Earnings Per Share [Abstract]  
Earnings Per Share Earnings Per Share
The calculation of basic earnings per share is based on the weighted average number of common shares considered outstanding during the periods. The calculation of diluted earnings per share reflects the effect of all potentially dilutive securities (principally outstanding stock options and restricted stock grants). The number of weighted average shares used in the calculation of basic earnings per share and diluted earnings per share was as follows:
Three Months Ended September 30,Nine Months Ended September 30,

(In thousands)
Weighted average shares:
Basic shares230,733 231,342 230,740 231,292 
Equity-based compensation plans937 882 821 896 
Diluted shares231,670 232,224 231,561 232,188 
The calculation of diluted earnings per share for the three and nine months ended September 30, 2024 excluded an immaterial number of stock options because the exercise prices of these stock options exceeded the average market price of the Company’s common shares, and the effect of their inclusion would have been antidilutive. There were no antidilutive shares for the three and nine months ended September 30, 2025.
