Net Loss per Share

Net loss per share

Basic and diluted net loss per share attributable to common stockholders was calculated as follows:


	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Numerator:
Net loss attributable to common stockholders ($ in millions)	$	(55.6)	$	(21.0)	$	(104.6)	$	(57.5)
Denominator:
Weighted average common shares outstanding — basic and diluted	61,444,958		11,891,979		60,643,764		11,750,198
Net loss per share attributable to common stockholders — basic and diluted	$	(0.90)	$	(1.77)	$	(1.72)	$	(4.89)

The Company’s potentially dilutive securities, which include stock options, unvested RSUs and preferred 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 unvested RSUs and outstanding options to purchase common stock of 6,089,738 and 4,578,520 for the six months ended June 30, 2021 and 2020, respectively, 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.
