Note 13. Net Loss per Share

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:


	Year Ended December 31,
	2022			2021
Net loss attributable to common stockholders	$	(19,914	)	$	(19,601	)
Weighted average number of shares of common stock		10,159			9,374
Basic and diluted net loss per share	$	(1.96	)	$	(2.09	)

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 708 shares of underlying unvested restricted stock awards and units and 1,202 outstanding stock options for the year ended December 31, 2022 and 1,332 shares of underlying unvested restricted stock awards and 653 outstanding stock options for the year ended December 31, 2021 from its net loss per diluted share calculations because their effect was anti-dilutive.

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


	Year Ended December 31,
	2022		2021
Restricted stock awards and units		929		1,142
Outstanding stock options		1,149		491
Total		2,078		1,633
