Jan. 31, 2020
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective income tax rate for the three- and nine-month periods ended January 31, 2020 was 25.9% and 26.0%, respectively, compared with 23.7% and 24.9% in the comparable periods in the prior fiscal year. The increase in the effective tax rate for the third quarter as compared to the comparable period in the prior fiscal year was primarily due to benefits from credits finalized with the filing of the fiscal 2018 tax return in the prior year. The overall increase in the effective tax rate for the first nine months of fiscal 2020, as compared to the comparable period in the prior year, was primarily due to a decrease in the benefit from stock-based compensation transactions and benefits from credits finalized with the filing of the fiscal 2018 tax return during fiscal 2019.
