Warrant calculation description | The Company recalculated the value of warrants by applying a +/- 5% changes to the input variables in the Black-Scholes model that vary overtime, namely, the volatility and the risk-free rate. A 5.0% decrease or increase in volatility would not have materially changed the value of the warrants. A 5.0% decrease or increase in the risk-free rate would not have materially changed the value of the warrants; the value of the warrants is not strongly correlated with small changes in interest rates. | The Company recalculated the value of warrants by applying a +/- 5% changes to the input variables in the Black-Scholes model that vary overtime, namely, the volatility and the risk-free rate.
