Self-Regulatory Organizations; CME Securities Clearing Inc.; 
Notice of Filing of Proposed Rule Change To Support Members' Risk 
Management of and Enhance Their Ability To Authorize Persons as Users

June 3, 2026.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(the ``Act'') \1\ and Rule 19b-4 thereunder,\2\ notice is hereby given 
that on May 21, 2026, CME Securities Clearing Inc. (``CMESC'') filed 
with the Securities and Exchange Commission (``SEC'' or ``Commission'') 
the proposed rule change described in Items I, II, and III below, which 
Items have been primarily prepared by CMESC. CMESC filed the proposed 
rule change pursuant to Section 19(b)(2) of the Act.\3\ The Commission 
is publishing this notice to solicit comments on the proposed rule 
change from interested persons.

I. CMESC's Statement of the Terms and Substance of the Proposed Rule 
Change

    The proposed rule change of CME Securities Clearing Inc. 
(``CMESC'') is in an Exhibit 5 and consists of modifications to the 
CMESC Rulebook (the ``Rules'') \4\ to (i) support Members' risk 
management of and enhance their ability to authorize persons as Users, 
by providing Members the means to enforce contractual termination 
rights against their authorized Users under their contractual 
arrangements with their authorized Users; (ii) create legal structures 
to provide security entitlement to an authorizing Member in each 
Supported User Account

[[Page 34667]]

associated with such Member's authorization and to grant secondary 
security interests in and liens against Independent User funds held by 
CMESC while affirming CMESC's first priority and unencumbered lien and 
security interest in such User funds; and (iii) strengthen and clarify 
Members' ability to participate in the close-out (liquidation) of 
positions of Users they authorize in the event of the User's Default. 
The proposed rule change includes proposed new Rule 316 (Member 
Exercise of Contractual Rights Against an Authorized User) and new Rule 
317 (Member Second Priority Lien Against Independent User Margin) and 
modifications to Rule 101 (Definitions), Rule 405 (Default Management 
Process), Rule 513 (Margin Deposited for Supported Users Using the Repo 
or Cash Treasury Clearing Services), Rule 602 (Submission of 
Transaction Data), and Rule 1507 (Default Management). Each 
modification is described in more detail below. These modifications 
will support Members' risk management of their authorized Users and are 
designed to support Members' ability and capacity to authorize Users. 
This, in turn, will support CMESC's efforts to attract and to on-board 
Members and Users prior to CMESC's launch of its Clearing Services and 
on an ongoing basis thereafter by enhancing the attractiveness of 
CMESC's Clearing Services offering for prospective Members, thereby 
promoting the prompt and accurate clearance and settlement of 
transactions in or involving U.S. Treasury securities. The proposed 
revisions to the CMESC Rules are in an Exhibit 5.

II. CMESC's Statement of the Purpose of, and Statutory Basis for the 
Proposed Rule Change

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

A. CMESC's Statement of the Purpose of, and Statutory Basis for the 
Proposed Rule Change

2. Purpose
Background
    On December 1, 2025, the Securities and Exchange Commission 
(``Commission'' or ``SEC'') issued an order approving CMESC's Form CA-1 
(``Application'') for registration as a clearing agency to provide 
central counterparty services for transactions involving U.S. Treasury 
securities, finding the Application satisfies the requirements of the 
Securities Exchange Act of 1934, as amended (``Act'') and rules and 
regulations thereunder.\5\ Based on engagement with market participants 
and trade associations during the Commission's review of the 
Application, CMESC has identified enhancements to its Rules designed to 
enhance Members' risk management flexibility and mitigate potential 
constraints on their ability to authorize Users due to potential 
capital constraints. More specifically, the proposed rule change is 
designed to further support prompt close-out of a User's positions, 
whether the User is subject to a termination event under binding 
contractual terms between it and its authorizing Member or the User is 
in Default to CMESC under the Rules.

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

1. Member Risk Management Considerations
    As provided in the Rules, a person may become a Participant to 
utilize CMESC's Clearing Services as a Member or a User.\6\ Members may 
clear proprietary Eligible Securities Transactions through CMESC \7\ 
and may authorize Users to clear their own proprietary Eligible 
Securities Transactions through CMESC.\8\ A person may become a User 
only with the authorization of a Member but is contractually bound to 
settle its Eligible Securities Transactions directly with CMESC.\9\ 
Users may participate in CMESC's Clearing Services as Independent Users 
or Supported Users.\10\ An Independent User is obligated to post margin 
and make Outstanding Exposure Settlement payments to CMESC for its 
Independent User Account.\11\ In contrast, for a Supported User, the 
Member authorizing the Supported User is obligated to post margin and 
make Outstanding Exposure Settlement payments to CMESC for the 
Supported User Account associated with the Member's authorization.\12\
---------------------------------------------------------------------------

    \6\ See e.g., Rule 301.
    \7\ Id.
    \8\ See e.g., 302(a) and 305(c).
    \9\ See e.g., Rules 305(d) and 1504(b).
    \10\ See e.g., Rule 301(b).
    \11\ See e.g., Rules 501 (margin) and 506 (Outstanding Exposure 
Settlement).
    \12\ See e.g., Rules 501 and 513 (margin) and 506 (Outstanding 
Exposure Settlement).
---------------------------------------------------------------------------

    A Member has certain obligations under the Rules with respect to 
persons admitted as Users pursuant to the Member's authorization. An 
authorizing Member must establish, maintain, and enforce User Due 
Diligence Policies and Procedures that demonstrate the Member's ability 
to, among other things, determine the risk profile of each User it 
authorizes and monitor the risks associated with clearing Eligible 
Securities Transactions by its authorized Users through CMESC.\13\ In 
the event of a User Default, if any losses remain after CMESC applies 
the margin posted to the Account of the Defaulting User associated with 
the Member's authorization as well as certain other assets available to 
CMESC as provided in the Rules,\14\ the authorizing Member will be 
required to provide funds to discharge such remaining losses pursuant 
to Rule 406(b)(iii) (User Default). If the Member fails to do so, CMESC 
may declare the Member in Default pursuant to Rule 406(b)(iii) and then 
apply the resources in the financial resources waterfall as provided 
for and in the priority specified in Rule 406(a) (Member Default), 
including such Defaulting Member's contribution to the Guaranty Fund.
---------------------------------------------------------------------------

    \13\ See Rule 306(c)(iii).
    \14\ When the Defaulting User is an Independent User, CMESC may 
also apply any other assets of the Independent User held by, pledged 
to, or otherwise available to the Corporation on behalf of that 
Independent User. See Rule 406(b)(ii)(A). When the Defaulting User 
is a Supported User, CMESC may also apply any collateral in excess 
of the margin requirement posted to it for the Supported User of the 
authorizing Member that such Member has not designated to CMESC as 
Funded Supported User Margin for any other Supported User Account or 
Supported User Margin for any other Supported User Account. See Rule 
406(b)(ii)(B).
---------------------------------------------------------------------------

    A Member must enter into an Authorization Agreement with each User 
it authorizes pursuant to which the Member agrees to authorize the 
User, as provided in Rule 305(c) (Member Authorization Agreement 
Between a Member and Authorized User). The Authorization Agreement is a 
commercial matter between the Member and authorized User, though its 
terms must be consistent with the Member's and User's respective rights 
and obligations to CMESC and to one another under the Rules. As 
provided in Rule 306(d) (Notice of Termination of User Authorization), 
a Member or User must provide CMESC with ten Business Days' advance 
notice of its termination of the Authorization Agreement for any 
reason, subject to CMESC's discretion to provide a shorter notification 
period. CMESC understands that Members want the certainty that its 
authorization of a given User will terminate immediately

[[Page 34668]]

upon notification to CMESC in certain circumstances, in order to 
further support such Members' ability to manage risk arising from its 
authorized Users' cleared activity.
2. Bank Regulatory Capital Considerations for Certain Members
    CMESC understands that for a bank or firm affiliated with a bank 
that becomes a Member, it is beneficial for the Member to have explicit 
means to enforce any contractual rights it may have under its 
agreement(s) governing its relationship with an authorized User to 
terminate all the authorized User's Eligible Securities Transactions 
cleared through CMESC in the User Account associated with the Member's 
authorization, so that such agreement(s) may be treated as qualified 
master netting agreements \15\ under bank regulatory capital 
requirements.\16\ CMESC further understands there may be regulatory 
capital benefits for a Member that is a bank or bank affiliate if such 
Member has a security interest, secondary to CMESC's, in the margin or 
other funds posted to the Account of an authorized User and to have 
assurance that in the event of an authorized User Default, the 
Defaulting User's open positions at CMESC will be closed out (i.e., 
liquidated or terminated) promptly.
---------------------------------------------------------------------------

    \15\ See 12 CFR 50.3 (definition of ``qualifying master netting 
agreement'').
    \16\ Pursuant to the relevant capital rules, we understand that 
a banking organization is only permitted to recognize the effects of 
financial collateral or offsetting transactions for capital purposes 
if the banking organization satisfies certain requirements, 
including that the banking organization must have the right to 
terminate the transaction and set off or apply collateral ``promptly 
upon an event of default'' under the bilateral agreement between the 
banking organization and its client. We further understand from 
comment letters submitted on CMESC's application for registration as 
a clearing agency that if a covered Member is unable to meet these 
requirements, it must hold capital without regard to such collateral 
or offsetting transactions, i.e., against its ``gross exposure'' to 
the customer and further, that the significant costs associated with 
gross exposure capital calculations could make the costs of offering 
clearing services to clients prohibitively expensive for relevant 
Members. See e.g. letter from Allison Lurton, General Counsel and 
Chief Legal Officer, FIA, dated Mar. 10, 2025, on SEC Notice of 
Filing of an Application for Registration as a Clearing Agency Under 
Section 17A of the Securities Exchange Act of 1934 [Release No. 34-
102200 (Jan. 15, 2025), 90 FR 7713 (Jan. 22, 2025); File No. 600-
44].
---------------------------------------------------------------------------

    Thus, CMESC is filing the proposed rule change to address each of 
these considerations for prospective Members. Specifically, the 
proposed modifications will enhance Members' abilities to enforce 
contractual termination rights and contractual liens against a User's 
margin or other funds held by CMESC (subordinate to CMESC's rights 
thereto) that Members may have under their contractual arrangements 
with their authorized Users, provided that neither the authorizing 
Member nor its User is in Default to CMESC. The proposed rule change 
will also further strengthen and clarify a Member's ability to 
participate in the liquidation of an authorized User's positions in the 
event of the User's Default.
    The proposed changes are described in detail as follows.
Description of the Proposed Rule Change
1. Proposed Changes Relating to a Member's Contractual Termination 
Rights Outside an Authorized User's Default to CMESC
    CMESC proposes two changes to its Rules to further facilitate a 
Member's enforcement of its contractual termination rights in relation 
to a User it authorizes. First, CMESC proposes adopting new Rule 316 
(Member Exercise of Contractual Rights Against an Authorized User), 
which sets out a process whereby a Member may, pursuant to a request to 
CMESC and subject to certain conditions, immediately assume an 
authorized User's positions pursuant to the Member's contractual 
termination rights, provided that neither the User nor the Member is in 
Default to CMESC. Second, CMESC proposes changes to Rule 602 
(Submission of Transaction Data) to recognize explicitly that a Member 
may submit transactions for an authorized User's Account if the User 
has given the Member the authority to do so, provided again that 
neither the User nor the Member is in Default. The proposed changes to 
Rule 602 will cover trade submission by a Member both as a routine 
matter and as a potential means for a Member to exercise contractual 
termination rights in relation to an authorized User by submitting 
liquidating transactions for the authorized User's Account.
    As noted, proposed Rule 316 sets out the process and conditions for 
a Member to assume an authorized User's positions pursuant to 
contractual termination rights as between the Member and the User. 
Proposed Rule 316(a) applies to the circumstance when a User is in 
default to its authorizing Member, or is otherwise subject to a 
termination event, under one or more binding agreements between the 
Member and User and neither party is in Default (as that term is 
defined in the Rules). Proposed Rule 316(a) introduces the term 
``Contractual Terms'' to refer to such binding agreement(s) and the 
terms ``Affected Member'' and ``Affected User'' to refer to the Member 
and to the User, respectively, when this circumstance arises. It also 
introduces the term ``Affected User Account'' for purposes of proposed 
Rule 316 and defines the term separately in relation to an Affected 
User that is a Supported User and an Affected User that is an 
Independent User. When the Affected User is a Supported User, the 
Affected User Account is the Account that CMESC maintains in the name 
of the Affected Member for the exclusive benefit of the Affected 
Supported User. For an Independent User as the Affected User, the term 
covers the Independent User's Account associated with the Affected 
Member's authorization of the User.
    Proposed Rule 316(b) sets out that an Affected Member may submit a 
written request to CMESC, in such form as CMESC may prescribe, to 
promptly transfer all the positions in Eligible Securities Transactions 
in the Affected User Account to the Account of the Affected Member. The 
Member's request may also request the transfer of initial margin or 
other funds in the Affected User Account to the Account of the Affected 
Member. CMESC will promptly effect the requested transfer, provided the 
conditions set out in other paragraphs of Rule 316 are met. Proposed 
Rule 316(b) explicitly sets out that each Eligible Securities 
Transaction that is transferred is novated to the Affected Member, such 
that the transaction is terminated in the Affected User's Account and 
an equivalent position is established as a cleared position booked to 
the Account of the Affected Member, with the Affected Member 
substituted as CMESC's counterparty to the Eligible Securities 
Transaction.
    Proposed Rule 316(c) sets out the condition that transfers pursuant 
to the proposed Rule will only occur if the Affected User is not in 
Default to CMESC at the time of the request or at the time the 
transfers are to be effected. If a User is subject to a Default to 
CMESC under the Rules, CMESC's default management rules will govern 
and, as acknowledged in this part of the proposed Rule, the authorizing 
Member(s) will have the opportunity to close-out the Defaulting User's 
positions as permitted under and in accordance with the proposed 
changes to Rule 405(c) and Rule 1507(b), as explained below.
    Proposed Rule 316(d) sets forth certain conditions that apply when 
an Affected Member submits a written request to transfer the Affected 
User's positions pursuant to the Rule. A Member's request to transfer 
an Affected User's positions pursuant to proposed

[[Page 34669]]

Rule 316 is deemed by CMESC to constitute an election of the Member to 
terminate its Authorization Agreement with the User with immediate 
effectiveness, and thus, the Member is ceasing to authorize the 
Affected User. Proposed Rule 316(d) also eliminates the need for the 
Member to separately submit advance notice of termination of the 
Authorization Agreement pursuant to Rule 311(d) (Notice of Termination 
of User Authorization).
    The predicate for proposed Rule 316 is that the Member requesting 
the transfer of the Affected User's positions has the contractual right 
to do so under the Contractual Terms. CMESC is not a party to the 
Contractual Terms, and the negotiation of such terms is a commercial 
matter between the Member and its authorized User. Accordingly, Rule 
316(d) sets out that when an Affected Member submits a written request 
to CMESC to effect a transfer pursuant to this Rule, the Affected 
Member is deemed to represent, warrant and covenant to CMESC that the 
Affected User is in default to the Affected Member, or subject to a 
termination event, under the Contractual Terms, and that it has the 
authority under the Contractual Terms to request CMESC to take such 
action. The Affected Member also is deemed to represent to CMESC that 
the Affected Member has reasonably determined that it will be able to 
meet its initial margin and other obligations on all positions in its 
Member Account following completion of the transfer of positions to 
such Account covered by the request, and that its exercise of its 
rights under the Contractual Terms and Rule 316 is consistent with, and 
does not and will not cause the Affected Member to be in violation of, 
its obligations to the Affected User under applicable law.
    It is important that CMESC be protected in the event a dispute 
arises between an Affected Member and Affected User when CMESC acts 
upon the Affected Member's request given that CMESC is adopting Rule 
316 to facilitate a Member's rights under Contractual Terms between the 
Affected Member and Affected User to which CMESC is not a party. 
Indeed, the Contractual Terms may well govern aspects of the 
relationship between a Member and a User beyond the Member's 
authorization of the User or even extend to relationships with or among 
their respective affiliates. Thus, proposed Rule 316(e) sets out that 
CMESC has no liability to the Affected Member or the Affected User for 
any loss or costs that they may incur in connection with the transfer 
of any positions from the Affected User Account to the Account of the 
Affected Member pursuant to the proposed Rule. Proposed Rule 316(e) 
also provides that the Affected Member will indemnify CMESC and its 
affiliates and their respective officers, employees and agents against 
any and all losses, liabilities, damages, claims, costs or expenses 
they may suffer or incur arising out of or in connection with any 
dispute between the Affected Member and Affected User regarding any 
action taken or not taken pursuant to proposed Rule 316.
    As noted, as an alternative to the transfer of all the positions in 
Eligible Securities Transactions in the Affected User Account, CMESC 
also proposes changes to Rule 602 to facilitate a Member's ability to 
liquidate an authorized User's transactions pursuant to its contractual 
termination rights by submitting liquidating transactions for the 
authorized User's Account associated with the Member's authorization. 
Specifically, CMESC is proposing to add a new sentence to existing Rule 
602 to provide that transaction data may be submitted by a Member for 
the Account of a User that it authorizes, provided that the User is not 
in Default. CMESC believes it is beneficial to clarify explicitly in 
Rule 602 that a Member may submit transaction data for the Account of a 
User that it authorizes only when the User is not in Default. This is 
consistent with proposed Rule 316(c), which provides that CMESC will 
not effect any transfer of positions in the Affected User's Account to 
the Affected Member's Account if the Affected User is subject to a 
Default under the Rules. CMESC believes that if an authorized User is 
in Default, no transaction data should be submitted to the Defaulting 
User's Account and the Rules regarding default management, e.g., Rule 
405(c) and 1507(b), should apply to facilitate the prompt close-out 
(e.g., liquidation) of the Defaulting User Positions, as described 
below.
    In addition, a Member could submit transactions on behalf of an 
authorized User either as a routine matter or in connection with 
contractual termination rights pursuant to the proposed changes to Rule 
602. To assure the Member has the authority to submit transactions for 
the User's Account, proposed changes to Rule 602 set out that, when the 
Member submits transaction data for an authorized User, the Member is 
deemed to represent that it has the authority to do so. As the Member's 
authority to submit transactions for a User it authorizes is a matter 
between the Member and authorized User, the proposed changes to Rule 
602 further provide that the Member indemnifies CMESC and its 
affiliates and their respective officers, employees and agents against 
any and all losses, liabilities, damages, claims, costs or expenses 
they may suffer or incur arising out of or in connection with any 
dispute between the Member and User regarding such action taken by the 
Member.
2. Proposed Changes Relating to a Member's Subordinate Security 
Interest in User Collateral
    This section describes CMESC's proposed modifications to its Rules 
with respect to a Member's rights to margin or other funds posted to 
the User Account of a User it has authorized. The purpose of the 
proposed changes is to establish explicit structures whereby the 
authorizing Member will have a claim to the return of any excess margin 
of the User associated with the Member's authorization that remain 
following CMESC's default management process for a Defaulting User or 
following the termination of a Member's authorization of a User and 
satisfaction of the User's obligations to CMESC. The legal approach 
differs for a Supported User and an Independent User, each of which is 
discussed below.
    First, CMESC is proposing modifications to Rule 513, which governs 
the treatment of margin deposited with CMESC for Supported User 
Accounts, to add new paragraph (c) to provide explicitly that CMESC 
will maintain a Supported User Account as a ``securities account'' 
under Article 8 of the New York Uniform Commercial Code (proposed Rule 
513(c) uses the defined term ``NY UCC'') and that CMESC is the 
securities intermediary in relation to the Member that establishes the 
Supported User Account in its name for the benefit of the Supported 
User of the Member.
    As explained above, the authorizing Member for a Supported User is 
responsible for posting initial margin (and Outstanding Exposure 
Settlement) for the Account of the Supported User. Thus, as set out in 
existing Rule 513, CMESC will establish within its books and records a 
Supported User Account for each Supported User of the authorizing 
Member, in the name of the Member for the benefit of the Supported 
User.\17\ Under existing Rule 504

[[Page 34670]]

(Corporation Lien), each Member and each User grants to CMESC to secure 
its obligations to CMESC a first priority and unencumbered security 
interest and lien against any property, cash, securities, or collateral 
deposited with, held by, pledged to, or otherwise available to, CMESC 
by such Member or User, and thus, CMESC has a first priority and 
unencumbered security interest in and lien against the initial margin 
and other funds deposited in the Supported User Account. By providing 
that CMESC will maintain a Supported User Account as a ``securities 
account'' under Article 8 of the NY UCC and that CMESC is the 
securities intermediary in relation to the Member that establishes the 
Supported User Account for the benefit of the Supported User, the 
Member will be the entitlement holder for the Supported User Account 
and be entitled to the return of any excess margin or other funds 
remaining following CMESC's default management process and termination 
of the Member's authorization of the Supported User and satisfaction of 
CMESC's first priority claim.
---------------------------------------------------------------------------

    \17\ See Rule 513(b)(i). If the authorizing Member is a broker-
dealer, CMESC will also maintain a master grouping of the Supported 
User Accounts designated as a ``Special Account for the Exclusive 
Benefit of the Supported Users as Customers of [name of broker-
dealer Member].'' See Rule 513(b)(iv).
---------------------------------------------------------------------------

    Proposed Rule 513(c) also clarifies that all margin, whether in the 
form of cash or Qualified Margin Securities, or other funds credited to 
the Supported User Account for the benefit of a Supported User of the 
Member are treated as ``financial assets'' within the meaning of 
Article 8 of the NY UCC, that New York is the ``securities 
intermediary's jurisdiction'' for purposes of the NY UCC, and that New 
York law will govern all issues specified in Article 2(1) of the Hague 
Securities Convention (which if not overridden means the Hague 
Securities Convention would determine the law applicable to such 
issues).\18\ As a related change, CMESC is proposing to add a 
definition to Rule 101 of the term ``NY UCC,'' which is used in 
proposed new paragraph (c) of Rule 513. As defined, the term means 
``the Uniform Commercial Code enacted by the State of New York as in 
effect from time to time.''
---------------------------------------------------------------------------

    \18\ Article 2(1) of the Hague Securities Convention states: 
This Convention determines the law applicable to the following 
issues in respect of securities held with an intermediary--(a) the 
legal nature and effects against the intermediary and third parties 
of the rights resulting from a credit of securities to a securities 
account; (b) the legal nature and effects against the intermediary 
and third parties of a disposition of securities held with an 
intermediary; (c) the requirements, if any, for perfection of a 
disposition of securities held with an intermediary; (d) whether a 
person's interest in securities held with an intermediary 
extinguishes or has priority over another person's interest; (e) the 
duties, if any, of an intermediary to a person other than the 
account holder who asserts in competition with the account holder or 
another person an interest in securities held with that 
intermediary; (f) the requirements, if any, for the realisation of 
an interest in securities held with an intermediary; (g) whether a 
disposition of securities held with an intermediary extends to 
entitlements to dividends, income, or other distributions, or to 
redemption, sale or other proceeds.
---------------------------------------------------------------------------

    A different approach is taken with respect to Independent Users, as 
they will establish Accounts in their own name with CMESC and are 
responsible for posting initial margin (and Outstanding Exposure 
Settlement) directly to CMESC. Thus, CMESC is proposing new Rule 317 
under which CMESC will recognize and accommodate the grant of a second 
priority security interest to a Member by an authorized Independent 
User in initial margin or other funds credited to the User's 
Independent User Account.
    Under proposed Rule 317, a Member and an Independent User 
authorized by the Member may enter into an Authorization Agreement or 
other appropriate related agreement (such as a control agreement) that 
contains a provision whereby the authorized Independent User grants the 
Member a second priority security interest and lien against any initial 
margin or other funds credited to the relevant Independent User 
Account. For purposes of proposed Rule 317, such credited initial 
margin or other funds are referred to as the ``Independent User 
Funds.'' As provided in proposed Rule 317(a), the agreement under which 
the security interest is granted must contain certain minimum terms 
described below to assure that the agreement does not contain terms 
that conflict with CMESC's first priority security interest in and lien 
against such funds or CMESC's application of such funds in connection 
with the management of any Default of the Independent User.
    First, in order for CMESC to recognize the Member's second priority 
security interest in the Independent User Funds, the agreement between 
the Member and authorized Independent User must contain the Member's 
acknowledgment of CMESC's first priority and unencumbered security 
interest in and lien against property, cash, securities, or collateral 
deposited with, held by, pledged to, or otherwise available to CMESC to 
secure the Independent User's obligations to CMESC created under Rule 
504 (Corporation Lien). This acknowledgement reinforces CMESC's 
priority claim to Independent User Funds ahead of the authorizing 
Member under the Rules and is intended to avoid competing claims to 
Independent User Funds between CMESC and the authorizing Member.
    Second, consistent with the Member's required acknowledgment of 
CMESC's first priority and unencumbered security interest and lien 
described above and again in the context of CMESC recognizing a 
Member's second priority security interest, the agreement between the 
Member and authorized Independent User must provide that the Member 
will ``exercise control over the Independent User Funds only following 
(A) the occurrence of a User Default of the Independent User and 
subject to the condition that the Member will refrain from taking any 
action that could interfere with the Corporation's management of such 
User Default (it being understood that the Member's election to 
participate in the management of the User Default pursuant to and in 
accordance with Rule 405(c) and Rule 1507(b) does not constitute 
interference) or (B) following the effective date of termination of the 
Authorization Agreement between the Member and the Independent User and 
satisfaction of all obligations owing to the Corporation relating to 
the Independent User's Account associated with the Member's 
authorization of the Independent User and subject to the condition that 
the Independent User is not in Default.'' (As explained in the 
following section, CMESC is proposing revisions to Rules 405(c) and 
1507(b).) These are important contractual terms that reinforce CMESC's 
priority claim to apply Independent User Funds under the Rules and are 
intended to avoid competing claims to Independent User Funds between 
CMESC and the authorizing Member.
    Third, the agreement must provide that ``the Member will assert its 
security interest and lien only over those Independent User Funds that 
may remain following, as applicable, (A) completion of the 
Corporation's management of the Independent User's User Default or (B) 
closing of the Independent User's Account associated with the Member's 
authorization of the Independent User and satisfaction of all 
obligations related thereto, and (C) the Corporation's exercise in 
either case of its rights pursuant to its security interest and lien 
created under Rule 504.'' As with the other minimum required terms, 
these are important contractual terms that reinforce CMESC's priority 
claim to apply Independent User Funds under the Rules and are intended 
to avoid competing claims to Independent User Funds between CMESC and 
the authorizing Member.
    For clarity, CMESC is including paragraph (b) in proposed Rule 317 
to reaffirm that an Independent User may not grant any party a security 
interest in or lien against the initial margin or other funds credited 
to its User Account to

[[Page 34671]]

any person other than CMESC or its authorizing Member associated with 
the User Account, and may only grant the lien to the authorizing Member 
in accordance with Rule 317.
    Finally, paragraph (c) of proposed Rule 317 provides that CMESC 
will ``cooperate with the Member and Independent User to execute such 
documents as the Member may reasonably request to perfect its security 
interest and enforce its lien, provided, however, that any such 
documentation and the terms thereof must be acceptable to the 
Corporation in its sole discretion.'' This provision recognizes that 
CMESC may have to execute documentation (such as a control agreement) 
to enable the Member to perfect its secondary security interest in and 
have an enforceable lien against the Independent User Funds 
(subordinate to CMESC's) and confirms that CMESC will cooperate with 
the Member to give effect to the purpose of proposed Rule 317, provided 
the terms of the documentation are acceptable to CMESC, e.g., that they 
are consistent with (or as appropriate contain) the minimum required 
terms described above.
3. Proposed Changes Relating to a Member's Rights To Participate in the 
Liquidation of an Authorized User's Positions in the Event of the 
User's Default
    CMESC is proposing changes to three Rules to further delineate and 
clarify a Member's right to participate in the close-out of an 
authorized User's positions in the event of the User's Default: (i) 
changes to Rule 405(c) (User Default); (ii) related conforming and 
clarifying changes to Rule 1507(b); and (iii) changes to the definition 
of the term ``close-out'' in Rule 101.
    Rules 405 and 1507 together address the process that CMESC will 
follow in the event of the Default of a Member or User. CMESC is 
proposing changes to Rule 405 and related changes to Rule 1507(b) to 
set out explicitly that CMESC will promptly provide an authorizing 
Member the opportunity to participate in the close-out of the 
Defaulting User's positions on CMESC's behalf and to provide more 
detail with respect to how the Member may participate and the Member's 
obligations if it elects to participate. CMESC believes there are 
benefits both to CMESC and to the Member for the Member of an 
authorizing User to have the opportunity to participate in the close-
out of the positions of a Defaulting User it has authorized, given the 
Member's obligation under Rule 406(b)(iii) to cover any losses that 
exceed the Defaulting User's initial margin and other assets available 
to CMESC and the incentive that creates for the Member to seek to 
minimize losses in closing out the Defaulting User's positions on 
CMESC's behalf.
    Also, a core objective in managing the Default of a User is that 
the Defaulting User's positions be closed out promptly. Although this 
is implicit in Rule 405, to provide clarity and certainty, CMESC 
proposes to set out explicitly in Rule 405(c) that when the authorizing 
Member declines to close out the positions, CMESC will liquidate them 
promptly in accordance with the Rule. The proposed changes to Rule 
1507(b) reiterate the prompt liquidation standard, both when CMESC is 
responsible for closing out the positions and when the authorizing 
Member participates in the close-out.
    CMESC is proposing numerous changes in Rule 405(c), which governs a 
User Default. CMESC is proposing to modify subparagraph (c)(i) to set 
out explicitly that CMESC will, pursuant to Rule 1507(b), promptly 
notify each authorizing Member of a Defaulting User that the Member may 
participate in the close-out of the positions in each User Account 
associated with the Member's authorization. Proposed Rule 405(c)(i) 
refers to the positions of a Defaulting User in each User Account 
associated with the Member's authorization as the ``Defaulting User 
Positions.'' CMESC also proposes changes to clarify that after CMESC 
notifies a Member of its opportunity to participate in closing out the 
Defaulting User Positions on behalf of CMESC, the Member should 
promptly respond within the period CMESC prescribes and will be deemed 
to decline the opportunity to participate if the Member has not 
responded within such time.
    CMESC is also proposing to delete the last sentence in Rule 
405(c)(i), which sets out that a Member that agrees to liquidate the 
Defaulting User's portfolio on behalf of CMESC ``will be directly and 
primarily responsible for meeting the financial and settlement 
obligations of the Corporation with respect to open positions of the 
Defaulting User authorized by that Member.'' Upon further 
consideration, CMESC believes that this sentence may create ambiguity 
in relation to a Member's potential obligation under Rule 406(b)(iii) 
to cover any losses that exceed the Defaulting User's initial margin 
and other assets available to CMESC, which is the operative standard, 
in the event of the Default of a User it has authorized. This sentence 
also becomes unnecessary in light of the other proposed changes to Rule 
405, explained below.
    CMESC proposes adding new subparagraph (ii) to Rule 405(c) to 
provide additional detail regarding how a Member may participate in the 
close-out of the Defaulting User Positions if it elects to do so. As 
set forth in proposed Rule 405(c)(ii), the Member may participate in 
the manner established in this part of the Rule (i.e., Rule 405(c)(ii) 
and its subparts) or in another manner, both of which would be 
determined in consultation with CMESC. Proposed Rule 405(c)(ii) sets 
out two manners for a Member to participate in the close-out of the 
Defaulting User Positions. As provided in subparagraph (A), the 
Defaulting User Positions could be liquidated promptly in the 
Defaulting User's Account and reestablished in the Member's Account, 
whereby positions equivalent to the liquidated Defaulting User 
Positions (i.e., equivalent to the cleared positions in the Defaulting 
User's Account) are novated to the Member and established as cleared 
positions booked to the Member's Account. Under this approach, the 
following conditions must be met.
    <bullet> First, because the Member will be party to the positions 
reestablished in the Member's Account (i.e., positions equivalent to 
those that were cleared in the Defaulting User's Account), the Member 
must represent to CMESC that the Member will be able to meet its 
initial margin and settlement obligations on all positions in its 
Member Account following reestablishment of the Defaulting User 
Position in its Member Account under proposed Rule 405(c)(ii)(A)I.
    <bullet> Second, proposed Rule 405(c)(ii)(A)II. sets out that the 
Member, acting in a commercially reasonable manner and consistent with 
market convention, is responsible for determining the liquidation value 
of the portfolio of the Defaulting User Positions as of the date the 
positions are liquidated and reestablished in the Member's Account as 
equivalent cleared positions, which date is referred to for purposes of 
Rule 405(c)(ii) as the ``Liquidation Date.'' Promptly following the 
Liquidation Date, the Member must provide a detailed written statement 
to CMESC, with supporting documentation, of the Member's calculation of 
such liquidation value, which must be satisfactory to CMESC. As between 
the Defaulting User and CMESC, if as of the Liquidation Date the 
liquidation value is less than the value of the portfolio of positions 
that are reestablished in the Member's Account (which as noted are 
reestablished as positions equivalent to those that were cleared in the 
Defaulting User's Account), the difference is fixed as the

[[Page 34672]]

amount of the losses on such positions and if such liquidation value is 
greater than the value of the portfolio of positions reestablished in 
the Member's Account as of the Liquidation Date, the difference is 
fixed as the amount of gains on such positions.
    <bullet> Finally, consistent with CMESC's rights under Rule 
406(b)(ii) and other Rules to apply initial margin and other assets 
held by CMESC to losses associated with a User's Default, proposed Rule 
405(c)(ii)(A)III. sets out that CMESC will credit the Member for the 
amount of any losses fixed pursuant to Rule 405(c)(ii)(A)II., with such 
amount credited using and limited to the Defaulting User's initial 
margin and other assets CMESC holds in respect of the Defaulting User's 
Account associated with the Member's authorization. If the amount to be 
credited to the Member exceeds the Defaulting User's margin and other 
assets held by CMESC in respect of the Defaulting User's Account, then 
the Member would incur such loss in acquiring the positions, but that 
would be consistent with the Member's obligation under Rule 406(b)(iii) 
to cover the losses that exceed the Defaulting User's initial margin 
and other assets available to CMESC. Conversely, CMESC will debit the 
Member for the amount of any gains fixed pursuant to Rule 
405(c)(ii)(A)II. After the Liquidation Date, any gains or losses on the 
Defaulting User Positions that are liquidated in the Defaulting User's 
Account and reestablished in the Member's Account will belong to the 
Member, as provided in proposed Rule 405(c)(ii)(A)III.
    As provided in proposed Rule 405(c)(ii)(B), the second manner in 
which CMESC proposes to allow a Member to participate in the close-out 
of the Defaulting User Positions is specific to the liquidation of any 
Defaulting User Position that is a Repo Transaction for which the 
Member is the contra party on the original transaction (i.e., a ``done-
with'' Repo Transaction). In this scenario, the Member may agree to 
terminate the position by accelerating the Off-Leg Settlement Date to a 
new Off-Leg Settlement Date that is on or before a date that CMESC 
specifies, consistent with the core objective that the Defaulting User 
Positions be liquidated promptly. Similar to the process in proposed 
Rule 405(c)(ii)(A) described above, the Member must determine the 
liquidation value of the original (i.e., pre-accelerated) Defaulting 
User Position as of the accelerated Off-Leg Settlement Date, which is 
used as the Liquidation Date, in the same manner as it would calculate 
the liquidation value for positions reestablished in its Account 
pursuant to Rule 405(c)(ii)(A)II. This liquidation value will be used 
to fix the loss or gain on the position as between CMESC and the 
Defaulting User and if multiple Repo Transactions between the Member 
and Defaulting User are accelerated pursuant to proposed Rule 
405(c)(ii)(B), the losses or gains will be determined on an aggregate 
basis for such positions. CMESC will credit or debit the Member for the 
losses or gains fixed pursuant to this Rule 405(c)(ii)(B) in the manner 
provided in Rule 405(c)(ii)(A)III. CMESC believes a Member may find the 
approach outlined in proposed Rule 405(c)(ii)(B) an effective way to 
reduce losses realized upon the close-out of any Defaulting User 
Positions that are ``done-with'' Repo Transactions with the Member and 
is including this approach to provide additional flexibility to 
determine (in consultation with CMESC) the appropriate mean(s) for the 
Member to participate in the close-out of the Defaulting User 
Positions.
    The proposed changes described above to elaborate on how a Member 
may participate in closing out the Defaulting User Positions do not 
change the Member's obligation under Rule 406(b)(iii) to cover any 
losses that exceed the Defaulting User's initial margin and other 
assets available to CMESC. Therefore, CMESC proposes adding a new 
subparagraph (iii) under Rule 405(c) to clarify that the Member's 
obligation under Rule 406(b)(iii) to fully discharge the losses and 
liabilities to CMESC associated with the User's Default in each User 
Account associated with the Member's authorization, once such losses 
and liabilities are finalized, remains in effect, notwithstanding the 
Member's decision to participate in the close-out of the Defaulting 
User Positions. As noted above, Rule 406(b)(iii) is the operative 
provision that governs the Member's potential liability in relation to 
the Default of a User it has authorized.
    CMESC also proposes changes to existing subparagraph (ii) of Rule 
405(c), which is proposed to be renumbered as Rule 405(c)(iv), to align 
with the revised provisions discussed above regarding the actions that 
CMESC will take to close-out, including liquidation of, the Defaulting 
User Positions in relation to any authorizing Member that declines to 
participate in the close-out of the Defaulting User Positions 
associated with the Member's authorization. CMESC proposes to clarify 
that CMESC will promptly initiate the close-out process described in 
the Rules for the User Account of the Defaulting User associated with 
the Member's authorization. CMESC also proposes to delete the last 
sentence, which is a ``for avoidance of doubt'' provision that is 
adequately explained in Rule 406(b)(iii), as described above.
    CMESC also proposes changes to existing subparagraph (iii) of Rule 
405(c), which is proposed to be renumbered as Rule 405(c)(v), to set 
out more directly that CMESC will apply the financial resources 
described in Rule 406(b), in the order provided in and subject to Rule 
406(b), to the Defaulting User's obligations owed to CMESC, regardless 
whether the authorizing Member elects to participate in the close-out 
of the Defaulting User Positions pursuant to Rule 405(c).
    As a result of the proposed changes to Rule 405 described above, 
CMESC is proposing conforming and clarifying changes to Rule 1507(b). 
First, existing Rule 1507(b) provides that in the case of a User 
Default, before CMESC takes any of the actions described in Rule 
1507(e), CMESC will notify the Defaulting User's authorizing Member(s) 
that the Member may ``terminate the Defaulting User's obligations to 
the Corporation by satisfying them in full,'' but subject to the 
qualification ``if time permits.'' CMESC proposes to delete ``if time 
permits'' and ``terminate the Defaulting User's obligations to the 
Corporation by satisfying them in full,'' and to add new text to Rule 
1507(b) to specify that CMESC will promptly notify the authorizing 
Member(s) of the Member's right to close-out the Defaulting User's 
positions pursuant to and in accordance with Rule 405(c), noting 
parenthetically that the Member and CMESC will act promptly to effect 
the close-out.
    Finally, CMESC is proposing clarifying changes to the definition of 
``close-out'' in Rule 101. The current definition covers extinguishing 
a Member's or User's cash receipt entitlement in relation to the sale 
of Eligible Securities under a Repo Transaction. The term is used in 
the proposed changes to Rule 405(c) and 1507(b) in the broader sense of 
liquidating or terminating any cleared Eligible Securities Transaction. 
Thus, CMESC proposes to modify the definition of the term ``close-out'' 
to mean the liquidation or termination of a cleared Eligible Securities 
Transaction. This definition is consistent with how the term is used in 
other CMESC Rules.
2. Statutory Basis
    For the reasons set forth below, CMESC believes the proposed rule 
change is consistent with Section 17A of

[[Page 34673]]

the Act,\19\ SEC Rule 17ad-22(e)(13),\20\ SEC Rule 17ad-22(e)(18),\21\ 
SEC Rule 17ad-22(e)(19),\22\ and SEC Rule 17ad-22(e)(21)(i).\23\

    \23\ 17 CFR 240.17ad-22(e)(21)(i).
---------------------------------------------------------------------------

Consistency With Section 17A(b)(3)(F) of the Act
    Section 17A(b)(3)(F) of the Act requires, in part, that the rules 
of a clearing agency be designed to promote the prompt and accurate 
clearance and settlement of securities transactions, to remove 
impediments to and perfect the mechanism of a national system for the 
prompt and accurate clearance and settlement of securities 
transactions, and, in general, to protect investors and the public 
interest.\24\ CMESC believes that the proposed rule change is 
consistent with Section 17A(b)(3)(F) of the Act because it will further 
support Members' management of risks associated with authorizing 
persons as Users and enhance Members' ability to authorize Users by 
addressing potential constraints imposed by bank regulatory capital 
requirements and enhancing Members' abilities to enforce contractual 
termination rights and secondary lien rights against authorized Users' 
margin or other funds held by CMESC that Members may have under their 
contractual arrangements with their authorized Users. The proposed rule 
change will also further strengthen and clarify a Member's ability to 
participate in the liquidation of an authorized User's positions in the 
event of the User's Default. These modifications will thus support 
Members' ability to participate in and authorize Users in CMESC's 
Clearing Services, which will promote the prompt and accurate clearance 
and settlement of transactions in or involving U.S. Treasury securities 
(including eligible secondary market securities transactions that 
market participants may be required to centrally clear pursuant to the 
rules of a covered clearing agency adopted pursuant to SEC Rule 17ad-
22(e)(18)(iv)).\25\

    \25\ 17 CFR 240.17ad-22(e)(18)(iv).
---------------------------------------------------------------------------

Consistency With Rule 17ad-22(e)(13)
    SEC Rule 17ad-22(e)(13) requires, in part, that the rules of a 
covered clearing agency be reasonably designed to ensure the covered 
clearing agency has the authority and operational capacity to take 
timely action to contain losses and liquidity demands and continue to 
meet its obligations. CMESC believes that the proposed rule change is 
consistent with Rule 17ad-22(e)(13) because the proposed changes to 
Rule 405(c) and Rule 1507(b) are designed to achieve the core objective 
in default management that the Defaulting User's positions be closed 
out promptly to minimize losses and liquidity demands and continue to 
meet CMESC's settlement obligations. The requirement to take prompt 
action to close-out, including liquidate, the Defaulting User's 
positions is reflected in multiple places in the proposed rule change. 
Specifically, proposed Rule 405(c) provides that CMESC will promptly 
notify each authorizing Member of a Defaulting User that the Member may 
participate in closing out the positions in each User Account 
associated with the Member's authorization. CMESC also proposes changes 
to clarify that, after CMESC notifies a Member of its opportunity to 
participate in closing out the Defaulting User Positions, the Member 
should promptly respond within the period CMESC prescribes and will be 
deemed to decline the opportunity if the Member has not responded 
within such time. In addition, proposed Rule 405(c)(ii) provides two 
non-exclusive manners in which authorizing Members may participate in 
closing out positions of Defaulting Users they authorize, both 
requiring that the Defaulting User Positions be closed out promptly and 
that the Member provide a detailed written statement of its calculation 
of the liquidation value promptly following the Liquidation Date. 
Similarly, if the authorizing Member declines to participate in the 
close-out of the Defaulting User's positions associated with the 
Member's authorization, proposed Rule 405(d)(iv) requires CMESC to 
promptly initiate the close-out process described in the Rules for the 
User Account of the Defaulting User. Finally, proposed changes to Rule 
1507(b) specify that CMESC will ``promptly'' notify the authorizing 
Member of the Member's right to close-out the Defaulting User's 
positions and make clear that the Member and CMESC will act promptly to 
effect the close-out pursuant to and in accordance with proposed 
changes to Rule 405(c).
    All of the above proposed changes are reasonably designed to ensure 
that CMESC will have the authority and operational capacity to take 
timely action to promptly close-out a Defaulting User's positions. In 
addition, as described in detail above, by proposing changes to Rule 
405(c) to provide the authorizing Member the opportunity to participate 
in a prompt close-out of the User's positions, CMESC believes that the 
proposed changes to Rule 405(c) will help minimize losses from the User 
Default and, thus, contain losses and liquidity demands, enabling CMESC 
to continue to meet its obligations. Therefore, CMESC believes that the 
proposed rule change is consistent with SEC Rule 17ad-2(e)(13).
Consistency With Rule 17ad-22(e)(18)(iv)(C)
    CMESC believes that the proposed rule change is consistent with SEC 
Rule 17ad-22(e)(18)(iv)(C), which requires, in part, a covered clearing 
agency that provides central counterparty services for transactions in 
U.S. Treasury securities to ensure that it has appropriate means to 
facilitate access to clearance and settlement services for eligible 
secondary market transactions in U.S. Treasury securities, including 
those of indirect participants such as Independent Users and Supported 
Users. As detailed above, the proposed rule change consists of (i) 
proposed new Rule 316 and proposed changes to Rule 602 designed to 
support Members' risk management and enhance their ability and capacity 
to authorize persons as Users, by providing Members the clear means to 
enforce contractual termination rights under their contractual 
arrangements with authorized Users in circumstances when the authorized 
Users are not in Default under CMESC's Rules; (ii) proposed changes to 
Rule 513 to create a legal structure to provide an authorizing Member 
with a securities entitlement under the NY UCC to excess assets in the 
Supported User Account associated with such Member's authorization and 
proposed new Rule 317 to provide a Member the means to obtain and 
perfect a secondary security interest in and lien against Independent 
User Funds held by CMESC for the Independent User Account associated 
with the Member's authorization, while affirming CMESC's first priority 
and unencumbered security interest in and lien against the Independent 
User funds; and (iii) proposed changes to Rules 405(c) and 1507(b) 
designed to strengthen and clarify Members' abilities to participate in 
the close-out of positions of Users they authorize in the event of an 
authorized User's Default. These proposed changes are designed to 
enhance the ability and capacity of Members to authorize Users, which 
will support CMESC's efforts to attract and to on-board Members and 
Users prior to CMESC commencing operations of its Clearing Services and 
on an ongoing basis thereafter and enhance access to

[[Page 34674]]

CMESC's Clearing Services for prospective Members and Users. As such, 
CMESC believes that the proposed rule change is reasonably designed to 
provide appropriate means to facilitate access to clearance and 
settlement services for eligible secondary market transactions in U.S. 
Treasury securities, including those of indirect participants, 
consistent with Rule 17ad-22(e)(18)(iv)(C).
Consistency With Rule 17ad-22(e)(19)
    SEC Rule 17ad-22(e)(19) requires that the rules of a covered 
clearing agency identify, monitor and manage material risks to the 
clearing agency arising from arrangements that indirect participants 
have with direct participants to access the clearing agency's clearing 
and settlement services. The existing Rules define a Member's rights 
and obligations with respect to any User it authorizes while at the 
same time recognizing (in Rule 306(c)) that a Member and an authorized 
User may enter into separate commercial terms between them. Those 
features are unchanged. Rather, the proposed rule change provides a 
means for a Member to enforce contractual liquidation rights and any 
secondary rights to User collateral it may negotiate with an authorized 
User, subject to terms that protect CMESC's ability to manage risk 
pursuant to its Rules. In this respect, as conditions to liquidate an 
authorized User's positions under proposed Rule 316 or under Rule 602 
as proposed to be revised, a Member represents that it has the 
contractual authority to do so and indemnifies CMESC and related 
parties against any losses, liabilities, damages, claims or expenses 
they may incur arising out of any dispute between the Member and its 
authorized User or in the case of action under proposed Rule 316 
regarding any action taken or not taken pursuant to that Rule. With 
respect to a Member's rights to collateral of an authorized User, the 
proposed rule change establishes structures whereby the Member's claim 
is secondary to CMESC's rights as explained above. In this respect, a 
Member's claim to such collateral is limited to the return of any 
excess margin or other funds remaining following CMESC's default 
management process if the User is in Default or following termination 
of the Member's authorization of the User and satisfaction of the 
User's obligations to CMESC. For these reasons, CMESC believes that the 
proposed rule change is appropriate to manage potential risks to CMESC 
arising from arrangements that its Users have with Members and is 
consistent with SEC Rule 27ad-22(e)(19).
Consistency With Rule 17ad-22(e)(21)(i)
    SEC Rule 27ad-22(e)(21)(i) requires that a covered clearing agency 
have clearing and settlement arrangements that are efficient and 
effective in meeting the requirements of its participants and the 
markets the clearing agency services. CMESC believes the proposed rule 
change is consistent with Rule 27ad-22(e)(21)(i), meeting the needs of 
Members and Users, in that it will enhance Members' ability to 
authorize Users by addressing potential constraints imposed by bank 
regulatory capital requirements and will further support the 
enforceability of certain contractual terms that are separately 
negotiated between a Member and an authorized User.

B. CMESC's Statement on Burden on Competition

    Section 17A(b)(3)(I) of the Act \26\ requires that the rules of a 
clearing agency not impose any burden on competition that are not 
necessary or appropriate in furtherance of the purposes of the Act. 
CMESC believes that the proposed rule change would not impose a burden 
on competition that is not necessary or appropriate in furtherance of 
the purposes of the Act. CMESC believes that the proposed rule change 
may enhance competition because, as detailed above, the proposed rule 
change would further support Members' risk management of Users they 
authorize and enhance Members' ability and capacity to authorize Users, 
thereby facilitating access to CMESC's Clearing Services for eligible 
secondary market transactions in U.S. Treasury securities. CMESC also 
believes that the proposed rule change would indirectly benefit Users 
and prospective Users by enhancing their abilities to access CMESC by 
supporting Members' capabilities to authorize Users.
---------------------------------------------------------------------------

    \26\ 15 U.S.C. 78q-1(b)(3)(I).
---------------------------------------------------------------------------

    CMESC recognizes that various Members may perceive varying degrees 
of benefits of the proposed rule change conferred on them, depending on 
each Member's regulatory status and its entity type. CMESC believes 
that the effect of the proposed rule change on competition is 
distributed equally among all types of prospective Members because it 
will apply to all Member types and would not disadvantage or favor any 
particular type of Member in relationship to the other types of 
potential Members. As such, CMESC believes that the proposed rule 
change would promote competition and does not impose any burden on
