Self-Regulatory Organizations; Fixed Income Clearing Corporation; 
Notice of Advance Notice Filing of Proposed Changes to the Method of 
Calculating Netting Members' Margin in the Government Securities 
Division Rulebook

February 26, 2018.
    Pursuant to Section 806(e)(1) of Title VIII of the Dodd-Frank Wall 
Street Reform and Consumer Protection Act entitled the Payment, 
Clearing, and Settlement Supervision Act of 2010 (``Clearing 
Supervision Act'') \1\ and Rule 19b-4(n)(1)(i) under the Securities 
Exchange Act of 1934 as amended (``Act''),\2\ notice is hereby given 
that on January 12, 2018, Fixed Income Clearing Corporation (``FICC'') 
filed with the Securities and Exchange Commission (``Commission'') the 
advance notice SR-FICC-2018-801 (``Advance Notice'') as described in 
Items I, II and III below, which Items have been prepared by the 
clearing agency.\3\ The Commission is publishing this notice to solicit 
comments on the Advance Notice from interested persons.
---------------------------------------------------------------------------

    \1\ 12 U.S.C. 5465(e)(1).
    \2\ 17 CFR 240.19b-4(n)(1)(i).
    \3\ On January 12, 2018, FICC also filed a proposed rule change 
(SR-FICC-2018-001) with the Commission pursuant to Section 19(b)(1) 
of the Act, 15 U.S.C. 78s(b)(1), and Rule 19b-4, 17 CFR 240.19b-4, 
seeking approval of changes to its rules necessary to implement the 
proposal. A copy of the proposed rule change is available at http://www.dtcc.com/legal/sec-rule-filings.aspx.
---------------------------------------------------------------------------

I. Clearing Agency's Statement of the Terms of Substance of the Advance 
Notice

    This Advance Notice consists of amendments to FICC's Government 
Securities Division (``GSD'') Rulebook (the ``GSD Rules'') \4\ in order 
to propose changes to GSD's method of calculating Netting Members' 
margin, referred to in the GSD Rules as the Required Fund Deposit 
amount.\5\ Specifically, FICC is proposing to (1) change its method of 
calculating the VaR Charge component, (2) add a new component referred 
to as the ``Blackout Period Exposure Adjustment'' (as defined in Item 
II.(B)I below), (3) eliminate the Blackout Period Exposure Charge and 
the Coverage Charge components, (4) amend the Backtesting Charge 
component to (i) include the backtesting deficiencies of certain GCF 
Counterparties during the Blackout Period \6\ and (ii) give GSD the 
ability to assess the Backtesting Charge on an intraday basis for all 
Netting Members, and (5) amend the calculation for determining the 
Excess Capital Premium for Broker Netting Members, Inter-Dealer Broker 
Netting Members and Dealer Netting Members. In addition, FICC is 
proposing to provide transparency with respect to GSD's existing 
authority to calculate and assess Intraday Supplemental Fund Deposit 
amounts.\7\
---------------------------------------------------------------------------

    \4\ Available at DTCC's website, www.dtcc.com/legal/rules-and-procedures.aspx. Capitalized terms used herein and not defined shall 
have the meaning assigned to such terms in the GSD Rules.
    \5\ Id. at GSD Rules 1 and 4.
    \6\ As further discussed in Item II.(B)I. below, the proposed 
Backtesting Charge would consider a GCF Counterparty's backtesting 
deficiencies that are attributable to GCF Repo Transactions 
collateralized with mortgage-backed securities during the Blackout 
Period.
    \7\ Pursuant to the GSD Rules, FICC has the existing authority 
and discretion to calculate an additional amount on an intraday 
basis in the form of an Intraday Supplemental Clearing Fund Deposit. 
See GSD Rules 1 and 4, Section 2a, supra note 4.
---------------------------------------------------------------------------

    FICC has also provided the following documentation to the 
Commission:
    1. Backtesting results that reflect FICC's comparison of the 
aggregate Clearing Fund requirement (``CFR'') under GSD's current 
methodology and the aggregate CFR under the proposed methodology (as 
listed in the first paragraph above) to historical returns of end-of-
day snapshots of each Netting Member's portfolio for the period May 
2016 through October 2017. The CFR backtesting results under the 
proposed methodology were calculated in two ways for end-of-day 
portfolios: One set of results included the proposed Blackout Period 
Exposure Adjustment and the other set of results excluded the proposed 
Blackout Period Exposure Adjustment.
    2. An impact study that shows the portfolio level VaR Charge under 
the proposed methodology for the period January 3, 2013 through 
December 30, 2016,\8\ and
---------------------------------------------------------------------------

    \8\ This period includes market stress events such as the U.S. 
presidential election, United Kingdom's vote to leave the European 
Union, and the 2013 spike in U.S. Treasury yields which resulted 
from the Federal Reserve's plans to reduce its balance sheet 
purchases.
---------------------------------------------------------------------------

    3. An impact study that shows the aggregate Required Fund Deposit 
amount by Netting Member for the period May 1, 2017 through November 
30, 2017.
    4. The GSD Initial Margin Model (the ``QRM Methodology'') which 
would reflect the proposed methodology of the VaR Charge calculation 
and the proposed Blackout Period Exposure Adjustment.
    FICC is requesting confidential treatment of the above-referenced 
backtesting results, impact studies and QRM Methodology, and has filed 
it separately with the Commission.\9\
---------------------------------------------------------------------------

    \9\ See 17 CFR 240-24b-2.
---------------------------------------------------------------------------

II. Clearing Agency's Statement of the Purpose of, and Statutory Basis 
for, the Advance Notice

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

(A) Clearing Agency's Statement on Comments on the Advance Notice 
Received From Members, Participants, or Others

    Written comments relating to the proposed rule changes have not 
been solicited or received. FICC will notify the Commission of any 
written comments received by FICC.

(B) Advance Notice Filed Pursuant to Section 806(e) of the Payment, 
Clearing and Settlement Supervision Act

I. Description of the Change

    The purpose of this filing is to amend the GSD Rules to propose 
changes to GSD's method of calculating Netting Members' margin, 
referred to in the GSD Rules as the Required Fund Deposit amount. 
Specifically, FICC is proposing to (1) change its method of calculating 
the VaR Charge component, (2) add the Blackout Period Exposure 
Adjustment

[[Page 9056]]

as a new component, (3) eliminate the Blackout Period Exposure Charge 
and the Coverage Charge components, (4) amend the Backtesting Charge to 
(i) consider the backtesting deficiencies of certain GCF Counterparties 
during the Blackout Period \10\ and (ii) give GSD the ability to assess 
the Backtesting Charge on an intraday basis for all Netting Members, 
and (5) amend the calculation for determining the Excess Capital 
Premium for Broker Netting Members, Dealer Netting Members and Inter-
Dealer Broker Netting Members.
---------------------------------------------------------------------------

    \10\ As further discussed below, the proposed Backtesting Charge 
would consider a GCF Counterparty's backtesting deficiencies that 
are attributable to GCF Repo Transactions collateralized with 
mortgage-backed securities during the Blackout Period.
---------------------------------------------------------------------------

    In addition, FICC is proposing to provide transparency with respect 
to GSD's existing authority to calculate and assess Intraday 
Supplemental Fund Deposit amounts.\11\
---------------------------------------------------------------------------

    \11\ Pursuant to the GSD Rules, FICC has the existing authority 
and discretion to calculate an additional amount on an intraday 
basis in the form of an Intraday Supplemental Clearing Fund Deposit. 
See GSD Rules 1 and 4, Section 2a, supra note 4.
---------------------------------------------------------------------------

    The proposed QRM Methodology would reflect the proposed methodology 
of the VaR Charge calculation and the proposed Blackout Period Exposure 
Adjustment calculation.

A. The Required Fund Deposit and Clearing Fund Calculation Overview

    GSD provides trade comparison, netting and settlement for the U.S. 
Government securities marketplace. Pursuant to the GSD Rules, Netting 
Members may process the following securities and transaction types 
through GSD: (1) Buy-sell transactions in eligible U.S. Treasury and 
Agency securities, (2) delivery versus payment repurchase agreement 
(``repo'') transactions, where the underlying collateral must be U.S. 
Treasury securities or Agency securities, and (3) GCF Repo 
Transactions, where the underlying collateral must be U.S. Treasury 
securities, Agency securities, or eligible mortgage-backed securities.
    A key tool that FICC uses to manage counterparty risk is the daily 
calculation and collection of Required Fund Deposits from Netting 
Members.\12\ The Required Fund Deposit serves as each Netting Member's 
margin. Twice each business day, Netting Members are required to 
satisfy their Required Fund Deposit by 9:30 a.m. (E.T.) (the ``AM 
RFD'') and 2:45 p.m. (E.T.) (the ``PM RFD''). The aggregate of all 
Netting Members' Required Fund Deposits constitutes the Clearing Fund 
of GSD, which FICC would access should a defaulting Netting Member's 
own Required Fund Deposit be insufficient to satisfy losses to GSD 
caused by the liquidation of that Netting Member's portfolio. The 
objective of a Netting Member's Required Fund Deposit is to mitigate 
potential losses to GSD associated with liquidation of such Member's 
portfolio in the event that FICC ceases to act for such Member 
(hereinafter referred to as a ``default'').
---------------------------------------------------------------------------

    \12\ See GSD Rules 1 and 4, supra note 4.
---------------------------------------------------------------------------

    As discussed below, a Netting Member's Required Fund Deposit 
currently consists of the VaR Charge and, to the extent applicable, the 
Coverage Charge, the Blackout Period Exposure Charge, the Backtesting 
Charge, the Excess Capital Premium, and other components.\13\
---------------------------------------------------------------------------

    \13\ Pursuant to the GSD Rules, the Required Fund Deposit 
calculation may include the following additional components: The 
Holiday Charge, the Cross-Margining Reduction, the GCF Premium 
Charge, the GCF Repo Event Premium, the Early Unwind Intraday Charge 
and the Special Charge. See GSD Rules 1 and 4, supra note 4. FICC is 
not proposing any changes to these components, thus a description of 
these components is not included in this rule filing.
---------------------------------------------------------------------------

1. GSD's Required Fund Deposit Calculation--The VaR Charge Component
    The VaR Charge generally comprises the largest portion of a Netting 
Member's Required Fund Deposit amount. Currently, GSD uses a 
methodology referred to as the ``full revaluation'' approach to capture 
the market price risk associated with the securities in a Netting 
Member's portfolio. The full revaluation approach uses valuation 
algorithms to fully reprice each security in a Netting Member's 
portfolio over a range of historically simulated scenarios. These 
historical market moves are then used to project the potential gains or 
losses that could occur in connection with the liquidation of a 
defaulting Netting Member's portfolio to determine the amount of the 
VaR Charge, which is calibrated to cover the projected liquidation 
losses at a 99% confidence level.
    The VaR Charge provides an estimate of the possible losses for a 
given portfolio based on a given confidence level over a particular 
time horizon. The current VaR Charge is calibrated at a 99% confidence 
level based on a front-weighted \14\ 1-year look-back period assuming a 
three-day liquidation period.\15\ In the event that FICC determines 
that certain classes of securities in a Netting Member's portfolio 
(including, but not limited to, the repo rate for Term Repo 
Transactions and Forward-Starting Repo Transactions) are less amenable 
to statistical analysis,\16\ FICC may apply a historic index volatility 
model rather than the VaR calculation.\17\
---------------------------------------------------------------------------

    \14\ A fronted weighted approach means that GSD allows recently 
observed market data to have more impact on the VaR Charge than 
older historic market data.
    \15\ The three-day liquidation period is sometimes referred to 
as the ``margin period of risk'' or ``closeout-period.'' This period 
reflects the time between the most recent collection of the Required 
Fund Deposit from a defaulting Netting Member and the liquidation of 
such Netting Member's portfolio. FICC currently assumes that it 
would take three days to liquidate or hedge a portfolio in normal 
market conditions.
    \16\ Certain classes of securities are less amenable to 
statistical analysis because FICC believes that it does not observe 
sufficient historical market price data to reliably estimate the 99% 
confidence level.
    \17\ See GSD Rule 4 Section 1b(a), supra note 4.
---------------------------------------------------------------------------

    In addition to the full revaluation approach that GSD uses to 
calculate the VaR Charge, GSD also utilizes ``implied volatility 
indicators'' among the assumptions and other observable market data as 
part of its volatility model. Specifically, GSD applies a multiplier 
(also known as the ``augmented volatility adjustment multiplier'') to 
calculate the VaR Charge. The multiplier is based on the levels of 
change in current and implied volatility measures of market benchmarks.
    FICC also employs a supplemental risk charge referred to as the 
Margin Proxy.\18\ The Margin Proxy is designed to help ensure that each 
Netting Member's VaR Charge is adequate and, at the minimum, mirrors 
historical price moves.
---------------------------------------------------------------------------

    \18\ The Margin Proxy is currently used to provide supplemental 
coverage to the VaR Charge, however, pursuant to this rule filing, 
the Margin Proxy would only be used as an alternative volatility 
calculation as described below in subsection B.3.--Proposed change 
to implement the Margin Proxy as the VaR Charge during a vendor data 
disruption.
---------------------------------------------------------------------------

2. GSD's Required Fund Deposit Calculation--Other Components
    In addition to the VaR Charge, a Netting Member's Required Fund 
Deposit calculation may include a number of other components including, 
but not limited to, the Coverage Charge, the Blackout Period Exposure 
Charge, and the Backtesting Charge.\19\ In addition, the Required Fund 
Deposit may include an Excess Capital Premium charge.\20\
---------------------------------------------------------------------------

    \19\ See supra note 13.
    \20\ See GSD Rules 1 and 3, Section 1, supra note 4.
---------------------------------------------------------------------------

    The Coverage Charge is designed to address potential shortfalls 
\21\ in the margin amount calculated by the existing VaR Charge and 
Funds-Only

[[Page 9057]]

Settlement.\22\ Thus, the Coverage Charge is applied to supplement the 
VaR Charge to help ensure that a Netting Member's backtesting coverage 
achieves the 99% confidence level.
---------------------------------------------------------------------------

    \21\ While multiple factors may contribute to a shortfall, 
shortfalls could be observed based on the mark-to-market change on a 
Netting Member's positions after the last margin collection.
    \22\ The Coverage Charge is calculated as the front-weighted 
average of backtesting coverage deficiencies observed over the prior 
100 days. The backtesting coverage deficiencies are determined by 
comparing (x) the simulated liquidation profit and loss of a Netting 
Member's portfolio (using actual positions in the Member's portfolio 
and the actual historical returns on the security positions in the 
portfolio) to (y) the sum of the VaR Charge and the Funds-Only 
Settlement Amount (which is the mark-to-market amount) in order to 
determine whether there would have been any shortfalls between the 
amounts collected.
---------------------------------------------------------------------------

    The Blackout Period Exposure Charge is applied when FICC determines 
that a GCF Counterparty has experienced backtesting deficiencies due to 
reductions in the notional value of the mortgage-backed securities used 
to collateralize its GCF Repo Transactions during the monthly Blackout 
Period. This charge is designed to mitigate FICC's exposure resulting 
from potential decreases in the collateral value of mortgage-backed 
securities that occur during the monthly Blackout Period.
    The Backtesting Charge is applied when FICC determines that a 
Netting Member's portfolio has experienced backtesting deficiencies 
over the prior 12-month period. The Backtesting Charge is designed to 
mitigate exposures to GSD caused by settlement risks that may not be 
adequately captured by GSD's Required Fund Deposit.
    The Excess Capital Premium is applied to a Netting Member's 
Required Fund Deposit when its VaR Charge exceeds its Excess Capital. 
The Excess Capital Premium is designed to more effectively manage a 
Netting Member's credit risk to GSD that is caused because such Netting 
Member's trading activity has resulted in a VaR Charge that is greater 
than its excess regulatory capital.
3. GSD's Backtesting Process
    FICC employs daily backtesting to determine the adequacy of each 
Netting Member's Required Fund Deposit. Backtesting compares the 
Required Fund Deposit for each Netting Member with actual price changes 
in the Netting Member's portfolio. The portfolio values are calculated 
using the actual positions in a Netting Member's portfolio on a given 
day and the observed security price changes over the following three 
days. The backtesting results are reviewed by FICC as part of its 
performance monitoring and assessment of the adequacy of each Netting 
Member's Required Fund Deposit. As noted above, a Backtesting Charge 
may be assessed if GSD determines that a Netting Member's Required Fund 
Deposit may not fully address the projected liquidation losses 
estimated from such Netting Member's settlement activity. Similarly, 
the Coverage Charge may be assessed to address potential shortfalls in 
the VaR Charge calculation. The Coverage Charge supplements the VaR 
Charge to help ensure that the Netting Member's backtesting coverage 
achieves the 99% confidence level. The Coverage Charge considers the 
backtesting results of only the VaR Charge (including the augmented 
volatility adjustment multiplier) and mark-to-market, while the 
Backtesting Charge considers the total Required Fund Deposit amount.

B. Proposed Changes to GSD's Calculation of the VaR Charge

    FICC is proposing to amend its calculation of GSD's VaR Charge 
because during the fourth quarter of 2016, FICC's current methodology 
for calculating the VaR Charge did not respond effectively to the 
market volatility that existed at that time. As a result, the VaR 
Charge did not achieve backtesting coverage at a 99% confidence level 
and therefore yielded backtesting deficiencies beyond FICC's risk 
tolerance. In response, FICC implemented the Margin Proxy to help 
ensure that each Netting Member's VaR Charge achieves a minimum 99% 
confidence level and, at the minimum, mirrors historical price moves, 
while FICC continued the development effort on the proposed sensitivity 
based approach to remediate the observed model weaknesses.\23\
---------------------------------------------------------------------------

    \23\ See supra note 18.
---------------------------------------------------------------------------

    As a result of FICC's review of GSD's existing VaR model 
deficiencies, FICC is proposing to: (1) Replace the full revaluation 
approach with the sensitivity approach, (2) eliminate the augmented 
volatility adjustment multiplier, (3) employ the Margin Proxy as an 
alternative volatility calculation rather than as a minimum volatility 
calculation, (4) utilize a haircut method for securities that lack 
sufficient historical data, and (5) establish a minimum calculation, 
referred to as the VaR Floor (as defined below in subsection 5), as the 
minimum VaR Charge. These proposed changes are described in detail 
below.
1. Proposed Change To Replace the Full Revaluation Approach With the 
Sensitivity Approach
    FICC is proposing to address GSD's existing VaR model deficiencies 
by replacing the full revaluation method with the sensitivity 
approach.\24\ The current full revaluation approach uses valuation 
algorithms to fully reprice each security in a Netting Member's 
portfolio over a range of historically simulated scenarios. While there 
are benefits to this method, some of its deficiencies are that it 
requires significant historical market data inputs, calibration of 
various model parameters and extensive quantitative support for price 
simulations.
---------------------------------------------------------------------------

    \24\ GSD's proposed sensitivity approach is similar to the 
sensitivity approach that FICC's Mortgage-Backed Securities Division 
(``MBSD'') uses to calculate the VaR Charge for MBSD clearing 
members. See MBSD's Clearing Rules, available at DTCC's website, 
www.dtcc.com/legal/rules-and-procedures.aspx. See Securities 
Exchange Act Release No. 79868 (January 24, 2017) 82 FR 8780 
(January 30, 2017) (SR-FICC-2016-007) and Securities Exchange Act 
Release No. 79643 (December 21, 2016), 81 FR 95669 (December 28, 
2016) (SR-FICC-2016-801).
---------------------------------------------------------------------------

    FICC believes that the proposed sensitivity approach would address 
these deficiencies because it would leverage external vendor \25\ 
expertise in supplying the market risk attributes, which would then be 
incorporated by FICC into GSD's model to calculate the VaR Charge. 
Specifically, FICC would source security-level risk sensitivity data 
and relevant historical risk factor time series data from an external 
vendor for all Eligible Securities.
---------------------------------------------------------------------------

    \25\ FICC does not believe that its engagement of the vendor 
would present a conflict of interest because the vendor is not an 
existing Netting Member nor are any of the vendor's affiliates 
existing Netting Members. To the extent that the vendor or any of 
its affiliates submit an application to become a Netting Member, 
FICC will negotiate an appropriate information barrier with the 
applicant in an effort to prevent a conflict of interest from 
arising. An affiliate of the vendor currently provides an existing 
service to FICC; however, this arrangement does not present a 
conflict of interest because the existing agreement between FICC and 
the vendor, and the existing agreement between FICC and the vendor's 
affiliate each contain provisions that limit the sharing of 
confidential information.
---------------------------------------------------------------------------

    The sensitivity data would be generated by a vendor based on its 
econometric, risk and pricing models.\26\

[[Page 9058]]

Because the quality of this data is an important component of 
calculating the VaR Charge, FICC would conduct independent data checks 
to verify the accuracy and consistency of the data feed received from 
the vendor. With respect to the historical risk factor time series 
data, FICC has evaluated the historical price moves and determined 
which risk factors primarily explain those price changes, a practice 
commonly referred to as risk attribution.
---------------------------------------------------------------------------

    \26\ The following risk factors would be incorporated into GSD's 
proposed sensitivity approach: Key rate, convexity, implied 
inflation rate, agency spread, mortgage-backed securities spread, 
volatility, mortgage basis, and time risk factor. These risk factors 
are defined as follows:
     Key rate measures the sensitivity of a price change to 
changes in interest rates;
     convexity measures the degree of curvature in the 
price/yield relationship of key interest rates;
     implied inflation rate measures the difference between 
the yield on an ordinary bond and the yield on an inflation-indexed 
bond with the same maturity;
     agency spread is yield spread that is added to a 
benchmark yield curve to discount an Agency bond's cash flows to 
match its market price;
     mortgage-backed securities spread is the yield spread 
that is added to a benchmark yield curve to discount a to-be-
announced (``TBA'') security's cash flows to match its market price;
     volatility reflects the implied volatility observed 
from the swaption market to estimate fluctuations in interest rates;
     mortgage basis captures the basis risk between the 
prevailing mortgage rate and a blended Treasury rate; and
     time risk factor accounts for the time value change (or 
carry adjustment) over the assumed liquidation period.
    The above-referenced risk factors are similar to the risk 
factors currently utilized in MBSD's sensitivity approach, however, 
GSD has included other risk factors that are specific to the U.S. 
Treasury securities, Agency securities and mortgage-backed 
securities cleared through GSD.
    Concerning U.S. Treasury securities and Agency securities, FICC 
would select the following risk factors: Key rates, convexity, 
agency spread, implied inflation rates, volatility, and time.
    For mortgage-backed securities, each security would be mapped to 
a corresponding TBA forward contract and FICC would use the risk 
exposure analytics for the TBA as an estimate for the mortgage-
backed security's risk exposure analytics. FICC would use the 
following risk factors to model a TBA security: Key rates, 
convexity, mortgage-backed securities spread, volatility, mortgage 
basis, and time. To account for differences between mortgage-backed 
securities and their corresponding TBA, FICC would apply an 
additional basis risk adjustment.
---------------------------------------------------------------------------

    FICC's proposal to use the vendor's risk analytics data requires 
that FICC take steps to mitigate potential model risk. FICC has 
reviewed a description of the vendor's calculation methodology and the 
manner in which the market data is used to calibrate the vendor's 
models. FICC understands and is comfortable with the vendor's controls, 
governance process and data quality standards. FICC would conduct an 
independent review of the vendor's release of a new version of its 
model prior to using it in GSD's proposed sensitives approach 
calculation. In the event that the vendor changes its model and 
methodologies that produce the risk factors and risk sensitivities, 
FICC would analyze the effect of the proposed changes on GSD's proposed 
sensitivity approach. Future changes to the QRM Methodology would be 
subject to a proposed rule change pursuant to Rule 19b-4 (``Rule 19b-
4'') \27\ of the Act and may be subject to an advance notice filing 
pursuant to Section 806(e)(1) of the Clearing Supervision Act \28\ and 
Rule 19b-4(n)(1)(I) under the Act.\29\ Modifications to the proposed 
VaR Charge may be subject to a proposed rule change pursuant to Rule 
19b-4 \30\ and/or an advance notice filing pursuant to Section 
806(e)(1) of the Clearing Supervision Act \31\ and Rule 19b-4(n)(1)(I) 
under the Act.\32\
---------------------------------------------------------------------------

    \27\ See 17 CFR 240.19b-4.
    \28\ See 12 U.S.C. 5465(e)(1).
    \29\ See 17 CFR 240.19b-4(n)(1)(I).
    \30\ See 17 CFR 240.19b-4.
    \31\ See 12 U.S.C. 5465(e)(1).
    \32\ See 17 CFR 240.19b-4(n)(1)(I).
---------------------------------------------------------------------------

    Under the proposed approach, a Netting Member's portfolio risk 
sensitivities would be calculated by FICC as the aggregate of the 
security level risk sensitivities weighted by the corresponding 
position market values. More specifically, FICC would look at the 
historical changes of the chosen risk factors during the look-back 
period in order to generate risk scenarios to arrive at the market 
value changes for a given portfolio. A statistical probability 
distribution would be formed from the portfolio's market value changes, 
which are then calibrated to cover the projected liquidation losses at 
a 99% confidence level. The portfolio risk sensitivities and the 
historical risk factor time series data would then be used by FICC's 
risk model to calculate the VaR Charge for each Netting Member.
    The proposed sensitivity approach differs from the current full 
revaluation approach mainly in how the market value changes are 
calculated. The full revaluation approach accounts for changes in 
market variables and instrument specific characteristics of U.S. 
Treasury/Agency securities and mortgage-backed securities by 
incorporating certain historical data to calibrate a pricing model that 
generates simulated prices. This data is used to create a distribution 
of returns per each security. By comparison, the proposed sensitivity 
approach would simulate the market value changes of a Netting Member's 
portfolio under a given market scenario as the sum of the portfolio 
risk factor exposures multiplied by the corresponding risk factor 
movements.
    FICC believes that the sensitivity approach would provide three key 
benefits. First, the sensitivity approach incorporates a broad range of 
structured risk factors and a Netting Member portfolios' exposure to 
these risk factors, while the full revaluation approach is calibrated 
with only security level historical data that is supplemented by the 
augmented volatility adjustment multiplier. The proposed sensitivity 
approach integrates both observed risk factor changes and current 
market conditions to more effectively respond to current market price 
moves that may not be reflected in the historical price moves combined 
with the augmented volatility adjustment multiplier. In this regard, 
FICC has concluded, based on its assessment of the backtesting results 
of the proposed sensitivity approach and its comparison of those 
results to the backtesting results of the current full revaluation 
approach \33\ that the proposed sensitivity approach would address the 
deficiencies observed in the existing model because it would leverage 
external vendor expertise, which FICC does not need to develop in-
house, in supplying the market risk attributes that would then be 
incorporated by FICC into GSD's model to calculate the VaR Charge. With 
respect to FICC's review of the backtesting results, FICC believes that 
the calculation of the VaR Charge using the proposed sensitivity 
approach would provide better coverage on volatile days while not 
significantly increasing the overall Clearing Fund.\34\ In fact, the 
calculation of the VaR Charge using the proposed sensitivity approach 
would produce a VaR Charge amount that is consistent with the current 
VaR Charge calculation, as supplemented by Margin Proxy.\35\
---------------------------------------------------------------------------

    \33\ The backtesting results compared the aggregate CFR under 
the current methodology and the aggregate CFR under the proposed 
methodology to historical returns of end-of-day snapshots of each 
Netting Member's portfolio for the period May 2016 through October 
2017. The CFR backtesting results under the proposed methodology 
were calculated in two ways for end-of-day portfolios: One set of 
results included the proposed Blackout Period Exposure Adjustment 
and the other set of results excluded the proposed Blackout Period 
Exposure Adjustment.
    \34\ The CFR backtesting results under the proposed methodology 
(both with and without Blackout Period Exposure Adjustment) indicate 
that the proposed methodology provided better overall coverage 
during the volatile period following the U.S. election than under 
the current methodology. The CFR Backtesting results under the 
proposed methodology were also more stable over the May 2016 through 
October 2017 study period than the CFR backtesting results under the 
existing methodology.
    \35\ FICC implemented the Margin Proxy at the end of April 2017. 
As a result, the CFR backtesting coverage under the current 
methodology increased in May 2017 and were more consistent with the 
CFR backtesting results under the proposed methodology from May 2017 
through October 2017. Based on data reflected in the impact study, 
FICC observes that for the period May 1, 2017 to November 30, 2017 
an approximate 7% increase in average aggregate AM RFD across all 
Netting Members.
---------------------------------------------------------------------------

    The second benefit of the proposed sensitivity approach is that it 
would provide more transparency to Netting Members. Because Netting 
Members typically use risk factor analysis for their own risk and 
financial reporting, such Members would have comparable data and 
analysis to assess the variation in their VaR Charge based on changes 
in

[[Page 9059]]

the market value of their portfolios. Thus, Netting Members would be 
able to simulate the VaR Charge to a closer degree than under the 
existing full revaluation approach.
    The third benefit of the proposed sensitivity approach is that it 
would provide FICC with the ability to adjust the look-back period that 
FICC uses for purposes of calculating the VaR Charge. Specifically, 
FICC would change the look-back period from a front-weighted \36\ 1-
year look-back (which is currently utilized today) to a 10-year look-
back period that is not front-weighted and would include, to the extent 
applicable, an additional stressed period.\37\ The proposed extended 
look-back period would help to ensure that the historical simulation 
contains a sufficient number of historical market conditions (including 
but not limited to stressed market conditions).
---------------------------------------------------------------------------

    \36\ A front-weighted look-back period assigns more weight to 
the most recent market observations thus effectively diminishing the 
value of older market observations. The front-weighted approach is 
based on the assumption that the most recent price history is more 
relevant to current market volatility levels.
    \37\ Under the proposed model, the 10-year look-back period 
would include the 2008/2009 financial crisis scenario. To the extent 
that an equally or more stressed market period does not occur when 
the 2008/2009 financial crisis period is phased out from the 10-year 
look-back period (i.e., from September 2018 onward), pursuant to the 
QRM methodology document, FICC would continue to include the 2008/
2009 financial crisis scenario in its historical scenarios. However, 
if an equally or more stressed market period emerges in the future, 
FICC may choose not to augment its 10-year historical scenarios with 
those from the 2008/2009 financial crisis.
---------------------------------------------------------------------------

    While FICC could extend the 1-year look-back period in the existing 
full revaluation approach to a 10-year look-back period, the 
performance of the existing model could deteriorate if current market 
conditions are materially different than indicated in the historical 
data. Additionally, since the full revaluation approach requires FICC 
to maintain in-house complex pricing models and mortgage prepayment 
models, enhancing these models to extend the look-back period to 
include 10 years of historical data involves significant model 
development. The sensitivity approach, on the other hand, would 
leverage external vendor data to incorporate a longer look-back period 
of 10 years, which would allow the proposed model to capture periods of 
historical volatility.
    In the event FICC observes that the 10-year look-back period does 
not contain a sufficient number of stressed market conditions, FICC 
would have the ability to include an additional period of historically 
observed stressed market conditions to a 10-year look-back period or 
adjust the length of look-back period. The additional stress period is 
a designed to be a continuous period (typically 1 year). FICC believes 
that it is appropriate to assess on an annual basis whether an 
additional stressed period should be included. This assessment, which 
will only occur annually, would include a review of (1) the largest 
moves in the dominating market risk factor of the proposed sensitivity 
approach, (2) the impact analyses resulting from the removal and/or 
addition of a stressed period, and (3) the backtesting results of the 
proposed look-back period. As described in the QRM Methodology, 
approval by DTCC's Model Risk Governance Committee (``MRGC'') and, to 
the extent necessary, the Management Risk Committee (``MRC'') would be 
required to determine when to apply an additional period of stressed 
market conditions to the look-back period and the appropriate 
historical stressed period to utilize if it is not within the current 
10-year period.
2. Proposed Change To Amend the VaR Charge To Eliminate the Augmented 
Volatility Adjustment Multiplier
    As described above, the augmented volatility adjustment multiplier 
gives GSD the ability to adjust its volatility calculations as needed 
to improve the performance of its VaR the model in periods of market 
volatility. The augmented volatility adjustment multiplier was designed 
to mitigate the effect of the 1-year look[hyphen]back period used in 
the existing full revaluation approach because it allowed the model to 
better react to conditions that may not have been within the recent 
historical one-year period. FICC is proposing to eliminate the 
augmented volatility adjustment multiplier because it would be no 
longer necessary given that the proposed sensitivity approach would 
have a longer look-back period and the ability to include an additional 
stressed market condition to account for periods of market volatility.
3. Proposed Change To Implement the Margin Proxy as the VaR Charge 
During a Vendor Data Disruption
a. Vendor Data Disruption
    In connection with FICC's proposal to source data for the proposed 
sensitivity approach, FICC is also proposing procedures that would 
govern in the event that the vendor fails to provide risk analytics 
data. If the vendor fails to provide any data or a significant portion 
of the data timely, FICC would use the most recently available data on 
the first day that such data disruption occurs. If it is determined 
that the vendor will resume providing data within five (5) business 
days, FICC's management would determine whether the VaR Charge should 
continue to be calculated by using the most recently available data 
along with an extended look-back period or whether the Margin Proxy 
should be invoked, subject to the approval of DTCC's Group Chief Risk 
Officer or his/her designee. If it is determined that the data 
disruption will extend beyond five (5) business days, the Margin Proxy 
would be applied as an alternative volatility calculation for the VaR 
Charge subject to the proposed VaR Floor.\38\ FICC's proposed use of 
the Margin Proxy would be subject to the approval of the MRC followed 
by notification to FICC's Board Risk Committee. FICC would continue to 
calculate the Margin Proxy on a daily basis and this calculation would 
continue to reflect separate calculations for U.S. Treasury/Agency 
securities and mortgage-backed securities.\39\ The Margin Proxy would 
be subject to monthly performance review by the MRGC. FICC would 
monitor the performance of the Margin Proxy calculation on a monthly 
basis to ensure that it could be used in the circumstance described 
above. Specifically, FICC would monitor each Netting Member's Required 
Fund Deposit and the aggregate Clearing Fund requirements versus the 
requirements calculated by Margin Proxy. FICC would also backtest the 
Margin Proxy results versus the three-day profit and loss based on 
actual market price moves. If FICC observes material differences 
between the Margin Proxy calculations

[[Page 9060]]

and the aggregate Clearing Fund requirement calculated using the 
proposed sensitivity approach, or if the Margin Proxy's backtesting 
results do not meet FICC's 99% confidence level, FICC management may 
recommend remedial actions to the MRGC, and to the extent necessary the 
MRC, such as increasing the look-back period and/or applying an 
appropriate historical stressed period to the Margin Proxy calibration.
---------------------------------------------------------------------------

    \38\ The proposed VaR Floor is defined below in subsection B.5--
Proposed change to amend the VaR Charge calculation to establish a 
VaR Floor.
    \39\ Currently, GSD conducts separate calculations in order to 
cover the historical market prices of U.S. Treasury/Agency 
securities and mortgage-backed securities, respectively, because the 
historical price changes of these asset classes are different as a 
result of market factors such as credit spreads and prepayment risk. 
Separate calculations also provide FICC with the ability to monitor 
the performance of each asset class individually. Each security in a 
Netting Member's Margin Portfolio is mapped to a separate benchmark 
based on the security's asset class and maturity. All securities 
within each benchmark are then aggregated into a net exposure. FICC 
then applies an applicable haircut to the net exposure per benchmark 
to determine the net price risk for each benchmark. Finally, FICC 
determines the asset class price risk (``Asset Class Price Risk'') 
for U.S. Treasury/Agency securities and mortgage-backed securities 
benchmarks separately by aggregating the respective net price risk. 
For the U.S. Treasury benchmarks, the calculation includes a 
correlation adjustment to provide risk diversification across tenor 
buckets that has been historically observed across the U.S. Treasury 
benchmarks. The Margin Proxy is the sum of the U.S. Treasury/Agency 
securities and mortgage-backed securities Asset Class Price Risk. No 
changes are being proposed to this calculation.
---------------------------------------------------------------------------

    As noted above, FICC intends to source certain sensitivity data and 
risk factor data from a vendor. FICC's Quantitative Risk Management, 
Vendor Risk Management, and Information Technology teams have conducted 
due diligence of the vendor in order to evaluate its control framework 
for managing key risks. FICC's due diligence included an assessment of 
the vendor's technology risk, business continuity, regulatory 
compliance, and privacy controls. FICC has existing policies and 
procedures for data management that includes market data and analytical 
data provided by vendors. These policies and procedures do not have to 
be amended in connection with this proposed rule change. FICC also has 
tools in place to assess the quality of the data that it receives from 
vendors.
b. Regulation SCI Implications
    Rule 1001(c)(1) of Regulation Systems Compliance and Integrity 
(``SCI'') requires FICC to establish, maintain, and enforce reasonably 
designed written policies and procedures that include the criteria for 
identifying responsible SCI personnel, the designation and 
documentation of responsible SCI personnel, and escalation procedures 
to quickly inform responsible SCI personnel of potential SCI 
events.\40\ Further, pursuant to Rule 1002 of Regulation SCI, each 
responsible SCI personnel determines when there is a reasonable basis 
to conclude that a SCI event has occurred, which will trigger certain 
obligations of a SCI entity with respect to such SCI events.\41\ FICC 
has existing policies and procedures that reflect established criteria 
that must be used by responsible SCI personnel to determine whether a 
disruption to, or significantly downgrade of, the normal operation of 
FICC's risk management system has occurred as defined under Regulation 
SCI. These policies and procedures do not have to be amended in 
connection with this proposed rule change. In the event that the vendor 
fails to provide the requisite risk analytics data, the responsible SCI 
personnel would determine whether a SCI event has occurred, and FICC 
would fulfill its obligations with respect to the SCI event.
---------------------------------------------------------------------------

    \40\ See 17 CFR 242.1001(c)(1).
    \41\ See 17 CFR 242.1002.
---------------------------------------------------------------------------

4. Proposed Change To Utilize a Haircut Method To Measure the Risk 
Exposure of Securities That Lack Historical Data
    Occasionally, portfolios contain classes of securities that reflect 
market price changes that are not consistently related to historical 
risk factors. The value of these securities is often uncertain because 
the securities' market volume varies widely, thus the price histories 
are limited. Because the volume and price information for such 
securities is not robust, a historical simulation approach would not 
generate VaR Charge amounts that adequately reflect the risk profile of 
such securities. Currently, GSD Rule 4 provides that FICC may use a 
historic index volatility model to calculate the VaR Charge for these 
classes of securities.\42\ FICC is proposing to amend GSD Rule 4 to 
utilize a haircut method based on a historic index volatility model for 
any security that lack sufficient historical data to be incorporated 
into the proposed sensitivity approach.
---------------------------------------------------------------------------

    \42\ See GSD Rule 4, supra note 4.
---------------------------------------------------------------------------

    FICC believes that the proposal to implement a haircut method for 
securities that lack sufficient historical information would allow FICC 
to use appropriate market data to estimate a margin at a 99% confident 
level, thus helping to ensure that sufficient margin would be 
calculated for portfolios that contain these securities. FICC would 
continue to manage the market risk of clearing these securities by 
conducting analysis on the type of securities that cannot be processed 
by the proposed VaR model and engaging in periodic reviews of the 
haircuts used for calculating margin for these types of securities.
    FICC is proposing to calculate the VaR Charge for these securities 
by utilizing a haircut approach based on a market benchmark with a 
similar risk profile as the related security. The proposed haircut 
approach would be calculated separately for U.S. Treasury/Agency 
securities (other than (x) treasury floating-rate notes and (y) term 
repo rate volatility for Term Repo Transactions and Forward-Starting 
Repo Transactions (including term and forward-starting GCF Repo 
Transactions)) \43\ and mortgage-backed securities.
---------------------------------------------------------------------------

    \43\ GSD is not proposing any changes to its current approach to 
calculating the VaR Charge for floating rate notes. Currently, GSD 
uses a haircut approach with a constant discount margin movement 
scenario. The discount margin movement scenario is based on the 
current market condition of the floating rate note price movements. 
This amount plus the calculated discount margin sensitivity of each 
floating rate note issue's market price plus the formula provided by 
the U.S. Department of Treasury equals the haircut of the floating 
rate note portion of a Netting Member's portfolio. GSD is also not 
proposing any change to its current approach to calculating the VaR 
Charge for repo interest volatility, which is based on internally 
constructed repo interest rate indices.
---------------------------------------------------------------------------

    Specifically, each security in a Netting Member's portfolio would 
be mapped to a respective benchmark based on the security's asset class 
and remaining maturity, then all securities within each benchmark would 
be aggregated into a net exposure. FICC would apply an applicable 
haircut to the net exposure per benchmark to determine the net price 
risk for each benchmark. Finally, the net price risk would be 
aggregated across all benchmarks (but separately for U.S. Treasury/
Agency securities and mortgage-backed securities) and a correlation 
adjustment \44\ would be applied to securities mapped to the U.S. 
Treasury benchmarks to provide risk diversification across tenor 
buckets that were historically observed.
---------------------------------------------------------------------------

    \44\ The correlation adjustment is based on 3-day returns during 
a 10-year look-back. It reflects the average amount that the 3-day 
returns of each benchmark moves in relation to one another. The 
correlation adjustment would only be applied for U.S. Treasury and 
Agency indices with maturities greater than 1 year.
---------------------------------------------------------------------------

5. Proposed Change To Amend the VaR Charge Calculation To Establish a 
VaR Floor
    FICC is proposing to amend the existing calculation of the VaR 
Charge to include a minimum amount, which would be referred to as the 
``VaR Floor.'' The proposed VaR Floor would be a calculated amount that 
would be used as the VaR Charge when the sum of the amounts calculated 
by the proposed sensitivity approach and haircut method is less than 
the proposed VaR Floor. FICC's proposal to establish a VaR Floor seeks 
to address the risk that the proposed VaR model calculates a VaR Charge 
that is erroneously low where the gross market value of unsettled 
positions in the Netting Member's portfolio is high and the cost of 
liquidation in the event of a Member default could also be high. This 
would be likely to occur when the proposed VaR model applies 
substantial risk offsets among long and short positions in different 
classes of securities that have a high degree of historical price 
correlation. Because this high degree of historical price correlation 
may not apply in future changing market conditions,\45\ FICC believes 
that it

[[Page 9061]]

would be prudent to apply a VaR Floor that is based upon the market 
value of the gross unsettled positions in the Netting Member's 
portfolio in order to protect FICC against such risk in the event that 
FICC is required to liquidate a large Netting Member's portfolio in 
stressed market conditions.
---------------------------------------------------------------------------

    \45\ For example, and without limitation, certain securities may 
have highly correlated historical price returns, but if future 
market conditions were to substantially change, these historical 
correlations could break down, leading to model-generated offsets 
that would not adequately capture a portfolio's risk.
---------------------------------------------------------------------------

    The VaR Floor would be calculated as the sum of the following two 
components: (1) A U.S. Treasury/Agency bond margin floor and (2) a 
mortgage-backed securities margin floor. The U.S. Treasury/Agency bond 
margin floor would be calculated by mapping each U.S. Treasury/Agency 
security to a tenor bucket, then multiplying the gross positions of 
each tenor bucket by its bond floor rate, and summing the results. The 
bond floor rate of each tenor bucket would be a fraction (which would 
be initially set at 10%) of an index-based haircut rate for such tenor 
bucket. The mortgage-backed securities margin floor would be calculated 
by multiplying the gross market value of the total value of mortgage-
backed securities in a Netting Member's portfolio by a designated 
amount, referred to as the pool floor rate, (which would be initially 
set at 0.05%).\46\ GSD would evaluate the appropriateness of the 
proposed initial floor rates (e.g., the 10% of the benchmark haircut 
rate for U.S. Treasury/Agency securities and 0.05% for mortgage-backed 
securities) at least annually based on backtesting performance and risk 
tolerance considerations.
---------------------------------------------------------------------------

    \46\ For example, assume the pool floor rate is set to 0.05% and 
the bond floor rate is set to 10% of haircut rates. Further assume 
that a Netting Member has a portfolio with gross positions of $2 
billion in mortgage-backed securities and gross positions of U.S. 
Treasury/Agency securities that fall into two tenor buckets--$2 
billion in tenor bucket ``A'' and $3 billion in tenor bucket ``B.'' 
If the haircut rate for tenor bucket ``A'' is 1% and the haircut 
rate for tenor bucket ``B'' is 2%, then the bond floor rate would be 
0.1% and 0.2%, respectively. Therefore, the resulting VaR Floor 
would be $9 million (i.e., ([0.05%] * [$2 billion]) + [0.1%] * [$2 
billion]) + ([0.2%] * [$3 billion])). If the VaR model charge is 
less than $9 million, then the VaR Floor calculation of $9 million 
would be set as the VaR Charge.
---------------------------------------------------------------------------

6. Mitigating Risks of Concentrated Positions
    For the reasons described above, FICC believes that the proposed 
changes to GSD's VaR Charge calculation would allow it to better 
measure and mitigate the risks presented by certain unsettled 
positions, including the risk presented to FICC when those positions 
are concentrated in a particular security.
    One of the risks presented by unsettled positions concentrated in 
an asset class is that FICC may not be able to liquidate or hedge the 
unsettled positions of a defaulted Netting Member in the assumed 
timeframe at the market price in the event of such Netting Member's 
default. Because FICC relies on external market data in connection with 
monitoring exposures to its Members, the market data may not reflect 
the market impact transaction costs associated with the potential 
liquidation as the concentration risk of an unsettled position 
increases. However, FICC believes that, through the proposed changes 
and through existing risk management measures,\47\ it would be able to 
effectively measure and mitigate risks presented when a Netting 
Member's unsettled positions are concentrated in a particular security.
---------------------------------------------------------------------------

    \47\ For example, pursuant to existing authority under GSD Rule 
4, FICC has the discretion to calculate an additional amount 
(``special charge'') applicable to a Margin Portfolio as determined 
by FICC from time to time in view of market conditions and other 
financial and operational capabilities of the Netting Member. FICC 
shall make any such determination based on such factors as FICC 
determines to be appropriate from time to time. See GSD Rule 4, 
supra note 4.
---------------------------------------------------------------------------

    FICC will continue to evaluate its exposures to these risks. Any 
future proposed changes to the margin methodology to address such risks 
would be subject to a separate proposed rule change pursuant Rule 19b-4 
of the Act,\48\ and/or an advance notice pursuant to Section 806(e)(1) 
of the Clearing Supervision Act \49\ and the rules thereunder.
---------------------------------------------------------------------------

    \48\ See 17 CFR 240.19b-4.
    \49\ See 12 U.S.C. 5465(e)(1).
---------------------------------------------------------------------------

C. Proposed Change To Establish the Blackout Period Exposure Adjustment 
as a Component to the Required Fund Deposit Calculation

    FICC is proposing to add a new component to the Required Fund 
Deposit calculation that would be applied to the VaR Charge for all GCF 
Counterparties with GCF Repo Transactions collateralized with mortgage-
backed securities during the monthly Blackout Period (the ``Blackout 
Period Exposure Adjustment''). FICC is proposing this new component 
because it would better protect FICC and its Netting Members from 
losses that could result from overstated values of mortgage-backed 
securities pledged as collateral for GCF Repo Transactions during the 
Blackout Period.
    The proposed Blackout Period Exposure Adjustment would be in the 
form of a charge that is added to the VaR Charge or a credit that would 
reduce the VaR Charge. The proposed Blackout Period Exposure Adjustment 
would be calculated by (1) projecting an average pay-down rate for the 
government sponsored enterprises (Fannie Mae and Freddie Mac) and the 
Government National Mortgage Association (Ginnie Mae), respectively, 
then (2) multiplying the projected pay-down rate \50\ by the net 
positions of mortgage-backed securities in the related program, and (3) 
summing the results from each program. Because the projected pay-down 
rate would be an average of the weighted averages of pay-down rates for 
all active mortgage pools of the related program during the three most 
recent preceding months, it is possible that the proposed Blackout 
Period Exposure Adjustment could overestimate the amount for a GCF 
Counterparty with a portfolio that primarily includes slower paying 
mortgage-backed securities or underestimate the amount for a GCF 
Counterparty with a portfolio that primarily includes faster paying 
mortgage-backed securities. However, FICC believes that projecting the 
pay-down rate separately for each program and weighting the results by 
recently active pools would reduce instances of large under/over 
estimation. FICC would continue to monitor the realized pay-down 
against FICC's weighted average pay-down rates and its vendor's 
projected pay-down rates as part of the model performance monitoring. 
Further, in the event that a GCF Counterparty continues to experience 
backtesting deficiencies, FICC would apply a Backtesting Charge, which 
as described in section F below, would be amended to consider 
backtesting deficiencies attributable to GCF Repo Transactions 
collateralized with mortgage-backed securities during the Blackout 
Period.\51\
---------------------------------------------------------------------------

    \50\ GSD would calculate the projected average pay-down rates 
each month using historical pool factor pay-down rates that are 
weighted by historical positions during each of the prior three 
months. Specifically, the projected pay-down rate for a current 
Blackout Period would be an average of the weighted averages of pay-
down rates for all active mortgage pools of the related program 
during the three most recent preceding months.
    \51\ The proposed changes to the Backtesting Charge are 
described below is section F--Proposed change to amend the 
Backtesting Charge to (i) include backtesting deficiencies 
attributed to GCF Repo Transactions collateralized with mortgage-
backed securities during the Blackout Period and (ii) give GSD the 
authority to assess a Backtesting Charge on an intraday basis.
---------------------------------------------------------------------------

    The proposed Blackout Period Exposure Adjustment would only be 
imposed during the Blackout Period and it would be applied as of the 
morning Clearing Fund call on the Record Date through and including the 
intraday Clearing Fund call on the Factor Date,

[[Page 9062]]

or until the Pool Factors \52\ have been updated to reflect the current 
month's Pool Factors in the GCF Clearing Agent Bank's collateral 
reports.
---------------------------------------------------------------------------

    \52\ Pursuant to the GSD Rules, the term ``Pool Factor'' means, 
with respect to the Blackout Period, the percentage of the initial 
principal that remains outstanding on the mortgage loan pool 
underlying a mortgage-backed security, as published by the 
government-sponsored entity that is the issuer of such security. See 
GSD Rule 1, supra note 4.
---------------------------------------------------------------------------

D. Proposed Change To Eliminate the Existing Blackout Period Exposure 
Charge

    FICC would eliminate the existing Blackout Period Exposure Charge 
\53\ because the proposed Blackout Period Exposure Adjustment (which is 
described in section C above) would be applied to all GCF 
Counterparties with GCF Repo Transactions collateralized with mortgage-
backed securities during the Blackout Period. The existing Blackout 
Period Exposure Charge, on the other hand, only applies to GCF 
Counterparties that have two or more backtesting deficiencies during 
the Blackout Period and whose overall 12-month trailing backtesting 
coverage falls below the 99% coverage target.\54\ FICC believes that 
the Blackout Period Exposure Charge would no longer be necessary 
because the applicability of the proposed Blackout Period Exposure 
Adjustment would better estimate potential changes to the GCF Repo 
Transactions and help to ensure that GCF Counterparties' with GCF Repo 
Transactions collateralized with mortgage-backed securities maintain a 
backtesting coverage above the 99% confidence level. Further, in the 
event that a GCF Counterparty continues to experience backtesting 
deficiencies, FICC would apply a Backtesting Charge, which as described 
in section F below, would be amended to consider backtesting 
deficiencies attributable to GCF Repo Transactions collateralized with 
mortgage-backed securities during the Blackout Period.\55\
---------------------------------------------------------------------------

    \53\ Pursuant to the GSD Rules, FICC imposes a Blackout Period 
Exposure Charge when FICC determines, based on prior backtesting 
deficiencies of a GCF Counterparty's Required Fund Deposit, that the 
GCF Counterparty may experience a deficiency due to reductions in 
the notional value of the mortgage-backed securities used by such 
GCF Counterparty to collateralize its GCF Repo trading activity that 
occur during the monthly Blackout Period. See GSD Rules 1 and 4, 
supra note 4.
    \54\ See GSD Rules 1 and 4, supra note 4.
    \55\ The proposed changes to the Backtesting Charge are 
described below is section F--Proposed change to amend the 
Backtesting Charge to (i) include backtesting deficiencies 
attributed to GCF Repo Transactions collateralized with mortgage-
backed securities during the Blackout Period and (ii) give GSD the 
authority to assess a Backtesting Charge on an intraday basis.
---------------------------------------------------------------------------

E. Proposed Change To Eliminate the Coverage Charge Component From the 
Required Fund Deposit Calculation

    FICC is proposing to eliminate the Coverage Charge component from 
GSD's Required Fund Deposit calculation.\56\ The Coverage Charge 
component is based on historical portfolio activity, which may not be 
indicative of a Netting Member's current risk profile, but was 
determined by FICC to be appropriate to address potential shortfalls in 
margin charges under the current VaR model. FICC is proposing to 
eliminate the Coverage Component because its analysis indicates that 
the sensitivity approach would provide overall better margin coverage.
---------------------------------------------------------------------------

    \56\ See GSD Rules 1 and 4, supra note 4.
---------------------------------------------------------------------------

    As part of the development and assessment of the proposed VaR 
Charge, FICC backtested the model's performance and analyzed the impact 
of the margin changes. Results of the analysis indicated that the 
proposed sensitivity approach would be more responsive to changing 
market dynamics and a Netting Member's portfolio composition coverage 
than the existing VaR model that utilizes the full revaluation 
approach. The backtesting analysis also demonstrated that the proposed 
sensitivity approach would provide sufficient margin coverage on a 
standalone basis. Additionally, in the event that FICC observes 
unexpected deficiencies in the backtesting of a Netting Member's 
Required Fund Deposit, the Backtesting Charge would apply.\57\ Given 
the above, FICC believes the Coverage Charge would no longer be 
necessary.
---------------------------------------------------------------------------

    \57\ Similar to the Coverage Charge, the purpose of the 
Backtesting Charge is to address potential shortfalls in margin 
charges, however, the Coverage Charge considers the backtesting 
results of only the VaR Charge (including the augmented volatility 
adjustment multiplier) and mark-to-market.
---------------------------------------------------------------------------

F. Proposed Change To Amend the Backtesting Charge to (i) Include 
Backtesting Deficiencies Attributable to GCF Repo Transactions 
Collateralized with Mortgage-Backed Securities During the Blackout 
Period and (ii) Give GSD the Authority To Asess a Backtesting Charge on 
an Intraday Basis

    FICC is proposing to amend the Backtesting Charge to (i) include 
backtesting deficiencies attributable to GCF Repo Transactions 
collateralized with mortgage-backed securities during the Blackout 
Period and (ii) give GSD the authority to assess a Backtesting Charge 
on an intraday basis.
(i) Proposed Change To Amend the Backtesting Charge To Include 
Backtesting Deficiencies Attributable to GCF Repo Transactions 
Collateralized With Mortgage-Backed Securities During the Blackout 
Period
    FICC is proposing to amend the Backtesting Charge to provide that 
this charge would be applied to a GCF Counterparty that experiences 
backtesting deficiencies that are attributed to GCF Repo Transactions 
collateralized with mortgage-backed securities during the Blackout 
Period. Currently, Backtesting Charges are not applied to GCF 
Counterparties with collateralized mortgage-backed securities during 
the Blackout Period because such counterparties may be subject to a 
Blackout Period Exposure Charge. However, now that FICC is proposing to 
eliminate the Blackout Period Exposure Charge, FICC is proposing to 
amend the applicability of the Backtesting Charge in the circumstances 
described above.
(ii) Proposed Change To Give GSD the Authority To Assess a Backtesting 
Charge on an Intraday Basis
    FICC is also proposing to amend the Backtesting Charge to provide 
that this charge may be assessed if a Netting Member is experiencing 
backtesting deficiencies during the trading day (i.e., intraday) 
because of such Netting Member's large fluctuations of intraday trading 
activities. A Backtesting Charge that is imposed intraday would be 
referred to as a ``Intraday Backtesting Charge.'' The Intraday 
Backtesting Charge would be assessed on an intraday basis and it would 
increase a Netting Member's Required Fund Deposit to help ensure that 
its intraday backtesting coverage achieves the 99% confidence level.
    The proposed assessment of the Intraday Backtesting Charge differs 
from the existing assessment of the Backtesting Charge because the 
existing assessment is based on the backtesting results of a Netting 
Member's PM RFD versus the historical returns of such Netting Member's 
portfolio at the end of the trading day while the proposed Intraday 
Backtesting Charge would be based on the most recent Required Fund 
Deposit amount that was collected from a Netting Member versus the 
historical returns of such Netting Member's portfolio intraday.
    In an effort to differentiate the proposed Intraday Backtesting 
Charge from the existing Backtesting Charge, FICC is proposing to 
change the name of the existing Backtesting Charge to ``Regular 
Backtesting Charge.'' The

[[Page 9063]]

Intraday Backtesting Charge and the Regular Backtesting Charge would 
collectively be referred to as the Backtesting Charge.
Calculation and Assessment of Intraday Backtesting Charges
    FICC would use a snapshot of each Netting Member's portfolio during 
the trading day,\58\ and compare each Netting Member's AM RFD with the 
simulated liquidation gains/losses using an intraday snapshot of the 
actual positions in the Netting Member's portfolio, and the actual 
historical security returns. FICC would review portfolios with intraday 
backtesting deficiencies that bring the results for that Netting Member 
below the 99% confidence level (i.e., greater than two intraday 
backtesting deficiency days in a rolling twelve-month period) and 
determine whether there is an identifiable cause of ongoing repeat 
backtesting deficiencies. FICC would also evaluate whether multiple 
Netting Members are experiencing backtesting deficiencies due to 
similar underlying reasons.
---------------------------------------------------------------------------

    \58\ The snapshot would occur once a day. The timing of the 
snapshot would be subject to change based upon market conditions 
and/or settlement activity. This snapshot would be taken at the same 
time for all Netting Members. All positions that have settled would 
be excluded. FICC would take additional intraday snapshots and/or 
change the time of the intraday snapshot based upon market 
conditions. FICC would include the positions from the start-of-day 
plus any additional positions up to that time.
---------------------------------------------------------------------------

    As is the case with the existing Backtesting Charge (which would be 
referred to as the ``Regular Backtesting Charge''), the proposed 
Intraday Backtesting Charge would be assessed on Netting Members with 
portfolios that experience at least three intraday backtesting 
deficiencies over the prior 12-month period. The proposed Intraday 
Backtesting Charge would generally equal a Netting Member's third 
largest historical intraday backtesting deficiency because FICC 
believes that an Intraday Backtesting Charge equal to the third largest 
historical intraday backtesting deficiency would bring the affected 
Netting Member's historically observed intraday backtesting coverage 
above the 99% confidence level.
    FICC would have the discretion to adjust the Intraday Backtesting 
Charge to an amount that is more appropriate for maintaining such 
Netting Member's intraday backtesting results above the 99% coverage 
threshold.\59\
---------------------------------------------------------------------------

    \59\ For example, FICC may consider whether the affected Netting 
Member would be likely to experience future intraday backtesting 
deficiencies, the estimated size of such deficiencies, material 
differences in the three largest intraday backtesting deficiencies 
observed over the prior 12-month period, variabilities in its net 
settlement activity subsequent to GSD's collection of the AM RFD, 
seasonality in observed intraday backtesting deficiencies and 
observed market price volatility in excess of its historical VaR 
Charge.
---------------------------------------------------------------------------

    In the event that FICC determines that an Intraday Backtesting 
Charge should apply in the circumstances described above, FICC would 
notify the affected Netting Member prior to its assessment of the 
charge. As is the case with the existing application of the Backtesting 
Charge, FICC would notify Netting Members on or around the 25th 
calendar day of the month.
    The proposed Intraday Backtesting Charge would be applied to the 
affected Netting Member's Required Fund Deposit on a daily basis for a 
one-month period. FICC would review the assessed Intraday Backtesting 
Charge on a monthly basis to determine if the charge is still 
applicable and that the amount charged continues to provide appropriate 
coverage. In the event that an affected Netting Member's trailing 12-
month intraday backtesting coverage exceeds 99% (without taking into 
account historically imposed Intraday Backtesting Charges), the 
Intraday Backtesting Charge would be removed.

G. Proposed Change to the Excess Capital Premium Calculation for Broker 
Netting Members, Inter-Dealer Broker Netting Members and Dealer Netting 
Members

    FICC is proposing to move to a net capital measure for Broker 
Netting Members, Inter-Dealer Broker Netting Members and Dealer Netting 
Members that would align the Excess Capital Premium for such Members to 
a measure that is consistent with the equity capital measure that is 
used for Bank Netting Members in the Excess Capital Premium 
calculation.
    Currently, the Excess Capital Premium is determined based on the 
amount that a Netting Member's Required Fund Deposit exceeds its Excess 
Capital.\60\ Only Netting Members that are brokers or dealers 
registered under Section 15 of the Act are required to report Excess 
Net Capital figures to FICC while other Netting Members report net 
capital or equity capital. If a Netting Member is not a broker/dealer, 
FICC would use net capital or equity capital, as applicable (based on 
the type of regulation that such Netting Member is subject to) in order 
to calculate its Excess Capital Premium.
---------------------------------------------------------------------------

    \60\ Pursuant to the GSD Rules, the term ``Excess Capital'' 
means Excess Net Capital, net assets or equity capital as 
applicable, to a Netting Member based on its type of regulation. See 
GSD Rule 1, supra note 4.
---------------------------------------------------------------------------

    FICC is proposing this change because of the Commission's 
amendments to Rule 15c3-1 (the ``Net Capital Rule''), which were 
adopted in 2013.\61\ The amendments are designed to promote a broker/
dealer's capital quality and require the maintenance of ``net capital'' 
(i.e., capital in excess of liabilities) in specified amounts as 
determined by the type of business conducted. The Net Capital Rule is 
designed to ensure the availability of funds and assets (including 
securities) in the event that a broker/dealer's liquidation becomes 
necessary. The Net Capital Rule represents a net worth perspective, 
which is adjusted by unrealized profit or loss, deferred tax 
provisions, and certain liabilities as detailed in the rule. It also 
includes deductions and offsets, and requires that a broker/dealer 
demonstrate compliance with the Net Capital Rule including maintaining 
sufficient net capital at all times (including intraday).
---------------------------------------------------------------------------

    \61\ See 17 CFR 240.15c3-1. Securities Exchange Act Release No. 
34-70072 (July 30, 2013), 78 FR 51823 (August 21, 2013) (File No. 
S7-08-07).
---------------------------------------------------------------------------

    FICC believes that the Net Capital Rule is an effective process of 
separating liquid and illiquid assets, and computing a broker/dealer's 
regulatory net capital that should replace GSD's existing practice of 
using Excess Net Capital (which is the difference between the Net 
Capital and the minimum regulatory Net Capital) as the basis for the 
Excess Capital Premium.

H. GSD's Existing Calculation and Assessment of Intraday Supplemental 
Fund Deposit Amounts

    Separate and apart from the AM RFD and the PM RFD, the GSD Rules 
give FICC the existing authority to collect Intraday Supplemental Fund 
Deposits from Netting Members.\62\ Through this filing, FICC is 
providing transparency with respect to GSD's existing calculation of 
Intraday Supplemental Fund Deposit amounts.
---------------------------------------------------------------------------

    \62\ As described above in section A.--The Required Fund Deposit 
and Clearing Fund Calculation Overview, GSD calculates and collects 
each Netting Member's Required Fund Deposit twice each business day. 
The AM RFD is collected at 9:30 a.m. (E.T.) and is comprised of a 
VaR Charge that is based on each Netting Member's portfolio at the 
end of the trading day. The PM RFD is collected at 2:45 p.m. and is 
comprised of a VaR Charge that is based on a snapshot of each 
Netting Member's portfolio collected at noon and, if applicable, an 
Intraday Supplemental Fund Deposit collected after noon.
---------------------------------------------------------------------------

    Pursuant to the GSD Rules, the Intraday Supplemental Fund Deposits 
is determined based on GSD's observations of a Netting Member's 
simulated VaR Charge as it is re-calculated throughout the trading day 
based on the open positions of such Member's portfolio at designated 
times

[[Page 9064]]

(the ``Intraday VaR Charge'').\63\ FICC is proposing to provide 
transparency with respect to its existing authority to calculate and 
assess the Intraday Supplemental Fund Deposit as described in further 
detail below.
---------------------------------------------------------------------------

    \63\ See Rule 4 Section 2a, supra note 4.
---------------------------------------------------------------------------

    The Intraday Supplemental Fund Deposit is designed to mitigate 
exposure to GSD that results from large fluctuations in a Netting 
Member's portfolio due to new and settled trade activities that are not 
otherwise covered by a Netting Member's recently collected Required 
Fund Deposit. FICC determines whether to assess an Intraday 
Supplemental Fund Deposit by tracking three criteria (each, a 
``Parameter Break'') for each Netting Member. The first Parameter Break 
evaluates whether a Netting Member's Intraday VaR Charge equals or 
exceeds a set dollar amount (as determined by FICC from time to time) 
when compared to the VaR Charge that was included in the most recently 
collected Required Fund Deposit including, any subsequently collected 
Intraday Supplemental Fund Deposit (the ``Dollar Threshold''). The 
second Parameter Break evaluates whether the Intraday VaR Charge equals 
or exceeds a percentage increase (as determined by FICC from time to 
time) of the VaR Charge that was included in the most recently 
collected Required Fund Deposit including, if applicable, any 
subsequently collected Intraday Supplemental Fund Deposit (the 
``Percentage Threshold''). The third Parameter Break evaluates whether 
a Netting Member is experiencing backtesting results below the 99% 
confidence level (the ``Coverage Target'').
(a) The Dollar Threshold
    The purpose of the Dollar Threshold is to identify Netting Members 
with additional risk exposures that represent a substantial portion of 
the Clearing Fund. FICC believes these Netting Members pose an 
increased risk of loss to GSD because the coverage provided by the 
Clearing Fund (which is designed to cover the aggregate losses of all 
Netting Members' portfolios) would be substantially impacted by large 
exposures. In other words, in the event that a Netting Member's 
Required Fund Deposit is not sufficient to satisfy losses to GSD caused 
by the liquidation of the defaulted Netting Member's portfolio, FICC 
will use the Clearing Fund to satisfy such losses. However, because the 
Clearing Fund must be available to satisfy potential losses that may 
arise from any Netting Member's defaults, GSD will be exposed to a 
significant risk of loss if a defaulted Netting Member's additional 
risk exposure accounted for a substantial portion of the Clearing Fund.
    The Dollar Threshold is set to an amount that would help to ensure 
that the aggregate additional risk exposure of all Netting Members does 
not exceed 5% of the Clearing Fund. FICC believes that the availability 
of at least 95% of the Clearing Fund to satisfy all other liquidation 
losses caused by a defaulted Netting Member is sufficient to mitigate 
risks posed to FICC by such losses.
    Currently, the Dollar Threshold equals a change in a Netting 
Member's Intraday VaR Charge that equals or exceeds $1,000,000 when 
compared to the VaR Charge that was included in the most recently 
collected Required Fund Deposit including, if applicable, any 
subsequently collected Intraday Supplemental Fund Deposit. On an annual 
basis, FICC assesses the sufficiency of the Dollar Threshold, and may 
adjust the Dollar Threshold if FICC determines that an adjustment is 
necessary to provide GSD with reasonable coverage.
(b) The Percentage Threshold
    The purpose of the Percentage Threshold is to identify Netting 
Members with Intraday VaR Charge amounts that reflect significant 
changes when such amounts are compared to the VaR Charge that was 
included as a component in such Netting Member's most recently 
collected Required Fund Deposit. FICC believes that these Netting 
Members pose an increased risk of loss to GSD because the most recently 
collected VaR Charge (which is designed to cover estimated losses to a 
portfolio over a three-day liquidation period at least 99% of the time) 
may not adequately reflect a Netting Member's portfolio with such 
Netting Member's significant intraday changes in additional risk 
exposure. Thus, in the event that the Netting Member defaults during 
the trading day the Netting Member's most recently collected Required 
Fund Deposit may be insufficient to cover the liquidation of its 
portfolio within a three-day liquidation period.
    Currently, the Percentage Threshold is equal to a Netting Member's 
Intraday VaR Charge that equals or exceeds 100% of the most recently 
calculated VaR Charge included in the most recently collected Required 
Fund Deposit including, if applicable, any subsequently collected 
Intraday Supplemental Fund Deposit. On an annual basis, FICC assesses 
the sufficiency of the Percentage Threshold and may adjust the 
Percentage Threshold if it determines that such adjustment is necessary 
to provide GSD with reasonable coverage.
(c) The Coverage Target
    The purpose of the Coverage Target is to identify Netting Members 
with backtesting results \64\ below the 99% confidence level (i.e., 
greater than two deficiency days in a rolling 12-month period) as 
reported in the most current month. FICC believes that these Netting 
Members pose an increased risk of loss to FICC because their 
backtesting deficiencies demonstrate that GSD' risk-based margin model 
has not performed as expected based on the Netting Member's trading 
activity. Thus, the most recently collected Required Fund Deposit might 
be insufficient to cover the liquidation of a Netting Member's 
portfolio within a three-day liquidation period in the event that such 
Member defaults during the trading day.
---------------------------------------------------------------------------

    \64\ The referenced backtesting results would only reflect the 
Backtesting Charge if such charge is collected in the Required Fund 
Deposit.
---------------------------------------------------------------------------

(d) Assessment and Collection of the Intraday Supplemental Fund 
Deposits
    In the event that FICC determines that a Netting Member's 
additional risk exposure breaches all three Parameter Breaks, FICC will 
assess an Intraday Supplemental Fund Deposit. Should FICC determine 
that certain market conditions exist \65\ FICC would impose an Intraday 
Supplemental Fund Deposit if a Netting Member's Intraday VaR Charge 
breaches the Dollar Amount threshold and the Percentage Threshold 
notwithstanding the fact that the Coverage Target has not been breached 
by such Netting Member.\66\ In addition, during such market conditions, 
the Dollar Threshold and Percentage Threshold may be reduced if FICC 
determines a Netting Member's portfolios may present relatively greater 
risks to FICC since the most recently collected Required Fund Deposit. 
Any such reduction will not cause the Dollar Threshold to be less than 
$250,000 and the Percentage Threshold to be less than 5%.
---------------------------------------------------------------------------

    \65\ Examples include but are not limited to (i) sudden swings 
in an equity index or (ii) movements in the U.S. Treasury yields and 
mortgage-backed securities spreads that are outside of historically 
observed market moves.
    \66\ In certain market condition, a Netting Member's backtesting 
coverage may not accurately reflect the risks posed by such Netting 
Member's portfolio. Therefore, FICC imposes the Intraday 
Supplemental Fund on Netting Members that breach the Dollar 
Threshold and Percentage Threshold, despite the fact that such 
Member may not have breached the Coverage Target during certain 
market conditions.

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

[[Page 9065]]

    FICC has the discretion to waive or change \67\ Intraday 
Supplemental Fund Deposit amounts if it determines that a Netting 
Member's additional risk exposure and/or breach of a Parameter Break 
does not accurately reflect GSD's exposure to the fluctuations in the 
Netting Member's portfolio.\68\ Given that there are numerous factors 
that could result in a Netting Member's additional risk exposure and/or 
breach of a Parameter Break, FICC believes that it is important to 
maintain such discretion in order to help ensure that the Intraday 
Supplemental Fund Deposit is imposed only on Netting Members with 
additional risk exposures that pose a significant level of risk to 
FICC.
---------------------------------------------------------------------------

    \67\ FICC will not reduce the Intraday Supplemental Fund Deposit 
if such reduction will cause the Netting Member's most recently 
collected Required Fund Deposit to decrease. In addition, FICC will 
not increase the Intraday VaR Charge to an amount that is two times 
more than a Netting Member's most recently collected Required Fund 
Deposit.
    \68\ For example, a Netting Member's breach of the Coverage 
Target could be due to a shortened backtesting look-back period and/
or large position fluctuations caused by trading errors.
---------------------------------------------------------------------------

I. Delayed Implementation of the Proposed Rule Change

    This proposed rule change would become operative 45 business days 
after the later date of the Commission's notice of no objection to this 
Advance Notice and its approval of the related proposed rule 
change.\69\ The delayed implementation is designed to give Netting 
Members the opportunity to assess the impact that the proposed rule 
change would have on their Required Fund Deposit.
---------------------------------------------------------------------------

    \69\ See supra note 3.
---------------------------------------------------------------------------

    Prior to the effective date, FICC would add a legend to the GSD 
Rules to state that the specified changes to the GSD Rules are approved 
but not yet operative, and to provide the date such approved changes 
would become operative. The legend would also include the file numbers 
of the approved proposed rule change and Advance Notice Filing and 
would state that once operative, the legend would automatically be 
removed from the GSD Rules.

J. Description of the Proposed Changes to the Text of the GSD Rules

1. Proposed Changes to GSD Rule 1 (Definitions)
    FICC is proposing to amend the term ``Backtesting Charge'' to 
provide that a GCF Counterparty's backtesting deficiencies attributable 
to collateralized mortgage-backed securities during the Blackout Period 
would be considered in FICC's assessment of the applicability of the 
charge. FICC is also proposing to amend the definition of the term 
``Backtesting Charge'' to provide that an Intraday Backtesting Charge 
may be assessed based on the backtesting results of a Netting Member's 
intraday portfolio. In order to differentiate the Intraday Backtesting 
charge from the existing application of the Backtesting Charge, the 
existing charge would be referred to as the ``Regular Backtesting 
Charge.'' As a result of this proposed change, FICC would be permitted 
to assess an Intraday Backtesting Charge based on a Netting Member's 
intraday portfolio and a Regular Backtesting Charge based on a Netting 
Member's end of day portfolio. As a result of this proposed change, 
FICC's calculation of the Intraday Backtesting Charge and the Regular 
Backtesting Charge could include deficiencies attributable to GCF Repo 
Transactions collateralized with mortgage-backed securities during the 
Blackout Period.
    FICC is proposing to add the new defined term ``Blackout Period 
Exposure Adjustment'' to define a new component in the Required Fund 
Deposit calculation. This component would apply to all GCF 
Counterparties with exposure to mortgage-backed securities in their 
portfolio during the Blackout Period.
    FICC is proposing to delete the term ``Blackout Period Exposure 
Charge.'' This component would no longer be necessary because the 
proposed Blackout Period Exposure Adjustment would be applied to all 
GCF Counterparties with exposure to mortgage-backed securities in their 
portfolio.
    FICC is proposing to delete the term ``Coverage Charge'' because 
this component would be eliminated from the Required Fund Deposit 
calculation.
    FICC is proposing to delete the term ``Excess Capital'' because 
FICC is proposing to add the new defined term ``Netting Member 
Capital.''
    FICC is proposing to amend the definition of the term ``Excess 
Capital Ratio'' to reflect the replacement of ``Excess Capital'' with 
``Netting Member Capital.''
    FICC is proposing to change the term ``Intraday Supplemental 
Clearing Fund Deposit'' to ``Intraday Supplemental Fund Deposit'' 
because the latter is consistent with the term that is reflected in GSD 
Rule 4.
    FICC is proposing to amend the term ``Margin Proxy'' to reflect 
that the Margin Proxy would be used as an alternative volatility 
calculation.
    FICC is proposing to add the new defined term ``Netting Member 
Capital'' to reflect the change to the Net Capital for Broker Netting 
Members', Inter-Broker Dealer Netting Members' and Dealer Netting 
Members' calculation of the Excess Capital Ratio.
    FICC is proposing to amend the definition of the term ``VaR 
Charge'' to establish that (1) the Margin Proxy would be utilized as an 
alternative volatility calculation in the event that the requisite data 
used to employ the sensitivity approach is unavailable, and (2) a VaR 
Floor would be utilized as the VaR Charge in the event that the 
proposed model based approach yields an amount that is lower than the 
VaR Floor.
2. Proposed Changes to GSD Rule 4 (Clearing Fund and Loss Allocation)
Proposed Changes to Rule 4 Section 1b
    FICC is proposing to eliminate the reference to ``Coverage Charge'' 
because this component would no longer be included in the Required Fund 
Deposit calculation.
    FICC is proposing to add the ``Blackout Period Exposure 
Adjustment'' because this would be a new component included in the 
Required Fund Deposit calculation.
    FICC is proposing to eliminate the reference to ``Blackout Period 
Exposure Charge'' because this component would no longer be included in 
the Required Fund Deposit calculation.
    FICC is proposing to renumber this section in order to accommodate 
the above-referenced proposed changes.
    FICC is proposing to define ``Net Unsettled Position'' because it 
is a defined term in GSD Rule 1.
    FICC is proposing to amend this section to state that a haircut 
method would be utilized based on the historic index volatility model 
for the purposes of calculating the VaR Charge for classes of 
securities that cannot be handled by the VaR model's methodology.
    FICC is proposing to delete the paragraph relating to the Margin 
Proxy because the Margin Proxy would no longer be used to supplement 
the VaR Charge.

K. Description of the QRM Methodology

    The QRM Methodology document provides the methodology by which FICC 
would calculate the VaR Charge with the proposed sensitivity approach 
as well as other components of the Required Fund Deposit calculation. 
The QRM Methodology document specifies (i) the model inputs, 
parameters, assumptions and qualitative adjustments, (ii) the 
calculation used to generate Required Fund Deposit amounts, (iii) 
additional calculations

[[Page 9066]]

used for benchmarking and monitoring purposes, (iv) theoretical 
analysis, (v) the process by which the VaR methodology was developed as 
well as its application and limitations, (vi) internal business 
requirements associated with the implementation and ongoing monitoring 
of the VaR methodology, (vii) the model change management process and 
governance framework (which includes the escalation process for adding 
a stressed period to the VaR calculation), (viii) the haircut 
methodology, (ix) the Blackout Period Exposure Adjustment calculations, 
(x) intraday margin calculation, and (xi) the Margin Proxy calculation.

II. Anticipated Effect on and Management of Risks

    FICC believes that the proposed change to the Required Fund Deposit 
calculation, which consists of proposals to (1) change its method of 
calculating the VaR Charge component, (2) add a new component referred 
to as the Blackout Period Exposure Adjustment, (3) eliminate the 
Blackout Period Exposure Charge and the Coverage Charge components, (4) 
amend the Backtesting Charge component to (i) include the backtesting 
deficiencies of certain GCF Counterparties during the Blackout Period 
and (ii) give GSD the ability to assess the Backtesting Charge on an 
intraday basis for all Netting Members, and (5) amend the calculation 
for determining the Excess Capital Premium for Broker Netting Members, 
Inter-Dealer Broker Netting Members and Dealer Netting Members, would 
enable FICC to better limit its exposure to Netting Members arising out 
of the activity in their portfolios.

A. Proposed Changes to GSD's Calculation of the VaR Charge

1. Proposed Change To Replace the Full Revaluation Approach With the 
Sensitivity Approach
    FICC's proposal to change the existing VaR methodology from one 
that employs a full revaluation approach to one that employs a 
sensitivity approach would affect FICC's management of risk by 
addressing the deficiencies observed in the current model by leveraging 
external vendor expertise in supplying the market risk attributes that 
would then be incorporated by FICC into its model to calculate the VaR 
Charge to Members. The proposed methodology would enhance FICC's risk 
management capabilities because it would enable sensitivity analysis of 
key model parameters and assumptions. The sensitivity approach would 
allow FICC to attribute market price moves to various risk factors 
(such as key rates, agency spread, and mortgage basis) that would 
enable FICC to view and respond more effectively to market volatility.
    As noted above, the proposed sensitivity approach would leverage 
external vendor expertise in supplying the market risk attributes. FICC 
would manage the risks associated with a potential data disruption by 
using the most recently available data on the first day that a data 
disruption occurs. If it is determined that the vendor would resume 
providing data within five (5) business days, FICC management would 
determine whether the VaR Charge should continue to be calculated by 
using the most recently available data along with an extended look-back 
period or whether the Margin Proxy should be invoked.
2. Proposed Change To Amend the VaR Charge To Eliminate the Augmented 
Volatility Adjustment Multiplier
    FICC's proposal to eliminate the augmented volatility adjustment 
multiplier would affect FICC's management of risk because the augmented 
volatility adjustment multiplier would no longer be necessary given 
that the proposed sensitivity approach would have a longer look-back 
period and the ability to include an additional stressed market 
condition to account for periods of market volatility. As described in 
Item II.(B)I. above, the proposed sensitivity approach would provide 
FICC with the ability to leverage a 10-year look-back period plus, to 
the extent applicable, an additional stressed period for purposes of 
calculating the VaR Charge. FICC's ability to extend the look back 
period would help to ensure that the historical simulation contains a 
sufficient number of market conditions (including but not limited to 
stressed market conditions), which would allow FICC to manage risks by 
more effectively capturing the risk profile of Netting Members during 
times of market stress.
3. Proposed Change To Implement the Margin Proxy as the VaR Charge 
During a Vendor Data Disruption
    FICC's proposal to employ the Margin Proxy as an alternative 
volatility calculation rather than as a minimum volatility calculation 
would affect FICC's management of risk by helping to ensure that FICC 
has a margin methodology in place that effectively measures FICC's 
exposure to Netting Members in the event that a vendor data disruption 
reduces the reliability of the margin amount calculated by the proposed 
sensitivity-based VaR model.
    As described in Item II.(B)I. above, if the vendor fails to provide 
any data or a significant portion of the data timely, FICC would use 
the most recently available data on the first day that such data 
disruption occurs. If it is determined that the vendor will resume 
providing data within five (5) business days, FICC management would 
determine whether the VaR Charge should continue to be calculated by 
using the most recently available data along with an extended look-back 
period or whether the Margin Proxy should be invoked, subject to the 
approval of DTCC's Group Chief Risk Officer or his/her designee. If it 
is determined that the data disruption will extend beyond five (5) 
business days, the Margin Proxy would be applied, subject to the 
approval of the MRC followed by notification to FICC's Board Risk 
Committee.
4. Proposed Change To Utilize a Haircut Method To Measure the Risk 
Exposure of Securities That Lack Historical Data
    FICC's proposal to implement a haircut method for securities that 
lack sufficient historical information would affect FICC's management 
of risk because the proposed change would better describe FICC's method 
of capturing the risk profile of these securities, thus helping to 
ensure that sufficient margin would be calculated for the related 
portfolios. FICC would continue to manage the market risk of clearing 
securities with inadequate historical data by conducting analysis on 
the type of securities that do not fall within the historical look-back 
period of the proposed VaR model and engaging in periodic reviews of 
the haircuts used for calculating margin for these types of securities.
5. Proposed Change To Amend the VaR Charge Calculation To Establish a 
VaR Floor
    FICC's proposal to implement the VaR Floor would affect FICC's 
management of risk because the proposed VaR Floor would address a risk 
that the proposed sensitivity approach could calculate a VaR Charge 
that is too low in connection with certain portfolios where the 
proposed VaR model applies substantial risk offsets among long and 
short positions in different classes of securities that have historical 
price correlation. Since this level of historical price correlation may 
not apply in future changing market conditions, FICC believes that it 
is prudent to apply a VaR Floor that is based upon the market value of 
the gross of unsettled positions in the Netting Member's portfolio. The 
VaR Floor would therefore provide GSD

[[Page 9067]]

with sufficient margin in the event that FICC is required to liquidate 
in different market conditions.

B. Proposed Change To Establish the Blackout Period Exposure Adjustment 
as a Component to the Required Fund Deposit Calculation

    FICC's proposal to establish the Blackout Period Exposure 
Adjustment would affect FICC's management of risk because the Blackout 
Period Exposure Adjustment would better protect GSD and its Netting 
Members from losses that could result from overstated values of 
mortgage-backed securities pledged as collateral for GCF Repo 
Transactions during the Blackout Period. FICC believes that the 
proposed adjustment would help to maintain GCF Counterparties' 
backtesting coverage above the 99% confidence threshold because the 
proposed Blackout Period Exposure Adjustment would be applied to the 
VaR Charge for all GCF Counterparties with GCF Repo Transactions 
collateralized with mortgage-backed securities during the monthly 
Blackout Period. In the event that a GCF Counterparty continues to 
experience backtesting deficiencies, FICC would apply the existing 
Backtesting Charge pursuant to the GSD Rules, which would be amended to 
consider deficiencies attributable to Blackout Period exposures during 
the Blackout Period.

C. Proposed Change To Eliminate the Coverage Charge From the Required 
Fund Deposit Calculation

    FICC's proposal to eliminate the Coverage Charge component from 
GSD's Required Fund Deposit calculation would affect FICC's management 
of risk because the proposed change would remove an unnecessary 
component from the Required Fund Deposit calculation. As described 
above, the Coverage Charge is based on historical portfolio activity, 
which may not be indicative of a Netting Member's current risk profile 
but was determined by FICC to be appropriate to address potential 
shortfalls in margin charges under the current VaR model. As part of 
FICC's development and assessment of the proposed VaR Charge, FICC 
obtained an independent validation of the proposed model by an external 
party, performed back testing to validate model performance, and 
conducted analysis to determine the impact of the changes to Netting 
Members. Results of the analysis indicate that the proposed sensitivity 
approach would be more responsive to changing market dynamics and 
provide better coverage than the existing full revaluation approach. 
Given the proposed improvement in model coverage, FICC believes that 
the Coverage Charge component would no longer be necessary.

D. Proposed Change To Eliminate the Existing Blackout Period Exposure 
Charge

    The proposed Blackout Period Exposure Adjustment would allow GSD to 
eliminate the existing Blackout Period Exposure Charge because the 
proposed Blackout Period Exposure Adjustment would be applied to all 
GCF Counterparties with GCF Repo Transactions collateralized with 
mortgage-backed securities during the Blackout Period, while the 
existing Blackout Period Exposure Charge only applies to GCF 
Counterparties that have two or more backtesting deficiencies that 
occurred during the Blackout Period and whose overall 12-month trailing 
backtesting coverage falls below the 99% coverage target. FICC believes 
that the proposed Blackout Period Exposure Adjustment would help to 
maintain GCF Counterparties' backtesting coverage above the 99% 
confidence threshold. In the event that a GCF Counterparty continues to 
experience backtesting deficiencies, FICC would apply the existing 
Backtesting Charge pursuant to the GSD Rules. As described below, the 
Backtesting Charge would be amended to include deficiencies related to 
Blackout Period Exposure during the Blackout Period. Given the proposed 
Blackout Period Exposure Adjustment and the amendment of the 
Backtesting Charge, FICC believes that the existing Blackout Period 
Exposure Charge component would no longer be necessary.

E. Proposed Change To Expand GSD's Authority To Assess the Backtesting 
Charge and Amend the Charge During the Blackout Period

    FICC's proposal to assess an Intraday Backtesting Charge on a 
Netting Member's portfolio during the trading day would affect FICC's 
management of risk because it would address the risk that a Netting 
Member's most recently collect Required Fund Deposit may be 
insufficient to cover its intraday trading activity. Thus, the proposed 
change would give FICC the ability to better limit its credit exposures 
to Netting Members on an intraday basis.
    FICC's proposal to amend the charge to consider deficiencies 
attributable to Blackout Period exposures would be included only during 
the Blackout Period would address the risk that a defaulted GCF 
Counterparty's portfolio contains exposure to GCF Transactions 
collateralized with mortgage-backed securities that is not adequately 
captured by the GCF Counterparty's Required Fund Deposit. Thus, the 
proposed change would allow FICC to continue to maintain coverage of 
FICC's credit exposures to such GCF Repo Participant at a high degree 
of confidence during the period when this risk regarding the valuation 
of such GCF Transactions could exist.

F. Proposed Change to the Excess Capital Premium Calculation for Broker 
Netting Members, Inter-Dealer Broker Netting Members and Dealer Netting

    FICC believes that the proposed change to move to a net capital 
measure for Broker Netting Members, Inter-Dealer Broker Netting Members 
and Dealer Netting Members would affect FICC's management of risk 
because the proposed change would better align the Excess Capital 
Premium for Broker Netting Members, Inter-Dealer Broker Netting Members 
and Dealer Netting Members to a measure that would be consistent with 
the equity capital measure that is currently used for Bank Netting 
Members in the Excess Capital Premium calculation, while continuing to 
provide an effective means to manage risks posed by a Netting Member 
whose activity causes it to have VaR Charge that is greater than its 
regulatory capital.

G. GSD's Existing Calculation and Assessment of Intraday Supplemental 
Fund Deposit Amounts

    FICC's proposal to provide transparency with respect to GSD's 
current practice of calculating Intraday Supplemental Fund Deposits 
would affect FICC's management of risk because it would help Netting 
Members understand the process and circumstances under which GSD may 
collect Intraday Supplemental Fund Deposit from Netting Members. The 
collection of Intraday Supplemental Fund Deposits is designed to 
mitigate FICC's exposure resulting from large intraday fluctuations in 
Netting Members' portfolios due to new and settled trade activities.

H. FICC's Outreach to GSD Netting Members

    FICC managed the effect of the overall proposal by conducting 
extensive outreach with Netting Members regarding the proposed changes, 
educating Netting Members on the reasons for these proposed changes, 
and explaining the related risk management improvements. FICC invited 
all Netting Members to customer forums in an effort to provide 
transparency regarding the changes and the expected macro

[[Page 9068]]

impact across the membership. FICC also provided each Netting Member 
with individual impact studies. In addition, prior to the 
implementation of the proposed changes, FICC would run a parallel 
period during which Netting Members would have the opportunity to 
further review the possible impact.

III. Consistency With the Clearing Supervision Act

    Although the Clearing Supervision Act does not specify a standard 
of review for an advance notice, its stated purpose is instructive: To 
mitigate systemic risk in the financial system and promote financial 
stability by, among other things, promoting uniform risk management 
standards for systemically important financial market utilities and 
strengthening the liquidity of systemically important financial market 
utilities.\70\
---------------------------------------------------------------------------

    \70\ See 12 U.S.C. 5461(b).
---------------------------------------------------------------------------

    Section 805(a)(2) of the Clearing Supervision Act \71\ authorizes 
the Commission to prescribe risk management standards for the payment, 
clearing and settlement activities of designated clearing entities, 
like FICC, and financial institutions engaged in designated activities 
for which the Commission is the supervisory agency or the appropriate 
financial regulator. Section 805(b) of the Clearing Supervision Act 
\72\ states that the objectives and principles for the risk management 
standards prescribed under Section 805(a) shall be to, among other 
things, promote robust risk management, promote safety and soundness, 
reduce systemic risks, and support the stability of the broader 
financial system. The Commission has adopted risk management standards 
under Section 805(a)(2) of the Clearing Supervision Act \73\ and 
Section 17A of the Exchange Act (``Covered Clearing Agency 
Standards'').\74\ The Covered Clearing Agency Standards require 
registered clearing agencies to establish, implement, maintain, and 
enforce written policies and procedures that are reasonably designed to 
meet certain minimum requirements for their operations and risk 
management practices on an ongoing basis.\75\

(i) Consistency With Section 805(b) of the Clearing Supervision Act

    For the reasons described below, FICC believes that the proposed 
changes in this advance notice are consistent with the objectives and 
principles of these risk management standards as described in Section 
805(b) of the Clearing Supervision Act and in the Covered Clearing 
Agency Standards.
    As discussed above, FICC is proposing a number of changes to GSD's 
Required Fund Deposit calculation--a key tool that FICC uses to 
mitigate potential losses to FICC associated with liquidating a Netting 
Member's portfolio in the event of Netting Member default. FICC 
believes the proposed changes are consistent with promoting robust risk 
management because they are designed to enable FICC to better limit its 
exposure to Members in the event of a Member default. Specifically, (1) 
the proposed change to utilize the sensitivity approach would enable 
FICC to better limit its exposure to Netting Members because the 
sensitivity approach would incorporate a broad range of structured risk 
factors as well as an extended look-back period that would calculate 
better margin coverage for FICC, (2) the proposed use of the Margin 
Proxy as an alternative volatility calculation would enable FICC to 
better limit its exposure to Netting Members because it would help to 
ensure that FICC has a margin methodology in place that effectively 
measures FICC's exposure to Netting Members in the event that a vendor 
data disruption reduces the reliability of the margin amount calculated 
by the proposed sensitivity-based VaR model, (3) the proposed haircut 
method would enable FICC to better limit its exposure to Netting 
Members because it would provide a better assessment of the risks 
associated with classes of securities with inadequate historical 
pricing data, (4) the proposed VaR Floor would enable FICC to better 
limit its exposure to Netting Members because it would help to ensure 
that each Netting Member has a minimum VaR Charge in the event that the 
proposed VaR model utilizing the sensitivity approach yields too low a 
VaR Charge for such portfolios, (5) the proposal to add the proposed 
Blackout Period Exposure Adjustment as a new component and the proposal 
to amend the Backtesting Charge to consider backtesting deficiencies 
attributable to GCF Repo Transactions collateralized with mortgage-
backed securities during the Blackout Period would enable FICC to 
better limit its exposure to Netting Members because these changes 
would help to ensure that FICC collects sufficient margin from GCF 
Counterparties with GCF Repo Transactions collateralized mortgage-
backed securities with risk characteristics that are not effectively 
captured by the Required Fund Deposit calculation during the Blackout 
Period, (6) the proposed Intraday Backtesting Charge would enable FICC 
to better limit its exposure to Netting Members because it would help 
to ensure that FICC collects appropriate margin from Netting Members 
that have backtesting deficiencies during the trading day due to large 
fluctuations of intraday trading activity that could pose risk to FICC 
in the event that such Netting Members defaults during the trading day, 
and (7) the proposed change to the Excess Capital Premium calculation 
would enable FICC to better limit its exposure to Netting Members 
because it would help to ensure that FICC does not unnecessarily 
increase its calculation and collection of Required Fund Deposit 
amounts for Broker Netting Members, Inter-Dealer Broker Netting Members 
and Dealer Netting Members. Finally, FICC's proposal to eliminate the 
Blackout Period Exposure Charge, Coverage Charge and augmented 
volatility adjustment multiplier would enable FICC to eliminate 
components that do not measure risk as accurately as the proposed and 
existing risk management measures, as described above.
    Therefore, because the proposal is designed to enable FICC to 
better limit its exposure to Netting Members in the manner described 
above, FICC believes it is consistent with promoting robust risk 
management.
    Furthermore, FICC believes that the changes proposed in this 
advance notice are consistent with promoting safety and soundness, 
which, in turn, is consistent with reducing systemic risks and 
supporting the stability of the broader financial system, consistent 
with Section 805(b) of the Clearing Supervision Act.\76\ As described 
in the second paragraph above, the proposed changes are designed to 
better limit FICC's exposures to Netting Members in the event of a 
Netting Member default. FICC believes that by better limiting its 
exposures to Netting Members in the event of a Netting Member's 
default, the proposed changes are consistent with promoting safety and 
soundness, which, in turn, is consistent with reducing systemic risks 
and supporting the stability of the broader financial system.

(ii) Consistency With Rule 17Ad-22(e)(4)(i) and (e)(6)(i), (ii), (iii), 
(iv) and (v) Under the Act

    FICC believes that the proposed changes listed above are consistent 
with

[[Page 9069]]

Rules 17Ad-22(e)(4)(i) and (e)(6)(i), (ii), (iii), (iv) and (v) of the 
Act.\77\
---------------------------------------------------------------------------

    \77\ See 17 CFR 240.17Ad-22(e)(4)(i) and (e)(6)(i), (ii), (iii), 
(iv) and (v).
---------------------------------------------------------------------------

    Rule 17Ad-22(e)(4)(i) under the Act \78\ requires a clearing agency 
to 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 
exposures arising from its payment, clearing, and settlement processes 
by maintaining sufficient financial resources to cover its credit 
exposure to each participant fully with a high degree of confidence.
---------------------------------------------------------------------------

    \78\ See 17 CFR 240.17Ad-22(e)(4)(i).
---------------------------------------------------------------------------

    FICC believes that the proposed changes described in Item II.(B) I. 
above enhance FICC's ability to identify, measure, monitor and manage 
its credit exposures to Netting Members and those exposures arising 
from its payment, clearing, and settlement processes because the 
proposed changes would collectively help to ensure that FICC maintains 
sufficient financial resources to cover its credit exposure to each 
Netting Member with a high degree of confidence.
    Because each of the proposed changes to FICC's Required Fund 
Deposit calculation would provide FICC with a more effective measure of 
the risks that these calculations were designed to assess, the proposed 
changes would permit FICC to more effectively identify, measure, 
monitor and manage its exposures to market price risk, and would enable 
it to better limit its exposure to potential losses from Netting Member 
default. Specifically, the proposed changes described in Item II.(B)I. 
above are designed to help ensure that GSD appropriately calculates and 
collects margin to cover its credit exposure to each Netting Member 
with a high degree of confidence because (1) the proposed change to 
utilize the sensitivity approach would provide better margin coverage 
for FICC, (2) the proposed use of the Margin Proxy as an alternative 
volatility calculation would help to ensure that FICC has a margin 
methodology in place that effectively measures FICC's exposure to 
Netting Members in the event that a vendor data disruption reduces the 
reliability of the margin amount calculated by the proposed 
sensitivity-based VaR model, (3) the proposed haircut method would 
provide a better assessment of the risks associated with classes of 
securities with inadequate historical pricing data, (4) the proposed 
VaR Floor would limit FICC's credit exposures to Netting Members in the 
event that the proposed VaR model utilizing the sensitivity approach 
yields too low a VaR Charge for such portfolios, (5) the proposal 
eliminates the Blackout Period Exposure, Coverage Charge and augmented 
volatility adjustment multiplier because FICC should not maintain 
elements of the prior model that would unnecessarily increase Netting 
Members' Required Fund Deposits, (6) the proposal to add the proposed 
Blackout Period Exposure Adjustment as a new component would limit 
FICC's credit exposures during the Blackout Period caused by GCF Repo 
Transactions collateralized mortgage-backed securities with risk 
characteristics that are not effectively captured by the Required Fund 
Deposit calculation, (7) the proposal to amend the Backtesting Charge 
to consider backtesting deficiencies attributable to GCF Repo 
Transactions collateralized with mortgage-backed securities during the 
Blackout Period would help to ensure that FICC could cover credit 
exposure to GCF Counterparties, (8) the proposed Intraday Backtesting 
Charge would help to ensure that FICC collects appropriate margin from 
Netting Members that have backtesting deficiencies during the trading 
day due to large fluctuations of intraday trading activity that could 
pose risk to FICC in the event that such Netting Members defaults 
during the trading day, and (9) the proposed change to the Excess 
Capital Premium calculation would help to ensure that FICC does not 
unnecessarily increase its calculation and collection of Required Fund 
Deposit amounts for Broker Netting Members, Inter-Dealer Broker Netting 
Members and Dealer Netting Members.
    The proposed changes would continue to be subject to performance 
reviews by FICC. In the event that FICC's backtesting process reveals 
that the VaR Charge, Required Fund Deposit amounts and/or the Clearing 
Fund do not meet FICC's 99% confidence level, FICC would review its 
margin methodologies and assess whether any changes should be 
considered. Therefore, FICC believes the proposed changes are 
consistent with the requirements of Rule 17Ad-22(e)(4)(i) of the Act 
cited above. Rule 17Ad-22(e)(6)(i) under the Act \79\ requires a 
clearing agency 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, considers, and produces margin levels 
commensurate with, the risks and particular attributes of each relevant 
product, portfolio, and market.
---------------------------------------------------------------------------

    \79\ See 17 CFR 240.17Ad-22(e)(6)(i).
---------------------------------------------------------------------------

    FICC believes that the proposed changes referenced above in the 
second paragraph of this section (each of which have been described in 
detail in Item II.(B)I. above) are consistent with Rule 17Ad-
22(e)(6)(i) of the Act cited above because the proposed changes would 
help to ensure that FICC calculates and collects adequate Required Fund 
Deposit amounts, and that each Netting Member's amount is commensurate 
with the risks and particular attributes of each relevant product, 
portfolio, and market. Specifically, (1) the proposed change to utilize 
the sensitivity approach would provide better margin coverage for FICC, 
(2) the proposed use of the Margin Proxy as an alternative volatility 
calculation would help to ensure that FICC has a margin methodology in 
place that effectively measures FICC's exposure to Netting Members in 
the event that a vendor data disruption reduces the reliability of the 
margin amount calculated by the proposed sensitivity-based VaR model, 
(3) the proposed haircut method would provide a better assessment of 
the risks associated with classes of securities with inadequate 
historical pricing data, (4) the proposed VaR Floor would limit FICC's 
credit exposures to Netting Members in the event that the proposed VaR 
model utilizing the sensitivity approach yields too low a VaR Charge 
for such portfolios, (5) the proposal eliminates the Blackout Period 
Exposure, Coverage Charge and augmented volatility adjustment 
multiplier because FICC should not maintain elements of the prior model 
that would unnecessarily increase Netting Members' Required Fund 
Deposits, (6) the proposal to add the proposed Blackout Period Exposure 
Adjustment as a new component would limit FICC's credit exposures 
during the Blackout Period caused by GCF Repo Transactions 
collateralized mortgage-backed securities with risk characteristics 
that are not effectively captured by the Required Fund Deposit 
calculation, (7) the proposal to amend the Backtesting Charge to 
consider backtesting deficiencies attributable to GCF Repo Transactions 
collateralized with mortgage-backed securities during the Blackout 
Period would help to ensure that FICC could cover credit exposure to 
GCF Counterparties, (8) the proposed Intraday Backtesting Charge would 
help to ensure that FICC collects appropriate margin from Netting 
Members that have backtesting deficiencies during the trading day due

[[Page 9070]]

to large fluctuations of intraday trading activity that could pose risk 
to FICC in the event that such Netting Members defaults during the 
trading day, and (9) the proposed change to the Excess Capital Premium 
calculation would help to ensure that FICC does not unnecessarily 
increase its calculation and collection of Required Fund Deposit 
amounts for Broker Netting Members, Inter-Dealer Broker Netting Members 
and Dealer Netting Members.
    Therefore, FICC believes that the proposed changes are consistent 
with the requirements of Rule 17Ad-22(e)(6)(i) cited above because the 
collective proposed rule changes would consider, and produce margin 
levels commensurate with, the risks and particular attributes of each 
relevant product, portfolio, and market.
    Rule 17Ad-22(e)(6)(ii) under the Act \80\ requires a clearing 
agency 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, marks participant positions to market and collects margin, 
including variation margin or equivalent charges if relevant, at least 
daily and includes the authority and operational capacity to make 
intraday margin calls in defined circumstances.
---------------------------------------------------------------------------

    \80\ See 17 CFR 240.17Ad-22(e)(6)(ii).
---------------------------------------------------------------------------

    FICC believes that the proposed changes are consistent Rule 17Ad-
22(e)(6)(ii) of the Act cited above because the proposed Intraday 
Backtesting Charge would help to ensure that FICC collects appropriate 
margin from Netting Members that have backtesting deficiencies during 
the trading day due to large fluctuations of intraday trading activity 
that could pose risk to FICC in the event that such Netting Members 
defaults during the trading day. Therefore, FICC believes that the 
proposed Intraday Backtesting Charge would provide GSD with the 
authority and operational capacity to make intraday margin calls in a 
manner that is consistent with Rule 17Ad-22(e)(6)(ii) of the Act cited 
above.
    Rule 17Ad-22(e)(6)(iii) under the Act \81\ requires a clearing 
agency 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, calculates margin sufficient to cover its potential future 
exposure to participants in the interval between the last margin 
collection and the close out of positions following a participant 
default.
---------------------------------------------------------------------------

    \81\ See 17 CFR 240.17Ad-22(e)(6)(iii).
---------------------------------------------------------------------------

    FICC believes that the proposed changes are consistent Rule 17Ad-
22(e)(6)(iii) of the Act cited above because the proposed changes are 
designed to calculate Required Fund Deposit amounts that are sufficient 
to cover FICC's potential future exposure to Netting Members in the 
interval between the last margin collection and the close out of 
positions following a participant default. Specifically, (1) the 
proposed change to utilize the sensitivity approach would provide 
better margin coverage for FICC, (2) the proposed use of the Margin 
Proxy as an alternative volatility calculation would help to ensure 
that FICC has a margin methodology in place that effectively measures 
FICC's exposure to Netting Members in the event that a vendor data

classes of securities with inadequate historical pricing data, (4) the 
proposed VaR Floor would limit FICC's credit exposures to Netting 
Members in the event that the proposed VaR model utilizing the 
sensitivity approach yields too low a VaR Charge for such portfolios, 
(5) the proposal eliminates the Blackout Period Exposure, Coverage 
Charge and augmented volatility adjustment multiplier because FICC 
should not maintain elements of the prior model that would 
unnecessarily increase Netting Members' Required Fund Deposits, (6) the 
proposal to add the proposed Blackout Period Exposure Adjustment as a 
new component would limit FICC's credit exposures during the Blackout 
Period caused by GCF Repo Transactions collateralized mortgage-backed 
securities with risk characteristics that are not effectively captured 
by the Required Fund Deposit calculation, (7) the proposal to amend the 
Backtesting Charge to consider backtesting deficiencies attributable to 
GCF Repo Transactions collateralized with mortgage-backed securities 
during the Blackout Period would help to ensure that FICC could cover 
credit exposure to GCF Counterparties, (8) the proposed Intraday 
Backtesting Charge would help to ensure that FICC collects appropriate 
margin from Netting Members that have backtesting deficiencies during 
the trading day due to large fluctuations of intraday trading activity 
that could pose risk to FICC in the event that such Netting Members 
defaults during the trading day, and (9) the proposed change to the 
Excess Capital Premium calculation would help to ensure that FICC does 
not unnecessarily increase its calculation and collection of Required 
Fund Deposit amounts for Broker Netting Members, Inter-Dealer Broker 
Netting Members and Dealer Netting Members.
    Therefore, FICC believes that the proposed changes would be 
consistent with Rule 17Ad-22(e)(6)(iii) of the Act cited above because 
the proposed rules changes would collectively be designed to help 
ensure that FICC calculates Required Fund Deposit amounts that are 
sufficient to cover FICC's potential future exposure to Netting Members 
in the interval between the last margin collection and the close out of 
positions following a participant default.
    Rule 17Ad-22(e)(6)(iv) under the Act \82\ requires a clearing 
agency 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 procedures and 
sound valuation models for addressing circumstances in which pricing 
data are not readily available or reliable.
---------------------------------------------------------------------------

    \82\ See 17 CFR 240.17Ad-22(e)(6)(iv).
---------------------------------------------------------------------------

    FICC believes that the proposed change to implement a haircut 
method for securities that lack sufficient historical information is 
consistent with Rule 17Ad-22(e)(6)(iv) of the Act cited above because 
the proposed change would allow FICC to use appropriate market data to 
estimate an appropriate margin at a 99% confidence level, thus helping 
to ensure that sufficient margin would be calculated for portfolios 
that contain these securities.
    Rule 17Ad-22(e)(6)(v) under the Act \83\ requires a clearing agency 
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 an appropriate method for measuring credit exposure that 
accounts for relevant product risk factors and portfolio effects across 
products.
---------------------------------------------------------------------------

    \83\ See 17 CFR 240.17Ad-22(e)(6)(v).
---------------------------------------------------------------------------

    FICC believes that the proposed changes to implement a haircut 
method for securities that lack sufficient historical information is 
consistent with Rule 17Ad-22(e)(6)(v) of the Act cited above because 
the haircut method would allow FICC to use appropriate market data to 
estimate an appropriate margin at a 99% confident level, thus

[[Page 9071]]

helping to ensure that sufficient margin would be calculated for 
portfolios that contain these securities.
    FICC also believes that its proposal to replace the Blackout Period 
Exposure Charge with the Blackout Period Exposure Adjustment is 
consistent with Rule 17Ad-22(e)(6)(v) of the Act cited above because 
the proposed Blackout Period Exposure Adjustment would limit FICC's 
credit exposures during the Blackout Period caused by portfolios with 
collateralized mortgage-backed securities with risk characteristics 
that are not effectively captured by the Required Fund Deposit 
calculation.
    Therefore, FICC believes that the proposed haircut method and the 
proposed Blackout Period Exposure Adjustment are consistent with Rule 
17Ad-22(e)(6)(v) of the Act cited above because the proposed changes 
appropriate method for measuring credit exposure that accounts for 
relevant product risk factors and portfolio effects across products.

III. Date of Effectiveness of the Advance Notice, and Timing for 
Commission Action

    The proposed change may be implemented if the Commission does not 
object to the proposed change within 60 days of the later of (i) the 
date that the proposed change was filed with the Commission or (ii) the 
date that any additional information requested by the Commission is 
received. The clearing agency shall not implement the proposed change 
if the Commission has any objection to the proposed change.
    The Commission may extend the period for review by an additional 60 
days if the proposed change raises novel or complex issues, subject to 
the Commission providing the clearing agency with prompt written notice 
of the extension. A proposed change may be implemented in less than 60 
days from the date the advance notice is filed, or the date further 
information requested by the Commission is received, if the Commission 
notifies the clearing agency in writing that it does not object to the 
proposed change and authorizes the clearing agency to implement the 
proposed change on an earlier date, subject to any conditions imposed 
by the Commission.
    The clearing agency shall post notice on its website of proposed 
changes that are implemented.
    The proposal shall not take effect until all regulatory actions 
required with respect to the proposal are completed.
