Net Loss Per Share

The following table sets forth the computation of the basic and diluted net loss per share attributable to common shareholders for the year ended December 31, 2019, 2018 and 2017, respectively (in thousands, except share and per share amounts):

	Year Ended December 31,
	2019			2018			2017
Net loss	$	(68,606	)	$	(46,447	)	$	(42,831	)
Fair value adjustments to redemption value for Series E-1 convertible preferred stock options		(964	)		102			135
Net loss attributable to common shareholders, basic and diluted	$	(69,570	)	$	(46,345	)	$	(42,696	)
Weighted-average shares used in computing net loss per share		69,165,315			12,629,778			12,196,998
Net loss per share attributable to common shareholders, basic and diluted	$	(1.01	)	$	(3.67	)	$	(3.50	)

Since we were in a loss position for all periods presented, basic net loss per share attributable to common shareholders is the same as diluted net loss per share attributable to common shareholders, as the inclusion of all potential shares of common stock outstanding would have been anti-dilutive. The following weighted-average common stock equivalents were excluded from the calculation of diluted net loss per share attributable to common shareholders for the year ended December 31, 2019, 2018 and 2017, respectively, as they had an anti-dilutive effect:

	Year Ended December 31,
	2019		2018		2017
Convertible preferred stock (on as if converted basis)		46,104,469		92,783,867		88,473,431
