Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s income tax benefit totaled $10.7 million for the three months ended August 31, 2012. The income tax benefit primarily reflected the resolution of a federal tax audit, which resulted in an income tax benefit of $10.8 million and the realization of $1.1 million of deferred tax assets during the three months ended August 31, 2012. As a result of the resolution of the federal tax audit, the Company received approximately $1.8 million of income tax refunds during the third quarter of 2012, and reflected a receivable of $10.1 million on its consolidated balance sheet as of August 31, 2012. The $10.1 million was received in the fourth quarter of 2012. The Company had no income tax benefit or expense for the three months ended August 31, 2011. For the nine months ended August 31, 2012, the Company’s income tax benefit totaled $14.8 million, compared to income tax expense of $.1 million for the nine months ended August 31, 2011. The income tax benefit for the nine months ended August 31, 2012 primarily resulted from the resolution of the federal tax audit described above and a $4.1 million state income tax refund received in the second quarter in connection with the resolution of a state tax audit. Due to the effects of its deferred tax asset valuation allowance and changes in its unrecognized tax benefits, the Company’s effective tax rates for the three months and nine months ended August 31, 2012 and 2011 are not meaningful items as the Company’s income tax amounts are not directly correlated to the amount of its pretax losses for those periods. In accordance with Accounting Standards Codification Topic No. 740, “Income Taxes” (“ASC 740”), the Company evaluates its deferred tax assets quarterly to determine if adjustments to the valuation allowance are required. ASC 740 requires that companies assess whether a valuation allowance should be established based on the consideration of all available evidence using a “more likely than not” standard with respect to whether deferred tax assets will be realized. The realization of deferred tax assets depends primarily on the Company’s ability to generate sustained profitability. During the three months ended August 31, 2012, the Company recorded a valuation allowance of $7.1 million against net deferred tax assets generated from the pretax loss for the period and other adjustments due to the resolution of the federal tax audit. During the three months ended August 31, 2011, the Company recorded a similar valuation allowance of $2.5 million against net deferred tax assets generated from the pretax loss for the period. For the nine months ended August 31, 2012 and 2011, the Company recorded valuation allowances of $35.1 million and $73.3 million, respectively, against the net deferred tax assets generated primarily from the pretax losses for those periods. As a result of the resolution of the federal tax audit described above, the Company had no net deferred tax assets at August 31, 2012, compared to net deferred tax assets of $1.1 million at November 30, 2011. The deferred tax asset valuation allowance increased to $882.9 million at August 31, 2012 from $847.8 million at November 30, 2011, reflecting the $35.1 million valuation allowance recorded during the nine months ended August 31, 2012. During the three months ended August 31, 2012, the Company had no change in its total gross unrecognized tax benefits. During the nine months ended August 31, 2012, the Company had a net reduction in its total gross unrecognized tax benefits of $.4 million as a result of the current status of federal and state tax audits. The total amount of unrecognized tax benefits, including interest and penalties, that would affect the effective tax rate was $1.4 million as of August 31, 2012. The Company anticipates that total unrecognized tax benefits will decrease by approximately $.2 million during the 12 months from this reporting date due to various state tax filings associated with the resolution of the federal tax audit. The benefits of the Company’s net operating losses (“NOLs”), built-in losses and tax credits would be reduced or potentially eliminated if the Company experienced an “ownership change” under Internal Revenue Code Section 382 (“Section 382”). Based on the Company’s analysis performed as of August 31, 2012, the Company does not believe it has experienced an ownership change as defined by Section 382, and, therefore, the NOLs, built-in losses and tax credits the Company has generated should not be subject to a Section 382 limitation as of this reporting date.
