NOTE I—LOSS PER COMMON SHARE

Basic loss per common share has been computed by dividing net loss by the weighted-average number of shares of the Company’s common stock outstanding during the relevant period. Diluted loss per common share adjusts net loss and basic loss per common share for the effect of all potentially dilutive shares of the Company’s common stock. The calculations of basic and diluted loss per common share for the three month periods ended March 31, 2018 and 2017 are as follows:


	Three Months Ended March 31,
	2018			2017
	(in thousands, except per share amounts)
Net loss– basic and diluted	$	(11,598	)	$	(1,331	)
Weighted-average shares outstanding – basic and diluted		16,601			14,396
Basic and diluted loss per common share	$	(0.70	)	$	(0.09	)

The computation of diluted loss per common share for the three months ended March 31, 2018 and 2017 excludes 1,885,711 shares and 2,003,162 shares, respectively, related to options to purchase shares and other stock awards. These shares were excluded due to their antidilutive effects.
