A. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

1. Purpose

The Exchange proposes to delay the implementation of a rule change to automate FLEX and Cabinet Orders. The Exchange previously filed SR–Phlx–2023–22, a rule change that amended several Phlx Options 8 rules related to Phlx's trading floor.

FLEX Orders

With respect to FLEX Orders, SR–Phlx–2023–22 amended FLEX Orders in 3 ways. First, the Exchange amended the rules to require FLEX Orders to be reported into Phlx's Options Floor Based Management System or “FBMS,” thereby further automating the execution and reporting of FLEX Options. All executed FLEX contracts will be reported to OPRA and sent to The Options Clearing Corporation (“OCC”) for clearing, similar to all other equity, equity index and U.S. dollar-settled foreign currency options orders executed on the Exchange's trading floor. Second, the Exchange removed its RFQ process including the BBO Improvement Interval Process, with the rule change. Third, the Exchange reorganized Options 8, Section 34 to restructure the rule to include additional information which describes current FLEX trading on Phlx.

Cabinet Options

With respect to Cabinet Orders, SR–Phlx–2023–22 amended Options 8, Section 33 to require Cabinet Orders to be reported into FBMS. With this change, members and member organizations will be required to record all Cabinet Orders represented in the trading crowd into FBMS. All executed contracts will be reported to OPRA and sent to OCC for clearing similar to all other equity, equity index and U.S. dollar-settled foreign currency options orders executed on the Exchange's trading floor.

SR–Phlx–2023–22 stated that the rule change would be implemented on or before March 29, 2024. At this time, the Exchange proposes to delay the implementation of SR–Phlx–2023–22 to on or before August 30, 2024 to permit the Exchange additional time to code and test the functionality. The Exchange would issue an Options Trader Alert announcing the exact implementation date to members and member organizations.

2. Statutory Basis

The Exchange believes that its proposal is consistent with Section 6(b) of the Act, in general, and furthers the objectives of Section 6(b)(5) of the Act, in particular, in that it is designed to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general to protect investors and the public interest. The Exchange's proposal to delay the implementation of SR–Phlx–2023–22 to on or before August 30, 2024 is consistent with the Act and the protection of investors and the general public as it will permit the Exchange additional time to code and test the functionality.

B. Self-Regulatory Organization's Statement on Burden on Competition

The proposed rule change does not impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act. The Exchange's proposal to delay the implementation of SR–Phlx–2023–22 to on or before August 30, 2024 does not impose any burden on competition as it will permit the Exchange additional time to code and test the functionality.

C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants, or Others

No written comments were either solicited or received.

III. Date of Effectiveness of the Proposed Rule Change and Timing for Commission Action

Because the foregoing proposed rule change does not: (i) significantly affect the protection of investors or the public interest; (ii) impose any significant burden on competition; and (iii) become operative for 30 days from the date on which it was filed, or such shorter time as the Commission may designate, it has become effective pursuant to Section 19(b)(3)(A)(iii) of the Act and subparagraph (f)(6) of Rule 19b–4 thereunder.

At any time within 60 days of the filing of the proposed rule change, the Commission summarily may temporarily suspend such rule change if it appears to the Commission that such action is necessary or appropriate in the public interest, for the protection of investors, or otherwise in furtherance of the purposes of the Act. If the Commission takes such action, the Commission shall institute proceedings to determine whether the proposed rule should be approved or disapproved.
