NOTE 17 – WARRANTS
The following table shows warrant activity for the years ended December 31, 2020 and 2019.
The fair value of the warrants are calculated using the Black-Scholes pricing model based on the estimated market value of the underlying stock at the valuation measurement date, the remaining contractual term of the warrants, risk-free interest rate, and expected volatility of the underlying Common Stock. There is a moderate degree of subjectivity involved when estimating the value of warrants with the Black-Scholes option pricing model as the assumptions used are moderately judgmental
The weighted-average life of the warrants is 2.2 years. The aggregate intrinsic value of the warrants outstanding and exercisable at December 31, 2020 is $0.
