Dear Sir/Madam

Companies Act 1985
Disclosures of Interests in Voting Shares - Changes in Registered Holders

In compliance with Part IV of the above Act, as amended, I inform you that
following a change in Trustee and Custodian, the registration details for some
funds currently managed by Prudential plc and Group Companies have changed from
that previously notified to you.  As a direct result, the names of the
registered holders which comprise our notifiable interest in the voting shares
in your company will now be as listed on the attached report.

Please note that the following changes have taken effect:

DEXIA BANK INTL

Has been changed to:

BK OF NEW YORK(NOMS)LTD/636922

It must be stressed that is not a change to our notifiable interest in the
voting shares of your company that has generated this notification, but merely a
change in registration details.


Yours faithfully



Richard Harding
For and on behalf of Prudential plc
