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, 2022 was lower than the comparable period in the prior fiscal year primarily due to more favorable permanent tax differences in the current year.
