I will start to answer your question, and then I will give the floor to my colleague, who works in the technical sector much more than I do.
I will tell you that we have achieved a great deal of progress since last year. As I said, we have drawn up a complete inventory with respect to the email systems, and we are now in the process of doing the same thing with the data centres and the networks.
We also have an operating model which enables us to get a very complete overall picture of the business's activities, over the long term.
I think I will ask Mr. Westcott to give you a brief explanation of what we have observed.
