Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On December 22, 2017, the U.S. Government enacted significant tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). For businesses, the Tax Act reduces the corporate federal tax rate from a maximum of 35% to a flat 21% rate. The corporate tax rate reduction was effective January 1, 2018. Because the Company has a fiscal year end of September 30, the reduced corporate tax rate will result in the application of a blended federal statutory tax rate of 24.53% for its fiscal year 2018 and then a flat 21% thereafter. Under generally accepted accounting principles, the Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to 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. At September 30, 2017, the Company’s deferred tax assets and liabilities were determined based on the then-current enacted federal tax rate of 35%. As a result of the reduction in the corporate income tax rate under the Tax Act, the Company revalued its deferred tax assets and liabilities at December 31, 2017. Deferred tax assets and liabilities expected to be realized in fiscal year 2018 were re-measured using the aforementioned blended rate. All remaining deferred tax assets and liabilities were re-measured using the new statutory federal rate of 21%. These re-measurements resulted in a discrete tax benefit estimate of $3,743,000 that was recognized during the three months ended December 31, 2017. The Company’s revaluation of its deferred tax assets and liabilities is subject to further clarification of the Tax Act and refinements of its estimates.

On December 22, 2017, the U.S. Government enacted significant tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). For businesses, the Tax Act reduces the corporate federal tax rate from a maximum of 35% to a flat 21% rate. The corporate tax rate reduction was effective January 1, 2018. Because the Company has a fiscal year end of September 30, the reduced corporate tax rate will result in the application of a blended federal statutory tax rate of 24.53% for its fiscal year 2018 and then a flat 21% thereafter.

Under generally accepted accounting principles, the Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to 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.

At September 30, 2017, the Company’s deferred tax assets and liabilities were determined based on the then-current enacted federal tax rate of 35%. As a result of the reduction in the corporate income tax rate under the Tax Act, the Company revalued its deferred tax assets and liabilities at December 31, 2017. Deferred tax assets and liabilities expected to be realized in fiscal year 2018 were re-measured using the aforementioned blended rate.
