Joint Industry Plan; Order Instituting Proceedings To Determine 
Whether To Approve or Disapprove an Amendment to the National Market 
System Plan Governing the Consolidated Audit Trail

November 21, 2025.

I. Introduction

    On September 5, 2025, the Consolidated Audit Trail, LLC (``CAT 
LLC''), on behalf of the following parties to the National Market 
System Plan Governing the Consolidated Audit Trail (the ``CAT NMS 
Plan'' or ``Plan'') \1\: 24X National Exchange LLC, BOX Exchange LLC,

LLC, Nasdaq ISE, LLC, Nasdaq MRX, LLC, Nasdaq PHLX LLC, The NASDAQ 
Stock Market LLC, New York Stock Exchange LLC, NYSE American LLC, NYSE 
Arca, Inc., NYSE National, Inc., and NYSE Texas, Inc. (collectively, 
the ``Participants,'' or ``SROs'') filed with the Securities and 
Exchange Commission (``SEC'' or ``Commission'') pursuant to Section 
11A(a)(3) of the Securities Exchange Act of 1934 (``Act'' or ``Exchange 
Act''),\2\ and Rule 608 thereunder,\3\ a proposed amendment to 
implement a revised funding model (the ``Proposed Amendment'') for the 
consolidated audit trail (the ``CAT'') and to establish a fee schedule 
for Participant CAT fees in accordance with the Proposed Amendment.\4\ 
The Proposed Amendment was published for comment in the Federal 
Register on September 17, 2025.\5\
---------------------------------------------------------------------------

    \1\ In July 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 (``Rule 613 Adopting Release''); 17 CFR 242.613. 
On November 15, 2016, the Commission approved the CAT NMS Plan. See 
Securities Exchange Act Release No. 78318 (Nov. 15, 2016), 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

---------------------------------------------------------------------------

    This order institutes proceedings, under Rule 608(b)(2)(i) of 
Regulation NMS,\6\ to determine whether to disapprove the Proposed 
Amendment or to approve the Proposed Amendment with any changes or 
subject to any conditions the Commission deems necessary or 
appropriate.
---------------------------------------------------------------------------

---------------------------------------------------------------------------

II. Background

    Under the CAT NMS Plan, the Operating Committee of the Company, of 
which each Participant is a member, has the discretion (subject to the 
funding principles set forth in the Plan) to establish funding for the 
Company to operate the CAT, including establishing fees to be paid by 
the Participants and Industry Members.\7\
---------------------------------------------------------------------------

    \7\ The CAT NMS Plan defines ``Industry Member'' as ``a member 
of a national securities exchange or a member of a national 
securities association.'' See CAT NMS Plan, supra note 1, at Section 
1.1. See also id. at Section 11.1(b).
---------------------------------------------------------------------------

    Under the CAT NMS Plan, CAT fees are to be implemented in 
accordance with various funding principles, including an ``allocation 
of the Company's related costs among Participants and Industry Members 
that is consistent with the Exchange Act taking into account . . . 
distinctions in the securities trading operations of Participants and 
Industry Members and their relative impact upon the Company resources 
and operations'' and the ``avoid[ance of] any disincentives such as 
placing an inappropriate burden on competition and reduction in market 
quality.'' \8\ The Plan specifies that, in establishing the funding of 
the Company, the Operating Committee shall establish ``a tiered fee 
structure in which the fees charged to: (1) CAT Reporters \9\ that are 
Execution Venues,\10\ including ATSs,\11\ are based upon the level of 
market share; (2) Industry Members' non-ATS activities are based upon 
message traffic; and (3) the CAT Reporters with the most CAT-related 
activity (measured by market share and/or message traffic, as 
applicable) are generally comparable (where, for these comparability 
purposes, the tiered fee structure takes into consideration 
affiliations between or among CAT Reporters, whether Execution Venues 
and/or Industry Members).'' \12\
---------------------------------------------------------------------------

    \8\ Id. at Section 11.2(b) and (e).
    \9\ The CAT NMS Plan defines ``CAT Reporter'' as ``each national 
securities exchange, national securities association and Industry 
Member that is required to record and report information to the 
Central Repository pursuant to SEC Rule 613(c).'' Id. at Section 
1.1.
    \10\ The CAT NMS Plan defines ``Execution Venue'' as ``a 
Participant or an alternative trading system (`ATS') (as defined in 
Rule 300 of Regulation ATS) that operates pursuant to Rule 301 of 
Regulation ATS (excluding any such ATS that does not execute 
orders).'' Id.

Article XI for additional detail.
---------------------------------------------------------------------------

    On March, 13, 2023, the Participants to the CAT NMS Plan, pursuant 
to Section 11A of the Exchange Act \13\ and Regulation NMS 
thereunder,\14\ filed a proposed amendment to the CAT NMS Plan (the 
``2023 Funding Model Amendment'') to implement a revised funding model 
(the ``Executed Share Model'') for the CAT and to establish a fee 
schedule for Participant CAT fees in accordance with the Executed Share 
Model. The 2023 Funding Model Amendment was published for comment in 
the Federal Register on March 21, 2023.\15\ On September 6, 2023, the 
Commission approved the 2023 Funding Model Amendment (the

[[Page 54439]]

``2023 Funding Model Order'').\16\ On July 25, 2025, the United States 
Court of Appeals for the Eleventh Circuit issued an opinion vacating 
the 2023 Funding Model Order and remanding the matter to the Commission 
for further proceedings consistent with its opinion.\17\ The Court 
stayed the effect of its judgment for sixty days from the issuance of 
its mandate, which is December 1, 2025.\18\

III. Summary of Proposal \19\
---------------------------------------------------------------------------

    \19\ This section summarizes the proposed changes to the CAT NMS 
Plan. For a full discussion of the Proposed Amendment, including the 
Participants' justifications for the Proposed Amendment, such as 
comparability to existing fees, alternatives considered, fee pass-
throughs, treatment of FINRA, cost transparency (including the 
Historical CAT Costs prior to 2022) and satisfaction of the Exchange 
Act and CAT NMS Plan requirements, see Notice, supra note 5.
---------------------------------------------------------------------------

A. Executed Share Model

    As described in more detail in the Notice, CAT LLC proposes to 
replace the funding model set forth in Article XI of the CAT NMS Plan 
(``Original Funding Model'') with the Executed Share Model.\20\ The 
Original Funding Model involved a bifurcated approach, where costs 
associated with building and operating the CAT would be borne by (1) 
Industry Members (other than alternative trading systems (``ATSs'') 
that execute transactions in Eligible Securities (``Execution Venue 
ATSs'')) through fixed tiered fees based on message traffic for 
Eligible Securities, and (2) Participants and Industry Members that are 
Execution Venue ATSs for Eligible Securities through fixed tiered fees 
based on market share.\21\ In contrast, the Executed Share Model would 
charge fees based on the executed equivalent share volume of 
transactions in Eligible Securities rather than based on market share 
and message traffic.\22\ In addition, instead of charging fees to 
Industry Members, under the Executed Share Model, fees would be charged 
to each Industry Member that is a CAT Executing Broker \23\ for the 
buyer in a transaction in Eligible Securities (``CAT Executing Broker 
for the Buyer'' or ``CEBB'') and each Industry Member that is the CAT 
Executing Broker for the seller in a transaction in Eligible Securities 
(``CAT Executing Broker for the Seller'' or ``CEBS'').\24\
---------------------------------------------------------------------------

    \20\ The Participants state that other than the addition of a 
new proposed paragraph (e) to Section 11.3 of the CAT NMS Plan, 
which provides that each Participant agrees not to establish a new 
fee for passing through its CAT fees, the Proposed Amendment are 
identical to the amendments adopted in the 2023 Funding Model Order. 
See Notice, supra note 5, at 44910; see also infra Part III.A.3.e.
    \21\ See CAT NMS Plan, supra note 1, at Section 11.3(a) and (b).
    \22\ See Notice, supra note 5, at 44910. Proposed Section 
11.3(a)(i)(B) would describe how ``executed equivalent shares'' 
would be counted for purposes of calculating CAT Fees: (1) each 
executed share for a transaction in NMS stocks would be counted as 
one executed equivalent share; (2) each executed contract for a 
transaction in Listed Options would be counted using the contract 
multiplier applicable to the specific Listed Option in the relevant 
transaction; and (3) each executed share for a transaction in OTC 
Equity Securities would be considered 0.01 executed equivalent 
shares. See id. at 44933.
    \23\ The Executed Share Model would define ``CAT Executing 
Broker'' in Section 1.1 of the CAT NMS Plan as: (a) with respect to 
a transaction in an Eligible Security that is executed on an 
exchange, the Industry Member identified as the Industry Member 
responsible for the order on the buy-side of the transaction and the 
Industry Member responsible for the sell-side of the transaction in 
the equity order trade event and option trade event in the CAT Data 
submitted to the CAT by the relevant exchange pursuant to the 
Participant Technical Specifications; and (b) with respect to a 
transaction in an Eligible Security that is executed otherwise than 
on an exchange and required to be reported to an equity trade 
reporting facility of a registered national securities association, 
the Industry Member identified as the executing broker and the 
Industry Member identified as the contra-side executing broker in 
the TRF/ORF/ADF transaction data event in the CAT Data submitted to 
the CAT by FINRA pursuant to the Participant Technical 
Specifications; provided, however, in those circumstances where 
there is a non-Industry Member identified as the contra-side 
executing broker in the TRF/ORF/ADF transaction data event or no 
contra-side executing broker is identified in the TRF/ORF/ADF 
transaction data event, then the Industry Member identified as the 
executing broker in the TRF/ORF/ADF transaction data event would be 
treated as CAT Executing Broker for the Buyer and for the Seller. 
Id. at 44912.
    \24\ See Notice, supra note 5, at 44912.
---------------------------------------------------------------------------

    Under the Executed Share Model, CAT LLC proposes to establish two 
categories of CAT fees. The first category of CAT fees would be fees 
(``CAT Fees'') payable by Participants and Industry Members that are 
CAT Executing Brokers for the Buyer and for the Seller with regard to 
CAT costs not previously paid by the Participants (``Prospective CAT 
Costs'').\25\ The second category of CAT fees would be fees 
(``Historical CAT Assessments'') to be payable by Industry Members that 
are CAT Executing Brokers for the Buyer and for the Seller with regard 
to CAT costs previously paid by the Participants (``Past CAT 
Costs'').\26\ Each Historical CAT Assessment will recover an amount of 
``Historical CAT Costs,'' which will be Past CAT Costs minus Past CAT 
Costs reasonably excluded from Historical CAT Costs by the Operating 
Committee.\27\
---------------------------------------------------------------------------

    \25\ Id. at 44910; see also proposed Section 11.3(a). The 
defined term ``CAT Fees'' applies specifically to CAT fees related 
to Prospective CAT Costs. Id.
    \26\ See Notice, supra note 5, at 44910; see also proposed 
Section 11.3(b).
    \27\ See Notice, supra note 5, at 44921; see also proposed 
Section 11.3(b)(i)(C).
---------------------------------------------------------------------------

    For each category of fees, each CEBB and each CEBS will be required 
to pay a CAT fee for each such transaction in Eligible Securities in 
the prior month based on CAT Data.\28\ The CEBB's CAT fee or CEBS's CAT 
fee (as applicable) for each transaction in Eligible Securities will be 
calculated by multiplying the number of executed equivalent shares in 
the transaction by one-third and by the reasonably determined Fee 
Rate,\29\ as described below.\30\ Participants would incur CAT Fees 
only for Prospective CAT Costs and the Participant CAT Fee will be 
calculated by multiplying the number of executed equivalent shares in 
the transaction by one-third and by the reasonably determined Fee 
Rate.\31\ The Participants' one-third share of Historical CAT Costs and 
such other additional Past CAT Costs as reasonably determined by the 
Operating Committee will be paid by the cancellation of loans made to 
the Company on a pro rata basis based on the outstanding loan amounts 
due under the loans.\32\
---------------------------------------------------------------------------

    \28\ See Notice, supra note 5, at 44919; see also proposed 
Section 11.3(a)(iii), proposed Section 11.3(b)(iii).
    \29\ See Notice, supra note 5, at 44916-17 for the definition 
and description of the calculation of the Fee Rate.
    \30\ Id. at 44919; see also proposed Section 11.3(a)(iii), 
proposed Section 11.3(b)(iii).
    \31\ See Notice, supra note 5, at 44919; see also proposed 
Section 11.3(a)(ii).
    \32\ See proposed Section 11.3(b)(ii).
---------------------------------------------------------------------------

    As Plan Processor, FINRA CAT would be responsible for calculating 
the CAT fees and submitting invoices to the CAT Executing Brokers based 
on this CAT Data.\33\ All data used to calculate the fees under the 
Executed Share Model would be CAT Data, and, therefore, it would be 
available through the CAT for calculating CAT fees.\34\
---------------------------------------------------------------------------

    \33\ See Notice, supra note 5, at 44913.
    \34\ Id.
---------------------------------------------------------------------------

B. Calculation of Fees

1. CAT Budget
    Section 11.1(a) of the CAT NMS Plan describes the requirement for 
the Operating Committee to approve an operating budget for CAT LLC on 
an annual basis. It requires the budget to ``include the projected 
costs of the Company, including the costs of developing and operating 
the CAT for the upcoming year, and the sources of all revenues to cover 
such costs, as well as the funding of any reserve that the Operating 
Committee reasonably deems appropriate for prudent operation of the 
Company.''

[[Page 54440]]

    CAT LLC proposes to amend Section 11.1(a) of the CAT NMS Plan to 
require CAT LLC to determine costs for the operating budget for the CAT 
in a reasonable manner. CAT LLC proposes to add subparagraph (i) to 
Section 11.1(a) of the CAT NMS Plan to list the types of CAT costs to 
be included in the budget. Specifically, proposed Section 11.1(a)(i) of 
the CAT NMS Plan would state that ``[w]ithout limiting the foregoing, 
the reasonably budgeted CAT costs shall include technology (including 
cloud hosting services, operating fees, CAIS operating fees, change 
request fees and capitalized developed technology costs), legal, 
consulting, insurance, professional and administration, and public 
relations costs, a reserve, and such other categories as reasonably 
determined by the Operating Committee to be included in the budget.''
    CAT LLC also proposes to require the inclusion of five 
subcategories of technology costs in the budget: (1) cloud hosting 
services, (2) operating fees, (3) Customer and Account Information 
System (``CAIS'') operating fees, (4) change request fees, and (5) 
capitalized developed technology costs.\35\ CAT LLC states that it will 
consider the need to provide additional cost disclosure going 
forward.\36\
---------------------------------------------------------------------------

    \35\ CAT LLC states that breaking out technology costs in this 
manner is consistent with how such costs are broken out in the CAT 
budgets available on the CAT website. The CAT LLC budgets are 
available on the CAT website at <a href="https://www.catnmsplan.com/cat-financial-and-operating-budget">https://www.catnmsplan.com/cat-financial-and-operating-budget</a>. CAT LLC states that it currently 
does not propose to require the disclosure of additional 
subcategories of cost information, such as a further breakdown of 
the category of cloud hosting services into production costs, 
including linker costs and storage costs. Additionally, CAT LLC 
notes that the CAT NMS Plan requires that detailed cost information 
be made available to the Commission upon request, and detailed 
information on CAT costs and operations is regularly made available 
to the Commission staff and the Advisory Committee on a confidential 
basis. See Notice, supra note 5, at 44915.
    \36\ Id.
---------------------------------------------------------------------------

    CAT LLC proposes to add paragraph (ii) to Section 11.1(a) of the 
CAT NMS Plan, which provides that the budget will include an amount 
reasonably necessary to allow the Company to maintain a reserve of not 
more than 25% of the annual budget.'' In addition, proposed Section 
11.1(a)(ii) of the CAT NMS Plan would state that ``[f]or the avoidance 
of doubt, the calculation of the amount of the reserve would exclude 
the amount of the reserve from the budget.''
    CAT LLC proposes to provide additional information as to how budget 
surpluses would be treated for purposes of the reserve. Specifically, 
proposed subparagraph (ii) of Section 11.1(a) of the CAT NMS Plan would 
state that ``[t]o the extent collected CAT fees exceed CAT costs, 
including the reserve of 25% of the annual budget, such surplus will be 
used to offset future fees.'' In addition, CAT LLC further proposes to 
state in proposed Section 11.1(a)(ii) of the CAT NMS Plan that ``[f]or 
the avoidance of doubt, the Company will only include an amount for the 
reserve in the annual budget if the Company does not have a sufficient 
reserve (which shall be up to but not more than 25% of the annual 
budget).''
2. CAT Fees Related to Prospective CAT Costs
    CAT LLC proposes to describe the timing and method for calculating 
the Fee Rate for the CAT Fees related to Prospective CAT Costs in 
proposed Section 11.3(a)(i) of the CAT NMS Plan, and to provide 
additional detail regarding the Fee Rate in that provision. Proposed 
Section 11.3(a)(i) of the CAT NMS Plan would state that CAT Fees 
related to Prospective CAT Costs would be calculated twice a year, once 
at the beginning of the year and once during the year.
    Proposed Section 11.3(a)(i)(A)(I) of the CAT NMS Plan would provide 
that at the beginning of each year, the Operating Committee will 
calculate the Fee Rate by dividing the reasonably budgeted CAT costs 
for the year by the reasonably projected total executed equivalent 
share volume of all transactions in Eligible Securities for the year. 
Once the Operating Committee has approved such Fee Rate, the 
Participants shall be required to file with the Commission pursuant to 
Section 19(b) of the Exchange Act CAT Fees to be charged to Industry 
Members calculated using such Fee Rate. Participants and Industry 
Members will be required to pay CAT Fees calculated using this Fee Rate 
once such CAT Fees are in effect with regard to Industry Members in 
accordance with Section 19(b) of the Exchange Act.
    Proposed Section 11.3(a)(i)(A)(II) of the CAT NMS provides that 
during each year, the Operating Committee will calculate a new Fee Rate 
by dividing the reasonably budgeted CAT costs for the remainder of the 
year by the reasonably projected total executed equivalent share volume 
of all transactions in Eligible Securities for the remainder of the 
year. Once the Operating Committee has approved the new Fee Rate, the 
Participants shall be required to file with the Commission pursuant to 
Section 19(b) of the Exchange Act CAT Fees to be charged to Industry 
Members calculated using the new Fee Rate. Participants and Industry 
Members will be required to pay CAT Fees calculated using this new Fee 
Rate once such CAT Fees are in effect with regard to Industry Members 
in accordance with Section 19(b) of the Exchange Act.
    CAT LLC also proposes to add Section 11.3(a)(i)(A)(III) to the CAT 
NMS Plan to state that CAT Fees related to Prospective CAT Costs do not 
sunset automatically; such CAT Fees would remain in place until new CAT 
Fees are in place with a new Fee Rate. The Executed Share Model is 
designed to collect CAT fees continuously to provide uninterrupted 
revenue to pay CAT bills.\37\
---------------------------------------------------------------------------

    \37\ CAT LLC proposes to add proposed Section 11.3(a)(i)(A)(IV) 
to the CAT NMS Plan. This provision would state that ``[f]or the 
avoidance of doubt, the first CAT Fee may commence at the beginning 
of the year or during the year. If it were to commence during the 
year, the CAT Fee would be calculated as described in paragraph (II) 
of this Section.''
---------------------------------------------------------------------------

a. Budgeted CAT Costs
    The calculation of the Fee Rate for CAT Fees related to Prospective 
CAT Costs requires the determination of the budgeted CAT costs for the 
year or other relevant period. Proposed Section 11.3(a)(i)(C) of the 
CAT NMS Plan would state that the budgeted CAT costs for the year shall 
be comprised of all reasonable fees, costs and expenses reasonably 
budgeted to be incurred by or for the Company in connection with the 
development, implementation and operation of the CAT as set forth in 
the annual operating budget approved by the Operating Committee 
pursuant to Section 11.1(a) of the CAT NMS Plan, or as adjusted during 
the year by the Operating Committee.
b. Projected Total Executed Equivalent Share Volume
    The calculation of the Fee Rate for CAT Fees also requires the 
determination of the projected total executed equivalent share volume 
of transactions in Eligible Securities for each relevant period. 
Pursuant to proposed Section 11.3(a)(i)(D) of the CAT NMS Plan, each 
year, the Operating Committee would reasonably determine this 
projection based on the total executed equivalent share volume of 
transactions in Eligible Securities from the prior twelve months. As 
set forth in proposed Section 11.3(a)(iii)(B), Participants will be 
required to provide a description of the calculation of the projection 
in their fee filings pursuant to Section 19(b) of the Exchange Act. 
Furthermore, CAT LLC intends to calculate the CAT Fees based on a 
reasonable determination of the

[[Page 54441]]

projected total executed equivalent share volume of transactions in 
Eligible Securities.
c. Participant CAT Fees for Prospective CAT Costs
    CAT LLC proposes to add paragraph (A) to proposed Section 
11.3(a)(ii) of the CAT NMS Plan to describe the CAT Fee obligation of 
the Participants. Each Participant that is a national securities 
exchange will be required to pay the CAT Fee for each transaction in 
Eligible Securities executed on the exchange in the prior month based 
on CAT Data. Each Participant that is a national securities association 
will be required to pay the CAT Fee for each transaction in Eligible 
Securities executed otherwise than on an exchange in the prior month 
based on CAT Data. The CAT Fee for each transaction in Eligible 
Securities will be calculated by multiplying the number of executed 
equivalent shares in the transaction by one-third and by the Fee Rate 
determined pursuant to paragraph (a)(i) of Section 11.3.
    CAT LLC also proposes to include proposed paragraph (B) of proposed 
Section 11.3(a)(ii) of the CAT NMS Plan to clarify that Participants 
would only be required to pay CAT Fees when Industry Members are 
required to pay CAT Fees. Under the Executed Share Model, CAT Fees are 
designed to cover 100% of CAT costs by allocating costs between and 
among Participants and Industry Members. However, the CAT Fees charged 
to Participants are implemented via a different process than CAT Fees 
charged to Industry Members. CAT Fees charged to Participants are 
implemented via an approval of the CAT Fees by the Operating Committee 
in accordance with the requirements of the CAT NMS Plan. In contrast, 
CAT Fees charged to Industry Members may only become effective in 
accordance with the requirements of Section 19(b) of the Exchange Act.
d. Industry Member CAT Fees for Prospective CAT Costs
    CAT LLC proposes to describe the CAT Fees related to Prospective 
CAT Costs that would be charged to Industry Members in proposed Section 
11.3(a)(iii)(A) of the CAT NMS Plan. Each Industry Member that is the 
CEBB in a transaction in Eligible Securities and each Industry Member 
that is the CEBS in a transaction in Eligible Securities will be 
required to pay a CAT Fee for each such transaction in Eligible 
Securities in the prior month based on CAT Data. The CEBB's CAT Fee or 
CEBS's CAT Fee (as applicable) for each transaction in Eligible 
Securities will be calculated by multiplying the number of executed 
equivalent shares in the transaction by one-third and by the Fee Rate 
reasonably determined pursuant to paragraph (a)(i) of this Section 
11.3.
    Proposed Section 11.3(a)(iii)(B) of the CAT NMS Plan would require 
the fee filings to be made pursuant to Section 19(b) of the Exchange 
Act and Rule 19b-4 thereunder \38\ for Industry Member CAT Fees to 
include with regard to the CAT Fee: (A) the Fee Rate; (B) the budget 
for the upcoming year (or remainder of the year, as applicable), 
including a brief description of each line item in the budget; (C) a 
discussion of how the budget is reconciled to the collected fees; and 
(D) the projected total executed equivalent share volume of all 
transactions in Eligible Securities for the year (or remainder of the 
year, as applicable), and a description of the calculation of the 
projection. This detail would describe how the Fee Rate is calculated 
and explain how the budget used in the calculation is reconciled to the 
collected fees.\39\ In addition, in proposed Section 11.3(a)(iii)(B), 
CAT LLC proposes to state that the budgeted CAT costs described in the 
fee filings must provide sufficient detail to demonstrate that the CAT 
budget used in calculating the CAT Fees is reasonable and appropriate.

    \38\ CAT LLC expects the fee filings required to be made by the 
Participants pursuant to Section 19(b) of the Exchange Act with 
regard to CAT Fees to be filed pursuant to Section 19(b)(3)(A) of 
the Exchange Act and Rule 19b-(f)(2) thereunder. In accordance with 
Section 19(b)(3)(A) of the Exchange Act and Rule 19b-4(f)(2) 
thereunder, such fee filings would be effective upon filing.
    \39\ As a practical matter, the fee filing would provide the 
exact fee per executed equivalent share to be paid for the CAT Fees, 
by multiplying the Fee Rate by one-third and describing the relevant 
number of decimal places for the fee.
---------------------------------------------------------------------------

    The collection of CAT Fees from Industry Members is subject to 
Section 11.6 of the CAT NMS Plan regarding the Financial Accountability 
Milestones.\40\ Accordingly, CAT LLC proposes to state in proposed 
paragraph (C) to proposed Section 11.3(a)(iii) that Participants will 
not make fee filings pursuant to Section 19(b) of the Exchange Act 
regarding CAT Fees until the Financial Accountability Milestone related 
to Period 4 described in Section 11.6 of the CAT NMS Plan has been 
satisfied.
---------------------------------------------------------------------------

    \40\ On May 15, 2020, the Commission adopted amendments to the 
CAT NMS Plan designed to increase the Participants' financial 
accountability for the timely completion of the CAT (``Financial 
Accountability Amendments''). See Securities Exchange Act Release 
No. 88890, 85 FR 31322 (May 22, 2020). The Financial Accountability 
Amendments added Section 11.6 to the CAT NMS Plan to govern the 
recovery from Industry Members of any fees, costs, and expenses 
(including legal and consulting fees, costs and expenses) incurred 
by or for the Company in connection with the development, 
implementation and operation of the CAT from June 22, 2020 until 
such time that the Participants have completed Full Implementation 
of CAT NMS Plan Requirements (``Post-Amendment Expenses''). Section 
11.6 establishes target deadlines for four Financial Accountability 
Milestones (Periods 1, 2, 3 and 4) and reduces the amount of fee 
recovery available to the Participants if these deadlines are 
missed.
---------------------------------------------------------------------------

3. Historical CAT Assessment
    CAT LLC proposes to revise Section 11.3(b) of the CAT NMS Plan to 
provide that the Operating Committee will establish one or more 
Historical CAT Assessments to be payable by Industry Members with 
regard to Past CAT Costs.\41\
---------------------------------------------------------------------------

    \41\ CAT LLC states that, to date, there has been one Historical 
CAT Assessment (``Historical CAT Assessment 1''). See Notice, supra 
note 5, at 44920; Securities Exchange Act Release No. 100936 (Sept. 
5, 2024), 89 FR 74430 (Sept. 22, 2024) (BOX Exchange LLC filing for 
Historical CAT Assessment 1). The Participants state that there may 
be one or more Historical CAT Assessments related to CAT costs 
incurred prior to the completion of the fourth and final Financial 
Accountability Milestone, which CAT LLC states occurred in July 
2024. See Notice, supra note 5, at 44920.
---------------------------------------------------------------------------

    Proposed paragraph (A) of proposed Section 11.3(b)(i) of the CAT 
NMS Plan would state that the Operating Committee will calculate the 
Historical Fee Rate for each Historical CAT Assessment by dividing the 
Historical CAT Costs for each Historical CAT Assessment by the 
reasonably projected total executed equivalent share volume of all 
transactions in Eligible Securities for the Historical Recovery Period 
for each Historical CAT Assessment. Once the Operating Committee has 
approved such Historical Fee Rate, the Participants shall be required 
to file with the Commission pursuant to Section 19(b) of the Exchange 
Act such Historical CAT Assessment to be charged Industry Members 
calculated using such Historical Fee Rate. Industry Members will be 
required to pay such Historical CAT Assessment calculated using such 
Historical Fee Rate once such Historical CAT Assessment is in effect in 
accordance with Section 19(b) of the Exchange Act.
a. Historical CAT Costs
    Proposed Section 11.3(b)(i)(C) of the CAT NMS Plan would describe 
the Historical CAT Costs for calculating Historical CAT Assessments and 
would state that ``[t]he Operating Committee will reasonably determine 
the Historical CAT Costs sought to be recovered by each Historical CAT 
Assessment, where the Historical CAT Costs will be Past CAT Costs minus 
Past CAT Costs reasonably excluded from Historical CAT Costs by the 
Operating Committee.''

[[Page 54442]]

    CAT LLC proposes to further clarify the amount to be collected by 
the Historical CAT Assessments by adding a clarifying statement in 
proposed Section 11.3(b)(i)(C) that ``[e]ach Historical CAT Assessment 
will seek to recover from CAT Executing Brokers two-thirds of 
Historical CAT Costs incurred during the period covered by the 
Historical CAT Assessment.'' Each CEBS and CEBB pays one-third, and, 
therefore, two-thirds of the Historical CAT Costs would be collected 
from CAT Executing Brokers.
b. Historical Recovery Period
    Proposed Section 11.3(b)(i)(D)(I) of the CAT NMS Plan would 
describe the Historical Recovery Period used in calculating the 
Historical Fee Rate. This proposed provision would state that ``[t]he 
length of the Historical Recovery Period used in calculating each 
Historical Fee Rate will be reasonably established by the Operating 
Committee based upon the amount of the Historical CAT Costs to be 
recovered by the Historical CAT Assessment.'' This proposed provision, 
however, would state that ``no Historical Recovery Period used in 
calculating the Historical Fee Rate shall be less than 24 months or 
more than five years.'' \42\
---------------------------------------------------------------------------

    \42\ CAT LLC states that it used a Historical Recovery Period of 
two years for Historical CAT Assessment 1, which has a fee rate of 
$0.000013 per executed equivalent share. See Notice, supra note 5, 
at 44921; see also Securities Exchange Act Release No. 100936 (Sept. 
5, 2024), 89 FR 74430 (Sept. 22, 2024) (BOX Exchange LLC filing for 
Historical CAT Assessment 1).
---------------------------------------------------------------------------

    Under proposed Section 11.3(b)(i)(D)(II) of the CAT NMS Plan any 
Historical CAT Assessment would remain in effect until the relevant 
Historical CAT Costs are collected, whether that time is shorter or 
longer than the Historical Recovery Period used in calculating the 
Historical Fee Rate.
c. Projected Total Executed Equivalent Share Volume
    The Historical Fee Rate for a Historical CAT Assessment would be 
calculated by using the projected total executed equivalent share 
volume of all transactions in Eligible Securities for the Historical 
Recovery Period for such Historical CAT Assessment. As set forth in 
proposed Section 11.3(b)(i)(E) of the CAT NMS Plan, ``[t]he Operating 
Committee shall reasonably determine the projected total executed 
equivalent share volume of all transactions in Eligible Securities for 
each Historical Recovery Period based on the executed equivalent share 
volume of all transactions in Eligible Securities for the prior twelve 
months.'' In addition, CAT LLC proposes to allow the Operating 
Committee to base its projection on the prior twelve months, but to use 
its discretion to analyze the likely volume for the upcoming year. As 
set forth in proposed Section 11.3(b)(iii)(B)(II) of the CAT NMS Plan, 
Participants will be required to provide a description of the 
calculation of the projection in their fee filings pursuant to Section 
19(b) of the Exchange Act for Historical CAT Assessments.
d. Past CAT Costs and Participants
    Proposed Section 11.3(b)(ii) of the CAT NMS Plan would clarify that 
the Participants would not be required to pay the Historical CAT 
Assessment as the Participants previously have paid all Past CAT Costs. 
In addition, proposed Section 11.3(b)(ii) of the CAT NMS Plan would 
state that ``[i]n lieu of a Historical CAT Assessment, the 
Participants' one-third share of Historical CAT Costs and such other 
additional Past CAT Costs as reasonably determined by the Operating 
Committee will be paid by the cancellation of loans made to the Company 
on a pro rata basis based on the outstanding loan amounts due under the 
loans.'' Furthermore, proposed Section 11.3(b)(ii) of the CAT NMS Plan 
would emphasize that ``[t]he Historical CAT Assessments are designed to 
recover two-thirds of the Historical CAT Costs.''
e. Historical CAT Assessment for Industry Members
    CAT LLC proposes to describe the Historical CAT Assessment charged 
to Industry Members in proposed Section 11.3(b)(iii)(A) of the CAT NMS 
Plan. Each month in which a Historical CAT Assessment is in effect, 
each CEBB and each CEBS shall pay a fee for each transaction in 
Eligible Securities executed by the CEBB or CEBS from the prior month 
as set forth in CAT Data, where the Historical CAT Assessment for each 
transaction will be calculated by multiplying the number of executed 
equivalent shares in the transaction by one-third and by the Historical 
Fee Rate reasonably determined pursuant to paragraph (b)(i) of this 
Section 11.3.
    CAT LLC proposes to provide additional details regarding the fee 
filings to be filed by the Participants regarding each Historical CAT 
Assessment pursuant to Section 19(b) of the Exchange Act in proposed 
Section 11.3(b)(iii)(B) of the CAT NMS Plan.\43\ Specifically, CAT LLC 
proposes to state that each Participant will be required to file a fee 
filing pursuant to Section 19(b) of the Exchange Act to describe each 
Historical CAT Assessment.\44\
---------------------------------------------------------------------------

    \43\ CAT LLC expects the fee filings required to be made by the 
Participants pursuant to Section 19(b) of the Exchange Act with 
regard to Historical CAT Assessments to be filed pursuant to Section 
19(b)(3)(A) of the Exchange Act. In accordance with Section 
19(b)(3)(A) of the Exchange Act, fee filings made pursuant to 
Section 19(b)(3)(A) of the Exchange Act would be effective upon 
filing.
    \44\ See proposed Section 11.3(b)(iii)(B)(I).
---------------------------------------------------------------------------

    CAT LLC also proposes to provide additional detail about the 
information that Participants would be required to include in their fee 
filings to be made pursuant to Section 19(b) of the Exchange and Rule 
19b-4(f)(2) for Historical CAT Assessments in proposed paragraph 
(b)(iii)(B)(II) of proposed Section 11.3 of the CAT NMS Plan. 
Specifically, such filings would be required to include: (A) the 
Historical Fee Rate; (B) a brief description of the amount and type of 
Historical CAT Costs, including (1) the technology line items of cloud 
hosting services, operating fees, CAIS operating fees, change request 
fees and capitalized developed technology costs, (2) legal, (3) 
consulting, (4) insurance, (5) professional and administration, and (6) 
public relations costs; (C) the Historical Recovery Period and the 
reasons for its length; and (D) the projected total executed equivalent 
share volume of all transactions in Eligible Securities for the 
Historical Recovery Period, and a description of the calculation of the 
projection.\45\ In addition, CAT LLC proposes to clarify in proposed 
Section 11.3(b)(iii)(B)(II) that the Historical CAT Costs described in 
the fee filings must provide sufficient detail to demonstrate that such 
costs are reasonable and appropriate.
---------------------------------------------------------------------------

    \45\ As a practical matter, the fee filing would provide the 
exact fee per executed equivalent share to be paid for the 
Historical CAT Assessment, by multiplying the Historical Fee Rate by 
one-third and describing the relevant number of decimal places for 
the fee.
---------------------------------------------------------------------------

    The collection of Historical CAT Assessments from Industry Members 
is subject to Section 11.6 of the CAT NMS Plan regarding the Financial 
Accountability Milestones. Accordingly, CAT LLC proposes to clarify in 
proposed Section 11.3(b)(iii)(B)(III) that Participants will not make 
CAT fee filings pursuant to Section 19(b) of the Exchange Act regarding 
a Historical CAT Assessment until any applicable Financial 
Accountability Milestone has been satisfied.
4. Participant Pass-Through Fees
    CAT LLC proposes to add a new paragraph (e) to Section 11.3 of the 
CAT NMS Plan to state that each Participant agrees not to file with the 
SEC a proposed rule change pursuant to

[[Page 54443]]

Section 19(b)(4) and Rule 19b-4 thereunder that would establish a new 
fee for passing through to its members the CAT fee charged to such 
Participant in accordance with Section 11.3(a). The proposed amendment 
does not address whether Industry Members may pass-through their CAT 
fees to their customers.

C. CAT Fee Schedule for Participants

    To implement the Participant CAT fees, CAT LLC proposes to add a 
fee schedule, entitled ``Consolidated Audit Trail Funding Fees,'' to 
Appendix B of the CAT NMS Plan. Proposed paragraph (a) of the fee 
schedule would describe the CAT Fees to be paid by the Participants 
under the Executed Share Model. Specifically, paragraph (a) of the 
Participant fee schedule would state that ``[e]ach Participant shall 
pay the CAT Fee set forth in Section 11.3(a) of the CAT NMS Plan to 
Consolidated Audit Trail, LLC in the manner prescribed by Consolidated 
Audit Trail, LLC on a monthly basis based on the Participant's 
transactions in Eligible Securities in the prior month.''

IV. Summary of Comments

A. Allocation of Fee Among Participants and Industry Members

    Under the Executed Share Model, CAT fees would be allocated one-
third to the applicable Participant, one-third to the CEBS and one-
third to the CEBB of a transaction. Two commenters oppose the proposed 
allocation.\46\

---------------------------------------------------------------------------

    One commenter states that once analyzed by the Commission, ``it 
will be clear'' that allocating at least two-thirds of CAT system costs 
to broker-dealers and their customers in the manner contemplated by the 
Proposed Amendment is not fair and equitable under the Exchange 
Act.\47\ The commenter states that the Commission must also consider 
the economic implications of the ``winners and losers'' in terms of the 
proposed allocation of costs, including an undue impact on equities 
(versus options), as well as an undue impact on retail investors and 
market makers--market participants that will be responsible for a 
disproportionate percentage of CAT costs.\48\

    \48\ Id. at 6-7.
---------------------------------------------------------------------------

    The other commenter states that, while the Proposed Amendment 
justified the fairness of the Executed Share Model by stating that CAT 
would operate like other fees, such as FINRA's trading activity fee 
(``TAF''), Section 31 fees, and the options regulatory fee, the 
Proposed Amendment did not support why those other fees should be used 
as a model in this context.\49\ For example, the commenter states that 
the TAF is designed to recover the costs of FINRA's regulatory 
activities, while the CAT fees are intended to align with the costs to 
build, operate and administer the CAT.\50\ Further, the commenter 
states that the Proposed Amendment insufficiently explains the 
connection between the TAF and CAT fees because CAT LLC focuses solely 
on their ``superficial connection'' as fees that are transaction-based 
fees intended to provide funding for regulatory costs.\51\ The 
commenter states that ``CAT LLC's observations superficially focus on 
the fact that these fees also use transaction-based metrics (and may be 
assessed on members) and neglects other factors relevant to the 
analysis including, for example, that these fees are used in 
combination with other funding mechanisms and metrics to support an 
overall funding framework.'' \52\

    \49\ See FINRA June 2022 Letter at 4.
    \50\ See FINRA April 2023 Letter at 8.
    \51\ Id. The commenter also states that ``it is unclear how 
assessing on FINRA the largest allocation of the SRO portion of CAT 
expenses `provides funding for regulatory costs' in any reasonable 
and equitable sense comparable to the TAF. . .'' Id.
    \52\ See FINRA May 2023 Letter at 3.
---------------------------------------------------------------------------

    This commenter also argues that the Proposed Amendment did not 
justify why the proposed allocation by thirds to the Participant, buy-
side and sell-side is equitable in the context of the CAT NMS Plan.\53\ 
The commenter argues that the Proposed Amendment does not consider 
alternatives suggested by commenters on a prior proposed funding 
model,\54\ such as a model similar to Section 31 fees and a CAT funding 
model based on the ``Cost Recovery Principle'' and the ``Benefits 
Received Principle,'' and that the Participants have not ``meaningfully 
analyzed'' the suggested alternatives in the Proposed Amendment.\55\

---------------------------------------------------------------------------

B. Executed Equivalent Shares

a. Executed Equivalent Share Volume
    One commenter argues that the Proposed Amendment does not explain 
why the use of executed share volume as the basis of the cost 
allocation methodology, instead of message traffic, is equitable.\56\ 
The commenter explains that in prior models, message traffic was the 
key proxy for cost generation used to align CAT fees with CAT costs, 
but the Executed Share Model would base its cost allocation methodology 
entirely on executed share volume.\57\ The commenter states that the 
Participants' argument that executed share volume is related to cost 
generation is not enough to demonstrate that its use is reasonable and 
equitable.\58\ This commenter further states that the Executed Share 
Model is inconsistent with the ``cost alignment'' funding principle in 
Section 11.2(b) of the CAT NMS Plan, which requires the Participants to 
seek to establish an allocation of costs that takes into account 
distinctions in the securities trading operations of Participants and 
Industry Members and their relative impact upon Company resources and 
operations.\59\ The commenter states that ``the Proposal fails to 
establish a sufficient nexus between executed share volume and the 
technology burdens that generate CAT costs and fails to relate each 
reporter group's allocation to the burden that each reporter group 
imposes on CAT.'' \60\
---------------------------------------------------------------------------

    \56\ See FINRA June 2022 Letter at 3. See also Citadel Letter at 
6-7 (noting that the Proposed Amendment allocates CAT costs based on 
executed shares, which may particularly impact retail investors 
given the amount of retail trading in low-priced NMS stocks).

    \60\ See FINRA June 2022 Letter at 4.
---------------------------------------------------------------------------

    The same commenter expresses concerns regarding CAT LLC's support 
for the elimination of the requirement that, when establishing the 
funding of the CAT, the Operating Committee must take into account 
``distinctions in the securities trading operations of Participants and 
Industry Members and their relative impact upon Company resources and 
operations.'' \61\ This

[[Page 54444]]

commenter states that the Proposed Amendment ``seeks to amend the core 
funding principles to align with an unjustified allocation 
methodology.'' \62\ The commenter states that any changes to the 
funding principles ``must be well-reasoned and transparent and must 
continue to support the achievement of a fair and equitable outcome.'' 
\63\
---------------------------------------------------------------------------

    \61\ See FINRA June 2022 Letter at 4; see also FINRA April 2023 
Letter at 7.
    \62\ See FINRA June 2022 Letter at 4. The commenter states that 
the Executed Share Model instead places the greatest emphasis on the 
funding principle relating to the ``ease of billing and other 
administrative functions,'' favoring that principle over cost 
alignment. Id. at 5.
    \63\ Id.; FINRA April 2023 Letter at 8-9.
---------------------------------------------------------------------------

    Additionally, the commenter objects to the statement in the 
Proposed Amendment that ``trading activity provides a reasonable proxy 
for cost burden on the CAT, and therefore is an appropriate metric for 
allocating CAT costs among CAT Reporters.'' \64\ The commenter states 
that this statement is inconsistent with information that demonstrates 
that volume from FINRA trade reporting facilities (``TRFs'') contribute 
``a very small percentage of annual CAT compute and storage costs.'' 
\65\ The commenter states that as a result, it cannot support the 
Participants' assertion that trading activity is a reasonable proxy for 
cost burden.\66\ The commenter states that the Proposed Amendment 
``fails to provide for reasonable fees that are equitably allocated and 
not unfairly discriminatory, does not reflect a reasonable approach to 
allocating costs amongst the Participants, nor does it transparently or 
accurately present information regarding the true sources of cost 
burdens on the CAT.'' \67\

---------------------------------------------------------------------------

b. FINRA Allocation
    One commenter objects to the proposed allocation of Participant CAT 
fees to FINRA.\68\ This commenter objects to the allocation to FINRA of 
the total CAT costs to be borne by the Participants, stating that the 
Proposed Amendment acknowledges that FINRA would be forced to bear a 
disproportionate share of CAT costs.\69\ The commenter states that the 
Proposed Amendment does not grapple with the implications of these 
costs, particularly given FINRA''s status as a non-profit, member-
funded national securities association.\70\ The commenter also states 
that FINRA's allocation would largely be based on transaction volume 
reported to the TRF; however, the commenter states that TRF 
transactions generate fewer costs for the CAT,\71\ as opposed to 
options activity, but that only 25% of total Participant CAT fees would 
be assessed for options activity, while the remaining 75% would be 
assessed for equities activity.\72\
---------------------------------------------------------------------------

    \68\ See FINRA October 2025 Letter; FINRA May 2023 Letter; FINRA 
April 2023 Letter; FINRA June 2022 Letter.
    \69\ See FINRA October 2025 Letter at 4, 6-7; see also FINRA May 
2023 Letter at 2; FINRA April 2023 Letter at 3.
    \70\ See FINRA October 2025 Letter at 6-7. See also FINRA April 
2023 Letter at 3; FINRA June 2022 Letter at 6. The commenter has 
previously stated that FINRA's share was more than double that of 
the next highest Participant and $4 million more than all option 
exchanges combined. See FINRA April 2023 Letter at 4; see also FINRA 
June 2022 Letter at 5.
    \71\ See FINRA April 2023 Letter at 8, n.23.
    \72\ Id.; FINRA May 2023 Letter at 2.
---------------------------------------------------------------------------

    The commenter argues that, unlike the exchange Participants, 
transactions are not executed on a FINRA marketplace and FINRA does not 
receive commercial revenue for those transactions.\73\ The commenter 
explains that FINRA does not currently directly receive fees from its 
TRFs for listed stocks that would cover CAT costs, because each FINRA 
TRF is operated by an exchange business member that retains the trade 
reporting and market data revenues generated by TRFs, subject to 
certain payments to FINRA for agreed-upon costs.\74\ Thus, the 
commenter states that exchanges have direct revenue streams from the 
operation of facilities on which the transactions that are taxed using 
the Executed Share Model occur, whereas FINRA generally does not retain 
such revenue for over-the-counter transactions in listed 
securities.\75\ The commenter also states that FINRA members can report 
over-the-counter transactions in listed stocks to the FINRA Alternative 
Display Facility, although most transactions are reported to a TRF.\76\

---------------------------------------------------------------------------

    The commenter further states that FINRA cannot necessarily recoup 
its costs through regulatory services agreements (``RSAs'') that the 
commenter has entered into with various exchanges because these are 
voluntary commercial contracts that are not and cannot be reasonably 
viewed as a reliable source of sustainable CAT funding sufficient to 
replace membership fees at the levels required by the Executed Share 
Model.\77\ Additionally, the commenter questions CAT LLC's statement 
that the Proposed Amendment ``reflects a reasonable effort to allocate 
costs based on the extent to which different CAT Reporters participate 
in and benefit from the equities and options markets.'' \78\ 
Specifically, the commenter asks how CAT LLC's statement explains the 
size of FINRA's allocation \79\ and notes that this statement 
``conflates the costs to create and operate the CAT with the usage of 
CAT data.'' \80\

---------------------------------------------------------------------------

    This commenter also expresses concern about alleged arbitrary 
treatment of FINRA by the other Participants of the CAT NMS Plan.\81\ 
This commenter believes that FINRA's ``outsized allocation'' \82\ was 
because of its limited voting power, only having one out of 25 votes on 
the Operating Committee as it does not control, nor is under common 
control with, any other Participant.\83\ This commenter states that it 
is critical for the Commission to consider the differences among 
Participants and the inevitable impact on FINRA members of any cost 
allocation to FINRA.\84\

---------------------------------------------------------------------------

C. Pass-Through Prohibition

    Two commenters state that the Proposed Amendment exceeds CAT LLC's 
authority and is unlawful, because the Exchange Act and Rule 608 of 
Regulation NMS do not empower CAT LLC or the Plan Participants to 
restrict fee filings made by other Plan Participants or control how 
other Plan Participants internally fund their costs.\85\ One commenter 
states that both the text and history of Rule 608's predecessor 
establishes that Rule 608's scope of fee authority is limited to joint 
fees for NMS plans.\86\ This commenter states that the proposed pass-
through provision would not control CAT LLC fees, but instead purport 
to control how a Participant SRO funds its own SRO costs through 
separate SRO fees, which could potentially establish a dangerous

[[Page 54445]]

precedent and enable similar overreach in other NMS plans.\87\
---------------------------------------------------------------------------

violate FINRA's due process rights and run afoul of the Takings 
Clause. Id. at 10.
---------------------------------------------------------------------------

    Two commenters object to the language of the Proposed Amendment and 
proposed provisions insofar as it states each Participant agrees not to 
file with the SEC rule change(s) a new fee for passing through to its 
members the CAT fee charged to such Participant.\88\ One commenter 
states that while it would contemplate agreeing not to file new fees 
for passing through SRO CAT costs under certain conditions, it has not 
yet done so and did not agree to do so under the terms of the Proposed 
Amendment.\89\ The other commenter states that the Proposed Amendment 
is ``factually incorrect'' because it purports to reflect an agreement 
by the commenter and each CAT Plan Participant to refrain from 
establishing certain fees, which the commenter did not agree to.\90\

    \89\ See FINRA October 2025 Letter at 10.
    \90\ See Cboe Letter at 2.
---------------------------------------------------------------------------

    Multiple commenters state that the proposed language that would 
prohibit pass-through fees by the Participants would be ineffective in 
its stated goal.\91\ Three commenters specifically note that the 
provision only purports to prevent a Participant from filing a rule 
change with the Commission to establish a ``new fee.'' \92\ One of 
these commenters states that this usage of the term ``new fee'' raises 
the specter of adding CAT costs to existing fees the SROs already 
charge their members to recoup their CAT costs, thus doing indirectly 
what they cannot do directly. Another commenter notes that this 
theoretical limit on pass-through fees also ignores the reality of 
FINRA's funding structure, because the most direct way to allocate 
FINRA's designated CAT costs to its members (who ultimately will bear 
costs allocated to FINRA) would be to apply cost recovery fees to 
members whose activities most directly contribute to FINRA's designated 
portion of Participant CAT fees.\93\ Another commenter states that CAT 
LLC is ``clearly'' attempting to preserve the ability for SROs to pass 
through some of all of their CAT costs to their members in other ways 
in direct contravention of the Eleventh Circuit's decision.\94\ This 
commenter states that allowing SRO pass-throughs directly conflicts 
with the Eleventh Circuit's decision and fundamentally alters the 
allocation formula that the Commission is considering.\95\ Another 
commenter states that FINRA is responsible for roughly 10% of the 
entire CAT budget, and nothing in the Proposed Amendment stops FINRA 
from passing on 100% of those costs to its members by increasing its 
existing membership fees.\96\ Two commenters state that the Proposed 
Amendment is simply an attempt to circumvent the Eleventh Circuit's 
opinion vacating the 2023 Funding Model Order, and that the Proposed 
Amendment should be disapproved.\97\

also Citadel Letter at 9 (stating that the Proposed Amendment 
provides no explanation as to how FINRA, as a not-for-profit-
organization, will fund its allocation of CAT costs, which amounts 
to more than 10% of the entire CAT budget).

Christopher A. Iacovella, President & Chief Executive Officer, 
American Securities Association, dated October 31, 2025 (``ASA 
Letter'') at 1-2 (stating that the Proposed Amendment ``mirrors the 
unlawful 2023 plan in every essential respect'').
---------------------------------------------------------------------------

D. Other Comments

a. Lack of Industry Input
    Commenters state that the Proposed Amendment lacks input from the 
industry.\98\ One commenter states that the SROs through the CAT 
Operating Committee have for years sought to establish a funding model 
for CAT without meaningful industry input, including the Proposed 
Amendment which was filed without prior consultation with Industry 
Members.\99\ One commenter states that the Commission must conduct a 
``complete and comprehensive analysis of every CAT-related cost,'' 
including an examination of how broker-dealer financial 
responsibilities were determined, and produce a public report detailing 
the findings of this audit.\100\ Another commenter recommends 
engagement of a third-party technology firm to perform an independent 
review of the technological design of CAT to identify opportunities to 
optimize and reduce costs.\101\
---------------------------------------------------------------------------

    \98\ See, e.g., SIFMA October 2025 Letter at 3. See also FINRA 
June 2022 Letter at 8, 9 (advocating for a more inclusive 
development process that would include input from the industry).
    \99\ See SIFMA October 2025 Letter at 3; supra note 17.
    \100\ See ASA Letter at 3.
    \101\ See Citadel Letter at 13.
---------------------------------------------------------------------------

b. Rule 613 and the CAT NMS Plan
    Two commenters state that the Proposed Amendment is unlawful 
because the CAT itself is unlawful.\102\ These commenters state that no 
federal statute authorizes the creation of CAT and that the lack of 
statutory authority to create the CAT means the Commission necessarily 
lacks the authority to compel broker-dealers to fund CAT.\103\ One 
commenter states that the 2023 Funding Model Order fails to identify 
any statutory authority explicitly granting the Commission the power to 
create the CAT.\104\ One commenter further asserts that it is unlawful 
for the Commission to outsource the funding of the CAT as to 
effectively immunize it from congressional appropriations or oversight, 
amounting to an ``end-run'' that turns the Appropriations Clause on its 
head by permitting an executive branch agency to fund its own 
regulatory initiatives through outsourcing taxing authority to the 
SROs.\105\
---------------------------------------------------------------------------

    \102\ See Citadel Letter at 2; AmFree Letter at 1-2.
    \103\ See Citadel Letter at 2; AmFree Letter at 1-2 (stating 
that the CAT exceeds the Commission's statutory authority).
    \104\ See Citadel Letter at 2. See also AmFree Letter at 1 
(stating that the Commission has conceded that Congress has never 
provided ``express authorization for CAT,'' and that agencies 
require ``clear congressional authorization'' before making ``major 
policy decisions'' on matters of vast public significance such as 
the ones here).
    \105\ See Citadel Letter at 3.
---------------------------------------------------------------------------

    Another commenter asserts that the CAT has violated the 
constitutional right to privacy for millions of Americans, and asks the 
Commission to undertake an analysis as to whether any system that looks 
like the current CAT is consistent with existing law, and if so, any 
funding mechanism must be consistent with the appropriations clause of 
the Constitution and not rely entirely on fees from broker-dealers and 
their customers.\106\
---------------------------------------------------------------------------

    \106\ See ASA Letter at 2-3.
---------------------------------------------------------------------------

c. Economic Analysis
    One commenter states that the Proposed Amendment does not address 
concerns regarding the economic analysis used in the 2023 Funding 
Amendment Approval, stating that the Participants fail to provide any 
updated data that the Commission must obtain and assess to conduct its 
analysis,

[[Page 54446]]

including, among other things, the current and future trajectory of the 
CAT budget, broker-dealer CAT reporting costs, and the impact of the 
proposed funding model.\107\ Another commenter notes that while it is 
the Commission's responsibility, independent of the SROs, to weigh the 
costs and benefits of the Proposed Amendment and determine its impact 
on efficiency, competition, and capital formation, that the Commission 
should require the SROs to provide necessary data.\108\ Another 
commenter states that the Proposed Amendment does not address how 
FINRA's collection and payment of CAT fees will affect efficiency, 
competition, and capital formation.\109\
---------------------------------------------------------------------------

    \107\ See SIFMA October 2025 Letter at 2.
    \108\ See Citadel Letter at 4. This commenter states that in its 
review, among other things, the Commission must address the current 
CAT budget, the inaccuracy of 2016 cost estimates, updated estimates 
of the future trajectory of the CAT budget, broker-dealer reporting 
costs, electronic blue sheet costs, and the industry's allocation of 
CAT operational costs. Id. at 4-7. In addition, the commenter states 
that the Commission must consider the economic implications of the 
proposed allocation methodology's undue impact on equities (versus 
options), undue impact on retail investors, and undue impact on 
market makers. Id. at 6-7.
    \109\ See AmFree Letter at 6.
---------------------------------------------------------------------------

d. Rule 608 of Regulation NMS and Rule 19b-4
    One commenter states that the Proposed Amendment is unlawful 
because it does not include any detail regarding actual CAT costs that 
will be allocated to broker-dealers and instead relies on future 
filings made by each SRO pursuant to Commission Rule 19b-4.\110\ This 
commenter states that this unlawfully circumvents Rule 608 of 
Regulation NMS, which states that fee filings relating to an NMS Plan 
cannot be filed as immediately effective, and instead must be approved 
by the Commission prior to becoming effective.\111\ In addition, the 
commenter states that the Commission must assess whether the actual 
costs that may be allocated are fair and reasonable because post hoc 
review of fee filings is insufficient.\112\
---------------------------------------------------------------------------

    \110\ See Citadel Letter at 10.
    \111\ Id.
    \112\ Id. at 11. The commenter states that historical CAT costs 
and the current CAT budget are known right now, and the Commission 
must determine whether those costs are reasonable to recoup. Id.
---------------------------------------------------------------------------

e. Alternatives to the Proposed Amendment
    Two commenters suggest that the Commission should consider a 
``time-limited interim funding solution'' instead of approving the 
Proposed Amendment.\113\ Two other commenters state that the Proposed 
Amendment should be abandoned in favor of a new CAT funding approach 
involving the fee process in Section 31 of the Exchange Act.\114\ One 
commenter states that in addition to being required by law, for the 
first time there will be meaningful checks and balances as part of the 
governance process and the Commission will be incentivized to carefully 
oversee the size of the CAT budget and carefully weigh the costs and 
benefits of required functionality, while Congress will have a clear 
role in order to protect against waste and regulatory overreach.\115\ 
The other commenter states that this approach would better align 
incentives to control costs, address longstanding concerns about 
ineffective governance, and subject CAT to the checks and balances of 
the appropriations process for the SEC.\116\
---------------------------------------------------------------------------

    \113\ See Cboe Letter at 2. Cboe states that in connection with 
an interim funding model, that Cboe is open to discussing a 
voluntary agreement by all of the SROs not to make rule filings 
seeking to pass through their CAT costs for a specified period 
(e.g., one year). Cboe Letter at 2.

5.
    \115\ See Citadel Letter at 13.
    \116\ See SIFMA October 2025 Letter at 4-5.
---------------------------------------------------------------------------

f. Financial Accountability Milestones
    The Participants are not permitted to recoup CAT costs from broker-
dealers and their customers until a series of Financial Accountability 
Milestones are met, and one commenter states that the Commission must 
independently validate SRO assertions regarding various dates by which 
they assert that specific Financial Accountability Milestones were 
met.\117\ The commenter states that the SROs assert that ``Full 
Implementation of CAT NMS Plan Requirements'' was achieved in July 
2024, but that this is in reliance on various exemptive orders issued 
by the Commission.\118\ In addition, the commenter states that belated 
exemptive relief cannot retroactively bring the SROs into compliance 
with an earlier Financial Accountability Milestone, which would mean no 
historical fees could be collected.\119\
---------------------------------------------------------------------------

    \117\ See Citadel Letter at 11-13. The commenter states that the 
Proposed Amendment provides the only opportunity for the Commission 
to scrutinize and clearly document SRO compliance with the Financial 
Accountability Milestones. Id. at 12.
    \118\ Id. at 12.
    \119\ Id. at 12-13.
---------------------------------------------------------------------------

g. Comprehensive Review of the CAT
    Multiple commenters reference a ``comprehensive review'' of the CAT 
that was initiated by the Chairman of the Commission, which includes 
consideration of mechanisms to address CAT costs.\120\ One commenter 
states that rushing to adopt the Proposed Amendment would front-run the 
outcome of the comprehensive CAT review initiated by the Chairman and 
prevents a full evaluation of cost allocation in line with the Eleventh 
Circuit's decision.\121\ One commenter suggests that the Commission 
should allocate its limited resources to implement the call for a 
comprehensive review and to chart a new path forward, rather than 
becoming embroiled in yet another controversy over the funding of a 
``broken system.'' \122\ Another commenter states that the 
comprehensive review of the CAT, ``is the only rational path forward to 
ending the constant escalation of implementation costs.'' \123\ Other 
commenters were positive regarding the comprehensive review.\124\

Atkins, May 19, 2025, available at <a href="https://www.sec.gov/newsroom/speeches-statements/atkins-prepared-remarks-sec-speaks-051925">https://www.sec.gov/newsroom/speeches-statements/atkins-prepared-remarks-sec-speaks-051925</a>.

    \123\ See ASA Letter at 2.
    \124\ See SIFMA October 2025 Letter at 4 (looking forward to 
further engagement to reduce CAT costs as well as on other 
significant CAT reforms the Commission should consider); AmFree 
Letter at 1 (stating that the commenter appreciates a comprehensive 
review that examines not only the system's staggering costs, but 
also its overbroad scope and onerous requirements); Citadel Letter 
at 1 (noting that current Commission leadership ``has rightly 
indicated that a new course must be charted'').
---------------------------------------------------------------------------

h. Previously Collected Fees From Broker-Dealers
    One commenter states that the Proposed Amendment does not mention 
the millions of dollars of extra fees that broker-dealers and their 
customers ``were unlawfully compelled to pay to FINRA under the 2023 
funding order as an explicit SRO pass-through,'' and that these 
unlawful payments must be accounted for in any funding model.\125\ 
Another commenter states that the Commission should consider 
reimbursing broker-dealers for funds they have collectively been forced 
to contribute to the CAT, and provides a list of possible mechanisms 
for reimbursement including direct reimbursement from a Commission 
administered fund, an offset or waiver or other regulatory fees, or 
Congressional appropriations.\126\
---------------------------------------------------------------------------

    \125\ See Citadel Letter at 10.
    \126\ See ASA Letter at 3-4.
---------------------------------------------------------------------------

i. FINRA Constitutionality
    One commenter argues that FINRA's regulatory authority over broker-
dealers is unconstitutional, either because FINRA violates the private 
non-delegation doctrine as a private entity, or the Appointments Clause 
if FINRA is

[[Page 54447]]

considered a government entity.\127\ This commenter states that the 
constitutional problems with FINRA require rejecting the Proposed 
Amendment for a number of reasons, including that the Proposed 
Amendment depends on the authority and involvement of an unlawful 
entity, including FINRA's role in the operation of CAT and calculation 
of proposed fees, and the probability that at least one court will hold 
FINRA to be unlawful.\128\
---------------------------------------------------------------------------

    \127\ See AmFree Letter at 2-4.
    \128\ Id. at 4-6.
---------------------------------------------------------------------------

V. Proceedings To Determine Whether To Approve or Disapprove the 
Proposed Amendment

    The Commission is instituting proceedings pursuant to Rule 
608(b)(2)(i) of Regulation NMS,\129\ and Rules 700 and 701 of the 
Commission's Rules of Practice,\130\ to determine whether to disapprove 
the Proposed Amendment or to approve the Proposed Amendment with any 
changes or subject to any conditions the Commission deems necessary or 
appropriate. The Commission is instituting proceedings to have 
sufficient time to consider the complex issues raised by Proposed 
Amendment, including comments received. Institution of proceedings does 
not indicate that the Commission has reached any conclusions with 
respect to any of the issues involved. Rather, the Commission seeks and 
encourages interested persons to provide additional comment on the 
Proposed Amendment to inform the Commission's analysis.

---------------------------------------------------------------------------

    Rule 608(b)(2) of Regulation NMS provides that the Commission 
``shall approve a national market system plan or proposed amendment to 
an effective national market system plan, with such changes or subject 
to such conditions as the Commission may deem necessary or appropriate, 
if it finds that such plan or amendment is necessary or appropriate in 
the public interest, for the protection of investors and the 
maintenance of fair and orderly markets, to remove impediments to, and 
perfect the mechanisms of, a national market system, or otherwise in 
furtherance of the purposes of the Exchange Act.'' \131\ Rule 608(b)(2) 
further provides that the Commission shall disapprove a national market 
system plan or proposed amendment if it does not make such a 
finding.\132\ In the Notice, the Commission sought comment on the 
Proposed Amendment, including whether the Proposed Amendment is 
consistent with the Exchange Act.\133\ In this order, pursuant to Rule 
608(b)(2)(i) of Regulation NMS,\134\ the Commission is providing notice 
of the grounds for disapproval under consideration:

Proposed Amendment is necessary or appropriate in the public interest, 
for the protection of investors and the maintenance of fair and orderly 
markets, to remove impediments to, and perfect the mechanisms of, a 
national market system, or otherwise in furtherance of the purposes of 
the Exchange Act;
    <bullet> Whether the Participants have demonstrated how the 
Proposed Amendment is consistent with Section 6(b)(4) \135\ and Section 
15A(b)(5),\136\ of the Exchange Act, which require that the rules of a 
national securities exchange ``provide for the equitable allocation of 
reasonable dues, fees, and other charges among its members and issuers 
and other persons using its facilities'' and that the rules of a 
national securities association ``provide for the equitable allocation 
of reasonable dues, fees, and other charges among members and issuers 
and other persons using any facility or system which the association 
operates or controls;''

Proposed Amendment is consistent with Section 6(b)(5) \137\ and Section 
15A(b)(6),\138\ of the Exchange Act, which require that the rules of a 
national securities exchange or national securities association 
``promote just and equitable principles of trade. . . protect investors 
and the public interest; and [to be] not designed to permit unfair 
discrimination between customers, issuers, brokers, or dealers;''

    Under the Commission's Rules of Practice, the ``burden to 
demonstrate that a NMS plan filing is consistent with the Exchange Act

participants that filed the NMS plan filing.'' \141\ The description of 
the NMS plan filing, its purpose and operation, its effect, and a legal 
analysis of its consistency with applicable requirements must all be 
sufficiently detailed and specific to support an affirmative Commission 
finding.\142\ Any failure of the plan participants that filed the NMS 
plan filing to provide such detail and specificity may result in the 
Commission not having a sufficient basis to make an affirmative finding 
that the NMS plan filing is consistent with the Exchange Act and the 
applicable rules and regulations thereunder.\143\

submissions of their views, data, and arguments with respect to the 
issues identified above, as well as any other concerns they may have 
with the Proposed Amendment. In particular, the Commission invites the 
written views of interested persons concerning whether the Proposed 
Amendment is consistent with the Exchange Act, the rules and 
regulations thereunder, or any other provisions of the CAT NMS Plan. 
Although there do not appear to be any issues relevant to approval or 
disapproval that would be facilitated by an oral presentation of views, 
data, and arguments, the Commission will consider, pursuant to Rule 
608(b)(2)(i) of Regulation NMS,\144\ any request for an opportunity to 
make an oral presentation.\145\
---------------------------------------------------------------------------

    \144\ 17 CFR 242.608(b)(2)(i).
