Unvested shares of restricted stock are excluded from basic shares outstanding. Diluted earnings per share reflects the potential dilution that could occur if outstanding stock options at the presented dates are exercised and shares of restricted stock have vested, using the treasury stock method. The treasury stock method assumes proceeds from the exercise price of stock options, the unamortized compensation expense and assumed tax benefits of options and restricted stock are available to acquire shares at an average market price throughout the year, and therefore, reduce the dilutive effect. </div> </div> <!--DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" --> <!-- Begin Block Tagged false false false us-types:textBlockItemType textblock Discloses the methodology and assumptions used to compute basic and diluted earnings (loss) per share for each class of common stock and participating security.
