Simultaneously with any reduction to the exercise price, the number of shares of common stock that may be purchased upon exercise of each of these warrants shall be increased based on a pre-defined formula. In addition, prior to the effectiveness of certain resale registration statements or if any such registration statements are no longer effective, the holder of the Company’s warrants, at their option, may exercise all or any part of the warrants in a “cashless” or “net-issue” exercise. The Company’s derivative instruments have been measured at fair value at inception and at each reporting period using a simulation model.

On analysis of comparable companies and other information the Company has determined that the use of 2.25 The warrant derivative liability is classified within Level 3 of the fair value hierarchy because on initial recognition and again at each reporting period, it was valued using these significant inputs and assumptions that are unobservable in the market. Changes in the values assumed and used in the simulation model can materially affect the estimate of fair value. Generally, an increase in the market price of the Company’s shares of common stock, an increase in the volatility of the Company’s shares of common stock and an increase in the expected life would result in a directionally similar change in the estimated fair value of the warrant derivative liability. An increase in the risk free rate would result in a decrease in the fair value of the warrant derivative liability. The expected life is based on the remaining contractual term of the warrants. The risk free rate was based on U.S. treasury-note yields with terms commensurate with the remaining term of the warrants. Expected volatility over the expected term of the warrants is estimated based on consideration of historical volatility and other information. In addition to the assumptions above, the Company also took into consideration the probability of the Company’s participation in another round of financing, the type of such financing and the range of the stock price for the financing at that time. At each increment of the simulation, the daily volume weighted-average price was calculated. If this amount was 200 |
