Health & Saf. Code, § 51003

The agency shall, from time to time, direct the Treasurer to invest moneys in the fund which are not required for its current needs, including proceeds from the sale of any bonds, in any eligible securities specified in Section 16430 of the Government Code which the agency shall designate. The agency may direct the Treasurer to invest the moneys by entering into repurchase agreements or reverse repurchase agreements, which, for purposes of this section, shall mean agreements for the purchase or sale of eligible securities pursuant to which the seller or buyer agrees to repurchase or sell back the securities on or before a specified date and for a specified amount. The agency may direct the Treasurer to invest the moneys in investment agreements with corporations, financial institutions, or national associations within the United States which are rated by a nationally recognized rating service within the top three ratings of the service. For purposes of this section, investment agreements shall mean any agreement for the investment of moneys in the fund whether at fixed or variable interest rates, and may include, but not be limited to, repurchase agreements, notes, uncollateralized time deposits and certificates of deposit. The agency may direct the Treasurer to deposit moneys in interest-bearing accounts in state or national banks or other financial institutions having principal offices in this state.

Subject to any agreement with holders of particular bonds, in furtherance of the provisions of Section 51373, and to the extent permitted by law, the agency may also invest moneys of the fund in obligations or financial institutions as are permitted by board resolution. The agency may alternatively require the transfer of moneys in the fund to the Surplus Money Investment Fund for investment pursuant to Article 4 (commencing with Section 16470) of Chapter 3 of Part 2 of Division 4 of Title 2 of the Government Code.

All interest or other increment resulting from such investment or deposit shall be deposited in the fund, notwithstanding Section 16305.7 of the Government Code. Moneys in the fund shall not be subject to transfer to any other fund pursuant to any provision of Part 2 (commencing with Section 16300) of Division 4 of Title 2 of the Government Code, excepting the Surplus Money Investment Fund.
