SENIOR HOUSING PROPERTIES TRUST

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(dollar amounts in thousands, except per share data or as otherwise stated)

Note 1. Basis of Presentation

The accompanying condensed consolidated financial statements of Senior Housing Properties Trust and its subsidiaries, or we, us, or our, are unaudited. Certain information and disclosures required by U.S. generally accepted accounting principles, or GAAP, for complete financial statements have been condensed or omitted. We believe the disclosures made are adequate to make the information presented not misleading. However, the accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes contained in our Annual Report on Form 10-K for the year ended December 31, 201 4, or our Annual Report. In the opinion of our management, all adjustments, which include only normal recurring adjustments, considered necessary for a fair presentation have been included. All intercompany transactions and balances with or among our consolidated subsidiaries have been eliminated. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year. Reclassifications have been made to the prior year’s financial statements to conform to the current year’s presentation. These reclassifications were made to conform the prior periods’ rental income, property operating expenses, discontinued operations, general and administrative expenses, interest and other income and impairment of assets to the current classification. These reclassifications had no effect on net income or shareholders’ equity.

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect reported amounts. Actual results could differ from those estimates. Significant estimates in our condensed consolidated financial statements include purchase price allocations, useful lives of fixed assets and impairment of real estate and intangible assets.

Note 2. Recent Accounting Pronouncements

In February 2015, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update No. 2015-02, Consolidation. Among other things, t his update changes how an entity determine s the primary beneficiary of a variable interest entity. This update is effective for interim and annual periods beginning after December 15, 2015, with early adoption permitted. The implementation of this update is not expected to cause any significant changes to our condensed consolidated financial statements.

In April 2015, the FASB issued Accounting Standards Update No. 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated debt liability. This update is effective for interim and annual reporting periods beginning after December 15, 2015 and requires retrospective application. The implementation of this update is not expected to cause any material changes to our consolidated financial statements other than the reclassification of debt issuance costs from assets to liabilities on our condensed c onsolidated b alance s heets.

Note 3. Real Estate Properties

At March 31, 201 5, we owned 3 92 properties (41 9 buildings) located in 3 9 states and Washington, D.C. We have accounted, or expect to account for, the following acquisitions as business combinations unless otherwise noted.

MOB Acquisitions:

In January 201 5, we acquired 23 propert ies (23 building s) leased to medical providers, medical related businesses, clinics and biotech laboratory tenants, or MOB s, for approximately $539,000, including the assumption of approximately $29,955 of mortgage debt with a weighted average interest rate of 4.7 3%, and excluding closing costs. T hese MOB s are located in 12 states and include approximately 2,170,000 square feet of leasable space. We funded this acquisition using cash on hand and borrowings under our revolving credit facility. The 23 properties were purchased

from Select Income REIT, or SIR, in connection with the acquisition by SIR of Cole Corporate Income Trust, Inc., or CCIT. See Note 10 for further information regarding this transaction.

| (1) |  | These amounts include the cash we paid plus the debt we assumed, if any, as well as other settlement adjustments with respect to the acquisitions, but exclude closing costs. The allocation of the purchase price of our acquisitions shown above is based upon preliminary estimates of the fair value of assets acquired and liabilities assumed. Consequently, amounts preliminarily allocated to assets acquired and liabilities assumed may change from those used in these condensed consolidated financial statements.

Senior Living Communit y Acquisitions:

In December 2014, we entered into a purchase agreement to acquire 38 senior living communities with 3,466 living units located in 16 states for $790,000, excluding closing costs, and including the assumption of approximately $153,000 of mortgage debt with a weighted average interest rate of 4.77%. These communities include an aggregate of 3,466 living units, comprised of 826 independent living units, 1,860 assisted living units, 744 memory care units and 36 skilled nursing facility units. On May 1, 2015, we completed the acquisition of 37 of these senior living communities with 3,379 living units for approximately $762,611, excluding closing costs, and we amended the purchase agreement to accommodate a delayed closing of the remaining senior living community with 87 living units. The acquisition of the one remaining senior living community is subject to various conditions; accordingly, we can provide no assurance that we will acquire this community, that the acquisition will not be delayed further or that the terms will not change. Nineteen of the 38 communities, with 2,190 living units, including the one community that we have not yet acquired, are leased to seven senior living operators. The 19 remaining communities, with 1,276 living units, were acquired using taxable real estate investment trust, or REIT, subsidiary, or TRS, structures. Pursuant to pre-existing management agreements, w e paid fees of $975 and terminated the se agreements for 14 of the 19 communities, with 881 living units, and entered into management agreements with Five Star Quality Care, Inc., or Five Star, to manage these communities. See Note 10 for further information regarding these management agreements with Five Star. The remaining five communiti es, with 395 living units, continue to be managed by the current third party senior living operator. As of the date of this filing, the purchase price allocation for this acquisition is pending.

In April 2015, we entered into an agreement to acquire one senior living community with 40 private pay independent living units located in Cumming, GA, for approximately $9,750, excluding closing costs. We intend to acquire this community using a TRS structure and we expect to enter into a management agreement with Five Star to manage this community. This senior living community is adjacent to another community that we own which is managed by Five Star. This acquisition is subject to various conditions; accordingly, we can provide no assurance that we will purchase this property, that the acquisition and related expected management arrangement with Five Star will not be delayed or that the terms will not change.

Impairment:

We periodically evaluate our properties for impairments. Impairment indicators may include declining tenant occupancy, weak or declining tenant profitability, cash flow or liquidity, our decision to dispose of an asset before the end of its estimated useful life, and legislative, market or industry changes that could permanently reduce the value of a property.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(dollar amounts in thousands, except per share data or as otherwise stated)

If indicators of impairment are present, we evaluate the carrying value of the affected property by comparing it to the expected future undiscounted net cash flows to be generated from that property. If the sum of these expected future net cash flows is less than the carrying value, we reduce the net carrying value of the property to its estimated fair value.

Discontinued Operations and Properties Held for Sale:

As of March 31, 201 5, we had three senior living communities with 19 2 living units and one MOB (four buildings) with 323,541 square feet categorized as properties held for sale. The se four properties are included in other assets in our condensed consolidated balance sheets and have a net book value (after impairment) of approximately $3,145 at March 31, 2015. We classify all properties as held for sale in our condensed consolidated balance sheets that meet the applicable criteria for that treatment as set forth in the Property, Plant and Equipment Topic of the FASB Accounting Standards Codification, or the Codification.

Results of operations for properties sold or held for sale are included in discontinued operations in our condensed consolidated statements of operations once the criteria for discontinued operations in the Presentation of Financial Statements Topic of the Codification are met. The senior living properties which we are or were offering for sale as of the applicable periods do not meet the criteria for discontinued operations as they are included within combination leases with other properties that we expect to continue leasing. We had one MOB (four buildings) and four MOBs (seven buildings), classified in discontinued operations as of March 31, 2015 and 2014, respectively. Summarized incom e statement information for these MOBs that meet the criteria for inclusion in discontinued operations is as follows:

|  | Three Months Ended |
|  | March 31, |
|  | 2015 |  | 2014 |
Rental income |  | $ | 32 |  | $ | 2,294 |
Property operating expenses |  |  | (273) |  |  | (994) |
(Loss) income from discontinued operations |  | $ | (241) |  | $ | 1,300 |

Dispositions:

In February 2015, we sold one vacant senior living community located in Pennsylvania for a sale price of $250, excluding closing costs. In April 2015, we sold the remaining held for sale MOB (four buildings) for a sale price of $1,500, excluding closing costs. Any adjustments to net book value related to this sale will be recognized in the second quarter of 2015 when all of the costs of the sale are known.

Note 4. Unrealized Gain / Loss on Investments

As of March 31, 2015, we owned 250,000 common shares of Equity Commonwealth (formerly known as CommonWealth REIT), or EQC, and 4,235,000 common shares of Five Star which are carried at fair market value in other assets on our condensed consolidated balance sheets. Cumulative other comprehensive income shown in our condensed consolidated balance sheets includes the net unrealized gain or loss on investments determined as the net difference between the value at quoted market prices of our EQC and Five Star shares as of March 31, 2015 ($2 6.55 and $4.44 per share, respectively) and our weighted average costs at the time we acquired these shares, as adjusted to reflect any share splits or combinations ($26.00 and $3.36 per share, respectively).

Note 5. Indebtedness

Our principal debt obligations at March 31, 2015 were: (1) six public issuances of senior unsecured notes, including: (a) $250,000 principal amount at an annual interest rate of 4.30% due 2016, (b) $400,000 principal amount at an annual interest rate of 3.25% due 2019, (c) $200,000 principal amount at an annual interest rate of 6.75% due 2020,

(d) $300,000 principal amount at an annual interest rate of 6.75% due 2021, (e) $250,000 principal amount at an annual interest rate of 4.75% due 2024 and (f) $350,000 principal amount at an annual interest rate of 5.625% due 2042; (2) our $350,000 principal amount term loan; and (3) $609,032 aggregate principal amount of mortgages secured by 4 6 of our properties (48 buildings) with maturity dates from 2015 to 2043. The 4 6 mortgaged properties (48 buildings) had a carrying value of $776,980 at March 31, 2015. We also had two properties subject to capital leases totaling $1 2,621 at March 31, 2015; these two properties had a carrying value of $18,095 at March 31, 2015. The capital leases expire in 2026.

We have a $750,000 unsecured revolving credit facility that is available for general business purposes, including acquisitions. The maturity date of our revolving credit facility is January 15, 2018 and, subject to the payment of an extension fee and meeting certain other conditions, we have an option to further extend the stated maturity date by an additional one year to January 15, 2019. The revolving credit facility agreement provides that we can borrow, repay and reborrow funds available under the revolving credit facility agreement until maturity, and no principal repayment is due until maturity. The revolving credit facility agreement includes a feature under which maximum borrowings under the facility may be increased to up to $1,500,000 in certain circumstances. The interest rate paid on borrowings under the revolving credit facility agreement is LIBOR plus a premium of 130 basis points, and the facility fee is 30 basis points per annum on the total amount of lending commitments. Both the interest rate premium and the facility fee are subject to adjustment based upon changes to our credit ratings. As of March 31, 2015, the interest rate payable on borrowings under our revolving credit facility was 1.47%, and the weighted average interest rate for borrowings under our revolving credit facility was 1.54% and 1.42% for the three months ended March 31, 2015 and 2014, respectively. As of March 31, 2015, we had no amounts outstanding and $750,000 available for borro wing by us, and as of May 5, 2015, we had $55 0,00 0 outstanding and $200,000 available for borrowing by us under our revolving credit facility.

In 2014, we entered into a term loan agreement pursuant to which we obtained a $350,000 unsecured term loan. Our term loan matures on January 15, 2020, and is prepayable without penalty at any time. In addition, our term loan includes a feature under which maximum borrowings may be increased to up to $700,000 in certain circumstances. Our term loan bears interest at a rate of LIBOR plus a premium of 140 basis points that is subject to adjustment based upon changes to our credit ratings. As of March 31, 2015, the interest rate payable for amounts outstanding under our term loan was 1.5 7%. The weighted average annual interest rate for amounts outstanding on our term loan was 1.5 9% for the three months ended March 31, 2015.

Our revolving credit facility and term loan agreements provide for the acceleration of payment of all amounts outstanding upon the occurrence and continuation of certain events of default, including a change of control of us, which includes Reit Management & Research LLC, or RMR, ceasing to act as our business manager and property manager.

In December 2014, we entered an agreement to acquire the 38 senior living communities d iscussed in Note 3 above. Simultaneous with entering this agreement, we received a bridge loan commitment for $700,000. In February 2015, we terminated the bridge loan commitment and we recognized a loss of $1,409 on extinguishment of debt in the first quarter of 2015 in connection with that termination. We acquired 37 of these 38 senior living communities in May 2015 and financed the acquisition using cash on hand, borrowings under our revolving credit facility and the assumption of approximately $1 39,181 of mortgage debt with a weighted average interest rate of 4.59%.

Our public debt indenture and its related supplements and our credit facility and term loan agreement s contain a number of financial and other covenants, including covenants that restrict our ability to incur indebtedness or to make distributions under certain circumstances and require us to maintain financial ratios. We believe we were in compliance with the terms and conditions of our public debt indenture and its supplements and our credit facility and term loan agreements at March 31, 2015.

In connection with two of the properties acquired in January 2015, discussed in Note 3 above, we assum ed $29,955 of mortgage debt, which we recorded at their aggregate fair value of $31,02 9. These two assumed mortgage notes ha ve a

contractual weighted average interest rate of 4.73% and mature in July 20 16 and October 2022. We determined the fair value of the assumed mortgage notes using a market approach based upon Level 3 inputs (significant other unobservable inputs) in the fair value hierarchy.

In February 2015, we repaid a mortgage note that encumbered one of our properties that had a principal balance of $29,227 and a n interest rate of 6.02%.

In April 2015, we pre paid a mortgage note that encumbered one of our properties that had a principal balance of $6,2 74 and an interest rate of 5.81%.

Note 6. Shareholders’ Equity

In February 2015, we issued 31,050,000 common shares in a public offering, raising net proceeds of approximately $659,750 after underwriting discounts and expenses. We used the net proceeds from this offering to repay borrowings outstanding under our revolving credit facility an d for general business purposes.

On February 2 4, 201 5, we paid a distribution to common shareholders of $0.39 per share, or approximately $79,530, that was declared on January 12, 201 5 and was payable to sha reholders of record on January 2 3, 201 5.

On April 13, 2015, we declared a distribution payable to common shareholders of record on April 24, 2015, of $0.39 per share, or approximately $91,655. We expect to pay this distribution on or about May 21, 201 5 using cash on hand and borrowings under our revolving credit facility.

During the three months ended March 31, 201 5 and the period from April 1, 201 5 to May 5, 201 5, we issued 36,610 and 15,431, respectively, of our common shares to RMR as part of the business management fee payable by us under our business management agreement. See Note 10 for further information regarding this agreement.

Note 7. Fair Value of Assets and Liabilities

The following table presents certain of our assets and liabilities that are measured at fair value on a recurring and non recurring basis at March 31, 2015 categorized by the level of inputs used in the valuation of each asset or liability.

|  |  |  |  | Quoted Prices in |  | Significant |  | Significant |
|  |  |  |  | Active Markets for |  | Other |  | Unobservable |
|  |  |  |  | Identical Assets |  | Observable Inputs |  | Inputs |
Description |  | Total |  | (Level 1) |  | (Level 2) |  | (Level 3) |
Assets held for sale(1) |  | $ | 3,145 |  | $ | — |  | $ | — |  | $ | 3,145 |
Investments in available for sale securities(2) |  | $ | 25,441 |  | $ | 25,441 |  | $ | — |  | $ | — |

| (1) |  | Assets held for sale consist of four of our properties (seven buildings) that we expect to sell or have sold subsequent to March 31, 2015 that are reported at fair value less estimated costs to sell. We used offers to purchase these properties made by third parties or compar able sales transactions (Level 3 inputs) to determine the fair values of these properties. We have recorded cumulative impairments of approximately $11,365 to these properties in order to reduce their book value to fair value.

| (2) |  | Our investments in available for sale securities include our 250,000 common shares of EQC and 4,235,000 common shares of Five Star. The fair values of these shares are based up on quoted prices at March 31, 2015 in active markets (Level 1 inputs).

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(dollar amounts in thousands, except per share data or as otherwise stated)

We estimate the fair values of our senior unsecured notes using an average of the bid and ask price of our outstanding six issuances of senior notes (Level 1 inputs) on or about March 31, 2015. The fair values of these senior note obligations exceed their aggregate book values of $1,743,98 3 by $107,931 because these notes were trading at premiums to their face amounts.

We estimate the fair values of our secured debt by using discounted cash flow analyses and currently prevailing market terms as of the measurement date (Level 3 inputs). The fair value of our secured debt exceeds its book value of $609,032 by $6 6,837 because current market interest rates are lower than the market interest rates at the time we assumed the secured debt. Because Level 3 inputs are unobservable, our estimated fair value may differ materially from the actual fair value.

In addition to the assets and liabilities described in the above table and our senior unsecured notes and secured debt, our additional financial instruments include rents receivable, cash and cash equivalents, restricted cash and other unsecured debt. The fair values of these additional financial instruments approximate their carrying values at March 31, 2015 based upon their liquidity, short term maturity, variable rate pricing or our estimate of fair value using discounted cash flow analyses and prevailing interest rates.

Note 8. Segment Reporting

We have four operating segments, of which three are separately reportable operating segments: (i) triple net senior living communities that we lease to operators who provide short term and long term residential care and dining services for residents, (ii) managed senior living communities that provide short term and long term residential care and dining services for residents and (iii) MOBs. Our triple net and managed senior living communities include independent living communities, assisted living communities and skilled nursing facilities, or SNFs. Properties in the MOB segment include medical office, clinic and biotech laboratory buildings. The “All Other” category in the following table includes amounts

Five Star: As of March 31, 2015, we leased 180 senior living communities to Five Star. Five Star's total minimum annual rent payable to us as of March 31, 2015, was $191,007, excluding percentage rent. We recognized total re ntal income from Five Star of $47,691 and $47,506 for the three months ended March 31, 2015 and 2014, respectively. As of March 31, 2015 and December 31, 2014, our rents receivable from Five Star were $15,893 and $1 7,310, respectively, and those amounts are included in other assets in our condensed consolidated balance sheets. In April 2015 and 2014, we received estimated percentage rent payments from Five Star of $1,456 and $1,416 for the three months ended March 31, 2015 and 2014, respectively. We determine actual percentage rent due under our F ive Star leases annually and recognize any resulting amount as rental income at year end when all contingencies are met. During the three months ended March 31, 2015 and 2014, pursuant to the terms of our leases with Five Star, we purchased $4,550 and $8,614, respectively, of improvements made to properties leased to Five Star, and, as a result, the annual rent payable to us by Five Star increased by approximately $367 and $689, respectively.

In Februar y 2015, we and Five Star sold a vacant assisted living community located in Pennsylvania with 1 20 units for a sale price of $250; and, as a result of this sale, Five Star’s annual minimum rent payable to us decreased by $23 in accordance with the terms of the applicable lease.

As of March 31, 2015, Five Star managed 4 6 senior living communities for our account. Pursuant to our management agreements with Five Star, we incurred management fees of $2,523 and $2,425 for the three months ended March 31, 2015 and 2014, respectively, with respect to the communities Five Star manages. These amounts are included in property operating expenses in our condensed consolidated statements of income and comprehensive income.

I n connection with our acquisition of 37 senior living communities in May 2015 described in Note 3, w e terminated the pre-existing management agreements for 14 of these communities, with 881 living units, and entered into management agreements with Five Star to manage these communities for our account.

In April 2015, we entered into an agreement to acquire one senior living community with 40 private pay independent living units located in Cumming, GA, for approximately $9,750, excluding closing costs. We intend to acquire this community using a TRS structure and we expect to enter into a management agreement with Five Star to manage this community. This senior living community is adjacent to another community that we own which is managed by Five Star. Th is acquisition is subject to various conditions; accordingly, we can provide no assurance that we will purchase this property, that the acquisition and related expected management arrangement with Five Star will not be delayed or that the terms will not change.

Pursuant to the sublease agreement between one of our TRSs and D&R Yonkers LLC, D&R Yonkers LLC paid to us $752 and $730 in rent for the three months ended March 31, 2015 and 2014, respectively. D&R Yonkers LLC is owned by our officers in order to accommodate certain state licensing requirements. Five Star manages the senior living community to which the sublease agreement relates.

RMR: Pursuant to our business management agreement with RMR, we recognized business management fees of $8,869 and $6,682 for the three months ended March 31, 2015 and 2014, respectively. The business management fees we recognized for the 2014 and 2015 periods are included in general and administrative expenses in our condensed consolidated financial statements. In accordance with the terms of our business management agreement, we issued 39,467 of our common shares to RMR for the three months ended March 31, 2015, as payment for a portion of the base business management fee we recognized for that period.

Pursuant to our property management agreement with RMR, the aggregate property management and construction supervision fees we recognized were $2,438 and $1,638 for the three months ended March 31, 2015 and 2014, respectively. These amounts are included in property operating expenses or have been capitalized, as appropriate, in our condensed consolidated financial statements.

SIR: On January 29, 2015, we acquired from SIR, entities owning 23 MOBs that SIR acquired when its subsidiary merged with CCIT. Our purchase price for these 23 MOBs was approximately $539,000, including the assumption of approximately $29,955 of mortgage debt. These 23 MOBs contain approximately 2,170,000 square feet and are located in 12 states. As of March 31, 2015, $8,993 of amounts due from related persons included in other assets in our condensed consolidated balance sheet represented amounts owed to us from SIR related to working capital activity for th e 23 MOBs as of the sale date. This amoun t was paid to us in April 2015.

AIC: As of March 31, 2015, our investment in Affiliates Insurance Company, or AIC, an Indiana insurance company, had a carrying value of $6,944, which amount is included in other assets on our condensed consolidated balance sheet. We recognized income (loss) of $72 and ($97) related to our investment in AIC for the three months ended March 31, 2015 and 2014, respectively.

Note 11. Income Taxes

We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, and as such, are generally not subject to federal and most state income taxation on our operating income provided we distribute our taxable income to our shareholders and meet certain organization and operating requirements. We do, however, lease certain managed senior living communities to our wholly owned TRSs that, unlike most of our subsidiaries, file a separate consolidated federal corporate income tax return and are subject to federal and state income taxes. Our consolidated income tax provision includes the income tax provision related to the operations of our TRSs and certain state income taxes we incur despite our REIT status. During the three months ended March 31, 201 5 and 2014, we recognized income tax expense of $1 10 and $191, respectively.

Note 12. Weighted Average Per Common Share Amounts

We calculate basic earnings per common share by dividing net income by the weighted average number of common shares outstanding during the period. We calculate diluted earnings per common share by using the more dilutive of the two class method or the treasury stock method. Unvested share awards and other potentially dilutive common shares, including contingently issuable common shares under our business management agreement with RMR, if any, and the related impact on earnings, are considered when calculating diluted earnings per share. The following table provides a reconciliation of the weighted average number of common shares used in the calculation of basic and diluted earnings per share (in thousands):

|  | Three Months Ended March 31,
|  | 2015 |  | 2014
Weighted average common shares for basic earnings per share |  |  | 221,375 |  |  | 188,026
Effect of dilutive securities: unvested share awards |  |  | 22 |  |  | 19
Weighted average common shares for diluted earnings per share |  |  | 221,397 |  |  | 188,045

Note 1 3. Pro Forma Information

During the three months ended March 31, 201 5, we acquired 23 properties for an aggregate purchase price of $539,000, excluding closing costs, and including the assumption of $29,955 of mortgage debt with a weighted average interest rate of 4.73%. We recognized rental income and property operating expenses from this acquisition of $7,046 and $1,094, respectively, for the three months ended March 31, 2015. In February 2015, we sold 31,050,000 of our common shares in a public offering raising net proceeds of approximately $659,750 after underwriting discounts and expenses.

During 2014, we purchased two senior living communities and two MOBs (three bui ldings) for $1,204,393, excluding closing costs. We also assumed $15,630 of mortgage debt at a weighted average interest rate of 6.28% related to one of

our 2014 acquisitions. In April 2014, we issued 15,525,000 common shares in a public offering, raising net proceeds of approximately $322,807 after underwriting discounts and expenses. Also in April 2014, we sold $400,000 of 3.25% senior unsecured notes due 2019 and $250,000 of 4.75% senior unsecured notes due 2024, raising net proceeds of approximately $644,889 after underwriting discounts and expenses. In May 2014, we entered into a $350,000 term loan agreement, which bears interest at a rate of LIBOR plus a premium of 140 basis points.

The following table presents our pro forma results of operations for the three months ended March 31, 2015 and 2014 as if the acquisition of the 3 7 senior living communities described in Note 3 and the 2015 acquisition and financing activities described in the two preceding paragraphs had occurred on January 1, 201 4, and the 2014 acquisition and financing activities described in the two paragraphs above had occurred on January 1, 2013. This pro forma data is not necessarily indicative of what our actual results of operations would have been for the periods presented, nor does it represent the results of operations for any future period. Differences could result from numerous factors, including future changes in our portfolio of investments, changes in interest rates, changes in our capital structure, changes in property level operating expenses, changes in property level revenues, including rents expected to be received on our existing leases or leases we may enter into during and after 201 5, and for other reasons.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion should be read in conjunction with our condensed consolidated financial statements and notes thereto included in this Quarterly Report on Form 10-Q and with our Annual Report. We are a REIT organized under Maryland law. At March 31, 201 5, we owned 392 properties (419 buildings) located in 3 9 states and Washington, D.C., including four propert ies (seven buildings) classified as held for sale. Of the properties classified as held for sale, one property (four buildings) is included in discontinued operations at March 31, 2015. On that date, the undepreciated carrying value of our properties, net of impairment losses, was $6.7 billion, excluding properties classified as held for sale. As of March 31, 2015, 9 7% of our net operating income, or NOI, came from properties where a majority of the charges are paid from our residents’ and tenants’ private resources.

If the number of living units included in our TRS leases were included in the foregoing table, the percent of total living units / beds expiring would be: 201 5 — 0.4%, 201 6 — 0.0%; 201 7 — 0.0%; 201 8 — 5.2%; 201 9 — 0.6%; 20 20 — 0.0%; 2021 — 1.2%; 202 2 — 0.0%; 202 3 — 0.0% and thereafter — 92.6%.

During the three months ended March 31, 201 5, we entered into MOB lease renewals for 349,000 square feet and new leases for 30,000 square feet. The weighted average annual rental rate for leases entered into during the quarter was $20.47 per square foot, and these rental rates were, on a weighted average basis, 8.8% above previous rents charged for the same space. Average lease terms for leases entered into during the first quarter of 201 5 were 3.9 years based on square footage. Commitments for tenant improvement, leasing commission costs and concessions for leases we entered into during the first quarter of 201 5 totaled $4.6 million, or $12.11 per square foot on average (approximately $3.07 per square foot per year of the lease term).

RESULTS OF OPERATIONS (dollars and square feet in thousands, unless otherwise noted)

We have four operating segments, of which three are separately reportable operating segments: (i) triple net senior living communities that provide short term and long term residential care and dining services for residents, (ii) managed senior living communities that provide short term and long term residential care and dining services for

Except as noted below under “Rental income”, we have not included a discussion and analysis of the results of our comparable properties data for the triple net leased senior living communities segment as we believe that a comparison of the results for our comparable properties for our triple net leased senior living communities segment is generally consistent from quarter to quarter and a separate, comparable properties comparison is not meaningful.

Rental income. Rental income increased primarily due to increased rents resulting from our purchase of approximately $30,354 of improvements made to our properties that are leased by Five Star since January 1, 2014, partially offset by the sale of seven senior living communities since January 1, 2014. Rental income increased year over year on a comparable property basis by $747, primarily as a result of our improvement purchases at certain of the 21 4 communities we have owned continu ously since J anuary 1, 201 4 and the resulting increased rent, pursuant to the terms of the leases.

Net operating income. NOI increased because of the changes in rental income described above. We do not incur property operating expenses at our triple net leased senior living communities, as these expenses are paid by our tenants. Accordingly, rental income is the same as NOI. The reconciliation of NOI to net income for our triple net leased senior living communities segment is shown in the table above. Our definition of NOI and our reconciliation of consolidated NOI to net income are included below under the heading “Non-GAAP Financial Measures”.

Depreciation expense. Depreciation expense recognized in this segment decreased as a result of the sale of seven senior living communities since January 1, 2014. This decrease was partially offset by our purchase of improvements made to our properties that are leased by Five Star since January 1, 201 4.

Interest expense. Interest expense for our triple net leased senior living communities arises from mortgage debt secured by certain of these properties. The decrease in interest expense is the result of the October 2014 prepayment of a $14,700 loan incurred in connection with certain revenue bonds that had an interest rate of 5.875%, and the October 2014 prepayment of one mortgage note with a principal balance of $11,926 and an interest rate of 6.25%, as well as the regularly scheduled amortization of our mortgage debt.

Gain on sale of properties. Gain on sale of properties is a result of the sale of one senior living community in January 2014.

Residents fees and services. Residents fees and services are the revenues earned at our managed senior living communities. We recognize these revenues as services are provided. The increase in residents fees and services primarily relates to the acquisition of two managed senior living communities in December 2014 as well as an increase in average monthly rate in the first quarter of 2015.

Property operating expenses. Property operating expenses include expenses incurred at our managed senior living communities and they consist of management fees, real estate taxes, utility expense, insurance, salaries and benefits of property level personnel, repairs and maintenance expense, cleaning expense and other direct costs of these operating properties. The increase in property operating expenses primarily relates to the acquisition of two managed senior living communities in December 2014.

Net operating income. NOI increased because of the changes in residents fees and services and property operating expenses described above. The reconciliation of NOI to net income for our managed senior living communities segment is shown in the table above. Our definition of NOI and our reconciliation of consolidated NOI to net income are included below under the heading “Non-GAAP Financial Measures”.

Depreciation expense. Depreciation expense includes the depreciation of owned property and equipment as well as the amortization expense of in-place resident agreements assumed upon the acquisition of a community. Depreciation expense increased primarily as a result of the acquisition of two managed senior living communities in December 2014. This increase was slightly offset by a decrease in amortization expense noted above as the result of a number of resident agreement s being fully amortized in 2014.

Interest Expense. Interest expense for our managed senior living communities arises from mortgage debt secured by certain of these properties. Interest expense decreased as a result of the repayment of t hree loans in June and December 2014 that had a total principal balance of $47,115 and a weighted average interest rate of 6.0%, the repayment of a loan

Residents fees and services. We recognize residents fees and services as services are provided. Our residents fees and services increased year over year on a comparable property basis primarily because of an in crease in the average daily rate at the 44 communities we have owned continuously since January 1, 201 4.

Property operating expenses. Property operat ing expenses consist of management fees, real estate taxes, utility expense, insurance, salaries and benefit costs of property level personnel, repairs and maintenance expense, cleaning expense and other direct costs of operating properties. Property operating expenses de creased principally because of slight de creases in utili ty expenses, real estate taxes and other direct costs of operating properties.

Net operating income. The increase in NOI reflects the net changes in residents fees and services less the property operating expenses described above. The reconciliation of NOI to net income for our managed senior living communities segment, comparable properties, is shown in the table above. Our definition of NOI and our consolidated reconciliation of NOI to net income are included below in “Non-GAAP Financial Measures”.

Depreciation expense. Depreciation expense includes the depreciation of owned property and equipment as well as the amortization expense of in-place resident agreements assumed upon the acquisition of a community. A number of these resident agreements were fully amortized in 2014, resulting in a decrease in depreciation expense in the first quarter of 2015. This decrease was partially offset by an increase in depreciation expense resulting from our purchase of improvements at these properties.

Interest expense. Interest expense for our managed senior living communities arises from mortgage debt secured by certain of these properties. Interest expense decreased as a result of the repayment of three loans in June and December 2014 that had a total principal balance of $47,115 and a weighted average interest rate of 6.0%, the repayment of a loan in February 2015 that had a principal balance of $29,227 and an interest rate of 6.0%, as well as regularly scheduled amortization of our mortgage debt.

Interest expense. Interest expense for our MOBs arises from mortgage debt secured by certain of these properties. The increase in interest expense is the result of our assumption of $45,585 of mortgage debt in connection with our acquisition of three MOB s (three buildings) since J anuary 1, 201 4 with a weighted average interest rate of 5.3%, partially offset by the regularly scheduled amortization of our mortgage debt.

(Loss) i ncome from discontinued operations. Loss from discontinued operations for the three months ended March 31, 2015 relates to the one MOB (four buildings) which was majority vacant during the period classified as held for sale as of March 31, 201 5. The loss also resulted from the decline in offsetting income primarily due to the sale of t hree MOBs (t hree buildings) during the second and third quarter s of 2014.

Impairment of assets from discontinued operations. During the three months ended March 31, 2014, we recorded impairment of assets charges of $721 to reduce the carrying value of two of our MOBs (five buildings) to their estimated sales prices.

Rental income. Rental income decreased as a result of a reduction in same store occupancy from 95.0% at March 31, 2014 to 94.6% at March 31, 2015, as well as several lease renewals at lower rental rates. Rental income includes non-cash straight line rent adjustments totaling $1,120 and $1,478 and net amortization of approximately $(829) and $(777) of above and below market lease adjustments for the three months ended March 31, 201 5 and 201 4, respectively.

Property operating expenses. Property operating expenses consist of property management fees, real estate taxes, utility expense, salaries and benefit costs of property level personnel, repairs and maintenance expense, cleaning expense and other direct costs of operating properties. Property operating costs increased principally because of increases in salaries and benefits, landscaping (which includes snow removal), real estate taxes and other direct costs of operating properties. These expenses were partially offset by a decrease in utilities, resulting from a decrease in heating oil costs in the first quarter of 2015 compared to the first quarter of 2014.

Net operating income. NOI reflects the net changes in rental income and property operating expenses described above. The reconciliation of NOI to net income for our MOB segment for comparable properties is shown in the table above. Our definition of NOI and our reconciliation of consolidated NOI to net income are included below under the heading “Non-GAAP Financial Measures”.

Depreciation / amortization expense. Depreciation / amortization expense slightly decreased primarily because of a reduction in amortization of acquired in place real estate leases that we amortize over the respective lease terms, partially offset by an increase in the amortization of leasing costs and depreciation expense on fixed assets.

Interest expense. Interest expense for our MOBs arises from mortgage debt secured by certain of these properties. The slight decrease in interest expense is the result of the regularly scheduled amortization of our mortgage debt.

| (1) |  | All other operations includes our wellness center operations that we do not consider a significant, separately reportable segment of our business, corporate business activities, and operating expenses that are not attributable to a specific reportable segment.

Rental income. Rental income increased due to scheduled rent increases at certain of our wellness centers. Rental income includes non-cash straight line rent adjustme nts totaling approximately $138 in both the three months ended March 31, 201 5 and 201 4. Rental income also includes net amortization of approximately $55 of acquired real estate leases and obligations in both the three months ended March 31, 2015 and 2014.

Depreciation expense. Depreciation expense remained consistent as we did not make any wellness center acquisitions or other capital improvements in this segment for the three months ended March 31, 2015 and 2014 and we generally depreciate our long lived wellness center assets on a straight line basis.

General and administrative expense. General and administrative expenses consist of fees and expenses of our trustees, fees paid to RMR under our business management agreement, equity compensation expense, legal and accounting fees and other costs relating to our status as a publicly owned company. General and administrative expenses increased principally as a result of property acquisitions made since April 1, 201 4.

Acquisition related costs. Acquisition related costs represent legal and due diligence costs incurred in connection with our acquisition activity during the three months ended March 31, 2015 and 2014. Acquisition related costs in creased as a result of our acquisition of 23 MOBs in January 2015.

Interest and other income. The decrease in interest and other income is primarily a result of less dividend income f rom our shares of EQC.

Interest expense. Interest expense increased due to our issuance of $400,000 of 3.25% senior unsecured notes and $250,000 of 4.75% senior unsecured notes in April 2014 as well as our May 2014 term loan borrowing of $350,000 at LIBOR plus 140 basis points.

Loss on extinguishment of debt. In December 2014, we entered an agreement to acquire 38 senior living communities. Simultaneous with entering this agreement, we received a bridge loan commitment for $700,000. In February 2015, we terminated the bridge loan commitment and recognized a loss of $1,409 on extinguishment of debt in the first quarter of 2015.

Equity in earnings (losses) of an investee. Equity in earnings of an investee represents our proportionate share of earnings from AIC.

Non-GAAP Financial Measures (dollars in thousands, except per share amounts)

We provide below calculations of our funds from operations, or FFO, Normalize d FFO and NOI for the three months ended March 31, 201 5 and 201 4. These measures should be considered in conjunction with net income, operating income and cash flow from operating activities as presented in our condensed consolidated statements of income and comprehensive income and condensed consolidated statements of cash flows. These measures do not represent cash generated by operating activities in accordance with GAAP and should not be considered as alternatives to net income, 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. Other REITs and real estate companies may calculate FFO, Normalized FFO or NOI differently than we do.

Funds From Operations and Normalized Funds From Operations

We calculate FFO and Normalized FFO as shown below. 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, excluding any gain or loss on sale of properties and impairment of real estate assets, plus real estate depreciation and amortization, 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 estimated percentage rent in the period to which we estimate that it relates rather than when it is recognized as income in accordance with GAAP, include estimated business management incentive fees, if any, only in the fourth quarter versus the quarter they are recognized as expense in accordance with GAAP and exclude acquisition related costs, gain or loss on early extinguishment of debt, gain or loss on lease terminations and loss on impairment of intangible assets, if any. We consider FFO and Normalized FFO to be appropriate measures of operating performance for a REIT, along with net income, 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. Other factors include, but are not limited to, requirements to maintain our status as a REIT, limitations in our revolving credit facility agreement, term loan agreement and public debt covenants, the availability of debt and equity capital, our expectation of our future capital requirements and operating performance, and our expected needs and availability of cash to pay our obligations.

| (1) |  | In calculating net income in accordance with GAAP, we recognize percentage rental income received for the first, second and third quarters in the fourth quarter, which is when all contingencies are met and the income is earned. Although we defer recognition of this revenue until the fourth quarter for purposes of calculating net income, we include these estimated amounts in our calculation of Normalized FFO for each quarter of the year. The fourth quarter Normalized FFO calculation excludes the amounts included during the first three quarters.

Property Net Operating Income (NOI)

The calculation of NOI excludes certain components of net income in order to provide results that are more closely related to our properties’ results of operations. We calculate NOI as shown below. 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. We consider NOI to be an appropriate supplemental measure to net income because it may help both investors and management to understand the operations of our properties. We use NOI internally to evaluate individual and company wide property level performance, and we believe that NOI provides useful information to investors regarding our results of operations because it reflects 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.

LIQUIDITY AND CAPITAL RESOURCES

Rental income revenues and residents fees and services revenues from our leased and managed properties are our principal sources of funds to pay operating expenses, debt service and distributions to shareholders. We believe that our operating cash flow will be sufficient to meet our operating expenses and debt service and pay distributions on our shares for the next 12 months and for the foreseeable future thereafter. Our future cash flows from operating activities will depend primarily upon our ability to:

| · |  | maintain or improve the occupancy of, and the rent rates at, our properties;

| · |  | control operating cost increases; and

| · |  | purchase additional properties which produce cash flows in excess of our cost of acquisition capital and property operating expenses.

Our Operating Liquidity and Resources

We generally receive minimum rents monthly or quarterly from our tenants, we receive percentage rents from our senior living community tenants monthly, quarterly or annually and we receive residents fees and services revenues, net of expenses, from our managed senior living communities monthly. Our changes in cash flows for the three months ended March 31, 2015 compared to the three months ended March 31, 2014 were as follows: (i) cash pr ovided by operating activities increased from $90.1 million in 201 4 to $104.1 million in 201 5; (ii) cash used for investing activities increased from $64.8 million in 201 4 to $521.1 m illion in 201 5; and (iii) cash flows from finan cing activities increased

28

Table of Contents

from $31.6 million of cash used in financing activities in 201 4 to $467.2 million of cash provided by financing activities in 201 5.

The increase in cash provided by operating activities for the three months ended March 31, 2015 compared to the prior year was due primarily to increased operating cash flow from our acquisitions after April 1, 2014. The increase in cash used in investing activities for the three months ended March 31, 2015 compared to the prior year was due primarily to our acquisition of 23 MOBs (23 buildings) in January 201 5 for an aggregate purchase price of $539.0 m illi on, excluding acquisition costs and including mortgage debt assumed of $30.0 million. We did not acquire any properties in the first quarter of 2014, and our cash used for investing activit ies was primarily a $50.0 million deposit related to one MOB (two buildings) that we acquired in May 2014. The increase in cash provided by financing activities for the three months ended March 31, 2015 compared to the prior year was due primari ly to our public equity offering in February 201 5 to fund the acquisition of 23 MOBs (23 buildings) described above.

Our Investment and Financing Liquidity and Resources

As of March 3 1, 201 5, we had $77.8 million of cash and cash equivalents and $750.0 million available to borrow under our revolving credit facility. We expect to use cash balances, borrowings under our revolving credit facility, net proceeds from offerings of equity or debt securities, cash flow from our operations and possible assumption of mortgage debt on acquired properties to fund our operations, debt repayments, distributions, future property acquisitions, expenditures related to the repair, maintenance or renovation of our properties and other general business purposes. We believe such amounts will be sufficient to fund these activities for the next 12 months and the foreseeable future thereafter.

In order to fund acquisitions and to meet cash needs that may result from timing differences between our receipts of rents and our desire or need to make distributions or pay operating or capital expenses, we maintain a $750.0 million unsecured revolving credit facility with a group of institutional lenders. The maturity date of our revolving credit facility is January 15, 2018 and, subject to the payment of an extension fee and meeting certain other conditions, we have an option to extend the stated maturity date of our revolving credit facility by one year to January 15, 2019. In addition, the credit agreement governing our revolving credit facility includes a feature under which the maximum borrowing availability under the facility may be increased to up to $1.5 billion in certain circumstances. Borrowings under our revolving credit facility bear interest at LIBOR plus a premium, which was 130 basis points as of March 31, 201 5. We also pay a facility fee of 30 basis points per annum on the total amount of lending commitments under our revolving credit facility. Both the interest rate premium and the facility fee are subject to adjustment based upon changes to our credit ratings. We can borrow, repay and reborrow funds available under our revolving credit facility until maturity, and no principal repayment is due until maturity. As of March 31, 201 5, the interest rate payable on borrowings under our revolving credit facility was 1.4 7%. As of March 31, 2015 and May 5, 2015, we had no amounts and $550.0 million outstanding under our revolving credit facility, respectively. We may also assume outstanding mortgage debt in connection with our acquisitions of properties or place new mortgages on properties we own.

When significant amounts are outstanding under our revolving credit facility or as the maturity dates of our revolving credit facility and term debts approach, we intend to explore alternatives for the repayment of amounts due. Such alternatives may include incurring additional debt and issuing new equity securities. We currently have an effective shelf registration statement that allows us to issue public securities on an expedited basis, but it does not assure that there will be buyers for such securities.

In February 2015, we repaid a mortgage note for approximately $29.2 million that had a maturity date in March 2015 with an interest rate of 6.02% encumbering one of our properties. In April 2015, we prepaid a mortgage note for approximately $6.3 million that had a maturity date in October 2015 with an interest rate of 5.81%.

In January 2015, we acquired 23 MOBs (23 buildings), for approximately $539.0 million, including the assumption of approximately $30.0 million of mortgage debt with a weighted average interest rate of 4.73%. The MOBs contain approximately 2.2 million square feet and are located in 12 state s. The 23 properties were purchased from SIR in connection with the acquisition by SIR of CCIT. We used borrowings under our revolving credit facility to fund the cash payment of this acquisition.

Table of Contents

In December 2014, we entered into a purchase agreement to acquire 38 senior living communities with 3,466 living units located in 16 states for $790.0 million, excluding closing costs. In May 2015, we completed the acquisition of 37 of these senior living communities with 3,379 living units for $762.6 million, and we amended the purchase agreement to accommodate a delayed closing of the one remaining senior living community with 87 living units. We financed this acquisition using cash on hand, borrowings under our revolving credit facility and by assuming approximately $1 39.2 million of mortgage debt with a weigh ted average interest rate of 4.59%. The acquisition of the remaining senior living community is expected to close by year end 2015, but this acquisition is subject to various conditions; accordingly, we can provide no assurance that we will acquire this community, that the acquisition will not be delayed further or that the terms will not change.

In April 2015, we entered into an agreement to acquire one senior living community with 40 private pay independent living units located in Cumming, GA, for approximately $9.8 million, excluding closing costs. We intend to finance this acquisition using cash on hand and borrowings under our revolving credit facility. Th is acquisition is subject to various conditions; accordingly, we can provide no assurance that we will purchase this property, that the acquisition will not be delayed or that the terms will not change.

In February 2015, we sold one vacant senior living community located in Pennsylvania with 120 assisted living units for approximately $250,000, excluding closing costs. In April 2015, we sold one MOB (four buildings) located in New Mexico for $1.5 million, excluding closing costs.

During the three months ended March 31, 201 5, pursuant to the terms of our existing leases with Five Star, we purchased $4.6 million of improvements to our properties leased to Five Star, and, as a result, the annual rent payable to us by Five Star increased by approximately $0.4 million. We used cash on hand to fund these purchases.

During the three months ended March 31, 201 5 and 201 4, amounts capitalized for leasing costs and building improvements at our MOBs and our capital expenditures at our managed senior living communities were as follows (dollars in thousands):

|  | Three Months Ended

During the three months ended March 31, 201 5, commitments made for expenditures in connection with leasing space in our MOBs, such as tenant improvements and leasing costs were as follows (dollars and square feet in thousands, except per square foot amounts):

|  | New |  |  |  |  |  |  |
|  | Leases |  | Renewals |  | Total |

Total leasing costs and concession commitments per square foot per year(1) |  | $ | 4.17 |  | $ | 2.97 |  | $ | 3.07 |

| (1) |  | Includes commitments made for leasing expenditures and concessions, such as tenant improvements, leasing commissions, tenant reimbursements and free rent. Excludes expenditures at properties classified in discontinued operations.

| (2) |  | Weighted based on annualized rental income pursuant to existing leases as of March 31, 2015, including straight line rent adjustments and estimated recurring expense reimbursements and excluding lease value amortization.

We funded the foregoing capital expenditures and we expect to fund the foregoing capital commitments at our MOBs using cash on hand and borrowings under our revolving credit facility.

In February 2015, we issued 31,050,000 common shares in a public offering, raising net proceeds of approximately $660.0 million, before expenses. We used the net proceeds from this offering to repay borrowings outstanding under our revolving credit facility and for general business purposes.

On January 12, 2015, we declared a quarterly distribution of $0.39 per common share, or $79.5 million, to our common shareholders of record on January 23, 2015 for the quarter ended December 31, 2014. This distribution was paid to shareholders on February 24, 2015 using cash on hand and borrowings under our revolving credit facility.

On April 13, 2015, we declared a quarterly distribution of $0.39 per common share, or $91.7 million, to our common shareholders of record on April 2 4, 2015, for the quarter ended March 31, 2015. We expect to pay this distribution on or about May 21, 2015 using cash on hand and borrowings under our revolving credit facility.

We believe we will have access to various types of financings, including equity or debt offerings, to fund our future acquisitions and to pay our debts and other obligations as they become due. Our ability to complete and the costs of our future debt transactions depend primarily upon market conditions and our credit ratings. We have no control over market conditions. Our credit ratings depend upon evaluations by credit rating agencies of our business practices and plans and, in particular, whether we appear to have the ability to maintain our earnings and service our debt funding obligations, to space our debt maturities and to balance our use of equity and debt capital so that our financial performance and leverage ratios afford us flexibility to withstand any reasonably anticipatable adverse changes. We intend to conduct our business activities in a manner which will continue to afford us reasonable access to capital for investment and financing activities. However, there can be no assurance that we will be able to complete any equity or debt offerings or that our cost of any future public or private financings will not increase.

Off Balance Sheet Arrangements

As of March 31, 201 5, we had no off balance sheet arrangements that have had or that we expect would be reasonably likely to have a future material effect on our financial condition, changes in financial condition, revenues, expenses, results of operations, liquidity, capital expenditures or capital resources.

Debt Covenants

Our principal debt obligations at March 31, 2015 were: (1) six public issuances of senior unsecured notes, including: (a) $250.0 million principal amount at an annual interest rate of 4.30% due 2016, (b) $400.0 million principal amount at an

31

Table of Contents

annual interest rate of 3.25% due 2019, (c) $200.0 million principal amount at an annual interest rate of 6.75% due 2020, (d) $300.0 million principal amount at an annual interest rate of 6.75% due 2021, (e) $250.0 million principal amount at an annual interest rate of 4.75% due 2024 and (f) $350.0 million principal amount at an annual inte rest rate of 5.625% due 2042; (2) our $350.0 million principal amount term loan; and (3) $6 09.0 million aggregate principal amount of mortgages secured by 4 6 of our properties (4 8 buildings) with maturity dates from 2015 to 2043. We also have two properties encumbered by capital leases totaling $12.6 million at March 31, 201 5. The capital leases expire in 2026. We had no amounts outstanding under our unsecured revolving credit facility as of March 31, 2015. Our credit agreement for our unsecured revolving credit facility and our unsecured term loan provides for acceleration of payment of all amounts outstanding upon the occurrence and continuation of certain events of default, such as a change of control of us, which includes RMR ceasing to act as our business manager and property manager. Our senior unsecured notes are governed by an indenture. This indenture and its supplements and our revolving credit facility and term loan agreements contain a number of covenants which restrict our ability to incur debts, including debts secured by mortgages on our properties in excess of calculated amounts, restrict our ability to make distributions under certain circumstances and generally require us to maintain certain other financial ratios. As of March 31, 2015, we believe we were in compliance with all of the covenants under our indenture and its supplements, our revolving credit facility and term loan agreements and our other debt obligations.

Neither our senior unsecured notes indenture and its supplements, nor our credit facility and term loan agreements, contain provisions for acceleration which could be triggered by our debt ratings. However, under our credit agreement and term loan agreements our senior unsecured debt ratings are used to determine the fees and interest rates we pay. Accordingly, if our debt rating s are downgraded by certain credit rating agencies, our interest expense and related costs under our credit facility and term loan agreements would increase.

O ur senior unsecured notes indenture and its supplements contain cross default provisions to any other debts of more than $20.0 million. Similarly, our revolving credit facility and term loan agreements have cross default provisions to other indebtedness that is recourse of $25.0 million or more and indebtedness that is non-recourse of $75.0 million or more.

Related Person Transactions

We have relationships and historical and continuing transactions with Five Star, RMR and others affiliated with them, including other companies to which RMR provides management services and which have trustees, directors and officers who are also trustees, directors or officers of us or RMR.

Impact of Government Reimbursement

As of March 31, 2015, approximately 97% of our NOI was generated from properties where a majority of the NOI is derived from our tenants’ and residents’ private resources, and the remaining 3% of our NOI was generated from properties where a majority of the NOI was derived from Medicare and Medicaid payments. Nonetheless, we own and our tenants and managers operate facilities in many states that participate in federal and state healthcare payment programs, including the federal Medicare and state Medicaid programs for services in SNFs and other similar facilities, state Medicaid programs for services in certain assisted living communities, and other federal and state healthcare payment programs. Because of the current and projected federal budget deficit and other federal spending priorities and challenging state fiscal conditions, there have been numerous recent legislative and regulatory actions or proposed actions with respect to federal Medicare rates and state Medicaid rates and federal payments to states for Medicaid programs. Examples of these, and other information regarding such programs, are provided below as well as under the caption “Business—Government Regulation and Reimbursement” in our Annual Report.

The Centers for Medicare and Medicaid Services, or CMS, updates prospective payment system rates each year. CMS issued updated Medicare prospective payment system rates for SNFs effective October 1, 2013, which CMS estimated would result in a net increase of approximately 1.3% in aggregate Medicare payments for SNFs, or approximately $470 million, in federal fiscal year 2014. CMS issued updated Medicare prospective payment rates for SNFs for federal fiscal year 2015, which went into effect on October 1, 2014. As part of this rule, CMS is applying a net increase of 2.0% to Medicare payment rates for SNFs, which takes into account a 2.5% market basket increase for inflation reduced by a 0.5% productivity adjustment and will result in an aggregate increase of approximately $750 million in payments to SNFs in federal fiscal year 201 5.

On April 15, 2015, CMS released its proposed rule for the Medicare prospective payment system for SNFs for federal fiscal year 2016, which would take effect on October 1, 2015. As part of this rule, CMS propose s to apply a net increase of 1.4% to Medicare payment rates for SNFs, which takes into account a 2.6% market basket increase reduced by a 0.6% forecast error and a 0.6% productivity adjustment and would result in an aggregate increase of approximately $500 million in payments to SNFs in federal fiscal year 201 6. As discussed in our Annual Report, Medicare rates have also been subject to reductions since April 2014 due to sequestration. The Medicare Access and CHIP Reauthorization Act of 2015, or MACRA, discussed below, limits the market basket increase for SNFs to 1.0% in federal fiscal year 2018.

As part of its rule for federal fiscal year 2016, CMS proposes to amend the Medicare and Medicaid conditions of participation to require SNFs to submit staffing information based on payroll and other verifiable data to CMS. CMS also proposes to establish a SNF quality reporting program, as required by the Improving Medicare Post-Acute Transformation Act of 2014, or the IMPACT Act. Starting in federal fiscal year 2018, CMS will reduce annual payment updates by 2% for SNFs that fail to submit required quality data. In addition, CMS proposes a 30-day all-cause all-condition hospital readmission measure for SNFs, to be adopted as part of a new value-based purchasing program that will provide incentive payments to SNFs for quality and efficiency beginning in federal fiscal year 2019, as required by the Protecting Access to Medicare Act of 2014, or PAMA.

Our tenants’ and our and our managers’ Medicare Part B outpatient therapy revenue rates are tied to the Medicare Physician Fee Schedule, or MPFS. On April 14, 2015, Congress passed MACRA, which extended the outpatient therapy cap exceptions process from March 31, 2015 until January 1, 2018, further postponing the implementation of strict limits on Medicare payments for outpatient therapies. MACRA also repealed the Sustainable Growth Rate, or SGR, formula for calculating updates to MPFS rates, which would have led to a 21.2% rate reduction effective April 1, 2015, and replaced the SGR formula with a different reimbursement methodology.

We are unable to predict the overall impact on us of these or other recent legislative and regulatory actions or proposed actions with respect to federal Medicare payment systems and rates.

Under the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively, the ACA, the federal government will pay for 100% of a state’s Medicaid expansion costs for the first three years (2014-2016) and gradually reduce its subsidy to 90% for 2020 and future years. As of April 29, 2015, 1 7 states have elected not to broaden Medicaid eligibility under the ACA at this time, and f our remain undecided;

33

Table of Contents

those states choosing not to participate in Medicaid expansion are forgoing the federal funds that would otherwise be available for that purpose. In addition, although Medicaid is exempt from the sequestration process noted above, some of the states in which our senior living communities operate either have not raised Medicaid rates by amounts sufficient to offset increasing costs or have frozen or reduced, or are expected to freeze or reduce, Medicaid rates. We are unable to predict the impact on us of these or other recent legislative and regulatory actions or proposed actions with respect to state Medicaid rates and payments to states for Medicaid programs.

The ACA also includes various provisions affecting Medicare and Medicaid providers, including expanded public disclosure requirements for SNFs and other providers, enforcement reforms, and increased funding for Medicare and Medicaid program integrity control initiatives. We are unable to predict the impact on us, our tenants and our managers of the insurance reforms, payment reforms, and healthcare delivery systems reforms contained in and to be developed pursuant to the ACA. Expanded insurance availability may provide more paying customers to us, our tenants and managers. If the changes implemented under the ACA result in reduced payments for services that our tenants or our managers provide or the failure of Medicare, Medicaid or insurance payment rates to cover our or our tenants’ costs, including the rents and management fees paid to us, our future financial results could be adversely and materially affected.

In addition, on November 7, 2014, the U.S. Supreme Court agreed to hear a lawsuit challenging the legality of an Internal Revenue Service regulation that allows eligible individuals in all states to receive subsidies for health insurance under the ACA, even in states that have not established their own health exchanges. Such subsidies have provided certain eligible taxpayers with the ability to purchase or maintain health insurance. We are unable to predict the outcome of that challenge or its impact on our business.

We cannot estimate the type and magnitude of the potential regulatory changes discussed above, but they may be material to and adversely affect the ability of our tenants to pay us rent, the profitability of our managed senior living communities and the values of our properties. The changes implemented or to be implemented could result in the failure of Medicare, Medicaid or private payment rates to cover our or our tenants’ costs of providing required services to residents, in reductions in payments or other circumstances that could have a material adverse effect on the ability of our tenants to pay rent to us, the profitability of our managed senior living communities and the values of our properties.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to risks associated with market changes in interest rates. We manage our exposure to this market risk by monitoring available financing alternatives. Our strategy to manage exposure to changes in interest rates has not materially changed since December 31, 201 4. Other than as described below, we do not currently foresee any significant changes in our exposure to fluctuations in interest rates or in how we manage this exposure in the near future.

| (1) |  | We assumed secured fixed rate debt of $1 39.2 million with a weighted average interest rate of 4.59% encumbering 1 6 properties in connection with our acquisition of 3 7 senior living communities in May 2015. As these debt assumptions occurred after March 31, 2015, they are not reflected in the above table.

| (2) |  | The principal balances and interest rates are the amounts stated in the applicable contracts. In accordance with GAAP, our carrying values and recorded interest expense may differ from these amounts because of market conditions at the time we assumed these debts. This table does not include obligations under capital leases.

| (3) |  | We repaid this debt in April 2015.

No principal repayments are due under our unsecured notes or bonds until maturity. Our mortgage debt require s principal and interest payments through maturity pursuant to amortization schedules. Because these debts bear interest at a fixed rate, changes in market interest rates during the term of these debts will not affect our interest obligations. If these debts were refinanced at interest rates which are 100 basis points higher or lower than shown above, our annual interest cost would increase or decrease by approximately $2 3.6 million.

Changes in market interest rates would affect the fair value of our fixed rate debt obligations; increases in market interest rates decrease the fair value of our fixed rate debt, while decreases in market interest rates increase the fair value of our fixed rate debt. Based on the balances outstanding at March 31, 201 5, and discounted cash flow

analyses through the respective maturity dates and assuming no other changes in factors that may affect the fair value of our fixed rate debt obligations, a hypothetical immediate 100 basis point change in interest rates would change the fair value of those obligations by approximately $2 0.6 million.

Our senior unsecured notes and some of our mortgages contain provisions that allow us to make repayments earlier than the stated maturity date. In some cases, we are not allowed to make early repayment prior to a cutoff date and we are generally allowed to make prepayments only at a premium equal to a make whole amount, as defined, which is generally designed to preserve a stated yield to the noteholder. In the past, we have repurchased and retired some of our outstanding debts and we may do so again in the future. These prepayment rights and our ability to repurchase and retire outstanding debt may afford us opportunities to mitigate the risk of refinancing our debts at maturity at higher rates by refinancing prior to maturity.

At March 31, 201 5, our current floating rate debt obligations consisted of our $750.0 million unsecured revolving credit facility, under which we had no outstanding borrowings, and our $350.0 million unsecured term loan. Our revolving credit facility matures in January 2018, and, subject to our meeting certain conditions, including our payment of an extension fee, we have the option to extend the stated maturity date by one year to January 2019. No principal repayments are required under our revolving credit facility prior to maturity, and repayments may be made, and redrawn subject to conditions, at any time without penalty. Our term loan matures on January 15, 2020, and is prepayable without penalty at any time. In addition, our term loan includes a feature under which maximum borrowings may be increased to up to $700.0 million in certain circumstances.

Borrowings under our revolving credit facility and term loan are in U.S. dollars and bear interest at LIBOR plus premiums that are subject to adjustment based upon changes to our credit ratings. Accordingly, we are vulnerable to changes in U.S. dollar based short term rates, specifically LIBOR. In addition, upon renewal or refinancing of our revolving credit facility or our term loan, we are vulnerable to increases in interest rate premiums due to market conditions or our perceived credit characteristics. Generally, a change in interest rates would not affect the value of our floating rate debt but would affect our operating results.

The following table presents the impact a 100 basis point increase in interest rates would have on our annual floating rate interest expense as of March 31, 201 5 (dollars in thousands):

|  | Impact of Changes in Interest Rates |  | Annual |
|  |  |  | Outstanding |  | Total Interest |  | Earnings per |
|  | Interest Rate |  | Debt |  | Expense Per Year |  | Share Impact (1) |
At March 31, 2015 |  | 1.57 | % | $ | 350,000 |  | $ | 5,495 |  | $ | 0.02 |
100 basis point increase |  | 2.57 | % | $ | 350,000 |  | $ | 8,995 |  | $ | 0.04 |

| (1) |  | Based on weighted average number of shares outstanding (basic and diluted) for the three months ended March 3 1, 201 5.

The following table presents the impact a 100 basis point increase in interest rates would have on our annual floating rate interest expense as of March 31, 201 5 if we were fully drawn on our revolving credit facility and our term loan remained outstanding (dollars in thousands):

|  | Impact of Changes in Interest Rates |
|  |  |  | Outstanding |  | Total Interest |  | Annual Earnings |
|  | Interest Rate(1) |  | Debt |  | Expense Per Year |  | per Share Impact(2) |
At March 31, 2015 |  | 1.50 | % | $ | 1,100,000 |  | $ | 16,500 |  | $ | 0.07 |
100 basis point increase |  | 2.50 | % | $ | 1,100,000 |  | $ | 27,500 |  | $ | 0.12 |

| (1) |  | Weighted based on the respective interest rates and outstanding borrowings under our credit agreement (assuming fully drawn) and term loan as of March 31, 201 5.

| (2) |  | Based on weighted average number of shares outstanding (basic and diluted) for the three months ended March 31, 2015.

Table of Contents

The foregoing tables show the impact of an immediate increase in floating interest rates. If interest rates were to change gradually over time, the impact would be spread over time. Our exposure to fluctuations in floating interest rates will increase or decrease in the future with increases or decreases in the outstanding amount of our borrowings under our revolving credit facility or other floating rate debt.

Although we have no present plans to do so, we may in the future enter into hedge agreements from time to time to mitigate our exposure to changes in interest rates.

Item 4. Controls and Procedures.

As of the end of the period covered by this report, our management carried out an evaluation, under the supervision and with the participation of our Managing Trustees, President and Chief Operating Officer and Treasurer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures pursuant to the Securities Exchange Act of 1934, as amended, Rules 13a-15 and 15d-15. Based upon that evaluation, our Managing Trustees, President and Chief Operating Officer and Treasurer and Chief Financial Officer concluded that our disclosure controls and procedures are effective.

There have been no changes in our internal control over financial reporting during the quarter ended March 3 1, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. Other Information

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

On J anuary 8, February 6 and March 8, 201 5, we issued 1 2,574, 12,689 and 11,347 of our common shares, respectively, to RMR as payment of a portion of the management fee due to RMR pursuant to our business management agreement with RMR. We issued these shares pursuant to an exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as amended.

Item 5. Other Information.

As previously disclosed, on December 22, 2014, we entered into a Purchase and Sale Agreement and Joint Escrow Instructions, or the Purchase Agreement, with CNL Lifestyle Properties, Inc. and certain of its subsidiaries, to acquire 38 senior living communities located in 16 states for an aggregate purchase price of approximately $790.0 million, including assumed debt but excluding closing costs. These communities include an aggregate of 3,466 living units, comprised of 826 independent living units, 1,860 assisted living units, 744 memory care units and 36 skilled nursing facility units. On May 1, 2015, we completed the acquisition of 37 of these senior living communities with 3,379 living u nits for $762.6 million, and we amended the Purchase Agreement to accommodate a delayed closing of the remaining one senior living community with 87 living units. The acquisition of the remaining senior living community is expected to close before year end 2015, but this acquisition is subject to various conditions; accordingly, we can provide no assurance that we will acquire this community, that the acquisition will not be delayed further or that the terms will not change. The foregoing description of the Purchase Agreement, as amended, is not complete and is qualified in its entirety by reference to the full text of the Purchase Agreement, which was previously filed as Exhibit 2.1 to our Current Report on Form 8-K dated December 22, 2014, and to the First Amendment to the Purchase Agreement, which is filed as Exhibit 2.1 to this Quarterly Report on Form 10-Q, each of which is incorporated by reference herein.

We financed this acquisition with cash on hand, by assuming approximately $1 39.2 million of mortgage debt with a wei ghted average interest rate of 4.59% and by applying approximately $550.0 million drawn under our $750.0 million unsecured revolving credit facility on April 30, 2015. Our revolving credit facility matures on January 15, 2018, subject to an option to extend the stated maturity date by one year, and the interest rate payable on borrowings under our revolving credit facility is LIBOR plus a premium of 130 basis points, which was 1.48% as of the date of the drawing. See Note 5 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for further information regarding the terms of our revolving credit facility.

Nineteen of these 38 communities, including the one community that we have not yet acquired, are leased to seven senior living operators. The 19 remaining communities were acquired using TRS structures. Five of these 19 communities will continue to be managed by the current third party senior living operator. Pursuant to pre-existing management agr eements, we paid fees of $975,5 00 and terminated the agreements for the remaining 14 of these 19 communities and we entered into management agreements with Five Star to manage these 14 communities. A representative form of these management agreements is filed as Exhibit 99.1 to this Quarterly Report on Form 10-Q and is incorporated by reference herein. For further information regarding our relationship and historical and continuing transactions with Five Star, please see Note 10 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q, which information is incorporated herein by reference, as well as our Annual Report, our definitive Proxy Statement for our 2015 Annual Meeting of Shareholders and our other filings with the SEC.

Any required financial statements or pro forma information in connection with the acquisition reported in this Item 5 will be filed with the SEC within the time period prescribed by Item 9.01(a)(4) of Form 8-K.
