SEC Regulation Best Interest (Reg BI)

On June 5, 2019, the SEC adopted Regulation Best Interest (Reg BI) under the Securities Exchange Act of 1934. Reg BI establishes a “best interest” standard of conduct for broker-dealers and associated persons when they make a recommendation to a retail customer of any securities transaction or investment strategy involving securities, including recommendations of types of accounts.

As part of the rulemaking package, the SEC also adopted new rules and forms to require broker-dealers and investment advisers to provide a brief relationship summary, Form CRS, to retail investors. In addition, the SEC published interpretations, linked below, concerning investment advisers’ standard of conduct under the Investment Advisers Act of 1940, and the “solely incidental” prong of the broker-dealer exclusion from the Advisers Act.

Firms must comply with Reg BI and Form CRS by June 30, 2020. The Advisers Act interpretive releases were effective on July 12, 2019.

FINRA Resources

FINRA will assist members with their implementation of Reg BI and Form CRS in various ways, such as by providing resources to assist firms in their implementation efforts. In addition, FINRA intends to hold in-person meetings and workshops to assist with these efforts. These will be publicly announced on finra.org and in other FINRA communications.

As with other SEC rules, FINRA will examine for and enforce compliance with Reg BI and, in doing so, FINRA will adhere to SEC guidance and interpretations. FINRA staff expects to work with SEC staff to ensure consistency in examining broker-dealers and their associated persons for compliance with Reg BI. In addition, FINRA will review FINRA rules to see whether changes are needed to align FINRA rules with the SEC’s rulemaking. Any proposed changes to FINRA rules will be filed with the SEC for public comment and available on FINRA’s website.
