Well, we don't know exactly what's happening, although we do know that some of the players who are in gas retailing are in the last few months showing higher profits than they have ever shown, so we would applaud the idea of doing some research into this rocket-and-feather effect. In fact, we at CAA were talking about commissioning our own study and putting it out in the public domain, to understand what's going on.
If you see what is going on in pricing in the U.S., it's not so much the rocket and feather. It looks as though prices have gone down by close to the proportion that oil prices have gone down. We think there could be something going on in Canada. We think an academic investigation into that question is probably worthwhile.
