No, they don't, because the beauty of the way we manage the reserves—and we're somewhat unique in this way—is, as Mr. Marion mentioned, by doing an asset and liability hedge. If we own a 10-year U.S. treasury, for example, that is funded with a 10-year U.S. dollar obligation, so the currencies are matched. We are long U.S. dollars owned in the treasury, and we are short U.S. dollars in the funding of that, so the currencies are matched.
The interest rate exposure is matched, so movements in either exchange rates or interest rates have no net impact on the fiscal position of the Government of Canada. We do manage to earn a small positive return, because—happily—the interest rate we pay to fund these reserves is a little bit lower than the interest rate we receive on the assets.
