Income Taxes [Abstract]
Income Taxes	Income Taxes The Company uses the asset and liability method for financial reporting of income taxes. Deferred tax assets and liabilities are determined based on temporary differences between financial reporting and the tax basis of assets and liabilities, and are measured by applying enacted rates and laws to taxable years in which such differences are expected to be recovered or settled. Any changes in tax rates or laws are recognized in the period when such changes are enacted. Valuation allowances have been established when necessary to reduce deferred tax assets to the amount expected to be realized. The Company records a valuation allowance to reduce its deferred tax assets when uncertainty exists regarding the realizability of the deferred tax assets. The provisions for income taxes were approximately $200,000 and $1.9 million for the three and nine months ended January 31, 2014, respectively. The effective rate was 34.73% for 2014, compared to a minimal effective rate for 2013. The increase in the effective rate for 2014 was due to the reversal of a portion of the valuation allowance and recording of a deferred tax asset at April 30, 2013. This deferred tax asset was fully recognized in the nine months ended January 31, 2014.
