Income Tax Disclosure [Abstract]
U.S. Tax Reform	U.S. TAX REFORM On December 22, 2017, the U.S. government enacted the Tax Cuts and Jobs Act (the "Tax Act"). The Tax Act significantly revises the future ongoing U.S. corporate income tax by, among other things, decreasing U.S. corporate income tax rate to 21.0% from 35.0%. As the Company has a September 30 fiscal year-end, the lower corporate income tax rate will be phased in, resulting in a blended U.S. statutory federal rate of approximately 24.5% for the Company's fiscal year ending September 30, 2018, and 21.0% for subsequent fiscal years. In addition, the reduction of the corporate tax rate required the Company to revalue its deferred tax assets and liabilities based on the lower federal tax rate of 21.0%. As a result of the new legislation, during the quarter ended December 31, 2017, the Company recorded a one-time income tax expense of $548,000 in conjunction with writing down its net deferred tax assets. The impact of using the 24.5% blended federal tax rate for the nine months ended June 30, 2018 versus a 35.0% rate reduced the provision for income taxes by approximately $1.62 million, which was partially offset by the $548,000 one-time net deferred tax asset write-down.
