    11. Additional Information
      Silchester International Investors LLP (“Silchester”) acts as investment
      manager for certain commingled funds (our “Clients”). No Client holds
      more than 5% of voting rights. In acting for our Clients, Silchester is
      given full discretion over their investments and is empowered to vote
      on their behalf. However, we do not act as our Clients’ custodian and
      therefore shares are not held in our name but in the name of each
      Client’s custodian bank. The change in Silchester's holdings was due to
      a series of transactions over a series of different trading days.
