CALCULATION AND RECONCILIATION OF FUNDS FROM OPERATIONS (FFO) AND (FFO) OF FUNDS FROM OPERATIONS AND RECONCILIATION CALCULATION Senior Housing Properties Trust 28 Supplemental Operating and Financial Data, June 30, 2018

DEFINITIONS OF CERTAIN NON-GAAP FINANCIAL MEASURES NOI and Cash Basis NOI 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 calculate NOI and Cash Basis NOI as shown on page 22. We define NOI as income from our real estate less our property operating expenses. NOI excludes amortization of capitalized tenant improvement costs and leasing commissions that we record as depreciation and amortization. We define Cash Basis NOI as NOI excluding non-cash straight line rent adjustments, lease value amortization, lease termination fee amortization, if any, and non-cash amortization included in property 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 these measures 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 alternatives to net income, net income attributable to common shareholders or operating income as indicators of our operating performance or as measures of our liquidity. These measures should be considered in conjunction with net income, net income attributable to common shareholders and operating income as presented in our condensed consolidated statements of income. Other real estate companies and REITs may calculate NOI and Cash Basis NOI differently than we do. EBITDA and Adjusted EBITDA We calculate EBITDA and Adjusted EBITDA as shown on page 27. We consider EBITDA and Adjusted EBITDA to be appropriate supplemental measures of our operating performance, along with net income, net income attributable to common shareholders 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, net income attributable to common shareholders or operating income as indicators of operating performance or as measures of our liquidity. These measures should be considered in conjunction with net income, net income attributable to common shareholders and operating income as presented in our condensed consolidated statements of income. Other real estate companies and REITs may calculate EBITDA and Adjusted EBITDA differently than we do. FFO and Normalized FFO Attributable to Common Shareholders We calculate FFO attributable to common shareholders and Normalized FFO attributable to common shareholders as shown on page 28. FFO attributable to common shareholders is calculated on the basis defined by the National Association of Real Estate Investment Trusts, or Nareit, which is net income attributable to common shareholders, calculated in accordance with GAAP, excluding any gain or loss on sale of real estate and loss on impairment of real estate assets, if any, plus real estate depreciation and amortization and the difference between net income attributable to common shareholders and FFO attributable to noncontrolling interest, as well as certain other adjustments currently not applicable to us. Our calculation of Normalized FFO attributable to common shareholders differs from Nareit's definition of FFO because 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 and certain other transaction related costs expensed under GAAP such as legal and professional fees associated with our acquisition and disposition activities, gains and losses on early extinguishment of debt, if any, unrealized gains and losses on equity securities, net, if any, and Normalized FFO from noncontrolling interest, net of FFO, if any. We consider FFO attributable to common shareholders and Normalized FFO attributable to common shareholders to be appropriate supplemental measures of operating performance for a REIT, along with net income, net income attributable to common shareholders and operating income. We believe that FFO attributable to common shareholders and Normalized FFO attributable to common shareholders provide useful information to investors, because by excluding the effects of certain historical amounts, such as depreciation and amortization expense, FFO attributable to common shareholders and Normalized FFO attributable to common shareholders may facilitate a comparison of our operating performance between periods and with other REITs. FFO attributable to common shareholders and Normalized FFO attributable to common shareholders 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 revolving credit facility and term loan agreements and our public debt DEFINITIONS OF CERTAIN NON-GAAP FINANCIAL MEASURES FINANCIAL NON-GAAP DEFINITIONS OF CERTAIN covenants, the availability to us of debt and equity capital, our expectation of our future capital requirements and operating performance and our expected needs for and availability of cash to pay our obligations. FFO attributable to common shareholders and Normalized FFO attributable to common shareholders 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 common shareholders or operating income as indicators of our operating performance or as measures of our liquidity. These measures should be considered in conjunction with net income, net income attributable to common shareholders and operating income as presented in our condensed consolidated statements of income. Other real estate companies and REITs may calculate FFO and Normalized FFO differently than we do. Senior Housing Properties Trust 29 Supplemental Operating and Financial Data, June 30, 2018
