I think that both debt dumping and double-dipping are important problems. We don't have any statistics on how much money is available. You can't find that out. But I think they're both substantial, and they both require action.
With respect to coming down to only borrowing money once and only getting a single deduction that you might take in Canada, well, all these companies are taking their single deduction in Canada anyway. So I don't think we would lose any additional revenue by restricting double-dipping. I think people will arrange their borrowings for a number of reasons, which include consideration of foreign currency risk, financial markets, and so on. And as long as they get one deduction, I think they've been treated fairly.
