The Securities and Exchange Commission (SEC) published a Comment Request on extending Rule 17 Ad-27, which requires exempt entities that perform matching services to facilitate the settlement of securities transactions (referred to as a “central matching service provider” or “CMSP”) to establish, implement, maintain and enforce policies and procedures reasonably designed to facilitate straight-through processing for transactions involving broker-dealers and their customers.
CMSPs electronically facilitate communication among a broker-dealer, an institutional investor or its investment adviser, and the institutional investor’s custodian to reach agreement on the details of a securities trade. CMSP data must be reported in Inline XBRL format. Comments must be submitted by June 22, 2026.
