Net Income Per Share
Net Income Per Share

Basic net income per share was computed by dividing net income amounts by the weighted average number of shares of common stock outstanding.

The weighted average number of shares used to calculate basic and diluted net income per share were as follows:
 
Three Months Ended
 
March 31,
2019
 
April 1,
2018
Common stock:
 
 
 
Weighted average basic shares outstanding
230,584

 
239,928

Dilutive effect of stock options and restricted shares
5,310

 
8,491

Weighted average diluted shares outstanding
235,894

 
248,419



Diluted net income per share for the three months ended March 31, 2019 and April 1, 2018 was computed by dividing net income by the weighted average number of basic shares outstanding plus the potential common share effect of dilutive stock options and restricted shares. We excluded potential common shares of 2,158 and 2,711 for the three months ended March 31, 2019 and April 1, 2018, respectively, from our diluted net income per share calculation as they would have had anti-dilutive effects.
