(a) Each member may elect to reduce his compensation by the amount of his contribution to the Supplemental Retirement Income Plan and that amount shall be held in the member's account. Members electing such a reduction in compensation may authorize payroll deductions for making contributions to the Plan.
(b) The State and any of its political subdivisions may make contributions to the Supplemental Retirement Income Plan on behalf of any of its members, provided these contributions are nondiscriminatory in accordance with the Internal Revenue Code of 1954 as amended, and are duly appropriated by their governing bodies, and the contributions are held in the member's account. Employer contributions to the Plan are declared expenditures for a public purpose.
(c) The Department of State Treasurer and Board of Trustees shall establish maximum annual additions that may be made to a member's account and provide for multiple plan reductions in accordance with the Internal Revenue Code of 1954 as amended. (1983 (Reg. Sess., 1984), c. 975.)
