The state treasurer shall direct the investment of the MPSERS retirement obligation reform reserve fund. The state treasurer shall credit to the MPSERS retirement obligation reform reserve fund interest and earnings from the MPSERS retirement obligation reform reserve fund. (3) Money available in the MPSERS retirement obligation reform reserve fund must not be expended without a specific appropriation. (4) Money in the MPSERS retirement obligation reform reserve fund at the close of the fiscal year remains in the MPSERS retirement obligation reform reserve fund and does not lapse to the state school aid fund or to the general fund.
