EARNINGS PER COMMON SHARE

Basic earnings per share is computed by dividing net income by the weighted-average number of common shares outstanding during the reporting period. Diluted earnings per share gives effect to all dilutive common shares outstanding during the reporting period. The dilutive shares we consider in our diluted earnings per share calculation relate to our outstanding stock options, restricted stock awards and restricted stock unit awards.

We determine the dilutive effect of our outstanding stock options using the "treasury stock" method. Under this method, we assume the exercise of all of the outstanding stock options whose exercise price is less than the weighted-average market value of our common stock during the reporting period. This method also assumes that the proceeds from the hypothetical stock option exercises are used to repurchase shares of our common stock at the weighted-average market value of the stock during the reporting period. The net of the assumed stock options exercised and assumed common shares repurchased represents the number of dilutive common shares, which we add to the denominator of the earnings per share calculation.
