Income Taxes [Abstract]
Income Taxes	10. Income Taxes The liability method is used in accounting for income taxes as required by U.S. GAAP. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period that includes the enactment date. In assessing the value of deferred tax assets, the Company considers whether it was more likely than not that some or all of the deferred tax assets would not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. Based upon these considerations, the Company provides a valuation allowance to reduce the carrying value of certain of its deferred tax assets to their net expected realizable value, if applicable. The Company has concluded that no valuation allowance is required for deferred tax assets at September 30, 2011 and June 30, 2011, respectively. Effective income tax rates of 37.8% and 37.3% for the three months ended September 30, 2011 and September 30, 2010, respectively, varied from the statutory federal income tax rate of 35% primarily as a result of the effect of state income taxes.

The liability method is used in accounting for income taxes as required by U.S. GAAP. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period that includes the enactment date.
