CA Ins Code Section 1063.64

The department and CIGA are each authorized to enter into those contracts or agreements with those banks, insurers, or other financial institutions that it determines are necessary or desirable to improve the security and marketability of the bonds issued under this article. Those contracts or agreements may contain an obligation to reimburse, with interest, any of those banks, insurers, or other financial institutions for advances used to pay the purchase price of, or principal or interest on, the bonds. Any such reimbursement obligation shall be payable solely from, and may be secured by a pledge of, the revenues derived from the insurance assessments levied for that purpose or from loan repayments by CIGA.
