Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXESThe Company calculates the provision for income taxes during interim reporting periods by applying an estimate of the annual effective tax rate to its year-to-date pretax book income or loss. The tax effects of discrete items, including but not limited to, excess tax benefits associated with stock-based compensation, valuation allowance adjustments based on new evidence and enactment of tax laws, are reported in the interim period in which they occur. The effective tax rate (income taxes as a percentage of income or loss before income taxes) including discrete items was 21.8% for the three months ended March 31, 2021, as compared to 0.0% for the three months ended March 31, 2020, due to a full valuation allowance as of March 31, 2020. Our effective income tax rate can vary from period to period depending on, among other factors, percentage depletion, executive compensation deduction limitations, other permanent book/tax items, and changes to our valuation allowance, if any. Certain of these and other factors, including our history and projections of pretax earnings, are considered in assessing our ability to realize our net deferred tax assets.
