Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2021
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For interim periods, our income tax expense or benefit is computed based on our estimated annual effective tax rate and any discrete items that impact the interim periods. We recorded a tax expense of $1.7 million for the three months ended March 31, 2021, compared to a tax benefit of $14.4 million for the three months ended March 31, 2020. The estimated annual effective tax rates for the three months ended March 31, 2021 and 2020 were impacted by losses in jurisdictions where the recording of a tax benefit is not available. Furthermore, the tax expense or benefit recorded can vary from period to period depending on the Company’s relative mix of earnings and losses by jurisdiction. The tax benefit for the three months ended March 31, 2020 includes a $16.6 million benefit related to a carryback claim for U.S. federal tax losses based on provisions in the U.S. Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) which was signed into law on March 27, 2020. The CARES Act provided relief to corporate taxpayers by permitting a five-year carryback of 2018-2020 NOLs, increased the 30% limitation on interest expense deductibility to 50% of adjusted taxable income for 2019 and 2020, and accelerated refunds for minimum tax credit carryforwards, among other provisions. The tax effects of changes in tax laws are recognized in the period in which the law is enacted. We have deferred tax assets related to net operating loss and other tax carryforwards in the U.S. and in certain states and foreign jurisdictions. We recognize deferred tax assets to the extent that we believe these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning and recent operating results. As of March 31, 2021, we do not anticipate being able to fully utilize all of the losses prior to their expiration in the following jurisdictions: the U.S., the U.K., Germany, Singapore, China and Saudi Arabia. As a result, we have certain valuation allowances against our deferred tax assets as of March 31, 2021.
