3. Net Loss per Share

Net Loss per Share Attributable to Common Stockholders

The following table sets forth the computation of basic and diluted net loss per share of common stock (in thousands, except share and per share data):

	Three Months Ended June 30,						Six Months Ended June 30,
	2019			2020			2019			2020
Net loss and comprehensive loss	$	(7,255	)	$	(8,295	)	$	(15,974	)	$	(15,387	)
Weighted-average shares used in computing net loss per share		18,580,430			23,355,418			18,578,091			21,786,946
Net loss per share, basic and diluted	$	(0.39	)	$	(0.36	)	$	(0.86	)	$	(0.71	)

The Company’s potentially dilutive securities, which include stock options and unvested restricted stock units, have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect.
