10. Net Loss Per Share

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

	Three Month Ended						Nine Month Ended
	September 30,						September 30,
	2018			2017			2018			2017
Net loss	$	(2,065	)	$	(1,005	)	$	(4,266	)	$	(4,362	)
Weighted-average common shares outstanding		34,435,298			4,709,642			33,925,443			4,603,146
Less: Shares subject to repurchase		—			—			—			—
Weighted-average shares outstanding		34,435,298			4,709,642			33,925,443			4,603,146
Net loss per share, basic and diluted	$	(0.06	)	$	(0.21	)	$	(0.13	)	$	(0.95	)

Basic net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding for the period. Basic and diluted net loss per share is presented in conformity with the two-class method required for participating securities. Prior to the IPO, the holders of the Company’s convertible preferred stock were entitled to receive non-cumulative dividends, payable prior and in preference to any dividends on shares of the common stock. Any additional dividends would be distributed among the holders of convertible preferred stock and common stock pro rata, assuming the conversion of all convertible preferred stock into common stock. After the IPO, all convertible preferred stocks were converted to common stock and the Company has one class of stock issued and outstanding.

The following potentially dilutive securities outstanding have been excluded from the computation of diluted weighted-average shares outstanding because such securities have an antidilutive impact due to losses reported (in common stock equivalent shares):

	As of		As of
	September 30,		December 31,
	2018		2017
