Earnings Per Share [Text Block] | Note 5. Loss Per Common Share We calculate basic loss per common share on the basis of the weighted average number of shares of common stock outstanding during the period. Diluted income per share is calculated using the weighted average number of shares of common stock outstanding during the period plus the effect of potential dilutive common shares during the period using the treasury stock and if-converted methods. Potential dilutive shares of common stock include outstanding unvested restricted stock awards, deferred restricted stock units, warrants and convertible preferred stock for periods in which we have reported net income. For periods in which we report net losses, potential dilutive shares of common stock are excluded, as their conversion and exercise would be anti-dilutive. The following table represents net loss per common share – basic and diluted (in thousands, except income (loss) per share):

For the three and nine months ended September 30, 2023 and 2022, all outstanding unvested restricted stock units, deferred restricted stock units, warrants and convertible preferred stock were excluded from the computation of diluted loss per share, as our reported net loss would cause their conversion and exercise to have an anti-dilutive effect on the calculation of diluted loss per share.
