PART I

Item 1.  Business.

The Company.

We are a real estate investment trust, or REIT, that was organized under the laws of the State of Maryland in 1998. As of December 31, 2015, we owned 427 properties (451 buildings) located in 43 states and Washington, D.C. (including one property  (one building) and one vacant land parcel classified as held for sale). On that date, the undepreciated carrying value of our properties, net of impairment losses, was $7.5 billion, excluding properties classified as held for sale. Our portfolio includes: 296 senior living communities, including independent living, assisted living, memory care and skilled nursing facilities, or SNFs, with 34,699 living units / beds, with an undepreciated carrying value of $4.3 billion; 121 properties (145 buildings) leased to medical providers, medical related businesses, clinics and biotech laboratory tenants, or MOBs,with 11.3million square feet of space and an undepreciated carrying value of $3.0 billion; and 10 wellness centers with approximately 812,000 square feet of interior space plus outdoor developed facilities with an undepreciated carrying value of $180.0 million.

Our principal executive offices are located at Two Newton Place, 255 Washington Street, Suite 300, Newton, Massachusetts 02458‑1634, and our telephone number is (617) 796‑8350.

We believe that the aging of the U.S. population will increase demand for existing independent and assisted senior living communities, SNFs, MOBs, wellness centers and other medical and healthcare related properties. We plan to profit from this demand by acquiring additional properties and entering into leases and management agreements with qualified tenants and managers which generate returns to us that exceed our operating and capital costs, including structuring leases that provide for or permit periodic rental increases.

Our business plan contemplates investments in senior living communities, MOBs and wellness centers. Some properties combine more than one type of service in a single building or campus. Our Board of Trustees establishes our investment, financing and disposition policies and may change them at any time without shareholder approval.

Our growth strategies are implemented and defined by our acquisition and investment, disposition and financing policies.

Senior Living Communities.

Independent Living Communities.  Independent living communities, or congregate care communities, provide high levels of privacy to residents and require residents to be capable of relatively high degrees of independence. Unlike an age restricted apartment property, an independent living community usually bundles several services as part of a regular monthly charge. For example, an independent living community may include one or two meals per day in a central dining room, daily or weekly maid service or a social director in the base charge. Additional services are generally available from staff employees on a fee for service basis. In some of our independent living communities, separate parts of the property are dedicated to assisted living and/or nursing services.

Assisted Living Communities.  Assisted living communities typically have one bedroom units which include private bathrooms and efficiency kitchens. Services bundled within one charge usually include three meals per day in a central dining room, daily housekeeping, laundry, medical reminders and 24 hour availability of assistance with the activities of daily living, such as dressing and bathing. Professional nursing and healthcare services are usually available at the property on call or at regularly scheduled times. In some of our assisted living communities, separate parts of the property are dedicated to independent living and/or nursing services.

Skilled Nursing Facilities.  SNFs generally provide extensive nursing and healthcare services similar to those available in hospitals, without the high costs associated with operating theaters, emergency rooms or intensive care units. A typical purpose built SNF includes mostly rooms with one or two beds, a separate bathroom and shared dining facilities. Licensed nursing professionals staff SNFs 24 hours per day.

1

MOBs.

MOBs are office or commercial buildings constructed for use or operated as medical office space for physicians and other healthcare personnel, and other businesses in medical related fields, including clinics and laboratory uses. Some of our MOBs are occupied as back office facilities for healthcare companies, such as hospitals and healthcare insurance companies.

Wellness Centers.

Wellness centers typically have gymnasiums, strength and cardiovascular equipment areas, tennis and racquet sports facilities, pools, spas and children’s centers. Professional sport training and therapist services are often available. Wellness centers often market themselves as clubs for which members may pay monthly fees plus additional fees for specific services.

Other Types of Real Estate.

In the past, we have considered investing in real estate different from our existing property types, including age restricted apartment buildings and some properties located outside the United States. We may explore these or other alternative investments in the future.

Lease Terms.

The leases for our senior living communities and wellness centers are so called “triple net” leases which generally require the tenants to pay rent and all property operating expenses, to indemnify us from liability which may arise by reason of our ownership of the properties, to maintain the properties at their expense, to remove and dispose of hazardous substances on the properties in compliance with applicable law and to maintain insurance on the properties for their and our benefit. In the event of partial damage, condemnation or taking, the tenants are required to rebuild with insurance or other proceeds, if any; in the case of total destruction, condemnation or taking, we receive the insurance or other proceeds and the tenants are required to pay to us any shortfall in the amount of those proceeds versus our historical investment in the affected property; in the event of material destruction or condemnation, some of these tenants have a right to purchase the affected property for amounts at least equal to our historical investment in the affected property.

Our leases of MOBs include both triple net leases, as described above, and so called “net” and “modified gross” leases where we are responsible for operating and maintaining the properties and we charge the tenants for some or all of the property operating expenses. A small percentage of our MOB leases are so called “full service” leases where we receive fixed rent from the tenants and do not charge the tenants for any property operating expenses.

Events of Default.  Under our leases, events of default generally include:

· failure of the tenant to pay rent or any other money when due;

· failure of the tenant to provide periodic financial reports when due;

· failure of the tenant to maintain required insurance coverages;

· revocation of any material license necessary for the operation of our properties; or

· failure of the tenant to perform other terms, covenants or conditions of the lease and the continuance thereof for a specified period after written notice.

Default Remedies.  Upon the occurrence of any event of default under our leases, we generally may (subject to applicable law):

· terminate the affected lease and accelerate the rent;

· terminate the tenant’s rights to occupy and use the affected property, rent the property to another tenant and recover from the defaulting tenant the difference between the amount of rent which would have been due under the lease and the rent received pursuant to the reletting;

2

· make any payment or perform any act required to be paid or performed by the tenant under its lease;

· exercise our rights with respect to any collateral securing the lease; and

· require the defaulting tenant to reimburse us for all payments made and all costs and expenses incurred in connection with any exercise of the foregoing remedies.

For more information about our leases with Five Star Quality Care, Inc. or its subsidiaries, or Five Star, see Note 5 to our Consolidated Financial Statements included in Part IV, Item 15 of this Annual Report on Form 10-K.

Senior Living Community Management Contracts.

Because we are a REIT for U.S. federal income tax purposes, we generally may not operate our senior living communities. For certain of our senior living communities, we use the taxable REIT subsidiary, or TRS, structure authorized by the REIT Investment Diversification and Empowerment Act. Under this structure, we lease certain of our communities to our TRSs and our TRSs enter into long term management agreements with third parties for the operation of such communities. The management agreements for these communities provide the manager with a management fee, which is a percentage of the gross revenues realized at the communities, plus reimbursement for the manager’s direct costs and expenses related to the communities, and generally provide the manager with an incentive fee equal to a percentage of the annual net operating income of the communities after we realize an annual return equal to a percentage of our invested capital. The currently effective management agreements for our senior living communities generally expire between December 14, 2022 and December 31, 2035, and are generally subject to automatic renewal for two consecutive 15 year terms, unless earlier terminated or timely notice of nonrenewal is delivered. In general, we have the right to terminate these currently effective management agreements upon certain manager events of default, including, without limitation, a change in control of the manager, as defined in the management agreements, and our manager has the right to terminate the management agreements upon certain events of default applicable to us.

Although we have various rights as owner under the management agreements, we rely on the manager’s personnel, good faith, expertise, historical performance, technical resources, operating efficiencies, information systems, proprietary information and judgment to manage our managed senior living communities efficiently and effectively. We also rely on the manager to set resident fees and otherwise operate our managed senior living communities in compliance with our management agreements. For more information about our management agreements with Five Star and the related pooling agreements, see Note 5 to our Consolidated Financial Statements included in Part IV, Item 15 of this Annual Report on Form 10-K.

Acquisition and Investment Policies.

Acquisitions.Our present acquisition strategy is to acquire additional properties primarily for income and secondarily for appreciation potential. In implementing this acquisition strategy, we consider a range of factors relating to each proposed acquisition, including, but not limited to:

· use and size of the property;

· proposed acquisition price;

· existing or proposed lease or management terms;

· availability and reputation of a financially qualified lessee(s), manager(s) or guarantor(s);

· historical and projected cash flows from the operations of the property;

· estimated replacement cost of the property;

· design, physical condition and age of the property;

3

· competitive market environment of the property;

· price segment and payment sources in which the property is operated;

· strategic fit of a property within our portfolio;

· our weighted average long term cost of capital compared to projected returns we may realize by owning the property;

· level of permitted services and regulatory history of the property and its historical operators; and

· the existence of alternative sources, uses or needs for capital.

We have no policies which specifically limit the percentage of our assets which may be invested in any individual property, in any one type of property, in properties leased to any one tenant or to an affiliated group of tenants or in properties managed by any one manager or by an affiliated group of managers.

Form of Investments.  We prefer wholly owned investments in fee interests. However, circumstances may arise in which we may invest in leaseholds, joint ventures, mortgages and other real estate interests. We may invest or enter into real estate joint ventures if we conclude that by doing so we may benefit from the participation of co‑venturers or that our opportunity to participate in the investment is contingent on the use of a joint venture structure. We may invest in participating, convertible or other types of mortgages if we conclude that by doing so, we may benefit from the cash flow or appreciation in the value of a property which is not available for purchase.

Mergers and Strategic Combinations.

In the past, we have considered the possibility of entering into mergers or strategic combinations with other companies and we may explore such possibilities in the future.

Disposition Policies.

From time to time, we consider the sale of one or more of our properties or other investments. We make disposition decisions based on a number of factors, including, but not limited to, the following:

· our ability to lease the affected property on terms acceptable to us or have the affected property managed with our realizing acceptable returns;

· the tenant’s or manager’s desire to acquire the affected property;

· the tenant’s or manager’s desire to cease operating the affected property;

· the proposed sale price;

· the remaining length of the lease relating to the property and its other terms;

· the strategic fit of the property or investment within our portfolio;

· the estimated value we may receive by selling the property;

· our intended use of the proceeds we may realize from the sale of the property; and

· the existence of alternative sources, uses or needs for capital.

4

Financing Policies.

There are no limitations in our organizational documents on the amount of indebtedness we may incur. Our revolving credit facility and term loan agreements and our senior unsecured notes indentures and their supplements contain financial covenants which, among other things, restrict our ability to incur indebtedness and require us to maintain financial ratios and a minimum net worth. However, we may seek to amend these covenants or seek replacement financings with less restrictive covenants. In the future, we may decide to seek changes in the financial covenants which currently restrict our debt leverage based upon then current economic conditions, the relative availability and costs of debt versus equity capital and our need for capital to take advantage of acquisition opportunities or otherwise.

We may also seek additional capital through equity offerings, debt financings, retention of cash flows in excess of distributions to shareholders, or a combination of these methods. To the extent we obtain additional debt financing, we may do so on an unsecured basis or a secured basis. We may seek to obtain lines of credit or to issue securities senior to our common shares, including preferred shares or debt securities, some of which may be convertible into our common shares or be accompanied by warrants to purchase our common shares. We may also finance acquisitions by assuming debt, through an exchange of properties or through the issuance of equity or other securities.

We currently have a $1.0 billion unsecured revolving credit facility that we use for working capital and general business purposes and for funding acquisitions on an interim basis until we are able to refinance them with equity or long term debt. In some instances, we may assume outstanding mortgage debts in connection with our acquisition of properties, or place new mortgages on properties we own. For more information regarding our financing sources and activities, please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Our Investment and Financing Liquidity and Resources” in Part II, Item 7 of this Annual Report on Form 10‑K.

Government Regulation and Reimbursement.

The senior living and healthcare industries are subject to extensive, frequently changing federal, state and local laws and regulations. Although most of these laws and regulations affect the manner in which our tenants and managers

5

operate our properties, some of them also impact us and the values of our properties. Some of the laws that impact or may impact us or our tenants or managers include: state and local licensure laws; laws protecting consumers against deceptive practices; laws relating to the operation of our properties and how our tenants and managers conduct their operations, such as health and safety, fire and privacy laws; federal and state laws affecting assisted living communities that participate in Medicaid and federal and state laws affecting SNFs, clinics and other healthcare facilities that participate in both Medicaid and Medicare that mandate allowable costs, pricing, reimbursement procedures and limitations, quality of services and care, food service and physical plants; resident rights laws (including abuse and neglect laws) and fraud laws; anti-kickback and physician referral laws; the Americans with Disabilities Act, or the ADA, and similar state and local laws; and safety and health standards set by the federal Occupational Safety and Health Administration. Medicaid funding is available in some, but not all, states for assisted living services. State licensure standards for assisted living communities, SNFs, clinics and other healthcare facilities typically address facility policies, staffing, quality of services and care, resident rights, fire safety and physical plant matters, and related matters. We are unable to predict the future course of federal, state and local legislation or regulation. Changes in the regulatory framework could have a material adverse effect on the ability of our tenants to pay us rent, the profitability of our managed senior living communities and the values of our properties.

State and local health and social service agencies and other regulatory authorities regulate and license many senior living communities. State health authorities regulate and license clinics and other healthcare facilities. In most states in which we own properties, we and our tenants and managers are prohibited from providing certain services without first obtaining appropriate licenses. In addition, most states require a certificate of need, or CON, before an entity may open a SNF or expand services at an existing community. According to the National Conference of State Legislatures, some states also limit the number of assisted living facilities by requiring CONs. In addition, some states (such as California and Texas) that have eliminated CON laws have retained other means of limiting development of SNFs, including moratoria, licensing laws and limitations upon participation in the state Medicaid program. Senior living communities and certain other healthcare facilities must also comply with applicable state and local building, zoning, fire and food service codes before licensing or Medicare and Medicaid certification are granted. These laws and regulatory requirements could affect our ability and that of our tenants and managers to expand into new markets or to expand communities in existing markets. In addition, the operation of our properties outside of the scope of applicable licensed authority can result in us, our tenants or managers being subject to penalties and sanctions, including closure of facilities.

In addition, governmental authorities have been subjecting healthcare facilities such as those that we own to increasing numbers of inspections, surveys, investigations, audits and other potential enforcement actions. We and our tenants and managers expend considerable resources to respond to such actions. Unannounced inspections or surveys may occur annually or biannually, or even more regularly, such as following a regulatory body’s receipt of a complaint about a facility. From time to time in the ordinary course of business, we and our tenants and managers receive deficiency reports from state regulatory bodies resulting from those inspections and surveys. We and our tenants and managers seek to resolve most inspection deficiencies through a plan of corrective action relating to the affected facility’s operations. If we or our tenants or managers fail to comply with any applicable legal requirements, or are unable to cure deficiencies, certain sanctions may be imposed and, if imposed, may adversely affect the ability of our tenants to pay their rent to us, the profitability of our managed senior living communities and the values of our properties. In addition, governmental agencies typically have the authority to take or seek further action against a licensed or certified facility, including the ability to impose civil money penalties or fines; suspend, modify, or revoke a license or Medicare or Medicaid participation; suspend or deny admissions of residents; deny payments in full or in part; institute state oversight, temporary management or receivership; and impose criminal penalties. Loss, suspension or modification of a license or certification or the imposition of other sanctions or penalties could adversely affect the values of our properties, the ability of our tenants to pay their rents and the profitability of our managed senior living communities.

The Centers for Medicare and Medicaid Services, or CMS, of the United States Department of Health and Human Services, or HHS, has increased its oversight of state survey agencies in recent years, focusing its enforcement efforts on SNFs and chains of SNF operators with findings of substandard care or repeat and continuing deficiencies and violations. CMS has also sought to provide consumers with additional information relating to SNFs. Moreover, state Attorneys General typically enforce consumer protection laws relating to senior living services, clinics and other healthcare facilities. In addition, state Medicaid fraud control agencies may investigate and prosecute assisted living communities and nursing facilities, clinics and other healthcare facilities under fraud and patient abuse and neglect laws.

Current state laws and regulations allow enforcement officials to make determinations as to whether the care provided by or on behalf of our tenants or by our managers at our facilities exceeds the level of care for which a particular facility is licensed. A finding that a facility is delivering care beyond the scope of its license can result in the immediate

6

discharge and transfer of residents, which could adversely affect the ability of the tenant to pay rent to us, the profitability of our managed senior living communities and the values of our properties. Furthermore, some states and the federal government allow certain citations of one facility to impact other facilities owned or operated by the same entity or a related entity, including facilities in other states. Revocation of a license or certification at one facility could therefore impact our or a tenant’s or manager’s ability to obtain new licenses or certifications or to maintain or renew existing licenses at other facilities, which could adversely affect the ability of that tenant to pay rent to us, the profitability of that manager, the profitability and values of our properties and trigger defaults under our tenants’ leases and managers’ management agreements and our or our tenants’ or managers’ credit arrangements, or adversely affect our or our tenants’ or managers’ ability to obtain financing in the future. In addition, an adverse finding by state officials could serve as the basis for lawsuits by private plaintiffs and lead to investigations under federal and state laws, which could result in civil and/or criminal penalties against the facility as well as a related entity.

As of December 31, 2015, approximately 97% of our current net operating income, or NOI, was generated from properties where a majority of the revenue is derived from private resources, and the remaining 3% of our NOI was generated from properties where a majority of the revenue is dependent upon Medicare and Medicaid programs. Our tenants and managers operate facilities in many states and they and we participate in federal and state healthcare payment programs, including the federal Medicare and state Medicaid benefit programs for services in SNFs and other similar facilities and state Medicaid programs for services in assisted living communities. In light of the current and projected federal budget deficit 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, each of which, or in any combination, could have a material adverse effect on the ability of our tenants to pay us rent, the profitability of our managed senior living communities and the values of our properties. Examples include:

· The Patient Protection and Affordable Care Act, as amended by the Healthcare and Education Reconciliation Act, or collectively, the ACA, which was adopted in March 2010, has resulted in changes to insurance, payment systems and healthcare delivery systems. The ACA is intended to expand access to health insurance coverage and reduce the growth of healthcare expenditures while simultaneously maintaining or improving the quality of healthcare. Some of the provisions of the ACA took effect immediately, whereas others took effect or will take effect at later dates. Beginning in federal fiscal year 2012, the ACA also reduced the Skilled Nursing Facility Prospective Payment System, or SNF PPS, annual adjustment for inflation by a productivity adjustment based on national economic productivity statistics. We are unable to predict the impact of these reductions on Medicare rates for SNFs.

· The ACA established an Independent Payment Advisory Board to submit legislative proposals to Congress and take other actions with a goal of reducing Medicare spending growth and includes various other provisions affecting Medicare and Medicaid providers, including enforcement reforms and increased funding for Medicare and Medicaid program integrity control initiatives.

· In June 2012, the U.S. Supreme Court upheld two major provisions of the ACA—the individual mandate, which requires most Americans to maintain health insurance or to pay a penalty, and, as modified by the Supreme Court, the Medicaid expansion, which requires states to expand their Medicaid programs by 2014 to cover all individuals under the age of 65 with incomes not exceeding 133% of the federal poverty level. In upholding the Medicaid expansion, the U.S. Supreme Court held that it violated the U.S. Constitution as drafted but remedied the violation by modifying the expansion to preclude the Secretary of HHS from withholding existing federal Medicaid funds from states that fail to comply with the Medicaid expansion, instead allowing the Secretary only to deny new Medicaid expansion funding. Under 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. Based on the ruling, states may choose not to participate in the Medicaid expansion program without risking the loss of existing federal Medicaid funding. As of January 12, 2016, 31 states plus the District of Columbia had elected to expand Medicaid eligibility as provided under the ACA, 16 states had elected not to broaden Medicaid eligibility, and three remained undecided; those states choosing not to participate in Medicaid expansion are forgoing the federal funds that would otherwise be available for that purpose. We are unable to predict the impact of these or other recent

7

legislative and regulatory actions or proposed actions with respect to state Medicaid rates and payments to states for Medicaid programs on us.

· In June 2015, the U.S. Supreme Court decided that income tax credits under the ACA are available to individuals who purchase health insurance on an exchange created by the federal government, in the same way such credits are available to individuals who purchase health insurance on an exchange created by a state.  Such subsidies provide certain eligible taxpayers with the ability to purchase or maintain health insurance.

· Medicare reimburses SNFs under the SNF PPS, which provides a fixed payment for each day of care provided to a Medicare beneficiary. The PPS requires SNFs to assign each resident to a care group depending on that resident’s medical characteristic and service needs. These care groups are known as Resource Utilization Groups, or RUGs. The PPS payments cover substantially all Medicare Part A services the beneficiary receives. Capital costs are part of the PPS rate and are not community specific. Many states have similar Medicaid PPSs. CMS implemented the PPS for SNFs pursuant to the Balanced Budget Act of 1997 and updates PPS payments for SNFs each year by a market basket update to account for inflation.

· Effective October 1, 2010, CMS adopted rules that implemented a new PPS case mix classification system known as RUG-IV. Following the implementation of RUG-IV, Medicare billing increased nationally, partially because of the unexpectedly large proportion of patients grouped in the highest paying RUG therapy categories. CMS did not intend for the implementation of RUG-IV to increase Medicare billing, however, and in 2011, CMS adopted a final rule designed to recalibrate Medicare PPS rates for SNFs. The rule resulted in a reduction in aggregate Medicare payments for SNFs by approximately 11.1%, or $3.87 billion, in federal fiscal year 2012. CMS updated Medicare payment rates for SNFs effective October 1, 2012, which increased aggregate Medicare payment rates for SNFs by 1.8%, or $670 million, for federal fiscal year 2013. On October 1, 2013, CMS updated Medicare payments to SNFs for federal fiscal year 2014, which CMS estimated would increase payments to SNFs by 1.3%, or approximately $470 million. On July 31, 2014, CMS released a final rule updating Medicare payments to SNFs for federal fiscal year 2015, which CMS estimated would increase payments to SNFs by an aggregate of 2.0%, or approximately $750 million, compared to federal fiscal year 2014. On July 30, 2015, CMS adopted a final rule updating Medicare payments to SNFs for federal fiscal year 2016, which CMS estimated would increase payments to SNFs by an aggregate of 1.2%, or approximately $430 million, compared to federal fiscal year 2015. Due to the previous reduction of Medicare payment rates of approximately 11.1% for federal fiscal year 2012 discussed above, however, Medicare payment rates will be lower for federal fiscal year 2016 than they were in federal fiscal year 2011. 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. It is unclear whether these adjustments in Medicare rates will compensate for the increased costs our tenants and managers may incur for services to residents whose services are paid for by Medicare.

· In addition, the Middle Class Tax Relief and Job Creation Act of 2012, which was enacted in February 2012, incrementally reduced the SNF reimbursement rate for Medicare bad debt from 100% to 65% by federal fiscal year 2015 for beneficiaries dually eligible for Medicare and Medicaid. Because nearly 90% of SNF bad debt has historically been related to dual eligible beneficiaries, this rule has a substantial negative effect on SNFs. The same law also reduced the SNF Medicare bad debt reimbursement rate for Medicare beneficiaries not eligible for Medicaid from 70% to 65% in federal fiscal year 2013 and going forward.

· The federal government is also seeking to slow the growth of Medicare and Medicaid payments to SNFs in several ways, including pursuant to the Deficit Reduction Act of 2005, or the DRA. In 2006, the government implemented limits on Medicare payments for outpatient therapies but, pursuant to the DRA, created an exception process under which beneficiaries could request an exemption from the cap and be granted the amount of services deemed medically necessary by Medicare. On April 1, 2014, the Protecting Access to Medicare Act of 2014, or PAMA, extended the Medicare outpatient therapy cap exception process through March 31, 2015. In April 2015, Congress passed MACRA, which extended the outpatient therapy cap

8

exceptions process from March 31, 2015 through December 31, 2017, further postponing the implementation of strict limits on Medicare payments for outpatient therapies.

· The increased “look-back” period for prohibited asset transfers disqualifies individuals from Medicaid SNF benefits from three to five years. The period of Medicaid ineligibility begins on the date of the prohibited transfer or the date an individual has entered the SNF and would otherwise be eligible for Medicaid coverage, whichever occurs later, rather than on the date of the prohibited transfer, effectively extending the Medicaid penalty period. This increased “look-back” period effectively places an additional burden on our tenants and managers to collect charges directly from their residents and their transferees.

· Our tenants’ and our and our managers’ Medicare Part B outpatient therapy revenue rates are tied to the Medicare Physician Fee Schedule, or MPFS.  Although the MPFS had previously been scheduled to be reduced by more than 25% in 2013, MPFS rates remained fixed at the 2012 level throughout 2013 and increased 0.5% for the period beginning January 1, 2014.  On April 1, 2014, PAMA extended the 0.5% increase to the MPFS rates through December 31, 2014 and provided no increase in the MPFS rates in the period between January 1, 2015 and March 31, 2015.  MACRA, discussed above, 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.

· PAMA established a SNF value-based purchasing program, which is intended to increase quality of care and reduce preventable hospitalizations. Under this program, HHS will assess SNFs based on hospital readmissions and make these assessments available to the public by October 1, 2017.  As part of PAMA implementation, in the SNF PPS final rule for fiscal year 2016, CMS adopted a 30 day all-cause, all-condition hospital readmission measure for SNFs, which, by October 1, 2016, will be replaced with an all-condition, risk-adjusted potentially preventable hospital readmission rate for SNFs.  Under PAMA, beginning in federal fiscal year 2019, Medicare payment rates will be partially based on SNFs’ performance scores on this measure.  To fund the program, CMS will reduce Medicare payments to all SNFs by 2.0% through a withhold mechanism starting on October 1, 2018 and then redistribute between 50% and 70% of the withheld payments as incentive payments to those SNFs with the highest rankings on this measure.

· We and some of our tenants and managers are subject to the Improving Medicare Post-Acute Care Transformation Act of 2014, or the IMPACT Act, which requires certain post-acute care providers, including SNFs, to begin collecting and reporting various types of data.  Beginning in federal fiscal year 2018, SNFs that fail to comply with the reporting requirements by the established times will be subject to a 2.0% reduction in their Medicare payment rates for that fiscal year.  The IMPACT Act also requires the Secretary of HHS and the Medicare Payment Advisory Commission to submit reports to Congress recommending a future Medicare PPS for post-acute care providers and analyzing both its effects on the reported metrics and its financial effect on post-acute care providers.

· The Budget Control Act of 2011 and the Bipartisan Budget Act of 2013 allow for automatic reductions in federal spending by means of a process called sequestration, which reduces Medicare payment rates by 2.0% through 2023. In 2014 and 2015, Congress approved two additional one year extensions of Medicare sequestration, through 2025. Medicaid is exempt from the automatic reductions, as are certain Medicare benefits. We are unable to predict the long term financial impact of the automatic payment cuts.

· The DRA and the ACA also include provisions that encourage states to provide long term care services in home and community based settings rather than in SNFs or other inpatient facilities, including increased federal Medicaid spending for some states through the use of several programs. One such program, the Community First Choice Option, or the CFC Option, grants states that choose to participate in the program a 6% increase in federal matching payments for related medical assistance expenditures. As of December 2015, five states had obtained a State Plan Amendment to participate in the CFC Option. We are unable to predict the effect of the implementation of the CFC Option and other similar programs on the ability of our

9

tenants to pay rent to us, the profitability of our managed senior living communities and the values of our properties.

· The ACA extended and expanded eligibility for a program to award competitive grants to states for demonstration projects to provide home and community based long term care services to qualified individuals relocated from SNFs, providing certain increased federal medical assistance for each qualifying beneficiary. States are also permitted to include home and community based services as optional services under their Medicaid state plans, and states opting to do so may establish more stringent needs based criteria for SNF services than for home and community based services. The ACA also expanded the services that states may provide and limited their ability to set caps on enrollment, waiting lists or geographic limitations on home and community based services. These changes under the ACA may result in reduced payments for services, or the failure of Medicare, Medicaid or insurance payment rates to cover increasing costs. 

· CMS has developed and enforces Conditions of Participation that healthcare organizations must meet in order to participate in the Medicare and Medicaid programs.  These standards are designed to improve quality of care and protect the health and safety of beneficiaries. In July 2015, CMS released a proposed rule to comprehensively update the requirements for long term care facilities that participate in Medicare and Medicaid.  These proposals, if finalized, would increase the cost of operations for long term care facilities that participate in Medicare and Medicaid, such as SNFs.

· Some of the states in which our tenants and managers operate have not raised Medicaid rates by amounts sufficient to offset increasing costs or have frozen or reduced such rates. Effective June 30, 2011, Congress ended certain temporary increases in federal payments to states for Medicaid programs that had been in effect since 2008.  Some states are expanding their use of managed care, partly to control Medicaid program costs.  Medicaid spending grew an estimated 11% in 2014 due to increased enrollment as some states chose to expand Medicaid coverage under the ACA. From 2015 through 2024, Medicaid spending is expected to grow by an average annual rate of 5.9%, mainly driven by increased spending per beneficiary due to aging of the population and more gradual growth in enrollment.  Under the ACA, the federal government will pay for 100% of a state’s Medicaid expansion costs from 2014 to 2016 and gradually reduce its subsidy to 90% for 2020 and future years.  We expect that the ending of these temporary payments, combined with the anticipated slow recovery of state revenues, may result in increases in state budget deficits, particularly in those states that are not participating in Medicaid expansion. As a result, certain states may continue to reduce Medicaid payments to healthcare service providers including some of our tenants and us, as a part of an effort to balance their budgets.

We are unable to predict the impact of these or other recent legislative and regulatory actions or proposed actions with respect to state Medicaid rates and federal Medicare rates and federal payments to states for Medicaid programs on us and those of our tenants that derive a portion of their revenues from Medicare, Medicaid and other governmental programs. The changes implemented or to be implemented as a result of such actions could result in the failure of Medicare, Medicaid or private payment reimbursement rates to cover increasing costs, in a reduction in payments or other circumstances.

Federal and state efforts to target false claims, fraud and abuse and violations of anti-kickback, physician referral and privacy laws by providers under Medicare, Medicaid and other public and private programs have increased in recent years, as have civil monetary penalties, treble damages, repayment requirements and criminal sanctions for noncompliance. The federal False Claims Act, as amended and expanded by the Fraud Enforcement and Recovery Act of 2009 and the ACA, provides significant civil monetary penalties and treble damages for false claims and authorizes individuals to bring claims on behalf of the federal government for false claims. The federal Civil Monetary Penalties Law authorizes the Secretary of HHS to impose substantial civil penalties, treble damages and program exclusions administratively for false claims or violations of the federal anti-kickback statute. In addition, the ACA increased penalties under federal sentencing guidelines between 20% and 50% for healthcare fraud offenses involving more than $1 million. Governmental authorities are devoting increasing attention and resources to the prevention, detection, and prosecution of healthcare fraud and abuse. CMS contractors are also expanding the retroactive audits of Medicare claims submitted by SNFs and other providers, and recouping alleged overpayments for services determined by auditors not to have been medically necessary or not to meet

10

Medicare coverage criteria as billed. State Medicaid programs and other third party payers are conducting similar medical necessity and compliance audits. The ACA facilitates the Department of Justice’s, or the DOJ’s, ability to investigate allegations of wrongdoing or fraud at SNFs, in part because of increased cooperation and data sharing among CMS, the Office of the Inspector General, the DOJ and the states. In addition, the ACA requires all states to terminate the Medicaid participation of any provider that has been terminated under Medicare or any Medicaid state plan. We and our tenants and managers expend significant resources to comply with these laws and regulations.

Federal and state laws designed to protect the confidentiality and security of individually identifiable information apply to us, our tenants and our managers. Under the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, and the Health Information Technology for Economic and Clinical Health Act, we, our tenants and our managers that are “covered entities” or “business associates” within the meaning of HIPAA must comply with rules adopted by HHS governing the privacy, security, use and disclosure of individually identifiable information, including financial information and protected health information, or PHI, and also with security rules for electronic PHI. There may be both civil monetary penalties and criminal sanctions for noncompliance with such federal laws. On January 17, 2013, HHS released the HIPAA Omnibus Rule, or the Omnibus Rule, which went into effect on March 26, 2013 and required compliance with most provisions by September 23, 2013. Pursuant to the Omnibus Rule, “covered entities” were required to make certain modifications to any business associate agreements that they have in place with their “business associates” within the meaning of HIPAA. In addition, the Omnibus Rule required “covered entities” to modify and redistribute their notices of privacy practices to include certain provisions relating to the use of PHI. Further, the Omnibus Rule modified the standard for providing breach notices, which was previously to perform an analysis of the harm of any disclosure to a more objective analysis relating to whether any PHI was actually acquired or viewed as a result of the breach. In addition to HIPAA, many states have enacted their own security and privacy laws relating to individually identifiable information. In some states, these laws are more stringent than HIPAA, and we, our tenants and our managers must comply with applicable federal and state standards.

We require our tenants and managers to comply with all laws that regulate the operation of our senior living communities. Although we do not believe that the costs to comply with these laws will have a material adverse effect on us, those costs may adversely affect the profitability of our managed senior living communities and the ability of our tenants to pay their rent to us. If we or any of our tenants or managers were subject to an action alleging violations of such laws or to any adverse determination concerning any of our or our tenants’ or managers’ licenses or eligibility for Medicare or Medicaid reimbursement or any substantial penalties, repayments or sanctions, these actions could materially and adversely affect the ability of our tenants to pay rent to us, the profitability of our managed senior living communities and the values of our properties. If any of our tenants or managers becomes unable to operate our properties, or if any of our tenants becomes unable to pay its rent because it has violated government regulations or payment laws, we may experience difficulty in finding a substitute tenant or manager or selling the affected property at a price that provides us with a desirable return, and the value of the affected property may decline materially.

Federal, state and local agencies regulate our MOB tenants that provide healthcare services. Many states require medical clinics, ambulatory surgery centers, clinical laboratories and other outpatient healthcare facilities to be licensed and inspected for compliance with licensure regulations concerning professional staffing, services, patient rights and physical plant requirements, among other matters. Our tenants must comply with the ADA and similar state and local laws to the extent that such facilities are “public accommodations” as defined in those statutes. The obligation to comply with the ADA and similar laws is an ongoing obligation, and our tenants expend significant resources to comply with such laws.

Healthcare providers and suppliers, including physicians and other licensed medical practitioners, that receive federal or state reimbursement under Medicare, Medicaid or other federal or state programs must comply with the requirements for their participation in those programs. Our tenants that are healthcare providers or suppliers are subject to reimbursement rates that are increasingly subject to cost control pressures and may be reduced or may not be increased sufficiently to cover their increasing costs, including our rents.

The U.S. Food and Drug Administration, or the FDA, and other federal, state and local authorities extensively regulate our biotechnology laboratory tenants that develop, manufacture, market or distribute new drugs, biologicals or medical devices for human use. The FDA and such other authorities regulate the clinical development, testing, manufacture, quality control, safety, effectiveness, labeling, storage, record keeping, advertising and promotion of those

11

products. Before a new pharmaceutical product or medical device may be marketed and distributed in the United States, the FDA must approve it as safe and effective for human use. Preclinical and clinical studies and documentation in connection with FDA approval of new pharmaceuticals or medical devices involve significant time, expense and risks of failure. Once a product is approved, the FDA maintains oversight of the product and its developer and can withdraw its approval, recall products or suspend their production, impose or seek to impose civil or criminal penalties on the developer or take other actions for the developer’s failure to comply with regulatory requirements, including anti-fraud, false claims, anti-kickback or physician referral laws. Other concerns affecting our biotechnology laboratory tenants include the potential for subsequent discovery of safety concerns and related litigation, ensuring that the product qualifies for reimbursement under Medicare, Medicaid or other federal or state programs, cost control initiatives of payment programs, the potential for litigation over the validity or infringement of intellectual property rights related to the product, the eventual expiration of relevant patents and the need to raise additional capital. The cost of compliance with these regulations and the risks described in this paragraph, among others, could adversely affect the ability of our biotechnology laboratory tenants to pay rent to us.

Competition.

Investing in senior living communities, MOBs and wellness centers is a highly competitive business. We compete against other REITs, numerous financial institutions, individuals and public and private companies who are actively engaged in this business. Also, we compete for tenants and residents and for investments based on a number of factors including rates, financings offered, underwriting criteria and reputation. Our ability to successfully compete is also impacted by economic and population trends, availability of acceptable investment opportunities, our ability to negotiate beneficial investment terms, availability and cost of capital and new and existing laws and regulations. Some of our competitors are dominant in selected geographic or property markets, including in markets we operate. Some of our competitors may have greater financial and other resources than we have. We believe the geographic diversity of our investments, the experience and abilities of our management, the quality of our assets and the financial strength of many of our tenants and managers may afford us some competitive advantages and allow us to operate our business successfully despite the competitive nature of our business.

The tenants and managers that operate our healthcare facilities compete on a local and regional basis with operators of facilities that provide comparable services. Operators compete for residents and patients based on quality of care, reputation, physical appearance of properties, services offered, family preferences, physicians, staff, price and location. We and our tenants and managers also face competition from other healthcare facilities for tenants, such as physicians and other healthcare providers that provide comparable facilities and services.

For additional information on competition and the risks associated with our business, please see “Risk Factors” of this Annual Report on Form 10‑K.

Environmental and Climate Change Matters.

Under various laws, owners as well as tenants and operators of real estate may be required to investigate and clean up or remove hazardous substances present at or migrating from properties they own, lease or operate and may be held liable for property damage or personal injuries that result from hazardous substances. These laws also expose us to the possibility that we may become liable to reimburse governments or third parties for damages and costs they incur in connection with hazardous substances. We reviewed environmental conditions surveys of the properties we own prior to their purchase. Based upon those surveys we do not believe that there are environmental conditions at any of our properties that have had or will have a material adverse effect on us. However, no assurances can be given that conditions are not present at our properties or that costs we may be required to incur in the future to remediate contamination will not have a material adverse effect on our business or financial condition and results of operations.

Insurance.

We generally have insurance coverage for many of our MOBs and for our managed senior living communities, and our leases of other properties generally provide that our tenants are responsible for the costs of insurance coverage for the properties we lease to them, such as for casualty, including fire and extended coverage, and liability. Except in the case

12

of certain of our MOBs and our managed senior living communities, we either purchase the insurance ourselves and our tenants reimburse us, or the tenants buy the insurance directly and are required to list us as an insured party. We participate with RMR LLC and other companies to which RMR LLC provides management services in a combined property insurance program through Affiliates Insurance Company, or AIC, and with respect to which AIC is a reinsurer of certain coverage amounts. For more information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Related Person Transactions” in Part II, Item 7 of this Annual Report on Form 10-K.

Segment Reporting.

As of December 31, 2015, we have four operating segments, of which three are separate reporting segments.  The first reporting segment includes triple net senior living communities that provide short term and long term residential care and other services for residents. Properties in this segment include leased independent living communities, assisted living communities and SNFs. We earn rental income revenues from the tenants that lease and operate our leased communities. The second reporting segment includes managed senior living communities that provide short term and long term residential care and other services for residents. Properties in this segment include independent living communities and assisted living communities. We earn fees and services revenues from the residents of our managed senior living communities.  The third reporting segment includes MOBs.Our fourth segment includes the remainder of our operations, including certain properties that offer fitness, wellness and spa services to members, which we do not consider to be sufficiently material as to constitute a separate reporting segment, and all of our other operations.For further information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of this Annual Report on Form 10-K and our Consolidated Financial Statements included in Part IV, Item 15 of this Annual Report on Form 10-K.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following summary of United States federal income tax considerations is based on existing law, and is limited to investors who own our shares as investment assets rather than as inventory or as property used in a trade or business.  The summary does not discuss all of the particular tax consequences that might be relevant to you if you are subject to special rules under federal income tax law, for example if you are:

· a bank, insurance company or other financial institution;

· a regulated investment company or REIT;

· a subchapter S corporation;

13

· a broker, dealer or trader in securities or foreign currency;

· a person who marks-to-market our shares;

· a person who has a functional currency other than the United States dollar;

· a person who acquires or owns our shares in connection with employment or other performance of services;

· a person subject to alternative minimum tax;

· a person who acquires or owns our shares as part of a straddle, hedging transaction, constructive sale transaction, constructive ownership transaction or conversion transaction;

· a United States expatriate;

· a “qualified shareholder” (as defined in Section 897(k)(3)(A) of the United States Internal Revenue Code of 1986, as amended, or the IRC);

· a “qualified foreign pension fund” (as defined in Section 897(l)(2) of the IRC) or any entity wholly owned by a qualified foreign pension fund; or

· except as specifically described in the following summary, a trust, estate, tax-exempt entity or foreign person.

The sections of the IRCthat govern the federal income tax qualification and treatment of a REIT and its shareholders are complex.  This presentation is a summary of applicable IRC provisions, related rules and regulations, and administrative and judicial interpretations, all of which are subject to change, possibly with retroactive effect.  Future legislative, judicial or administrative actions or decisions could also affect the accuracy of statements made in this summary.  We have not received a ruling from the United States Internal Revenue Service, or the IRS, with respect to any matter described in this summary,and we cannot assure you that the IRS or a court will agree with all of the statements made in this summary.  The IRS could, for example, take a different position from that described in this summary with respect to our acquisitions, operations, restructurings or other matters, which, if a court agreed, could result in significant tax liabilities for applicable parties.  In addition, this summary is not exhaustive of all possible tax consequences, and does not discuss any estate, gift, state, local or foreign tax consequences.  For all these reasons, we urge you and any prospective acquiror of our shares to consult with a tax advisor about the federal income tax and other tax consequences of the acquisition, ownership and disposition of our shares.  Our intentions and beliefs described in this summary are based upon our understanding of applicable laws and regulations that are in effect as of the date of this Annual Report on Form10-K.  If new laws or regulations are enacted which impact us directly or indirectly, we may change our intentions or beliefs.

Your federal income tax consequences generally will differ depending on whether or not you are a “U.S. shareholder.”  For purposes of this summary, a “U.S. shareholder” is a beneficial owner of our shares that is:

· a citizen or resident of the United States, including an alien individual who is a lawful permanent resident of the United States or meets the substantial presence residency test under the federal income tax laws;

· an entity treated as a corporation for federal income tax purposes that is created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

· an estate the income of which is subject to federal income taxation regardless of its source; or

· a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust, or, to the extent provided in Treasury regulations, a trust in existence on August 20, 1996 that has elected to be treated as a domestic trust;

14

whose status as a U.S. shareholder is not overridden by an applicable tax treaty.  Conversely, a  “non-U.S. shareholder”is a beneficial owner of our shares other than a partnership or a U.S. shareholder.

If any entity treated as a partnership for federal income tax purposes is a beneficial owner of our shares, the tax treatment of a partner in the partnership generally will depend upon the status of the partner and the activities of the partnership.  Any entity or other arrangement treated as a partnership for federal income tax purposes that is a beneficial owner of our shares and the partners in such a partnership (as determined for federal income tax purposes) are urged to consult their own tax advisors about the federal income tax consequences of the acquisition, ownership and disposition of our shares.

Taxation as a REIT

We have elected to be taxed as a REIT under Sections 856 through 860 of the IRC, commencing with our taxable year ended December 31, 1999. Our REIT election, assuming continuing compliance with the then applicable qualification tests, has continued and will continue in effect for subsequent taxable years.  Although no assurance can be given, we believe that we have been organized and have operated, and will continue to be organized and to operate, in a manner that qualified and will continue to qualify us to be taxed under the IRC as a REIT.

As a REIT, we generally are not subject to federal income tax on our net income distributed as dividends to our shareholders.  Distributions to our shareholders generally are included in their income as dividends to the extent of our available current or accumulated earnings and profits.  Our dividends are not generally entitled to the preferential tax rates on qualified dividend income, but a portion of our dividends may be treated as capital gain dividends or as qualified dividend income, all as explained below.  No portion of any of our dividends is eligible for the dividends received deduction for corporate shareholders.  Distributions in excess of current or accumulated earnings and profits generally are treated for federal income tax purposes as returns of capital to the extent of a recipient shareholder’s basis in our shares, and will reduce this basis.  Our current or accumulated earnings and profits are generally allocated first to distributions made on our preferred shares, of which there are none outstanding at this time, and thereafter to distributions made on our common shares.  For all these purposes, our distributions include cash distributions, any in kind distributions of property that we might make, and deemed or constructive distributions resulting from capital market activities, as described below. 

Our counsel, Sullivan & Worcester LLP, has provided to us an opinion that we have been organized and have qualified for taxation as a REIT under the IRC for our 1999 through 2015 taxable years, and that our current and anticipated investments and plan of operation will enable us to continue to meet the requirements for qualification and taxation as a REIT under the IRC.  Our counsel’s opinions are conditioned upon the assumption that our leases, our declaration of trust and all other legal documents to which we are or have been a party have been and will be complied with by all parties to those documents, upon the accuracy and completeness of the factual matters described in this Annual Report on Form10-K and upon representations made by us as to certain factual matters relating to our organization and operations and our expected manner of operation.  If this assumption or a representation is inaccurate or incomplete, our counsel’s opinions may be adversely affected and may not be relied upon.  The opinions of our counsel are based upon the law as it exists today, but the law may change in the future, possibly with retroactive effect.  Given the highly complex nature of the rules governing REITs, the ongoing importance of factual determinations, and the possibility of future changes in our circumstances, no assurance can be given by Sullivan & Worcester LLP or us that we will qualify as or be taxed as a REIT for any particular year.  Any opinion of Sullivan & Worcester LLP as to our qualification or taxation as a REIT will be expressed as of the date issued.  Our counsel will have no obligation to advise us or our shareholders of any subsequent change in the matters stated, represented or assumed, or of any subsequent change in the applicable law.  Also, the opinions of our counsel are not binding on either the IRS or a court, and either could take a position different from that expressed by our counsel.

Our continued qualification and taxation as a REIT will depend upon our compliance on a continuing basis with various qualification tests imposed under the IRC and summarized below.  While we believe that we have satisfied and will satisfy these tests, our counsel does not review compliance with these tests on a continuing basis.  If we fail to qualify for taxation as a REIT in any year, we will be subject to federal income taxation as if we were a corporation taxed under subchapter C of the IRC, or a C corporation, and our shareholders will be taxed like shareholders of C corporations, meaning that federal income tax generally will be applied at both the corporate and shareholder levels.  In this event, we could be subject to significant tax liabilities, and the amount of cash available for distribution to our shareholders could be reduced or

15

eliminated.

If we qualify for taxation as a REIT and meet the tests described below, we generally will not pay federal income tax on amounts we distribute to our shareholders.  However, even if we qualify for taxation as a REIT, we may be subject to federal tax in the following circumstances:

· We will be taxed at regular corporate rates on any undistributed “real estate investment trust taxable income,” determined by including our undistributed net capital gains, if any.

· If our alternative minimum taxable income exceeds our taxable income, we may be subject to the corporate alternative minimum tax on our items of tax preference. 

· If we have net income from the disposition of “foreclosure property” that is held primarily for sale to customers in the ordinary course of business or from other nonqualifying income from foreclosure property, we will be subject to tax on this income at the highest regular corporate rate, currently 35%.

· If we have net income from prohibited transactions — that is, dispositions of inventory or property held primarily for sale to customers in the ordinary course of business other than dispositions of foreclosure property and other than dispositions excepted under a statutory safe harbor — we will be subject to tax on this income at a 100% rate.

· If we fail to satisfy the 75% gross income test or the 95% gross income test discussed below, due to reasonable cause and not due to willful neglect, but nonetheless maintain our qualification for taxation as a REIT because of specified cure provisions, we will be subject to tax at a 100% rate on the greater of the amount by which we fail the 75% gross income test or the 95% gross income test, with adjustments, multiplied by a fraction intended to reflect our profitability for the taxable year.

· If we fail to satisfy the REIT asset tests described below, due to reasonable cause and not due to willful neglect, but nonetheless maintain our qualification for taxation as a REIT because of specified cure provisions, we will be subject to a tax equal to the greater of $50,000 or the highest corporate tax rate multiplied by the net income generated by the nonqualifying assets that caused us to fail the test.

· If we fail to satisfy any provision of the IRC that would result in our failure to qualify for taxation as a REIT (other than violations of the REIT gross income tests or violations of the REIT asset tests described below), due to reasonable cause and not due to willful neglect, we may retain our qualification for taxation as a REIT but will be subject to a penalty of $50,000 for each failure.

· If we fail to distribute for any calendar year at least the sum of 85% of our REIT ordinary income for that year, 95% of our REIT capital gain net income for that year and any undistributed taxable income from prior periods, we will be subject to a 4% nondeductible excise tax on the excess of the required distribution over the amounts actually distributed.

· If we recognize gain on the disposition of a REIT asset where our basis in the asset is determined by reference to the basis of the asset in the hands of a Ccorporation during a five-year period beginning on the date on which the asset ceased to be owned by the Ccorporation, then we will pay tax at the highest regular corporate tax rate, currently 35%, on the lesser of the excess of the fair market value of the asset over the Ccorporation’s basis in the asset on the date the asset ceased to be owned by the Ccorporation, or the gain we recognize in the disposition.

· If we acquire a corporation in a transaction where we succeed to its tax attributes, to preserve our qualification for taxation as a REIT we must generally distribute all of the C corporation earnings and profits inherited in that acquisition, if any, not later than the end of our taxable year in which the acquisition occurs.  However,

16

if we fail to do so, relief provisions would allow us to maintain our qualification for taxation as a REIT provided we distribute any subsequently discovered C corporation earnings and profits and pay an interest charge in respect of the period of delayed distribution.As discussed below, we have acquired C corporations in connection with our acquisition of real estate.  Our investigations of these C corporations indicated that they did not have undistributed earnings and profits that we inherited but failed to timely distribute.  However, upon review or audit, the IRS may disagree.

· As summarized below, REITs are permitted within limits to own stock and other securities of a TRS.  A domestic TRSis separately taxed on its net income as a C corporation, and is subject to limitations on the deductibility of interest expense paid to its REIT parent.  While a foreign TRSis taxed in the United States only to the extent it has income that is effectively connected with the conduct of a trade or business in the United States or that is investment income from United States sources, a foreign TRSis generally subject to foreign taxes in the jurisdictions in which its assets or operations are located.  In addition, the REIT parent is subject to a 100% tax on the amount by which various charges and reimbursements between the parent REIT and its TRSs are determined to be priced excessively in favor of the REIT rather than on arm’s length bases.

· To the extent we invest in properties in foreign jurisdictions, our income from those properties will generally be subject to tax in those jurisdictions.  If we continue to operate as we do, then we will distribute all of our “real estate investment trust taxable income”  to our shareholders such that we will generally not pay United States federal income tax.  As a result, we cannot recover the cost of foreign income taxes imposed on our foreign investments by claiming foreign tax credits against our United States federal income tax liability.  Also, as a REIT, we cannot pass through any foreign tax credits to our shareholders.

If we fail to qualify for taxation as a REIT or elect not to qualify for taxation as a REIT, then we will be subject to federal income tax in the same manner as a regular C corporation.  Further, as a regular C corporation, distributions to our shareholders will not be deductible by us, nor will distributions be required under the IRC.  Also, to the extent of our current and accumulated earnings and profits, all distributions to our shareholders will generally be taxable as ordinary dividends potentially eligible for the preferential tax rates discussed below in “Taxation of Taxable U.S. Shareholders” and, subject to limitations in the IRC, will be potentially eligible for the dividends received deduction for corporate shareholders.  Finally, we will generally be disqualified from qualification for taxation as a REIT for the four taxable years following the taxable year in which the termination is effective.  Our failure to qualify for taxation as a REIT for even one year could result in us reducing or eliminating distributions to our shareholders, or in us incurring substantial indebtedness or liquidating substantial investments in order to pay the resulting corporate-level taxes.  Relief provisions under the IRC may allow us to continue to qualify for taxation as a REIT even if we fail to comply with various requirements, all as discussed in more detail below.

REIT Qualification Requirements

General Requirements.  Section 856(a) of the IRC defines a REIT as a corporation, trust or association:

(1)that is managed by one or more trustees or directors;

(2)the beneficial ownership of which is evidenced by transferable shares or by transferable certificates of beneficial interest;

(3)that would be taxable, but for Sections 856 through 859 of the IRC, as a domestic C corporation;

(4)that is not a financial institution or an insurance company subject to special provisions of the IRC;

(5)the beneficial ownership of which is held by 100 or more persons;

(6)that is not “closely held” as defined under the personal holding company stock ownership test, as described below; and

17

(7)that meets other tests regarding the nature of its income and assets and the amount of its distributions, all as described below.

Section 856(b) of the IRC provides that conditions (1) through (4) must be met during the entire taxable year and that condition (5) must be met during at least 335 days of a taxable year of 12 months, or during a proportionate part of a taxable year of less than 12 months.  Section 856(h)(2) of the IRC provides that neither condition (5) nor (6) need to have been met during our first taxable year as a REIT.  We believe that we have met conditions (1)through (7) duringeach of the requisite periods ending on or before the close of our most recently completed taxable year, and that we will continue to meet these conditions in future taxable years.  There can, however, be no assurance in this regard.

By reason of condition (6), we will fail to qualify for taxation as a REIT for a taxable year if at any time during the last half of a year (except for our first taxable year as a REIT) more than 50% in value of our outstanding shares is owned directly or indirectly by five or fewer individuals.  To help comply with condition (6), our declaration of trust restricts transfers of our shares that would otherwise result in concentrated ownership positions.  In addition, if we comply with applicable Treasury regulations to ascertain the ownership of our outstanding shares and do not know, or by exercising reasonable diligence would not have known, that we failed condition (6), then we will be treated as having met condition (6).  However, our failure to comply with these regulations for ascertaining ownership may result in a penalty of $25,000, or $50,000 for intentional violations.  Accordingly, we have complied and will continue to comply with these regulations, including requesting annually from record holders of significant percentages of our shares information regarding the ownership of our shares.  Under our declaration of trust, our shareholders are required to respond to these requests for information.  A shareholder who fails or refuses to comply with the request is required by Treasury regulations to submit a statement with its federal income tax return disclosing its actual ownership of our shares and other information.

For purposes of condition (6), the term “individuals” is defined in the IRC to include natural persons, supplemental unemployment compensation benefit plans, private foundations and portions of a trust permanently set aside or used exclusively for charitable purposes, but not other entities or qualified pension plans or profit-sharing trusts.  As a result, REIT shares owned by an entity that is not an “individual” are considered to be owned by the direct and indirect owners of the entity that are individuals (as so defined), rather than to be owned by the entity itself.  Similarly, REIT shares held by a qualified pension plan or profit-sharing trust are treated as held directly by the individual beneficiaries in proportion to their actuarial interests in such plan or trust.  Consequently, five or fewer such trusts could own more than 50% of the interests in an entity without jeopardizing that entity’s qualification for taxation as a REIT.  However, as discussed below in “Taxation of Tax-Exempt U.S. Shareholders,” if a REIT is a “pension-held REIT,” each qualified pension plan or profit-sharing pension trust owning more than 10% of the REIT’s shares by value generally may be taxed on a portion of the dividends it receives from the REIT.

The IRC provides that we will not automatically fail to qualify as a REIT if we do not meet conditions (1) through (6), provided we can establish that such failure was due to reasonable cause and not due to willful neglect.  Each such excused failure will result in the imposition of a $50,000 penalty instead of REIT disqualification.  It is impossible to state whether in all circumstances we would be entitled to the benefit of this relief provision.  This relief provision applies to any failure of the applicable conditions, even if the failure first occurred in a prior taxable year.

Our Wholly Owned Subsidiaries and Our Investments Through Partnerships.Except in respect of TRSs as discussed below, Section 856(i) of the IRC provides that any corporation, 100% of whose stock is held by a REIT and its disregarded subsidiaries, is a qualified REIT subsidiary and shall not be treated as a separate corporation.  The assets, liabilities and items of income, deduction and credit of a qualified REIT subsidiary are treated as the REIT’s.  We believe that each of our direct and indirect wholly owned subsidiaries, other than the TRSs discussed below (and entities owned in whole or in part by the TRSs), will be either a qualified REIT subsidiary within the meaning of Section 856(i) of the IRC, or a noncorporate entity that for federal income tax purposes is not treated as separate from its owner under Treasury regulations issued under Section 7701 of the IRC.  Thus, except for the TRSs discussed below (and entities owned in whole or in part by the TRSs), in applying all of the federal income tax REIT qualification requirements described in this summary, all assets, liabilities and items of income, deduction and credit of our direct and indirect wholly owned subsidiaries are treated as ours.

Wemay invest in real estate through one or more entities that are treated as partnerships for federal income tax purposes.  In the case of a REIT that is a partner in a partnership, Treasury regulations under the IRC provide that, for purposes

18

of the REIT qualification requirements regarding income and assets discussed below, the REIT is deemed to own its proportionate share of the assets of the partnership corresponding to the REIT’s proportionate capital interest in the partnership and is deemed to be entitled to the income of the partnership attributable to this proportionate share.  In addition, for these purposes, the character of the assets and items of gross income of the partnership generally remains the same in the hands of the REIT.  Accordingly, our proportionate share of the assets, liabilities, and items of income of each partnership in which webecome a partner is treated as ours for purposes of the income tests and asset tests discussed below.  In contrast, for purposes of the distribution requirement discussed below, we would take into account as a partner our share of the partnership’s income as determined under the general federal income tax rules governing partners and partnerships under Sections 701 through 777 of the IRC.

Subsidiary REITs.  We may in the futureinvest in real estate through one or more subsidiary entities that are intended to qualify for taxation as REITs.  Any subsidiary REIT will generally be subject to the various REIT qualification requirements and other limitations described in this summary that are applicable to us.  If one of our subsidiary REITs were to fail to qualify for taxation as a REIT, then (a) the subsidiary REIT would become subject to regular United States corporate income tax, as described above, and (b) our ownership of shares in the subsidiary REIT would cease to be a qualifying real estate asset for purposes of the 75% asset test and would become subject to the 5% asset test, the 10% vote test and the 10% value test generally applicable to our ownership in corporations other than REITs, qualified REIT subsidiaries and TRSs, all as described under “Asset Tests” below.  If a subsidiary REIT were to fail to qualify for taxation as a REIT, it is possible that we would not meet the 5% asset test, the 10% vote test or the 10% value test with respect to our interest in the subsidiary REIT, in which event we would fail to qualify for taxation as a REIT unless we could utilize applicable relief provisions.  We may make protective TRS elections as described below with respect to our subsidiary REITs and may implement other protective arrangements intended to avoid a cascading REIT failure if any of our subsidiary REITs were not to qualify for taxation as a REIT, but there can be no assurance that such protective elections and other arrangements will be effective to avoid the resulting adverse consequences to us.

Taxable REIT Subsidiaries.We are permitted to own any or all of the securities of a “taxable REIT subsidiary” as defined in Section 856(l) of the IRC, provided that no more than 25% (20% beginning with our 2018 taxable year) of the total value of our assets, at the close of each quarter, is comprised of our investments in the stock or other securities of our TRSs.  Our ownership of stock and other securities in TRSs is exempt from the 10% and 5% REIT asset tests discussed below.  Among other requirements, a TRS of ours must:

(1) be a corporation (other than a REIT) for federal income tax purposes in which we directly or indirectly own shares;

(2) join with us in making a TRS election;

(3) not directly or indirectly operate or manage a lodging facility or a health care facility; and

(4) not directly or indirectly provide to any person, under a franchise, license or otherwise, rights to any brand name under which any lodging facility or health care facility is operated, except that in limited circumstances a subfranchise, sublicense or similar right can be granted to an independent contractor to operate or manage a lodging facility or a health care facility.

In addition, any corporation (other than a REIT) in which a TRS directly or indirectly owns more than 35% of the voting power or value of the outstanding securities of such corporation will automatically be treated as a TRS.  Subject to the discussion below, we believe that we and each of our TRSs have complied with, and will continue to comply with, on a continuous basis, the requirements for TRS status at all times during which the subsidiary’s TRS election is reported as being in effect, and we believe that the same will be true for any TRS that we later form or acquire.

We acquired in the second quarter of 2015, and continue to own, an ownership position in RMR Inc. that is in excess of 10% of RMR Inc.’s outstanding securities by vote or value.  Accordingly, we elected to treat RMR Inc. as a TRS effective as of June 5, 2015.  RMR Inc., through its principal subsidiary, RMR LLC, has provided and continues to provide business and property management and other services to us and to other public and private companies, including other public REITs.  Among these clients were and are operators of lodging facilities, operators of health care facilities, and

19

owners of such facilities.  Our counsel, Sullivan & Worcester LLP, has provided to us an opinion that the activities proscribed to TRSs under Section 856(l)(3) of the IRC relating to operating or managing lodging facilities or health care facilities should include only regular onsite services or day-to-day operational activities at or for lodging facilities or health care facilities.  To the best of our knowledge, neither RMR Inc. nor RMR LLC has been or is involved in proscribed activities at or for lodging facilities or health care facilities.  Thus, we do not believe that Section 856(l)(3) of the IRC precluded or precludes RMR Inc. from being treated as our TRS.  In addition, because we acquired a significant portion of our investment in RMR Inc. in exchange for our common shares that were newly issued, our counsel, Sullivan & Worcester LLP, is of the opinion that our investment in RMR Inc. should qualify as a “temporary investment of new capital” under Section 856(c)(5)(B) of the IRC to the extent related to such issuance of our common shares.  To the extent our investment in RMR Inc. so qualifies, it will constitute a “real estate asset” under Section 856(c) of the IRC and would not constitute a security subject to the REIT asset test limitations discussed below for a one-year period commencing June 5, 2015.  If the IRS or a court determines, contrary to the opinion of our counsel, that RMR Inc. was or is precluded from being treated as our TRS, then our ownership position in RMR Inc. in excess of 10% of RMR Inc.’s outstanding securities by vote or value, except to the extent and for the period qualifying as a “temporary investment of new capital,” would be in violation of the applicable REIT asset tests described below.  Under those circumstances, however, we expect that we would qualify for the REIT asset tests’ relief provision described below, and thereby would preserve our qualification for taxation as a REIT.  If the relief provision below were to apply to us, we would be subject to tax at the highest corporate rate, currently 35%, on the net income generated by our investment in RMR Inc. in excess of a 10% ownership position in that company.

In addition, we have elected to treat as a TRS a particular corporate subsidiary of Five Star with whom we do not have a rental relationship. This intended TRS manages and operates independent living facilities for us, and in the future may operate additional independent living facilities for us. In that role, the intended TRS provides amenities and services to our tenants, the independent living residents; for the duration of our ownership of these independent living facilities, there have not been, and are not expected to be, assisted living or skilled nursing residents at these facilities, and neither we nor the intended TRS have provided or expect to provide health care services at these facilities or elsewhere.  Although the law is unclear on this point, and in fact a close read of the statute and legislative history might suggest otherwise, IRS private letter rulings conclude and imply that the management and operation of independent living facilities do not constitute operating or managing a health care facility such that TRS status is precluded, provided that there are no assisted living or skilled nursing residents in the facilities and provided further that neither the REIT nor the intended TRS provide health care services.  Although IRS private letter rulings do not generally constitute binding precedent, they do represent the reasoned, considered judgment of the IRS and thus provide insight into how the IRS applies and interprets the federal income tax laws. Based on these IRS private letter rulings, our counsel, Sullivan & Worcester LLP, has opined that it is more likely than not that our intended TRS that manages and operates pure independent living facilities will qualify as a TRS, provided that there are no assisted living or skilled nursing residents in the subject facilities and provided further that neither we nor the intended TRS provide health care services.

As discussed below, TRSs can perform services for our tenants without disqualifying the rents we receive from those tenants under the 75% gross income test or the 95% gross income test discussed below.  Moreover, because our TRSs are taxed as C corporations that are separate from us, their assets, liabilities and items of income, deduction and credit generally are not imputed to us for purposes of the REIT qualification requirements described in this summary.  Therefore, our TRSs maygenerally undertake third-party management and development activities and activities not related to real estate.  Finally, while a REIT is generally limited in its ability to earn qualifying rental income from a TRS, a REIT can earn qualifying rental income from the lease of a qualified health care property to a TRS if an eligible independent contractor operates the facility, as discussed more fully below.

Restrictions are imposed on TRSs to ensure that they will be subject to an appropriate level of federal income taxation.  For example, a TRS may not deduct interest paid in any year to an affiliated REIT to the extent that the interest payments exceed, generally, 50% of the TRS’s adjusted taxable income for that year.  However, the TRS may carry forward the disallowed interest expense to a succeeding year, and deduct the interest in that later year subject to that year’s 50% adjusted taxable income limitation.  In addition, if a TRS pays interest, rent or other amounts to its affiliated REIT in an amount that exceeds what an unrelated third party would have paid in an arm’s length transaction, then the REIT generally will be subject to an excise tax equal to 100% of the excessive portion of the payment.  Further, if in comparison to an arm’s length transaction, athird-party tenant has overpaid rent to the REIT in exchange for underpaying the TRSfor services rendered, and if the REIT has not adequately compensated the TRS for services provided to or on behalf of the third-party

20

tenant, then the REIT may be subject to an excise tax equal to 100% of the undercompensation to the TRS.  A safe harbor exception to this excise tax applies if the TRS has been compensated at a rate at least equal to 150% of its direct cost in furnishing or rendering the service.  Finally, beginning in 2016, the 100% excise tax also applies to the underpricing of services by a TRS to its parent REIT in contexts where the services are unrelated to services for REIT tenants.  There can be no assurance that arrangements involving our TRSs will not result in the imposition of one or more of these deduction limitations or excise taxes, but we do not believe that we or our TRSs are or will be subject to these impositions.

Income Tests.  There are two gross income requirements for qualification as a REIT under the IRC:

· At least 75% of our gross income for each taxable year (excluding: (a) gross income from sales or other dispositions of property held primarily for sale; (b) any income arising from “clearly identified” hedging transactions that we enter into to manage interest rate or price changes or currency fluctuations with respect to borrowings we incur to acquire or carry real estate assets; (c) any income arising from “clearly identified” hedging transactions that we enter into primarily to manage risk of currency fluctuations relating to any item that qualifies under the 75% gross income test or the 95% gross income test (or any property that generates such income or gain); (d) beginning with our 2016 taxable year, any income from “clearly identified” hedging transactions that we enter into to manage risk associated with extant hedges of liabilities or property that have been extinguished or disposed; (e) real estate foreign exchange gain (as defined in Section 856(n)(2) of the IRC); and (f) income from the repurchase or discharge of indebtedness) must be derived from investments relating to real property, including “rents from real property” as defined under Section 856 of the IRC, interest and gain from mortgages on real property or on interests in real property, income and gain from foreclosure property, gain from the sale or other disposition of real property other than dealer property, or dividends on and gain from the sale or disposition of shares in other REITs.  When we receive new capital in exchange for our shares or in a public offering of our five-year or longer debt instruments, income attributable to the temporary investment of this new capital in stock or a debt instrument, if received or accrued within one year of our receipt of the new capital, is generally also qualifying income under the 75% gross income test.

· At least 95% of our gross income for each taxable year (excluding: (a) gross income from sales or other dispositions of property held primarily for sale; (b) any income arising from “clearly identified” hedging transactions that we enter into to manage interest rate or price changes or currency fluctuations with respect to borrowings we incur to acquire or carry real estate assets; (c) any income arising from “clearly identified” hedging transactions that we enter into primarily to manage risk of currency fluctuations relating to any item that qualifies under the 75% gross income test or the 95% gross income test (or any property that generates such income or gain); (d) beginning with our 2016 taxable year, any income from “clearly identified” hedging transactions that we enter into to manage risk associated with extant hedges of liabilities or property that have been extinguished or disposed; (e) passive foreign exchange gain (as defined in Section 856(n)(3) of the IRC); and (f) income from the repurchase or discharge of indebtedness) must be derived from a combination of items of real property income that satisfy the 75% gross income test described above, dividends, interest, or gains from the sale or disposition of stock, securities or real property.

For purposes of the 75% and 95% gross income tests outlined above, income derived from a “shared appreciation provision” in a mortgage loan is generally treated as gain recognized on the sale of the property to which it relates.  Although we will use our best efforts to ensure that the income generated by our investments will be of a type that satisfies both the 75% and 95% gross income tests, there can be no assurance in this regard.

In order to qualify as “rents from real property” under Section 856 of the IRC, several requirements must be met:

· The amount of rent received generally must not be based on the income or profits of any person, but may be based on a fixed percentage or percentages of receipts or sales.

· Rents do not qualify if the REIT owns 10% or more by vote or value of the tenant (or 10% or more of the interests in the assets or net profits of the tenant, if the tenant is not a corporation), whether directly or after application of attribution rules.  While we intend not to lease property to any party if rents from that property

21

would not qualify as “rents from real property,” application of the 10% ownership rule is dependent upon complex attribution rules and circumstances that may be beyond our control.  For example, a third party’s ownership directly or by attribution of 10% or more by value of our shares, as well as an ownership position in the stock of one of our tenants which, when added to our own ownership position in that tenant, totals 10% or more by vote or value of the stock of that tenant (or 10% or more of the interests in the assets or net profits of the tenant, if the tenant is not a corporation), would result in that tenant’s rents not qualifying as “rents from real property.” Inthis regard, we already own close to, but less than, 10% of the outstanding common shares of Five Star, and Five Star has undertaken to limit its redemptions of outstanding common shares so that we do not come to own 10% or more of its outstanding common shares.  Our declaration of trust generally disallowstransfers or purported acquisitions, directly or by attribution, of our shares to the extent necessary to maintain our qualification for taxation as a REIT under the IRC.Nevertheless, there can be no assurance that these restrictions will be effective to prevent our qualification for taxation as a REIT from being jeopardized under the 10% affiliated tenant rule.  Furthermore, there can be no assurance that we will be able to monitor and enforce these restrictions, nor will our shareholders necessarily be aware of ownership of our shares attributed to them under the IRC’s attribution rules.

· There is a limited exception to the above prohibition on earning “rents from real property” from a 10% affiliated tenant where the tenant is a TRS.  If at least 90% of the leased space of a property is leased to tenants other than TRSs and 10% affiliated tenants, and if the TRS’s rent to us for space at that property is substantially comparable to the rents paid by nonaffiliated tenants for comparable space at the property, then otherwise qualifying rents paid by the TRS to the REIT will not be disqualified on account of the rule prohibiting 10% affiliated tenants.

· There is an additional exception to the above prohibition on earning “rents from real property” from a 10% affiliated tenant.  For this additional exception to apply, a real property interest in a “qualified health care property” must be leased by the REIT to its TRS, and the facility must be operated on behalf of the TRS by a person who is an “eligible independent contractor,” all as described in Sections 856(d)(8)-(9) and 856(e)(6)(D) of the IRC.  As described below, we believe our leases with our TRSs have satisfied and will continue to satisfy these requirements.

· In order for rents to qualify, we generally must not manage the property or furnish or render services to the tenants of the property, except through an independent contractor from whom we derive no income or through one of our TRSs.  There is an exception to this rule permitting a REIT to perform customary tenant services of the sort that a tax-exempt organization could perform without being considered in receipt of “unrelated business taxable income,” or UBTI, under Section 512(b)(3) of the IRC.  In addition, a de minimis amount of noncustomary services provided to tenants will not disqualify income as “rents from real property” so long as the value of the impermissible tenant services does not exceed 1% of the gross income from the property.

· If rent attributable to personal property leased in connection with a lease of real property is 15% or less of the total rent received under the lease, then the rent attributable to personal property qualifiesas “rents from real property”; if this 15% threshold is exceeded, the rent attributable to personal property doesnot so qualify.  The portion of rental income treated as attributable to personal property is determined according to the ratio of the fair market valueof the personal property to the total fair market value of the real and personal property that is rented.

· In addition, “rents from real property” includes both charges we receive for services customarily rendered in connection with the rental of comparable real property in the same geographical area, whether or not the charges are separately stated, as well as charges we receive for services provided by our TRSs when the charges are not separately stated.  Whether separately stated charges received by a REIT for services that are not geographically customary and provided by a TRS are included in “rents from real property” has not been addressed clearly by the IRS in published authorities; however, our counsel, Sullivan & Worcester LLP, is of the opinion that, although the matter is not free from doubt, “rents from real property” also includes charges we receive for services provided by our TRSs when the charges are separately stated.  Accordingly, we believe that our revenues from TRS-provided services, whether the charges are separately stated or not,

22

qualify as “rents from real property” because the services satisfy the geographically customary standard, because the services have been provided by a TRS, or for both reasons.

We believe thatall or substantially all of our rents and related service charges have qualified and will continue toqualify as “rents from real property” for purposes of Section 856 of the IRC, subject to the considerations in the following paragraph.

As discussed above, we currently own independent living facilities that we purchased to be managed and operated by a TRS; the TRS provides amenities and services, but not health care services, to the facilities’ residents, who are our tenants. We may from time to time in the future acquire additional properties to be managed and operated in this manner. Our counsel, Sullivan & Worcester LLP, has opined that it is more likely than not that our intended TRS that manages and operates independent living facilities will qualify as a TRS, provided that there are no assisted living or skilled nursing residents in the subject facilities and provided further that neither we nor the intended TRS provide health care services. Accordingly, we expect that the rents we receive from these facilities’ independent living residents will qualify as “rents from real property” because services and amenities to them are provided through a TRS.  If the IRS should assert, contrary to its current private letter ruling practice, that our intended TRS does not in fact so qualify, and if a court should agree, then the rental income we receive from the independent living facility residents who are our tenants would be nonqualifying income for purposes of the 75% and 95% gross income tests, possibly jeopardizing our compliance with the 95% gross income test.  Under those circumstances, however, we expect that we would qualify for the gross income tests’ relief provision described below, and thereby would preserve our qualification for taxation as a REIT.  If the relief provision below were to apply to us, we would be subject to tax at a 100% rate on the amount by which we failed the 95% gross income test, with adjustments, multiplied by a fraction intended to reflect our profitability for the taxable year; however, in a typical taxable year, we have little or no nonqualifying income from other sources and thus would expect to owe little tax in such circumstances.

In order to qualify as mortgage interest on real property for purposes of the 75% gross income test, interest must derive from a mortgage loan secured by real property or on interests in real property with a fair market value at the time the loan is made (reduced by any senior liens on the property) at least equal to the amount of the loan.  If the amount of the loan exceeds the fair market value of the real property (as so reduced by senior liens), the interest will be treated as interest on a mortgage loan in a ratio equal to the ratio of the fair market value of the real property (as so reduced by senior liens) to the total amount of the mortgage loan.

Absent the “foreclosure property” rules of Section 856(e) of the IRC, a REIT’s receipt of active, nonrental gross income from a property would not qualify under the 75% and 95% gross income tests.  But as foreclosure property, the active, nonrental gross income from a property would so qualify.  In the case of property leased by a REIT to a tenant, foreclosure property generally consists of the real property and incidental personal property that the REIT has reduced to possession upon a default or imminent default under the lease by the tenant, and as to which a timely foreclosure property election is made.  Any gain that a REIT recognizes on the sale of foreclosure property held as inventory or primarily for sale to customers, plus any income it receives from foreclosure property that would not qualify under the 75% gross income test in the absence of foreclosure property treatment, reduced by expenses directly connected with the production of those items of income, would be subject to income tax at the maximum corporate rate, currently 35%, under the foreclosure property income tax rules of Section 857(b)(4) of the IRC.  Thus, if a REIT should lease foreclosure property in exchange for rent that qualifies as “rents from real property” as described above, then that rental income is not subject to the foreclosure property income tax.

Other than sales of foreclosure property, any gain we realize on the sale of property held as inventory or other property held primarily for sale to customers in the ordinary course of a trade or business will be treated as income from a prohibited transaction that is subject to a penalty tax at a 100% rate.  This prohibited transaction income also may adversely affect our ability to satisfy the 75% and 95% gross income tests for federal income tax qualification as a REIT.  Whether property is held as inventory or primarily for sale to customers in the ordinary course of a trade or business is a question of fact that depends on all the facts and circumstances surrounding the particular transaction. There can be no assurance as to whether or not the IRS might successfully assert that one or more of our dispositions is subject to the 100% penalty tax.  Sections 857(b)(6)(C) and (E) of the IRC provide a safe harbor pursuant to which limited sales of real property held for at least two years and meeting specified additional requirements will not be treated as prohibited transactions.  However, compliance with the safe harbor is not always achievable in practice.

23

We believe that any gain from dispositions of assets that wehave made, or that we might make in the future, will generally qualifyas income that satisfies the 75% and 95% gross income tests and will not be subject to the 100% penalty tax, because our general intent has been and is to:

· own our assets for investment with a view to long-term income production and capital appreciation;

· engage in the business of developing, owning, leasing and managing our existing properties and acquiring, developing, owning, leasing and managing new properties; and

· make occasional dispositions of our assets consistent with our long-term investment objectives.

If we fail to satisfy one or both of the 75% gross income test or the 95% gross income test in any taxable year, we may nevertheless qualify for taxation as a REIT for that year if we satisfy the following requirements:

· our failure to meet the test is due to reasonable cause and not due to willful neglect; and

· after we identify the failure, we file a schedule describing each item of our gross income included in the 75% gross income test or the 95% gross income test for that taxable year.

It is impossible to state whether in all circumstances we would be entitled to the benefit of this relief provision for the 75% gross income test or the 95% gross income test.  Even if this relief provision does apply, a 100% tax is imposed upon the greater of the amount by which we failed the 75% gross income test or the amount by which we failed the 95% gross income test, with adjustments, multiplied by a fraction intended to reflect our profitabilityfor the taxable year.  This relief provision applies to any failure of the applicable income tests, even if the failure first occurred in a year prior to the taxable year in which the failure was discovered.

Based on the discussion above, we believe that we have satisfied, and will continue to satisfy, the 75% and 95% gross income tests outlined above on a continuing basis beginning with our first taxable year as a REIT.

Asset Tests.  At the close of each calendar quarter of each taxable year, we must also satisfy the following asset percentage tests in order to qualify for taxation as a REIT for federal income tax purposes:

· At least 75% of the value of our total assets must consist of real estate assets (which includes, beginning with our 2016 taxable year, ancillary personal property to the extent that rents attributable to such personal property are treated as rents from real property in accordance with the rules described above), cash and cash items, shares in other REITs, debt instruments issued by “publicly offered REITs” as defined in Section 562(c)(2) of the IRC (beginning with our 2016 taxable year), government securities and temporary investments of new capital (that is, any stock or debt instrument that we hold that is attributable to any amount received by us (a) in exchange for our stock or (b) in a public offering of our five-year or longer debt instruments, but only for the one year period commencing with our receipt of the new capital).

· Not more than 25% of the value of our total assets may be represented by securities other than those securities that count favorably toward the preceding 75% asset test.

· Of the investments included in the preceding 25% asset class, the value of any one non-REIT issuer’s securities that we own may not exceed 5% of the value of our total assets.  In addition, we may not own more than 10% of the vote or value of any one non-REIT issuer’s outstanding securities, unless the securities are “straight debt” securities or otherwise excepted as discussed below.  Our stock and other securities in a TRS or a qualified REIT subsidiary are exempted from these 5% and 10% asset tests.

· Not more than 25% (20% beginning with our 2018 taxable year) of the value of our total assets may be represented by stock or other securities of TRSs.

24

· Beginning with our 2016 taxable year, not more than 25% of the value of our total assets may be represented by “nonqualified publicly offered REIT debt instruments” as defined in Section 856(c)(5)(L)(ii) of the IRC.

· Our counsel, Sullivan & Worcester LLP, is of the opinion that our investments in the equity or debt of a TRS, to the extent and during the period they qualify as temporary investments of new capital, should be treated as a real estate asset, and not as a security, for purposes of the above REIT asset tests.

The above REIT asset tests must be satisfied at the close of each calendar quarter of each taxable year as a REIT.  After a REIT meets the asset tests at the close of any quarter, it will not lose its qualification for taxationas a REIT in any subsequent quarter solely because of fluctuations in the values of its assets.  This grandfathering rule may be of limited benefit to a REIT such as us that makes periodic acquisitions of both qualifying and nonqualifying REIT assets.  When a failure to satisfy the above asset tests results from an acquisition of securities or other property during a quarter, the failure can be cured by disposition of sufficient nonqualifying assets within thirtydays after the close of that quarter.

In addition, if we fail the 5% value test or the 10% vote or value tests at the close of any quarter and we do not cure such failure within thirtydays after the close of that quarter, that failure will nevertheless be excused if (a) the failure is “de minimis” and (b) within six months after the last day of the quarter in which we identify the failure, we either dispose of the assets causing the failure or otherwise satisfy the 5% value and 10% vote and value asset tests.  For purposes of this relief provision, the failure will be de minimis if the value of the assets causing the failure does not exceed the lesser of (a) 1% of the total value of our assets at the end of the relevant quarter or (b) $10,000,000.  If our failure is not de minimis, or if any of the other REIT asset tests have been violated, we may nevertheless qualify for taxation as a REIT if (a) we provide the IRS with a description of each asset causing the failure, (b) the failure was due to reasonable cause and not willful neglect, (c) we pay a tax equal to the greater of (1) $50,000 or (2) the highest rate of corporate tax imposed,  currently 35%, on the net income generated by the assets causing the failure during the period of the failure, and (d) within six months after the last day of the quarter in which we identify the failure, we either dispose of the assets causing the failure or otherwise satisfy all of the REIT asset tests.  These relief provisions apply to any failure of the applicable asset tests, even if the failure first occurred in a year prior to the taxable year in which the failure was discovered.

The IRC also provides an excepted securities safe harbor to the 10% value test that includes among other items (a) “straight debt” securities, (b) certain rental agreements in which payment is to be made in subsequent years, (c) any obligation to pay “rents from real property,” (d) securities issued by governmental entities that are not dependent in whole or in part on the profits of or payments from a nongovernmental entity, and (e) any security issued by another REIT.We have maintained and will continue to maintain records of the value of our assets to document our compliance with the above asset tests, and intend to take actions as may be required to cure any failure to satisfy the tests within thirtydays after the close of any quarter or within the six month periods described above.

Based on the discussion above, we believe that we have satisfied, and will continue to satisfy,  the above REIT asset tests on a continuing basis beginning with our first taxable year as a REIT.

Our Relationships with Five Star.  As of December 31, 2015, we owned approximately 9%of the common shares of Five Star.  Our leases with Five Star, Five Star’s charter, and other agreements collectively contain restrictions upon the ownership of Five Star common shares and require Five Star to refrain from taking any actions that may result in any affiliation with us that would jeopardize our qualification as a REIT under the IRC.  Accordingly, commencing with our 2002 taxable year, we expect that the rental income we have received and will receive from Five Star and its subsidiaries has been and will be “rents from real property” under Section 856(d) of the IRC, and therefore qualifying income under the 75% and 95% gross income tests described above.  In addition, as described above, we have elected to treat as a TRS a particular corporate subsidiary of Five Star with whom we do not have a rental relationship, and our counsel, Sullivan & Worcester LLP, has opined that it is more likely than not that this intended TRS will so qualify.  Finally, as described below, we have engaged as an intended eligible independent contractor another corporate subsidiary of Five Star with whom we do not have a rental relationship.

Our Relationship with Our TRSs.  In addition to the TRS described above that manages and operates independent living facilities for us, we also have wholly owned TRSs that lease properties from us.  We may from time to time in the future acquire additional properties to be leased in this manner.  In addition, in response to a lease default or expiration,

25

we may choose to lease a reclaimed qualified health care property to a TRS.

In lease transactions involving our TRSs, our intent is that the rents paid to us by the TRS qualify as “rents from real property” under the REIT gross income tests summarized above.  In order for this to be the case, the manager operating the leased property on behalf of the applicable TRS must be an “eligible independent contractor” within the meaning of Section 856(d)(9)(A) of the IRC, and the properties leased to the TRS must be “qualified health care properties” within the meaning of Section 856(e)(6)(D) of the IRC.  Qualified health care properties are defined as health care facilities and other properties necessary or incidental to the use of a health care facility.

For these purposes, a contractor qualifies as an “eligible independent contractor” if it is less than 35% affiliated with the REIT and, at the time the contractor enters into the agreement with the TRS to operate the qualified health care property, that contractor or any person related to that contractor is actively engaged in the trade or business of operating qualified health care properties for persons unrelated to the TRS or its affiliated REIT.  For these purposes, an otherwise eligible independent contractor is not disqualified from that status on account of (a) the TRS bearing the expenses of the operation of the qualified health care property, (b) the TRS receiving the revenues from the operation of the qualified health care property, net of expenses for that operation and fees payable to the eligible independent contractor, or (c) the REIT receiving income from the eligible independent contractor pursuant to a preexisting or otherwise grandfathered lease of another property.

We have engaged as an intended eligible independent contractor a particular corporate subsidiary of Five Star with whom we do not have a rental relationship.  This contractor and its affiliates at Five Star are actively engaged in the trade or business of operating qualified health care properties for their own accounts, including pursuant to management contracts among themselves and including properties that we do not lease to them; however, this contractor and its affiliates have few if any management contracts for qualified health care properties for third parties other than us and our TRSs. Based on a plain reading of the statute as well as applicable legislative history, our counsel, Sullivan & Worcester LLP, has opined that this intended eligible independent contractor shouldin fact so qualify.  If the IRS or a court determines that this opinion is incorrect, then the rental income we receive from our TRSs in respect of properties managed by this particular contractor would be nonqualifying income for purposes of the 75% and 95% gross income tests, possibly jeopardizing our compliance with one or both of these gross income tests.  Under those circumstances, however, we expect we would qualify for the gross income tests’ relief provision described above, and thereby would preserve our qualification for taxation as a REIT.  If the relief provision were to apply to us, we would be subject to tax at a 100% rate upon the greater of the amount by which we failed the 75% gross income test or the amount by which we failed the 95% gross income test, with adjustments, multiplied by a fraction intended to reflect our profitability for the taxable year; even though we have little or no nonqualifying income from other sources in a typical taxable year, imposition of this 100% tax in this circumstance could be material because to date substantially all of the properties leased to our TRSs are managed for the TRSs by this contractor.

As explained above, we will be subject to a 100% tax if the IRS successfully asserts that the rents paid to us by any of our TRSs exceed an arm’s length rental rate.  Although there is no clear precedent to distinguish for federal income tax purposes among leases, management contracts, partnerships, financings, and other contractual arrangements, we believe that our leases and our TRSs’ management agreements will be respected for purposes of the requirements of the IRC discussed above.  Accordingly, we expect that the rental income from our current and future TRSs will qualify as “rents from real property,” and that the 100% tax on excessive rents from a TRS will not apply.

Annual Distribution Requirements.  In order to qualify for taxation as a REIT under the IRC, we are required to make annual distributions other than capital gain dividends to our shareholders in an amount at least equal to the excess of:

(1)the sum of 90% of our “real estate investment trust taxable income” and 90% of our net income after tax, if any, from property received in foreclosure, over

(2)the amount by which our noncash income  (e.g., imputed rental income or income from transactions inadvertently failing to qualify as like-kind exchanges) exceeds 5% of our “real estate investment trust taxable income.”

26

For these purposes, our “real estate investment trust taxable income” is as defined under Section 857 of the IRC and is computed without regard to the dividends paid deduction and our net capital gain and will generally be reduced by specified corporate-level taxes that we pay (e.g., taxes on built-in gains or taxes on foreclosure property income).

For our 2014 and prior taxable years, a distribution of ours that was not pro rata within a class of our beneficial interests entitled to a distribution, or which was not consistent with the rights to distributions among our classes of beneficial interests, would have been a preferential distribution that would not have been taken into consideration for purposes of the distribution requirements, and accordingly the payment of a preferential distribution would have affected our ability to meet the distribution requirements.  Taking into account our distribution policies, including any dividend reinvestment plan we adopted, we do not believe that we made any preferential distributions in 2014 or prior taxable years.  Because we are a “publicly offered REIT” (as defined in Section 562(c)(2) of the IRC) that is required to file annual and periodic reports with the SEC under the Exchange Act,the preferential distribution rule does not apply to us beginning with our 2015 taxable year.

Distributions must be paid in the taxable year to which they relate, or in the following taxable year if declared before we timely file our federal income tax return for the earlier taxable year and if paid on or before the first regular distribution payment after that declaration.  If a dividend is declared in October, November or December to shareholders of record during one of those months, and is paid during the following January, then for federal income tax purposes the dividend will be treated as having been both paid and received on December 31 of the prior taxable year.  The 90%distribution requirements may be waived by the IRS if a REIT establishes that it failed to meet them by reason of distributions previously made to meet the requirements of the 4% excise tax discussed below.  To the extent that we do not distribute all of our net capital gain and all of our “real estate investment trust taxable income,” as adjusted, we will be subject to federal income tax at regular corporate rates on undistributed amounts.

In addition, we will be subject to a 4% nondeductible excise tax to the extent we fail within a calendar year to make required distributions to our shareholders of 85% of our ordinary income and 95% of our capital gain net income plus the excess, if any, of the “grossed up required distribution” for the preceding calendar year over the amount treated as distributed for that preceding calendar year.  For this purpose, the term “grossed up required distribution” for any calendar year is the sum of our taxable income for the calendar year without regard to the deduction for dividends paid and all amounts from earlier years that are not treated as having been distributed under the provision.  We will be treated as having sufficient earnings and profits to treat as a dividend any distribution by us up to the amount required to be distributed in order to avoid imposition of the 4% excise tax.

If we do not have enough cash or other liquid assets to meet the 90% distribution requirements, or if we so choose, we may find it necessary or desirable to arrange for new debt or equity financing to provide funds for required distributions in order to maintain our qualification for taxation as a REIT.  We can provide no assurance that financing would be available for these purposes on favorable terms, if at all.

We may be able to rectify a failure to pay sufficient dividends for any year by paying “deficiency dividends” to shareholders in a later year.  These deficiency dividends may be included in our deduction for dividends paid for the earlier year, but an interest charge would be imposed upon us for the delay in distribution.

In addition to the other distribution requirements above, to preserve our qualification for taxationas a REIT we are required to timely distribute all C corporation earnings and profits that we inherit from acquired corporations, as described below.

Acquisitions of C Corporations

We have and may in the future engage in transactions where we acquire all of the outstanding stock of a C corporation.  Upon these acquisitions, except to the extent we have made or do make an applicable TRS election, each of the acquired entities and their various corporate and noncorporate subsidiaries generally became or will become either our qualified REIT subsidiaries under Section 856(i) of the IRC or disregarded entities under Treasury regulations issued under Section 7701 of the IRC.  Thus, after the acquisition, all assets, liabilities and items of income, deduction and credit of the acquired and then disregarded entities have been and will be treated as ours for purposes of the various REIT qualification tests described above.  In addition, we generally have been and will be treated as the successor to the acquired and then

27

disregarded entities’ (a) federal income tax attributes, such as those entities’ adjusted tax bases in their assets and their depreciation schedules, and (b) earnings and profits for federal income tax purposes, if any.  The carryover of these attributes creates REIT implications such as built-in gains tax exposure and additional distribution requirements, as described below.However, where wehave made or willmake an election under Section 338(g) of the IRC with respect to corporations that we acquire, we generallyhave not andwill not be subject to such attribute carryovers.

Built-in Gains from C Corporations.  As described above, notwithstanding our qualification and taxation as a REIT, we may be subject to corporate taxation if we dispose of assets previously held by  a C corporation.  Specifically, if we acquire an asset from a corporation in a transaction in which our adjusted tax basis in the asset is determined by reference to the adjusted tax basis of that asset in the hands of a C corporation, and if we subsequently recognize gain on the disposition of that asset during a five-year period (or other specified period for taxable years prior to 2012) beginning on the date on which the asset ceased to be owned by the C corporation, then we will generally pay tax at the highest regular corporate tax rate, currently 35%, on the lesser of (a) the excess, if any, of the asset’s fair market value over its adjusted tax basis, each determined as of the time the asset ceased to be owned by the C corporation or (b) our gain recognized in the disposition.  Accordingly, any taxable disposition of an asset so acquired during such five-year period (or other specified period for taxable years prior to 2012) could be subject to this built-in gains tax.  To the extent of our gains in a taxable year that are subject to the built-in gains tax, net of any taxes paid on such gains with respect to that taxable year, our taxable dividends paid to you in the following year will be potentially eligible for treatment as qualified dividends that are taxed to our noncorporate U.S. shareholders at preferential rates.  However, we have not anddo not expect to sell any assets if that sale would result in the imposition of a material tax liability.  We cannot, however, provide assurance that we will not change our plans in this regard.

Earnings and Profits.  Following a corporate acquisition, we must generally distribute no later than the end of the applicable tax year all of the C corporation earnings and profits inherited in that transaction, if any, to preserve our qualification for taxation as a REIT.  If we failed orfail to do so, we would not qualify for taxation as a REIT for that year and a number of years thereafter, unless we are able to rely on the relief provision described below.  Although Sullivan & Worcester LLP is unable to render an opinion on factual determinations such as the amount of our undistributed earnings and profits, we have computed andwill compute, with the assistance of accountants as needed, the amount of undistributed earnings and profits that we inherit in our corporate acquisitions.  Based on these calculations, we believe that we did not inherit any undistributed earnings and profits that remained undistributed at the end of the applicable tax year.  However, there can be no assurance that, if audited, the IRS would not, upon subsequent examination, propose adjustments to our calculation of the undistributed earnings and profits that we inherit, including adjustments that might be deemed necessary by the IRS as a result of its examination of the companies we acquired. In any such examination, the IRS might consider all taxable years of the acquired entities as open for review for purposes of its proposed adjustments. If it is subsequently determined that we had undistributed earnings and profits as of the end of the applicable tax year, we may be eligible for a relief provision similar to the “deficiency dividends” procedure described above.  To utilize this relief provision, we would have to pay an interest charge for the delay in distributing the undistributed earnings and profits; in addition, we would be required to distribute to our shareholders, in addition to our other REIT distribution requirements, the amount of the undistributed earnings and profits less the interest charge paid.

Depreciation and Federal Income Tax Treatment of Leases

Our initial tax bases in our assets will generally be our acquisition cost.  We will generally depreciate our depreciable real property on a straight-line basis over fortyyears and our personal property over the applicable shorter periods.  These depreciation schedules may vary for properties that we acquire through tax-free or carryover basis acquisitions.

We are entitled to depreciation deductions from our facilities only if we are treated for federal income tax purposes as the owner of the facilities.  This means that the leases of the facilities must be classified for federal income tax purposes as true leases, rather than as sales or financing arrangements, and we believe this to be the case.

Distributions to our Shareholders

As discussed above, we expect to make distributions to our shareholders from time to time.  These distributions may include cash distributions, in kind distributions of property, and deemed or constructive distributions resulting from capital

28

market activities.  The United States federal income tax treatment of our distributions will vary based on the status of the recipient shareholder as more fully described below under “Taxation of Taxable U.S. Shareholders,” “Taxation of Tax-Exempt U.S. Shareholders,” and “Taxation of Non-U.S. Shareholders.”

A redemption of our shares for cash only will be treated as a distribution under Section 302 of the IRC, and hence taxable as a dividend to the extent of our available current or accumulated earnings and profits, unless the redemption satisfies one of the tests set forth in Section 302(b) of the IRC enabling the redemption to be treated as a sale or exchange of the shares.  The redemption for cash only will be treated as a sale or exchange if it (a) is “substantially disproportionate” with respect to the surrendering shareholder’s ownership in us, (b) results in a “complete termination” of the surrendering shareholder’s entire share interest in us, or (c) is “not essentially equivalent to a dividend” with respect to the surrendering shareholder, all within the meaning of Section 302(b) of the IRC.  In determining whether any of these tests have been met, a shareholder must generally take into account shares considered to be owned by such shareholder by reason of constructive ownership rules set forth in the IRC, as well as shares actually owned by such shareholder.  In addition, if a redemption is treated as a distribution under the preceding tests, then a shareholder’s tax basis in the redeemed shares generally will be transferred to the shareholder’s remaining shares in us, if any, and if such shareholder owns no other shares in us, such basis generally may be transferred to a related person or may be lost entirely.  Because the determination as to whether a shareholder will satisfy any of the tests of Section 302(b) of the IRC depends upon the facts and circumstances at the time that our shares are redeemed, we urge you to consult your own tax advisor to determine your particular tax treatment of any redemption.

Taxation of Taxable U.S. Shareholders

For noncorporate U.S. shareholders, to the extent that their total adjusted income does not exceed applicable thresholds, the maximum federal income tax rate for long-term capital gains and most corporate dividends is generally 15%.  For those noncorporate U.S. shareholders whose total adjusted income exceeds the applicable thresholds, the maximum federal income tax rate for long-term capital gains and most corporate dividends is generally 20%.  However, because we are not generally subject to federal income tax on the portion of our “real estate investment trust taxable income” distributed to our shareholders, dividends on our shares generally are not eligible for such preferential tax rates, except that any distribution of C corporation earnings and profits and taxed built-in gain items will potentially be eligible for these preferential tax rates.  As a result, our ordinary dividends are generallytaxed at the higher federal income tax rates applicable to ordinary income.  To summarize, the preferential federal income tax rates for long-term capital gains and for qualified dividends generally apply to:

(1)long-term capital gains, if any, recognized on the disposition of our shares;

(2)our distributions designated as long-term capital gain dividends (except to the extent attributable to real estate depreciation recapture, in which case the distributions are subject to a maximum 25% federal income tax rate);

(3)our dividends attributable to dividend income, if any, received by us from C corporations such as TRSs;

(4)our dividends attributable to earnings and profits that we inherit from C corporations; and

(5)our dividends to the extent attributable to income upon which we have paid federal corporate income tax (such as sale gains subject to the 35% built-in gains tax), net of the corporate taxes thereon.

As long as we qualify for taxation as a REIT, a distribution to our U.S. shareholders that we do not designate as a capital gain dividend generally will be treated as an ordinary income dividend to the extent of our available current or accumulated earnings and profits.  Distributions made out of our current or accumulated earnings and profits that we properly designate as capital gain dividends generally will be taxed as long-term capital gains, as discussed below, to the extent they do not exceed our actual net capital gain for the taxable year.  However, corporate shareholders may be required to treat up to 20% of any capital gain dividend as ordinary income under Section 291 of the IRC.

In addition, we may elect to retain net capital gain income and treat it as constructively distributed.  In that case:

29

(1)we will be taxed at regular corporate capital gains tax rates on retained amounts;

(2)each U.S. shareholder will be taxed on its designated proportionate share of our retained net capital gains as though that amount were distributed and designated a capital gain dividend;

(3)each U.S. shareholder will receive a credit or refund for its designated proportionate share of the tax that we pay;

(4)each U.S. shareholder will increase its adjusted basis in our shares by the excess of the amount of its proportionate share of these retained net capital gains over the U.S. shareholder’s proportionate share of the tax that we pay; and

(5)both we and our corporate shareholders will make commensurate adjustments in our respective earnings and profits for federal income tax purposes.

If we elect to retain our net capital gains in this fashion, we will notify our U.S. shareholders of the relevant tax information within sixtydays after the close of the affected taxable year.

If for any taxable year we designate capital gain dividends for our shareholders, then a portion of the capital gain dividends we designate will be allocated to the holders of a particular class of shares on a percentage basis equal to the ratio of the amount of the total dividends paid or made available for the year to the holders of that class of shares to the total dividends paid or made available for the year to holders of all outstanding classes of our shares.  We will similarly designate the portion of any capital gain dividend that is to be taxed to noncorporate U.S. shareholders at preferential maximum rates (including any capital gains attributable to real estate depreciation recapture that are subject to a maximum 25% federal income tax rate) so that the designations will be proportionate among all outstanding classes of our shares.

Distributions in excess of current or accumulated earnings and profits will not be taxable to a U.S. shareholder to the extent that they do not exceed the shareholder’s adjusted tax basis in the shareholder’s shares, but will reduce the shareholder’s basis in those shares.  To the extent that these excess distributions exceed a U.S. shareholder’s adjusted basis in our shares, they will be included in income as capital gain, with long-term gain generally taxed to noncorporate U.S. shareholders at preferential maximum rates.  No U.S. shareholder may include on its federal income tax return any of our net operating losses or any of our capital losses.

If a dividend is declared in October, November or December to shareholders of record during one of those months, and is paid during the following January, then for federal income tax purposes the dividend will be treated as having been both paid and received on December 31 of the prior taxable year.  Also, items that are treated differently for regular and alternative minimum tax purposes are to be allocated between a REIT and its shareholders under Treasury regulations which are to be prescribed.  It is possible that these Treasury regulations will permit or require tax preference items to be allocated to our shareholders with respect to any accelerated depreciation or other tax preference items that we claim.  Also, until such time as regulations are issued, we may choose to allocate applicable tax preference items to our shareholders.

A U.S. shareholder will generally recognize gain or loss equal to the difference between the amount realized and the shareholder’s adjusted basis in our shares that are sold or exchanged.  This gain or loss will be capital gain or loss, and will be long-term capital gain or loss if the shareholder’s holding period in ourshares exceeds one year.  In addition, any loss upon a sale or exchange of our shares held for six months or less will generally be treated as a long-term capital loss to the extent of any long-term capital gain dividends wepaid on such shares during the holding period.

U.S. shareholders who are individuals, estates or trusts are generally required to pay a 3.8% Medicare tax on their net investment income (including dividends on and gains from the sale or other disposition of our shares), or in the case of estates and trusts on their net investment income that is not distributed, in each case to the extent that their total adjusted income exceeds applicable thresholds.

If a U.S. shareholder recognizes a loss upon a disposition of our shares in an amount that exceeds a prescribed threshold, it is possible that the provisions of Treasury regulations involving “reportable transactions” could apply, with a

30

resulting requirement to separately disclose the loss-generating transaction to the IRS.  These Treasury regulations are written quite broadly, and apply to many routine and simple transactions.  A reportable transaction currently includes, among other things, a sale or exchange of our shares resulting in a tax loss in excess of (a) $10 million in any single year or $20 million in a prescribed combination of succeeding tax years in the case of our shares held by a C corporation or by a partnership with only C corporation partners or (b) $2 million in any single year or $4 million in a prescribed combination of succeeding tax years in the case of our shares held by any other partnership or an S corporation, trust or individual, including losses that flow through pass through entities to individuals.  A taxpayer discloses a reportable transaction by filing IRS Form 8886 with its federal income tax return and, in the first year of filing, a copy of Form 8886 must be sent to the IRS’s Office of Tax Shelter Analysis.  The annual maximum penalty for failing to disclose a reportable transaction is generally $10,000 in the case of a natural person and $50,000 in any other case.

Noncorporate U.S. shareholders who borrow funds to finance their acquisition of our shares could be limited in the amount of deductions allowed for the interest paid on the indebtedness incurred.  Under Section 163(d) of the IRC, interest paid or accrued on indebtedness incurred or continued to purchase or carry property held for investment is generally deductible only to the extent of the investor’s net investment income.  A U.S. shareholder’s net investment income will include ordinary income dividend distributions received from us and, if an appropriate election is made by the shareholder, capital gain dividend distributions and qualified dividends received from us; however, distributions treated as a nontaxable return of the shareholder’s basis will not enter into the computation of net investment income.

Taxation of Tax‑Exempt U.S. Shareholders

The rules governing the federal income taxation of tax-exempt entities are complex, and the following discussion is intended only as a summary of these rules.  If you are a tax-exempt shareholder, we urge you to consult with your own tax advisor to determine the impact of federal, state, local and foreign tax laws, including any tax return filing and other reporting requirements, with respect to your investment in our shares.

Subject to the pension-held REIT rules discussed below, our distributions made to shareholders that are tax-exempt pension plans, individual retirement accounts or other qualifying tax-exempt entities should not constitute UBTI, provided that the shareholder has not financed its acquisition of our shares with “acquisition indebtedness” within the meaning of the IRC, that the shares are not otherwise used in an unrelated trade or business of the tax-exempt entity, and that, consistent with our present intent, we do not hold a residual interest in a real estate mortgage investment conduit.

Any trusts that are described in Section 401(a) of the IRC and are tax-exempt under Section 501(a) of the IRC, or tax-exempt pension trusts, that own more than 10% by value of a “pension-held REIT” at any time during a taxable year may be required to treat a percentage of all dividends received from the pension-held REIT during the year as UBTI.  This percentage is equal to the ratio of:

(1) the pension-held REIT’s gross income derived from the conduct of unrelated trades or businesses, determined as if the pension-held REIT were a tax-exempt pension trust, less direct expenses related to that income, to

(2)the pension-held REIT’s gross income from all sources, less direct expenses related to that income,

except that this percentage shall be deemed to be zero unless it would otherwise equal or exceed 5%.

A REIT is a pension‑held REIT if:

· the REIT is “predominantly held” by tax‑exempt pension trusts; and

· the REIT would fail to satisfy the “closely held” ownership requirement, discussed above in “REIT Qualification Requirements,” if the stock or beneficial interests in the REIT held by tax-exempt pension trusts were viewed as held by the tax-exempt pension trusts rather than by their respective beneficiaries.

A REIT is predominantly held by tax-exempt pension trusts if at least one tax-exempt pension trust owns more than

31

25% by value of the interests in such REIT, or if one or more tax-exempt pension trusts, each owning more than 10% by value of the interests in such REIT, own in the aggregate more than 50% by value of the interests in such REIT.  Because of the share ownership concentration restrictions contained in our declaration of trust, we believe that we havenot beenand will not become a pension-held REIT and accordingly, the tax treatment described above should be inapplicable to our tax-exempt shareholders.  However, because our shareshave been and are expected to remain publicly traded, we cannot completely control whether or not we are or will become a pension-held REIT.

Social clubs, voluntary employee benefit associations and supplemental unemployment benefit trusts exempt from federal income taxation under Sections 501(c)(7), (c)(9) and (c)(17) of the IRC, respectively, are subject to different UBTI rules, which generally will require them to characterize distributions from a REIT as UBTI.  In addition, these prospective investors should consult their own tax advisors concerning any “set aside” or reserve requirements applicable to them.

Taxation of Non‑U.S. Shareholders

The rules governing the United States federal income taxation of non-U.S. shareholders are complex, and the following discussion is intended only as a summary of these rules.  If you are a non-U.S. shareholder, we urge you to consult with your own tax advisor to determine the impact of United States federal, state, local and foreign tax laws, including any tax return filing and other reporting requirements, with respect to your investment in our shares.

In general, a non-U.S. shareholder will be subject to regular United States federal income tax in the same manner as a U.S. shareholder with respect to its investment in our shares if that investment is effectively connected with the non-U.S. shareholder’s conduct of a trade or business in the United States (and, if provided by an applicable income tax treaty, is attributable to a permanent establishment or fixed base the non-U.S. shareholder maintains in the United States).  In addition, a corporate non-U.S. shareholder that receives income that is or is deemed effectively connected with a trade or business in the United States may also be subject to the 30% branch profits tax under Section 884 of the IRC, or lower applicable tax treaty rate, which is payable in addition to regular United States federal corporate income tax.  The balance of this discussion of the United States federal income taxation of non-U.S. shareholders addresses only those non-U.S. shareholders whose investment in our shares is not effectively connected with the conduct of a trade or business in the United States.

A distribution by us to a non-U.S. shareholder that is not attributable to gain from the sale or exchange of a “United States real property interest” within the meaning of Section 897 of the IRC, or a USRPI, and that is not designated as a capital gain dividend will be treated as an ordinary income dividend to the extent that it is made out of current or accumulated earnings and profits.  A distribution of this type will generally be subject to United States federal income tax and withholding at the rate of 30%, or at a lower rate if the non-U.S. shareholder has in the manner prescribed by the IRS demonstrated to the applicable withholding agent its entitlement to benefits under a tax treaty. In the case of any deemed or constructive distributions or a distribution in kind, the applicable withholding agent will have to collect the amount required to be withheld by reducing to cash for remittance to the IRS a sufficient portion of the property that the non-U.S. shareholder would otherwise receive or own, and the non-U.S. shareholder may bear brokerage or other costs for this withholding procedure.  Because we cannot determine our current and accumulated earnings and profits until the end of the taxable year, withholding at the rate of 30% or applicable lower treaty rate will generally be imposed on the gross amount of any distribution to a non-U.S. shareholder that we make and do not designate as a capital gain dividend.  Notwithstanding this potential withholding on distributions in excess of our current and accumulated earnings and profits, these distributions are a nontaxable return of capital to the extent that they do not exceed the non-U.S. shareholder’s adjusted basis in our shares, and the nontaxable return of capital will reduce the adjusted basis in these shares.  To the extent that distributions in excess of current and accumulated earnings and profits exceed the non-U.S. shareholder’s adjusted basis in our shares, the distributions will give rise to tax liability if the non-U.S. shareholder would otherwise be subject to tax on any gain from the sale or exchange of these shares, as discussed below.  A non-U.S. shareholder may seek a refund from the IRS of amounts withheld on distributions to it in excess of our current and accumulated earnings and profits.

From time to time, some of our distributions may be attributable to the sale or exchange of USRPIs.  However, capital gain dividends that are received by a non-U.S. shareholder, as well as dividends attributable to our sales of USRPIs, will be subject to the taxation and withholding regime applicable to ordinary income dividends and the branch profits tax will not apply, provided that (a) these dividends are received with respect to a class of shares that is “regularly traded” on a domestic “established securities market” such as the New York Stock Exchange, or theNYSE, both terms as defined by

32

applicable Treasury regulations, and (b) the non-U.S. shareholder does not own more than 10% (5% for dividends before December 18, 2015) of that class of shares at any time during the one-year period ending on the date of distribution of the applicable capital gain and USRPI dividends.  If both of these provisions are satisfied, qualifying non-U.S. shareholders will not be subject to withholding either on capital gain dividends or on dividends that are attributable to our sales of USRPIs as though those amounts were effectively connected with a United States trade or business, and qualifying non-U.S. shareholders will not be required to file United States federal income tax returns or pay branch profits tax in respect of these dividends.  Instead, these dividends will be subject to United States federal income tax and withholding as ordinary dividends, currently at a 30% tax rate unless, as discussed below, reduced by an applicable treaty.  Although there can be no assurance in this regard, we believe that our common shares have been and will remain “regularly traded” on a domestic “established securities market” within the meaning of applicable Treasury regulations; however, we can provide no assurance that our shares will continue to be “regularly traded” on a domestic “established securities market” in future taxable years.

Except as discussed above, for any year in which we qualify for taxation as a REIT, distributions that are attributable to gain from the sale or exchange of a USRPI are taxed to a non-U.S. shareholder as if these distributions were gains effectively connected with a trade or business in the United States conducted by the non-U.S. shareholder.  Accordingly, a non-U.S. shareholder that does not qualify for the special rule above (a) will be taxed on these amounts at the normal capital gain and other tax rates applicable to a U.S. shareholder, subject to any applicable alternative minimum tax and to a special alternative minimum tax in the case of nonresident alien individuals, (b) will be required to file a United States federal income tax return reporting these amounts, even if applicable withholding is imposed as described below, and (c) if such non-U.S. shareholder is also a corporation, it may owe the 30% branch profits tax under Section 884 of the IRC, or lower applicable tax treaty rate, in respect of these amounts.  The applicable withholding agent will be required to withhold from distributions to such non-U.S. shareholders, and remit to the IRS, 35% of the maximum amount of any distribution that could be designated as a capital gain dividend.  In addition, for purposes of this withholding rule, if we designate prior distributions as capital gain dividends, then subsequent distributions up to the amount of the designated prior distributions will be treated as capital gain dividends.  The amount of any tax withheld is creditable against the non-U.S. shareholder’s United States federal income tax liability, and the non-U.S. shareholder may file for a refund from the IRS of any amount of withheld tax in excess of that tax liability.

A special “wash sale” rule may apply to a non-U.S. shareholder who owns any class of our shares if (a) the non-U.S. shareholder owns more than 5% of that class of shares at any time during the one-year period ending on the date of the distribution described below, or (b) that class of our shares is not, within the meaning of applicable Treasury regulations, “regularly traded” on a domestic “established securities market” such as the NYSE.  Although there can be no assurance in this regard, we believe that our common shares have been and will remain “regularly traded” on a domestic “established securities market” within the meaning of applicable Treasury regulations, all as discussed above; however, we can provide no assurance that our shares will continue to be “regularly traded” on a domestic “established securities market” in future taxable years.  We anticipate this wash sale rule will apply, if at all, only(a) to a non-U.S. shareholder that owns more than 10% (5% for dispositions before December 18, 2015) of either our common shares or any class of our preferred shares or (b) if the particular class of our shares were to be no longer “regularly traded.”Such a non-U.S. shareholder will be treated as having made a “wash sale” of our shares if it (a) disposes of an interest in our shares during the thirtydays preceding the ex-dividend date of a distribution by us that, but for such disposition, would have been treated by the non-U.S. shareholder in whole or in part as gain from the sale or exchange of a USRPI, and then (b) acquires or enters into a contract to acquire a substantially identical interest in our shares, either actually or constructively through a related party, during the sixty-oneday period beginning thirtydays prior to the ex-dividend date.  In the event of such a wash sale, the non-U.S. shareholder will have gain from the sale or exchange of a USRPI in an amount equal to the portion of the distribution that, but for the wash sale, would have been a gain from the sale or exchange of a USRPI.  As discussed above, a non-U.S. shareholder’s gain from the sale or exchange of a USRPI can trigger increased United States taxes, such as the branch profits tax applicable to non-U.S. corporations, and increased United States tax filing requirements.

If for any taxable year we designate capital gain dividends for our shareholders, then a portion of the capital gain dividends we designate will be allocated to the holders of a particular class of shares on a percentage basis equal to the ratio of the amount of the total dividends paid or made available for the year to the holders of that class of shares to the total dividends paid or made available for the year to holders of all outstanding classes of our shares.

Tax treaties may reduce the withholding obligations on our distributions.  Under some treaties, however, rates below

33

30% that are applicable to ordinary income dividends from United States corporations may not apply to ordinary income dividends from a REIT or may apply only if the REIT meets specified additional conditions.  A non-U.S. shareholder must generally use an applicable IRS Form W-8, or substantially similar form, to claim tax treaty benefits.  If the amount of tax withheld with respect to a distribution to a non-U.S. shareholder exceeds the shareholder’s United States federal income tax liability with respect to the distribution, the non-U.S. shareholder may file for a refund of the excess from the IRS.  The 35% withholding tax rate discussed above on some capital gain dividends corresponds to the maximum income tax rate applicable to corporate non-U.S. shareholders but is higher than the current preferential maximum rates on capital gains generally applicable to noncorporate non-U.S. shareholders.  Treasury regulations also provide special rules to determine whether, for purposes of determining the applicability of a tax treaty, our distributions to a non-U.S. shareholder that is an entity should be treated as paid to the entity or to those owning an interest in that entity,and whether the entity or its owners are entitled to benefits under the tax treaty.  In the case of any deemed or constructive distribution ora distribution in kind,  the applicable withholding agent may collect the amount required to be withheld by reducing to cash for remittance to the IRS a sufficient portion of the property that the non-U.S. shareholder would otherwise receive or own if the cash portion of any such distribution is not sufficient to cover the withholding liability, and the non-U.S. shareholder may bear brokerage or other costs for this withholding procedure.

Non-U.S. shareholders should generally be able to treat amounts we designate as retained but constructively distributed capital gains in the same manner as actual distributions of capital gain dividends by us.  In addition, a non-U.S. shareholder should be able to offset as a credit against its federal income tax liability the proportionate share of the tax paid by us on such retained but constructively distributed capital gains.  A non-U.S. shareholder may file for a refund from the IRS for the amount that the non-U.S. shareholder’s proportionate share of tax paid by us exceeds its federal income tax liability on the constructively distributed capital gains.

If our shares are not USRPIs, then a non-U.S. shareholder’s gain on the sale of these shares generally will not be subject to United States federal income taxation, except that a nonresident alien individual who was in the United States for 183 days or more during the taxable year may be subject to a 30% tax on this gain.  Our shares will not constitute a USRPI if we are a “domestically controlled REIT.”  A domestically controlled REIT is a REIT in which at all times during the preceding five-year period less than 50% of the fair market value of the outstanding shares was directly or indirectly held by foreign persons.  From and after December 18, 2015, a person who at all relevant times holds less than 5% of a REIT’s shares that are regularly traded on an established securities market in the United States is deemed to be a U.S. person in making the determination of whether a REIT is domestically controlled, unless the REIT has actual knowledge that the person is not a U.S. person.  Other presumptions apply in making the determination with respect to other classes of REIT shareholders.  As a result of applicable presumptions, we expect to be able to demonstrate from and after December 18, 2015 that we are less than 50% foreign owned.  For periods prior to December 18, 2015, we believe that we were less than 50% foreign owned, but that may not be possible to demonstrate.  Accordingly, we can provide no assurance that we have been or will remain a domestically controlled REIT, particularly if that determination includes the period before December 18, 2015, when the presumptions described above did not apply.  Even if we are not a domestically controlled REIT, a non-U.S. shareholder’s gain on the sale of our shares will not be subject to United States federal income taxation as a sale of a USRPI,if that class of shares is “regularly traded,” as defined by applicable Treasury regulations, on an established securities market such as the NYSE, and the non-U.S. shareholder has at all times during the preceding five years owned 10% (5% for dispositions before December 18, 2015) or less by value of that class of shares.  In this regard, because the shares held by others may be redeemed,a non-U.S. shareholder’s percentage interest in a class of our shares may increase even if it acquires no additional shares in that class.  If a  gain on the sale of our shares is subject to United States federal income taxation under these rules, the non-U.S. shareholder will generally be subject to the same treatment as a U.S. shareholder with respect to its gain (subject to any applicable alternative minimum tax and a special alternative minimum tax in the case of nonresident alien individuals) and will be required to file a United States federal income tax return reporting that gain.  A purchaser of our shares from a non-U.S. shareholder will not be required to withhold on the purchase price if the purchased shares are regularly traded on an established securities market or if we are a domestically controlled REIT.  Otherwise, a purchaser of our shares from a non-U.S. shareholder may be required to withhold 15% (10% for dispositions on or before February 16, 2016) of the purchase price paid to the non-U.S. shareholder and to remit the withheld amount to the IRS.

Information Reporting, Backup Withholding, and Foreign Account Withholding

34

Information reporting, backup withholding, and foreign account withholding may apply to distributions or proceeds paid to our shareholders under the circumstances discussed below.  If a shareholder is subject to backup or other United States federal income tax withholding, then the applicable withholding agent will be required to withhold the appropriate amount with respect to a deemed or constructive distribution or a distribution in kindeven though there is insufficient cash from which to satisfy the withholding obligation.  To satisfy this withholding obligation, the applicable withholding agent may collect the amount of United States federal income tax required to be withheld by reducing to cash for remittance to the IRS a sufficient portion of the property that the shareholder would otherwise receive or own, and the shareholder may bear brokerage or other costs for this withholding procedure.

The backup withholding rate is currently 28%.  Amounts withheld under backup withholding are generally not an additional tax and may be refunded by the IRS or credited against the shareholder’s federal income tax liability.  A U.S. shareholder may be subject to backup withholding when it receives distributions on our shares or proceeds upon the sale, exchange, redemption, retirement or other disposition of our shares, unless the U.S. shareholder properly executes, or has previously properly executed, under penalties of perjury an IRS Form W-9 or substantially similar form that:

· provides the U.S. shareholder’s correct taxpayer identification number; and

· certifies that the U.S. shareholder is exempt from backup withholding because it comes within an enumerated exempt category, it has not been notified by the IRS that it is subject to backup withholding, or it has been notified by the IRS that it is no longer subject to backup withholding.

If the U.S. shareholder has not provided and does not provide its correct taxpayer identification number on an IRS Form W-9 or substantially similar form, it may be subject to penalties imposed by the IRS, and the applicable withholding agent may have to withhold a portion of any distributions or proceeds paid to such U.S. shareholder.  Unless the U.S. shareholder has established on a properly executed IRS Form W-9 or substantially similar form that it comes within an enumerated exempt category, distributions or proceeds on our shares paid to it during the calendar year, and the amount of tax withheld, if any, will be reported to it and to the IRS.

Distributions on our shares to a non-U.S. shareholder during each calendar year and the amount of tax withheld, if any, will generally be reported to the non-U.S. shareholder and to the IRS.  This information reporting requirement applies regardless of whether the non-U.S. shareholder is subject to withholding on distributions on our shares or whether the withholding was reduced or eliminated by an applicable tax treaty.  Also, distributions paid to a non-U.S. shareholder on our shares will generallybe subject to backup withholding, unless the non-U.S. shareholder properly certifies to the applicable withholding agent its non-U.S. shareholder status on anapplicable IRS Form W-8 or substantially similar form.  Information reporting and backup withholding will not apply to proceeds a non-U.S. shareholder receives upon the sale, exchange, redemption, retirement or other disposition of our shares, if the non-U.S. shareholder properly certifies its non-U.S. shareholder status on an applicable IRS Form W-8 or substantially similar form.  Even without having executed an applicableIRS Form W-8 or substantially similar form, however, in some cases information reporting and backup withholding will not apply to proceeds that a non-U.S. shareholder receives upon the sale, exchange, redemption, retirement or other disposition of our shares if the non-U.S. shareholder receives those proceeds through a broker’s foreign office.

Non-United States financial institutions and other non-United States entities are subject to diligence and reporting requirements for purposes of identifying accounts and investments held directly or indirectly by United States persons.  The failure to comply with these additional information reporting, certification and other requirements could result in a 30% withholding tax on applicable payments to non-United States persons.  In particular, a payee that is a foreign financial institution that is subject to the diligence and reporting requirements described above must enter into an agreement with the United States Department of the Treasury requiring, among other things, that it undertake to identify accounts held by “specified United States persons” or “United States owned foreign entities” (each as defined in the IRC), annually report information about such accounts, and withhold 30% on applicable payments to noncompliant foreign financial institutions and account holders.  Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States with respect to these requirements may be subject to different rules.  The foregoing withholding regimegenerally appliesto payments of dividends on our shares, andis expected to generally applyto other “withholdable payments” (including payments of gross proceeds from a sale or other disposition of our shares) made after December 31, 2018.  In general, to avoid withholding, any non-United States intermediary through which a shareholder owns our shares

35

must establish its compliance with the foregoing regime, and a non-U.S. shareholder must provide certain documentation (usually an applicable IRS Form W-8) containing information about its identity, its status, and if required, its direct and indirect U.S. owners.  Non-U.S. shareholders and shareholders who hold our shares through a non-United States intermediary are encouraged to consult with their own tax advisor regarding foreign account tax compliance.

Other Tax Considerations

Our tax treatment and that of our shareholders may be modified by legislative, judicial or administrative actions at any time, which actions may be retroactive in effect.  The rules dealing with federal income taxation are constantly under review by the United States Congress, the IRS and the United States Department of the Treasury, and statutory changes, new regulations, revisions to existing regulations and revised interpretations of established concepts are issued frequently.  Likewise, the rules regarding taxes other than United States federal income taxes may also be modified.  No prediction can be made as to the likelihood of passage of new tax legislation or other provisions, or the direct or indirect effect on us and our shareholders.  Revisions to tax laws and interpretations of these laws could adversely affect our ability to qualify and be taxed as a REIT, as well as the tax or other consequences of an investment in our shares.  We and our shareholders may also be subject to taxation by state, local or other jurisdictions, including those in which we or our shareholders transact business or reside.  These tax consequences may not be comparable to the United States federal income tax consequences discussed above.

ERISA PLANS, KEOGH PLANS AND INDIVIDUAL RETIREMENT ACCOUNTS

General Fiduciary Obligations

Fiduciaries of a pension, profit‑sharing or other employee benefit plan subject to Title I of the Employee Retirement Income Security Act of 1974, as amended, or ERISA, must consider whether:

· their investment in our shares or other securities satisfies the diversification requirements of ERISA;

· the investment is prudent in light of possible limitations on the marketability of our shares;

· they have authority to acquire our shares or other securities under the applicable governing instrument and Title I of ERISA; and

· the investment is otherwise consistent with their fiduciary responsibilities.

Trustees and other fiduciaries of an ERISA plan may incur personal liability for any loss suffered by the plan on account of a violation of their fiduciary responsibilities. In addition, these fiduciaries may be subject to a civil penalty of up to 20% of any amount recovered by the plan on account of a violation. Fiduciaries of any individual retirement account or annuity, or IRA, Roth IRA, tax‑favored account (such as an Archer MSA, Coverdell education savings account or health savings account), Keogh Plan or other qualified retirement plan not subject to Title I of ERISA, or non‑ERISA plans, should consider that the plan may only make investments that are authorized by the appropriate governing instrument.

Fiduciaries considering an investment in our securities should consult their own legal advisors if they have any concern as to whether the investment is consistent with the foregoing criteria or is otherwise appropriate. The sale of our securities to an ERISA or non‑ERISA plan is in no respect a representation by us or any underwriter of the securities that the investment meets all relevant legal requirements with respect to investments by plans generally or any particular plan, or that the investment is appropriate for plans generally or any particular plan.

Prohibited Transactions

Fiduciaries of ERISA plans and persons making the investment decision for an IRA or other non‑ERISA plan should consider the application of the prohibited transaction provisions of ERISA and the IRC in making their investment decision. Sales and other transactions between an ERISA or non‑ERISA plan, and persons related to it, are prohibited transactions. The particular facts concerning the sponsorship, operations and other investments of an ERISA plan or non‑ERISA plan may cause a wide range of other persons to be treated as disqualified persons or parties in interest with

36

respect to it. A prohibited transaction, in addition to imposing potential personal liability upon fiduciaries of ERISA plans, may also result in the imposition of an excise tax under the IRC or a penalty under ERISA upon the disqualified person or party in interest with respect to the plan. If the disqualified person who engages in the transaction is the individual on behalf of whom an IRA or Roth IRA is maintained or his beneficiary, the IRA or Roth IRA may lose its tax‑exempt status and its assets may be deemed to have been distributed to the individual in a taxable distribution on account of the prohibited transaction, but no excise tax will be imposed. Fiduciaries considering an investment in our securities should consult their own legal advisors as to whether the ownership of our securities involves a prohibited transaction.

“Plan Assets” Considerations

The United States Department of Labor has issued a regulation defining “plan assets.” The regulation generally provides that when an ERISA or non‑ERISA plan acquires a security that is an equity interest in an entity and that security is neither a “publicly offered security” nor a security issued by an investment company registered under the Investment Company Act of 1940, as amended, the ERISA plan’s or non‑ERISA plan’s assets include both the equity interest and an undivided interest in each of the underlying assets of the entity, unless it is established either that the entity is an operating company or that equity participation in the entity by benefit plan investors is not significant.

Each class of our shares (that is, our common shares and any class of preferred shares that we may issue) must be analyzed separately to ascertain whether it is a publicly offered security. The regulation defines a publicly offered security as a security that is “widely held,” “freely transferable” and either part of a class of securities registered under the Exchange Act, or sold under an effective registration statement under the Securities Act of 1933, as amended, provided the securities are registered under the Exchange Act within 120 days after the end of the fiscal year of the issuer during which the offering occurred. Each class of our outstanding shares has been registered under the Exchange Act within the necessary time frame to satisfy the foregoing condition.

The regulation provides that a security is “widely held” only if it is part of a class of securities that is owned by 100 or more investors independent of the issuer and of one another. However, a security will not fail to be “widely held” because the number of independent investors falls below 100 subsequent to the initial public offering as a result of events beyond the issuer’s control. We believe our common shares have been and will remain widely held, and we expect the same to be true of any class of preferred shares that we may issue, but we can give no assurances in this regard.

The regulation provides that whether a security is “freely transferable” is a factual question to be determined on the basis of all relevant facts and circumstances. The regulation further provides that, where a security is part of an offering in which the minimum investment is $10,000 or less, some restrictions on transfer ordinarily will not, alone or in combination, affect a finding that these securities are freely transferable. The restrictions on transfer enumerated in the regulation as not affecting that finding include:

· any restriction on or prohibition against any transfer or assignment that would result in a termination or reclassification for federal or state tax purposes, or would otherwise violate any state or federal law or court order;

· any requirement that advance notice of a transfer or assignment be given to the issuer and any requirement that either the transferor or transferee, or both, execute documentation setting forth representations as to compliance with any restrictions on transfer that are among those enumerated in the regulation as not affecting free transferability, including those described in the preceding clause of this sentence;

· any administrative procedure that establishes an effective date, or an event prior to which a transfer or assignment will not be effective; and

· any limitation or restriction on transfer or assignment that is not imposed by the issuer or a person acting on behalf of the issuer.

We believe that the restrictions imposed under our declaration of trust on the transfer of shares do not result in  the failure of our shares to be “freely transferable.” Furthermore, we believe that there exist no other facts or circumstances

37

limiting the transferability of our shares that are not included among those enumerated as not affecting their free transferability under the regulation, and we do not expect or intend to impose in the future, or to permit any person to impose on our behalf, any limitations or restrictions on transfer that would not be among the enumerated permissible limitations or restrictions.

Assuming that each class of our shares will be “widely held” and that no other facts and circumstances exist that restrict transferability of these shares, our counsel, Sullivan & Worcester LLP, is of the opinion that our shares will not fail to be “freely transferable” for purposes of the regulation due to the restrictions on transfer of our shares under our declaration of trust and that under the regulation each class of our currently outstanding shares is publicly offered and our assets will not be deemed to be “plan assets” of any ERISA plan or non‑ERISA plan that acquires our shares in a public offering. This opinion is conditioned upon certain assumptions and representations, as discussed above in “United States Federal Income Tax Considerations—Taxation as a REIT.”

Item 1A.  Risk Factors.

Our business is subject to a number of risks and uncertainties. The risks described below may not be the only risks we face but are risks we believe material at this time. Additional risks that we do not yet know of, or that we currently think are immaterial, may also impair our business operations or financial results. If any of the events or circumstances described below occurs, our business, financial condition or results of operations and the trading price of our securities could decline. Investors and prospective investors should consider the following risks and the information contained under the heading “Warning Concerning Forward Looking Statements” before deciding whether to invest in our securities.

Risks Related to Our Tenants and Managers

Financial and other difficulties at Five Star could adversely affect us.

As of December 31, 2015, Five Star accounted for approximately 30.8% of our total annualized rental income and operated approximately 46.3% of our properties, at cost (less impairments). Five Star has not been consistently profitable since it became a public company in 2001, and it currently has limited resources and substantial lease obligations to us and others. Although Five Star has access to a $150.0 million revolving credit facility, that facility currently matures in April 2016, andFive Star has notified the lenders under that facility of its intent to exercise its second one year option to extend the maturity date of that facility to April 2017, subject to the payment of an extension fee and meeting certain other conditions, in the longer term, Five Star may be unable to maintain that facility or obtain a replacement facility on similar or more favorable terms.

Five Star’s business is subject to a number of risks, including the following:

· Five Star has high operating leverage. A small percentage decline in Five Star’s revenues or increase in Five Star’s expenses could have a material adverse impact on Five Star’s operating results;

· Medicare and Medicaid payments account for some of Five Star’s total revenues. A reduction in Medicare and Medicaid payment rates or a failure of these payment rates to match Five Star’s costs may materially and adversely affect Five Star;

· Current general economic conditions may adversely affect Five Star’s operations. Inflation, high levels of unemployment, housing market declines, market declines affecting the value and liquidity of other personal assets, or other circumstances affecting the ability of seniors or their families to pay for Five Star’s services could have a material adverse effect on Five Star’s business, financial condition and results of operations. In addition, housing price declines and reduced home mortgage financing availability have negatively affected the U.S. housing market. If seniors have a difficult time selling their homes, fewer seniors may relocate to Five Star’s senior living communities or finance their stays at Five Star’s senior living communities with their private resources;

38

· Private third party payers’, such as insurance companies’, continued efforts to reduce healthcare costs could adversely affect Five Star;

· Provisions of the ACA could reduce Five Star’s income and increase its costs;

· Increases in labor costs could have a material adverse effect on Five Star;

· Five Star’s business is subject to extensive regulation, which increases its costs and may result in losses;

· The nature of Five Star’s business exposes it to litigation risks. Five Star has been, is currently, and expects in the future to be involved in claims, lawsuits, and regulatory and other governmental audits, investigations and proceedings arising in the ordinary course of its business, some of which may involve material amounts;

· Increases in liability insurance costs could have a material adverse effect on Five Star; and

· Five Star’s growth strategy, which includes the acquisition of senior living communities, may not succeed and may result in declines in profitability or recurring losses.

If Five Star’s operations are unprofitable, it may default in its rent obligations to us or we may realize reduced income from our managed senior living communities, and, if Five Star fails to provide quality services at the senior living communities we own, our income from these communities may be adversely affected. Furthermore, if we were required to replace Five Star as our tenant or manager, significant disruptions could be experienced at the affected senior living communities, which could reduce our income and cash flow from, and the value of, those communities.

Increases in labor costs at our managed senior living communities may have a material adverse effect on us.

Wages and employee benefits incurred at our managed senior living communities represent a significant part of our senior living operating expenses. Five Star, as manager of a majority of these communities, and the other third party manager we have retained, compete with other senior living community operators, among others, to attract and retain qualified personnel responsible for the day to day operations of these communities. The market for qualified nurses, therapists and other healthcare professionals is highly competitive and periodic or geographic area shortages of such healthcare professionals may require our managers to increase the wages and benefits offered to their employees in order to attract and retain such personnel or to utilize temporary personnel at an increased cost. In addition, employee benefit costs, including employee health insurance and workers’ compensation insurance costs, have materially increased in recent years and, as discussed above, we cannot predict the future impact of the ACA on the cost of employee health insurance. Although Five Star determines its employee health insurance and workers’ compensation self insurance reserves with guidance from third party professionals, such reserves may nonetheless be inadequate. Increasing employee health insurance and workers’ compensation insurance costs of our managers and increasing self insurance reserves for labor related insurance may materially and adversely affect our earnings from our managed senior living communities.

We cannot assure that labor costs at our managed senior living communities will not increase or that any increases will be recovered by corresponding increases in the rates charged to residents or otherwise. Any significant failure by our managers to control labor costs or to pass any increases on to residents through rate increases at our managed senior living communities could have a material adverse effect on our business, financial condition and results of operations.

Termination of assisted living resident agreements and resident attrition could adversely affect our revenues and earnings at our leased and managed senior living communities.

State regulations governing assisted living communities typically require a written resident agreement with each resident. Most of these regulations also require that each resident have the right to terminate these assisted living resident agreements for any reason on reasonable notice. Consistent with these regulations, most of the resident agreements at our leased and managed senior living communities allow residents to terminate their agreements on 30 days’ notice. Thus, we

39

and our tenants and managers may be unable to contract with assisted living residents to stay for longer periods of time, unlike typical apartment leasing arrangements that involve lease agreements with terms of up to a year or longer. If a large number of residents elected to terminate their resident agreements at or around the same time, our revenues and earnings from our leased and managed senior living communities could be materially and adversely affected. In addition, the advanced ages of senior living residents at our leased and managed senior living communities make the resident turnover rate in these senior living communities difficult to predict.

The trend for senior citizens to delay moving to senior living residences until they reach an older age or require greater care may increase operating costs, reduce occupancy and increase resident turnover rate at our senior living communities.

Senior citizens have been increasingly delaying their moves to senior living residences until they reach an older age, including at our senior living communities. If this trend continues, the occupancy rate at our senior living communities may decline and the resident turnover rate at those communities may increase. Further, older aged persons may have greater care needs and require higher acuity services, which may increase our and our tenants’ cost of business, expose us and our tenants’ to additional liability or result in lost business and earlier stays at our senior living communities if our managers or tenants are not able to provide the requisite care services or fail to adequately provide those services.

Some of our tenants and managers are faced with significant potential litigation and rising insurance costs that not only affect their ability to obtain and maintain adequate liability and other insurance, but also may affect their ability to fulfill insurance, indemnification and other obligations to us under their leases and management agreements and to pay rents or to generate and pay minimum and other returns.

In some states, advocacy groups monitor the quality of care at SNFs and assisted and independent living communities, and these groups have brought litigation against operators and owners. Also, in several instances, private litigation by SNF patients, assisted and independent living community residents or their legal representatives have succeeded in winning very large damage awards for alleged neglect. The effect of this litigation and potential litigation has been to materially increase the costs of monitoring and reporting quality of care compliance incurred by some of our tenants and managers. The cost of liability and medical malpractice insurance has increased and may continue to increase so long as the present litigation environment in many parts of the United States continues. This may affect the ability of some of our tenants and managers to obtain and maintain adequate liability and other insurance and manage their related risk exposures. In addition to causing some of our tenants and managers to be unable to fulfill their insurance, indemnification and other obligations to us under their leases and management agreements and thereby potentially exposing us to those risks, these litigation risks and costs could cause some of our tenants and managers to become unable to pay rents due to us or generate and pay minimum and other returns to us.

The failure of our tenants, our managers or us to comply with laws relating to the operation of our leased and managed communities may have a material adverse effect on the ability of our tenants to pay us rent, the profitability of our managed senior living communities and the values of our properties.

We and our tenants and managers are subject to or impacted by extensive, frequently changing federal, state and local laws and regulations. Some of these laws and regulations include: state and local licensure laws; laws protecting consumers against deceptive practices; laws relating to the operation of our properties and how our tenants and managers conduct their operations, such as health and safety, fire and privacy laws; federal and state laws affecting communities that participate in Medicaid; federal and state laws affecting SNFs, clinics and other healthcare facilities that participate in both Medicare and Medicaid that mandate allowable costs, pricing, reimbursement procedures and limitations, quality of services and care, food service and physical plants; resident rights laws (including abuse and neglect laws) and fraud laws; anti-kickback and physician referral laws; the ADA and similar state and local laws; and safety and health standards set by the Occupational Safety and Health Administration. We and our tenants and managers expend significant resources to maintain compliance with these laws and regulations, and responding to any allegations of noncompliance also results in the expenditure of significant resources. Moreover, the failure of our managers to properly operate our senior living communities could result in fines or other sanctions which may materially and adversely impact our ability to obtain or renew licenses for our managed communities.

If we or our tenants or managers fail to comply with any applicable legal requirements, or are unable to cure deficiencies, certain sanctions may be imposed and, if imposed, may 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. Further, changes in the

40

applicable regulatory framework could have a material adverse effect on the ability of our tenants to pay us rent, the profitability of our managed senior living communities and the values of our properties.

We and our tenants and managers are required to comply with federal and state laws governing the privacy, security, use and disclosure of individually identifiable information, including financial information and protected health information. Under HIPAA, we and our tenants and managers are required to comply with the HIPAA privacy rule, security standards, and standards for electronic healthcare transactions. State laws also govern the privacy of individual health information, and these laws are, in some jurisdictions, more stringent than HIPAA. Other federal and state laws govern the privacy of individually identifiable information.

If we or our tenants or managers fail to comply with applicable federal or state standards, we or they could be subject to civil sanctions and criminal penalties, which could materially and adversely affect our business, financial condition and results of operations.

We may incur significant costs complying with the ADA and similar laws.

Under the ADA, places of public accommodation and/or commercial facilities must meet federal requirements related to access and use by disabled persons. We may be required to make substantial capital expenditures at our properties to comply with this law. In addition, non-compliance could result in the imposition of fines or an award of damages to private litigants.

A number of additional federal, state, and local laws and regulations exist regarding access by disabled persons. These regulations may require modifications to our properties or may affect future renovations. These expenditures may have an adverse impact on overall returns on our investments.

The operations of some of our communities are dependent upon payments from the Medicare and Medicaid programs.

As of December 31, 2015, approximately 97% of our NOI was generated from properties where a majority of the revenue is derived from private resources, and the remaining 3% of our NOI was generated from properties where a majority of the revenue was derived from Medicare and Medicaid reimbursements. Operations at most of our Medicare and Medicaid dependent properties currently produce sufficient cash flow to pay our allocated rents or our minimum returns, but operations at certain of these properties do not. Even at properties where less than a majority of the NOI comes from Medicare or Medicaid payments, a reduction in such payments could materially adversely affect profits of, or result in losses to, our tenants or managers. With the background of the current and projected federal budget deficit and other federal priorities and continued challenging state fiscal conditions, there have been numerous recent legislative and regulatory actions or proposed actions with respect to federal Medicare and state Medicaid rates and federal payments to states for Medicaid programs. For further information regarding such programs, see elsewhere in this Annual Report on Form 10-K, including under the caption “Business—Government Regulation and Reimbursement” in Part 1, Item 1 of this Annual Report on Form 10-K, and under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Impact of Government Reimbursement” in Part II, Item 7 of this Annual Report on Form 10-K. If and to the extent Medicare or Medicaid rates are reduced from current levels, or if rate increases are less than increases in operating costs, such changes could have a material adverse effect on the ability of our tenants to pay us rent, the profitability of our managed senior living communities and the values of our properties. In addition, the revenues that we or our tenants receive from Medicare and Medicaid may be subject to statutory and regulatory changes, retroactive rate adjustments, recovery of program overpayments or set offs, administrative rulings and policy interpretations, and payment delays, any of which could have a material adverse effect on the ability of our tenants to pay us rent, the profitability of our managed senior living communities and the values of our properties.

Provisions of the ACA could adversely affect us or our tenants and managers.

The ACA contains insurance changes, payment changes and healthcare delivery systems changes that have affected, and will continue to affect, us, our tenants and managers. Examples of these, and other information regarding such programs, are provided below as well as under the caption “Business—Government Regulation and Reimbursement” in Part 1, Item 1 of this Annual Report on Form 10-K and under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Impact of Government Reimbursement” in Part II, Item 7 of this Annual Report on Form 10-K.

41

Provisions of the ACA include multiple reductions to the annual market basket updates for inflation that may result in SNF Medicare payment rates being less than for the preceding fiscal year. We are unable to predict how potential Medicare rate reductions under the ACA will affect our tenants’ and our managers’ future financial results of operations; however, the effect may be adverse and material and hence adverse and material to our future financial condition and results of operations.

The ACA also established an Independent Payment Advisory Board to submit legislative proposals to Congress and take other actions with a goal of reducing Medicare spending growth. When and if such spending reductions take effect, they may be adverse and material to our tenants’ ability to pay rent to us, the profitability of our managed senior living communities and the values of our properties. The ACA includes other changes that may affect us, our tenants and our managers, such as enforcement reforms and Medicare and Medicaid program integrity control initiatives, new compliance, ethics and public disclosure requirements, initiatives to encourage the development of home and community based long term care services rather than institutional services under Medicaid, value based purchasing plans and a Medicare post acute care pilot program to develop and evaluate making a bundled payment for services, including hospital, physician and SNF services, provided during an episode of care.

In June 2012, the U.S. Supreme Court upheld two major provisions of the ACA—the individual mandate, which requires most Americans to maintain health insurance or to pay a penalty, and the Medicaid expansion, which requires states to expand their Medicaid programs by 2014 to cover all individuals under the age of 65 with incomes not exceeding 133% of the federal poverty level. In upholding the Medicaid expansion, the U.S. Supreme Court held that it violated the U.S. Constitution as drafted but remedied the violation by modifying the expansion to preclude the Secretary of HHS from withholding existing federal Medicaid funds from states that fail to comply with Medicaid expansion, instead allowing the Secretary only to deny new expansion funding. Under 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 January 12, 2016, 31 states plus the District of Columbia had elected to expand Medicaid eligibility as provided under the ACA, 16 states had elected not to broaden Medicaid eligibility, and three remained undecided; those states choosing not to participate in Medicaid expansion are forgoing the federal funds that would otherwise be available for that purpose.

In June 2015, the U.S. Supreme Court decided that income tax credits under the ACA are available to individuals who purchase health insurance on an exchange created by the federal government, in the same way such credits are available to individuals who purchase health insurance on an exchange created by a state.  Such subsidies provide certain eligible taxpayers with the ability to purchase or maintain health insurance.

Changes implemented under the ACA resulting in reduced payments for services or the failure of Medicare, Medicaid or insurance payment rates to cover increasing costs could adversely and materially affect the ability of our tenants to pay rent to us, the profitability of certain of our managed senior living communities and the values of our properties.

The U.S. economy’s recovery to date from its most recent recession has been slow, unsteady and incomplete.

The U.S. economy’s recovery to date from its most recent recession has been slow, unsteady and incomplete, which has created volatile market conditions. While the markets had been showing signs of stabilization and growth, new challenges have arisen, including uncertain U.S. Federal Reserve policy regarding the timing and amount of future increases in interest rates and the risk that declining overseas markets may hinder the growth of the U.S. economy. It remains unclear whether the U.S. economy will be able to withstand these market challenges and global uncertainty and achieve meaningful and sustained growth. Economic weakness in the U.S. economy generally or a new recession would likely adversely affect our financial condition and that of our tenants, and could impact the ability or willingness of our tenants to renew our leases or pay rent to us.

We are limited in our ability to operate or manage our properties and are thus dependent on the managers and tenants of our properties.

42

Because federal income tax laws restrict REITs and their subsidiaries from operating or managing health care facilities, we do not operate or manage our senior living communities. Instead, we lease nearly all of our senior living communities to operating companies or to our subsidiaries that qualify as TRSs under the IRC. We have retained Five Star and another third party manager to operate and manage our senior living communities that are leased to our subsidiaries. Our income from our properties may be adversely affected if our managers or tenants fail to provide quality services and amenities to residents or if they fail to maintain quality services. While we monitor our managers’ and tenants’ performances and apply asset management strategies and discipline, we have limited recourse under our management agreements and leases if we believe that the managers or tenants are not performing adequately. Failure by our managers or tenants to fully perform the duties agreed to in our management agreements and leases could adversely affect our results of operations. In addition, our managers and tenants operate, and in some cases own or have invested in, properties that compete with our properties, which may result in conflicts of interest.  Also, fees paid to our managers are often set as a percentage of gross revenues rather than profits. As a result, our managers and tenants have in the past made, and may in the future make, decisions regarding competing properties or our properties’ operations that seek to increase their fees but which may not be in our best interests.

Risks Related to Our Business

We may be unable to access the capital necessary to repay our debts, invest in our properties or fund acquisitions.

To retain our qualification for taxation as a REIT, we are required to distribute at least 90% of our annual REIT taxable income (excluding capital gains) and satisfy a number of organizational and operational requirements to which REITs are subject. Accordingly, we generally will not be able to retain sufficient cash from operations to repay debts, invest in our properties or fund acquisitions. Our business and growth strategies depend, in part, upon our ability to raise additional capital at reasonable costs to repay our debts, invest in our properties and fund acquisitions. Because of the volatility in the availability of capital to businesses on a global basis and the increased volatility in most debt and equity markets generally, our ability to raise reasonably priced capital is not guaranteed; we may be unable to raise reasonably priced capital because of reasons related to our business, market perceptions of our prospects, the terms of our indebtedness or for reasons beyond our control, such as market conditions. If we are unable to raise reasonably priced capital, our business and growth strategies may fail and we may be unable to remain qualified for taxation as a REIT.

Increasing interest rates may adversely affect usand the value of an investment in our shares.

Since the most recent recession, the U.S. Federal Reserve has taken actions which have resulted in low interest rates prevailing in the marketplace for a historically long period of time. In December 2015, the U.S. Federal Reserve raised its benchmark interest rate by a quarter of a percentage point. Market interest rates may continue to increase and the increase may materially and negatively affect us. One of the factors that investors typically consider important in deciding whether to buy or sell our common shares is the distribution rate with respect to such shares relative to prevailing market interest rates. If market interest rates go up, investors may expect a higher distribution rate before investing in our common shares or may sell our common shares and seek alternate investments with a higher distribution rate. Sales of our common shares may cause a decline in the market prices of such shares, which would reduce our market capitalization and total shareholder return.

The potential negative impact on the value of our shares may increase our cost of capital, including decreasing the amount of equity and debt we may be able to raise, increasing the extent of dilution from any equity offering we may make or increasing the costs to us for any such equity or debt offering.

Amounts outstanding under our revolving credit facility and term loans require interest to be paid at variable interest rates. When interest rates increase, so will our interest costs, which could adversely affect our cash flow, our ability to pay principal and interest on our debt, our cost of refinancing our debt when it becomes due and our ability to make or sustain distributions to our shareholders. Additionally, if we choose to hedge our interest rate risk, we cannot assure that the hedge will be effective or that our hedging counterparty will meet its obligations to us.

An increase in interest rates could decrease the amount buyers may be willing to pay for our properties, thereby reducing the market value of our properties and limiting our ability to sell properties or to obtain mortgage financing

43

secured by our properties. Further, increased interest rates may effectively increase the cost of properties we acquire to the extent we utilize leverage for those acquisitions and may result in a reduction in our acquisitions to the extent we reduce the amount we offer to pay for properties, due to the effect of increased interest rates, to a price that sellers may not accept.

Our properties and their operations are subject to extensive regulations.

Various governmental authorities mandate certain physical characteristics of senior housing properties, clinics, other healthcare communities and biotech laboratories. Changes in laws and regulations relating to these matters may require significant expenditures. Our leases, other than our MOB leases, and our management agreements generally require our tenants or managers to maintain our properties in compliance with applicable laws and regulations, and we expend resources to monitor their compliance. However, our tenants or managers may neglect maintenance of our properties if they suffer financial distress. Under some of our leases, we have agreed to fund capital expenditures in return for rent increases and minimum returns due to us, with respect to our managed senior living communities increase by a defined percentage of the capital expenditures we fund at those communities. Our available financial resources or those of our tenants or managers may be insufficient to fund the expenditures required to operate our properties in accordance with applicable laws and regulations. If we fund these expenditures, our tenants’ financial resources may be insufficient to satisfy their increased rental payments to us or our managed senior living communities may fail to generate profits sufficient to fund our minimum returns.

Licensing, Medicare and Medicaid laws also require our tenants who operate senior living communities, hospitals, clinics and other healthcare communities to comply with extensive standards governing their operations. In addition, certain laws prohibit fraud by senior living operators, hospitals and other healthcare communities, including civil and criminal laws that prohibit false claims in Medicare, Medicaid and other programs and that regulate patient referrals. In recent years, the federal and state governments have devoted increasing resources to monitoring the quality of care at senior living communities and to anti‑fraud investigations in healthcare operations generally. The ACA also facilitates the DOJ’s ability to investigate allegations of wrongdoing or fraud at SNFs. When violations of anti‑fraud, false claims, anti-kickback or physician referral laws are identified, federal or state authorities may impose civil monetary damages, treble damages, repayment requirements and criminal sanctions. Healthcare communities may also be subject to license revocation or conditional licensure and exclusion from Medicare and Medicaid participation or conditional participation. When quality of care deficiencies or improper billing are identified, various laws may authorize civil money penalties or fines; the suspension, modification, or revocation of a license or Medicare/Medicaid participation; the suspension or denial of admissions of residents; the denial of payments in full or in part; the implementation of state oversight, temporary management or receivership; and the imposition of criminal penalties. We, our tenants and managers receive notices of potential sanctions from time to time, and governmental authorities impose such sanctions from time to time on our communities which our tenants and managers operate. If our tenants or managers are unable to cure deficiencies which have been identified or which are identified in the future, these sanctions may be imposed, and if imposed, may adversely affect our tenants’ ability to pay rents to us, our returns and our ability to identify substitute tenants or managers. Federal and state requirements for change in control of healthcare communities, including, as applicable, approvals of the proposed operator for licensure, CON, and Medicare and Medicaid participation, may also limit or delay our ability to find substitute tenants or managers. If any of our tenants or managers becomes unable to operate our properties, or if any of our tenants becomes unable to pay its rent or generate and pay our minimum returns because it has violated government regulations or payment laws, such incidents may trigger a default under their leases and management agreements with us and our or our tenants’ or managers’ credit agreements, and we may experience difficulty in finding a substitute tenant or manager or selling the affected property for a fair and commercially reasonable price, and the value of an affected property may decline materially.

Various laws administered by the FDA and other agencies regulate the operations of our tenants that operate biotech laboratories that develop, manufacture, market or distribute pharmaceuticals or medical devices. Once a product is approved, the FDA maintains oversight of the product and its developer and can withdraw its approval, recall products or suspend their production, impose or seek to impose civil or criminal penalties on the developer or take other actions for the developer’s failure to comply with regulatory requirements, including anti‑fraud, false claims, anti-kickback or physician referral laws. Other concerns affecting our biotech laboratory tenants include the potential for subsequent discovery of safety concerns and related litigation, ensuring that the product qualifies for reimbursement under Medicare, Medicaid or other federal or state programs, cost control initiatives of payment programs, the potential for litigation over

44

the validity or infringement of intellectual property rights related to the product, the eventual expiration of relevant patents and the need to raise additional capital. The cost of compliance with these regulations and the risks described in this paragraph, among others, could adversely affect the ability of our biotech laboratory tenants to pay rent to us.

We may be unable to grow our business by acquisitions and our acquisitions may not be successful.

An element of our business plan involves the acquisition of additional properties. Our ability to complete attractive acquisitions may be subject to risks associated with:

· competition from other investors, including publicly traded and private REITs, numerous financial institutions, individuals and public and private companies;

· contingencies in our acquisition agreements;

· the availability of financing; and

· the terms of our indebtedness.

Additionally, we might encounter unanticipated difficulties and expenditures relating to any acquired properties. For example:

· any failure to comply with licensing requirements at our managed senior living communities may prevent us from renewing licenses at senior living communities we own or prevent us from obtaining licenses at senior living communities we want to acquire;

· newly acquired properties might require significant management attention that would otherwise be devoted to our ongoing business;

· we might never realize the anticipated benefits of our acquisitions;

· notwithstanding pre-acquisition due diligence, we do not believe that it is possible to fully understand a property before it is owned and operated for an extended period of time, and we could acquire a property that contains undisclosed defects in design or construction;

· the market in which an acquired property is located may experience unexpected changes that adversely affect the property’s value;

· the occupancy of properties that we acquire may decline during our ownership, and rents or returns that are in effect or expected at the time a property is acquired may decline thereafter;

· property operating costs for our acquired properties may be higher than anticipated and our acquired properties may not yield expected returns;

· if we finance acquisitions using new debt or equity issuances, such financing may result in shareholder dilution; and

· we may acquire properties subject to liabilities and without any recourse, or with only limited recourse, for unknown liabilities such as liabilities for cleanup of undisclosed environmental contamination, claims by tenants, vendors, or other persons dealing with the former owners of the properties and claims for indemnification by general partners, directors, officers and others indemnified by the former owners of the properties.

45

For these reasons, among others, our business plan to acquire additional properties may not succeed or may cause us to experience losses.

We face significant competition and we may be unable to profit from our managed senior living communities.

We face significant competition for acquisition opportunities from other investors, including publicly traded and private REITs, numerous financial institutions, individuals and public and private companies. Because of competition, we may be unable to, or may pay a significantly increased purchase price to, acquire a desired property. Some of our competitors may have greater financial and other resources than we have.

In addition, our leased properties, particularly our MOBs, face competition for tenants. Some competing properties may be newer, better located or more attractive to tenants. Competing properties may have lower rates of occupancy than our properties, which may result in competing owners offering available space at lower rents than we offer at our properties. This competition may affect our ability to attract and retain tenants and may reduce the rents we are able to charge.

Furthermore, the managers of our managed senior living communities compete with numerous other companies that provide senior living services, including home healthcare companies and other real estate based service providers. Although some states require CONs to develop new SNFs and assisted living communities, these may not prevent or meaningfully reduce competition; moreover, there are fewer barriers to competition for home healthcare, for independent and assisted living services or for other real estate based services. We cannot assure that our managers will be able to attract a sufficient number of residents to our managed senior living communities at rates that would generate acceptable returns or that they will be able to attract employees and keep wages and other employee benefits, insurance costs and other operating expenses at levels which will allow our managed senior living communities to compete successfully or to operate profitably.

Increasing investor interest in healthcare related real estate may increase competition and reduce our growth.

Our business is highly competitive and we expect that it may become more competitive in the future. We compete with a number of publicly traded and private REITs, numerous financial institutions, individuals and public and private companies who are actively engaged in our business, some of which are larger and have a lower cost of capital than we do. In the past, periods of economic recession in the economy generally have sometimes caused some investors to focus on healthcare and healthcare real estate investments because some investors believe these types of investments may be less affected by general economic circumstances than most other investments. Further, in light of the currently low historical market interest rates and increased leverage utilized by financial and other buyers, purchase prices for properties have experienced increases resulting in lower rates of returns. These developments could result in increased competition for investments, fewer investment opportunities available to us and lower spreads over the cost of our capital, all of which would limit our ability to grow our business and improve our financial results.

Competition from new communities may adversely affect some of our communities.

In recent years, a significant number of new assisted living communities have been developed, and this increased development activity may continue in the future. In most states these communities are subject to less stringent regulations than SNFs and can operate with comparatively fewer personnel and at comparatively lower costs. As a result of offering newer accommodations at equal or lower costs, these assisted living properties and other senior living alternatives, including home healthcare, often attract persons who would have previously become SNF residents. Many of the residents attracted to new assisted living properties were the most profitable SNF patients, since they paid higher rates than Medicaid or Medicare would pay and they required less amounts of care. Historically, state requirements of obtaining CONs to develop new properties have somewhat reduced competition among SNFs; however, many states are eliminating or reducing these barriers. Also, there are few regulatory barriers to competition for home healthcare or for independent and assisted living services. These competitive factors have caused some SNFs which we own to decline in value. This decline may continue as assisted living communities or other elderly care alternatives, such as home healthcare, expand their businesses. Each of our tenants of our senior living communities faces similar risks. These competition risks may prevent our tenants and managers from maintaining or improving occupancy at our properties, which may increase the risk of

46

default under our leases and management agreements and adversely affect the profitability of our managed senior living communities.

When we renew leases or lease to new tenants of our MOBs our rents may decline and our expenses may increase and changes in tenants’ requirements for leased MOB space may adversely affect us.

When we renew leases or lease to new tenants of our MOBs we may receive less rent than we currently receive from existing tenants at our MOBs. Market conditions may require us to lower our rents to retain tenants at our MOBs. When we lease to new tenants or renew leases for our MOBs we may have to spend substantial amounts for leasing commissions, tenant improvements or other tenant inducements. Many of our leases for our MOBs are especially suited to the particular business of our tenants. Because these properties have been designed or physically modified for a particular tenant, if the current lease is terminated or not renewed, we may be required to renovate the property at substantial costs, decrease the rent we charge or provide other concessions in order to lease the property to another tenant. MOB tenants have been generally increasingly seeking to increase their space utilization under their leases, including reducing the amount of square footage per employee at leased properties, which may reduce the demand for leased space. If a significant number of such events occur, our income and cash flow may materially decline and our ability to make regular distributions to our shareholders may be jeopardized.

We may be unable to lease our properties when our leases expire.

Although we typically will seek to renew our leases with current tenants as these leases approach expiration, we cannot assure that we will be successful in doing so. If our tenants do not renew their leases, we may be unable to locate new tenants to maintain or increase the historical occupancy rates of, or rents from, our properties.

Ownership of real estate is subject to environmental and climate change risks.

Ownership of real estate is subject to risks associated with environmental hazards. We may be liable for environmental hazards at, or migrating from, our properties, including those created by prior owners or occupants, existing tenants or managers, abutters or other persons. Various federal and state laws impose liabilities upon property owners, such as us, for any environmental damages arising at, or migrating from, properties they own, and we cannot assure that we will not be held liable for environmental investigation and clean up at, or near, our properties, including at sites we own and lease to our tenants or managers. As an owner or previous owner of properties which contain environmental hazards, we also may be liable to pay damages to governmental agencies or third parties for costs and damages they incur arising from environmental hazards at, or migrating from, our properties. Moreover, the costs and damages which may arise from environmental hazards are often difficult to project and may be substantial.

We believe any asbestos in our buildings is contained in accordance with current regulations, and we have no current plans to remove it. If we removed the asbestos at our properties or demolished these properties, certain environmental regulations govern the manner in which the asbestos must be handled and removed, and we could incur substantial costs complying with such regulations.

There have recently been severe weather activities in different parts of the country that some observers believe evidence global climate change. Such severe weather that may result from climate change may have an adverse effect on individual properties we own. Further, the current political debate about climate change has resulted in various treaties, laws and regulations which are intended to limit carbon emissions. We believe these laws being enacted or proposed may cause energy costs at our properties to increase. Laws enacted to mitigate climate change may make some of our buildings obsolete or cause us to make material investments in our properties which could materially and adversely affect our financial condition and results of operations. For more information regarding climate change matters and their possible adverse impact on us, please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Impact of Climate Change.” in Part II, Item 7 of this Annual Report on Form 10-K.

47

Real estate ownership creates risks and liabilities.

In addition to the risks related to environmental hazards and climate change, our business is subject to other risks associated with real estate ownership, including:

· newly acquired properties might require significant management attention that would otherwise be devoted to our ongoing business;

· we might never realize the anticipated benefits of our acquisitions;

· notwithstanding pre acquisition due diligence, we do not believe that it is possible to fully understand a property before it is owned and operated for an extended period of time, and we could acquire a property that contains undisclosed defects in design or construction;

· the market in which the acquired property is located may experience unexpected changes that adversely affect the property’s value;

· the occupancy of properties that we acquire may decline during our ownership, and rents or returns that are in effect or expected at the time a property is acquired may decline thereafter;

· property operating costs for our acquired properties may be higher than anticipated and our acquired properties may not yield expected returns;

· if we finance acquisitions using new debt or equity issuances, such financing may result in shareholder dilution;

· we may acquire properties subject to liabilities and without any recourse, or with only limited recourse, for unknown liabilities such as liabilities for cleanup of undisclosed environmental contamination, claims by tenants, vendors, or other persons dealing with the former owners of the properties and claims for indemnification by general partners, directors, officers and others indemnified by the former owners of the properties.

· the illiquid nature of real estate markets, which limits our ability to sell our assets rapidly to respond to changing market conditions;

· the subjectivity of real estate valuations and changes in such valuations over time;

· property and casualty losses;

· costs that may be incurred relating to property maintenance and repair, and the need to make expenditures due to changes in governmental regulations, including the ADA;

· legislative and regulatory developments that may occur at the federal, state and local levels that have direct or indirect impact on the ownership, leasing and operation of our properties; and

· litigation incidental to our business.

We have a substantial amount of indebtedness and other obligations, which could adversely affect our financial condition, and we may incur additional debt.

As of December 31, 2015, we had $3.5 billion in debt outstanding, which was 51.0% of our total book capitalization. These obligations are substantial, could have important consequences to holders of our common shares and could limit our ability to obtain financing for working capital, capital expenditures, acquisitions, refinancing, lease

48

obligations or other purposes. They may also increase our vulnerability to adverse economic, market and industry conditions, limit our flexibility in planning for, or reacting to, changes in our business operations or to our industry overall, and place us at a disadvantage in relation to competitors that have lower debt levels. In addition, amounts outstanding under our revolving credit facility and term loans require interest to be paid at variable interest rates. When interest rates increase, so will our interest costs, which could adversely affect our cash flow, our ability to pay principal and interest on our debt and our cost of refinancing our debt when it becomes due. For further information regarding our exposure to risks associated with market changes in interest rates, please see elsewhere in this Annual Report on Form 10-K, including under the caption “Quantitative and Qualitative Disclosures About Market Risk.” Additionally, if we choose to hedge our interest rate risk, we cannot assure that the hedge will be effective or that our hedging counterparty will meet its obligations to us.  Any or all of the above events and factors could have an adverse effect on our results of operations and financial condition.

If we default under a loan, including any default in covenants contained in our revolving credit facility and term loan agreements or our senior unsecured notes indentures and their supplements, we may be in default under any other loan that has cross-default provisions, further borrowings under our existing revolving credit facility may be prohibited, outstanding indebtedness under our revolving credit facility and term loan agreements, our senior unsecured notes indentures and their supplements or other loans may be accelerated, and we could be forced to liquidate our assets for less than the values we would receive in a more orderly process.

Our revolving credit facility and term loan agreements and our senior unsecured notes indentures and their supplements contain terms limiting our ability to incur additional debt. These terms, or our failure or inability to meet them, could adversely affect our business and may prevent us from making distributions to our shareholders.

Our revolving credit facility agreement includes various conditions to our borrowing and our revolving credit facility and term loan agreements include various financial and other covenants, including covenants requiring us to maintain certain minimum debt service coverage and leverage ratios, and events of default. Our senior unsecured notes indentures and their supplements also impose customary restrictions on us, including requiring us to comply with certain debt to asset ratios and debt service coverage ratios if we want to incur additional debt and requiring us to maintain at least a specified ratio of total unencumbered assets to debt. We may not be able to satisfy all of these conditions or may default on some of these covenants for various reasons, including matters which are beyond our control. Further, maintaining compliance with these covenants may limit our ability to pursue actions that may otherwise be beneficial to us and our shareholders.

If we are unable to borrow under our revolving credit facility, we may be unable to meet our business obligations or to grow by buying additional properties, or we may be required to sell some of our properties. If we default under our revolving credit facility or term loan agreements, our lenders may demand immediate payment and the lenders under our revolving credit facility may elect not to make further borrowings available to us. Additionally, during the continuance of any event of default under these agreements, we will be limited or in some cases prohibited from making distributions on our common shares. Any default under our revolving credit facility or term loan agreements that resulted in our obligations to repay outstanding indebtedness being accelerated or in our no longer being permitted to borrow under our revolving credit facility would likely have serious and adverse consequences to us and would likely cause the market price of our common shares to materially decline.

In the future, we may obtain additional debt financing, and the covenants and conditions which apply to any such additional indebtedness may be more restrictive than the covenants and conditions contained in our revolving credit facility and term loan agreements and our senior unsecured notes indentures and their supplements. Defaults under our future debt could likely have the same consequences as described above.

RMR LLC and our tenants and senior living managers rely on information technology for their operations, and any material failure, inadequacy, interruption or security failure of that technology could harm our business.

RMR LLC and our tenants and senior living managers rely on information technology networks and systems, including the Internet, to process, transmit and store electronic information and to manage or support a variety of our business processes, including medical records, financial transactions and maintenance of records, which may include personally identifiable information of tenants, residents and vendors, as well as lease data.

49

RMR LLC and our tenants and senior living managers rely on commercially available systems, software, tools and monitoring to provide security for processing, transmitting and storing confidential tenant, customer and vendor information, such as personally identifiable information relating to health and financial accounts. Although RMR LLC and our tenants and senior living managers take various actions to protect the security of the data maintained in their information systems, it is possible that their security measures will not prevent the systems’ improper functioning, or the improper disclosure of personally identifiable information such as in the event of cyber attacks. Security breaches, including physical or electronic break-ins, computer viruses, attacks by hackers and similar breaches, can create system disruptions, shutdowns or unauthorized disclosure of confidential information. Any failure to maintain proper function, security and availability of these information systems could interrupt our or their operations, damage our or their reputation, subject us or them to liability claims or regulatory penalties and could materially and adversely affect us or them.

Insurance on our properties may not adequately cover all losses and uninsured losses could materially and adversely affect us.

Generally, we or our tenants are responsible for the costs of insurance coverage for our properties, such as for casualty, including fire and extended coverage, and liability. Either we purchase the insurance ourselves and, except in the case of our managed senior living communities, our tenants are required to reimburse us, or the tenants buy the insurance directly and are required to list us as an insured party. Under certain circumstances insurance proceeds may not be adequate to restore our economic position with respect to an affected property and we could be materially and adversely affected. Furthermore, we do not have any insurance designated to limit any losses that we may incur as a result of known or unknown environmental conditions which are not caused by an insured event, such as, for example, fire or flood.

Our business could be adversely impacted if there are deficiencies in our disclosure controls and procedures or our internal control over financial reporting.

The design and effectiveness of our disclosure controls and procedures and our internal control over financial reporting may not prevent all errors, misstatements or misrepresentations. While management will continue to review the effectiveness of our disclosure controls and procedures and our internal control over financial reporting, there can be no guarantee that our internal control over financial reporting will be effective in accomplishing all control objectives all of the time. Deficiencies, including any material weaknesses, in our internal control over financial reporting could result in misstatements of our results of operations or our financial statements or could otherwise materially and adversely affect our business, reputation, results of operations, financial condition or liquidity.

Changes in lease accounting standards may materially and adversely affect us.

The Financial Accounting Standards Board, or FASB, is in the process of adopting new accounting rules, to be effective as early as fiscal years ending after December 2018, that will require companies to capitalize all leases on their balance sheets by recognizing a lessee’s rights and obligations. When the final rules are effective, many companies that account for certain leases on an “off balance sheet” basis will be required to account for such leases “on balance sheet.” This change will remove many of the differences in the way companies account for owned property and leased property, and could have a material effect on various aspects of our tenants’ businesses, including their credit quality and the factors they consider in deciding whether to own or lease properties. When the rules are effective, or as the effective date approaches, it could cause companies that lease properties to prefer shorter lease terms, in an effort to reduce the leasing liability required to be recorded on their balance sheets. The new rules could also make lease renewal options less attractive, as, under certain circumstances, the rules will require a tenant to assume that a renewal right will be exercised and accrue a liability relating to the longer lease term.

Risks Related to Our Relationships with RMR Inc., RMR LLC and Five Star

We may not realize the expected benefits of our acquisition of an interest in RMR Inc.

On June 5, 2015,we participated in a transaction with RMR Inc., RMR LLC, ABP Trust and three other REITs to which RMR LLC provides management services in which, among other things, we acquired 5,272,787 shares of RMR Inc.’s Class A common stock, ABP Trust acquired 2,345,000 of our common shares and we amended our management agreements with RMR LLC and extended them for continuing 20 year terms, or the Up-C Transaction.  We subsequently

50

distributed 2,635,379 of the shares of RMR Inc.’s Class A common stock that we received in the Up-C Transaction pro rata to our shareholders.  We believe the Up-C Transaction provided several benefits to us, including an attractive investment in the equity securities of RMR Inc., the further alignment of the interests of RMR LLC, Adam Portnoy and Barry Portnoy with our interests and greater transparency for us and our shareholders into the compensation practices and financial and operating results of RMR LLC.  However, our investment in RMR Inc. is subject to various risks, including the highly competitive nature of RMR LLC’s business and the limited public market for RMR Inc.’s securities, among others, which may result in us losing some or all of our investment in RMR Inc. or otherwise not realizing the benefits we expect from the Up-C Transaction.  For further information on the Up-C Transaction, see Note 5 to our Consolidated Financial Statements included in Part IV, Item 15 of this Annual Report on Form 10-K.

We are dependent upon RMR LLC to manage our business and implement our growth strategy.

We have no employees. Personnel and services that we require are provided to us by RMR LLC pursuant to our management agreements with RMR LLC. Our ability to achieve our business objectives depends on RMR LLC and its ability to manage our properties, identify and complete our acquisitions and dispositions and to execute our growth strategy. Accordingly, our business is dependent upon RMR LLC’s business contacts, its ability to successfully hire, train, supervise and manage its personnel and its ability to maintain its operating systems. If we lose the services provided by RMR LLC or its key personnel, our business and growth prospects may decline. We may be unable to duplicate the quality and depth of management available to us by becoming internally managed or by hiring another manager. Also, in the event RMR LLC is unwilling or unable to continue to provide management services to us, our cost of obtaining substitute services may be greater than the fees we pay RMR LLC under our management agreements, and as a result our expenses may increase.

Each of our executive officers is also an officer of RMR LLC.  Because our executive officers have duties to RMR LLC as well as to our company, we do not have their undivided attention.  They face conflicts in allocating their time and resources between our company and RMR LLC.

Our management structure and agreements and relationship with RMR LLC may restrict our investment activities and may create conflicts of interest or the perception of such conflicts.

RMR LLC is authorized to follow broad operating and investment guidelines and, therefore, has discretion in determining the properties that will be appropriate investments for us, as well as our individual operating and investment decisions. Our Board of Trustees periodically reviews our operating and investment guidelines and our operating activities and investments but it does not review or approve each decision made by RMR LLC on our behalf. In addition, in conducting periodic reviews, our Board of Trustees relies primarily on information provided to it by RMR LLC. Our Managing Trustees control RMR Inc., which is the managing member of and controls RMR LLC.

RMR LLC also acts as the manager for three other NYSE listed REITs: GOV, a publicly traded REIT that owns properties that are majority leased to government tenants, HPT, a publicly traded REIT that owns hotels and travel centers, and SIR, a publicly traded REIT that primarily owns and invests in net leased, single tenant properties. RMR LLC also provides services to other publicly and privately owned companies, including: Five Star, our largest tenant and a manager of our managed senior living communities; TA, which operates and franchises travel centers and convenience stores; and Sonesta, which operates, manages and franchises hotels, resorts and cruise ships. These multiple responsibilities to public companies and other businesses could create competition for the time and efforts of RMR LLC and Messrs. Barry and Adam Portnoy. Also, RMR LLC’s multiple responsibilities to us and to other companies to which it provides management services, including Five Star, may give rise to conflicts of interest or the appearance of such conflicts of interest.

Our management agreements were negotiated between related parties, and the terms, including the fees payable to RMR LLC, may not be as favorable to us as they would have been if they were negotiated between unrelated parties. Our property management fees are calculated based on rents we receive and construction supervision fees for construction at our properties overseen and managed by RMR LLC, and our base business management fee is calculated based upon the lower of the historical costs of our real estate investments and our market capitalization. These fee arrangements could incentivize RMR LLC to pursue acquisitions, capital transactions, tenancies and construction projects or to avoid disposing of our assets in order to increase or maintain its management fees. Our Independent Trustees oversee our acquisition and disposition program and capital transactions and regularly review our property level results of operations, rents, leasing

51

activities, budgets and construction activities as well as market trends. If we do not effectively manage our investment, disposition, and capital transactions and leasing, construction and other property management activities, we may pay increased management fees without proportional benefits to our shareholders.

In our management agreements with RMR LLC, we acknowledge that RMR LLC may engage in other activities or businesses and act as the manager to any other person or entity (including other REITs) even though such person or entity has investment policies and objectives similar to our policies and objectives and we are not entitled to preferential treatment in receiving information, recommendations and other services from RMR LLC. Accordingly, we may lose investment opportunities to, and may compete for tenants with, other businesses managed by RMR LLC.

Barry Portnoy is a Managing Director, officer and controlling shareholder (through ABP Trust) of RMR Inc. and an officer of RMR LLC, and Adam Portnoy is a Managing Director, President, Chief Executive Officer and controlling shareholder (through ABP Trust) of RMR Inc. and an officer of RMR LLC.  Adam Portnoy and Barry Portnoy also own class A membership units of RMR LLC through their ownership of ABP Trust. All of the members of our Board of Trustees, including our Independent Trustees, are members of one or more boards of trustees or directors of other public companies to which RMR LLC provides management services. Our executive officers are also officers of RMR LLC. The foregoing individuals may hold equity in RMR Inc. and other public companies to which RMR LLC provides management services. Any such equity ownership or positions could create, or appear to create, conflicts of interest with respect to matters involving us, the other companies to which RMR LLC provides management services and RMR Inc. and its related parties.

The Up-C Transaction and the agreements entered into as part of the Up-C Transaction are among related persons, which increases the risk of allegations of conflicts of interest, and such allegations may impair our ability to realize the benefits we expect from the Up-C Transaction.

Because of the various relationships among us, GOV, RMR Inc., RMR LLC and the other REITs to which RMR LLC provides management services, the Up-C Transaction and the agreements entered into as part of the Up-C Transaction, including the amendment and extension of our management agreements for continuing 20 year terms, are among related persons. The Up-C Transaction and the terms thereof were negotiated and reviewed by a Joint Special Committee comprised solely of our Independent Trustees and the independent trustees of the other REITs, or the Joint Special Committee, and were separately approved and adopted by an Independent Trustee of ours who did not serve as an independent trustee of any of the other REITs, by a Special Committee of our Board of Trustees, comprised solely of our Independent Trustees, or our Special Committee, and by our Board of Trustees. Morgan Stanley & Co. LLC acted as financial advisor to the Joint Special Committee and Centerview Partners LLC acted as financial advisor to our Special Committee. Nonetheless, the Up-C Transaction may not be on terms as favorable to us or the other REITs to which RMR LLC provides management services as it would have been if it was negotiated among unrelated parties. As a result of these relationships, we may be subject to increased risk that our shareholders or the shareholders of the other REITs to which RMR LLC provides management services may challenge the Up-C Transaction and the agreements entered into as part of the Up-C Transaction. Any such challenge could result in substantial costs and a diversion our management’s attention, could have a material adverse effect on our reputation, business and growth and could adversely affect our ability to realize the benefits we expect from the Up-C Transaction, whether or not the allegations have merit or are substantiated.

The termination of our management agreements may require payment of a substantial termination fee, including in the case of a termination for unsatisfactory performance, which may limit our ability to end our relationship with RMR LLC.

The terms of our management agreements with RMR LLC automatically extend on December 31st of each year so that such terms thereafter end on the 20th anniversary of the date of the extension. We have the right to terminate these agreements: (1) at any time on 60 days’ written notice for convenience, (2) immediately upon written notice for cause, as defined in the agreements, (3) on written notice given within 60 days after the end of any applicable calendar year for a performance reason, as defined in the agreements, and (4) by written notice during the 12 months following a manager change of control, as defined in the agreements. However, if we terminate a management agreement for convenience, or if RMR LLC terminates a management agreement with us for good reason, as defined in such agreement, we are obligated to pay RMR LLC a termination fee in an amount equal to the sum of the present values of the monthly future fees, as

52

defined in the agreement, payable to RMR LLC for the remaining term of the agreement, which term, depending on the time of termination would be between 19 and 20 years. Additionally, if we terminate a management agreement for a performance reason, as defined in the agreement, we are obligated to pay RMR LLC the termination fee calculated as described above, but assuming a remaining term of ten years. These provisions substantially increase the cost to us of terminating the management agreements without cause, which may limit our ability to end our relationship with RMR LLC as our manager. The payment of the termination fee could have a material adverse effect on our financial condition, including our ability to pay dividends to our shareholders.

Our management arrangements with RMR LLC may discourage a  change of control of us.

Our management agreements with RMR LLC have 20 year terms that renew annually. As noted in the preceding risk factor, if we terminate either of these management agreements other than for cause or upon a change of control of our manager, we are obligated to pay RMR LLC a substantial termination fee, see “The termination of our management agreements may require payment of a substantial termination fee, including in the case of a termination for unsatisfactory performance, which may limit our ability to end our relationship with RMR LLC.” For these reasons, our management agreements with RMR LLC may discourage a change of control of us, including a change of control which might result in payment of a premium for our common shares.

We may be at an increased risk for dissident shareholder activities due to perceived conflicts of interest arising from our management structure.

In the past, in particular following periods of volatility in the overall market or declines in the market price of a company’s securities, shareholder litigation, dissident shareholder trustee nominations and dissident shareholder proposals have often been instituted against companies alleging conflicts of interest in business dealings with affiliated and related persons and entities. Our relationships with RMR Inc., Five Star, AIC, the other businesses and entities to which RMR LLC provides management services, Barry Portnoy and Adam Portnoy and other related persons of RMR LLC may precipitate such activities. These activities, if instituted against us, could result in further costs, which could be substantial in amount, and a diversion of our management’s attention even if the action is unfounded.

Our business dealings with Five Star may create conflicts of interest.

Five Star was originally organized as our subsidiary. We distributed substantially all our Five Star ownership to our shareholders on December 31, 2001. One of our Managing Trustees, Mr. Barry Portnoy, serves as a managing director of Five Star. RMR LLC provides management services to both us and Five Star. As of December 31, 2015, our leases with Five Star accounted for 30.8% of our annual rents. As of December 31, 2015, Five Star also managed 60 of our senior living communities. In the future, we expect to do additional business with Five Star. We believe that our current leases, management contracts and other business dealings with Five Star were entered on commercially reasonable terms and that our historical, continuing and increasing business dealings with Five Star have been beneficial to us. Our transactions with Five Star have been approved by our Independent Trustees; however, because of the historical and continuing relationships which we have with Five Star, each of our historical, continuing and expanding business dealings may not be on the same or as favorable terms as we might achieve with a third party with whom we do not have such relationships.

We may experience losses from our business dealings with AIC.

We have invested approximately $6.0 million in AIC, we have purchased a substantial portion of our property insurance in a program designed by AIC, and we periodically consider the possibilities for expanding our relationship with AIC to other types of insurance. We, ABP Trust, Five Star and four other companies to which RMR LLC provides management services each own14.3% of AIC, and we and those other AIC shareholders participate in a combined property insurance program designed and reinsured in part by AIC. Our principal reason for investing in AIC and for purchasing insurance in these programs is to seek to improve our financial results by obtaining improved insurance coverages at lower costs than may be otherwise available to us or by participating in any profits which we may realize as an owner of AIC. While we believe we have in the past benefitted from these arrangements, these beneficial financial results may not occur in the future, and we may need to invest additional capital in order to continue to pursue these results. AIC's business involves the risks typical of an insurance business, including the risk that it may not operate profitably. Accordingly,

53

financial benefits from our business dealings with AIC may not be achieved in the future, and we may experience losses from these dealings.

Risks Related to Our Organization and Structure

Ownership limitations and certain provisions in our declaration of trust, bylaws and contracts, as well as certain provisions of Maryland law, may deter, delay or prevent a change in our control or unsolicited acquisition proposals.

Our declaration of trust prohibits any shareholder other than RMR LLC and its affiliates (as defined under Maryland law), and certain persons who have been exempted by our Board of Trustees, from owning (directly and by attribution) more than 9.8% of the number or value of shares of any class or series of our outstanding shares of beneficial interest, including our common shares. This provision of our declaration of trust is intended to assist with our REIT compliance under the IRC and otherwise to promote our orderly governance. However, this provision also inhibits acquisitions of a significant stake in us and may deter, delay or prevent a change in control of us or unsolicited acquisition proposals that a shareholder may consider favorable. Additionally, provisions contained in our declaration of trust and bylaws or under Maryland law may have a similar impact, including, for example, provisions relating to:

· the authority of our Board of Trustees to make various elections under Maryland’s Unsolicited Takeover Act and other provisions of Maryland law which may delay or otherwise prevent a change of control of us;

· shareholder voting rights and standards for the election of trustees and other provisions which require larger majorities for approval of actions which are not approved by our Trustees than for actions which are approved by our Trustees;

· the authority of our Board of Trustees, and not our shareholders, to adopt, amend or repeal our bylaws and to fill vacancies on our Board of Trustees;

· the fact that only our Board of Trustees or, if there are no trustees, our officers, may call shareholder meetings and that shareholders are not entitled to act without a meeting;

· required qualifications for an individual to serve as a trustee and a requirement that certain of our Trustees be “Managing Trustees” and other Trustees be “Independent Trustees,” as defined in our governing documents;

· limitations on the ability of our shareholders to propose nominees for election as trustees and propose other business to be considered at a meeting of our shareholders;

· limitations on the ability of our shareholders to remove our Trustees; and

· the authority of our Board of Trustees to create and issue new classes or series of shares (includingshares with voting rights and other rights and privileges that may deter a change in control) and issueadditional common shares.

In addition, our shareholders agreement with respect to AIC provides that AIC and the other shareholders of AIC may have rights to acquire our interests in AIC in the event that anyone acquires more than 9.8% of our shares or we experience some other change in control.

54

Our ownership interest in AIC may prevent shareholders from accumulating large share ownership, from nominating or serving as Trustees, or from taking actions to otherwise control our business.

As an owner of AIC, we are licensed and approved as an insurance holding company; and any shareholder who owns or controls 10% or more of our securities or anyone who wishes to solicit proxies for election of, or to serve as, one of our Trustees or for another proposal of business not approved by our Board of Trustees may be required to receive pre-clearance from the concerned insurance regulators. These pre-approval procedures may discourage or prevent investors from purchasing our securities, from nominating persons to serve as our Trustees or from taking other actions.

Our rights and the rights of our shareholders to take action against our Trustees and officers are limited.

Our declaration of trust limits the liability of our Trustees and officers to us and our shareholders for money damages to the maximum extent permitted under Maryland law. Under current Maryland law, our Trustees and officers will not have any liability to us and our shareholders for money damages other than liability resulting from:

· actual receipt of an improper benefit or profit in money, property or services; or

· active and deliberate dishonesty by the Trustee or officer that was established by a final judgment as being material to the cause of action adjudicated.

Our declaration of trust and indemnification agreements require us to indemnify any present or former trustee or officer, to the maximum extent permitted by Maryland law, who is made or threatened to be made a party to a proceeding by reason of his or her service in that capacity. However, except with respect to proceedings to enforce rights to indemnification, we will indemnify any person referenced in the previous sentence in connection with a proceeding initiated by such person against us only if such proceeding is authorized by our declaration of trust or bylaws or by our Board of Trustees or shareholders. In addition, we may be obligated to pay or reimburse the expenses incurred by our present and former Trustees and officers without requiring a preliminary determination of their ultimate entitlement to indemnification. As a result, we and our shareholders may have more limited rights against our present and former Trustees and officers than might otherwise exist absent the provisions in our declaration of trust and indemnification agreements or that might exist with other companies, which could limit your recourse in the event of actions not in your best interest.

Disputes with Five Star or RMR LLC and shareholder litigation against us or our Trustees and officers may be referred to binding arbitration proceedings.

Our contracts with Five Star and RMR LLC provide that any dispute arising under those contracts may be referred to binding arbitration proceedings. Similarly, our bylaws provide that actions by our shareholders against us or against our Trustees and officers, including derivative and class actions, may be referred to binding arbitration proceedings. As a result, we and our shareholders would not be able to pursue litigation for these disputes in courts against Five Star, RMR LLC or our Trustees and officers if the disputes were referred to arbitration. In addition, the ability to collect attorneys' fees or other damages may be limited in the arbitration proceedings, which may discourage attorneys from agreeing to represent parties wishing to commence such a proceeding.

We may change our operational, financing and investment policies without shareholder approval and we may become more highly leveraged, which may increase our risk of default under our debt obligations.

Our Board of Trustees determines our operational, financing and investment policies and may amend or revise our policies, including our policies with respect to our intention to qualify for taxation as a REIT, acquisitions, dispositions, growth, operations, indebtedness, capitalization and distributions, or approve transactions that deviate from these policies, without a vote of, or notice to, our shareholders. Policy changes could adversely affect the market value of our common shares and our ability to make distributions to our shareholders. Further, our organizational documents do not limit the amount or percentage of indebtedness, funded or otherwise, that we may incur. Our Board of Trustees may alter or eliminate our current policy on borrowing at any time without shareholder approval. If this policy changed, we could become more highly leveraged, which could result in an increase in our debt service costs. Higher leverage also increases the risk of default on our obligations. In addition, a change in our investment policies, including the manner in which we

55

allocate our resources across our portfolio or the types of assets in which we seek to invest, may increase our exposure to interest rate risk, real estate market fluctuations and liquidity risk.

Our bylaws designate the Circuit Court for Baltimore City, Maryland or, if that court does not have jurisdiction, the United States District Court for the District of Maryland, Baltimore Division, as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our shareholders, which could limit our shareholders’ ability to obtain a favorable judicial forum for disputes with us or our Trustees, officers, manager, agents or employees.

Our bylaws currently provide that, unless we consent in writing to the selection of an alternative forum or the dispute has been referred to binding arbitration, the Circuit Court for Baltimore City, Maryland, or if that court does not have jurisdiction, the United States District Court for the District of Maryland, Baltimore Division, will be the sole and exclusive forum for: (1) any derivative action or proceeding brought on our behalf; (2) any action asserting a claim for breach of a duty owed by any Trustee, officer, manager, agent or employee of ours to us or our shareholders; (3) any action asserting a claim against us or any Trustee, officer, manager, agent or employee of ours arising pursuant to the Maryland General Corporation Law, our declaration of trust or bylaws brought by or on behalf of a shareholder; or (4) any action asserting a claim against us or any Trustee, officer, manager, agent or employee of ours that is governed by the internal affairs doctrine.  This choice of forum provision may limit a shareholder’s ability to bring a claim in a judicial forum that the shareholder believes is favorable for disputes with us or our Trustees, officers, manager, agents or employees, which may discourage lawsuits against us and our Trustees, officers, manager or agents.  Any person or entity purchasing or otherwise acquiring or holding any interest in our shares of beneficial interest shall be deemed to have notice of and to have consented to this provision of our bylaws, as they may be amended from time to time.  This choice of forum provision of our bylaws does not abrogate or supersede other provisions of our bylaws stipulating that actions by our shareholders against us or against our Trustees and officers, including derivative and class actions, may be referred to binding arbitration proceedings.

Risks Related to Our Taxation

The loss of our status as a REIT for U.S. federal income tax purposes could have significant adverse consequences. 

As a REIT, we generally do not pay federal and state income taxes. However, actual qualification for taxation as a REIT under the IRC depends on satisfying complex statutory requirements, for which there are only limited judicial and administrative interpretations. We believe that we have been organized and have operated, and will continue to be organized and to operate, in a manner that qualified and will continue to qualify us to be taxed under the IRC as a REIT. However, we cannot be certain that, upon review or audit, the IRS will agree with this conclusion. Furthermore, there is no guarantee that the federal government will not someday eliminate REITs or adversely modify their taxation under the IRC. 

Maintaining our qualification for taxation as a REIT will require us to continue to satisfy tests concerning, among other things, the nature of our assets, the sources of our income and the amounts we distribute to our shareholders. In order to meet these requirements, it may be necessary for us to sell or forgo attractive investments. 

If we cease to maintain our qualification for taxation as a REIT, then our ability to raise capital might be adversely affected, we will be in breach under our revolving credit facility and term loan agreements, we may be subject to material amounts of federal and state income taxes and the value of our shares likely would decline. In addition, if we lose or revoke our qualification as a REIT for a taxable year, we will generally be prevented from requalifying as a REIT for the next four taxable years.

Distributions to shareholders generally will not qualify for reduced tax rates.

Dividends payable by U.S. corporations to noncorporate shareholders, such as individuals, trusts and estates, are generally eligible for reduced tax rates. Distributions paid by REITs, however, generally are not eligible for these reduced rates. The more favorable rates for corporate dividends may cause investors to perceive that an investment in a REIT is

56

less attractive than an investment in a non-REIT entity that pays dividends, thereby reducing the demand and market price of our shares.

REIT distribution requirements could adversely affect our ability to execute our business plan.

We generally must distribute annually at least 90% of our taxable income, subject to specified adjustments and excluding any net capital gain, in order for federal corporate income tax not to apply to earnings that we distribute. To the extent that we satisfy this distribution requirement, but distribute less than 100% of our taxable income, we will be subject to federal corporate income tax on our undistributed taxable income. We intend to make distributions to our shareholders to comply with the REIT requirements of the IRC. In addition, we will be subject to a 4% nondeductible excise tax if the actual amount that we pay out to our shareholders in a calendar year is less than a minimum amount specified under federal tax laws.

From time to time, we may generate taxable income greater than our income for financial reporting purposes prepared in accordance with U.S. generally accepted accounting principles, or GAAP, or differences in timing between the recognition of taxable income and the actual receipt of cash may occur. If we do not have other funds available in these situations we could be required to borrow funds on unfavorable terms, sell investments at disadvantageous prices or distribute amounts that would otherwise be invested in future acquisitions to make distributions sufficient to enable us to pay out enough of our taxable income to satisfy the REIT distribution requirement and to avoid corporate income tax and the 4% excise tax in a particular year. These alternatives could increase our costs or reduce our shareholders’ equity. Thus, compliance with the REIT requirements may hinder our ability to grow, which could adversely affect the value of our shares.

Even if we qualify and remain qualified for taxation as a REIT, we may face other tax liabilities that reduce our cash flow.

Even if we qualify and remain qualified for taxation as a REIT, we may be subject to federal, state and local taxes on our income and assets, including taxes on any undistributed income, excise taxes, state or local income, property and transfer taxes, such as mortgage recording taxes, and other taxes. See “Business—United States Federal Income Tax Considerations—Taxation as a REIT.” For example, some state jurisdictions may in the future limit or eliminate certain favorable deductions, including the dividends paid deduction, which could increase our income tax expense. In addition, in order to meet the requirements for qualification and taxation as a REIT, prevent the recognition of particular types of non-cash income, or avert the imposition of a 100% tax that applies to specified gains derived by a REIT from dealer property or inventory, we may hold some of our assets and operations through our TRSs or other subsidiary corporations that will be subject to corporate level income tax at regular rates. Any of these taxes would decrease cash available for distribution to our shareholders.

If arrangements involving our TRSs fail to comply as intended with the REIT qualification and taxation rules, we may fail to qualify for taxation as a REIT or be subject to significant penalty taxes.

We lease many of our properties to our TRSs pursuant to arrangements that, under the IRC, are intended to qualify the rents we receive from our TRSs as income that satisfies the REIT gross income tests. We also intend that our transactions with our TRSs be conducted on arm’s length bases so that we and our TRSs will not be subject to penalty taxes under the IRC applicable to mispriced transactions. While relief provisions can sometimes excuse REIT gross income testfailures, significant penalty taxes can still be imposed.

For our TRS arrangements to comply as intended with the REIT qualification and taxation rules under the IRC, a number of requirements must be satisfied, including:

· our TRSs may not directly or indirectly operate or manage a health care facility, as defined by the IRC;

· the leases to our TRSs must be respected as true leases for federal income tax purposes and not as service contracts, partnerships, joint ventures, financings, or other types of arrangements;

57

· the leased properties must constitute qualified health care properties (including necessary or incidental property) under the IRC;

· the leased properties must be managed and operated on behalf of the TRSs by independent contractors who are less than 35% affiliated with us and who are actively engaged (or have affiliates so engaged) in the trade or business of managing and operating qualified health care properties for persons unrelated to us; and

· the rental and other terms of the leases must be arm’s length.

There can be no assurance that the IRS or a court will agree with our assessment that our TRS arrangements comply as intended with applicable REIT qualification and taxation rules. If arrangements involving our TRSs fail to comply as intended, we may fail to qualify for taxation as a REIT or be subject to significant penalty taxes.

Risks Related to Our Securities

We cannot assure that we will continue to make distributions to our shareholders, and distributions we make may include a return of capital.

We intend to continue to make regular quarterly distributions to our shareholders. However:

· our ability to make distributions will be adversely affected if any of the risks described herein, or other significant events, occur;

· our making of distributions is subject to compliance with restrictions contained in our revolving credit facility and term loan agreements and may be subject to restrictions in future debt we may incur; and

· any distributions will be made in the discretion of our Board of Trustees and will depend upon various factors that our Board of Trustees deems relevant, including our results of operations, our financial condition, debt and equity capital available to us, our expectation of our future capital requirements and operating performance, including our funds from operations, or FFO, our normalized funds from operations, or Normalized FFO, restrictive covenants in our financial or other contractual arrangements (including those in our revolving credit facility and term loan agreements), tax law requirements to maintain our qualification for taxation as a REIT, restrictions under Maryland law and our expected needs and availability of cash to pay our obligations.

For these reasons, among others, our distribution rate may decline or we may cease making distributions. Also, our distributions may include a return of capital.

Changes in market conditions could adversely affect the market price of our common shares.

As with other publicly traded equity securities and REIT securities, the value of our common shares depends on various market conditions that may change from time to time, including:

· the extent of investor interest in our securities;

· the general reputation of REITs and externally managed companies and the attractiveness of our equity securities in comparison to other equity securities, including securities issued by other real estate based companies or by other issuers less sensitive to rises in interest rates;

· our underlying asset value;

· investor confidence in the stock and bond markets, generally;

58

· national economic conditions;

· market interest rates;

· changes in tax laws;

· changes in our credit ratings; and

· general market conditions.

We believe that one of the factors that investors consider important in deciding whether to buy or sell equity securities of a REIT is the distribution rate, considered as a percentage of the price of the equity securities, relative to market interest rates. Interest rates have been at historically low levels for an extended period of time.  There is a general market perception that REIT shares outperform in low interest rate environments and underperform in rising interest rate environments when compared to the broader market.  During 2015, there were periods when there were market expectations of rising interest rates, which temporarily increased market interest rates and resulted in declines in the value of REIT shares generally that exceeded any declines for the general market.  In December 2015, the U.S. Federal Reserve raised its benchmark interest rate by a quarter of a percentage point.  Market  interest rates may continue to increase in the near to intermediate term.  If market interest rates continue to increase, or if there is market expectation of such increases, prospective purchasers of REIT equity securities may want to achieve a higher distribution rate. Thus, higher market interest rates, or the expectation of higher interest rates, could cause the market price of our common shares to decline.

Further issuances of equity securities may be dilutive to current shareholders.

The interests of our existing shareholders could be diluted if we issue additional equity securities to finance future acquisitions or to repay indebtedness. Our ability to execute our business strategy depends on our access to an appropriate blend of debt financing, which may include secured and unsecured debt, and equity financing, which may include common and preferred shares.

The Notes are structurally subordinated to the payment of all indebtedness and other liabilities and any preferred equity of our subsidiaries.

We are the sole obligor on our outstanding senior unsecured notes, and our outstanding senior unsecured notes and any notes or other debt securities we may issue in the future, or (together with our outstanding senior unsecured notes) the Notes, are not, and any Notes we may issue in the future may not be, guaranteed by any of our subsidiaries. Our subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due on the Notes, or to make any funds available therefor, whether by dividend, distribution, loan or other payments. The rights of holders of Notes to benefit from any of the assets of our subsidiaries are subject to the prior satisfaction of claims of our subsidiaries’ creditors and any preferred equity holders. As a result, the Notes are, and, except to the extent that future Notes are guaranteed by our subsidiaries, will be, structurally subordinated to all of the debt and other liabilities and obligations of our subsidiaries, including guarantees of other indebtedness of ours, payment obligations under lease agreements, trade payables and preferred equity. As of December 31, 2015, our subsidiaries had total indebtedness and other liabilities (excluding security and other deposits and guaranties) of $774.3 million and our subsidiaries did not have any outstanding preferred equity.

The Notes are unsecured and effectively subordinated to all of our existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness.

Our outstanding Notes are not secured and any Notes we may issue in the future may not be secured. Upon any distribution to our creditors in a bankruptcy, liquidation, reorganization or similar proceeding relating to us or our property, the holders of our secured debt will be entitled to exercise the remedies available to a secured lender under applicable law and pursuant to the instruments governing such debt and to be paid in full from the assets securing that secured debt before any payment may be made with respect to Notes that are not secured by those assets. In that event, because such Notes will not be secured by any of our assets, it is possible that there will be no assets from which claims of holders of such

59

Notes can be satisfied or, if any assets remain, that the remaining assets will be insufficient to satisfy those claims in full. If the value of such remaining assets is less than the aggregate outstanding principal amount of such Notes and accrued interest and all future debt ranking equally with such Notes, we will be unable to fully satisfy our obligations under such Notes. In addition, if we fail to meet our payment or other obligations under our secured debt, the holders of that secured debt would be entitled to foreclose on our assets securing that secured debt and liquidate those assets. Accordingly, we may not have sufficient funds to pay amounts due on such Notes. As a result, holders of Notes may lose a portion of or the entire value of their investment in such Notes. Further, the terms of the outstanding Notes permit, and the terms of any Notes we may issue in the future may permit us to incur additional secured indebtedness subject to compliance with certain debt ratios. The Notes that are not secured will be effectively subordinated to any such additional secured indebtedness. As of December 31, 2015, we had $667.5 million in secured mortgage debts.

There may be no public market for the Notes, and one may not develop, be maintained or be liquid.

Except in certain cases, we have not applied for listing of the outstanding Notes on any securities exchange or for quotation of the outstanding Notes on any automatic dealer quotation system and may not do so for Notes issued in the future. We can give no assurances concerning the liquidity of any market that may develop for these Notes, the ability of any investor to sell these Notes or the price at which investors would be able to sell them.  Except in certain cases, if a market for the Notesdoes not develop, investors may be unable to resell these Notes for an extended period of time, if at all. If a market for these Notes does develop, it may not continue or it may not be sufficiently liquid to allow holders to resell them. Consequently, investors may not be able to liquidate their investment readily, and lenders may not readily accept the Notes as collateral for loans.

The Notes may trade at a discount from their initial issue price or principal amount, depending upon many factors, including prevailing interest rates, the ratings assigned by rating agencies, the market for similar securities and other factors, including general economic conditions and our financial condition, performance and prospects. Any decline in trading prices, regardless of cause, may adversely affect the liquidity and trading markets for the Notes.

A downgrade in credit ratings could materially adversely affect the market value of the Notes and may increase our cost of capital.

The outstanding Notes are rated by two rating agencies and any Notes we may issue in the future may be rated by one or more rating agencies. These credit ratings are continually reviewed by rating agencies and may change at any time based upon, among other things, our results of operations and financial condition. Negative changes in the ratings assigned to our debt securities could have an adverse effect on the market prices of the Notes and our costs and availability of capital, which could in turn have a material adverse effect on our results of operations and our ability to satisfy our debt service obligations.

Redemption may adversely affect noteholders’ return on the Notes.

We have the right to redeem some or all of the outstanding Notes prior to maturity and may have such a right with respect to any Notes we issue in the future. We may redeem such Notes at times when prevailing interest rates may be relatively low compared to the interest rate of such Notes. Accordingly, holders of such Notes may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as that of the Notes.

All common share distributions shown in the table above have been paid, except for the quarterly distribution for the fourth quarter of 2015, which we expect to pay to shareholders on or about February 23, 2016. We currently intend to continue to declare and pay common share distributions on a quarterly basis in cash. However, the timing, amount  and form of future distributions is determined at the discretion of our Board of Trustees and will depend upon various factors that our Board of Trustees deems relevant, including our results of operations, our financial condition, debt and equity capital available to us, our expectations of our future capital requirements and operating performance, including our FFO, our Normalized FFO, restrictive covenants in our financial or other contractual arrangements (including those in our revolving credit facility and term loan agreements), tax law requirements to maintain our qualification for taxation as a REIT, restrictions under Maryland law and our expected needs and availability of cash to pay our obligations. Therefore, there can be no assurance that we will continue to pay distributions in the future or that the amount of distributions we do pay will not decrease.

In addition to the cash distributions paid to our common shareholders in 2015, on December 14, 2015, we distributed 2,635,379 shares, or 0.0111 of a share for each of our common shares, of RMR Inc. shares of class A common stock we owned to our common shareholders as a special distribution.  This distribution resulted in a taxable valuation of this in-kind distribution of $0.1320 for each of our common shares.

Managed Senior Living Communities.

Five Star manages 60 of our senior living communities with 8,190 living units for our account under long term agreements. Trinity Lifestyles Management LLC, or Trinity, manages five of our senior living communities with 395 living units for our account. These 65 communities had an undepreciated carrying value of $1.4 billion and a net book value of $1.2 billion at December 31, 2015. The revenues at these managed senior living communities are primarily derived from services to residents and we record revenues when services are provided.

As noted below, certain of our management agreements are combined under pooling agreements, which combine the determination of fees and expenses of the communities that are subject to the applicable pooling agreement. With the exception of the management agreement for a senior living community in New York, the management agreements for the communities Five Star manages for our account provide Five Star with a management fee equal to 3% of the gross revenues realized at the communities, plus reimbursement for Five Star’s direct costs and expenses related to the communities and an incentive fee equal to 35% of the annual net operating income of the communities after we realize an annual return equal to 8% of our invested capital. The management agreements generally expire between December 31, 2030 and December 31, 2035, and are subject to automatic renewal for two consecutive 15 year terms, unless earlier terminated or timely notice of nonrenewal is delivered. The management agreements generally provide that we and Five Star each have the option to terminate the contracts upon the acquisition by a person or group of more than 9.8% of the other’s voting stock and upon other change in control events affecting the other party, as defined in those documents, including the adoption of any shareholder proposal (other than a precatory proposal) or the election to the board of directors or board of trustees of any individual if such proposal or individual was not approved, nominated or appointed, as the case may be, by vote of a majority of the board of directors or board of trustees in office immediately prior to the making of such proposal or the nomination or appointment of such individual.

In connection with the management agreements, we and Five Star have entered into four combination agreements, or pooling agreements: three pooling agreements combine our management agreements for communities that include assisted living units, or the AL Pooling Agreements, and a fourth pooling agreement combines our management agreements for communities consisting only of independent living units, or the IL Pooling Agreement. We entered into the initial AL Pooling Agreement in May 2011, the second AL Pooling Agreement in October 2012 and the third AL Pooling Agreement in November 2013. Our first AL Pooling Agreement includes 20 identified communities, our second AL Pooling Agreement includes 19 identified communities, and our third AL Pooling Agreement includes the management agreements for three communities. We entered into the IL Pooling Agreement in August 2012 and that agreement currently includes management agreements for two communities that have only independent living units. Each of the AL Pooling Agreements and the IL Pooling Agreement combines the determination of fees and expenses of the various communities that are subject to such pooling agreement, including determinations of our return of our invested capital and Five Star’s incentive fees. In May 2015, we acquired 38 senior living communities, 19 of which were managed communities and were acquired using TRS structures. We terminated the pre-existing management agreements for 14 of these senior living communities and entered into management agreements with Five Star to manage these 14 communities. Our senior living community in New York, a senior living community of ours in California and the 14 senior living communities we acquired in May 2015, all of which are managed by Five Star, are not included in a pooling agreement. For further information, see Note 3 and Note 5 to our Consolidated Financial Statements included in Part IV, Item 15 of this Annual Report on Form 10-K). The remaining five communities we acquired in May 2015 are managed by Trinity.  Pursuant to our management agreements with Trinity, we receive a return each month based on excess cash flows derived from each of the communities. The management agreements for these communities provide Trinity with a base management fee equal to 5% of the gross revenues realized at the communities, plus reimbursement for Trinity’s direct costs and expenses related to the communities and an incentive fee equal to specified operating thresholds.

During the year ended December 31, 2015, we entered into MOB lease renewals for 762,887 square feet and new MOB leases for 269,586 square feet, at weighted average rental rates that were 2.3% above rents previously charged for the same space. Weighted average lease terms for leases entered into during 2015were 8.5years. Commitments for tenant improvement, leasing commission costs and concessions for leases we entered into during 2015 totaled $25.6 million, or $24.79 per square foot on average (approximately $2.92 per square foot per year of the lease term).

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 senior living communities segment as we believe that a comparison of the results for our comparable properties for our triple net senior living communities segment is generally consistent from period to period and a separate, comparable properties comparison is not meaningful.

Rental income.Rental income increased primarily because of rents from 20 leased senior living communities we acquired in May and September 2015. These acquisitions represent $23,756, or 93.8%, of the net increase in rental income. Rental income also increased due to increased rents resulting from our purchase of approximately $47,248 of improvements to our properties that are leased by Five Star since January 1, 2014. These increases in rental income were partially offset by the sale of 10 senior living communities since January 1, 2014. Rental income increased year over year on a comparable property basis by $3,074, primarily as a result of our improvement purchases at certain of the 211 communities we have owned continuously since January 1, 2014 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. The reconciliation of NOI to net income for our triple net senior living communities segment 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 recognized in this segment increased primarily as a result of the acquisitions and capital improvement purchases described above.

Impairment of assets.  During 2015, we recorded impairment of assets charges of $194 related to the sales of senior living communities in 2015. During 2014, we recorded an impairment adjustment of $610 related to the sale of one senior living community in October 2014, and also recorded an impairment of assets charge of $600 to reduce the carrying value of one of our senior living communities classified as held for sale as of December 31, 2014 to its estimated net sale price.

Interest expense.  Interest expense for our triple net leased senior living communities arises from mortgage debts and capital leases secured by 31 of these properties.  The decrease in interest expense is the result of loan repayments since January 1, 2014 and the regularly scheduled amortization of our mortgage debts. In October 2014, we prepaid a $14,700 loan associated with certain revenue bonds that had an annual interest rate of 5.88% and since January 1, 2014, we have prepaid or repaid mortgage debts of $25,768 with a weighted average annual interest rate of 5.99%. The decrease in interest expense is partially offset by mortgage debts of $56,691 encumbering four properties with a weighted average annual interest rate of 5.33% which we assumed in connection with the May and September 2015 acquisition of 20 triple net leased senior living communities described above.

(Loss) gain on early extinguishment of debt.  Loss on early extinguishment of debt recognized in 2015 is a result of the prepayment of three mortgages in the second quarter of 2015. Gain on early extinguishment of debt recognized in 2014 is a result of an October 2014 mortgage prepayment.

76

Gain on sale of properties.  Gain on sale of properties is a result of the sale of one senior living community in January 2014, two senior living communities in June 2014 and three senior living communities in October 2014.

(1) Consists of managed senior living communities we have owned continuously since January 1, 2014.

(2) The change in total properties and number of units / beds for All Properties reflects the May 2015 acquisitions of 19managed senior living communities. We also acquired an additional managed senior living community in May 2015 located adjacent to a community that we own which is managed by Five Star. This community and the community we previously owned are now operated as a single integrated community under one management agreement.

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 results from residents fees and services from the managed senior living communities we acquired in May 2015. We also acquired two managed senior living communities in December 2014. These acquisitions represent $45,594, or 91.8%, of the net increase in residents fees and services. The remainder of the change is caused by the increase in rates charged offset by a decrease in occupancy.

Property operating expenses.Property operating expenses include expenses incurred at our managed senior living communities and consist of real estate taxes, utility expense, insurance, salaries and benefits of property level personnel, repairs and maintenance expense, cleaning expense, management fees and other direct costs of operating these properties. The acquisitions described above represent $31,956, or 96.3%, of the net increase in property operating expenses.

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”.

77

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 acquisitions described above.

Interest expense.Interest expense for our managed senior living communities arises from mortgage debts secured by 19 of these properties. Interest expense decreased as a result of the prepayment or repayment of eight mortgages since January 1, 2014 with an aggregate principal balance of $93,070 and a weighted average annual interest rate of 5.93%, as well as regularly scheduled amortization of our mortgage debts. The decrease in interest expense is partially offset by assumed mortgage debts of $94,786 encumbering 13 properties with a weighted average annual interest rate of 4.12% in connection with the May 2015 acquisition of 19 managed senior living communities described above.

Loss on early extinguishment of debt. Loss on early extinguishment of debt recognized in 2015 is a result of the prepayment of four mortgages in the second quarter of 2015 and the write off of certain unamortized origination costs.  Loss on early extinguishment of debt recognized in 2014 is a result of a December 2014 mortgage prepayment and the write off of certain unamortized origination costs.

Net income	$	38,360	$	29,805	$	8,555	28.7	%

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 increase in the average monthly rate of 2.0% at the 44 communities we have owned continuously since January 1, 2014, partially offset by a decline in occupancy of 80 basis points.

Property operating expenses.  Property operating expenses consist of real estate taxes, utility expense, insurance, salaries and benefit costs of property level personnel, repairs and maintenance expense, cleaning expense, management fees and other direct costs of operating these properties.  Property operating expenses decreased at the 44 communities we have owned continuously since January 1, 2014, primarily due to decreases in repairs and maintenance expense.

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, 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. The increase in depreciation expense is primarily attributable to capital expenditures to improve these properties, partially offset by a decrease in the amount of amortization of in place resident agreements as some of these assets became fully amortized.

Interest expense. Interest expense for our managed senior living communities arises from mortgage debts secured by six of these properties.  Interest expense decreased as a result of the prepayment or repayment of eight mortgages since January 1, 2014 that had an aggregate principal balance of $93,070 and a weighted average annual interest rate of 5.93%, as well as regularly scheduled amortization of these mortgage debts.

78

Loss on early extinguishment of debt. Loss on early extinguishment of debt recognized in 2015 is a result of the prepayment of four mortgages in the second quarter of 2015and the write off of certain unamortized origination costs.  Loss on early extinguishment of debt recognized in 2014 is a result of a December 2014 mortgage prepayment and the write off of certain unamortized origination costs.

Net income	$	126,859	$	102,399	$	24,460	23.9	%

Rental income. Rental income increased primarily because of rents from 25 MOBs (26 buildings) we acquired for approximately $1,694,207 since January 1, 2014.  These acquisitions represent $79,577, or 101.3%, of the net increase in rental income, which was partially offset by a decrease in rental income from comparable properties. Rental income includes non-cash straight line rent adjustments totaling $13,438 and $8,788 and net amortization of approximately $3,840 and $2,101 of acquired above and below market lease adjustments for the years ended December 31, 2015 and 2014, respectively.

79

Property operating expenses.  Property operating expenses consist of real estate taxes, utility expense, salaries and benefit costs of property level personnel, repairs and maintenance expense, cleaning expense, property management fees and other direct costs of operating these properties.  The acquisitions described above represent $15,848, or 79.8%, of the net increase in property operating expenses. The remainder of the change is primarily attributable to increased real estate taxes.

Net operating income.  NOI increased because of the changes in rental income and property operating expenses described above. The reconciliation of NOI to net income for our MOB segment 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 increased primarily because of our MOB acquisitions since January 1, 2014 as well as capital expenditures to improve our MOBs of $49,409 since January 1, 2014.

Interest expense.  Interest expense for our MOBs arises from mortgage debts secured by 9 properties (10 buildings).  The increase in interest expense is the result of our assumption of $45,585 of mortgage debts in connection with our acquisition of three MOBs (three buildings) since January 1, 2014 with a weighted average annual interest rate of 5.26%, offset by the prepayment of two mortgages during the fourth quarter of 2015 that had a total principal balance of $52,000 and a weighted average annual interest rate of 5.64%, as well as the regularly scheduled amortization of our mortgage debts.

(Loss) income from discontinued operations. Loss from discontinued operations for the year ended December 31, 2015 resulted from a loss on one MOB (four buildings) sold in April 2015 and the reduction in rental income after the sale of three MOBs (three buildings) during the second and third quarters of 2014.

Impairment of assets from discontinued operations.  During the year ended December 31, 2015, we recorded impairment of assets charges to reduce the carrying value of one of our MOBs (four buildings) to its estimated fair value less costs to sell. During the year ended December 31, 2014, we recorded asset impairment adjustments of $333 to increase the carrying value of the three MOBs (three buildings) we sold in 2014 to their sales price.  We also recorded impairment of assets charges of $4,710 to reduce the carrying value of our one MOBs (four buildings) then classified as discontinued operations to its estimated net sales price.

Rental income.  Rental income decreased as a result of a decrease in rents and occupancy at certain comparable properties since January 1, 2014, including lower net non‑cash items affecting rental income. Rental income includes non‑cash straight line rent adjustments totaling $4,308 and $4,550 and net amortization of approximately $(3,728) and $(3,162) of acquired above and below market lease adjustments for the years ended December 31, 2015 and 2014, respectively.

Property operating expenses.  Property operating expenses consist of real estate taxes, utility expense, salaries and benefit costs of property level personnel, repairs and maintenance expense, cleaning expense, property management fees and other direct costs of operating these properties. Property operating costs increased principally because of increases

80

in real estate tax expense and increased repairs and maintenance expenses at certain of these properties. These increased expenses were partially offset by a decrease in utility expenses at various properties for the year ended December 31, 2015 compared to the year ended December 31, 2014.

Net operating income.  NOI decreased because of the 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 consolidated reconciliation of NOI to net income are included below in “Non‑GAAP Financial Measures”.

Depreciation expense.  Depreciation expense increased due to an increase in the amortization of leasing costs and depreciation expense on fixed assets, partially offset by a reduction in amortization of acquired in place real estate leases that we amortize over the respective lease terms due to certain of those assets having been fully amortized.

Interest expense.  Interest expense for our MOBs arises from mortgage debts secured by certain of these properties. The decrease in interest expense is the result of the prepayment of two mortgages during the fourth quarter of 2015 that had a total principal balance of $52,000 and a weighted average annual interest rate of 5.64% as well as the regularly scheduled amortization of our mortgage debts.

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

Rental income. Rental income increased due to scheduled rent increases at certain of our wellness centers where increases are based on the consumer price index. Rental income includes non-cash straight line rent adjustments totaling approximately $550 in each of the years ended December 31, 2015 and 2014. Rental income also includes net amortization of approximately $221 of acquired real estate leases and obligations in each of the years ended December 31, 2015 and 2014, respectively.

Depreciation expense.Depreciation expense remained consistent as we did not make any wellness center acquisitions or other capital investments in this segmentfor the years ended December 31, 2015 and 2014.

81

General and administrative expense.General and administrative expenses consist of fees and expenses of our trustees, fees paid to RMR LLC 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 January 1, 2014, partially offset by lower business management fees payable to RMR LLC due to the fees being based on an average market capitalization calculation rather than average historical cost of assets for part of 2015, the amortization of the liability we recorded in connection with our June 2015 acquisition of RMR Inc. shares as described below,  and a decrease in equity compensation expense as a result of a decrease in our share price in 2015 as compared to 2014. For further discussion of the liability recorded in connection with the June 2015 acquisition of RMR Inc. shares, see Note 5to our Consolidated Financial Statements included in Part IV, Item 15 of this Annual Report on Form 10‑K.

Acquisition related costs.  Acquisition related costs represent legal and due diligence costs incurred in connection with our acquisition activity during the years ended December 31, 2015 and 2014. Acquisition related costs increased during the year ended December 31, 2015 due to an increase in the number of properties acquired during that period compared to the year ended December 31, 2014.

Dividend income.Dividend income recognized in 2015 is a result of a cash dividend received in 2015 from our investment in RMR Inc. shares related to the period from June 5, 2015 to December 14, 2015. Dividend income recognized in 2014 is a result of dividends received in 2014 from our investment in Equity Commonwealth, or EQC (f/k/a CommonWealth REIT). We sold all of our EQC shares in 2015.

Interest and other income.  Interest and other income remained flat for the years ended December 31, 2015 and 2014 and is generally a result of our investable cash on hand.

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, our May 2014 term loan borrowing of $350,000 at an annual interest rate of LIBOR plus 140 basis points, our September 2015 term loan borrowing of $200,000 at an annual interest rate of LIBOR plus 180 basis points and increased borrowings under our revolving credit facility. These increases were partially offset by our November 2015 prepayment of our $250,000 of 4.30% senior unsecured notes.

Loss on distribution to common shareholders of The RMR Group Inc. common stock.  We recorded a $38,437 loss on the distribution of RMR Inc. shares we distributed to our shareholders in December 2015, which represents the difference between our carrying value and the fair value of the RMR Inc. shares on the distribution date.

Loss on early extinguishment of debt.In December 2014, we entered an agreement to acquire 38 senior living communities. Simultaneous with entering this agreement, we obtained a bridge loan commitment for $700,000. In February 2015, we terminated the bridge loan commitment and recognized a loss of $1,409 on early extinguishment of debt in the first quarter of 2015. In September 2015, we amended our revolving credit facility agreement, which resulted in a loss on early extinguishment of debt of $21 related to the write off of certain capitalized but unamortized costs of the prior revolving credit facility agreement. In November 2015, we prepaid our $250,000 of 4.30% senior unsecured notes due January 2016, which resulted in a loss on early extinguishment of debt of $175 related to the write off of certain unamortized origination costs of the notes.

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 senior living communities segment as we believe that a comparison of the results for our comparable properties for our triple net senior living communities segment is generally consistent from period to period and a separate, comparable properties comparison is not meaningful.

Rental income.  Rental income decreased year over year primarily due to our sale of two rehabilitation hospitals during the fourth quarter of 2013, a senior living community in the third quarter of 2013, a senior living community in the first quarter of 2014, two senior living communities in the second quarter of 2014, and three senior living communities in the fourth quarter of 2014.  This decrease was partially offset by increased rents resulting from our purchase of approximately $53,012 of improvements to our properties that are leased by Five Star since January 1, 2013, pursuant to the terms of the leases. Rental income increased year over year on a comparable property basis by $5,595 primarily as a

83

result of our improvement purchases at certain of the 214 communities that we owned continuously from January 1, 2013 through December 31, 2014, and the resulting increased rent, pursuant to the terms of those leases.

Net operating income.  NOI decreased because of the changes in rental income described above. The reconciliation of NOI to net income for our triple net senior living communities segment 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 recognized in this segment decreased year over year as a result of the sale of two rehabilitation hospitals during the fourth quarter of 2013, a senior living community in the third quarter of 2013, a senior living community in the first quarter of 2014, two senior living communities in the second quarter of 2014, and three senior living communities in the fourth quarter of 2014. This decrease was partially offset by our purchase of improvements to our properties that are leased by Five Star since January 1, 2013.

Impairment of assets.  During 2014, we recorded an impairment adjustment of $610 related to the sale of one senior living community in October 2014, and also recorded an impairment of assets charge of $600 to reduce the carrying value of one of our senior living communities classified as held for sale as of December 31, 2014 to its estimated net sale price. During 2013, we recorded impairment of assets charges of $6,685 to reduce the carrying value of five of our senior living communities classified as held for sale as of December 31, 2013 to their estimated sales price.

Interest expense.  Interest expense for our triple net senior living communities arises from mortgage debts secured by certain of these properties. The decrease in interest expense is the result of the June 2013 prepayment of four mortgages that had an aggregate principal balance of $10,377 and a weighted average annual interest rate of 6.1%, 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 with a principal balance of $11,926 and an interest rate of 6.25%, as well as the regularly scheduled amortization of our mortgage debts.

Gain on early extinguishment of debt.  Gain on early extinguishment of debt is a result of the October 2014 mortgage prepayment described in interest expense changes above.

Gain on sale of properties.  Gain on sale of properties is a result of the sale of one senior living community in January 2014, two senior living communities in June 2014, three senior living communities in October 2014, one senior living community in August 2013 and two rehabilitation hospitals in December 2013.

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 is primarily because of residents fees and services from five managed senior living communities acquired in 2013 and two managed senior living communities acquired in 2014. These acquisitions represent $15,109, or 93.7%, of the net increase in residents fees and services.

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, salaries and benefits of property level personnel, repairs and maintenance expense, cleaning expense and other direct costs of operating these properties. The increase in property operating expenses is primarily due to the acquisitions described above.

Net operating income.  NOI increased because of the changes in rental income, 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 consolidated reconciliation of NOI to net income are included below in “Non‑GAAP Financial Measures”.

Depreciation expense.  Depreciation expense increased primarily as a result of acquisitions of managed senior living communities since January 1, 2013.

Interest expense.  Interest expense for our managed senior living communities arises from mortgage debts secured by certain of these properties. The decrease in interest expense is the result of the repayment at maturity of two mortgages in June 2014 that had an aggregate principal balance of approximately $35,807 and a weighted average annual interest rate of 5.83%, as well as the regularly scheduled amortization of our mortgaged debt. Also, in December 2014 we prepaid one mortgage maturing in July 2015 with a principal balance of approximately $11,308 and an interest rate of 6.37%.

Loss on early extinguishment of debt. Loss on early extinguishment of debt is a result of the December 2014 mortgage prepayment described in interest expense changes above.

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 because of an increase in occupancy and an increase in the average monthly rate of 0.6% charged to residents at the 39 communities we have owned continuously since January 1, 2013.

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 expenses increased principally because of increases in utility expenses, real estate taxes, insurance, and other direct costs of operating properties.

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, comparable properties, is shown in the table above.

Rental income.  Rental income increased because of rents from 8 MOBs (10 buildings) we acquired for approximately $1,274,438 since January 1, 2013. Rental income includes non‑cash straight line rent adjustments totaling $8,788 and $6,119 and net amortization of approximately $2,101 and $(3,776) of above and below market lease adjustments for the years ended December 31, 2014 and 2013, 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. The increase in property operating expenses is primarily due to the acquisitions described above.

Net operating income.  NOI increased because of the changes in rental income and property operating expenses described above. The reconciliation of NOI to net income for our MOB segment 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 increased primarily because of our MOB acquisitions since January 1, 2013.

Interest expense.  Interest expense for our MOBs arises from mortgage debts secured by certain of these properties. The increase in interest expense is the result of our assumption of $15,630 of mortgage debt in connection with our acquisition of one MOB (one building) in 2014 with an interest rate of 6.28%, partially offset by the regularly scheduled amortization of our mortgage debts.

Income from discontinued operations.  Income from discontinued operations relates to our MOBs classified as held for sale since January 1, 2013. During the year ended December 31, 2014, we sold three MOBs (three buildings) that were previously classified as discontinued operations. The decrease in income is primarily due to the sales of these properties. As of December 31, 2014, we had one MOB (four buildings) classified as held for sale.

Impairment of assets from discontinued operations.  During the year ended December 31, 2014, we recorded asset impairment adjustments of $333 to increase the carrying value of the three MOBs (three buildings) we sold in 2014 to their sales price.  We also recorded impairment of assets charges of $4,710 to reduce the carrying value of one MOB (four buildings) currently classified as discontinued operations to its estimated net sales price. During the year ended December 31, 2013, we recorded impairment of assets charges of $37,610 to reduce the carrying value of four of our MOBs (seven buildings) to their estimated net sale prices.

Net income	$	78,173	$	76,368	$	1,805	2.4	%

Rental income.  Rental income increased as a result of an increase in rents and occupancy at certain comparable properties since January 1, 2013, offset by lower net non‑cash items affecting rental income. Rental income includes non‑cash straight line rent adjustments totaling $3,810 and $5,689 and net amortization of approximately $(2,798) and $(3,672) of above and below market lease adjustments for the years ended December 31, 2014 and 2013, 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 expenses increased principally because of increases in salaries and benefit costs of property level personnel, repairs and maintenance expenses, utility expenses, and other direct costs of operating properties.

Net operating income.  NOI decreased because of the 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 consolidated reconciliation of NOI to net income are included below in “Non‑GAAP Financial Measures”.

Depreciation expense.  Depreciation / amortization expense decreased primarily because of a reduction in amortization of acquired real estate leases and obligations that we amortize over the respective lease terms due to certain of these assets being fully amortized, partially offset by an increase in the amortization of leasing costs and an increase in depreciation expense due to capital expenditures.

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

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

Rental income.  Rental income includes non‑cash straight line rent adjustments totaling approximately $550 and $1,129 for the years ended December 31, 2014 and 2013, respectively. Rental income also includes amortization of approximately $221 of acquired real estate leases and obligations for the years ended December 31, 2014 and 2013.

Depreciation expense.  Depreciation expense remained consistent as there were no wellness center acquisitions nor capital improvement funding since January 1, 2013 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 pursuant to our business management agreement with RMR LLC, equity compensation expense, legal and accounting fees and other costs relating to our status as a publicly traded company. General and administrative expenses increased principally as a result of acquisitions of senior living communities and MOBs for approximately $1,407,217 since January 1, 2013, partially offset by the sale of six senior living communities and three MOBs (three buildings) in 2014 for $27,325 and the sale of one senior living community and two rehabilitation hospitals in 2013 for $92,550.

Acquisition related costs.  Acquisition related costs represent legal and due diligence costs incurred in connection with our acquisition activity during 2014 and 2013. The increase in acquisition related costs is a result of an increase in acquisitions in 2014.

Impairment of assets. In 2013, we recorded an impairment of assets charge of $1,304 related to one property to reduce its carrying value to its estimated sales price.

Dividend income. Dividend income recognized is a result of dividends received in 2014 and 2013 from our investment in EQC. The decrease in dividend income in 2014 is a result of reduced dividends declared and paid by EQC in 2014 compared to 2013.

Interest and other income.Interest and other income decreased slightly in 2014 as a result of having less investable cash on hand.

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 an annual interest rate of LIBOR plus 140 basis points, partially offset by the prepayment of one mortgage in September 2013 encumbering two of our wellness centers for $13,579 with a weighted average annual interest rate of 6.9%, as well as lower borrowing costs and fees under our revolving credit facility. Our weighted average balance outstanding and interest rate under our revolving credit facility was $60,288 and 1.4%, and $70,912 and 1.6%, for the years ended December 31, 2014 and 2013, respectively.

Loss on early extinguishment of debt.  In September 2013, we prepaid a mortgage encumbering two of our wellness centers for $13,579 that had a maturity date later in 2013. As a result of the premiums paid to prepay these mortgages, we recorded an aggregate loss on early extinguishment of debt of $259. In September 2013, we amended our revolving credit facility agreement, resulting in a loss on early extinguishment of debt of $538 related to the write off of certain capitalized but unamortized costs of the prior revolving credit facility agreement.

Equity in earnings 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 FFO, Normalized FFO and NOI for the years ended December 31, 2015, 2014 and 2013. These measures should be considered in conjunction with net income, operating income and cash flow

89

from operating activities as presented in our consolidated statements of comprehensive income and 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, 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 and we exclude acquisition related costs, loss on distribution to common shareholders of RMR Inc. common stock, gains and losses on early extinguishment of debt, gains and losses on lease terminations and losses 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 qualification for taxation as a REIT, limitations in our revolving credit facility and term loan agreements and our public debt covenants, the availability to us 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.

Our calculations of FFO and Normalized FFO for the years ended December 31, 2015, 2014 and 2013 and reconciliations of FFO and Normalized FFO to net income, the most directly comparable financial measure under GAAP reported in our consolidated financial statements, appear in the following table.

(1) During 2014, we sold six senior living communities and three MOBs (three buildings) for $27,325 and recognized a gain on sale of approximately $5,453. During 2013, we sold two rehabilitation hospitals and one senior living community for $92,550 and recognized a gain on sale of approximately $37,392.

(2) During 2015, we recorded a net impairment of assets charge of $194 to adjust the carrying value of three of our properties to their estimated sale price less costs to sell. During 2014, we recorded a net impairment of assets adjustment of $10 to adjust the carrying value of two of our properties to their estimated sale price less costs to sell. During 2013, we recorded an impairment of assets charge of $7,989 to reduce the carrying value of five of our properties to their estimated sale price less costs to sell.

(3) During 2015, we recorded an impairment of assets charge of $602 to reduce the carrying value of one MOB (four buildings) to its estimated sale price less costs to sell. During 2014, we recorded a net impairment of assets charge of $4,377 to adjust the carrying value of four MOBs (seven buildings) to their estimated sales price less costs to sell. During 2013, we recorded an impairment of assets charge of $37,610 to reduce the carrying value of four MOBs (seven buildings) to their estimated sale price less costs to sell.

(4) Amounts represent incentive fees under our business management agreement payable in common shares after the end of each calendar year calculated: (i) prior to 2014 based upon increases in Normalized FFO per share, and (ii) beginning in 2014 based on common share total return.  In calculating net income in accordance with GAAP, we recognize estimated business management incentive fee expense, if any, each quarter.  Although we recognize this expense, if any, each quarter for purposes of calculating net income, we do not include these amounts in the calculation of Normalized FFO until the fourth quarter, which is when the actual expense amount for the year is determined. 

(5) In 2015, we recognized a $38,437 non-cash loss on the distribution of shares of class A common stock of RMR Inc. to our shareholders as a result of the closing price of RMR Inc.’s shares being lower than our carrying amount per share on the distribution date.

(6) In 2015, we recorded losses on early extinguishment of debt totaling $1,604 related to the termination of a bridge loan commitment, an amendment to our revolving credit facility agreement and the prepayment of our $250,000 4.30% senior unsecured notes due January 2016. Also in 2015, we prepaid certain mortgages and recorded a loss

91

on early extinguishment of debt of approximately $290. In 2014, we recorded a net loss on early extinguishment of debt of approximately $12 in connection with the prepayment of two mortgages. In September 2013, we recorded a loss on early extinguishment of debt of approximately $538 in connection with an amendment to our revolving credit facility agreement. Also in 2013, we prepaid certain mortgages and recorded a loss on early extinguishment of debt of approximately $259.

Property Net Operating Income (NOI)

We calculate NOI as shown below. The calculation of NOI excludes certain components of net income in order to provide results that are more closely related to our property level results of operations. We define NOI as income from our real estate less our property operating expenses. NOI excludes 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. Other REITs and real estate companies may calculate FFO, Normalized FFO or NOI differently than we do.

The calculation of NOI by reporting segment is included above in this Item 7. The following table includes the reconciliation of NOI to net income, the most directly comparable financial measure under GAAP reported in our consolidated financial statements, for the years ended December 31, 2015, 2014 and 2013.

LIQUIDITY AND CAPITAL RESOURCES

Our principal sources of funds to meet operating and capital expenses and debt service obligations and to pay distributions on our shares are rental income revenues, residents fees and services revenues from our leased and managed communities and borrowings under our revolving credit facility. We believe that these sources will be sufficient to meet our operating expenses and debt service and pay distributions on our common 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 rental rates at, our properties;

· our ability to control operating cost increases;

· our managers’ ability to operate our managed senior living communities so as to profitably increase our returns; and

· our ability to 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 year ended December 31, 2015 compared to the year ended December 31, 2014 were as follows: (i) cash provided by operating activities increased from $350.9 million in 2014 to $405.5 million in 2015; (ii) cash used for investing activities decreased from $1.3 billion in 2014 to $1.2 billion in 2015; and (iii) cash flows from financing activities decreased from $901.5 million in 2014 to $817.6 million in 2015.

93

The increase in cash provided by operating activities for the year ended December 31, 2015 compared to the prior year was due primarily to increased operating cash flow from our acquisitions in 2015. Cash used in investing activities for the year ended December 31, 2015 slightly decreased from the prior year, primarily due to less cash funding for acquisitions in 2015 compared to 2014, partially offset by the investment in class A common stock of RMR Inc. The decrease in cash provided by financing activities for the year ended December 31, 2015 compared to the prior year was due primarily to (i) proceeds received from our issuance of $650.0 million of senior unsecured notes and borrowings under our $350.0 million term loan agreement in 2014 as compared to 2015; (ii) increased distributions to our common shareholders, the redemption of $250.0 million of senior unsecured notes and increased repayments of mortgage debts, partially offset by higher proceeds from our issuance of common shares, borrowings under our $200.0 million term loan agreement and higher net borrowings under our revolving credit facility in 2015.

Our Investment and Financing Liquidity and Resources

As of December 31, 2015, we had $37.7 million of cash and cash equivalents and $225.0 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 and the cash flow from our operations 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 these funding sources 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 $1.0 billion unsecured revolving credit facility with a group of institutional lenders. In September 2015, we partially exercised the accordion feature under our revolving credit facility agreement, which increased the maximum borrowings available under this facility to $1.0 billion from the previous amount of $750.0 million. All other material terms of the revolving credit facility remained unchanged. 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, our revolving credit facility agreement includes a feature under which the maximum borrowing availability under the facility may be increased to up to $1.5 billion in certain circumstances. Our revolving credit facility requires interest to be paid at LIBOR plus a premium, which was 130 basis points per annum as of December 31, 2015. 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 re-borrow funds available under our revolving credit facility until maturity, and no principal repayment is due until maturity. As of December 31, 2015, the annual interest rate required on borrowings under our revolving credit facility was 1.69%. As of December 31, 2015 and February 22, 2016, we had $775.0 million and $593.0 million outstanding under our revolving credit facility, respectively.

When significant amounts are outstanding under our revolving credit facility or as the maturity dates of our revolving credit facility, term loans, mortgages and senior unsecured notes 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. We may also assume mortgage debts in connection with our acquisitions of properties or place new mortgages on properties we own.

Our revolving credit facility and term loan agreements provide that, with certain exceptions, a subsidiary of ours is required to guaranty our obligations under our revolving credit facility and term loans only if that subsidiary has separately incurred debt (other than nonrecourse debt), within the meaning specified in the revolving credit facility or term loan agreements, or provided a guarantee of debt incurred by us or any of our other subsidiaries.

In May 2014, we entered into an agreement pursuant to which we obtained a $350.0 million unsecured term loan. This term loan matures on January 15, 2020, and is prepayable without penalty at any time.  In addition, this term loan includes a feature under which maximum borrowings may be increased to up to $700.0 million in certain circumstances. This term loan requires interest to be paid at LIBOR plus a premium (currently 140 basis points per annum) that is subject to adjustment based upon changes to our credit ratings.

94

In February 2015, we repaid at maturity a mortgage for approximately $29.2 million with an annual interest rate of 6.02%. In April 2015, we prepaid a mortgage for approximately $6.3 million with an annual interest rate of 5.81% that had a maturity date in October 2015. In May 2015, we prepaid four mortgages of approximately $15.1 million that had maturity dates in July 2015 and required weighted average annual interest of 5.70%. In June 2015, we repaid at maturity a mortgage for approximately $4.9 million with an annual interest rate of 5.65%. Also in June 2015, we prepaid a mortgage for approximately $4.4 million that had a maturity date in October 2015 and required annual interest of 5.81%. In October 2015, we prepaid two mortgages of approximately $52.0 million that had maturity dates in January 2016 and required weighted average annual interest of 5.64%. In November 2015, we redeemed our $250.0 million of 4.30% senior unsecured notes due January 2016. We funded all of the foregoing repayments with cash on hand and borrowings under our revolving credit facility.

In January 2015, we acquired 23 MOBs (23 buildings) for approximately $532.0 million, excluding closing costs and working capital adjustments and including the assumption of approximately $30.0 million of mortgage debts with a weighted average annual interest rate of 4.73%.  These MOBs contain approximately 2.2 million leasable square feet and are located in 12 states. We funded this acquisition using cash on hand, borrowings under our revolving credit facility and the assumption approximately $30.0 million of mortgage debts with a weighted average annual interest rate of 4.73%.

In December 2014, we entered into an agreement to acquire 38 senior living communities with 3,439 living units for $790.0 million, excluding closing costs. In May 2015, we acquired 37 of these 38 senior living communities and in September 2015 we acquired the one remaining community. We funded the acquisition of these senior living communities using cash on hand, borrowings under our revolving credit facility and the assumption of approximately $151.5 million of mortgage debts with a weighted average interest rate of 4.57%.

In May 2015, we acquired one senior living community with 40 private pay independent living units for $9.8 million, excluding closing costs. This senior living community is adjacent to another community that we own which is managed by Five Star. The operations of this community and the community we previously owned are now conducted as a single integrated community under one management agreement. We funded this acquisition using cash on hand and borrowings under our revolving credit facility.

In May 2015, we sold all 250,000 of our common shares of EQC for proceeds of approximately $6.6 million, net of transaction costs.

On June 5, 2015, we acquired 5,272,787 shares of class A common stock of RMR Inc. for approximately $60.7 million, excluding transaction costs. As payment for the RMR Inc. shares, we issued 2,345,000 of our common shares valued at approximately $44.5 million and paid the remainder of the purchase price in cash. On December 14, 2015, we distributed 2,635,379 of the RMR Inc. shares we acquired to our shareholders as a special non-cash distribution, valued at $11.89 per share, or $31.3 million. For more information regarding this investment, see Notes 4 and 5 to the Notes to our Consolidated Financial Statements included in Part IV, Item 15 of this Annual Report on Form 10-K, which is incorporated herein by reference.

In September 2015, we acquired one senior living community with 84 living units for approximately $18.3 million, excluding closing costs. We funded this acquisition using cash on hand and borrowings under our revolving credit facility.

In September 2015, we entered into a term loan agreement with Wells Fargo Bank, National Association and a syndicate of other lenders, pursuant to which we obtained a $200.0 million unsecured term loan. This term loan matures on September 28, 2022, and is prepayable without penalty beginning September 29, 2017. In addition, this term loan includes a feature under which maximum borrowings may be increased to up to $400.0 million in certain circumstances. This term loan requires interest to be paid at LIBOR plus a premium (currently 180 basis points per annum) that is subject to adjustment based upon changes to our credit ratings. We used the net proceeds from this term loan to partially repay amounts outstanding under our revolving credit facility.

In February 2016, we sold $250.0 million in aggregate principal amount of 6.25% senior unsecured notes due

95

2046, raising net proceeds of approximately $241.5 million after underwriting discounts and estimated expenses. We have also granted the underwriters an option to purchase up to an additional $37.5 million in aggregate principal amount of the notes.We used the net proceeds of this offering to repay amounts outstanding under our revolving credit facility and for general business purposes.

In February 2015, we sold one senior living community for approximately $0.3 million, excluding closing costs. In April 2015, we sold one MOB (four buildings) for $1.5 million, excluding closing costs. In July 2015, we sold one senior living community with 12 skilled nursing units for approximately $0.2 million, excluding closing costs. In August 2015, we sold one senior living community with 63 skilled nursing units for approximately $0.9 million, excluding closing costs. In December 2015, we sold one senior living community with 117 skilled nursing units for approximately $0.02 million, excluding closing costs.

In January 2016, we entered into an agreement to acquire one senior living community located in Georgia with 38 private pay units for $8.4 million, excluding closing costs. We expect to acquire this community using a TRS structure, and that it will be managed by Five Star on substantially similar terms as other communities it currently manages on our behalf.  This acquisition is subject to various conditions; accordingly we can provide no assurance that we will purchase this property, that the acquisition or related expected management agreement with Five Star will not be delayed or that the terms will not change.

In February 2016, we acquired one MOB (three buildings) in Minnesota with approximately 128,000 square feet for $22.7 million, excluding closing costs.

During the year ended December 31, 2015, pursuant to the terms of our existing leases with Five Star, we purchased $21.4 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 $1.7 million. We used cash on hand and borrowings under our revolving credit facility to fund these purchases.

During the years ended December 31, 2015 and 2014, cash expenditures made and 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):

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 a portion of the net proceeds of this offering to repay borrowings under our revolving credit facility and for general business purposes.

97

On January 11, 2016, we declared a quarterly distribution of $0.39 per common share, or $92.6 million, to our common shareholders of record on January 22, 2016 for the quarter ended December 31, 2015. We expect to pay this distribution to shareholders on or about February 23, 2016 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.

As of December 31, 2015, 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 or expenses, results of operations, liquidity, capital expenditures or capital resources.

Debt Covenants

Our principal debt obligations at December 31, 2015 were: (1) outstanding borrowings under our $1.0 billion unsecured revolving credit facility; (2) five public issuances of senior unsecured notes, including: (a) $400.0 million principal amount at an annual interest rate of 3.25% due 2019, (b) $200.0 million principal amount at an annual interest rate of 6.75% due 2020, (c) $300.0 million principal amount at an annual interest rate of 6.75% due 2021, (d) $250.0 million principal amount at an annual interest rate of 4.75% due 2024 and (e) $350.0 million principal amount at an annual interest rate of 5.625% due 2042; (3) our $350.0 million principal amount term loan; (4) our $200.0 million principal amount term loan and (5) $667.5 million aggregate principal amount of mortgages secured by 56 of our properties (57 buildings) with maturity dates between 2016 and 2043. We also have two properties encumbered by capital leases with lease obligations totaling $12.2 million at December 31, 2015; the capital leases expire in 2026. We had $775.0 million outstanding under our revolving credit facility as of December 31, 2015. Our senior unsecured notes are governed by our senior unsecured notes indentures and their supplements. Our revolving credit facility and term loan agreements and our senior unsecured notes indentures and their supplements provide for acceleration of payment of all amounts outstanding upon the occurrence and continuation of certain events of default, such as, in the case of our revolving credit facility and term loan agreements, a change of control of us, which includes RMR LLC ceasing to act as our business manager and property manager. Our senior unsecured notes indentures and their supplements and our revolving credit facility and term loan agreements also 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 and require us to maintain various financial ratios, and our revolving credit facility and term loan agreements contains covenants which restrict our ability to make distributions in certain circumstances. As of December 31, 2015, we believe we were in compliance with all of the covenants under our senior unsecured notes indentures and their supplements, our revolving credit facility and term loan agreements and our other debt obligations.

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

98

Our senior unsecured notes indentures and their supplements contain cross default provisions to any other debts of more than $20.0 million ($50 million or more in the case of our senior unsecured notes indenture and supplement entered into in February 2016). 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 RMR LLC, RMR Inc. and others related to them. For example, we have no employees and the personnel and various services we require to operate our business are provided to us by RMR LLC pursuant to management agreements, and RMR Inc. is the managing member of RMR LLC. ABP Trust, which is owned by our Managing Trustees, is the controlling shareholder of RMR Inc. We own shares of class A common stock of RMR Inc. We also have relationships and historical and continuing transactions with other companies to which RMR LLC provides management services and which have trustees, directors and officers who are also trustees, directors or officers of us, RMR LLC or RMR Inc., including: Five Star, which is our former subsidiary, our largest tenant and a manager of certain of our senior living communities and of which we are the largest stockholder; D&R Yonkers LLC, which is owned by our President and Chief Operating Officer and Five Star’s treasurer and chief financial officer and to which one of our TRSs subleases a portion of a senior living community we own in order to accommodate certain requirements of New York healthcare licensing laws; SIR, from which we purchased entities owning 23 MOBs that SIR acquired in connection with the acquisition by SIR of Cole Corporate Income Trust, Inc., or CCIT; and AIC, of which we, ABP Trust, Five Star and four other companies to which RMR LLC provides management services each own approximately 14.3%. We and the other six shareholders of AIC participate in a combined property insurance program arranged and reinsured in part by AIC. For further information about these and other such relationships and related person transactions, please see Note 5 to our Consolidated Financial Statements included in Part IV, Item 15 of this Annual Report on Form 10-K, which is incorporated herein by reference, our other filings with the SEC and our definitive Proxy Statement for our 2016 Annual Meeting of Shareholders to be filed within 120 days after the close of the fiscal year ended December 31, 2015. For more information about these transactions and relationships and about the risks that may arise as a result of these and other related person transactions and relationships, please see elsewhere in this Annual Report on Form 10-K, including “Warning Concerning Forward Looking Statements” and Part I, Item 1, “Business” and Part I, Item 1A “Risk Factors.” Our filings with the SEC and copies of certain of our agreements with these related parties, including our business management agreement and property management agreement with RMR LLC, our leases, forms of management agreements and related pooling agreements with Five Star, our agreements with D&R Yonkers LLC and its owners, the purchase and sale agreement for the purchase from SIR of entities owning CCIT’s 23 MOBs and our shareholders agreement with AIC and its six other shareholders, are publicly available as exhibits to our public filings with the SEC and accessible at the SEC’s website, www.sec.gov. We may engage in additional transactions with related persons, including businesses to which RMR LLC or its affiliates provide management services.

Critical Accounting Policies

Our critical accounting policies are those that will have the most impact on the reporting of our financial condition and results of operations and those requiring significant judgments and estimates. We believe that our judgments and estimates are consistently applied and produce financial information that fairly presents our results of operations. Our most critical accounting policies involve our investments in real property. These policies affect our:

· allocation of purchase prices among various asset categories, including allocations to above and below market leases for properties qualifying as acquired businesses under FASB Accounting Standards Codification 805, Business Combinations, and the related impact on the recognition of rental income and depreciation and amortization expense;

· assessment of the carrying values and impairments of long lived assets; and

· classification of leases.

We allocate the acquisition cost of each property investment to various property components such as land, buildings and improvements and intangibles based on their fair values, and each component generally has a different useful

99

life. For real estate acquired, we record building, land and improvements, and, if applicable, the value of in-place leases, the fair market value of above or below market leases and customer relationships at fair value. We allocate the excess, if any, of the consideration over the fair value of assets acquired to goodwill. We base purchase price allocations and the determination of useful lives on our estimates and, under some circumstances, studies from independent real estate appraisal firms to provide market information and evaluations that are relevant to management's purchase price allocations and determinations of useful lives; however, management is ultimately responsible for the purchase price allocations and determination of useful lives.

We compute depreciation expense using the straight line method over estimated useful lives of up to 40 years. We do not depreciate the allocated cost of land. We amortize capitalized above market lease values (included in acquired real estate leases) as a reduction to rental income over the remaining non‑cancelable terms of the respective leases. We amortize capitalized below market lease values (presented as acquired real estate lease obligations) as an increase to rental income over the remaining terms of the respective leases. We amortize the value of in place leases exclusive of the value of above market and below market in place leases to expense over the remaining non‑cancelable periods of the respective leases. If a lease is terminated prior to its stated expiration, all unamortized amounts relating to that lease are written off. Purchase price allocations require us to make certain assumptions and estimates. Incorrect assumptions and estimates may result in inaccurate depreciation and amortization charges over future periods.

We periodically evaluate our properties for impairment. 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. If indicators of impairment are present, we evaluate the carrying value of the related property by comparing it to the expected future undiscounted cash flows to be generated from that property. If the sum of these expected future cash flows is less than the carrying value, we reduce the net carrying value of the property to its estimated fair value. This analysis requires us to judge whether indicators of impairment exist and to estimate likely future cash flows. If we misjudge or estimate incorrectly or if future tenant operations, market or industry factors differ from our expectations we may record an impairment charge that is inappropriate or fail to record a charge when we should have done so, or the amount of any such charges may be inaccurate.

Each time we enter a new lease or materially modify an existing lease, we evaluate its classification as either a capital or operating lease. The classification of a lease as capital or operating affects the carrying value of a property, as well as our recognition of rental payments as revenue. These evaluations require us to make estimates of, among other things, the remaining useful life and fair market value of a leased property, appropriate discount rates and future cash flows. Incorrect assumptions or estimates may result in misclassification of our leases.

These policies involve significant judgments made based upon experience, including judgments about current valuations, ultimate realizable value, estimated useful lives, salvage or residual value, the ability and willingness of our tenants to perform their obligations to us, and the current and likely future operating and competitive environments in which our properties are operated. In the future, we may need to revise our carrying value assessments to incorporate information which is not now known, and such revisions could increase or decrease our depreciation expense or impairment charges related to properties we own, result in the classification of our leases as other than operating leases or decrease the carrying values of our assets.

Impact of Inflation

Inflation in the past several years in the United States has been modest. Future inflation might have both positive and negative impacts on our business. Inflation might cause the value of our real estate to increase. In an inflationary environment, the percentage rents which we receive based upon a percentage of our tenants’ revenues should increase. Further, inflation may permit us to increase rents upon renewal or enter new leases for the leased space for increased rent amounts. Offsetting these benefits, inflation might cause our costs of equity and debt capital and operating costs to increase. An increase in our capital costs or in our operating costs may result in decreased earnings unless it is offset by increased revenues. In periods of rapid inflation, our tenants’ or managers’ operating costs may increase faster than revenues, which may have an adverse impact upon us if our tenants’ or managers’ operating income from our properties becomes insufficient to pay our rents or returns. To mitigate the adverse impact of increased tenant financial distress upon us, we

100

generally require our tenants to provide guarantees for our rent. To mitigate the adverse impact of any increased cost of debt capital in the event of material inflation, we previously have purchased interest rate cap agreements and we may enter into additional interest rate hedge arrangements in the future. The decision to enter into these agreements was and will be based on various factors, including the amount of our floating rate debt outstanding, our belief that material interest rate increases are likely to occur, the costs of and our expected benefit from these agreements and upon requirements of our borrowing arrangements.

Impact of Government Reimbursement

As of December 31, 2015,  approximately 97% of our NOI was generated from properties where a majority of the revenue is derived from private resources, and the remaining 3% of our NOI was generated from properties where a majority of the revenue was derived from Medicare and Medicaid payments.  Nonetheless, we own and our tenants and managers operate facilities in many states and 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, as well as existing regulations that impact these matters. Further, there are other existing and recently enacted legislation, and related litigation, related to government payments, insurance and healthcare delivery. Examples of these, and other information regarding such matters and developments, are provided under the caption “Business—Government Regulation and Reimbursement” above in this Annual Report on Form 10-K. We cannot estimate the type and magnitude of these matters. However, these matters could result in the failure of Medicare, Medicaid or private payment rates to cover our or our tenants’ and managers’ 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.

Seasonality

Skilled nursing and assisted living operations have historically reflected modest seasonality. During fourth quarter holiday periods, residents at such facilities are sometimes discharged to join in family celebrations and admission decisions are often deferred. The first quarter of each calendar year usually coincides with increased illness among residents which can result in increased costs or discharges to hospitals. As a result of these factors and others, these operations sometimes produce greater earnings in the second and third quarters of each calendar year and lesser earnings in the fourth and first calendar quarters. We do not expect these seasonal differences to have a material impact upon the ability of our tenants to pay our rent or our ability to fund our managed senior living operations or our other businesses. Our MOBs and wellness center business do not typically experience seasonality.

Impact of Climate Change

The current political debate about global climate change has resulted in various treaties, laws and regulations which are intended to limit carbon emissions. We believe these laws being enacted or proposed may cause energy costs at our properties to increase in the future. In an effort to reduce the effects of any increased energy costs in the future, we and our manager, RMR LLC, continuously study ways to improve the energy efficiency at all of our properties. RMR LLC is a member of the Energy Star Partner program, a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy which is focused on promoting energy efficiency and sustainability at commercial properties through its “ENERGY STAR” label program, and a member of the U.S. Green Building Council, a nonprofit organization focused on promoting energy efficiency and sustainability at commercial properties through its LEED® green building certificate program. We do not expect the direct impact of these possible increases in energy costs resulting from laws designed to address climate change to be material to our results of operations because most of the increased costs either may be the responsibility of our tenants directly or in large part may be passed through by us to our tenants as additional lease payments or, in the longer term, would be passed through as higher charges paid by the patients, residents and other customers of our properties; however, increased costs incurred by our managers may affect their ability to pay us our minimum returns and may prevent or reduce any additional returns we may receive. Although we do not believe it is likely

101

in the foreseeable future, laws enacted to mitigate climate change may make some of our buildings obsolete or cause us to make material investments in our properties which could materially and adversely affect our financial condition and results of operations or the financial condition of our tenants or managers and their ability to pay rent or returns to us.

There have recently been severe weather activities in different parts of the country that some observers believe evidence global climate change. Such severe weather that may result from climate change may have an adverse effect on individual properties we own. We mitigate these risks by owning a geographically diversified portfolio of properties and by procuring insurance coverage we believe adequate to protect us from material damages and losses from such activities. However, there can be no assurance that our mitigation efforts will be sufficient or that storms that may occur due to future climate change or otherwise could not have a material adverse effect on our business.

Item 7A.  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. 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.

At December 31, 2015, our outstanding fixed rate debt included the following (dollars in thousands):

102

			Annual		Annual
	Principal		Interest		Interest			Interest

(1) In February 2016, we sold $250.0 million in aggregate principal amount of 6.25% senior unsecured notes due 2046.  These notes are not included in the above table.

(2) The principal balances, annual interest rates and annual interest expense are based on 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 prepaid this debt in January 2016.

No principal repayments are due under our unsecured notes until maturity. Our mortgage debts require principal and interest payments through maturity pursuant to amortization schedules. Because these debts require interest to be paid 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 $21.7 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 December 31, 2015, 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 $19.8 million.

103

Our senior unsecured notes and certain 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 December 31, 2015, our current floating rate debt obligations consisted of our $1.0 billion unsecured revolving credit facility, under which we had $775.0 million outstanding, our $350.0 million unsecured term loan and our $200.0 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 $350.0 million term loan matures on January 15, 2020, and our $200.0 million term loan matures on September 28, 2022. Our $350.0 million term loan is prepayable without penalty at any time. Our $200.0 million term loan is prepayable without penalty beginning September 29, 2017.

Borrowings under our revolving credit facility and term loans are in U.S. dollars and interest is required to be paid 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 loans, 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 December 31, 2015 (dollars in thousands except per share amounts):

	Impact of Changes in Interest Rates
							Annual
	Interest Rate		Outstanding		Total Interest		Earnings per Share
	Per Year(1)		Debt		Expense Per Year		Impact(2)
At December 31, 2015	1.76	%	$	1,325,000	$	23,320	$	0.10
100 basis point increase	2.76	%	$	1,325,000	$	36,570	$	0.16

(1) Weighted based on interest rates and outstanding borrowings as of December 31, 2015.

(2) Based on weighted average number of shares outstanding (basic and diluted) for the year ended December 31, 2015.

The following table presents the impact a 100 basis point increase in interest rates would have on our annual floating rate interest expense at December 31, 2015 if we were fully drawn on our revolving credit facility and our term loans remained outstanding (dollars in thousands except per share amounts):

	Impact of Changes in Interest Rates
							Annual
	Interest Rate		Outstanding		Total Interest		Earnings per Share
	Per Year(1)		Debt		Expense Per Year		Impact(2)
At December 31, 2015	1.75	%	$	1,550,000	$	27,125	$	0.12
100 basis point increase	2.75	%	$	1,550,000	$	42,625	$	0.18

(1) Weighted based on the interest rates and outstanding borrowings as of December 31, 2015.

104

(2) Based on weighted average number of shares outstanding (basic and diluted) for the year ended December 31, 2015.

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 amount outstanding 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 arrangements from time to time to mitigate our exposure to changes in interest rates.

Item 8.  Financial Statements and Supplementary Data.

The information required by this item is included in Part IV, Item 15 of this Annual Report on Form 10‑K.

Item 9.  Changes in and Disagreements With Accountants on Accounting and Financial Disclosure.

None.

Item 9A.  Controls and Procedures.

As of the end of the period covered by this Annual Report on Form 10-K, 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 Exchange Act, 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 December 31, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management Report on Assessment of Internal Control Over Financial Reporting

We are responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control system is designed to provide reasonable assurance to our management and Board of Trustees regarding the preparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2015. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework  (2013 framework). Based on our assessment, we believe that, as of December 31, 2015, our internal control over financial reporting is effective.

Ernst & Young LLP, the independent registered public accounting firm that audited our 2015 consolidated financial statements included in this Annual Report on Form 10‑K, has issued an attestation report on our internal control over financial reporting. The report appears elsewhere herein.

Item 9B.  Other Information.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees and Shareholders of Senior Housing Properties Trust

We have audited the accompanying consolidated balance sheets of Senior Housing Properties Trust (the “Company”) as of December 31, 2015 and 2014, and the related consolidated statements of comprehensive income, shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2015. Our audits also included the financial statement schedule listed in the Index at Item 15(a). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Senior Housing Properties Trust at December 31, 2015 and 2014, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2015, in conformity with U.S. generally accepted accounting principles.  Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Senior Housing Properties Trust’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 23, 2016 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees and Shareholders of Senior Housing Properties Trust:

We have audited Senior Housing Properties Trust’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). Senior Housing Properties Trust’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in Item 9A of Senior Housing Properties Trust’s Annual Report on Form 10-K under the heading Management Report on Assessment of Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Senior Housing Properties Trust maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 2015 consolidated financial statements of Senior Housing Properties Trust and our report dated February 23, 2016 expressed an unqualified opinion thereon.

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

Note 1. Organization

We are a real estate investment trust, or REIT, organized under Maryland law. At December 31, 2015, we owned 427 properties (451 buildings) located in 43 states and Washington, D.C.

Note 2. Summary of Significant Accounting Policies

BASIS OF PRESENTATION.  Our consolidated financial statements include the accounts of Senior Housing Properties Trust, or SNH, we, us or our, and our subsidiaries, all of which are 100% owned directly or indirectly by us. All intercompany transactions and balances with or among our consolidated subsidiaries have been eliminated. Accounting principles generally accepted in the United States, or GAAP, require us to make estimates and assumptions that may affect the amounts reported in these financial statements and related notes. The actual results could differ from these estimates.We have made reclassifications to the prior years’ financial statements to conform to the current year’s presentation. These reclassifications had no effect on net income or shareholders’ equity.

We have determined that, in 2015, certain of our wholly owned taxable REIT subsidiaries, or TRSs, were variable interest entities, or VIEs, as defined under the Consolidation Topic of the Financial Accounting Standards Board, or FASB, Accounting Standards Codification,or the Codification. We have concluded that we must consolidate each of these TRSs because we are the entity with the power to direct the activities that most significantly impact such VIEs’ performance and we have the obligation to absorb losses or the right to receive benefits from each VIE that could be significant to the VIE and are, therefore, the primary beneficiary of each VIE. The assets of our TRSs classified as VIEs were$2,879as of December 31, 2015 and consist primarily of working capital of one of our senior living managers.  The liabilities of our TRSs classified as VIEs were$950 as of December 31, 2015 and consist primarily of payables to one of our senior living managers. The assets of our TRSsare available to satisfy our TRSs’obligations and we have guaranteed certain obligations of our TRSs.

REAL ESTATE PROPERTIES.  We record properties at our cost and calculate depreciation on real estate investments on a straight line basis over estimated useful lives generally up to 40 years. When we acquire a property, we estimate the purchase price allocations and the useful lives of our properties.

In some circumstances, we engage third party real estate appraisal firms to provide market information and evaluations which are relevant to our purchase price allocations and determinations of useful lives; however, we are ultimately responsible for the purchase price allocations and determinations of useful lives.

We allocate the purchase prices of our properties to land, building and improvements based on determinations of the fair values of these assets assuming the properties are vacant. We determine the fair value of each property using methods similar to those used by third party appraisers. For properties qualifying as acquired businesses under Accounting Standards Codification 805, Business Combinations, we allocate a portion of the purchase price of our properties to above market and below market leases based on the present value (using an interest rate which reflects the risks associated with acquired in place leases at the time each property was acquired by us) of the difference, if any, between (i) the contractual amounts to be paid pursuant to the acquired in place leases and (ii) our estimates of fair market lease rates for the corresponding leases, measured over a period equal to the terms of the respective leases. We allocate a portion of the purchase price to acquired in place leases and tenant relationships based upon market estimates to lease up the property based on the leases in place at the time of purchase.

We amortize capitalized above market lease values (included in acquired real estate leases in our consolidated balance sheets) as a reduction to rental income over the remaining non‑cancelable terms of the respective leases. We amortize capitalized below market lease values (presented as acquired real estate lease obligations in our consolidated balance sheets) as an increase to rental income over the non‑cancelable periods of the respective leases. Such amortization resulted in an increase in rental income of $4,060 during the year ended December 31, 2015, an increase in rental income of $2,322 during the year ended December 31, 2014, and a reduction in rental income of $3,656 during the year ended

F-8

December 31, 2013. We amortize the value of in place leases exclusive of the value of above market and below market in place leases to expense over the remaining non‑cancelable periods of the respective leases. Such amortization included in depreciation totaled $80,040,  $38,970 and$22,718, during the years ended December 31, 2015, 2014 and 2013, respectively. If a lease is terminated prior to its stated expiration, the unamortized amount relating to that lease is written off.

CASH AND CASH EQUIVALENTS.  We carry cash and cash equivalents, consisting of overnight repurchase agreements and short term investments with original maturities of three months or less at the date of purchase, at cost plus accrued interest, which approximates fair value.

RESTRICTED CASH.  Restricted cash consists of amounts escrowed for real estate taxes, insurance and capital expenditures at certain of our mortgaged properties and security deposits for residents of our managed senior living communities.

INVESTMENTS IN AVAILABLE FOR SALE SECURITIES.  At December 31, 2014, we owned 250,000 common shares of Equity Commonwealth (f/k/a CommonWealth REIT), or EQC. We sold all 250,000 of our EQC common shares in May 2015 for net proceeds of $6,571. We recognized a gain on the sale of these shares in the amount of $71 during the second quarter of 2015, which is included in interest and other income in our consolidated statements of comprehensive income.

We owned 4,235,000 common shares, or 8.6% at December 31, 2015 and 2014, of Five Star Quality Care, Inc., or Five Star. We classify these shares of Five Star as available for sale securities and carry them at fair value, with unrealized gains and losses reported as a component of shareholders’ equity. Cumulative other comprehensive income shown in our consolidated balance sheets includes the net unrealized gain or loss on investments determined as the net difference between the market value of these shares of Five Star calculated by using weighted average quoted market prices on the dates we acquired these shares ($3.36 per share) and on December 31, 2015($3.18 per share). At December 31, 2015 and 2014, our investment in Five Star had a fair value of $13,467 and $17,575, respectively, including an unrealized loss of $747 and an unrealized gain of $3,361, respectively.

In addition, at December 31, 2015, we owned 2,637,408 shares of class A common stock of The RMR Group Inc., or RMR Inc. We also classify these shares of RMR Inc. as available for sale securities and carry them at fair value, with unrealized gains and losses reported as a component of shareholders’ equity. Our historical cost basis for these shares is $69,826. At December 31, 2015, our investment in RMR Inc. had a fair value of $38,005, including an unrealized loss of $31,821 based on RMR Inc.’s quoted share price at December 31, 2015 ($14.41 per share).

We evaluate our investments in available for sale securities to determine if a decline in the fair value below our carrying value is other than temporary. We consider the severity and the duration of the decline, and our ability and intent to hold the investment until recovery when making this assessment. If a decline in fair value is determined to be other than temporary, an impairment loss equal to the difference between the investment’s carrying value and its fair value is recognized in earnings.

See Notes 5 and 7 for further information regarding our investments in Five Star and RMR Inc.

EQUITY METHOD INVESTMENTS.  At December 31, 2015, we owned 14.3% of Affiliates Insurance Company, or AIC’s, outstanding equity. Although we own less than 20% of AIC, we use the equity method to account for this investment because we believe that we have significant influence over AIC because all of our Trustees are also directors of AIC. Under the equity method, we record our percentage share of net earnings from AIC in our consolidated statements of comprehensive income. If we determine there is an “other than temporary impairment” in the fair value of this investment, we would record a charge to earnings. In evaluating the fair value of this investment, we have considered, among other things, the assets and liabilities held by AIC, AIC’s overall financial condition and earning trends, and the financial condition and prospects for the insurance industry generally. See Note 5 for further information regarding our investment in AIC.

F-9

DEFERRED FINANCING FEES.  We capitalize issuance costs related to borrowings and amortize them over the terms of the respective borrowings. During 2015, we capitalized $2,952 of issuance costs, including $1,200 related to an amendment to our revolving credit facility agreement to increase the maximum borrowings under that facility in September 2015, as well as $1,752 related to our $200,000 term loan entered into in September 2015. During 2014, we capitalized $8,039 of issuance costs, including $5,021 related to our issuances of senior unsecured notes in April 2014, as well as $2,819 related to our $350,000 term loan entered into in May 2014, and $199 related to our assumption of a mortgage in May 2014. During 2013, we capitalized $3,326 of issuance costs, including $3,078 related to an amendment to our revolving credit facility agreement in September 2013 and $248 related to our assumption of a mortgage during 2013. During 2015, we wrote off $70 of unamortized deferred financing fees in connection with our prepayment of the outstanding principal balances of ten mortgages encumbering nine properties with an aggregate principal balance of $82,569. We also wrote off $74 of unamortized deferred financing fees in connection with our prepayment of all $250,000 of our 4.30% senior unsecured notes due January 2016 in November 2015. During 2014, we wrote off $357 of unamortized deferred financing fees in connection with our prepayment of the outstanding principal balances of two mortgages totaling $23,234 in October and December 2014. The unamortized gross balance of deferred financing fees and related accumulated amortization was $50,477 and $22,782, and $50,479 and $19,930, at December 31, 2015 and 2014, respectively. At December 31, 2015, the remaining weighted average amortization period is approximately 12.5 years. We expect that the amortization expense relating to the unamortized gross balance of deferred financing fees for the five years subsequent to December 31, 2015 will be $5,514 in 2016, $5,247 in 2017, $3,394 in 2018, $2,639 in 2019, $1,213 in 2020, and $9,688, thereafter.

DEFERRED LEASING COSTS.  Deferred leasing costs include brokerage, legal and other fees associated with our entering leases and are amortized on a straight line basis over the terms of the respective leases. Deferred leasing costs are included in other assets on our consolidated balance sheets. The unamortized gross balance of deferred leasing costs and related accumulated amortization was $21,708 and $5,561, and $14,844 and $3,722 at December 31, 2015 and 2014, respectively. At December 31, 2015, the remaining weighted average amortization period is approximately 6.8 years. We expect that the amortization expense for the five years subsequent to December 31, 2015 will be $2,853 in 2016, $2,528 in 2017, $2,286 in 2018, $1,968 in 2019, $1,583 in 2020, and $4,710, thereafter.

REVENUE RECOGNITION.  We recognize rental income from operating leases on a straight line basis over the term of each lease agreement. We recognize percentage rents when realizable and earned, which is generally during the fourth quarter of the year. For the years ended December 31, 2015, 2014 and 2013, percentage rents earned aggregated $10,062,  $10,155 and$9,226, respectively.

As of December 31, 2015, we owned 65 managed senior living communities, including 55 communities that we acquired since June 2011 and ten senior living communities formerly leased to Sunrise Senior Living, Inc. Sixty of these communities are managed by Five Star, and the remaining five are managed by a private senior living manager. We refer to these 65 communities as the managed senior living communities. We derive our revenues at these managed senior living communities primarily from services our managers provide to residents on our behalf and we record revenues when services are provided. We use the TRS structure authorized by the Real Estate Investment Trust Investment Diversification and Empowerment Act for nearly all of our managed senior living communities.

PER COMMON SHARE AMOUNTS.  We calculate basic earnings per common share by dividing net income by the weighted average number of our common shares of beneficial ownership, $0.01 par value, or our common shares, outstanding during the period. We calculate diluted earnings per common share, or EPS, using the more dilutive of the two class method or the treasury stock method. Unvested share awards and other potentially dilutive common shares and the related impact on earnings, are considered when calculating diluted earnings per share.

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 nearly all of our managed senior living communities to our TRSs, that, unlike most of our subsidiaries, file separate tax returns 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 incurred by us, despite our REIT status.

F-10

The Income Taxes Topic of the Codification prescribes how we should recognize, measure and present in our financial statements uncertain tax positions that have been taken or are expected to be taken in a tax return. Tax benefits are recognized to the extent that it is “more likely than not” that a particular tax position will be sustained upon examination or audit. To the extent the “more likely than not” standard has been satisfied, the benefit associated with a tax position is measured as the largest amount that has a greater than 50% likelihood of being realized upon settlement. We classify interest and penalties related to uncertain tax positions, if any, in our financial statements as a component of general and administrative expense.

SEGMENT REPORTING.  As of December 31, 2015, we have four operating segments, of which three are separate reporting segments. The first reporting segment includes triple net senior living communities that provide short term and long term residential care and other services for residents. The second reporting segment includes managed senior living communities that provide short term and long term residential care and other services for residents. The third reporting segment includes properties leased to medical providers, medical related businesses, clinics and biotech laboratory tenants, or MOBs. Our fourth segment includes the remainder of our operations, including certain properties that offer fitness, wellness and spa services to members, which we do not consider to be sufficiently material as to constitute a separate reporting segment, and all of our other operations.

See Note 9 for further information regarding our reportable operating segments.

NEW ACCOUNTING PRONOUNCEMENTS.  In February 2015, the FASB, issued Accounting Standards Update, or ASU, No. 2015-02, Consolidation.  Among other things, this update changes how an entity determines the primary beneficiary of a VIE. 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 consolidated financial statements.

In April 2015, the FASB issued ASU 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. In August 2015, the FASB clarified the previous ASU and issued ASU No. 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements – Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting, which addresses the presentation of debt issuance costs related to line of credit arrangements. These updates are effective for interim and annual reporting periods beginning after December 15, 2015 and require retrospective application. The implementation of these updates is not expected to cause any material changes to our consolidated financial statements other than the reclassification of debt issuance costs from assets to contra liabilities on our consolidated balance sheets. Debt issuance costs related to our revolving credit facility will remain classified as assets in accordance with ASU 2015-15. When these updates are adopted, the unamortized gross balance of deferred financing fees of $23,950 and $26,339 as of December 31, 2015 and 2014, respectively, will be reclassified from assets to the related debt obligations on our consolidated balance sheets.

In May 2014, the FASB issued ASU No. 2014-09, Revenue From Contracts With Customers, which outlines a comprehensive model for entities to use in accounting for revenue arising from contracts with customers. This ASU states that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” While this ASU specifically references contracts with customers, it may apply to certain other transactions such as the sale of real estate or equipment. In July 2015, the FASB approved a one year deferral of the effective date for this ASU to interim and annual reporting periods beginning after December 15, 2017. We are continuing to evaluate this guidance; however, we do not expect its adoption to have a material impact on our consolidated financial statements, as a substantial portion of our revenue consists of rental income from leasing arrangements, which are specifically excluded from this ASU.

In September 2015, the FASB issued ASU No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments, which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Instead, acquirers must recognize measurement-period adjustments during the period in which they determine the amounts, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. This update is effective for interim and

F-11

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 consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, which changes how entities measure certain equity investments and present changes in the fair value of financial liabilities measured under the fair value option that are attributable to their own credit. This update is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted subject to certain conditions. We are continuing to evaluate this guidance; however, we expect the implementation of this guidance will change our accounting for our available for sale equity investments. Currently, changes in fair value of these investments are recorded through other comprehensive income. Under this ASU, these changes will be recorded through earnings.

Note 3. Real Estate Properties

Our real estate properties, excluding those classified as held for sale, consisted of land of $781,426, buildings and improvements of $6,391,482 and FF&E of $284,032 as of December 31, 2015; and land of $681,808, buildings and improvements of $5,304,857 and FF&E of $235,695 as of December 31, 2014. Accumulated depreciation was $992,361 and $155,179 for buildings and improvements and FF&E, respectively, as of December 31, 2015; and $838,719 and $134,486 for buildings and improvements and FF&E, respectively, as of December 31, 2014.

The future minimum lease payments due to us during the current terms of our leases as of December 31, 2015, are $542,987 in 2016, $530,269 in 2017, $513,150 in 2018, $479,591 in 2019, $453,161 in 2020 and $2,980,205 thereafter.

We have accounted for the following acquisitions as business combinations unless otherwise noted.

Senior Living Community Acquisitions:

In December 2014, we entered into an agreement to acquire 38 senior living communities with 3,439 living units for an aggregate purchase price of $790,000, excluding net closing adjustments of $77 and closing costs. In May 2015, we acquired 37 of these 38 senior living communities and in September 2015 we acquired the one remaining community. We funded the acquisitions of these 38 senior living communities using cash on hand, borrowings under our revolving credit facility and the assumption of approximately $151,477 of mortgage debts with a weighted average annual interest rate of 4.57%.

Nineteen of the 38 communities are triple net leased senior living communities with 2,206 living units, and are leased to seven senior living operators. As of the date acquired, the weighted average amortization period for capitalized lease origination values was 11.5 years.  The remaining 19 acquired managed communities with 1,233 living units were acquired using TRS structures and are being managed for our account. We paid fees of $975 and terminated the pre-existing management agreements that were in place for 14 of these 19 managed communities, with 838 living units and we entered into new management agreements with Five Star to manage those 14 communities. The remaining five managed communities, with 395 living units, continue to be managed by a third party senior living manager in place at the time of our acquisition of these communities. As of December 31, 2015, we own 65 managed senior living communities that are managed by Five Star and one third party senior living manager.

In September 2015, we acquired one triple net leased senior living community with 84 living units for a purchase price of $18,250, excluding closing costs. We funded the acquisition of this community using cash on hand and borrowings under our revolving credit facility. This community is leased to a privately owned third party senior living operator. This acquisition was accounted for as an acquisition of assets.

In May 2015, we acquired one senior living community with 40 private pay independent living units for a purchase price of approximately $9,750, excluding closing costs. Pursuant to the purchase agreement, $1,000 of the purchase price has been withheld until the seller satisfies various conditions. We anticipate these conditions will be satisfied and therefore have recorded the withheld $1,000 as a liability as of December 31, 2015. This liability is included in other liabilities in our consolidated balance sheets. This senior living community is adjacent to another community that we own which is

F-12

managed by Five Star; and the operations of this community and the community we previously owned are now conducted as a single integrated community under one management agreement.

In February 2015, we acquired a land parcel adjacent to a senior living community we lease to Five Star for $490. This property was added to the lease for that senior living community and Five Star’s annual minimum rent payable to us increased by $39 as a result.

During 2014, we acquired two senior living communities with a total of 228 living units for total purchase prices of approximately $47,430, excluding closing costs, and entered into management agreements with Five Star to manage these communities.

The table below represents the purchase price allocations (including net closing adjustments) of the senior living community acquisitions described above.

(1) Cash paid plus assumed debt, if any, excludes closing costs. The allocation of the purchase price of certain of our 2015 acquisitions shown above is based upon preliminary estimates of the fair value of assets acquired and liabilities assumed. Therefore, amounts preliminarily allocated to assets acquired and liabilities assumed could change significantly from those used in these consolidated financial statements.

(2) This senior living community is adjacent to another community that we own which is managed by Five Star. The operations of this community and the community we previously owned are now conducted as a single integrated community under one management agreement.

See Note 5 for further information regarding the arrangements we have with Five Star.

MOB Acquisitions:

In January 2015, we acquired 23 properties (23 buildings) leased to MOBs for an aggregate purchase price of $539,000, excluding net credits received of $7,377 related to debt assumption costs and outstanding tenant improvement allowances and excluding closing costs. These MOBs include approximately 2,170,000 leasable square feet. We funded this acquisition using cash on hand, borrowings under our revolving credit facility and the assumption of $29,955 of mortgage debts with a weighted average annual interest rate of 4.73%. As of the date acquired, the weighted average amortization periods for capitalized above market lease values, lease origination costs and capitalized below market lease values were 9.7 years, 9.5 years and 11.2 years, respectively. These 23 properties were purchased from Select Income

F-13

REIT, or SIR, in connection with the acquisition by SIR of Cole Corporate Income Trust, Inc., or CCIT. See Note 5 for further information regarding this transaction.

During 2014, we acquired two MOBs (three buildings) with a total of 1,776,277 square feet for total purchase prices of approximately $1,162,584 including the assumption of approximately $15,630 of mortgage debt and excluding closing costs.

The table below represents the purchase price allocations (including net closing adjustments) of the MOB acquisitions described above.

(1) Cash paid plus assumed debt, if any, excludes closing costs.

In January 2016, we entered into an agreement to acquire one senior living community located in Georgia with 38 private pay units for a purchase price of approximately $8,400, excluding closing costs. We expect to acquire this community using a TRS structure and to have Five Star manage this community. This acquisition is subject to various conditions; accordingly we can provide no assurance that we will purchase this property, that the acquisition or related expected management agreement with Five Star will not be delayed or that the terms will not change.

In February 2016, we acquired one MOB (three buildings) in Minnesota with approximately 128,000 square feet for a purchase price of approximately $22,700, excluding closing costs.

At December 31, 2015, we had recorded intangible lease assets of $779,761, including $48,048 of capitalized above market lease values and $731,713 of the value of in place leases. At December 31, 2014, we had recorded intangible assets of $577,177, including $47,107 of capitalized above market lease values and $530,070 of the value of in place leases. We had recorded intangible lease obligations of $139,346 and $138,469 at December 31, 2015 and 2014, respectively. Accumulated amortization of capitalized above market lease values was $26,828 and $22,749 at December 31, 2015 and 2014, respectively. At December 31, 2015, the remaining weighted average amortization period of capitalized above market lease values is approximately 5.3 years. Accumulated amortization of capitalized below market lease values was $23,819 and $15,643 at December 31, 2015 and 2014, respectively. At December 31, 2015, the remaining weighted average amortization period of intangible lease obligations is approximately 12.5 years. Accumulated amortization of the value of in place leases exclusive of the value of above and below market in place leases was $148,647 and $81,640 at December 31, 2015 and 2014, respectively. At December 31, 2015, the remaining weighted average amortization period of the value of in place leases exclusive of the value of above and below market in place leases is approximately 10.6 years. We expect to recognize net future amortization of these intangible lease assets and liabilities in the amounts of approximately $76,793 in 2016, $72,769 in 2017, $44,196 in 2018, $38,982 in 2019, $36,571 in 2020 and $219,611 thereafter.

Dispositions:

In February 2015, we sold one vacant senior living community for $250, excluding closing costs. In July 2015, we sold one senior living community for $155, excluding closing costs. In August 2015, we sold one senior living community for $850, excluding closing costs. In December 2015, we sold one senior living community for $21, excluding closing costs.

F-14

In April 2015, we sold one MOB (four buildings) previously included in discontinued operations for $1,500, excluding closing costs.

In January, June, and October 2014, we sold six senior living communities which were previously classified as held for sale, for combined sales prices of $15,650, excluding closing costs, and recognized an aggregate gain on sale on these properties of approximately $5,452.  In April, June, and September 2014, we sold three MOBs (3 buildings) that were previously included in discontinued operations for combined sales prices of $11,675, excluding closing costs.

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. 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.

During 2015, we recorded net impairment charges of $796 to adjust the carrying values of one MOB (four buildings) and three senior living communities to their aggregate estimated net sale price. We classify all properties as held for sale in our consolidated balance sheets that meet the applicable criteria for that treatment as set forth in the Property, Plant and Equipment Topic of the Codification.

As of December 31, 2015, we had one senior living community with 140 living units and one vacant land parcel categorized as held for sale.  The real estate assets of this senior living community and land parcel are included in other assets in our consolidated balance sheets and have a net book value (after impairment) of approximately $5,356 at December 31, 2015.

As of December 31, 2014, we had four senior living communities with 312 living units and one MOB (four buildings) with 323,541 square feet categorized as properties held for sale. During 2014, we recorded net impairment charges of $4,377 to adjust the carrying value of four MOBs (seven buildings) to their aggregate estimated net sale price. These properties have all been sold as of December 31, 2015, as described above.

Results of operations for properties sold or held for sale are included in discontinued operations in our consolidated statements of comprehensive income once the criteria for discontinued operations in the Presentation of Financial Statements Topic of the Codification are met. The senior living communities which we are or were offering for sale as of the applicable periods do not meet the criteria for discontinued operations. Summarized income statement information for the four MOBs (seven buildings) that met the criteria for discontinued operations is included in discontinued operations as follows:

	For the year ended December 31,
	2015		2014		2013
Rental income	$	56	$	3,949	$	9,451

On June 5, 2015, we issued 2,345,000 of our common shares in connection with our acquisition of an interest in RMR Inc., as further described in Note 5.

F-16

On September 24, 2015, we purchased an aggregate of 13,113 of our common shares for $16.19 per share, the closing price of our common shares on the NYSE on that day, from certain of our officers and other employees of RMR LLC in satisfaction of tax withholding and payment obligations in connection with the vesting of awards of restricted common shares.

During the year ended December 31, 2015, we issued 81,557 of our common shares to RMR LLC as part of the business management fees payable by us under our business management agreement. See Note 5 for further information regarding this agreement.

Note 5. Related Person Transactions

We have adopted written Governance Guidelines that describe the consideration and approval of related person transactions. Under these Governance Guidelines, we may not enter into a transaction in which any Trustee or executive officer, any member of the immediate family of any Trustee or executive officer or other related person, has or will have a direct or indirect material interest unless that transaction has been disclosed or made known to our Board of Trustees and our Board of Trustees reviews and approves or ratifies the transaction by the affirmative vote of a majority of the disinterested Trustees, even if the disinterested Trustees constitute less than a quorum. If there are no disinterested Trustees, the transaction must be reviewed, authorized and approved or ratified by both (i) the affirmative vote of a majority of our Board of Trustees and (ii) the affirmative vote of a majority of our Independent Trustees. In determining whether to approve or ratify a transaction, our Board of Trustees, or disinterested Trustees or Independent Trustees, as the case may be, also act in accordance with any applicable provisions of our declaration of trust and bylaws, consider all of the relevant facts and circumstances and approve only those transactions that they determine are fair and reasonable to us. All related person transactions described below were reviewed and approved or ratified by a majority of the disinterested Trustees or otherwise in accordance with our policies, declaration of trust and bylaws, each as described above. In the case of transactions with us by employees of RMR Inc. and its subsidiaries who are subject to our Code of Business Conduct and Ethics, but who are not Trustees or executive officers of us, the employee must seek approval from an executive officer who has no interest in the matter for which approval is being requested. Copies of our Governance Guidelines and Code of Business Conduct and Ethics are available on our website, www.snhreit.com.

Five Star. Five Star was formerly our 100% owned subsidiary. Five Star is our largest tenant, we are Five Star's largest stockholder and Five Star manages certain senior living communities for us. In 2001, we distributed substantially all of Five Star's then outstanding shares of common stock to our shareholders. As of December 31, 2015, we owned 4,235,000 shares of common stock of Five Star, or approximately 8.6% of Five Star's outstanding shares of common stock.

One of our Managing Trustees, Mr. Barry Portnoy, is a Managing Director of Five Star. RMR LLC provides management services to both us and Five Star. Five Star's president and chief executive officer is an officer of RMR LLC and Five Star’s treasurer and chief financial officer is an officer of RMR LLC and was formerly our Treasurer and Chief Financial Officer from 2007 through 2015. Accordingly, the transactions between us and Five Star entered into after Five Star became a separate public company and that are described herein were approved by our Independent Trustees and Five Star's independent directors who are not trustees or directors of the other company. In order to affect the spin-off of Five Star and to govern relations after the spin-off, Five Star entered into agreements with us and others, including RMR LLC.

F-17

Since then, Five Star has entered into various leases, management agreements and other agreements with us that include provisions that confirm and modify these undertakings. Among other matters, these agreements provide that:

· so long as we remain a REIT, Five Star may not waive the share ownership restrictions in its charter on the ability of any person or group to acquire more than 9.8% of any class of Five Star’s equity shares without our consent;

· so long as Five Star is our tenant or manager, Five Star will not permit nor take any action that, in our reasonable judgment, might jeopardize our tax status as a REIT;

· we have the option to cancel all of Five Star's rights under the leases and management agreements it has with us upon the acquisition by a person or group of more than 9.8% of Five Star's voting stock and upon other change in control events affecting Five Star, as defined in those documents, including the adoption of any shareholder proposal (other than a precatory proposal) or the election to Five Star's board of directors of any individual if such proposal or individual was not approved, nominated or appointed, as the case may be, by vote of a majority of Five Star's directors in office immediately prior to the making of such proposal or the nomination or appointment of such individual;

· the resolution of disputes arising from Five Star's leases and other agreements with us may be resolved by binding arbitration; and

· so long as Five Star is a tenant of ours or manager for us or so long as Five Star has a business management agreement with RMR LLC, Five Star will not acquire or finance any real estate of a type then owned or financed by us or any company managed by RMR LLC without first giving us or such company managed by RMR LLC, as applicable, the opportunity to acquire or finance that real estate.

Senior Living Communities we lease to Five Star. As of December 31, 2015, we leased 177 senior living communities to Five Star. Under Five Star's leases with us, Five Star pays us rent consisting of minimum annual rent amounts plus percentage rent based on increases in gross revenues at certain properties. Five Star's total minimum annual rent payable to us as of December 31, 2015 was $191,927, excluding percentage rent. We recognized total rental income from Five Star of $196,919,  $196,269 and $203,724 for the years ended December 31, 2015, 2014 and 2013, respectively. As of December 31, 2015 and 2014, our rents receivable from Five Star were $17,466 and $17,310, respectively, and those amounts are included in due from affiliate in our consolidated balance sheets. We determine percentage rent due under our Five Star leases annually and recognize it at year end when all contingencies are met. During the years ended December 31, 2015, 2014 and 2013, pursuant to the terms of our leases with Five Star, we purchased $21,444,  $25,804 and $27,208, respectively, of improvements to properties leased to Five Star, and, as a result, the annual rent payable to us by Five Star increased by approximately $1,734,  $2,066 and $2,177, respectively.

In June 2013, we and Five Star agreed to offer for sale 11 senior living communities we then leased to Five Star. Five Star's rent payable to us was reduced as these sales occurred pursuant to terms set in our leases with Five Star. These 11 senior living communities had all been sold as of December 31, 2015, as follows:

· In August 2013, we and Five Star sold a skilled nursing facility, or SNF, located in Missouri with 112 SNF units, for a sale price of $2,550; and, as a result of this sale, Five Star's annual minimum rent payable to us decreased by $255 in accordance with the terms of the applicable lease.

· In January 2014, we and Five Star sold a senior living community located in Texas with 36 assisted living units, for a sale price of $2,400; and, as a result of this sale, Five Star's annual minimum rent payable to us decreased by $210 in accordance with the terms of the applicable lease.

· In June 2014, we and Five Star sold two senior living communities located in Wisconsin with 156 SNF units for a sale price of $4,500; and, as result of this sale, Five Star’s annual minimum rent payable to us decreased by $452 in accordance with the terms of the applicable lease.

F-18

· In October 2014, we and Five Star sold a senior living community located in Virginia with 70 assisted living units for a sale price of $2,850; and, as a result of this sale, Five Star’s annual minimum rent payable to us decreased by $285 in accordance with the terms of the applicable lease.

· Also in October 2014, we and Five Star sold two senior living communities located in Arizona with 177 assisted living and SNF units for a sale price of $5,900; and, as a result of this sale, Five Star’s annual minimum rent payable to us decreased by $590 in accordance with the terms of the applicable lease.

· In February 2015, we and Five Star sold a senior living community located in Pennsylvania with 120 assisted living units for a sale price of $250; and, as 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.

· In July 2015, we and Five Star sold a senior living community located in Iowa with 12 SNF units for a sale price of $155; and, as a result of this sale, Five Star’s annual minimum rent payable to us decreased by $16 in accordance with the terms of the applicable lease.

· In August 2015, we and Five Star sold a senior living community located in Wisconsin with 63 SNF units for $850; and, as a result of this sale, Five Star’s annual minimum rent payable to us decreased by $85 in accordance with the terms of the applicable lease.

· In December 2015, we and Five Star sold a property that was previously a senior living community for a sale price of $21; and, as a result of this sale, Five Star’s annual minimum rent payable to us decreased by $2 in accordance with the terms of the applicable lease.

In December 2013, pursuant to an asset purchase agreement, or Purchase Agreement, we sold two rehabilitation hospitals and certain related assets to unrelated parties for a sales price of approximately $90,000, and Five Star transferred the operations of the two hospitals and several in-patient and out-patient clinics affiliated with those hospitals, to those third parties. Each hospital was previously leased by us to Five Star under Lease No. 2 and was operated by Five Star. Pursuant to an amendment to Lease No. 2 that we entered into in September 2013 in connection with our agreement to sell these rehabilitation hospitals and Five Star’s agreement to transfer its related hospital operations, Lease No. 2 terminated with respect to the rehabilitation hospitals and the annual rent paid to us by Five Star under Lease No. 2 was reduced by $9,500 upon the closing of the sale of the hospitals. The lease amendment also provides for an allocation of indemnification obligations under the Purchase Agreement between us and Five Star.

In July 2014, we and Five Star entered into the Fifth Amendment to the Amended and Restated Master Lease Agreement (Lease No. 4) pursuant to which Five Star exercised the first of its existing lease extension options under Lease No. 4, extending the term from April 30, 2017 to April 30, 2032, and we granted Five Star a third option for Five Star to extend the term of Lease No. 4 from May 1, 2047 to April 30, 2062.

In February 2015, we acquired a land parcel adjacent to a senior living community we lease to Five Star for $490. This property was added to the lease for that senior living community and Five Star’s annual minimum rent payable to us increased by $39 as a result.

Our Senior Living Communities Managed by Five Star. As of December 31, 2015, 2014 and 2013, Five Star managed 60,  46 and 44 senior living communities for our account, respectively. We lease our senior living communities that are managed by Five Star that include assisted living units or skilled nursing facilities to our TRSs, and Five Star manages these communities pursuant to long term management agreements on substantially similar terms. With the exception of the management agreement for the senior living community in New York described below, the management agreements for the communities Five Star manages for our account provide Five Star with a management fee equal to 3% of the gross revenues realized at the communities, plus reimbursement for Five Star's direct costs and expenses related to the communities and an incentive fee equal to 35% of the annual net operating income of the communities after we realize an annual return equal to 8% of our invested capital. The management agreements generally expire on December 31, 2031, 2032, 2033 or 2035, and are subject to automatic renewal for two consecutive 15 year terms, unless earlier terminated or timely notice of nonrenewal is delivered. The management agreements generally provide that we and Five Star each have

F-19

the option to terminate the agreements upon the acquisition by a person or group of more than 9.8% of the other's voting stock and upon other change in control events affecting the other party, as defined in those documents, including the adoption of any shareholder proposal (other than a precatory proposal) or the election to the board of directors or board of trustees of any individual if such proposal or individual was not approved, nominated or appointed, as the case may be, by vote of a majority of the board of directors or board of trustees in office immediately prior to the making of such proposal or the nomination or appointment of such individual.

In connection with the management agreements, we and Five Star have entered into four combination agreements, or pooling agreements, three of which combine our management agreements for communities that include assisted living units, or the AL Pooling Agreements, and the fourth of which combines our management agreements for communities consisting only of independent living units, or the IL Pooling Agreement. The management agreements that are included in each of our pooling agreements are on substantially similar terms. Our first AL Pooling Agreement, which we entered into in May 2011, includes 20 identified communities and our second AL Pooling Agreement, which we entered into in October 2012, includes 19 identified communities. We and Five Star entered into the third AL Pooling Agreement in November 2013 and that pooling agreement currently includes the management agreements for three identified communities. We entered into the IL Pooling Agreement in August 2012 and that agreement currently includes management agreements for two communities that have only independent living units. The senior living community in New York, one senior living community in California described below and the 14 senior living communities we acquired in May 2015 as described below and in Note 3 that Five Star manages for our account are not included in any of our pooling agreements. Each of the AL Pooling Agreements and the IL Pooling Agreement aggregates the determination of fees and expenses of the various communities that are subject to such pooling agreement, including determinations of our return on our invested capital and Five Star's incentive fees. Under each of the pooling agreements, we have the right, after the period of time specified in the agreement has elapsed and subject to Five Star's cure rights, to terminate all, but not less than all, of the management agreements that are subject to the agreement if we do not receive our minimum return in each of three consecutive years. In addition, under each of the pooling agreements, Five Star has a limited right to require the sale of underperforming communities. Also, under each of the pooling agreements, any nonrenewal notice given by Five Star with respect to a community is deemed a nonrenewal with respect to all the communities that are the subject of the agreement. We incurred management fees of $10,728,  $9,765 and $9,229 for the years ended December 31, 2015, 2014 and 2013, respectively, with respect to the communities Five Star manages. These amounts are included in property operating expenses in our consolidated statements of comprehensive income.

In July 2014, we entered into an agreement with Five Star, pursuant to which the management agreement for our assisted living community known as Villa Valencia, which is located in California, was removed from the second AL Pooling Agreement as of July 1, 2014. We expect that the management agreement affecting the Villa Valencia community will not be included in any pooling agreement until after extensive renovations planned at that community are completed.

In July 2014, we entered into an amendment to our management agreements with Five Star that include assisted living communities to (i) extend the term of each of the management agreements between us and Five Star for Villa Valencia and the 19 assisted living communities currently included in the second AL Pooling Agreement from December 31, 2031 to December 31, 2033 and (ii) extend the term of the management agreement between us and Five Star for the senior living community that was then and continues to be included in the third AL Pooling Agreement, from December 31, 2031 to December 31, 2035. In July 2014, we also entered into an amendment to our management agreements with Five Star that include only independent living communities to extend the term of the management agreements between us and Five Star for two independent living communities from December 31, 2031 to December 31, 2032. All of our management agreements that are currently included in the third AL Pooling Agreement expire on December 31, 2035.

In December 2014, we acquired two senior living communities in Wisconsin for a total of $47,430, excluding closing costs. Five Star manages these communities for our account pursuant to separate long term management agreements for communities that include assisted living units and these two management agreements are included in the third AL Pooling Agreement.

In connection with our acquisition of 37 senior living communities in May 2015 described in Note 3, we terminated the pre-existing management agreements for 14 of these communities, with 838 living units, and entered into 14 separate management agreements with Five Star for it to manage these communities for our account.

F-20

In May 2015, we acquired one senior living community in Georgia with 40 private pay independent living units for approximately $9,750, excluding closing costs, using a TRS structure. This senior living community is adjacent to another community that we own which is managed by Five Star. The operations of this community and the community we previously owned are now conducted as a single integrated community under one management agreement.

We expect that we may amend certain provisions of our management agreements with Five Star as circumstances affecting the managed communities change and that we may enter into additional management arrangements with Five Star for senior living communities that we may acquire in the future.

We own a senior living community in New York with 310 living units, a portion of which is managed by Five Star pursuant to a long term management agreement with us with respect to the senior living units at this community that are not subject to the requirements of New York healthcare licensing laws. The terms of this management agreement are substantially consistent with the terms of our other management agreements with Five Star for communities that include assisted living units, except the management fee payable to Five Star is equal to 5% of the gross revenues realized at that portion of the community and there is no incentive fee payable by us to Five Star. This management agreement expires on December 31, 2031. In order to accommodate certain requirements of New York healthcare licensing laws, one of our TRSs subleases the portion of this community that is subject to those requirements to an entity, D&R Yonkers LLC, which is owned by our President and Chief Operating Officer and Five Star’s chief financial officer and treasurer. Five Star manages this portion of the community pursuant to a long term management agreement with D&R Yonkers LLC. Under the sublease agreement, the annual rent at December 31, 2015 is $3,098 but D&R Yonkers LLC is obligated to pay rent only from available revenues generated by the subleased community. In 2015, 2014 and 2013, D&R Yonkers LLC incurred $3,038,  $2,949 and $2,863, respectively, in rent. Our TRS is obligated to advance any rent shortfalls to D&R Yonkers LLC, and D&R Yonkers LLC is obligated to repay one of our TRSs only from available revenues generated by the subleased community. Pursuant to the management agreement between D&R Yonkers LLC and Five Star, D&R Yonkers LLC pays Five Star a management fee equal to 3% of the gross revenues realized at that portion of the community and there is no incentive fee payable by D&R Yonkers LLC to Five Star. D&R Yonkers LLC's management agreement with Five Star expires on August 31, 2017, and is subject to renewal for nine consecutive five year terms, unless earlier terminated or timely notice of nonrenewal is delivered. Further, we have entered into an indemnification agreement with the owners of D&R Yonkers LLC, pursuant to which we have agreed to indemnify them for costs, losses and expenses they may sustain by reason of being a member, director or officer of D&R Yonkers LLC or in connection with any costs, losses or expenses under our TRS's sublease with D&R Yonkers LLC or the management agreement between D&R Yonkers LLC and Five Star.

Our Manager, RMR LLC. We have no employees. The personnel and various services we require to operate our business are provided to us by RMR LLC. We have two agreements with RMR LLC to provide management services to us: (i) a business management agreement, which relates to our business generally, and (ii) a property management agreement, which relates to the property level operations of our MOBs, both of which are described below in this Note under “—Management Agreements with RMR LLC.”

One of our Managing Trustees, Mr. Barry Portnoy, is a Managing Director, officer and controlling shareholder (through ABP Trust) of RMR Inc. and an officer of RMR LLC. Our other Managing Trustee, Mr. Adam Portnoy, is a Managing Director, President, Chief Executive Officer and controlling shareholder (through ABP Trust) of RMR Inc. and an officer of RMR LLC. ABP Trust is owned by Messrs. Barry and Adam Portnoy. Messrs. Barry and Adam Portnoy also own class A membership units of RMR LLC through their ownership of ABP Trust. Each of our executive officers is also an officer of RMR LLC. Our Independent Trustees also serve as independent directors or independent trustees of other companies to which RMR LLC or its affiliates provide management services. Mr. Barry Portnoy serves as a director, managing director, trustee or managing trustee of all of these companies and Mr. Adam Portnoy serves as a director, trustee or managing trustee of a majority of those companies. In addition, officers of RMR LLC and RMR Inc. serve as our officers and officers of other companies to which RMR LLC or its affiliates provide management services. 

Acquisition of Interest in our Manager. On June 5, 2015, we and three other REITs to which RMR LLC provides management services – Government Properties Income Trust, or GOV, Hospitality Properties Trust, or HPT, and SIR, and collectively with GOV and HPT, the Other REITs – participated in a transaction, or the Up-C Transaction, by which we and the Other REITs each acquired class A common stock of RMR Inc.

F-21

The Up-C Transaction was completed pursuant to a transaction agreement by and among us, our manager, RMR LLC, its then sole member, ABP Trust, and RMR Inc. and similar transaction agreements that each Other REIT entered into with RMR LLC, ABP Trust and RMR Inc. Pursuant to these transaction agreements: we contributed to RMR Inc. 2,345,000 of our common shares and $13,967 in cash; GOV contributed to RMR Inc. 700,000 of its common shares and $3,917 in cash; HPT contributed to RMR Inc. 1,490,000 of its common shares and $12,622 in cash; SIR contributed to RMR Inc. 880,000 of its common shares and $15,880 in cash; ABP Trust contributed to RMR Inc. $11,520 in cash, which RMR Inc. contributed to RMR LLC; RMR LLC issued 1,000,000 of its class B membership units to RMR Inc.; RMR Inc. issued 5,272,787 shares of its class A common stock to us, 1,541,201 shares of its class A common stock to GOV, 5,019,121 shares of its class A common stock to HPT, 3,166,891 shares of its class A common stock to SIR and 1,000,000 shares of its class B-1 common stock and 15,000,000 shares of its class B-2 common stock to ABP Trust; ABP Trust delivered 15,000,000 of the 30,000,000 class A membership units of RMR LLC which ABP Trust then owned to RMR Inc.; and RMR Inc. delivered to ABP Trust our common shares, the common shares of the Other REITs and the cash which had been contributed by us and the Other REITs to RMR Inc.

The class A common stock and class B-1 common stock of RMR Inc. share ratably as a single class in dividends and other distributions of RMR Inc. when and if declared by the board of directors of RMR Inc. and have the same rights in a liquidation of RMR Inc. The class B-1 common stock of RMR Inc. is convertible into class A common stock of RMR Inc. on a 1:1 basis. The class A common stock of RMR Inc. has one vote per share. The class B-1 common stock of RMR Inc. has 10 votes per share. The class B-2 common stock of RMR Inc. has no economic interest in RMR Inc., but has 10 votes per share and is paired with the class A membership units of RMR LLC owned by ABP Trust. Upon request by ABP Trust, RMR LLC is required to redeem the class A membership units of RMR LLC owned by ABP Trust for class A common stock of RMR Inc. on a 1:1 basis, or if RMR Inc. elects, for cash. Under the governing documents of RMR Inc., upon the redemption of a class A membership unit of RMR LLC, the share of class B-2 common stock of RMR Inc. “paired” with the class A membership unit being redeemed is cancelled for no additional consideration.

As part of the Up-C Transaction and concurrently with entering the transaction agreements, on June 5, 2015:

· We entered into an amended and restated business management agreement with RMR LLC and an amended and restated property management agreement with RMR LLC. The amendments made by these agreements are described below in this Note under “—Management Agreements with RMR LLC.” Each Other REIT also entered amended and restated business and property management agreements with RMR LLC, which made similar amendments to their management agreements with RMR LLC.

· We entered into a registration rights agreement with RMR Inc. covering the class A common stock of RMR Inc. that we received in the Up-C Transaction, pursuant to which we received demand and piggyback registration rights, subject to certain limitations. Each Other REIT entered into a similar registration rights agreement with RMR Inc.

· We entered into a lock up and registration rights agreement with ABP Trust and Messrs. Barry and Adam Portnoy pursuant to which ABP Trust and Messrs. Barry and Adam Portnoy agreed not to transfer the 2,345,000 of our common shares ABP Trust received in the Up-C Transaction for a period of 10 years and we granted them certain registration rights, subject to certain limited exceptions. Each Other REIT also entered into a similar lock up and registration rights agreement with ABP Trust and Messrs. Barry and Adam Portnoy.

As a result of the Up-C Transaction: RMR LLC became a subsidiary of RMR Inc.; RMR Inc. became the managing member of RMR LLC; through our ownership of class A common stock of RMR Inc., we became a holder of an indirect economic interest in RMR LLC; and through their ownership of class A common stock of RMR Inc., GOV, HPT and SIR also became holders of indirect economic interests in RMR LLC. Through its ownership of class B-1 common stock of RMR Inc., class B-2 common stock of RMR Inc. and class A membership units of RMR LLC. ABP Trust holds, directly and indirectly has a 51.6% economic interest in RMR LLC and controls 91.4% of the voting power of outstanding capital stock of RMR Inc.

Pursuant to the transaction agreements, on December 14, 2015 we distributed 2,635,379 shares of class A common

F-22

stock of RMR Inc. to our shareholders as a special distribution, which represented approximately half of the shares of class A common stock of RMR Inc. we received in the Up-C Transaction; each Other REIT also distributed approximately half of the shares of class A common stock of RMR Inc. they received in the Up-C Transaction to their respective shareholders. RMR Inc. facilitated this distribution by filing a registration statement with the SEC to register the shares of class A common stock of RMR Inc. being distributed and by listing those shares on the NASDAQ Stock Market LLC. Following this distribution, we currently hold 2,637,408 shares of class A common stock of RMR Inc. and GOV, HPT and SIR currently hold 1,214,225,  2,503,777 and 1,586,836 shares of class A common stock of RMR Inc., respectively. In connection with this distribution, we recognized a non-cash loss of $38,437 in the fourth quarter of 2015 as a result of the closing price of RMR Inc.’s class A common stock being lower than our carrying amount per RMR Inc. share on the distribution date.

On December 15, 2015, RMR Inc. paid a cash dividend to holders of its class A common stock and class B-1 common stock as of November 25, 2015 of $0.5260 per share related to the period from and including June 5, 2015 up to but not including December 14, 2015. As a result of our ownership of class A common stock of RMR Inc., we received a cash dividend of approximately $2,773 from RMR Inc.

The transactions contemplated by the transaction agreement and the terms thereof were negotiated and reviewed by a Joint Special Committee comprised solely of our Independent Trustees and the independent trustees of the Other REITs, or the Joint Special Committee, and were separately approved and adopted by our Independent Trustee who did not serve as an independent trustee of any of the Other REITs, by a Special Committee of our Board of Trustees, comprised solely of our Independent Trustees, or our Special Committee, and by our Board of Trustees. Morgan Stanley & Co. LLC acted as financial advisor to the Joint Special Committee and Centerview Partners LLC acted as financial advisor to our Special Committee.

Accounting for Investment in RMR Inc. We concluded, for accounting purposes, that the cash and share consideration of $60,700 we paid for our investment in 5,272,787 shares of class A common stock of RMR Inc. represented a discount to the fair value of these shares. We initially accounted for this investment under the cost method of accounting and recorded this investment at its estimated fair value of $136,278 as of June 5, 2015, using Level 3 inputs as defined in the fair value hierarchy under GAAP. As a result, we recorded a liability for the amount by which the estimated fair value exceeded the price we paid for these shares and we are amortizing this amount as described below. As of December 31, 2015, the unamortized balance of this liability was $77,850. The liability for our investment in class A common stock of RMR Inc. is included in other liabilities in our consolidated balance sheet and is being amortized on a straight line basis through December 31, 2035, the 20 year life of the business and property management agreements with RMR LLC entered on June 5, 2015 as an allocated reduction to business management fees and property management fees, which are included in general and administrative and other operating expenses, respectively, in our consolidated statements of comprehensive income. Amortization of this liability, which is included in general and administrative expense and property operating expenses for the year ending December 31, 2015 totaled $2,145.

Management Agreements with RMR LLC.For 2013, our business management agreement provided for the base business management fee to be paid to RMR LLC at an annual rate equal to the sum of (a) 0.5% of the historical cost of the real estate assets acquired from a REIT to which RMR LLC provided business management or property services, or the Transferred Assets, plus (b) 0.7% of the historical cost of our other real estate investments excluding the Transferred Assets, up to the first $250,000 of such investments, and 0.5% thereafter. In addition, for 2013, our business management agreement also provided for RMR LLC to be paid an incentive fee equal to 15% of the product of (i) the weighted average of our common shares outstanding on a fully diluted basis during a fiscal year and (ii) the excess, if any, of the Normalized FFO Per Share, as defined in that business management agreement, for such fiscal year over the Normalized FFO Per Share for the preceding fiscal year. This incentive fee was payable in common shares and it was subject to a cap on the value of the incentive fee being no greater than $0.02 per share of our total shares outstanding.

On December 23, 2013, we and RMR LLC amended and restated our business management agreement, effective with respect to services performed on or after January 1, 2014. After these amendments, our business management agreement provided that:

F-23

· Revised Base Management Fee. The annual amount of the base management fee to be paid to RMR LLC by us for each applicable period is equal to the lesser of:

o the sum of (a) 0.5% of the average of the aggregate book value of our real estate assets owned by us or our subsidiaries as of October 12, 1999, or the Transferred Assets, plus (b) 0.7% of the average historical cost of our real estate investments excluding the Transferred Assets up to $250,000, plus (c) 0.5% of the average historical cost of our real estate investments excluding the Transferred Assets exceeding $250,000; and

o the sum of (a) 0.7% of the average closing price per share of our common shares on the New York Stock Exchange, or NYSE, during such period, multiplied by the average number of our common shares outstanding during such period, plus the daily weighted average of the aggregate liquidation preference of each class of our preferred shares outstanding during such period, plus the daily weighted average of the aggregate principal amount of our consolidated indebtedness during such period, or, together, our Average Market Capitalization, up to $250,000, plus (b) 0.5% of our Average Market Capitalization exceeding $250,000.

The average aggregate historical cost of our real estate investments includes our consolidated assets invested, directly or indirectly, in equity interests in or loans secured by real estate and personal property owned in connection with such real estate (including acquisition related costs and costs which may be allocated to intangibles or are unallocated), all before reserves for depreciation, amortization, impairment charges or bad debts or other similar noncash reserves.

· Revised Incentive Fee. The incentive fee which may be earned by RMR LLC for an annual period is an amount, subject to a cap based on the value of our outstanding common shares, equal to 12% of the product of (a) our equity market capitalization on the last trading day on the year immediately prior to the relevant measurement period and (b) the amount (expressed as a percentage) by which the total returns per share realized by the holders of our common shares (i.e., share price appreciation plus dividends) exceeds the total shareholder return of the SNL REIT Healthcare Index (in each case subject to certain adjustments) for the relevant measurement period. The measurement periods are generally three-year periods ending with the year for which the incentive fee is being calculated, with shorter periods applicable in the case of the calculation of the incentive fee for 2014 (one year) and 2015 (two years). The terms of the revised incentive fee were developed by our Compensation Committee, which is comprised solely of Independent Trustees, in consultation with FTI Consulting, Inc., a nationally recognized compensation consultant experienced in REIT compensation programs.

· Partial Payment in Common Shares. The base management fee would be paid monthly to RMR LLC, 90% in cash and 10% in our common shares, which are fully-vested when issued. The number of our common shares to be issued in payment of the base management fee for each month would equal the value of 10% of the total base management fee for that month divided by the average daily closing price of our common shares during that month. The incentive fee would be payable in our common shares, with one-third of our common shares issued in payment of an incentive fee vested on the date of issuance, and the remaining two-thirds vesting thereafter in two equal annual installments. All common shares issued in payment of the incentive fee would be fully vested upon termination of the business management agreement, subject to certain exceptions. In addition, RMR LLC would, in certain circumstances, be required to return to us or forfeit some or all of the common shares paid or payable to it in payment of the incentive management fee. RMR LLC and certain eligible transferees of our common shares issued in payment of the base management fee or incentive fee would be entitled to demand registration rights, exercisable not more frequently than twice per year, and to "piggy-back" registration rights, with certain expenses to be paid by us. We and applicable selling shareholders also indemnify each other (and their officers, trustees, directors and controlling persons) against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or the Securities Act, in connection with any such registration.

F-24

· Elimination of Right of First Offer. The right of first offer was eliminated. This right of first offer had required that with certain exceptions, if we determined to offer for sale or other disposition any real property that, at such time, is of a type within the investment focus of another REIT to which RMR LLC provides management services, we would first offer that property for purchase or disposition to that REIT and negotiate in good faith for such purchase or disposition. Under our business management agreement, we acknowledge that RMR LLC may engage in other activities or businesses and act as the manager to any other person or entity (including other REITs) even though such person or entity has investment policies and objectives similar to ours and we are not entitled to preferential treatment in receiving information, recommendations and other services from RMR LLC.

On May 9, 2014, we and RMR LLC entered into the following amendments to our business management agreement and property management agreement:

· Revised RMR LLC Termination Right. RMR LLC’s right to terminate the business management and property management agreements was changed to 120 days’ written notice from the previous 60 days’ written notice for the business management agreement and five business days’ notice if we underwent a change of control for the property management agreement.

· RMR LLC Termination Fee. We agreed that if we terminate or elect not to renew the business management agreement other than for cause, as defined, we would pay RMR LLC a termination fee equal to 2.75 times the sum of the annual base management fee and the annual internal audit services expense, which amounts are based on averages during the 24 consecutive calendar months prior to the date of notice of nonrenewal or termination. In addition, we agreed that if we terminate or elect not to renew the property management agreement other than for cause, as defined, within 12 months prior to or following our giving notice of termination or non-renewal of the business management agreement other than for cause, we would pay RMR LLC a termination fee equal to 12 times the average monthly property management fee for the six months prior to the effective date of the nonrenewal or termination.

· Transitional Services. RMR LLC agreed to provide certain transition services to us for 120 days following an applicable termination by us or notice of termination by RMR LLC, including cooperating with us and using commercially reasonable efforts to facilitate the orderly transfer of the management and real estate investment services provided under the business management agreement and to facilitate the orderly transfer of management of the managed properties, as applicable.

As part of the Up-C Transaction described above, on June 5, 2015, we and RMR LLC amended and restated our business management agreement and our property management agreement. As a result of these amendments, effective as of June 5, 2015:

· Extended Term. Our management agreements have terms that end on December 31, 2036, and automatically extend on December 31st of each year for an additional year, so that the terms of the agreements thereafter end on the 20th anniversary of the date of the extension.

· Payment of Fees in Cash. All base management and incentive fees under our management agreements are payable in cash.

· Revised Termination Rights. We have the right to terminate each management agreement: (i) at any time on 60 days’ written notice for convenience, (ii) immediately upon written notice for cause, as defined therein, (iii) on 60 days’ written notice given within 60 days after the end of an applicable calendar year for a performance reason, as defined therein, and (iv) by written notice during the 12 months following a change of control of RMR LLC, as defined therein. RMR LLC has the right to terminate the management agreements for good reason, as defined therein.

· Revised Termination Fee. If we terminate one or both of our management agreements for convenience, or if RMR LLC terminates one or both of our management agreements for good reason, as defined therein, we

F-25

have agreed to pay RMR LLC a termination fee in an amount equal to the sum of the present values of the monthly future fees, as defined therein, for the terminated management agreement(s) for the remaining term prior to the termination, which depending on the time of termination would be between 19 and 20 years. If we terminate one or both of our management agreements for a performance reason, as defined therein, we have agreed to pay RMR LLC the termination fee calculated as described above, but assuming a remaining term prior to the termination of 10 years. We are not required to pay any termination fee if we terminate our management agreements for cause, as defined therein or as a result of a change of control of RMR LLC, as defined therein.

Our Board of Trustees has given our Compensation Committee, which is comprised exclusively of our Independent Trustees, authority to act on our behalf with respect to our management agreements with RMR LLC. Our Governance Guidelines and the charter of our Compensation Committee together require the committee to annually review the terms of these agreements, evaluate RMR LLC's performance under the agreements and determine whether to terminate the management agreements.

The 2013 and 2014 amendments to the business and property management agreements described above were negotiated, reviewed, approved and adopted by our Compensation Committee and the 2015 amendments to the business and property management agreements described above were negotiated and reviewed by the Joint Special Committee, and were approved and adopted by our Compensation Committee.

RMR LLC Management Fees and Reimbursements. Pursuant to our business management agreement with RMR LLC, we recognized business management fees of $34,949,  $30,794 and $27,013 for 2015, 2014 and 2013, respectively. The business management fees we recognized for 2015, 2014 and 2013 are included in general and administrative expenses in our consolidated financial statements. The business management fee recognized for 2015 reflects a reduction of $1,743 for the amortization of the liability we recorded in connection with the Up-C Transaction, as further described above under “—Accounting for Investment in RMR Inc.” In accordance with the terms of our business management agreement, we issued, in aggregate, 68,983 of our common shares to RMR LLC as payment for a portion of the base business management fee we recognized for the period from January 1, 2015 to June 5, 2015, and 123,462 of our common shares to RMR LLC as payment for a portion of the base business management fee we recognized for 2014. In March 2013, we issued 21,968 of our common shares to RMR LLC for the incentive fees for 2012, respectively, pursuant to our business management agreement. No incentive fee was payable to RMR LLC under our business management agreement for 2015, 2014 or 2013.

Our property management agreement with RMR LLC provides for management fees for our MOB properties equal to 3.0% of gross collected rents and construction supervision fees equal to 5.0% of construction costs. The aggregate property management and construction supervision fees we recognized were $10,342,  $8,259 and $6,568 for 2015, 2014 and 2013, respectively. These amounts are included in property operating expenses or have been capitalized, as appropriate, in our consolidated financial statements.

We are generally responsible for all of our operating expenses, including certain expenses incurred by RMR LLC on our behalf. Our property level operating costs are generally incorporated into rents charged to our tenants, including certain payroll and related costs incurred by RMR LLC. The total of these property management related reimbursements paid to RMR LLC for the years ended December 31, 2015, 2014 and 2013 were $7,021,  $5,289 and $4,705, respectively, and these amounts are included in property operating expenses in our consolidated financial statements for these periods. We are generally not responsible for payment of RMR LLC's employment, office or administration expenses incurred to provide management services to us, except for the employment and related expenses of RMR LLC employees assigned to work exclusively or partly at our owned properties, our share of the wages, benefits and other related costs of centralized accounting personnel and our share of the staff employed by RMR LLC who perform our internal audit function.

We have historically awarded share grants to certain RMR LLC employees under our equity compensation plan. During the years ended December 31, 2015, 2014 and 2013, we made annual share grants to RMR LLC employees of 84,000,  81,700 and 82,600 of our common shares, respectively. Those grants had aggregate values of $1,321,  $1,750 and $1,888, respectively, based upon the closing price of our common shares on the NYSE on the dates of grant. One fifth of those restricted shares vested on the grant dates and one fifth vests on each of the next four anniversaries of the grant dates. These share grants to RMR LLC employees are in addition to the fees we paid to RMR LLC. In September 2015, we

F-26

purchased 13,113 of our common shares, at the closing price for our common shares on the NYSE on the date of purchase, from certain of our officers and other employees of RMR LLC in satisfaction of tax withholding and payment obligations in connection with the vesting of awards of restricted common shares. In addition, under our business management agreement we reimburse RMR LLC for our allocable costs for internal audit services, which amounts are subject to approval by our Compensation Committee. Our Audit Committee appoints our Director of Internal Audit. The aggregate amounts accrued for share grants to RMR LLC employees and internal audit costs for the years ended December 31, 2015, 2014 and 2013 were $1,340,  $1,835 and $1,877, respectively, and these amounts are included in our general and administrative expenses for these periods.

On occasion, we have entered into arrangements with former employees of RMR LLC in connection with the termination of their employment with RMR LLC, providing for the acceleration of vesting of restricted shares previously granted to them under our equity compensation plan. Additionally, each of our executive officers during 2015 received grants of restricted shares of other companies to which RMR LLC provides management services, including Five Star, in their capacities as officers of RMR LLC.

Pursuant to our business management agreement, RMR LLC may from time to time negotiate on our behalf with certain third party vendors and suppliers for the procurement of goods and services to us. As part of this arrangement, we may enter agreements with RMR LLC and other companies to which RMR LLC provides management services for the purpose of obtaining more favorable terms from such vendors and suppliers.

Leases with RMR LLC. We lease office space to RMR LLC in certain of our properties for RMR LLC’s property management offices. Pursuant to our lease agreements with RMR LLC, we recognized rental income from RMR LLC for leased office space of approximately $204,  $0 and $0 for the years ended December 31, 2015, 2014 and 2013; respectively. Our office space leases with RMR LLC are terminable by RMR LLC if our management agreements with RMR LLC are terminated. We may enter additional leases with RMR LLC for RMR LLC’s regional offices in the future.

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 $532,000, including a purchase price adjustment of $7,677, excluding working capital, and including the assumption of approximately $29,995 of mortgage debts. These 23 MOBs contain approximately 2,170,000 leasable square feet and are located in 12 states. In April 2015, SIR paid to us $1,316 to settle certain working capital activity for the 23 MOBs as of the acquisition date.

One of our Managing Trustees, Mr. Barry Portnoy, is a managing trustee of SIR and of GOV, which is SIR's largest shareholder. Our other Managing Trustee, Mr. Adam Portnoy, is the son of Mr. Barry Portnoy and a managing trustee of both SIR and GOV. Two of our Independent Trustees also serve as independent trustees of GOV and one of our Independent Trustees also serves as an independent trustee of SIR. Concurrently with SIR’s entering the merger agreement for the acquisition of CCIT, GOV, RMR LLC and Messrs. Barry Portnoy and Adam Portnoy entered into voting agreements with CCIT and VEREIT, Inc. (f/k/a American Realty Capital Properties, Inc.), a Maryland corporation and parent of the manager of CCIT, or VEREIT, pursuant to which they agreed, upon and subject to the terms and conditions of such agreements, to vote all common shares of SIR beneficially owned by them in favor of the issuance of additional common shares of SIR to CCIT stockholders pursuant to the Merger Agreement. These voting agreements also contain standstill provisions pursuant to which VEREIT has agreed, among other things, not to make unsolicited proposals to acquire us, SIR or GOV for a period of 36 months from August 30, 2014.

AIC. We, ABP Trust, Five Star, and four other companies to which RMR LLC provides management services currently own AIC, an Indiana insurance company, and are parties to an amended and restated shareholders agreement regarding AIC. On May 9, 2014, as a result of a change in control of EQC,  as defined in the amended and restated shareholders agreement, we and the other AIC shareholders purchased pro rata the AIC shares EQC owned in accordance with the terms of that agreement. Pursuant to that purchase, we purchased 2,857 AIC shares from EQC for $825. Following these purchases, we and the other remaining six shareholders each own approximately 14.3% of AIC. As of December 31, 2015, we have invested $6,034 in AIC since its formation in 2008.

All of our Trustees and all of the trustees and directors of the other AIC shareholders currently serve on the board of directors of AIC. RMR LLC provides management and administrative services to AIC pursuant to a management and

F-27

administrative services agreement with AIC. Pursuant to this agreement, AIC pays RMR LLC a service fee equal to 3.0% of the total annual earned premiums payable under then active policies issued or underwritten by AIC or by a vendor or an agent of AIC on its behalf or in furtherance of AIC’s business. The shareholders agreement among us, the other shareholders of AIC and AIC includes arbitration provisions for the resolution of disputes.

We and the other shareholders of AIC have historically participated in a combined property insurance program arranged by AIC providing $500,000 of coverage and with respect to which AIC is a reinsurer of certain coverage amounts. In June 2015, we and the other shareholders of AIC renewed our participation in this program. In connection with that renewal, we purchased a three year combined property insurance policy providing $500,000 of coverage annually with the premiums to be paid annually, a one year standalone policy providing $1,000,000 of coverage for one very large property we own and a one year combined policy providing certain other coverage. Our annual premiums for this property insurance were $2,785, $3,118 and $4,748 in 2015, 2014 and 2013, respectively. Although we own less than 20% of AIC, we use the equity method to account for this investment because we believe that we have significant influence over AIC as all of our Trustees are also directors of AIC. Our investment in AIC had a carrying value of $6,827, $6,827 and $5,913 as of December 31, 2015, 2014 and 2013, respectively, which amounts are included in other assets on our consolidated balance sheets. We recognized income of $20, $87 and $334 related to our investment in AIC for 2015, 2014 and 2013, respectively.

We periodically consider the possibilities for expanding our insurance relationships with AIC to include other types of insurance and may in the future participate in additional insurance offerings AIC may provide or arrange. We may invest additional amounts in AIC in the future if the expansion of this insurance business requires additional capital, but we are not obligated to do so.

Directors’ and Officers’ Liability Insurance. We, RMR Inc., Five Star, and certain companies to which RMR LLC provides management services participate in a combined directors' and officers' liability insurance policy. This combined policy currently provides for $10,000 of combined primary coverage and expires in September 2017. In August 2015, we also obtained separate non-combined directors’ and officers’ liability insurance policies providing $20,000 of aggregate excess coverage plus $5,000 of excess non-indemnifiable coverage, which policies expire in September 2016. We paid aggregate premiums of $472,  $736 and $343 in 2015, 2014 and 2013, respectively, for these policies. The premiums for the combined policies were allocated among the insured companies after consultation with the insurance broker and approval by each company’s board and independent trustees or directors as applicable.

Note 6. Indebtedness

Our principal debt obligations at December 31, 2015 were: (1) outstanding borrowings under our $1,000,000 unsecured revolving credit facility; (2) five public issuances of senior unsecured notes, including: (a) $400,000 principal amount at an annual interest rate of 3.25% due 2019, (b) $200,000 principal amount at an annual interest rate of 6.75% due 2020, (c) $300,000 principal amount at an annual interest rate of 6.75% due 2021, (d) $250,000 principal amount at an annual interest rate of 4.75% due 2024 and (e) $350,000 principal amount at an annual interest rate of 5.625% due 2042; (3) our $350,000 principal amount term loan due 2020; (4) our $200,000 principal amount term loan due 2022; and (5) $667,535 aggregate principal amount of mortgages secured by 56 of our properties (57 buildings) with maturity dates between 2016 and 2043.  The 56 mortgaged properties (57 buildings) had a carrying value (before accumulated depreciation) of $1,083,616 at December 31, 2015.  We also had two properties subject to capital leases with lease obligations totaling $12,156 at December 31, 2015; these two properties had a carrying value before depreciation of $35,901 at December 31, 2015. The capital leases expire in 2026.

Our revolving credit facility agreement includes an accordion feature under which maximum borrowings under the facility may be increased to up to $1,500,000 in certain circumstances. In September 2015, we partially exercised this accordion feature and increased the maximum borrowings available under the facility to $1,000,000 from the previous amount of $750,000. All other material terms of our revolving credit facility agreement remained unchanged.  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.  Our revolving credit facility agreement provides that we can borrow, repay and re-borrow funds available under our revolving credit facility until maturity, and no principal repayment is due until maturity.  Our revolving credit facility requires annual interest to be paid at LIBOR plus a premium, which was 130 basis points as of

F-28

December 31, 2015, 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 December 31, 2015, the annual interest rate payable on borrowings under our revolving credit facility was 1.7%, and the weighted average annual interest rates for borrowings under our revolving credit facility was 1.5%, 1.4% and 1.6% for the three years ended December 31, 2015, 2014 and 2013, respectively. As of December 31, 2015, we had $775,000 outstanding and $225,000 available for borrowing, and as of February 22, 2016, we had $593,000 outstanding and $407,000 available for borrowing under our revolving credit facility. We incurred interest expense and other associated costs related to our revolving credit facility of $9,252, $3,094 and $3,781 for the years ended December 31, 2015, 2014 and 2013, respectively.

In September 2015, we entered into a term loan agreement with a syndicate of lenders, pursuant to which we obtained a $200,000 unsecured term loan. This term loan matures in September 2022, and is prepayable without penalty beginning September 29, 2017. In addition, this term loan includes an accordion feature under which maximum borrowings may be increased to up to $400,000 in certain circumstances. This term loan requires annual interest to be paid at LIBOR plus a premium of 180 basis points that is subject to adjustment based upon changes to our credit ratings. We used the net proceeds from this term loan to repay amounts outstanding under our revolving credit facility. As of December 31, 2015, the annual interest rate payable for amounts outstanding under this term loan was 2.2%. The weighted average annual interest rate for amounts outstanding under our term loan was 2.0% for the period from September 28, 2015 (the day we entered into this term loan agreement) to December 31, 2015. We incurred interest expense and other associated costs related to this term loan of $1,061 for the period from September 28, 2015 (the day we entered into this term loan agreement) to December 31, 2015.

In addition to our $200,000 term loan, we also have a $350,000 unsecured term loan, which we borrowed in 2014. This term loan matures in January 2020, and is prepayable without penalty at any time.  This term loan includes an accordion feature under which maximum borrowings may be increased to up to $700,000 in certain circumstances. This term loan requires annual interest to be paid at LIBOR plus a premium of 140 basis points that is subject to adjustment based upon changes to our credit ratings. As of December 31, 2015, the annual interest rate payable on amounts outstanding under this term loan was 1.6%.  The weighted average annual interest rate for amounts outstanding under this term loan was 1.6% for the year ended December 31, 2015 and 1.6% for the period from May 30, 2014 (the day we entered into this term loan agreement) to December 31, 2014. We incurred interest expense and other associated costs related to this term loan of $5,686 for the year ended December 31, 2015 and $3,263 for the period from May 30, 2014 (the day we entered into this term loan agreement) to December 31, 2015.

In February 2016, we sold $250,000 of 6.25% senior unsecured notes due 2046, raising net proceeds of approximately $242,125 after underwriting discounts and before expenses. We have also granted the underwriters an option to purchase up to an additional $37,500 in aggregate principal amount of the notes.  We used the net proceeds of this offering to repay amounts outstanding under our revolving credit facility and for general business purposes.

Our revolving credit facility and term loan agreements and our senior unsecured notes indentures and their supplements provide for acceleration of payment of all amounts due thereunder upon the occurrence and continuation of certain events of default, such as, in the case of our revolving credit facility and term loan agreements, a change of control of us, which includes RMR LLC ceasing to act as our business manager and property manager.Our revolving credit facility and term loan agreements and our senior unsecured notes indentures and their supplements also contain a number of covenants, including covenants that restrict our ability to incur debts, and generally require us to maintain certain financial ratios, and our revolving credit facility and term loan agreements restrict our ability to make distributions under certain circumstances. We believe we were in compliance with the terms and conditions of the respective covenants under our senior unsecured notes indentures and their supplements and our revolving credit facility and term loan agreements at December 31, 2015.

In December 2014, we entered an agreement to acquire the 38 senior living communities discussed in Note 3 above. Simultaneous with entering this agreement, we obtained 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 early extinguishment of debt in the first quarter of 2015 in connection with that termination. As discussed in Note 3 above, we acquired these senior living communities in May and September 2015 and financed the acquisition using cash on hand, borrowings under our

F-29

revolving credit facility and the assumption of approximately $151,477 of mortgage debts with a weighted average annual interest rate of 4.57%. These mortgages have maturity dates from October 2018 through July 2019. We determined the fair value of the assumed mortgage debts using a market approach based upon Level 3 inputs (significant other unobservable inputs) in the fair value hierarchy provided by the Fair Value Topic of the Codification.

In connection with two of the 23 MOBs we acquired in January 2015, as further discussed in Note 3 above, we assumed $29,955 of mortgage debts which we recorded at their aggregate fair value of $31,029.  These two assumed mortgage debts have a contractual weighted average annual interest rate of 4.73% and mature in July 2016 and October 2022.  We determined the fair value of the assumed mortgages using a market approach based upon Level 3 inputs (significant other unobservable inputs) in the fair value hierarchy provided by the Fair Value Topic of the Codification.

In November 2015, we prepaid all $250,000 of our 4.30% senior unsecured notes due January 2016. As a result, we recognized a loss on early extinguishment of debt of $175 for the year ended December 31, 2015.

In February 2015, we repaid at maturity a mortgage that encumbered one of our properties that had a principal balance of $29,227 and an annual interest rate of 6.02%. In April 2015, we prepaid a mortgage that encumbered one of our properties that had a principal balance of $6,274 and an annual interest rate of 5.81%. In May 2015, we prepaid four mortgages encumbering four properties with an aggregate principal balance of $15,077 and a weighted average annual interest rate of 5.70%. In June 2015, we repaid at maturity a mortgage encumbering one property with a principal balance of $4,867 and an annual interest rate of 5.65%. Also in June 2015, we prepaid a mortgage encumbering one property with a principal balance of $4,351 and an annual interest rate of 5.81%. In October 2015, we prepaid two mortgages encumbering one property with a principal balance of $52,000 and a weighted average annual interest rate of 5.64%. As a result, we recognized losses on early extinguishment of debt of $290 for the year ended December 31, 2015.

In January 2016, we prepaid a mortgage that encumbered one of our properties that had a principal balance of $6,115 and an annual interest rate of 5.97%.

In June 2014, we repaid at maturity mortgages that encumbered two of our properties that had an aggregate principal balance of $35,807 and a weighted average annual interest rate of 5.8%. In October 2014, we prepaid at par our $14,700 loan incurred in connection with certain revenue bonds scheduled to mature in December 2027. That loan had an annual interest rate of 5.875%.  Also in October 2014, we prepaid a mortgage note scheduled to mature in May 2015 that encumbered one of our properties that had a principal balance of $11,900 and an annual interest rate of 6.25%. In December 2014, we prepaid a mortgage note scheduled to mature in July 2015 that encumbered one of our properties that had a principal balance of $11,308 and an annual interest rate of 6.37%.  As a result, we recognized losses on early extinguishment of debt of $12 for the year ended December 31, 2014.

At December 31, 2015 and 2014, our outstanding senior unsecured notes and secured debt consisted of the following:

(1) The principal balances are the amounts stated in the contracts. In accordance with U.S. generally accepted accounting principles, our carrying values and recorded interest expense may be different because of market conditions at the time we assumed certain of these debts. As of December 31, 2015 and 2014, the unamortized net premiums on certain of these mortgages were $3,267 and $2,937, respectively.

(2) In 2015, we repaid this debt.

(3) In 2016, we repaid this debt.

(4) These two mortgages are collateralized by one MOB property acquired in July 2008.

Interest on our senior unsecured notes are payable either semi‑annually or quarterly in arrears; however, no principal repayments are due until maturity. Required monthly payments on our mortgages include principal and interest. Payments under our capital leases are due monthly. We include amortization of capital lease assets in depreciation expense.

Required principal payments on our outstanding debt as of December 31, 2015, are as follows:

F-31

2016	$	130,380
2017	$	69,838
2018	$	884,768
2019	$	720,919

Note 7. Fair Value of Assets and Liabilities

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

							Significant
			Quoted Prices in Active		Significant Other		Unobservable
			Markets for Identical		Observable Inputs		Inputs
Description	Total		Assets (Level 1)		(Level 2)		(Level 3)
Recurring Fair Value Measurements
Assets:
Investments in available for sale securities(1)	$	51,472	$	51,472	$	—	$	—
Non-Recurring Fair Value Measurements
Assets:
Assets held for sale(2)	$	653	$	—	$	—	$	653
Liabilities:
Additional purchase consideration(3)	$	1,000	$	—	$	—	$	1,000

(1) Our investments in available for sale securities include our 4,235,000 common shares of Five Star and our 2,637,408 shares of RMR Inc. class A common stock. The fair values of these shares are based upon quoted prices at December 31, 2015 in active markets (Level 1 inputs). Our historical cost basis for our Five Star and RMR Inc. shares is $14,230 and $69,826, respectively, as of December 31, 2015. The unrealized loss of $747 for our Five Star shares and $31,821 for our RMR Inc. shares as of December 31, 2015 is included in cumulative other comprehensive income (loss) in our consolidated balance sheets. We evaluated the decline in the fair value of the Five Star and RMR Inc. shares and determined that based on the severity and duration of the decline, and our ability and intent to hold the investment for a reasonable period of time sufficient for a forecasted recovery of fair value, we do not consider these investments to be other-than-temporarily impaired at December 31, 2015.

(2) Assets held for sale consist of one vacant land parcel held for sale as of December 31, 2015. The land parcel is recorded at its estimated fair value less costs to sell. We used an accepted offer from a third party to purchase this parcel to determine its fair value. We also have one senior living community (one building) classified as held for sale as of December 31, 2015. The senior living community assets are recorded at their carrying value, which is lower than what we believe its fair value less estimated costs to sell to be at December 31, 2015.  The carrying value of this senior living community is not included in the above table.

(3) In May 2015, we acquired one senior living community located in Georgia for approximately $9,750, excluding closing costs. Pursuant to the purchase agreement, $1,000 of the purchase price has been withheld until the seller satisfies certain conditions. We anticipate these conditions will be satisfied and therefore have recorded the withheld $1,000 as a liability as of December 31, 2015. We estimate the fair value of this liability at December 31, 2015 to be $1,000, which is the amount we have agreed to pay in cash when the applicable conditions are satisfied (Level 3 inputs). This liability is included in other liabilities in our consolidated balance sheets as described in Note 3.

We estimate the fair values of our senior unsecured notes using an average of the bid and ask price of our outstanding five issuances of senior notes (Level 2 inputs) on or about December 31, 2015.  The fair values of these

F-32

senior note obligations exceed their aggregate book values of $1,495,066 by $70,077 because these notes were trading at premiums to their face amounts.

We estimate the fair values of our secured debts 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 debts exceeds their book value of $667,535 by $45,321 because current market interest rates are lower than the market interest rates at the time we assumed these secured debts. 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 debts, our additional financial instruments include rents receivable, cash and cash equivalents, restricted cash and other unsecured obligations. The fair values of these additional financial instruments approximate their carrying values at December 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. Concentration of Credit Risk

The assets included in these financial statements are primarily income producing senior housing and healthcare related real estate located throughout the United States. The following is a summary of the assets leased and rents earned from our significant lessee as of and for the years ended December 31, 2015 and 2014:

(1) Represents real and personal property leased to our tenants at historical cost after impairment losses and before depreciation. Excludes properties classified as held for sale.

As discussed above, Five Star is our former subsidiary. As of December 31, 2015, Five Star also managed a portfolio of 60 senior living communities for our account.

See Note 5 for further information relating to our leases and management arrangements with Five Star.

Note 9. Segment Reporting

As of December 31, 2015, we have four operating segments, of which three are separate reporting segments. The first reporting segment includes triple net senior living communities that provide short term and long term residential care and other services for residents. The second reporting segment includes managed senior living communities that provide short term and long term residential care and other services for residents. The third reporting segment includes MOBs. Our fourth segment includes the remainder of our operations, including certain properties that offer fitness, wellness and spa services to members, which we do not consider to be sufficiently material as to constitute a separate reporting segment, and all of our other operations.

A reconciliation of our effective tax rate and the U.S. federal statutory income tax rate is as follows:

F-36

	For the year ended December 31,
	2015		2014		2013
Taxes at statutory U.S. federal income tax rate	35.0	%	35.0	%	35.0	%

Deferred income tax balances reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities on our consolidated balance sheets and the amounts used for income tax purposes and are stated at enacted tax rates expected to be in effect when taxes are actually paid or recovered. Significant components of our deferred tax assets and liabilities are as follows:

Deferred tax liabilities are included in other liabilities in the accompanying consolidated balance sheets.

Because of our TRSs’ short operating history and history of losses, we are not able to conclude that it is more likely than not we will realize the future benefit of our deferred tax assets; thus we have provided a 100% valuation allowance as of December 31, 2015 and 2014. If and when we believe it is more likely than not that we will recover our deferred tax assets, we will reverse the valuation allowance as an income tax benefit in our consolidated statement of comprehensive income. As of December 31, 2015, our consolidated TRSs had net operating loss carry forwards for federal income tax purposes of approximately $71,283, which, if unused, begin to expire in 2031. In the normal course of business, income tax authorities in various income tax jurisdictions conduct routine audits of our income tax returns filed in prior years. Income tax years subsequent to 2010 may be open to examination in some of the income tax jurisdictions in which we operate.

Note 11. Weighted Average Common Shares

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):

	Year Ended December 31,

Note 13. Pro Forma Information (unaudited)

In January 2015, we acquired 23 properties aggregate purchase price of $539,000, excluding net credits received of $7,377 related to debt assumption costs and outstanding tenant improvement allowances and excluding closing costs, and including the assumption of approximately $29,995 of mortgage debts with a weighted average annual interest rate of 4.73%. We recognized rental income, property operating expenses and interest expense from this acquisition of $38,593,  $6,833 and $1,000, respectively, for the year ended December 31, 2015. In February 2015, we sold 31,050,000 of our common shares in a public offering raising net proceeds of approximately $659,496 after underwriting discounts and expenses.

In May and September 2015, we acquired 39 senior living communities for an aggregate purchase price of $808,250, excluding closing costs, and including the assumption of $151,477 of mortgage debts with a weighted average annual interest rate of 4.57%. Twenty of the 39 communities are triple net leased, and we recognized rental income from these 20 communities of $23,756 and interest expense of $1,427 for the year ended December 31, 2015. We recognized residents fees and services, property operating expenses and interest expense for the remaining 19 managed senior living communities of $35,814,  $25,514 and $2,774, respectively, for the year ended December 31, 2015. Also in May 2015, we acquired one managed senior living community for approximately $9,750, excluding closing costs. This is a newly constructed community and is located adjacent to another community that we own. The operations of this community and the community we previously owned are now conducted as a single integrated community under one management agreement. In September 2015, we entered into a $200,000 term loan agreement, which requires interest at a rate of LIBOR plus a premium of 180 basis points.

F-38

During 2014, we purchased two senior living communities and two MOBs (three buildings) for $1,210,014. We also assumed $15,630 of mortgage debt with an annual interest rate of 6.28% related to one of our 2014 acquisitions. We recognized residents fees and services and property operating expenses of $887 and $647, respectively, for the year ended December 31, 2014 for the two senior living community acquisitions we acquired in 2014. We recognized rental income, property operating expenses and interest expense of $67,294,  $14,179 and $631, respectively, for the year ended December 31, 2014 for the two MOBs (three buildings) we acquired in 2014. In April 2014, we issued 15,525,000 common shares in a public offering, raising net proceeds of approximately $322,807.  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. 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 years ended December 31, 2015 and 2014 as if the 2015 and 2014 acquisition (excluding the newly constructed managed senior living community) and financing activities described in the preceding paragraphs had occurred on January 1, 2014, and January 1, 2013, respectively.  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 from our existing leases or leases we may enter into during and after 2015, and for other reasons.
