What I could say is that typically, year over year, changes are somewhat unique. There are some common features. If collective agreements have provided for salary and wage increases, for example, those will be reflected. There will be, however, a lot of items, as we talked about, that are reflective of budgetary changes that new measures need to be provided for. That is a big determinant of the level of activity from one year to the next, and it would just depend on how much we've been impacted in those cases. Certainly, the changes this year and in the last couple of years have been heavily influenced by reduction measures--the expenditure review, procurement reform, and things of that nature--which, as I say, tend to dampen increases. It's very hard to generalize.
