NET INCOME PER SHARE

Basic net income per share is computed using the weighted average number of common shares outstanding for the period, excluding unvested restricted stock units and performance awards. Diluted net income per share is based upon the weighted average common shares outstanding for the period plus dilutive potential common shares, including unvested restricted stock units, performance share awards, and stock options using the treasury stock method.

The following table sets forth the computation of basic and diluted net income per share for fiscal 2017, 2016 and 2015 (in thousands, except per share data):
