EXPLANATORY NOTE
This report combines the annual reports on Form 10-K for the year ended December 31, 20102011 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, terms such as “we”, “us”, or “our” used in this report 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 December 31, 2010,2011, owned a 93.1%98.1% interest in the Operating Partnership. The remaining 6.9%1.9% interest consists of common units of limited partnership interest issued by the Operating Partnership to third parties in exchange for contributions of properties to the Operating Partnership. As the sole general partner of the Operating Partnership, the Parent Company has full and complete authority over the Operating Partnership’s day-to-day operations and management.
The Company believes that combining the annual reports on Form 10-K 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.
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. These members are officers of both the Parent Company and of the Operating Partnership.
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 the 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 public 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 direct or indirect incurrence of indebtedness or 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;

the following notes to the consolidated financial statements:Consolidated Financial Statements;
Noncontrolling Interests; and
Parent Company’s and Operating Partnership’s Equity
Liquidity and Capital Resources in the Management’s Discussion and Analysis of Financial Condition and Results of Operations.

This report also includes separate Item 9A. (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

2


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 debt, reference to the Company is appropriate because the business is one enterprise and the Parent Company operates the business through 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 operations on a consolidated basis and how management operates the Company.

Filing Format
This combined Form 10-K is being filed separately by Brandywine Realty Trust (the “Parent Company”) and Brandywine Operating Partnership, L.P. (the “Operating Partnership”).
Forward-Looking Statements
The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for forward-looking statements. This Annual Report on Form 10-K 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 include, but are not limited to:

the continuing impact of the recent credit crisis and global economic slowdown, which is having and may continue to have a negative effect on the following, among other things:
the fundamentals of our business, including overall market occupancy, demand for office space and rental rates;
the financial condition of our tenants, many of which are financial, legal and other professional firms, our lenders, counterparties to our derivative financial instruments and institutions that hold our cash balances and short-term investments, which may expose us to increased risks of default by these parties;
availability of financing on attractive terms or at all, which may adversely impact our future interest expense and our ability to pursue acquisition and development opportunities and refinance existing debt; and
a decline in real estate asset valuations, which may limit our ability to dispose of assets at attractive prices or obtain or maintain debt financing secured by our properties or on an unsecured basis.
changes in local real estate conditions (including changes in rental rates and the number of properties that compete with our properties);
changes in the economic conditions affecting industries in which our principal tenants compete;
the unavailability of equity and debt financing;
our failure to lease unoccupied space in accordance with our projections;
our failure to re-lease occupied space upon expiration of leases;
tenant defaults and the bankruptcy of major tenants;
increases in interest rates;
failure of interest rate hedging contracts to perform as expected and the effectiveness of such arrangements;
failure of acquisitions to perform as expected;
unanticipated costs associated with the acquisition, integration and operation of our acquisitions;
unanticipated costs to complete, lease-up and operate our developments and redevelopments;

6


unanticipated costs associated with land development, including building moratoriums and inability to obtain necessary zoning, land-use, building, occupancy and other required governmental approvals, construction cost increases or overruns and construction delays;
impairment charges;
increased costs for, or lack of availability of, adequate insurance, including for terrorist acts;
actual or threatened terrorist attacks;
demand for tenant services beyond those traditionally provided by landlords;
liability under environmental or other laws;
failure or bankruptcy of real estate venture partners;
inability of real estate venture partners to fund venture obligations;
failure of dispositions to close in a timely manner;
failure of buyers of our properties to comply with terms of their financing agreements to us;
earthquakes and other natural disasters;
the unforeseen impact of climate change and compliance costs relating to laws and regulations governing climate change;
risks associated with federal, state and local tax audits;
complex regulations relating to our status as a REIT and the adverse consequences of our failure to qualify as a REIT;

5


and
the impact of newly adopted accounting principles on our accounting policies and on period-to-period comparisons of financial results.
Given these uncertainties, and the other risks identified in the “Risk Factors” section and elsewhere in this Annual Report on Form 10-K, 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.

PART I

Item 1.
Business
Introduction
Introduction
We are a self-administered and self-managed REIT that provides leasing, property management, development, redevelopment, acquisition and other tenant-related services for a portfolio of office, mixed-use and industrial properties. As of December 31, 2010,2011, we owned and consolidated 233232 properties (collectively, the “Properties”) containing an aggregate of approximately 25.625.2 million net rentable square feet. The Properties include 208207 office properties, 20 industrial properties fourand five mixed-use properties and a garage property under redevelopment.properties. As of December 31, 2010,2011, we also owned interests in 1718 unconsolidated real estate ventures (collectively, the “Real Estate Ventures”) that own properties that contain approximately 6.56.7 million net rentable square feet. In addition, as of December 31, 2010,2011, we owned 444 acres of undeveloped land, and held options to purchase approximately 50952 additional acres of undeveloped land. The Properties and the properties owned by the Real Estate Ventures are located in or near Philadelphia, Pennsylvania; Metropolitan Washington, D.C.; Southern and Central New Jersey; Richmond, Virginia; Wilmington, Delaware; Austin, Texas and Oakland, Concord, Carlsbad and Rancho Bernardo, California. In addition to managing properties that we own, as of December 31, 2010,2011, we were managing approximately 7.87.4 million square feet of office and industrial properties for third parties and Real Estate Ventures. Unless otherwise indicated, all references to square feet represent net rentable area.
Organization
The Parent Company was organized and commenced its operations in 1986 as a Maryland REIT. The Parent Company owns its assets and conducts its operations through the Operating Partnership and subsidiaries of the Operating Partnership. The Operating Partnership was formed in 1996 as a Delaware limited partnership. The Parent Company controls the Operating Partnership as its sole general partner. As of December 31, 2010,2011, the Parent Company owned a 93.1%98.1% interest in the Operating Partnership. The remaining 6.9%1.9% interest in the Operating Partnership consists of common units of limited partnership interest issued to the holders in exchange for contributions of properties to the Operating Partnership. Our structure as an “UPREIT” is designed, in part, to permit persons contributing properties to us to defer some or all of the tax liability they might otherwise incur in a sale of properties.
The common units in the Operating Partnership consist of two classes: Class A units and Class F (2010) units. Holders of Class A units have the right to require redemption of their units at any time. At our option, we may satisfy the redemption of a Class A unit either for a common share of the Parent Company or for an amount of cash equal to the market price of one common share of the Parent Company (based on the average closing prices of the common shares on the New York Stock Exchange for the five-trading days ending on the redemption date). Class F (2010) units rank on a parity with Class A units as to distributions but do not begin to accrue distributions and are not entitled to allocations of income or loss prior to August 5, 2011. Thereafter, Class F (2010) units will be entitled to receive the same distributions that the Parent Company pays on its common shares, and the holder of the units will have the right to exchange the units for an equal number of common shares (or, at the Parent Company’s option, a cash payment equal to the number of units tendered for exchange multiplied by the average closing price of the common shares on the New York Stock Exchange for the five trading days ending on the date of the exchange).

Real Estate Acquisitions/Dispositions

On December 20, 2011, we formed a joint venture, Brandywine - AI Venture LLC (the "Venture"), with Current Creek Investments, LLC ("Current Creek"), a wholly-owned subsidiary of Allstate Insurance Company. We and Current Creek each own a 50% interest in the Venture. The Venture owns three office properties, which we contributed to the Venture upon its formation. The contributed office properties contain an aggregate of 587,317 net rentable square feet and consist of 3130 and 3141 Fairview Park Drive, both located in Falls Church, Virginia, and 7101 Wisconsin Avenue located in Bethesda, Maryland.

The mortgage loans have a weighted-average maturity of 7.4 years and bear interest at a weighted average rate of 4.4%. We transferred the properties to the Venture based on a $156.0 million valuation. Upon formation of the Venture, we received $120.1 million of aggregate proceeds from these transactions net of $2.9 million of transaction and venture formation costs. We used the net proceeds to reduce outstanding indebtedness under our building propertiesunsecured revolving credit facility and for general corporate purposes. We were engaged by the Venture to perform property management and leasing services at market rates.

We use borrowings under theour Credit Facility for general business purposes, including the acquisition, development and redevelopment of properties and the repayment of other debt. The
On December 15, 2011, we entered into binding agreements for lender commitments related to a new $600.0 million four-year unsecured revolving credit facility (the "New Credit Facility") and three unsecured term loans in the aggregate amount of $600.0 million (collectively, the “New Term Loans”), consisting of a $150.0 million three-year loan, a $250.0 million four-year loan and a $200.0 million seven-year loan. We closed on the New Credit Facility and New Term Loans on February 1, 2012 and used the initial advances under the New Term Loans to repay all balances outstanding under, and concurrently terminate, our then existing $600.0 million unsecured revolving credit facility (the "Prior Credit Facility") and $183.0 million unsecured term loan (the "Prior Term Loan"), each of which had been scheduled to mature on June 29, 2012. When we use the term "Credit Facility" in this Form 10-K, we are referring to the Prior Credit Facility (for events and time periods prior to February 1, 2012) and to the New Credit Facility (for events and time period on or after February 1, 2012).
We have the option to increase the amounts available to be advanced under the New Credit Facility, the $150.0 million three-year term loan, and the $250.0 million four-year term loan by an aggregate of $200.0 million, subject to customary conditions and limitations, by obtaining additional commitments from the current lenders and other financial institutions. We also have the option to extend the maturity datedates of each of the New Credit Facility, is June 29, 2011 (subject to an extension of the $150.0 million three-year term loan and the $250.0 million four-year term loan by one year at our option, upon our, subject to payment of an extension fee and other customary conditions and limitations.

prepay the $150.0 million three-year term and the $250.0 million four-year term loans at any time without penalty. The $200.0 million seven-year term loan is subject to a declining prepayment penalty ranging from 3.00% a year after closing, 2.00% after two years, 1.00% after three years and without penalty thereafter.
The spread to LIBOR for LIBOR-based loans under the New Credit Facility and New Term Loans will depend on our unsecured senior debt credit rating. Based on our current credit rating, the spread for such loans will be 150, 175, 175 and 190 basis points under the New Credit Facility, the $150.0 million three-year term loan, the $250.0 million four-year term loan and the $200.0 million seven-year term loan, respectively.

TheNew Term Loans, consistent with the Prior Credit Facility containsand Prior Term Loan, contain financial and non-financialoperating covenants and restrictions, including covenants that relate to our incurrence of additional debt; the granting of liens; consummation of mergers and consolidations; the disposition of assets and interests in subsidiaries; the making of loans and investments; and the payment of dividends. The restriction on dividends permits us to pay dividends to the greater of (i) an amount required for us to retain our qualification as a REIT and (ii) 95% of our funds from operations. The New Credit Facility includesand New Term Loans include financial covenants that require us to maintain an interest coverage ratio, a fixed charge coverage ratio, an unsecured debt ratio and an unencumbered cash flow ratio above specified levels; to maintain a minimum net worth above an amount determined on a specified formula; and to maintain a leverage ratio and a secured debt ratio below certain maximum levels. Another financial covenant limits the ratio of our unsecured debt to the value of our unencumbered properties.
We were in compliance with all financial and non-financial covenants under the Credit Facility and our credit agreements as of December 31, 2010.2011. We continuously monitor our compliance with all covenants. Certain covenants restrict our ability to obtain alternative sources of capital. While we believe that we will remain in compliance with our covenants, a continued slow-down in the economy and continued decrease in availability of debt financing could result in non-compliance with covenants.
Secured Debt Activity
On August 26, 2010, the Operating Partnership received $254.0April 5, 2011, we sold $325.0 million of grossour 4.95% Guaranteed Notes Due April 15, 2018 (the “2018 Notes”). The net proceeds from a $256.5 million forward financing commitment that the Operating Partnership obtained on June 29, 2009. The Operating Partnership paid a $17.7 million commitment fee in connection with this commitment. The loan proceeds, together with the commitment fee had been escrowed with an institutional trustee pending the completionsale of the IRS Philadelphia Campus2018 Notes, after the underwriters’ discount and the Cira South Garage as well as the commencement of the leases at these facilities. The financing consists of two separate loans: $209.7offering expenses, amounted to $318.9 million secured by the IRS Philadelphia Campus, and $46.8 million secured by the Cira South Garage. The lender held back $2.5 million of the loan proceeds pending completion of certain conditions related to the IRS Philadelphia Campus and the Cira South Garage. As of December 31, 2010, the Operating Partnership received $2.1 million of the amounts held back. The loans are non-recourse and are secured by the IRS Philadelphia Campus and the Cira South Garage, respectively. The loans bear interest at 5.93% with interest only through September 10, 2010 and thereafter require principal and interest monthly payments through its maturity in September 2030. The Operating Partnershipwere used the loan proceeds to reduce outstanding borrowings under itsour Credit Facility and for general corporate purposes.
Secured Debt Activity
During the year ended December 31, 2011, we prepaid an aggregate of $210.5 million of our secured debt without penalty using a combination of proceeds from asset sales, cash flow from operations and borrowings under the Credit Facility. The prepayments are summarized as follows (excluding accrued interest, in thousands):

Mortgage Note Payment Date Amount
Concord Airport Plaza Sep-11 $34,494
One Logan Square Jul-11 60,000
Midlantic, Lenox, DCCI Jun-11 56,514
Research Office Center Jun-11 39,145
Arboretum I, II, III, & V Apr-11 20,386
Total   $210,539
Additional Financing Activity
On August 5, 2010, the Operating Partnership issued 7,111,112 of Class F (2010) units in connection with the acquisition of Three Logan Square, an office property in Philadelphia, Pennsylvania. The Class F (2010) units do not accrue a dividend and are not entitled to income or loss allocations prior to August 5, 2011. They are also not exchangeable for Parent Company’s common shares for that period. For purposes of computing the total purchase price of Three Logan Square, the Class F (2010) units were valued based on the closing market price of the Parent Company’s common shares on the acquisition date of $11.54 less $0.60 to reflect that these units do not begin to accrue a dividend prior to August 5, 2011.
In June 2010, the Operating Partnership through one of its wholly owned taxable REIT subsidiaries (a“TRS”) received a $27.4 million contribution under the historic tax credit transaction that we entered into in 2008 with US Bancorp bringing the total contributions received to date to $61.4 million.
In March 2010, the Parent Company commenced auses its continuous equity offering program (the “Offering Program”), under which the Parent Companyit may sell up to an aggregate amount of 15,000,000 common shares until March 10, 2013. Through During the year ended December 31, 2010,2011, the Parent Company sold 5,742,268679,285 shares under the Offering Programthis program at an average sales price of $12.54$12.18 per share resulting in net proceeds of $70.8 million.$8.0 million. The Parent Company contributed the net proceeds from the sale of its shares under the Offering Program to the Operating Partnership in exchange for the issuance of 5,742,268679,285 common partnership units to the Parent Company. The Operating Partnership used the net proceeds from the sales contributed by the Parent Company to reduce borrowings under therepay balances on our Credit Facility and for general corporate purposes. From the inception of the Offering Program in March 2010 through December 31, 2011, the Parent Company has sold 6,421,553 common shares under this program, leaving in 8,578,447 shares available for sale.

Business Objective and Strategies for Growth
Our business objective is to deploy capital effectively to maximize our return on investment and thereby maximize our total return to shareholders. To accomplish this objective we seek to:

maximize cash flow through leasing strategies designed to capture rental growth as rental rates increase and as above and below-market leases are renewed;
attain a high tenant retention rate by providing a full array of property management and maintenance services and tenant service programs responsive to the varying needs of our diverse tenant base;
form joint venture opportunities with high-quality partners having attractive real estate holdings or significant financial resources;
utilize our reputation as a full-service real estate development and management organization to identify acquisition and development opportunities that will expand our business and create long-term value; and
increase the economic diversification of our tenant base while maximizing economies of scale.
We also consider the following to be important objectives:

to acquire and develop high-quality office and industrial properties at attractive yields in markets that we expect will experience economic growth and where we can achieve operating efficiencies;
to deploy our land inventory for development of high-quality office and industrial properties; and
to capitalize on our redevelopment expertise to selectively develop, redevelop and reposition properties in desirable locations.
We expect to concentrate our real estate activities in markets where we believe that:

current and projected market rents and absorption statistics justify construction activity;
we can maximize market penetration by accumulating a critical mass of properties and thereby enhance operating efficiencies;
barriers to entry (such as zoning restrictions, utility availability, infrastructure limitations, development moratoriums and limited developable land) will create supply constraints on office and industrial space; and
there is potential for economic growth, particularly job growth and industry diversification.
Operating Strategy
In this current economic environment, we expect to continue to operate in markets where we have a concentration advantage due to economies of scale. We believe that where possible, it is best to operate with a strong base of properties in order to benefit from the personnel allocation and the market strength associated with managing several properties in the same market. However, we intend to selectively dispose of properties and redeploy capital if we determine a property cannot meet our long term earnings growth expectations. We believe that recycling capital is an important aspect of maintaining the overall quality of our portfolio.
Our broader strategy remains focused on continuing to enhance liquidity and strengthen our balance sheet through capital retention, targeted sales activity and management of our existing and prospective liabilities.
In the long term, we believe that we are well positioned in our current markets and have the expertise to take advantage of both development and acquisition opportunities, as warranted by market and economic conditions, in new markets that have healthy long-term fundamentals and strong growth projections. This capability, combined with what we believe is a conservative financial structure, should allow us to achieve disciplined growth. These abilities are integral to our strategy of having a geographically and physically diverse portfolio of assets, which will meet the needs of our tenants.
We use experienced on site construction superintendents, operating under the supervision of project managers and senior management, to control the construction process and mitigate the various risks associated with real estate development.
In order to fund developments, redevelopments and acquisitions, as well as refurbish and improve existing Properties, we must use excess cash from operations after satisfying our dividend and other requirements. The availability of funds for new investments and maintenance of existing Properties depends in large measure on capital markets and liquidity factors over which we can exert little control. Past events, including failures and near failures of a number of large financial service companies, have made the capital markets increasingly volatile. As a result, many property owners are finding financing to be increasingly expensive and difficult to obtain. In addition, downgrades of our public debt ratings by Standard & Poor’s and Moody’s Investor Service could increase our cost of capital.

Policies With Respect To Certain Activities
The following is a discussion of our investment, financing and other policies. These policies have been determined by our Board of Trustees and our Board may revise these policies without a vote of shareholders.
Investments in Real Estate or Interests in Real Estate
We may develop, purchase or lease income-producing properties for long-term investment, expand and improve the properties presently owned or other properties purchased, or sell such properties, in whole or in part, as circumstances warrant. Although there is no limitation on the types of development activities that we may undertake, we expect that our development activities will meet current market demand and will generally be on a build-to-suit basis for particular tenants where a significant portion of the building is pre-leased before construction begins. We continue to participate with other entities in property ownership through existing joint ventures or other types of co-ownership. Our equity investments may be subject to existing or future mortgage financing and other indebtedness that will have priority over our equity investments.
Securities of or Interests in Entities Primarily Engaged in Real Estate Activities and Other Issuers
Subject to the percentage of ownership limitations and gross income tests necessary for REIT qualification, we may invest in securities of other REITs, other entities engaged in real estate activities or securities of other issuers. We may enter into joint ventures or partnerships for the purpose of obtaining an equity interest in a particular property. We do not currently intend to invest in the securities of other issuers except in connection with joint ventures or acquisitions of indirect interests in properties.
Investments in Real Estate Mortgages
While our current portfolio consists of, and our business objectives emphasize, equity investments in commercial real estate, we may, at the discretion of management or our Board of Trustees, invest in other types of equity real estate investments, mortgages and other real estate interests. We do not presently intend to invest to a significant extent in mortgages or deeds of trust, but may invest in participating mortgages if we conclude that we may benefit from the cash flow or any appreciation in the value of the property securing a mortgage. From time to time, we provide seller financing to buyers of our properties. We do this when the buyer requires additional funds for the purchase and provision of seller financing will be beneficial to us and the buyer compared to a mortgage loan from a third party lender.
Dispositions
Our disposition of properties is based upon management’s periodic review of our portfolio and the determination by management or our Board of Trustees that a disposition would be in our best interests. We intend to use selective dispositions to fund our capital and refinancing needs.
Financing Policies
A primary objective of our financing policy has been to manage our financial position to allow us to raise capital from a variety of sources at competitive rates. Our mortgages, credit facilities and unsecured debt securities contain restrictions on our ability to incur indebtedness. Our charter documents do not limit the indebtedness that we may incur. Our financing strategy is to maintain a strong and flexible financial position by limiting our debt to a prudent level and minimizing our variable interest rate exposure. We intend to finance future growth and future maturing debt with the most advantageous source of capital then available to us. These sources may include selling common or preferred equity and debt securities sold through public offerings or private placements, utilizing availability under the Credit Facility or incurring additional indebtedness through secured or unsecured borrowings. To qualify as a REIT, we must distribute to our shareholders each year at least ninety percent of our net taxable income, excluding any net capital gain. This distribution requirement limits our ability to fund future capital needs, including for acquisitions and developments, from income from operations. Therefore, we expect to continue to rely on third party sources of capital to fund future capital needs.

12


Working Capital Reserves
We maintain working capital reserves and access to borrowings in amounts that our management determines to be adequate to meet our normal contingencies.
Policies with Respect to Other Activities
We expect to issue additional common and preferred equity in the future and may authorize our Operating Partnership to issue additional common and preferred units of limited partnership interest, including to persons who contribute their interests in

11


properties to us in exchange for such units. We have not engaged in trading, underwriting or agency distribution or sale of securities of unaffiliated issuers and we do not intend to do so. We intend to make investments consistent with our qualification as a REIT, unless because of circumstances or changes in the Internal Revenue Code of 1986, as amended (or the Treasury Regulations), our Board of Trustees determines that it is no longer in our best interests to qualify as a REIT. We may make loans to third parties, including to joint ventures in which we participate and to buyers of our real estate. We intend to make investments in such a way that we will not be treated as an investment company under the Investment Company Act of 1940.
Management Activities
We provide third-party real estate management services primarily through wholly-owned subsidiaries (collectively, the “Management Companies”). As of December 31, 2010,2011, the Management Companies were managing properties containing an aggregate of approximately 33.432.6 million net rentable square feet, of which approximately 25.625.2 million net rentable square feet related to Properties owned by us and approximately 7.87.4 million net rentable square feet related to properties owned by third parties and unconsolidated Real Estate Ventures.
Geographic Segments
As of December 31, 2010,2011, we were managing our portfolio within seven segments: (1) Pennsylvania Suburbs, (2) Philadelphia Central Business District (“CBD”), (3) Metropolitan Washington D.C, (4) New Jersey/Delaware, (5) Richmond, Virginia, (6) Austin, Texas and (7) California. The Pennsylvania Suburbs segment includes properties in Chester, Delaware, and Montgomery counties in the Philadelphia suburbs. The Philadelphia CBD segment includes properties located in the City of Philadelphia in Pennsylvania. The Metropolitan Washington, D.C. segment includes properties in Northern Virginia and suburban Maryland. The New Jersey/Delaware segment includes properties in Burlington, Camden and Mercer counties and in New Castle county in the state of Delaware. The Richmond, Virginia segment includes properties primarily in Albemarle, Chesterfield, Goochland and Henrico counties and Durham, North Carolina. The Austin, Texas segment includes properties in Austin. The California segment includes properties in Oakland, Concord, Carlsbad and Rancho Bernardo. 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.
Competition
The real estate business is highly competitive. Our Properties compete for tenants with similar properties primarily on the basis of location, total occupancy costs (including base rent and operating expenses), services provided, and the design and condition of the improvements. We also face competition when attempting to acquire or develop real estate, including competition from domestic and foreign financial institutions, other REITs, life insurance companies, pension funds, partnerships and individual investors. Additionally, our ability to compete depends upon trends in the economies of our markets, investment alternatives, financial condition and operating results of current and prospective tenants, availability and cost of capital, construction and renovation costs, land availability, our ability to obtain necessary construction approvals, taxes, governmental regulations, legislation and population trends.
Insurance
We maintain commercial general liability and “all risk” property insurance on our properties. We intend to obtain similar coverage for properties we acquire in the future. There are types of losses, generally of a catastrophic nature, such as losses from war, terrorism, environmental issues, floods, hurricanes and earthquakes that are subject to limitations in certain areas or which may be uninsurable risks. We exercise our discretion in determining amounts, coverage limits and deductibility provisions of insurance, with a view to maintaining appropriate insurance on our investments at a reasonable cost and on suitable terms. If we suffer a substantial loss, our insurance coverage may not be sufficient to pay the full current market value or current replacement cost of our lost investment. Inflation, changes in building codes and ordinances, environmental considerations and other factors also might make it impractical to use insurance proceeds to fully replace or restore a property after it has been damaged or destroyed.

13


Employees
As of December 31, 2010,2011, we had 439402 full-time employees, including 3020 union employees.
Government Regulations Relating to the Environment
Many laws and governmental regulations relating to the environment apply to us and changes in these laws and regulations, or their interpretation by agencies and the courts, occur frequently and may adversely affect us.
Existing conditions at some of our Properties. Independent environmental consultants have conducted Phase I or similar

12


environmental site assessments on our Properties. We generally obtain these assessments prior to the acquisition of a Property and may later update them as required for subsequent financing of the property or as requested by a tenant. Site assessments are generally performed to ASTM standards then existing for Phase I site assessments, and typically include a historical review, a public records review, a visual inspection of the surveyed site, and the issuance of a written report. These assessments do not generally include any soil samplings or subsurface investigations. Depending on the age of the property, the Phase I may have included an assessment of asbestos-containing materials. For properties where asbestos-containing materials were identified or suspected, an operations and maintenance plan was generally prepared and implemented. See Note 2 to our consolidated financial statements for our evaluation in accordance with the accounting standard governing asset retirement obligations.
Historical operations at or near some of our properties, including the operation of underground storage tanks, may have caused soil or groundwater contamination. We are not aware of any such condition, liability or concern by any other means that would give rise to material, uninsured environmental liability. However, the assessments may have failed to reveal all environmental conditions, liabilities or compliance concerns; there may be material environmental conditions, liabilities or compliance concerns that a review failed to detect or which arose at a property after the review was completed; future laws, ordinances or regulations may impose material additional environmental liability; and current environmental conditions at our Properties may be affected in the future by tenants, third parties or the condition of land or operations near our Properties, such as the presence of underground storage tanks. We cannot be certain that costs of future environmental compliance will not affect our ability to make distributions to our shareholders.
Use of hazardous materials by some of our tenants.Some of our tenants handle hazardous substances and wastes on our properties as part of their routine operations. Environmental laws and regulations may subject these tenants, and potentially us, to liability resulting from such activities. We generally require our tenants, in their leases, to comply with these environmental laws and regulations and to indemnify us for any related liabilities. These tenants are primarily involved in the life sciences and the light industrial and warehouse businesses. We are not aware of any material noncompliance, liability or claim relating to hazardous or toxic substances or petroleum products in connection with any of our Properties, and we do not believe that on-going activities by our tenants will have a material adverse effect on our operations.
Costs related to government regulation and private litigation over environmental matters. Under environmental laws and regulations, we may be liable for the costs of removal, remediation or disposal of hazardous or toxic substances present or released on our Properties. These laws could impose liability without regard to whether we are responsible for, or knew of, the presence or release of the hazardous materials. Government investigations and remediation actions may entail substantial costs and the presence or release of hazardous substances on a property could result in governmental cleanup actions or personal injury or similar claims by private plaintiffs.

14


Potential environmental liabilities may exceed our environmental insurance coverage limits.We carry what we believe to be sufficient environmental insurance to cover potential liability for soil and groundwater contamination, mold impact, and the presence of asbestos-containing materials at the affected sites identified in our environmental site assessments. Our insurance policies are subject to conditions, qualifications and limitations. Therefore, we cannot provide any assurance that our insurance coverage will be sufficient to cover all liabilities for losses.
Potential environmental liabilities may adversely impact our ability to use or sell assets. The presence of contamination or the failure to remediate contamination may impair our ability to sell or lease real estate or to borrow using the real estate as collateral.
Other
We do not have any foreign operations and our business is not seasonal. Our operations are not dependent on a single tenant or a few tenants and no single tenant accounted for more than 10.0%10% of our total 20102011 revenue.
Code of Conduct
We maintain a Code of Business Conduct and Ethics applicable to our Board and all of our officers and employees, including our principal executive officer, principal financial officer, principal accounting officer, controller and persons performing similar functions.

Item 1A.
Risk Factors
Our results from operations and ability to make distributions on our equity and to pay debt service on our indebtedness may be affected by the risk factors set forth below. All investors should consider the following risk factors before deciding to purchase our securities.
Adverse economic and geopolitical conditions could have a material adverse effect on our results of operations, financial condition and our ability to pay distributions to you.
Our business is affected by the continued uncertaintyvolatility in the financial and credit markets, the sluggish recovery in the global economy, from the recent recession, and other market or economic challenges experienced by the U.S. economy or the real estate industry as a whole. While there are signs of recovery in the U.S. economy, the recovery rate has been much slower than anticipated. Our portfolio consists primarily of office buildings (as compared to a more diversified real estate portfolio); if economic conditions persist or again deteriorate, then our results of operations, financial condition, financial results and ability to service current debt and to pay distributions to our shareholders may be adversely affected by the following, among other potential conditions:

significant job losses in the financial and professional services industries may occur, which may decrease demand for our office space, causing market rental rates and property values to be negatively impacted;
our ability to borrow on terms and conditions that we find acceptable, or at all, may be limited, which could reduce our ability to complete development opportunities and refinance existing debt;
reduce our returns from both our existing operations and our development activities and increase our future interest expense;
reduced values of our properties may limit our ability to dispose of assets at attractive prices or to obtain debt financing secured by our properties and may reduce the availability of unsecured loans;
the value and liquidity of our short-term investments and cash deposits could be reduced as a result of a deterioration of the financial condition of the institutions that hold our cash deposits or the institutions or assets in which we have made short-term investments, the dislocation of the markets for our short-term investments, increased volatility in market rates for such investments or other factors;
reduced liquidity in debt markets and increased credit risk premiums for certain market participants may impair our ability to access capital; and
one or more lenders under our line of credit could refuse or be unable to fund their financing commitment to us and we may not be able to replace the financing commitment of any such lenders on favorable terms, or at all.
These conditions, which could have a material adverse effect on our results of operations, financial condition and ability to pay distributions, may continue or worsen in the future.
Our performance is subject to risks associated with our properties and with the real estate industry.
Our economic performance and the value of our real estate assets, and consequently the value of our securities, are subject to the risk that if our properties do not generate revenues sufficient to meet our operating expenses, including debt service and capital expenditures, our cash flow and ability to pay distributions to our shareholders will be adversely affected. Events or conditions beyond our control that may adversely affect our operations or the value of our properties include:

14



downturns in the national, regional and local economic climate including increases in the unemployment rate and inflation;
competition from other office, mixed use, industrial and commercial buildings;
local real estate market conditions, such as oversupply or reduction in demand for office, industrial or commercial space;
changes in interest rates and availability of financing;

16


vacancies, changes in market rental rates and the need to periodically repair, renovate and re-lease space;
increased operating costs, including insurance expense, utilities, real estate taxes, janitorial costs, state and local taxes, labor shortages and heightened security costs;
civil disturbances, earthquakes and other natural disasters, or terrorist acts or acts of war which may result in uninsured or underinsured losses;
significant expenditures associated with each investment, such as debt service payments, real estate taxes, insurance and maintenance costs which are generally not reduced when circumstances cause a reduction in revenues from a property; and
declines in the financial condition of our tenants and our ability to collect rents from our tenants.
The disruption in the debt capital markets could adversely affect us.
Notwithstanding the recent improvement in capital and credit markets, these markets are still considered volatile and disruptions in these markets are still possible. In some cases, the markets have produced downward pressure on stock prices and credit availability for certain issuers without regard to those issuers’ underlying financial strength. These events have an adverse effect on the availability of credit, the terms on which credit can be sourced and the overall cost of debt capital. This could negatively affect us by:

increasing our costs to finance our ongoing operations and fund our development and redevelopment activities;
reducing the availability of potential bidders for, and the amounts offered for, any properties we may wish to sell; and
preventing us from accessing necessary debt capital on a timely basis leading us to consider potentially more dilutive capital transactions such as undesirable sales of properties or equity securities.
We may suffer adverse consequences due to the financial difficulties, bankruptcy or insolvency of our tenants.
The current economic conditions have caused some of our tenants to experience financial difficulties. If more of our tenants were to continue to experience financial difficulties, including bankruptcy, insolvency or a general downturn in their business, there could be an adverse effect on our financial performance and distributions to shareholders. We cannot assure you that any tenant that files for bankruptcy protection will continue to pay us rent. A bankruptcy filing by or relating to one of our tenants or a lease guarantor would bar efforts by us to collect pre-bankruptcy debts from that tenant or lease guarantor, or its property, unless we receive an order permitting us to do so from the bankruptcy court. In addition, we cannot evict a tenant solely because of bankruptcy. The bankruptcy of a tenant or lease guarantor could delay our efforts to collect past due balances under the relevant leases, and could ultimately preclude collection of these sums. If a lease is assumed by the tenant in bankruptcy, all pre-bankruptcy balances due under the lease must be paid to us in full. If, however, a lease is rejected by a tenant in bankruptcy, we would have only a general, unsecured claim for damages. Any such unsecured claim would only be paid to the extent that funds are available and only in the same percentage as is paid to all other holders of general, unsecured claims. Restrictions under the bankruptcy laws further limit the amount of any other claims that we can make if a lease is rejected. As a result, it is likely that we would recover substantially less than the full value of the remaining rent during the term. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Factors that May Influence Future Results of Operations - Tenant Credit Risk."
The terms and covenants relating to our indebtedness could adversely impact our economic performance.
Like other real estate companies which incur debt, we are subject to risks associated with debt financing, such as the insufficiency of cash flow to meet required debt service payment obligations and the inability to refinance existing indebtedness. If our debt cannot be paid, refinanced or extended at maturity, we may not be able to make distributions to shareholders at expected levels or at all. Furthermore, an increase in our interest expense could adversely affect our cash flow and ability to make distributions to shareholders. If we do not meet our debt service obligations, any properties securing such indebtedness could be foreclosed on, which would have a material adverse effect on our cash flow and ability to make distributions and, depending on the number of properties foreclosed on, could threaten our continued viability.

17


Our Credit Facility, new term loanloans and the indenture governing our unsecured public debt securities contain (and any new or amended facility will contain) restrictions, requirements and other limitations on our ability to incur indebtedness, including total debt to asset ratios, secured debt to total asset ratios, debt service coverage ratios and minimum ratios of unencumbered assets to unsecured debt which we must maintain. Our ability to borrow under our credit facilities is subject to compliance with such financial and other covenants. In the event that we fail to satisfy these covenants, we would be in default under the credit facilities,

15


the term loan and the indenture and may be required to repay such debt with capital from other sources. Under such circumstances, other sources of capital may not be available to us, or may be available only on unattractive terms. In addition, the mortgages on our properties contain customary covenants such as those that limit our ability, without the prior consent of the lender, to further mortgage the applicable property or to discontinue insurance coverage. If we breach covenants in our secured debt agreements, the lenders can declare a default and take possession of the property securing the defaulted loan.
Increases in interest rates on variable rate indebtedness will increase our interest expense, which could adversely affect our cash flow and ability to make distributions to shareholders. Rising interest rates could also restrict our ability to refinance existing debt when it matures. In addition, an increase in interest rates could decrease the amounts that third parties are willing to pay for our assets, thereby limiting our ability to alter our portfolio promptly in relation to economic or other conditions. We entered into and may, from time to time, enter into agreements such as interest rate hedges, swaps, floors, caps and other interest rate hedging contracts with respect to a portion of our variable rate debt. Although these agreements may lessen the impact of rising interest rates on us, they also expose us to the risk that other parties to the agreements will not perform or that we cannot enforce the agreements.
Our degree of leverage could limit our ability to obtain additional financing or affect the market price of our equity shares or debt securities.
Our degree of leverage could affect our ability to obtain additional financing for working capital expenditures, development, acquisitions or other general corporate purposespurposes. In the event that our unsecured debt is downgraded by Moody’s Investor Services or Standard & Poor’s from the current ratings, we would likely incur higher borrowing costs and the market prices of our common shares and debt securities might decline. Our degree of leverage could also make us more vulnerable to a downturn in business or the economy in general.
We may experience increased operating costs, which might reduce our profitability.
Our properties are subject to increases in operating expenses such as for cleaning, electricity, heating, ventilation and air conditioning, administrative costs and other costs associated with security, landscaping and repairs and maintenance of our properties. In general, under our leases with tenants, we pass through all or a portion of these costs to them. We cannot assure you, however, that tenants will actually bear the full burden of these higher costs, or that such increased costs will not lead them, or other prospective tenants, to seek office space elsewhere. If operating expenses increase, the availability of other comparable office space in our core geographic markets might limit our ability to increase rents; if operating expenses increase without a corresponding increase in revenues, our profitability could diminish and limit our ability to make distributions to shareholders.
Our investment in property development or redevelopment may be more costly or difficult to complete than we anticipate.
We intend to continue to develop properties where market conditions warrant such investment. Once made, these investments may not produce results in accordance with our expectations. Risks associated with our development and construction activities include:

the unavailability of favorable financing alternatives in the private and public debt markets;
having sufficient capital to pay development costs;
unprecedented market volatility in the share price of REITs;
dependence on the financial services sector as part of our tenant base;
construction costs exceeding original estimates due to rising interest rates, diminished availability of materials and labor, and increases in the costs of materials and labor;
construction and lease-up delays resulting in increased debt service, fixed expenses and construction or renovation costs;
expenditure of funds and devotion of management’s time to projects that we do not complete;
the unavailability or scarcity of utilities;

18


occupancy rates and rents at newly completed properties may fluctuate depending on a number of factors, including market and economic conditions, resulting in lower than projected rental rates and a corresponding lower return on our investment;
complications (including building moratoriums and anti-growth legislation) in obtaining necessary zoning, occupancy and other governmental permits; and
increased use restrictions by local zoning or planning authorities limiting our ability to develop and impacting the size of developments.
See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Factors that May Influence Future Results of Operations - Development Risk."
We face risks associated with property acquisitions.

16


We have recently acquired properties, and may in the future continue to acquire, properties and portfolios of properties, including large portfolios that would increase our size and potentially alter our capital structure. Although we believe that the acquisitions that we have completed and that we expect to undertake in the future have, and will, enhance our future financial performance, the success of such transactions is subject to a number of factors, including the risks that:

we may not be able to obtain financing for acquisitions on favorable terms;
acquired properties may fail to perform as expected;
the actual costs of repositioning or redeveloping acquired properties may be higher than our estimates;
acquired properties may be located in new markets where we may have limited knowledge and understanding of the local economy, an absence of business relationships in the area or unfamiliarity with local governmental and permitting procedures; and
we may not be able to efficiently integrate acquired properties, particularly portfolios of properties, into our organization and manage new properties in a way that allows us to realize cost savings and synergies.
We acquired in the past and in the future may acquire properties or portfolios of properties through tax deferred contribution transactions in exchange for partnership interests in our Operating Partnership. This acquisition structure has the effect, among other factors, of reducing the amount of tax depreciation we can deduct over the tax life of the acquired properties, and typically requires that we agree to protect the contributors’ ability to defer recognition of taxable gain through restrictions on our ability to dispose of the acquired properties and/or the allocation of partnership debt to the contributors to maintain their tax bases. These restrictions on dispositions could limit our ability to sell an asset or pay down partnership debt during a specified time, or on terms, that would be favorable absent such restrictions.
Acquired properties may subject us to known and unknown liabilities.
Properties that we acquire may be subject to known and unknown liabilities for which we would have no recourse, or only limited recourse, to the former owners of such properties. As a result, if a liability were asserted against us based upon ownership of an acquired property, we might be required to pay significant sums to settle it, which could adversely affect our financial results and cash flow. Unknown liabilities relating to acquired properties could include:

liabilities for clean-up of pre-existing disclosed or undisclosed environmental contamination;
claims by tenants, vendors or other persons arising on account of actions or omissions of the former owners of the properties; and
liabilities incurred in the ordinary course of business.

19


We have agreed not to sell certain of our properties and to maintain indebtedness subject to guarantees.
We agreed not to sell some of our properties for varying periods of time, in transactions that would trigger taxable income to the former owners, and we may enter into similar arrangements as a part of future property acquisitions. These agreements generally provide that we may dispose of the subject properties only in transactions that qualify as tax-free exchanges under Section 1031 of the Internal Revenue Code or in other tax deferred transactions. Such transactions can be difficult to complete and can result in the property acquired in exchange for the disposed of property inheriting the tax attributes (including tax protection covenants) of the sold property. Violation of these tax protection agreements would impose significant costs on us. As a result, we are restricted with respect to decisions related to financing, encumbering, expanding or selling these properties.
We have also entered into agreements that provide prior owners of properties with the right to guarantee specific amounts of indebtedness and, in the event that the specific indebtedness that they guarantee is repaid or reduced, we would be required to provide substitute indebtedness for them to guarantee. These agreements may hinder actions that we may otherwise desire to take to repay or refinance guaranteed indebtedness because we would be required to make payments to the beneficiaries of such agreements if we violate these agreements.
We may be unable to renew leases or re-lease space as leases expire; certain leases may expire early.
If tenants do not renew their leases upon expiration, we may be unable to re-lease the space. Even if the tenants do renew their leases or if we can re-lease the space, the terms of renewal or re-leasing (including the cost of required renovations) may be less favorable than the current lease terms. Certain leases grant the tenants an early termination right upon payment of a termination penalty or if we fail to comply with certain material lease terms. Our inability to renew or release spaces and the early termination of certain leases could affect our ability to make distributions to shareholders. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Factors that May Influence Future Results of Operations - Tenant Rollover Risk."

17


We face significant competition from other real estate developers.
We compete with real estate developers, operators and institutions for tenants and acquisition and development opportunities. Some of these competitors may have significantly greater financial resources than we have. Such competition may reduce the number of suitable investment opportunities available to us, may interfere with our ability to attract and retain tenants and may increase vacancies, which could result in increased supply and lower market rental rates, reducing our bargaining leverage and adversely affect our ability to improve our operating leverage. In addition, some of our competitors may be willing (e.g., because their properties may have vacancy rates higher than those for our properties) to make space available at lower rental rates or with higher tenant concession percentages than available space in our properties. We cannot assure you that this competition will not adversely affect our cash flow and our ability to make distributions to shareholders.
Property ownership through joint ventures may limit our ability to act exclusively in our interest.
We develop, acquire, and acquirecontribute properties in joint ventures with other persons or entities when we believe circumstances warrant the use of such structures. As of December 31, 2010,2011, we had investments in 1718 unconsolidated real estate ventures. Our net investments in the 1718 unconsolidated real estate ventures aggregated approximately $84.4$115.8 million as of December 31, 2010.2011. We could become engaged in a dispute with one or more of our joint venture partners that might affect our ability to operate a jointly-owned property. Moreover, our joint venture partners may, at any time, have business, economic or other objectives that are inconsistent with our objectives, including objectives that relate to the appropriate timing and terms of any sale or refinancing of a property. In some instances, our joint venture partners may have competing interests in our markets that could create conflicts of interest. If the objectives of our joint venture partners or the lenders to our joint ventures are inconsistent with our own objectives, we may not be able to act exclusively in our interests. Furthermore, if the current constrained credit conditions in the capital markets persist or deteriorate further, the value of our investments could deteriorate and we could be required to reduce the carrying value of our equity method investments if a loss in the carrying value of the investment is other than a temporary decline pursuant to the accounting standard governing the equity method of accounting for investments in common stock.accounting.

20


Because real estate is illiquid, we may not be able to sell properties when appropriate.
Real estate investments generally, and in particular large office and industrial/flex properties like those that we own, often cannot be sold quickly. The capitalization rates at which properties may be sold are generally higher than historic rates, thereby reducing our potential proceeds from sale. Consequently, we may not be able to alter our portfolio promptly in response to changes in economic or other conditions. In addition, the Internal Revenue Code limits our ability to sell properties that we have held for fewer than fourtwo years without potential adverse consequences to our shareholders. Furthermore, properties that we have developed and have owned for a significant period of time or that we acquired in exchange for partnership interests in our operating partnership often have a low tax basis. If we were to dispose of any of these properties in a taxable transaction, we may be required under provisions of the Internal Revenue Code applicable to REITs to distribute a significant amount of the taxable gain to our shareholders and this could, in turn, impact our cash flow. In some cases, tax protection agreements with third parties will prevent us from selling certain properties in a taxable transaction without incurring substantial costs. In addition, purchase options and rights of first refusal held by tenants or partners in joint ventures may also limit our ability to sell certain properties. All of these factors reduce our ability to respond to changes in the performance of our investments and could adversely affect our cash flow and ability to make distributions to shareholders as well as the ability of someone to purchase us, even if a purchase were in our shareholders’ best interests.
Some potential losses are not covered by insurance.
We currently carry comprehensive “all-risk” property, and rental loss insurance and commercial general liability coverage on all of our properties. We believe the policy specifications and insured limits of these policies are adequate and appropriate. There are, however, types of losses, such as lease and other contract claims, biological, radiological and nuclear hazards and acts of war that generally are not insured. We cannot assure you that we will be able to renew insurance coverage in an adequate amount or at reasonable prices. In addition, insurance companies may no longer offer coverage against certain types of losses, such as losses due to earthquake, terrorist acts and mold, flood, or, if offered, these types of insurance may be prohibitively expensive. Should an uninsured loss or a loss in excess of insured limits occur, we could lose all or a portion of the capital we have invested in a property, as well as the anticipated future revenue from the property. In such an event, we might nevertheless remain obligated for any mortgage debt or other financial obligations related to the property. We cannot assure you that material losses in excess of insurance proceeds will not occur in the future. If any of our properties were to experience a catastrophic loss, it could seriously disrupt our operations, delay revenue and result in large expenses to repair or rebuild the property. Such events could adversely affect our cash flow and ability to make distributions to shareholders. If one or more of our insurance providers were to fail to pay a claim as a result of insolvency, bankruptcy or otherwise, the nonpayment of such claims could have an adverse effect on our financial condition and results of operations. In addition, if one or more of our insurance providers were to become subject to insolvency, bankruptcy or other proceedings and our insurance policies with the provider were terminated or cancelled as a result

18


of those proceedings, we cannot guarantee that we would be able to find alternative coverage in adequate amounts or at reasonable prices. In such case, we could experience a lapse in any or adequate insurance coverage with respect to one or more properties and be exposed to potential losses relating to any claims that may arise during such period of lapsed or inadequate coverage.
Terrorist attacks and other acts of violence or war may adversely impact our performance and may affect the markets on which our securities are traded.
Terrorist attacks against our properties, or against the United States or our interests, may negatively impact our operations and the value of our securities. Attacks or armed conflicts could result in increased operating costs; for example, it might cost more in the future for building security, property and casualty insurance, and property maintenance. As a result of terrorist activities and other market conditions, the cost of insurance coverage for our properties could also increase. We might not be able to pass through the increased costs associated with such increased security measures and insurance to our tenants, which could reduce our profitability and cash flow. Furthermore, any terrorist attacks or armed conflicts could result in increased volatility in or damage to the United States and worldwide financial markets and economy. Such adverse economic conditions could affect the ability of our tenants to pay rent and our cost of capital, which could have a negative impact on our results.
Our ability to make distributions is subject to various risks.
Historically, we have paid quarterly distributions to our shareholders. Our ability to make distributions in the future will depend upon:

the operational and financial performance of our properties;
capital expenditures with respect to existing, developed and newly acquired properties;
general and administrative costs associated with our operation as a publicly-held REIT;
the amount of, and the interest rates on, our debt; and
the absence of significant expenditures relating to environmental and other regulatory matters.

21


Certain of these matters are beyond our control and any significant difference between our expectations and actual results could have a material adverse effect on our cash flow and our ability to make distributions to shareholders.
Changes in the law may adversely affect our cash flow.
Because increases in income and service taxes are generally not passed through to tenants under leases, such increases may adversely affect our cash flow and ability to make expected distributions to shareholders. Our properties are also subject to various regulatory requirements, such as those relating to the environment, fire and safety. Our failure to comply with these requirements could result in the imposition of fines and damage awards and could result in a default under some of our tenant leases. Moreover, the costs to comply with any new or different regulations could adversely affect our cash flow and our ability to make distributions. Although we believe that our properties are in material compliance with all such requirements, we cannot assure you that these requirements will not change or that newly imposed requirements will not require significant expenditures in order to be compliant.
Potential liability for environmental contamination could result in substantial costs.
Under various federal, state and local laws, ordinances and regulations, we may be liable for the costs to investigate and remove or remediate hazardous or toxic substances on or in our properties, often regardless of whether we know of or are responsible for the presence of these substances. These costs may be substantial. While we do maintain environmental insurance, we can not be assured that our insurance coverage will be sufficient to protect us from all of the aforesaid remediation costs. Also, if hazardous or toxic substances are present on a property, or if we fail to properly remediate such substances, our ability to sell or rent the property or to borrow using that property as collateral may be adversely affected.
Other laws and regulations govern indoor and outdoor air quality including those that can require the abatement or removal of asbestos-containing materials in the event of damage, demolition, renovation or remodeling and also govern emissions of and exposure to asbestos fibers in the air. The maintenance and removal of lead paint and certain electrical equipment containing polychlorinated biphenyls (PCBs) and underground storage tanks are also regulated by federal and state laws. We are also subject to risks associated with human exposure to chemical or biological contaminants such as molds, pollens, viruses and bacteria which, above certain levels, can be alleged to be connected to allergic or other health effects and symptoms in susceptible individuals. We could incur fines for environmental compliance and be held liable for the costs of remedial action with respect to the foregoing regulated substances or tanks or related claims arising out of environmental contamination or human exposure to contamination at or from our properties.
Additionally, we develop, manage, lease and/or operate various properties for third parties. Consequently, we may be considered

19


to have been or to be an operator of these properties and, therefore, potentially liable for removal or remediation costs or other potential costs that could relate to hazardous or toxic substances.
An earthquake or other natural disasters could adversely affect our business.
Some of our properties are located in California which is a high risk geographical area for earthquakes or other natural disasters. Depending upon its magnitude, an earthquake could severely damage our properties which would adversely affect our business. We maintain earthquake insurance for our California properties and the resulting business interruption. We cannot assure you that our insurance will be sufficient if there is a major earthquake.
Americans with Disabilities Act compliance could be costly.
The Americans with Disabilities Act of 1990, as amended (“ADA”) requires that all public accommodations and commercial facilities, including office buildings, meet certain federal requirements related to access and use by disabled persons. Compliance with ADA requirements could involve the removal of structural barriers from certain disabled persons’ entrances which could adversely affect our financial condition and results of operations. Other federal, state and local laws may require modifications to or restrict further renovations of our properties with respect to such accesses. Although we believe that our properties are in material compliance with present requirements, noncompliance with the ADA or similar or related laws or regulations could result in the United States government imposing fines or private litigants being awarded damages against us. In addition, changes to existing requirements or enactments of new requirements could require significant expenditures. Such costs may adversely affect our cash flow and ability to make distributions to shareholders.

22


Our status as a REIT (or any of our REIT subsidiaries) is dependent on compliance with federal income tax requirements.
If we (or any of our REIT subsidiaries)subsidiaries that elects to be taxable as a REIT) fail to qualify as a REIT, we or the affected REIT subsidiaries would be subject to federal income tax at regular corporate rates. Also, unless the IRS granted us or our affected REIT subsidiaries, as the case may be, relief under certain statutory provisions, we or it would remain disqualified as a REIT for four years following the year it first failed to qualify. If we or any of our REIT subsidiaries fails to qualify as a REIT, we or they would be required to pay significant income taxes and would, therefore, have less money available for investments or for distributions to shareholders. This would likely have a material adverse effect on the value of the combined company’s securities. In addition, we or our affected REIT subsidiaries would no longer be required to make any distributions to shareholders.
Failure of the Operating Partnership (or a subsidiary partnership) to be treated as a partnership would have serious adverse consequences to our shareholders. If the IRS were to successfully challenge the tax status of the Operating Partnership or any of its subsidiary partnerships for federal income tax purposes, the Operating Partnership or the affected subsidiary partnership would be taxable as a corporation. In such event we would cease to qualify as a REIT and the imposition of a corporate tax on the Operating Partnership or a subsidiary partnership would reduce the amount of cash available for distribution from the Operating Partnership to us and ultimately to our shareholders.
Even if we qualify as a REIT, we will be required to pay certain federal, state and local taxes on our income and properties. In addition, our taxable REIT subsidiaries will be subject to federal, state and local income tax at regular corporate rates on their net taxable income derived from management, leasing and related service business. If we have net income from a prohibited transaction, such income will be subject to a 100% tax.
Failure to qualify as a REIT would subject us to U.S. federal income tax which would reduce the cash available for distribution to our shareholders.
We operate our business to qualify to be taxed as a REIT for federal income tax purposes. We have not requested and do not plan to request a ruling from the IRS that we qualify as a REIT, and the statements in this Annual Report on Form 10-K are not binding on the IRS or any court. As a REIT, we generally will not be subject to federal income tax on the income that we distribute currently to our shareholders. Many of the REIT requirements, however, are highly technical and complex. The determination that we are a REIT requires an analysis of various factual matters and circumstances that may not be totally within our control. For example, to qualify as a REIT, at least 95% of our gross income must come from specific passive sources, such as rent, that are itemized in the REIT tax laws. In addition, to qualify as a REIT, we cannot own specified amounts of debt and equity securities of some issuers. We also are required to distribute to our shareholders with respect to each year at least 90% of our REIT taxable income (excluding net capital gains). The fact that we hold substantially all of our assets through the Operating Partnership and its subsidiaries further complicates the application of the REIT requirements for us. Even a technical or inadvertent mistake could jeopardize our REIT status and, given the highly complex nature of the rules governing REITs and the ongoing importance of factual determinations, we cannot provide any assurance that we will continue to qualify as a REIT. Furthermore, Congress and the IRS might make changes to the tax laws and regulations, and the courts might issue new rulings, that make it more difficult,

20


or impossible, for us to remain qualified as a REIT. If we fail to qualify as a REIT for federal income tax purposes and are able to avail ourselves of one or more of the statutory savings provisions in order to maintain our REIT status, we would nevertheless be required to pay penalty taxes of $50,000 or more for each such failure.
If we fail to qualify as a REIT for federal income tax purposes, and are unable to avail ourselves of certain savings provisions set forth in the Internal Revenue Code, we would be subject to federal income tax at regular corporate rates on all of our income. As a taxable corporation, we would not be allowed to take a deduction for distributions to shareholders in computing our taxable income or pass through long term capital gains to individual shareholders at favorable rates. We also could be subject to the federal alternative minimum tax and possibly increased state and local taxes. We would not be able to elect to be taxed as a REIT for four years following the year we first failed to qualify unless the IRS were to grant us relief under certain statutory provisions. If we failed to qualify as a REIT, we would have to pay significant income taxes, which would reduce our net earnings available for investment or distribution to our shareholders. This likely would have a significant adverse effect on our earnings and likely would adversely affect the value of our securities. In addition, we would no longer be required to pay any distributions to shareholders.
Failure of the Operating Partnership (or a subsidiary partnership) to be treated as a partnership would have serious adverse consequences to our shareholders. If the IRS were to successfully challenge the tax status of the Operating Partnership or any of its subsidiary partnerships for federal income tax purposes, the Operating Partnership or the affected subsidiary partnership would be taxable as a corporation. In such event we would cease to qualify as a REIT and the imposition of a corporate tax on the Operating Partnership or a subsidiary partnership would reduce the amount of cash available for distribution from the Operating Partnership to us and ultimately to our shareholders.

23


To maintain our REIT status, we may be forced to borrow funds on a short term basis during unfavorable market conditions.
As a REIT, we are subject to certain distribution requirements, including the requirement to distribute 90% of our REIT taxable income, that may result in our having to make distributions at disadvantageous time or to borrow funds at unfavorable rates. Compliance with this requirement may hinder our ability to operate solely on the basis of maximizing profits.
We will pay some taxes even if we qualify as a REIT, which will reduce the cash available for distribution to our shareholders.
Even if we qualify as a REIT for federal income tax purposes, we will be required to pay certain federal, state and local taxes on our income and property. For example, we will be subject to income tax to the extent we distribute less than 100% of our REIT taxable income, including capital gains. Additionally, we will be subject to a 4% nondeductible excise tax on the amount, if any, by which dividends paid by us in any calendar year are less than the sum of 85% of our ordinary income, 95% of our capital gain net income and 100% of our undistributed income from prior years. Moreover, if we have net income from “prohibited transactions,” that income will be subject to a 100% penalty tax. In general, prohibited transactions are sales or other dispositions of property held primarily for sale to customers in the ordinary course of business. The determination as to whether a particular sale is a prohibited transaction depends on the facts and circumstances related to that sale. We cannot guarantee that sales of our properties would not be prohibited transactions unless we comply with certain statutory safe-harbor provisions.
In addition, any net taxable income earned directly by our taxable REIT subsidiaries, or through entities that are disregarded for federal income tax purposes as entities separate from our taxable REIT subsidiaries, will be subject to federal and possibly state corporate income tax. In this regard, several provisions of the laws applicable to REITs and their subsidiaries ensure that a taxable REIT subsidiary will be subject to an appropriate level of federal income taxation. For example, a taxable REIT subsidiary is limited in its ability to deduct certain interest payments made to an affiliated REIT. In addition, the REIT has to pay a 100% penalty tax on some payments that it receives or on some deductions taken by a taxable REIT subsidiary if the economic arrangements between the REIT, the REIT’s customers, and the taxable REIT subsidiary are not comparable to similar arrangements between unrelated parties. Finally, some state and local jurisdictions may tax some of our income even though as a REIT we are not subject to federal income tax on that income because not all states and localities follow the federal income tax treatment of REITs. To the extent that we and our affiliates are required to pay federal, state and local taxes, we will have less cash available for distributions to our shareholders.
We face possible federal, state and local tax audits.
Because we are organized and qualify as a REIT, we are generally not subject to federal income taxes, but are subject to certain state and local taxes. Certain entities through which we own real estate either have undergone, or are currently undergoing, tax audits. Although we believe that we have substantial arguments in favor of our positions in the ongoing audits, in some instances there is no controlling precedent or interpretive guidance on the specific point at issue. There can be no assurance that these or future audits will not have a material adverse effect on our results of operations. The Operating Partnership has been audited by the Internal Revenue Service for its 2004 tax year. The audit concernsconcerned the tax treatment of a transaction in September 2004 in which we acquired a portfolio of properties through the acquisition of a limited partnership. On December 17, 2010, the IRS

21


proposed an adjustment to the allocation of recourse liabilities allocated to the contributor of the properties. The Operating Partnership intends to appealhas appealed the proposed adjustment. The proposed adjustment, if upheld, would not result in a material tax liability for us. However, an adjustment could raise a question as to whether a contributor of partnership interests in the 2004 transaction could assert a claim against us under the tax protection agreement entered into as part of the transaction.
Competition for skilled personnel could increase labor costs.
We compete with various other companies in attracting and retaining qualified and skilled personnel. We depend on our ability to attract and retain skilled management personnel who are responsible for the day-to-day operations of our company. Competitive pressures may require that we enhance our pay and benefits package to compete effectively for such personnel. We may not be able to offset such added costs by increasing the rates we charge our tenants. If there is an increase in these costs or if we fail to attract and retain qualified and skilled personnel, our business and operating results could be harmed.
We are dependent upon our key personnel.
We are dependent upon our key personnel whose continued service is not guaranteed. We are dependent on our executive officers for strategic business direction and real estate experience. Loss of their services could adversely affect our operations.

24


Although we have an employment agreement with Gerard H. Sweeney, our President and Chief Executive Officer, this agreement does not restrict his ability to become employed by a competitor following the termination of his employment. We do not have key man life insurance coverage on our executive officers.
Certain limitations will exist with respect to a third party’s ability to acquire us or effectuate a change in control.
Limitations imposed to protect our REIT status. In order to protect us against the loss of our REIT status, our Declaration of Trust limits any shareholder from owning more than 9.8% in value of our outstanding shares, subject to certain exceptions. The ownership limit may have the effect of precluding acquisition of control of us. If anyone acquires shares in excess of the ownership limit, we may:

consider the transfer to be null and void;
not reflect the transaction on our books;
institute legal action to stop the transaction;
not pay dividends or other distributions with respect to those shares;
not recognize any voting rights for those shares; and
consider the shares held in trust for the benefit of a person to whom such shares may be transferred.
Limitation due to our ability to issue preferred shares.Our Declaration of Trust authorizes our Board of Trustees to cause us to issue preferred shares, without limitation as to amount and without shareholder consent. Our Board of Trustees is able to establish the preferences and rights of any preferred shares issued and these shares could have the effect of delaying or preventing someone from taking control of us, even if a change in control were in our shareholders’ best interests.
Limitation imposed by the Maryland Business Combination Law. The Maryland General Corporation Law, as applicable to Maryland REITs, establishes special restrictions against “business combinations” between a Maryland REIT and “interested shareholders” or their affiliates unless an exemption is applicable. An interested shareholder includes a person, who beneficially owns, and an affiliate or associate of the trust who, at any time within the two-year period prior to the date in question, was the beneficial owner of, ten percent or more of the voting power of our then-outstanding voting shares. Among other things, Maryland law prohibits (for a period of five years) a merger and certain other transactions between a Maryland REIT and an interested shareholder unless the board of trustees had approved the transaction before the party became an interested shareholder. The five-year period runs from the most recent date on which the interested shareholder became an interested shareholder. Thereafter, any such business combination must be recommended by the board of trustees and approved by two super-majority shareholder votes unless, among other conditions, the common shareholders receive a minimum price for their shares and the consideration is received in cash or in the same form as previously paid by the interested shareholder for our shares or unless the board of trustees approved the transaction before the party in question became an interested shareholder. The business combination statute could have the effect of discouraging offers to acquire us and of increasing the difficulty of consummating any such offers, even if the acquisition would be in our shareholders’ best interests.
Maryland Control Share Acquisition Act. Maryland law provides that “control shares” of a REIT acquired in a “control share acquisition” shall have no voting rights except to the extent approved by a vote of two-thirds of the vote eligible to be cast on the matter under the Maryland Control Share Acquisition Act. “Control Shares” means shares that, if aggregated with all other shares previously acquired by the acquirer or in respect of which the acquirer is able to exercise or direct the exercise of voting power (except

(except solely by virtue of a revocable proxy), would entitle the acquirer to exercise voting power in electing trustees within one of the following ranges of voting power: one-tenth or more but less than one-third, one-third or more but less than a majority or a majority or more of all voting power. Control shares do not include shares the acquiring person is then entitled to vote as a result of having previously obtained shareholder approval. A “control share acquisition” means the acquisition of control shares, subject to certain exceptions. If voting rights or control shares acquired in a control share acquisition are not approved at a shareholder’s meeting, then subject to certain conditions and limitations the issuer may redeem any or all of the control shares for fair value. If voting rights of such control shares are approved at a shareholder’s meeting and the acquirer becomes entitled to vote a majority of the shares entitled to vote, all other shareholders may exercise appraisal rights. Any control shares acquired in a control share acquisition which are not exempt under our Bylaws are subject to the Maryland Control Share Acquisition Act. Our Bylaws contain a provision exempting from the control share acquisition statute any and all acquisitions by any person of our shares. We cannot assure you that this provision will not be amended or eliminated at any time in the future.

Advance Notice Provisions for Shareholder Nominations and Proposals.Our bylaws require advance notice for shareholders to nominate persons for election as trustees at, or to bring other business before, any meeting of our shareholders. This bylaw provision limits the ability of shareholders to make nominations of persons for election as trustees or to introduce other proposals unless we are notified in a timely manner prior to the meeting.
Many factors can have an adverse effect on the market value of our securities.
A number of factors might adversely affect the price of our securities, many of which are beyond our control. These factors include:

increases in market interest rates, relative to the dividend yield on our shares. If market interest rates go up, prospective purchasers of our securities may require a higher yield. Higher market interest rates would not, however, result in more funds for us to distribute and, to the contrary, would likely increase our borrowing costs and potentially decrease funds available for distribution. Thus, higher market interest rates could cause the market price of our common shares to go down;
anticipated benefit of an investment in our securities as compared to investment in securities of companies in other industries (including benefits associated with tax treatment of dividends and distributions);
perception by market professionals of REITs generally and REITs comparable to us in particular;
level of institutional investor interest in our securities;
relatively low trading volumes in securities of REITs;
our results of operations and financial condition; and
investor confidence in the stock market generally.
The market value of our common shares is based primarily upon the market’s perception of our growth potential and our current and potential future earnings and cash distributions. Consequently, our common shares may trade at prices that are higher or lower than our net asset value per common share. If our future earnings or cash distributions are less than expected, it is likely that the market price of our common shares will diminish.
Additional issuances of equity securities may be dilutive to shareholders.
The interests of our shareholders could be diluted if we issue additional equity securities to finance future developments or acquisitions or to repay indebtedness. Our Board of Trustees may authorize the issuance of additional equity securities without shareholder approval. Our ability to execute our business strategy depends upon our access to an appropriate blend of debt financing, including unsecured lines of credit and other forms of secured and unsecured debt, and equity financing, including the issuance of common and preferred equity.
The issuance of preferred securities may adversely affect the rights of holders of our common shares.
Because our Board of Trustees has the power to establish the preferences and rights of each class or series of preferred shares, we may afford the holders in any series or class of preferred shares preferences, distributions, powers and rights, voting or otherwise, senior to the rights of holders of common shares. Our Board of Trustees also has the power to establish the preferences and rights of each class or series of units in Brandywine Operating Partnership, and may afford the holders in any series or class of preferred units preferences, distributions, powers and rights, voting or otherwise, senior to the rights of holders of common units.
The acquisition of new properties or the development of new properties which lack operating history with us may give rise to difficulties in predicting revenue potential.
We may continue to acquire additional properties and may seek to develop our existing land holdings strategically as warranted by market conditions. These acquisitions and developments could fail to perform in accordance with expectations. If we fail to

23

Table of Contents

accurately estimate occupancy levels, operating costs or costs of improvements to bring an acquired property or a development property up to the standards established for our intended market position, the performance of the property may be below expectations. Acquired properties may have characteristics or deficiencies affecting their valuation or revenue potential that we have not yet discovered. We cannot assure you that the performance of properties acquired or developed by us will increase or be maintained under our management.

26


Our performance is dependent upon the economic conditions of the markets in which our properties are located.
Our properties are located in Pennsylvania, New Jersey, Delaware, Maryland, Virginia, Texas, and California. Like other real estate markets, these commercial real estate markets have been impacted by the sluggish economic recovery from the recent recession, and any adverse changes in economic conditions in the future in any of these economies or real estate markets could negatively affect cash available for distribution. Our financial performance and ability to make distributions to our shareholders will be particularly sensitive to the economic conditions in these markets. The local economic climate, which may be adversely impacted by business layoffs or downsizing, industry slowdowns, changing demographics and other factors, and local real estate conditions, such as oversupply of or reduced demand for office, industrial and other competing commercial properties, may affect revenues and the value of properties, including properties to be acquired or developed. We cannot assure you that these local economies will grow in the future.

(a)
During 2010,2011, we recorded depreciation expenseadditional income of $1.2$0.5 million related to projects completedelectricity charges in prior years that were not closed out of our job cost system inunder-billed to a timely manner.certain tenant. This resulted in the overstatement of total revenue by $0.5 million during the current year and in the understatement of depreciationtotal revenue by $0.3 million and amortization expense in the prior years. During$0.2 million for the years ended December 31, 2009 and 2008 depreciation expense was understated by $0.9 million and $0.2 million,, respectively. The remaining difference relates to other prior years andBecause this error was nominal. As these errors, both individually and in aggregate, were not material to prior years’years' consolidated financial statements and the impact of correcting thisrecording the error in the current year is not material to the our full year consolidated financial statements, we recorded the related adjustmentsadjustment in the current year.

(b)
The consolidated statement of operations during 2011 also contained an out of period depreciation and amortization expense adjustment of $4.7 million relating to intangible assets representing tenant relationships and in-place leases that should have been written off in prior periods. Our recognition of this expense in 2011 resulted in the overstatement of depreciation and amortization expense by $4.7 million million in 2011. During the year ended December 31, 2010, depreciation and amortization expense was overstated by $1.7 million and was understated by $1.4 million, $1.8 million, $1.7 million and $1.5 million during the years ended December 31, 2009, 2008, 2007, and 2006, respectively. As this error was not material to prior years' consolidated financial statements and that the impact of recording the error in the current year is not material to our consolidated financial statements, we recorded the related adjustment during the current year.

Item 7.
Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion should be read in conjunction with the consolidated financial statements appearing elsewhere herein and is based primarily on our consolidated financial statements for the years ended December 31, 2011, 2010 2009 and 2008.2009.

OVERVIEW
As of December 31, 2010,2011, we manage our portfolio within seven segments: (1) Pennsylvania Suburbs, (2) Philadelphia CBD, (3) Metropolitan Washington D.C, (4) New Jersey/Delaware, (5) Richmond, Virginia, (6) Austin, Texas and (7) California. The Pennsylvania Suburbs segment includes properties in Chester, Delaware, and Montgomery counties in the Philadelphia suburbs. The Philadelphia CBD segment includes properties located in the City of Philadelphia in Pennsylvania. The Metropolitan Washington, D.C. segment includes properties in Northern Virginia and suburban Maryland. The New Jersey/Delaware segment includes properties in Burlington, Camden and Mercer counties in New Jersey and in New Castle county in the state of Delaware. The Richmond, Virginia segment includes properties primarily in Albemarle, Chesterfield, Goochland and Henrico counties and Durham, North Carolina. The Austin, Texas segment includes properties in Austin. The California segment includes properties in Oakland, Concord, Carlsbad and Rancho Bernardo.
We generate cash and revenue from leases of space at our properties and, to a lesser extent, from the management of properties owned by third parties and from investments in the Real Estate Ventures. Factors that we evaluate when leasing space include rental rates, costs of tenant improvements, tenant creditworthiness, current and expected operating costs, the length of the lease, vacancy levels and demand for office and industrial space. We also generate cash through sales of assets, including assets that we do not view as core to our portfolio, either because of location or expected growth potential, and assets that are commanding premium prices from third party investors.
Factors that May Influence Future Results of Operations
Global Market and Economic Conditions
In the U.S., market and economic conditions have been unprecedented and challenging, characterized by tighter credit conditions and slower growth. As a result, of these market conditions, the cost and availability of credit has been and may continue to be adversely affected by illiquid credit markets and wider credit spreads. Concern about the stability of the markets generally and the strength of counterparties specifically has led many lenders and institutional investors to reduce, and in some cases, cease to provide funding to borrowers. Continued volatility in the U.S. and international markets and economies may adversely affect our liquidity and financial condition, and the liquidity and financial condition of our tenants. If these market conditions continue, they may limit our ability and the ability of our tenants, to timely refinance maturing liabilities and access the capital markets to meet liquidity needs.
Real Estate Asset Valuation
General economic conditions and the resulting impact on market conditions or a downturn in tenants’ businesses may adversely affect the value of our assets. Significantly challenging economic conditions in the U.S., declining demand for leased office, mixed use, or industrial properties and/or a decrease in market rental rates and/or market values of real estate assets in our submarkets could have a negative impact on the value of our assets, including the value of our properties and related tenant improvements. If we were required under GAAP to write down the carrying value of any of our properties to the lower of cost or fair value due to impairment, or if as a result of an early lease termination we were required to remove or dispose of material amounts of tenant improvements that are not reusable to another tenant, our financial condition and results of operations wouldcould be negatively affected.

42


Leasing Activity and Rental Rates
The amount of net rental income generated by our properties depends principally on our ability to maintain the occupancy rates of currently leased space and to lease currently available space, newly developed or redeveloped properties and space available from unscheduled lease terminations. The amount of rental income we generate also depends on our ability to maintain or increase rental rates in our submarkets. Negative trends in one or more of these factors could adversely affect our rental income in future periods.
Development and Redevelopment Programs
Historically, a significant portion of our growth has come from our development and redevelopment efforts. We have a proactive planning process by which we continually evaluate the size, timing, costs and scope of our development and redevelopment programs and, as necessary, scale activity to reflect the economic conditions and the real estate fundamentals that exist in our

40


strategic submarkets. Given the economic conditions, we doWe are not intend to commence newcurrently proceeding on any development or redevelopment projectsactivity, although, we are, in the near future.ordinary course of business, evaluating development and redevelopment opportunities. We believe that a portion of our future potential growth will continue to come from our newlythe developed or redeveloped properties that we recently placed in service once current economic conditions normalize. However, we anticipate that the general economic conditions and the resulting impact on conditions in our core markets will delay timing and reduce the scope of our development program in the near future, which will further impact the average development and redevelopment asset balances qualifying for interest and other carry cost capitalization. We cease capitalizing such costs once a project does not qualify for interest and other carry cost capitalization under GAAP.future.
In addition, we may be unable to lease committed development or redevelopment properties at expected rental rates or within projected timeframes or complete development or redevelopment properties on schedule or within budgeted amounts, which could adversely affect our financial condition, results of operations and cash flow.
Financial and Operating Performance
Our financial and operating performance is dependent upon the demand for office, industrial and other commercial space in our markets, our leasing results, our acquisition, disposition and development activity, our financing activity, our cash requirements and economic and market conditions, including prevailing interest rates.
Volatile economic conditions could result in a reduction of the availability of financing and potentially in higher borrowing costs. These factors, coupled with a sluggish economic recovery, have reduced the volume of real estate transactions and created credit stresses on most businesses. Vacancy rates may increase, and rental rates may decline, through 2012 and possibly beyond as the current economic climate negatively impacts tenants.

We expect that the impact of the current state of the economy, including high unemployment and the unprecedented volatility in the financial and credit markets, will continue to have a dampening effect on the fundamentals of our business, including increases in past due accounts, tenant defaults, lower occupancy and reduced effective rents. These conditions would negatively affect our future net income and cash flows and could have a material adverse effect on our financial condition. We believe that the quality of our assets and our strong balance sheet will enable us to raise debt capital, if necessary, in various forms and from different sources, including traditional term or secured loans from banks, pension funds and life insurance companies. However, there can be no assurance that we will be able to borrow funds on terms that are economically attractive or at all.
We seek revenue growth throughout our portfolio by increasing occupancy and rental rates. Occupancy at our wholly owned properties at December 31, 2011 was 86.5%.
The table below summarizes selected operating and leasing statistics of our wholly owned operating properties for the year ended December 31, 2011:

(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.

41


Tenant Rollover Risk:
We are subject to the risks that tenant leases, upon expiration, are not renewed, that space may not be relet; and that the terms of renewal or reletting (including the cost of renovations) may be less favorable to us than the current lease terms. Leases accounting for approximately 8.8%9.5% of our aggregate final annualized base rents as of December 31, 20102011 (representing approximately 8.6%8.7% of the net rentable square feet of the properties) expire without penalty in 2011.2012. We maintain an active dialogue with our tenants in an effort to maximize lease renewals. Our retention rate for leases that were scheduled to expire in 20102011 was 65.9%65.2%. 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 regularly evaluates our accounts receivable reserve policy in light of our tenant base and general and local economic conditions. Our accounts receivable allowance was $15.2$15.5 million or 12.0%11.2% of total receivables (including accrued rent receivable) as of December 31, 20102011 compared to $16.4$15.2 million or 14.3%12.0% of total receivables (including accrued rent receivable) as of December 31, 2009.2010.
If economic conditions persist or deteriorate further, 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.

43


Development Risk:
At December 31, 2010, we were redeveloping one garage project located in Philadelphia with total projected costs of $14.8 million of which $0.8 million then remained to be funded. In addition,2011, we were completing the lease-up of fivefour recently completed developments, aggregating 0.90.7 million square feet, for which we expect to spend an additional $14.2$8.5 million in 2011.2012. We are actively marketing space at these projects to prospective tenants but can provide no assurance as to the timing or terms of any leases of space at these projects.
As of December 31, 2010,2011, we owned approximately 509444 acres of undeveloped land, and held options to purchase approximately 52 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 the parcels of land that we ultimately develop, we will be subject to risks and costs associated with land development, of this land including construction cost increases or overruns and construction delays, insufficient occupancy rates, building moratoriums and inability to obtain necessary zoning, land-use, building, occupancy and other required governmental approvals.approvals, construction cost increases or overruns and construction delays, and insufficient occupancy rates and rental rates. We have entered into development agreements related to two of our land parcels under option for ground lease that require us to commence development by December 31, 2012. If we determine that we will not be able to start the construction by the date specified, or if we determine that development is not in our best economic interest and an extension of the development period cannot be negotiated, we will write off all costs that we have incurred in preparing these parcels of land for development amounting to $7.7 million as of December 31, 2011.

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 financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the reporting periods. 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 the accounting estimate are reasonably likely to occur from period to period. Management believes the following critical accounting policies reflect our more significant judgments and estimates used in the preparation of our consolidated financial statements. For a summary of all of our significant accounting policies, see Note 2 to our consolidated financial statements included elsewhere in this report.
Revenue Recognition
We recognize rental revenue on the straight-line basis from the later of the date of the commencement of the lease or the date of acquisition of the property subject to existing leases, which averages minimum rents over the terms of the leases. Lease incentives, which are included as reductions of rental revenue are recognized on a straight-line basis over the term of the lease. Certain lease agreements contain provisions that require tenants to reimburse a pro rata share of real estate taxes and common area maintenance costs. For certain leases in the portfolio, there are significant assumptions and judgments made by management in determining the lease term such as when termination options are provided to the tenant. The lease term impacts the period over which minimum

42


rents are determined and recorded and also considers the period over which lease related costs are amortized. In addition, our rental revenue is impacted by our determination of whether the improvements made by us or the tenant are landlord assets. The determination of whether an asset is a landlord asset requires judgment and principally considers whether improvements would be utilizable by another tenant upon move out by the existing tenant. To the extent they are determined not to be landlord assets, and we fund them, they are considered as lease incentives. To the extent the tenant funds the improvements that we consider to be landlord assets, we treat them as deferred revenue which is amortized to revenue over the lease term.
Real Estate Investments
Real estate investments are carried at cost. We record acquisition of real estate investments under the acquisition method of accounting and allocate the purchase price to land, buildings and intangible assets on a relative fair value basis. Depreciation is computed using the straight-line method over the useful lives of buildings and capital improvements (5 to 55 years) and over the shorter of the lease term or the life of the asset for tenant improvements. Direct construction costs related to the development of Properties and land holdings are capitalized as incurred. Capitalized costs include pre-construction costs essential to the development of the property, development and constructions costs, interest, property taxes, insurance, salaries and other project costs during the period of development. Estimates and judgments are required in determining when capitalization of certain costs such as interest should commence and cease. We expense routine repair and maintenance expenditures and capitalize those items that extend the useful lives of the underlying assets.

44


Real Estate Ventures
When we obtain an economic interest in an entity, we evaluate the entity to determine if the entity is deemed a variable interest entity (“VIE”), and if we are deemed to be the primary beneficiary, in accordance with the accounting standard for the consolidation of variable interest entities. This accounting standard requires significant use of judgments and estimates in determining its application. If the entity is not deemed to be a VIE, and we serve as the general partner within the entity, we evaluate to determine if our presumed control as the general partner is overcome by the “kick out” rights and other substantive participating rights of the limited partners in accordance with the same accounting standard.
We consolidate (i) entities that are VIEs and of which we are deemed to be the primary beneficiary and (ii) entities that are non-VIEs which we control. Entities that we account for under the equity method (i.e., at cost, increased or decreased by our share of earnings or losses, less distributions) include (i) entities that are VIEs and of which we are not deemed the primary beneficiary (ii) entities that are non-VIEs which we do not control, but over which we have the ability to exercise significant influence and (iii) entities that are non-VIEs which we control through our general partner status, but in which the limited partners in the entity have the substantive ability to dissolve the entity or remove us without cause or have substantive participating rights. We continuously assess our determination of whether an entity is a VIE and who the primary beneficiary is, and whether or not the limited partners in an entity have substantive rights, more particularlyincluding if certain events occur that are likely to cause a change in original determinations.
On a periodic basis, management assesses whether there are any indicators that the value of our investments in unconsolidated joint ventures may be impaired. An investment is impaired only if management’s estimate of the value of the investment is less than the carrying value of the investment, and such decline in value is deemed to be other than temporary. To the extent impairment has occurred, the loss shall be measured as the excess of the carrying amount of the investment over the fair value of the investment. Our estimates of value for each investment (particularly in commercial real estate joint ventures) are based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for tenants, changes in market rental rates, and operating costs. As these factors are difficult to predict and are subject to future events that may alter management’s assumptions; accordingly, the values estimated by management in its impairment analyses may not be realized.
Our Broadmoor Joint Venture owns an office park in Austin, Texas which is currently leased to a single tenant who is also a partner in the joint venture. The said tenant is also the owner of the land which the joint venture currently leases under an existing ground lease agreement. The office buildings’ lease renewals are currently under negotiation. Given the current circumstances, we have performed an impairment assessment of our investment in the venture using probability weighted scenarios that include varying outcomes. We believe that a market participant would assess the probabilities of these outcomes in the same fashion. In evaluating the scenarios, we have determined that the fair value of our investment marginally exceeded its carrying value and the investment is not impaired at December 31, 2010. However, given the lease has not yet been executed and the negotiations of specific terms of the lease are ongoing, the ultimate outcome is uncertain and could cause an impairment of our investment that could be material.
Impairment of Long-Lived Assets
We review long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The review of recoverability is based on an estimate of the future undiscounted cash flows (excluding interest charges) expected to result from the long-lived asset’s use and eventual disposition. These cash flows consider factors such as expected future operating income, trends and prospects, as well as the effects of leasing demand, competition and other factors. If impairment exists due to the inability to recover the carrying value of a long-lived asset, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair-value of the property. We are required to make subjective assessments as to whether there are impairments in the values of the investments in long-lived assets. These assessments have a direct impact on our net income because recording an impairment loss results in an immediate negative adjustment to net income. The evaluation of anticipated cash flows is highly subjective and is based in part on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results in future periods. ThereOperating properties are also operating properties evaluated as if

43


they have been identified for potential sale. No impairment was determined; however, if actual cashflowscash flows or the estimated holding periods change, an impairment could be recorded in the future and it could be material. Although our strategy is generally to hold our properties over the long-term, we will dispose of properties to meet our liquidity needs or for other strategic needs. If our strategy changes or market conditions otherwise dictate an earlier sale date, an impairment loss may be recognized to reduce the property to the lower of the carrying amount or fair value less costs to sell, and such loss could be material. If we determine that impairment has occurred and the assets are classified as held and used, the affected assets must be reduced to their fair-value.

45


Where properties have been identified as having a potential for sale, additional judgments are required related to the determination as to the appropriate period over which the undiscounted cash flows should include the operating cash flows and the amount included as the estimated residual value. Management determines the amounts to be included based on a probability weighted cash flow. This requires significant judgment. In some cases, the results of whether an impairment is indicated are sensitive to changes in assumptions input into the estimates, including the hold period until expected sale. At December 31, 2010,2011, we performed an impairment assessment of our land holdings as management determined that a sale scenario was the most likely source of future cash flows for certain of the land parcels aggregating to total cost of $15.7$12.2 million which is included in land inventory. This impairment assessment required management to estimate the expected proceeds from sale at some point in the future, to determine whether an impairment was indicated. This estimate requires significant judgment. If our expectations as to the expected sales proceeds, or timing of the anticipated sale change based on market conditions or otherwise, our evaluation of impairment could be different and such differences could be material.material to the operations of the Company.
During our impairment review for 2011 and 2010, we determined that no impairment charges were necessary. During the first quarter of 2009, we determined that one of our properties, during our testing for impairment under the held and used model, had a historical cost greater than the probability-weighted undiscounted cash flows. Accordingly, an impairment on the property of $3.7 million was recorded to reduce its carrying value to an amount equal to management’s estimate of the then current fair value. We sold this property in the second quarter of 2009. We also recorded a $6.85 million impairment charge on properties designated as held for sale at June 30, 2008, and sold these properties during the fourth quarter of 2008.
We also entered into development agreements related to our two parcels of land under option for ground lease that require us to commence development by December 31, 2012. If we determine that we will not be able to start the construction by the date specified, or if we determine development is not in our best economic interest and an extension of the development period cannot be negotiated, we will have to write off all costs that we have incurred in preparing these parcels of land for development amounting to $7.7$7.7 million as of December 31, 2010.2011.
Income Taxes
Parent Company
The Parent Company has elected to be treated as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”). In addition, the Parent Company has several subsidiarymay elect to treat one or more of its subsidiaries as REITs. In order to continue to qualify as a REIT, the Parent Company and each of its REIT subsidiaries are required to, among other things, distribute at least 90% of their REIT taxable income to their stockholders and meet certain tests regarding the nature of its income and assets. As REITs, the Parent Company and its REIT subsidiaries are not subject to federal income tax with respect to the portion of their income that meets certain criteria and is distributed annually to the stockholders. Accordingly, no provision for federal income taxes is included in the accompanying consolidated financial statements with respect to the operations of these REITs. The Parent Company and its REIT subsidiaries, if any, intend to continue to operate in a manner that allows them to continue to meet the requirements for taxation as REITs. Many of these requirements, however, are highly technical and complex. If the Parent Company or one of its REIT subsidiaries were to fail to meet these requirements, they would be subject to federal income tax.
The Parent Company may elect to treat one or more of its subsidiaries as a TRS. In general, a TRS may perform additional services for our tenants and generally may engage in any real estate or non-real estate related business (except for the operation or management of health care facilities or lodging facilities or the provision to any person, under a franchise, license or otherwise, of rights to any brand name under which any lodging facility or health care facility is operated). A TRS is subject to corporate federal income tax. The Parent Company has elected to treat certain of its corporate subsidiaries as TRSs; these entities provide third party property management services and certain services to tenants that could not otherwise be provided.
Operating Partnership
In general, the Operating Partnership is not subject to federal and state income taxes, and accordingly, no provision for income taxes has been made in the accompanying consolidated financial statements. The partners of the Operating Partnership are required to include their respective share of the Operating Partnership’s profits or losses in their respective tax returns. The Operating Partnership’s tax returns and the amount of allocable Partnership profits and losses are subject to examination by federal and state taxing authorities. If such examination results in changes to the Operating Partnership profits or losses, then the tax liability of the partners would be changed accordingly.

46


The Operating Partnership has electedmay elect to treat one or several of its subsidiaries as REITs under Sections 856 through 860 of the Code. Each subsidiary REIT has met or intends to meet the requirements for treatment as a REIT under Sections 856 through 860

44


of the Code, and, accordingly, no provision has been made for federal and state income taxes in the accompanying consolidated financial statements. If any subsidiary REIT fails to qualify as a REIT in any taxable year, that subsidiary REIT will be subject to federal and state income taxes and may not be able to qualify as a REIT for the four subsequent taxable years. Also, each subsidiary REIT may be subject to certain local income taxes.
The Operating Partnership has elected to treat several of its subsidiaries as taxable TRSs, which are subject to federal, state and local income tax.
Allowance for Doubtful Accounts
We maintain an allowance for doubtful accounts that represents an estimate of losses that may be incurred from the inability of tenants to make required payments. The allowance is an estimate based on two calculations that are combined to determine the total amount reserved. First, we evaluate specific accounts where we have determined that a tenant may have an inability to meet its financial obligations. In these situations, we use our judgment, based on the facts and circumstances, and record a specific reserve for that tenant against amounts due to reduce the receivable to the amount that we expect to collect. These reserves are re-evaluated and adjusted as additional information becomes available. Second, a reserve is established for all tenants based on a range of percentages applied to receivable aging categories. If the financial condition of our tenants were to deteriorate, additional allowances may be required. For accrued rent receivables, we consider the results of the evaluation of specific accounts as well as other factors including assigning risk factors to different industries based on our tenants SIC classification. Considering various factors including assigning a risk factor to different industries, these percentages are based on historical collection and write-off experience adjusted for current market conditions.
Deferred Costs
We incur direct costs related to the financing, development and leasing of our properties. Management exercises judgment in determining whether such costs, particularly internal costs, meet the criteria for capitalization or must be expensed. Capitalized financing fees are amortized over the related loan term on a basis that approximates the effective interest method while capitalized leasing costs are amortized over the related lease term. Management re-evaluates the remaining useful lives of leasing costs as the creditworthiness of our tenants and economic and market conditions change.
Purchase Price Allocation
We allocate the purchase price of properties to net tangible and identified intangible assets acquired based on fair values. Above-market and below-market in-place lease values for acquired properties are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) our estimate of the fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancellable term of the lease (includes the below market fixed renewal period, if applicable). Capitalized above-market lease values are amortized as a reduction of rental income over the remaining non-cancellable terms of the respective leases. Capitalized below-market lease values are amortized as an increase of rental income over the remaining non-cancellable terms of the respective leases, including any fixed-rate renewal periods.

47


Other intangible assets also include amounts representing the value of tenant relationships and in-place leases based on our evaluation of the specific characteristics of each tenant’s lease and our overall relationship with the respective tenant. We estimate the cost to execute leases with terms similar to the remaining lease terms of the in-place leases, include leasing commissions, legal and other related expenses. This intangible asset is amortized to expense over the remaining term of the respective leases and any fixed-rate bargain renewal periods. We estimate fair value through methods similar to those used by independent appraisers or by using independent appraisals. Factors that we consider in our analysis include an estimate of the carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. We also consider information obtained about each property as a result of our pre-acquisition due diligence, marketing and leasing activities in estimating the fair value of the tangible and intangible assets acquired. In estimating carrying costs, we include real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, which primarily range from three to twelve months.
Characteristics that we consider in allocating value to our tenant relationships include the nature and extent of our business relationship with the tenant, growth prospects for developing new business with the tenant, the tenant���stenant’s credit quality and expectations of lease renewals. The value of tenant relationship intangibles is amortized over the remaining initial lease term and expected renewals, but in no event longer than the remaining depreciable life of the building. The value of in-place leases is amortized over the remaining non-cancellable term of the respective leases and any fixed-rate renewal periods.
In the event that a tenant terminates its lease prior to the end of the lease term, the unamortized portion of each intangible, including

45


market rate adjustments, in-place lease values and tenant relationship values, would be charged to expense.

RESULTS OF OPERATIONS
The following discussion is based on our Consolidated Financial Statements for the years ended December 31, 2011, 2010 and 2009. We believe that the 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 defined as total revenue less operating expenses, real estate taxes and third party management expenses. 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 18 to the 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 also reflect general and administrative expenses, interest expenses, real estate impairment losses, depreciation and amortization costs, capital expenditures and leasing costs, or trends in development and construction activities that could materially impact our results from operations. We believe that net income, as defined by GAAP, is the most appropriate earnings measure. See Note 18 to the Consolidated Financial Statements for a reconciliation of NOI to our consolidated net loss.
Comparison of the Year Ended December 31, 20102011 to the Year Ended December 31, 20092010
The table below shows selected operating information for the “Same Store Property Portfolio” and the “Total Portfolio.” The Same Store Property Portfolio consists of 223 properties containing an aggregate of approximately 22.322.2 million net rentable square feet that we owned for the entire twelve-month periods ended December 31, 2011 and 2010. The Same Store Property Portfolio includes properties acquired or placed in service on or prior to January 1, 2010 and 2009.owned through December 31, 2011. The Total Portfolio includes the effects of other properties that were either placed into service, acquired or redeveloped after January 1, 2010 or disposed of prior to December 31, 2011. 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 twelve-month periods ended December 31, 20102011 and 2009)2010) by providing information for the properties which were acquired, under development (including lease-up assets) or placed into service and administrative/elimination information for the twelve-month periods ended December 31, 2011 and 2010 (in thousands).
The Total Portfolio net income presented in the table is equal to the net income of Brandywine Realty Trust and Brandywine Operating Partnership, L.P.

(a)- Represents certain revenues and expenses at the corporate level as well as various intercompany costs that are eliminated in consolidation and third-party management fees. This also includes two properties that were contributed to an unconsolidated real estate venture in which the Company has a 50% ownership interest (see Note 3 for additional information).

47


Total Revenue
Cash rents from the Total Portfolio increased by $13.5 million from 2010 to 2011, primarily reflecting:

increase of $30.1 million in rental income due to our acquisition of Three Logan Square, the completion and placement in service of the IRS Philadelphia Campus and Cira South Garage during the third quarter of 2010, the acquisition of Overlook I and II during the first quarter of 2011, the placement in service of the Juniper Street Parking Garage during the second quarter of 2011, and the acquisition of 3020 Market Street during the third quarter of 2011; and
offsetting decrease of $16.6 million of rental income at the same store and corporate-level portfolio's as a result of declining renewal rates and the commencement of leases with free rent periods during 2011 compared to 2010.

Straight-line rents increased by $6.5 million due to the aforementioned properties that were acquired and placed in service in 2011 and also due to leases that commenced during 2011 with free rent periods at our same store properties.
Tenant reimbursements increased by $4.1 million from 2010 to 2011 primarily due to $6.6 million of additional reimbursements from the aforementioned properties that were acquired and placed in service during 2011. These increases were offset by a $2.5 million decrease in tenant reimbursements in our same store portfolio resulting from decreases in property operating expenses at our same store portfolio. These changes in tenant reimbursements are consistent with the changes in property operating expenses and real estate taxes.
Termination fees at the Total Portfolio decreased by $2.6 million from 2010 to 2011 mainly due to timing and volume of tenant move-outs during 2011.
Other Income
Other Income increased by $1.1 million mainly as a result of the expiration of a third party purchase option on a parcel of land in the Pennsylvania suburbs that was entered into during March of 2007. Upon expiration of this purchase option, we recognized the value of the option as other income.
Property Operating Expenses

Property operating expenses at the Total Portfolio increased by $4.1 million, mainly due to $11.6 million of additional expenses from the aforementioned properties that we acquired and placed in service during 2011. This increase was offset by the decreases in repairs and maintenance costs of $4.5 million, utilities costs of $1.2 million, and bad debt expense of $2.0 million during 2011 compared to 2010 within our same store portfolio. The reduction in repairs and maintenance costs are a result of contract negotiations that took place across our portfolio during 2011. The reduction in utilities costs reflects our entry in 2011 into two year contracts at lower prices within our Pennsylvania and New Jersey portfolios. Bad debt expense decreased as a result of fewer early lease terminations during 2011 compared to 2010 with such terminations requiring the write off to bad debt expense of any remaining straight line receivable balances.
Real Estate Taxes

Real estate taxes increased by $2.7 million, mainly due to additional real estate taxes from the aforementioned properties that we acquired and placed into service during 2011.
General & Administrative Expenses
General and Administrative Expense increased by $1.3 million primarily due to:

an increase of $0.8 million in benefits claims expense as a result of more insurance claims being made compared to the prior year; and
a decrease in capitalized salaries of $0.8 million due to less construction activity compared to the prior year

These increases were offset by a decrease of $0.3 million in various corporate level expenses during 2011, none of which were individually significant.
Depreciation and Amortization Expense
Depreciation and amortization increased by $7.1 million from 2010 to 2011, primarily due to the additional $15.3 million of depreciation and amortization expense from the aforementioned properties that we acquired and placed into service during 2011.

48


We also recorded $4.7 million of an out of period depreciation and amortization expense adjustment during the second quarter of 2011 for intangible assets representing tenant relationships and in-place leases that should have been written off in prior years (see Note 2 to the consolidated financial statements). These increases were offset by $12.9 million in expense decreases related to asset write-offs related to early move-outs and fully amortized assets in 2010, without comparable expenses in 2011.

Interest Income

Interest income decreased by $1.4 million, primarily due to our receipt during the third quarter of 2010 of the repayment of the $40.0 million purchase money mortgage note that we extended to the buyer of our properties in Oakland, California in October 2008.

Historic tax credit transaction income

During the third quarter of 2011, we recognized $12.0 million of income related to our historic tax credit financing. We expect to recognize approximately the same amount of income each year over the remaining four year tax credit recapture period as defined in the Code. See Note 16 to the consolidated financial statements for additional details of our historic tax credit transaction.
Interest Expense

The decrease in interest expense of $1.2 million is primarily due to the following:

decrease of $10.6 million related to our $300.0 million 5.625% Guaranteed Notes that matured during December of 2010;
decrease of $7.5 million as a result of our prior year hedges maturing during the fourth quarter of 2010;
decrease of $2.0 million related to the repurchase of our $345.0 million 3.875% Guaranteed exchangeable notes;
decrease of $1.1 million in mortgage interest expense which is directly related to the $199.8 million decrease in mortgage indebtedness during the year ended December 31, 2011; and,
decrease of $1.3 million resulting from our buybacks of unsecured notes during 2011. The details of various repurchases made during 2011 are noted in "Gain (loss) on early extinguishment of debt" section below.

The decrease of $22.5 million in interest expense described above was offset by the following increases in interest expense during 2011 compared to 2010:

increase of $12.3 million related our issuance in April 2011 of $325.0 million 4.950% Guaranteed Notes due 2018;
decrease of $8.4 million of capitalized interest expense as a result of lower development activity during 2011;
increase of $0.3 million related to the Historic Tax Credit interest accretion. We accrete interest related to the preferred return due to our partner in the Philadelphia IRS Campus transaction; and,
increase of $0.3 million of interest on our Credit Facility due to a higher outstanding balance during 2011 compared to 2010.

Interest Expense - Amortization of Deferred Financing Costs

The increase in amortization of deferred financing costs of $1.2 million is mainly attributable to the acceleration of $0.8 million of deferred financing costs in connection with the mortgage debt prepayments we made during 2011. The remainder of the increase is due to the closing of the forward financing on the IRS Philadelphia Campus and Cira South Garage during the third quarter of 2010.
Equity in income of real estate ventures
The decrease in equity in income of real estate ventures of $1.5 million is primarily due to lower net income at the real estate venture properties during 2011 compared to 2010 and the recognition of $0.5 million of acquisition costs related to a real estate venture formed during the fourth quarter of 2011. These decreases were offset by $0.6 million of income from the sale of a building to one of the unconsolidated real estate ventures and by $0.5 million of preferred returns from the two unconsolidated real estate ventures in which we acquired a 25% interest during the third quarter of 2010 (see Note 4 of the notes to the consolidated financial statements for details of these two transactions).
Net gain on sales of interest in real estate
During the year ended December 31, 2011, we recognized a $2.8 million net gain upon the sale of the remaining 11% ownership interest in three properties that we partially sold to one of our unconsolidated Real Estate Ventures in December 2007. We had

49


retained an 11% equity interest in these properties subject to a put/call at fixed prices for a period of three years from the time of the sale. In January 2011, we exercised the put/call which then transferred full ownership in the three properties to the Real Estate Venture. Accordingly, our direct continuing involvement through our 11% interest in the properties ceased as a result of the transfer of the ownership interest.
Gain (loss) on early extinguishment of debt

During 2011, we repurchased (i) $23.7 million of our 5.750% Guaranteed Notes due 2012 and (ii) $22.7 million of our 7.500% Guaranteed Notes due 2015, which resulted in a net loss on early extinguishment of debt of $3.3 million. The loss was offset by the write-off of the unamortized fixed-rate debt premium of $0.5 million related to the prepayment of two of our mortgage loans during 2011.
During 2010, we repurchased (i) $68.1 million of our $345.0 million 3.875% Exchangeable Notes, (ii) $1.9 million of our $300.0 million 5.625% Guaranteed Notes due 2010 and (iii) $12.6 million of our $300.0 million 5.750% Guaranteed Notes due 2012 which resulted in a net loss on early extinguishment of debt of $2.2 million. The net loss was offset by a gain from the write-off of the remaining premium on the Plymouth Meeting Executive Campus ("PMEC") note at the time of pay-off of $0.1 million resulting in an aggregate net loss on early extinguishment of debt of $2.1 million.
Discontinued Operations
During 2011, we sold three properties in Marlton, New Jersey, and one property in Exton, PA. These properties had total revenues of $5.0 million, operating expense of $2.3 million and $1.4 million of depreciation and amortization expense. We recognized a gain on sale of these properties of $7.3 million.
The amounts for the year ended December 31, 2010 are reclassified to include the operations of the properties sold during the twelve months period ended December 31, 2011, as well as all properties that were sold through the year ended December 31, 2010. Therefore, the discontinued operations amount for the twelve-month period ended December 31, 2010 includes total revenue of $13.3 million, operating expenses of $6.4 million and depreciation and amortization expense of $4.2 million.
Net Loss
Net loss decreased by $12.9 million from the twelve-month period ended December 31, 2010 as a result of the factors described above. Net income is significantly impacted by depreciation of operating properties and amortization of acquired intangibles. These non-cash charges do not directly affect our ability to pay dividends. Such charges can be expected to continue until lease intangibles are fully amortized. These intangibles are amortizing over the related lease terms or estimated duration of the tenant relationship.
Loss per Common Share
Loss per share (basic and diluted) was $(0.10) for the twelve-month period ended December 31, 2011 as compared to loss per share of $(0.19) for the twelve-month period ended December 31, 2010 as a result of the factors described above and an increase in the average number of common shares outstanding. The increase in the average number of common shares outstanding is primarily due to issuances pursuant to the Offering Program in 2011 and the redemption of 7.1 million of redeemable limited partnership units in exchange for our common shares (see Notes 12 and 13 for additional information).

RESULTS OF OPERATIONS
Comparison of the Year Ended December 31, 2010 to the Year Ended December 31, 2009
The table below shows selected operating information for the “Same Store Property Portfolio” and the “Total Portfolio.” The Same Store Property Portfolio consists of 223 properties containing an aggregate of approximately 22.3 million net rentable square feet that we owned for the entire twelve-month periods ended December 31, 2010 and 2009. The Same Store Property Portfolio includes properties acquired or placed in service on or prior to January 1, 2009 and owned through December 31, 2010. The Total Portfolio includes the effects of other properties that were either placed into service, acquired or redeveloped after January 1, 2009 or disposed prior to December 31, 2010.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 twelve-month periods ended December 31, 2010 and 2009) by providing information for the properties which were acquired, under development (including lease-up assets) or placed into service and administrative/elimination information for the twelve-month periods ended December 31, 2010 and 2009 (in thousands).
The Total Portfolio net income presented in the table is equal to the net income of Brandywine Realty Trust and Brandywine Operating Partnership.

Total Revenue
Cash rents from the Total Portfolio decreased by $10.9 million from 2009 to 2010, primarily reflecting:
decrease of $13.6 million of rental income at the same store portfolio as a result of the decrease in same store occupancy of 320 basis points;
decrease of $7.3 million due to the deconsolidation of three of our real estate ventures as a result of the adoption of the new accounting standard for the consolidation of variable interest entities beginning January 1, 2010 during the first quarter of 2010. This standard does not require retrospective adoption;
decrease of $3.9 million of rental income due to the decrease in occupancy at three redevelopment properties that we recently placed in service; and

decrease of $13.6 million of rental income at the same store portfolio as a result of the decrease in same store occupancy of 320 basis points;
decrease of $7.3 million due to the deconsolidation of three of our real estate ventures as a result of the adoption of the new accounting standard for the consolidation of variable interest entities beginning January 1, 2010 during the first quarter of 2010. This standard does not require retrospective adoption;
decrease of $3.9 million of rental income due to the decrease in occupancy at three redevelopment properties that we recently placed in service; and
an offsetting increase of $13.9 million of rental income due to our acquisition of Three Logan Square and the completion and placement in service of the IRS Philadelphia Campus and the Cira South Garage during the third quarter of 2010.
Straight-line rents at the Total Portfolio increased by $5.0 million due to $1.1 million of straight-line rents from the acquisition of Three Logan Square during the third quarter of 2010. The remainder of the increase is due to leases that commenced during the year of 2010 with free rent periods at our same store properties and at one of our redevelopment properties.
Tenant reimbursements increased by $0.6 million from 2009 to 2010 primarily due to the significant number of leases which includesinclude base year operating expense recovery calculations that reached their base year amounts quicker in 2010 than in 2009. Lease structure, the significant northeast snowfall expenses in the first quarter of 2010, as well as the deferral to later months and timing of the repairs and maintenance expenses in the second quarter of 2009, resulted in the base year leases achieving their base year amounts earlier in 2010 than in 2009. This is consistent with the increase in property operating expenses.
TerminationThe increase in termination fees at the Total Portfolio increasedof $2.2 million from 2009 to 2010 is mainly due to increased tenant move-outs during 2010 which is consistent with the decrease in occupancy noted above.
Third party management fees, labor reimbursement and leasing decreased by $5.3 million from 2009 to 2010 mainly due to the termination of third party management contracts during the course of 2009 totaling 4.3 million square feet. This is consistent with the decrease in third party management fees. This decrease was off-set by the Company no longer eliminating third party management fee income related to two of our real estate ventures of $0.4 million in 2010.
Other Income
Other Income increased by $1.0 million mainly as a result of additional construction management fee income of $0.5 million from our agreement with the GSA relating to the IRS Philadelphia Campus. In addition, we received $0.4 million of proceeds from bankruptcy settlements with two of our former tenants and $0.1 million from a new energy efficiency rebate program in 2010.
Property Operating Expenses
Property operating expenses increased by $5.0 million mainly due to our acquisition of Three Logan Square and the completion and placement in service of the IRS Philadelphia Campus and the Cira South Garage during the third quarter of 2010 totaling $5.3 million of additional expenses. In addition, we incurred higher snow removal and repairs and maintenance expenses totaling $2.1 million during 2010 compared to 2009. This net increase was off-setoffset by a decrease of $2.7 million in bad debt expense during 2010 as compared to 2009.
Real Estate Taxes

Real estate taxes decreased by $2.6 million mainly due to lower taxes assessed on our properties during 2010 compared to 2009 and refunds related to prior years, offset by additional real estate taxes due to our acquisition of Three Logan Square during the third quarter of 2010.

51


General & Administrative Expenses
General and Administrative Expense increased by $2.5 million primarily due to:
an increase of $0.8 million in amortization of stock-based compensation as a result of stock option and restricted stock performance units granted in March 2010;
an increase of $1.4 million in salaries, bonus and recruiting fees due to new hires during 2010;
a $0.2 million one-time bonus payment made during 2010; and
a net increase of $0.1 million as a result of various corporate level expenses during 2010, none of which were individually significant;

an increase of $0.8 million in amortization of stock-based compensation as a result of stock option and restricted stock performance units granted in March 2010;

53


an increase of $1.4 million in salaries, bonus and recruiting fees due to new hires during 2010;
a $0.2 million one-time bonus payment made during 2010; and
a net increase of $0.1 million as a result of various corporate level expenses during 2010, none of which were individually significant.
Depreciation and Amortization Expense
Depreciation and amortization increased by $6.9 million from 2009 to 2010, primarily due to our depreciation and amortization expense on assets placed in service since 2009, particularly Three Logan Square and the IRS Philadelphia Campus which totaled $8.2 million of depreciation and amortization expense. During 2010, we also recorded $1.2 million of depreciation related to 2009 and prior years principally with respect to completed projects that were not closed out of our job cost system timely. This net increase was off-set by a decrease in depreciation and amortization expense from assets written-off related to early move-outs and fully amortized assets when comparing 2010 to 2009.
Provision for Impairment on Real Estate
During our first quarter 2009 impairment review, we determined that one of the properties tested for impairment under the held and used model had a historical cost greater than the probability weighted undiscounted cash flows. Accordingly, the recorded amount was reduced to an amount based on management’s estimate of its fair value.
Where properties have been identified as having a potential for sale, additional judgments are required related to the determination as to the appropriate period over which the undiscounted cash flows should include the operating cash flows and the amount included as the estimated residual value. Management determines the amounts to be included based on a probability weighted cash flow. This requires significant judgment. In some cases, the results of whether an impairment is indicated are sensitive to changes in assumptions input into the estimates, including the hold period until expected sale.
Interest Expense
The decrease in interest expense of $3.1 million is primarily due to the following:

a decrease of $14.6 million resulting from our buybacks of various unsecured notes subsequent to 2009. The details of the various purchases completed during 2010 are noted in the (Loss) gain on early extinguishment of debt section below;
a decrease of $5.5 million resulting from the pay-off of an unsecured note at maturity during the fourth quarter of 2009;
a decrease of $0.4 million resulting from lower weighted average interest rates on our $183.0 million term loan and our three Preferred Trust borrowings. Such borrowings have variable interest rates and a portion of such borrowings are swaps which matured early in the quarters; and
a decrease of $14.6 million resulting from our buybacks of various unsecured notes subsequent to 2009. The details of the various purchases completed during 2010 are noted in the(Loss) gain on early extinguishment of debtsection below;
a decrease of $5.5 million resulting from the pay-off of an unsecured note at maturity during the fourth quarter of 2009;
a decrease of $0.4 million resulting from lower weighted average interest rates on our $183.0 million term loan and our three Preferred Trust borrowings. Such borrowings have variable interest rates and a portion of such borrowings are swaps which matured early in the quarters; and
an increase of $1.5 million in capitalized interest as a result of the increase in cumulative spending on development projects in 2010 compared to 2009.

52


The above described decrease of $22.0 million was offset by an increase of $14.3 million from the sale of $250.0 million of unsecured notes in the third quarter of 2009 and a net increase of $3.4 million resulting from a higher outstanding mortgage notes payable balance as of December 31, 2010 compared to December 31, 2009. We also had an increase of $0.5 million in interest expense related to the interest accretion of the Two Logan Square $2.9 million future liability (expected to be settled in 2019). In addition, there was an increase of $0.6 million in interest expense related to the estimated equity interest payments as a result of our partnership in the IRS Philadelphia Campus.
Deferred financing costs decreased by $2.1 million mainly due to the acceleration of such expenses incurred from greater debt repurchase activities during the 2009 compared to the 2010 offset by deferred financing costs amortized relating to the forward financing on the IRS Philadelphia Campus and Cira South Garage.
Recognized hedge activity
During 2009, we recorded a $1.1 million mark to market adjustment relating to two of our swaps that were applied to our September 2009 offering of $250.0 million 7.50% senior unsecured notes due 2015. The swaps no longer qualified for hedge accounting upon completion of this offering as the hedging relationship was terminated. Accordingly, the changes in the fair value of the swaps were reflected in our statement of operations until they were settled in cash in December 2009. We paid $5.1 million to terminate these swaps. We also recorded a net $0.1 million of income related to the write-off of AOCI and the ineffective portion of certain of our hedges.


54


Equity in income of real estate ventures
The increase in equity in income of real estate ventures of $1.2 millionventure from 2009 to 2010 is was mainly due to a distribution in 2010 of $0.6 million of sales proceeds that were held in escrow until resolution of certain contingencies arising from the sale of the property held by the Five Tower Bridge partnership. The remainder of the increase is the result of normal operating activities at the partnership level, and includes $0.1 million of preferred return pick-up from our ownership in a newly created real estate venture with Thomas Properties Group (Commerce Square).
Gain (loss) on early extinguishment of debt
During 2010, we repurchased (i) $68.1 million of our $345.0 million 3.875% Exchangeable Notes, (ii) $1.9 million of our $300.0 million 5.625% Guaranteed Notes due 2010 and (iii) $12.6 million of our $300.0 million 5.750% Guaranteed Notes due 2012 which resulted in a net loss on early extinguishment of debt of $2.2 million. The net loss was off-set by a gain from the write-off of the remaining premium on the PMEC note at the time of pay-off of $0.1 million resulting in an aggregate net loss on early extinguishment of debt of $2.1 million.
During 2009, we repurchased $154.1 million of our $345.0 million 3.875% Exchangeable Notes, $94.1 million of our $275.0 million 4.500% Guaranteed Notes due 2009, $77.0 million of our $300.0 million 5.625% Guaranteed Notes due 2010, $112.2 million of our $300.0 million 5.750% Guaranteed Notes due 2012 and $7.3 million of our $250.0 million 5.400% Guaranteed Notes due 2014 which resulted in a net gain on early extinguishment of debt of $23.2 million. The gain on early extinguishment of debt is inclusive of adjustments made to reflect our adoption of the new accounting standard for convertible debt instruments.
Discontinued Operations
During 2010, we sold one property in Richmond, VA, one property in Exton, PA, one property in King of Prussia, PA, one property in Austin, TX, and four properties in Marlton, NJ. These properties had total revenue of $6.4 million, operating expenses of $3.3 million, depreciation and amortization expenses of $2.0 million and gain on sale of $11.0 million.
The December 31, 2009 amounts are reclassified to include the operations of the properties sold during the twelve months period ended December 31, 2010, as well as all properties that were sold through the year ended December 31, 2009. Therefore, the discontinued operations amount for the twelve-months period ended December 31, 2009 includes total revenue of $20.6 million, operating expenses of $10.6 million and depreciation and amortization expense of $4.9 million. During the 2009, we also recognized a provision for impairment of $3.7 million on a property that was sold during the second quarter of 2009.

53


Net Income (Loss)
Net income decreased by $25.7 million from the twelve-month period ended December 31, 2009 as a result of the factors described above. Net income is significantly impacted by depreciation of operating properties and amortization of acquired intangibles. These non-cash charges do not directly affect our ability to pay dividends. Such charges can be expected to continue until lease intangibles are fully amortized. These intangibles are amortizing over the related lease terms or estimated duration of the tenant relationship.
Earnings (loss) per Common Share
Loss per share (basic and diluted) were $0.19was $(0.19) for the twelve-month period ended December 31, 2010 as compared to lossearnings per share of $0.00 for the twelve-month period ended December 31, 2009 as a result of the factors described above and an increase in the average number of common shares outstanding. The increase in the average number of common shares outstanding is primarily due to the commencement of the continuous equity Offering Program in March 2010 and the result of the $242.3 million public equity offering of 40,250,000 shares during the second quarter of 2009.

54


RESULTS OF OPERATIONS
Comparison of the Year Ended December 31, 2009 to the Year Ended December 31, 2008
The table below shows selected operating information for the “Same Store Property Portfolio” and the “Total Portfolio.” The Same Store Property Portfolio consists of 232 properties containing an aggregate of approximately 22.6 million net rentable square feet that we owned for the entire twelve-month periods ended December 31, 2009 and 2008. 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 twelve-month periods ended December 31, 2009 and 2008) by providing information for the properties which were acquired, under development (including lease-up assets) or placed into service and administrative/elimination information for the twelve-month periods ended December 31, 2009 and 2008 (in thousands).
The Total Portfolio net income presented in the table is equal to the net income of Brandywine Realty Trust and Brandywine Operating Partnership.

Total Revenue
Cash rents from the Total Portfolio increased by $2.5 million from 2008 to 2009, primarily reflecting:
1)An additional $5.8 million from four development/redevelopment properties that we completed and placed in service subsequent to 2008.
2)An additional $1.0 million of rental income due to increased occupancy at nine development/redevelopment properties in 2009 in comparison to 2008.
3)The increase was offset by the decrease of $4.9 million of rental income at our Same Store properties from 2008 to 2009 due to a decrease in occupancy of 380 basis points.
Straight-line rents at the Total Portfolio decreased by $6.8 million primarily due to free rent converting to cash rent during 2009.
Tenant reimbursements increased by $1.7 million from 2008 to 2009 primarily due to the increase in property operating expenses at our Same Store Portfolio. Tenant reimbursements increased by $1.6 million at our same store portfolio and the property operating expenses including real estate taxes at those properties increased by $2.9 million.
The decrease in termination fees of $1.2 million from 2008 to 2009 is mainly due to the recognition of a $3.1 million termination fee from one tenant during 2008 in comparison to a $1.2 million termination fee received from one tenant at one of redevelopment properties and a $0.6 million termination fee received from one tenant at one of our same store properties in 2009.
Third party management fees, labor reimbursement and leasing decreased by $3.3 million from 2008 to 2009 as a result of the termination of the management fee contract on March 31, 2008 that we entered into when we sold the 10 office properties located in Reading and Harrisburg, PA. As the contract was terminated early, approximately $0.8 million of unamortized deferred management fees were taken into income during 2008. The decrease also resulted from the termination of other third party management contracts totaling 4.3 million square feet subsequent to 2008.
Property Operating Expenses
Property operating expenses, including real estate taxes, at the Total Portfolio increased by $7.4 million due to increased repairs and maintenance expenses along with increased snow removal expenses during 2009 compared to 2008. We also incurred an additional $4.7 million of expenses from four properties that we completed and placed in service subsequent to 2008. These increases were offset by a decrease in the bad debt expense of $1.4 million from 2008 to 2009.
General & Administrative Expenses
General & administrative expenses decreased by $2.2 million from 2008 to 2009 mainly due to the severance costs of $2.4 million in 2008 that we did not have in 2009.
Depreciation and Amortization Expense
Depreciation and amortization increased by $6.5 million from 2008 to 2009, primarily due to $4.3 million of depreciation and amortization expense recorded on the four properties completed and placed in service subsequent to 2008. An additional $4.3 million of depreciation and amortization expense was recorded on portions of the nine development properties that were placed in service subsequent to 2008. The increase was offset by the decrease of $1.6 million at the Same Store Portfolio for asset write-offs related to early move-outs and fully amortized assets when comparing 2009 to 2008.
Interest Income/ Expense
Interest income increased by approximately $0.7 million, mainly due to the accretion of the $40.0 million non-interest bearing note receivable from the sale of the five Northern California properties in the fourth quarter of 2008. The note receivable was recorded at its present value on the date of sale of $37.1 million. During 2009, we recognized $1.6 million of interest income related to this note receivable and $0.2 million of interest income related to the $22.5 million note receivable from the sale of the two Trenton properties during the fourth quarter of 2009. During 2008, we recognized $0.4 million of interest income related to the note receivable from the sale of the five Northern California properties and $0.5 million of interest income received from a certificate of deposit investment.

57


The decrease in interest expense of $10.9 million is mainly due to the following:
decrease of $4.9 million resulting from the payoff at maturity of our $113.0 million private placement notes in December 2008.
decrease of $3.4 million resulting from a lower average Credit Facility balance at the end of 2009 and a lower weighted average interest rate on such borrowings in 2009 compared to December 31, 2008.
decrease of $6.9 million resulting from lower weighted average interest rates on our $183.0 million Bank Term Loan and our three Preferred Trust borrowings. Such borrowings have variable interest rates and a portion of such borrowings are swapped to fixed rate debt through our hedging program. This decrease is offset by an increase of $5.7 million paid under these hedges since the variable interest rates on such debt is lower than the swapped fixed rate on the hedges assigned to these borrowings.
decrease of $17.5 million resulting from our buybacks of unsecured notes in 2009. The details of the repurchases completed during the twelve months ended December 31, 2009 and 2008 are noted in theGain on early extinguishment of debtsection below. This decrease is offset by an increase of $5.1 million of interest on issuance of new notes.
The above explained net decrease of $21.9 million is offset by a decrease in capitalized interest of $7.9 million as a result of the decrease in the average balance, on open development and redevelopment projects, $0.3 million of interest expense related to our tax credit transactions, and an increase of $2.6 million from a higher outstanding mortgage notes payable balance as of December 31, 2009 compared to December 31, 2008.
Amortization of deferred financing costs increased by $0.4 million due to the acceleration of such expenses incurred in the debt repurchase activities of 2009.
Provision for impairment on land inventory
As part of our review of long-lived assets in accordance with the accounting standard for long-lived assets, during the quarter ending December 31, 2008, management determined that certain of the parcels in our land inventory considered at that time more likely to be sold had historical carrying values in excess of the current estimate of their fair value. Our impairment was recorded based on management’s estimate of the current fair value of the land inventory at that time.
Provision for Impairment on Real Estate
During the quarter ended March 31, 2009 impairment review, we determined that one of the properties tested for impairment under the held and used model had a historical cost greater than the probability weighted undiscounted cash flows. Accordingly, the recorded amount was reduced to an amount based on management’s estimate of the current fair value. During the nine months period ended September 30, 2008, we recorded a provision of $6.85 million for impairment relating to the sale of the five Northern California properties classifies as held for sale.
Where properties have been identified as having a potential for sale, additional judgments are required related to the determination as to the appropriate period over which the undiscounted cash flows should include the operating cash flows and the amount included as the estimated residual value. Management determines the amounts to be included based on a probability weighted cash flow. This requires significant judgment. In some cases, the results of whether an impairment is indicated are sensitive to changes in assumptions input into the estimates, including the hold period until expected sale.
Recognized hedge activity
During 2009, we recorded a $1.1 million mark to market adjustment relating to two of our swaps that were applied to our offering of $250.0 million 7.50% senior unsecured notes due 2015 completed in September 2009. The swaps no longer qualified for hedge accounting upon completion of this offering as the hedging relationship was terminated. Accordingly, the changes in the fair value of the swaps were reflected in our statement of operations until they were cash settled in December 2009. We paid $5.1 million to terminate these swaps. During the year, we also recorded a net $0.1 million of income related to the write-off of AOCI and the ineffective portion of certain of our hedges.

58


Equity in income of real estate ventures
The decrease in equity in income of real estate venture from 2008 to 2009 was mainly due to a payout of $3.2 million that we received for our interest in a real estate venture that was sold during the fourth quarter of 2008. The remainder of the decrease is primarily attributable to lower net income at the real estate venture properties.
Gain on early extinguishment of debt
During 2009, we repurchased $154.1 million of our $345.0 million 3.875% Exchangeable Notes, $94.1 million of our $275.0 million 4.500% Guaranteed Notes due 2009, $77.0 million of our $300.0 million 5.625% Guaranteed Notes due 2010, $112.2 million of our $300.0 million 5.750% Guaranteed Notes due 2012 and $7.3 million of our $250.0 million 5.400% Guaranteed Notes due 2014 which resulted in a net gain on early extinguishment of debt of $23.2 million. The gain on early extinguishment of debt is inclusive of adjustments made to reflect our adoption of the new accounting standard for convertible debt instruments.
During 2008, we repurchased $63.0 million of our $345.0 million 3.875% Guaranteed Exchangeable Notes, $78.3 million of our $275.0 million 4.500% Guaranteed Notes due 2009 and $24.5 million of our $300.0 million 5.625% Guaranteed Notes due 2010 which resulted in an $18.1 million gain that we reported for the early extinguishment of debt. The gain on extinguishment of debt has been retrospectively adjusted to reflect our adoption of the new accounting standard for convertible debt instruments.
Discontinued Operations
During the twelve month period ended December 31, 2009, we sold two properties in Exton, PA, one property in Moorestown, NJ, one property in Bethesda, MD, two properties in Trenton, NJ and a condominium unit and an undivided interest in an office building in Lawrenceville, NJ. These properties had total revenue of $13.5 million, operating expenses of $6.4 million, depreciation and amortization expenses of $2.2 million and gain on sale of $1.2 million. We determined that the sale of the two properties in Trenton, NJ should be accounted for using the Installment Sale Method. As a result, we deferred the portion of the gain which exceeded the calculated gain following the installment sale method. These amounts will decrease in proportion with the paydown of the principal balance on our note receivable from the buyer of the properties. The buyer is not obligated to make any principal payments over the next seven years. If they do make principal payments in advance, a portion of these amounts that are deferred will be recognized as a gain on sale in the period that we receive the cash for the principal payments. We also recorded a $3.7 million loss provision during the first quarter of 2009 in connection with the property in Bethesda, MD sold during the second quarter of 2009 which reduced our income from discontinued operations.
The December 31, 2008 amounts are reclassified to include the operations of the properties sold during the twelve months period ended December 31, 2009, as well as all properties that were sold through the year ended December 31, 2008. Therefore, the discontinued operations amount for the twelve months period ended December 31, 2008 includes total revenue of $60.8 million, operating expenses of $27.3 million, depreciation and amortization expense of $13.4 million, interest expense of $4.6 million and gains on sale of $28.5 million. We also recorded a $6.85 million loss provision in connection with the five Northern California properties classified as held for sale during the second quarter of 2008 which reduced our income from discontinued operations.
Net Income
Net income decreased by $30.4 million from the twelve-month period ended December 31, 2008 as a result of the factors described above. Net income is significantly impacted by depreciation of operating properties and amortization of acquired intangibles. These non-cash charges do not directly affect our ability to pay dividends. Such charges can be expected to continue until lease intangibles are fully amortized. These intangibles are amortizing over the related lease terms or estimated duration of the tenant relationship.
Earnings per Common Share
Loss per share (basic and diluted) were $0.00 for the twelve-month period ended December 31, 2009 as compared to earnings per share of $0.33 for the twelve-month period ended December 31, 2008 as a result of the factors described above and an increase in the average number of common shares outstanding. The increase in the average number of common shares outstanding is primarily the result of a $242.3 million public equity offering of 40,250,000 shares during the second quarter of 2009.

LIQUIDITY AND CAPITAL RESOURCES OF THE PARENT COMPANY
The Parent Company conducts its business through the Operating Partnership and its only material asset is its ownership of the partnership interests of the Operating Partnership. The Parent Company, other than acting as the sole general partner of the Operating Partnership, issues public equity from time to time and guarantees the debt obligations of the Operating Partnership. The Parent Company’s principal funding requirement is the payment of dividends on its common stockshares and preferred stock.shares. The Parent Company’s principal source of funding for its dividend payments is the distributions it receives from the Operating Partnership.
As of December 31, 2010,2011, the Parent Company owned a 93.1%98.1% interest in the Operating Partnership. The remaining 6.9%1.9% interest consists of common units of limited partnership interest owned by non-affiliated investors. As the sole general partner of the

55


Operating Partnership, the Parent Company has full and complete authority over the Operating Partnership’s day-to-day operations and management.
The Parent Company’s principal source of capital is from the distributions it receives from the Operating Partnership. The Parent Company believes that the Operating Partnership’s sources of working capital, particularly its cash flows from operations and borrowings available under its Credit Facility, are adequate for it to make its distribution paymentsdistributions to the Parent Company, which in turn will enable the Parent Company to make dividend payments to its stockholders.shareholders.
The Parent Company receives proceeds from equity issuances from time to time, but is required by the Operating Partnership’s partnership agreement to contributeand contributes the proceeds from its equity issuances to the Operating Partnership in exchange for partnership units 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 its shares. The Parent Company regularly analyzes which source of capital is most advantageous to it at any particular point in time. In March 2010, the Parent Company commenced a continuous equity Offering Program, under which it may sell up to an aggregate amount of 15,000,000 common shares until March 10, 2013 in amounts and at times to be determined by the Parent Company. Actual sales will depend on a variety of factors to be determined by the Parent Company, including market conditions, the trading price of its common shares and determinations by the Parent Company of the appropriate sources of funding. In conjunction with the Offering Program, the Parent Company engaged sales agents who received compensation, in aggregate, of up to 2% of the gross sales price per share sold duringshare. During the the twelve months ended December 31, 2010. Through December 31, 2010,2011, the Parent Company sold 5,742,268679,285 shares under this program at an average sales price of $12.54$12.18 per share resulting in net proceeds of $70.8 million.$8.0 million. The Parent Company contributed the net proceeds from the sales to the Operating Partnership.Partnership, which the Operating Partnership in turn used to reduce borrowings under the Credit Facility and for general corporate purposes. From its inception through December 31, 2011, the Parent Company had sold 6,421,553 shares under this program, leaving 8,578,447 shares available for sale.
On December 2, 2010,13, 2011, the Parent Company declared a distribution of $0.15$0.15 per common share, totaling $20.3$21.5 million, which it paid on January 20, 201119, 2012 to its shareholders of record as of January 6, 2011.5, 2012. In addition, the Parent Company declared distributions on its Series C Preferred Shares and Series D Preferred Shares to holders of record as of December 30, 2010.2011. These shares are entitled to a preferential return of 7.50% and 7.375%, respectively. Distributions paid on January 18, 201117, 2012 to holders of Series C Preferred Shares and Series D Preferred Shares totaled $0.9$0.9 million and $1.1$1.1 million, respectively.
The Parent Company also maintains a share repurchase program under which its Board of Trustees has authorized the Parent Company to repurchase its common shares from time to time. As of December 31, 2010,2011, there were approximately 0.5 million shares remaining to be repurchased under this program. The Parent Company’s Board of Trustees has not limited the duration of the program; however, it may be terminated at any time.
Together with the Operating Partnership, the Parent Company maintains a shelf registration statement that has registered common shares, preferred shares, depositary shares and warrants and unsecured debt securities. Subject to the Company’s ongoing compliance with securities laws, and if warranted by market conditions, the Company may offer and sell equity and debt securities from time to time under the shelf registration statement.
The Parent Company alsounconditionally guarantees the Operating Partnership’s secured and unsecured debt obligations which as of December 31, 2010,2011 amounted to $712.2$1,888.1 million and $1,722.3 million, respectively.. If the Operating Partnership were to failfails to comply with its debt requirements, the Parent Company wouldwill be required to fulfill the Operating Partnership’sPartnership's commitments under such guarantees. As of December 31, 2010,2011, the Operating Partnership wasis in compliance with all of its debt covenants.covenant and requirement obligations.
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. The Parent Company has historically satisfied this requirement.
Overall, the liquidity of the Parent Company is dependent on the Operating Partnership’s ability to make distributions to the Parent Company. However, there can be no assurance that the Operating Partnership’s sources of capital will continue to be available to meet its working capital needs including its ability to make distribution paymentsdistributions to the Parent Company. In cases where the Operating Partnership is faced with working capital problems or would need to raise capital to fund acquisitions and developments, the Parent Company will have to consider alternative sources to increase liquidity, including, among other things, equity issuances through its existing Offering Program, use ofadvances under its available line of creditCredit Facility and potential salesales of properties.

LIQUIDITY AND CAPITAL RESOURCES OF THE OPERATING PARTNERSHIP
General
The Operating Partnership’s principal liquidity needs for the next twelve months are as follows:

56



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 currentpotential development and redevelopment costs, and
fund distributions to the Parent Company.
The Operating Partnership believes that with the uncertain economic conditions, it is likely that vacancy rates may continue to increase, effective rental rates on new and renewed leases may continue to decrease and tenant installation costs, including concessions, may continue to increase in most or all of its markets in 20112012 and possibly beyond. As a result, the Operating Partnership’s revenue from the overall reduced demand for office space, and its cash flow could be insufficient to cover increased tenant installation costs over the short-term. If this situation were to occur, the Operating Partnership expects that it would finance cash deficits through borrowings under our Credit Facility and other debt and equity financings.
The Operating Partnership believes that its liquidity needs will be satisfied through cash flows generated by operations, financing activities and selective property sales. Rental revenue, expense recoveries from tenants, and other income from operations are its principal sources of cash used to pay operating expenses, debt service, recurring capital expenditures and the minimum distributions required to maintain its REIT qualification. The Operating Partnership seeks to increase cash flows from its properties by maintaining quality standards for its properties that promote high occupancy rates and permit increases in rental rates while reducing tenant turnover and controlling operating expenses. The Operating Partnership’s revenue also includes third-party fees generated by its property management, leasing, development, and construction businesses. The Operating Partnership believes that its revenue, together with proceeds from property sales and debt financings, will continue to provide funds for its short-term liquidity needs. However, material changes in its operating or financing activities may adversely affect its net cash flows. Such changes, in turn, would adversely affect its ability to fund distributions to the Parent Company, debt service payments and tenant improvements. In addition, a material adverse change in its cash provided by operations would affect the financial performance covenants under itsthe Credit Facility, unsecured term loan and unsecured notes.
Financial markets have experienced unusual volatility and uncertainty. The Operating Partnership’s ability to fund future development projects, as well as its ability to repay or refinance debt maturities could be adversely affected by its inability to secure financing at reasonable terms beyond those already completed. It is possible, in these unusual and uncertain times that one or more lenders in its Credit Facility could fail to fund a borrowing request. Such an event could adversely affect its ability to access funds from its Credit Facility when needed.
The Operating Partnership’sPartnership's liquidity management remains a priority. The Operating Partnership is proactively pursuingregularly pursues new financing opportunities to ensure an appropriate balance sheet position. As a result of these dedicated efforts, the Operating Partnership is comfortable with its ability to meet future debt maturities and development or property acquisition funding needs. The Operating Partnership believes that its current balance sheet is in an adequate position at the date of this filing, despite the volatility in the credit and financial markets. The following are the Operating Partnership’s significant activities during 2010 affecting its liquidity management:
From the inception of the Parent Company’s continuous equity Offering Program in March 2010 through On December 31, 2010,15, 2011, the Parent Company hadand the Operating Partnership entered into binding agreements for lender commitments related a new $600.0 million four -year unsecured credit facility and three unsecured term loans in the same aggregate amount of $600.0 million , consisting of a $150.0 million three-year loan, a $250.0 million four-year loan and a $200.0 million seven-year loan. The Parent Company and the Operating Partnership closed on the new credit facility and term loans (referred to earlier in this Form 10-K as our "New Credit Facility" and "New Term Loans," respectively) on February 1, 2012 and used the proceeds from the initial advances under the New Term Loans to repay all balances outstanding under, and concurrently terminate, the Prior Credit Facility and Prior Term Loan. The New Credit Facility has terms that are generally comparable to those under the Prior Credit Facility.
On April 5, 2011, the Operating Partnership closed a registered offering of $325.0 million in aggregate principal amount of its 4.95% senior unsecured notes due 2018. The notes were priced at 98.907% of their face amount with an effective interest rate of 5.137%. The net proceeds, which amounted to $318.9 million after deducting underwriting discounts and offering expenses, were used to repay indebtedness under the Credit Facility and for general corporate purposes.
During 2011, the Parent Company contributed $70.8$8.0 million in net proceeds from the sale of 5,742,268679,285 of its common shares under the Offering Program to the Operating Partnership in exchange for the issuance of 5,742,268679,285 common partnership units to the Parent Company. The Operating Partnership used the net proceeds contributed by the Parent Company to reduce borrowings under the Credit Facility and for general corporate purposes.
In June 2010, the Operating Partnership through one of its wholly owned TRS entities, received a $27.4 million contribution under the historic tax credit transaction entered into in 2008 with US Bancorp.

On August 5, 2010, the Operating Partnership issued 7,111,112 units of its newly-established Class F (2010) Units in connection with the acquisition of Three Logan Square. The Class F (2010) Units do not accrue a dividend and are not entitled to income or loss allocations prior to the first anniversary of the closing. They are also not convertible into the Parent Company’s common shares for that period. For purposes of computing the total purchase price of Three Logan Square, the Class F (2010) Units were valued based on the closing market price of the Parent Company’s common shares on the acquisition date of $11.54 less the annual dividend rate per share of $0.60 to reflect that these units do not begin to accrue a dividend prior to the first anniversary of their issuance.
On August 26, 2010, the Operating Partnership received $254.0 million of gross proceeds from a $256.5 million forward financing commitment that the Operating Partnership obtained on June 29, 2009. The Operating Partnership paid a $17.7 million commitment fee in connection with this commitment. The loan proceeds, together with the commitment fee, had been escrowed with an institutional trustee pending the completion of the IRS Philadelphia Campus and the Cira South Garage as well as the commencement of the leases at these facilities. The financing consists of two separate loans: $209.7 million secured by the IRS Philadelphia Campus and $46.8 million secured by the Cira South Garage. The lender held back $2.5 million of the loan proceeds pending the completion of certain conditions related to the IRS Philadelphia Campus and the Cira South Garage. As of December 31, 2010, the Operating Partnership has received $2.1 million of the total amount held back. The loans are non-recourse and are secured by the IRS Philadelphia Campus and the Cira South Garage, respectively. The loans bear interest at 5.93% per annum with interest only through September 10, 2010 and thereafter require principal and interest monthly payments through its maturity in September 2030. The Operating Partnership used the loan proceeds to reduce borrowings under its Credit Facility and for general corporate purposes.
The Operating Partnership uses multiple financing sources to fund its long-term capital needs. It uses its Credit Facility for general business purposes, including the acquisition, development and redevelopment of properties and the repayment of other debt. It

will also consider otherobtaining debt secured by properties within its portfolio as necessary, where it may be in its best interest to obtain a secured mortgage.
The Operating Partnership’s ability to incur additional debt is dependent upon a number of factors, including its credit ratings, the value of its unencumbered assets, its degree of leverage and borrowing restrictions imposed by its current lenders. If more than one rating agency were to downgrade its credit rating, its access to capital in the unsecured debt market would be more limited and the interest rate under its existing Credit Facility and the term loan would increase.
The ability of the Parent Company and the Operating Partnership’s abilityPartnership to sell its limited partnership and preferred unitstheir equity securities is dependent on, among other things, general market conditions for REITs, market perceptions about the Company and the current trading price of the Parent Company’s shares. The Parent Company contributes the proceeds it receives from its equity issuances to the Operating Partnership in exchange for partnership units of the Operating Partnership in accordance with the Operating Partnership’s partnership agreement. The Operating Partnership uses the net proceeds from the sales contributed by the Parent Company to reduce borrowings under the Credit Facility and for general corporate purposes. The Operating Partnership, from time to time, also issues its own partnership units as consideration for property acquisitions and developments as shown in one of the Operating Partnership’s activities during 2010 abovedevelopments.
The Operating Partnership will also consider sales of selected Properties as another source of managing its liquidity. Asset sales during 20092010 and through 20102011 have been a source of cash. During 2010, it2011, we sold 8four properties containing 0.50.4 million in net rentable square feet for net cash proceeds of $50.1$34.8 million. During 2011, the Company also contributed three properties, containing 0.6 million net rentable square feet, to an unconsolidated joint venture and received, in addition to a 50% interest in the venture, net cash proceeds of $120.1 million. Since mid-2007, theThe Operating Partnership has used proceeds from asset sales to repay existing indebtedness, provide capital for its development activities and strengthen its financial condition. There is no guarantee that it will be able to raise similar or even lesser amounts of capital from future asset sales.
Cash Flows
The following summary discussion of the Operating Partnership’s cash flows is based on the consolidated statement of cash flows and is not meant to be an all-inclusive discussion of the changes in our cash flows for the periods presented.
As of December 31, 20102011 and 2009,2010, the Operating Partnership maintained cash and cash equivalents of $16.6$0.4 million and $1.6$16.6 million, respectively.

The Operating Partnership’s principal source of cash flows is from the operation of its properties. The Operating Partnership does not restate its cash flow for discontinued operations.
The net decrease of $35.3$6.1 million in cash flows from operating activities of the Operating Partnership during the year ended December 31, 20102011 compared to the year ended December 31, 20092010 is primarily the result of the following:

a decrease in average occupancy from 89.3%86.7% during the year ended December 31, 20092010 to 87.6%85.3% during the year ended December 31, 2010;2011;
a decrease in the number of operating properties due to dispositions. We sold a total of eightfour office properties and contributed three office properties to an unconsolidated real estate venture during the year ended December 31, 2010;2011; and
timing of cash receipts from our tenants and cash expenditures in the normal course of operations.
These decreases were offset by the following transactions:
acquisition of Three Logan Square and the completion and placement in service of the IRS Philadelphia Campus and Cira South Garage during the third quarter of 2010, acquisition of Overlook I and II during the first quarter of 2011, the placement in service of the Juniper Street Parking Garage during the second quarter of 2011, and the acquisition of 3020 Market Street during the third quarter of 2011; and
receipt of $27.4 million from the historic tax credit transaction in June 2010 and recognition of $12.0 million of the total contributions received as income during the third quarter of 2011.

The 2011 total net proceeds from sales of properties included $120.1 million from the sale of three properties to a newly formed unconsolidated real estate venture (see Note 3 to the following:consolidated financial statements for additional information);
decreased capital expenditures for tenant and building improvements and leasing commissions by $34.8 million during the year ended December 31, 2011 compared to the year ended December 31, 2010.

The Operating Partnership uses Credit Facility borrowings for general business purposes, including the acquisition, development and redevelopment of properties and the repayment of other debt. It has the option to increase the maximum borrowings under its Credit Facility to $800.0$800.0 million subject to the absence of any defaults and its ability to obtain additional commitments from its existing or new lenders. For a discussion of the Company's New Credit Facility and New Unsecured Terms Loans, on which closing occurred on February 1, 2012, see "Item 1. Business - 2011 Transactions."
The interest rates incurred under our revolvingthe Credit Facility and our unsecured term loanloans are subject to modification depending on our rating status with qualified agencies.
As of December 31, 2010,2011, the Operating Partnership had $183.0$275.5 million of borrowings and $11.2$2.5 million of letters of credit outstanding under the then existing Credit Facility, leaving $405.8$322.0 million of unused availability.

The Credit Facility contains financial and non-financial covenants, including covenants that relate to the Operating Partnership’s incurrence of additional debt; the granting of liens; consummation of mergers and consolidations; the disposition of assets and interests in subsidiaries; the making of loans and investments; and the payment of dividends. The restriction on dividends permits the Operating Partnership to make distributions to the Parent Company based on the greater of (i) an amount required for the Parent Company to retain its qualification as a REIT and (ii) 95% of the Operating Partnership’s funds from operations. The Credit Facility also contains financial covenants that require the Operating Partnership to maintain an interest coverage ratio, a fixed charge coverage ratio, an unsecured debt ratio and an unencumbered cash flow ratio above certain specified minimum levels; to maintain net worth above an amount determined on a specified formula; and to maintain a leverage ratio and a secured debt ratio below certain maximum levels. Another financial covenant limits the ratio of unsecured debt to unencumbered properties. The Operating Partnership continuously monitors its compliance with the covenants. Certain of the covenants restrict the Operating Partnership’s ability to obtain alternative sources of capital. The Operating Partnership was in compliance with all covenants as of December 31, 2010.2011.
The indenture under which the Operating Partnership issued its unsecured Notes contains financial covenants, including (1) a leverage ratio not to exceed 60%, (2) a secured debt leverage ratio not to exceed 40%, (3) a debt service coverage ratio of greater than 1.5 to 1.0 and (4) an unencumbered asset value of not less than 150% of unsecured debt. The Operating Partnership was in compliance with all covenants as of December 31, 2010.2011.
The Operating Partnership has mortgage loans that are collateralized by certain of its Properties. Payments on mortgage loans are generally due in monthly installments of principal and interest, or interest only. The Operating Partnership intends to refinance or repay its mortgage loans as they mature through the use of proceeds from selective Property sales and secured or unsecured borrowings. However, in the current and future economic environment one or more of these sources may not be available on attractive terms or at all.

65


The Parent Company’s charter documents do not limit the amount or form of indebtedness that the Operating Partnership may incur, and its policies on debt incurrence are solely within the discretion of the Parent Company’s Board of Trustees, subject to financial covenants in the Credit Facility, indenture and other credit agreements.
As of December 31, 2010,2011, the Operating Partnership had guaranteed repayment of approximately $0.7$0.7 million of loans on behalf of one Real Estate Venture. See Item 2. Properties — Real Estate Ventures. The Operating Partnership also provides customary environmental indemnities and completion guarantees in connection with construction and permanent financing both for its own account and on behalf of certain of the Real Estate Ventures.
Equity
On December 2, 2010,13, 2011, the Operating Partnership declared a distribution of $0.15$0.15 per Class A common unit, totaling $20.3$21.5 million, which was paid on January 20, 201119, 2012 to unitholders of record as of January 6, 2011.5, 2012.
On December 2, 2010,13, 2011, the Operating Partnership declared distributions on its Series D Preferred Mirror Units and Series E Preferred Mirror Units to holders of record as of December 30, 2010.2011. These units are entitled to a preferential return of 7.50% and 7.375%, respectively. Distributions paid on January 18, 201117, 2012 to holders of Series D Preferred Mirror Units and Series E Preferred Mirror Units totaled $0.9$0.9 million and $0.1$1.1 million, respectively.
On December 23, 2011, the Parent Company issued 7,111,112 of its common shares in exchange for an equal number of Class F (2010) Units of the Operating Partnership. The Class F (2010) Units were issued in August 2010 as part of our acquisition of an office property and were subject to redemption at the option of the holder after the first anniversary of the issuance. The Operating Partnership had the option to satisfy the redemption either for an amount, per unit, of cash equal to the market price of one of the Parent Company's common shares (based on the five-day trading average ending on the date of the exchange) or for one of the Parent Company's common shares for each unit redeemed. On December 23, 2011, the Operating Partnership satisfied in full BAT Partners, L.P.'s tender for redemption of all 7,111,112 of the Class F (2010) Units through the issuance of 7,111,112 Parent Company's common shares.
From the inception of the Offering Program in March 2010 through December 31, 2010,2011, the Parent Company contributed net proceeds of $70.8$8.0 million from the sale of 5,742,268679,285 shares to the Operating Partnership in exchange for the issuance of 5,742,268679,285 common partnership units to the Parent Company. The Operating Partnership used the net proceeds from the sales to reduce borrowings under the Credit Facility and for general corporate purposes.
On August 5, 2010, the Operating Partnership issued 7,111,112 Class F (2010) units as part of its consideration for the acquisition of Three Logan Square. The Class F (2010) units were valued based on the closing market price of the Parent Company’s common shares on the acquisition date of $11.54 less the annual dividend rate per share of $0.60 to reflect that these units do not begin to accrue a dividend prior to the first anniversary of their issuance. The Class F (2010) units are subject to redemption at the option of holder after August 5, 2011. The Operating Partnership may, at its option, satisfy the redemption either for an amount, per unit, of cash equal to the market price of one Parent Company common share (based on the five-day trading average ending on the date of the redemption) or for one Parent Company common share. The Class F (2010) units do not begin to accrue dividends and are not entitled to income or loss allocations prior to August 5, 2011. Thereafter, the Class F (2010) units will receive the same dividend that the Parent Company pays on its common shares.
Thepurposes.The Parent Company did not purchase any shares during the year ended December 31, 20102011 and accordingly, during the year ended December 31, 2010,2011, the Operating Partnership did not repurchase any units in connection with the Parent Company’s share repurchase program.
Together with the Operating Partnership, the Parent Company maintains a shelf registration statement that has registered common

61


shares, preferred shares, depositary shares and warrants and unsecured debt securities. Subject to the Company’s ongoing compliance with securities laws, if warranted by market conditions, the Company may offer and sell equity and debt securities from time to time under the shelf registration statement.

66


Short- and Long-Term Liquidity
The Operating Partnership believes that its cash flow from operations is adequate to fund its short-term liquidity requirements, excluding principal payments under its debt obligations. Cash flow from operations is generated primarily from rental revenues and operating expense reimbursements from tenants and management services income from providing services to third parties. The Operating Partnership intends to use these funds to meet short-term liquidity needs, which are to fund operating expenses, recurring capital expenditures, tenant allowances, leasing commissions, interest expense and the minimum distributions to the Parent Company required to maintain the Parent Company’s REIT qualification under the Internal Revenue Code. The Operating Partnership expects to meet short-term scheduled debt maturities through borrowings under the Credit Facility and proceeds from asset dispositions. As of December 31, 2010,2011, the Operating Partnership has $1,722.3$1,888.1 million of unsecured debt and $712.2$512.4 million of mortgage debt of which $425.8$464.5 million and $128.5$12.4 million, respectively, are scheduled to mature through December 2011.2012. The Operating Partnership extended the maturity date of the $183.0$183.0 million Term Loan from October 18, 2010June 29, 2011 to June 29, 2011. The2012. On December 15, 2011, the Parent Company and the Operating Partnership may extend the maturity dates of theentered into binding agreements for lender commitments related to a New Credit Facility and the term loanNew Term Loan. The Company closed on the New Credit Facility and Term Loans on February 1, 2012 and used the initial advances under the New Term Loans to June 29, 2012.repay all balances outstanding under, and concurrently terminate, its prior Credit Facility and the prior Term Loan. For the remaining debt maturities, the Operating Partnership expects to have sufficient capacity under its New Credit Facility but it will also evaluate other listed sources to fund these maturities.
The Operating Partnership expects to meet its long-term liquidity requirements, such as for property acquisitions, development, investments in real estate ventures, scheduled debt maturities, major renovations, expansions and other significant capital improvements, through cash from operations, borrowings under the Credit Facility, additional secured and unsecured indebtedness, the issuance of equity securities, contributions from joint venture investors and proceeds from asset dispositions.
Many commercial real estate lenders have substantially tightenedstricter underwriting standards or have withdrawn from the lending marketplace. Also, spreads in the investment grade bond market remain wider than historic spreads. These circumstances haveCurrent global economic sluggishness has impacted liquidity in the debt markets, making financing terms less attractive, and in certain cases have resulted in the unavailability of certain types of debt financing. As a result, the Operating Partnership expects debt financings will be more difficult to obtain and that borrowing costs on new and refinanced debt willcould be more expensive. Moreover, the volatility in the financial markets, in general, will make it more difficult or costly, for it to raise capital through the issuance of common stock, preferred stock or other equity instruments or through public issuances of debt securities from its shelf registration statement as it has been able to do in the past. Such conditions would also limit its ability to raise capital through asset dispositions at attractive prices or at all.
Off-Balance Sheet Arrangements
We are not dependent on any off-balance sheet financing arrangements for liquidity. Our off-balance sheet arrangements are discussed in Note 4 to the financial statements, “Investment in Unconsolidated Real Estate Ventures”. Additional information about the debt of our unconsolidated Real Estate Ventures is included in “Item 2 —2. Properties”.
Inflation
A majority of the Operating Partnership’s leases provide for tenant reimbursement of real estate taxes and operating expenses either on a triple net basis or over a base amount. In addition, many of its office leases provide for fixed base rent increases. The Operating Partnership believes that inflationary increases in expenses will be partially offset by expense reimbursement and contractual rent increases.

The Operating Partnership hasobtained ground tenancy rights under a long term ground lease agreement through its acquisition ofwhen it acquired Three Logan Square on August 5, 2010. The annual rental payment under this ground lease is ten dollars through August 2022, which is when the initial term of the ground lease will end. After the initial term, the Operating Partnership has the optionvarious options to renew the lease until 2091. The Operating Partnership also hasobtained the option to purchase the land at fair market value after providing a written notice to the owner. The annual rental payment after 2022 will be adjusted at the lower of $3.0 million or the prevailing market rent at that time until 2030. Subsequent to 2030, the annual rental payment will be adjusted at the lower of $4.0 million or the prevailing market rent at that time until 2042 and at fair market value until 2091. The Operating Partnership believes that based on conditions as of the date the lease was assigned (August 5, 2010), the lease will reset to market after the initial term. Using the estimated fair market rent as of the date of the acquisition over the extended term of the ground lease (assuming the purchase option is not exercised), the future payments will aggregate to $27.4 million. The Operating Partnership has not included the amounts in the table above since such amounts are not fixed and determinable. The Operating Partnership also acquired ground tenancy rights under a long term ground lease agreement related to its acquisition of an office building in Philadelphia, Pennsylvania on August 12, 2011. The annual rental payments under this ground lease are equal to a percentage of the NOI generated by the property. The Company has not included the amounts in the table above since such amounts are not fixed or determinable.
As part of the Operating Partnership’sPartnership's September 2004 acquisition of a portfolio of properties from Thethe Rubenstein Company (which the Operating Partnership refers to as the “TRC acquisition”), the Operating Partnership acquired its interest in Two Logan Square, a 706,288708,844 square foot office building in Philadelphia, primarily through its ownership of a second and third mortgage secured by this property. This property is consolidated as the borrower is a variable interest entity and the Operating Partnership, through its ownership of the second and third mortgages, is the primary beneficiary. It currently does not expect to take title to Two Logan Square until, at the earliest, September 2019. If the Operating Partnership takes fee title to Two Logan Square upon a foreclosure of its mortgage, the Operating Partnership has agreed to pay an unaffiliated third party that holds a residual interest in the fee owner of this property an amount equal to $2.9 million. On the TRC acquisition date, the Operating Partnership recorded a liability of $0.7 million and this amount will accrete up to $2.9 million through September 2019. As of December 31, 2010,2011, the Operating Partnership has a balance of $1.2$1.3 million for this liability inon its consolidated balance sheet.

The Operating Partnership has been audited by the Internal Revenue Service (the “IRS”) for its 2004 tax year. The audit concernsconcerned the tax treatment of the TRC acquisition in September 2004 in which the Operating Partnership acquired a portfolio of properties through the acquisition of a limited partnership. On December 17, 2010, the Operating Partnership received notice that the IRS proposed an adjustment to the allocation of recourse liabilities allocated to the contributor of the properties. The Operating Partnership intends to appealhas appealed the proposed adjustment. The proposed adjustment, if upheld, would not result in a material tax liability for the Operating Partnership. However, an adjustment could raise a question as to whether a contributor of partnership interests in the 2004 transaction could assert a claim against the Operating Partnership under the tax protection agreement entered into as part of the transaction.

68


As part of the Operating Partnership’sPartnership's 2006 Prentiss merger, the 2004 TRC acquisition and the TRC acquisition in 2004,several of its other transactions, it agreed not to sell certain of the properties it acquired in transactions that would trigger taxable income to the former owners. In the case of the TRC acquisition, the Operating Partnership agreed not to sell acquired properties for periods up to 15 years from the date of the TRC acquisition as follows at December 31, 2010:2011: One Rodney Square and 130/150/170 Radnor Financial Center (January, 2015); and One Logan Square, Two Logan Square and Radnor Corporate Center (January, 2020). In the Prentiss acquisition, the Operating Partnership assumed the obligation of Prentiss not to sell Concord Airport Plaza before March, 2018. The Operating Partnership’sPartnership's agreements generally provide that we may dispose of the subject properties only in transactions that qualify as tax-free exchanges under Section 1031 of the Internal Revenue Code or in other tax deferred transactions. If the Operating Partnership was to sell a restricted property before expiration of the restricted period in a non-exempt transaction, it would be required to make significant payments to the parties who sold the applicable property to the Operating Partnership for tax liabilities triggered to them.
As part of the Operating Partnership’s acquisition of properties from time to time in tax-deferred transactions, it has agreed to provide certain of the prior owners of the acquired properties with the right to guarantee its indebtedness. If the Operating Partnership waswere to seek to repay the indebtedness guaranteed by the prior owner before the expiration of the applicable agreement, it willwould be required to provide the prior owner an opportunity to guarantee a qualifying replacement debt. These debt maintenance agreements may limit itsthe Operating Partnership's ability to refinance indebtedness on terms that will be favorable to the Operating Partnership.
In connection with the development of the IRS Philadelphia Campus and the Cira South Garage, during 2008, the Operating Partnership entered into a historic tax credit and new markets tax credit arrangement, respectively. The Operating Partnership is required to be in compliance with various laws, regulations and contractual provisions that apply to its historic and new market tax credit arrangements. Non-compliance with applicable requirements could result in projected tax benefits not being realized and therefore, require a refund to USB or reduction of investor capital contributions, which are reported as deferred income in the Operating Partnership’s consolidated balance sheet, until such time as its obligation to deliver tax benefits is relieved. The remaining compliance periods for its tax credit arrangements runs through 2015. The Operating Partnership does not anticipate that any material refunds or reductions of investor capital contributions will be required in connection with these arrangements.
The Operating Partnership invests in properties and regularly incurs capital expenditures in the ordinary course of its business to maintain the properties. The Operating Partnership believes that such expenditures enhance its competitiveness. The Operating Partnership also enters into construction, utility and service contracts in the ordinary course of its business which may extend beyond one year. These contracts typically provide for cancellation with insignificant or no cancellation penalties.
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.
The Operating Partnership’s financial instruments consist of both fixed and variable rate debt. As of December 31, 2010,2011, its consolidated debt consisted of $652.2$512.4 million in fixed rate mortgages, $60.0 million ofno variable rate mortgages, $183.0$275.5 million in borrowings under its Credit Facility, $183.0$37.5 million borrowings in an unsecured term loan and $1,356.3$1,575.1 million in unsecured notes (before reduction of discounts) of which $1,277.7$1,549.3 million are fixed rate or variable swapped to fixed rate borrowings and $78.6$25.8 million are variable rate borrowings. 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 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.
As of December 31, 2010,2011 based on prevailing interest rates and credit spreads, the fair value of the Operating Partnership’s unsecured notes was $1.3$1.6 billion. For sensitivity purposes, a 100 basis point change in the discount rate equates to a change in the

64


total fair value of its debt, including the Notes, of approximately $12.7$14.9 million at December 31, 2010.2011.
From time to time or as the need arises, the Operating Partnership uses derivative instruments to manage interest rate risk exposures and not for speculative purposes. All ofDuring December 2011, the Operating Partnership’s interest rate swap agreements maturedPartnership executed hedging transactions that fix the rates on October 18, 2010.the New Term Loans and on two of its existing unsecured senior notes. All hedges commenced on February 1, 2012 (see Note 9 for additional information).
The total carrying value of the Operating Partnership’s variable rate debt (including variable swapped to fixed) was approximately $444.6$391.6 million and $353.6$444.6 million at December 31, 2011 and December 31, 2010 and December 31, 2009,, respectively. The total fair value of the Operating Partnership’s debt was approximately $432.6$380.8 million and $341.2$432.6 million at December 31, 2011 and December 31, 2010 and December 31, 2009,, respectively. For sensitivity purposes, a 100 basis point change in the discount rate equates to a change in the total fair value of its debt of approximately $4.4$3.4 million at December 31, 2010,2011, and a 100 basis point change in the discount rate equates to a change in the total fair value of its debt of approximately $1.5$4.4 million at December 31, 2009.2010.

69


If market rates of interest were to increase by 1%, the fair value of the Operating Partnership’s outstanding fixed-rate mortgage debt would decrease by approximately $33.4$28.9 million. If market rates of interest were to decrease by 1%, the fair value of its outstanding fixed-rate mortgage debt would increase by approximately $36.5$31.8 million.
At December 31, 2010,2011, the Operating Partnership’s outstanding variable rate debt (including variable swapped to fixed) based on LIBOR totaled approximately $444.6 million.$391.6 million. At December 31, 2010,2011, the interest rate on its variable rate debt was approximately 1.1%. If market interest rates on its variable rate debt change by 100 basis points, total interest expense would change by approximately $1.1$0.8 million for the year ended December 31, 2010.2011.
These amounts were determined solely by considering the impact of hypothetical interest rates on the Operating Partnership’s financial instruments. Due to the uncertainty of specific actions the Operating Partnership may undertake to minimize possible effects of market interest rate increases, this analysis assumes no changes in its applicable financial instruments or structure.
Funds from Operations (FFO)
Pursuant to the 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, real estate related depreciation, amortization, impairment charges, investment write-downs, and after similar adjustments for unconsolidated real estate ventures. FFO is a non-GAAP financial measure. The Operating Partnership believes that the use of FFO combined with the required U.S. GAAP presentations, has been beneficial in improving the understanding of operating results of REITs among the investing public and making comparisons of REITs' operating results more meaningful. The Operating Partnership considers 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. The Operating Partnership's 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.
The Operating Partnership considers net income, as defined by U.S. GAAP, to be the most comparable earnings measure to FFO. While FFO and FFO per unit are relevant and widely used measures of operating performance of REITs, FFO does not represent cash flow from operations or net income as defined by U.S. GAAP and should not be considered as alternatives to those measures in evaluating the company's liquidity or operating performance. The Operating Partnership believes that to further understand our performance, FFO should be compared with its 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 years ended December 31, 2011 and 2010:

Report of Independent Registered Public Accounting Firm
To the Board of Trustees and Shareholders of Brandywine Realty Trust:
In our opinion, the consolidated financial statements listed in the index appearing under Item 15(a)(1) present fairly, in all material respects, the financial position of Brandywine Realty Trust and its subsidiaries (the “Company”) at December 31, 20102011 and 2009,2010, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 20102011 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedules listed in the index appearing under Item 15(a)(2) present fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010,2011, based on criteria established inInternal Control — Integrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements and financial statement schedules, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements, on the financial statement schedules and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
As described in Management’s Report on Internal Control Over Financial Reporting, management has excluded Three Logan Square from its assessment of internal control over financial reporting as of December 31, 2010 because it was acquired by the Company in a purchase business combination during 2010. We have also excluded Three Logan Square from our audit of internal control over financial reporting. Three Logan Square is a wholly-owned property whose total assets and total revenue represent 2.7% and 1.3%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2010.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Reclassifications
Certain amounts have been reclassified in prior years to conform to the current year presentation with no effect to previously reported net income and equity. The reclassifications are primarily due to the treatment of sold properties as discontinued operations on the statement of operations for all periods presented. Effective December 31, 2010, the Company is reflecting all deferred income, gains, and rents that will be amortized to revenue as a separate line item in the consolidated balance sheets and all liabilities that are expected to cash settle including security deposits as other liabilities to conform to the current year presentation. The change in the groupings of the liabilities combined deferred rents and income of $50.0 million and $47.4 million, respectively, as of December 31, 2009, to the new line item “Deferred income, gains and rents” in the consolidated balance sheets. The change in the groupings of the liabilities also increased other liabilities in the consolidated balance sheets by $2.6 million as of December 31, 2009.
In addition, the Company changed $5.6 million from leasing costs to capital expenditures in the investing section of the statement of cash flows for the year ended December 31, 2009. This change had no effect on the subtotals within the consolidated statement of cash flows.

F - 15


Principles of Consolidation
When the Company obtains an economic interest in an entity, the Company evaluates the entity to determine if the entity is deemed a variable interest entity (“VIE”), and if the Company is deemed to be the primary beneficiary, in accordance with the accounting standard for the consolidation of variable interest entities. The accounting standard for the consolidation of VIEs requires the Company to qualitatively assess if the Company was the primary beneficiary of the VIEs based on whether the Company had both (i) the power to direct those matters that most significantly impacted the activities of the VIE and (ii) the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. For entities that the Company has determined to be VIEs but for which it is not the primary beneficiary, its maximum exposure to loss is the carrying amount of its investments, as the Company has not provided any guarantees other than the guarantee described for PJP VII which was approximately $0.7 million at December 31, 2011 (see Note 4). Also, for all entities determined to be VIEs, the Company does not provide financial support to the real estate ventures through liquidity arrangements, guarantees or other similar commitments. When an entity is not deemed to be a VIE, the Company considers the provisions of the same accounting standard to determine whether a general partner, or the general partners as a group, controls a limited partnership or similar entity when the limited partners have certain rights. The Company consolidates (i) entities that are VIEs and of which the Company is deemed to be the primary beneficiary and (ii) entities that are non-VIEs whichand controlled by the Company controls and in which the limited partners neither

F - 18


have the ability to dissolve the entity noror remove the Company without cause nor any substantive participating rights. Entities that the Company accounts for under the equity method (i.e., at cost, increased or decreased by the Company’sCompany's share of earnings or losses, plus contributions, less distributions and impairments)distributions) include (i) entities that are VIEs and of which the Company is not deemed to be the primary beneficiary (ii) entities that are non-VIEs which the Company does not control, but over which the Company has the ability to exercise significant influence and (iii) entities that are non-VIE’snon-VIEs that the Company controls through its general partner status, but the limited partners in the entity have the substantive ability to dissolve the entity or remove the Company without cause or have substantive participating rights. The Company will reconsidercontinuously assesses its determination of whether an entity is a VIE and who the primary beneficiary is, and whether or not the limited partners in an entity have substantive rights, more particularly if certain events occur that are likely to cause a change in the original determinations. The Company's assessment includes a review of applicable documents such as, but not limited to, applicable partnership agreements, real estate venture agreements, LLC agreements, management and leasing agreements to determine whether the Company has control to direct the business activities of the entities. The portion of thesethe entities that are consolidated but not owned by the Company is presented as non-controlling interest as of and during the periods consolidated. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Management makes significant estimates regarding revenue, valuation of real estate and related intangible assets and liabilities, useful lives of fixed assets, impairment of long-lived assets, equity method investments, allowance for doubtful accounts and deferred costs.
Operating Properties
Operating properties are carried at historical cost less accumulated depreciation and impairment losses. The cost of operating properties reflects their purchase price or development cost. Pursuant to the Company’s adoption of the accounting standard for business combinations as of January 1, 2009, acquisitionAcquisition related costs are expensed as incurred. Prior to the adoption of the accounting standard, acquisition costs were capitalized when incurred. Costs incurred for the renovation and betterment of an operating property are capitalized to the Company’s investment in that property. Ordinary repairs and maintenance are expensed as incurred; major replacements and betterments, which improve or extend the life of the asset, are capitalized and depreciated over their estimated useful lives. Fully-depreciated assets are removed from the accounts.
Purchase Price Allocation
The Company allocates the purchase price of properties to net tangible and identified intangible assets acquired based on fair values. Above-market and below-market in-place lease values for acquired properties are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) the Company’s estimate of the fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease (includes the below market fixed renewal period). Capitalized above-market lease values are amortized as a reduction of rental income over the remaining non-cancelable terms of the respective leases. Capitalized below-market lease values are amortized as an increase to rental income over the remaining non-cancelable terms of the respective leases, including any below market fixed-rate renewal periods.
Other intangible assets also include amounts representing the value of tenant relationships and in-place leases based on the Company’s evaluation of the specific characteristics of each tenant’s lease and the Company’s overall relationship with the respective tenant. The Company estimates the cost to execute leases with terms similar to the remaining lease terms of the in-place leases, including leasing commissions, legal and other related expenses. This intangible asset is amortized to expense over the remaining term of the respective leases and any fixed-rate bargain renewal periods. Company estimates of value are made using methods similar to those used by independent appraisers or by using independent appraisals. Factors considered by the Company in this analysis include an estimate of the carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. In estimating carrying costs, the Company includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, which primarily range from three to twelve months. The Company also considers information obtained about each property as a result of its pre-acquisition due diligence, marketing and leasing activities in estimating the fair value of the tangible and intangible assets acquired. The Company also uses the information obtained as a result of its pre-acquisition due diligence as part of its consideration of the accounting standard governing asset retirement obligations and when necessary, will record a conditional asset retirement obligation as part of its purchase price.

F - 16



Characteristics considered by the Company in allocating value to its tenant relationships include the nature and extent of the Company’s business relationship with the tenant, growth prospects for developing new business with the tenant, the tenant’s credit quality and expectations of lease renewals, among other factors. The value of tenant relationship intangibles is amortized over the

F - 19


remaining initial lease term and expected renewals, but in no event longer than the remaining depreciable life of the building. The value of in-place leases is amortized over the remaining non-cancelable term of the respective leases and any fixed-rate renewal periods.
In the event that a tenant terminates its lease, the unamortized portion of each intangible, including in-place lease values and tenant relationship values, is charged to expense and market rate adjustments (above or below) are recorded to revenue.
Depreciation and Amortization
The costs of buildings and improvements are depreciated using the straight-line method based on the following useful lives: buildings and improvements (five to 55 years) and tenant improvements (the shorter of the lease term or the life of the asset).
The Company's current year consolidated statement of operations contained an out of period depreciation and amortization expense adjustment of $4.7 million relating to intangible assets representing tenant relationships and in-place leases that should have been written off in prior periods. This resulted in the overstatement of depreciation and amortization expense by $4.7 million in the current year. During the year ended December 31, 2010, depreciation and amortization expense was overstated by $1.7 million and was understated by $1.4 million, $1.8 million, $1.7 million and $1.5 million during the years ended December 31, 2009, 2008, 2007, and 2006, respectively. As management believes that this error was not material to prior years' consolidated financial statements and that the impact of recording the error in the current year is not material to the Company's consolidated financial statements, the Company recorded the related adjustment during the current year.
During 2010, the Company also recorded depreciation expense of $1.2$1.2 million related to projects completed in prior years that were not closed out of the Company’s job cost system in a timely manner. This resulted in the understatement of depreciation expense in the prior years. During the years ended December 31, 2009 and 2008, depreciation expense was understated by $0.9$0.9 million and $0.2$0.2 million, respectively. As theseThese errors, both individually and in aggregate, were not material to prior years’ consolidated financial statements and the impact of correcting this error in the current year is not material to the Company’s full year consolidated financial statements, the Company recorded the related adjustments in the current year.statements.
Construction in Progress
Project costs directly associated with the development and construction of a real estate project are capitalized as construction in progress. Construction in progress also includes costs related to ongoing tenant improvement projects. In addition, interest, real estate taxes and other expenses that are directly associated with the Company’s development activities are capitalized until the property is placed in service. Internal direct construction costs totaling $3.4$3.5 million in 2010, $3.92011, $3.4 million in 2009, $5.2 and2010, $3.9 million in 20082009 and interest totaling $10.4$2.0 million in 2010, $8.92011, $10.4 million in 2009,2010, and $16.7$8.9 million in 20082009 were capitalized related to development of certain Properties and land holdings.

During the years ended December 31, 2011, 2010 and 2009, the Company's internal direct construction costs are comprised entirely of capitalized salaries. The following table shows the amount of salaries (including bonuses and benefits) capitalized for the years presented (in thousands):

Impairment or Disposal of Long-Lived Assets
The accounting standard for property, plant and equipment provides a single accounting model for long-lived assets as held-for-sale, broadens the scope of businesses to be disposed of that qualify for reporting as discontinued operations and changes the timing of recognizing losses on such operations.
The Company reviews long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The review of recoverability is based on an estimate of the future undiscounted cash flows (excluding interest charges) expected to result from the long-lived asset’s use and eventual disposition. These cash flows consider factors such as expected future operating income, trends and prospects, as well as the effects of leasing demand, competition and other factors. If impairment exists due to the inability to recover the carrying value of a long-lived asset, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair-value of the property. The Company is required to make subjective assessments as to whether there are impairments in the values of the investments in long-lived assets. These assessments have a direct impact on its net income because recording an impairment loss results in an immediate negative adjustment to net income. The evaluation of anticipated cash flows is highly subjective and is based in part on assumptions regarding future occupancy,

F - 20


rental rates and capital requirements that could differ materially from actual results in future periods. Although the Company’s strategy is generally to hold its properties over the long-term, the Company will dispose of properties to meet its liquidity needs or for other strategic needs. If the Company’s strategy changes or market conditions otherwise dictate an earlier sale date, an impairment loss may be recognized to reduce the property to the lower of the carrying amount or fair value less costs to sell, and such loss could be material. If the Company determines that impairment has occurred and the assets are classified as held and used, the affected assets must be reduced to their fair value.

F - 17


Where properties have been identified as having a potential for sale, additional judgments are required related to the determination as to the appropriate period over which the undiscounted cash flows should include the operating cash flows and the amount included as the estimated residual value. Management determines the amounts to be included based on a probability weighted cash flow. This requires significant judgment. In some cases, the results of whether an impairment is indicated are sensitive to changes in assumptions input into the estimates, including the hold period until expected sale.
During the Company’s impairment review for the yearyears ended December 31, 2011 and 2010, the Company determined that no impairment charges were necessary. For the year ended December 31, 2009, the Company determined that one of its properties, during testing for impairment under the held and used model, had a historical cost greater than the probability-weighted undiscounted cash flows. Accordingly, the recorded amount was reduced to an amount equal to management’s estimate of the then current fair value. This property was sold in the second quarter of the prior year. The Company also recorded an impairment charge on properties designated as held for sale at June 30, 2008 of $6.85 million; these properties were sold during the last quarter of 2008.2009.
The Company entered into development agreements related to two parcels of land under option for ground lease that require the Company to commence development by December 31, 2012.2012. If the Company determines that it will not be able to start the construction by the date specified, or if the Company determines development is not in its best economic interest and an extension of the development period cannot be negotiated, the Company will have to write off all costs that it has incurred in preparing these parcels of land for development amounting to $7.7$7.7 million as of December 31, 2010.2011.
Cash and Cash Equivalents
Cash and cash equivalents are highly-liquid investments with original maturities of three months or less. The Company maintains cash equivalents in financial institutions in excess of insured limits, but believes this risk is mitigated by only investing in or through major financial institutions.
Restricted Cash
Restricted cash consists of cash held as collateral to provide credit enhancement for the Company’s mortgage debt, cash for property taxes, capital expenditures and tenant improvements. Restricted cash is included in other assets as discussed below.
Accounts Receivable and Accrued Rent Receivable
Leases with tenants are accounted for as operating leases. Minimum annual rentals under tenant leases are recognized on a straight-line basis over the term of the related lease. The cumulative difference between lease revenue recognized under the straight-line method and contractual lease payment terms is recorded as “accrued rent receivable, net” on the accompanying balance sheets. Included in current tenant receivables are tenant reimbursements which are comprised of amounts recoverable from tenants for common area maintenance expenses and certain other recoverable expenses that are recognized as revenue in the period in which the related expenses are incurred. As of December 31, 20102011 and 2009,2010, no tenant represented more than 10% of accounts receivable and accrued rent receivable.
Tenant receivables and accrued rent receivables are carried net of the allowances for doubtful accounts of $3.7$3.4 million and $11.6$12.1 million in 2010,2011, respectively and $4.2$3.7 million and $12.2$11.6 million in 2009,2010, respectively. The allowance is an estimate based on two calculations that are combined to determine the total amount reserved. First, the Company evaluates specific accounts where it has determined that a tenant may have an inability to meet its financial obligations. In these situations, the Company uses its judgment, based on the facts and circumstances, and records a specific reserve for that tenant against amounts due to reduce the receivable to the amount that the Company expects to collect. These reserves are reevaluated and adjusted as additional information becomes available. Second, a reserve is established for all tenants based on a range of percentages applied to receivable aging categories for tenant receivables. For accrued rent receivables, the Company considers the results of the evaluation of specific accounts and also considers other factors including assigning risk factors to different industries based on its tenants SIC classification. Considering various factors including assigning a risk factor to different industries, these percentages are based on historical collection and write-off experience adjusted for current market conditions, which requires management’s judgments.

Investments in Unconsolidated Real Estate Ventures
The Company accounts for its investments in unconsolidated Real Estate Ventures under the equity method of accounting as it is not the primary beneficiary (for VIE’s) and the Company exercises significant influence, but does not control these entities under the provisions of the entities’ governing agreements pursuant to the accounting standard for the consolidation of variable interest entities. TheseVIEs. Under the equity method, investments in unconsolidated Real Estate Ventures are recorded initially at cost, as Investments in Real Estate Ventures, and subsequently adjusted for equity in earnings, cash contributions, less distributions and impairments.
On a periodic basis, management also assesses whether there are any indicators that the value of the Company’s 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 value of the investment, as estimated by management. The determination as to whether an impairment exists requires significant management judgment about the fair value of its ownership interest.
The Company’s Broadmoor Joint Venture owns an office park in Austin, Texas which Fair value is currently leaseddetermined through various valuation techniques, including but not limited to, a single tenant who is also a partner in the joint venture. The said tenant is also the owner of the land which the joint venture currently leases under an existing ground lease agreement. The office buildings’ lease renewals are currently under negotiation. Given the current circumstances, the Company performed an impairment assessment of its investment in the venture using probability weighted scenarios that include varying outcomes. The Company believes that adiscounted cash flow models, quoted market participant would assess the probabilities of these outcomes in the same fashion. In evaluating the scenarios, the Company has determined that the fair value of its investment marginally exceeded its carrying valuevalues and the investment is not impaired at December 31, 2010. However, given the lease has not yet been executed and the negotiations of specific terms of the lease are ongoing, the ultimate outcome is uncertain and could cause an impairment of the Company’s investment that could be material.third party appraisals.
To the extent that the Company acquires an interest in or contributes assets to a Real Estate Venture project, the difference between the Company’s cost basis in the investment and the value of the Real Estate Venture or asset contributed is amortized over the life of the related assets, intangibles and liabilities and such adjustment is included in the Company’s share of equity in income of unconsolidated Real Estate Ventures. For purposes of cash flow presentation, distributions from unconsolidated Real Estate Ventures are presented as part of operating activities when they are considered as return on investments. Distributions in excess of the Company’s share in the cumulative unconsolidated Real Estate Ventures’ earnings are considered as return of investments and are presented as part of investing activities in accordance with the accounting standard for cash flow presentation.
Deferred Costs
Costs incurred in connection with property leasing are capitalized as deferred leasing costs. Deferred leasing costs consist primarily of leasing commissions and internal leasing costs that are amortized using the straight-line method over the life of the respective lease which generally ranges from one to 15 years.years. Management re-evaluates the remaining useful lives of leasing costs as economic and market conditions change.
Costs incurred in connection with debt financing are capitalized as deferred financing costs and charged to interest expense over the terms of the related debt agreements. Deferred financing costs consist primarily of loan fees which are amortized over the related loan term on a basis that approximates the effective interest method.

Notes Receivable
As of December 31, 2010,2011, notes receivable included a $7.4$7.2 million purchase money mortgage with a 20 year amortization period that bears interest at 8.5%, a $0.5 million loan (due in 2015) that bears interest at 10%, and a $22.9$23.4 million (including accrued but unpaid interest) seven year purchase money mortgage (due 2016)2016) that bears interest at approximately 6% cash pay/7.64% accrual.

F - 22


The $22.9$23.4 million notes receivable is related to the sale of the two Trenton properties in the prior year2009 and is presented net of the $12.9$12.9 million deferred gain in accordance with the accounting standard for installment sales (the “Trenton Note”). The Company expects to receive $27.8$27.8 million at maturity of the Trenton Note including the difference between the cash payments and the stated accrual rate. See Note 3
The Company periodically assesses the collectability of the notes receivable in accordance with the accounting standard for additional information regardingloan receivables. The Company's $7.2 million outstanding purchase money mortgage note as mentioned above was extended to a buyer (the “Borrower”) of its parcel of land in Newtown, Pennsylvania in December 2006. During 2011, the saleBorrower, who is developing a residential community, defaulted on the note and as a result, a forbearance agreement was entered into between the Company and the Borrower. The Borrower also entered into another forbearance agreement with a third party senior creditor bank related to its own loan. The forbearance agreement between the Company and the Borrower outlined the repayment terms of the outstanding debt and the payment of accrued interest by the Borrower and included, among other things, the metrics for selling and settling on home sales over an agreed period of time. With the inherent credit risk in collecting interest from the note, as provided in the forbearance agreement, the Company will provide a full allowance for any accrued interest receivable. The Company has determined that the loan modification as discussed above represents a troubled debt restructuring since the Borrower was considered to be in a financial difficulty when it defaulted on the two mortgage debts and that a concession was granted in the form of the forbearance agreements. Construction has already recommenced while loan repayments are scheduled to start in 2012. The Company believes that based on terms of the forbearance agreement, the total note will be fully paid by 2014. At December 31, 2011, the Company assessed the status of the metrics outlined in the forbearance agreement and determined that the Borrower will have difficulty meeting its sales targets for the first quarter of 2012. The Borrower provided the Company and the third party senior creditor bank with expected future cash flows analysis showing its ability to meet its sales targets in 2012 to avoid being in default. The Company and the third party senior creditor bank allowed the Borrower to operate under the cash flow assumptions without amending the forbearance agreements. Given the current circumstances, the Company performed an impairment assessment of its note using the expected cash flow information provided by the Borrower and obtained third party documentation to support the assumptions used by the Borrower. The key assumptions used in the cash flow analysis included the revenue per home built; the cost to construct; the general and administrative expenses incurred to operate the business and sell homes; and the absorption assumptions used to determine the rate of home sales. The Company has determined based on the results of its probability weighted cash flow analysis that, as of December 31, 2011, the present value of the expected cash flows of the note receivable exceeded the outstanding balance of the note and therefore the note is recoverable as of December 31, 2011. However, it is still possible that the terms of the forbearance agreement may not be met due to non-performance by the Borrower of the conditions set forth in the said agreement or due to further deterioration in the housing market and could cause a loan loss of the Company's note receivable which could be material to its consolidated results of operations.
As of December 31, 2010, notes receivable included a $7.4 million purchase money mortgage with a 20 year amortization period that bears interest at 8.5%, a $0.8 million loan (due in 2015 including accrued interest) that bears interest at 10%, and a $22.9 million (including accrued but unpaid interest) seven year purchase money mortgage (due 2016) that bears interest at approximately 6% cash pay/7.64% accrual. See related discussion about the Trenton Note.Note above. In December 2010, the Company also extended a loan to one of its unconsolidated Real Estate Venture partners. The said loan bears interest at 10% and will be due including the accrued interest in 2015.2015.
As of December 31, 2009, notes receivable included a $2.8 million purchase money mortgage with a 20 year amortization period that bears interest at 8.5%, a $7.5 million purchase money mortgage with a 20 year amortization period that bears interest at 8.5% and a $22.5 million seven year purchase money mortgage (due 2016) that bears interest at approximately 6% cash pay/7.64% accrual. See related discussion about the Trenton Note above.
The Company periodically assesses the collectibility of the notes receivable in accordance with the accounting standard for loan receivables. On December 29, 2010, the Company foreclosed on one of its note receivables amounting to $2.8$2.8 million (See Note 3 for related discussion). Except for the forecloseddefault on the purchase money mortgage in the current year as discussed above and the foreclosure of note receivables in the currentprior year, there were no other collectibilitycollectability issues noted as of December 31, 20102011 and 2009.2010.
Revenue Recognition
Rental revenue is recognized on the straight-line basis from the later of the date of the commencement of the lease or the date of acquisition of the property subject to existing leases, which averages minimum rents over the terms of the leases. The straight-line rent adjustment increased revenue by approximately $10.9$17.9 million in 2010, $6.42011, $10.9 million in 2009,2010, and $14.0$6.4 million in 2008.2009. Deferred rents on the balance sheet represent rental revenue received prior to their due dates and amounts paid by the tenant for certain improvements considered to be landlord assets that will remain as the Company’s property at the end of the tenant’s lease term. The amortization of the amounts paid by the tenant for such improvements is calculated on a straight-line basis over the term of the tenant’s lease and is a component of straight-line rental income and increased revenue by $2.8$2.4 million in 2010, $2.72011, $2.8 million in 2009,2010, and $2.5$2.7 million in 2008.2009. Lease incentives, which are included as reductions of rental revenue in the accompanying consolidated statements of operations, are recognized on a straight-line basis over the term of the lease. Lease incentives decreased revenue by $1.5$1.6 million in 2010, $1.82011, $1.5 million in 2009,2010, and $0.8$1.8 million in 2008.2009.
Leases also typically provide for tenant reimbursement of a portion of common area maintenance and other operating expenses to the extent that a tenant’s pro rata share of expenses exceeds a base year level set in the lease or to the extent that the tenant has a lease on a triple net basis. For certain leases, significant assumptions and judgments are made by the Company in determining

F - 23


the lease term such as when termination options are provided to the tenant. The lease term impacts the period over which minimum rents are determined and recorded and also considers the period over which lease related costs are amortized. Termination fees received from tenants, bankruptcy settlement fees, third party management fees, labor reimbursement and leasing income are recorded when earned.

F - 20

During 2011, the Company recorded additional income of $0.5 million related to electricity charges in prior years that were under-billed to a certain tenant. This resulted in the overstatement of total revenue by $0.5 million during the current year and in the understatement of total revenue by $0.3 million and $0.2 million for the years ended December 31, 2009 and 2008, respectively. As management believes that this error was not material to prior years' consolidated financial statements and that the impact of recording the error in the current year is not material to the Company's consolidated financial statements, the Company recorded the related adjustment in the current year.


No tenant represented greater than 10% of the Company’s rental revenue in 2011, 2010 2009 or 2008.2009.

Earnings Per ShareUnit
Basic earnings per shareunit is calculated by dividing income allocated to common sharesunits by the weighted-average number of sharesunits outstanding during the period. Diluted earnings per shareunit includes the effect of common shareunit equivalents outstanding during the period.
Treasury Shares
The Company accounts for its treasury share purchases using the cost method. Since repurchase, shares have been reissued at an amount less than their cost basis. The losses on reissuances are charged to the cumulative earnings of the Company using the FIFO basis. As of December 31, 2011, none of the treasury shares remained outstanding. As of December 31, 2010 and 2009,, the total number of treasury shares outstanding was 116,679 shares and 251,764 shares, respectively. shares.
Stock-Based Compensation Plans
The Parent Company maintains a shareholder-approved equity-incentive plan known as the Amended and Restated 1997 Long-Term Incentive Plan (the “1997 Plan”). The 1997 Plan is administered by the Compensation Committee of the Parent Company’s Board of Trustees. Under the 1997 Plan, the Compensation Committee is authorized to award equity and equity-based awards, including incentive stock options, non-qualified stock options, restricted shares and performance-based shares. On June 2, 2010, the Parent Company’s shareholders approved amendments to the 1997 Plan that, among other things, increased the number of common shares available for future awards under the 1997 Plan by 6,000,000 (of which 3,600,000 shares are available solely for options and share appreciation rights). As of December 31, 2010, 6.7 million2011, 5,789,202 common shares remained available for future awards under the 1997 Plan (including those3,971,774 shares available solely for options and share appreciation rights).

The expensed amounts are included in general and administrative expense on the Company’s consolidated income statement in the respective periods.
Comprehensive Income
Comprehensive income or loss is recorded in accordance with the provisions of the accounting standard for comprehensive income. The accounting standard establishes standards for reporting comprehensive income and its components in the financial statements. Comprehensive income includes unrealized gains and losses on available-for-sale securities and the effective portions of changes in the fair value of derivatives.
Accounting for Derivative Instruments and Hedging Activities
The Company accounts for its derivative instruments and hedging activities in accordance with the accounting standard for derivative and hedging activities. The accounting standard requires the Company to measure every derivative instrument (including certain derivative instruments embedded in other contracts) at fair value and record them in the balance sheet as either an asset or liability. See disclosures below related to the Company’s adoption of the accounting standard for fair value measurements and disclosures.
For derivatives designated as fair value hedges, the changes in fair value of both the derivative instrument and the hedged item are recorded in earnings. For derivatives designated as cash flow hedges, the effective portions of changes in the fair value of the derivative are reported in other comprehensive income while the ineffective portions are recognized in earnings. During the year ended December 31, 2009, the Company recorded a $(1.1)$(1.1) million fair value adjustment in its consolidated statements of operations related to two of its interest swaps in which the hedging relationship ceased due to the issuance of its unsecured notes on September 25, 2009. The ineffective portions of the hedges are recognized in earnings. During the year ended December 31, 2009, the Company recognized a gain of $0.1$0.1 million for the ineffective portion of its forward starting swaps prior to the termination of the hedging relationship (See Note 9).

F - 25


The Company actively manages its ratio of fixed-to-floating rate debt. To manage its fixed and floating rate debt in a cost-effective manner, the Company, from time to time, enters into interest rate swap agreements as cash flow hedges, under which it agrees to exchange various combinations of fixed and/or variable interest rates based on agreed upon notional amounts.

F - 22


Fair Value Measurements
The Company estimates the fair value of its outstanding derivatives and available-for-sale-securities in accordance with the accounting standard for fair value measurements and disclosures. The accounting standard defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. It also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value. 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 that 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.
In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

Accounting Pronouncements Adopted During 20102011

In January 2010,June 2011, the FASBFinancial Accounting Standards Board (FASB) issued a newan amendment to the accounting standard for distributionsthe presentation of comprehensive income. The amendment requires entities to stockholders withpresent the total of comprehensive income, the components of stocknet income, and cash. The guidance clarifies thatthe components of other comprehensive income either in calculating earnings per share, an entity should account fora single continuous statement of comprehensive income or in two separate but consecutive statements. In addition, the stock portionamendment requires entities to present on the face of the distribution as a stock issuancefinancial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and not as a stock dividend.

The Company’sCompany's adoption of the new standard didwill not have a material impact on its consolidated financial position or results of operations as no distributions were paid with stock.the amendment relates only to changes in financial statement presentation.

In January 2010,May 2011, the FASB issued an amendmentamendments to the accounting standard for fair value measurements and disclosures. The amendment clarifiesamendments change the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and provides additional disclosure requirements related to recurring and non-recurringfor disclosing information about fair value measurements. Specifically, the guidance revises two disclosure requirements concerningThe amendments are intended to create comparability of fair value measurements presented and clarifies two others. It requires separate presentation of significant transfers intodisclosed in financial statements prepared in accordance with U.S. GAAP and out of Levels 1 and 2 of the fair value hierarchy and disclosure of the reasons for such transfers. Also, it requires the presentation of purchases, sales, issuances and settlements within Level 3 on a gross basis rather than on a net basis. TheInternational Financial Reporting Standards. These amendments clarify that disclosures should be disaggregated by class of asset or liability and that disclosures about inputs and valuation techniques should be provided for both recurring and non-recurring fair value measurements. This amendment isare effective for fiscal years and interim periods endingbeginning after December 15, 2009.2011. The Company’sCompany's adoption of the new standard will not have a material impact on its consolidated financial position or results of operations.
In December 2010, the FASB issued a new accounting standard for the disclosure of supplementary pro-forma information for business combinations. This guidance clarifies that the disclosure of supplementary pro-forma information for business combinations should be presented such that revenues and earnings of the combined entity are calculated as though the relevant business combinations that occurred during the current reporting period had occurred as of the beginning of the comparable prior annual reporting period. The guidance also seeks to improve the usefulness of the supplementary pro-forma information by requiring a description of the nature and amount of material, non-recurring pro-forma adjustments that are directly attributable to the business combinations. This new standard is effective for business combinations with an acquisition date on or after the beginning of the first annual reporting period beginning on or after December 15, 2010. The Company's adoption of this new standard did not have a material impact on its consolidated financial position or results of operations.
In December 2009, the FASB issued a new accounting standard governing transfer of financial assets. This new standard is a revision to the existing accounting standard for the transfer and servicing of financial assets and amends the guidance on accounting for transfers of financial assets, including securitization transactions, where entities have continued exposure to risks related to transferred financial assets. The new accounting standard also expands the disclosure requirements for such transactions. This amendment is effective for fiscal years beginning after November 15, 2009. The Company’s adoption of the new standard did not have a material impact on its consolidated financial position or results of operations.
3.REAL ESTATE INVESTMENTS
In June 2009, the FASB issued an amendment to the accounting and disclosure requirements for the consolidation of VIEs. The elimination of the concept of a qualifying special-purpose entity (QSPE) removes the exception from applying the consolidation guidance within this amendment. This amendment requires an enterprise to perform a qualitative analysis when determining whether or not it must consolidate a VIE. The amendment also requires an enterprise to continuously reassess whether it must consolidate a VIE. Additionally, the amendment requires enhanced disclosures about an enterprise’s involvement with VIEs and any significant change in risk exposure due to that involvement, as well as how its involvement with VIEs impacts the enterprise’s financial statements. Finally, an enterprise will be required to disclose significant judgments and assumptions used to determine whether or not to consolidate a VIE. This amendment was adopted on January 1, 2010 and applied prospectively.

F - 24


As a result of the adoption of the amendment to the accounting and disclosure requirements for the consolidation of VIEs, the Company has determined that it will no longer consolidate three of the VIEs that it has previously consolidated. In reaching its conclusion, the Company considered the requirements provided by the accounting standard to qualitatively assess if the Company was the primary beneficiary of the VIEs based on whether the Company had (i) the power to direct those matters that most significantly impacted the activities of the VIE and (ii) the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. The Company’s consideration included an assessment of each of the entities with which it has involvement and review of applicable documents such as, but not limited to applicable partnership agreements, real estate venture agreements, LLC agreements, management and leasing agreements. As of January 1, 2010, the Company held interests in 17 real estate ventures, 15 of which are unconsolidated and two of which the Company continues to consolidate. The Company’s basis in reaching its conclusion for these entities is provided below:
Previously Consolidated:
Four Tower Bridge and Six Tower Bridge Ventures
Each of the Four Tower Bridge and Six Tower Bridge Real Estate Ventures was formed as a limited partnership to own and manage an office property located in Conshohocken, Pennsylvania. The Company entered into these ventures with two other partners during 1997 and 1998, respectively. The other partner in Four Tower Bridge owns a 35% interest in the partnership entity and the other partner in Six Tower Bridge owns a 37% interest in the partnership entities. These Real Estate Ventures were determined to be VIEs and were previously consolidated in the Company’s financial statements in accordance with the amended accounting standard for the consolidation of VIEs. The Real Estate Ventures were determined to be VIEs due to insufficient equity at the latest reconsideration event. However, upon the Company’s adoption of the new accounting standard on January 1, 2010, the Company has determined that it will no longer consolidate these Real Estate Ventures after it was determined that the partners have shared power in the ventures and no related party considerations were identified. All significant decisions are approved by both partners in the venture. Accordingly, based on the Company’s analysis, the Company deconsolidated these two Real Estate Ventures in accordance with the new accounting standard.
Coppell Associates
Coppell Associates is a Real Estate Venture that owns one property in Austin, Texas. The Company entered into this venture with another partner which owns a 50% interest in the partnership. This Real Estate Venture is a VIE and was previously consolidated in the Company’s financial statements in accordance with the amended accounting standard for the consolidation of VIEs. The venture was determined to be a VIE due to insufficient equity at the latest reconsideration event. However, upon the Company’s adoption of the new accounting standard on January 1, 2010, the Company has determined that it will no longer consolidate this Real Estate Venture after it concluded that the partners have shared power in the venture. All significant decisions are approved by both partners in the venture. Accordingly, based upon the Company’s analysis, the Company deconsolidated this Real Estate Venture in accordance with the new accounting standard.
VIEs that Continue to be Consolidated:
Projects Related to the Company’s Tax Credit Transactions
During 2008, the Company closed two transactions with US Bancorp (“USB”) related to the historic rehabilitation of the 30th Street Post Office now known as the Internal Revenue Service (“IRS”) Philadelphia Campus and the Cira South Garage both located in Philadelphia, Pennsylvania. The real estate ventures created to facilitate the tax credit transactions were considered as VIEs because the equity investment at risk is not sufficient to permit the entities to receive the tax credits without the financial support from USB or because the rights to determine the significant decisions are not vested in the equity. The Company has also concluded that it is the primary beneficiary of the IRS Philadelphia Campus and the Cira South Garage based on the contractual arrangements that obligate the Company to deliver tax benefits and provide other guarantees to USB and that entitle the Company through fee arrangements to receive substantially all available cash flow from the said entities and, accordingly, by design has substantially all the risks of the entities. Please refer to Note 18 for a detailed discussion of these transactions as well as the amount of deferred income related to these VIEs that the Company has included in its consolidated balance sheets. There were no other significant amounts included in the Company’s consolidated balance sheet related to these entities as the related amounts were eliminated during consolidation.
Other VIEs:
PJP VII
The Company holds a 25% interest in a Real Estate Venture that it entered into with two other partners. One of the other partners holds a 50% interest in the venture while the other partner holds a 25% interest. This venture is considered a VIE due to the fact that at the last reconsideration event, it entered into a construction loan to fund the building construction of the property and it was determined that there was insufficient equity in the joint venture. In addition, this loan has not been refinanced as of December 31, 20102011 and the Company guarantees $0.7 million or 8.75% of the total construction note. It is expected that this entity will remain a VIE until the venture refinances the construction loan into a permanent financing. It was determined that the Company does not have the power to direct the significant economic activities of the Real Estate Venture in accordance with the standard and as a result is not the primary beneficiary of this real estate venture.

F - 25


Residence Inn Hotel
The Company holds a 50% interest in a Real Estate Venture that owns a Residence Inn Hotel located in Conshohocken, Pennsylvania. This Real Estate Venture has two other partners, one of which holds a 46.4% interest and the other holds a 3.6% interest. The Real Estate Venture was considered as a VIE in accordance with the amended accounting standard for the consolidation of VIEs due to the participating rights of the non-equity holder hotel manager. However, the Company has determined that the partners have shared power in the venture. All significant decisions are approved by all partners in the venture. Accordingly this Real Estate Venture was not consolidated in the financial statements of the Company. Upon the adoption of the new accounting standard, the Company still has the same determination that it does not have the power to control the business of the Real Estate Venture and that it is still appropriate to account for this venture under the equity method of accounting.
G&I VI Interchange Office LLC
The Company holds a 20% interest in a Real Estate Venture that owns a portfolio of 29 office properties located in Montgomery, Bucks, and Lehigh counties in Pennsylvania. The other partner in this venture holds an 80% ownership interest. The Real Estate Venture was considered as a VIE in accordance with the amended accounting standard for the consolidation of VIEs. The venture continues to be determined a VIE due to the disproportionate voting rights. The Company has determined that it is not the primary beneficiary of the venture. Accordingly, this Real Estate Venture was not consolidated in the financial statements of the Company. Upon the adoption of the new accounting standard, the Company still has the same determination that it does not have the power to control the business of the Real Estate Venture and that it is still appropriate to account for this venture under the equity method of accounting.
Seven Tower Bridge
The Company has a 10% direct limited partnership ownership interest and a 20% ownership in a REIT that has 50% ownership in a Real Estate Venture that anticipates developing a suburban office building in Conshohocken, Pennsylvania. There are three other partners in this venture holding ownership interests of 50%2010, 20%, and 20%, respectively. This venture is considered a VIE as the property is under development and there is insufficient equity to fund the construction. The Company has determined that it is not the primary beneficiary of the venture. Accordingly, this Real Estate Venture was not consolidated in the financial statements of the Company. Upon the adoption of the new accounting standard, the Company still has the same determination that it does not have the power to control the business of the Real Estate Venture and that it is still appropriate to account for this venture under the equity method of accounting.
Other Unconsolidated Real Estate Ventures
In accordance with the Company’s adoption of the accounting standard for the consolidation of VIEs, it was determined that the Company would not consolidate the Real Estate Ventures below based on the evaluation of the substantive participating rights of the partners in each venture under the voting interest model:
Two Tower Bridge (Company as co-General Partner with 35% Ownership Interest)
Eight Tower Bridge (Company as Limited Partner with 3% Preferred Equity Interest)
PJP Real Estate Ventures (Company as Operating Member with 25% to 30% Ownership Interest)
Macquarie BDN Office LLC (Company as Operating Member with 20% Ownership Interest)
Broadmoor Joint Venture (Company as co-Managing Venturer with 50% Ownership Interest)
1000 Chesterbrook (Company as co-General Partner with 50% Ownership Interest)
The “other unconsolidated real estate ventures” described above are not VIEs as the other partners in the ventures have either the substantive participating rights in the entities’ normal business operations or the power to direct the activities is shared amongst the partners. As a result of the Company’s review, it has concluded that it is appropriate to account for these entities as unconsolidated Real Estate Ventures under the equity method of accounting.
Additional Considerations
The supporting real estate venture agreements of the entities listed above provided a straightforward determination of whether the Company has control to direct the business activities of the entities. Where the Company has concluded that control is shared, it is generally because of at least one other partner and the Company must agree on decisions that are considered significant. The Company has also determined that it is not the primary beneficiary in these entities as it does not have the power to direct the activities that most significantly impact the economic performance of these entities. Also, if shared control was determined and the Company was considered to be a related party, the Company is not the party deemed to be the most closely associated with the business. For entities that the Company has determined to be VIEs but for which it is not the primary beneficiary, its maximum exposure to loss is the carrying amount of its investments, as the Company has not provided any guarantees other than the guarantee described for PJP VII which was approximately $0.7 million at December 31, 2010. Also, for all entities determined to be VIEs, the Company does not provide financial support to the real estate ventures through liquidity arrangements, guarantees or other similar commitments, other than perhaps through its general partner standing.

Acquisitions and Dispositions
20102011

Brandywine-AI Venture

On December 20, 2011, the Company formed a joint venture, Brandywine - AI Venture LLC, (the "Venture"), with Current Creek Investments, LLC ("Current Creek"), a wholly-owned subsidiary of Allstate Insurance Company. The Company and Current Creek each own a 50% interest in the Venture. The Venture owns three office properties, which the Company to the Venture upon its formation. The contributed office properties contain an aggregate of 587,317 net rentable square feet of and consist of 3130 and 3141 Fairview Park Drive, both located in Falls Church, Virginia, and 7101 Wisconsin Avenue located in Bethesda, Maryland. Concurrent with the Company's contribution of the three properties to the Venture, Current Creek contributed approximately $32.2 million (net of closing costs and customary prorations) to the capital of the Venture and the Venture closed on non-recourse fixed rate mortgage loans in the aggregate amount of $90.0 million, secured by mortgages on each of the three properties. The mortgage loans have a weighted-average maturity of 7.4 years and bear interest at a weighted average rate of 4.4%. The Venture transferred the properties to the Venture based on a $156.0 million valuation. Upon formation of the Venture, the Company received $120.1 million of aggregate proceeds from these transactions net of $2.9 million of transaction and venture formation costs. The Company used the net proceeds to reduce its outstanding indebtedness under its Prior Credit Facility and for general corporate purposes.

Based on facts and circumstances at Venture formation, the Company has determined that the Venture is not a VIE in accordance with the accounting standard for the consolidation of VIEs. As a result, the Company used the voting interest model under the accounting standard for consolidation to determine if it will consolidate the Venture. Based on the provisions within the joint venture agreement, the Company and Current Creek have shared control rights and the Company does not have exclusive control over the properties. Since control is shared, 3130 Fairview Park and 7101 Wisconsin Avenue were deconsolidated by the Company and are accounted for under the equity method of accounting. The Company recorded a net loss on partial sale of $0.1 million related to these two office properties which is included as part of the loss on venture formation in the Company's consolidated statements of operations together with the related $0.1 million basis adjustment on the Company's equity method investment in the Venture. As of December 31, 2011, the carrying amount of the Company's equity investment in this Venture amounted to $24.7 million.

The Company will continue to maintain a regional management and leasing office in 3141 Fairview Park. Consistent with the other two properties, financial control is shared, however, pursuant to the accounting standard for sales-leaseback transactions, the lease maintained by the Company at 3141 Fairview Park and its 50% ownership interest in the Venture results in the Company having continued involvement that will require the property and its related operations to be consolidated by the Company under the financing method. The Company recorded a mortgage debt of $22.0 million and a $7.5 million financing obligation as part of other liabilities in the Company's balance sheet representing the cash it received from the Venture related to this transaction. The Company recognized a nominal amount of interest expense related to the other partner's portion of the property's operation, from Venture formation through December 31, 2011. As of December 31, 2011, the balance of the financing obligation amounted to $7.5 million.

The Company's continuing involvement with the properties through its interest in the Venture and its management and leasing activities represents a significant continuing involvement in the properties. Accordingly, under the accounting standard for reporting discontinued operations, the Company has determined that the loss on partial sale and the operations of the properties should not be included as part of discontinued operations in its consolidated statements of operations.
Acquisitions
On August 5, 2010,12, 2011, the Company acquired an office property located in Philadelphia, Pennsylvania, together with related ground tenancy rights under a long-term ground lease, through the foreclosure of a note receivable amounting to $18.8 million under which the said property was encumbered. The Company obtained the note receivable from a third party on August 2, 2011 which was funded through an advance under its Credit Facility and with available corporate funds. The office property contains 192,707 of net rentable square feet and is currently 57.2% leased as of December 31, 2011. The Company recognized $0.3 million of transaction costs to acquire the office property which is included as part of general and administrative expenses in the Company's consolidated statements of operations. On the acquisition date of the office property, the total purchase price was allocated as follows: $21.4 million to building, $12.0 million to intangible assets and $14.4 million to below market lease liabilities assumed. The Company also acquired other assets of $0.2 million and assumed certain liabilities of $0.4 million.
On March 28, 2011, the Company acquired two office properties totaling 126,496 of net rentable square feet in Glen Allen, Virginia known as Overlook I and II for $12.6 million. The acquired properties are 100% leased as of December 31, 2011. The Company funded the acquisition price through an advance under its Credit Facility and with available corporate funds. The Company

recognized a nominal amount of acquisition related costs, which are included as part of general and administrative expenses in the Company's consolidated statements of operations.

On January 20, 2011, the Company acquired a one acre parcel of land in Philadelphia, Pennsylvania for $9.3 million. The Company funded the cost of this acquisition with available corporate funds and a draw on its Credit Facility. The Company capitalized $0.5 million of acquisition related and other costs as part of land inventory on its consolidated balance sheet. On December 29, 2011, the Company contributed the acquired property into a newly formed real estate venture known as Brandywine 1919 Market Ventures (the "1919 Ventures") in return for a 50% general partner interest in the venture. 1919 Ventures is expected to construct a mixed-use development property in the city of Philadelphia. The Company has determined that 1919 Ventures is a VIE due to insufficient equity at the date of formation. It was also determined that the Company will not consolidate 1919 Ventures as both partners have shared power in the venture. Prior to the formation of 1919 Ventures, the Company received $4.9 million from the other partner in anticipation of the real estate venture formation. The amount received was accounted for as a distribution from 1919 Ventures and accordingly reduced the Company's equity investment in the venture in the Company's consolidated balance sheet as of December 31, 2011.
Dispositions

On November 22, 2011, the Company sold 442 Creamery Way, a 104,500 net rentable square feet office property located in Exton, PA, for a sales price of $7.4 million. The property was 100.0% occupied as of the date of sale.

On October 28, 2011, the Company sold two office properties (Five Greentree and Lake Center II) containing a total of 206,243 net rentable square feet located in Marlton, NJ for an aggregate sales price of $22.8 million. Five Greentree and Lake Center II were 92.2% and 47.8% occupied, respectively, as of the date of sale.
On October 14, 2011, the Company sold an undeveloped parcel of land in Dallas, Texas containing six acres of land for $0.6 million.
On June 27, 2011, the Company sold Three Greentree Center, a 69,300 net rentable square feet office property located in Marlton, New Jersey, for a sales price of $5.9 million. The property was 13.9% occupied as of the date of sale.
During the first quarter of the 2011, the Company recognized a $2.8 million net gain upon the sale of its remaining 11% ownership interest in three properties which it partially sold to one of its unconsolidated Real Estate Ventures in December 2007. The Company had retained an 11% equity interest in these properties subject to a put/call at fixed prices for a period of three years from the time of the sale. In January 2011, the Company exercised the put/call and transferred full ownership in the three properties to the Real Estate Venture. Accordingly, the Company's direct continuing involvement through its 11% interest in the properties ceased as a result of the transfer of the ownership interest. The Company has also presented the gain as part of its continuing operations in its consolidated statements of operations because of its prior significant continuing involvement with the properties through its interest in the unconsolidated Real Estate Venture and its management and leasing activities at the properties.

The Company accounts for its unconsolidated interests in its Real Estate Ventures using the equity method. The Company’s unconsolidated interests range from 3%20% to 65%, subject to specified priority allocations in certain of the Real Estate Ventures.
The amounts reflected in the following tables (except for the Company’s share of equity and income) are based on the historical financial information of the individual Real Estate Ventures. One of the Real Estate Ventures, acquired in connection with the Prentiss Properties Trust merger in 2006, had a negative equity balance on a historical cost basis as a result of historical depreciation and distribution of excess financing proceeds. The Company reflected its acquisition of this Real Estate Venture interest at its relative fair value as of the date of the purchase of Prentiss.merger. The difference between allocated cost and the underlying equity in the net assets of the investee is accounted for as if the entity were consolidated (i.e., allocated to the Company’s relative share of assets and liabilities with an adjustment to recognize equity in earnings for the appropriate depreciation/amortization). The Company does not record operating losses of the Real Estate Ventures 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.

8.FAIR VALUE OF FINANCIAL INSTRUMENTS
The following fair value disclosure was determined by the Company using available market information and discounted cash flow analyses as of December 31, 20102011 and 2009,2010, 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 measurement of acquiring or assuming 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 estimation methodologies may have a material effect on the estimated fair value amounts. The Company believes that the carrying amounts reflected in the Consolidated Balance Sheets at December 31, 20102011 and 20092010 approximate the fair values for cash and cash equivalents, accounts receivable, other assets, accounts payable and accrued expenses.
The following are financial instruments for which the Company estimates of fair value differ from the carrying amounts (in thousands):

9.RISK MANAGEMENT AND USE OF FINANCIAL INSTRUMENTS
9. RISK MANAGEMENT AND USE OF FINANCIAL INSTRUMENTS
Risk Management
In the course of its on-going business operations, the Company encounters economic risk. There are three main components of economic risk: interest rate risk, credit risk and market risk. The Company is subject to interest rate risk on its interest-bearing liabilities. Credit risk is primarily the risk of inability or unwillingness of tenants to make contractually required payments and counterparties on derivatives not fulfilling their obligations. Market risk is the risk of declines in the value of properties due to changes in rental rates, interest rates or other market factors affecting the valuation of properties held by the Company.

F - 37


Risks and Uncertainties
Significantly challenging currentand sluggish economic conditions have generally resulted in a reduction of the availability of financing and higher borrowing costs. These factors, coupled with a sluggish economy, have reduced the volume of real estate transactions and created credit stresses on mostmany businesses. The Company believes that vacancyVacancy rates may increase through 20112012 and possibly beyond as the current economic climate negatively impacts tenants in the Properties. The current financial markets also have an adverse effect on the Company’s other counter parties such as the counter parties in its derivative contracts.


F - 39


The Company expects that the impact of the current state of the economy, including high unemployment and the unprecedented volatility and illiquidity in the financial and credit markets, will continue to have a dampening effect on the fundamentals of its business, including increases in past due accounts, tenant defaults, lower occupancy and reduced effective rents. These conditions would negatively affect the Company’s future net income and cash flows and could have a material adverse effect on its financial condition.
The Company’s Credit Facility, Bank Term Loan and the indenture governing the unsecured public debt securities (Note 7) contain restrictions, requirements and other limitations on the ability to incur indebtedness, including total debt to asset ratios, secured debt to total asset ratios, debt service coverage ratios and minimum ratios of unencumbered assets to unsecured debt which it must maintain. The ability to borrow under the Credit Facility is subject to compliance with such financial and other covenants. In the event that the Company fails to satisfy these covenants, it would be in default under the Credit Facility, the Bank Term Loan and the indenture and may be required to repay such debt with capital from other sources. Under such circumstances, other sources of capital may not be available, or may be available only on unattractive terms.
Availability of borrowings under the Credit Facility is subject to a traditional material adverse effect clause. Each time the Company borrows it must represent to the lenders that there have been no events of a nature which would have a material adverse effect on the business, assets, operations, condition (financial or otherwise) or prospects of the Company taken as a whole or which could negatively effect the ability of the Company to perform its obligations under the Credit Facility. While the Company believes that there are currently no material adverse effect events, the Company is operating in unprecedented economic times and it is possible that such event could arise which would limit the Company’s borrowings under the Credit Facility. If an event occurs which is considered to have a material adverse effect, the lenders could consider the Company in default under the terms of the Credit Facility and the borrowings under the Credit Facility would become due and payable. If the Company is unable to obtain a waiver, this would have a material adverse effect on the Company’s financial position and results of operations.
The Company was in compliance with all financial covenants as of December 31, 2010.2011. Management continuously monitors the Company’s compliance with and anticipated compliance with the covenants. Certain of the covenants restrict management’s ability to obtain alternative sources of capital. While the Company currently believes it will remain in compliance with its covenants, in the event of a continued slow-down and continued crisis in the credit markets, the Company may not be able to remain in compliance with such covenants and if the lender would not provide a waiver, it could result in an event of default.
Use of Derivative Financial Instruments
The Company’s use of derivative instruments is limited to the utilization of interest rate agreements or other instruments to manage interest rate risk exposures and not for speculative purposes. The principal objective of such arrangements is to minimize the risks and/or costs associated with the Company’s operating and financial structure, as well as to hedge specific transactions. The counterparties to these arrangements are major financial institutions with which the Company and its affiliates may also have other financial relationships. The Company is potentially exposed to credit loss in the event of non-performance by these counterparties. However, because of the high credit ratings of the counterparties, the Company does not anticipate that any of the counterparties will fail to meet these obligations as they come due. The Company does not hedge credit or property value market risks through derivative financial instruments.
The Company formally assesses, both at inception of the hedge and on an on-going basis, whether each derivative is highly-effective in offsetting changes in cash flows of the hedged item. If management determines that a derivative is not highly-effective as a hedge or if a derivative ceases to be a highly-effective hedge, the Company will discontinue hedge accounting prospectively. The related ineffectiveness would be charged to the consolidated statement of operations.

F - 38


The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.
To comply with the provisions of the accounting standard for fair value measurements and disclosures, the Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.

The following table summarizes the terms and fair values of the Company's derivative financial instruments as of December 31, 2011. The Company has no existing derivative financial instruments at December 31, 2010. The notional amounts provide an

(a) Hedging unsecured variable rate debt.

On March 31, 2011, in anticipation of the offering of $325.0 million of 4.95% unsecured guaranteed notes due April 15, 2018, the Company also entered into seven intra-day treasury lock agreements. The treasury lock agreements were designated as cash flow hedges on interest rate risk and qualified for hedge accounting. The total notional amount of the treasury lock agreements was $230.0 million with an expiration of seven years at treasury rates of 2.891%, 2.873%, and 2.858% and a fair value of $0.6 million at March 31, 2011. The agreements were settled on the day we completed the debt offering at a total cost of $0.6 million. This cost was recorded as a component of accumulated other comprehensive income in the accompanying consolidated balance sheet and will be amortized over the term of the note.

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. However, duringin connection with the current year until the maturity of the remainingCompany's interest swaps and as of December 31, 2009,2011, the intra-day treasury lock agreement that the Company entered into and the interest swaps which matured on October 18, 2010, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

The changes in fair values of the hedges during the year ended as of December 31, 2010 and 20092011 were included in other liabilities and accumulated other comprehensive income in the accompanyingCompany's consolidated balance sheet , except for the $1.1$1.1 million fair value adjustment of the hedges charged as an expense to the consolidated statements of operations during the year ended December 31, 2009, relating to two of its interest rate swaps which were both cash settled in December 2009. The hedging relationship with these swaps ceased upon the Company’s issuance of its unsecured notes on September 25, 2009. Accordingly, changes in the fair value of these interest rate swaps were charged to the consolidated statements of operations until they were cash settled. The Company also recognized a gain of $0.1$0.1 million from the ineffectiveness of the hedges during the year ended December 31, 2009 prior to the termination of the hedging relationship.
All of the Company’s existing derivative financial instruments matured on October 18, 2010.
Concentration of Credit Risk
Concentrations of credit risk arise when a number of tenants related to the Company’s investments or rental operations are engaged in similar business activities, or are located in the same geographic region, or have similar economic features that would cause their inability to meet contractual obligations, including those to the Company, to be similarly affected. The Company regularly monitors its tenant base to assess potential concentrations of credit risk. Management believes the current credit risk portfolio is reasonably well diversified and does not contain any unusual concentration of credit risk. No tenant accounted for 10% or more of the Company’s rents during 2011, 2010 2009 and 2008.2009. Recent developments in the general economy and the global credit markets have had a significant adverse effect on companies in numerous industries. The Company has tenants concentrated in various industries that may be experiencing adverse effects from the current economic conditions and the Company could be adversely affected if such tenants go into default on their leases.

11.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 interests held by third party partners in the previously consolidated real estate ventures.
Operating Partnership
As of December 31, 20102011 and 2009,2010, the aggregate book value of the non-controlling interest associated with the redeemable common limited partnership interests in the accompanying consolidated balance sheet was $128.3$33.1 million and $38.3$128.3 million, respectively. 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 $115.4$25.6 million and $32.0$115.4 million, respectively.
12.BENEFICIARIES’ EQUITY OF THE PARENT COMPANY
Non-controlling Interest — Partners’ Share of Previously Consolidated Real Estate Ventures
As discussed in Note 2, as of December 31, 2009, the Company owned interests in three consolidated Real Estate Ventures (Four Tower Bridge, Six Tower Bridge and Coppell Associates) that the Company determined to be VIEs and were consolidated until January 1, 2010. As of December 31, 2009 and prior to their deconsolidation, the aggregate amount related to these non-controlling interests classified within equity was $0.1 million. The Parent Company believes that the aggregate settlement value of these interests was approximately $7.9 million as of December 31, 2009. This amount is based on the estimated liquidation values of the assets and liabilities and the resulting proceeds that the Parent Company would distribute to its real estate venture partners upon dissolution based on book value, as required under the terms of the respective partnership agreements. The partnership agreements of the Real Estate Ventures do not limit the amount that the non-controlling interest partners would be entitled to in the event of liquidation of the assets and liabilities and dissolution of the respective partnerships.
As discussed in Note 2, the Parent Company, upon its adoption of the amendment to the accounting and disclosure requirements for the consolidation of VIEs on January 1, 2010, determined that it will no longer consolidate these VIEs.

12. NON-CONTROLLING INTERESTS IN THE OPERATING PARTNERSHIP
As of December 31, 2009, the Operating Partnership owned interests in three consolidated Real Estate Ventures (see Note 11 above) that own three office properties containing approximately 0.4 million net rentable square feet. These Real Estate Ventures were considered as VIEs under the accounting standard for consolidation. As of December 31, 2009, the aggregate amount related to these non-controlling interests classified within equity was $0.1 million. The Operating Partnership believes that the aggregate settlement value of these interests was approximately $7.9 million as of December 31, 2009. This amount is based on the estimated liquidation values of the assets and liabilities and the resulting proceeds that the Parent Company would distribute to its real estate venture partners upon dissolution, as required under the terms of the respective partnership agreements. The partnership agreements of the Real Estate Ventures do not limit the amount that the non-controlling interest partners would be entitled to in the event of liquidation of the assets and liabilities and dissolution of the respective partnerships.
As discussed in Note 2, the Operating Partnership, upon its adoption of the amendment to the accounting and disclosure requirements for the consolidation of VIEs on January 1, 2010, determined that it will no longer consolidate these VIEs.

On March 2, 2011, the Compensation Committee of the Company's Board of Trustees awarded 174,012 restricted shares to the Company's executives. The restricted shares will cliff vest after three years from the grant date. The vesting of the restricted shares is also subject to acceleration upon a change in control or if the recipient of the award were to die, become disabled, be terminated without cause or retire in a qualifying retirement prior to the vesting date. Qualifying retirement for restricted shares granted on March 2, 2011 as provided in the award agreements Plan means the recipient's voluntary termination of employment after reaching age 57 and accumulating at least 15 years of service with the Company. As of December 31, 2011, none of the Company's executives had met conditions to elect a qualifying retirement.

Restricted Performance Share Units Plan
On March 2, 2011, March 4, 2010 and April 1, 2009, the Compensation Committee of the Parent Company’s Board of Trustees awarded an aggregate of 124,293, 120,955 and 488,292 share-based awards, respectively, to its executives. These awards are referred to as Restricted Performance Share Units, or RPSUs. The RPSUs represent the right to earn common shares. The number of common shares, if any, deliverable to award recipients depends on the Company’sCompany's performance based on its total return to shareholders during the three year measurement period that commenced on January 1, 20102011 (in the case of the March 4, 20102, 2011 awards) and , January 1, 20092010 (in the case of the March 4, 2010 awards) and January 1, 2009 (in the case of the April 1, 2009 awards) and that ends on the earlier of December 31, 2013, December 31, 2012 or December 31, 2011 (as applicable) or the date of a change of control, compared to the total shareholder return of REITs within an index over such respective periods. The awards are also contingent upon the continued employment of the participants through the performance periods (with exceptions for death, disability and qualifying retirement). Dividends are deemed credited to the performance units accounts and are applied to “acquire” more performance units for the account of the unit holder at the price per common share ending on the dividend payment date. If earned, awards will be settled in common shares in an amount that reflects both the number of performance units in the holder’s account at the end of the applicable measurement period and the Company’s total return to shareholders during the applicable three year measurement period relative to the total shareholder return of the REIT within the index.


F - 48


If, based on an industry-based index at the end of the measurement period, the total shareholder return during the measurement period places the Company at or above a certain percentile as compared to its peers then the number of shares that will be delivered shall equal a certain percentage (not to exceed 200%) of the participant’sparticipant's base units.
The fair valuesunits. In the case of the 2010 andApril 1, 2009 awards award, a total of 372,101 shares were determined to be deliverable to award recipients on the grant dates were $2.0 million and $1.1 million, respectively, and are being amortized over the March 1, 2012. These shares, which all vested on December 31, 2011 (the end of its three year cliff vesting period. -year measurement period), were also paid cash dividends on January 19, 2012.
On the date of each grant, the awards were valued using a Monte Carlo simulation. The fair values of the 2011 and 2010 awards on the grant dates were $2.0 million, respectively, while the 2009 award was $1.1 million. The fair values of each award are being amortized over the three year cliff vesting period. In the case of the 2011 awards, the vesting of the RPSUs is also subject to acceleration upon a change in control or if the recipient of the award were to die, become disabled, terminated without cause or retire in a qualifying retirement prior to the vesting date. Qualifying retirement for restricted shares granted on March 2, 2011 as provided under the 1997 Plan means the recipient's voluntary termination of employment after reaching age 57 and accumulating at least 15 years of service with the Company. As of December 31, 2011, none of the Company's executives has met conditions to elect a qualifying retirement.
During the year ended December 31, 2010,2011, the Company recognized total compensation expense for both the 2011, 2010 and 2009 awards of $0.6$1.7 million and $0.4 million, respectively, related to this plan, of which nominal amounts were$0.5 million was capitalized as part of the Company’s review of employee salaries eligible for capitalization.

Outperformance Program
On August 28, 2006, the Compensation Committee of the Parent Company’s Board of Trustees adopted a long-term incentive compensation program (the “outperformance program”) under the 1997 Plan. The outperformance program provided for share-based awards, with share issuances (if any), to take the form of both vested and restricted common shares and with any share issuances contingent upon the Company’s total shareholder return during a three year measurement period exceeding specified performance hurdles. These hurdles were not met and, accordingly, no shares were delivered under the outperformance program and the outperformance program, has terminated in accordance with its terms. The awards under the outperformance program were accounted for in accordance with the accounting standard for stock-based compensation. The aggregate grant date fair values of the awards under the outperformance program, as adjusted for estimated forfeitures, were approximately $5.9$5.9 million (with the values determined through a Monte Carlo simulation) and are being amortized into expense over the five-yearfive-year vesting period beginning on the grant dates using a graded vesting attribution model. For the years ended December 31, 2011, 2010 2009 and 2008,2009, the Company recognized $0.4$0.1 million $0.9, $0.4 million and $1.0$0.9 million, respectively, of compensation expense related to the outperformance program; $0.1 million remains to be recognized as compensation expenseprogram. The grant date fair value is fully amortized as of December 31, 2010.2011.
Employee Share Purchase Plan
On May 9, 2007, the Parent Company’s shareholders approved the 2007 Non-Qualified Employee Share Purchase Plan (the “ESPP”). The ESPP is intended to provide eligible employees with a convenient means to purchase common shares of the Parent Company through payroll deductions and voluntary cash purchases at an amount equal to 85% of the average closing price per share for a specified period.period. Under the plan document, the maximum participant contribution for the 20102011 plan year is limited to the lesser of 20% of compensation or $50,000.$50,000. The number of shares reserved for issuance under the ESPP is 1.25 million.million. During the year ended December 31, 2010,2011, employees made purchases of $0.5$0.4 million under the ESPP and the Company recognized $0.2$0.1 million of compensation expense related to the ESPP. During the year ended December 31, 2009,2010, employees made purchases of $0.4$0.5 million under the ESPP and the Company recognized $0.3$0.2 million of compensation expense related to the ESPP. During the year ended December 31, 2008,2009, employees made purchases of $0.6$0.4 million under the ESPP and the Company recognized $0.1$0.3 million of compensation expense related to the ESPP. The Board of Trustees of the Parent Company may terminate the ESPP at its sole discretion at anytime.
Deferred Compensation
In January 2005, the Parent Company adopted a Deferred Compensation Plan (the “Plan”) that allows trustees and certain key employees to voluntarily defer compensation. Compensation expense is recorded for the deferred compensation and a related liability is recognized. Participants may elect designated benchmark investment options for the notional investment of their deferred compensation. The deferred compensation obligation is adjusted for deemed income or loss related to the investments selected. At the time the participants defer compensation, the Company records a liability, which is included in the Company’s consolidated balance sheet. The liability is adjusted for changes in the market value of the participants’ selected investments at the end of each accounting period, and the impact of adjusting the liability is recorded as an increase or decrease to compensation cost. For the yearsyear ended December 31, 2010 and 2009,2011, the Company recorded a nominalnet increasedecrease in compensation costs of $1.0 million and $1.5 million, respectively, in connection with the Plan due to the change in market value of the participant investments in the Plan. For the yearyears ended December 31, 2008, 2010 and 2009,

F - 49


the Company recorded a net reductionincrease in compensation costcosts of $2.8$1.0 million and $1.5 million, respectively, in connection with the Plan due to the change in market value of the participant investments in the Plan.
The deferred compensation obligations are unfunded, but the Company has purchased company-owned life insurance policies and mutual funds, which can be utilized as a future funding source for the Company’s obligations under the Plan. Participants in the Plan have no interest in any assets set aside by the Company to meet its obligations under the Plan. For the yearsyear ended December 31, 2011, the Company recorded a net increase in compensation costs of $0.1 million. For the years ended December 31, 2010 and 2009, the Company recorded a net reduction in compensation costcosts of $1.0$1.0 million and $1.8$1.8 million, respectively and net increase in compensation cost of $2.7 million during the year ended December 31, 2008,, in connection with the investments in the Company-owned policies and mutual funds.
Participants in the Plan may elect to have all or a portion of their deferred compensation invested in the Company’s common shares. The Company holds these shares in a rabbi trust, which is subject to the claims of the Company’s creditors in the event of the Company’s bankruptcy or insolvency. The Plan does not provide for diversification of a participant’s deferral allocated to the Company common share and deferrals allocated to Company common share can only be settled with a fixed number of shares. In accordance with the accounting standard for deferred compensation arrangements where amounts earned are held in a rabbi trust and invested, the deferred compensation obligation associated with Company’s common shares is classified as a component of shareholder’s equity and the related shares are treated as shares to be issued and are included in total shares outstanding. At December 31, 20102011 and 2009, 2010, 0.3 million of such shares, respectively, were included in total shares outstanding. Subsequent changes in the fair value of the common shares are not reflected in operations or shareholders’ equity of the Company.

On November 17, 2008, the Company closed a transaction with US Bancorp (“USB”) related to the historic rehabilitation of the IRS Philadelphia Campus, a 862,692 square foot office building that is 100% leased to the IRS. On August 27, 2010, the Company completed the development of the IRS Philadelphia Campus and the IRS lease commenced. USB agreed to contribute approximately $64.8$64.1 million of project costs and advanced $10.2$10.2 million of that amount contemporaneously with the closing of the transaction. USB subsequently advanced an additional $27.4$27.4 million and $23.8$23.8 million in June 2010 and December 2009, respectively. TheOn October 19, 2011, the Company received the remaining $3.4$2.7 million will be advanced of the total contributions upon the Company’sits completion of certain items and compliance with the federal rehabilitation regulations.
In exchange for its contributions into the development of IRS Philadelphia Campus, USB is entitled to substantially all of the benefits derived from the tax rehabilitation credits available under section 47 of the Internal Revenue Code. USB does not have a material interest in the underlying economics of the property. This transaction includes a put/call provision whereby the Company may be obligated or entitled to repurchase USB’s interest in the IRS Philadelphia Campus. The Company believes the put will be exercised and the amount attributed to that puttable non-controlling interest obligation is included in other liabilities and is being accreted to the expected fixed put price.

F - 48


Based on the contractual arrangements that obligate the Company to deliver tax benefits and provide other guarantees to USB and that entitle the Company through fee arrangements to receive substantially all available cash flow from the IRS Philadelphia Campus, the Company concluded that the IRS Philadelphia Campus should be consolidated. The Company also concluded that

capital contributions received from USB, in substance, are consideration that the Company receives in exchange for its obligation to deliver tax credits and other tax benefits to USB. These receipts other than the amounts allocated to the put obligation will be recognized as revenuehistoric tax credit transaction income in the consolidated financial statements beginning when the obligation to USB is relieved which occurs upon delivery of the expected tax benefits net of any associated costs. The tax credit is subject to 20% recapture per year beginning one year after the completion of the IRS Philadelphia Campus. The total USB contributions made amounting to $61.4 million as of December 31, 2010 and $34.0 million as of December 31, 2009 are presented within deferred income in the Company’sCompany's consolidated balance sheet.sheet amounted to to $51.6 million as of December 31, 2011 and $61.4 million as of December 31, 2010, respectively. The contributions were recorded net of the amount allocated to non-controlling interest as described above of $2.1$2.4 million and $1.1$2.1 million at December 31, 2011 and December 31, 2010 and December 31, 2009,, respectively. The Company anticipates that beginningBeginning in September 2011 itto September 2015, the Company recognized and will recognize the cash received as revenue net of allocated expenses over the five year tax credit recapture period as defined in the Internal Revenue Code with within other income (expense) in its consolidated statements of operations. TheDuring the year ended December 31, 2011, the Company also expects thatrecognized $12.0 million of the put/call provision will be exercisedcash received as revenue net of $0.5 million of allocated expenses within other income (expense) in December 2015 when the recapture period ends.its consolidated statements of operations.
Direct and incremental costs incurred in structuring the transaction are deferred and will be recognized as expense in the consolidated financial statements upon the recognition of the related revenue as discussed above. The deferred costs at December 31, 20102011 and 20092010 are $4.3$2.1 million and $2.4$4.3 million, respectively, and are included in other assets on the Company’s consolidated balance sheet. Amounts included in interest expense related to the accretion of the non-controlling interest liability and the 2% return expected to be paid to USB on its non-controlling interest aggregate to $1.1$1.3 million, $1.1 million and $0.2 million for year-ended years ended December 31, 2010.2011, 2010 and 2009, respectively.
New Markets Tax Credit Transaction
On December 30, 2008, the Company entered into a transaction with USB related to the Cira South Garage in Philadelphia, Pennsylvania and expects to receive a net benefit of $7.8$7.8 million under a qualified New Markets Tax Credit Program (“NMTC”). The NMTC was provided for in the Community Renewal Tax Relief Act of 2000 (the “Act”) and is intended to induce investment capital in underserved and impoverished areas of the United States. The Act permits taxpayers (whether companies or individuals) to claim credits against their Federal income taxes for up to 39% of qualified investments in qualified, active low-income businesses or ventures.
USB contributed $13.3$13.3 million into the development of the Cira South Garage and as such it is entitled to substantially all of the benefits derived from the tax credit, but it does not have a material interest in the underlying economics of the Cira South Garage. This transaction also includes a put/call provision whereby the Company may be obligated or entitled to repurchase USB’s interest. The Company believes the put will be exercised and an amount attributed to that obligation is included in other liabilities and is being accreted to the expected fixed put price. The said put price is insignificant.
Based on the contractual arrangements that obligate the Company to deliver tax benefits and provide various other guarantees to USB, the Company concluded that the investment entities established to facilitate the NMTC transaction should be consolidated. The USB contribution of $13.3$13.3 million is included in deferred income on the Company’s consolidated balance sheet at December 31, 2011 and December 31, 2010 and December 31, 2009.. The USB contribution other than the amount allocated to the put obligation will be recognized as income in the consolidated financial statements when the tax benefits are delivered without risk of recapture to the tax credit investors and the Company’s obligation is relieved. The Company anticipates that it will recognize the net cash received as revenue within other income/expense in the year ended December 31, 2015.2015. The NMTC is subject to 100% recapture for a period of seven years as provided in the Internal Revenue Code. The Company expects that the put/call provision will be exercised in December 2015 when the recapture period ends.
Direct and incremental costs incurred in structuring the transaction are deferred and will be recognized as expense in the consolidated financial statements upon the recognition of the related revenue as discussed above. The deferred cost at December 31, 20102011 and 20092010 is $5.3$5.3 million and is included in other assets on the Company’s consolidated balance sheet.

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

Legal Proceedings
The Company is involved from time to time in litigation on various matters, including disputes with tenants and disputes arising out of agreements to purchase or sell properties. Given the nature of the Company’s business activities, these lawsuits are considered routine to the conduct of its business. The result of any particular lawsuit cannot be predicted, because of the very nature of litigation, the litigation process and its adversarial nature, and the jury system. The Company 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.

One of the land leases provides for contingent rent participation by the lessor in certain capital transactions and net operating cash flows of the property 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, nor any reimbursed expenses.

The Company acquired ground tenancy rights under a long term ground lease agreement related to its acquisition of an office building in Philadelphia, Pennsylvania on August 12, 2011. The annual rental payments under this ground lease is equal to a percentage of the NOI generated by the property. The Company has not included the amounts in the table above since such amounts are not fixed or determinable.
The Company also acquired ground tenancy rights under a long term ground lease agreement through its acquisition of Three Logan Square on August 5, 2010.2010. The annual rental payment under this ground lease is ten dollars through August 2022 which is when the initial term of the ground lease will end. After the initial term, the Company has the option to renew the lease until 2091.2091. The Company also has the option to purchase the land at fair market value after providing a written notice to the owner. The annual rental payment after 2022 will be adjusted at the lower of $3.0$3.0 million or the prevailing market rent at that time until 2030. Subsequent to 2030, the annual rental payment will be adjusted at the lower of $4.0$4.0 million or the prevailing market rent at the time until 2042 and at fair market value until 2091. The Company believes that based on conditions as of the date the lease was assigned (August(August 5, 2010)2010), the lease will reset to market after the initial term. Using the estimated fair market rent as of the date of the acquisition over the extended term of the ground lease (assuming the purchase option is not exercised), the future payments will aggregate to $27.4 million.$27.4 million. The Company has not included the amounts in the table above since such amounts are not fixed and determinable.
Other Commitments or Contingencies
As part of the Company’s September 2004 acquisition of a portfolio of properties from The Rubenstein Company (which the Company refers to as the TRC acquisition), the Company acquired its interest in Two Logan Square, a 706,288708,844 square foot office building in Philadelphia, primarily through its ownership of a second and third mortgage secured by this property. This property is consolidated as the borrower is a variable interest entity and the Company, through its ownership of the second and third mortgages, is the primary beneficiary. The Company currently does not expect to take title to Two Logan Square until, at the earliest, September 2019.2019. If the Company takes fee title to Two Logan Square upon a foreclosure of its mortgage, the Company has agreed to pay an unaffiliated third party that holds a residual interest in the fee owner of this property an amount equal to $2.9 million.$2.9 million. On the TRC acquisition date, the Company recorded a liability of $0.7$0.7 million and this amount will accrete up to $2.9$2.9 million through September 2019.2019. As of December 31, 2010,2011, the Company has a balance of $1.2$1.3 million for this liability in its consolidated balance sheet.

The Company is currently has been audited by the Internal Revenue Service (the “IRS”) for its 2004 tax year. The audit concernsconcerned the tax treatment of the TRC acquisition in September 2004 in which the Company acquired a portfolio of properties through the acquisition of a limited partnership. On December 17, 2010, the Company received notice that the IRS proposed an adjustment to the allocation of recourse liabilities allocated to the contributor of the properties. The Company intends to appealhas appealed the proposed adjustment. The proposed adjustment, if upheld, would not result in a material tax liability for the Company. However, an adjustment could raise a question as to whether a contributor of partnership interests in the 2004 transaction could assert a claim against the Company under the tax protection agreement entered into as part of the transaction.

As part of the Company’s 2006 acquisition ofmerger with Prentiss Properties Trust, (the “Prentiss acquisition”) and the 2004 TRC acquisition in 2004,and several of the Company's other transactions, the Company agreed not to sell certain of the properties it acquired in transactions that would trigger taxable income to the former owners. In the case of the TRC acquisition, the Company agreed not to sell acquired properties for periods up to 15 years  from the date of the TRC acquisition as follows at December 31, 2010:2011: One Rodney Square and 130/150/170 Radnor Financial Center (January 2015); and One Logan Square, Two Logan Square and Radnor Corporate Center (January 2020). In the Prentiss acquisition, the Company assumed the obligation of Prentiss not to sell Concord Airport Plaza before March 2018. The Company’s agreements generally provide that it may dispose of the subject properties only in transactions that qualify as tax-free exchanges under Section 1031 of the Internal Revenue Code or in other tax deferred transactions. If the Company were to sell a restricted property before expiration of the restricted period in a non-exempt transaction, the Company may be required to make significant payments to the parties who sold the applicable property on account of tax liabilities attributed to them.
As part of the Company’s acquisition of properties from time to time in tax-deferred transactions, the Company has agreed to provide certain of the prior owners of the acquired properties with the right to guarantee the Company’s indebtedness. If the Company were to seek to repay the indebtedness guaranteed by the prior owner before the expiration of the applicable agreement, the Company will be required to provide the prior owner an opportunity to guaranty a qualifying replacement debt. These debt maintenance agreements may limit the Company’s ability to refinance indebtedness on terms that will be favorable to the Company.
The Company invests in its properties and regularly incurs capital expenditures in the ordinary course to maintain the properties. The Company believes that such expenditures enhance its competitiveness. The Company also enters into construction, utility and service contracts in the ordinary course of business which may extend beyond one year. These contracts typically provide for cancellation with insignificant or no cancellation penalties.
During 2008, in connection with the development of the IRS Philadelphia Campus and the Cira South Garage, the Company entered into a historic tax credit and a new market tax credit arrangement (see Note 18)16), respectively. The Company is required to be in compliance with various laws, regulations and contractual provisions that apply to its historic and new market tax credit arrangements. Non-compliance with applicable requirements could result in projected tax benefits not being realized and require a refund or reduction of investor capital contributions, which are reported as deferred income in the Company’s consolidated balance sheet, until such time as its obligation to deliver tax benefits is relieved. The remaining compliance periods for its tax credit arrangements runs through 2015.2015. The Company does not anticipate that any material refunds or reductions of investor capital contributions will be required in connection with these arrangements.
23.21. SUBSEQUENT EVENT

The Company fundedhas evaluated subsequent events through the cost of this acquisition with available corporate cash and a draw on its Credit Facility.

This resulted in the overstatement of our job cost system in a timely manner resultingtotal revenue by $0.5 million during the current year and in the understatement of depreciation expense in the prior yearstotal revenue by $0.3 million and prior quarters. The adjustment related to different quarters during the year and resulted in the understatement of net losses of the affected quarters. Understatement of depreciation expense$0.2 million for the first, second,years ended December 31, 2009 and third quarters of the current year amounted to $0.4 million, $0.3 million, and $0.5 million,2008, respectively. In addition, the Company recorded other adjustments in prior quarters of 2010. In aggregate, all adjustments including the aforementioned adjustments understated or (overstated) the reported net loss by ($0.5) million in the third quarter; and $0.4 million and $0.2 million for the first and second quarters, respectively. See also the disclosure under the caption depreciation and amortization in Note 2. As the Company had concludedmanagement believes that these errors, both individually and in aggregate, werethis error was not material to prior years’years' consolidated financial statements and that the impact of correcting thisrecording the error in the current year is not material to the Company’s full yearCompany's consolidated financial statements, the Company recorded the related adjustmentsadjustment in the current year.
(b)
The consolidated statement of operations for the second quarter of 2011 also contained an out of period depreciation and amortization expense adjustment of $4.7 million relating to intangible assets representing tenant relationships and in-place leases that should have been written off in prior periods. This resulted in the overstatement of depreciation and amortization expense by $4.7 million million in the current year. During the year ended December 31, 2010, depreciation and amortization expense was overstated by $1.7 million and was understated by $1.4 million, $1.8 million, $1.7 million and $1.5 million during the years ended December 31, 2009, 2008, 2007, and 2006, respectively. As management believes that this error was not material to prior years' consolidated financial statements and that the impact of recording the error in the current year is not material to the Company's consolidated financial statements, the Company recorded the related adjustment during the current year.
The summation of quarterly earnings per share amounts do not necessarily equal the full year amounts. The above information was updated to reclassify amounts previously reported to reflect discontinued operations. See Note 2 and Note 10.
