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 FIN 48 unrecognized tax benefits nor any accrued interest or penalties associated with unrecognized tax benefits during the six months ended December 31, 2013. 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 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. 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”), which creates 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 six months ended December 31, 2013 does not include the utilization of statutory depletion deductions in excess of basis carried over from previous years that had driven our book tax rate well below statutory rates during the three months ended September 30, 2013. Instead our tax benefits were changed significantly during November and December 2013 when our employees, officers and directors exercised more than 4 million of 4.8 million stock options and incentive warrants, resulting in approximately $31.2 million of tax deductions (“Option Deductions”) available to us resulting in a tax impacted benefit of approximately $10.6 million assuming a 34% statutory rate. On a financial reporting basis this is expected to result in a tax benefit associated with stock compensation (i.e. windfall tax benefit) to the extent of expected cash income taxes payable generated in fiscal year 2014. The remainder of the Option Deductions result in an unbenefitted net operating loss associated with stock compensation to benefit future fiscal years. To the extent the Option Deductions cause a net operating loss, no deferred tax asset is recorded under the rules of ASC 718. The Option Deductions will be recorded as a reduction in current income taxes payable each year and an increase in equity to the extent cash taxes payable are reduced to zero. Because the Option Deductions are expected to reduce taxable income to zero for the year ended June 30, 2014, percentage depletion is no longer available for the current year, thus negating the beneficial rate reduction for the percentage depletion in excess of basis. Percentage depletion that is no longer expected to be deductible in 2014, will be carried forward to future years. The Option Deductions will only impact reported earnings by increasing the projected effective tax rate closer to the statutory rate in those years affected by the Option Deductions due to percentage depletion in excess of basis deduction being delayed and carried forward. Our effective annual tax rate estimated as December 31, 2013 was impacted by this postponement of depletion in excess of basis. Our estimated annual income tax rate used to determine income tax expense for the three months ended September 30, 2013 included 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 which has been reversed in the current fiscal quarter. We recognized income tax expense of $724,543 and $1,814,717 for the six months ended December 31, 2013 and 2012, respectively, with corresponding effective rates of 41% and 37%.

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 FIN 48 unrecognized tax benefits nor any accrued interest or penalties associated with unrecognized tax benefits during the six months ended December 31, 2013. 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 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.

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”), which creates 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 six months ended December 31, 2013 does not include the utilization of statutory depletion deductions in excess of basis carried over from previous years that had driven our book tax rate well below statutory rates during the three months ended September 30, 2013.
