Description: Issued in 2004 with provisions effective in 2006-2009, the United States accounting standard, GASB 45, requires local and state governments to account for their post-retirement medical and life insurance programs on an accrual basis for the first time. This standard is creating new demands for actuarial services.

For these actuaries, there are many similarities between a FAS 106 valuation and a GASB 45 valuation, but there are also many differences.
