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.
