15. Net Loss per Share

The following table sets forth the computation of basic and diluted net loss per share for 2016, 2015 and 2014 (in thousands, except per share data):

Numerator:
Net loss	$	(67,180)	$	(84,482)	$	(61,889)

Weighted–average shares outstanding		85,853		78,867		48,332
Less: weighted average shares subject to repurchase		(8)		(112)		(815)
Weighted–average shares used to compute basic and diluted net loss per share		85,845		78,755		47,517
Basic and diluted net loss per share	$	(0.78)	$	(1.07)	$	(1.30)

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 2016, 2015 and 2014, 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):
