NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

JUNE 30, 2014

(UNAUDITED)

NOTE 1: NATURE OF BUSINESS

Washington Real Estate Investment Trust (“Washington REIT”), 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 operation of income-producing real estate properties in the greater Washington metro region. We own a diversified portfolio of office buildings, 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 Washington REIT 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. During the first quarter of 2014, we closed on Transactions III (for the sale of Woodburn Medical Park I and II) and IV (for the sale of Prosperity Medical Center I, II and III) of the Medical Office Portfolio sale for an aggregate contract sales price of $193.6 million . We have reinvested a portion of the Medical Office Portfolio sales proceeds in replacement properties through a deferred tax exchange.

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 (“TRSs”). Our TRSs are subject to corporate federal and state income tax on their taxable income at regular statutory rates or as calculated under the alternative minimum tax, as appropriate. There were no material income tax provisions or material net deferred income tax items for our TRSs for the three and six months ended June 30, 2014 and 2013 .

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, 2013 .

New Accounting Pronouncements

In April 2014, the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity , which changes the requirements for reporting discontinued operations. Specifically, under this ASU only those disposals of components of an entity that represent a strategic shift that has (or will have) a major effect on an entity’s operations and financial results will be reported as discontinued operations in the financial statements. The primary impact of this ASU is that we are no longer required to report the disposal of every operating property in discontinued operations. Adoption of this ASU is required for all disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after after December 15, 2014, and interim periods within those years. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. We early adopted this ASU effective for the first quarter of 2014.

In June 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , which creates a single source of revenue guidance. The new standard provides accounting guidance for all revenue arising from contracts with customers and affects all entities that enter into contracts to provide goods or services to their customers (unless the contracts are in the scope of other U.S. generally accepted accounting principles (“GAAP”) requirements, such as the leasing literature). The guidance also provides a model for the measurement and recognition of gains and losses on the sale of certain nonfinancial assets, such as property and equipment, including real estate. The new standard is effective for public entities for fiscal years beginning after December 15, 2016 and for interim periods therein. Early adoption is not permitted for public entities. We are currently evaluating the impact the new standard may have on Washington REIT.

Principles of Consolidation and Basis of Presentation

The accompanying unaudited consolidated financial statements include the consolidated accounts of Washington REIT, our majority-owned subsidiaries and entities in which Washington REIT has a controlling interest, including where Washington REIT has been determined to be a primary beneficiary of a variable interest entity (“VIE”). See note 3 for additional information on the

properties for which there is a noncontrolling interest. 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 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, 2013 .

Within these notes to the financial statements, we refer to the three months ended June 30, 2014 and June 30, 2013 as the “ 2014 Quarter” and the “ 2013 Quarter,” respectively, and the six months ended June 30, 2014 and June 30, 2013 as the “ 2014 Period” and the “ 2013 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 period amounts have been reclassified to conform to the current period presentation due to the reclassification of certain properties as discontinued operations (see note 3).

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 2014 acquisitions are as follows (amounts in thousands):

We record the acquired physical assets (land, building and tenant improvements), and in-place leases (absorption, tenant origination costs, leasing commissions, and net lease intangible assets/liabilities), and any other assets or liabilities at their fair values.

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

The weighted remaining average life for the 2014 acquisition components above, other than land and building, are 74 months for tenant origination costs, 57 months for leasing commissions/absorption costs, 75 months for net lease intangible assets and 85 months for net lease intangible liabilities.

The difference in the total contract purchase price of $256.5 million for the 2014 acquisitions and the acquisition cost per the consolidated statement of cash flows of $154.1 million is primarily due to the assumption of two mortgage notes secured by Yale West and The Army Navy Club Building for an aggregate $100.9 million and the payment of a $3.6 million deposit for Yale West in 2013, partially offset by a credit to the seller for building renovations at 1775 Eye Street, NW for $1.9 million .

The following unaudited pro-forma combined condensed statements of operations are for the 2014 and 2013 Quarters and Periods as if the above described acquisitions had occurred at the beginning of the period of acquisition and the same period in the year prior to 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 2014 and 2013 Quarters and Periods. The unaudited data presented is in thousands, except per share data.

Redevelopment

In the office segment, we have an active redevelopment project to renovate 7900 Westpark Drive. Our total investment in the renovation at 7900 Westpark Drive is expected to be $35.0 million . As of June 30, 2014 and December 31, 2013 , we had invested $15.2 million and $3.6 million , respectively, in the renovation. We anticipate completion during the first quarter of 2015 .

Variable Interest Entities

In June 2011, we executed a joint venture operating agreement with a real estate development company to develop The Maxwell, a mid-rise multifamily property at 650 North Glebe Road in Arlington, Virginia. We estimate the total cost of the project to be $49.9 million . During the first quarter of 2013, we secured third-party debt financing for approximately 70% of the project's cost. Washington REIT is the 90% owner of the joint venture and will have management and leasing responsibilities when the project is completed and stabilized (defined as 90% of the residential units leased). The real estate development company owns 10% of the joint venture and is responsible for the development and construction of the property. The joint venture currently expects to complete this development project during the fourth quarter of 2014 .

In November 2011, we executed a joint venture operating agreement with a real estate development company to develop a high-rise multifamily property at 1225 First Street (formerly 1219 First Street) in Alexandria, Virginia. We estimate the total cost of the project to be $95.3 million , with approximately 70% of the project financed with debt. Washington REIT is the 95% owner of the joint venture and will have management and leasing responsibilities if the project is completed and stabilized. The real estate development company owns 5% of the joint venture and is responsible for the development and construction of the property. In the first quarter of 2013, we decided to delay commencement of construction due to market conditions and concerns of oversupply. We continue to reassess this project on a periodic basis going forward.

We have determined that The Maxwell and 1225 First Street joint ventures are VIE's primarily based on the fact that the equity investment at risk is not sufficient to permit either entity to finance its activities without additional financial support. We expect that 70% of the total development costs for each project would be financed through debt. We have also determined that Washington REIT is the primary beneficiary of each VIE due to the fact that Washington REIT is providing 90% to 95% of the equity contributions and will manage each property after stabilization.

We include the joint venture land acquisitions on our consolidated balance sheets in properties under development or held for future development. As of June 30, 2014 and December 31, 2013 , the land and capitalized development costs are as follows (in thousands):

As of June 30, 2014 and December 31, 2013 , the accounts payable and accrued liabilities related to the joint ventures are as follows (in thousands):

On February 21, 2013 , Washington REIT, through its consolidated joint venture to develop The Maxwell, entered into a construction loan agreement with Citizens Bank for $33.0 million . The loan bears interest at LIBOR plus 2.15% , which decreases to LIBOR plus 2.0% upon completion of construction and the joint venture not being in default. The loan matures on February 21, 2016 , with two one year extension options exercisable by the joint venture, subject to fees and compliance with certain provisions in the loan agreement. As of June 30, 2014 and December 31, 2013 , the consolidated joint venture had $14.0 million and $7.3 million , respectively, outstanding on this construction loan agreement.

Discontinued Operations

We dispose of assets 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 (see "Discontinued Operations" in note 2 of the consolidated financial statements included in Washington REIT's Annual Report on Form 10-K for the year ended December 31, 2013 ). 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.

In September 2013 , we entered into four separate purchase and sale agreements to effectuate the sale of our entire medical office segment (including land held for development at 4661 Kenmore Avenue) and two office buildings (Woodholme Center and 6565 Arlington Boulevard) for an aggregate purchase price of $500.8 million . The sale was structured as four transactions. Transactions I and II closed in November 2013 and Transactions III and IV closed in January 2014.

The results of our medical office segment are summarized as follows (amounts in thousands, except per share data):

We sold the following properties in 2014 and 2013:

⁽²⁾ This property is classified as continuing operations in accordance with ASU No. 2014-08 (see note 2).

As of June 30, 2014 and December 31, 2013 , investment in real estate for properties sold or held for sale, all of which were in the medical office segment, was as follows (in thousands):

Income from operations of properties sold or held for sale for the three and six months ended June 30, 2014 and 2013 was as follows (in thousands):

Income from operations of properties sold or held for sale by property for the three and six months ended June 30, 2014 and 2013 was as follows (in thousands):

NOTE 4: MORTGAGE NOTES PAYABLE

In February 2014 , we assumed a $48.2 million mortgage note as partial consideration for the acquisition of Yale West. This mortgage note bears interest at 5.55% per annum. The fair value interest rate on this mortgage note is 3.75% based on quotes obtained for similar loans. We recorded the mortgage note at its estimated fair value of $54.0 million . Principal and interest are payable monthly until January 1, 2052 , at which time all unpaid principal and interest are payable in full. The loan may be prepaid, without penalty, on January 31, 2022 or thereafter on the last business day of the month until maturity, with thirty days prior written notice to the lender.

In March 2014 , we assumed a $52.7 million mortgage note as partial consideration for acquisition of The Army Navy Club Building. This mortgage note bears interest at 3.45% per annum. The fair value interest rate on this mortgage note is 3.18% based on quotes obtained for similar loans. We recorded the mortgage at its estimated fair value of $53.2 million . Principal and interest are payable monthly until May 1, 2017 , at which time all unpaid principal and interest are payable in full.

We had no borrowings and no repayments on the unsecured lines of credit during the 2014 Period.

NOTE 6: NOTES PAYABLE

We repaid without penalty the $100.0 million of our 5.25% unsecured notes on their due date of January 15, 2014 , using proceeds from the sale of the Medical Office Portfolio.

NOTE 7: STOCK BASED COMPENSATION

Washington REIT maintains short-term ("STIP") and long-term ("LTIP") 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.

During the 2014 Period, the Board of Trustees adopted a new STIP and new LTIP for executive officers. Regarding the new STIP, the changes from the prior STIP primarily removed the 15% service-only component of the award, maintaining an award payable 50% in cash and 50% in stock. The new LTIP is based entirely on total shareholder return during a defined three-year period. The LTIP was also converted from a single three-year plan structure to a “rolling” structure in which a new three-year plan is commenced each year. The vesting at the end of the performance period was modified to be 75% at the end of the performance period and 25% one year thereafter. In addition, during the transition period to the new LTIP, the Board of Trustees awarded similar transition awards with defined performance periods of one and two years and modified vesting to account for the transition.

Total Compensation Expense

Total compensation expense recognized in the consolidated financial statements for all outstanding share based awards was $1.4 million and $1.4 million for the 2014 and 2013 Quarters, respectively, and $2.5 million and $2.4 million for the 2014 and 2013 Periods, respectively.

Restricted Share Awards

The total fair values of restricted share awards vested was $0.7 million for the 2014 and 2013 Periods.

The total unvested restricted share awards at June 30, 2014 was 222,469 shares, which had a weighted average grant date fair value of $25.41 per share. As of June 30, 2014 , the total compensation cost related to unvested restricted share awards was $2.4 million , which we expect to recognize over a weighted average period of 18 months.

NOTE 8: FAIR VALUE DISCLOSURES

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 June 30, 2014 and December 31, 2013 that are recorded at fair value on a recurring basis are the assets held in the Supplemental Executive Retirement Program (“SERP”). We base the valuations related to this asset on the observable market values of the investments that comprise the SERP (Level 2 inputs).

The fair values of these assets at June 30, 2014 and December 31, 2013 were as follows (in thousands):

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 June 30, 2014 may differ significantly from the amounts presented.

Following is a summary of significant methodologies used in estimating fair values and a schedule of fair values at June 30, 2014 .

Cash and Cash Equivalents and Restricted Cash

Cash and cash equivalents and restricted cash include 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 (Level 1 inputs).

Notes Receivable

We acquired a note receivable ("2445 M Street note") in 2008 with the purchase of 2445 M Street. We estimate the fair value of the 2445 M Street note based on a discounted cash flow methodology using market discount rates (Level 3 inputs).

Debt

Mortgage notes payable consist of instruments in which certain of our real estate assets are used for collateral. We estimate the fair value of the mortgage notes payable 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 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. We estimate the market value based on a comparison of the spreads of the advances to market given the adjustable base rate. We estimate the fair value of the notes payable 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. We

classify these fair value measurements as Level 3 as we use significant unobservable inputs and management judgment due to the absence of quoted market prices.

As of June 30, 2014 and December 31, 2013 , the carrying values and estimated fair values of our financial instruments were as follows (in thousands):

NOTE 9: EARNINGS PER COMMON SHARE

We determine “Basic earnings per share” using the two-class method as our unvested restricted share awards and units 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 earnings to unvested restricted share awards and units 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 dilutive earnings per share calculation includes the dilutive impact of employee stock options based on the treasury stock method and our incentive share awards with performance or market conditions under the contingently issuable method. The diluted earnings per share calculation also considers operating partnership units (if any) under the if-converted method. We have a loss from continuing operations for the 2014 Period, and therefore diluted earnings per share is calculated in the same manner as basic earnings per share for this period.

The computations of basic and diluted earnings per share for the three and six months ended June 30, 2014 and 2013 were as follows (in thousands, except per share data):
