13. Additional information:

On 1st November 2010, Silchester International Investors Limited ("Silchester Limited") transferred its regulated business to Silchester International Investors LLP ("Silchester LLP"). On the same day, Silchester Limited changed its name to Silchester Partners Limited. All employees of Silchester Limited, including all portfolio managers, investment analysts and members of its administration and operations teams, became partners or employees of Silchester LLP. Silchester LLP acts as investment manager for the clients detailed in Question 4 above (the "Clients"). In acting for the Clients, Silchester LLP is given full discretion over their investments and are empowered to vote on their behalf. However, Silchester LLP does not act as the Clients' custodian and therefore shares are not held in Silchester LLP's name but in the name of each Client's custodian bank. This notification was therefore triggered by the change in the legal structure of the investment management firm on 1st November 2010 rather than trading activity in the underlying shares.
