If a retirement plan’s circumstances include the trust’s investment in an employer security or a significant stake in a security beyond pooled investment fund shares, some TPAs drop a courtesy hint or reminder.
Some might do this quietly with the plan fiduciary’s lawyer, if the TPA has a working relationship with that lawyer. Otherwise, a TPA might suggest to the plan’s fiduciary that it ask its lawyer.
While many TPAs gives tons of legal advice (and on some topics know much more than many lawyers), the Corporate Transparency Act might be better suited for a handoff.
