If we are talking about the way that we evaluate our risks and the actuarial impact on the funds, I would say that this work is done by the Chief Actuary. He works closely with us over each three-year valuation period.
As for the question on the period before 2000, when we did not have a fund as we did for the period after 2000, my colleague from the Department of Finance would best be able to speak to the government's approach.
However, I can guarantee that a very detailed evaluation of actuarial risks is undertaken by my colleague, the Chief Actuary, who might have a little bit more to tell you.
