Basic earnings per common share is calculated by dividing net income available to common shareholders by the weighted average number of shares of common stock outstanding net of unvested shares of restricted stock.

Diluted earnings per common share is calculated by dividing net income available to common shareholders by the weighted average number of shares of common stock outstanding, adjusted for the dilutive effect of potential common shares issuable for stock options and restricted shares, as calculated using the treasury stock method. Adjustments to the weighted average number of shares of common stock outstanding are made only when such adjustments dilute earnings per common share.
