Earnings per share [abstract] |
Earnings per share | The Group calculates earnings per share in accordance with IAS 33. Basic income per share is calculated based on the weighted average common shares outstanding for the period presented. The weighted average number of shares outstanding is calculated by time-apportioning the shares outstanding during the year. For the purpose of calculating diluted earnings per share, the weighted average number of ordinary shares outstanding during the financial year has been adjusted for the dilutive effects of all potential ordinary shares and share options granted to employees. Following the decision to terminate Luxfer Holdings PLC's ADS facility, each £0.50 ordinary share of Luxfer Holdings PLC are now listed and traded directly on the New York Stock Exchange (NYSE). Management believe the use of non-GAAP financial measures such as adjusted earnings, as reconciled in the table below, per share more closely reflects the underlying earnings per share performance.
