Cogent Statistical Services Computing Actuarial Skills:
There is little difference between pension actuarial and life insurance actuarial calculations. The primary difference is that pension plan actuarial calculations have more “exit points” (a.k.a. “turnover”) than life insurance actuarial calculations. The two components that they have in common is the mortality table and the interest rate assumption.
Both pension and life actuarial calculations involve the computation of single premium immediate rates and single premium deferred rates based upon the components of interest, mortality (death) and turnover (decrements).
Pension plan turnover consists of vested termination, non-vested termination, disability, early retirement and retirement. In simple life plans, turnover generally consists of lapse alone. Some life plans permit other types of turnover where the insurance benefit would not be paid.
