EARNINGS PER SHARE

NOTE 6 — 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 and RSUs, computed using the treasury stock method. During March 2011, we completed the initial public offering of 87,719,300 shares of our common stock, and during September 2011, we repurchased 80,771,143 shares of our common stock. The following table sets forth the computations of basic and diluted earnings per share for the years ended December 31, 2012, 2011 and 2010 (dollars in millions, except per share amounts, and shares in thousands):
