Twice the employee required contributions, after first subtracting the accumulations under subd. 2., including interest on the accumulations. Except, for a county jailer described in s. 40.02 (48) (am) 23., the amount equal to the employee required contributions and the employer required contributions paid for a county jailer under s. 40.05 (2) (a), after first subtracting the accumulations under subd. 2., including interest on the accumulations. The amount applicable for a county jailer applies only to a county jailer who becomes a protective occupation participant on or after January 1, 2024, and who is one of the following: a. Employed in a county that did not classify county jailers as protective occupation participants on January 1, 2024.b.

If there is more than one beneficiary the amount of the annuity and its present value will be determined as if the oldest of the beneficiaries were the sole beneficiary. If the death benefit payable to the beneficiary under this paragraph would be less than the amount determined under par. (am) the death benefit shall be payable under par. (am) and this paragraph shall not be applicable to the beneficiary. An annuitant receiving an annuity only under s. 40.24 (1) (f), which annuity was an immediate annuity, shall be deemed a participating employee for purposes of this paragraph only, but the amount payable under s. 40.24 (1) (f) shall not be changed.(d) Increased, upon the death of a participant who had elected the additional benefit provided by s. 42.81 (14), 1979 stats., and continued making the contributions provided for in s. 42.81 (14), 1979 stats., and was eligible for the benefit on December 15, 1988, by an amount and for a period determined by the actuary and approved by the board as being appropriate to the level of contributions provided for in s. 42.81 (14), 1979 stats., or any lower level of contributions, as determined by the actuary and approved by the board.

(a), the then present value of the annuity shall be paid as a death benefit under sub. (1) if:1. The estate of the annuitant is the beneficiary;2. No beneficiary of the annuitant survives;3. The death of the beneficiary occurs after having become entitled to receive payments under par. (a), but prior to the end of the period guaranteed;4. The amount of the monthly payments to the beneficiary, including any amount payable under s. 40.27, is less than the amount determined under s. 40.25 (1) (a); or5.

The number of guaranteed monthly payments available to a beneficiary may not exceed the life expectancy of the beneficiary.(f) Any beneficiary between ages 18 and 21 or the legal or natural guardian of a minor beneficiary may, in lieu of a life annuity, elect that the death benefit be paid in the form of a temporary life annuity, beginning on the day following the date of death of the participant or annuitant and ending with the monthly payment immediately prior to the beneficiary's 21st birthday, and a final payment, payable one month after the termination of the temporary annuity, in the amounts specified in the application, provided the amounts can be provided from the death benefit, on the basis of the actuarial tables in effect on the date of initial approval of the annuity. A beneficiary, prior to the final payment, may, if the amount of the final payment is sufficient to provide an immediate beneficiary annuity in the normal form of at least an amount equal to the amount determined under s. 40.25 (1) (a) monthly, elect to receive in lieu of the final payment an annuity commencing on the day following the date of termination of the temporary annuity, determined on the basis of the actuarial tables in effect on the date of initial approval of the annuity.Amended by Acts 2023 ch, 4,s 17r, eff. 1/1/2024.Amended by Acts 2023 ch, 4,s 17g, eff. 1/1/2024.Amended by Acts 2013 ch, 20,s 754m, eff. 7/2/2013.1981 c. 96; 1983 a. 141, 290; 1987 a. 309; 1989 a. 110, 166; 1995 a. 302, 414; 1997 a. 58; 1999 a. 11, 12; 2005 a. 154; 2007 a. 96, 131. Whatever effect the Marital Property Act, ch. 766, may have with respect to property rights between spouses, it has no effect on the Board's determination of a beneficiary under ch. 40. Jackson v. Employee Trust Funds Board, 230 Wis. 2d 677, 602 N.W.2d 543 (Ct. App. 1999), 98-3063. The board's consistent interpretation of "Mr. & Mrs." beneficiary designations as relating to the identity of the beneficiaries on the date of the designation. was reasonable. Jackson v. Employee Trust Funds Board, 230 Wis. 2d 677, 602 N.W.2d 543 (Ct. App. 1999), 98-3063. Nothing in s. 40.73 creates an entitlement in the beneficiary to the annuity-value single cash sum benefit as of the date of death even though the value of the single cash sum benefit is calculated as of the date of death. A beneficiary does not acquire a property interest in a single cash sum death benefit under sub. (1) (c) until the beneficiary applies for a death benefit as required by s. 40.71(3). Fazio v. Department of Employee Trust Funds, 2006 WI 7, 287 Wis. 2d 106, 708 N.W.2d 326, 04-0064.
