Computation of Basic and Diluted Net (Loss) Income Per Share Attributable to Common Stockholders

Basic and diluted net (loss) income per share attributable to common stockholders are computed as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2014			2013			2014			2013
Net (loss) income	$	(3,645	)	$	5,337		$	(7,028	)	$	2,705
Add back: extinguishment of preferred shares		—			—			—			891
Less: net income attributable to participating securities		—			(3,869	)		—			(2,656	)
Net (loss) income attributable to common stockholders - Basic		(3,645	)		1,468			(7,028	)		940
Add: net income attributable to participating securities		—			3,869			—			2,656
Net (loss) income attributable to common stockholders - Diluted	$	(3,645	)	$	5,337		$	(7,028	)	$	3,596
Net (loss) income per share attributable to common stockholders

Weighted-average common shares outstanding attributable to common stockholders:

Schedule of Anti-Dilutive Common Stock Equivalents Excluded from Calculations of Diluted Net Loss Per Share

Securities outstanding at the end of the respective periods presented below, that could potentially dilute basic earnings per share in the future, that were not included in the computation of diluted net loss per share because to do so would have been antidilutive are as follows:

Convertible preferred stock		—		—
Common stock options		1,058,160		—
