Diluted$.97 $.82 $.89 

Basic net income per share for 2023, 2022 and 2021 was computed by dividing net income amounts by the weighted average number of shares of common stock outstanding. 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 5,377, 4,443 and 2,404 for 2023, 2022 and 2021, respectively, from our diluted net income per share calculation as they would have had anti-dilutive effects.
