Thanks very much for the question.
In terms of the statutory payments that are made each year to make sure the public service pension plan is financially sound, there are really two types of inputs that go in. They are what the employees contribute through their paycheques, and what the employer pays in terms of their fair share of the service costs to maintain the pension plan.
In addition to that, we get actuary reports every couple of years. According to section 6 of the Public Pensions Reporting Act, those actuarial reports have to come to us. Right now our pension plan, from a financial sustainability perspective, is in a bit of a deficit, and, over years, we have been paying these lump sum annual payments to the deficit.
The last actuarial report that was provided to us and was tabled in Parliament on January 25, 2016, actually said we've been doing well in paying down these actuarial deficits and they have actually reduced the amount we have to pay by $103 million a year.
That's the explanation.
