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):

	Twenty Six Weeks Ended				Thirteen Weeks Ended
	June 25, 2016		June 27, 2015		June 25, 2016		June 27, 2015
Average number of common shares outstanding		42,315		44,240		42,235		43,892
Incremental shares from assumed exercises of stock options		109		157		122		141
Average number of common shares and common share equivalents outstanding		42,424		44,397		42,357		44,033

For each of the twenty-six-week and thirteen-week periods ended June 25, 2016 and June 27, 2015, 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 or market condition for vesting had not been satisfied.
