⁽¹⁾ Adjusted EBITDA is earnings before interest expense, taxes, depreciation, amortization, gain/loss on sale of real estate, casualty gain/loss, real estate impairment, gain/loss on extinguishment of debt, severance expense, relocation expense, acquisition and structuring expense, gain from non-disposal activities and allocations to noncontrolling interests. 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, and the cost of debt or non-operating gains and losses. Adjusted EBITDA is a non-GAAP measure.

⁽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⁾ Consolidated Total Asset Value is the sum of unrestricted cash plus the quotient of applying a capitalization rate to the annualized NOI from the most recently ended quarter for each asset class, excluding NOI from disposed properties, acquisitions during the past 6 quarters, development, major redevelopment and low occupancy properties. To this amount, we add the purchase price of acquisitions during the past 6 quarters plus values for development, major redevelopment and low occupancy properties.
⁽⁴⁾ Consolidated Adjusted EBITDA is defined as earnings before noncontrolling interests, depreciation, amortization, interest expense, income tax expense, acquisition costs, extraordinary, unusual or nonrecurring transactions including sale of assets, impairment, gains and losses on extinguishment of debt and other non-cash charges.
⁽⁵⁾ Consolidated Fixed Charges consist of interest expense excluding capitalized interest and amortization of deferred financing costs, principal payments and preferred dividends, if any.
⁽⁶⁾Unencumbered Pool Value is the sum of unrestricted cash plus the quotient of applying a capitalization rate to the annualized NOI from unencumbered properties from the most recently ended quarter for each asset class excluding NOI from disposed properties, acquisitions during the past 6 quarters, development, major redevelopment and low occupancy properties. To this we add the purchase price of unencumbered acquisitions during the past 6 quarters and values for unencumbered development, major redevelopment and low occupancy properties.

⁽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. The earnings to fixed charges ratio for the three months ended June 30, 2018 and December 31, 2017 include gains on the sale of real estate of $2.5M and $24.9 million respectively.
⁽²⁾Debt service coverage ratio is computed by dividing Adjusted EBITDA (see page 8) by interest expense and principal amortization.

Supplemental Definitions

June 30, 2018

Adjusted EBITDA (a non-GAAP measure) is earnings attributable to the controlling interest before interest expense, taxes, depreciation, amortization, real estate impairment, casualty gain, gain/loss on sale of real estate, gain/loss on extinguishment of debt, severance expense, relocation expense, acquisition and structuring expenses 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.

Average occupancy is based on monthly occupied net rentable square footage as a percentage of total net rentable square footage, except for the rows labeled "Multifamily (calculated on a unit basis)," on which average occupancy is based on average monthly occupied units as a percentage of total units. The square footage for multifamily properties only includes residential space. The occupied square footage for office and retail properties includes temporary lease agreements.

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, severance expense, relocation expense, acquisition and structuring expenses 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.

Ending Occupancy is calculated as occupied square footage as a percentage of total square footage as of the last day of that period. Multifamily unit basis ending occupancy is calculated as occupied units as a percentage of total units as of the last day of that period.

NAREIT Funds from operations ("NAREIT FFO") is defined by 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, impairment of depreciable real estate and real estate depreciation and amortization. We consider NAREIT 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 NAREIT 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 real estate investment trusts. These other REITs may not define the term in accordance with the current NAREIT definition or may interpret the current NAREIT definition differently. NAREIT FFO is a non-GAAP measure.

Core Funds From Operations ("Core FFO") is calculated by adjusting NAREIT FFO for the following items (which we believe are not indicative of the performance of Washington REIT’s operating portfolio and affect the comparative measurement of Washington REIT’s operating performance over time): (1) gains or losses on extinguishment of debt, (2) expenses related to acquisition and structuring activities, (3) executive transition costs and severance expense related to corporate reorganization and related to executive retirements or resignations, (4) property impairments, casualty gains and losses, and gains or losses on sale not already excluded from NAREIT FFO, as appropriate, and (5) relocation expense. 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 Washington REIT’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 NAREIT FFO (1) recurring expenditures, tenant improvements and leasing costs, that are capitalized and amortized and are necessary to maintain our properties and revenue stream (excluding items contemplated prior to acquisition or associated with development / redevelopment of a property) 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 performance 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 Washington REIT’s operating portfolio and affect the comparative measurement of Washington REIT’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 related to executive retirements or resignations, (4) property impairments, casualty gains and losses, and gains or losses on sale not already excluded from FAD, as appropriate, and (5) relocation expense. 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 performance measure of Washington REIT’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.

Net Operating Income (“NOI”) is a non-GAAP measure defined as real estate rental revenue less real estate expenses. NOI is calculated as net income, less non-real estate revenue and the results of discontinued operations (including the gain on sale, if any), plus interest expense, depreciation and amortization, general and administrative expenses, acquisition costs, real estate impairment, casualty gains and losses, and gain or loss on extinguishment of debt. We also present NOI on a cash basis ("Cash NOI") which is calculated as NOI less the impact of straightlining of rent and amortization of market intangibles. We provide each of NOI and cash NOI as a supplement to net income calculated in accordance with GAAP. As such, neither should be considered an alternative to net income as an indication of our operating performance. They are the primary performance measures we use to assess the results of our operations at the property level.

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 properties that were owned for the entirety of the years being compared, and exclude properties under redevelopment or development and properties acquired, sold or classified as held for sale during the years being compared. We define development properties as those for which we have planned or ongoing major construction activities on existing or acquired land pursuant to an authorized development plan. We consider a property's development activities to be complete when the property is ready for its intended use. The property is categorized as same-store when it has been ready for its intended use for the entirety of the years being compared. We define redevelopment properties as those for which have planned or ongoing significant development and construction activities on existing or acquired buildings pursuant to an authorized plan, which has an impact on current operating results, occupancy and the ability to lease space with the intended result of a higher economic return on the property. We categorize a redevelopment property as same-store when redevelopment activities have been complete for the majority of each year being compared.

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