Newton, MA (April 27, 2017): Government Properties Income Trust (Nasdaq: GOV) today announced its financial results for the quarter ended March 31, 2017.

Net income determined in accordance with U.S. generally accepted accounting principles, or GAAP, was $7.4 million, or $0.10 per diluted share, for the quarter ended March 31, 2017, compared to net income of $17.4 million, or $0.24 per diluted share, for the quarter ended March 31, 2016. The weighted average number of diluted common shares outstanding was 71.1 million for the quarter ended March 31, 2017, and 71.0 million for the quarter ended March 31, 2016.

Leasing, Occupancy and Same Property Results:

During the quarter ended March 31, 2017, GOV entered into new and renewal leases for 360,103 rentable square feet at weighted (by rentable square feet) average rents that were 5.2% above prior rents for the same space. The weighted average (by rentable square feet) lease term for leases entered into during the quarter ended March 31, 2017 was 10.6 years. Leasing capital commitments for new and renewal leases entered into during the quarter ended March 31, 2017 were $2.2 million, or $0.59 per square foot, per weighted average lease year.

As of March 31, 2017, 95.1% of GOV’s rentable square feet at properties classified as continuing operations was leased. This compares with 95.1% as of December 31, 2016 and 94.9% as of March 31, 2016. Occupancy for properties classified as continuing operations and owned continuously since January 1, 2016, or same properties, was 95.1% as of March 31, 2017, which compares with 95.1% as of December 31, 2016 and 95.4% as of March 31, 2016. Same properties net operating income, or NOI, increased 0.8% and same properties cash basis NOI, or Cash Basis NOI, decreased 1.4% for the quarter ended March 31, 2017 compared to the same period in 2016.

(1)

GOV calculates FFO and Normalized FFO as shown above. 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 GOV. GOV's calculation of Normalized FFO differs from NAREIT's definition of FFO because GOV includes the difference between FFO and Normalized FFO attributable to GOV’s equity investment in Select Income REIT, or SIR, GOV includes 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 GOV’s 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 determined at the end of the calendar year, and GOV excludes acquisition related costs and gains on early extinguishment of debt. GOV considers FFO and Normalized FFO to be appropriate supplemental measures of operating performance for a REIT, along with net income and operating income. GOV believes 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 GOV's operating performance between periods and with other REITs. FFO and Normalized FFO are among the factors considered by GOV's Board of Trustees when determining the amount of distributions to its shareholders. Other factors include, but are not limited to, requirements to maintain GOV's qualification for taxation as a REIT, limitations in GOV’s credit agreement and public debt covenants, the availability to GOV of debt and equity capital, GOV's expectation of its future capital requirements and operating performance, GOV’s receipt of distributions from SIR and GOV’s expected needs and availability of cash to pay its 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 GOV's 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 GOV's Condensed Consolidated Statements of Income. Other REITs and real estate companies may calculate FFO and Normalized FFO differently than GOV does.

(1)

GOV calculates NOI and Cash Basis NOI as shown above. 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 GOV’s property level results of operations. GOV defines NOI as income from its rental of real estate less its property operating expenses. NOI excludes amortization of capitalized tenant improvement costs and leasing commissions because GOV records those amounts as depreciation and amortization. GOV defines Cash Basis NOI as NOI excluding non-cash straight line rent

adjustments, lease value amortization and non-cash amortization included in other operating expenses. GOV considers 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 GOV’s properties. GOV uses NOI and Cash Basis NOI to evaluate individual and company wide property level performance, and GOV believes that NOI and Cash Basis NOI provide useful information to investors regarding GOV’s 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 GOV’s 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 GOV’s liquidity. These measures should be considered in conjunction with net income and operating income as presented in GOV’s Condensed Consolidated Statements of Income. Other REITs and real estate companies may calculate NOI and Cash Basis NOI differently than GOV does.


(2)	Excludes one property (one building) classified as discontinued operations.

(3)

GOV reports rental income on a straight line basis over the terms of the respective leases; as a result, 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 GOV by its tenants, as well as the net effect of non-cash amortization of intangible lease assets and liabilities.


(4)	GOV recorded a liability for the amount by which the estimated fair value for accounting purposes exceeded the price GOV paid for its investment in RMR common stock in June 2015. A portion of this liability is being amortized on a straight line basis through December 31, 2035 as a reduction to property management fees, which are included in property operating expenses.


(5)	For the three months ended March 31, 2017 and 2016, same property NOI and same property cash basis NOI are based on properties GOV owned as of March 31, 2017 and which it owned continuously since January 1, 2016, excluding one property (one building) classified as discontinued operations.
