Washington Real Estate Investment Trust (“WRIT”) is a self-administered, self-managed, equity real estate investment trust investing in income-producing properties in the greater Washington metro region. WRIT is diversified, as it invests in office, medical office, industrial/flex, retail, and multifamily properties and land for development.

In the first quarter of 2011, WRIT acquired two downtown Washington, DC office assets. 1140 Connecticut Avenue is a twelve story, 184,000 square foot office building with a three level parking garage. The purchase price was $80.25 million. The property was 99% leased at the time of purchase to 25 office tenants and four retail tenants. It is located near the intersection of Connecticut Avenue and M Street in the heart of Washington’s “Golden Triangle” Central Business District, less than one block from the Farragut North Metro Station (Red Line) and two blocks from the Farragut West Metro Station (Blue and Orange Lines). WRIT funded this acquisition using available cash and its line of credit, and expects to achieve a first year unleveraged yield on 6.0% on a cash basis.

The second downtown office acquisition, 1227 25th Street, is an eight story, 130,000 square foot building with a two level parking garage. The purchase price was $47.0 million. The property was 72% leased at the time of purchase to the GSA and law firm tenants. It is located near the corner of 25th and M Streets in Washington’s West End submarket, immediately adjacent to WRIT’s 2445 M Street office building acquired in 2008. WRIT funded this acquisition using available cash and its line of credit, and projects a stabilized cash yield of 8.7%.

Subsequent to quarter end, WRIT completed the sale of Dulles Station West Phase I, a 180,000 square foot office building in Herndon, Virginia, for $58.8 million. WRIT acquired the land for Dulles Station West Phases I and II in 2005 and completed construction on Phase I in 2007. It is 100% leased to tenants including IBM and National Student Clearinghouse. Phase II, which was not included in the transaction, is zoned for future development of a 340,000 square foot office building.

WRIT signed commercial leases for 416,000 square feet with an average lease term of 4.9 years. The average rental rate increase on new and renewal leases was -0.6% on a GAAP basis and -7.5% on a cash basis. Commercial tenant improvement costs were $3.09 per square foot and leasing costs were $3.56 per square foot for the quarter.

As of March 31, 2011, WRIT owned a diversified portfolio of 87 properties totaling approximately 11 million square feet of commercial space and 2,540 residential units, and land held for development. These 87 properties consist of 27 office properties, 18 medical office properties, 16 industrial/flex properties, 15 retail centers and 11 multifamily properties. WRIT shares are publicly traded on the New York Stock Exchange (NYSE:WRE).

With investments in the office, medical office, industrial/flex, retail and multifamily segments, WRIT is uniquely diversified. This balanced portfolio provides stability during market fluctuations in specific property types.

⁽¹⁾

Funds From Operations (“FFO”) - The National Association of Real Estate Investment Trusts, Inc. (“NAREIT”) defines FFO (April, 2002 White Paper) as net income (computed in accordance with generally accepted accounting principles (“GAAP”)) excluding gains (or losses) from sales of property plus real estate depreciation and amortization. We consider FFO to be a standard supplemental measure for equity real estate investment trusts (“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. FFO is a non-GAAP measure.

⁽²⁾

Funds Available for Distribution (“FAD”) is calculated by subtracting from FFO (1) recurring expenditures, tenant improvements and leasing costs, that are capitalized and amortized and are necessary to maintain our properties and revenue stream and (2) straight line rents, then adding (3) non-real estate depreciation and amortization, (4) non-cash fair value interest expense and (5) amortization of restricted share compensation, then adding or subtracting the (6) amortization of lease intangibles, (7) real estate impairment and (8) non-cash gain/loss on extinguishment of debt, as appropriate. FAD is included herein, because we consider it to be a measure of a REIT’s ability to incur and service debt and to distribute dividends to its shareholders. FAD is a non-GAAP and non-standardized measure, and may be calculated differently by other REITs.

⁽³⁾

Core Funds From Operations (“Core FFO”) is calculated by adjusting FFO for the following items (which we believe are not indicative of the performance of WRIT’s operating portfolio and affect the comparative measurement of WRIT’s operating performance over time): (1) gains or losses on extinguishment of debt, (2) costs related to the acquisition of properties and (3) property impairments, as appropriate. These items can vary greatly from period to period, depending upon the volume of our acquisition activity and debt retirements, among other factors. We believe that by excluding these items, Core FFO serves as a useful, supplementary measure of WRIT’s ability to incur and service debt, and distribute dividends to its shareholders. Core FFO is a non-GAAP and non-standardized measure, and may be calculated differently by other REITs.

⁽¹⁾

Adjusted EBITDA is earnings before interest expense, taxes, depreciation, amortization, gain on sale of real estate, gain/loss on extinguishment of debt and gain from non-disposal activities. We consider Adjusted EBITDA to be an appropriate supplemental performance measure because it permits investors to view income from operations without the effect of depreciation, the cost of debt or non-operating gains and losses. Adjusted EBITDA is a non-GAAP measure.

⁽¹⁾	Balance includes the mortgage note payable secured by The Ridges, a property we sold on December 21, 2010, which has been reclassified to “Other liabilities related to properties sold or held for sale.” We repaid this mortgage note payable without penalty on July 12, 2010.

⁽²⁾

On December 1, 2009, we borrowed $100.0 million on a line of credit in order to prepay the $100.0 million term loan. Through February 19, 2010, the interest rate on this $100.0 million borrowing on our lines of credit is effectively fixed by an interest rate swap at 3.375%. Beginning February 20, 2010 through November 1, 2011, an interest rate swap effectively fixes the interest rate at 2.525%.

⁽¹⁾	Total Assets is calculated by applying a capitalization rate of 7.50% to the EBITDA⁽³⁾ from the last four consecutive quarters, excluding EBITDA from acquired, disposed, and non-stabilized development properties.

⁽²⁾	Total Unencumbered Assets is calculated by applying a capitalization rate of 7.50% to the EBITDA⁽³⁾ from unencumbered properties from the last four consecutive quarters, excluding EBITDA from acquired, disposed, and non-stabilized development properties.

⁽³⁾	EBITDA is defined in our debt covenants as earnings before interest income, interest expense, taxes, depreciation, amortization, gain on sale of real estate, real estate impairments, gain/loss on extinguishment of debt and gain from non-disposal activities.

⁽⁴⁾

Gross Asset Value is calculated by applying a capitalization rate to the annualized EBITDA⁽³⁾ from the most recently ended quarter, excluding EBITDA from disposed properties and current quarter acquisitions. To this amount, the purchase price of current quarter acquisitions, cash and cash equivalents and development in progress is added.

⁽⁵⁾	Fixed Charges consist of interest expense, principal payments, ground lease payments and replacement reserve payments.

⁽⁶⁾	Non-Wholly Owned Assets is calculated by applying a capitalization rate of 7.50% to the EBITDA⁽³⁾ from properties subject to a joint operating agreement (i.e. NVIP I&II). We add to this amount the development in progress subject to a joint operating agreement (i.e. 4661 Kenmore Avenue).

⁽⁷⁾	Unencumbered Pool Value is calculated by applying a capitalization rate of 7.75% to the net operating income from unencumbered properties owned for the entire quarter. To this we add the purchase price of unencumbered acquisitions during the current quarter and development in progress.

⁽¹⁾

The ratio of earnings to fixed charges is computed 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, plus interest costs capitalized.

⁽²⁾	Debt service coverage ratio is computed by dividing Adjusted EBITDA (see page 7) by interest expense and principal amortization.

⁽³⁾	“Total Debt” balance includes a $22.5 million mortgage notes payable secured by The Ridges, a property we sold on December 21, 2010, that has been reclassified to “Other liabilities related to properties sold or held for sale.” We repaid this mortgage note payable without penalty on July 12, 2010.

Annualized base rent (ABR) is calculated as monthly base rent (cash basis) per the lease, as of the reporting period, multiplied by 12.

Debt to total market capitalization is total debt from the balance sheet divided by the sum of total debt from the balance sheet plus the market value of shares outstanding at the end of the period.

Adjusted EBITDA (a non-GAAP measure) is earnings attributable to the controlling interest before interest expense, taxes, depreciation, amortization, real estate impairment, gain on sale of real estate, gain/loss on extinguishment of debt and gain/loss from non-disposal activities.

Ratio of earnings to fixed charges is computed by dividing earnings attributable to the controlling interest by fixed charges. For this purpose, earnings consist of income from continuing operations (or net income if there are no discontinued operations) plus fixed charges, less capitalized interest. Fixed charges consist of interest expense (excluding interest expense from discontinued operations), including amortized costs of debt issuance, plus interest costs capitalized.

Debt service coverage ratio is computed by dividing earnings attributable to the controlling interest before interest expense, taxes, depreciation, amortization, real estate impairment, gain on sale of real estate, gain/loss on extinguishment of debt and gain/loss from non-disposal activities by interest expense (including interest expense from discontinued operations) and principal amortization.

Funds from operations (FFO) - The National Association of Real Estate Investment Trusts, Inc. (NAREIT) defines FFO (April, 2002 White Paper) as net income atributable to the controlling interest (computed in accordance with generally accepted accounting principles (GAAP)) excluding gains (or losses) from sales of property plus real estate depreciation and amortization. FFO is a non-GAAP measure.

Core Funds From Operations (Core FFO), a non-GAAP measure, is calculated by adjusting FFO for (1) gains or losses on extinguishment of debt, (2) costs related to the acquisition of properties and (3) real estate impairments, as appropriate.

Funds Available for Distribution (FAD), a non-GAAP measure, is calculated by subtracting from FFO recurring expenditures, tenant improvements, leasing incentives and leasing costs, that are capitalized and amortized and are necessary to maintain our properties and revenue stream, non-cash gain/loss from extinguishment of debt and straight line rents, then adding non-real estate depreciation and amortization, real estate impairment, non-cash fair value interest expense, adding or subtracting amortization of lease intangibles and amortization of restricted share compensation, as appropriate.

Core Funds Available for Distribution (Core FAD), a non-GAAP measure, is calculated by adjusting FAD for (1) cash gains or losses on extinguishment of debt, (2) costs related to the acquisition of properties and (3) real estate impairments, as appropriate.

Recurring capital expenditures represents non-accretive building improvements and leasing costs required to maintain current revenues. Recurring capital expenditures do not include acquisition capital that was taken into consideration when underwriting the purchase of a building or which are incurred to bring a building up to “operating standard.”

Rent increases on renewals and rollovers are calculated as the difference, weighted by square feet, of the net ABR due the first month after a term commencement date and the net ABR due the last month prior to the termination date of the former tenant’s term.

Same-store portfolio properties include all properties that were owned for the entirety of the current and prior year reporting periods.

Same-store portfolio net operating income (NOI) growth is the change in the NOI of the same-store portfolio properties from the prior reporting period to the current reporting period.

Physical occupancy is calculated as occupied square footage as a percentage of total square footage as of the last day of that period.

Economic occupancy is calculated as actual real estate rental revenue recognized for the period indicated as a percentage of gross potential real estate rental revenue for that period. We determine gross potential real estate rental revenue by valuing occupied units or square footage at contract rates and vacant units or square footage at market rates for comparable properties. We do not consider percentage rents and expense reimbursements in computing economic occupancy percentages.
