Regulation Best Interest: Best Interest and Suitability—How They Differ (Part 5)
Regulation Best Interest (Reg BI) imposes a “best interest” standard of care on broker-dealers for their recommendations of securities and investment strategies to retail customers. That raises the question, what does best interest mean and how does it differ from suitability?
Parts 1, 2 and 3 of this series (Best Interest Standard of Care for Advisors #30, #31 and #32) explain that the difference between best interest and suitability is not easily defined. However, based on the SEC’s discussion in the Adopting Release for Reg BI, I provided five examples of where best interest appears to impose a more demanding standard than suitability. These examples focus on the Reg BI requirement that broker-dealers (and their registered representatives) consider costs in the development of recommendations. While costs are not the only factor to be considered, the SEC says that “best interest” makes cost a more important factor than it was under the suitability standard.
