Insider communication restrictions: limits on sharing unpublished price sensitive information, requiring confidentiality and internal databases to track access. Restrictions prohibit insiders from communicating or allowing access to unpublished price sensitive information except for legitimate purposes, performance of duties, or discharge of legal obligations; recipients for legitimate purposes are treated as insiders and must be bound by confidentiality. Boards of asset management companies must define legitimate purposes, require confidentiality agreements, and ensure maintenance of an internal structured digital database recording information shared, participants, identifiers, time stamps and audit trails, with mandated preservation during investigations and for a minimum post transaction period.
