Earnings Per Share

(3) Earnings Per Share

Earnings per common share are based on the weighted average number of shares outstanding, including outstanding non-vested restricted stock. Diluted earnings per share are based on the weighted average number of common shares outstanding plus the incremental shares that would have been outstanding upon the assumed exercise of all dilutive stock options.

The following table provides a reconciliation of the average number of common shares outstanding used to calculate earnings per common share to the average number of common shares and common share equivalents outstanding used to calculate diluted earnings per share (in thousands):

	Thirteen Weeks Ended
	March 30, 2013		March 31, 2012
Average number of common shares outstanding		46,507		46,800
Incremental shares from assumed exercises of stock options		215		261
Average number of common shares and common share equivalents outstanding		46,722		47,061

For the thirteen-week period ended March 30, 2013, there were 154,500 options outstanding to purchase shares of common stock excluded from the calculation of diluted earnings per share because they were antidilutive. For the thirteen-week period ended March 31, 2012, no options outstanding to purchase shares of common stock were excluded from the calculation of diluted earnings per share because they were antidilutive. For the thirteen-week periods ended March 30, 2013 and March 31, 2012, outstanding RSUs were excluded from the calculation of diluted earnings per share because the performance metric requirements for vesting had not been satisfied.
