The effective tax rate for the three and six months ended June 30, 2022 differs from the U.S. federal statutory rate of 21%, primarily due to the tax benefit for excess percentage depletion and foreign derived intangible income, partially offset by tax expense related to compensation.

These tax provision amounts also included discrete tax adjustments related to prior years' taxes, state tax law changes and equity compensation.

Due to the expectation of taxable income for the year 2022, the Company has recognized a benefit related to the release of a valuation allowance for state tax net operating losses in its annual effective tax rate for the six months ended June 30, 2022, which resulted in a less than 1% decrease to the Company's annual effective tax rate.

The Company is subject to taxation in the United States and its various states, as well as Canada and its various provinces. The Company is subject to examination for the tax periods 2018 through 2021 for federal and state returns.
