Income Taxes [Abstract]  
Income Tax Disclosure [Text Block] Income Taxes
The effective income tax rate for the three and six months ended January 31, 2021, was 20.8% and 20.6%, respectively. The Company expects its ongoing annual effective income tax rate to approximate 20% based on its current global business mix and based on current tax laws and statutory tax rates in effect.
The effective income tax rate for the three and six months ended January 31, 2020, was 20.8% and 15.3%, respectively. The effective income tax rate for the six months ended January 31, 2020 was lower than the expected income tax rate due to the favorable settlement of a domestic income tax audit and tax benefits from stock-based compensation.
