Net Loss per Share Attributable to Common Stockholders

Net Loss per Share Attributable to Common Stockholders

The following table sets forth the computation of basic and diluted net loss per share attributable to common stockholders:

	Year Ended December 31,
	2019				2018		2017
	Class A		Class B		Common		Common
	(in thousands, except per share data)
Net loss attributable to common stockholders	$	(18,259)	$	(87,569)	$	(87,164)	$	(10,748)
Weighted-average shares used in computing net loss per share attributable to common stockholders, basic and diluted	25,243		121,063		80,981		77,147
Net loss per share attributable to common stockholders, basic and diluted	$	(0.72)	$	(0.72)	$	(1.08)	$	(0.14)

Since the Company was in a loss position for all periods presented, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential common shares outstanding would have been antidilutive. The potential shares of common stock that were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented because including them would have been antidilutive are as follows:
