Income Tax Disclosure [Abstract]
Income Taxes	Note 8: Income Taxes We are organized in conformity with, and operate in a manner that will allow us to elect to be taxed as a REIT, for U.S. federal income tax purposes for our tax year ending December 31, 2017. We expect to continue to be organized and operate so as to qualify as a REIT. To qualify as a REIT, we must continually satisfy requirements related to, among other things, the real estate qualification of sources of our income, the real estate composition and values of our assets, the amounts we distribute to our stockholders annually and the diversity of ownership of our stock. To the extent we qualify as a REIT, we generally will not be subject to U.S. federal income tax on taxable income generated by our REIT activities that we distribute to our stockholders. Accordingly, no provision for U.S. federal income taxes has been included in our accompanying condensed consolidated financial statements for the three months ended March 31, 2018 and 2017 related to our REIT activities other than amounts associated with net built-in gains related to our asset sales and the derecognition of deferred tax liabilities discussed below. The Tax Cuts and Jobs Act (the “Act”) was enacted on December 22, 2017. The Act, which amended the Internal Revenue Code of 1986, was the most significant tax legislative development in decades. Major elements of the Act from our perspective include reducing the corporate tax rate; restricting the eligibility for tax deferred like-kind exchange treatment solely to real property; limiting the deductibility of interest expense; and the one-time transition tax on foreign cash and unremitted earnings. At March 31, 2018, we have not completed the internal assessment for the tax effects of enactment of the Act; specifically, the analysis to determine the potential tax liability and deferred tax related to a potential sale of ancillary hotel furniture, fixtures, and equipment that may be sold in a like-kind exchange transaction was not able to be completed. Accordingly, Staff Accounting Bulletin 118, issued by the SEC, states that companies that are unable to calculate a reasonable estimate are able to record the adjustment to the tax provision as the information becomes available, but no later than one year from the enactment date. We intend to continue our analysis and record the effects of the provision through deferred taxes when the information is available and an assessment is made. We are and will continue to be subject to U.S. federal income tax on taxable sales of built-in gain property (representing property with an excess of fair value over tax basis held by us on January 4, 2017) during the five-year period following our election to be taxed as a REIT. In addition, we are subject to non-U.S. income tax on foreign held REIT activities. Further, our taxable REIT subsidiaries are generally subject to U.S. federal, state and local, and foreign income taxes (as applicable). During the three months ended March 31, 2018, we recognized a $5 million deferred tax benefit, which includes built-in losses recognized on assets sold during the period, for which a deferred tax asset was not previously recognized. We recognized an income tax benefit for the three months ended March 31, 2017 of $2,288 million as a result of the derecognition of deferred tax liabilities associated with our intention to be taxed as a REIT.

Note 8: Income Taxes

We are organized in conformity with, and operate in a manner that will allow us to elect to be taxed as a REIT, for U.S. federal income tax purposes for our tax year ending December 31, 2017. We expect to continue to be organized and operate so as to qualify as a REIT.
