EARNINGS PER SHARE

NOTE 3 — 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, stock appreciation rights and restricted share units, computed using the treasury stock method. During September 2011, we repurchased 80.8 million shares of our common stock.

The following table sets forth the computation of basic and diluted earnings per share for the quarters and nine months ended September 30, 2012 and 2011 (dollars in millions, except per share amounts, and shares in thousands):
