If I could just add one point, in terms of who's responsible, Pierre is absolutely right.
I guess the point I was trying to make earlier was that we are trying to make sure that we show some leadership on this and that all of the management committee takes some accountability, perhaps a looser sense of accountability than what you've just described, but we do want to see the results. We want to see how we're doing and we want everybody to be collectively engaged in this.
