Government Properties Income Trust Supplemental Operating and Financial Data, June 30, 2017 COM PAN Y PROFIL E 6 COMPANY PROFILE The Company: Government Properties Income Trust, or GOV, we or us, is a real estate investment trust, or REIT, which primarily owns properties located throughout the United States that are majority leased to government tenants. The majority of our properties are office buildings. As of June 30, 2017, we also own 24.9 million common shares, or approximately 27.9% of the then outstanding common shares, of Select Income REIT (Nasdaq: SIR), or SIR, a REIT which owns properties that are primarily leased to single tenants. We have been investment grade rated since 2010, and we are included in the S&P Small Cap 600 Index, the Russell 2000® index and the MSCI US REIT index. Management: GOV is managed by The RMR Group LLC, the operating subsidiary of The RMR Group Inc. (Nasdaq: RMR). RMR is an alternative asset management company that was founded in 1986 to manage real estate companies and related businesses. RMR primarily provides management services to four publicly owned REITs and three real estate related operating businesses. In addition to managing GOV, RMR manages Hospitality Properties Trust, a REIT that owns hotels and travel centers, Senior Housing Properties Trust, a REIT that primarily owns healthcare, senior living and medical office buildings, and SIR, a REIT which owns properties that are primarily leased to single tenants. RMR also provides management services to TravelCenters of America LLC, a publicly traded operator of travel centers along the U.S. Interstate Highway System, convenience stores and restaurants, Five Star Senior Living Inc., a publicly traded operator of senior living communities, and Sonesta International Hotels Corporation, a privately owned franchisor and operator of hotels and cruise ships. RMR also manages publicly traded securities of real estate companies and private commercial real estate debt funds through wholly owned SEC registered investment advisory subsidiaries. As of June 30, 2017, RMR had $27.9 billion of real estate assets under management and the combined RMR managed companies had approximately $11 billion of annual revenues, over 1,400 properties and approximately 53,000 employees. We believe that being managed by RMR is a competitive advantage for GOV because of RMR’s depth of management and experience in the real estate industry. We also believe RMR provides management services to us at costs that are lower than we would have to pay for similar quality services.

(2) We report rental income on a straight line basis over the terms of the respective leases; accordingly, rental income includes non-cash straight line rent adjustments. Rental income also includes expense reimbursements, tax escalations, parking revenues, service income and other fixed and variable charges paid to us by our tenants, as well as the net effect of non-cash amortization of intangible lease assets and liabilities.

Government Properties Income Trust Supplemental Operating and Financial Data, June 30, 2017 NON-GAA P FINANCIA L MEASURES DEFINITION S 23 DEFINITIONS OF CERTAIN NON-GAAP FINANCIAL MEASURES Definition of NOI and Cash Basis NOI We calculate NOI and Cash Basis NOI as shown on page 19. 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 property level results of operations. We define NOI as income from our rental of real estate less property operating expenses. NOI excludes amortization of capitalized tenant improvement costs and leasing commissions because we record those amounts as depreciation and amortization. We define Cash Basis NOI as NOI excluding non-cash straight line rent adjustments, lease value amortization and non-cash amortization included in other operating expenses. 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 to evaluate individual and company wide 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 generated and incurred at the property level and may facilitate comparisons of our operating performance between periods and with other REITs. 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 or operating income as an indicator of our operating performance or as a measure of our liquidity. These measures should be considered in conjunction with net income and operating income as presented in our Condensed Consolidated Statements of Income. Other REITs and real estate companies may calculate NOI and Cash Basis NOI differently than we do. Definition of EBITDA and Adjusted EBITDA We calculate EBITDA and Adjusted EBITDA as shown on page 21. We consider EBITDA and Adjusted EBITDA to be appropriate supplemental measures of our operating performance, along with net income and operating income. 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 or operating income as an indicator of operating performance or as a measure of GOV’s liquidity. These measures should be considered in conjunction with net income and operating income as presented in our Condensed Consolidated Statements of Income. Other REITs and real estate companies may calculate EBITDA and Adjusted EBITDA differently than we do. Definition of FFO and Normalized FFO We calculate FFO and Normalized FFO as shown on page 22. FFO is calculated on the basis defined by The National Association of Real Estate Investment Trusts, or NAREIT, which is net income, calculated in accordance with GAAP, plus real estate depreciation and amortization and the difference between FFO attributable to an equity investment and equity in earnings of an equity investee but excluding impairment charges on real estate assets, any gain or loss on sale of properties, as well as certain other adjustments currently not applicable to us. Our calculation of Normalized FFO differs from NAREIT's definition of FFO because we include the difference between FFO and Normalized FFO attributable to our equity investment in SIR, we include business management incentive fees, if any, only in the fourth quarter versus the quarter when they are recognized as expense in accordance with GAAP due to their quarterly volatility not necessarily being indicative of our core operating performance and the uncertainty as to whether any such business management incentive fees will be payable when all contingencies for determining such fees are known at the end of the calendar year and we exclude acquisition related costs expensed under GAAP, gains and losses on issuance of shares by SIR and gains on early extinguishment of debt. We consider FFO and Normalized FFO to be appropriate supplemental measures of operating performance for a REIT, along with net income and operating income. 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. Other factors include, but are not limited to, requirements to maintain our qualification for taxation as a REIT, limitations in our credit agreement and public debt covenants, the availability to us of debt and equity capital, our expectation of our future capital requirements and operating performance, our receipt of distributions from SIR and our expected needs and availability of cash to pay our obligations. 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 or operating income as an indicator of our operating performance or as a measure of our liquidity. These measures should be considered in conjunction with net income and operating income as presented in our Condensed Consolidated Statements of Income. Other REITs and real estate companies may calculate FFO and Normalized FFO differently than we do.
