EQC recognized a gain on this sale of an equity investment of $66,293 as a result of the per share sale price being above EQC's per share carrying value. On July 2, 2013, SIR issued and sold to the public 10,500,000 of its common shares of beneficial interest in an underwritten public offering. Prior to this offering, EQC's 22,000,000 common shares of SIR represented more than 50% of SIR's outstanding common shares and SIR's financial position and results of operations were consolidated in EQC's financial statements. Beginning on July 2, 2013, EQC no longer consolidates its investment in SIR, but instead accounts for its investment in SIR under the equity method. In addition, in May and June 2014, SIR issued 10,000,000 of its common shares in a public offering, which reduced EQC's ownership interest in SIR to 36.7%. EQC recognized a gain on this sale by an equity investee of $16,911 as a result of the per share sales price of this transaction being above EQC's per share carrying value. On July 9, 2014, EQC sold its entire stake of 22,000,000 common shares of SIR. Affiliates Insurance Company, or AIC, is a private company that, until May 9, 2014, was owned equally by Reit Management & Research LLC, or RMR, and each of the public companies to which RMR provides management services, including EQC and SIR. The amounts presented include SIR's equity investment in AIC from May 2012 until July 2, 2013 when SIR was no longer EQC's consolidated subsidiary. On May 9, 2014, as a result of the change in control of EQC and in accordance with the terms of a shareholders agreement among EQC and the other AIC shareholders, the other AIC shareholders purchased pro rata from EQC all 20,000 shares of AIC that EQC then owned for aggregate proceeds of $5,776.

Funds from Operations (FFO) and Normalized FFO Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) and Adjusted EBITDA DEFINITIONS We compute FFO in accordance with standards established by the National Association of Real Estate Investment Trusts (NAREIT). NAREIT defines FFO as net income (loss), calculated in accordance with GAAP, excluding real estate depreciation and amortization, gains (or losses) from sales of depreciable property, impairment of depreciable real estate, and our portion of these items related to equity investees and noncontrolling interests. Normalized FFO begins with FFO and excludes lease value amortization, straight line rent, gains and losses on early extinguishment of debt, gains and losses on the sale of equity investments, gains and losses on the issuance of shares by an equity investee, shareholder litigation and transition-related expenses, acquisition related costs, interest earned from direct financing lease, and our portion of these items related to equity investees and noncontrolling interests. Normalized FFO also includes the minimum cash rent from direct financing lease. We consider FFO and Normalized FFO to be appropriate measures of operating performance for a REIT, along with net income, net income attributable to Equity Commonwealth, net income available for EQC common shareholders, operating income and cash flow from operating activities. We believe that FFO and Normalized FFO provide useful information to investors because by excluding the effects of certain historical amounts, such as depreciation expense, FFO and Normalized FFO may facilitate a comparison of our operating performance between periods and with other REITs. FFO and Normalized FFO are among the factors considered by our Board of Trustees when determining the amount of distributions to our shareholders. FFO and Normalized FFO do not represent cash generated by operating activities in accordance with GAAP and should not be considered as alternatives to net income, net income attributable to Equity Commonwealth, net income available for EQC common shareholders, operating income or cash flow from operating activities, determined in accordance with GAAP, or as indicators of our financial performance or liquidity, nor are these measures necessarily indicative of sufficient cash flow to fund all of our needs. These measures should be considered in conjunction with net income, net income attributable to Equity Commonwealth, net income available for EQC common shareholders, operating income and cash flow from operating activities as presented in our condensed consolidated statements of operations, condensed consolidated statements of comprehensive income (loss) and condensed consolidated statements of cash flows. Other REITs and real estate companies may calculate FFO and Normalized FFO differently than we do. We calculate EBITDA as net income (loss) excluding 1) interest expense, 2) income tax expense, 3) depreciation and amortization, and 4) our portion of these items related to equity investees. We calculate Adjusted EBITDA as EBITDA excluding 1) loss on asset impairment, 2) acquisition related costs, 3) loss on early extinguishment of debt, 4) shareholder litigation costs and transition-related expenses, 5) gains or losses on sale of properties, 6) gains or losses on sale of equity investments, 7) gains or losses on issuance of shares by an equity investee, and 8) our portion of these items related to equity investees. We consider EBITDA and Adjusted EBITDA to be appropriate measures of our operating performance, along with net income, net income attributable to Equity Commonwealth, net income available for EQC common shareholders, operating income and cash flow from operating activities. We believe that EBITDA and Adjusted EBITDA provide useful information to investors because by excluding the effects of certain historical amounts, such as interest, depreciation and amortization expense, EBITDA and Adjusted EBITDA may facilitate a comparison of current operating performance with our past operating performance. EBITDA and Adjusted EBITDA do not represent cash generated by operating activities in accordance with GAAP and should not be considered alternatives to net income, net income attributable to Equity Commonwealth, net income available for EQC common shareholders, operating income or cash flow from operating activities, determined in accordance with GAAP, or as indicators of our financial performance or liquidity, nor are these measures necessarily indicative of sufficient cash flow to fund all of our needs. These measures should be considered in conjunction with net income, net income attributable to Equity Commonwealth, net income available for EQC common shareholders, operating income and cash flow from operating activities as presented in our condensed consolidated statements of operations, condensed consolidated statements of comprehensive income (loss) and condensed consolidated statements of cash flows. Other REITs and real estate companies may calculate EBITDA and Adjusted EBITDA differently than we do. 30

Net Operating Income (NOI) and Cash Basis NOI Tenant Improvements Capital expenditures to improve tenants' space or amounts paid directly to tenants to improve their space. Leasing Costs Building Improvements Expenditures to replace obsolete building components and expenditures that extend the useful life of existing assets. We define NOI as income from our real estate including lease termination fees received from tenants less our property operating expenses, which expenses include property marketing costs. NOI excludes amortization of capitalized tenant improvement costs and leasing commissions. We define Cash Basis NOI as NOI less non cash straight line rent adjustments, lease value amortization and lease termination fees. We consider NOI and Cash Basis NOI to be appropriate supplemental measures to net income because they may help both investors and management to understand the operations of our properties. We use NOI and Cash Basis NOI internally to evaluate individual, regional and combined property level performance, and we believe that NOI and Cash Basis NOI provide useful information to investors regarding our results of operations because they reflect only those income and expense items that are incurred at the property level and may facilitate comparisons of our operating performance between periods and with other REITs. The calculations of NOI and Cash Basis NOI exclude certain components of net income in order to provide results that are more closely related to our properties' results of operations. NOI and Cash Basis NOI do not represent cash generated by operating activities in accordance with GAAP, and should not be considered as alternatives to net income, net income attributable to Equity Commonwealth, net income available for EQC common shareholders, operating income or cash flow from operating activities, determined in accordance with GAAP, or as indicators of our financial performance or liquidity, nor are these measures necessarily indicative of sufficient cash flow to fund all of our needs. These measures should be considered in conjunction with net income, net income attributable to Equity Commonwealth, net income available for EQC common shareholders, operating income and cash flow from operating activities as presented in our condensed consolidated statements of operations, condensed consolidated statements of comprehensive income (loss) and condensed consolidated statements of cash flows. Other REITs and real estate companies may calculate NOI and Cash Basis NOI differently than we do. Leasing related costs such as brokerage commissions and related legal expenses. Development, Redevelopment and Other Activities Includes 1) major capital expenditures that are identified at the time of a property acquisition and incurred within a short time period after acquiring the property, and 2) major capital expenditure projects that reposition a property or result in new sources of revenue. 31
