Fair Value Disclosures [Text Block]	4 . Fair Value Measurements The Company records its financial assets and liabilities at fair value in accordance with the framework for measuring fair value. The framework establishes a fair value hierarchy that distinguishes between assumptions based on market data (observable inputs) and market participant’s assumptions (unobservable inputs). Non-financial assets, such as goodwill and long-lived assets, are accounted for at fair value on a non-recurring basis. These items are tested for impairment on the occurrence of a triggering event or in the case of goodwill, at least on an annual basis. As of September 30, 2017 and 2016, the Company did not have any financial assets or liabilities that were subject to fair value measurements. The carrying amounts of the Company’s financial assets and liabilities, including cash and cash equivalents, restricted cash, accounts receivable, accounts payable and other accrued expenses, approximate fair value because of the short maturity of those assets and liabilities.
