Earnings Per Share [Abstract]  
Earnings Per Share Earnings Per Share
Earnings per share is computed using the treasury stock method. Stock options and stock appreciation rights to purchase 10 million and 6 million shares of common stock were outstanding, but were excluded from the calculation of diluted earnings per share for the three months ended March 31, 2025 and 2024, respectively, because their exercise prices were greater than the average market price of the common shares and, therefore, the effect would be antidilutive.

The following is a reconciliation of basic and diluted earnings per share for the three months ended March 31, 2025 and 2024:
