	13 Weeks Ended August 3, 2018					13 Weeks Ended August 4, 2017
			Weighted					Weighted

	26 Weeks Ended August 3, 2018					26 Weeks Ended August 4, 2017
			Weighted					Weighted
	Net		Average	Per Share		Net		Average	Per Share
	Income		Shares	Amount		Income		Shares	Amount
Basic earnings per share	$	772,089	267,362	$	2.89	$	574,272	274,191	$	2.09

Diluted earnings per share	$	772,089	268,180	$	2.88	$	574,272	274,674	$	2.09

Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is determined based on the dilutive effect of share-based awards using the treasury stock method.

Share-based awards that were outstanding at the end of the respective periods, but were not included in the computation of diluted earnings per share because the effect of exercising such awards would be antidilutive, were 0.9 million and 2.6 million in the 2018 and 2017 13-week periods, and 0.9 million and 2.6 million in the 2018 and 2017 26-week periods, respectively.
