9.EARNINGS PER SHARE

The calculation of basic earnings per share considers only weighted average outstanding common shares in the computation. The calculation of diluted earnings per share gives effect to all potentially dilutive stock options. The calculation of diluted earnings per share is based upon the weighted average number of common shares outstanding during the period, plus, if dilutive, the assumed exercise of stock options using the treasury stock method. Weighted average shares outstanding for the three and nine months ended September 30, 2022 and 2021 were as follows:



	For the three months				For the nine months
	ended September 30,				ended September 30,
Amounts in thousands	2022		2021		2022		2021

Weighted average common shares, diluted		31,404		31,242		31,523		31,059
