July 3, 2025.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(the ``Act'' or the ``Exchange Act''),\1\ and Rule 19b-4 thereunder,\2\ 
notice is hereby given that on June 27, 2025, Cboe Exchange, Inc. (the 
``Exchange'' or ``Cboe Options'') filed with the Securities and

I. Self-Regulatory Organization's Statement of the Terms of Substance 
of the Proposed Rule Change

    Cboe Exchange, Inc. (the ``Exchange'' or ``Cboe Options'') proposes 
to amend its ``Consolidated Audit Trail Funding Fees'' \3\ fee schedule 
to establish fees for Industry Members \4\ related to reasonably 
budgeted CAT costs of the National Market System Plan Governing the 
Consolidated Audit Trail (the ``CAT NMS Plan'' or ``Plan'') for the 
period from July 1, 2025 through December 31, 2025. The text of the 
proposed rule change is provided in Exhibit 5.
---------------------------------------------------------------------------

    \3\ The Exchange and each of its affiliated exchanges (Cboe BYX 
Exchange, Inc., Cboe BZX Exchange, Inc., Cboe C2 Exchange, Inc., 
Cboe EDGA Exchange, Inc., and Cboe EDGX Exchange, Inc.) are filing 
to make the same amendment to the ``Consolidated Audit Trail Funding 
Fees'' fee schedule.
    \4\ An ``Industry Member'' is defined as ``a member of a 
national securities exchange or a member of a national securities 
association.'' See Exchange Rule 7.20(u); see also Section 1.1 of 
the CAT NMS Plan. Unless otherwise specified, capitalized terms used 
in this rule filing are defined as set forth in the CAT NMS Plan 
and/or the CAT Compliance Rule. See Chapter 7, Section B of the 
Exchange's Rulebook.

    The text of the proposed rule change is also available on the 
Exchange's website (https://www.cboe.com/us/options/regulation/rule_filings/), at the Exchange's Office of the Secretary, and at the 
Commission's Public Reference Room.

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

    In its filing with the Commission, the Exchange included statements 
concerning the purpose of and basis for the proposed rule change and 
discussed any comments it received on the proposed rule change. The 
text of these statements may be examined at the places specified in 
Item IV below. The Exchange has prepared summaries, set forth in 
sections A, B, and C below, of the most significant aspects of such 
statements.

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

1. Purpose
    On July 11, 2012, the Securities and Exchange Commission (the 
``Commission'') adopted Rule 613 of Regulation NMS, which required the 
self-regulatory organizations (``SROs'') to submit a national market 
system (``NMS'') plan to create, implement and maintain a consolidated 
audit trail that would capture customer and order event information for 
orders in NMS securities across all markets, from the time of order 
inception through routing, cancellation, modification or execution.\5\ 
On November 15, 2016, the Commission approved the CAT NMS Plan.\6\ 
Under the CAT NMS Plan, the Operating Committee has the discretion to 
establish funding for CAT LLC to operate the CAT, including 
establishing fees for Industry Members to be assessed by CAT LLC that 
would be implemented on behalf of CAT LLC by the Participants.\7\ The 
Operating Committee adopted a revised funding model to fund the CAT 
(``CAT Funding Model''). On September 6, 2023, the Commission approved 
the CAT Funding Model after concluding that the model was reasonable 
and that it satisfied the requirements of Section 11A of the Securities 
Exchange Act of 1934 (the ``Exchange Act'') and Rule 608 thereunder.\8\
---------------------------------------------------------------------------

77 FR 45722 (Aug. 1, 2012).
    \6\ Securities Exchange Act Release No. 79318 (Nov. 15, 2016), 
81 FR 84696 (Nov. 23, 2016) (``CAT NMS Plan Approval Order'').
    \7\ Section 11.1(b) of the CAT NMS Plan.

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

    The CAT Funding Model provides a framework for the recovery of the 
costs to create, develop and maintain the CAT, including providing a 
method for allocating costs to fund the CAT among Participants and 
Industry Members. The CAT Funding Model establishes two categories of 
fees: (1) CAT fees assessed by CAT LLC and payable by certain Industry 
Members to recover a portion of historical CAT costs previously paid by 
the Participants (``Historical CAT Assessment'' fees); and (2) CAT fees 
assessed by CAT LLC and payable by Participants and Industry Members to 
fund prospective CAT costs (``CAT Fees'').\9\
---------------------------------------------------------------------------

    \9\ Under the CAT Funding Model, the Operating Committee may 
establish CAT Fees related to CAT costs going forward. Section 
11.3(a) of the CAT NMS Plan. This filing only establishes CAT Fee 
2025-2 related to reasonably budgeted CAT costs for the period from 
July 1, 2025 through December 31, 2025 as described herein; it does 
not address any other potential CAT Fees related to CAT costs. Any 
such other CAT Fee will be subject to a separate fee filing. In 
addition, under the CAT Funding Model, the Operating Committee may 
establish one or more Historical CAT Assessments. Section 11.3(b) of 
the CAT NMS Plan. This filing does not address any Historical CAT 
Assessments.
---------------------------------------------------------------------------

    Under the CAT Funding Model, Participants, CEBBs and CEBSs are 
subject to fees designed to cover the ongoing budgeted costs of the 
CAT, as determined by the Operating Committee. ``The Operating 
Committee

[[Page 30371]]

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').'' \10\ In establishing a CAT 
Fee, the Operating Committee will calculate a ``Fee Rate'' for the 
relevant period. Then, for each month in which a CAT Fee is in effect, 
each CEBB and CEBS would be required to pay the 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 fee for each 
transaction will be calculated by multiplying the number of executed 
equivalent shares in the transaction by one-third and by the Fee 
Rate.\11\
---------------------------------------------------------------------------

    \10\ Section 11.3(a) of the CAT NMS Plan.
    \11\ In approving the CAT Funding Model, the Commission stated 
that, ``[t]he proposed recovery of Prospective CAT Costs is 
appropriate.'' CAT Funding Model Approval Order at 62651.
---------------------------------------------------------------------------

    The CAT Fees to be paid by CEBBs and CEBSs are designed to 
contribute toward the recovery of two-thirds of the budgeted CAT costs 
for the relevant period.\12\ The CAT Funding Model is designed to 
require that the Participants contribute to the recovery of the 
remaining one-third of the budgeted CAT costs.\13\ Participants would 
be subject to the same Fee Rate as CEBBs and CEBSs.\14\ While CAT Fees 
charged to Industry Members become effective in accordance with the 
requirements of Section 19(b) of the Exchange Act,\15\ 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.\16\ Accordingly, this filing does not address Participant CAT 
fees as they are described in the CAT NMS Plan.\17\

    CAT LLC proposes to charge CEBBs and CEBSs (as described in more 
detail below) CAT Fee 2025-2 to recover the reasonably budgeted CAT 
costs for the period from July 1, 2025 through December 31, 2025 in 
accordance with the CAT Funding Model. To implement this fee on behalf 
of CAT LLC, the CAT NMS Plan requires the Participants to ``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.' '' \18\ 
The Plan further states that ``[o]nce 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.'' \19\ 
Accordingly, the purpose of this filing is to implement a CAT Fee on 
behalf of CAT LLC for Industry Members, referred to as CAT Fee 2025-2, 
in accordance with the CAT NMS Plan.

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

(1) CAT Executing Brokers
    CAT Fee 2025-2 will be charged to each CEBB and CEBS for each 
applicable transaction in Eligible Securities.\20\ The CAT NMS Plan 
defines a ``CAT Executing Broker'' to mean:
---------------------------------------------------------------------------

    \20\ In its approval of the CAT Funding Model, the Commission 
determined that charging CAT fees to CAT Executing Brokers was 
reasonable. In reaching this conclusion, the Commission noted that 
the use of CAT Executing Brokers is appropriate because the CAT 
Funding Model is based upon the calculation of executed equivalent 
shares, and, therefore, charging CAT Executing Brokers would reflect 
their executing role in each transaction. Furthermore, the 
Commission noted that, because CAT Executing Brokers are already 
identified in transaction reports from the exchanges and FINRA's 
equity trade reporting facilities recorded in CAT Data, charging CAT 
Executing Brokers could streamline the billing process. CAT Funding 
Model Approval Order at 62629.

    (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.\21\

may, but are not required to, pass-through their CAT Fees to their 
clients, who may, in turn, pass their fees to their clients until 
they are imposed ultimately on the account that executed the 
transaction. See CAT Funding Model Approval Order at 62649.

(2) Calculation of Fee Rate 2025-2
    The Operating Committee determined the Fee Rate to be used in 
calculating CAT Fee 2025-2 (``Fee Rate 2025-2'') by dividing the 
reasonably budgeted CAT costs (``Budgeted CAT Costs 2025-2'') for the 
period from July 1, 2025 through December 31, 2025 (``CAT Fee 2025-2 
Period'') by the reasonably projected total executed share volume of 
all transactions in Eligible Securities for the six-month recovery 
period, as discussed in detail below.\25\ Based on this calculation, 
the Operating Committee has determined that Fee Rate 2025-2 would be 
$0.00002651641828376661 per executed equivalent share. This rate is 
then divided by three and rounded to determine the fee rate of 
$0.000009 per executed equivalent share that will be assessed to CEBBs 
and CEBSs, as also discussed in detail below.
---------------------------------------------------------------------------

    \25\ Section 11.3(a)(i) of the CAT NMS Plan.
---------------------------------------------------------------------------

(A) CAT Fee 2025-2 Period
    CAT LLC proposes to implement CAT Fee 2025-2 as the third CAT Fee 
related to Prospective CAT Costs. CAT LLC proposes to commence CAT Fee 
2025-2 during the year, rather than at the beginning of the year. 
Accordingly, CAT Fee 2025-2 ``would be calculated as described in 
paragraph (II)'' of Section 11.3(a)(i)(A) of the CAT NMS Plan,\26\ 
which states that ``[d]uring 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.'' \27\ For CAT Fee 2025-2, 
the reasonably budgeted CAT costs for ``the remainder of the year'' are 
the reasonably budgeted CAT costs from July 1, 2025 through December 
31, 2025 as set forth in the updated annual budget for 2025 for CAT LLC 
approved by the Operating Committee on May 19, 2025 (``Updated 2025 CAT 
Budget'').\28\

(https://www.catnmsplan.com/sites/default/files/2025-05/05.19.25-CAT-LLC-2025-Financial_and_Operating-Budget.pdf).
---------------------------------------------------------------------------

(B) Executed Equivalent Shares for Transactions in Eligible Securities
    Under 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: (1) each executed share for a 
transaction in NMS Stocks will be counted as one executed equivalent 
share; (2) each executed contract for a transaction in Listed Options 
will be counted based on the multiplier applicable to the specific 
Listed Options (i.e., 100 executed equivalent shares or such other 
applicable multiplier); and (3) each executed share for a transaction 
in OTC Equity Securities will be counted as 0.01 executed equivalent 
share.\29\
---------------------------------------------------------------------------

    \29\ Section 11.3(a)(i)(B) of the CAT NMS Plan. In approving the 
CAT Funding Model, the Commission concluded that ``the use of 
executed equivalent share volume as the basis of the proposed cost 
allocation methodology is reasonable and consistent with the 
approach taken by the funding principles of the CAT NMS Plan.'' CAT 
Funding Model Approval Order at 62640.
---------------------------------------------------------------------------

(C) Budgeted CAT Costs 2025-2
    The CAT NMS Plan states that ``[t]he 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

[[Page 30373]]

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.'' \30\ 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 the prudent operation of the 
Company.'' Section 11.1(a)(i) of the CAT NMS Plan further states that:
---------------------------------------------------------------------------

    \30\ Section 11.3(a)(i)(C) of the CAT NMS Plan.

[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 cost categories as reasonably 
---------------------------------------------------------------------------
determined by the Operating Committee to be included in the budget.

    In accordance with the requirements under the CAT NMS Plan, the 
Operating Committee approved an annual budget for 2025 for CAT LLC 
(``Original 2025 CAT Budget'') in November 2024.\31\ In May 2025, the 
Operating Committee approved an updated budget for 2025, referred to as 
the Updated 2025 CAT Budget. The Updated 2025 CAT Budget includes 
actual costs for each category for the first quarter of 2025, with 
updated estimated costs for each category for the second, third and 
fourth quarters of 2025. The updated costs for the third and fourth 
quarters set forth in the Updated 2025 CAT Budget (i.e., Budgeted CAT 
Costs 2025-2) are the costs used in calculating CAT Fee 2025-2. The 
2025 CAT budgets, both the Original 2025 CAT Budget and the Updated 
2025 CAT Budget, were prepared on the accrual basis of accounting, 
whereas prior CAT budgets were prepared on the cash basis of 
accounting.\32\

    \31\ The Original 2025 CAT Budget is available on the CAT 
website (https://www.catnmsplan.com/sites/default/files/2024-11/11.20.24-CAT-LLC-2025-Financial_and_Operating-Budget.pdf).
    \32\ CAT budgets for periods prior to 2025 were prepared on the 
cash basis of accounting, as such budgets were primarily used to 
determine the dollar amount of promissory notes from the 
Participants that were required to fund the ongoing operations of 
the CAT. Commencing in 2025, with the contemplated recovery of costs 
from Industry Members and the Participants via CAT Fees, the 
Original 2025 CAT Budget was prepared on the accrual basis of 
accounting to properly match projected revenues with estimated 
expenses incurred. A cash basis budget reflects expenditures when 
paid, while an accrual basis budget reflects expenditures when 
incurred. In moving from a cash basis budget to an accrual basis 
budget there is no double counting of expenses.
---------------------------------------------------------------------------

    As described in detail below, the Budgeted CAT Costs 2025-2 would 
be $60,726,412. CEBBs collectively will be responsible for one-third of 
the Budged [sic] CAT Costs 2025-2 (which is $20,242,137.33), and CEBSs 
collectively will be responsible for one-third of the Budgeted CAT 
Costs 2025-2 (which is $20,242,137.33).
    The following describes in detail the Budgeted CAT Costs 2025-2 for 
CAT Fee 2025-2. The following cost details are provided in accordance 
with the requirement in the CAT NMS Plan to provide in the fee filing 
the following:

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.\33\
---------------------------------------------------------------------------

    \33\ Section 11.3(a)(iii)(B) of the CAT NMS Plan.

    Each of the costs described below are reasonable, appropriate and 
necessary for the creation, implementation and maintenance of CAT.
    The following table breaks down the Budgeted CAT Costs 2025-2 into 
the categories set forth in Section 11.3(a)(iii)(B) of the CAT NMS 
Plan.\34\ The Budgeted CAT Costs 2025-2 reflect the costs set forth in 
the third and fourth quarters of the Updated 2025 CAT Budget. The 
Budgeted CAT Costs 2025-2 are the costs used in calculating CAT Fee 
2025-2.
---------------------------------------------------------------------------

    \34\ Note that costs and related cost calculations provided in 
this filing may reflect minor variations from the budgeted costs due 
to rounding.
    \35\ With respect to certain costs that were ``appropriately 
excluded,'' such excluded costs relate to the amortization of 
capitalized technology costs, which are amortized over the life of 
the Plan Processor Agreement. As such costs have already been 
otherwise reflected in the filing, their inclusion would double 
count the capitalized technology costs. In addition, amortization is 
a non-cash expense.

(i) Technology Costs--Cloud Hosting Services
(a) Description of Cloud Hosting Services Costs
    Section 11.3(a)(iii)(B)(B)(1) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to provide a brief description of the 
cloud hosting services costs set forth in the budget. The Operating 
Committee approved an operating budget for the CAT pursuant to Section 
11.1(a) of the CAT NMS Plan that included $82,222,276 in technology 
costs for cloud hosting services for the CAT Fee 2025-2 Period. The 
technology costs for cloud hosting services represent costs reasonably 
budgeted to be incurred for services provided by the cloud services 
provider for the CAT, Amazon Web Services, Inc. (``AWS'') during the 
CAT Fee 2025-2 Period.
---------------------------------------------------------------------------

    \37\ Securities Exchange Act Release No. 101901 (Dec. 12, 2024), 
89 FR 103033 (Dec. 18, 2024) (``Cost Savings Amendment'').
---------------------------------------------------------------------------

    In the agreement between CAT LLC and the Plan Processor for the CAT 
(``Plan Processor Agreement''), FINRA CAT, LLC (``FCAT''), AWS was 
named as the subcontractor to provide cloud hosting services. Under the 
Plan Processor Agreement, CAT LLC is required to pay FCAT the fees 
incurred by the Plan Processor for cloud hosting services provided by 
AWS as FCAT's subcontractor on a monthly basis for the cloud hosting 
services, and FCAT, in turn, pays such fees to AWS. The fees for cloud 
hosting services were negotiated by FCAT on an arm's length basis with 
the goals of managing costs and receiving services required to comply 
with the CAT NMS Plan and Rule 613, taking into consideration a variety 
of factors, including the expected volume of data, the breadth of 
services provided and market rates for similar services. Services 
provided by AWS include storage services, databases, compute services 
and other services (such as networking, management tools and DevOps 
tools), as well as various environments for CAT, such as development, 
performance testing, test, and production environments. FCAT utilizes 
such cloud hosting services for a broad array of services for the CAT, 
such as data ingestion, data management, and analytic tools for the 
CAT. AWS performs cloud hosting services for both the CAT transaction 
database as well as the CAT Customer and Account Information System 
(``CAIS''). It is anticipated that such cloud hosting services will 
continue during the CAT Fee 2025-2 Period.
    The cost for AWS cloud services for the CAT is a function of the 
volume of CAT Data, largely as a result of the processing and storage 
of the CAT Data.\38\ The greater the amount of CAT Data, the greater 
the cost of AWS services to CAT LLC. During the CAT Fee 2025-2 Period, 
it is expected that AWS will provide cloud hosting services for volumes 
of CAT Data far in excess of the volume predictions set forth in the 
CAT NMS Plan. The CAT NMS Plan states, when all CAT Reporters are 
submitting their data to the CAT, it ``must be sized to receive[,] 
process and load more than 58 billion records per day,'' \39\ and that 
``[i]t is expected that the Central Repository will grow to more than 
29 petabytes of raw, uncompressed data.'' \40\ In contrast with those 
estimates, the Q1 2025 data volumes averaged 752 billion events per 
day. The Q1 2025 data volumes reflected a 30% year over year growth 
rate compared to Q1 2024, which averaged 577 billion events per day, 
and reflected a 25% increase from the prior quarter Q4 2024, which 
averaged 602 billion events per day. The highest peak data volume to 
date of 1.45 trillion events was recorded on April 7, 2025. The top 
five peak days were recorded in April 2025.
---------------------------------------------------------------------------

    \38\ In addition to the effect of the data volume on the cloud 
hosting costs, the processing timelines set forth in the Plan 
contribute to the cloud hosting costs. For further discussion of the 
effect of processing timelines on cloud hosting costs, see Section 
3(b)(2)(A)(i) below.
    \39\ Appendix D-4 of the CAT NMS Plan at n.262.
    \40\ Appendix D-5 of the CAT NMS Plan.
---------------------------------------------------------------------------

    CAT LLC estimates that the budget for cloud hosting services costs 
during the CAT Fee 2025-2 Period will be approximately $82,222,276. The 
budget for cloud hosting services costs during the CAT Fee 2025-2 
Period is calculated based on the Updated 2025 CAT Budget. 
Specifically, this estimate was calculated by adding the budgeted 
amounts for cloud hosting services costs for the third and fourth 
quarters of 2025 as set forth in the Updated 2025 CAT Budget.\41\
---------------------------------------------------------------------------

    \41\ This calculation is $40,362,043 + $41,860,233 = 
$82,222,276.
---------------------------------------------------------------------------

    CAT LLC estimated the budget for the cost for cloud hosting 
services for the

[[Page 30376]]

CAT Fee 2025-2 Period based on an assumption of 40% annual year-over-
year volume growth for the transaction database and an assumption of 5% 
annual year-over-year volume growth for CAIS. CAT LLC determined these 
growth assumptions in coordination with FCAT based on an analysis of a 
variety of existing data and alternative growth scenarios. In 
particular, in determining to use the 40% annual year-over-year volume 
growth in events per day, CAT LLC considered, among other things, the 
average annual year-over-year volume growth for 2019 through 2024 of 
approximately 45%, the average annual year-over-year volume growth for 
2020 through 2024 of approximately 30%, and the average monthly growth 
rate for 2024 of approximately 50%.\42\
---------------------------------------------------------------------------

    \42\ Note that these growth rates are based on events processed 
and stored in the CAT. Executed transactions are a small subset of 
such events. As a result, the number of transactions in the CAT, 
and, hence, the number of executed equivalent shares, is not 
directly correlated with the number of events processed in the CAT 
or the costs of cloud hosting services for the CAT. Accordingly, the 
number of executed equivalent shares may stay relatively constant 
from year to year while the number of events processed and stored in 
the CAT may grow significantly.
---------------------------------------------------------------------------

    This process for estimating the budget for cloud hosting services 
costs for the CAT Fee 2025-2 Period is the same process by which CAT 
LLC estimated the cloud hosting services costs for the Original 2025 
CAT Budget. The Original 2025 CAT Budget estimated a budget for cloud 
hosting services of $39,640,542 for the first quarter of 2025. The 
actual costs for cloud hosting services for the first quarter of 2025, 
which are set forth in the Updated 2025 CAT Budget, were $36,357,017. 
Therefore, the variance between budgeted and actual cloud hosting 
services costs for this period was an approximate decrease of 8%. 
Accordingly, CAT LLC believes that the process for estimating the 
budgeted cloud hosting services costs for the CAT Fee 2025-2 Period is 
reasonable.
(b) Changes From Prior Fee Filing
    Section 11.3(a)(iii)(B)(B) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to describe the reason for changes in 
the line item for cloud hosting services costs from the prior CAT Fee 
filing. Accordingly, this filing describes the changes in the cloud 
hosting services costs from the Original 2025 CAT Budget, which was 
used in the calculation of the prior Prospective CAT Fee, CAT Fee 2025-
1.\43\ Specifically, the following describes the differences (if any) 
in the costs for cloud hosting services as set forth in the Original 
2025 CAT Budget versus the Updated 2025 CAT Budget for the full year of 
2025 as well as for the third and fourth quarters of 2025, and the 
reasons for any changes.

    \43\ Fee Filing for CAT Fee 2025-1.
---------------------------------------------------------------------------

    The annual 2025 budgeted costs for cloud hosting services as set 
forth in the Original 2025 CAT Budget were $182,594,630, and the annual 
2025 budgeted costs for cloud hosting services as set forth in the 
Updated 2025 CAT Budget are $159,230,937. Accordingly, budgeted annual 
costs for cloud hosting services decreased by $23,363,693 from the 
Original 2025 CAT Budget to the Updated 2025 CAT Budget, which is an 
approximate 13% reduction in cloud hosting services costs for the full 
year of 2025.
    Correspondingly, the budgeted costs for cloud hosting services for 
the third and fourth quarters of 2025 as set forth in the Original 2025 
CAT Budget were $97,748,713,\44\ and the budgeted costs for cloud 
hosting services for third and fourth quarters of 2025 as set forth in 
the Updated 2025 CAT Budget are $82,222,276.\45\ Accordingly, the 
budgeted costs for cloud hosting services for the third and fourth 
quarters of 2025 decreased by $15,526,437 from the Original 2025 CAT 
Budget to the Updated 2025 CAT Budget, which is approximately a 16% 
reduction in cloud hosting services costs for the third and fourth 
quarters of 2025.
---------------------------------------------------------------------------

    \44\ This calculation is $46,382,724 + $51,365,989 = 
$97,748,713.
    \45\ This calculation is $40,362,043 + $41,860,233 = 
$82,222,276.
---------------------------------------------------------------------------

    The decrease in costs for cloud hosting services from the Original 
2025 CAT Budget to the Updated 2025 CAT Budget, both for the full year 
for 2025 and for the third and fourth quarters of 2025, reflects (1) a 
decrease in costs related to changes made pursuant to the Cost Savings 
Amendment; (2) cost decreases related to optimizations resulting in 
reduced procesing [sic] and storage costs; and (3) volume increases 
below the initial projection.
(ii) Technology Costs--Operating Fees
(a) Description of Operating Fees
    Section 11.3(a)(iii)(B)(B)(1) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to provide a brief description of the 
operating fees set forth in the budget. The Operating Committee 
approved an operating budget for the CAT pursuant to Section 11.1(a) of 
the CAT NMS Plan that included $15,453,942 in technology costs for 
operating fees for the CAT Fee 2025-2 Period. Operating fees are those 
fees paid by CAT LLC to FCAT as the Plan Processor to operate and 
maintain the CAT and to perform business operations related to the 
system, including compliance, security, testing, training, 
communications with the industry (e.g., management of the FINRA CAT 
Helpdesk, FAQs, website and webinars) and program management as 
required by the CAT NMS Plan. Operating fees also include market data 
provider costs, as discussed below.
    Plan Processor: FCAT. Under the Plan Processor Agreement with FCAT, 
CAT LLC is required to pay FCAT a negotiated monthly fixed price for 
the operation of the CAT. This fixed price contract was negotiated on 
an arm's length basis with the goals of managing costs and receiving 
services required to comply with the CAT NMS Plan and Rule 613, taking 
into consideration a variety of factors, including the breadth of 
services provided and market rates for similar types of activity. It is 
anticipated that FCAT will provide a variety of services to the CAT 
during the CAT Fee 2025-2 Period, including the following:
     Provide the CAT-related functions and services as the Plan 
Processor as required by SEC Rule 613 and the CAT NMS Plan in 
connection with the operation and maintenance of the CAT;
     Address compliance items, including drafting CAT policies 
and procedures, and addressing Regulation SCI requirements;
     Provide support to the Operating Committee, the Compliance 
Subcommittee and CAT working groups;
     Assist with interpretive efforts, exemptive requests and 
amendments regarding the CAT NMS Plan;
     Oversee the security of the CAT;
     Monitor the operation of the CAT, including with regard to 
Participant and Industry Member reporting;
     Provide support to subcontractors under the Plan Processor 
Agreement;
     Provide support in discussions with the Participants and 
the SEC and its staff;
     Operate the FINRA CAT Helpdesk;
     Facilitate communications with the industry, including via 
FAQs, CAT Alerts, meetings, presentations and webinars;
     Administer the CAT website and all of its content;
     Maintain cyber security insurance related to the CAT;
     Assist with billing, collection and other CAT fee-related 
activity; and
     Provide technical support and assistance with 
connectivity, data access, and user support, including the use of CAT 
Data and query tools, for Participants and the SEC staff.

    CAT LLC calculated the budget for the FCAT technology costs for 
operating fees for the CAT Fee 2025-2 Period based on the recurring 
monthly operating fees under the Plan Processor Agreement.
    Market Data Provider: Algoseek. It is anticipated that the 
operating fees costs for the CAT Fee 2025-2 Period will include costs 
related to the receipt of certain market data for the CAT pursuant to 
an agreement between FCAT and Algoseek, LLC (``Algoseek''). CAT LLC 
determined that Algoseek would provide market data that included data 
elements set forth in Section 6.5(a)(ii) of the CAT NMS Plan, and that 
the fees were reasonable and in line with market rates for the market 
data received. All costs under the contract would be treated as a 
direct pass through cost to CAT LLC. CAT LLC estimated the budget for 
the costs for Algoseek for the CAT Fee 2025-2 Period based on the 
monthly rate set forth in the agreement between Algoseek and FCAT.
    Operating Fee Estimates. CAT LLC estimates that the budget for 
operating fees during the CAT Fee 2025-2 Period will be approximately 
$15,453,942. The budget for operating fees during the CAT Fee 2025-2 
Period is calculated based on the Updated 2025 CAT Budget. 
Specifically, this estimate was calculated by adding the budgeted 
amounts for operating fees for the third and fourth quarters of 2025 as 
set forth in the Updated 2025 CAT Budget.\46\
---------------------------------------------------------------------------

    \46\ This calculation is ($7,225,473 + $7,225,473) + ($501,498 + 
$501,498) = $15,453,942.
---------------------------------------------------------------------------

    As discussed above, CAT LLC estimated the budget for the operating 
fees during the CAT Fee 2025-2 Period based on monthly rates set forth 
in the Plan Processor Agreement and the agreement with Algoseek. CAT 
LLC also recognized that the operating fees are generally consistent 
throughout the year. This process for estimating the budget for the 
operating fees for the CAT Fee 2025-2 Period is the same process by 
which CAT LLC estimated the operating fees for the Original 2025 CAT 
Budget. The Original 2025 CAT Budget estimated a budget for operating 
fees of $7,662,270 for the first quarter of 2025.\47\ The actual costs 
for operating fees for first quarter of 2025 were $7,636,774.\48\ 
Therefore, the variance between budgeted and actual operating fees for 
this period was not material. Accordingly, CAT LLC believes that the 
process for estimating the budgeted operating fees for the CAT Fee 
2025-2 Period is reasonable.
---------------------------------------------------------------------------

    \47\ This calculation is $7,221,522 + $440,748 = $7,662,270.
    \48\ This calculation is $7,196,026 + $440,748 = $7,636,774.
---------------------------------------------------------------------------

(b) Changes From Prior Fee Filing
    Section 11.3(a)(iii)(B)(B) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to describe the reason for changes in 
the line item for operating fees from the prior CAT Fee filing. 
Accordingly, this filing describes the changes from the operating fees 
set forth in the Original 2025 CAT Budget, which was used in the 
calculation of the prior Prospective CAT Fee, CAT Fee 2025-1.\49\ 
Specifically, the following describes the differences (if any) in the 
costs for operating fees as set forth in the Original 2025 CAT Budget 
versus the Updated 2025 CAT Budget for the full year of 2025 as well as 
for the third and fourth quarters of 2025, and the reasons for any 
changes.
---------------------------------------------------------------------------

    \49\ See Fee Filing for CAT Fee 2025-1.
---------------------------------------------------------------------------

    The annual 2025 budgeted costs for operating fees as set forth in 
the Original 2025 CAT Budget were $30,831,330,\50\ and the annual 2025 
budgeted costs for operating fees as set forth in the Updated 2025 CAT 
Budget are $30,817,686 \51\ Accordingly, budgeted annual costs for 
operating fees did not change materially from the Original 2025 CAT 
Budget to the Updated 2025 CAT Budget for the full year of 2025.
---------------------------------------------------------------------------

    \50\ This calculation is $28,886,088 + $1,945,242 = $30,831,330.
    \51\ This calculation is $28,872,444 + $1,945,242 = $30,817,686.
---------------------------------------------------------------------------

    Correspondingly, the budgeted costs for operating fees for the 
third and fourth quarters of 2025 as set forth in the Original 2025 CAT 
Budget were $15,446,040,\52\ and the budgeted costs for operating fees 
for the third and fourth quarters of 2025 as set forth in the Updated 
2025 CAT Budget are $15,453,942.\53\ Accordingly, the budgeted costs 
for operating fees for the third and fourth quarters of 2025 did not 
change materially from the Original 2025 CAT Budget to the Updated 2025 
CAT Budget for the third and fourth quarters of 2025.
---------------------------------------------------------------------------

    \52\ This calculation is ($7,221,522 + $7,221,522) + ($501,498 + 
$501,498) = $15,446,040.
    \53\ This calculation is ($7,225,473 + $7,225,473) + ($501,498 + 
$501,498) = $15,453,942.
---------------------------------------------------------------------------

(iii) Technology Costs--CAIS Operating Fees
(a) Description of CAIS Operating Fees
    Section 11.3(a)(iii)(B)(B)(1) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to provide a brief description of the 
CAIS operating fees set forth in the budget. The Operating Committee 
approved an operating budget for the CAT pursuant to Section 11.1(a) of 
the CAT NMS Plan that included $10,374,924 in technology costs for CAIS 
operating fees for the CAT Fee 2025-2 Period. CAIS operating fees 
represent the fees paid to FCAT for services provided with regard to 
the operation and maintenance of CAIS, and to perform the business 
operations related to the system, including compliance, security, 
testing, training, communications with the industry (e.g., management 
of the FINRA CAT Helpdesk, FAQs, website and webinars) and program 
management. The CAT is required under the CAT NMS Plan to capture and 
store Customer Identifying Information and Customer Account Information 
in a database separate from the transactional database and to create a 
CAT-Customer-ID for each Customer. As of May 31, 2024, the 
implementation of CAIS was completed.\54\
---------------------------------------------------------------------------

    \54\ For a discussion of the implementation timeline for CAIS, 
see CAT Alert 2023-01.
---------------------------------------------------------------------------

    During the CAT Fee 2025-2 Period, it is anticipated that FCAT will 
provide CAIS-related services. Under the Plan Processor Agreement with 
FCAT, CAT LLC is required to pay FCAT for CAIS-related services 
provided by FCAT on a monthly basis. CAT LLC negotiated the fees for 
FCAT's CAIS-related services on an arm's length basis with the goals of 
managing costs and receiving services required to comply with the CAT 
NMS Plan, taking into consideration a variety of factors, including the 
services to be provided and market rates for similar types of activity. 
During the CAT Fee 2025-2 Period, it is anticipated that FCAT will 
continue to provide services relating to the ongoing operation, 
maintenance and support of CAIS.
    CAT LLC estimates that the budget for CAIS operating fees during 
the CAT Fee 2025-2 Period will be approximately $10,374,924. The budget 
for CAIS operating fees during the CAT Fee 2025-2 Period is calculated 
based on the Updated 2025 CAT Budget. Specifically, this estimate was 
calculated by adding the budgeted amounts for CAIS operating fees for 
the third and fourth quarters of 2025 as set forth in the Updated 2025 
CAT Budget.\55\
---------------------------------------------------------------------------

    \55\ This calculation is $5,187,462 + $5,187,462 = $10,374,924.
---------------------------------------------------------------------------

    CAT LLC calculated the budget for FCAT's CAIS-related services for 
the CAT Fee 2025-2 Period based on the recurring monthly CAIS operating 
fees under the Plan Processor Agreement. This process for estimating 
the budget for the CAIS operating fees for the CAT Fee 2025-2 Period is 
the same process by which CAT LLC estimated the CAIS operating fees for 
the Original 2025 CAT Budget. The Original 2025 CAT Budget

[[Page 30378]]

estimated a budget of $5,187,462 for CAIS operating fees for the first 
quarter of 2025. The actual costs for CAIS operating fees for the first 
quarter of 2025, which are set forth in the Updated 2025 CAT Budget, 
were $5,187,462. There was no variance between budgeted and actual CAIS 
operating fees for the first quarter of 2025. Accordingly, CAT LLC 
believes that the process for estimating the budgeted CAIS operating 
fees for the CAT Fee 2025-2 Period is reasonable.
(b) Changes From Prior Fee Filing
    Section 11.3(a)(iii)(B)(B) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to describe the reason for changes in 
the line item for CAIS operating fees from the prior CAT Fee filing. 
Accordingly, this filing describes the changes in CAIS operating fees 
from the Original 2025 CAT Budget, which was used in the calculation of 
the prior Prospective CAT Fee, CAT Fee 2025-1.\56\ Specifically, the 
following describes the differences (if any) in the costs for CAIS 
operating fees as set forth in the Original 2025 CAT Budget versus the 
Updated 2025 CAT Budget for the full year of 2025 as well as for the 
third and fourth quarters of 2025, and the reasons for any changes.
---------------------------------------------------------------------------

    \56\ See Fee Filing for CAT Fee 2025-1.
---------------------------------------------------------------------------

    CAIS operating fees are based on a recurring monthly rate payable 
to FCAT and are unchanged from the prior CAT Fee filing. The annual 
2025 budgeted costs for CAIS operating fees as set forth in the 
Original 2025 CAT Budget were $20,749,848, and the annual 2025 budgeted 
costs for CAIS operating fees as set forth in the Updated 2025 CAT 
Budget are $20,749,848. Accordingly, the budgeted annual costs for CAIS 
operating fees are the same for both the Original 2025 CAT Budget and 
the Updated 2025 CAT Budget.
    Correspondingly, the budgeted costs for CAIS operating fees for the 
third and fourth quarters of 2025 as set forth in the Original 2025 CAT 
Budget were $10,374,924, and the budgeted costs for CAIS operating fees 
for the third and fourth quarters of 2025 as set forth in the Updated 
2025 CAT Budget are $10,374,924.\57\ Accordingly, the budget costs for 
CAIS operating fees for the third and fourth quarters of 2025 are the 
same for both the Original 2025 CAT Budget and the Updated 2025 CAT 
Budget.
---------------------------------------------------------------------------

    \57\ This calculation is $5,187,462 + $5,187,462 = $10,374,924, 
for both the Original 2025 CAT Budget and the Updated 2025 CAT 
Budget.
---------------------------------------------------------------------------

    Accordingly, there were no changes in the line item for CAIS 
operating fees from the prior CAT Fee filing.
(iv) Technology Costs--Change Request Fees
(a) Description of Change Request Fees
    Section 11.3(a)(iii)(B)(B)(1) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to provide a brief description of the 
change request fees set forth in the budget. The Operating Committee 
approved an operating budget for the CAT pursuant to Section 11.1(a) of 
the CAT NMS Plan that included $500,000 in technology costs for change 
request fees for the CAT Fee 2025-2 Period. The technology costs 
related to change request fees include costs related to certain 
modifications, upgrades or other changes to the CAT.
    Change requests are standard practice and necessary to reflect 
operational changes, including changes related to new market 
developments, such as new market participants. In general, if CAT LLC 
determines that a modification, upgrade or other changes to the 
functionality or service is necessary and appropriate, CAT LLC will 
submit a request for such a change to the Plan Processor. The Plan 
Processor will then respond to the request with a proposal for 
implementing the change, including the cost (if any) of such a change. 
CAT LLC then determines whether to approve the proposed change.
    The change request budget line is established to include expected 
costs to be incurred in which the nature of the costs (i.e., 
capitalization versus expensing) have not yet been determined. Upon the 
incurrence of such costs, the final determination of capitalization 
versus expensing is determined and then such costs are reclassified 
from the change request line to the appropriate technology cost line 
item.
    During the CAT Fee 2025-2 Period, it is anticipated that CAT LLC 
will engage FCAT to pursue certain change requests in accordance with 
the Plan Processor Agreement. The budget for change requests for the 
CAT Fee 2025-2 Period includes a placeholder of $500,000 for potential 
change request fees that may be necessary in accordance with the Plan 
Processor Agreement. The placeholder amount was determined based on 
prior experience with change requests related to the CAT.
    CAT LLC estimates that the budget for change requests during the 
CAT Fee 2025-2 Period will be approximately $500,000. The budget for 
change requests during the CAT Fee 2025-2 Period is calculated based on 
the Updated 2025 CAT Budget. Specifically, this estimate was calculated 
by adding the budgeted amounts for the change requests for the third 
and fourth quarters of 2025 as set forth in the Updated 2025 CAT 
Budget.\58\
---------------------------------------------------------------------------

    \58\ This calculation is $250,000 + $250,000 = $500,000.
---------------------------------------------------------------------------

    CAT LLC estimated the budget for the potential change requests for 
the CAT Fee 2025-2 Period based on, among other things, a review of 
past change requests and potential future change request needs, as well 
as discussions with FCAT. This process for estimating the budget for 
the change requests for the CAT Fee 2025-2 Period is the same process 
by which CAT LLC estimated the change requests cost for the Original 
2025 CAT Budget. The Original 2025 CAT Budget estimated a change 
request budget of $0 for the the [sic] first quarter of 2025. The 
actual costs for change requests for the first quarter of 2025, which 
are set forth in the Updated 2025 CAT Budget, were $0. There was no 
variance between budgeted and actual change request costs for the first 
quarter of 2025. Accordingly, CAT LLC believes that the process for 
estimating the budgeted change request costs for 2025 is reasonable.
(b) Changes From Prior Fee Filing
    Section 11.3(a)(iii)(B)(B) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to describe the reason for changes in 
the line item for change request fees from the prior CAT Fee filing. 
Accordingly, this filing describes the changes in the change request 
fees from the Original 2025 CAT Budget, which was used in the 
calculation of the prior Prospective CAT Fee, CAT Fee 2025-1.\59\ 
Specifically, the following describes the differences (if any) in the 
costs for change requests as set forth in the Original 2025 CAT Budget 
versus the Updated 2025 CAT Budget for the full year of 2025 as well as 
for the third and fourth quarters of 2025, and the reasons for any 
changes.
---------------------------------------------------------------------------

    \59\ See Fee Filing for CAT Fee 2025-1.
---------------------------------------------------------------------------

    The annual 2025 budgeted costs for change requests as set forth in 
the Original 2025 CAT Budget were $750,000, and the annual 2025 
budgeted costs for change requests as set forth in the Updated 2025 CAT 
Budget are $750,000. Accordingly, budgeted annual costs for change 
requests are the same for both the Original 2025 CAT Budget and the 
Updated 2025 CAT Budget.
    Correspondingly, the budgeted costs for change requests for the 
third and fourth quarters of 2025 as set forth in the Original 2025 CAT 
Budget were $500,000, and the budgeted costs for change request for the 
third and fourth quarters of 2025 as set forth in the Updated 2025 CAT 
Budget are

[[Page 30379]]

$500,000.\60\ Accordingly, the budgeted costs for change requests for 
the third and fourth quarters of 2025 are the same for both the 
Original 2025 CAT Budget and the Updated 2025 CAT Budget.
---------------------------------------------------------------------------

    \60\ This calculation is $250,000 + $250,000 = $500,000, for 
both the Original 2025 CAT Budget and the Updated 2025 CAT Budget.
---------------------------------------------------------------------------

    Accordingly, there were no changes in the line item for change 
requests from the prior CAT Fee filing.
(v) Technology Costs--Capitalized Developed Technology Costs
(a) Description of Capitalized Developed Technology Costs
    Section 11.3(a)(iii)(B)(B)(1) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to provide a brief description of the 
capitalized developed technology costs set forth in the budget. The 
Operating Committee approved an operating budget for the CAT pursuant 
to Section 11.1(a) of the CAT NMS Plan that includes $0 in technology 
costs for capitalized developed technology costs for the CAT Fee 2025-2 
Period. This category of costs includes the budget for capitalizable 
application development costs incurred in the development of the CAT. 
It is anticipated that such costs will include certain costs related to 
the software license fee for CAIS in accordance with the Plan Processor 
Agreement with FCAT, as well as costs related to a set of technology 
changes to be implemented by FCAT.
    CAT LLC estimates that the budget for capitalized developed 
technology costs during the CAT Fee 2025-2 Period will be approximately 
$0. The budget for capitalized developed technology costs during the 
CAT Fee 2025-2 Period is calculated based on the Updated 2025 CAT 
Budget. Specifically, this estimate was calculated by adding the 
budgeted amounts for capitalized developed technology costs for the 
third and fourth quarters of 2025 as set forth in the Updated 2025 CAT 
Budget.\61\
---------------------------------------------------------------------------

    \61\ This calculation is ($0 + $0) + ($0 + $0) = $0.
---------------------------------------------------------------------------

    CAT LLC estimated the budget for capitalized developed technology 
costs for the CAT Fee 2025-2 Period based on an analysis of a variety 
of factors, including information related to potential technology costs 
and related contractual and Plan requirements, and discussions with 
FCAT regarding such potential technology costs. This process for 
estimating the budget for capitalized developed technology costs for 
the CAT Fee 2025-2 Period is the same process by which CAT LLC 
estimated the capitalized developed technology costs for the Original 
2025 CAT Budget. The Original 2025 CAT Budget estimated a budget for 
capitalized developed technology costs of $3,923,360 for the first 
quarter of 2025.\62\ The actual costs for capitalized developed 
technology costs for the first quarter of 2025 were $4,871,962.\63\ The 
budgeted costs and the actual costs for the line item of capitalized 
developed technology costs for the first quarter of 2025 were the same: 
$1,150,000. As a result, this variance is attributable to software 
license fees, which is the the [sic] other line item included in the 
capitalized developed technology costs for Budgeted CAT Fees 2025-2. 
The variance of $948,602 is the result of costs related to the software 
license fee for CAIS in accordance with the Plan Processor Agreement 
with FCAT. Accordingly, CAT LLC believes that the process for 
estimating the budgeted capitalized developed technology costs for the 
CAT Fee 2025-2 Period is reasonable.
---------------------------------------------------------------------------

    \62\ This calculation is $1,150,000 + $2,773,360 = $3,923,360.
    \63\ This calculation is $1,150,000 + $3,721,962 = $4,871,962.
---------------------------------------------------------------------------

(b) Changes From Prior Fee Filing
    Section 11.3(a)(iii)(B)(B) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to describe the reason for changes in 
the line item for capitalized developed technology costs from the prior 
CAT Fee filing. Accordingly, this filing describes the changes in the 
capitalized developed technology costs from the Original 2025 CAT 
Budget, which was used in the calculation of the prior Prospective CAT 
Fee, CAT Fee 2025-1.\64\ Specifically, the following describes the 
differences (if any) in the costs for capitalized developed technology 
costs as set forth in the Original 2025 CAT Budget versus the Updated 
2025 CAT Budget for the full year of 2025 as well as for the third and 
fourth quarters of 2025, and the reasons for any changes.
---------------------------------------------------------------------------

    \64\ See Fee Filing for CAT Fee 2025-1.
---------------------------------------------------------------------------

    The annual 2025 budget for capitalized developed technology costs 
as set forth in the Original 2025 CAT Budget were $3,923,360,\65\ and 
the annual 2025 budget for capitalized developed technology costs as 
set forth in the Updated 2025 CAT Budget are $4,871,962.\66\ 
Accordingly, the annual budget for capitalized developed technology 
costs increased by $948,602 from the Original 2025 CAT Budget to the 
Updated 2025 CAT Budget for the full year of 2025. This increase in the

for the third and fourth quarters of 2025 as set forth in the Original 
2025 CAT Budget was $0,\67\ and the budgeted capitalized developed 
technology costs for the third and fourth quarters of 2025 as set forth

(vi) Legal Costs
(a) Description of Legal Costs
    Section 11.3(a)(iii)(B)(B)(2) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to provide a brief description of the 
legal costs set forth in the budget. The Operating Committee approved 
an operating budget for the CAT pursuant to Section 11.1(a) of the CAT 
NMS Plan that includes $3,631,342 in legal costs for the CAT Fee 2025-2 
Period. This category of costs represents budgeted costs for legal 
services for this period. CAT LLC anticipates that it will receive 
legal services from two law firms, Wilmer Cutler Pickering Hale and 
Dorr LLP (``WilmerHale'') and Jenner & Block LLP (``Jenner''), during 
the CAT Fee 2025-2 Period.
    Law Firm: WilmerHale. It is anticipated that legal costs during the 
CAT Fee 2025-2 Period will include costs related to the legal services 
performed by WilmerHale. CAT LLC anticipates that it will continue to 
employ WilmerHale during the CAT Fee 2025-2 Period based on, among 
other things, their expertise, long history with the project and 
recognition that the hourly fee rates for this law firm are anticipated 
to be in line with market rates for specialized legal expertise. 
WilmerHale's billing rates are negotiated on an annual basis and are 
determined with reference to the rates charged by other leading law 
firms for similar work. The Participants assess WilmerHale's 
performance and review prospective budgets and staffing plans submitted 
by WilmerHale on an annual basis. The legal fees will be paid by CAT 
LLC to WilmerHale.
    During the CAT Fee 2025-2 Period, it is anticipated that WilmerHale 
will provide legal services related to the following:

the CAT Fee 2025-2 Period through an analysis of a variety of factors, 
including WilmerHale fee rates, historical legal fees, and information 
related to pending legal issues and potential future legal issues.

things, their expertise, history with the project and recognition that 
their hourly fee rates are in line with market rates for specialized 
legal expertise. The legal fees will be paid by CAT LLC to Jenner.
    During the CAT Fee 2025-2 Period, it is anticipated that Jenner 
will continue to provide legal assistance to CAT LLC regarding certain 
litigation matters, including: (1) CAT LLC's defense against a lawsuit 
filed in the Western District of Texas against the SEC Chair, the SEC

the CAT Funding Model; \70\ and (3) a lawsuit in the Eleventh Circuit 
filed by Citadel Securities LLC seeking review of the SEC's May 20, 
2024 order \71\ granting the Participants temporary conditional 
exemptive relief related to the reporting of bids and/or offers made in 
response to a request for quote or other form of solicitation response 
provided in standard electronic format that is not immediately 
actionable.\72\ Litigation involving CAT LLC is an expense of operating 
the CAT, and, therefore, is appropriately an obligation of both 
Participants and Industry Members under the CAT Funding Model.

CAT Fee 2025-2 Period through an analysis of a variety of factors, 
including Jenner's fee rates, historical legal fees, and information 
related to pending legal issues and potential future legal issues.
    Legal Cost Estimates. CAT LLC estimates that the budget for legal 
services during the CAT Fee 2025-2 Period will be approximately 
$3,631,342. The budget for legal services during the CAT Fee 2025-2 
Period is calculated based on the Updated 2025 CAT Budget. 
Specifically, this estimate was calculated by adding the budgeted 
amounts for the legal services for the third and fourth quarters of 
2025 as set forth in the Updated 2025 CAT Budget.\73\
---------------------------------------------------------------------------

    \73\ This calculation is $1,815,671 + $1,815,671 = $3,631,342.
---------------------------------------------------------------------------

    CAT LLC estimated the budget for the legal services for the CAT Fee 
2025-2 Period based on an analysis of a variety of factors, including 
law firm fee rates, historical legal fees, and information related to 
pending legal issues and potential future legal issues. This process 
for estimating the budget for the legal services for CAT Fee 2025-2 
Period is the same process by which CAT LLC estimated the legal cost 
for the Original 2025 CAT Budget. The Original 2025 CAT Budget 
estimated a budget for legal costs of $1,430,000 for the first quarter 
of 2025. The actual costs for legal services for the first quarter of 
2025, which are set forth in the Updated 2025 Budget, were $1,922,990. 
The increase of $492,990 was due to unanticipated issues that required 
additional legal efforts on behalf of CAT LLC that developed after the 
budget was created. Such additional costs were primarily due to 
additional legal work in responding to an SEC examination related to 
the CAT, for commercial contract-related matters, including with regard 
to the Plan Processor Agreement, and related to cost savings 
initiatives. Accordingly, CAT LLC believes that the process for 
estimating the budgeted legal costs for the CAT Fee 2025-2 Period is 
reasonable.
(b) Changes From Prior Fee Filing
    Section 11.3(a)(iii)(B)(B) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to describe the reason for changes in 
the line item for legal costs from the prior CAT Fee filing. 
Accordingly, this filing describes the changes in the legal costs from 
the Original 2025 CAT Budget, which was used in the calculation of the 
prior Prospective CAT Fee, CAT Fee 2025-1.\74\ Specifically, the 
following describes the differences (if any) in the legal costs as set 
forth in the Original 2025 CAT Budget versus the Updated 2025 CAT 
Budget for the full year of 2025 as well as for the third and fourth 
quarters of 2025, and the reasons for any changes.
---------------------------------------------------------------------------

    \74\ See Fee Filing for CAT Fee 2025-1.
---------------------------------------------------------------------------

    The annual 2025 budgeted legal costs as set forth in the Original 
2025 CAT Budget were $5,720,000, and the annual 2025 budgeted legal 
costs as set forth in the Updated 2025 CAT Budget are $7,370,002. 
Accordingly, the annual budget for legal costs increased by $1,650,002 
from the Original 2025 CAT Budget to the Updated 2025 CAT Budget for 
the full year of 2025.
    Correspondingly, the budgeted legal costs for the third and fourth 
quarters of 2025 as set forth in the Original 2025 CAT Budget were 
$2,860,000,\75\ and the budgeted legal costs for the third and fourth 
quarters of 2025 as set forth in the Updated 2025 CAT Budget are 
$3,631,342.\76\ Accordingly, the budget for legal costs for the third 
and fourth quarters of 2025 increased by $771,342 from the Original 
2025 CAT Budget to the Updated 2025 CAT Budget for the third and fourth 
quarters of 2025.
---------------------------------------------------------------------------

    \75\ This calculation is $1,430,000 + $1,430,000 = $2,860,000.
    \76\ This calculation is $1,815,671 + $1,815,671 = $3,631,342.
---------------------------------------------------------------------------

    This budgeted increase in the legal costs in the Updated 2025 CAT 
Budget

[[Page 30381]]

from the Original 2025 Budget, both for the full year for 2025 and for 
the third and fourth quarters of 2025, was primarily due to an 
anticipated increase in legal costs related to litigation matters as 
well as regulatory and corporate legal matters.
(vii) Consulting Costs
(a) Description of Consulting Costs
    Section 11.3(a)(iii)(B)(B)(3) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to provide a brief description of the 
consulting costs set forth in the budget. The Operating Committee 
approved an operating budget for the CAT pursuant to Section 11.1(a) of 
the CAT NMS Plan that included $866,167 in consulting costs for the CAT 
Fee 2025-2 Period. The consulting costs represent the fees estimated to 
be paid to the consulting firm Deloitte & Touche LLP (``Deloitte'') as 
project manager during the CAT Fee 2025-2 Period. These consulting 
costs include costs for advisory services related to the operation of 
the CAT, and meeting facilitation and communications coordination, 
vendor support and financial analyses.
    It is anticipated that the costs for CAT during the CAT Fee 2025-2 
Period will include costs related to consulting services performed by 
Deloitte. CAT LLC anticipates that it will continue to employ Deloitte 
during the CAT Fee 2025-2 Period based on, among other things, their 
expertise, long history with the project, and the recognition that it 
is anticipated that the consulting fees will remain in line with market 
rates for this type of specialized consulting work. Deloitte's fee 
rates are negotiated on an annual basis. CAT LLC assesses Deloitte's 
performance and reviews prospective budgets and staffing plans 
submitted by Deloitte on an annual basis. The consulting fees will be 
paid by CAT LLC to Deloitte.
    It is anticipated that Deloitte will provide a variety of 
consulting services to the CAT during the CAT Fee 2025-2 Period, 
including the following:
     Implement program operations for the CAT project;
     Provide support to the Operating Committee, the Chair of 
the Operating Committee and the Leadership Team, including project 
management support, coordination and planning for meetings and 
communications, and interfacing with law firms and the SEC;
     Assist with cost and funding matters for the CAT, 
including assistance with loans and the CAT bank account for CAT 
funding;
     Provide support for updating the SEC on the progress of 
the development of the CAT; and
     Provide support for third party vendors for the CAT, 
including FCAT, Anchin and the law firms engaged by CAT LLC.
    In addition, the consulting costs include the compensation for the 
Chair of the CAT Operating Committee.
    CAT LLC estimates that the budget for consulting costs during the 
CAT Fee 2025-2 Period will be approximately $866,167. The budget for 
consulting costs during the CAT Fee 2025-2 Period is calculated based 
on the Updated 2025 CAT Budget. Specifically, this estimate was 
calculated by adding the budgeted amounts for consulting services for 
the third and fourth quarters of 2025 as set forth in the Updated 2025 
CAT Budget.\77\
---------------------------------------------------------------------------

    \77\ This calculation is $433,084 + $433,083 = $866,167.
---------------------------------------------------------------------------

    CAT LLC estimates the budget for the consulting costs for Deloitte 
for the CAT Fee 2025-2 Period based on the current statement of work 
with Deloitte, which took into consideration past consulting costs, 
potential future consulting needs, the proposed rates and other 
contractual issues, as well as discussions with Deloitte. This process 
for estimating the budget for consulting costs for the CAT Fee 2025-2 
Period is the same process by which CAT LLC estimated the consulting 
costs for the Original 2025 CAT Budget. The Original 2025 CAT Budget 
estimated a budget for consulting services of $437,500 for the first 
quarter of 2025. The actual costs for consulting services for the first 
quarter of 2025, which are set forth in the Updated 2025 CAT Budget, 
were $450,745. Therefore, the variance between budgeted and actual 
consulting costs for the first quarter of 2025 was approximately 3%. 
Accordingly, CAT LLC believes that the process for estimating the 
budgeted consulting costs for the CAT Fee 2025-2 Period is reasonable.
(b) Changes From Prior Fee Filing
    Section 11.3(a)(iii)(B)(B) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to describe the reason for changes in 
the line item for consulting costs from the prior CAT Fee filing. 
Accordingly, this filing describes the changes in the consulting costs 
from the Original 2025 CAT Budget, which was used in the calculation of 
the prior Prospective CAT Fee, CAT Fee 2025-1.\78\ Specifically, the 
following describes the differences (if any) in the consulting costs as 
set forth in the Original 2025 CAT Budget versus the Updated 2025 CAT 
Budget for the full year of 2025 as well as for the third and fourth 
quarters of 2025, and the reasons for any changes.

    The annual 2025 budget for consulting costs as set forth in the 
Original 2025 CAT Budget was $1,750,000, and the annual 2025 budget for 
consulting costs as set forth in the Updated 2025 CAT Budget is 
approximately $1,750,000. Accordingly, the annual budget for consulting 
costs has not changed from the Original 2025 CAT Budget to the Updated 
2025 CAT Budget for the full year of 2025.
    Correspondingly, the budget for consulting costs for the third and 
fourth quarters of 2025 as set forth in the Original 2025 CAT Budget 
was $875,000,\79\ and the budget for consulting costs for the third and 
fourth quarters of 2025 as set forth in the Updated 2025 CAT Budget is 
$866,167.\80\ Accordingly, the budget for consulting costs for the 
third and fourth quarters of 2025 decreased by $8,833 (which is 
approximately 1%), from the Original 2025 CAT Budget to the Updated 
2025 CAT Budget. Therefore, the budget for consulting costs for the 
third and fourth quarters of 2025 remained nearly the same in the 
Original 2025 CAT Budget and the Updated 2025 CAT Budget.
---------------------------------------------------------------------------

    \79\ This calculation is $437,500 + $437,500 = $875,000.
    \80\ This calculation is $433,084 + $433,083 = $866,167.

(viii) Insurance Costs
(a) Description of Insurance Costs
    Section 11.3(a)(iii)(B)(B)(4) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to provide a brief description of the 
insurance costs set forth in the budget. The Operating Committee 
approved an operating budget for the CAT pursuant to Section 11.1(a) of 
the CAT NMS Plan that included $1,594,452 in insurance costs for the 
CAT Fee 2025-2 Period. The insurance costs represent the costs to be 
incurred for insurance for CAT during the CAT Fee 2025-2 Period.
    It is anticipated that the insurance costs for CAT during the CAT 
Fee 2025-2 Period will include costs related to cyber security 
liability insurance, directors' and officers' liability insurance, and 
errors and omissions liability insurance brokered by USI Insurance 
Services LLC (``USI''). Such policies are standard for corporate 
entities, and cyber security liability insurance is important for the 
CAT System. CAT LLC anticipates that it will continue to maintain this 
insurance during the CAT Fee 2025-2 Period, and notes that the annual 
premiums for these policies were competitive for the

[[Page 30382]]

coverage provided. CAT LLC estimated the budget for the insurance costs 
for the CAT Fee 2025-2 Period based on the insurance estimate from USI 
for 2025. The annual premiums would be paid by CAT LLC to USI.\81\
---------------------------------------------------------------------------

    \81\ Note that CAT LLC generally pays its USI insurance premiums 
once per year, and such payment is scheduled to occur during the 
third quarter of 2025.
---------------------------------------------------------------------------

    The budgeted insurance costs for the CAT Fee 2025-2 Period are 
based on an insurance cost estimate from USI for 2025. Accordingly, CAT 
LLC believes that the process for estimating the budgeted insurance 
costs for the CAT Fee 2025-2 Period is reasonable.
(b) Changes From Prior Fee Filing
    Section 11.3(a)(iii)(B)(B) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to describe the reason for changes in 
the line item for insurance costs from the prior CAT Fee filing. 
Accordingly, this filing describes the changes in the insurance costs 
from the Original 2025 CAT Budget, which was used in the calculation of 
the prior Prospective CAT Fee, CAT Fee 2025-1.\82\ Specifically, the 
following describes the differences (if any) in insurance costs as set 
forth in the Original 2025 CAT Budget versus the Updated 2025 CAT 
Budget for the full year of 2025 as well as for the third and fourth 
quarters of 2025, and the reasons for any changes.

    The annual 2025 budgeted insurance costs as set forth in the 
Original 2025 CAT Budget were $1,594,452, and the annual 2025 budgeted 
insurance costs as set forth in the Updated 2025 CAT Budget are 
$1,594,452. Accordingly, the annual budgeted insurance costs remained 
the same for the Original 2025 CAT Budget and the Updated 2025 CAT 
Budget for the full year of 2025.

fourth quarters of 2025 as set forth in the Updated 2025 CAT Budget are

(ix) Professional and Administration Costs
(a) Description of Professional and Administration Costs
    Section 11.3(a)(iii)(B)(B)(5) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to provide a brief description of the 
professional and administration costs set forth in the budget. The 
Operating Committee approved an operating budget for the CAT pursuant 
to Section 11.1(a) of the CAT NMS Plan that included $609,818 in

and made publicly available.\85\ The professional and administration 
costs would include costs related to accounting and accounting advisory 
services to support the operating and financial functions of CAT, 
financial statement audit services by an independent accounting firm, 
preparation of tax returns, and various cash management and treasury 
functions. The professional and administration costs represent the fees

    Financial Advisory Firm: Anchin. It is anticipated that the 
professional and administration costs for the CAT Fee 2025-2 Period

Anchin. CAT LLC anticipates that it will continue to employ Anchin 
during the CAT Fee 2025-2 Period based on, among other things, the 
firm's relevant expertise and fees, which are anticipated to remain in 
line with market rates for these financial advisory services. The fees 
for these services will be paid by CAT LLC to Anchin.
    It is anticipated that Anchin will provide a variety of services to 
the CAT during the CAT Fee 2025-2 Period, including the following:
     Update and maintain internal controls;

on historical costs adjusted for cost of living rate increases, and 
projected incremental advisory and support services.
    Accounting Firm: Grant Thornton. It is anticipated that the 
professional and administration costs for the CAT Fee 2025-2 Period 
will include costs related to accounting services performed by Grant 
Thornton. CAT LLC anticipates that it will continue to employ Grant 
Thornton during the CAT Fee 2025-2 Period based on, among other things, 
the firm's relevant expertise and fees, which are anticipated to remain 
in line with market rates for these financial advisory services. It is 
anticipated that Grant Thornton will continue to be engaged as an 
independent accounting firm to complete the audit of CAT LLC's 
financial statements, in accordance with the requirements of the CAT 
NMS Plan. The fees for these services will be paid by CAT LLC to Grant 
Thornton. CAT

for the CAT Fee 2025-2 Period based on the anticipated hourly rates and 
the anticipated services plus an administrative fee.
    Professional and Administration Cost Estimates. CAT LLC estimates 
that the budget for professional and administration services during the 
CAT Fee 2025-2 Period will be approximately $609,818. The budget for 
professional and administration services during the CAT Fee 2025-2 
Period is based on the Updated 2025 CAT Budget. CAT LLC estimated the 
budget for the professional and administration costs for the CAT Fee 
2025-2 Period based on a review of past professional and administration 
costs, potential future professional and administration needs, the 
proposed rates and other contractual issues, as well as discussions 
with Anchin and Grant Thornton. This process for estimating the budget 
for the professional and administration costs for the CAT Fee 2025-2 
Period is the same process by which CAT LLC estimated the professional 
and administration costs for the Original 2025 CAT Budget. The Original 
2025 CAT Budget estimated a budget for professional and administration 
costs of $168,750 for the first quarter of 2025. The actual costs for 
professional and administration services for the first quarter of 2025, 
which are set forth in the Updated 2025 Budget, were $297,513. The 
increase of $128,763 was due to unanticipated issues that required 
additional professional and administration efforts on behalf of CAT LLC 
that developed after the budget was created. Such additional costs were 
primarily due to increases in both financial advisory costs and 
accounting costs as a result of incremental controls and procedures 
relating to billings and collections of fees from Participants and 
Industry Members and the corresponding repayments of promissory notes 
on historical costs as well as incremental subsequent events procedures 
relating to the 2023 audit for CAT LLC. Accordingly, CAT LLC believes 
that the process for estimating the budgeted professional and 
administration costs for the CAT Fee 2025-2 Period is reasonable.
(b) Changes From Prior Fee Filing

set forth in the Original 2025 CAT Budget versus the Updated 2025 CAT 
Budget for the full year of 2025 as well as for the third and fourth 
quarters of 2025, and the reasons for any changes.
---------------------------------------------------------------------------

    \86\ See Fee Filing for CAT Fee 2025-1.
---------------------------------------------------------------------------

    The annual 2025 budgeted professional and administration costs as 
set forth in the Original 2025 CAT Budget were $882,456, and the annual 
2025 budgeted professional and administration costs as set forth in the 
Updated 2025 CAT Budget are $1,193,090. Accordingly, the budgeted 
annual costs for professional and administration services increased by 
$310,634 from the Original 2025 CAT Budget to the Updated 2025 CAT 
Budget for the full year of 2025.
    Correspondingly, the budgeted costs for professional and 
administration services for the third and fourth quarters of 2025 as 
set forth in the Original 2025 CAT Budget were $444,246,\87\ and the 
budgeted costs for professional and administration services services 
[sic] for the third and fourth quarters of 2025 as set forth in the 
Updated 2025 CAT Budget are $609,818.\88\ Accordingly, the budgeted 
costs for professional and administration services for the third and 
fourth quarters of 2025 increased by $165,572 from the Original 2025 
CAT Budget to the Updated 2025 CAT Budget for the third and fourth 
quarters of 2025.
---------------------------------------------------------------------------

    \87\ This calculation is $168,750 + $275,496 = $444,246.
    \88\ This calculation is $414,818 + $195,000 = $609,818.
---------------------------------------------------------------------------

    This budgeted increase in the professional and administration costs 
in the Updated 2025 CAT Budget from the Original 2025 Budget, both for 
the full year for 2025 and for the third and fourth quarters of 2025, 
was primarily due to increases in both financial advisory costs and 
accounting costs as a result of additional anticipated efforts related 
to billings and collections of fees from Participants and Industry 
Members, coupled with expected incremental efforts related to 
supporting CAT LLC's independent auditors for the 2024 audit.
(x) Public Relations Costs
(a) Description of Public Relations Costs
    Section 11.3(a)(iii)(B)(B)(6) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to provide a brief description of the 
public relations costs set forth in the budget. The Operating Committee 
approved an operating budget for the CAT pursuant to Section 11.1(a) of 
the CAT NMS Plan that included $0 in public relations costs for the CAT 
Fee 2025-2 Period. The public relations costs represent the fees paid 
to a public relations firm for professional communications services to 
CAT, including media relations consulting, strategy and execution. 
Because CAT LLC anticipates that it will not engage a public relations 
firm for the third and fourth quarters of 2025, the budget for public 
relations costs for this period is $0.
(b) Changes From Prior Fee Filing
    Section 11.3(a)(iii)(B)(B) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to describe the reason for changes in 
the line item for public relations costs from the prior CAT Fee filing. 
Accordingly, this filing describes the changes in the public relations 
costs from the Updated 2025 CAT Budget, which was used in the 
calculation of the prior Prospective CAT Fee, CAT Fee 2025-1.\89\ 
Specifically, the following describes the differences (if any) in the 
public relations costs as set forth in the Original 2025 CAT Budget 
versus the Updated 2025 CAT Budget for the full year of 2025 as well as 
for the third and fourth quarters of 2025, and the reasons for any 
changes.
---------------------------------------------------------------------------

    \89\ See Fee Filing for CAT Fee 2025-1.
---------------------------------------------------------------------------

    The annual budgeted public relations costs for 2025 as set forth in 
the Original 2025 CAT Budget were $50,000, and the annual budgeted 
public relations costs for 2025 as set forth in the Updated 2025 CAT 
Budget are $6,575. Accordingly, the annual budget for public relations 
cost for 2025 decreased by $43,425 from the Original 2025 CAT Budget to 
the Updated 2025 CAT Budget for the full year of 2025.
    Correspondingly, the budgeted costs for public relations services 
for the third and fourth quarters of 2025 as set forth in the Original 
2025 CAT Budget were $25,000,\90\ and the budgeted costs for public 
relations services for the third and fourth quarters of 2025 as set 
forth in the Updated 2025 CAT Budget are $0.\91\ Accordingly, the 
budgeted costs for public relations services for the third and fourth 
quarters of 2025 decreased by $25,000 from the Original 2025 CAT Budget 
to the Updated 2025 CAT Budget for the third and fourth quarters of 
2025.
---------------------------------------------------------------------------

    \90\ This calculation is $12,500 + $12,500 = $25,000.
    \91\ This calculation is $0 + $0 = $0.

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

[[Page 30384]]

    This budgeted decrease in the public relations costs from the 
Original 2025 CAT Budget to the Updated 2025 CAT Budget, both for the 
full year for 2025 and for the third and fourth quarters of 2025, was 
primarily due to CAT LLC's anticipation that it would not engage a 
public relations firm for the remainder of 2025.
(xi) Reserve
(a) Description of Reserve
    Section 11.3(a)(iii)(B)(B) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to provide a brief description of the 
reserve costs set forth in the budget. The Operating Committee approved 
an operating budget for the CAT pursuant to Section 11.1(a) of the CAT 
NMS Plan that includes a reserve amount for 2025. Section 11.1(a)(i) of 
the CAT NMS Plan states that the budget shall include a reserve. 
Section 11.1(a)(ii) of the CAT NMS Plan further describes the reserve 
as follows:
    For 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. To the 
extent collected CAT fees exceed CAT costs, including the reserve of 
25% of the annual budget, such surplus shall be used to offset future 
fees. For 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). For the avoidance of doubt, the calculation of 
the amount of the reserve would exclude the amount of the reserve from 
the budget.
    CAT LLC determined to maintain a reserve in the amount of 25% of 
the total expenses set forth in Updated 2025 CAT Budget (which does not 
include the reserve amount). Accordingly, the total 25% reserve was 
calculated by multiplying the total expenses set forth in the Updated 
2025 CAT Budget (other than the reserve) by 25%, which is 
$57,083,638.\92\
---------------------------------------------------------------------------

    \92\ The reserve was calculated by multiplying $228,334,551 by 
25%, which equals approximately $57,083,638.
---------------------------------------------------------------------------

    The Updated 2025 CAT Budget states that CAT LLC had accrued 
$70,942,596 for the reserve as of the beginning of 2025, and an 
additional $28,846,075 during the first quarter of 2025, from the 
collection of CAT Fees 2024-1 and 2025-1 and the related Participant 
CAT Fees. In addition, the Updated 2025 CAT Budget anticipates the 
collection of an additional $11,821,477 during the second quarter of 
2025 via CAT Fee 2025-1 and the related Participant CAT Fee. 
Accordingly, the Updated 2025 CAT Budget estimates that CAT LLC would 
collect a surplus reserve amount through June 2025 of $54,526,412 over 
the 25% reserve amount of $57,083,638.\93\ The following chart 
summarizes the calculation of the surplus reserve amount included in 
Budgeted CAT Costs 2025-2 and used to calculate CAT Fee 2025-2:
---------------------------------------------------------------------------

    \93\ This calculation is ($70,942,596 + $28,846,075 + 
$11,821,477)-$57,083,638 = $54,526,412.

------------------------------------------------------------------------
 
------------------------------------------------------------------------
1. Total reserve as of the beginning of 2025............     $70,942,596
2. Total reserve collected during the Q1 2025...........      28,846,075
3. Total reserve estimated for Q2 2025..................      11,821,477
                                                         ---------------
    4. TOTAL RESERVE COLLECTED or ESTIMATED TO BE            111,610,148
     COLLECTED by END of Q2 of 2025 (Row 1 + Row 2 + Row
     3).................................................
5. Budgeted 2025 Reserve (Total 2025 CAT costs other          57,083,638
 than reserve ($228,334,551) multiplied by 25%).........
                                                         ---------------
    TOTAL SURPLUS RESERVE (Row 4-Row 5).................      54,526,412
------------------------------------------------------------------------

    Such surplus was related, in part, to (i) the collection of CAT 
fees in excess of the budgeted CAT costs for 2024 and 2025 in light of 
the greater actual executed equivalent share volume than the projected 
executed equivalent share volume for CAT Fees 2024-1 and 2025-1, and 
(ii) a reduction in anticipated budgeted costs associated with the 
implementation of certain cost savings measures approved by the SEC 
pertaining to the processing of options market maker quotes and the 
storage of certain data.\94\
---------------------------------------------------------------------------

    \94\ See Cost Savings Amendment.
---------------------------------------------------------------------------

    As set forth in the Budgeted CAT Costs 2025-2, the surplus reserve 
balance of $54,526,412 would be used to offset a portion of CAT costs 
for the third and fourth quarters of 2025, thereby reducing the fee 
rate to be paid for CAT Fee 2025-2. Specifically, the total costs used 
to calculate the fee rate for CAT Fee 2025-2 would be reduced by the 
amount of the surplus reserve as set forth in the following table:

------------------------------------------------------------------------
 
------------------------------------------------------------------------
1. Total Budgeted CAT Costs 2025-2 Other than Reserve       $115,252,921
 (i.e., costs for Q3 and Q4 of 2025)....................
2. Surplus Reserve......................................    (54,526,510)
                                                         ---------------
    3. Total Budgeted CAT Costs 2025-2 (Row 1-Row 2)....      60,726,412
------------------------------------------------------------------------

    Accordingly, the fee rate for CAT Fee 2025-2 is calculated based on 
this reduced amount of $60,726,412, resulting in a fee rate of 
$0.000009 per executed equivalent share. If the fee rate for CAT Fee 
2025-2 were calculated solely based on the reasonably budgeted costs 
for CAT for July-December 2025 excluding the reduction in that amount 
due to the surplus reserve offset (that is, based on $115,252,921, not 
$60,726,412), the fee rate would be the higher rate of $0.000017.\95\
---------------------------------------------------------------------------

    \95\ See CAT Fee Alert 2025-2 (5/29/25).
---------------------------------------------------------------------------

(b) Changes From Prior Fee Filing
    Section 11.3(a)(iii)(B)(B) of the CAT NMS Plan requires the fee 
filing for a Prospective CAT Fee to describe the reason for changes in 
the line item for a reserve from the prior CAT Fee filing. Accordingly, 
this filing describes the changes in the reserve from the Original 2025 
CAT Budget, which was used in the calculation of the prior Prospective 
CAT Fee, CAT Fee 2025-1.\96\
---------------------------------------------------------------------------

    \96\ See Fee Filing for CAT Fee 2025-1.
---------------------------------------------------------------------------

    For the Original 2025 CAT Budget, CAT LLC determined to maintain a 
reserve in the amount of 25% of budgeted CAT costs (other than the 
reserve). Accordingly, the total 25% reserve was calculated by 
multiplying the budgeted CAT costs (other than the reserve) as set 
forth in the Original 2025 CAT Budget (which is $248,846,076) by 25%, 
for a target reserve amount of

[[Page 30385]]

$62,211,519. However, the Original 2025 CAT Budget recognized that a 
portion of the reserve--$38,369,315--would have been previously 
collected, and therefore would not need to be included the budgeted CAT 
costs to be recovered by the CAT Fees. Specifically, the Original 2025 
CAT Budget recognized that there was (i) a liquidity reserve balance of 
$27,695,385 at the beginning of 2025, (ii) a favorable variance of 
$10,084,698 for budgeted versus actual cloud hosting services costs 
covering the period from July 16, 2024 through September 30, 2024, and 
(iii) a Participation Fee from a new Participant in the CAT NMS Plan of 
$589,232. These three items totaled $38,369,315. Accordingly, the 
Original 2025 CAT Budget only included $23,842,200 to be collected 
towards the reserve via the CAT Fee. This $23,842,200 is calculated by 
reducing the total 25% reserve amount of $62,211,519 by the $38,369,315 
previously collected for the reserve. In the Original 2025 CAT Budget, 
the budget anticipated collecting the remaining reserve amount of 
$23,842,200 evenly throughout the year, that is, $5,960,500 for each 
quarter.
    As discussed above, CAT LLC determined to maintain a reserve in the 
amount of 25% of the budgeted CAT costs (other than the reserve). 
Accordingly, the total 25% reserve was calculated by multiplying the 
budgeted CAT costs (other than the reserve) as set forth in the Updated 
2025 CAT Budget (which is $228,334,551) by 25%, for a target reserve 
amount of $57,083,638.\97\ However, the Updated 2025 CAT Budget states 
that CAT LLC had accrued $70,942,596 for the reserve as of the 
beginning of 2025, and an additional $28,846,075 during the first 
quarter of 2025, from the collection of CAT Fees 2024-1 and 2025-1 and 
the related Participant CAT Fees. In addition, the Updated 2025 CAT 
Budget anticipates the collection of an additional $11,821,477 during 
the second quarter of 2025 via CAT Fee 2025-1 and the related 
Participant CAT Fee. Accordingly, the Updated 2025 CAT Budget estimates 
that CAT LLC would collect a surplus reserve amount through June 2025 
of $54,526,412 in excess of the 25% targeted reserve amount of 
$57,083,638.\98\ Accordingly, the Updated 2025 CAT Budget anticipates 
reducing the recoverable CAT costs by $54,526,412 in the second half of 
2025, specifically a reduction of $27,263,255 in each of the third and 
fourth quarters of 2025.
---------------------------------------------------------------------------

    \97\ The reserve was calculated by multiplying $228,334,551 by 
25%, which equals approximately $57,083,638.
    \98\ This calculation is ($70,942,596 + $28,846,075 + 
$11,821,477)-$57,083,638 = $54,526,412.
---------------------------------------------------------------------------

    As discussed above, such surplus reserve balance of $54,526,412 
would be used to offset a portion of CAT costs for the third and fourth 
quarters of 2025, thereby reducing the fee rate for CAT Fee 2025-2 in 
accordance with Section 11.1(a)(ii) of the CAT NMS Plan. Section 
11.1(a)(ii) of the CAT NMS Plan states that ``[t]o the extent collected 
CAT fees exceed CAT costs, including the reserve of 25% of the annual 
budget, such surplus shall be used to offset future fees.''
(D) Projected Total Executed Equivalent Share Volume
    The calculation of Fee Rate 2025-2 also requires the determination 
of the projected total executed equivalent share volume of transactions 
in Eligible Securities for the CAT Fee 2025-2 Period. Under the CAT NMS 
Plan, the Operating Committee is required to ``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.'' \99\ The Operating Committee is required to 
base its projection on the prior twelve months, but it may use its 
discretion to analyze the likely volume for the upcoming year. Such 
discretion would allow the Operating Committee to use its judgment when 
estimating projected total executed equivalent share volume if the 
volume over the prior twelve months was unusual or otherwise unfit to 
serve as the basis of a future volume estimate.\100\
---------------------------------------------------------------------------

    \99\ Section 11.3(a)(i)(D) of the CAT NMS Plan.
    \100\ CAT Funding Model Approval Order at 62651.
---------------------------------------------------------------------------

    The total executed equivalent share volume of transactions in 
Eligible Securities for the 12-month period from April 2024 through 
March 2025 was 4,580,287,680,646.28 executed equivalent shares. The 
Operating Committee has determined to calculate the projected total 
executed equivalent share volume for the six-month recovery period for 
CAT Fee 2025-2 by multiplying by one-half the executed equivalent share 
volume for the 12-month period from April 2024 through March 2025. The 
Operating Committee determined that such an approach was reasonable as 
the CAT's annual executed equivalent share volume has remained 
relatively constant. For example, the executed equivalent share volume 
for 2021 was 3,963,697,612,395, the executed equivalent share volume 
for 2022 was 4,039,821,841,560.31, the executed equivalent share volume 
for 2023 was 3,868,940,345,680.6, and the executed equivalent share 
volume for 2024 was 4,295,884,600,069.41. Accordingly, the projected 
total executed equivalent share volume for the six-month period for CAT 
Fee 2025-2 is projected to be 2,290,143,840,323.14 executed equivalent 
shares.\101\
---------------------------------------------------------------------------

    \101\ This projection was calculated by multiplying 
4,580,287,680,646.28 executed equivalent shares by one-half.
---------------------------------------------------------------------------

    The projected total executed equivalent share volume of all 
transactions in Eligible Securities for the six-month recovery period 
for CAT Fee 2025-2 and a description of the calculation of the 
projection is provided in this filing in accordance with the 
requirement in the CAT NMS Plan to provide such information in a fee 
filing for a CAT Fee.\102\
---------------------------------------------------------------------------

    \102\ Section 11.3(a)(iii)(B) of the CAT NMS Plan.
---------------------------------------------------------------------------

(E) Fee Rate 2025-2
    Fee Rate 2025-2 would be calculated by dividing the Budgeted CAT 
Costs 2025-2 by the reasonably projected total executed equivalent 
share volume of all transactions in Eligible Securities for the six-
month recovery period for CAT Fee 2025-2, as described in detail 
above.\103\ Specifically, Fee Rate 2025-2 would be calculated by 
dividing $60,726,412 by 2,290,143,840,323.14 executed equivalent 
shares. As a result, Fee Rate 2025-2 would be $0.00002651641828376661 
per executed equivalent share. Fee Rate 2025-2 is provided in this 
filing in accordance with the requirement in the CAT NMS Plan to 
provide the Fee Rate in a fee filing for a CAT Fee.\104\
---------------------------------------------------------------------------

    \103\ In approving the CAT Funding Model, the Commission stated 
that ``[t]he manner in which the Fee Rate for Prospective CAT Costs 
will be calculated (i.e., by dividing the CAT costs reasonably 
budgeted for the upcoming year by the reasonably projected total 
executed equivalent share volume of all transactions in Eligible 
Securities for the year) is reasonable.'' CAT Funding Model Approval 
Order at 62651.
    \104\ See Section 11.3(a)(iii)(B)(A) of the CAT NMS Plan.
---------------------------------------------------------------------------

(3) Monthly Fees
    CEBBs and CEBSs would be required to pay fees for CAT Fee 2025-2 on 
a monthly basis for six months, from August 2025 until January 2026. A 
CEBB's or CEBS's fee for each month would be calculated based on the 
transactions in Eligible Securities executed by the CEBB or CEBS from 
the prior month.\105\ Proposed paragraph (a)(5)(A) of the fee schedule 
would state that each CAT Executing Broker would receive its first 
invoice for CAT Fee

[[Page 30386]]

2025-2 in August 2025, and would receive an invoice for CAT Fee 2025-2 
each month thereafter until January 2026. Proposed paragraph (a)(5)(B) 
of the fee schedule would state that ``Consolidated Audited Trail, LLC 
shall provide each CAT Executing Broker with an invoice for CAT Fee 
2025-2 on a monthly basis.'' In addition, paragraph (b)(1) of the fee 
schedule states that each CEBB and CEBS is required to pay its CAT fees 
``each month.''
---------------------------------------------------------------------------

    \105\ See proposed paragraph (a)(5)(B) of the fee schedule.
---------------------------------------------------------------------------

(4) Consolidated Audit Trail Funding Fees
    To implement CAT Fee 2025-2, the Exchange proposes to add a new 
paragraph to the ``Consolidated Audit Trail Funding Fees'' section of 
the Exchange's fee schedule, to include the proposed paragraphs 
described below.
(A) Fee Schedule for CAT Fee 2025-2
    The CAT NMS Plan states that:

    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.\106\
---------------------------------------------------------------------------

    \106\ Section 11.3(a)(iii)(A) of the CAT NMS Plan.

    Accordingly, based on the factors discussed above, the Exchange 
proposes to add paragraph (a)(5) to the Consolidated Audit Trail 
Funding Fees section of its fee schedule. Proposed paragraph (a)(5) 
would state the following:
    (A) Each CAT Executing Broker shall receive its first invoice for 
CAT Fee 2025-2 in August 2025, which shall set forth the CAT Fee 2025-2 
fees calculated based on transactions in July 2025, and shall receive 
an invoice for CAT Fee 2025-2 for each month thereafter until January 
2026.
    (B) Consolidated Audit Trail, LLC shall provide each CAT Executing 
Broker with an invoice for CAT Fee 2025-2 on a monthly basis. Each 
month, such invoices shall set forth a fee for each transaction in 
Eligible Securities executed by the CAT Executing Broker in its 
capacity as a CAT Executing Broker for the Buyer (``CEBB'') and/or the 
CAT Executing Broker for the Seller (``CEBS'') (as applicable) from the 
prior month as set forth in CAT Data. The fee for each such transaction 
will be calculated by multiplying the number of executed equivalent 
shares in the transaction by the fee rate of $0.000009 per executed 
equivalent share.
    (C) Notwithstanding the last invoice date of January 2026 for CAT 
Fee 2025-2 in paragraph 5(A), CAT Fee 2025-2 shall continue in effect 
after January 2026, with each CAT Executing Broker receiving an invoice 
for CAT Fee 2025-2 each month, until a new subsequent CAT Fee is in 
effect with regard to Industry Members in accordance with Section 19(b) 
of the Exchange Act. Consolidated Audit Trail, LLC will provide notice 
when CAT Fee 2025-2 will no longer be in effect.
    (D) Each CAT Executing Broker shall be required to pay each invoice 
for CAT Fee 2025-2 in accordance with paragraph (b).
    As noted in the Plan amendment for the CAT Funding Model, ``[a]s 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.'' \107\ Accordingly, proposed paragraph (a)(5)(B) 
of the fee schedule would set forth a fee rate of $0.000009 per 
executed equivalent share. This fee rate is calculated by multiplying 
Fee Rate 2025-2 of $0.00002651641828376661 by one-third, and rounding 
the result to six decimal places.\108\ The Operating Committee 
determined to use six decimal places to balance the accuracy of the 
calculation with the potential systems and other impracticalities of 
using additional decimal places in the calculation.
---------------------------------------------------------------------------

    \107\ CAT Funding Model Approval Order at 62658, n.658.
    \108\ Dividing $0.00002651641828376661 by three equals 
$0.000008838806094588872. Rounding $0.000008838806094588872 to six 
decimal places equals $0.000009.
---------------------------------------------------------------------------

    The proposed language in paragraph (a)(5)(A) of the fee schedule 
would describe when CAT Executing Brokers would receive their first 
monthly invoice for CAT Fee 2025-2. Specifically, CAT Executing Brokers 
would receive their first monthly invoice for CAT Fee 2025-2 in August 
2025 and the fees set forth in that invoice would be calculated based 
on transactions executed in July 2025. The payment for the first 
invoice would be required within 30 days after the receipt of the first 
invoice (unless a longer period is indicated), as described in 
paragraph (b)(2) of the fee schedule.
    Proposed paragraph (a)(5)(A) of the fee schedule also would 
describe the monthly cadence of the invoices for CAT Fee 2025-2. 
Specifically, after the first invoices are provided to CAT Executing 
Brokers in August 2025, invoices will be sent to CAT Executing Brokers 
each month thereafter until January 2026.
    Proposed paragraph (a)(5)(B) of the fee schedule would describe the 
invoices for CAT Fee 2025-2. Proposed paragraph (a)(5)(B) of the fee 
schedule would state that ``Consolidated Audit Trail, LLC shall provide 
each CAT Executing Broker with an invoice for CAT Fee 2025-2 on a 
monthly basis.'' Proposed paragraph (a)(5)(B) of the fee schedule also 
would describe the fees to be set forth in the invoices for CAT Fee 
2025-2. Specifically, it would state that ``[e]ach month, such invoices 
shall set forth a fee for each transaction in Eligible Securities 
executed by the CAT Executing Broker in its capacity as a CAT Executing 
Broker for the Buyer (`CEBB') and/or the CAT Executing Broker for the 
Seller (`CEBS') (as applicable) from the prior month as set forth in 
CAT Data. The fee for each such transaction will be calculated by 
multiplying the number of executed equivalent shares in the transaction 
by the fee rate of $0.000009 per executed equivalent share.''
    Since CAT Fee 2025-2 is a monthly fee based on actual transaction 
volume from the prior month, CAT Fee 2025-2 may collect more or less 
than two-thirds of the Budgeted CAT Costs 2025-2. To the extent that 
CAT Fee 2025-2 collects more than two-thirds of the Budgeted CAT Costs 
2025-2, any excess money collected will be used to offset future fees 
and/or to fund the reserve for the CAT. To the extent that CAT Fee 
2025-2 collects less than two-thirds of the Budgeted CAT Costs 2025-2, 
the budget for the CAT in the ensuing months will reflect such 
shortfall.
    Furthermore, proposed paragraph (a)(5)(C) of the fee schedule would 
describe how long CAT Fee 2025-2 would remain in effect. It would state 
that ``[n]otwithstanding the last invoice date of January 2026 for CAT 
Fee 2025-2 in paragraph 5(A), CAT Fee 2025-2 shall continue in effect 
after January 2026, with each CAT Executing Broker receiving an invoice 
for CAT Fee 2025-2 each month, until a new subsequent CAT Fee is in 
effect with regard to Industry Members in accordance with Section 19(b) 
of the Exchange Act. Consolidated Audit Trail, LLC will provide notice 
when CAT Fee 2025-2 will no longer be in effect.''
    Finally, proposed paragraph (a)(5)(D) of the fee schedule would set 
forth the

[[Page 30387]]

requirement for the CAT Executing Brokers to pay the invoices for CAT 
Fee 2025-2. It would state that ``[e]ach CAT Executing Broker shall be 
required to pay each invoice for CAT Fee 2025-2 in accordance with 
paragraph (b).''
(B) Manner of Payment
    Paragraph (b)(1) of the ``Consolidated Audit Trail Funding Fees'' 
section of the fee schedule describes the manner of payment of Industry 
Member CAT fees. It states that ``[e]ach CAT Executing Broker shall pay 
its CAT fees as required pursuant to paragraph (a) each month to the 
Consolidated Audit Trail, LLC in the manner prescribed by the 
Consolidated Audit Trail, LLC.'' The CAT NMS Plan requires the 
Operating Committee to establish a system for the collection of CAT 
fees.\109\ The Plan Processor has established a billing system for CAT 
fees.\110\ Accordingly, CAT Executing Brokers would be required to pay 
CAT Fee 2025-2 in accordance with such system.
---------------------------------------------------------------------------

    \109\ Section 11.4 of the CAT NMS Plan.
    \110\ The billing process and system are described in CAT Alert 
2023-02 as well as the CAT FAQs related to the billing of CAT fees, 
the Industry Member CAT Reporter Portal User Guide, the FCAT 
Industry Member Onboarding Guide, the FCAT Connectivity Supplement 
for Industry Members and the CAT Billing Webinars (dated Sept. 28, 
2023 and Nov. 7, 2023), each available on the CAT website.
---------------------------------------------------------------------------

(C) Failure To Pay CAT Fees
    The CAT NMS Plan further 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). 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.\111\
---------------------------------------------------------------------------

    \111\ Section 11.4 of the CAT NMS Plan.

---------------------------------------------------------------------------
    Paragraph (b)(2) of the fee schedule states that:

    Each CAT Executing Broker shall pay the CAT fees required 
pursuant to paragraph (a) within thirty days after receipt of an 
invoice or other notice indicating payment is due (unless a longer 
payment period is otherwise indicated). If a CAT Executing Broker 
fails to pay any such CAT fee when due, such CAT Executing Broker 
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 
(i) the Prime Rate plus 300 basis points, or (ii) the maximum rate 
permitted by applicable law.

    The requirements of paragraph (b)(2) would apply to CAT Fee 2025-2.
(5) CAT Fee Details
    The CAT NMS Plan states that:

    Details regarding the calculation of a Participant or CAT 
Executing Broker's 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.\112\
---------------------------------------------------------------------------

    \112\ Section 11.3(a)(iv)(A) of the CAT NMS Plan.

    Such information would provide CEBBs and CEBSs with the ability to 
understand the details regarding the calculation of their CAT Fee.\113\ 
CAT LLC will provide CAT Executing Brokers with these details regarding 
the calculation of their CAT Fees on their monthly invoice for the CAT 
Fees.
---------------------------------------------------------------------------

    \113\ In approving the CAT Funding Model, the Commission stated 
that, ``[i]n the Commission's view, providing CAT Execut[ing] 
Brokers information regarding the calculation of their CAT Fees will 
aid in transparency and permit CAT Execut[ing] Brokers to confirm 
the accuracy of their invoices for CAT Fees.'' CAT Funding Model 
Approval Order at 62667.
---------------------------------------------------------------------------

    In addition, CAT LLC will make certain aggregate statistics 
regarding CAT Fees publicly available. Specifically, the CAT NMS Plan 
states 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.'' \114\ Such aggregate 
statistics will be available on the CAT website.
---------------------------------------------------------------------------

    \114\ Section 11.3(a)(iv)(B) of the CAT NMS Plan. In approving 
the CAT Funding Model, the Commission stated that ``[t]he 
publication of the aggregate executed equivalent share volume and 
aggregate fee is appropriate because it would allow Participants and 
CAT Executing Brokers a high-level validation of executed volume and 
fees.'' CAT Funding Model Approval Order at 62667.
---------------------------------------------------------------------------

    Furthermore, CAT LLC will make publicly available on the CAT 
website the total amount invoiced each month that CAT Fee 2025-2 is in 
effect as well as the total amount invoiced for CAT Fee 2025-2 for all 
months since its commencement. CAT LLC also will make publicly 
available on the CAT website the total costs to be collected from 
Industry Members for CAT Fee 2025-2.
(6) Financial Accountability Milestones
    The CAT NMS Plan states 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.'' \115\ Under Section 1.1 of the CAT NMS Plan, a 
Financial Accountability Milestone is considered complete as of the 
date identified in the Participants' Quarterly Progress Reports. As 
indicated by the Participants' Quarterly Progress Report for the second 
and third quarter of 2024,\116\ the Financial Accountability Milestone 
related to Period 4 was satisfied on July 15, 2024. In addition, the 
satisfaction of the Financial Accountability Milestone related to 
Period 4 was described in detail in the fee filing for the first 
Prospective CAT Fee, CAT Fee 2024-1.\117\

Filing for CAT Fee 2024-1'').
---------------------------------------------------------------------------

(7) Relationship to CAT Fee 2025-1
    CAT LLC intends for CAT Fee 2025-2 to replace CAT Fee 2025-1 (which 
has a fee rate of $0.000022).\118\ Accordingly, as long as CAT Fee 
2025-2 is in effect, CAT Fee 2025-1 would not be charged to CEBBs, 
CEBSs and Participants. Specifically, subject to CAT Fee 2025-2 being 
in effect, CAT LLC intends to send the last invoice for CAT Fee 2025-1 
in July 2025 based on June 2025 transactions and, correspondingly, to 
send the first invoice for CAT Fee 2025-2 in August 2025 based on July 
2025 transactions.
---------------------------------------------------------------------------

    \118\ Note that CAT Fee 2025-2 is separate from and will be in 
addition to any Historical CAT Assessment to Industry Members.
---------------------------------------------------------------------------

(8) Participant Invoices
    While CAT Fees charged to Industry Members become effective in 
accordance with the requirements of Section 19(b) of the Exchange 
Act,\119\ 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.\120\ On May 28, 2025, the 
Operating Committee approved the Participant fee related to CAT Fee 
2025-2. Specifically, pursuant to the requirements of CAT NMS 
Plan,\121\ each

[[Page 30388]]

Participant would be required to pay a CAT fee calculated using the fee 
rate of $0.000009 per executed equivalent share, which is the same fee 
rate that applies to CEBBs and CEBSs. Like CEBBs and CEBSs, each 
Participant would be required to pay such CAT fees on a monthly basis 
for six months, from September 2025 until February 2026, and each 
Participant's fee for each month would be calculated based on the 
transactions in Eligible Securities executed on the applicable exchange 
(for the Participant exchanges) or otherwise than on an exchange (for 
FINRA) in the prior month. Accordingly, each Participant will receive 
its first invoice in August 2025, and would receive an invoice each 
month thereafter until January 2026. Like with the CAT Fee 2025-2 
applicable to CEBBs and CEBSs as described in proposed paragraph 
(a)(5)(C) of the fee schedule, notwithstanding the last invoice date of 
January 2026, Participants will continue to receive invoices for this 
fee each month until a new subsequent CAT Fee is in effect with regard 
to Industry Members. Furthermore, Section 11.4 of the CAT NMS Plan 
states that each Participant is required to pay such invoices as 
required by Section 3.7(b) of the CAT NMS Plan. Section 3.7(b) states, 
in part, that
---------------------------------------------------------------------------

    \119\ Section 11.3(a)(i)(A)(I) of the CAT NMS Plan.
    \120\ CAT Funding Model Approval Order at 62659.
    \121\ See Section 11.3(a)(ii) and Appendix B of the CAT NMS 
Plan.

[e]ach 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) Prime Rate plus 300 basis 
points; or (ii) the maximum rate permitted by applicable law.
2. Statutory Basis
    The Exchange believes the proposed rule change is consistent with 
the requirements of the Exchange Act. The Exchange believes that the 
proposed rule change is consistent with Section 6(b)(5) of the 
Act,\122\ which requires, among other things, that the Exchange's rules 
must be designed to prevent fraudulent and manipulative acts and 
practices, to promote just and equitable principles of trade, and, in 
general, to protect investors and the public interest, and not designed 
to permit unfair discrimination between customers, issuers, brokers and 
dealers. The Exchange also believes that the proposed rule change is 
consistent with the provisions of Section 6(b)(4) of the Act,\123\ 
because it provides for the equitable allocation of reasonable dues, 
fees and other charges among members and issuers and other persons 
using its facilities. The Exchange further believes that the proposed 
rule change is consistent with Section 6(b)(8) of the Act,\124\ which 
requires that the Exchange's rules not impose any burden on competition 
that is not necessary or appropriate in furtherance of the purpose of 
the Exchange Act. These provisions also require that the Exchange be 
``so organized and [have] the capacity to be able to carry out the 
purposes'' of the Act and ``to comply, and . . . to enforce compliance 
by its members and persons associated with its members,'' with the 
provisions of the Exchange Act.\125\ Accordingly, a reasonable reading 
of the Act indicates that it intended that regulatory funding be 
sufficient to permit an exchange to fulfill its statutory 
responsibility under the Act, and contemplated that such funding would 
be achieved through equitable assessments on the members, issuers, and 
other users of an exchange's facilities.

    \125\ See 15 U.S.C. 78f(b)(1).
---------------------------------------------------------------------------

    The Exchange believes that this proposal is consistent with the Act 
because it implements provisions of the Plan and is designed to assist 
the Exchange in meeting regulatory obligations pursuant to the Plan. In 
approving the Plan, the SEC noted that the Plan ``is necessary and 
appropriate in the public interest, for the protection of investors and 
the maintenance of fair and orderly markets, to remove impediments to, 
and perfect the mechanism of a national market system, or is otherwise 
in furtherance of the purposes of the Act.'' \126\ To the extent that 
this proposal implements the Plan and applies specific requirements to 
Industry Members, the Exchange believes that this proposal furthers the 
objectives of the Plan, as identified by the SEC, and is therefore 
consistent with the Act.
---------------------------------------------------------------------------

    \126\ CAT NMS Plan Approval Order at 84697.
---------------------------------------------------------------------------

    The Exchange believes that the proposed fees to be paid by the 
CEBBs and CEBSs are reasonable, equitably allocated and not unfairly 
discriminatory. First, the CAT Fee 2025-2 fees to be collected are 
directly associated with the budgeted costs of establishing and 
maintaining the CAT, where such costs include Plan Processor costs and 
costs related to technology, legal, consulting, insurance, professional 
and administration, and public relations costs.
    The proposed CAT Fee 2025-2 fees would be charged to Industry 
Members in support of the maintenance of a consolidated audit trail for 
regulatory purposes. The proposed fees, therefore, are consistent with 
the Commission's view that regulatory fees be used for regulatory 
purposes and not to support the Exchange's business operations. The 
proposed fees would not cover Exchange services unrelated to the CAT. 
In addition, any surplus would be used as a reserve to offset future 
fees. Given the direct relationship between CAT fees and CAT costs, the 
Exchange believes that the proposed fees are reasonable, equitable and 
not unfairly discriminatory.
    As further discussed below, the SEC approved the CAT Funding Model, 
finding it was reasonable and that it equitably allocates fees among 
Participants and Industry Members. The Exchange believes that the 
proposed fees adopted pursuant to the CAT Funding Model approved by the 
SEC are reasonable, equitably allocated and not unfairly 
discriminatory.
(1) Implementation of CAT Funding Model in CAT NMS Plan
    Section 11.1(b) of the CAT NMS Plan states that ``[t]he 
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.'' Per Section 11.1(b) of the CAT NMS Plan, the 
Exchange has filed this fee filing to implement the Industry Member CAT 
fees included in the CAT Funding Model. The Exchange believes that this 
proposal is consistent with the Exchange Act because it is consistent 
with, and implements, the CAT Funding Model in the CAT NMS Plan, and is 
designed to assist the Exchange and its Industry Members in meeting 
regulatory obligations pursuant to the CAT NMS Plan. In approving the 
CAT NMS Plan, the SEC noted that the Plan ``is necessary and 
appropriate in the public interest, for the protection of investors and 
the maintenance of fair and orderly markets, to remove impediments to, 
and perfect the mechanism of a national market system, or is otherwise 
in furtherance of the purposes of the Act.'' \127\ Similarly, in 
approving the CAT Funding Model, the SEC concluded that the CAT Funding 
Model met this standard.\128\ As this proposal implements the Plan and 
the CAT Funding Model described therein, and applies specific 
requirements to Industry Members in compliance with the Plan, the 
Exchange believes that this

[[Page 30389]]

proposal furthers the objectives of the Plan, as identified by the SEC, 
and is therefore consistent with the Exchange Act.

(2) Calculation of Fee Rate for CAT Fee 2025-2 Is Reasonable
    The SEC has determined that the CAT Funding Model is reasonable and 
satisfies the requirements of the Exchange Act. Specifically, the SEC 
has concluded that the method for determining CAT Fees as set forth in 
Section 11.3 of the CAT NMS Plan, including the formula for calculating 
the Fee Rate, the identification of the parties responsible for payment 
and the transactions subject to the fee rate for CAT Fees, is 
reasonable and satisfies the Exchange Act.\129\ In each respect, as 
discussed above, CAT Fee 2025-2 is calculated, and would be applied, in 
accordance with the requirements applicable to CAT Fees as set forth in 
the CAT NMS Plan. Furthermore, as discussed below, the Exchange 
believes that each of the figures for the variables in the SEC-approved 
formula for calculating the fee rate for CAT Fee 2025-2 is reasonable 
and consistent with the Exchange Act. Calculation of Fee Rate 2025-2 
for CAT Fee 2025-2 requires the figures for Budgeted CAT Costs 2025-2, 
the executed equivalent share volume for the prior twelve months, the 
determination of the CAT Fee 2025-2 Period, and the projection of the 
executed equivalent share volume for the CAT Fee 2025-2 Period. Each of 
these variables is reasonable and satisfies the Exchange Act, as 
discussed throughout this filing.
---------------------------------------------------------------------------

    \129\ Id. at 62662-63.
---------------------------------------------------------------------------

(A) Budgeted CAT Costs 2025-2
    The formula for calculating a Fee Rate requires the amount of 
Budgeted CAT Costs to be recovered. Specifically, Section 
11.3(a)(iii)(B) of the CAT NMS Plan requires a fee filing to provide:

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) 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, 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.

    In accordance with this requirement, the Exchange has set forth the 
amount and type of Budgeted CAT Costs 2025-2 for each of these 
categories above.
    Section 11.3(a)(iii)(B) of the CAT NMS Plan also requires that the 
fee filing provide ``sufficient detail to demonstrate that the budget 
for the upcoming year, or part of year, as applicable, is reasonable 
and appropriate.'' As discussed below, the Exchange believes that the 
budget for the CAT Fee 2025-2 Period is ``reasonable and appropriate.'' 
Each of the costs included in CAT Fee 2025-2 are reasonable and 
appropriate because the costs are consistent with standard industry 
practice, based on the need to comply with the requirements of the CAT 
NMS Plan, incurred subject to negotiations performed on an arm's length 
basis, and/or are consistent with the needs of any legal entity, 
particularly one with no employees.
(i) Technology: Cloud Hosting Services
    In approving the CAT Funding Model, the Commission recognized that 
it is appropriate to recover budgeted costs related to cloud hosting 
services as a part of CAT Fees.\130\ CAT LLC determined that the 
budgeted costs related to cloud hosting services described in this 
filing are reasonable and should be included as a part of Budgeted CAT 
Costs 2025-2. As described above, the cloud hosting services costs 
reflect, among other things, the breadth of the CAT cloud activities, 
data volumes far in excess of the original volume estimates, the need 
for specialized cloud services given the volume and unique nature of 
the CAT, the processing time requirements of the Plan, and regular 
efforts to seek to minimize costs where permissible under the Plan. CAT 
LLC determined that use of cloud hosting services is necessary for 
implementation of the CAT, particularly given the substantial data 
volumes associated with the CAT, and that the fees for cloud hosting 
services negotiated by FCAT were reasonable, taking into consideration 
a variety of factors, including the expected volume of data and the 
breadth of services provided and market rates for similar 
services.\131\ Indeed, the actual costs of the CAT are far in excess of 
the original estimated costs of the CAT due to various factors, 
including the higher volumes and greater complexity of the CAT than 
anticipated when Rule 613 was originally adopted.
---------------------------------------------------------------------------

    \130\ Section 11.3(a)(iii)(B)(B)(1) of the CAT NMS Plan.
    \131\ For a discussion of the amount and type of cloud hosting 
services fees, see Section 3(a)(2)(C)(i) above.
---------------------------------------------------------------------------

    To comply with the requirements of the Plan, the breadth of the 
cloud activities related to the CAT is substantial. The cloud services 
not only include the production environment for the CAT, but they also 
include two industry testing environments, support environments for 
quality assurance and stress testing and disaster recovery 
capabilities. Moreover, the cloud storage costs are driven by the 
requirements of the Plan, which requires the storage of multiple 
versions of the data, from the original submitted version of the data 
through various processing steps, to the final version of the data.
    Data volume is a significant driver of costs for cloud hosting 
services. When the Commission adopted the CAT NMS Plan in 2016, it 
estimated that the CAT would need to receive 58 billion records per day 
\132\ and that annual operating costs for the CAT would range from 
$36.5 million to $55 million.\133\ In contrast to the 2016 projections, 
the actual daily Q1 2025 data volumes averaged 752 billion events per 
day.
---------------------------------------------------------------------------

    \132\ Appendix D-4 of the CAT NMS Plan at n.262.
    \133\ CAT NMS Plan Approval Order at 84801.
---------------------------------------------------------------------------

    In addition to the effect of the data volume on the cloud hosting 
costs, the processing timelines set forth in the Plan contribute to the 
cloud hosting costs. Although CAT LLC has proactively sought to manage 
cloud hosting costs while complying with the Plan, including through 
requests to the Commission for exemptive relief and amendments to the 
CAT NMS Plan to reduce costs, stringent CAT NMS Plan requirements do 
not allow for any material flexibility in cloud architecture design 
choices, processing timelines (e.g., the use of non-peak processing 
windows), or lower-cost storage tiers. As a result, the required CAT 
processing timelines contribute to the cloud hosting costs of the CAT.
    The costs for cloud hosting services also reflect the need for 
specialized cloud hosting services given the data volume and unique 
processing needs of the CAT. The data volume as well as the data 
processing needs of the CAT necessitate the use of cloud hosting 
services. The equipment, power and services required for an on-premises 
data model, the alternative to cloud hosting services, would be cost 
prohibitive. Moreover, as CAT was being developed, there were limited 
cloud hosting providers that could satisfy all the necessary CAT 
requirements, including the operational and security criteria. Over 
time, more providers offering cloud hosting services that would satisfy 
these criteria have entered the market. CAT LLC will continue to 
evaluate alternative cloud hosting services, recognizing that the time 
and cost to move to an alternative cloud provider would be substantial.

[[Page 30390]]

    The reasonableness of the cloud hosting services costs is further 
supported by key cost discipline mechanisms for the CAT--a cost-based 
funding structure, cost transparency, cost management efforts 
(including regular efforts to lower compute and storage costs where 
permitted by the Plan) and oversight. Together, these mechanisms help 
ensure the ongoing reasonableness of the CAT's costs and the level of 
fees assessed to support those costs.\134\
---------------------------------------------------------------------------

    \134\ See Securities Exchange Act Release No. 97151 (Mar. 15, 
2023), 88 FR 17086, 17117 (Mar. 21, 2023) (describing key cost 
discipline mechanisms for the CAT).
---------------------------------------------------------------------------

(ii) Technology: Operating Fees
    In approving the CAT Funding Model, the SEC recognized that it is 
appropriate to recover budgeted costs related to operating fees as a 
part of CAT Fees.\135\ CAT LLC determined that the budgeted costs 
related to operating fees described in this filing are reasonable and 
should be included as a part of Budgeted CAT Costs 2025-2.
---------------------------------------------------------------------------

    \135\ Section 11.3(a)(iii)(B)(B)(1) of the CAT NMS Plan.
---------------------------------------------------------------------------

    The operating fees would include the negotiated fees paid by CAT 
LLC to the Plan Processor to operate and maintain the system for order-
related information and to perform business operations related to the 
system, including compliance, security, testing, training, 
communications with the industry (e.g., management of the FINRA CAT 
Helpdesk, FAQs, website and webinars) and program management. CAT LLC 
determined that the selection of FCAT as the Plan Processor was 
reasonable and appropriate given its expertise with securities 
regulatory reporting, after a process of considering other potential 
candidates.\136\ CAT LLC also determined that the fixed price contract, 
negotiated on an arm's length basis with the goals of managing costs 
and receiving services required to comply with the CAT NMS Plan and 
Rule 613, was reasonable and appropriate, taking into consideration a 
variety of factors, including the breadth of services provided and 
market rates for similar types of activity.\137\ The services to be 
performed by FCAT for CAT Fee 2025-2 Period and the budgeted costs 
related to such services are described above.\138\

    The operating costs also include costs related to the receipt of 
market data. CAT LLC anticipates receiving certain market data from 
Algoseek during the CAT Fee 2025-2 Period. CAT LLC anticipates that 
Algoseek will provide data as set forth in the SIP Data requirements of 
the CAT NMS Plan and that the fees are reasonable and in line with 
market rates for market data received.\139\

(iii) Technology: CAIS Operating Fees
    In approving the CAT Funding Model, the SEC recognized that it is 
appropriate to recover budgeted costs related to CAIS operating fees as 
a part of CAT Fees.\140\ CAT LLC determined that the budgeted costs 
related to CAIS operating fees described in this filing are reasonable 
and should be included as a part of the Budgeted CAT Costs 2025-1. The 
CAIS operating fees would include the fees paid to the Plan Processor 
to operate and maintain CAIS and to perform the business operations 
related to the system, including compliance, security, testing, 
training, communications with the industry (e.g., management of the 
FINRA CAT Helpdesk, FAQs, website and webinars) and program management. 
CAT LLC determined that the fees for FCAT's CAIS-related services, 
negotiated on an arm's length basis with the goals of managing costs 
and receiving services required to comply with the CAT NMS Plan, taking 
into consideration a variety of factors, including the services to be 
provided and market rates for similar types of activity, are reasonable 
and appropriate.\141\ The services to be performed by FCAT for the CAT 
Fee 2025-2 Period and the budgeted costs for such services are 
described above.\142\

(iv) Technology: Change Request Fees
    In approving the CAT Funding Model, the SEC recognized that it is 
appropriate to recover budgeted costs related to change request fees as 
a part of CAT Fees.\143\ CAT LLC determined that the budgeted costs 
related to change request fees described in this filing are reasonable 
and should be included as a part of the Budgeted CAT Costs 2025-2. It 
is common practice to utilize a change request process to address 
evolving needs in technology projects. This is particularly true for a 
project like CAT that is the first of its kind, both in substance and 
in scale. The substance and costs of each of the change requests are 
evaluated by the Operating Committee and approved in accordance with 
the requirements for Operating Committee meetings. In each case, CAT 
LLC forecasts that the change requests will be necessary to implement 
the CAT. As described above,\144\ CAT LLC has included a reasonable 
placeholder budget amount for potential change requests that may arise 
during 2025. As noted above, the total budgeted costs for change 
requests during the CAT Fee 2025-2 Period represent a small percentage 
of the Budgeted CAT Costs 2025-2--that is, less than 1% of Budgeted CAT 
Costs 2025-2.

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

(v) Capitalized Developed Technology Costs
    In approving the CAT Funding Model, the SEC recognized that it is 
appropriate to recover budgeted costs related to capitalized developed 
technology costs as a part of CAT Fees.\145\ In general, capitalized 
developed technology costs would include costs related to, for example, 
certain development costs, costs related to certain modifications, 
upgrades and other changes to the CAT, CAIS implementation fees and 
license fees. The amount and type of budgeted capitalized developed 
technology costs for the CAT Fee 2025-2 Period, which relate to the 
CAIS software license fee and technology changes to be implemented by 
FCAT, are described in more detail above.\146\ Specifically, CAT LLC 
determined that it was reasonable not to include any capitalized 
developed technology costs in the Budgeted CAT Costs 2025-2.

(vi) Legal
    In approving the CAT Funding Model, the SEC recognized that it is 
appropriate to recover budgeted costs related to legal fees as a part 
of CAT Fees.\147\ CAT LLC determined that the budgeted legal costs 
described in this filing are reasonable and should be included as a 
part of the Budgeted CAT Costs 2025-2. Given the unique nature of the 
CAT, the number of parties involved with the CAT (including, for 
example, the SEC, Participants, Industry Members, and vendors) and the 
many regulatory, contractual and other issues associated with the CAT, 
the scope of the necessary legal services is substantial. CAT LLC 
determined that the scope of the proposed legal services is necessary 
to implement and maintain the CAT and that the legal rates reflect the 
specialized services necessary for such a project. CAT LLC determined 
to hire and continue to use each law firm based on a variety of 
factors, including their relevant expertise and fees. In each case,

[[Page 30391]]

CAT LLC determined that the fee rates were in line with market rates 
for specialized legal expertise. In addition, CAT LLC determined that 
the budgeted costs for the legal projects were appropriate given the 
breadth of the services provided. The services to be performed by each 
law firm for the CAT Fee 2025-2 Period and the budgeted costs related 
to such services are described above.\148\

(vii) Consulting
    In approving the CAT Funding Model, the SEC recognized that it is 
appropriate to recover budgeted consulting costs as a part of CAT 
Fees.\149\ CAT LLC determined that the budgeted consulting costs 
described in this filing are reasonable and should be included as a 
part of Budgeted CAT Costs 2025-2. Because there are no CAT employees 
\150\ and because of the significant number of issues associated with 
the CAT, the consultants are budgeted to provide assistance in the 
management of various CAT matters and the processes related to such 
matters.\151\ CAT LLC determined the budgeted consulting costs were 
appropriate, as the consulting services were to be provided at 
reasonable market rates that were comparable to the rates charged by 
other consulting firms for similar work. Moreover, the total budgeted 
costs for such consulting services were appropriate in light of the 
breadth of services provided by Deloitte. The services budgeted to be 
performed by Deloitte and the budgeted costs related to such services 
are described above.\152\

(viii) Insurance
    In approving the CAT Funding Model, the SEC recognized that it is 
appropriate to recover budgeted insurance costs as a part of CAT 
Fees.\153\ CAT LLC determined that the budgeted insurance costs 
described in this filing are reasonable and should be included as a 
part of the Budgeted CAT Costs 2025-2. CAT LLC determined that it is 
common practice to have directors' and officers' liability insurance, 
and errors and omissions liability insurance. CAT LLC further 
determined that it was important to have cyber security insurance given 
the nature of the CAT, and such a decision is consistent with the CAT 
NMS Plan, which states that the cyber incident response plan may 
include ``[i]nsurance against security breaches.'' \154\ As discussed 
above,\155\ CAT LLC determined that the budgeted insurance costs were 
appropriate given its prior experience with this market and an analysis 
of the alternative insurance offerings. Based on this analysis, CAT LLC 
determined that the selected insurance policies provided appropriate 
coverage at reasonable market rates.\156\

(ix) Professional and Administration
    In approving the CAT Funding Model, the SEC recognized that it is 
appropriate to recover budgeted professional and administration costs 
as a part of CAT Fees.\157\ CAT LLC determined that the budgeted 
professional and administration costs described in this filing are 
reasonable and should be included as a part of Budgeted CAT Costs 2025-
2. Because there are no CAT employees, all required accounting, 
financial, tax, cash management and treasury functions for CAT LLC have 
been outsourced at market rates. In addition, the required annual 
financial statement audit of CAT LLC is included in professional and 
administration costs, which costs are also at market rates. The 
services performed by Anchin and Grant Thornton and the costs related 
to such services are described above.\158\

    CAT LLC anticipates continuing to make use of Anchin, a financial 
advisory firm, to assist with financial matters for the CAT. CAT LLC 
determined that the budgeted costs for Anchin were appropriate, as the 
financial advisory services were to be provided at reasonable market 
rates that were comparable to the rates charged by other such firms for 
similar work. Moreover, the total budgeted costs for such financial 
advisory services were appropriate in light of the breadth of services 
provided by Anchin. The services budgeted to be performed by Anchin and 
the budgeted costs related to such services are described above.\159\

were appropriate, as the accounting services were to be provided at 
reasonable market rates that were comparable to the rates charged by 
other such firms for similar work. Moreover, the total budgeted costs 
for such accounting services were appropriate in light of the breadth 
of services provided by Grant Thornton. The services budgeted to be

(x) Public Relations Costs
    In approving the CAT Funding Model, the SEC recognized that it is 
appropriate to recover budgeted public relations costs as a part of CAT 
Fees.\161\ However, as described above,\162\ CAT LLC determined not to 
include any public relations costs in Budgeted CAT Costs 2025-2. CAT 
LLC determined that it was reasonable not include any public relations 
costs in the Budgeted CAT Costs 2025-2.
---------------------------------------------------------------------------

    \161\ Section 11.3(a)(iii)(B)(B)(6) of the CAT NMS Plan.
    \162\ See Section 3(a)(2)(C)(x) above.
---------------------------------------------------------------------------

(xi) Reserve
    In approving the CAT Funding Model, the SEC recognized that it is 
appropriate to recover budgeted reserve costs as a part of CAT 
Fees.\163\ CAT LLC determined that the reserve in the amount of 25% of 
the Updated 2025 CAT Budget (other than the reserve) complies with the 
requirements of the CAT NMS Plan related to a reserve, is a reasonable 
amount, and, therefore, should be included as a part of the Updated 
2025 CAT Budget.
---------------------------------------------------------------------------

    \163\ Section 11.3(a)(iii)(B)(B) of the CAT NMS Plan.
---------------------------------------------------------------------------

    In its approval order for the CAT Funding Model, the Commission 
stated that it would be reasonable for the annual operating budget for 
the CAT to ``include a reserve of not more than 25% of the annual 
budget.'' \164\ In making this statement, the Commission noted the 
following:
---------------------------------------------------------------------------

    \164\ CAT Funding Model Approval Order at 62657.

    Because 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. Funding for the CAT, as 
noted in Section 11.1(b), is the responsibility of the Participants 
and the industry. Because CAT fees are charged based on the budget, 
which is based on anticipated volume, it is reasonable to have a 
reserve on hand to prevent a shortfall in the event there is an 
unexpectedly high volume in a given year. A reserve would help to 
assure that the CAT

[[Page 30392]]

has sufficient resources to cover costs should there be 
unanticipated costs or costs that are higher than expected.\165\
---------------------------------------------------------------------------

    \165\ Id.

    The SEC also recognized that a reserve would help address the 
difficulty in predicting certain variable CAT costs, like trading 
volume.\166\ The SEC also recognized that CAT fees will be collected 
approximately three months after trading activity on which a CAT fee is 
based, or 25% of the year, and that the reserve would be available to 
address funding needs related to this three-month delay.\167\ The 
inclusion of the proposed reserve in the Updated 2025 CAT Budget would 
provide each of these benefits to the CAT. The reserve is discussed 
further above.\168\

    \168\ See Section 3(a)(2)(C)(xi) above.
---------------------------------------------------------------------------

    As discussed further below,\169\ however, a surplus reserve balance 
in excess of the budgeted 25% reserve has been collected through the 
first quarter of 2025 and has been budgeted to be collected during the 
second quarter of 2025. Accordingly, the Updated 2025 CAT Budget 
indicates that this surplus would be used to offset a portion of CAT 
costs for the third and fourth quarters of 2025, thereby reducing the 
fee rate for CAT Fee 2025-2 ($0.000009 per executed equivalent share) 
as compared to CAT Fee 2025-1 ($0.000022 per executed equivalent 
share), and that no additional reserve is budgeted to be collected 
during the third and fourth quarters of 2025.
---------------------------------------------------------------------------

    \169\ See Section 3(b)(2)(B) below.
---------------------------------------------------------------------------

(B) Reconciliation of Budget to the Collected Fees
    The CAT NMS Plan also requires fee filings for Prospective CAT Fees 
to include ``a discussion of how the budget is reconciled to the 
collected fees.'' \170\ As discussed above,\171\ the Updated 2025 CAT 
Budget states that CAT LLC had accrued $70,942,596 for the reserve as 
of the beginning of 2025, and an additional $28,846,075 during the 
first quarter of 2025, from the collection of CAT Fees 2024-1 and 2025-
1 and the related Participant CAT Fees. In addition, the Updated 2025 
CAT Budget anticipates the collection of an additional $11,821,477 
during the second quarter of 2025 via CAT Fee 2025-1 and the related 
Participant CAT Fee. Accordingly, the Updated 2025 CAT Budget estimates 
that CAT LLC would maintain a 25% reserve amount of $57,083,638 and 
collect a surplus reserve amount through June 2025 of $54,526,412 over 
the 25% reserve amount of $57,083,638.\172\ Such surplus reserve 
balance of $54,526,412 would be used to offset a portion of CAT costs 
for the third and fourth quarters of 2025, thereby reducing the fee 
rate for CAT Fee 2025-2 ($0.000009 per executed equivalent share) as 
compared to CAT Fee 2025-1 ($0.000022 per executed equivalent share).
---------------------------------------------------------------------------

    \170\ Section 11.3(a)(iii)(B)(C) of the CAT NMS Plan.
    \171\ See Section 3(a)(2)(C)(xi) above.
    \172\ This calculation is ($70,942,596 + $28,846,075 + 
$11,821,477)-$57,083,638 = $54,526,412.
---------------------------------------------------------------------------

(C) Total Executed Equivalent Share Volume for the Prior 12 Months
    The total executed equivalent share volume of transactions in 
Eligible Securities for the period from April 2024 through March 2025 
was 4,580,287,680,646.28 executed equivalent shares. CAT LLC determined 
the total executed equivalent share volume for the prior twelve months 
by counting executed equivalent shares in the same manner as it counts 
executed equivalent shares for CAT billing purposes.\173\
---------------------------------------------------------------------------

    \173\ See Section 3(a)(2)(D) above.
---------------------------------------------------------------------------

(D) Projected Executed Equivalent Share Volume for the CAT Fee 2025-2 
Period
    CAT LLC has determined that the projected total executed equivalent 
share volume for the six months of CAT Fee 2025-2 Period by multiplying 
by one-half the executed equivalent share volume for the prior twelve 
months: one-half times 4,580,287,680,646.28 executed equivalent 
shares.\174\ CAT LLC determined that such an approach was reasonable as 
the CAT's annual executed equivalent share volume has remained 
relatively constant in recent years. For example, the executed 
equivalent share volume for 2021 was 3,963,697,612,395, the executed 
equivalent share volume for 2022 was 4,039,821,841,560.31, the executed 
equivalent share volume for 2023 was 3,868,940,345,680.6, and the 
executed equivalent share volume for 2024 was 4,295,884,600,069.41.

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

(E) Actual Fee Rate for CAT Fee 2025-2
(i) Decimal Places
    As noted in the approval order for the CAT Funding Model, as a 
practical matter, the fee filing for a CAT Fee would provide the exact 
fee per executed equivalent share to be paid for each CAT Fee, by 
multiplying the Fee Rate by one-third and describing the relevant 
number of decimal places for the fee rate.\175\ Accordingly, proposed 
paragraph (a)(5)(B) of the fee schedule would set forth a fee rate of 
$0.000009 per executed equivalent share. This fee rate is calculated by 
multiplying Fee Rate 2025-2 by one-third and rounding the result to six 
decimal places. CAT LLC determined that the use of six decimal places 
is reasonable as it balances the accuracy of the calculation with the 
potential systems and other impracticalities of using additional 
decimal places in the calculation.\176\
---------------------------------------------------------------------------

    \175\ CAT Funding Model Approval Order at 62658, n.658.
    \176\ See Section 3(a)(5)(A) above.
---------------------------------------------------------------------------

(ii) Reasonable Fee Level
    The Exchange believes that charging CAT Fee 2025-2 with a fee rate 
of $0.000009 per executed equivalent share is reasonable because it 
provides for a revenue stream for the Company that is aligned with the 
Budgeted CAT Costs 2025-2. Moreover, the Exchange believes that the 
level of the fee rate is reasonable, as it is less than CAT Fee 2025-1 
and is comparable to other transaction-based fees. Indeed, CAT Fee 
2025-2 is significantly lower than fees previously assessed pursuant to 
Section 31 (e.g., $0.0009 per share to $0.0004 per share),\177\ and, as 
a result, the magnitude of CAT Fee 2025-2 is small, and therefore will 
mitigate any potential adverse economic effects or inefficiencies.\178\
---------------------------------------------------------------------------

    \177\ CAT Funding Model Approval Order at 62663, 62682. In 
explaining the comparison of Section 31 fees to CAT fees in the CAT 
Funding Model Approval Order, the SEC noted that ``Section 31 fees 
are expressed per dollar volume traded. Translating this to a per 
share range involves identifying reasonable high and low trade 
sizes. The lower end of this range comes from the 25th percentile in 
$ trade size of 1,200 and share trade size of 71 from the first 
quarter of 2021. The higher end of this range comes from the 75th 
percentile in $ trade size of 5,200 and share trade size of 300 from 
the first quarter of 2021. Section 31 fees have ranged from $5.10 
per $Million to $23.10 per $Million from Oct. 1, 2016 to Mar. 1, 
2023.'' Id. at 62682., n.1100. In 2024, Section 31 fees were raised 
further to $27.80 per million dollars.
    \178\ Id.
---------------------------------------------------------------------------

(3) CAT Fee 2025-2 Provides for An Equitable Allocation of Fees
    CAT Fee 2025-2 provides for an equitable allocation of fees, as it 
equitably allocates CAT costs between and among the Participants and 
Industry Members. The SEC approved the CAT Funding Model, finding that 
each aspect of the CAT Funding Model satisfied the requirements of the 
Exchange Act, including the formula for calculating CAT Fees as well as 
the Industry Members to be charged the CAT Fees.\179\ In approving the 
CAT Funding Model, the SEC stated that ``[t]he Participants have 
sufficiently demonstrated that the proposed

[[Page 30393]]

allocation of fees is reasonable.'' \180\ Accordingly, the CAT Funding 
Model sets forth the requirements for allocating fees related to 
Budgeted CAT Costs among Participants and Industry Members, and the fee 
filings for CAT Fees must comply with those requirements.
---------------------------------------------------------------------------

    \179\ See Section 11.3(a) of the CAT NMS Plan.
    \180\ CAT Funding Model Approval Order at 62629.
---------------------------------------------------------------------------

    CAT Fee 2025-2 provides for an equitable allocation of fees as it 
complies with the requirements regarding the calculation of CAT Fees as 
set forth in the CAT NMS Plan. For example, as described above, the 
calculation of CAT Fee 2025-2 complies with the formula set forth in 
Section 11.3(a) of the CAT NMS Plan. In addition, CAT Fee 2025-2 would 
be charged to CEBBs and CEBSs in accordance with Section 11.3(a) of the 
CAT NMS Plan. Furthermore, the Participants would be charged for their 
designated share of the Budgeted CAT Costs 2025-2 through a fee 
implemented via the CAT NMS Plan, which would have the same fee rate as 
CAT Fee 2025-2.
    In addition, as discussed above, each of the inputs into the 
calculation of CAT Fee 2025-2--the Budgeted CAT Costs 2025-2, the count 
for the executed equivalent share volume for the prior 12 months, and 
the projected executed equivalent share volume for the CAT Fee 2025-2 
Period--are reasonable. Moreover, these inputs lead to a reasonable fee 
rate for CAT Fee 2025-2 that is lower than other fee rates for 
transaction-based fees. A reasonable fee rate allocated in accordance 
with the requirements of the CAT Funding Model provides for an 
equitable allocation of fees.
(4) CAT Fee 2025-2 Is Not Unfairly Discriminatory
    CAT Fee 2025-2 is not an unfairly discriminatory fee. The SEC 
approved the CAT Funding Model, finding that each aspect of the CAT 
Funding Model satisfies the requirements of the Exchange Act. In 
reaching this conclusion, the SEC analyzed the potential effect of CAT 
Fees calculated pursuant to the CAT Funding Model on affected 
categories of market participants, including Participants (including 
exchanges and FINRA), Industry Members (including subcategories of 
Industry Members, such as alternative trading systems, CAT Executing 
Brokers and market makers), and investors generally, and considered 
market effects related to equities and options, among other things. CAT 
Fee 2025-2 complies with the requirements regarding the calculation of 
CAT Fees as set forth in the CAT NMS Plan. In addition, as discussed 
above, each of the inputs into the calculation of CAT Fee 2025-2 and 
the resulting fee rate for CAT Fee 2025-2 is reasonable. Therefore, CAT 
Fee 2025-2 does not impose an unfairly discriminatory fee on Industry 
Members.
    The Exchange believes the proposed fees established pursuant to the 
CAT Funding Model promote just and equitable principles of trade, and, 
in general, protect investors and the public interest, and are provided 
in a transparent manner and with specificity in the fee schedule. The 
Exchange also believes that the proposed fees are reasonable because 
they would provide ease of calculation, ease of billing and other 
administrative functions, and predictability of a fee based on fixed 
rate per executed equivalent share. Such factors are crucial to 
estimating a reliable revenue stream for CAT LLC and for permitting 
Exchange members to reasonably predict their payment obligations for 
budgeting purposes.

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

    Section 6(b)(8) of the Act \181\ requires that the Exchange's rules 
not impose any burden on competition that is not necessary or 
appropriate in furtherance of the purpose of the Exchange Act. The 
Exchange does not believe that the proposed rule change will result in 
any burden on competition that is not necessary or appropriate in 
furtherance of the purposes of the Act. The Exchange notes that CAT Fee 
2025-2 implements provisions of the CAT NMS Plan that were approved by 
the Commission and is designed to assist the Exchange in meeting its 
regulatory obligations pursuant to the Plan.
---------------------------------------------------------------------------

    \181\ 15 U.S.C. 78f(b)(8).
---------------------------------------------------------------------------

    In addition, all Participants (including exchanges and FINRA) are 
proposing to introduce CAT Fee 2025-2 on behalf of CAT LLC to implement 
the requirements of the CAT NMS Plan. Therefore, this is not a 
competitive fee filing, and, therefore, it does not raise competition 
issues between and among the Participants.
    Furthermore, in approving the CAT Funding Model, the SEC analyzed 
the potential competitive impact of the CAT Funding Model, including 
competitive issues related to market services, trading services and 
regulatory services, efficiency concerns, and capital formation.\182\ 
The SEC also analyzed the potential effect of CAT fees calculated 
pursuant to the CAT Funding Model on affected categories of market 
participants, including Participants (including exchanges and FINRA), 
Industry Members (including subcategories of Industry Members, such as 
alternative trading systems, CAT Executing Brokers and market makers), 
and investors generally, and considered market effects related to 
equities and options, among other things. Based on this analysis, the 
SEC approved the CAT Funding Model as compliant with the Exchange Act. 
CAT Fee 2025-2 is calculated and implemented in accordance with the CAT 
Funding Model as approved by the SEC.
---------------------------------------------------------------------------

    \182\ CAT Funding Model Approval Order at 62676-86.
---------------------------------------------------------------------------

    As discussed above, each of the inputs into the calculation of CAT 
Fee 2025-2 is reasonable and the resulting fee rate for CAT Fee 2025-2 
calculated in accordance with the CAT Funding Model is reasonable. 
Therefore, CAT Fee 2025-2 would not impose any burden on competition 
that is not necessary or appropriate in furtherance of the purpose of 
the Exchange Act.

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

    No written comments were either solicited or received.

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

    The foregoing rule change has become effective pursuant to Section 
19(b)(3)(A) of the Act \183\ and paragraph (f)(2) of Rule 19b-4 
thereunder.\184\ At any time within 60 days of the filing of the
