WRIT is diversified, as it invests in office, medical office, retail, and multifamily properties and land for development.

2012 Highlights

In 2012 WRIT continued to improve the quality of its portfolio by acquiring a well-located office building near Metro in the Ballston submarket of Arlington, Virginia, selling an outer perimeter office and medical office property, and modernizing existing properties to attract and retain the best tenants.

WRIT posted same-store GAAP rental rate growth of 1.5% in 2012 and executed nearly 1 million square feet of commercial lease transactions.

On the capital side, WRIT priced an underwritten public offering of $300 million aggregate principal amount of senior unsecured notes due October 15, 2022. The notes have an annual coupon rate of 3.95% and were priced at 99.438% of the principal amount. J.P. Morgan Securities LLC, Citigroup Global Markets Inc., Wells Fargo Securities, LLC and Credit Suisse Securities (USA) LLC were the Joint Book-Running Managers for the offering.

WRIT prepaid without penalty a total of seven property mortgages totaling approximately $80 million, amended and extended its unsecured credit facilities with SunTrust and Wells Fargo, and entered into a new a Sales Agency Financing Agreement with BNY Mellon Capital Markets, LLC (BNYMCM).

Fourth Quarter 2012 Update

WRIT sold Plumtree Professional Center, a 33,000 square foot medical office building in Bel Air, Maryland, for $8.75 million and a net book gain of $1.4 million. The property was built in 1991 and acquired by WRIT as part of a portfolio acquisition in 2006. The unleveraged internal rate of return over the holding period was 13%.

In the fourth quarter, WRIT prepaid without penalty five mortgage notes totaling approximately $58.8 million, including 15005 Shady Grove Road, 9707 Medical Center Drive, 8501-8503 Arlington Boulevard, 8505 Arlington Boulevard, and Plumtree Professional Center. The weighted average interest rate on these five notes was 5.43%. Subsequent to quarter end, WRIT prepaid without penalty the West Gude 5.855% mortgage note for $30.0 million.

WRIT signed commercial leases for 270,000 square feet with an average lease term of 6.2 years.

Commercial tenant improvement costs were $19.71 per square foot and leasing commissions and incentives were $9.83 per square foot for the quarter.

As of December 31, 2012, WRIT owned a diversified portfolio of 70 properties totaling approximately 9 million square feet of commercial space and 2,540 residential units, and land held for development.

(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⁾ Total Assets is calculated by applying a capitalization rate of 7.50% to the EBITDA⁽⁴⁾ 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⁽⁴⁾ from unencumbered properties from the last four consecutive quarters, excluding EBITDA from acquired, disposed, and non-stabilized development properties.

⁽³⁾ Tangible Net Worth is defined as shareholders equity less accumulated depreciation at the commitment start date plus current accumulated depreciation.

⁽⁴⁾ EBITDA is defined in our debt covenants as earnings before minority interests, depreciation, amortization, interest expense, income tax expense, and extraordinary and nonrecurring gains and losses.

⁽⁵⁾ Gross Asset Value is calculated by applying a capitalization rate to the annualized EBITDA⁽⁴⁾ 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.

⁽⁶⁾ Fixed Charges consist of interest expense, principal payments, ground lease payments and replacement reserve payments.

⁽⁷⁾Unencumbered Pool Value is calculated by applying a capitalization rate of 7.50% 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.

⁽⁸⁾Investments is defined as development in progress, including land held for development, plus budgeted development costs upon commencement of construction, if any.

⁽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 8) by interest expense and principal amortization.

Supplemental Definitions December 31, 2012

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.

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

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.

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

Earnings to fixed charges ratio 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.

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.

Funds from operations ("FFO") is defined by The National Association of Real Estate Investment Trusts, Inc. (“NAREIT”) in an April, 2002 White Paper as net income (computed in accordance with generally accepted accounting principles (“GAAP”)) excluding gains (or losses) associated with sales of property and impairment of depreciable real estate, 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.

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, (3) severance expense related to corporate reorganization, and (4) property impairments not already excluded from FFO, 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.

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.

Core Funds Available for Distribution ("Core FAD") is calculated by adjusting FAD 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, (3)non-share-based severance expense related to corporate reorganization, and (4) property impairments not already excluded from FAD, 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 FAD serves as a useful, supplementary measure of WRIT’s ability to incur and service debt, and distribute dividends to its shareholders. Core FAD is a non-GAAP and non-standardized measure, and may be calculated differently by other REITs.

The Industrial Portfolio consists of every industrial property, as well as two office properties, the Crescent and Albemarle Point. We executed the sale in three phases. Phase I of the Industrial Portfolio sale consisted of industrial properties (8880 Gorman Road, Dulles South IV, Fullerton Business Center, Hampton Overlook, Alban Business Center, Pickett Industrial Park, Northern Virginia Industrial Park I, 270 Technology Park, Fullerton Industrial Center, Sully Square, 9950 Business Parkway, Hampton South and 8900 Telegraph Road) and two office properties (Crescent and Albemarle Point). On October 3, 2011 we closed on Phase II of the Industrial Portfolio sale, consisting of Northern Virginia Industrial Park II. We closed on Phase III of the Industrial Portfolio sale on November 1, 2011, consisting of 6100 Columbia Park Road and Dulles Business Park.

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

Recurring capital expenditures represent 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.
