Cal. Government Code § 63063

(a) There is a guarantee reserve account in the guarantee trust fund to secure commitments under contracts to guarantee all or part of the bonds of the bank, a special purpose trust, or of a sponsor, any contracts or obligations of the bank, a special purpose trust, or of a sponsor, and all or part of the accounts or subaccounts within the infrastructure bank fund. The bank shall take all reasonable steps to ensure that the guarantee reserve account is continuously maintained at not less than the reserve account requirement established pursuant to subdivision (a) of Section 63064. The bank shall pay all of the following into the guarantee reserve account: (1) Moneys appropriated and made available by the Legislature for deposit in the account. (2) Any proceeds of bonds, including general obligation bonds, to the extent provided in the resolution, trust agreement, resolutions or trust agreements authorizing the issue thereof. (3) Any other moneys that the bank may make available for the purpose of deposit to the guarantee reserve account. (b) The bank shall not cause sums to be withdrawn from the guarantee reserve account in amounts that would reduce the moneys therein to less than the reserve account requirement, except as necessary to satisfy liabilities arising under contracts of guarantee. In the event that the loan guarantee reserve account is reduced to less than the reserve account requirement, the bank shall cease making commitments for, and contracts of, guarantees and enhancements until the guarantee reserve account has been restored to that requirement.
