Note 12. Basic and Diluted Net Loss Per Share

Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period, less the weighted-average unvested common stock subject to repurchase or forfeiture as they are not deemed to be issued for accounting purposes. Diluted net loss per share is computed by giving effect to all potential shares of common stock, stock options, restricted stock units, and ESPP, to the extent dilutive. For the periods presented, all such common stock equivalents have been excluded from diluted net loss per share as the effect to net loss per share would be anti-dilutive.

The following table sets forth the computation of the Company’s basic and diluted net loss per share during the years ended December 31, 2017, 2016 and 2015 (in thousands, except per share data):

	Year Ended December 31,
	2017			2016			2015
Numerator
Net loss	$	(26,141	)	$	(29,309	)	$	(32,099	)
Denominator
Weighted-average common shares for basic and diluted net loss per share		76,281			72,994			70,069
Basic and diluted net loss per share	$	(0.34	)	$	(0.40	)	$	(0.46	)

The following table summarizes the potentially dilutive common shares that were excluded from diluted weighted-average common shares outstanding because including them would have had an anti-dilutive effect (in thousands):

	Year Ended December 31,
	2017		2016		2015
Shares of common stock subject to repurchase		—		—		2
Shares of common stock issuable under equity incentive plans outstanding		10,806		11,726		11,475
Potential common shares excluded from diluted net loss per share		10,806		11,726		11,477
