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 9 million and 10 million shares of common stock were outstanding, but were excluded from the calculation of diluted earnings per share for the three and six months ended June 30, 2025, respectively, because their exercise prices were greater than the average market price of the common shares and, therefore, the effect would be antidilutive. For the same reason, stock options and stock appreciation rights to purchase 7 million shares of common stock were outstanding, but were excluded from the calculation of diluted earnings per share for each of the three and six-month periods ended June 30, 2024.

The following is a reconciliation of basic and diluted earnings per share for the three and six months ended June 30, 2025 and 2024:
