September 26, 2025.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(``Exchange Act'' or ``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice 
is hereby given that on September 26, 2025, The Options Clearing 
Corporation (``OCC'' or ``Corporation'') filed with the Securities and 
Exchange Commission (``SEC'' or ``Commission'') the proposed rule 
change as described in Items I, II, and III below, which Items have 
been prepared primarily by OCC. The Commission is publishing this 
notice to solicit comments on the proposed rule change from interested

I. Clearing Agency's Statement of the Terms of Substance of the 
Proposed Rule

    Change
    This proposed rule change would allocate Clearing Fund deposit 
requirements in connection with its methodology among its Clearing 
Members to better align the allocation with the sizing of the Clearing 
Fund so that stress based risk is fairly allotted to those market 
participants that expose OCC to such stress risk. Specifically, the 
proposed changes would: (1) modify OCC's allocation weighting formula 
for allocating Clearing Fund Contribution requirements by introducing a 
70% Clearing Fund risk-based shortfall allocation based on stress loss 
in excess of margin (the ``shortfall''); changing the weighting 
percentages by reducing the margin allocation from 70% to 15%; removing 
the open interest component; extending the lookback period from 1-month 
to 3-months of data to align with the Clearing Fund size lookback; and 
reflect a new weighting scheme of 70% shortfall, 15% margin, and 15% 
cleared volume; (2) provide authority in the rules for OCC to hold 
constant allocation weights month-over-month in light of volatile 
market conditions; and (3) make other minor clarifying and conforming 
changes to the Clearing Fund Methodology Policy (``Policy''), and 
Comprehensive Stress Testing & Clearing Fund Methodology, and Liquidity 
Risk Management Description (``Methodology Description'').
    Proposed changes to the OCC Rules are filed as Exhibit 5A to File 
Number SR-OCC-2025-018. Proposed changes to the Methodology Description 
are filed as confidential Exhibit 5B to File Number SR-OCC-2025-018. 
Proposed changes to the Policy are filed as confidential Exhibit 5C to

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

    In its filing with the Commission, OCC 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. OCC has prepared summaries, set forth in sections (A), 
(B), and (C) below, of the most significant aspects of these 
statements.

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

    OCC is the sole clearing agency for standardized equity options 
listed on national securities exchanges registered with the Commission. 
OCC also clears certain stock loan and futures transactions. In its 
role as a clearing agency, OCC is the guarantor for all contracts 
cleared through OCC; that is, OCC becomes the buyer to every seller and 
the seller to every buyer (or the lender to every borrower and the 
borrower to every lender, in the case of stock loan transactions). As a 
central counterparty (``CCP''), OCC is exposed to certain risks because 
OCC is obligated to perform pursuant to its By-Laws and Rules even when 
one of its members defaults, including credit risk, which is the risk 
that OCC would not maintain sufficient financial resources to cover 
exposures.
    OCC manages its credit risk through various safeguards to ensure 
that it has sufficient financial resources in the event of a Clearing 
Member failure. For example, OCC periodically collects margin 
collateral from its Clearing Members, which is designed to cover the 
credit exposures they individually present to OCC with a high degree of 
confidence. In order to ensure that OCC maintains sufficient qualifying 
liquid resources to manage its liquidity risk, and to address the tail 
risk that the margin collateral it collects from each Clearing Member 
might be insufficient to cover OCC's credit exposure to a defaulting 
member, OCC also maintains a Clearing Fund, which is a mutualized pool 
of financial resources to which each Clearing Member is required to 
contribute. OCC may borrow against or charge losses to the Clearing 
Fund under circumstances set forth in OCC's rules, including when 
managing a default of a Clearing Member. Subject to OCC's rules, non-
defaulting Clearing Members would be obligated to replenish the 
Clearing Fund if OCC

[[Page 47384]]

were to charge a loss to the Clearing Fund.
    OCC rules also provide for how the Clearing Fund is sized and 
allocated amongst OCC's membership. With respect to sizing, OCC's rules 
require OCC to size the Clearing Fund monthly based on stress test 
scenarios that present extreme but plausible market conditions in order 
to ensure that: (i) OCC has sufficient pre-funded financial resources 
to withstand a default of the two Clearing Member Groups that would 
potentially cause the largest aggregate credit exposure in such 
conditions; \4\ and (ii) OCC has sufficient liquid resources to settle 
payment obligations under a wide range of foreseeable stress scenarios 
that include the default of the Clearing Member Group that would 
generate the largest aggregate payment obligation in such 
conditions.\5\ However, the current allocation methodology does not 
include a component that takes into account the same stressed losses 
used to size the fund when determining each Clearing Member's required 
Clearing Fund deposit and creates inconsistency between the sizing and 
allocation across the membership. By including such a component in the 
allocation methodology OCC could distribute individual Clearing Fund 
requirements based on the directional stressed risk that Clearing 
Members present to OCC.
---------------------------------------------------------------------------

    \4\ See OCC Rule 1001(a).
    \5\ See, e.g., Exchange Act Release No. 89014 (June 4, 2020), 85 
FR 35446 (June 10, 2020) (SR-OCC-2020-003) (approving OCC's 
Liquidity Risk Management Framework).
---------------------------------------------------------------------------

    OCC proposes to modify this allocation methodology to align more 
closely with the methodology for sizing the Clearing Fund. The new 
methodology would primarily be driven by a Clearing Member's 
proportionate share of shortfalls (i.e., the estimated stress loss 
exposure in excess of margin requirements) and would be more aligned 
with the current sizing methodology because the same stressed scenarios 
used for sizing would be used to calculate the shortfalls. By aligning 
the allocation methodology with the stressed scenarios, the proposed 
allocation methodology would charge each Clearing Member more in 
proportion to the stress loss risk that its trading activity presents 
to OCC. As such, the new methodology would focus more on the risk that 
a Clearing Member introduces to OCC through stress scenarios, rather 
than the risk that OCC already collateralizes through collection of 
margin requirements.
    The proposed rule change would also provide for an alternate 
allocation method for stressed market conditions in which shortfall may 
no longer be a reliable factor in allocating the Clearing Fund. OCC has 
observed that shortfalls generally decrease during periods of 
heightened volatility when margin coverage increases. In order to avoid 
significant changes to the Clearing Fund allocation month-over-month, 
the shortfall, total risk, and volume calculations would be performed 
using a three-month lookback. However, in the unlikely event that 
shortfalls decrease over a longer period of time due to a prolonged 
period of heightened volatility, OCC proposes to establish authority to 
hold constant the allocation from month-to-month as well as remove the 
hold constant provision until heightened market volatility conditions 
abate.
    The impact to each Clearing Member's allocation under the proposed 
methodology would be dependent on the trading activity of that Clearing 
Member and based on their end-of-day positions. While the changes would 
not affect the overall size of the Clearing Fund, some Clearing Members 
would see their allocation increase while others would see their 
allocation decrease. The impact to Clearing Member allocations will be 
primarily driven by the directionality of their portfolios and the 
resulting stress exposures relative to other Clearing Members given the 
change is intended to incorporate a component of the allocation based 
on their share of such stress exposure. Clearing Members that have 
alignment in terms of direction across accounts or exposure to 
positions that are more reactive to stress scenarios, or a combination 
of both, will likely see increases. However, OCC believes that such 
increases or decreases would be commensurate with the stressed risk 
presented to OCC by each individual Clearing Member.
1. Purpose
Background
Stressed Losses and the Clearing Fund Sizing Methodology
    Under the Policy, OCC determines the size of its Clearing Fund 
based on the output of stress tests conducted using a range of 
foreseeable scenarios that utilize standard pre-determined parameters 
and assumptions. These stress tests are conducted daily and consider a 
range of stress scenarios with possible price changes that include: (1) 
relevant peak historic price volatilities; (2) shifts in other market 
factors including, as appropriate, priced determinants and yield 
curves; (3) the default of one or multiple members; (4) forward-looking 
stress scenarios.
    As described in the Methodology Description, OCC leverages a suite 
of sizing stress tests broadly categorized into two types: ``Systemic 
Scenarios'' and ``Idiosyncratic Scenarios.'' Systemic Scenarios are 
created to capture risk to OCC in an extreme event impacting all 
positions mainly driven by risk drivers, while Idiosyncratic Scenarios 
are used to assess the impact of extreme moves of specific equities in 
a Clearing Member portfolio.
    Systemic Scenarios include certain ``Hypothetical Scenarios'' that 
represent events in which market conditions change in ways that have 
not yet been observed. The Hypothetical Scenarios are derived using 
statistical methods (e.g., draws from estimated multivariate 
distributions) or created based on expert judgment (e.g., a 15% decline 
in market prices and 50% increase in volatility). These scenarios give 
OCC the ability to change the distribution and level of stress in ways 
necessary to produce an effective forward-looking stress testing 
methodology. OCC uses these pre-determined stress scenarios in stress 
tests, conducted daily, to determine OCC's risk exposure to each 
Clearing Member Group by simulating the profits and losses of the 
positions in their respective account portfolios under each such stress 
scenario. Idiosyncratic Scenarios are designed to capture the risks of 
extreme moves in individual or small subsets of securities. OCC shocks 
each single-name equity and evaluates the effects of such shocks on 
every Clearing Member Group portfolio, within which OCC identifies the 
four single-name equities for which such shocks would result in the 
largest losses.
    From the combined set of scenarios used in the determination of the 
Clearing Fund size (``Sizing Scenarios''), which currently consist of 
Systemic and Idiosyncratic Scenarios, OCC selects the largest aggregate 
stress test exposures as the primary basis for sizing the Clearing 
Fund. Under the Policy and Methodology Description, OCC performs these 
stress test scenarios to establish the monthly size of the Clearing 
Fund necessary for OCC to maintain sufficient pre-funded financial 
resources to cover losses that could arise from the default of the two 
Clearing Member Groups that would potentially cause the largest 
aggregate credit exposure in extreme but plausible market conditions as 
a result of a 1-in-80 year hypothetical market event.

[[Page 47385]]

Clearing Fund Allocation Methodology
    Currently, OCC's rules provide that Clearing Members are required 
to make Clearing Fund deposits comprised of a fixed amount of $500,000 
per Clearing Member and an amount that is a Clearing Member's 
proportionate share of the remaining amount necessary to arrive at the 
total size of the Clearing Fund (``variable amount'') determined by a 
weighted average of the Clearing Member's proportionate share of three 
other measures:
    (1) total risk: a risk measure aggregated across all accounts of a 
Clearing Member over the previous month determined using OCC's margin 
methodology and such add-on charges as may be determined pursuant to 
OCC's policies and procedures;
    (2) open interest: the daily average number of open interest in 
cleared contracts and stock loan and borrow positions during the 
previous calendar month; and
    (3) volume: the daily average number of all cleared contracts and 
stock loan and borrow positions cleared by such Clearing Member during 
a look-back period determined by OCC from time to time.\6\
---------------------------------------------------------------------------

    \6\ See OCC Rule 1003(b)(iii).
---------------------------------------------------------------------------

    Each Clearing Member's proportionate share of the variable amount 
is determined using an allocation formula that apportions 70% from 
total risk, 15% from volume, and 15% from open interest. Each Clearing 
Member's margin requirement is calculated from all accounts held by the 
Clearing Member.
Proposed Changes
    OCC proposes to enhance its Clearing Fund allocation strategy by: 
(1) modifying OCC's allocation weighting formula; (2) providing 
authority in the rules for OCC to hold constant month-over-month 
allocation weights in light of volatile market conditions; and (3) 
other minor clarifying and conforming changes to the Methodology 
Description and Policy.
1. Modification of OCC's Allocation Weighting Methodology
    OCC proposes to modify its methodology for allocating Clearing Fund 
requirements amongst its Clearing Members to focus on the stress loss 
in excess of margin (i.e., ``shortfall''). OCC believes it is 
appropriate to use the shortfall generated from running stress 
scenarios as a basis to calculate the Clearing Fund allocations because 
shortfall is a closer proxy to the risk borne by OCC from Clearing 
Members assuming a default in stressed market conditions, which are the 
conditions that the Clearing Fund is designed to address. Accordingly, 
OCC proposes to define ``shortfall'' under Rule 1003(b)(ii) to mean 
``an estimated stress loss exposure in excess of margin amounts 
aggregated across all accounts of a Clearing Member determined using 
the Corporation's margin methodology and such add-on charges as may be 
determined pursuant to the Corporation's policies and procedures.'' \7\ 
The Methodology Description would, in turn, provide that the Clearing 
Fund shortfall would be calculated and allocated from Sizing Scenarios 
(i.e., the 1-in-80 Rally, 1-in-80 Decline and Idiosyncratic Sizing 
scenarios).\8\ OCC believes this approach better aligns the allocation 
of the Clearing Fund with the sizing of the Clearing Fund. OCC also 
proposes to make conforming changes to its Policy and Methodology 
Description to reflect the new definition of ``shortfall.''
---------------------------------------------------------------------------

    \7\ The shortfall component used in the allocation is based on 
the highest shortfall across all Sizing scenarios for that Clearing 
Member on a given business date and will be treated as zero in the 
even there are no shortfalls.
    \8\ In the event the size of the Clearing Fund was a result of 
the Sufficiency Buffer, shortfalls from Sufficiency scenarios would 
be considered as part of the Sizing Scenarios for the Clearing 
Member(s) within the Clearing Member Group(s) that triggered the 
sizing condition. The term ``Sufficiency Buffer'' is the condition 
that occurs if the results of a daily Sufficiency Stress Test over 
the final five business days preceding the monthly Clearing Fund 
sizing exceed 90% of the projected Clearing Fund size for the 
upcoming month, the Clearing Fund size shall be set such that the 
peak Sufficiency Stress Test shortfall is no greater than 90% of the 
Clearing Fund size.
---------------------------------------------------------------------------

    The new shortfall definition in Rule 1003(b)(ii) would replace the 
definition of ``open interest,'' which OCC would remove as an input to 
the allocation formula. OCC believes that removing the open interest 
component is consistent with the aim of making the allocation 
methodology more risk based. For the same reason, OCC previously 
reduced the weighting given to open interest in the allocation formula 
from 100% to 50%,\9\ and then from 50% to 15%.\10\ In each case, OCC 
determined that the change was appropriate to align the allocation 
methodology with the risks posed to OCC and the Commission found the 
proposed changes to be consistent with the Exchange Act.\11\
---------------------------------------------------------------------------

    \9\ See Exchange Act Release No. 69403 (Apr. 18, 2013), 78 FR 
24257 (Apr. 24, 2013) (SR-OCC-2013-02).
    \10\ See Exchange Act Release No. 83735 (July 27, 2018), 83 FR 
37855, 37859 (Aug. 2, 2018) (SR-OCC-2018-008).
    \11\ See id. at 37863 (concluding that the change would ``allow 
OCC to better manage its credit exposures to its clearing members by 
better aligning each clearing member's contributions to the credit 
risk it poses to OCC''); Exchange Act Release No. 69403, 78 FR at 
24258 (concluding that the change would ``enhanc[e] the Clearing 
Fund allocation methodology by incorporating measures that OCC 
believes will apportion contributions based on more sophisticated 
measurements of Clearing Members' usage of OCC's facilities and 
recognize demands on OCC's services and facilities that are not 
captured by the current methodology'').
---------------------------------------------------------------------------

    Under proposed amendments to Rule 1003(b), the new shortfall factor 
would receive a 70% weighting in calculating a Clearing Member's 
proportionate share of the variable amount. OCC also proposes to change 
the weighting formula to allocate the remaining weight of 30%. Total 
risk, which would be re-titled ``margin'' for clarity,\12\ would remain 
a factor in the allocation, but would be reduced to 15%. OCC believes 
that maintaining the margin component is appropriate as margin 
evaluates risk using a different monte carlo based model and therefore 
can capture a different risk profile from stress testing. This reflects 
a decrease from OCC's current 70% allocation weighting for the margin 
component of a Clearing Member's Clearing Fund allocation. OCC believes 
that reducing the allocation to this level would be consistent with the 
aim of aligning the allocation of the Clearing Fund with the sizing of 
the Clearing Fund. OCC also proposes to keep the cleared volume 
allocation at the 15% threshold, which is not changed from OCC's 
current allocation methodology. OCC believes that maintaining the 
volume threshold at the same level would be appropriate to ensure that 
Clearing Member participants with intra-day trading activities receive 
an allocation of the Clearing Fund even when their holdings overnight 
reflect flat positions.\13\ The proposed allocation methodology would 
result in a formula that distributes Clearing member contributions 
according to the following proportions: 70% shortfall, 15% margin, and 
15% cleared volume. OCC believes, based on its analysis of different 
allocation weightings,\14\ that this specific allocation scheme 
generates a balance between the various risks captured by each 
component and would align the Clearing Fund allocation with the 
exposure driving the size of the Clearing Fund. The proposed allocation 
scheme creates alignment between the process to size the Clearing Fund 
and the process to allocate the Clearing Fund, as

[[Page 47386]]

the same set of stress scenarios used to calculate the shortfalls will 
be used as input to the allocation scheme. Margin evaluates risk based 
on a different model than stress testing and therefore can capture 
different risk profiles than shortfall. Volume keeps in place a means 
to allocate a portion of the Clearing Fund based on trading activity 
that occurs throughout the day, which shortfall and margin do not 
currently capture as they utilize data as of EOD.
---------------------------------------------------------------------------

    \12\ Specifically, using the term ``margin'' rather than ``total 
risk'' provides better clarity as to the metric upon which the 
factor is based.
    \13\ Overnight positions maybe flat for certain Clearing Member 
participants because holdings in their portfolio may net to zero 
from intra-day trading activities i.e., entering, existing, or 
transferring trades during the day.
    \14\ OCC has included the results of this analysis in 
confidential Exhibit 3 to File No. SR-OCC-2025-018.
---------------------------------------------------------------------------

    OCC also proposes to adopt a longer lookback period for all three 
measures, from a one-month lookback for the current total risk measure 
to a three-month lookback for shortfall, margin and cleared volume. A 
three-month lookback aligns with the parameters used in the sizing of 
the Clearing Fund and mitigates the impact of significant changes in 
margin shortfalls driven by periods of elevated margin coverage. 
Accordingly, OCC proposes to replace the lookback periods in the 
definitions section under Rules 1003(b)(i), (ii) and (iii) to three (3) 
calendar months. OCC also proposes to make conforming changes to 
reflect this change in its Policy and Methodology Description.
    With respect to the impact of the proposal on the Clearing Fund 
allocations, OCC has reviewed the potential impact of the proposal on 
Clearing Fund allocations, for the period between May 2024 and May 2025 
and also for April 2020, a time horizon that reflected a monthly 
resizing during a stressed market period.\15\ OCC has observed that 
overall, the proposed approach allocates the Clearing Fund in a more 
distributed fashion within the top 10 Clearing Members (as measured by 
highest Clearing Fund contribution amounts) with some members 
experiencing larger changes relative to other Clearing Members, but, as 
noted above, the effects of the proposal would be primarily attributed 
to the directionality of Clearing Member portfolios and the resulting 
stress exposures. As a result, some Clearing Members will see their 
Clearing Fund requirement increase, while others will see it decrease 
with significant and pronounced variations across members. Generally, 
Clearing Members that have aligned directional exposure across accounts 
or exposure to positions that are more sensitive to stress events, or a 
combination of both, could see an increase from this proposal but it is 
portfolio-dependent and also a function of how the Clearing Members 
compare to other Clearing Members. The impact of the proposal on OCC's 
top 5, top 10, and remaining Clearing Members over the past four 
quarters spanning third quarter 2024 through second quarter 2025,\16\ 
shown as averages, is presented in the tables below:

Clearing Fund contributions, while the top 5 Clearing Members would 
have seen a 2.67% decrease in Clearing Fund contributions over the four 
quarters referenced. In contrast, in Table 3, which presents the 
effects on the remaining members, excluding the top 10 Clearing Fund 
contributors, OCC observed a 1.28% decrease in contributions to the 
Clearing Fund, indicating that the proposed rule change would have 
allocated a greater portion of the Clearing Fund contribution 
requirement toward the larger, top 10

[[Page 47387]]

contributing members. However, OCC has also observed that there were 
substantial variations in the range and distribution of relative change 
between individual contributions spread across members within each 
category.\17\
---------------------------------------------------------------------------

    \17\ This applies to members within all three categories 
presented in Table 1,2, and 3.
---------------------------------------------------------------------------

2. Authority to Hold Constant Allocation Weights
    OCC proposes to expand its authority under the Rules to hold 
constant month-over-month Clearing Member allocations during stressed 
market conditions. When markets are highly volatile during periods of 
market stress, elevated margin coverage becomes more commonplace and 
consequently may reduce or even eliminate Clearing Fund shortfalls 
because of elevated margin requirements. Such reductions in shortfalls 
could cause the resulting Clearing Fund allocation to change 
dramatically month-over month. In the first instance, OCC would address 
this risk through the three-month lookback discussed above, which would 
help to smooth month-over-month changes.\18\ Based on its analysis of 
the potential impact of the current proposal, OCC believes that the 
proposed three-month lookback would have been sufficient without 
further intervention in recent periods of elevated stress, for example 
as observed in March 2020.\19\ However, in the unlikely event that high 
volatility and reduced shortfalls persisted, OCC believes it is 
possible the extended lookback alone may not be sufficient even though 
that has not been observed in the impact data produced. As a result, 
the proposed rules include authority for OCC to hold all Clearing 
Members' proportionate shares of the variable amount constant month-
over-month.\20\
---------------------------------------------------------------------------

    \18\ OCC proposes to extend the lookback from one to three 
months to smooth out the effects of high volatility during periods 
when elevated margin coverage may reduce or even eliminate 
shortfalls. Using a one-month lookback during such periods can cause 
Clearing Fund allocations to fluctuate dramatically month-over-
month.
    \19\ See supra note 14.
    \20\ For the avoidance of doubt, the variable amount, which is 
dependent on the size of the Clearing Fund, would not be held 
constant under this authority. Rather, OCC would hold constant the 
proportionate allocation of the variable amount across the 
membership.
---------------------------------------------------------------------------

    Specifically, proposed Rule 1003(c) would provide that OCC, at its 
sole discretion, may elect to hold constant month-over-month Clearing 
Members' proportionate shares calculated under Rule 1003(b) and the 
Corporation's policies and procedures. Rule 1003(c) would further 
provide that any such election would (i) be based upon then-existing 
facts and circumstances, (ii) be in furtherance of the integrity of OCC 
and the stability of the financial system, and (iii) take into 
consideration the legitimate interests of Clearing Members and market 
participants. OCC believes this authority is consistent with its 
existing authority to temporarily increase the Clearing Fund size \21\ 
and the Clearing Fund Cash Requirement.\22\
---------------------------------------------------------------------------

    \21\ See OCC Rule 1001(d).
    \22\ See OCC Rule 1002(a)(i)(A).
---------------------------------------------------------------------------

    Proposed amendments to the Policy would provide that OCC would 
exercise this authority by conducting daily risk analysis to monitor 
the results of the Cover 2 \23\ Sizing Stress Tests and escalate to the 
Chair of the Stress Testing Working Group (``STWG''),\24\ or the Chief 
Financial Risk Officer, that an STWG meeting be convened to review and 
approve or reject a recommendation to hold constant month-over-month 
the proportionate share of the variable amount of the Clearing Fund for 
all firms. The Policy would be revised to state that any recommendation 
to hold allocations constant would be supported by an analysis of the 
impact to stress exposures from margin coverages changes and the 
resulting Clearing Fund allocation projections.\25\ OCC believes the 
STWG is the appropriate OCC internal governing body to approve or 
reject such recommendation given the authority the Management Committee 
has delegated to it as the subject matter expert on OCC's financial 
risk and liquidity risk stress-testing scenarios, models, underlying 
parameters and assumptions, and stress test results. In addition, OCC 
proposes to append ``Monthly'' to the section heading that deals with 
allocations to read as ``Allocation of Monthly Clearing Fund 
Contributions'' and reflect within the section the authority to hold 
constant month-over-month the allocation proportions or revert to the 
proposed allocation calculation formula, by inserting a new paragraph 
stating ``[s]ubject to the prior approval of the STWG on recommendation 
from STLRM, OCC may hold the proportionate share of the variable amount 
constant month-over-month or revert to the proportionate approach, 
described in Rule 1003.'' Lastly, within the same section a new 
separate paragraph will be inserted that states that ``[t]he Risk 
Committee and Clearing Members shall be notified immediately of any 
determination to hold constant allocations or the reversion to the 
proportionate approach, described in Rule 1003. Such determination and 
the reasons thereof shall be promptly reported to the SEC and the 
CFTC.''
---------------------------------------------------------------------------

    \23\ The term ``Cover 2'' refers to sufficient Pre-Funded 
Financial Resources, at a minimum, to enable OCC to cover a wide 
range of foreseeable stress scenarios that include, but are not 
limited to, the default of the two Clearing Member Groups that would 
potentially cause the largest aggregate credit exposure in extreme 
but plausible market conditions.
    \24\ The STWG is a cross-functional group comprised of 
representatives from relevant OCC business units, including Stress 
Test and Liquidity Risk Management, Credit Risk Management, and 
Model Risk Management.
    \25\ The analysis may include additional information such as the 
percentage of firms generating shortfalls, the size of peak 
shortfalls relative to the Clearing Fund size, a comparison of 
Clearing Fund allocation projections versus current requirements as 
well as a breakdown of the allocation projections by component.
---------------------------------------------------------------------------

Other Clarifying and Conforming Changes
    Finally, OCC proposes several additional clarifying and conforming 
changes to the Rules, Policy, and Methodology Description to align with 
the proposed changes to the Clearing Fund methodology. These supporting 
changes are described below.
Proposed Changes to the Allocation of Clearing Fund Contributions 
Description
    OCC proposes a number of changes to its Methodology Description to 
reflect the proposed changes and describe the proposed allocation 
formula. For example, the Methodology Description would be revised to 
reflect the updated Rule 1003 text changes, which includes introduction 
of the shortfall, removal of the open interest, the extension of the 
lookback period to three months, and incorporation of the new proposed 
weightings for the Clearing Fund Allocation formula. In addition, the 
proposed changes would add a paragraph reflecting the proposed Rule 
1003(c) text. In addition, certain definitions within the Methodology 
Description referring to the OCC's current Clearing Fund allocation, 
including ``daily averages,'' ``Risk Exposure,'' and ``Open Interest'' 
will be removed. Additional clarifying text such as ``Cleared'' will 
also be appended before ``Volume'' to ensure greater clarity regarding 
the definition of ``Cleared Volume.''
Proposed Changes to the Policy
    OCC proposes a number of changes to its Policy to reflect the 
proposed changes. First, all references to ``Draw'' or ``Draws'' in the 
document will be replaced with ``shortfall'' or ``shortfalls,'' 
respectively. In a similar fashion to the Methodology Description, the 
Policy will be revised to reflect the updated Rule 1003 text changes, 
that includes introduction of the ``shortfall,'' removal of the ``open 
interest,'' update to the lookback period to three months,

[[Page 47388]]

and incorporation of the new proposed weightings for the Clearing Fund 
Allocation formula. In addition, the proposed changes would add a 
paragraph reflecting the proposed Rule 1003(c) text.
Proposed Changes to the Rules
    To enhance clarity and eliminate potential confusion, OCC proposes 
to remove all references to an implementation period from Rule 1003. 
Specifically, OCC proposes to delete Interpretation and Policy .03 of 
Rule 1003 in its entirety from OCC's Rules, as this section contains 
the implementation period provisions that are no longer necessary.
Clearing Member Outreach
    OCC has provided an overview of the proposed changes to the 
Financial Risk Advisory Council (``FRAC''), informing Clearing Members 
of the proposed changes. The FRAC is a working group comprised of 
exchanges, Clearing Members, and indirect participants of OCC. OCC has 
not received any material objections or concerns in response to this 
outreach to date.
Implementation Timing
    OCC will implement the proposed changes within 180 days after the 
date OCC receives all necessary regulatory approvals for the proposed 
changes. OCC will announce the implementation date of the proposed 
changes by posting an Information Memorandum on its public website at 
least two (2) weeks prior to implementation.
2. Statutory Basis
    OCC believes the proposed rule change is consistent with the 
requirements of Section 17A(b)(3)(F) of the Exchange Act,\26\ and Rule 
17ad-22(e)(4) \27\ and Rule 17ad-22(e)(2) \28\ thereunder.
---------------------------------------------------------------------------

    \26\ 15 U.S.C. 78q-1(b)(3)(F)
    \27\ 17 CFR 240.17ad-22(e)(4).
    \28\ 17 CFR 240.17ad-22(e)(2).
---------------------------------------------------------------------------

    Section 17A(b)(3)(F) of the Act \29\ requires, among other things, 
that the rules of a clearing agency be designed to promote the prompt 
and accurate clearance and settlement of securities and derivatives 
transactions, to assure the safeguarding of securities and funds which 
are in its custody or control, and in general, to protect investors and 
the public interest. Taken together, OCC believes the proposed changes 
are designed to enhance OCC's overall framework for managing credit and 
liquidity risks and are consistent and in accordance with Section 
17A(b)(3)(F) of the Act \30\ for the reasons set forth below.
---------------------------------------------------------------------------

    \29\ 15 U.S.C. 78q-1(b)(3)(F).
    \30\ Id.
---------------------------------------------------------------------------

    OCC's mutualized Clearing Fund is designed, in part, to cover 
default losses arising from Clearing Member defaults during stressed 
market conditions. As described above, the proposed rule change would 
enhance OCC's framework for managing its credit risk by revising the 
Clearing Fund allocation scheme to include a shortfall component that 
represents the aggregate stress losses in excess of margin. In a 
Clearing Member default, a Clearing Member's Clearing Fund contribution 
would be the first to be utilized to cover any losses before any other 
mutualized resource. The use of shortfall in the allocation scheme 
aligns OCC's credit exposure to that Clearing Member by ensuring its 
Clearing Fund requirements are commensurate with the risk presented to 
OCC, thereby helping to ensure that OCC can continue to effect the 
prompt and accurate clearance and settlement of securities and 
derivatives transactions. The proposed changes to the component 
allocation weights in its Clearing Fund allocation scheme produces 
Clearing Member allocations better aligned with the same stress 
scenarios used to size the Clearing Fund, which OCC believes is 
reasonably designed to enhance OCC's framework for managing credit risk 
because it would result in more proportionate and accountable Clearing 
Fund allocations and generate contribution requirements that are 
commensurate to the risks borne by OCC from its Clearing Members. OCC 
believes these changes would help to reduce risky behavior that may 
arise through risk mutualization and incentivize participants to better 
manage their risk by charging more to Clearing Members who introduce 
such stressed risk, thereby supporting the public interest. In 
addition, OCC would use the Clearing Fund deposit along with the margin 
of a defaulting Clearing Member to manage a default ahead of other 
resources under OCC's default waterfall, including the Clearing Fund 
deposits of non-defaulting Clearing Members.\31\ By allocating more to 
a Clearing Member that is introducing higher stressed risk, more 
resources ahead of risk mutualization would be available in the event 
of that Clearing Member's default, thereby helping to safeguard the 
Clearing Fund deposits of non-defaulting Clearing Members. OCC 
therefore believes these changes are designed to promote the prompt and 
accurate clearance and settlement of securities and derivatives 
transactions, assure the safeguarding of securities and funds which are 
in its custody or control and, in general, protect investors and the 
public interest consistent with Section 17A(b)(3)(F) of the Act.\32\
---------------------------------------------------------------------------

    \31\ See OCC Rule 1006(b).
    \32\ 15 U.S.C. 78q-1(b)(3)(F).
---------------------------------------------------------------------------

    OCC also believes the proposed revisions to its Rules, Policy, and 
Methodology Description to update the lookback period to three months 
for all components of the Clearing Fund allocation scheme and to allow 
OCC to hold constant the allocations month-over-month are designed, in 
general, to protect investors and the public interest. The proposed 
changes are anti-procyclical measures for periods of elevated market 
volatility during which Clearing Members may maintain higher margin 
levels that may cause shortfalls for the majority of market 
participants to fall to zero. The extended lookback and authority under 
Rule 1003(c) would help ensure that OCC's Clearing Fund allocations 
would be smoother month-over-month ensuring that significant 
fluctuations in Clearing Fund allocations are avoided, particularly 
during periods of stressed market conditions in which Clearing Members 
may maintain elevated margin coverage levels and their ability to meet 
additional liquidity demands may be strained. A three-month lookback 
would smooth out the impact to Clearing Members of high volatility 
periods reducing the dramatic fluctuations experienced from using a 
shorter 1-month lookback. As such, OCC believes that these changes 
reduce systemic risk, and are thereby designed to help ensure OCC can 
continue to provide prompt and accurate clearance and settlement of 
securities and derivatives transactions, and in general protect 
investors and the public interest consistent with Section 17A(b)(3)(F) 
of the Act.\33\
---------------------------------------------------------------------------

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

    OCC also believes the proposed changes are consistent with Rules 
17ad-22(e)(4),\34\ which requires that a covered clearing agency 
establish, implement, maintain, and enforce written policies and 
procedures reasonably designed to effectively identify, measure, 
monitor, and manage its credit exposures to participants and those 
arising from its payment, clearing, and settlement processes including 
by, in part, maintaining financial resources at the minimum to enable 
it to cover a wide range of foreseeable stress scenarios that include, 
but are not limited to, the default of the participant family that 
would potentially cause the largest aggregate credit exposure for the 
covered clearing agency in extreme but

[[Page 47389]]

plausible market conditions,\35\ and do so exclusive of assessments for 
additional guaranty fund contributions or other resources that are not 
prefunded.\36\ OCC complies with these obligations by maintaining a 
prefunded Clearing Fund that is sized to cover potential losses 
resulting from the default of its two largest Clearing Member Groups in 
stressed market conditions. With respect to the use of Clearing Funds 
and adherence to the requirements of Rule 17ad-22(e)(4),\37\ the 
Commission has noted that, to the extent that a clearing agency uses 
guaranty or clearing fund contributions to mutualize risk across 
participants, clearing agencies generally should value margin and 
guaranty fund contributions so that the contributions are commensurate 
to the risks posed by the participants' activities.\38\ OCC believes 
that by utilizing the same stressed scenarios used to size the Clearing 
Fund, the proposed allocation methodology would provide for Clearing 
Fund contribution requirements commensurate to the risks posed by each 
Clearing Member. As a result, OCC believes the proposed changes are 
reasonably designed to comply with the requirements of Rule 17ad-
22(e)(4).\39\

Clearing Agencies'').
    \39\ 17 CFR 240.17ad-22(e)(4).
---------------------------------------------------------------------------

    Finally, OCC believes the proposed changes are consistent with Rule 
17ad-22(e)(2)(i),\40\ which requires that each covered clearing agency 
establish, implement, maintain and enforce written policies and 
procedures reasonably designed to provide for governance arrangements 
that, in relevant part, are clear and transparent. As discussed above, 
OCC believes that by establishing authority to hold allocations 
constant month-over-month in extraordinary circumstances in its rules, 
and making clarifying, organizational, and streamlining changes 
elsewhere in its policies and procedures, it would improve the clarity 
of its rules and policies and therefore the proposed changes would be 
consistent with Rule 17ad-22(e)(2)(i).\41\

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

    Section 17A(b)(3)(I) of the Act \42\ requires that the rules of a 
clearing agency not impose any burden on competition not necessary or 
appropriate in furtherance of the purposes of the Act. While the 
proposed rule change may impact Clearing Members to a greater or lesser 
degree depending on each Clearing Member's trading activity, OCC does 
not believe that the proposed rule change would impose any burden of 
competition not necessary or appropriate in furtherance of the purposes 
of the Exchange Act.
---------------------------------------------------------------------------

    \42\ 15 U.S.C. 78q-1(b)(3)(I).
---------------------------------------------------------------------------

    The proposed changes relate to risk management modifications 
designed to shift the allocation from margin to stress shortfall. As 
discussed above, the current Clearing Fund distribution scheme utilizes 
margin as the main driver to allocate individual Clearing Member 
contributions, which may not adequately reflect the risk presented by 
individual Clearing Members in a default in stressed market conditions. 
In such scenarios, OCC believes that the shortfall is a closer proxy to 
the risk borne by OCC to be used as a basis to calculate Clearing Fund 
allocations, notwithstanding that margin and volume would remain 
factors with smaller weightings. The proposed changes would ensure 
contribution requirements would be apportioned to Clearing Members 
based on each Clearing Member's share of the overall shortfall relative 
to margin. Moreover, the proposed rule change would be applied 
uniformly to all Clearing Members, but as noted above, the sizing of 
the Clearing Fund would not be affected. In addition, as indicated by 
OCC's impact analysis, the proposal's effects vary across all members 
under both normal and stressed market conditions. As shown above in 
Tables 1, 2, and 3, some Clearing Members would see their Clearing Fund 
requirement increase, while others will see it decrease. Individual 
impacts would depend on a variety of factors, including but not limited 
to, the directionality of exposure across accounts within a Clearing 
Member, exposure to positions that are more sensitive to stress 
scenarios, and stress exposures relative to other Clearing Members.
    OCC believes these changes are necessary and appropriate requiring 
those Clearing Members that present elevated levels of stress-based 
risk to contribute more to the Clearing Fund and thereby incentivize 
those firms to better manage and reduce the risk attributed to their 
trading activities. Accordingly, OCC believes that the proposed rule 
change would not impose any burden or impact on competition not 
necessary or appropriate in furtherance of the purposes of the Exchange 
Act.

(C) Clearing Agency's Statement on Comments on the Proposed Rule Change 
Received From Members, Participants, or Others

    Written comments were not and are not intended to be solicited with 
respect to the proposed change and none have been received.

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