Net Loss per Share Attributable to Common Stockholders

Note 13. Net Loss per Share Attributable to Common Stockholders

Basic net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding for the period. Because the Company reported a net loss for the three and nine months ended September 30, 2019 and 2018, the number of shares used to calculate diluted net loss per common share is the same as the number of shares used to calculate basic net loss per common share for those periods presented because the potentially dilutive shares would have been antidilutive if included in the calculation.

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

	Three Months Ended September 30,						Nine Months Ended September 30,
	2019			2018			2019			2018
Numerator:
Net loss attributable to common stockholders	$	(6,885	)	$	(3,641	)	$	(18,439	)	$	(16,331	)
Denominator:
Weighted-average shares outstanding		31,134,009			3,065,386			13,614,087			3,063,418
Less weighted-average shares subject to repurchase		(326	)		(130	)		(643	)		(954	)
Weighted-average shares outstanding used in computing net loss per share attributable to common stockholders — basic and diluted		31,133,683			3,065,256			13,613,444			3,062,464
Net loss per share attributable to common stockholders — basic and diluted	$	(0.22	)	$	(1.19	)	$	(1.35	)	$	(5.33	)

The following outstanding shares of potentially dilutive securities 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:
