I don't have any statistics in terms of the number of overpayments or the number of people who have overpayments in the system.
I may have said on previous occasions that there are a number of circumstances that could lead to a situation of overpayment. To be clearer, and just to expand on that example, if you have a person who is married and who suddenly gets divorced but doesn't come to the department to let us know that, you might be in a situation of recovery of an overpayment. Or the opposite may hold true because you've paid the guaranteed income supplement on different income levels and different marital status; you could find yourself in a situation where the individual hasn't come forward to let us know.
For the most part, they do let us know, but there are situations where they do not, and they won't tell us, let's say, for a number of years. People can find themselves in a situation where the recovery of the overpayment would have taken place over a number of years. You have to recover that overpayment, and it might be big. With a time limitation of six years, you have a short period of time in which to recover that overpayment.
