Cal. Food & Agric. Code § 55527.6

(a) Licensees or applicants for a license shall be required to furnish and maintain an irrevocable guarantee in a form and amount satisfactory to the secretary if, within the preceding four years, the secretary determines that they have done any of the following:
1. (1) Engaged in conduct which demonstrates a lack of financial responsibility, including, but not limited to, delinquent accounts payable, judgments of liability, insolvency, or bankruptcy.
2. (2) Failed to assure future financial responsibility unless an irrevocable guarantee is provided.
3. (3) Otherwise violated this chapter which resulted in license revocation.
(b) The irrevocable guarantee may include a personal or corporate guarantee, a certificate of deposit, a bank letter of credit, or a surety bond, as determined to be appropriate by the secretary.
(c) The guarantee shall not be less than ten thousand dollars ($10,000) or 20 percent of the annual dollar volume of business based on farm product value returned to the grower, whichever is greater, as assurance that the licensee’s or applicant’s business will be conducted in accordance with this chapter and that the licensee or applicant will pay all amounts due farm products creditors.
(d) The secretary, based on changes in the nature and volume of business conducted by the licensee, may require an increase or authorize a reduction in the amount of the guarantee, but in no case shall the guarantee be reduced below ten thousand dollars ($10,000). A licensee who is notified by the secretary to provide a guarantee in an increased amount shall do so within a reasonable time as specified by the secretary. If the licensee fails to do so, the secretary may, after a notice and opportunity for a hearing, suspend or revoke the license of the licensee.
