This is a very generic way just to kind of stress test the financial statements. Obviously, if the economy grows or contracts, that's going to have direct impacts on tax collection and consumption, feeding through to personal and corporate income taxes, GST and other excise taxes. As inflation goes up or down, it feeds through to one side of the income statement, whether it be inflation-adjusted benefits...or a different side of the income statement, whether it be public debt charges and, as you talked about, interest rates feeding through into higher debt charges....
Therefore, this was just a very generic way to demonstrate that in the public accounts. We do a more comprehensive type of sensitivity analysis in our budget and fall update, but it's the same sort of thing.
