DESCRIPTION OF BUSINESS

Ventas, Inc. (together with its subsidiaries, unless otherwise indicated or except where the context otherwise requires, "we," "us" or "our") is 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 September 30, 2012, we owned 1,450 properties located in 46 states, the District of Columbia and two Canadian provinces, consisting of: 677 seniors housing communities; 404 skilled nursing and other facilities; 322 medical office buildings ("MOBs"); and 47 hospitals. We were also in the process of developing five properties as of September 30, 2012. 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 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"), 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 loans and other investments relating to seniors housing and healthcare companies or properties.

        As of September 30, 2012, we leased 913 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 215 seniors housing communities pursuant to long-term management agreements.
