Sec. 14. INTERNAL REVENUE CODE LIMITATIONS. (a) Notwithstanding any other provision of this article, a member may not accrue a benefit or allowance under this article in excess of an amount that, when added to all other pension benefits received under plans of the municipality that are qualified under Section 401 of the code, results in an annual benefit in excess of the applicable limits provided by Section 415 of the code. That accrual limitation applies only as long as satisfaction of Section 415 of the code is necessary to maintain the tax-qualified status of the fund under Section 401 of the code. Any benefit accruals limited under this subsection must be determined by a qualified actuary selected by the board.

(b) Notwithstanding any other provision of this article, the fund shall be administered in a manner that complies with the code, United States Treasury Department regulations, and Internal Revenue Service rulings and notices applicable to public retirement systems. The board shall adopt rules and amend or repeal conflicting rules to ensure compliance with this subsection.

(c) The board may establish and maintain a qualified governmental excess benefit arrangement, in accordance with Section 415(m) of the code, solely for the purpose of providing to members the amount of each member's pension benefit otherwise payable under the fund that exceeds the limitations on benefits imposed by Section 415 of the code. The board may maintain a separate trust solely for providing benefits under the arrangement or may maintain the arrangement on an unfunded basis through municipal contributions as benefits become payable. Benefits provided by that arrangement may not be paid from the trust fund assets that are available for payment of any other benefit under this article. Benefits under any qualified governmental excess benefit arrangement shall be paid or funded entirely through municipal contributions in an amount approved by the board. An election may not be provided at any time to a member, directly or indirectly, to defer compensation under the arrangement. The operation and administration of any qualified governmental excess benefit arrangement is the responsibility of the board, which has the same powers concerning the arrangement as are provided to the board under this article concerning the fund.
