Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recognizes deferred income taxes under the asset and liability method of accounting for income taxes in accordance with the provisions of ASC No. 740, Accounting for Income Taxes. Deferred income taxes are recognized for differences between the financial statement and tax basis of assets and liabilities at enacted statutory tax rates in effect for the years in which the differences are expected to reverse. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. In assessing the realizability of deferred tax assets, the Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income or reversal of deferred tax liabilities during the periods in which those temporary differences become deductible. At October 31, 2016, the Company determined that it was more-likely-than-not to realize the majority of its deferred tax assets, and therefore released its valuation against those assets resulting in a benefit to income taxes of $17,962,000. The Company has left a partial valuation allowance against certain state deferred tax assets that the Company does not believe it is more-likely-than-not to realize. The year January 31, 2014 and subsequent years remain open for examination by the IRS. The fiscal year ended January 31, 2012 and subsequent years remain open for examination by state tax authorities. The Company is not currently under IRS or state examination. We do not believe that there are any positions for which it is reasonably possible that the total amount of unrecognized tax benefits will significantly increase or decrease within the next 12 months.
