(A) Clearing Agency's Statement of the Purpose of, and Statutory Basis 
for, the Proposed Rule Change

1. Purpose
Executive Summary of Proposed Changes
    On October 25, 2024, the Commission adopted amendments to the CCAS 
Rules to add new requirements related to the collection of intraday 
margin by a covered clearing agency (``CCA'').\4\ Specifically, the 
Commission amended Rule 17ad-22(e)(6)(ii) \5\ to establish new 
requirements with respect to a CCA's policies and procedures regarding 
the collection of intraday margin to: (i) include a new requirement to 
monitor intraday exposures on an ongoing basis; (ii) modify the 
preexisting reference to making intraday calls ``in defined

[[Page 17492]]

circumstances'' to making intraday calls ``as frequently as 
circumstances warrant'' and identifying examples of such circumstances; 
and (iii) require that a CCA document when it determines not to make an 
intraday margin call pursuant to its written policies and 
procedures.\6\ As described below, the proposed changes to the NSCC 
Rules are primarily designed to facilitate compliance with these 
requirements.

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

Background
    NSCC is a clearing agency that provides clearing, settlement, risk 
management, and central counterparty services for trades involving 
equity securities, corporate and municipal debt, exchange traded funds 
and unit investment trusts. NSCC manages its credit exposure to its 
Members by determining the appropriate Required Fund Deposit to the 
Clearing Fund for each Member and by monitoring the sufficiency of such 
deposits, as provided for in the NSCC Rules.\7\
---------------------------------------------------------------------------

    \7\ See NSCC Rule 4, supra note 3.
---------------------------------------------------------------------------

    The objective of a Member's Required Fund Deposit is to mitigate 
potential losses to NSCC associated with liquidating a Member's 
portfolio in the event NSCC ceases to act for that Member (hereinafter 
referred to as a ``default'').\8\ Required Fund Deposits operate, 
individually, as the Member's margin, and the aggregate of all such 
Members' deposits is referred to, collectively, as the Clearing Fund, 
which operates as NSCC's default fund. NSCC would access the Clearing 
Fund should a defaulting Member's own Required Fund Deposit be 
insufficient to satisfy losses to NSCC caused by the liquidation of 
that Member's portfolio.
---------------------------------------------------------------------------

    \8\ The NSCC Rules identify when NSCC may cease to act for a 
Member and the types of actions NSCC may take. See NSCC Rule 46 
(Restrictions on Access to Services), supra note 3.
---------------------------------------------------------------------------

    Each Member's Required Fund Deposit amount consists of a number of 
applicable components, each of which is calculated to address specific 
risks faced by NSCC, as identified within the Rules. The major 
components of NSCC's Clearing Fund charges include, but are not limited 
to: (i) volatility charges for securities based on asset type and 
liquidity profile; (ii) mark-to-market charges; (iii) fail charges; 
(iv) a charge for Family-Issued Securities to mitigate wrong way risk; 
(v) a charge to mitigate day over day margin differentials; (vi) a 
coverage component; (vii) a margin liquidity adjustment component; 
(viii) a backtesting charge; and (iv) an excess capital premium 
charge.\9\
---------------------------------------------------------------------------

    \9\ See NSCC Procedure XV, supra note 3.
---------------------------------------------------------------------------

Overview of Intraday Monitoring and Margin Collection
    NSCC Procedure XV describes NSCC's Clearing Fund formula and 
methodology. NSCC calculates and collects Clearing Fund from its 
Members (i.e., a Required Fund Deposit) on a daily basis using a risk-
based margin methodology.\10\ A Member's Required Fund Deposit may vary 
daily and is generally based upon the Member's trading activity and 
current unsettled positions. Required Fund Deposit deficits are due to 
NSCC each business day, typically by 10:00 a.m. Eastern Time. In 
addition, NSCC may call for additional margin on an intraday basis, as 
needed.
---------------------------------------------------------------------------

    \10\ Section 12 of NSCC Rule 56 describes the Clearing Fund 
obligations associated with NSCC's Securities Financing Transaction 
Clearing service. Section 12(c) of NSCC Rule 56 specifically 
provides that NSCC calculates the amount of each SFT Member's 
required deposit for its SFT Positions by applying the Clearing Fund 
formula for CNS Transactions in Sections I.(A)(1) (a), (b), (c), 
(e), (f), (g) of NSCC Procedure XV, as well as the additional 
Clearing Fund formula in Section I.(B)(5) (Intraday Mark-to-Market 
Charge) and (6) (Intraday Volatility Charge) of NSCC Procedure XV, 
except as noted otherwise, in the same manner as such sections apply 
to CNS Transactions submitted for regular way settlement. See 
Section 12 of NSCC Rule 56, supra note 3.
---------------------------------------------------------------------------

    Pursuant to Sections I.(B)(5) and (6) of NSCC Procedure XV,\11\ 
NSCC has discretionary authority to collect margin on an intraday basis 
based on changes to a Member's intraday mark-to-market exposure 
(``Intraday Mark-to-Market Charge'' or ``Intraday MTM Charge'') and 
intraday volatility exposure (``Intraday Volatility Charge'') 
(collectively, ``Intraday Margin Charges''). These procedures describe 
the calculations for the Intraday MTM Charge and Intraday Volatility 
Charge and the thresholds used to trigger the potential collection of 
such charges.
---------------------------------------------------------------------------

    \11\ See Sections I.(B)(5) and (6) of NSCC Procedure XV, supra 
note 3.
---------------------------------------------------------------------------

    The Intraday MTM Charge is based on the difference between the last 
marked-to-market price of a Member's net CNS and Balance Order 
positions (including CNS fails) and the most recently observed market 
price for such positions.\12\ An Intraday MTM Charge may generally be 
imposed if the difference of this calculation meets or exceeds 80 
percent of the ``volatility charge'' component of the Member's start of 
day Clearing Fund requirement.\13\ NSCC may reduce this threshold 
during volatile market conditions if it determines that a reduction of 
the threshold is appropriate to mitigate risks to NSCC.
---------------------------------------------------------------------------

    \12\ See Section I.(B)(5) of NSCC Procedure XV, supra note 3.
    \13\ The ``volatility charge'' component of each Member's 
Required Fund Deposit is designed to measure market price volatility 
of the start-of-day portfolio and is calculated for Members' net 
unsettled positions. See NSCC Procedure XV, Section I.(A)(1)(a) for 
CNS Transactions and Section I.(A)(2)(a) for Balance Order 
Transactions, supra note 3.
---------------------------------------------------------------------------

    The Intraday Volatility Charge is based on the difference between a 
Member's start of day volatility charge and intraday volatility charges 
calculated with respect to its net unsettled CNS and Balance Order 
positions.\14\ An Intraday Volatility Charge may generally be imposed 
if the difference of this calculation meets or exceeds 100 percent and 
the amount that would be collected is greater than $250,000. NSCC may 
reduce the 100 percent threshold, for example during volatile market 
conditions or market events that cause increases in trading volumes, if 
NSCC determines that a reduction of the threshold is appropriate to 
mitigate risks to NSCC.
---------------------------------------------------------------------------

    \14\ See Section I.(B)(6) of NSCC Procedure XV, supra note 3. 
The amount of the charge is reduced by the portion of the margin 
requirement differential charge that represents the volatility 
component collected at the start of the day and excludes the amount 
calculated for long positions in Family Issued Securities and shares 
delivered to or received by the Member to satisfy all or any portion 
of a short or long position.
---------------------------------------------------------------------------

    Intraday market moves and positions are monitored by NSCC on an 
ongoing basis. NSCC conducts intraday monitoring of its exposures for 
purposes of Intraday Margin Charges at 15-minute intervals generally 
between the hours of 10:00 a.m. to 4:30 p.m. Eastern Time, unless such 
intervals are extended by NSCC to address operational or other delays. 
NSCC reviews these intraday snapshots of each Member's portfolio to 
determine whether the Member has experienced an adverse risk exposure 
that warrants NSCC assessing Intraday MTM Charge and/or Intraday 
Volatility Charge.
    Through this filing, NSCC is providing additional clarity and 
transparency in the Rules concerning NSCC's processes for the ongoing 
monitoring, recalculation and collection of Intraday Margin Charges, 
including circumstances in which NSCC may determine not to collect such 
a charge, to facilitate compliance with the newly adopted CCAS Margin 
Rules.\15\ The proposed changes are described in detail below.
---------------------------------------------------------------------------

    \15\ See 17 CFR 240.17ad-22(e)(6)(ii) and supra note 4.
---------------------------------------------------------------------------

Proposed Changes to the NSCC Rules
    NSCC proposes to amend Sections I.(B)(5) and I.(B)(6) of NSCC 
Procedure XV to provide additional clarity and transparency in the NSCC 
Rules concerning NSCC's processes for the

[[Page 17493]]

ongoing monitoring, recalculation and collection of Intraday MTM 
Charges and Intraday Volatility Charges, including circumstances in 
which NSCC may determine not collect such a charge, to facilitate 
compliance with the newly adopted CCAS Margin Rules.\16\ In addition, 
NSCC proposes to adopt new authority to reduce its intraday margin 
thresholds for a given Member to require a Member to make additional 
Intraday MTM or Intraday Volatility Charge payments if NSCC determines 
it to be necessary to protect itself and its Members in response to 
factors such as market conditions or financial or operational 
capabilities affecting such Member. NSCC also proposes clarifying 
changes in Section I.(A) of Procedure XV to note that it may use the 
baseline calculation for the Margin Liquidity Adjustment (``MLA'') 
charge for certain equity exchange-traded fund (``ETF'') positions to 
address circumstances where certain data inputs needed for the 
creation/redemption calculation for MLA are not available. Finally, 
NSCC would make additional clarifying changes to add an introductory 
paragraph in Procedure XV concerning the frequency of its Clearing Fund 
calculations and the potential for extension of such actions. The 
proposed changes are described in detail below.
---------------------------------------------------------------------------

    \16\ See id.
---------------------------------------------------------------------------

Intraday Margin Charges Generally
Proposed Changes Concerning Ongoing Monitoring, Calculation and 
Collection of Intraday Margin Charges
    NSCC proposes to modify Section I.(B)(5) of NSCC Procedure XV to 
provide additional clarity and transparency regarding NSCC's process 
for the ongoing monitoring and recalculation of its intraday mark-to-
market and volatility exposures and the collection of Intraday Margin 
Charges. First, NSCC proposes to consolidate its procedures for 
Intraday Mark-to-Market Charges and Intraday Volatility Charges into 
Section I.(B)(5) of Procedure XV and rename Section I.(B)(5) of 
Procedure XV to reference Intraday Margin Charges generally, rather 
than Intraday Mark-to-Market Charges specifically. NSCC would also add 
a new introductory paragraph to the procedure to describe NSCC's 
intraday monitoring process and general authority to make intraday 
margin calls. The proposed rule would provide that NSCC shall establish 
procedures for the ongoing monitoring and recalculation of its intraday 
mark-to-market and volatility exposures, during such times and at such 
frequency as set forth by NSCC, and that NSCC will communicate to 
Members the timing and frequency with which NSCC monitors and re-
calculates its intraday mark-to-market and volatility exposures by 
posting such information on NSCC's public website.\17\ The proposed 
rule change would also state that NSCC may collect payments from 
Members on an intraday basis based on intraday changes in its risk 
exposures, defined generally as an ``Intraday Margin Charge,'' 
including when certain risk thresholds are breached or when the 
products cleared or markets served display elevated volatility. The 
proposed rule would further clarify that Intraday Margin Charges 
include charges based on re-calculated mark-to-market exposures 
(``Intraday Mark-to-Market Charge'') and volatility exposures 
(``Intraday Volatility Charge'') for each Member, as further defined in 
the Procedure. NSCC would also make a conforming change to Section 
12(c) of NSCC Rule 56 regarding Clearing Fund obligations for SFT 
Positions to reflect the consolidation of its procedures for Intraday 
Mark-to-Market Charges and Intraday Volatility Charges into Section 
I.(B)(5) of Procedure XV.\18\
---------------------------------------------------------------------------

    \17\ As noted above, NSCC currently monitors and recalculates 
its intraday mark-to-market and volatility exposures in 15-minute 
intervals throughout the day.
    \18\ See supra note 10.
---------------------------------------------------------------------------

    The proposed change is intended to provide additional clarity and 
transparency in the NSCC Rules concerning how NSCC facilities 
compliance with requirements in the CCAS Margin Rules that each CCA 
have policies and procedures reasonably designed to (i) monitor 
intraday exposures on an ongoing basis and (ii) make intraday margin 
calls, as frequently as circumstances warrant, including when risk 
thresholds specified by NSCC are breached or when products cleared or 
markets served display elevated volatility.\19\
---------------------------------------------------------------------------

    \19\ See 17 CFR 240.17ad-22(e)(6)(ii)(B) and (C) and supra note 
4.
---------------------------------------------------------------------------

Proposed Changes Concerning Determinations Not To Collect Intraday 
Margin Charges
    NSCC also proposes to amend Section I.(B)(5) of Procedure XV to 
provide additional clarity and transparency around NSCC's process for 
determining whether to collect Intraday Magin Charges. As described 
above, NSCC monitors its intraday mark-to-market and volatility 
exposures in 15-minute intervals throughout the day and has 
discretionary authority to collect Intraday MTM Charges and/or Intraday 
Volatility Charges based on changes to a Member's intraday mark-to-
market and volatility exposures. NSCC considers a number of factors 
when determining whether to collect an Intraday Margin Charge based on 
exposures that breach certain defined thresholds (discussed below) at 
any given 15-minute interval. Accordingly, NSCC proposes to amend 
Section I.(B)(5) of Procedure XV to describe this intraday margin 
assessment process in the NSCC Rules.
    NSCC proposes to add new rule text to the procedure to provide that 
NSCC may determine not to collect an Intraday Margin Charge in 
circumstances where NSCC determines that the intraday exposure of the 
Member and/or breaches of certain thresholds do not accurately reflect 
NSCC's risk exposure to the Member. The proposed rules would also 
provide examples of circumstances that NSCC may consider with respect 
to such a determination, which may include, but are not limited to: (i) 
market conditions and/or portfolio composition result in the defined 
thresholds not being breached on a consistent or persistent basis; (ii) 
trades will be offset by trades submitted later in the day; (iii) the 
defined threshold was met due to the submission of erroneous trades 
that are being corrected; or (iv) the defined threshold was met due to 
erroneous data inputs.
    Additionally, NSCC would adopt new rules stating that any reduction 
or determination not to collect an Intraday Margin Charge, or any 
waiver of an Intraday Volatility Charge (as discussed below), shall be 
approved, documented and reviewed on a regular basis pursuant to NSCC's 
procedures. Pursuant to NSCC's market risk management procedures, 
NSCC's Market Risk Management team monitors Members' open positions and 
exposures on a 15-minute basis throughout the day and identifies 
accounts that exceed certain pre-established thresholds. These 
thresholds trigger research, review and escalation actions, including 
recommendations for making an Intraday Marign Call. If a recommendation 
to collect an Intraday Margin Call is made, this is escalated to more 
senior members of Market Risk Management in accordance with specified 
escalation procedures. If an Intraday Margin Call is not recommended or 
reduced (or with respect to an Intraday Volatility Charge, waived), a 
member of the Market Risk Management team documents this determination 
in accordance with NSCC's market risk management procedures.
    The proposed change is intended to provide additional clarity and 
transparency in the NSCC Rules

[[Page 17494]]

concerning NSCC's Intraday Margin Call determination process and how 
NSCC facilitates compliance with requirements in the CCAS Margin Rules 
that each CCA have policies and procedures reasonably designed to 
document when NSCC determines not to make an intraday call pursuant to 
its written policies and procedures.\20\
---------------------------------------------------------------------------

    \20\ See 17 CFR 240.17ad-22(e)(6)(ii)(D) and supra note 4.
---------------------------------------------------------------------------

Intraday Mark-to-Market Charges
    NSCC proposes clarifying changes to existing procedures in Section 
I.(B)(5) of NSCC Procedure XV concerning the calculation of Intraday 
MTM Charges. First, NSCC would create new sub-paragraph (a) of Section 
I.(B)(5) of Procedure XV to specifically address Intraday MTM Charges. 
NSCC would make non-substantive cleanup changes to the procedure to 
describe the existing charge and clarify that the charge reflects the 
difference between the most recent NSCC ``marked''-to-market price and 
most recently observed market price of a Member's positions. NSCC would 
also add a new defined term, ``Intraday Mark-to-Market Threshold,'' to 
represent the existing 80 percent threshold for Intraday Mark-to-Market 
Charges.
    In addition, NSCC would remove a clause stating that NSCC may 
reduce the Intraday Mark-to-Market Threshold during volatile market 
conditions ``by accelerating the collection of anticipated additional 
margin from Members whose portfolios may present relatively greater 
risks to [NSCC] on an overnight basis.'' NSCC believes that the revised 
rule text would more accurately reflect the circumstances in which NSCC 
may reduce the threshold because the collection of an Intraday MTM 
Charge would not be limited to addressing risk that may arise on an 
overnight basis but may also be needed to address mark-to-market risk 
exposures on an intraday basis. NSCC would also amend the rules to 
provide examples of market conditions that NSCC may consider with 
respect to reducing the Intraday Mark-to-Market Threshold, which 
include, but are not limited to, the occurrence of large price changes 
in a major benchmark equity index.
    NSCC also proposes to add new rule authority to permit NSCC to 
reduce the Intraday Mark-to-Market Threshold for a given Member if NSCC 
determines it to be necessary to protect itself and its Members in 
response to factors such as market conditions or financial or 
operational capabilities affecting such Member. The proposed rule 
change would effectively allow NSCC to lower the Intraday MTM Threshold 
for individual Members or certain groups of Members to address market 
conditions or financial or operational capabilities specifically 
impacting those Members without requiring NSCC to lower the threshold 
across all Members.
    The proposed change is intended to provide additional clarity and 
transparency in the NSCC Rules concerning how NSCC facilities 
compliance with requirements in the CCAS Margin Rules that each CCA 
have policies and procedures reasonably designed to make intraday 
margin calls, as frequently as circumstances warrant, including when 
risk thresholds specified by NSCC are breached or when products cleared 
or markets served display elevated volatility.\21\
---------------------------------------------------------------------------

    \21\ See 17 CFR 240.17ad-22(e)(6)(ii)(C) and supra note 4.
---------------------------------------------------------------------------

Intraday Volatility Charges
    NSCC proposes clarifying and cleanup changes to the existing 
procedure language concerning the calculation of the Intraday 
Volatility Charge. First, NSCC would create new sub-paragraph (b) of 
Section I.(B)(5) of NSCC Procedure XV to specifically address Intraday 
Volatility Charges. NSCC would make non-substantive cleanup changes to 
the procedure to describe the existing charge. NSCC would also add a 
new defined term, ``Intraday Volatility Threshold,'' to represent the 
100 percent threshold for Intraday Volatility Charges.
    Additionally, NSCC proposes to remove existing rule text stating 
that NSCC would not collect an Intraday Volatility Charge if (a) trades 
submitted later in the day would offset trades submitted earlier in the 
day, such that the thresholds would not have been met if such activity 
had been submitted earlier in the day, or (b) the threshold was met due 
to the submission of an erroneous trade that can be corrected. This 
procedure language would be replaced by the proposed rules discussed 
above, which would provide an enhanced explanation of NSCC's process 
for determining whether to collect an Intraday Margin Charge, which 
includes the aforementioned scenarios for determining whether to 
collect an Intraday Volatility Charge.
    In addition, NSCC would remove a clause stating that NSCC may 
reduce the Intraday Volatility Threshold during volatile market 
conditions or market events that cause increases in trading volumes 
``by accelerating the collection of anticipated additional margin from 
those Members whose portfolios may present relatively larger risks to 
[NSCC] on an overnight basis.'' NSCC believes that the revised rule 
text would more accurately reflect circumstances in which NSCC may 
reduce the threshold because the collection of an Intraday Volatility 
Charge would not be limited to addressing risk that may arise on an 
overnight basis but may also be needed to address volatility risk 
exposures on an intraday basis. NSCC would also amend the rules to 
provide examples of market conditions that NSCC may consider with 
respect reducing the Intraday Volatility Threshold, which include, but 
are not limited to, ETF index rebalancing periods or the occurrence of 
large price changes in a major benchmark equity index.
    NSCC also proposes to add new rule authority to permit NSCC to 
reduce the Intraday Volatility Threshold for a given Member if NSCC 
determines it to be necessary to protect itself and its Members in 
response to factors such as market conditions or financial or 
operational capabilities affecting such Member. The proposed rule 
change would effectively allow NSCC to lower the Intraday Volatility 
Threshold for individual Members or certain groups of Members to 
address market conditions or financial or operational capabilities 
specifically impacting those Members without requiring NSCC to lower 
the threshold across all Members.
    NSCC would also adopt new rules concerning NSCC's authority to 
waive, in exigent circumstances, an Intraday Volatility Charge that it 
may otherwise ordinarily collect. Specifically, the proposed rule 
change would provide that NSCC may waive the collection of an Intraday 
Volatility Charge in exigent circumstances if NSCC determines (i) that 
such a waiver is necessary to protect NSCC, its participants, investors 
and the public interest or (ii) that NSCC can effectively address the 
risk exposure presented by the Member without the collection of such 
charge.
    The proposed change is intended to provide additional clarity and 
transparency in the NSCC Rules concerning how NSCC facilities 
compliance with requirements in the CCAS Margin Rules that each CCA 
have policies and procedures reasonably designed to make intraday 
margin calls, as frequently as circumstances warrant, including when 
risk thresholds specified by NSCC are breached or when products cleared 
or markets served display elevated volatility.\22\

Other Proposed Changes to NSCC Rules
Proposed Clarifications Concerning the Frequency of Clearing Fund 
Calculations
    NSCC proposes to amend the introductory section of NSCC Procedure 
XV to rename the Procedure and provide additional context regarding the 
frequency of NSCC's Clearing Fund calculations. Specifically, the 
proposed rule change would relocate a footnote to the introductory 
section of Procedure XV stating that NSCC performs all Clearing Fund 
calculations daily or on a more frequent basis if NSCC deems it 
appropriate. NSCC also proposes to add additional clarifying language 
to this section noting that times all may be extended as needed by NSCC 
to (i) address operational or other delays that would reasonably 
prevent members or NSCC from meeting the deadline or timeframe, as 
applicable, or (ii) allow NSCC time to operationally exercise its 
existing rights under the NSCC Rules and Procedures. In addition, the 
proposed rules would clarify that all times applicable to NSCC are 
standards and not deadlines; actual processing times may vary slightly, 
as necessary.
Proposed Clarifications Concerning MLA Charge Calculation for Certain 
Equity ETFs
    NSCC also proposes to amend Sections I.(A)(1)(g) and I.(A)(2)(f) of 
NSCC Procedure XV to make certain clarifications regarding the 
calculation of the MLA charge for CNS and Balance Order transactions, 
respectively.\23\ As noted above, one of the primary components of 
NSCC's Clearing Fund calculation is the MLA charge, which applies to a 
Member's Net Unsettled Positions, other than long Net Unsettled 
Positions in Family-Issued Securities. For ETFs with in-kind baskets, 
NSCC runs two separate calculations to compare and determine the 
``impact cost'' of liquidating the ETF. NSCC runs (i) a baseline 
calculation to simulate all the ETF positions being liquidated in the 
secondary market (the ``Baseline Calculation'') with the impact cost 
calculation being at the security level (i.e., the ETF shares) and (ii) 
an alternative calculation (``Create/Redeem Calculation'') to simulate 
the ETF positions being liquidated in the primary market using the 
creation/redemption process.\24\ NSCC then uses the smaller calculated 
impact costs of either the Baseline Calculation or the Create/Redeem 
Calculation for purposes of calculating the MLA charge.
---------------------------------------------------------------------------

    \23\ NSCC notes that the MLA charge is also applied to SFT 
Positions. See NSCC Rule 56, Section 12, supra note 3.
    \24\ The impact costs for the Create/Redeem Calculation are 
calculated by decomposing the ETFs into their underlying securities 
and calculating the impact costs of such underlying securities 
utilizing the equity asset subgroup calculations. See NSCC Procedure 
XV, Sections I.(A)(1)(g) and I.(A)(2)(f), supra note 3.
---------------------------------------------------------------------------

    NSCC proposes to modify Sections I.(A)(1)(g) and I.(A)(2)(f) of 
Procedure XV to clarify that, if certain data inputs needed to 
determine ETF decomposition for the Create/Redeem Calculation are 
unavailable or unreliable, NSCC may use the Baseline Calculation for 
purposes of calculating the MLA charge for ETFs. The proposed rule 
change is intended to address limited scenarios where NSCC may be 
unable to perform both calculations for comparison. In such a scenario, 
NSCC believes it may be appropriate to use the Baseline Calculation to 
determine the impact cost and resulting MLA charge for the ETF(s) in 
question. NSCC is not proposing any changes to the manner in which it 
would calculate the Baseline Calculation or the Create/Redeem 
Calculation or the manner in which NSCC would determine the impact cost 
when both calculations are available and reliable.
Implementation Timeframe
    NSCC expects to implement the proposed rule change by no later than 
December 15, 2025, and would announce the effective date of the 
proposed changes by an Important Notice posted to NSCC's website.
2. Statutory Basis
    NSCC believes that the proposed rule change is consistent with the 
requirements of the Act and the rules and regulations thereunder 
applicable to a registered clearing agency. Specifically, NSCC believes 
that the proposed changes are consistent with Section 17A(b)(3)(F) of 
the Act \25\ and Rule 17ad-22(e)(6) thereunder \26\ for the reasons set 
forth below.
---------------------------------------------------------------------------

    \25\ 15 U.S.C. 78q-1(b)(3)(F).
    \26\ 17 CFR 240.17ad-22(e)(6).
---------------------------------------------------------------------------

    Section 17A(b)(3)(F) of Act \27\ 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 assure the 
safeguarding of securities and funds which are in the custody or 
control of the clearing agency or for which it is responsible and, in 
general, to protect investors and the public interest. The proposed 
rule change would enhance the clarity and transparency of NSCC's Rules 
regarding the ongoing monitoring, calculation and collection of 
Intraday Margin Charges. Specifically, the proposed rule change would 
enhance Procedure XV of the NSCC Rules to more clearly describe how 
NSCC: (i) monitors its intraday mark-to-market and volatility exposures 
each day on an ongoing basis; (ii) makes intraday calls for Intraday 
Margin Charges, as frequently as circumstances warrant, including when 
certain risk thresholds are breached or when the products cleared or 
markets served display elevated volatility; and (iii) determines 
whether to make an Intraday Margin Call and documents when it 
determines to waive, reduce or not make an Intraday Margin Call 
pursuant to its written policies and procedures. The proposed rule 
change would also introduce authority for NSCC to lower its intraday 
margin call thresholds for individual Members or certain groups of 
Members to address market conditions or financial or operational 
capabilities specifically impacting those Members without requiring 
NSCC to lower the threshold across all Members. NSCC believes that 
providing this additional transparency and clarity in the NSCC Rules 
would promote the understanding of NSCC's intraday margin processes by 
NSCC's Members, market participants and the public. This, in turn, 
would help Members understand their potential obligations to NSCC, 
particularly with respect to Intraday Margin Charges, so that they are 
better equipped and able to satisfy such obligations when due. NSCC 
uses the margin and Clearing Fund it collects to mitigate potential 
losses to NSCC (and through loss allocation, to its Members) associated 
with liquidating a defaulting Member's portfolio and to continue to 
effect the prompt and accurate clearance and settlement of securities 
transactions in the event NSCC ceases to act for a Member. As a result, 
NSCC believes the proposed rule change is designed to promote the 
prompt and accurate clearance and settlement of securities 
transactions, to assure the safeguarding of securities and funds which 
are in the custody or control of NSCC or for which it is responsible 
and, in general, to protect investors and the public interest in 
accordance with the requirements of Section 17A(b)(3)(F) of Act.

    The proposed rule change would also provide clarity in the NSCC 
Rules to allow NSCC to use the Baseline Calculation for determining the 
impact costs for certain equity ETFs in the MLA charge when certain 
data inputs required for the Create/Redeem Calculation are not 
available. NSCC believes that using the existing, conservative Baseline 
Calculation for determining the impact costs of

[[Page 17496]]

liquidating certain equity ETFs in such a scenario would appropriately 
address risks presented to NSCC. As noted above, NSCC uses the margin 
and Clearing Fund it collects to mitigate potential losses to NSCC and 
its Members and to continue to effect the prompt and accurate clearance 
and settlement of securities transactions in the event NSCC ceases to 
act for a Member. As a result, NSCC believes the proposed changes are 
designed to promote the prompt and accurate clearance and settlement of 
securities transactions, to assure the safeguarding of securities and 
funds which are in the custody or control of NSCC or for which it is 
responsible and, in general, to protect investors and the public 
interest in accordance with the requirements of Section 17A(b)(3)(F) of 
the Act.
    Exchange Act Rule 17ad-22(e)(6)(ii) \28\ requires that a CCA 
establish, implement, maintain, and enforce written policies and 
procedures reasonably designed to cover its credit exposures to its 
participants by establishing a risk-based margin system that, among 
other things, (i) monitors intraday exposures on an ongoing basis; (ii) 
includes the authority and operational capacity to make intraday margin 
calls, as frequently as circumstances warrant, including the following 
circumstances: (1) when risk thresholds specified by the CCA are 
breached; or (2) when the products cleared or markets served display 
elevated volatility; and (iii) documents when the CCA determines not to 
make an intraday call pursuant to its written policies and procedures. 
The proposed rule change would enhance the clarity and transparency of 
NSCC's Rules regarding the ongoing monitoring, calculation and 
collection of Intraday Margin Charges. Specifically, the proposed rule 
change would enhance Procedure XV of the NSCC Rules to more clearly 
describe how NSCC: (i) monitors its intraday mark-to-market and 
volatility exposures each day on an ongoing basis; (ii) makes intraday 
calls for Intraday Margin Charges, as frequently as circumstances 
warrant, including when certain risk thresholds are breached or when 
the products cleared or markets served display elevated volatility; and 
(iii) determines whether to make an Intraday Margin Call and documents 
when it determines to waive, reduce or not make an Intraday Margin Call 
pursuant to its written policies and procedures. Accordingly, NSCC 
believes the proposed changes to the NSCC Rules are reasonably designed 
to facilitate compliance with the requirements of Exchange Act Rule 
17ad-22(e)(6)(ii).

    \28\ 17 CFR 240.17ad-22(e)(6)(ii).
---------------------------------------------------------------------------

    Exchange Act Rule 17ad-22(e)(6)(i) \29\ requires that a CCA 
establish, implement, maintain, and enforce written policies and 
procedures reasonably designed to establish a risk-based margin system 
that, among other things, considers, and produces margin levels 
commensurate with, the risks and particular attributes of each relevant 
product, portfolio, and market. As discussed above, the proposed rule 
change would also provide clarity in the NSCC Rules to allow NSCC to 
use the Baseline Calculation for determining impact costs for certain 
equity ETFs in the MLA charge when certain data inputs required for the 
Create/Redeem Calculation are not available.\30\ The proposed changes 
would enable NSCC to use its existing, conservative Baseline 
Calculation for determining the impact costs of liquidating certain 
equity ETFs to generate Clearing Fund requirements that appropriately 
address risks presented to NSCC. NSCC believes that these proposed 
changes are reasonably designed to allow NSCC to consider, and produce 
margin levels commensurate with, the risks and particular attributes of 
relevant products, portfolios, and markets in accordance with Exchange 
Act Rule 17ad-22(e)(6)(i).
---------------------------------------------------------------------------

    \29\ 17 CFR 240.17ad-22(e)(6)(i).
    \30\ Rule 17ad-22(e)(6)(iv) under the Act requires each CCA that 
is a central counterparty to establish, implement, maintain and 
enforce written policies and procedures reasonably designed to cover 
its credit exposures to its participants by establishing a risk-
based margin system that, at a minimum, uses reliable sources of 
timely price data and other substantive inputs, and uses procedures 
(and, with respect to price data, sound valuation models) for 
addressing circumstances in which price data or other substantive 
inputs are not readily available or reliable, to ensure that the CCA 
can continue to meet its obligations under Rule 17ad-22(e)(6). Such 
policies and procedures must include either (i) the use of price 
data or substantive inputs from an alternate source; or (ii) if it 
does not use an alternate source, the use of a risk-based margin 
system that does not rely on substantive inputs that are unavailable 
or unreliable. See 17 CFR 240.17ad-22(e)(6)(iv). NSCC has not at 
this time determined the data inputs required for the Create/Redeem 
Calculation to be ``substantive inputs'' for purposes of Rule 17ad-
22(e)(6)(iv); however, NSCC still believes that it is appropriate to 
allow NSCC to use its existing alternative Baseline Calculation for 
the MLA charge, which do not rely on those inputs, if the data 
inputs for the Create/Redeem Calculation are not available.
---------------------------------------------------------------------------

    For the reasons set forth above, NSCC believes the proposed rule 
change is consistent with Section 17A(b)(3)(F) of the Act \31\ and Rule 
17ad-22(e)(6) thereunder.\32\

(B) Clearing Agency's Statement on Burden on Competition

    Section 17A(b)(3)(I) of Act \33\ requires that the rules of a 
clearing agency do not impose any burden on competition not necessary 
or appropriate in furtherance of the purposes of the Act. NSCC does not 
believe the proposed rule change would present any burden or have a 
material impact on competition. The proposed rule change is primarily 
designed to ensure that the NSCC Rules remain transparent, accurate and 
clear, particularly concerning NSCC's existing processes for the 
ongoing monitoring, recalculation and collection of Intraday Margin 
Charges. To the extent that NSCC is introducing new authority in its 
Rules, such as the potential use of the Baseline Calculation for MLA 
charges when the Create/Redeem Calculation is not available or adopting 
authority to lower Intraday Margin Call thresholds for individual 
Members, these Rules would apply equally to all Members and would not 
inhibit access to NSCC's services or favor any particular Member over 
another. With respect to individual Member margin call thresholds, this 
authority would only be utilized in the event that circumstances 
require NSCC to address market conditions or financial or operational 
capabilities specifically impacting unique Members or groups of Members 
and broader market conditions do not warrant lowering the threshold 
across all Members. NSCC believes the proposed change is necessary and 
appropriate to facilitate NSCC's compliance with requirements of the 
Act and the rules and regulations thereunder applicable to a registered 
clearing agency, specifically NSCC's obligations to effectively 
identify, measure, monitor, and manage its credit exposures to 
participants under Rules 17ad-22(e)(4) and (6).\34\ Therefore, NSCC 
does not believe that the proposed rule change would impose any burden 
on competition that is not necessary or appropriate in furtherance of 
the purposes of the Act.
