California Code, Insurance Code - INS § 730

(a) The commissioner, whenever he or she deems necessary or whenever he or she is requested by verified petition, signed by 25 persons interested as shareholders, policyholders, or creditors of any admitted insurer showing that the insurer is insolvent under this code, or upon information that any insurer has violated any provision of Article 7 (commencing with Section 800), shall examine the business and affairs of the insurer. The commissioner shall so examine every domestic insurer before issuing to it a certificate of authority other than a renewal.

(b) The commissioner may conduct an examination under this article of any company as often as the commissioner in his or her discretion deems appropriate but shall, at a minimum, conduct an examination of every insurer admitted in this state not less frequently than once every five years. In scheduling and determining the nature, scope, and frequency of the examinations, the commissioner shall consider the results of financial statement analyses and ratios, changes in management or ownership, actuarial opinions, reports of independent certified public accountants, market analysis results, including consumer complaint analysis, evaluation of ongoing regulatory activities, analysis of data derived from industry surveys or interrogatories, and other criteria as set forth in the Examiner's Handbook or in the Market Regulation Handbook adopted by the National Association of Insurance Commissioners that are in effect when the commissioner exercises discretion under this section.

(d) In lieu of an examination under this article of any foreign or alien insurer admitted in this state, the commissioner may accept an examination report on the company as prepared by the insurance department of the company's state of domicile or port-of-entry state until January 1, 1994. Thereafter, these reports may only be accepted if (1) the insurance department was at the time of the examination accredited under the National Association of Insurance Commissioner's Financial Regulation Standards and Accreditation Program, or (2) the examination is performed under the supervision of an accredited insurance department or with the participation of one or more examiners who are employed by an accredited state insurance department and who, after a review of the examination work papers and report, state under oath that the examination was performed in a manner consistent with the standards and procedures required by their insurance department.
