Sec. 24. EXCESS BENEFIT PLAN. (a) A separate, nonqualified, unfunded excess benefit plan is reenacted and continued outside the pension fund.

(b) In this section:

(1) "Excess benefit participant" means any retiree whose retirement benefits, as determined on the basis of all qualified plans without regard to the limitations provided by Section 23 of this Act and comparable provisions of other qualified plans, would exceed the maximum benefit permitted under Section 415, Internal Revenue Code of 1986, as amended.

(2) "Excess benefit plan" means the separate, nonqualified, unfunded excess benefit plan that is continued under this section, that was created under the predecessor system for the benefit of eligible members, as amended or restated from time to time, and that is intended to be a qualified governmental excess benefit arrangement within the meaning of Section 415(m), Internal Revenue Code of 1986, as amended.

(3) "Maximum benefit" means the retirement benefit a retiree and the surviving spouse or dependent child of a retiree or deceased member or retiree are eligible to receive from all qualified plans in any month after giving effect to Section 23 of this Act and any similar provision of any other qualified plan designed to conform to Section 415, Internal Revenue Code of 1986, as amended.

(4) "Qualified plan" means the fund and any other plan that is maintained by the city for the exclusive benefit of some or all of the members of the fund and that has been found by the Internal Revenue Service to be qualified or has been treated by the city as a qualified plan under Section 401, Internal Revenue Code of 1986, as amended.

(5) "Unrestricted benefit" means the monthly retirement benefit a retiree and the surviving spouse and dependent child of a retiree or deceased member or retiree would have received under the terms of all qualified plans, except for the limitations provided by Section 23 of this Act and any similar provision of any other qualified plan designed to conform to Section 415, Internal Revenue Code of 1986, as amended.

(c) An excess benefit participant who is receiving benefits from the pension fund is eligible for a monthly benefit under the excess benefit plan in an amount equal to the lesser of:

(1) the member's unrestricted benefit less the maximum benefit; or

(2) the amount by which the member's monthly benefit from the pension fund has been reduced because of the limitations provided by Section 415, Internal Revenue Code of 1986, as amended.

(d) If a surviving spouse or dependent child is eligible for preretirement or postretirement survivor benefits under a qualified plan after the date of the death of an excess benefit participant, the surviving spouse or dependent child is eligible for a monthly benefit under the excess benefit plan equal to the benefit determined in accordance with this Act, without regard to the limitations provided by Section 23 of this Act or Section 415, Internal Revenue Code of 1986, as amended, less the maximum benefit.

(e) Any benefit to which a person is eligible under this section shall be paid at the same time and in the same manner as the benefit that would have been paid from the pension fund if payment of the benefit from the pension fund had not been precluded by Section 23 of this Act. An excess benefit participant or a beneficiary of the participant may not, under any circumstances, elect to defer receipt of all or any part of a payment due under this section.

(f) The pension board shall administer the excess benefit plan, and the executive director shall carry out the business of the board with respect to the plan. Except as otherwise provided by this section, the rights, duties, and responsibilities of the pension board and the executive director are the same for the plan as for the pension fund.

(g) The consultants, independent auditors, attorneys, and actuaries selected to perform services for the pension fund shall perform services for the excess benefit plan, but their fees for services may not be paid by the pension fund. The actuary engaged to perform services for the pension fund shall advise the pension board of the amount of benefits that may not be provided from the pension fund solely by reason of the limitations provided by Section 415, Internal Revenue Code of 1986, as amended, and of the amount of employer contributions that will be made to the plan rather than to the pension fund.

(h) Contributions may not accumulate under the excess benefit plan to pay future retirement benefits. The executive director shall reduce each payment of employer contributions that would otherwise be made to the pension fund under Section 8A of this Act by the amount determined to be necessary to meet the requirements for retirement benefits under the plan, including reasonable administrative expenses, until the next payment of municipal contributions is expected to be made to the pension fund. The employer shall pay to the plan, from the withheld contributions, not earlier than the 30th day before the date each distribution of monthly retirement benefits is required to be made from the plan, the amount necessary to satisfy the obligation to pay monthly retirement benefits from the plan. The executive director shall satisfy the obligation of the plan to pay retirement benefits from the employer contributions transferred for that month.

(i) Employer contributions otherwise required to be made to the pension fund under Section 8A of this Act and to any other qualified plan shall be divided into those contributions required to pay retirement benefits under this section and those contributions paid into and accumulated to pay the maximum benefits required under the qualified plan. Employer contributions made to provide retirement benefits under this section may not be commingled with the money of the pension fund or any other qualified plan.

(j) Benefits under this section are exempt from execution, attachment, garnishment, assignment, injunction, and any other writ in the same manner as retirement annuities under Section 22 of this Act and may not be paid to a person other than to the person who would have received the benefits from the pension fund except for the limitations provided by Section 23 of this Act.
