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

In its filing with the Commission, the Exchange included statements concerning the purpose of and basis for the proposed rule

most significant parts of such statements.

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

1. Purpose

The purpose of the proposed rule change is to convert the Exchange and TXSE Group, a limited liability company and corporation
respectively, and each organized under the laws of the State of Delaware, to a limited liability company and corporation,
respectively, each organized under the laws of the State of Texas. Specifically, the Exchange proposes to: (i) amend and restate
the Seventh Amended and Restated Stockholders' Agreement of TXSE Group as the Eighth Amended and Restated Stockholders' Agreement,
adopt the Group Certificate of Formation to replace the Sixth Amended and Restated Certificate of Incorporation of TXSE Group
filed in the State of Delaware, and adopt the Bylaws in the State of Texas to replace the Second Amended and Restated Bylaws
of TXSE Group; and (ii) adopt the TXSE Certificate of Formation to replace the Certificate of Formation of TXSE filed in the
State of Delaware and adopt the Company Agreement as a limited liability company in Texas to replace the Third Amended and
Restated Limited Liability Company Agreement of TXSE as a Delaware limited liability company. The above changes reflect the
following: (1) the proposed conversion of the Exchange and TXSE Group to be a Texas limited liability company and Texas corporation,
respectively, (2) a change in the address and name of the registered office and registered agent of the Exchange and TXSE
Group, (3) certain changes reflected in the Group Certificate of Formation, the Stockholders' Agreement, Bylaws, TXSE Certificate
of Formation, and Company Agreement, all of which are attributed to the conversion of the Exchange and TXSE Group to be Texas
entities, and the ensuing compliance with applicable Texas laws therein, and (4) certain non-substantive and non-material
conforming changes.

The Exchange is proposing to reincorporate both the Exchange and TXSE Group to become a Texas limited liability company, and
a Texas corporation, respectively. By virtue of this conversion, The Exchange will convert from a limited liability company
organized under the laws of the State of Delaware to a limited liability company organized under the laws of the State of
Texas, and TXSE Group will convert from a corporation organized under the laws of the State of Delaware to a corporation organized
under the laws of the State of Texas. In both instances all rights, privileges, powers, property, and liabilities shall vest
to the newly formed entities at the time of conversion.

All changes described herein would become operative upon the filing of the Certificates of Conversion with the Delaware Secretary
of State and the Certificates of Formation, Certificates of

  Conversion, and Plans of Conversion with Texas Secretary of State.

The changes proposed by the Exchange do not affect the duties of the Exchange's role as a “national securities exchange” registered
under Section 6 of the Act (5) in that they do not materially alter TXSE Group's or the Exchange's governance framework; amend any of provisions related
to the Exchange's obligations as a self-regulatory organization or that would impact the Exchange's ability to carry out its
obligations as a self-regulatory organization; or to alter any provisions dealing with the availability or protection of information,
books and records, undue influence, conflicts of interest, unfair control by an affiliate, or regulatory independence of the
Exchange. The Exchange's proposed documents and changes described herein will not substantively impact the Exchange's existing
rules or its current obligations and requirements under its governing documents or the Act, including, but not limited to
Section 6(b)(3) of the Act with respect to fair representation of the members of the Exchange in the selection of directors,
and administration, of the Exchange. The Exchange is not proposing any changes to its rulebook. In fact, the only changes
being proposed are amendments designed to contemplate the conversion of the Exchange and TXSE Group to be Texas entities,
and to comply with applicable Texas laws.

To effectuate the changes, the Exchange proposes the following amendments, which are further reflected in Exhibit 5.

Group Certificate of Formation

In order to convert from a Delaware corporation to a Texas corporation, a Certificate of Conversion will be filed with the
Secretary of State of the State of Delaware in addition to a Certificate of Conversion and a Certificate of Formation which
will be filed with the Secretary of State of the State of Texas. The conversion certificates are necessary to effectuate the
conversion of TXSE Group from a Delaware corporation to a Texas Corporation pursuant to the Texas Business Organizations Code
(“TBOC”) and the Delaware Limited Liability Company Act. All rights, privileges, powers, property, and liabilities of TXSE
Group shall transfer to the new Texas Corporation upon filing.

The TBOC requires that a Certificate of Formation be filed with the Secretary of State in order to successfully accomplish
the formation of a new corporation. Currently, many of the naming conventions and certain provisions of the Sixth Amended
and Restated Certificate of Incorporation of TXSE Group are, rightfully, based on Delaware corporate requirements. Thus, in
effectuating the change from a Delaware corporation to a Texas corporation, it is proposed that, as part of the conversion
process, the Certificate of Formation correctly reflect and address the change of state of incorporation and ensure alignment
and compliance with applicable Texas laws. The Group Certificate of Formation is substantively similar to the Sixth Amended
and Restated Certificate of Incorporation. With respect to the Group Certificate of Formation that is the subject of this
filing, the Exchange is proposing to make the following changes:

• All references to the “Sixth Amended and Restated Certificate of Incorporation of TXSE Group Inc.” will be updated to be the “Certificate of Formation of TXSE Group Inc.” Additionally, references to that title, or to the Certificate of Incorporation generally, throughout the document will be updated to reflect the above change and appropriate nomenclature.
• All references to Delaware, notwithstanding the reference to the Firm's history as a Delaware corporation in preamble Section 1, will be updated to reflect the new state of incorporation, Texas.
• All references to “stockholder(s)” will be updated to “shareholder(s).”

• Preamble numbers 2, 3, 4, 5, 6, 7, 8, 9, and 10 that identify the historical updates made to amend and restate the Delaware Certificate of Incorporation will be removed.
• A new preamble number 2 will be added to identify the conversion of TXSE Group from a Delaware corporation to a Texas corporation, and include the date of conversion, pursuant to filing with the respective states.

○ That the initial mailing address of the corporation is 4450 Travis Street, Suite 650, Dallas, Texas 75205.

• The Third Article will remove the reference the Delaware General Corporation Law (“DGCL”) and include the TBOC. Other references to the DGCL elsewhere in the document will also be updated to be the TBOC.
• The Fourth Article will be updated as follows: ○ That a “certificate of designation” will be updated to be identified as a “statement of resolution.”

○ With respect to preferred stock, the following will be removed “and no vote of the holders of any series of Preferred Stock,

of any Preferred Stock Designation.” and replaced with “Except as otherwise required by this Certificate of Formation, and
notwithstanding any provision of the TBOC to the contrary, (y) all classes or series of stock are entitled to vote as a single
class or series, and separate voting by class or series is not required, for the purpose of approving any matter, including
in connection with any “fundamental action” or “fundamental business transaction” as defined in the TBOC, and (z) the approval
of a “fundamental action” or “fundamental business transaction” as defined in the TBOC requires the affirmative vote of the
holders of at least a majority of the voting power of all of the outstanding shares of stock entitled to vote thereon, voting
together as a single class.” (6)

• A new Fifth Article will be added to identify that the corporation affirmatively elects to be governed by Section 21.419
of the TBOC, with respect to a minimum of 3% of shares outstanding for a derivative proceeding to be instituted. Specifically,
any time TXSE Group has any class or series of its Common Stock listed on a national securities exchange (as defined in Section
1.002(55-a) of the TBOC) or has 500 or more shareholders, no shareholder (as defined in Section 21,551(2) of the TBOC) of
TXSE Group may institute or maintain a derivative proceeding unless the shareholder, as the time of the derivative proceeding
is instituted, holds at least three (3)

  percent of the outstanding shares of TXSE Group. [(7)]()

• The Fifth, Sixth, Seventh, Eighth, Ninth, Tenth, Eleventh, Twelfth, Thirteenth, Fourteenth, Fifteenth, Sixteenth, Seventeenth, and Eighteenth Articles will be updated to be the Sixth, Seventh, Eighth, Ninth, Tenth, Eleventh, Twelfth, Thirteenth, Fourteenth, Fifteenth, Sixteenth, Seventeenth, Eighteenth, and Nineteenth Articles, respectively.

• The new Seventeenth Article will be updated as follows: ○ The removal of the Delaware Court of Chancery and the addition of the Business Court in the First Business Court Division, or if the Business Court determines it lacks jurisdiction, a federal district court in the Northern District of Texas, Dallas Division, as the exclusive forum for derivative actions, and breaches of fiduciary duty, among other claims.

○ Specifically, with respect to claims brought regarding breaches of fiduciary duty, language will be added to contemplate

to or involve the corporation.

Court, including any claims within the supplemental jurisdiction of the Business Court, that any person holding an interest

○ A new subsection (c) will be added, identifying shareholders' waiver of the right to a jury trial. (9)

Stockholders' Agreement

Following the conversion of both TXSE Group and the Exchange, from Delaware entities to Texas entities, it is proposed that
TXSE Group amend its Stockholders' Agreement. Currently, many of the naming conventions and certain provisions of the Seventh
Amended and Restated Stockholders' Agreement are based on Delaware corporate requirements, and thus in effectuating the change
from a Delaware corporation to a Texas corporation, it is proposed that the Stockholders' Agreement be updated to correctly
reflect and address the change and ensure alignment and compliance with applicable Texas laws. The proposed Stockholders'
Agreement is substantively similar to the previous iteration, with non-substantive and non-material updates being proposed.
With respect to the specific updates in the Stockholders' Agreement, the Exchange is proposing to make the following changes:

• All references to the “Seventh Amended and Restated Stockholders' Agreement will be updated to be the “Eighth Amended and Restated Stockholders' Agreement.”
• The date will be updated to reflect the Stockholders' Agreement is being made as of [•], 2026.

Bylaws

Following the conversion of both TXSE Group and the Exchange, from Delaware entities to Texas entities, it is proposed that
TXSE Group adopt its Bylaws. Currently, the Second Amended and Restated Bylaws of TXSE Group Inc. are, rightfully, based on
Delaware corporate requirements, in addition to certain naming conventions of the document. Thus, in effectuating the change
from a Delaware corporation to a Texas corporation, it is proposed that, as part of the conversion process, the Bylaws correctly
reflect and address the change of state of incorporation and ensure alignment and compliance with applicable Texas laws. The
Bylaws are substantively similar to the Second Amended and Restated Bylaws of TXSE Group Inc. With respect to the specific
updates to the Bylaws, the Exchange is proposing to make the following changes:

• The title of the Bylaws document will be renamed from “Second Amended and Restated Bylaws of TXSE Group Inc.” to “Bylaws of TXSE Group Inc.” Additionally, references to the title, will be updated to reflect the above.

TXSE Certificate of Formation

In order to convert from a Delaware limited liability company to a Texas limited liability company, a Certificate of Conversion
will be filed with the Secretary of State of the State of Delaware, in addition to a Certificate of Conversion and a Certificate
of Formation which will be filed with the Secretary of State of the State of Texas. The conversion certificates are necessary
to effectuate the conversion of TXSE from a Delaware limited liability company to a Texas limited liability company pursuant
to the TBOC and the Delaware Limited Liability Company Act. All rights, privileges, powers, property, and liabilities of TXSE
Group shall transfer to the Exchange upon filing.

The TBOC requires that a Certificate of Formation be filed with the Secretary of State in order to successfully accomplish
the formation of the new limited liability company. (22) With respect to the TXSE Certificate of Formation, the Exchange is proposing to make the following updates. The Exchange notes
here, that the State of Delaware and the State of Texas have different forms (23) with respect to their limited liability company certificates of formation. The changes that will be identified below reflect
the non-substantive changes, as opposed to differences in the templated form between the two states:

• The name of the registered agent will be updated from “Capitol Services, Inc.” to “Capitol Corporate Services, Inc.”
• The address of the registered agent will be updated to become 1501 S MoPac Expy., Suite 220, Austin, TX 78746.

Company Agreement

Following the conversion of both TXSE Group and the Exchange, from Delaware entities to Texas entities, it is proposed that
TXSE adopt its Company Agreement. Currently, the Third Amended and Restated Limited Liability Company Agreement of Texas Stock
Exchange is, rightfully, based on Delaware limited liability company requirements, in addition to certain naming conventions
of the document. Thus, in effectuating the change from a Delaware limited liability company to a Texas limited liability company,
it is proposed that as part of the conversion process, the Company Agreement correctly reflect and address the change of state
of incorporation and ensure alignment and compliance with applicable Texas laws. The Company Agreement is substantively similar
to the Third Amended and Restated Limited Liability Company Agreement of Texas Stock Exchange LLC. With respect to the specific
updates to the Company Agreement, the Exchange is proposing to make the following updates:

• The title of the document will be updated from the “Third Amended and Restated Limited Liability Company Agreement of Texas Stock Exchange LLC” to “Company Agreement of Texas Stock Exchange.” Further, all references to the “Third and Amended Restated Limited Liability Company Agreement” will be updated to “Company Agreement.” Additionally, instances where “Limited Liability Company Agreement” is identified will be updated to either “Company Agreement” or “Agreement.”

• The previous statement about the Company Agreement amending and restating the entirety of the Second Amended and Restated
  Limited Liability Company Agreement will be removed.

• The Definitions Section will be updated as follows:
  ○ subsections (a) that defines “Act” as the Delaware Limited Liability Company Act will be removed.

○ subsections (b), (c), (d), (e), (f), (g), (h), (i), (j), (k), (l), (m), (n), (o), (p),(q), (r), (s), (t), (u), (v), (w),
(x), (y), (z), (aa), (bb), (cc), (dd), (ee), (ff), and (gg), will be updated to be (a), (b), (c), (d), (e), (f), (g), (h),
(i), (j), (k), (l), (m), (n), (o), (p),(q), (r), (s), (t), (u), (v), (w), (x), (y), (z), (aa), (bb), (cc), (dd), (ee), and
(ff), respectively.

○ Subsection (gg) will be added to include the definition of “TBOC” as the Limited Liability Company Law, Title 3 of the Texas
Business Organization Code, as the same may be amended from time to time.

• Section 2, Article 2, will remove the old date of formation, and will input the new date of formation, on the date of filing.
• The name of the registered agent will be updated from “Capitol Services, Inc.” to “Capitol Corporate Services, Inc.”

○ The section will be renamed “Termination” from “Dissolution.” Reference to dissolution within the

  section will be updated to reflect this change.

○ The phrase “the entry of a decree of a judicial dissolution” will be updated to “a determination by the court.”

○ Section 18.802 of the Act will be replaced with Section 1011.621 of the TBOC.

○ In subsection (d), references to canceling a certificate of formation will be updated to contemplate the filing of a certificate
of termination in accordance with the TBOC.

• Section 16 of Article X will add a statement that says “In this regard, the Company affirmatively elects to be governed by Section 101.256 of the TBOC.” • Section 17 of Article X will remove the following: “Any agreement to pay any amount and any assumption of liability in this Agreement contained, express or implied, shall be only for the benefit of the LLC Member and its respective heirs, successors, and permitted assigns, and such agreements and assumptions shall not inure to the benefit of the obliges of any indebtedness of any other party, whomsoever, adeemed to be a third party beneficiary of this Agreement” and replace with “Subject to Article X, Section 10 of this Agreement, nothing in this Agreement, express or implied, is intended to confer upon any party, other than the parties, hereto and their respective permitted assigns, any rights, remedies, obligations or liabilities under or by reason of this Agreement and no person who is not a party to this Agreement may rely on the terms hereof.” (25)

2. Statutory Basis

The Exchange believes the proposed rule change is consistent with the Act and the rules and regulations thereunder applicable
to the Exchange and, in particular, the requirements of Section 6(b) of the Act. (26) Specifically, the Exchange believes the proposed rule change is consistent with the objectives of Section 6(b)(1) (27) of the Act in particular, in that such amendments enable the Exchange to be so organized as to have the capacity to be able
to carry out the purposes of the Act and to comply with the provisions of the Act, the rules and regulations thereunder, and
the rules of the Exchange. The Exchange also believes that the proposed amendments are consistent with Section 6(b)(5) of
the Act, (28) which requires the rules of an exchange to be 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 changes being proposed, both in form and substance, reflect the conventions of moving both the Exchange and TXSE Group
entities from Delaware to Texas. The differences enable the Exchange to be able to be so organized as to have the capacity
to be able to carry out the purposes of the Act and to comply, and to enforce compliance by its exchange members and persons
associated with its exchange members, with the provisions of the Act, the rules and regulations thereunder, the rules of the
exchange, and the applicable laws of Texas. Furthermore, the proposed differences within the updated documents facilitate
compliance with Texas law, update addresses, and naming conventions, and the Exchange believes the proposed amendments are
consistent with, and will not interfere with, the self-regulatory obligations of the Exchange. In other words, these are changes
that remove impediments to, and perfect the mechanism of, a free and open market by removing potential confusion that may
result from corporate governance provisions that are either unclear or inconsistent with governing law.

Therefore, the Exchange believes these proposed changes are appropriate and consistent with Section 6(b)(1) of the Act, in
that such amendments enable the Exchange to be so organized as to have the capacity to carry out the purposes of the Act and
to comply with the provisions of the Act, the rules and regulations thereunder, and the rules of the Exchange. Further, such
amendments will not impair the ability of the Exchange to carry out its functions and responsibilities as an “exchange” under
the Act, and the rules and regulations promulgated thereunder, nor do such amendments impair the ability of the Commission
to enforce the Act and the rules and regulations promulgated thereunder with respect to the Exchange.

The Exchange believes the proposed amendments described in this proposal are consistent with, and will not interfere with,
the self-regulatory obligations of the Exchange. The Exchange importantly notes that it is not proposing to materially alter
TXSE Group's or the Exchange's existing governance framework, materially amend any of the provisions related to the Exchange's
obligations as a self-regulatory organization or that would impact the Exchange's ability to carry out its obligations as
a self-regulatory organization, or to alter any provisions dealing with the availability or protection of information, books
and records, undue influence, conflicts of interest, unfair control by an affiliate, or regulatory independence of the Exchange. (29) Further, the Exchange's proposed documents and changes described herein will not substantively impact the Exchange's existing
rules or its current obligations and requirements under its governing documents or the Act, including, but not limited to
Section 6(b)(3) of the Act with respect to fair representation of the members of the Exchange in the selection of directors,
and administration, of the Exchange.

For these reasons, the Exchange believes such amendments would enable the Exchange to be so organized as to have the capacity
to carry out the purposes of the Act and to comply with the provisions of the Act, the rules and regulations thereunder, and
the rules of the Exchange, promote just and equitable principles of trade, remove impediments to and perfect the mechanism
of a free and open market, and protect investors and the public interest.

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

The Exchange does not believe that the proposal will impose any burden on competition that is not necessary or appropriate
in furtherance of the purposes of the Act. The proposal is not intended to address competitive issues but rather is concerned
with the changes to the corporate documents of the Exchange and TXSE Group necessary to reincorporate both the Exchange and
TXSE Group in the state of Texas, as described above.

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

Others

The Exchange has neither solicited nor received written comments on the proposed rule change.

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

Pursuant to Section 19(b)(3)(A) of the Act (30) and 19b-4(f)(6) (31) thereunder, the Exchange has designated this proposal as one that effects a change that: (i) does not significantly affect
the protection of investors or the public interest; (ii) does not impose any significant burden on competition; and by its
terms, does not become operative for 30 days from the date on which it was filed, or such shorter time as the Commission may
designate if consistent with the protection of investors and the public interest. (32)

A proposed rule change filed under Rule 19b-4(f)(6) normally does not become operative prior to 30 days after the date of
its filing. However, Rule 19b-4(f)(6)(iii) (33) permits the Commission to designate a shorter time if such action is consistent with the protection of investors and public
interest. The Exchange has requested that the Commission waive the 30-day operative delay so that the Exchange and TXSE Group's
reincorporation may take effect promptly. The Exchange states that the proposed changes do not materially alter the Exchange
or TXSE Group's existing governance framework, nor do they raise novel issues not previously considered by the Commission.
Therefore, the Commission believes that it is consistent with the protection of investors and the public interest for the
Exchange to implement this proposal prior to 30 days from the date of filing. Accordingly, the Commission hereby waives the
30-day operative delay and designates the proposed rule change operative upon filing. (34)

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
will institute proceedings to determine whether the proposed rule change should be approved or disapproved.

(6) For clarity, the proposed new language in this provision is substantially similar to the language in the current Sixth Amended
and Restated Certificate of Incorporation of TXSE Group, and the only meaningful difference is that the proposed change provides
further clarity that all classes of stock are entitled to vote as a single class; See also TEX BUS ORG CODE Sections 21.456-458 (outlining voting requirements with respect to fundamental business transactions).

(7) See TEX BUS ORG CODE Section 21.552.

(8) See TEX BUS ORG CODE Section 21.352 (identifying that a special meeting may be called by: (1) the president, board of directors,
or any other person authorized to call special meetings by the certificate of formation or bylaws of a corporation, or (2)
the holders of the percentage of shares specified in the certificate of formation, not to exceed 50 percent of the shares
entitled to vote or, if no percentage is specified, at least 10 percent of all the shares of the corporation entitled to vote
at the proposed special meeting).

(9) Subsection (c) is intended to provide clarity in that the appropriate forum for claims will be the Business Court in the
First Business Court Division, as specified in subsection (b) of Article 17. The changes reflect no substantive difference
in that both the Delaware Court of Chancery and the Texas Business Courts do not provide for jury trials.

(10) For clarity, this change refers to generic references to stockholders and shareholders, respectively, and does not alter
any defined terms within the Stockholders' Agreement.

(11) The term “Controlling Stockholders” is a defined term within the Stockholders' Agreement and is defined as “one or more Stockholders
holding at least a majority of the Shares held in aggregate by the Stockholders.”

(12) See TEX BUS ORG CODE Section 3.151 (requiring that corporate records be maintained in a paper form or a form that is convertible
to paper).

(13) See TEX BUS ORG CODE Section 21.456 (requiring 21 days' notice for shareholder meeting at which a “fundamental business transaction”
will be considered).

(14) See TEX BUS ORG CODE Section 21.372 (requiring that shareholder lists be prepared at least 11 days before the meeting).

(15) See TEX BUS ORG CODE Section 21.372 (providing more detailed requirements for shareholder list information, including specification
of share types and vote counts).

(16) As part of the proposed amendments herein, TXSE Group intends to remove Section 2.8 from the Bylaws to avoid potential inconsistency
between the governing documents, endeavoring to ensure that the Group Certificate of Formation serves as the single authoritative
source for shareholder voting rights. This approach also attempts to reduce the risk of any inadvertent conflict between the
Bylaws and the Group Certificate of Formation; Supra note 6.

(17) See TEX BUS ORG CODE Section 21.368 (providing that a proxy is not valid after 11 months after the date the proxy is executed
unless otherwise provided by the proxy).

(18) See generally TEX BUS ORG CODE (TBOC does not require written ballots). As part of the proposed amendments described herein, TXSE Group
is electing to qualify that election ballots do not need to be written in conformation with the TBOC.

(19) See TEX BUS ORG CODE Section 21.410 (providing that the board of directors may not fill more than two directorships during a period
between two successive annual meetings). The Exchange notes, however, that it will continue to comply with existing obligations
and composition requirements for the Exchange Board, as specified elsewhere in the Bylaws, its other governing documents,
and its rules.

(20) As part of the proposed amendments described herein, TXSE Group is electing to remove the Treasurer as an office that cannot
be left unfilled.

(21) For clarity, forum selection provisions have been moved entirely to the Group Certificate of Formation.

(22) See TEX BUS ORG CODE Section 101.051; See also TEX BUS ORG CODE Section 21.051.

(23) See generally Form 205 of the Secretary of State of the State of Texas.

(24) See TEX BUS ORG CODE Section 101.621. The TBOC uses different terminology and procedures with respect to winding up a limited
liability company. Under Texas law, limited liability companies are terminated rather than dissolved.

(25) The change above is not intended to affect or alter any rights but rather provides clarity that explicitly identifies the
absence of any third-party beneficiary rights.

to file the proposed rule change at least five business days prior to the date of filing of the proposed rule change, or such
shorter time as designated by the Commission. The Exchange has satisfied this requirement.

(33) 17 CFR 240.19b-4(f)(6)(iii).

(34) For purposes only of waiving the 30-day operative delay, the Commission has also considered the proposed rule's impact on
efficiency, competition, and capital formation. See 15 U.S.C. 78c(f).

(35) 17 CFR 200.30-3(a)(12), (59).
