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 the nine months ended March 31, 2017. 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, 2013 through June 30, 2016 for federal tax purposes and for the years ended June 30, 2011 through June 30, 2016 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. We recognized income tax expense of $3,768,463 and $2,051,521 for the nine months ended March 31, 2017 and 2016, respectively, with corresponding effective tax rates of 37% and 35%. 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. The effective tax rate for the nine months ended March 31, 2017 was slightly higher than the statutory federal rate as a result of state income taxes and the tax effects of stock-based compensation, offset by percentage depletion in excess of basis.
