2. EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding during the reporting period. Diluted earnings per share is computed similar to basic earnings per share except that it reflects the potential dilution that could occur if dilutive securities or other obligations to issue common stock were exercised or converted into common stock.

The computations for basic and diluted earnings (loss) per share for the years ended December 31, 2018, 2017 and 2016 are as follows:

(shares in thousands)
		2018			2017			2016
Income (loss) from continuing operations		11,016			(15,368	)		542
Loss on discontinued operations, net of income taxes		(17,309	)		(15,892	)		(8,719	)
Net loss	$	(6,293	)	$	(31,260	)	$	(8,177	)

Weighted-average common shares outstanding — basic		62,236			61,365			60,744
Effect of stock options and restricted stock units		1,371			—			623

Weighted-average common shares outstanding — diluted		63,607			61,365			61,367

Earnings (loss) per share from continuing operations — basic	$	0.18		$	(0.25	)	$	0.01
Earnings (loss) per share from continuing operations — diluted	$	0.17		$	(0.25	)	$	0.01
