Earnings Per Common Share [Abstract]

Earnings Per Common Share

3. Earnings Per Common Share

Basic earnings per share are computed by dividing net earnings by the daily weighted average number of common shares outstanding during the applicable periods. Diluted earnings per share include the potentially dilutive effect of common shares issued in connection with outstanding stock-based compensation options and grants, using the treasury stock method. Under the treasury stock method, shares associated with certain stock options have been excluded from the diluted weighted average shares outstanding calculation because the exercise of those options would lead to a net reduction in common shares outstanding. As a result, stock options to acquire less than 0.1 million and 0.3 million weighted average common shares have been excluded from diluted weighted average shares outstanding for the three-fiscal month periods ended March 31, 2012 and April 2, 2011, respectively. Stock options to acquire 0.4 million and 0.5 million weighted average common shares have been excluded from diluted weighted average shares outstanding for the six-month fiscal periods ended March 31, 2012 and April 2, 2011, respectively. The potentially dilutive effect of common shares issued in connection with outstanding stock options is determined based on net income. A reconciliation of these amounts is as follows:
