Yes, there are distinctions between the pension regimes of the various provinces in Canada versus the federal regime. There are differences between those Canadian systems and systems of other countries. And in the submissions we've made, we've drawn out some of the differences in those various systems.
For example, we believe today that the discount rate set federally has a significant negative bias. It is based off Government of Canada rates, as I said, at a point in time, and we believe that a truer measure of the discount rate is to look at investment grade bond yields over a smooth period of time. So today the federal government's approach would result in a discount rate that is approximately 4.5%. If we were to use that investment grade bond approach, it would result in a higher rate by 200 or 300 basis points, similar to U.S. and U.K. regimes.
