Yes, the Company usually pays dividends twice yearly in January and August/September. Details of the amount of any dividend to be paid appear in the preliminary and half year financial results which are announced in June/July and November/December each year.

Shareholders may choose to have their dividends proceeds reinvested in Atkins shares by participating in our Dividend Reinvestment Plan ("DRIP" or "the Plan"). Any shareholder wishing to obtain details of the Plan should contact our registrar.

Yes. You should complete a Dividend Payment Instruction Form and return it to our registrar. These forms are sent with each dividend payment or can be downloaded by accessing My Atkins Shares, our share portal if you have registered to use this service.

The Company provides a consolidated tax voucher once a year to those shareholders who have their dividends paid directly to their bank or building society account. Shareholders who have a dividend cheque sent to their registered address receive a tax voucher with each payment.

Contact our registrar who will issue a duplicate. There is an administration charge of £16.50 for the first voucher and then £3 for each additional voucher.

You should contact our registrar. Alternatively, you can check your shareholding online by accessing My Atkins Shares, our share portal if you have registered to use this service.

You should contact our registrar and ask for a replacement. You will be sent a form of indemnity to sign and return. There may be an indemnity charge for a lost or destroyed share certificate where the value of the shares exceeds £100. A new certificate will then be sent to you. Please note that our registrar makes a charge for this service. If you hold your shares through a CREST account, you will not hold any share certificate(s). Instead, you should receive a statement indicating the number of shares you hold from the broker or financial institution through whom you bought the shares. If you lose this, replacement statements can be issued as required by contacting your service provider.

Inform our registrar by sending a certified copy of the death certificate together with the original Grant of Probate (or a sealed office copy) or the Letters of Administration. The name of the deceased's personal representative(s) will be substituted on our share register while the estate is finalised. In the case of a joint holding only the certified death certificate is required together with the share certificates in order to register the shares into the sole survivor's name.

There are options for the person entitled to the shares to be registered as the holder of them or for the shares to be transferred or sold. Please contact our registrar who will provide further details.

You should complete a stock transfer form and send it with your share certificate to our registrar. Copies of these forms can be downloaded by accessing My Atkins Shares, our share portal.

You should write to our registrar. If you move house, then you should give details of both your old and new address. If your name has changed, then you should enclose a copy of your marriage certificate in the case of marriage or a copy of the legal document confirming your name change in other cases together with your share certificate(s) for amendment. Alternatively you can amend your personal details by accessing My Atkins Shares, our share portal.

As a shareholder, each year you will be invited to attend our Annual General Meeting (AGM). If there is a particularly important matter to decide that cannot wait until the next AGM, shareholders may be called to an Extraordinary General Meeting.

Our next Annual General Meeting will be held in the summer of 2013.

The Annual General Meeting is the main shareholder event of the year. The meeting reviews our performance over the past year and provides an opportunity for shareholders to ask questions and vote on key issues. These include, for example, the adoption of our Annual Report, the election of directors and the re-appointment of auditors. Shareholders are given the opportunity to ask questions relating to the items on the meeting agenda.

Shareholders will also have the opportunity to ask questions about the Company and its activities. There may also be special business to vote on, for example, proposals to change the Company's Articles of Association, which govern the Company's activities.

If you cannot attend the meeting in person, you can still express your views on the matters for discussion at the meeting. The Company's Articles of Association provide that all substantive decisions (i.e. all the items listed in the Notice of a General Meeting sent out to members) must be approved by shareholders. Before the meeting, if your shares are registered in your own name, we will send you a proxy voting form, or you can vote online by accessing My Atkins Shares, our share portal. You should indicate whether you wish to vote for, against or withhold your vote on each of the items (resolutions) due to be decided at the meeting. You may also appoint the Chairman of the meeting, to cast your proxy vote the way you want, or for the Chairman to vote using his discretion.

Alternatively, you may name someone else to go to the meeting and vote for you – your proxy. If your shares are registered in the name of your nominee, the nominee will receive the proxy form.

Please access the Financials section of our website for presentations given by the Company.

We are obliged by law to make our share register available to other organisations who may then use it for a mailing list. If you wish to limit the receipt of unsolicited mail you may do so by registering with The Mailing Preference Services (MPS). MPS will then notify the bodies that support its service that you do not wish to receive unsolicited mail. Registration can be made in writing to: The Mailing Preference Service (MPS), Freepost 29 LON20771, London W1E 0ZT or online at www.mpsonline.org.uk.

We support ShareGift, the charity share donation scheme administered by The Orr Mackintosh Foundation (registered charity number 1052686). Through ShareGift, shareholders who have a very small number of shares which might be considered uneconomic to sell are able to donate them to charity. Donated shares are aggregated and sold by ShareGift, the proceeds being passed on to a wide range of UK charities. Donating shares to charity gives rise neither to a gain nor loss for UK Capital Gains purposes and UK taxpayers may also be able to claim income tax relief on such gifts of shares.

ShareGift transfer forms are available from our registrar.

Even if the share certificate has been lost or destroyed, the transfer can be completed. The service is usually free, however there may be an indemnity charge for a lost or destroyed share certificate where the value of the shares exceeds £100. Further details about ShareGift can be obtained from www.ShareGift.org or at:
