WASHINGTON REAL ESTATE INVESTMENT TRUST AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

SEPTEMBER 30, 2011

(UNAUDITED)

NOTE 1: NATURE OF BUSINESS

Washington Real Estate Investment Trust (“We” or “WRIT”), a Maryland real estate investment trust, is a self-administered, self-managed equity real estate investment trust, successor to a trust organized in 1960. Our business consists of the ownership and development of income-producing real estate properties in the greater Washington metro region. We own a diversified portfolio of office buildings, medical office buildings, industrial/flex centers, multifamily buildings and retail centers.

Federal Income Taxes

We believe that we qualify as a real estate investment trust (“REIT”) under Sections 856-860 of the Internal Revenue Code and intend to continue to qualify as such. To maintain our status as a REIT, we are required to distribute 90% of our ordinary taxable income to our shareholders. When selling properties, we have the option of (a) reinvesting the sales proceeds of properties sold, allowing for a deferral of income taxes on the sale, (b) paying out capital gains to the shareholders with no tax to WRIT or (c) treating the capital gains as having been distributed to the shareholders, paying the tax on the gain deemed distributed and allocating the tax paid as a credit to the shareholders.

Generally, and subject to our ongoing qualification as a REIT, no provisions for income taxes are necessary except for taxes on undistributed REIT taxable income and taxes on the income generated by our taxable REIT subsidiaries (“TRS’s”). Our TRS’s are subject to corporate federal and state income tax on their taxable income at regular statutory rates.

On August 5, 2011, we entered into five separate purchase and sale agreements to effectuate the sale of our entire industrial segment and two office assets for an aggregate purchase price of $350.0 million. On September 2, 2011, we closed the first three of the purchase and sale agreements, for an aggregate $235.8 million. We closed on the remaining two purchase and sale agreements subsequent to the end of the quarter. We recognized a $56.6 million gain on sale of real estate during the third quarter of 2011 in connection with the first three purchase and sale agreements. A portion of the capital gains from the sales were reinvested in replacement properties, with the remainder to be paid out to the shareholders.

NOTE 2: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION

Significant Accounting Policies

We have prepared our consolidated financial statements using the accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2010.

Principles of Consolidation and Basis of Presentation

The accompanying unaudited consolidated financial statements include the consolidated accounts of WRIT, its majority-owned subsidiaries and entities in which WRIT has a controlling interest, including where WRIT has been determined to be a primary beneficiary of a variable interest entity (“VIE”). All intercompany balances and transactions have been eliminated in consolidation.

We have prepared the accompanying unaudited financial statements pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to those rules and regulations, although we believe that the disclosures made are adequate to make the information presented not misleading. In addition, in the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the results for the periods presented have been included. These unaudited financial statements should be read in conjunction with the financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2010.

Within these notes to the financial statements, we refer to the three months ended September 30, 2011 and September 30, 2010 as the “2011 Quarter” and the “2010 Quarter”, respectively, and the nine months ended September 30, 2011 and September 30, 2010 as the “2011 Period” and “2010 Period”, respectively.

Use of Estimates in the Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make certain 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 revenues and expenses during the reporting period. Actual results could differ from those estimates.

Reclassifications

Certain prior year amounts have been reclassified to conform to the current year presentation due to the reclassification of certain properties as discontinued operations (see note 3 to the consolidated financial statements).

NOTE 3: REAL ESTATE ACQUISITIONS AND DISCONTINUED OPERATIONS

Acquisitions

WRIT acquired the following properties and land for development during the 2011 Period:

Acquisition Date |  | Property Name |  | Property Type |  | Rentable Square Feet |  |  | Contract Purchase Price (in thousands) |
January 11, 2011 |  | 1140 Connecticut Avenue |  | Office |  |  | 184,000 |  |  | $ | 80,250 |
March 30, 2011 |  | 1227 25th Street |  | Office |  |  | 130,000 |  |  |  | 47,000 |
June 15, 2011 |  | 650 North Glebe Road(1) |  | Multifamily |  |  | N/A |  |  |  | 11,800 |
August 30, 2011 |  | Olney Village Center |  | Retail |  |  | 199,000 |  |  |  | 58,000 |
September 13, 2011 |  | Braddock Metro Center |  | Office |  |  | 345,000 |  |  |  | 101,000 |
September 15, 2011 |  | John Marshall II |  | Office |  |  | 223,000 |  |  |  | 73,500 |
|  |  |  | Total |  |  | 1,081,000 |  |  | $ | 371,550 |

(1) | 650 North Glebe Road is 37,000 square feet of land acquired by a consolidated joint venture for the purpose of developing an apartment community. WRIT is a 90% owner of the joint venture.

The results of operations from the acquired operating properties are included in the consolidated statements of income as of their acquisition dates.

The revenue and earnings of our 2011 acquisitions are as follows (amounts in thousands):

|  | Quarter Ended September 30, 2011 |  |  | Period Ended September 30, 2011 |
Real estate revenues |  | $ | 4,376 |  |  | $ | 9,458 |
Net income |  | $ | 292 |  |  | $ | 730 |

We have recorded the total purchase price of the above acquisitions as follows (in millions):

|  | Recordation of Purchase Price |
|  | 2011 |
Land |  | $ | 90.9 |
Buildings |  |  | 219.6 |
Tenant origination costs |  |  | 15.7 |
Leasing commissions/absorption costs |  |  | 29.7 |
Net lease intangible assets |  |  | 6.8 |
Net lease intangible liabilities |  |  | (2.5 | )
Fair value of assumed mortgages |  |  | (78.5 | )
Total |  | $ | 281.7 |

The weighted remaining average life in months for the components above, other than land and building, are 65 months for tenant origination costs, 54 months for leasing commissions/absorption costs, 68 months for net lease intangible assets and 65 months for net lease intangible liabilities.

The difference in total contract purchase price of $371.6 million and the acquisition cost per the consolidated statements of cash flows of $281.7 million is primarily related to the two mortgage notes assumed for $76.7 million relating to John Marshall II and Olney Village Center, cash paid for the acquisition of land at 650 North Glebe Road for $11.8 million included in development, and credits received at settlement totaling $1.3 million.

The following unaudited pro forma combined condensed statements of operations present the consolidated results of operations for the 2011 Quarter and Period and the 2010 Quarter and Period, as if the above described acquisitions had occurred at the beginning of the year prior to the acquisition. The unaudited pro forma information does not purport to be indicative of the results that actually would have occurred if the acquisitions had been in effect for the Quarters and Periods presented. The unaudited data presented is in thousands, except per share data.

Noncontrolling Interests in Subsidiaries

We entered into an operating partnership agreement with a member of the entity that previously owned Northern Virginia Industrial Park II in conjunction with the acquisition of this property in May 1998. We account for this activity by applying the noncontrolling owner’s percentage ownership interest to the net income of the property and reporting such amount in our net income attributable to noncontrolling interests. Subsequent to the end of the 2011 Quarter, we closed on the sale of Northern Virginia Industrial Park II (see next section), thereby terminating this noncontrolling interest in our earnings. Accordingly, the total amounts reported on the consolidated statements of income for noncontrolling interests are related to discontinued operations.

##### Table of Contents

Discontinued Operations

We dispose of assets (sometimes using tax-deferred exchanges) that no longer meet our long-term strategy or return objectives and where market conditions for sale are favorable. The proceeds from the sales may be reinvested into other properties, used to fund development operations or to support other corporate needs, or distributed to our shareholders. Properties are considered held for sale when they meet the criteria specified by GAAP. Depreciation on these properties is discontinued at that time, but operating revenues, other operating expenses and interest continue to be recognized until the date of sale.

On August 5, 2011 we entered into five separate purchase and sale agreements to effectuate the sale of our entire industrial segment and two office assets (the Crescent and Albemarle Point) for an aggregate purchase price of $350.0 million. On September 2, 2011, we closed the first three of the purchase and sale agreements, for an aggregate $235.8 million. We closed on the remaining two purchase and sale agreements subsequent to the end of the quarter. We recognized a $56.6 million gain on sale of real estate during the 2011 Quarter in connection with the first three purchase and sale agreements.

The impact of the disposal of our industrial segment on revenues and net income is summarized as follows (amounts in thousands, except per share data):

|  | Quarter Ended September 30, |  |  | Period Ended September 30, |
|  | 2011 |  |  | 2010 |  |  | 2011 |  |  | 2010 |

The operating loss for Dulles Station I for the 2011 Period includes a $0.6 million impairment charge to reflect the property’s fair value less any selling costs based on its contract sales price.

NOTE 4: MORTAGE NOTES PAYABLE

On August 30, 2011, we assumed a $22.6 million mortgage note as partial consideration for the acquisition of Olney Village Center. This mortgage note bears interest at 6.37% per annum. The fair value interest rate on this mortgage note is 4.94%, based on quotes obtained for similar loans. We recorded the mortgage at its fair value of $24.4 million. Principal and interest are payable monthly until November 1, 2023, at which time all unpaid principal and interest are payable in full.

On September 15, 2011, we assumed a $54.1 million mortgage note as partial consideration for the acquisition of John Marshall II. This mortgage note bears interest at 5.79% per annum, which approximates its fair value interest rate, based on quotes obtained for similar loans. Principal and interest are payable monthly until May 6, 2016, at which time all unpaid principal and interest are payable in full.

On September 1, 2011, we repaid without penalty the remaining $9.1 million of principal on the mortgage note secured by Shady Grove Medical Village II.

Subsequent to the end of 2011 Quarter, on October 5, 2011, we entered into an amendment to the purchase and sale agreement for 6100 Columbia Park Road and Dulles Business Park , under which we agreed to seek prepayment of the mortgage notes secured by Dulles Business Park prior to closing the sale. Under the terms of the amendment, if we prepaid the mortgage notes prior to November 1, 2011, then the sales price would be increased by $875,000 in order to partially offset the penalties incurred by us for the prepayment of the mortgage notes. On October 7, 2011, we prepaid the remaining $17.9 million of principal on the mortgage notes, incurring prepayment penalties of approximately $1.0 million. Because Dulles Business Park is considered held for sale as of September 30, 2011 (see note 3 to the consolidated financial statements), these mortgage notes are included in “Other liabilities related to properties sold or held for sale” on the consolidated balance sheets.

NOTE 5: UNSECURED LINES OF CREDIT PAYABLE

As of September 30, 2011, we maintained a $75.0 million unsecured line of credit (“Credit Facility No. 1”) maturing in June 2012 and a $400.0 million unsecured line of credit (“Credit Facility No. 2”) maturing in July 2014.

The amounts of these lines of credit unused and available at September 30, 2011 are as follows (in millions):

|  | Credit Facility No. 1 |  |  | Credit Facility No. 2 |
Committed capacity |  | $ | 75.0 |  |  | $ | 400.0 |
Borrowings outstanding |  |  | (74.0 | ) |  |  | (119.0 | )
Letters of credit issued |  |  | (0.8 | ) |  |  | (0.9 | )
Unused and available |  | $ | 0.2 |  |  | $ | 280.1 |

We executed borrowings and repayments on the unsecured lines of credit during the 2011 Quarter as follows (in millions):

|  | Credit Facility No. 1 |  |  | Credit Facility No. 2 |
Balance at June 30, 2011 |  | $ | 74.0 |  |  | $ | 171.0 |

Repayments |  |  | — |  |  |  | (110.0 | )
Balance at September 30, 2011 |  | $ | 74.0 |  |  | $ | 119.0 |

We made borrowings during the 2011 Quarter to partially fund the acquisitions of Olney Village Center and John Marshall II, to pay off the Shady Grove Medical Center mortgage note and for general corporate purposes. We made a repayment during the 2011 Quarter using proceeds from the first phase of the sale of the Industrial Portfolio.

NOTE 6: NOTES PAYABLE

We repaid the remaining $2.7 million of our 3.875% convertible notes without penalty in September 2011 using proceeds from the sale of the Industrial Portfolio.

NOTE 7: DERIVATIVE INSTRUMENTS

In May 2009, we entered into a forward interest rate swap with a notional amount of $100.0 million that qualifies as a cash flow hedge. We enter into interest rate swaps to manage our exposure to variable rate interest risk. We do not purchase derivatives for speculation. We record our cash flow hedges at fair value in accordance with GAAP, based on various discounted cash flow methodologies and observable inputs. We record the effective portion of changes in fair value of cash flow hedges in other comprehensive income. This change in fair value of cash flow hedges is the only activity in other comprehensive income (loss) during the periods presented in our consolidated financial statements. We record the ineffective portion of changes in fair value of cash flow hedges in earnings in the period affected. We assess the effectiveness of our cash flow hedges both at inception and on an ongoing basis. We deemed the hedges to be effective for the 2011 and 2010 Quarters and Periods, as applicable.

The fair value and balance sheet locations of the interest rate swaps as of September 30, 2011 and December 31, 2010 are as follows (in millions):

|  | September 30, 2011 |  |  | December 31, 2010 |
|  | Fair Value |  |  | Fair Value |
Accounts payable and other liabilities |  | $ | 0.2 |  |  | $ | 1.5 |

The interest rate swap has been effective since inception. The gain or loss on the effective swaps is recognized in other comprehensive income, as follows (in millions):

|  | Quarter Ended September 30, |  |  | Period Ended September 30, |
|  | 2011 |  |  | 2010 |  |  | 2011 |  |  | 2010 |

##### Table of Contents

Derivative instruments expose us to credit risk in the event of non-performance by the counterparty under the terms of the interest rate hedge agreement. We believe that we minimize our credit risk on these transactions by dealing with major, creditworthy financial institutions. As part of our on-going control procedures, we monitor the credit ratings of counterparties and our exposure to any single entity, thus minimizing our credit risk concentration.

NOTE 8: STOCK BASED COMPENSATION

WRIT maintains short-term and long-term incentive plans that allow for stock-based awards to officers and non-officer employees. Stock based awards are provided to officers and non-officer employees, as well as trustees, under the Washington Real Estate Investment Trust 2007 Omnibus Long-Term Incentive Plan which allows for awards in the form of restricted shares, restricted share units, options, and other awards up to an aggregate of 2,000,000 shares over the ten year period in which the plan will be in effect. Restricted share units are converted into shares of our stock upon full vesting through the issuance of new shares.

WRIT’s Compensation Committee conducted an extensive review of our executive compensation philosophy and a fundamental redesign of our short-term and long-term incentive plans for our officers, resulting in new short-term incentive (“New STIP”) and new long-term incentive (“New LTIP”) plans, which were approved by the Compensation Committee and Board on February 17, 2011 and were effective as of January 1, 2011.

New STIP

Under the New STIP, officers will earn awards, payable 50% in cash and 50% in restricted shares, based on a percentage of salary and achieving various performance conditions within a one-year performance period (except for 15% of such restricted share awards which will be exclusively service-based).

With respect to the 50% of the New STIP award payable in restricted shares, (i) the restricted shares subject to performance conditions will vest over a three-year period commencing on the January 1 following the end of the one-year performance period, and (ii) the restricted shares subject only to a service condition will vest over a three year period commencing at the beginning of the one-year performance period.

With respect to the 50% of the award payable in cash, the officer may elect to defer up to 80% of the cash portion pursuant to WRIT’s deferred compensation plan for officers. If the officer makes such election, the cash will be converted to restricted share units and WRIT will match 25% of deferred amounts in restricted share units.

For the service based awards we recognize compensation expense based on the grant date fair value, ratably over a three-year period commencing with the start of the performance period. With respect to the restricted shares subject to performance conditions expected to be awarded under the New STIP at the end of the one-year performance period, we recognize compensation expense based on the current fair market value of the probable award until the performance condition has been met, according to a graded vesting schedule over a four-year period commencing with the date the performance targets were established. Approximately 20% of the restricted shares subject to performance conditions awarded by the Compensation Committee at the end of the one-year performance period are based on subjective strategic acquisition and disposition goal criteria, for which we recognize compensation expense when the grant date occurs at the end of the one-year period.

New LTIP

Under the New LTIP, officers will earn awards, payable 50% in unrestricted shares and 50% in restricted shares, based on a percentage of salary and achieving various market and performance conditions during a defined three-year performance period (e.g., commencing on January 1, 2011 and concluding on December 31, 2013).

New LTIP performance will be evaluated on objective and subjective performance goals and weightings. Of the officers’ total potential award, 40% is subject to market conditions based on absolute total shareholder return (“TSR”) and relative TSR. The remaining 60% of the award is based primarily on strategic plan fulfillment, evaluated and determined by the Compensation Committee in its discretion at the end of the three-year performance period.

13

##### Table of Contents

The unrestricted shares vest immediately at the end of the three-year performance period, and the restricted shares vest over a one-year period commencing on the January 1 following the end of the three-year performance period.

With respect to the 40% of the New LTIP subject to market conditions we recognize compensation expense ratably (over three years for the 50% unrestricted shares and over four years for the 50% restricted shares) based on the grant date fair value, as determined using a Monte Carlo simulation, and regardless of whether the market conditions are achieved and the awards ultimately vest. With respect to the 60% subjective portion of the New LTIP, we will recognize compensation expense for the 50% unrestricted shares when the grant date has occurred at the end of the three year performance period. We will recognize compensation expense for the 50% restricted shares over the one-year vesting period commencing upon the grant date at the end of the three-year performance period.

Modification of Prior LTIP Awards

In connection with the adoption of the New STIP and the New LTIP, the prior LTIP for officers was amended such that awards subject to performance conditions through 2012 under the prior LTIP were converted when the new plans were adopted into 154,400 restricted share units as of February 17, 2011. Such restricted share units will vest consistent with the periods in which they otherwise would have vested under the terms of the prior LTIP (i.e., either December 31, 2011 or December 31, 2012). We accounted for the amendment of these awards as a modification.

Prior LTIP

Other non-officer members of management continue to earn restricted share units under the prior LTIP based upon various percentages of their salaries that vest ratably over five years from the grant date based upon continued employment. We recognize compensation expense for these awards according to a graded vesting schedule over six years from the date the performance target was established.

Trustee Awards

We continue to award trustees share based compensation on an annual basis in the form of restricted shares which vest immediately and are restricted from sale for the period of the trustees’ service.

Total Compensation Expense

Total compensation expense recognized in the consolidated financial statements for all share based awards, including share grants, restricted share units and performance share units, in the 2011 and 2010 Quarters was (in thousands):

|  | Quarter Ended September 30, |  |  | Period Ended September 30, |
|  | 2011 |  |  | 2010 |  |  | 2011 |  |  | 2010 |
Stock Based Compensation Expense |  | $ | 1.4 |  |  | $ | 1.3 |  |  | $ | 4.1 |  |  | $ | 4.3 |

Restricted and Unrestricted Shares

The total fair value of prior period shares vested during the 2011 Period is $28,800; no shares vested during the 2011 Quarter. As of September 30, 2011, there are no remaining unvested restricted shares granted under prior LTIPs.

During the 2011 Period, 10,822 restricted shares, with a total fair value of $0.3 million, were granted under the New STIP to officers for the portion of the New STIP award subject only to service conditions. We value these awards based on the fair market value on the date of grant. As of September 30, 2011, the total unamortized value of these unvested share awards was $265,600, which we expect to recognize as compensation expense over a weighted average period of 27 months. As of September 30, 2011, the future expected expense related to restricted shares with performance conditions, estimated based on the probable number of restricted shares expected to be awarded under the New STIP, totaled $0.6 million, which we expect to recognize as compensation cost over a weighted average period of 28 months.

Restricted and Unrestricted Shares with Market Conditions

Stock based awards with market conditions under the New LTIP were granted in February 2011 with fair market values, as determined using a Monte Carlo simulation, as follows (in thousands):

|  | Grant Date Fair Value |
|  | Restricted |  |  | Unrestricted |
Relative TSR |  | $ | 1,066 |  |  | $ | 1,066 |
Absolute TSR |  | $ | 365 |  |  | $ | 365 |

14

##### Table of Contents

The unamortized value of these awards with market conditions as of September 30, 2011 was as follows (in thousands):

|  | Unamortized Value at September 30, 2011 |
|  | Restricted |  |  | Unrestricted |
Relative TSR |  | $ | 894 |  |  | $ | 834 |
Absolute TSR |  | $ | 306 |  |  | $ | 286 |

We expect to recognize these unamortized values as compensation expense over a weighted average life of 39 months for the restricted shares and 27 months for the unrestricted shares.

Restricted Share Units

Restricted share units granted to officers and non-officers in prior periods continue to vest in the current year. The total fair value of restricted share units vested during the 2011 Quarter is zero and during the Period is $247,100. In connection with the adoption of new executive incentive plans, on February 17, 2011, all performance share units were converted into a fixed number of restricted share units. The total number of restricted share units awarded was 89,000 and 65,400, which vest on December 31, 2011 and December 31, 2012, respectively. The value of unvested restricted share units at September 30, 2011 was $4.1 million, which we expect to recognize as compensation cost over a weighted average period of 27 months. As of September 30, 2011, the future expected expense related to restricted share units with performance conditions expected to be awarded to non-officers in December 2011 is $0.8 million, which we expect to recognize as compensation cost over a weighted average period of 28 months.

Options

WRIT still has options outstanding from the 2001 Stock Option Plan and Stock Option Plan for Trustees. The 103,102 options outstanding at September 30, 2011, all of which are exercisable, have exercise prices between $24.85 and $33.09, with a weighted-average exercise price of $27.31 and a weighted average remaining contractual life of 1.6 years. The aggregate intrinsic value of outstanding exercisable shares at September 30, 2011 was $0.1 million. There were 42,883 options exercised in the 2011 Period, with an aggregate intrinsic value of $0.2 million.

NOTE 9: FAIR VALUE DISCLOSURES

Financial Assets and Liabilities Measured at Fair Value

For assets and liabilities measured at fair value on a recurring basis, quantitative disclosures about the fair value measurements are required to be disclosed separately for each major category of assets and liabilities, as follows:

Level 1: Quoted Prices in Active Markets for Identical Assets

Level 2: Significant Other Observable Inputs

Level 3: Significant Unobservable Inputs

The only assets or liabilities we had at September 30, 2011 and December 31, 2010 that are recorded at fair value on a recurring basis are the assets held in the Supplemental Executive Retirement Program (“SERP”) and the interest rate hedge contracts. We base the valuations related to these items on assumptions derived from significant other observable inputs and accordingly these valuations fall into Level 2 in the fair value hierarchy. The fair values of these assets and liabilities at September 30, 2011 and December 31, 2010 are as follows (in millions):

|  | September 30, 2011 |  |  | December 31, 2010 |
|  | Fair Value |  |  | Level 1 |  |  | Level 2 |  |  | Level 3 |  |  | Fair Value |  |  | Level 1 |  |  | Level 2 |  |  | Level 3 |
Assets: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Financial Assets and Liabilities Not Measured at Fair Value

The following disclosures of estimated fair value were determined by management using available market information and established valuation methodologies, including discounted cash flow. Many of these estimates involve significant judgment. The estimated fair value disclosed may not necessarily be indicative of the amounts we could realize on disposition of the financial instruments. The use of different market assumptions or estimation methodologies could have an effect on the estimated fair value amounts. In addition, fair value estimates are made at a point in time and thus, estimates of fair value subsequent to September 30, 2011 may differ significantly from the amounts presented.

Below is a summary of significant methodologies used in estimating fair values and a schedule of fair values at September 30, 2011.

Cash and Cash Equivalents

Cash and cash equivalents includes cash and commercial paper with original maturities of less than 90 days, which are valued at the carrying value, which approximates fair value due to the short maturity of these instruments.

Notes Receivable

The fair value of the notes is estimated based on quotes for debt with similar terms and characteristics or a discounted cash flow methodology using market discount rates if reliable quotes are not available.

Mortgage Notes Payable

Mortgage notes payable consist of instruments in which certain of our real estate assets are used for collateral. The fair value of the mortgage notes payable is estimated by discounting the contractual cash flows at a rate equal to the relevant treasury rates (with respect to the timing of each cash flow) plus credit spreads estimated through independent comparisons to real estate assets or loans with similar characteristics.

Lines of Credit Payable

Lines of credit payable consist of bank facilities which we use for various purposes including working capital, acquisition funding or capital improvements. The lines of credit advances are priced at a specified rate plus a spread. The carrying value of the lines of credit payable is estimated to be market value given the adjustable rate of these borrowings.

Notes Payable

The fair value of the notes payable is estimated by discounting the contractual cash flows at a rate equal to the relevant treasury rates (with respect to the timing of each cash flow) plus credit spreads derived using the relevant securities’ market prices.

NOTE 10: EARNINGS PER COMMON SHARE

We determine “Basic earnings per share” using the two-class method as our unvested restricted share awards have non-forfeitable rights to dividends, and are therefore considered participating securities. We compute basic earnings per share by dividing net income attributable to the controlling interest less the allocation of undistributed earnings to unvested restricted share awards by the weighted-average number of common shares outstanding for the period.

We also determine “Diluted earnings per share” under the two-class method with respect to the unvested restricted share awards. We further evaluate any other potentially dilutive securities at the end of the period and adjust the basic earnings per share calculation for the impact of those securities that are dilutive. Our diluted earnings per share calculation includes the dilutive impact of employee stock options based on the treasury stock method and our long-term incentive share units under the contingently issuable method. The diluted earnings per share calculation also considers our operating partnership units and 3.875% convertible notes under the if-converted method. The operating partnership units were anti-dilutive for the 2011 and 2010 Quarters and Periods and are not included in our earnings per share calculations. The 3.875% convertible notes, which were repaid in full during the 2011 Quarter, were anti-dilutive for the reporting periods during which they were outstanding.

NOTE 11: SEGMENT INFORMATION

We have five reportable segments: office, medical office, retail, multifamily and industrial/flex properties. Office buildings provide office space for various types of businesses and professions. Medical office buildings provide offices and facilities for a variety of medical services. Retail centers are typically neighborhood grocery store or drug store anchored retail centers. Multifamily properties provide rental housing for individuals and families throughout the Washington metropolitan area. Industrial/flex centers are used for flex-office, warehousing, services and distribution type facilities. The industrial/flex centers segment is classified as properties sold or held for sale and is presented as discontinued operations in the consolidated balance sheets and consolidated statements of income (see note 3 to the consolidate financial statements).

We evaluate performance based upon operating income from the combined properties in each segment. Our reportable operating segments are consolidations of similar properties. GAAP requires that segment disclosures present the measure(s) used by the chief operating decision maker for purposes of assessing segments’ performance. Net operating income is a key measurement of our segment profit and loss. Net operating income is defined as segment real estate rental revenue less segment real estate expenses.

General

Introductory Matters

We provide our Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) in addition to the accompanying consolidated financial statements and notes to assist readers in understanding our results of operations and financial condition. We organize the MD&A as follows:

| • |  | Overview. Discussion of our business, operating results, investment activity and capital requirements, and summary of our significant transactions to provide context for the remainder of MD&A.

| • |  | Results of Operations. Discussion of our financial results comparing the 2011 Quarter to the 2010 Quarter and the 2011 Period to the 2010 Period.

| • |  | Liquidity and Capital Resources. Discussion of our financial condition and analysis of changes in our capital structure and cash flows.

| • |  | Critical Accounting Policies and Estimates. Descriptions of accounting policies that reflect significant judgments and estimates used in the preparation of our consolidated financial statements.

When evaluating our financial condition and operating performance, we focus on the following financial and non-financial indicators:

| • |  | Net operating income (“NOI”), calculated as real estate rental revenue less real estate expenses excluding depreciation and amortization, interest expense and general and administrative expenses. NOI is a non-GAAP supplemental measure to net income.

| • |  | Funds From Operations (“FFO”), calculated as set forth below under the caption “Funds from Operations.” FFO is a non-GAAP supplemental measure to net income.

| • |  | Occupancy, calculated as occupied square footage as a percentage of total square footage as of the last day of that period.

21

##### Table of Contents

| • |  | Leased percentage, calculated as the percentage of physical net rentable area leased for our commercial segments and percentage of apartments leased for our multifamily segment.

| • |  | Rental rates.

| • |  | Leasing activity, including new leases, renewals and expirations.

For purposes of evaluating comparative operating performance, we categorize our properties as “same-store”, “non-same-store” or discontinued operations. A “same-store” property is one that was owned for the entirety of the periods being evaluated, is stabilized from an occupancy standpoint and is included in continuing operations. A “non-same-store” property is one that was acquired or placed into service during either of the periods being evaluated and is included in continuing operations. Results for properties sold or held for sale during any of the periods evaluated are classified as discontinued operations.

Overview

Business

Our revenues are derived primarily from the ownership and operation of income-producing properties in the greater Washington metro region. As of September 30, 2011, we owned a diversified portfolio of 74 properties, totaling approximately 9.6 million square feet of commercial space and 2,540 multifamily units, and land held for development. These 74 properties consisted of 26 office properties, 3 industrial/flex properties, 18 medical office properties, 16 retail centers and 11 multifamily properties.

Operating Results

Our results of operations were as follows (in thousands):

|  | 2011 Quarter |  |  | 2010 Quarter |  |  | $ Change |  |  | % Change |
Real estate rental revenue |  | $ | 71,931 |  |  | $ | 65,032 |  |  | $ | 6,899 |  |  |  | 10.6 | %
NOI (1) |  | $ | 47,861 |  |  | $ | 43,120 |  |  | $ | 4,741 |  |  |  | 11.0 | %
Net income attributable to the controlling interests |  | $ | 63,008 |  |  | $ | 6,625 |  |  | $ | 56,383 |  |  |  | 851.1 | %
FFO (2) |  | $ | 30,756 |  |  | $ | 30,899 |  |  | $ | (143 | ) |  |  | (0.5 | )%

(1) | See page 30 of the MD&A for reconciliations of NOI to net income.

(2) | See page 46 of the MD&A for reconciliations of FFO to net income.

The increases in real estate rental revenue and NOI are due to acquisitions made during the past year. NOI for the same-store portfolio has been flat, with higher rental rates and lower operating expenses offset by lower occupancy. The lower occupancy reflects continued difficulties in leasing vacant commercial space. We believe that the federal debt-ceiling debate during the 2011 Quarter and general concerns about the national economy are factors in the difficult leasing environment.

The increase in net income attributable to the controlling interests is due to the gain on the first phase of the sale of our industrial segment (see following section) during the 2011 Quarter.

Investment and Sales Activity

We purchased two office properties and one retail property for an aggregate contract purchase price of $232.5 million during the 2011 Quarter. These transactions are consistent with our stated acquisition strategy of focusing on properties inside the Washington metro region’s Beltway, near major transportation nodes and in areas with strong employment drivers and superior growth demographics.

On August 5, 2011, we executed five separate contracts with the same buyer for the sale of our industrial segment and two office properties (the “Industrial Portfolio”) for an aggregate sales price of $350.0 million. On September 2, 2011, we closed on the first three contracts, selling 15 industrial and two office properties for a $56.6 million gain on sale of real estate. Subsequent to the end of the 2011 Quarter, on October 3, 2011, we closed on the fourth contract for the sale of Northern Virginia Industrial Park II. On November 1, 2011, we closed on the final contract for 6100 Columbia Park Road and Dulles Business Park.

Capital Requirements

As of September 30, 2011, our unsecured lines of credit had $193.0 million in borrowings outstanding and $1.7 million in letters of credit issued, leaving a remaining borrowing capacity of $280.3 million.

We repaid without penalty during the 2011 Quarter the remaining $9.1 million on the mortgage note secured by Shady Grove Medical Village II and the remaining $2.7 million of our 3.875% convertible notes. Subsequent to the end of the 2011 Quarter,

##### Table of Contents

we prepaid the remaining $17.9 million principal balance on the mortgage notes secured by Dulles Business Park. We incurred $1.0 million in prepayment penalties, which were partially offset by an $875,000 increase in the sales price for the secured properties. We do not have any other notes that mature during the remainder of 2011.

##### Table of Contents

Significant Transactions

We summarize below our significant transactions during the 2011 and 2010 Periods:

2011 Period

We closed on the final two sale contracts subsequent to the end of the 2011 Quarter, on October 3, 2011 and November 1, 2011.

| • |  | The disposition of Dulles Station, Phase I, a 180,000 square foot office building in Herndon, Virginia for a contract sales price of $58.8 million.

| • |  | The execution of an unsecured credit facility agreement that replaced and expanded Credit Facility No. 2 from $262.0 million to $400.0 million, with an accordion feature that allows us to increase the facility to $600.0 million, subject to additional lender commitments. The new unsecured line of credit matures on July 1, 2014 with a one-year extension option and currently bears an interest rate at LIBOR plus a margin of 122.5 basis points.

| • |  | The execution of new leases for 0.8 million square feet of commercial space (excluding first generation leases at recently-built properties and properties sold or held for sale), with an average rental rate increase of 9.5% over expiring leases.

2010 Period

| • |  | The disposition of the Parklawn Portfolio, consisting of three office properties and one industrial property, for a contract sales price of $23.4 million and a gain on sale of $7.9 million.

| • |  | The repurchase of $1.2 million of our 3.875% convertible notes at 99.3% of par, resulting in a net loss on extinguishment of debt of $41,600.

| • |  | The issuance of 2.3 million common shares at a weighted average price of $29.60 under our sales agency financing agreement, raising $67.1 million in net proceeds.

| • |  | The execution of new leases for 0.8 million square feet of commercial space (excluding first generation leases at recently-built properties and properties sold or held for sale), with an average rental rate increase of 12.6% over expiring leases.

Results of Operations

The discussion that follows is based on our consolidated results of operations for the 2011 and 2010 Quarters and Periods. The ability to compare one period to another may be significantly affected by acquisitions completed and dispositions made during those periods. To provide more insight into our operating results, we divide our discussion into two main sections:

| • |  | Consolidated Results of Operations: Overview analysis of results on a consolidated basis.

| • |  | Net Operating Income (“NOI”): Detailed analysis of same-store and non-same-store NOI results by segment.

Recoveries from Tenants: Recoveries from tenants increased by $0.7 million in the 2011 Quarter primarily due to acquisitions.

Recoveries from tenants increased by $0.4 million in the 2011 Period due to acquisitions ($1.5 million), partially offset by lower reimbursements for real estate taxes ($1.1 million) at same-store properties caused by lower property tax assessments.

Provisions for Doubtful Accounts: Provisions for doubtful accounts increased by $0.3 million in the 2011 Quarter due to higher provisions in the retail ($0.2 million) and office ($0.1 million) segments.

Provisions for doubtful accounts increased by $0.2 million in the 2011 Period due primarily to higher provisions in the retail ($0.7 million) and medical office ($0.2 million) segments, partially offset by lower provisions in the office segment ($0.6 million).

Lease Termination Fees: Lease termination fees increased by $0.1 million in the 2011 Quarter, primarily in the retail segment.

Parking and Other Tenant Charges: Parking and other tenant charges from acquisitions caused the $0.1 million increase in the 2011 Quarter.

Parking income from acquisitions ($0.4 million) and higher parking income ($0.2 million) and antenna rents ($0.1 million) from same-store properties caused the $0.7 million increase in parking and other tenant charges in the 2011 Period.

Property Operating Expenses: Property operating expenses include utilities, repairs and maintenance, property administration and management, operating services, common area maintenance, property insurance, bad debt and other operating expenses.

Property operating expenses from acquisitions ($1.2 million) and higher property administration and management ($0.4 million) and repairs and maintenance ($0.4 million) expenses at same-store properties primarily caused the $2.2 million increase in the 2011 Quarter.

Property operating expenses from acquisitions ($3.8 million) and higher repairs and maintenance ($0.5 million), administrative ($0.3 million) and legal ($0.1 million) costs at same-store properties primarily caused the $4.9 million increase in the 2011 Period.

Real Estate Taxes: Lower assessments on same-store properties ($0.8 million), offset by real estate taxes on acquisitions ($0.7 million) caused the $0.1 million decrease in the 2011 Quarter.

Real estate taxes on acquisitions ($2.1 million) offset by lower assessments on same-store properties ($1.6 million) caused the $0.6 million increase in the 2011 Period.

Depreciation and Amortization: Depreciation and amortization expense from acquisitions caused the $3.3 million increase in the 2011 Quarter.

Depreciation and amortization expense from acquisitions ($9.9 million), partially offset by lower depreciation and amortization expense at same-store properties ($1.6 million), caused the $8.3 million increase in the 2011 Period.

The lower depreciation and amortization expense at same-store properties is primarily due to lower amortization of intangible assets associated with the acquisition of properties.

Discontinued Operations

We dispose of assets (sometimes using tax-deferred exchanges) that no longer meet our long-term strategy or return objectives and where market conditions for sale are favorable. The proceeds from the sales may be reinvested into other properties, used to fund development operations or to support other corporate needs, or distributed to our shareholders.

Properties we sold during 2011 and 2010 are as follows:

Net Operating Income

NOI is the primary performance measure we use to assess the results of our operations at the property level. We believe that NOI is useful as a performance measure because, when compared across periods, NOI reflects the impact on operations of trends in occupancy rates, rental rates and operating costs on an unleveraged basis, providing perspective not immediately apparent from net income. NOI excludes certain components from net income in order to provide results more closely related to a property’s results of operations. For example, interest expense is not necessarily linked to the operating performance of a real estate asset. In addition, depreciation and amortization, because of historical cost accounting and useful life estimates, may distort operating performance at the property level. As a result of the foregoing, we provide NOI as a supplement to net income calculated in accordance with GAAP. NOI does not represent net income calculated in accordance with GAAP. As such, it should not be considered an alternative to net income as an indication of our operating performance. A reconciliation of NOI to net income follows.

(2) | Discontinued operations include gain on disposals and income from operations for:

2011 held for sale and sold – Dulles Station, Phase I and the Industrial Portfolio

2010 dispositions – Parklawn Plaza, Lexington Building, Saratoga Building, Charleston Business Center, the Ridges,

Ammendale I&II and Amvax

Real estate rental revenue from same-store properties increased by $0.5 million in the 2011 Quarter primarily due to higher rental rates ($1.2 million), partially offset by lower occupancy ($0.6 million).

Real estate expenses from same-store properties increased by $0.2 million in the 2011 Quarter as higher operating expenses ($1.0 million) were offset by lower real estate taxes ($0.8 million).

The decrease in same-store occupancy was the result of difficulties in leasing vacant space across all segments. The increase in non-same-store occupancy reflects the acquisitions made during the 2011 Period and 2010. Lansdowne Medical Office Building, which was vacant upon acquisition in 2009, was 32.0% leased as of the end of the 2011 Quarter. During the 2011 Quarter, 56.9% of the commercial square footage expiring was renewed as compared to 38.2% in the 2010 Quarter, excluding properties sold or classified as held for sale. During the 2011 Quarter, we executed new leases (excluding first generation leases at recently-built properties) for 241,900 commercial square feet at an average rental rate of $33.71 per square foot, an increase of 11.7%, with average tenant improvements and leasing costs of $24.44 per square foot.

Real estate expenses from same-store properties decreased by $0.7 million due to lower real estate taxes ($0.9 million) partially offset by higher repairs and maintenance costs ($0.2 million).

The decrease in same-store occupancy was primarily due to lower occupancy at 2000 M Street and West Gude Drive, partially offset by higher occupancy at One Central Plaza.

2009 acquisition – Lansdowne Medical Office Building

Real estate rental revenue from same-store properties increased by $0.2 million in 2011 Quarter due to higher rental rates ($0.3 million) and higher reimbursements for operating expenses ($0.1 million), partially offset by lower occupancy ($0.2 million).

Real estate expenses from same-store properties slightly increased in the 2011 Quarter.

The decrease in same-store occupancy was driven by lower occupancy at Woodholme Medical Center, 9707 Medical Center Drive and 8301 Arlington Boulevard. The increase in non-same-store occupancy to 27.0% in the 2011 Quarter reflects the continued lease-up of Lansdowne Medical Office Building, which was newly-constructed and vacant when purchased during the fourth quarter of 2009. During the 2011 Quarter, 72.1% of the square footage that expired was renewed compared to 90.2% in the 2010 Quarter. During the 2011 Quarter, we executed new leases (excluding first generation leases) for 29,100 square feet of medical office space at an average rental rate of $37.76, an increase of 9.0%, with average tenant improvements and leasing costs of $10.96 per square foot.

(1) | Non-same-store properties include:

2011 acquisition – Olney Village Center

2010 acquisition – Gateway Overlook

Real estate rental revenue from same-store properties increased by $0.3 million in the 2011 Quarter due to higher rental rates ($0.1 million), higher reimbursements for common area maintenance ($0.2 million) and higher lease termination fees ($0.1 million), partially offset by higher reserves for uncollectible revenue ($0.2 million).

Real estate expenses from same-store properties increased by $0.5 million in the 2011 Quarter primarily due to higher utilities ($0.1 million), common area maintenance ($0.1 million) and legal ($0.1 million) costs and real estate taxes ($0.1 million).

The decrease in same-store occupancy was driven by lower occupancy at the Centre at Hagerstown, partially offset by higher occupancy at Montgomery Village Center. The non-same-store occupancy of 94.7% reflects the acquisitions of Olney Village Center and Gateway Overlook. During the 2011 Quarter, 15.9% of the square footage that expired was renewed compared to 33.8% in the 2010 Quarter. During the 2011 Quarter, we executed new leases for 59,900 square feet of retail space at an average rental rate of $18.56, an increase of 31.3%, with average tenant improvements and leasing costs of $32.19 per square foot.

Liquidity and Capital Resources

Capital Structure

During 2011, we expect that we will have the following capital requirements. There can be no assurance that our capital requirements will not be materially higher or lower than these expectations.

| • |  | Funding dividends on our common shares and noncontrolling interest distributions to third party unit holders;

| • |  | All remaining 2011 maturities on our mortgage notes payable and unsecured notes payable have been paid;

| • |  | Approximately $35.0 - $45.0 million to invest in our existing portfolio of operating assets, including approximately $20.0 - $25.0 million to fund tenant-related capital requirements and leasing commissions;

| • |  | Approximately $1.0 million to fund first generation tenant-related capital requirements and leasing commissions;

| • |  | Approximately $25.0 - $30.0 million to invest in our development projects; and

| • |  | Approximately $283.1 million, net of assumed mortgages, to fund our known property acquisitions, all of which closed in the 2011 Period.

Debt Financing

Our total debt at September 30, 2011 and December 31, 2010 is summarized as follows (in thousands):

|  | September 30, 2011 |  |  | December 31, 2010 |
Fixed rate mortgages |  | $ | 428,909 |  |  | $ | 361,860 |
Unsecured credit facilities |  |  | 193,000 |  |  |  | 100,000 |
Unsecured notes payable |  |  | 657,378 |  |  |  | 753,587 |
|  | $ | 1,279,287 |  |  | $ | 1,215,447 |

Mortgage Debt

At September 30, 2011, our $428.9 million in fixed rate mortgages, which includes a net $4.4 million in unamortized discounts due to fair value adjustments, bore an effective weighted average fair value interest rate of 5.9% and had a weighted average maturity of 4.7 years. We may either initiate secured mortgage debt or assume mortgage debt from time-to-time in conjunction with property acquisitions.

Unsecured Credit Facilities

Our primary external source of liquidity is our two revolving credit facilities.

Credit Facility No. 1 is a $75.0 million unsecured credit facility set to expire in June 2012. We had $74.0 million outstanding and $0.8 million in letters of credit issued as of September 30, 2011, related to Credit Facility No. 1. Borrowings under the facility bear interest at our option of LIBOR plus a spread based on the credit rating on our publicly issued debt or the higher of SunTrust Bank’s prime rate and the Federal Funds Rate in effect plus 0.5%. The interest rate spread is currently 42.5 basis points. All outstanding advances are due and payable upon maturity in June 2012. Interest only payments are due and payable generally on a monthly basis. In addition, we pay a facility fee based on the credit rating of our publicly issued debt which currently equals 0.15% per annum of the $75.0 million committed capacity, without regard to usage. Rates and fees may be adjusted up or down based on changes in our senior unsecured credit ratings.

Credit Facility No. 2 is a $400.0 million unsecured credit facility expiring in July 2014. We had $119.0 million outstanding and $0.9 million in letters of credit issued as of September 30, 2011, related to Credit Facility No. 2. Advances under this agreement bear interest at our option of LIBOR plus a spread based on the credit rating of our publicly issued debt or the higher of Wells Fargo Bank’s prime rate and the Federal Funds Rate in effect on that day plus 0.5%. The interest rate spread is currently 122.5 basis points. Interest only payments are due and payable generally on a monthly basis. Credit Facility No. 2 requires us to pay the lender a facility fee on the total commitment of 0.225% per annum. These fees are payable quarterly. All outstanding advances are due and payable upon maturity in July 2014 with a one-year extension option.

##### Table of Contents

An interest rate swap effectively fixes the interest rate on $100.0 million of the outstanding balance on our unsecured lines of credit at 2.845% through the interest rate swap’s maturity date of November 1, 2011.

Our unsecured credit facilities contain financial and other covenants with which we must comply. Some of these covenants include:

| • |  | A minimum tangible net worth;

| • |  | A maximum ratio of total liabilities to gross asset value, calculated using an estimate of fair market value of our assets;

| • |  | A maximum ratio of secured indebtedness to gross asset value, calculated using an estimate of fair market value of our assets;

| • |  | A minimum ratio of annual EBITDA (earnings before interest, taxes, depreciation and amortization) to fixed charges, including interest expense;

| • |  | A minimum ratio of unencumbered asset value, calculated using a fair value of our assets, to unsecured indebtedness;

| • |  | A minimum ratio of net operating income from our unencumbered properties to unsecured interest expense; and

| • |  | A maximum ratio of permitted investments to gross asset value, calculated using an estimate of fair market value of our assets.

Failure to comply with any of the covenants under our unsecured credit facilities or other debt instruments could result in a default under one or more of our debt instruments. This could cause our lenders to accelerate the timing of payments and would therefore have a material adverse effect on our business, operations, financial condition and liquidity. In addition, our ability to draw on our unsecured credit facilities or incur other unsecured debt in the future could be restricted by the loan covenants. As of September 30, 2011, we were in compliance with our loan covenants.

There is a possibility that in the near term we may rely to a greater extent upon our unsecured credit facilities and potentially maintain balances on our unsecured credit facilities for longer periods than has been our historical practice. To the extent that we maintain larger balances on our unsecured credit facilities or maintain balances on our unsecured credit facilities for longer periods, adverse fluctuations in interest rates could have a material adverse effect on earnings.

Unsecured Notes

We generally issue unsecured notes to fund our real estate assets long-term. In issuing future unsecured notes, we generally seek to ladder the maturities of our debt to mitigate exposure to interest rate risk in any particular future year.

Our unsecured notes have maturities ranging from May 2012 through February 2028, as follows (in thousands):

|  | September 30, 2011 |
|  | Note Principal |
5.05% notes due 2012 |  | $ | 50,000 |
5.125% notes due 2013 |  |  | 60,000 |
5.25% notes due 2014 |  |  | 100,000 |
5.35% notes due 2015 |  |  | 150,000 |
4.95% notes due 2020 |  |  | 250,000 |
7.25% notes due 2028 |  |  | 50,000 |
|  | $ | 660,000 |

Our unsecured notes contain covenants with which we must comply. These include:

| • |  | Limits on our total indebtedness;

| • |  | Limits on our secured indebtedness;

| • |  | Limits on our required debt service payments; and

| • |  | Maintenance of a minimum level of unencumbered assets.

Failure to comply with any of the covenants under our unsecured notes could result in a default under one or more of our debt instruments. This could cause our debt holders to accelerate the timing of payments and would therefore have a material adverse effect on our business, operations, financial condition and liquidity. As of September 30, 2011, we were in compliance with our unsecured notes covenants.

We may from time to time seek to repurchase and cancel our outstanding notes through open market purchases, privately negotiated transactions or otherwise. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

Common Equity

We have authorized for issuance 100.0 million common shares, of which 66.1 million shares were outstanding at September 30, 2011.

We have a dividend reinvestment program, whereby shareholders may use their dividends and optional cash payments to purchase common shares. The common shares sold under this program may either be common shares issued by us or common shares purchased in the open market. We use net proceeds under this program for general corporate purposes. For the 2011 Period, we issued 125,484 common shares at a weighted average price of $30.71 per share, raising $3.8 million in net proceeds.

Dividends

We pay dividends quarterly. The maintenance of these dividends is subject to various factors, including the discretion of our Board of Trustees, our results of operations, the ability to pay dividends under Maryland law, the availability of cash to make the necessary dividend payments and the effect of REIT distribution requirements, which require at least 90% of our taxable income to be distributed to shareholders.

The table below details our dividend and distribution payments for the 2011 and 2010 Quarters and Periods (in thousands).

Dividends paid for the 2011 Quarter and Period as compared to the 2010 Quarter and Period increased due primarily to the issuance of 5.6 million common shares under our sales agency financing agreement during 2010.

Cash flows from operations are an important factor in our ability to sustain our dividend at its current rate. If our cash flows from operations were to decline significantly, we may have to borrow on our lines of credit to sustain the dividend rate or reduce our dividend.

Historical Cash Flows

Consolidated cash flow information is summarized as follows (in millions):

|  | Period Ended September 30, |
|  |  |  |  |  |  |  | Change |
|  | 2011 |  |  | 2010 |  |  | $ |  |  | % |
Net cash provided by (used in) operating activities |  | $ | 86.4 |  |  | $ | 83.5 |  |  | $ | 2.9 |  |  |  | 3.5 | %
Net cash provided by (used in) investing activities |  | $ | (23.2 | ) |  | $ | (61.8 | ) |  | $ | 38.6 |  |  |  | (62.5 | )%
Net cash provided by (used in) financing activities |  | $ | (101.2 | ) |  | $ | 229.5 |  |  | $ | (330.7 | ) |  |  | (144.1 | )%

Our operating activities generated $86.4 million of net cash in the 2011 Period, an increase from $83.5 million in the 2010 Period that is primarily attributable the acquisitions made during 2011 and 2010, partially offset by dispositions and acquisition costs.

Our investing activities used net cash of $23.2 million in the 2011 Period compared to $61.8 million in the 2010 Period. The decrease in cash used by investing activities is primarily due proceeds from the first phase of the sale of the Industrial Portfolio, partially offset by a higher volume of acquisition activity during the 2011 Period.

Our financing activities used net cash of $101.2 million in the 2011 Period as compared to net cash provided of $229.5 million in the 2010 Period. The increase in cash used by financing activities is primarily due to the repayment of notes that matured during the 2011 Period, as well as proceeds from equity offerings during the 2010 Period.

Ratios of Earnings to Fixed Charges and Debt Service Coverage

The following table sets forth our ratios of earnings to fixed charges and debt service coverage for the periods shown:

|  | Quarter Ended September 30, |  |  | Period Ended September 30, |
|  | 2011 |  |  | 2010 |  |  | 2011 |  |  | 2010 |
Earnings to fixed charges |  |  | 1.1x |  |  |  | 1.2x |  |  |  | 1.2x |  |  |  | 1.1x |
Debt service coverage |  |  | 2.7x |  |  |  | 2.7x |  |  |  | 2.7x |  |  |  | 2.6x |

We computed the ratio of earnings to fixed charges by dividing earnings by fixed charges. For this purpose, earnings consist of income from continuing operations attributable to the controlling interests plus fixed charges, less capitalized interest. Fixed charges consist of interest expense, including amortized costs of debt issuance, and interest costs capitalized.

We computed the debt service coverage ratio by dividing Adjusted EBITDA (which is earnings before interest expense, taxes, depreciation, amortization, real estate impairment, gain on sale of real estate, gain/loss from the extinguishment of debt and gain/loss on non-disposal activities) by interest expense and principal amortization. We believe that Adjusted EBITDA is appropriate for use in our debt service coverage ratio because it provides an estimate of the cash available to pay down long term debt. Adjusted EBITDA does not represent net income calculated in accordance with GAAP. As such, it should not be considered an alternative to net income as an indication of our operating performance. A reconciliation of Adjusted EBITDA to net income attributable to the controlling interests is in Exhibit 12 – Computation of Ratios.

Funds From Operations

FFO is a widely used measure of operating performance for real estate companies. We provide FFO as a supplemental measure to net income calculated in accordance with GAAP. Although FFO is a widely used measure of operating performance for REITs, FFO does not represent net income calculated in accordance with GAAP. As such, it should not be considered an alternative to net income as an indication of our operating performance. In addition, FFO does not represent cash generated from operating activities in accordance with GAAP, nor does it represent cash available to pay distributions and should not be considered as an alternative to cash flow from operating activities, determined in accordance with GAAP, as a measure of our liquidity. The National Association of Real Estate Investment Trusts, Inc. (“NAREIT”) defines FFO (April, 2002 White Paper) as net income (computed in accordance with GAAP) excluding gains (or losses) associated with sales of property plus real estate depreciation and amortization. We consider FFO to be a standard supplemental measure for REITs because it facilitates an understanding of the operating performance of our properties without giving effect to real estate depreciation and amortization, which historically assumes that the value of real estate assets diminishes predictably over time. Since real estate values have instead historically risen or fallen with market conditions, we believe that FFO more accurately provides investors an indication of our ability to incur and service debt, make capital expenditures and fund other needs. Our FFO may not be comparable to FFO reported by other REITs. These other REITs may not define the term in accordance with the current NAREIT definition or may interpret the current NAREIT definition differently.

Critical Accounting Policies and Estimates

We base the discussion and analysis of our financial condition and results of operations upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. We discuss the most critical estimates in our Annual Report on Form 10-K for the year ended December 31, 2010 filed with the Securities and Exchange Commission on February 25, 2011.

ITEM 3: QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

The principal material financial market risk to which we are exposed is interest-rate risk. Our exposure to market risk for changes in interest rates relates primarily to refinancing long-term fixed rate obligations, the opportunity cost of fixed rate obligations in a falling interest rate environment and our variable rate lines of credit. We primarily enter into debt obligations to support general corporate purposes including acquisition of real estate properties, capital improvements and working capital needs.

As the majority of our outstanding debt is long-term, fixed rate debt, our interest rate risk has not changed significantly from what was disclosed in our 2010 Annual Report on Form 10-K. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources – Debt Financing.”

ITEM 4: CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Securities Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer, Chief Financial Officer and Executive Vice President of Accounting, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer, Chief Financial Officer and Executive Vice President of Accounting, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based on the foregoing, our Chief Executive Officer, Chief Financial Officer and Executive Vice President of Accounting concluded that our disclosure controls and procedures were effective at the reasonable assurance level.

There have been no changes in WRIT’s internal control over financial reporting (as defined by Rule 13a-15(f)) that occurred during the period covered by the report that have materially affected, or are reasonably likely to materially affect, WRIT’s internal control over financial reporting.
