Section 5. (a) Documents, materials or other information including the CGAD, in the possession or control of the division that are obtained by, created by or disclosed to the commissioner or any other person under this chapter shall be proprietary and recognized to contain trade secrets. All such documents, materials or other information shall be confidential by law and privileged, shall not be considered a public record pursuant to section 10 of chapter 66, shall not be subject to subpoena and shall not be subject to discovery or admissible in evidence in any private civil action. However, the commissioner may use the documents, materials or other information in the furtherance of any regulatory or legal action brought as a part of the commissioner's official duties. The commissioner shall not otherwise make the documents, materials or other information public without the prior written consent of the insurer. Nothing in this section shall require written consent of the insurer before the commissioner may share or receive confidential documents, materials or other CGAD-related information pursuant to subsection (c) to assist in the performance of the commissioner's regular duties.

(b) Neither the commissioner nor any person who received documents, materials or other CGAD-related information, through examination or otherwise, while acting under the authority of the commissioner, or with whom such documents, materials or other information are shared pursuant to this chapter shall be permitted or required to testify in any private civil action concerning any confidential documents, materials or information subject to subsection (a).

(c) In order to assist in the performance of the commissioner's regulatory duties, the commissioner may:

(i) upon request, share documents, materials or other CGAD-related information including the confidential and privileged documents, materials or information subject to subsection (a), including proprietary and trade secret documents and materials with other state, federal and international financial regulatory agencies, including members of any supervisory college as defined in subsection (x) of section 206C of chapter 175, with the NAIC, and with third party consultants pursuant to section 6, provided that the recipient agrees in writing to maintain the confidentiality and privileged status of the CGAD-related documents, material or other information and has verified in writing the legal authority to maintain confidentiality; and

(ii) receive documents, materials or other CGAD-related information, including otherwise confidential and privileged documents, materials or information, including proprietary and trade-secret information or documents, from regulatory officials of other state, federal and international financial regulatory agencies, including members of any supervisory college as defined in said subsection (x) of said section 206C of said chapter 175, and from the NAIC, and shall maintain as confidential or privileged any documents, materials or information received with notice or the understanding that it is confidential or privileged under the laws of the jurisdiction that is the source of the document, material or information.

(d) The sharing of information and documents by the commissioner pursuant to this chapter shall not constitute a delegation of regulatory authority or rulemaking, and the commissioner is solely responsible for the administration, execution and enforcement of the provisions of this chapter.

(e) No waiver of any applicable privilege or claim of confidentiality in the documents, proprietary and trade-secret materials or other CGAD-related information shall occur as a result of disclosure of such CGAD-related information or documents to the commissioner under this section or as a result of sharing as authorized in this chapter.
