Notice
Summary

The change kicks in right away, making market watching tighter and teamwork smoother.
Analyzed Economic Effects
5 provisions identified: 5 benefits, 0 costs, 0 mixed.
Fewer Duplicate Exams, Lower Costs
Broker-dealer firms that are members of more than one participating SRO (``Common Members'') will have certain examination and enforcement duties assigned to a single regulator to reduce duplicate exams. The Plan covers Regulation NMS rules (SEA Rules 606, 607, 611, 612, and 613) and SRO Covered CAT Rules listed in Exhibit A, and the SEC approved and declared the amended Plan effective on May 14, 2026.
Who Regulates FINRA Members
For Regulation NMS rules that pertain to NMS stocks (Rules 607, 611, and 612), FINRA will serve as the Designated Regulation NMS Examining Authority (DREA) and will assume those examination and enforcement responsibilities for Common Members that are FINRA members. For Common Members that are not FINRA members, the member's DEA exchange will serve as the DREA and as the Designated CAT Surveillance Authority (DCSA) if that DEA exchange operates a national securities exchange or facility that trades NMS stocks.
SEC Declares Plan Effective Now
The SEC approved and declared the amended 17d-2 Plan effective on May 14, 2026. Parties who are not the DREA or DCSA for a particular Common Member are relieved of the regulatory responsibilities that the Plan allocates to that Common Member's DREA or DCSA.
No Fee for Performing Oversight
The Plan states that a DREA/DCSA shall not charge Participating Organizations for performing the regulatory responsibilities allocated under the Agreement. That ``No Charge'' rule is part of the Plan approved by the SEC and effective May 14, 2026.
New Participants Added to Plan
The amendment explicitly adds MX2 LLC and Texas Stock Exchange LLC (TXSE) as Participating Organizations and reflects the name change of Nasdaq BX to Nasdaq Texas. The amendment’s primary purpose is to include those new Participants in the allocation framework approved by the SEC.
