Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For interim financial reporting, we estimate the annual tax rate based on projected pre-tax income (loss) for the full year and record a quarterly income tax provision (benefit) in accordance with accounting guidance for income taxes. As the year progresses, we refine the estimate of the year’s pre-tax income (loss) as new information becomes available. The continual estimation process often results in a change to the expected effective tax rate for the year. When this occurs, we adjust the income tax provision (benefit) during the quarter in which the change in estimate occurs so that the year-to-date provision reflects the most current expected annual tax rate. Our effective tax rate was (4.7)% and 15.3% for the three months ended March 31, 2021 and 2020, respectively. The quarterly variance in effective tax rates is primarily due to the beneficial impact in the prior year period from the five-year net operating loss carryback provision included in the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), as well as a change in the geographical mix of income. We are subject to tax in many U.S. and non-U.S. jurisdictions. In many non-U.S. jurisdictions we are taxed on bases such as deemed profits or withholding taxes based on revenue. Consequently, the level of correlation between our pre-tax income and our income tax provision varies from period to period. We are under audit by certain non-U.S. jurisdictions for the years 2008 - 2019. We do not expect the results of these audits to have any material effect on our financial statements. As of March 31, 2021, there were no significant changes to our uncertain tax positions as reported in our audited financial statements for the year ended December 31, 2020.
