Earnings per share |
Earnings per share | ​ ​ 4. Earnings per share ​ Earnings per share (“EPS”) is computed on a basic and diluted basis. Basic EPS is computed by dividing net income (less preferred stock dividends) available to common stockholders by the weighted average number of common shares outstanding during the period. The computation of diluted EPS assumes the issuance of common shares for all potential common shares outstanding during the reporting period and, if dilutive, the effect of stock options as computed under the treasury stock method. ​ The following summarizes information related to the computation of basic and diluted EPS: ​
