Basic EPS amounts are calculated by dividing net income (loss) allocated to common stockholders by the weighted average number of common shares outstanding. Diluted EPS amounts assume the issuance of common stock for all potentially dilutive common shares outstanding.

The following table shows the basic and diluted earnings (loss) per share for 2023, 2022, and 2021:


	For the year ended December 31, 2023
	Net Loss			Shares (in millions)	Per Share
Net loss attributable to Century stockholders	$	(43.1)
Amount allocated to common stockholders	100		%




Basic and Diluted EPS:(1)	$	(43.1)		92.4	$	(0.47)


	For the year ended December 31, 2022
	Net Loss			Shares (in millions)	Per Share
Net loss attributable to Century stockholders	$	(14.1)
Amount allocated to common stockholders	100		%




Basic and Diluted EPS:(1)	$	(14.1)		91.4	$	(0.15)


	For the year ended December 31, 2021
	Net Loss			Shares (in millions)	Per Share
Net loss attributable to Century stockholders	$	(167.1)
Amount allocated to common stockholders	100		%

Basic and Diluted EPS:(1)	$	(167.1)		90.2	$	(1.85)


Securities excluded from the calculation of diluted EPS (in millions)(1):	2023	2022	2021
Share-based compensation	1.0	1.7	2.7
Convertible preferred shares	5.4	5.8	6.3
Convertible senior notes	4.6	4.6	4.8

(1)In periods when we report a net loss, all share-based compensation awards, convertible preferred shares and convertible senior notes are excluded from the calculation of diluted weighted average shares outstanding because of their anti-dilutive effect on earnings (loss) per share.
