It may not be the maintenance. At some point that can become an issue, because they can often move away from it, but what it does to us generally in the life cycle is that rather than our taking it away so they can't reuse it or there being the threat that somebody in Canadian industry will be able to compete against them, we're licensing it for the purposes of maintaining it and having our systems maintained. There still can be an issue when we put an in-service support contract up for competition, because their competitor can get access to their IP.
