The following table sets forth the computation of basic and diluted (loss) income per common share (in thousands, except per share data):


Basic (loss) income per common share	2018		2017		2016
Net (loss) income	$	(2,840)	$	3,704	$	10,778
Net loss (income) allocated to participating securities		27		(63)		(208)
Net (loss) income allocated to common shareholders	$	(2,813)	$	3,641	$	10,570

Basic weighted-average common shares outstanding		36,412		33,008		31,855
Basic (loss) income per common share	$	(0.08)	$	0.11	$	0.33

Diluted (loss) income per common share	2018		2017		2016
Net (loss) income	$	(2,840)	$	3,704	$	10,778
Net loss (income) allocated to participating securities		27		(61)		(202)
Net (loss) income allocated to common shareholders	$	(2,813)	$	3,643	$	10,576

Basic weighted-average common shares outstanding		36,412		33,008		31,855
Effect of dilutive options and awardsa		-		1,155		967
Diluted weighted-average common shares outstanding		36,412		34,163		32,822
Diluted (loss) income per common share	$	(0.08)	$	0.11	$	0.32

aWe excluded stock options from the calculation of diluted weighted-average common shares outstanding if the per share value, including the sum of (i) the exercise price of the options and (ii) the amount of the compensation cost attributed to future services and not yet recognized, was greater than the average market price of the shares, because the inclusion of these stock options would be antidilutive to (loss) income per common share. For the year ended December 31, 2018 all stock options and awards were excluded from the calculation of weighted-average common shares outstanding as these would be antidilutive to the net loss. For the years ended December 31, 2017 and 2016 stock options to purchase 227,000 and 1,000 shares, respectively, were excluded from the calculation of diluted weighted-average common shares outstanding.
