9. DERIVATIVE INSTRUMENTS
The table below lists the Company’s derivative instruments as of July 31, 2012:
Warrant Liability/Embedded Derivative Liability
Warrant Liability
As of July 31, 2012, the Company had approximately 99.6 million of its total approximately 114.7 million total warrants classified as liabilities (liability warrants). Of these 99.6 million liability warrants, approximately 64.8 million warrants are outstanding and 34.8 million warrants are exchange warrants - nonexercisable. The Company utilizes the BSM Model to calculate the fair value of these warrants at issuance and at each subsequent reporting date. For those warrants with exercise price reset features (anti-dilution provisions), the Company computes multiple valuations, each quarter, using an adjusted BSM model, to account for the various possibilities that could occur due to changes in the inputs to the BSM model as a result of contractually-obligated changes (for example, changes in strike price to account for down-round provisions). The Company effectively weights each calculation based on the likelihood of occurrence to determine the value of the warrants at the reporting date. Approximately 47 million of our 99.6 million liability warrants are subject to anti-dilution provisions. A certain number of liability warrants contain a cash settlement provision in the event of a fundamental transaction (as defined in the common stock purchase warrant). Any changes in the fair value of the warrant liability (i.e. - the total fair value of all outstanding liability warrants at the balance sheet date) between reporting periods will be reported on the statement of operations.
At July 31, 2012, the fair value of the warrant liability was approximately $1,266,000. For the three months ended July 31, 2012 and July 31, 2011, the Company reported income of approximately $1.7 million and $6.9 million, respectively, due to changes in the fair value of the warrant liability.
