Basic earnings per share are based on profit for the year attributable to ordinary shareholders of £2,713 million (2008: £2,457 million) and 1,980 million (2008: 1,993 million) ordinary shares of 25p each, being the weighted average number of shares in issue during the year (excluding shares held as treasury shares).
For the calculation of diluted earnings per share, the weighted average number of shares in issue is increased to 1,991 million (2008: 2,005 million) to reflect the potential dilutive effect of employee share schemes.
