Thanks very much for that explanation.
Mr. Macklem, you've talked before about government economic policy or fiscal policy, as I think you call it, being at cross purposes to monetary policy. We saw in the last few months of the year, as the year closed out, that the government's deficits over the last couple of years have been much higher than was originally anticipated. If that happens again, what impact will that have on your ability to lower interest rates in the short or medium term?
