The following is a reconciliation of the numerator (net loss) and the denominator (number of shares) used in the basic and diluted net loss per share calculations:

	Three Months Ended June 30,						Six Months Ended June 30,
	2022			2021			2022			2021
Net loss	$	(6,759	)	$	(4,362	)	$	(13,433	)	$	(9,544	)
Weighted average number of shares of common stock		10,073			9,296			10,020			9,242
Basic and diluted net loss per share	$	(0.67	)	$	(0.47	)	$	(1.34	)	$	(1.03	)

The Company’s basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period.

As the Company has reported a net loss for all periods presented, basic and diluted net loss per share attributable to common stockholders are the same for those periods. The Company excluded 934 shares of underlying unvested restricted stock awards and units and 1,193 outstanding stock options for the three and six months ended June 30, 2022 and 1,573 shares of underlying unvested restricted stock awards and 629 outstanding stock options for the three and six months ended June 30, 2021 from its net loss per diluted share calculations because their effect was anti-dilutive.

The anti-dilutive weighted average shares excluded from the diluted net loss per share diluted shares calculations were:

	Three Months Ended June 30,				Six Months Ended June 30,
	2022		2021		2022		2021
Restricted stock awards and units		995		1,417		1,033		1,431
Outstanding stock options		1,140		537		1,096		328
Total		2,135		1,954		2,129		1,759
