Basic (loss)/earnings per share is calculated by dividing the profit or loss for the period attributable to equity shareholders by the weighted average number of the Company's ordinary shares in issue during the period. The weighted average number of the Company's ordinary shares in issue during the period excludes 3,962,756 shares (2008: 4,002,675 shares; 2007: 4,331,018 shares), being the weighted average number of own shares held during the period.
Diluted earnings per share takes into account the dilutive effect of potential ordinary shares. The weighted average number of the Company's ordinary shares used in the calculation of diluted earnings per share excludes the effect of:
