Net Income Per Share

12 Months Ended

Dec. 31, 2015

Basic net income per share is computed by dividing net income for the period by the weighted-average number of shares outstanding during the period. Diluted net income per share is computed by dividing net income for the period by the weighted-average number of shares, less shares repurchased, plus, if dilutive, potential common stock outstanding during the period. Potential common stock includes the effect of outstanding dilutive stock options, restricted stock awards and restricted stock units computed using the treasury stock method. The anti-dilutive weighted-average dilutive shares related to stock award plans are excluded from the computation of the diluted net income per share because their effect would have been anti-dilutive.

The calculation of basic and diluted net income per share is as follows:
