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, 2017 and 2016 were as follows:



	For the three months				For the six months
	ended June 30,				ended June 30,
Amounts in thousands	2017		2016		2017		2016

Weighted average common shares, diluted		24,962		24,548		24,911		24,616
