Mr. Dean Sullivan:

As I said, it would have to be teased out further whether in the depths of history there was some involvement at some point, given the nature of these types of firms and given that they have auditing rules and so on. It may have been involved at some point but I can check that. PwC is satisfied that there is no current conflict, insofar as there may be Chinese walls or similar arrangements, as there often are in this situation.
