Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Tax Act, enacted December 22, 2017, reduced the corporate tax rate, limited or eliminated certain tax deductions, and changed the taxation of foreign earnings of U.S. multinational companies. The enacted changes include a mandatory income inclusion of the historically untaxed foreign earnings of a U.S. company’s foreign subsidiaries and will tax such income at reduced tax rates (“mandatory deemed repatriation tax”). During the second quarter of 2018, the Company made reasonable estimates related to certain impacts of the Tax Act and, in accordance with SAB 118, recorded a provisional income tax expense of $30.9 million. This provisional expense is mainly comprised of the one-time mandatory deemed repatriation tax that will be paid over eight years as well as the re-measurement of the Company’s U.S. deferred tax attributes. The calculation of the mandatory deemed repatriation tax is based upon preliminary estimates of post-1986 earnings and profits and tax pools, utilization of U.S. federal net operating losses and tax credits, and the amounts of foreign earnings held in cash and non-cash assets. As of May 31, 2018, the Company continues to believe $30.9 million is a reasonable estimate related to Tax Reform based on the analyses, interpretations and guidance available at this time. As a result of the mandatory deemed repatriation tax, the Company will have a substantial amount of previously taxed earnings that can be distributed to the U.S. without additional U.S. taxation. Additionally, the Tax Act provides for a 100% dividends received deduction for dividends received by U.S. corporations from 10-percent or more owned foreign corporations. Therefore, the Company is analyzing its indefinite reinvestment assertion and cash repatriation plan. The Company has made no adjustments to its financial statements in the current quarter with respect to its indefinite reinvestment assertion, but may do so during the measurement period. A change in assertion could result in a material deferred tax liability associated with foreign withholding taxes that would be incurred upon such future remittances of cash. Additionally, the Company is still evaluating the Global Intangible Low-Taxed Income ("GILTI") provisions and the associated election to record its effects as a period cost or a component of deferred taxes. The final impact of the Tax Act may differ from the Company’s estimates due to, among other items, additional regulatory guidance that may be issued, changes in interpretations and assumptions, and finalization of calculations of the impact of the Tax Act, including the on-going analysis of U.S. tax attributes, re-measurement of the Company's U.S. deferred tax attributes and the computation of earnings and profits and tax pools of the Company’s foreign subsidiaries. The Company also continues to evaluate its indefinite reinvestment assertion regarding undistributed earnings and profits as a result of the Tax Act. As the Company finalizes the accounting for the tax effects of the enactment of the Tax Act during the measurement period, the Company will reflect adjustments to the provisional amounts recorded and record additional tax effects in the periods such adjustments are identified. The Company has not completed its accounting for any aspect of the Tax Act. As a result of the Tax Act, the Company will be subject to a blended U.S. federal tax rate of 25.7% for the current fiscal year and a 21.0% U.S. federal tax rate for future years. The effective tax rate differed from the blended U.S. federal statutory rate of 25.7% during the nine months ended May 31, 2018 primarily due to the Tax Act, including the one-time mandatory deemed repatriation tax and the re-measurement of the Company’s U.S. deferred tax attributes of $30.9 million, partially offset by a reduction in unrecognized tax benefits of $16.1 million for the lapse of statute in a non-U.S. jurisdiction. Other primary drivers for the difference between the effective tax rate and the blended U.S. federal statutory rate of 25.7% during the three months and nine months ended May 31, 2018 and 2017 are: (i) tax incentives granted to sites in Brazil, China, Malaysia, Singapore and Vietnam; and (ii) losses in tax jurisdictions with existing valuation allowances, including losses from stock-based compensation for the nine months ended May 31, 2018 and losses from restructuring costs for the three months and nine months ended May 31, 2017.
