Earnings Per Common Share |
Earnings Per Common Share | Note 12: Earnings Per Common Share ​ Basic earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding, which include DSUs that are vested but not delivered. Diluted earnings per common share is computed using the treasury stock method and reflects the potential dilution that could occur if the Company’s outstanding stock options and warrants were exercised, stock units were vested, and ESPP shares were issued. ​ Earnings per common share have been computed as follows (dollars in thousands, except per share amounts): ​
