Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted. Among other provisions, the CARES Act allows for the carryback of certain tax losses and favorably impacts the deductibility of interest expense and depreciation. The CARES Act had a material impact on our financial statements and has been accounted for in the benefit/provision for income taxes for the nine months ended September 30, 2020. Our effective tax rate for continuing operations was 106.1% and 5.9% for the three and nine months ended September 30, 2020, respectively, and 18.2% and (21.2)% for the three and nine months ended September 30, 2019, respectively. The 2020 year-to-date effective tax rate for continuing operations differs from the U.S. federal statutory tax rate of 21% primarily due to the impact of the impairment of nondeductible goodwill which is treated as a permanent difference. The year-to-date effective tax rate was also impacted by the CARES Act, the anticipated withholding taxes which would be due upon repatriation of the unremitted earnings of foreign subsidiaries, and the impact of losses in jurisdictions where it is more likely than not that a tax benefit will not be realized. The effective tax rate for the three months ended September 30, 2020, was primarily impacted by the effect of the impairment of nondeductible goodwill on the estimated annual effective tax rate and a change in the estimated impact of the CARES Act. The 2019 effective tax rate differs from the U.S. federal statutory tax rate of 21% principally due to a discrete tax charge of $6.0 million related to final tax regulations published by the Department of the Treasury and Internal Revenue Service on February 4, 2019. The effective tax rate for the three months ended September 30, 2019, was primarily impacted by changes in the full year forecast book income (loss) within each jurisdiction in which we operate. During the three months ended September 30, 2020, we realized a tax benefit in discontinued operations related to estimated tax in excess of book outside basis in a subsidiary held for sale. The related deferred tax asset is not included in current assets held for sale given it will be retained and settled by NN, Inc.
