Acquisitions [Abstract]
Acquisitions and Dispositions	4. Acquisitions and Dispositions 2016 Community Dispositions The Company designates communities as held for sale when it is probable that the properties will be sold. The Company records these assets on the condensed consolidated balance sheet at the lesser of the carrying value and fair value less estimated selling costs. If the carrying value is greater than the fair value less the estimated selling costs, the Company records an impairment charge. The Company allocates a portion of the goodwill of a reporting unit to the disposal if the disposal constitutes a business. The Company determines the fair value of the communities based primarily on purchase and sale agreements from prospective purchasers (Level 2 input). The Company evaluates the fair value of the assets held for sale each period to determine if it has changed. The long-lived assets are not depreciated while classified as held for sale. As of December 31, 2015, the Company identified 17 communities as held for sale. Impairment charges related to communities identified as held for sale as of December 31, 2015 totaled $15.2 million and were recognized as impairment expense in the fourth quarter of 2015 within the Company's condensed consolidated statements of operations. During the three months ended March 31, 2016, the Company recognized $2.6 million of impairment charges related to these communities previously identified as held for sale, primarily due to changes in the estimated fair value of the assets held for sale. During the three months ended March 31, 2016, the Company sold seven of the communities previously classified as held for sale for an aggregate selling price of $46.7 million. The Company recorded a $2.7 million net gain on the sale of these communities within the Company's condensed consolidated statement of operations. The results of operations of these communities are reported in the Assisted Living and CCRCs – Rental segments through the disposition dates. As of June 30, 2016, the Company identified 50 additional owned communities as held for sale. During the three months ended June 30, 2016, the Company entered into an agreement to sell 44 communities for an aggregate sales price of $252.5 million. In addition, the Company entered into agreements to sell six communities for an aggregate sales price of $42.4 million. The results of operations of the 50 communities are reported in the Assisted Living (46 communities), Retirement Center (one community) and CCRCs – Rental (three communities) segments within the condensed consolidated financial statements. Impairment charges related to communities identified as held for sale during the three months ended June 30, 2016 totaled $2.4 million and were recognized as impairment expense in the second quarter of 2016 within the Company's condensed consolidated statements of operations. As of June 30, 2016, $354.6 million was recorded as assets held for sale and $154.7 million of mortgage debt was included in the current portion of long-term debt within the Company's condensed consolidated balance sheet related to the 60 communities classified as held for sale. This debt will either be repaid with the proceeds from the sales or be assumed by the prospective purchasers. The sale of these communities is expected to occur in the next 12 months, although there can be no assurance that the transactions will close or if they do, when the actual closing will occur. 2015 Community Acquisitions In February 2015, the Company acquired the underlying real estate associated with 15 communities that were previously leased for an aggregate purchase price of $268.6 million. The results of operations of these communities are reported in the Retirement Centers, Assisted Living, and CCRCs – Rental segments within the condensed consolidated financial statements. The fair value of the communities acquired was determined to approximate $187.2 million. The fair values of the property, plant and equipment of the acquired communities were determined utilizing a direct capitalization method considering stabilized facility operating income and market capitalization rates. These fair value measurements were based on current market conditions as of the acquisition date and are considered Level 3 measurements within the fair value hierarchy. The range of capitalization rates utilized was 6.25% to 8.75%, depending upon the property type, geographical location, and the quality of the respective community. The Company recorded the difference between the amount paid and the estimated fair value of the communities acquired ($76.1 million) as a loss on facility lease termination on the condensed consolidated statement of operations for the six months ended June 30, 2015, which includes the reversal of $5.3 million of deferred lease liabilities associated with the termination of the operating lease agreements. The payment for the termination of the lease agreements has been included within net cash provided by operating activities within the condensed consolidated statement of cash flows for the six months ended June 30, 2015.
