Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We determine our provision for income taxes for interim periods using an estimate of our annual effective tax rate. We record any changes affecting the estimated annual effective tax rate in the interim period in which the change occurs, including discrete items. For the three months ended September 30, 2020, the effective tax rate was a 10.8% benefit on a pre-tax loss, compared to a 27.4% expense on pre-tax income for the three months ended September 30, 2019. The change in the effective tax rate was primarily due to discrete items. For the nine months ended September 30, 2020, the effective tax rate was a 12.0% benefit on a pre-tax loss, compared to a 24.5% expense on pre-tax income for the nine months ended September 30, 2019. The change in the effective tax rate was primarily driven by nondeductible impairment charges and a valuation allowance principally related to unrealized capital losses recorded in the first quarter of 2020. We are subject to taxation in the United States and foreign jurisdictions. Our income tax filings are regularly examined by federal, state and foreign tax authorities. During the fourth quarter of 2019, the Internal Revenue Service (“IRS”) issued final adjustments related to transfer pricing with our foreign subsidiaries for our 2011 to 2013 tax years. The proposed adjustments would increase our U.S. taxable income by $696 million, which would result in federal tax of approximately $244 million, subject to interest. We do not agree with the position of the IRS. We filed a protest with the IRS for our 2011 to 2013 tax years and Appeals returned the case to Exam for further review. We are also under examination by the IRS for our 2014 to 2016 tax years. Subsequent years remain open to examination by the IRS. We do not anticipate a significant impact to our gross unrecognized tax benefits within the next 12 months related to these years.
