Income Taxes	Income Taxes The effective income tax rates for the three-month period ended July 31, 2023 was 21.9% compared with 25.0% in the comparable period in the prior fiscal year. The effective rates were higher than the 21.0% U.S. statutory rate for all periods presented primarily due to state income taxes. The effective rate for the period ended July 31, 2023 was lower than the comparable period in the prior fiscal year primarily due to a favorable increase in federal tax credits for prior periods and stock compensation deductions booked in the current quarter.
