That's a good question.
Over the last few years we've noticed a considerable reduction in the number of people applying for a refund. It's at the point now where we don't anticipate that all of the applicants will apply to have their refund. This entry in the main estimates reflects that fact. This is a statutory appropriation, and so anybody who does come in over the next few years will be eligible to receive their refund, and we will give it to them. This is just more of a forecast reflecting the fact that we don't anticipate in the near term requiring this amount of funding.
