One of the biggest regulatory developments of 2021 was the SEC’s issuance of a new marketing rule (Marketing Rule) – Rule 206(4)‑1 under the Investment Advisers Act of 1940 – which replaces the 1961 advertising rule and the 1979 cash solicitation rule. The Marketing Rule took effect on May 4, 2021, with an 18‑month transition period. Thus, compliance will become mandatory as of November 4, 2022. Many advisers have opted to wait until that deadline is closer to begin revising their marketing materials, policies and procedures. Now that it is January 2022, advisers that have not yet begun that process need to start soon given the extensive updates that may be required. An ACA Group program analyzed the key provisions of the Marketing Rule – along with its similarities to, and differences from, the existing regime – and offered practical insights on preparing marketing materials in accordance with the new rule. The program featured David W. Blass, partner at Simpson Thacher; Jeffrey Himstreet, vice president and corporate counsel at Prudential; and Julia Reyes and Kimberly Versace, respectively partner and director at ACA Group. This article outlines the key takeaways from the presentation.
