Net Loss Per Share

3 Months Ended

Mar. 31, 2021

Basic loss per share is calculated by dividing net loss attributable to common stockholders by the weighted average shares outstanding during the period.

The following table sets forth the computation of basic and diluted net loss per share:


	Three Months Ended March 31,
(In millions, except per share data)	2020		2021
Basic and diluted net loss per share:
Net loss attributable to common stockholders	$	(48.2)	$	(64.0)
Weighted average shares outstanding:
Common stock	165.4		204.6
Number of shares used in per share computations	165.4		204.6
Net loss per share	$	(0.29)	$	(0.31)

Potential common share equivalents consist of shares issuable upon the exercise of stock options, vesting of restricted stock or purchase under the Employee Stock Purchase Plan (the "ESPP"), as well as contingent shares associated with our acquisition of Datapipe Parent, Inc. Since we were in a net loss position for both periods presented, basic net loss per share is the same as diluted net loss per share for both periods as the inclusion of all potential common shares outstanding would have been anti-dilutive. We excluded 25.0 million and 21.7 million potential common shares from the computation of dilutive loss per share for the three months ended March 31, 2020 and 2021, respectively, because the effect would have been anti-dilutive.
