9 Earnings per share

Basic earnings per share is calculated by dividing the earnings attributable to ordinary shareholders by the weighted average number of ordinary shares in issue during the year, excluding those held by the Employee Share Ownership Plan trusts (note 25), which are treated as cancelled. For diluted earnings per share, the weighted average number of ordinary shares in issue is adjusted to assume conversion of all potential dilutive ordinary shares. These represent share options granted to employees where the exercise price is less than the average market price of the Company's ordinary shares during the year.

Underlying earnings per share is provided by excluding the effect of any gain or loss on the sale of properties, impairment of goodwill, financing fair value movements and one-off items that are material and infrequent in nature. This alternative measure of earnings per share is presented to reflect the Group’s underlying trading performance.

All operations are continuing for the periods presented.
