Earnings Per Share [Abstract]  
Earnings per share reconciliation
The following table presents the reconciliation (in millions) of our net income to net income allocated to our common stockholders and the weighted-average shares (in millions) that are used in calculating the basic and diluted earnings per share on our common stock. Weighted-average common shares outstanding assuming dilution reflects the potential dilution, determined using the treasury stock method that could occur if outstanding stock options were exercised and non-participating stock awards vested.
