Investments In Unconsolidated Entities [Abstract]
INVESTMENTS IN UNCONSOLIDATED ENTITIES	NOTE 6 — INVESTMENTS IN UNCONSOLIDATED ENTITIES We report investments in unconsolidated entities, which we acquired in connection with our Lillibridge and NHP acquisitions, over whose operating and financial policies we have the ability to exercise significant influence under the equity method of accounting. We serve as the managing member of each unconsolidated entity and provide various services in exchange for fees and reimbursements. Our joint venture partners have significant participating rights, and, therefore, we are not required to consolidate these entities. Additionally, these entities are viable entities controlled by equity holders with sufficient capital and, therefore, are not considered variable interest entities. At September 30, 2011 and December 31, 2010, we owned interests (ranging between 5% and 25%) in 92 properties and interests (ranging between 5% and 20%) in 58 properties, respectively, that were accounted for under the equity method. Our net investment in these properties as of September 30, 2011 and December 31, 2010 was $119.3 million and $15.3 million, respectively. For the three months ended September 30, 2011 and 2010, we recorded income from unconsolidated entities of $0.2 million and a loss from unconsolidated entities of $0.4 million, respectively. For the nine months ended September 30, 2011 and 2010, we recorded a loss from unconsolidated entities of $0.1 million and $0.4 million, respectively.
