(1)In the three and six months ended May 31, 2023, the Company's overall effective income tax rate was lower than during the three and six months ended May 31, 2022, primarily due to the reinstatement of the new energy efficient home credit as a result of the enactment of the Inflation Reduction Act during the third quarter of 2022. For both the three and six months ended May 31, 2023 and 2022, the effective tax rate included state income tax expense and non-deductible executive compensation, partially offset by energy efficient home and solar tax credits.
