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

    \1\ In July 2012, the Commission adopted Rule 613 of Regulation 
NMS, which required the Participants to jointly develop and submit 
to the Commission a national market system plan to create, 
implement, and maintain a consolidated audit trail (the ``CAT''). 
See Securities Exchange Act Release No. 67457 (July 18, 2012), 77 FR 
45722 (Aug. 1, 2012 (``Rule 613 Adopting Release''); 17 CFR 242.613. 
On November 15, 2016, the Commission approved the CAT NMS Plan. See 
Securities Exchange Act Release No. 78318 (Nov. 15, 2016), 81 FR 
84696 (Nov. 23, 2016) (``CAT NMS Plan Approval Order''). The CAT NMS 
Plan is Exhibit A to the CAT NMS Plan Approval Order. See CAT NMS 
Plan Approval Order, at 84943-85034.
    \2\ 15 U.S.C 78k-1(a)(3).

from Robert Walley, CAT NMS Plan Operating Committee Chair, dated 
December 18, 2025.
---------------------------------------------------------------------------

II. Description of the Plan Amendment

    Set forth in this Section II is the description of the proposed 
2025 Cost Savings Amendment, along with information required by Rule 
608(a) under the Exchange Act,\5\ as prepared and submitted by the 
Participants to the Commission.\6\
---------------------------------------------------------------------------

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

    CAT LLC strongly supports meaningful reductions in CAT costs while 
preserving the system's core regulatory functionality. To this end, CAT 
LLC and the Plan Processor have continuously pursued cost savings 
measures within their control and have achieved meaningful cost 
reductions within the significant regulatory restraints of the CAT NMS 
Plan.\7\ In addition, CAT LLC has proposed to the Commission a series 
of cost savings amendments, exemptive relief requests, and no action 
requests to allow the CAT to operate on a more efficient and cost-
effective basis.\8\ While the Participants have achieved meaningful 
savings to date, more comprehensive cost reductions require Commission 
approval to permit their implementation.
---------------------------------------------------------------------------

    \7\ Under CAT NMS Plan requirements, the CAT must process and 
store extremely large data volumes within strict requirements that 
leave little room for flexibility or discretion. However, as a 
result of the optimizations pursued by CAT LLC and the Plan 
Processor, per unit costs have decreased significantly, allowing 
cloud fees to remain generally flat over the last three years 
despite 41% growth in data volumes over the same three-year period--
$136 million and 109 trillion events in 2022, $128 million and 116 
trillion events in 2023, and $135 million and 154 trillion events in 
2024.
    \8\ Prior CAT NMS Plan amendments, exemptive relief requests, 
and no-action requests are available on the CAT website at 
<a href="http://www.catnmsplan.com">www.catnmsplan.com</a>. For example, last year, CAT LLC sought and 
received SEC approval of a cost savings amendment that would permit 
more efficient processing and storage of Options Market Maker Quotes 
in Listed Options. See Exchange Act Release No. 101901 (Dec. 12, 
2024), 89 FR 103033 (Dec. 18, 2024) (``2024 Cost Savings 
Amendment''). This amendment was originally estimated to result in 
roughly $20 million in additional annual savings in the first year, 
but actual savings have proven better than anticipated and are now 
projected to be approximately $30 million in the first year. More 
recently, the Commission instituted proceedings on another Plan 
amendment that would permit CAT LLC to fully eliminate Customer 
names, addresses, and dates of birth information from the CAT, which 
would achieve an estimated $7 to $9 million in annual cost savings. 
See Exchange Act Release No. 103288 (June 17, 2025), 90 FR 26637 
(June 23, 2025) (``CAIS Amendment'').
---------------------------------------------------------------------------

    The CAT operating budget initially approved by the Operating 
Committee for 2025 was approximately $249 million.\9\ In May 2025, the 
Participants revised the budget down by $21 million dollars to 
approximately $228 million to reflect cost savings achieved through the 
implementation of the 2024 Cost Savings Amendment and other 
optimizations.\10\ In November 2025, the Participants further revised 
the budget down by another $40 million to approximately $188 million 
due to further implementation of the 2024 Cost Savings Amendment and 
other optimizations.\11\ This $188 million budget includes 
approximately $122 million in cloud hosting fees, $54 million in Plan 
Processor operating fees and expenses, and other general and 
administrative costs.
---------------------------------------------------------------------------

    \9\ See Consolidated Audit Trail, LLC 2025 Financial and 
Operating Budget (Nov. 20, 2024), <a href="https://www.catnmsplan.com/sites/default/files/2024-11/11.20.24-CAT-LLC-2025-Financial_and_Operating-Budget.pdf">https://www.catnmsplan.com/sites/default/files/2024-11/11.20.24-CAT-LLC-2025-Financial_and_Operating-Budget.pdf</a>.

Operating Budget (May 19, 2024), <a href="https://www.catnmsplan.com/sites/default/files/2025-05/05.19.25-CAT-LLC-2025-Financial_and_Operating-Budget.pdf">https://www.catnmsplan.com/sites/default/files/2025-05/05.19.25-CAT-LLC-2025-Financial_and_Operating-Budget.pdf</a>.
    \11\ See Consolidated Audit Trail, LLC 2025 Financial and 
Operating Budget (Nov. 7, 2025), <a href="https://www.catnmsplan.com/sites/default/files/2025-11/11.07.25-CAT-LLC-2025-Finacial_and_Operating-Budget.pdf">https://www.catnmsplan.com/sites/default/files/2025-11/11.07.25-CAT-LLC-2025-Finacial_and_Operating-Budget.pdf</a>. This most recent budget does not reflect the potential 
cost savings related to the 2025 Cost Savings Exemptive Order. See 
Exchange Act Release No. 104144 (Sept. 30, 2025), 90 FR 47853 (Oct. 
2, 2025) (``2025 Cost Savings Exemptive Order''). Any such cost 
savings would be reflected in 2026 or subsequent years after 
technology and other changes related to the 2025 Cost Savings 
Exemptive Order are implemented.
---------------------------------------------------------------------------

    Based on current estimates, CAT LLC anticipates that this 2025 Cost 
Savings Amendment may reduce CAT costs (currently operating with an 
approximate $188 million annual budget) by approximately $55 to $73 
million per year, without compromising the regulatory purposes of the 
CAT.\12\

[[Page 61507]]

CAT LLC notes that these estimated cost savings are based on current 
costs for 2025 and are inclusive of potential cost savings related to 
the 2025 Cost Savings Exemptive Order recently issued by the 
Commission. As detailed below, several components of this 2025 Cost 
Savings Amendment would codify and/or build upon elements of the 2025 
Cost Savings Exemptive Order; these savings are consolidated and should 
not be combined with savings described in the 2025 Cost Savings 
Exemptive Order to avoid double-counting. CAT LLC respectfully urges 
the Commission to approve this 2025 Cost Savings Amendment 
expeditiously so that these cost savings measures may be implemented as 
soon as possible.
---------------------------------------------------------------------------

    \12\ All cost and savings projections described in this proposed 
amendment are estimates only and reflect the current state and costs 
of CAT operations, including the current number of exchanges. Cost 
savings estimates are based on, among other factors: current CAT NMS 
Plan requirements; reporting by Participants, Industry Members and 
market data providers; observed data rates and volumes; current 
discounts, reservations and cost savings plans and associated cloud 
fees. Actual future savings could be more or less than estimated due 
to changes in any of these variables. Savings projections are 
primarily based on production environments, which represent 
approximately two-thirds of all cloud fees. Factors considered in 
the cost savings estimates are further discussed below. All cost 
savings projections provided in this 2025 Cost Savings Amendment are 
the Plan Processor's best estimates based on the current costs and 
state of the CAT System and are subject to change based on ongoing 
improvements to cloud computing or other changes that may impact 
current CAT costs. Furthermore, certain cost estimates are subject 
to further contract negotiations with CAT LLC's vendors. In 
approving prior CAT LLC cost savings amendments, ``[t]he Commission 
acknowledge[d] the necessity of using simplifying assumptions to 
generate estimates and that such assumptions can affect the 
precision of the estimates,'' and that, even where the Commission 
identified potential issues with such assumptions that ``could 
affect the magnitude of the cost estimates,'' approval was warranted 
in that case because ``the cost savings will be meaningful 
regardless of these issues.'' 2024 Cost Savings Amendment Approval 
Order at 103046. See also Exchange Act Release No. 98290, 88 FR 
62628, 62641 (Sept. 12, 2023) (``The Commission does not believe it 
is possible for the Participants to predict with certainty how the 
magnitude of each driver of CAT costs will change over time.'') CAT 
LLC believes that the cost savings under the 2025 Cost Savings 
Amendment will be meaningful, even if the magnitude of the estimated 
savings cannot be determined with absolute certainty, and that the 
estimates and assumptions described herein provide an adequate basis 
for the Commission to evaluate the costs and benefits of the 
proposed amendment. CAT LLC further notes that the estimated cost 
savings are based on current costs for 2025, which do not reflect or 
incorporate potential cost savings related to the 2025 Cost Savings 
Exemptive Order. CAT LLC also notes that, in some cases as noted 
below, the potential cost savings allowed under the 2025 Cost 
Savings Exemptive Order and the cost savings described in this 2025 
Cost Savings Amendment may differ.
---------------------------------------------------------------------------

    In developing this 2025 Cost Savings Amendment, CAT LLC, with the 
Plan Processor, thoroughly considered a range of alternatives and 
variations to the proposals described in this amendment, balancing the 
potential costs and benefits of each, including regulatory impact. In 
particular, and as discussed below, CAT LLC prepared an initial 
proposal (``Original CAT LLC Proposal'') that was then presented to 
certain Industry Members for feedback. Based on feedback from the 
Advisory Committee and others in the industry, CAT LLC determined to 
amend the Original CAT LLC Proposal and to propose this 2025 Cost 
Savings Amendment instead. As a result, the 2025 Cost Savings Amendment 
is the product of ongoing discussions among the SEC staff, 
Participants, the Plan Processor, the Advisory Committee and Industry 
Members to identify changes to the CAT that would allow the CAT to 
operate more efficiently while preserving its regulatory benefits. It 
is an ongoing priority for the CAT to operate in a cost-effective 
manner, and CAT LLC will continue to explore cost savings opportunities 
that do not compromise the regulatory goals of the CAT.
    Original CAT LLC Proposal to Maximize Cost Savings (Estimated 
Savings of ~$70 to $90 Million). CAT LLC developed a proposal designed 
to maximize cost savings while preserving the CAT's core regulatory 
functionality (``Original CAT LLC Proposal''). The Original CAT LLC 
Proposal is estimated to provide approximately $70 to $90 million in 
annual cost savings, which includes an annual reduction in cloud 
hosting fees of $55 to $75 million, and approximately $15 million in 
total Plan Processor operating fees.\13\
---------------------------------------------------------------------------

    \13\ The Plan Processor's estimates of Plan Processor operating 
fees for the Original CAT LLC Proposal and the modified proposal as 
set forth in this 2025 Cost Savings Amendment are preliminary and 
directional and are subject to change based on the final, SEC-
approved requirements and execution of a new definitive agreement 
between CAT LLC and Plan Processor. These estimates are annualized 
for 2026 based on the estimated Plan Processor operating fees for 
the reduced scope of work reflected in the Original CAT LLC Proposal 
and the Modified Proposal, as applicable. The ``contract year'' for 
the Plan Processor Agreement with FINRA CAT is offset from the 
calendar year, and so the actual total Plan Processor operating fees 
for calendar year 2026 will vary from these annualized estimates. 
The Plan Processor operating fees for future years will also be 
subject to adjustments as agreed between CAT LLC and FINRA CAT 
(e.g., change orders, market data providers and inflation 
adjustments based on a cost of labor index).
---------------------------------------------------------------------------

    As described below, the Original CAT LLC Proposal calls for the 
full elimination of the CAT Customer & Account Information System 
(``CAIS'') and the CAT Customer ID (``CCID''). As noted above, the 
current 2025 CAT budget of $188 million includes an estimated $122 
million in cloud hosting services and $54 million in total Plan 
Processor fees.\14\ Under the Original CAT LLC Proposal, the current 
CAIS-related cloud hosting services fees, estimated at $6.5 to $9 
million, would be eliminated. The current CAIS-related Plan Processor 
fees, estimated at $24.5 million ($20.7 million in operating fees and 
$3.8 million in licensing fees), would also be eliminated, but would be 
offset in part by other estimated increases in Plan Processor fees, 
resulting in total Plan Processor fees of approximately $39 million on 
an annualized basis. Thus, overall, the Plan Processor has proposed a 
$15 million reduction ($54 million reduced to $39 million) in total 
Plan Processor fees under the Original CAT LLC Proposal.
---------------------------------------------------------------------------

    \14\ Note that the $54 million figure for 2025 does not include 
certain other technology expenses that have been budgeted such as 
market data vendor fees ($538,639) and change requests ($1,900,000 
actual costs and an additional $325,000 budget placeholder). For 
additional details about CAIS-related expenses, see Letter from 
Brandon Becker, CAT NMS Plan Operating Committee Chair, to Vanessa 
Countryman, Secretary, Commission (Mar. 7, 2025); Letter from 
Brandon Becker, CAT NMS Plan Operating Committee Chair, to Vanessa 
Countryman, Secretary, Commission (May 28, 2025); Letter from Robert 
Walley, CAT NMS Plan Operating Committee Chair, to Vanessa 
Countryman, Secretary, Commission (Dec. 1, 2025).
---------------------------------------------------------------------------

    The Original CAT LLC Proposal includes the following eight 
components:

    Discussions with Industry regarding Original CAT LLC Proposal. CAT 
LLC discussed two aspects of the Original CAT LLC Proposal--the Full 
Elimination of CAIS/CCID component and the Reduced Linkage Processing 
Timeline component--that would, if approved, have a direct impact on 
Industry Members with members of the Advisory Committee, the Securities 
Industry and Financial Markets Association (``SIFMA'') and the 
Financial Information Forum (``FIF''). While CAT LLC understands that 
not all Industry Members share the same views on these proposals, the 
clear consensus of these discussions was that, while these proposals 
would achieve significant CAT cost savings, they would impose certain 
compliance costs on Industry Members. Based on industry feedback from 
these discussions, CAT LLC determined to modify these two components of 
the Original CAT LLC Proposal as follows for the 2025 Cost Savings 
Amendment.
    <bullet> CAT LLC is proposing the Reference Data Amendment (as 
described below) instead of the Full Elimination of CAIS/CCID component 
of the Original CAT LLC Proposal. With this change, potential cost 
savings in annual cloud hosting costs would be reduced from 
approximately $6.5 to $9 million to approximately $4 to $6 million.
    <bullet> CAT LLC has determined not to include the Reduced Linkage 
Processing Timeline Component of the Original CAT LLC Proposal in the 
2025 Cost Savings Amendment.
    With this change, potential cost savings in annual cloud hosting 
costs would be reduced by approximately $6 to $8 million.
    In addition to the reduction in cost savings for cloud hosting 
services, by changing these two components of the Original CAT LLC 
Proposal, cost savings related to reduced Plan Processor operating fees 
would be reduced by approximately $8 million.
    2025 Cost Savings Amendment (Estimated Savings of ~$55 to $73 
Million). The 2025 Cost Savings Amendment would consist of the 
following seven items described below with their estimated annual 
savings. Note that the first six items of the 2025 Cost Savings 
Amendment are the same as the first six items of the Original CAT LLC 
Proposal.

    Additionally, as described below, CAT LLC proposes to amend the CAT 
NMS Plan to adopt a spending cap provision that is designed to 
safeguard against future requests or interpretations that would expand 
the then-existing functionality or system operations of the CAT without 
a clear assessment of whether the costs outweigh any associated 
benefits.
    The proposed changes to the CAT NMS Plan to implement the 2025 Cost 
Savings Amendment are set forth in Exhibit A \15\ to this filing.\16\
---------------------------------------------------------------------------

    \15\ Exhibit A reflects proposed amendments to the current 
version of the CAT NMS Plan; it does not reflect changes separately 
before the Commission in the pending CAIS Amendment. CAT LLC 
recognizes that the CAIS Amendment and this amendment propose 
changes related to CAIS and the reporting of Customer Identifying 
Information and Customer Account Information. To the extent that 
this amendment were approved prior to the CAIS Amendment, the CAIS 
Amendment would no longer be relevant and CAT LLC would withdraw the 
CAIS Amendment. If the CAIS Amendment were approved prior to this 
amendment, then CAT LLC would update this amendment to reflect the 
changes made in the CAIS Amendment.
    \16\ Because the Commission has acknowledged that Appendix C was 
not intended to be continually updated once the CAT NMS Plan was 
approved, CAT LLC is not proposing to update Appendix C to reflect 
the proposed amendments. See Exchange Act Release No. 89632 (Aug. 
21, 2020), 85 FR 65990 (Oct. 16, 2020).
---------------------------------------------------------------------------

    The timing of when these cost savings will be realized will depend 
on the timing of Commission action on this 2025 Cost Savings Amendment. 
As described in further detail below, the Plan Processor has proposed 
one-time implementation costs and timelines for each component of the 
2025 Cost Savings Amendment, if approved by the Commission, as follows.
    1. Interim CAT-Order-ID Amendment: $225,000 (6 to 8 weeks).
    2. Data Storage Amendment: $165,000 to $265,000: (3 to 4 months).
    3. Late Data Re-Processing Amendment: $250,000 to $500,000 (2 to 4 
months).
    4. OTQT Amendment: $135,000 (8 to 10 weeks).
    5. Rejected Message Amendment: $75,000 to $150,000 (2 to 4 months).
    6. Data Availability Amendment: $200,000 to $400,000 (3 to 6 
months).
    7. Reference Data Amendment: $2.5 to $3.5 million (9 to 12 months).
    Request for Comment on Alternative Proposals. Although CAT LLC is 
proposing more modest cost savings measures based on industry feedback 
than what could be achieved under the Original CAT LLC Proposal, CAT 
LLC agrees with Chairman Atkins' comments that ``CAT must be more 
efficient and cost-effective.'' \17\ CAT LLC also recognizes that the 
Commission has previously exercised its authority to modify proposed 
amendments to the CAT NMS Plan.\18\ CAT LLC believes the Participants 
can satisfy their self-regulatory obligations were the Commission to 
determine to maximize CAT costs savings and modify this amendment to 
incorporate the Original CAT LLC Proposal.

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

    To this end, CAT LLC urges the Commission to request comment and 
quantitative data from Industry Members on the relative cost and 
benefits of the Original CAT LLC Proposal versus this 2025 Cost Savings 
Amendment. In particular, the Commission should request comment 
regarding whether Industry Members support the continued existence of 
the CCID (under the Reference Data Amendment or otherwise) or would 
support its full elimination, and the costs and benefits that could 
result from either approach. Based on discussions with Industry 
Members, CAT LLC understands that while many Industry Members support 
the continued existence of the CCID, some believe that regulators 
should not have the ability to identify a market participant's trading 
activity across multiple CAT Reporters and would support its full 
elimination. In addition, the Commission should request comment 
regarding whether Industry Members support a reduction of the linkage 
processing timeline from four days to two days as discussed in the 
Original CAT LLC Proposal, and the costs and benefits that could result 
from either approach. Based on discussions with Industry Members, CAT 
LLC understands that while many Industry Members support the existing 
timeline, some believe a reduction may be possible if it would not have 
an adverse effect on firm processing and compliance statistics.
    The following table summarizes the differences in estimated cost 
savings between the Original CAT LLC Proposal versus the proposal as 
modified based on industry feedback (reflected in this 2025 Cost 
Savings Amendment), based on the November 2025 budget.

A. Description of the Proposed Amendments to the CAT NMS Plan

1. Interim CAT-Order-ID Amendment: Elimination of Interim CAT-Order-ID/
Maintain Ad Hoc Capability
    CAT LLC proposes to amend the CAT NMS Plan to provide for delivery 
of an interim CAT-Order-ID on an ``as requested by the SEC'' basis, 
rather than on a daily basis (the ``Interim CAT-Order-ID 
Amendment'').\19\ The Interim CAT-Order-ID Amendment would reduce CAT 
annual costs for cloud hosting services by approximately $2 to $3 
million annually, subject to incremental costs incurred for any SEC-
initiated ad hoc requests (as discussed further below).
---------------------------------------------------------------------------

    \19\ CAT LLC originally filed this proposal with the SEC on 
March 27, 2024 as part of the 2024 Cost Savings Amendments. Letter 
from Brandon Becker, CAT NMS Plan Operating Committee Chair, to 
Vanessa Countryman, Secretary, Commission (March 27, 2024), <a href="https://catnmsplan.com/sites/default/files/2024-03/03.27.24-Proposed-CAT-NMS-Plan-Amendment-Cost-Savings-Amendment.pdf">https://catnmsplan.com/sites/default/files/2024-03/03.27.24-Proposed-CAT-NMS-Plan-Amendment-Cost-Savings-Amendment.pdf</a>. After discussions 
with the SEC staff, however, CAT LLC withdrew the proposal. Letter 
from Brandon Becker, CAT NMS Plan Operating Committee Chair, to 
Vanessa Countryman, Secretary, Commission, (Sept. 20, 2024), at 2, 
<a href="https://www.catnmsplan.com/sites/default/files/2024-09/09.20.2024-Cost-Savings-Amendment-OIP-Response.pdf">https://www.catnmsplan.com/sites/default/files/2024-09/09.20.2024-Cost-Savings-Amendment-OIP-Response.pdf</a>. Notwithstanding the 
withdrawal of the prior filing based on discussions with the SEC 
staff, CAT LLC continues to believe that the anticipated savings 
associated with this change substantially outweigh any minimal 
regulatory impact. Accordingly, CAT LLC has determined to re-file 
this proposal with the Commission.
---------------------------------------------------------------------------

    The Interim CAT-Order-ID Amendment is consistent with and would 
codify the exemptive relief related to the interim CAT-Order-ID as set 
forth in the 2025 Cost Savings Exemptive Order.\20\ Correspondingly, 
the estimated cost savings for the Interim CAT-Order-ID Amendment are 
the same as expected with regard to the implementation of the exemptive 
relief in the 2025 Cost Savings Exemptive Order related to the interim 
CAT-Order-ID.\21\ The following compares the estimated annual cost 
savings for cloud hosting services for the exemptive relief related to 
the interim CAT-Order-ID in the 2025 Cost Savings Exemptive Order and 
the Interim-CAT-Order ID Amendment.

                                                  Time.
----------------------------------------------------------------------------------------------------------------

a. Current CAT NMS Plan Requirements
    Section 6.1 of Appendix D of the CAT NMS Plan states that ``Noon 
Eastern Time T+1 (transaction date + one day)'' is the deadline for 
``initial data validation, lifecycle linkages and communication of 
errors to CAT Reporters.'' The CAT NMS Plan further explains that the 
Plan Processor must ``link and create the order lifecycle'' using a 
``daisy chain approach,'' in which ``a series of unique order 
identifiers, assigned to all order events handled by CAT Reporters are 
linked together by the Central Repository and assigned a single CAT-
generated CAT-Order-ID that is associated with each individual order 
event and used to create the complete lifecycle of an order.'' \22\ 
With regard to these provisions, the Commission has stated that
---------------------------------------------------------------------------

    \22\ Section 3 of Appendix D of the CAT NMS Plan at D-8.

    But the CAT NMS Plan does expressly require the creation of 
lifecycle linkages by noon Eastern Time on T+1. And the obligation to 
assign CAT Order IDs--the mechanism by which the Plan Processor creates 
lifecycle linkages--by noon Eastern Time on T+1 necessarily follows 
from that requirement.\23\
---------------------------------------------------------------------------

    \23\ Exchange Act Release No. 95234 (July 8, 2022), 87 FR 42247, 
42251 (July 14, 2022) (``July 2022 Exemptive Order''). See also 
Exchange Act Release No. 97530 (May 18, 2023), 88 FR 33655 (May 24, 
2023); Exchange Act Release No. 90688 (Dec. 16, 2020), 85 FR 83634 
(Dec. 22, 2020).
---------------------------------------------------------------------------

    In its November 2023 Exemptive Order, the Commission granted 
exemptive relief from the requirement to assign an interim CAT-Order-ID 
by T+1 at noon ET, subject to certain conditions. One condition is the 
requirement for the Plan Processor to maintain or improve the existing 
performance of functionality providing lifecycle linkages for all order 
events by T+1 at 9 p.m. ET, except an interim CAT-Order-ID was not 
required for Options Market Maker quotes in Listed Options (``OMM 
Quotes'').\24\ On December 12, 2024, the Commission subsequently 
approved the 2024 Cost Savings Amendment, which removed the requirement 
that OMM Quotes be subject to ``any requirement to link and create an 
order lifecycle,'' such that OMM Quotes need not ``undergo any linkage 
validation, linkage feedback, or lifecycle enrichment processing, but 
will undergo ingestion validation.'' \25\
---------------------------------------------------------------------------

    \24\ Exchange Act Release No. 98848 (Nov. 2, 2023), 88 FR 77130 
(Nov. 8, 2023) (``November 2023 Exemptive Order'').
    \25\ 2024 Cost Savings Amendment at 103034-38.
---------------------------------------------------------------------------

    Accordingly, pursuant to the current CAT NMS Plan and the November 
2023 Exemptive Order, the Plan Processor currently assigns an interim 
CAT-Order-ID by T+1 at 9 p.m. ET, rather than by T+1 at noon ET,\26\ 
except with regard to OMM Quotes, and subsequently provides a final 
CAT-Order-ID at T+5 at

[[Page 61511]]

8 a.m. ET pursuant to the following timeline:
---------------------------------------------------------------------------

    \26\ See November 2023 Exemptive Order.

T+1 @ 8 a.m. ET: Initial submissions due
T+1 @ 12 p.m. ET: Initial data validation, communication of errors to 
CAT Reporters; unlinked data available to regulators
T+1 @ 9 p.m. ET: Interim CAT-Order-ID available \27\
---------------------------------------------------------------------------

    \27\ The Plan Processor is not required to create lifecycle 
linkages for Options Market Maker quotes. Section 3.4 of Appendix D 
of the CAT NMS Plan at D-10.
---------------------------------------------------------------------------

T+3 @ 8 a.m. ET: Resubmission of corrected data
T+4 @ 8 a.m. ET: Final lifecycle assembly begins, reprocessing of late 
submissions and corrections
T+5 @ 8 a.m. ET: Corrected data available to Participant regulatory 
staff and the SEC.\28\
---------------------------------------------------------------------------

    \28\ Section 6.1 of Appendix D of the CAT NMS Plan.
---------------------------------------------------------------------------

b. Conditional Exemptive Relief Regarding the Interim CAT-Order-ID 
Pursuant to 2025 Cost Savings Exemptive Order
    In its 2025 Cost Savings Exemptive Order, the Commission granted 
conditional exemptive relief to allow the Participants to further relax 
requirements related to the provision of the Interim CAT-Order-ID.\29\ 
Specifically, the Commission granted conditional exemptive relief from 
the requirements in Sections 3 and 6.1 of Appendix D of the CAT NMS 
Plan that lifecycle linkages be created by T+1 at noon Eastern Time, 
subject to the following conditions:
---------------------------------------------------------------------------

    \29\ 2025 Cost Savings Exemptive Order at 47854-55.
---------------------------------------------------------------------------

    <bullet> The Plan Processor must provide lifecycle linkages with a 
final CAT-Order-ID for all order events by T+5 at 8 a.m. Eastern Time, 
except that lifecycle linkages will not be required for OMM Quotes 
consistent with the provisions approved by the 2024 Cost Savings 
Amendment.
    <bullet> Upon requests made by authorized regulatory users from the 
Participants or the Commission, the Plan Processor shall create interim 
CAT-Order-IDs for a specified trade date or dates and thereby provide 
linked lifecycles to regulators before T+5 at 8 a.m. Eastern Time.\30\
---------------------------------------------------------------------------

    \30\ Id. at 47855.
---------------------------------------------------------------------------

    The conditional exemptive relief granted in the 2025 Cost Savings 
Exemptive Order supersedes the conditional exemptive relief set forth 
in the November 2023 Exemptive Order with respect to lifecycle linkage 
timeframes.\31\ In providing this exemptive relief, the Commission 
determined that such relief should ``preserve the core regulatory 
benefits of Rule 613 and the CAT NMS Plan, while enabling the 
Participants to realize meaningful cost savings.'' \32\

c. Proposed Revisions to the CAT NMS Plan
    CAT LLC proposes to amend the Plan to state that the Plan does not 
require assignment of interim CAT-Order-IDs on a regular ongoing basis; 
rather, interim CAT-Order-IDs shall be provided only on an ``as 
requested by the SEC'' basis. To implement this change, CAT LLC 
proposes the following changes to the CAT NMS Plan.
    CAT LLC proposes to amend the CAT NMS Plan to eliminate the 
requirement to provide an interim CAT-Order-ID on a regular ongoing 
basis. Specifically, CAT LLC proposes to delete the phrase ``lifecycle 
linkages'' from the following bullet in Section 6.1 of Appendix D of 
the CAT NMS Plan: ``Noon Eastern Time T+1 (transaction date + one day)-
Initial data validation, lifecycle linkages and communication of errors 
to CAT Reporters.'' Similarly, CAT LLC proposes to delete the phrase 
``Life Cycle Linkage'' from the second box in Figure A in Section 6.1 
of Appendix D of the CAT NMS Plan, which currently states: ``12:00 p.m. 
ET T+1 Initial Validation, Life Cycle Linkage, Communication of 
Errors.''
    CAT LLC also proposes to amend the CAT NMS Plan to require CAT LLC 
to provide an interim CAT-Order-ID on an ``as requested by the SEC'' 
basis. Specifically, CAT LLC proposes to add the following provision to 
Section 6.1 of Appendix D of the CAT NMS Plan:

    Upon request of a senior officer of the SEC's Division of 
Trading and Markets, the SEC's Division of Enforcement, or the SEC's 
Division of Examinations to CAT LLC, the Plan Processor shall be 
directed to create an interim CAT-Order-ID and make it available to 
regulators. The timing and cost of ad hoc runs of the interim CAT-
Order-ID would be based on the number of trade dates and the data 
volumes to be processed in the request, but generally would be 
anticipated to be processed by T+2 at 9 p.m. ET if the request is 
received prior to T+2 at 4 a.m. ET, or within 14 hours of receiving 
the request if such request was received after T+2 at 4 a.m. ET.

    As indicated in the draft language, such ad hoc requests for an 
interim CAT-Order-ID may be made by the designated representatives of 
the SEC, not the Participants. The Participants rely on the final CAT-
Order-ID and do not require an interim CAT-Order-ID.
    CAT LLC also proposes to revise Section 6.1 of Appendix D of the 
CAT NMS Plan to clarify that the data made available to Participant 
regulatory staff and the SEC on T+5 must not only be corrected but also 
linked. Specifically, CAT LLC proposes to revise the following bullet 
in Section 6.1 of Appendix D of the CAT NMS Plan: ``8:00 a.m. Eastern 
Time T+5 (transaction date + five days)-Corrected data available to 
Participant regulatory staff and the SEC'' by adding the phrase ``and 
linked.'' With this change, this bullet would read ``8:00 a.m. Eastern 
Time T+5 (transaction date + five days)-Corrected and linked data 
available to Participant regulatory staff and the SEC.'' \33\
---------------------------------------------------------------------------

    \33\ As reflected in Exhibit A to this filing, CAT LLC 
separately proposes changing the reference to ``T+5 (transaction 
data + five days)'' in this sentence to ``T+6 (transaction date + 
six days)'' as part of the Data Availability Amendment.
---------------------------------------------------------------------------

d. The Benefits of the Interim CAT-Order-ID Amendment Significantly 
Outweigh Its Costs
i. The Interim CAT-Order-ID Amendment Would Result in an Estimated $2 
to $3 Million in Annual Cost Savings for Cloud Hosting Services
    Based on current data volumes, delivery of an interim CAT-Order-ID 
on an ``as requested by the SEC'' basis, rather than on a regular 
ongoing basis, is estimated to result in approximately $2 to $3 million 
in annual savings for cloud hosting services.\34\ These cost savings 
estimates are based on certain assumptions and the current scope of the 
CAT, and may vary based on, among other things, the details of the 
requirements in any final amendment approved by the Commission.\35\
---------------------------------------------------------------------------

    \34\ The average typical daily compute costs for interim 
lifecycle processing is estimated to be approximately $8,000/day to 
$12,000/day for a typical day based on current data volumes and 
compute reservations, which totals approximately $2 to $3 million 
per year based on 252 trading days per year.
    \35\ See supra notes 9 and 10.
---------------------------------------------------------------------------

    CAT LLC would add a separate line item to its budget to reflect 
costs related to any SEC requests to generate an interim CAT-Order-ID. 
The estimated cost of an ad hoc interim CAT-Order-ID delivery could 
range from approximately $8,000 to $12,000, but ultimately would depend 
on various unknowns including the then-current availability of compute 
resources and the size of the data volumes to be processed in the 
request.\36\
---------------------------------------------------------------------------

    \36\ This estimate includes compute and storage costs for a 
daily ad hoc interim lifecycle processing and is based on demand 
rates for a typical day with average data volumes. The estimated 
number of authorized ad hoc runs per year that would be requested by 
the SEC cannot be predicted by CAT LLC or the Plan Processor.

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

[[Page 61512]]

    To implement the proposal, the Plan Processor has proposed a one-
time change request fee of approximately $225,000. The Plan Processor 
estimates it would take approximately 6 to 8 weeks to fully implement 
the changes for the Interim CAT-Order-ID Amendment. One-time 
implementation costs will generally consist of Plan Processor labor 
costs associated with coding and software development, as well as any 
related cloud fees associated with the development, testing, and load 
testing of the proposed changes for the proposed amendment. Even 
accounting for this one-time implementation cost, the proposal would 
allow CAT LLC to achieve substantial cost savings in the first 
year.\37\
---------------------------------------------------------------------------

    \37\ CAT LLC plans to rely upon the exemptive relief provided by 
the SEC in its 2025 Cost Savings Exemptive Order regarding the 
Interim CAT-Order-ID. Based on discussions with the Plan Processor, 
CAT LLC understands that approximately 65% of the cost savings 
related to the Interim CAT-Order-ID Amendment would begin to accrue 
after the completion of the first phase of work related to the 
exemptive relief provided with regard to the Interim CAT-Order-ID in 
the 2025 Cost Savings Exemptive Order.
---------------------------------------------------------------------------

ii. The Interim CAT-Order-ID Amendment Would Preserve the Core 
Regulatory Purposes of the CAT
    CAT LLC further believes the Interim CAT-Order-ID Amendment would 
have limited regulatory impact. CAT LLC has determined that eliminating 
the automatic regular assignment of the interim CAT-Order-ID, while 
maintaining the option of assigning an interim CAT-Order-ID on an ad 
hoc basis, would not adversely affect the regulatory objectives of the 
CAT, including market oversight.
    First, as regulators, the Participants rely on the final CAT-Order-
ID and do not require an interim CAT-Order-ID. The interim CAT-Order-ID 
is currently provided on T+1 at 9 p.m. ET, and the final CAT-Order-ID, 
which replaces the interim CAT-Order-ID, is currently provided four 
days later at T+5 at 8 a.m. ET. As the SEC noted in its 2025 Cost 
Savings Exemptive Order, making the final CAT-Order-ID available by T+5 
``should generally continue to be faster than was possible before the 
CAT existed.'' \38\ Moreover, the final CAT-Order-ID reflects reporting 
errors that have been rectified within the Plan's allowed processing 
window. Accordingly, because the CAT is not a real-time system, and the 
final CAT-Order-ID is provided only a short time after the interim CAT-
Order-ID is currently provided, the Participants do not believe that 
elimination of the interim CAT-Order-ID would impact their regulatory 
programs.
---------------------------------------------------------------------------

    \38\ 2025 Cost Savings Exemptive Order at 47855.
---------------------------------------------------------------------------

    Second, as the SEC noted in the 2025 Cost Savings Exemptive Order, 
regulators will be able to access and analyze raw unprocessed data 
prior to T+5 at 8 a.m. Eastern Time, ``which functionality should 
continue to enable regulatory users to effectively and expeditiously 
review data in the case of a major market event, albeit slightly slower 
than is currently possible.'' \39\
---------------------------------------------------------------------------

    \39\ Id.
---------------------------------------------------------------------------

    Third, for those limited instances in which an interim CAT-Order-ID 
is necessary for regulatory purposes, CAT LLC will make the interim 
CAT-Order-ID available upon request of a senior officer of the SEC's 
Division of Trading and Markets, the SEC's Division of Enforcement, or 
the SEC's Division of Examinations to CAT LLC. CAT LLC proposes 
limiting this ability to a senior officer (as opposed to any regulatory 
user of the SEC) to limit the frequency of such requests given the 
significant number of SEC regulatory users and to ensure that the costs 
associated with processing such requests (which could range from 
approximately $8,000 to $12,000, or more, per request) are closely 
aligned with the Commission's priorities. This would preserve the SEC's 
ability to obtain an interim CAT-Order-ID on an as-needed basis (for 
example, in the case of a major market event), while avoiding the 
substantial cost of delivering an interim CAT-Order-ID on a regular 
ongoing basis.
    The Participants believe the availability of such data, combined 
with the ability of the senior officers of the SEC to request an 
interim CAT-Order-ID on an ad hoc basis and the delivery of the final 
CAT-Order-ID, is sufficient for regulatory purposes. Because the CAT is 
a historical regulatory audit trail rather than a real-time system, the 
de minimis benefit that may result from producing an interim CAT-Order-
ID slightly earlier than a final CAT-Order-ID would not justify the 
significant cost.
iii. The Interim CAT-Order-ID Amendment Would Not Adversely Impact 
Industry Members
    CAT LLC also believes the Interim CAT-Order-ID Amendment would 
reduce costs with limited regulatory impact without adversely impacting 
Industry Members. The interim CAT-Order-ID is an internal function 
within CAT, and, therefore, does not directly affect the requirements 
applicable to CAT Reporters. Accordingly, CAT LLC does not anticipate 
that the Interim CAT-Order-ID Amendment would have an adverse impact on 
Industry Members or their costs.
iv. The Interim CAT-Order-ID Amendment Would Enhance Market Efficiency
    CAT LLC also believes the Interim CAT-Order-ID Amendment would 
enhance the efficiency of the securities markets. As discussed above, 
the Interim-CAT-Order-ID Amendment would provide significant annual 
cost savings for CAT LLC. Such cost savings would not only benefit CAT 
LLC, but would also provide cost savings for any Participants and 
Industry Members that are required to fund the CAT in accordance with 
the CAT NMS Plan. Ultimately, such cost savings would benefit investors 
and the U.S. markets as a whole, thereby facilitating the goals of the 
Exchange Act.
2. Data Storage Amendment: Reduction of Retention Period for Certain 
Categories of CAT Data
    CAT LLC proposes to amend the CAT NMS Plan to permit the Plan 
Processor to delete (i) all CAT Data older than three years (other than 
CAT Data with a shorter retention period as described below); (ii) OMM 
Quotes older than six months; (iii) Interim Operational Data older than 
15 days; and (iv) quote and NBBO data included in the SIP Data \40\ 
from the OPRA Plan or any successor SIP \41\ for Listed Options \42\ 
(``Options SIP Data'') older than six months (the ``Data Storage 
Amendment''). The Data Storage Amendment would reduce annual CAT costs 
for cloud hosting services by approximately $23.5 to $32 million 
annually.\43\ To the extent the Commission deems it necessary to grant 
exemptive relief from the recordkeeping and data retention requirements 
of SEC Rule 17a-1 or any other provision under the Exchange Act or the 
CAT NMS Plan in order to effectuate this proposal, for the same reasons 
as discussed herein, CAT LLC requests that the Commission utilize its 
authority under Section 36(a)(1) of the Exchange Act \44\ and Rule

[[Page 61513]]

608(e) of Regulation NMS \45\ to grant such exemptive relief.
---------------------------------------------------------------------------

    \40\ See Section 6.5 of the CAT NMS Plan for the definition of 
``SIP Data.''
    \41\ See Section 1.1 of the CAT NMS Plan for the definition of 
``SIP.''
    \42\ See Section 1.1 of the CAT NMS Plan for the definition of 
``Listed Options.''
    \43\ See supra, note 9.
    \44\ See 15 U.S.C. 78mm(a)(1), which provides, in relevant part, 
that the ``Commission, by rule, regulation, or order, may 
conditionally or unconditionally exempt any person, security, or 
transaction, or any class or classes of persons, securities, or 
transactions, from any provision or provisions of this title or of 
any rule or regulation thereunder, to the extent that such exemption 
is necessary or appropriate in the public interest, and is 
consistent with the protection of investors.''
    \45\ See 17 CFR 242.608(e), which provides that ``[t]he 
Commission may exempt from the provisions of this section, either 
unconditionally or on specified terms and conditions, any self-
regulatory organization, member thereof, or specified security, if 
the Commission determines that such exemption is consistent with the 
public interest, the protection of investors, the maintenance of 
fair and orderly markets and the removal of impediments to, and 
perfection of the mechanisms of, a national market system.''
---------------------------------------------------------------------------

    As discussed further below, the Data Storage Amendment expands upon 
the substance of the exemptive relief related to data storage and 
retention granted by the Commission in the 2025 Cost Savings Exemptive 
Order and further increases the anticipated cost savings related to 
data storage and retention by approximately $6.5 to $9 million. 
Specifically, the Data Storage Amendment expands upon the exemptive 
relief related to data storage and retention as set forth in the 2025 
Cost Savings Exemptive Order by:
    <bullet> Deleting all CAT Data older than three years, rather than 
older than five years;
    <bullet> Deleting OMM Quotes older than six months, rather than 
older than one year; and
    <bullet> Deleting Options SIP Data older than six months, rather 
than older than five years.
    Both the Data Storage Amendment and the exemptive relief provided 
in the 2025 Cost Savings Exemptive Order would allow for the deletion 
of Interim Operational Data older than 15 days. The following compares 
the estimated annual cost savings related to data storage and retention 
relief granted in the 2025 Cost Savings Exemptive Order \46\ and the 
Data Storage Amendment.
---------------------------------------------------------------------------

    \46\ 2025 Cost Savings Exemptive Order at 47857-58. In the 2025 
Cost Savings Exemptive Order, the SEC states that it ``understands 
from its communications with the Participants that such measures 
could save approximately $11-15 million annually.'' Id. at 47858. 
The estimated cost savings set forth in this chart reflect updated 
cost estimates.
    \47\ The cost savings estimate provided in the 2025 Cost Savings 
Exemptive Order for requirements related to data storage and 
retention was $11 to $15 million per year. That estimate was based 
on costs actually incurred through April 2025. The $17 to $23 
million estimate provided in this filing has been updated to reflect 
costs actually incurred through September 2025.

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

a. Current CAT NMS Plan Requirements
    Section 6.1(d)(i) of the CAT NMS Plan requires the Plan Processor 
to comply with the recordkeeping requirements of SEC Rule 613(e)(8). In 
turn, SEC Rule 613(e)(8) requires that the Central Repository retain 
information collected pursuant to SEC Rule 613(c)(7) and (e)(7) in a 
convenient and usable standard electronic data format that is directly 
available and searchable electronically without any manual intervention 
for a period of not less than five years.
    Section 6.5(d) of the CAT NMS Plan provides: ``Consistent with 
Appendix D, Data Retention Requirements, the Central Repository shall 
retain the information collected pursuant to paragraphs (c)(7) and 
(e)(7) of SEC Rule 613 in a convenient and usable standard electronic 
data format that is directly available and searchable electronically 
without any manual intervention by the Plan Processor for a period of 
not less than six (6) years, subject to the exceptions in Section 6.3 
of Appendix D.''
    Section 1.4 of Appendix D of the CAT NMS Plan provides, in relevant 
part, that ``[t]he Plan Processor must develop a formal record 
retention policy and program for the CAT, to be approved by the 
Operating Committee, which will, at a minimum . . . [m]ake data 
directly available and searchable electronically without manual 
intervention for at least six years, subject to the exceptions in 
Section 6.3 of Appendix D.''
    Section 3.4 of Appendix D (Requirements for Options Market Maker 
Quotes in Listed Options) governs the processing and storage of OMM 
Quotes.
    Section 6.3 of Appendix D (Exceptions to Data Availability 
Requirements) provides that ``Raw Unprocessed Data'' older than 15 
days, ``Interim Operational Data'' older than 15 days, and all 
submission and feedback files older than 15 days may be retained in an 
archive storage tier, and that such archived data ``is not directly 
available and searchable electronically without manual intervention and 
will not be subject to any query tool performance requirements until it 
is restored to an accessible storage tier.'' Pursuant to Section 6.3 of 
Appendix D, ``[t]he Plan Processor will restore archived data to an 
accessible storage tier upon request to the CAT Help Desk by an 
authorized regulatory user from the Participants or a senior officer 
from the SEC.''
b. Conditional Exemptive Relief Regarding Data Storage and Retention 
Pursuant to 2025 Cost Savings Exemptive Order
    In its 2025 Cost Savings Exemptive Order, the Commission granted 
conditional exemptive relief from SEC Rule 17a-1, SEC Rule 613(e)(8), 
Sections 6.1(d)(i) and 6.5(b) of the CAT NMS Plan, and Sections 1.4 and 
6.3 of Appendix D of the CAT NMS Plan, to the extent necessary to allow 
the Participants to:
    <bullet> Delete all CAT Data older than five years.
    <bullet> Move CAT Data older than three years to a more cost-
effective storage tier (i.e., a tier requiring some ``manual 
intervention'' to retrieve data), subject to the condition that the 
Plan Processor will restore archived CAT Data which is older than three 
years old to an accessible storage tier upon request to the CAT Help 
Desk by an authorized regulatory user from the Participants or from the 
SEC.
    <bullet> Delete OMM Quotes data after one year from the CAT System.
    <bullet> Delete Interim Operational Data older than 15 days.\48\
---------------------------------------------------------------------------

    \48\ 2025 Cost Savings Exemptive Order at 47858.
---------------------------------------------------------------------------

    In granting this exemptive relief, the Commission stated it ``does 
not believe the reduced data storage and shorter data retention periods 
permitted by the conditional exemptive relief granted herein would 
unduly impact regulators' ability to oversee the markets.'' \49\ The 
SEC stated in the 2025 Cost Savings Exemptive Order that it 
``understands from its communications with the Participants that such 
measures [with regard to the exemptive relief regarding data storage 
and retention) could save

[[Page 61514]]

approximately $11-$15 million annually.'' \50\

c. Proposed Revisions to the CAT NMS Plan
    With the Data Storage Amendment, CAT LLC proposes to amend the CAT 
NMS Plan to permit the Plan Processor to delete (i) all CAT Data older 
than three years; (ii) OMM Quotes older than six months; (iii) Interim 
Operational Data older than 15 days; and (iv) Options SIP Data older 
than six months. The Data Storage Amendment expands upon the exemptive 
relief related to data storage and retention as set forth in the 2025 
Cost Savings Exemptive Order by:
    <bullet> Deleting all CAT Data older than three years, rather than 
older than five years;
    <bullet> Deleting OMM Quotes older than six months, rather than 
older than one year; and
    <bullet> Deleting Options SIP Data older than six months, rather 
than older than five years.
    Both the Data Storage Amendment and the exemptive relief provided 
in the 2025 Cost Savings Exemptive Order would allow for the deletion 
of Interim Operational Data older than 15 days. The Data Storage 
Amendment would reduce CAT costs for cloud hosting services by 
approximately $23.5-$32 million annually. The following chart indicates 
the estimated cost savings for cloud hosting services with regard to 
each of the four components of the Data Storage Amendment.

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

    To implement the Data Storage Amendment, CAT LLC proposes to make 
the following changes to the CAT NMS Plan.
i. Section 6.1(d)(i) of the CAT NMS Plan
    Section 6.1(d)(i) of the CAT NMS Plan states, in relevant part, 
that ``[t]he Plan Processor shall . . . comply with . . . the 
recordkeeping requirements of SEC Rule 613(e)(8).'' CAT LLC proposes to 
replace the requirement to comply with ``the recordkeeping requirements 
of SEC Rule 613(e)(8)'' with a requirement to comply with ``the 
recordkeeping requirements of Section 6.5 and Appendix D.'' \51\ This 
change would simplify Section 6.1(d)(i) by referring to the data 
retention provisions in the CAT NMS Plan itself, and would eliminate 
any confusion or perceived inconsistency regarding legacy language in 
Rule 613 that data be made ``directly available and searchable 
electronically without any manual intervention for a period of not less 
than five years.''
---------------------------------------------------------------------------

    \50\ Id. at 47858, n.61.
    \51\ SEC Rule 613(e)(8) applies to the ``national market system 
plan submitted pursuant to this section'' and was satisfied by the 
original filing of the CAT NMS Plan.
---------------------------------------------------------------------------

ii. Section 6.5(b)(i) of the CAT NMS Plan
    CAT LLC proposes to amend Section 6.5(b)(i) of the CAT NMS Plan to 
permit the Plan Processor to delete CAT Data older than three years. 
Section 6.5(b)(i) of the CAT NMS Plan currently states:

    Consistent with Appendix D, Data Retention Requirements, the 
Central Repository shall retain the information collected pursuant 
to paragraphs (c)(7) and (e)(7) of SEC Rule 613 in a convenient and 
usable standard electronic data format that is directly available 
and searchable electronically without any manual intervention by the 
Plan Processor for a period of not less than six (6) years, subject 
to the exceptions in Section 6.3 of Appendix D. Such data when 
available to the Participant regulatory staff and the SEC shall be 
linked.

    First, CAT LLC proposes to amend this provision to state that CAT 
Data will be retained for a period of not less than three years, and in 
a convenient and usable standard electronic data format that is 
directly available and searchable electronically without any manual 
intervention by the Plan Processor.
    Second, CAT LLC proposes to simplify this provision by replacing 
the references to ``the information collected pursuant to paragraphs 
(c)(7) and (e)(7) of SEC Rule 613'' with ``CAT Data.'' CAT Data is 
defined in Section 1.1 of the CAT NMS Plan to mean ``data derived from 
Participant Data, Industry Member Data, SIP Data, and such other data 
as the Operating Committee may designate as `CAT Data' from time to 
time.'' Participant Data, as defined in Section 6.3(d) of the CAT NMS 
Plan, and Industry Member Data, as defined in Section 6.4(d)(ii) of the 
CAT NMS Plan, collectively, correspond to the information set forth in 
paragraph (c)(7) of SEC Rule 613, subject to certain changes approved 
by the Commission. A comparison of the Plan provisions and the 
corresponding provisions in SEC Rule 613 is set forth in Chart 1 in 
Exhibit D. Similarly, SIP Data, as defined in Section 6.5(a)(ii) of the 
CAT NMS Plan, corresponds to the information set forth in paragraph 
(e)(7) of SEC Rule 613, subject to certain changes approved by the 
Commission. A comparison of the Plan provisions and the corresponding 
provisions in SEC Rule 613 is set forth in Chart 2 in Exhibit D. In 
light of the differences between paragraphs (c)(7) and (e)(7) of SEC 
Rule 613 and the corresponding provisions of the CAT NMS Plan, and to 
eliminate any confusion or perceived inconsistency regarding legacy 
language in SEC Rule 613, CAT LLC believes it is appropriate to refer 
to ``CAT Data'' as defined in the Plan rather than to provisions of SEC 
Rule 613.
    Third, CAT LLC proposes to add a reference to Section 3.4 of 
Appendix D of the CAT NMS Plan, which governs the storage of OMM 
Quotes, and a reference to proposed Section 6.4, which describes the 
reduced retention period for Interim Operational Data and Options SIP 
Data (as discussed below).
    With these proposed changes, Section 6.5(b)(i) of the CAT NMS Plan 
would read as follows:

    Consistent with Appendix D, Data Retention Requirements, the 
Central Repository shall retain CAT Data for a period of not less 
than three (3) years, and in a convenient and usable standard 
electronic data format that is directly available and searchable 
electronically without any manual intervention by the Plan 
Processor, subject to the exceptions in Section 3.4, Section 6.3 and 
Section 6.4 of Appendix D. Such data when available to the 
Participant regulatory staff and the SEC shall be linked.
iii. Section 1.4 of Appendix D of the CAT NMS Plan
    Correspondingly, CAT LLC proposes to amend Section 1.4 of Appendix 
D of the CAT NMS Plan to replace the

[[Page 61515]]

existing provision that requires the Plan Processor to develop a formal 
record retention policy and program for the CAT, which will at a 
minimum ``[m]ake data directly available and searchable electronically 
without manual intervention for at least six years, subject to the 
exceptions in Section 6.3 of Appendix D'' with the following provision: 
``Retain CAT Data for a period of not less than three (3) years and 
make it directly available and searchable electronically without manual 
intervention, subject to the exceptions in Section 3.4, Section 6.3 and 
Section 6.4 of Appendix D.''
iv. Section 3.4 of Appendix D of the CAT NMS Plan
    CAT LLC proposes to amend Section 3.4 of Appendix D of the CAT NMS 
Plan to add the following sentence: ``Notwithstanding any other 
provision of the CAT NMS Plan, this Appendix D, or Exchange Act Rule 
17a-1, Options Market Maker quotes in Listed Options older than six 
months may be deleted by the Plan Processor.''
    The Plan Participant Technical Specifications currently define 
three types of events used to report Options Market Maker Quotes: 
Option Quote (OQ), Option Quote Cancel (OQC) and Option Complex Quote 
(OCQ) events.\52\ Under the proposal, Option Quote (OQ), Option Quote 
Cancel (OQC), and Option Complex Quote (OCQ) events would be deleted 
from the CAT after six months. Trades resulting from an Options Market 
Maker Quote would continue to be reportable as Option Trade (OT) 
events; however, the OT event will not be associated with any OMM 
Quote.

v. Section 6.3 of Appendix D of the CAT NMS Plan
    CAT LLC proposes to amend Section 6.3 of Appendix D of the CAT NMS 
Plan to remove the references to archiving of Interim Operational Data 
older than 15 days. Instead, CAT LLC proposes to delete Interim 
Operational Data older than 15 days. As a result, CAT LLC proposes to 
delete the following from Section 6.3 of Appendix D of the CAT NMS 
Plan:
    <bullet> Interim Operational Data older than 15 days. ``Interim 
Operational Data'' means all processed, validated and unlinked data 
made available to regulators by T+1 at 12:00 p.m. ET and all iterations 
of processed data made available to regulators between T+1 and T+5, but 
excludes the final version of corrected data that is made available at 
T+5 at 8:00 a.m. ET. For the avoidance of doubt, ``Interim Operational 
Data'' does not include processed data relating to Options Market Maker 
quotes in Listed Options made available to regulators by T+1 at 12:00 
p.m. ET.
    CAT LLC proposes to address the retention period of Interim 
Operational Data in new Section 6.4 of Appendix D of the CAT NMS Plan, 
as discussed below.
vi. Section 6.4 of Appendix D of the CAT NMS Plan
    CAT LLC proposes to add a new Section 6.4 to Appendix D of the CAT 
NMS Plan to describe the reduced retention periods for Interim 
Operational Data and Options SIP Data. Specifically, proposed Section 
6.4 of Appendix D of the CAT NMS Plan would state the following:
    Notwithstanding any other provision of the CAT NMS Plan, this 
Appendix D, or Exchange Act Rule 17a-1, the following may be deleted 
from the CAT by the Plan Processor:
    <bullet> Interim Operational Data older than 15 days. ``Interim 
Operational Data'' means all processed, validated and unlinked data 
made available to regulators by T+2 at 8:00 a.m. ET and all iterations 
of processed data made available to regulators between T+2 and T+6, but 
excludes the final version of corrected data that is made available by 
T+6 at 8:00 a.m. ET. For the avoidance of doubt, ``Interim Operational 
Data'' does not include processed data relating to Options Market Maker 
quotes in Listed Options made available to regulators by T+2 at 8:00 
a.m. ET.
    <bullet> Options SIP Data older than six months. ``Options SIP 
Data'' means quote and NBBO data included in the SIP Data from the OPRA 
Plan or any successor SIP for Listed Options.
d. The Benefits of the Data Storage Amendment Significantly Outweigh 
Its Costs
    The benefits of the Data Storage Amendment significantly outweigh 
its costs. This proposal would allow CAT LLC to achieve an estimated 
$23.5-$32 million in annual cost savings for cloud hosting services, 
materially advancing CAT LLC's ongoing efforts to reduce CAT operating 
costs. Moreover, the Data Storage Amendment would not adversely affect 
the core regulatory purposes of the CAT.
i. The Data Storage Amendment Would Result in an Estimated $23.5-$32 
Million in Annual Cost Savings for Cloud Hosting Services
    CAT LLC, after consultation with the Plan Processor, has determined 
the Data Storage Amendment would allow CAT LLC to achieve approximately 
$23.5-$32 million in annual cost savings for cloud hosting 
services.\53\ These cost savings estimates are based on certain 
assumptions and the current scope of the CAT, and may vary based on, 
among other things, the details of the requirements in any final 
amendment approved by the Commission.\54\
---------------------------------------------------------------------------

    \53\ When the Participants originally evaluated the retention 
period for CAT Data when proposing the CAT NMS Plan, it was 
recognized that longer retention periods would increase costs for 
the CAT. See CAT NMS Plan Approval Order at 84778 (noting that 
lengthier retention periods would impact ``the maintenance costs 
associated with the CAT'').
    \54\ See supra notes 9 and 10.
---------------------------------------------------------------------------

    When the CAT NMS Plan was adopted in 2016, it was ``expected that 
the Central Repository will grow to more than 29 petabytes of raw, 
uncompressed data.'' \55\ The Plan Processor currently projects, 
however, that cumulative storage will be approximately 820 to 830 
petabytes for 2025--more than 28 times this original estimate. CAT LLC 
and the Plan Processor have continually implemented optimizations that 
have significantly decreased per-unit storage costs despite increasing 
data volumes, but storage costs remain a significant component of 
overall CAT costs. Since the implementation of the 2024 Cost Savings 
Amendment in April 2025, storage costs during the period Q2 2025 
through Q3 2025 have ranged from 32% to 41% of monthly cloud hosting 
services fees.
---------------------------------------------------------------------------

    \55\ See CAT NMS Plan Approval Order at 85203; Section 1.3 of 
Appendix D of the CAT NMS Plan, at Appendix D-5. Section 6.3 of 
Appendix D provides that raw unprocessed data, interim operational 
data, and submission and feedback files older than 15 days may be 
retained in an archive storage tier.
---------------------------------------------------------------------------

    One major driver of storage costs to date is the requirement that 
CAT Data must be ``directly available and searchable electronically 
without any manual intervention by the Plan Processor for a period of 
not less than six (6) years,'' subject to narrow exceptions approved as 
part of the 2024 Cost Savings Amendment.\56\ The retention of six years 
of CAT Data (or

[[Page 61516]]

even five years of CAT Data under the 2025 Cost Savings Exemptive 
Order, which has not yet been implemented) would continue to lead to 
significant costs that outstrip regulatory need.\57\
---------------------------------------------------------------------------

    \56\ CAT NMS Plan at Section 6.5(b)(i). Section 6.3 of Appendix 
D (Exceptions to Data Availability Requirements) provides that ``Raw 
Unprocessed Data'' older than 15 days, ``Interim Operational Data'' 
older than 15 days, and all submission and feedback files older than 
15 days may be retained in an archive storage tier.
    \57\ CAT proposes to delete data older than three years rather 
than moving such data to deep archive due to the greater cost 
savings. For example, deleting data from 2019 and 2020, rather than 
moving it to deep archive, would result in additional savings of 
$1.2 million-$1.5 million. This number would fluctuate year-over-
year commensurate with the amount of data eligible for deletion in 
any given year. For example, the effective savings for years beyond 
2021 would increase due to greater amounts of data in those later 
years as a result of the implementation of later CAT reporting 
phases and organic market volume growth.
---------------------------------------------------------------------------

    Another major driver of storage costs is OMM Quotes. OMM Quotes 
(the vast majority of which result in a cancellation) are the single 
largest data source for the CAT, comprising approximately 98% of all 
Options Exchange events and approximately 44% of all transaction 
volume.\58\ The Participants have been working to limit the costs 
related to OMM Quotes since the inception of the CAT.\59\ Although 
these prior efforts have realized significant cost savings, the costs 
associated with storing six years of OMM Quotes under the CAT NMS Plan 
(or even one year under the 2025 Cost Savings Exemptive Order), remains 
high in light of the limited regulatory uses and benefits of such data, 
as described in more detail in Section A.2.d.ii below. Accordingly, CAT 
proposes to delete OMM Quotes older than six months.\60\
---------------------------------------------------------------------------

    \58\ Under Section 1.1 of the CAT NMS Plan, a ``Reportable 
Event'' ``includes, but is not limited to, the original receipt or 
origination, modification, cancellation, routing, execution (in 
whole or in part) and allocation of an order, and receipt of a 
routed order.'' Section 1.1 of the CAT NMS Plan states that an 
``order'' ``has, with respect to Eligible Securities, the meaning 
set forth in SEC Rule 613(j)(8).'' SEC Rule 613(j)(8), in turn, 
states that ``[t]he term order shall include: (i) Any order received 
by a member of a national securities exchange or national securities 
association from any person; (ii) Any order originated by a member 
of a national securities exchange or national securities 
association; or (iii) Any bid or offer.'' Accordingly, the 
definition of an ``order'' includes OMM Quotes, and Reportable 
Events include events related to OMM Quotes.
    \59\ In March 2016, the Commission granted exemptive relief 
permitting OMM Quotes to be reported to the Central Repository by 
the relevant Options Exchange in lieu of requiring that such 
reporting be done by both the Options Exchange and the Options 
Market Maker, as required by Rule 613. Exchange Act Release No. 
77265 (Mar. 1, 2016), 81 FR 11856 (Mar. 7, 2016). In November 2023, 
the Commission granted exemptive relief allowing the Plan Processor 
to create lifecycle linkages for OMM Quotes only once by T+2 at 8 
a.m. ET (as opposed to requiring both an interim lifecycle by T+1 at 
9 p.m. ET and a final lifecycle by T+5 at 8 a.m. ET). See November 
2023 Exemptive Order. In December 2024, the Commission approved the 
2024 Cost Savings Amendment, which provides that OMM Quotes would no 
longer undergo any linkage validation, linkage feedback, or 
lifecycle enrichment processing. See 2024 Cost Savings Amendment 
Approval Order.
    \60\ The 2025 Cost Savings Exemptive Order provides relief for 
OMM Quotes older than a year, but CAT LLC does not believe that this 
is sufficient for cost savings purposes.
---------------------------------------------------------------------------

    Relatedly, the CAT is required to maintain copies of Options SIP 
Data for six years under the CAT NMS Plan (or five years under the 2025 
Cost Savings Exemptive Order). However, such data is voluminous and 
imposes significant costs on the CAT. Options SIP Data currently 
represents 25% of storage costs. Accordingly, like with OMM Quotes, CAT 
proposes to delete Options SIP Data older than six months.
    Furthermore, the CAT is required to maintain all copies of Interim 
Operational Data.\61\ After five years of CAT operation, the 
Participants have not used Interim Operational Data for regulatory 
purposes. Therefore, the cost of retaining this data, even in a lower-
priced archival storage tier, is not justified given its limited usage.
---------------------------------------------------------------------------

    \61\ Section 6.3 of Appendix D of the CAT NMS Plan (Exceptions 
to Data Availability Requirements) describes ``Interim Operational 
Data'' to mean ``all processed, validated and unlinked data made 
available to regulators by T+1 at 12:00 p.m. ET and all iterations 
of processed data made available to regulators between T+1 and T+5, 
but excludes the final version of corrected data that is made 
available at T+5 at 8:00 a.m. ET.''
---------------------------------------------------------------------------

    To implement the Data Storage Amendment, the Plan Processor has 
proposed a one-time change request setting forth an implementation fee 
of approximately $165,000-$265,000. The Plan Processor estimates that 
it would take approximately three to four months to fully implement the 
changes for the Data Storage Amendment. One-time implementation costs 
will generally consist of Plan Processor labor costs associated with 
coding and software development, as well as any related cloud fees 
associated with the development, testing, and load testing of the 
proposed changes for the proposed amendment. Even accounting for this 
one-time implementation cost, the proposal would allow CAT LLC to 
achieve substantial cost savings in the first year.
ii. The Data Storage Amendment Would Preserve the Core Regulatory 
Purposes of the CAT
    CAT LLC believes the cost savings associated with the Data Storage 
Amendment are readily justified given the minimal impact on the 
regulatory purposes of the CAT.
    First, with regard to the proposed three-year retention period for 
CAT Data, based on their regulatory experiences to date, the 
Participants do not anticipate generally needing CAT Data older than 
three years to support their regulatory programs. In addition, as the 
SEC noted with regard to its own use of the CAT, the first three years 
of CAT Data ``will be more frequently accessed and needed by regulatory 
users based on its experience in using the CAT.'' \62\ In addition, 
although the Plan Processor does not have insight into how bulk data 
extracted from the repository (via BDSQL or Direct Read) is used by 
regulators, OTQT usage metrics (via DIVER) from January to November 
2025 demonstrate that only 2% of DIVER requests (750 out of 38,028 
requests) were for trade dates older than three years.
---------------------------------------------------------------------------

    \62\ 2025 Cost Savings Exemptive Order at 47858.
---------------------------------------------------------------------------

    Second, the vast majority of OMM Quote lifecycles do not involve 
any execution or allocation and Participant regulatory users very 
rarely access such data. The SEC recognized that the costs of retaining 
older OMM Quotes exceed their regulatory benefit, stating in the 2025 
Cost Savings Exemptive Order that ``based on Commission experience in 
using the CAT and CAT Data, the Commission expects that regulators are 
less likely to access OMM Quotes data after a period of one year and 
thus the costs of maintaining older OMM Quotes data in the CAT are not 
sufficiently justified by its regulatory benefits.'' \63\ The 
Participants believe the Commission's reasoning is also applicable to 
OMM Quotes older than six months, not just OMM Quotes older than one 
year.
---------------------------------------------------------------------------

    \63\ Id.
---------------------------------------------------------------------------

    Third, the Participants also do not believe that the cost of 
retaining Options SIP Data for more than six months is justified by 
regulatory need. Based on their regulatory experiences to date, the 
Participants generally do not anticipate needing Options SIP Data older 
than six months to support their regulatory programs.
    Fourth, as noted above, Interim Operational Data generally does not 
provide any regulatory value after the final corrected version of CAT 
Data is delivered by T+5 at 8 a.m. ET. Regulators generally access the 
latest, corrected version of CAT Data, and after five years of 
operation, the Participants have not made use of the Interim 
Operational Data for regulatory purposes. Under the 2024 Cost Savings 
Amendment, Interim Operational Data may be retained in a low-cost 
archive storage tier, but the costs associated with storing this data 
even in an archive storage tier continue to outweigh any regulatory 
benefit. The SEC agreed with this conclusion when it stated that 
``deleting Interim Operational Data older

[[Page 61517]]

than 15 days will likely have little effect, as the Commission 
understands from communications with the Participants that it has not 
been used after nearly five years of CAT operation.'' \64\
---------------------------------------------------------------------------

    \64\ Id.
---------------------------------------------------------------------------

    Finally, to the extent any Participant or the SEC determined a need 
for CAT Data that would be deleted pursuant to these proposed 
revisions, the data could be copied and stored separately within its 
own environment for its own use. In addition, the underlying 
Participant and Industry Member data would continue to be available to 
the SEC for the full retention periods mandated by SEC Rule 17a-1 and 
SEC Rule 17a-4.\65\ Accordingly, in the unlikely event that a regulator 
required such data, the regulator could request such data directly from 
Participants or Industry Members, as appropriate. Based on their 
regulatory experiences to date, however, the Participants expect that 
such instances would be rare, and, as result, such costs would be de 
minimis.
---------------------------------------------------------------------------

    \65\ SEC Rule 17a-1(b) requires national securities exchanges 
and national securities association to retain documents described 
therein for at least five years. SEC Rule 17a-4(a) requires broker-
dealers to retain the information described therein for a six-year 
time frame. In addition, the CAT Compliance Rules of each of the 
Participants set forth the recordkeeping obligations related to the 
CAT for Industry Members. See, e.g., FINRA Rule 6890.
---------------------------------------------------------------------------

iii. The Data Storage Amendment Would Not Adversely Impact Industry 
Members
    CAT LLC also believes the Data Storage Amendment would reduce costs 
with limited regulatory impact without having an adverse impact on 
Industry Members. Data storage and retention is an internal function 
within CAT and facilitates access to CAT Data by regulatory users of 
CAT, and, therefore, does not directly affect the reporting and other 
requirements applicable to Industry Members. Accordingly, CAT LLC does 
not anticipate that the Data Storage Amendment would have an adverse 
impact on Industry Members or their costs.
iv. The Data Storage Amendment Would Enhance Market Efficiency
    CAT LLC also believes the Data Storage Amendment would enhance the 
efficiency of the securities markets because it would significantly 
reduce costs with limited regulatory impact. Importantly, the amount of 
data reported to CAT and that must be stored by CAT LLC is orders of 
magnitude in excess of that expected at the time that the Plan was 
approved. As noted above, when the CAT NMS Plan was adopted in 2016, it 
was ``expected that the Central Repository will grow to more than 29 
petabytes of raw, uncompressed data.'' \66\ The Plan Processor 
currently projects cumulative storage will be approximately 820 to 830 
petabytes for 2025. As discussed above, the Data Storage Amendment 
would provide significant annual cost savings for CAT LLC. Such cost 
savings would not only benefit CAT LLC, but would also provide cost 
savings for any Participants and Industry Members that are required to 
fund the CAT in accordance with the CAT NMS Plan. Ultimately, such cost 
savings would benefit investors and the U.S. markets as a whole, 
thereby facilitating the goals of the Exchange Act.
---------------------------------------------------------------------------

    \66\ See CAT NMS Plan Approval Order at 85203; Appendix D, 
Section 1.3 of the CAT NMS Plan at Appendix D-5.
---------------------------------------------------------------------------

3. The Late Data Re-Processing Amendment: Elimination of Late Data Re-
Processing
    CAT LLC proposes to amend the CAT NMS Plan to discontinue re-
processing for late or corrected data received after T+4 at 8:00 a.m. 
Eastern Time \67\ (``Late Reported Data'') (the ``Late Data Re-
Processing Amendment''). The Late Data Re-Processing Amendment would 
reduce CAT costs for cloud hosting services by approximately $14-$19 
million annually, plus a $300,000 reduction in the Plan Processor 
annual operating fee, which is accounted for in the Plan Processor 
operating fee discussion above.\68\
---------------------------------------------------------------------------

    \67\ Note that, for purposes of this document, references to 
data received ``after T+5,'' or to post-T+5 data, submissions, or 
reports, are to data received ``after T+4 at 8 a.m. Eastern Time.''
    \68\ See introduction to this filing.
---------------------------------------------------------------------------

    As discussed further below, the Late Data Re-Processing Amendment 
would expand upon the substance of the exemptive relief related to late 
data re-processing granted by the Commission in the 2025 Cost Savings 
Exemptive Order and increases the anticipated cost savings related to 
late data re-processing exemptive relief.\69\ Specifically, the Late 
Data Re-Processing Amendment expands upon the exemptive relief related 
to late data re-processing as set forth in the 2025 Cost Savings 
Exemptive Order by eliminating all late re-processing. The following 
compares the estimated annual cost savings related to late data re-
processing relief granted in the 2025 Cost Savings Exemptive Order and 
the Late Data Re-Processing Storage Amendment. Note that the $14-$19 
million cost savings for the Late Data Re-Processing Amendment includes 
the $12.5-17 million estimated to be achieved though the exemptive 
relief provided by the 2025 Cost Savings Exemptive Order related to 
late data re-processing, an incremental savings of approximately $1.5 
to $2 million.

a. Current CAT NMS Plan Requirements

[[Page 61518]]

    The CAT NMS Plan requires that ``[a]ll CAT Data reported to the 
Central Repository must be processed and assembled to create the 
complete lifecycle of each Reportable Event.'' \70\ The CAT NMS Plan 
sets a deadline of T+3 at 8:00 a.m. Eastern Time for the 
``[r]esubmission of corrected data'' and a deadline of T+5 at 8:00 a.m. 
Eastern Time for the Plan Processor to make ``[c]orrected data 
available to Participant regulatory staff and the SEC.'' \71\ For data 
corrections received after T+5, the CAT NMS Plan specifies that 
``Participants' regulatory staff and the SEC must be notified and 
informed as to how re-processing will be completed.'' \72\ The 
Commission has stated that ``[t]ogether, these sections require the 
Plan Processor to process and assemble any corrected CAT Data received 
after T+5 into complete order event lifecycles and to notify regulatory 
users as to how such re-processing will be completed.'' \73\
---------------------------------------------------------------------------

    \70\ Section 3 of Appendix D of the CAT NMS Plan at D-8. Note, 
however, that OMM Quotes in Listed Options are not subject to any 
linkage requirements. Id. at D-10.

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

b. Exemptive Relief Pursuant to November 2023 Exemptive Order
    In November 2023, the Commission granted conditional exemptive 
relief from the re-processing requirements for corrected data received 
after T+5 that are set forth in Section 3 of Appendix D of the CAT NMS 
Plan and Section 6.2 of the CAT NMS Plan.\74\
---------------------------------------------------------------------------

    \74\ November 2023 Exemptive Order at 77130-31.
---------------------------------------------------------------------------

    The vast majority of lifecycles are complete as of T+5, and the 
vast majority of Late Reported Data does not impact lifecycle 
linkages.\75\ However, in the limited circumstances in which there is a 
missing link between two disjoined segments of an order lifecycle,\76\ 
full re-processing of the entire set of data for each trade for which 
Late Reported Data is received (including assigning a new CAT-Order-ID 
for the entire lifecycle) would be exceedingly costly. Accordingly, the 
Participants developed, and the Commission granted exemptive relief 
permitting, the ``Enhanced Late to the Lifecycle'' process.'' 
Specifically, the exemptive relief provided the following:
---------------------------------------------------------------------------

    \75\ 2025 Cost Savings Exemptive Order at 47856.
    \76\ November 2023 Exemptive Order at 77130.

    The Plan Processor must maintain its implementation of 
functionality related to late data lifecycle association that was 
approved by the Operating Committee on January 14, 2022 (the ``Late 
to the Lifecycle process'') and on September 20, 2022 (the 
``Targeted Replay process'') (collectively, the ``Enhanced Late to 
the Lifecycle process''). Under the Enhanced Late to the Lifecycle 
process, all late records (i.e., records received after T+5) include 
the date of the correction and, if applicable, the record identifier 
of the record being corrected as part of normal re-processing. In 
addition, the late record is now associated with all relevant 
lifecycles as part of normal re-processing, such that order event 
lifecycles may now be associated with more than one CAT Order 
ID.\77\
---------------------------------------------------------------------------

    \77\ Id. Prior to the implementation of this functionality, in 
the limited circumstances in which there was a missing link between 
two disjoined segments of an order lifecycle, new or corrected data 
would join only one of the pre-existing segments and would be 
assigned to only one of the relevant lifecycle CAT-Order-IDs for the 
disjoined segment and evaluated for further re-processing.

    The Commission further required, as a condition to the November 
2023 exemptive relief, that the Participants implement so-called ``Full 
Replay'' functionality. ``Full Replay'' presents post-T+5 data in a 
manner substantially similar to how such data would have been 
represented if it had been reported prior to T+5, including by 
replicating and replaying records with enrichments impacted by post-T+5 
submissions, creating updated enrichments, and persisting the 
replicated records within the underlying data. Specifically, the 
exemptive relief provided the following:
    <bullet> The following functionality must be fully implemented and 
made available to regulatory users:
    [cir] Functionality that creates a lifecycle mapping which 
indicates all lifecycle associations made during the Enhanced Late to 
the Lifecycle process;
    [cir] Functionality that presents to regulatory users post-T+5 data 
in a manner substantially similar to how such data would have been 
represented if it had been reported prior to T+5, including by 
replicating and replaying records with enrichments impacted by post-T+5 
submissions, creating updated enrichments, and persisting the 
replicated records within the underlying data (the ``Full Replay 
process''); and
    [cir] Functionality that enhances the OTQT, including the ability 
to include or exclude any records that were created or replaced as a 
result of the Full Replay process.
    Such functionality must be fully implemented and made available to 
regulatory users within twelve months of the change order's approval by 
the Participants.
    <bullet> The Plan Processor must schedule the Enhanced Late to the 
Lifecycle process and the Full Replay process to run weekly, such that 
late reported data received through Friday of the prior week are 
available for regulatory users on the following business day at 8 a.m. 
Eastern Time, absent extraordinary circumstances, for data within the 
prior 18 months. For data outside of this 18-month window, the 
Participants must schedule the Enhanced Late to the Lifecycle process 
and the Full Replay process to run no less frequently than 
quarterly.\78\
---------------------------------------------------------------------------

    \78\ Id.
---------------------------------------------------------------------------

    The cost of implementing the ``Full Replay'' functionality required 
by the Commission included $1.76 million in one-time costs, $360,000 in 
recurring annual Plan Processor operating fees. In addition, the 
functionality has led to millions of dollars each year in ongoing cloud 
hosting services fees. For example, in the six months following 
implementation of the ``Full Replay'' process required by the 
Commission, total production costs associated with late data processing 
were $7.16 million, reaching a high monthly cost of $1.6 million in May 
2025--more than 18% of the overall cloud costs for May 2025. Since the 
start of 2025, only 1% of the overall linkable volume processed by the 
Central Repository required re-processing. Accordingly, the millions of 
dollars in costs associated with re-processing a relatively small 
percentage of overall CAT Data are disproportionately significant and 
continue to far outweigh the regulatory benefit.
c. Conditional Exemptive Relief Regarding Late Data Re-Processing 
Pursuant to 2025 Cost Savings Exemptive Order
    Recognizing that ``these relaxed requirements were extremely costly 
to implement even for a relatively limited amount of CAT Data,'' \79\ 
the Commission granted in its 2025 Cost Savings Exemptive Order 
``conditional exemptive relief to allow the Participants to further 
reduce requirements related to the re-processing of late records.'' 
\80\ Specifically, the Commission granted conditional exemptive relief 
from the re-processing requirements for late records in Sections 3, 
6.1, and 6.2 of Appendix D of the CAT NMS Plan, subject to the 
following conditions:
---------------------------------------------------------------------------

    \79\ 2025 Cost Savings Exemptive Order at 47856.
    \80\ Id.
---------------------------------------------------------------------------

    <bullet> The Plan Processor must maintain its implementation of the 
above-described Enhanced Late to the Lifecycle process for late records 
from trade dates within the prior 3 years. For data outside of this 3-
year window, no re-processing is required.
    <bullet> For all late records, the Plan Processor must run the 
above-described

[[Page 61519]]

Enhanced Late to the Lifecycle process no less frequently than 
quarterly.
    <bullet> The Plan Processor must maintain the above-described 
functionality that creates a lifecycle mapping which indicates all 
lifecycle associations made during the Enhanced Late to the Lifecycle 
process.
    <bullet> Upon requests made by authorized regulatory users from the 
Participants or the Commission, the Plan Processor must perform the 
Full Replay process on specified data, such that late records received 
through Friday of the prior week are available for regulatory users on 
the following business day at 8 a.m. Eastern Time, absent extraordinary 
circumstances.
    <bullet> For late records received after T+5 at 8 a.m. Eastern 
Time, the Plan Processor must continue to notify regulatory users how 
re-processing will be completed.\81\
---------------------------------------------------------------------------

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

    This conditional exemptive relief is intended to supersede the 
conditional exemptive relief set forth in the November 2023 Exemptive 
Order with respect to re-processing of data received after T+5.\82\
---------------------------------------------------------------------------

    \82\ Id.
---------------------------------------------------------------------------

    The Commission stated the following in support of its exemptive 
relief:

    The Commission understands from communications with the 
Participants that most order event lifecycles would be unaffected by 
the conditional exemptive relief granted herein--the vast majority 
of order event lifecycles are currently completed on time, and the 
vast majority of late-reported data does not impact lifecycle 
linkages. For the less than 1% of late-reported data that does 
require additional re-processing to construct an order event 
lifecycle, requiring the Participants to run the Enhanced Late to 
the Lifecycle process quarterly for trade dates within the prior 3 
years should still provide regulatory users with the ability to 
quickly and reliably identify and link all relevant lifecycles 
associated with the late-reported data that is most frequently 
needed and accessed by regulatory users. Although this approach 
requires some manual intervention by regulatory users, the 
Commission believes this is a reasonable trade-off for the millions 
of dollars of cost savings the Commission expects will likely flow 
from significantly reducing the usage of the Full Replay process and 
any additional costs savings that may be realized from requiring the 
Plan Processor to perform the Enhanced Late to the Lifecycle process 
quarterly instead of weekly. Moreover, under the conditional 
exemptive relief granted herein, regulatory users will be able to 
request that the Plan Processor perform the Full Replay process on 
specified data, which should continue to enable regulatory users to 
react to major market events in an effective and expeditious way.
d. Proposed Revisions to the CAT NMS Plan
    With the Late Data Re-Processing Amendment, Late Reported Data 
would not be subject to any re-processing and would be added to the 
audit trail without any lifecycle enrichments. Specifically, CAT LLC 
proposes to discontinue all Enhanced Late to the Lifecycle and all Full 
Replay re-processing.\83\ To eliminate the requirement to re-process 
Late Reported Data, CAT LLC proposes to revise Section 6.2 of Appendix 
D of the CAT NMS Plan, which currently states, in relevant part:
---------------------------------------------------------------------------

    \83\ CAT LLC understands that, with this proposed change, the 
Plan Processor would retain the ability to perform Late to the 
Lifecycle and Full Replay re-processing on an ad hoc basis if 
required for regulatory purposes. CAT LLC understands that there 
would be no material impact to FINRA CAT's proposed operating fees 
to maintain the functionality, as it is an extension of other 
required system elements (e.g., linkage). The only ongoing cost for 
any such ad hoc processing of Late Reported Data would be due to 
incremental cloud hosting fees associated with each ad hoc 
processing request.

    If corrections are received after T+5, Participants' regulatory 
staff and the SEC must be notified and informed as to how re-
processing will be completed. The Operating Committee will be 
involved with decisions on how to re-process the data; however, this 
does not relieve the Plan Processor of notifying the Participants' 
---------------------------------------------------------------------------
regulatory staff and the SEC.

    CAT LLC proposes to amend Section 6.2 of Appendix D of the CAT NMS 
Plan to modify the re-processing requirements for data received after 
T+5. CAT LLC proposes to revise Section 6.2 of Appendix D of the CAT 
NMS Plan to state that ``[n]otwithstanding any other requirements of 
the CAT NMS Plan, or the Exchange Act or the rules and regulations 
thereunder, records received after T+4 at 8:00 a.m. Eastern Time will 
not be subject to any re-processing and will be added to the audit 
trail without any lifecycle enrichments.'' This change also clarifies 
that the cut-off time is T+4 at 8:00 a.m. Eastern Time, rather than 
T+5. Correspondingly, CAT LLC proposes to remove the requirement that, 
``[i]f corrections are received after T+5, Participants' regulatory 
staff and the SEC must be notified and informed as to how re-processing 
will be completed.'' In addition, CAT LLC proposes to remove from 
Section 6.2 of Appendix D of the CAT NMS Plan the statement that 
``[t]he Operating Committee will be involved with decisions on how to 
re-process the data; however, this does not relieve the Plan Processor 
of notifying the Participants' regulatory staff and the SEC.''
    As revised, the relevant portion of Section 6.2 of Appendix D would 
read as follows:

    Notwithstanding any other requirements of the CAT NMS Plan, or 
the Exchange Act or the rules and regulations thereunder, records 
received after T+4 at 8:00 a.m. Eastern Time will not be subject to 
any re-processing and will be added to the audit trail without any 
lifecycle enrichments.

    With this proposed change, the Plan Processor will continue to 
provide data regarding late submissions to CAT Reporters and 
regulators. The Plan Processor will continue to make available summary 
statistics on late submission through its report card program.\84\ 
Additionally, FINRA CAT will continue to publish detailed information 
regarding late submissions and other issues to regulators through its 
data issue search system, and to send summary emails describing new 
data issues to all query tool users on a weekly basis.\85\ Finally, the 
distinction between trade date and submission date continues to be 
available on a record-by-record basis within the Central Repository. 
Accordingly, regulators can identify and review late data submissions 
by leveraging summary statistics provided by the Plan Processor, by 
reviewing the catalog of data issues updated daily in the data issue 
search system, and by reviewing the underlying records themselves.
---------------------------------------------------------------------------

    \84\ See Section 10.4 of Appendix D of the CAT NMS Plan 
(requiring compliance report cards to include the ``[n]umber of 
transactions submitted later than reporting deadlines'').
    \85\ See Appendix C of the CAT NMS Plan at C-12.
---------------------------------------------------------------------------

e. The Benefits of the Late Data Re-Processing Amendment Significantly 
Outweigh Its Costs
    CAT LLC believes that the anticipated savings associated with the 
Late Data Re-Processing Amendment would substantially outweigh the 
limited regulatory impact on the CAT. The Late Data Re-Processing 
Amendment would allow CAT LLC to achieve an estimated $14-$19 million 
in annual cost savings for cloud hosting services, which would 
materially advance CAT LLC's ongoing efforts to reduce CAT operating 
costs. Moreover, these cost reductions would not adversely affect the 
regulatory purposes of the CAT.
i. The Late Data Re-Processing Amendment Would Result in an Estimated 
$14-$19 Million in Annual Cost Savings for Cloud Hosting Services
    CAT LLC, after consultation with the Plan Processor, has determined 
that eliminating Late Data Re-Processing would allow CAT LLC to achieve

[[Page 61520]]

approximately $14-$19 million in annual cost savings in cloud hosting 
services. These cost savings estimates are based on certain assumptions 
and the current scope of the CAT, and may vary based on, among other 
things, the details of the requirements in any final amendment approved 
by the Commission.\86\
---------------------------------------------------------------------------

    \86\ See supra notes 9 and 10.
---------------------------------------------------------------------------

    To implement the proposal, the Plan Processor has proposed a one-
time change request implementation fee of approximately $250,000 to 
$500,000. The Plan Processor estimates that it would take approximately 
two to four months to fully implement the changes for the Late Data Re-
Processing Amendment. One-time implementation costs will generally 
consist of Plan Processor labor costs associated with coding and 
software development, as well as any related cloud fees associated with 
the development, testing, and load testing of the proposed changes for 
the proposed amendment. Even accounting for this one-time 
implementation cost, the proposal would allow CAT LLC to achieve 
substantial cost savings in the first year.
    Although only a small portion of CAT Data is Late Reported Data, 
the costs of the re-processing of such data are disproportionately 
significant. CAT LLC does not believe that the significant costs of 
linking such a small percentage of the overall CAT Data are 
justified.\87\
---------------------------------------------------------------------------

    \87\ During the period from May 2025 through October 2025: (1) 
late reprocessing, including Full Replay processing, represented 
approximately 31% of compute costs (approximately $5.5 million); (2) 
of that 31%, Full Replay processing accounts for 57% (approximately 
$3.2 million). The Plan Processor ceased Full Replay processing in 
November 2025 and has observed a 50% reduction in late processing-
related costs from 31% to 15% of the total monthly compute cost 
(where compute costs for late processing in November 2025 were 
approximately $400,000 compared to $1 million in May).
---------------------------------------------------------------------------

ii. The Late Data Re-Processing Amendment Would Preserve the Core 
Regulatory Purposes of the CAT
    CAT LLC further believes that the Late Data Re-Processing Amendment 
would have limited regulatory impact. All Participants believe that 
this approach would be sufficient for their regulatory purposes and is 
vastly preferable to routinely incurring the current, significant costs 
of regular, automated re-processing.
    CAT LLC has had substantial experience with the reporting of CAT 
Data for several years now. Based on such experience, CAT LLC has seen 
substantial compliance with the CAT reporting timelines.\88\ For 
example, in the past year, only 0.82% of Reportable Events were 
reported late, and only 0.07% of Reportable Events required re-
processing. In addition, the following provides the percentage of late 
reports through the first ten months of 2025 for (1) new records and 
(2) corrections \89\ and repairs \90\ for each indicated time period:
---------------------------------------------------------------------------

    \88\ Each of the Participants require their members to report 
CAT Data to the CAT in a timely matter. See, e.g., FINRA Rule 6893, 
which states that ``Industry Members are required to record and 
report data to the Central Repository as required by this Rule 
Series in a manner that ensures the timeliness, accuracy, integrity 
and completeness of such data.'' Such rule requirements have been 
enforced through disciplinary actions for failure to timely report 
CAT Data. See, e.g., Instinet, LLC, FINRA Case No. 2020067139101, 
Aug. 16, 2023.
    \89\ ``Corrections'' refer to reporting errors self-identified 
by CAT Reporters that are repaired and re-submitted. See CAT 
Reporting Technical Specifications for Industry Members at 364-65 
(Nov. 12, 2025), <a href="https://www.catnmsplan.com/sites/default/files/2025-11/11.14.25_CAT_Reporting_Technical_Specifications_for_Industry_Members_v4.1.0r12_CLEAN.pdf">https://www.catnmsplan.com/sites/default/files/2025-11/11.14.25_CAT_Reporting_Technical_Specifications_for_Industry_Members_v4.1.0r12_CLEAN.pdf</a> (``Errors found during CAT processing and found 
by CAT Reporters subsequent to transmission must be repaired . . . 
Corrections may be reported for any previously submitted event'').
    \90\ ``Repairs'' refer to reporting errors identified by the 
Plan Processor during the data validation process that must be 
repaired and re-submitted by CAT Reporters. See CAT Reporting 
Technical Specifications for Industry Members at 365 (Nov. 12, 
2025), <a href="https://www.catnmsplan.com/sites/default/files/2025-11/11.14.25_CAT_Reporting_Technical_Specifications_for_Industry_Members_v4.1.0r12_CLEAN.pdf">https://www.catnmsplan.com/sites/default/files/2025-11/11.14.25_CAT_Reporting_Technical_Specifications_for_Industry_Members_v4.1.0r12_CLEAN.pdf</a> (``A repair is instructed when repairing events 
for which a CAT Error was provided in feedback.'').

------------------------------------------------------------------------
                                       New records      Corrections &
              Reported                     (%)           repairs (%)
------------------------------------------------------------------------
By T+4 8 a.m........................         99.72                  3.49
Between T+4 and T+10................          0.05                  0.78
Between T+10 and T+30...............          0.02                  0.53
Between T+30 and T+60...............          0.20                  1.08
Beyond T+60.........................          0.00                 94.12
------------------------------------------------------------------------

    The chart demonstrates that the vast majority of first-time 
``late'' data (99.72%) is reported by T+4 8 a.m. When firms submit 
repairs and corrections, most of the corrections and repairs (94.2%) 
are submitted beyond T+60. This data indicates that changes to feedback 
timing would not dramatically impact how regulators perceive CAT Data 
when measured in the aggregate.
    Moreover, Late Reported Data would continue to be ingested by the 
CAT, and, therefore, it would continue to be available to regulators if 
necessary.
iii. The Late Data Re-Processing Amendment Would Not Adversely Impact 
Industry Members
    CAT LLC also believes that the Late Data Re-Processing Amendment 
would reduce costs with limited regulatory impact without having an 
adverse impact on Industry Members. Late data re-processing is an 
internal function within CAT, and, therefore, does not directly affect 
the reporting and other requirements applicable to Industry Members. 
Industry Members are currently subject to regulatory requirements to 
report CAT Data in a timely manner.\91\ This proposed amendment does 
not change that requirement in any fashion. Accordingly, CAT LLC does 
not anticipate that the Late Data Re-Processing Amendment would have an 
adverse impact on Industry Members' reporting or their costs.
---------------------------------------------------------------------------

    \91\ See supra, note 85.
---------------------------------------------------------------------------

    Furthermore, based on discussions with the Participants, CAT LLC 
does not believe that the Late Data Re-Processing Amendment would lead 
to material increases in Electronic Blue Sheet or other follow-up 
requests to confirm the data for investigations or enforcement actions.
iv. The Late Data Re-Processing Amendment Would Enhance Market 
Efficiency
    CAT LLC also believes that the Late Data Re-Processing Amendment 
would enhance the efficiency of the securities markets. Late data re-
processing is an internal function within CAT, and, therefore, does not 
directly affect the requirements applicable to CAT Reporters. As 
discussed above, however, the Late Data Re-Processing Amendment would 
provide significant cost savings for CAT LLC. Such cost savings would 
not only benefit CAT LLC, but they would also benefit any Participants 
and Industry Members that are required to fund the CAT in accordance 
with the

[[Page 61521]]

CAT NMS Plan. Ultimately, such cost savings would benefit investors and 
the U.S. markets as a whole, thereby facilitating the goals of the 
Exchange Act.
4. OTQT Amendment: Elimination of Online Targeted Query Tool (OTQT)
    CAT LLC proposes to amend the CAT NMS Plan to eliminate the 
requirement to provide an online targeted query tool (``OTQT'') (the 
``OTQT Amendment''). The OTQT Amendment would reduce CAT cloud hosting 
services costs by approximately $2.5-$3.5 million annually.
    The OTQT Amendment is consistent with and would codify the 
exemptive relief related to the OTQT as set forth in the 2025 Cost 
Savings Exemptive Order.'' \92\ Correspondingly, the estimated cost 
savings for the OTQT Amendment are the same as expected with regard to 
the implementation of the exemptive relief related to the OTQT in the 
2025 Cost Savings Exemptive Order. The following compares the estimated 
annual cost savings for the exemptive relief related to the OTQT in the 
2025 Cost Savings Exemptive Order and the OTQT Amendment.

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

a. Current CAT NMS Plan Requirements
    Section 6.10(c)(i) of the CAT NMS Plan requires the Plan Processor 
to provide the Participants and the Commission with access to processed 
CAT Data through an OTQT. Section 6.10(c)(i)(A) of the CAT NMS Plan 
provides: ``The online targeted query tool will provide authorized 
users with the ability to retrieve CAT Data via an online query screen 
that includes the ability to choose from a variety of pre-defined 
selection criteria. Targeted queries must include date(s) and/or time 
range(s), as well as one or more of a variety of fields.'' Section 8.1, 
including Sections 8.1.1-8.1.3, of Appendix D of the CAT NMS Plan sets 
forth certain performance requirements for the OTQT, including 
timeframes by which results must be returned for various types of 
queries.
    In connection with the settlement of litigation brought by the 
Participants, in November 2023, the Commission granted conditional 
relief from the OTQT performance requirements, subject to the OTQT 
satisfying the performance requirements set forth in the November 2023 
Exemptive Order.\94\
---------------------------------------------------------------------------

    \94\ See November 2023 Exemptive Order.
---------------------------------------------------------------------------

b. Conditional Exemptive Relief Regarding OTQT Pursuant to 2025 Cost 
Savings Exemptive Order
    In its 2025 Cost Savings Exemptive Order, the Commission granted 
conditional exemptive relief from the requirements for DIVER, ARLE, OLA 
Viewer, and MIRS volume concentration and market replay tools. 
Specifically, for these tools, the Commission granted conditional 
exemptive relief from the above-described provisions in the CAT NMS 
Plan directing the Participants to maintain an OTQT and setting forth 
performance requirements for the OTQT, subject to certain conditions. 
The conditional exemptive relief granted in the 2025 Cost Savings 
Exemptive Order supersedes the conditional exemptive relief set forth 
in the November 2023 Exemptive Order with respect to OTQT performance 
standards. In providing this exemptive relief, the Commission stated 
that it ``understands, based on communications with the Participants, 
that elimination of the OTQT will generate meaningful cost savings, and 
the Commission does not believe that elimination of the OTQT 
functionality would unduly impact regulators' oversight of the 
markets.'' \95\ The SEC stated in the 2025 Cost Savings Exemptive Order 
that this exemptive relief regarding the OTQT functionality was 
anticipated to reduce CAT cloud hosting services costs by approximately 
$2.35-$2.85 million annually.\96\
---------------------------------------------------------------------------

    \96\ Id. at 47857, n.46.
---------------------------------------------------------------------------

c. Proposed Revisions to CAT NMS Plan
    With the OTQT Amendment, CAT LLC would propose to amend the CAT NMS 
Plan to eliminate the requirement to provide the OTQT.\97\ The OTQT 
Amendment would be consistent with the exemptive relief related to the 
OTQT as set forth in the 2025 Cost Savings Exemptive Order, and, 
therefore, the OTQT Amendment would incorporate the estimated $2.5-$3.5 
million annual reduction in cloud hosting services costs into the Plan. 
To eliminate the requirement that regulators be provided with access to 
CAT Data through the OTQT from the CAT NMS Plan, CAT LLC proposes to 
make the following changes to the CAT NMS Plan.
---------------------------------------------------------------------------

    \97\ As a part of the elimination of the OTQT, the Plan 
Processor also would schedule for deletion any copies of data 
produced solely for access via OTQT or to meet OTQT performance 
requirements (e.g., DIVER-optimized copies of IM Event data and OLA 
Events, which would no longer be accessible following the removal of 
DIVER).
---------------------------------------------------------------------------

i. Section 6.10(c) of the CAT NMS Plan
    CAT LLC proposes to amend Section 6.10(c) of the CAT NMS Plan to 
eliminate the requirement to provide access to CAT Data via the OTQT. 
The introductory paragraph in Section 6.10(c) of the CAT NMS Plan 
states:

    Consistent with Appendix D, Functionality of the CAT System, the 
Plan Processor shall provide Participants and the SEC with access to 
all CAT Data stored in the Central Repository. Regulators will have 
access to processed CAT Data through two different methods; an 
online targeted query tool, and user-defined direct queries and bulk 
extracts.

    CAT LLC proposes to delete from this provision the reference to 
``two different methods'' and the reference to ``an online targeted 
query tool.''
    In addition, CAT LLC proposes to delete paragraph (A) of Section 
6.10(c)(i) of the CAT NMS Plan and replace it with a ``Reserved'' 
designation. Paragraph (A) currently states:

    The online targeted query tool will provide authorized users 
with the ability to retrieve CAT Data via an online query screen 
that includes the ability to choose from a variety of pre-defined 
selection criteria. Targeted queries must include date(s) and/or 
time range(s), as well as one or more of a variety of fields.
ii. Appendix D of the CAT NMS Plan
    CAT LLC also proposes deleting certain sections of Appendix D of 
the

[[Page 61522]]

CAT NMS Plan that address requirements related to the OTQT.
    CAT LLC proposes to delete Section 8.1.1 of Appendix D (``Online 
Targeted Query Tool'') and Section 8.1.2 of Appendix D (``Online 
Targeted Query Tool Performance Requirements'') in their entirety and 
to redesignate these sections as ``Reserved.''
    CAT LLC proposes to revise the title of Section 8.1.3 of Appendix 
D, which reads ``Online Targeted Query Tool Access and Administration'' 
to delete the reference to the ``Online Targeted Query Tool Access,'' 
and clarify the reference to Administration by revising the title to 
read ``Administration of Regulatory Access.'' In addition, CAT LLC 
proposes to delete the following sentence including the reference to 
the OTQT: ``PII data must not be available via the online targeted 
query tool or the user-defined direct query interface.''
    CAT LLC proposes to revise Section 8.2 of Appendix D to remove the 
sentence that currently states that ``[t]he CAT System must contain the 
same level of control, monitoring, logging and reporting as the online 
targeted query tool.'' The deletion of this sentence does not affect 
the comparable requirements related to user-defined direct queries or 
bulk extracts, as the requirement being deleted is repetitive of 
requirements regarding control, monitoring, logging and reporting set 
forth in Section 8.2.2 of Appendix D of the CAT NMS Plan.
    Finally, CAT LLC also proposes to delete other remaining references 
to the OTQT from Appendix D of the CAT NMS Plan, including from 
Sections 3.4, 8.1, and 8.4. These amendments are set forth in Exhibit 
A.
d. The Benefits of the OTQT Amendment Significantly Outweigh Its Costs
i. The OTQT Amendment Would Result in an Estimated $2.5-$3.5 Million in 
Annual Cost Savings for Cloud Hosting Services
    CAT LLC, after consultation with the Plan Processor, has determined 
that eliminating the OTQT, as permitted pursuant to the 2025 Cost 
Savings Exemptive Order and as described in this OTQT Amendment, would 
allow CAT LLC to achieve a total of approximately $2.5-$3.5 million in 
annual cost savings for cloud hosting services. These cost savings 
estimates are based on certain assumptions and the current scope of the 
CAT, and may vary based on, among other things, the details of the 
requirements in any final amendment approved by the Commission.\98\
---------------------------------------------------------------------------

    \98\ See supra, notes 9 and 10.
---------------------------------------------------------------------------

    To implement the proposal, the Plan Processor has proposed a one-
time change request implementation fee of approximately $135,000. The 
Plan Processor estimates that it would take approximately eight to ten 
weeks to fully implement the changes for the OTQT Amendment. One-time 
implementation costs will generally consist of Plan Processor labor 
costs associated with coding and software development, as well as any 
related cloud fees associated with the development, testing, and load 
testing of the proposed changes for the proposed amendment. Even 
accounting for this one-time implementation cost, the proposal would 
allow CAT LLC to achieve substantial cost savings in the first full 
year.
ii. The OTQT Amendment Would Preserve the Core Regulatory Purposes of 
the CAT
    CAT LLC further believes that this OTQT Amendment would have 
limited regulatory impact. Based on the current regulatory use of the 
OTQT, CAT LLC has determined that the elimination of the OTQT would not 
adversely affect market oversight.
    First, as the SEC noted in the 2025 Cost Savings Exemptive Order, 
``[t]he elimination of OTQT functionality would not in any way impact 
the underlying CAT Data that is made available to regulators.'' \99\ 
The proposed change only would affect the manner in which CAT Data is 
accessed by regulatory users at the SEC and the Participants.
---------------------------------------------------------------------------

    \99\ 2025 Cost Savings Exemptive Order at 47857.
---------------------------------------------------------------------------

    Second, the Participants and the Commission agree that their 
regulatory programs would not be impaired by the loss of the OTQT 
functionality. Section 6.10(c)(i) of the CAT NMS Plan requires the Plan 
Processor to provide Participants and the SEC with access to CAT Data 
through two different methods in addition to the OTQT: (1) user-defined 
direct queries; and (2) bulk extracts. Currently, the user-defined 
query tool is ``BDSQL,'' and the bulk extract tool is ``Direct Read.'' 
The ``BDSQL'' and ``Direct Read'' interfaces represent significantly 
more sophisticated and cost-efficient methods of providing access to 
CAT Data than the OTQT. The Participants unanimously agree that each of 
their regulatory groups would be able to conduct their regulatory 
programs using only BDSQL and Direct Read, and could otherwise adjust 
by creating and operating, or continuing to operate, their own internal 
tools to replicate the queries they would otherwise run on the 
OTQT.\100\ In addition, having regulators develop and use their own 
bespoke and diverse tools could promote innovation as opposed to every 
regulator being wed to the same tool.
---------------------------------------------------------------------------

    \100\ The SEC recognized this point in the 2025 Cost Savings 
Exemptive Order. 2025 Cost Savings Exemptive Order at 47857. See 
also 2024 Cost Savings Amendment Approval Order at 103038, 103050.
---------------------------------------------------------------------------

    In the 2025 Cost Savings Exemptive Order, the Commission stated 
that ``[t]he Commission likewise believes that its own regulatory 
program would not be impaired by the loss of certain OTQT 
functionality.'' \101\ The Commission explained that the ``Staff 
already have the necessary skill sets to use the BDSQL and Direct Read 
tools, which will be maintained by the Plan Processor, and the 
Commission has already developed internal tools that replicate 
functionality supplied by the DIVER, ARLE, OLA Viewer, and MIRS volume 
concentration and market replay tools that may not be available if the 
Participants utilize this exemptive relief.'' \102\ As a result, the 
Commission determined to provide conditional exemptive relief with 
regard to the requirement to provide the OTQT.

iii. The OTQT Amendment Would Not Adversely Impact Industry Members
    CAT LLC also believes that the OTQT Amendment would reduce costs 
with limited regulatory impact without having an adverse impact on 
Industry Members. The OTQT is an internal function within CAT and a 
tool available for use by regulatory users of CAT, and, therefore, does 
not directly affect the reporting and other requirements applicable to 
Industry Members. Accordingly, CAT LLC does not anticipate that the 
OTQT Amendment would have an adverse impact on Industry Members or 
their costs.
iv. The OTQT Amendment Would Enhance Market Efficiency
    CAT LLC also believes that the OTQT Amendment would enhance the 
efficiency of the securities markets because it would reduce costs with 
limited regulatory impact. As discussed above, the OTQT Amendment would 
provide significant annual cost savings for CAT LLC. Such cost savings 
would not only benefit CAT LLC, but also would provide cost savings for 
any Participants and Industry Members that are required to fund the CAT 
in accordance with the CAT NMS Plan. Ultimately, such cost savings 
would benefit investors and the U.S. markets as

[[Page 61523]]

a whole, thereby facilitating the goals of the Exchange Act.
    In addition, CAT LLC does not believe that the OTQT Amendment would 
adversely affect market efficiency because it understands that the 
Participants have already built their own tools to use in place of the 
OTQT, or rely on other Participants that have done so. Accordingly, the 
OTQT Amendment would only enhance efficiency by removing redundant 
regulatory systems from the market. In addition, reliance on tools that 
are tailored to the needs of the various regulators also would enhance 
efficiency, rather than relying on one uniform tool for all regulators. 
Moreover, the OTQT Amendment does not propose to change the other means 
provided by the CAT for accessing CAT Data (e.g., bulk extract).
5. Rejected Message Amendment: Elimination of Participant Reporting of 
Rejected Messages
    CAT LLC proposes to amend the CAT NMS Plan to eliminate the 
requirement for Participants to report rejected order messages (the 
``Rejected Message Amendment''). The Rejected Message Amendment would 
reduce CAT costs for cloud hosting services by approximately $500,000 
annually.
    The 2025 Cost Savings Exemptive Order did not address rejected 
messages. Accordingly, the estimated cost savings of approximately 
$500,000 annually are over and above the cost savings allowed via the 
2025 Cost Savings Exemptive Order.
a. Current CAT NMS Plan Requirements
    Section 6.3(d)(i) of the CAT NMS Plan requires Participants to 
``record and electronically report to the Central Repository'' certain 
information for ``each order and each Reportable Event,'' including 
``for original receipt or origination of an order.'' The CAT NMS Plan 
specifies that ``order'' has ``the meaning set forth in Rule 
613(j)(8),'' \103\ which further defines ``order'' to include: ``(i) 
[a]ny order received by a member of a national securities exchange or 
national securities association from any person; (ii) [a]ny order 
originated by a member of a national securities exchange or national 
securities association; or (iii) [a]ny bid or offer.'' The SEC has 
stated the following regarding these provisions:
---------------------------------------------------------------------------

    \103\ Section 1.1 of the CAT NMS Plan.

    These provisions require the Participants to report all orders 
that are ``received,'' not just those orders that are ``received and 
successfully processed by the matching engine,'' those orders that 
are ``received and accepted,'' and/or those orders that are 
``received and assigned an order ID''; the reporting requirement is 
not conditioned on how a Participant acts on an order that is 
received. For example, if a Participant receives a message that 
contains all of the terms necessary for an order to be executed, 
that message still constitutes a ``received'' order that must be 
reported pursuant to the provisions of Section 6.3(d) of the CAT NMS 
Plan regardless of whether it is subsequently rejected. Moreover, as 
``CAT Data,'' rejected orders must also be ``processed and assembled 
to create the complete lifecycle of each Reportable Event'' under 
Appendix D, Section 3 of the CAT NMS Plan.\104\
---------------------------------------------------------------------------

    \104\ July 2022 Exemptive Order at 42256.

    The Commission recognized that ``the Participants continue to 
disagree with its interpretation of these requirements and challenge 
the feasibility of strict compliance with that interpretation.'' \105\
---------------------------------------------------------------------------

    \105\ November 2023 Exemptive Order at 77132 n.33.
---------------------------------------------------------------------------

b. Conditional Exemptive Relief Regarding Rejected Messages Pursuant to 
November 2023 Exemptive Order
    In connection with the settlement of litigation brought by the 
Participants, in November 2023, the Commission granted conditional 
exemptive relief from the requirements set forth in Rule 613(c)(7), 
Section 6.3(d)(i) of the CAT NMS Plan, and Appendix D, Section 3 of the 
CAT NMS Plan relating to Participant reporting of rejected orders and 
subsequent linkage of such orders, subject to the below 
conditions.\106\ The Commission stated that this relief ``does not 
resolve the parties' interpretive disagreement on this issue, but 
instead provides exemptive relief that renders resolution of the issue 
unnecessary.'' \107\
---------------------------------------------------------------------------

    \106\ Id at 77132.
    \107\ Id. at 77132 n.33. The SEC has addressed rejected orders 
in prior exemptive orders as well. See July 2022 Exemptive Order at 
42256-57.
---------------------------------------------------------------------------

    <bullet> The Participants must maintain or improve their existing 
reporting of orders that are received and subsequently rejected, 
including maintenance by Participants of any existing reporting or 
linkage of the keys necessary for the linkage processing specified 
below. The Plan Processor must maintain its existing validations of 
such orders.
    <bullet> The Participants must approve a change order to adopt the 
below-described functionality no later than 60 days following the 
effective date of this Order:
    [cir] Functionality that will attempt ``forward lifecycle linkage'' 
processing, including all enrichments currently provided for other 
order events, of Industry Member MEOR, MOOR, and MEMR Order Route 
events containing a routeRejectedFlag populated as ``true'' with their 
corresponding Participant Reject Message events described in the 
Participant Technical Specifications in instances where the keys 
necessary for such linkage are available (i.e., Symbol (or Option ID), 
RoutingParty, RoutedOrderID, Session). Such functionality must be fully 
implemented and made available to regulatory users within twelve months 
of the change order's approval by the Participants.
    The Participant Technical Specifications reflect the exemptive 
relief provided in the 2023 November 2023 Exemptive Order.\108\
---------------------------------------------------------------------------

    \108\ See Section 3.7.4 of the Participant Technical 
Specifications (Reject Message Event).
---------------------------------------------------------------------------

c. Proposed Revisions to CAT NMS Plan
    With the Rejected Message Amendment, CAT LLC proposes to amend the 
CAT NMS Plan to eliminate the requirement for Participants to report 
rejected order messages to the CAT. The Rejected Message Amendment 
would reduce CAT cloud hosting services costs by approximately $500,000 
annually. To implement the Rejected Message Amendment, CAT LLC proposes 
to add paragraph (h) to Section 6.3 of the CAT NMS Plan, which would 
state the following:

    Rejected Messages. Notwithstanding any provision of the CAT NMS 
Plan (including Appendix D) or the Exchange Act, no Participant 
shall be required to record and electronically report to the Central 
Repository any order rejected by the Participant nor any Reportable 
Events related to such rejected order. For the avoidance of doubt, 
an order that is received by the Participant but not accepted by the 
Participant is an order rejected by the Participant for purposes of 
this paragraph.
d. The Benefits of the Rejected Message Amendment Significantly 
Outweigh Its Costs
i. The Rejected Message Amendment Would Result in an Estimated $500,000 
in Annual Cost Savings for Cloud Hosting Services
    CAT LLC, after consultation with the Plan Processor, has determined 
that eliminating the requirement for Participants to report rejected 
order messages would allow CAT LLC to achieve approximately $500,000 in 
cost savings for cloud services annually. This cost savings estimate is 
based on certain assumptions and the current scope of the CAT, and may 
vary based on, among other things, the details of the requirements in 
any final amendment approved by the Commission.\109\ In addition, the

[[Page 61524]]

Participants estimate that the Rejected Message Amendment would provide 
material cost savings for the Participants collectively as well.
---------------------------------------------------------------------------

    \109\ See supra notes 9 and 10.
---------------------------------------------------------------------------

    To implement the proposal, the Plan Processor has proposed a one-
time change request setting forth an implementation fee of 
approximately $75,000 to $150,000. The Plan Processor estimates that it 
would take approximately two to four months to fully implement the 
changes for the Rejected Message Amendment. One-time implementation 
costs will generally consist of Plan Processor labor costs associated 
with coding and software development, as well as any related cloud fees 
associated with the development, testing, and load testing of the 
proposed changes for the proposed amendment. Even accounting for this 
one-time implementation cost, the proposal would allow CAT LLC to 
achieve substantial cost savings in the first year.
ii. The Rejected Message Amendment Would Preserve the Core Regulatory 
Purposes of the CAT
    CAT LLC believes that the Rejected Message Amendment would have 
limited regulatory impact. Based on the current regulatory use of the 
CAT, CAT LLC has determined that the elimination of the reporting of 
rejected messages would not adversely affect market oversight. CAT LLC 
understands that the Participants have not used rejected message data 
reported for regulatory purposes to date. Accordingly, the data 
collected with respect to such messages may be of little beneficial use 
to regulators.
iii. The Rejected Message Amendment Would Not Adversely Impact Industry 
Members
    CAT LLC also believes that the Rejected Message Amendment would 
reduce costs with limited regulatory impact without having an adverse 
impact on Industry Members. The requirement to report rejected order 
messages applies to Participants, not Industry Members, and, therefore, 
does not directly affect the reporting and other requirements 
applicable to Industry Members. Accordingly, CAT LLC does not believe 
that the Rejected Message Amendment would have an adverse impact on 
Industry Members or their costs.
iv. The Rejected Message Amendment Would Enhance Market Efficiency
    CAT LLC also believes that the Rejected Message Amendment would 
enhance the efficiency of the securities markets because it would 
reduce costs with limited regulatory impact. As discussed above, the 
Rejected Message Amendment would provide significant annual cost 
savings for CAT LLC. It also would reduce costs of Participants 
required to report rejected messages. Such cost savings would not only 
benefit CAT LLC, but also would provide cost savings for any 
Participants and Industry Members that are required to fund the CAT in 
accordance with the CAT NMS Plan. Ultimately, such cost savings would 
benefit investors and the U.S. markets as a whole, thereby facilitating 
the goals of the Exchange Act.
6. Data Availability Amendment: Adopt More Cost-Effective Data 
Availability Timeline
    CAT LLC proposes to amend the CAT NMS Plan to adopt a more cost-
effective data availability timeline (the ``Data Availability 
Amendment''). The Data Availability Amendment would (1) extend the time 
by which raw unprocessed data must be made available to Participants' 
regulatory staff and SEC from 12:00 p.m. Eastern Time on T+1 to 8:00 
a.m. Eastern Time on T+2, and (2) extend the time by which final data 
must be ready for regulators from 8:00 a.m. Eastern Time on T+5 to 8:00 
a.m. Eastern Time on T+6. The Data Availability Amendment would reduce 
CAT costs for cloud hosting services by approximately $1.5-$2 million 
annually. Extending the timelines permits flexibility in the deployment 
of compute resources, permitting cost reduction through optimization.
    The 2025 Cost Savings Exemptive Order did not address the timeline 
changes included in the Data Availability Amendment. Accordingly, the 
estimated cost savings of approximately $1.5-$2 million annually are 
over and above the cost savings allowed via the 2025 Cost Savings 
Exemptive Order.
a. Current CAT NMS Plan Requirements
    Section 6.1 of Appendix D of the CAT NMS Plan (Data Processing) 
sets forth the following timeframes (also reflected in Figure A of 
Section 6.1) regarding data availability:
    <bullet> Noon Eastern Time T+1 (transaction date + one day)--
Initial data validation, lifecycle linkages and communication of errors 
to CAT Reporters;
    <bullet> 8:00 a.m. Eastern Time T+5 (transaction date + five 
days)--Corrected data available to Participant regulatory staff and the 
SEC.
    Section 6.2 of Appendix D of the CAT NMS Plan (Data Availability 
Requirements) provides that ``[p]rior to 12:00 p.m. Eastern Time on 
T+1, raw unprocessed data that has been ingested by the Plan Processor 
must be available to Participants' regulatory staff and the SEC,'' and 
that ``[b]etween 12:00 p.m. Eastern Time on T+1 and T+5, access to all 
iterations of processed data must be available to Participants' 
regulatory staff and the SEC.''
    Section 6.3 of Appendix D of the CAT NMS Plan (Exceptions to Data 
Availability Requirements) describes ``Raw Unprocessed Data'' to mean 
``data that has been ingested by the Plan Processor and made available 
to regulators prior to 12:00 p.m. Eastern Time on T+1,'' and describes 
``Interim Operational Data'' to mean ``all processed, validated and 
unlinked data made available to regulators by T+1 at 12:00 p.m. ET and 
all iterations of processed data made available to regulators between 
T+1 and T+5, but excludes the final version of corrected data that is 
made available at T+5 at 8:00 a.m. ET.''
b. Proposed Revisions to CAT NMS Plan
    CAT LLC proposes to revise references in Sections 6.1, 6.2 and 6.3 
of Appendix D of the CAT NMS Plan to reflect the proposed revised 
timeline.\110\
---------------------------------------------------------------------------

    \110\ CAT LLC has previously sought exemptive relief from the 
requirement to provide linkage feedback by T+1 at noon ET, and from 
the requirement that CAT Reporters resubmit corrected data to CAT by 
T+3 at 8 a.m. ET. See Letter from Michael Simon, CAT NMS Plan 
Operating Committee Chair, to Vanessa Countryman, Secretary,

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

    With regard to Section 6.1 of Appendix D of the CAT NMS Plan, CAT 
LLC proposes to revise the following bullet in Section 6.1 of Appendix 
D of the CAT NMS Plan: ``8:00 a.m. Eastern Time T+5 (transaction date + 
five days)--Corrected data available to Participant regulatory staff 
and the SEC,'' by replacing the reference to 8:00 a.m. Eastern Time T+5 
with 8:00 a.m. Eastern Time T+6. Moreover, CAT LLC proposes to make 
corresponding changes to the times in Figure A in Section 6.1 of 
Appendix D of the CAT NMS Plan.
---------------------------------------------------------------------------

    \111\ In connection with the Interim CAT-Order-ID Amendment 
discussed above, CAT LLC proposes to delete the phrase ``Life Cycle 
Linkage'' from the second box in Figure A in Section 6.1 of Appendix 
D of the CAT NMS Plan, which currently states: ``12:00 p.m. ET T+1 
Initial Validation, Life Cycle Linkage, Communication of Errors.''
    \112\ Assuming CAT Data is required to be made available on a 
daily basis, expanding the data availability timeline beyond T+2 
and/or T+6 would not result in additional material cost savings 
because the Plan Processor would still be required to process the 
same amount of data.
---------------------------------------------------------------------------

    CAT LLC also proposes the following changes to Section 6.2 of 
Appendix D:
    <bullet> CAT LLC proposes to replace the reference to 12:00 p.m. 
Eastern Time on T+1 with a reference to 8:00 a.m. Eastern Time on T+2 
in the following sentence in Section 6.2 of Appendix D of the CAT NMS 
Plan: ``Prior to 12:00 p.m. Eastern Time on T+1, raw unprocessed data 
that has been ingested by the Plan Processor must be available to 
Participants' regulatory staff and the SEC.''
    <bullet> CAT LLC proposes to replace the reference to 12:00 p.m. 
Eastern Time on T+1 with a reference to 8:00 a.m. Eastern Time on T+2, 
and the reference to T+5 with T+6 in the following sentence in Section 
6.2 of Appendix D of the CAT NMS Plan: ``Between 12:00 p.m. Eastern 
Time on T+1 and T+5, access to all iterations of processed data must be 
available to Participants' regulatory staff and the SEC.''
    <bullet> CAT LLC proposes to revise the third paragraph of Section 
6.2 of Appendix D of the CAT NMS Plan to change the reference to a 
five-day process to a ``six-day process,'' and to change the reference 
to T+5 to T+6.
    In addition, CAT LLC proposes to revise the timeline for providing 
raw unprocessed data to regulators by replacing the reference to 
``12:00 p.m. Eastern Time on T+1'' with the reference to ``8:00 a.m. 
Eastern Time on T+2.'' As a result, this statement would read as 
follows: ``Raw Unprocessed Data older than 15 days. `Raw Unprocessed 
Data' means data that has been ingested by the Plan Processor and made 
available to regulators prior to 8:00 a.m. Eastern Time on T+2.''
c. The Benefits of the Data Availability Amendment Significantly 
Outweigh Any Regulatory Impact
i. The Data Availability Amendment Would Result in an Estimated $1.5-$2 
Million in Annual Cost Savings for Cloud Hosting Services
    CAT LLC, after consultation with the Plan Processor, has determined 
that adopting the more cost-efficient data availability deadlines as 
set forth in this Data Availability Amendment would allow CAT LLC to 
achieve approximately $1.5-$2 million in annual cost savings in cloud 
hosting services. Extending the timelines permits flexibility in the 
deployment of compute resources, permitting cost reduction through 
optimization. These cost savings estimates are based on certain 
assumptions and the current scope of the CAT, and may vary based on, 
among other things, the details of the requirements in any final 
amendment approved by the Commission.\113\
---------------------------------------------------------------------------

    \113\ See supra notes 9 and 10.
---------------------------------------------------------------------------

    To implement the proposal, the Plan Processor has proposed a one-
time change request setting forth an implementation fee of 
approximately $200,000-$400,000. The Plan Processor estimates that it 
would take approximately three to six months to fully implement the 
changes for the Data Availability Amendment. One-time implementation 
costs will generally consist of Plan Processor labor costs associated 
with coding and software development, as well as any related cloud fees 
associated with the development, testing, and load testing of the 
proposed changes for the proposed amendment. Even accounting for this 
one-time implementation cost, the proposal would allow CAT LLC to 
achieve substantial cost savings in the first year.
ii. The Data Availability Amendment Would Preserve the Core Regulatory 
Purposes of the CAT
    The CAT is not a real-time system. As a result, CAT LLC believes 
that this Data Availability Amendment would have limited regulatory 
impact. The Participants unanimously agree that obtaining a final 
lifecycle by T+6, in lieu of T+5, is sufficient to conduct their 
regulatory programs, and that the cost savings associated with 
modifying the current processing timelines substantially outweigh any 
limited delay associated with this shift to T+6, particularly given 
that regulators will continue to have access to raw unprocessed data 
ingested by the Plan Processor prior to T+2 at 8:00 a.m. ET and will 
continue to have access to all processed data between T+2 at 8:00 a.m. 
ET and T+6 at 8:00 a.m. ET. Accordingly, CAT LLC has determined that 
the modified data availability timeline proposed herein would not 
adversely affect market oversight.
iii. The Data Availability Amendment Would Not Adversely Impact 
Industry Members
    CAT LLC also believes that the Data Availability Amendment would 
reduce costs with limited regulatory impact without having an adverse 
impact on Industry Members. Changing the timelines for providing data 
to the regulators would not directly affect the reporting and other 
requirements applicable to Industry Members. Accordingly, CAT LLC does 
not anticipate that the Data Availability Amendment would have an 
adverse impact on Industry Members' reporting or their costs.
iv. The Data Availability Amendment Would Enhance Market Efficiency
    CAT LLC also believes that this Data Availability Amendment would 
enhance the efficiency of the securities markets. For many years, CAT 
LLC has received extensive feedback from the Plan Processor regarding 
various technical and operational issues

[[Page 61526]]

associated with satisfying current Plan processing deadlines. In 
particular, the Plan Processor has long highlighted the inherent 
complexity and substantial cost of processing extremely large volumes 
of data in a short period of time. By extending the timelines for 
providing regulators with data by mere hours, the Plan Processor would 
have additional time to process the data in a more cost-efficient 
manner.
    In addition, as discussed above, the Data Availability Amendment 
would provide significant annual cost savings for CAT LLC. Such cost 
savings would not only benefit CAT LLC, but it would also provide cost 
savings for any Participants and Industry Members that are required to 
fund the CAT in accordance with the CAT NMS Plan. Ultimately, such cost 
savings would benefit investors and the U.S. markets as a whole, 
thereby facilitating the goals of the Exchange Act.
7. Reference Data Amendment: Elimination of CAIS and Reporting of 
Customer and Account Information/Adoption of Reference Data Approach To 
Generate CCIDs
    CAT LLC proposes to amend the CAT NMS Plan to eliminate both the 
requirement to report Customer Account Information and Customer 
Identifying Information to the CAT and to eliminate CAIS from the CAT, 
and to adopt a new more, focused approach for the CCID that would allow 
for the generation of a CCID while minimizing the data needed for its 
creation. This ``Reference Data Amendment'' would reduce CAT costs for 
cloud hosting services by approximately $4-$6 million annually, as well 
as provide for potential reductions in the operating fees for the Plan 
Processor.\114\ As discussed in more detail in subsection 9.a below, in 
direct response to industry feedback, CAT LLC determined to propose 
this Reference Data Amendment instead of the Full Elimination of the 
CAIS/CCID Component of the Original CAT LLC Proposal, despite the lower 
cost savings associated with the Reference Data Amendment.
---------------------------------------------------------------------------

    \114\ As noted above, the potential cost savings related to the 
operating fees for the Plan Processor with regard to the 2025 Cost 
Savings Amendment are $7 million. The November 2025 budget includes 
approximately $24.5 million in CAIS-related Plan Processor fees, 
including a $20.7 million in CAIS operating fee and a $3.8 million 
license fee.
---------------------------------------------------------------------------

    The 2025 Cost Savings Exemptive Order did not address the proposed 
changes to CAIS. Accordingly, the estimated cost savings related to the 
elimination of CAIS and its replacement by the Reference Data Amendment 
are separate and apart from the cost savings described in the 2025 Cost 
Savings Exemptive Order.
    As previously noted, the current 2025 CAT budget of $188 million 
includes an estimated $122 million in cloud hosting services and $54 
million in total Plan Processor fees.\115\ Under the Reference Data 
Amendment, the current CAIS-related cloud hosting services fees, 
estimated at $6.5 to $9 million, would be reduced by approximately $4 
to $6 million annually, resulting in an estimated $2.5 to $3 million in 
cloud hosting fees on an annualized basis. The current CAIS-related 
Plan Processor fees, estimated at $24.5 million ($20.7 million in 
operating fees and $3.8 million in licensing fees), would also be 
eliminated, but would be offset in part by other estimated increases in 
Plan Processor fees, resulting in total Plan Processor fees of 
approximately $47 million on an annualized basis (inclusive of 
approximately $4 million in licensing fees). Thus, overall, the Plan 
Processor has estimated a $7 million reduction ($54 million reduced to 
$47 million) in total Plan Processor fees under the proposed 2025 Cost 
Savings Amendment. Accordingly, the difference in total Plan Processor 
fees between the Original CAT LLC Proposal ($39 million) and this 2025 
Cost Savings Amendment ($47 million) is approximately $8 million, which 
includes approximately $4 million in licensing fees.
---------------------------------------------------------------------------

    \115\ See supra, note 11.
---------------------------------------------------------------------------

a. Customer Information Approach
    The CAT NMS Plan originally adopted the Customer Information 
Approach, which is ``a reporting model that requires broker-dealers to 
provide detailed account and Customer information to the Central 
Repository, including the specific identities of all Customers 
associated with each account, and have the Central Repository correlate 
the Customer information across broker-dealers, assign a unique 
customer identifier to each Customer (i.e., the CAT-Customer-ID), and 
use that unique customer identifier consistently across all CAT Data.'' 
\116\
---------------------------------------------------------------------------

    \116\ Section A.1(a)(iii) of Appendix C of the CAT NMS Plan.
---------------------------------------------------------------------------

    The Customer Information Approach requires each Industry Member to 
assign a unique Firm Designated ID or FDID \117\ to each customer 
account. Under the Customer Information Approach in the original CAT 
NMS Plan, an FDID is a unique and persistent identifier for each 
trading account designated by Industry Members for purposes of 
providing data to the Central Repository.\118\ According to the CAT NMS 
Plan, Industry Members must submit an initial set of Customer 
information to the Central Repository, including, as applicable, (1) 
the FDID; (2) the Customer's name, address, date of birth, Individual 
Taxpayer Identification Number (``ITIN'')/Social Security Number 
(``SSN''), and individual's role in the account (e.g., primary holder, 
joint holder, guardian, trustee, person with power of attorney); and 
(3) Legal Entity Identifier (``LEI''), and/or Large Trader ID 
(``LTID''), if applicable, which would be updated as set forth in the 
CAT NMS Plan.\119\
---------------------------------------------------------------------------

    \117\ The term ``Firm Designated ID'' is defined in the CAT NMS 
Plan as: ``(1) a unique and persistent identifier for each trading 
account designated by Industry Members for purposes of providing 
data to the Central Repository provided, however, such identifier 
may not be the account number for such trading account if the 
trading account is not a proprietary account; (2) a unique and 
persistent relationship identifier when an Industry Member does not 
have an account number available to its order handling and/or 
execution system at the time of order receipt, provided, however, 
such identifier must be masked; or (3) a unique and persistent 
entity identifier when an employee of an Industry Member is 
exercising discretion over multiple client accounts and creates an 
aggregated order for which a trading account number of the Industry 
Member is not available at the time of order origination, where each 
such identifier is unique among all identifiers from any given 
Industry Member.'' Section 1.1 of the CAT NMS Plan.
    \118\ Section 1.1 of the CAT NMS Plan.
    \119\ Section A.1(a)(iii) of Appendix C of the CAT NMS Plan.
---------------------------------------------------------------------------

    Under the CAT NMS Plan, for each new order submitted to the 
transaction database of the CAT Central Repository, broker-dealers are 
required to report the FDID for such new order, and the Plan Processor 
must associate specific Customers and their CAT-Customer-IDs with 
individual order events based on the reported FDIDs. Within the Central 
Repository, each Customer would be uniquely identified by identifiers 
or a combination of identifiers such as an ITIN/SSN, date of birth, 
and, as applicable, LEI and LTID. The Plan Processor is required to use 
these unique identifiers to map orders to specific Customers across all 
broker-dealers.\120\

    Under the Customer Information Approach, the Plan Processor must 
maintain information of sufficient detail to uniquely and consistently 
identify each Customer across all CAT Reporters, and associated 
accounts from each CAT Reporter, and must document and publish, with 
the approval of the Operating Committee, the minimum list of attributes 
to be captured to maintain this association.\121\ In addition, the Plan 
Processor must maintain valid Customer

Identifying Information and Customer Account Information for each 
trading day and provide a method for Participants and the Commission to 
easily obtain historical changes to that information (e.g., name 
changes, address changes).\122\
---------------------------------------------------------------------------

    \121\ Section 9.1 of Appendix D of the CAT NMS Plan.
    \122\ Section A.1(a)(iii) of Appendix C of the CAT NMS Plan.
---------------------------------------------------------------------------

    Customer Identifying Information is defined in Section 1.1 of the 
CAT NMS Plan to mean:

information of sufficient detail to identify a Customer, including, 
but not limited to, (a) with respect to individuals: name, address, 
date of birth, individual tax payer identification number 
(``ITIN'')/social security number (``SSN''), individual's role in 
the account (e.g., primary holder, joint holder, guardian, trustee, 
person with the power of attorney); and (b) with respect to legal 
entities: name, address, Employer Identification Number (``EIN'')/
Legal Entity Identifier (``LEI'') or other comparable common entity 
identifier, if applicable; provided, however, that an Industry 
Member that has an LEI for a Customer must submit the Customer's LEI 
in addition to other information of sufficient detail to identify a 
Customer.

    Customer Account Information is defined in Section 1.1 of the CAT 
NMS Plan to include, but not be limited to:

account type, customer type, date account opened, and large trader 
identifier (if applicable); except, however, that (a) in those 
circumstances in which an Industry Member has established a trading 
relationship with an institution but has not established an account 
with that institution, the Industry Member will (i) provide the 
Account Effective Date in lieu of the ``date account opened''; (ii) 
provide the relationship identifier in lieu of the ``account 
number''; and (iii) identify the ``account type'' as a 
``relationship''; (b) in those circumstances in which the relevant 
account was established prior to the implementation date of the CAT 
NMS Plan applicable to the relevant CAT Reporter (as set forth in 
Rule 613(a)(3)(v) and (vi)), and no ``date account opened'' is 
available for the account, the Industry Member will provide the 
Account Effective Date in the following circumstances: (i) where an 
Industry Member changes back office providers or clearing firms and 
the date account opened is changed to the date the account was 
opened on the new back office/clearing firm system; (ii) where an 
Industry Member acquires another Industry Member and the date 
account opened is changed to the date the account was opened on the 
post-merger back office/clearing firm system; (iii) where there are 
multiple dates associated with an account in an Industry Member's 
system, and the parameters of each date are determined by the 
individual Industry Member; and (iv) where the relevant account is 
an Industry Member proprietary account.\123\

b. CCID Alternative
    On March 17, 2020, the Commission granted exemptive relief related 
to the reporting of SSNs/ITINs, dates of birth, and account numbers to 
the CAT (``2020 CCID Alternative Exemptive Order'').\124\ Instead of 
reporting dates of birth and account numbers, Industry Members are 
required to report years of birth and FDIDs. In addition, the 2020 CCID 
Alternative Exemptive Order also permitted the implementation of the 
CCID Alternative. Under the CCID Alternative, the Plan Processor 
generates a unique identifier for a Customer, called a CCID, using a 
two-phase transformation process that avoids the requirement to have 
SSNs/ITINs reported to the CAT as originally contemplated by SEC Rule 
613 and the CAT NMS Plan. In the first transformation phase, a CAT 
Reporter transforms the SSN/ITIN into an interim transformed value. 
This transformed value, and not the SSN/ITIN, is submitted to a 
separate system within the CAT, referred to as the CCID Subsystem. The 
transformed value is sent to the CAT separate and apart from the other 
Customer and account information. The CCID Subsystem then performs a 
second transformation to create a globally unique CCID for each 
Customer that is not known to, and not shared with, the original CAT 
Reporter. The CCID is then sent to CAIS, where it is linked with the 
other Customer and account information. The CCID may then be used by 
the Participants' regulatory staff and the SEC in queries and analyses 
of CAT Data. CAT LLC currently operates in accordance with the CCID 
Alternative.

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

c. 2025 CAIS Exemptive Order
    On February 10, 2025, the Commission published an order (the ``2025 
CAIS Exemptive Order'') sua sponte, granting exemptive relief related 
to the reporting of names, addresses, and years of birth for natural 
persons reported with transformed SSNs or ITINs to CAIS.\125\ Upon 
review of this order, CAT LLC noted certain limitations.
---------------------------------------------------------------------------

    \125\ Exchange Act Release No. 102386 (Feb. 10, 2025), 90 FR 
9642 (Feb. 14, 2025) (``2025 CAIS Exemptive Order'').
---------------------------------------------------------------------------

    First, CAT LLC and the Participants understand that the 2025 CAIS 
Exemptive Order is permissive at the discretion of Industry Members 
(meaning that Industry Members may choose to take advantage of the 
exemptive relief or choose to continue reporting names, addresses, and 
years of birth for natural persons reported with transformed SSNs or 
ITINs to CAIS) and only applies to natural persons reported with 
transformed SSNs or ITINs, and not to natural persons reported without 
transformed SSNs/ITINs, including foreign nationals, or to legal 
entities. As a result, the Plan Processor must maintain all software 
that is required to continue to accept such Customer information for 
those Industry Members who choose to continue reporting it, as well as 
to support regulatory queries of names, addresses, and years of birth 
for non-exempted persons. Consequently, the 2025 CAIS Exemptive Order 
will not result in any cost savings.
    Second, in granting its 2025 CAIS Exemptive Order, the SEC cited 
security considerations, concluding that the benefits of reporting 
names, addresses, and years of birth for natural persons reported with 
transformed SSNs or ITINs no longer justify the potential risks.\126\ 
However, the 2025 CAIS Exemptive Order only applies to the reporting of 
such Customer information after the date of the order, and only to the 
extent that Industry Members choose to discontinue reporting such 
exempted Customer information. In addition, the 2025 CAIS Exemptive 
Order does not address the deletion of existing, previously reported 
Customer information currently stored in CAIS. Further, the 2025 CAIS 
Exemptive Order does not apply to natural persons who are not reported 
with transformed SSNs or ITINs (e.g., foreign nationals) or legal 
entities.
---------------------------------------------------------------------------

    \126\ See 2025 CAIS Exemptive Order at 9643-44.
---------------------------------------------------------------------------

    In light of these issues, on March 7, 2025, CAT LLC filed with the 
SEC a proposed amendment to the CAT NMS Plan relating to the CAIS.\127\ 
This proposed amendment would eliminate requirements that Industry 
Members report Customer names, Customer addresses, account names, 
account addresses, years of birth, and authorized trader names, would 
provide for the deletion of previously reported Customer information, 
and would achieve significant annual savings in CAT operating costs. 
The SEC has not yet approved or disapproved this proposed amendment.

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

d. Description of Reference Data Approach
    With this Reference Data Amendment, CAT LLC proposes to amend the 
CAT NMS Plan to adopt the Reference Data

[[Page 61528]]

Approach. The following describes the Reference Data Approach.
i. Submission of Data to CAT by Industry Members
    Under the Reference Data Approach, Industry Members would be 
required to report to the CAT a smaller subset of the data than they 
are currently required to report to the CAT. The following describes 
the data that Industry Members would be required to submit to the CAT 
under the Reference Data Approach.
    Industry Members would be required to collect and record certain 
identification information for their Customers (such as SSNs, ITINs, 
Employer Identification Numbers (``EINs'') or foreign identifiers). 
However, Industry Members would not provide such Customer 
identification information to the CAT. Instead, for each Customer other 
than foreign Customers, each Industry Member would submit to the 
Reference Database of the CAT (the information system of the CAT that 
would contain Reference Data) (1) the hashed version of each Customer's 
identification information, which would be referred to as the 
Transformed Identifier or TID, as well as (2) the type of identifier 
used to create the Transformed Identifier (e.g., SSN/ITIN, EIN or 
foreign identifier), and such type of identifier would be referred to 
as the Transformed Identifier Type or TID Type. For foreign Customers, 
each Industry Member would be required to submit two items in addition 
to the TID and TID Type; Industry Members also would be required to 
submit (1) the Foreign TID Type, which is the type of foreign 
identifier used to create the TID (e.g., passport, LEI, driver's 
license), and (2) the Foreign TID Country Code, which is the country 
that issued the foreign identifier used to create the TID. This data is 
collectively referred to as ``CCID Generation Data.''
    In addition, Industry Members would be required to submit to the 
Reference Database the following ``CCID Transaction Enrichment Data'' 
for each account and Customer, as applicable:
    <bullet> Firm Designated ID;
    <bullet> Date FDID Opened, which means the date the account was 
opened (or the Account Effective Date);
    <bullet> Date FDID Closed, which means the date the account was 
closed (or relationship or entity identifier was ended) at the Industry 
Member;
    <bullet> Customer Role Start Date, which means the date the 
Customer became associated with the account; and
    <bullet> Customer Role End Date, which means the date the Customer 
is no longer associated with the account.
    Furthermore, Industry Members would be required to report to the 
Reference Database the following data types: account type, clearing 
broker, branch office, registered representative, and individual's role 
in the account. Industry Members would be required to report this data 
to the Reference Database, not to CAIS. This data, along with CCID 
Generation Data and CCID Transaction Enrichment Data would be referred 
to as Reference Data. These five categories of data would assist 
regulatory surveillance programs and would help to reduce Electronic 
Blue Sheet requests and other inquiries from the Participants and the 
SEC. CAT LLC requests comment on the inclusion of these five categories 
of data as Reference Data.
    In addition, the definition of Reference Data would not include the 
Large Trader ID (``LTID'').\128\ Accordingly, CAT LLC also requests 
comment on the exclusion of the LTID from the Reference Database.
---------------------------------------------------------------------------

    \128\ For a discussion of LTIDs and the large trader 
requirements under Rule 13h-1 under the Exchange Act with regard to 
the CAT NMS Plan, see CAT NMS Plan Approval Order at 84777-8.
---------------------------------------------------------------------------

ii. Reference Database
    Under the Reference Data Approach, Industry Members would no longer 
report Customer Account Information and Customer Identifying 
Information to CAIS, and CAIS would be eliminated. Instead, the 
Reference Data, which includes CCID Generation Data, CCID Transaction 
Enrichment Data, and account type, clearing broker, branch office, 
registered representative, and individual's role in the account, would 
be reported to and collected in the Reference Database. 
Correspondingly, the regulatory and other features related to CAIS and 
the collection of Customer information (e.g., Regulatory Portal, CAIS 
Report Card, CCID Rotation) also would eliminated.
iii. Generation of CCID
    The process for generating the CCID under the Reference Data 
Approach is materially the same as the current process. Using a 
combination of the TID and the TID Type (or, for foreign Customers, a 
combination of TID, TID Type, Foreign TID Type and Foreign TID Country 
Code), the Plan Processor would create a CCID for each Customer. The 
CCID is a globally unique identifier generated for each combination of 
TID and TID Type (or, for foreign Customers, a combination of TID, TID 
Type, Foreign TID Type and Foreign TID Country Code). Each time any 
Industry Member submits the same combination of these two field values 
(or these four field values for foreign customers), the same CCID would 
be generated within the CAT such that each unique Customer would only 
be assigned a single CCID.
iv. Enrichment of Reportable Events With CCID
    The Plan Processor would enrich Reportable Events for an order with 
the CCID for the relevant Customer using the FDID as the key. The 
output of this enrichment process would be a mapping of CCIDs to FDIDs 
that would allow regulators to associate a Customer with transaction 
data. The Plan Processor would use the CCID Transaction Enrichment Data 
reported by Industry Members to the Reference Database (i.e., FDID, 
Date FDID Opened, Date FDID Closed, Customer Role Start Date and 
Customer Role End Date) to enrich Reportable Events with the CCID. The 
Date FDID Opened and Date FDID Closed are necessary to determine which 
Reportable Events are eligible for enrichment with the appropriate 
CCID, and the Customer Role Start Date and Customer Role End Date are 
necessary to determine which CCIDs were associated with the FDID on the 
date of the Reportable Event. Once the Plan Processor enriches 
Reportable Events with the CCID, regulators can track the same CCID and 
Customer across different FDIDs and across different Industry Members.
v. Regulatory Access to Reference Data
    The Plan Processor will continue to create a CCID:FDID mapping 
table, which allows regulators to connect accounts with customers. 
However, under the Reference Data Approach, the mapping table will be 
expanded to include the additional Reference Data elements. In 
addition, relevant historical CCID, FDID and Reference Data will be 
migrated to the updated mapping table; with such migration, such 
relevant historical data would not be eliminated.
    With the elimination of CAIS, the CAIS regulatory portal also would 
be eliminated. With the Reference Data Approach, regulators would 
access the FDID, CCID and Reference Data via the FDID:CCID mapping 
table. The mapping table with the FDID, CCID and Reference Data would 
be made available to regulators via the CAT query tools (i.e., the user 
defined direct query and bulk extraction tools), or a regulator's own 
regulatory applications for the CAT. In addition, to the extent that a 
regulator needs to use a social security number, EIN, or foreign 
identifier (which it has obtained from outside the CAT) to investigate 
CAT activity, the Plan Processor would provide a method (e.g., an 
application programming

[[Page 61529]]

interface (``API'')) that would permit regulators to use the social 
security number to look up a CCID.
e. Proposed Revisions to the CAT NMS Plan
    To incorporate the Reference Data Approach in the CAT NMS Plan, CAT 
LLC proposes the following revisions to CAT NMS Plan.
i. Definitions
    CAT LLC proposes adding certain new defined terms to Section 1.1 of 
the CAT NMS Plan, and deleting terms that would be obsolete with the 
adoption of the Reference Data Approach. Specifically, CAT LLC would 
add the following new defined terms and their definitions:
    <bullet> ``CCID Transaction Enrichment Data'' shall mean Firm 
Designated ID, Date FDID Opened, Date FDID Closed, Customer Role Start 
Date, and Customer Role End Date.
    <bullet> ``CCID Generation Data'' shall mean the Transformed 
Identifier and Transformed Identifier Type.
    <bullet> ``Customer Role Start Date'' means the date the Customer 
became associated with the relevant account for the order.
    <bullet> ``Customer Role End Date'' means the date the Customer is 
no longer associated with the relevant account for the order.
    <bullet> ``Date FDID Closed'' means the date the relevant account 
for the order was closed (or relationship or entity identifier was 
ended) at the Industry Member.
    <bullet> ``Date FDID Opened'' means the date the relevant account 
for the order was opened; except, however, that (a) in those 
circumstances in which an Industry Member has established a trading 
relationship with an institution but has not established an account 
with that institution, the Industry Member will provide the Account 
Effective Date in lieu of the ``Date FDID Opened;'' and (b) in those 
circumstances in which the relevant account was established prior to 
the implementation date of the CAT NMS Plan applicable to the relevant 
CAT Reporter (as set forth in Rule 613(a)(3)(v) and (vi)), and no 
``date account opened'' is available for the account, the Industry 
Member will provide the Account Effective Date in the following 
circumstances: (i) where an Industry Member changes back office 
providers or clearing firms and the date account opened is changed to 
the date the account was opened on the new back office/clearing firm 
system; (ii) where an Industry Member acquires another Industry Member 
and the date account opened is changed to the date the account was 
opened on the post-merger back office/clearing firm system; (iii) where 
there are multiple dates associated with an account in an Industry 
Member's system, and the parameters of each date are determined by the 
individual Industry Member; and (iv) where the relevant account is an 
Industry Member proprietary account.\129\
---------------------------------------------------------------------------

    \129\ Note that the language in paragraphs (a) and (b) of the 
proposed definition of ``Date FDID Opened'' track the language in 
the current definition of ``Customer Account Information.'' Section 
1.1 of the CAT NMS Plan.
---------------------------------------------------------------------------

    <bullet> ``Foreign TID Country Code'' means the country that issued 
the foreign identifier used to create the Transformed Identifier.
    <bullet> ``Foreign TID Type'' means, for foreign customers, the 
type of foreign identifier used to create the Transformed Identifier 
(e.g., passport, Legal Entity Identifier (``LEI''), or driver's 
license).
    <bullet> ``Reference Data'' means CCID Generation Data, CCID 
Transaction Enrichment Data, account type, clearing broker, branch 
office, registered representative, and individual's role in the 
account.
    <bullet> ``Reference Database'' means the information system of the 
CAT containing Reference Data.
    <bullet> ``Transformed Identifier Type'' or ``TID Type'' means the 
type of identifier used to create the Transformed Identifier (e.g., 
SSN/ITIN, EIN or foreign identifier).
    <bullet> ``Transformed Identifier'' or ``TID'' means the 
transformed version of the input used to identify unique Customers, 
where such inputs may include, but are not limited to, individual tax 
payer identification number (``ITIN'') or social security number 
(``SSN''), Employer Identification Number (EIN, including QI-EIN, WP-
EIN, and WT-EIN), or certain foreign identifiers.
    CAT LLC would also add the phrase ``or `CAT-Customer-ID' or `CCID' 
'' to the current definition of ``Customer-ID.'' The revised definition 
would read as follows `` `Customer-ID' or `CAT-Customer-ID' or `CCID' 
has the same meaning provided in SEC Rule 613(j)(5).''
    Finally, CAT LLC proposes to eliminate the terms ``Customer Account 
Information'' and ``Customer Identifying Information'' and ``PII'' 
\130\ as they would no longer be relevant under the Reference Data 
Approach.\131\ However, as noted above, with the Reference Data 
Approach, Industry Members would be required to report ``account type'' 
to the Reference Database; ``account type'' is currently included in 
the definition of ``Customer Account Information.'' Similarly, Industry 
Members would be required to report ``the individual's role in the 
account''; this item is currently included in the definition of 
``Customer Identifying Information.''
---------------------------------------------------------------------------

    \130\ CAT LLC proposes to eliminate the references to and 
discussion of PII in Sections 6.2(b)(v)(F) and 6.10(c)(ii) of the 
CAT NMS Plan, as well as Section 4.1, 4.1.2, 4.1.4, 4.1.6 (in its 
entirety), 6.2, 8.1.3, 8.2 and 8.2.2 of Appendix D of the CAT NMS 
Plan. CAT LLC also proposes to delete the reference to ``Customer 
Account Information and Customer Identifying Information'' from 
Section 6.2(a)(v)(C) of the CAT NMS Plan, which addresses 
obligations of the Chief Compliance Officer.
    \131\ CAT LLC also proposes to note in Section 1.1 of the CAT 
NMS Plan that the terms ``Customer Account Information'' and 
``Customer Identifying Information'' as used in the Financial 
Accountability Milestones (Initial Industry Member Core Equity 
Reporting; Full Implementation of Core Equity Reporting; Full 
Availability and Regulatory Utilization of Transactional Database 
Functionality; and Full Implementation of CAT NMS Plan Requirements) 
are no longer defined terms.
---------------------------------------------------------------------------

ii. Section 6.4 of the CAT NMS Plan
    CAT LLC proposes to revise Section 6.4 of the CAT NMS Plan to 
reflect the Reference Data Approach. Section 6.4(d)(ii)(C) of the CAT 
NMS Plan requires each Participant, via its CAT Compliance Rule, to 
require its Industry Members to record and report to the Central 
Repository the following: ``for the original receipt or origination of 
an order, the Firm Designated ID for the relevant Customer, and in 
accordance with Section 6.4(d)(iv), Customer Account Information and 
Customer Identifying Information for the relevant Customer.'' CAT LLC 
proposes to revise this provision to indicate that, under the Reference 
Data Approach, Industry Members are required to provide the CCID 
Transaction Enrichment Data for the relevant account for the order and 
the CCID Generation Data for the relevant Customer for the order, not 
the Customer Account Information or Customer Identifying Information. 
Accordingly, CAT LLC proposes to revise Section 6.4(d)(ii)(C) of the 
CAT NMS Plan to require Industry Members to provide the following: 
``with respect to the original receipt or origination of an order, the 
CCID Transaction Enrichment Data for the relevant account for the 
order, and the CCID Generation Data for the relevant Customer for the 
order, in accordance with Section 6.4(d)(iv).''
    In addition, CAT LLC proposes to revise Section 6.4(d)(iv) of the 
CAT NMS Plan to reflect the Reference Data Approach as well. Section 
6.4(d)(iv) of the CAT NMS Plan currently states the following:

    Each Industry Member must submit an initial set of the Customer 
information

[[Page 61530]]

required in Section 6.4(d)(ii)(C) for Active Accounts to the Central 
Repository upon the Industry Member's commencement of reporting to 
the Central Repository. Each Industry Member must submit to the 
Central Repository any updates, additions or other changes to the 
Customer information required in Section 6.4(d)(ii)(C) on a daily 
basis for all Active Accounts. In addition, on a periodic basis as 
designated by the Plan Processor and approved by the Operating 
Committee, each Industry Member will be required to submit to the 
Central Repository a complete set of all Customer information 
required in Section 6.4(d)(ii)(C). The Plan Processor will correlate 
such Customer information across all Industry Members, use it to 
assign a Customer-ID for each Customer, and use the Customer-ID to 
link all Reportable Events associated with an order for a Customer.

    CAT LLC proposes to replace the references to Customer information 
with ``Reference Data,'' which includes CCID Generation Data, CCID 
Transaction Enrichment Data and additional data elements, in the first 
two sentences. As a result, Industry Members would be required to 
submit Reference Data for each Customer with an Active Account, not 
Customer information or Active Accounts, to the CAT.
    In addition, CAT LLC proposes to eliminate the periodic refresh of 
data, and therefore proposes to delete the following sentence from 
Section 6.4(d)(iv) of the CAT NMS Plan: ``In addition, on a periodic 
basis as designated by the Plan Processor and approved by the Operating 
Committee, each Industry Member will be required to submit to the 
Central Repository a complete set of all Customer information required 
in Section 6.4(d)(ii)(C).'' \132\ The periodic refresh requirement has 
been used with the existing approach to Customer information to provide 
a means to update Customer information that may change (e.g., name 
changes due to marriage, address changes due to moves). With the 
Reference Data Amendment, CAT reporting of this type of Customer 
information would no longer be required. Furthermore, Reportable Events 
would be submitted with an FDID, which would continue to be subject to 
validations by the Plan Processor.
---------------------------------------------------------------------------

    \132\ Note that the deletion of the periodic refresh requirement 
is not intended to change the current practice that allows Industry 
Members to report full account lists, rather than just the changes 
to such account lists, on a daily basis. See, e.g., CAT FAQ 16, 
<a href="https://www.catnmsplan.com/faq">https://www.catnmsplan.com/faq</a>.
---------------------------------------------------------------------------

    Finally, CAT LLC proposes to revise the last sentence of Section 
6.4(d)(iv) of the CAT NMS Plan to reflect the Reference Data Approach. 
It would state that ``[t]he Plan Processor will use the CCID Generation 
Data to assign a Customer-ID for each Customer, and use the CCID 
Transaction Enrichment Data to enrich and link all Reportable Events 
associated with an order with the CCID for a Customer.''
    With these changes, Section 6.4(d)(iv) of the CAT NMS Plan would 
read as follows:

    Each Industry Member must submit an initial set of the Reference 
Data required in Section 6.4(d)(ii)(C) for each Customer with an 
Active Account(s) to the Central Repository upon the Industry 
Member's commencement of reporting to the Central Repository. Each 
Industry M
