The following table summarizes the computation of basic and diluted net loss per share attributable to common shareholders of the Company:

	Year Ended December 31,
	2020			2019
	(in thousands, except share and per share data)
Numerator:
Net loss attributable to common shareholders	$	(53,417	)	$	(27,216	)
Net loss attributable to common shareholders—basic and diluted	$	(53,417	)	$	(27,216	)
Denominator:
Weighted-average number of common shares outstanding— basic and diluted		20,045,602			1,528,374
Net loss per share attributable to common shareholders— basic and diluted	$	(2.66	)	$	(17.81	)

The Company’s potentially dilutive securities, which include Convertible Preferred Shares and stock options, have been excluded from the computation of diluted net loss per share attributable to common shareholders as the effect would be to reduce the net loss per share attributable to common shareholders. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common shareholders is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to common shareholders for the periods indicated because including them would have had an anti-dilutive effect:

	Year Ended December 31,

Series A preferred shares		—		11,090,135
Series B preferred shares		—		10,468,258
