15. Net Loss per Share

The following table sets forth the computation of basic and diluted net loss per share for 2015, 2014 and 2013 (in thousands, except per share data):


	Year ended December 31,
	2015		2014		2013
Numerator:
Net loss	$	(84,482)	$	(61,889)	$	(32,497)
Denominator:
Weighted–average shares outstanding		78,867		48,332		13,009
Less: weighted average shares subject to repurchase		(112)		(815)		(3,056)
Weighted–average shares used to compute basic and diluted net
loss per share		78,755		47,517		9,953
Basic and diluted net loss per share	$	(1.07)	$	(1.30)	$	(3.27)

Basic net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding for the period. Because we have reported a net loss for 2015, 2014 and 2013, the number of shares used to calculate diluted net loss per common share is the same as the number of shares used to calculate basic net loss per common share for those periods presented because the potentially dilutive shares would have been anti-dilutive if included in the calculation.

The following potentially dilutive securities outstanding have been excluded from the computation of diluted weighted-average shares outstanding because such securities have an antidilutive impact due to losses reported (in common stock equivalent shares):
