Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's effective income tax rate was (27.2)% for the six months ended June 30, 2018, compared to 10.8% for the six months ended June 30, 2017. The effective income tax rate for the six months ended June 30, 2018, would have been 10.0% without the discrete benefit of $670 million, as discussed further below. The effective income tax rate for the six months ended June 30, 2018, reflects a 17% statutory tax rate on the Company's Singapore operations, a 21% corporate income tax rate for its domestic operations and a zero percent tax rate on its Macao gaming operations due to the Company's income tax exemption in Macao, effective through the end of 2018. In December 2017, the U.S. enacted the Tax Cuts and Jobs Act (the "Act"). The Company recorded a discrete benefit of $526 million in the fourth quarter of 2017 related to the reduction of the valuation allowance on certain deferred tax assets previously determined not likely to be utilized and also the revaluation of its U.S. deferred tax liabilities at the reduced corporate income tax rate of 21%. This discrete benefit was the provisional impact of enactment of the Act subject to Staff Accounting Bulletin ("SAB") 118, which provides for a 12-month remeasurement period to complete the accounting required under Accounting Standards Codification ("ASC") 740. The Act made significant changes to U.S. income tax laws, including transitioning from a worldwide tax system to a territorial tax system. This change in the U.S. international tax system included the introduction of several new tax regimes that are effective as of January 1, 2018. One of the new taxes introduced is the Global Intangible Low-Taxed Income ("GILTI"), which effectively taxes the foreign earnings of U.S. multinational companies at 10.5%, half of the current corporate tax rate. During the three months ended March 31, 2018, the Company concluded how the foreign tax credits associated with this income, and allowed against the U.S. tax liability, would be utilized and the potential impact on the foreign tax credit deferred tax asset and related valuation allowance. As a result, the Company recorded a tax benefit of $670 million relating to the reduction of the valuation allowance on certain U.S. foreign tax credit assets generated prior to 2018 that were previously determined not likely to be utilized. While management believes the provisional amounts recorded during the six months ended June 30, 2018 and the year ended December 31, 2017, represent reasonable estimates of the ultimate impact U.S. tax reform will have on the Company's consolidated financial statements, it is possible the Company may continue to materially adjust these amounts for related administrative guidance, notices, implementation regulations, potential legislative amendments and interpretations as the Act continues to evolve. These adjustments could have an impact on the Company's tax assets and liabilities, effective tax rate, net income and earnings per share.
