NOTE 11 - INCOME TAXES
Our 2021 estimated annual effective tax rate before discrete items as of June 30, 2021 is 21%. The estimated annual effective tax rate mirrors the U.S. statutory rate of 21%, as the adjusting items, including percentage depletion in excess of cost depletion, net to zero. The 2020 estimated annual effective tax rate before discrete items as of June 30, 2020 was 31%. The decrease in the estimated annual effective tax rate before discrete items is driven by the change in income.
