Net income (loss) per share

The following table presents the calculation of basic and diluted net income (loss) per share:


	Three Months Ended September 30,				Nine Months Ended September 30,
	2022		2021		2022		2021
Numerator:
Net income (loss)	$	(75.7)	$	(32.7)	$	(135.8)	$	41.6

Denominator:
Weighted-average number of shares—basic	49.9		53.7		50.2		53.6
Dilutive securities—equity awards	—		—		—		0.7
Weighted-average number of shares—diluted	49.9		53.7		50.2		54.3

Net income (loss) per share - basic	$	(1.52)	$	(0.61)	$	(2.71)	$	0.78
Net income (loss) per share - diluted	$	(1.52)	$	(0.61)	$	(2.71)	$	0.77

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per share is computed using the treasury method by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period, adjusted for the potential dilutive effect of other securities if such securities were converted or exercised and are not anti-dilutive. No adjustment for the potential dilutive effect of dilutive securities is reported for the three and nine months ended September 30, 2022 as the effect would have been anti-dilutive due to the Company's net loss.

In certain instances, awards may be anti-dilutive even if the average market price exceeds the exercise price when the sum of the assumed proceeds exceeds the difference between the market price and the exercise price. The following table presents the share-based awards that are not considered in the diluted income (loss) per share calculation generally because the exercise price of the awards was greater than the average per share closing price during the three and nine months ended September 30, 2022 and 2021:


	Three Months Ended September 30,		Nine Months Ended September 30,
	2022	2021	2022	2021
Anti-dilutive stock awards	3.3	1.4	2.6	0.6
