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

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.
