NOTE 6. NET LOSS PER SHARE

Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period, less shares subject to repurchase, and excludes any dilutive effects of stock-based awards and warrants. Diluted net loss per common share is computed giving effect to all potential dilutive common shares, including common stock issuable upon exercise of stock options, and unvested restricted common stock and stock units. As the Company had net losses for the three months ended March 31, 2018 and 2017, all potential common shares were determined to be anti-dilutive. The following table sets forth the computation of net loss per common share (in thousands, except share and per share amounts):


	Three Months Ended
	March 31,
	2018		2017
Numerator:
Net loss	$	(17,019)	$	(28,008)
Denominator:
Weighted average common shares outstanding - basic and diluted		47,559,366		47,343,234
Net loss per share - basic and diluted	$	(0.36)	$	(0.59)

For the three months ended March 31, 2018 and 2017, the total number of securities that could potentially dilute basic net loss per share in the future that were not included in the computation of diluted net loss per share because the effect would have been antidilutive was 8.0 million and 6.1 million, respectively.
