Earnings Per Share [Text Block] | NOTE 9 - EARNINGS PER SHARE Basic and diluted net income (loss) per common share is determined by dividing net income (loss) by the weighted average common shares outstanding during the period. For the periods where there is a net loss, stock options, warrants and Restricted Stock Units have been excluded from the calculation of diluted net loss per common share because their effect would be anti-dilutive. Consequently, the weighted average common shares used to calculate both basic and diluted net loss per common share would be the same. For the year ended December 31, 2020, the Company had 128,299 stock grants outstanding to issue common stock (“RSUs”). Further, the Company had 515,000 prefunded warrants outstanding to issue common stock. For the year ended December 31, 2019, the Company had 125,293 RSUs outstanding. Further, the Company had 25,000 options outstanding to purchase common stock at $2.96 per share. The following data shows the amounts used in computing earnings per share, the effect on income and the weighted average number of shares of potential dilutive common stock for the years ended December 31, 2020 and 2019:
