This figure has been reduced since the last block list review to reflect the number of share options that remain in existence under the 2005 EMI Scheme. This change is due share options issued under the 2005 EMI Scheme having lapsed due to employees leaving the Company. No new share options will be issued under the 2005 EMI Scheme.
