Income Taxes [Abstract]
Income Taxes	12. Income Taxes The difference in the Company's effective tax rates for both the three and nine months ended September 30, 2014 and 2013 was primarily due to the reversal of the valuation allowance that had been recorded against the Company's deferred tax assets. The Company recorded a valuation allowance against deferred tax benefits generated from 2011 through 2013, and in the first two quarters of 2014. The Company evaluates its deferred tax assets each quarter to determine if a valuation allowance is required based on whether it is more likely than not that some portion of the deferred tax asset would not be realized. As a result of the acquisition of Emeritus in the three months ended September 30, 2014, the Company recorded deferred tax liabilities in excess of deferred tax assets that reflect the difference between the fair market value of the acquired assets over the historical tax basis of the acquired assets. The Company determined that it is more likely than not that its federal NOL's and tax credits will be utilized in the future, based on future reversal of these deferred tax liabilities. As a result, the Company recorded an aggregate deferred federal, state and local income tax benefit of $63.7 million from the release of the valuation allowance against certain deferred tax assets in the three months ended September 30, 2014. Additionally, the Company recorded an aggregate deferred federal, state and local tax benefit of $50.5 million as a result of the operating loss for the three months ended September 30, 2014. The Company's valuation allowance as of September 30, 2014 and December 31, 2013 is $16.6 million and $72.4 million, respectively. The Company's current tax expense continues to mainly reflect its cash tax position for states that do not allow for or have suspended the use of net operating losses for the period. The Company recorded interest charges related to its tax contingency reserve for cash tax positions for the nine months ended September 30, 2014 which are included in income tax expense (benefit) for the period. Tax returns for years 2010 through 2013 are subject to future examination by tax authorities. In addition, the net operating losses from prior years are subject to adjustment under examination.
