Earnings Per Share [Text Block] | Note 5. Income (Loss) Per Common Share We calculate basic income (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, performance-based share awards, 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 income (loss) per common share – basic and diluted (in thousands, except income (loss) per share):

Diluted weighted average common shares |  |  | 540,527 |  |  |  | 523,215 |
Basic income (loss) per common share |  | $ | 0.04 |  |  | $ | (0.03 | )
Diluted income (loss) per common share |  | $ | 0.03 |  |  | $ | (0.03 | )
Diluted income (loss) per share for the three months ended March 31, 2021 and 2020 excludes the potential effects of outstanding shares of our convertible preferred stock, as their conversion would have no effect on the calculation of dilutive shares. For the three months ended March 31, 2021, the calculation of diluted income per common share included (i) 2,863,038 restricted stock units that were unvested during the period, (ii) 1,536,615 warrants to purchase one share of common stock and (iii) 2,026,440 deferred shares that were dilutive. For the three months ended March 31, 2020, all outstanding restricted stock units, warrants and deferred shares were excluded from the computation of diluted loss per share, as our reported net losses for those periods would cause their conversion and exercise to have no effect on the calculation of loss per share.
