The SEC has adopted the FINRA communication rule, which has some noticeable changes from the previous NASD rule, according to the article on Mondaq.com. One noticeable change was the consolidation of the six communication categories into three- institutional communication, retail communication and correspondence. The article further illuminated the difference between retail and institutional correspondence, per FINRA and The SEC.
There are also many other requirements set forth by FINRA and the SEC putting forth standards for retail and institutional communication as well as review procedures for such communication. The article also states that a "public appearance" is no longer a separate category and will fall under the new guidelines and requirements of the communication rule.
