In order to effectively meet the cyclical cash flow needs of the insurance regulatory trust fund, the office of management and budget upon approval of the emergency commission is hereby authorized to issue certificates in anticipation of revenue, notes, or bonds, to funds on deposit in the state treasury. Any issue of such certificates, notes, or bonds must be approved by the emergency commission and are to be used for cash flow financing only and not to offset projected deficits in the insurance regulatory trust fund. The terms of any specific issue of such certificates, notes, or bonds may not exceed one hundred eighty days from the date of issuance whereupon the principal and interest on the certificates, notes, or bonds must be paid in full from the insurance regulatory trust fund or from another issue of a similar nature. All principal and interest on such issues made during a biennial period must be repaid in full at the close of     the biennial period from the insurance regulatory trust fund. When certificates, notes, or bonds are issued for cash flow purposes to funds which otherwise would be invested, with the investment income accruing to the fund, the certificate shall bear an investment rate of return which must be agreed upon by the state investment board and must be at a level commensurate with the yield to be reasonably expected by such fund if invested in alternate securities.
