Income Per Share Income Per Share
Basic income per share for 2020, 2019 and 2018 was computed by dividing net income amounts by the weighted average number of common shares outstanding.

The weighted average number of shares used to calculate basic and diluted income per share were as follows:

Weighted average basic shares outstanding223,684 229,944 237,797 
Dilutive effect of stock options and restricted shares4,330 5,131 7,166 
Weighted average diluted shares outstanding228,014 235,075 244,963 
Diluted net income per share 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 2,064, 2,518 and 1,520 for 2020, 2019 and 2018, respectively, from our diluted net income per share calculation as they would have had anti-dilutive effects.
