We are a REIT with a geographically diverse portfolio of seniors housing and healthcare properties throughout the United States and Canada. As of December 31, 2011, we owned 1,378 properties located in 46 states, the District of Columbia and two Canadian provinces, consisting of: 678 seniors housing communities; 396 skilled nursing facilities; 47 hospitals; 249 MOBs; and eight personal care facilities. We also were in the process of developing three properties as of December 31, 2011. We are headquartered in Chicago, Illinois and have been a constituent member of the S&P 500® Index, a leading indicator of the large cap U.S. equities market, since March 2009.

Our primary business focuses on acquiring and owning seniors housing and healthcare properties and leasing those properties to unaffiliated tenants or operating those properties through independent third-party managers. Through our Lillibridge Healthcare Services, Inc. ("Lillibridge") subsidiary and our ownership interest in PMB Real Estate Services LLC ("PMBRES"), which we acquired in July 2011 in connection with our acquisition of NHP, we also provide MOB management, leasing, marketing, facility development and advisory services to highly rated hospitals and health systems throughout the United States. In addition, from time to time, we make mortgage loan and other investments relating to seniors housing and healthcare operators or properties.

Ventas was incorporated in Kentucky in 1983, commenced operations in 1985 and reorganized as a Delaware corporation in 1987. We currently operate through three reportable business segments: triple-net leased properties, senior living operations and MOB operations. See our Consolidated Financial Statements and the related notes, including "Note 2—Accounting Policies," included in Part II, Item 8 of this Annual Report on Form 10-K.

Our business strategy focuses on three principal objectives: (1) generating consistent, reliable and growing cash flows; (2) maintaining a well-diversified portfolio; and (3) preserving our financial strength, flexibility and liquidity.

We strive to enhance shareholder value by generating consistent, reliable and growing cash flows from our seniors housing and healthcare assets. To achieve this objective, we endeavor to balance our portfolio through a combination of long-term triple-net leases that provide steady contractual growth, seniors housing operating assets that allow for greater growth potential than our fixed rent escalators, and MOBs that provide stable cash flows.

We believe that maintaining a portfolio of properties and mortgage loan and other investments diversified by asset class, tenant/operator/manager, geographic location, revenue source and business model makes us less susceptible to regional economic downturns and adverse changes in regulation or

reimbursement rates or methodologies in any single state or with respect to any particular asset type. Portfolio diversification also reduces our exposure to any individual tenant/operator/manager and diminishes the risk that a single event could materially harm our business.

A strong, flexible balance sheet and excellent liquidity position us favorably to create and exploit growth opportunities through acquisitions, investments and development projects. We intend to maintain our financial strength and invest profitably by actively managing our leverage, lowering our cost of capital and preserving our access to multiple sources of liquidity, such as unsecured bank debt, mortgage financings and the public debt and equity markets.

Over the last twelve months, we have completed several significant transactions and financing activities, including without limitation the following:

As of December 31, 2011, we had ownership interests in 1,378 seniors housing and healthcare properties as follow:

Through Lillibridge and PMBRES, we also provided management and leasing services to third parties with respect to 44 MOBs as of December 31, 2011.

The following table provides an overview of our consolidated portfolio of properties and other investments, excluding development projects, as of and for the year ended December 31, 2011:

Seniors Housing Communities. Our seniors housing communities include independent and assisted living communities, continuing care retirement communities and communities providing care for individuals with Alzheimer's disease and other forms of dementia or memory loss. These communities offer studio, one bedroom and two bedroom residential units on a month-to-month basis primarily to elderly individuals requiring various levels of assistance. Basic services for residents of these communities include housekeeping, meals in a central dining area and group activities organized by the staff with input from the residents. More extensive care and personal supervision, at additional fees, are also available for such needs as eating, bathing, grooming, transportation, limited therapeutic programs and medication administration, which allow residents certain conveniences and enable them to live as independently as possible according to their abilities. These services are often met by home health providers, close coordination with the resident's physician and skilled nursing facilities. Charges for room, board and services are generally paid from private sources.

Skilled Nursing Facilities. Our skilled nursing facilities provide rehabilitative, restorative, skilled nursing and medical treatment for patients and residents who do not require the high technology, care-intensive, high cost setting of an acute care or rehabilitation hospital. Treatment programs include physical, occupational, speech, respiratory and other therapies, including sub-acute clinical protocols such as wound care and intravenous drug treatment. Charges for these services are generally paid from a combination of government reimbursement and private sources.

Hospitals. Substantially all of our hospitals are operated as long-term acute care hospitals, which have a Medicare average length of stay greater than 25 days and serve medically complex, chronically ill patients who require a high level of monitoring and specialized care, but whose conditions do not necessitate the continued services of an intensive care unit. The operators of these hospitals have the capability to treat patients who suffer from multiple systemic failures or conditions such as neurological disorders, head injuries, brain stem and spinal cord trauma, cerebral vascular accidents, chemical brain injuries, central nervous system disorders, developmental anomalies and cardiopulmonary disorders. Chronic patients often depend on technology for continued life support, such as mechanical ventilators, total parenteral nutrition, respiration or cardiac monitors and dialysis machines, and, due to their severe medical conditions, generally are not clinically appropriate for admission to a nursing facility or rehabilitation hospital. All of our long-term acute care hospitals are freestanding facilities, and we do not own any "hospitals within hospitals." We also own two hospitals focused on providing children's care and five rehabilitation hospitals devoted to the rehabilitation of patients with various neurological, musculoskeletal, orthopedic and other medical conditions following stabilization of their acute medical issues.

Medical Office Buildings. Our MOBs are typically multi-tenant properties leased to several different unrelated medical practices, although they can be associated with a large single specialty or multi-specialty group. Tenants include physicians, dentists, psychologists, therapists and other healthcare providers, with space devoted to patient examination and treatment, diagnostic imaging, outpatient surgery and other outpatient services. While MOBs are similar to commercial office buildings, they require more plumbing, electrical and mechanical systems to accommodate physicians' requirements such as sinks in every room, brighter lights and specialized medical equipment. As of December 31, 2011, we owned or managed more than 14 million square feet of MOBs, a significant majority of which are "on campus," meaning on or near an acute care hospital campus.

Personal Care Facilities. Our personal care facilities provide specialized care, including supported living services, neurorehabilitation, neurobehavioral management and vocational programs, for persons with acquired or traumatic brain injury.

As of December 31, 2011, we had $276.2 million of net loans receivable relating to seniors housing and healthcare operators or properties. See "Note 6—Loans Receivable" of the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K. In addition, we had marketable debt securities classified as available-for-sale and having an aggregate amortized cost basis of $41.2 million and a fair value of $43.3 million as of December 31, 2011.

Our portfolio of seniors housing and healthcare properties is broadly diversified by geography throughout the United States and Canada, with properties in only one state (California) accounting for more than 10% of our total revenues for the year ended December 31, 2011.

The following table shows our rental income and resident fees and services derived by geographic location for the year ended December 31, 2011:

As of December 31, 2011, we operated through three reportable business segments: triple-net leased properties, senior living operations and MOB operations. See "Note 20—Segment Information" of the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K for more information about our business segments and the geographic diversification of our portfolio of properties.

Our skilled nursing facilities and hospitals are generally subject to federal, state and local licensure statutes and statutes that may require regulatory approval, in the form of a certificate of need ("CON") issued by a governmental agency with jurisdiction over healthcare facilities, prior to the expansion of existing facilities, construction of new facilities, addition of beds, acquisition of major equipment or introduction of new services. CON requirements, which are not uniform throughout the United States, may restrict our or our operators' ability to expand our properties in certain circumstances.

The following table shows our rental income for the year ended December 31, 2011 derived by skilled nursing facilities and hospitals in states with and without CON requirements:

As of December 31, 2011, Atria, Sunrise, Brookdale Senior Living and Kindred operated or managed, as applicable, approximately 19.0%, 14.4%, 13.0% and 5.0%, respectively, of our real estate investments based on their gross book value (including amounts held for sale as of December 31, 2011).

The following table shows the percentage of our revenues and net operating income ("NOI"—defined as total revenues, less interest and other income, property-level operating expenses and medical office building services costs) for the year ended December 31, 2011 (including amounts in discontinued operations) received by or attributed to our top triple-net lease tenants and our senior living operations managed by independent third parties:

Each of our master lease agreements with Kindred (the "Kindred Master Leases") and our leases with Brookdale Senior Living is a triple-net lease that obligates the tenant to pay all property-related expenses, including maintenance, utilities, repairs, taxes, insurance and capital expenditures, and to comply with the terms of the mortgage financing documents, if any, affecting the properties. In addition, each of these leases have guaranty and cross-default provisions tied to other leases with the same tenant, as well as bundled lease renewals (as described in more detail below).

Because the properties we lease to Kindred and Brookdale Senior Living account for a significant portion of our revenues and NOI, our financial condition and results of operations could be weakened and our ability to service our indebtedness and to make distributions to our stockholders could be limited if either Kindred or Brookdale Senior Living were unable or unwilling to satisfy its obligations to us or to renew its leases with us upon expiration of the terms thereof. We cannot provide any assurance that Kindred and Brookdale Senior Living will have sufficient assets, income and access to financing to enable them to satisfy their respective obligations to us, and any inability or unwillingness by Kindred or Brookdale Senior Living to do so could have a material adverse effect on our business, financial condition, results of operations and liquidity, on our ability to service our indebtedness and other obligations and on our ability to make distributions to our stockholders, as required for us to continue to qualify as a REIT (a "Material Adverse Effect"). We also cannot provide any assurance that Kindred and Brookdale Senior Living will elect to renew their respective leases with us upon expiration of their terms or that we will be able to reposition any properties that are not renewed on a timely basis or on the same or better economic terms, if at all. See "Risks Factors—Risks Arising from Our Business—We depend on Kindred and Brookdale Senior Living for a significant portion of our revenues and operating income; Any inability or unwillingness by Kindred or Brookdale Senior Living to satisfy its obligations under its agreements with us could have a Material Adverse Effect on us" included in Item 1A of this Annual Report on Form 10-K.

Kindred Master Leases. The aggregate annual rent we receive under each Kindred Master Lease is referred to as "base rent." Base rent escalates on May 1 of each year at a specified rate over the prior period base rent, contingent upon the satisfaction of specified facility revenue parameters. The annual rent escalator under three of our four Kindred Master Leases is 2.7%, and the annual rent escalator under the fourth Kindred Master Lease is based on year-over-year changes in CPI, subject to a floor of 2.25% and a ceiling of 4%. Assuming the applicable facility revenue parameters are met, we currently expect that base rent due under the Kindred Master Leases for the period from May 1, 2012 through April 30, 2013 will be approximately $261.5 million. See "Note 3—Concentration of Credit Risk" of the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K.

The 197 properties we lease to Kindred pursuant to the Kindred Master Leases are grouped into bundles or renewal groups (each, a "renewal group") containing a varying number of properties. All properties within a single renewal group have the same primary lease term of ten to fifteen years (commencing May 1, 1998), and each renewal group is subject to three successive five-year renewal terms at the tenant's option, provided certain conditions are satisfied.

The current lease term for ten renewal groups covering a total of 89 properties leased to Kindred (the "Renewal Assets") will expire on April 30, 2013 unless Kindred provides us with renewal notices with respect to one or more of those bundles on or before April 30, 2012. In November 2011, we received renewal notices from Kindred with respect to two renewal groups covering a total of sixteen Renewal Assets (the "Early Renewal Assets") and collectively representing approximately $23 million of current annual base rent. In December 2011, we initiated a fair market rental reset process with respect to certain Early Renewal Assets. While we believe that aggregate annual base rent for those Early Renewal Assets is likely to increase as a result of the reset process, we cannot provide any assurance regarding the final determination of fair market rent, which is highly speculative and may be influenced by a variety of factors. In addition, in certain cases Kindred may have the right to revoke its renewal of those Early Renewal Assets for which we initiated the fair market rental reset process.

The remaining eight renewal groups covering a total of 73 Renewal Assets collectively represent approximately $99 million of current annual base rent, and each renewal group contains six or more properties, including at least one hospital. Kindred is required to continue to perform all of its obligations under the applicable Kindred Master Lease for the Renewal Assets within any renewal group that is not renewed until expiration of the term on April 30, 2013, including without limitation

payment of all rental amounts. Therefore, as to any renewal group for which we do not receive a renewal notice, we will have at least one year to arrange for the repositioning of the applicable Renewal Assets with new operators. Moreover, we own or have the rights to all licenses and CONs at the properties, and Kindred has extensive and detailed obligations to cooperate and ensure an orderly transition of the properties to another operator.

We cannot provide any assurance that Kindred will elect to renew any or all of the remaining eight renewal groups whose lease expires April 30, 2013, that Kindred will not revoke its renewal of the Early Renewal Assets for which we initiated the fair market rental reset process, or that we will be able to reposition any or all non-renewed assets on a timely basis or on the same or better economic terms, if at all. See "Risk Factors—Risks Arising from Our Business—If we must replace any of our tenants or operators, we might be unable to reposition the properties on as favorable terms, or at all, and we could be subject to delays, limitations and expenses, which could have a Material Adverse Effect on us" included in Item 1A of this Annual Report on Form 10-K.

The current lease term for 108 properties leased to Kindred pursuant to the Kindred Master Leases and not comprising the Renewal Assets will expire on April 30, 2015, subject to Kindred's two sequential five-year renewal options for those assets.

Brookdale Senior Living Leases. Our leases with Brookdale Senior Living have primary terms of fifteen years (commencing in 2004) and are subject to two successive renewal terms of either five or ten years each at the tenant's option, provided certain conditions are satisfied.

Under the terms of our leases with Brookdale Senior Living that we assumed in connection with our acquisition of Provident Senior Living Trust ("Provident") in 2005, Brookdale Senior Living is obligated to pay base rent, which escalates on January 1 or November 1 of each year by an amount equal to the lesser of (i) four times the percentage increase in CPI during the immediately preceding year or (ii) either 2.5% or 3%, depending on the lease. Under the terms of the lease with respect to our remaining "Grand Court" property (as described in more detail below), Brookdale Senior Living is obligated to pay base rent, which escalates on February 1 of each year by an amount equal to the greater of (i) 2% or (ii) 75% of the increase in CPI during the immediately preceding year. In February 2012, we sold nine of our original ten "Grand Court" properties to Brookdale Senior Living for aggregate consideration of $121.3 million, including a lease termination fee of $1.8 million. The current aggregate annual contractual cash base rent due to us from Brookdale Senior Living for 2012, excluding variable interest that Brookdale Senior Living is obligated to pay as additional rent based on certain floating rate mortgage debt assumed by us in the Provident acquisition, is approximately $158.1 million (excluding properties included in investments in unconsolidated entities and properties held for sale as of December 31, 2011). The current aggregate annual contractual base rent (computed in accordance with U.S. generally accepted accounting principles ("GAAP")) due to us from Brookdale Senior Living for 2012, excluding the variable interest, is approximately $161.2 million (excluding properties included in investments in unconsolidated entities and properties held for sale as of December 31, 2011). See "Note 3—Concentration of Credit Risk" and "Note 14—Commitments and Contingencies" of the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K.

As of December 31, 2011, Atria and Sunrise, collectively, provided comprehensive property management and accounting services with respect to 197 of our seniors housing communities for which we pay an annual management fee pursuant to long-term management agreements. Each management agreement with Atria has a term of ten years commencing in 2011, subject to successive automatic ten-year renewal periods, and each management agreement with Sunrise has a term of 30 years commencing as early as 2004. Under the Sunrise management agreements, our management fee was reduced to 3.75% of revenues generated by the applicable properties for 2011, but will revert to 6% of revenues generated by the applicable properties (with a range of 5% to 7%) for 2012 and thereafter. See "Note 3—Concentration of Credit Risk" of the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K.

Because Atria and Sunrise manage, but do not lease, our properties, we are not directly exposed to their credit risk in the same manner or to the same extent as our triple-net tenants. However, we rely on our managers' personnel, good faith, expertise, historical performance, technical resources and information systems, proprietary information and judgment to manage our seniors housing communities efficiently and effectively. We also rely on our managers to set resident fees and otherwise operate those properties in compliance with the terms of our management agreements. Although we have various rights as the property owner under our management agreements, Atria's or Sunrise's inability or unwillingness to satisfy its obligations under those agreements, to efficiently and effectively manage our properties or to provide timely and accurate accounting information with respect thereto could have a Material Adverse Effect on us. In addition, significant changes in Atria's or Sunrise's senior management or any adverse developments in their businesses and affairs or financial condition could have a Material Adverse Effect on us. See "Risk Factors—Risks Arising from Our Business—The properties managed by Atria and Sunrise account for a significant portion of our revenues and operating income; Although Atria and Sunrise are managers, not tenants, of our properties, adverse developments in their businesses and affairs or financial condition could have a Material Adverse Effect on us" included in Item 1A of this Annual Report on Form 10-K.

We generally compete in the acquisition, leasing and financing of seniors housing and healthcare properties with publicly traded, private and non-listed healthcare REITs, real estate partnerships, healthcare providers, healthcare lenders and other investors, including without limitation developers, banks, insurance companies, pension funds, government sponsored entities and private equity firms. Some of our competitors may have greater financial resources and lower costs of capital than we do. Increased competition makes it more challenging for us to identify and successfully capitalize on opportunities that meet our objectives, as our ability to compete in those areas is affected by, among other factors, the availability of suitable acquisition or investment targets, our ability to negotiate acceptable acquisition or investment terms and our access to and cost of capital. See "Risk Factors—Risks Arising from Our Business—Our pursuit of investments in, and acquisitions or development of, seniors housing and healthcare assets may be unsuccessful or fail to meet our expectations" included in Item 1A of this Annual Report on Form 10-K and "Note 10—Borrowing Arrangements" of the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K.

The tenants and managers that operate our properties compete on a local and regional basis with healthcare operating companies that provide comparable services. The operators and managers of our seniors housing communities, skilled nursing facilities and hospitals compete to attract and retain residents and patients based on scope and quality of care, reputation and financial condition, price, location and physical appearance of the properties, services offered, qualified personnel, physician referrals and family preferences. The managers of our MOBs compete to attract and retain tenants based on many of the same factors, in addition to quality of the affiliated health system, physician

preferences and proximity to hospital campuses. The ability of our tenants and managers to compete successfully could be affected by private, federal and state reimbursement programs and other laws and regulations. See "Risk Factors—Risks Arising from Our Business—Our tenants, operators and managers may be adversely affected by increasing healthcare regulation and enforcement" and "—Changes in the reimbursement rates or methods of payment from third-party payors, including the Medicare and Medicaid programs, could have a material adverse effect on certain of our tenants and operators" included in Item 1A of this Annual Report on Form 10-K.

As of December 31, 2011, we had 328 employees, none of whom is subject to a collective bargaining agreement.

We maintain and/or require in our lease, management and other agreements that our tenants, operators and managers maintain all applicable lines of insurance on our properties and their operations. We believe that the amount and scope of insurance coverage provided by our policies and the policies maintained by our tenants, operators and managers are customary for similarly situated companies in our industry. Although we believe that our tenants, operators and managers are in compliance with their respective insurance requirements, we cannot provide any assurance that they will maintain the required insurance coverages, and the failure by any of them to do so could have a Material Adverse Effect on us. We also cannot provide any assurance that we will continue to require the same levels of insurance coverage under our lease, management and other agreements, that such insurance will be available at a reasonable cost in the future or that the insurance coverage provided will fully cover all losses on our properties upon the occurrence of a catastrophic event, nor can we make any guaranty as to the future financial viability of the insurers.

We maintain property and casualty insurance for our senior living operations, and we maintain general and professional liability insurance for our seniors housing communities and related operations managed by Atria. The general and professional liability insurance for our seniors housing communities and related operations managed by Sunrise is currently maintained by Sunrise in accordance with the standards contained in our management agreements. Under our management agreements with Sunrise, we may elect, on an annual basis, whether we or Sunrise will bear responsibility for maintaining the required insurance coverage for the applicable properties, but the costs of such insurance are facility expenses paid from the revenues of those properties, regardless of who maintains the insurance.

As part of our MOB development business, we provide engineering, construction and architectural services, and any design, construction or systems failures related to the properties we develop could result in substantial injury or damage to clients or third parties. Any such injury or damage claims may arise in the ordinary course and may be asserted with respect to ongoing or completed projects. Although we maintain liability insurance to protect us against these claims, if any claim results in a loss, we cannot provide any assurance that our policy limits would be adequate to cover the loss in full. If we sustain losses in excess of our insurance coverage, we may be required to pay the difference and we could lose our investment in, and/or experience reduced profits and cash flows from, the affected MOB, which could have a Material Adverse Effect on us.

The implementation of a trust or captive by any of our tenants, operators or managers could adversely affect such person's ability to satisfy its obligations under, or otherwise comply with the terms of, its respective lease, management and other agreements with us, which could have a Material Adverse Effect on us. Likewise, if we decide to implement a captive, any large funded and unfunded professional liability expenses that we incur could have a Material Adverse Effect on us.

While the properties within our portfolio are all susceptible to many varying types of regulation, we expect that the healthcare industry, in general, will continue to face increased regulation and pressure in the areas of fraud, waste and abuse, cost control, healthcare management and provision of services, among others. A significant expansion of applicable federal, state or local laws and regulations, previously enacted or future healthcare reform, new interpretations of existing laws and regulations or changes in enforcement priorities could have a material adverse effect on certain of our operators' liquidity, financial condition and results of operations and, in turn, their ability to satisfy their contractual obligations, including making rental payments under, or otherwise complying with the terms of, their leases with us. In addition, efforts by third-party payors, such as the federal Medicare program, state Medicaid programs and private insurance carriers, including health maintenance organizations and other health plans, to impose greater discounts and more stringent cost controls upon operators (through changes in reimbursement rates and methodologies, discounted fee structures, the assumption by healthcare providers of all or a portion of the financial risk or otherwise) are expected to intensify and continue. Significant limits on the scope of services reimbursed and on reimbursement rates and fees could also have a material adverse effect on certain of our operators' liquidity, financial condition and results of operations and, in turn, their ability to satisfy their contractual obligations, including making rental payments under, and otherwise complying with the terms of, their leases with us.

Participation in the Medicare and Medicaid programs generally requires the operators of our skilled nursing facilities to be licensed on an annual or bi-annual basis and certified annually through various regulatory agencies that determine compliance with federal, state and local laws. These legal requirements relate to the quality of the nursing care provided, qualifications of the administrative personnel and nursing staff, the adequacy of the physical plant and equipment and continuing compliance with the laws and regulations governing the operation of skilled nursing facilities. The

failure of an operator to maintain or renew any required license or regulatory approval or to correct serious deficiencies identified in compliance surveys could prevent it from continuing operations at a property. A loss of licensure or certification could also adversely affect a skilled nursing facility operator's ability to receive payments from the Medicare and Medicaid programs, which, in turn, could affect adversely their ability to satisfy their contractual obligations, including making rental payments under, and otherwise complying with the terms of, their leases with us.

Similarly, in order to receive Medicare and Medicaid reimbursement, our hospitals must meet the applicable conditions of participation set forth by the U.S. Department of Health and Human Services ("HHS") relating to the type of hospital and its equipment, personnel and standard of medical care, as well as comply with state and local laws and regulations. Hospitals undergo periodic on-site licensure surveys, which generally are limited if the hospital is accredited by The Joint Commission (formerly the Joint Commission on Accreditation of Healthcare Organizations) or other recognized accreditation organizations. A loss of licensure or certification could adversely affect a hospital's ability to receive payments from the Medicare and Medicaid programs, which, in turn, could adversely affect their ability to satisfy their contractual obligations, including making rental payments under, and otherwise complying with the terms of, their leases with us.

Seniors housing communities are subject to relatively few, if any, federal regulations. Instead, to the extent they are regulated, the regulation is conducted mainly by state and local laws governing licensure, provision of services, staffing requirements and other operational matters. These laws vary greatly from one jurisdiction to another. Although recent growth in the U.S. seniors housing industry has attracted the attention of various federal agencies that believe more federal regulation of these properties is necessary, thus far, Congress has deferred to state regulation of seniors housing communities. However, as a result of this growth and increased federal scrutiny, some states have revised and strengthened their regulation of seniors housing communities, and more states are expected to do the same in the future.

Skilled nursing facilities and hospitals are subject to various state CON laws requiring governmental approval prior to the development or expansion of healthcare facilities and services. The approval process in these states generally requires a facility to demonstrate the need for additional or expanded healthcare facilities or services. CONs, where applicable, are also sometimes necessary for changes in ownership or control of licensed facilities, addition of beds, investment in major capital equipment, introduction of new services or termination of services previously approved through the CON process. CON laws and regulations may restrict an operator's ability to expand our properties and grow its business in certain circumstances, which could have an adverse effect on the operator's revenues and, in turn, its ability to make rental payments under, and otherwise comply with the terms of, its leases with us. In addition, in the event that any operator of our properties fails to make rental payments to us or to comply with applicable healthcare regulations, our ability to evict that operator and substitute another operator for a particular facility may be materially delayed or limited by CON laws, as well as by various state licensing and receivership laws and Medicare and Medicaid change-of-ownership rules. Such delays and limitations could have a material adverse effect on our ability to collect rent, to obtain possession of leased properties, or otherwise to exercise remedies for tenant default. We may also incur substantial additional expenses in connection with any such licensing, receivership or change-of-ownership proceedings.

Various federal and state laws and regulations prohibit a wide variety of fraud and abuse by healthcare providers who participate in, receive payments from or make or receive referrals for work in

connection with government-funded healthcare programs, including Medicare and Medicaid. The federal laws include, by way of example, the following:

Sanctions for violating these federal laws include criminal and civil penalties such as punitive sanctions, damage assessments, monetary penalties, imprisonment, denial of Medicare and Medicaid payments, and/or exclusion from the Medicare and Medicaid programs. These laws also impose an affirmative duty on operators to ensure that they do not employ or contract with persons excluded from the Medicare and other government programs.

Many states have adopted or are considering legislative proposals similar to the federal anti-fraud and abuse laws, some of which extend beyond the Medicare and Medicaid programs, to prohibit the payment or receipt of remuneration for the referral of patients and physician self-referrals, regardless of whether the service was reimbursed by Medicare or Medicaid. Many states have also adopted or are considering legislative proposals to increase patient protections, such as minimum staffing levels, criminal background checks, and limiting the use and disclosure of patient specific health information. These state laws also impose criminal and civil penalties similar to the federal laws.

In the ordinary course of their business, the operators of our properties have been and are subject regularly to inquiries, investigations and audits by federal and state agencies that oversee applicable laws and regulations. Increased funding through recent federal and state legislation has led to significant growth in the number of investigations and enforcement actions over the past several years. Private enforcement of healthcare fraud has also increased, due in large part to amendments to the civil False Claims Act in 1986 that were designed to encourage private individuals to sue on behalf of the government. These whistleblower suits by private individuals, known as qui tam suits, may be filed by almost anyone, including present and former patients or nurses and other employees. HIPAA also created a series of new healthcare crimes.

As federal and state budget pressures persist, administrative agencies may continue to escalate their investigation and enforcement efforts to eliminate waste and to control fraud and abuse in governmental healthcare programs. A violation of any federal or state anti-fraud and abuse laws or regulations by an operator of our properties could have a material adverse effect on the operator's liquidity, financial condition or results of operations, which could adversely affect its ability to satisfy its

contractual obligations, including making rental payments under, and otherwise complying with the terms of, its leases and other agreements with us.

In March 2010, President Obama signed into law the Patient Protection and Affordable Care Act, along with a reconciliation measure, the Health Care and Education Reconciliation Act of 2010 (collectively, the "Affordable Care Act"). The passage of the Affordable Care Act has resulted in comprehensive reform legislation that is expected to expand health care coverage to millions of currently uninsured people beginning in 2014. To help fund this expansion, the Affordable Care Act outlines certain reductions in Medicare reimbursement rates for various healthcare providers, including long-term acute care hospitals and skilled nursing facilities, as well as certain other changes to Medicare payment methodologies.

The Affordable Care Act, among other things, reduced the inflationary market basket increase included in standard federal payment rates for long-term acute care hospitals by 25 basis points in fiscal year 2010, 50 basis points in fiscal year 2011, 10 basis points in fiscal years 2012 and 2013, 30 basis points in fiscal year 2014, 20 basis points in fiscal years 2015 and 2016, and 75 basis points in fiscal years 2017 through 2019. In addition, under the Affordable Care Act, long-term acute care hospitals and skilled nursing facilities are subject to a rate adjustment to the market basket increase, beginning in fiscal year 2012, to reflect improvements in productivity. The constitutionality of various provisions of the Affordable Care Act is being considered by the U.S. Supreme Court. In addition to the constitutionality of the so-called individual mandate, the U.S. Supreme Court is considering the constitutionality of provisions that expand Medicaid coverage to include individuals who would otherwise not be eligible and whether those provisions, if declared unconstitutional, can be severed from the rest of the Affordable Care Act. Oral argument on these matters has been scheduled for March 2012 with a decision likely by the end of June 2012.

Healthcare is one of the largest industries in the United States and continues to attract a great deal of legislative interest and public attention. We cannot provide any assurance that previously enacted or future healthcare reform legislation or changes in the administration or implementation of governmental and non-governmental healthcare reimbursement programs will not have a material adverse effect on our operators' liquidity, financial condition or results of operations, or on their ability to satisfy their obligations to us, which, in turn, could have a Material Adverse Effect on us.

The Balanced Budget Act of 1997 ("BBA") mandated the creation of a prospective payment system for long-term acute care hospitals ("LTAC PPS") for cost reporting periods commencing on or after October 1, 2002. Under LTAC PPS, which classifies patients into distinct diagnostic groups based on clinical characteristics and expected resource needs, long-term acute care hospitals are reimbursed on a predetermined rate, rather than on a reasonable cost basis that reflects costs incurred. LTAC PPS requires payment for a Medicare beneficiary at a predetermined, per discharge amount for each defined patient category (called "Long-Term Care—Diagnosis Related Groups" or "LTC-DRGs"), adjusted for differences in area wage levels.

Updates to LTAC PPS payment rates are established by regulators and published annually for the long-term acute care hospital rate year, which coincides with annual updates to the LTC-DRG classification system and corresponds to the federal fiscal year (October 1 through September 30).

The Medicare, Medicaid, and SCHIP Extension Act of 2007 (Pub. L. No. 110-173) (the "Medicare Extension Act") significantly expanded medical necessity reviews by the Centers for Medicare & Medicaid Services ("CMS") by requiring long-term acute care hospitals to institute a patient review process to better assess patients upon admission and on a continuing basis for appropriateness of care.

In addition, the Medicare Extension Act, among other things, provided the following long-term acute care hospital payment policy changes, all of which were extended for two years by the Affordable Care Act:

Lastly, the Medicare Extension Act introduced a moratorium on new long-term acute care hospitals and beds for three years.

In a final rule published in May 2008, CMS delayed the extension of the 25-percent rule to freestanding and grandfathered long-term acute care hospitals and increased the patient percentage thresholds for certain urban and rural long-term acute care "hospitals-within-hospitals" and "satellite" facilities for three years, as mandated by the Medicare Extension Act. The rule also set forth policies on implementing the moratorium on new long-term acute care hospitals and beds imposed by the Medicare Extension Act.

In a final rule published in August 2009, CMS finalized policies to implement changes required by Section 124 of the Medicare Improvements for Patients & Providers Act of 2008 (Pub. L. No. 110-275), continuing reforms intended to improve the accuracy of Medicare payments for inpatient acute care through the severity-adjusted diagnosis-related group (MS-LTC-DRG) classification system for long-term acute care hospitals.

On August 18, 2011, CMS published its final rule updating LTAC PPS for the 2012 fiscal year (October 1, 2011 through September 30, 2012). Under the rule, the LTAC PPS standard federal payment rate will increase by 1.8% in fiscal year 2012, reflecting a 2.9% increase in the market basket index, less a 1% productivity adjustment and the additional 10 basis point reduction required by the Affordable Care Act. As a result, CMS estimates that net payments to long-term acute care hospitals in fiscal year 2012 under the final rule will increase relative to fiscal year 2011 by approximately $126 million, or 2.5%, due to area wage adjustments, as well as increases in high-cost and short-stay outlier payments and other policies adopted in the final rule.

In addition, as a result of the enactment of the Budget Control Act of 2011 and subsequent events, which are discussed below, Medicare payments to long-term acute care hospitals will be reduced by 2% on January 2, 2013.

We regularly assess the financial implications of CMS's rules on the operators of our long-term acute care hospitals, but we cannot provide any assurance that the current rules or future updates to LTAC PPS, LTC-DRGs or Medicare reimbursement for long-term acute care hospitals will not materially adversely affect our operators, which, in turn, could have a Material Adverse Effect on us. See "Risk Factors—Risks Arising from Our Business—Changes in the reimbursement rates or methods of payment from third-party payors, including the Medicare and Medicaid programs, could have a material adverse effect on certain of our tenants and operators" included in Item 1A of this Annual Report on Form 10-K.

The BBA also mandated the creation of a prospective payment system for skilled nursing facilities ("SNF PPS") offering Part A covered services. Under SNF PPS, payment amounts are based upon classifications determined through assessments of individual Medicare patients in the skilled nursing facility, rather than on the facility's reasonable costs. SNF PPS payments are made on a per diem basis for each resident and are generally intended to cover all inpatient services for Medicare patients, including routine nursing care, most capital-related costs associated with the inpatient stay, and ancillary services, such as respiratory therapy, occupational and physical therapy, speech therapy and certain covered drugs.

In response to widespread healthcare industry concern about the reductions in payments under the BBA, the federal government enacted the Balanced Budget Refinement Act of 1999 ("BBRA"). The BBRA increased the per diem reimbursement rates for certain high acuity patients by 20% from April 1, 2000 until case mix refinements were implemented by CMS, as explained below. The BBRA also imposed a two-year moratorium on the annual cap mandated by the BBA on physical, occupational and speech therapy services provided to a patient by outpatient rehabilitation therapy providers, including Part B covered therapy services in nursing facilities. Relief from the BBA therapy caps was subsequently extended multiple times by Congress, but these extensions expired on December 31, 2009 and have not been renewed by Congress.

Pursuant to its final rule updating SNF PPS for the 2006 fiscal year, CMS refined the resource utilization groups ("RUGs") used to determine the daily payment for beneficiaries in skilled nursing facilities by adding nine new payment categories, the result of which was to eliminate the temporary add-on payments that Congress enacted as part of the BBRA.

Under its final rule updating LTC-DRGs for the 2007 fiscal year, CMS reduced reimbursement of uncollectible Medicare coinsurance amounts for all beneficiaries (other than beneficiaries of both Medicare and Medicaid) from 100% to 70% for skilled nursing facility cost reporting periods beginning on or after October 1, 2005. The rule also included various options for classifying and weighting patients transferred to a skilled nursing facility after a hospital stay less than the mean length of stay associated with that particular diagnosis-related group.

Under its final rule updating SNF PPS for the 2010 fiscal year, CMS recalibrated the case-mix indexes for RUGs used to determine the daily payment for beneficiaries in skilled nursing facilities and implemented the RUG-IV classification model for skilled nursing facilities for the 2011 fiscal year. However, the Affordable Care Act delayed the implementation of RUG-IV for one year, and CMS subsequently modified the implementation schedule in its notice updating SNF PPS for the 2011 fiscal year.

In November 2010, CMS placed on public display its final Medicare Physician Fee Schedule rule for the 2011 calendar year, which set a $1,870 cap on physical therapy and speech-language pathology services and a separate $1,870 cap on occupational therapy services, including therapy provided in skilled nursing facilities, both without an exceptions process. In December 2010, the Medicare and Medicaid Extenders Act of 2010 (Pub. L. No. 111 309) was enacted to lift the caps on therapy services and continue the exceptions process.

On August 8, 2011, CMS published its final rule updating SNF PPS for the 2012 fiscal year (October 1, 2011 through September 30, 2012). Under the rule, the update to the SNF PPS standard federal payment rate includes a 2.7% increase in the market basket index, less a 1.0% productivity adjustment mandated by the Affordable Care Act and a 12.6% "parity adjustment recalibration" to account for estimated overpayments under the RUG-IV classification model, resulting in a net 11.1% decrease in the SNF PPS standard federal payment rate for fiscal year 2012. The rule also requires group therapy to be treated in the same manner as concurrent therapy (i.e., allocating therapy minutes

among the group's patients, rather than counting the same minutes for each patient), which may additionally affect net payments to skilled nursing facilities. CMS estimates that net payments to skilled nursing facilities as a result of the final rule will decrease by approximately $3.87 billion in fiscal year 2012, but stated that "Even with the recalibration, the FY 2012 payment rates will be 3.4 percent higher than the rates established for FY 2010, the period immediately preceding the unintended spike in payment levels."

In addition, as a result of the enactment of the Budget Control Act of 2011 and subsequent events, which are discussed below, Medicare payments to skilled nursing facilities will be reduced by 2% on January 2, 2013.

We regularly assess the financial implications of CMS's rules on the operators of our skilled nursing facilities, but we cannot provide any assurance that the current rules or future updates to SNF PPS, therapy services or Medicare reimbursement for skilled nursing facilities will not materially adversely affect our operators, which, in turn, could have a Material Adverse Effect on us. See "Risk Factors—Risks Arising from Our Business—Changes in the reimbursement rates or methods of payment from third-party payors, including the Medicare and Medicaid programs, could have a material adverse effect on certain of our tenants and operators" included in Item 1A of this Annual Report on Form 10-K.

Approximately two-thirds of all nursing home residents are dependent on Medicaid. Medicaid reimbursement rates, however, typically are less than the amounts charged by the operators of our skilled nursing facilities. Although the federal government and the states share responsibility for financing Medicaid, states have a wide range of discretion, within certain federal guidelines, to determine eligibility and reimbursement methodology. In addition, federal legislation limits an operator's ability to withdraw from the Medicaid program by restricting the eviction or transfer of Medicaid residents. As state budget pressures continue to escalate and in an effort to address actual or potential budget shortfalls, many state legislatures have enacted or proposed reductions to Medicaid expenditures by implementing "freezes" or cuts in Medicaid rates paid to providers, including hospitals and skilled nursing facilities, or by restricting eligibility and benefits.

In the Deficit Reduction Act of 2005 (Pub. L. No. 109 171), Congress made changes to the Medicaid program that were estimated to result in $10 billion in savings to the federal government over the five years following enactment of the legislation, primarily through the accounting practices some states use to calculate their matched payments and revising the qualifications for individuals who are eligible for Medicaid benefits. The changes made by CMS's final rule updating SNF PPS for the 2006 fiscal year were also anticipated to reduce Medicaid payments to skilled nursing facility operators, and as part of the Tax Relief and Health Care Act of 2006 (Pub. L. No. 109-432), Congress reduced the ceiling on taxes that states may impose on healthcare providers and that would qualify for federal financial participation under Medicaid by 0.5%, from 6% to 5.5%, until October 1, 2011. While it was anticipated that this reduction would have a negligible effect, impacting only those states with taxes in excess of 5.5%, we have not ascertained its financial implications on our skilled nursing facility operators.

In contrast, the American Recovery and Reinvestment Act of 2009 (Pub. L. No. 111-5) (the "Recovery Act"), temporarily increased federal payments to state Medicaid programs by $86.6 billion through, among other things, a 6.2% increase in the federal share of Medicaid expenditures across the board, with additional funds available depending on a state's federal medical assistance percentage and unemployment rate. Though the Medicaid federal assistance payments were originally expected to expire on December 31, 2010, the President's fiscal year 2011 budget extended those payments through June 30, 2011. The Recovery Act also requires states to promptly pay nursing facilities under their Medicaid program, and precludes states, as a condition of receiving the additional funding, from heightening their Medicaid eligibility requirements.

We expect more states to adopt significant Medicaid rate freezes or cuts or other program changes as their reimbursement methodologies continue to evolve. In addition, the U.S. government may revoke, reduce or stop approving "provider taxes" that have the effect of increasing Medicaid payments to the states. We cannot predict what impact these actions would have on the operators of our skilled nursing facilities, and we cannot provide any assurance that payments under Medicaid are now or in the future will be sufficient to fully reimburse those operators for the cost of providing skilled nursing services. Severe and widespread Medicaid rate cuts or freezes could materially adversely affect our skilled nursing facility operators, which, in turn, could adversely affect their ability to satisfy their contractual obligations, including making rental payments under, and otherwise complying with the terms of, their leases with us.

On August 2, 2011, President Obama and the U.S. Congress enacted the Budget Control Act of 2011 to increase the federal government's borrowing authority (the so-called "debt ceiling") and reduce the federal government's projected operating deficit. To implement this legislation, President Obama and members of the U.S. Congress have proposed various spending cuts and tax reform initiatives, some of which could result in changes (including substantial reductions in funding) to Medicare, Medicaid or Medicare Advantage Plans. Under the agreement reached to allow the federal government to raise the debt ceiling in August, a twelve-member, bipartisan committee was given a deadline of November 23, 2011 to develop recommendations for reducing the federal budget deficit by a total of at least $1.2 trillion over ten years. However, the committee was not able to agree on a plan and, therefore, $1.2 trillion in automatic spending cuts, including a 2% reduction in Medicare payments to long-term acute care hospitals and skilled nursing facilities, as noted above, are expected to go into effect on January 2, 2013. These measures and any future federal legislation relating to the debt ceiling or deficit reduction could have a material adverse effect on our operators' liquidity, financial condition or results of operations, which could adversely affect their ability to satisfy their obligations to us and which, in turn, could have a Material Adverse Effect on us.

As an owner of real property, we are subject to various federal, state and local laws and regulations regarding environmental, health and safety matters. These laws and regulations address, among other things, asbestos, polychlorinated biphenyls, fuel oil management, wastewater discharges, air emissions, radioactive materials, medical wastes, and hazardous wastes, and in certain cases, the costs of complying with these laws and regulations and the penalties for non-compliance can be substantial. Even with respect to properties that we do not operate or manage, we may be held primarily or jointly and severally liable for costs relating to the investigation and clean-up of any property from which there is or has been an actual or threatened release of a regulated material and any other affected properties, regardless of whether we knew of or caused the release. Such costs typically are not limited by law or regulation and could exceed the property's value. In addition, we may be liable for certain other costs, such as governmental fines and injuries to persons, property or

natural resources, as a result of any such actual or threatened release. See "Risk Factors—Risks Arising from Our Business—If any of our properties are found to be contaminated, or if we become involved in any environmental disputes, we could incur substantial liabilities and costs" included in Item 1A of this Annual Report on Form 10-K.

Under the terms of our lease and management agreements, we generally have a right to indemnification by the tenants, operators and managers of our properties for any contamination caused by them. However, we cannot provide any assurance that our tenants, operators and managers will have the financial capability or willingness to satisfy their respective indemnification obligations to us, and any such inability or unwillingness to do so may require us to satisfy the underlying environmental claims. See "Risk Factors—Risks Arising from Our Business—We depend on Kindred and Brookdale Senior Living for a significant portion of our revenues and operating income; Any inability or unwillingness by Kindred or Brookdale Senior Living to satisfy its obligations under its agreements with us could have a Material Adverse Effect on us" included in Item 1A of this Annual Report on Form 10-K.

In general, we have also agreed to indemnify our tenants against any environmental claims (including penalties and clean-up costs) resulting from any condition arising in, on or under, or relating to, the leased properties at any time before the applicable lease commencement date. With respect to our senior living operating portfolio, we have agreed to indemnify our managers against any environmental claims (including penalties and clean-up costs) resulting from any condition on those properties, unless the manager caused or contributed to that condition.

We did not make any material capital expenditures in connection with environmental, health, and safety laws, ordinances and regulations in 2011 and do not expect that we will be required to make any such material capital expenditures during 2012.

The following discussion summarizes certain U.S. federal income tax considerations that you may deem relevant as a holder of our common stock. It is not tax advice, nor does it purport to address all aspects of U.S. federal income taxation that may be important to particular stockholders in light of their personal circumstances or to certain types of stockholders that may be subject to special rules, such as insurance companies, tax-exempt organizations (except to the extent discussed below under "—Treatment of Tax-Exempt Stockholders"), financial institutions, pass-through entities (or investors in such entities) or broker-dealers, and non-U.S. individuals and entities (except to the extent discussed below under "—Special Tax Considerations for Non-U.S. Stockholders").

The statements in this section are based on the Internal Revenue Code of 1986, as amended (the "Code"), U.S. Treasury Regulations and administrative and judicial interpretations thereof. The laws governing the U.S. federal income tax treatment of REITs and their stockholders are highly technical and complex, and this discussion is qualified in its entirety by the authorities listed above, as in effect on the date hereof. We cannot provide any assurance that new laws, interpretations of law or court decisions, any of which may take effect retroactively, will not cause any statement herein to be inaccurate.

We elected REIT status beginning with the year ended December 31, 1999. Beginning with the 1999 tax year, we believe that we have satisfied the requirements to qualify as a REIT, and we intend to continue to qualify as a REIT for federal income tax purposes. If we continue to qualify for taxation as a REIT, we generally will not be subject to federal income tax on net income that we currently distribute to stockholders. This treatment substantially eliminates the "double taxation" (i.e., taxation at both the corporate and stockholder levels) that generally results from investment in a corporation.

Notwithstanding such qualification, we will be subject to federal income tax on any undistributed taxable income, including undistributed net capital gains, at regular corporate rates. In addition, we will be subject to a 4% excise tax if we do not satisfy specific REIT distribution requirements. See "—Requirements for Qualification as a REIT—Annual Distribution Requirements." Under certain circumstances, we may be subject to the "alternative minimum tax" on our undistributed items of tax preference. If we have net income from the sale or other disposition of "foreclosure property" (see below) held primarily for sale to customers in the ordinary course of business or certain other non-qualifying income from foreclosure property, we will be subject to tax at the highest corporate rate on that income. See "—Requirements for Qualification as a REIT—Asset Tests." In addition, if we have net income from "prohibited transactions" (which are, in general, certain sales or other dispositions of property (other than foreclosure property) held primarily for sale to customers in the ordinary course of business), that income will be subject to a 100% tax.

We may also be subject to "Built-in Gains Tax" on any appreciated asset that we own or acquire that was previously owned by a C corporation (i.e., a corporation generally subject to full corporate-level tax). If we dispose of any such asset and recognize gain on the disposition during the ten-year period immediately after the asset was owned by a C corporation (either prior to our REIT election, or through stock acquisition or merger), then we generally will be subject to regular corporate income tax on the gain equal to the lesser of the recognized gain at the time of disposition or the built-in gain in that asset as of the date it became a REIT asset.

In addition, if we fail to satisfy either of the gross income tests for qualification as a REIT (as discussed below), but still maintain such qualification under the relief provisions of the Code, we will be subject to a 100% tax on the gross income attributable to the amount by which we failed the applicable test, multiplied by a fraction intended to reflect our profitability. If we violate one or more of the REIT asset tests (as discussed below), we may avoid a loss of our REIT status if we qualify under certain relief provisions and, among other things, pay a tax equal to the greater of $50,000 or the highest corporate tax rate multiplied by the net income generated by the non-qualifying asset during a specified period. If we fail to satisfy any requirement for REIT qualification, other than the gross income or assets tests mentioned above, but nonetheless maintain such qualification by meeting certain other requirements, we may be subject to a $50,000 penalty for each failure. Finally, we will incur a 100% excise tax on the income derived from certain transactions with a taxable REIT subsidiary (including rental income derived from leasing properties to a taxable REIT subsidiary) that are not conducted on an arm's-length basis.

See "—Requirements for Qualification as a REIT" below for other circumstances in which we may be required to pay federal taxes.

To qualify as a REIT, we must meet the requirements discussed below relating to our organization, sources of income, nature of assets and distributions of income to stockholders.

The Code defines a REIT as a corporation, trust or association: (i) that is managed by one or more directors or trustees; (ii) the beneficial ownership of which is evidenced by transferable shares or by transferable certificates of beneficial interest; (iii) that would be taxable as a domestic corporation but for Sections 856 through 859 of the Code; (iv) that is neither a financial institution nor an insurance company subject to certain provisions of the Code; (v) the beneficial ownership of which is held by 100 or more persons during at least 335 days of a taxable year of twelve months, or during a proportionate part of a shorter taxable year (the "100 Shareholder Rule"); (vi) not more than 50% in value of the outstanding stock of which is owned, directly or indirectly, by five or fewer individuals (as

defined in the Code to include certain entities) during the last half of each taxable year (the "5/50 Rule"); (vii) that makes an election to be a REIT (or has made such election for a previous taxable year) and satisfies all relevant filing and other administrative requirements established by the Internal Revenue Service ("IRS") that must be met in order to elect and to maintain REIT status; (viii) that uses a calendar year for federal income tax purposes; and (ix) that meets certain other tests, described below, regarding the nature of its income and assets.

We believe but cannot provide any assurance that we have satisfied and will continue to satisfy the organizational requirements for qualification as a REIT. Our certificate of incorporation contains certain restrictions on the transfer of our shares that are intended to prevent a concentration of ownership of our stock that would cause us to fail the 5/50 Rule or the 100 Shareholder Rule; however, we cannot provide any assurance as to the effectiveness of these restrictions.

In addition, to qualify as a REIT, a corporation may not have (as of the end of the taxable year) any earnings and profits that were accumulated in periods before it elected REIT status or that are from acquired non-REIT corporations. We believe that we have not had any accumulated earnings and profits that are attributable to non-REIT periods or from acquired corporations that were not REITs, although the IRS is entitled to challenge that determination.

We believe but cannot provide any assurance that we have been and will continue to be in compliance with the gross income tests described above. If we fail to satisfy one or both gross income tests for any taxable year, we may nevertheless qualify as a REIT for that year if we qualify under certain relief provisions of the Code, in which case we would be subject to a 100% tax on the income exceeding one or both of the gross income tests. If we fail to satisfy one or both of the gross income tests and do not qualify under the relief provisions for any taxable year, we will not qualify as a REIT for that year, which would have a Material Adverse Effect on us.

At the close of each quarter of our taxable year, we must satisfy the following tests relating to the nature of our assets:

In addition, no more than 25% of the value of our assets (20% for taxable years beginning prior to 2009) can be represented by securities of taxable REIT subsidiaries (the "25% TRS test").

We believe but cannot provide any assurance that we have been and will continue to be in compliance with the asset tests described above. If we fail to satisfy the asset tests at the end of any quarter, we may nevertheless continue to qualify as a REIT if we satisfied all of the asset tests at the close of the preceding calendar quarter and the discrepancy between the value of our assets and the asset test requirements is due to changes in the market values of our assets and not caused in any part by an acquisition of non-qualifying assets.

Furthermore, if we fail to satisfy any of the asset tests at the end of any calendar quarter without curing such failure within 30 days after the end of such quarter, we would fail to qualify as a REIT unless we qualified under certain relief provisions enacted as part of the American Jobs Creation Act of 2004. Under one relief provision, we would continue to qualify as a REIT if our failure to satisfy the 5% asset test, the 10% voting securities test or the 10% value test is due to the ownership of assets having a total value not exceeding the lesser of 1% of our assets at the end of the relevant quarter or $10 million and we disposed of such assets (or otherwise met such asset tests) within six months after the end of the quarter in which the failure was identified. If we fail to satisfy any of the asset tests for a particular quarter but do not qualify under the relief provision described in the preceding sentence, then we would be deemed to have satisfied the relevant asset test if: (i) following identification of the failure, we filed a schedule with a description of each asset that caused the failure; (ii) the failure is due to reasonable cause and not willful neglect; (iii) we disposed of the non-qualifying asset (or otherwise met the relevant asset test) within six months after the end of the quarter in which the failure was identified; and (iv) we paid a penalty tax equal to the greater of $50,000 or the highest corporate tax rate multiplied by the net income generated by the non-qualifying asset during the period beginning on the first date of the failure and ending on the date we disposed of the asset (or otherwise cured the asset test failure). We cannot predict, however, whether in all circumstances we would be entitled to the benefit of these relief provisions. If we fail to satisfy any of the asset tests and do not qualify for the relief provisions, we will lose our REIT status, which would have a Material Adverse Effect on us.

The foreclosure property rules permit us (by our election) to foreclose or repossess properties without being disqualified as a REIT as a result of receiving income that does not qualify under the gross income tests. However, in that case, we would be subject to a corporate tax on the net non-qualifying income from "foreclosure property," and the after-tax amount would increase the dividends we would be required to distribute to stockholders. See "—Annual Distribution Requirements" below. The corporate tax imposed on non-qualifying income would not apply to income that does qualify as "good REIT income," such as a lease of qualified healthcare property to a taxable REIT subsidiary, where the taxable REIT subsidiary engages an eligible independent contractor to manage and operate the property.

Foreclosure property treatment will end on the first day on which we enter into a lease of the applicable property that will give rise to income that does not constitute "good REIT income" under Section 856(c)(3) of the Code, but such treatment will not end if the lease will only give rise to "good REIT income." In addition, foreclosure property treatment will end if any construction takes place on the property (other than completion of a building or other improvement more than 10% complete before default became imminent). Foreclosure property treatment (other than for qualified healthcare property) is available for an initial period of three years and may, in certain circumstances, be extended for an additional three years. Foreclosure property treatment for qualified healthcare property is available for an initial period of two years and may, in certain circumstances, be extended for an additional four years.

A taxable REIT subsidiary, or "TRS," is a corporation subject to tax as a regular C corporation. Generally, a TRS can own assets that cannot be owned by a REIT and can perform tenant services (excluding the direct or indirect operation or management of a lodging or healthcare facility) that would otherwise disqualify the REIT's rental income under the gross income tests. Also, notwithstanding general restrictions on related party rent, a REIT can lease healthcare properties to a TRS if the TRS does not manage or operate the healthcare facilities and instead engages an "eligible independent contractor" to manage the healthcare facilities. We are permitted to own up to 100% of a TRS, subject to the 25% TRS test, but there are certain limits on the ability of a TRS to deduct interest payments made to us. In addition, we are subject to a 100% penalty tax on any excess payments that we receive or any excess expenses deducted by the TRS if the economic arrangements between the REIT, the REIT's tenants and the TRS are not comparable to similar arrangements among unrelated parties.

In order to be taxed as a REIT, we are required to distribute dividends (other than capital gain dividends) to our stockholders in an amount at least equal to the sum of (i) 90% of our "REIT taxable income" (computed without regard to the dividends paid deduction and our net capital gain) and (ii) 90% of the net income (after tax), if any, from foreclosure property, minus the sum of certain items of non-cash income. These dividends must be paid in the taxable year to which they relate, or in the following taxable year if (i) they are declared in October, November or December, payable to stockholders of record on a specified date in any one of those months and actually paid during January of such following year or (ii) they are declared before we timely file our tax return for such year and paid on or before the first regular dividend payment after such declaration, and we elect on our federal income tax return for the prior year to have a specified amount of the subsequent dividend treated as paid in the prior year. To the extent we do not distribute all of our net capital gain or at least 90%, but less than 100%, of our "REIT taxable income," as adjusted, we will be subject to tax on the undistributed amount at regular capital gains and ordinary corporate tax rates except to the extent of our net operating loss or capital loss carryforwards. If we pay any Built-in Gains Taxes, those taxes will be deductible in computing REIT taxable income. Moreover, if we fail to distribute during each calendar year (or, in the case of distributions with declaration and record dates falling in the last three months of the calendar year, by the end of January following such calendar year) at least the sum of 85% of our REIT ordinary income for such year, 95% of our REIT capital gain net income for such year (other than long-term capital gain we elect to retain and treat as having been distributed to stockholders), and any undistributed taxable income from prior periods, we will be subject to a 4% nondeductible excise tax on the excess of such required distribution over the amounts actually distributed.

We believe but cannot provide any assurance that we have satisfied the annual distribution requirements for the year of our initial REIT election and each year thereafter through the year ended December 31, 2011. Although we intend to satisfy the annual distribution requirements to continue to qualify as a REIT for the year ending December 31, 2012 and subsequent years, economic, market, legal, tax or other considerations could limit our ability to meet those requirements.

In Revenue Procedure 2010-12, the IRS stated that it would treat stock dividends as distributions for purposes of satisfying the REIT distribution requirements for calendar years 2008 through 2012, provided that stockholders can elect to receive the distribution in either cash or stock, subject to certain limitations. Any stock so distributed would be taxable to the recipient. We may choose to declare stock dividends in accordance with Revenue Procedure 2010-12 or otherwise. We also have net operating loss carryforwards that we can use to reduce our annual distribution requirements. See "Note 13—Income Taxes" of the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K.

If we fail to satisfy one or more requirements for REIT qualification, other than by violating a gross income or asset test for which relief is otherwise available as described above, we would retain our REIT qualification if the failure is due to reasonable cause and not willful neglect and if we pay a penalty of $50,000 for each such failure. We cannot predict, however, whether in all circumstances we would be entitled to the benefit of this relief provision.

If our election to be taxed as a REIT is revoked or terminated (e.g., due to a failure to meet the REIT qualification tests without qualifying for any applicable relief provisions), we would be subject to tax (including any applicable alternative minimum tax) on our taxable income at regular corporate rates (for all open tax years beginning with the year our REIT election is revoked or terminated), and distributions to stockholders would not be deductible by us, nor would they be required to be made. To the extent of current and accumulated earnings and profits, all distributions to stockholders would be taxable as ordinary income (except to the extent such dividends are eligible for the qualified dividends rate generally available to non-corporate holders), and, subject to certain limitations in the Code, corporate stockholders may be eligible for the dividends received deduction. In addition, we would be prohibited from re-electing REIT status for the four taxable years following the year during which we ceased to qualify as a REIT, unless certain relief provisions of the Code applied. We cannot predict, however, whether we would be entitled to such relief.

As used herein, the term "U.S. Stockholder" refers to any beneficial owner of our common stock that is, for U.S. federal income tax purposes, an individual who is a citizen or resident of the United States, a corporation 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 includible in gross income for U.S. federal income tax purposes regardless of its source, or a trust if (i) a U.S. court is able to exercise primary supervision over the administration of such trust and one or more U.S. persons have authority to control all substantial decisions of the trust or (ii) the trust has elected under applicable U.S. Treasury Regulations to retain its pre-August 20, 1996 classification as a U.S. person. If an entity treated as a partnership for U.S. federal income tax purposes holds our common stock, the tax treatment of a partner in the partnership will generally depend on the status of the partner and the activities of the partnership. Partners of partnerships holding our stock should consult their tax advisors. This section assumes the U.S. Stockholder holds our common stock as a capital asset.

As long as we qualify as a REIT, distributions made to our taxable U.S. Stockholders out of current or accumulated earnings and profits (and not designated as capital gain dividends) generally

will be taxable to such U.S. Stockholders as ordinary income and will not be eligible for the qualified dividends rate generally available to non-corporate holders or for the dividends received deduction generally available to corporations. Distributions that are designated as capital gain dividends will be taxed as a long-term capital gain (to the extent such distributions do not exceed our actual net capital gain for the taxable year) without regard to the period for which the stockholder has held its shares. Distributions in excess of current and accumulated earnings and profits will not be taxable to a U.S. Stockholder to the extent they do not exceed the adjusted basis of the stockholder's shares (determined on a share-by-share basis), but rather will reduce the adjusted basis of those shares. To the extent that distributions in excess of current and accumulated earnings and profits exceed the adjusted basis of a stockholder's shares, such distributions will be included in income as capital gains. The tax rate applicable to such capital gains will depend on the stockholder's holding period for the shares. Any distribution declared by us and payable to a stockholder of record on a specified date in October, November or December of any year will be treated as both paid by us and received by the stockholder on December 31 of that year, provided that we actually pay the distribution during January of the following calendar year.

We may elect to treat all or a part of our undistributed net capital gain as if it had been distributed to our stockholders. If we make such an election, our stockholders would be required to include in their income as long-term capital gain their proportionate share of our undistributed net capital gain, as designated by us. Each such stockholder would be deemed to have paid its proportionate share of the income tax imposed on us with respect to such undistributed net capital gain, and this amount would be credited or refunded to the stockholder. In addition, the tax basis of the stockholder's shares would be increased by its proportionate share of undistributed net capital gains included in its income, less its proportionate share of the income tax imposed on us with respect to such gains.

Stockholders may not include in their individual income tax returns any of our net operating losses or net capital losses. Instead, we would carry over those losses for potential offset against our future income, subject to certain limitations. Taxable distributions from us and gain from the disposition of our common stock will not be treated as passive activity income, and, therefore, stockholders generally will not be able to apply any "passive activity losses" (such as losses from certain types of limited partnerships in which the stockholder is a limited partner) against such income. In addition, taxable distributions from us generally will be treated as investment income for purposes of the investment interest limitations.

We will notify stockholders after the close of our taxable year as to the portions of the distributions attributable to that year that constitute ordinary income, return of capital and capital gain. To the extent a portion of the distribution is designated as a capital gain dividend, we will notify stockholders as to the portion that is a "15% rate gain distribution" and the portion that is an unrecaptured Section 1250 distribution. A 15% rate gain distribution is a capital gain distribution to domestic stockholders that are individuals, estates or trusts that is taxable at a maximum rate of 15%. An unrecaptured Section 1250 gain distribution would be taxable to taxable domestic stockholders that are individuals, estates or trusts at a maximum rate of 25%.

In general, a U.S. Stockholder who is not a dealer in securities must treat any gain or loss realized upon a taxable disposition of our common stock as long-term capital gain or loss if the stockholder has held the shares for more than one year, and otherwise as short-term capital gain or loss. However, a U.S. Stockholder must treat any loss upon a sale or exchange of shares of our common stock held for six months or less as a long-term capital loss to the extent of capital gain dividends and any other actual or deemed distributions from us which the stockholder treats as long-term capital gain. All or a portion of any loss that a U.S. Stockholder realizes upon a taxable disposition of our common stock

may be disallowed if the stockholder purchases other shares of our common stock (or certain options to acquire our common stock) within 30 days before or after the disposition.

Tax-exempt organizations, including qualified employee pension and profit sharing trusts and individual retirement accounts (collectively, "Exempt Organizations"), generally are exempt from U.S. federal income taxation. However, they are subject to taxation on their unrelated business taxable income ("UBTI"). While many investments in real estate generate UBTI, the IRS has issued a published ruling that dividend distributions by a REIT to an exempt employee pension trust do not constitute UBTI, provided that the shares of the REIT are not otherwise used in an unrelated trade or business of the exempt employee pension trust. Based on that ruling, and subject to the exceptions discussed below, amounts distributed by us to Exempt Organizations generally should not constitute UBTI. However, if an Exempt Organization finances its acquisition of our common stock with debt, a portion of its income from us will constitute UBTI pursuant to the "debt-financed property" rules. Furthermore, social clubs, voluntary employee benefit associations, supplemental unemployment benefit trusts and qualified group legal services plans that are exempt from taxation under paragraphs (7), (9), (17) and (20), respectively, of Section 501(c) of the Code are subject to different UBTI rules, which generally require them to characterize distributions from us as UBTI. In addition, in certain circumstances, a pension trust that owns more than 10% of our stock is required to treat a percentage of the dividends from us as UBTI.

As used herein, the term "Non-U.S. Stockholder" refers to any beneficial owner of our common stock that is, for U.S. federal income tax purposes, a nonresident alien individual, foreign corporation, foreign estate or foreign trust, but does not include any foreign stockholder whose investment in our stock is "effectively connected" with the conduct of a trade or business in the United States. Such a foreign stockholder, in general, will be subject to U.S. federal income tax with respect to its investment in our stock in the same manner as a U.S. Stockholder (subject to applicable alternative minimum tax and a special alternative minimum tax in the case of nonresident alien individuals). In addition, a foreign corporation receiving income that is treated as effectively connected with a U.S. trade or business also may be subject to an additional 30% "branch profits tax" on its effectively connected earnings and profits (subject to adjustments) unless an applicable tax treaty provides a lower rate or an exemption. Certain certification requirements must be satisfied in order for effectively connected income to be exempt from withholding.

Distributions to Non-U.S. Stockholders that are not attributable to gain from sales or exchanges by us of U.S. real property interests and are not designated by us as capital gain dividends (or deemed distributions of retained capital gains) will be treated as dividends of ordinary income to the extent that they are made out of our current or accumulated earnings and profits. Such distributions ordinarily will be subject to a withholding tax equal to 30% of the gross amount of the distribution unless an applicable tax treaty reduces or eliminates that tax. Distributions in excess of our current and accumulated earnings and profits will not be taxable to a Non-U.S. Stockholder to the extent that such distributions do not exceed the adjusted basis of the stockholder's shares (determined on a share-by-share basis), but rather will reduce the adjusted basis of those shares. To the extent that distributions in excess of current and accumulated earnings and profits exceed the adjusted basis of a Non-U.S. Stockholder's shares, such distributions will give rise to tax liability if the Non-U.S. Stockholder would otherwise be subject to tax on any gain from the sale or disposition of its shares, as described below.

We expect to withhold U.S. tax at the rate of 30% on the gross amount of any dividends, other than dividends treated as attributable to gain from sales or exchanges of U.S. real property interests

and capital gain dividends, paid to a Non-U.S. Stockholder, unless (i) a lower treaty rate applies and the required IRS Form W-8BEN evidencing eligibility for that reduced rate is filed with us or the appropriate withholding agent or (ii) the Non-U.S. Stockholder files an IRS Form W-8ECI or a successor form with us or the appropriate withholding agent properly claiming that the distributions are effectively connected with the Non-U.S. Stockholder's conduct of a U.S. trade or business.

For any year in which we qualify as a REIT, distributions to a Non-U.S. Stockholder that owns more than 5% of our common shares at any time during the one-year period ending on the date of distribution and that are attributable to gain from sales or exchanges by us of U.S. real property interests will be taxed to the Non-U.S. Stockholder under the provisions of the Foreign Investment in Real Property Tax Act of 1980 ("FIRPTA") as if such gain were effectively connected with a U.S. business. Accordingly, a Non-U.S. Stockholder that owns more than 5% of our common shares will be taxed at the normal capital gain rates applicable to a U.S. Stockholder (subject to any applicable alternative minimum tax and a special alternative minimum tax in the case of nonresident alien individuals). Distributions subject to FIRPTA also may be subject to a branch profits tax equal to 30% of its effectively connected earnings and profits (subject to adjustments) if the recipient is a foreign corporate stockholder not entitled to treaty relief or exemption. Under FIRPTA, we are required to withhold 35% (which is higher than the maximum rate on long-term capital gains of non-corporate persons) of any distribution to a Non-U.S. Stockholder that owns more than 5% of our common shares which is or could be designated as a capital gain dividend attributable to U.S. real property interests. Moreover, if we designate previously made distributions as capital gain dividends attributable to U.S. real property interests, subsequent distributions (up to the amount of such prior distributions) will be treated as capital gain dividends subject to FIRPTA withholding. This amount is creditable against the Non-U.S. Stockholder's FIRPTA tax liability.

If a Non-U.S. Stockholder does not own more than 5% of our common shares at any time during the one-year period ending on the date of a distribution, any capital gain distributions, to the extent attributable to sales or exchanges by us of U.S. real property interests, will not be considered to be effectively connected with a U.S. business, and the Non-U.S. Stockholder would not be required to file a U.S. federal income tax return by receiving such a distribution. In that case, the distribution will be treated as a REIT dividend to that Non-U.S. Stockholder and taxed as a REIT dividend that is not a capital gain distribution (and subject to possible withholding), as described above. In addition, the branch profits tax will not apply to the distribution. Any capital gain distribution, to the extent not attributable to sales or exchanges by us of U.S. real property interests, generally will not be subject to U.S. federal income taxation (regardless of the amount of our common shares owned by a Non-U.S. Stockholder). For so long as our common stock continues to be regularly traded on an established securities market, the sale of such stock by any Non-U.S. Stockholder who is not a Five Percent Non-U.S. Stockholder (as defined below) generally will not be subject to U.S. federal income tax (unless the Non-U.S. Stockholder is a nonresident alien individual who was present in the United States for more than 182 days during the taxable year of the sale and certain other conditions apply, in which case such gain (net of certain sources within the U.S., if any) will be subject to a 30% tax on a gross basis). A "Five Percent Non-U.S. Stockholder" is a Non-U.S. Stockholder who, at some time during the five-year period preceding such sale or disposition, beneficially owned (including under certain attribution rules) more than 5% of the total fair market value of our common stock (as outstanding from time to time).

In general, the sale or other taxable disposition of our common stock by a Five Percent Non-U.S. Stockholder also will not be subject to U.S. federal income tax if we are a "domestically controlled REIT." A REIT is a "domestically controlled REIT" if, at all times during the five-year period preceding the disposition in question, less than 50% in value of its shares is held directly or indirectly by Non-U.S. Stockholders. Although we believe that we currently qualify as a domestically controlled REIT, because our common stock is publicly traded, we cannot provide any assurance that we do so qualify or that we will qualify as a domestically controlled REIT at any time in the future. If we do not constitute a domestically controlled REIT, a Five Percent Non-U.S. Stockholder generally will be taxed in the same manner as a U.S. Stockholder with respect to gain on the sale of our common stock (subject to applicable alternative minimum tax and a special alternative minimum tax in the case of nonresident alien individuals).

Information returns may be filed with the IRS and backup withholding tax may be collected in connection with distributions paid or required to be treated as paid during each calendar year and payments of the proceeds of a sale or other disposition of our common stock. Under the backup withholding rules, a stockholder may be subject to backup withholding at the applicable rate (currently 28% and scheduled to increase to 31% in 2013) with respect to distributions paid and proceeds from a disposition of our common stock unless such holder is a corporation, non-U.S. person or comes within certain other exempt categories and, when required, demonstrates this fact or provides a taxpayer identification number, certifies as to no loss of exemption from backup withholding and otherwise complies with the applicable requirements of the backup withholding rules. A stockholder who does not provide us with its correct taxpayer identification number also may be subject to penalties imposed by the IRS.

Backup withholding is not an additional tax. Rather, the U.S. federal income tax liability of persons subject to backup withholding tax will be offset by the amount of tax withheld. If backup withholding tax results in an overpayment of U.S. federal income taxes, a refund or credit may be obtained from the IRS, provided the required information is furnished timely thereto.

As a general matter, backup withholding and information reporting will not apply to a payment of the proceeds of a sale of our common stock by or through a foreign office of a foreign broker. Information reporting (but not backup withholding) will apply, however, to a payment of the proceeds of a sale of our common stock by a foreign office of a broker that is a U.S. person, a foreign partnership that engaged during certain periods in the conduct of a trade or business in the United States or more than 50% of whose capital or profit interests are owned during certain periods by U.S. persons, any foreign person that derives 50% or more of its gross income for certain periods from the conduct of a trade or business in the United States, or a "controlled foreign corporation" for U.S. tax purposes, unless the broker has documentary evidence in its records that the holder is a Non-U.S. Stockholder and certain other conditions are satisfied, or the stockholder otherwise establishes an exemption. Payment to or through a U.S. office of a broker of the proceeds of a sale of our common stock is subject to both backup withholding and information reporting unless the stockholder certifies under penalties of perjury that the stockholder is a Non-U.S. Stockholder or otherwise establishes an exemption. A stockholder may obtain a refund of any amounts withheld under the backup withholding rules in excess of its U.S. federal income tax liability by timely filing the appropriate claim for a refund with the IRS.

We and/or our stockholders may be subject to taxation by various states and localities, including those in which we or a stockholder transact business, own property or reside. State and local tax treatment may differ from the federal income tax treatment described above. Consequently, stockholders should consult their own tax advisers regarding the effect of state and local tax laws, in addition to federal, foreign and other tax laws, in connection with an investment in our common stock.

You should recognize that future legislative, judicial and administrative actions or decisions, which may be retroactive in effect, could adversely affect our federal income tax treatment or the tax consequences of an investment in shares of our common stock. The rules dealing with U.S. federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Treasury Department, resulting in statutory changes as well as promulgation of new, or revisions to existing, regulations and revised interpretations of established concepts.

We cannot predict the likelihood of passage of any new tax legislation or other provisions either directly or indirectly affecting us or our stockholders or the value of an investment in our common stock.

This section discusses the most significant factors that affect our business, operations and financial condition. It does not describe all risks and uncertainties applicable to us, our industry or ownership of our securities. If any of the following risks, or any other risks and uncertainties that we have not yet identified or that we currently deem not material, actually occur, we could be materially adversely affected. In that event, the value of our securities could decline.

We depend on Kindred and Brookdale Senior Living for a significant portion of our revenues and operating income; Any inability or unwillingness by Kindred or Brookdale Senior Living to satisfy its obligations under its agreements with us could have a Material Adverse Effect on us.

The properties we lease to Kindred and Brookdale Senior Living account for a significant portion of our revenues and NOI, and since the Kindred Master Leases and our leases with Brookdale Senior Living are triple-net leases, we also depend on Kindred and Brookdale Senior Living to pay all insurance, taxes, utilities and maintenance and repair expenses in connection with the leased properties. We cannot provide any assurance that Kindred and Brookdale Senior Living will have sufficient assets, income and access to financing to enable them to make rental payments to us or to otherwise satisfy those obligations, and any inability or unwillingness by Kindred or Brookdale Senior Living to do so could have a Material Adverse Effect on us. In addition, any failure by Kindred or Brookdale Senior Living to effectively conduct its operations or to maintain and improve our properties could adversely affect its business reputation and its ability to attract and retain patients and residents in our properties, which could have a Material Adverse Effect on us. Kindred and Brookdale Senior Living have also agreed to indemnify, defend and hold us harmless from and against various claims, litigation and liabilities arising in connection with their respective businesses, and we cannot provide any assurance that either Kindred or Brookdale Senior Living will have sufficient assets, income, access to financing and insurance coverage to enable it to satisfy its indemnification obligations.

The properties managed by Atria and Sunrise account for a significant portion of our revenues and operating income; Although Atria and Sunrise are managers, not tenants, of our properties, adverse developments in their businesses and affairs or financial condition could have a Material Adverse Effect on us.

As of December 31, 2011, Atria and Sunrise, collectively, managed 197 of our seniors housing communities pursuant to long-term management agreements. These properties represent a substantial portion of our portfolio, based on their gross book value, and account for a significant portion of our revenues and NOI. Although we have various rights as the property owner under our management agreements, we rely on Atria's and Sunrise's personnel, good faith, expertise, historical performance, technical resources and information systems, proprietary information and judgment to manage our seniors housing communities efficiently and effectively. We also rely on Atria and Sunrise to set resident fees, to provide accurate property-level financial results for our properties in a timely manner and to otherwise operate our properties in accordance with the terms of our management agreements

and in compliance with all applicable laws and regulations. For example, we depend on Atria's and Sunrise's ability to attract and retain skilled management personnel who are responsible for the day-to-day operations of our seniors housing communities. A shortage of nurses or other trained personnel or general inflationary pressures may force Sunrise or Atria to enhance its pay and benefits package to compete effectively for such personnel, and Atria or Sunrise may not be able to offset such added costs by increasing the rates charged to residents. Any increase in labor costs and other property operating expenses, any failure by Atria or Sunrise to attract and retain qualified personnel, or significant changes in Atria's or Sunrise's senior management could adversely affect the income we receive from our seniors housing communities and have a Material Adverse Effect on us.

Because Atria and Sunrise manage, but do not lease, our properties, we are not directly exposed to their credit risk in the same manner or to the same extent as a triple-net tenant. However, any adverse developments in Atria's or Sunrise's business and affairs or financial condition could impair their ability to manage our properties efficiently and effectively and could have a Material Adverse Effect on us. If Atria or Sunrise experiences any significant financial, legal, accounting or regulatory difficulties due to the weakened economy or otherwise, such difficulties could result in, among other adverse events, acceleration of its indebtedness, impairment of its continued access to capital, the enforcement of default remedies by its counterparties, or the commencement of insolvency proceedings by or against it under the U.S. Bankruptcy Code, any one or a combination of which indirectly could have a Material Adverse Effect on us.

We face potential adverse consequences of bankruptcy or insolvency by our tenants, operators, borrowers, managers and other obligors.

We are exposed to the risk that our tenants, operators, borrowers, managers or other obligors could become bankrupt or insolvent. Although our lease, loan and management agreements provide us with the right to exercise certain remedies in the event of default on the obligations owing to us or upon the occurrence of certain insolvency events, the bankruptcy and insolvency laws afford certain rights to a party that has filed for bankruptcy or reorganization. For example, a debtor-lessee may reject its lease with us in a bankruptcy proceeding. In such a case, our claim against the debtor-lessee for unpaid and future rents would be limited by the statutory cap of the U.S. Bankruptcy Code. This statutory cap could be substantially less than the remaining rent actually owed under the lease, and any claim we have for unpaid rent might not be paid in full. In addition, a debtor-lessee may assert in a bankruptcy proceeding that its lease should be re-characterized as a financing agreement. If such a claim is successful, our rights and remedies as a lender, compared to a landlord, are generally more limited. Similarly, if a debtor-manager seeks bankruptcy protection, the automatic stay provisions of the U.S. Bankruptcy Code would preclude us from enforcing our remedies against the manager unless relief is first obtained from the court having jurisdiction over the bankruptcy case. In the event of an obligor bankruptcy, we may also be required to fund certain expenses and obligations (e.g., real estate taxes, debt costs and maintenance expenses) to preserve the value of our properties, avoid the imposition of liens on our properties or transition our properties to a new tenant, operator or manager.

If we must replace any of our tenants or operators, we might be unable to reposition the properties on as favorable terms, or at all, and we could be subject to delays, limitations and expenses, which could have a Material Adverse Effect on us.

We cannot predict whether our tenants will renew existing leases beyond their current term. If the Kindred Master Leases, our leases with Brookdale Senior Living or any of our other leases are not renewed, we would attempt to reposition those properties with another tenant or operator. In case of non-renewal, we generally have one year prior to expiration of the lease term to arrange for repositioning of the properties and our tenants are required to continue to perform all of their obligations (including the payment of all rental amounts) for the non-renewed assets until such

expiration. However, following expiration of a lease term or if we exercise our right to replace a tenant or operator in default, rental payments on the related properties could decline or cease altogether while we reposition the properties with a suitable replacement tenant or operator. We also might not be successful in identifying suitable replacements or entering into leases with new tenants or operators on a timely basis or on terms as favorable to us as our current leases, if at all, and we may be required to fund certain expenses and obligations (e.g., real estate taxes, debt costs and maintenance expenses) to preserve the value of, and avoid the imposition of liens on, our properties while they are being repositioned. In addition, we may incur certain obligations and liabilities, including obligations to indemnify the replacement tenant or operator, which could have a Material Adverse Effect on us.

Our ability to reposition our properties with a suitable tenant or operator could be significantly delayed or limited by state licensing, receivership, CON or other laws, as well as by the Medicare and Medicaid change-of-ownership rules. We could also incur substantial additional expenses in connection with any licensing, receivership or change-of-ownership proceedings. In addition, our ability to locate suitable replacement tenants could be impaired by the specialized healthcare uses or contractual restrictions on use of the properties, and we may be required to spend substantial amounts to adapt the properties to other uses. Any such delays, limitations and expenses could adversely impact our ability to collect rent, obtain possession of leased properties or otherwise exercise remedies for tenant default and could have a Material Adverse Effect on us.

We have only limited rights to terminate our management agreements with Atria and Sunrise, and we may be unable to replace Atria or Sunrise if our management agreements are terminated or not renewed.

We are parties to long-term management agreements with each of Atria and Sunrise pursuant to which Atria and Sunrise, collectively, provide comprehensive property management and accounting services with respect to 197 of our seniors housing communities.

Each management agreement with Atria has a term of ten years commencing in 2011, subject to successive automatic ten-year renewal periods, and each management agreement with Sunrise has a term of 30 years commencing as early as 2004. Each management agreement with Atria or Sunrise may be terminated by us upon the occurrence of an event of default by Atria or Sunrise, respectively, in the performance of a material covenant or term thereof (including, in certain circumstances, the revocation of any license or certificate necessary for operation), subject in most cases to the defaulting party's right to cure such default, or upon the occurrence of certain insolvency events relating to Atria or Sunrise, respectively. In addition, we may terminate each management agreement with Atria based on the failure to achieve certain NOI targets, and we may terminate each management agreement with Sunrise based on the failure to achieve certain NOI targets or to comply with certain expense control covenants. Under certain circumstances, we may also terminate each management agreement with Atria upon the payment of a fee. Notwithstanding the provisions in our management agreements, legal, contractual and other considerations may limit or delay our exercise of any or all of these termination rights.

In the event that our management agreements with Atria or Sunrise are terminated for any reason or are not renewed upon expiration of their terms, we would attempt to find another manager for the properties covered by those agreements. Although we believe that many qualified national and regional seniors care providers would be interested in managing our seniors housing communities, we cannot provide any assurance that we would be able to locate another suitable manager or, if we are successful in locating such a manager, that it would manage the properties effectively. Moreover, any such replacement manager would require approval by the applicable regulatory authorities and, in most cases, the mortgage lenders for the properties, and we cannot provide any assurance that such approvals would be granted on a timely basis or at all. Any inability or lengthy delay in replacing Atria or Sunrise as manager following termination or non-renewal of our management agreements could have a Material Adverse Effect on us.

Our significant acquisition activity presents certain risks to our business and operations.

In 2010 and 2011, we acquired or signed definitive agreements to acquire more than $12 billion of assets, including our acquisitions of Lillibridge, NHP and substantially all of the real estate assets of ASLG and our pending acquisition of Cogdell. Our significant acquisition activity presents certain risks to our business and operations, including, among other things, that:

We cannot provide any assurance that we will be able to achieve the economic benefit we expect from acquired properties or integrate acquisitions without encountering difficulties or that any such difficulties will not have a Material Adverse Effect on us.

We have now, and may have in the future, exposure to contingent rent escalators, which can hinder our growth and profitability.

We receive a significant portion of our revenues by leasing our assets under long-term triple-net leases in which the rental rate is generally fixed with annual escalations. Certain of our leases contain escalators contingent upon the achievement of specified revenue parameters or based on changes in the Consumer Price Index. If, as a result of weak economic conditions or other factors, the revenues generated by our triple-net leased properties do not meet the specified parameters or the Consumer Price Index does not increase, our growth and profitability will be hindered by these leases.

We are exposed to various operational risks, liabilities and claims with respect to our operating assets, which could adversely affect our ability to generate revenues or increase our costs and could have a Material Adverse Effect on us.

We are exposed to various operational risks, liabilities and claims with respect to our senior living and MOB operating assets, which could increase our costs or adversely affect our ability to generate revenues, thereby reducing our profitability. These operational risks include fluctuations in occupancy levels, the inability to achieve economic resident fees (including anticipated increases in those fees), rent control regulations, increases in costs of food, materials, energy, labor (as a result of unionization or otherwise) and other services, national and regional economic conditions, the imposition of new or increased taxes, capital expenditure requirements, professional and general liability claims, and the availability and cost of professional and general liability insurance. Any or a combination of these factors could result in operating deficiencies in our senior living operations or MOB operations reportable business segments, which could have a Material Adverse Effect on us.

The weakened economy could adversely impact our revenues and operating income, as well as the operating results of our tenants and operators, which could impair their ability to meet their obligations to us.

Continued concerns about the U.S. economy and the systemic impact of high unemployment, volatile energy costs, geopolitical issues, the availability and cost of credit, the U.S. mortgage market and a severely distressed real estate market have contributed to increased market volatility and weakened business and consumer confidence. If this difficult operating environment continues or worsens, it could increase our costs or adversely affect our ability to generate revenues in our senior living and MOB operations, thereby reducing our operating income or causing us to experience operating deficiencies. It could also have an adverse impact on the ability of our tenants and operators to maintain occupancy and rates in our properties, which could harm their financial condition and impair their ability to make their rental payments and satisfy their other obligations to us, which could have a Material Adverse Effect on us.

Legislation to address the federal government's projected operating deficit could have a material adverse effect on our operators' liquidity, financial condition or results of operations.

President Obama and members of the U.S. Congress have recently proposed various spending cuts and tax reform initiatives to reduce the federal government's projected operating deficit. Some of these initiatives could result in changes (including substantial reductions in funding) to Medicare, Medicaid or Medicare Advantage Plans. Future federal legislation relating to deficit reduction that reduces reimbursement payments to healthcare providers could have a material adverse effect on our operators' liquidity, financial condition or results of operations, which could adversely affect their ability to satisfy their obligations to us and could have a Material Adverse Effect on us.

We may be unable to successfully foreclose on the collateral securing our mortgage loan investments, and even if we are successful in our foreclosure efforts, we may be unable to successfully reposition the properties, which may adversely affect our ability to recover our investments.

If a borrower defaults under any of our mortgage loans, to protect our interest, we may foreclose on the loan or acquire title to the property and make substantial improvements or repairs to maximize the property's investment potential. In response to our actions to enforce mortgage obligations, the defaulting borrower may contest enforcement of foreclosure or other remedies, seek bankruptcy protection against our exercise of enforcement or other remedies, or bring claims for lender liability. If the borrower seeks bankruptcy protection, the automatic stay provisions of the U.S. Bankruptcy Code would preclude us from enforcing foreclosure or other remedies against the borrower unless relief is first obtained from the court having jurisdiction over the bankruptcy case. Foreclosure-related costs, high loan-to-value ratios or declines in property value could prevent us from realizing the full amount of our mortgage loans upon foreclosure, and we could be required to record valuation allowance for such losses. Even if we successfully foreclose on the collateral securing our mortgage loan investments, we may inherit properties that we are unable to expeditiously reposition with new tenants or operators, if at all, which would adversely affect our ability to recover our investment.

Our pursuit of investments in, and acquisitions or development of, seniors housing and healthcare assets may be unsuccessful or fail to meet our expectations.

We intend to continue to pursue investments in, and acquisitions or development of, additional seniors housing and healthcare assets domestically and internationally, subject to the contractual restrictions contained in the instruments governing our existing indebtedness. Investments in and acquisitions of these properties entail general risks associated with any real estate investment, including risks that the investment's performance will fail to meet expectations, that the cost estimates for necessary property improvements will prove inaccurate or that the tenant, operator or manager will

underperform. Furthermore, healthcare properties are often highly customized and may require costly tenant-specific improvements.

Our ability to compete successfully for investment and acquisition opportunities is affected by many factors, including our cost of obtaining debt and equity capital at rates comparable to or better than our competitors. When we attempt to finance, acquire or develop properties, we compete with other healthcare REITs, healthcare providers, healthcare lenders, real estate partnerships, banks, insurance companies, private equity firms and other investors, some of whom have greater financial resources and lower costs of capital than we do. Increased competition makes it more challenging for us to identify and successfully capitalize on opportunities that meet our business objectives and could improve the bargaining power of property owners seeking to sell, thereby impeding our investment, acquisition and development activities. See "Business—Competition" included in Item 1 of this Annual Report on Form 10-K.

In addition, new development projects that we pursue may experience construction delays or cost overruns that increase our expenses, fail to obtain required zoning, occupancy and other governmental approvals and permits on a timely basis, or remain incomplete after incurring significant development costs. Investments in and acquisitions of properties outside the United States create additional legal, economic and market risks associated with operating in foreign countries, such as currency exchange fluctuations and foreign tax risks. If we incur additional debt or issue equity securities, or both, to finance future investments, acquisitions or development activity, our leverage could increase or our per share financial results could decline.

Our investments are concentrated in seniors housing and healthcare real estate, making us more vulnerable economically than if our investments were diversified.

We invest primarily in seniors housing and healthcare properties, and our ability to make investments outside the seniors housing or healthcare industries is restricted by the terms of our existing indebtedness. This concentration exposes us to greater economic risk than if our portfolio included real estate assets in other industries or non-real estate assets. For example, the healthcare industry is highly regulated, and changes in government regulation and reimbursement can have material adverse consequences on the healthcare industry, some of which may be unintended. We cannot provide any assurance that future changes in government regulation of healthcare will not adversely affect the healthcare industry, including our seniors housing and healthcare operations, tenants and operators, which could have a more pronounced effect on us than if our investments were further diversified.

The healthcare industry is also highly competitive. The occupancy levels at, and revenues from, our properties depend on the ability of our tenants, operators and managers to successfully compete with other operators and managers, including with respect to the scope and quality of care and services provided, reputation and financial condition, physical appearance of the properties, price and location. We cannot be certain that our tenants, operators and managers will be able to achieve and maintain occupancy and rate levels that will enable them to meet all of their obligations to us, and our operators and managers may encounter increased competition that could limit their ability to attract residents and patients or expand their businesses, which could materially adversely affect their ability to meet their obligations to us and have a Material Adverse Effect on us.

Real estate investments are relatively illiquid, and our ability to quickly sell or exchange our properties in response to changes in economic or other conditions is limited. In the event we desire or need to sell any of our properties, the value of those properties and our ability to sell at a price or on terms acceptable to us could be adversely affected by the current downturn in the real estate industry or any weakness in the seniors housing and healthcare industries. In addition, transfers of healthcare properties may be subject to regulatory approvals that are not required for transfers of other types of

commercial properties. We cannot provide any assurance that we will recognize full value for any property that we sell for liquidity or other reasons, and the inability to respond quickly to changes in the performance of our investments could adversely affect our business, results of operations and financial condition.

Our tenants, operators and managers may be adversely affected by increasing healthcare regulation and enforcement.

Over the last several years, the regulatory environment of the long-term healthcare industry has intensified both in the amount and type of regulations and in the efforts to enforce those regulations. This is particularly true for large for-profit, multi-facility providers like Kindred, Brookdale Senior Living, Atria and Sunrise. The extensive federal, state and local laws and regulations affecting the healthcare industry include those relating to, among other things, licensure, conduct of operations, ownership of facilities, addition of facilities and equipment, allowable costs, services, prices for services, qualified beneficiaries, quality of care, patient rights, fraudulent or abusive behavior, and financial and other arrangements that may be entered into by healthcare providers. Changes in enforcement policies by federal and state governments have resulted in a significant increase in the number of inspections, citations of regulatory deficiencies and other regulatory sanctions, including terminations from the Medicare and Medicaid programs, bars on Medicare and Medicaid payments for new admissions, civil monetary penalties and even criminal penalties. See "Governmental Regulation—Healthcare Regulation" included in Item 1 of this Annual Report on Form 10-K.

If our tenants, operators and managers fail to comply with the extensive laws, regulations and other requirements applicable to their businesses and the operation of our properties, they could become ineligible to receive reimbursement from governmental and private third-party payor programs, face bans on admissions of new patients or residents, suffer civil or criminal penalties or be required to make significant changes to their operations. Our tenants, operators and managers also could be forced to expend considerable resources responding to an investigation or other enforcement action under applicable laws or regulations. In such event, the results of operations and financial condition of our tenants, operators and managers and the results of operations of our properties operated or managed by those entities could be adversely affected, which, in turn, could have a Material Adverse Effect on us. We are unable to predict future federal, state and local regulations and legislation, including the Medicare and Medicaid statutes and regulations, or the intensity of enforcement efforts with respect to such regulations and legislation, and any changes in the regulatory framework could have a material adverse effect on our tenants, operators and managers, which, in turn, could have a Material Adverse Effect on us.

Changes in the reimbursement rates or methods of payment from third-party payors, including the Medicare and Medicaid programs, could have a material adverse effect on certain of our tenants and operators.

Certain of our tenants and operators rely on reimbursement from third-party payors, including the Medicare and Medicaid programs, for substantially all of their revenues. Federal and state legislators and regulators have adopted or proposed various cost-containment measures that would limit payments to healthcare providers, and budget crises and financial shortfalls have caused states to implement or consider Medicaid rate freezes or cuts. See "Governmental Regulation—Healthcare Regulation" included in Item 1 of this Annual Report on Form 10-K. Similarly, private third-party payors have continued their efforts to control healthcare costs. We cannot provide any assurance that adequate reimbursement levels will be available for services to be provided by our tenants and operators that currently depend on Medicare, Medicaid or private payor reimbursement. Significant limits by governmental and private third-party payors on the scope of services reimbursed or on reimbursement rates and fees could have a material adverse effect on the liquidity, financial condition and results of operations of certain of our tenants and operators, which could affect adversely their ability to make rental payments under, and otherwise comply with the terms of, their leases with us.

Revenues from our senior living operations are dependent on private pay sources; Events which adversely affect the ability of seniors and their families to afford daily resident fees at our seniors housing communities could cause our occupancy rates, resident fee revenues and results of operations to decline.

By and large, assisted and independent living services currently are not reimbursable under government reimbursement programs, such as Medicare and Medicaid. Hence, substantially all of the resident fee revenues generated by our senior living operations are derived from private pay sources consisting of income or assets of residents or their family members. In general, due to the expense associated with building new properties and the staffing and other costs of providing services at these properties, only seniors with income or assets meeting or exceeding the comparable median in the regions where our properties are located typically can afford to pay the daily resident and care fees. The continued weak economy and depressed housing market, as well as other events such as changes in demographics, could adversely affect the ability of seniors and their families to afford these fees. If the managers of our seniors housing communities are unable to attract and retain seniors with sufficient income, assets or other resources required to pay the fees associated with assisted and independent living services, our occupancy rates, resident fee revenues and results of operations could decline, which, in turn, could have a Material Adverse Effect on us.

Our investments in joint ventures could be adversely affected by our lack of sole decision-making authority regarding major decisions, our reliance on our joint venture partners' financial condition, any disputes that may arise between us and our joint venture partners, and our exposure to potential losses from the actions of our joint venture partners.

As of December 31, 2011, we had controlling interests in eleven MOBs and eighteen seniors housing communities owned through joint ventures with third parties, and we had noncontrolling interests of between 5% and 25% in 58 MOBs, 20 seniors housing communities and fourteen skilled nursing facilities owned through joint ventures with third parties. These joint ventures involve risks not present with respect to our wholly owned properties, including the following:

Our ownership of twelve seniors housing communities in the Canadian provinces of Ontario and British Columbia subjects us to fluctuations in U.S. and Canadian exchange rates, which may, from time to time, impact our financial condition and results of operations. If we increase our international presence through investments in, or acquisitions or development of, seniors housing or healthcare assets outside the United States, we may transact business in currencies other than U.S. or Canadian dollars. Although we may pursue hedging alternatives, including borrowing in local currencies, to protect against foreign currency fluctuations, we cannot provide any assurance that such fluctuations will not have a Material Adverse Effect on us.

Our ownership of certain properties subject to ground lease, air rights or other restrictive agreements exposes us to the loss of such properties upon breach or termination of such agreements, limits our uses of these properties and restricts our ability to sell or otherwise transfer such properties.

We have investments in many of our MOBs and certain other properties through leasehold interests in the land on which the buildings are located, through leases of air rights for the space above the land on which the buildings are located or through similar agreements, and we may acquire or develop additional properties in the future that are subject to similar ground lease, air rights or other restrictive agreements. Under these agreements, we could lose our interests in the property upon termination or an earlier breach by us. In addition, many of our ground lease, air rights and other restrictive agreements impose significant limitations on our uses of the subject properties, restrict our right to convey our interests in such properties, which may limit our ability to timely sell or exchange the properties and impair their value, or restrict the leasing of such properties, which may negatively impact our ability to find suitable tenants for the properties.

Overbuilding in markets in which our seniors housing communities and MOBs are located could adversely affect our future occupancy rates, operating margins and profitability.

The seniors housing and MOB industries generally have limited barriers to entry, and, as a consequence, the development of new seniors housing communities or MOBs could outpace demand. If development outpaces demand for those asset types in the markets in which our properties are located, those markets may become saturated and we could experience decreased occupancy, reduced operating margins and lower profitability.

Termination of resident lease agreements could adversely affect our revenues and earnings.

Applicable regulations governing assisted living communities generally require a written lease agreement with each resident that gives the resident the right to terminate his or her lease agreement for any reason on reasonable notice. Consistent with these regulations, the resident lease agreements entered into by the managers of our seniors housing communities generally allow residents to terminate their lease agreements on 30 days' notice. Thus, unlike typical apartment lease agreements that have terms of one year or longer, our managers cannot contract with residents to stay for longer periods of time. In addition, the resident turnover rate in our seniors housing communities may be difficult to predict. If a large number of resident lease agreements terminate at or around the same time, and if the affected units remain unoccupied, our revenues and earnings could be adversely affected, which, in turn, could have a Material Adverse Effect on us.

The hospitals on whose campuses our MOBs are located and their affiliated health systems could fail to remain competitive or financially viable, which could adversely impact their ability to attract physicians and physician groups to our MOBs.

Our MOB operations depend on the viability of the hospitals on or near whose campuses our MOBs are located and their affiliated health systems in order to attract physicians and other healthcare-related clients. The viability of these hospitals, in turn, depends on factors such as the quality and mix of healthcare services provided, competition, demographic trends in the surrounding community, market position and growth potential, as well as the ability of the affiliated health systems to provide economies of scale and access to capital. If a hospital on or near whose campus one of our MOBs is located is unable to meet its financial obligations, and if an affiliated health system is unable to support that hospital, the hospital may not be able to compete successfully or could be forced to close or relocate, which could adversely impact its ability to attract physicians and other healthcare-related clients. Because we rely on our proximity to and affiliations with these hospitals to create demand for space in our MOBs, their inability to remain competitive or financially viable, or to attract physicians and physician groups, could materially adversely affect our MOB operations and have a Material Adverse Effect on us.

Volatility or disruption in the capital markets could prevent our counterparties from satisfying their obligations to us.

Uncertainty in the capital markets and tightening of credit markets, similar to that experienced in recent years, could make accessing new capital more challenging and more expensive for our counterparties. Interest rate fluctuations, financial market volatility or credit market disruptions could limit the ability of our tenants, operators and managers to obtain credit to finance their businesses on acceptable terms, which could adversely affect their ability to satisfy their obligations to us. In addition, any difficulty in accessing capital or other sources of funds experienced by our other counterparties, such as letters of credit issuers, insurance carriers, banking institutions, title companies and escrow agents, could prevent such counterparties from remaining viable entities or satisfying their obligations to us, which could have a Material Adverse Effect on us.

The amount and scope of insurance coverage provided by our policies and policies maintained by our tenants, operators and managers may not adequately insure against losses.

We maintain or require in our existing lease, management and other agreements that our tenants, operators and managers maintain adequate insurance coverage on our properties and their operations. Although we continually review the scope and level of insurance maintained by us and our tenants, operators and managers and believe the coverage provided to be customary for similarly situated companies in our industry, we cannot provide any assurance that we or our tenants, operators and managers will continue to be able to maintain adequate levels of insurance. We also cannot provide any assurance that we will continue to require the same levels of insurance coverage under our lease, management and other agreements, that such insurance will be available at a reasonable cost in the future or that the insurance coverage provided will fully cover all losses on our properties upon the occurrence of a catastrophic event, nor can we make any guaranty as to the future financial viability of the insurers.

Should an uninsured loss or a loss in excess of insured limits occur, we could incur substantial liability or lose all or a portion of the capital we have invested in a property, as well as the anticipated future revenues from the property. In such an event, we might nevertheless remain obligated for any mortgage debt or other financial obligations related to the property. We cannot provide any assurance that material uninsured losses, or losses in excess of insurance proceeds, will not occur in the future.

As part of our MOB development business, we provide engineering, construction and architectural services, and any design, construction or systems failures related to the properties we develop may result in substantial injury or damage to clients or third parties. Injury or damage claims may arise in the ordinary course and may be asserted with respect to ongoing or completed projects. Although we maintain liability insurance, if any claim results in a loss, we cannot provide any assurance that our insurance coverage would be adequate to cover the loss in full. If we sustain losses in excess of our insurance coverage, we may be required to make a payment for the difference and could lose our investment in, or experience reduced profits and cash flows from, the affected MOB, which could have a Material Adverse Effect on us.

Significant legal actions could subject us or our tenants, operators and managers to increased operating costs and substantial uninsured liabilities, which could materially adversely affect our or their liquidity, financial condition and results of operations.

From time to time, we may be subject to claims brought against us in lawsuits and other legal proceedings arising out of our alleged actions or the alleged actions of our tenants, operators and managers for which such tenants, operators and managers may have agreed to indemnify, defend and hold us harmless. An unfavorable resolution of any such pending or future litigation could materially adversely affect our or their liquidity, financial condition and results of operations and have a Material Adverse Effect on us.

In some of these cases, we and our tenants, operators and managers may be subject to professional liability claims brought by plaintiffs' attorneys seeking significant punitive damages and attorneys' fees. Due to the historically high frequency and severity of professional liability claims against healthcare and seniors housing providers, the availability of professional liability insurance has been restricted and the premiums on such insurance coverage remain very high. As a result, our insurance coverage and the insurance coverage of our tenants, operators and managers might not cover all claims against us or them and might not be available to us or them at a reasonable cost. If we or our tenants, operators and managers are unable to maintain adequate insurance coverage or are required to pay punitive damages, we or they may be exposed to substantial liabilities.

In an effort to reduce and manage their costs and for various other reasons, many companies in the healthcare industry, including some of our tenants, operators and managers, are pursuing different organizational and corporate structures coupled with self-insurance trusts or programs (commonly referred to as "captives") that may provide them with less insurance coverage. Those companies that insure any part of their general and professional liability risks through their own captive limited purpose entities generally estimate the future cost of general and professional liability through actuarial studies that rely primarily on historical data. However, due to the rise in the number and severity of professional claims against healthcare providers, these actuarial studies may underestimate the future cost of claims, and reserves for future claims may not be adequate to cover the actual cost of those claims. As a result, the tenants, operators and managers of our properties who self-insure could incur large funded and unfunded professional liability expense, which could materially adversely affect their liquidity, financial condition and results of operations and, in turn, their ability to satisfy their obligations to us or, in the case of our senior living operations, our results of operations and, in either case, have a Material Adverse Effect on us. Likewise, if we decide to implement a captive, any large funded and unfunded professional liability expenses that we incur could have a Material Adverse Effect on us.

We may not be able to maintain or expand our relationships with our existing and future hospital and health system clients.

The success of our MOB business depends, to a large extent, on our past, current and future relationships with hospital and health system clients. We invest a significant amount of time to develop

these relationships, and our relationships have helped us to secure acquisition and development opportunities, as well as other advisory, property management and hospital project management projects, with both new and existing clients. If our relationships with hospital or health system clients deteriorate, or if a conflict of interest or non-compete arrangement prevents us from expanding these relationships, our ability to secure new acquisition and development opportunities or other advisory, property management and hospital project management projects could be adversely impacted and our professional reputation within the industry could be damaged.

Our MOB development projects, including development projects undertaken on a fee-for-service basis or through our joint ventures, may not yield anticipated returns.

A key component of our MOB long-term growth strategy is exploring development opportunities and, when appropriate, making investments in those projects. In deciding whether to make an investment in a particular MOB development, we make certain assumptions regarding the expected future performance of that property. These assumptions are subject to risks normally associated with these projects, including, among others, that:

Moreover, in MOB development projects undertaken on a fee-for-service basis, we generally construct properties for clients in exchange for a fixed fee, which creates risks such as the inability to pass on increased labor and construction material costs to our clients, development and construction delays that could give our counterparties the right to receive penalties from us, and bankruptcy or default by our contractors. We attempt to mitigate these risks by establishing certain limits on our obligations, shifting some of the risk to the general contractor or seeking other legal protections, but we cannot provide any assurance that our mitigation efforts will be effective.

If any of the risks described above occur, our MOB development projects, including development projects undertaken on a fee-for-service basis or through our joint ventures, may not yield anticipated returns, which could materially adversely affect our MOB operations and have a Material Adverse Effect on us.

Economic and other conditions that negatively affect geographic areas to which a greater percentage of our NOI is attributed could adversely affect our financial results.

For the year ended December 31, 2011, approximately 42.1% of our NOI was derived from properties located in California (12.5%), Illinois (7.1%), Texas (6.1%), Massachusetts (5.8%), New York (5.7%), and Florida (4.9%). As a result, we are subject to increased exposure to adverse conditions affecting these regions, including downturns in the local economies or changes in local real estate conditions, increased competition or decreased demand, and changes in state-specific legislation, which could adversely affect our business and results of operations.

Our operators who engage in business with the federal government may be sued under a federal whistleblower statute designed to combat fraud and abuse in the healthcare industry. See "Governmental Regulation—Healthcare Regulation" included in Item 1 of this Annual Report on Form 10-K. These lawsuits can involve significant monetary damages and award bounties to private plaintiffs who successfully bring these suits. If any of these lawsuits were to be brought against our operators, such suits combined with increased operating costs and substantial uninsured liabilities could have a material adverse effect on the operators' liquidity, financial condition and results of operation and on their ability to make rental payments to us, which, in turn, could have a Material Adverse Effect on us.

If any of our properties are found to be contaminated, or if we become involved in any environmental disputes, we could incur substantial liabilities and costs.

Under federal and state environmental laws and regulations, a current or former owner of real property may be liable for costs related to the investigation, removal and remediation of hazardous or toxic substances or petroleum that are released from or are present at or under, or that are disposed of in connection with such property. Owners of real property may also face other environmental liabilities, including government fines and penalties imposed by regulatory authorities and damages for injuries to persons, property or natural resources. Environmental laws and regulations often impose liability without regard to whether the owner was aware of, or was responsible for, the presence, release or disposal of hazardous or toxic substances or petroleum. In certain circumstances, environmental liability may result from the activities of a current or former operator of the property. Although we are generally indemnified by the current operators of our properties for contamination caused by them, these indemnities may not adequately cover all environmental costs. See "Governmental Regulation—Environmental Regulation" included in Item 1 of this Annual Report on Form 10-K.

Our success depends, in part, on our ability to retain key personnel, and the loss of any one of them could adversely impact our business.

The success of our business depends, in part, on the leadership and performance of our executive management team and key employees, and our ability to retain and motivate these individuals could significantly impact our future performance. Competition for these individuals is intense, and we cannot provide any assurance that we will retain our key officers and employees or that we will be able to attract and retain other highly qualified individuals in the future. Losing any one or more of these persons could have a Material Adverse Effect on us.

Failure to maintain effective internal control over financial reporting could harm our business, results of operations and financial condition.

Pursuant to the Sarbanes-Oxley Act of 2002, we are required to provide a report by management on internal control over financial reporting, including management's assessment of the effectiveness of

such control. Changes to our business will necessitate ongoing changes to our internal control systems and processes. Internal control over financial reporting may not prevent or detect misstatements because of its inherent limitations, including the possibility of human error, the circumvention or overriding of controls, or fraud. Therefore, even effective internal controls can provide only reasonable assurance with respect to the preparation and fair presentation of financial statements. If we fail to maintain the adequacy of our internal controls, including any failure to implement required new or improved controls, or if we experience difficulties in their implementation, our business, results of operations and financial condition could be materially adversely harmed and we could fail to meet our reporting obligations.

If the liabilities we have assumed in connection with acquisitions are greater than expected, or if there are unknown liabilities, our business could be materially and adversely affected.

We may have certain liabilities in connection with our acquisitions, including, in some cases, contingent liabilities. As we integrate these acquisitions, we may learn additional information about the sellers, the properties, their operations and/or their liabilities that adversely affects us, such as:

As a result, we cannot provide any assurance that our past acquisitions will be successful or will not, in fact, harm our business. Among other things, if the liabilities we have assumed are greater than expected, or if there are obligations relating to the acquired properties or businesses of which we were not aware at the time we completed the acquisition, our business and results of operations could be materially adversely affected.

As of December 31, 2011, we had approximately $6.4 billion of outstanding indebtedness (including capital lease obligations). The instruments governing our existing indebtedness permit us to incur substantial additional debt, including secured debt, and we may elect to meet our capital and liquidity needs through additional borrowings. A high level of indebtedness would require us to dedicate a substantial portion of our cash flow from operations to the payment of debt service, thereby reducing the funds available to implement our business strategy and make distributions to stockholders. A high level of indebtedness could also have the following consequences:

In addition, from time to time, we mortgage our properties to secure payment of indebtedness. If we are unable to meet our mortgage payments, then the encumbered properties could be foreclosed upon or transferred to the mortgagee with a consequent loss of income and asset value.

We are exposed to increases in interest rates, which could reduce our profitability and adversely impact our ability to refinance existing debt, sell assets or engage in acquisition and investment activity, and our decision to hedge against interest rate risk might not be effective.

We receive a significant portion of our revenues by leasing our assets under long-term triple-net leases in which the rental rate is generally fixed with annual rent escalations, subject to certain limitations. Certain of our debt obligations are floating rate obligations with interest rate and related payments that vary with the movement of LIBOR, Bankers' Acceptance or other indexes. The generally fixed rate nature of our revenues and the variable rate nature of certain of our obligations create interest rate risk. Although our operating assets provide a partial hedge against interest rate fluctuations, if interest rates rise, our interest costs for our existing floating rate debt and any new debt we incur would also increase. This increased cost could reduce our profitability, make our lease and other revenues insufficient to meet our obligations, or increase the cost of financing our acquisition and investment activity. Further, rising interest rates could limit our ability to refinance existing debt upon maturity or cause us to pay higher rates upon refinancing. An increase in interest rates may also decrease the amount third parties are willing to pay for our assets, thereby limiting our ability to reposition our portfolio promptly in response to changes in economic or other conditions.

We may seek to manage our exposure to interest rate volatility with hedging arrangements that involve risk, including the risk that counterparties may fail to honor their obligations under these arrangements, that these arrangements may not be effective in reducing our exposure to interest rate changes, that the amount of income we may earn from hedging transactions may be limited by federal tax provisions governing REITs, and that these arrangements may result in higher interest rates than would otherwise be the case. Moreover, no amount of hedging activity can completely insulate us from the risks associated with changes in interest rates. Failure to hedge effectively against interest rate risk, if we choose to engage in such activities, could adversely affect our results of operations and financial condition.

Limitations on our ability to access capital could have an adverse effect on our ability to meet our debt payments, make distributions to our stockholders or make future investments necessary to implement our business strategy.

We cannot provide any assurance that we will be able to raise the necessary capital to meet our debt service obligations, make distributions to our stockholders or make future investments necessary to implement our business strategy, and the failure to do so could have a Material Adverse Effect on us. In recent years, the global capital and credit markets experienced a period of extraordinary turmoil and upheaval, characterized by the bankruptcy, failure or sale of various financial institutions and an unprecedented level of intervention from the U.S. federal government. The disruption in the credit markets, the repricing of credit risk and the deterioration of the financial and real estate markets created difficult conditions for REITs and other companies to access capital or other sources of funds. Although access to capital and other sources of funding have improved, we cannot provide any assurance that conditions will not deteriorate or that our access to capital and other sources of funding will not become constrained, which could adversely affect our results of operation and financial condition. In addition, the federal government's failure to increase the amount of debt that it is statutorily permitted to incur as needed to meet its future financial commitments or a downgrade in the debt rating on U.S. government securities could lead to a weakened U.S. dollar, rising interest rates and constrained access to capital, which could materially adversely affect the U.S. and global economies, increase our costs of borrowing and have a Material Adverse Effect on us.

To address constraints on our access to capital, we could, among other things, (i) obtain commitments from the banks in our lending group or from new banks to fund increased amounts under the terms of our unsecured revolving credit facility or our unsecured term loan facilities, (ii) access the public capital markets, (iii) obtain secured loans from government-sponsored entities, pension funds or similar sources, (iv) decrease or eliminate our distributions to our stockholders or pay taxable stock dividends, or (v) delay or cease our acquisition and investment activity. As with other public companies, our access to debt and equity capital depends, in part, on the trading prices of our senior notes and common stock, which, in turn, depend upon market conditions that change from time to time, such as the market's perception of our financial condition, our growth potential and our current and future earnings and cash distributions. Our failure to meet the market's expectation with regard to future earnings and cash distributions or a significant downgrade in the ratings assigned to our long-term debt could impact our ability to access capital or increase our borrowing costs. If we cannot access capital at an acceptable cost or at all, we may be required to liquidate one or more investments in properties at times that may not permit us to realize the maximum return on those investments, which could also result in adverse tax consequences to us. Restrictions on our uses of, and our right to transfer, properties under certain healthcare regulations, ground leases, mortgages and other agreements to which our properties may be subject could adversely impact our ability to timely liquidate those investments and impair their value.

If the financial institutions that are parties to our unsecured revolving credit facility become capital constrained, tighten their lending standards or become insolvent or if they experience excessive volumes of borrowing requests from other borrowers within a short period of time, they may be unable or unwilling to honor their funding commitments to us, which would adversely affect our ability to draw on our unsecured revolving credit facility and, over time, could negatively impact our ability to consummate acquisitions, repay indebtedness as it matures, fund capital expenditures or make distributions to our stockholders. Adverse conditions in the credit markets could also adversely affect the availability and terms of future borrowings, renewals or refinancings.

Covenants in the instruments governing our existing indebtedness limit our operational flexibility, and a covenant breach could materially adversely affect our operations.

The terms of the instruments governing our existing indebtedness require us to comply with a number of customary financial and other covenants, such as maintaining debt service coverage, leverage ratios and minimum net worth requirements. Our continued ability to incur additional debt and to conduct business in general is subject to our compliance with these covenants, which limit our operational flexibility. Breaches of these covenants could result in defaults under the applicable debt instruments and could trigger defaults under any other indebtedness that is cross-defaulted against such instruments, even if we satisfy our payment obligations. Financial and other covenants that limit our operational flexibility, as well as defaults resulting from our breach of any of these covenants, could have a Material Adverse Effect on us.

Loss of our status as a REIT would have significant adverse consequences for us and the value of our common stock.

If we lose our status as a REIT (currently and/or with respect to any tax years for which the statute of limitations has not expired), we will face serious tax consequences that will substantially reduce the funds available to satisfy our obligations, to implement our business strategy and to make distributions to our stockholders for each of the years involved because:

In addition, in such event we would no longer be required to pay dividends to maintain REIT status, which could adversely affect the value of our common stock.

Qualification as a REIT involves the application of highly technical and complex Code provisions for which there are only limited judicial and administrative interpretations. The determination of factual matters and circumstances not entirely within our control, as well as new legislation, regulations, administrative interpretations or court decisions, may adversely affect our investors or our ability to remain qualified as a REIT for tax purposes. Although we believe that we qualify as a REIT, we cannot provide any assurance that we will continue to qualify as a REIT for tax purposes.

The 90% distribution requirement will decrease our liquidity and may limit our ability to engage in otherwise beneficial transactions.

To comply with the 90% distribution requirement applicable to REITs and to avoid the nondeductible excise tax, we must make distributions to our stockholders. See "Certain U.S. Federal Income Tax Considerations—Requirements for Qualification as a REIT—Annual Distribution Requirements" included in Item 1 of this Annual Report on Form 10-K. However, such distributions may limit our ability to rely upon rental payments from our properties or subsequently acquired properties to finance investments, acquisitions or new developments.

Although we do not anticipate any inability to satisfy the REIT distribution requirement, from time to time, we may not have sufficient cash or other liquid assets to do so. For example, timing differences between the actual receipt of income and actual payment of deductible expenses, on the one hand, and the inclusion of that income and deduction of those expenses in arriving at our taxable income, on the other hand, or non-deductible expenses such as principal amortization or repayments or capital expenditures in excess of non-cash deductions may cause us to fail to have sufficient cash or liquid assets to enable us to satisfy the 90% distribution requirement.

In the event that timing differences occur or we decide to retain cash or to distribute such greater amount as may be necessary to avoid income and excise taxation, we may, if possible, borrow funds, issue additional equity securities, pay taxable stock dividends, distribute other property or securities or engage in a transaction intended to enable us to meet the REIT distribution requirements. Any of these actions may require us to raise additional capital to meet our obligations; however, see "—Risks Arising from Our Capital Structure—Limitations on our ability to access capital could have an adverse effect on our ability to meet our debt payments, make distributions to our stockholders or make future investments necessary to implement our business strategy." The terms of the instruments governing our existing indebtedness restrict our ability to engage in some of these transactions.

To preserve our qualification as a REIT, our certificate of incorporation contains ownership limits with respect to our capital stock that may delay, defer or prevent a change of control of our company.

To assist us in preserving our qualification as a REIT, our certificate of incorporation provides that if a person acquires beneficial ownership of more than 9.9% of our outstanding preferred stock or more than 9.0% of our common stock, the shares that are beneficially owned in excess of the applicable limit are considered to be "excess shares" and are automatically deemed transferred to a trust for the benefit of a charitable institution or other qualifying organization selected by our Board of Directors. The trust is entitled to all dividends with respect to the excess shares and the trustee may exercise all voting power over the excess shares. In addition, we have the right to purchase the excess

shares for a price equal to the lesser of (i) the price per share in the transaction that created the excess shares or (ii) the market price on the day we purchase the shares, but if we do not purchase the excess shares, the trustee of the trust is required to transfer the shares at the direction of our Board of Directors. These ownership limits could delay, defer or prevent a transaction or a change of control that might involve a premium price for our common stock or might otherwise be in the best interests of our stockholders.

If we decide to pay taxable stock dividends to meet the REIT distribution requirements, your tax liability may be greater than the amount of cash you receive.

Under Revenue Procedure 2010-12, the IRS has stated that it will treat stock dividends as distributions for purposes of satisfying the REIT distribution requirements for calendar years 2008 through 2012 if each stockholder can elect to receive the distribution in cash, even if the aggregate cash amount paid to all stockholders is limited, provided certain requirements are met. Accordingly, if we decide to pay a stock dividend in accordance with Revenue Procedure 2010-12, your tax liability with respect to such dividend may be significantly greater than the amount of cash you receive.

As of December 31, 2011, we owned 1,378 properties located in 46 states, the District of Columbia and two Canadian provinces, consisting of: 678 seniors housing communities; 396 skilled nursing facilities; 47 hospitals; 249 MOBs; and eight personal care facilities. We also were in the process of developing three properties as of December 31, 2011. We believe that the asset class, tenant, operator and manager, geographic location, revenue source and business model diversity of our portfolio makes us less susceptible to regional economic downturns and adverse changes in regulation or reimbursement rates or methodologies in any single state or with respect to any particular asset type.

At December 31, 2011, our share of mortgage loan obligations outstanding was $2.7 billion and the consolidated aggregate principal amount was $2.8 billion, secured by 228 of our properties.

The following table sets forth select information regarding our portfolio of properties as of December 31, 2011 for each geographic location in which we own property:

The information contained in "Note 16—Litigation" of the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K is incorporated by reference into this Item 3. Except as set forth therein, we are not a party to, nor is any of our property the subject of, any material pending legal proceedings.

ITEM 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Our common stock, par value $0.25 per share, is listed and traded on the New York Stock Exchange (the "NYSE") under the symbol "VTR." The following table sets forth, for the periods indicated, the high and low sales prices of our common stock as reported on the NYSE and the dividends declared per share.

As of February 14, 2012, we had 288,915,189 shares of our common stock outstanding held by approximately 3,540 stockholders of record.

We pay regular quarterly dividends to holders of our common stock to comply with the provisions of the Code governing REITs. On February 15, 2012, our Board of Directors declared the first quarterly installment of our 2012 dividend in the amount of $0.62 per share, payable in cash on March 29, 2012 to stockholders of record on March 9, 2012. We expect to distribute at least 100% of our taxable net income, after the use of any net operating loss carryforwards, to our stockholders for 2012. See "Certain U.S. Federal Income Tax Considerations—Requirements for Qualification as a REIT—Annual Distribution Requirements" included in Part I, Item 1 of this Annual Report on Form 10-K.

In general, our Board of Directors makes decisions regarding the nature, frequency and amount of our dividends on a quarterly basis. Because the Board considers a number of factors when making these decisions, including our current and future liquidity needs and financial condition, our current and projected results of operations and the performance and credit quality of our tenants, operators, managers and borrowers, we cannot provide any assurance that we will maintain the policy of paying regular quarterly dividends to continue to qualify as a REIT. Please see "Cautionary Statements" and the risk factors included in Part I, Item 1A of this Annual Report on Form 10-K for a description of other factors that may affect our distribution policy.

Our stockholders may reinvest all or a portion of any cash distribution on their shares of our common stock by participating in our Distribution Reinvestment and Stock Purchase Plan, subject to the terms of the plan. See "Note 17—Capital Stock" of the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K.

Certain of our directors, executive officers and other employees have adopted and may, from time to time in the future, adopt non-discretionary, written trading plans that comply with Rule 10b5-1 under the Exchange Act, or otherwise monetize their equity-based compensation.

Each of our executive officers has advised us that he or she has not pledged any of our equity securities to secure "margin loans." Our Securities Trading Policy prohibits our directors, executive officers and employees from buying or selling financial instruments that are designed to hedge or offset a decrease in the market value of our securities.

The table below summarizes repurchases of our common stock made during the quarter ended December 31, 2011:

The following performance graph compares the cumulative total return (including dividends) to the holders of our common stock from December 31, 2006 through December 31, 2011, with the cumulative total returns of the NYSE Composite Index, the FTSE NAREIT Composite REIT Index (the "Composite REIT Index"), the FTSE NAREIT Healthcare Equity REIT Index (the "Healthcare REIT Index") and the S&P 500® Index over the same period. The comparison assumes $100 was invested on December 31, 2006 in our common stock and in each of the foregoing indexes and assumes reinvestment of dividends, as applicable. We have included the NYSE Composite Index in the

performance graph because our common stock is listed on the NYSE. We have included the other indexes (other than the S&P 500® Index, of which we are a member) because we believe that they are either most representative of the industry in which we compete, or otherwise provide a fair basis for comparison with us, and are therefore particularly relevant to an assessment of our performance. The figures in the table below are rounded to the nearest dollar.

companies and between periods on a consistent basis without having to account for differences caused by unanticipated items and other events such as transactions and litigation. We use the National Association of Real Estate Investment Trusts ("NAREIT") definition of FFO. NAREIT defines FFO as net income (computed in accordance with GAAP), excluding gains (or losses) from sales of real estate property and impairment write-downs of depreciable real estate, plus real estate depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. Adjustments for unconsolidated partnerships and joint ventures will be calculated to reflect FFO on the same basis. We define normalized FFO as FFO excluding the following income and expense items (which may be recurring in nature): (a) gains and losses on the sales of real property assets; (b) merger-related costs and expenses, including amortization of intangibles and transition and integration expenses, and deal costs and expenses, including expenses and recoveries relating to our lawsuit against HCP, Inc. and the issuance of preferred stock or bridge loan fees; (c) the impact of any expenses related to asset impairment and valuation allowances, the write-off of unamortized deferred financing fees, or additional costs, expenses, discounts, make-whole payments, penalties or premiums incurred as a result of early retirement or payment of our debt; (d) the non-cash effect of income tax benefits or expenses; (e) the impact of future unannounced acquisitions or divestitures (including pursuant to tenant options to purchase) and capital transactions; (f) the financial impact of contingent consideration; (g) charitable donations made to the Ventas Charitable Foundation; and (h) gains and losses for non-operational foreign currency hedge agreements and changes in the fair value of financial instruments.

: FFO and normalized FFO presented herein are not necessarily identical to FFO and normalized FFO presented by other real estate companies due to the fact that not all real estate companies use the same definitions. FFO and normalized FFO should not be considered alternatives to net income (determined in accordance with GAAP) as indicators of our financial performance or as alternatives to cash flow from operating activities (determined in accordance with GAAP) as measures of our liquidity, nor are FFO and normalized FFO necessarily indicative of sufficient cash flow to fund all of our needs. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Funds From Operations" included in Item 7 of this Annual Report on Form 10-K for a reconciliation of these measures to our GAAP earnings.

ITEM 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis provides information that management believes is relevant to an assessment and understanding of the consolidated results of operations and financial condition of Ventas, Inc. (together with its subsidiaries, unless otherwise indicated or except where the context otherwise requires, "we," "us" or "our"). You should read this discussion in conjunction with our Consolidated Financial Statements and the notes thereto included in Item 8 of this Annual Report on Form 10-K. This Management's Discussion and Analysis will help you understand:

We are a real estate investment trust ("REIT") with a geographically diverse portfolio of seniors housing and healthcare properties throughout the United States and Canada. As of December 31, 2011,

we owned 1,378 properties located in 46 states, the District of Columbia and two Canadian provinces, consisting of: 678 seniors housing communities; 396 skilled nursing facilities; 47 hospitals; 249 medical office buildings ("MOBs"); and eight personal care facilities. We also were in the process of developing three properties as of December 31, 2011. We are headquartered in Chicago, Illinois and have been a constituent member of the S&P 500® Index, a leading indicator of the large cap U.S. equities market, since March 2009.

Our primary business focuses on acquiring and owning seniors housing and healthcare properties and leasing those properties to unaffiliated tenants or operating those properties through independent third-party managers. Through our Lillibridge Healthcare Services, Inc. ("Lillibridge") subsidiary and our ownership interest in PMB Real Estate Services LLC ("PMBRES"), which we acquired in July 2011 in connection with our acquisition of Nationwide Health Properties, Inc. (together with its subsidiaries, "NHP"), we also provide MOB management, leasing, marketing, facility development and advisory services to highly rated hospitals and health systems throughout the United States. In addition, from time to time, we make mortgage loan and other investments relating to seniors housing and healthcare companies or properties.

We currently operate through three reportable business segments: triple-net leased properties, senior living operations and MOB operations. See "Note 20—Segment Information" of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

As of December 31, 2011, we had: 100% ownership interests in 1,257 properties; controlling interests in eleven MOBs and eighteen seniors housing communities owned through joint ventures with third parties; and noncontrolling interests ranging between 5% and 25% in 58 MOBs, 20 seniors housing communities and fourteen skilled nursing facilities owned through joint ventures with third parties. Through Lillibridge and PMBRES, we also provided management and leasing services to third parties with respect to 44 MOBs as of December 31, 2011.

As of December 31, 2011, we leased 929 properties (excluding MOBs) to healthcare operating companies under "triple-net" or "absolute-net" leases that obligate the tenants to pay all property-related expenses, including maintenance, utilities, repairs, taxes, insurance and capital expenditures, and we engaged independent third parties, such as Atria Senior Living, Inc. ("Atria") and Sunrise Senior Living, Inc. (together with its subsidiaries, "Sunrise"), to manage 200 seniors housing communities pursuant to long-term management agreements. Kindred Healthcare, Inc. (together with its subsidiaries, "Kindred") and Brookdale Senior Living Inc. ("Brookdale Senior Living") leased 198 and 167 of our properties, respectively, as of December 31, 2011 (excluding six properties included in investments in unconsolidated entities).

Access to external capital is critical to the success of our business strategy as it impacts our ability to meet our existing commitments, including repaying maturing indebtedness, and to make future investments. Our access to and cost of capital depend on various factors, including general market conditions, interest rates, credit ratings on our securities, perception of our potential future earnings and cash distributions and the market price of our common stock. Generally, we attempt to match the long-term duration of our investments in senior housing and healthcare properties with long-term financing through the issuance of shares of our common stock or the incurrence of fixed rate debt. At December 31, 2011, only 22.1% of our consolidated debt was variable rate debt (excluding debt related to real estate assets classified as held for sale).

Our Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K have been prepared in accordance with generally accepted accounting principles ("GAAP") set forth in the Accounting Standards Codification ("ASC"), as published by the Financial Accounting Standards Board ("FASB"). GAAP requires us to make estimates and assumptions regarding future events that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. We base these estimates on our experience and assumptions we believe to be reasonable under the circumstances. However, if our judgment or interpretation of the facts and circumstances relating to various transactions or other matters had been different, we may have applied a different accounting treatment, resulting in a different presentation of our financial statements. We periodically reevaluate our estimates and assumptions, and in the event they prove to be different from actual results, we make adjustments in subsequent periods to reflect more current estimates and assumptions about matters that are inherently uncertain. We believe that the critical accounting policies described below, among others, affect our more significant estimates and judgments used in the preparation of our financial statements. For more information regarding our critical accounting policies, see "Note 2—Accounting Policies" of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

The Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K include our accounts and the accounts of our wholly owned subsidiaries and the joint venture entities over which we exercise control. All intercompany transactions and balances have been eliminated in

consolidation, and net earnings are reduced by the portion of net earnings attributable to noncontrolling interests.

We apply FASB guidance for arrangements with variable interest entities ("VIEs"), which requires us to identify entities for which control is achieved through means other than voting rights and to determine which business enterprise is the primary beneficiary of the VIE. A VIE is broadly defined as an entity with one or more of the following characteristics: (a) the total equity investment at risk is insufficient to finance the entity's activities without additional subordinated financial support; (b) as a group, the holders of the equity investment at risk lack (i) the ability to make decisions about the entity's activities through voting or similar rights, (ii) the obligation to absorb the expected losses of the entity, or (iii) the right to receive the expected residual returns of the entity; or (c) the equity investors have voting rights that are not proportional to their economic interests, and substantially all of the entity's activities either involve, or are conducted on behalf of, an investor that has disproportionately few voting rights. We consolidate investments in VIEs when we are determined to be the primary beneficiary of the VIE. We may change our original assessment of a VIE due to events such as modifications of contractual arrangements that affect the characteristics or adequacy of the entity's equity investments at risk and the disposal of all or a portion of an interest held by the primary beneficiary. We identify the primary beneficiary of a VIE as the enterprise that has both: (i) the power to direct the activities of the VIE that most significantly impact the entity's economic performance; and (ii) the obligation to absorb losses or the right to receive benefits of the VIE that could be significant to the entity. We perform this analysis on an ongoing basis.

We also apply FASB guidance related to investments in joint ventures based on the type of rights held by the limited partner(s) that may preclude consolidation by the sole general partner in certain circumstances in which the general partner would otherwise consolidate the joint venture. We assess limited partners' rights and their impact on the presumption of control of the limited partnership by the sole general partner when an investor becomes the sole general partner, and we reassess if (i) there is a change to the terms or in the exercisability of the rights of the limited partners, (ii) the sole general partner increases or decreases its ownership of limited partnership interests, or (iii) there is an increase or decrease in the number of outstanding limited partnership interests. We also apply this guidance to managing member interests in limited liability companies.

We account for acquisitions using the acquisition method and allocate the cost of the properties acquired among tangible and recognized intangible assets and liabilities based upon their estimated fair values as of the acquisition date. Recognized intangibles primarily include the value of in-place leases, acquired lease contracts, tenant and customer relationships, trade names/trademarks and goodwill. We do not amortize goodwill, which represents the excess of the purchase price paid over the fair value of the net assets of the acquired business and is included in other assets on our Consolidated Balance Sheets.

Our method for allocating the purchase price to acquired investments in real estate requires us to make subjective assessments for determining fair value of the assets acquired and liabilities assumed. This includes determining the value of the buildings, land and improvements, ground leases, tenant improvements, in-place leases, above and/or below market leases, purchase option intangible assets and/or liabilities, and any debt assumed. These estimates require significant judgment and in some cases involve complex calculations. These allocation assessments directly impact our results of operations, as amounts allocated to certain assets and liabilities have different depreciation or amortization lives. In addition, we amortize the value assigned to above and/or below market leases as a component of revenue, unlike in-place leases and other intangibles, which we include in depreciation and amortization in our Consolidated Statements of Income.

We estimate the fair value of buildings on an as-if-vacant basis and depreciate the building value over the estimated remaining life of the building, not to exceed 35 years. We determine the allocated value of other fixed assets, such as site improvements and furniture, fixtures and equipment, based upon the replacement cost and depreciate such value over the assets' estimated remaining useful lives as determined at the applicable acquisition date. We determine the value of land by considering the sales prices of similar properties in recent transactions or based on (a) internal analyses of recently acquired and existing comparable properties within our portfolio or (b) real estate tax assessed values in relation to the total value of the asset.

The fair value of acquired lease intangibles, if any, reflects (i) the estimated value of any above and/or below market leases, determined by discounting the difference between the estimated market rent and the in-place rent, the resulting intangible asset or liability of which we amortize to revenue over the remaining life of the associated lease plus any bargain renewal periods, and (ii) the estimated value of in-place leases related to the cost to obtain tenants, including leasing commissions, and an estimated value of the absorption period to reflect the value of the rent and recovery costs foregone during a reasonable lease-up period as if the acquired space was vacant, which we amortize to amortization expense over the remaining life of the associated lease. If a lease were to be terminated prior to its stated expiration or not renewed, all unamortized amounts of lease intangibles would be recognized in operations at that time.

We estimate the fair value of purchase option intangible assets or liabilities by discounting the difference between the applicable property's acquisition date fair value and an estimate of the future option price. We do not amortize the resulting intangible asset or liability over the term of the lease, but rather adjust the recognized value of the asset or liability upon exercise of the purchase option.

We estimate the fair value of tenant or other customer relationships acquired, if any, by considering the nature and extent of existing business relationships with the tenant or customer, growth prospects for developing new business with the tenant or customer, the tenant's credit quality, expectations of lease renewals with the tenant, and the potential for significant, additional future leasing arrangements with the tenant and amortize that value over the expected life of the associated arrangements or leases, including the remaining terms of the related leases and any expected renewal periods. We estimate the fair value of trade names/trademarks using a royalty rate methodology and amortize that value over the estimated useful life of the trade name/trademark.

In connection with a business combination, we may assume the rights and obligations under certain lease agreements pursuant to which we become the lessee of a given property. We assume the lease classification previously determined by the prior lessee absent a modification in the assumed lease agreement. In connection with our recent acquisitions, all capital leases acquired or assumed contain bargain purchase options that we intend to exercise. Therefore, we recognized an asset based on the acquisition date fair value of the underlying property and a liability based on the acquisition date fair value of the capital lease obligation. We depreciate assets recognized under capital leases that contain bargain purchase options over the asset's useful life. We assess assumed operating leases, including ground leases, to determine whether the lease terms are favorable or unfavorable given current market conditions on the acquisition date. To the extent the lease terms are favorable or unfavorable relative to market conditions on the acquisition date, we recognize an intangible asset or liability, respectively, at fair value, and we amortize the recognized asset or liability (excluding purchase option intangibles) to interest or rental expense in our Consolidated Statements of Income over the applicable lease term. We include all lease-related intangible assets and all lease-related intangible liabilities within acquired lease intangibles and accounts payable and other liabilities, respectively, on our Consolidated Balance Sheets.

We determine fair value of loans receivable acquired in connection with a business combination by discounting the estimated future cash flows using current interest rates at which similar loans with the same maturities and same terms would be made to borrowers with similar credit ratings. The estimated future cash flows reflect our judgment regarding the uncertainty of those cash flows, so we do not establish a valuation allowance at the acquisition date. We recognize the difference between the acquisition date fair value and the total expected cash flows as interest income using an effective interest method over the life of the applicable loan. Subsequent to the acquisition date, we evaluate changes regarding the uncertainty of future cash flows and the need for a valuation allowance.

We estimate the fair value of noncontrolling interests assumed using assumptions that are consistent with those used in valuing all of the underlying assets and liabilities.

We base the initial carrying value of investments in unconsolidated entities on the fair value of the assets at the time we acquired the joint venture interest. We estimate fair values for our equity method investments based on discounted cash flow models that include all estimated cash inflows and outflows over a specified holding period and, where applicable, any estimated debt premiums or discounts. The capitalization rates, discount rates and credit spreads we use in these models are based upon assumptions that we believe to be within a reasonable range of current market rates for the respective investments.

We generally amortize any difference between our cost basis and the basis reflected at the joint venture level over the lives of the related assets and liabilities and include it in our share of income or loss from unconsolidated entities. In other instances, net income or loss is allocated between the partners in the joint venture based on the hypothetical liquidation at book value method.

We calculate the fair value of long-term debt by discounting the remaining contractual cash flows on each instrument at the current market rate for those borrowings, which we approximate based on the rate we would expect to incur to replace the instrument on the date of acquisition, and recognize any fair value adjustments related to long-term debt as effective yield adjustments over the remaining term of the instrument.

We record a liability for contingent consideration (included in accounts payable and other liabilities on our Consolidated Balance Sheets) at fair value as of the acquisition date and reassess the fair value at the end of each reporting period, with any changes being recognized in earnings. Increases or decreases in the fair value of contingent consideration can result from changes in discount periods, discount rates and probabilities that contingencies will be met.

We periodically evaluate our long-lived assets, primarily consisting of our investments in real estate, for impairment indicators. If indicators of impairment are present, we evaluate the carrying value of the related real estate investments in relation to the future undiscounted cash flows of the underlying operations. In performing this evaluation, we consider market conditions as well as our intent with respect to holding or disposing of the asset. We adjust the net book value of leased properties and other long-lived assets to fair value if the sum of the expected future undiscounted cash flows, including sales proceeds, is less than book value. We recognize an impairment loss at the time we make any such determination.

If impairment indicators arise with respect to intangible assets with finite useful lives, we evaluate impairment by comparing the carrying amount of the asset to the estimated future undiscounted net cash flows to be generated by the asset. If estimated future undiscounted net cash flows are less than the carrying amount of the asset, then we estimate the fair value of the asset. We determine the impairment loss by comparing the estimated fair value of the intangible asset to its carrying value and recognize any shortfall from fair value as a loss in the current period.

We evaluate our equity method investments for impairment whenever events or changes in circumstances indicate that the carrying value of our investment in an unconsolidated joint venture may exceed the fair value. If it is determined that a decline in the fair value of our investment in an unconsolidated joint venture is other-than-temporary, and if such reduced fair value is below its carrying value, an impairment is recorded. The determination of the fair value of investments in unconsolidated joint ventures involves significant judgment. Our estimates consider all available evidence, including, as appropriate, the present value of the expected future cash flows discounted at market rates, general economic conditions and trends and other relevant factors.

Goodwill is tested for impairment at least annually, but more frequently if indicators arise. We first assess qualitative factors to determine the likelihood that the fair value of a reporting unit is less than its carrying amount. Qualitative factors we assess include current macroeconomic conditions, state of the equity and capital markets and our overall financial and operating performance. If we determine it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then we proceed with the two-step approach to evaluating impairment. In the first step of this approach, we estimate the fair value of a reporting unit and compare it to the reporting unit's carrying value. Should the carrying value exceed fair value, we proceed with the second step. The second step of this approach requires the fair value of a reporting unit to be assigned to all the assets and liabilities of the reporting unit as if it had been acquired in a business combination at the date of the impairment test. The excess fair value of the reporting unit over the amounts assigned to the assets and liabilities is the implied value of goodwill and is used to determine the amount of impairment. We recognize an impairment loss to the extent the carrying value of goodwill exceeds the implied value in the current period.

Estimates of fair value used in this evaluation of goodwill, investments in real estate and intangibles are based upon discounted future cash flow projections, which are, in turn, based upon a number of estimates and assumptions, such as revenue and expense growth rates and discount rates. Our ability to accurately predict future operating results and cash flows and estimate and allocate fair values impacts the timing and recognition of impairments. While we believe our assumptions are reasonable, changes in these assumptions may have a material impact on our financial results.

We record loans receivable, other than those acquired in connection with a business combination, on our Consolidated Balance Sheets (either in secured loans receivable, net or, with respect to unsecured loans receivable, other assets) at the unpaid principal balance, net of any deferred origination fees, purchase discounts or premiums and valuation allowances. We amortize net deferred origination fees, which are comprised of loan fees collected from the borrower net of certain direct costs, and purchase discounts or premiums over the contractual life of the loan using the effective interest method and recognize any unamortized balances in income immediately if the loan is repaid before its contractual maturity.

We regularly evaluate the collectibility of loans receivable based on several factors, including without limitation (i) corporate and facility-level financial and operational reports, (ii) compliance with any financial covenants set forth in the applicable loan agreement, (iii) the financial strength of the borrower and any guarantor, (iv) the payment history of the borrower, and (v) current economic conditions. If our evaluation of these factors indicates it is probable that we will be unable to collect all amounts due according to the terms of the applicable loan agreement, we provide a reserve against the portion of the receivable that we estimate may not be collected.

We follow FASB guidance that defines fair value and provides direction for measuring fair value and making the necessary related disclosures. The guidance emphasizes that fair value is a market-

based measurement, not an entity-specific measurement, and should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, the guidance establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within levels one and two of the hierarchy) and the reporting entity's own assumptions about market participant assumptions (unobservable inputs classified within level three of the hierarchy).

Level one inputs utilize unadjusted quoted prices for identical assets or liabilities in active markets that the reporting entity has the ability to access. Level two inputs are inputs other than quoted prices included in level one that are directly or indirectly observable for the asset or liability. Level two inputs may include quoted prices for similar assets and liabilities in active markets, as well as other inputs for the asset or liability, such as interest rates, foreign exchange rates and yield curves, that are observable at commonly quoted intervals. Level three inputs are unobservable inputs for the asset or liability, which are typically based on the reporting entity's own assumptions, as there is little, if any, related market activity. If the determination of the fair value measurement is based on inputs from different levels of the hierarchy, the level within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. If an entity determines there has been a significant decrease in the volume and level of activity for an asset or liability relative to the normal market activity for such asset or liability (or similar assets or liabilities), then transactions or quoted prices may not accurately reflect fair value. In addition, if there is evidence that the transaction for the asset or liability is not orderly, the entity shall place little, if any, weight on that transaction price as an indicator of fair value. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

Certain of our triple-net leases, including the majority of our leases with Brookdale Senior Living and the majority of leases we acquired in connection with the NHP acquisition, and most of our MOB leases provide for periodic and determinable increases in base rent. We recognize base rental revenues under these leases on a straight-line basis over the applicable lease term when collectibility is reasonably assured. Recognizing rental income on a straight-line basis results in recognized revenues during the first half of a lease term exceeding the cash amounts contractually due from our tenants, creating a straight-line rent receivable that is included in other assets on our Consolidated Balance Sheets.

Our master lease agreements with Kindred (the "Kindred Master Leases") and certain of our other leases provide for periodic increases in base rent only if certain revenue parameters or other substantive contingencies are met. We recognize the increased rental revenue under these leases as the related parameters or contingencies are met, rather than on a straight-line basis over the applicable lease term.

We recognize resident fees and services, other than move-in fees, monthly as services are provided. We recognize move-in fees on a straight-line basis over the average resident stay. Our lease agreements with residents generally have a term of twelve to eighteen months and are cancelable by the resident upon 30 days' notice.

We recognize interest income from loans, including discounts and premiums, using the effective interest method when collectibility is reasonably assured. We apply the effective interest method on a loan-by-loan basis and recognize discounts and premiums as yield adjustments over the related loan term. We recognize interest income on an impaired loan to the extent our estimate of the fair value of the collateral is sufficient to support the balance of the loan, other receivables and all related accrued interest. When the balance of the loan, other receivables and all related accrued interest is equal to our estimate of the fair value of the collateral, we recognize interest income on a cash basis. We provide a reserve against an impaired loan to the extent our total investment in the loan exceeds our estimate of the fair value of the loan collateral.

We recognize income from rent, lease termination fees, development services, management advisory services and all other income when all of the following criteria are met in accordance with Securities and Exchange Commission ("SEC") Staff Accounting Bulletin 104: (i) the applicable agreement has been fully executed and delivered; (ii) services have been rendered; (iii) the amount is fixed or determinable; and (iv) collectibility is reasonably assured.

We assess the collectibility of our rent receivables, including straight-line rent receivables, in accordance with the applicable accounting standards and our reserve policy, and we defer recognition of revenue if collectibility is not reasonably assured. We base our assessment of the collectibility of rent receivables (excluding straight-line receivables) on several factors, including, among other things, payment history, the financial strength of the tenant and any guarantors, the value of the underlying collateral, if any, and current economic conditions. If our evaluation of these factors indicates it is probable that we will be unable to recover the full value of the receivable, we provide a reserve against the portion of the receivable that we estimate may not be recovered. We base our assessment of the collectibility of straight-line receivables on several factors, including, among other things, the financial strength of the tenant and any guarantors, the historical operations and operating trends of the property, the historical payment pattern of the tenant, and the type of property. If our evaluation of these factors indicates it is probable that we will be unable to receive the rent payments due in the future, we defer recognition of the straight-line rental income and, in certain circumstances, provide a reserve against the previously recognized straight-line rent receivable asset for a portion, up to its full value, that we estimate may not be recovered. If we change our assumptions or estimates regarding the collectibility of future rent payments required by a lease, we may adjust our reserve to increase or reduce the rental revenue recognized and/or to increase or reduce the reserve against the existing straight-line rent receivable.

We have elected to be treated as a REIT under the applicable provisions of the Internal Revenue Code of 1986, as amended (the "Code"), for every year beginning with the year ended December 31, 1999 and made no provision for federal income tax purposes prior to our acquisition of the assets of Sunrise Senior Living Real Estate Investment Trust ("Sunrise REIT") in April 2007. As a result of the Sunrise REIT and subsequent acquisitions, we now record income tax expense or benefit with respect to certain of our entities that are taxed as "taxable REIT subsidiaries" under provisions similar to those applicable to regular corporations and not under the REIT provisions.

We account for deferred income taxes using the asset and liability method and recognize deferred tax assets and liabilities for the expected future tax consequences of events that have been included in our financial statements or tax returns. Under this method, we determine deferred tax assets and liabilities based on the differences between the financial reporting and tax bases of assets and liabilities

using enacted tax rates in effect for the year in which the differences are expected to reverse. Any increase or decrease in the deferred tax liability that results from a change in circumstances, and that causes a change in our judgment about expected future tax consequences of events, is included in the tax provision when such changes occur. Deferred income taxes also reflect the impact of operating loss and tax credit carryforwards. A valuation allowance is provided if we believe it is more likely than not that all or some portion of the deferred tax asset will not be realized. Any increase or decrease in the valuation allowance that results from a change in circumstances, and that causes a change in our judgment about the realizability of the related deferred tax asset, is included in the tax provision when such changes occur.

In December 2011, the FASB issued Accounting Standards Update ("ASU") 2011-10, Derecognition of in Substance Real Estate—a Scope Clarification ("ASU 2011-10"), which clarifies certain guidance for situations in which a reporting entity ceases to have a controlling financial interest in a subsidiary that is, in substance, real estate as a result of default on the subsidiary's nonrecourse debt. In such situations, ASU 2011-10 requires a company to apply the provisions of ASC Topic 360, Property, Plant, and Equipment, in determining whether it should derecognize the real estate assets. The provisions of ASU 2011-10 will be effective for us beginning with fiscal year 2013, and are not expected to have a significant impact on our Consolidated Financial Statements.

In September 2011, the FASB issued ASU 2011-08, Testing Goodwill for Impairment ("ASU 2011-08"), which permits companies to first assess qualitative factors to determine the likelihood that the fair value of a reporting unit is less than its carrying amount before performing the current two-step analysis. If a company determines it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the company must proceed with the two-step approach to evaluating impairment. We adopted the provisions of ASU 2011-08 in 2011, and the adoption did not impact our Consolidated Financial Statements. Also, on January 1, 2011, we adopted ASU 2010-28, When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts ("ASU 2010-28"). ASU 2010-28 states that if a reporting unit has a carrying amount that is equal to or less than zero and there are qualitative factors that indicate it is more likely than not that a goodwill impairment exists, Step 2 of the goodwill impairment test must be performed. The adoption of ASU 2010-28 also did not impact our Consolidated Financial Statements.

In June 2011, the FASB issued ASU 2011-05, Presentation of Comprehensive Income ("ASU 2011-05"), which amends current guidance found in ASC Topic 220, Comprehensive Income. ASU 2011-05 requires entities to present comprehensive income in either: (i) one continuous financial statement or (ii) two separate but consecutive statements that display net income and the components of other comprehensive income. Totals and individual components of both net income and other comprehensive income must be included in either presentation. In December 2011, the FASB issued ASU 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05 ("ASU 2011-12"). The provisions of ASU 2011-12 indefinitely defer portions of ASU 2011-05 related to the presentation of reclassification of items out of accumulated other comprehensive income. The provisions of both ASU 2011-05 and ASU 2011-12 will be effective for us beginning with the first quarter of 2012.

On January 1, 2011, we adopted ASU 2010-29, Disclosure of Supplementary Pro Forma Information for Business Combinations ("ASU 2010-29"), affecting public entities that enter into business combinations that are material on an individual or aggregate basis. ASU 2010-29 specifies that if a public entity presents comparative financial statements, it should disclose revenues and earnings of the combined entity as though the business combination(s) that occurred during the year had occurred at the beginning of the prior annual reporting period when preparing the pro forma financial information

for both the current and prior reporting periods. The guidance, which is effective for business combinations consummated in reporting periods beginning after December 15, 2010, also requires that pro forma disclosures be accompanied by a narrative description regarding the nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination(s) included in reported pro forma revenues and earnings. We have presented supplementary pro forma information related to our acquisition of substantially all of the real estate assets and working capital of ASLG in May 2011 and our acquisition of NHP in July 2011 in "Note 4—Acquisitions of Real Estate Property" included in Item 8 of this Annual Report on Form 10-K.

In January 2010, the FASB issued ASU 2010-06, Improving Disclosures about Fair Value Measurements ("ASU 2010-06"), which expands required disclosures related to an entity's fair value measurements. Certain provisions of ASU 2010-06 were effective for interim and annual reporting periods beginning after December 15, 2009, and we adopted those provisions as of January 1, 2010. The remaining provisions, which were effective for interim and annual reporting periods beginning after December 15, 2010, require additional disclosures related to purchases, sales, issuances and settlements in an entity's reconciliation of recurring level three investments. We adopted those provisions of ASU 2010-06 as of January 1, 2011. The adoption of ASU 2010-06 did not impact our Consolidated Financial Statements.

As of December 31, 2011, we operated through three reportable business segments: triple-net leased properties, senior living operations and MOB operations. Our triple-net leased properties segment consists of acquiring and owning seniors housing and healthcare properties in the United States and leasing those properties to healthcare operating companies under "triple-net" or "absolute-net" leases that require the tenants to pay all property-related expenses. Our senior living operations segment primarily consists of investments in seniors housing communities located in the United States and Canada for which we engage independent third parties, such as Atria and Sunrise, to manage the operations. Our MOB operations segment primarily consists of acquiring, owning, developing, leasing and managing MOBs. Information provided for "all other" includes revenues such as income from loans and investments and other miscellaneous income and various corporate-level expenses not directly attributable to our three reportable business segments. Assets included in all other consist primarily of corporate assets, including cash, restricted cash, deferred financing costs, loans receivable and miscellaneous accounts receivable.

The table below shows our results of operations for each year and the effect on our income of changes in those results from year to year.

NOI for our triple-net leased properties reportable business segment consists of rental income earned from our triple-net assets and other services revenue. We incur no direct operating expenses for this segment.

Triple-net leased properties segment NOI increased primarily due to $179.2 million of rental income from the properties we acquired in connection with the NHP acquisition, $6.0 million of additional rent resulting from the annual escalators in the rent paid under the Kindred Master Leases effective May 1, 2011, other services revenue directly attributable to the NHP acquisition ($2.2 million) and various rent increases at our other existing triple-net leased properties.

In our triple-net leased properties segment, revenues consist of fixed rental amounts (subject to annual escalations) received directly from our tenants in accordance with the applicable lease terms and generally do not depend on the operating performance of our properties. Accordingly, occupancy information is relevant to the profitability of our tenants' operations but does not directly impact our revenues or financial results. The following table sets forth average occupancy rates related to the triple-net leased properties we owned at December 31, 2011 for the third quarter of 2011, which is the most recent information available to us from our tenants.

The following table summarizes our senior living operations reportable business segment NOI:

In our senior living operations segment, revenues consist of resident fees and services, which include all amounts earned from residents at our seniors housing communities, such as rental fees related to resident leases, extended health care fees and other ancillary service income. Our senior living operations segment revenues increased primarily due to the properties we acquired in connection with the ASLG acquisition ($403.2 million) and an increase in average daily rates. The following table sets forth average resident occupancy rates related to our senior living operating properties during 2011 and 2010:

Property-level operating expenses related to the segment include labor, food, utility, marketing, management and other costs of operating the properties. Property-level operating expenses increased in 2011 over 2010 primarily due to the properties we acquired in connection with the ASLG acquisition ($281.1 million) and the receipt of a $5 million cash payment from Sunrise in 2010 for expense overages.

The following table summarizes our MOB operations reportable business segment NOI:

The increases in MOB operations segment revenues and property-level operating expenses are attributed primarily to the MOBs we acquired in connection with the NHP acquisition ($68.6 million) and a full of year of activity related to the MOBs we acquired in 2010 in connection with the Lillibridge acquisition. The following table sets forth occupancy rates related to our MOB operations segment at December 31, 2011 and 2010:

Medical office building services revenue and costs, which are a direct result of the Lillibridge businesses that we acquired in July 2010, both increased due primarily due to a full year of activity in 2011 and increased construction activity during the second half of 2011 compared to 2010.

All other NOI consists solely of income from loans and investments. Income from loans and investments increased in 2011 over the prior year primarily due to the loans receivable we acquired in connection with the NHP acquisition, gains from the sale of marketable debt securities and additional investments we made in loans receivable during 2010 and 2011, partially offset by decreased interest income related to loans receivable repayments we received during 2011.

The $62.1 million increase in total interest expense, including interest allocated to discontinued operations of $5.3 million and $4.3 million for the years ended December 31, 2011 and 2010, respectively, is attributed primarily to a $117.6 million increase in interest due to higher loan balances and $7.7 million of interest related to the capital leases we assumed in our 2011 acquisitions, partially offset by a $65.1 million decrease in interest due to lower effective interest rates, including the amortization of any fair value adjustments. Our effective interest rate, excluding activity related to our capital leases, was 4.9% for 2011, compared to 6.4% for 2010. A decrease in the average Canadian dollar exchange rate had an unfavorable impact on interest expense of $0.2 million for 2011, versus 2010.

Depreciation and amortization expense increased primarily due to the NHP and ASLG acquisitions and other properties we acquired in 2011.

General, administrative and professional fees increased in 2011 primarily due to our organizational growth.

The loss on extinguishment of debt in 2011 resulted from our early repayment in February 2011 of $307.2 million principal amount of existing mortgage debt, our redemption in July 2011 of $200.0 million principal amount of our 6¹/2% senior notes due 2016 and our termination in October 2011 of our previous unsecured revolving credit facilities. The loss on extinguishment of debt in 2010 resulted from our redemption in June 2010 of all $142.7 million principal amount outstanding of our 7¹/8% senior notes due 2015, our redemption in October 2010 of all $71.7 million principal amount outstanding of our 6⁵/8% senior notes due 2014 and various mortgage debt repayments in December 2010.

Litigation proceeds, net in 2011 reflects our receipt of $102.8 million in payment of the compensatory damages award from HCP arising out of our 2007 Sunrise REIT acquisition, plus certain costs and interest, and the receipt of an additional $125 million from HCP in final settlement of our outstanding lawsuit against HCP, net of certain fees and expenses, the contingent fee for our outside legal counsel and donations to the Ventas Charitable Foundation. No similar events occurred during 2010.

Merger-related expenses and deal costs in both years consisted of expenses relating to our favorable $101.6 million compensatory damages judgment against HCP and subsequent cross-appeals, transition and integration expenses related to consummated transactions and deal costs required by GAAP to be expensed rather than capitalized into the asset value. The transition and integration expenses and deal costs reflect certain fees and expenses incurred in connection with the Lillibridge, ASLG and NHP acquisitions.

Other consists primarily of the fair value adjustment on interest rate swaps we acquired in connection with the ASLG and NHP acquisitions, partially offset by other expenses.

Loss from unconsolidated entities for 2011 and 2010 relates to the noncontrolling interests in joint ventures we acquired in connection with the NHP and Lillibridge acquisitions. At December 31, 2011, these noncontrolling interests ranged between 5% and 25% and related to 58 MOBs, 20 seniors housing communities and fourteen skilled nursing facilities.

Income tax benefit for 2011 was due primarily to the reversal of certain income tax contingency reserves, including interest, related to our 2007 U.S. federal income tax returns and the deferred tax liabilities established in connection with the ASLG acquisition. Income tax expense for 2010 represents amounts related to our taxable REIT subsidiaries as a result of the Sunrise REIT acquisition.

Discontinued operations for 2011 includes activity related to nineteen properties, four of which were sold during 2011 with no resulting gain or loss and fifteen of which were classified as held for sale as of December 31, 2011. Discontinued operations for 2010 includes activity related to nine of the nineteen properties mentioned above that we owned during 2010, a $17.3 million gain on the sale of seven assets sold during 2010, lease termination fees of $0.7 million related to these assets and a $7.9 million previously deferred gain recognized in the fourth quarter of 2010 upon repayment of a note to the buyer.

Net loss attributable to noncontrolling interest for 2011 represents our partners' joint venture interests in 29 MOBs and seniors housing communities, 23 of which we acquired in connection with the NHP acquisition. Net income attributable to noncontrolling interest, net of tax for 2010 represents Sunrise's share of net income from its previous ownership interests in 60 of our seniors housing communities, which we acquired during 2010, and our partners' joint venture interests in six MOBs.

The table below shows our results of operations for each year and the effect on our income of changes in those results from year to year.

Triple-net leased properties reportable business segment NOI increased primarily due to $6.2 million of additional rent resulting from the annual escalators in the rent paid under the Kindred Master Leases effective May 1, 2010, $0.8 million of rental income from a seniors housing community we acquired in 2010 and various rent increases at our other existing properties.

The following table summarizes our senior living operations reportable business segment NOI:

Our senior living operations segment revenues increased primarily due to a decrease in the average Canadian dollar exchange rate, which had a favorable impact of $8.2 million in 2010, $3.3 million of resident fees and services from three seniors housing communities added to our portfolio in 2010 and late 2009, higher occupancy rates and an increase in average daily rates. The following table sets forth average resident occupancy rates related to our senior living operating properties during 2010 and 2009:

Property-level operating expenses increased primarily as a result of a decrease in the average Canadian dollar exchange rate, which had an unfavorable impact of $5.4 million in 2010, $3.1 million of additional expenses from the three seniors housing communities we acquired in 2010 and late 2009 and increased expenses related to occupancy and revenue growth, partially offset by the receipt of a $5 million cash payment from Sunrise in 2010 for expense overages and a decrease of $4.2 million in management fees.

The following table summarizes our MOB operations reportable business segment NOI:

The increases in MOB operations segment revenues and property-level operating expenses are attributed primarily to the MOBs we acquired during 2010 and 2009, including the Lillibridge portfolio. The following table sets forth occupancy rates related to our MOB operations segment at December 31, 2010 and 2009:

All other NOI consists solely of income from loans and investments. Income from loans and investments increased in 2010 over the prior year primarily due to interest earned on the investments we made during 2010 and 2009.

The $0.2 million increase in total interest expense, including interest allocated to discontinued operations of $4.3 million and $5.9 million for the years ended December 31, 2010 and 2009, respectively, is due primarily to increased deferred financing fee amortization, increased land lease payments and a $0.4 million increase in interest from higher effective interest rates, partially offset by a $2.7 million reduction in interest from lower loan balances. Interest expense includes $9.0 million and $7.4 million of amortized deferred financing fees for 2010 and 2009, respectively. Our effective interest rate was 6.4% for 2010, compared to 6.3% for 2009. A decrease in the average Canadian dollar exchange rate had an unfavorable impact on interest expense of $0.7 million in 2010, compared to 2009.

Depreciation and amortization expense increased primarily as a result of the properties we acquired or developed during 2010 and 2009, including the Lillibridge portfolio.

General, administrative and professional fees increased $11.0 million in 2010 over 2009 due primarily to our organizational growth as a result of the Lillibridge acquisition.

The loss on extinguishment of debt in 2010 relates primarily to our redemption in June 2010 of all $142.7 million principal amount then outstanding of our 7¹/8% senior notes due 2015, our redemption in October 2010 of all $71.7 million principal amount then outstanding of our 6⁵/8% senior notes due 2014 and various mortgage repayments in December 2010. The loss on extinguishment of debt in 2009 primarily relates to the purchase, in open market transactions and/or through cash tender offers, of $361.6 million aggregate principal amount of our outstanding senior notes.

Merger-related expenses and deal costs consisted of expenses relating to our favorable $101.6 million jury verdict against HCP and subsequent cross-appeals arising out of our Sunrise REIT acquisition, integration costs related to consummated transactions and deal costs required by GAAP to be expensed rather than capitalized into the asset value, which include certain fees and expenses we incurred in connection with the Lillibridge and ASLG acquisitions.

Other in 2010 resulted primarily from the net change in our forward contract valuation compared to the revaluation of intercompany loans, partially offset by the Canadian exchange rate differential between the trade date and settlement date on a cash payment.

Loss from unconsolidated entities in 2010 relates to the noncontrolling interests in joint ventures we acquired as part of the Lillibridge acquisition. At December 31, 2010, we had ownership interests ranging between 5% and 20% in 58 MOBs. See "Note 4—Acquisitions of Real Estate Property" of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

Income tax expense/benefit before noncontrolling interest in 2010 and 2009 represents amounts related to our taxable REIT subsidiaries as a result of the Sunrise REIT and Lillibridge acquisitions. The change from an income tax benefit in 2009 to a non-cash income tax expense in 2010 is primarily due to increased NOI at our Sunrise-managed seniors housing communities. See "Note 13—Income Taxes" of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

Discontinued operations for 2010 includes a $17.3 million gain on the sale of seven assets sold during 2010, lease termination fees of $0.7 million related to these assets and a $7.9 million previously deferred gain recognized in the fourth quarter of 2010 upon repayment of a note to the buyer.

Discontinued operations for 2009 includes a $66.8 million net gain on the sale of fourteen assets sold during 2009 and a lease termination fee of $2.3 million related to these assets.

Net income attributable to noncontrolling interest, net of tax primarily represents Sunrise's share of net income from its previous ownership percentage in 60 of our seniors housing communities during 2009 and 58 of our seniors housing communities during most of 2010.

We believe that net income, as defined by GAAP, is the most appropriate earnings measurement. However, we consider certain non-GAAP financial measures to be useful supplemental measures of our operating performance. A non-GAAP financial measure is generally defined as one that purports to measure historical or future financial performance, financial position or cash flows, but excludes or includes amounts that would not be so adjusted in the most comparable GAAP measure. Set forth below are descriptions of the non-GAAP financial measures we consider most relevant to our business and useful to investors, as well as reconciliations of these measures to our most directly comparable GAAP financial measures.

The non-GAAP financial measures we present herein are not necessarily identical to those presented by other real estate companies due to the fact that not all real estate companies use the same definitions. These measures should not be considered as alternatives to net income (determined in accordance with GAAP) as indicators of our financial performance or as alternatives to cash flow from operating activities (determined in accordance with GAAP) as measures of our liquidity, nor are these measures necessarily indicative of sufficient cash flow to fund all of our needs. We believe that in order to facilitate a clear understanding of our consolidated historical operating results, these measures should be examined in conjunction with net income as presented in our Consolidated Financial Statements and data included elsewhere in this Annual Report on Form 10-K.

Historical cost accounting for real estate assets implicitly assumes that the value of real estate assets diminishes predictably over time. Since real estate values, instead, have historically risen or fallen with market conditions, many industry investors have considered presentations of operating results for real estate companies that use historical cost accounting to be insufficient by themselves. To overcome this problem, we consider Funds From Operations ("FFO") and normalized FFO appropriate measures of operating performance of an equity REIT. Moreover, we believe that normalized FFO provides useful information because it allows investors, analysts and our management to compare our operating performance to the operating performance of other real estate companies and between periods on a consistent basis without having to account for differences caused by unanticipated items and other events such as transactions and litigation. We use the National Association of Real Estate Investment Trusts ("NAREIT") definition of FFO. NAREIT defines FFO as net income (computed in accordance with GAAP), excluding gains (or losses) from sales of real estate property and impairment write-downs of depreciable real estate, plus real estate depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. Adjustments for unconsolidated partnerships and joint ventures will be calculated to reflect FFO on the same basis. We define normalized FFO as FFO excluding the following income and expense items (which may be recurring in nature): (a) gains and losses on the sales of real property assets; (b) merger-related costs and expenses, including amortization of intangibles and transition and integration expenses, and deal costs and expenses, including expenses and recoveries relating to our lawsuit against HCP and the issuance of preferred stock or bridge loan fees; (c) the impact of any expenses related to asset impairment and valuation allowances, the write-off of unamortized deferred financing fees, or additional costs, expenses, discounts, make-whole payments,

penalties or premiums incurred as a result of early retirement or payment of our debt; (d) the non-cash effect of income tax benefits or expenses; (e) the impact of future unannounced acquisitions or divestitures (including pursuant to tenant options to purchase) and capital transactions; (f) the financial impact of contingent consideration; (g) charitable donations made to the Ventas Charitable Foundation; and (h) gains and losses for non-operational foreign currency hedge agreements and changes in the fair value of financial instruments.

Our FFO and normalized FFO for the five years ended December 31, 2011 are summarized in the following table. Our FFO for the year ended December 31, 2011 increased over the prior year primarily due to the NHP and ASLG acquisitions, higher NOI from our senior living operations and MOB operations reportable business segments, net litigation proceeds and income tax benefit, partially offset by increased merger-related expenses and deal costs, general, administrative and professional fees and interest expense due to our enterprise growth.

We consider Adjusted EBITDA an important supplemental measure to net income because it provides additional information with which to evaluate the performance of our operations and serves as

another indication of our ability to service debt. We define Adjusted EBITDA as earnings before interest, taxes, depreciation and amortization (including non-cash stock-based compensation expense), excluding loss on extinguishment of debt, net litigation proceeds, merger-related expenses and deal costs, gains or losses on sales of real property assets and changes in the fair value of financial instruments (including amounts in discontinued operations). The following is a reconciliation of Adjusted EBITDA to net income (including amounts in discontinued operations) for the years ended December 31, 2011, 2010 and 2009:

We also consider NOI an important supplemental measure to net income because it allows investors, analysts and our management to measure unlevered property-level operating results and to compare our operating results to the operating results of other real estate companies and between periods on a consistent basis. We define NOI as total revenues, less interest and other income, property-level operating expenses and medical office building services costs (including amounts in discontinued operations). The following is a reconciliation of NOI to total revenues (including amounts in discontinued operations) for the years ended December 31, 2011, 2010 and 2009:

Asset/liability management is a key element of our overall risk management program. The objective of asset/liability management is to support the achievement of our business strategy, while maintaining appropriate risk levels. Our asset/liability management process focuses on a variety of risks, including without limitation market risk (primarily interest rate risk and foreign currency exchange risk) and credit risk. Effective management of these risks is an important determinant of the absolute levels and variability of our FFO and net worth. The following discussion addresses our integrated management of assets and liabilities, including the use of derivative financial instruments.

We are exposed to market risk related to fluctuations in interest rates on borrowings under our unsecured revolving credit facility and $500 million term loan facility, floating rate mortgage debt and certain mortgage loans receivable. These market risks result primarily from changes in LIBOR or prime rates. We continuously monitor our level of floating rate debt with respect to total debt and other factors, including our assessment of the current and future economic environment.

The table below sets forth certain information with respect to our debt, excluding premiums, discounts and capital lease obligations.

The variable rate debt in the table above reflects, in part, the effect of $167.6 million notional amount of interest rate swaps with a maturity of February 1, 2013 that effectively convert fixed rate debt to variable rate debt. The increase in our outstanding variable rate debt from December 31, 2010 is primarily attributable to debt assumed in connection with the ASLG and NHP acquisitions, borrowings under our variable rate term loan facility and borrowings under our unsecured revolving credit facility. Pursuant to the terms of certain leases with one of our tenants, if interest rates increase on certain variable rate debt that we have totaling $80.0 million as of December 31, 2011, our tenant is required to pay us additional rent (on a dollar-for-dollar basis) in an amount equal to the increase in interest expense resulting from the increased interest rates. Therefore, the increase in interest expense related to this debt is equally offset by an increase in additional rent due to us from the tenant. Assuming a 100 basis point increase in the weighted average interest rate related to our variable rate debt (excluding debt related to real estate assets classified as held for sale at December 31, 2011), and

assuming no change in our variable rate debt outstanding as of December 31, 2011, interest expense for 2012 would increase, and our net income would decrease, by approximately $13.5 million, or $0.05 per diluted common share. The fair value of our fixed and variable rate debt is based on current interest rates at which we could obtain similar borrowings.

For fixed rate debt, interest rate fluctuations generally affect the fair value, but do not impact our earnings or cash flows. Therefore, interest rate risk does not have a significant impact on our fixed rate debt obligations until such obligations mature or we elect to prepay and refinance them. If interest rates have risen at the time our fixed rate debt matures or is refinanced, our future earnings and cash flows could be adversely affected by additional borrowing costs. Conversely, lower interest rates at the time of maturity or refinancing may lower our overall borrowing costs.

To highlight the sensitivity of our fixed rate debt to changes in interest rates, the following summary shows the effects of a hypothetical instantaneous change of 100 basis points ("BPS") in interest rates as of December 31, 2011 and 2010:

We earn interest from investments in marketable debt securities on a fixed rate basis. We record these investments as available-for-sale at fair value, with unrealized gains and losses recorded as a component of other comprehensive income. Interest rate fluctuations and market conditions will cause the fair value of these investments to change. As of December 31, 2011 and 2010, the aggregate fair value of our marketable debt securities held at December 31, 2011, which had an aggregate original cost of $37.8 million, was $43.3 million and $43.4 million, respectively. During 2011, we sold marketable debt securities and received proceeds of approximately $23.1 million.

As of December 31, 2011, the fair value of our secured and unsecured loans receivable, based on our estimates of currently prevailing interest rates for comparable loans, was $281.5 million. See "Note 6—Loans Receivable" and "Note 11—Fair Values of Financial Instruments" of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

We are subject to fluctuations in U.S. and Canadian exchange rates that may, from time to time, affect our financial condition and results of operations. Increases or decreases in the value of the Canadian dollar impact the amount of net income we earn from our twelve seniors housing communities in Canada. Based solely on our 2011 results, if the Canadian dollar exchange rate were to increase or decrease by $0.10, our net income from these communities would decrease or increase, as applicable, by $0.1 million per year. If we increase our international presence through investments in, or acquisitions or development of, seniors housing or healthcare assets outside the United States, we may also decide to transact additional business or borrow funds under our unsecured revolving credit facility in currencies other than U.S. or Canadian dollars. Although we may decide to pursue hedging alternatives (including additional borrowings in local currencies) to protect against foreign currency fluctuations, we cannot provide any assurance that any such fluctuations will not have a material adverse effect on our business, financial condition, results of operations and liquidity, on our ability to

service our indebtedness and on our ability to make distributions to our stockholders, as required for us to continue to qualify as a REIT (a "Material Adverse Effect").

We may engage in hedging strategies to manage our exposure to market risks in the future, depending on an analysis of the interest rate and foreign currency exchange rate environments and the costs and risks of such strategies. However, we do not use derivative financial instruments for speculative purposes.

We use concentration ratios to understand and evaluate the potential risks of economic downturns or other adverse events affecting our various asset types, geographic locations, business models, or tenants, operators and managers. We evaluate our concentration risk in terms of investment mix, which measures the portion of our investments that consists of a certain asset type or that is operated or managed by a particular tenant, operator or manager, and operations mix, which measures the portion of our operating results that is attributed to a certain tenant or operator, geographic location or business model. The following tables reflect our concentration risk as of the dates and for the periods presented:

(1): Total revenues include medical office building and other services revenue, revenue from loans and investments and interest and other income. Revenues from properties sold or held for sale as of the reporting date are included in this presentation.
(2): Amounts attributable to senior living operations managed by Atria for the year ended December 31, 2011 relate to the period from May 12, 2011, the date of the ASLG acquisition, through December 31, 2011.
(3): Ratios are based on total revenues for each period presented. Total revenues includes medical office building and other services revenue, revenue from loans and investments and interest and other income. Revenues from properties sold as of the reporting date are excluded from this presentation.

See "Non-GAAP Financial Measures" included elsewhere in this Annual Report on Form 10-K for additional disclosure and reconciliations of Adjusted EBITDA and NOI to our net income or total revenues, as applicable, as computed in accordance with GAAP.

We derive a significant portion of our revenue by leasing our assets under long-term triple-net leases in which the rental rate is generally fixed with annual escalators, subject to certain limitations. Some of our triple-net lease escalators are tied to the Consumer Price Index ("CPI"), with caps, floors or collars. We also earn revenue from individual residents at our seniors housing communities managed by independent third parties, such as Atria and Sunrise, and tenants in our MOBs. For the year ended December 31, 2011, 29.4% of our Adjusted EBITDA (including amounts in discontinued operations)

was derived from our senior living operations and MOB operations, where rental rates may fluctuate upon lease rollovers and renewals due to economic or market conditions.

Our reliance on Kindred and Brookdale Senior Living for a significant portion of our revenues and operating income creates credit risk. Our financial condition and results of operations could be weakened and our ability to service our indebtedness and to make distributions to our stockholders could be limited if either Kindred or Brookdale Senior Living was unable or unwilling to satisfy its obligations to us. In addition, any failure by Kindred or Brookdale Senior Living to effectively conduct its operations or to maintain and improve our properties could adversely affect its business reputation or its ability to attract and retain patients and residents in our properties, which could have a Material Adverse Effect on us. See "Risk Factors—Risks Arising from Our Business—We depend on Kindred and Brookdale Senior Living for a significant portion of our revenues and operating income; Any inability or unwillingness by Kindred or Brookdale Senior Living to satisfy its obligations under its agreements with us could have a Material Adverse Effect on us" included in Part I, Item 1A of this Annual Report on Form 10-K and "Note 3—Concentration of Credit Risk" of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

We regularly monitor the credit risk under our lease and other agreements with our tenants and borrowers by, among other things, (i) reviewing and analyzing information regarding the healthcare industry generally, publicly available information regarding tenants, and required information provided by the tenants and borrowers under our lease and other agreements, and (ii) having periodic discussions and visits with tenants, borrowers and their representatives.

Because Atria and Sunrise manage, but do not lease, our properties, we are not directly exposed to their credit risk in the same manner or to the same extent as our triple-net tenants. However, we rely on their personnel, good faith, expertise, historical performance, technical resources and information systems, proprietary information and judgment to manage our seniors housing communities efficiently and effectively. We also rely on Atria and Sunrise to set resident fees and otherwise operate those properties in compliance with the terms of our management agreements. Although we have various rights as the property owner under our management agreements, Atria's or Sunrise's inability or unwillingness to satisfy its obligations under those agreements, to efficiently and effectively manage our properties and to provide timely and accurate accounting information with respect thereto could have a Material Adverse Effect on us. In addition, significant changes in Atria's or Sunrise's senior management or any adverse developments in their businesses and affairs or financial condition could have a Material Adverse Effect on us. See "Risk Factors—Risks Arising from Our Business—The properties managed by Atria and Sunrise account for a significant portion of our revenues and operating income; Although Atria and Sunrise are managers, not tenants, of our properties, adverse developments in their businesses and affairs or financial condition could have a Material Adverse Effect on us" included in Part I, Item 1A of this Annual Report on Form 10-K.

We are exposed to the risk that, as our triple-net leases expire, our tenants may elect not to renew those leases and, in that event, we may be unable to reposition the applicable properties on a timely basis or on the same or better economic terms, if at all. The following table summarizes our triple-net lease expirations currently scheduled to occur over the next ten years (excluding leases related to assets held for sale as of December 31, 2011):

The non-renewal of some or all of our triple-net leases could have a Material Adverse Effect on us. See "Risk Factors—Risks Arising from Our Business—If we must replace any of our tenants or operators, we might be unable to reposition the properties on as favorable terms, or at all, and we could be subject to delays, limitations and expenses, which could have a Material Adverse Effect on us" included in Part I, Item IA of this Annual Report on Form 10-K.

As of December 31, 2011, we had a total of $45.8 million of unrestricted cash and cash equivalents, operating cash and cash related to our senior living operations and MOB operations reportable business segments that is deposited and held in property-level accounts. Funds maintained in the property-level accounts are used primarily for the payment of property-level expenses, debt service payments and certain capital expenditures. As of December 31, 2011, we also had escrow deposits and restricted cash of $76.6 million and $1.5 billion of unused borrowing capacity available under our unsecured revolving credit facility.

During 2011, our principal sources of liquidity were proceeds from the issuance of debt and equity securities, cash flows from operations, borrowings under our unsecured revolving credit facilities and unsecured term loans, proceeds from our loans receivable and marketable securities portfolios, proceeds related to our litigation with HCP and cash on hand. We funded the ASLG acquisition, including deal costs, through the issuance of 24.96 million shares of our common stock, cash on hand, borrowings under our unsecured revolving credit facilities and assumed mortgage financing. We funded the NHP acquisition, including deal costs, through the issuance of 99.8 million shares of our common stock, cash on hand, borrowings under our unsecured revolving credit facilities and the assumption of debt.

During the next twelve months, our principal liquidity needs are to: (i) fund normal operating expenses; (ii) meet our debt service requirements; (iii) repay maturing mortgage and other debt, including our 9% senior notes due 2012 and 8¹/4% senior notes due 2012; (iv) fund capital expenditures for our senior living operations and our MOB operations reportable segments; (v) fund acquisitions, including our pending Cogdell transaction, investments and commitments, including development activities; and (vi) make distributions to our stockholders and unitholders, as required for us to continue to qualify as a REIT. We believe that these liquidity needs generally will be satisfied by cash flows from operations, cash on hand, debt assumptions and financings, issuances of debt and equity securities, including the $600.0 million aggregate principal amount of 4.25% senior notes due 2022 that we issued in February 2012, proceeds from sales of assets and borrowings under our unsecured revolving credit facility and unsecured term loan facility. However, if any of these sources of capital is unavailable to us or is not available at an acceptable cost or if we engage in significant acquisition or investment activity, we may seek or require additional funding from debt assumptions and financings (including secured financings), dispositions of assets (in whole or in part through joint venture arrangements with third parties) and/or the issuance of secured or unsecured long-term debt or other securities. See "Risk Factors—Risks Arising from Our Capital Structure—Limitations on our ability to access capital could have an adverse effect on our ability to meet our debt payments, make distributions to our stockholders or make future investments necessary to implement our business strategy" included in Part I, Item 1A of this Annual Report on Form 10-K.

We expect to fund the Cogdell transaction through borrowings under our unsecured revolving credit facility and assumed mortgage financing. Completion of the transaction is subject to the approval of Cogdell's stockholders, the sale of Cogdell's design-build and development business and certain other customary closing conditions. We expect to complete the transaction in the second quarter of 2012, although we cannot provide any assurance as to whether or when the closing will occur.

As of December 31, 2011, the aggregate borrowing capacity under our unsecured revolving credit facility was $2.0 billion. Borrowings under our unsecured revolving credit facility bear interest at a fluctuating rate per annum equal to a reference rate (the applicable LIBOR for Eurocurrency rate loans and the higher of (i) the federal funds rate plus 0.50%, (ii) the administrative agent's prime rate and (iii) the applicable LIBOR plus 1.0% for base rate loans) plus a spread based on our senior unsecured long-term debt ratings. At December 31, 2011, the applicable spread was 110 basis points for Eurocurrency rate loans and 10 basis points for base rate loans. We also pay a facility fee ranging from 15 to 45 basis points per annum (based on our senior unsecured long-term debt ratings) on the aggregate revolving commitments under the unsecured revolving credit facility. At December 31, 2011, the facility fee was 17.5 basis points. Our unsecured revolving credit facility matures in October 2015, but may be extended for one year at our option, subject to the satisfaction of certain conditions. Under the terms of the unsecured revolving credit facility, our aggregate borrowing capacity may be increased to up to $2.5 billion at our option, subject to the satisfaction of certain conditions.

The agreement governing our unsecured revolving credit facility subjects us to various financial and other restrictive covenants. See "Note 10—Borrowing Arrangements" of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K. We were in compliance with all of these covenants at December 31, 2011.

As of December 31, 2011, we had $200.0 million of borrowings outstanding under an unsecured term loan that matures in September 2013. The term loan is non-amortizing and bears interest at an all-in fixed rate of 4% per annum. We may prepay the term loan at any time on or after September 27, 2012 without penalty or at any time on or after March 27, 2012 and prior to September 27, 2012 with a make-whole payment.

As of December 31, 2011, we also had $500.0 million of borrowings outstanding under an unsecured term loan facility with a weighted average maturity of 4.5 years. Borrowings under the term loan facility bear interest at the applicable LIBOR plus a spread based on our senior unsecured long-term debt ratings (125 basis points at December 31, 2011). The term loan facility is comprised of a three-year tranche and a five-year tranche and contains an accordion feature that permits us to increase our aggregate borrowing capacity thereunder to up to $900.0 million, subject to the satisfaction of certain conditions. Upon entering into the term loan facility, we terminated the commitments under an $800.0 million term loan previously extended to NHP and assumed by us in connection with the NHP acquisition that was scheduled to mature in June 2012. Borrowings under the NHP term loan bore interest at the applicable LIBOR plus 150 basis points or the "Alternate Base Rate" plus 0.50%, and the NHP term loan had a 10 basis point per annum facility fee.

In November 2011, we repaid in full $230.0 million principal amount outstanding of our 3⁷/8% convertible senior notes due 2011 upon maturity. In accordance with the terms of the indenture governing the convertible notes, we paid the principal amount of the notes and accrued but unpaid interest thereon in cash and issued an aggregate of 943,714 shares of our common stock in settlement of the conversion value in excess of the principal amount.

As of December 31, 2011, the following series of senior notes issued by our subsidiaries, Ventas Realty, Limited Partnership and Ventas Capital Corporation (collectively, the "Ventas Issuers"), were outstanding:

In connection with the NHP acquisition, our subsidiary, Nationwide Health Properties, LLC ("NHP LLC"), assumed $991.6 million aggregate principal amount of outstanding unsecured senior notes of NHP. In July 2011, we repaid in full, at par, $339.0 million principal amount then outstanding of NHP LLC's 6.50% senior notes due 2011 upon maturity. As of December 31, 2011, the following series of senior notes of NHP LLC were outstanding:

In February 2012, we issued and sold $600.0 million aggregate principal amount of 4.25% senior notes due 2022, at a public offering price equal to 99.214% of par for total proceeds of $595.3 million, before the underwriting discount and expenses.

Also in February 2012, we exercised our option to redeem all $200.0 million principal amount outstanding of the Ventas Issuers' 6¹/2% senior notes due 2016 pursuant to the terms of the indenture governing the notes. We will pay a total of $206.5 million, plus accrued and unpaid interest, on the redemption date and expect to recognize a loss on extinguishment of debt in the first quarter of 2012.

In July 2011, we redeemed $200.0 million principal amount outstanding of the Ventas Issuers' 6¹/2% senior notes due 2016, at a redemption price equal to 103.25% of par, plus accrued and unpaid interest to the redemption date, pursuant to the call option contained in the indenture governing the notes. As a result, we paid a total of $206.5 million, plus accrued and unpaid interest, on the redemption date and recognized a loss on extinguishment of debt of $8.7 million during the third quarter of 2011.

In May 2011, we issued and sold $700.0 million aggregate principal amount of 4.750% senior notes due 2021, at a public offering price equal to 99.132% of par, for total proceeds of $693.9 million, before the underwriting discount and expenses.

In November 2010, we issued and sold $400.0 million aggregate principal amount of 3.125% senior notes due 2015, at a public offering price equal to 99.528% of par, for total proceeds of $398.1 million, before the underwriting discount and expenses.

In October 2010, we redeemed all $71.7 million principal amount outstanding of the Ventas Issuers' 6⁵/8% senior notes due 2014, at a redemption price equal to 102.21% of par, plus accrued and unpaid interest to the redemption date, pursuant to the call option contained in the indenture governing the notes. As a result, we paid a total of $73.3 million, plus accrued and unpaid interest, on the redemption date and recognized a loss on extinguishment of debt of $2.5 million during the fourth quarter of 2010.

In September 2010, the subsidiary guarantees on the Ventas Issuers' then outstanding senior notes (other than the 9% senior notes due 2012) were released pursuant to the terms of the indentures governing the notes.

In June 2010, we redeemed all $142.7 million principal amount outstanding of the Ventas Issuers' 7¹/8% senior notes due 2015, at a redemption price equal to 103.56% of par, plus accrued and unpaid interest to the redemption date, pursuant to the call option contained in the indenture governing the notes. As a result, we paid a total of $147.8 million, plus accrued and unpaid interest, on the redemption date and recognized a net loss on extinguishment of debt of $6.4 million during the second quarter of 2010.

In May 2010, we repaid in full, at par, $1.4 million principal amount then outstanding of the Ventas Issuers' 6³/4% senior notes due 2010 upon maturity.

We may, from time to time, seek to retire or purchase additional amounts of our outstanding senior notes for cash and/or in exchange for equity securities in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions, prospects for future access to capital and other factors. The amounts involved may be material.

The indentures governing our outstanding senior notes subject us to various financial and other restrictive covenants. However, at any time we maintain investment grade ratings by both Moody's Investors Service and Standard & Poor's Ratings Services, the indentures governing the Ventas Issuers' senior notes due 2012, 2016 and 2017 provide that certain of these restrictive covenants will either be suspended or fall away. See "Note 10—Borrowing Arrangements" of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K. We were in compliance with all of these covenants at December 31, 2011.

Our share of facility-level mortgage debt outstanding was $2.7 billion and $1.3 billion as of December 31, 2011 and 2010, respectively, and the consolidated aggregate principal amount was $2.8 billion and $1.3 billion as of December 31, 2011 and 2010, respectively.

During 2011, we assumed mortgage debt of $1.6 billion, including $1.2 billion and $442 million, respectively, in connection with the ASLG and NHP acquisitions. See "Note 4—Acquisitions of Real Estate Property" of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

In February 2011, we repaid in full mortgage loans outstanding in the aggregate principal amount of $307.2 million and recognized a loss on extinguishment of debt of $16.5 million in connection with these repayments in the first quarter of 2011.

During 2010, we assumed $79.5 million of mortgage debt in connection with our acquisition of Lillibridge and its related entities. See "Note 4—Acquisitions of Real Estate Property" of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

In June 2010, we repaid $49.8 million of mortgage loans on two of our Sunrise-managed properties in which, at that time, we had 80% ownership interests. In connection with our payment of Sunrise's share ($9.9 million) of those mortgage loans, we acquired Sunrise's 20% noncontrolling interests in the properties.

In order to continue to qualify as a REIT, we must make annual distributions to our stockholders of at least 90% of our REIT taxable income (excluding net capital gain). In 2011, our Board of Directors declared and we paid cash dividends aggregating $2.30 per share, which exceeds 100% of our 2011 estimated taxable income after the use of any net operating loss carryforwards. We also intend to pay dividends greater than 100% of our taxable income, after the use of any net operating loss carryforwards, for 2012. On February 15, 2012, our Board of Directors declared the first quarter 2012 dividend of $0.62 per share, payable in cash on March 29, 2012 to holders of record on March 9, 2012.

We expect that our REIT taxable income will be less than our cash flows due to the allowance of depreciation and other non-cash deductions in computing REIT taxable income. Although we do not anticipate any inability to satisfy the 90% distribution requirement, from time to time, we may not have sufficient cash on hand or other liquid assets to meet this requirement or we may decide to retain cash or distribute such greater amount as may be necessary to avoid income and excise taxation. If we do not have sufficient cash on hand or other liquid assets to enable us to satisfy the 90% distribution requirement, or if we desire to retain cash, we may borrow funds, issue additional equity securities, pay taxable stock dividends, if possible, distribute other property or securities or engage in a transaction intended to enable us to meet the REIT distribution requirements or any combination of the foregoing. See "Certain U.S. Federal Income Tax Considerations—Requirements for Qualification as a REIT—Annual Distribution Requirements" included in Part I, Item 1 of this Annual Report on Form 10-K.

The terms of our triple-net leases generally obligate our tenants to maintain and improve our triple-net leased properties. Accordingly, we do not expect to incur any major capital expenditures in connection with these properties. From time to time, however, we may fund the capital expenditures for our triple-net leased properties through loans to the tenants or advances, some of which may increase the amount of rent payable with respect to the properties. After the terms of the triple-net leases expire, or in the event that our tenants are unable or unwilling to meet their obligations under

those leases, we would expect to fund any capital expenditures for which we may become responsible with cash flows from operations or through additional borrowings.

With respect to our senior living operations and MOB operations reportable business segments, we expect that capital expenditures will be funded by the cash flows from the properties or through additional borrowings. To the extent that unanticipated expenditures or significant borrowings are required, our liquidity may be affected adversely. Our ability to borrow additional funds may be restricted in certain circumstances by the terms of the instruments governing our outstanding indebtedness.

As a result of the NHP acquisition, we assumed certain obligations under agreements to develop seniors housing and MOB properties. The construction of these properties is funded through capital provided by us and, in some circumstances, other joint venture members. As of December 31, 2011, one seniors housing community and two MOBs were in various stages of development pursuant to our agreements. We have funded $45.0 million through December 31, 2011 toward these development projects, and our total commitment to these projects is estimated to be between $90 million and $100 million over the development period.

In November 2011, we filed a shelf registration statement relating to our Distribution Reinvestment and Stock Purchase Plan ("DRIP"), under which existing stockholders may purchase shares of common stock by reinvesting all or a portion of the cash distribution on their shares of our common stock, subject to certain limits.

In July 2011, we filed a shelf registration statement relating to the offer and sale, from time to time, of up to 2,103,086 shares of our common stock that we may issue upon redemption of the Class A limited partnership units in NHP/PMB L.P. See "Note 2—Accounting Policies" of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

In July 2011, following approval by our stockholders, we amended our Amended and Restated Certificate of Incorporation, as previously amended, to increase the number of authorized shares of our capital stock to 610,000,000, comprised of 600,000,000 shares of common stock, par value $0.25 per share, and 10,000,000 shares of preferred stock, par value $1.00 per share.

In May 2011, we filed a shelf registration statement relating to the resale by the selling stockholders of the shares of our common stock issued as partial consideration for the ASLG acquisition. In January 2012, the selling stockholders completed an underwritten public offering of 21,070,658 shares of our common stock pursuant to the resale shelf registration statement. We did not receive any proceeds from the offering.

In February 2011, we completed the sale of 5,563,000 shares of our common stock in an underwritten public offering pursuant to our shelf registration statement for $300.0 million in aggregate proceeds.

In March 2010, we filed a shelf registration statement relating to the resale, from time to time, by the selling stockholders of shares of our common stock issued upon conversion of our 3⁷/8% convertible senior notes due 2011.

We received proceeds of $1.8 million and $11.1 million for the years ended December 31, 2011 and 2010, respectively, from the exercises of outstanding stock options. Future proceeds from the exercises of stock options will be primarily affected by the future trading price of our common stock and the number of options outstanding. Options outstanding (excluding options we assumed in connection with the NHP acquisition) increased to 2.0 million as of December 31, 2011, from 1.7 million as of December 31, 2010. The weighted average exercise price was $42.10 as of December 31, 2011.

We issued approximately 13,500 and 41,600 shares of common stock under the DRIP for net proceeds of $0.6 million and $2.1 million for the years ended December 31, 2011 and 2010, respectively. We currently offer a 1% discount on the purchase price of our stock to shareholders who reinvest their dividends and/or make optional cash purchases of common stock through the plan. Each month or quarter, as applicable, we may lower or eliminate the discount without prior notice, thereby affecting the future proceeds that we receive from this plan.

The following table sets forth our sources and uses of cash flows for the years ended December 31, 2011 and 2010:
