10.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 six months ended June 30, 2020 and 2019 were as follows:



	For the three months				For the six months
	ended June 30,				ended June 30,
Amounts in thousands	2020		2019		2020		2019
Weighted average common shares, basic		29,576		29,440		29,541		29,440
Dilutive effect of stock options		—		—		—		674
Weighted average common shares, diluted		29,576		29,440		29,541		30,114
