Income Tax Disclosure [Abstract]
Income taxes	Income taxes For the three month period ended March 31, 2021, the Company recorded income tax expense of $8,544 (effective tax rate of 27.9 percent) compared to an income tax benefit of $659 (effective tax rate of 5.5 percent) for the same period in 2020. The Company's 2021 and 2020 three month period provisions for income tax are calculated using a forecasted multi-jurisdictional annual effective tax rate to determine a blended annual effective tax rate. The Company is subject to the U.S. federal statutory rate of 21 percent. The effective tax rate for the three month period ended March 31, 2021 was influenced by $4,923 of Merger-related costs which are not tax deductible, the projected mix of earnings in international jurisdictions with differing tax rates and jurisdictions where valuation allowances are recorded. The effective tax rate for the three month period ended March 31, 2020 was impacted by $4,361 of unrecognized tax benefit related to the tax deductibility of certain business expenses incurred during the quarter, the projected mix of earnings in international jurisdictions with differing tax rates and jurisdictions where valuation allowances are recorded. The Company continues to maintain valuation allowances pursuant to ASC 740, “Accounting for Income Taxes,” against portions of its U.S. and non-U.S. deferred tax assets at March 31, 2021 as it cannot assure the future realization of the associated tax benefits prior to their reversal or expiration. In the U.S., the Company has offset its net operating loss carryforward deferred tax asset by a valuation allowance of $1,503. In addition, the Company has recorded valuation allowances of $33,841 related to non-U.S. net operating losses and other deferred tax assets for a total valuation allowance of $35,344. In conjunction with the Company’s ongoing review of its actual results and anticipated future earnings, the Company will continue to reassess the possibility of releasing all or part of the valuation allowances currently in place when the associated deferred tax assets are deemed to be realizable. If the evidence suggests that deferred tax assets for these operations will more likely than not be able to be realized in the future, release of a portion or all of the valuation allowance in place for these entities could occur. Such release could materially impact the Company's effective tax rate in the period in which the release occurs. The Company maintains an ASC 740-10, “Accounting for Uncertainty in Income Taxes,” liability for unrecognized tax benefits. At March 31, 2021, the liability, exclusive of penalty and interest, totals approximately $12,890. During the three month period ended March 31, 2021, an immaterial amount of interest expense was accrued. The Company operates in multiple jurisdictions throughout the world and has effectively settled U.S. federal income tax examinations for tax years before 2017, state and local income tax examinations for tax years before 2015 (with limited exceptions), and income tax examinations in its major foreign taxing jurisdictions for tax years before 2015. Based upon the outcome of tax examinations, judicial proceedings, or expiration of statutes of limitations, it is possible that the ultimate resolution of the Company's unrecognized tax benefits may result in a payment that is materially different from the current estimate of the tax liabilities.
