Net Income Per Share
3. Net Income Per Share

Basic earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted earnings per share includes the weighted average number of common shares outstanding and the number of equivalent shares which would be issued related to the stock options, unvested restricted stock, and warrants using the treasury method, unless such additional equivalent shares are anti-dilutive.
