Income Tax Disclosure [Abstract]
Income Taxes	6—INCOME TAXES Effective Tax Rates The Company’s effective tax rate for the first quarter of fiscal 2013 was 38.5%. The difference between the effective tax rate and the U.S. federal statutory tax rate was primarily due to state income taxes. The Company’s effective tax rate for the first quarter of fiscal 2012 was 70%. The difference between the effective tax rate and the U.S. federal statutory tax rate was primarily due to state income taxes and dividends and accretion of discount on the Company’s 15% Series A Preferred Stock. The dividends and accretion of discount were reported as interest expense in the Condensed Consolidated Statements of Operations but were not deductible for tax return purposes. Valuation Allowance In fiscal 2012, the Company recorded a $1.8 million valuation allowance primarily related to small ethanol producer tax credit carryforwards which expire in fiscal 2014. Tax laws require that any net operating loss carryforwards be utilized before the Company can utilize the small ethanol producer tax credit carryforwards. Due to the near-term expiration of the small ethanol producer tax credit carryforward period, the Company does not believe it has sufficient positive evidence to substantiate that the small ethanol tax credit carryforwards are realizable at a more-likely-than-not level of assurance and recorded a $1.8 million valuation allowance. The valuation allowance will be reversed in future periods if these tax credit carryforwards are utilized. There was no change in the valuation allowance in the first quarter of fiscal 2013. At November 30, 2012, the Company had $13.3 million of net deferred tax assets. Other than for the ethanol tax credit carryforwards discussed above, a valuation allowance has not been provided on the net U.S. deferred tax assets as of November 30, 2012. The determination of the need for a valuation allowance requires significant judgment and estimates. The Company evaluates the requirement for a valuation allowance each quarter. The Company believes that it is more likely than not that future operations and the reversal of existing taxable temporary differences will generate sufficient taxable income to realize its deferred tax assets, except for the small ethanol producer tax credit carryforwards, for which a valuation allowance has been provided. Uncertain Tax Positions In the quarter ended November 30, 2012, the amount of unrecognized tax benefits increased by approximately $43,000. The total amount of unrecognized tax benefits at November 30, 2012 was $1.1 million, all of which, if recognized, would favorably impact the effective tax rate. At November 30, 2012, the Company had $0.2 million of accrued interest and penalties included in the long-term tax liability. Other The Company files tax returns in the U.S. federal jurisdiction and various U.S. state jurisdictions, and is subject to examination by taxing authorities in all of those jurisdictions. From time to time, the Company’s tax returns are reviewed or audited by U.S. federal and various U.S. state taxing authorities. The Company believes that adjustments, if any, resulting from these reviews or audits would not be material, individually or in the aggregate, to the Company’s financial position, results of operations or liquidity. It is reasonably possible that the amount of unrecognized tax benefits related to certain of the Company’s tax positions will increase or decrease in the next twelve months as audits or reviews are initiated and settled. At this time, an estimate of the range of a reasonably possible change cannot be made. The Company is not subject to income tax examinations by U.S. federal or state jurisdictions for fiscal years prior to 2007.
