This is an exercise we need to do on an ongoing basis. Some licences have been procured at a certain time, and they may not be the ones we need anymore. We have to keep hygiene around the using of a licence. I think it's an excellent question. Part of managing a complex IT infrastructure is really making sure we are using what we have procured. We revamp our arrangement with the vendor if we don't need these licences any more.
Maybe Mr. Nadeau will have specific examples in his area of where he's keeping this under control.
