Earnings Per Share [Abstract]  
Earnings per Share Earnings per Share
We calculate basic earnings per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share further includes the dilutive effect of stock-based compensation awards. We calculate that dilutive effect using the “treasury stock method” (as defined by GAAP).
The following table presents information concerning basic and diluted earnings per share: 
202220232024
Net income available to common stockholders$838 $783 $1,024 
Share data (in thousands):
Basic average common shares outstanding478,879 479,155 476,394 
Dilutive effect of stock-based awards1,686 1,310 826 
Diluted average common shares outstanding480,565 480,465 477,220 
Basic earnings per share$1.75 $1.63 $2.15 
Diluted earnings per share$1.74 $1.63 $2.14 
We excluded common stock-based awards for approximately 691,000 shares, 1,107,000 shares, and 1,689,000 shares from the calculation of diluted earnings per share for 2022, 2023, and 2024, respectively, because they were not dilutive for those periods under the treasury stock method.
