(a) It is intended that the provisions of this subtitle be construed and administered in a manner that the retirement system’s benefit plan will be considered a qualified plan under Section 401(a) of the Internal Revenue Code of 1986 (26 U.S.C. § 401). Notwithstanding any other provision of this subtitle, benefits provided to a retiree, or based on the service of a member or retiree, may not exceed benefits permitted to be provided by a qualified plan by Section 415 of the Internal Revenue Code of 1986 (26 U.S.C. § 415). The board of trustees may adopt rules that modify the plan to the extent necessary for the retirement system to be a qualified plan and shall adopt rules to ensure that benefits paid to a retiree, or to a beneficiary of a member or retiree, do not exceed the limits provided by Section 415 of the Internal Revenue Code of 1986 (26 U.S.C. § 415). Rules adopted by the board of trustees are to be considered a part of the plan.
(b) In determining qualification status under Section 401(a) of the Internal Revenue Code of 1986 (26 U.S.C. § 401), the retirement system’s benefit plan shall be considered primary. An employer may not provide employee retirement or deferred benefits to the extent that, when considered together with the benefits authorized by this subtitle as required by federal law, would result in the retirement system’s plan failing to meet federal qualification standards as applied to public pension plans.

(c) It is intended that the retirement system administer the plan in a manner that satisfies the required minimum distribution provisions of Section 401(a)(9), Internal Revenue Code of 1986. The board of trustees may adopt rules to administer the distribution requirements, including distribution when a participant dies before the entire interest is distributed.
