Cal. Government Code § 63062

(a) The bank may, from time to time, direct the Treasurer to invest moneys in the guarantee trust fund that are not required for its current needs in any eligible securities specified in Section 16430 that the bank shall designate. The bank 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 bank may direct the Treasurer to invest the moneys in the subordinated securities of the bank, a special purpose trust, or a sponsor. The bank may direct the Treasurer to invest the moneys in investment agreements with corporations, financial institutions, or national associations within the United States that are rated by a nationally recognized rating service within the top three rating categories of the service. For purposes of this section, investment agreements shall mean any agreement for the investment of moneys in the guarantee trust fund whether at fixed or variable interest rates, and may include, but not be limited to, repurchase agreements, notes, uncollateralized time deposits, certificates of deposit, and the subordinated securities of the bank, a special purpose trust, or a sponsor. The bank 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. (b) In furtherance of Section 51373 of the Health and Safety Code, and to the extent permitted by law, the bank may also invest moneys of the guarantee trust fund in obligations of financial institutions that are permitted by board resolution. The bank may alternatively require the transfer of moneys in the guarantee trust 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. (c) All interest or other increment resulting from the investment or deposit shall be deposited in the guarantee trust fund, notwithstanding Section 16305.7. (d) The bank may create other accounts within the guarantee trust fund as are necessary or convenient to carry out the purposes of this article.
