Earnings Per Share [Abstract]

Earnings Per Share

NOTE 5 — EARNINGS PER SHARE

We compute basic earnings per share using the weighted average number of common shares outstanding. We compute diluted earnings per share using the weighted average number of common shares outstanding plus the dilutive effect of outstanding stock options, SARs, RSUs and PSUs, computed using the treasury stock method. During 2021, 2020 and 2019, we repurchased 37.812 million shares, 3.287 million shares and 7.949 million shares, respectively, of our common stock. The following table sets forth the computations of basic and diluted earnings per share for the years ended December 31, 2021, 2020 and 2019 (dollars and shares in millions, except per share amounts):
