Sure, I can add a little to that.
When you're looking at international comparisons of net debt positions, clearly for Canada there are two main factors for which we have to make adjustment. The first is the federal nature of Canada and the second is the fact that we, unlike many other countries, have a large contributory public pension plan, the CPP and the QPP, so the number that you have here for Canada in the total government net debt comparator is the sum of the debts of the federal government and the provincial governments, less the assets in those two pension plans.
