Explanatory notes
Annual Report and Accounts (Resolutions 1 and 2)
The Directors of the Company are required by the Companies Act 1985 to lay the accounts of the Company for the financial year ended 31 December 2002, the report of the Directors and the report of the auditors of the Company on those accounts before the shareholders at this Annual General Meeting. The Company is also required to specifically lay the report of the Remuneration Committee included in the accounts before the shareholders at this Annual General Meeting.
Re-election of Directors (Resolutions 3 and 4)
The Company’s Articles of Association require at least one third of the Directors to be subject to re-election at each Annual General Meeting. Resolutions 3 and 4 deal with these re-elections.
Ratification and remuneration of Auditors (Resolution 5)
The Company is required to appoint auditors at each general meeting at which accounts are laid, such auditors to hold office until the next such meeting. Resolution 5 proposes the ratification of the Directors’ appointment of Deloitte & Touche as auditors of the Company and authorises the Directors to determine the auditors’ remuneration for the ensuing year.
Resolutions 1-5 above are known as ordinary business of the meeting and will be proposed as ordinary resolutions. At least 50% of the votes cast must support these resolutions.
3
Authority to purchase Company’s own shares (Resolution 6)
In certain circumstances it may be advantageous for the Company to purchase its own shares and Resolution 6 seeks authority from the shareholders to continue to do so. The Directors intend to seek renewal of these powers at subsequent Annual General Meetings. The Directors intend to exercise this power only when, in light of market conditions prevailing at the time, they believe that the effect of such purchases will be to increase earnings per share and is in the best interests of shareholders generally. Other investment opportunities, appropriate gearing levels and the overall position of the Company will be taken into account before deciding upon this course of action. Any shares purchased in this way will be cancelled and the number of shares in issue will be accordingly reduced.
As at 28 March 2003, there are outstanding options to subscribe for 5.3 million ordinary shares, representing approximately 4.55% of the issued ordinary share capital of the Company. As at 28 March 2003 there are no warrants to subscribe for equity shares outstanding. If the proposed authority to purchase its own shares is fully exercised by the Company, the deemed outstanding options will represent approximately 5.35% of the issued ordinary share capital of the Company.
Resolution 6 is regarded as special business of the meeting and will be proposed as a special resolution. At least 75% of the votes cast must support the resolution in order for the resolution to be passed.
