Earnings Per Share [Abstract]

Net Loss Per Share and Net Loss Attributable to Common Stockholders

Net Loss Per Share and Net Loss Attributable to Common Stockholders

Earnings (loss) per share (EPS) is the amount of net income (loss) available to each share of common stock outstanding during the reporting period. Diluted EPS is the amount of net income (loss) available to each share of common stock outstanding during the reporting period, adjusted to include the effect of potentially dilutive common shares. Potentially dilutive common shares include incremental shares issued for stock options, convertible preferred stock (through December 11, 2014) and warrants to purchase common stock. Potentially dilutive common shares are excluded from the computation of dilutive EPS in periods in which the effect would be antidilutive.

We calculate EPS using the two-class method when applicable. The two-class method allocates net income that otherwise would have been available to common shareholders to holders of participating securities. All participating securities are excluded from basic weighted-average common shares outstanding. Prior to our Initial Public Offering (IPO), we considered all series of our convertible preferred stock to be participating securities. In conjunction with our IPO, all of our convertible preferred stock converted to common stock and all warrants to purchase convertible preferred stock were converted to warrants to purchase common stock. We had no participating securities as of March 31, 2015.

The following table details the computation of the basic and diluted net loss per share:

	Three Months Ended March 31,
	2015			2014
Net loss	$	(6,374	)	$	(7,299	)
Net loss available to common stockholders(1)	$	(6,374	)	$	(7,299	)
Weighted average common shares - Basic	371,959,312			55,780,644
Weighted average common shares - Diluted	371,959,312			55,780,644
Basic net loss per share attributable to common stockholders	$	(0.02	)	$	(0.13	)
Diluted net loss per share attributable to common stockholders	$	(0.02	)	$	(0.13	)

⁽¹⁾  In a period with net income, both earnings and dividends (if any) are allocated to participating securities. In a period with a net loss, only declared dividends (if any) are allocated to participating securities. There were no dividends declared in the three months ended March 31, 2014.
