The fair value of the stock warrant was determined on the date of the warrant purchase agreement using a Monte Carlo simulation method that reflected the impact of the key features of the warrant using different simulations and probability weighting. Expected Term. The expected term was determined based on the maturity determined period that both parties expect the warrant to be outstanding. Expected Volatility. The expected volatility was based on implied volatility. Risk-free Interest Rate. The risk-free interest rate was based on zero-coupon U.S. Treasury yields in effect at the date of the agreement with the same maturity as the expected warrant term. Expected Dividend Yield.
