3. BASIC AND DILUTED SHARES

Basic and diluted weighted-average shares outstanding for the three months ended March 31, 2016 and 2015 were as follows:

	Three Months Ended
	March 31 ,
	2016		2015
Basic and diluted		18,903,466		18,220,775
Potentially dilutive		22,604		47,500

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding. Diluted net income (loss) per share is computed similar to basic net income (loss) per 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 and non-vested restricted stock. The treasury stock method is applied to determine the number of potentially dilutive shares for non-vested restricted stock and stock options assuming that the shares of non-vested restricted stock are issued for an amount based on the grant date market price of the shares and that the outstanding stock options are exercised. These amounts were excluded because the effect would be insignificant.
