The Full Formula benefit calculation is increased or decreased based on the value of the
variable contributions being higher or lower than the value of the same contributions had they
been in the regular account. The increase or decrease is calculated by comparing your variable
account balance at your effective retirement date with the amount your variable contributions
would have been worth if they had been in the regular account.
The difference between your contributions at the variable rate amount (Var-Var) and your
contributions at the regular rate amount (Var-Reg) is multiplied by an annuity factor based on
your age at retirement. The result is added to or subtracted from the Refund Annuity (RA)
option benefit that the Full Formula calculation method produces. The adjustment will result
in a reduction if the contributions at the variable rate earned less than the contributions
would have earned at the regular rate.
