Income Taxes	3 Months Ended
Mar. 31, 2019
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We recognized a federal and state income tax benefit for the three months ended March 31, 2019 at the blended rate of 21.5%; however, the federal and state tax expense was offset by an adjustment to the valuation allowance against our net deferred tax assets resulting in an effective tax rate of less than 0.1%. The effect of this adjustment, as well as a reclassification of $1.2 million from deferred tax assets to the current income tax receivable for refundable alternative minimum tax (“AMT”) credit carryforwards, was to reduce our deferred tax asset to $0.7 million as of March 31, 2019. We recognized a federal income tax expense for the three months ended March 31, 2018 at the blended rate of 21.6% which was similarly offset by a valuation allowance against our net deferred tax assets, along with an adjustment of $0.2 million to the deferred tax asset related to sequestration of a portion of the aforementioned AMT credit carryforward resulting in an effective tax rate of 1.6%. We considered both the positive and negative evidence in determining that it was more likely than not that some portion or all of our deferred tax assets will not be realized, primarily as a result of cumulative losses. We had no liability for unrecognized tax benefits as of March 31, 2019. There were no interest and penalty charges recognized during the periods ended March 31, 2019 and 2018. Tax years from 2014 forward remain open to examination by the major taxing jurisdictions to which the Company is subject; however, net operating losses originating in prior years are subject to examination when utilized.
