  | Amount Funded
405 Colorado Street (a) |  | Austin, TX |  | Q1 2021 |  | Development |  | 204,000 |  |  | 116,000 |  |  | 47,400 |
426 W. Lancaster Avenue (b) |  | Devon, PA |  | Q3 2019 |  | Redevelopment |  | 56,000 |  |  | 14,900 |  |  | 13,400 |
3000 Market Street (c) |  | Philadelphia, PA |  | Q1 2021 |  | Redevelopment |  | 64,000 |  |  | 38,000 |  |  | 15,300 |

(a) | Estimated costs include $2.1 million of existing property basis through a ground lease. Project includes 520 parking spaces.

(b) | The property was vacated during the third quarter of 2017. Total project costs include $4.9 million of existing property basis. The renovation of the base building is completed and the building is 100% leased to a single tenant that is expected to commence their lease in Q3 2020 upon completion of the tenant improvements.

(c) | Estimated costs include $12.8 million of existing property basis.

In addition to the properties listed above, we have classified one parking facility in Philadelphia, Pennsylvania as redevelopment. As of June 30, 2020, there has been no material construction spend on this project.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
Management’s Discussion and Analysis of Financial Condition and Results of Operations discuss our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). The preparation of these financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Certain accounting policies are considered to be critical accounting policies, as they require management to make assumptions about matters that are highly uncertain at the time the estimate is made and changes in accounting estimate are reasonably likely to occur from period to period. Management bases its estimates and assumptions on historical experience and current economic conditions.
Our Annual Report on Form 10-K for the year ended December 31, 2019 contains a discussion of our critical accounting policies. There have been no significant changes in our critical accounting policies since December 31, 2019.
RESULTS OF OPERATIONS
The following discussion is based on our consolidated financial statements for the three and six months ended June 30, 2020 and 2019. 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, and management fees. General and administrative expenses
36

Table of Contents
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 13, ''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 13, ''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 Months Ended June 30, 2020 and June 30, 2019
The following comparison for the three months ended June 30, 2020 to the three months ended June 30, 2019, makes reference to the effect of the following:

(a) | “Same Store Property Portfolio,” which represents 87 properties containing an aggregate of approximately 14.1 million net rentable square feet, and represents properties that we owned for the three-month periods ended June 30, 2020 and 2019. The Same Store Property Portfolio includes properties acquired or placed in service on or prior to April 1, 2019 and owned through June 30, 2020 excluding properties classified as held for sale,

(b) | “Total Portfolio,” which represents all properties owned by us during the three months ended June 30, 2020 and 2019,

(c) | "Recently Completed/Acquired Properties," which represents one property placed into service or acquired on or subsequent to April 1, 2019,

(d) | "Development/Redevelopment Properties," which represents four properties currently in development/redevelopment. A property is excluded from our Same Store Property Portfolio and moved into Development/Redevelopment in the period that we determine to proceed with development/redevelopment for a future development strategy, and

(e) | "Q2 2019 through Q2 2020 Dispositions," which represents two properties disposed of from the three months ended June 30, 2019 through the three months ended June 30, 2020.

(b) | Pertains to Core Properties.

Total Revenue
Rents from the Total Portfolio decreased by $5.6 million during the second quarter of 2020 compared to the second quarter of 2019. The decrease in Rents is primarily driven by a decrease of $2.4 million related to the Q2 2019 through Q2 2020 Dispositions and a $1.6 million decrease across the Same Store Portfolio primarily due to the termination of a large tenant in the Metropolitan Washington D.C. segment as well as reduced parking income. There was also a decrease of $1.8 million in revenue from the residential and hotel components at the FMC Tower in our Philadelphia CBD segment related to the COVID-19 pandemic.
Third party management fees, labor reimbursement, and leasing income decreased by $1.0 million during the second quarter of 2020 compared to the second quarter of 2019 primarily due to a decrease in construction management fees for a third party building that was completed in the first quarter of 2020.

Property Operating Expenses
Property operating expenses across our Total Portfolio decreased $5.4 million for the three months ended June 30, 2020 compared to the three months ended June 30, 2019. The decrease in property operating expenses is primarily related to a decrease of $3.1 million due to decreased use of our properties by the tenants during the COVID-19 pandemic, a $1.0 million decrease at the hotel, residential, and restaurant components of FMC Tower due to the COVID-19 pandemic and associated store and building closures, and a $0.6 million decrease related to the Q2 2019 through Q2 2020 Dispositions.
Depreciation and Amortization
Depreciation and amortization expense decreased by $1.9 million for the second quarter of 2020 compared to the second quarter of 2019. The decrease in depreciation and amortization expense is primarily related to a $1.9 million decrease at the Same Store Property Portfolio, largely due to the write off of fully amortized tenant acquired in-place lease intangibles and a $0.8 million decrease related to the Q2 2019 through Q2 2020 Dispositions. These decreases were partially offset by an increase of $0.8 million related to our Development/Redevelopment Properties.
Net Gain on Real Estate Venture Transactions
The gain of $1.3 million recognized during the three months ended June 30, 2019 is related to proceeds from a connection agreement by the 51 N Street venture with the third-party owner of an adjacent property.
Net Income
Net income decreased by $2.3 million for the second quarter of 2020 compared to the second quarter of 2019 as a result of the factors described above.
Net Income per Common Share – fully diluted
Net income per share was $0.02 for the second quarter of 2020 as compared to net income per share of $0.03 for the second quarter of 2019 as a result of the factors described above.
Comparison of the Six Months Ended June 30, 2020 and June 30, 2019

Total Revenue
Rents from the Total Portfolio decreased by $4.5 million during the six months ended June 30, 2020 compared to the six months ended June 30, 2019, of which $4.1 million is related to the YTD 2019 and 2020 Dispositions as well as $2.2 million of decreases due to a reduction in hotel income and residential rents at the FMC Tower in our Philadelphia segment related to the COVID-19 pandemic. These decreases were partially offset by a $1.3 million increase at One Commerce Square and Two Commerce Square, which are held for sale as of June 30, 2020.
Other income decreased $1.6 million, which was primarily related to a decrease in income from the restaurant component of FMC Tower, as well as decreases in various fees from third parties due to the COVID-19 pandemic and associated store and building closures.

Property Operating Expenses
Property operating expenses across our Total Portfolio decreased $7.4 million for the six months ended June 30, 2020 compared to the six months ended June 30, 2019. The decrease in property operating expenses is primarily related to a decrease of $4.4 million due to decreased use of our properties by the tenants during the COVID-19 pandemic, a $1.3 million decrease at the hotel, residential, and restaurant components of FMC Tower due to the COVID-19 pandemic and associated store and building closures, and a decrease of $1.0 million related to the YTD 2019 and 2020 Dispositions.
Real Estate Taxes
Real estate taxes increased $1.7 million for the six months ended June 30, 2020 compared to the six months ended June 30, 2019. The increase in real estate taxes is primarily related to a $0.9 million increase in real estate tax assessments at the Same Store Property Portfolio, largely in the Austin segment, and $0.3 million related to Recently Completed/Acquired Properties.
Depreciation and Amortization
Depreciation and amortization expense decreased by $1.6 million for the six months ended June 30, 2020 compared to the six months ended June 30, 2019. The decrease in depreciation and amortization expense primarily relates to a $1.4 million decrease due to the YTD 2019 and 2020 Dispositions and a $0.8 million decrease related to the Same Store properties mainly related to an early termination at 1676 International Drive in 2019. These decreases were partially offset by an increase of $0.8 million related to the development properties.
General and Administrative
General and administrative expenses decreased by $1.3 million for the six months ended June 30, 2020 compared to the six months ended June 30, 2019, primarily due to a $1.6 million decrease in compensation related expenses, which is driven by changes to the vesting period of retirement eligible officers for the 2020 Restricted Performance Share Unit awards compared to the 2019 Restricted Performance Share Unit awards.
Net Gain on disposition of Real Estate
The gain of $2.6 million recognized during the six months ended June 30, 2020 is primarily related to the disposition of 52 East Swedesford Road, an office property in our Pennsylvania Suburbs Segment.
Net Gain on Sale of Undepreciated Real Estate
The gain of $1.3 million recognized during the six months ended June 30, 2019 resulted from the sale of 9 Presidential Boulevard and from consideration received during the six months ended June 30, 2019 related to the Libertyview disposition, which occurred in 2015.
The gain of 0.2 million recognized during the six months ended June 30, 2020 resulted from the sale of Keith Valley, a land parcel in our Pennsylvania Suburbs Segment.
Equity in Income (Loss) of Real Estate Ventures
Equity in loss of unconsolidated real estate ventures increased $1.3 million from the six months ended June 30, 2019 to the six months ended June 30, 2020 primarily due to the following:

• | $0.4 million increase related to depreciation and interest expense being recorded at our 4040 Wilson Venture due to portions of the project being placed into service as leases commenced;

• | $0.3 million increase related to our MAP Venture due to lower revenues from lower occupancy rate during the six months ended June 30, 2020 than the six months ended June 30, 2019; and

• | $0.2 million increase related to the disposition of our PJP Joint Venture in the fourth quarter of 2019.

Net Gain from Real Estate Venture Transactions
The $1.5 million net gain from Real Estate Venture transactions during the six months ended June 30, 2019 relates to the following:

• | $1.2 million of gain recognized related to proceeds from a connection agreement by the 51 N Street venture with the third-party owner of an adjacent property; and

41

Table of Contents

• | $0.3 million of additional proceeds during the first quarter of 2019 from the sale of the evo at Cira Centre South Venture, which was sold during the first quarter of 2018.

Net Income
Net income increased by $1.3 million from the six months ended June 30, 2020 compared to the six months ended June 30, 2019 as a result of the factors described above.
Net Income per Common Share – fully diluted
Net income per share was $0.07 for the six months ended June 30, 2020 as compared to net income per share of $0.06 for the six months ended June 30, 2019 as a result of the factors described above.
LIQUIDITY AND CAPITAL RESOURCES
General
Our principal liquidity funding needs for the next twelve months are as follows:

• | normal recurring expenses;

• | capital expenditures, including capital and tenant improvements and leasing costs;

• | debt service and principal repayment obligations;

• | current development and redevelopment costs;

• | commitments to unconsolidated real estate ventures;

• | distributions to shareholders to maintain our Parent Company’s REIT status;

• | possible acquisitions of properties, either directly or indirectly through the acquisition of equity interest therein; and

• | possible common share repurchases.

We expect to satisfy these needs using one or more of the following:

• | cash flows from operations;

• | distributions of cash from our unconsolidated real estate ventures;

• | cash and cash equivalent balances;

• | availability under our unsecured Credit Facility;

• | secured construction loans and long-term unsecured indebtedness;

• | issuances of Parent Company equity securities and/or units of the Operating Partnership; and

• | sales of real estate.

As of June 30, 2020, the Parent Company owned a 99.4% interest in the Operating Partnership. The remaining interest of approximately 0.6% 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.
As summarized above, we believe that our liquidity needs will be satisfied through available cash balances and cash flows from operations, financing activities and real estate sales. Rental revenue 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 during 2020 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 June 30, 2020 we were in compliance with all of our debt covenants and requirement obligations.
In addition, we are continuing to monitor the outbreak of the novel COVID-19 virus and the related economic impacts, market volatility, and business disruption, and its impact on our tenants. The severity and duration of the pandemic and its impact on our operations and liquidity is uncertain as this continues to evolve globally. However, if the outbreak continues, there will likely be continued negative economic impacts, market volatility, and business disruption which could negatively impact our tenants’ ability to pay rent, our ability to lease vacant space, and our ability to complete development and redevelopment projects, and these consequences, in turn, could materially impact our results of operations. We collected 99.6% of total cash-based rent due from tenants during the second quarter of 2020. In addition, approximately 98% of July total cash-based rent has been received from our tenants to date, which reflects a 99% collection rate from our office tenants.
We have granted rent relief requests primarily to our co-working and retail tenants. The relief requests have substantially all been in the form of rent deferral for varying lengths of time, but are primarily being repaid in 2020 and 2021. For those tenants we believe require rent relief, we have granted deferrals and, in some instances, rent abatements while receiving extended lease terms through favorable lease extensions. To date, we have provided $4.6 million of rent relief to 62 tenants approximating 1.1 million square feet. The deferrals represent approximately 1.0% of annualized revenue. We continue to assess the merits of rent deferral requests and can give no assurances on the outcomes of these ongoing negotiations, the amount and nature of the rent relief packages and ultimate recovery of the amounts deferred.
See Note 2, "Basis of Presentation - Accounting Standards Update," to our Consolidated Financial Statements for further information related to our accounting policies for rent concessions. Pursuant to our accounting elections, rental revenue continued to be recognized for tenants subject to deferral agreements, as long as such agreements did not result in a substantial increase in our rights as the lessor. As a result, rent deferrals did not have a material impact on revenues for the three months ended June 30, 2020.
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 under our unsecured credit facility when needed to fund distributions or pay expenses.
Our ability to incur additional debt is dependent upon a number of factors, including our credit ratings, the value of our unencumbered assets, our degree of leverage and borrowing restrictions imposed by our lenders. If one or more rating agencies were to downgrade our unsecured credit rating, our access to the unsecured debt market would be more limited and the interest rate under our unsecured credit facility and unsecured term loans would increase.
The Parent Company unconditionally guarantees the Operating Partnership’s secured and unsecured obligations, which, as of June 30, 2020, amounted to $311.5 million and $1,889.6 million, respectively.
Capital Markets
The Parent Company 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 covers 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 or in transactions exempt from registration.
See Note 11, ''Beneficiaries' Equity of the Parent Company” to our Consolidated Financial Statements for further information related to our share repurchase program during the three and six months ended June 30, 2020. We expect to fund any additional share repurchases with a combination of available cash balances and availability under our unsecured revolving credit facility. The timing and amounts of any repurchases will depend on a variety of factors, including market conditions, regulatory requirements, share prices, capital availability and other factors as determined by our management team. The repurchase program does not require the purchase of any minimum number of shares and may be suspended or discontinued at any time without notice.

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 six months ended June 30, 2020, we sold 14.0 acres of land as well as one office property for net cash proceeds of $3.5 and $17.5 million, respectively. On July 21, 2020 we sold a 30% preferred equity interest in One Commerce Square and Two Commerce Square for net cash proceeds of $100.8 million.
We expect that our primary uses of capital during the remainder of 2020 will be to fund our current development and redevelopment projects and also to repay $80.5 million in principal due upon maturity of the mortgage note for Two Logan Square, in Philadelphia, Pennsylvania, in August 2020, if not refinanced or extended. As of June 30, 2020, we had $44.8 million of cash and cash equivalents and $537.3 million of available borrowings under our Credit Facility, net of $1.7 million in letters of credit outstanding. Based on the foregoing, as well as cash flows from operations net of dividend requirements, we believe we have sufficient capital to fund our remaining capital requirements on existing development and redevelopment projects and pursue additional attractive investment 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 June 30, 2020 and December 31, 2019, we maintained cash and cash equivalents and restricted cash of $45.5 million and $91.2 million, respectively. We report and analyze our cash flows based on operating activities, investing activities, and financing activities. The following table summarizes changes in our cash flows (in thousands):

|  | Six Months Ended June 30,
Activity |  | 2020 |  | 2019 |  | (Decrease) Increase
Operating |  | $ | 100,320 |  |  | $ | 85,456 |  |  | $ | 14,864 |

Net cash flows |  | $ | (45,696 | ) |  | $ | 8,769 |  |  | $ | (54,465 | )

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.
Cash is used in investing activities to fund acquisitions, development, or redevelopment projects and recurring and nonrecurring capital expenditures. We selectively invest in new projects that enable us to take advantage of our development, leasing, financing, and property management skills and invest in existing buildings that meet our investment criteria. During the six months ended June 30, 2020, when compared to the six months ended June 30, 2019, the change in investing cash flows was due to the following activities (in thousands):

Acquisitions of real estate |  | $ | (11,432 | )
Capital expenditures and capitalized interest |  | 17,551 |
Capital improvements/acquisition deposits/leasing costs |  | (4,421 | )

Table of Contents
We generally fund our investment activity through the sale of real estate, property-level financing, credit facilities, senior unsecured notes, and construction loans. From time to time, we may issue common or preferred shares of beneficial interest, or the Operating Partnership may issue common or preferred units of limited partnership interest. During the six months ended June 30, 2020, when compared to the six months ended June 30, 2019, the change in financing cash flows was due to the following activities (in thousands):

The Operating Partnership is in compliance with all covenants as of June 30, 2020.
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
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. See Note 11, ''Beneficiaries' Equity of the Parent Company,” to our Consolidated Financial Statements for further information related to our dividends declared for the second quarter of 2020.
Contractual Obligations
Refer to our 2019 Annual Report on Form 10-K for a discussion of our contractual obligations. There have been no material changes, outside the ordinary course of business, to these contractual obligations during the three months ended June 30, 2020.
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 six months ended June 30, 2020 and 2019:

Item 3. Quantitative and Qualitative Disclosures about Market Risk
Market risk is the exposure to loss resulting from changes in interest rates, commodity prices and equity prices. In pursuing our business plan, the primary market risk to which we are exposed is interest rate risk. Changes in the general level of interest rates prevailing in the financial markets may affect the spread between our yield on invested assets and cost of funds and, in turn, our ability to make distributions or payments to our shareholders. While we have not experienced any significant credit losses, in the event of a significant rising interest rate environment and/or continued economic slowdown, defaults could increase and result in losses to us which would adversely affect our operating results and liquidity.
Interest Rate Risk and Sensitivity Analysis
The analysis below presents the sensitivity of the market value of the Operating Partnership’s financial instruments to selected changes in market rates. The range of changes chosen reflects its view of changes which are reasonably possible over a one-year period. Market values are the present value of projected future cash flows based on the market rates chosen.
Our financial instruments consist of both fixed and variable rate debt. As of June 30, 2020, our consolidated debt consisted of mortgage loans with an outstanding principal balance of $311.5 million, of which $222.1 million was classified as held for sale, and unsecured notes with an outstanding principal balance of $1,500.0 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, a $600.0 million Credit Facility with an outstanding balance of $61.0 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 two trust preferred securities with an outstanding principal balance of $52.8 million and our unsecured credit facility. 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
47

Table of Contents
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 instrument 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 instrument position.
If market rates of interest increase by 100 basis points, the fair value of our outstanding fixed-rate mortgage debt would decrease by approximately $6.4 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 $6.5 million.
As of June 30, 2020, based on prevailing interest rates and credit spreads, the fair value of our unsecured notes was $1,548.7 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 $15.5 million at June 30, 2020.
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 $389.6 million and $328.6 million at June 30, 2020 and December 31, 2019, respectively. The total fair value of our debt was approximately $369.4 million and $309.9 million at June 30, 2020 and December 31, 2019, 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 $14.0 million at June 30, 2020. If market rates of interest decrease by 100 basis points the fair value of our outstanding variable rate debt would increase by approximately $15.3 million.
These amounts were determined solely by considering the impact of hypothetical interest rates on our financial instruments. Due to the uncertainty of specific actions we may undertake to minimize possible effects of market interest rate increases, this analysis assumes no changes in our financial structure.
