| Income Tax Disclosure                | INCOME TAXESWe evaluate our estimated annual effective income tax rate on a quarterly basis based on current and forecasted operating results and tax laws. The estimated annual effective tax rate is adjusted quarterly based upon actual results and updated operating forecasts. Consequently, based upon the mix and timing of our actual earnings compared to annual projections, our effective tax rate may vary quarterly and may make quarterly comparisons not meaningful. A tax expense or benefit unrelated to the current year income or loss is recognized in its entirety as a discrete item of tax in the period identified. The quarterly income tax provision is generally comprised of tax expense on income or tax benefit on loss at the most recent estimated annual effective tax rate, adjusted for the effect of discrete items.The effective tax rate for continuing operations for the three months ended March 31, 2014 was a 39.5% benefit on loss compared to a 35.5% benefit on loss for the three months ended March 31, 2013. The effective tax rate for the three months ended March 31, 2014 is based upon a full year forecasted tax provision on income and is greater than the statutory rate primarily due to nondeductible officers' compensation, partially offset by percentage depletion deductions. For the three months ended March 31, 2013, the nondeductible item for officers' compensation exceeded our deduction for percentage depletion, thereby reducing our tax benefit rate. Additionally, state statutory limits on the utilization of our net operating losses resulted in a reduced state tax benefit for the three months ended March 31, 2013. There were no significant discrete items recorded during the three months ended March 31, 2014 or 2013.As of March 31, 2014, our gross liability for unrecognized tax benefits continues to be immaterial and was unchanged from the amount recorded at December 31, 2013. We expect our remaining liability for uncertain tax positions to decrease to zero in the next 12 months due to the expiration of the statute of limitations.As of the date of this report, we are current with our income tax filings in all applicable state jurisdictions and are not currently under examination.  We continue voluntary participation in the Internal Revenue Service’s Compliance Assurance Program for the 2013 and 2014 tax years.  We received a full acceptance “no change” notice from the IRS for our filed 2012 federal tax return. |
