Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes Income taxes for interim periods have been computed using an estimated annual effective tax rate. This rate is revised, if necessary, at the end of each successive interim period to reflect the current estimate of the annual effective tax rate. At September 30, 2011, the Company estimates that its effective annual income tax rate for 2011 will approximate 36.9%.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
