Earnings Per Share

Note 3 — Earnings Per Share

Basic earnings per share is computed by dividing net income by the weighted average number of shares outstanding during each period presented, which excludes non-vested restricted stock units. Diluted earnings per share is computed by dividing net income by the weighted average number of shares outstanding plus the dilutive effect of stock equivalents outstanding during the applicable periods using the treasury stock method. Diluted earnings per share reflects the potential dilution that could occur if options to purchase stock were exercised into common stock. Stock options that were not included in the computation of diluted earnings per share because to do so would have been antidilutive were 1.6 million and 1.9 million shares for the 13-week periods ended July 28, 2012, and July 30, 2011, and 1.6 million and approximately 342,000 for the 26-week periods ended July 28, 2012, and July 30, 2011, respectively.
