I wouldn't imagine there would be a preconceived notion, for example, on the exchange rate, and taking a look at the four-year approach. Mind you, you have more recent figures to base it on, but, nonetheless, the almost 5¢ gap is significant. I'd imagine that would also influence the figures for how many exports the Canadian economy would be able to produce, or to what degree it would be able to produce exports.
Why is there such a huge difference on that? I don't know if Mr. Matier wants to get in on this.
