Earnings Per Share
10. Earnings per share

Basic net earnings per share ("EPS") is calculated using net earnings available to common stockholders divided by the weighted-average number of shares of common stock outstanding for the period. Diluted EPS is similar to basic EPS except that the weighted-average number of shares is increased to include the number of additional common shares that would have been outstanding if the potentially dilutive common shares had been issued.

Dilutive common stock options are included in the diluted EPS calculation using the treasury stock method. Common stock options and unvested restricted shares (units) that were not included in the diluted EPS computation because the price was greater than the average market price of the common shares for the three months ended July 2, 2011 and July 3, 2010 were 1,119 and 1,208, respectively. Common stock options and unvested restricted shares (units) that were not included in the diluted EPS computation because the price was greater than the average market price of the common shares for the six months ended July 2, 2011 and July 3, 2010 were 1,125 and 1,199, respectively.
