(1) The purpose of this chapter is to provide pension benefits for the exclusive benefit of the member employees or their beneficiaries.
(2) No part of the principal or income of the trust fund created hereunder shall be used or diverted for purposes other than for the exclusive benefit of the member employees or their beneficiaries and for the payment of administrative cost.

(5) No benefit payable hereunder for any limitation year shall exceed the maximum amount, including cost-of-living adjustments, allowable by law for qualified pension plans under applicable provisions of the Internal Revenue Code of the United States. In the event of any participation of a Florida Retirement System member in any other plan that is maintained by the participating employer, benefits that accrue under the Florida Retirement System shall be considered primary for any aggregate limitation applicable under s. 415 of the Internal Revenue Code.

This limitation, which has been part of the Florida Retirement System since plan years beginning on or after July 1, 1990, shall be adjusted as required by federal law for qualified government plans.
