In the actuarial report prepared by the chief actuary, there is a sensitivity analysis. It shows the extent to which the contribution rate would vary if certain assumptions were different from the basic assumptions that were used. If fertility were lower than expected, if life expectancy were much longer, and if the economic assumptions, such as the interest rate, we used were wrong, it shows how sensitive it is, and so on.
So reading that sensitivity analysis in the report is quite instructive; it shows that the financing put in place is quite robust.
