Well, thank you for the question.
It's not something that we perform, a detailed analysis audit, if you will, of federal fiscal projections. The federal government uses external forecasters for the fundamental inputs for that analysis, as you know, and it uses the average of those external forecasters.
I will only hypothesize that the adjustment in the debt charges is importantly affected by the level of interest rates. Obviously, the debt charges are the product of the interest rates, long-term and short-term interest rates, duration weighted, and the level of public debt.
There has been an important reduction in the level of global and Canadian long-term interest rates in between the spring and the fall, given the global outlook. That adjustment, I presume, has extended over the forecast horizon for private sector forecasters, but it's to them and to the federal finance department that the question is best directed.
