Earnings Per Share [Abstract] |
Earnings Per Share | EARNINGS PER SHARE Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding for the period, including vested restricted stock unit (“RSU”) awards. Diluted EPS is computed by dividing net income by the weighted average number of shares outstanding, noted above, adjusted for the dilutive effect of stock options and unvested RSU awards. The following table presents the calculation of basic and diluted EPS:
