Income Taxes [Abstract]
Income Tax Disclosure [Text Block]	INCOME TAXES Our effective income tax rates were 39.6% for the three months ended July 31, 2012 and 0% for the same period in the prior year. The effective tax rate for the three months ended July 31, 2012 is higher than the comparable prior year period primarily due to operating earnings generated in the first three months of fiscal year 2013 as opposed to the loss incurred in the first three months of fiscal year 2012. As of July 31, 2012, the federal tax returns for the fiscal years ended 2008 through 2012 are open to audit until the statute of limitations closes for the years in which the net operating losses are utilized. We would recognize interest and penalties accrued on unrecognized tax benefits as well as interest received from favorable tax settlements within income tax expense. As of July 31, 2012, we recorded no accrued interest or penalties related to uncertain tax positions. We expect no significant change in the amount of unrecognized tax benefit, accrued interest or penalties within the next twelve months.
