Fair Value Disclosures [Text Block] | NOTE 11 - FAIR VALUE MEASUREMENTS We follow FASB ASC Topic No. 820, Fair Value Measurements and Disclosures (“ASC 820” ) in connection with financial assets and liabilities measured at fair value on a recurring basis subsequent to initial recognition. ASC 820 requires that assets and liabilities carried at fair value be classified and disclosed in one of the following categories: Level 1: Quoted market prices in active markets for identical assets and liabilities. Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data The hierarchy noted above requires us to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. The fair value of our recorded derivative liabilities is determined based on unobservable inputs that are not corroborated by market data, which is a (Level 3 ) classification. We record derivative liabilities on our balance sheet at fair value with changes in fair value recorded in our consolidated statements of operations. The fair value of our warrant derivative liabilities at June 30, 2017 and 2016 was $0 and $24,000, respectively. The table below sets forth a summary of changes in the fair value of our (Level 3 ) financial instruments for the year ended June 30, 2017:
Fair value measurements of warrants using significant unobservable inputs (Level 3 )
Balance at June 30, 2016 |  | $ | 24,000 |
Change in fair value of warrant liability |  |  | (14,000 | )
Warrant re-pricing modification charge (Note 9) |  |  | (10,000 | )
Balance at June 30, 2017 |  | $ | - |
The fair value of our warrant derivative liabilities and the change in the estimated fair value of derivative liabilities that we recorded during fiscal year 2017, related to warrants issued in connection with our private placement transactions (see Notes 8 and 9 ).
