EARNINGS PER SHARE

9 Months Ended

Sep. 30, 2021

Diluted earnings per share was computed based on the weighted-average number of shares outstanding plus all potentially dilutive common shares. A reconciliation of basic to diluted shares used in the earnings per share calculation is as follows:


	Three Months Ended		Nine Months Ended
	September 30,		September 30,
(In thousands)	2021	2020	2021	2020
Basic weighted-average shares outstanding	40,769	41,545	40,865	41,926
Dilutive effect of stock options and deferred stock compensation	181	252	175	264
Diluted weighted-average shares outstanding	40,950	41,797	41,040	42,190

There were no anti-dilutive equity-based awards for the three months ended September 30, 2021. For the nine months ended September 30, 2021, approximately 41,000 shares issuable under equity-based awards were excluded from the calculation of diluted earnings per share as they were anti-dilutive based on the average stock price during the period. There were no anti-dilutive equity-based awards for three and nine months ended September 30, 2020.
