Cal. INS § 925

Upon request of the commissioner, and at intervals as prescribed by him or her, any insurer that appears to the commissioner to require immediate regulatory attention shall provide to the commissioner supplemental accounting, financial, and actuarial information. The commissioner may request that an insurer select and retain an independent certified public accountant, certified public accountant corporation, an actuary corporation, or an independent actuary satisfactory to the commissioner, if that person has not already been retained by the insurer, whenever the information supplied or likely to be supplied is not satisfactory or acceptable to the commissioner, or, whenever the person who would be responsible for that preparation of that information has previously provided information that was not satisfactory or acceptable to the commissioner. The commissioner may select or retain an independent certified public accountant, a certified public accountant corporation, an actuary corporation, or an independent actuary, if the insurer does not within a reasonable time make the selection as requested by the commissioner. If the information is prepared by an independent certified public accountant or independent actuary, or other independent professional financial corporation or person, the corporation or person shall examine and render an opinion upon that supplemental information.
