Conversion price description             The Company has been converting the convertible notes in its shares of common stock at a fifteen percent (15%) discount to the lowest volume weighted average price (“VWAP”) whereas the terms of the agreement state that such discount to the original conversion price of $2.49 should have been initiated on or after the maturity date of the convertible notes or September 4, 2019. The accounting standards require the recognition through earnings of an inducement charge equal to the fair value of the consideration delivered in excess of the consideration issuable under the original conversion terms. This resulted in a non-cash charge of $3.8 million for the year ended August 31, 2019.
