40.28 Variable benefits.
(1) Any annuity provided to a participant whose accounts include credits segregated for a variable annuity shall consist of a core annuity and a variable annuity.
(a) The initial amount of the variable annuity shall be the amount which can be provided on the basis of the actuarial tables in effect on the effective date of the annuity by the following amounts, if otherwise available:
1. The amount of the additional contribution accumulations reserved for a variable annuity as of the date the annuity begins;
2. The amount equal to 200 percent of employee required contribution accumulations reserved for a variable annuity as of the date the annuity begins; and
3. The amount equal, as of the date the annuity begins, to the accumulated prior service credits reserved for the participant for a variable annuity within the employer accumulation account, together with the net gain or loss credited to the accumulations.
(b) The initial amount of the core annuity shall be the excess of the total annuity payable, as determined under s. 40.23, over the amount of the variable annuity.
(2) Whenever the balance in the variable annuity reserve, as of December 31 of any year, exceeds or is less than the then present value of all variable annuities in force, determined in accordance with the rate of interest and approved actuarial tables then in effect, by at least 2 percent of the present value of all variable annuities in force, the amount of each variable annuity payment shall be proportionately increased or decreased, disregarding fractional percentages, and effective on a date determined by rule, so as to reduce the variance between the balance of the variable annuity reserve and the present value of variable annuities to less than one percent.
(3) Except as otherwise specifically provided, benefits based on variable accumulations shall be determined on the same basis and paid in the same manner and at the same time as benefits based on accumulations not so segregated insofar as practicable considering the nature of variable annuities.
