(a) Every administrator shall maintain at its principal administrative office for the duration of the written agreement referred to in Section 1759.1 and five years thereafter adequate books and records of all transactions between it, and insurers and insured persons. The books and records shall be maintained in accordance with prudent standards of insurance recordkeeping. The insurer shall retain the right to continuing access to the books and records of the administrator sufficient to permit the insurer to fulfill all of its contractual obligations to insured persons, subject to any restrictions in the written agreement between the insurer and administrator on the proprietary rights of the parties in the books and records.

(b) The commissioner shall have access to the books and records for the purpose of examination, audit, and inspection. Any information contained in the books and records, including, but not limited to, the identity and addresses of policyholders and certificateholders, shall be confidential, except the commissioner may use the information in any proceedings instituted against the administrator.

(c) The commissioner may, after notice and hearing, promulgate reasonable rules and regulations specifying the manner and type of records to be maintained by administrators.

(d) Every administrator shall keep and maintain the books and records required by this section and the regulations promulgated pursuant to this section. Failure to keep or maintain the books and records as required shall be grounds for the suspension or revocation of the certificate of registration of the administrator. The proceeding shall be conducted in accordance with Chapter 5 (commencing with Section 11500) of Part 1 of Division 3 of Title 2 of the Government Code.
