SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-105449; File No. SR-FINRA-2026-010]


Self-Regulatory Organizations; Financial Industry Regulatory 
Authority, Inc.; Notice of Filing and Immediate Effectiveness of a 
Proposed Rule Change To Amend FINRA Rule 6897 (Consolidated Audit Trail 
Funding Fees) To Establish Fees for Industry Members Related to 
Reasonably Budgeted CAT Costs of the National Market System Plan 
Governing the Consolidated Audit Trail for May 1, 2026 Through December 
31, 2026

May 12, 2026.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given that 
on April 28, 2026, the Financial Industry Regulatory Authority, Inc. 
(``FINRA'') filed with the Securities and Exchange Commission (``SEC'' 
or ``Commission'') the proposed rule change as described in Items I, 
II, and III below, which Items have been prepared by FINRA. FINRA has 
designated the proposed rule change as ``establishing or changing a 
due, fee or other charge'' under Section 19(b)(3)(A)(ii) of the Act \3\ 
and Rule 19b-4(f)(2) thereunder,\4\ which renders the proposal 
effective upon receipt of this filing by the Commission. The Commission 
is publishing this notice to solicit comments on the proposed rule

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

    FINRA is proposing to amend FINRA Rule 6897 (Consolidated Audit 
Trail Funding Fees) to establish fees for Industry Members \5\ related 
to reasonably budgeted Consolidated Audit Trail (``CAT'') costs of the 
National Market System Plan Governing the Consolidated Audit Trail (the 
``CAT NMS Plan'' or ``Plan'') for the period from May 1, 2026 through 
December 31, 2026. These fees would be payable to Consolidated Audit 
Trail, LLC (``CAT LLC'' or the ``Company'') and referred to as ``CAT 
Fee 2026-1.'' The fee rate for CAT Fee 2026-1 would be $0.000001 per 
executed equivalent share. CAT Executing Brokers will receive their 
first monthly invoice for CAT Fee 2026-1 in June 2026 calculated based 
on their transactions as CAT Executing Brokers for the Buyer (``CEBB'') 
and/or CAT Executing Brokers for the Seller (``CEBS'') in May 2026. As 
described further below, CAT Fee 2026-1 is anticipated to be in place 
for eight months, and is anticipated to recover approximately two-
thirds of the costs set forth in the reasonably budgeted CAT costs for 
2026.
---------------------------------------------------------------------------

    \5\ An ``Industry Member'' is defined as ``a member of a 
national securities exchange or a member of a national securities 
association.'' See FINRA Rule 6810(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 FINRA Rule 6800 Series (Consolidated 
Audit Trail Compliance Rule).
---------------------------------------------------------------------------

    The text of the proposed rule change is available on FINRA's 
website at <a href="http://www.finra.org">http://www.finra.org</a> and at the principal office of FINRA.

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

    In its filing with the Commission, FINRA 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. FINRA 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 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.\6\ On November 15, 2016, the 
Commission approved the CAT NMS Plan.\7\ 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.\8\ The Operating Committee adopted a revised 
funding model to fund the CAT (``CAT Funding Model''). On March 16, 
2026, the Commission approved the CAT Funding Model after concluding 
that the model satisfied the requirements of Section 11A of the 
Exchange Act and Rule 608 thereunder.\9\
---------------------------------------------------------------------------

    \6\ See Securities Exchange Act Release No. 67457 (July 18, 
2012), 77 FR 45722 (August 1, 2012).
    \7\ See Securities Exchange Act Release No. 79318 (November 15, 
2016), 81 FR 84696 (November 23, 2016) (``CAT NMS Plan Approval 
Order'').
    \8\ See Section 11.1(b) of the CAT NMS Plan.
    \9\ See Securities Exchange Act Release No. 105003 (March 16, 
2026), 91 FR 13410 (March 19, 2026) (``CAT Funding Model Approval 
Order''). This CAT Funding Model replaced the prior funding model 
that was approved by the Commission on September 6, 2023. See 
Securities Exchange Act Release. No. 98290 (September 6, 2023), 88 
FR 62628 (September 12, 2023).
---------------------------------------------------------------------------

    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'').\10\
---------------------------------------------------------------------------

    \10\ Under the CAT Funding Model, the Operating Committee may 
establish CAT Fees related to CAT costs going forward. See Section 
11.3(a) of the CAT NMS Plan. This filing only establishes CAT Fee 
2026-1 related to reasonably budgeted CAT costs for the period from 
May 1, 2026 through December 31, 2026 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. See 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 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').'' \11\ 
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

[[Page 28065]]

equivalent shares in the transaction by one-third and by the Fee Rate.
---------------------------------------------------------------------------

    \11\ See Section 11.3(a) of the CAT NMS Plan.
---------------------------------------------------------------------------

    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 allocates the 
remaining one-third of the budgeted CAT costs to the Participants.\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\
---------------------------------------------------------------------------

    \12\ See Section 11.3(a)(iii)(A) of the CAT NMS Plan.
    \13\ See Section 11.3(a)(ii)(A) of the CAT NMS Plan.
    \14\ See Section 11.3(a)(ii) of the CAT NMS Plan.
    \15\ See Section 11.3(a)(i)(A)(I) of the CAT NMS Plan.
    \16\ See CAT Funding Model Approval Order, 91 FR 13410, 13448.
    \17\ See Section 11.3(a)(ii) and Appendix B of the CAT NMS Plan.
---------------------------------------------------------------------------

    CAT LLC proposes to charge CEBBs and CEBSs (as described in more 
detail below) CAT Fee 2026-1 to recover the reasonably budgeted CAT 
costs for the period from May 1, 2026 through December 31, 2026 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 2026-1, in accordance 
with the CAT NMS Plan.
---------------------------------------------------------------------------

    \18\ See Section 11.1(b) of the CAT NMS Plan.
    \19\ See Section 11.3(a)(i)(A)(I) of the CAT NMS Plan.
---------------------------------------------------------------------------

(1) CAT Executing Brokers
    CAT Fee 2026-1 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 
appropriate. 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. See CAT 
Funding Model Approval Order, 91 FR 13410, 13413.

(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\
---------------------------------------------------------------------------

    \21\ See Section 1.1 of the CAT NMS Plan. In its approval order 
for the CAT Funding Model, the Commission ``recognize[d] that 
Industry Members may pass-through CAT fees for customer executed 
volume.'' See CAT Funding Model Approval Order, 91 FR 13410, 13424.

    Fields Nos. 26 and 28 of the Participant Technical Specifications, 
listed below, indicate the CAT Executing Brokers for transactions 
executed otherwise than on an exchange:\22\
---------------------------------------------------------------------------

    \22\ Supplementary Material .01 to Rule 6897 provides clarity as 
to the manner in which the CAT Executing Brokers for transactions 
executed otherwise than on an exchange would be determined. 
Specifically, for a transaction in an Eligible Security executed 
otherwise than on an exchange and required to be reported to a FINRA 
Trade Reporting Facility (``TRF''), the FINRA OTC Reporting Facility 
(``ORF''), or the FINRA Alternative Display Facility (``ADF''), the 
CEBB and CEBS are the members identified as the executing broker and 
the contra-side executing broker in the TRF/ORF/ADF transaction data 
event in CAT Data. In those circumstances where there is a non-
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 
member identified as the executing broker in the TRF/ORF/ADF 
transaction data event would be treated as, and be required to pay 
the fee assessed to, both the CEBB and CEBS.
    \23\ See Table 62, Section 6.1 (TRF/ORF/ADF Transaction Data 
Event) of the CAT Reporting Technical Specifications for Plan 
Participants.

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

(2) Calculation of Fee Rate 2026-1
    The Operating Committee determined the Fee Rate to be used in 
calculating CAT Fee 2026-1 (``Fee Rate 2026-1'') by dividing the 
reasonably budgeted CAT costs (``Budgeted CAT Costs 2026-1'') for the 
period from May 1, 2026 through December 31, 2026 (``CAT Fee 2026-1 
Period'') by the reasonably projected total executed share volume of 
all transactions in Eligible Securities for the eight-month recovery 
period, as discussed in detail below.\24\ Based on this calculation, 
the Operating Committee has determined that Fee Rate 2026-1 would be 
0.000003799483243631228 per executed equivalent share. This rate is 
then divided by three and rounded to determine the fee rate of 0.000001 
per executed equivalent share that will be assessed to CEBBs and CEBSs, 
as also discussed in detail below.
---------------------------------------------------------------------------

    \24\ See Section 11.3(a)(i) of the CAT NMS Plan.
---------------------------------------------------------------------------

(A) CAT Fee 2026-1 Period
    CAT LLC proposes to implement CAT Fee 2026-1. CAT LLC proposes to

[[Page 28066]]

commence CAT Fee 2026-1 during the year, rather than at the beginning 
of the year. Accordingly, CAT Fee 2026-1 ``would be calculated as 
described in paragraph (II)'' of Section 11.3(a)(i)(A) of the CAT NMS 
Plan,\25\ 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.'' \26\ For CAT Fee 
2026-1, the reasonably budgeted CAT costs for ``the remainder of the 
year'' are the reasonably budgeted CAT costs from May 1, 2026 through 
December 31, 2026 as set forth in the updated annual budget for 2026 
for CAT LLC approved by the Operating Committee on March 31, 2026 
(``Updated 2026 CAT Budget'').\27\
---------------------------------------------------------------------------

    \25\ See Section 11.3(a)(i)(A)(IV) of the CAT NMS Plan.
    \26\ See Section 11.3(a)(i)(A)(II) of the CAT NMS Plan.
    \27\ See Consolidated Audit Trail, LLC 2026 Financial and 
Operating Budget (Updated 2026 CAT Budget), <a href="https://www.catnmsplan.com/sites/default/files/2026-04/03.31.26-CAT-2026-Budget.pdf">https://www.catnmsplan.com/sites/default/files/2026-04/03.31.26-CAT-2026-Budget.pdf</a>.
---------------------------------------------------------------------------

(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.\28\
---------------------------------------------------------------------------

    \28\ See 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 provides an appropriate basis for 
the calculation of CAT fees.'' See CAT Funding Model Approval Order, 
91 FR 13410, 13413.
---------------------------------------------------------------------------

(C) Budgeted CAT Costs 2026-1
    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 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.'' \29\ 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:
---------------------------------------------------------------------------

    \29\ See 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 2026 for CAT LLC 
(``Original 2026 CAT Budget'') on December 11, 2025.\30\ On March 31, 
2026, the Operating Committee approved an updated budget for 2026, 
referred to as the Updated 2026 CAT Budget. The Updated 2026 CAT Budget 
includes actual costs for each category for January and February 2026, 
with updated estimated costs for the remainder of the year. The updated 
costs for May through December as included in the Updated 2026 CAT 
Budget (i.e., Budgeted CAT Costs 2026-1) are the costs used in 
calculating CAT Fee 2026-1.\31\ The 2026 CAT budgets, both the Original 
2026 CAT Budget and the Updated 2026 CAT Budget, were prepared on the 
accrual basis of accounting.\32\
---------------------------------------------------------------------------

    \30\ See Consolidated Audit Trail, LLC 2026 Financial and 
Operating Budget Version1_12.8.25, <a href="https://www.catnmsplan.com/sites/default/files/2025-12/12.08.25-CAT-LLC-2026-Financial_and_Operating_Budget.pdf">https://www.catnmsplan.com/sites/default/files/2025-12/12.08.25-CAT-LLC-2026-Financial_and_Operating_Budget.pdf</a>.
    \31\ The version of the Updated 2026 CAT Budget set forth on the 
CAT website is presented on a quarterly basis, but is prepared based 
on more granular detail. The costs for May and June are estimated 
based on two-thirds of costs for Q2 where the budgeted monthly 
amounts are consistent. For those cases in which the costs for a 
category vary from month to month in Q2, the specific budgeted 
amounts for May and June are noted.
    \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 2026-1 would 
be 15,149,648. CEBBs collectively will be responsible for one-third of 
the Budgeted CAT Costs 2026-1 (which is 5,049,882.67), and CEBSs 
collectively will be responsible for one-third of the Budgeted CAT 
Costs 2026-1 (which is 5,049,882.67).
    The following describes in detail the Budgeted CAT Costs 2026-1 for 
CAT Fee 2026-1. 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\ See Section 11.3(a)(iii)(B) of the CAT NMS Plan.

    Each of the costs described below is reasonable, appropriate and 
necessary for the creation, implementation and maintenance of CAT.
    The following table breaks down the Budgeted CAT Costs 2026-1 into 
the categories set forth in Section 11.3(a)(iii)(B) of the CAT NMS 
Plan.\34\ The Budgeted CAT Costs 2026-1 reflect the costs for May 
through December as included in the Updated 2026 CAT Budget. The 
Budgeted CAT Costs 2026-1 are the costs used in calculating CAT Fee 
2026-1.
---------------------------------------------------------------------------

    \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.

------------------------------------------------------------------------
\a\ The non-cash amortization of these capitalized developed technology
  costs to be incurred during the CAT Fee 2026-1 Period have been
  appropriately excluded from the above table.\35\
\b\ Budgeted CAT Costs 2026-1 described in this table of costs were
  determined based on an analysis of a variety of factors, including
  historical costs/invoices, estimated costs from respective vendors/
  service providers, contractual terms with vendors/service providers,
  anticipated service levels and needs, and discussions with vendors and
  Participants.
\c\ This cost number for capitalized developed technology costs reflects
  (1) capitalized developed technology costs of 3,450,000 for May, 0 for
  June and 0 for the third and fourth quarters of 2026 as included in
  the Updated 2026 CAT Budget; and (2) 0 for the Software License Fee
  2026 for the second, third, and fourth quarters of 2026 as included in
  the Updated 2026 CAT Budget: (3,450,000 +0 + 0 + 0) + (0 + 0 + 0) =
  3,450,000.
\d\ This cost number for cloud hosting services reflects two-thirds of
  the cloud hosting services costs for the second quarter and the cloud
  hosting services for the third and fourth quarters of 2026 as included
  in the Updated 2026 CAT Budget: (2/3 x 18,700,000) + 18,700,000 +
  18,700,000 = 49,866,667.
\e\ This cost number for operating fees reflects (1) two-thirds of the
  Non-CAIS fixed operating fees for the second quarter and the Non-CAIS
  fixed operating fees for the third and fourth quarters of 2026 as
  included in the Updated 2026 CAT Budget and (2) two-thirds of the
  market data vendor fees for the second quarter and the market data
  vendor fees for the third and fourth quarter of 2026 as included in
  the Updated 2026 CAT Budget: ((2/3 x 7,191,853) + 7,191,853 +
  7,191,853) + ((2/3 x 192,630) + 192,630 + 192,630) = 19,691,953.
\f\ This cost number for CAIS operating fees reflects two-thirds of the
  CAIS fixed operating fees for the second quarter and the CAIS fixed
  operating fees for the third and fourth quarters of 2026 as included
  in the Updated 2026 CAT Budget: (2/3 x 5,317,147) + 5,317,147 +
  5,317,147 = 14,179,060.
\g\ This 0 cost number for change requests reflects the fact that there
  were no change request fees set forth in the Updated 2026 CAT Budget.
\h\ This cost number for legal services reflects two-thirds of the legal
  costs for the second quarter and the legal costs for the third and
  fourth quarters of 2026 as included in the Updated 2026 CAT Budget: (2/
  3 x 2,145,170) + 2,125,170 + 2,115,170 = 5,670,452.
\i\ This cost number for consulting services reflects two-thirds of the
  consulting costs for the second quarter and the consulting costs for
  the third and fourth quarters of 2026 as included in the Updated 2026
  CAT Budget: (2/3 x 384,734) + 384,734 + 384,734 = 1,025,957.
\j\ This cost number for insurance reflects two-thirds of the insurance
  costs for the second quarter and the insurance costs for the third and
  fourth quarters of 2026 as included in the Updated 2026 CAT Budget: (2/
  3 x 300,977) + 321,042 + 331,074 = 852,768.
\k\ This cost number for professional and administration services
  reflects two-thirds of the professional and administration costs for
  the second quarter and the professional and administration costs for
  the third and fourth quarters of 2026 as included in the Updated 2026
  CAT Budget: (2/3 x 280,932) + 280,932 + 280,932 = 749,151.
\l\ This 0 cost number of change requests reflects the fact that there
  were no change request fees set forth in the Updated 2026 CAT Budget.
\m\ This interest income reflects interest income (net of bank fees) of
  517,208 for May and June and interest income (net of bank fees) for
  the third and fourth quarters of 2026 as included in the Updated 2026
  CAT Budget: 517,208 + 571,010 + 365,164 = 1,453,382. Note that
  interest income for May and June 2026 of 517,208 is slightly less than
  two-thirds of 809,598 (which is 539,732) for the second quarter as the
  amount of interest income varies from month to month.
\n\ This amount for the use of the existing reserve is calculated by
  subtracting from the Accrued Liquidity Reserve Balance as of the
  Beginning of the Year in the Updated 2026 CAT Budget the 25%
  Incremental Liquidity Reserve Accrued during 2026 for the first
  quarter and for April of 2026 as included in the Updated 2026 CAT
  Budget: 155,403,378-(41,800,153 + 11,212,091) = 102,391,135. Note that
  the 25% Incremental Liquidity Reserved Accrued during 2026 for April
  2026 of 11,212,091 is slightly more than one-third of 33,366,432
  (which is 11,122,144) for the second quarter as the amount of the 25%
  Incremental Liquidity Reserved Accrued during 2026 varies from month
  to month.

    To the extent that CAT LLC enters into notes with Participants or 
others to pay costs incurred during the period in which CAT Fee 2026-1 
is in effect, CAT LLC will use the proceeds from CAT Fee 2026-1 and the 
related Participant CAT fees to repay such notes.

(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 49,866,667 in technology 
costs for cloud hosting services for the CAT Fee 2026-1 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 2026-1 Period.
    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 Reference Database (previously referred to as 
the Customer and Account Information System, or ``CAIS'').\38\ It is 
anticipated that such cloud hosting services will continue during the 
CAT Fee 2026-1 Period.
---------------------------------------------------------------------------

    \38\ On January 13, 2026, the SEC approved an amendment to the 
CAT NMS Plan relating to the Customer and Account Information System 
(referred to as ``CAIS''). Effective with this amendment, CAIS has 
been renamed as the ``Reference Database.'' See Securities Exchange 
Act Release No. 104586 (January 13, 2026), 91 FR 2164 (January 16, 
2026) (``CAIS Amendment''). The SEC subsequently approved another 
amendment to the CAT NMS Plan to implement various cost savings 
measures that made further changes to the Reference Database. See 
Securities Exchange Act Release No. 105107 (March 27, 2026), 91 FR 
16284 (April 1, 2026) (``Cost Savings Amendment'').
---------------------------------------------------------------------------

    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.\39\ The greater the amount of CAT Data, the greater 
the cost of AWS services to CAT LLC. During the CAT Fee 2026-1 Period, 
it is expected that AWS would 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,'' \40\ and that 
``[i]t is expected that the Central Repository will grow to more than 
29 petabytes of raw, uncompressed data.'' \41\ In contrast with those 
estimates, the Q3 2025 data volumes averaged 792 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.
---------------------------------------------------------------------------

    \39\ 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 Item 
II.A.2.(2)(A)(i) below.
    \40\ See Section 1.3 of Appendix D-4 of the CAT NMS Plan, n.262.
    \41\ See Section 1.3 of Appendix D-5 of the CAT NMS Plan.
---------------------------------------------------------------------------

    CAT LLC estimates that the budget for cloud hosting services costs 
during the CAT Fee 2026-1 Period will be approximately 49,866,667.\42\ 
The budget for cloud hosting services costs during the CAT Fee 2026-1 
Period is calculated based on the Updated 2026 CAT Budget. 
Specifically, this estimate was calculated by adding two-thirds of the 
cloud hosting services costs for the second quarter and the cloud 
hosting services for the third and fourth quarters of 2026 as included 
in the Updated 2026 CAT Budget.\43\
---------------------------------------------------------------------------

    \42\ See chart entitled ``Budgeted CAT Costs 2026-1'' in Item 
II.A.1(2)(C) above.
    \43\ This calculation is (\2/3\ x 18,700,000) + 18,700,000 + 
18,700,000 = 49,866,667.
---------------------------------------------------------------------------

    CAT LLC estimated the budget for the cost for cloud hosting 
services for the CAT Fee 2026-1 Period based on an assumption of 35% 
annual year-over-year volume growth for the transaction database and an 
assumption of 5% annual year-over-year volume growth for the Reference 
Database. CAT LLC determined these growth assumptions in coordination 
with FCAT.\44\
---------------------------------------------------------------------------

    \44\ 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 2026-1 Period is the same process by which CAT 
LLC estimated the cloud hosting services costs for the Original 2026 
CAT Budget.
    The Original 2026 CAT Budget estimated a budget for cloud hosting 
services of 17,200,000 for January and February 2026. The actual costs 
for cloud hosting services for January and February 2026, which are set 
forth in the Updated 2026 CAT Budget, were 12,829,362. Therefore, the 
variance between budgeted and actual cloud hosting services costs for 
January and February 2026 was an approximate decrease of 4,370,638 as a 
result of lower volumes and a change in functionality.\45\ Accordingly, 
CAT LLC believes that the process for estimating the budgeted cloud 
hosting services costs for the CAT Fee 2026-1 Period is reasonable.
---------------------------------------------------------------------------

    \45\ See chart entitled ``Comparison of Budgeted and Actual 
Costs for January & February 2026'' in Item II.A.1(2)(C) above.
---------------------------------------------------------------------------

(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. As this is the first Prospective CAT Fee filing under this CAT 
Funding Model, this filing describes the changes in the cloud hosting 
services costs from the Original 2026 Budget.\46\ Specifically, the 
following describes the differences in the costs for cloud hosting 
services included in the Original 2026 CAT Budget versus the Updated 
2026 CAT Budget, and the reasons for any changes.
---------------------------------------------------------------------------

    \46\ The last Prospective CAT Fee, CAT Fee 2025-2, was 
implemented pursuant to the prior CAT funding model. Moreover, the 
final invoice for CAT Fee 2025-2 was sent in December 2025, and, 
therefore, there is a six-month gap between the final invoice for 
CAT Fee 2025-2 and the first invoice for CAT Fee 2026-1, which would 
be in June 2026. Accordingly, this filing describes the changes in 
the cloud hosting services costs from the Original 2026 Budget.
---------------------------------------------------------------------------

    The annual 2026 budgeted costs for cloud hosting services included 
in the

[[Page 28070]]

Original 2026 CAT Budget were $81,900,006, and the annual 2026 budgeted 
costs for cloud hosting services included in the Updated 2026 CAT 
Budget are $77,529,362. Accordingly, budgeted annual costs for cloud 
hosting services decreased by $4,370,644 from the Original 2026 CAT 
Budget to the Updated 2026 CAT Budget, which is an approximate 5% 
reduction in cloud hosting services costs for the full year of 
2026.\47\ The budgeted decrease in costs for cloud hosting services 
reflects lower costs for January and February 2026 due to lower than 
forecasted market volumes in January and the impact of lower processing 
costs due to shutting down certain functionalities.

(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 $19,691,953 in technology costs for 
operating fees for the CAT Fee 2026-1 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 2026-1 Period, including the following:
    <bullet> 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;
    <bullet> Address compliance items, including drafting CAT policies 
and procedures, and addressing Regulation SCI requirements;
    <bullet> Provide support to the Operating Committee, the Compliance 
Subcommittee and CAT working groups;
    <bullet> Assist with interpretive efforts, exemptive requests and 
amendments regarding the CAT NMS Plan;
    <bullet> Oversee the security of the CAT;
    <bullet> Monitor the operation of the CAT, including with regard to 
Participant and Industry Member reporting;
    <bullet> Provide support to subcontractors under the Plan Processor 
Agreement;
    <bullet> Provide support in discussions with the Participants and 
the SEC and its staff;
    <bullet> Operate the FINRA CAT Helpdesk;
    <bullet> Facilitate communications with the industry, including via 
FAQs, CAT Alerts, meetings, presentations and webinars;
    <bullet> Administer the CAT website and all of its content;
    <bullet> Maintain cyber security insurance related to the CAT;
    <bullet> Assist with billing, collection and other CAT fee-related 
activity; and
    <bullet> 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 2026-1 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 2026-1 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 2026-1 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 2026-1 Period will be approximately 
$19,691,953.\48\ The budget for operating fees during the CAT Fee 2026-
1 Period is calculated based on the Updated 2026 CAT Budget. 
Specifically, this estimate was calculated by adding (1) two-thirds of 
the Non-CAIS fixed operating fees for the second quarter and the Non-
CAIS fixed operating fees for the third and fourth quarters of 2026 
included in the Updated 2026 CAT Budget and (2) two-thirds of the 
market data vendor fees for the second quarter and the market data 
vendor fees for the third and fourth quarter of 2026 included in the 
Updated 2026 CAT Budget.\49\
---------------------------------------------------------------------------

    \48\ See chart entitled ``Budgeted CAT Costs 2026-1'' in Item 
II.A.1(2)(C) above.
    \49\ This calculation is ((2/3 x $7,191,853) + $7,191,853 + 
$7,191,853) + ((2/3 x $192,630) + $192,630 + $192,630) = 
$19,691,953.
---------------------------------------------------------------------------

    As discussed above, CAT LLC estimated the budget for the operating 
fees during the CAT Fee 2026-1 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 2026-1 Period is the same process by 
which CAT LLC estimated the operating fees for the Original 2026 CAT 
Budget. The Original 2026 CAT Budget estimated a budget for operating 
fees of $5,149,236 for January and February 2026, and the actual costs 
for operating fees for January and February 2026 were $5,127,057. 
Therefore, the variance between budgeted and actual operating fees for 
this period was small--$22,179.\50\ Accordingly, CAT LLC believes that 
the process for estimating the budgeted operating fees for the CAT Fee 
2026-1 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 operating fees from the prior CAT Fee filing. As this 
is the first Prospective CAT Fee filing under this CAT Funding Model, 
this filing describes the changes in the operating fees from the 
Original 2026 Budget. Specifically, the following describes the 
differences in the costs for operating fees included in the Original 
2026 CAT Budget versus the Updated 2026 CAT Budget, and the reasons for 
any changes.
    The annual 2026 budgeted costs for operating fees included in the 
Original

[[Page 28071]]

2026 CAT Budget were $34,345,413, and the annual 2026 budgeted costs 
for operating fees included in the Updated 2026 CAT Budget are 
$29,845,524. Accordingly, budgeted annual costs for operating fees 
decreased by $4,499,889 from the Original 2026 CAT Budget to the 
Updated 2026 CAT Budget, which is an approximate 13% reduction in 
operating fees for the full year of 2026.\51\ The budgeted decrease in 
costs for operating fees reflects the proposed amendments to the Plan 
Processor Agreement related to the recent cost savings amendments to 
the CAT NMS Plan.\52\

(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 $14,179,060 in technology costs for CAIS 
operating fees for the CAT Fee 2026-1 Period. CAIS operating fees 
represent the fees paid to FCAT for services provided with regard to 
the operation and maintenance of the Reference Database (previously 
referred to as 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 Reference Data 
in the Reference Database and to create a CAT-Customer-ID for each 
Customer.\53\
---------------------------------------------------------------------------

    \53\ See Section 9 of Appendix D of the CAT NMS Plan.
---------------------------------------------------------------------------

    During the CAT Fee 2026-1 Period, it is anticipated that FCAT will 
provide services related to the Reference Database. Under the Plan 
Processor Agreement with FCAT, CAT LLC is required to pay FCAT for 
services related to the Reference Database provided by FCAT on a 
monthly basis. CAT LLC negotiated the fees for FCAT's services related 
to the Reference Database 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 2026-1 Period, it is anticipated that FCAT will 
continue to provide services relating to the ongoing operation, 
maintenance and support of the Reference Database.
    CAT LLC estimates that the budget for CAIS operating fees during 
the CAT Fee 2026-1 Period will be approximately $14,179,060.\54\ The 
budget for CAIS operating fees during the CAT Fee 2026-1 Period is 
calculated based on the Updated 2026 CAT Budget. Specifically, this 
estimate was calculated by adding two-thirds of the CAIS fixed 
operating fees for the second quarter and the CAIS fixed operating fees 
for the third and fourth quarters of 2026 included in the Updated 2026 
CAT Budget.\55\
---------------------------------------------------------------------------

    \54\ See chart entitled ``Budgeted CAT Costs 2026-1'' in Item 
II.A.1(2)(C) above.
    \55\ This calculation is (\2/3\ x $5,317,147) + $5,317,147 + 
$5,317,147 = $14,179,060.
---------------------------------------------------------------------------

    CAT LLC calculated the budget for FCAT's services related to the 
Reference Database for the CAT Fee 2026-1 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 2026-1 Period is the same process by which CAT LLC estimated 
the CAIS operating fees for the Original 2026 CAT Budget. The Original 
2026 CAT Budget estimated a budget of $3,544,764 for CAIS operating 
fees for January and February of 2026. The actual costs for CAIS 
operating fees for January and February of 2026, which are included in 
the Updated 2026 CAT Budget, were $3,544,764. There was no variance 
between budgeted and actual CAIS operating fees for the first two 
months of 2026.\56\ Accordingly, CAT LLC believes that the process for 
estimating the budgeted CAIS operating fees for the CAT Fee 2026-1 
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. As 
this is the first Prospective CAT Fee filing under this CAT Funding 
Model, this filing describes the changes in the CAIS operating fees 
from the Original 2026 Budget. Specifically, the following describes 
the differences in the costs for CAIS operating fees included in the 
Original 2026 CAT Budget versus the Updated 2026 CAT Budget, and the 
reasons for any changes.
    CAIS operating fees are based on a recurring monthly rate payable 
to FCAT and are unchanged from the Original 2026 CAT Budget to the 
Updated 2026 CAT Budget. The annual 2026 budgeted costs for CAIS 
operating fees included in the Original 2026 CAT Budget were 
$21,268,584, and the annual 2026 budgeted costs for CAIS operating fees 
included in the Updated 2026 CAT Budget are $21,268,590.\57\ 
Accordingly, the budgeted annual costs for CAIS operating fees are the 
same for both the Original 2026 CAT Budget and the Updated 2026 CAT 
Budget.

(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 $0 in technology costs for change 
request fees for the CAT Fee 2026-1 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.
    CAT LLC estimates that the budget for change requests during the 
CAT Fee 2026-1 Period will be approximately

[[Page 28072]]

$0.\58\ The budget for change requests during the CAT Fee 2026-1 Period 
is calculated based on the Updated 2026 CAT Budget. This $0 cost number 
for change request fees reflects the fact that there were no change 
request fees set forth in the Updated 2026 CAT Budget.
---------------------------------------------------------------------------

    \58\ See chart entitled ``Budgeted CAT Costs 2026-1'' in Item 
II.A.1(2)(C) above.
---------------------------------------------------------------------------

    CAT LLC estimated the budget for the potential change requests for 
the CAT Fee 2026-1 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 2026-1 Period is the same process 
by which CAT LLC estimated the change requests cost for the Original 
2026 CAT Budget. The Original 2026 CAT Budget estimated a change 
request budget of $0 for January and February of 2026. The actual costs 
for change requests for January and February of 2026, which are set 
forth in the Updated 2026 CAT Budget, were $0. There was no variance 
between budgeted and actual change request costs for January and 
February of 2026.\59\ Accordingly, CAT LLC believes that the process 
for estimating the budgeted change request costs for the CAT Fee 2026-1 
Period is reasonable.

(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 $3,450,000 in 
technology costs for capitalized developed technology costs for the CAT 
Fee 2026-1 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 the Reference Database 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 
related to the cost savings amendments \61\ and the move to 23x5 
trading.
---------------------------------------------------------------------------

    \61\ See CAIS Amendment and Cost Savings Amendment, supra note 
38.
---------------------------------------------------------------------------

    CAT LLC estimates that the budget for capitalized developed 
technology costs during the CAT Fee 2026-1 Period will be approximately 
$3,450,000.\62\ The budget for capitalized developed technology costs 
during the CAT Fee 2026-1 Period is calculated based on the Updated 
2026 CAT Budget. Specifically, this estimate was calculated by adding 
(1) capitalized developed technology costs of $3,450,000 for May, $0 
for June and $0 for the third and fourth quarters of 2026 included in 
the Updated 2026 CAT Budget; and (2) $0 for the Software License Fee 
2026 for the second, third, and fourth quarters of 2026 included in the 
Updated 2026 CAT Budget.\63\
---------------------------------------------------------------------------

    \62\ See chart entitled ``Budgeted CAT Costs 2026-1'' in Item 
II.A.1(2)(C) above.
    \63\ This calculation is ($3,450,000 + $0 + $0 + $0) + ($0 + $0 
+ $0) = $3,450,000. Note that the $4,178,964 cost for the software 
license fee was not included in the CAT Fee 2026-1 Period.
---------------------------------------------------------------------------

    CAT LLC estimated the budget for capitalized developed technology 
costs for the CAT Fee 2026-1 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 2026-1 Period is the same process by which CAT LLC 
estimated the capitalized developed technology costs for the Original 
2026 CAT Budget. The Original 2026 CAT Budget estimated a budget for 
capitalized developed technology costs of $671,472 for January and 
February 2026, and the actual costs for capitalized developed 
technology costs for January and February 2026 were $4,145,430.\64\ The 
variance of $3,473,958 for January and February 2026 is the result of 
costs related to the software license fee for the Reference Database 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 2026-1 Period is 
reasonable.

capitalized developed technology costs from the Original 2026 Budget. 
Specifically, the following describes the differences in the costs for 
capitalized developed technology costs as included in the Original 2026 
CAT Budget versus the Updated 2026 CAT Budget, and the reasons for any 
changes.
    The annual 2026 budget for capitalized developed technology costs 
included in the Original 2026 CAT Budget was $8,228,827, and the annual 
2026 budget for capitalized developed technology costs included in the 
Updated 2026 CAT Budget are $8,378,964.\65\ Accordingly, the annual 
budget for capitalized developed technology costs increased by $150,137 
from the Original 2026 CAT Budget to the Updated 2026 CAT Budget, which 
is an approximate 2% increase in the capitalized developed technology 
costs for the full year of 2026. This budgeted increase in the annual 
budget for capitalized developed technology costs was the result of 
costs related to the software license fee for the Reference Database in 
accordance with the Plan Processor Agreement with FCAT.

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 $5,670,452 in legal costs for the CAT Fee 2026-1 Period. This 
category of costs represents budgeted costs for legal services for this 
period. CAT LLC anticipates that it will receive legal services from

Fee 2026-1 Period.
    Law Firm: WilmerHale. It is anticipated that legal costs during the 
CAT Fee 2026-1 Period will include costs related to the legal services 
performed by WilmerHale. CAT LLC anticipates that it will continue to

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

    CAT LLC estimated the budget for the legal costs for WilmerHale for 
the CAT Fee 2026-1 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.
    Law Firm: Jenner. It is anticipated that legal costs during the CAT 
Fee 2026-1 Period will include costs related to the legal services

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.\69\ 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. Jenner 
also will continue to provide legal counseling to CAT LLC related to 
the above-listed litigation and other litigation risk.

    CAT LLC estimated the budget for the legal costs for Jenner for the 
CAT Fee 2026-1 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 2026-1 Period will be approximately 
$5,670,452.\70\ The budget for legal services during the CAT Fee 2026-1 
Period is calculated based on the Updated 2026 CAT Budget. 
Specifically, this estimate was calculated by adding budgeted costs for 
two-thirds of the legal costs for the second quarter and the legal 
costs for the third and fourth quarters of 2026 included in the Updated 
2026 CAT Budget.\71\
---------------------------------------------------------------------------

    CAT LLC estimated the budget for the legal services for the CAT Fee 
2026-1 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 2026-1 
Period is the same process by which CAT LLC estimated the legal cost 
for the Original 2026 CAT Budget. The Original 2026 CAT Budget 
estimated a budget for legal costs of $1,424,166 for January and 
February of 2026. The actual costs for legal services for January and 
February 2026, which are included in the Updated 2026 Budget, were 
$1,838,617.\72\ The increase of $414,451 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 related to litigation matters as 
well as regulatory and corporate legal matters. Accordingly, CAT LLC 
believes that the process for estimating the

budgeted legal costs for the CAT Fee 2026-1 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. As this is 
the first Prospective CAT Fee filing under this CAT Funding Model, this 
filing describes the changes in the legal costs from the Original 2026 
Budget. Specifically, the following describes the differences in the 
legal costs included in the Original 2026 CAT Budget versus the Updated 
2026 CAT Budget, and the reasons for any changes.
    The annual 2026 budgeted legal costs included in the Original 2026 
CAT Budget were $8,485,000, and the annual 2026 budgeted legal costs 
included in the Updated 2026 CAT Budget are $8,939,184.\73\ 
Accordingly, the annual budget for legal costs increased by $454,184 
from the Original 2026 CAT Budget to the Updated 2026 CAT Budget for 
the full year of 2026, which is an approximate 5% increase in the legal 
costs for the full year of 2026. This budgeted increase in the legal 
costs in the Updated 2026 CAT Budget from the Original 2026 Budget 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 $1,025,957 in consulting costs for the 
CAT Fee 2026-1 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 2026-1 Period. The 
services provided by Deloitte to the CAT include advisory services 
related to the operation of the CAT, and meeting facilitation and 
communications coordination, vendor support and financial analyses. In 
addition, the consulting costs include the compensation for the Chair 
of the CAT Operating Committee.
    It is anticipated that the costs for CAT during the CAT Fee 2026-1 
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 2026-1 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 2026-1 Period, 
including the following:
    <bullet> Implement program operations for the CAT project;
    <bullet> 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;
    <bullet> Assist with cost and funding matters for the CAT, 
including assistance with loans and the CAT bank account for CAT 
funding;
    <bullet> Provide support for updating the SEC on the progress of 
the development of the CAT; and
    <bullet> 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, which is paid by CAT LLC.
    CAT LLC estimates that the budget for consulting costs during the 
CAT Fee 2026-1 Period will be approximately $1,025,957.\74\ The budget 
for consulting costs during the CAT Fee 2026-1 Period is calculated 
based on the Updated 2026 CAT Budget. Specifically, this estimate was 
calculated by adding two-thirds of the consulting costs for the second 
quarter and the consulting costs for the third and fourth quarters of 
2026 included in the Updated 2026 CAT Budget.\75\
---------------------------------------------------------------------------

$2,115,170 = $5,670,452.
---------------------------------------------------------------------------

    CAT LLC estimates the budget for the consulting costs for Deloitte 
for the CAT Fee 2026-1 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, and discussions with Deloitte, as well as the 
compensation arrangement for the Chair. This process for estimating the 
budget for consulting costs for the CAT Fee 2026-1 Period is the same 
process by which CAT LLC estimated the consulting costs for the 
Original 2026 CAT Budget. The Original 2026 CAT Budget estimated a 
budget for consulting services of $258,334 for January and February 
2026, and the actual costs for consulting services for January and 
February 2026, which are included in the Updated 2026 CAT Budget, were 
$267,554.\76\ Therefore, the variance between budgeted and actual 
consulting costs for January and February was approximately 4%. 
Accordingly, CAT LLC believes that the process for estimating the 
budgeted consulting costs for the CAT Fee 2026-1 Period is reasonable.

differences (if any) in the consulting costs included in the Original 
2026 CAT Budget versus the Updated 2026 CAT Budget, and the reasons for 
any changes.
    The annual 2026 budget for consulting costs included in the 
Original 2026 CAT Budget was $1,550,000, and the annual 2026 budget for 
consulting costs included in the Updated 2026 CAT Budget is 
$1,550,000.\77\ Accordingly, the annual budget for consulting costs has 
not changed from the Original 2026 CAT Budget to the Updated 2026 CAT 
Budget for the full year of 2026.

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

    It is anticipated that the insurance costs for CAT during the CAT 
Fee 2026-1 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 2026-1 Period, and notes that the annual 
premiums for these policies were competitive for the coverage provided. 
CAT LLC estimated the budget for the insurance costs for the CAT Fee 
2026-1 Period based on the insurance estimate from USI for 2026. The 
annual premiums would be paid by CAT LLC to USI.
    The budgeted insurance costs for the CAT Fee 2026-1 Period are 
based on an insurance cost estimate from USI for 2026. Accordingly, CAT 
LLC believes that the process for estimating the budgeted insurance 
costs for the CAT Fee 2026-1 Period is reasonable.
(b) Changes From Prior Fee Filing
    Section 11.3(a)(iii)(B)(B) of the CAT NMS Plan requires the fee

differences in the insurance costs included in the Original 2026 CAT 
Budget versus the Updated 2026 CAT Budget, and the reasons for any 
changes.
    The annual 2026 budgeted insurance costs included in the Original 
2026 CAT Budget were $1,505,625, and the annual 2026 budgeted insurance 
costs included in the Updated 2026 CAT Budget are $1,254,070.\79\ 
Accordingly, the annual budget for insurance costs decreased by 
$251,555 from the Original 2026 CAT Budget to the Updated 2026 CAT 
Budget for the full year of 2026, which is an approximate 16% decrease 
in the insurance costs for the full year of 2026. This budgeted 
decrease in the insurance costs in the Updated 2026 CAT Budget from the 
Original 2026 Budget was primarily due to an anticipated decrease in 
insurance premiums.

    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 $749,151 in 
professional and administration costs for the CAT Fee 2026-1 Period. In 
adopting the CAT NMS Plan, the Commission amended the Plan to add a 
requirement that CAT LLC's financial statements be prepared in 
compliance with GAAP, audited by an independent public accounting firm, 
and made publicly available.\80\ 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 
to be paid to Anchin, Block & Anchin (``Anchin'') and Grant Thornton 
LLP (``Grant Thornton'') for financial services during the CAT Fee 
2026-1 Period.
---------------------------------------------------------------------------

    \80\ See Section 9.2 of the CAT NMS Plan.
---------------------------------------------------------------------------

    Financial Advisory Firm: Anchin. It is anticipated that the 
professional and administration costs for the CAT Fee 2026-1 Period 
will include costs related to financial advisory services performed by 
Anchin. CAT LLC anticipates that it will continue to employ Anchin 
during the CAT Fee 2026-1 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

    <bullet> Review historical costs from inception;
    <bullet> Provide accounting and financial information in support of 
SEC filings; and
    <bullet> Perform additional ad hoc accounting and financial 
advisory services, as requested by CAT LLC.
    CAT LLC estimated the annual budget for the costs for Anchin based 
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 2026-1 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 2026-1 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

[[Page 28076]]

the requirements of the CAT NMS Plan. The fees for these services will 
be paid by CAT LLC to Grant Thornton. CAT LLC estimated the budget for 
the accounting costs for Grant Thornton for the CAT Fee 2026-1 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 2026-1 Period will be approximately $749,151.\81\ The budget 
for professional and administration services during the CAT Fee 2026-1 
Period is based on the Updated 2026 CAT Budget. CAT LLC estimated the 
budget for the professional and administration costs for the CAT Fee 
2026-1 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 2026-1 
Period is the same process by which CAT LLC estimated the professional 
and administration costs for the Original 2026 CAT Budget. The Original 
2026 CAT Budget estimated a budget for professional and administration 
costs of $190,916 for January and February 2026, and the actual costs 
for professional and administration services for January and February 
2026, which are set forth in the Updated 2026 Budget, were 
$149,061.\82\ The decrease of $41,855 was due to a lower than expected 
professional and administration services costs and to the movement of 
bank fees from the professional and administration category to the 
interest income category. Accordingly, CAT LLC believes that the 
process for estimating the budgeted professional and administration 
costs for the CAT Fee 2026-1 Period is reasonable.

the line item for professional and administration costs from the prior 
CAT Fee filing. As this is the first Prospective CAT Fee filing under 
this CAT Funding Model, this filing describes the changes in the 
professional and administration costs from the Original 2026 Budget. 
Specifically, the following describes the differences in the 
professional and administration costs included in the Original 2026 CAT 
Budget versus the Updated 2026 CAT Budget, and the reasons for any 
changes.
    The annual 2026 budgeted professional and administration costs as 
included in the Original 2026 CAT Budget were $1,145,500, and the 
annual 2026 budgeted professional and administration costs included in 
the Updated 2026 CAT Budget are $1,085,500.\83\ Accordingly, the 
budgeted annual costs for professional and administration services 
decreased by $60,000 from the Original 2026 CAT Budget to the Updated 
2026 CAT Budget for the full year of 2026. This budgeted decrease in 
the professional and administration costs in the Updated 2026 CAT 
Budget from the Original 2026 Budget was due to the movement of bank 
fees from the professional and administration category to the interest 
income category, and not a change in costs related to Anchin and Grant 
Thornton services.

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 2026-1 Period. The public relations costs would 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 CAT Fee Period 2026-1, the budget for public 
relations costs for this period is $0.\84\

Original 2026 CAT Budget were $0, and the annual budgeted public 
relations costs for 2026 included in the Updated 2026 CAT Budget are

include ``the sources of all revenues to cover costs.'' Accordingly, 
the Updated 2026 CAT Budget includes a line item for interest income. 
Specifically, the Operating Committee approved an operating budget for 
the CAT pursuant to Section 11.1(a) of the CAT NMS Plan that included 
$1,453,382 in interest income for the CAT Fee 2026-1 Period.\86\ 
Interest income represents the interest earned on the surplus reserve 
and other funds held by CAT LLC. Such income would be used to reduce 
the amount to be collected to fund the CAT.
---------------------------------------------------------------------------

    \86\ See chart entitled ``Budgeted CAT Costs 2026-1'' in Item 
II.A.1(2)(C) above.
---------------------------------------------------------------------------

    CAT LLC estimates the budget for the interest income for the CAT 
Fee 2026-1 Period based on the estimate of the funds held by CAT LLC 
and the expected interest rates on such funds. The Original 2026 CAT 
Budget estimated interest income of $758,343 for January and February 
2026, and the actual interest income for January and February 2026, 
which are included in the Updated 2026 CAT Budget, were $757,527.\87\ 
As mentioned above, bank fees were moved from the professional and 
administration category in the Original 2026 CAT Budget to the interest 
income category in the Updated 2026 CAT Budget. Accordingly, the 
interest income amount for the Updated 2026 CAT Budget was net of 
$10,000 in bank fees. Therefore, the variance between budgeted and 
actual interest income (aside from bank fees) for January and February 
2026 was approximately $10,000. Accordingly, CAT LLC believes that the 
process for

[[Page 28077]]

estimating the budgeted interest income for the CAT Fee 2026-1 Period 
is reasonable.
---------------------------------------------------------------------------

    \87\ See chart entitled ``Comparison of Budgeted and Actual 
Costs for January & February 2026'' in Item II.A.1(2)(C) above.
---------------------------------------------------------------------------

(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 
each line item from the prior CAT Fee filing. As this is the first 
Prospective CAT Fee filing under this CAT Funding Model, this filing 
describes the changes in interest income from the Original 2026 CAT 
Budget. Specifically, the following describes the differences in the 
interest income included in the Original 2026 CAT Budget versus the 
Updated 2026 CAT Budget, and the reasons for any changes.
    The annual 2026 budgeted interest income as included in the 
Original 2026 CAT Budget was $1,995,958, and the annual 2026 budgeted 
interest income included in the Updated 2026 CAT Budget is 
$2,806,325.\88\ Accordingly, the budgeted interest income (not 
including bank fees) increased by $810,367 from the Original 2026 CAT 
Budget to the Updated 2026 CAT Budget for the full year of 2026, which 
is an approximate 40% increase in the interest income for the full year 
of 2026. This budgeted increase in the interest income in the Updated 
2026 CAT Budget from the Original 2026 Budget was primarily due to 
higher than expected cash balances being maintained after the approval 
of the Original 2026 Budget.
---------------------------------------------------------------------------

    \88\ See chart entitled ``Comparison of Full Year Budgeted 
Costs'' in Item II.A.1(2)(C) above.
---------------------------------------------------------------------------

(xii) 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 2026. 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 the Updated 2026 CAT Budget (which does 
not include the reserve amount). Accordingly, the total 25% reserve of 
$23,508,157 was calculated by multiplying the total expenses set forth 
in the Updated 2026 CAT Budget (other than the reserve) by 25%.\89\
---------------------------------------------------------------------------

    \89\ The reserve was calculated by multiplying $94,032,626 by 
25%, which equals approximately $23,508,157.
---------------------------------------------------------------------------

    The Updated 2026 CAT Budget estimates that CAT LLC will have 
$102,391,135 in reserve as of the beginning of the CAT Fee Period 2026-
1. Such reserve is related, in part, to (i) the collection of CAT fees 
in excess of the budgeted CAT costs in light of the greater actual 
executed equivalent share volume than the projected executed equivalent 
share volume for prior CAT Fees, and (ii) a reduction in anticipated 
budgeted costs associated with the implementation of certain cost 
savings measures. This reserve balance of $102,391,135 would be used to 
offset a portion of CAT costs for CAT Fee Period 2026-1, thereby 
reducing the fee rate to be paid for CAT Fee 2026-1. Specifically, the 
total costs (including the 25% reserve) for CAT Fee 2026-1 of 
$117,540,783 would be reduced by the $102,391,135 in reserve. 
Therefore, the Total Budgeted CAT Costs 2026-1 would be $15,149,648.
    Accordingly, the fee rate for CAT Fee 2026-1 is calculated based on 
this reduced amount of $15,149,648, resulting in a fee rate of 
$0.000001 per executed equivalent share. If the fee rate for CAT Fee 
2026-1 were calculated solely based on the reasonably budgeted costs 
for CAT for May-December 2026, excluding the reduction in that amount 
due to the surplus reserve offset, the fee rate would be the higher 
rate of $0.000010.\90\
---------------------------------------------------------------------------

    \90\ See CAT Fee Alert 2026-1 (April 1, 2026), <a href="https://www.catnmsplan.com/sites/default/files-2026-04/04.01.26-CAT-Fee-Alert-2026-1.pdf">https://www.catnmsplan.com/sites/default/files-2026-04/04.01.26-CAT-Fee-Alert-2026-1.pdf</a>.
---------------------------------------------------------------------------

(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. As this is 
the first Prospective CAT Fee filing under this CAT Funding Model, this 
filing describes the changes in reserve from the Original 2026 CAT 
Budget. Specifically, the following describes the differences in the 
reserve included in the Original 2026 CAT Budget versus the Updated 
2026 CAT Budget, and the reasons for any changes.
    The accrued liquidity reserve balance at the beginning of the year 
included in the Original 2026 CAT Budget was $119,128,336. The Original 
2026 CAT Budget contemplated using the reserve to pay CAT bills 
throughout the year as no CAT fee was in effect. The accrued liquidity 
reserve balance at the beginning of the year included in the Updated 
2026 CAT Budget was $155,403,378. The increase in the accrued liquidity 
reserve balance at the beginning of the year from the Original 2026 CAT 
Budget to the Updated 2026 CAT Budget reflected the additional CAT Fees 
that had been received after the approval of the Original 2026 CAT 
Budget. In addition, the Updated 2026 CAT Budget not only reflected the 
use of the surplus reserve to pay CAT bills but also the accrual of 
additional reserve to establish a 25% reserve through CAT Fee 2026-1. 
Accordingly, the estimated liquidity reserve balance increased from a 
deficit of $37,304,661 included in the Original 2026 CAT Budget to a 
reserve balance of $23,508,157 included in the Updated 2026 CAT Budget 
for the full year of 2026.
(D) Projected Total Executed Equivalent Share Volume
    The calculation of Fee Rate 2026-1 also requires the determination 
of the projected total executed equivalent share volume of transactions 
in Eligible Securities for the CAT Fee 2026-1 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.'' \91\ 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.\92\
---------------------------------------------------------------------------

    \91\ See Section 11.3(a)(i)(D) of the CAT NMS Plan.
    \92\ See CAT Funding Model Approval Order, 91 FR 13410, 13452.
---------------------------------------------------------------------------

    The total executed equivalent share volume of transactions in 
Eligible

[[Page 28078]]

Securities for the 12-month period from March 2025 through February 
2026 was 5,980,937,549,360.49 executed equivalent shares. The Operating 
Committee has determined to calculate the projected total executed 
equivalent share volume for the eight-month recovery period for CAT Fee 
2026-1 by multiplying by 8/12ths the executed equivalent share volume 
for the 12-month period from March 2025 through February 2026. The 
Operating Committee determined that such an approach was reasonable as 
the CAT's annual executed equivalent share volume has increased from 
prior years (e.g., the executed equivalent share volume for 2024 was 
4,295,884,600,069.41), and the Operating Committee believes that it is 
reasonable to conclude that the annual executed equivalent share volume 
will remain at the higher level. Accordingly, the projected total 
executed equivalent share volume for the eight-month period for CAT Fee 
2026-1 is projected to be 3,987,291,699,573.66 executed equivalent 
shares.\93\
---------------------------------------------------------------------------

    \93\ This projection was calculated by multiplying 
5,980,937,549,360.49 executed equivalent shares by 8/12ths.
---------------------------------------------------------------------------

    The projected total executed equivalent share volume of all 
transactions in Eligible Securities for the eight-month recovery period 
for CAT Fee 2026-1 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.\94\
---------------------------------------------------------------------------

    \94\ See Section 11.3(a)(iii)(B) of the CAT NMS Plan.
---------------------------------------------------------------------------

(E) Fee Rate 2026-1
    Fee Rate 2026-1 would be calculated by dividing the Budgeted CAT 
Costs 2026-1 by the reasonably projected total executed equivalent 
share volume of all transactions in Eligible Securities for the eight-
month recovery period for CAT Fee 2026-1, as described in detail 
above.\95\ Specifically, Fee Rate 2026-1 would be calculated by 
dividing $15,149,648 by 3,987,291,699,573.66 executed equivalent 
shares. As a result, Fee Rate 2026-1 would be $0.000003799483243631228 
per executed equivalent share. Fee Rate 2026-1 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.\96\
---------------------------------------------------------------------------

    \95\ 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 appropriate.'' See CAT Funding Model 
Approval Order, 91 FR 13410, 13435.
    \96\ See Section 11.3(a)(iii)(B)(A) of the CAT NMS Plan.
---------------------------------------------------------------------------

    Fee Rate 2026-1 would be used to calculate the fee rate to be paid 
by CEBSs and CEBBs for CAT Fee 2026-1. Such fee rate is calculated by 
multiplying Fee Rate 2026-1 of $0.000003799483243631228 by one-third, 
and rounding the result to six decimal places.\97\ Accordingly, the fee 
rate to be paid by CEBSs and CEBBs for CAT Fee 2026-1 would be 
$0.000001 per executed equivalent share.
---------------------------------------------------------------------------

    \97\ This fee rate of $0.000001 is calculated by multiplying the 
Fee Rate of $0.000003799483243631228 by one-third and rounding this 
result (which equals $0.000001266494414543743) to 6 decimal places.
---------------------------------------------------------------------------

(3) Monthly Fees
    CEBBs and CEBSs would be required to pay fees for CAT Fee 2026-1 on 
a monthly basis for eight months, from July 2026 until January 2027. 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.\98\ Proposed paragraph (a)(1)(F)(i) of Rule 6897 would 
state that each CAT Executing Broker would receive its first invoice 
for CAT Fee 2026-1 in June 2026, and would receive an invoice for CAT 
Fee 2026-1 each month thereafter until January 2027. Proposed paragraph 
(a)(1)(F)(ii) of Rule 6897 would state that ``Consolidated Audited 
Trail, LLC shall provide each CAT Executing Broker with an invoice for 
CAT Fee 2026-1 on a monthly basis.'' In addition, paragraph (a)(2)(A) 
of Rule 6897 states that each CEBB and CEBS is required to pay its CAT 
fees ``each month.''
---------------------------------------------------------------------------

    \98\ See proposed paragraph (a)(1)(F)(ii) of FINRA Rule 6897.
---------------------------------------------------------------------------

(4) Consolidated Audit Trail Funding Fees
    To implement CAT Fee 2026-1, FINRA proposes to add a new paragraph 
to the FINRA Rule 6897 (Consolidated Audit Trail Funding Fees), to 
include the proposed paragraphs described below.
(A) CAT Fee 2026-1
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.\99\
---------------------------------------------------------------------------

    \99\ See Section 11.3(a)(iii)(A) of the CAT NMS Plan.

    Accordingly, based on the factors discussed above, FINRA proposes 
---------------------------------------------------------------------------
to add paragraph (a)(1)(F) to FINRA Rule 6897, which would state that:

    (i) Each CAT Executing Broker shall receive its first invoice 
for CAT Fee 2026-1 in June 2026, which shall set forth the CAT Fee 
2026-1 fees calculated based on transactions in May 2026, and shall 
receive an invoice for CAT Fee 2026-1 for each month thereafter 
until January 2027.
    (ii) Consolidated Audit Trail, LLC shall provide each CAT 
Executing Broker with an invoice for CAT Fee 2026-1 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 $0.000001 per executed equivalent share.
    (iii) Notwithstanding the last invoice date of January 2027 for 
CAT Fee 2026-1 in paragraph (a)(1)(F)(i) of this Rule, CAT Fee 2026-
1 shall continue in effect after January 2027, with each CAT 
Executing Broker receiving an invoice for CAT Fee 2026-1 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 2026-
1 will no longer be in effect.
    (iv) Each CAT Executing Broker shall be required to pay each 
invoice for CAT Fee 2026-1 in accordance with paragraph (a)(2) of 
this Rule.

    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.'' \100\ Accordingly, proposed paragraph 
(a)(1)(F)(ii) of Rule 6897 would set forth a fee rate of $0.000001 per 
executed equivalent share. This fee rate is calculated by multiplying 
Fee Rate 2026-1 of $0.000003799483243631228 by one-

[[Page 28079]]

third, and rounding the result to six decimal places.\101\ 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.
---------------------------------------------------------------------------

    \100\ See CAT Funding Model Approval Order, 91 FR 13410, 13445 
n.677.
    \101\ This fee rate of $0.000001 is calculated by multiplying 
the Fee Rate of $0.000003799483243631228 by one-third, and rounding 
this result (which equals $0.000001266494414543743) to 6 decimal 
places.
---------------------------------------------------------------------------

    The proposed language in paragraph (a)(1)(F)(i) of Rule 6897 would 
describe when CAT Executing Brokers would receive their first monthly 
invoice for CAT Fee 2026-1. Specifically, CAT Executing Brokers would 
receive their first monthly invoice for CAT Fee 2026-1 in June 2026 and 
the fees set forth in that invoice would be calculated based on 
transactions executed in May 2026. 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 
(a)(2)(B) of Rule 6897.
    Proposed paragraph (a)(1)(F)(i) of Rule 6897 also would describe 
the monthly cadence of the invoices for CAT Fee 2026-1. Specifically, 
after the first invoices are provided to CAT Executing Brokers in June 
2026, invoices will be sent to CAT Executing Brokers each month 
thereafter until January 2027.
    Proposed paragraph (a)(1)(F)(ii) of Rule 6897 would describe the 
invoices for CAT Fee 2026-1. Proposed paragraph (a)(1)(F)(ii) of Rule 
6897 would state that ``Consolidated Audit Trail, LLC shall provide 
each CAT Executing Broker with an invoice for CAT Fee 2026-1 on a 
monthly basis.'' Proposed paragraph (a)(1)(F)(ii) of Rule 6897 also 
would describe the fees to be set forth in the invoices for CAT Fee 
2026-1. 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 $0.000001 per executed equivalent share.''
    Since CAT Fee 2026-1 is a monthly fee based on actual transaction 
volume from the prior month, CAT Fee 2026-1 may collect more or less 
than two-thirds of the Budgeted CAT Costs 2026-1. To the extent that 
CAT Fee 2026-1 collects more than two-thirds of the Budgeted CAT Costs 
2026-1, 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 
2026-1 collects less than two-thirds of the Budgeted CAT Costs 2026-1, 
the budget for the CAT in the ensuing months will reflect such 
shortfall.
    Furthermore, proposed paragraph (a)(1)(F)(iii) of Rule 6897 would 
describe how long CAT Fee 2026-1 would remain in effect. It would state 
that ``[n]otwithstanding the last invoice date of January 2027 for CAT 
Fee 2026-1 in paragraph (a)(1)(F)(i) of this Rule, CAT Fee 2026-1 shall 
continue in effect after January 2027, with each CAT Executing Broker 
receiving an invoice for CAT Fee 2026-1 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 2026-1 will no longer be in 
effect.''
    Finally, proposed paragraph (a)(1)(F)(iv) of Rule 6897 would set 
forth the requirement for the CAT Executing Brokers to pay the invoices 
for CAT Fee 2026-1. It would state that ``[e]ach CAT Executing Broker 
shall be required to pay each invoice for CAT Fee 2026-1 in accordance 
with paragraph (a)(2) of this Rule.''
(B) Manner of Payment
    Paragraph (a)(2)(A) of Rule 6897 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)(1) of this 
Rule 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.\102\ The Plan Processor has established a 
billing system for CAT fees.\103\ Accordingly, CAT Executing Brokers 
would be required to pay CAT Fee 2026-1 in accordance with such system.
---------------------------------------------------------------------------

    \102\ See Section 11.4 of the CAT NMS Plan.
    \103\ The billing process and system are described in CAT Alert 
2023-02 as well as in 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.\104\
---------------------------------------------------------------------------

    \104\ See Section 11.4 of the CAT NMS Plan.

---------------------------------------------------------------------------
    Accordingly, Paragraph (a)(2)(B) of Rule 6897 states that:

    Each CAT Executing Broker shall pay the CAT fees required 
pursuant to paragraph (a)(1) of this Rule within 30 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 (a)(2) would apply to CAT Fee 2026-1.
(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.\105\
---------------------------------------------------------------------------

    \105\ See 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.\106\ 
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.
---------------------------------------------------------------------------

    \106\ 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.'' See CAT Funding Model 
Approval Order, 91 FR 13410, 13454.
---------------------------------------------------------------------------

    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

[[Page 28080]]

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.'' \107\ Such aggregate statistics will be available on 
the CAT website.
---------------------------------------------------------------------------

    \107\ See 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.'' See CAT Funding Model Approval Order, 91 FR 13410, 13454.
---------------------------------------------------------------------------

    Furthermore, CAT LLC will make publicly available on the CAT 
website the total amount invoiced each month that CAT Fee 2026-1 is in 
effect as well as the total amount invoiced for CAT Fee 2026-1 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 2026-1.
(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.'' \108\ 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,\109\ 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.\110\

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

(7) Participant Invoices
    While CAT Fees charged to Industry Members become effective in 
accordance with the requirements of Section 19(b) of the Exchange 
Act,\111\ 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.\112\ On March 31, 2026, the 
Operating Committee approved the Participant fee related to CAT Fee 
2026-1. Specifically, pursuant to the requirements of CAT NMS 
Plan,\113\ each Participant would be required to pay a CAT fee 
calculated using the fee rate of $0.000001 per executed equivalent 
share, which is the same fee rate that applies to CEBBs and CEBSs. Like 
CEBBs and CEBSs, each Participant would be invoiced such CAT fees on a 
monthly basis for eight months, from June 2026 until January 2027, 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 June 2026, and would receive an invoice each month 
thereafter until January 2027. Like with the CAT Fee 2026-1 applicable 
to CEBBs and CEBSs as described in proposed paragraph (a)(1)(F)(iii) of 
Rule 6897, notwithstanding the last invoice date of January 2027, 
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
---------------------------------------------------------------------------

    \111\ See Section 11.3(a)(i)(A)(I) of the CAT NMS Plan.
    \112\ See CAT Funding Model Approval Order, 91 FR 13410, 13448.
    \113\ 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.

    FINRA has filed the proposed rule change for immediate 
effectiveness. The effective date and the implementation date will be 
the date of filing.
2. Statutory Basis
    FINRA believes that the proposed rule change is consistent with 
Section 15A(b)(6) of the Act,\114\ which requires, among other things, 
that FINRA rules 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. FINRA also believes that the proposed rule change 
is consistent with the provisions of Section 15A(b)(5) of the Act,\115\ 
which requires, among other things, that FINRA rules provide for the 
equitable allocation of reasonable dues, fees and other charges among 
members and issuers and other persons using any facility or system that 
FINRA operates or controls. FINRA further believes that the proposed 
rule change is consistent with Section 15A(b)(9) of the Act,\116\ which 
requires that FINRA rules not impose any burden on competition that is 
not necessary or appropriate. Section 15A(b)(2) of the Act \117\ also 
requires that FINRA 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. Accordingly, a 
reasonable reading of the Act indicates that it intended that 
regulatory funding be sufficient to permit FINRA 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 any facility or system that FINRA operates 
or controls.

    \117\ 15 U.S.C 78o-3(b)(2).
---------------------------------------------------------------------------

    FINRA believes that this proposed rule change is consistent with 
the Act because it implements provisions of the Plan and is designed to 
assist FINRA 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.'' \118\ To the extent that 
this proposed rule change implements the Plan and applies

[[Page 28081]]

specific requirements to Industry Members, FINRA believes that this 
proposed rule change furthers the objectives of the Plan, as identified 
by the SEC, and is therefore consistent with the Act.
---------------------------------------------------------------------------

    \118\ See CAT NMS Plan Approval Order, 81 FR 84696, 84697.
---------------------------------------------------------------------------

    FINRA also believes that the proposed fees to be paid by the CEBBs 
and CEBSs are reasonable, equitably allocated and not unfairly 
discriminatory.
    The proposed CAT Fee 2026-1 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. The proposed fees would not cover FINRA services unrelated to 
the CAT. In addition, any surplus would be used as a reserve to offset 
future fees.
    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. Thus, FINRA 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, FINRA 
has filed this fee filing to implement the Industry Member CAT fees 
included in the CAT Funding Model. FINRA believes that this proposed 
rule change 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 FINRA 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.'' \119\ Similarly, 
in approving the CAT Funding Model, the SEC concluded that the CAT 
Funding Model met this standard.\120\ As this proposed rule change 
implements the Plan and the CAT Funding Model described therein, and 
applies specific requirements to Industry Members in compliance with 
the Plan, FINRA believes that this proposed rule change furthers the 
objectives of the Plan, as identified by the SEC, and is therefore 
consistent with the Exchange Act.
---------------------------------------------------------------------------

    \119\ See supra note 118.
    \120\ See CAT Funding Model Approval Order, 91 FR 13410, 13481.
---------------------------------------------------------------------------

(2) Calculation of Fee Rate for CAT Fee 2026-1 Is Reasonable
    The SEC has determined that the CAT Funding Model 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, satisfies the 
Exchange Act.\121\ In each respect, as discussed above, CAT Fee 2026-1 
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, FINRA believes that each of the 
figures for the variables in the SEC-approved formula for calculating 
the fee rate for CAT Fee 2026-1 is reasonable and consistent with the 
Exchange Act. The calculation of Fee Rate 2026-1 for CAT Fee 2026-1 
requires the figures for Budgeted CAT Costs 2026-1, the executed 
equivalent share volume for the prior twelve months, the determination 
of the CAT Fee 2026-1 Period, and the projection of the executed 
equivalent share volume for the CAT Fee 2026-1 Period. Each of these 
variables is reasonable and satisfies the Exchange Act, as discussed 
throughout this filing.
---------------------------------------------------------------------------

    \121\ See supra note 120.
---------------------------------------------------------------------------

(A) Budgeted CAT Costs 2026-1
    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, FINRA has set forth the amount 
and type of Budgeted CAT Costs 2026-1 for each of the 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, FINRA believes that the budget 
for the CAT Fee 2026-1 Period is ``reasonable and appropriate.'' Each 
of the costs included in CAT Fee 2026-1 is 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 is 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.\122\ 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 2026-1. 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.\123\ 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

[[Page 28082]]

CAT than anticipated when Rule 613 was originally adopted.
---------------------------------------------------------------------------

    \122\ See Section 11.3(a)(iii)(B)(B)(1) of the CAT NMS Plan.
    \123\ For a discussion of the amount and type of cloud hosting 
services fees, see Item II.A.1(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 
\124\ and that annual operating costs for the CAT would range from 
$36.5 million to $55 million.\125\ In contrast to the 2016 projections, 
the actual daily Q3 2025 data volumes averaged 792 billion events per 
day.
---------------------------------------------------------------------------

    \124\ See Section 1.3 of Appendix D-4 of the CAT NMS Plan at 
n.262.
    \125\ See CAT NMS Plan Approval Order, 81 FR 84696, 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.
    The reasonableness of the cloud hosting services costs is further 
supported by key cost discipline mechanisms for the CAT--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.\126\
---------------------------------------------------------------------------

    \126\ See Securities Exchange Act Release No. 97151 (March 15, 
2023), 88 FR 17086, 17117 (March 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.\127\ 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 2026-1.
---------------------------------------------------------------------------

    \127\ See 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.\128\ 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.\129\ The services to be 
performed by FCAT for CAT Fee 2026-1 Period and the budgeted costs 
related to such services are described above.\130\
---------------------------------------------------------------------------

    \128\ See Item II.A.1(2)(C)(ii) above.
    \129\ See supra note 128.
    \130\ See supra note 128.
---------------------------------------------------------------------------

    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 2026-1 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.\131\
---------------------------------------------------------------------------

    \131\ See supra note 128.
---------------------------------------------------------------------------

(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.\132\ 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 2026-1. The 
CAIS operating fees would include the fees paid to the Plan Processor 
to operate and maintain the Reference Database 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 
services related to the Reference Database, 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.\133\ The services to be performed by FCAT for the CAT Fee 
2026-1 Period and the budgeted costs for such services are described 
above.\134\
---------------------------------------------------------------------------

    \132\ See Section 11.3(a)(iii)(B)(B)(1) of the CAT NMS Plan.
    \133\ See Item II.A.1(2)(C)(iii) above.
    \134\ See supra note 133.
---------------------------------------------------------------------------

(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.\135\ 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 2026-1. It 
is common practice to utilize a change request process to address

[[Page 28083]]

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,\136\ CAT LLC determined that it was 
reasonable not to include any change request fees in the Budgeted CAT 
Costs 2026-1.
---------------------------------------------------------------------------

    \135\ See Section 11.3(a)(iii)(B)(B)(1) of the CAT NMS Plan.
    \136\ See Item II.A.1(2)(C)(iv) above.
---------------------------------------------------------------------------

(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.\137\ 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 and license fees. The amount and 
type of budgeted capitalized developed technology costs for the CAT Fee 
2026-1 Period, which relate to the software license fee and technology 
changes to be implemented by FCAT, are described in more detail 
above.\138\
---------------------------------------------------------------------------

    \137\ See Section 11.3(a)(iii)(B)(B)(1) of the CAT NMS Plan.
    \138\ See Item II.A.1(2)(C)(v) above.
---------------------------------------------------------------------------

(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.\139\ 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 2026-1. 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, 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 2026-1 Period and the budgeted costs related 
to such services are described above.\140\
---------------------------------------------------------------------------

    \139\ See Section 11.3(a)(iii)(B)(B)(2) of the CAT NMS Plan.
    \140\ See Item II.A.1(2)(C)(vi) above.
---------------------------------------------------------------------------

(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.\141\ 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 2026-1. Because there are no CAT employees 
\142\ 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.\143\ 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.\144\
---------------------------------------------------------------------------

    \141\ See Section 11.3(a)(iii)(B)(B)(3) of the CAT NMS Plan.
    \142\ As stated in the filing of the proposed CAT NMS Plan, 
``[i]t is the intent of the Participants that the Company have no 
employees.'' See Securities Exchange Act Release No. 77724 (April 
27, 2016), 81 FR 30614, 30621 (May 17, 2016).
    \143\ CAT LLC uses certain third parties to perform tasks that 
may be performed by administrators for other NMS Plans. See, e.g., 
CTA Plan and CQ Plan.
    \144\ See Item II.A.1(2)(C)(vii) above.
---------------------------------------------------------------------------

(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.\145\ 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 2026-1. 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.'' \146\ As discussed 
above,\147\ 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.\148\

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

(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.\149\ 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 2026-
1. 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.\150\
---------------------------------------------------------------------------

    \149\ See Section 11.3(a)(iii)(B)(B)(5) of the CAT NMS Plan.
    \150\ See Item II.A.1(2)(C)(ix) above.
---------------------------------------------------------------------------

    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.\151\
---------------------------------------------------------------------------

    \151\ See supra note 150.
---------------------------------------------------------------------------

    CAT LLC anticipates continuing to make use of Grant Thornton, an 
independent accounting firm, to complete the audit of CAT LLC's 
financial statements, in accordance with

[[Page 28084]]

the requirements of the CAT NMS Plan. CAT LLC determined that the 
budgeted costs for Grant Thornton 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 performed by Grant Thornton and 
the budgeted costs related to such services are described above.\152\
---------------------------------------------------------------------------

    \152\ See supra note 150.
---------------------------------------------------------------------------

(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.\153\ However, as described above,\154\ CAT LLC determined not to 
include any public relations costs in Budgeted CAT Costs 2026-1. CAT 
LLC determined that it was reasonable not to include any public 
relations costs in the Budgeted CAT Costs 2026-1.
---------------------------------------------------------------------------

    \153\ See Section 11.3(a)(iii)(B)(B)(6) of the CAT NMS Plan.
    \154\ See Item II.A.1(2)(C)(x) above.
---------------------------------------------------------------------------

(xi) Interest Income
    Section 11.1(a) of the CAT NMS Plan requires the CAT budget to 
include ``the sources of all revenues to cover costs.'' Accordingly, 
the Updated 2026 CAT Budget includes a line item for interest income. 
Specifically, the Updated 2026 CAT Budget includes $1,453,382 in 
interest income for the CAT Fee 2026-1 Period.\155\ CAT LLC determined 
that using interest income to reduce the amount to be collected via CAT 
Fees is reasonable and should be included as a part of the Budgeted CAT 
Costs 2026-1.
---------------------------------------------------------------------------

    \155\ See chart entitled ``Budgeted CAT Costs 2026-1'' in Item 
II.A.1(2)(C) above.
---------------------------------------------------------------------------

(xii) 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.\156\ CAT LLC determined that the reserve in the amount of 25% of 
the Updated 2026 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 
2026 CAT Budget.
---------------------------------------------------------------------------

    \156\ See 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 appropriate for the annual operating budget for 
the CAT to ``include a reserve of not more than 25% of the annual 
budget.'' \157\ In making this statement, the Commission noted the 
following:
---------------------------------------------------------------------------

    \157\ See CAT Funding Model Approval Order, 91 FR 13410, 13444.

    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 appropriate 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 has sufficient resources to cover costs should 
there be unanticipated costs or costs that are higher than 
expected.\158\
---------------------------------------------------------------------------

    \158\ See supra note 157.

    The SEC also recognized that a reserve would help address the 
difficulty in predicting certain variable CAT costs, like trading 
volume.\159\ 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.\160\ The 
inclusion of the proposed reserve in the Updated 2026 CAT Budget would 
provide each of these benefits to the CAT. The reserve is discussed 
further above.\161\
---------------------------------------------------------------------------

    \159\ See supra note 157.
    \160\ See supra note 157.
    \161\ See Item II.A.1(2)(C)(xii) above.
---------------------------------------------------------------------------

    As discussed further below,\162\ however, a surplus reserve balance 
in excess of the budgeted 25% reserve has been collected as of the 
beginning of the year of 2026. Accordingly, the Updated 2026 CAT Budget 
indicates that this surplus would be used to offset a portion of CAT 
costs for the CAT Fee 2026-1 Period, thereby reducing the fee rate for 
CAT Fee 2026-1 ($0.000001 per executed equivalent share). If the fee 
rate for CAT Fee 2026-1 were calculated solely based on the reasonably 
budgeted costs for CAT for May-December 2026, excluding the reduction 
in that amount due to the surplus reserve offset, the fee rate would be 
$0.000010 per executed equivalent share.
---------------------------------------------------------------------------

    \162\ See Item II.A.2(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.'' \163\ As discussed above,\164\ this reserve balance 
of $102,391,135 collected via prior CAT Fees would be used to offset a 
portion of CAT costs for CAT Fee Period 2026-1, thereby reducing the 
fee rate to be paid for CAT Fee 2026-1. Specifically, the total costs 
(including the 25% reserve) for CAT Fee 2026-1 of $117,540,783 would be 
reduced by the $102,391,135 in reserve. Therefore, the Total Budgeted 
CAT Costs 2026-1 would be $15,149,648. Such surplus reserve balance 
would be used to reduce the fee rate for CAT Fee 2026-1 ($0.000001 per 
executed equivalent share).
---------------------------------------------------------------------------

    \163\ See Section 11.3(a)(iii)(B)(C) of the CAT NMS Plan.
    \164\ See Item II.A.1(2)(C)(xii) above.
---------------------------------------------------------------------------

(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 March 2025 through February 
2026 was 5,980,937,549,360.49 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.\165\
---------------------------------------------------------------------------

    \165\ See Item II.A.1(2)(D) above.
---------------------------------------------------------------------------

(D) Projected Executed Equivalent Share Volume for the CAT Fee 2026-1 
Period
    CAT LLC has determined that the projected total executed equivalent 
share volume for the eight months of the CAT Fee 2026-1 Period by 
multiplying by 8/12ths the executed equivalent share volume for the 
prior twelve months: 8/12 times 5,980,937,549,360.49 executed 
equivalent shares.\166\ The Operating Committee determined that such an 
approach was reasonable as the CAT's annual executed equivalent share 
volume has increased from prior years (e.g., the executed equivalent 
share volume for 2024 was 4,295,884,600,069.41), and the Operating 
Committee believes that it is reasonable to conclude that the annual 
executed equivalent share volume will remain at the higher level.
---------------------------------------------------------------------------

    \166\ See supra note 165.
---------------------------------------------------------------------------

(E) Actual Fee Rate for CAT Fee 2026-1
(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

[[Page 28085]]

relevant number of decimal places for the fee rate.\167\ Accordingly, 
proposed paragraph (a)(1)(F)(ii) of Rule 6897 would set forth a fee 
rate of $0.000001 per executed equivalent share. This fee rate is 
calculated by multiplying Fee Rate 2026-1 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.\168\
---------------------------------------------------------------------------

    \167\ See CAT Funding Model Approval Order, 91 FR 13410, 13445, 
n.677.
    \168\ See Item II.A.1(4)(A) above.
---------------------------------------------------------------------------

(ii) Reasonable Fee Level
    FINRA believes that charging CAT Fee 2026-1 with a fee rate of 
$0.000001 per executed equivalent share is reasonable because it 
provides for a revenue stream for the Company that is aligned with the 
Budgeted CAT Costs 2026-1. Moreover, FINRA believes that the level of 
the fee rate is reasonable in that it is calculated in accordance with 
the SEC-approved CAT Funding Model, it is less than CAT Fee 2025-2 and 
is comparable to other transaction-based fees, including fees assessed 
pursuant to Section 31.\169\ As a result, the magnitude of CAT Fee 
2026-1 is small, and therefore will mitigate any potential adverse 
economic effects or inefficiencies.\170\
---------------------------------------------------------------------------

    \169\ For example, as the SEC noted in the CAT Funding Model 
Approval Order, recent Section 31 fees ranged from $0.00007 per 
share to $0.00072 per share. See CAT Funding Model Approval Order, 
91 FR 13410, 13469.
    \170\ See supra note 169.
---------------------------------------------------------------------------

(3) CAT Fee 2026-1 Provides for an Equitable Allocation of Fees
    CAT Fee 2026-1 provides for an equitable allocation of fees, as it 
equitably allocates CAT costs between and among the Participants and 
Industry Members, in accordance with the SEC-approved CAT Funding 
Model. 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.\171\ In approving the CAT 
Funding Model, the SEC stated that ``[t]he Participants have 
sufficiently demonstrated that the proposed allocation of fees is 
appropriate and meets the Rule 608(b) approval standard.'' \172\ 
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.
---------------------------------------------------------------------------

    \171\ See Section 11.3(a) of the CAT NMS Plan.
    \172\ See CAT Funding Model Approval Order, 91 FR 13410, 13412.
---------------------------------------------------------------------------

    CAT Fee 2026-1 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 2026-1 complies with the formula set forth in 
Section 11.3(a) of the CAT NMS Plan. In addition, CAT Fee 2026-1 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 2026-1 through a fee 
implemented via the CAT NMS Plan, which would have the same fee rate as 
CAT Fee 2026-1.
    In addition, as discussed above, each of the inputs into the 
calculation of CAT Fee 2026-1--the Budgeted CAT Costs 2026-1, the count 
for the executed equivalent share volume for the prior 12 months, and 
the projected executed equivalent share volume for the CAT Fee 2026-1 
Period--is reasonable. Moreover, these inputs lead to a fee rate for 
CAT Fee 2026-1 that is reasonable as it is consistent with the SEC-
approved CAT Funding Model and 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 2026-1 is Not Unfairly Discriminatory
    CAT Fee 2026-1 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 2026-1 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 2026-1 and 
the resulting fee rate for CAT Fee 2026-1 is reasonable, consistent 
with the SEC-approved CAT Funding Model. Therefore, CAT Fee 2026-1 does 
not impose an unfairly discriminatory fee on Industry Members.
    FINRA 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 proposed paragraph 
(a)(1)(F) of Rule 6897. FINRA also believes that the proposed fees are 
reasonable in that they would provide ease of calculation, ease of 
billing and other administrative functions, and predictability of a fee 
based on a fixed rate per executed equivalent share and are consistent 
with the SEC-approved CAT Funding Model. Such factors are crucial to 
estimating a reliable revenue stream for CAT LLC and for permitting 
Industry Members to reasonably predict their payment obligations for 
budgeting purposes.

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

    FINRA 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.
    Section 15A(b)(9) of the Act \173\ requires that FINRA rules not 
impose any burden on competition that is not necessary or appropriate 
in furtherance of the purpose of the Exchange Act. FINRA notes that CAT 
Fee 2026-1 implements provisions of the CAT NMS Plan that were approved 
by the Commission and is designed to assist FINRA in meeting its 
regulatory obligations pursuant to the Plan.
---------------------------------------------------------------------------

    \173\ 15 U.S.C. 78o-3(b)(9).
---------------------------------------------------------------------------

    In addition, all Participants (including exchanges and FINRA) are 
proposing to introduce CAT Fee 2026-1 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.\174\ 
The SEC also analyzed the potential effect of CAT fees calculated 
pursuant to the CAT Funding Model on

[[Page 28086]]

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 2026-1 is calculated and 
implemented in accordance with the CAT Funding Model as approved by the 
SEC.
---------------------------------------------------------------------------

    \174\ See CAT Funding Model Approval Order, 91 FR 13410, 13457-
81.
---------------------------------------------------------------------------

    As discussed above, each of the inputs into the calculation of CAT 
Fee 2026-1 is reasonable and the resulting fee rate for CAT Fee 2026-1 
calculated in accordance with the CAT Funding Model is reasonable. 
Therefore, CAT Fee 2026-1 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

    Written comments were neither solicited nor 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 \175\ and paragraph (f)(2) of Rule 19b-4 
thereunder.\176\ At any time within 60 days of the filing of the 
proposed rule change, the Commission summarily may temporarily suspend 
such rule change if it appears to the Commission that such action is 
necessary or appropriate in the public interest, for the protection of 
investors, or otherwise in furtherance of the purposes of the Act. If 
the Commission takes such action, the Commission shall institute 
proceedings to determine whether the proposed rule should be approved 
or disapproved.
