Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE 12—INCOME TAXES We have elected to be taxed as a REIT under the applicable provisions of the Internal Revenue Code of 1986, as amended, for every year beginning with the year ended December 31, 1999. We have also elected for certain of our subsidiaries to be treated as taxable REIT subsidiaries (“TRS” or “TRS entities”), which are subject to federal, state and foreign income taxes. All entities other than the TRS entities are collectively referred to as the “REIT” within this Note. Certain REIT entities are subject to foreign income tax. Although the TRS entities and certain other foreign entities have paid minimal cash federal, state and foreign income taxes for the three months ended March 31, 2018, their income tax liabilities may increase in future periods as we exhaust net operating loss (“NOL”) carryforwards and as our senior living and other operations grow. Such increases could be significant. Our consolidated provisions for income taxes for the three months ended March 31, 2018 and 2017 were benefits of $3.2 million and $3.1 million, respectively. The income tax benefits for the three months ended March 31, 2018 and 2017, were each due primarily to operating losses at our taxable REIT subsidiaries. Realization of a deferred tax benefit related to NOLs depends, in part, upon generating sufficient taxable income in future periods. The REIT and TRS NOL carryforwards begin to expire in 2024. Each TRS is a tax paying component for purposes of classifying deferred tax assets and liabilities. Net deferred tax liabilities with respect to our TRS entities totaled $244.7 million and $250.1 million as of March 31, 2018 and December 31, 2017, respectively, and related primarily to differences between the financial reporting and tax bases of fixed and intangible assets, net of loss carryforwards. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“2017 Tax Act”) was signed into law making significant changes to the Internal Revenue Code. As of December 31, 2017, we made a reasonable estimate that the new interest expense limitation rules may disallow the deferred interest carried forward under the rules prior to the 2017 Tax Act. Consequently, we recorded a provisional adjustment of $23.3 million for the entire deferred tax asset related to the existing deferred interest carryforward. This amount continues to be a provisional adjustment as of March 31, 2018. We will recognize any changes to provisional amounts as we continue to analyze the existing statute or as additional guidance becomes available. We expect to complete our analysis of the provisional amounts by the end of 2018. Generally, we are subject to audit under the statute of limitations by the Internal Revenue Service for the year ended December 31, 2014 and subsequent years and are subject to audit by state taxing authorities for the year ended December 31, 2013 and subsequent years. We are subject to audit generally under the statutes of limitation by the Canada Revenue Agency and provincial authorities with respect to the Canadian entities for the year ended December 31, 2013 and subsequent years. We are also subject to audit in Canada for periods subsequent to the acquisition, and certain prior periods, with respect to the entities acquired in 2014 from Holiday Retirement. We are subject to audit in the United Kingdom generally for periods ended in and subsequent to 2016.

NOTE 12—INCOME TAXES

We have elected to be taxed as a REIT under the applicable provisions of the Internal Revenue Code of 1986, as amended, for every year beginning with the year ended December 31, 1999.

Although the TRS entities and certain other foreign entities have paid minimal cash federal, state and foreign income taxes for the three months ended March 31, 2018, their income tax liabilities may increase in future periods as we exhaust net operating loss (“NOL”) carryforwards and as our senior living and other operations grow. Such increases could be significant.

Our consolidated provisions for income taxes for the three months ended March 31, 2018 and 2017 were benefits of $3.2 million and $3.1 million, respectively. The income tax benefits for the three months ended March 31, 2018 and 2017, were each due primarily to operating losses at our taxable REIT subsidiaries.

Realization of a deferred tax benefit related to NOLs depends, in part, upon generating sufficient taxable income in future periods. The REIT and TRS NOL carryforwards begin to expire in 2024.
