[^5] The Proposed Amendment was published for comment in the *Federal Register* on March 19, 2025 (“Notice”). [^6]
[^1] In 2012, the Commission adopted Rule 613 of Regulation NMS, which required the Participants to jointly develop and submit to the Commission a national market system plan to create, implement, and maintain a consolidated audit trail (the “CAT”). *See* Securities Exchange Act Release No. 67457 (July 18, 2012), 77 FR 45722 (Aug. 1, 2012); 17 CFR 242.613 (“Rule 613”). On November 15, 2016, the Commission approved the CAT NMS Plan. *See* Securities Exchange Act Release No. 79318, 81 FR 84696 (Nov. 23, 2016) (“CAT NMS Plan Approval Order”). The CAT NMS Plan is Exhibit A to the CAT NMS Plan Approval Order. *See* CAT NMS Plan Approval Order, at 84943-85034.
[^2] 15 U.S.C. 78k-1(a)(3).
[^3] 17 CFR 242.608.
[^4] A “Customer” means “the account holder(s) of the account at a registered broker-dealer originating the order; and any person from whom the broker-dealer is authorized to accept trading instructions for such account, if different from the account holder(s).” *See* CAT NMS Plan, *supra* note 1, at section 1.1.

[^6]*See* Securities Exchange Act Release No. 102665 (Mar. 13, 2025), 90 FR 12845. Comments received in response to the Notice can be found on the Commission's website at *https://www.sec.gov/comments/4-698/4-698-f.htm.* While the SEC is currently “accepting” comments, in that we will not prevent the submission of letters via the usual methods (webform, email, or mail), the SEC will not be posting them until after the resumption of duties. Please note that there may be a delay in the public availability of comments after the resumption of duties; comments will be treated as if received on the original submission date.
On May 28, 2025, the Participants filed Amendment No. 1 to the Proposed Amendment (“Amendment No. 1”). [^7] On June 17, 2025, the Commission noticed Amendment No. 1 for comment and instituted proceedings to determine whether to approve or disapprove the Proposed Amendment, as modified by Amendment No. 1. [^8] On September 11, 2025, pursuant to Rule 608(b)(2)(i) of Regulation NMS, [^9] the Commission extended the period within which to conclude proceedings regarding the Proposed Amendment, as modified by Amendment No. 1, to 240 days from the date of publication of the Notice. [^10] The 240th day after publication of the Notice is November 14, 2025.

[^8]*See* Securities Exchange Act Release No. 103288, 90 FR 26637 (June 23, 2025). Comments received in response to Amendment No. 1 can be found on the Commission's website at *https://www.sec.gov/comments/4-698/4-698-f.htm.*
[^9]*See* 17 CFR 242.608(b)(2)(i).
[^10]*See* Securities Exchange Act Release No. 103946, 90 FR 44734 (Sept. 16, 2025).
Rule 608(b)(2)(ii) of Regulation NMS provides that the time for conclusion of proceedings to determine whether a national market system plan or proposed amendment should be approved or disapproved may be extended for an additional period up to 60 days (up to 300 days from the date of notice publication) if the Commission determines that a longer period is appropriate and publishes the reasons for such determination or the plan participants consent to the longer period. [^11] The Commission is extending this 240-day period.
[^11]*See* 17 CFR 242.608(b)(2)(ii).
The Commission finds that it is appropriate to designate a longer period within which to conclude proceedings regarding the Proposed Amendment, as modified by Amendment No. 1, so that it has sufficient time to consider the important policy issues raised by the Proposed Amendment, as modified by Amendment No. 1, and the comments received. Accordingly, pursuant to Rule 608(b)(2)(ii) of Regulation NMS, [^12] the Commission designates January 13, 2026 as the date by which the Commission shall conclude the proceedings to determine whether to approve or disapprove the Proposed Amendment, as modified by Amendment No. 1 (File No. 4-698).
[^12]*Id.*
By the Commission.

Assistant Secretary.
