Share-based Payment Arrangement [Text Block] | NOTE 13. WARRANTS AND OPTIONS Options At June 30, 2021 and December 31, 2020, we had fully vested options outstanding to purchase 200,648, respectively, of shares of common stock at exercise prices ranging from $6.29 to $134.00 per share. Due to the high level of volatility in the stock price of our common stock, our management determined the grant date fair value of the options using the then quoted stock price at the grant date. Warrants At June 30, 2021 and December 31, 2020, we had warrants outstanding to purchase 404,676 shares of common stock. At June 30, 2021 the warrants had a weighted average exercise price of $11.12 per share purchased and a weighted average remaining contractual term of 1.50 years. At December 31, 2020, the warrants had a weighted average exercise price of $6.18 per share purchased and a weighted average remaining contractual term of 3.00 years. Non-Incentive Plan Options At June 30, 2021 and December 31, 2020, we had 46,643 non-incentive options outstanding with a weighted-average exercise price of $21.46. These non-incentive options contract terms expired as of June 30, 2021. These options were out of the money at December 31, 2020 and had no intrinsic value.
