EARNINGS PER SHARE |
EARNINGS PER SHARE | 10. EARNINGS PER SHARE ​ Basic earnings per share is determined by dividing net income by the weighted average common shares outstanding during the period. The calculation of diluted earnings per share includes the dilutive effect of unexercised non-qualified stock options and non-vested restricted stock units. The computation of weighted average common shares outstanding excluded a nominal amount of anti-dilutive non-qualified stock options for each period ended June 30, 2023 and 2022. ​ The computations for basic and diluted earnings per share for the three and six months ended June 30, 2023 and 2022 are as follows: ​
