Basic earnings per share is computed by dividing net income attributable to Henry Schein, Inc. by the weighted-average number of common shares outstanding for the period. Our diluted earnings per share is computed similarly to basic earnings per share, except that it reflects the effect of common shares issuable for presently unvested restricted stock and restricted stock units and upon exercise of stock options, using the treasury stock method in periods in which they have a dilutive effect.

A reconciliation of shares used in calculating earnings per basic and diluted share follows:

		Years Ended
		December 28,	December 29,	December 31,
		2013	2012	2011
Basic		85,926	87,499	90,120
Effect of dilutive securities:
	Stock options, restricted stock and restricted stock units	1,696	2,324	2,500
	Diluted	87,622	89,823	92,620

Weighted-average options to purchase 8 shares of common stock at an exercise price of $69.45 per share that were outstanding during the year ended December 31, 2011 were excluded from the computation of diluted earnings per share because the options' exercise price exceeded the average market price of our common stock during the year, thereby causing the effect of such options to be anti-dilutive.
