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,
	2026	2025	2026	2025
	(In thousands)
Weighted average shares:
Basic shares	229,159	230,733	229,049	230,740
Equity-based compensation plans	881	937	861	821
Diluted shares	230,040	231,670	229,910	231,561

There were no antidilutive shares for the three and nine months ended September 30, 2026 and 2025.
