Earnings Per Share [Abstract]  
Earnings per share Earnings per share
Basic earnings per share are computed by dividing net income or loss for the period by the weighted-average number of ordinary shares outstanding, net of treasury shares and shares held in ESOP. Diluted earnings per share are computed by dividing net income or loss for the period by the weighted average number of ordinary shares outstanding and the dilutive ordinary shares equivalents.
Basic and diluted earnings per share were calculated as follows:

Basic earnings:

Net (loss) / income from discontinued operations(0.5)(1.2)(0.9)3.8 
Net income$8.0 $4.8 $24.9 $30.3

Earnings / (loss) per share using weighted average number of ordinary shares outstanding(1):
Basic earnings per ordinary share for continuing operations$0.31 $0.22 $0.94 $0.96 
Basic (loss) / earnings per ordinary share for discontinued operations(0.02)(0.04)(0.03)0.14 
Basic earnings per ordinary share$0.29 $0.17 $0.91 $1.09 
Diluted earnings per ordinary share for continuing operations$0.31 $0.21 $0.93 $0.94 
Diluted (loss) / earnings per ordinary share for discontinued operations(0.02)(0.04)(0.03)0.14 
Diluted earnings per ordinary share$0.29 $0.17 $0.90 $1.08 
(1) The calculation of earnings per share is performed separately for continuing and discontinued operations. As a result, the sum of the two in any particular period may not equal the earnings-per-share amount in total
In the third quarter of 2022 and 2021 and year-to-date 2022, basic average shares outstanding and diluted average shares outstanding were the same for discontinued operations because the effect of potential shares of common stock was anti-dilutive since the Company generated a net loss from discontinued operations.
