I will give you a bit of a comparison with the OECD countries. There are mainly three ways to recognize the pension promise or the liabilities related to public servants. First, in Mexico, for example, you pay the retirees and you don't necessarily book the liabilities before, when the service is rendered. Second, there's what we call notional funding, which is what we had in Canada before 2000. There were credits representing employee and employer contributions that went into the superannuation account through the Consolidated Revenue Fund. The third way is to back the liabilities by tangible assets, which is what has been done since 2000.
One thing particular to our plan is that when you start to finance years of service starting in 2000, 2001, and 2002, it means that the minute before, 100% of your liabilities are on the government books. As time passes, this liability is transferred and backed by tangible assets. As we speak today, 13 years after the implementation started on April 1, 2000, when we look at the total liabilities, about 30% for the public service is backed by tangible assets, and the remaining 70% for service before the year 2000 is still on the government books.
Going forward to 2050, because it takes that long to move the liabilities, because the pension plan is of a long-term nature, by 2050 almost all of the pension promise will be backed by tangible assets.
