Earnings Per Share [Abstract]

Earnings per share

Earnings per share

Basic earnings / (loss) per share are computed by dividing net income / (loss) for the period by the weighted-average number of ordinary shares outstanding, net of Treasury shares and shares held in ESOP. Diluted earnings / (loss) per share are computed by dividing net income / (loss) for the period by the weighted average number of ordinary shares outstanding and the dilutive ordinary share equivalents.

Basic and diluted earnings / (loss) per share were calculated as follows:

						Years ended December 31,
			In millions except share and per-share data			2024						2023						2022
			Basic (loss) / earnings:
			Net income / (loss) from continuing operations			$	18.3					$	(2.6)					$	32.0
			Net (loss) / income from discontinued operations			0.1						0.7						(5.1)
			Net income / (loss)			$	18.4					$	(1.9)					$	26.9
			Weighted average number of £0.50 ordinary shares:
			For basic earnings / (loss) per share			26,804,873						26,897,556						27,304,847
			Dilutive effect of potential common stock			279,028						123,403						236,355
			For diluted earnings / (loss) per share			27,083,901						27,020,959						27,541,202
			Earnings / (loss) per share using weighted average number of ordinary shares outstanding:(1)(2)
			Basic earnings / (loss) from continuing operations			$	0.68					$	(0.10)					$	1.17
			Basic (loss) / earnings from discontinued operations			$	—					$	0.03					$	(0.19)
			Basic earnings / (loss) per ordinary share			$	0.69					$	(0.07)					$	0.99
			Diluted earnings / (loss) from continuing operations			$	0.68					$	(0.10)					$	1.16
			Diluted (loss) / earnings from discontinued operations			$	—					$	0.03					$	(0.19)
			Diluted earnings / (loss) per ordinary share			$	0.68					$	(0.07)					$	0.98

(1) The calculation of earnings / (loss) per share is performed separately for continuing and discontinued operations. As a result, the sum of the two in any particular year may not equal the earnings-per-share amount in total.

(2) The loss per share for continuing operations in 2023 has not been diluted, since the incremental shares

included in the weighted-average number of shares outstanding would have been anti-dilutive.
