Note 13—Income (Loss) per Share

Basic income (loss) per share is computed by dividing net income (loss) by the sum of the weighted-average number of common shares outstanding and the weighted-average number of shares issuable under the common stock warrants, representing 345 thousand shares and 749 thousand shares during the three months ended March 31, 2016 and 2015, respectively. The common stock warrants are included in the calculation of basic income (loss) per share because they are issuable for minimal consideration. The following table sets forth the computation of basic and diluted earnings per share (in thousands, except per share amounts):



	Three Months Ended March 31,
	2016			2015
Net income (loss)	$	(18,673	)	$	462
Undistributed income allocated to participating securities	—			8
Net income (loss) attributable to common stockholders	$	(18,673	)	$	454

Basic weighted-average common stock shares outstanding	40,974			37,188
Add: dilutive effects of common stock equivalents (1)	—			193
Diluted weighted-average common stock shares outstanding	40,974			37,381

Basic income (loss) per common share	$	(0.46	)	$	0.01
Diluted income (loss) per common share	(0.46		)	0.01

(1)	Entities with a net loss from continuing operations are prohibited from including potential common shares in the computation of diluted per share amounts. We have utilized the basic shares outstanding to calculate both basic and diluted loss per share for the three months ended March 31, 2016.

For the three months ended March 31, 2016, our weighted-average potentially dilutive securities excluded from the calculation of diluted shares outstanding consisted of 439 thousand shares of unvested restricted stock and 658 thousand stock options, respectively. For the three months ended March 31, 2015, our weighted-average potentially dilutive securities excluded from the calculation of diluted shares outstanding consisted of no shares of unvested restricted stock and 15 thousand stock options, respectively.
