Earnings Per Share [Abstract] |
Earnings Per Share | Earnings per Share We compute basic earnings per share by dividing net income available to our common shareholders by the weighted-average number of shares of our common stock outstanding. We weight shares issued or reacquired for the portion of the period that they were outstanding. Our diluted earnings per share reflect the impacts of our potentially dilutive securities, which include our equity compensation awards. The following table shows the computation of our basic and diluted net income per common share (in millions, except per share amounts):
