12.	Net Loss Per Share Attributable to Common Shareholders

Net Loss Per Share

The following table sets forth the computation of the basic and diluted net loss per share attributable to common shareholders (in thousands, except shares and per share amounts):

	Three Months Ended June 30,						Six Months Ended June 30,
	2019			2018			2019			2018
	(unaudited)
Net loss	$	(15,659	)	$	(12,493	)	$	(34,045	)	$	(24,884	)
Fair value adjustments to redemption value for Series E-1 convertible preferred stock options		(710	)		(2	)		(964	)		2
Net loss attributable to common shareholders, basic and diluted	$	(16,369	)	$	(12,495	)	$	(35,009	)	$	(24,882	)
Weighted-average shares used in computing net loss per share		13,279,324			12,385,888			13,074,692			12,334,227
Net loss per share attributable to common shareholders, basic and diluted	$	(1.23	)	$	(1.01	)	$	(2.68	)	$	(2.02	)

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 periods presented, as they had an anti-dilutive effect:
