Neither reports, copies of documents obtained nor preliminary work and working papers may be disclosed without the prior written consent of the SPLRC. Such materials shall remain confidential and are not subject to subpoena. Nothing in this section shall prevent the director from using materials created during the examination or obtained during the examination in furtherance of the director’s regulatory authority granted under sections 379.1353 to 379.1421. The director may grant access to materials obtained or created during examinations conducted under this section to public officers having jurisdiction over the regulation of insurance in another state, the federal government or another country, including a securities regulatory authority, if the officers receiving the information agree in writing to hold such information in confidence and in a manner consistent with this section.
