	Three Months Ended March 31,
	2024		2023
Numerator:
Net loss attributable to common stockholders ($ in millions)	$	(47.3)	$	(65.8)
Denominator:
Weighted average common shares outstanding — basic and diluted	70,284,486		69,334,103
Net loss per share attributable to common stockholders — basic and diluted	$	(0.67)	$	(0.95)

The Company’s potentially dilutive securities, which include stock options, unvested RSUs and warrants for common stock, have been excluded from the computation of diluted net loss per share as the effect would be anti-dilutive. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders 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 stockholders for the periods indicated because including them would have had an anti-dilutive effect.
