BASIC AND DILUTED SHARES

Basic and diluted weighted-average shares outstanding for the

three

months ended

March 31, 2018

and

2017

were as follows:

	Three Months Ended
	March 31,
	2018		2017
Basic and diluted		19,058,202		18,962,823
Potentially dilutive		27,500		27,500

Basic net income (loss) per common share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding. Diluted net income (loss) per common share is computed similar to basic net income (loss) per common share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the dilutive potential common shares from share-based compensation arrangements had been issued.

Potentially dilutive shares arise from non-qualified stock options to purchase common stock. The treasury stock method is utilized to determine the number of potentially dilutive shares related to the outstanding non-qualified stock options.
