I don't think we're looking at regulating derivatives any more than we have been.
CMHC was not part of this review. I would argue that derivatives were certainly a part of it, but I would suggest that subprime mortgage was probably at the heart of what happened. Fortunately, we had very minimal exposure—any Canadian bank had very minimal exposure—to subprime mortgages.
Derivatives are an effective tool. I used to use derivatives to hedge my production. It's a very effective tool, when you're looking at forward pricing, to put in puts and calls to make sure that you protect your downside and you protect your upside risks. They can be a very effective tool. They do get abused; I understand that. But CMHC was not part of this review.
