Earnings per share

9 Months Ended

Sep. 30, 2014

Earnings Per Share. Basic earnings per share are computed based upon the weighted average number of common shares outstanding. Diluted earnings per share are computed based upon the weighted average number of common shares outstanding and dilutive common share equivalents (consisting of stock options, restricted stock units and employee stock purchase plan shares) outstanding during the periods using the treasury stock method.

The following is a reconciliation of the shares used to compute basic and diluted earnings per share (in thousands):

Number of shares used to compute diluted earnings per share	54,129	54,624	54,804	54,394
