15.Net Loss per Share

The following table sets forth the computation of basic and diluted net loss per share for the three and nine months ended September 30, 2019 and 2018 (in thousands, except per share data):


	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2019		2018		2019		2018
Numerator:
Net loss	$	(8,203)	$	(7,498)	$	(40,892)	$	(35,875)
Denominator:
Weighted–average shares used to compute basic and diluted net loss per share		110,831		104,032		109,147		101,369
Basic and diluted net loss per share	$	(0.07)	$	(0.07)	$	(0.37)	$	(0.35)

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 the three and nine months ended September 30, 2019 and 2018, 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 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):


	September 30,	September 30,
	2019	2018
Stock options outstanding, net of unvested exercised stock options	2,929,095	5,122,470
Unvested restricted stock units	13,806,088	12,791,608
ESPP shares	194,622	194,366
Stock-settled bonus shares	499,612	740,489
Total potentially dilutive securities	17,429,417	18,848,933
