SEC staff statement maps municipal advisors' antifraud exposure in disclosure prep
SEC staff guidance says a municipal advisor can face federal antifraud liability over misstatements in a disclosure document it helped prepare, even absent a written engagement, and prescribes scope-specific compliance measures.
The SEC's Office of Municipal Securities published a Statement on September 16, 2026 (on non-solicitor municipal advisors' role in disclosure) explaining when a municipal advisor's participation in drafting, reviewing or editing a municipal securities disclosure document triggers federal antifraud liability under Securities Act Section 17(a) and Exchange Act Section 10(b) and Rule 10b-5. Liability can attach even if the advisor never agreed in writing to advise on the document and even where the misstatement came from language supplied by the issuer, provided the advisor knew or in the exercise of care should have known of it. Duties turn on role and circumstances, not label: OMS flags possible Section 15B fiduciary and MSRB Rules G-17 and G-42 duty-of-care exposure where the advisor agrees to prepare the document, actually assists with it, or routinely participates, creating an expectation of continued participation. Although non-binding, the Statement offers a compliance menu — engagement letters specifying exactly which documents and in which capacity (provider, drafter, reviewer, editor, assembler) the advisor covers; prompt amendment as the role evolves; inquiry commensurate with the role, heightened in a competitive sale before an underwriter is in place; written disclosure policies; and caution that disclaimers cannot cure violations. Counsel should note the staff's suggestion that its reasoning may extend to other disclosure-document participants, including disclosure counsel.
