Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective tax rate used for interim periods is the estimated annual effective consolidated tax rate, based on the current estimate of full year results, except that taxes related to specific events, if any, are recorded in the interim period in which they occur. The annual effective tax rate is based upon a number of significant estimates and judgments, including the estimated annual pre-tax income of the Company in each tax jurisdiction in which it operates, and the development of tax planning strategies during the year. In addition, the Company’s tax expense can be impacted by changes in tax rates or laws, the finalization of tax audits, and other factors that cannot be predicted with certainty. As such there can be significant volatility in interim tax provisions. Income tax expense for the three months ended September 30, 2018 was $8.8 million, or 21.8 percent of pre-tax income as compared with $11.8 million, or 33.5 percent of pre-tax income for the three months ended September 30, 2017. An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018 (the “Act”) was enacted on December 22, 2017. The Act included provisions that reduced the federal corporate income tax rate, created a territorial tax system with a one-time mandatory tax on previously deferred foreign earnings (i.e. transition tax), and changed certain business deductions including allowing for immediate expensing of certain qualified capital expenditures and limitations on deductions of interest expense. The permanent reduction to the U.S. federal corporate income tax rate from 35 percent to 21 percent was effective January 1, 2018. Based on the Company's interpretation of the Act, during fiscal year 2018, the Company recorded a provisional tax charge of $5.0 million for the transition tax and a provisional tax benefit of $74.6 million for the re-measurement of deferred tax assets and liabilities. The Company determined that the amounts recorded during fiscal year 2018 for the transition tax are provisional because various components of the computation are not yet finalized as of September 30, 2018, including the following significant items: the actual aggregate foreign cash position and the earnings and profits of the foreign entities as of June 30, 2018, the interpretation and identification of cash positions as of June 30, 2018, and computations of accumulated earnings and profits balances as of November 2, 2017 and December 31, 2017. Under the Act, the transition tax will be paid over an eight-year period beginning in fiscal year 2019. The Company also determined that the re-measurement of deferred tax assets and liabilities at the lower federal corporate income tax rate is provisional until such time that the underlying temporary differences are known rather than estimated. Future adjustments to the provisional amounts related to the Act will be recorded as discrete adjustments to income tax expense in the period in which those adjustments are determined. Prior to the Act, undistributed earnings of foreign subsidiaries, totaling $93.8 million, were considered permanently reinvested. The Company is in the process of evaluating its assertion for indefinite reinvestment. The Act also established new tax provisions that become effective in fiscal year 2019, including but not limited to eliminating the corporate alternative minimum tax, creating the base erosion anti-abuse tax (“BEAT”), establishing new limitations on deductible interest expense and certain executive compensation, creating a new provision designed to tax global intangible low-tax income (“GILTI”) and generally eliminating U.S. Federal income taxes on dividends from foreign subsidiaries. The Company does not anticipate being subject to the BEAT provision due to the revenue thresholds. An accounting policy election must be made to either treat taxes due on future GILTI inclusions in U.S. taxable income as a current period expense when incurred or reflect such portion of the future GILTI inclusions in U.S. taxable income that relate to existing basis differences in the Company’s current measurement of deferred taxes. The Company has treated the GILTI inclusion in U.S. taxable income as a current period expense in its annual effective tax rate for fiscal year 2019 but continues to analyze the new GILTI rules and its impacts before finalizing its policy election.
