Earnings Per Share [Text Block] | Note 17. Loss Per Share Basic loss per share excludes dilution and is computed by dividing the loss attributable to common shareholders by the weighted-average number of shares outstanding for the period. Diluted (loss) income per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock, except for periods when the Company reports a net loss, because the inclusion of such items would be antidilutive. The antidilutive effect of 841,724 and 692,312 shares from stock options and 75,371 and 39,847 shares from warrants were excluded from diluted shares for the years ended December 31, 2022 and 2021, respectively.
