SEC Proposes Rule Amendments for Investor Protections in Communication Protocol Systems and ATSs

The SEC’s rule proposal to include treasury markets platforms within regulation ATS would: (1) expand Regulation ATS for alternative trading systems (ATS) that trade government securities, NMS stock, and other securities; (2) extend Regulation SCI to ATSs that trade government securities, and (3) update the SEC rule regarding the definition of an “exchange” to address a regulatory gap.
The proposed amendments would also provide new requirements for these entities:
- Communication Protocol Systems must register as an exchange or operate under the ATS exemption, which includes: (a) registering as a broker-dealer; (b) becoming a member of a Self-Regulatory Organization, and (c) complying with Regulation ATS.
- Government Securities ATSs must file a public Form ATS-N via EDGAR that would disclose information about their processes and the ATS-related activities of the registered broker-dealer or government securities broker or dealer that operates the ATS and its affiliates. For those currently operating under the exemption for certain government securities ATSs, compliance with the other applicable provisions of Regulation ATS is required.
- Existing NMS Stock ATSs must file an amendment to their existing disclosures in accordance with an updated Form ATS-N, which includes questions about the ATS’s interaction with related markets, liquidity providers, and activities the ATS undertakes to follow and monitor its market. NMS Stock ATSs must report changes to fee disclosures on Form ATS-N on or before the date a fee change is made.
- ATSs that trade all types of securities must update both Form ATS and ATS-R and electronically file them with the SEC via EDGAR. If subject to the Fair Access Rule, ATSs must be sure they meet the minimum requirements met for the reasonable written standards for granting, limiting, and denying access to ATS services that must be established and applied. Also required is justification for the reason each standard is fair and not unreasonably discriminatory.
