Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On December 22, 2017, the Tax Cuts and Jobs Act was signed into law. The Tax Cuts and Jobs Act, among other things, reduced the U.S. federal corporate tax rate from 35% to 21% and imposed a new minimum tax on Global Intangible Low-Taxed Income ("GILTI") earned by foreign subsidiaries. In July 2020, final regulations were issued for GILTI, which include a high-tax exception for certain income earned by foreign subsidiaries if the foreign tax rate is in excess of 90% of the U.S. corporate tax rate of 21%. We calculated the potential impact of these final regulations and accounted for those impacts in the quarterly provision for the period ended September 30, 2020. Income taxes are recorded in our quarterly financial statements based on our estimated annual effective income tax rate, subject to adjustments for discrete events, should they occur. The effective tax rates used in the calculation of income taxes were 14.1% and 24.5% for the three months ended September 30, 2020 and 2019, respectively. The effective tax rates used in the calculation of income taxes were 19.8% and 25.4% for the six months ended September 30, 2020 and 2019, respectively. The decrease in the effective tax rate for the six months ended September 30, 2020 versus the prior year period was primarily due to the final GILTI regulations issued in July 2020, which resulted in the release of the valuation allowance on foreign tax credit carryforwards of $5.1 million.
