Income Taxes	6 Months Ended
Income Taxes	Apr. 30, 2021
Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Our quarterly tax provision is calculated using an estimated annual tax rate that is adjusted for discrete items occurring during the period to arrive at our effective tax rate. During the three and six months ended April 30, 2021, we had effective tax rates of 27.3% and 26.9%, respectively, resulting in provisions for taxes of $11.7 million and $38.9 million, respectively. During the three and six months ended April 30, 2020, we had effective tax rates of (8.4)% and (21.4)%, respectively, resulting in provisions for taxes of $10.6 million and $19.2 million, respectively. The effective tax rate for the three and six months ended April 30, 2020, excluding an impairment loss of non-deductible goodwill of $163.8 million, was 28.1% and 25.9% respectively. The difference between the effective tax rate and statutory rate is primarily related to tax credits. The rate difference between periods is driven by increased income in 2021. Our effective tax rate for the three months ended April 30, 2021 was not impacted by any significant discrete items. Our effective tax rate for the three months ended April 30, 2020 was impacted by an impairment loss of non-deductible goodwill as described in Note 5. Our effective tax rate for the six months ended April 30, 2021 was not impacted by any significant discrete items. Our effective tax rate for the six months ended April 30, 2020 was impacted by an impairment loss of non-deductible goodwill as described in Note 5 and a $1.5 million tax provision related to the Work Opportunity Tax Credit (“WOTC”). In response to COVID-19, Congress enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) on March 27, 2020. The CARES Act provides various tax provisions, including payroll tax provisions, which we have evaluated for applicability. Through December 31, 2020, we deferred approximately $132 million of payroll tax, which the CARES Act requires to be remitted in equal parts by December 31, 2021 and December 31, 2022. The impact of the income tax provisions was not material. We plan to reinvest our foreign earnings to fund future non-U.S. growth and expansion, and we do not anticipate remitting such earnings to the United States. While U.S. federal tax expense has been recognized as a result of the Tax Cuts and Jobs Act of 2017, no deferred tax liabilities with respect to federal and state income taxes or foreign withholding taxes have been recognized.
