I think it's important to understand that because this program is voluntary, we can only have estimates of what we expect the take-up to be, what we expect claimant rates to be, and what we expect the duration of claims to be. One of the things that will be going on is that we will be tracking this very closely, because we want to see what the actual numbers are going to turn out to be.
Our estimate is that this program is going to be essentially self-financing, but obviously if there is a higher participation rate that means more revenues. If there's a lower claim on benefits, whether it's in frequency, or indeed in duration, because quite often the self-employed feel that they can't stay away from work for a full 50 weeks for maternity or parental leave, then obviously that will have an impact on the net cost.
That being said, we have included a proposal to review the program at five years.
