That's right. In my previous testimony, Mr. Chair, I spoke to the number of regret letters that are sent. I quoted a figure of just over 4,300. Those letters are sent to members when there is a difference between the payment we make to the member and the amount that was claimed. Out of that high number of regret letters, as I indicated, on average over the last two years, only seven requests have gone to the board for reconsideration. I can tell you that in all but one instance the previous decision made by the administration was held, so if you look at fourteen instances over two years, if you want to use averages, in one instance the decision of the board was different from the decision of the administration, so I think we're doing our job in terms of adjudicating claims according to the rules we have in place. Those rules do require receipts for all but a few items.
It's the same thing in government. To claim a per diem expense, you don't need a receipt, because you don't get a receipt for a per diem. It's an allowance paid in lieu of supplying receipts for meals. It's the same thing with mileage. If you drive so many kilometres, you're reimbursed for kilometres. We require a road travel log in which members complete the purpose of their travel, where they're going from and to, and the kilometrage claimed. When we get that claim, we verify with Google Maps to see whether that's reasonable. If it's reasonable, we pay the claim. If it's not, then we send a regret letter and we're back into that whole process again.
Clearly, we're inspired by what happens in government in terms of the regimes it has with respect to expenditures. The per diem we use is the one used in government. It's set by Treasury Board. The BOIE doesn't set that per diem. The kilometrage rate is also set by Treasury Board. We use that particular item as well.
