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:

		Three Months Ended		Six Months Ended
		June 29,	June 30,	June 29,	June 30,
		2013	2012	2013	2012
Basic		86,370	88,490	86,483	88,161
Effect of dilutive securities:
	Stock options, restricted stock and restricted stock units	1,598	2,063	1,722	2,270
	Diluted	87,968	90,553	88,205	90,431
