NOTE 9—INCOME TAXES

Income tax provisions for interim quarterly periods are generally based on an estimated annual effective income tax rate calculated separately from the effect of significant, infrequent or unusual items related specifically to interim periods. The income tax impact of discrete items are recognized in the period these occur.

Discrete items during the three months ended March 31, 2021 included the impact of legislative changes in West Virginia. Excluding discrete items, our effective tax rate for the three months ended March 31, 2022 and March 31, 2021 was 19.5% and 5%, respectively. The primary difference from the federal statutory rate of 21% in each period is related to state taxes, permanent differences for non-deductible expenses and depletion expense for income tax purposes.
