The California Insurance Code was recently modified to increase financial data protection for insurers. Under the Code, all insurers authorized to do business in California must file a registration  statement containing specified financial information, including the capital structure and general financial condition of the insurer. Under the modified law, such information, whether reported in the registration statement or disclosed in the course of an examination or investigation of the registration statement, is exempt from public disclosure by the state Insurance Commissioner and not subject to discovery from the Commissioner or admissible into evidence in any private civil action, except as specified.
