Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes We file a consolidated federal income tax return in the United States and various combined and separate filings in several state and local jurisdictions. There were neither unrecognized tax benefits nor any accrued interest or penalties associated with unrecognized tax benefits during any periods presented in the financial statements. We believe we have appropriate support for the income tax positions taken and to be taken on our tax returns and that the accruals for tax liabilities are adequate for all open years based on our assessment of various factors including past experience and interpretations of tax law applied to the facts of each matter. The Company’s federal and state income tax returns are open to audit under the statute of limitations for the years ended June 30, 2015 through June 30, 2018 for federal tax purposes and for the years ended June 30, 2014 through June 30, 2018 for state tax purposes. To the extent we utilize net operating losses generated in earlier years, such earlier years may also be subject to audit. For the six months ended December 31, 2018 and 2017, respectively, we recognized income tax expense of $2.2 million and an income tax benefit of $(4.7) million. This benefit included a one-time $6.0 million tax credit, resulting from adjustment of our deferred income tax liabilities at December 31, 2017 in connection with enactment of the Tax Cut and Jobs Act (the "Tax Act"). For the six months ended December 31, 2018 and 2017, the corresponding effective tax rates were 18% and (63)%. Excluding the effect of the $6.0 million tax credit, income tax as a percentage of income before income taxes would have been approximately 19% for the six months ended December 31, 2017. Our effective tax rate will typically differ from the statutory federal rate as a result of state income taxes, primarily in the State of Louisiana, and differences related to percentage depletion in excess of basis, stock-based compensation and other permanent differences. For the six months ended December 31, 2018 and 2017, our respective statutory federal tax rates were 21% and 27.55%, as we used a blended rate during our fiscal year in which the Tax Act was enacted. The benefit of this statutory rate reduction was partially offset by a decreased benefit from depletion in excess of basis as much of our depletion carryover had been utilized in fiscal 2018.
