Will accumulating a dedicated pool of assets reduce the GASB liability?
Accumulating assets in certain trusts or funds will help reduce the GASB liabilities
in two ways.
Dedicated assets will reduce the unfunded liabilities and ongoing annual expense.
For example, a plan with $10,000,000 in liabilities and $0 assets will have a higher
annual expense than a plan with $10,000,000 in liabilities and $4,000,000 in accumulated
assets.
Having dedicated assets will allow the actuary to use a higher interest discount
assumption than otherwise would have been possible. The interest discount is one
of the key assumptions used in the healthcare actuarial projections. Per GASB requirements,
this assumption must be based on the underlying investment return of assets used
to finance the retiree health benefits. Employers that pay benefits using general
account assets, which typically are restricted to very secure low-return investments,
will earn a return in the range of 1.5% to 3%. The low return will then translate
to a low interest discount assumption. Accumulated assets in certain trusts are
able to earn much higher investment returns and, therefore, will have a higher interest
discount assumption. Below is a table quantifying the effect on liabilities from
using different interest discount assumptions.
