Earnings Per Share

Note 9Earnings Per Share

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:
