Income Taxes	Note 8 —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 no unrecognized tax benefits nor any accrued interest or penalties associated with unrecognized tax benefits during the three months ended September 30, 2013. We believe that we have appropriate support for the income tax positions taken and to be taken on the Company’s tax returns and that the accruals for tax liabilities are adequate for all open years based on our assessment of many 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 ending June 30, 2009 through June 30, 2012. The Company recognized income tax expense of $482,636 and $760,218 for the three months ended September 30, 2013 and 2012, respectively, with corresponding effective rates of 24.7% and 39.6%. Our effective tax rate for any period may differ from the statutory federal rate due to (i) our state income tax liability in Louisiana, (ii) stock-based compensation expense related to qualified incentive stock option awards (“ISO awards”), both of which create a permanent tax difference for financial reporting, as these types of awards, if certain conditions are met, are not deductible for federal tax purposes, and (iii) statutory percentage depletion, which may create a permanent tax difference for financial reporting. Our estimated annual income tax rate used to determine income tax expense for the three months ended September 30, 2013 includes the utilization of statutory depletion deductions carried over from previous years resulting in a higher than normal rate benefit from depletion in excess of basis.
