Investment managers shall be limited to authorized insurers as defined in s. 624.09, banks as defined in s. 658.12, associations as defined in s. 665.012, authorized Securities and Exchange Commission investment advisers, and investment companies as defined in the Investment Company Act of 1940. All investment managers shall have their principal place of business and corporate charter located and registered in the United States. In addition, each investment manager shall agree to meet the obligations of the board to qualified beneficiaries if moneys in the fund fail to offset the obligations of the board as a result of imprudent investing by such provider. Each authorized insurer shall evidence superior performance overall on an acceptable level of surety in meeting its obligations to its policyholders and other contractual obligations. Only qualified public depositories approved by the Chief Financial Officer shall be eligible for board consideration. Each investment company shall provide investment plans as specified within the request for proposals. The goals of the board in procuring such services shall be to provide all purchasers and benefactors with the most secure, well-diversified, and beneficially administered prepaid program or savings program possible, to allow all qualified firms interested in providing such services equal consideration, and to provide such services to the state at no cost and to the purchasers and benefactors at the lowest cost possible. Evaluations of proposals submitted pursuant to this subsection shall include, but not be limited to, fees and other costs that are charged to purchasers or benefactors that affect account values, or that impact the operational costs of the prepaid program or the savings program; past experience and past performance in providing the required services; financial history and current financial strength and capital adequacy to provide the required services; and capabilities and experience of the proposed personnel that will provide the required services.
