Income Tax Disclosure [Abstract]
Income Taxes	Note 10 – Income Taxes The Company computes its quarterly income tax expense/(benefit) by using a forecasted annual effective tax rate and adjusts for any discrete items arising during the quarter. The Company recorded an income tax expense/(benefit) of $19 million and $(242) million for the three months ended March 31, 2019 and 2020, respectively. During the three months ended March 31, 2019, income tax expense was primarily driven by current tax on foreign earnings partially offset by the benefit of U.S. losses. During the three months ended March 31, 2020, the income tax benefit was primarily driven by the deferred U.S. tax impact of the impairment charges related to the Company’s investments in Didi and Grab, the deferred China tax impact of the impairment charge related to the Company’s investment in Didi, and to a lesser extent, the benefit of U.S. losses and current tax on foreign earnings. The primary differences between the effective tax rate and the federal statutory tax rate are due to the valuation allowance on the Company’s U.S. and Netherlands’ deferred tax assets, foreign tax rate differences, and the benefit from the impairment charges related the Company’s investments in Didi and Grab. During the three months ended March 31, 2020, the amount of gross unrecognized tax benefits increased by $55 million, of which substantially all, if recognized, would not affect the effective tax rate as these unrecognized tax benefits would increase deferred tax assets that would be subject to a full valuation allowance. The Company is subject to taxation in the U.S. and various state and foreign jurisdictions. The Company is also under routine examination by federal, various state, and foreign tax authorities. The Company believes that adequate amounts have been reserved in these jurisdictions. To the extent the Company has tax attribute carryforwards, the tax years in which the attribute was generated may still be adjusted upon examination by federal, state or foreign tax authorities to the extent utilized in a future period. For the Company’s major tax jurisdictions, the tax years 2010 through 2020 remain open; the major tax jurisdictions are the U.S., Brazil, Netherlands, United Kingdom, Australia, and India. Although the timing of the resolution and/or closure of audits is highly uncertain, the Company does not expect any material changes to its unrecognized tax benefits within the next 12 months. Given the number of years remaining subject to examination and the number of matters being examined, the Company is unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits. In the event the Company experiences an ownership change within the meaning of Section 382 of the Internal Revenue Code (“IRC”), the Company’s ability to utilize net operating losses, tax credits and other tax attributes may be limited. The most recent analysis of the Company’s historical ownership changes was completed through March 31, 2020. Based on the analysis, the Company does not anticipate a current limitation on the tax attributes. In response to the Coronavirus pandemic, governments in certain countries have enacted legislation, including the Coronavirus Aid, Relief, and Economic Security Act enacted by the United States on March 27, 2020. The Company currently does not expect a material impact on the provision for income tax as a result of recent legislative developments.
