4.     Net Loss per Share

Basic net loss per share is computed by dividing net loss by the weighted average number of shares of common stock of the Company outstanding during the period. Diluted net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period plus the impact of dilutive securities using the treasury stock method, to the extent that they are not anti-dilutive.

The following table presents the calculation of basic and diluted net loss per share for the Company’s common stock:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2020		2019		2020		2019
Numerator (basic and diluted):
Net loss	$	(14,310)	$	(6,529)	$	(28,747)	$	(17,508)
Denominator (basic and diluted):
Weighted average shares of common stock outstanding, basic and diluted		21,556,646		20,482,032		21,465,772		20,433,564
Net loss per share, basic and diluted	$	(0.66)	$	(0.32)	$	(1.34)	$	(0.86)
