Earnings Per Share | Earnings Per Share Basic earnings per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period presented. Diluted earnings per share is computed by including the net increase in shares as if dilutive outstanding restricted stock awards were vested, using the treasury stock method. Basic and diluted earnings per share has been computed based on the following:

Diluted earnings per share | $ | 1.50 |  |  | 1.59 |  |  | 1.54 |
