Thank you very much for the question.
I think we have an extremely good handle on what we think the costs and the revenues will be on this. We've gone through it in a fairly rigorous way.
Why don't I provide you just a very brief explanation of what's involved in how we get these calculations? You'll see that it does kind of narrow the band of what types of revenue figures we're talking about.
I think that when we undertake the calculations, we basically divide this up into two groups. What is the primary interest of one group, that is, to get maternity and parental benefits? What is the primary interest of the second group to get sickness and compassionate benefits? As I said earlier, while a person is able to get the full suite of benefits, there is a primary interest.
So we start with that and we ask ourselves: how many people will want to sign up to get maternity and parental benefits? We have a very firm idea of that by looking at the QPIP experience, which is a mandatory system. When we look at the mandatory system, we look at how many claims were made. We go back to recent data for 2008 and we see that we have 7,300 people who made a claim.
Because it's a mandatory system, we know basically that all those who can claim will claim, because they have no incentive not to make the claim. They've already paid into the premiums.
From that, you can extrapolate fairly clearly what is the maximum amount of claims that could occur in the rest of Canada. So you take--
