Income Tax Disclosure [Abstract]
Income Taxes	8. Income Taxes The provision for income tax was an expense of $8.8 million and $39.0 million in the three and nine months ended January 31, 2020, respectively, resulting in a 29.5% and 26.6% effective tax rate, respectively. In both periods, the Company’s effective tax rate was higher than the U.S. federal statutory rate of 21.0% primarily due to the impact of U.S. state income taxes and the recognition of taxable income outside the U.S. at higher statutory tax rates.
