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 28, 2015		March 29, 2014
Average number of common shares outstanding		44,588		45,407
Incremental shares from assumed exercises of stock options		172		189
Average number of common shares and common share equivalents outstanding		44,760		45,596

For the thirteen-week periods ended March 28, 2015 and March 29, 2014, no options outstanding to purchase shares of common stock were antidilutive. Outstanding RSUs were excluded from the calculation of diluted earnings per share for all periods because the performance metric requirements for vesting had not been satisfied.
