Commission (the ``Commission''), pursuant to Section 19(b)(1) of the 
Securities Exchange Act of 1934 (the ``Act''),\1\ and Rule 19b-4 
thereunder,\2\ a proposed rule change to amend Exchange Rule 307,

security. The proposed rule change was published for comment in the 
Federal Register on May 8, 2023.\3\ On June 14, 2023, pursuant to 
Section 19(b)(2) of the Act,\4\ the Commission designated a longer 
period within which to approve the proposed rule change, disapprove the 
proposed rule change, or institute proceedings to determine whether to 
approve or disapprove the proposed rule change.\5\ The Commission has 
received one comment regarding the proposal.\6\ On August 2, 2023, the

\7\ to determine whether to approve or disapprove the proposed rule 
change.\8\

    Section 19(b)(2) of the Act \9\ provides that, after initiating 
disapproval proceedings, the Commission shall issue an order approving 
or disapproving the proposed rule change not later than 180 days after 
the date of publication of notice of filing of the proposed rule 
change. The Commission may extend the period for issuing an order 
approving or disapproving the proposed rule change, however, by not 
more than 60 days if the Commission determines that a longer period is 
appropriate and publishes the reasons for such determination. The 
proposed rule change was published for comment in the Federal Register 
on May 8, 2023.\10\ The 180th day after the date of the publication of 
the proposed rule is November 4, 2023. The Commission is extending the 
time period for approving or disapproving the proposed rule change for 
an additional 60 days.

    The Commission finds that it is appropriate to designate a longer 
period within which to issue an order approving or disapproving the 
proposed rule change so that it has sufficient time to consider the 
proposed rule change and the issues raised therein, as well as the 
comment received. Accordingly, the Commission, pursuant to Section 
19(b)(2) of the Act,\11\ designates January 3, 2024, as the date by 
which the Commission shall either approve or

disapprove the proposed rule change (File No. SR-MIAX-2023-19).
