Restriction on association with unregistered advisers limits intermediaries' ties to persons making unpermitted investment recommendations. Chapter IIIA prohibits persons regulated by the Board and their agents from associating with any person who provides advice or recommendations on securities or who makes claims about returns or performance, unless that person is registered with or permitted by the Board; specified digital platforms meeting Board-prescribed safeguards and bona fide investor education providers are excluded; regulated persons must ensure associates do not undertake the proscribed activities; association includes monetary transactions, referrals and IT interactions; the Board may take action, including under Chapter V, for contraventions.
