Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective tax rate for the periods presented was primarily the result of income earned in the U.S., taxed at U.S. federal and state statutory income tax rates, income earned in foreign tax jurisdictions taxed at the applicable rates, as well as the impact of permanent differences between book and tax income. On December 22, 2017, the President of the United States signed into law Public Law No. 115-97, commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”), following its passage by the United States Congress. The Tax Act made significant changes to U.S. federal income tax laws, including reduction of the corporate tax rate from 35.0% to 21.0%, and the implementation of a territorial tax system resulting in a one-time transition tax on the unremitted earnings of our foreign subsidiaries. The Tax Act also contains additional provisions that are effective for us in fiscal year 2019, including a new deduction for Foreign-Derived Intangible Income (“FDII”), the repeal of the domestic production activity deduction, a new tax on Global Intangible Low-Taxed Income (“GILTI”), and increased limitations on the deductibility of certain executive compensation. Our effective tax rate was 18.2% and 14.7% during the three and nine months ended March 31, 2019, respectively, and 23.7% and (41.5)% during the three and nine months ended March 31, 2018, respectively. Our effective tax rate decreased for the three months ended March 31, 2019 compared to the same period in 2018 primarily due to a reduction in the statutory tax rate from 28.1% to 21.0%. Our effective tax rate increased for the nine months ended March 31, 2019 compared to the same period in 2018 due to the tax benefit recorded for the revaluation of our deferred tax liabilities resulting from the adoption of Topic 606. We adopted Topic 606 effective July 1, 2018 using the full retrospective method, following the reduction of federal income tax rates due to the enactment of the Tax Act. The reduction in the corporate tax rate from 35.0% to the blended tax rate of 28.1% reduced our deferred tax liabilities established under Topic 606, which resulted in an income tax benefit for the nine months ended March 31, 2018. During the three and nine months ended March 31, 2019, our income tax expense was driven primarily by pre-tax profitability in our domestic and foreign operations and the impact of permanent items. The permanent items are predominantly the FDII deduction and tax credits for research expenditures. The Tax Act has several significant changes that impact all taxpayers, including a transition tax, which is a one-time tax charge on accumulated, undistributed foreign earnings. The calculation of accumulated foreign earnings requires an analysis of each foreign entity’s financial results going back to 1986. We have concluded that we will not be subject to the transition tax associated with our accumulated, undistributed foreign earnings. We do not provide deferred taxes on unremitted earnings of our foreign subsidiaries as we intend to indefinitely reinvest those earnings. The Tax Act also included a new provision designed to tax global intangible low-taxed income (“GILTI”). Under U.S. GAAP, we are allowed to make an accounting policy choice to either (i) treat taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the "period cost method"); or (ii) factor in such amounts into the measurement of our deferred taxes (the "deferred method"). Our selection of an accounting policy related to the GILTI tax provisions depends, in part, on analyzing our global income to determine whether we expect to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. While our future global operations depend on a number of different factors, we do expect to have future U.S. inclusions in taxable income related to GILTI. Further, we have made a policy decision to record GILTI tax as a current-period expense when incurred. Deferred income taxes are recognized based on temporary differences between the financial statement and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using the statutory tax rates and laws expected to apply to taxable income in the years in which the temporary differences are expected to reverse. Valuation allowances are provided against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income and the timing of the temporary differences becoming deductible. Management considers, among other available information, scheduled reversals of deferred tax liabilities, projected future taxable income, limitations of availability of net operating loss carryforwards, and other matters in making this assessment.
