(Dollar amounts in thousands, except per share data)	2013			2012			2013			2012
Net (loss) income	$	(64,935	)	$	(2,033	)	$	(59,463	)	$	1,501
Weighted average common shares outstanding		78,928,780			72,672,852			75,849,551			72,659,463
Weighted average potential dilutive common shares (1)(2)		—			—			—			4,243,747
Weighted average common shares outstanding—assuming dilution		78,928,780			72,672,852			75,849,551			76,903,210
Net (loss) income per common share—basic	$	(0.82	)	$	(0.03	)	$	(0.78	)	$	0.02
Net (loss) income per common share—diluted	$	(0.82	)	$	(0.03	)	$	(0.78	)	$	0.02

(1) Potential common shares consist of common stock issuable under the assumed exercise of stock options and restricted stock awards using the treasury stock method.

(2) For the three months ended June 30, 2013 and 2012, 3,818,726 and 3,950,989, respectively, potential common shares consisting of common stock under the assumed exercise of stock options and restricted stock awards using the treasury stock method were not included in the computation of the diluted net (loss) income per share since their inclusion would have an antidilutive effect. For the six months ended June 30, 2013, 4,227,114 potential common shares consisting of common stock under the assumed exercise of stock options and restricted stock awards using the treasury stock method were not included in the computation of the diluted net (loss) income per share since their inclusion would have an antidilutive effect.
