Schedule of Weighted Average Number of Shares

Shares Used to Calculate Earnings per Share

	Years Ended December 31,
(In millions)	2023	2022	2021
Weighted-average shares
Basic(a)	46.2	47.3	49.5
Effect of dilutive stock awards	0.7	0.5	0.6

(a)We have deferred compensation plans for directors and certain of our employees.  Some amounts owed to participants are denominated in common stock units.  Each unit represents one share of common stock.  The number of shares used to calculate basic earnings per share includes the weighted-average common stock units credited to employees and directors under the deferred compensation plans.  Additionally, nonvested units containing only a service requirement are also included in the computation of basic weighted-average shares when the requisite service period has been completed.  Accordingly, basic and diluted shares include weighted-average units of 0.3 million in 2023, 0.3 million in 2022 and 0.3 million in 2021.

(b)Under the November 2021 ASR, based on our stock prices from November 1, 2021 to March 31, 2022, we would have received additional shares under the ASR if the settlement date had been March 31, 2022. Because the ASR settlement date did not occur until April 2022 and because any anticipated receipt of additional shares of our common stock would have be antidilutive, no amounts were included the computation of diluted EPS. The antidilutive impact from the first quarter of 2022 continued to have year-to-date antidilutive impact for the remainder of 2022.
