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 outstanding unvested restricted stock awards and vested restricted stock unit 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. The following table presents the calculation of basic and diluted EPS:
