Note 2 — Income (Loss) Per Common Share

Basic income (loss) per common share is calculated by dividing net income (loss) available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted income (loss) per common share is calculated by dividing net income available to common stockholders by using the weighted average number of common shares and common share equivalents outstanding during the period. The computations of basic and diluted income (loss) per common share are as follows:

	For the year ended December 31,
	2015			2014			2013
	(in thousands, except per share amounts)
Net income (loss)	$	(31,978	)	$	(66,940	)	$	(42,263	)
Net income (loss) per common share:
Basic	$	(0.80	)	$	(1.70	)	$	(1.09	)
Diluted	$	(0.80	)	$	(1.70	)	$	(1.09	)

Basic weighted average shares outstanding	39,742			39,350			38,807
Effect of potentially dilutive share-based awards	—			—			—

Diluted weighted average shares outstanding	39,742			39,350			38,807

For the years ended December 31, 2015, 2014, and 2013, 1.2 million, 0.7 million and 0.6 million common equivalent shares, respectively, were excluded from the computation of net loss per share since the Company incurred a net loss. In addition, for the years ended December 31, 2015, 2014, and 2013, respectively, 2.1 million, 1.6 million and 1.3 million potentially dilutive securities underlying restricted stock awards, restricted stock units, and options to purchase common stock were excluded from the calculation since they would have had an antidilutive effect on diluted income (loss) per common share.
