There are standards for accounting for pension liabilities. There are an enormous number of estimates, and you would have to make estimates based on actuarial assumptions. There's a large body of literature out there already.
Truthfully pension accounting, as complicated as it can seem to non-accountants, is fairly well established in accounting literature and, in terms of accrual accounting, it's fairly well accepted in terms of developing the obligation for pension liability.
I would agree with you. If you make a change in a decision that would result in an increase in the pension obligation, what you will have to pay down the road, then it would be reflected in the government's balance sheet, and I would suggest it should be reflected in the balance sheet. The importance of having that information is to make better decisions. That decision have did an impact. It is an impact that reflected the increased liabilities of the government and the importance of that.
There are a lot of technicalities in pension accounting, but it's fairly well laid out in both private sectors, business accounting, and in public sector accounting.
