Acquisitions and Dispositions [Abstract]
Acquisitions and Dispositions	4. Acquisitions and Dispositions Effective February 2, 2012, the Company acquired the underlying real estate associated with nine communities that were previously leased for an aggregate purchase price of $121.3 million. The results of operations of these communities, prior and subsequent to the acquisition, are reported in the Retirement Centers segment. The Company financed the transaction with $77.9 million of first mortgage financing secured by seven of the communities and $15.0 million of seller-financing secured by two of the communities (Note 8). During the six months ended June 30, 2012, the Company purchased three home health agencies and an existing skilled nursing facility as part of its growth strategy for an aggregate purchase price of approximately $6.5 million. The purchase price of the acquisitions has primarily been ascribed to an indefinite useful life intangible asset and recorded on the condensed consolidated balance sheet under other intangible assets, net. Horizon Bay/HCP Transactions On September 1, 2011, the Company acquired 100% of the equity and voting interests in Horizon Bay Realty, L.L.C. ("Horizon Bay"). The results of Horizon Bay's operations have been included in the condensed consolidated financial statements since that date. Horizon Bay is a seniors housing management company primarily focused on managing large portfolios of retirement communities across the United States for institutional real estate investors. In connection with the acquisition, the Company also restructured Horizon Bay's existing relationship with HCP, Inc. ("HCP") relating to 33 communities that Horizon Bay leased from HCP. In particular, the Company (i) formed a joint venture with HCP to own and operate 21 communities (the "HCP RIDEA JV"), and (ii) leased the remaining 12 communities from HCP under long-term, triple net leases. Of these 12 communities, the Company assumed the pre-existing lease for eight communities and entered into a new lease for the remaining four communities. The joint venture with HCP utilizes a RIDEA structure with the Company having acquired a 10% non-controlling interest in the joint venture. The Company also manages the communities under a ten-year management agreement with four five-year renewal options and retains all ancillary services operations. As part of the transactions, the Company entered into an agreement to restructure Horizon Bay's management arrangements with Chartwell Seniors Housing Real Estate Investment Trust ("Chartwell"). Certain elements of the Chartwell management arrangement restructuring are subject to lender and other third party approvals. Until such approvals are received, the Company will operate Chartwell's properties under the existing management contracts. The Company estimated fair values of the assets acquired and liabilities assumed at the acquisition date and is in the process of obtaining third-party valuations of self-insured liabilities; thus the provisional measurements of accrued expenses and other liabilities are subject to change. The Company purchased 100% of Horizon Bay in a transaction that involved the restructuring of certain leases and other elements of Horizon Bay's capital structure. The fair value of identifiable assets acquired and liabilities assumed exceeded the fair value of the consideration transferred. Consequently, the Company reassessed the recognition and measurement of identifiable assets acquired and liabilities assumed and concluded that all acquired assets and assumed liabilities were recognized and that the valuation procedures and resulting measures were appropriate. As a result, the Company initially recognized a net non-cash gain of $2.0 million in 2011 which was subsequently reduced by approximately $0.6 million in the six months ended June 30, 2012 due to adjustments related to pre-acquisition self-insurance reserves and the related tax impact. The loss of $0.6 million is included in the line item "loss on acquisition" in the condensed consolidated statements of operations. The aggregate acquisition-date fair value of the purchase consideration transferred for the acquisition of Horizon Bay included $2.7 million of contingent consideration. The contingent consideration arrangement requires the Company to pay up to a maximum of approximately $3.4 million to Horizon Bay's former members. The Company estimated the fair value of the contingent consideration using a probability-weighted discounted cash flow model. This fair value measurement is based on significant inputs not observable in the market and thus represents a Level 3 measurement as defined in ASC 820. The key assumption in applying the income approach was the assignment of probabilities to the various possible outcomes. As of June 30, 2012, there were no significant changes in the range of outcomes for the contingent consideration recognized as a result of the acquisition of Horizon Bay.
