Well, as I said before, we have only one tool and that is the setting of the overnight interest rate, and we've been doing that in such a way as to keep Canadian rates right across the curve. It's very important that it's not just the overnight rate, but it's right out to 10 years and even to 30 years.
We've kept reducing our rates relative to the United States over this very difficult period of adjustment, and we really started in 2004 to be very careful in that regard, but that is the only tool we have to operate with.
