Warrants | In January 2018, the Company offered warrant holders the opportunity to exercise their warrants at a reduced strike price of $2.50, and if so elected, would also have the opportunity to reprice other warrants that they continue to hold unexercised to $3.25. The offer, which was effective January 12, 2018, was for the repricing only and did not modify the life of the warrants. Warrant holders of approximately 503,000 shares exercised their warrants and also had other warrants modified on approximately 197,000 shares, which resulted in a charge of approximately $429,000 in the nine months ended September 30, 2018. Cash proceeds on the exercise of these warrants as well as the stock subscriptions as of December 31, 2017 of $1,071,070 amounted to approximately $2,300,000 in January 2018.

The weighted average fair value of warrants granted to non-employees during the nine months ended September 30, 2018 and 2017 was $1.70 and $2.40, respectively. The fair value was estimated on the grant dates using the Black-Scholes option-pricing model with the following weighted-average assumptions: September 30, September 30, 2018 2017 Expected life (in years) 5 Volatility 84 % 87 % Risk-free interest rate 2.70 % 1.82% - 1.92 % Dividend yield - % - % The expected term of the warrants is based on the actual term of the warrants. Volatility is based on the historical volatility of several public entities that are similar to the Company. The Company bases volatility this way because it does not have sufficient historical transactions in its own shares on which to solely base expected volatility. The risk-free interest rate is based on the U.S. Treasury rates at the date of grant with maturity dates approximately equal to the expected term at the grant date. The Company has not historically declared any dividends and does not expect to in the future. |
