Well, first of all, I think the industry has had a different view on that issue. They think we should be able to apply the results of an article XXVIII against the U.S., and they have some of their own legal advice that supports that, so they've maintained that view.
There have also been discussions about the possibility of having a separate negotiation with the U.S. to try to address the issue, and they have at some times suggested that might be an avenue to follow. So we've had fairly extensive discussions about this.
