Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three month period ended September 30, 2017, the Company recorded a provision for income taxes of $31,924 (effective rate of 33.8 percent) compared with $23,757 (effective rate of 32.0 percent) for the comparable period in 2016. For the nine month period ended September 30, 2017, the Company recorded a provision for income taxes of $67,250 (effective rate of 32.8 percent) compared with $86,509 (effective rate of 32.4 percent) for the comparable period in 2016. The 2017 three and nine month period provision for income taxes is calculated using the forecasted multi-jurisdictional annual effective tax rates to determine a blended annual effective tax rate. The effective tax rate for the three month period ended September 30, 2017 differs from the U.S. federal statutory rate of 35 percent primarily due to the projected mix of earnings in international jurisdictions with lower tax rates, partially offset by losses in jurisdictions where valuation allowances are recorded. The effective tax rate for the nine month period ended September 30, 2017 differs from the U.S. federal statutory rate of 35 percent primarily due to the projected mix of earnings in international jurisdictions with lower tax rates, partially offset by losses in jurisdictions where valuation allowances are recorded, and due to a discrete tax benefit recognized as a result of the adoption of ASU 2016-09, "Improvements to Employee Share-Based Accounting," which requires all excess tax benefits or deficiencies from share-based payments to be recognized as income tax expense or benefit in the income statement. For the quarter and nine month periods ended September 30, 2017, the Company recognized excess tax benefits from share-based payments of $85 and $2,024, respectively. The Company continues to maintain a valuation allowance pursuant to ASC 740, “Accounting for Income Taxes,” against portions of its U.S. and non-U.S. deferred tax assets at September 30, 2017, 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 a portion of its deferred tax asset relating primarily to a loss carryforward by a valuation allowance of $2,350. In addition, the Company has recorded valuation allowances of $18,497 relating to non-U.S. net operating losses and other deferred tax assets for a total valuation allowance of $20,847. 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. The Company maintains an ASC 740-10, “Accounting for Uncertainty in Income Taxes,” liability for unrecognized tax benefits for permanent and temporary differences. At September 30, 2017, the Company’s liability, exclusive of interest, totals approximately $2,266. The Company accrued an immaterial amount of interest expense related to these unrecognized tax benefits during the quarter and nine month periods ended September 30, 2017. Based upon the outcome of tax examinations, judicial proceedings, or expiration of statutes of limitations, it is possible that the ultimate resolution of these unrecognized tax benefits may result in a payment that is materially different from the current estimate of the tax liabilities. The Company and its subsidiaries are subject to income tax examination in the U.S. federal jurisdiction and various state and foreign jurisdictions. The Company has effectively settled U.S. federal tax examinations for years before 2014 and state and local examinations for years before 2013, with limited exceptions. Non-U.S. subsidiaries of the Company are no longer subject to income tax examinations in major foreign taxing jurisdictions for years prior to 2008. The income tax returns of various subsidiaries in various jurisdictions are currently under examination and it is possible that these examinations will conclude within the next twelve months. However, it is not possible to estimate net increases or decreases to the Company’s unrecognized tax benefits during the next twelve months.
