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 and six months ended June 30, 2018 and 2017 are as follows:


	Three Months Ended June 30,						Six Months Ended June 30,
	2018			2017			2018			2017
	(in thousands, except per share amounts)						(in thousands, except per share amounts)
Net loss– basic and diluted	$	(6,057	)	$	(2,096	)	$	(17,655	)	$	(3,427	)
Weighted-average shares outstanding – basic and diluted		20,327			14,456			18,474			14,426
Basic and diluted loss per common share	$	(0.30	)	$	(0.14	)	$	(0.96	)	$	(0.24	)

The computation of diluted loss per common share for the three and six months ended June 30, 2018 excludes 1,990,536 shares and 1,938,124 shares, respectively, related to options to purchase shares and other stock awards. The computation of diluted loss per common share for the three and six months ended June 30, 2017 excludes 1,990,982 shares and 1,997,072 shares, respectively, related to options to purchase shares and other stock awards. These shares were excluded due to their antidilutive effects.
