	13 Weeks Ended April 29, 2011					13 Weeks Ended April 30, 2010
	Net Income		Shares	Per Share Amount		Net Income		Shares	Per Share Amount
Basic earnings per share	$	156,969	341,522	$	0.46	$	135,996	340,819	$	0.40
Effect of dilutive share-based awards			3,871					3,578
Diluted earnings per share	$	156,969	345,393	$	0.45	$	135,996	344,397	$	0.39

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

Options to purchase shares of common stock 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 options would be antidilutive, were 0.4 million and 0.3 million in the 2011 and 2010 periods, respectively.
