Your state's promised pension payments amount to $10 billion annually, and you expect this obligation to grow at 2% per year. You determine that the riskiness of this obligation is the same as the riskiness of the state's debt.

Currently, based on actuarial calculations using 8% as the discount rate, the plan is niether over- nor underfunded - the value of the liabailities exactly matches the value of the assets. What is the extent of the true unfunded liabilities?
