|Note 13 - Warrants||
The Company utilized a Black-Scholes options pricing model to value the warrants sold and issued. This model requires the input of highly subjective assumptions such as the expected stock price volatility and the expected period until the warrants are exercised. When calculating the value of warrants issued, the Company uses a volatility factor of 100%, a risk free interest rate and the life of the warrant for the exercise period.
The following table summarizes information about common stock warrants outstanding at March 31, 2019:
