Joint Industry Plan; Notice of Filing of Amendment to the 
National Market System Plan Governing the Consolidated Audit Trail 
Regarding CAT Funding Model

September 12, 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,

Stock Market LLC, New York Stock Exchange LLC, NYSE American LLC, NYSE 
Arca, Inc., NYSE National, Inc., and NYSE Texas, Inc. (collectively, 
the ``Participants,'' ``self-regulatory organizations,'' 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 (``Exchange Act''),\2\ and Rule 608 thereunder,\3\ 
a proposed amendment to implement a revised funding model (the 
``Funding Proposal'') for the consolidated audit trail (the ``CAT'') 
and to establish a fee schedule for Participant CAT fees in accordance 
with the Funding Proposal.\4\ Exhibit A sets forth the cumulative 
changes proposed to be made to the CAT NMS Plan. The Commission is 
publishing this notice to solicit comments from interested persons on 
the Funding Proposal.
---------------------------------------------------------------------------

    \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 
Plan Approval Order, at 84943-85034.

    \4\ See Letter from Robert Walley, CAT NMS Plan Operating 
Committee Chair, to Vanessa Countryman, Secretary, Commission, dated 
Sept. 5, 2025.
---------------------------------------------------------------------------

II. Description of the Plan

    Set forth in this Section II is the description of the proposed 
Funding Proposal, along with information required by Rule 608(a) under 
the Exchange Act,\5\ as prepared and submitted by the Participants to 
the Commission.\6\
---------------------------------------------------------------------------

    \5\ See 17 CFR 242.608(a).
    \6\ See Transmittal Letter, supra note 4. Unless otherwise 
defined herein, capitalized terms used herein are defined as set 
forth in the CAT NMS Plan.
---------------------------------------------------------------------------

    When the Commission approved the CAT NMS Plan in 2016, the 
Commission approved the funding model set forth in Article XI of the 
original CAT NMS Plan (the ``Original Funding Model''). 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.
    On September 6, 2023, the SEC approved a proposed amendment to the 
CAT NMS Plan to replace the Original Funding Model with a new funding 
model (the ``Executed Share Model'').\7\ The Executed Share Model 
charged fees based on executed equivalent share volume of transactions 
in Eligible Securities whereas the Original Funding Model charged fees 
based on market share and message traffic. In proposing the Executed 
Share Model, CAT LLC had undertaken an extensive process of evaluating 
and seeking comment on various funding models since the inception of 
CAT. In addition to the variety of alternative models considered by CAT 
LLC (as described in Section A.10 of this filing), the Executed Share 
Model was subject to substantial public review and comment via the 
proposed amendment to the CAT NMS Plan published by the SEC on May 25, 
2022 (the ``2022 Funding Proposal''),\8\ the subsequent order 
instituting proceedings related to the 2022 Funding Proposal \9\ and 
two partial amendments regarding the 2022 Funding Proposal,\10\ as well 
as the proposed amendment to the CAT NMS Plan published by the SEC on 
March 15, 2023 ultimately approved by the Commission.\11\

FR 17086 (Mar. 21, 2023) (``Executed Share Model Proposal 
Release'').
---------------------------------------------------------------------------

    Under the Executed Share Model, CAT LLC established two categories 
of CAT fees. The first category of CAT fees were 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''). The 
CAT Fee for each transaction was calculated by multiplying the executed 
equivalent shares in the transaction by one-third and the applicable 
``Fee Rate.'' The Executed Share Model described in detail each aspect 
relevant to the CAT Fees, including a description of the Prospective 
CAT Costs, the calculation of the Fee Rate, the definition of ``CAT 
Executing Broker,'' the fee filings made pursuant to Section 19(b) of 
the Exchange Act for CAT Fees, and information available related to CAT 
Fees, both publicly and upon request.
    The second category of CAT fees were 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''). The 
Historical CAT Assessment for each transaction was calculated by 
multiplying the number of executed equivalent shares in the transaction 
by one-third and the applicable ``Historical Fee Rate.'' Like with the 
CAT Fees related to Prospective CAT Costs, the Funding Proposal 
described in detail each aspect relevant to Historical CAT Assessments, 
including a description of Historical CAT Costs, the calculation of the 
Historical Fee Rate, the definition of ``CAT Executing Broker,'' the 
fee filings made pursuant to Section 19(b) of the Exchange Act for 
Historical CAT Assessments, and information available related to 
Historical CAT Assessments, both publicly and upon request.
    After the SEC approved the Executed Share Model, each Participant 
separately filed rule filings under Section 19(b) of the Exchange Act 
and

[[Page 44911]]

Rule 19b-4(f)(2) thereunder to establish CAT Fees and a Historical CAT 
Assessment to be charged to Industry Members based on the Executed 
Share Model. Specifically, to date, each of the Participants filed fee 
filings related to three CAT Fees \12\ and one Historical CAT 
Assessment,\13\ and CAT LLC has collected or is collecting such CAT 
fees. To date, the process for billing and collecting CAT fees has 
proven to be highly efficient and manageable to administer, with 
approximately 99% of CAT fees paid on time. In addition, the Plan 
Processor makes available trade-by-trade data to CAT Executing Brokers 
for each CAT bill. CAT LLC understands that many Industry Members have 
implemented processes to pass-through their CAT fees to upstream 
broker-dealers and customers.
---------------------------------------------------------------------------

    \12\ Each of the Participants filed rule filings to implement 
CAT Fee 2024-1, CAT Fee 2025-1 and CAT Fee 2025-2. See, e.g., 
Securities Exchange Act Rel. No. 100828 (Aug. 27, 2024), 89 FR 71699 
(Sept. 3, 2024) (New York Stock Exchange LLC filing for CAT Fee 
2024-1); Securities Exchange Act Rel. No. 102054 (Dec. 30, 2024), 90 
FR 714 (Jan. 6, 2025) (Long-Term Stock Exchange, Inc. filing for CAT 
Fee 2025-1); Securities Exchange Act Rel. No. 103400 (July 8, 2025), 
90 FR 30172 (July 11, 2025) (Investors Exchange LLC filing for CAT 
Fee 2025-2).
    \13\ Each of the Participants filed rule filings to implement 
Historical CAT Assessment 1. See, e.g., Securities Exchange Act Rel. 
No. 100936 (Sept. 5, 2024), 89 FR 74430 (Sept. 22, 2024) (BOX 
Exchange LLC filing for Historical CAT Assessment 1).
---------------------------------------------------------------------------

    In response to comments on the Executed Share Model that 
Participants should be prohibited from passing-on their CAT cost 
allocation to their members, CAT LLC stated that Participants are 
permitted by the Exchange Act to charge their members fees to fund the 
Participants' share of CAT fees, as long as they submit fee filings 
that demonstrate that any proposed fee is consistent with the Exchange 
Act.\14\ The Commission's 2012 order adopting Rule 613 specifically 
acknowledges that the Participants may seek to pass-through CAT 
costs,\15\ the CAT NMS Plan approved in 2016 contemplates that 
``Participants may charge their members to cover the CAT NMS Plan costs 
either explicitly or subsume those costs in other fees or 
assessments,'' \16\ and the Commission's 2023 order approving the 
Executed Share Model explains that Participants could choose to pass-
through their CAT fee allocations to their members subject to the 
Section 19(b) fee filing process.\17\ To date, however, only FINRA has 
sought to pass-through its CAT fees. The CAT NMS Plan itself does not 
address whether Industry Members may pass-through their CAT fees to 
their investors.
---------------------------------------------------------------------------

    \14\ See Executed Share Model Approval Order at 62635.
    \15\ See Securities Exchange Act Rel. No. 67457 (Jul. 18, 2012), 
77 FR 45722, 45795 (Aug. 1, 2012) (``Rule 613 Adopting Release'') 
(``[A]lthough the plan sponsors likely would initially incur the 
costs to establish and fund the central repository directly, they 
may seek to recover some or all of these costs from their 
members.'').

2016) (``CAT NMS Plan Approval Order'') (``[T]he Participants are 
permitted to recoup their regulatory costs under the Exchange Act 
through the collection of fees from their members, as long as such 
fees are reasonable, equitably allocated and not unfairly 
discriminatory, and otherwise are consistent with Exchange Act 
standards.'').
    \17\ Executed Share Model Approval Order at 62655.
---------------------------------------------------------------------------

    On July 25, 2025, the U.S. Court of Appeals for the Eleventh 
Circuit vacated the Commission's order approving the Executed Share 
Model,\18\ finding that the Executed Share Model Approval Order 
violated the Administrative Procedures Act as a result of (1) the 
Commission allowing for the possibility for ``self-regulatory 
organizations to pass through 100% of their fees to broker-dealers--
without considering the effects of that choice,'' \19\ and (2) the 
Commission failing to ``conduct a new economic analysis or revise its 
previous economic analysis'' \20\ in the Executed Share Model Approval 
Order. The Court acknowledged that no self-regulatory organization 
other than FINRA has asked for 100% pass-through approval so far, but 
noted that the Executed Share Model Approval Order does not limit the 
potential for 100% pass-through costs to FINRA. The Court temporarily 
stayed its order to allow the SEC to conduct a new economic analysis 
and to reconsider the allocation of Historical CAT Costs and 
Prospective CAT Costs in accordance with the Court's opinion. Once the 
Court's judgment takes effect, however, there will be no ongoing source 
of funding for the continued operation of the CAT absent further 
Commission action.\21\
---------------------------------------------------------------------------

    \18\ Am. Sec. Ass'n, Citadel Sec. LLC v. U.S. Sec. & Exch. 
Comm'n, No. 23-13396, 2025 WL 2092054 (11th Cir. July 25, 2025).
    \19\ Id. at 20.
    \20\ Id. at 24.
    \21\ Prior to the SEC's approval of the Executed Share Model, 
CAT was funded entirely by voluntary loans from the Participants; 
such an approach is not sustainable.
---------------------------------------------------------------------------

    To address the pass-through fee discussion in the Eleventh 
Circuit's opinion, CAT LLC proposes to add a new paragraph (e) to 
Section 11.3 providing that each Participant agrees not to establish a 
new fee for passing through its CAT fees.\22\ The proposed amendment 
does not address whether Industry Members may pass-through their CAT 
fees to their customers; as discussed below, CAT LLC understands that 
many Industry Members do pass-through their CAT fees. Subject to the 
addition of this new paragraph and a discussion thereof, the Funding 
Proposal set forth herein is the same proposal as the Executed Share 
Model. The changes made to the Executed Share Model are noted in this 
filing, and separately identified in Exhibit B to this filing.
---------------------------------------------------------------------------

    \22\ Appendix C of the CAT NMS Plan provides that ``Participants 
may charge their members to cover the CAT NMS Plan costs either 
explicitly or subsume those costs in other fees or assessments.'' 
Because the Commission has acknowledged that Appendix C was not 
intended to be continually updated once the CAT NMS Plan was 
approved, CAT LLC is not proposing to update Appendix C to reflect 
the proposed amendments. See Securities Exchange Act Rel. No. 89632 
(Aug. 21, 2020), 85 FR 65990 (Oct. 16, 2020).
---------------------------------------------------------------------------

    The Participants and the Commission depend on the CAT for vital 
regulatory functions, but the CAT cannot exist without a viable funding 
model. CAT LLC welcomes the SEC Chairman's leadership in calling for a 
comprehensive review of the CAT and will be working collaboratively and 
expeditiously with the Commission to dramatically reduce CAT costs 
while preserving effective market oversight and surveillance, but it is 
also critical to resolve the fundamental issue of how to fund the CAT. 
The Commission has long recognized that, ``[b]ecause the CAT is a 
critical regulatory tool/system, the CAT needs to have a stable funding 
source to build financial stability to support the Company as a going 
concern,'' and that ``[f]unding for the CAT, as noted in Section 
11.1(b), is the responsibility of the Participants and the industry.'' 
\23\ While reducing overall CAT operating costs remains a top priority, 
the Commission should simultaneously ensure the necessary funding still 
exists to operate the CAT.
---------------------------------------------------------------------------

    \23\ Executed Share Model Approval Order at 62657.
---------------------------------------------------------------------------

    The Funding Proposal would provide reasonable fees that are 
equitably allocated, not unfairly discriminatory, and do not impose an 
undue burden on competition, in that the proposal 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. Moreover, the Funding Proposal would be consistent with past 
fee structures that have been approved by the Commission. It also is 
transparent, has proven to be relatively easy to calculate and 
administer, and is designed not to have an impact on market activity 
because it is neutral as to the location and manner of execution.

[[Page 44912]]

The Exchange Act does not require CAT LLC to demonstrate that the 
Funding Proposal is superior to any other potential proposal. Instead, 
CAT LLC must demonstrate that the Funding Proposal is consistent with 
the Exchange Act and the rules and regulations thereunder. CAT LLC 
believes that the Funding Proposal satisfies the requirements of the 
Exchange Act and the Eleventh Circuit's opinion and should be approved 
by the Commission.

Requirements Pursuant to Rule 608(a)

A. Description of the Proposed Amendments to the CAT NMS Plan
    CAT LLC describes in detail the Funding Proposal in this Section A. 
As noted above, other than the addition of new paragraph (e) to Section 
11.3 providing that each Participant agrees not to establish a new fee 
for passing through its CAT fees, the proposed amendments set forth in 
Exhibit A of this filing are identical to the amendments adopted in the 
Executed Share Model Approval Order. The Executed Share Model was 
approved in 2023 and the first CAT Fees and Historical CAT Assessments 
based on the Executed Share Model were introduced in 2024. In this 
time, the Commission, Participants and Industry Members all have gained 
substantial experience through the implementation of the funding model 
and in how the model operates, including, for example, how CAT fees are 
calculated and charged to a CAT Executing Broker. In addition, the 
process for issuing and paying CAT invoices has proven to work 
effectively.\24\ Accordingly, other than addressing the pass-through 
fee discussion in the Eleventh Circuit's opinion, the Funding Proposal 
does not introduce any novel regulatory or operational issues.
---------------------------------------------------------------------------

    \24\ There have been only three fee dispute applications filed 
(two of which were by the same firm relating to the same issue) out 
of approximately 5,778 invoices issued through August 2025. Those 
few issues were promptly resolved via a corrected invoice without 
the need for a decision made through the formal fee dispute 
resolution process.

alternative funding models to the Funding Proposal in Section A.10 
of this filing.
    <bullet> Satisfaction of Exchange Act and CAT NMS Plan 
Requirements: CAT LLC discusses how the Funding Proposal satisfies 
each of the funding principles and other requirements of the CAT NMS 
Plan, as proposed to be revised herein, as well as the applicable 
requirements of the Exchange Act in Section A.11 of this filing.
1. Definition of CAT Executing Broker
    Under the Funding Proposal, each Industry Member that is a CAT 
Executing Broker 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'') would be required to pay CAT Fees and Historical CAT 
Assessments. Accordingly, CAT LLC proposes to add a definition of the 
term ``CAT Executing Broker'' to Section 1.1 of the CAT NMS Plan. CAT 
LLC would define ``CAT Executing Broker'' to mean:

    (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.

    Under the Participant Technical Specifications, for transactions 
occurring on a Participant exchange, there is a field for the exchange 
to report the market participant identifier (``MPID'') of ``the member 
firm that is responsible for the order on this side of the trade.'' 
\25\ The Industry Members identified in these fields for the 
transaction reports would be the CAT Executing Brokers for transactions 
executed on an exchange. Specifically, the following fields of the 
Participant Technical Specifications would indicate the CAT Executing 
Brokers for the transactions executed on an exchange.

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

    FINRA is required to report to the CAT transactions in Eligible 
Securities reported to a FINRA trade reporting facility (i.e., the 
FINRA Trade Reporting Facilities (``TRF''), Over-the Counter Reporting 
Facility (``ORF'') and Alternative Display Facility (``ADF'')).\28\ 
Under the Participant Technical Specifications, for such transactions 
reported to a FINRA trade reporting facility, FINRA is required to 
report the MPID of the executing party as well as the MPID of the 
contra-side executing party. The Industry Members identified in these 
two fields for the transaction reports would be the CAT Executing 
Brokers for over-the-counter transactions. Specifically, the following 
fields of the Participant Technical Specifications will indicate the 
CAT Executing Brokers for the transactions executed otherwise than on 
an exchange.
---------------------------------------------------------------------------

    \26\ See Table 23, Section 4.7 (Order Trade Event) of the

                                                                              party.
----------------------------------------------------------------------------------------------------------------

    Note that a CAT Executing Broker in over-the-counter transactions 
identified on the TRF/ORF/ADF Transaction Data Event is determined 
based on the tape or media report, that is, a trade report that is 
submitted to a FINRA trade reporting facility and reported to and 
publicly disseminated by the appropriate exclusive Securities 
Information Processor. A CAT Executing Broker for over-the-counter 
transactions is not determined based on a non-tape report (e.g., a 
regulatory report or a clearing report), which are not publicly 
disseminated.\30\
---------------------------------------------------------------------------

    \30\ There is an exception to this statement for away-from-
market trades. These are non-media trades reported to the TRF with 
an ``SRO Required Modifier Code'' of ``R''.
---------------------------------------------------------------------------

    Therefore, with respect to transactions on an exchange and over-
the-counter transactions, CAT LLC would use transaction reports 
reported to the CAT by FINRA or the exchanges to identify the 
transaction for purposes of calculating the CAT fees as well as the CAT 
Executing Broker for each transaction for purposes of calculating the 
CAT fees. Accordingly, all data used to calculate the fees under the 
Funding Proposal would be CAT Data, and, therefore, it would be 
available through the CAT for calculating CAT fees. The Plan Processor 
would be responsible for calculating the CAT fees and submitting 
invoices to the CAT Executing Brokers based on this CAT Data. Moreover, 
defining a ``CAT Executing Broker'' in this way is a simpler analytical 
approach than other potential approaches for defining the relevant 
executing broker, such as identifying the originating broker for the 
order via an evaluation of CAT linkages.\31\
---------------------------------------------------------------------------

    \31\ Each CAT Executing Broker could determine, but would not be 
required, to pass their CAT fees through to their clients, who, in 
turn, could pass their CAT fees to their clients, until the fee is 
imposed on the ultimate participant in the transaction.
---------------------------------------------------------------------------

    CAT LLC proposes to make use of the defined term ``CAT Executing 
Broker'' in Proposed Section 11.3 in describing the Funding Proposal. 
CAT LLC believes the proposed definition of CAT Executing Broker and 
the use of the defined term in Article XI would set forth clearly when 
and in what situations an Industry Member would be considered a CAT 
Executing Broker for purposes of the Funding Proposal.
a. Treatment of ATSs
    The Funding Proposal would describe how CAT fees would be assessed 
with regard to transactions executed on ATSs, including clarification 
as to which party to an ATS transaction would be treated as the CAT 
Executing Broker for purposes of the Funding Proposal. The definition 
of a ``CAT Executing Broker'' as proposed above would determine the CAT 
Executing Brokers for transactions executed on an ATS. Specifically, if 
an ATS is identified as the executing party and/or the contra-side 
executing party in the TRF/ORF/ADF Transaction Data Event, then the ATS 
would be a CAT Executing Broker for purposes of the Funding Proposal. 
If the ATS is identified as the executing party for the buyer in such 
transaction reports, then the ATS would be the CAT Executing Broker for 
the

[[Page 44914]]

Buyer, and if the ATS is identified as the executing party for the 
seller in such transaction reports, then the ATS would be the CAT 
Executing Broker for the Seller. An ATS also could be identified as 
both the CAT Executing Broker for the Buyer and the CAT Executing 
Broker for the Seller. ATSs would determine the executing party and the 
contra-side executing party reported to FINRA's equity trading 
facilities in accordance with the transaction reporting requirements 
for FINRA's equity trading facilities.
b. Treatment of Fractional Shares
    The Funding Proposal also would address how transactions in 
fractional shares would be treated. As described above, CAT fees would 
be charged based on the Equity Order Trade Events, Options Trade Events 
and the ADF/ORF/TRF Transaction Data Events in the Participant 
Technical Specifications. None of these transaction reports provide for 
fractional quantities; the transaction reports must reflect whole 
shares/contracts. Therefore, under the Funding Proposal, CAT fees would 
be calculated without reference to fractional shares or fractional 
share components of executed orders.\32\
---------------------------------------------------------------------------

    \32\ To the extent that FINRA's equity transaction reporting 
facilities or the exchanges report transactions in fractional shares 
in the future, then the calculation of CAT fees would reflect 
fractional shares as well.
---------------------------------------------------------------------------

c. Non-Industry Members on Transaction Reports
    The Funding Proposal also would address how transactions that 
involve a non-Industry Member would be treated under the Funding 
Proposal (e.g., for internalized trades or trades with a non-FINRA 
member). The FINRA trade reporting requirements state that ``[w]hen 
reporting a trade with a broker-dealer that is not a FINRA member, the 
non-member should not be identified on the trade report as the contra 
party to the trade.'' \33\ Accordingly, when the transaction in these 
cases is reported to CAT via the TRF/ORF/ADF Transaction Data Event, 
the field for the reportingExecutingMpid would be populated with the 
MPID of the executing broker and the field for the contraExecutingMpid 
would be blank or null. As noted above, the reportingExecutingMpid is a 
required field (include key = `R') that must be entered on all CAT 
reports, but the contraExecutingMpid field is conditional; it does not 
need to be populated, specifically to account for cases like those at 
issue here (e.g., transactions with a non-FINRA member). Therefore, in 
those scenarios where the contraExecutingMpid is blank, the FINRA 
member identified in the reportingExecutingMpid field would be treated 
as the CAT Executing Broker for both the buy-side and the sell-side of 
the transaction, that is, as the CEBS and CEBB.
---------------------------------------------------------------------------

    \33\ FINRA Trade Reporting FAQ 202.1.
---------------------------------------------------------------------------

    In addition, under the FINRA trade reporting requirements, there is 
a limited exception to the general rule about not reporting a non-
member as the contra party to the trade. Specifically, pursuant to 
FINRA Trade Reporting FAQ 202.1, ``[t]here is a limited exception where 
a Canadian non-member firm uses the FINRA/NASDAQ TRF or ORF for 
purposes of comparing trades pursuant to a valid Non-Member Addendum to 
the NASDAQ Services Agreement. In that instance, however, the Canadian 
non-member must appear on the trade report as the contra party to the 
trade and not as the reporting party. For any trade report on which a 
Canadian non-member appears as a party to the trade, the FINRA member 
must appear as the reporting party.'' In this case involving the 
Canadian non-member firm exception, the executing broker identified in 
the reportingExecutingMpid field would be billed for both sides of the 
transaction.
    CAT LLC proposes to include language in the definition of ``CAT 
Executing Broker'' to address these scenarios. Specifically, CAT LLC 
proposes to state the following in the definition of ``CAT Executing 
Broker: ``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.''
d. Cancellations and Corrections
    The Funding Proposal also would provide for cancellations and 
corrections. CAT LLC expects to determine CAT fees based on the 
transaction reports for a month as of a particular day. To the extent 
that changes are made to the transaction reports on or before the day 
the CAT fees are determined for the given month, the changes will be 
reflected in the monthly bill. To the extent that changes are made to 
the transaction reports after the day the CAT fees are determined for 
that month, subsequent bills will reflect any changes via debits or 
credits, as applicable. As CAT LLC is required under the CAT NMS Plan 
to adopt policies, procedures, and practices regarding the billing and 
collection of fees,\34\ CAT LLC will establish specific policies and 
procedures regarding the treatment of such adjustments as those related 
to cancellations and corrections. Furthermore, CAT LLC will inform 
Industry Members and other market participants of these policies and 
procedures via FAQs, CAT Alerts and/or other appropriate methods.
---------------------------------------------------------------------------

    \34\ Section 11.1(d) of the CAT NMS Plan.
---------------------------------------------------------------------------

2. 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.'' CAT LLC proposes to provide additional detail regarding the 
CAT LLC operating budget by adding proposed subparagraphs (i) and (ii) 
to Section 11.1(a) of the CAT NMS Plan. Such detailed information would 
provide Participants, Industry Members and other interested parties 
with a clear understanding of the CAT budget, and, in turn, the 
calculation of the CAT Fees.
a. Budgeted CAT Costs
    CAT LLC proposes to add subparagraph (i) to Section 11.1(a) of the 
CAT NMS Plan to provide additional clarity regarding the costs to be 
included in the CAT budget. This proposed provision would 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.''
    Because technology costs account for more than 90% of CAT 
costs,\35\ CAT

[[Page 44915]]

LLC proposes to provide more granular information about such costs. 
Specifically, CAT LLC 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. 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.\36\ CAT LLC 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. However, CAT LLC will consider the need to provide 
additional cost disclosure going forward.
---------------------------------------------------------------------------

    \35\ This percentage is based on the 2025 Financial and 
Operating Budget. See CAT, LLC, 2025 Financial and Operating Budget 
(May 19, 2025), <a href="https://www.catnmsplan.com/sites/default/files/2025-05/05.19.25-CAT-LLC-2025-Financial_and_Operating-Budget.pdf">https://www.catnmsplan.com/sites/default/files/2025-05/05.19.25-CAT-LLC-2025-Financial_and_Operating-Budget.pdf</a>.
    \36\ 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>.
---------------------------------------------------------------------------

    Furthermore, CAT LLC has determined not to provide more detailed 
subcategories for the other cost categories (that is, legal, 
consulting, insurance, professional and administration, and public 
relations costs) at this time. Breaking out these costs into further 
subcategories would establish new subcategories that are not set forth 
in the budgets. In addition, these costs in the aggregate represent 
less than six percent (6%) of total CAT costs, with professional and 
administration costs and public relations costs, in particular, each 
representing less than one percent (1%) of overall CAT costs.\37\ 
Therefore, CAT LLC does not believe that these costs warrant additional 
subcategory disclosure. CAT LLC further notes that it is not considered 
a best practice to publicly disclose detailed legal or insurance 
information, which is particularly sensitive. Nevertheless, 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.
---------------------------------------------------------------------------

    \37\ This percentage is based on the 2025 Financial and 
Operating Budget. See CAT, LLC, 2025 Financial and Operating Budget 
(May 19, 2025), <a href="https://www.catnmsplan.com/sites/default/files/2025-05/05.19.25-CAT-LLC-2025-Financial_and_Operating-Budget.pdf">https://www.catnmsplan.com/sites/default/files/2025-05/05.19.25-CAT-LLC-2025-Financial_and_Operating-Budget.pdf</a>. In 
addition, CAT LLC has not incurred public relations costs since Q1 
2025, and the 2025 Financial and Operating Budget does not 
contemplate any public relations costs will be incurred through the 
remainder of 2025.
---------------------------------------------------------------------------

    CAT LLC also intends to determine costs for the operating budget 
for the CAT in a reasonable manner. Accordingly, CAT LLC proposes to 
amend Section 11.1(a) of the CAT NMS Plan to refer to a ``reasonable'' 
operating budget for CAT LLC. Specifically, the first sentence of 
Section 11.1(a) of the CAT NMS Plan would be revised to read: ``On an 
annual basis the Operating Committee shall approve a reasonable 
operating budget for the Company.'' In addition, CAT LLC proposes to 
include the term ``reasonably'' in proposed paragraph (a)(i) of Section 
11.1 of the CAT NMS Plan. Specifically, CAT proposes to introduce the 
term ``reasonably'' to the following proposed provision of the CAT NMS 
Plan: ``Without 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 cost categories as reasonably determined by the 
Operating Committee to be included in the budget.''
    Finally, CAT LLC proposes to amend Section 11.1(b) of the CAT NMS 
Plan. Currently, Section 11.1(b) of the CAT NMS Plan states that:

    Subject to Section 11.2, the Operating Committee shall have 
discretion to establish funding for the Company, including: (i) 
establishing fees that the Participants shall pay; and (ii) 
establishing fees for Industry Members that shall be implemented by 
Participants. The Participants shall file with the SEC under Section 
19(b) of the Exchange Act any such fees on Industry Members that the 
Operating Committee approves, and such fees shall be labeled as 
``Consolidated Audit Trail Funding Fees.''

    CAT LLC proposes to amend Section 11.1(b) to include a reference to 
Section 11.1 as well as Section 11.2 in the ``subject to'' clause at 
the beginning of the provision. CAT LLC believes this reference is 
relevant because Section 11.1 sets forth requirements related to the 
budget, and the budget is used in calculating CAT Fees.
b. Reserve
    Section 11.1(a) of the CAT NMS Plan states that the budget shall 
include ``the funding of any reserve that the Operating Committee 
reasonably deems appropriate for prudent operation of the Company.'' In 
addition, Proposed Section 11.1(a)(i) of the CAT NMS Plan would state 
that the budgeted CAT costs shall include a reserve. Section 11.1(c) of 
the CAT NMS Plan states that ``[a]ny surplus of the Company's revenues 
over its expenses shall be treated as an operational reserve to offset 
future fees.'' CAT LLC proposes to add subparagraph (ii) to Section 
11.1(a) of the CAT NMS Plan to provide additional details regarding the 
size and use of the reserve.
    To provide additional clarity regarding the size of the reserve, 
CAT LLC proposes to add proposed paragraph (ii) to Section 11.1(a) of 
the CAT NMS Plan to set forth the parameters for the size of the 
reserve. Based on the difficulty in accurately predicting various 
variable CAT costs, CAT LLC believes that a 25% reserve would appear to 
be reasonable. Accordingly, Proposed Section 11.1(a)(ii) of the CAT NMS 
Plan would state that ``[f]or the reserve referenced in paragraph 
(a)(i) of this Section, 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.'' CAT LLC also intends to include a reserve 
in the CAT budget that is ``reasonably'' necessary to allow the CAT LLC 
to maintain a reserve of not more than 25% of the annual budget. 
Accordingly, CAT LLC proposes to include the term ``reasonably'' in 
this sentence. Moreover, CAT LLC would calculate the reserve based on 
the amount of the budget other than the reserve, as the reserve is 
intended to provide funds for CAT LLC to pay its bills if necessary. 
Accordingly, 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 also believes that it is reasonable to base the reserve on 
a percentage of the budget. First, CAT LLC believes that setting the 
reserve at 25% of the budget is appropriate in light of the timeline 
for the collection of CAT fees.\38\ Many of CAT LLC's bills must be 
paid on a monthly basis. However, CAT fees will be collected 
approximately three months after the activity on which a CAT fee is 
based--that is, 25% of the year. For example, activity in January would 
be subject to a bill in February, which would be required to be paid 
within 30 days,\39\ which would be in March. Accordingly, the reserve 
would be available to address the funding

[[Page 44916]]

needs related to the delay in CAT LLC's receipt of the CAT fees.
---------------------------------------------------------------------------

    \38\ For a discussion of the billing and collection of CAT fees, 
see Section A.8 of this filing.
    \39\ See Sections 3.7(b) and 11.4 of the CAT NMS Plan.
---------------------------------------------------------------------------

    Second, CAT LLC has established a number of measures for 
establishing a reasonable budget for the CAT, thereby providing a 
reasonable starting point for the reserve calculation. For example, the 
CAT NMS Plan would require the budget to be ``reasonable.'' \40\ The 
Fee Rate established at the beginning of the year would be adjusted 
mid-year to address changes in the actual or budgeted costs or changes 
in the actual or projected executed equivalent share volume. CAT LLC 
has established a variety of cost management measures, as discussed in 
detail in Section A.9.bb of this filing, and has and would provide 
substantial cost transparency as discussed in detail in Section A.9.l 
of this filing. The CAT fee filings pursuant to Section 19(b) of the 
Exchange Act would provide a description of how the budget is 
reconciled to the collected fees.
---------------------------------------------------------------------------

    \40\ See Proposed Section 11.1(a) of the CAT NMS Plan.
---------------------------------------------------------------------------

    CAT LLC proposes to provide additional clarification regarding the 
collection of the reserve by providing additional information as to how 
budget surpluses would be treated for purposes of the reserve. CAT LLC 
proposes to clarify how CAT fees collected in excess of CAT costs, 
including the reserve, would be used. 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).''
    The following examples explain the circumstances under which a 
reserve would be included in the budget:
    (1) Suppose that the Operating Committee had approved a budget of 
$100 million for CAT costs for Year X, and a reserve of $25 million, 
for a total budget of $125 million for Year X. Suppose that CAT Fees of 
$125 million were collected during Year X, and that actual CAT costs 
for Year X were $100 million. Therefore, CAT ended Year X with $25 
million in reserve. Suppose further that the Operating Committee had 
approved a budget of $100 million for CAT costs and a reserve of $25 
million, for a total budget of $125 million for Year X+1. Because CAT 
LLC had collected $25 million in excess of costs for the reserve in 
Year X, and the excess was not necessary to cover additional costs in 
Year X, CAT LLC would not include any additional amount in the budget 
for a reserve for Year X+1. CAT LLC would use the excess fees collected 
for the reserve.
    (2) Suppose that the Operating Committee had approved a budget of 
$100 million for CAT costs for Year Y, and a reserve of $25 million, 
for a total budget of $125 million for Year Y. Suppose that CAT Fees of 
$110 million were collected during Year Y, and that actual CAT costs 
for Year Y were $100 million. Therefore, CAT ended Year Y with $10 
million in reserve. Suppose further that the Operating Committee had 
approved a budget of $100 million for CAT costs, and a reserve of $25 
million, for a total budget of $125 million for Year Y+1. Because CAT 
LLC had collected $10 million in excess of costs for the reserve in 
Year Y, and the entire reserve was not necessary to cover additional 
costs in Year Y, CAT LLC would only need to collect an additional $15 
million for the reserve in Year Y+1, not $25 million.
c. Publicly Available Budgets
    CAT LLC publicly provides the annual operating budget for the 
Company as well as updates to the budget that occur during the 
year.\41\ This publicly available budget information describes in 
detail the budget for the Company. For example, among other things, the 
budget provides specific budgeted technology costs (including cloud 
hosting services, operating fees, CAIS operating fees and change 
request fees) and general and administrative costs (including legal, 
consulting, insurance, professional and administration, and public 
relations). The Company provides such budget information on a dedicated

CAT Reporters and others.

    \41\ To address potential changes related to the CAT during the 
year, the Operating Committee may adjust the budgeted CAT costs for 
the year as it reasonably deems appropriate for the prudent 
operation of the Company. For example, the Operating Committee may 
determine that an adjustment to the budget is necessary if actual 
costs during the year are more or less than the budget, or if 
unanticipated expenditures are necessary. To the extent that the 
Operating Committee adjusts the budgeted CAT costs during the year 
and determines to adjust the Fee Rate, the adjusted budgeted CAT 
costs would be used in calculating the new Fee Rate for the 
remaining months of the year.

3. CAT Fees Related to Prospective CAT Costs
    CAT LLC proposes to describe CAT Fees related to Prospective CAT 
Costs in Section 11.3(a) of the CAT NMS Plan. Proposed Section 11.3(a) 
of the CAT NMS Plan would describe that the CAT Fees related to 
Prospective CAT Costs apply to both Participants and Industry Members, 
the manner of calculating the Fee Rate for CAT Fees, the description of 
the calculation of the Participant CAT Fees, a description of the 
calculation of the Industry Member CAT Fees, a description of the fee 
filings under Section 19(b) of the Exchange Act for Industry Member CAT 
Fees, and details regarding the calculation of the CAT Fees that are 
available upon request or publicly available. The following describes 
Proposed Section 11.3(a) of the CAT NMS Plan in detail.
a. Introductory Statement
    CAT LLC proposes to revise Section 11.3(a) of the CAT NMS Plan to 
address CAT Fees related to Prospective CAT Costs for both Participants 
and Industry Members. Accordingly, CAT LLC proposes to revise the 
introductory statement in Proposed Section 11.3(a) of the CAT NMS Plan 
to state that ``[t]he Operating Committee will establish fees (`CAT 
Fees') to be payable by Participants and Industry Members with regard 
to CAT costs not previously paid by the Participants (`Prospective CAT 
Costs') as follows:''.
b. Fee Rate for CAT Fees
    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. 
Specifically, this proposed provision would state that ``[t]he 
Operating Committee will calculate the Fee Rate for the CAT Fee twice 
per year, once at the beginning of the year and once during the year as 
follows.'' CAT LLC recognizes the need to align CAT Fees with CAT 
costs. Requiring the adjustment of the Fee Rate both at the beginning 
of the year and once mid-year in response to changes in the budgeted or 
actual costs or projected or actual total executed equivalent share 
volume during the year would likely lead to the greater alignment of 
CAT Fees and CAT costs, thereby potentially avoiding the collection of 
CAT Fees in excess of CAT costs or CAT Fees that

[[Page 44917]]

are insufficient to cover CAT costs. Accordingly, CAT LLC proposes to 
require both an annual and a mid-year adjustment of the Fee Rate for 
the CAT Fee.
i. General
    CAT LLC proposes to provide details regarding the calculation of 
the Fee Rate for the CAT Fees in Proposed Section 11.3(a)(i) of the CAT 
NMS Plan. The detail provided in Proposed Section 11.3(a)(i) of the CAT 
NMS Plan would include a description of the calculation of the Fee Rate 
at the beginning of the year and during the year, the counting method 
for executed equivalent shares, the budgeted CAT costs, and the 
projected total executed equivalent share volume of transactions in 
Eligible Securities for the relevant period. Each of these aspects of 
the CAT Fees are discussed in more detail below.
A. Annual Calculation of Fee Rate
    Proposed Section 11.3(a)(i)(A)(I) of the CAT NMS Plan would 
describe the annual calculation of the Fee Rate and the requirement for 
Participants to file a fee filing for CAT Fees to be charged Industry 
Members calculated using the Fee Rate. This proposed provision also 
would state that Participants and Industry Members would be required to 
pay such CAT Fees once the CAT Fees are in effect with regard to 
Industry Members. Specifically, this proposed provision would state:

    For 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 SEC 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.

    CAT LLC proposes to clarify that the annual calculation of CAT Fees 
would be performed using reasonably budgeted CAT costs and reasonably 
projected total executed equivalent share volume. Accordingly, CAT LLC 
proposes to use the term ``reasonably'' twice in the following 
sentence: ``For 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.''
B. Mid-Year Calculation of Fee Rate
    Proposed Section 11.3(a)(i)(A)(II) of the CAT NMS Plan describes 
the mandatory mid-year calculation of a new Fee Rate. This proposed 
provision would describe the mid-year calculation of the Fee Rate and 
the requirement for Participants to file a fee filing for CAT Fees to 
be charged Industry Members calculated using the Fee Rate. This 
proposed provision also would state that Participants and Industry 
Members would be required to pay such CAT Fees once the CAT Fees are in 
effect with regard to Industry Members. Specifically, this proposed 
provision would state:

    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 SEC 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 proposes to clarify that CAT Fees would be calculated 
during the year using reasonably budgeted CAT costs and reasonably 
projected total executed equivalent share volume. Accordingly, CAT LLC 
proposes to use the term ``reasonably'' twice in the following 
sentence: ``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.''
C. Continuing CAT Fee
    CAT LLC also proposes to add Section 11.3(a)(i)(A)(III) to the CAT 
NMS Plan to clarify 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 Funding Proposal is 
designed to collect CAT fees continuously so as to provide 
uninterrupted revenue to pay CAT bills. Specifically, this proposed 
provision would state:

    For the avoidance of doubt, CAT Fees with a Fee Rate calculated 
as set forth in this paragraph (a)(i) shall remain in effect until 
the Operating Committee approves a new Fee Rate as described in this 
paragraph (a)(i) and CAT Fees with the new Fee Rate are in effect 
with regard to Industry Members in accordance with Section 19(b) of 
the Exchange Act.
D. Commencement of CAT Fee
    CAT LLC believes that it would be appropriate to commence the first 
CAT Fee either at the beginning of the year or during the year (due to, 
for example, mid-year approval of the CAT Fee by the SEC), whichever is 
closest to the time that such a CAT Fee could become effective, so as 
to seek prompt recovery of CAT costs. If the CAT Fee were to commence 
during the year, the first CAT Fee would be calculated in the same way 
that a mid-year CAT Fee would be calculated. To clarify this approach, 
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.''
ii. Executed Equivalent Shares
    CAT LLC proposes to describe in Proposed Section 11.3(a)(i)(B) of 
the CAT NMS Plan how executed equivalent shares would be counted for 
purposes of calculating CAT Fees. Under the Funding Proposal, a CAT Fee 
would be charged with regard to each transaction in Eligible Securities 
as reported in CAT Data. As set forth in Section 1.1 of the CAT NMS 
Plan, ``Eligible Securities'' are defined to include all NMS Securities 
and all OTC Equity Securities. Section 1.1 of the CAT NMS Plan, in 
turn, defines an ``NMS Security'' as ``any security or class of 
securities for which transaction reports are collected, processed, and 
made available pursuant to an effective transaction reporting plan, or 
an effective national market system plan for reporting transactions in 
Listed Options.'' In addition, Section 1.1 of the CAT NMS Plan defines 
an ``OTC Equity Security'' as ``any equity security, other than an NMS 
Security, subject to prompt last sale reporting rules of a registered 
national securities association and reported to one of such 
association's equity trade reporting facilities.'' A CAT Fee would be 
imposed with regard to transactions in Eligible Securities in the CAT 
Data regardless of whether the trade is executed on an exchange or 
otherwise than on an exchange.

[[Page 44918]]

    The Funding Proposal uses the concept of executed equivalent shares 
as the transactions subject to a CAT Fee involve NMS Stocks, Listed 
Options and OTC Equity Securities, each of which have different trading 
characteristics.
    NMS Stocks. Under the Funding Proposal, each executed share for a 
transaction in NMS Stocks would be counted as one executed equivalent 
share. Accordingly, Proposed Section 11.3(a)(i)(B)(I) of the CAT NMS 
Plan would state that ``[f]or purposes of calculating CAT Fees, 
executed equivalent shares in a transaction in Eligible Securities will 
be reasonably counted as follows: (I) each executed share for a 
transaction in NMS Stocks will be counted as one executed equivalent 
share.''
    Listed Options. Recognizing that Listed Options trade in contracts 
rather than shares, each executed contract for a transaction in Listed 
Options will be counted using the contract multiplier applicable to the 
specific Listed Option in the relevant transaction. Typically, a Listed 
Option contract represents 100 shares; however, it may also represent 
another designated number of shares. Accordingly, Proposed Section 
11.3(a)(i)(B)(II) of the CAT NMS Plan would state that ``[f]or purposes 
of calculating CAT Fees, executed equivalent shares in a transaction in 
Eligible Securities will be reasonably counted as follows: . . . (II) 
each executed contract for a transaction in Listed Options will be 
counted based on the multiplier applicable to the specific Listed 
Option (i.e., 100 executed equivalent shares or such other applicable 
multiplier).''
    OTC Equity Securities. Similarly, in recognition of the different 
trading characteristics of OTC Equity Securities as compared to NMS 
Stocks, the Funding Proposal would discount the share volume of OTC 
Equity Securities when calculating CAT Fees. Many OTC Equity Securities 
are priced at less than one dollar--and a significant number are priced 
at less than one penny--per share and low-priced shares tend to trade 
in larger quantities. Accordingly, a disproportionately large number of 
shares are involved in transactions involving OTC Equity Securities 
versus NMS Stocks.\42\ Because the Funding Proposal would calculate CAT 
Fees based on executed share volume, CAT Reporters trading OTC Equity 
Securities would likely be subject to higher fees than their market 
activity may warrant. To address this potential concern, the Funding 
Proposal would count each executed share for a transaction in OTC 
Equity Securities as 0.01 executed equivalent shares. Accordingly, 
Proposed Section 11.3(a)(i)(B)(III) of the CAT NMS Plan would state 
that ``[f]or purposes of calculating CAT Fees, executed equivalent 
shares in a transaction in Eligible Securities will be reasonably 
counted as follows: . . . (III) each executed share for a transaction 
in OTC Equity Securities shall be counted as 0.01 executed equivalent 
share.''
---------------------------------------------------------------------------

    \42\ For example, based on data from 2021, (1) the average price 
per executed share of OTC Equity Securities was $0.072 and the 
average price per executed share for NMS Stocks was $49.51; and (2) 
the average trade size for OTC Equity Securities was 63,474 and the 
average trade size for NMS Stocks was 166 shares. Trades in OTC 
Equity Securities accounted for 77% of the number of all equity 
shares traded, but only 0.51% of the notional value of all equity 
shares traded.
---------------------------------------------------------------------------

    The discount to 1% was selected based on a reasoned analysis of a 
variety of different metrics for comparing the markets for OTC Equity 
Securities and NMS Stocks, rather than a simple calculation. For 
example, using 2021 data, the Operating Committee calculated the 
following metrics: (1) the ratio of total notional dollar value traded 
for OTC Equity Securities to OTC Equity Securities and NMS Stocks was 
0.051%; (2) the ratio of total trades in OTC Equity Securities to total 
trades in OTC Equity Securities and NMS Stocks was 0.90%; and (3) the 
ratio of average share price per trade of OTC Equity Securities to 
average share price per trade for OTC Equity Securities and NMS Stocks 
was 0.065%. In recognition of the fact that these calculations involve 
averages and for ease of application, the Operating Committee 
determined to round these metrics to 1%.
    In calculating CAT Fees, CAT LLC intends for executed equivalent 
shares in a transaction in Eligible Securities to be reasonably 
counted. Accordingly, CAT LLC proposes to include the term 
``reasonably'' in the following sentence in Proposed Section 
11.3(a)(i)(B) of the CAT NMS Plan: ``For purposes of calculating CAT 
Fees, executed equivalent shares in a transaction in Eligible 
Securities will be reasonably counted as follows:''.
iii. 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 describe the budgeted CAT costs for calculating CAT 
Fees. It would state the following:

    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.

    As discussed above, CAT LLC also proposes to provide additional 
details regarding what is included in the annual operating budget 
approved by the Operating Committee pursuant to Section 11.1(a) of the 
CAT NMS Plan in proposed paragraphs (i) and (ii) of Section 11.1(a) of 
the CAT NMS Plan.
    Moreover, CAT LLC proposes to clarify that CAT Fees must be 
calculated using reasonably budgeted CAT costs. Accordingly, CAT 
proposes to include the terms ``reasonably'' and ``reasonable'' the 
following sentence: ``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.''
iv. 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. Each 
year, the Operating Committee would determine this projection based on 
the total executed equivalent share volume of transactions in Eligible 
Securities from the prior twelve months. Therefore, Proposed Section 
11.3(a)(i)(D) of the CAT NMS Plan would state that ``[t]he Operating 
Committee shall reasonably determine the projected total executed 
equivalent share volume of all transactions in Eligible Securities for 
each relevant period based on the executed equivalent share volume of 
all transactions in Eligible Securities for the prior twelve months.'' 
CAT LLC determined that the use of the data from the prior twelve 
months provides an appropriate balance between using data from a period 
that is sufficiently long to avoid short-term fluctuations while 
providing data close in time to the upcoming relevant period. 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

[[Page 44919]]

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 
projected total executed equivalent share volume of transactions in 
Eligible Securities. Accordingly, CAT LLC proposes to include the term 
``reasonably'' in the Proposed Section 11.3(a)(i)(D) of the CAT NMS 
Plan to indicate that the Operating Committee will ``reasonably 
determine the projected total executed equivalent share volume.''
c. Participant CAT Fees for Prospective CAT Costs
    CAT LLC proposes to describe the Participant CAT Fees related to 
Prospective CAT Costs in Proposed Section 11.3(a)(ii) of the CAT NMS 
Plan. Proposed Section 11.3(a)(ii) of the CAT NMS Plan would have two 
paragraphs (A) and (B), where paragraph (A) would describe the CAT Fee 
obligation for Participants and paragraph (B) would clarify that 
Participants would only be required to pay CAT Fees when Industry 
Members are required to pay CAT Fees.
i. CAT Fee Obligation of the Participants
    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. Specifically, proposed paragraph (A) of Proposed 
Section 11.3(a)(ii) of the CAT NMS Plan would state the following:

    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 reasonably determined pursuant to paragraph (a)(i) of this 
Section 11.3.

    CAT LLC intends for the Participant CAT Fee to be calculated using 
the Fee Rate reasonably determined pursuant to Proposed Section 
11.3(a)(i) of the CAT NMS Plan. Accordingly, CAT LLC proposes to 
include the term ``reasonably'' in the following sentence: ``[t]he 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 reasonably determined pursuant to 
paragraph (a)(i) of this Section 11.3.''
ii. Effectiveness of Participant CAT Fees
    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 Funding Proposal, 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. 
Accordingly, proposed paragraph (B) of Proposed Section 11.3(a)(ii) of 
the CAT NMS Plan would state that ``[e]ach Participant will be required 
to pay the CAT Fee calculated using the Fee Rate reasonably determined 
pursuant to paragraph (a)(i) of this Section 11.3 and approved by the 
Operating Committee only if such CAT Fees are in effect with regard to 
Industry Members in accordance with Section 19(b) of the Exchange 
Act.'' CAT LLC intends for the Participant CAT Fee to be calculated 
using the Fee Rate reasonably determined pursuant to Proposed Section 
11.3(a)(i) of the CAT NMS Plan. Accordingly, CAT LLC proposes to 
include the term ``reasonably'' in the phrase ``the Fee Rate reasonably 
determined'' in this provision.
d. Industry Member CAT Fees for Prospective CAT Costs
    CAT LLC proposes to describe the Industry Member CAT Fees related 
to Prospective CAT Costs in Proposed Section 11.3(a)(iii) of the CAT 
NMS Plan. Proposed Section 11.3(a)(iii) of the CAT NMS Plan would have 
three paragraphs, (A), (B) and (C), where paragraph (A) would describe 
the CAT Fee obligation for Industry Members, paragraph (B) would 
described the required content of the fee filings required to be filed 
pursuant to Section 19(b) of the Exchange Act regarding the CAT Fees 
for Industry Members, and paragraph (C) would clarify that Participants 
would not make CAT fee filings regarding CAT Fees until the Financial 
Accountability Milestone related to Period 4 as described in Section 
11.6 of the CAT NMS Plan has been satisfied.
i. Industry Member CAT Fee Obligation
    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. Accordingly, Proposed Section 
11.3(a)(iii)(A) of the CAT NMS Plan would state the following:

    Each Industry Member that is the CAT Executing Broker 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'') 
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.

    CAT LLC intends for the Participant CAT Fee to be calculated using 
the Fee Rate reasonably determined pursuant to Proposed Section 
11.3(a)(i) of the CAT NMS Plan. Accordingly, CAT LLC proposes to 
include the phrase ``the Fee Rate reasonably determined pursuant to 
paragraph (a)(i) of this Section 11.3'' in this provision.
ii. Fee Filings Under Section 19(b) of the Exchange Act for Industry 
Member CAT Fees
    CAT LLC proposes to describe 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 thereunder for Industry 
Member CAT Fees in proposed paragraph (B) of Proposed Section 
11.3(a)(iii) of the CAT NMS Plan.\43\ Specifically, such filings would 
be required 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, including (1) technology line items of cloud hosting services, 
operating fees, CAIS operating fees, change request fees and 
capitalized developed technology costs, (2) legal, (3)

[[Page 44920]]

consulting, (4) insurance, (5) professional and administration, and (6) 
public relations costs, a reserve and/or such other categories as 
reasonably determined by the Operating Committee to be included in the 
budget and the reason for changes in each such line item from the prior 
CAT Fee filing; \44\ (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. Such detailed information would 
provide Industry Members and other interested parties with a clear 
understanding of the calculation of the CAT Fees and their relationship 
to CAT costs.\45\
---------------------------------------------------------------------------

    \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 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.
    \44\ CAT LLC intends to include any other categories as 
reasonably determined by the Operation Committee. Accordingly, this 
provision refers to ``such other categories as reasonably determined 
by the Operating Committee to be included in the budget.''
    \45\ 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.
---------------------------------------------------------------------------

    In addition, CAT LLC proposes to clarify 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. Therefore, CAT LLC proposes to add the 
following sentence to Proposed Section 11.3(a)(iii)(B) of the CAT NMS 
Plan: ``The information provided in this Section would be provided with 
sufficient detail to demonstrate that the budget for the upcoming year, 
or part of year, as applicable, is reasonable and appropriate.''
iii. Financial Accountability Milestone
    CAT LLC recognizes that the collection of CAT Fees 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 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. Specifically, CAT LLC proposes 
to add proposed paragraph (C) to Proposed Section 11.3(a)(iii) to the 
CAT NMS Plan to address the Financial Accountability Milestone. This 
provision would state that ``[n]o Participant will make a filing with 
the SEC pursuant to Section 19(b) of the Exchange Act regarding any CAT 
Fee related to Prospective CAT Costs until the Financial Accountability 
Milestone related to Period 4 described in Section 11.6 has been 
satisfied.''
e. CAT Fee Details
    CAT LLC proposes to provide Participants and CAT Executing Brokers 
with details regarding the calculation of their CAT Fees upon request. 
Specifically, CAT LLC proposes to add Proposed Section 11.3(a)(iv)(A) 
to the CAT NMS Plan to describe this disclosure. This provision would 
state that ``[d]etails regarding the calculation of a Participant or 
CAT Executing Brokers' CAT Fees will be provided upon request to such 
Participant or CAT Executing Broker. At a minimum, such details would 
include each Participant or CAT Executing Broker's executed equivalent 
share volume and corresponding fee by (1) Listed Options, NMS Stocks 
and OTC Equity Securities, (2) by transactions executed on each 
exchange and transactions executed otherwise than on an exchange, and 
(3) by buy-side transactions and sell-side transactions.'' Such 
information would provide Participants and CAT Executing Brokers with 
the ability to understand the details regarding the calculation of 
their CAT Fees.
    In addition, CAT LLC proposes to make certain aggregate statistics 
regarding the CAT Fees publicly available. Specifically, CAT LLC 
proposes to add Proposed Section 11.3(a)(iv)(B) to the CAT NMS Plan to 
describe this public disclosure. This provision would state that 
``[f]or each CAT Fee, at a minimum, CAT LLC will make publicly 
available the aggregate executed equivalent share volume and 
corresponding aggregate fee by (1) Listed Options, NMS Stocks and OTC 
Equity Securities, (2) by transactions executed on each exchange and 
transactions executed otherwise than on an exchange, and (3) by buy-
side transactions and sell-side transactions.'' \46\

4. Historical CAT Assessment
    CAT LLC proposes to describe Historical CAT Assessments related to 
Historical CAT Costs in Proposed Section 11.3(b) of the CAT NMS Plan. 
Proposed Section 11.3(b) of the CAT NMS Plan would describe that 
Historical CAT Assessments apply only to Industry Members (not to 
Participants), the manner of calculating the Historical Fee Rate for 
the Historical CAT Assessment, a description of the calculation of the 
Industry Member CAT Fees, a description of the fee filings under 
Section 19(b) of the Exchange Act for Historical CAT Assessments, and 
details regarding the calculation of the Historical CAT Assessments 
that are available upon request or publicly available. The following 
describes in detail Section 11.3(b) of the CAT NMS Plan.
a. Introductory Statement
    CAT LLC proposes to revise Section 11.3(b) of the CAT NMS Plan to 
address Historical CAT Assessments related to Historical CAT Costs to 
be charged to Industry Members. Accordingly, CAT LLC proposes to revise 
the introductory statement in Proposed Section 11.3(b) of the CAT NMS 
Plan to state that ``[t]he Operating Committee will establish one or 
more fees (each a ``Historical CAT Assessment'') to be payable by 
Industry Members with regard to CAT costs previously paid by the 
Participants (``Past CAT Costs'') as follows:''.\47\ With the reference 
to ``one or more'' Historical CAT Fees, this provision also clarifies 
that there may be one or more Historical CAT Assessments.
---------------------------------------------------------------------------

    \47\ To date, there has been one Historical CAT Assessment, 
referred to as Historical CAT Assessment 1. See, e.g., Securities 
Exchange Act Rel. No. 100936 (Sept. 5, 2024), 89 FR 74430 (Sept. 22, 
2024) (BOX Exchange LLC filing for Historical CAT Assessment 1). 
There may be one or more additional Historical CAT Assessments 
related to CAT costs incurred prior to the completion of the fourth 
and final Financial Accountability Milestone (``FAM 4'') in July 
2024.
---------------------------------------------------------------------------

b. Calculation of Historical Fee Rate
    CAT LLC proposes to provide details regarding the calculation of 
the Historical CAT Assessment in Proposed Section 11.3(b)(i) of the CAT 
NMS Plan. These details would include a description of the calculation 
of the Historical Fee Rate, the counting method for executed equivalent 
shares, the Historical CAT Costs, the Historical Recovery Period, and 
the projected total executed equivalent share volume of transactions in 
Eligible Securities for the Historical Recovery Period.
i. General
    Proposed paragraph (a) of Proposed Section 11.3(b)(i) of the CAT 
NMS Plan would describe the calculation of the Historical Fee Rate for 
each Historical CAT Assessment and the requirement for Participants to 
file a fee filing for each Historical CAT Assessment. This proposed 
provision also would state that Industry Members would be

[[Page 44921]]

required to pay each Historical CAT Assessment once such Historical CAT 
Assessment is in effect in accordance with Section 19(b) of the 
Exchange Act. Specifically, this proposed provision 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 SEC 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.

    CAT LLC proposes to clarify that the calculation of each Historical 
Fee Rate would be performed using reasonably projected total executed 
equivalent share volume. Accordingly, CAT LLC proposes to use the term 
``reasonably'' to the describe ``projected total executed equivalent 
share volume'' in this provision.
ii. Executed Equivalent Shares
    The Historical CAT Assessment would be calculated based on the same 
executed equivalent share calculation as CAT Fees related to 
Prospective CAT Costs. Accordingly, Proposed Section 11.3(b)(i)(B) of 
the CAT NMS Plan would make it clear that the calculation is the same 
for both types of fees. Specifically, Proposed Section 11.3(b)(i)(B) of 
the CAT NMS Plan would state that ``[f]or purposes of calculating each 
Historical CAT Assessment, executed equivalent shares in a transaction 
in Eligible Securities will be reasonably counted in the same manner as 
set forth in paragraph (a)(i)(B) of this Section 11.3.''
iii. Historical CAT Costs
    The calculation of the Historical CAT Assessment depends upon the 
determination of the 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. The Operating 
Committee will reasonably determine the Past CAT Costs sought to be 
recovered through the Historical CAT Assessment. CAT LLC proposes to 
make this approach clear in the language of the CAT NMS Plan by adding 
Proposed Section 11.3(b)(i)(C) of the CAT NMS Plan, which 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.''
    CAT LLC proposes to further clarify the amount to be collected via 
the Historical CAT Assessments in Proposed Section 11.3(b)(i)(C) of the 
CAT NMS Plan. Specifically, CAT LLC proposes to add the clarifying 
statement 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.'' This 
statement reiterates the requirement set forth in Proposed Section 
11.3(b)(iii)(A) of the CAT NMS Plan regarding the calculation of the 
Historical CAT Assessment, which requires the multiplication of the 
number of executed equivalent shares in the transaction by one-third 
and by the Historical Fee Rate. Each CEBS and CEBB pays one-third, and, 
therefore, two-thirds of the Historical CAT Costs would be collected 
from CAT Executing Brokers.
    CAT LLC also proposes to add the term ``reasonably'' to the 
following sentence in Section 11.1(c) of the CAT NMS Plan before the 
word ``incurred'': ``In determining fees on Participants and Industry 
Members the Operating Committee shall take into account fees, costs and 
expenses (including legal and consulting fees and expenses) reasonably 
incurred by the Participants on behalf of the Company prior to the 
Effective Date in connection with the creation and implementation of 
the CAT.'' The addition of the term ``reasonably'' would require such 
fees, costs and expenses to be reasonable.
iv. Historical Recovery Period
    The calculation of the Historical CAT Assessment also depends upon 
the determination of the Historical Recovery Period. Based on CAT costs 
incurred to date, however, CAT LLC believes that the Historical 
Recovery Period should not be less than 24 months or more than five 
years.\48\ In analyzing the potential Historical Recovery Periods, CAT 
LLC sought to weigh the need for a reasonable Historical Fee Rate that 
spreads the Historical CAT Costs over an appropriate amount of time and 
the need to repay the loan notes to the Participants in a timely 
fashion. Based on an analysis of the Historical CAT Costs and executed 
equivalent share volume of transactions in Eligible Securities to date, 
CAT LLC determined that the Historical Fee Rate calculated using a 
Historical Recovery Period of two to five years would establish a 
reasonable Historical Fee Rate even if Industry Members were required 
to pay a Historical CAT Assessment and the ongoing CAT Fee at the same 
time. CAT LLC notes, however, that the actual Historical CAT Assessment 
would be calculated using Historical CAT Costs to be recovered for such 
Historical CAT Assessment and executed equivalent share volume.
---------------------------------------------------------------------------

    \48\ CAT LLC 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, e.g., Securities Exchange Act Rel. 
No. 100936 (Sept. 5, 2024), 89 FR 74430 (Sept. 22, 2024) (BOX 
Exchange LLC filing for Historical CAT Assessment 1).
---------------------------------------------------------------------------

    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.'' \49\ 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.'' As discussed below, the Historical 
Recovery Period is used to calculate the Historical Fee Rate. The 
actual recovery period may be longer or shorter than the Historical 
Recovery Period depending on the actual executed equivalent share 
volumes during the time that the Historical CAT Assessment is in 
effect. Any Historical CAT Assessment would remain in effect until the 
relevant Historical CAT Costs are recovered, whether that time is 
shorter or longer than the Historical Recovery Period used in 
calculating the Historical Fee Rate.
---------------------------------------------------------------------------

    \49\ This provision would require that the Historical Recovery 
Period be ``reasonably'' established by the Operating Committee.
---------------------------------------------------------------------------

    Proposed Section 11.3(b)(i)(D)(II) of the CAT NMS Plan would 
describe the length of the time that the Historical CAT Assessment 
would be in effect, which may be greater than or less than the 
Historical Recovery Period, depending on the amount of the Historical 
CAT Assessments collected based on the actual volume during the time 
that the Historical Assessment is in effect. Any Historical CAT 
Assessment

[[Page 44922]]

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. 
Accordingly, this provision states that ``[n]otwithstanding the length 
of the Historical Recovery Period used in calculating the Historical 
Fee Rate, each Historical CAT Assessment calculated using the 
Historical Fee Rate will remain in effect until all Historical CAT 
Costs for the Historical CAT Assessment are collected.''
v. 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. CAT LLC proposes to 
clarify the manner of calculating the projected total executed 
equivalent share volume for each Historical CAT Assessment in Proposed 
Section 11.3(b)(i)(E) to the CAT NMS Plan. CAT LLC proposes to state in 
this provision that the projection will be determined based on 
transactions in Eligible Securities for the prior twelve months. 
Accordingly, Proposed Section 11.3(b)(i)(E) of the CAT NMS Plan would 
state that ``[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.'' As with the calculation of 
the projections for CAT Fees, CAT LLC determined that the use of the 
data from the prior twelve months provides an appropriate balance 
between using data from a period that is sufficiently long to avoid 
short-term fluctuations while providing data close in time to the 
upcoming relevant period. 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. As noted, 
this provision would require the Operating Committee to ``reasonably'' 
determine the projected total executed equivalent share volume.
c. 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. 
It would state that, ``[b]ecause Participants previously have paid Past 
CAT Costs via loans to the Company, Participants would not be required 
to pay any Historical CAT Assessment.'' In addition, Proposed Section 
11.3(b)(ii) of the CAT NMS Plan would clarify that the Historical CAT 
fees collected from Industry Members would be allocated to Participants 
for repayment of the outstanding loan notes of the Participants to the 
Company on a pro rata basis; such fees would not be allocated to 
Participants based on the executed equivalent share volume of 
transactions in Eligible Securities. Specifically, 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 
``Historical CAT Assessments are designed to recover two-thirds of the 
Historical CAT Costs.''
d. Historical CAT Assessment for Industry Members
    CAT LLC proposes to describe the Historical CAT Assessment for 
Industry Members in Proposed Section 11.3(b)(iii) of the CAT NMS Plan. 
Proposed Section 11.3(b)(iii) of the CAT NMS Plan would have two 
paragraphs, (A) and (B), where paragraph (A) would describe the 
Historical CAT Assessment for Industry Members, and paragraph (B) would 
describe the fee filings required to be filed pursuant to Section 19(b) 
of the Exchange Act regarding the Historical CAT Assessments.
i. Industry Member Obligation for Historical CAT Assessment
    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. Specifically, this proposed paragraph would state that:

    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.

    As noted, this provision would require the Operating Committee to 
``reasonably'' determine the Historical Fee Rate pursuant to Proposed 
Section 11.3(b)(i) of the CAT NMS Plan.
ii. Historical CAT Assessment Fee Filings
    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.\50\ Specifically, this 
provision would describe that fee filings would be required for each 
Historical CAT Assessment, the content of such fee filings, and the 
effect of the Financial Accountability Milestones described in Section 
11.6 of the CAT NMS Plan on the fee filings.
---------------------------------------------------------------------------

    \50\ 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.
---------------------------------------------------------------------------

A. Number of Fee Filings for Historical CAT Assessments
    CAT LLC proposes to clarify how many fee filings pursuant to 
Section 19(b) of the Exchange Act Participants would be required to 
make with regard to Historical CAT Assessments. CAT LLC proposes to 
clarify 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. Accordingly, CAT LLC proposes to describe 
this requirement in Proposed Section 11.3(b)(iii)(B)(I) of the CAT NMS 
Plan, which would state that ``Participants will be required to file 
with the SEC pursuant to Section 19(b) of the Exchange Act a filing for 
each Historical CAT Assessment.''

B. Content of Fee Filings for Historical CAT Assessments

    CAT LLC proposes to provide additional detail as to 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

[[Page 44923]]

Plan. The proposed paragraph sets forth the information about the 
Historical CAT Assessments that should be included in the fee filings 
required to be made by the Participants pursuant to Section 19(b) of 
the Exchange Act. 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. Such detailed information would provide 
Industry Members and other interested parties with a clear 
understanding of the calculation of each Historical CAT Assessment and 
its relationship to Historical CAT Costs.\51\
---------------------------------------------------------------------------

    \51\ 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.
---------------------------------------------------------------------------

    In addition, CAT LLC proposes to clarify that the Historical CAT 
Costs described in the fee filings must provide sufficient detail to 
demonstrate that such costs are reasonable and appropriate. Therefore, 
CAT LLC proposes to add the following sentence to Proposed Section 
11.3(b)(iii)(B)(II) of the CAT NMS Plan: ``The information provided in 
this Section would be provided with sufficient detail to demonstrate 
that the Historical CAT Costs are reasonable and appropriate.''
C. Financial Accountability Milestones
    CAT LLC recognizes that 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 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. Specifically, CAT LLC 
proposes to add Proposed Section 11.3(b)(iii)(B)(III) to the CAT NMS 
Plan. This provision would state that ``[n]o Participant will make a 
filing with the SEC pursuant to Section 19(b) of the Exchange Act 
regarding any Historical CAT Assessment until any applicable Financial 
Accountability Milestone described in Section 11.6 has been 
satisfied.''
e. Historical CAT Assessment Details
    CAT LLC proposes to provide CAT Executing Brokers with details 
regarding the calculation of their Historical CAT Assessments upon 
request. Specifically, CAT LLC proposes to add Proposed Section 
11.3(b)(iv)(A) to the CAT NMS Plan, which would state that ``[d]etails 
regarding the calculation of a CAT Executing Broker's Historical CAT 
Assessment will be provided upon request to such CAT Executing Broker. 
At a minimum, such details would include each CAT Executing Broker's 
executed equivalent share volume and corresponding fee by (1) Listed 
Options, NMS Stocks and OTC Equity Securities, (2) by transactions 
executed on each exchange and transactions executed otherwise than on 
an exchange, and (3) by buy-side transactions and sell-side 
transactions.'' Such information would provide CAT Executing Brokers 
with the ability to understand the details regarding the calculation of 
their Historical CAT Assessments.
    In addition, CAT LLC proposes to make certain aggregate statistics 
regarding Historical CAT Assessments publicly available. Specifically, 
CAT LLC proposes to add Proposed Section 11.3(b)(iv)(B) to the CAT NMS 
Plan. This provision would state that ``[f]or each Historical CAT 
Assessment, at a minimum, CAT LLC will make publicly available the 
aggregate executed equivalent share volume and corresponding aggregate 
fee by (1) Listed Options, NMS Stocks and OTC Equity Securities, (2) by 
transactions executed on each exchange and transactions executed 
otherwise than on an exchange, and (3) by buy-side transactions and 
sell-side transactions.''
5. Participant Pass-Through Fees
    CAT LLC proposes to add a new paragraph (e) to Section 11.3 to 
address the Eleventh Circuit's opinion regarding the potential for 
Participants to pass-through 100% of their CAT fees to Industry 
Members, and its effect on the allocation of CAT costs under the 
Executed Share Model. Proposed new paragraph (e) of Section 11.3 would 
state that ``[e]ach Participant agrees not to file with the SEC a 
proposed rule change pursuant to Section 19(b) 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).'' \52\ This proposed provision would respond to the 
Eleventh Circuit's decision regarding the possibility for Participants 
to pass-through their CAT fees to their members, thereby causing 
Industry Members to bear more than two-thirds of the CAT costs 
(ignoring what Industry Members would pass-through to investors).
---------------------------------------------------------------------------

    \52\ As highlighted in Exhibit B, Proposed Section 11.3(e) of 
the CAT NMS Plan was not included in the Executed Share Model.
---------------------------------------------------------------------------

6. 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 Funding Proposal. 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.''
7. Additional Changes From Original Funding Model
    CAT LLC proposes certain revisions to Article XI of the CAT NMS 
Plan to implement the Funding Proposal. CAT LLC proposes to make the 
following changes to the CAT NMS Plan in addition to the proposed 
changes to the CAT NMS Plan discussed above.
a. Elimination of Definition of ``Execution Venue''
    Section 1.1 of the CAT NMS Plan defines the term ``Execution 
Venue'' to mean ``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).'' Currently, the term ``Execution Venue'' is 
used in Sections 11.2 and 11.3 of the CAT NMS Plan to describe how CAT 
costs would be allocated among CAT Reporters under the Original Funding 
Model. The Original Funding Model would have imposed fees based on 
market share to CAT Reporters that are Execution Venues, including 
ATSs, and fees based on message traffic for Industry Members' non-ATS 
activities. In contrast, the Funding Proposal would impose fees based 
on the executed equivalent shares of transactions in

[[Page 44924]]

Eligible Securities for three categories of CAT Reporters: 
Participants, CEBBs and CEBSs. Accordingly, as the concept for an 
``Execution Venue'' would not be relevant for the Funding Proposal, CAT 
LLC proposes to delete this term and its definition from Section 1.1 of 
the CAT NMS Plan.
b. Use of Executed Equivalent Share Volume Under Funding Proposal
    The Original Funding Model set forth in the CAT NMS Plan requires 
Participants and Execution Venue ATSs to pay CAT fees based on market 
share and Industry Members (other than Execution Venue ATSs) to pay CAT 
fees based on message traffic. The CAT NMS Plan also describes how the 
market share-based fee would be calculated for Participants and other 
Execution Venue ATSs and how the message traffic-based fee would be 
calculated for Industry Members (other than Execution Venue ATSs). CAT 
LLC proposes to amend the CAT NMS Plan to require Participants, CEBBs 
and CEBSs to pay CAT fees based on the number of executed equivalent 
shares in a transaction in Eligible Securities, rather than based on 
market share and message traffic. Accordingly, the Operating Committee 
proposes to amend Section 11.2(b) and (c) and Section 11.3(a) and (b) 
of the CAT NMS Plan to reflect the proposed use of the number of 
executed equivalent shares in transactions in Eligible Securities in 
calculating CAT fees.
    Section 11.2(b) of the CAT NMS Plan states that ``[i]n establishing 
the funding of the Company, the Operating Committee shall seek . . . 
(b) to establish an allocation of the Company's related costs among 
Participants and Industry Members that is consistent with the Exchange 
Act, taking into account the timeline for implementation of the CAT and 
distinctions in the securities trading operations of Participants and 
Industry Members and their relative impact upon Company resources and 
operations.'' CAT LLC proposes to delete the requirement to take into 
account ``distinctions in the securities trading operations of 
Participants and Industry Members and their relative impact upon 
Company resources and operations.'' This requirement related to using 
message traffic and market share in the calculation of CAT fees, as 
message traffic and market share were metrics related to the impact of 
a CAT Reporter on the Company's resources and operations. With the 
proposed move to the use of the executed equivalent shares metric 
instead of message traffic and market share, the requirement is no 
longer relevant.
    Section 11.2(c) of the CAT NMS Plan states that ``[i]n establishing 
the funding of the Company, the Operating Committee shall seek . . . 
(c) to establish a tiered fee structure in which the fees charged to: 
(i) CAT Reporters that are Execution Venues, including ATSs, are based 
upon the level of market share; (ii) Industry Members' non-ATS 
activities are based upon message traffic.'' CAT LLC proposes to delete 
subparagraphs (i) and (ii) and replace these subparagraphs with the 
requirement that the fee structure in which the fees charged to 
``Participants and Industry Members are based upon the executed 
equivalent share volume of transactions in Eligible Securities.'' \53\
---------------------------------------------------------------------------

    \53\ As discussed in the next section, the Operating Committee 
also proposes to delete the reference to a ``tiered'' fee structure.
---------------------------------------------------------------------------

    In addition, CAT LLC proposes to amend the CAT funding principles 
to clarify that CAT Fees and the Historical CAT Assessments are 
intended to be cost-based fees--that is, the fees are designed to 
recover the cost of the creation, implementation and operation of the 
CAT. CAT LLC proposes to amend the funding principle set forth in 
Section 11.2(c) by making a specific reference to the costs of the CAT. 
With this proposed change, Proposed Section 11.2(c) would state that 
``[i]n establishing the funding of the Company, the Operating Committee 
shall seek: . . . to establish a fee structure in which the fees 
charged to Participants and Industry Members are based upon the 
executed equivalent share volume of transactions in Eligible 
Securities, and the costs of the CAT.''
    Section 11.3(a) of the CAT NMS Plan provides additional detail 
regarding the market share-based fees to be paid by Participants and 
Execution Venue ATSs under the Original Funding Model. Specifically, 
Section 11.3(a) of the CAT NMS Plan states:

    (a) The Operating Committee will establish fixed fees to be 
payable by Execution Venues as provided in this Section 11.3(a):
    (i) Each Execution Venue that: (A) executes transactions; or (B) 
in the case of a national securities association, has trades 
reported by its members to its trade reporting facility or 
facilities for reporting transactions effected otherwise than on an 
exchange, in NMS Stocks or OTC Equity Securities will pay a fixed 
fee depending on the market share of that Execution Venue in NMS 
Stocks and OTC Equity Securities, with the Operating Committee 
establishing at least two and no more than five tiers of fixed fees, 
based on an Execution Venue's NMS Stocks and OTC Equity Securities 
market share. For these purposes, market share for Execution Venues 
that execute transactions will be calculated by share volume, and 
market share for a national securities association that has trades 
reported by its members to its trade reporting facility or 
facilities for reporting transactions effected otherwise than on an 
exchange in NMS Stocks or OTC Equity Securities will be calculated 
based on share volume of trades reported, provided, however, that 
the share volume reported to such national securities association by 
an Execution Venue shall not be included in the calculation of such 
national security association's market share.
    (ii) Each Execution Venue that executes transactions in Listed 
Options will pay a fixed fee depending on the Listed Options market 
share of that Execution Venue, with the Operating Committee 
establishing at least two and no more than five tiers of fixed fees, 
based on an Execution Venue's Listed Options market share. For these 
purposes, market share will be calculated by contract volume.

    CAT LLC proposes to delete Section 11.3(a) of the CAT NMS Plan and 
replace this paragraph with a description of the CAT Fees related to 
Prospective CAT Costs, as described above.
    Section 11.3(b) of the CAT NMS Plan provides additional detail 
regarding the message traffic-based CAT fees to be paid by Industry 
Members (other than Execution Venue ATSs) under the Original Funding 
Model. Specifically, Section 11.3(b) of the CAT NMS Plan states:

    The Operating Committee will establish fixed fees to be payable 
by Industry Members, based on the message traffic generated by such 
Industry Member, with the Operating Committee establishing at least 
five and no more than nine tiers of fixed fees, based on message 
traffic. For the avoidance of doubt, the fixed fees payable by 
Industry Members pursuant to this paragraph shall, in addition to 
any other applicable message traffic, include message traffic 
generated by: (i) an ATS that does not execute orders that is 
sponsored by such Industry Member; and (ii) routing orders to and 
from any ATS sponsored by such Industry Member.

    CAT LLC proposes to delete Section 11.3(b) of the CAT NMS Plan and 
replace this paragraph with a description of the Historical CAT 
Assessments, as described above.
c. Elimination of Tiered Fees
    CAT LLC proposes to eliminate the use of tiered fees that were 
included in the Original Funding Model. Instead, under the Funding 
Proposal, each Participant, CEBB or CEBS would pay a fee based solely 
on its transactions in Eligible Securities. The Operating Committee 
therefore proposes to amend Sections 11.1(d), 11.2(c), 11.3(a) and 
11.3(b) of the CAT NMS Plan to eliminate tiered fees and related 
concepts.
    Utilizing a tiered fee structure, by its nature, would create 
certain inequities

[[Page 44925]]

among the CAT fees paid by CAT Reporters. For example, two CAT 
Reporters with comparable executed equivalent share volume may pay 
notably different fees if one falls in a higher tier and the other 
falls within a lower tier. Correspondingly, a tiered fee structure 
generally would reduce fees for CAT Reporters with higher executed 
share volume in one tier, while increasing fees for Industry Members 
with lower executed share volume in the same tier, as compared to a 
non-tiered fee. Furthermore, CAT Reporters in lower tiers potentially 
pay more than they would without the use of tiers. While tiering 
appropriately exists in various other self-regulatory fee programs, CAT 
LLC proposes to eliminate the tiering concept for the Funding Proposal.
    By charging each Participant, CEBB and CEBS a CAT fee directly 
based on its own executed equivalent share volume, rather than charging 
a tiered fee, the Funding Proposal would result in a CAT fee being tied 
more directly to the CAT Reporter's executed share volume. In contrast, 
with a tiered fee, CAT Reporters with different levels of executed 
equivalent share volume that are placed in the same tier would all pay 
the same CAT fee, thereby limiting the correlation between a CAT 
Reporter's activity and its CAT fee.
    The proposed non-tiering approach is simpler and more objective to 
administer than the tiering approach. With a tiering approach, the 
number of tiers for Participants, CEBBs and CEBSs, the boundaries for 
each tier and the fees assigned to each tier must be established. In 
the absence of clear groupings of CAT Reporters, selecting the number 
of, boundaries for, and the fees associated with each tier would be 
subject to some level of subjectivity. Furthermore, the establishment 
of tiers would need to be continually reassessed based on changes in 
the executed equivalent share volume of transactions in Eligible 
Securities, thereby requiring regular subjective assessments. 
Accordingly, the removal of tiering from the Funding Proposal 
eliminates a variety of subjective analyses and judgments from the 
model and simplifies the determination of CAT fees.
    Section 11.1(d) of the CAT NMS Plan states that ``[c]onsistent with 
this Article XI, the Operating Committee shall adopt policies, 
procedures, and practices regarding the budget and budgeting process, 
assignment of tiers, resolution of disputes, billing and collection of 
fees, and other related matters.'' With the elimination of tiered fees, 
the reference to the ``assignment of tiers'' would no longer be 
relevant for the Funding Proposal. Therefore, CAT LLC proposes to 
delete the reference to ``assignment of tiers'' from Section 11.1(d).
    Section 11.1(d) of the CAT NMS Plan also states that:

    For the avoidance of doubt, as part of its regular review of 
fees for the CAT, the Operating Committee shall have the right to 
change the tier assigned to any particular Person in accordance with 
fee schedules previously filed with the Commission that are 
reasonable, equitable and not unfairly discriminatory and subject to 
public notice and comment, pursuant to this Article XI. Any such 
changes will be effective upon reasonable notice to such Person.

    As noted above, unlike the Original Funding Model, the Funding 
Proposal would not utilize tiered fees. Accordingly, these two 
sentences would not be applicable to the Funding Proposal. Therefore, 
CAT LLC proposes to delete these two sentences from Section 11.1(d) of 
the CAT NMS Plan.
    CAT LLC proposes to delete the reference to ``tiered'' fees from 
Section 11.2(c) of the CAT NMS Plan. Section 11.2(c) of the CAT NMS 
Plan states that ``[i]n establishing the funding of the Company, the 
Operating Committee shall seek: . . . (c) to establish a tiered fee 
structure . . .'' CAT LLC propose to delete the word ``tiered'' from 
this provision as the CAT fees would not be tiered under the Funding 
Proposal.
    CAT LLC also proposes to delete paragraph (iii) of Section 11.2(c) 
of the CAT NMS Plan. Paragraph (iii) of Section 11.2(c) of the CAT NMS 
Plan states that the Operating Committee shall seek to establish a 
tiered fee structure in which fees charged to:

the CAT Reporters with the most CAT-related activity (measured by 
market share and/or message traffic, as applicable) be 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).

    Under the Original Funding Model, the comparability provision was 
an important factor in determining the tiers for Industry Members and 
Execution Venues. In determining the tiers, the Operating Committee 
sought to establish comparable fees among the CAT Reporters with the 
most Reportable Events.\54\ Under the Funding Proposal, however, the 
comparability provision is no longer necessary, as a tiered fee 
structure would not be used for Industry Members or Participants.
---------------------------------------------------------------------------

    \54\ See, e.g., Securities Exchange Act Rel. No. 82451 (Jan. 5, 
2018), 83 FR 1399, 1406-07 (Jan. 11, 2018) (``2018 Fee Proposal 
Release'').
---------------------------------------------------------------------------

    As discussed above, the Operating Committee proposes to replace the 
language in Sections 11.3(a) and (b) of the CAT NMS Plan with language 
implementing the Funding Proposal. These proposed changes would remove 
the references to tiers in Sections 11.3(a)(i) and (ii) and 11.3(b) of 
the CAT NMS Plan, along with the other proposed changes. Specifically, 
Section 11.3(a)(i) of the CAT NMS Plan states that the Operating 
Committee, when establishing fees for Execution Venues for NMS Stocks 
and OTC Equity Securities, will establish ``at least two and no more 
than five tiers of fixed fees, based on an Execution Venue's NMS Stocks 
and OTC Equity Securities market share.'' Similarly, Section 
11.3(a)(ii) of the CAT NMS Plan states that the Operating Committee, 
when establishing fees for Execution Venues that execute transactions 
in Listed Options, will establish ``at least two and no more than five 
tiers of fixed fees, based on an Execution Venue's Listed Options 
market share.'' Section 11.3(b) of the CAT NMS Plan states that the 
Operating Committee, when establishing fees to be payable by Industry 
Members, will establish ``at least five and no more than nine tiers of 
fixed fees, based on message traffic.'' CAT LLC proposes to delete each 
of these references to tiers from the CAT NMS Plan.
d. No Fixed Fees
    As discussed above, CAT LLC proposes to replace the language in 
Sections 11.3(a) and (b) of the CAT NMS Plan with language implementing 
the Funding Proposal. These proposed changes also would remove the 
references to ``fixed fees'' in Sections 11.3(a), 11.3(a)(i), 
11.3(a)(ii) and 11.3(b) and replaced them with references to ``fees.'' 
Under the Funding Proposal, the CAT fees to be paid by Participants, 
CEBBs and CEBSs will vary in accordance with their executed equivalent 
share volume of transactions in Eligible Securities, although the Fee 
Rate will be fixed for a relevant period. Therefore, the concept of a 
fixed fee--that is, a fee that does not vary depending on 
circumstances--is not relevant under the Funding Proposal.
8. Billing and Collection of CAT Fees
    Consistent with Section 11.1(d) of the CAT NMS Plan, CAT LLC will 
adopt policies, procedures and practices regarding the billing and 
collection of fees. In addition, pursuant to Section 11.4 of the CAT 
NMS Plan, CAT LLC will establish a system for the collection of CAT 
fees from Participants and Industry Members. As set forth in

[[Page 44926]]

Section 11.4 of the CAT NMS Plan, each Participant would be required to 
pay its CAT fees authorized under the CAT NMS Plan as required by 
Section 3.7(b) of the CAT NMS Plan.\55\ Section 3.7(b) of the CAT NMS 
Plan provides the following:
---------------------------------------------------------------------------

    \55\ Participants and CAT Executing Brokers would be responsible 
for a fee each month in which they are a CAT Reporter. If a 
Participant or CAT Executing Broker ceases to the meet the 
definition of a CAT Reporter during a month, the Participant or CAT 
Executing Broker would still be responsible for CAT fees associated 
with its transactions during that month.

    Each Participant shall pay all fees or other amounts required to 
be paid under this Agreement within thirty (30) days after receipt 
of an invoice or other notice indicating payment is due (unless a 
longer payment period is otherwise indicated) (the ``Payment 
Date''). The Participant shall pay interest on the outstanding 
balance from the Payment Date until such fee or amount is paid at a 
per annum rate equal to the lesser of: (i) the Prime Rate plus 300 
basis points; or (ii) the maximum rate permitted by applicable law. 
If any such remaining outstanding balance is not paid within thirty 
(30) days after the Payment Date, the Participants shall file an 
amendment to this Agreement requesting the termination of the 
participation in the Company of such Participant, and its right to 
any Company Interest, with the SEC. Such amendment shall be 
effective only when it is approved by the SEC in accordance with SEC 
---------------------------------------------------------------------------
Rule 608 or otherwise becomes effective pursuant to SEC Rule 608.

    Section 11.4 of the CAT NMS Plan also addresses the payment of CAT 
fees by Industry Members. Section 11.4 of the CAT NMS Plan states:

    Participants shall require each Industry Member to pay all 
applicable fees authorized under this Article XI within thirty (30) 
days after receipt of an invoice or other notice indicating payment 
is due (unless a longer payment period is otherwise indicated). If 
an Industry Member fails to pay any such fee when due (as determined 
in accordance with the preceding sentence), such Industry Member 
shall pay interest on the outstanding balance from such due date 
until such fee is paid at a per annum rate equal to the lesser of: 
(a) the Prime Rate plus 300 basis points; or (b) the maximum rate 
permitted by applicable law.
9. Advantages of and Support for the Funding Proposal
    CAT LLC proposes to adopt the Funding Proposal as it provides a 
variety of advantages over the Original Funding Model. CAT LLC 
discusses these advantages in this section of the filing.
a. Comparable to Existing Fee Precedent
    The Funding Proposal would operate in a manner similar to other 
funding models employed by the SEC and the Participants, including the 
SEC's Section 31 fees, FINRA's trading activity fee (``FINRA TAF'') and 
the options regulatory fee (``ORF'') utilized by options exchanges. The 
SEC previously has determined that the Participants' sales value fees 
related to Section 31, the FINRA TAF and the ORF are consistent with 
the Exchange Act.
i. Section 31 Fees
    Pursuant to Section 31 of the Exchange Act, a national securities 
exchange must pay the Commission a fee based on the aggregate dollar 
amount of sales of securities transacted on the exchange, and a 
national securities association must pay the Commission a fee based on 
the aggregate dollar amount of sales of securities transacted by or 
through any member of the association otherwise than on a national 
securities exchange (collectively, ``covered sales''). The SEC 
calculates the amount of Section 31 fees due from each exchange or 
FINRA by multiplying the aggregate dollar amount of its covered sales 
by the fee rate set by the Commission in a procedure set forth in 
Section 31(j) of the Exchange Act. These fees are designed to recover 
the costs related to the government's supervision and regulation of the 
securities markets and securities professionals. Section 31 requires 
the SEC to make annual and, in some cases, mid-year adjustments to the 
fee rate. These adjustments are necessary to make the SEC's total 
collection of transaction fees in a given year as close as possible to 
the amount of the regular appropriation to the Commission by Congress 
for that fiscal year.
    To recover the costs of their Section 31 fee obligations, each of 
the national securities exchanges and FINRA have adopted, and the SEC 
has approved, rules assessing a regulatory transaction fee on their 
members, the amount of which is set in accordance with Section 31 of 
the Exchange Act.\56\ Broker-dealers, in turn, often impose fees on 
their customers that provide the funds to pay the fees owed to the 
exchanges and FINRA.
---------------------------------------------------------------------------

    \56\ See, e.g., Section 3 of Schedule A of FINRA's By-Laws.
---------------------------------------------------------------------------

    Like the well-known, longstanding and accepted Section 31-related 
fee model, the Funding Proposal would use a predetermined fee rate for 
the calculation of the fees, seek to recover designated regulatory 
costs (as CAT provides a solely regulatory function), and allow for the 
adjustment of the fee rate during the year to seek to match regulatory 
costs with fees collected. The Funding Proposal, however, would impose 
fees based on executed equivalent share volume rather than the sales 
values of certain transactions. Despite the different calculation 
metric, the Funding Proposal is similar to a model well-known, long 
accepted and justified under the Exchange Act the purpose of which is 
also to cover costs associated with the regulation of securities 
markets and securities professionals.
ii. FINRA Trading Activity Fee
    The transaction-based fees charged under the Funding Proposal also 
would be similar to FINRA's transaction-based trading activity fee,\57\ 
which was modeled on the Commission's Section 31 fee.\58\ Although the 
FINRA TAF is designed to cover a subset of the costs of FINRA services 
(e.g., costs to FINRA of the supervision and regulation of members, 
including performing examinations, financial monitoring, and policy, 
rulemaking, interpretive, and enforcement activities) rather than all 
of FINRA's costs like the CAT, the transaction-based calculation of the 
FINRA TAF and the proposed CAT fees are similar. With the FINRA TAF, 
FINRA members on the sell-side of a transaction are required to pay a 
per share fee for each sale of covered securities, which includes 
exchange registered securities, equity securities traded otherwise than 
on an exchange, security futures, TRACE-Eligible Securities and 
municipal securities, subject to certain exceptions. In approving the 
FINRA TAF, the SEC stated that the implementation of the FINRA TAF ``is 
consistent with section 15A(b)(5) of the Act, in that the proposal is 
reasonably designed to recover NASD costs related to regulation and 
oversight of its members.'' \59\ The SEC further stated that ``[t]he 
Commission recognizes the difficulties inherent in restructuring the 
NASD's regulatory fees, and believes that the NASD has done so in a 
manner that is fair and reasonable.'' \60\ The CAT fees calculated 
under the Funding Proposal would be similar to the FINRA TAF in that 
they would be transaction-based fees intended to provide funding for 
regulatory costs.

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

iii. Options Regulatory Fee
    The fees charged under the Funding Proposal also would be similar 
to the ORF charged by the options

[[Page 44927]]

exchanges.\61\ The ORF is a per contract fee charged by an options 
exchange for certain options transactions to options members of the 
relevant exchange. The ORF is collected indirectly from exchange 
members through their clearing firms by the Options Clearing 
Corporation on behalf of the Exchange. Revenue generated from the ORF 
is designed to recover a material portion of an options exchange's 
regulatory costs related to the supervision and regulation of its 
members' options business, including performing routine surveillance, 
investigations, examinations and financial monitoring as well as 
policy, rulemaking, interpretive, and enforcement activities. Exchange 
members generally pass-through the ORF to their customers in the same 
manner that firms pass-through to their customers the fees charged by 
SROs to help the SROs meet their obligations under Section 31 of the 
Exchange Act.\62\ The CAT fees calculated under the Funding Proposal 
would be similar to the ORF in that they would be transaction-based 
fees intended to provide funding for regulatory costs.

Arca Fee Schedule.

2008), 73 FR 63744, 63745 (Oct. 27, 2008).
---------------------------------------------------------------------------

b. Fee Metric: Executed Equivalent Share Volume
    CAT LLC proposes to use the executed equivalent share volume of 
transactions in Eligible Securities as the means for allocating CAT 
costs among Participants and Industry Members. The use of executed 
equivalent share volume would replace the use of message traffic for 
allocating costs among Industry Members and the use of market share for 
allocating costs among Participants as set forth in the Original 
Funding Model. The use of executed equivalent share volume is a 
reasonable and equitable method for allocating costs for a variety of 
reasons, and CAT LLC believes it improves upon the use of message 
traffic.
    The proposed use of CAT-reported message traffic as set forth in 
the Original Funding Model raised a variety of issues for allocating 
CAT costs. First, based on a subsequent study of cost drivers for the 
CAT, it was determined that message traffic may be a factor in the CAT 
costs, but it is not the primary factor. CAT costs are dominated by 
technology costs, and the predominant technology costs are data 
processing (e.g., linker) and storage costs.\63\ The data processing 
and storage costs are related to the level of message traffic, but such 
costs also relate to other factors. The data processing and storage 
costs also are directly related to the complexity of the reporting 
requirements for the market activity. For example, in light of the 
complexity of market activity, the CAT's order reporting and linkage 
scenarios document for Industry Members is over 800 pages in length, 
addressing nearly 200 scenarios.\64\ The processing and storage of such 
a large number of complex reporting scenarios requires very complex 
algorithms, which, in turn, lead to significant data processing and 
storage costs. The data processing and storage costs also are driven by 
the stringent performance, timelines and operational requirements for 
processing CAT Data. For example, the CAT NMS Plan requires that CAT 
order events be processed within established timeframes to ensure data 
can be made available to Participants' regulatory staff and the SEC in 
a timely manner. Accordingly, a CAT Reporter's message traffic may be a 
factor, but not a primary factor, in terms of the costs of the CAT.
---------------------------------------------------------------------------

CAT LLC Webinar, CAT Costs (Sept. 21, 2021), <a href="https://www.catnmsplan.com/events/cat-costs-september-21-2021">https://www.catnmsplan.com/events/cat-costs-september-21-2021</a>.
    \64\ CAT Industry Member Reporting Scenarios, Version 4.16 (July 
31, 2025), <a href="https://www.catnmsplan.com/sites/default/files/2025-07/07.31.25_Industry_Member_Tech_Specs_Reporting_Scenarios_v4.16_CLEAN.pdf">https://www.catnmsplan.com/sites/default/files/2025-07/07.31.25_Industry_Member_Tech_Specs_Reporting_Scenarios_v4.16_CLEAN.pdf</a>.
---------------------------------------------------------------------------

    Second, in general, Industry Member revenue, including revenue 
derived from fees Industry Members charge their clients, is often 
driven by transactions. Because message traffic is separate from 
whether or not a transaction occurs, fees based on message traffic may 
not correlate with common revenue or fee models. As a result, CAT fees 
based on message traffic could impose an outsized adverse financial 
impact on certain Industry Members.
    Third, imposing CAT fees on each CAT Reporter based on its message 
traffic may have an adverse effect on competition, liquidity or other 
aspects of market structure, and may increase model complexity. For 
example, the number of messages for any given order, whether or not 
ultimately executed, could vary depending on how a given order is 
processed, leading to a lack of predictability on the applicable cost 
to process any given order or executions for broker-dealers or non-
broker-dealer customers.\65\ As one example, discussed in the context 
of the previously proposed funding models,\66\ market makers in 
Eligible Securities may have very high levels of message traffic due to 
their quoting obligations. Such high levels of message traffic may lead 
to outsized fees for market makers in comparison to their transaction 
activity, thereby placing an excessive financial burden on market 
makers. This, in turn, may lead to a decrease in the number of market 
makers, resulting in a decrease in liquidity and a reduction in market 
quality. To address this effect on market makers, CAT LLC proposed to 
discount the fees that market makers would need to pay. However, such a 
discount adds complexity to the message traffic approach, as the model 
must determine when a discount is necessary and how much the discount 
should be.
---------------------------------------------------------------------------

    \65\ The predictability of fees is discussed further below in 
Section A.9.u of this filing.
    \66\ See 2018 Fee Proposal Release.
---------------------------------------------------------------------------

    The use of executed equivalent share volume to allocate CAT costs 
addresses each of these concerns. The fees are not divorced from 
transactions, the traditional source of revenue for Industry Members; 
fees based on executed equivalent share volume would not adversely 
impact certain market participants to the detriment of the markets, and 
the model is simple to understand and implement. Moreover, in addition 
to these benefits, the executed equivalent share volume is related to, 
but not precisely linked to, the CAT Reporter's burden on the CAT. In 
light of the many inter-related cost drivers of the CAT (e.g., storage, 
message traffic, processing), determining the precise cost burden 
imposed by each individual CAT Reporter on the CAT is not feasible. 
Accordingly, CAT LLC has determined 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. This 
conclusion is consistent with the SEC's prior recognition of the use of 
transaction volume in setting regulatory fees. For example, in 
approving the FINRA TAF, the SEC recognized that transaction volume was 
closely enough connected to FINRA's regulatory responsibilities to 
satisfy the statutory standard in the Exchange Act.\67\

c. CAT Executing Brokers
i. Charging CAT Executing Brokers
    CAT LLC proposes to charge CAT fees to CAT Executing Brokers. CAT 
LLC believes that such an approach is consistent with the requirements 
of the Exchange Act for a variety of reasons, including the following 
reasons.
    First, the proposal to charge executing brokers is broadly 
supported by the

[[Page 44928]]

industry.\68\ For example, SIFMA has supported charging executing 
brokers, and continues to support charging executing brokers, rather 
than clearing brokers.\69\ In one of its comment letters on the 2022 
Funding Proposal, SIFMA stated that ``we support the Participants' 
decision to allocate CAT costs to executing brokers rather than 
clearing brokers.'' \70\ CAT LLC notes that there have been very few 
issues with the ability of CAT Executing Brokers to pay their invoices 
for CAT fees; approximately 99% of CAT fees are paid on time. CAT LLC 
understands that, under the Executed Share Model, many Industry Members 
have implemented processes to pass-through their CAT fees to upstream 
broker-dealers and customers.
---------------------------------------------------------------------------

    \68\ See Partial Amendment I at 74185; February 2023 Proposed 
Partial Amendment at 5.
    \69\ See Letter from Ellen Greene, Managing Director, Equities 
and Options Market Structure, SIFMA, to Vanessa Countryman, 
Secretary, SEC (Dec. 14, 2022) (``December 2022 SIFMA Letter'') at 
2; Letter from Ellen Greene, Managing Director, Equities and Options 
Market Structure, SIFMA, to Vanessa Countryman, Secretary, SEC (Oct. 
7, 2022) at 4-5.
    \70\ Letter from Ellen Greene, Managing Director, Equities and 
Options Market Structure, and Joseph Corcoran, Managing Director, 
Associate General Counsel, SIFMA, to Vanessa Countryman, Secretary, 
SEC (Jan. 12, 2023) at 7. See also December 2022 SIFMA Letter at 2 
(``[W]e support changing the payment obligation to executing 
brokers.'').
---------------------------------------------------------------------------

    Second, the proposal to rely on executing brokers, rather than 
clearing brokers, was proposed in direct response to comments raised by 
SIFMA and other commenters on the 2022 Funding Proposal regarding the 
cost burden that clearing firms may experience if clearing brokers were 
charged CAT fees.\71\ As noted by commenters, imposing the fee payment 
obligation on clearing brokers, rather than on executing brokers more 
generally, potentially may impose a significant financial burden on 
clearing firms if the fees imposed on clearing firms are not passed 
through to their clients.
---------------------------------------------------------------------------

    \71\ See Partial Amendment I at 74185; February 2023 Proposed 
Partial Amendment at 5.
---------------------------------------------------------------------------

    Third, charging the CEBBs and CEBSs would reflect the executing 
role the CEBB and CEBS have in each transaction. Such a fee model is 
currently used and well-known in the securities markets. For example, 
SRO members regularly pay transaction-based fees. As a result, the CAT 
fees could be paid by Industry Members without requiring significant 
and potentially costly changes.
    Fourth, charging CEBBs and CEBSs is in line with the use of 
transaction reports from the exchanges and FINRA's equity trading 
reporting facilities for calculating the CAT fees. The CEBBs and CEBSs 
are identified on the transaction reports, thereby streamlining the CAT 
collection process.
    Fifth, CAT LLC does not believe that the proposal would burden CAT 
Executing Brokers. The CEBBs and CEBSs could determine, but would not 
be required, to pass their CAT fees through to their clients (both non-
broker-dealer customers and upstream broker-dealers), who, in turn, 
could pass their CAT fees to their clients, until the fee is imposed on 
the ultimate participant in the transaction. With such a pass-through, 
the CEBBs and CEBSs would not ultimately incur the cost of all CAT fees 
related to their transactions. It is common practice in the industry 
for broker-dealers to pass transaction-based fees through to their 
clients, and CAT fees would introduce no unique issues for passing the 
CAT fee on to clients. Indeed, CAT LLC understands that, under the 
Executed Share Model, many Industry Members have implemented processes 
to pass-through their CAT fees to upstream broker-dealers and 
customers. Moreover, those CAT Executing Brokers that do not directly 
pass-through their CAT fees may account for and recover such fees as 
part of their overall business costs when considering and establishing 
other revenue-generating sources.
    Finally, the proposal to charge CAT Executing Brokers CAT fees as 
set forth in the Funding Proposal only addresses the party responsible 
for the payment of the CAT fee. As an administrative matter regarding 
the method of payment, each CAT Executing Broker may seek to enter into 
a bilateral arrangement with its clearing broker for the clearing 
broker to collect and pass-through the CAT fees as it does in other 
contexts.
ii. Effect on Net Capital of CAT Executing Brokers
    CAT fees do not raise new or different issues for CAT Executing 
Brokers with respect to net capital requirements than other 
transaction-based fees charged to executing brokers. CAT fees will be 
billed on a monthly basis, and Section 11.4 of the CAT NMS Plan states 
that ``Participants shall require each Industry Member to pay all 
applicable fees authorized under this Article XI within thirty (30) 
days after receipt of an invoice or other notice indicating payment is 
due (unless a longer payment period is otherwise indicated).'' With 
respect to net capital requirements, CAT Executing Brokers may 
determine whether to establish arrangements with their brokerage 
clients to account for costs incurred by the CAT Executing Broker on 
the client's behalf, including setting the terms under which they must 
be repaid by their broker-dealer clients such that receivables need not 
extend beyond 30 days.
d. Cost Allocation
i. One-Third/One-Third/One-Third Allocation of Prospective CAT Costs 
Between CEBS, CEBB and Participant
    When calculating the CAT Fees related to Prospective CAT Costs 
under the Funding Proposal, CAT LLC proposes to allocate one-third of 
Prospective CAT Costs to Participants, one-third of Prospective CAT 
Costs to CEBSs and one-third of Prospective CAT Costs to CEBBs. CAT LLC 
believes that this proposed allocation satisfies the requirements of 
the Exchange Act and Rule 608 of Regulation NMS under the Exchange Act.
    The proposed \1/3\, \1/3\, \1/3\ allocation of Prospective CAT 
Costs recognizes the three primary roles in each transaction: the 
buyer, the seller and the market regulator, and assigns an equal one-
third share of the fee per transaction to each of these three roles. 
The Exchange Act itself recognizes the importance of these three roles 
in a transaction by imposing registration and other regulatory 
obligations on the broker-dealers and regulator involved in a 
transaction. This allocation is similar to the approach taken with the 
FINRA TAF, ORF and Section 31 sales value fees, and also recognizes the 
role of the market regulator and the buyer in the transaction as well 
as the seller.\72\
---------------------------------------------------------------------------

    \72\ As discussed below in Section A.9.e, Proposed Section 
11.3(e) of the CAT NMS Plan would maintain the Participants' one-
third contribution to CAT costs.
---------------------------------------------------------------------------

    Furthermore, the allocation of two-thirds of the CAT costs to 
Industry Members and only one-third to Participants recognizes that a 
substantial portion of CAT costs originates from Industry Members. CAT 
costs are dominated by technology costs, and the predominant technology 
costs are data processing (e.g., linker) and storage costs. The data 
processing and storage costs are related to message traffic and the 
complexity of the reporting requirements for CAT, which, in turn, are 
determined by market activity. Industry Members are responsible for 
originating trading activity that necessitates message traffic to the 
CAT, and the complexity of Industry Members' chosen business models 
contributes substantially to the costs of the CAT.

[[Page 44929]]

    One of the factors driving CAT costs is the complexity of the 
Industry Members' CAT reporting requirements, which are driven by the 
inherent complexity of Industry Members' chosen business models. For 
example, in light of the complexity of market activity, the CAT's 
reporting scenarios document for Industry Members is over 800 pages in 
length, addressing almost 200 scenarios, including, for example, 
scenarios related to representative orders, internal routing, order 
modification, order cancellation, ATS scenarios, OTC scenarios, foreign 
scenarios, child orders, proprietary orders, fractional shares, stop 
and conditional orders, RFQs, floor activity and more.\73\ The 
processing and storage of such a large number of complex reporting 
scenarios requires very complex algorithms, which, in turn, lead to 
significant data processing and storage costs. In contrast, the 
Participants do not originate market activity or orders or otherwise 
bring this level of complexity to the markets. As a result, the 
technical specifications for the Participants are far less complex than 
for Industry Members. For example, the technical specifications for 
Participants have 13 reporting events for stock exchanges compared to 
39 equity reporting events in the technical specifications for Industry 
Members, and the technical specifications for Participants have 28 
reporting events for options exchanges compared to 60 reporting options 
events in the technical specifications for Industry Members.\74\ Since 
the complexity of Industry Members' chosen business models contributes 
substantially to the costs of the CAT, it is reasonable and equitable 
to require that Industry Members pay a substantial portion of those 
costs.

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

    Participant activity does not impact CAT costs in the same way that 
Industry Member activity impacts CAT costs. The analysis regarding the 
complexity of Industry Member activity is based on the effects of the 
business models on the costs of the CAT, not on the complexity of the 
market generally. The complexity of Industry Member activity adds 
significantly to the cost of the CAT in a way that Participant activity 
does not.
    Moreover, allocating a greater percentage of the CAT costs to 
Participants would raise fairness issues in light of the greater 
financial resources of Industry Members. There are only 27 Participants 
and approximately 1,000 Industry Members.\75\ Moreover, based upon a 
2021 analysis of available CAT Reporter revenue, Participants only 
represented approximately 4% of the total CAT Reporter revenue while 
Industry Members represented 96% of the total CAT Reporter revenue.\76\ 
In addition, various individual Industry Members have revenue in excess 
of some or all of the Participants. Accordingly, CAT LLC determined 
that allocating a higher percentage of the total CAT costs to the 
Participants was not a fair and equitable approach.
---------------------------------------------------------------------------

    \75\ Approximately 1,034 unique CAT Reporters sent transaction 
data to the CAT in August 2025.
    \76\ See Securities Exchange Act Rel. No. 91555 (Apr. 14, 2021), 
86 FR 21050, 20155 (Apr. 21, 2021) (``2021 Fee Proposal Release''). 
Industry Member revenue was calculated based on the total revenue 
reported in the Industry Member's FOCUS reports. Participant revenue 
was calculated based on revenue information provided in Form 1 
amendments and/or publicly reported figures. Participants are not 
required to file uniform FOCUS-type reports regarding revenue like 
Industry Members. Accordingly, the revenue calculation for 
Participants is not as straightforward as for Industry Members.
---------------------------------------------------------------------------

    Finally, CAT LLC analyzed a variety of alternative allocations of 
CAT costs and continues to support the proposed one-third, one-third, 
one-third allocation as consistent with the requirements of the 
Exchange Act and the CAT NMS Plan. Alternative allocations considered 
by CAT LLC are discussed in detail below in Section A.10 of this 
filing.
ii. \1/3\, \1/3\ Allocation for Historical CAT Assessment
    Under the Funding Proposal, the CEBS and the CEBB would each pay 
one-third of the fee obligation for each transaction related to 
Historical CAT Costs. Because the Participants have already paid for 
Past CAT Costs via loans to CAT LLC, the Participants would not be 
required to pay any Historical CAT Assessment. As stated in Proposed 
Section 11.3(b)(ii) of the CAT NMS Plan, ``[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 ``Historical CAT 
Assessments are designed to recover two-thirds of the Historical CAT 
Costs.'' Like with the allocation of Prospective CAT Costs discussed 
above, CAT LLC believes that the proposed allocation of the Historical 
CAT Costs is consistent with the requirements of the Exchange Act and 
the CAT NMS Plan.
iii. Internal Cost of Compliance by Industry Members
    CAT LLC does not propose to take into consideration the internal 
costs incurred by Industry Members in complying with CAT requirements 
in determining how to allocate costs between Industry Members and 
Participants. There is no precedent for regulatory fees to be 
determined based on the cost of compliance of the regulated entity. 
Regulatory fees are intended to cover the regulatory costs of the 
entity providing the regulation. In the case of the CAT, the Funding 
Proposal is intended to charge fees to pay for the direct costs of the 
CAT, not for ancillary compliance costs of Industry Members.\77\ 
Moreover, as a practical matter, accurately determining an Industry 
Member's compliance costs, without recordkeeping requirements and 
appropriate standards to determine expenses accurately, would be 
infeasible.
---------------------------------------------------------------------------

    \77\ See CAT NMS Plan Approval Order at 84795, n.1749 (``The 
Participants stated that the funding model provides a framework for 
the recovery of the costs to create, develop and maintain the CAT, 
and is not meant to address the cost of compliance for Industry 
Members and Participants with the reporting requirements of Rule 
613.'').
---------------------------------------------------------------------------

    Likewise, the substantial internal compliance costs of the 
Participants are not taken into consideration in the Funding Proposal. 
Each Participant incurs its own internal costs to comply with the 
requirements of the CAT NMS Plan, including, among other things, 
updating its systems for CAT reporting. Additionally, Participants have 
expended countless internal hours on the creation, implementation and 
operation of the CAT. These costs are not included in the cost 
allocation under the Funding Proposal.
iv. Alternative Approach Based on Individualized CAT Reporter Cost to 
CAT
    CAT LLC has determined not to propose a funding approach for the 
CAT in which a CAT Reporter's fees would be based on each CAT 
Reporter's exact cost burden on the CAT. In light of the many inter-
related cost drivers of the CAT (e.g., storage, message traffic, 
processing), determining the precise cost burden imposed by each 
individual CAT Reporter on the CAT is not feasible. Moreover, trading 
activity

[[Page 44930]]

provides a reasonable proxy for cost burden on the CAT, and therefore 
is an appropriate metric for allocating CAT costs among CAT Reporters. 
CAT LLC emphasizes that the Exchange Act requires CAT fees to be fair, 
reasonable and equitably allocated, and CAT LLC believes that the use 
of executed equivalent share volume satisfies these requirements. The 
Exchange Act does not require each CAT Reporter's fees to be a proxy 
for that CAT Reporter's cost burden on the CAT, let alone an exact 
proxy.
A. Difficulty in Determining Individual CAT Reporter Costs Due to 
Inter-Related Cost Drivers
    CAT LLC has analyzed the cost drivers for the CAT, and has 
concluded that determining the precise cost burden imposed by each 
individual CAT Reporter on the CAT is not feasible. The computation of 
a specific CAT Reporter's burden on the CAT is complicated by the many 
inter-related factors that contribute to CAT costs, including message 
traffic, data processing, storage, the complexity of reporting 
requirements, reporting timelines, infrastructure, connectivity and 
more. The use of executed equivalent share volume as the metric for the 
funding model is an improvement over the message traffic model. CAT LLC 
analyzed the cost drivers of CAT and determined that, although message 
traffic is one factor in CAT costs, it is not the primary factor. CAT 
costs are dominated by technology costs, and the predominant technology 
costs are data processing (e.g., linker) and storage costs. Compute 
costs represent more than half of all technology costs. While such 
costs are related in part to message traffic, they are driven by the 
stringent performance timelines, data complexity and operational 
requirements in the CAT NMS Plan. The Plan requires that order events 
be processed, corrected, and made available to regulatory users within 
established timeframes, including a four-hour window for initial 
linkage processing. For this reason, among other issues with the 
message traffic model and other considerations discussed herein, CAT 
LLC determined to shift its focus to the new metric of executed 
equivalent share volume from the message traffic and market share 
metrics set forth in the CAT NMS Plan as approved.
B. Trading Activity as Reasonable Proxy for Cost Burden
    CAT LLC determined 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. CAT LLC analyzed 
reasonable metrics for determining CAT fees, and determined that, 
although executed equivalent share volume is not an exact proxy for the 
cost burden (nor need it be), trading activity provides a reasonable 
proxy for cost burden on the CAT. Increased trading activity impacts 
message traffic, data processing, storage and other factors, and thus 
necessarily correlates with increased cost burden on the CAT. Moreover, 
Industry Member activity in the market generally is engaged in for the 
purpose of effecting transactions, and, as a result, it is common for 
Participants to use transaction-based fees. Therefore, executed share 
volume is an appropriate metric for allocating CAT costs among CAT 
Reporters.
    This conclusion is consistent with the SEC's prior recognition of 
the use of transaction volume in setting regulatory fees. For example, 
in approving FINRA's TAF, the SEC recognized that transaction volume 
was closely enough connected to FINRA's broad regulatory 
responsibilities to satisfy the statutory standard in the Exchange 
Act.\78\ FINRA proposed a transaction-based TAF to fund its member 
regulatory activities in a variety of areas such as ``sales practices, 
routine examinations, financial and operational reviews, new member 
applications, enforcement * * * . . . wherever such member activity 
occurs.'' \79\ The SEC noted that ``[a]ssessing fees in relation to 
transactions correlates to heightened NASD responsibilities regarding 
firms that engage in the trading,'' but the fees were not an exact 
proxy for the costs of such regulatory responsibilities.\80\ The SEC 
noted this lack of a precise correlation:
---------------------------------------------------------------------------

    \78\ TAF Release at 34023.
    \79\ Id.
    \80\ Id.
---------------------------------------------------------------------------

    In most cases, the NASD has direct responsibility to oversee the 
firm's dealing with the public in effecting the transactions; the NASD 
may also have responsibility to oversee the impact of the trading on 
the firm's financial condition. In most cases, where responsibility for 
certain member activities has been allocated to other SROs, the NASD 
retains responsibility for other member functions.\81\
---------------------------------------------------------------------------

    \81\ Id.
---------------------------------------------------------------------------

    Nevertheless, the SEC concluded that ``while trading activity is 
not wholly correlated to the full range of NASD responsibility for 
members in all instances, the Commission believes that they are closely 
enough connected to satisfy the statutory standard.'' \82\ CAT LLC 
believes that this same logic is applicable to the Funding Proposal.
---------------------------------------------------------------------------

    \82\ Id. at 34024.
---------------------------------------------------------------------------

v. Alternative Approach: 50-50 Allocation Between Industry Members and 
Participant Exchanges
    CAT LLC has considered and rejected allocating 50% of CAT costs to 
the Participants and 50% to Industry Members under the Funding 
Proposal. Although a 50-50 allocation between Industry Members and 
Participants would provide a mathematically equal split between two 
groups, it would not provide an equitable allocation between and among 
Industry Members and Participants. Such an allocation raises fairness 
issues as Industry Members have far greater financial resources than 
the Participants, and the complexity of Industry Members' chosen 
business models contributes substantially to the costs of the CAT.
e. Fee Pass-Throughs
i. Fee Pass-Throughs by Participants
    As discussed above, the Eleventh Circuit vacated the SEC's order 
approving the Executed Share Model, noting, in part, that the 
Commission allowed ``self-regulatory organizations to pass through 100% 
of their fees to broker-dealers--without considering the effects of 
that choice.'' \83\ CAT LLC proposes to add Section 11.3(e) to the CAT 
NMS Plan regarding Participant pass-through fees to address the Court's 
order. As set forth in Proposed Section 11.3(e) of the CAT NMS Plan, 
``Each Participant agrees not to file with the SEC a proposed rule 
change pursuant to Section 19(b) 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).'' 
Accordingly, Participants would agree not to file any fee filing with 
the Commission to assess on its members CAT fees charged to such 
Participant. This provision is intended to maintain the one-third 
allocation of CAT costs as a Participant obligation, and to be 
responsive to the Eleventh Circuit's opinion with respect to the 
potential for 100% pass-through costs.

Comm'n, No. 23-13396, 2025 WL 2092054 (11th Cir. July 25, 2025).
---------------------------------------------------------------------------

ii. Fee Pass-Throughs by CAT Executing Brokers
    CAT LLC acknowledges that CAT Executing Brokers may choose to pass 
their CAT fees through to their clients, who, in turn, may pass their 
CAT fees

[[Page 44931]]

through to their clients, until the fees are imposed on the account 
that executed the transaction, in lieu of paying CAT fees through other 
means. The Funding Proposal does not limit or prohibit such pass-
throughs, nor does CAT LLC take a position on whether Industry Members 
should pass CAT fees on to their clients; however, CAT LLC understands 
that many Industry Members have implemented processes to pass-through 
their CAT fees to upstream broker-dealers and customers.
    In adopting the CAT NMS Plan, the Commission specifically 
contemplated and accepted that ``broker-dealers may seek to pass on to 
investors their costs to build and maintain the CAT, which may include 
their own costs and any costs passed on to them by Participants,'' 
noting that the ``extent to which these costs are passed on to 
investors depends on the materiality of the costs and the ease with 
which investors can substitute away from any given broker-dealer.'' 
\84\ Moreover, CAT LLC notes that the use of pass-through fees by 
broker-dealers is a commonly accepted practice that has been approved 
by the SEC in the securities markets in some cases. For example, the 
SEC has recognized the common practice of broker-dealers passing 
through Section 31-related fees to their customers.\85\ The pass-
through concept also is applied in the context of other SRO regulatory 
fees applicable to the SROs' members. For example, ``it is regular 
practice among some clearing and trading firms to `pass through' the 
TAF to the underlying firm executing the trade. Further, FINRA 
understands that the executing firms commonly pass the TAF directly on 
to their customers. Typically, TAF fees are reflected on the 
confirmation statement received by customers.'' \86\ Similarly, the 
pass-through process is used for ORFs as well. ORFs are collected 
indirectly from members through their clearing firms by OCC on behalf 
of the respective options exchange. As noted in rule filings related to 
ORFs, ``[t]he Exchange expects that [members] will pass through the ORF 
to their customers in the same manner that firms pass-through to their 
customers the fees charged by Self-Regulatory Organizations (`SROs') to 
help the SROs meet their obligations under Section 31 of the Exchange 
Act.'' \87\

    CAT LLC understands that it has been common practice for Industry 
Members to pass-through their CAT fees directly to their clients to 
date. Indeed, commenters on prior CAT funding proposals have advocated 
for CAT fees to be structured in such a way as to easily pass-through 
such fees to their clients. For example, one commenter commented in 
favor of a model similar to the Section 31 fees in which the fee could 
be passed through to ultimate customers.\88\ Similarly, another 
commenter noted the benefits of a model that allows fees to be passed 
through to customers, arguing that ``[i]t would also provide 
transparency into the fees which seek to recoup costs and a vehicle to 
pass-thru fees to the ultimate beneficiary of each trade.'' \89\

    CAT LLC does not believe that the Funding Proposal raises issues 
with regard to Industry Members that do not have customers, and 
therefore cannot directly pass their CAT fees on and must pay for their 
CAT fees in other ways. Such Industry Members should not be evaluated 
differently based upon the inability to recoup CAT fees by directly 
assessing them to counterparties that are not customers. First, as 
noted above, the Funding Proposal does not set forth any requirement 
regarding whether or not an Industry Member may or may not pass-through 
its CAT fees to its customers; such pass-throughs are outside of the 
Funding Proposal. Second, each CAT Executing Broker will need to 
determine for itself how it will obtain the funds to pay for its CAT 
fees. Industry Members that do not have customers have revenue-
generating activity other than direct pass-through of fees to fund the 
CAT fees (e.g., market making activity). As a former member of the 
Advisory Committee for the CAT and the former Chief Economist of the 
Commission explained, even if CAT fees are not passed through directly, 
such costs would ultimately be passed on through a change in services 
or other costs.\90\

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

f. FINRA Fee
    Under the Funding Proposal, for each transaction in Eligible 
Securities based on CAT Data, the CEBS, the CEBB and the applicable 
Participant for the transaction each would pay a CAT Fee calculated by 
multiplying the number of executed equivalent shares in the transaction 
and the applicable Fee Rate and dividing the product by three. The 
applicable Participant for the transaction would be the national 
securities exchange on which the transaction was executed, or FINRA for 
each transaction executed otherwise than on an exchange. CAT LLC 
believes that the proposed CAT fees for FINRA are consistent with the 
Exchange Act and the CAT NMS Plan. CAT LLC does not believe that the 
assessment of a CAT fee on FINRA in the same manner as other 
Participants would result in a burden on competition for FINRA or for 
Industry Members engaging in activity otherwise than on an exchange.
    The Funding Proposal is designed to be neutral as to the manner of 
execution and place of execution. The CAT fees would be the same 
regardless of whether the transaction is executed on an exchange or in 
the over-the-counter market. All Participants are self-regulatory 
organizations that have the same regulatory obligations under the 
Exchange Act, regardless of whether they operate as a for-profit or 
not-for-profit entity. Their usage of CAT Data, either directly or 
indirectly through regulatory services agreements, would be for the 
same regulatory purposes in accordance with those obligations. By 
treating each Participant the same, the CAT fees would not become a 
competitive issue by and among the Participants, or a competitive issue 
between on exchange and off exchange trading.
    In addition, the size of FINRA's fee is calculated based on the 
activity in the over-the-counter market, which is substantial. For 
example, the executed equivalent share volume for over-the-counter 
trades in Eligible Securities in

[[Page 44932]]

June 2025 was 377,983,597,154.08 out of a total volume of 
952,977,614,616.08 executed equivalent shares for trades in Eligible 
Securities. Accordingly, approximately 40% of the executed equivalent 
share volume in Eligible Securities took place in the over-the-counter 
market.
    Furthermore, FINRA and the exchanges should not be evaluated 
differently based upon the potential for a particular Participant to 
recoup its fees through revenue-generating activity other than fees 
imposed on its members. Each Participant will need to determine for 
itself how it will obtain the funds to pay for its CAT fees. FINRA, 
just like the exchange Participants, has revenue sources other than 
membership fees. For example, FINRA generates significant revenues via 
regulatory services agreements with the exchanges, among other 
sources.\91\ These sources, too, may be used to pay CAT fees, and, if 
they are used, it would not lead to an increase in fees for Industry 
Members, but rather the exchange Participants. Any review of how the 
Participants obtain their funds to pay CAT fees is beyond the scope of 
the CAT fee filing.
---------------------------------------------------------------------------

    \91\ See 2024 FINRA Annual Financial Report at 43.
---------------------------------------------------------------------------

    Finally, CAT LLC does not believe that FINRA should not be treated 
as a market center for CAT funding purposes merely because FINRA is not 
treated as a market center for governance purposes under the National 
Market System Plan Regarding Consolidated Equity Market Data (``CT 
Plan''). Although the CT Plan and the CAT Plan are both national market 
system plans, their purpose and implementation are different. The CAT 
NMS Plan, as approved by the Commission, explicitly contemplates 
charging fees to all Participants, including FINRA. For example, 
Section 11.1(b) of the CAT NMS Plan states that ``[s]ubject to Section 
11.2, the Operating Committee shall have discretion to establish 
funding for the Company, including: (i) establishing fees that the 
Participants shall pay.'' \92\ In addition, the purpose of the CAT is 
solely for regulatory purposes; it provides a regulatory system to 
facilitate the performance of the self-regulatory obligations of all 
the Participants, including the exchanges and FINRA. In contrast, the 
CT Plan governs the public dissemination of real-time consolidated 
equity market data for NMS stocks.
---------------------------------------------------------------------------

    \92\ See also Sections 11.2 and 11.3 of the CAT NMS Plan.
---------------------------------------------------------------------------

g. Impact on Options Versus Equities
    CAT LLC believes that the Funding Proposal provides for a fair, 
reasonable and equitable treatment of the equities and options markets. 
CAT LLC does not believe that the Funding Proposal would burden 
inappropriately efficiency, competition or capital formation in how it 
treats equities and options. As a preliminary matter, unlike other 
previously proposed fee models,\93\ the Funding Proposal does not 
allocate costs between the equities and options markets; instead, the 
fee attributable to a transaction in an equity or option security 
depends on equivalent executed share volume. In addition, the use of 
equivalent executed share volume is designed to normalize options and 
equities in the calculation of fees, and to recognize and address the 
different trading characteristics of different types of securities. 
Recognizing that Listed Options trade in contracts rather than shares, 
the Funding Proposal would count executed equivalent share volume 
differently for Listed Options. Specifically, each executed contract 
for a transaction in Listed Options would be counted based on the 
multiplier applicable to the specific Listed Option contract in the 
relevant transaction (e.g., 100 executed equivalent shares or such 
other applicable equivalency).
---------------------------------------------------------------------------

    \93\ See, e.g., 2018 Fee Proposal Release at 1400.
---------------------------------------------------------------------------

h. Sell-Side and Buy-Side
    CAT LLC proposes to charge both the buy-side and sell-side of a 
transaction in Eligible Securities a CAT fee. The proposal to charge 
both the buy-side and the sell-side of a transaction is consistent with 
other types of fees charged to both the buyer and the seller that are 
common in the industry. As such, CAT LLC believes that the proposal 
would comply with the requirements of the Exchange Act. For example, 
the ORF, a fee common to the options exchanges, is one example of a 
regulatory fee charged to both the buy-side and sell-side of the 
transaction. For example, the MIAX fee schedule lists the options 
regulatory fee as applying ``per executed contract side.'' \94\ 
Similarly, under its pricing schedule, Nasdaq PHLX charges an options 
regulatory fee ``per contract side.'' \95\ As set forth in its fee 
schedule, CBOE EDGX also charges an options regulatory fee to each side 
of the contract.\96\ In addition, the industry is familiar with 
transaction-based fees charged to both the buyer and the seller by the 
exchanges and FINRA.\97\

i. Fee Rate Changes Twice per Year for CAT Fees Related to Prospective 
CAT Costs
    CAT LLC proposes to require the calculation of the Fee Rate for CAT 
Fees related to Prospective CAT Costs twice a year. CAT LLC believes 
that the proposal to adjust the Fee Rate twice a year, once at the 
beginning of the year and once during the year, appropriately balances 
the need to coordinate the Fee Rate with potential changes in the costs 
and projections with the cost and effort to the industry related to 
more frequent fee changes.
    CAT LLC believes its proposal is in keeping with views expressed by 
the industry in other contexts regarding the appropriate frequency of 
regulatory rate changes. For example, in the ORF context, the industry 
requested that rate changes be limited to twice per year. SIFMA stated 
in a comment letter on one of the ORF fee proposals that ``[r]ates 
should only be changed two times per year to reduce operational 
complexity and reduce risk.'' \98\ The exchanges with ORF fees noted 
that the possibility for fee rate changes only twice per year would 
also ``better enable [their members] to properly account for ORF 
charges among their customers.'' \99\

j. Plan Amendment Process for Fee Rate Changes
    Under the Funding Proposal, once any Fee Rate has been established 
by a majority vote of the Operating Committee in accordance with the 
Funding Proposal set forth in the CAT NMS Plan,\100\ each Participant 
would be required to pay the applicable CAT Fee calculated in 
accordance with the requirements set forth in the CAT NMS Plan (subject 
to the requirement for the Industry Member CAT Fee to be in effect). 
CAT LLC does not plan to submit an amendment to the CAT NMS Plan each 
time that the Fee Rate for the CAT Fee is established or adjusted 
because of the length of time and burden required to amend the CAT NMS 
Plan for each adjustment to the Fee Rate. Moreover, CAT LLC believes 
that it is unnecessary to file a new separate amendment for the 
Participant CAT Fees each time a new Fee Rate is

[[Page 44933]]

approved because the CAT NMS Plan would set forth in detail the manner 
in which the CAT fees are established and the inputs for calculating 
the specific CAT Fees would be published on the CAT website and 
included in the Participant fee filings under Section 19(b) of the 
Exchange Act for Industry Member CAT fees. Therefore, the amendments to 
the Plan for a fee rate change would be redundant and impractical in 
terms of timing.
---------------------------------------------------------------------------

    \100\ Participants would be required to pay the CAT Fee once the 
CAT Fee is in effect with regard to Industry Members in accordance 
with Section 19(b) of the Exchange Act.
---------------------------------------------------------------------------

    CAT LLC proposes to amend the CAT NMS Plan to describe in detail 
how CAT Fees would be calculated, including the formula for the 
calculation and the methods for determining the inputs for the 
calculation (i.e., the budget, projected executed equivalent share 
volume, executed equivalent shares per transaction). As such, the 
Participants would be required to calculate the Fee Rate and the 
related CAT Fees using the proposed formula; this process would be 
mandatory, including the mid-year Fee Rate change. Moreover, the 
budgetary and projection inputs to the calculation would be public, 
including in public fee filings pursuant to Section 19(b) of the 
Exchange. Accordingly, CAT LLC does not believe that a Plan amendment 
would be necessary each time a new Fee Rate is calculated in accordance 
with the Plan.
    The CAT NMS Plan would require each Participant to pay the proposed 
CAT Fees determined in accordance with the Funding Proposal. Proposed 
Section 11.3(a)(ii)(A) sets forth the requirement for Participants to 
pay the CAT fees. It states that ``[e]ach 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,'' and that ``[e]ach 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.'' It further states 
that ``[t]he 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 reasonably 
determined pursuant to paragraph (a)(i) of this Section 11.3.'' In 
addition, proposed 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 the prior month.''
    The Participants would be required to follow the requirements set 
forth in the CAT NMS Plan for establishing and calculating CAT Fees and 
requiring the payment of the CAT Fees as both a regulatory and 
contractual matter. Rule 613(h)(1) of Regulation NMS under the Exchange 
Act states that ``[e]ach national securities exchange and national 
securities association shall comply with the provisions of the national 
market system plan approved by the Commission,'' that is, the CAT NMS 
Plan. Rule 613(h)(2) of Regulation NMS under the Exchange Act states 
that ``[a]ny failure by a national securities exchange or national 
securities association to comply with the provisions of the national 
market system plan approved by the Commission shall be considered a 
violation of this section.'' Similarly, Rule 608(c) of Regulation NMS 
under the Exchange Act states that ``[e]ach self-regulatory 
organization shall comply with the terms of any effective national 
market system plan of which it is a sponsor or a participant.'' Section 
3.11 of the CAT NMS Plan reiterates this requirement, stating that 
``[e]ach Participant shall comply with . . . the provisions of SEC Rule 
613 and of this Agreement, as applicable, to the Participant.'' In 
addition, each Participant is a signatory to the CAT NMS Plan as a 
member of the limited liability company. Accordingly, a failure to 
comply with the requirements of the CAT NMS Plan related to the CAT 
fees would be a violation of the regulatory obligation to comply with 
the CAT NMS Plan and a breach of contractual requirements of the CAT 
NMS Plan.
k. Executed Equivalent Shares for NMS Stocks, Listed Options and OTC 
Equity Securities
    The Funding Proposal uses the concept of executed equivalent shares 
as the metric for calculating CAT fees for transactions in NMS Stocks, 
Listed Options and OTC Equity Securities, each of which have different 
trading characteristics. Under the Funding Proposal, each executed 
share for a transaction in NMS Stocks would be counted as one executed 
equivalent share, 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 each 
executed share for a transaction in OTC Equity Securities would be 
counted as 0.01 executed equivalent shares. CAT LLC believes that the 
proposed counting methods for each category of security are 
appropriate, as discussed in detail above in Section A.3.b.ii of this 
filing.
l. Cost Transparency
i. Cost Transparency and Level of Detail of CAT Costs
    CAT LLC provides substantial cost transparency for Past CAT Costs 
and Prospective CAT Costs, including transparency above and beyond what 
is required under the CAT NMS Plan, and more than other national market 
system plans. Such transparency includes cost descriptions in the fee 
filings made pursuant to Section 19(b) of the Exchange Act and Rule 
19b-4(f)(2) thereunder, as well as the public availability of CAT 
financial and budget information.
    CAT LLC proposes to require substantial transparency for CAT costs 
in the fee filings to be made pursuant to Section 19(b) of the Exchange 
Act. For example, Proposed Section 11.3(a)(iii)(B) of the CAT NMS Plan 
would require such filings for CAT Fees to include, among other things, 
the budget for the upcoming year (or remainder of the year, as 
applicable), including a brief description of each line item in the 
budget, including (1) 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, a reserve and/or such other categories as reasonably 
determined by the Operating Committee to be included in the budget and 
the reason for changes in each such line item from the prior CAT Fee 
filing; and a discussion of how the budget is reconciled to the 
collected fees. Similarly, Proposed Section 11.3(b)(iii)(B)(II) of the 
CAT NMS Plan would require such filings for Historical CAT Assessments 
to include, among other things, a brief description of the amount and 
type of Historical CAT Costs, including (1) 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.
    CAT LLC provides substantial additional financial information 
regarding the operation of the CAT as required by the CAT NMS Plan. For 
example, CAT LLC currently makes detailed financial information about 
the CAT publicly available. Section 9.2(a) of the CAT NMS Plan requires 
CAT LLC to maintain a system of accounting

[[Page 44934]]

established and administered in accordance with GAAP and requires ``all 
financial statements or information that may be supplied to the 
Participants shall be prepared in accordance with GAAP (except that 
unaudited statements shall be subject to year-end adjustments and need 
not include footnotes).'' Section 9.2(a) of the CAT NMS Plan also 
requires the Company to prepare and provide to each Participant ``as 
soon as practicable after the end of each Fiscal Year, a balance sheet, 
income statement, statement of cash flows and statement of changes in 
equity for, or as of the end of, such year, audited by an independent 
public accounting firm.'' The CAT NMS Plan requires that this audited 
balance sheet, income statement, statement of cash flows and statement 
of changes in equity be made publicly available. Among other things, 
these financial statements provide operating expenses, including 
technology, legal, consulting, insurance, professional and 
administration and public relations costs. CAT LLC also maintains a 
dedicated web page on the CAT NMS Plan website that consolidates its 
annual financial statements in a public and readily accessible 
place.\101\ The Company's annual financial statements from inception in 
2017 through 2023 are currently available on the CAT website.
---------------------------------------------------------------------------

    \101\ See CAT Audited Financial Statements, <a href="https://www.catnmsplan.com/audited-financialstatements">https://www.catnmsplan.com/audited-financialstatements</a>.
---------------------------------------------------------------------------

    In addition to providing financial information required under the 
CAT NMS Plan and otherwise, CAT LLC also has voluntarily determined to 
provide more financial transparency to the public regarding its costs. 
For example, CAT LLC publicly provides its annual operating budget as 
well as periodically provides updates to the budget that occur during 
the year. CAT LLC includes such budget information on a dedicated web 
page on the CAT NMS Plan website to make it readily accessible to the 
public, like the CAT financial statements. CAT LLC also has held 
webinars providing additional detail about CAT costs and about 
potential alternative funding models for the CAT, and commenters 
submitted questions and comments on the webinars.\102\

ii. Composition and Transparency of Past CAT Costs
    CAT LLC also provides detailed disclosures regarding Past CAT 
Costs. The Historical Fee Rate for each Historical CAT Assessment would 
be calculated based on actual past costs incurred by the CAT (except 
any costs that CAT LLC has determined to exclude from the calculation), 
rather than budgeted costs. The audited financial statements for CAT 
LLC and its predecessor CAT NMS, LLC, which describe the actual costs 
for CAT LLC, are available on the CAT website.\103\ In addition, the 
Historical CAT Costs for prior to 2022 are described in detail in the 
Participants' rule filings for Historical CAT Assessment 1.\104\ The
