NOTE 11 - INCOME TAXES
Our 2022 estimated annual effective tax rate before discrete items as of MarchÌý31, 2022 is 22%. The estimated annual effective tax rate exceeds the U.S. statutory rate of 21%, as state income tax expense exceeds the percentage depletion in excess of cost depletion. The 2021 estimated annual effective tax rate before discrete items as of MarchÌý31, 2021 was 19%. The increase in the estimated annual effective tax rate before discrete items is driven by the change in income and a decrease to the percentage depletion in excess of cost depletion.
